johncolanduoni··on Cloudflare Down Again – and DownDetector Is Also Down
We need a set of down detectors that all detect if each other are down, and produce an answer via quorum.

I always suspected RSC was actually a secret Facebook plan to sabotage the React ecosystem now that their competitors all use it to some degree. Now I’m convinced.
johncolanduoni··on Cloudflare Down Again – and DownDetector Is Also Down
All the big companies embraced vibe coding, so I’m not sure there was a natural experiment here.

Maybe the little plane icons on the ATC screens are a PNG hosted on some Cloudflare domain.

Did anybody, including the rightsholders, come out ahead on H265? From the outside it looked like the mutually assured destruction situation with the infamous mobile patents, where they all end up paying lawyers to demand money from each other for mostly paper gains.

For wireless, the prices aren’t much different from products with comparable feature sets/performance. For some niche combinations, they’re the only option that doesn’t force you way upmarket (Meraki, etc.). Most of the money they make is from small business and tiny WISPs, not HN boosters overdoing it on their home WiFi in what must be a bid to get their partner to divorce them.

Their wired stuff is a total scam since Edgerouter fell off, though. The same functionality exists on a $50 netgear managed switch (or wired router, etc.), and the shitty unified configuration interface doesn’t justify the markup at all.

johncolanduoni··on UniFi 5G
Sure, but it’s not manufactured in Ch- ah, nevermind.
johncolanduoni··on UniFi 5G
The controller is annoying and changes completely every 6 months, and for home I use basically none of its features beyond configuring the AP. Virtualy all the issues I’ve had with Unifi APs were controller bugs, telling the AP firmware to do stupid things when it could have done literally nothing.

That said, I have some concerns that the OpenWRT AP firmware is not as optimized as the Unifi firmware is for that specific hardware. Mostly for wireless performance, but I also don’t want to hit some weird CPU bottleneck.

And for most of the people here, buying any 5G mmWave modem is a questionable investment.
johncolanduoni··on UniFi 5G
This ship sailed out of view a long time ago, the only GB you’ll see that is still base-2 is RAM. And that’s only because you literally can’t address physical RAM in non power-of-2 blocks in most architectures.

If you really want to piss people off, use Gibibits - 1024 * 1024 * 1024 bits. The ratio between those and Gigabytes is ~7.451.

Are motherboards commonly using PCIe 3.0 for onboard peripherals these days? I wouldn’t expect it to save them much money, but my PCIe knowledge is constrained to the application layer - I know next to nothing about the PHY or associated costs.
johncolanduoni··on UniFi 5G
Is OpenWRT on Unifi APs any good? I hadn’t heard of it before, and I couldn’t find any performance comparisons on a quick search. Ubiquiti has gone downhill on a lot of things the last 5 years or so, but their radio firmware has always been a step up (within their price range) for me. I wouldn’t mind ditching the Unifi controller software though.

I’m sure it depends on the model, but in my experience if you force a 10G copper transceiver to 2.5G the insane heat generation goes away. I don’t have any Thunderbolt 10G adapters, but I’m kind of surprised they’re much larger. A SFP+ transceiver is the same size as a SFP one.
johncolanduoni··on UniFi 5G
40G on Mikrotik is just channel bonding of 4 10G links at layer 2. It’s not like the vast majority of 100G that does layer 1 bonding. I really don’t know why they did it other than to have a bigger number on the spec sheet - I can’t imagine they save any money having a weird MAC setup almost nobody else uses on a few low-volume models.
johncolanduoni··on UniFi 5G
This is a modem, it itself is the client of a cell tower/base station. So unless you put it in a faraday cage with the base station next to it, 2G is almost certainly enough.

The better reason to put a 10G transceiver in this would be that some (cheap, honestly garbage) SFP+ transceivers can’t negotiate anything between 1G and 10G. But I’ve only seen that on bargain-bin hardware so I don’t know that they should be designing products around it.

johncolanduoni··on Russia Bans Roblox
None of the Russian expats I’ve met had this problem: after 2014 they all saw the writing on the wall and moved their money to western banks. I have sympathy for those that didn’t - normal people shouldn’t have to make this kind of calculus - but there’s no alternative to this while having useful sanctions. It’s not the causeless brutality of breaking someone’s window because of their accent.

Glad to see software engineers aren’t the only ones that count lines well past the point that they should be.

Compression gains will mostly be for the benefit of the streaming platform’s bills/infra unless you’re trying to stream 4K 60fps on hotel wifi (or if you can’t decode last-gen codecs on hardware either ). Apparently streaming platforms still favor user experience enough to not heat their rooms for no observable improvement. Also a TV CPU can barely decode a PNG still in software - video decoding of any kind is simply impossible.

Not everything that glitters (or blinds) is gold.

I wonder if it fundamentally only really makes sense for film, video games, etc. where a person will actually tune the range per scene. Plus, only when played on half decent monitors that don’t just squash BT.2020 so they can say HDR on the brochure.
johncolanduoni··on OpenAI declares 'code red' as Google catches up in AI race
If the AI boosters are right about what the technology will be capable of in 5 years, at least some of the big player’s investments will be literally the most profitable investments that ever happened. This is a potential mispricing, not a system inherently incapable of paying off long term like the subprime mortgages were. I don’t think another step-change like we saw with GPT2/3 is likely in the mid-term future, but I don't think anyone has shown it’s virtually impossible.
johncolanduoni··on Russia Bans Roblox
They’re referring to sanctions - persons/businesses residing in Russia, certain specific individuals and those working for specific Russian entities are locked out of much of the Western economy. I think it’s reasonable personally, but I can understand how a Russian 1000km from the Ukrainian frontline who used to sell jewelry on Etsy would be pissed.
johncolanduoni··on Russia Bans Roblox
Not all governments are equal - though this cuts both ways.
johncolanduoni··on Russia Bans Roblox
Not all sanctions only require you to validate that the bank isn’t from that country. Usually disbursing money (which Roblox does as a two-sided marketplace) requires actual KYC.

Some stuff on Roblox is free, perhaps they were only enjoined from accepting payments?

VPNs on cheap VPSes are blocked quite a lot too.

In a narrow sense, it did move along the story point at the end of HL2 (I won’t explain how because there’s no way to do so without massive spoilers). But yeah, it would be weird to call in HL3 just because of that.
johncolanduoni··on OpenAI declares 'code red' as Google catches up in AI race
Oh I don’t doubt any of this - it’s just that you don’t usually see the CCP publicly making arguments that they need to sacrifice the long term for the short term. They have a brand for how they public ally justify their decisions, and it’s definitely about the inevitable, long arc of Chinese history of whatever.
johncolanduoni··on IBM CEO says there is 'no way' spending on AI data centers will pay off
Commercially, Watson was a joke from beginning to end. If their argument is that Watson’s failure indicates a machine that can at the very least convincingly lie to you will definitely fail to make money, that’s an insipid argument.
