World of Tanks

Why is World of Tanks considered an MMO? I am told it is a series of 10 v 10 or 15 v 15 engagements. --Tarcil (talk) 00:55, 13 June 2014 (UTC)

I am a big player of this game. Keep in mind that while the normal public match is 15v15, there are also clans, and Clan Wars, which allow you to attack and defend land based upon a map of the U.S. Diplomacy and rivalry plays into it. There are also other modes, including team battles and historical battles. But yes, the general gist of the game is 15v15 for 15 minutes. I refuse to try to decipher what the actual definition of an MMO is, but I hope this will help. Justin15w (talk) 14:40, 13 June 2014 (UTC)

Simplest algorithm that cannot be reversed easily?

What is the most straightforward algorithm in cryptography (in real life or just for educational purposes) that cannot be reversed easily?OsmanRF34 (talk) 18:24, 13 June 2014 (UTC)

What do you mean by "cannot be reversed easily"? Some algorithms, like fingerprints, are not intended to be reversed. Others are meant to be decoded by a recipient. The complexity of the algorithm will tend to increase along with the difficulty of reversing it, so it's hard to pick a point and say "this is the most straightforward cipher that is hard to break". How hard is "hard"? —Noiratsi (talk) 19:26, 13 June 2014 (UTC)

I'm not sure if it's the kind of thing you're thinking of, but the Diffie–Hellman key exchange is a one-way function that formed the basis of a lot of modern cryptography. —Noiratsi (talk) 19:38, 13 June 2014 (UTC)

Is Cryptographic hash function what you're asking about? Katie R (talk) 19:47, 13 June 2014 (UTC)

Or Trapdoor function? --Phil Holmes (talk) 10:08, 14 June 2014 (UTC)

One of the conceptually most simple is prime factorization. Basic idea is, I pick two large prime numbers, p1, and p2. Then, finding m=p1*p2 is trivially easy. But, if only m is known, finding p1 and p2 can be quite computationally intensive. Going one way is easy, the other is hard, so these are also sometimes known as one-way functions.

Why would he say a corrupt file stopped the scan?

I use McAfee with Windows Vista and Internet Explorer 9. Several weeks ago my virus scan just stopped. It was at less than 1 percent and I couldn't restart it (though if I had waited, the scan went just fine the next day after I turned the computer back on). I went to tech support (by chat) and when I described the situation the person asked if I was seeing one file name stay on the screen. Yes, in fact, the file name is supposed to change many times a second. He said that was a corrupt file which would have to be removed. I knew not to do that myself because I didn't know what that file did. He sent me to a different tech support site (which started with chat but was changed to phone at some point) which would require me to pay, $70 US, or several times that for a year's subscription. But I got put on hold for a very long time and I had to rejoin the real world, so I hung up. The next day, I decided to try and see if I could do a scan and it completed with no problems identified. That was a month ago. All my weekly scans have completed with no problems identified.— Vchimpanzee · talk · contributions · 20:20, 13 June 2014 (UTC)

I think it more likely the index which it uses to find the files was corrupt, so it couldn't find the next file to scan. Apparently when that happens, rather than give a useful error, it just freezes. Of course, there could be other explanations, like that it ran out of memory. That's always what I suspect when a program just freezes up like that, because then it lacks the memory needed to do anything else, including displaying an error message. StuRat (talk) 23:14, 13 June 2014 (UTC)

What's likely going on here?

