I ran through the Michel Thomas 8 hour audio course, then 3 semesters of evening class at my university (run by the language dept). That was about 60 hours of class time, 2 hours a week. By the end I would have been comfortable going for B1

Duolinguo is a poor substitute for human interaction. It's a good tool to support other methods, but it encourages pattern matching rather than actual memorisation and there simply isn't enough variety in the examples to help you

In my experience it's rarely a problem with the material itself. Motivated or engaged kids will quickly outpace "kids" material anyway, and will move onto conventional resources. Right now cheap resources available to educato

What you're describe is sort of the first and last steps. As I understand it, the solution involved comparing the pattern of sand in the pack world (that they figured out from the picture) against all possible seeds. Doing all the init

Out of curiosity, what throughput do you have that would require GPU labelling? The most resource heavy bit is text rendering I guess, but that could be cached per class-name and reduced to a memcopy. Otherwise drawing rectangles is pretty

I would guess the library uses OpenCV primitives to do things like figure out the size of the label before drawing the background fill underneath. That's normally where the complexity comes in for drawing labels. I'm not sure if y

We have the chewy ones from Bassetts. The amount of Vitamin D is low though, only 5ug - typically the standalone supplements are at least 15ug. It should be safe to take a multivitamin plus a separate D tablet. The NHS limit is 100ug I thin

This is also an issue for planes landing at the South Pole, where the plateau can have a pressure altitude of up to 12500ft. If you arrive in a Hercules (as opposed to a DC3/Basler which is unpressurised) they have to vent the cabin ju

There is a very simple way to tell if an ML script has failed: the GPU fans turn off. No joke. Even with a water cooled machine, I know something has gone wrong if I come back in an hour and the rig is silent.

I don't want to assume anything about the parent background. When I see things like "1000 applicants" I assume these are likely to be either generic roles, or well publicised roles. Even then, most of those 1000 people are un

There's low power inference from Intel (Movidius) and Google (Coral Edge TPU). Nvidia doesn't really have anything below the Jetson Nano. I think there are a smattering of other low power cores out there (also dedicated chips in p

Is the situation better with Mali? This seems something that might actually improve with Nvidia. I was under the impression that ARM GPUs are currently heavily locked down anyway (in terms of open source drivers). Nvidia would presumably st

Worth mentioning that youtubedl works with a lot of sites, not just YouTube. Most of those PRs are for other supported websites or requesting support for new sites.

But surely strings are valid? Unless you want some kind of static type checking/linting for eg an ipv4 vs ipv6 key? Strings are very portable as well (POD). Plenty of real world applications use static hostnames and rely on DCHP to ass

Qt creator is really not bad for non Qt projects. It can be set up with cmake quite easily. It's also FOSS. Maybe I'm used to it from working with Qt a lot, but I prefer it to VS Code for debugging (GUI interface to define configs

These are called perceptually uniform colormaps and are also useful for grayscale printing, as the scale will still be valid. This is now the default in Matplotlib (eg viridis, magma, etc) https://jakevdp.github.io/blog&#x2F

Sure! The Zero is great as a cheap DAQ, I use them all the time. But the SBC that it's being compared to is much more full featured and I don't think you can say it's worse or even comparable.

The Pi Zero is single core at 1GHz so it's not a totally fair comparison. There are plenty of times I wish I had more cores, even if they were half the speed. Compiling anything on the zero is incredibly slow. It also has slower DDR2 R

You could also call that centred to clear up confusion, or mean-subtracted to be more specific. I think if you're specifically dealing with statistical quantities it should be obvious, e.g. standardised if you also scale to unit varian

This is also how ATIS works - these are condition reports for airports that are broadcast on a loop. They tell pilots the active runway (if a small airport), surface weather, etc and any special information. They're often fully synthes

Yep, more that actually being able to turn interrupts off is a barrier to doing real time work on desktop OS's, for example. Even if you can disable them globally (I think on the Pi you can with some low level C), but stuff goes wonky

I feel like this is more an issue with cheap construction (and what people will pay for) than anything else. I've stayed in people's apartments in the UK where the light fittings rattle if upstairs is running a wash. These flats a
