Comment Re:Do not trust "quantum safe" encryption (Score 1) 35

Good points. I'm no expert in the field, but I've taken master's level courses in the relevant math and physics. I particularly remember my math professor saying that no encryption has been mathematically proven safe. We only know the current schemes are safe insofar as nobody has published an attack yet.

We do know how to break certain classical encryption schemes with hypothetical quantum computers. This clearly doesn't mean other schemes will stay quantum-unbreakable forever, because people keep inventing new algorithms. So "quantum safe" only applies in a very limited sense, until the day they are broken.

Comment Commissions position does not matter (Score 4, Informative) 103

As it says on the summary already - the fact that we got a non-answer from commission doesn't matter here. It would have been *nice* to get a legislation from there, but in the end they don't matter.

Ross Scott explains it better at https://youtu.be/CgoODQFrPgw?t... but the point is that SKG already has majority support in European Parliament, and the plan is basically that SKG gets tacked on by the parliament as an amendment to Digital Services Act (https://digital-strategy.ec.europa.eu/en/policies/digital-services-act). The DSA is already supposed to do things like rein in lootboxes, so it's already addressing issues for video games.

Commission's stance ultimately does not matter here at all. No need to be discouraged.

Comment Encryption or signatures? (Score 1) 35

What I have been seeing when talking to bunch of customers who are anxious about the quantum computers breaking ciphers is not so much encryption (as in transmission of data without eavesdropping learning the contents). If your credit card number leaks because you sent it over TLS session that someone captured and cracked with a quantum computer, that's an inconvenience to get a new card, but still minor.

The big interest is in quantum-secure digital *signatures*. No, not the ones on website certificates. But stuff that you use to sign contracts and agreements (hell, even that Iran "deal" was apparently signed using DocuSign). Same for things like deeds, proofs of ownerships, any kinds of contracts that are signed with a cryptographic signature. If someone could fake that yes, they actually did purchase some stock ages ago, here's a completely valid and cryptographic hash, signed by the broker, it would break things. In fact, Bitcoin is supposedly not quantum-secure, so someone could potentially create quite a bit of money by injecting themselves into the blockchain.

So problem is not some transient encryption session cipher, the problem is digital signature that might have lifetime of decades or even longer. If I right now sign a contract to buy a plot of land, and contract uses EdDSA as signature algorithm and someone breaks it in 2040 showing that I have been squatting, and the land belonged to somebody else all along, it will become a problem...

Comment Re:400MW what? (Score 1) 89

Is thet number thermal output or Electric? I'm no expert put afaik it's a rather significant difference

Net electric, it's in the fscking summary:

Overall, the present design of ARC is expected to produce about 1.13 GW of fusion power, with 500 MW of that extracted as electricity. Some of that (100 MW) will be needed to power the plant's operations, leaving 400 MW to be sent to the grid.

I just pay with card. No need to bother with apps anymore.

You know, as it's now mandatory in EU to have all new fast charging stations to have card payment capability and old ones have to be retrofitted. The regular AC EVSE (up to 22 kW) are exempt and do not need a card reader.

Maybe in the future we can have plug'n'charge that is interoperable (CCS standard definitely allows for it), so you'd just enter the credit card info once into your car.

Haven't used an app to pay for fast charging for the past two years. I actively avoid charging stations that do not have card payment option. (And yes, if you absolutely want to use phone, you can always use Google wallet or whatever mobile payment option - but no need to bother with some charging network-specific app).

Comment Distinction between blocking and difficulty (Score 1) 115

I recently bought a small spot-welder in addition to soldering iron. I have already used it to replace NiMH batteries for things like hair trimmer and those solar-powered garden lights. They use the pretty standard AA form factor, so cutting the wires, removing the old battery, soldering the wires to nickel strips and then soldering those to the battery are not too difficult.

Haven't tried to replace lithium battery cells yet, but should also be doable as long as the BMS stays intact and proper care is taken (be careful not to start a lithium fire...). I did replace a battery (that came with BMS included) on an old GPS navigator though (only needed solder), but that's of course a bit different.

Anyway, I've already encountered that even in those cheap lamps you can put in the garden there's clear difference (we have about a dozen of them, obtained at different times). The best one actually had a replaceable AA battery. The others I could replace with the procedure above. And some were just sunken in resin so that if you try to separate the components you are bound to break something.

