This is for everyone – Accessibility
The web is fundamentally designed for humans to participate with the smallest possible limitations, independent of their hardware, software, language, location, expertise or ability. Volunteers in the Wikimedia Movement have been actively working and supporting inclusion and equal access for a long time.[1] Aligning to Wikimedia's vision[2] and to our principle “This is for everyone”, we aim for our interfaces to be accessible by design.
We'll introduce key accessibility concepts, illustrate how they are supported in the style guide, and provide guidance for you when applying them.
What and why accessibility?
Web accessibility methods ensure that people with impairments or disabilities can perceive, understand, navigate, interact with, and contribute to the products we all create. Just as importantly, many methods improve general usability, resulting in easier-to-use interfaces that are Perceivable, Operable, Understandable and Robust for everyone.
These are the four principles of accessibility from the Web Content Accessibility Guidelines (WCAG) standard[3], version 2.0 onwards. They specify the success criteria for achieved levels of conformance – A, AA and AAA.
In the Wikimedia Design Style Guide and its resources we aim for satisfying all level AA success criteria. Some AAA criteria are not possible to be satisfied for entire websites as they are opposing each other. We also try to balance requirements that enable the widest possible audience under reasonable operation for our non-profit organization. Further, highly specific user group needs might be better covered by specific software products than by the Foundation itself.
Note, that our principles mainly focus on designing for:
- Visual impairment needs
- Motor impairment needs
Other categories like speech impairments don't apply in our graphical user-interface focus; while hearing and cognitive impairments are to be covered on a content level. See for example Simple Wikipedia (English)[4] for being inclusive to users with learning difficulties.
Accessible by design
Colors and color palette – Use of color
Visual, motor
All colors of our palette feature level AA contrast ratio. We're following color-related accessibility rules:
- Never use color as the only means of providing information or requesting an action.
- The combinations of text and its background color must not fall below the WCAG recommended threshold ratio of 4.5:1 for standard text and 3:1 for larger text.
Fonts and typography – Legible and zoomable content
Visual
Choices of typeface, size, style, and spacing of text make it well readable in general and are a must for some to be legible. Our choices advise on minimum font sizes. Those are able to be overridden by user browser preferences – setting fonts in relative CSS units em
or rem
to provide text zooming when needed.
Touch and keyboard interaction – Ensure alternative input methods
Motor
Our components are designed to support different interaction mechanisms, including touch, pointing devices and keyboard.
When touch screens are the main interface, our components' design ensures minimum touch target sizes for happy human fingers. Additionally, users with motor impairments profit from minimum target sizes for pointer inputs too.
Our components feature a strong outline to indicate keyboard focus state. This enables keyboard-bound users to easily navigate the interface.
Icons and images – Provide text alternatives
Visual
When implementing icons and images, you have to define a textual description to enable assistive technology to interpret it, as long as they are not solely used as decorative elements:
Icons have to be provided with SVG title
attributes or with text nodes visible only for screen readers when used in icon-only buttons.
Images have to provide alt
attributes with alternative text. title
attributes are part of the icons in WikimediaUI icon collection, and code in WikimediaUI theme of user-interface library OOUI.
Markup – Follow standards
Visual, motor
Markup for our components is provided in semantic HTML and follows Web Accessibility Initiative's ARIA Authoring practices standard[5, 6]. This lets assistive technology software identify them correctly.
Additionally, it improves machine readability, resulting in better search optimization or alternative content delivery, for example in popular voice interfaces.

Here is a short overview of the differences between HTTP requests that are sent directly to the destination and HTTP requests that are sent via a proxy.
Following is the main figure for this article. It shows the two different packet types:
Direct HTTP requests: Destination IP is the HTTP server and the requested URI shows only the path behind the domain.
HTTP proxy requests: First packet is sent to the proxy. The requested URI shows the complete URL (host + path). The second packet is sent from the proxy to the final destination. And since it is a “real” proxy, both packets are inside its own TCP connection with different source addresses as well.
In both scenarios, the “Host” value in the HTTP request is set to the requested domain. In the case of a proxy, the HTTP X-Forwarded-For header with the client IP address might be inserted.
Note that the arrows in the figure show only the first HTTP packet flow, though it is a bi-directional communication in which the returning packets have the inverse order of source/destination IPs and ports.

As an example, I opened my What-is-my-IP script at http://ip.webernetz.net two times: The first one without a proxy and the second one with a proxy on port 3128. (Note that the proxy server can run on different ports, e.g., 80, 8080, 3128.) The proxy IP came from a free proxy list (link below).

Dear sir, URGENT AND CONFIDENTIAL -------------------------- I write to introduce this important business opportunity to you irespective of the fact that we have not seen or known each other before but I believe that it will be of immense benefit to both of us.Let me formally introduce myself. I am Mr.ABDULLAH NASSER, a Manager of one of the Apex bank here. I got your particulars in my earnst search for a reliable individual who can assist me in this transaction, with the belief in God that you will never let me down.There is an outstanding sum of US$10.2,Million( Ten million two hundred thousand United States Dollars)belonging to late Mr.Andreas B.Smith, a foreigner and miner in the Kruger Gold Co. a geologist by profession. This fund was deposited since 2000 by the deacesed and since 2002 nobody has operated the said account. After going through some old files in the records, I discovered that the owner of this dormant account Mr.Andreas B. Simth does no longer exist and that if I do not remit this fund out urgently, it would be forfeited for nothing. I am contacting you because of the need to involve a foreigner with foreign account and foreign beneficiary. I need your full co-operation to make this work out fine because the management is ready to approve this payment to a foreigner, who has the correct information of this account which I will provide to you. Should this interest you, kindly furnish me with your overseas bank account details including your private phone and fax number for easy comunication. With my position now in the office, I can arrange for the transfer of this fund to any foreign reliable account which you can provide with assurance that this money will be intact pending my physical arrival in your country for sharing. I will destroy all documents of transaction immediately you recieve this fund leaving no trace to any place. and will also use my position and influence to effect legal approvals and onward transfer of the money to your account with appropriate clearance forms of ministries and foreign exchange departments. I have resolved to compensate you by offering a brokerage commission of 20% net pre-transfer expenses you may incure, 5% set aside for general expenses 75% will be for me and I guarantee that all expenses during the transfer are subject to refund. Most importantly, I must emphasize that this business requires utmost confidentiality and trust. We need to go into an agreement that will bind us together and the same will protect our individual interest in the near future. I will apply for annual leave to get a Visa for a trip to your country once this money is transferred into your foreign account.In recognition of your personal executive power and investment opportunities that is abound in your country, do know that I have in mind to establish a genuine business relationship with you in the nearest future, if you will be able to help me. In order to expedite action, let me recieve your approval or reply through the above phone numbers or by e-mail.Please accept my compliments, as I await for your kind response.

