Machine learning really isn't that difficult. Context is also not difficult at all. Here is how you do it. First, you need to organize your data into categories. Then, you will need a size limited revolving heap to sort these categories. This alone will take care of the context problem as well as datapath indexing. Real learning comes in three layers. First layer is categorical, the second layer is relational (think of edge and cost), and the last layer is informational (real data). Learning on the informational layer doesn't translate to other layers, and vise versa. This is also true with human intelligence. Just because you can recite a mathematical formula doesn't mean you can use it. The relational layer deals with processing of the data. This is what real understanding comes from. Think of a dictionary. What is a dictionary realistically? It is a collection of words that are defined by other words. I would go a step further and call it a synapse map. It is a path way for human beings to utilize the data we obtained in informational layer. The current AI that we have are essentially weak and misguided attempts at mimicking of human behavior. However, many failed to realize what really drives these human behavior and make abstraction out of those preprogrammed functionalities.
It is a misconception thinking you are 10% opacity. This is because the meta material bends light depending on frequency. So you will experience a hue shift under the circumstance where not all frequency are covered. In simpler term, you'll appear to be bright red or bright violet due to that 10%. That effectively turns you into a gigantic painted target that screams "shoot me!"
now you tested those passwphrase using a dictionary attack and they failed. So you know for sure these are not the passphrase. They can then be removed from the brute force efforts so you don't test the same thing twice.
yet they don't have enough sense to contact RIM to have them submit the specs and code review for configuring government only blackberry servers that our government has full control of and enable the blackberries in government to use that server? RIM would jump on that opportunity for the most powerful man to serve as a walking billboard.
What more important things to do than write emails and call people?
Seriously, what do you think the president's job is? How do you think he keeps in contact with his cabinet and thus stay on top of domestic and world events? How do you think he visits other countries' leaders? By just showing up at their door steps?
Think of the president as a project manager, except on the grand scale, then, you will understand.
I am sure the previous presidents of the united states used cellphones and laptops. This is no different by the combination of the two. What exactly are those security experts hired for anyway? They are suppose to enable usage of tools while preserving security, not by telling their boss what he can't do. They are getting paid big bucks for resolving the headaches, not creating them. Any incompetent fool can suggest not to use a particular solution, the competent IT workers get things done without disrupting the service.
Agreed, the only advantage for using flash is so you have an embedded video player that can play a relevant clip. As far as interactivity goes, posting feedbacks/discussions can generally be done without the use of applets or flash and is the only thing that adds any value.
i'm sure i will be modded troll for this one, but Linux has its fair share of crapware. Case and point, gnome, orbit, kde, you want to talk about crapware that runs at the root level? How about xdm, several generations of sendmail, inetd, and a myrad of ftp daemons. Linux also has an issue where the crapware doesn't always exist in the form of an executable, but a library. Things like oracle more often than not requires you to revert back to a vulnerable version of certain libraries. Oh, and our lovely toolbars also work on linux in firefox. Face it, linux isn't the answer to solve the crapware problem by a long shot.
not at all, i too share the same belief. however, i think when blackhole consumes enough energy, it actually rips spacetime bringing a small piece of spacetime with it. This is why we see blackholes disappear in space. This is not in direct contradiction to laws of energy conservation as the total energy will remain the same, it's just we will no longer be able to be affected by the energy at that point in space in the specified time. At that point, warping in spacetime created by singularity's gravity recoils and the little piece of spacetime held by the singularity expands. The recoil and expansion in spacetime will counteract gravitational forces and the internal pressure of the singularity will push all matter and energy out. Thus, big bang.
Easy, user keys. During account creation, generate a unique user key and send it to the client creating the account and make the login associate to the user key only. This way, the user can carry their key in a usb drive when they move around, the client will simply be directed to encrypt the authentication attempt using the user key.
the following may increase security: 1) associated user name do not affect key generation. (this way the attacker has to guess the user name linked to the key) 2) key morphing scheme. (this will make "left behind" keys essentially useless, and also let authentication become a intrusion detection mechanism. This however can become a problem in the event of network failure or power failure, thus need a propose/confirm threeway handshake.)
Note this is a bit different than the current ssl scheme where the same public key can be used for many different users. This essentially requires the host site to maintain a key database along with their user accounts. It will stop brute force because it would be rather difficult to reproduce an unique key generated at unspecified time with unknown hardware in unknown conditions and isn't even sent during login attempt. The server can then simply set to ignore any traffic that doesn't conform to protocol specification.
If you want it to conform with the web standards we have right now, just generate a cert for each and every user. On the user end browser will treat it as a normal ssl connection. On the server end however, you grab the user name via public ssl, then switch to the unique user cert for the rest of your session including password with that particular user. If the user lacks proper cert, well, the server will just serve blank and give protocol error. This cannot be password brute forced.
On the same note, has anyone cracked the xbox 360 hardware security? The only thing i see so far is that XFPS device which uses a "man in the middle" attack to hijack the connection between a controller and the console itself.
