In some implementations of ReactiveX, there is also an operator that converts an Observable into a
“Blocking” Observable. A Blocking Observable extends the ordinary Observable by providing a set of
methods, operating on the items emitted by the Observable, that block. Some of the
To operators are in this Blocking Observable set of extended operations.
{% lang_operator RxClojure BlockingObservable.blocking interpose BlockingObservable.into BlockingObservable.seq sort sort-by sorted-list-by %}
TBD
{% endlang_operator %}
{% lang_operator RxCpp as_blocking %}
TBD
{% endlang_operator %}
{% lang_operator RxGroovy BlockingObservable.from BlockingObservable.getIterator nest toBlocking BlockingObservable.toFuture BlockingObservable.toIterable toList toMap toMultiMap toSortedList %}
The getIterator
operator applies to the BlockingObservable
subclass, so in order
to use it, you must first convert your source Observable into a BlockingObservable
by means
of either the BlockingObservable.from
method or the Observable.toBlocking
operator.
This operator converts an Observable into an Iterator
with which you can iterate over the
set of items emitted by the source Observable.
The toFuture
operator applies to the BlockingObservable
subclass, so in order
to use it, you must first convert your source Observable into a BlockingObservable
by means
of either the BlockingObservable.from
method or the Observable.toBlocking
operator.
This operator converts an Observable into an Future
that will return the single item emitted
by the source Observable. If the source Observable emits more than one item, the Future
will
receive an IllegalArgumentException
; if it completes after emitting no items, the
Future
will receive a NoSuchElementException
.
If you want to convert an Observable that may emit multiple items into a Future
, try
something like this: myObservable.toList().toBlocking().toFuture()
.
The toIterable
operator applies to the BlockingObservable
subclass, so in order
to use it, you must first convert your source Observable into a BlockingObservable
by means
of either the BlockingObservable.from
method or the Observable.toBlocking
operator.
This operator converts an Observable into an Iterable
with which you can iterate over the
set of items emitted by the source Observable.
Normally, an Observable that emits multiple items will do so by invoking its observer’s
onNext
method for each such item. You can change this behavior, instructing the Observable to
compose a list of these multiple items and then to invoke the observer’s onNext
method only
once, passing it the entire list, by applying the toList
operator to the Observable.
For example, the following rather pointless code takes a list of integers, converts it into an Observable,
then converts that Observable into one that emits the original list as a single item:
Sample Code
numbers = Observable.from([1, 2, 3, 4, 5, 6, 7, 8, 9]);
numbers.toList().subscribe(
{ println(it); }, // onNext
{ println("Error: " + it.getMessage()); }, // onError
{ println("Sequence complete"); } // onCompleted
);
[1, 2, 3, 4, 5, 6, 7, 8, 9]
Sequence complete
If the source Observable invokes onCompleted
before emitting any items, the Observable
returned by toList
will emit an empty list before invoking onCompleted
. If the
source Observable invokes onError
, the Observable returned by toList
will
immediately invoke the onError
methods of its observers.
toList
does not by default operate on any particular
Scheduler .
The toMap
operator collects the items emitted by the source Observable into a map (by
default, a HashMap
, but you can optionally supply a factory function that generates another
Map
variety) and then emits that map. You supply a function that generates the key for each
emitted item. You may also optionally supply a function that converts an emitted item into the value to be
stored in the map (by default, the item itself is this value).
toMap
does not by default operate on any particular
Scheduler .
The toMultiMap
operator is similar to toMap
except that the map it generates is
also an ArrayList
(by default; or you can pass an optional factory method as a fourth
parameter by which you generate the variety of collection you prefer).
toMultiMap
does not by default operate on any particular
Scheduler .
The toSortedList
operator behaves much like toList
except that it sorts the
resulting list. By default it sorts the list naturally in ascending order by means of the
Comparable
interface. If any of the items emitted by the Observable does not support
Comparable
with respect to the type of every other item emitted by the Observable,
toSortedList
will throw an exception. However, you can change this default behavior by also
passing in to toSortedList
a function that takes as its parameters two items and returns a
number; toSortedList
will then use that function instead of Comparable
to sort
the items.
For example, the following code takes a list of unsorted integers, converts it into an Observable, then
converts that Observable into one that emits the original list in sorted form as a single item:
Sample Code
numbers = Observable.from([8, 6, 4, 2, 1, 3, 5, 7, 9]);
numbers.toSortedList().subscribe(
{ println(it); }, // onNext
{ println("Error: " + it.getMessage()); }, // onError
{ println("Sequence complete"); } // onCompleted
);
[1, 2, 3, 4, 5, 6, 7, 8, 9]
Sequence complete
Here is an example that provides its own sorting function: in this case, one that sorts numbers according
to how close they are to the number 5.
numbers = Observable.from([8, 6, 4, 2, 1, 3, 5, 7, 9]);
numbers.toSortedList({ n, m -> Math.abs(5-n) - Math.abs(5-m) }).subscribe(
{ println(it); }, // onNext
{ println("Error: " + it.getMessage()); }, // onError
{ println("Sequence complete"); } // onCompleted
);
[5, 6, 4, 3, 7, 8, 2, 1, 9]
Sequence complete
toSortedList
does not by default operate on any particular
Scheduler .
RxGroovy also has a nest
operator that has one particular purpose: it converts a source
Observable into an Observable that emits that source Observable as its sole item.

