Sharing this for aesthetic reasons only. This is actually what happens when you set a meridian limit. The mount stops tracking at a certain point to keep equipment from colliding with itself. But the effect is like the stars are falling, and I thought it was cool.

Our recent publication "Impact of scaife polishing on electrochemical properties of {110}-oriented single-crystal boron-doped diamond electrodes" is available (should be free of charge via this link before 02 Jan 2026).

It was great to help the colleagues contributing to this work.

A very quick session with M44, the Beehive Cluster, because I woke up early and couldn't stand to waste half an hour of clear darkness.

Two our colleagues, Kristýna and Peter, have recently defended their #PhD theses. 🥳

"Study of #redox and #adsorption behavior of selected #steroid compounds by #voltammetric and capacitive methods". https://dspace.cuni.cz/handle/20.500.11956/205235

Check out the recent paper by Benjamin List, Frank Neese et al. that ones more demonstrates the synergy of experiment and quantum chemistry powered by ORCA (DFT, GOAT, and more)

Do you remember I've told that we have been looking for #PhD students? It was a long and complicated story, but finally we have them all - four(!) new colleagues with excellent background and will to do #science with us. Thank God, no failures in this round.

This department at the #university has probably never been so international. 😎

Our recent #publication " #Homoepitaxial {100} single crystal boron-doped diamond: #nanostructuring and its impact on #electrochemical performance" in Surfaces and Interfaces, https://authors.elsevier.com/c/1k-CM8nATZi-lC (the "Share Link" should be free of charge before June 15).

It was a tough and challenging work. Thanks to all the co-authors for the fruitful collaboration!

Sorry, I cannot stop reading MFA as mean field approximation. Like, they used more than one Slater determinant? Fascinating

Update: it wasn't the ECB blocking gnome-calculator, it was an HTTP library regression breaking the connection to the ECB. Text in [] is incorrect, retained due to RTs etc.

[The ECB have remotely bricked gnome-calculator]

In the latest episode of "Why the 21st Century is impossibly stupid", GNOME calculator contacts the ECB on startup to get currency rates. It just hangs on startup if this fails, the whole calculator not just the currency stuff. [The ECB has blocked GNOME calculator].

To fix this, you can do "dconf write /org/gnome/calculator/refresh-interval 0", whatever tf dconf is, because when I tried it told me dbus-launch is missing, wtf that is, because it doesn't have a package. Turns out it's in "dbus-x11". I dunno why X11, because I use wayland, but I'm past caring at this point. I installed it and it worked.

Now I can calculate how much postage I need to pay for this parcel.

[A bloody OS-shipped desktop calculator, DDoSing a central bank, and blocking on connection failure].

Коротше, хотів спитати щось типу "чи можна підібрати скінченну кількість антибіотиків або як часто треба вводити новий антибіотик, щоб загнати популяцію бактерій нижче певної чисельності без шансів виробити резистентність?", але мені знається на нього неможливо відповісти в загальному випадку. Втім, буду вдячний, якщо можете порадити статті про моделювання динаміки антибіотикорезистентності.

I just installed #LibreWolf, imported all my bookmarks from #Firefox (as an HTML file), and my saved passwords (as a CSV file*). Took me all of 10 minutes, I reckon. And I am now posting this from #LibreWolf. 🥳 #PrivacyMatters #OpenSource

In the end of the previous year the lab managed to send two our #MasterStudents, Kristýna Michnová and Klára Dobiášová, with oral presentations to the student conference " #Chemistry and #technology for life" held in #Bratislava, Slovakia.

I think it is quite important, as a general observation is that the #students coming to us for #diploma #projects lack #practice - in writing and presenting.

Every academic should be able to write code, write a book, engage in critical theory, design an experiment, talk for 5 minutes, talk for an hour, do education research, chair a committee, take orders from a committee, know physics, know history, know linguistics, appreciate literature, talk students down from doing stupid stuff, run a budget, use Word, use LaTeX, use a shared drive, build a website, coordinate a 25-man-deep phalanx, run a book seminar, run a lab. Specialisation is for insects.
