If you follow (even if loosely) the APNIC blog, you've surely came across Geoff Huston's articles. ✍️https://blog.apnic.netI strongly recommend this episode from APNIC's PING podcast where Geoff explains BGP RPKI, and ends up almost making the case *against* it (and IPv6 too).Given he usually covers both topics in a very positive way, I found it awesome how this time he makes you look at these problems from another angle. https://blubrry.com/ping_podcast/90735961/whither-rpki/#apnic #bgp #rpki #ipv6

What I found really interesting, for IPv6 in particular, is the (implicit) notion that we can keep advocating for something over decades using pretty much the same arguments, while the real world changes in ways that make those arguments irrelevant.But that doesn't mean we suddently don't need IPv6. In fact we need it just as much as before, but the most important reason(s) are now different.#ipv6 #advocacy🧵

We may have to face the fact that end users don't care about IPv6 and maybe never will. They don't care if their devices have a globally routable address. And care even less every day as technically unpalatable stuff like CG-NAT (not giving customers a public IPv4 address at all) sets in without triggering the apocalypse.So, if in a few decades we conclude that killing IPv4 is impossible, we should at least say we're still using it only where it's OK, and IPv6 everywhere else.#ipv6 #advocacy

@ceresbzns And it's especially sad when ISPs deploy CG-NAT to fixed connections not because they're out of IPv4 addresses, but because they can't manage the ones they have properly (e.g. geographically or stealing them from the mobile side).

@tschaefer @ceresbzns Even though that may be true for most cases, I've heard of CG-NAT deployments happening because the ISPs can't reassign large ranges of unused IPv4 addresses because of the way they structured their network in the past. That's why I said "especially sad".

@tschaefer If that's what the Internet is becoming, shouldn't the fight for the preservation of a global unicast Internet take that into consideration, and shouldn't we update the way we advocate for it?What other arguments can we use in favor of IPv6 that aren't met with the same shrugs that we've gotten from many ISPs over decades?If there's no clear answer, we may be doomed. 😔

@tschaefer We may not like it, but what used to be temporary workarounds until we have IPv6 everywhere have become competing solutions to IPv6 itself.I'd like to see some numbers on how many mobile ISPs deploy CG-NAT when they run out of IPv4 without deploying IPv6 at the same time. That may be an indicator of the kind of danger we're in.

@tschaefer On the other hand, in Portugal the largest ISP (3243) has had an almost full IPv6 deployment for years on its fixed service.The other largest (2860, roughly as large) has just started ramping up IPv6.Both do CG-NAT on mobile, neither provides IPv6 there (just checked).Vodafone PT also deploys IPv6 to ~60% of its customers but I can't confirm their IPv6/CG-NAT status on mobile.Why is it they seem to be interested in deploying IPv6, but not at all on mobile?

Users of RHEL clones aren't freeloaders, but that doesn't mean there aren't any freeloaders around.Oracle, SUSE, and CIQ are recreating United Linux 21 years later, but now it isn't about creating a distro to compete with Red Hat, it's about ensuring they can keep selling support contracts on top of 1:1 RHEL clones.https://openela.orgThis just makes @almalinux look like the torch bearer for the original CentOS "spirit" and the better choice if you prefer the Red Hat flavor of Linux.

When observed from the outside, #retrocomputing may appear driven by escapism from modern technology and nostalgia for simpler times – which isn't false, really, and there's nothing wrong with that – but that doesn't mean it's backward-looking.There's so much new stuff being done in this area, from software-defined ISA cards to FPGA-based reimplementations of old chips and whole-system emulation.And there's so much to learn from older, simpler, systems that can be applied to modern problems.

There's a small retro exhibit at a nearby mall. Not the most exciting of places, but it does cover a broad audience.But... sigh.At least put a piece of paper next to the items with their names/descriptions. When interactive, add some instructions."Oh my $DEITY! Old games looked so bad!"Don't put old systems on display using LCDs. Their scalers are terrible. No one experienced such an awful image quality back in the day, not even RF with the cheapest of TVs.#retro #retrogaming #lisbon

There was a TurboGrafx-16 there running "Blazing Lazers" (1989), also called "GunHed" in Japan.The TurboGrafx-16/PC Engine is very rare in Portugal. Collectors may have them now, but it was unheard of back in the day.Blazing Lazers is a good looking game, with a very arcade-like experience (in gameplay and smoothness).I could've spent a while playing it, but walked away after a minute due to the terrible LCDs.I didn't see anyone else playing it. What a shame.#retrogaming #retro #lisbon

1942, 1943, 1941, 14xx is a series of vertical shooters by Capcom, released in 1984, 1987, 1990, and 1995.Spanning 11 years across 4 arcade boards – the Zilog Z80-based Capcom Z80 / Capcom Commando, and the Motorola 68000-based CPS-1 / CPS-2 – they illustrate the evolution of the underlying hardware quite nicely.And even if 1942 and 1943 don't look much different, the latter sounds much better.It's also curious how, being japanese games, the enemy is Japan.#retrogaming #history #arcade

The series had an additional title released in the 20th century: "1944: The Loop Master" (2000).It's still on Capcom's CPS-2 hardware, but was no longer developed by Capcom. Also, it no longer uses a vertical aspect ratio, although it's still a vertical shooter.It's quite nice. 💯#retrogaming #arcade

It depends on one's taste, of course, but some 80's systems have aged better than others regarding games.The ZX Spectrum was very limited – low-res, color clash, harsh beeps – yet most games retain some charm. Even if they don't draw me in for long.The CGA era of the IBM PC doesn't click for me, though. Those magentas and blues in Alley Cat (1984): not my colors.Even the early EGA era... Look at Gauntlet (1988). My eyes... they bleed. 😬#retrogaming #msdos #zxspectrum #pixelart

@Wintermute_BBS Monochrome monitors do make these games look better (sadly doesn't turn Gauntlet for DOS into a better game).@arroz Art is key – whether artists made the best out of the limitations. That's what I meant with "early EGA era" because there were some good looking EGA games later on, like Loom (1990).Higher resolutions also made up for less colors on the PC. Just look at Syndicate with its mere 16-color palette (albeit not the fixed EGA palette).#retrogaming #msdos #pixelart

Retro enthusiasts get upset that vintage hardware has become (relatively) expensive. I think that isn't such a bad thing.Yes, it's distasteful to see a high price tag on something the seller probably sees as rubbish, but maybe having monetary value outside the retro community will help these things remain around for longer.Because, when those who currently pay those prices for sentimental value inevitably die, maybe their heirs won't just e-waste it all.#retrocomputing #preservation

There are also benefits to vintage hardware having (reasonable) monetary value within the retro community itself. Specifically, discouraging non-reversible or high-risk mods.If modding an old machine makes it more likely to be used, that's great — there's less incentive to keep display pieces in working condition.But these things aren't being made anymore. Don't hack them away or go YOLO on them, unless they're really too far gone as original exemplars.#retrocomputing #preservation

For example...I own a PAL Mega Drive model 1 that I rarely use because I have no nostalgia for the lesser experience of PAL games.I *will* mod it to 60 Hz. I just don't want to drill any holes. Not even melt the original LED out like most off-the-shelf mods want you to do.If you have an Amiga that's worn from use, just clean it. But if it's too bad from sitting in an e-waste pile, by all means paint it fuchsia instead of putting its original case in the bin.#retrocomputing #preservation
