Autocomplete Widgetversion added: 1.8
Description: Autocomplete enables users to quickly find and select from a pre-populated list of values as they type, leveraging searching and filtering.
By giving an Autocomplete field focus or entering something into it, the plugin starts searching for entries that match and displays a list of values to choose from. By entering more characters, the user can filter down the list to better matches.
This can be used to choose previously selected values, such as entering tags for articles or entering email addresses from an address book. Autocomplete can also be used to populate associated information, such as entering a city name and getting the zip code.
You can pull data in from a local or remote source: Local is good
for small data sets, e.g., an address book with 50 entries; remote
is necessary for big data sets, such as a database with hundreds or
millions of entries to select from. To find out more about
customizing the data soure, see the documentation for the source
option.
Keyboard interaction
When the menu is open, the following key commands are available:
- UP - Move focus to the previous item. If on first item, move focus to the input. If on the input, move focus to last item.
- DOWN - Move focus to the next item. If on last item, move focus to the input. If on the input, move focus to the first item.
- ESCAPE - Close the menu.
- ENTER - Select the currently focused item and close the menu.
- TAB - Select the currently focused item, close the menu, and move focus to the next focusable element.
- PAGE UP/DOWN - Scroll through a page of items (based on height of menu). It's generally a bad idea to display so many items that users need to page..
When the menu is closed, the following key commands are available:
- UP/DOWN - Open the menu, if the
minLength
has been met.
Additional Notes:
- This widget requires some functional CSS, otherwise it won't work. If you build a custom theme, use the widget's specific CSS file as a starting point.

sourceType: Array or String or Function( Object request, Function response( Object data ) )
none; must be specified
Independent of the variant you use, the label is always treated
as text. If you want the label to be treated as html you can use
Scott
González' html extension. The demos all focus on different
variations of the
source
option - look for one that matches your use case, and check out
the code.
- Array: An array can be used for local
data. There are two supported formats:
- An array of strings:
[ "Choice1", "Choice2" ]
- An array of objects with
label
andvalue
properties:[ { label: "Choice1", value: "value1" }, ... ]
value
properties, the value will also be used as the label. - An array of strings:
- String: When a string is used, the
Autocomplete plugin expects that string to point to a URL
resource that will return JSON data. It can be on the same host
or on a different one (must provide JSONP). The Autocomplete
plugin does not filter the results, instead a query string is
added with a
term
field, which the server-side script should use for filtering the results. For example, if thesource
option is set to"http://example.com"
and the user typesfoo
, a GET request would be made tohttp://example.com?term=foo
. The data itself can be in the same format as the local data described above. - Function: The third variation, a
callback, provides the most flexibility and can be used to
connect any data source to Autocomplete. The callback gets two
arguments:
- A
request
object, with a singleterm
property, which refers to the value currently in the text input. For example, if the user enters"new yo"
in a city field, the Autocomplete term will equal"new yo"
. - A
response
callback, which expects a single argument: the data to suggest to the user. This data should be filtered based on the provided term, and can be in any of the formats described above for simple local data. It's important when providing a custom source callback to handle errors during the request. You must always call theresponse
callback even if you encounter an error. This ensures that the widget always has the correct state.
When filtering data locally, you can make use of the built-in
$.ui.autocomplete.escapeRegex
function. It'll take a single string argument and escape all regex characters, making the result safe to pass tonew RegExp()

The DALI workshop is a one-day, by-invitation, workshop dedicated to exploring needs of scientific communities for new languages and infrastructures for the scalable analysis of data. Languages such as R, Matlab, Python and Julia, are of particular interest but the scope of discussions includes all languages and infrastructures used for data analytics.
The workshop will consist of a number of short talks and discussions. Part of the output of the workshop will be a recommendation to the National Science Foundation for funding an institute to support the development of open infrastructures for scalable data analytics. The workshop will bring together practitioners and language developers from academia and industry.
Funded by the NSF Software Infrastructure for Sustained Innovation (SI2) program.

About
AuthorPal is an app principally built for Google Chrome that is designed to aid in creating projects like a book outline or blog/etc by using an object-oriented design philosophy. It is a computer-managed system designed to allow you to easily build/plan your creative work and quickly access the information you need.
Getting Started
By clicking 'Menu' and then 'create file' you can create a project based on various templates. Files save automatically every time you leave a text element. Currently text can be added using either Markdown or raw html. Note: Color scheme for AuthorPal can be changed by going to Menu: Preferences.
Saving/Uploading Files
All your work is automatically saved to localStorage every 15 seconds. LocalStorage is sort of like a cookie (but different) and can potentially be deleted when you delete your cache. To save a backup copy go to File (top left) and click Download. This allows you to save a file containing all your work (not just the file you're working on) to either your downloads folder or a folder of your choice if you right-click. The data is in json format and can be edited in any text editor/ide capable of working with json. This file can be re-uploaded to Authorpal with File > Upload if you lose your work for some reason (may overwrite data already there if names match).
Using Markdown
https://help.github.com/articles/basic-writing-and-formatting-syntax/ has a nice explanation of how to use markdown. Note: use of headers is not recommended.
Not a fan of markdown? html code for bold/etc also works, or prefix the name of the textblock you're working with with a '*' and it will turn off markdown rendering for that textblock.


