Sorry to be such a bore but when scanning humans the images should only be good enough to make a good diagnosis. If they are better than needed, the wise thing to do is lower the radiation exposure.

For plaque buildup they normally do a quick low resolution scan (to calculate an “agatson score”). I did not know by heart, but according to webmd.com it’s equivalent to 1 year background radiation. Pretty and high resolution images like th

On the face of it, it looks like a potential source for security issues when untrusted input is logged.

I know they don’t subsidize standard development. But there is still cost for running an organization to manage and coordinate (and maybe translate) what is being standardized over hundreds of topics. Of the 40 million in total income, sell

It is great when standards become free, but then we need to agree how else to fund the standardization process. Taxpayer money?

It is too early to assume that. It just fails to optimize that specific piece of library code, but when the author implements it himself LLVM does choose cmov instructions. It still can find the optimization but either something is preventi

We can all read it how we like it: “Climate researchers ignore undesired effects”, or “contrarian outsider is cherry-picking results”. Intention or not, this serves only as flamebait and it will get us nowhere.

Dunno, I think I’d rather wait in blissful silence.

Excellent post I agree, but isn’t it more about how they can’t optimize? Compilers can seem magic how they optimize integer math but this is a great explanation why not to rely on the compiler if you want fast floating point code.

Comically, the author used a stock image to explain how recessive genes work, where the unaffected individual is blue, and the affected is red. It serves more to confuse than explain.

RSA cryptography is is based on the assumption that factoring numbers is a hard problem. Isn’t kind of nice to know that there curious people trying their best to see how fast you can actually get?

Amazon prime you mean? Came her to complain about that. In the prime app, there is a button that disconnects your device from the account, but it just logs you out. You need to go to the website to manage your subscription, and after a few

Well, in the relation between user and browser vendor it is quite a reasonable default. I can always change my mind if I want to give up my privacy.

There can be very specific exceptions. In C# Winforms code I wrote, I have data loading code which I made async, called from UI code that was not. You need a running messageloop which was provided by a modal progress bar. Users could cancel

It is only prior art if it is made public. If you invent something and keep it secret someone else can still patent it.

OK, from the comments I read so far I realize that I may have been lucky with an older laptop. And I did not mention that I also turned off wake timers, realized that now. If this does not work on modern hardware that’s a real bummer.

I absolutely agree that microsoft could and should make this work better. But the pragmatic workaround is the setting to force hibernation when you close the lid. You can resume from SSD in 10 seconds. No middle of the night wakeups. Much i

The mouse was also the issue for me but I switched to a trackball. All the work is done by my thumb, no need to move your arm around.

For me, that is a selling point! Widescreen is nice for movies, but when coding or browsing more lines is way more useful.

I imagine that you have regions of normal RAM reserved for Peripheral IO, and that the peripheral directly copies it’s data to or from that region using DMA. For the CPU and the driver developer, this means there is no special handling requ

by superjan 5y ago
Thanks! I could still read this two ways however: one where the memory is on the peripheral, and one where the memory is main memory, where the peripheral is copying to/from using DMA. Which one is it?

by superjan 5y ago
So one thing I still wonder about is why PCIe peripherals often present themselves as a region of memory to the main processor. If the chipset/CPU is buffering writes for fast transmission, does it guess when you are done writing? Is a

If you have electricity, there are also electric incinerator toilets. For a summerhouse that can be a environmentally friendly and hygienic solution. They can handle urine but I prefer to pee outside.
