IN VIOLATION OF ITS PRIVACY POLICY AND THEIR RIGHTS TO PRIVACY, TESLA STORED—AND TESLA EMPLOYEES ACCESSED, USED, AND SHARED—VIDEO RECORDINGS AND IMAGES OF CUSTOMERS, WITHOUT THEIR CONSENT

15. Between 2019 and 2022, Tesla employees, for their own personal reasons, and not for any legitimate business reason, viewed and shared sensitive images recorded by Tesla customers’ vehicle cameras. At times, employees would circulate these videos and images, sometimes after embellishing them.

16. One crash video in 2021, for example, showed a Tesla driving at high speed in a residential area hitting a child riding a bike. The child flew in one direction, the bike in another. The video quickly spread around a Tesla office in San Mateo, California, via private one-on-one chats.

georgecmu··on The Mathematical Center of the Universe (2021)
1992 Russia offered Kaliningrad to both Poland and Lithuania, but neither country was interested in a region with seriously underdeveloped economy and inhabited by Russians who wouldn’t feel either Polish or Lithuanian, nor would they speak the language.

Interesting -- I haven't heard about this. Do you know where I can find out more about this offer?

I have spent some time in the summers of 1993-1995 in Lithuania near the border with Kaliningrad on the Curonian spit. I believe the Russian fleet was still based in Klaipeda in 1994.

georgecmu··on Introduction to Algorithms (2020)
Here's a comment I left on a different thread a few months ago, which you may find useful if you're looking for CS contents:

---

There are a lot of book recommendations, but I would not focus on books if I wanted to get the equivalent of a solid CS education. Instead I would work through university lecture slides, assignments, and exams -- basically fast forward through a CS undergrad leveraging what you already know. I'm partial to CMU's CS syllabus for obvious reasons, but I find that it's also one of the most open and available resources on the web; i.e. not locked in on an intranet, etc.

With pre-existing background in software development the basic syllabus is more than doable in a 3-4 months. There are two sequences below: programming and theoretical fundamentals; you can do them in parallel.

Programming:

15-211: Introduction to Data Structures. Used to be in C++; now looks like it's in Java. https://www.cs.cmu.edu/~mjs/121/lectures.html

15-212: Principles of Programming. Still in ML. https://www.cs.cmu.edu/~me/212/schedule.html | https://www.cs.cmu.edu/~fp/courses/96-212/ (unlocked assignment pages)

15-213: Intro to Computer Systems. I hesitate to recommend this; 90% of the value in this course is in the labs and assignments, so it's difficult to do on one's own, but I would at least go through the slides and try to work through exams. https://www.cs.cmu.edu/~213/schedule.html

Theoretical:

15-251: Great Ideas in Theoretical Computer Science. Used to be Discrete Math with a heavy CS lean; it may have evolved. https://www.cs.cmu.edu/~15251/schedule.html

15-451: Algorithms. Here's a decade worth of lectures, exams and assignments - take your pick: https://www.cs.cmu.edu/~15451/ The 2013 course looks pretty complete: https://www.cs.cmu.edu/afs/cs.cmu.edu/academic/class/15451-f...

Next steps:

Since you are interested in VR, etc, you should probably look into the Computer Graphics courses. Note that the undergrad and grad courses are combined; the only difference is the expectations:

15-462: Computer Graphics http://15462.courses.cs.cmu.edu/fall2020/ Exam problems and solutions are gold: http://15462.courses.cs.cmu.edu/fall2020content/exams/finals...

15-463: Computational Photography http://graphics.cs.cmu.edu/courses/15-463/

15-464: Technical Animation http://graphics.cs.cmu.edu/nsp/course/15464-s21/www/syllabus... http://graphics.cs.cmu.edu/nsp/course/15464-s21/www/assignme...

Hope this helps. Good luck!

georgecmu··on US plans campaign to attract Russian scientists, engineers to America & CERN
The US work-based green card application (I-140)[1] has had the 'Soviet Scientist' category for decades. I knew it hasn't been removed after the breakup of the Soviet Union, but I didn't realize it has been in active use this whole time. From a commentary on a USCIS Interim Regulation from 2005[2]:

This benefit for Soviet scientists will be available for a limited time for a limited number of qualified scientists. Therefore, anyone who may qualify under the Soviet Scientist interim rule should begin filing as soon as possible to avoid missing this window of opportunity. This category is supposed to create a win-win situation for the individuals concerned, who are of exceptional ability, and in the national interest of the United States by bringing exceptional scientists to work within the government or the private sector on important projects.

georgecmu··on Can you be sure to clear a line at Tetris?
If you want to test a strategy against an adversarial tetris opponent: https://qntm.org/files/hatetris/hatetris.html

The method by which the AI selects the worst possible piece is extremely simple to describe (test all possible locations of all possible pieces, see which of the pieces' best-case scenarios is the worst, then spawn that worst piece), but quite time-consuming to execute, so please forgive me if your browser chugs a little after locking each piece. If you can figure out a way to accelerate the algorithm without diminishing its hate-filled efficiency, do let me know. The algorithm for "weighing" possibilities is to simply maximise the highest point of the "tower" after the piece is landed.

georgecmu··on More Fakery
I would say that this applies even more so outside of academia. At early stages of development, a research group's or company's product is by necessity a report or a presentation rather than a physical plant's or process's real, quantifiable performance. No malicious intent is required; it's just all too easy to fool yourself or cherry-pick data to support desired conclusions when the recordkeeping is poor.

In my hard-tech experiment-heavy start-up there's no way we could have made any actual technical progress without setting up a solid data preservation and analysis framework first. For every experimental run, all the original sensor data are collected and immediately uploaded along with any photos, videos, and operator comments to a uniquely-tagged confluence page. Results and data from any further data or product analysis are linked to this original page.

As an anecdotal example, we recently caught swapped dataset labels in results from analysis performed on our physical samples by a third-party lab. We were able to do this easily just because we could refer back to every other piece of information regarding these samples, including the conditions in which they were generated months prior to this analysis. As soon all the data were on display at once, the discrepancies were obvious.

The image in the article is low res and blurry. This article makes it clear: https://www.opindia.com/2022/03/nato-shares-image-of-ukraini...

The neonazi and SS symbolism is pretty pervasive in their military, especially in the elite forces and former volunteer battalions. This particular photo got notoriety only because it was published on NATO's official Twitter feed, but there's plenty more on the social media.

georgecmu··on What Happened to Rt.com?
https://www.rt.com/russia/551256-how-access-rt-censorship-by...

Serious attempts have been made in Western nations to silence RT, following Russia’s military offensive in Ukraine. The EU Commission has given regulators in the bloc’s nations powers to ban the media outlet. If you’ve faced difficulties accessing RT’s content due to those restrictions, here are some steps you can take to bypass them.

1. If you’re reading RT on your smartphone, you can use our Android app, which can be downloaded via this link.

2. On your PC, you can use the Tor browser, which can be downloaded here. RT’s website address in Tor remains the same: www.rt.com. If Tor doesn’t work for you, or is unavailable via regular means, you can resolve this issue by sending an empty email to gettor@torproject.com and you will be sent the necessary link.

3. Another way of circumventing restrictions is to use the Psiphon censorship-bypass tool, which can be downloaded for Windows, Android, and other systems. (Windows download here, direct Android download here, and other options here). Alternatively, you can use a VPN service of your choice.

4. You can also stay in touch with RT through Telegram by subscribing to RT’s soon-to-be-reborn channel there.

georgecmu··on Rossiya – Special Flight Squadron Flight RSD88 from St Petersburg to Washington
The usual route from Moscow and St. Petersburg to the Eastern seaboard is over Norway and Greenland, but since the EU airspace is closed to Russian flights, the routes to e.g Cancun, Punta Cana, Porlamar, etc. have to take a detour over Kola Peninsula and the fly over the Atlantic parallel to the North American coast. The detour adds maybe 30 minutes to the flight time.