An interactive introduction to ecological networks
When we eat fish, what impact does that have on the environment?
With other meats like beef and pork, we tend to focus on things like the greenhouse gas emissions from cow farts and the added nutrients in their surroundings due to animal waste, which are all really important.
But unlike cows, pigs, and chickens, fish aren't all raised in ranches. Around 50% of the world's fish supply comes from fisheries taking these fish out of the oceans and the seas for us to consume. In the ocean, fish interact with other species, like whales, and sharks, and other fish. As such, there's an additional factor we need to think about: How does the removal of fish affect the ecosystem it was taken from?
As mentioned before, fish might interact with many different species, and with all these connections it's hard to know where to begin. One way we can attempt to start, and what we're going to do here, is think about the "who-eats-who" relationships. And to do so, we're going to construct an ecological network.
As seen here, in our ecological network, each species is represented as a point in space, a node. In this case, we've got sea urchins represented.
This node represents how many species there are with the solid red inner circle, and how many there can be with the outer circle.
Try adding and removing sea urchins from our node above. (Don't worry too much about the 'play' and 'reset' buttons.)
So we can add or remove sea urchins, but currently that's not really super interesting.
Fortunately, there are some species that interact with sea urchins, like sea otters which eat urchins. Let's add a new node for sea otters as well as a link connecting the two species to represent their interaction.
Now try adding and removing mass from the urchin population and see what happens. (Press 'play' to see the interaction in action!)
Here are a few things to note:
With nodes and links, we can begin to understand how removing fish affects the ecosystem.
Let's add yet another node to the current network, this time what urchin eat: kelp.
Try adding or removing mass from the kelp population, and see how the urchin and sea otter communities change. Not much, right? Now try adding or removing mass from the sea otter population. Note how much larger the change is here.
Why did populations react differently when we removed the same amount from both populations?
You likely guessed it, but it's because otters eat many urchins and urchins eat many kelp. So when some otters get removed, that many more urchins can eat that much more kelp. And in kelp forests, this can mean the difference between a lush kelp forest filled with all sorts of fish or an urchin barren of nothing but sea urchins.
This amplification of effects, from otter to urchin to kelp, is what's known as a trophic cascade. Changes in the population high up in a network can have cascading effects that ripple down to the bottom, ultimately changing the environment and the species composition of the entire ecosystem. These cascades are often really undesirable because they can cause catastrophic changes to an ecosystem and alter it until it's unrecognizable, even if what we directly affect is really small.
Other than changing kelp forests, what else can trophic cascades have an effect on? In this case, we'll see how changing populations high up in a network can change the diversity of the ecosystem.
In the tide pools, organisms like mussels, barnacles, and limpets that attach themselves to the rocks compete for space against one another. Mussels can often beat out its competitors for space on the rocks, but are also the primary food item for the sea star Pisaster ochraceus.
In our network currently, mussels take up more space than the other species. Can you make the species composition more balanced by only adjusting sea star populations?
As you might have done yourself, by increasing sea star populations, mussels get eaten more often, allowing more space for the other 3 species to grow. On the other hand, eradicating sea stars would cause mussel populations to shoot up and prevent other species from taking hold.
This is a huge problem facing coastal ecosystems across North America due to sea star wasting disease, which has decimated sea star populations in recent years. This severe decline in sea star populations thus not only means loss of sea stars, but likely also severe reductions of other organisms in the tide-pool that are outcompeted by mussels.
So we've seen the potential for trophic cascades. But do all networks necessarily have cascades? And is there any way we can take species higher up in a network without unintentionally triggering one?
We can look to coral reefs as an indication. In coral reefs, there is a constant battle between coral and algae. Herbivorous fish like parrotfish and rabbitfish can help corals by consuming algae before it covers the surface. However, we humans also eat a lot of reef fish.
Try exterminating different species and see how much the coral population changes.
If we exterminate just a single species of fish, we can see that the coral population doesn't change too much. It might be hard to track, but this may be due to the other 2 untouched fish species, which are able to fill in for the exterminated species.
But, as we continue to remove more fish species, note that the remaining fish species are less and less capable of filling in, with coral populations getting smaller and smaller.
On the other hand, changing human demand immediately has a cascading effect.
The difference between these fish species and humans is that the fish, being more diverse, have more opportunities for picking up the slack of others. If one species goes extinct, the others can still keep algae populations low.
So that's it. Not all species removed have equal impact. Consuming fish has lower impact on the ecosystem when these fish are:
Of course, there are other factors we ignored here. A lot, actually. Networks can change based on behavior or population dynamics. Different fish take different resources to fish or raise. Fishing by dragging nets at the bottom of the seafloor can damage fish's homes and their ability to find mates. We're taking small fish by the boatload, which could have just as much impact as fishing for larger predators.
But as an oversimplified rule of thumb:
To have the least impact on ecosystems, and to prevent unwanted trophic cascades, eat small, eat low.

Documentation / Features / Draftable
Overview
Draftable is a feature that uses a second set of tables to hold a 'draft' version of the object graph separately from the 'live'. Typically the draft objects are edited and go through an approval process before being published.
To implement this feature all @Draftable and @DraftElement beans have a second draft table that closely resembles the live table but commonly will have additional columns to support an approval workflow for publishing.
Publishing is a function that takes underlying rows from the draft tables and copies them to the matching live table. In this way the application can easily maintain a 'draft' version and 'live' version of the entities.
Mapping
ENTITY MAPPING
@Draftable
@Draftable
is an annotation put on entity beans that should support draftable
features.
The @Draftable annotation put on 'top level' (or root level) entity beans and @DraftableElement is put on related child entity beans which are considered part of the same graph.
Publishing a @Draftable
bean will publish the 'top level' @Draftable entity beans
along with any of its related child @DraftableElement beans.
@DraftableElement
@DraftableElement
is an annotation put on entity beans that are part of a draftable
object graph but not 'top level' beans. The publish() and draftRestore() functions act on a draftable
bean and all it's associated draftableElement beans as a single unit (published/restored as a unit).
PROPERTY MAPPING
@DraftOnly
@DraftOnly
is an annotation put on properties that exist on the draft table only
- these properties do not exist on the associated live table. For example, annotation properties
that are on the draft to support approval workflow (workflow status, when publish timestamp etc).
@DraftDirty
@DraftDirty
is an annotation that can be put on a boolean property of a @Draftable entity bean.
This property only exists on the draft table and it's value is automatically set to true when the draft
bean is saved and automatically set to false when the draft bean is published. The property is expected
to be used to identify (query) draft beans that should be published.
Currently a change to a @DraftableElement does not set the dirty flag on the 'owning' @Draftable bean and instead this would need to be done manually in this case if required.
@DraftReset
@DraftReset
is an annotation that can be put on a property of a @Draftable entity bean.
The value of this property is automatically set to null on the draft bean after it has been published.
For example, the property is could contain comments or timestamp values related to the approval workflow
(and after a bean is publish these are 'reset' to null on the draft bean).
Query As Draft
A normal Query builds the object graph from the 'live' tables. You can specify the query to run
asDraft()
and then it will build the object graph using the draft tables. This can be
used to PREVIEW
the currently editing state of the object graphs.