I was talking with our school librarian today about why we don’t offer ebooks for students to check out. It came up because I grabbed a real, hardcover library book six weeks ago and had _just_ finished it this week. It’s only 400ish pages, and taking that long to read a short/medium length book was a little embarrassing.
Compared to reading on my phone or my Kindle, it was an eternity. I like the portability of ebooks. I like being able to pull it up on my phone and read a little when I’m sitting, waiting for something. Especially this year, as I move all over the district day to day, carrying another book in my bag is precious space that’s often wasted due to time.
Ebooks sound great, but I got thinking about [Maha Bali’s post on “owning” a domain](http://blog.mahabali.me/blog/educational-technology-2/i-dont-own-my-domain-i-rent-it-dooo/) and [Audrey Watters’ fantastic take](http://hackeducation.com/2016/08/23/domains) (rebuttal?) on the topic. [I even weighed in a little bit](http://blog.ohheybrian.com/2016/08/flipped-learning-as-a-way-to-build-an-online-presence/) on how teachers can start to build that identity.
I don’t want to encourage a culture where ownership is a burden. Moving school libraries to epubs sounds great: access! they’re on their phones anyways! Kindle!…
…but in practice, it’s a school, paying a company to _licence_ titles. Each borrow by a student turns into dollars paid to an outside entity for the privilege of licensing the book. Libraries cannot give the books away or even recoup shrinking budgets by having used book sales. It’s a expenditure, through and through.
All of that, of course, is ignoring the DRM hurdles put on certain publications, which are only accessible through certain platforms. Ebooks aren’t “just like” books, only in bits. It’s a completely new market geared for one thing: making a profit.
At whose expense?

The software does not correctly calculate the size to be used when allocating a buffer, which could lead to a buffer overflow.
In languages such as C, where memory management is the programmer's responsibility, there are many opportunities for error. If the programmer does not properly calculate the size of a buffer, then the buffer may be too small to contain the data that the programmer plans to write - even if the input was properly validated. Any number of problems could produce the incorrect calculation, but when all is said and done, you're going to run head-first into the dreaded buffer overflow.
The following methods are available for detecting incorrect calculation of buffer size vulnerabilities.
Automated Static Analysis. This weakness can often be detected using automated static analysis tools. Many modern tools use data flow analysis or constraint-based techniques to minimize the number of false positives. Automated static analysis generally does not account for environmental considerations when reporting potential errors in buffer calculations. This can make it difficult for users to determine which warnings should be investigated first. For example, an analysis tool might report buffer overflows that originate from command line arguments in a program that is not expected to run with setuid or other special privileges. Detection techniques for buffer-related errors are more mature than for most other weakness types.
Automated Dynamic Analysis. This weakness can be detected using dynamic tools and techniques that interact with the software using large test suites with many diverse inputs, such as fuzz testing (fuzzing), robustness testing, and fault injection. The software's operation may slow down, but it should not become unstable, crash, or generate incorrect results. Without visibility into the code, black box methods may not be able to sufficiently distinguish this weakness from others, requiring follow-up manual methods to diagnose the underlying problem.
The following mitigation methods for incorrect calculation of buffer size vulnerabilities are available:
Allocate sufficient memory. If you allocate a buffer for the purpose of transforming, converting, or encoding an input, make sure that you allocate enough memory to handle the largest possible encoding. For example, in a routine that converts "&" characters to "&" for HTML entity encoding, you will need an output buffer that is at least 5 times as large as the input buffer. When processing structured incoming data containing a size field followed by raw data, ensure that you identify and resolve any inconsistencies between the size field and the actual size of the data (CWE-130). When allocating memory that uses sentinels to mark the end of a data structure - such as NUL bytes in strings - make sure you also include the sentinel in your calculation of the total amount of memory that must be allocated. Use sizeof() on the appropriate data type to avoid CWE-467.
Understand your programming language's underlying representation and how it interacts with numeric calculation (CWE-681). Pay close attention to byte size discrepancies, precision, signed/unsigned distinctions, truncation, conversion and casting between types, "not-a-number" calculations, and how your language handles numbers that are too large or too small for its underlying representation. Also be careful to account for 32-bit, 64-bit, and other potential differences that may affect the numeric representation.
Perform input validation on any numeric input by ensuring that it is within the expected range. Enforce that the input meets both the minimum and maximum requirements for the expected range.
Use server-side security controls. For any security checks that are performed on the client side, ensure that these checks are duplicated on the server side, in order to avoid CWE-602. Attackers can bypass the client-side checks by modifying values after the checks have been performed, or by changing the client to remove the client-side checks entirely. Then, these modified values would be submitted to the server.
Avoid dangerous APIs. Replace unbounded copy functions with analogous functions that support length arguments, such as strcpy with strncpy. Create these if they are not available. Notes: This approach is still susceptible to calculation errors, including issues such as off-by-one errors (CWE-193) and incorrectly calculating buffer lengths (CWE-131). Additionally, this only addresses potential overflow issues. Resource consumption / exhaustion issues are still possible.
Use the correct variable type. Use the appropriate type for the desired action. For example, in C/C++, only use unsigned types for values that could never be negative, such as height, width, or other numbers related to quantity. This will simplify your sanity checks and will reduce surprises related to unexpected casting.
Use a secure framework. Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid. Use libraries or frameworks that make it easier to handle numbers without unexpected consequences, or buffer allocation routines that automatically track buffer size. Examples include safe integer handling packages such as SafeInt (C++) or IntegerLib (C or C++).
Use compiler features. Run or compile your software using features or extensions that automatically provide a protection mechanism that mitigates or eliminates buffer overflows. For example, certain compilers and extensions provide automatic
buffer overflow detection mechanisms that are built into the compiled code. Examples include the Microsoft Visual Studio
/GS flag, Fedora/Red Hat FORTIFY_SOURCE GCC flag, StackGuard, and
ProPolice.
Note: This is not necessarily a complete solution, since these mechanisms can only detect certain types of overflows. In addition, an attack could still cause a denial of service, since the typical response is to exit the application. Examine
compiler warnings closely and eliminate problems with potential security implications, such as signed / unsigned mismatch in memory operations, or use of uninitialized variables. Even if the weakness is rarely exploitable, a single failure may lead to the
compromise of the entire system.
Use OS buffer overflow protection. Use a feature like Address Space Layout Randomization (ASLR). Use a CPU and operating system that offers Data Execution Protection (NX) or its equivalent.
Use the least privilege principle. Run your code using the lowest privileges that are required to accomplish the necessary tasks. If possible, create isolated accounts with limited privileges that are only used for a single task. That way, a successful attack will not immediately give the attacker access to the rest of the software or its environment. For example, database applications rarely need to run as the database administrator, especially in day-to-day operations.
Use a sandbox. Run your code in a "jail" or similar sandbox environment that enforces strict boundaries between the process and the operating system. This may effectively restrict which files can be accessed in a particular directory or
which commands can be executed by your software. OS-level examples include the Unix
chroot jail, AppArmor, and SELinux. In general, managed code may provide some protection. For example,
java.io.FilePermission in the Java SecurityManager allows you to specify restrictions on file operations. This may not be a feasible solution, and it only limits the impact to the operating system; the rest of your application may still be
subject to compromise. Be careful to avoid CWE-243 and other weaknesses related to jails.
Note: The effectiveness of this mitigation depends on the prevention capabilities of the specific sandbox or jail being used and might only help to reduce the scope of an attack, such as restricting the attacker to certain system calls or limiting
the portion of the file system that can be accessed.


