This is why IX like Torix lock down switch ports to a single MAC address and limited protocols (ARP, IPv4, IPv6). It's a bit of a pain when first setting up peering, but it reduces the exposure for all those connected to the IX. The

Back in the late 1990s I worked on firmware for a dual PRI ISDN card that used an i960, and was quite impressed with its performance. Register windows made interrupts surprisingly performant. The hardest part of that project was fixing a

The P4's main problem wasn't so much the 30 stage pipeline. It was the fact that the CPU went off into la-la land for 4000+ cycles when replays occurred. The trigger could be anything as simple as a misaligned load or microcode

ext4 has its own issues usually more in terms of scalability. XFS is trustworthy without the glass jaws ext4 has all over the place. Ah, the joy of taking 80 seconds to write out an 8MB file to disk after a fresh mount....

I am disappointed that the top voted comments are so supportive towards yet more generation of AI slop. Sites like this are making accurate search results by people for real world products that exist harder to get in front of the eyeballs

Kinetic UPSes can fit in that niche. They're not exactly expensive to build, nor is there any new technology that needs to be developed. Like many power grid improvements the constraining factors are will and money.

Err, that's expected of every submission to a maintainer of the Linux kernel. If one doesn't do that, maintainers are going to notice eventually and stop trusting the patches sent by a person with such a poor reputation.

Newer coherent optical transceivers don't need physical dispersion compensation as they just do it in digital signal processing instead. That is the magic of ever increasing rates of computation at lower power expenditure.

Even if a pole is taken out by a drunk driver that does not mean the cables are going to be severed. I've seen plenty of times when poles had to be replaced, but the communications cables remained undamaged in place due to the strengt

Too expensive where I live. Rocks, hills and trees: the natural enemies of buried fibre and wireless networks. One of my competitors took 6 months to bury a cable in granite that would've been a 5 day aerial job.

In telecommunications construction we are taught to make ample use of the "hammer test" when working on and around poles. The difference in sound between a good pole, a marginal pole and a completely rotten pole is quite signific

For tuned, I don't need the bug fixed, as I simply don't want it changing any kernel settings at all. Uninstalling it achieves the result that I want. The rest of the rant is valid and the issues are virtually impossible to get f

If they plan to shut it down for Foundry customers, there's probably a "yield issue" that is being hidden from the public. Last time there was a "yield issue" it turned out to also be a reliability issue. 18A intr

It's easier to uninstall it. There's nothing good that tuned has ever done for me. FYI: messing with irq bindings for per-cpu queues of nics has been a bug for at least 16 years depending on the nic. FYI: Intel launched the 8259

The Amiga 500 I had made that even more awesome: there was +/- 12VDC on a couple of the pins of the serial port, and the parallel port had +5VDC. Hot plugging was very dangerous as a result. The crazy part is that the Amiga 1000 had

I disable it whenever setting up a new system. It gets irq bindings for networking wrong every single time, and moves irqs around in ways that defeats the whole point of having per CPU queues. Not sure why that behaviour is enabled by def

Maintaining fab capacity requires product to run through that fab. Intel no longer has enough volume to maintain that on new advanced nodes (yeah, farming out CPUs to TSMC is super helpful on that front), and nobody wants to be a foundry c
