Nginx FastCGI response buffer sizes

By default when Nginx starts receiving a response from a FastCGI backend (such as PHP-FPM) it will buffer the response in memory before delivering it to the client. Any response larger than the set buffer size is saved to a temporary file on disk.

This process is outlined at the Nginx ngx_http_fastcgi_module page manual page.

Verifying results

Previous versions used homebrew to install the various versions. As suggested in the comments, it's better to use pyenv instead. If you are looking for the previous version of this document, see the revision history.

$ brew update
$ brew install pyenv
$ pyenv install 3.5.0
$ pyenv install 3.4.3
$ pyenv install 3.3.6
$ pyenv install 3.2.6
$ pyenv install 2.7.10

$ pyenv install 2.6.9

For the scenario, imagine posts has a foreign key user_id referencing users.id

public function up()
{
	Schema::create('posts', function(Blueprint $table) {
		$table->increments('id');
		$table->string('title');
		$table->text('body');

A lot of these are outright stolen from Edward O'Campo-Gooding's list of questions. I really like his list.

I'm having some trouble paring this down to a manageable list of questions -- I realistically want to know all of these things before starting to work at a company, but it's a lot to ask all at once. My current game plan is to pick 6 before an interview and ask those.

I'd love comments and suggestions about any of these.

I've found questions like "do you have smart people? Can I learn a lot at your company?" to be basically totally useless -- everybody will say "yeah, definitely!" and it's hard to learn anything from them. So I'm trying to make all of these questions pretty concrete -- if a team doesn't have an issue tracker, they don't have an issue tracker.

I'm also mostly not asking about principles, but the way things are -- not "do you think code review is important?", but "Does all code get reviewed?".

Let's say you have an iOS project, and you want to use some external library, like AFNetworking. How do you integrate it?

With submodules

Add the project to your repo:

git submodule add [email protected]:AFNetworking/AFNetworking.git Vendor/AFNetworking

or something to that effect.

Basic JavaScript MVC Implementation

Despite being derived from classical MVC pattern JavaScript and the environment it runs in makes Javascript MVC implementation have its own twists. Lets see how typical web MVC functions and then dive into simple, concrete JavaScript MVC implementation.

How Web MVC typically works

Typical server-side MVC implementation has one MVC stack layered behind the singe point of entry. This single point of entry means that all HTTP requests, e.g. http://www.example.com or http://www.example.com/whichever-page/ etc., are routed, by a server configuration, through one point or, to be bold, one file, e.g. index.php.

At that point, there would be an implementation of Front Controller pattern which analyzes HTTP request (URI at first place) and based on it decides which class (Controller) and its method (Action) are to be invoked as a response to the request (method is name for function and member is name for a variable when part of the class/object).

-git tag -d 12345
-# delete remote tag '12345' (eg, GitHub version too)
-git push origin :refs/tags/12345
-# alternative approach
-git push --delete origin tagName
-git tag -d tagName
