I don't think they can withdraw a model easily, they also supply Pis to industrial markets and they probably have contracts that guarantee supply for a given time period.

I thought anyone serious about mining switched to ASICs and custom hardware a while ago. At least for BTC and maybe eth, a custom asic setup is ~2-3x more profitable

It could be that the instruments were looking at the differential pressure. E.g. the pressure in that section compared to another. A leak elsewhere would throw off the comparison.

I think it's more some security company writing about a vulnerability they discovered in this module or a worm/backdoor and not the company that wrote the software. The security company gets publicity and potentially gets more biz for security consulting.

It is and isn't. I think even if the germans had switched to making mass quantities of Sherman or T42 style tanks, it would have failed because they had shortages things like labor and fuel. The allies essentially had huge industrial bases in the US and Russia that were safe from the threats of bombing and attacks. The entire German supply chain from the factories to field repair sites were constantly being attacked.

The German tanks were superior when functioning but quite a few of them were difficult to produce, maintain, and use. Do better armor and weapons really imply a superior tank if it requires significantly more maintenance and breaks down more often. And that's ignoring the issues were the sheer weight of the tanks meant that they couldn't cross certain bridges or function in certain terrain.

That's better but people typically won't appreciate a thermonuclear explosion overhead in order to take out a missile armed with a few hundred kilos of explosives. That is doubly the case if the nuke is from a neighboring country intercepting a missile targeting them.

Brookhaven does classified research and access to the site is pretty restricted. The last time I visited there were guards with assault rifles at the gates. In comparison, Fermilab used to (and may still) let you walk onto the campus and wander about.

Depends on what you're being attacked by. If it's just regular warheads, a nuclear interceptor is wildly inappropriate especially if the intercept happens over someone else's airspace.

The interesting part is that he got charged with insider trading. A few attorneys on bluesky have pointed out that this is a novel use of this law since previously the trading occurred on regulated markets (e.g. SEC or CFTC regulated markets like stock markets and commodities/futures exchanges).

LPDDR is used by the Nvidia rubin platform. I can see AMD using lpddr as well because it gives you denser memory at the same or reduced power budgets.

Depending on the person, they may have spent years or possibly a decade or more in the US before trying to get an AOS. As such, the USCIS is probably a better adjudicator than a consulate.

I was being pretty generous to the comment I was replying to. Needing 32+ H100s just strengthens my argument that people aren't going to run frontier models locally anytime soon.

We don't know the parameters but it probably takes at least a H100 and possibly several to run a SOTA model. Given the pricing (25+k per H100 + hardware to run it) and power (700W per H100 + hardware to run it), I don't see how anyone except for a largish company can afford to run this.

scheme271 — Mon, 11 May 2026 20:55:13 +0000

ptyxis has a few features that gnome-terminal doesn't and which are really handy. Namely, being able to list containers running on the system and then being able to select one to get a terminal running inside the container. Not sure that warrants replacing gnome-terminal but it is really handy if you use containers a lot.

I think the fees are on order of 1-3% depending on your risk and business type. Certainly an issue but it's mitigated a bit by the decreased costs of going cashless. I.e. cashless operations avoids theft by employees; overhead for stocking, counting, and handling money; reduced insurance due to less chances of robbery; etc.

Uh, who determines that the infrastructure wasn't properly secured? Who is willing to risk prison because some intern accidentally committed an API key or made a dumb mistake. Conversely, what's the chances that no one actually gets prosecuted regardless of how sloppy their security practices are?

Seems fairly logical for any large country to create something like this. Visa/MC is nice but allows the US to apply undue pressure to individuals. E.g. the US applied financial sanctions on ICC officials in the EU resulting in them losing access to Visa/MC credit cards and banks even those are that are purely EU based.

The grassroots institute is an explicitly right-wing/libertarian organization that advocates for their preferred policies. So take their studies with that in mind.

However, the Jones act doesn't really have much of an impact compared to the significantly higher cost of labor in the US compared to brazil and india. Also the US got rid of alot of sugar subsidies, and import controls which essentially made sugar growing aside for some specialized situations infeasible.

The Jones Act doesn't affect shipping prices all that much. If you look at the shipping lanes, the shortest and best shipping routes between Asia and the west coast travels by Alaska. Going to Hawaii adds multiple days and thousands of miles to the route. Also, the harbors in Hawaii aren't equipped to handle the large container ships used for trans-pac shipping routes so the cargo ships couldn't stop in Honolulu even if they wanted to. Finally, the Jones Act allows ships coming from Asia to stop in Hawaii to drop off cargo and then continue on to the west coast to unload the rest of their cargo, this doesn't really happen.
