• Preventing item duplication?

  - by PuppyKevin

  For my game, there's two types of items - stackable, and nonstackable. Nonstackable items get assigned a unique ID that stays with it forever. A character ID is assosicated with the item, as is a state (CHANGED, UNCHANGED, NEW, REMOVED). The character ID and state is used for item saving purposes. Stackable items have one unique ID, as in the entire stack has one unique ID. For example: 5 Potions (stacked ontop of each other) has one unique ID. When dropping a nonstackable item, the state gets set to REMOVED, and the unique ID and state don't change. If picked up by another player, the state gets set to NEW, and the character ID gets changed to the new character's ID. When dropping all items in a stack of stackable items (for example, 5 potions out of 5) - it behaves just like a nonstackable item. When dropping some of a stack of stackable items (for example, 3 potions out of 5)... I really have no clue what to do. The 3 dropped potions have the state of REMOVED, but the same unique ID and character ID. If another player picks it up, it has no choice but to obtain a new unique ID, and its state gets changed to NEW and its character ID to the new one. If the dropping player picks it back up, they'd just be readded to the stack. There's two issues with that though. 1. If the player who dropped the 3 potions picks it back up, there's no way to tell if they legitimately dropped the items, or if they're duped items. 2. If another player picks up the 3 potions (assuming they're duped), there's no way to know if they're duped or not. My question is: How can I create a system that detects duplicated items for both nonstackable and stackable items?

• How can I pass an external instance to the constructor of an object that's being created using the default XNA XML content loader?

  - by Michael

  I'm trying to understand how to use the XNA XML content importer to instantiate non-trivial objects that are more than a collection of basic properties (e.g., a class that inherits from DrawableGameObject or GameObject and requires other things to be passed into its constructor). Is it possible to pass existing external instances (e.g., an instance of the current Game) to the constructor of an object that's being created using the default XNA XML content loader? For example, imagine that I have the following class, inheriting from DrawableGameComponent: public class Character : DrawableGameComponent { public string Name { get; set; } public Character(Game game) : base(game) { } public override void Update(GameTime gameTime) { } public override void Draw(GameTime gameTime) { } } If I had a simple class that did not need other parameters in its constructor (i.e., the Game instance), then I could simply use this XML: <XnaContent> <Asset Type="MyNamespace.Character"> <Name>John Doe</Name> </Asset> </XnaContent> ...and then create an instance of Character using this code: var character = Content.Load<Character>("MyXmlAssetName"); But that won't work because I need to pass the need to pass the Game into the constructor. What's the best way to handle this situation? Is there a way to pass in things like the current Game using the default XNA XML content loader? Do I need to write my own XML loader? (If so, how?) Is there a better object-oriented design that I should be using for my classes? Note: Although I used Game in this example, I'm really just asking how to pass any type of existing instance to my constructors. (For example, I'm using the Farseer Physics Engine, and some of my classes also need a reference to the Farseer World object too.) Thanks in advance.

• Moving characters on a grid [on hold]

  - by madmax1

  i am developing my first game with C++. My game uses a grid of rectangles. I have a class Board which manages the grid as a whole, initializes the terrain, places/removes characters, etc. It has a 2D vector of a class Field, which handles the Structure of the field, contained Objects, Characters, etc. Field again contains a vector of class Character, which are positioned on the field. Now i want to implement the functionality to move a character on the board, however dont know which is best practice to do so. Should i implement a moveCharacter(character, offset) function in Board, make it search for the character and move it? Or should i implement a function move(offset) in Character? This sure would be nicest, however makes characters necessary to know the board they are on, or the field which in turn knows the board. On the one hand i feel like i should avoid inclusion between classes as much as possible e.g. to increase portability of classes for different projects, on the other hand i think the character.move() functionality is most comfortable for further development. Im pretty new to "bigger" C++ projects and these kind of design questions pop up more and more often lately and i have troubles deciding. Thanks a lot for any advice!

• How do you handle animations that are for transitioning between states?

  - by yaj786

  How does one usually handle animations that are for going between a game object's states? For example, imagine a very simple game in which a character can only crouch or stand normally. Currently, I use a custom Animation class like this: class Animation{ int numFrames; int curFrame; Bitmap spriteSheet; //... various functions for pausing, returning frame, etc. } and an example Character class class Character{ int state; Animation standAni; Animation crouchAni; //... etc, etc. } Thus, I use the state of the character to draw the necessary animation. if(state == STATE_STAND) draw(standAni.updateFrame()); else if(state == STATE_CROUCH) draw(crouchAni.updateFrame()); Now I've come to the point where I want to draw "in-between" animations, because right now the character will just jump immediately into a crouch instead of bending down. What is a good way to handle this? And if the way that I handle storing Animations in the Character class is not a good way, what is? I thought of creating states like STATE_STANDING_TO_CROUCHING but I feel like that may get messy fast.

