ravingraven··on The real realtime preemption end game
If by "common" user you mean the desktop user, not much. But this is a huge deal for embedded devices like industrial control and communication equipment, as their devs will be able to use the latest mainline kernel if they need real-time scheduling.
ravingraven··on The widespread layoffs are more because of copycat behavior than cost-cutting
>But it's been that way forever in tech companies: SWE make enormous amounts of money and can control their work + environment a lot.

This has certainly not been true since for ever and is only partially now. Only a small minority of developers make enormous amounts of money and there are plenty of shitty companies that do not give you any control whatsoever.

That being said, I do not disagree that part of it is due to the boom-bust cycle of markets, but yeah, managers "coordinate" in a sense that there is a zeitgeist and a common understanding of what the atmosphere is.

They hired people when it was beneficial (note that I am not using the word "profitable" here) for them to do so and now they are firing because that is the new beneficial thing. Keep in mind that managers do not pay you out of their pocket.

A pure market-driven downsizing wave usually touches the C-level too.

For many companies this is counter-intuitive but true. Companies (just like people) are not fully rational economic actors. A lot of the decision-making in companies revolves around power-plays and revenge. Managers fire people they don't like or they feel they do not have leverage over all the time. In a sufficiently large team/company, it is trivial to portray a good performer as a bad one and vice versa. Managers (including CEOs) are just as sexist/racist as anyone and do promote based on biases and personal feelings.

Managment greatly enjoys the feeling of power they have over people and I don't think it is absurd to say that they are fed up with the current dynamic that takes part of this away from them and are firing people just to create an atmosphere of fear.

ravingraven··on Yes, Crypto Is All a Scam
So, you don't care about the movies you watch or the music you hear?
ravingraven··on Yes, Crypto Is All a Scam
No, you can't. Netflix, Youtube etc. (arguably the largest players in the digital properties game right now) have demonstrably failed to do so.
ravingraven··on Yes, Crypto Is All a Scam
Please refer back to my original comment about people hearing NFTs and for some reason which I fail to understand jump to "physical property". NFTs do not work for physical property but they do for digital.

Enforcement of digital rights is actually easier via NFTs than contracts/client apps etc. because NFTs mathematically can prove ownership (courts just have not caught up yet).

ravingraven··on Yes, Crypto Is All a Scam
Digital ownership is enforced by laws and nothing else. There is no amount of code that can technically prevent me from copying any data that lands on my system.

>Tokens signed by an app-trusted key solve the problem with almost zero resource cost.

This ensures safety against access and not against copying. Of course I can not copy assets I don't have access to but the same is true for NFTs.

ravingraven··on Yes, Crypto Is All a Scam
>...but ownership of property requires physical and/or legal protections, which they do not.

This is not true for digital property. Digital property is just as "made up" as the NFT that proves its ownership. People hear "NFT" and for some inexplicable reason jump to physical art.

If the network believes, by whatever consensus methods for proof of ownership that are employed by this network, that you own one coin then those same methods can be used so that the network can believe that you own a certain digital asset. That ownership is just as real as the ownership of a coin.

What people get confused with is the concept of copying or using (both are actually the same problem) this asset. But, this is not an NFT problem, it is a digital problem. All digital assets have this problem, if you give me the asset I can copy and use it without your consent.

Example: I can trivially copy the entire Netflix catalogue on my hard-drive. Since those bits land on my system to be shown on a screen they can just as easily land on my HD as an mp4 file. Are we on any disagreement that Netflix owns those shows? No. But once made available to me, I can use them however I want. Ownership and "use" are to unrelated things when it comes to digital.

ravingraven··on Tether ordered to produce documents showing backing of USDT [pdf]
I was short on Tether for years. Had to give up my position because “Markets can stay irrational longer than you can stay solvent."
ravingraven··on Deutsche Bahn’s Meltdown and High-Speed Rail
>I think the core problem is huge and extremely traditional management.

Not saying that this is not a problem, but bulky management is a constant for DB, even during the years where it was considered world-class. I think it is the budget cuts and the resulting lack of infrastructure.

ravingraven··on Bitcoin value tumbles almost 50% since record November
Nonesense. The Lira has been massively losing value since 2008 while Bitcoin has been massively gaining value for years, the only Turks that are not eating because of Bitcoin are the ones who bought it the past few months.
ravingraven··on Beej's Guide to Network Programming (1994-2020)
Are you guys me? Exact same story. Network programming on embedded systems. Beej to the rescue.
ravingraven··on WhatsApp gives users an ultimatum: Share data with Facebook or stop using app
>Twitter, Facebook and Google need to be treated like utilities [...]

Our generation is reinventing the wheel here, our ancestors had exactly the same problems with the power, water, gas, telephone and rail networks (at some point in time, all those were unregulated and privately owned) and did exactly that. Critical infrastructure needs to be heavily, regulated if not outright publicly owned.

ravingraven··on S&P Dow Jones Indices to launch cryptocurrency indexes in 2021
I live in the EU. I don't have instant money transfers (they are within the day but not instant). Across EU countries it still takes days.
ravingraven··on Tracking Mixed Bitcoins
It is much much smarter compared to any electronic alternative. It is actually the smartest way to do it if done correctly. Only people who do not understand crypto say stuff like that.
ravingraven··on Modern C
Are you refering to this:

https://github.com/BoschSensortec/BMP280_driver/blob/master/...

...?

Because there is nothing inherently modern about this code, this is how C has been written for decades if not from the very start (I think you will struggle to find patterns in this code that are not covered by KnR).

That being said, there are books that cover relatively new developments in the C language and its ecosystem, such as "21st Centry C" by Ben Klemens (but even this book is something like 5-10 years old).

ravingraven··on The Odyssey – Alexander Pope translation (1725)
In Greece it is of course mandatory reading in junior high-school but not in ancient Greek. There are other ancient Greek texts though which are mandatory reading and learning ancient Greek is mandatory as well.
ravingraven··on Automotive Grade Linux
Looks awesome!
ravingraven··on Automotive Grade Linux
I work with embedded systems and I can tell you for a fact that there are exactly two reasons for not including Python or newer versions of it:

1) Hardware constraints. 2) Software must be real-time.

Non-embedded developers are usually unable to understand the constrains of embedded and chalk it up to "you are dinosaurs". Not true.

ravingraven··on Response to Google open letter
Let us not kid ourselves, opting out of Google is suicide for any kind of content. Google is (sadly) critical internet infrastructure by now and lawmakers can not ignore it.
ravingraven··on More than 100 coal-fired plants have been converted to natural gas since 2011
>It's far better to switch to solar/wind/geo/nuclear than natural gas in the long run...

Solar and wind require gas plants as balance when the sun is not shining and the wind is not blowing. All other "infinite" energy sources such as coal or nuclear don't have enough dispatchability to perform solar/wind load following. Hydroelectric has a high dispatchability but is not infinite (the lake level gets too low and you have to wait for the next rain).

ravingraven··on The largest unknown Bitcoin wallet moved nearly $1B for $0.48 in fees
Direktbanken (i.e. purely online Banks) are an exception but they come with their own set of asterisks and are not a blanket solution as you can't open an account from all European countries.
ravingraven··on The largest unknown Bitcoin wallet moved nearly $1B for $0.48 in fees
First of all, you are not allowed to have a German account if you are not a resident of Germany.

Besides that, this is not the point of the conversation. The original comment compared SEPA to Bitcoin, saying that SEPA is better since it is free. It is not. There is no law that mandates it to be free and it is de facto not free everywhere (it might be for your use case but not for everyone). It is many times a lot more expensive than Bitcoin. If I also elect to not transact with Greek bank accounts, I exclude 99.9% of the Greek economy since I have no influence on what kind of account my counterpart has.

ravingraven··on The largest unknown Bitcoin wallet moved nearly $1B for $0.48 in fees
They do not, around 7 Euro will arrive (depending on your bank, but all Greek banks charge a fee). I am a Greek expat in Germany, I do those kinds of transactions very often.
ravingraven··on The largest unknown Bitcoin wallet moved nearly $1B for $0.48 in fees
All banks in Greece charge a fee. The fact that plenty of people do SEPA transfers for free means nothing for the other people (e.g. the whole population of Greece) that can not do SEPA transfers for free.
ravingraven··on The largest unknown Bitcoin wallet moved nearly $1B for $0.48 in fees
Transfer 10 Euro to Greece and let me know how much of it will actually get there.
ravingraven··on The largest unknown Bitcoin wallet moved nearly $1B for $0.48 in fees
A) Not charging differently does not mean it is free (which was the original argument).

B) The "target" bank can still charge you independently of your bank.

E.g. (and I do this kind of transfer very very often so I am 100% sure it is so and I am also 100% sure this is legal): A transfer from Germany to Germany is free. A transfer from Germany to Greece is not as the Greek bank charges a fee.

ravingraven··on The largest unknown Bitcoin wallet moved nearly $1B for $0.48 in fees
They certainly are not. Not between countries (even if they are EU countries and both use the Euro) and not for 1 billion Euros/Dollars.

Edit: A lot of people here are saying "I do not pay for it so it is free". Just because you don't pay does not mean it is free for everyone. The law just states that fees must be the same for domestic and EU transfers, not that the transfer is free and, there are countless examples of regions where there are no banks that charge nothing (especially regions where a lot of intra-EU immigrants come from).

>By analogy you're basically equating tortute in order to prevent the detonation of a bomb to torture in order to detonate a bomb.

I really can not see how I am doing this. Care to illustrate?

>Also, no one included SA as part of the West.

Fair enough.

Neither is Germany. The DDR, sure but there are movies from West Germany there too, e.g. World on a Wire.
