Forwards is up, up is back, back is down, down is forwards.

DO has been shockingly reliable for me. I shut down a neglected box almost 900 days uptime the other day. In that time AWS has randomly dropped many of my boxes with no warning requiring a manual stop/start action to recover them... But everybody keeps telling me that DO isn't "as reliable" as the big three are.

I put a little analog clock on my desk that's set to UTC time. It helps a lot with converting logs to get a quick reference.

Another great lens to see this is "Normal Accidents" theory, where the argument is made that the most dangerous systems are ones where components are very tightly coupled, interactions are complex and uncontrollable, and consequences of failure are serious.

This is another case where it's highly important to "plant your flag" [1] and set up all those services like Search Console, even if you don't plan to use them. Not only can this sort of thing happen, but bad-guys can find crafty ways of hijacking your search console account if you're not super vigilant.

Google Postmaster Console [2] is another one everybody should set up on every domain, even if you don't use gmail. And Google Ads, even if you don't run ads.

I also recommend that people set up Bing search console [3] and some service to monitor DMARC reports.

It's unfortunate that so much of the internet has coalesced around a few private companies, but it's undeniably important to "keep them happy" to make sure your domain's reputation isn't randomly ruined.

Even a radar reflector would have helped a lot. ADS-B is off-limits for balloons, ultralights, hang-gliders, etc, and it seems like now that radio beacons can be manufactured very cheap & low power all those non-commercial aerial vehicles should be equipped.

It's not inherently an American thing, it's the result of several mid-century zoning and urban design decisions.

I used to live in a 1920s era "streetcar suburb" neighbourhood. I lived on the third floor, and the ground level was a full (but small) grocery store. I never spent more than ~$50 at a time on groceries because I only bought for a couple days at a time.

The same decisions and laws that created the current system can be changed to take us back to the "norm" in the rest of the world.

Note that this affects ".net core", not ".net framework"

I'm pretty "curious" when it comes to public networks. I'll scan coffee shops, stadiums, hotels, bus hotspots, anything I can connect to. Some networks are set up well, others not so much.

I would never in a thousand years run a sweep on an airplane network. That's massively risky, to the point you might never be allowed on a jet again. Anything to do with aviation I am on my absolute best behaviour.

It's a culture problem. The real solution is to teach people to trust their security department.

If there's trust and respect, they'll reach out without fear of reprisal and inform right away when there's a problem.

If there's a culture of punishment, they'll fear the IT gestapo and try to cover up mistakes that could cost them their job.

It really is that simple.

Absolutely agree. I'm a huge fan of co-op type ownership structures for this reason. They might not be moonshots or unicorns, but they always have longevity.

An IX is the internet, or at least a small part of it. It's sort of a network where each device shares their "routes" with the others, and then propagates those routes back through their own network. They're exchanging their respective pieces of the Internet with each other.

The devices themselves are just routers, though much larger and more complex than what you'd see in a house or office. Instead of one route, "put all the traffic through eth0", they'll have hundreds, thousands, or millions of routes depending on their location relative to the "rest of the internet".

The storage itself is probably (mostly) on HDDs, but I'd imagine metadata, indices, etc are stored on much faster flash storage. At least, that's the common advice for small-ish Ceph cluster MDS servers. Obviously S3 is a few orders of magnitude bigger than that...

I hope that this is used to strengthen privacy laws. But I know this will be used as pretext to enforce dubious "age verification" like we've seen in other countries.

I've toured a '60s era Cold War diesel-electric sub that's been a museum for ~20 years, and it still absolutely reeked of diesel. Combine that with the smell of a couple dozen dudes that haven't showered properly in weeks, and your answer would be not good.

The long-term health outcomes are probably significantly worse for people that served in diesel subs than nuclear because of the constant exposure to fossil fuel volatiles. Just being in there for a 20 minute tour made me feel like I just smoked 20 cigarettes.

One of the bigger issues is the double-hop problem. It's both an important security boundary, and one of the biggest butt-pains about the protocol.

It works great within a single organization hierarchy, but becomes pretty painful for anything we'd consider "SaaS"

SSDs are worth it to me because the restore and rebuild times are so much faster. Larger HDDs can take several days to rebuild a damaged array, and other drives have a higher risk of failure when they're being thrashed by IO and running hot. And if it does have subsequent drives fail during the rebuild, it takes even longer to restore from backup. I'm much happier to just run lots of SSDs in a configuration where they can be quickly and easily replaced.

> So: the matrix.org database secondary lost its FS due to a RAID failure earlier today (11:17 UTC). Then, we lost the primary at 17:26. We're trying to restore the primary DB FS (which could be fastish), while also doing a point-in-time backup restore from last night (which takes >10h). We believe the incremental DB traffic since last night is intact however. Apologies for the downtime; folks on their own homeserver are of course not impacted.

The stuff of absolute nightmares...

Best of luck to the team at Matrix/Element for restoring from a nasty outage.

You can take decades old fibre, stick some new transceivers on the ends, and have it run at the very latest speeds (unless it's cheap, damaged, etc) without having to pull it out and reinstall it.

H100s will not age this well. It's not like owning old railroad tracks, it's like owning a fleet of 1992 Ford Taurus's. They'll be quickly obsolete and uneconomical in just a few years as semiconductor manufacturing continues to improve.

Expanding on the other comment, it's the mixture of snow, slush, salt, and loads of sand/grit that gets churned up by car tires into a brown and sticky slime. It sticks to boots, gets caked on cars behind the wheels, and gets tracked shockingly far into buildings. It's sort of like a "slushee" consistency but made out of nasty brown goo instead of corn syrup.

More northern cities like Montreal and Winnipeg also have very interesting indoor pedestrian systems. The one in Winnipeg is particularly useful, since there are approximately 72 hours per year that it's comfortable to be outside between the bone-chilling cold and the biblical swarms of mosquitos and flies in the summer.

Mazda punches way above their weight when it comes to "moonshot" innovation over and over again. Few of them really "succeed" commercially (Rotary engine, miller-cycle engine, HCCI) but I respect them for constantly pushing the technology forward.

Surely this is just the link between financial well being (having enough money to spend on high quality food) and mental health? I guess "people with enough money to afford the food they want" isn't as catchy of a headline...

My understanding is that it just increases the "expense" of mass crawling just enough to put it out of reach. If it costs fractional pennies per page scrape with just a python or go bot, it costs nickels and dimes to run a headless chromium instance to do the same thing. The purpose is economical - make it too expensive to scrape the "open web". Whether it achieves that goal is another thing.

The only thing worse than "it's down" is hearing "it's down again"

Godspeed, IR workers...

Automotive design really peaked between 1995 and 2010. Timeless "regular car" designs like the Panther body, the 4th gen VW's, the E46 BMW's, Astro vans, Ford Rangers, etc. I'm sure my late-millennial nostalgia is making me see the past with rose coloured glasses, but things really are dull today [1]. It was really the confluence of the right regulations, slowly increasing fuel prices making innovation necessary but not highly urgent, and value engineering still being primitive enough that nobody was quite ready to stomach stuff like CVTs.

Nowadays, manufacturers and dealers are taking advantage of emissions regulations to turn everything into a "light truck" or SUV, leading to the most bland and uninspired designs. A body used to be designed by one small team, now every panel has its own focus groups and the cohesive whole is completely lost. And of course, value engineering and simulation is so sophisticated that Nissan and Chrysler can make your engine blow up exactly 1,000 KM past the warranty interval.

I wonder if it will be the same cause as the big Rogers outage in '22, a good old fashioned BGP botch.
