Is there any research on cryptomoney with central authorities, but also with reduced attack surfaces on a whole system? E.g. authority may be cryptographically bound in some way to only store the database and emit new tokens, but cannot spend them because they get freeze-signed by a receiver to their wallet. Then when you get a payment you check the path of money and algorithmically accept that path only. Anyone who accepts a similar subpath is on their own, because it is double-spending. Subpaths within few minutes self-cancel to prevent instant double-spend.

This is just a vague example, not a working idea. The point of it is that the level of security and trustlessness is not always required to be absolute. E.g. even with fully-secure pow crypto we still have to trust non-crypto claims about usdt, [non?]shitcoins, “hot” wallets, and other maybe-not-ponzis.

Does anyone remembers the good old IRC chat? I think it was a mind-blowing and decentralized option (outside the influence of big tech) to have conversations and debates. Why and when did we bid adieu to IRC and started settling with things like Discord? (which is no doubt good by the looks of it, but still subject to big tech influence)
It won't be public and it won't be distributed - it would quickly revert to some form of centralized piece, hopefully one at each bank, but will probably end up with one huge central point. They will still call it blockchain to attract gen z to work there, but behind the scenes it will work just as badly as the current mess. It's in the bank's/banking industry's blood and regulations to centralize. Whatever gets thrown their way will get locked down and centralized. I can just imagine the huge audit systems that will spring up to audit the blockchain (where ideally you wouldn't need to audit it to begin with, just look at it cause all the same info is in front of all parties, unmodified). Nightmare fuel actually. Better just to start from scratch (new banks, new core banking software, different kinds of audits and regulations).

Have you tried this one? https://lib.rs/crates/csvroll

It calls avx2 intrinsics directly for simd (unfortunately - it's an old library in Rust time, Rust nowadays has great support for portable simd)
This is separate code (a fork of the Little Kernel project) that runs on the VPU and loads later stages of the boot process, including initialising the ARM core and running the Linux kernel on it.

On a personal note, Ben is a really really nice and smart guy. I have a huge amount of respect for him.
this doesn’t justify the contradiction in terms of disliking them for being undemocratic, but losing all respect for them because they refused to use their undemocratic veto

whether proroguing parliament was right or not - it wasn’t - it would absolutely have been worse if they had interfered. one is a temporary political tactic by an elected official to push through legislation - or lack thereof - the other would have completely and unreservedly undermined our democratic institutions as they have worked for over 200 years

I think you slightly misunderstand the role of the royals in this country. they are not consciously acting figures who take an active role in politics. they’re more like the chair that the speaker sits in, or some of the pretty furnishings in the houses of parliament. they’re an aesthetic and we put up with them for that reason and that reason only. you wouldn’t expect the paper that a law is written on to make sure the law itself is democratic and for the same reason you shouldn’t expect the current regent to do the same. they’re a part of the machinery, not a person working it

Check out the hashrate for Ethereum Classic [0], it doubled overnight. Would be interesting to see if it's sustained.

But that is not how /dev/(u)random works and does not give U(255). Generally speaking, it gives some hash of some user/device activity, from these resources:

Since you are using PKI but not a blockchain, it sounds like half a cryptocurrency to me.

I didn't actually say "cryptography" for the block chain. What do you propose other than a block chain for the public ledger? And if your system uses cryptography for the transaction security and has a public ledger, why would you not call it a cryptocurrency? It would seem to be in the same category if you ledger was secure.
Do you have a source for this? I can't find anything about it myself, but you seem to be well-connected with customer support and people who apparently both know and make used of these supposed exploits.
I replied in a few posts in the thread with some details, if you want more there is also this presentation I did at the London performance summit
https://www.youtube.com/watch?v=ZSpxuWQK7sM

Most of the performance exploits for the hashtable (which is the driving engine here) are explained after minute 8.30 (although I would suggest you to watch the entire presentstion).

I will present my work at the p99conf as well.
No, the most ROI efficient cards are 4-5 year old cards (like the RX480). ETH's algo, ethash, is memory hard, which means that it is a false narrative that buying the latest card is necessary. The bottle neck isn't the speed of the card, but the speed of the memory controller.
I was only interested in software rendering, but now i'm curious if hardware rendering can achieve much better results.
I encourage anyone who is interested in free boot/other firmware for the RPi to get involved in the project, it is mostly one person at the moment (not me).
Sure, let's compare the utility of Ethereum to YouTube or Netflix. You must be kidding.

Self mockery, I guess. If you're a fancy restaurant, it implies that you are high end but not arrogant enough to ignore your own mistakes. So, it conveys the message that you are always willing the best for your customers.
Yeah, I did say that Java EE is kubernetes before it was cool :D

Actually, in a way it is sort of sad how unfamiliar we are of the “previous generation’s” solutions. It’s not like load balancing, zero downtime, RPC and scaling are new things.
Don't suppose you have any data to show to back that electricity claim?
Why not do it like Ruby, where blocks always return the result of the last statement (and the return keyword returns from the nearest enclosing function)?
What are these rules? Say for instance 51% of validators decide to include a malicious transaction inside of a block, what rules would that be breaking?
Are you already familiar with better IDEs? Then of course using this is painful.

If you're learning to program for the first time, then i believe using a simpler tool is better, because there is less to learn all at once, and less that is hidden from you. I started programming in EditPad Lite, and that was absolutely what i needed until i started tackling larger projects, at which point it was worth spending the time to learn Eclipse.
Because Creative Commons really needs another non-open license variant like non-commercial that no one really understands what they allow and don't allow so you're better off just not using them if you're being conservative.
And that's exactly what they were saying.
> If it's not in the tech sector then there's not any meaning to that category.

They're not in the business of selling/providing tech and there's nothing technologically novel about what they do. What they do is providing and managing an encyclopedia. Their value proposition isn't some tech, it's their content.

In fact you've got it the wrong way around, because if the bar to being a "tech company" was using or maintaining some sort of technology, then pretty much every company would be a tech company nowadays. In that scenario the category would be truly meaningless.

The easiest way to spot a tech company is looking at their R&D spending: a tech company is constantly exploring instead of just maintaining.
Indeed. If energy is so important and the root of all our problems, we should stop generating and using energy altogether.

I am more and more frustrated with the energy angle of crypto. We live on a technological world that consumes energy, everything has an energy cost. The goal for an advanced civilization is not reduce energy usage, but make it cheaper, cleaner and more abundant! Why does people complaining about "0.5% of world energy usage" think we're researching fusion energy? So we can stop consuming it?

It's such a populist and uninformed argument that drives me up the wall. We can discuss the pros and cons of PoW and PoS, but using the "it consumes as much as X country" argument is intellectually dishonest and pushes forward a particular agenda. How much energy does porn use? Video games? Advertising? Spam? Space heaters? Surely we could do without them and consume even less energy.

Do you know how we can measure the technological advancement of a civilization? By how much energy they have at their disposal ready to use. [1] Not by how much energy they have saved.

We all hate climate change, let's push for cleaner energy instead of glorifying idiotic energy reduction slogans. If governments were to put a tax on energy generation from fossil fuels, crypto miners will be the first to set up hydro and solar plants to run their GPUs. Because mining makes only sense if you can get cheap energy, otherwise it's unprofitable. But that's a more nuanced and intellectual argument than "Bitcoin warms the planet!" and doesn't fit as nicely on a top-voted comment on a forum.

Thanks for sharing. i'm interested to see a comparison and i included the link in one of the comments.
Public health rights and not clogging up hospitals with easily preventable diseases readily outweigh your individual right to not get vaccinated, in general. Had the discussions around the specific Covid vaccines been argued with this in mind, a more productive conversation could be had, but instead it jumps immediately to a conversation about “muh rights” which is wholeheartedly disingenuous and/or selfish.
My only crypto-mining success is that I mined an ether back in the day when it was worth $10. I have it stashed away for a rainy day, but I have no idea if it's going to be worth anything in the future. Can anyone give a TLDR of what this merge means?
Sure, yet most people wouldn't agree to install that camera in their bedroom even so.
Same here! I remember implementing little algorithms to solve these puzzles in Python to get familiarized with the basics of the language.
Bandcamp. The "x items in common" subheading on other profiles has been a very strong indicator of other people with music taste I may also vibe with. As a plus, they seem to be one of the more fair companies with artist distribution payments and their "Bandcamp Fridays", so buying music has a bit more of a feel good factor.
> It does not enforce any syntax style or proper formatting which makes beginners learn that "it doesn't matter" which is wrong imo and leads to horrible looking code.

This is a good point and IMO "format code on save" should be the default in most IDEs and editors - that way if you need a specific set of formatting rules you can configure them, but you won't end up with no formatting (or different people having different ways of writing code) by default.

I think that Go in Visual Studio Code did something like that by default, where you saved your changes and it also formatted everything. Annoying at first, but I came to appreciate the idea.

You can technically achieve the same with something like Git hooks but setting those up is error prone and can be annoying once people get too trigger happy (e.g. someone eventually putting running tests in Docker containers in there before you can commit your changes).

To me code formatting feels about the same as the tabs vs spaces "debate": if you're having it in the first place, you're possibly doing something wrong. Use tab key for indentation, have the IDE insert whatever is configured for the project/org, be it tabs or spaces (e.g. smart tabs), automate it away.

This flavor of argument-by-insinuation is getting really, really old.

