The 6502 didn't need cache because its clock speed was slower than the DRAM connected to it. That made memory accesses very inexpensive. The Apple II took advantage of the speed difference between CPU and DRAM and designed the video ha

I have a NUC running Debian for 8 years as a fileserver for my home, with 2 x 2T USB HD. It was slow (USB2) but fine for the intended use of mostly cold storage. I recently replaced it with a Synology Diskstation, looking for a new job for

No mechanical turrets needed! Just use a flat, stationary, phased array infrared emitter.

That's not what I took from the article. The tax incentives for construction are the same as other regions (that's what"competitive" means in my summary). The tax incentives are needed to compete with those other regions

Tax incentives (competitive) + energy prices (competitive) + population (20% of us in southwest) + connectivity The above outweighs cooling costs.

If I've learned anything living in central Amsterdam, it's that a healthy city has a mix of all transit options almost everywhere. Cars, bikes, motorcycles, scooters (the vespa kind), mopeds, buses and trams all mix with pedestria

I'm a big fan of pigz. I use it in my home-grown backup script for my Linux laptop. It can compress the incremental tar output from my filesystem snapshot fast enough to saturate the I/O to my external USB3 hard drive. This is a l

Thanks for the great perspective. I want to say that "if there was something off the shelf that met all our needs we would've used it" has been the justification for many over-engineered, not-invented-here projects. On the ot

This article never really answers the headline question, it just asks more questions. That said, it does have a nice summary of how Mastadon and Blue Sky are different, and captures the angst felt by journalists who found success on Twitter

The article makes the common (and grating) error of conflating power (1.5 gigawatts) and energy (power over time). Put another way, "1.5 gigawatts" does not in any way describe a rate. Do they mean 1.5 gigawatts per hour? or per d