Note: Any asDraft
query does not use the L2 cache (Only queries for live beans can use L2 cache).
Publish
Publish
is the function that takes the values from draft object graph and applies them
to the matching live object graph. The publish function cascades from a top level @Draftable entity bean
to any related @DraftableElement entity beans.
@OneToMany
A @OneToMany
relationship to a @DraftableElement effectively has save and delete cascade
turned on automatically. The cascade save/delete is used internally to publish the object graph.
@ManyToMany
A @ManyToMany
relationship to a @Draftable bean effectively has save and delete cascade
turned on automatically to maintain the relationship.
Database database = DB.getDefault();
// publish a single bean (from draft to live)
// returning the 'live' bean
Document liveDoc = database.publish(Document.class, docId);
// publish using a query
Query<Link> pubQuery = database.find(Link.class)
.where().idIn(ids)
.order().asc("id");
// publish returning the resulting 'live' beans
List<Link> pubList = database.publish(pubQuery);
Draft Restore
DraftRestore
is the function that takes the values from the live object graph and applies them
back to the matching draft object graph. You can consider it the opposite of a publish().
Database database = DB.getDefault();
// Restore a single draft bean
database.draftRestore(Document.class, docId);
Query<Document> restoreQuery = database.find(Document.class)
.where().idIn(ids)
.order().asc("id");
// Restore all the beans matching a query
database.draftRestore(restoreQuery);
Example Application
An example application is available at example-draftable .
L2 Cache
Only live beans and queries can use the L2 cache. Similarly only save/delete of live beans invalidate parts of the L2 cache. All queries for draft beans do not use the L2 cache and save/delete of draft beans do not invalidate any part of the L2 cache.


BRASERO(1) BRASERO(1) NAME brasero - Simple and easy to use CD/DVD burning application for the Gnome Desktop SYNOPSIS brasero [options] [uri] [uri] ... DESCRIPTION This manual page documents briefly the brasero command. Brasero is a disc burning application. It is designed to be simple and easy to use. It allows to create data CD/DVD, audio CD, to copy CD/DVD and to burn images. It has some nices features, such as a song, image and video previewer. It can also search for files (thanks to beagle) and dis‐ play a playlist and its contents. OPTIONS This program follows the usual GNU command line syntax, with long options starting with two dashes (`-'). A summary of options is included below. For a complete description, see the Info files. -p, --project=PROJECT Open the specified project. -a, --audio Open an empty audio project. -d, --data Open an empty data project. -c, --copy=PATH Copy a disc. -j, --cover=PATH Cover to use. -o, --video Open a video project adding the URIs given on the command line. -i, --image=PATH Uri of an image file or a cue file to be burnt (autodetected). -e, --empty Force brasero to display the project selection page. -b, --blank Open the blank disc dialog. -k, --check Open the check disc dialog. -n, --ncb Open a data project with the contents of burn:/// URI. -r, --burn-and-remove-project=PATH Burn the specified project and REMOVE it. -g, --debug Display debug statements on stdout. --display=DISPLAY X display to use. -?, --help Show summary of options. -v, --version Show version of program. AUTHOR Brasero manual page was written by Philippe Rouquier <philippero@liberty‐ surf.fr> and Luis Medinas<EMAIL_ADDRESS>GNOME January 11, 2009 BRASERO(1)


Runs the LEAN Report Creator in a Docker container using the quantconnect/lean Docker image.
By default, this command generates a report of the most recent backtest.
This behavior can be overridden by using --backtest-results <path>
and providing the path to the backtest results JSON file.
If --live-results <path>
is also given, the generated report will contain both the backtest and the live results.
The --strategy-name
, --strategy-version
, and --strategy-description
options can be used to set the name, version, and description that are shown in the report.
The name and version are shown in the top-right corner of each page, while the description is shown on the top of the first page.
These fields are blank by default.
When the given backtest results are stored in a project directory or one of its subdirectories, the default name is the name of the project directory and the default description is the description in the project's config.json file.
By default, the official LEAN engine image is used.
You can override this using the --image <value>
option.
Alternatively, you can set the default engine image for all commands using lean config set engine-image <value>
.
The image is pulled before running the report creator if it doesn't exist locally yet or if you pass the --update
flag.


Specify the path to the Tricentis CI test execution configuration XML file. The test configuration file includes more details about which items you would like to execute.
If you use this setting, leave the TestEvents setting of this page empty. Otherwise, this build step fails.

Traffic woes: SPC to convene meet
At Nandavanam on Nov. 24
by Staff ReporterState Police Chief (SPC) Loknath Behera will convene a meeting of stakeholders on November 24 to address the traffic woes of the State capital. The discussion, which will be held at the Armed Reserve Police camp in Nandavanam, will involve various cross-sections including representatives of residents associations, drivers, school authorities and traders.
The Kerala Police have requested those intending to attend the meeting to send in their questions in advance by mailing them to<EMAIL_ADDRESS>within 5 p.m. on November 21.
The meeting will explore various options to effectively regulate vehicular flow including imposing restrictions on lorries traversing the arterial roads of the city during peak hours, shifting bus stops that are located close to traffic signals, and steps to ensure lane discipline among motorists.