• Make Gameobject Stand On Surface Facing Certain Direction

  - by Julian

  I want to make a biped character stand on any surface I click on. Surfaces have up vectors of any of positive or negative X,Y,Z. So imagine a cube with each face being a gameobject whose up vector pointing directly away from the cube. If my character is facing "forward" and I click on a surface which is to the left or right of me ( left or right walls), I want my character to now be standing on that surface but still be facing in the direction he initially was. If I click on a wall which is in the forward path of my character i want him to now be standing on that surface and his forward to now be what was once "up" relative to my character. Here is the code I am working with now. void Update() { if (Input.GetMouseButtonUp (0)) { RaycastHit hit; var ray = Camera.main.ScreenPointToRay(Input.mousePosition); if (Physics.Raycast(ray, out hit)) { Vector3 upVectBefore = transform.up; Vector3 forwardVectBefore = transform.forward; Quaternion rotationVectBefore = transform.rotation; Vector3 hitPosition = hit.transform.position; transform.position = hitPosition; float lookDifference = Vector3.Distance(hit.transform.up, forwardVectBefore); if(Vector3.Distance(hit.transform.up, upVectBefore) < .23) //Same normal { transform.rotation = rotationVectBefore; } else if(lookDifference > 1.412 && lookDifference <= 1.70607) //side wall { transform.up = hit.transform.up; transform.forward = forwardVectBefore; } else //head on wall { transform.up = hit.transform.up; transform.forward = upVectBefore; } } } } The first case "Same normal" works fine, however the other two do not work as I would like them to. Sometimes my character is laying down on the surface or on the wrong side of the surface. Does anyone know nice way of solving this problem?

• What is meant by "no password set" for root account (and otthers)?

  - by MMA

  Several years back, we were more accustomed to changing to the root account using the su command. First, we switched to the root account, and then executed those root commands. Now we are more accustomed to using the sudo command. But we know that the root account is there. We can readily find the home directory of user root. $ ls -ld /root/ drwx------ 18 root root 4096 Oct 22 17:21 /root/ Now my point is, it is stated that "the root password in Ubuntu is left unset". Please see the answers to this question. Most of the answers have something to this effect in the first paragraph. One or two answers further state that "the account is left disabled". Now my (primary) questions are, What is meant by an unset password? Is it blank? Is it null? Or something else more cryptic? How does the account becomes enabled once I set password for it? (sudo password root) In order get a better understanding, I checked the /etc/shadow file. Since I have already set a password for the root account, I can no longer see what is there (encrypted password). So, I created another account and left it disabled. The corresponding entry in the /etc/shadow file is, testpassword:!:16020:0:99999:7::: Now perhaps my above queries need to be changed to, what does an ! in password field mean? Other encrypted passwords are those very long cryptic strings. How come this encrypted form is only one character long? And does an account become disabled if I put an ! in the (encrypted) password field?

• F5 Networks iRule/Tcl - Escaping UNICODE 6-character escape sequences so they are processed as and r

  - by openid.malcolmgin.com

  We are trying to get an F5 BIG-IP LTM iRule working properly with SharePoint 2007 in an SSL termination role. This architecture offloads all of the SSL processing to the F5 and the F5 forwards interactive requests/responses to the SharePoint front end servers via HTTP only (over a secure network). For the purposes of this discussion, iRules are parsed by a Tcl interpretation engine on the F5 Networks BIG-IP device. As such, the F5 does two things to traffic passing through it: Redirects any request to port 80 (HTTP) to port 443 (HTTPS) through HTTP 302 redirects and URL rewriting. Rewrites any response to the browser to selectively rewrite URLs embedded within the HTML so that they go to port 443 (HTTPS). This prevents the 302 redirects from breaking DHTML generated by SharePoint. We've got part 1 working fine. The main problem with part 2 is that in the response rewrite because of XML namespaces and other similar issues, not ALL matches for "http:" can be changed to "https:". Some have to remain "http:". Additionally, some of the "http:" URLs are difficult in that they live in SharePoint-generated JavaScript and their slashes (i.e. "/") are actually represented in the HTML by the UNICODE 6-character string, "\u002f". For example, in the case of these tricky ones, the literal string in the outgoing HTML is: http:\u002f\u002fservername.company.com\u002f And should be changed to: https:\u002f\u002fservername.company.com\u002f Currently we can't even figure out how to get a match in a search/replace expression on these UNICODE sequence string literals. It seems that no matter how we slice it, the Tcl interpreter is interpreting the "\u002f" string into the "/" translation before it does anything else. We've tried various combinations of Tcl escaping methods we know about (mainly double-quotes and using an extra "\" to escape the "\" in the UNICODE string) but are looking for more methods, preferably ones that work. Does anyone have any ideas or any pointers to where we can effectively self-educate about this? Thanks very much in advance.

• How to change mod_rewrite to avoid {REQUEST_FILENAME} in order to get around 255 character URL limit?

  - by Jeremy Reimer

  According to this answer: max length of url 257 characters for mod_rewrite? there is a maximum 255 character hard limit based on the file system for using mod_rewrite. According to the accepted answer, there are two solutions: Change the URL format of your application to a max of 255 characters between each slash. Move the Rewrite rules into the apache virtual host config and remove the REQUEST_FILENAME. I cannot use the first method, so I am trying to figure out the second. I have put the Rewrite rules into the Apache virtual host config as requested. However I cannot figure out how to remove the REQUEST_FILENAME and still have my web application framework (Dragonfly) still work. Here is the portion of the rewrite rules that I moved from .htaccess into the virtual host config file of Apache: RewriteCond %{REQUEST_FILENAME} !-d RewriteCond %{REQUEST_FILENAME} !-l RewriteCond %{REQUEST_FILENAME} !-f [OR] # if don't want Dragonfly to process html files comment # out the line below (you may need to remove the [OR] above too). RewriteCond %{REQUEST_FILENAME} \.(html|nl)$ # Main URL rewriting. RewriteRule (.*) index.cgi?$1 [L,QSA] I've tried removing {REQUEST_FILENAME} and it just breaks the framework in various ways. How do I rewrite this without using {REQUEST_FILENAME}?

• Another "Windows 7 entry missing from Grub2" Question

  - by 4x10

  Like many before me had the following problem that after installing Ubuntu (with windows 7 already installed), the grub boot loader wouldnt show windows 7 as a boot option, though i can boot fine if I use the "Choose Boot Device" options on the x220. The difference is that I try using UEFI only so many answers didn't really fit my problem, though i tried several stuffs: after running boot repair it destroyed the ubuntu boot loader custom entry in /etc/grub.d/40_custom for windows which doesnt show up many update-grub and reboots trying windows repair recovery thing while being there i also did bootrec.exe /FixBoot and update-grub and reboot again and finaly because it was so much fun, i installed linux all over again, while formatting and deleting everything linux related before that. Now that i think of it, Ubuntu also didn't notice Windows being there during the Setup and it still doesnt according to the Boot Info from Boot Repair.

Instead and whats not shown in the log for some reason: There is additional microsoft bootfiles on sda1 under /efi/microsoft/ [much stuff] I remember also doing some kind of hack to make a UEFI windows 7 usb stick. http://jake.io/b/2011/installing-windows-7-with-uefi-boot-on-an-x220-from-usb/ In short: creating and placing bootx64.efi on the stick so it can be booted in UEFI mode. boot order i decide that in my BIOS. i read somwhere that the thinkpad x220 (essential part of the serial number: 4921 http://www.lenovo.com/shop/americas/content/user_guides/x220_x220i_x220tablet_x220itablet_ug_en.pdf) doesnt really have UEFI interface or something, still, these 2 options are listed with all the other usual devices you can give a boot priority to. Right now it looks like this: Boot Priority Order 1. ubuntu 2. Windows Boot Manager 3. USB FDD 4. USB HDD 5. ATA HDD0 HITACHI [random string]

• Why is my program printing out the null termination character?

  - by Tyler Pfaff

  When I run this, it will SOMETIMES print out a null termination character. Most of the time it will, and probably 1/5 times it will print just the characters. void cryptogram::Encrypt(){ cout<<"encrypt"<tempS){ len=tempS.length(); int a=0; for(int j=0;j if(j!=len){ //if the word still has more characters j++; a=0; }else{ //if the word is done being scanned cout<<" "; } } } } } } } So that's it and this is the corresponding EXPECTED output that is printed SOMETIMES xvk bkikhxlr wggbtfkj wiylekgbdhx wjjm hko wigbtubxt xvk iwhj uedjkm glctb gvrmdiwhj iebbdielmeggtbx ctb xvtmk gbtubxvk wjjdxdthgbtubodll khvxvk imkbfdik xt xvk bkudth whj gbtfdjk hko tgxdthm whj tggtbxehdxdkm ctb mxejkhxmibdzdhtltur whj pemxdik mxejdkm mxdh cok wbk wlmt gbkgctb cteb hko zdh cgvrmdikjeiwhj qdhkmdtlturzzkjdydtivkzdmxbrw zdh zdjjlkkjeiwhj w jtixtbdh kjeiwjzdhdmxbittgkbodxv mjme whj eimj This is what normally prints though xvkÈ bkikhxlrÈ wggbtfkjÈ wiylekgbdhxÈ wjjmÈ hkoÈ wigbtubxtÈ xvkÈ iwhjÈ uedjkmÈ glctbÈ gvrmdiwhjÈ iebbdielmeggtbxÈ ctbÈ xvtmkÈ gbtubxvkÈ wjjdxdthgbtubodllÈ khvxvkÈ imkbfdikÈ xtÈ xvkÈ bkudthÈ whjÈ gbtfdjkÈ hkoÈ tgxdthmÈ whjÈ tggtbxehdxdkmÈ ctbÈ mxejkhxmibdzdhtlturÈ whjÈ pemxdikÈ mxejdkmÈ mxdhÈ cokÈ wbkÈ wlmtÈ gbkgctbÈ ctebÈ hkoÈ zdhÈ cgvrmdikjeiwhjÈ qdhkmdtlturzzkjdydtivkzdmxbrwÈ zdhÈ zdjjlkkjeiwhjÈ wÈ jtixtbdhÈ kjeiwjzdhdmxbittgkbodxvÈ mjmeÈ whjÈ eimj or some variation of an odd character at the end of each word This is what the cryptogram array is filled with by the way wyijkcuvdpqlzhtgabmxefonrs

• Why can't I display a unicode character in the Python Interpreter on Mac OS X Terminal.app?

  - by apphacker

  If I try to paste a unicode character such as the middle dot: · in my python interpreter it does nothing. I'm using Terminal.app on Mac OS X and when I'm simply in in bash I have no trouble: :~$ · But in the interpreter: :~$ python Python 2.6.1 (r261:67515, Feb 11 2010, 00:51:29) [GCC 4.2.1 (Apple Inc. build 5646)] on darwin Type "help", "copyright", "credits" or "license" for more information. >>> ^^ I get nothing, it just ignores that I just pasted the character. If I use the escape \xNN\xNN representation of the middle dot '\xc2\xb7', and try to convert to unicode, trying to show the dot causes the interpreter to throw an error: >>> unicode('\xc2\xb7') Traceback (most recent call last): File "<stdin>", line 1, in <module> UnicodeDecodeError: 'ascii' codec can't decode byte 0xc2 in position 0: ordinal not in range(128) I have setup 'utf-8' as my default encoding in sitecustomize.py so: >>> sys.getdefaultencoding() 'utf-8' What gives? It's not the Terminal. It's not Python, what am I doing wrong?! This question is not related to this question, as that indivdiual is able to paste unicode into his Terminal.

• How to detect what allowed character in current Regular Expression by using JavaScript?

  - by Soul_Master

  In my web application, I create some framework that use to bind model data to control on page. Each model property has some rule like string length, not null and regular expression. Before submit page, framework validate any binded control with defined rules. So, I want to detect what character that is allowed in each regular expression rule like the following example. "^[0-9]$" allow only digit characters like 1, 2, 3. "^[a-zA-Z_][a-zA-Z_-0-9]+$" allow only a-z, - and _ characters However, this function should not care about grouping, positioning of allowed character. It just tells about possible characters only. By the way, complex regular expression like find two words near(\bword1\W+(?:\w+\W+){1,6}?word2\b) must be ignore to verify and it should return any characters is possible. Do you have any idea for creating this function? PS. I know it easy to create specified function like numeric only for allowing only digit characters. But I need share/reuse same piece of code both data tier(contains all model validator) and UI tier without modify anything. Thanks

• Is there a name for a testing method where you compare a set of very different designs?

  - by DVK

  "A/B testing" is defined as "a method of marketing testing by which a baseline control sample is compared to a variety of single-variable test samples in order to improve response rates". The point here, of course, is to know which small single-variable changes are more optimal, with the goal of finding the local optimum. However, one can also envision a somewhat related but different scenario for testing the response rate of major re-designs: take a baseline control design, take one or more completely different designs, and run test samples on those redesigns to compare response rates. As a practical but contrived example, imagine testing a set of designs for the same website, one being minimalist "googly" design, one being cluttered "Amazony" design, and one being an artsy "designy" design (e.g. maximum use of design elements unlike Google but minimal simultaneously presented information, like Google but unlike Amazon) Is there an official name for such testing? It's definitely not A/B testing, since the main component of it (finding local optimum by testing single-variable small changes that can be attributed to response shift) is not present. This is more about trying to compare a set of local optimums, and compare to see which one works better as a global optimum. It's not a multivriable, A/B/N or any other such testing since you don't really have specific variables that can be attributed, just different designs.

• How do I properly set up and secure a production LAMP Server?

  - by Niklas

  It's very hard to find comprehensive information on this subject. Either I found short tutorials on how you perform the installation, as simple as "apt-get install apache2", or outdated tutorials. So I was hoping I could get some professional information from my fellow members of the Ubuntu community :D I have performed a normal Ubuntu Server 11.04 with LAMP, SAMBA and SSH installed through the system installation. But I'm having some trouble setting up virtual hosts and to make the system secure enough to expose the server to the web. I've somewhat followed this tutorial this far. I have 3 sites in /etc/apache2/sites-available which all looks like this except for different site names: <VirtualHost example.com> ServerAdmin webmaster@localhost ServerAlias www.edunder.se DocumentRoot /var/www/sites/example CustomLog /var/log/apache2/www.example.com-access.log combined </VirtualHost> And I have enabled them with the command a2ensite so I have symbolic links in /etc/apache2/sites-enabled. My /etc/hosts file has these lines: 127.0.0.1 localhost 127.0.1.1 Ubuntu.lan Ubuntu 127.0.0.1 localhost.localdomain localhost example.com www.example.com 127.0.0.1 localhost.localdomain localhost example2.com www.example2.com 127.0.0.1 localhost.localdomain localhost example3.com www.example3.com And I can only access one of them from the browser (I have lynx installed on the server for testing purposes) so I guess I haven't set them up properly :) How should I proceed to get a secure and proper setup? I also use MySQL and I think that this tutorial will be enough to set up SSH securely. Please help me understanding Apache configuration better since I'm new to setting up my own server (I've only run XAMPP earlier) and please advise regarding how I should setup a firewall as well :D

• How to Set Ubuntu 12.04 to it's factory settings like when u first installed it?