I have an iPhone 3GS. I have a Bytech charger you can plug into a car charger or a wall plug, and you plug a USB cable into it. The Bytech has a little red LED on it which is lighted when the thing is plugged into a power source. I have had two 30-pin-to-USB white cords break in the following way: charging my iPhone by connecting the white cords to the Bytech charger plugged into my car's charger port, the iPhone would periodically stop being in charge mode and then go back to being in charge mode (the red LED never went off; there would be stretches of time when it was all plugged in, the red LED on, but the phone not in charge mode). Again, the red LED never went off. Then eventually it exited charge mode and never went back into charge mode. I looked at the 30-pin side of the cord and could see burnt out pins (I haven't counted which pins are the burnt ones, but it's about 1/16" thick burned section just right of center when you look at the plug with the pins facing you and the (---) image on the plug facing up. Before the cords died, while they still led to spotty performance when plugged into the car, if I used them connected to the Bytech plugged into a wall plug inside, everything worked fine. As I said, this happened twice in exactly the same way. So I think this pretty definitively singles out the charger port in the car. But my wife's Samsung Galaxy S4 Active plugged into the same Bytech charger plugged into my car's charger port with a standard USB to micro USB cord has never had any problems. Then I got a non-Apple third party 30-pin-to-USB cord and tried connecting my iPhone to the car charger port and it again went temporarily to not charging while plugged in and the red LED showing it still had power, but I'm done sacrificing cords while the cord I have still works. Is my car charger port spiking high voltages to which 30-pin connecters are more susceptible to breakage than micro USBs? Will Apple devices go into non charge mode when the voltage goes too high? Peter Michner (talk) 21:54, 13 June 2014 (UTC)

I don't know about 3GS, but some newer iPhones have ways of detecting if they are plugged into an "official" charger, and that might be part of the issue, unless you are sure that this behavior only happens when charging in the car. See some discussion of off-brand chargers here , and links therein. SemanticMantis (talk) 16:55, 16 June 2014 (UTC)

Transfers between Xboxes

I have a Xbox original console (like this model) that has died on me, & I'm thinking of getting another one. But I was wondering if I did get a new one, could I transfer my save games etc from my old Xbox console to the new one ? Scotius (talk) 13:44, 14 June 2014 (UTC)

When I say that my Xbox has died on me, what I meant was when I've been playing a Xbox game, a DVD or a music CD even, either at the the moment the disc is inserted into the Xbox or at some point after, during playing the disc I start getting error messages like,
"Your Xbox cannot recognize this disc. Make sure it is an Xbox game, DVD movie, or audio CD. Also checkto see if the discis dirty or damaged. Remove the disc to continue."
Also,
"There is a problem with the disc you are using. It may be dirty or damaged."
Also,
"The DVD region of your DVD Playback Kit reciever is invalid. Remove the disc to continue."
When I've gotten these messages i've checked the discs to see if they where dirty or damaged (even when it's been a new game etc). But what I can't work out or understand is that i don't get these messages every time I try to play the same discs. Scotius (talk) 12:25, 15 June 2014 (UTC)

I'll be perfectly honest, I neither have, nor have, an original xbox, this is just what I could find. That said, it looks like you can set it up so that you can transfer files from xbox to pc and back by softmodding your xbox. So, if you were to do this to both boxes, you could transfer files from one to the pc to the other. Ill be perfectly honest, I'm not 100% sure that this will/would work, nor am I sure if you can get banned from xbox live, etc. etc. etc. So, try at your own risk - just a lead for you to consider. Anyways, here's a few sites with some info (you can find way more on Google): , , , . Hopefully this will be helpful - again, let me stress: I have no idea exactly what risk, or difficulty, is involved, so definitely research further before undertaking. Good Luck:-)Phoenixia1177 (talk) 14:00, 15 June 2014 (UTC)

Disk read errors are often caused by dirty or scratched lenses, though the messages always blame the discs. Have you tried giving it a shot of compressed air? Opening it up and gently swabbing it with a Q-tip and rubbing alcohol? Can't vouch for the Xbox, but it saved my PS2 and PS3. Third time on the PS3, I cleaned too firmly and ruined it. The Xbox laser beam is wider than the Blu-Ray one, so it shouldn't be quite as sensitive to small defects. But still, be careful.

No clue on the transfer. Hopefully you don't need it. InedibleHulk (talk) 12:25, June 16, 2014 (UTC)

Setting hostname in Linux

I have now transferred all my files from my old Fedora 17 hard disk to my new Fedora 20 hard disk. Everything went OK. I simply used cp -a to copy my entire home and photographs directories. I told cp to overwrite the profiles.ini file in the Mozilla FireFox directory, and I didn't have to overwrite anything in the Evolution directory. Now I can access my FireFox profile just like before, and all I needed to access my e-mail was to re-enter my account password, which Evolution helpfully stored in its keyring. But the hostname is still shown as an ugly numerical IP address. I typed hostname -b teletran-1 as root, and it set the hostname to "teletran-1" in the bash prompt. But after I rebooted, the hostname became the ugly numerical IP address again. How can I make my nice custom hostname stay? JIP | Talk 15:09, 14 June 2014 (UTC)

