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.
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.
By default, Linux can take up to 15 seconds to write a file to disk, this is for power saving reasons. You could corrupt the last document/photo you saved, your browser profile, or your nextcloud sync.
Linux usually shuts down immediately if you don’t have any unsaved files and nothing glitches out during shut down. But yeah, windows sucks, corrupt files is probably the least of your problems using Windows.
I guess on Linux, if you run sync to write all cached files to disk, and then pull the cord, you’re probably fine.
Journaling should make sure that the file system itself doesn’t corrupt, but journaling doesn’t magically make all writes atomic. If a program is halfway through writing a file and the power is cut, that file will be corrupt.
It is very easy to corrupt files doing this.
Yeah. I honestly think 10GbaseT was a mistake, since it fragmented 10gbit and made it so expensive.
The sfp+ switches aren’t too bad, here’s an 8 port unmanaged for $150: https://www.amazon.com/MokerLink-Support-Bandwidth-Unmanaged-Ethernet/dp/B09W24RZDC/
SFP+ still pretty much requires pcie cards or home-server style hardware to use, but it’s pretty accessible. And you can buy 10GbaseT adapters for backwards compatibility for $40.
Some wifi routers are even starting to adopt SFP+, even if it’s ungodly expensive. https://www.amazon.se/TP-Link-Deco-BE85-2-pack-Tri-Band-router/dp/B0C5Y46J1W/
It’s an algorithm for determining how fast to upload packets. This article just talks about how to enable it.
Here’s the Wikipedia section about it: https://en.wikipedia.org/wiki/TCP_congestion_control#TCP_BBR
The gist is that instead of only throttling upload rate based on packet loss, BBR constantly measures roundtrip delay (ping) to determine how much bandwidth is available.
To be fair, it all trickles down to home users eventually. We’re starting to see 10+gbps fiber in enthusiast home networks and internet connections. Small offices are widely adopting 100gbps fiber. It wasn’t that long ago that we were adopting 1 gigabit ethernet in home networks, and it won’t be long before we see widespread 800+ gigabit fiber.
Streaming video is definitely a big application where more bandwidth will come in handy, I think also transferring large AI models in the 100s of gigabytes may also become a large amount of traffic in the near future.
Like Canada! /s
neural network tools seem really powerful for image filtering and video compression.
Fairphone isn’t super profitable. They just scrape by with not too much growth. The big companies probably simply understand that it’s just cheaper and more profitable to manufacture tons of e-waste and get consumers to buy a new one every year. Hopefully fairphone will be more competitive as new repairability and recycling regulations come into force.
Do you know how many products are US-only?
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.
