That is a nightmare. You are telling me that the size of the stack of a function now depends on the fact that I modify an argument? Also, you are masquerading an access trough a pointer as a direct access to some data. An access trough a po

> The code the compiler generates must have the same final result, but it doesn't have to actually work the same way. It doesn't, but when it comes to debugging, it would help to have them similar.

Also compilers nowadays are smarter and can perform link time optimizations. Meaning that if of a library you only use a single function, in the final executable you would only get that single function. In reality code that use static linki

A modern smartphone has more RAM than most computer that people use to do actual work. I mean I see around a lot of people that uses computers with 4Gb of RAM, and the standard nowadays is 8Gb for Android phones. Even with disk space, nowad

To me that is an argument that doesn't make any sense, at least on Linux. It could make sense if we talk about Windows or macOS, where you typically install software by downloading it from a website and you have to update it manually.

Or we should stop thinking about processing packets with hardware. Does it still make differences these days? Designing hardware for a single purpose most of the times is not a good idea. That means that you are stuck with the implementatio

4096 can be too much for unstable connections, for example Wi-Fi or mobile. Also, 4096 bytes at what level? Layer 2? And when you are using a tunnel, you add bytes and thus have to go higher than 4096 or go lower and reduce MTU, or fragment

All of this is true, IF you assume that you want Unicode string. That, especially on system/embedded software (the kind of software that Rust is targeting) you don't really care about Unicode and you can simply treat strings as ar

It's not the same as third party cookies! Third party cookies works only if: a) every site you visit loads some Google/Facebook/whatever JavaScript to track you. That are not all sites. b) you didn't disable these script

That code is ugly anyway, something I would have wrote in middle school... why not: function check(x) { return test1(x) && test2(x) && test3(x) && test4(x); } Or, since I assume is JavaScript, ju

Depends on what you are doing. Init scripts where simpler because the boot process was well defined, meaning that you had all your scripts in rc.d that were executed in that particular order. Now with systemd is more difficult to have somet

Well, never seen any reason to use -a or -o. To me they are less clear and you are prone to error. I find things like: [ "$a" = "$b" ] && [ "$c" = "$d" ] much more clear.

You can have other shells that are not bash, true. But you are guaranteed to find a bash shell in any Linux distribution (well, except minimal distros like OpenWRT or Alpine Linux that for saving space use busybox). Let's say that in a

For small scripts, bash is still the easier way to go. Other programming languages are not that immediate to do simple things. How many lines of code take piping a command into another in python, for example? Also bash is not portable, but

For desktop computers it makes sense. I find that hybrid hibernation gets the best of the two world. I can have the PC in sleep and have it turn on faster, or if the PC looses power you don't loose anything. A thing that I do often is

You can make it a static binary and thus make it portable on all distributions that have a minimum specified kernel version. Or you can use formats like AppImage that are designed to encapsulate a program into an image that can be run as a

We have to distinguish websites from web applications. Websites have no reason to use JavaScript. They should be a collection of documents, possibly generate dynamically on the server side, but to the user HTML+CSS that can be viewed in a b

There are many reasons why having SPA and rendering your site on the client is a bad idea. First, you are basically breaking the concept of the web, a collection of documents, not a collection of code that must be executed to get a document

Why having paths in a production binary? I mean, for debug binary kind of makes sense, but for production doesn't make any sense at all. As I understand even stripping the binary doesn't solve the issue. This is not only a privacy
