That's quite an achievement, and I'm even more impressed he was able to do so in the textile industry that suffered so much in the mid-nineties in the region. Context: I'm from the Itajaí Valley (where Brusque is located), wh

It makes zero sense to look at nationwide average for Brazil to draw any conclusions without looking at per-state or per-region data. Northern region has places with 60+ homicide rate, southern region has places with 3-4 homicide rate. Take

Nothing new on this, experienced programmers know the performance implications of data structures (ie, lists are generally bad regardless of the language/paradigm) and most complains about language itself can be read as "I'm

Generally, a big improvement in ability to focus, and a sustained mental clarity throughout the day. Entering in ketosis was also an watershed moment, like an epiphany, with a sudden feeling of increased awareness. But it's hard to des

His reading is simplistic, but so is the article: there is no mention about different metabolic states, for instance. The brain depends on a very small quantity of glucose to function - it arguably is more efficient with ketone bodies, for

The study doesn't mention this anywhere, but one can assume it considers only a state of glycolysis. This makes the the title/conclusion a bit misleading. In case of ketosis [1], the brain mainly relies on ketone bodies for fuel..

I would say it is not only valid but a very interesting method to deal with 0-day exploits and automatic scanners. I have a number of services running at home, all outside the standard ports - sip is on 5099 (remote gateway is on 5088), SSH

Sorry, but I strongly disagree. I can think of two very strong reasons to prefer awk over perl: * busybox implements awk, so its (usually) available even on embedded platforms * awk syntax is way clearer than perl, anyone that has a few exp

It's an excuse that is commonly given - but easily avoidable if you care enough about the ones that pay your salary by buying processors from your company. And not only that, but they did much more than the average Joe and essentiall

Computer Science is a science field, therefore computer scientists usually see themselves as something more than an engineer - you don't want to apply the same knowledge over and over to make something exactly as the known knowledge te

This classification of "paradigms" is a bit off. First, declarative programming is a generic name which includes a broad range of paradigms - from functional to logic programming. Logic programming is something that deserves a spe

Nothing wrong, I'd love to use taxis. But I have a few conditions: * I want to call a driver and know if the ride was accepted, if the car is coming, how much time it will take for it to arrive, all in realtime... and specially, I wan

You article about hiring a C++ developer made me chuckle on the interviewees' answers; apart from the "virus" one I've also heard all the others - and had the same thoughts. You'd think that one would prepare a bit

It's amusing to read all these calls for a more democratic EU, specially when comparisons with the USA are made. EU membership is voluntary, you can leave if you want. What would happen if an USA state decided to leave? Check the histo

How can one compare UK and US and say the later has better social mobility? Ever heard of NHS (1) or council housing? Have you compared tuition fees on both countries? While I mostly understand the different atmosphere on both places, and e

Latency and speed are two very different things. For good audio quality, the first is way more important than the later. Also, lossy codecs usually drop a good chunk of information in favour of compression, working with larger packets for b

Indeed, in the later case, exceptions are really an unnecessary cost. In fact, another argument which could be made against the use of exceptions is that the abstraction per se is not a really good mechanism for abstracting error handling.

I sometimes find it hard to discuss some subjects with some of my co-workers that don't have some degree directly related to computer science. For instance, it's very common for electrical engineers to work on software development

This seems to be a simple RTFM issue to me: POSIX specifies that gmtime() uses UTC and localtime() uses current timezone. Using gmtime() would implement the desired behaviour without any need to hardcode environment variables.

Funny how the "proper" first example still has a lot of things to be addressed, like the fact that it has a magic number (7) coming from nowhere, which is duplicated a few times as well. It would be way less error-prone to calcula

In 2004, I wrote the first article about a well-known but not very popular brazilian singer in the portuguese Wikipedia. I spent the whole weekend on it, citing references, finding dates, listing albums, etc. A few years ago I went back to
