VIDEO: Dynamics 365 for the .NET dev – Andrew Campey
When it comes to developing a website, you don’t use pure HTML and JavaScript – you
find frameworks to help. So why should your client CRM/ERP be any different?
In this talk, Andrew explains what exactly is Dynamics 365 and how we got here. Then
we explore how your existing .NET and JavaScript skills can help you create powerful
systems for your clients using Dynamics 365 as a base.

Workshop includes two days tuition with an experienced Angular developer,
full course material which will be updated as Angular is updated, full
source code for the three apps you will build for later reference and to
be used as best practice, and three months subscription to the
FirebootCamp Angular Slack channel.

.NET User Group: I have a container... now what? – presented by Thiago Passos
This is not the same container 101 talk you’ve seen a dozen times. The point of this
talk is how to ship a container to production, once you’ve built it.
We’ll containerize a .net core app, debug locally, set up continuous deployment, set
up a container cluster and deploy to it.

This was a whim-of-the-day type of experience. I've done this stuff once before, and only <5mg, so I kinda wanted something more intense.>
My friend mixed up approx. 40mg of Alpha-O Dimethyl Serotonin (as it is sometimes called) into a large container of Ice Tea, then named 'The Administrator'. I took a glass of it (about 5mg or less) then ate a capsule(another 10mg plus or minus 3mg) very soon after a breakfast of an organic egg omlet with mushrooms, green onions, and jalapeno jack cheese. So my day begins (at about 1pm)
Last time I snorted it, but I expected the effect to be slower since injesting it takes longer to get into the bloodstream. I encountered the usual queasy feeling after about an hour, but able to mentally combat the effect for another two hours (at which point I hurled, but not severely, since my breakfast was mostly digested at that point).
Ah, then the hyper-reality truly began.
First I got moving/shimmering shadows. Then I got outright strange visuals (the lemon slice in my icewater appeared to morph into various wicked Giger-esque shapes). I was somewhat nervous, hyper almost, with my legs shaking and all sorts of twitches going on. When the effect was fully on, it was unstoppable. Television was unbearable. I tried reading a bit of Neal Stephenson's Snow Crash, and it seemed to take forever as I pondered the meaning of every sentence construction.
Good think I had a buddy zinging with me, because I almost left to go to an ex-gf's BBQ party (before I was truly into outer space) but we decided that the unreality of the apartment was more than enough and the outside world was simply OUT OF THE QUESTION.
Music listened to: Well, I listen to some scary music and my zinging preferences verge on the 'psychotic paranoid' flavor, rather than the 'trippy happy fun time' mentality. We listened to Neurosis, God Speed You Black Emperor, Sleep, Electric Wizard, and other dark stuff. We took some scary digital camera pics of ourselves, heheh.
We also smoked some kind bud. That helped calm me down, especially after the distress of vomiting: we put in Built to Spill, and my partner remarks, 'This music makes me want to puke!', which I prompty did. Funny pun, right? Ah, never mind. The MJ didn't really change much, just calmed me down a bit.
On the wind down (occuring at approx T+8:00 hrs) we watched 6 straight hours of Pee-Wee's Playhouse on tape. The wind-down was marked by a tremendous headache, which asprin or ibuprofin could cure (though a lot was needed). Like all AMT's, MAO inhibitors should be avoided, such as beer, bananas, and hmm, other things I can't recall. (we didn't have any complaints).
Wow, good conversations, great visuals. The one thing I can say is that I was always aware of how wide my third was open. I even managed to cook a zucchini stir-fry but how I managed to do that without harming myself is unbelievable.  At one point my roomate came in and tried talking to us and there was that strange psychological dilemna of 'should we tell her or not?' but in the end we told her and it was still cool (she was drunk).
So like other experience files I've read, I had no dreams when I went to sleep (about 5am), and felt pretty zombie-ish the next day (serotonin levels drained).
Damn, I hope this stuff is never scheduled, but I still will only embark on such a journey once every 3 months or so. Good times should be had in moderation.

Tourist tries clicking selfie during Venice floods, falls into water. Viral video has 5 lakh views
A hilarious video of a tourist shot during the Venice floods has gone viral on social media.
A hilarious video of a tourist in Venice - shot during the floods in the Italian city - has gone crazy viral on social media. Since the beginning of November, Venice battled difficult conditions as the city was hit by its highest tide in more than 50 years.
The four-second clip has been shared on Twitter by StanceGrounded and has garnered over five lakh views so far. Of course, because it is funny. The clip features a man wading through a flooded area in Venice with a selfie stick and guess what happened next?
Well, you need to watch this yourself:
The video has garnered over 26,000 likes while netizens posted funny lines in the comments section. "While in Venice, be like scuba diver," a user said while another added, "Scoot over! We are all coming along."
Internet cannot stop laughing as well:
Venice, a World Heritage Site, was flooded on November 12 by a tidal surge of 187 cm, the highest level since 1966, when a 194 cm tide was recorded, news agency IANS reports. Within the next four days, Venice's St Mark's Square was completely drowned in water.


Twitch Studio Beta Now Available For All Game Streamers
by Shane McGlaunTwitch launched a closed beta for Twitch Studio a few months ago. The beta was a new streaming app, and Twitch says that "tons" of streamers that signed up to try it. After taking all the feedback from the streamers who tried Twitch Studio beta, the beta is now open to everyone who wants to try it out.
Twitch Studio Beta is available for anyone on Windows 7 or newer operating system. To talk streamers into trying the open beta for the new Studio, Twitch is running down some of the best features of the beta software. The setup is guided, making it easy to detect your mic, webcam, monitor resolution, bitrate, and more to help the stream look and sound great.
The beta offers customizable templates that give streamers just starting layouts and overlays to help personalize the look of the stream. Integrated alerts make it easy for new streamers to monitor and interact with their community using the built-in alerts, activity feed, and Twitch chat. There are some known bugs with the beta right now.
Twitch says that to capture a game, app, or window in Twitch Studio, users need to add a screen share or main screen share layer. In some cases, what users are trying to capture might not work. Instances of the capture failure issue have been seen on Google Chrome, Firefox, and other browsers. Destiny 2 and other games that block the capture injection process, and Vulkan-powered games like Wolfenstein are known to cause issues with the beta. Twitch says a workaround is to capture the monitor in these instances.
Supported capture cards in the beta include:
Elgato cards:
- HD 60S
- HD 60 S Plus
- HD 60 Pro
- HD 4K Pro
Avermedia cards:
- Live Gamer Extreme 2 (GC551)
- Live Gamer Ultra (GC553)
- Live Gamer Portable 2 Plus (GC513)
- Live Gamer Mini (GC311)
- Live Gamer HD 2 (GC570)
- Live Gamer 4K (GC573A)
The last time we talked about Twitch was when Ninja left for Mixer. Only five days after Ninja joined Mixer, he had a million subscribers.


