First, the police can often get a warrant very quickly (like, an hour) in am emergency. Second, there are some exceptions in the case of an immediate threat of harm or destruction of evidence. But if you have time to get and fly the drone,

It's really a fascinating question. Is it warrant-requiring surveillance if they capture a photo once per year as part of a survey? What if they park a drone over your house 24x7? Technologies that can see through your walls like therm

It's about 3.5-4 smoke detectors worth. This source contains about 3.5 ucuries; a typical smoke detector contains 1 ucurie or less. I think the biggest danger is that most people know not to dig around in the inside of a smoke detector

It's mostly about avoiding the latency penalty. There's only so much ILP you can extract from the instruction stream before you get stuck waiting for a dependency. If you started executing that dependency speculatively, it will co

Right. The watch has LTE and does its thing independently. It does have kid features like schooltime. It's not priced cheap for kids - cheapest new is almost $500. (Hence giving our kid a two or three year old, used one. :-)

You can attach a kid watch to your iphone plan. They get their own number and are part of your family management. It works really well. At least one parent must have an iphone, though. There is no watch specifically for kids, we just gave o

Doesn't even have to be about tracking - we got a limited watch for our kid when she was 9 or 10 so she could call and text us if anything came up, and used that as the basis for letting her do her own thing even more. Was fantastic. I

I don't think this is a great place to re-litigate this, but I believe DFJ's investigation found a pattern of affairs, but not harassment. https://www.usatoday.com/story/tech/2017/11/18/ste

FV was our seed-round VC, and I snagged a set of photos if anyone wants more -- though they're not nearly as good as Steve's photos in the link above! https://photos.app.goo.gl/uPBt1z3UnLxoSx9P7 But I really liked

Sure. I'm not trying to say they're the same thing. But the vast majority of climbers have a _conscious_ approach to risk. Some risks are worth taking. Some aren't. The key is that you have to be aware of them and be proactiv

I'm afraid that means you don't understand climbing very well. For almost all climbers, climbing and mountaineering entails a lot of managing risk. It's a constant partner in anything you do, and one thing you learn from clim

The immoral part is how badly many elementary through high schools teach math. As a math-adjacent (CS) professor, it was painful to watch my daughter's math experience at her first elementary school. Part of the reason she's not t

To dive slightly into that: You don't necessarily want to sacrifice space for a read cache disk: having more space can reduce writes as you do less replacement. But where you want endurance is for a ZIL SLOG (the write cache, effective

I use mine (electric) to blow leaves from the street and sidewalk back onto my grass so that I can mulch them with the lawn mower. I also use it to blow debris back onto the grass-free perennials area around my tree to get free mulch. I&#x2

You're placing the blame on the wrong thing - The embodied energy of producing most of the things we consume is much higher than the energy of shipping. Shipping on a massive container ship is really impressively efficient. (Shipping b

WWVB is great if you can get the signal -- I have two of those clocks in different rooms, and only one of them synchronizes.

A cheap watch or clock will use an off-the-shelf crystal oscillator, where you'll be lucky if it's accurate to 20 seconds in a month. A temperature compensated crystal oscillator (TCXO) can do better than one second per month, but

Well, you can probably send out one bit a time by updating your ACLs on a clock (with which your clients are also roughly synchronized) and distinguishing between 403 and 404. take an awful lot of time to get that data out, though.

Weather has been good today in the region - low heating and cooling load, and it's a weekend; demand is comfortably low (currently about 72.5GW with a forecasted peak of 77, vs an actual peak of 85GW yesterday). Should keep things pret

Because cities are awesome: density gives you choice. In a city, if I have a gifted child, I almost certainly have several options for what school to send them to, many probably within walking distance. In a sparse suburb, I have one, unles

That gets broken by constructs like sum(all of column 5) when new rows or columns are added. (It's very similar to the problem of locking in databases)
