I'd definitely be interested in a project like that, but I think customizing a PCB layout and sending it off for manufacturing would be too much for many people that would otherwise be interested in it. I think a project like that would gain more traction if it focused on designing high quality boards for a few popular laptop models (MacBooks or ThinkPads IMO) and making those available via on demand manufacturing and/or crowdsourcing a bulk run.

My friend has the opposite problem. The ISP's map claims to offer fiber service on his whole block, and if you type in your address they'll even offer service at that specific address. The problem is his block is at least 80% multi-tenant dwellings, and they'll only do new installs if everyone in the building subscribes. They don't just want permission from the landlord to wire the whole building at once to save time if future tenants subscribe, they're just not gonna do it unless everyone pays. In my friend's case, they didn't even tell him this ahead of time, despite explicitly saying he was in an apartment on the form he filled out when he attempted to sign up. They just "helpfully" change it to a request for DSL service. This was explained to my friend by the technician that showed up with DSL hardware only capable of a faction of the speed he was currently getting on coax. Obviously, he refused service. Then he got to fight AT&T for a few months over bills for DSL services he never requested, and rental for hardware he never accepted.

I've actually bought/planned to buy a few things that I was introduced to via YouTube sponsorships, but it's never been any of the generic YouTube sponsor merchandise. It's always something highly relevant to the topic of the channel, or even the specific video. Usually some sort of specialty tool.

It's no longer functional, but in the past if you appended the parameter t=wadsworth to a YouTube URL it would skip the first 30% of a video.

There's a torrent going around the usual places that has every [as] bump from the launch of the network to whenever they last updated the archive (a few months ago in my case.)

Yeah, I hear people repeat that a lot, but it doesn't entirely align with my experience. A lot of the grocery stores I shop at (mostly Kroger and other national chains,) have a cooler right up front with the most popular dairy/refrigerated items for the people that are just there to pick those up.

A bunch of stuff you will absolutely not care about. Unreleased music, rough cuts, behind the scenes footage, promo materials, etc. . .

Nothing about the content itself that would be interesting to the average HN reader, but I think this is the first time a celebrity has officially released a massive data dump like this.

IIRC, Emby has also had some GPL compliance issues. Jellyfin is a fork with of Emby with all the crap removed.

They're storing information about the app's current state, as well as tracking/analytic info. If you don't care about linking to an identical view and just want to link to a specific location, you can trim the URL down to just the coordinates like this: https://www.google.com/maps/place/@55.9285659,-4.7106362,17z...

What devices are you using? I upload to imgur from my phone all the time. Just do it from a browser in desktop mode, you don't even have to login.

Don't forget about birth defects. I went to school with a kid that was born without pinkies, but otherwise completely normal looking hands. You could still tell something was off when you looked at his hands, but it usually took a few seconds for it to register with most people.

Look under the heatsink. You're probably going to find 6x 2GB chips in parallel. The individual chips have a power of 2 capacity.

Now that you bring it up, I can't recall ever (knowingly) using a piece of Korean software that wasn't a game or baked into a phone's firmware. Does seem kind of odd considering how much Korean hardware there is in my life.

My family had one about the same size as well, and it was setup in the basement. When my parents sold the house the contract stated that the TV in the basement would not be removed and it was the buyers problem now.

Same way as vanity onion domains: brute force. Anything else would be a security flaw. If you're asking how to actually get one yourself, just search for "bitcoin vanity address" on github. There are plenty of projects to choose from.

A modded iPod classic is hard to beat. Replace the HDD with a CF card (many of the SD and SATA adapter boards don't have support the drive's power saving features) and stick the biggest battery you can get in there. I've seen people get 100+ hours of playback from a modded iPod.

I honestly can't remember if it showed up in the strobe or not, this was a few years ago. This procedure wouldn't be listed in the regular manual. It involves opening it up to adjust an internal potentiometer, and can't be reliably done without a frequency counter (I guess you could do it through trial and error, but it would take forever having to reassemble it and play a test disc after every adjustment,) so it is only in the service manual. You should be able to find a scan pretty easily though. Can't remember what frequency you need to hit, but it's low. If you don't have a proper frequency counter an Arduino will work just fine.

A single 18650 can do much more than 30W. My Emisar D4v2 can pull ~17A from a single 18650 on turbo mode, and it's not much bigger than the battery itself. I carry it on my belt everyday. It starts to get a little uncomfortable to hold and eventually triggers the thermal protection after about a minute of continuous turbo use, but that's more than enough for a quick prank. It runs an open source firmware too, so I could theoretically swap in some IR LEDs and program it with the appropriate modulation.
