  • I just discovered how easy ollama and open webui are to set up so I’ve been using llama3 locally too, it was like 20 lines in docker compose, and although I’ve been using gpt3.5 on and off for a long time I’m much more comfortable using models run locally so I’ve been playing with it a lot more. It’s also cool being able to easily switch models at any point during a conversation. I have like 15 models downloaded, mostly 7b and a few 13b models and they all run fast enough on CPU and generate slightly slower than reading speed and only take ~15-30 seconds to start spitting out a response.

    Next I want to set up a vscode plugin so I can use my own locally run codegen models from within vscode.





  • I only do web development, but my networking knowledge mostly comes from being the designated person to call the ISP for tech support and being in charge of setting up the WiFi in every place that I’ve lived, in addition to participating and running community scale mesh wifi tech meetups for many years (think NYCMesh except just 4 guys who never accomplished much aside from buying and flashing lots of routers with openwrt lmao)

    I also ran 12Us of homelab for a few years in my basement, which was powered by an overkill fiber to the home setup (courtesy of tricking Comcast into undercharging me for gigabit pro) that necessitated a 10G switch and firewall.


  • Your ISP knows the Mac address of your router since it requests a public IP from them using DHCP. That’s why if you contact support they usually can confirm the brand of your router by doing an oui lookup.

    In theory the FBI could have collected a list of MACs and optionally used an ASN lookup on the public IP and then handed each ISP their list of MACs, which the ISP could associate back to customers to contact. It would only not work for customers who spoof their router WANs ethernet mac.

    But I think just patching it is a normal and fine solution imo.



  • I’m more excited about reducing congestion when more of my neighbors upgrade to 6, so that BSS coloring and other wifi 6/7 features can enable more efficient use of the spectrum. Before wifi 6 most of the upgrades were just increasing data rates, but really lacking in improvements to spectral use efficiency (like the resource unit allocation in OFDMA which splits channels into sub carriers and centrally plans assignment to multiple client devices for simultaneous use which results in much less wasted airtime compared to each device yelling and listening while waiting to see if they can have exclusive access to the whole channel which wastes time) and interference management (like preamble puncturing which allows partial use of a channel when only a portion has interference). In a crowded environment like an apartment building wifi 6 should help a lot in reducing channel utilization.


  • It feels like the rollout of client modules and APs/routers was better synchronized this time. Back with wifi 6 I ordered the Intel modules within a week of them being available on AliExpress and then waited for what felt like months for APs to be available (it looks like unifi’s wifi 6 ap finally came out in November 2021 based on when I bought it). Unifi’s U7 pro dropped a few days ago so I nabbed one as soon as I saw the email and that arrived today so that’s already set up, and the wifi 7 modules have already been out for a bit, i just didn’t order them since I was anticipating a wait for APs. So now I just gotta wait a bit for shipping and I’ll have all my laptops upgraded too.



  • What do you mean no? Everything I said is true - I’m just describing my firsthand impression. Nowhere did I say transparent aluminum is a type of glass? I was just describing why it feels heavier and colder than you would expect since it looks like glass, of which most are less dense and less thermally conductive compared to transparent aluminum, which is not glass but makes sense to compare to in order to convey what handling a piece feels like.

    Transparent aluminum is so weird, a piece of it was once passed around our office. It felt heavier and colder than I expected, which I guess is probably because it’s much denser than most types of glass (I think it’s only comparable to optical glass so it would be close to holding a high quality glass lens) and it looks like the thermal conductivity is way higher.
