So what if several functions that use less than 4KB each call each other before using the stack variables in a way that the first access skips over one page?

I don't know if an optimization is allowed to "invent" a write, but I would be surprised if an optimizer goes that far because I have to believe that the number of cases where more writes improve performance are pretty slim.

New comment by stkdump in "We finally learned to center a div, then browsers added sidebars"

stkdump — Wed, 05 Aug 2026 05:10:41 +0000

Funnily I can't reproduce the effect at all. I am using Firefox and with sidebar the content of the page centers on the remaining viewport width, like any other site does. I have also tested with Edge, same result. With Edge's auto collapse (i.e. non sticky vertical tabs), I get the described effect, but again this is like any other site. I was actually expecting quite bad results in Edge because it has some sidebars on the right and I thought this page compensates in the wrong direction then. Don't have Chrome installed to see if that does anything differently.

Note I like the default behavior of browsers to center on the viewport as opposed to the window treating sidebars as overlays over the page. Whenever pages do that with their own gadgets I hate it, because they often don't move their content out of the way and it makes it unreadable unless scrolled out of the range of these gadgets, which often isn't possible at all. And even when it is, it effectively reduces the total usable screen to a fraction.

Whenever I'm bothered enough (happens mostly on mobile), I use a kill sticky bookmarklet to fix that.

817 kWh here. Though june last year was the record at 904 kWh. Maybe the effect is that solar panels lose efficiency when too hot.

No, I don't know if they do and honestly this isn't why I wrote what I wrote. But what if I don't want to buy anything from them? I want to de-google and my only choice seems to be to have a device with a google logo on it that puts even more money in their pocket than if I just use normal Android with minimal google interaction on a Samsung or OnePlus device.

The whole GrapheneOS thing is a bit of a joke. So you either have to buy google hardware or you run google software.

Anyway, looking forward to the widespread introduction of Wero. Maybe there will be some options for third party roms in the name of digital soveranity. Seems like they want to make the EUDI wallet for digital documents no-google capable for that reason at least.

One of the rare cases where a vpn actually does help. Though of course only if they don't also turn over records.

New comment by stkdump in "Our position on open-weights models"

China will likely gain the capability to produce leading edge chips within a decade domestically. From then, occupying Taiwan will be about controlling the wests the access to that. Same with AI models, though I would say we are already about there. Dario is either lying to us or to himself that distillation plays a major role.

I think you were able to buy VS Pro perpetual licenses for one time 500-1000 at all times. Of course they had higher tiers and a subscription model which were more expensive but in reality for most people there was little to no added value.

I strongly suspect that the horizontal and the vertical strength are not perpendicular. I suspect having a very wide knowledge gives you access to patterns that reproduce across fields that an expert would lack.

I think the point is that:

1. Yes Windows must have "approved" the drivers

2. Windows Update runs automatically and not (usually) manually

3. Automatic update can't even be disabled, only manually postponed a bit

At least 2 and 3 are different on virtually every Linux distro. Also, I find it very unlikely that they would accept such behavior.

To give MS the benefit of the doubt here, now that this happened and has been reported on they might decide to enforce stricter rules on manufacturers in the future. But as a Windows user you don't have a choice in case you don't like how they decide and how their decisions might change again later.

stkdump — Sat, 27 Jun 2026 05:36:47 +0000

Possible. Though I think open source innovation of hobbyists is currently hampered, because of open weights releases by chinese labs. I believe once the labs stop doing this, a globally coordinated open source ecosystem will fill the gap.

I think they mean cheat in a Dieselgate sense. You detect that you are being tested with a specific benchmark question and heuristically give the correct (manually programmed) answer. That wouldn't be AGI.

No, I have the same experience. Feels crazy that a GPU is too expensive and then the advice is to spend 400$+tokens on openrouter each month.

stkdump — Sat, 13 Jun 2026 19:44:15 +0000

Sorry to be that guy. I think the more precise wording would be that you get tokens which would cost $1,000/month at API pricing. Maybe (depending on the profit margin of the API pricing) you incur costs somewhere close to $1,000/month. And maybe your usage is subsidized by 900$/month. The value you get out of it is a whole other question. One that according to recent news, CFOs find hard to esitimate.

New comment by stkdump in "Tracing a powerful GNSS interference source over Europe"

stkdump — Fri, 05 Jun 2026 18:59:10 +0000

One can tell that this is 'from far away'. Europe was hoping that Russia, in their own interest would pursue peaceful cooperation, even when Putin was already talking about 'spheres of influence'. When Russia invaded Georgia, Europe turned the blind eye and was still hoping for peaceful relations with Russia. When Russia annexed Crimea, same thing. Even when Russia was pulling together forces along Ukraines border and the US pulled out their personnel from Ukraine, there were still many voices in Europe that Russia would never invade Ukraine. We can all be lucky that Ukraine wasn't as naive and prepared for this moment, otherwise Russia would probably have invaded a couple more countries by now.
