54th birthday present: The death of useful #a11y #Accessibility bots like @AltTextUtil

Posted by jpluimers on 2023/04/29

Twitter won’t be the same after today as many useful bots ran by volunteers will dy as they cannot raise the required USD 42k per month to operate.

Nice 54th birthday present Elon!

I want to check out how to do POST requests using bookmarklets in order to save URLs to the WayBack machine

Posted by jpluimers on 2023/04/27

I want to check out how to do POST requests using bookmarklets in order to save URLs to the Wayback machine.

The reason is that every few months or so, saving a page the normal way through a something like https://web.archive.org/save/URL fails for one reason or the other, but going to https://web.archive.org/save, then entering URL, and pressing “SAVE PAGE” button works fine:

The the failing way above is using a GET request, the succeeding workaround will open https://web.archive.org/save/URL  using the below POST request (where I omitted some HTTP cookies and HTTP header fields for brevity).

  • POST request using PowerShell:
    $session = New-Object Microsoft.PowerShell.Commands.WebRequestSession
$session.UserAgent = "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/96.0.4664.110 Safari/537.36"
Invoke-WebRequest -UseBasicParsing -Uri "https://web.archive.org/save/URL" `
-Method "POST" `
-WebSession $session `
-Headers @{
"method"="POST"
  "origin"="https://web.archive.org"
  "referer"="https://web.archive.org/save"
} `
-ContentType "application/x-www-form-urlencoded" `
-Body "url=URL&capture_outlinks=on&capture_all=on&capture_screenshot=on"
  • POST request using cURL on bash:
    curl 'https://web.archive.org/save/URL' \
  -H 'origin: https://web.archive.org' \
  -H 'content-type: application/x-www-form-urlencoded' \
  -H 'referer: https://web.archive.org/save' \
  --data-raw 'url=URL&capture_outlinks=on&capture_all=on&capture_screenshot=on' \
  --compressed
  • POST request using the fetch API in JavaScript:
    fetch("https://web.archive.org/save/URL", {
  "headers": {
    "content-type": "application/x-www-form-urlencoded",
  },
  "referrer": "https://web.archive.org/save",
  "body": "url=URL&capture_outlinks=on&capture_all=on&capture_screenshot=on",
  "method": "POST",
  "mode": "cors"
});

BTW: Yes, I know that URL is not a valid URL, so it will return a page with “http://url/ URL syntax is not valid.“.

All links below via [Wayback/Archive] bookmarklet post request – Google Search:

I tried to put createFormSubmittingBookmarklets/createFormSubmitBookmarklets.js in a bookmarklet using both userjs.up.seesaa.net/js/bookmarklet.html and skalman.github.io/UglifyJS-online. That failed: somehow this code does not want to run as bookmarklet.

Running it from the console is fine though, and gave me this basic bookmarklet template:

javascript:function sf(ur,ty,fd){function me(tg,pr){var el=document.createElement(tg);for(const[nm,vl]of Object.entries(pr)){el.setAttribute(nm,vl);}return el}const fm=me("form",{action:ur,method:ty,style:"display:hidden;"});for(const[nm,vl]of Object.entries(fd)){fm.appendChild(me("input",{name:nm, value:vl}))}document.body.appendChild(fm);fm.submit()}sf("https://web.archive.org/save","post",{"url":"URL","capture_outlinks":"on","capture_all":"on","capture_screenshot":"on","wm-save-mywebarchive":"on","email_result":"on","":"SAVE PAGE"});

There bold URL there is the URL to be saved. I need to test this, then rework it to become parameterised.

Special cartridges with heat-shrink tubing for dymo and brother label writers

Posted by jpluimers on 2023/04/26

Labeling cables is important, especially when you have a lot of them, and it is tough:

  1. Paper and plastic tables tend to loosen over time.
  2. Numbers or letters you can snap on only work on thicker cables and over time tend to break loose (due to plasticisers evaporating).
  3. Permanent markers are less permanent and fade over time.

