This could help debugging issues with Cloudflare hosted sites: /cdn-cgi/ endpoint · Cloudflare Fundamentals docs

Posted by jpluimers on 2026/08/24

If I ever run into a Cloudflare hosted site, I should try fiddling with the site-specific /cdn-cgi/ endpoint that Cloudflare automagically adds: [Wayback/Archive] /cdn-cgi/ endpoint · Cloudflare Fundamentals docs

Via [Wayback/Archive] Dr. Christopher Kunz: “I didn’t know this and it migh…” – chaos.social

I didn’t know this and it might really be handy with debugging weird Cloudflare issues (like pages not loading): Cloudflare adds an URL endpoint to each domain that they host, /cdn-cgi. It has, amongst others, the /cdn-cgi/trace endpoint that shows which data center services your request. More docs here: https://developers.cloudflare.com/fund

The/cdn-cgi/trace endpoint is documented at [Wayback/Archive] Gathering information for troubleshooting sites · Cloudflare Support docs

Dell R730 – Google Search

Posted by jpluimers on 2026/08/24

For my link archive: [Wayback/Archive] dell r730 – Google Search because I first wanted to run a Dell PowerEdge R730 16 Bay SFF, but ended up using the Dell PowerEdge R730xd 24 Bay SFF (plus an additional two 2.5 inch devices in the back) running ESXi on it.

Bookmarklets for going from the Wayback Machine to Archive Today

Posted by jpluimers on 2026/08/20

To ease my blogging, I wrote two more Bookmarklets that help me navigate to or save from a Wayback machine archived page to Archive Today.

A key thing I learned over the past 2+ decades is that “the cloud” (i.e. cloud computing) is “just someone else’s computer” which tends to be unavailable right when you need it no matter the applicable service-level agreement.

Which means that a long while ago, I switched to archiving external links to both the Wayback machine and Archive Today.

Since the Wayback machine is my primary, it helps to have Bookmarklets to go from such an archived page to the equivalent one on Archive Today, or even save it if it isn’t there.

So I made two more Bookmarklets which I will illustrate using the example.org based links https://example.org and http://example.org:

Fixed my Windows Update Error 0x800705b9 on Windows 11 25H2: Reset Windows Update Components batch files

Posted by jpluimers on 2026/08/19

I created the gist [Wayback/Archive] Fixed my Windows Update Error 0x800705b9 on Windows 11 25H2: Reset Windows Update Components batch files from https://kimiyoya.com/windows-update-error-0x800705b9-fix-en/ and https://www.elevenforum.com/t/reset-windows-update-in-windows-11.3808/ · GitHub

In it, the first batch file solved the Windows Update Error 0x800705b9 I had on a Windows 11 25H2 machine, probably with the root cause that the C: drive had become full during running updates.

Standard measures failed:

Some LoRaWAN notes to decide buy or build?

Posted by jpluimers on 2026/08/19

A long time ago, I volunteered to participate in the first Dutch LoRaWAN initiative but somehow no more follow-up after the first initial 2015 email exchange.

Now that I have reached peak recovery of all my cancer treatments and LoRaWAN is far more available there is some room for experimentation.

The pitch deck is dead. Write a pitch.md instead. Oh, and do this for any presentation you need to give.

Posted by jpluimers on 2026/08/18

I have been doing presentations based on Markdown since, gosh let me look, oh, at least 2014¹!

But I’m glad it is getting traction: [Wayback/Archive] The pitch deck is dead. Write a pitch.md instead.

… the “quality” of the deck is inversely correlated with the quality of the thinking behind it …

The quote hits the nail on the head, but be sure to read the rest of the article as well: it’s inspiring, holds for way more than pitch decks: it holds for any presentation, especially because of this quote²:

William Zinsser argued in On Writing Well that the act of writing forces clarity – because you can’t write a clear sentence about a thing you don’t understand.

Markdown has so many advantages. You write. It is text based. It can be versioned. I could go on.

Let me quote the closing summary too, as it is so well written showing the advantages of writing:

Write the pitch.md first. You might find you don’t need the deck at all, or you might find that when you do build the deck, it’s better, because you finally know what you’re trying to say.
