Interesting that on Linux Unix Domain Sockets are not faster than TCP. People often say that the TCP stack overhead is high but this benchmark does not confirm that.

Ah, I misunderstood, thinking that your cousin lives close to your aunt. I was suggesting that somebody physically close could do the video call.

This is unsafe (glob injection). Never use bash unless you know exactly what you are doing, and even then, better don't. Even worse to recommend bash to somebody who already stated that they don't know what they are doing. Just us

I don't understand your point. If you construct scenarios where the subprocess you call daemonizes and outlives your program, then there of course there isn't any convention your code should follow because your code isn't in

Ask your cousin to visit her and video call you together? Or go there for a weekend and check?

> no existing code working like that That doesn't really matter for discussing how correct code _should_ be written. Also, a good amount of existing code works like that. For example, if you `with open(..) as f:` a file in Python an

Thanks for your answer. That sounds good on power. My first "connection" question was about Internet connection though. Can you get e.g. 10 Gbit/s, and is there a traffic limit?

Why not a simple solution: 1. Programs should call close() on stdout and report errors. 2. It's the job of whomever creates the open file description to fsync() it afterwards if desired. 3. If somebody runs a file system or hardware th

> close a file (which ironically is the poster child for RAII) Yes, I call this "RAII is a lie" (T-shirt pending). Closing file descriptors is univerally used to showcase RAII, but it should never be used for that. C++ has the

What connection deal do you get for that? Does it have uninterruptible power supply?

Indeed. Most countries' driving laws for good reason demand that you must maintain enough distance to the vehicle in front of you so that if it hard-breaks surprisingly for _whatever reason_, you will not touch it. Lots of people ignor

Such hack is often not necessary. Set larger kernel TCP send and receive buffers and enable BBR congestion control. Speed will usually be good also across high latency links, and no multiplexing logic needed. Especially if you control both

It means exactly that, 23 mins on a single core for 10k lines! (Insert "This is C++" Sparta image here.) It is quite clean application code but it _uses_ some of the most template heavy open-source libraries around (e.g. Eigen, CG

The Haskell LSP crashes less often now than 2 years ago. It isn't perfect yet, but pretty usable for us.

Because it offers composable configuration. With Docker or Ansible you usually get a "snapshot" of a system where you can't easily and automatically change the implementation details from outside; you would have to run some u
