  How Many C Programs Are There?

If I choose a size S, can you tell me how many valid C programs exist that are no larger than that size? I’m actually interested in the answer — it’ll help me make a point in a paper I’m writing. Shockingly, the Internet (or at least, the part of it that I looked at based on a few searches) does not provide a good answer. Let’s start with a few premises: Since it would be exceedingly difficult to construct the exact answer, we’re looking for a respe...

  How Computers Boot Up

The previous post described motherboards and the memory map in Intel computers to set the scene for the initial phases of boot. Booting is an involved, hacky, multi-stage affair – fun stuff. Here’s an outline of the process: An outline of the boot sequence Things start rolling when you press the power button on the computer (no! do tell!). Once the motherboard is powered up it initializes its own firmware – the chipset and other tidbits – and tries to ...

  Eight C++ programming mistakes the compiler won’t catch

C++ is a complex language, full of subtle traps for the unwary. There is an almost infinite number of ways to screw things up. Fortunately, modern compilers are pretty good at detecting a large number of these cases and notifying the programmer via compile errors or warnings. Ultimately, any error that is compiler-detectable becomes a non-issue if properly handled, as it will be caught and fixed before the program leaves development. At worst, a compiler-detectable error results in los...

  One of the Best Bits of Programming Advice I ever Got

Years ago (early 1992), I attached myself to this crazy skunkworks project that was using this weird language called Smalltalk. "Object Oriented" was in its infancy as a "hot" item. High paid consultants. Lots of people laying claim to what this new object religion was all about. This was 5 years before Alan Kay would make the statement "I invented the term 'Object Oriented Programming' and this {Java and C++} is not what I had in mind."Shortly after hooking up with this whacky group with t...

  7 big mistakes that make your layout a disaster

Even though the web design field has become a real industry, building a website is part art, part science. The design of a website may attract people but it may also make them run away, it depends on the work of the web designer. The experience, the talent and the capacity of endeavor are the greatest tools of a web designer, a good layout is based on all of these and, besides that, it is a very time consuming activity.Making a good layout is difficult and judging its value is subjective, a desi...

  How to optimize MySQL insert statement

For a big data system, one problem is the data access efficiency, one more problem is that the data insertion is very slow. We had a service system, the data loading process would take 4-5 hours. This time consuming operation is risky since if the program is interrupted during the loading process, it might be rerun, this will be troublesome. So it's necessary to improve the insertion efficiency for big data systems. Here we provide two optimization suggestions. 1. Combine multiple insert stateme...

  What I learned from Google - You Get Fifteen Years

four years ago I was in Mountain View, California, interviewing for a position with Google. It was an odd sort of interview.  Lots of puzzles, math-like challenges, and code.  Lots, and lots, and lots of code. What struck me at Google wasn’t the challenges.  Nor was it the office environment, the cafeteria, or the mini-swimming pool, all of which were impressive. No, what struck me were the people. All of the people I met — and I mean all of them — had this ...

  10 Technological Trends that are Affecting Life of Teachers

Technology has reached the level where people think that they do not need anybody to teach them new things. When you do not know about anything, you simply Google it and get the answer.

Let us see how they are affecting the life of the teachers:  &nbs...
