DeepSeaTortoise··on German government comes out against Chat Control
For the vast majority of crypto currencies tracing the transactions is trivial. And even currencies like XMR are hardly as anonymous as people think.

The challenging regulations around technically anonymous crypto currencies require you to actively make trackable arrangements with your financial service providers. VERY few people will ever do this, and therefore if anything suspicious were to occur, all you've achieved is putting yourself on the suspect list preemptively.

DeepSeaTortoise··on German government comes out against Chat Control
Sure, if you want to read the messages, but the whole point is that that's rarely necessary and the price isn't worth the minimal gain.

Of the serious criminals, the only ones you'll be catching are those with low technical knowledge (everyone else will just be using their own applications) and the Venn diagram of those with little tech knowledge and those whose digital privacy practices could deceive law enforcement resembles AA cups against a pane of glass.

Regarding Encrochat, it is no surprise that an (unintentional?) watering hole gathered up a bunch of tech-illiterate, the fallacy is that those people wouldn't have been caught if they weren't allowed to flock to a single platform for some time.

Would some people have not been caught until much later or even not at all? Sure, but if LE would do its job (and not ignoring, or even covering up, well known problem areas and organizations for years to decades), only those of low priority.

Is that little gain worth creating a tool to allow Iran or similar countries to check every families' messages if they suspect some family member might be gay?

Hard nope.

> Or just downvoting me.

Don't worry, I rarely do that and that's not just because I can't...

DeepSeaTortoise··on Cuckoo hashing improves SIMD hash tables (and other hash table tradeoffs)
I experimented with Cuckoo tables a lot, but sadly never managed to beat quadratic probing. It's honestly quite depressing just how hard beating "having your data right next to each other" is.

The one thing Cuckoo tables can do much better than anything else I've tried is load factor. Insertions get slow well above 90%, but as long as your buckets are large enough or you got enough inner tables, it'll do fast lookups even at a perfect 100%.

But you'll have a hard time beating getting all the data you'll need for 99% of your lookups within a single cache line.

DeepSeaTortoise··on German government comes out against Chat Control
Why would the malware industry benefit from digital message privacy?

If you're the victim, just hand over the relevant chats yourself. Otherwise, just follow the money. And if the attackers are sitting in a country whose banks you can't get to cooperate, intercepting chat messages from within that country won't do you any good either.

Also, if someone has malicious intent and is part of a criminal network, the people within that network would hardly feel burdened by all digital messages on all popular apps being listened in on by the government. These people will just use their own private applications. Making one is like 30min of work or starting at $50 on fiverr.

DeepSeaTortoise··on ChatControl: EU wants to scan all private messages, even in encrypted apps
With very few exceptions, politicians do know perfectly fine what they are doing.

Each of them has a large budget to hire several staffers presenting every issue to them in ways they understand best, each government has a huge apparatus of various departments with domain experts analyzing every situation from every reasonable perspective and if all of that fails, barely and university or institute would fail to respond to a request for input from an elected official.

Any and all ignorance of any significant politician is by choice. You can't push the oppression a decision causes to the maximum you'll get away with at that point in time without understanding the issue first.

DeepSeaTortoise··on Tell the EU: Don't Break Encryption with "Chat Control"
I always find it very ironic people apply the "don't attribute to malice what can be explained by incompetence" principle to politicians, who are part of the government.

Have you ever had a really great mentor or teacher who was excellent at explaining things to you? Good news, you've now got a budget to hire several of them in full-time exclusively for yourself.

Unsure about something? Just ask and a huge apparatus of several departments, featuring dozens of expert panels with hundreds of domain specific experts each will sift through huge databases, many of them not available to anyone else but the government, of state-of-the-art research, current events, historic events, standards, whatever ..., they will analyze your problem from every possible perspective and make the result of these efforts available to you, together with several recommendations of actions according to the guidelines you provided.

I highly doubt that there are more than a hundred people on this planet who could be incompetent under these conditions. What we're observing is not incompetence, but a conflict of interests, between what they want and how often they need to throw you a little bone to keep you obedient.

DeepSeaTortoise··on Israel committing genocide in Gaza, scholars group says
If you had quoted but one more sentence by accident, you might have included the study that counted individual graves in and around Mariupol:

"According to a 2023 study by Human Rights Watch and two other organizations, there were at least 8,034 excess deaths in Mariupol between March 2022 and February 2023."

DeepSeaTortoise··on Israel committing genocide in Gaza, scholars group says
Compare it to the 2022 Ukraine war. For more than a year almost all the fighting happened in densely populated areas, with many such shorter phases before and since.

And Soviet-stock bombs just aren't as precise and unguided rocket artillery even more so.