static
.
A static
inner class does not keep an implicit reference to its enclosing instance.
This prevents a common cause of memory leaks and uses less memory per instance of the class.
Example:
public class Outer {
class Inner { // not static
public void foo() {
bar("x");
}
private void bar(String string) {}
}
}
After the quick-fix is applied:
public class Outer {
static class Inner {
public void foo() {
bar("x");
}
private void bar(String string) {}
}
}


This app makes you able to maintain your todos up-to-date. Multiple users can access and edit the todos in parallel*.
Parallel: users have to share the same local storage (be on same browser)
For the sake of the demo, all the API calls are mocked. In order to be as realistic as possible they are delayed and subject to failures. Any data that needs to be persisted such as Authentication tokens or todos are stored within the local storage of the browser in use.
The token used and stored to keep the user connected to the API can be revoked by updating the value of window.validToken in the console or by clicking .


Using a VPN is one of the best ways to hide what you’re doing online from your ISP and other users on your network, or make sure your traffic is secure on a public network. It’s also great to hide your IP address or bypass content filtering on a website or on your network.
The use of the BitTorrent protocol (used by Popcorn Time) for unauthorized sharing of copyrighted content (movies and tv shows) has led to a variety of novel legal issues. While the technology and related platforms are perfectly legal, law enforcement and prosecutorial agencies worldwide are developing new tactics and increasingly pursuing ways to address this avenue of infringement.

Contains the configuration for discover groups, connector, connection factory, queues and topics to a remote ActiveMQ Artemis server:
A connector defines how to connect to a remote ActiveMQ Artemis server.
For more information about connectors, see the Connectors documentation.
A discovery group defines how connector information is received from a broadcast endpoint, for example, a UDP multicast address or JGroup channel.
A discovery group maintains a list of connectors, one for each broadcast by a different server. As it receives broadcasts on the broadcast endpoint from a particular server, it updates its entry in the list for that server. If it has not received a broadcast from a particular server for a length of time it will remove that server’s entry from its list.
By default, the ${build.shortName} messaging subsystem provides the InVmConnectionFactory
and
RemoteConnectionFactory
connection factories, as well as the
activemq-ra
pooled connection factory.
Pooled connection factories allow you to configure the inbound and outbound connectors of the remote ActiveMQ Artemis resource adapter. For more information on configuring a pooled-connection-factory to connect to a remote ActiveMQ Artemis server, see Using the Integrated Resource Adapter for Remote Connections.
The queues and topics that exists in the remote ActiveMQ Artemis server.

why do people put locks
on the links of chain link fences?
I want to open my window
and hear the crash of a billion snowflakes
I want to feel the circle of your arms
and the slip and slide of your skin on mine
in warm water, somewhere in the Caribbean
and doze in a hammock
with a lemonade in hand
I want to pretend to be Hemmingway
and sit in a cafe, sipping a Cuba Libre
I want to write I love you
on a napkin
and slip it your way
see your face
hope your eyes light up
like the way they do when I dance with you
I want to dance with you
in a salsa club
pulsing music and your body leading mine
to tumble into bed with you
and wake up in France, with creamy brie on my tongue,
the smell of french bread in the air,
the crackle of the crust as I break you off a piece.
I want to lay in the grass
of a field somewhere
a fleecy blanket keeping the cold out
and the heat in
as we look at the stars
and grip the blades, entwining our fingers
and holding on
so we don’t fly away
except with each other.

Hello, my name is Elizabeth Saunders, a student currently studying at Confederation College in the IMD (Interactive Media Developement) program, studying towards an Ontario College Advanced Diploma.
I've had a few opportunities to have my artwork up in the Thunder Bay Art Gallery. As well as a couple opportunities to compete in the Skills Ontario Competition for Architectural Technology and Design, and the Graphic Design Studio Production Scopes. A few of my images found in the Photography section have also been published on Pixabay. Also, opportunities to create logo designs for organizations such as, Thunder Bay District 5-Pin Association.
On this portfolio you will find my love of graphic design, photography, and illustration within the many projects done for clients and personal use. Click Below to view in Portfolio.

Google Chrome's 'Close Other Tabs' Option Is Back!
by Lawrence AbramsGoogle just released Google Chrome 78.0.3904.108 and with it is the return of the 'Close other tabs' feature that Google mistakenly took out in previous versions.
With the release of Chrome 78, Google removed the 'New tab', 'Close other tabs', 'Reopen closed tab', and 'Bookmark all tabs' context-menu options as they stated these functions could be performed with other methods or were not used enough.
For people, like myself, who used 'Close other tabs' throughout the day, Google recommended that users drag the tab they want to keep over to the first tab and then right-click on it and select 'Close tabs to the right'.
I have to say, after using this method for a few weeks, their suggested method is just annoying and makes Chrome less usable rather than better.
The good news is that 'Close other tabs' is now back in the latest version of Chrome 78 released today.
Google, now that it's back, don't touch it again!

How it works? It is simple. Just download library from Github and link zinjs.js into your source code.
It is free? Yes, it's completely free. You can use, redistribuate or change library even in commercial projects. ZinJS is distribuated under new BSD licence. You must only keep copyright marks inside source code of library.
What I can do with library? The only limit is your imagination. You can create website based on "zooming" of content or rotating or something else...
Documentation We will add documentation on this site as soon as possible. In a meanwhile you can follow us on Github. Github also provide bug report form.
Prototype Please note that ZinJS is still prototype so it's still under development. Some features may be altered.