Hopefully heat-shrink tubing you can print on with either Dymo or Brother laber writers will outlast 3. At least they won’t loosen like 2. and 1.

So I was glad that [Archive] Jilles🏳️‍🌈 (@jilles_com) / Twitter started a thread, which I tried to help keeping coherent.

VMware fixes critical zero-day Workstation/Player/Fusion exploit revealed at Pwn2Own

Posted by jpluimers on 2023/04/26

A less clickbaity title than most articles today as the below only applies to the VMware hypervisors running on MacOS and Windows.

The last Pwn2Own Zero Day Initiative revealed two major issues that allow a virtual machine to either execute code or read hypervisor memory on the VMware Workstation/Player/Fusion host:

  1. [Wayback/Archive] NVD – CVE-2023-20869

    VMware Workstation (17.x) and VMware Fusion (13.x) contain a stack-based buffer-overflow vulnerability that exists in the functionality for sharing host Bluetooth devices with the virtual machine.

  2. [Wayback/Archive] NVD – CVE-2023-20870

    VMware Workstation and Fusion contain an out-of-bounds read vulnerability that exists in the functionality for sharing host Bluetooth devices with the virtual machine.

Both issues have been fixed now, so be sure to deploy the fixes or, if you can’t, apply the workarounds.

So long and thanks for all the fish: PC Engines apu platform EOL (in 2024, but still)

Posted by jpluimers on 2023/04/24

It was great while it lasted, so be sure to order within the next 12 months as  [Wayback/Archive] PC Engines apu platform EOL:

PC Engines apu platform EOL
The end is near ! After a long production run, AMD will accept last orders for the SOC used in our apu2/3/4/5/6 boards by end of June 2023.
apu phase-out We will do a life-time buy for a quantity of the AMD SOC and some other key components. We are willing to schedule customer shipments through end of June 2024. There is a 26 week lead time on the AMD SOC, expect limited supply until late 2023.

First ordered, first served. Binding orders may be required for large quantities.
New products ? Despite having used considerable quantities of AMD processors and Intel NICs, we don’t get adequate design support for new projects. In addition, the x86 silicon currently offered is not very appealing for our niche of passively cooled boards. After about 20 years of WRAP, ALIX and APU, it is time for me to move on to different things.
Thank you ! I would like to thank all of our customers for their business, and sometimes patience.

Need to rethink which Windows package managers to use

Posted by jpluimers on 2023/04/24

Triggered by last week’s post Need to take a look a Scoop (as a long time Chocolatey user), I need to re-think which Windows package managers to use and in what order.

Basically there are two challenges:

  • User level (scoop) versus system level (winget and chocolatey) installations
  • Availability of packages in each package manager

Since I hardly used winget, I need to get started at Windows Package Manager – Wikipedia.

A good example of unavailability is at [Wayback/Archive] Scott’s Ultimate Tools via Winget – DVLUP (which has the ID values for winget or chocolatey of [Wayback/Archive] Scott Hanselman’s 2021 Ultimate Developer and Power Users Tool List for Windows – Scott Hanselman’s Blog)

Towards a work setup on a hardened host and doing everything in VMs

Posted by jpluimers on 2023/04/21

SwiftOnSecurity posted this interesting tweet in 2021: [Archive] SwiftOnSecurity on Twitter: “Lenovo P1 Gen3 with 12core Xeon, 64GB RAM, two 1TB M.2 SSDs. Running Windows Server 2022 with the Hyper-V role. All hardening applied to host OS, almost nothing happens here except managing guest VMs. On the second SSD I then have Win10 VMs joined to the corporate domain.” / Twitter.

I wonder if a similar setup can be done using an Apple M1 based machine as host and running all work in virtual machines.

Swift had some issues getting cameras and microphones to work: [Archive] SwiftOnSecurity on Twitter: “The problem here is Teams. If I want to pass through my webcam and microphone that could get a bit dicey, despite HyperV Enhanced Session being essentially an RDP session. For now I’m using my phone for Teams microphone. Also I’m not sure how well thermal management will work….” / Twitter

This resulted in some answers and interesting links:
