"It costs about £900 in the UK to have an EV charger installed by an electrician" £900 is $1140. In southern California, it cost me $750 for top notch work and hardware, including: $400 to have an electrician install a 240V 50A

"what to regurgitate based on what it's already seen" ...which is no different than what humans do :-) Our neurons fire in a way only because they fire in patterns they have already seen before.

There is a lot of empirical evidence supporting the effectiveness of masks against COVID-19, and I would not call it weak. In my own quest for actual research instead of single data points ("I never mask and have never gotten COVID&quo

Isn't JLCPCB's turnaround time even slower than OSH Park, for shipping to the US? I know JLCPCB advertises "24h build time" but that's just physical manufacturing. The shipping is at least 4-5 days(!), as per the la

I too believe the company has entered a phase of stagnancy or even decline. In fact, so much that two weeks ago I put my money where my mouth is by selling $1M worth of GOOG I was given as part of a stock grant when I was hired by Google in

"main value is buying and selling illegal goods and services" Nah. Far more people use crypto for speculation than for actually illicit purposes.

Oh, right, not 1k LUTs. But toward the $120 range, such as the Digilent Arty S7 listed in the post, with 23k LUTs, it's likely possible to implement SHA256 cracking or mining and beat a CPU or GPU in performance/watt. Probably not

It saddens me that a browser consumes one and a half CPU cores to render a measly ~300x60 characters at 30 fps. Manipulating even just text in the DOM has so much overhead... That's on Linux with the latest stable Chrome on hardware le

Their math is erroneous. They claim at, 300 dpi, a capacity of 300,000 analog images, per letter size sheet of Nanofiche, and at 600 dpi a capacity of 150,000 images. But the jump from 300 to 600 dpi requires four times (not two times) the

I agree, GPUs can still generate more token per second per dollar, but what is new and great about the high-end M1 and M2 is Apple offering this much memory bandwidth on a general purpose CPU, thus immediately available to all software ru

by mrb 3y ago
For those wondering why the M2 Ultra is so fast, or the M1 & M2 series in general, it's because inference's main bottleneck is memory bandwidth, not compute power. And the M2 Ultra has a bandwidth of 800 GB/s which is abo

Strange metric indeed. "As much as a small country" is about as useful as saying "as big as a small rock".

The house numbered "9156" is most likely a data entry typo where two digits were swapped, and the correct number is "1956". That would make sense especially because the other house number are "below 2000" as th

Think about the number of pets doing this at, say, 20:07, and owners not realizing the time accuracy because it's not a round number of minutes after the hour.

Thanks, I'll check Infuse. It's weird that the other commenter claims Apple TV can passthrough DTS.

by mrb 3y ago
Do you have media with DTS (not Dolby) 5.1 audio tracks, and can Jellyfin pass it through from the AppleTV to your TV or A/V receiver?

Thanks, I will look into it !

I agree, Kodi requires constant maintenance and tweaking. Jellyfin seems better overall(?) But I'm really frustrated with this transcoding issue. Or the fact it's incapable of DTS 5.1 passthrough on GCCWGTV (even their site https

Sorry for the rant, but as someone who has used Jellyfin and similar apps like Kodi, I have to say I find their code quality and general software architecture to be crap. I wish there was a good alternative. A few examples: I have installed

I know it's 260 options, but I wrote "26k" as it's the right to buy 26k shares (1 option for 100 shares), for consistency with the parents who wrote 550k, meaning 5500 options to buy 550k shares.

Thank you. I am shocked everyone blindly trusts the "$22,000" amount without actually reading the screenshots.

Important note: he didn't buy 550k options, he bought 26k, for a total profit of $475k. The tweet is incorrect. See https://news.ycombinator.com/item?id=37602079

by mrb 3y ago
You are correct. The amount "$22,000" purchased options quoted in the tweet is not supported by the screenshots which show 260 options were purchased, for a total of $1,040, which is now worth $475k. See https://news.yc

No, the trader bought 260 options. See second photo in the tweet, first row, column "volume". 260 options times $4 equals $1,040 invested, which turned into $475k.
