If we were to somehow perform a Principal Component Analysis on the amorphous, contradictory mess of "hippie ideals", we could probably distill them down to something like a call to implement a post-scarcity, socialistic society w

I'm a bit confused here. >> Most operators in C++, including its memory allocation and deletion operators, can be overloaded. Indeed this one was. Okay, well, firstly - the issue here seems to be a problem with the implementation

The C++ delete[] operator doesn't take a size parameter either. This is neither here nor there, and unrelated to the problem the blog post is talking about.

The main reason is the object-relational impedance mismatch[1]. Basically, programmers like working with objects that have data fields. This is because most modern, widely-used programming languages treat objects/aggregates with data

The practical difference is that with async I/O, there's less overhead because you don't need a separate thread for each blocking I/O operation. It's the difference between using a single-threaded event loop to dem

k, along with j, is also often an index. Of course, this mathematical convention carried over into programming as well, with i,j, and k serving as index variables.

The "lone genius" is somewhat of a myth, but also has a certain amount of truth to it. For example, Einstein was certainly a lot smarter than the average person - indeed, probably a lot smarter than most highly-accomplished scien

Ethics aside, at a certain point, you realize you can make a lot more money legally and legitimately using your technical skills than through any sort of "clever" technical scheme that involves hacking odometers or scamming people

Okay, well - never knew this. But that example seems really cherry-picked. Many NY street names are just numbers, even in other boroughs outside Manhattan. Many streets in the Bronx are just a number (130-something street to 230-somethin

I've lived in NY my whole life, but am not familiar with this stereotype about unpronounceable names. Apart from Kosciuszko there aren't too many difficult to pronounce names of bridges/tunnels/express-ways, etc. Kosci

Basically, the main problem with signalfd is a problem with the Linux implementation of signals in general: if your program requires some kind of logic where each individual signal delivery somehow "counts" in some way, you may ru

People talk about Marx as if he wrote some kind of blueprint for a Communist state. But he really didn't. He was basically writing a philosophy of history centering around a problem he observed - he wasn't necessarily writing

Obviously the DRPK stands no chance of tactical victory in any sense. But they have a very good chance of just saying "fuck it", and causing arbitrary damage and mass civilian casualties on the order of dozens of September 11 att

That's a subjective value call. It depends on how many North Koreans are being brutalized/dying right now. We don't have that number, but it's likely that tens of thousands of the hundreds of thousands of political pri

The assessment predicts: "Tens or hundreds of thousands could become casualties" ... in the event of an all-out DRPK/(US+ROK) conflict. One factor to consider here is what happens if no conflict occurs? In that case, there

Doctors rely on software a lot to do their job. One day they may even be replaced by software.

I agree - I think for the most part, Java is a simple language that has straightforward C-like syntax. The main problem is specifically the boiler plate class and static main method you need to blurt out just to get anything even compiling

ECMAScript is a general purpose programming language that, historically, just happened to be made specifically for the purpose of standardizing a language made specifically with a web-browser (Netscape) in mind.

Some upper-scale restaurants charge you a "no-show" fee, using the credit card used for the reservation. Maybe airlines could do this? (Of course, the difference is that restaurants don't receive the actual payment for se

Good article. But I have to ask for clarification for this statement: "Empty seats cost the airlines money, and they need to recoup those losses somehow." What does this mean? The issue here is overbooked seats. If a seat is

Of course C doesn't map to all that. Neither do most of the MIPS emulators they actually use to teach MIPS assembly in universities. But it does map pretty well to basic loops/conditionals and other intro-to-programming stuff.

Yeah, automatic static reflection for serialization of standard-layout structs in C++ would certainly be nice. You can achieve something like that with std::tuple, but it's certainly not comparable to first-class serialization. PS, I

As a child, I remember walking into a "World Computers" retail store and seeing a Commodore Amiga running some graphics demo. I was utterly blown away. It was far beyond what I had ever seen with a home computer, which at that p

While I kind of like D, it's hard to really make the case for using it. The thing is, it simply doesn't provide that much of a significant advantage over modern C++14/17 to make it worthwhile. At least Rust introduces an

I know - I'm being facetious, but really, if you want to really understand how most modern computers actually work, there's probably no better way than to learn C. It's high level enough and provides enough structure so that
