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.


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

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

    sudo sh -c 'echo 3 > /proc/sys/vm/drop_caches'
Also fixed your typo in /proc...


Also try:

     sudo sysctl -w vm.drop_caches=3


Or more simply, use

   su -c 'echo 3 > /proc/sys/vm/drop_caches'


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


thanks. copy pasting from the github via my phone, and should have taken the extra few mins


No worries, overall a very useful summary comment.


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.


They swabbed them and sequenced their DNA.


Thank you, I forgot that's cheap enough these days.


That just moves the question to how they figured out the genetic sex determination system of eels, or even how they figured out that sex is genetically determined in eels (and is it? many vertebrates don't have genetically determined sex).


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.


Idk why you are being downvoted, what you said is factually correct.


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

"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.

> 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.


> Were the Taliban destroyed by killing their upper echelons several times over?

Of course not, because that wasn't the goal and would be impossible, because we were recreating the conditions that led to the Taliban taking control in the first place (corrupt and amoral warlords oppressing the populace). Afghanistan's strategic location and suitability for poppy farming and generating dark money flows is why we went in. It was the staging ground for the plans to overthrow "Iraq [...] Syria, Lebanon, Libya, Iran, Somalia and Sudan" (https://www.aljazeera.com/news/2003/9/22/us-plans-to-attack-...). We're still involved in active conflicts in most of those countries.


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.


You're very right, it's important not to forget that hindsight makes the cloudiest things clear. At the time, it seemed as if almost everyone supported the invasion and thought we were taking revenge for 9/11 and liberating the oppressed from a brutal theocracy. It was not until later, sometimes much later, that the facts became apparent. Very few people knew that the Taliban had offered to surrender Bin Laden and hand over Al Qaeda members before the invasion, and almost nobody outside the military knew about what kind of people we were supporting in their stead. Even today when the historical situation is relatively clear I don't think many people have really thought much about the many uncomfortable facts of the opiate/opiod "epidemic" and it's connection to that occupation.


what's the connection to the opioid epidemic?


Fort Bragg has been the transit point for most opiates imported to the US in the past 30 years. Cheap illegal opiates in addition to overprescription of opioids made the problem much worse.


> Afghanistan

Mullah omar died of tuberculosis in 2013. Have to say, pashtunwali meant US found no insiders to assasinate Talibani leadership.


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.


Trita Parsi is an Iranian government lobbyist. Of course he would say that.


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.


So he'd have a better idea of what the govt would want to do?

Keep in mind that a govt that feels (admittedly reasonably) that it has been backstabbed and has its head assassinated would not hesitate to call bluffs instead of acting cool. You've ever seen how a cornered wild animal behaves?


Dulce et decorum est pro patria mori


I wonder how many young minds were twisted by old hypocrites.


the old lie


The young die.


I too played rome total war!


I haven't, but I read the Wilfred Owen poem about young men dying for nothing in WW1.
