Three things you should never put in your database
As I've said in a few talks, the best way to improve your systems is by first not doing "dumb things". I don't mean you or your development staff is "dumb", it's easy to overlook the implications of these types of decisions and not realize how bad they are for maintainability let alone scaling. As a consultant I see this stuff all of the time and I have yet to ever see it work out well for anyone. Images, files, and binary data Your database supports BLOBs so it must be a good idea to shove ...
List of Web Safe Fonts
Here is the list of websafe fonts that I use in my own personal web development. Websafe (or "web safe", "safe for the web") fonts are supposedly fonts that are common among all versions of Windows, Mac, Linux, etc. Fonts that you expect everyone viewing your webpage to have. Please contact me if you know of any other web-safe fonts that should be added to this list. These font names are in typical font-family CSS format, in other words (first choice font), (second choice fon...

Easy Parallel Processing in PHP
The proliferation of multicore CPUs and the inability of our learned CPU vendors to squeeze many more GHz into their designs means that often the only way to get additional performance is by writing clever parallel software. One problem we were having is that some of our batch processing jobs were taking too long to run. In order to speed the processing, we tried to split the processing file into half, and let a separate PHP process run each job. Given that we were using a dual core serv...

11 Important Database designing rules
Introduction Before you start reading this article let me confirm that I am not a guru in database designing. The below 11 points which are listed are points which I have learnt via projects, my own experiences and my own reading. I personally think it has helped me a lot when it comes to DB designing. Any criticism welcome. The reason why I am writing a full blown article is, when developers sit for designing a database they tend to follow the three normal forms like a silver bullet. They...

Practice of using spinlock instead of mutex
Spinlock and mutex are two important concepts in multithreading programs. They are used to lock some shared resource to prevent concurrent access which may affect data consistency. But they do have differences, what are the differences? when should we use spinlock instead of mutex? The Theory In theory, when a thread tries to lock a mutex and it does not succeed, because the mutex is already locked, it will go to sleep, immediately allowing another thread to run. It will continue to sleep until...

Java Then, Java Now - Looking at the evolution of Java from EE7 to EE9
Java, the programming language developed at Sun Microsystems in the 90s and later acquired by Oracle, is the most common programming environment used today, by developers across the globe. With the diversification of applicability that accompanied the technological boom, Java updates now come as Standard Editions (SE), Enterprise Edition (EE) and Micro Edition (ME). The Java SE contains the core programming logic and platform, used for relatively smaller-scale tasks and academic purposes. Java E...

30-Minute Exercise to Become a Better Programmer
I believe that motivation is really important. That’s why from time to time I read books about time management (as they motivate me to be focused and continue evolve my TM-system) and books about software craftsmanship. The other day I finished one of this kind of books - “Apprenticeship Patterns: Guidance for the Aspiring Software Craftsmanâ€. This book motivated me to think carefully what I want to invest my time in. Also, it coincided with my 25th birthday and, of co...

Why I left Google
Ok, I relent. Everyone wants to know why I left and answering individually isn’t scaling so here it is, laid out in its long form. Read a little (I get to the punch line in the 3rd paragraph) or read it all. But a warning in advance: there is no drama here, no tell-all, no former colleagues bashed and nothing more than you couldn’t already surmise from what’s happening in the press these days surrounding Google and its attitudes toward user privacy and software develo...

Why do I need a debugger?
When I begin to learn a new programming language, I will try and master the debugger for it as early as possible. For example, in 2013, while I touched the Go, there seems only gdb for use. Although gdb itself is not a good choice (From Debugging Go Code with GDB): As a consequence, although GDB can be useful in some situations, it is not a reliable debugger for Go programs, particularly heavily concurrent ones. But at that time there was no other choice. So after delve&nb...
Microsoft is filing a new patent about transparent display
Microsoft is filing a new patent about transparent display screen, it may be used on augmented reality technologies of tablets, phones and laptops. Similar to the scenes in the movie Minority Report. Minority Report was showed in 2002, it described a world of 2054, at that time 3D technology is mature. But after 10 years of this movie, Microsoft not only invented the basis of this technology, but also make it more portable.Patent Bolt recently revealed a patent application of Microsoft about tra...