This section documents specific pairs of implementations for which interoperability has been demonstrated. Each row represents a producer and each column a consumer. If a pairing has at least one recorded instance of interoperation, and no recorded failures, then it is marked as a "Pass". If a pairing also has at least one recorded instance that uses a security configuration identified in WoT Security Best Practices then it is marked as "Secure". However, if such a pairing has any reported failures, no matter how many other successful pairings it has, including secure pairings, it is marked as a "Fail". Note that since implementations refer to code bases that may be used for many services or devices, each successful pairing reported may in practice correspond to a number of successful service or device pairings.

Kenny has no fears for 'adaptable' Parrott under new boss Mourinho
Stephen Kenny believes Ireland’s Under-21 European qualification destiny will come down to their final game against Italy.
The former Dundalk manager has enjoyed a stellar first year as an international manager, leading the Under-21 side top spot in their pool with just three of the 10 fixtures remaining.
Last night’s 4-1 victory over Sweden at Tallaght Stadium all but assures them of a top-two finish, which would at the very least clinch a play-off for the 2021 finals. Ireland have never qualified for an Under-21 major tournament.
The strange dimension to Kenny’s ascent is that his final competitive games will be the double-header against Iceland and Luxembourg next March.
Under a succession planning arrangement, Kenny will have succeeded Mick McCarthy in the senior role by the time of the final qualifier away to top seeds Italy on 13 October.
“I think we will go to Italy to win the group in the final game,” said the Dubliner, looking ahead to next year’s demands.
“The players have had a brilliant year. They’ve played seven qualifiers and five games at the Toulon Tournament in June.
“Part of the job is developing players for the senior team and already some have been part of Mick’s squad. That’s great to see.”
One of those is Troy Parrott, the striker who bagged Ireland’s third goal in the comeback win against the Swedes.

Football rumours from the media: Troy Parrott to Bayern Munich?
The Tottenham Hotspur forward only linked up with the squad on matchday after McCarthy left him on the bench for their concluding Euro qualifier against Denmark 24 hours earlier.
“We put a request in to see the lie of the land if he didn’t come on (against Denmark),” explained Kenny.
“It’s an unusual sort of situation, not one I’ve been in before. When someone of his ability comes along, you definitely take him and play him.
“We’d been working on other stuff in preparing for the game. Every throw-in you get, you’re working on stuff.
“Because maybe Connor Ronan knows what we’re doing when we’re getting a throw-in, you retain possession. But every throw-in we were getting in the first half, we were giving it away. That was crazy stuff.”
Kenny has no fears about the 17-year-old superstar being disrupted by the changeover in club manager from Mauricio Pochettino to Jose Mourinho. The Argentine granted Parrott his first-team debut in the League Cup in September.
“Troy is very adaptable,” said his international boss. “Goalscorers are rare enough so you have to grasp them. He’s a natural instinctive goalscorer.”

240 Bear Paws Heading To China Seized By Security Services
by Julia BanimRussian border guards at a Federal Security Service (FSB) frontier post on the border with China have intercepted a gruesome cargo full of animal parts, including 240 bear paws.
The illegal stash also included two tiger paws, taken from an endangered Amur or Siberian tiger, as well as two extinct woolly mammoth tusks.
It’s believed the parts, which have since been seized, had been intended for China, where they would have been used for traditional medicines and food delicacies.
The cargo was uncovered at Kraskino frontier post, a security post connecting the Primorsky region of Russia with China. It’s believed the paws in question were taken from either Himalayan or black bears, which are found in the far east of Russia.
It’s feared as many as 60 bears had been slaughtered to obtain the paws, The Siberian Times reports.
According to a statement from the FSB, two Russian nationals and two ‘foreigners’ have since been detained. If convicted, the alleged smugglers could face penalties of up to seven years in prison.
Following this incident, a further 198 bear paws and two mammoth tusks were discovered in a garage at a property connected to the alleged smuggling ring in question. Officers also seized four sacks of as-of-yet unidentified animal body parts, which will now be analysed.
Sergey Aramilev, Director General of Amur Tiger Centre, made the following statement:
This is clearly a crime. The tigers are the among the most threatened big cats on the planet.
All the circumstances of the crime and all the chains in the criminal ring will be established during the investigation. It is most important to establish where are the remaining parts of the tiger.
Aramilev has expressed concerns Russian authorities are only cracking down on a ‘small part’ of a large wild animal parts trafficking operation.
Delicacies made using bear paws can reach prices of $1,000 in China, with the last ruler of the Shang dynasty, King Zhou, having been known to enjoy such dishes.
In ancient Chinese medicine, bear and tiger paws are believed to be beneficial for spleens and stomachs, and are thought to work as a cure for rheumatism. However, there is no hard evidence to support these claims.
Mammoth tusks are also known to be used for the purposes of traditional medicines and cosmetics, with practitioners grinding the tusks into powder.

