@trinsec @WaysideLiege Yep. It's a banning offence actually ("NSFW without a content warning", see qoto.org/about/more#rules for context). I've marked this one as sensitive, but in future please make sure you post with the appropriate content tag.
If you'd like, you can set up your account so that it automatically marks any media sensitive when you post (Preferences > Preferences > Other > Always mark media as sensitive). This might help avoid trouble over NSFW images in future, in case you sometimes forget to tag them.
@realcaseyrollins At least for bitcoin, it's the other way around - the bans reduce demand rather than supply. It's counterintuitive, because we think of mining as producing bitcoin, but mining is effectively "buying" bitcoin with computing resources, and so it's really a form of demand.
The rate of production of bitcoin is fixed (halving events every 210k blocks), so supply is constant - but a miner's expected value for a given contribution of computing resources isn't. With less competition as regulations ban mining in other jurisdictions, a given miner has a greater likelihood of earning the reward and thus a higher expected value for his exchange. That is to say, less demand among miners for newly minted coins depresses the price in computing resources of the average mined bitcoin.
@freemo I think you're right in that it should be a trust network, but not in that it should be an automated system applying rules to determine who's trusted.
I see it working something like your browser's certificate store - you add "editor certificates" to your profile on the qoto-journal webapp in the same way you add "root certificates" to your browser. Each editor forwards submissions to his pool of reviewers and signs the articles they recommend for publication. If an article is accompanied by the signature of an editor you trust, the article shows up in your view of the journal. If an editor includes malicious or incompetent reviewers in his pool, and consequently becomes known for publishing bad papers, people will stop trusting his certificate.
I think an automated system would be prone to people gaming the rules, and the reader wouldn't have the fallback of just revoking an editor's certificate in case things got out of hand. For instance, if I were to try and exploit the rules in your example:
- I might review papers totally outside my competence, because although my experience in fluid dynamics is totally irrelevant to, say, political science, the rules award my review of one equal credit to the other
- I might find another author and set up a tit-for-tat scheme to give each other five free points every iteration, no matter the quality of our papers
What worries me is that if the system initially develops a reputation for being easy to game and accepting of low-quality content, it will be very hard to shed that reputation later on, even if improvements are made. So it needs to be done right the first time.
@freemo I think you need one more layer of indirection. Generally speaking, peer reviewers are supposed to be anonymous, and in any case it sounds unworkable to expect each reader to verify each reviewer's identity and credentials. But if your journal has editors who each verify and evaluate credentials of their own reviewer pool, the reader's decision becomes to trust the judgement of each editor, of whom there are fewer and whose identities are publicly known. Having an editor also means there's someone who can issue retractions, which could be quite important for the journal's credibility if there are bad actors who get something past the reviewers.
Tor doesn't; they just encrypt traffic-in-transit with multiple layers, and each node in the circuit has the keys to pierce only one layer. This means that if your traffic goes through a circuit where an attacker controls both the first and last nodes ("guard" and "exit"), you are subject to deanonymisation.
I don't know about Matrix; I've never used it.
Other services have used the attestation and SGX features built into some Intel processors to (a) protect data in an "enclave" of memory from being spied on - even by hypervisors, and (b) remotely verify that the code with access to the data is unaltered. The downside here is that it limits your distributed platform to running on a pretty small set of hardware.
@freemo My experience is "it's almost always the usb socket the cable plugs into" rather than the cable itself. Especially for pocket-carried devices that can get lint or grit in the socket.
@freemo Depends strongly on what metal & form factor. Here's a guy using it on aluminium sheet. Obviously you're not going to be using it on iron ingots or whatever, though
I've only worked with homebuilt (rather, cobbled-together-in-the-lab-by-grad-students) CNCs, so I can't recommend specific products, but I'll try to pose some questions that you should consider, and maybe in doing so your decision will become clearer.
You say it should be metal-capable. What metals and form factors are you worried about - cutting shapes from sheet steel, milling complex 3D forms from aluminium billet, safely handling something weird like titanium or magnesium?
What size working area do you need? Is that a desktop CNC machine? A freestanding one, maybe the size of an armoire? A full commercial VMC, about the size of a minivan?
Are you comfortable maintaining it yourself, or will you need a professional to keep everything aligned/lubricated/operating? Come to that, do you want to build your own instead of buying a premade one?
Regarding 3D printers, I have a Printrbot Simple, but unfortunately I can't recommend it unless you only want to make orthogonal surfaces - diagonals and curves are terrible. You might consider something modular like the Snapmaker 2.0, which has attachments that can be swapped out to make it a CNC machine, laser cutter, or 3D printer, but of course this will involve compromises that single-purpose designs don't have to worry about.
@valleyforge yeah, it does. The Sleep documentation says it takes an argument of type Duration, which "represents the elapsed time between two instants as an int64 nanosecond count" according to its own documentation a couple entries after Sleep.
They need to get some caber throwers - extremely burly guys who *flip telephone poles* end-over-end. I go to the Highland games most years and can honestly say I've never thought of any of the athletes as effeminate despite every one of them wearing kilts.
@valleyforge So basically filling the role of the interstate logo signs?
@valleyforge Apparently they're more restricted than I thought. A friend of mine got a visit from the cops because his custom sign endorsing a US presidential candidate was large enough to qualify as a billboard, and he didn't have the required licence or permit or whatever.
@mur2501 That's plenty of power then! I actually don't know of any distro that *wouldn't* work on those specs. Maybe not with wobbly windows and other wasteful applications of processing power, but for general use just get whatever you like.
@mur2501 How low on resources are we talking? I run Mint MATE on an old desktop with a Pentium 4. I don't know how well it'd work on a potato, but if it already runs Windows I have a hard time seeing how you'd have trouble.
@valleyforge I thought what my answer would be before listening to that song, and I was surprised how similar they are. So in the hopes you enjoy it too, my saddest song: Kilkelly as recorded by Colcannon
@olamundo [This extension](https://github.com/NicolaeNMV/BehindTheOverlay) creates a Ctrl-Shift-X keystroke to remove overlays from any webpage. It doesn't execute any of the code that is supposed to run when you close the overlay the normal way, which may be a good or bad thing depending on how you look at it. On the one hand, it can protect your privacy not to run scripts or download cookies; on the other, you're likely to get the same popup on all other pages for that site, since it can't store that you've dismissed it.
It is like entropy; the total quantity of crap in the universe increases with time. Theodore Sturgeon determined in 1958 that [ninety percent](https://en.wikipedia.org/wiki/Sturgeon%27s_law) of everything was already crap. You'd think we'd've brought that even higher by now, but it's gone up more slowly than we can measure - apparently we're kind of crap at it.
Happy Riḍván, everybody!
@freemo I'm a little confused by the second chart. Is the knee in the curve, off to the right-hand edge, the breakdown voltage? If so, I think that's kind of showing what I was getting at - up until breakdown it's less than 50nA. That's *nanoamps*! In pretty much any context we'd treat that as an open circuit, no current - but if he thinks that counts as electrons spraying out I guess it's a matter of interpretation.
On the other hand there are some other features of the chart which make me wonder if I'm not getting something. It shows -100nA at 0V and 0A at 50V, roughly, depending on the conditions. I would expect it to pass through the origin instead, and also to be approximately antisymmetric about the y-axis. So it could just be that I don't know what I'm looking at.