How Frozen 2's Ending Changes the Disney Franchise
by Brandon ZacharyWARNING: The following contains spoilers for Frozen 2, in theaters now.
Disney's Frozen 2 opens up Arendelle to more magic than it was ever prepared for. But when the kingdom is threatened in the process, a group heads into the unknown to try learn more about what they can do to save their home. But along the way the structure of power in the world is radically altered, long-held secrets are revealed and even the throne changes hands.
Here's how the ending of Frozen 2 sets up the future of the franchise.
THE ELEMENTAL
After learning their parents died in an attempt to discover more about the source of her powers, Elsa pushes away her sister Anna for her own safety. Anna and Olaf end up lost in the forest and trapped in a large cave, while Elsa continues on north alone. Upon reaching the Black Sea, she tries to cross it. Confronted by the water element Nokk, Elsa tames the spirit and rides it through the ocean to reach a mysterious island.
Click the button below to start this article in quick view.
There, Elsa is able to connect with the world of magic, and fully embraces her powers. However, in the process she confronts the crimes of her family's past. Her powers allow the water to share their memories with Elsa, revealing that her grandfather built a massive dam specifically to contain magical powers. He then secretly killed the chief of the northerners during a peace meeting. That breaks Elsa's spirit, and she's overcome with the cold, and freezes in place. But the memory is carried off on the wind, thanks potentially to Gale, the air elemental.
MAKING THINGS RIGHT
The last message is able to reach Anna, who learns the truth of what her family did. Realizing the dam constructed by their grandfather is what's holding back magic, Anna has to figure out what to do bring down the dam. She attracts the attention of the enraged Earth Giants, and leads them on a chase through the woods. Although she's nearly killed in the act -- she's saved from being crushed by the timely arrival of Kristoff and Sven -- she's able to draw them to the dam.
Working with the Arendelle soldiers, Anna is able to get the giants to throw massive boulders at the dam by running across it herself. She survives, and the dam is destroyed. Magic is able to be freed, but the ensuing flood threatens to destroy Arendelle. Luckily, this surge of energy is enough to unleash Elsa, who quickly rides Nokk the water elemental and races home. She arrives just in time to freeze the wave, and save the kingdom.
THE NEW QUEEN
After the kingdom is saved, peace can return to the land. Magic doesn't lash out at humanity, and a level of coexistence is achieved. Part of that is caused by Elsa leaving the throne and joining the wilds, living alongside the native northerners and the other elemental spirits. In her stead, Anna (and her new fiance, Kristoff) will rule Arendelle. It signifies a major change in the power structure of this fantasy world.
It also means there's now a definite alliance between the forces of the wilds and the people of Arendelle. Having both worlds watched over by sisters who very much love each other should make for a powerful force in the world. Of course, if a conflict were to rise up between the two again, it might force the sisters to face off with one another. Hopefully, the power of family is enough to keep them from falling to any of that kind of in-fighting, but it's something that can be explored if Disney decides to give audiences a Frozen 3.
In theaters now, Disney's Frozen 2 reunites directors Jennifer Lee and Chris Buck and producer Del Vecho with voice actors Idina Menzel, Kristen Bell, Jonathan Groff and Josh Gad. Returning musical talents include Kristen Anderson-Lopez and Robert Lopez.

Checks ch
to see if it is a character that should not be
normally rendered on the screen. This includes all Unicode characters
with "ZERO WIDTH" in their name, as well as bidi formatting characters, and
a few other ones. This is totally different from g_unichar_iszerowidth()
and is at best misnamed.

void pango_quantize_line_geometry (int *thickness
,int *position
);
Quantizes the thickness and position of a line, typically an
underline or strikethrough, to whole device pixels, that is integer
multiples of PANGO_SCALE
. The purpose of this function is to avoid
such lines looking blurry.
Care is taken to make sure thickness
is at least one pixel when this
function returns, but returned position
may become zero as a result
of rounding.

