Another interesting thing about WW2 mail - they would photograph letters onto microfilm, then reprint them on the other end to save valuable shipping capacity.


What did a printer look like in WW2?


You didn’t really need a printer per se.

> Portable readers are plastic devices that fold for carrying; when open they project an image from microfiche on to a reflective screen. For example, with M. de Saint Rat, Atherton Seidell developed a simple, inexpensive ($2.00 in 1950), monocular microfilm viewing device, known as the "Seidell viewer", that was sold during the 1940s and 1950s.

Apparently that’s not what they really used for mail in WW2, though. This video shows how it was really done.

If your phone supports WiFi calling and dual SIM, you can get a data-only eSIM for the country you're visiting and you'll receive texts for your primary line over the data connection of the secondary eSIM.


Although they don't offer TOTP, I've noticed growing support for Passkeys which is a step in the right direction.


It is not a win. In a recent study, Robinhood with Citadel has the worst price improvement (execution quality) of any brokerage on the market. I’ve personally observed this - Robinhood might “improve” by 1/10 of a cent from NBBO while Fidelity is frequently closer to the mid.


How is that not a win? Robinhood customers still got better execution than NBBO. If you don't like Robinhood getting a tiny kickback here, you're free to go to another brokerage.


This is just noting that different brokers give different performance

That doesn't really have anything to do with pfof (TD Ameritrade gives better execution and receives pfof)

Presumably a market maker would pay (PFOF) slightly more to deliver slightly worse execution (keeping the spread).


Sure that sounds plausible but it's literally not what happens in practice (see the other comment I linked that discusses research on this very thing)


Yeah, I've seen the Levine column on it.


I was about to donate until I read things like this and their initiatives like promotion. The incentives are all wrong - donations should go to actual expenses (hosting, hardware, dev meetups, bounties on large contributions), not amassing influence. Wikimedia is an example of everything wrong with not-for-profits, not a model to emulate.

What if we could direct donations to specific components of KDE? I have some longstanding bugs I’d be happy to pay someone to fix.


Primarily because it has specialized functions for various matrix sizes which are selected at runtime.


Ok, so are you saying it contains mostly straightforwardly generated code?


I think the easiest way to do this is get a used sata drive from a name brand, and a usb to sata adapter.


I use the Intel P4510 (8TB) and have been super impressed with the performance. I also have some older WD SN200’s that are excellent MLC flash. You do need some active cooling for these types of drives such as in the path of a fan.

As for controller I’ve had good luck with this one: https://www.aliexpress.com/item/2255800570197081.html


You can run 4x32 DDR5 on current gen AMD consumer platforms but don't expect speeds above 4400MHz in quad-channel regardless of what the module is rated for. I'd instead suggest dual channel 48GB DIMMs for 96GB at full speed.


4 DIMMs does not equal Quad-channel. I see in AMD's presentation Quad-channel is supported by chipsets, but I am not aware of a current AMD consumer/hedt chip with 4 memory channels.


Non-Pro Threadripper 7960X/7970X/7980X are Quad Channel. (The Threadripper Pro's are Octa-Channel)

But yeah, Desktop Ryzen's are all Dual Channel.


True, but the Threadripper requires the TRX50 platform, so I still don't understand what is operative about the statement that the X870E chipset supports quad channel memory.


Good point. Makes me wonder if they'd consider a Threadripper version that uses that chipset, since the Non-Pro Threadripper have been in a weird spot ever since Ryzen went up to 16 cores. An AM5 Threadripper might not make sense because one of the appeals were the much bigger amount of PCIe lanes, but I wonder if they would pair the X870E with a new socket for Zen 5 Non-Pro Threadrippers.


A Threadripper with 24-32 cores but only 2 channels of memory, that worked in the AM5 socket, would fill a nice hole in the AMD story. I don't know if AM5 has enough power pins to do the job, though. If you want more than 16 cores right now you have to spend $2k on the CPU and motherboard, triple what it costs to get a 16-core Ryzen.



That's wild. Googles processes ensured many adults got to see this mans sons penis, many more than would have otherwise.