The man page for hostname(1) says "Note, that this is effective only until the next reboot. Edit /etc/hostname for permanent change." -- Finlay McWalterᚠTalk 15:18, 14 June 2014 (UTC)

Although that may not the the case on a Redhat-based system like Fedora (which I don't have to hand), as Redhat uses additional config files for net connections - see this for discussion about this (which was, and I guess still is, /etc/sysconfig/network). -- Finlay McWalterᚠTalk 15:29, 14 June 2014 (UTC)

Retrieve Windows product key

A relative's laptop recently died of motherboard failure. There are many other components still in good condition, including the Windows 7 installation on the still working hard disk. If I was to connect the hard drive by USB to another PC (running Windows or Linux) is it possible to use a software tool to retrieve the Windows product key? The original Certificate of Authenticity, that was on the bottom of the laptop, got destroyed/defaced by the same liquid that caused the motherboard to fail. Astronaut (talk) 10:36, 15 June 2014 (UTC)

Try ProduKey. It has command line options to retrieve keys from a slaved drive. --  Gadget850 10:54, 15 June 2014 (UTC)

If the laptop came with that version of Windows (as your mentioning the certificate of authenticity would suggest) then the Windows licence will surely be an OEM one. That means the product key will be be valid only for that make and model (strictly the licence itself only applies to the specific, now deceased, machine - Microsoft say the licence isn't transferable). So if you tried to boot off that disk on a substantively different machine, it would fail the Windows Genuine Advantage check. For retail licences (where you bought Windows 7 in a box by itself and installed it on a machine) then they seem to take a somewhat more liberal stance (some upgrades to the same machine present a Ship of Theseus problem for them). -- Finlay McWalterᚠTalk 11:18, 15 June 2014 (UTC)

Disk-spanning/external packages on NSIS installers?

Anyone know of a good plugin for NSIS which allows me to do disk-spanning (i.e. for large installers) or extract stuff from external files? I did manage to search for stuff like ExtractDLLEx and ZipDLL, but I'm not exactly sure on how to utilise it for an installer I'm cobbling up. Blake Gripling (talk) 08:15, 16 June 2014 (UTC)

Web slideshow or image gallery

I am tasked with displaying about 80 images on a webpage. The images are from a 19th-century book. Many but not all of the images are similar in size due to some cropping and landscape versus portrait orientation. I want the user to be able to click on an image and open another window or tab to view a higher resolution version of the image. I also want the user to be able to control the advancement of the images if they want to, for example via Next/Previous buttons. I have found some JavaScript and jQuery code for slideshows on the web, but they are not meeting my needs. The biggest problem is the variable size of the images, which makes the rest of the page jump around as the slides change. I found one that addresses that but doesn't include control buttons and positions the slideshow oddly on the page. My attempts to modify the code I've found have been unsuccessful, mostly because I don't really know JavaScript/jQuery. Any suggestions? My main goals are displaying the images in order with the ability to access a higher resolution version, and I am open to doing this in a different way instead of via a slideshow. I suppose I could just put each high resolution image on its own webpage and have users click through them in order but that seems pretty clunky. I thought of making a page of clickable thumbnail images, but it is hard to see from a thumbnail whether or not you are interested in viewing the full image. I would know how to code both of those options -- I know HTML, CSS, and a little JavaScript. Thanks for your help.--Dreamahighway (talk) 16:24, 16 June 2014 (UTC)

There are lots of web sites that allow you to build a gallery just like this, with no coding required. Seems far easier to me. I set one up at AOL for a wedding once. There is some concern that those images may be taken down at some point, though, when that web site goes under or just decides to delete old photos. So, be sure you make a backup copy of the web page. StuRat (talk)

Yes, I suppose that is true. But since this is for a work project, a digital exhibit about a set of rare books, ideally I'd like the image part to be embedded in the page along with the other information. Or at least to have the same look-and-feel as the rest of the project.--Dreamahighway (talk) 16:44, 16 June 2014 (UTC)