This site is inspired from the poem 'The Tripping Tadpole' (Rin Rin Renacuajo) by Colombian poet Rafael Pombo. I first came across this story when I was about 6 years old. I found the book laying on the street on my way home from school. Out of curiosity I picked up the book and skimmed through the pages. The books was beautifully illustrated with hand-drawn pictures and watercolored lanscapes. I wasn't much of a reader back then, but I was so amazed by the illustrations I decided perhaps the book was worth reading.
The story is about a young tadpole named Rinrin. In the story, Rinrin goes out with a suit and time even though, his mom tells him not to leave the house. He ignores her and strolls away. Later he finds his friend the Mouse who invites him to visit Lady Rat for some feast and dancing. Rinrin accepts and they both go tripping to Lady Rat's. She welcomes them in and both Rinrin and Mouse joing her in the feast.
After sometime of partying, a cat shows up and snaches both Mouse and Lady Rat. To Rinrin's dismay, the cat eats both his friends in one gulp. Rinrin darts out the door and runs (or hops) as fast as he can. Unfortunately, he ends up jumping into a duck's mouth and is swallowed immediately, leaving his mom sad and lonely. Good times!


STDBUF(1) User Commands STDBUF(1) NAME stdbuf - Run COMMAND, with modified buffering operations for its standard streams. SYNOPSIS stdbuf OPTION... COMMAND DESCRIPTION Run COMMAND, with modified buffering operations for its standard streams. Mandatory arguments to long options are mandatory for short options too. -i, --input=MODE adjust standard input stream buffering -o, --output=MODE adjust standard output stream buffering -e, --error=MODE adjust standard error stream buffering --help display this help and exit --version output version information and exit If MODE is `L' the corresponding stream will be line buffered. This option is invalid with standard input. If MODE is `0' the corresponding stream will be unbuffered. Otherwise MODE is a number which may be followed by one of the following: KB 1000, K 1024, MB 1000*1000, M 1024*1024, and so on for G, T, P, E, Z, Y. In this case the corresponding stream will be fully buffered with the buffer size set to MODE bytes. NOTE: If COMMAND adjusts the buffering of its standard streams (`tee' does for e.g.) then that will override corresponding settings changed by `stdbuf'. Also some filters (like `dd' and `cat' etc.) don't use streams for I/O, and are thus unaffected by `stdbuf' settings. EXAMPLES tail -f access.log | stdbuf -oL cut -d ' ' -f1 | uniq This will immedidately display unique entries from access.log BUGS On GLIBC platforms, specifying a buffer size, i.e. using fully buffered mode will result in undefined operation.

Creating a conference hub
The relationship between geometry and architectural design are described and discussed along some examples. Geometry is the fundamental science of forms and their order. Geometric figures, forms and transformations build the material of architectural design. In the history of architecture geometric rules based on the ideas of proportions and symmetries formed fixed tools for architectural design. The relationship between geometry and architectural design are described.

Traveler | Food Enthusiast | Global Citizen
I am a full stack web developer who places great value on effort and teamwork. I have a positive attitude and enjoy motivating others to do their best. My background in science and international education has equipped me with the critical thinking and analytical skills useful for problem-solving. After immersing myself in web development, I am very excited to continue to build new things and work on more web projects. Outside of programming, I have interest in forensic science (especially anthropology), as well as cultural awareness, global citizenship, and international education. My dream career is a position that will allow me to make meaningful contributions in any of these areas through my web development skills, small or large.

$array, |
|
|
|
$column, |
|
|
|
$index = null |
|

Non-PHP 5.5 implementation of array_column
- Parameters
-
| array | $array | |
| string | $column | |
| null | $index | |
- Returns
- array
◆ arrayFilterKeys()
| static arrayFilterKeys |
( |
array |
$data, |
|
|
array |
$keys, |
|
|
|
$checkIsSet = false |
|
) |
| |
|
static |
Returns a version of the input $data that contains only the array keys defined in $keys
Example: arrayFilterKeys(['a' => 1, 'b' => 2, 'c' => 3), ['b', 'c']) Returns: ['b' => 2, 'c' => 3]
- Parameters
-
- Returns
- array $data
◆ mapDiff()
| static mapDiff |
( |
array |
$array1, |
|
|
array |
$array2 |
|
) |
| |
|
static |
Recursively returns the difference between two associative arrays. Returns any key that is in array 1 but not 2; returns any value (from array 1) where the value is different in array 2.
- Parameters
-
| array | $array1 | |
| array | $array2 | |
- Returns
- array
◆ mapMerge()
| static mapMerge |
( |
array |
$first, |
|
|
array |
$second |
|
) |
| |
|
static |
This is a simplified version of a function similar to array_merge_recursive. It is designed to recursively merge associative arrays (maps). If each array shares a key, that key is recursed and the child keys are merged.
This function does not handle merging of non-associative arrays (numeric keys) as a special case.
More than 2 arguments may be passed if desired.
- Parameters
-
- Returns
- array
◆ parseQueryString()
| static parseQueryString |
( |
|
$string | ) |
|
|
static |
Parses a query string (x=y&a=b&c[]=d) into a structured array format.
Note that this can handle very long query strings, but it has problems if there are conflicting elements that split the "chunks" that are made internally. Workaround this using distinct keys for each input whenever possible.
- Parameters
-
- Returns
- array

Ranveer Singh and Deepika Padukone return from Amritsar with their families
by Vedanshi PathakRanveer Singh and Deepika Padukone celebrated their first wedding anniversary in the most special way. The couple got married last year on November 14 according to South Indian customs and on November 15 according to Sindhi rituals at lake Como in Italy.
To celebrate their first anniversary this year, the couple took off with their families to seek blessings at the Venkateshwara Temple in Tirupati on November 14 and then visited the Golden Temple in Amritsar. The pictures of the couple from their spiritual visits have been floating online and created a mega buzz among their fans. Today, they were spotted returning to Mumbai after their mini trip.
The couple was snapped at the Mumbai airport with their families, who happily posed for pictures for the paparazzi waiting to catch a glimpse of them. Ranveer and Deepika looked phenomenal as they stepped out in heavy ethnic attires that they had worn for their visit to the Golden Temple earlier this morning. We wish the couple all the love as they complete one year of married bliss. Scroll through their latest pictures.

