Dunno. I had meant to also link it to the article, but I forgot.
I was thinking that it may not be a coincidence. What if, while developing the SHA256 algorithm, they needed an arbitrary starting point or seed, like deciding where to begin drawing a circle? And so, whoever made that choice chose the one that gave this hash for this string? And what if someone did something similar in the SHA3 algorithm? That would be cool to find.
But, I don't know how the SHA2 algorithms work, and there probably is not any arbitrary starting point or seed.
A friend of mine discovered and I verified the other day that BASE64(SHA256("password")) == XohImNooBHFR0OVvjcYpJ3NgPQ1qq73WKhHvch0VQtg=
Is that "ohImNooB" just a coincidence? If so, then it's quite the coincidence. Taking the SHA256 of a password and converting it to BASE64 is a fairly common way of storing and displaying a password on a system. To have the representation of the word "password", which is a very noobish password to choose, contain the string "ohImNooB". Quite the coincidence indeed.
Unless it's not a coincidence. Would that be possible?
In Maine, if you see a person's password for their email account on a post-it note, and subsequently use that password to log into that person's email account without their express permission, then that is considered a crime of the same class (I, II, A, B; not sure) as beating up a small child.
I use Google Reader a ton in my iPod Touch's Safari mobile browser, and that site does the same thing. It and other site that use this feature don't actually hide the URL bar permanently. Instead, the URL bar always acts like it's part of the top of the web page once the page is fully loaded and rendered (during loading and rendering, the bar displays, no matter what). So if you scroll down the page, the bar scrolls away. Scroll to the top of the page, and the bar scrolls into view.
With this feature, a site can ask the mobile Safari web browser to artificially simulate a scroll of the height of the bar. This is very nice, as it lets the web page have more assured screen space for its initial view. When you use a site like Google Reader a lot on your iPod Touch, it's nice to have this large initial view.
Instead of removing this feature, if something is to be done about the risk of a website using a visual trick against a user, I'd rather that a mark of some sort be placed on the status bar at the top, beside the clock, radio strength, battery charge, etc. This way, if a user sees a URL bar and that mark at the same time, then the URL bar he sees is obviously a fake.
The first thing to talk about is, Kinect was not actually hacked. Hacking would mean that someone got to our algorithms that sit inside of the Xbox and was able to actually use them, which hasn’t happened. Or, it means that you put a device between the sensor and the Xbox for means [sic] of cheating, which also has not happened. That’s what we call hacking, and that’s what we have put a ton of work and effort to make sure doesn’t actually occur.
What has happened is someone wrote an open-source driver for PCs that essentially opens the USB connection, which we didn’t protect, by design, and reads the inputs from the sensor.
Hacking means taking a (usually integrated circuit or code based) product that was designed for, built for, tested for, and meant for use A, and modifying it or its inputs or its outputs for use B. Cracking is bypassing a security system, by means of hacking, for the purpose of hacking or some other purpose.
By these definitions, the Kinect was hacked. If the internal Xbox algorithms had been found and used or if someone had augmented the Kinect to cheat in a game, then that would probably be bypassing security systems (I don't know the specific internals of the Xbox) and that would be cracking.
Does the light produce much in the ultra violet spectrum? I had always thought that seasonal affective disorder was partly due to the reduced amount of ultra violet light being received from the sun on your skin. UV helps your body produce or use vitamin D, right? I do still think that waking with light is an important step in the day. Also, I've been using f.lux the past few months, which reduces the color temperature of my computer screen at night (makes it less blue and more red), which has had a significant effect on me getting tired earlier at night. So even what kinds of colors your eyes sense can affect your cycle and therefore your health. In general, attempting to artificially create a sun in northern's daily lives through the winter months is probably a good thing.
Supplemental question: If there were clear evidence of a malicious cyber-security attack by a foreign government against our military, civilian government, electrical grid, financial systems, or other critical infrastructure, should the President have the authority to take control of or effectively shut down portions of the Internet to mitigate a crisis?
The results:
A clear majority of Americans (61%) say that the President should have the authority to take control of the Internet in the event of a malicious cyber-security attack.
Presidential authority to take control of Internet in a crisis:
Household income: Affluent consumers ($75K+) LEAST supportive of Presidential Internet takeover in event of crisis (56%)
Race: Blacks are much MORE supportive of Presidential Internet takeover (86%) than Whites (59%)
Gender: Women are more likely (67%) to support a Presidential Internet takeover than are men (55%).
I always thought the 88 miles per hour requirement explained this. To time travel with the Delorean, it needs to be traveling at 88 miles per hour with respect to the surrounding matter, or frame of reference. If this is a requirement of the time machine, then it's not a large leap to assume that the time machine travels in respect to the position of the surrounding matter, too.
Distance light travels in 126 microseconds: 23 miles, or 38 kilometers. That's fast.
TFA isn't detailed on what exactly takes 126 microseconds, calling it 'trading time,' 'trading speed,' 'latency,' and maybe how long it takes to process orders. I'm wondering, where are the computers that are doing the trading? Do they need to be positioned within a few miles of the stock exchange servers, with dedicated fiber optic lines between them? Because it sounds like that'd be necessary to make this kind of speed up in the stock exchange servers meaningful.
He made a battery in the woods, and that's cool. I hadn't realized that copper and iron were that easy to get without digging much. And, I can see how he could get at least some distance of copper wire. However, he did not tackle sensing the voltage that's turning on and off and communicating that to the user at the other end of the wire. At least not in this video. Does anyone have an idea of how to do that?
Anecdotal example: I heard about the feature that the iPod Touch 2nd generation performs an undo action in the Notes app when you shake it. So I tried it while sitting down, without having a cover on it. It slipped out of my hand, at an angle more horizontal than vertical, and fell 2 feet down to the thin carpet sitting over concrete. The glass cracked.
The Nike shoe system transmits step information over Bluetooth, I believe. My iPod Touch 2nd generation came with an app from Apple called "Nike + iPod" that uses Bluetooth. The app can be enabled in Settings > Nike + iPod > On. There may also be a related Bluetooth remote out there to control music playing ( >|| , + , - , |<< , >>| ).
At a university I attended, I noticed that, year after year, I would keep seeing the same ad-hoc name, across many different dorms on the same, big campus. The university had wireless in most of its academic buildings and some parts of the dorms, but most people in dorm rooms couldn't get it (we were encouraged to use the provided wired connection instead). Someone must have made an ad-hoc who knows how long ago (it was called "{university name} wireless", which is nothing like what the actual university's SSID was called), and people must have just kept connecting to the spreading and persisting ad-hoc name, hoping they'd get wireless internet access.
When I clicked TFA link, I immediately recognized the image from somewhere. I think it's nice to have references to where you may have seen this before, if just to assure you that you have not gone as crazy as you may fear.

Depends on your definition of 'worse'. In 2008, they recovered 2.44375% of their spending and in 2007 it was 2.45714%. Though, in 2008, they lost $15.609 million, and in 2007 they lost $20.484 million.

200 texts a day is 6,087.5 texts per month. If you have a Verizon Wireless plan called "Nationwide Talk", which does not include allotted texts but does charge you $0.20 per incoming or outgoing text, then that would cost $1,217.50 per month, or $14,610 per year. Huh.