Put the slideshow inside a DIV which to which you give a fixed size; make sure that size is bigger than the largest image. That way the rest of the page won't reflow when the slideshow resizes itself. -- Finlay McWalterᚠTalk 17:15, 16 June 2014 (UTC)

I tried this but it isn't working.--Dreamahighway (talk) 17:31, 16 June 2014 (UTC)

Facebook notifications

I set up a Facebook account but don't really use it, due to privacy concerns. Now I keep getting emails telling me I have a "notification". I pick on the link in the email, but it doesn't take me to a notification, just the main page. How do I find my notifications ? StuRat (talk) 16:26, 16 June 2014 (UTC)

(I'm more of a Google+ person...but....) Click on the little picture of the Earth at the top-right of the menu bar. SteveBaker (talk) 16:40, 16 June 2014 (UTC)

Thanks, that worked. I sure hate links that promise to take you somewhere specific but then just dump you on the home page and expect you to do all the navigation. StuRat (talk) 05:18, 17 June 2014 (UTC)

And I hate systems that stick a blue-on-blue 30 pixel square picture of planet Earth on your menu bar and somehow expect you to realize that this means "Show me my notifications please"! SteveBaker (talk) 15:04, 17 June 2014 (UTC)

Yes, I hate icons, too. I've finally gotten used to the overlapping 0 and 1 for the on/off switch on many devices, but it's still meaningless to anyone who doesn't already know what it does. And that's really bad, not being able to find the on/off button. StuRat (talk) 02:21, 18 June 2014 (UTC)

Be careful of clicking on links in an e-mail unless you're absolutely sure of the e-mail's authenticity. Otherwise, you could be a victim of a phishing scam. A Quest For Knowledge (talk) 17:24, 17 June 2014 (UTC)

Android contacts

In the messenger app Telegram, I'm part of a group. There is this one person in that group whose number I don't have. Unlike WhatsApp, only phone numbers you have already saved are shown to you in Telegram. However, I would still like to save the person as a contact in my Android phone book and have a link between the contact and Telegram. Android does it automatically with people with numbers. Is this possible with contacts without numbers too? Otherwise I don't understand the purpose of saving contacts without numbers. There is the option "Only display contacts that have phone numbers" in the phone book settings, which indicates that contacts without numbers must be somehow useful. --2.245.121.139 (talk) 17:50, 16 June 2014 (UTC)

Can't contacts also have email addresses? If so, then seeing contacts without phone numbers is still useful because you can email them instead. Come to think of it - doesn't it keep Skype handles too? SteveBaker (talk) 19:27, 16 June 2014 (UTC)

4GB or 8GB Upgrade to use Mavericks?

Hey all. I'm currently using my old Macbook (5,1 - late 2008) and am interested in upgrading from 10.6.8 to the new (and free!) Mavericks. My book only has 2GB of RAM right now (which surprisingly has gotten me through a lot over the past...five~ years), and I've read that I'll be wanting at least 4GB of RAM before I make the update. I know the 5,1 officially only supports 4GB but can actually utilize up to 8GB. The 2GB has been fine up to this point (I built my own PC for games) and I'm not sure if the extra 4GB (and $50+) is worth it, though I'm cautious about how much RAM Mavericks will need to actually feel like an upgrade.

Has anyone upgraded? Any advice would be appreciated! Thanks! 74.69.117.101 (talk) 19:06, 16 June 2014 (UTC)

I have 4GB and it works fine if you are only doing a few things at once. But I usally have a web brower, mail, Excel, TeX, Xcode, a few terminals and XQuartz and it takes a while to change between them (longer than when I used Snow Leopard). Also it takes longer to boot than with Snow Leopard. I'm not sure whether more RAM would help, but it wouldn't hurt. I've not had any problem playing games on it though. Dja1979 (talk) 19:58, 16 June 2014 (UTC)

Dja1979, if any of your alleged performance regressions have factual, quantitative data to back them up, please consider submitting a bug-report at the Developer portal. In general, new versions of the operating system are designed and tested to meet or exceed the performance of prior versions. Nimur (talk) 00:46, 17 June 2014 (UTC)

iDevice connectivity

I have several iPods/iPads/iPhones and now a MacBook Pro and am going to be in an area with metered and slow internet doing some science ed stuff.

