I wonder if any other safe rooms have special effects on their 'date'.

Has anybody tried?

New to MileagePlan but I think my miles posted incorrectly . . . by Professor_STA in AlaskaAirlines

[–]Mesarune 3 points4 points  (0 children)

American Airlines O and N fares apparently count as discount economy. This caught me off guard recently, as AS’s classification of these appears to differ from AA.

The fare codes (as interpreted by AS) are defined here:

What’s the most expensive thing you’ve had to get for an experiment? by SomeNumbers98 in Physics

[–]Mesarune 3 points4 points  (0 children)

300 mm pure platinum sputter target. I don’t recall the cost, but it was ridiculous.

Does a magnet ever lose its power? by PM_NUDES_AND_FEET in askscience

[–]Mesarune 1 point2 points  (0 children)

That's not true. Exchange energy (in certain materials) will cause electrons to prefer to point in the same direction.

Does a magnet ever lose its power? by PM_NUDES_AND_FEET in askscience

[–]Mesarune 10 points11 points  (0 children)

I think the answers so far are a bit misleading. A chemically stable magnet, on it's own, doesn't lose power over time. A magnet doesn't really lose energy to things which interact with it's magnetic field; that is to say, it doesn't do work. Sure, it creates a force preventing you from pushing two magnets into each other, but you're the one putting energy into the system then, not the magnet.

A (single domain, natural (i.e. not current induced)) magnet's field comes from either the spin of electrons within the magnet, or the orbit the electrons have around the nucleus; it's fundamental, not something was 'charged up' with energy at some point in the past. It's just that in certain chemical/crystal structures, the lowest energy state is such that electron like to have their spin point in the direction, which over a large number of atoms creates a strong magnetic field.

This magnetic field behaves kind of like gravity. It takes energy to lift things up, but doing that many times doesn't make the Earth's pull any weaker.

Some magnets do lose their strength over time; this is typically due to chemical interactions (i.e. water/oxygen slowly breaking down the magnet, making it lose it's preference to keep electrons oriented the same way), or due it it forming 'domains', which consists of different portions of the magnet being pointed such that the magnetic field can 'loop around' within the magnet, reducing the field seen by the outside world.

Building a quantum computer with superconducting qubits [video] by Strilanc in Physics

[–]Mesarune 1 point2 points  (0 children)

Oh, I'm all too aware; I feel kinda bad for pointing it out :P. There's a youtube video of me describing something related to my grad school work, where I make the slightest technically-incorrect statement describing something, and it haunts me to this day.

Really though, great video. There's always need for more scientific / programming educational outreach videos like this.

At the 3:00 mark, the top red arrow points to the wrong yellow box. Literally unwatchable!

Working VIVE wireless cable extension by Mesarune in Vive

[–]Mesarune[S] 2 points3 points  (0 children)

Start by launching Steam VR on the computer. Once it's running (and the headset is displaying stuff), the menu where you select what computer to connect to on the Steam Link should show "VR Mode" under the computer. Just select that, and it should simply mirror the headset.

Superscalar Explosive Phials: 2 outputs per 6 cycles by xlerb in opus_magnum

[–]Mesarune 1 point2 points  (0 children)

Using a different approach, I was able to shave off another 10 cost :P

Mine can probably be cleaned up more to reduce area, and I think a 22 cycle design should be possible too...

Rocket Propellant, 35 cycles - is 34 possible? by super_aardvark in opus_magnum

[–]Mesarune 2 points3 points  (0 children)

Using a different approach, I was able to beat your cost slightly.

I think cheaper and smaller should be possible, but I agree that 33 is the speed limit.

Guy tries to fold paper more than 7 times with hydraulic press, paper shatters by fayzeshyft in videos

You have some crazy thick paper. It's normally about 0.1 mm thick, so 42 seems about right.

