Submission + - Structural Engineer Destroys the Fallacies of Bridge Destruction (hackaday.com)

szczys writes: Suspension bridges like the Golden Gate Bridge and the Brooklyn Bridge are favorite victims for movie makers but are almost always shown to perform in violation of the laws of physics. Structural Engineer Alex Weinberg couldn't stay silent any longer. He covers how bridge collapses in several major films should have looked. The biggest offender? Christopher Nolan's The Dark Knight Rises.

Well, yes, the drive remains unlocked in sleep mode but locks if you hibernate. Someone with hardware that doesn't suck cloud easily resume from sleep, let the bios unlock the drive and then switch the hardware over to the PC of choice and copy off the decrypted data.

This is not a strike against the encrypting drives, it's a question of user training: the drive is locked in these situations and unlocked in those. If you want it locked, do this not that.

If there's any kind of farm in the neighborhood (aside from the gardening stores which refer to themselves as farms) then the closest you are to the city is the far edge of the suburban strip. Farms can't afford to operate on normal suburban land prices or pay the requisite property taxes. When suburbia expands, farms close and sell to developers.

Except there was no housing bubble in that area. What we paid was scarcely more than what that same house sold for 15-20 year earlier.

That wasn't a red flag for you? That at the same time other locations were doubling in value, the neighborhood you were considering was flat?

Yet they go for the 30 year mortgage because they can't afford the payment of a 20 year on the same house.

There's a word for those folks: suckers. If you can't afford a 15 year mortgage on a house, you can't afford the house. Buy smaller.

If you have the diligence and the right bent of mind, it can be smart to get a 30 year mortgage and regularly make extra payments to principal instead. That way you're not compelled to make a larger payment when you have a thin month or three. But if you can't -afford- to make the larger payment the bottom line is that the house is too much for you.

I do not count that in as part of our losses. You can challenge the validity of that rationale if you want

I believe I have. If you haven't figured every way in which a transaction impacts your financial standing then you don't know whether you've gained or lost money on the transaction, making any claims of gain or loss suspicious at best.

Comment Re:What exactly are you backing up? (Score 1) 118

we want to manage these backups centrally from a console

You don't want to do that, you only think you do. That needlessly creates a security problem by intentionally installing a remote control vector. What you want is a central notification system so that if a machine expected to back up does not, you find out about it and can send on the IT staff.

What i.r.id10t alludes to is also correct: figuring out how you can restore a machine to operation is step one. That determines what form the backups can be stored in which, in turn, determines what backup tools you can use. Linux machines can be restored by booting from a live CD, writing individual files back to disk and then running "grub install." Can Windows do that, or will you need to grab a full disk image of the C: drive every time you do a backup?

So basically you:

A) bought near the top of a housing bubble (which only escaped your notice if you were willfully blind to how badly overbought the market was)

B) bought at or past the border between suburban and rural where any kind of downturn would hit first and recover last (which can't have escaped your notice if there was a dairy farm in the neighborhood)

C) stayed only in for the part of the loan where the overwhelming majority of the mortgage payment was interest. You gained almost no equity from the mortgage payment just as if you'd paid rent. (30-year loans bad, 20 year and shorter loans good)

D) elect not to include in your calculation the payment of property taxes (loses you money) and the difference between pre-tax money spent on mortgage interest versus the post-tax money you would have spent on rent (gains you money)

So yeah, if you do all the important things wrong, you can lose money on a house.

Unless those 8 years were 2007-2015, you did something wrong. Like paying more than it was worth up front, failing to adequately investigate planned changes to the neighborhood or staying only 8 years of a 30 year loan (30 year loans are scams for the first 10 years -- very little of the payment goes to principal until you're under 20 years and since payments to principal are essentially payments to yourself, you have to consider them gains of ownership).

If you bought in '99 and sold in 2007, you doubled your money almost anywhere. The few places you didn't, it was pretty obvious in '99 that something was fishy.

Houses in my neighborhood are selling for 3 times as much as I bought mine for 15 years ago. And that's before you consider that the pre-tax money I've spent on mortgage interest in that 15 years is vastly lower than what I'd have spent on rent.

It's actually rather hard to lose money on a house purchase. You kinda have to be a financial numbskull.
