Back in December of 2004 I started a new life from zero. I was 22 years old without any money, education or connections. I borrowed my mothers computer and started to learn HTML and internet marketing. That is now little more than 10 years ago and each year I publish an annual report. Earlier reports [...]

Or how to detect and correct errors Last time we made a quick tour through the main theorems of Claude Shannon, which essentially solved the following two problems about communicating over a digital channel. What is the best encoding for information when you are guaranteed that your communication channel is error free? Are there any encoding schemes that can recover from random noise introduced during transmission? The answers to these ques..

RyuJIT will be available soon. It is a next generation JIT-compiler for .NET-applications. Microsoft likes to tell us about the benefits of SIMD using and JIT-compilation time reducing. But what about basic code optimization which is usually applying by a compiler? Today we talk about the loop unrolling (unwinding) optimization. In general, in this type of code optimization, the code for ( int i = 0 ; i < 1024 ; i +..

The question of location comes up a lot in software consulting. Will the work be done on the client’s premises, or the consultant’s? There’s no right answer. Some clients don’t have the office space to accommodate an entire development team. Others already have a large IT department and want the consultancy’s team co-located with their existing staff. Working at the consultancy’s office may afford certain perks like a relaxed dress co..

Sometimes I want to know used JIT compiler version in my little C# experiments. It is clear that it is possible to determine the version in advance based on the environment. However, sometimes I want to know it in runtime to perform specific code for the current JIT compiler. More formally, I want to get the value from the following enum: public enum JitVersion { Mono , MsX86 , MsX64 , RyuJit } It i..

It's the end of February and this game is supposed to be content-complete. In a sense, it actually is. All the levels are done. Twenty in all. I thought this month would never end! Just so you know, there are sixty of those lights and I had to hook up each one individually. It fell just barely beneath the "worth it to automate" threshold . Don't look too closely at this next one, it's a bit spoilery.

Watching Movies and TV Shows from online streaming sources is a pain, as you depend on the availability of the your ISP network and current status of the stream provider. Furthermore, you don’t always have an internet connection available when you want to spend some time in front of the TV. So downloading it it’s a much better way to go in order to avoid this issues (giving that you have to anticipate a little bit to get downloads finished)....

HackerEarth’s web servers handle millions of requests every day. These request logs can be analyzed to mine some highly useful insights as well as metrics critical for the business, for example, no. of views per day, no. of views per sub product, most popular user navigation flow etc. Initial Thoughts HackerEarth uses Django as its primary web development framework and a host of other components which have been customized for performance ....

Vagrant is a great tool for development, but Red Hat Enterprise Linux (RHEL) customers have typically been left out, because it has been impossible to get RHEL boxes! It would be extremely elegant if hackers could quickly test and prototype their code on the same OS as they’re running in production. Secondly, when hacking on projects that have a long initial setup phase (eg: a long rpm install) it would be excellent if hackers could ro..

Introduction One of the things I love about Go is the profiling and debug information you can generate. There is a special environmental variable named GODEBUG that will emit debugging information about the runtime as your program executes. You can request summary and detailed information for both the garbage collector and the scheduler. What’s great is you don’t need to build your program with any special switches for it to work.