IP Address

When I edit Misplaced Pages, and when I type "what is my IP address" into Google, I get a response in the form:

2601:x:xxxx:xxx:xxxx:xxxx:xxxx:xxxx

But when I use whatsmyip.org and other IP address finders, I get a response in the form:

73.xx.xx.xxx

Why do I have two IP addresses? — Preceding unsigned comment added by 2601:7:1980:777:5DEE:90A9:1180:F1A9 (talk) 07:41, 17 June 2014 (UTC)

The latter is an IPv4 address, the former an IPv6 address. IPv4 is the original version from the first public internet, which is suffering from address shortage, so the powers-that-be are moving us onto IPv6. CS Miller (talk) 09:53, 17 June 2014 (UTC)

And you'll notice that if you don't sign in with an account name, Misplaced Pages displays your IP address in the signature line of your posts here...and, interestingly, it uses the IPv6 version. The deal with IPv6 is that it is only slowly being adopted. If you have IPv6 (as you evidently do) then old IPv4 services don't work. For that reason, your Internet Service Provider (ISP) is providing you with an IPv4 address to go alongside the IPv6 address during this transition period. Evidently (and ironically!) the whatsmyip.org site is one of the many that has yet to transition.

There is actually an alarming problem here - the world is running out of IPv4 addresses, and when that happens, we can't hand out any more and some people won't be able to access those old IPv4 web sites and other services. You'd think that web sites and email services and such would be working hard to switch to IPv6 - but they aren't. This is likely to reach a crisis point if those sites don't take notice of the problem soon.

delete photo from net

Abhinand1234 (talk) 13:38, 17 June 2014 (UTC)how to delete a unwanted photo of us from website or blog -

If you think they will listen you can ask the person who runs the blog to remove it. There are a few situation where you have legal options, such as if you own the rights to the image and you didn't give them permission to use it, but we can't give legal advice. If you think they will object to removing it then you should be aware of the Streisand effect, which could just make things worse. Katie R (talk) 13:51, 17 June 2014 (UTC)

Of course the image may well stick around in Google's image cache for a considerable time - and you have no control of the number of people who already copied it and might re-post it. Also, people may be accessing cached copies of it for a while yet. Then there is http://archive.org/web/ - which periodically archives the entire "visible" Internet and keeps it forever - so people may be able to find the photo just by looking through old archives of the website/blog.

Bottom line is that being 100% sure that the photo is truly and completely gone is flat out impossible. So don't ever put stuff online that you don't want popping up weeks, months, years or decades from now - don't post anything you don't want your parent/significant-other/boss/kids to see (even if you don't have a significant-other, boss or kid yet!).

Further Fedora questions

I have now taken the new computer my company gave me into use. I have managed to copy all my old Fedora 17 files to the new Fedora 20 system without problem. But I have some questions:

• As the computer only has two hard disk bays, and both of them are in use (one for Windows 8, the other for Fedora 20), I put my old Fedora 17 disk in a USB enclosure. The computer recognises it when it's the only USB disk plugged in, but not when there's any other USB disk plugged in (I have two more, which I use for backups). This happens even if they are not powered on. Why?
• When the computer recognises the above-mentioned disk, and I turn it on, Fedora tries to be helpful and automatically mounts it and displays its contents in a file browser window. I'd rather want to manage mounting file systems manually. How can I turn this automatic mounting off?
• I have a Creative Zen Vision W device which I use for storing photographs while on the go without access to computers. Fedora 17 used to be able to mount it as an MTP device, but Fedora 20 isn't. All I get is an error message saying the MTP device couldn't be mounted. I did some googling and found numerous bug reports about MTP not working in Fedora 20. Does it work? Can I do something to fix it?
• I was able to install Xine and libdvdcss with yum. I remember I also need xine-lib-extras-nonfree, but no such package exists for Fedora 20. I found something called "xine-lib-extras-freeworld", but when I tried to install it, I was told Xine was already installed. Do I need this? Are Xine and libdvdcss all I need to view commercial DVD content, which I bought fully legally, on Fedora 20 Linux?

Companies using pre-computer technology

(1) Which notable companies are not using computers in 2014?

