Well of course it's not only a matter of interactive usage (even because the busybox itself shell could do the conversion). The problem are script, or worse programs that invokes commands as subprocesses (programs that maybe you don&#x

Well that would be inefficient. For each command you run the kernel has to read the file, detect that it has a shebang, parse the shebang line, and then finally load the actual executable in memory. That could be a performance problem, sinc

I mean, if wine is a problem they did basically the same thing with the WSL, especially version 1 (version 2 is just a VM, but the concept of running unmodified Linux binaries on Windows like they are native application is the same). I thin

It's not e2e encrypted, so what? It's something the majority of users does not need, and that doesn't increase security that much given their downsides. Of course for Telegram is much more convenient to not have end2end encry

Not only that. If they want to intercept e2e chats it's possible with a MITM attack, that if you control the server it's not a difficult thing to do. Of course the users if they check the keys they see they are different, but prac

Well of course, but this is a feature of Telegram. It's the only messaging app where messages are stored on the cloud. This of course has security implications, but also allows you to have a big number of chats without wasting your dev

It would be far easier to add as builtins the features that are missing to GCC than change the language, that would involve rewriting a ton of code (even switching from C to C++ they are not 100% compatible, also, they may introduce bugs di

Yes but if you work professionally as a software engineer, chances are that you don't only use your PC. Being that a server that you connect remotely to develop on, or a production system where you connect to investigate a bug, or the

I wonder why putting software on every machine, instead of relying on a good firewall and network separation. Granted, you are still vulnerable of physical attacks (i.e. the person coming with an USB stick) but I would say much more difficu

I often find out that SSH is blocked in a lot of networks. This is frustrating, since I usually clone git repositories trough SSH (and I'm considering for this reason switching to HTTPS), since I find stupid having to use a VPN just to

It's something you can do since a lot of years. I used to do so 10 years ago, when I've got the first motherboard with UEFI. But is it useful? It saves a minimal time in the boot sequence, but at what cost? The bootloader (being i

They should. The only way to make these platform disappear is to ignore them for open source project. To me the mistake of open source software is to make programs compatible with proprietary operating systems, this way people that use thes

You could have just extended the IPv4 header in such a way that the routers in between you and the server didn't need to understand the extended protocol, and could continue to route IPv4 packets as-is, since they only see the upper 32

I also used this mechanism more than one time on embedded project. Define a static variable with some metadata of the firmware and markers, such that tools (e.g. tools to perform an update) can, by simply using a regex on the binary file (t

The thing that makes me crazy is that the thing that we do on computers are basically the same each year, yet software are more and more heavy. For example just in 2010 a Linux distribution with a DE just started did consume 100Mb of RAM, a

I think the problem here is not only related to cloud environments. Is having an SQL command that writes the configuration file a good idea to start with? It's probably something dangerous, I prefer to SSH into the machine and edit the

Plain text is more easy to reason about, because we are used to process text. A good textual output, that is records delimited by spaces, tabs or a delimiter, to me is all it's needed, for most applications. An object structure it&#x27

What I don't like about Android is that you need root to have full access to your filesystem. That to me is a shame, let me have a privileges that allows me to get access to app data. The current Android permission model doesn't a

The problem is that the TCP/IP model stops at level 4, and if we consider TCP a protocol of transport, it shouldn't do that. In the OSI model what you talk about is level 5, that is session, but in TCP/IP there is no such lev

At that point why using Redis entirely? You can use any DBMS you want, either relational or NoSQL. The advantage of Redis is that it is a memory cache, if you take out the memory from it, just use Postgres or whatever DBMS you are using (I

I mean if you need to do performance analysis on a software just recompile it. Why it's such a big deal? In the end a 2% of performance of every application it's a big deal. On a single computer may not be that significant, think

It's basically saying the same thing. One thing other apps can't do on iOS is... installing packages on the system. This is only a thing that the App Store app can do. So Apple has to open up to third party the possibility to inst

I think the reason is that "a good trackpad" as well as "a good keyboard" is not something that can be measured. Let's say that the cost of a good trackpad is equivalent to the cost of, let's say, 16 more Gb of

To me the popularity of vim is also due that it's a small and fast editor to be used in the cli with more featires than nano, while emacs mostly is a gui application. This makes it ideal to edit configuration files or small scripts on
