What amazes me most is the cascade of reasoning. It's the most obscene misuse of logic, that might be fine only if it comes from a toddler. "criticising protesters" leads to "support militia", that leads to "su

In a world where all the electronic devices are composed of x86 cores and/or have a data and/or instruction cache, it could be true. But there are plenty of architectures out there where space-time tradeoffs (by optimized compiler

> good or bad I think the question, although genuine, has a flaw, that is, reasoning in terms of "good or bad". "Good or bad" for whom? Is something that is "not good" inherently "bad" and vicevers

If I put you in front of a wall full of numbers, and I tell you "point a number with your finger and remember it", what is your finger? A number? Or the thing you use to point a number?

pointer != address Unless there is no difference between a pointer and an address , in a register you can store an address, maybe the address of a pointer (and so on). But you can be right if we talk about some registers that always poin

A variable that is a pointer occupies space in memory. In that memory (the pointer of the pointer) is stored the number. char* ptr = (char*) 0x80000000; By doing `&ptr` you can know the address of the pointer `ptr`. In that add

If you declare a structure of unaligned size, the compiler might (probably must) introduce some padding bytes at the end of the structure to fit the alignment. In some architectures you cannot do unaligned accesses (ARM for example). Unless

I think the real difference comes with the knowledge the person is carrying when learning C. For example, people that are familiar with concepts like classes, string objects, arrays, etc. brought from higher level languages are the ones tha

But what is an array anyway? It's just a bunch of (contiguous) memory. That bunch of memory has to start somewhere. Since an array is just a bunch of memory, by pointing to the beginning of that bunch of memory you are pointing to the

Some sites make you download the PDF instead of showing it in the browser. The new tab opens and closes immediately after fetching the URL, so you don't get to see the URL in the bar. If the browser is set to open files with known edit

I know. You have to set the browser to ask what to do for every download. Then you download the PDF. After that go to "downloads" and right-click and select "copy source URL" or something like that. That's the only

But they "take issues of security extremely seriously"... Typical. When are we going to get tired of the same PR, damage-controlling, bullshit that we all know are blatant lies? EDIT: we need a GDPR hero.

This is correct, and applies (and is helpful) to many cases. But the moment you need to shift an "Int", or do bitwise operations or transmit it in a network packet (think about endianness, etc.), is the moment you may regret that

The article kind of lost me at the first example. struct{ char x char y; }a; memset(&a, 0, sizeof(char) * 2); What does the compiler know about memset ? Why it should? It can be a function called heyLetsFillTheMemo
