PoE to ethernet + micro USB converters

Posted by jpluimers on 2020/11/06

The first is 100mbit, some do not get it to work with Raspberry Pi 3B+, but others do get it to work, even at 1Gbit:

The second is 1Gbit, about 40% more expensive, but just works:

Via: [WayBack] Thread by @Nick_Craver: “Shout out to @mstum for reminding me 1Gb PoE USB splitters are completely viable for Raspberry Pis – now running a fi PoE switches and using just 1 outlet on the UPS: … Less wiring and if the network’s […]”

Register and use a custom clipboard format in Delphi – twm’s blog

Posted by jpluimers on 2020/11/05

Cool post: [WayBack] Register and use a custom clipboard format in Delphi – twm’s blog.

It is about transmitting GPS (WGS 84) coordinates from one program to another via the clipboard.

One day I will find some time to dust off some draft clipboard posts that I have been dormant for too long.

These already got published:

Via [WayBack] I just now had the need to transmit GPS (WGS 84) coordinates from one program to another. First, I simply copied longitude and latitude separately using… – Thomas Mueller (dummzeuch) – Google+

Git history in Visual Studio Code

Posted by jpluimers on 2020/11/04

Out of the box, Visual Studio Code does allow you to pull from and commit/push to git repositories, but it has not much more git support.

These two marketplace extensions will help big time:

I like GitLens most as it covers so much more than just git history.

If you only need git history access, then you can use Git History as well.

More information and a better comparison:

Pointers are dangerous – twm’s blog

Posted by jpluimers on 2020/11/04

TL;DR

  1. Do not keep pointers to objects in memory that can be relocated.
  2. SetLength can relocate the memory

Via: [WayBack] Pointers can be really helpful, especially they can improve performance and readability, but they are also dangerous. I spent nearly a day tracking down… – Thomas Mueller (dummzeuch) – Google+

Plastic SCM blog: Unified diff of a branch

Posted by jpluimers on 2020/11/03

Too bad I bumped into this a long time after having been a regular PlasticSCM user: [Archive.is] Plastic SCM blog: Unified diff of a branch:

Learn how to create a custom action to run a unified diff operation for a Plastic SCM branch.

It is an open source tool called unifiedbranchdiff.exe at github, and seems based on a cm path for getting paths, and cm patch for generating the actual patch, and needing external GNU tools diff and patch (hopefully it also works with more recent versions than the woefully outdated 2007 Win32 versions of [WayBack] DiffUtils 2.8.7 for Windows and [WayBack] Patch 2.5.9 for Windows).

html – Is it possible to specify a starting number for an ordered list? – Stack Overflow

Posted by jpluimers on 2020/11/03

Since I keep forgetting this has been possible since the introduction of html 5: [WayBack] html – Is it possible to specify a starting number for an ordered list? – Stack Overflow:

If you need the functionality to start an ordered list (OL) at a specific point, you’ll have to specify your doctype as HTML 5; which is:

<!doctype html>

With that doctype, it is valid to set a start attribute on an ordered list. Such as:

<ol start="6">
  <li>Lorem</li>
  <li>Ipsum</li>
  <li>Dolor</li>
</ol>

Since Delphi still does not include a TDateTimeHelper: use the one by colini which has tests

Posted by jpluimers on 2020/11/03

These are quite OK: [WayBack] GitHub – colinj/TDateTimeHelper: Helper record for TDateTime type in [WayBack] DateTimeHelper.pas with DUnitX tests in [WayBack] TDateTimeHelper.Tests.pas.

Via: [WayBack] Does Delphi XE 10.2.2 ship with type helpers for TDateTime type? Or do I need to implement my own. – Graeme Geldenhuys – Google+.

It got even promoted at [WayBack] Delphi XE3: Record Helpers for Intrinsic Types.

Thread by @doctorow on the RIAA using DMCA section 1201 to ban youtubedl from GitHub

Posted by jpluimers on 2020/10/31

A very interesting thread by @doctorow:

Late last week, the @RIAA sent a legal threat to @Github, claiming that the popular (and absolutely lawful) tool #youtubedl (which allows users to download Youtube videos for offline viewing, e……

More on section 1201: [Wayback] Pluralistic: 24 Oct 2020 – Pluralistic: Daily links from Cory Doctorow: RIAA kills youtubedl

There is also a great technical analysis at [Wayback/Archive.is] Analysis of the RIAA claims against youtube-dl · GitHub

This write-up follows the code paths in youtube-dl that get executed when you try to run it based on the claims of RIAA has put forward. This is a technical analysis, not a legal one.