Shropshire maternity scandal: Babies and mothers died amid ‘toxic’ culture at NHS trust
Babies and mothers died amid major failings at Shropshire's hospital trust in what is likely to be the NHS’s worst ever maternity scandal.
A leaked report shows that a “toxic” culture stretching back 40 years was in place when babies and mothers suffered avoidable death.
Children were also left with permanent disability amid substandard care at Shrewsbury and Telford Hospital NHS Trust.
Staff at the trust routinely dismissed parents’ concerns, were unkind, got dead babies’ names wrong and, in one instance, referred to a baby who died as “it”.
In another case, parents were not told their baby’s body had arrived back from the post-mortem examination, and it was left to decompose so badly that the family never got to say a final goodbye.
The interim update report, which has been obtained by The Independent, comes from an independent inquiry ordered by the Government in July 2017.
The study warns that, even to the present day, lessons are not being learned and staff at the trust are uncommunicative with families.
It also points to an inadequate review carried out by the Royal College of Obstetricians and Gynaecologists (RCOG) in 2017 and the “misplaced” optimism of the regulator in charge in 2007.
Scope
The inquiry, which is being led by maternity expert Donna Ockenden, was launched by former health secretary Jeremy Hunt.
Its initial scope was to examine 23 cases but this has now grown to more than 270 covering the period 1979 to the present day.
The cases include 22 stillbirths, three deaths during pregnancy, 17 deaths of babies after birth, three deaths of mothers, 47 cases of substandard care and 51 cases of cerebral palsy or brain damage.
The interim report written by Ms Ockenden for NHS Improvement and the trust – seen by the PA news agency – details the pain suffered by the families.
It points to:
- Babies left brain-damaged because staff failed to realise or act upon signs that labour was going wrong.
- A failure to adequately monitor heartbeats during labour or assess risks during pregnancy, resulting in the deaths of some children.
- Babies left brain-damaged from group B strep or meningitis that can often be treated by antibiotics.
- A baby whose death from group B strep could have been prevented after its parents contacted the trust on several occasions worried about their newborn baby.
- Many families “struggling” to get answers from the trust around “very serious clinical incidents” for many years and continuing to the present day.
- One father whose only feedback following his daughter’s death was when he bumped into a hospital employee in Asda.
- One parent reporting a “closed culture” at the trust over hospital fears of being sued.
- Families who told how “the trust made mistakes with their baby’s name and on occasions referred to a deceased baby as ‘it'”.
- Multiple families “where deceased babies are given the wrong names by the trust – frequently in writing”.
- One family who was told they would have to leave if they did not “keep the noise down” when they were upset following the death of their baby.
- One baby girl’s shawl was lost by staff after her death even though her mother had wanted to bury her in it.
- The “misplaced” optimism of the regulator the Healthcare Commission (a predecessor to the Care Quality Commission) that maternity services would improve following its interjection in 2007.
- Families who were advised “they were the only family”, and that “lessons would be learned”. The report said “it is clear this is not correct”.
- A “long-term failure” to involve families in serious incident investigations, some of which were “overly defensive of staff”.
The inquiry was launched following the efforts of Rhiannon and Richard Stanton Davies, whose daughter Kate died shortly after birth in 2009, and Kayleigh and Colin Griffiths, whose daughter Pippa died shortly after birth in 2016.
Ms Davies told The Independent the leaked report showed the trust’s chronic inability to learn from past mistakes had “condemned my daughter to death”, adding: “How has this been tolerated for so long? It is horrific.”
In the report, Mrs Ockenden wrote: “No apology will be sufficient or adequate for families who lost loved ones to avoidable deaths, or whose experience of becoming a parent was blighted by poor care and avoidable harm.
“Many families have described to me how they live on a daily basis with the results of that poor care.”
The report also criticised the trust’s slow response in sending the inquiry medical records, clinical notes and other documents.
This afternoon, Ms Ockenden said: "The document referred to in today’s coverage appears to be an internal status update as of February 2019. This was produced at the request of NHS Improvement and was not meant for publication.
"At the time I listened to the families involved in the maternity review who were very clear they wanted one, single, comprehensive independent report covering all known cases of potentially serious concern within maternity services at the Trust. My independent review team and I are working hard to achieve this."
Response from Shrewsbury and Telford Hospital NHS Trust
Paula Clark, interim chief executive at The Shrewsbury and Telford Hospital NHS Trust, said: “We have been working, and continue to work, with the independent review into our maternity services.
“On behalf of the trust, I apologise unreservedly to the families who have been affected. I would like to reassure all families using our maternity services that we have not been waiting for Donna Ockenden’s final report before working to improve our services. A lot has already been done to address the issues raised by previous cases.
“Our focus is to make our maternity service the safest it can be. We still have further to go but are seeing some positive outcomes from the work we have done to date.”
“We have not seen or been made aware of any interim report, and await the findings of Donna Ockenden’s report so that we can work with families, our communities and NHS England/Improvement to understand and apply all of the learning identified.”
Until now, Morecambe Bay, which saw the avoidable deaths of 11 babies and one mother at Cumbria’s Furness General Hospital between 2004 and 2013, was the worst ever maternity scandal in the history of the NHS.
Bill Kirkup, who chaired the Morecambe Bay inquiry, told The Independent the interim review made for “ghastly” reading and showed “unmistakeable parallels” with the scandal at Morecambe.


For the fig-swirl: Melt butter over medium heat in a saucepan. Add brown sugar and stir to dissolve. Halve all of the figs and toss in the saucepan with water and lemon juice. Cook over medium heat, stirring frequently, until you have a chunky-jammy mixture. Add salt with one or two stirs, set aside and let cool completely.
Ice cream: In a small pot over medium heat, combine milk, granulated sugar until sugar is completely dissolved and the milk is just barely lukewarm. Whisk in the egg yolks. Set mixture in the fridge and wait until the fig mixture is cooled.
Using and ice cream machine, pour liquids into the frozen basin and process according to manufacturer instructions, i.e., let spin and thicken for 20 minutes before adding mascarpone, fig jam mixture, and the nuts. Continue to process for +/- 10 minutes. Pour semi-frozen mixture into a pyrex dish or glass tupperware. Freeze for at least two hours before serving.

Champion of Champions: Neil Robertson beats Judd Trump 10-9 in dramatic final
World number four Neil Robertson won a dramatic Champion of Champions final by beating Judd Trump 10-9.
In a high-quality match in Coventry, Robertson led the world number one 5-4 at the end of the afternoon session.
The players were then locked at 8-8 when Trump got a snooker he needed and cleared up from the blue to go 9-8 up.
Robertson needed a snooker in the next and got it before potting a re-spotted black to take the match into a decider, which he won with a 137 break.
It was the Australian's fifth century of the match and helped earn him the £150,000 top prize.
"I can't believe the pair of us playing a match like that. It's the best match I've ever been involved in," said Robertson.
"It had everything. I dug in really deep to force a decider."
Trump, who hit three centuries, was left to rue a missed red into the middle pocket when he was on the brink of victory at 9-8 up and on a break of 69.
It allowed Robertson back into the match as he got a snooker, and he potted the remaining reds with the black to tie the scores and secured the frame with a re-spotted black.
"The standard was very good throughout," said Trump. "Overall, I thought Neil deserved to win. he played the better snooker over the two sessions.
"I'm not too disappointed. It was a game I enjoyed. Disappointed to lose from the position I was in but onwards and upwards."

tldr: I created an open dataset for the explicit practice of data munging. Feel free to use it in assignments, but do mention where you got it from (CC-by-4.0). Also unicorns are awesome.
Find the dataset at: https://github.com/RMHogervorst/unicorns_on_unicycles
Data munging / cleaning / engineering At work I was working with a two excel files that were slightly different but could be combined into 1 dataset. This is very typical for day to day cleaning operations that analysts and data scientists do (statisticians too).

Adding logging to a shiny app with loggit
This is a very short post with example code Over time when you move your shiny app from your computer to a server, you want to add some logging. Generally logging is defined in levels : INFO (everything you want to print), WARNING (it does not stop the application, but it could be a problem), and ERROR (fatal things).
Shiny server does already log all it’s actions to a file on the server, but that file can be hard to access.

