Some notes on Input Director and alternatives: what about multiple platforms and mixing local plus remote access?

Posted by jpluimers on 2022/07/29

More than 10 years ago, I wrote about 7 screens; 3 computers; 1 keyboard/mouse to direct them all: Input Director and started with

At home, I have 7 screens on 3 computers on the same desk. That sounds like a clutter, but all these keyboards and mice hooked up to them add even more clutter. Until I found out about Input Direct…

In the mean time, I’ve mainly used a Mac with MacOS as a front-end to virtually logon to remote machines using both the internal display and one or two external monitors.

Especially when doing video (think Covid-19 and especially on-line meetings!) in addition to software development work, this is far from ideal.

So here are some things on my list of potential enhancements to this situation:

WhatsApp Desktop for Mac or PC cannot only chat but also voice and video call

Posted by jpluimers on 2022/07/28

Easiest way to video call from your PC via WhatsApp is to use [Wayback/Archive] WhatsApp: Download – Mac or Windows PC.

This should be an alternative for Hangouts Video Calling as Hangouts is yet another product killed by Google as mentioned in many places for instance:

Finger print as factor in authentication?

Posted by jpluimers on 2022/07/27

A finger print as authentication factor: be sure it is not the only factor, and devise a way to delete it just in case some party wants to force you to use it as an authentication factor.

Cool: [Wayback/Archive.is] eidam/cf-workers-status-page:

Will try this out in a while, hopefully before this actually reaches the front of the blog article queue (:

Some Pi-KVM v3 notes

Posted by jpluimers on 2022/07/25

Last year, I wrote about Low cost remote IP KVM and control, is it possible?, mentioned [Wayback/Archive.is] Pi-KVM – Open and cheap DIY IP-KVM on Raspberry Pi and pledged for the [Wayback – OpenSSH 8.0 release notes/Archive.is] Pi-KVM v3 kickstarter project.

From their updates a few notes and a few of my own on PoE, HDMI/VGA, video passthrough, and a short of shopping list.

First the entries from the PiKVM Kickstarter updates::

Perilex en mechanische ventilatie / balansventilatie / warmteterugwininstallatie aansluiting

Posted by jpluimers on 2022/07/22

Onze WTW moet geregeld van het net af voor onderhoud aan de filters.

Dat is niet heel goed voor het Perilex stopcontact in de muur, dus ik zocht een andere manier om het apparaat af te schakelen.

Ik ben er nog niet helemaal achter (behalve de hele groep waar diverse andere delen van de keuken en het trappenhuis aan hangen), maar hieronder het aansluitdiagram zodat ik het in ieder geval terug kan vinden.

Hier iets meer over Perilex aansluitingen en onderhoud aan WTW / balansventilatie / mechanische ventilatie:

Missing a KB article? Try the Microsoft KB Archive – BetaArchive Wiki

Posted by jpluimers on 2022/07/21

Over the last years, Microsoft has been retiring a lot of KB articles that in some situations can be of great value, not just when using legacy systems: sometimes they are the only source of accurate information on current systems as well.

I was glad to find that many of the retired articles made it to the [Wayback/Archive.is] Microsoft KB Archive – BetaArchive Wiki.

How to Configure Stack Overflow The Key Macropad? | Drop

Posted by jpluimers on 2022/07/20

In the past I joked about a Copy/Paste keyboard for Stack Overflow, and even Stack Overflow had an April 1st joke about it early 2021 (see below). Boy  was I surprised by now it actually has existed for more than half a year!

Thanks [Archive.is] Matthijs ter Woord for pointing my attention to this.

Drop actually has some nice keyboards. Now I wish they made an UltraNav one. Their selection is at [Wayback/Archive.is] Mechanical Keyboards | Recommended Products | Drop.

Converting inline svg xml to png

Posted by jpluimers on 2022/07/19

A while ago, I had a web page showing the logo as inline svg xml code.

Edit 20231209: [Wayback/Archive] Render SVG to PNG: Edit fiddle – JSFiddle – Code Playground (explained in [Wayback/Archive] html – Convert embedded SVG to PNG in-place – Stack Overflow by [Wayback/Archive] User anatoly techtonik – Stack Overflow) works way better than the InfoHeap link:

  1. Replace the svg element in it (but keep the id="inputSvg" attribute!),
  2. Run the fiddle,
  3. Save the rendered PNG file by right-clicking the “PNG (Save link as..)” link then saving the file.

Original content

It took a while to find a place to convert that on-line: [Wayback/Archive.is] inline svg xml to png – online html sandbox – InfoHeap (via [Wayback/Archive.is] Convert svg xml text to png image using canvas – InfoHeap):

The solution is a bit of JavaScript (quoted below) that you can run-online: modify the svg bit in it, then run it, scroll down in the result and verify if the canvas fits (when not: adapt the canvas side, then re-run).

The svg xml code needs to be all on one line, so remove any line breaks in it before running.

I have tested it in Chrome, but it should work in non-Chromium browsers like Firefox as well.

The inner workings of the JavaScript conversion code is explained in [Wayback/Archive.is] html – Convert embedded SVG to PNG in-place – Stack Overflow with more demo code at [Archive.is] Rasterizing In-Document SVG (thanks [Wayback] Phrogz!).