The Internet Roasted Kanye West’s Entirely Silver Look
by Shivani SinghIt’s not unusual for Kanye West to do something extravagant and out of the box. He’s always really elaborate with the things he does and simply does not care about what other people think. Recently, Kanye, being extra as always, was covered head to toe in silver for his Mary Opera.
The production took place on a floating barge in Miami Marine Stadium, and people could not help but turn their heads when they saw Kanye was silver all over, including his skin.
The performance was only accessible by boat. Including Kanye, everybody on stage were covered in silver paint and attire. However, there were a few exceptions, like Mary, who instead wore green. Kanye read gospel passages aloud, and the cast acted out excerpts from the books of Matthew and Luke.
But, with the internet being the wonderful place it is, users could not help but poke fun at an all silver Kanye:
Kanye never fails to surprise us! Twitter really has no chill when it comes to roasting celebrities and making memes. Gotta love the internet!

Check the <useHttps>true</useHttps>
configuration item. It appears to be a bit of a secret that could handle some more exposure. It starts Atlassian SDK running over HTTPS/SSL on port 443 without the need for a proxy server. Nice.
You can add it here:
<plugin>
<groupId>com.atlassian.maven.plugins</groupId>
<artifactId>maven-confluence-plugin</artifactId>
<version>${amps.version}</version>
<extensions>true</extensions>
<configuration>
<productVersion>${confluence.version}</productVersion>
<productDataVersion>${confluence.data.version}</productDataVersion>
<useHttps>true</useHttps>
</configuration>
</plugin>
You'll need to start the server like so:
sudo atlas-run
Otherwise, you'll likely get the following error trying to bind to port 443 as a non-root user:

Yes and no. It's super easy to get going provided you remember about root permissions, but there are drawbacks.
You have to sudo
on redeploys, and well, pretty much everything you do.
This seems like overkill though:
sudo atlas-package
atlas-install-plugin
or sudo atlas-install-plugin
doesn't work as it tries to install to port 1990
for Confluence, 2990
for JIRA and so forth.
I ended up uploading the plugin via the UPM each time it was redeployed. That's just rubbish.
This however, should work nicely:
sudo atlas-install-plugin --http-port 443
I'm not sure at the moment, unless its just for a very quick test or for JIRA development. Proxying with nginx is so easy. It's setup and forget easy, at least for Confluence.

who?
Anyone heard of this Discord - Chat for Games program? Looks interesting.