Setting up a version controlled shiny-server
Last week I set up a shiny server, it was relatively easy! But I wanted something more, a way to make changes on my local computer and push it to the server.
Shiny server (I used the open source version) has multiple installers provided by RStudio.
The installers for shiny-server create a user shiny and installs all the services needed.
I used a guide specific for my version of linux to install shiny-server and combined it with two other guides to make it version controlled.

Moving parts of a country over a map
I love making maps, I also love making gifs. In this short post I make an animated gif of parts of a map moving. In this case the parts of the map only move in the xy direction, but you can also turn them, and make them bigger or smaller. Today I show you how I made a part of the Netherlands ‘float away’. It is part of a larger nonsense project (I have many silly projects), and mostly just to document my path to learning about spatial analytics.

add abbreviations to your rmarkdown doc
Today a small tip for when you write rmarkdown documents. Add a chunk on top with abbreviations.
in the first chunks you set the options and load the packages. Next create abbreviations, you don’t have to care about the ordering, just put them down as you realize you are creating them.
The first step makes a dataframe (a tibble, rowwise), and the second step orders them.

Adding bananas from the commandline (extending the oomsifier)
Sometimes you just want to add bananas from the commandline. Previously I created a small script that takes an image and adds a dancing banana to the bottom left of the image. I wanted to make an API too, but that will have to wait till next year. Today we will create a commandline script that will do the same thing.
With the excellent explanation in Mark Sellors’ guide I have now created a cmdline thingy in very few steps.

If blogging was like academia, we would all be saved, thank you for your edits.
A month ago I posted a short piece inspired by a post by Maële Salmon She actually reached out to me in 10 minutes, telling me I made a weird spelling error (no excuses, I really make those a lot). Then a day or two later Jon Spring walked through the code and realized that I switched two outcomes in the code.
Just about 10 days ago I posted about downloading multiple files and Mara Avarick noticed a weird ‘<<<<<<’ sign on my website.

Downloading files from a webserver, and failing.
Recently I wanted to download all the transcripts of a podcast (600+ episodes). The transcripts are simple txt files so in a way I am not even ‘web’-scraping but just reading in 600 or so text files which is not really a big deal. I thought.
This post shows you where I went wrong
Also here is a picture I found of scraping.
Webscraping general For every download you ask the server for a file and it returns the file (this is also how you normally browse the web btw, your browser requests the pages).

Building the oomsifyer
Today I will show you a quick hack (OK it took me like 4 hours during my travels today yesterday and today), on how to add a dancing banana to any picture.
Now, you might be thinking… Really, why would you add a dancing banana to a picture, but I don’t have time for that kind of negativity in my life.
Why oomsifier? Jeroen Ooms is one of those crazy productive people in the R world.

Where to live in the Netherlands based on temperature XKCD style
After seeing a plot of best places to live in Spain and the USA based on the weather, I had to chime in and do the same thing for the Netherlands. The idea is simple, determine where you want to live based on your temperature preferences.
First the end result: How to read this plot?
In this xkcd comic we see that the topleft of the the graph represents “if you hate cold and hate heat”, if you go down from the topleft to the bottom left the winters get colder and ending in “if you love cold and hate heat”.

Preston's Big PNE Sleep Out smashes £50k target
by David NowellHundreds of people who slept out in the cold overnight to boost an appeal to tackle homelessness in Preston have helped to smash the Big PNE Sleep Out’s £50,000 target.
After more than 2,500 donations and a huge turnout from people all spending Friday night outdoors at Preston’s Deepdale stadium, the appeal is now soaring past the original target mark.
All monies raised will be used by the Foxton Centre to buy and renovate a house in Preston for rough sleepers in the city.
The sleep out was held to mark the Foxton Centre’s 50th anniversary, and was supported by PNE, BIFFA and Blog Preston.
Around 300 people turned out on Friday night armed with multiple layers of clothing and sleeping bags to experience what it is like to have no home or warm bed at night.
Those taking part included business people, campaigners and members of Preston City Council’s cabinet.
They spent a very chilly night on a concourse at Deepdale, lying on top of carboard “matresses”.
Among those supporting the appeal was injured PNE striker Louis Moult.
Louis has been out of action since August with a knee injury and doctor’s orders prevented him from sleeping out.
But he turnd out to give the event his whole-hearted support.
He said: “I’ve seen the brilliant work the Foxton Centre is doing and want to do everything I can to raise awareness.
“The response to the appeal has been fantastic.”
Preston North End tweeted today: “An incredible £50,000 has been raised for The Foxton Centre
“A huge thank you to all those who took part in last night’s PNEsleepout and to every single person who has donated!”.
An organisers' spokesman said: "We would like to thank each and every person who took part, donated or sent us messages of goodwill.
"The Big PNE Sleep Out has been months in the making and it's been humbling to see the city get behind such a great cause culminating in more than 300 people sleeping out at Deepdale last night.
"It was a fantastic effort by all those who bedded down and took part in what was a great event for the club and the city."
Donations are still being taken at the appeal's page at https://www.totalgiving.co.uk/appeal/ThePNEBIGSleepOut

CLASSIC CINEMA 101: JAMES FRAWLEY'S THE MUPPET MOVIE A review excerpt by Joe Barlow (c) Copyright 1999 - All Rights Reserved
STARRING: Charles Durning, Austin Pendleton, Scott Walker, and the voices of Jim Henson, Frank Oz, Jerry Nelson, Richard Hunt and Dave Goelz DIRECTOR: James Frawley WRITERS: Jack Burns and Jerry Juhl RELEASED: 1979
"A bear in his natural habitat... a Studebaker."  Well, in this state you'd probably get arrested... but that's okay, because you'd also get one of the most charming and endearing films to claw its way out of the 1970s.
The continuing appeal of The Muppet Movie is easy to understand after a viewing or two. It's a fun film, featuring some of cinema's loveliest melodies (both the musical score and its mesmerizing signature tune, "Rainbow Connection," were nominated for Oscars). But "fun" doesn't necessarily equate with "greatness," and it's not the only justification for the film's continued popularity. It touches a nerve with viewers. Its simple message ('Believe in yourself, and nothing is beyond your reach') is one we all want to believe... and in the hectic '90s, with weekly political scandals and perpetual conflict in the Middle East, we can all use some quality time with the Muppets and their values.
Kermit the Frog (voiced by the late Jim Henson) is a simple fellow. He lives in a swamp, and passes the time by singing songs and catching flies, yet somehow he feels unfulfilled. A passing fisherman (Dom DeLuise), who moonlights as a Hollywood agent, encourages the talented frog to consider a career in show business. Kermit is still hesitant, until the agent mentions that Kermit's talent could entertain millions of people. Wanting nothing more than to share his gifts with the world, Kermit sets off for Hollywood (by bicycle, no less! The sight is a visual marvel!) to seek his fortune. Along the way, he meets a number of other friends, all of whom have the same dream. The most significant of these are the amiable Fozzie Bear (voiced by Frank Oz), whose dream of being a stand-up comic is not at all hindered by the fact that his act isn't the least bit funny; the lovely Miss Piggy (Oz again), who falls hard for the dapper Kermit; and the strange turkey-like Gonzo (Dave Goelz) a plumber who dreams of being... well, a plumber. But having nothing better to do, he tags along for the ride.
 The Muppet Movie is not just another 90-minute kiddie flick, like so many of today's so-called family films. No, this one is the real thing: a warm comedy, with a message that actually says something significant to its audience; as such, it can be enjoyed by parents and kids alike.  Kids will laugh at Gonzo's physical stunts, while Mom and Dad will smile at the clever verbal jokes and visual gags that sail right over Junior's head (the piano player who looks just like Elton John, the recurring "hare krishna" motif, etc).

