Just this weekend I took Ryanair to court. I filed in the Irish small claims court for EUR25. I am disputing GBP200 that they are wrongfully failing to refund to me.
Here in the UK/EU I have access to low cost legal means of pursuing bad actors. Sure, I may easily lose my court case, but at least I will have had an opportunity. I doubt $25 is enough to even consider a civil case in the US, let alone cover the filing fees.
The Brooklyn Bridge was built using inferior wire. I can easily believe that the World Trade Center towers were not built to the standard claimed. In particular, reading the WTC 7 report from NIST even states that pretty clearly: failure of column 79 would result in destruction of the building. It was either architecturally a terrible design, or was not built to specification.
"This is also in spite of the substitution of inferior quality wire in the cabling supplied by the contractor J. Lloyd Haigh—by the time it was discovered, it was too late to replace the cabling that had already been constructed. Roebling determined that the poorer wire would leave the bridge four rather than six times as strong as necessary, so it was eventually allowed to stand, with the addition of 250 cables. Diagonal cables were installed from the towers to the deck, intended to stiffen the bridge. They turned out to be unnecessary, but were kept for their distinctive beauty." Source.
This article suggests that ECC should be used more than it is. Since yes, a single bit error won't matter at all to an MP3 or a moviefile, single bit errors can ruin JPEG files pretty easily, or corrupt a Word document. The point is you don't get to choose where the error will occur, so you have to assume it will happen in the worst possible place. There is a reason ZFS systems should have ECC memory.
But you must agree that a high velocity round from a sniper rifle would probably have the same effect as we saw on the video. Also, shooting at the upper stage makes it more likely to go bang as the fuel and lox are physically closer together and a shooter would have a better line of sight to the top of the rocket.
One of these bad boys, a PTRD-41 can shoot up to 1km, but of course a real sniper rifle can shoot up to 2km ranges and still be lethal. No idea how that translates into piercing the thin lightweight metal shell of a rocket fuel tank. Also, the rocket upper stage is a huge target; and missing wouldn't matter, just keep firing until you hit it.
I don't live in the US, are high powered rifles such as these readily available?
Ah, dude, the object flies over the rocket at exactly the time of the explosion. Sure, the object didn't hit it, but it may have released something that did!!!!
Why is everyone in denial about the object that obviously flies over the rocket from frame right to left at exactly the same time as the explosion. Even Musk states that they don't know what happened and that someone heard something hit the rocket. It could even have been a drone, or a deliberate act of sabotage, but *someone* has to look at the video in more detail and determine whether it's a real thing, or just a bug!!!!!
This device can be used to easily take out any computer on a target net with minimal risk to the operator.
Once the computer is down, other network plants have an opportunity to do things:
1) Spoof the target MAC and pretend to be that computer on the network.
2) Wait for the computer to be replaced, knowing that the subsequent SSH connection will present fresh key signatures and can be spoofed.
3) Track the failed computer to the disposal route but intercept it and scrape it for target data before disposal.
4) Ensure an employee is not at their desk for 1-2 days while a replacement PC is located for them. Use that time to intercept their network port, phone system, or general physical location.
Yes, again I agree, but it's really difficult because ultimately that disregard for one's own life can actually make the net situation worse. You read about drownings in the paper all the time. Often some bystander or one of the parent's tries to save a drowning child and either they both perish, or the child is saved and the adult dies. Yes, the adult was being extremely brave and made the ultimate sacrifice. But what if that adult had other children who are now without their parent? One could argue that the net loss in such a case is worse than if the drowning child had been left to die.
The extreme outcome of this way of thinking is absolute tragedy such as this, which sickens me to even think about. How could that "rescue team" live with themselves after letting that happen?
Where's the balance? I don't think I'm wise enough to know....
Thanks for the great post. When Dan Riccio said "just a hole filled with air" it cemented my opinion that he's completely full of crap.
None of these design decisions really make sense. The obvious solution was to properly shield, and/or redesign their "driver ledge" components. I bet it was decided that would be too costly, or maybe no one is at the the helm and the "group think" of the engineering group simply jumped the shark on this one...
