  File System vs Core Data: the image cache test

Code for this project is on GitHub While doing a full re-write of Droplr's iOS app for the 2.0 launch, I couldn't find any good file/image caches out there had a particular feature I really wanted: extending item expiration whenever it's touched. I set out to write my own — which wasn't that much of a challenge — but somewhere along the process I had this crazy idea that perhaps (SQLite-backed) Core Data would be a much better tool for the job: No mismatch between cache index ...

  Simplicity Oriented Programming

After few years on Warsztat (a Polish gamedev site) I’ve noticed an interesting phenomenon. Every now and then there are Compos (programming competitions) organized in two different flavours. Some compos are single-run events that last only few hours, others are long-term (several days/weeks). And as an extra catch, the former are usually restricted to basic APIs (SDL, OpenGL etc) while the latter are free-for-all (all sorts of engines, UDK/Unity allowed). Now, results are somewhat shocki...

  JavaScript Is Not A Language

Recently people presented arguments for and against using CoffeeScript. I felt the argument against was pointless and obviously wrong, but I couldn't figure out why, and I thought the counterargument for was kind of toothless and irrelevant. I've figured out the real issue.The real argument for CoffeeScript is that JavaScript is not really a language.Years ago I read something which explained, in my opinion, why Lisp has never achieved the mainstream adoption its passionate advocates belie...

  Useful Bash Scripts

Many people hack together shell scripts quickly to do simple tasks, but these soon take on a life of their own. Unfortunately shell scripts are full of subtle effects which result in scripts failing in unusual ways. It's possible to write scripts which minimise these problems. In this article, I explain several techniques for writing robust bash scripts. Use set -u ...

  Why is single threaded Redis so fast

Redis is a high-performance, in-memory key-value database. According to official test reports, it can support around 100,000 QPS (queries per second) on a single machine. However, Redis uses a single-threaded architecture in its design. Why does Redis still have such high performance with a single-threaded design? Wouldn't it be better to use multiple threads for concurrent request processing? In this article, let's explore why Redis has a single-threaded architecture and still maintains its spe...

  Write HTML easily with Emmet and Haml

Writing HTML codes is very boring and tedious as it has many tags and it's static. One solution is to use template, filling content based on other's skeleton. One another solution is high speed writing. We can write HTML codes with Emmet and Haml. These two ways have similar functions but with different characteristics. Haml is based on Ruby, so when working on Ruby/Rails projects, we recommend to use Haml, otherwise we recommend to use Emmet. 1. Emmet Emmet is a editor plugin, the official webs...