Thanks for participating in our study!


I am a Junior developer who is still learning but has a great wish to learn both back-end and front-end technologies.
Walk My Doggy Dog: Web application that helps users to connect through their dogs with persons that doesn't have a pet. App is made in PHP with Database and MVC.
Nba Stats App: This is Desktop application with CRUD functions, build in Java framework Hibernate and ORM technique. For GUI I used Java Swing toolkit. Data was fetched from available API services.
Yelp Camp: Web application made as part of learning process from Udemy Web course. Page is full responsive made with Node JS on back-end, EJS for rendering HTML, Mongo DB as database.
RGB Color Game: This was part of my code along project from Udemy course. Program is giving you a random rgb colors, and you have to guess wich one is right. Techniques that was used are: Vanilla JS, HTML, CSS and Boostrap and it is full responsive.
To-Do List: Is simple application for adding new todos. Application was made in HTML, CSS and jQuery. The page is full responsive, and new todos can be added with an enter key.
Innvention layout page: Simple layout made in HTML, CSS and Boostrap, page is full responsive.
On my current job at 4each I started learning and develop back-end servers in Python. Most of my programming is based on Python’s package AIOHTTP which is an HTTP client/server for asyncio. There for I was involved in several Projects, some of them was intern for our Firm and one of them was for Market.
Also I was working for inCheckin as Customer support. My job was to spot bugs and report them to development team and help users on there problems with application.
After the Java course I was intrigued by Web development. I took a Udemy Web developer bootcamp course. I started learning the fundamentals of HTML, CSS and JavaScript in combination with DOM manipulation, Boostrap, Jquery and Node JS on backend. Meanwhile, I enrolled in another web course. This time it was PHP at Edunova School of Informatics and Management which I also finished and build the Walk My Doggy Dog app with MYSQL database in MVC pattern, front-end of job was done with Semantic UI framework.
To the world of Java programming I was introduced by my friend. I started learning Java by myself, and then I realized that I need some better technical background so I took a course in Edunova School of Informatics and Management. The course lasted 6 months during which I successfully built my first application in the Hibernate framework using ORM technique, for front-end I used Swing GUI widget toolkit for Java. You can see the app on my Github profile .
Besides programming, I'm big sport fan. I often go to the Gym to workout. Also, I love to play Basketball and Table Tennis. I'm quite active in music, I like to write a Rap songs, and if occasion allows I perform my songs during social or Rap events. Down here is the video to see my latest work:
When I'm at home, I like to watch a Movies, TV Shows and read Books. My favorite book is the Bible. In my home Town Osijek I like to visit all kind of programming Conferences. Most of them are organized by the Osijek City Software. One of them is KulenDayz.

Adams College, the site of the original nerds movie, is now run by nerds. The Tri-Lambda fraternity is now number one and Alpha Beta, the very popular jock frat from the original film, is now the lowest of the frats. Robert Carradine, one of the original nerds, is now married to Julie Montgomery, jock Ted McGinley's girlfriend from the original, and working at the Computer Center at the College. Carradine refuses to admit that he was a nerd in his past and tries to hide it from himself now. His son Gregg Binkley is now going to Adams as a freshman and has joined the Tri-Lambda frat. McGinley gets put in as dean of the College, and since he hates nerds, starts a war against them. He has the Alpha Beta's start war against the Tri-Lambda's and causes a war between the jocks and the nerds.
REVENGE OF THE NERDS is one of the best films that I have ever seen.  I figured that REVENGE OF THE NERDS 3: THE NEXT GENERATION couldn't be as bad or worse than NERDS 2; I was wrong! It sucks! It is pathetically worse than awful! There is no way that I can recommend this film to anybody unless you are a couch potato that will watch anything; it is just a piece of garbage. On a scale of zero to five, I give NERDS 3 a zero.
The beginning of the problem lies in its story line, which was written by Steve Zacharias and Jeff Buhai. It starts out as a carbon copy of REVENGE OF THE NERDS, with two nerds in a car going to Adams College figuring out what time they will reach the campus (sound familiar?). At this point I was starting to ask myself, what have I gotten myself into? Now, here comes the *big* difference, the fraternities have changed their roles. Wow, I am thinking, a lot of work went into this film! Now the rest of the film is based on the war between the frats and Robert Carradine having to remember that he is a nerd (which you will remember he did at the end of the first film--boy is he forgetful!). The war, which is the high point of the film, isn't even very interesting. In the first film the war was great; the pigs at the party, the panty raid, the fake initiation, the pies. None of this stuff here, now we will resort to throwing people into pools and writing "nerd" onto the back of someone's head. Interesting stuff, huh? Now, during this war we are supposed to root for these nerds. In the first film there was no problem with that because they were cool people, but in this film they are just stupid. Then came along Booger, Curtis Armstrong, from REVENGE OF THE NERDS, just maybe my favorite character. Now I figured that the film will get going good. No chance, not even his role was well written. He had lost all of his charm. Now comes the big finale, and if you are still awake at this point you deserve a medal; if not, don't feel bad, you don't miss anything. I am glad that I rewatched REVENGE OF THE NERDS before viewing this film, that way I can remember a time when the nerds were funny and great to watch. Let's hope nobody gets the bright idea (?) to write a REVENGE OF THE NERDS 4: NERDS GETTING PUT DOWN AT THE WORKPLACE or something like that.
The acting, in nerds, jocks, nerd alumni, and jock alumni is horrible. Even the experienced (?) actors in the film (Robert Carradine, Ted McGinley, Curtis Armstrong, Julie Montgomery, and Morton Downey, Jr.) look pathetic. It doesn't look like anyone tried too hard to make this film look good. The new nerds are about as convincing as a banana pretending to be a pineapple. I don't know where they got these actors but they must not have tried too hard. When Morton Downey, Jr. came on the screen I figured that he would put a little effort into his role, but that was wishful thinking. Now, you would expect something from Robert Carradine, a two-time nerder. After he falls flat and Curtis Armstrong comes on I said now the movie has been saved. Now I am saying maybe Downey, Jr.'s acting isn't that bad after all! I have never thought much of Ted McGinley ("Married... with Children") but in this film he seems to be trying the hardest. Poor Julie Montgomery (billed as Julia Montgomery) the script doesn't give her a chance to do anything. Maybe she could have saved this film, but by this time I think it had sunk into the pit of no return.
The sets were rather good. They were the best part of the film I think. They looked realistic and that is good enough. The cinematography was okay, but nothing really spectacular. If you missed this film when it ran on Monday night on the Fox Television Network, don't feel sorry for yourself--consider yourself lucky. If you did watch it, I feel sorry for you, and if you stayed through the entire film, you are a very strong person. If you like the nerds, I suggest watching REVENGE OF THE NERDS again and forgetting about this one (and REVENGE OF THE NERDS 2: NERDS IN PARADISE for that matter).
Spoilers: only read on after seeing the film (or if you aren't going to bother seeing the film you may continue).
The biggest letdown in the film, at least for me, was the ending. First of all I could see it coming from a mile away and knew just about what was going to happen. That really spoiled the *BIG (??)* climax. Then when the old frat mates of Robert Carradine came in I was very disappointed for a few reasons. First of all Anthony Edwards, who played Carradine's best friend, didn't come back; instead they had a cheap imposter, Mike Greenwood, who looks nothing like Edwards. Second of all, the only frat mates who showed up were the homosexual, Larry B. Scott, the oriental, Brian Tochi, the little smart dude, Carradine's father, Cromwell, and the leader of the Tri-Lambda national office, Bernie Casey. What happened to all the other people? Did they think that we would just forget about them? Most likely I think that those actors, and Anthony Edwards, didn't want to have anything to do with this mess and listened to Nancy Reagan and "Just Said No."

