This weekend, those interested in Debian development have been having a discussion on the debian-devel mailing list about "What can Debian do to provide complex applications to its users?". I'm commenting on that in my blog rather than the mailing list, since this got a bit too long to be usefully done in an email.
Possibly not as horrible as I'd thought
I've had an interesting conversation on the topic of null over the last few days, spurred by the logical disaster of null. I disagreed with the statement in the post that: Logically-speaking, there is no such thing as Null This is true in some logics, but not in all logics. Boolean logic as described in...
Today, Java has a choice of a few well maintained libraries that can use Intel's MKL for fast native operations. MKL is basically as fast as you can get toda...
Recently I was working on a project where I have to cluster all the words which have a similar name. For a novice it looks a pretty simple job of using some Fuzzy string matching tools and get this done. However in reality this was a challenge because of multiple reasons starting from pre-processing of the data to…
Last time , I tried to convince you that you might not need the virtual DOM, and that many common UI patterns can be reproduced with a completely static page, with changes only happening at the leaves of the tree - attributes and text nodes. For some trickier UI patterns, I added back a limited form of dynamic…
Last time , we started making a debugger and live editor for (re)creating assembly and C programs.
I've been announcing the Open Beta release of my game HexSolve for Android and iOS. HexSolve was written in Smalltalk and people have been ...
While in the middle of writing “Reading bits in far too many ways, part 3”, I realized that I had written a lot of background material that had absolutely nothing to do with bit I/O and…
We need programming, but do we need the program?
SUNWIN tiếp tục dẫn đầu thị trường game đổi thưởng Việt Nam với hơn 5 triệu người chơi và tỷ lệ thắng cược minh bạch.
The tar format is one of the oldest archive formats in use. It comes as no surprise that it is ugly — built as layers of hacks on the older format versions to overcome their limitations. However, given the POSIX standarization in late 80s and the popularity of GNU tar, you would expect the interoperability problems to…
Massive concurrency and hardware parallelism are sexy topics in the 21st century. There are a couple of good reasons for this and one rather unfortunate one.
App developers sometimes ask me what they should do when their features, designs, or entire apps are copied by competitors.
Aftermath of how I moved stars to a great project from an simple project with undeserved stars
Recent switch of official Firefox builds to Clang on all platforms has triggered some questions about the quality of code produced by GCC c...
An introduction to the idea that code should be approached with a mindset towards compressing it semantically, rather than orienting it around objects.
October 1997: It has been six years since I finished Paradigms of AI Programming (or PAIP ), and now seems like a good time to look back at how Lisp and AI programming have changed.
Is IEEE floating-point math deterministic? Will you always get the same results from the same inputs? The answer is an unequivocal “yes”. Unfortunately the answer is also an unequivocal “no”. I’m a…
Keeping two or more copies of the same document synchronized with each other in real-time is a complex challenge. This paper describes the differential synchronization algorithm. Differential synchronization offers scalability, fault-tolerance, and responsive collaborative editing across an unreliable network.
In this post I want to explore the costs of threads on modern Linux machines, both in terms of time and space. The background context is designing high-load concurrent servers, where using threads is one of the common schemes .

All errata which readers kindly took the time to report have been addressed. Adrian Carmack has retired from anything related to id…
A recent paper suggested a new mathematical point of view on version control. I first found out about it from pijul, a new version control system (VCS) that ...
Find out what kinds of automated tests you should implement for your application and learn by examples what these tests could look like.