—Wavelength (talk) 19:27, 17 June 2014 (UTC) and 22:24, 17 June 2014 (UTC)

I doubt there were any notable companies in 1994 that didn't use any computers, let alone 2014. Unless the ONLY thing they are notable for is not using computers, they're so cheap and ubiquitous, even companies in the poorest nations would have access to computers. What does "not using computers" mean anyway? There's no computers at the head office? They don't use online banking? They manually file their tax returns? They manually write out their employee's pay slips? I know people "used" to do this kind of stuff in the past, (I work for a bank and it completely floors me that banks used to keep hand written account records!) but it's SO much more efficient to use computers for the support and operations, even of companies that seemingly have nothing to do with computers, I doubt very much there are any medium to large organizations that use no computers at all. Vespine (talk) 22:45, 17 June 2014 (UTC)

Best I can think of is the Kremlin, but I doubt the have eliminated all computers. Even many Amish use some levle of computer technology. --  Gadget850 23:23, 17 June 2014 (UTC)

As for #2, I would expect pretty much every company to use both computers and land mail, land line phones, and paper files. In my experience, email, cell phones, and electronic files just aren't as reliable as the old fashioned versions, so keeping the old technology around makes sense.

Related to #1, a company that recently had a security breach and had many of their electronic credit card transactions stolen has gone back to the old credit card sliders to make carbon copies, at least until they can figure out a way to do it electronically in a secure manner. I forget which company it was (maybe Target) ? StuRat (talk) 02:09, 18 June 2014 (UTC)

Hexadecimal

I'm interested in learning more about the hexadecimal numeral system, how to use it, and some basic conversion examples to get me started. I already know that it is base 16, and that in addition to the numerals 1–9, there is also A–F — each representing its own distinct value (i.e. "A" in hexadecimal is equal to "10" in decimal, "B" = "11", "C" = "12"). And after the first "F", it resets to 11, 12, 13, and so on, until it returns to the alphabetized six values representing 10-15 (as in the basic decimal system. Then it follows up with an example. It reads as follows:

I can't possibly be the only person who finds this part confusing. As someone who knows virtually nothing about hexadecimal, that example does not help to educate me about converting from the standard base 10 numeral system. It just presents an equation using conversions the reader is presumed to know. I think the lead section should be partially revised, so as to give a better introduction to the topic for the unenlightened masses (i.e. myself). Kurtis 23:35, 17 June 2014 (UTC)

Um, you've copied the section from the article without the formatting, which is even more confusing. It actually says:

For example, the hexadecimal number 2AF3 is equal, in decimal, to (2₁₆ × 16) + (A₁₆ × 16) + (F₁₆ × 16) + (3₁₆ × 16),
(2 × 4096) + (10 × 256) + (15 × 16) + (3 × 1), or 10995.

I'd agree that it could probably be better explained though. AndyTheGrump (talk) 23:49, 17 June 2014 (UTC)

Looking into this further, the article used to read

For example, the hexadecimal number 2AF3 is equal, in decimal, to (2 × 16) + (10 × 16) + (15 × 16) + (3 × 16), or 10995.

I'm not sure that this wasn't less confusing... AndyTheGrump (talk) 00:04, 18 June 2014 (UTC)

• Oh... sorry about the formatting error. Forgot that it used subscripted numbers as well. But thanks for correcting me. Hopefully we can find some better way to represent hexadecimal in action (i.e. proper conversion from base 10). Kurtis 01:08, 18 June 2014 (UTC)

It might help to start at the small digits, rather than the large digits, as the math is simpler for them. Also, using the subscript "HEX" instead of "16" might make it clearer. StuRat (talk) 02:13, 18 June 2014 (UTC)

Adding memory to HP 250 G2

I have an HP 250 G2 with 4GB of memory. I bought an additional 4GB and would like to install it. I was unable to find any information on how to do that on the HP web site, so I looked on Google and YouTube for videos or instructions, also without success. There are many videos showing how to work with other HP laptops, but the internals of the HP 250 are different and it's not clear how to proceed. Ma_chups 00:18, 18 June 2014 (UTC)

Maybe this video? -- BenRG (talk) 01:54, 18 June 2014 (UTC)
