Tire noise is the major contributor at speed, and it looks like even in a typical US residential street with 20-25 mph speed limits, tire noise already dominates.

Note that they can claim to guess a location based on reasonable clues, but actually use EXIF data. See https://news.ycombinator.com/item?id=43732866

Maybe it's not what happened in your examples, but definitely something to keep an eye on.

That actually happened at my job a few years ago, where some extra power draw off a power supply that was also feeding a PC would slow down the code running there. It does sound crazy...

> the problem that now reviewers have to figure out what changed

That's something that the review tool can solve, and I agree that github doesn't handle it well. But other code review tools can show diffs between revisions independently of how the commits have been rebased or squashed over time.

Thanks for writing lnav, it's a fantastic tool. I constantly take advantage of the automatic benefits you mentioned, and also love the ability to navigate a log minute by minute, interleave multiple logs within the same timeline, navigate through errors or warnings, and how easy it is to deal with spammy logs by using filter-in and filter-out. Thanks!

I think it's unfair to characterize this as a layman's myth given that it was a widely quoted figure in the literature at least until 2016.

I buy Bob's Red Mill "Old Country Style Muesli" in the US. It is the only one I've found with zero added sugars. Most grocery stores in my area seem to carry it tucked away somewhere.

Your recipe looks nice, but some dried fruit has a bunch of added sugars, so that's something to keep an eye on though.

Luckily the original data from that day is available, so you can see [1] that the actual temperatures recorded in Zaragoza and several other cities nearby were far from that extreme temperature.

Other Spanish newspapers reported the extreme temperature as taken in the sun [2], and also included the temperature in the shade with a more reasonable value.

All those leaks contribute to the externalities of natural gas. I don't know the relative contributions between extraction and distribution, but leaks in the distribution network are also a problem in Europe [1]. It's certainly true that extraction leaks can be so substantial as to make shale gas worse than coal [2] (twice worse over 20 years!).

Landfills (and agriculture) are big sources of methane. I think this is a pretty good start to figure out what the EU is doing to reduce all sources [3].

This will depend on the specific threat model for the sensitive data you are dealing with, but generally files in an SSD can't be destroyed securely (and shred specifically does not help due to wear leveling).

Instead, you may want to encrypt your disk so that as soon as the key is gone it all becomes unreadable. For a bigger threat, maybe you need to follow the NIST destroy guidelines [1] to "Disintegrate, Pulverize, Melt, and Incinerate" the media.

It may be worth insulating it first. It cost me just about $1500 to go from effectively no attic insulation to R60 for a thousand sq ft, and besides making a massive difference in comfort it reduced energy usage by about 50%.

Maybe you're being hyperbolic, but the catastrophic engine separations in the Stratocruiser were due to propeller failures.

pinkorchid — Fri, 19 Aug 2022 01:16:53 +0000

Altitude is definitely a challenge, but I don't agree that peaks below 4000 m are amateur mountaineering and elite is reserved for 8000ers. As an example, Marc-André Leclerc made some incredible first solo ascents below 4000 m like the Corkscrew on Cerro Torre, at 3128 m (10,262 ft). The Alpinist [1] is worth watching if you are into mountaineering!

The Moderna booster is actually a half dose, although I don't know if it tends to have stronger side effects than the first two full doses.

The law that you linked says that drivers aren't allowed to drive at an unreasonably slow speed, and defines that to be (for highways, with good weather, and just on the leftmost lane) 80 km/h.

It doesn't say that the speed limit is a target, or that you're supposed to drive at or near it.

New comment by pinkorchid in "3½ years on my custom emperor mattress – a retrospective"

pinkorchid — Sat, 30 Oct 2021 05:11:59 +0000

My partner and I lost a good chunk of our clothes and lots of time to a cheap $300 mattress. The fiberglass in the firesock leaked, and the first symptom was a very itchy running t-shirt. It took us almost a week to figure out what was going on. The tiny fibers are essentially impossible to remove, and very hard to see unless you know what to look for.
