  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 ...

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...

  Convert number to string in C++

Prior to C++11, there is no built-in function in C++ standard library which can be used to convert numbers such as interger and double number to string.  There are many ways which can convert number to string. Since C++ is C compatible, we can use itoa() function to convert an integer to C style string. But this one can only convert integer to string, not double. For different types of numbers, we need to use different functions. string s = string(itoa(a)); Actually, we can also use strings...

  The requirements of DevOps development

DevOps has become a popular and commonly adopted software development model in IT industry in recent years. Its popularity is partially because it advocates it could improve software development efficiency, delivery speed and cost saving. This is especially favored by managers who become the main force to promote this type of development model in their companies. However, we must be cautious about DevOps model as well. With their advantages, they also bring challenges to development teams and th...

  Get the 48×48 or 256×256 icon of a file on Windows

Getting the 16×16 and 32×32 icons on Windows is relatively easy and is often as simple as one call to ExtractIconEx. However, getting the extra large (48×48) and jumbo (256×256) icons introduced respectively by XP and Vista is slighly more complex. This is normally done by: Getting the file information, in particular the icon index, for the given file using SHGetFileInfoRetrieving the system image list where all the icons are storedCasting the image list to an IImageList interf...

  What’s Your Start-up’s “Bus Count”? 7 Myths of Entrepreneurship and Programming

Software development is a rapidly evolving field that got off to a very rocky start. Conventional wisdom for many years was that software engineering should be like other types of engineering: design carefully, specify precisely, and then just build it – exactly to spec. Just like building a bridge, right? The problem with this approach is that software is just that. Soft. It’s endlessly malleable. You can change software pretty much any time you want, and people do. A...

  Why developer-friendliness is central to API design

Today, APIs play a bigger role in software development than ever before. The evolution of computing has been dominated by ever-increasing levels of abstraction; the use of higher-level languages, of course, but also the development of platforms, libraries, and frameworks. Professor Douglass C. Smith claims the progression of this second category far outpaced the development of programming languages.  Developers are also noticing that difficulty has shifted from designing algorithms a...
