You're probably missing some library or other. I know I had to install something in debian unstable, but I don't remember what it was. U2F definitely works on Linux, though.

On Android, the Google Authenticator app handles U2F via NFC. Sadly not possible on iOS.

I'm not that directly involved in Thrill, so I can't really speak with authority. There aren't any concrete plans on fault tolerance but it would certainly be an interesting topic to work on, partially because the existing

These high-level features don't have any performance impact: Reference counting is used on very large objects or for things that aren't touched a lot, so there is no measurable impact on performance or memory use. Lambdas don&#x27

Did you try the discovery features? Many people find them to be among the most valuable features of Spotify. I quite like the discover weekly playlist that is auto-generated every Monday, and the daily mixes are quite good as well. Or see i

No, sadly scientific CS conferences are only rarely recorded.

I think with Thrill, there are two different skill levels to be distinguished: - Using it to implement things should be fairly easy and doesn't require advanced knowledge of C++. Basically you have to plug lambdas that do the processin

DIAs are quite heavily inspired by RDDs. A lot of the performance increases come from the C++ compiler's ability to fuse local operations etc. Thrill doesn't implement any fault tolerance at the moment, it's closer to prototy

Thrill and STXXL are both delevoped in the same group at KIT (I work there, too, but I'm not directly involved). Thrill also reuses some parts of STXXL, and does so completely transparently to the user - if memory doesn't suffice,

A Netflix subscription is around 30 cents per day. Not to mention that 15 minutes is a very generous estimate, the median is probably closer to 3-5 minutes. Given that the article isn't written for me , that sounds rather fair for acc

Well yeah it's clearly still NP-complete. But the TSP (or variant thereof) isn't related to the routing engine at all, as the routing engine only defines the edge weights. They're fairly orthogonal problems. Logistics softwar

Nah, it's just that it took work to integrate turn restrictions, and that that results in a bit of a slowdown. It's easier to do research on a more limited version of the problem (shortest path in a road graph with a suitably chos

The portion you take issue with is a quote from the same article that you're referring to, and clearly marked as such. I'm sorry that your "comprehension failure" insult backfired. By the way, the map on the bottom right

This is not front running (which is illegal). It's trying to be faster than people who trade manually based on the same info. The term front running has a pretty clear definition, it's roughly when a broker trades on your orders b

It's not TSP. In TSP, you have a graph and want to visit every node exactly once . Here you have a (road) graph and want to visit some set of nodes (the delivery addresses) at least once (it's okay to drive past a house where

Since you need turn restrictions if you want to compute routes that users can actually follow, adding different costs for different kinds of turns (left, right, U-turn) is easy. See my other comment in this thread on the challenges associ

Incorporating turn costs into route planning is actually not that easy! For one it increases the amount of data you need (street layout, type of intersection, etc) and a lookup to add the appropriate penalty. But more importantly, it doesn&

Turning right on a red light is only permitted after establishing that it is safe to do so. Obviously you can't just assume that it'll be fine to go. The difference between your country and the US is the default value: do you have

Yep, but it's still better than not using a second factor at all. It all heavily depends on your threat model. I don't think Yubikeys scale to the general population, carrying around something on your keyring is a hard sell for ma

That only works without an ad blocker. Otherwise it redirects to the paywalled desktop version. This is what plenty of people have been complaining about recently.