In this article, I'll cover two techniques for streaming audio/video using a
few of the newer multimedia capabilities of the web platform. The first method is the
MediaSource API, an API that allows JavaScript to dynamically construct and append media segments to an existing <audio>
or <video>
element.
The second is the collaboration of binary WebSocket and
the Web Audio API to send, reconstruct, and schedule
audio chunks at precise times to produce a seamless playback.
An API designed with streaming in mind is the MediaSource API.
It's an experimental feature that allows JavaScript to dynamically append media
to an HTMLMediaElement
.
The <audio>
or <video>
media elements are frighteningly trivial to use.
That's why we like them! One sets a src
attribute that points to a media file
and boom, the browser does its thing decoding the file in whatever codec(s) it
was created with. But we're dealing with entire files here. We have no control
over what the browser does after setting that src
. For example, what if we
want to adaptively change the quality of video based on network conditions, or
splice in different sections of video from multiple sources? Aw shucks.
We can't!...without multiple videos elements and some JS hackery.
The MediaSource API is here to solve these issues. With it, we can tell an audio/video element to behave differently.
The MediaSource API is still experimental but is enabled by default in Chrome 23, with a vendor prefix:
function hasMediaSource() {
return !!(window.MediaSource || window.WebKitMediaSource);
}
if (hasMediaSource()) {
// Ready to (html5)rock!
} else {
alert("Bummer. Your browser doesn't support the MediaSource API!");
}
Using the MediaSource API starts off with our old buddy, HTML5 <video>
:
<video controls autoplay></video>
Note: the examples in this section use <video>
, but the same concepts apply to <audio>
.
Next, create a MediaSource
object:
window.MediaSource = window.MediaSource || window.WebKitMediaSource;
var ms = new MediaSource();
The source is going to be the brains behind our <video>
. Instead of setting
its the video's src
to a file URL, we're going to create a blob blob: URL handle
to the MediaSource
. This makes the media element feel special. It knows we're going to do more with it than just feed it a URL. We're going to feed it video data! Yum.
The rest of the setup looks like this:
ms.addEventListener('webkitsourceopen', onSourceOpen.bind(ms), false);
// Use MediaSource to supply video data.
var video = document.querySelector('video');
video.src = window.URL.createObjectURL(ms); // blob URL pointing to the MediaSource.
function onSourceOpen(e) {
// this.readyState === 'open'. Add source buffer that expects webm chunks.
var sourceBuffer = ms.addSourceBuffer('video/webm; codecs="vorbis,vp8"');
....
}
Only the .webm container is supported at this time.
sourceopen
fires after settings the video's .src
to a blob URL
pointing to the media source. When this happens, the <video>
is ready to accept incoming data and we can create a new SourceBuffer
in the event callback. The mimetype passed to .addSourceBuffer()
indicates what format the <video>
should expect to be handed (webm in this case).
Once we have things setup, chunks of .webm can be dynamically added to the
<video>
by appending them to the SourceBuffer
:
// Append a chunk of a webm file.
sourceBuffer.append(webmChunk);
This method takes a Uint8Array
typed array.
The previous example appended a single chunk of webm to our <video>
. However,
for the purposes of streaming, we need API functionality that lets us continuously
append new video chunks as they come in from the server.
Using range requests
If your server supports it, you can request portions of a file using the Range
header. Two APIs that support partial resources out of the box are the Google Drive API and the App Engine BlobStore API (via X-AppEngine-BlobRange
).
You can set custom headers on an XHR request using setRequestHeader()
. For instance, here's an example of requesting the first 500 bytes of a file:
var xhr = new XMLHttpRequest();
xhr.open('GET', '/path/to/video.webm', true);
xhr.responseType = 'blob';
xhr.setRequestHeader('Range', 'bytes=0-500'); // Request first 500 bytes of the video.
xhr.onload = function(e) {
var initializationWebMChunk = new Uint8Array(e.target.result);
sourceBuffer.append(initializationWebMChunk);
}
xhr.send();
I'm signifying the first chunk of a .webm file as the "initialization chunk". This first portion contains the .webm container file header information. If your videos are constructed correctly, there's nothing special you need to do here. Just make sure this first chunk is indeed the first one you append.
Then for subsequent appends, request the appropriate byte range and go to town:
sourceBuffer.append(webMChunk2);
sourceBuffer.append(webMChunk3);
...
Slicing a file
The second way to dice a file is to do things ahead of time on the server. However, for demonstration purposes, we can do so client-side using the File APIs.
As an example, here's how to use XHR to request a file and slice it into pieces
using File.slice()
:
var FILENAME = 'test.webm';
var NUM_CHUNKS = 5;
function get(url, callback) {
var xhr = new XMLHttpRequest();
xhr.open('GET', url, true);
xhr.responseType = 'blob';
xhr.onload = function(e) {
if (this.status == 200) {
callback(this.response);
}
};
xhr.send();
}
get(FILENAME, function(file) {
var chunkSize = Math.ceil(file.size / NUM_CHUNKS);
var fileNameParts = FILENAME.split('.');
for (var i = 0; i < NUM_CHUNKS; ++i) {
var startByte = chunkSize * i;
var chunk = file.slice(startByte, startByte + chunkSize, file.type);
var a = document.createElement('a');
a.download = [fileNameParts[0] + i, fileNameParts[1]].join('.');
a.textContent = 'Download chunk ' + i;
a.title = chunk.size + ' byte';
// blob urls created from file parts use original file. See crbug.com/145156.
a.href = window.URL.createObjectURL(chunk);
document.body.appendChild(a);
}
});
The important bits are:
.responseType
is set to "blob"
to inform the server we're
interested in the resource as a file rather than a string.File.slice()
is used to break up the file into NUM_CHUNKS
pieces.blob:
URL using window.URL.createObjectURL()
and
create a downloadable anchor using a[download]
.When there's no more data to append, call .endOfStream()
to indicate you're done.
This also fires the sourceended
event:
ms.endOfStream();
ms.addEventListener('webkitsourceended', function(e) {
// this.readyState === 'ended'
}, false);
Now we have everything needed for adaptive streaming. For that use case, we can detect network changes in JS and append higher/lower quality video chunks based on the connection.
To demonstrate appending video data onto a <video>
, we need a .webm movie that's
split into multiple pieces. Since you probably don't one of these laying around,
I've created the following script to do that for you. It uses file.slice()
to
break up a .webm file into NUM_CHUNKS
pieces.
Select a .webm file:
Here, we're using XHR2 to pull down the entire webm movie. The important bits to note are:
Todo
var NUM_CHUNKS = 5;
var FILE = '/static/videos/mediasource_test.webm';
var video = document.querySelector('video');
video.src = video.webkitMediaSourceURL;
video.addEventListener('webkitsourceopen', function(e) {
var chunkSize = Math.ceil(file.size / NUM_CHUNKS);
// Slice the video into NUM_CHUNKS and append each to the media element.
for (var i = 0; i < NUM_CHUNKS; ++i) {
var startByte = chunkSize * i;
// file is a video file.
var chunk = file.slice(startByte, startByte + chunkSize);
var reader = new FileReader();
reader.onload = (function(idx) {
return function(e) {
video.webkitSourceAppend(new Uint8Array(e.target.result));
logger.log('appending chunk:' + idx);
if (idx == NUM_CHUNKS - 1) {
video.webkitSourceEndOfStream(HTMLMediaElement.EOS_NO_ERROR);
}
};
})(i);
reader.readAsArrayBuffer(chunk);
}
}, false);

