I started developing wrist pain in the early 1990s when I was a teen. Thankfully, I eventually figured out that changing keyboards and the way I positioned my hands resolved the issue.

The prior rumours that Jim Keller had AMD develop the K10 core with the option of using an ARM front end would have created an extremely interesting way to compare the merits of the 2 instruction sets. x86 has constraints that make it far

Read-Copy-Update has been around for quite some time, but the fact that it was patent encumbered meant that its usage was limited. IBM made the patent available for use in the Linux kernel, and now that it is expired, the technique is bein

The past 30 years of the Linux kernel's evolution has proven that there is no need for a stable kernel ABI. That would make refactoring, adding new features and porting to new platforms exceedingly difficult. Pretty much all of the p

The Linux kernel community takes ABI compatibility for userland very seriously. That developers in userland are frequently unwilling to understand issues surrounding ABI stability is not the fault of the Linux kernel.

They're not a problem until they are. I recently had a molar out likely due to damage from an impacted wisdom tooth I had out years ago. The rear of the molar was compromised on the back, and there was no way to save the tooth. If I

Evolution isn't the only thing that is needed. Culture matters. Individual learning experiences matter. Take texture of an object that you see: as an adult you can probably look at it and know how it will feel if you move your lips

The problem is the corn subsidies. If they weren't distorting the market, crops other than corn would be viable in many places currently growing corn.

It's just like how we once used UUCP and Fidonet for email / news / message boards to remote systems that only had intermittent dialup connectivity in the 1980s and 1990s. Pockets of local communities would pool together to

It's the misalignment of software developers' interests with those of end users that makes old systems unusable. Do we really need web pages that stream 4 video ads on loading and have another pop-up over top of the content the u

I was traveling a lot at the time. Carrying lots of physical CDs without damaging them was a pain.

I lived through that period, too. Tape was never a long lasting medium. As you listened to your favourite albums over time, the tape would stretch and the must would sound different over time. Especially if you left them inside a vehicle

Context switches and interrupts were also pretty quick on itanic as well. Modern x86 has so much cruft that it Would Be Nice if those parts could be re-architected, but it's more like to just become more legacy baggage carried on into

It appears to be atomic to the application as viewed from userland (and it is should no crash occur), but it is not guaranteed to be an atomic operation on disk should the system crash at the right point in time. Whether it is atomic on di

You have made a false assumption: directory operations across directories are not atomic. The typical way around that is to hardlink the file into the target directory and then sync the target directory then delete the old name, but now yo

Some of those results were due to the substantially better memory subsystem that itanics had compared to x86 systems of the time.

Telecom is not more affordable today than it was in 1990. Back in 1990 the private phone line we shared at home for a family of 4 primarily to support connecting to local BBSes and the internet cost $20/month, or roughly $48.65 in 202

Did you read the whistle blower commentary on internal notes on the plane that had the door plug blowout? It wasn't a supplier issue: the people inside the factory had an off-the-books message board that directly discussed what happen

I think the big difference is that engineers have had to care about people dying for the past 100 years. Today there are software developers that throw code out into the world that kills people without any repercussions. At some point thi

That's 25 MHz if you're doing everything serially, but you could probably do it with a 11 or 12 bit parallel bus. There are ADCs on the market that have parallel rather than serial interfaces. The only reason I'm suggesting

Anywhere that icing is possible during the winter, the static weight of the conductors is not generally the dominant design constraint; it is the diameter of the cable and the resulting additional load when icing occurs. Weight really only

Colocating batteries with panels should be more cost effective as they can avoid the DC-AC-DC conversion while using half as many inverters as 2 separate installations.

You can actually run GPON and XGSPON simultaneously over the same PON segment as they use different wavelengths of light, so there is no reason to rip out all the GPON nodes at the same time. This allows deferring the truck roll and ONT co

PON generally uses PLC splitters which are pretty much wavelength agnostic, so you don't even need to swap out the splitters in outside plant. It it entirely possible to overlay DWDM wavelengths on PON segments without even removing o

I find it baffling that the difference in cost of serving 41GB/day vs 232GB/day is worth spending any dev time on. We're talking about a whopping 21.4Mbps on average, which costs me roughly CAD$3.76/month in transit (an

25kSps sounds like it would work well using something like the RP2040. The PIO blocks would let you implement the sampling triggers with decent realtime accuracy, and it's an order of magnitude cheaper than most FPGA boards. External

At a high level, FC lost the write without responding to the write in a timely fashion while other I/Os went through. The write request never gets through from the host to the target, and the host ends up timing out the write then thr

After years of dealing with colocation, I would never deploy a server without KVM in a data center. The cost of truck rolls is just too damned high! Even with KVM, I have had to make an emergency trip to a data center that is a 3.5 hour d

Adapter PCBs still have to be emission and safety tested before you can start selling them. I have family in Germany that had been making and selling bee scales for almost 25 years across Europe up until compliance became extremely costly

Last time I checked, multipathd does not and cannot detect faults on the write path as it only performs small reads to check the health of any given path. Checking writes would involve allocating space on the disk for multipathd to safely