Dismissing people or statement because they sound vaguely similar to some foreign source is in itself an obvious propaganda technique that uses exactly the same mentality as the dumbest conspiracy theories out there.
I know how urandom works (consider reading the articles you linked). The number between 0 and 255 is produced by the `od` command:

When will Bitcoin move to proof of stake?
With the estimates that bitcoin is using more than 10x the power of eth. It's time to move.
And proving it in court is hard work, and probably low down the list of attack surfaces your average organized crime syndicate has. Plus criminals are perfectly capable of running moderately-successful businesses and just inflating takings, and genuine restaurant owners are perfectly capable of running places that are only ever full at peak times and with bookings (or are on their way to bankruptcy)
The abuser has as much a right to be there as I do, but I disagree they have a right to act in a clearly harassing/heckling manner. If they have something important to say that's worth protecting with free speech laws, that's not the way to say it.
If that's the sort of behaviour that's protected by the 1st amendment in the US, you're welcome to it.
On the other hand, nor do I ever wish to live in a country that criminalises criticism of anyone, esp. those in positions of power.
Me on the other hand got interested in F#! How does it pay so much considering it's just another .NET (CLR) language at par with C#? Can I benefit by learning F# as a .NET developer?
Bitcoin is using too much energy, and this energy is needed for more important things like heating and transportation.

By 2020, the latest figures we have (page 48 of the Form 990), there were 8 people whose total compensation exceeded $300K. The CEO was at $423k:

This was two years ago. Some of these salaries rose by over 20 or 30 percent in the space of two years, when annual US inflation was at 2%. I fully expect to find even greater salary rises since – once the Form 990 for this year is published sometime in 2024 – as US inflation went up during the pandemic.

Russia and Russian allies control close to 70% of the world's uranium exports (2018) [0]

"Only a handful of facilities in the world convert milled uranium into uranium hexafluoride; Russia produced approximately one-third of the 2020 supply, much of it made with uranium from Kazakhstan. Russia also has 43% of the global enrichment capacity" [1]

"The Biden administration reportedly is considering nuclear sanctions on Russia. U.S. utilities oppose this step for fear that it would make uranium fuel scarcer and more expensive. Many U.S. nuclear plants are already struggling economically." [1]

I live near a major Škoda hub, I have multiple friends working there at different positions - SWEs, support etc (I've myself worked on a Škoda project for few months some years ago - but that was an externally done project so I met only the other consultants). All confirmed the story, but only the support guy encountered it himself directly.

The guy who stole the cars was just a former low-level gang member who got all this stuff prepared for him by others and was only supposed to open the car and drive to Germany. He said it was done by walking to the car with a tablet and pushing a button in an app once it became green. He said he got 1000 EUR for each car. I met him at a bar.

There was a big halo about stolen VW Group cars around here so I believe it fully. It was really unusual how much these cars were being stolen between 2013-2018.
Ah, you link to (your) "actual facts": a few short sentences, and a demand based on one graph. Plus speculation (no details though) that the vaccine is interacting with Omicron. A title with a demand in all caps.

Yay for facts, and not emotions! For the obtuse: the last sentence was sarcastic.

Give me a long detailed scientific paper and then maybe it's worth considering.

I'm not sure what the proper didactic concept is to teach programming. I'd love to see some data, because my personal feelings probably aren't of much use.

BlueJ does have a number of concepts that can be useful in the beginning. The UML view of the classes is a nice way to connect something very abstract with the actual code. Scope highlighting is a great idea too - I tried teaching some people to code and scopes seem to be as difficult a concept as classes are. Having the IDE change based on some text you wrote is pretty good too - like seeing relationships form in the UML view, listing public members on classes and so on.

The only problem I see is helping people move on from BlueJ. Some people who struggled a lot learning the basic concepts may feel like they finally managed to find a setup that "works" for them that's mostly based on a task-based understanding:

"I click on the BlueJ icon on my desktop, I click here to create a new class, if something doesn't work I better delete everything and start again because I don't know where to go from there"

Other IDEs aren't necessarily better! What does it actually do under the hood? How do I create a program that I can run outside of the IDE, not to mention on another person's computer?

Maybe that's not the problem of an IDE, rather it's the teacher who needs to include that transition in their course. I remember how back in school/university that was hardly mentioned at all.
Even more so because realistically you need to set it up somewhere where electricity is cheap which which is a centralizing force in itself. Also you need to have a really efficient mining rig for it to be profitable. With Ethereum PoS you can easily home stake on a Raspberry Pi which means it is much easier for regular people to participate.

It’s generally claimed that reading other people’s code is harder than writing your own. I mean, everybody loves writing code on a greenfield project but hates maintenance of legacy code, right? So, why do people like these code generators? The only explanation I can see is that people use them and then don’t read the code. Which would be horrifying.