I defended my master's this summer, so I was not able to film as much as I wanted to.
We were fortunate to travel to a lot of different cities and towns during the summer. One weekend we were able to schedule a weekend trip to Chatham/Windsor. My parents were cool with all these dudes from Oshawa taking space on their couch, which was awesome. One of the best things I ever filmed occured during that trip. I wanted Dillon to do the Sears rail in Chatham, which has not been done since 2002, when Thadd Lenover did it. Dillon wasn't having it, so I started hyping Mikey up to do the over rail at the Municipal buildings. I told Mike that he would be a legend in Chatham if he ollied over this year. Sure enough he did it and one of my childhood dreams was realized.
I didn't film any Super 8 footage in 2018, so most of the 8mm footage is from 2017. In the video, I tried to use my BPMC Fluxus a lot. I think in the future I want to expand the different synthesizers I use. There are some sick title synthesizers that would be great. Anyways, here's the video that came from everyone's hard work.

- PHP >= 7.2
- Mysql 5.7
- OpenSSL PHP Extension
- PDO PHP Extension
- Mbstring PHP Extension
- Tokenizer PHP Extension
- XML PHP Extension
-
Deploying Backend
Follow these steps:
- Extract the
handyman.zip
on your server - For example if your domain is http://handyman.com then you will be able to access the backend as http://handyman.com/handyman/public
- Extract the
-
Configuration
All the major configuration values you will need to set in .env file which is present in root folder of the accompanied source code. Following are the most important values, you may set other values in .env as well if you have experience and requirment to do so:
- App related:
- APP_NAME: Title of your app
- APP_URL: Url of your backend
- Database related:
- DB_HOST: Database host, usually it’s localhost
- DB_PORT: Database port, incase of mysql it’s usually 3306
- DB_DATABASE: Database Name
- DB_USERNAME: Database username
- DB_PASSWORD: Database password
- Push Notification related:
Create two apps in OneSignal console, one for user and one for provider
- ONESIGNAL_APP_ID_CUSTOMER - Your OneSignal App ID that you created for customer app, https://documentation.onesignal.com/docs/accounts-and-keys#section-app-id
- ONESIGNAL_REST_API_CUSTOMER - OneSignal configuration for customer app
- ONESIGNAL_APP_ID_PROVIDER - OneSignal configuration for provider app
- ONESIGNAL_REST_API_PROVIDER - OneSignal configuration for provider app
- Social Login related:
- FIREBASE_ISS: Required to succefully login through Apple Login(only available on ios 13), Value:
https://securetoken.google.com/<firebase-project-id>
. If not setup properly authentication in your app will not work properly. - GOOGLE_CLIENT_ID: This will be used for Google authentication in android apps for user and provider. You will find the key in firebase console
- GOOGLE_IOS_CLIENT_ID: This will be used for Google authentication in ios app for user. You will find the key in firebase console under iOS App section that you will create for the project.
- GOOGLE_IOS_PROVIDER_CLIENT_ID: This will be used for Google authentication in ios app for service provider. You will find the key in firebase console under iOS App section that you will create for the project.
- FACEBOOK_APP_ID: Your facebook app id
- FACEBOOK_APP_SECRET: Your facebook app secret
- FIREBASE_ISS: Required to succefully login through Apple Login(only available on ios 13), Value:
- Stripe Payment Gateway:

-
Database
In accompanied source code you will find a sql file named
handyman.sql
. Create the database and then import the file in your database. -
Admin Panel
Admin panel is developed in Angular 7 and shipped in seperate folder. Normally you will not need to compile the files again for your deployment. If you are not going to make any change in Admin Panel source code, you can skip the angular compiling step. Following change in the file will still be required in any case:
- Open
public/admin/main.e0dc3b111fbb1158753b.js
or if you do not see this specific file openpublic/admin/main.<some-random-code>.js
file in any editor of your choice - Search for
http://opuslabs.in:9085/api/admin
and replace it with your backend url for examplehttp://handyman.com/handyman/public/api/admin
- This is a just a quicker way to make ready your admin panel so that you do not have to compile whole angular project, if you want to customize source as per your requiremtn you will need to follow steps mentione below. If you do not want customization you can stop at these step.
- Open
handman-admin.zip
, it’s an Angualr 7 based project - If you are not familiar with Angular 7 we will suggest you to get basic idea from https://angular.io/guide/quickstart
- If you need to change api url, open
<EMAIL_ADDRESS>and update the value ofAPI_BASE_URL
variable - After making the required changes issue a command
ng build --prod
- Now angular would have created/updated the
dist
folder in root with updated compiled files - You need to copy all the files in
dist
folder to you Laravel’spublic/admin
folder. - For example
cp -r handyman-angular/dist/* handyman/public/admin/
assuminghandyman-angular
is your angular project folder andhandyman
is your laravel project folder
- Open
Mobile App
-
Setup Firebase and Api keys
- Login to http://console.firebase.google.com
- Click on
Add project
to add new project -> provide project name as you like and hit Create Project. - Now you have to Register apps in this project. Click
Add app
and choose platform Android - Each app has its unique ID known as
Package name
orApplicationId
. For more info on how to name one visit https://developer.android.com/studio/build/application-id - Enter package name as asked on firebase console(once for User’s app and then for Service Provider’s app)
- Enter your app signing certificate(
SHA1
)(Optional but important in order to make features work like social login and otp verification. here is how to have one -> https://developers.google.com/android/guides/client-auth) - Click Register app. Upon succesful registration of app you’ll be provided with your configuration file(google-services.json) for that app.
- Upon registering 2 applications in your firebase project you should have 2 applicationIds and 2 configuration files(google-services.json).
- Now for api keys visit https://console.cloud.google.com/cloud-resource-manager
- Select the project you just created in firebase
- Navigate to
Api and Services
section and click “ENABLE APIS AND SERVICES” - Now Search and Enable these apis:
Maps Javascript
,Places API
,Directions API
,Distance Matrix API
,Geocoding API
- Go to credentails and copy
Browser key
- In your firebase console enable

