Just think of all the countries and companies that grab this data, group by email address, then start to identify preferences of people around the world. Its not just for identity theft. The possibilities are endless! And horrifying.

I'm not an HVAC technician so I wouldn't know exactly, but I think there's two things to consider: static pressure and duty cycle. Static pressure is the fan working hard to spin which causes wear on bearings. Duty cycle is how long the machine runs. If your duty cycle is too low then the machine is turning on and off quickly which is bad.

You could look at the size of the unit and there's some rules of thumb that translate size, climate, and square footage of just the areas you leave the vent open and there are online calculators you can use.

I think the only way to know for sure is to measure the pressure drop across the intake and outflow and see what the fan motor is rated for.

Depends on the unit and whether it was over sized or under sized for the space, but restricting 60℅ air flow is a lot.

Another thing to consider is that if you later want to heat up the entire house, the unit has to work harder. Sometimes it can be more efficient to just keep the house close to your target temp.

 

Announcement by the creator: https://forum.syncthing.net/t/discontinuing-syncthing-android/23002

Unfortunately I don’t have good news on the state of the android app: I am retiring it. The last release on Github and F-Droid will happen with the December 2024 Syncthing version.

Reason is a combination of Google making Play publishing something between hard and impossible and no active maintenance. The app saw no significant development for a long time and without Play releases I do no longer see enough benefit and/or have enough motivation to keep up the ongoing maintenance an app requires even without doing much, if any, changes.

Thanks a lot to everyone who ever contributed to this app!

It's possible, but it costs money to design the hardware so it's accessible, it has to use a connector which has to be robust against vibrations (is m.2 robust?), then there needs to be a standardized protocol to communicate with the card. Does the car computer need to know how to authenticate against the cell network or does the card? Is it industry standardized or specific to the manufacturer? All kinds of things need to be designed and car manufacturers have no reason to invest in they.

The problem is the cell modem in the car, which is hard to replace. Cars last a lot longer than phones do. When whatever network that the car uses shuts down, then you can't remote start your car. That's a marginal cost that the car company has to pay for.

CDs have an advantage over USB drives in that they can't actually secretly be USB HID devices like a fake keyboard or mouse that runs a bunch of commands when it plugs in. It's only a storage device.

A super secure environment might then lock down all USB devices to ones known by them and then epoxy all ports and devices.

Great if only my family would even believe this as opposed to just saying something about FEMA using DEW and HAARP and space lasers to actually create hurricanes to be able to extract lithium or something.

ICANN specifically set aside all two character TLDs to be for country specific codes. There's only a few cases where they kept ex countries TLDs around and phased them out over several years. It would be an entirely new precedent if they did keep it. So I wouldn't depend on it

I have my doubts that a company would be able to just abandon a live and operational nuclear power plant. I'm no nuclear or power engineer, but I am familiar with data center power consumption. There are companies in the region that would absolutely build more data centers, but are power constrained from the utility companies in the area, that are not just for AI, but for general compute. Even then, it's low carbon production energy. If you have a ton of excess power, just start forcing high carbon production facilities in the area to close and now you've greened the grid.

While I'm not a fan of the loan nor the massive waste of power most LLMs are, I actually think that's its a good thing because if Microsoft can break through some of the excessive red tape on nuclear plants then they'll bring this online and hopefully prove that nuclear power can be safe and a good source of large amounts of power, when the huge demand for AI dies down, then maybe they'll keep the plant around and provide power to the grid.

On Android, you can specify which applications you want included or excluded. Or you can specify that you only route your home LAN IP ranges through wireguard. Both of those would accomplish your goal.

Kind of but it's not fair to put it all on the manager. Multiple people decided to hire the person. Somebody else approved that code review. People approved the technical design. Why didn't the tech lead raise concerns with the manager about someone's under-performance, etc. it's unfair to just put all blame on the manager.

The idea of extreme ownership is about not saying "not my problem I won't do anything" or blaming your reports. It's about saying I can and should do anything and everything in my ability to fix problems.

 

I'm excited to see this as I'm pretty much only use Z-Wave. Also interesting is they are developing their own dongle

 

Windows and macOS have similar clients (Hass.Agent for Windows and Home Assistant for macOS).

I've found these kinds of clients useful because I can remotely wake-up or sleep computers, track how long they are turned on for, and automatically pause my lights and music when my webcam turns on.

 

I thought the model of 3D printing models of the chips to be a really cool way of visualizing how these chips work.

From the YouTube summary

How does your phone track its position in space? MEMS devices! Phones use small micro mechanical chips called MEMS, to monitor accelerations and rotations. These are fabricated using semiconductor technology, but are tiny little moving mechanisms.

Today we're decapping a six axis IMU (MPU-6050, on a GY-521 breakout board, containing three accelerometers and three gyroscopes), looking at it under the SEM, printing up some models, doing some high speed video recording, and talking about how these little MEMS devices work.

CAD/STL models (fair warning, it's a very challenging print!): https://www.printables.com/model/413667-mems-model-six-axis-imu-device
