Really cool not too long read: [WayBack] I am in love with colors and design – UX Planet:

How to improve human experience through color

Binary search for finding problematic versions: install a specific version in homebrew and git bisect

Posted by jpluimers on 2020/04/14

I’ve used these excellent posts to find out which youtube-dl version started to exhibit troublesome NPO downloads, then later find the actual failing commit:

Why the effort? I needed an as recent as possible youtube-dl working on as many sites as possible because of some work preparation.

The first link is very important because brew versions and alternatives have stopped working some 6 years ago, even though they turn up high on Google searches for brew install specific version. Hence the quote from the first link:

Installing software packages on Mac is very easy with homebrew. You typically get the latest version, however often in production you do not have the latest version of a software package. Another use case is when you upgrade to the latest and you find out there is bug which blocks you doing something. In this case you would like to downgrade to the previous version until the bug is fixed.In both cases you need to install a specific version of a software package with homebrew on your Mac, which tends to be not that trivial. There is a lot of discussion about this on stackoverflow but some of them are outdated based on brew versions which is not available anymore.

Create a large file filled with zeros on Linux – twm’s blog

Posted by jpluimers on 2020/04/13

Interesting read as there are at least 3 options of which I only knew the first (dd): [WayBackCreate a large file filled with zeros on Linux – twm’s blog.

  • dd (fully allocated storage; zeros, random or another data source)
  • truncate (sparse storage; always gets zeros)
  • fallocate (fully allocated storage; always gets zeros)

Bug Finder, A Real Win32 Extensible Passive Debugger – CodeProject

Posted by jpluimers on 2020/04/09

On my research list is [WayBack] GitHub – DareDevil73/bug-finder: Windows passive debugger.  with an article at [WayBack] Bug Finder, A Real Win32 Extensible Passive Debugger – CodeProject:

The Bug Finder is a real Win32 debugger, entirely written in Borland Delphi, which analyzes your application execution flow, so you can:

  1. Catch exceptions on the main executable, external DLLs, primary and working threads.
  2. Produce a detailed stack trace about each exception.
  3. Place a symbolic breakpoint to get, in place of a program debug break, a full stack trace log message (dynamic tracing).
  4. Produce detailed and rotative log files for a batch application behaviour inspection.
  5. Capture output of OutputDebugString API to log file (to provide extra debugging information by yourself directly into your code).
  6. Trace Process, Threads and DLLs activities.

I found documentation at [WayBackDareDevil73 … docs, but the binary dependencies and installer are on SourceForge (where the project was originally located) and CodeProject which cannot be archived so I will look into that when it pops to the top of my research list.

Hashes and their uses – The Isoblog.

Posted by jpluimers on 2020/04/09

A nice introduction to [WayBackHashes and their uses – The Isoblog covering:

  • Checksums
    • Digit sums as simple, weak checmsums
    • Better checksums: ISBN-10 as an example
    • Proper CRC checksums
  • Hashes for storage
    • Building dictionaries
    • Breaking dictionaries
    • Handling collisions
  • Cryptographic hashes

Delphi: OldCreateOrder in inherited TDataModule might suddenly become True

Posted by jpluimers on 2020/04/08

Interesting observation that might have been in Delphi for more than a decade: [WayBack] Found something strange in Delphi again which I’ve been trying to fix for days until I discovered it’s probably a Delphi issue… – Stefaan Lesage – Google+.

I think the summary is that if you have inherited TDataModule instances, then the descendant will always have OldCreateOrder set to True.

It is reported as RAD StudioRSP-20016 TDatamodule.OldCreateOrder always resets to true on descendants, but it is present in at least Delphi 7, so likely is in the old QC database:

Uwe Raabe:
I can track this error down to Delphi 7 (really)! Cannot check Delphi 6, but Delphi 5 just doesn’t have that property.
The reason lies in TDataModule.ReadState where

FOldCreateOrder := not ModuleIsCPP;
is set.

These might be related:
