boojums··on China Moon Mission: Aiming for 2030 lunar landing
If China has not fought a war in 50 years, how do they have experienced generals? There is no evidence Xi is an incompetent madman.
boojums··on China DRAM Maker CXMT Targets $4.2B IPO as It Takes on Samsung, SK Hynix, Micron
Micron's FQ1 2026 report says they expect their 1-gamma process (uses EUV) to the be the majority of their bit output by the second half of the year. The same report says they've already begun sampling 1-gamma parts to OEMs, so they must have a fab somewhere using EUV already.

boojums··on Ask HN: My mother was scammed out of all her savings. What should I do?
It's more likely his mother borrowed money from other people and he paid her debts.
boojums··on US companies, consumers are paying for tariffs, not foreign firms
Not sure why this comment was dead when it contains an interesting perspective.
boojums··on Musk-Trump dispute includes threats to SpaceX contracts
I vouched for this comment because it sparked an interesting discussion chain on candidate vs. third party spending.
boojums··on Dynamicland 2024
"What if smart boards were actually good, could use the whole room, and track arbitrary physical objects?"

combined with

"What if you could create/edit a computer program like you rearrange furniture in a room?"

appears to be the sales pitch.

I would recommend watching the video though because there are few more pieces to it such as how it is programmed, etc.

boojums··on Americans' love affair with big cars is killing them
If my math is right, the Abrams has a tighter turning radius than a Miata due to how its steering works. The Miata is around 15ft while an Abrams turning would inscribe a circle with a radius of 14ft.

boojums··on Raspberry Pi Pico 2, our new $5 microcontroller board, on sale now
>Support for external QSPI PSRAM

The post claims PSRAM is supported.

boojums··on We need visual programming. No, not like that
Have you used the QP framework (https://www.state-machine.com/)? It supports UML hierarchal state machines with code generation. One embedded dev I know shipped a couple products with it and still likes it.
boojums··on We just broke ground on America's first next-gen nuclear facility
>TerraPower’s investors and development partners, including Bechtel, GE Hitachi, PacifiCorp, and Berkshire Hathaway.

For people not familiar, PacifiCorp is majority owned by Berkshire Hathaway (Warren Buffett). They operate many coal-fired power plants in the region including near Kemmerer where the new TerraPower facility is. I see this as a positive sign for the success of the project.

boojums··on Google's Moonshot Factory Falls Back Down to Earth
A functional government has a monopoly on violence. Funding public sector R&D is tax money well spent, but it's still monopoly money.
boojums··on Micron Samples 256 GB DDR5-8800 MCR DIMMs: Modules for Servers
DRAM/NAND processes are optimized for different things than logic, so there isn't much cross application. My understanding is that it would be hard to make a general compute chip with a DRAM process due to a low number of metal layers, transistor types, etc. Micron [1] and Samsung have both investigated doing massively parallel compute in the memory cell, but the technology never panned out.

Regarding EUV, according to Micron's most recent quarterly report (March 20th) [2]

"We continue to mature our production capability with extreme ultraviolet lithography (EUV), and have achieved equivalent yield and quality on our 1α as well as 1ß nodes between EUV and non-EUV flows. We have begun 1γ (1-gamma) DRAM pilot production using EUV and are on track for volume production in calendar 2025."

boojums··on My Concerns about the TikTok Divestiture Bill as a Software Developer
I vouched for this post because it talks about the Telegram issue and the more general idea of the role of citizen open source intellegence gathering which I think is an interesting and relevant topic.
boojums··on Vision Pro teardown Japan-made parts make up 40% of new device
This was a really well done article.
boojums··on Home schooling's rise from fringe to fastest-growing form of education
I like collecting examples that confirm/deny my biases. Would you mind sharing the demographic differences between the two schools?
boojums··on Report on Anti-Gay Slur Could Put Local News Site Out of Business
https://archive.is/qTw8d The article mentions numerous times that politicians are turning to defamation suits, but isn't it just rich people continuing to use the court process as a punishment?
boojums··on Your Large Vehicle Is Going to Kill Someone in a Crash
On two-lane roads, it is much safer for everyone involved for the pass to occur with high accelleration.

If you don't mind sharing, how does Premium income compare to say Patreon?
boojums··on The D.E.N.N.I.S. system: Résumé tips for Senior Devs
>reasonable baseline

>significantly above average

I don't mean this in a confrontational way, but I am curious how you establish what a reasonable baseline is.

boojums··on An experiment in elastically scaling a thread pool using a PID controller
My understanding is that PID does not work as well for Mulitple Input Multiple Output systems compared with "modern control theory." See the "Analysis techniques - frequency domain and time domain" and "Classical SISO System Design" sections of below Wikipedia article.

boojums··on SVB Securities' CAO served as the CFO for Lehman Brothers' Investment Bank
Would you mind explaining how the comment was "dangerously close" to a dog whistle?
boojums··on Götz von Berlichingen – The “Iron Hand” of the Renaissance (2019)
A translation of his autobiography into English recently came out. https://antelopehillpublishing.com/product/the-autobiography...
boojums··on Food coloring, anti-caking nanoparticles may affect human gut
You could also check out Häagen-Dazs if it is available in your market.
boojums··on So Good They Can't Lay You Off
Do you have any more information on "lightweight effective documentation"? I never seen it work in practice. If there is a method thay has worked for you I would be keen to hear.
boojums··on Buy hi-resolution satellite images of any place on earth
> photo as present

I looked into something similar. If the photo only needs to be somewhat recent I would recommend plane photography. My state does a yearly plane survey, so I used that. If you know anyone in geotech or environmental engineering, they can probably point you in the right direction.

boojums··on The $8 Linux Computer
One proposal I saw was to treat the RV32 core like a microcontroller or as a dedicated co-processor. https://www.robertlipe.com/bl808-not-symmetric/
boojums··on Apple to move 40-45% iPhone production to India
I'm not sure why this comment is dead. I certainly would prefer that West Virginia get some economic activity besides destroying their mountains for coal better left in the ground.
boojums··on The Age of PageRank Is Over
Thanks for posting the interview with Shadi Saleh. I found it interesting they were able to mitigate sanctions by using FOSS software. I wish Saleh had gone into more depth on the hardware side of things which I imagine is also complicated by sanctions.
boojums··on FTX’s financial black hole leaves Binance balking at rescue plan
Interesting to see how heavily Sam Bankman-Fried dontated in the recent midterm elections in the USA. He might run out of runway before those investments pay off.
