Marvel's New Thor Will Be a Woman

It isn't like people in the US name their daughters Jeffery [sic]....

Apparently they do in the Game of Thrones universe.

Marvel's New Thor Will Be a Woman

infogulch Imagination? (588 comments)

Are we so unimaginative now that it's not possible to come up with and build new characters? Existing characters have to be completely substituted, just to piggyback on the established lore and history?

And for what? To satisfy some new gender-equality metric? Seriously, I know it would take time and effort, but surely you can come up with a compelling unique story for a woman without them having to be propped up by a different character's previous popularity.

Python Bumps Off Java As Top Learning Language

infogulch Re:another language shoved down your throat (415 comments)

If you didn't want to learn programming languages, why are you taking computer science courses?

If you're being force-fed anyways, I think python would be much easier to stomach than java for introductory courses. And it would be much easier to grade (if grading consisted of more than "did it output correctly") since introductory students aren't exactly known for their exceptional code organization and formatting skills.

So fuel cell cars are memristors? That actually sounds about right.

Kids With Operators Manual Alert Bank Officials: "We Hacked Your ATM"

infogulch Stop Assuming Appliances Can DropIn Without Config (378 comments)

From this to Highway Sign Hacking to that researcher that made a botnet of home routers with default config to ping the whole of ipv4, I really hope admins are getting the point that you can't just drop appliances in public places without adjusting the default configuration. What critical infrastructure is left out there just begging for someone with an operator's manual to wreck it, or even worse, exploit it? Can we get a wake-up call to the administrators of these appliances?

Kids With Operators Manual Alert Bank Officials: "We Hacked Your ATM"

infogulch Re:Too dangerous to keep digitally now? (378 comments)

With that sentiment, you'd never put *anything* online. This whole thing is just some asshat ATM admins leaving stuff in the *default configuration*. This is the equivalent of buying a home router and not changing the default password (though nowadays routers come with individualized passwords, but they didn't used to).

Not A Hoverboard, but Close (Video)

infogulch Re:Not an advertisement... but er, yes, yes it is (66 comments)

The benefits of a hoverboard over a skateboard include being a smoother ride, being able to navigate over rougher terrain, requiring less manual pushing, and, well, just straight up flying.

While Onewheel doesn't exactly fly, it does cover the other three benefits (and on manual pushing, it's even better than Marty's), so I think it's fair to call it the closest thing to hoverboards yet.

That's the whole story folks. The fact that he did something notable doesn't remove his right to privacy.

Another Possible Voynich Breakthrough

Schizophrenia is not orthogonal to intelligence.

Surely you meant "schizophrenia is orthogonal to intelligence", otherwise you're saying that all schizophrenics are geniuses.

Whatever Happened To the IPv4 Address Crisis?

infogulch Re:IPv6 has this tiny problem (574 comments)


"Hey Joe, what's your IP address?"
"I don't have one, I'm behind a NAT and firewall that I don't control."

Of the two problems, I find yours the lesser of two evils.

Oldest Known Star In the Universe Discovered

infogulch Re:Oldest star to date, but likely came from anoth (141 comments)

Larger apparent magnitude means dimmer because magnitude is on a log scale, similar to pH is a log scale with a negative sign. Brightness = 2.512^(-Magnitude)

HTML5 App For Panasonic TVs Rejected - JQuery Is a "Hack"

infogulch Re:Boycott (573 comments)

Oh come on, the comments already look and feel a lot more modern, even if they are missing a couple features (read: it's still in beta). And the green gradient everywhere is getting old anyways.

HTML5 App For Panasonic TVs Rejected - JQuery Is a "Hack"

infogulch Unqualified (573 comments)

I don't suppose it would help to tell the reviewer that if they don't even know what JQuery is they shouldn't be reviewing anything that has to do with any web technology. It's just a convenience and compatibility wrapper library. It sounds like the reviewer has never touched any programming outside of excel, and is completely unqualified to perform any type of technical review.

With HTTPS Everywhere, Is Firefox Now the Most Secure Mobile Browser?

infogulch Re:unnecessary bloat cruft (279 comments)

Nonsense. If you're browsing the web and following a bunch of links, you would have to long press the link to copy it, long press to paste it in the url bar, edit the url to add the S (this is mobile, so moving the cursor directly between the "p" and the ":" is non-trivial), and hit enter... for every link you follow.

You can't just click the link and edit the url after the page loaded because you've already given away the url path, url query, cookies, referrer, etc to anyone snooping your connection. And what if a site doesn't support https and instead redirects you to its' http variant? For some people they'd rather it fail to load than load insecurely. There are many reasons to use such an extension.

GPUs Keep Getting Faster, But Your Eyes Can't Tell

infogulch Re:Lets not forget (291 comments)

Exactly, the games themselves have been pared down to fewer objects because our older cards couldn't handle it. Now there are new cards and people expect games that can use that horsepower to be available instantly? Sounds unreasonable to me.

When your graphics card can handle 3x 4K monitors at 120Hz and 3D while playing a game with fully destructible and interactable environments (not this weak-ass pre-scripted 'destruction' they're hyping in BF4 & Ghosts) the size of new york city without breaking a sweat, the bank, or the power bill, THEN you can talk about the overabundance of gpu horsepower.

VLC Reaches 2.1

infogulch Re:Still sucks (127 comments)

Videos are meant to play forward, and codecs take advantage of this for compression. A common way to capitalize on this property of video is to use two different types of frames, usually named A and B frames.

A frames contain the complete data for that frame.
B frames refer to the previous frame and only have data on the changes that need to be made to the previous frame to make the current frame. (e.g. "move this section 2px to the right", "this little section has these completely new pixels...") **Note: B frames can be stacked.**

Why use B frames at all? They greatly improve compression. Think about shots in scenes where very little changes over the course of the shot, like a standoff in a western duel; there could be 10 full seconds where the only thing that changes in the shot is some tumbleweed blowing across the road. With B frames, it only has to store the tumbleweed on each frame along with some other very small changes, and there could be several hundred B frames in a row.

Playing forward is easy, just keep a copy of the current frame; if an A frame comes along, completely overwrite the current frame and display it; if it's a B frame, make the listed changes to the current frame and display it.

But if you're playing in reverse, what happens when you get a B frame? The player doesn't know what the "current" frame is since the current frame is built in forward order, so to do it correctly the player would have to walk back until it finds an A frame, then play all the B frame changes to it until it gets to the frame we want.

There are other complications to playing in reverse as well. For example, frames can have very different lengths. The length of each frame is recorded at the beginning of the frame, so to find the next frame you add the length of the current frame to the current position in the file. What about the previous frame? Where does it start? Since a frame could be any size and any type (A or B) you have to jump back the maximum frame length and search forward until you get some data that looks like the beginning of a frame.

It's not impossible, but playing highly compressed video in reverse (or stepping back frame by frame) can be very complex.
