Advertising is a marketplace... If a bunch of ad-buyers quit the marketplace, then prices will go down, and the ones who didn't quit will get a better return on their investment.

There are some with redundant data feeds. It means any one LED can die, and the rest still work correctly. If two LED's next to one another die, then the whole strip still fails, but obviously the chances of that are far lower. When lo

Time to get a fix is mostly what clever techniques the receiver uses. There are various papers demonstrating getting a fix that is probably correct with just a few milliseconds of signal and then lots of processing. You also have to cut

And before long, someone will make a 'deleted comment finder', which highlights only deleted comments. Could be especially handy for journalists and law enforcers.

There is no requirement to automate GDPR requests. However all organisations must be able to handle GDPR requests via any communication channel. Eg. They need to treat a data deletion request sent via twitter DM as a valid request if they

But there are plenty of other unclear road signs that apply to everyone. Eg. "No left turn on school days, except permit holders, except for access". Whose school days? What kind of permit? Where do I have to be going for it to

It's £12.50 per vehicle per day. I doubt that public health costs of a single vehicle used for a single day add up to anywhere near that much - perhaps only 1% or less of that.

I support measures to phase out polluting cars, but as a driver I find the cognitive load of figuring out where I can drive and which fees are payable is getting rather high. "Drivers of cars made before 2006 must pre-pay a £12.50 fee

One day, compute requirements will be part of a companies eco-statement. Eg. Amazon will be forced to say 'For every item purchased from Amazon, 370 grams of CO2 are emitted by our servers and other business operations :-P'

No. From the typical 2's compliment number encoding used on all modern computers, it is not a simple rotation. Think about the encoding of minus 1 for an example that differs...

Recurring payments have massive lock-in - typically there is no way to switch payment providers without requiring the user re-enter their payment details. You'll typically lose ~half the user's each time you do that...

Less than half the population has decent geolocation by IP. Most people the IP address will only identify the country or even nothing at all. Not much use if you want to search bakery's.

A bit reason for using separate subdomains originally is because there are security benefits. If there is an XSS attack that leaks cookies from Google Keep, you would prefer that not get your cookie for Google Maps. As browser security mode

Nobody in the developed world will allow a nuclear reactor to be built anywhere near their house... So, however safe these are, they'll still be relegated to 100+ miles from any big city. So the transmission costs will be similar to

Purifying air seems like a tricky challenge. How much energy would it take to fractionally distill air? Ie. Liquify all the air in your house, boil off just the gasses you want, and pipe that back? Then you could choose for example to have

I'm kinda surprised efforts like this aren't more heavily sponsored by other countries. Like if you were Russia or Iran right now, paying a bit of money to keep wikileaks' servers running would seem like money well invested.

I think the real fix is to set all registers to a canary value at the start of int main(), and then when exiting check the canary value is still there. If anything has messed with any registers without permission, you crash and collect as m

Having a 2nd level cache that only has a 2% cache hit rate doesn't really seem worth it... Isn't it better to just get rid of that layer all together and have a simpler system?

One thing that's notable is that an insulator for high temperatures (eg. Soft fire brick) is very different from an insulator for low temperatures (eg. Your freezer). High temperature stuff might get 0.3 W/mK. Low temperature stuf

The audit documents make clear they are point-in-time. I'm sure if they could do an audit for a full year/quarter, they would. But they didn't, so they can't.

It's really noticeable that work on site at spacex really ramps up before an Elon visit, and then pretty much stops when he leaves again. If he doesn't visit for a few weeks, nothing gets done.