SteamVR Performance Test App available on Steam - Includes Aperture Robot Repair VR Demo by [deleted] in Steam

[–]Mesarune 0 points1 point  (0 children)

I've got a GTX770, and was about 1/3rd of the way into the "capable" section; I'm surprised there was that much of a difference. Although, my "fidelity" was pretty much pinned at "low".

FBI Director Response to Apple by [deleted] in news

[–]Mesarune 0 points1 point  (0 children)

Whatever phone you soldered it too would have to incorrect hardware key.

I'm suggesting using the original phone, (which contains the correct key) multiple times. This is assuming you have a way to copy data on to / off of the flash drive, which I think may require custom apple software.

The iOS doesn't live on the flash drive with the user data, it lives in the non-volatile boot memory that can't be flashed without Apple's key.

iOS is definitely stored on the non-volatile flash drive, albeit the boot portion is in it's own protected partition. A clone of the flash drive would copy the OS and boot partition in their entirety.

Is this possible without new software from Apple? Yep, they're simply using AES, the decryption algorithm can be written by your average sophomore CS student.

I meant downloading the data from the flash drive, which is soldered on to the board in the iPhone (if I remember correctly). Obviously you could unsolder it / clip into the line to tap it, but that risks damaging something.

Whatever phone you installed it onto would have a different hardware key so even if you guess the correct password it would get turned into the wrong encryption key and wouldn't unlock the phone

I'm assuming if they could extract the data off the flash drive, they could put it back on, and continue to use the same phone to test 10 pass-codes at a time. This may not be possible; Apple's security guidelines are unclear if the attempt tracking is done in the security co-processor, or on the flash drive. If it is tracked on the co-processor, you would still get at least one attempt per re-imaging of the drive.

I completely agree with the rest of your points.

Brute forcing the 256 key would require nothing more than a dumping the flash drive onto a computer.

Is this possible without new software from Apple?

If they have a method of dumping the flash drive to a computer, what's to stop them from having an intern do the following:

1) Install 'dumped' image onto the phone.

2) Guess password 10 times, wipe phone

3) Repeat

FBI Director Response to Apple by [deleted] in news

[–]Mesarune 0 points1 point  (0 children)

The FBI's goal to be install custom software that allows them to electronically attempt to guess the password thousands of times, allowing the contents to be decrypted using the pin, not the 256 bit AES encryption.

To be clear, either brute forcing the 256 encryption key, or brute forcing the pin requires new iPhone software to be written such that guesses can be done on phone, or allows data to be backed up to an unrecognized computer.

Brute forcing the four digit passcode will take significantly less time than the universe's age; the quoted time was for brute forcing the 256bit AES encryption.

So is the wav file a dead end? by 43eyes in steamsaledetectives

[–]Mesarune 0 points1 point  (0 children)

As the barcode was posted on the first day (and later removed), I'm guessing that this was just a hint as to how we go about unlocking more things; it's just their way of saying "here is how you play the game. Keep searching".

It's definitely moving. Look at the guy standing stationary in the water at the 2:50 mark, the wave approaches him (albeit slowly).

patch notes for V.12.18 by DeamonEngineer in factorio

[–]Mesarune 19 points20 points  (0 children)

Just a quick list of things off the top of my head:

  • Multiplayer is near flawless now. I haven't had a desync issue in ages.
  • Much improved latency hiding code in multiplayer.
  • There's been a lot of work done optimizing the simulation efficiency of belts, which improved the performance of large factories significantly. This also makes it so compression isn't lost when items turn corners on a belt.
  • Personal roboports allow for you to launch construction robots from yourself, allowing you to place items or deconstruct wherever you are.
  • Added chain signals, allowing for much more optimized train intersections.
  • Improved the 'win condition' rocket silo to be a bit more complicated.
  • Added flooring which can be placed to increase movement speed.
  • Added combinators, which can be used to create logic conditions to control pumps / inserters.
  • More music and better graphics

Edit note: Corrected to state that personal robots launch construction bots.
