  • I remember this sort of stuff a long time ago. There were wifi drivers that were either linux, but closed source, or horror of horrors having to resort to ndiswrapper…

    Of course, the Ubuntu derivatives made this easy enough by just including it, but Fedora was much more purist about open source and so wouldn’t even tell you about rpm-fusion, let alone enable proprietary drivers for basic network access.

    Now Fedora has edged a bit more practical and proactively let’s users know about how to add proprietary stuff and the wifi industry takes Linux seriously, if not for desktop use then for all the embedded use cases they would be left out of without good Linux support. Fedora is still a bit far on the ‘purist’ side still (try to play a lot of media using dnf provided software, it will tend to break), but not as hard as it used to be)


  • the TLS-ALPN-01 challenge requires a https server that implements generating a self-signed certificate on demand in response to a specific request. So we have to shut down our usual traffic forwarder and let an ACME implementation control the port for a minute or so. It’s not a long downtime, but irritatingly awkward to do and can disrupt some traffic on our site that has clients from every timezone so there’s no universal ‘3 in the morning’ time, and even then our service is used as part of other clients ‘3 in the morning’ maintenance windows… Folks can generally take a blip in the provider but don’t like that we generate a blip in those logs if they connect at just the wrong minute in a month…

    As to why not support going straight to 443, don’t know why not. I know they did TLS-ALPN-01 to keep it purely as TLS extensions to stay out of the URL space of services which had value to some that liked being able to fully handle it in TLS termination which frequently is nothing but a reverse proxy and so in principle has no business messing with payload like HTTP-01 requires. However for nginx at least this is awkward as nginx doesn’t support it.



  • Frankly, another choice virtually forced by the broader IT.

    If the broader IT either provides or brokers a service, we are not allowed to independently spend money and must go through them.

    Fine, they will broker commercial certificates, so just do that, right? Well, to renew a certificate, we have to open a ticket and attach our csr as well as a “business justification” and our dept incurs a hundred dollar internal charge for opening that ticket at all. Then they will let it sit for a day or two until one of their techs can get to it. Then we are likely to get feedback about something like their policy changing to forbid EC keys and we must do RSA instead, or vice versa because someone changed their mind. They may email an unexpected manager for confirmation in accordance to some new review process they implemented. Then, eventually, their tech manually renews it with a provider and attaches the certificate to the ticket.

    It’s pretty much a loophole that we can use let’s encrypt because they don’t charge and technically the restrictions only come in when purchasing is involved. There was a security guy raising hell that some of our sites used that “insecure” let’s encrypt and demanding standards change to explicitly ban them, but the bearaucracy to do that was insurmountable so we continue.




  • Ours is automated, but we incur downtime on the renewal because our org forbids plain http so we have to do TLS-ALPN-01. It is a short downtime. I wish let’s encrypt would just allow http challenges over https while skipping the cert validation. It’s nuts that we have to meaningfully reply over 80…

    Though I also think it’s nuts that we aren’t allowed to even send a redirect over 80…


  • So on mine, I haven’t bothered to change from the ISP provided router, which is mostly adequate for my needs, except I need to do some DNS shenigans, and so I take over DHCP to specify my DNS server which is beyond the customization provided by the ISP router.

    Frankly been thinking of an upgrade because they don’t do NAT loopback and while I currently workaround with different DNS results for local queries, it’s a bit wonky to do that and I’m starting to get WiFi 7 devices and could use an excuse to upgrade to something more in my control.







  • I think an ai could outperform my executives.

    One of them sent out an email about how we weren’t making enough money. But don’t worry, he has a strategy that we will execute on and fix it.

    The strategy is to raise prices and get more sales at the same time… That is literally it. Not even picking “high value” versus “high volume”, just a declaration that we can do both. If this genius plan doesn’t work, it’s just because the sales people failed to execute against his brilliant strategy well enough.


  • It’s pretty much a vibe coding issue. What you describe I can recall being advocated forevet, the project manager’s dtram that you model and spec things out enough and perfectly model the world in your test cases, then you are golden. Except the world has never been so convenient and you bank on the programming being reasonably workable by people to compensate.

    Problem is people who think they can replace understanding with vibe coding. If you can only vibe code, you will end up with problems you cannot fix and the LLM can’t either. If you can fix the problems, then you are not inclined to toss overly long chunks of LLM stuff because they generate ugly hard to maintain code that tends to violate all sorts of best practices for programming.


  • This all presumes that OpenAI can get there and further is exclusively in a position to get there.

    Most experts I’ve seen don’t see a logical connection between LLM and AGI. OpenAI has all their eggs in that basket.

    To the extent LLM are useful, OpenAI arguably isn’t even the best at it. Anthropic tends to make it more useful than OpenAI and now Google’s is outperforming it on relatively pointless benchmarks that were the bragging point of OpenAI. They aren’t the best, most useful, or cheapest. The were first, but that first mover advantage hardly matters when you get passed.

    Maybe if they were demonstrating advanced robotics control, but other companies are mostly showing that whole OpenAI remains “just a chatbot”, with more useful usage of their services going through third parties that tend to be LLM agnostic, and increasingly I see people select non OpenAI models as their preference.
