GitHub – kzahel/web-server-chrome: An HTTP Web Server for Chrome (chrome.sockets API)

Posted by jpluimers on 2020/06/01

Cool: [WayBack] GitHub – kzahel/web-server-chrome: An HTTP Web Server for Chrome (chrome.sockets API)

This allows you to develop HTTP applications that live in Chrome:

[Archive.is1/Archive.is2] Web Server for Chrome – Chrome Web Store: A Web Server for Chrome, serves web pages from a local folder over the network, using HTTP. Runs offline.

Of course you could to python -m SimpleHTTPServer 8888 or python -m http.server 8888, but this runs within chrome and can be used from inside JavaScript projects.

Features

  • serve local files
  • configure listening port
  • configure listening interface (e.g. localhost or all interfaces)
  • custom http handlers possible
  • websocket support available
  • works nice with chrome.runtime.onSuspend
  • options for autostart, start in background, etc etc.
  • handles range requests, HEAD, etc
  • options for CORS
  • optional PUT, DELETE request (for upload files)
  • sets MIME types
  • can render directory listing
  • See relevant options: https://github.com/kzahel/web-server-chrome/blob/master/polymer-ui/options.js

Via [WayBack] This is super useful: A# web #server that runs in #Chrome! Makes it super easy to do local web dev without the hassle of setting up a complex back end s… – Jason Mayes – Google+

GitHub – dschmenk/apple2pi: Apple II client/server for Raspberry Pi

Posted by jpluimers on 2020/05/28

[WayBack] GitHub – dschmenk/apple2pi: Apple II client/server for Raspberry Pi: hybrid computer of a Raspberry Pi inside an Apple II (either ][, or ][+, or //e) so the Apple II can be a front-end to the Raspberry Pi which then can run an Apple IIGS emulator, talk to the Apple II storage hardware and much more.

It can run [WayBack] RASPPLE II: A2CLOUD, A2SERVER, Apple II Pi for Raspberry Pi

If I land a project using Zabbix again, one of the things I need to look into is [WayBack] Best android apps for zabbix – AndroidMeta.

Davidlohr Bueso on Twitter: A programmer had a problem. He thought to himself, “I know, I’ll solve it with threads!”. has Now problems. two he

Posted by jpluimers on 2020/05/27

When doing multi-threading, I’m always reminded of [WayBack/Archive.is] Davidlohr Bueso on Twitter: A programmer had a problem. He thought to himself, “I know, I’ll solve it with threads!”. has Now problems. two he

Even with the advent of multi-core architectures long behind us (multi core hardware has been in a mature state for a long time), software for it often is not.

It is not just that programmers are not ready to do it (indeed often they are not: multi-threading is hard), but also that many pieces of software run perfectly fine in a single thread.

So when you do want to implement multi-threading, think twice.

It is one of the reasons I ported a C# version of the Deadlock Empire game (written in HTML + JavaScript) to generate Delphi code and examples. I was really glad that Dalija Prasnikar pointed to it in [WayBack] What is thread safety anyway?, and also pointed to the very important [WayBack] What is this thing you call “thread safe”? – Fabulous Adventures In Coding.

That last one stresses that multi-threading has vague definitions. It will stay vague because the problems you can encounter are virtually endless. There is no silver bullet: Lars Fosdal made this really nice remark in [WayBack] Multithreading can be hard to do right… – Dalija Prasnikar – Google+:

Locking too much is even worse than locking too little. It is very easy to deadlock with overly detailed locking. Applying locking in the wrong place, can serialize threads through a lock bottleneck.

Learning multithreading is a long series of mistakes that you probably can’t avoid, even if told about them up front. You are probably best off having to make the mistakes yourself and then learn from them ;)

To which Asbjørn Heid added:

… after a while I came to the realization that recursive locks are evil. They make it so easy to “just lock everything”. In contrast, non-recursive locks forces you to have explicit “thread-safety borders” in your code. And such borders really leads to better designs.

Here are the games:

Need to look at monospaced programmers fonts again

Posted by jpluimers on 2020/05/27

At the time of looking, FiraCode would not work in Delphi but would in Visual Studio. Reminder for me to look at it again: [WayBack] GitHub – tonsky/FiraCode: Monospaced font with programming ligatures.

A cool feature of the font is that it has ligatures for common multi-character combinations like := or ...

Back when scheduling this, I was still at Lucida Console because of its large x-height and small line spacing.

It is time to revisit my font choice, so lets include at least these candidates:

Beyond console.log() – Matt Burgess – Medium

How to move Git submodule to sub-directory? – Stack Overflow

Posted by jpluimers on 2020/05/26

It’s a few steps as per [WayBack] How to move Git submodule to sub-directory? – Stack Overflow, so I’m not sure it is the best solution, but it at least works (thanks Philzen):

Had the same problem just the moment ago and ended up deleting the submodule reference (as outlined in this article) and recreating it where i wanted it to go.

To follow your example of moving submodule jquery into repos/jquery

  1. Delete the (typically three lines) submodule reference from .gitmodules.
  2. Check .git/config for references to the submodule and remove them, if existent
  3. do git rm --cached jquery to cut the submodule reference out of the repository
  4. remove the old submodule folder
  5. recreate you submodule reference (as you possibly did before) with git submodule add git://github.com/jquery/jquery.git repos/jquery

In case your submodule was set to specific tag, respectively commit (which you’ll surely have in a stable project) you will have set it again.

Due to this complex process i am strongly hoping there is (or will be, at least on the git roadmap) a more straightforward way of achieving this. If not, surely some scripts could be fumbled together to do this quicker…