I have an acquaintance whose infant son has landed his first dramatic role. He is two and a half, and will be playing one of the Three Wise Men in his nursery nativity play. The part calls for him to deliver the line “I have myrrh”.
He has been rehearsing with admirable diligence. It is, I think, a credit to his acting skills that, while one rarely, if ever, encounters myrrh in 21st century Britain, he gives a compelling performance and one truly believes that, yes, this small child does indeed have myrrh. And he has been able to inhabit fully the character of the Wise Man without having to ask the director “what's my motivation?”. He comes to it naturally.
As Sir Laurence Olivier said to Dustin Hoffman on the set of Marathon Man, when the latter expressed surprise that Olivier did not employ “the Method”, “It's called acting, dear boy”.


Charles RobertDarwin was born in Shrewsbury, Shropshire, England on 12 February 1809 at his family home, the Mount. He was the fifth of six children of wealthy society doctor and financier Robert Darwin , and Susannah Darwin (née Wedgwood). He was the grandson of Erasmus Darwin on his father’s side, and of Josiah Wedgwood on his mother’s side. Both families were largely Unitarian, though the Wedgwoods were adopting Anglicanism. Robert Darwin, himself quietly a freethinker, made a nod toward convention by having baby Charles baptised in the Anglican Church. Nonetheless, Charles and his siblings attended the Unitarian chapel with their mother, and in 1817, Charles joined the day school, run by its preacher. In July of that year, when Charles was eight years old, his mother died. From September 1818, he joined his older brother Erasmus attending the nearby Anglican Shrewsbury School as a boarder.
Darwin spent the summer of 1825 as an apprentice doctor, helping his father treat the poor of Shropshire. In the autumn, he went with Erasmus to the University of Edinburgh to study medicine, but was revolted by the brutality of surgery and neglected his medical studies. He learned taxidermy from John Edmonstone, a freed black slave who told him exciting tales of the South American rainforest. This experience gave him evidence that “Negroes and Europeans” were closely related despite superficial differences in appearance.


Horner claims Albon is blameless in FP1 crash in Brazil
by Nicolás Quarles van UffordAfter another crash for Alexander Albon since his promotion to Aston Martin Red Bull Racing, team principal Christian Horner has come out to defend his rookie driver, claiming the Thai was not to blame for his FP1 crash in Brazil due to the track conditions.
Interlagos was still wet once running in FP1 started, and as the track dried up, Albon was one of the first drivers to brave the track on slick tyres. Driving on the soft compound, the C3, the 24-year-old ran wide on the damp track and became a passenger as he went through the grass and into the barrier.
A low-speed impact, but enough to break the suspension on his RB15, although Red Bull mechanics fixed the car in time for FP2, in which he finished ninth.
When quizzed about his driver's incident, Horner took responsibility as he thinks it was too early to go out on slick tyres in hindsight.
"I think today you can't put on Alex's account," the Brit told Autosport.
"Maybe we were a little bit too optimistic getting out there trying to get him laps in on a track that was still pretty damp in the middle sector.
"And Max he had a moment at Turn 1 and Turn 2, there were other cars as well running wide," he said in reference to Max Verstappen also running wide but just about managing to keep his car out of the wall.
I don't think today's [incident], we can blame that on Alex.
"He's had a few little incidents this year, thankfully they've all been on Fridays and Saturday mornings, and when it's come to it in qualifying and the race he's absolutely delivered."

The special operators block and return-from work together to provide a structured, lexical, non-local exit facility. At any point lexically contained within forms, return-from can be used with the given name to return control and values from the block form, except when an intervening block with the same name has been established, in which case the outer block is shadowed by the inner one.
The block named name has lexical scope and dynamic extent.