  - by Cameron

  Well, this is a simple answered question, from the title, but my real problem is hard af. I have set ubuntu to use root, then it wouldn't let me log into the admin account only root and guest I deleted the admin account, remade another, then attempted to disable root account. This failed - I messed up the password, the original password was "root" I also didn't set a password for my new admin account, so It says it has one, whats the default password for it? I can't moderate my ubuntu system at all now. I have tried to drop to cmd shell thing, it asks for the root password, i type 'root' and any other possible passwords, it doesn't work. To reset ubuntu to factory settings i have found that i could enter the following code: sudo dpkg-reconfigure -phigh -a sudo Requires admin password, that I cant find out without root password and I don;t know. My goal is to try to fix this without remaking a bootable usb for ubuntu, because I lost the one i made for this. so If i can't, please say so. If you can help thanks!

• How to build Gantt chart from a set of Redmine tickets without filling dates in all of them?

  - by Alexander Gladysh

  Redmine 1.1.1 I've created a set of tickets for a new project. In each issue I filled Subject, Description and Estimated time fields. I also filled blocks/blocked by dependencies in Related issues. But the Gantt chart for this project is empty (that is, it contains all the tasks, but does not contain any "bars" for them). I need to get a Gantt chart (or any other visual representation) to show to other project members. I'd hate to type all that information again into OpenProj. Is there a way to get a serviceable Gantt chart from the Redmine? Update: In the answers below I read that to get working Gantt chart I have to input start date and due date manually for each issue. I believe that this information should be inferred automatically from start date of first ticket (first — depenency-wise), estimated time of each ticket, dependency graph, resource assignment and working hours calendar. Just as it happens in any minimally sane Gantt chart project management tool. To enter this information by hand and to keep it up-to-date manually as the project evolves is insane waste of time. Is there a way to generate Gantt chart from the set of Redmine tickets without filling in all this information manually? (Solutions involving data export + import in sane tool or involving existing plugins are perfectly acceptable.)

• How do I set up a proxy server in Xubuntu?

  - by Dolphin

  NOTICE: I am completely allowed to do this. This is not meant for accessing sites I am not supposed to go on I know that most threads with "Proxy" in the title have to do with getting to sites they're not supposed to go on. I hope that I can get this to be as easy as possible. I hope it can be as easy as setting up an OpenSSH server. What happened My dad has just screwed something up in our router settings, and I can't access Google anymore because if it. I need to be able to access Google. He doesn't like me in the router because he thinks I will make it worse. (I am sick of Bing and Yahoo) So I want to set up a proxy server that will allow me to work around what he screwed up. What I want to do I want to host it on a computer in my grandpa's house, and access it with my computer at my dad's house. It's running Xubuntu. I want it to work with the Mozilla Firefox on my computer at my dad's house running Ubuntu 11.10. How can I set this up? This is only temporary until he fixes whatever he did.

• How to optimize calls to multiple APIs at once and return as one set?

  - by Martin

  I have a web app that searches across 2 APIs right now. I have my own Restful web service that I call, and it does all the work on the backend to asynchronously call the 2 APIs and concatenate them into one result set for my web app to use. I want to scale this out and add as many other APIs as I can (currently looking at about 10 more). But as I add APIs, the call to my service gets (potentially) slower and more complex. How do I handle one API not responding ... and other issues that arise? What would be the best way to approach this? Should I create a service call for each API, that way each one is independent and not coupled to all the other calls? Is there a way on the backend to handle the multiple API calls without all the extra complexity it adds? If I go the route of a service call per API, now my client code gets more complex (and I have a lot of clients)? And it's more work for the client, and since I have mobile apps, it will cost the client more data usage. If I go one service call, is there a way to set up some sort of connection so I can return data as I get it, in case one service call hangs?

• How to set individual NTFS partitions permissions behaviour for each user account?