Minerva is a robust Comet server and client. You can use it to build web applications that need a socket-like abstraction. Your application simply needs to send and receive strings. The Minerva server is built on top of Twisted. The JavaScript client uses Closure Library.
Some uses for Minerva: chat applications, games, real-time collaboration, dashboards, monitoring systems.
Update 2013-07-11: Minerva still works, but it is no longer updated. There is some minimal documentation (tutorial files and DemosMinerva) for the curious. We recommend using WebSocket, RTC Data Channels, Flash socket fallback, and/or a reliable Comet protocol like Google's BrowserChannel. It's important to use a Comet implementation that guarantees in-order delivery of all data using ACKs in both directions.
View demos Tutorial (soon!) On GitHub Bug trackerJump to: Highlights • Disclaimers • FAQ • Contact
Highlights
- Reliable and in-order message delivery over HTTP. Both client and server use
TCP-like ACK logic to ensure reliability. Minerva doesn't make these incorrect assumptions:
- If an HTTP response is sent, it will be received by the client.
- If an HTTP response is received, it will be fully received.
- If HTTP requests A and B are made, the server will see A first.
- Support for many connections per domain: To work around browsers' per-domain active request limits (usually just 4-6 requests), Minerva can send HTTP requests to random subdomains. Your web application will work as usual when you open it in a dozen tabs. (For HTTPS, a wildcard cert is required.)
- Serialization-agnostic: You're free to use JSON, Base64, or your own serialization format. And there's no double-serialization to get in your way.
- Cross-browser: Minerva works in old and new versions of IE, Firefox, Chrome, Safari, and Opera. We aim to keep Minerva working in every JavaScript runtime that can make HTTP requests.
- Robust timeout logic: Stuck requests and sockets are detected and aborted.
- Licensed under Apache License, Version 2.0.
Disclaimers
Go ahead and try out Minerva because it should work well, but keep in mind that right now:
- The API isn't stable yet. It will be soon, after some initial feedback.
- There's no cross-domain support yet. Right now, website.com can only connect to a Minerva server at *.website.com. If you really want cross-domain support, you can use Closure Library's cross-domain support (goog.net.xpc) combined with the Minerva client in an iframe.
- If you don't want to use Twisted or Closure Library, you'll have to do some legwork. We'll soon have better support for non-Twisted and non-Closure Library users.
- Despite HTTP streaming and Flash sockets working, there's no automatic negotiation between HTTP long-polling/HTTP streaming/Flash sockets yet. For Internet-facing applications, use just long-polling for now.
FAQ
What about WebSocket?
Minerva's HTTP transport (which uses XHR on the client) means that if a user can load your website, they can also connect to your Minerva server, as long as they have JavaScript enabled. This isn't the case with WebSocket, because (1) browser support is still poor (2) even in browsers that support it, many networks make WebSocket connections impossible. Google reported success rates of 67% (port 80) to 95% (port 443).
As far as we can tell, there's no good reason to implement a Minerva transport that uses WebSocket. Your web application can just use Minerva as a fallback for when a WebSocket connection fails. Alternatively, it can use Minerva as the initial connection method, for potentially faster connection setup. We'll soon document some ways to use both Minerva and WebSocket.
Note that WebSocket is vastly superior to HTTP transports in this use case: sending small messages frequently from the client to the server. If you use HTTP transports for this, the client wastes bandwidth by sending the same HTTP headers for every message. But for most applications, Comet-style HTTP transports work fine.
Do I need to use Twisted?
For now, yes. In the future, we might have an TCP gateway and a WebSocket gateway. These will allow you to use Minerva's reliable HTTP transports without writing any Python/Twisted server code; you will just specify a TCP/WebSocket server for Minerva to proxy to.
How many simultaneous connections can the server handle?
Somewhere around 10,000-20,000 per Minerva server. If you run your own benchmarks, remember to: (1) select the best Twisted reactor for your OS (epoll on Linux) (2) think about TIME_WAIT sockets: they might clog up your benchmark (3) try PyPy.
Why not 100,000 or more? Minerva was built for correctness, not for maximizing connection count. There are three mitigating factors:
- You can run a Minerva server for every CPU you have.
- Minerva works on PyPy, and it'll keep getting faster.
- WebSocket will soon work for more users, and you can bypass Minerva entirely for your WebSocket connections.
The client uses Closure Library. Does this use Google's BrowserChannel?
No, but the Minerva protocol does solve the same problems as BrowserChannel.
I'd like to read the code. Where do I start?
The guts of the server are implemented in mserver.py and the client in client.js. Consider reading it in IDEA so that can jump to function definitions quickly. Your understanding may be assisted by a sketch of how Minerva works, the frame types used by the Minerva protocol, and by playing with /chatapp/?mode=http
on the minerva_site
server. Understanding the separation between the stream and the transports is critical. You're welcome to ask questions about how Minerva works, or why it works a certain way.
Why are Minerva strings restricted to 95 codepoints (" " 0x20 to "~" 0x7E)?
This design decision simplifies Minerva and helps keep the API stable if new transports are added in the future. The codepoint range doesn't seriously impact most applications: you can use JSON (encoded as ASCII-only), or Base64, or even higher Base* encodings. This decision is left to you.
Supporting more than this codepoint range would make Minerva more fragile to changes in the transports it uses. For example, XMLHttpRequest can't receive 0x00 in IE and Opera. XMLHttpRequest's readyState 3 and Unicode often don't mix (especially in older Firefox versions). XDomainRequest (IE8+) replaces a large number of non-Character Unicode codepoints.
What other software has any kind of Comet implementation?
Free: Lift's Comet support, Divmod Nevow's Athena (homepage dead), Atmosphere, gwt-comet, Socket.IO, nginx_http_push_module, Meteor, Perservere's Comet support, gwteventservice, Orbited, HookBox, js.io, APE (Ajax Push Engine), DWR (Direct Web Remoting), ICEpush, Google's BrowserChannel (several servers available).
Commercial: GAE's Channel API, Migratory Push Server (supports very high connection counts), StreamHub, WebSync (.NET), Liberator, Kaazing, Lightstreamer, ZK's push support.

