Learning Linux really isn’t that hard, and it will dramatically increase your potential horizons as a programmer. Install Ubuntu on a virtual machine on your laptop and start running through some tutorials.[... 53 words]
If you want to send SMS via PHP I suggest taking a look at www.twilio.com—they are pretty inexpensive and ridiculously easy to get started with.[... 44 words]
This is a big decision, and it’s worth taking the time to pick what’s the best fit for you. I recommend going through the tutorials for each one, building the basic application they describe and seeing which made the most sense to you. As a Django developer, I suggest trying that framework too :)[... 126 words]
If a website doesn’t deliberately publish its server-side code (some sites like reddit do this, but it’s pretty rare) then you won’t be able to see it. You can search for an open source clone but these will often be pretty low quality—the smartest open source developers tend to work on libraries that solve common problems rather than putting their efforts in to building complete clones of existing sites.[... 175 words]
Does creating a zip file with php use more RAM then CPU? Or vise versa? Also, is it faster to use a system call, or the php zip library? Exec (zip filename.zip) vs. $zip =new ZipArchive().
You can find out the answer yourself using a very simple benchmark—just call time() before and after each option and loop them a few thousand times to calculate an average.[... 74 words]
Python will teach you more about programming than PHP—and you’ll be able to learn PHP easily if you learn Python first.[... 36 words]
System Administration: What service/product do you recommend for central logging of events and errors from multiple servers? Why?
We rolled our own solution to this using MongoDB, due to its super-fast writes and ability to store, index and search JSON. We were also attracted by its capped collections, which make it easy to e.g. only log the last 100,000 items.[... 113 words]
There are a bunch of options.[... 310 words]
It sounds like you’re pretty much screwed already, if you’re dealing with companies that still think FTPing XML around is a sensible thing to do.[... 364 words]
Is there a framework that allows me to collect input from individual users, and then charge for the aggregate and analysis of that data?
No—your needs are extremely specific. You’re going to have to build this yourself.[... 95 words]
Build a blog. Blog engines are, in my opinion, the ideal starter project for learning any server-side web technology.[... 172 words]
Can someone improve their knowledge of programming in Ruby or PHP by using a framework like Rails or Zend, or does the framework just do a lot of the work for you without giving you an opportunity to learn from it?
Read the source, luke.[... 82 words]
You don’t need to build your comet server using the same technology as the rest of your site.[... 181 words]
What are the tradeoffs (e.g. development speed, performance, scalability) between using various php frameworks, ruby/rails, or python/django? Is there any reason to choose one overwhelmingly over another?
At this point, I’d argue that the decision between them comes down to programming language rather than framework—the frameworks have mostly converged on a very similar set of features.[... 145 words]
Absolutely never. Magic quotes was a badly designed feature, and PHP has been trying to escape its legacy for years. If you are constructing SQL strings using string concatenation you’re asking for trouble—use prepared statements or a library that interpolates and correctly escapes variables for you.[... 65 words]
The Onion Uses Django, And Why It Matters To Us. The Onion ported their main site from PHP and Drupal to Django in three months with a team of four developers, including a full migration of their archived content. Their developers answer questions about the switch in this thread on the Django sub-reddit. # 25th March 2010, 6:43 pm
HipHop for PHP: Move Fast. Facebook have open-sourced their internally developed PHP to C++ compiler. They serve 400 billion PHP pages a month (that’s more than 150,000 a second) so any performance improvement dramatically reduces their hardware costs, and HipHop drops the CPU usage on their web servers by an average of 50%. “We are serving over 90% of our Web traffic using HipHop, all only six months after deployment”. # 2nd February 2010, 6:59 pm
Drupal or Django? A Guide for Decision Makers. A surprisingly interesting comparison—the author describes Django as “a framework with CMS-like tendencies” and Drupal as “a CMS with framework-like tendencies”, then explores the benefits of those two different approaches. # 15th November 2009, 10:14 pm
nginx_http_push_module. More clever design with webhooks—here’s an nginx module that provides a comet endpoint URL which will hang until a back end process POSTs to another URL on the same server. This makes it much easier to build asynchronous comet apps using regular synchronous web frameworks such as Django, PHP and Rails. # 17th October 2009, 4:48 pm
djng is nearly two weeks old now, so it’s about time I wrote a bit about the project.[... 1500 words]
Cross Browser Base64 Encoded Images Embedded in HTML (via) Scarily clever. View the PHP source to see what’s going on—most browsers get image tags that use data URIs starting with data:image/png;base64, but IE gets served a Content-type:message/rfc822 header and a MIME formatted multipart/related document, as used by e-mail clients to embed inline image attachments. # 17th April 2009, 4:12 pm
Browsing my browsing. Roo Reynolds used the MeeTimer Firefox extension to gather statistics on his browsing habits, then extracted data directly from the SQLite database and generated his own graphs using PHP and the canvas element. # 10th April 2009, 8:48 am
Database Sharding at Netlog, with MySQL and PHP. Detailed MySQL sharding case study from Netlog, who serve five billion page requests a month using thousands of shards across more than 80 database servers. # 2nd March 2009, 10:22 am
csrf_protect.php. A PHP class for applying CSRF protection to existing PHP applications, using output buffering to rewrite any POST forms on a page. Heavily inspired by Django’s CSRF middleware. Tell me if you spot any bugs! # 24th September 2008, 2:52 pm
