Questionable behavior from YC companies is nothing new.

Apple Card already offers credit limits high enough for it

That’s exactly what this is. 9 months to production is completely impossible anyway. 9 months from design to early samples is probably impossible given than TSMC takes 3 months aft…

The Buddha lived before writing in India. We have plenty of other stories that were passed by oral tradition before they were written down.

The time from tapeout to first samples is 3-4 months even for the biggest customers of TSMC. Shorter for a metal only change.

In the chip design world, 2:1 for design verification to design is on the low end of normal. Some organizations have gone as low as 1:1 but that is considered an emergency that mus…

The joke is that AI companies pretend to care about doing legal things.

My solution is that I no longer contribute to the public internet in any meaningful way. No more open source projects. No more contributions to free software. Bug reports only when…

Methodology doesn't support the conclusion. Try using images that it wasn't trained on.

I don't know of any CPU that speculates both sides of a branch. I work on a CPU design team. Modern CPUs speculate hundreds of instructions ahead, and with just a dozen branches yo…

Software table walk performance is bad on modern out of order processors because it has to finish every older instruction in flight and redirect the front end to the exception vect…

In AArch64, `BR LR` and `RET` do not perform the same logic when FEAT_BTI (Branch Target Identification) is present.

As a professional EE, I know that ARM Cortex-M4 is not a chip. It's an embedded processor that is put into an SOC (which is a chip), such as the STM32-family from ST.

More cooks can't make one meal better but more cooks can make dozens of different meals and you can choose the best result.

John Carmack had some things to say about it: https://www.forbes.com/sites/paultassi/2022/12/17/john-carma... EDIT: direct link https://www.facebook.com/permalink.php?story_fbid=pf…

How is your wifi network? Have you tried changing the display resolution on the Mac while you're connected to the Vision Pro? The virtual display doesn't look as good as the laptop…

You can read the theory of operation for generating negative voltage in this application note from Analog Devices: https://www.analog.com/en/resources/design-notes/generating-...

Compare phones to game consoles.

Can you make a compelling argument? Just saying it’s wrong is not an argument. If employers don’t like it then they should pay by the hour for 24 hours a day, 7 days a week.

Having multiple threads does not mean that they are all doing equally useful work. Single threaded performance is absolutely critical for a desktop machine. Even in multithreaded d…

100% of the CPU design team at Samsung in Austin was laid off in 2019. That's why none of the authors in this 2020 paper have a Samsung email address.
