Back in 1994 I was a sophomore in college. In our C++ class I asked the professor how GUI programs were written and she suggested the Motif toolkit for Unix / X11. I checked out a book on Motif from the library and I had to type in a

I remember playing this on my roommate's 386 DX 33 in 1992. It was way too fast so we had to hit the turbo button to slow the CPU down to 16 MHz in order to not immediately crash because it was too fast to control

After reading Dava Sobel's book 20 years ago I made sure to go to Greenwich to see the clocks when I was in London in 2005. They are both amazing engineering and works of art.

Is PostScript still used in printers? Someone already mentioned NeXT and NeWS. I loved Solaris and NeXTSTEP when I was in college in the 1990's. At the time every computer lab had an HP printer with built in PostScript. When I got m

That is really cool. I've been in the industry for over 25 years and I've never been to a fab. The number of jobs and specialization is so high that you need thousands of experts in their area but they have little knowledge abou

What's interesting to one person can be boring to another. I'm assuming you are on the analog side and find that stuff interesting. I'm on the digital side and was in a serdes team for 10 years and I'm glad to be gone.

I interviewed at Open Silicon in 2010 and had a few friends that were there from 2010-2013. I'm in physical design and they had a big PD team but it sounded like a sweatshop where they just bend over and do whatever ridiculous crap th

Thanks. I totally missed that. I knew people at Open Silicon around 2010-2014 and interviewed there but didn't join. This industry is so small you run into the same people again and again.

Yeah, that team switched exclusively to the server chip which was cancelled a few years later and they laid off 500 engineers in that team.

It takes $30 million for masks in 5nm. EDA tools for physical design are over $1 million per instance and you may need 20 to 200 licenses for a big chip. Total compensation for engineers is in the $150K to $400K range in the US. This isn&#

Are you asking why VLIW hasn't caught on? There are DSPs that use VLIW concepts. But for general purpose computing look at Itanium and it's failure.