IDIOTERNE (director: Lars von Trier; cast: Bodil Jørgensen (Karen), Jens Albinus (Stoffer), Anne Louise Hassing (Susanne), Troels Lyby (Henrik), Nikolaj Lie Kaas (Jeppe), Henrik Prip (Ped), Luis Mesonero (Miguel), Louise Mieritz (Josephine), Knud Romer Jorgensen (Axel), Katrine Michelsen (Nana), Anders Hove (Josephine's Father), 1998-Denmark)
This is the first film made under the label of Dogma, a Scandinavian film group inspired by the Danish director von Trier, which insists that their new manifesto on how to make films, be adhered to by those who make films under their label.
This dogma consists of improvised acting and hand-held camera work, among other dogmas the film must adhere to. It reminds me most of how Godard filmed during his Mao stage, but without the apparent overt political messages, as Godard's films during the late 60s were anti-film films, replete with diatribes against the bourgeoisie, which seemed filled with the director's hubris and self-congratulation on his political stance, that he was right and others wrong in their beliefs, and his rather tiresome political cliches, that seemed to be more opportunistic than spontaneous, even though every attempt was to make the film appear as if they were spontaneous.
Trier has a bunch of middle-class cult groupies living together in a rich private house that one of their relatives gave them, as the group members seem to be either in their late teens or their 20s, whose repulsive purpose is to freak out in public and sometimes do it when together in the privacy of their house.  These episodes of spassing give this film an odd look that is guaranteed to turn off a lot people and anger many, especially those who expect more conventional ways of looking at the problems young people face in society.
The theme of the movie is certainly obnoxious, it is very difficult to feel much of anything for these middle-class drop-outs, as we first encounter them in action in an elegant restaurant and watch them spasse, retardedly eating their food, under the direction of one of them (Susanne), who pretends to be their keeper, while one of them, Stoffer, grabs on to a lady (Karen), sitting alone, and refuses to let go of her. Karen seems to be responding kindly to the idiot, just like she didn't react with any ill emotion after being treated rather brusquely by the waiter when she told him she doesn't have much money and will be just ordering the salad.
They do another spassing in a Rockwood furniture factory, which was more stupid than humorous and belabored any point that was trying to be made about workers in a factory or about middle-class values, it was goofy in a way to watch them operate, as it seemed to be similar to the way that fraternities might find their inane initiation rites uplifting to their older members who already went through the initiation process to join the group, but to outsiders it would seem like they were seeing a bunch of spoiled children.
In another public spassing, Jeppe is left by the one playing his keeper (Stoffer), with a burly looking bunch of tattooed, beer guzzling biker types, who are asked to mind him for ten minutes, after they notice Jeppe staring at their tattoos, while the keeper goes to the other part of the bar. Again, it was not funny, but yet, it was curiously interesting, in a prurient kind of way to see what the interaction was going to be between these two groups of outcasts.
The most controversial part of the film is the sex orgy among the group members, acting as idiots, and actually seeming to copulate on camera (porno stars were used to do the sex), sort of giving the film a mock documentary feel to it, as the orgy members smear caviar all over their faces, and try to unbend from the middle-class environment they all came out of. The tenderest love making was between the teenager Josephine and the older Jeppe, who really seemed to be falling for each other, but could only do it under the cover of being idiots. Soon Josephine's father would embarrass her by coming to the group's home and removing her from the home.
The film moved into the gist of the filmmaker's message when Stoffer, the leader of the group, decided he would spin a bottle and whomever was chosen would have to spasse in front of family members or those they previously worked with. Axel and Henrik could not do it and thereby left the group.
  It is an act of courage. And it only matters when you can do it for real and not be using it to play a game.
Karen's story now unfolds; and, she turns out to be the one with the most dramatic thing to tell about her life. She volunteers to go back home to do her spassing with Susanne as her witness. We meet her family, who act cold towards her, asking her where she has been for the last two weeks, and wondering why she didn't go to her baby's funeral.  The trauma for her has reached a point of no return, and the very dangers of spassing or regressing back to one's childhood to find a way of dealing with a society you are antagonistic to, seems frought with extreme personal dangers, and the possiblity of a psychosis developing looms over all the young people's heads.
Trier has made his point. He has won me over. This very unusual personal film, that is very difficult to warm up to, that mocks what is conventionally thought of as right, by doing what is unconscionable and politically incorrect, becomes only too real and too sad to comprehend, as it is presented so as not to give us a way out in our perception of how to deal with the alienation the youngsters feel, as they seem to be left with only their naive hopes and disillusionments; and possibly, their emotional experiences that they can value. Their situation is not resolved. The film does not end with all loose ends tied up in a nice bow. We can't even be sure how long their commune life will continue, and how soon it is that they will find themselves out in the cold world, alone again, as misfits, where some of them will fit in without too much trouble but will be living a lie; and, where others will find it very difficult to go back to being middle-class, and will always be restless in such a society. But they tried something... and whether they reached their inner-self or not, something penetrated them, whether they are the better for this experience, is difficult to tell, but something significant to them did take place, just as we in the audience, whether we liked the film or not, something inside us was moved by what we saw taking place, causing us to react in a way we might not normally act when watching a film; and, in my way of thinking, that is great filmmaking.

Apache Hadoop 3.3.5 is an update to the Hadoop 3.3.x release branch.
Users are encouraged to read the full set of release notes. This page provides an overview of the major changes.
The abfs has a critical bug fix HADOOP-18546. ABFS. Disable purging list of in-progress reads in abfs stream close().
All users of the abfs connector in hadoop releases 3.3.2+ MUST either upgrade or disable prefetching by setting fs.azure.readaheadqueue.depth
to 0
Consult the parent JIRA HADOOP-18521 ABFS ReadBufferManager buffer sharing across concurrent HTTP requests for root cause analysis, details on what is affected, and mitigations.
HADOOP-18103. High performance vectored read API in Hadoop
The PositionedReadable
interface has now added an operation for Vectored IO (also known as Scatter/Gather IO):
void readVectored(List<? extends FileRange> ranges, IntFunction<ByteBuffer> allocate)
All the requested ranges will be retrieved into the supplied byte buffers -possibly asynchronously, possibly in parallel, with results potentially coming in out-of-order.
readFully()
calls, so delivers equivalent performance.readFully()
.Benchmarking of enhanced Apache ORC and Apache Parquet clients through file://
and s3a://
show significant improvements in query performance.

