Even the newest "64-bit" cpus are really just 48-bit (or 36-bit on low end) or if bleeding edge 56-bit physical adressing processors. This is the maximum amount of virtual memory a process can have access to. You could memory map all your hard disks an still have room to map more physical memory to VMA.
This was an yet another glorious episode from veritasium.
I hope we get well past UVC LEDs. (i.e., shorter wavelengths) UV LEDs are already available. Unfortunately, this progress will stop before X-ray light. With +1 KeV energy, you pretty much must blast off the electrons from the atoms to emit X-rays, which an x-ray tube already does. Or by peeling off a piece of scotch tape.
The backdoor has existed for a month at least. Yikes.
I once helped a person with their computer. They complained the they cant save the their photos. Well, their onedrive was filled to brim with crap, while the local 1Tb disk was empty because they had zero idea how storage and folders work. I had to explain her there is literally 1000x more fast disk space available, so please dont save into onedrive.
Maybe not in a flashlight, but the scientific industry would be very pleased with them. Sterilize water and all surfaces in a second? Flash with 200nm light.
Quantum computing is going to make it possible to solve problems that normal computers simply cannot do.
Most of these are optimizing problems like "compute the best solution to traveling salesman" or "find a molecule that binds to this receptor".
On normal computers solving such problems "perfectly" takes^exponential^ amount of computing time vs. the size of the problem.
Quantum computers are going to chop down that exponential thing a little, so we can see the results before the sun burns out. The reason QCs are theoretically able to do this is that each added qubit improves the machines performance exponentially.
However, the qubit state is so fragile that we need hundreds of them to make a single "stable" logical qubit that can do operations repeatedly. What the quantum computer uses as qubit (photons, super-conducting wire) is irrelevant as long as the system can do useful work.
Because of the fragility, the results are gathered using thousands of runs on the quantum machine and measured statistically.
We are not quite there yet to solve any useful sized problems.
Any new battery technology news needs to be taken with a grain of salt. They are highly likely over-hyped and the actually realized products will have more problems than the current established tech initially.
Based on the article the satellites are not staying 100% on their intended spectrum spec and are bleeding some unintended interfere noise. I hope the starlink cloud doesn't interfere so much that it excludes possibility of some research. On earth, if you transmit even slightly out-of-spec radio signals, the government agencies will get mad and really really fast.
ELI5: Low earth orbit is becoming over crowed "FM radio station", with regulation lacking who can broadcast and at what frequency.
Shorter version: Operating systems set up hardware locks and protections to confine processes, and once set up, they cannot be undone. (the hardware + OS denies modifications to the security policy)
Getting arbitrary code execution and root access is one thing, but breaking out from the damm kernel configured hardware protections is insane.
They basically managed to flip a "read-only" switch to "modify-as-much-as-you-like". The infected device at this point is broken beyond repair, as the firmware(s) may have been tampered with. End result is a terrestrial spy brick.
So, now they are slowly (or immediately and forever, I don't know the time span) injecting propaganda into their clone of wikipedia and they are simultaneously thus admitting they are doing it. (to further brainwash the russian citizens)
So lettme repeat: FUCK PUTIN, and stuff your rubber clones in your ass. (which there are many of)
I read the article enough to find that the Nightshade tool is under EULA... :(
Because it definitely is not FOSS, use it with caution, preferably on a system not connected to internet.
The in-rush of endorphins when the modded LCD thing actually worked probably knocked you out?
A bit of a side story: I disassemble probably 1–5 panels in a week. (For recycling, it takes about 20-45min per panel.) The flat cables alone are so flimsy, I would say just assembling a display again from known, matched and functional parts would take days. I would triple or quadruple that to assemble a display from random parts. Considering this, that modded panel is quite amazing to me.
In standalone panels, the PSU has a chance of killing you: the main capacitors can hold multiple joules worth of nope, charged to about 400v. So, if the main caps are not allowed to discharge (if they discharge at all that is), there is a possibility of death when disassembling a panel with an integrated PSU. Waiting "5min" is bad; a PSU needs to be unplugged for a day or two at least before the charge drains out.
I'm actually bit sad that I had to move onto a ISP which has zero IPv6 support, as I previously did have IPv6. The last thing I did on that connection was to debug the hell out of my IPv6 code I had developed.
He fixed the standard model of particle physics. He was also the reason why this was built to prove his theory.
I wish lemmy communties existed for:
Edit: yeah, I think I miss a few of the old subreddit's. Even if there is an equivalent in lemmy, such communities are quite silent.
The attack is spread via iMessage. A vulnerable device merely needs to receive a bad message with PDF attachment. --> A Remote code execution. No user interaction.
Yikes. Indeed.
The attack entry point is via bad TrueType font + PDF attachment that only needs to processed once. Once a process touches that, the attack vector begins and exploits are chained until they get kernel mode access. After getting kernel mode access all hope is lost, the attacker owns the device.
Only sliver of hope is that fixing the attack entry point blocks the current attack. And that bug is:
This attachment exploits the remote code execution vulnerability CVE-2023-41990 in the undocumented, Apple-only ADJUST TrueType font instruction. This instruction had existed since the early nineties before a patch removed it.
But unless all the CVEs are patched, it is just matter of time a new attack entry point is found.
Windows: $ insmod < "http://shady-ring0-blob-from-internet.sys.cn" What could possibly go wrong?
Finland's blank NATO papers were kept in a safe (30 years figuratively?) and as soon as the war(s) started to cause us harm, they were pulled out of the safe and ratified.