@ionstar [discord] <jl777c> with our fast action, we rescued about 8 million KMD and over 100 BTC, but as of now it seems about a million KMD has been stolen. I am working on a plan that I hope will be an acceptable outcome to most. Please be aware that even if your funds got swept, there are others that have nothing left and i would like to come up with a plan where nobody is wiped out. in order to do this, we need as accurate of a damage assessment as possible. So please make sure to file a claim with your details as soon as possible so we can get a handle on what actually happened.
once we quantify the actual problem at hand, then we can make a specific plan. I would like to make all the smaller accounts 100% whole, but there isnt enough funds for all accounts to be 100%. I think if the big amounts ends up around 80% to 90%. As long as the damage is less than a million KMD, then I will be able to find the funds to cover it, but if it is more than a million, well we will cross that path if it turns out that way.
So for now, we need to be able to assess the scope of the damage, it could be that we wont have 100% of people claiming and the 5% rewards (400,000 per year) can end up covering most of the claims if they are coming in over time. What does it mean to be a small account? A big account? I dont know yet. I am without sleep for over 30+ hours and I dont want to make any decisions in this state.
Please be patient and file your claims, that is what will help the most. The general plan is to protect the smaller accounts fully, make sure nobody is wiped out, use 5% rewards to cover some of the costs and I will also personally put in half a million KMD. Until we have the accurate numbers, we can only guess as to the specific plan.


In late november my friend and I decided to buy 5 grams of mushrooms. They are called gold caps I believe. We split them in half and ate them at once. It was both of our first time and we didnt know how exactly it would be. We were excited to do them because it took forever for us to find them.
We walked to the movie store and I returned a movie and I started feeling like I didnt belong in there and so did she. We left and started walking back to my apartments and to my suprise the ground was more vivid. I could see the smaller things more vividly more then the larger and it started waving up and down and side to side, what seemed to be a start of a good time it slowly went downhill. We got into my apartment gates and there was a long stretch of maybe 500 feet or so but it was like walking down a long hallway it looked a mile away. And for some reason I started feeling uncomfortable like everything I did wasnt right and I became slow and partially confused. I knew what was going on but I just felt like I wasnt all there. So we were talking and decided to go to the jacuzzi and sit in there. As were getting dressed we both noticed it took us like 15 minutes to put shorts on. (well in my case).
Were finally ready and I start feeling sick and I start throwing up in the bushes out front. Right there was where things started getting more confusing. Everything started bending and getting colorful. Truly it was amazing but the way I was feeling killed the whole 7 hours of hell. Were at the jacuzzi and I'm trying to feel better and make myself think better but thinking became a hard task and I couldnt get out of the grasp of fear and disorder. 20 minutes pass and both of us started feeling the same way. But we didnt know how long and far the effects were gunna go. I was thinking the best ways possible but nothing seemed to help. We both felt helpless and I tried analyzing everything because she had no clue what anything was. I felt the same but I tried making a reality out of something so unrealistic.
We started making our ways to her house and I was trying to talk reality but like I said, reality was gone. Colors, waves, sound waves, anything that moved I could sense and anything I heard scared me. I had to get used to different settings. I didnt know if I wanted the lights on or off or the tv on or off…both were too overwhelming. So my friend tells her mom what happened and she flips out but shes a cool mom she didnt care that much, just to her suprise was the worst.   The only thing that helped me overcome the living nightmare was the fact that everything passes and everything goes away. Seconds seemed like minutes and minutes seemed like hours and hours seemed like days.
About 2 hours into it we went outside and it was raining and it looked like colorful crystals falling from the sky and they would reflect off the christmas lights. I was hungry but food tasted old and drinks tasted flat so my appetite was completly teased. The whole high lasted 7 hours and all I did was lay down for the most part of it. Colors spiralled around the room and faces bent and walls were wavy opening locks on a door was a challenge. I was hopeless, I felt like nothing, I felt weak but I felt determined to keep a positive state of mind. So we turned on americas funniest home videos and I remember watching one that the guy said this is what it sounds like when you rewind your cat and it just tripped me out cuz it sounded like rewinding a tape recorder but it was a cat.
After about 6 hours I started coming down and I felt better and started exploring everything. Everything was almost the same way it was but my cloudy thinking seemed to just dissapear time sped up and later became a memory. It took me about 7 months to try mushrooms again but I havent eaten as much at one time as I did then. On a personal level I prefer LSD over mushrooms because I didnt seem to have a cloudy mind on LSD. But the experience taught me to research things a little better before I try them.
Mushrooms was the most intense high I've ever had and I never will have a high this intense again.