The new Intermediate Manifest Committer uses a manifest file to commit the work of successful task attempts, rather than renaming directories. Job commit is matter of reading all the manifests, creating the destination directories (parallelized) and renaming the files, again in parallel.
This is both fast and correct on Azure Storage and Google GCS, and should be used there instead of the classic v1/v2 file output committers.
It is also safe to use on HDFS, where it should be faster than the v1 committer. It is however optimized for cloud storage where list and rename operations are significantly slower; the benefits may be less.
More details are available in the manifest committer. documentation.
HDFS-16400, HDFS-16399, HDFS-16396, HDFS-16397, HDFS-16413, HDFS-16457.
A number of Datanode configuration options can be changed without having to restart the datanode. This makes it possible to tune deployment configurations without cluster-wide Datanode Restarts.
See DataNode.java for the list of dynamically reconfigurable attributes.
A lot of dependencies have been upgraded to address recent CVEs. Many of the CVEs were not actually exploitable through the Hadoop so much of this work is just due diligence. However applications which have all the library is on a class path may be vulnerable, and the ugprades should also reduce the number of false positives security scanners report.
We have not been able to upgrade every single dependency to the latest version there is. Some of those changes are fundamentally incompatible. If you have concerns about the state of a specific library, consult the Apache JIRA issue tracker to see if an issue has been filed, discussions have taken place about the library in question, and whether or not there is already a fix in the pipeline. Please don’t file new JIRAs about dependency-X.Y.Z having a CVE without searching for any existing issue first
As an open-source project, contributions in this area are always welcome, especially in testing the active branches, testing applications downstream of those branches and of whether updated dependencies trigger regressions.
Hadoop HDFS is a distributed filesystem allowing remote callers to read and write data.
Hadoop YARN is a distributed job submission/execution engine allowing remote callers to submit arbitrary work into the cluster.
Unless a Hadoop cluster is deployed with caller authentication with Kerberos, anyone with network access to the servers has unrestricted access to the data and the ability to run whatever code they want in the system.
In production, there are generally three deployment patterns which can, with care, keep data and computing resources private. 1. Physical cluster: configure Hadoop security, usually bonded to the enterprise Kerberos/Active Directory systems. Good. 1. Cloud: transient or persistent single or multiple user/tenant cluster with private VLAN and security. Good. Consider Apache Knox for managing remote access to the cluster. 1. Cloud: transient single user/tenant cluster with private VLAN and no security at all. Requires careful network configuration as this is the sole means of securing the cluster.. Consider Apache Knox for managing remote access to the cluster.
If you deploy a Hadoop cluster in-cloud without security, and without configuring a VLAN to restrict access to trusted users, you are implicitly sharing your data and computing resources with anyone with network access
If you do deploy an insecure cluster this way then port scanners will inevitably find it and submit crypto-mining jobs. If this happens to you, please do not report this as a CVE or security issue: it is utterly predictable. Secure your cluster if you want to remain exclusively your cluster.
Finally, if you are using Hadoop as a service deployed/managed by someone else, do determine what security their products offer and make sure it meets your requirements.
The Hadoop documentation includes the information you need to get started using Hadoop. Begin with the Single Node Setup which shows you how to set up a single-node Hadoop installation. Then move on to the Cluster Setup to learn how to set up a multi-node Hadoop installation.
Before deploying Hadoop in production, read Hadoop in Secure Mode, and follow its instructions to secure your cluster.


Accessing linux servers¶
If you have access to a remote Linux server this page covers how to connect to it remotely from your personal computer. Depending on the operating system (OS) and OS version of your personal computer, there are a few different ways of doing this. Note that this assumes that you are accessing your remote server directly and authenticating via password. If your institution or VPS provider uses intermediate authentication servers or key-based authentication, you should follow the instructions provided by them.
If you are attending the Theory and practice in metabarcoding for biodiversity workshop 7th - 13th January 2021, these instructions apply to you! The server IP address will be shared with you separately.
Connecting via SSH¶
We use SSH (Secure SHell) to send commands to the remote server and receive basic information in return, using the command line interface. When you log into a server for the first time it will ask you to reset your password. Once you have done so it will automatically log you out. You will then need to log back in using your new password.
Using terminal in MacOS or Linux¶
You can use the native terminal application available on any Mac or Linux machine. In Mac, if you haven’t used this before you can access it by using spotlight to search for “Terminal” or by navigating to the “Terminal” application using launchpad. On Linux starting a terminal using your GUI will vary depending on your distribution, but you can generally launch a terminal by pressing
.Once you have a terminal open, you then type an SSH command which looks like this:
ssh username@server_address
You will need to replace the username
in the above command with your username for the server. You’ll also need to replace the server_address
with the actual address of the server you are connecting to. If it is your first time connecting it will ask you if you trust the server, then will usually ask you for a password.
Using PuTTY in Windows¶
If you are running Windows you can use a program called PuTTY, an SSH client for windows. Once you have installed PuTTY, open it and type the server address in the field (see below screenshot). Then click . This will then bring up the login screen. Enter your credentials and click through any remaning prompts and it will give you access to the server.
Using Windows Subsystem for Linux¶
If you are running Windows 10, then an alternative to PuTTY is the Windows Subsystem for Linux (WSL), which allows you to effectively install a Linux operating system inside your Windows operating system. It is perhaps overkill to install a complete operating system simply to use SSH, but if you do decide to do this, once you have your Linux subsystem running you should follow the instructions above for using terminal in MacOS or Linux
Transferring files between local machine and server¶
There will be instances where you need to transfer files between your machine and a remote server. There are different ways to do this depending on your operating system and preferences.
Using the scp command in the terminal in Linux or MacOS¶
If you are running MacOS or Linux you can transfer files from local machine to server using the scp
command in the terminal.
An example of using scp
to transfer a file from your local machine to a server is below:
scp filename username@server_address:/path/
You type scp
followed by the file name (if you are not in the directory the file is in you will need to write the whole file path) followed by your username@server_address
followed by a colon then the path (from the root) to where you want the copy to go in the destination server. If you don’t know what the path is that you need to type in, remember, you can use pwd in the directory you want to send the file to and this will return the path of that directory.
To transfer from the server to your local machine you simply swap the order of your file paths i.e. server address and filepath then local file path.
Warning
The scp
command is always given from your local machines terminal.
Using FTP software¶
FTP software comes with the advantage of having a GUI so you can drag and drop files rather than typing out commands.
WinSCP (Windows)¶
Windows users can use an application called WinSCP to transfer files.
Follow the below steps to set up WinSCP:
- Change the file protocol drop down menu to SCP
- Type the address of the server you want to connect to in the Host Name field
- Enter your username and password for the server you want to connect to
- Click login
- Click through the remaining prompts
- You can now drag and drop files between your local machine and the server
FileZilla (Windows, MacOS, Linux)¶
Follow the steps below (see screenshot if unsure where to enter information):
- Open FileZilla
- Enter the server address in Host field
- Enter your username and password in the correct fields
- Enter 22 in the Port field
- Press quick connect
- Click through remaining prompts
- You can now drag and drop files between your local machine and the server


