Ditto. Instagram and tik tok are the biggest offenders in my mind. I will never ever install either.

What would you propose instead of forks/signals/process management? There needs to be some way of managing different tasks whether that's threads or otherwise

I'm really sad I missed the boat on Vanced by one day. I'd heard about it for a long time and randomly decided to finally start using it only to find all the download links had been removed the day before. Youtube ads have become

It's not really about the the hassle of changing clocks, or even really about the shift itself, though it is annoying and completely arbitrary. While the time shift itself does matter if you know people in locations that do not observe

It's not so black and white. From what I've read, radio altimeters operate in the 4.2-4.4 GHz range, and the 5G spectrum in question is 3.7-3.98 GHz. RF systems generally work by choosing a center frequency (say 4.3 GHz for altime

Because it's a proof of concept using an ESP32, not because that battery capacity is fundamentally necessary for the idea to work. It could easily be optimized for power and size. Sure, it will have to use more power than a vanilla air

Are any of these models any good? Every one I tried was pretty horrible

Cadence, et al, came up with the "OpenAccess" for circuit design databases in the early 2000's. Needless to say... it's not very open. Hopefully this is different but I'm not holding my breath. "OpenAccess is a

Unfortunately it has some pretty severe limits on where you can place the seating which makes it completely useless for my totally average setup (11x12' living room with tv on one wall and the couch on the back). Sure, it's not op

I think you're missing the point of the comment. It's not "don't use cloud". It's "be prepared for when cloud goes down". Because it will, despite many companies either thinking it won't, or not

It bugs me that the toolbar now takes up more vertical space than before. Not only does the padding just look funny, but vertical space is a premium in widescreen layouts! C'mon Microsoft!

Pretty much every major company in the space will have a team or even several dedicated to digital IC security. Qualcomm, Intel, Apple, Mediatek, Xilinx, and probably Google and Amazon now as well. I attended a really interesting pre-COVID

I hope this eventually leads to the ability to remove ads. It's unbelievable to me that you can pay top dollar for a high end OLED tv and it will still drown you in ads and notifications. I ended up just disconnecting my tv from the in

That did not come across as defensive at all to me. It was pretty clearly tongue in cheek. Your comment, in fact, comes across as judgmental and condescending

Analog and RF circuits are laid out completely by hand! But there are often a lot of symmetries and repeated structures that mean you can re-use a lot of layout. Also, designs are often copied, reused, and repurposed, so those layouts just

Huh you might be right, if only just. It says it's an estimate, but that probably means 3nm nodes will be >$10MM for sure

I'm not very familiar with the details, but I know this is an active area of research. Generally you use a process thats conducive to optics (like SOI), you fab the regular silicon in some areas, and you have separate process steps to

I think the first step is making EDA (electronic design automation) more accessible. Right now, even if you could do the fabrication yourself, doing a real, useful design would be just as challenging because the tools are all proprietary an

That sounds way too high for mask costs. You're definitely looking at 7 figures, but I don't think they've yet hit 8. Unfortunately the answer to all of your budget questions is: it depends. It's going to scale with the

With most open source hardware efforts, like this, it's not really so much circuit design as it is just code. All of the open source efforts I've seen revolve around digital circuits, which are written in some kind of RTL and turn

No, I don't think so. But it's not because of the chemicals or machines. There's not really any demand for it. Most hobbyist "ICs" are fully digital and can already be realized on an FPGA. For simpler applications,

The US may have technological supremacy when it comes to design and the resultant products, but it lags behind in terms of actually manufacturing semiconductors. The dominant players are in Asia (TSMC, Samsung, GF) and Europe (GF). Intel ha

I think the Baker book is good for an overview. I also used Pierret's Semiconductor Device Fundamentals in undergrad. It goes more in depth for device physics than it is a pure manufacturing text, but I recall it also had a nice overvi

This is one area the article did a very poor job of explaining. In some processes, you treat the entire wafer before you get started with the rest of the procedure. One example that does this is SOI (silicon on insulator) processes. Others

For circuit design or manufacturing? I haven't been in school for a while, so I'm not sure what's current. I really liked Baker's book - CMOS circuit design. It had a decent overview of the manufacturing process for the