Below are some typical questions student have about CSE131.
If your question isn't answered here, please ask!
-
How is the lecture-free version of this course different
from a traditional version of this course?
-
Follow the above links.
- Why should I study computer science at Washington University?
-
- Computer science is a discipline that has roots in mathematics,
logic, philosophy, and engineering. Computer science and computation are
an integral aspect of almost all areas of study. The issues looming largest
for our society today (health,
environment, and energy) all have interesting and challenging applications
within computer science.
-
The study of computer science teaches
and fosters a logical approach to solving problems, and students
in computer science say the discipline teaches them to think
in a different way.
- Computer science lends itself well to studies abroad, with students
traveling to Israel, England, Australia, Scotland, and New Zealand.
- Our students intern, coop, or are employed at the foremost
established companies, the most exciting start-ups, and all points in
between.
The future is bright for those who study computer science, with all of our
graduates receiving strong offers of employment.
- Our department is well situated to get you started, having received
funding from the National Science Foundation in recognition of our pioneering
approach to pedagogy. Our prerequisite chain is short, so that you can
soon take courses that most suit your interests. Our curricula are
flexible, with most of our students earning majors or minors in other
disciplines of interest along with their computer science major or minor.
- Our department eagerly attracts and involves undergraduates in research.
In this way,
as you learn the basics of our field, you also contribute to solving its
open problems.
- How is this course different from a typical lecture class?
- A 3 unit lecture class typically consists of 3 hours of lecture per week. This
course is quite different, in that it uses
active learning for most of the material you will study.
Each week generally consists of the following:
- A single lecture (or online videos and exercises) to introduce the topic(s) studied.
- A studio session in which you work collaboratively with
other students to extend and enhance the material covered in lecture
- A lab/recitation/quiz session in which you work on lab assignments,
review the current week's material, and take a quiz on the previous week's
material.
Thus, you spend 1.5 hours in lecture, but 3 hours working in much smaller
groups to learn the materail for this course.
- If I am struggling with the course material, how do I get help?
- We recognize that the material you are studying is nontrivial. It
is challenging and at times you will need help.
We have a myriad of resources at your disposal:
- Weekly recitation sections
- Your TAs hold office hours
- Your instructor holds office hours
- Tutors can be arranged through your school.
Contact Assistant Dean Chris Ramsay
to arrange for a tutor
- How do I earn participation credit for this course?
- There are exercises included with each module, interspersed between
the video segments. You earn participation credit by completing those exercises
as best you can.
- What is the difference between CSE131 and CSE131R?
- CSE131 is the standard course, and CSE131R is an optional 1-unit pass/fail
seminar associated with CSE131 offered in the fall semester.
This seminar
is intended for students who may intend studies in computer science: a
major, a minor, or a second major from another school.
Credit is given for CSE131R based on attendance.
The seminar features:
- Guest lectures by
Computer Science and Engineering faculty about their research.
- Further exploration of certain topics covered in the main course.
- I cannot access my SVN repository
- First, make sure you have a repository. If you added the class after the first day
of classes, then ask the instructor to make sure you have a repository set up. The information
on how to access your repository is included with Lab 0.
The most common problem is that you are not authenticating correctly with the server.
-
For your username, be sure to supply your WUSTL key name but spell it completely in lower case.
For example, if you are used to typing John.Doe as your user name, type it in
as john.doe.
-
For your password, be sure to supply the password you use for logging into WebSTAC, and spell
it just as you type it in to WebSTAC.
For example, if your password is NobodyWillGuessThis, then type in
NobodyWillGuessThis.
- I have installed eclipse on my Windows 7 computer. However, when I follow the instructions
to set up subversive (SVN), the relevant menus don't seem to be there.
- For reasons we have not yet fathomed, this problem occurs only when your eclipse files are
in the special program files folder in Windows 7. So don't put the files there,
just put them on your desktop (the folder will be called eclipse, and the thing you
click to run eclipse is inside that folder).
In other words, re-download the eclipse project from the website, but this time unzip the files
to your desktop.
- I am on the waiting list for CSE131 or for the lab section I need.
Will I be able to take the course?
- Almost certainly!
Be sure to attend class on the first day.
In the past, we have been able to accommodate everyone from the waiting
list.
- I in one lab/studio section and need to switch to another.
What should I do?
- Stay registered where you are, to make sure you keep your seat in
the course. Then come to the lab section that works for you and we will
have room.
Feel free to do this whenever necessary.
- Do I need any computer science background to succeed in CSE131?
- No. The only prerequisite for this course is that you be
comfortable with algebra and geometry at the high school level.
No programming background is required. We start from the beginning. However,
the course is demanding and does move rather quickly. If you're looking
for an easy course, this isn't it.
- I have some programming experience. Will I be bored in
CSE131?
- Most high school computer science courses cover programming, but not computer science as a discipline.
In other words, you may have learned the nuts and bolts, but the background
and theory are likely to be missing.
However, we do not want you to waste your time! If you have had an AP
course in computer science, or some other substantive experience, please
see the instructor. We have a placement exam you can take to see if you should
place out of CSE131.
- How much time should I expect to spend on CSE131?
- CSE131 emphasises learning by doing. Most of your time outside of
class will be spent on lab assignments.
You will spend very little
time reading, since everything you need to know will be covered in
lecture, studio, or in the lab assignments. Since CSE131 is a 3 unit course,
you should expect to spend about 10 hours per week on average, including
time spent watching videos, doing assignemnts, and attending studios.
Some weeks will
require more time, some will require less.
- Is there a textbook for CSE131?
- Yes. Although previous instances of our course were offered without
a textbook, we have found it easier to teach the course consistently by
using a textbook. Also, students have felt more secure with the material
by having a textbook handy.
In addition to the text,
on-line materials will be provided or referenced.
The textbook in use for this semester is listed on the home page.
- Do I need a CEC account for CSE131?
- No. You should be able to log into our lab computers using your
standard WebSTAC authentication. Moreover, you are able and encouraged to
use your own computer
by following the installation instructions:
- Do I need to buy a computer for CSE131?
- No. You do not need to own a computer to take this course,
but most students do own their own computer and you are encouraged to do
so as well.
You are welcome to use our lab computers whether you have your own
computer or not.
Labs are reserved for classes at certain times, and open for
general use at other times. See the
schedule posted by the lab door for details.
- If I want to buy a computer, what should I buy?
-
This is a matter of personal preference, and you should discuss your options
with the instructor, other students, and with whoever will be paying for
your computer.
- Where should I store my work?
-
No matter which computer you use, your work is managed
by subversion, which saves your files in a very safe place
(meaning it is frequently backed up by someone other than you)
when you commit them. This will allow you to work from any place that has
an Internet connection.
- I'm having trouble with my computer.
Where can I get help?
- Try the EIT/CEC help desk in Lopata Hall. If your computer is not working,
use a lab computer until yours is fixed so that you don't fall behind in
your work.
- I have accommodation on timed exams and quizzes. How do I arrange
to take these?
- Please present your accommodation documentation to the instructor
the first week of class. The in-term exams will have extra time for you
to complete the work. You will be allowed extra time for recitation quizzes as well.
No extra time is allowed for labs, except as provided by the
late lab policy.
- I have a conflict with one of my exams in this class.
What should I do?
- Most likely, this class is larger than your other class, and the exam
dates are set well in advance of the semester so that there
are no conflicts. However, other classes sometimes move
their exam dates in a way that causes a conflict.
In such cases, you must take up this issue with your other class.
If there are other circumstances that arise that cause a conflict for you,
please contact the instructor as far in adavnce as possible.
- What is CSE 501N? How is it different from 131?
-
The courses are identical in all aspects of the work you do: labs, studios,
exams, and quizzes. Some students take this course as preparation for
graduate studies in computer science, or to assist in their graduate studies in other
disciplines. Such students enroll in this course at the graduate level,
using CSE 501N.
- Eclipse says my repository is locked, what do I do?
-
-
In the package explorer, right- (control-) click on your main project name,
- choose Team →
- choose Cleanup
- When trying to commit or update I have conflicts, what do I do?
-
-
First, commit any work that you can:
- In the package explorer, right- (control-) click on your main project name,
- choose Team →
- choose Commit
- In the window you are shown, uncheck any entries marked conflicting
- Proceed with the commit
If the commit does not work, seek help from the instructor before
doing any of the following steps.
- Then, let's try to clear up the conflicts
- choose Team →
- choose Synchronize with Repository
- In the resulting window, you see the conflicts.
Documentation for resolving conflicts can be found
here.
- My favorite choices are:
- Override and update: this indicates that you want to go with
the version of the file that is on the server, and replace your version with that one. Your local copy will be lost forever, so be certain this is what
you want if you choose this option.
- Override and commit: this indicates that you want your version
of the file
to win. Your local version then replaced the one at the server. You can
always retrieve any previously committed version from the server.
- When done, return to the Java view and commit your work as usual.
- If in doubt, ask the TAs or instructor.

