It’s specifically implied? :P

When I was talking about memory, I was more thinking about how it is accessed. For example, exactly what actions are atomic, and what are not on a given architecture, these can cause unexpected interactions during multi-core work depending on byte alignment for example. Also considering how to make the most of your CPU cache. These kind of things.

I’d agree that there’s a lot more abstraction involved today. But, my main point isn’t that people should know everything. But knowing the base understanding of how perhaps even a basic microcontroller works would be helpful.

Where I work, people often come to me with weird problems, and the way I solve them is usually based in low level understanding of what’s really happening when the code runs.

I’ve always found this weird. I think to be a good software developer it helps to know what’s happening under the hood when you take an action. It certainly helps when you want to optimize memory access for speed etc.

I genuinely do know both sides of the coin. But I do know that the majority of my fellow developers at work most certainly have no clue about how computers work under the hood, or networking for example.

I find it weird because, to be good at software development (and I don’t mean, following what the computer science methodology tells you, I mean having an idea of the best way to translate an idea into a logical solution that can be applied in any programming language, and most importantly how to optimize your solution, for example in terms of memory access etc) requires an understanding of the underlying systems. That if you write software that is sending or receiving network packets it certainly helps to understand how that works, at least to consider the best protocols to use.

But, it is definitely true.

I’ve used IPv6 at home for over 20 years now. Initially via tunnels by hurricane electric and sixxs. But, around 10 years ago, my ISP enabled IPv6 and I’ve had it running alongside IPv4 since then.

As soon as server providers offered IPv6 I’ve operated it (including DNS servers, serving the domains over IPv6).

I run 3 NTP servers (one is stratum 1) in ntppool.org, and all three are also on ipv6.

I don’t know what’s going on elsewhere in the world where they’re apparently making it very hard to gain accesss to ipv6.

The subject of how humans might perceive four dimensional space is covered in a later book of three body novels (Remembrance of earth’s past series). The author describes is as being able to see into sealed three-dimensional objects as if they had an open top. As such you could easily traverse into sealed rooms etc from such a perspective.

I thought it was quite an interesting idea.

Pics AND/OR it didn’t happen.

But I’ve never played smash. What does that mean? Oh! Oh.

An array?

var turtles = new Turtle[] { new Turtle(), new Turtle() };

Don’t do this :P

Nothing to do with pets, but in Korea there are places that serve dog. At least it was the case when I was there 20+ years ago. But, of course they’re not pets, they’re farmed like any other livestock I would expect, and these places were not exactly commonplace even then, so maybe now they’re just not a thing? I’ve not really looked into it.

Now, saying “x” people eat pets is likely just what others have said, a slur used against whichever subset of people is the target of the month. Maybe it once had roots in facts like those I’ve mentioned, but they’re far removed from them now.

No, I did not partake in eating dog.

I mean for advert breaks, there are projects to do this to recorded tv automatically (with varying degrees of success depending on the config and the channel).

That is, you record the TV from either a TV receiver card, or streamed live channels to disk, then run this process on the mkv/mp4/ts, and it will either create a set of chapters marking the ads (so you can skip them), or it will just remove them entirely.

I don’t think it would transfer to “live” TV quite so readily though. Because it does scan the whole program to find things like logos etc to help work out where the adverts are. But, I mean a lot of the work has been done.

For removing all product logos. I mean, I bet we’re not far from the processing power to make it possible. But, probably a fair bit of effort needed.

I can imagine the “AI” chips being neutered for these kind of tasks, like the “low hash rate” Nividia cards.

Ah, so the kind of crypto bro, that instead of a fistbump, does a diffie-hellman key exchange instead?

When you post in a thread you get an ID for that thread. When you post in a different thread you get a different id.

That’s what I said. You don’t need any ID to federate the messages. If you reply to a comment the nesting is based on the comment/post ID and not the usernames.

You couldn’t track a users posts after the fact, and I think that’s kinda the point.

Not so sure that’s true though. If you look at a 4chan threads in some boards, you can recognize the individual anonymous’ from the ID next to them.

I suspect it’s using either a cookie, or the IP address to track a user and while not storing that info, generating an ID hash from perhaps a unique ID for the thread + their details.

No reason you couldn’t federate using the same. But, even without that, each post and comment has a post ID and replies would be tracked that way. Just, you’d need to remember which replies were your own.

The home instance could store for a thread some info about posts/comments from an IP or cookie too and highlight them. But that info wouldn’t be federated.

I actually don’t think it’d be a problem, really. But, is this something missing from our lives? I’m not so sure.

I did think of a few ways round it (in kbin/mbin) a year or so ago. But, it wouldn’t work unless everyone using ActivityPub recognized it. It’s also really a small problem in reality. It’s likes and dislikes.

I used to write z80 asm without an assembler back when I was a LOT younger. The ZX spectrum manual I had, had the full instruction list with the byte values.

I think it was oddly easier than some higher level languages for some tasks.

But, making changes was an utter nightmare.

I find anything with that coated plastic over time gets crappy. I still have an old X52 pro I’ve had for probably around 15 years now. In the end I just completely took off the flaking rubber style coating they put over it and it’s now shiny plastic and still going strong.

I also have a G502 that’s 6 years old. It has some worn areas where it’s actively held and on the buttons. I replaced the skates last year and have a spare set. Otherwise, still going strong.

Really not sure why I’d subscribe for something that lasts so long and isn’t THAT expensive to replace.

I’m going to blame the cloud for this. SaaS has got pretty much most software companies into the idea that they can have their cake and eat it with recurring revenue from cloud hosting their services.

This seems to have overflowed into every other market, where they want a piece of that pie.

I’m hoping it’s a fad that goes away. You know how we can make it a fad that goes away? Don’t buy into this shit.

Well good news. Because ipv6 has a thing called privacy extensions which has been switched on by default on every device I’ve used.

That generates random ipv6 addresses (which are regularly rotated) that are used for outgoing connections. Your router should block incoming connections to those ips but the os will too. The proper permanent ip address isn’t used for outgoing connections and the address space allocated to each user makes a brute force scan more prohibitive than scanning the whole Ipv4 Internet.

So I’m going to say that using routable ipv6 addresses with privacy extensions is more secure than a single Ipv4 Nat address with dnat.

Weird. Ipv6 and YouTube stats for nerds shows between 140mbit and 600mbit depending on what’s being watched and the time of day.

Is it possible your isp has problems with their ipv6 setup?

IPv6 overheads should only have a marginal impact on max speeds.
