A tunnel. I've used these before https://tunnelbroker.net/ and https://www.sixxs.net/main/ probably 10 years ago now. They were pretty good. But of course you need something to act as a router on your network for it to set it up for the whole network. A raspberry pi would be enough or anything running linux. Of course you can probably just set it up on one machine too. I've never done that though.

Other providers will start charging more, the US and Europe have ALL ipv4 allocated now. So, yes the cost of a scarce resource goes... Up

Most of the big websites are on ipv6. Twitter isn't (but is that anyone's loss?). I think the only way we can all make sure the stragglers move to ipv6 is if we all leave an ISP that doesn't offer it.

After all these years it really should be the dominant stack.

r00ty Admin ,
r00ty avatar

Yeah, my company totally blocks ipv6 when the VPN is on. Not sure why they're so backward for a tech company.

r00ty Admin ,
r00ty avatar

I suspect greed is involved. But since the new allocation of ipv4 hasn't been possible for quite some time in US and Europe. I think the price of those IPs that are assigned to providers is going to gradually rise.

And to think, I remember when I got a business ISDN account for my old office. They pretty much just gave you a free (well included in the price) /24 without even asking.

Different times.

I think it's more like the previous commentor said. It's the communities more than the users. Every post, comment, like needs to be sent to every other instance that subscribes to the community. I suspect it's definitely connected to federation. The reason being, at 20:00 utc yesterday lemmy.world stopped sending my instance anything (previously it was between 2 and 5 messages a second). It only started again at around 00:00 utc. I wonder if they were slowly adding instances back to federation?

In any case the load for that many communities with that many other instances must be huge. The advantages of the fediverse requires that communities AND users are spread between instances. In the current climate, the super instances have most of both and it must be becoming exponentially harder to keep up with hardware requirements for this.

r00ty Admin ,
r00ty avatar

I don't know that it's a DB design flaw if we're talking about federation messages to other instances inboxes (which created rows of that magnitude for updates does sound like federation messages outbound to me). Those need to be added somewhere. On kbin, if installed using the instructions as-is, we're using rabbitmq (but there is an option to write to db). But failures do end up hitting sql still and rabbit is still storing this on the drive. So unless you have a dedicated separate rabbitmq server it makes little difference in terms of hits to storage.

It's hard to avoid storing them somewhere, you need to be able to know when they've been sent or if there are temporary errors store them until they can be sent. There needs to be a way to recover from a crash/reboot/restart of services and handle other instances being offline for a short time.

EDIT: Just read the issue (it's linked a few comments down) it actually looks like a weird pgsql reaction to a trigger. Not based on the number of connected instances like I thought.

r00ty Admin ,
r00ty avatar

Whose fault is it though? If an instance is capable of 100 concurrent users but everyone flocks to the two or three big instances. What to do? Block instances so they shutdown? Then when the shit really hits the fan there's nowhere to distribute users to.

In the case of lemmy.world I might suggest they split the instance. Original lemmy.world keeps the communities but has no users. Create a new instance and transfer the users. That way the first instance is dedicated to federating the communities, moving the real time user database hits to a separate database. I'd also suggest preventing the creation of new communities on that instance.

In real terms it'd have been better if the communities were shared between instances more. Making a more even spread of the one to many distribution efforts.

r00ty Admin ,
r00ty avatar

Yep I read through it in the end. Looks like they were applying changes to all rows in a table instead of just one on a trigger. The first part of my comment was based on reading comments here. I'd not seen the link to the issue at that stage. Hence the edit I made.

I mean you'll always be able to. In the same way you could use actual VHS recorders or film to get those effects. But it's far easier to apply the filters. Likely yes, such codecs won't be readily available and it might be more effort to do the real thing than add a filter. Who knows.

r00ty Admin ,
r00ty avatar

My opinion here is. Sure keep the valid stuff provided the user agreed to it. Have an opt-out though where data is analysed for whatever purpose then deleted. I don't know why they cannot keep data for a day, run analysis and delete on a rolling basis. The benefit of having old data to run improved analysis on is negligible when you're getting as much new data daily as they do.

But, regardless the excerpts it sends when it thinks you might have said the wake word which turn out to be false should be deleted. Do any short analysis for the why right away and delete. Because it really wasn't for the phone/personal assistant.

Until they redirect twitter.com to x.com and not the other way, and actually change twitter on the site, it's still twitter but with a new logo.

I suspect eventually he'll do that though.

I never quite understood the point of twitter though, so never had an account. I dare say there's less chance I'll get one now.

Well any instance owner could also get an onion link and host the instance over tor.

Of course the instance itself can't really hide. Since it needs to federate with others that are not onions. But your accesses would all show as from localhost.

In the UK right now it's actually cold for July. Overnights going as low as 7-9c in the south and day time max between 16c and 22c. So it might explain it.

So, yeah that's not the case that they could go outside and see for themselves. Yeah it's still a stupid conspiracy theory. But, there's no heatwave in the UK right now.

I was using linux for gaming until recently. I need to repair it, and also have been using some windows centric software. So booting mainly into windows right now.

But one thing I noticed was that on nvidia blob drivers at least (cannot attest to amd), in FPS games, where every millisecond does count. There's definitely a bit more latency on linux compared to windows. Enough to feel it for sure.

Otherwise almost everything (windows store games being mostly the exception) worked fine or could be made to run fine in linux and performance aside from what I am feeling as added latency was on par and sometimes better than windows.

People in Europe can easily buy cheap shit from wish.com and whatever that new one is and import them, also you'll get them on ebay from people that just importing in bulk. They will certainly have a nice FCC and CE sticker on them. But, no they're most certainly not certified!

Cheaply made non conforming electronics has been a thing for decades now. But until now it's generally been power supplies that pollute the radio waves with noise (and might go pop one day, but probably not cause a fire). Now we're messing with lithium based batteries without the proper safety circuits you see on property certified stuff. They can cause serious self fueling fires that are hard to put out.

In short, in Europe I would only trust something I bought on a retailer with a national presence and definitely NOT ebay.

I wonder about the optimizations now. When I used gentoo it was an era where binaries were compiled for lowest common denominator targets. i386, ppc etc. That is they used no optimized instructions at all. It was the era where MMX and SSE were becoming a thing and there were genuine optimizations you were likely missing out on. So compiling your own stuff actually did show varying levels of improvement.

These days I'm pretty sure most binaries are detecting cpu flags and flipping on extra functionality when detected so the optimizations are less pronounced than they were.

But, I'd be interested to know if I've got that wrong. These days, I've gotten older and I don't have time to spend a weekend fixing my system when it goes wrong, as such I'm using pre-compiled distros. Often when they break I'll fall back to my dual boot windows until I have a block of time to fix it. How did I have so much spare time back then?

The guys themselves made a pretty good write-up. https://lock.cmpxchg8b.com/zenbleed.html

The short version is that the very large registers on the modern CPUs aren't fixed things like they used to be, they're allocated from some register area on the die. When they "zero" the upper portion of one of the large registers it doesn't really clear it. It just releases the block back to available.

Another thing all CPUs need these days to keep fast is branch prediction. CPUs are only fast if they can keep the pipeline of upcoming commands (opcodes) to process full. So they often run both possible routes for a branch and discard the loser.

In this case they "trick" the CPU by asking it to "clear" a block of one of these large registers (the upper half). But then have the branch go the other way. What sometimes happens is that the register space is "released" but it has to take it back. In some specific circumstances they are able to have the register come back, but not with the original contents but with some random contents of maybe another register that was used by another thread (maybe even running on a different VM guest).

I have a server with a 3000 series CPU. I can confirm this definitely works. You'll get all kind of random blocks of memory from processes running as all users (and kernel code). For AMD processors running VM servers it is even worse. Because if you have say a VPS running on an AMD Zen2 CPU, you can login as any user run this and get random data from people on other VPS on the same hardware!

There is a linux workaround, and it seems most CPUs will be fixed by December.

Note: If you have access to a VPS that is vulnerable, do note that in most countries it is illegal to even try to exploit this.

Here's the thing. Most people into the federated alternatives aren't really going to the old place any more. I mean I'll admit I've been taking a look at r/place every now and then. But otherwise I'm not engaging with my usual haunts there. That's why there's not so many people to make a big impact on the canvas for any of the federated projects.

However there are still a lot of people still active that are unhappy with spez and his activities. Which explains why that message has a lot more traction there.

I thought there was a different redirect on ipv6 for a moment, maybe there was for a short time.

x.com on ipv4 maps to 104.18.16.213 and ipv6 maps to 2606:4700::6812:10d5 and that right now is a cloudflare server with a 302 redirect to "https://.twitter.com" most importantly is, SSL doesn't work on it. It fails with an ssl error on curl.

So, yeah. Quite a funny mess up.

r00ty Admin ,
r00ty avatar

Godaddy AND cloudflare. twitter.com doesn't use either, which coupled with the typo on the redirect makes this really feel like a very Musk initiated thing going on here.

I bet he's on the free tier of cloudflare too.