"Find in Files" are inadequate in most the cases without proper indexing. It misses matching files very often and will take a long time crawling through those files when you try to match without indexing. Especially when the files are sufficiently big, the search algorithm just gives up after a certain point. Also, have you ever run into character conversion issues? Anything you write in unicode will not get searched well using the "Find in Files" option. Grep on the other hand is a very good tool in term of accuracy and search flexibility. Although, indexed search is a lot faster and will save you tons of time in long term. Note that I am not saying indexing is the be all end all answer, I am just pointing out that there are significant uses for such methods and curbing user habits is rather archaic.
Hold it, you are assuming people are going to search only by file name. However, the rest of us do search by content. How will you remember which file contains "int restriction_level = 1;" on a project with thousands of files and a class diagram that looks like spiderweb on steroids? Indexing is very useful in that aspect.
Anyone wondered what kind of health hazard this thing really is? powdered metal can getting into your lungs, skin, and digestive track during production. I wonder if that is partly the reason why they don't have a prototype yet.
Microtransaction isn't just about making a profit. It can also allow a new company/game to grab a sizable player base quickly. "How?" you may ask. Many of the microtransaction mmos I have played offers a standard set of content free to sign up and free to play. This allows players to demo the game play as well as some of the content. Further more, free account players may choose to play for free indefinitely. Granted, they may have a limited experience, but they also create communities that draws others in. A second aspect to microtransaction is that it helps those who need to lapse in payment. Say if you got to move to a new place and for couple months you are worrying about more important things like unpack and furnishing than being bothered to play a game. Well, in normal systems you either get hit by a bill which you didn't utilize the service or you go through a hassle to get the game company to stop billing you then start billing you later. The second option also carried the risk of having your account removed. In case of microtransaction, you decide what kind of service you want and what time you want it. So there really isn't a need of "buying in bulk". Those plus points however do not reflect on all microtransaction games. I think there are more good points for microtransaction, although it really depends on the implementation of it in game. Some companies are trying to innovate while some others are just plain greedy.
After RTFA, I think the Chinese people are voicing legitimate concerns, it is very typical of/. to skew the study. The great firewall of China is like our government's "Do not call" registry in here, and there're no exception cases. Instead of requiring each and every operator to filter unsavory things, phishing, spam, and defamation, it is done by the government. The government on the other hand also added a big list of speech it considers illegal, but it seems the participants of the study wasn't really focused on those. The Chinese people wants the government to be the guardian of morals and civility as well as being a reliable source of information on the net. That's what that 85% means. It has little to do with censors that quiets down political speech.
My question to you is "why do we have to choose between feeling good about being about solve something and feeling good about my character being rich/powerful?" Think about it, traps mechanisms and complex puzzles in the old days do but one thing, to protect a treasure of some kind. You don't just solve the puzzle to solve the puzzle, it would be a quest of some sort or promises of riches to motivate people to go explore that dungeon in the first place. You personally might be an exception of the case, but why would you reject the notion you would get experience or items for solving a puzzle?
That is partly the reason why i suggested a randomized puzzle generator. Take example when a puzzle get solved in a particular part of the dungeon, it automatically morphs to a different configuration as soon as the party solved it passes. What you also can have are instantiated puzzle rooms where lots and lots of people can go into a room but each party get their own generated puzzle. This way it doesn't hold the spot for anyone else. There are many great designs, but large businesses tend to just copy and reuse an existing working model instead of go out innovate new ones. Fortunately for us, Nintendo isn't one of those.
I beg the differ, why then are games like zelda or portal so popular? The way i see it, people do like puzzles. Usually people would enjoy easy to medium difficulty puzzles with the occasional hard puzzles that actually gives them a sense of accomplishment. Also, help guides on the net is an obstacle because when puzzles get hard all the time, people tend to just cheat and look online rather than figure them out. Overtime, this turns into an automatic habit which turns lots of games into lookup and grind since it is better to grind than not being able to solve the puzzle. This issue can be avoided by using a randomized puzzle generator. Another problem is on the game development's side. More often than not, the games we play doesn't provide the players with enough obvious clues. Puzzles need to make themselves visible and intrigue the players rather than stay hidden all the time. For example, in doom you have to collect three brightly color coded keys to advance. Sometimes these keys will be in a hidden area, but the players know they have to find those keys. The final issue in games are immediate rewards. People like to grind usually isn't because grinding in itself being enjoyable. If you take away the exp, money, or item gained from grinding, I imagine very few would grind. The problem with puzzle solving in most game is that there's very few rewards associated to it. And even if they do, the reward usually isn't appropriate for the feat performed. Thus, people end up skipping the puzzles and go for the easiest way to obtain reward. In the end, i think online games would be much more enjoyable if these problems are addressed.

Agreed. further more, how do they know the data they got is accurate? i mean wouldn't we consider everyone who got tracked as "newbie"s?
Sure there is.
for example, your dictionary has
12345678
password
helloworld
computer
now you tested those passwphrase using a dictionary attack and they failed. So you know for sure these are not the passphrase. They can then be removed from the brute force efforts so you don't test the same thing twice.

Yes, in fact Batman did it ages ago with his cape!!!

risking to be modded troll, i would like to say sure there is an unbreakable lock. An unbreakable lock is a lock that noone cares enough to break.