An ongoing experiential primer in web dev.
Reference W3 Schools and Google for just about anything.
Element = opening tag + content + closing tag
HTML Attributes = belong to tags
e.g. <tag attribute="value">contents</tag>
One great example would be a link to another site like this using the href attribute or an image using the src attribute:
Just don't forget your alt tag; it will make someone's life better when viewing your page.
Or using iframe to embed a video like this:
No content, so no closing tag
e.g. Images  or Break

Inline = Just end the line and wrap to the next
e.g. Break

Block = Create invisible box that can have height and width
e.g. Paragraph

Hold other elements
e.g. Span  (inline) or Div
 (block)
Add ordered, unordered, or HTML lists for bullets, numbers/alpha, or menus; use CSS for styling to create tabbed menus or use alternative images for bullet points.
Lists can be nested; here,the nested list is part of a list item from the parent list:

Parent List

First Item

Second Item

Third Item with a nested list

Nested List

Nested First Item

Nested Second Item

Fourth Item

Simplified with HTML5, HTML documents follow this basic structure (but not needed for codepen...codepen just needs the typical  content):
<!DOCTYPE HTML> = doctype
 = opening html tag
 = metadata like js and css
<title> = title for browser window
 = content of doc
Everything is boxes; so when exploring a webpage, break it down into boxes that become divs and other elements
HTML is the structure, CSS is the style, and JS is the interactive
Create an HTML comment that is for people but not computers with
Use corresponding indentation to create an easy-to-follow, easy-to-modify, and easy-to-apply-CSS/JS webpage
Use the class attribute to provide labeling to your divs; this will provide additional benefits when working with CSS and JS
You can inspect elements of a page using Developer Tools in Chrome
From the style panel in Developer Tools, you can (temporarily) alter the CSS for specific elements
Developer tools also includes a cool feature for resizing the page to meet different form factors for responsive design testing!
CSS is a powerful tool for creating an experience around your HTML structure. It's important to follow a paradigm within your styling (this is where style guides are important) and to leverage classes to avoid unnecessary repetition as much as possible. Flexbox only works on modern browser versions but creates a simple way to stack divs next to each other.
tag name {
attribute:value
}
You can do the same with classes for less repetition; instead of the tag name, use .class-name
Use attribute:value pairs (each on their own line for clarity) to apply the rules to the tag or class specified (the selector)
In CSS, code comments begin with /* and end with */
Example of separating structure from presentation: replace emphasis and bold HTML tags with span tags that have an emphasis or bold class assigned; then in the CSS, define the rules for those classes to add italics via font-style or bold via font-weight
Browsers use default style sheets for common elements like h1/h2/h3/etc. so you can use those tags and apply style/spacing to your content without the need for additional CSS
Box sizing
Each HTML element has 4 components: margin, border, padding, content.
To adjust sizing:
Box positioning
Divs are block (vs. inline) elements so they automaticaly take the full width of the page.
Adding the rule "display: flex" to the parent div element in CSS allows them to sit next to each other (if the child elements have been given a size less than the automatic 100%). This uses an approach called flexbox; allowable in modern browsers only.
Always verify your HTML and your CSS to check for errors or informational tips.
Computers are the universal machine (sound familiar, Alan Turing?) but only have a few routines themselves. They need programs to provide instructions for what to do and in what order.
Computer languages created to prevent:
<Non-Terminal> --> Replacement
Start with non-terminals, keep replacing until you hit all terminals through derivation
Recursive Grammar
What is a variable? A variable is a named representation of some expression; it defines "a" is "b". Variables can be used in their own assignment (e.g. days = days-1...when constantly re-evaluated, you get a countdown).
What does it mean to assign a value to a variable? Applying the definition of "b" to "a" is the assignment; similar to CSS classes or IDs, it allows for definitions to be made up front (where they can be easily changed in 1 location) but applied in multiple easy-to-understand uses throughout the code.
What is the difference between math and programming for the "=" sign? Algebraically, "=" means equality; in programming, "=" means assignment like a left-pointing arrow (take the expression value on the right side and use that anywhere you see the name on the left).
Udacity has a python interpreter available here
An index finds a portion of a string (e.g. the 2nd character)...the first character is at position 0
string[n] returns the nth character of the string
An index subsequence can find multiple characters within a string...a few examples:
string[n1:n2] starts at the n1th character and evaluates to just before the n2nd character
string[:] starts at the beginning character and evaluates to the final character
string[:-2] starts at the beginning character and evaluates to just before the 2nd to last character
Find method used to find strings in strings
string1.find(string2) finds string2 within string1 (precisely, it finds the position [number] within string1 where the first occurence of string2 exists unless you pass a position parameter)
def function_name(arguments):
body
return output
print function_name(parameters_to_use)
Define the function, then use the function
Some variables, like strings and integers are immutable, meaning their value cannot be altered by any function
Just like with arithematic statements, we can compare values to return Boolean results (True or False)
Comparisons include:
We can compare integers to integers, strings to strings, and in some cases, integers to strings...a few examples:
print 1 < 2 #returns TRUE
print 5 > 20 #returns FALSE
print 5 == 5 #returns TRUE
print "hello" == "hello" #returns TRUE
print 5 == '5' #returns FALSE
print 7 != 10 #returns TRUE
"if" allows our code to make decisions on what to do based on the result of expressions tested
if <test_expression>:
block_to_evaluate_when_result_true
next_statement_to_evaluate_regardless_of_result
This function takes the value of a number and returns the absolute value (if the number is negative, make it positive; either way, then return the number):
def absolute(x):
if x < 0:
x = -x
return x
But it's better to close your if statements using else, to explicitly define what to do when the if result is false; this function returns the bigger of two numbers:
def bigger(x,y):
if x > y:
return x
else:
return y
The Boolean values True and False are not strings, so no quotes needed:
return True
OR provides logical evaluation of two expressions to true or false but only evaluates what is needed to find true:
Like an IF statement, the test expression is evaluated, and if true, the block is evaluated. However, with an IF statement, once the block has been evaluated, the code moves to the next statement outside of the IF. With WHILE, once the block has been evaluated, the code moves back to the test expression and repeats. The WHILE statement only ends (sending the code to the next statement) if the test expression evaluates to false.
Use break to jump out of a while loop; leverage an if statement where, when true, the code to run is break which immediately moves to the code following the while loop.
In this example, if the IF statement evaluates to true, hitting the break, then the code jumps out of the loop (skipping the second "some code") and moves straight to the "some code after the while loop":
while (something):
some code
if (something):
break
some code
some code after the while loop
Strings are sequences of characters; Lists are sequences of anything (characters, numbers, even other lists)
You can use an index on a list to return particular elements; you can also use multiple indexes if your list contains lists, for example:
beatles[3][0] will return the 1st element of the 4th element of a list named "beatles"
Mutation - changing an element's values
Aliasing - referencing the same object through multiple assignments
If the list [1,2,3] is assigned to p, and p is assigned to q, then changing the 2nd element of p (p[1] = 5), makes both p and q have the assignment of [1,5,3].
Append - method (like .find) that mutates a list to include a new element at the end (that new element could be a reference to another list)
Python has special syntax that operates like .append shown as +=, e.g. mylist += [3] is the same as mylist.append(3) but is not the same as mylist.append([3])
mylist = [1,2]
mylist += [3] ---> [1,2,3]
mylist.append(3) ---> [1,2,3]
mylist.append([3]) ---> [1,2,[3]]
mylist + [3] ---> [1,2,3]
list.append(new_element)
Addition - operation like concatenation ("+") that creates a new list from other existing lists
list + list
Length - procedure operation (len) that determines the number of outer elements within a list (can also be used to count characters in a string)
len(list)
For loops iterate through each element in a given list, jumping out of the loop when all elements have been evaluated; each element in the list is assigned to the name variable below for each loop iteration:
for <name> in <list>:
<block>
Index method invoked on a list provided a given value returns the first position of that value in the list (if the value is in the list; otherwise, error):
list.index(value)
In operator returns true/false to determine if a value is in a list:
<value> in <list> will return True or False
Not In operator returns true/false to determine if a value is not in a list:
<value> not in <list> will return True or False

