I work at a university that is fully invested in Google Apps.

We did have unlimited storage, however last week they announced that's soon to change:

A quota will soon be introduced on the amount of data that staff and students at the University can store in their Google account. This is part of a larger piece of work being carried out by the Google Workspace team in IT Services, to review the overall amount of storage being used by the University.

Makes me wonder if the timing is somehow related.

There are still inconsistencies between NHS dentists, visual assessment of cavities and what justifies treatment is inherently subjective.

My first dentist retired after I'd had no fillings to date, their replacement on first appointment said I required two fillings and it continued in a similar manner.

Later on I had moved city, but was still travelling back for dental appointments. The second dentist said I needed another filling doing, but I ended up moving to a new NHS dentist in my new city. They disagreed about the filling, saying you can't fill teeth if it would go below the gum line. Pulled the tooth instead.

Even with NHS appointments, you can go 'private' a-la-carte if you can be convinced to have white fillings or similar extras and pay slightly more.

I have two yubikeys too, but I definitely found services which didn't allow me to register more than one when I first set them up (a couple of years ago now).

My favourite example of this in English is adjective order.

Native speakers learn that it should be "big red bus" rather than "red big bus", however most couldn't list the ~7 adjective types and order they should be used in, yet will know straight away when they're wrong.

AWS BugBust 5 years ago

The $769 is referring to the estimated money saved by fixing bugs, rather than the trade in value of the points.

For information on how points are awarded, see the Official Rules. Actual savings may vary.

Section 5 of the official rules document states approximate retail value of the prizes as; reInvent:$4000, Resin Trophy:$60, Hooded Sweatshirt:$27, tshirt:$12

It's not that GPUs don't support fp64, it's that for domestic gamer GPUs fp64 arithmetic is normally ~1:32 performance of fp32 arithmetic.

e.g. 1080gtx

    FP16 (half) performance
    138.6 GFLOPS (1:64)
    FP32 (float) performance
    8.873 TFLOPS
    FP64 (double) performance
    277.3 GFLOPS (1:32)

e.g. 3090rtx
    FP16 (half) performance
    35.58 TFLOPS (1:1)
    FP32 (float) performance
    35.58 TFLOPS
    FP64 (double) performance
    556.0 GFLOPS (1:64)

Only generally 'tesla' class cards targeted at super computers have a 1:2 ratio (e.g. v100, A100, Titan V). Note, I believe Titan V is the only Titan series GPU with good double performance, as the Volta architecture was never available to Geforce GPUs.

The suggestion we sell to other countries to make more money is not right because we make no profit everywhere.That's the approach we took and we agreed on that. That’s the agreement we have with Oxford University. It's actually even written in a contract we have with Oxford University: that we will be at no profit. We have slightly different prices from one geographic to the other because the cost of goods may be different. We have a supply chain in Brazil, we have another one in Latin America, another one in South Asia. We have one in Japan. Of course, you know, local costs are different. So you've got slight variations, but more or less, it's about three to four dollars, more or less everywhere.

This was an interview with the AZ CEO when the EU delays first kicked off: https://www.repubblica.it/cronaca/2021/01/26/news/interview_...

The core difference for the EU contract was that the EU wouldn't accept any/as-much liability for any harm caused by the vaccine (compared with UK/USA). Not sure the source of this claim.

Vice posted a new video (about American Apparel) to their YouTube today, was tagged with Quibi at the start and end.

Historically there was an emulator mode, where you could build your CUDA code to run on CPU. However, it was removed a few years ago. I never used it, so can't really give you more details beyond that.

The video here talks about the difference between the two approaches. There's a comparison at 2:50.

"I think the computers are winning, because in the upper right you can kind of see that back wall, there's a little strip of green. It's kind of blurred out a little bit too much with the human version, but the neural network has picked up on that and kept the vertical stripes there."

We've come across this problem. The major testing frameworks seem to rely heavily on macros for tests. In particular, we were struggling to handle tests of thrown exceptions, as we couldn't trivially capture the result in a variable and place that inside the macro instead. The most versatile solution we found was to use a function pointer, so that the templating wasn't required when the function was called.

Recent versions of CMake have also been growing the support for CUDA. There's still a number of edge cases (e.g. passing arguments to the device linker) that have open tickets on their bugtracker, but there's more than enough stable functionality now for CUDA projects and generally a number of relevant improvements with each new release.

We started using it about 6 months ago for a cross platform CUDA project, and have found it to be a big improvement over how we previously managed similar CUDA projects (e.g. manually). I'm especially a fan of it's ability to download external CMake project dependencies. As others have mentioned, some of the documentation is a little unclear for particular edge cases though so it takes some familiarisation.

Fortnite has been criticised for it's store. Item's are only available for a limited time (24h?), with no guarantee of when they will become available again. This creates the 'Fear of Missing Out' incentive for people to spend.

I've not played it first hand though.

On the otherhand, this article is discussing someone addicted to the gambling element of TF2's crates (aka loot boxes).

When developers generate Steam keys, it allows them to sell their 'game on Steam' elsewhere (their own website, HumbleBundle etc).

This means Steam doesn't take a cut of the sale price. But the developers still get the benefits of Steam community, Steamworks drm, and potentially having a unified update/distribution channel.

Similarly, some gamers prefer to have games 'on Steam' rather than DRM free so that they have a single unified game library.

Those shared accounts might be accounts hacked with known/breached passwords.

I previously had my mostly empty UPlay account hijacked by someone with a Kazakhstan IP. As I recall they renamed the account and added new friends and had been playing a game I'd received free, but didn't change the password. Mostly just spurred me to switch everything feasible to 2FA.

The android app "Google Opinions Rewards" occasionally asks me to rate a video i've recently watched, then follows it with a binary choice of recommendation, which I subsequently have to rate the quality of the recommendation.

I'd assume that data is being used for training somewhere.