From the news at the time of NATO ratification: "Look in the mirror" - Sauli Niinistö
From the news of the last two weeks: Now the eastern border is pretty much closed for the foreseeable future.
My armchair stance: If the Soviets angered nearly 4 million Finns in the 1940s who had only pitchforks and cows and the result was 126 875 dead and 188 671 wounded Soviets. ^*^ Now there is a nation of +5 600 000 grumpy Finns with access to modern weaponry and a bitter memories of the past...
I don't know what the russian leaders are hallucinating trying to anger us more? :P
Holy fuck I have not seen this fresh wtf garbage in ages. Thanks.
I once said that the current "AI" is just a excel spread sheet with a few billion rows, from what all of the answer gets interpolated from...
I try to filter out most of this negative stuff, but it has a downside. You become disconnected from the raw information feed if you don't occasionally just look at it. For short periods, it's tolerable, but then I just re-enable all filtering to reduce my cognitive load.
If I need to be cheered up, I prefer to look for science articles or news since these are generally about unbiased progress.
Especially now that they’ve started releasing tritiated water into the ocean for the next 20-50 years or whatever the fuck the plan is supposed to be.
the tritiated water is no-more concentrated than what other power plants around the world release. (the latter may be surprising to know) In addition, tritium has a half-life of only 12.3 years and is diluted in a literal sea, which is an extremely good radiation shield.
Thats ~19 cores pegged at 100%, eating 128GiB of ram (OS disk cache included) and bleeding onto swap. 🤯
But it's the spaghetti cabling that makes it work and highly robust.
I would highly recommend Curve25519, etc., just because such keys are faster and less common than RSA public-private keys in today's world. RSA 2048-bit keys are considered weak today, while the Curve25519 256-bit keys remain stronger. Also, the ChaCha20-Poly1305 cipher has an interesting backstory and doesn't necessarily need hardware acceleration (which, in theory, could be borked by the HW-vendor) to obtain good performance.
Unfortunately, some SSH front-ends don't play nice with Curve25519 public-private keys yet... (I'm pointing at the putty SSH client, but that may have improved from the last time I had to use it)
What's happening in the area, I.e. a view of the overall scenery. This vast perspective is different, and it's like looking at a live painting. When I'm on the move, such a observer perspective shrinks to few tens of meters, which kind of makes sense.
I don't think this is anything most people don't do however. I do remember places quite vividly though, and I practically never get lost. People however in the scenery, I forget in about a minute.
NO.
I watched YT channel that had rescue toucans and they belong to the wild. Every 5mins the owner reminds (and I believed he was/is a good owner) of this fact.
Funniest thing was the velociraptor mode and pure chaos. Saddest thing was seeing them die to health complications, despite the good care.
"traveling salesman problem quantum annealing" produces results on arXiv.org, so the math heads are hard at work. :)
Welp, my only calculation was "64 cpu threads * 30% load -> ~19 cores busy", I may be guilty of rounding up too much... The RAM usage is intresting however, since the kernel seems to be caching all it can, to point ejecting uneeded data into swap in order to retain the disk cache. If more ram is reserved by running processes, the (likely pict-rs, database services) disk access times will begin to degrade.
I put too way too much effort in this reply... Yes.. it's nerve racking, especially if you are resorting to BIOS flashback to boot the CPU on an older (new) board.
Can't get visuals (except maybe leds/indicators on the motherboard itself) when your CPU is incapable of accessing the ram or the devices yet. All external devices normally communicate through the RAM. (And by external, I mean not on the CPU package) Yet, the CPU has to solve out this chicken-and-egg problem of how to progress from the cold-boot without knowing what external RAM is installed. There are plethora of timing/clock-cycle/voltage settings for one stick of ram, which are tested on POST. Establishing sane DDR5/4 parameters is non-trivial. (I think it is order of +20!, twenty factorial: 2432902008176640000, if there were no starting point of XMP, JEDEC etc.)
I use hand tuned settings for DDR4, and on cold boot, the BIOS adjust the settings which I didn't forbid it to do. Unless I unplug the PSU from the wall, the BIOS won't retrain the memory again. I suspect my settings still aren't 100% stable. (over period of years) Non-cold-boot assumes the ram works 100% same on each power up. If some OC setting drifts past a threshold once the system is heat soaked or receives more EMI interference, this could provoke a crash/BSOD etc. in absurd theory having a busy wifi router next the ram could cause the bios to select more robust/conservative settings to counter the EMI interference. Would be fun to know, if this would be true.
Our sorrow of the year is the death of Martti Ahtisaari, a Peace Nobelist. May his legacy to be respected in honor, his wisdom would be in great need as of today.
Sauli Niinistö, who will soon peacefully leave us as a president and join the same history books. Sad we can't have a another Kekkonen, depends who you ask. I hope the next president will have a stone cool head in this heated world.:)
What pressuring? They're scared to shit to point of hallucinating threats because they think because we have a prime-eval grudge against them.
If they magically would co-operate with us, drop their shit we would more than happy resume the trade with them.
Gamma rays have so much energy that they are basically emitted only by nuclear processes, as far as I know.
You want benzodiazepines? They are basically erase memory from [0.00 to 24.0] so I definitely wouldn't recommend.
A dum question: if both candidates are unable to function, then what happens? (Trump for his crimes, Biden for getting dementia...)
Meanwhile in Finland: the Finnish version of "build the wall":
The bill needs 5/6 parliamentary approval and politicians are already sweating over it because it touches too many international treaties + constitution. Debate is mostly: is it ready yet? is it ready yet? is it ready yet? (While the committees checking the bill are getting more uneasy by the bill's content...)
Oops, fixed.
