Self hosting can save a lot of money compared to Google or aws. Also, self hosting doesn’t make you vulnerable to DDOS, you can be DDOSed even without a home server.
You don’t need VLANs to keep your network secure, but you should make sure than any self hosted service isn’t unnecessarily opens up tot he internet, and make sure that all your services are up to date.
What services are you planning to run? I could help suggest a threat model and security policy.
Not to mention, fiber is cheaper than copper at this point.
Telecoms are just lazy and don’t want to string up new lines.
Ah fair enough, I figured that since the registers are 512 bit, that they’d support 512 bit math.
It does look like you can load/store and do binary operations on 512-bit numbers, at least.
Not much difference between 8x64 and 512 when it comes to integer math, anyways. Add and subtract are completely identical.
Tons of computing is done on x86 these days with 256 bit numbers, and even 512-bit numbers.
There’s plenty of instructions for processing integers and fp numbers from 8 bits to 512 bits with a single instruction and register. There’s been a lot of work in packed math instructions for neural network inference.
And hack their phones so we can see why they want to spy on everyone else’s phones
It was protected by the ECHR in a recent ruling. https://www.eff.org/deeplinks/2024/03/european-court-human-rights-confirms-undermining-encryption-violates-fundamental
However, Chat Control 2.0 argues that since the spying is done before the content is encrypted, it’s somehow ok. 🙄
Yeah, more accurate dead reckoning is always useful, but you’ll still need some sort of of ground-based or satellite based navigation system if you’re using this for any system that requires any reasonable amount of accuracy.
Cheater bots only make up like 1% of the bots in tf2.
The game is dying, the vast majority of players are bots that idle for items.
I’m not sure if they literally use sand as the base material, but SiO2 (aka sand) would have to be reduced to metallic Si before the silicon crystal can be grown.
Time for the EU to regulate including digital goods in estates?
Arrowhead is a very small company. Company details are actually public knowledge in Sweden, and you can see that arrowhead only has 4 board members, two of them being the CEO and vice CEO: https://www.allabolag.se/5567796544/befattningar
Crunchbase seems to think they don’t have any venture capital, so it’s possible that the board members are the only shareholders here, but who knows.
1, These days the machines used to etch chips (flash light onto the chips to carve them out) are mostly made by ASML. The most modern machines are the ASML Twinscan NXE and Twinscan EXE. The raw silicon is coated with different chemicals that react to light, and when the light patterns are flashed onto the silicon, it carves physical arrangements of atoms on the silicon that forms complex electrical circuits.
CPUs were literally drawn by hand, and then the drawing was shrunk down with a magnifying glass back in the day. Programs could be written into electrical memory with physical switches (think 100 light switches), punch cards, or electric typewriters. You could pause the computer so that it would wait for you to type in the next program for it to run. By the time we had kernels, we already had large memory banks in the kilobytes that could store the OS between program runs. So you’d type in the OS once when you turned on the computer, and it would keep in in memory until you turned the computer off again.
The internet is different computers connected together. This website is just data sitting on a server somewhere, and your computer connects to the server over the internet and asks for the data.
Everything is built on the shoulders of giants. There is plenty to learn, but there will always be something you don’t know.
There’s tons of information online if you know where to look. There’s also some good courses out there to understand more specific things like cpu design, networking, programming, etc. In university these sorts of questions fall into the field of Computer Engineering, if you’re looking for a university program to get into.
With regards to the limits of programming: Making websites is already challenging enough, but the cutting edge can be rewarding too :) Software Engineering is a massive field with infinite opportunities. Start small and work your way towards more complex projects with larger teams.
Here’s a good 20 minute video about the history of making microchips: https://youtu.be/Pt9NEnWmyMo
Sure, eyes dont have a “global frame refresh” like computers do. That’s why we can tell the difference between 24hz and 60hz video. Every eye cell is excited independently and continuously.
Still, there’s a physical limit for frame time where 99% of humans wouldn’t notice a full screen flash 99.9% of the time. Being able to shake your head around with a 1000hz vr headset and not perceive and motion blur from sample and hold seems pretty close to that limit.
No shit. These machines are as advanced as a nuclear power plant, they’re gonna have a bit more proprietary software and security protocols than you’d think. Not as simple as just pressing “start” with these machines.
I wonder if asianometry will do a video about the software on ASML machines sometime.
I remember people talking about 1000hz being the holy grail for vr headsets, though so it seems like there’s more consensus on 1000 Hz being a good limit. Frame time is just the inverse of hz.
But yeah ive personally only used 144hz, I think I could see a difference with 204hz, but I’m not sure if I’d be able to discern 480 or 1000hz outside of maybe VR.
1000 Hz seems to be close to the limit human of human vision, since we stop seeing motion blur above 1000hz. Seems like a good endpoint for display technology.
Definitely! If your VPN keeps logs, is in a surveillance-friendly jurisdiction, etc, then details of your internet traffic can be revealed by your VPN. I recommend Mullvad, paid with cash, for the most security. It can also help to pick VPN servers outside of the most egregious jurisdictions, like picking EU servers over US or HK servers.
Coops are still about the money. They’re about saving money by sharing resources with fellow workers/consumers, and maintaining democratic control over the company. You’re not going to get rich from a coop (without embezzlement), but you and your coowners will be cutting out the middle man. Obviously, it only makes sense for industries that you’re heavily invested in.