EasyAnt comes with a module named skeleton that allows you to create or install project skeletons. This could be pretty useful to quickstart a project.
By default, this module works in interactive mode, which means that easyant will ask you questions for every required property. But you can still give parameters on the command line using -Dproperty. Interactive mode can be disabled by setting skeleton.interactive.mode=false.
> easyant skeleton:select
skeleton-select: [echo] Choose a skeleton in the following list: [ea:searchmodule] 0: std-java-webapplication v0.1 (Skeleton for creating standard java web application) [ea:searchmodule] 1: std-ant-plugin v0.1 (Skeleton for creating ant based plugin for easyant) [ea:searchmodule] 2: std-java-application v0.1 (Skeleton for creating standard java application) [ea:searchmodule] 3: std-skeleton v0.1 (Emtpy skeleton structure) [ea:searchmodule] Choose a number: (0, 1, 2, 3)
[input] The path where the skeleton project will be unzipped [.] [input] Organisation name of YOUR project org.mycompany [input] Module name of YOUR project myProject [input] Revision number of YOUR project [0.1]
If you prefer to use it in that way you should use ":generate" target. Example if your skeleton module is imported as "skeleton", you should use :
> easyant skeleton:generate
[input] Organisation name of the skeleton project org.apache.easyant.skeletons [input] Module name of the skeleton project std-java-skeleton [input] Revision number of the skeleton project 0.1 [input] The path where the skeleton project will be unzipped [.] .

--- layout: page weight: 0 title: Event V1/V2 (deprecated) navigation: show: true --- {% warning %} V1 and V2 of this webhook are being deprecated. Version 3 is the recommended option and the only option available to new users. {% endwarning %} {% anchor h2 %} Requests {% endanchor %}
You have the option to receive a HTTP POST request for each event ("Version 1") or to receive a batch of multiple events in one request after a very short delay ("Version 2"). These POSTs will be sent to the URL you have defined in the Event Notification app options.
SendGrid expects a 200 HTTP response to the POST, otherwise the event notification will be retried. If your URL returns a non-200 HTTP code it will be deferred and retried for 24 hours. The maximum number of deferred POSTs in the retry queue is 100,000. If the queue is full, the oldest request in the queue will be removed to make room for the newest deferred POST. This means that if you use batched events these events will drop due to 24 hours before the queue can max out. Events that cannot be submitted within the maximum retry period or events removed from the defer queue will be lost.
{% warning %} If your email traffic generates lots of events, the incoming amount of data can easily overload a web server if not configured properly for scalability. To reduce the number of requests to your server, enable the batched events option.The following lists the events generated by SendGrid.
| Event | Criteria |
|---|---|
| Processed | Message has been received and is ready to be delivered. |
| Dropped | You may see the following drop reasons:
|
| Delivered | Message has been successfully delivered to the receiving server. |
| Deferred | Recipient's email server temporarily rejected message. |
| Bounce | Receiving server could not or would not accept message. |
| Open | Recipient has opened the HTML message. |
| Click | Recipient clicked on a link within the message. |
| Spam Report | Recipient marked message as spam. |
| Unsubscribe | Recipient clicked on messages's subscription management link. |
The following image shows where events can be generated as email is being processed:
{% anchor h2 %} Default Parameters {% endanchor %}The following parameters are always passed with each event. Some events include additional parameters. Also a category name and custom argument may be passed. Please see the Custom Parameters and Categories section below for more information.
| Parameter | Description |
|---|---|
| event | One of: bounce, click, deferred, delivered, dropped, processed, open, spamreport, unsubscribe |
| Email address of the intended recipient | |
| useragent | The user agent responsible for the event, e.g. "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_8_4) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/28.0.1500.95 Safari/537.36" |
| ip | The IP Address where the event originated. |
| sg_event_id | A unique id for the event. This is a 23 byte string. |
Events generated by SendGrid can also include unique arguments. To define and receive custom parameters in your URL the SMTP API must be used when sending emails using the unique_args argument. For example, if you have an application and want to receive custom parameters such as the user id and the email template name, include the following in your SMTP headers as X-SMTPAPI or as the xsmtpapi parameter of your Web API call:
{% codeblock lang:json %}{ "unique_args": { "userid": "1123", "template": "welcome" } } {% endcodeblock %}Either of those emails will generate the following HTTP POST request to your application when the email is opened:
{% codeblock %}<EMAIL_ADDRESS>{% endcodeblock %} {% anchor h2 %} Categories {% endanchor %}If a category is used over the SMTP API to get detailed statistics for user signups in addition to custom parameter, include the following in your SMTP headers as X-SMTPAPI or as the xsmtpapi parameter of your Web API call:
{% codeblock lang:json %}{ "unique_args": { "userid": "1123", "template": "welcome" }, "category": "user_signup" } {% endcodeblock %}Either of those emails will generate the following HTTP POST request to your application when the email is opened:
{% codeblock %}<EMAIL_ADDRESS>{% endcodeblock %} {% info %} If you apply multiple categories to any of your outgoing messages, the returned data will be in the form of an array. {% endinfo %} {% anchor h2 %} Batched Events (Version 2) {% endanchor %}Batched event POSTs have a content-type header of application/json, and contain exactly one JSON string per line, with each line representing one event. Please note that currently the POST headers define this post as application/json, though it's not; each line is a valid JSON string, but the overall POST body is not. For example:
{% codeblock lang:javascript %} {"email":"foo@bar.com","timestamp":1322000095,"unique_arg":"my unique arg","event":"delivered"} {"email":"foo@bar.com","timestamp":1322000096,"unique_arg":"my unique arg","event":"open"} {% endcodeblock %} {% info %} Batched events currently post every 1 second, or when the batch size reaches 1MB (one megabyte), whichever occurs first. {% endinfo %} {% info %} Batching your events is recommended to reduce server load and reduce the number of open connections. {% endinfo %} {% anchor h2 %} Examples {% endanchor %} The following examples will use PHP language, the Web API to send email using curl, and the SMTP API for the X-SMTPAPI parameter when sending email. Many times is useful to see all parameters that are being POSTed. The following example receives a batched POST and dumps the parameters to a log file located at /tmp/dump.log: {% codeblock lang:php %} ok {% endcodeblock %} If you're not batching, the code would look like: {% codeblock lang:php %} ok {% endcodeblock %} {% info %} If you are using a hosting service, you don't have direct access to the server's file system. In that case, you need to modify the path for the dump log to be somewhere you do have access to. In most cases, the second line in the code above... {% endinfo %} {% codeblock lang:php %} {% endcodeblock %} should be changed to... {% codeblock lang:php %} {% endcodeblock %} {% anchor h2 %} Parameter Details {% endanchor %}The following shows each type of event that can be posted along with the specific parameters that go along with the event.
{% info %} You can use the SMTP API to specify additional custom parameters including categories and unique args. Each unique arg is posted as a separate post parameter, similar to the category listed below, but with a custom name specified by you. {% endinfo %} {% anchor h2 %} Processed {% endanchor %}| event | category | |

