Last year, I answered [Wayback/Archive] javascript – Bookmarklet to append a string to a URL – Stack Overflow (asked by [Wayback/Archive] Karlo Guidoni Martins, thanks!).
It is about not being able to run bookmarklets on pages hosted by for instance:
gist.githubusercontent.comraw.githubusercontent.com
GitHub is an exception, as RAW files from these services do work fine:
At first sight, when running a Bookmarklet on those RAW GitHub served pages, you do not see an error: it just looks like the Bookmarklet does not work at all. The last part is right, but in the Chrome console you can actually see the error.
That error lead me to my answer:

Be careful phrasing reg.exe commands.
Sometimes it gives you the error ERROR: Invalid key name.
The reason is that the reg.exe is really sensitive on the order of the command-line: the first argument must be a full key, optionally prepended by a computername.
Any other optional command-line option (like /f to force execution without asking) needs to go after that.

I had speedtest-cli running on MacOS and various Linux machines, but not yet on Windows (see for instance my post Ubuntu: Fixing the myserious “Failed to stop apt-daily.timer: Connection timed out”).
[Wayback/Archive] Install and Test Internet Speed with Speedtest CLI Command Line – NEXTOFWINDOWS.COM reminded me there is a Speedtest CLI for Windows download at at [Wayback/Archive] Speedtest CLI: Internet speed test for the command line, but I am a an automation/scripting/devops person, so luckily there are also [Wayback/Archive] Chocolatey Software | Speedtest by Ookla (don’t get [Wayback/Archive] Ookla.Speedtest download, as that is the GUI version).
Both the Chocolatey and winget packages are named the same, so that is quite confusing. This is how I have set them apart:

For tomorrow’s post Ookla speedtest CLI for Windows has some undocumented arguments to accept license and GDPR I neede the full path to the speedtest.exe which I had installed using Chocolatey.
I know chocolatey uses a shim that redirects to the actual executable, so a simple where speedtest.exe would not cut it.
My guess would be that the generated shim allowed to either get the target pathname out, or have the target pathname encoded in it.
Luckily the first applies: a few of the shim command-line parameters are in [Wayback/Archive] Chocolatey Software Docs | Executable shimming (like symlinks but better):
You pass these arguments to an executable that is a shim (e.g. executables in the bin directory of your Chocolatey install, not choco.exe):
--shimgen-help – shows this help menu and exits without running the target--shimgen-log – logging is shown on command line--shimgen-waitforexit – explicitly tell the shim to wait for target to exit – useful when something is calling a gui and wanting to block – command line programs explicitly have waitforexit already set.--shimgen-exit – explicitly tell the shim to exit immediately.--shimgen-gui – explicitly behave as if the target is a GUI application. This is helpful in situations where the package did not have a proper .gui file.--shimgen-usetargetworkingdirectory – set the working directory to the target path. Useful when programs need to be running from where they are located (usually indicates programs that have issues being run globally).--shimgen-noop – Do not actually call the target. Useful to see what would happen if you ran the command.
But the below dumps show more more (using [Wayback/Archive] Strings – Windows Sysinternals | Microsoft Docs, [Wayback/Archive] clip | Microsoft Docs and post-processing in [Wayback/Archive] Notepad++).
Back to the second solution,
strings C:\ProgramData\chocolatey\bin\speedtest.exe | findstr speedtest.exe
showed
speedtest.exe
..\\lib\speedtest\tools\speedtest.exe
Cannot find file at '..\\lib\speedtest\tools\speedtest.exe' (
speedtest.exe
speedtest.exe
And towards the first,
strings C:\ProgramData\chocolatey\bin\speedtest.exe | clip
resulted in this fragment:

A while ago, while writing last weeks post XPath based bookmarklets for Archive.is: more JavaScript fiddling!, I needed the most recent WayBack Machine archival of
https://developer.mozilla.org/en-US/docs/Web/XPath/Introduction_to_using_XPath_in_JavaScript
I vaguely remembered replacing the normal timestamp with a 3 and 13 zeros, so I tried this
https://web.archive.org/web/30000000000000/https://developer.mozilla.org/en-US/docs/Web/XPath/Introduction_to_using_XPath_in_JavaScript
And indeed, it did a HTTP 302 redirect to
https://web.archive.org/web/20220312161117/https://developer.mozilla.org/en-US/docs/Web/XPath/Introduction_to_using_XPath_in_JavaScript
So I quickly made this bookmarklet:
javascript:location.href='https://web.archive.org/web/30000000000000/'+document.location.href;
Then I created another one for getting the screenshot:
javascript:location=location.href.replace(/^https:\/\/web\.archive\.org\/save\/http/,'https://web.archive.org/web/30000000000000/http://web.archive.org/screenshot/http')
That works for screenshots archived with a Wayback Machine account, as these are related because of the inserted http://web.archive.org/screenshot/ fragment:
Since the Wayback Machine always looks for the closest savet timestamp, it does not matter the timestamps in these archived pages have a slight mismatch.
Memory lane
20231006: I edited this section referring two prior blog posts instead of one because of [Wayback/Archive] pbeccard: “@wiert @oliof You can also use…” – Mastodon (clearly showing that Mastodon like any social media platform does mangle backtick quoted code):
@wiert @oliof You can also use `javascript:location.href=’https://web.archive.org/web/*/’+document.location.href;` to get the overview. I find this quite useful since I often want an older version of a page.
And later in the reply chain:
[Wayback/Archive] pbeccard: “@wiert @oliof Ah, I thought b…” – Mastodon
@wiert @oliof Ah, I thought by now that maybe Markdown is supported. I pulled the bookmarklet out of my bookmarklet bookmark folder. Here is a copy: https://gist.github.com/corppneq/d61e3…
[Wayback/Archive] Gist: Bookmarklets
I also found back two blog posts:
- Need to write a proper bookmarklet for the wayback archive (: mentioning many useful Wayback Machine JavaScript Bookmarklets from my gist [Wayback/Archive] Ideas/inspiration for writing a proper WayBack archive.org bookmarklet including this one:
[Wayback/Archive] http://www.gyford.com/misc/wayback.html
I also archived this referred page: [Wayback/Archive] Bookmarklets.com – What’s New.
- JavaScript bookmarklet to replace part of the WayBack machine URL with a bookmarklet replacing
JavaScript bookmarklet to replace part of the WayBack machine URL:
A bookmarklet that goes to the latest rendered saved version (sometimes saved versions have not been rendered yet, so you get the latest available render):
javascript:location=location.href.replace(/^https:\/\/web\.archive\.org\/save\/http/,'https://web.archive.org/web/30000000000000/http')
The WayBack Machine uses a 14-position ID and tries to find the render that is the most close by. This is the format of the ID:
yyyymmddhhmmss
This is granular enough, as the WayBack machine only allows new saves that are usually 30+ minutes apart.
(Note that period by now seems to be increased from 30+ minutes to 45+ minutes)
It also found back this post having the same huge number: 0.30000000000000004.com. How cool is WordPress search (:

I celebrate my tiny milestones by writing blog posts on the things I learn.
What is your way to celebrate them?
Read [Wayback/Archive] Celebrate tiny learning milestones, especially this bit:
It’s really helpful for me to celebrate tiny milestones like this. I celebrate a lot by writing blog posts – I wrote the above list mostly by looking at my list of old blog posts for things I’d written about related to C.
If you don’t blog (it’s definitely not for everyone!), it can be helpful to write down this kind of thing in your [
Wayback/
Archive]
brag document instead.
But I do think it’s important to celebrate these milestones somewhere. It gives me a real sense that I’m making progress and it helps me stay motivated to keep learning about the thing.

[Wayback/Archive] Raspberry Pi And The Story Of SD Card Corruption | Hackaday is long and worth reading.
For me the most important bits are how to prevent SD card wear:
- use good quality power supplies
- put write-heavy operations to SSD
- if it suits your use-case, use OverlayFS
The first is always a good idea. It is the primary reason all our electronics live behind a UPS:
In addition, I posted my personal experience (Samsung microSD cards last way longer than SanDisk cards) on Twitter:
[Wayback/Archive] @hackaday I’m have been running a few Raspberry Pi systems with 8-32Gb micro-SD cards as web-dashboard with refreshes every few minutes or so: much write access. When using Sandisk (no matter the type) they last about a year, Samsung (no matter the type) cards last multiple years.
