> How long do government shutdowns last?

That can't be predicted. One side or the other knuckles under at some point, but there is no schedule.

> How often do they happen?

A couple times every decade. Often enough that it one can see trends. The longest is also the most recent: 35 days in 2018. That was Trump's first term. Obama had one as well. They've been trending longer since the 1980's.


Of those approaches mentioned, RTIC is the one I find most interesting. It's worth investigating whether you're dealing with RTOS problems or not. It's not actually an RTOS the conventional sense, but a concurrency framework that repurposes the Cortex-M NVIC as a highly efficient hardware accelerated scheduler, with compile time guaranteed deadlock-free operation in Rust.

How does that happen?

When I see this, I suspect the vendor is operating under conditions that approach absolute chaos: dumping whatever junk someone imagines might be necessary into the stack with zero resistance, for years on end. Zero effort spent on any factoring that might threaten redundancy.


I'm not saying the tools aren't bloated, but I believe that a lot of the size (sorry, can't quantify right now) are the datasets for each and every FPGA model that the tool supports. This includes, among other things, timing information for every wire in the chip. You really only need the files for the device that you are targeting and you do have the option to install only that, or you can install larger groups (e.g. same family, same generation), all the way up to installing every device that ever existed that the tool supports. That's how you get to hundreds of GB.

Are you sure about that, or is it just a guess? If that is the case, how will the open source toolchains avoid the same problem when they eventually become the industry standard? (I can imagine something like a software repository for serving device-specific information on demand.) Are they planning anything right now?

Xilinx toolchain installations used to include a file which was just the concatenation of the license files of every single open source library they were using somewhere inside any of their own software. Now if you installed two or more components of their toolchain (for example, Vivado, Vitis, and PetaLinux) into the shared installation directory, this same file was installed several times as well. Together, they made up something like 1.5 GiB alone.

I think they've fixed this only a year ago or so.


Seems a good candidate for a file that can be kept in a compressed form

Welcome to modern development lol. Try to refactor it and get an answer of "no money for testing".

On top of that, the "agile" mindset all too often also means there is no coherent vision where the project should go, which can and does lead to bad fundamental architecture decisions that need extensive and expensive workarounds later on.

And yes, there have been people describing exactly that in ASML [1], although the situation seems to have improved [2].

> Only tricky thing is if currents induced in motors

Many of the drones in the Russia-Ukraine war are powered by ICEs. I'm thinking of Ukraine's long range drones presently deleting Russia's refinery distillation towers, fixed radar installations, parked aircraft, ammo dumps, etc.

Those engines are not purely mechanical, but purely mechanical engines have been widespread and are still commonplace today. A 2-stroke diesel being one example, but even gas turbines can be purely mechanical. So one can imagine such an adaptation in response to microwave countermeasures.


> Regardless, a 70 kW generator fits on a small trailer. Smaller than the weapon itself. It will run for days on a good sized tank of diesel.

At full load and a thermodynamic efficiency of about ~31% a 70kW generator is about 300hp mechanical. Those fit on a trailer. Not a "small" trailer. A dual axle type trailer with ~1.3 tons of capacity (Cummings C70D2RE.) Military generators tend to be heavier than commercial units. It will burn about ~175 gal/day of diesel, so yes a "good sized" tank about: about ~3.2 55 gal drums every day.

Now, they're imagining "625 element" systems for adequate coverage of a high value site, like an air base. About 2000 bbl/day. That's a little more than 10 large tanker trucks of fuel.

Logistically non-trivial. The Russian's have learned that large fuel trucks are short-lived in drone-dense environments.

Of course, that all for 100% 24/7 operation. I suspect that any real system will quickly become adept at running far less than 100%.


> Are the Europeans insane?

I don't think so. If they were, it would actually be better: one can have sympathy for insanity, and at least isolate it, if not treat it.

Instead, it's extreme insecurity combined with limitless regard for infallible authority. The thought that the hoi polloi might write or say things that are beyond scrutiny is intolerable. That's the insecurity part. And all intolerable things must be criminalized, because in Europe, laws infallibly fix everything. That's the authority part.

That's not insanity. That's just how you behave when you imagine it is your mandate to perfect the world and indulge hubris sufficient to believe you have the wisdom to do so.


Same habit. Can't remember when it started. I've caused myself problems doing this.

Some PDF datasheets somehow prevent selection. Deeply annoying. You just know there is some fool calling that shot, thinking their protecting something precious.


With PDF you can have vector text that isn't detected as text. Some desktop publishing tools layout each glyph individually and the reader may not reconstruct the underlying sentence geometry to base selections on. You can also have scanned bitmap pages with no underlying OCR text layer for the reader to make selections from. PDF text detection and selection is a black art.


I started when using Windows 95.

Selecting stuff allowed me to see if the computer had frozen and required a reboot.

Those where the wild times ;/


So if some rando were to just find one of these huge SIM farms, who could they call, and would anything be done?

With the number of radios seen in the photos from the original story, there must have been a great deal of SMS from that structure. That is very easy to spot with low cost equipment: a TinySA[1] and a directional antenna should be sufficient. Hams do "fox hunting" with similarly basic equipment.

Given the resources of cell operators, the most charitable explanation for how something like this can exist for more than a brief interval is total indifference.

[1] The more recent versions ($150+) are pretty powerful and can see all 4G/5G bands.

And why should they care?

A paying customer is a paying customer, never mind the health and integrity of the public phone network (which coincidentally also serves as the primary identification and authentication method for ~everybody in the US).


These are by and large the same companies who created the caller ID forgery problem to save money when deploying VoIP around the turn of the century. Everyone technical knew that was a bad design but the executives were thinking exactly how you described it, collecting payments for all of that extra traffic until legislation became a risk.


Was there any specific bad design?

As far as I understand it, it's more of the lack of a design (for authentication) that got us into all that trouble, similar to BGP, Email, and many other protocols that were originally designed with trusted counterparties in mind.

It just so happened that the illusion of mutual trust broke down earlier in the Internet than it did in the international phone network. (Some even still believe in it to this day!)


The problem was that they didn’t want the extra hassle of verifying that senders owned the numbers they were announcing. In the earlier SS7 era that was manageable because all of the parties were major phone companies but VoIP opened up a wave of small fly-by-night players. Porting the system forward without recognizing that change in the security assumptions was recognized as a mistake in the early 2000s but the telephone companies saw preventing it as a cost which would also reduce their revenue from delivering all of that spam.

SIM farms are probably against the ToS for most carriers, but otherwise they're not fundamentally problematic just massively inefficient


"It suggests 49 elements, arranged in a table"

The table has 56 elements.

> ChatGPT5Pro to help me generate a periodic table of cognition

This is AI slop.

The core argument of the article doesn't seem to have much value as it's based around some vague link between two unrelated fields of science (the periodic table and philosophy), but perhaps the more interesting part is the impact AI is having on science.


Good to know that LLMs also struggle with off-by-one errors. Maybe zero indexing will buy us another year or so before they take over all our programming jobs.


All those words, and no mention of Section 230, which is what this is really all about. Google can see which way the wind is blowing and they know POTUS will -- for better or worse -- happily sign any anti-"Big Tech censorship" bill that gets to his desk. They hope to preempt this.

Yes, I know about the Charlie Kirk firings etc.