placehodlers in config.xml and package.json for facebook setup.
Google login setup:
- For android, edit values for
WEB_APPLICATION_CLIENT_ID
andWEB_CLIENT_ID
placehodlers in package.json for google setup. - For iOS, edit values for
REVERSED_CLIENT_ID
(Regarding reverse client id: https://codesundar.com/create-reverse-client-id-for-google-login)
In src/app/app.config.ts:
- Here change
appName
(name that displayes inside application) - Change
apiBase
with your base url. For example: http://yourbaseurl.com/ - Change
googleApiKey
with the Browser key obtained in step 1. - Fill up
firebaseConfig
object details from your firebase console. - PayPal setup: Go to [https://developer.paypal.com/developer/applications/] and setup your sandbox or live app and copy client id, paste that in respective fields, i.e. “paypalSandbox” or “paypalProduction”. note:
paypalSandbox
will be ignored ifpaypalProduction
is present in app.config.ts - Stripe setup: Go to https://dashboard.stripe.com/apikeys , create app if not created, copy test(starting as pk_test_) or live(starting as pk_live_) key and paste that in
stripeKey
field in app.config.ts -
OneSignal setup: Go to https://app.onesignal.com/ , create or select your app, copy app id to paste in
oneSignalAppId
field. For field “oneSignalGPSenderId” paste in Sender ID from firebase console which was used in creation of OneSignal app. Note: you need to have seperateoneSignalAppId
for Handyman Provider app,oneSignalGPSenderId
will be same though.Your mywebapplicationclientid will look something like this<PHONE_NUMBER>03-tti40jbrr3ukb2t3abebcesl5sd0ql099.apps.googleusercontent.com. We have already demonstrated above how to get this id.
Final Checklist
In summary, make sure you have followed all these steps before proceeding
- Added project in firebase
- Added debug and release SHA-1 key in firebase
- Downloaded google-services.json file from firebase and placed it in root folder of the app source code

- Updated all the required values in app.config.ts
Useful links
- SHA-1 key related
- Google login
- Edit values for
-
Build App
Since the app depends on various native capabilities we suggest you to check the app on physical device instead of checking it in browser. Once you have followed all the steps given above you can build the app for android and ios. But keep in mind that Ionic doesn’t bundle all of the tooling required to build an app, it relies on some additional SDKs and software provided by Apple and/or Google. You’ll need to set up the platform tooling before you can preview or emulate an application on a simulator or device.
Once done, you can run following command to run the app on your Android device:
> ionic cordova run android
To build the apk, run:
> ionic cordova build android
Simillarly for iOS, you can run:
> ionic cordova build ios
If you find the given information insufficient for you to successfully build or publish the app on app/play store. Please visit https://ionicframework.com/docs/intro/deploying/ for indepth documentation.
-
Deploy App
Deploying apps on Google Play Store and Apple App Store is out of the scope of this document. Kindly refer to this guide for further instructions.

ic-get-from
- The Post-To AttributeThe ic-get-from
attribute binds the default action (see below) of HTML element to a
GET
to the given URL. For example, on a button, when the button is clicked, an
AJAX GET
will be issued to the given URL.
The value of the attribute should be a valid relative path (e.g. ic-get-from="/foo/bar"
).
ic-get-from
implies a dependency on its path, and Intercooler will issue requests for elements
whenever it detects an action that the path depends on. See Dependencies for
more information.
Here is a simple example, with a span that depends on the updated URL:
<button ic-get-from="/target_url" ic-target="#target-span"> Click Me! </button> <span id="target-span"> You haven't clicked yet... </span>

