I know this is about Power9, but these benchmarks really make me look forward to a time when companies will be ditching these first gen AMD EPYC processors on eBay for cheap. Good times are coming.

They used CSS to create the font (presumably as an art project?), but it is available in plain OTF/TTF format, so it can be used as a normal font and doesn't need to be a barrier to accessibility tools.

This seems like a classic case of annecdotal evidence being extrapolated into general truth. Two kids from an identical environment and sharing the same ancestors are hardly a significant sample.

Decelerating doesn't mean that it's no longer growing. It means that growth is declining over time, so growth today is less rapid than growth a year ago. That doesn't mean that growth will stop, though it might.

That's true, but the port work described in this post is older (predating the fork of LEDE and OpenWRT), and the latest work regarding these zsun devices are more recent (but they haven't been upstreamed into LEDE, and so haven&#x

How does this work for two instructions in the pipeline at the same time that refer to the same cache line? If the second instruction executes the read phase before the first is retired/committed to cache, you would be hit by two memor

Sure, but then you still don't have V-Sync, which causes terrible and easily noticeable tearing on almost anything (at least in the case of Nvidia, it seems to be much better with AMD from my annecdotal testing). I doubt Apple would fi

Weird how they include an HD 630 on the die. This eats up a fair chunk of die area, and eats into the thermal budget. It also means that the displays will probably be wired to the HD 630, so the Radeon can power down to save power. Taking o

Sure, but it's still part of the outside world, so it's still opening a lot of extra interface surface to the platform.

This always manages to put a smile on my face. This is a pointless but awesome technical achievement, and in the spirit of the old definition of "hacker".

I've found that doing anything distracting can help. Commuting, listening to a podcast or audio book, playing a video game for 15-20 minutes, ... Whatever takes your mind away from matters at work.

For big metal rigs like supercomputers, there is almost no choice but Linux. Combined with Linux' dominance of the server market in general, there's a risk emerging to get stuck in a monoculture on the OS layer. Most companies, in

That's interesting, I'd not seen this comment before. So the good thing about System76 is that they can gather up the Linux users buying their products, and use the volume of those combined sales to give Linux users a voice with u

Sadly, no. I've tried to find out but couldn't find any clues. As far as I can tell, they're using their own custom built casing. It definitely looks much better built than the Clevo machines, but I've not yet have been

Sure, but implied in their Linux branding of the laptops is a promise of testing their configurations with Linux. So you are paying for a promise that the system will be compatible with Linux, I suppose. If these things interest you, you sh

No, but I can tell they're just rebranded Clevo builds. These machines have very decent specs and are easy to service and upgrade, but at the cost a of very low quality build with regards to the laptop case itself. There are plenty of

What you need is a massive amount of parallel cores. Currently, the cheapest and most efficient way to achieve this is GPUs. It's true that some graphics-specific parts of a GPU are not needed for compute-only kernels (such as those fo