If Statements
Loops (helpful tutorials)
Functions (helpful tutorials)
Abstraction allows us to focus on the programs we want to write by leveraging other components already created (such as the Python Standard Library)
For example, I don't need to write a program to find the current time, I can just use time.ctime() after declaring import time, without having to even know how this standard function works.
Customizing your turtle
A class, like a class in CSS, groups items together. Here, a class can be initialized (brad = turtle.Turtle()) creating space in memory for a new instance. Then whatever has been assigned the class can call the functions within that class (.shape, .color, and so on).
You can use a FOR loop for i in range(1,5): that can run the drawing commands a certain number of times (4, in this example); a safer alternative to WHILE loops with counters since you can never get into an infinite loop scenario.
External Python packages listing
Think of classes as blueprints, containing basic information, and objects as examples or instances of that blueprint
Simple Definitions
A class is a grouping of functions that can be accessed collectively. An instance of a class is a defined object given the ability to call the functions of the class; multiple instances can exist simultaneously. Here's the benefit of OOP: you can take this class and create millions of individual instances (objects) that co-exist without interferring with each other.
Libraries are collections of modules that can be imported within your code; amplifies the tools at your disposal without having to write the code or even understand how it's working (like when we import "webbrowser" or "media" and can then call the classes within to create instances).
Following the aforementioned style guide, classes should follow a proper case naming convention (e.g. class Movie)
Class Variables are variables that apply to all instances of a class (like valid movie ratings across a list of movies)
If class variables are constants (i.e. not changing frequently), then use ALL CAPS in the naming convention
Inheritance is the act of child classes using variables or methods from a parent class
Method overriding occurs when a class explicitly defines some method that it also would have inherited from it's parent (the methods would have the same name in both classes)

Private-jet terminal blocked by climate activists at Geneva airport
by REUTERSClimate-change activists blocked Geneva airport's private jet terminal on Saturday in protest against what they said is an absurd form of transport.
Geneva is a hub for the private jets of the rich and powerful who either live nearby or travel to the lakeside city for its private banks, auction houses, hospitals and U.N. offices.
Dozens of activists sat in front of the small terminal building, linking arms in peaceful protest. Police cordoned off the area.
"We have blocked the private-jet terminal to defend the principle of climate and social justice," Extinction Rebellion's Geneva chapter said on Facebook. "This means of transport is completely absurd."
Extinction Rebellion was founded in Britain last year, inspiring waves of disruptive actions around the world to call for rapid cuts in carbon emissions and the repair of collapsing ecosystems.
"Our politicians are only taking small measures, to satisfy citizens, while at the same time saying that we have to make efforts, that if everyone one makes efforts, we can fight against climate change," said a protester who gave his name only as Nicolas, 27, a student.
"Making only people responsible can't work when you have private jets companies like this one, behind us, which keeps on emitting tons and tons of CO2 in the atmosphere," he said.
The company that operates the terminal said Saturday's protest had caused few complications as traffic was light but it was not clear how much longer the demonstration would last.


