The Computer Upgrade Dilemma in June 2023
This is a draft.
Update Alert: Apparently the next generation threadripper pro is months away from announcement and/or release. It would make sense to wait a few months and see what happens.
This is a discussion of the issues one might consider when building/upgrading a home studio that is used for 3D rendering and some machine learning. It has been over 4 years since I upgraded my computing here in Santa Barbara and the world has changed several times in that time period. What I thought would be a straightforward review of existing technologies scaled to my budget has turned into a several month slog through all kinds of things I wish I did not have to think about. I review some of the issues involved below.
There are two different goals.
1. Upgrade my main Linux workstation to improve rendering performance.
2. Buy a completely new, modern technology workstation which would be used for both rendering, localized machine learning, and development.
The 1st goal was motivated by simplicity and cost. I am using a 1st generation scalable Xeon, and bought an entry level CPU for it. There are many more CPUs available, some of them of very modest cost (so it seemed). The second goal could take longer, and fixes a problem I had with limited PCIe bandwidth in the 1st generation of scalable Xeon, especially with the UP configuration or when you did not populate both sockets of a dual socket server. The budget of the latter system would be more expensive, but would solve both problem sets at one time. The budgets might be $1,000 and $5,000 respectively.
But there are many issues, some expected and some unexpected. Issues include:
-- Is there a good difference between what is a server and what is a workstation? The provisional answer is that a workstation has a higher base frequency, has features such as audio on the MB, and has a chipset to handle a bunch of small-change IO such as legacy USB.
-- What are the limitations of the current configuration beyond raw processor power? Am I memory bandwidth limited? Cache limited?
-- What are the real costs of a better 1st or 2nd generation Xeon? Why are there seemingly great deals from unknown vendors but the top vendors keep list prices which are seemingly high for 5 year old technology.
-- Why does Intel make so many different versions of each generation of Xeon. Specialization varies as to the extent of the market? Which ones would I want, or can afford? Not all these processors seem to be equally available from the reputable vendors.
-- What warranty do the "really good price" vendors of refurbished processors offer? My experience with 1st generation Xeon says that you may go through several CPUs before you find one that works, but that once it works it just keeps on working.
-- The AMD threadripper pro is about to be updated. Should I wait a few months for the update? But the updated system will certainly take advantage of newer technology which means among other things a higher memory cost. Do I really care between DDR4 and 5? PCIe 4 vs 5?
-- All of these processors seem to have a "base speed" and a variable "turbo speed" which it automagically uses when it has to. Well it will only do that if several important conditions are met, one of which is that the processor must be cool enough to allow this without exploding or melting. The only way that could possibly work is if we are using liquid cooling for the CPU.
-- My experience in this area a few years ago said that you had to be able to return several non working components before you got one that worked. Choose carefully.
- One issue has been whether or not I save $700 or more and reuse components from the current workstation. Power supply, chassis and disk. Do I really want to destroy a working system, however slow? Hasnt that often been a mistake?
-- As alluded to above, there are real differences between current generation AMD, next generation AMD, 4th generation scalable Xeon and their 5th generation coming out end of year. Whatever you do youre fucked.
What fun. All you need is cash and these issues go away. Thats what the real people do and if you cant just spend you dont deserve anything good.

How Ironic if the Cold Warriors were Right about Russia
All the time I was at RAND and in all the years afterwards, when I read the views of the "cold warriors", I dismissed their arguments that Russia was in some sense evil. Yes, they were an adversary and Stalinism and Marxist/Leninist doctrine caused a lot of (to my mind) needless suffering of their own people and many people who were in some real sense "innocent". But I never really bought the "evil empire" schtick. How ironic, if the Cold Warriors were "right" and Russians turn out to be barbarians who are a threat to civilization. How ironic and disappointing.

"The Menu" (2022)
I liked the idea that cooking should be about love, and what "the chef" loved most of all was to make good cheeseburgers. And in a sense, the movie had a riddle and the riddle was what could penetrate this cold heart. I liked the premise that the world is made of two classes, a privileged elite and the slaves/workers who serve them. I liked the idea that even one of the best rewarded slaves resented being made a whore instead of doing what he did for love. A fallen romantic, you see. I liked that while (most) everyone dies, you die by class: the workers meet one fate, the rich another. And so it was important to know who the young woman was in order to determine which group she belongs in. Ah, a hooker with a heart of gold, then you deserve to die with the workers. I liked the idea that the assistant sous chef attacked our heroine saying (approximately) "I am not going to be replaced! I did not forget the barrel!" I liked the s'mores. I liked the conceit of the cheeseburger as an unpretentious gift of love. I liked the practical fluid dynamics on the fatal neck wound of the betrayed assistant. I like any movie with catfights, and this movie definitely has a catfight. So all in all, not a brilliant movie, but certainly a movie worth seeing.

Notes on Civil Justice and CNN
CNN knew exactly what they were doing when they put Trump on air for their so-called "town hall" with nothing but his supporters in the audience. They knew what he would say and he said them. He verbally abused the woman he had sexually attacked, he all but confessed other crimes, he repeated his lies, he was given an hour of air time in a major national market. CNN is culpable in his obstruction of justice and his attempt to destroy this country and install a fascist government. There are no principles of free speech at stake here. Nothing keeps him from buying an hour of airtime. (Good luck calculating what that would cost).
The supreme court and various appeals courts are a joke having been destroyed by the Republicans. Term limits or some other remedy are required. God knows Thomas won't resign without being forced. The Dems should have raised the debt limit when they had the ability to do so. This situation is essentially their fault as they allowed the Republicans to hold the country hostage. I guess they were trying to be bipartisan. Sorry, sarcasm.
Its too late to put him in jail, I doubt the feds will even try.
I certainly am not a fan of CNN.