Yet after more than 3 years the number of civilian deaths and injured COMBINED just barely surpassed 50k recently.

DeepSeaTortoise··on 15-Fold increase in solar thermoelectric generator performance
Nuclear power plants aren't inherently any more unsafe than the nuclear material itself before having been mined.

What makes them potentially unsafe is nuclear technology having an incredible energy density, which can be misused and the radioactive material being active even without prior activation. The latter makes many radioactive isotopes a very effective poison.

And misuse or bad practices are a general problem. One can build awful buildings, toys or government structures, too.

And if you have a look at what the worst reasonable non-political consequences from a nuclear powerplant meltdown can be, they're surprisingly harmless.

We have to Soviets to thank for their absolutely incompetent response to the Chernobyl meltdown, that we have a good idea of the long term effects. The powerplant never stopped operating, people kept working there every day for decades. Hundreds of people were never evacuated and hundreds more returned within weeks.

Just to put this into perspective: Chernobyl was effectively a dirty super-bomb dispersing 50t of highly active radioactive materials and yet the death count among anyone who didn't approach into rock throwing distance remains 0.

DeepSeaTortoise··on Graphene OS: a security-enhanced Android build
Rethink isn't quite ready yet. Depending on your use case you can go without getting thrown off by a bug for weeks, but when it fails it can be quite annoying. And don't use the GPlay version, but the FDroid or GitHub one.

On the other hand, the functionality is top notch. Easily the best integration of consumer level DNS + firewall blocking in any application on any platform. Just block everything of an application by default and then watch the connection logs for the app and start unblocking stuff via ips, domains or wildcards until the app starts working again.

DeepSeaTortoise··on CARA – High precision robot dog using rope
Hey, I'll reply later to noman-land's comment below, but progress is kinda slow. It takes more time than expected to categorize this many channels and I stopped yesterday after having sorted a bit over 500 and have barely reached the letter "H" (most not tech related ofc, so no worries about getting a monstrous list).

I got a bit more time today, so maybe today evening (German time), elsewise I'll have to skip Friday, so likely Saturday afternoon.

He's easily one of my favorite content creators. Ofc, there are much better engineers, domain experts or more entertaining people on youtube, but he strikes a very enjoyable balance.

I wanted to start writing a list of other tech related, pop-sci and industrial-design Youtubers I kinda enjoy, but noticed just how many channels I'm subscribed to... If there's any interest, I'll drop it, just tell me. Meanwhile I have some filtering and sorting to do.

DeepSeaTortoise··on Ukrainian hackers destroyed the IT infrastructure of Russian drone manufacturer
Most Germans wouldn't be able to recognize Nazism if it was doing the harlem shake on their dining table.

Mention to them that the only way Communism and Nazism differ is Nazism following Engel's nationalist approach to overthrowing capitalism rather than Marx's international one and Nazis having been obsessed with spiritual and Iranian occultism and you're met with blank stares.

Yet those are the fundamentals of Nazism everything else derives from. Including the Holocaust.

Same goes for the understanding of the Nazis "Nationalism". Most Germans just won't believe you when you tell them that it was an absurd use of that term and much more similar to the modern "pro-EU" mindset than the modern understanding of nationalism.

The Germans are propagandized into thinking the definition of Nazis is being called "rightwing" by the media and wanting decentralization of power and cultural homogenity (modern nationalism). Yet the left:

- has already its SA precursors back on the streets (Hammerbande, Antifa, "NGOs")

- is getting rid of free speech to the maximum extent they somehow can pull off within the limits of the law and beyond that through mandatory voluntary industry initiatives (e.g. "Trusted Flaggers")

- are manufacturing external enemies at fault for all wrong (the Russians)

- is spinning up the war machine (massive military spending at 5% of GDP, near limitless commitment to finance the Ukraine war instead of trying to push for peace)

- Are centralizing more and more power in the hands of highly intransparent or even unelected institutions (e.g. EU or international contracts)

And various other stuff. E.g. some of the stuff you can hear on e.g. party congresses of the German "Die Linke".

DeepSeaTortoise··on A Rust shaped hole
I disagree. I like playing around in Rust, but it is near impossible to reason about what instructions will end up being fed to your CPU without having the compiler emit the underlying assembly.

And that makes it very difficult to understand the performance of your code. Just a few days ago I couldn't wrestle the compiler into unrolling a loop (because of a get_unchecked that was hard to reason about), dropping performance of the entire data structure to as little as 30% of a quick proof of concept implementation. The asserts are powerful tools, but only if you can figure out why the compiler is not behaving nicely and how to construct the conditions that will convince it...

DeepSeaTortoise··on Blind to Disruption – The CEOs Who Missed the Future
People dislike the unreliability and not being able to reason about potential failure scenarios.

