New comment by dundarious in "The Doom Justifies the Valuation"

What you have written does not seem to be in close contact with the OP. He talks positively about the GLM news and whatnot. He is highly skeptical only of the "doom" scenarios, including upending most or a massive amount of jobs, and how that is deployed to keep the investment machine working at such breakneck pace.

I don't assume "Mars mission" to necessarily mean cargo for settlement or humans. In fact, that all seems quite distant at this point, so I ignore it entirely unless specific concrete actions occur.

So for many people like myself, the title is perfectly reasonable. The world does not revolve around SpaceX and its purported plans.

It's not special in this regard in the language, or even especially so in the available tooling. Nevertheless, the culture in rust is to add many many dependencies. I occasionally use self-professed "small, modern" CLI tools that use ~400 crates (e.g., interactive podcast downloader).

Relevance is relative, very much so.

How many systems have the relevant NICs, and followed the non-automatic setup steps in https://docs.kernel.org/networking/iou-zcrx.html, and are not running within a VM/container disabling io_uring?

This seems on the low impact end of the numerous historical io_uring issues.

Interesting and important all the same.

No worries, overall a very useful summary comment.

You can't sudo echo and redirect from the non-sudo shell like that.

    echo 3 | sudo tee /proc/sys/vm/drop_caches

    sudo sh -c 'echo 3 > /proc/sys/vm/drop_caches'

Also fixed your typo in /proc...

New comment by dundarious in "Embedded Rust or C Firmware? Lessons from an Industrial Microcontroller Use Case"

Wasn't memory one of the key indicators looked at?

> The analysis and measurements on hardware indicate no strong reason to prefer C over Rust for microcontroller firmware on the basis of memory footprint or execution speed.

I admit I have not carefully read the paper, and am collating info from comments here, so I may be fully mistaken. The word "strong" also allows for much interpretation, that I'm not a priori critical of, but am skeptical of.

The point of noting whether it is loaded on their machine or not, is presumably to indicate that it is not normally loaded (for them), so disabling it to block the exploit should have no impact (for them).

In the satellite tracking experiment, I wonder how they sexed the eels to determine they were female before tagging, given the lack of primary sex organs at that time. Are there obvious secondary characteristics like size?

> The researchers behind this recent discovery used satellite tags to follow 21 female European eels as they navigated the final phase of their incredible journey southwest from the Azores, the volcanic archipelago of the North Atlantic Ocean west of Portugal.

I'm always eager to be corrected if wrong. Such replies welcome.

Previously it was conditional, only in effect “in the event of tension or defense” (machine translation), but they are very exceptional circumstances -- AFAIK not ever invoked since unification.

The change this year was to make it applicable regardless of those conditions: “Outside the tension or defense case, §§ 3 [...]” shall apply.

This is a significant change from the previous Cold War policy. I have talked about the definition of these terms in another comment, with another news article as source.

The change this year was to make it applicable regardless of those conditions: “Outside the tension or defense case, §§ 3 [...]” shall apply.

"Tension" is defined by an imminent threat (e.g., invasion) and must be explicitly invoked by leadership. "Defense" is actual ongoing attack of territory, and must be explicitly invoked by the Bundestag.

The US state is so large, that there are different constituencies operating within it. There was certainly a group that wanted the new state to succeed. I don't disagree with much of what you said though.

Does the fact that he was right enter into your thinking at all by the way? But go on, tell us the basis for your claim, treat us like adults.

> destroying much of Iran's military and leadership

Good at hitting targets, terrible at achieving goals. Same as Afghanistan, Vietnam, etc. Were the Taliban destroyed by killing their upper echelons several times over? In terms of resilience, the Iranians are similar, arguably much more so.

Trita Parsi of RS had been saying weeks in advance that the Iranians would retaliate against gulf states collaborating with/supporting the US & Israel, would close the Strait of Hormuz, and would continue fighting until it established a pain threshold had been reached and acknowledged by its enemies, in order to prevent yet more "short wars". Iran's previous retaliations that were well choreographed and coordinated in advance with US & Israel would not be repeated. He was not alone in saying this, but he was one of the most prominent, connected, and learned people saying so.

Much of the administration and news media are only catching up to all of this long after the fact. Many still cling to the idea that this was unforeseen, or irrational on the part of the Iranians.