Views are the base concept of F.A.B. they work like a class that represent a concept and present the views and methods to implement it.
Each view is a Flask blueprint that will be created for you automatically by the framework. This is a simple but powerful concept. You will map your methods to routing points, and each method will be registered as a possible security permission if you want to.
So your methods will have automatic routing points much like Flask, but this time in a class. Additionally you can have granular security (method access security) that can be associated with a user’s role (take a look at Security for more detail).
The views documented on this chapter are the building blocks of F.A.B, but the juicy part is on the next chapter with ModelView, ChartView and others.
All views inherit from this class. it’s constructor will register your exposed urls on flask as a Blueprint, as well as all security permissions that need to be defined and protected.
You can use use this kind of view to implement your own custom pages, attached to a menu or linked from any point of your site.
Decorate your url routing methods with @expose. additionally add @has_access decorator to tell flask that this is a security protected method.
Using the Flask-AppBuilder-Skeleton (take a look at the Installation chapter). Edit views.py file and add:
from flask.ext.appbuilder import AppBuilder, expose, BaseView
from app import appbuilder
class MyView(BaseView):
route_base = "/myview"
@expose('/method1/<string:param1>')
def method1(self, param1):
# do something with param1
# and return it
return param1
@expose('/method2/<string:param1>')
def method2(self, param1):
# do something with param1
# and render it
param1 = 'Hello %s' % (param1)
return param1
appbuilder.add_view_no_menu(MyView())
You can find this example on:
look at the file app/views.py
This simple example will register your view with two routing urls on:
- /myview/method1/<string:param1>
- /myview/method2/<string:param1>
No menu will be created for this, no security permissions will be created also, if you want to enable detailed security access for your methods just add @has_access decorator to them.
Now run this example
$ python run.py
You can test your methods using the following url’s:
http://localhost:8080/myview/method1/john
http://localhost:8080/myview/method2/john
As you can see this methods are public, let’s change this example, edit views.py and change it to:
from flask.ext.appbuilder import AppBuilder, BaseView, expose, has_access
from app import appbuilder
class MyView(BaseView):
default_view = 'method1'
@expose('/method1/')
@has_access
def method1(self):
# do something with param1
# and return to previous page or index
return 'Hello'
@expose('/method2/<string:param1>')
@has_access
def method2(self, param1):
# do something with param1
# and render template with param
param1 = 'Goodbye %s' % (param1)
return param1
appbuilder.add_view(MyView, "Method1", category='My View')
appbuilder.add_link("Method2", href='/myview/method2/john', category='My View')
You can find this example on https://github.com/dpgaspar/Flask-AppBuilder/tree/master/examples/simpleview2
Use this decorator to expose views on your view classes.
| Parameters: |
|
|---|
Use this decorator to enable granular security permissions to your methods. Permissions will be associated to a role, and roles are associated to users.
By default the permission’s name is the methods name.
This will create the following menu
Notice that these methods will render simple pages not integrated with F.A.B’s look and feel. It’s easy to render your method’s response integrated with the app’s look and feel, for this you have to create your own template. under your projects directory and app folder create a folder named ‘templates’ inside it create a file name ‘method3.html’
1 - Develop your template (on your <PROJECT_NAME>/app/templates/method3.html):
{% extends "appbuilder/base.html" %}
{% block content %}
<h1>{{param1}}</h1>
{% endblock %}
2 - Add the following method on your MyView class:
@expose('/method3/<string:param1>')
@has_access
def method3(self, param1):
# do something with param1
# and render template with param
param1 = 'Goodbye %s' % (param1)
self.update_redirect()
return render_template('method3.html',
param1 = param1,
appbuilder=self.appbuilder)
3 - Create a menu link to your new method:
appbuilder.add_link("Method3", href='/myview/method3/john', category='My View')
As you can see you just have to extend “appbuilder/base.html” on your template and then override block content. You have many other blocks to override extending css includes, javascript, headers, tails etc... Next use Flask render_template to render your new template.
Note
Update redirect, on version 0.10.3, the redirect algorithm was reviewed, and uses session cookies to keep 5 records of navigation history, these are very usefull to redirect back, keeping url arguments, and improving UI experience. You must call self.update_redirect() to insert the current url into the navigation history. Sometimes you may want to skip the update, for example on form validation errors, so that the back operation won’t send you to the same form, prior to the validation error.
Inherit from this view to provide base processing for your customized form views.
In principle you will only need this kind of view to present forms that are not Database Model based, because when they do F.A.B. can automatically generate them and you can add or remove fields, as well as custom validators. For this you can use ModelView instead.
To create a custom form view, first define your WTF form fields, but inherit them from F.A.B. DynamicForm.
from flask.ext.wtf import Form, TextField, BooleanField, TextAreaField, PasswordField
from flask.ext.appbuilder.forms import DynamicForm
class MyForm(DynamicForm):
field1 = TextField(('Field1'),
description=('Your field number one!'),
validators = [Required()])
field2 = TextField(('Field2'),
description=('Your field number two!'))
Now define your form view to expose urls, create a menu entry, create security accesses, define pre and post processing.
Implement form_get and form_post to implement your form pre-processing and post-processing
from flask_appbuilder.views import SimpleFormView
from flask.ext.babelpkg import lazy_gettext as _
class MyFormView(SimpleFormView):
route_base = '/myform'
form = MyForm
redirect_url = '/myform'
form_title = 'This is my first form view'
message = 'My form submitted'
def form_post(self, form):
# process form
flash(as_unicode(self.message), 'info')
appbuilder.add_view(MyFormView, "My form View", href="/myform", icon="fa-group", label=_('My form View'),
category="My Forms", category_icon="fa-cogs")
Notice that this class derives from BaseView so all properties from the parent class can be overridden also. Notice also how label uses babel’s lazy_gettext as _(‘text’) function so that your menu items can be translated.
Most important Base Properties:
| form_title: | The title to be presented (this is mandatory) |
|---|---|
| form_columns: | The form column names to include |
| form: | Your form class (WTFORM) (this is mandatory) |


Embedding C++ Objects into QML with Context Properties
When loading a QML object into a C++ application, it can be useful to directly embed some C++ data that can be used from within the QML code. This makes it possible, for example, to invoke a C++ method on the embedded object, or use a C++ object instance as a data model for a QML view.
The ability to inject C++ data into a QML object is made possible by the QQmlContext class. This class exposes data to the context of a QML object so that the data can be referred to directly from within the scope of the QML code.
Setting a Simple Context Property
For example, here is a QML item that refers to a currentDateTime
value that does not exist in the current scope:
// MyItem.qml import QtQuick 2.0 Text { text: currentDateTime }
This currentDateTime
value can be set directly by the C++ application that loads the QML component, using QQmlContext::setContextProperty():
QQuickView view; view.rootContext()->setContextProperty("currentDateTime", QDateTime::currentDateTime()); view.setSource(QUrl::fromLocalFile("MyItem.qml")); view.show();
Note: Since all expressions evaluated in QML are evaluated in a particular context, if the context is modified, all bindings in that context will be re-evaluated. Thus, context properties should be used with care outside of application initialization, as this may lead to decreased application performance.
Setting an Object as a Context Property
Context properties can hold either QVariant or QObject* values. This means custom C++ objects can also be injected using this approach, and these objects can be modified and read directly in QML. Here, we modify the above example to embed a QObject instance instead of a QDateTime value, and the QML code invokes a method on the object instance:
| C++ | class ApplicationData : public QObject { Q_OBJECT public: Q_INVOKABLE QDateTime getCurrentDateTime() const { return QDateTime::currentDateTime(); } }; int main(int argc, char *argv[]) { QGuiApplication app(argc, argv); QQuickView view; ApplicationData data; view.rootContext()->setContextProperty("applicationData", &data); view.setSource(QUrl::fromLocalFile("MyItem.qml")); view.show(); return app.exec(); } |
| QML | // MyItem.qml import QtQuick 2.0 Text { text: applicationData.getCurrentDateTime() } |
(Note that date/time values returned from C++ to QML can be formatted through Qt.formatDateTime() and associated functions.)
If the QML item needs to receive signals from the context property, it can connect to them using the Connections type. For example, if ApplicationData
has a signal named dataChanged()
, this signal can be connected to using an onDataChanged
handler within a Connections object:
Text { text: applicationData.getCurrentDateTime() Connections { target: applicationData onDataChanged: console.log("The application data changed!") } }
Context properties can be useful for using C++ based data models in a QML view. See the following examples:
demonstrating the use of QStringList, QList<QObject*>-based models and QAbstractItemModel in QML views.
Also see the QQmlContext documentation for more information.

Using the information in the UML diagram above, suppose we execute the following Java statements:
Vehicle vehicle = new OilTanker(2500); vehicle.move();
which definition of move will be executed?
PeopleHauler is an interface, it does not contain an implementation of move
