Here’s a new addition to all the web resources dedicated to the PHP programming language – PHP Internals.
This website is dedicated to providing resources on PHP’s internals. All content covers PHP 7+, with the documentation typically targeting the current master branch of php-src.
It is the end of an era for me, and for once it’s me ending it and not yet another web service or social network disappearing. Today I’m saying goodbye to Foursquare and Swarm.
I have been one of the early adopters of Foursquare and an active user for a few long years. I loved it from the moment I heard about it. The idea was brilliant and the implementation was good too.
For me, Foursquare was a very elegant idea of a social network. The combination of the city guide with crowd sourcing and a gaming component was cool.  It provided an easy way to find new places, get recommendations, reviews, and tips, and wrapped it all in a points system that made sense.
I thought that it was also useful for the business owners – knowing who checks in at your bar or restaurant, where else they go, how often they come, and what they think is great. Being able to offer promotions and special offers based on the check-in history of a user, I thought, was genius as well.
But for some reason, Foursquare never really took off. Sure, I loved it and recommended it to every person with the mobile phone. But it never quite got as mainstream as, say, Facebook. Pity.
But then things got worse. Foursquare has split the mobile app into two – Foursquare as a city guide, and Swarm as a game.  Swarm is still feeding Foursquare with content, but now there is no particular reason to install Swarm and use it. I don’t think there was a single new user or anyone who just uses Swarm, without Foursquare. I might be wrong, of course. But from what I’ve seen, even fewer people were now checking in and contributing. Those who did were mostly doing so out of habit from the good old days. As did I.
A few days ago, something else happened, which, for me, was the last drop. My Swarm app kicked me out and asked to re-authenticate. This was weird. But I did it anyway. And then, for some reason, all my history was gone. I still had those few friends in, and my settings were all good. But the history began anew. What? No! Sure, I can dig into it and figure out if I did something wrong. Or I can contact support and let them fix it. But what’s the point anyway?
There is no benefit to using Swarm anymore. It’s points for the sake of points. So I’m over and out.
Goodbye Foursquare and Swarm. It was fun while it lasted.
idg is a very handy tool for programmatically generating images which look like documents and web page templates. It’s built on top of the ImageMagick and will come native to anyone familiar with the modern grid-based web design.
Carbon – is a very simple, but very useful web tool for creating beautiful screenshots of the source code. And yes, before you start correcting me, I know that source code is always more useful as a listing, which can be copy-pasted, searched, and so on, rather than an image. But there are still plenty of scenarios when you just need it fixed and frozen.
Carbon provides plenty of flexibility in a very friendly user interface – code highlighting for a variety of programming languages and configuration files, editor themes, window controls, fonts, and more.  There’s also a very simple way to tweet the screenshot directly from Carbon, if that’s what you want to do.
Machine learning is rarely mentioned in the same sentence (or article, for that matter) with PHP, so each time this happens, I’m all ears. Here’s one that I came across recently – How to Analyze Tweet Sentiments with PHP Machine Learning.
Unlike many other “hello world” kind of examples, this article examines a real and quite common problem, which can be easily adopted to other similar problems – SPAM filtering, marketing segmentation, fraud detection, etc.