Cost analysis of running a server at your house 2007/08/10
I have always been a big fan of running my own server to have complete control over pretty much everything. I like having the power to break everything, sometimes just so I can put it back together. But is this economically sensible?
Last month, PG&E charged me $0.1143 per kilowatt-hour for electricity. My machine has a 400 watt power supply, but by best estimates it draws about 50 watts just sitting around serving web traffic. Running all day, every day, this will cost me about $4.11 for the 36 kilowatt-hours burned. Junk change. Services from (mt), TextDrive and Amazon run $50, $45 and $72 per month respectively.
I could say case-closed right here and now but let's make this interesting. I made a notable omission in my comparison above -- bandwidth. I have the distinct displeasure of being a Comcast customer and theoretically have 768Kbps upload speed. Checking with Speakeasy, I actually have 1526Kbps upload to San Francisco and 1518Kbps upload to New York City. Sweet! Whether you believe this as little as I do is unimportant -- it's a far cry from the 100Mb+ connection available to every self-respecting datacenter.
Right now the homepage of this site is 22KB (and is by far the most visited page on the site). Nevermind the poor visitor-engagement, this means that at my current upload bandwidth I can serve 8.625 requests per second. This is downright poor compared to the 568 requests per second theoretically possible on a 100Mb connection.
Of course, what would be the fun in hosting a website in an environment with stable power? PG&E sometimes cuts the power just to keep me on my toes or keep me from waking up for work, but how much does this really cost me? I don't make any money from any of my sites (not even AdSense), but if I did, here's what I'd consider.  If that amount times the number of hours of downtime per month is greater than the cost of reliable hosting, maybe the reliable hosting is worthwhile. However, even reliable hosting goes down sometimes, so you can't count all of your downtime at home against the price difference.
Whew. So now with a little qualification, I can still sleep comfortably with my server fans running and my would-be hosting money in my pocket. I need a lot more traffic and a lot more income before I spring for root-access on a box in a datacenter.
It should be mentioned that I serve this site from a TextDrive shared acount because I destroy my server so often that a simple Wordpress install does well to stay away.

You're assuming costs of maintenance, storage, upgrades are sunk -- which they are until the next time you have to upgrade or do a major update, such as replace a hard drive. The full costs -- total cost of ownership -- I'm guessing is much higher. And if you are looking to monetize (AdSense, e.g.), then your current server may be better utilized doing something else. That opportunity cost is something to consider as well.
Not that I think about these things or anything ;)

Nice article Richard. I used to have a rack of servers in my basement when I lived with my parents.. those were the days. Plenty of space and free electricity - I picked up some old SGI, IBM, and Compaq hardware on EBay and had servers running everything from Irix to AIX to FreeBSD. At any given time half of them would be broken, but it didn't matter!
These days I have a dev box at home, but run all my "production" sites (the ones that actually serve real traffic) from a dedicated (physical, not virtual) server. Deciding on a colocation vs. self-hosting vs. dedicated wasn't easy, but I think for my purposes the dedicated route was the most cost effective. The one thing you're missing in your cost analysis is the price of the server itself. To self-host you have a high upfront cost for hardware ($1000 to $1500, at least, for a decent server). With dedicated hosting you pay monthly for the server _and_ the hosting. In some situations, the money you save by not purchasing a server up-front can more than offset the additional monthly costs of a dedicated hosting solution.
The ideal solution for a smallish site, in my opinion, is to find some friends to share a dedicated box with. You can get a 100mb/s box with 2GB RAM and a sufficiently fast processor for around $100/mo (or less) from EV1Servers/ThePlanet. If you have three or four people sharing the box, that's around $25 to $33/mo each. The hard part is finding two or three people you trust who are in a similar situation.

You're both right that the cost of the machine is a big deal. Jason's right that the costs are sunk until something breaks. I could argue the hardware costs are sunk permanently because I'd probably keep a Linux box around anyway. Or we could start splitting hairs to determine how much of the hardware cost is due to server traffic. Any way you slice it, you're both right that hardware costs should play into the calculation anyway.

As others have said, you pay for the hosting and the server each month with a dedicated solution. You don't have to worry about maintenance, broken SAS hard drives which get expensive and all of that. An EC2 instance will run you a bit more than $72/month - that's only considering "$0.10 per instance-hour consumed", not data storage, transfer, etc. So maybe $75/month. ;-)
As for your main machine, you're right about it not consuming the full 400W. I have no idea what your box is like but 400W * average PSU efficiency of 70% is about 280 max Watts, but at nearly idle load you would use about 10W/stick of RAM, 10-15W/hard drive, ~30W for an idling CPU, 5-10W for fans or something like that.

Just to throw out what I'm using right now, slicehost.com , is cheaper than those other solutions at $20/month and I'm fairly happy with it thus far. At least happy enough that I'll probably keep paying even after I stop using Google's free wireless as my internet and actually have real internet again.

Jose Anigo on job security at Nottingham Forest as Sammy Ameobi reveals contract hope
Here's your daily dose of news and views from the City Ground
by Barry CooperSAMMY HAS CONTRACT HOPE
Sammy Ameobi has set his sights on a new contract at Nottingham Forest , having impressed since arriving in the summer.
The winger has proved a popular figure this season under Sabri Lamouchi, clocking up 17 appearances and popping up with a couple of vital goals.
GET IT WRONG AND YOU'LL BE FIRED
Jose Anigo is still coming to terms with life in English football, just a few weeks after being appointed as Nottingham Forest ’s new head of international recruitment.
Anigo , a former manager at French giants Marseille, admits the job is very different this side of the Channel, compared to what he’s been used to.
SAMBA ON PROMOTION AND LIFE AT THE CITY GROUND
Making your debut in English football at Fulham could be seen as something of a baptism of fire for some.
Those were the cards dealt to Brice Samba by his new manager at Nottingham Forest , Sabri Lamouchi, in late August, when the goalkeeper was handed his Championship debut at Craven Cottage.
THE SECRET TO SABRI'S RELATIONSHIP
Last month Sabri Lamouchi called for Lewis Grabban to be more like Luis Suarez.
Not necessarily the kind of aspirations you have for your player in all areas given Suarez's checkered record, but when it comes to scoring goals there are few better reference points.
Grabban is Nottingham Forest's best striker by some margin unless Rafa Mir has more to his game than he has had the chance to show yet, but Lamouchi wants more from his star man - he wants him to be 'a killer' in front of goal, just like Barcelona's controversial scoring master Suarez.
COULD COCU DEPART RAMS?
Phillip Cocu could become of interest to Feyenoord next summer, according to reports in the Netherlands.
Frank Arnesen has been appointed the Rotterdam side's new sporting director and Dutch media outlet de Volkskrant reckon he could make a move for the Derby County boss.
