I think the bigger question is does RISC-V need to be fast? Who wants to make it fast? I'm a chip designer and I see people using RISC-V as small processor cores for things like PCIE link training or various bookkeeping tasks. These

Jeff Geerling had a video of using 4 Mac Studios each with 512GB RAM connected by Thunderbolt. Each machine is around $10K so this isn't cheap but the performance is impressive. https://www.youtube.com/watch?v=x4_RsUx

I remember I started my internship in June 1995. We were doing stuff with this brand new thing called the World Wide Web. They gave us a win3.1 computer and Spyglass Mosaic which required the Win32s susbsystem. http://www.win3x.

My feeling at the time was that BSD developers and many users were at least 30 years old or much older and had professional jobs and money. The Linux community felt like college students with no job and not much money. That included Linus T

I went from Slackware in 1994 to Red Hat in 1998 to Fedora when they split into Fedora and RH Enterprise. Every 2 or 3 years I will install a different distro in a VM and see "Okay, now I see what it's about." But I have n

10 years ago Instagram was great. I would see 10 posts from friends, 1 ad, and 0 posts from people I didn't know. I gave up about 4 years ago as I was seeing 1 post from a friend, 3 ads, and then lots of random stranger posts. My frie

Broadcom does the physical design and sources a huge amount of the IP like serdes blocks. TSMC manufactures the chips.

MS wants control and they will figure out some way to monetize that control. Whether it is using the data stored in the cloud for AI training or something else. If you want control then install Linux or get a Mac. I installed Linux in 199

I started working in 1997. Cisco was one of our big customers so I knew a lot of engineers there. Cisco stock hid $80 in 2000. In 2002 it was at $10. https://finance.yahoo.com/quote/CSCO/ I knew people who purc

I first got on the Internet in 1991. The older students told me to lurk on Usenet and not post anything for a month or 2 to avoid getting flamed. I did and then I loved it. Once all the @aol.com people started showing up it went downhill

I've been designing chips since 1997. The first 2 companies I was at had their own fabs. It's been a boom and bust industry for 50 years or more. https://www.macrobusiness.com.au/2021/05/the-great-semic

I started off using twm / olwm / vtwm in 1991. Then FVWM and Afterstep / WindowMaker. I've been using XFCE since around 2007. As long as it functions similarly I'll be happy.

I've been doing this for 30 years. Blocks are never 100% full. If it was then you would never be able to route the design. High utilization may be 70% but if a block has tons of IO then I've worked on blocks that are only 25% ut

The other alternative is that you sprinkle spare gates around the chip. If the chip is 10mm x 10mm then every 100 microns you put a group of cells that just have their inputs tied to 0 and the outputs go nowhere. You put in a good mix of

If the change is under 1000 logic cells and no new flip flops then we do a it as an ECO. If there are tons of new flip flops we resynthesize and start over. Lots of chips have metal spins to fix errors. The blank areas of the chips are fi

I've probably worked on 70 chips over the last 30 years. Tape out time always sucks. I'm in physical design which is fixing all the timing violations, DRC violations, LVS errors, and dealing with late design changes. Working 80 t

Bots have ruined reddit but that is what the owners wanted. The API protest in 2023 took away tools from moderators. I noticed increased bot activity after that. The IPO in 2024 means that they need to increase revenue to justify the stock

Why did BSD make Unix sockets something outside of the file system? I can do this in bash but I always thought it would be more elegant to do a similar thing in C. I thought Plan 9 handled it more like this? cat < /dev/tcp&#x2