Ensure that your web server is returning a 200 response to our servers. Any other response type will result in our server retrying a POST until we receive a 200 response or the maximum time has expired. All events are retried at increasing intervals for up to three days after the event occurs. Make sure you are not blocking our IPs that are trying to POST to your server. Our IPs change often since we constantly add more machines. Also, you can try a test POST yourself from a terminal by running the following command. This will give you the full response your server is returning including the HTTP headers.
{% codeblock lang:bash %} curl -i -d<EMAIL_ADDRESS>{% endcodeblock %}

Inserts the contents of the edition into the active sheet at the point of the current selection. Use SUBSCRIBE.TO to incorporate editions published from other workbooks into your Microsoft Excel worksheets and macro sheets. SUBSCRIBE.TO returns TRUE if successful.
Syntax
SUBSCRIBE.TO(file_text, format_num)
Important This function is only available if you are using Microsoft Excel for the Macintosh with system software version 7.0 or later.
File_text is the name, as a text string, of the edition you want to insert into the active sheet. Unless file_text is in the current folder, supply the full path of the workbook. If file_text cannot be found, SUBSCRIBE.TO returns the #VALUE! error value and interrupts the macro.
Remarks
If a single cell is selected, the data from the edition file is placed into as large a range of cells as is required by the data. Data already present in those cells is replaced. If the data is a picture, it is inserted from the upper-left corner of the selected cell.
If a range of cells is selected, and the range is not big enough to contain the edition data, Microsoft Excel displays a dialog box asking if you want to clip the data to fit the range.
Format_num is the number 1 or 2 and specifies the format type of the file you are subscribing to.

Compared to images, loading video data is expensive due to the I/O bottleneck and increased decoding time. This reduces efficiency leading to significantly longer training times. Reading online, there are generally two solutions for data loading videos:
- Decode the video and save its matrix as is
- With this approach, we improve the speed by preprocessing the decoding; however, we aren’t compressing, so storing a few videos which total a couple MBs ends up requiring a few GBs; not very memory efficient.
- Store the frames of the video as images using a folder filesystem
- With this approach, the I/O limitations are reduced by reading the images directly and we take advantage of compression algorithms like JPEG. However, it would also require a large folder re-organization which isn’t optimal.
The solution I came up with and will share with you is to store the video as a list of encoded images using TFRecords. This significantly improves data loading throughput (by at least 2x) without incurring large memory costs (maintains the same size).
Setup
Software
This code is written in Tensorflow 1.15.0
; it should also work with Tensorflow 2
.
Data format
For this tutorial we need a .txt
file for train, validation and test which is formatted like the following:
{mp4 file path} {label}
For example, one line would look like:
videos/54838.mp4 1951
Creating the TFRecords
First, we look at how we create a TFRecord example from a video example.
Then we loop through our dataset and save each example into a TFRecord.
Reading the TFRecord
The most difficult part was figuring out how to decode the sequential frame data.
With simple solutions not working, being unable to find online resources and on top of it all working in mysterious bytes I created the solution through brute force. The result was a magical TensorFlow while loop.
Conclusion
That’s it! Now you know how to encode and decode video data efficiently using TFRecords, happy hacking! :)
A repo containing the full code can be found here!
If you enjoyed this post, you may enjoy my other posts! If you want to stay up to date you can find me on my Github or Twitter
Why I made this
- Difficult to find resources which are compatible with
Tensorflow 1.15.0
(mostly becauseTensorflow 2.0
is out) - Lack of quality resources on how to use TFRecords with video data
- Imo this is the best way to data load video data using Tensorflow
- With video processing being such a cool field I’m sure many others will find this information useful in future research!

