I suppose it also immediately reveals the IP address of the receiver to the sender.

What useful meaning is there for optimization purpuses? As far as I know, there is no meaning in pointer-to-const other than it must not be used directly to modify the stored value (if it is you get a compile error). It is always valid from

I imagine "matter" as commonly understood would contain at least electrons and protons, but they would just be making electrons and positrons. Can we make protons/neutrons out of light too?

The typical strcat code you see in the wild: char buf[100]; buf[0] = '\0'; strcat(buf, "Hello"); strcat(buf, " "); strcat(buf, "World"); strcat(buf, "!\n"); The inefficiency is that eac

Huh, I never use str(n)cat, because it's inefficient by design.

Windows is supported and works, there should be no reason to add new code. The only thing lacking is a recent Windows build. However, it should be easy to build via https://github.com/Alexpux/MINGW-packages .

An alternative approach is to use my own tun2socks program [1][2], instead of tsocks. This utilizes an integrated lwIP stack to transparently expose the proxy to the entire OS. It's a little tricky to set up the network interface and r

Nix is far different than everything else you mention. It's not tied to a particular Linux distribution or OS (well, Windows/Cygwin support is shaky but nobody is stopping you from improving that). It provides a foundation (functi

Yawn, another language-specific package manager. If only there was something like a universal package manager, that provides a generic but powerful package-management platform. Something where package specifications look just like expressio

Last-access time should just die. As explained in the article it is practically useless, and it causes unneeded disk writes, making disks fail sooner. When installing Linux machine I always remember to add noatime to the mount options if it

Where does one get the patched libpng-1.6.19? The libpng site is broken for me right now.

In my APrinter firmware project[1], I rely exclusively on Nix for building for multiple microcontrollers, including AVR and many ARM ones. It's great - I can tell anyone "just get Nix (on Linux) and run this command". They c

Given the firmware source, it generally isn't too hard to port an existing open-source motion control software (which there are plenty of) to run on this machine. Electronics schematics would help but the firmware source is enough.

Surely one doesn't have to use the same certificates for the firmware verification of boot images and for the signing of Windows applications.

When I was in high school (in Slovenia), I have actually brought a home-made "bomb" to school. It had an LCD and a keypad, you would arm it and it would count down while beeping with increasing frequency, unless you entered the co

It is targeted to ARM uC's and also works on AVRs with enough RAM and program space (yes I've tested it). Write support requires a significant amount of RAM; I think about six 512-byte blocks. When compiled in read-only mode, it s

I've mostly used Wikipedia, https://en.wikipedia.org/wiki/Design_of_the_FAT_file_system . Also a little bit the dosfstools source code.

Related, I'm doing a FAT32 driver for embedded systems (fully asynchronous!). It's part of my APrinter firmware project: https://github.com/ambrop72/aprinter/tree/master/aprinter/fs Curren

I don't completely understand the description but I think they managed to extract the private key of the server.

As the author of tun2socks (which is currently used under the hood in shadowsocks-android and Psiphon3 for system-wide proxying), I wasn't even aware this effort was in progress. Very sad to see it stop.

I think the proper check is: // size_t size; // uint64_t chunk_size; if (chunk_size >= SIZE_MAX - size) { return ERROR_MALFORMED; } Due to size being a size_t and SIZE_MAX being well a maximum size_t, SIZE_MAX-

Do they have permission to use the WebGL trademark in the name? Khronos has quite some info about that, but I don't see immediately how their use fits into the terms. https://www.khronos.org/legal/trademarks/#

Does the server get the client's public key before or after the client has identified the server? I suspect it's after - which would imply that this is much less harmful than it looks like, since by then you've already confir

I don't personally care about Python packaging (and virtualenv) anymore when I can use any relevant Python package with Nix, or easily make a Nix package myself. I just hope the wheels don't make it harder to package stuff with Ni

How do you conclude that all enclaves are exclaves? A connected state that is entirely surrounded by another state is a counter-example.

by ambrop7 11y ago
Indeed. No need to use "complex" features like RAII/RTTI/exceptions. Generally, I see features like classes, overloading and templates as "compatible" with C-style coding.

I'm not sure if you're already doing this, or if it's relevant to you, but a possible way to improve performance is to allow a "window" of commands that you haven't received an "ok" for. I believe com
