Getting tired of dealing with code generation issues w/C compilers in my project, so I've started working on a fresh implementation of the C code in x86-64 assembly.

I've gotten this to the point where it starts up, switches to protected mode, then to long mode, and can read keyboard input and display some things to the text screen. I'll start rewriting the actual display driver tomorrow, then the ATA driver so I can get it to load the konilo rom & blocks. At that point, I'll hopefully be able to reuse the existing unix ilo-amd64 assembly vm code to run a full Konilo system.

removes Deepin from and later due to numerous violations of packaging policy.
Sounds probably bad for Deepin users, but what surprised me is this:
"In January 2025, during routine reviews, we stumbled upon the deepin-feature-enable package, which was introduced on 2021-04-27 without consulting us or even informing us."
This package basically asked user permission and then injected D-Bus configs and Polkit policies from custom tarballs to circumvent openSUSE strict policy about new D-Bus and Polkit. Sounds shady, right?
But it has been happening for four years! It seems modern OSes and in particular are overbloated.
How can we expect normal user to know their system, if even maintainers have no idea what's happening behind the curtains?
It's good to see this resolved at last, but man, four years!
What's funny, this "shady" package description plainly states that it asks the user if they agree to openSUSE security circumvention to install D-Bus configs and PolKit policies.

Removal of Deepin Desktop from openSUSE due to Packaging Policy Violation

At the beginning of this year we noticed that the Deepin Desktop as it is currently packaged in openSUSE relies on a packaging policy violation to bypass SUSE security team review restrictions. With a long history of code reviews for Deepin components dating back to 2017, this marks a turning point for us that leads to the removal of the Deepin Desktop from openSUSE for the time being.

ALCHEMY MOFOS, WHO'S LAUGHING NOW?

home.cern/news/news/physics/al

ALICE detects the conversion of lead into gold at the LHC

In a paper published in Physical Review Journals, the ALICE collaboration reports measurements that quantify the transmutation of lead into gold in CERN’s Large Hadron Collider (LHC). Transforming the base metal lead into the precious metal gold was a dream of medieval alchemists. This long-standing quest, known as chrysopoeia, may have been motivated by the observation that dull grey, relatively abundant lead is of a similar density to gold, which has long been coveted for its beautiful colour and rarity. It was only much later that it became clear that lead and gold are distinct chemical elements and that chemical methods are powerless to transmute one into the other. With the dawn of nuclear physics in the 20th century, it was discovered that heavy elements could transform into others, either naturally, by radioactive decay, or in the laboratory, under a bombardment of neutrons or protons. Though gold has been artificially produced in this way before, the ALICE collaboration has now measured the transmutation of lead into gold by a new mechanism involving near-miss collisions between lead nuclei at the LHC. Extremely high-energy collisions between lead nuclei at the LHC can create quark–gluon plasma, a hot and dense state of matter that is thought to have filled the universe around a millionth of a second after the Big Bang, giving rise to the matter we now know. However, in the far more frequent interactions where the nuclei just miss each other without “touching”, the intense electromagnetic fields surrounding them can induce photon–photon and photon–nucleus interactions that open further avenues of exploration. The electromagnetic field emanating from a lead nucleus is particularly strong because the nucleus contains 82 protons, each carrying one elementary charge. Moreover, the very high speed at which lead nuclei travel in the LHC (corresponding to 99.999993% of the speed of light) causes the electromagnetic field lines to be squashed into a thin pancake, transverse to the direction of motion, producing a short-lived pulse of photons. Often, this triggers a process called electromagnetic dissociation, whereby a photon interacting with a nucleus can excite oscillations of its internal structure, resulting in the ejection of small numbers of neutrons and protons. To create gold (a nucleus containing 79 protons), three protons must be removed from a lead nucleus in the LHC beams. “It is impressive to see that our detectors can handle head-on collisions producing thousands of particles, while also being sensitive to collisions where only a few particles are produced at a time, enabling the study of electromagnetic ‘nuclear transmutation’ processes,” says Marco Van Leeuwen, ALICE spokesperson. The ALICE team used the detector’s zero degree calorimeters (ZDC) to count the number of photon–nucleus interactions that resulted in the emission of zero, one, two and three protons accompanied by at least one neutron, which are associated with the production of lead, thallium, mercury and gold, respectively. While less frequent than the creation of thallium or mercury, the results show that the LHC currently produces gold at a maximum rate of about 89 000 nuclei per second from lead–lead collisions at the ALICE collision point. Gold nuclei emerge from the collision with very high energy and hit the LHC beam pipe or collimators at various points downstream, where they immediately fragment into single protons, neutrons and other particles. The gold exists for just a tiny fraction of a second. The ALICE analysis shows that, during Run 2 of the LHC (2015–2018), about 86 billion gold nuclei were created at the four major experiments. In terms of mass, this corresponds to just 29 picograms (2.9 ×10-11 g). Since the luminosity in the LHC is continually increasing thanks to regular upgrades to the machines, Run 3 has produced almost double the amount of gold that Run 2 did, but the total still amounts to trillions of times less than would be required to make a piece of jewellery. While the dream of medieval alchemists has technically come true, their hopes of riches have once again been dashed. “Thanks to the unique capabilities of the ALICE ZDCs, the present analysis is the first to systematically detect and analyse the signature of gold production at the LHC experimentally,” says Uliana Dmitrieva of the ALICE collaboration. “The results also test and improve theoretical models of electromagnetic dissociation which, beyond their intrinsic physics interest, are used to understand and predict beam losses that are a major limit on the performance of the LHC and future colliders,” adds John Jowett, also of the ALICE collaboration.

In the electromagnetic dissociation process, a photon interacting with a nucleus can excite oscillations of its internal structure and result in the ejection of small numbers of neutrons (two) and protons (three), leaving the gold (203Au) nucleus behind (Image: CERN)

Hydrologic Outlook, Middle Yukon Valley, 2025-05-09 09:13 AKDT.

ESFAFG

The Yukon River has broken up in Galena. Ice started running Thursday around 5 pm and has continued overnight. Reports indicate that moving ice has continued past Bishop's Rock and down to Nulato. Kokrines Bible Camp reported the river open and ice free on Thursday evening. The ice is quite rotten and moving smoothly with a water level rise of 7 ft accompanying the ice run. River Watch will be flying downriver from Galena to the breakup front today and then checking upstream to see how much ice has cleared out and will provide updates.

Did AI kill your job? If so, I want to hear about it.

The response to my recent story on the AI jobs crisis has been pretty overwhelming. I heard from so many people hit by AI I decided to collect and organize such stories to better understand the phenomenon.

I just pulled the nuclear option on an issue. The issue is one of the many many issues of the form "I made a mistake in my program using your API, and it took me 5 minutes to figure it out. Please change your library to detect my mistake and make it impossible or warn me about it". A request that is often not unreasonable, often unreasonable. I just pulled the "I think this is not really that big a deal" switch on it. Scary switch because now we go down the chute of subjective experience. But earlier in the week, had another one of these and spent the whole day fighting with the guy. Seeing if the nuclear option saves me on cortisol for today.
