This is a distraction from the post. But the thread may attract minds who are glad to correct. The post shows an example where code calls into shared-object files from picolisp. Something I have been wondering: why are the inspection option

The source is about road use, which is more specific than your claim. The top modes of transport are walking, the underground, long-haul rail infrastructure. I think the source goes against both your claim and its own headline. Diagram 3.11

This is broken. (Woke from a sleep, face-palmed. I have been in Windows IPC land and got my wires crossed, sorry.) In linux you can select on both the stdin fd and network sockets in a single call. There is a way to get a fd for AIO also. A

Try the Pieter Hintjens psycopath book. Overlook that he uses a non-clinical use of the word psycopath. Pretend he instead wrote vampire, and read for the content. He gives strategies that do not involve leaving, and that seek to build you

In the UK, Australia and Canada, courts award costs. This usually goes against the loser, but might not if the judge believes the winner held a correct but frivolous position. It seems to be a pretty good mechanism. In particular, it does n

It is not a complete match. A quality of the actor concurrency model is unreliable message delivery. The system described in the post could be done with reliable delivery expectations.

I don't think you can teach it well except through starting with C. Berkeley sockets is a weak API that became a standard. And you need to know what is happening at the C layer in order to reason about what is going on. People who know

Not to disagree with you, you highlighted intended use for linux. It touches on something i have wondered about. How far you could get in creating a general purpose computing platform with no floating point support at all, including no soft

When you hire a junior developer, they are themselves a project. How else could it be? The need for mentoring is what makes them a junior. If they didn't need mentoring, they would not be a junior. Code reviews are a reactive exercise.

I have not yet done detailed study, but your paper appears to be a fabulous resource. The context from your post is high-value also. Thanks.

There is a certain difficult to describe joy about tight native development. Ignore the haters, congrats on your release.

Where are the main blowouts in python performance? For example, is it compilation, evaluation overhead, or memory management?

You introduce a strong point with the issue moving structs over the barrier. When I do it, I create constructor functions in C, and only send pointers over the bridge between the non-C and C. I'm happy to do this, but recognise that it

"To test C code you need to compile it" I think nickpsecurity has introduced two ideas, and you are only countering the more complex one. The ideas were, * Use python as a preprocessor * Use python to call into C. To the first ide

A fun problem I play with sometimes: eek out a small-but-super-powerful subset of standard shell tools (sh, awk). For example, if you could create a forth in a dozen lines of bash, then you could just recreate it whenever you needed it. The

Western tonality has some rules. Composers can operate outside of that if they want. With computers, a single composer could make up a new set of rules for every piece. You can turn a drum beat into a note by accelerating the wave form, inv

People in this thread might be able to offer me advice on a project I have open. I know C but am not experienced working on large C codebases. Below I will describe its rough build structure. I hope for strong tool or re-framing advice. I h

You don't have mining in proof-of-stake. (Mining is for proof-of-work.) My focus is multiple-host, centralised async systems. I think this is the future, and that databases will be marginalised. Comment here elsewhere gives more detail

(I'm explaining the dream here. If I knew what I was talking about, I would have done it.) If the blockchain community gets the contract/language issues sorted out, a small dev team could knock out a first-stage system like the fi

It is misleading to describe etheteum as Turing-complete. If it were, an infinite while loop would soon crash the network. (As mentioned in the article, the processing of Ethereum contracts is powered/funded by a finite valuable curren

It is not helpful to scatter snarly phrases like "if you did your research". Also here you have created a straw man argument by introducing ideas that are tenuously resulted and then criticising the parent as though they had taken

I am using python to wrap Windows-C this week. I tried Idle again for the first time in years. Its text navigation is nasty, and caused me to go to shift editor. For example, ctrl+shift+arrows highlighting is something I do all the time and

Is the RiscV community seeking to create a bus standard? By analogy, the pc architecture is not just about the amd64 instruction set, but also PCI. I expect that broader standardisation would make life easier for operating system efforts, b

I introduced Qt because it is an example of a high-quality, full-system framework that you can chose to live in. I did not mean to imply that SDL used Qt, but I can see how it reads that way. When I was following Handmade Hero, some of the

"It needlessly restricts your platform though" Not necessarily. Casey discusses this issue well into his series, but it would be twenty or thirty hours in. There are two general approaches to multiplatform. Approach 1: the SDL way
