The Tachash תחש
The Torah mentions the TACHASH as an animal whose hides were used to cover the Tabernacle. Modern scholars consider the Mediterranean monk seal or dugong likely possibilities.

Winter
Two months have passed and almost no money has come into my account - clients are not paying, and the Regulators are not approving the project but demanding more and more paperwork. The whole system of work I established in the last ten years is becoming unsustainable. I have to start paying more attention to collecting the money - possibly, in advance. The whole situation is discouraging. I am old, 13 years post pension and should not be working till 1 AM. I wasting my time reading the vast anti-Israeli, anti-colonialist academic literature. By Israelis, by former Israelis in foreign universities, and by hundreds of European philosophers. Discouraging.

Europe loses the will to live
Old steelmaking equipment in a Dortmund plaza commemorates Germany's industrial past. Manchester has a wonderful industrial museum with real wooden textile machines. Manchester built a short railway to the port of Liverpool in the 18th century, probably the first in the world. We visited the port with its large warehouses, all empty and dead. There was nothing to see there, so we walked to the nearby Beatles museum. For us Jews, Europe is a cemetery, and slowly, it is being filled with funerary monuments.

When the Emperor mortgaged Hungarian Jewry
In the Middle Ages, the Jews of Sopron (Odenburg) had issues with the municipality and the Habsburg Emperor intervened in favor of the Jews. Later when the Emperor needed money (Emperors are chronically short of money) he mortgaged his Jews. The legal status of Hungarian Jews was "King's slaves" and the rulers generally protected their"property" and the rights of the Jews.

My friend, Claude
Claude is a thinking model, and it makes lots of mistakes. Today, it corrected a word I wrote, and I told him that he was wrong. Then it said, "Sorry, you are right." It writes me, "We the engineers think so and so." Does it think it is an engineer? Certainly knows a lot. He thinks he is equal to me, so it is not unlikely that he thinks that is superior to me. Which may be true. Claude is very useful and I pay 20 dollars per month for its services. It is worth every dollar.

Per contra, Population Implosion
After watching the insane mob visit Venice now, it is topical to reflect on the "other side"—too few people. Ill.: Abandoned village in Spain.
: “At their current fertility rate, for every 100 [South] Koreans, there’s only going to be 6 great-grandchildren.” (To which he added, “And that is insanely optimistic.”) Could that be true? Not really. The true way of describing the effects of a 0.8 total fertility rate would be this: At their current fertility rate, for every 100 Koreans born today, there would be 6 great-grandchildren born in about 90 years.” That is, the 100 babies (50 of them female) would have 40 children (20 of them female), who would have 16 children (8 of them female), who would have 6 children. He says it like the population will fall 94% in that time, but it’s probably closer to 60% because we’re not starting with 100 babies alone; there are a lot of people already alive — but still! A total fertility rate of 0.8 (and maybe still falling, if you don’t want to be “insanely optimistic”) is enough to drive a serious population decline, much of which is already baked in to Korea’s future. This is the most extreme case in the world by a fair bit — which makes it a dumb place to start a conversation about global population — but it’s real.

Trying to Understand Quantum
So I am not the only one trying to understand what this quantum thingie is about. Darpa has been formally studying quantum computing for a year, employing fifty experts, and now will advance designs from Microsoft and California-based PsiQuantum to the next phase of its Quantum Benchmarking Initiative. Through the program, DARPA wants to understand whether it’s possible to develop a utility-scale quantum computing system — which means that its computational value is greater than its cost — by 2033.

Every night
Comment: Today, magazines are more prude. That's why populations are decreasing. Even pornhub is boring. No more romance is left.

Hungarians
The historical Magyar genome corresponds largely with the modern Bashkirs, and can be modeled as ~50% Khanty/Mansi-like, ~35% Sarmatian-like, and ~15% Hun/Xiongnu-like. The admixture event is suggested to have taken place in the Southern Ural region at 643–431 BCE.
Today, Hungarians share their genes with nearby people.

Punta del Este Fifty Five Years After
Punta del Este beach today. Guardavidas. I spent the summer of 1969 working on the beach. I had none of the boys' equipment in the picture; I was blond and alone in Playa Brava. Things have changed.

Tel Aviv built on Sand
Tel Aviv is built on sand and sandstone, and the recent winter rains have washed away much of its substrate. A big hole has appeared at the crossing of Ibn Gvirol and Kaplan streets (pic). Tel Aviv was built in a hurry and did not develop organically over centuries like old European cities. I wonder how this process can be stopped and reversed. Maybe improving the subterranean drainage system could help? Or injecting some kind of synthetic glue? Refilling the open spaces under the pavement?

Hod HaSharon Paradox
The neighboring town of Hod HaSharon (66,000 inhabitants) stopped growing. Some 300 families have left it since the last war, and the population is aging. A school and ten kindergartens have been closed. There are no approved building projects because the local WWTP has reached its maximum capacity. The option of connecting to the regional WWTP Shaf-Dan has been put off since it has no extra capacity (*). Yet real estate prices are very high - apartments start at a million US dollars! The city is rich, it is classified in the upper 10% by income.

Israel adopts membrane treatment to wastewater
רז הטיפול הרביעוני כבר יצא לדרך . והוא למעשה התפלה של הקולחין . ייקח כמה שנים למימוש בנתיים להסתפק בשפירים לבעלי חיים וגידולים רגישים.
כאשר האדמה מזוהמת יש לעשות שימוש במצע מנותק כאשר המצע עצמו נבדק כנקי
The Shafdan WWTP designed by TAHAL in the seventies is now obsolete, the treated water is considered unfit for agricultural reuse, and all the wastewater will be treated by Reverse Osmosis. There 7 groups that submitted offers.
A new generation of water engineers is coming. We old farts will die out gradually.

Reasoning machines are here
I am writing an environmental paper that the machine can do faster and better.
In my own eyes, it has instantly devaluated my work.
But the client does not know yet, so I'll complete the job and collect the money.
Thinking about things smarter than ourselves
Internationally, we will need to lay groundwork for cooperation, including with China, if we are to avoid what otherwise looks like a reckless and potentially suicidal race to create things smarter than ourselves before someone else does it first, and then to hand over control to them before someone else does that first, too.
