The breakthrough was already announced by LLNL and discussed in https://news.ycombinator.com/item?id=33945863

For people in the Bay Area, there's one of those towers/installations in Redwood City, it's a large concrete tower there. It's now a data center building. It still has the microwave horns in it. [1]

This is for Manifest V2 (browser extension API that has been generating a lot of debate) and not some Mountain View office footprint expansion like I mistakenly thought out of context.

Kurzgesagt has a good cute video on the topic (tl;dr you need a lot of Falcon 9s) https://www.youtube.com/watch?v=Us2Z-WC9rao

The exciting part for me to play with is Linux GUI apps now can run on WSL on windows 10 (previously only supported win11)

> The microreactor can generate 5 MW of electricity or 13 MW of heat from a 15 MW thermal core. Exhaust heat from the power conversion system can be used for district heating applications or low-temperature steam.

They are aiming 8 years planned service life, and one novel thing is the use of heatpipes (like your CPU cooler) using liquid metal as a working fluid.

They actually don't say how big it is, I guess still quite sizeable given the heat output. Definitely not a single-family home device.

And yet, the "music stats" thing still has some appeal to some, when a lot of people I know post their Spotify "year in review" at the end of the year on IG stories.

I think it's because as the rider is leaning forward to indicate a desire for forward motion, the board drives the motor to move you forward, but also counters the natural tendency of the front lip to just touch the floor. If the motor cuts off while you are leaning forward, the lip will immediately hid the floor and stop you. And your muscle memory isn't expecting that kind of balancing, having been used to the board "fighting you back" on leaning forward too much.

The "universe map" with the artefacts is a mobile app only feature. [1] The browser version just has an ending choice that lets you restart with slightly different variables (in my case it was 10% higher demand)

A lot of adult creators moved to Twitter when Tumblr closed. Given what's happening there right now, it may not be the worst timing for Tumblr to again offer their platform as an option.

The button has always been there for me (unless the video maker disabled it) just without a counter. There is an extension that tries to crowdfund/estimate dislikes for youtube videos but who know how correct their data is [1]

For context, the RTX4090's power budget is 450W, and if all 4 plugs are connected to the cable adapter, the system can allow up 600W (at 12V) to the GPU. That's 6A to 8A per pin (there's 6 pins for current, 6 for GND plus 4 signaling pins), so pretty sensitive to resistive heating in case of a bad contact.

This points to a subreddit about a tool called venturapatcher if others were confused like me. I expected the link to take me to an intro post or something similar instead.

Link is behind a paywall, do you have an archive.is link?

CR2032 batteries that are in airtags are NOT lithium-ion, they're non-rechargeable and are usually Lithium/Manganese Dioxide [1] (lithium metal). I believe they're fine to have in checked luggage if contained inside some equipment (like the airtag). [2] Look for PI 970 If transported by themselves, they're cargo aircraft only.

For those interested in the various aircraft systems for PA (public address) and aircraft status system for aircrew, I found this interesting training doc PDF online [1] for the A320/321. I have been looking at section "03-010 CABIN INTERCOMMUNICATION DATA SYSTEM"

It does not mention the "medical intercom jacks" in overhead bins that are mentioned at the end of the article

This was a a nice read, really detailed. I especially liked that he had the MCU talk directly to the camera with S.BUS (a weird uart with 2 stop bits for the control interface) despite the issues he encountered, instead of going the slightly easier but less elegant route of having a separate computer in the loop to do the HID <> S.Bus translation.

I love the idea he links at the end to implement TOTP using an arduino/esp8266 [1] inside the safe, to derive the opening PIN.

I've really been enjoying mine with Home Assistant buttons to trigger lights and show sensor values, as well as a really neat way to apply tags while looking at images in digikam (through one of the windows streamdeck plugins that allows complex key sends including modifiers.

I also like it as a way to quickly open saved PDF datasheets on my system for the ones I use all the time.

I use a streamdeck with VS Code [1] and it's been really nice. You can map any actions that you could run with Ctrl+Shift+P (the command bar) and also have it send commands to the vscode terminal. Works great for me, including on remote servers connected through vscode. On mine I have a key for reload window, start debugging/compile, and all the actions for the debugger (step through, pause, next etc).

On desktop as well (chrome) making me go back immediately.

Amazing scans, the packaging of components internally is amazing.

Interesting how they switched from prox-based in-ear detection to capacitive skin contact sensor in the latest airpods.

This is the actual manufacturer of the tube from the article! A modern nixie tube manufacture, they have had to (re)learn the processes and tooling again, from old books, and acquiring old tools like that awesome glass lathe. Their youtube channel is great to watch, they explain a lot of their steps.

Apparently the camera in last year's M1 macbook was already a huge upgrade compared to previous ones, and the new macbook pros have a higher quality 1080p sensor, and both leverage some of the special IP blocks on the chip to make the image even better, so it should almost certainly do better than the C920 (especially around audio capture as well, if you use that)

> USB-C only guarantee 60W charging.

The original PD 1.0 spec went up to 100W (20V/5A). Newest PD spec (3.1) can do up to 240W. And I think apple's magsafe cable terminates in a male usb type C, so it still uses PD internally at least.

A fun dive into windows history and backwards compatibility.

Apparently per their Privacy Policy [1] you can text them back with "DELETE DATA MM/DD/YYYY" (date of birth) and they will delete everything. It seemed to work for me, the reply told me "my information has been deleted".

Anecdotally, it also was useless for finding a vaccine slot.