In this assessment, you will create:
Then, you will write a SQL file that will insert data into the tables.
Then, you will write a SQL file that contains a SQL statement that joins the tables together.
There's an image in the "images" directory that shows the picture of the data model.
There are mocha tests that determine if it can connect to the database with the specified user name, password, and database name. Then, it checks the tables to make sure that they have the structure specified.
npm install
.Create a database user named "merchant_app" with the password "bhKx5P6V". There is no file for this. Just do it for your local installation of PostgreSQL. The tests assume that it exists.
Create a database named "merchant_development" with the owner "merchant_app". There is no file for this. Just do it for your local installation of PostgreSQL. The tests assume that it exists.
Create the following tables in the database. Write the CREATE TABLE statements in the files that match the table name. For example, in the "create-users-table.sql", write the CREATE TABLE statement for the "users" table.
The tests will drop all of the tables run the table creation for you automatically.
Do these in order.
The "PK, NOT NULL" specification means it should be a primary key. The "FK" specification means it should be a foreign key. All columns will be "NOT NULL".
The "users" table | Column name | Column type | Constraints | |————-|————–|————–| | id | SERIAL | PK, NOT NULL | | full_name | VARCHAR(255) | NOT NULL | | created_at | TIMESTAMP | NOT NULL |
The "merchant_types" table
| Column name | Column type | Constraints |
|---|---|---|
| id | SERIAL | PK, NOT NULL |
| type | VARCHAR(20) | NOT NULL |
| Column name | Column type | Constraints |
|---|---|---|
| id | SERIAL | PK, NOT NULL |
| name | VARCHAR(100) | NOT NULL |
| continent_name | VARCHAR(20) | NOT NULL |
| Column name | Column type | Constraints |
|---|---|---|
| id | SERIAL | PK, NOT NULL |
| merchant_name | VARCHAR(255) | NOT NULL |
| country_id | INTEGER | FK, NOT NULL |
| created_at | TIMESTAMP | NOT NULL |
| admin_id | INTEGER | FK (to users id), NOT NULL |
| merchant_type_id | INTEGER | FK, NOT NULL |
You can run just the table tests to make sure your CREATEs are correct.
npm test – -g "when created"
Create INSERT statements for the four tables in each of the four files provided for you. Here is the data that you should include. Don't insert more data than what is here. Otherwise, the tests in the next section will fail.
This is not going to be tested. The SQL that you write will. You'll need this data for your SQL statements to work correctly.
| full_name | created_at |
|---|---|
| 'Zaphod Beeblebrox' | CURRENT_TIMESTAMP |
| 'Blart Versenwald III' ** | CURRENT_TIMESTAMP |
**
| type |
|---|
| 'Retail' |
| 'Wholesale' |
| name | continent_name |
|---|---|
| 'Brazil' | 'South America' |
| 'China' | 'Asia' |
| 'USA' | 'North America' |
In this section, the foreign keys are not specified by numbers. They show, in parentheses, the unique value from a row in the seed data, above. Depending on how you insert them, they may have different ids. Figure out what the id will be for it and put that in your SQL INSERT statement for "merchants".
For example, if you insert "Brazil" first in your insert-countries-data.sql file, then you will use 1 as the country_id for (Brazil) below.
The tests will drop and recreate the tables on each test, so the values should be stable.
| merchant_name | country_id | created_at | admin_id | merchant_type_id |
|---|---|---|---|---|
| 'Zingo' | (Brazil) | CURRENT_TIMESTAMP | (Zaphod) | (Retail) |
| 'Widgets International' | (China) | CURRENT_TIMESTAMP | (Blart) | (Wholesale) |
| 'Snglrify' | (USA) | CURRENT_TIMESTAMP | (Zaphod) | (Retail) |
| 'Better Products 4 U' | (USA) | CURRENT_TIMESTAMP | (Zaphod) | (Wholesale) |
Write a SQL statement in joined-data-query.sql that returns the following data by JOINing the tables:
Order the records on the merchant_name column.
The result should look like this.
| full_name | type | name | merchant_name |
|---|---|---|---|
| Zaphod Beeblebrox | Wholesale | USA | Better Products 4 U |
| Zaphod Beeblebrox | Retail | USA | Snglrify |
| Blart Versenwald III | Wholesale | China | Widgets International |
| Zaphod Beeblebrox | Retail | Brazil | Zingo |


Getting Started¶
Installing from PyPI or Conda¶
Open3D Python packages are distributed via PyPI and Conda.
Supported Python versions:
2.7
3.5
3.6
Supported operating systems:
Ubuntu (tested on 16.04, should work on other modern versions)
MacOS
Windows 10 (32-bit and 64-bit)
PyPI¶
pip install open3d
Note: In general, we recommend using a
virtual environment for
containerization. Otherwise, depending on the configurations, pip3
may be
needed for Python 3, or the --user
option may need to be used to avoid
permission issues. For example:
pip3 install open3d
# or
pip install --user open3d
# or
python3 -m pip install --user open3d
Conda¶
conda install -c open3d-admin open3d
Note: Open3D prebuilt binaries for Conda (Anaconda/Miniconda) can be found at
open3d. Currently, the open3d
package is distributed under the open3d-admin
channel. To setup Conda,
please see the official documentations.
Try it¶
Now, try importing Open3D.
python -c "import open3d"
If this works, congratulations, now Open3D has been successfully installed!
Running Open3D tutorials¶
A complete set of Python tutorials and testing data will also be copied to
demonstrate the usage of Open3D Python interface.
For example, tutorial Basic/rgbd_redwood.py
can be run with:
cd lib/Tutorial/Basic
python rgbd_redwood.py
It reads a pair of RGB-D images and visualizes them.
It then transforms the RGB-D image into a point cloud, then renders the point cloud using Open3D visualizer.
The Python code is quite straightforward, and the detailed explanation can be found in Redwood dataset. You may further experiment with different tutorials or check out the complete tutorial list in the Tutorial page.
Note
Open3D’s Python tutorial utilizes some external packages: numpy
,
matplotlib
, opencv-python
. OpenCV is only used for reconstruction
system. Please read util/scripts/install-deps-python.sh for installing these
packages.
