Deblock, an app that lets users manage fiat and digital assets in one place by linking a bank account with a self-owned crypto wallet, raised a €30M Series A (Tamara Djurickovic/Tech.eu)

Unfortunately, it look like Senate Democrats might have less latitude to block ICE funding than we’d hoped:

I say make those calls anyway. I want all of them desperate to stop ICE, up sleepless at night trying to figure out what they can do even if there’s nothing they can do.
TIL you can use `ffprobe` to get the GPS location of an iPhone video like so:
```
ffprobe -i input.mov -print_format json -show_format -v quiet
```
The resulting JSON output contains a key `com.apple.quicktime.location.ISO6709` with the concatenated latitude, longitude, altitude, like so:` 46.6240 012.0345 1866.934/`
There's also a `com.apple.quicktime.location.accuracy.horizontal` key with the lat/lon precision in meters...
(This is great news for the m…
Can anybody please calculate for me the time #dilation numbers related to how much faster someone at the equator is moving compared to someone at, say, either of the poles? Or anywhere in between, really. Ideally, a simple formula that correlates degrees of latitude with speed of revolution would be great. I’m at 40°30’36”N, and 4960ft elevation. I presume elevation also factors into it.

The DST switch has two advantages: moving an hour of summer daylight we'd normally sleep through into our evenings, and reducing the variation in the time of sunrise (avoid dark mornings).
A 1-hour adjustment makes quite a big difference in middle latitudes. Too far south & the natural difference is too small; to far north it's too big for 1 hr to matter. South of 40°N and north of 60°N the argument is weaker. See the graph: at 40° the difference in sunrise time is 2h52, at…
