It checks your shell scripts, either on-line or off-line (brew install shellcheck for Mac, apt, etc for Linuces)

Using Delphi nextgen compilers … https://xkcd.com/303/ some arguments to have both for the Win32 platform
Posted by jpluimers on 2017/03/08
It resulted into a nice thread of strengths and weaknesses of the classic and nextgen compilers.
I’m emphasising a long term wish for the Win32 platform to have two compilers: a classic one and an LLVM nextgen one.
Reasons include this:
- Various compiler architectures can emit code for the same end-platformm: Kylix Linux x86 support uses the classic compiler, new Linux x64 support is using the LLVM nextgen compiler
- Debugging non-Win32 (x86 on Windows) is slow and buggy at best
- LLVM nextgen compiler takes about 2 orders of magnitude longer than the classic compiler
- the classic compiler has various optimisation deficits for about 2 decades and won’t be fixed
- the LLVM nextgen compiler has many more optimisation opportunities than the classic compiler
- the LLVM nextgen compiler supports zerobased strings and ARC which are almost impossible to debug because of the debugger issues so writing truly cross platform code using Delphi is a drag
So, please please please Delphi team: provide an LLVM nextgen compiler for the Win32 platform.

node.js – a nightmare to get started. Did I try the wrong technology for my problem?
Posted by jpluimers on 2017/03/08
Most of my web-stuff is on Apache. Which works fine, has TLS/SSL enabled, etc.
But I wanted to do server-side JavaScript. Which somehow is a forrest without trees, or a nightmare to get started, especially on OpenSuSE.
First of all, virtually all examples explain how to run node as a script. But none explain where to save it, how to run it as a service (and restart when it crashes: it will crash) or how to run multiple sites under it. And the scripts seems to listen to a TCP port by themselves so they operate as a full server by themselves. Nice for a fully fledged portal, but not for some one-offs.
Some links below hopefully will get me re-started later on, but for now, I’ve given up: the out-of-the-box experience is totally non-intuitive.
Maybe what I really want is something else: I want JavaScript stuff that normally renders a page in the browser through the dom to run server side so I can run XMLHttpRequest to various places without bumping into CORS stuff but still render a page DOM.
If you know a better way to do what I want (serving small mostly single-page scripts written in an easy to debug/trace language) let me know.
So basically work around this:
XMLHttpRequest cannot load http://myApiUrl/login. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'null' is therefore not allowed access.

Some links on deciding if and storing your timestamps as UTC and time zone handling

Some links:

On job interviews; both on interviewing and being interviewed
Posted by jpluimers on 2017/03/07
Two interesting blog entries to read for both sides of the interview:
- [WayBack] Hello, I am interviewing people… – The Isoblog.
- [WayBack] Programmers are confessing their coding sins to protest a broken job interview process | The Outline“Whiteboard” interviews are widely hated. They also discriminate against people who are already underrepresented in the field.

raw.githack.com – like rawgit.com but supports bitbucket as well and runs on plain nginx
Posted by jpluimers on 2017/03/07
Found out recently that next to rawgit.com there is also raw.githack.com which contrary to the name also supports bitbucket files:
- [WayBack] raw.githack.com serves raw files directly from GitHub or Bitbucket with proper Content-Type headers (with Media-Type values).
- [WayBack] github.com/neoascetic/rawgithack
- plain nginx
- [WayBack] RawGit served raw files directly from GitHub with proper Content-Type headers.
- [WayBack] github.com/rgrove/rawgit
- requires node.js and express.js

bash – how do I list the functions defined in my shell? – Stack Overflow
Posted by jpluimers on 2017/03/07
Nice: “you can get both aliases and functions with compgen -a -A function”
It uses the compgen completion generator. Simply brilliant (:

Generate Mozilla Security Recommended Web Server Configuration Files

In case you manually want to configure or have a web-server that’s not supported by certbot for letsencrypt (yet): Generate Mozilla Security Recommended Web Server Configuration Files.
At the time of writing, these were supported by the generator (* were not supported by certbot for letsencrypt yet):
