Pecl errors

#redis Matt Stancliff talks about the challenges on a large open source project.

Redis is a popular key-value store used by many companies. Matt Stancliff, a Redis Core Contributor, talks about the challenges with working on a large open source project. Takes your 30 minutes, but worth it.

Update:
At first I must say that Matt is a bit prejudiced about MongoDb. but still a "must watch" video if you are interested in open source development and redis.

Hadoop at Pinterest

Big data plays a big role at Pinterest. With more than 30 billion Pins in the system, we’re building the most comprehensive collection of interests online. One of the challenges associated with building a personalized discovery engine is scaling our data infrastructure to traverse the interest graph to extract context and intent for each Pin.
We currently log 20 terabytes of new data each day, and have around 10 petabytes of data in S3. We use Hadoop to process this data, which enables us to put the most relevant and recent content in front of Pinners through features such as Related Pins, Guided Search, and image processing. It also powers thousands of daily metrics and allows us to put every user-facing change through rigorous experimentation and analysis.

Building a self-serve platform for Hadoop

Though Hadoop is a powerful processing and storage system, it’s not a plug and play technology. Because it doesn’t have cloud or elastic computing, or non-technical users in mind, its original design falls short as a self-serve platform. Fortunately there are many Hadoop libraries/applications and service providers that offer solutions to these limitations. Before choosing from these solutions, we mapped out our Hadoop setup requirements.
1. Isolated multitenancy
2. Elasticity
3. Multi-cluster support
4. Support for ephemeral clusters
5. Easy software package deployment
6. Shared data store
7. Access control layer

Metor'a destek

Hi everyone -

It's been two days since we launched the 2014 Meteor Challenge. This week until June 30,sponsors from the Meteor community are donating $5 to CodeNow every time someone new stars Meteor on GitHub. If we can introduce 5,000 people to Meteor by then, we'll raise $25,000 for kids learning to code.



We've broken $6000, we're a quarter of the way to our goal, and my twitter feed is full of #meteorchallenge-- all thanks to you. We're right on track for hitting $25,000 next Monday. Let's see if we can kick it up a notch and get there early -- I want to see how fast you can raise 3,500 more stars.

Let's each take a moment today to share the Meteor Challenge. E-mail is the most powerful way to do this -- nothing beats a direct message from a friend. Forward this to your eng@ lists, developer groups, and school listservs with a quick word on why you think they should check out Meteor and star it.



We can watch the numbers go up together at challenge.meteor.com. Give a shout on #meteorchallengeafter you've e-mailed your friends, and I'll favorite/retweet you!



PS - If you're making money with Meteor, it's not too late to join in as a sponsor! Just e-mailcommunity@meteor.com and let us know how much you'd like to pledge. More sponsors means we can raise our goal, reach even more new Meteorites, and help even more CodeNow kids.

Laravel 4.0 > 4.1 Upgrade Problem

Şurada güzelce açıklanan upgrade klavuzunu adım adım takip edince genelde sorununuz kalmaz. Ancak son denediğim güncelleme grişiminde "composer update" sırasında şöyle bir hata aldım.


PHP Fatal error:  Class 'Illuminate\Foundation\Providers\ConsoleSupportServiceProvider' not found in /home/tayyar/test/vendor/laravel/framework/src/Illuminate/Foundation/ProviderRepository.php on line 123
{"error":{"type":"Symfony\\Component\\Debug\\Exception\\FatalErrorException","message":"Class 'Illuminate\\Foundation\\Providers\\ConsoleSupportServiceProvider' not found","file":"\/home\/tayyar\test\/vendor\/laravel\/framework\/src\/Illuminate\/Foundation\/ProviderRepository.php","line":123}}Script php artisan clear-compiled handling the post-update-cmd event returned with an error

                                                                    

  [RuntimeException]                                                                                                                                                  
  Error Output: PHP Fatal error:  Class 'Illuminate\Foundation\Providers\ConsoleSupportServiceProvider' not found in /home/tayyar/test/vendor/laravel/framework/src/Illuminate/Foundation/ProviderRepository.php on line 123                                                                              

Bu veya benzer bir hata alınması halinde ilk olarak "composer update --no-scripts" çalıştırmalı. Ancak muhtemelen bu sorunu çözmeyecektir.

Sırayla

rm -rf vendor
rm  composer.lock
composer install

Artık sorununuz kalmamış olmalı.

Important Announcment on Chrome Native Messaging API


Important announcement!
Due to Chrome's abandonment of NPAPI, we had to move to a newer technology called Native Messaging API. Which is kind of good, because now we fully support Linux!
The bad news is that in order to use Devtools Terminal now you have to manually install the Node.js proxy. 

Don't worry, it's easy, here are some quick instructions to get you going: * Install Node.js (http://nodejs.org/)
 
* Open your terminal and run:  

npm install -g devtools-terminal  
sudo devtools-terminal --install --id=leakmhneaibbdapdoienlkifomjceknl


Basically, the first command will install the proxy app and the second one will tell the Chrome browser where to find it. If it didn't work for you, please, report at https://github.com/petethepig/devtools-terminal/issues Thanks

baudio by @substack

Eğer takip etmiyorsanız @substack takip edilecek kişilerdendir.

Javascript ile müzik yapmak için geliştirilmiş çok sevdiğim şu paketin de geliştiricisi : baudio

Yarım saatlik şu videosunu da izlerseniz bu paket hakkında daha çok fikre sahip olursunuz.

Baudio ile muzik yapmak javascript geliştiriciler için çok daha eğlenceli :)

Örnek :

var baudio = require('baudio');

var n = 0;
var b = baudio(function (t) {
    var x = Math.sin(t * 262 + Math.sin(n));
    n += Math.sin(t);
    return x;
});
b.play();

generate audio streams with functions with baudio npm package. Super Easy. http://t.co/y6I8AWax74

Şöyle iki şekilde yapılabilir. İlki formu olustururken, ikincisi de kökten çözüm EntityFormType içine yazarak. İkincisini yaparsanız ilgili tüm form kullanımlarında csrf olayını kapatmış oluyorsunuz.
