Very unfortunate timing given the ongoing wildfires and associated smoke spreading across eastern North America in recent days.

There's an agreement to do something about leap seconds before 2035, either by allowing DUT1 to exceed its currently specified bounds (this is most likely) or by agreeing to simply not insert/delete leap seconds going forward (thi

Fortunately, in the past couple months, the likelihood of actually needing a negative leap second in the next few years has been trending down. This is based on measurements and predictions done by the IERS, the data for which they publish

I have a machine that's on a Debian installation that I've been steadily upgrading, one Debian stable release at a time, since I originally installed it about a decade ago now. At one point I even copied the entire installation to

They bought P.A. Semi, but it was for their design capability; they never had fabs anyway, and Apple still depends on TSMC and others for manufacturing chips. Apple building fabs to ensure a guaranteed supply of memory (or logic) chips woul

I made something similar a long time ago partly as a challenge to see what could be done with just 2 KB RAM [0]. It was possible to implement some very basic context switching between two "processes", pipes (okay, I only had a sin

~450 square feet, with how many feet in the third dimension? You probably had an order of magnitude more volume than 330 cubic feet there.

This is really fun! A possible bug though: I managed to finish Inverness to Gibraltar, and the top three spots on the leaderboard somehow had negative time durations!

My intuition would be that constant usage (not exceeding maximum rated capacity/thermals/etc.) should generally result in less wear compared to the more frequent thermal cycling that you might expect from intermittent use, but may

But if everyone follows this advice, then everything just gets overwhelmed by "hustlers" (and their "shameless spam"), and collectively we're now all worse off because of it. It just turns into yet another tragedy o

The total size isn't what matters in this case but rather the total number of files/directories that need to be traversed (and their file sizes summed).

If that's really the case, I wish they would just come out and say it and spare the rest of us the burden of trying to debate such a decision on its technical merits. (Of course, I am aware that they owe me nothing here.) Assuming this

Maybe the thought is that there will be more pressure now on getting all the tests to pass given the larger install base? It isn't a great way to push out software, but it's certainly a way to provide motivation. I'm person

I can certainly understand it for something like sudo or for other tools where the attack surface is larger and certain security-critical interactions are happening, but in this case it really seems like a questionable tradeoff, where the b

I'm not going to speculate about what might be ahead in regards to Oracle's forecasting of data center demand, but regarding the idea of efficiency gains leading to lower demand, don't you think something like Jevons paradox

The industry definitely seems to be going in this hybrid PQC-classical direction for the most part. At least until we know there's a real quantum computer somewhere that renders the likes of RSA, ECC, and DH no longer useful, it seems

There's also a lunar occultation of Mars (which is near opposition itself, making it relatively bright) happening in a few days, and then again in February, which should be visible from parts of the northern hemisphere: https:/&#

It looks like there's also a fix for that nested virtualization bug causing host reboots on Ryzen 7000/8000 CPUs [0]. It's nice to see that the cause appears to be known and that it's being addressed (even if the kernel

For some reason this also made me think of the boundary of the Mandelbrot set...that place where all the interesting structure reveals itself.

It depends on the type of sailing and where the race will be taking you. The participants in a race such as the Vendée Globe [0] are almost certainly using the likes of synoptic scale models like the GFS and ECMWF to plan their routes. [0]

The GFS is a coarser model which covers the entire globe, so while the overall situation at the synoptic scale will tend be modeled quite well (at least inside of a few days into the future), the resolution of smaller-scale weather phenomen

Since light travels at 100% the speed of light in a vacuum (by definition), I have wondered if latency over far distances could be improved by sending the data through a constellation of satellites in low earth orbit instead. Though I suspe

Obviously, nobody is going to outright admit they put profits above security; indeed, they will often state the opposite. But their closely-held beliefs will shine through when it comes time to make decisions and the outcomes of those decis