  - by ryniek

  I have two NTFS partitions (DOWNLOADS for downloaded files and VM for my VirtualBox .vdi file) for which i must have full permissions for my allday use account. They should be also automounting when i login to this account. But i've also set Guest account for guests. For Guest account, i want make VM partition fully disabled and invisible (and thus it mustn't automount) but DOWNLOADS partition should be shared with limited privileges with Guest account. Editing fstab i'm able to share DOWNLOADS partition with Guest on limited privileges but VM can be only set to limited and have disabled automounting - so guest can't mount it but it still can be seen in Nautilus, plus I must always mount it manually when i login to allday account. Is there some trick to make what i want? Here's my fstab config: # /etc/fstab: static file system information. # # <file system> <mount point> <type> <options> <dump> <pass> proc /proc proc nodev,noexec,nosuid 0 0 #Entry for /dev/sda1 : UUID=35e66658-5ee9-40cf-bf56-8204959e3df0 / xfs defaults 01 #Entry for /dev/sda2 : UUID=26c714cf-4236-45e7-9c46-cfcf91a215ae /home xfs defaults 02 #Entry for /dev/sda5 : UUID=1315BCB027C44639 /media/DOWNLOADS ntfs-3g auto,uid=1000,gid=1000,umask=0022,nodev,locale=pl_PL.utf8 0 0 #Entry for /dev/sda6 : UUID=60FF39EB72B72264 /media/VM ntfs noauto,uid=1000,gid=1000,umask=0077,nodev,locale=pl_PL.utf8 0 0 #Entry for /dev/sda7 : UUID=c52411f5-105c-45d1-971f-412f962c350e none swap sw 0 0 /dev/fd0 /media/floppy0 auto rw,user,noauto,exec,utf8 0 0 Thanks

• Why won't Webmaster Tools let me set a preferred domain? (says to verify, but it should already be)

  - by Su'

  I've got a domain that I apparently forgot to set a preferred domain for, so I just tried to do it. Webmaster Tools instead popped up a little box: Part of the process of setting a preferred domain is to verify that you own http://www.example.com/. Please verify http://www.example.com/. I'm running into some problems following these instructions: As far as I can tell I already did verify sometime in the past. There's a TXT DNS record with the gibberish Google tells you to set for it that I couldn't have come up with myself. …and nothing is telling me this information is bad. So let's assume the site is somehow not actually verified. All the various methods' instructions start with "click the Manage Site button next to the site you want, and then click Verify this site." That button doesn't even exist on my screens. (It presumably goes away when you successfully verify?) Those instructions were all updated pretty recently, and the DNS one in particular just a couple weeks ago so it seems a bit unlikely they're inaccurate. I am not using Apps, and won't be, so can't try out the verification through there. Note that I also have another domain that I have not done any verification for which is showing the same behavior(no such button, being told to verify when it seems impossible etc.) so something appears to just be broken. I already have a no-www process in place server-side, so we can skip that. I'm just trying to get the box checked off in GWT. If I don't get any resolution, I'll eventually scrap the TXT record and see if the site gets un-verified(or whatever since it thinks it isn't), and see if I can just restart the process. It's not urgent so I'm just trying to figure out if I've gone blind to something or what. Did the button move?

• Objective-C Basic class related question, retaining the value of a specific object using a class fil

  - by von steiner

  Members, scholars, code gurus. My background is far from any computer programming thus my question may seems basic and somewhat trivial to you. Nevertheless it seems that I can't put my head around it. I have googled and searched for the answer, just to get myself confused even more. With that, I would kindly ask for a simple explanation suitable for a non technical person such as myself and for other alike arriving to this thread. I have left a comment with the text "Here is the issue" below, referring to my question. // character.h #import <Foundation/Foundation.h> @interface character : NSObject { NSString *name; int hitPoints; int armorClass; } @property (nonatomic,retain) NSString *name; @property int hitPoints,armorClass; -(void)giveCharacterInfo; @end // character.m #import "character.h" @implementation character @synthesize name,hitPoints,armorClass; -(void)giveCharacterInfo{ NSLog(@"name:%@ HP:%i AC:%i",name,hitPoints,armorClass); } @end // ClassAtLastViewController.h #import <UIKit/UIKit.h> @interface ClassAtLastViewController : UIViewController { } -(void)callAgain; @end // ClassAtLastViewController.m #import "ClassAtLastViewController.h" #import "character.h" @implementation ClassAtLastViewController - (void)viewDidLoad { //[super viewDidLoad]; character *player = [[character alloc]init]; player.name = @"Minsc"; player.hitPoints = 140; player.armorClass = 10; [player giveCharacterInfo]; [player release]; // Up until here, All peachy! [self performSelector:@selector(callAgain) withObject:nil afterDelay:2.0]; } -(void)callAgain{ // Here is the issue, I assume that since I init the player again I loss everything // Q1. I loss all the data I set above, where is it than? // Q2. What is the proper way to implement this character *player = [[character alloc]init]; [player giveCharacterInfo]; } Many thanks in advance, Kindly remember that my background is more related to Salmons breeding than to computer code, try and lower your answer to my level if it's all the same to you.

• How can I Include Multiples Tables in my linq to entities eager loading using mvc4 C#