In my opinion there's a big difference between "dump when battery dies" vs "can be fixed with not-too-costly tools at least if you take them to someone who knows what they are doing". Youtube is full of videos on how to fix your gear. And if you break it while learning then, well, the device was unusable anyway so it's not like you lost anything.

It's the "dump in resin" or similar crap that I hate to actively prevent DIY repairs.

Now, with that said, are you REALLY trying to tell me that nearly half of society is this way? That sounds like an extraordinary claim that will require extraordinary evidence. That's why I wonder if there are not other issues at hand here besides just hunger pains. I know we all tolerate pain differently as well.

This part is completely anecdotal and based only on formed opinion, but I also tried to think back on when the "hungry all the time" started, and my best guess is sometime between 20 and 25. What was I doing then? Well, living on a shoestring budget and studying at university. What do you eat when you live on a shoestring budget and need to study for exams and courses burning midnight oil? Ready-to-eat ultraprocessed crap, fast food, all that jazz.

Not a problem at that time, but my belief without anything really to back it up, is that that particular diet hardwired something in my brain to make my body demand stuff at unhealthily regular intervals stayed even after graduation and better living conditions. After starting a family, diet as in the ingredients in food got even better (you make more effort in cooking when you are no longer just doing it for yourself). However, in your 20s and early 30s, your metabolism can still keep up.

My weight started rising late 30s/early 40s, and ever since then - for the past 10 years, I've tried "everything". Bloodwork and treadmill tests show I'm in excellent health and physical shape apart from that BMI indicator.

Is this something you can generalize to the massive number of people in US (and first world in general really)? Maybe. Don't know. For me, seems plausible but I have nothing concrete to back it up with except the popularity of fast and "ultraprocessed" food in the US. And no, I do not even have a definition for ultraprocessed. This part about original causes for the hunger is all just personal opinion based on following news on the subject.

I made my bed in my early 20s and I'm glad now there's finally some *hope* for fixing it, even if it costs a bunch of money right now. The constant hunger *is* real. It's the same for my two friends I mentioned in GP - I wouldn't have started the medication without discussing with them at length about this - they specifically felt the same way. Now for first time ever I can hope to get rid of it. And no, there are studies that placebo effect (the hope itself) alone doesn't cut it - 20% weight loss with Mounjaro vs 3% with placebo, tops *if* you previously had an inactive lifestyle.

To all of those who say "you just need better impulse control", piss off.

I have two friends who have lost 12 kg with Ozempic and 30 kg with Mounjaro, respectively. Both had starting weights over 110 kg. Both had good diets, exercised regularly. Tests showed good endurance and muscle mass.

I'm myself starting Mounjaro next week, starting at 105 kg.

The problem is *not* diet. It's the fucking hunger. If I eat my stomach full of fries and pizza and cheeseburgers - the epitome of "fat" food, then MAYBE I'll be without hunger for...two hours. Then the hunger comes back. I've stayed - note, *stayed* at the current weight by not eating at all until late evening, because then I can get some sleep with the hunger.

Diet doesn't help. Switching to veggies => fine, I'll eat 4 plates of veggies at a meal instead of the burger. Switching to keto diet => no help.

Getting exercise every day - no effect. Improves resiliency. I can easily bike around the city or jog for kilometers without a break. I can lift weights.

The hunger is *pain*.

We give medication for people suffering from chronic migraines.
We give morphine in palliative care to take the pain away.
We give insulin to diabetics.
We give statins to folks with high cholesterol.

Why the fuck shouldn't we medicate constant feeling of HUNGER?

GLP-1 medications do not "cause" weight loss. They remove the pain of overwhelming hunger. The weight loss happens as an effect to that cause.

There are studies that confirm this - if you are eating because of the feeling of hunger - your body signaling that you NEED food- GLP-1 medications help. If you are eating because of "feelings" - classic stereotypical example chomping chocolate ice cream after a bad breakup as "comfort food" and NOT as reaction to hunger, GLP-1 medication does not help. Because you are not eating because of hunger, so there is nothing to take away.

So all you holier-than-thou fucks who keep repeating "just have some self-control" - stick some thorns in your ass and don't take them out or treat the pain, and you are arriving at the same situation as those of us who just feel hungry ALL the fucking time except 15 minutes since previous meal.
