Some Facebook employees who had returned to working in the office were also unable to enter buildings and conference rooms because their digital badges stopped working. Security engineers said they were hampered from assessing the outage because they could not get to server areas.
Edit: Even more LOLs:
Inside Facebook, the outage has broken nearly all of the internal systems employees use to communicate and work. Several employees told The Verge they’ve resorted to talking through their work-provided Outlook email accounts, though employees can’t receive emails from external addresses. Employees who were logged into work tools such as Google Docs and Zoom before the outage can still use those, but any employee who needs to login with their work email is blocked.

@dcon that makes me unreasonably happy.

@dcon Could become a peaceful day, if only there wasn't twitter available...

… … w-w-w-what's the point of such email? In my experience a work e-mail is primary means of contact with business partners (whether that means customers, subcontractors, vendors of various software etc.). Even lowly programmers need such contacts sometimes.
-
@Bulb I'm guessing that in normal times that stuff works, but it didn't when all their internal network was down because it required some sort of step (probably something like an LDAP check) that looped into the network zone that was routing-dead. It's all to do with whether the operation can be carried out without routing packets into or via the affected network, but that's normally a factor ignored by everyone.
Fully private emails wouldn't have been affected. Why would they have been? It's the integrations that had the sensitivity.
I've seen things like this happen at work, but then it only took out a quarter of campus, the services impacted were almost all internal, and the outage shorter.

@dkf It sounded more like the can't is generic condition, but you might be right.

Facebook's incoming external e-mail was down because they self-hosted their DNS & domain registration, so their MX records went poof when they cut themselves off from the internet by fucking up their BGP tables.

'tis from last season:
Reminds me of TDWTF
"It became this funny thing where they were placing it on various people's desks," Tarbox said. "That joke wore a little thin. It was put into the trash."
Then there are the fresh things on the roof:
Do not whip around a stack of envelopes - the middle ones may shoot out, as this driver has learned.

The main problem is that Amazon has devalued the book, altering the collective sense among the public of how much books are worth.
In general I'm happy to kick Amazon when I can but I'm calling bullshit on this one. Publishing houses chasing stupid trends and saturating the market with garbage did this.
prefers instead to condition its customers into thinking that hardbacks are grotesquely expensive
Because they fucking are. They're there for collectors or the foohishly impatient. The paperback edition easily outsells the hardcopy everytime. Readers learned a long time ago what gamers are learning now. Don't pre-order and don't buy day one.
In any case, not much is likely to change unless authors and publishers stand up to Amazon.
Authors yes. Most publishers can fuckoff and die in a ditch. Half my kindle reading list wouldn't exist if it weren't for amazon taking everything onto their platform.

No. I'm (edit: not) defending the modern business model of releasing broken content and never really fixing it, but those are two different things.

I feel bad for them but when you setup shop in someone else's yard you don't get to complain when they turn on sprinklers. That emergency services are setup on infrastructure that they aren't paying for and don't have a seamless backup for should frighten people.

Yes. Also there's additional problems with this argument that are pre-Jeffed to the garage.

The goal of the mission is to determine how much the impact alters the moonlet’s velocity in space
Um, last time I took a basic physics class, knowing the velocity and mass of the asteroid and the velocity and mass of the kinetic impactor, finding the final velocity is a trivial calculation. Well, if you have good aim and nothing breaks into multiple pieces. If the impact is off-center, it's going to impart some rotation to the object, but that's only slightly less trivial to calculate. So the mission really boils down to determining how good their aim is. And how strong the spacecraft and asteroid are.
-
@HardwareGeek sadly, they were out of spherical cows at the rocket store the day that NASA went.
-
@boomzilla I guess the "doesn't send debris flying in all directions" assumption is sort of a spherical cow simplification. How much that differs from reality falls under determining how strong the spacecraft and asteroid are. But other than that, it's basic Newtonian physics.
-
@HardwareGeek I think it also depends on how inelastic the collision is.

The moonlit is in orbit around an asteroid, which turns it into a 3-body problem. Which is every so slightly harder to calculate.

That's the orbital problem. For before/after collision speeds, it's less relevant.
-
@topspin Sure, but it seems intuitive to me anything close to an elastic collision just isn't going to happen. Even with a solid steel projectile and a mostly nickle-iron asteroid, which might otherwise have a pretty high coefficient of restitution, with that high an impact speed, a heck of a lot of kinetic energy is going to turn into thermal energy, probably completely melting, if not vaporizing, the projectile and melting at least the impact area of the asteroid. Thus, since (it seems likely to me) there's little chance of any significant rebound by the projectile, the goal becomes to minimize the amount of momentum and KE lost to debris flying in random directions and transfer as much as possible into the main body of the asteroid. How to design a projectile to best do that is outside my area of engineering expertise and probably depends on the composition of the asteroid (tough nickle-iron, brittle rocky, carbonaceous chondrite, icy (comet), or mixture), and that is probably, at best, an educated guess.
-
@HardwareGeek said in In other news today...:

The point is to do it for real when there's no hurry to do so (and no danger to us for trying), so that if we ever need to do this, we're not flying quite so much by the seat of our pants. Getting some hard data on what an actual collision does (i.e., how much does reality differ from the ideal) is useful.
More data points would be better, but you never get anywhere without collecting the first one.

What makes this particular amateur-ninja attack unusual, as amateur-ninja attacks go, is the choice of victims.

As this excerpt from the local police blotter shows, it took some time for help to arrive, which left 26 special operations soldiers renowned for their skill in night fighting “hunkered down in a hang[a]r wondering where help is.”(emphasis added)

Of course; I never said otherwise. It's just that we can have a pretty good idea of what will happen, anyway. Given that the projectile is much, much smaller that just about any asteroid that would be a potential target (because it would pose a significant threat), it's unlikely that the impact would have a major effect on the asteroid (e.g., fracturing it into multiple large pieces), and it also seems safe to assume the amount of debris (and momentum) flung in random directions is going to be very small compared to the total mass, so its influence will be small. So it should be possible to set upper and lower bounds on the amount of delta-v that will be transferred to the asteroid. The biggest uncertainty is how close to the center of mass the projectile will hit, and thus how much useful delta-v versus how much spinning is imparted.
But by all means, get real data when it's not urgent. Calculations and simulations are all well and good, but nothing beats hard experimental data.

Actually more like "throwing stuff and actuallly hitting something" (that's the "impactor" part).

@Zecc “kinetic impactor” is a common fancy name for a missile or bullet that does not carry any warhead. So closer to “shooting something”.

How well do they actually know the asteroid's mass and composition though? (Honest question)
Maybe the center of mass isn't even where they think it is.
-
@topspin said in In other news today...:

The axis of rotation of the asteroid goes through the centre of mass, and that can be determined by observation. The composition is estimated by what sort of reflectivity the surface has at various wavelengths, but is very much a guess.

But it seems that cut isn't enough for those behind REvil: it was recently disclosed that there's a secret backdoor coded into their product, which allows REvil to restore the encrypted files without the involvement of the affiliate.
Wasn't there a kerfluffle about someone hacking a government thing a bit ago, and the hackers backed down and issued some kind of press release that boiled down to "we try not to take down infrastructure because we don't want a visit from Seal Team 6"?
This sounds like a way to enforce that.

More excited about Valve and what they're up too truth be told. My gaming PC can't automatically update to windows 11 so it isnt on the cards there. The surface said some of my apps won't work so thats a no go. Laptop is going Linux asap. 11 appears to be something of a damp squid.
