I looked at your site again and see you made changes. Stop working so fast, it's actually hurting your presentation pretty badly. I see "We make PCBs fast". I suppose it may mean s…

Love the energy, but I can hardly believe the title "Proven Metals" because your website does not stand up to basic scrutiny: 1) First issue: I do not know what your manufacturing …

I run in LAN/Developer Mode on the X1C and P1S and I sync filaments just fine. I don't monitor my prints with my phone but if I wanted to I wouldn't complain about the lack of Bamb…

Depends on the quality of the solder joint. Poor quality solder joints do not survive mechanical shock. If you are fighting a GND pin that sinks a lot of heat, using leadfree solde…

Pipes and named FIFOs are easy and great. I say this after implementing various IPC methods (unix domain sockets with fd passing, POSIX message queues, 0MQ, XML RPC, local TCP sock…

Can anyone explain to me the advantages of Pikchr over dotfiles?

Any reason why the first example (subtracted sphere) is rotating off axis or possibly has bad geometry?

Safe string manipulation never exceeds the bounds of the buffer. So negative values are dangerous, as all as any additions that would exceed the maximum size. Negative lengths are …

You're explanation is not inconsistent with my proposal, but you don't seem to grasp VALIDITY.

If you have studied Computer Science, you should know that the null string is quite a valid string. Let's take strstr, which finds a matching substring needle in a haystack string.…

Is it more sensible to cat 2 strings, but cut off the second one, then pass off the result as valid? I would say let an INVALID string be length 0. Then accept that catting a valid…

I don't understand the fallibility. Clearly misuse of string functions is epidemic. A propagating INVALID string result makes it very clear there is a logic error and not an exploi…

Please support your argument against correctness by providing an example where an INVALID string as input to a suitable modified generic string function would result in a valid str…

NULL is the lack of any string. If one view a string as a result of an operation, then an INVALID string is the consequence of bad input to an operation.

Propagating NAN is an elegant method in floating point and makes sense for well defined string encodings like UTF-8. memcpy and company are strictly for raw unencoded buffers.

Efficiency looks past current deficiency. We have the empty string: "\0" We have the null string: NULL There is no concept of an INVALID string, as float has NAN. This would be the…

I tried really hard to find a main() function browsing the demo source code, but I could not. I also find it interesting that code boilerplating is called out as a problem, but I r…

Choose the size representation that bests fits your use case: // Put this in header to help user calculate allocation needs but hide size from user size_t LIBNAME_alloc_size(param1…

If your strings are > 65535 bytes in length, consider buffering the string data or using another data structure.

Pet pig owner here. Pigs are problem solvers. Pigs are optimizers. The following videos of my pig demonstrate this. Video 2: Pig is first learning the task. Video 3: Pig has slight…

Why use this library when similar libraries implemented in C have been in production for decades?

Ever used OpenSCAD? Try doing CSG operations with CGAL on complex STL surfaces. Then take those same surfaces with vtk, use their boolean operations. Faster but with significantly …

Sell me: I am a crusty old C++ programmer who started numerical and geometric programming on an SGI machine at the turn of the century. I have seen many academic and commercial 3D …

Yeah your intuition is correct here. On an MSP430 (which is were I use it) the producer is in interrupt context but as a savvy redditor pointed out, I will need to enable/disable i…

I'm running it on a system with 512 bytes of RAM and multiple queues...saving 1 byte helps. I do not need extra space for synchronization; I can enable/disable interrupts without e…
