A (presumably controversial) way to use React is to use only props never state, manage state in your own variables (possibly in a separate "controller" class) and call forceUpdate() when you have changed those variables such that

I think syscalls are not as slow as many people imagine they are, especially with modern CPUs and kernels (there are special instruction for syscalls that are faster than the old "interrupt" approach). See here: http://

In my free time I've been coding a TCP/IP stack in C++(14): https://github.com/ambrop72/aipstack . It uses a single-threaded event-driven architecture, is usable on embedded system (no mallocs), and is header

Why would you use waitForBytesWritten if you want an event loop? Just do as the note says.

Possibly so that the code corresponding to each commit builds/works, which makes bisect much easier.

(as already mentioned, ints being 64-bit does not make it any more 64-bit) It may be just a bit of hacking in the some GCC platform configuration files (I'm guessing), and getting possibly tens to hundreds of packages to work with that

The best part is how you can zoom out in your browser and you can see as much around you as you need.

It is already possible. The current test setup involves my APrinter software (firmware for 3d printers) ported to run on Linux including its web interface. It does indeed use a TAP interface and yes it reads/writes Ethernet frames (the

I don't really intend to promote this yet but anyway here's my in-progress TCP/IP stack implementation: https://github.com/ambrop72/aprinter/tree/master/aipstack It is written in C++14, is

I don't think there's really a "functional gap". All generally useful programming languages including Prolog are imperative "in the end" no matter what the books say, and anyone good at using them will think ab

From the service configuration file posted on that reddit thread, it is a WCF based service and it seems to have metadata access enabled (the <endpoint address="mex"...> part). One could try to use Visual Studio to "add

If the HW has good vectored I/O support then it might be possible to send out data directly from user buffers. This is by composing a packet using two buffer descriptors, one for the header, which points to the next descriptor for the

Please stop saying the documentation is "total mess" and "absolute shit" because this is far from the truth. There is comprehensive documentation available for Nix[1] and NixOS[2]. There is an online search for packages

Yes, with SIGCHLD you can call waitpid(-1, &status, WNOHANG) in a loop until it fails, and you will collect all terminated children.

It helps if you ever looked at the packets for example in Wireshark and have at some understanding of how TCP works. But the most important thing is the ability to read standards (RFCs).

This is great. I don't see how I can resist making one. I will probably 3D-print the hardware but use my own electronics and SW for controlling it. (I'm kind of addicted to writing my own software for controlling 3D printers and t

I am developing a new TCP/IP stack targeting embedded systems primarily. It is being written in a restricted subset of C++14 (e.g. no dynamic memory or exceptions, but virtual functions are great). There is a LOT of things complete alr

One way to solve the scaling issue is to set the external monitor to a virtual higher resolution while still driving it at its native resolution (with scaling down done in GPU). Actually Linux/Xorg generally support this out of the box

Right, this is basically what I said in my comment :) Thanks for the proposal reference.

I suspect the issue is that variant<int,char> is not trivially copy constructible (at least when I tested on godbolt), so the ABI believes it is not allowed to pass the object by value. (this is a guess only, correct me if you know be

I created a programming language called NCD. It is a mostly imperative language but where each statement can make the program backtrack to that point. The original intended use case was for configuring the network on Linux but it is really

Why would STUN be necessary if the client is behind NAT? So long as the server is not, the client can send the first packet and NATs will establish associations for the packets from the server to arrive to the client.

Obviously no, the first (for M==1) means exactly one is true, the latter at least one is true. But a1||...||aN is equivalent to bool(a1)+...+bool(aN)>0 (assuming no integer overflow :).
