Comment: Re:Null Terminated Strings (Score 1) 729

I believe none of you actually programmed in C. A string terminated by \0 can be represented by a single pointer and an have any length. You can also easily let the string keep growing (until the allocated memory is finished.)

The problem is that you usually don't know where the the allocated memory is finished.

I understand the rationale behind the pointers like they are, but I'd still prefer if pointers could keep both address and size of the buffer. But it's too late now for such kind of redesign or upgrade.

And yes, I do code in C every working day.

I work in digital TV. It is embedded, but with quite capable processors and a lot of resources. E.g. SoC based on MIPS 3300 running at 500MHz with 256MB DDR2 at 800MHz is considered "low end" and used for cheaper STBs. Software for such system is still written in C/C++. I've seen one big company using C/C++ in combination with Java, but that made system very sluggish. And Java was only for top tier (GUI). So I don't expect that C/C++ would be abandoned soon in DTV field due to entire code base already written. But Java is also making a progress because Android will be very big player in DTV very soon, so more and more thing will move to Java, but core of the system will still require solid amount of C/C++ coding in predictable future.

Yes, it would be nice if we could get entire stack - documentation, working code, test examples, free support accounts, testing hardware, source repository access, Intel engineers payed to work on our favorite project, board of directors meeting memos and our own Santa but that is not going to happen. Documentation and some support is probably all the community would get, but that should be enough. The community usually had to work with a lot less and it was still capable of making useful code.

That was really explanatory, indeed. One idea that came to my mind: how about medical records? Medical records are used by doctors not by you*, they are kept at hospitals and they are still protected by 4th Amendment. Do you think that this brings sufficient analogy to telephone metadata? Or is it maybe that medical records are protected by some law and not by the constitution?

* In some cases they may be used by the patient, but that can be said for phone listings and related metadata as well.

And not only that, but since the map can't scroll, I'm assuming the map can't rotate either.

Very good point! During my military training, official instruction was to rotate the map as you were moving/rotating - i.e. to orientate map just as the terrain is oriented and not to keep the North on the top just because the map was drawn that way.

It is very confusing to have to rotate the map in your head even when you are walking, not to mention the effort for doing it real-time while you are driving a vehicle.

...all roofs in New York should also be painted black in winter, because damnit, it gets cold in New York in winter.

During the winter, day is shorter than night, and your house is always heated to ~70F (both day and night). Hence, your roof will radiate energy for longer period (night) than it would absorb the energy (day). And black bodies radiate energy better than white ones. Conclusion is that it is better to have white roof during the winter.

Apart from necessary technical knowledge, there is one more reason: most radical social movements has often started on technical universities.

Reason for this is simple. Technically oriented people tend to underestimate how society works, and believe that it is possible to change it easily. This attitude was also seen in XIX century, when mathematicians tried to apply mathematics rules to social problems. It should mention that this never worked. Not because mathematics is wrong, but society is simply too complex to be modeled that way. (Or, it could be modeled mathematically, but results would not be spectacular.)

Or to say it in other words: you have an intelligent but socially incompetent person, who believes that everything is easy to fix (hey, there was no WinXP that he could not attach a SATAII disk to!). He is highly dedicated, he believes that his position in society won't be appreciated as it should, and he believes that one bomb could actually solve something. Doesn't this sound like a good candidate for a terrorist?

DAB is around 30% efficient in transmission, whereas FM is about 90%.

Please define "efficiency in transmission".

This is a term from telecommunication theory. For each type of modulation (AM, FM...) you have carrier and signal which is embedded into the carrier. IIRC (it was 1997 when I attended telecommunication course), efficiency is defined as a power of the signal compared to the power of the carrier. In AM it is like 0.5% (!) which is why they have so powerful transmitters (up to 1MW, IIRC). FM is much better in that regard.

Scrum has one good point - show your code to your customer often and apply his comments. But that works only for GUI or web. I cannot imagine that in, say, medical software. For instance, one of my colleagues had to optimize crucial piece of code (some heavy math for CAT scanner). It took him several months. Only thing he could say to the customer was like "it is now two times faster" or "it is now 3.45 times faster". Not something you can really get some useful feedback on.

In another company, we were supposed to do a project for GE, and there was some serious GUI there, but their office was some several thousands miles from us and I really didn't know how we would make regular meetings with them as Scrum required. Also, they had some very elaborate specs and they did not see too much point of Scrum methodology. In some other situation, that project would be a perfect one for Scrum.

PS One thing I don't like with Agile evangelists is that Agile (Scrum in this case) is always right. It's either "what are you doing is not Scrum" or "you did not adapt Scrum to your needs", but its never the problem in Scrum.

Reference the NULL within NULL, it is the gateway to all wizardry.