  - by EBENEZER CURVELLO

  I have 6 classes and I try to use linq to Entities to get the SiglaUF information of the last deeper table (in the view - MVC). The problem is I receive the following error: "The ObjectContext instance has been disposed and can no longer be used for operations that require a connection." The view is like that: > @model IEnumerable<DiskPizzaDelivery.Models.EnderecoCliente> > @foreach (var item in Model) { > @Html.DisplayFor(modelItem => item.CEP.Cidade.UF.SiglaUF) > } The query that i use: var cliente = context.Clientes .Include(e => e.Enderecos) .Include(e1 => e1.Enderecos.Select(cep => cep.CEP)) .SingleOrDefault(); The question is: How Can I improve this query to pre loading (eager loading) "Cidade" and "UF"? See below the classes: public partial class Cliente { [Key] [DatabaseGeneratedAttribute(DatabaseGeneratedOption.Identity)] public int IdCliente { get; set; } public string Email { get; set; } public string Senha { get; set; } public virtual ICollection<EnderecoCliente> Enderecos { get; set; } } public partial class EnderecoCliente { public int IdEndereco { get; set; } public int IdCliente { get; set; } public string CEPEndereco { get; set; } public string Numero { get; set; } public string Complemento { get; set; } public string PontoReferencia { get; set; } public virtual Cliente Cliente { get; set; } public virtual CEP CEP { get; set; } } public partial class CEP { public string CodCep { get; set; } public string Tipo_Logradouro { get; set; } public string Logradouro { get; set; } public string Bairro { get; set; } public int CodigoUF { get; set; } public int CodigoCidade { get; set; } public virtual Cidade Cidade { get; set; } } public partial class Cidade { public int CodigoCidade { get; set; } public string NomeCidade { get; set; } public int CodigoUF { get; set; } public virtual ICollection<CEP> CEPs { get; set; } public virtual UF UF { get; set; } public virtual ICollection<UF> UFs { get; set; } } public partial class UF { public int CodigoUF { get; set; } public string SiglaUF { get; set; } public string NomeUF { get; set; } public int CodigoCidadeCapital { get; set; } public virtual ICollection<Cidade> Cidades { get; set; } public virtual Cidade Cidade { get; set; } } var cliente = context.Clientes .Where(c => c.Email == email) .Where(c => c.Senha == senha) .Include(e => e.Enderecos) .Include(e1 => e1.Enderecos.Select(cep => cep.CEP)) .SingleOrDefault(); Thanks!

• How can I set my screen resolution to match my TV?

  - by Scott Severance

  I have a computer in my classroom that's connected to an LG smart TV (that's actually not so smart. I wouldn't recommend buying one.). For the touch interface, the TV wants a resolution of 1920x1080 at 60Hz. However, I can't seem to set the computer to that resolution. The display settings only offer 1024x768 and 640x480. The computer dual boots with Windows XP, where widescreen options are available in approximately the required size, but the exact resolution -- or even aspect ratio-- isn't available in XP either. I tried the following command: xrandr -s 1920x1080 -r 60 The response was: Size 1920x1080 not found in available modes Back in the old days, the solution would be to edit xorg.conf. However, since that file no longer exists, and I haven't found up-to-date info, I don't know what else to do. If it helps, this machine will never be connected to a different display, so resolution flexibility isn't important. Here's the output of lshw: *-display:0 description: VGA compatible controller product: 4 Series Chipset Integrated Graphics Controller vendor: Intel Corporation physical id: 2 bus info: pci@0000:00:02.0 version: 03 width: 64 bits clock: 33MHz capabilities: vga_controller bus_master cap_list rom configuration: driver=i915 latency=0 resources: irq:42 memory:fe800000-febfffff memory:d0000000-dfffffff ioport:ecd8(size=8) *-display:1 UNCLAIMED description: Display controller product: 4 Series Chipset Integrated Graphics Controller vendor: Intel Corporation physical id: 2.1 bus info: pci@0000:00:02.1 version: 03 width: 64 bits clock: 33MHz According to the system settings, my graphics driver is unknown and my "experience" is standard.

