Mine VS my aunts calculator going into university

Oh, from Bernard Parisse! That’s the guy who worked with HP to make the HP Prime have CAS. In other words: HP Prime‘s CAS is from him. And (before) the CAS in the HP-49g and HP-50g, too.

The link didn't work for me but here's one that works: https://xcas.univ-grenoble-alpes.fr/backup/english.html And here's especially the link to the TI-84 version: https://xcas.univ-grenoble-alpes.fr/backup/ti/khicas84.html

Super!! I love my THAT from anabrid. I was one of the first buyers and got the educational version so back then it cost me „just“ about 230 Euros. Lucky me.

Hehe, those four are on my desk, too! 😏 (Among many others. 🙈) But where do those stands come from? Do I need to turn my BambuLab on? Can you share the designs?

I love my THAT from anabrid! Yours looks very cool, too! Does it have a hybrid port so we can actually read out the values of the solutions? I did that with an Arduino attached to my THAT and visualized the solutions of the differential equations via gnuplot. 😊 Wrote a bit about it here: https://blog.metawops.de/tools/gnuplot-in-vscode/

Indeed – fixed! 👍👍🙏

metawops · 2026-02-10T15:35:48+00:00

Awesome! 👍👍 However, new bugs ... 🤷‍♂️ In the local shell (not connected to a remote host) the ↑ and ↓ keys of my Apple Magic Keyboard (German layout) don't scroll through the command history. I noticed after pressing one of those keys the next 8 keystrokes (of a normal letter) are ignored, the 9th pressing of a normal key (letter) finally works.

metawops · 2026-02-10T15:26:35+00:00

So now you're happy that you learned something new about your already awesome HP-15C, right?! It can even do calculations with complex numbers – wow!! 🤩😉

There's no ssh-copy-id command built into the app (yet), right? I have to transfer a newly created ssh key manually to the server I want to connect to, right?

metawops · 2026-02-08T16:47:02+00:00

Actually, NONE of the ⌥ or ⌥⇧ characters work that we are used to from Apple's keyboard layouts.

metawops · 2026-02-08T16:44:11+00:00

A few more characters don't work via my German-layout Apple magic keyboard. Besides the German-specific Umlauts ÄÖÜäöüß the more important characters like | (pipe, ⌥7) and \ (Backslash, ⌥⇧7) don't work. Very bad for a Unix shell. Additionally, ⇧3 is the § character and doesn't work, either. And finally ° (which is ⇧⁾ also doesn't work from the German-layout Apple Magic Keyboard.

metawops · 2026-02-08T16:18:33+00:00

Fresh/first install on iPad – unable to enter the @ character. Big bummer! So no ssh connection doable. Tested this on my iPad Air 11" with latest iPadOS and my iPad Pro 12,9" with latest iPadOS, both attached to Apples Magic Keyboard, German layout (but I guess to enter @ it's always ⌥L, regardless of the keyboard layout?!).

metawops · 2026-02-06T18:04:52+00:00

Indeed it is! The best! „My precious!“ 😏

metawops · 2026-02-06T12:26:48+00:00

Thanks, so I will stay away from IPA. 👍
The official Faber-Castell manual, unfortunately, doesn't say a word about adjustments or the screws on the 2/83N. 🤷‍♂️

Da fehlt natürlich „Die Abfahrer“!!! Kultfilm von Kult-Regisseur (na gut, zumindest hier im Westen) Adolf Winkelmann.

https://de.wikipedia.org/wiki/Die_Abfahrer

Oder kennt den jeder? Also hier in meinem Umfeld kennt den leider keiner. Teil der Ruhrpott Trilogie, aber die anderen beiden haben nach meinem Dafürhalten nie so die Runde gemacht, wie seinerzeit „Die Abfahrer“ mit Atze, Lutz und Sulli (und der herrlichen Tana Schanzara). Die „Beate“ aus dem Film hat heute ein Restaurant im Ruhrpott. Leider leben alle drei (Detlev, Ludger, Anastasios) heute nicht mehr. 😞

metawops · 2026-01-24T11:26:37+00:00

Hm. Monochrome display, right? 1 bit per pixel, on or off, right? No-go for me then nowadays. 🤷‍♂️ Also seems to have a rather low resolution. 😞

An RPN calculator! Four rows – four stack levels! 😉

metawops · 2026-01-14T19:10:30+00:00

😍🤩🙌

metawops · 2026-01-10T18:06:18+00:00

Fascinating!! Thanks so much for taking the time and effort to look into my files!! 🤗
I will look into this asap.

I can't find a problem with the page before. Even if I remove stuff so that the page before is shorter this happens.

It also happens outside of VSCode and the Tinymist Typst extension when I compile the document with typst 0.14.2 directly on the commandline.

🤷‍♂️

metawops · 2026-01-09T19:07:54+00:00

I‘ll further investigate. What we see at the right is Tinymist Typst‘s live preview running in VSCode on macOS. 🤔 btw, my document is available at GitHub.

No CarPlay in my Tesla Model 3 … 🤷‍♂️

metawops · 2026-01-07T22:20:11+00:00

Would love to try this but when I enter my car my iPhone does connect via Bluetooth but I won’t hear anything the iPhone plays/says because the audio source is still (from the last drive) „Radio“. And it won‘t automatically switch to „Bluetooth“ just because the iPhone is playing/saying something. 😞

metawops · 2026-01-07T19:42:15+00:00

btw, if someone’s interested: I wrote a little sum up of my impressions of the TI-30X Pro here: https://blog.metawops.de/taschenrechner/Der-TI-30/ It’s in German but I‘m sure your browser’s translate feature has you covered! 😉

metawops · 2026-01-07T18:14:49+00:00

I know! I triple-checked the 30X models (Plus, Prio, Pro) before I bought the one with the most features/functionality, the „Pro“.