Knowing the usage of the fonts is very important skill that every designer should have for creating beautiful web pages. There are nine font families that are most common and supported by the both major operating systems (see picture below). Those families are called the safe list. The font-family of CSS allows you to choose differents fonts in the order of its preference (this is referred to as a font stack). Any user can use the fonts for the future designs.
If you want to the visitors to see some text in a specific typeface you should to replace the text with an image. You can mark up your text as text and then use CSS to create a link the size of your image. Also, you can try to use the Phark Method of image replacement which involves setting the image that you want to use as the background of the element. After this step, you should add a negative text-indent value high enough to move the text content out of the block.
There are four ways how the text on your web page can be located:
Left aligned - the text is located on the left side of the page, the “ragged edge” is on the right.
Right Aligned - the text is located on the right side of the page, the “ragged edge” is on the left.
Centered - text is located at the center of the page. Centered text is usually used for document titles and may be appropriate for headers and footers.
Justified - the text combines left and right aligned text. By using justified text there could be big gaps between the words, so, the justification usually works well for the newspapers and the magazines.
I hope you like my Typogrphy web page!


safe_in_place_editing_helper.rb
Hipposoft 2008
Safe, lockable in-place editing - helper methods.
24-Jun-2008 (ADH): Created.
Exact API equivalent of in_place_editor, except fixes various bugs (see README for the rationale) and:
New option “:lock_var”, which is the name of a global variable to be used in the JS domain to track the lock version at the client side. By default set to nil, meaning no optimistic locking support. Options value “:lock_version” MUST be set to the lock version of the object for which the in-place editor is being created in this case. The variable is incremented each time the object is successfully updated through the in-place editor, since the server will have incremented its lock version so the client must keep in step. If someone else edits the item, the client and server lock versions will not match and the update will fail, which is the desired result.
The “:save_text” option is set to “OK” by default, since I detest that nasty lower case “ok” button that’s produced by the JS code otherwise.
The “:cancel_text” option is set to “Cancel” by default to match the above change.
Custom on-failure and on-complete functions are used. To try and reduce the code bulk for each instance of the editor, hard-coded JS function names are used with the support code placed in ‘safe_in_place_editing.js’. See there for a reference implementation if intending to write customised equivalents. To override the default names of these functions for any reason, give the names as strings in options properties :on_complete and :on_failure, then make sure appropriate JS functions are actually defined.

Close API equivalent of in_place_editor_field, except fixes various bugs (see the README for rationale). Allows either an object name in the first parameter (e.g. “:foo”, in which case instance variable “@foo” must point to the object instance of interest) or an object instance (to save messing around with magic instance variables, but obtains the object name from “class.name.underscore”, so may not be appropriate for unusual object classes). Anyway, clearer error reporting and the ability to pass in an object reference directly may help avoid a common error experienced with the InPlaceEditing plug-in code, as described here at the time of writing:
oldwiki.rubyonrails.org/rails/pages/InPlaceEditing
Includes the following options:
:lock_var is the name of the variable used for optimistic locking, by default set to a row-unique value. The assumption is that this same variable gets used throughout the row so that multiple edits on that row all cause the same variable to be incremented. If your back-end update function has side effects that might invalidate the value shown in another column on that row - which would be pretty strange! - you’d need to override the lock variable name with something that’s unique to both the row and the column. When using a lock variable, additional option “:lock_version” is always set internally to the lock version of the object for which the field is being built and cannot be overridden.
:with is extended to include a “lock_version” parameter in the query string so that the client side’s idea of the current object’s lock version may be communicated to the server’s attribute update action. This is done internally; there is no need to set the option yourself.
The Prototype library getText function must be patched as described in the README rationale; “application.js” is a good place to do this.
Note an optional fifth parameter which if ‘true’ will prevent HTML escaping of the value for values which are really meant to contain HTML code. Be very, very careful with this.