Not to get sidetracked (I agree with your post) but "run into a burning building to save people" is more stupid than courage. If you do not have a full face mask and respirator then entering a burning building will most likely get you killed. The toxic fumes from a modern house fire will overpower you and you will collapse and die. The only exception would be if you are entering a building at a lower level than the fire, but even then, it is possible for the lower levels to be filled with smoke and fumes. Stay safe, and don't always act on what you once saw in a movie. Fire and smoke kills.
I get your point, but the problem is one of scale. A lot of the external battery packs that I've seen are pretty much overkill for daily use. They seem to be designed for those that really need extra battery capacity, so the size doesn't matter.
A lot of the complaints about phone thickness have to do with adding 1-2mm (5-10%) to the phone and getting maybe 1-2 hours (5-10%) of extra use out of the device. That's what a lot of people posting here are after.
"Digging keys out of a physical chip takes insane resources and skill."
I'm not trivializing the task, but don't let yourself become flummoxed by silicon. Any chip can be disassembled. The best example I can post was about the two Cambridge guys who sanded the top off a smart card chip, exposing the circuit. They then used a microscope and a flash lamp to turn individual transistors on and off. The basically told the circuit to read out the key for them.
"The problem is that they don't have a revenue model for selling what most business customers want: the same OS for 10+ years, with support for new hardware and up to date security patches."
Er, isn't the revenue model offering the same OS for 10+ years with support for new hardware? The money comes from the customers who pay for the software. Simple really. The cost of the software development scales with the number of customers, so the cost is amortized. What you do is price the OS based on the previous years sales figures, so what happens over time is if the number of users shrinks then the cost goes up, the company still makes bank on the ongoing development work, *and* useful feedback is provided to the users: over, say, a five year period everyone can see the price going up and start to plan accordingly.
Simply yanking the product from the market and forcing the customer to move on is actually a lose-lose proposition. But ultimately it must make Microsoft more money than being a sane and rational actor...
Wow, a troll mod for a fun little joke post about a bug flying across the video frame at the time of the explosion. There are some really butt hurt space nutters around here these days...sheesh!
Love it! My initial thought was that 250bar of H2 may start to stabilise copper hydride and the whole block would disintegrate. But I just thumbed through my copy of Barin and note that CuH is not listed. The Wikipedia page is actually pretty helpful, and I notice there that copper is stable in hydrogen all the way up to 50GPa, so absolutely no problems at 250bar.
Don't knock it: "oxygen-free copper" is a "thing" once you realise that as far as elements are concerned there's a bit of everything in everything (mum jokes aside). So it's perfectly possible to make a batch of copper with less oxygen than another batch, and there are purity grades that specifically address this. But the key point is whether oxygen in the copper changes the electrical characteristics in any meaningful way...and the general consensus is that it doesn't.
These comments only apply to dual fridge-freezer units, which are quite common:
My understanding is that two actual thermostats are required since the freezer needs to be at -20C and the fridge at 4C. If the ambient temperature goes between -20C and 4C then a single thermostat (typically located in the fridge) turns off and the compressor stops. But the freezer will now defrost, especially so if the ambient temperature is floating around 0C. Worst case would be weeks of temperatures between -5C and 0C where the feezer contents would freeze and thaw and freeze and thaw in random ways, and even worse, upon inspection in the spring time the food may appear safe and completely frozen: but potentially deadly.
The second thermostat ensures the compressor keeps driving to keep the freezer section cold. Of course this also requires two coolant circuits, or a way to throttle the flow of coolant between the fridge and freezer, all of which adds cost, which is why it's rarely done properly.
You're right then: the better approach is to have the thermostat on the freezer side and have the second thermostat control a damper. Damn...need more coffee:)

And the US legal system is fundamentally broken.

I stand corrected entirely. I scoped out launch complex 40 at the Cape and you are correct, the shot would have to be made from the ocean.
So there's a 2-3km exclusion zone around the launch site? And that perimeter is effectively patrolled?
But you must agree that a high velocity round from a sniper rifle would probably have the same effect as we saw on the video. Also, shooting at the upper stage makes it more likely to go bang as the fuel and lox are physically closer together and a shooter would have a better line of sight to the top of the rocket.

I think this one would be pretty good.
Really not thinking too hard.

Very fast indeed, but we know it must have fired: the rocket exploded!
What, you couldn't see the UFO flying from frame right to left and was overhead at exactly the time of the explosion? Go check the video...I'll wait.
