It’s sorta funny to see one of the companies aiming for terahertz frequencies - long wave IR is only ~30THz.

It'd be nice to see the 'terahertz gap' closed finally.

Not for a practical reason, but it's been on my mind since I randomly found a wikipedia article about it.


Interestingly reading the terahertz radiation wikipedia article they mention peeling adhesive tape generates 2THz and 18THz peaks

If only


This is incorrect - they can split however the driving chip supports. (Q|O)SFP(28|56|112|+) can all be split to a single differential lane. All (Q|O)SFP(28|56|112|+) does is provide basically direct, high quality links to whatever you chips SERDES interfaces can do. It doesn't even have to be ethernet/IB data - I have a SFP module that has a SATA port lol.

There's also splitting at the module level, for example I have a PCIe card that is actually a fully self hosted 6 port 100GB switch with it's own onboard Atom management processor. The card only has 2 MPO fiber connectors - but each has 12 fibers, which each can carry 25Gbps. You need a special fiber breakout cable but you can mix anywhere between 6 100GbE ports and 24 25Gbe ports.

There’s also a fairly decent wind storm coming in tonight - 45mph gusts predicted.

It’s going to be an interesting week in the Washington PNW…


I don't think we're going to get as much, but I do think those flooded could use some reprieve.


A full frame focal plane shutter _cannot_ work for medium format sadly. It's be definition too small. I don't think you can use them partially in front of the focal plane, but I could be wrong.

Medium format focal plane shutters do exist, copal made them for Mamiya/Phase One for their AF, AFD, DF, DF+, and XF cameras. Some of which work for medium format film.


Does it not? It feels like it’s taken seriously nationally.

All the local high schools in the Seattle area had/have serious jazz programs that sent students to The Essentially Ellington competition/festival - the one the movie Chops is about.

Seattle probably has the most overall bands sent of any city in the country. I guess we sent 4 this year - https://www.seattletimes.com/entertainment/music/4-seattle-a...


Buy amazon gift card in cash, setup new account, ship scratch card to locker? (Idk if they’d let you do that).

I think you can still mail them cash?


Can an Amazon account be made anonymously? (I've never tried).


I assume if all the inputs are anonymous you could? Like phone/email. Never tried either haha.


Yeah this tracks - if someone says something is “not great” it’s probably extremely bad haha. or “super cool no problems here” (there’s tear gas streaming through the windows)


Amusingly the lenses are worse than silicon at transmitting that wavelength.

1550nm might be worse for sensors because a good portion of the light is only being dumped into the metal layers - pure silicon is mostly transparent to 1550nm. Not sure how doped silicon would work. I can tell you that 1070nm barely works on an IQ3 Achromatic back…

The level of work that goes into even “small” games is pretty incredible. When I was a grad student another student was doing their (thesis based, research focused) masters while working at EA on a streetfighter(?) game.

The game programming was actually just as research focused and involved as the actual research. They were trying to figure out how to get the lowest latency and consistency for impact sounds.
