If anything, events in recent years where poopy proprietary software affected millions of users reinforced my view that people who demand FOSS and reject...

You have all rights granted to you under the GPL even if you disagree with it. This is a very important distinction from an EULA.

Possibly a case of NIH syndrome. NVidia rather works on their own driver than on someone else's.


Not sure about your other points....

Many things inside and outside the forums link to http. For example the link at the top of each article discussion.

Librem won't help you, because they face the same issues with modern hardware. Firmware blobs galore on baseband, wifi, bluetooth, etc. Maybe they can...

Due to memory prices and availability, I decided to not order that ECC kit now. Instead I ordered a G.Skill F4-3466 2x4GB (non-ECC) when I found a very...

I specifically said there was no bug in the IOMMU or elsewhere. The particular attack was controlling IOMMUs before the operating system could, and hiding...

I'd caution against the line of thinking that the mere existence of an IOMMU on a system will make things secure. In practice, IOMMUs have bugs, system...

Using icc to compile your whole distro often is a bad idea. icc is known to take standards-violating shortcuts by default (especially in fp code). There...

None of the big mobo vendors officially support Linux. Their first-level support will either refuse to help you, or will forward your support ticket to...

With ffmpeg this is not surprising, since ffmpeg employs runtime CPU detection to automatically switch code paths. With -O3 and potentially other options...

I don't know what "allowed even at O2" is supposed to mean. It happens at -O2 if you enable -mfma explicitly or indirectly through -march=......

Given that Debian is very stability oriented, I don't think they can follow all of those.

Using contractions like FMA will potentially affect...

The average case will see a very small but measurable benefit. But if your code starts spending major time in kernel space (e.g. the recently mainlined...

If you want to run the Linux kernel with CPU-specific optimizations, you need additional patches (cf. https://github.com/graysky2/kernel_gcc_patch, integrated...

It seems that Michael is not willing to do benchmarks on Gentoo.
About -march=native, that is not the whole story when it comes to...

While this may be true if you run the code in isolation (assuming the compiler uses correct information on L1 cache size etc.), in a scenario involving...

NVidia Kepler cards with two DisplayPort outputs should do.

A few Geforce cards like the MSI Gaming ITX 760 have two (mini-)DisplayPort outputs,...
