  • i don’t know, maybe softbank counted on openai not being able to go for-profit (which is not IPO, so it’s not like they got more transparent or anything). that deal was signed long time ago in bubble terms, and it went like this (or so i heard): first tranche was 10B from softbank + up ro 10B from other investors, they couldn’t get all that money from other investors and that’s why it was 18.5B and not 20B. that was some half year ago? even back then softbank didn’t had the money and had to sell part of arm (iirc). now they had to supply the remaining 22.5B, idk if it’s all softbank, or whether they would get out of that deal if they could, or whether they will continue pouring money there (we can assume all these dcs are vaporware) can openai find other suckers? possibly, but scaring away a reliable one would be bad for business









  • Mate do i have just the right thing for you, but it requires some soldering. It’s also probably cheapest solution working over longer range than you need

    First you need two directional antennas. Use this https://lea.hamradio.si/~s53mv/wumca/cup.html the 13cm design specifically. Design of the dipole element is on another page https://lea.hamradio.si/~s53mv/wumca/sbfa.html They’re using hard to get semirigid coax but you can really just use common RG178 with braid tinned to make it stiff. This way you don’t have to leave D section they way they did, you can just solder core to the shield at the end while preserving total length (or ~1-2 mm less, because wifi is slightly higher frequency; 53-52 mm total). That dummy cable thing can be just any stiff piece of wire. Good way to get this would be getting a pack of u.fl-SMA pigtails, which you can also use for connection.

    You also don’t need special aluminum housing like they do, cookie tin of the right size would be sufficient, or any other container of similar nature. If you can’t weatherproof it, putting it inside on windowsill is also fine

    Then, plug TL-WN722N into it, or some other single-antenna thing, and you’re set. This one connects over USB and has removable RPSMA antenna, so you can connect it easily with correct cable (SMA plug - RPSMA plug)

    to your new directional antenna. This thing works well over 200m distance, provided clear line of sight, and probably more than that



  • here if you need anything over certain power (6kW; depends on country i guess) you need a three phase installation, and even if you get single phase, it’s really handled as three phase split between single phase customers (a block gets three phase supply, then splits flats in three groups, each group gets connected to one phase). this gets supplied by a distribution transformer that might serve somewhere around 200 people per (in residential areas)

    i understand that sometimes americans also get distribution like this, with 208/120 three phase coming from substation, without 240v available