The reciprocal closure of Russian airspace over Siberia to European and US airlines has a bigger impact on cross-continental flights. The London-Tokyo has been trending in the news, since it's now 3 hours longer and has to go over Alaska, [but I think the bigger impact is on nonstop flights like Washington, DC - New Delhi. These must be completely non-viable now for US carriers.]

edit: Chicago - Delhi was not actually routed over Siberia and is only 1.5 hours longer now: https://www.flightradar24.com/data/flights/ua898

georgecmu··on Russian Cats Slapped with Sanctions
The International Feline Federation (FIFe) has weighed in on the Ukraine crisis, banning Russian-owned cats from competing in its shows as a sanction for Moscow’s military attack on the former Soviet republic.

“The FIFe executive board is shocked and horrified that the army of the Russian Federation invaded the Republic of Ukraine and started a war,” the Paris-based federation said on Tuesday. The group added that it “cannot just witness these atrocities and do nothing.”

As a result, cats belonging to Russian residents will be banned from entry at FIFe shows. In addition, no cats bred in Russia can be imported and registered in a FIFe pedigree book, the group said.

georgecmu··on Antonovs in America (2012)
I think that was because many of the 3rd reich officials transferred seamlessly into the government, intelligence services, and the military of the FRG; effectively there has been no denazification to speak of:

Fifty years ago, the Brown Book: War criminals and Nazis in the Federal Republic—in government, business, administration, the army, the judiciary and science was published on July 2, 1965.

In its first edition, the Brown Book listed the SS ranks and former Nazi membership of 1,800 business leaders, politicians and senior officials of the Federal Republic of Germany. In the third edition in 1968, more than 2,300 individuals were listed—including 15 ministers and state secretaries, 100 generals and admirals of the Bundeswehr, 828 judges, state prosecutors and top judicial officers, 245 leading officials of the foreign office, and 297 senior police officers and employees of the intelligence service. The veracity of the data was supported with detailed statements and quotations from legal, military and Gestapo archives, often accompanied by copies of incriminating documents.

“The whole system is infested with Nazis,” said publisher Albert Norden at an international press conference at the time. The Brown Book sparked a deep political crisis and led to the resignations of numerous officials and government ministers.

It played an important role in the protest movement of the 1960s. Suddenly it became clear that there had never been a “zero hour”—that is, a new beginning for German society after the end of World War II, as announced by the government of Konrad Adenauer. Despite adoption of the Basic Law (German constitution) and the official denazification campaign, key positions in the state apparatus, the government and posts for its representatives abroad were occupied chiefly by former Nazis.

The Brown Book set the ball rolling. After 1965, many more former Nazi perpetrators were unmasked in the German civil service. One thinks of the Baden-Württemberg Minister President Hans Filbinger, who served as a naval judge until the final days of the war, delivering death sentences that were only revealed in 1978

georgecmu··on Flying a single-engine Antonov An-2 over the Atlantic Ocean
Ah, to the plane! Yes, of course -- just like the national identity of Hughes H-4 is Greco-Roman. :)
georgecmu··on Flying a single-engine Antonov An-2 over the Atlantic Ocean
I don't see a lot of value in this line of argument, but want to make several things clear. You impute a single national identity to the plane designers and engineers based on their physical location. Setting aside the fact that the construction bureau itself was relocated to Kiev from Novosibirsk in the late 50s, the people who worked there came from all over in the Soviet Union. Tolmachev and Antonov certainly did not have the national identity you impute.

Regardless, it was a Soviet engineering outfit, not a Russian or Ukrainian one. Just like Chernobyl was a Soviet project and failure, not a Russian or Ukrainian one.

georgecmu··on Flying a single-engine Antonov An-2 over the Atlantic Ocean
It was based at the Antonov airfield, which was captured very early by the Russian special forces and then held for several days under massive assaults from the Ukrainian forces. Whichever side actually destroyed the plane (I would assume it was a Ukrainian artillery barrage), it was almost certainly not done purposefully.

georgecmu··on Flying a single-engine Antonov An-2 over the Atlantic Ocean
It was built in 1988. If anything, it was an incredibly powerful symbol of Soviet engineering and flight expertise.