• Bypass cache for mobile user agents, VARNISH+NGINX+W3CACHE

  Right now I'm running Wordpress w/ W3 Cache on nginx with varnish front end. I'm trying to use the WP Touch Pro plugin for wordpress to display mobile sites, but it is not working. Shows the desktop theme still. I've put the mobile user agents in the rejected user agents box in w3 cache. Here is the nginx config w3 cache spit out: BEGIN W3TC Page Cache cache location ~ /wp-content/w3tc/pgcache.*html$ { expires modified 3600s; add_header X-Powered-By "W3 Total Cache/0.9.2.4"; add_header Vary "Accept-Encoding, Cookie"; } location ~ /wp-content/w3tc/pgcache.*gzip$ { gzip off; types {} default_type text/html; expires modified 3600s; add_header X-Powered-By "W3 Total Cache/0.9.2.4"; add_header Vary "Accept-Encoding, Cookie"; add_header Content-Encoding gzip; } # END W3TC Page Cache cache # BEGIN W3TC Browser Cache gzip on; gzip_types text/css application/x-javascript text/x-component text/richtext image/svg+xml text/plain text/xsd text/xsl text/xml image/x-icon; location ~ \.(css|js|htc)$ { expires 31536000s; add_header X-Powered-By "W3 Total Cache/0.9.2.4"; } location ~ \.(html|htm|rtf|rtx|svg|svgz|txt|xsd|xsl|xml)$ { expires 3600s; add_header X-Powered-By "W3 Total Cache/0.9.2.4"; } location ~ \.(asf|asx|wax|wmv|wmx|avi|bmp|class|divx|doc|docx|eot|exe|gif|gz|gzip|ico|jpg|jpeg|jpe|mdb|mid|midi|mov|qt|mp3|m4a|mp4|m4v|mpeg|mpg|mpe|mpp|otf|odb|odc|odf|odg|odp|ods|odt|ogg|pdf|png|pot|pps|ppt|pptx|ra|ram|svg|svgz|swf|tar|tif|tiff|ttf|ttc|wav|wma|wri|xla|xls|xlsx|xlt|xlw|zip)$ { expires 31536000s; add_header X-Powered-By "W3 Total Cache/0.9.2.4"; } # END W3TC Browser Cache # BEGIN W3TC Minify core rewrite ^/wp-content/w3tc/min/w3tc_rewrite_test$ /wp-content/w3tc/min/index.php?w3tc_rewrite_test=1 last; rewrite ^/wp-content/w3tc/min/(.+\.(css|js))$ /wp-content/w3tc/min/index.php?file=$1 last; # END W3TC Minify core # BEGIN W3TC Page Cache core rewrite ^(.*\/)?w3tc_rewrite_test$ $1?w3tc_rewrite_test=1 last; set $w3tc_rewrite 1; if ($request_method = POST) { set $w3tc_rewrite 0; } if ($query_string != "") { set $w3tc_rewrite 0; } if ($http_host != "mysite.com") { set $w3tc_rewrite 0; } set $w3tc_rewrite2 1; if ($request_uri !~ \/$) { set $w3tc_rewrite2 0; } if ($request_uri ~* "(sitemap(_index)?\.xml(\.gz)?|[a-z0-9_\-]+-sitemap([0-9]+)?\.xml(\.gz)?)") { set $w3tc_rewrite2 1; } if ($w3tc_rewrite2 != 1) { set $w3tc_rewrite 0; } set $w3tc_rewrite3 1; if ($request_uri ~* "(\/wp-admin\/|\/xmlrpc.php|\/wp-(app|cron|login|register|mail)\.php|\/feed\/|wp-.*\.php|index\.php)") { set $w3tc_rewrite3 0; } if ($request_uri ~* "(wp\-comments\-popup\.php|wp\-links\-opml\.php|wp\-locations\.php)") { set $w3tc_rewrite3 1; } if ($w3tc_rewrite3 != 1) { set $w3tc_rewrite 0; } if ($http_cookie ~* "(comment_author|wp\-postpass|wordpress_\[a\-f0\-9\]\+|wordpress_logged_in)") { set $w3tc_rewrite 0; } if ($http_user_agent ~* "(W3\ Total\ Cache/0\.9\.2\.4|iphone|ipod|ipad|aspen|incognito|webmate|android|dream|cupcake|froyo|blackberry9500|blackberry9520|blackberry9530|blackberry9550|blackberry\ 9800|blackberry\ 9780|webos|s8000|bada)") { set $w3tc_rewrite 0; } set $w3tc_ua ""; if ($http_user_agent ~* "(acer\ s100|android|archos5|blackberry9500|blackberry9530|blackberry9550|blackberry\ 9800|cupcake|docomo\ ht\-03a|dream|htc\ hero|htc\ magic|htc_dream|htc_magic|incognito|ipad|iphone|ipod|kindle|lg\-gw620|liquid\ build|maemo|mot\-mb200|mot\-mb300|nexus\ one|opera\ mini|samsung\-s8000|series60.*webkit|series60/5\.0|sonyericssone10|sonyericssonu20|sonyericssonx10|t\-mobile\ mytouch\ 3g|t\-mobile\ opal|tattoo|webmate|webos)") { set $w3tc_ua _high; } set $w3tc_ref ""; set $w3tc_ssl ""; set $w3tc_enc ""; if ($http_accept_encoding ~ gzip) { set $w3tc_enc _gzip; } set $w3tc_ext ""; if (-f "$document_root/wp-content/w3tc/pgcache/$request_uri/_index$w3tc_ua$w3tc_ref$w3tc_ssl.html$w3tc_enc") { set $w3tc_ext .html; } if ($w3tc_ext = "") { set $w3tc_rewrite 0; } if ($w3tc_rewrite = 1) { rewrite .* "/wp- content/w3tc/pgcache/$request_uri/_index$w3tc_ua$w3tc_ref$w3tc_ssl$w3tc_ext$w3tc_enc" last; } # END W3TC Page Cache core And here is what I have in my varnish vcl.. sub vcl_recv { # Add a unique header containing the client address remove req.http.X-Forwarded-For; set req.http.X-Forwarded-For = client.ip; # Device detection set req.http.X-Device = "desktop"; if ( req.http.User-Agent ~ "iP(hone|od|ad)" || req.http.User-Agent ~ "Android" ) { set req.http.X-Device = "smart"; } elseif ( req.http.User-Agent ~ "(SymbianOS|BlackBerry|SonyEricsson|Nokia|SAMSUNG|^LG)" ) { set req.http.X-Device = "cell"; } Any help is greatly appreciated, I've been banging my head against this for 2 days..