Then there's the question whether a highly advanced AI is better at hiding unwanted "features" in your products than you are at finding them.

And lastly, you've went to great lengths of completely air gapping the systems holding your customers' IP. Do you really want some Junior dev vibing that data into the Alibaba cloud? How about aging your CFO by 20 years with a quote on an inference cluster?

> Your first list is way too broad and does not capture the particularities that makes fascism different from other kinds of dictatorship.

Fair, but tbh, I'd categorize fascism mostly by the combination of Syndicalism and the nationalist approach to overthrowing capitalism.

> The second list is obviously a ridiculous take

Yes, because this author's points were ridiculous, cut up beyond recognition to fit the author's political agenda. SmolLM-135M would have done a more decent job summing up the original 14 points speech. And even some of the points in the original speech were ridiculous. Like:

"Since even sex is a difficult game to play, the Ur-Fascist hero tends to play with weapons, doing so becomes an ersatz phallic exercise."

DeepSeaTortoise··on Man 'Disappeared' by ICE Was on El Salvador Flight Manifest, Hacked Data Shows
Not really. Umberto Enco's original 14 points were alreay quite questionable, but the author of this hot take altered them beyond recognition.

There is a reason the author linked to a paywall instead of a freely available copy. Just read it yourself: https://theanarchistlibrary.org/library/umberto-eco-ur-fasci...

I skipped over some points, not because they're hard to dismiss per se, but because them being intellectually honest makes them hard to dismiss.

DeepSeaTortoise··on Man 'Disappeared' by ICE Was on El Salvador Flight Manifest, Hacked Data Shows
Correct. It's perfectly normal to be kept in solitary confinement for years before being given a trial.
DeepSeaTortoise··on Germany creates 'super–high-tech ministry' for research, technology, aerospace
You're claiming this, but average German internet speed has but recently surpassed Latvia's, easily beats Paraguay and the Philippines and is closing in on Montenegro and Barbados.

The recent rapid improvements even diminished Romania's lead to less than 250%.

Of course this is only up to the Telekom speedtest server, beyond that nearly all of Germany's 50-100Tbps get funneled through 362Gbps of interconnections onto the open internet.

DeepSeaTortoise··on New antibiotic that kills drug-resistant bacteria found in technician's garden
It only has been a "norm" for a few thousand years during the agricultural era for the poorest of the poor, who could neither obtain hunting privileges, afford to keep their own animals, had no access to food, work or communal programs, which provided them with some meat, or there were significant famines which made the culling of livestock necessary.

Beyond that I'd argue we should strive to minimize class-based access restrictions to food rather than artificaly enforce them.

DeepSeaTortoise··on How each pillar of the First Amendment is under attack
> "Conditional banning isn't banning" which isn't a coherent argument.

It absolutely is a coherent argument and you know that.

"Unconditional availability" inherently excludes "banning" and also "conditional banning" but the latter is a mere subset of "banning". Denying the distinction of the sub- and its superset is extremely intellectually dishonest when that's what the entire argument hinges on.

When I dump hundreds of tons of a book into a river a day and the government requires me to stop doing that, it's not banning the book from the people living downstreams, even despite the availability of the book being reduced for them.

DeepSeaTortoise··on Show HN: LinkedIn sucks, so I built a better one
> All platforms become bad as soon as you allow average Joe speak his mind.

Hard disagree on that one. Average Joe is perfectly fine.

But I strongly agree on professional platforms allowing users to create content being an incredibly bad idea.

A possibility turns into an obligation for success real quick. I have just about 0 interest in creating 10 posts per day to game some algorithm into promoting me. And neither would I like hiring someone who spends 80% of his time awake trying to game some algorithm into enlongating his job title.

DeepSeaTortoise··on Raytracing on Intel's Arc B580
Yup, just went with the $3 per GB formula.

GPU should be about $200 at TSMC (400-450mm2).

+ about $150 for the pcb, cooler and other stuff, I didn't consider

Times a 1.6 to 1.75 factor if they like actually being profitable (operations, rnd, sales, marketing, ...).

So about $1.5k, I guess.

Multiply that with a .33 "screw the competition" factor and my initial guess is almost spot on.

.

Real problem:

The largest GDDR7 package money can buy right now is 3GB. That's a 1376bit bus right there. GL fitting that to a sub 500mm2 die.

In the future you could put that amount of vram on a 512bit bus, tho.

Also normal DDR is getting really fast atm. 8 channel can already challenge most vram configurations. Maybe it's time soon to switch back to swappable memory.

DeepSeaTortoise··on Raytracing on Intel's Arc B580
They should drop a $600 card with 128gb of vram. This is just barely possible without losses on every sale.

And then just watch heads explode.
