• Keyring no longer prompts for password when SSH-ing

  - by Lie Ryan

  I remember that I used to be able to do ssh [email protected] and have a prompt asks me for a password to unlock the keyring for the whole GNOME session so subsequent ssh wouldn't need to enter the keyring password any longer (not quite sure if this is in Ubuntu or other distro). But nowadays doing ssh [email protected] would ask me, in the terminal, my keyring password every single time; which defeats the purpose of using SSH keys. I checked $ cat /etc/pam.d/lightdm | grep keyring auth optional pam_gnome_keyring.so session optional pam_gnome_keyring.so auto_start which looks fine, and $ pgrep keyring 1784 gnome-keyring-d so the keyring daemon is alive. I finally found that SSH_AUTH_SOCK variable (and GNOME_KEYRING_CONTROL and GPG_AGENT_INFO and GNOME_KEYRING_PID) are not being set properly. What is the proper way to set this variable and why aren't they being set in my environment (i.e. shouldn't they be set in default install)? I guess I can set it in .bashrc, but then the variables would only be defined in bash session, while that is fine for ssh, I believe the other environment variables are necessary for GUI apps to use keyring.

• Ubuntu 12.10 with kernel 3.5.0-18

  - by Chaitanya

  I had ubuntu 12.04 with kernel 3.0.2. Today I have updated my system and got 12.10 with kernel 3.5.0-18. Now when I boot my machine with 3.5 kernel, it starts until the page where I enter my password. Within seconds, I get a page with looooong list of some commands or list. I cant take screenshot of that. It looks something like, [1.2234978942837]kjsahfa;lsfksld;fkjsf;owieurwirejw/rnw;erkjwelrjw2309480432 [1.3294823498230948]as;lfjsf;iuwrijrwjlkerjw;rekwer;lkwjre;lkjRIJWEORIWE'JJA; something like this. Luckily, in my boot page, I have 3.0.2 kernel also. When I boot with 3.0.2 kernel there is no problem. But when I boot with 3.5.0, it throws that wierd error. I wont be able to do anything at that time. None of the keys work. I have to forcibly shutdown the machine and restart with 3.0.2 kernel. Please help..... Thanks, Chaitanya.

• running adb via wifi on ubuntu 13.04

  - by Blaze Tama

  First, im new on linux so please bear with me. I have a rooted android phone and i was able to run the adb via wifi network on windows, where i just need to go to the adb's directory and type adb connect. However, i can't just do that in my ubuntu. Everytime i enter adb connect, the terminal always said that i dont have the adb and i must install it. When i check the ADT Bundle (I downloaded the bundled one from here), i can see the adb is there inside the platform-tools folder. I already tried to change the directory to the platform-tools and run the adb connect from there, but its still not working. Do i need to install the adb again via terminal? Or did i miss something? You may be wondering why dont i just download the adb (again) via terminal and do trial and error? The answer is because i dont have a good internet connection, so i want to avoid unnecessary downloads. Thanks for your time :D

• Setting up Clojure Project And Sub Projects

  - by octopusgrabbus

  This is primarily a lein question about setting up a major project and its sub-projects, and is not intended to be a discussion question. Instead, I am interested in either a pointer to documentation or to a Clojure/lein best practices link. I have a municipal property assessments application that splits two master flies into different subset files, depending on whether a billing transfer is taking place or we want to batch update new accounts, rather than making our assessment department enter new accounts once in their system and then again in the tax collection system. My application is going to be large enough, that I can see a common library lein project with support functions, like splitting apart the files, and then individual lein projects that use the common library. Should the lein projects be set up at the same level and support included through the project.clj/core.clj files? Is there an advantage to creating lein new projects underneath a major project? Is there a problem with combing all functions in one project? I can probably make my one core.clj contain all flavors of the program, but coming from a C/C++ and Python background, I would prefer to have a lot of little projects.

• Colored Vertical Lines upon boot and nomodeset DOES NOT fix it

  - by user2851032

  I have installed Lubuntu 13.04 on a Dell Inspiron 1501 laptop, rebooted the machine and encountered this problem. I edited the GRUB configuration to remove "quite splash" and enter "nomodeset", updated grub, and everything was fine. I could reboot the machine without any trouble. However, if I unplug the machine, wait a few seconds, and plug it back in, the problem with the colored lines comes back and nomodeset no longer helps to solve the problem. I tried using radeon.modeset=0 instead of nomodeset and that also works on multiple reboots until I unplug the machine and plug it back in. I was finally able to get around the problem by entering "radeon.exapixmaps=0" instead of radeon.modeset=0. I suppose I kind of made up that boot option using some information from an Arch Wiki page. This would work throughout reboots and even if I unplugged the laptop. It was working fine for quite a while. A few weeks later, I had some unrelated issues with the Java iced-tea plugin, and since 13.10 had just come out, I thought I would try upgrading. So upgrading didn't fix the problem with Java, and after unplugging the machine and trying to use it later, I was back to this problem with the black screen and colored vertical lines. I am completely out of ideas on what to try. It took me a week to figure out how to get it working the first time, but the solution I had isn't working anymore.

• https:// search results appearing on Google for purely http:// site

  - by hydrurga

  I started weeding through my site's search results from Google today, using a site: search, to determine if there are any links that cause 404s and thus need redirecting. To my amazement I noticed numerous https:// results relating to various pages. My site doesn't have a SSL certificate, doesn't serve such pages, doesn't internally link to https:// pages, doesn't include any such files in its sitemap.xml and, for all of these, never has. I decided to do a Google search for https://<my site> and found one site that incorrectly refers to the root of my site with a https:// prefix - I will try to contact them to get them to correct this. I'm not sure however how Googlebot managed to index the non-root files as https://. I can't find any external links to them and surely, without certification, Googlebot should have stalled at the first request? I've just added the following lines to the site's .htaccess (although the surfer still has to navigate through the browser's "This site is a security risk. Abandon hope all ye who enter here!" message(s) first to get there): RewriteEngine On RewriteCond %{HTTPS} on RewriteRule ^(.*)$ http://www.<my site>.org/$1 [R=301,L] replacing <my site> with my domain name. My big question is this though - I would like to use the Google Webmaster Tools Remove URLs feature to remove the https:// pages from the index. Can I be guaranteed that this will only remove the https:// versions of each relevant page and not the valid http:// versions? My thanks to anyone who can help me out with this particular question and the issue in general.

• Is this a ridiculous way to structure a DB schema, or am I completely missing something?

  - by Jim

  I have done a fair bit of work with relational databases, and think I understand the basic concepts of good schema design pretty well. I recently was tasked with taking over a project where the DB was designed by a highly-paid consultant. Please let me know if my gut intinct - "WTF??!?" - is warranted, or is this guy such a genius that he's operating out of my realm? DB in question is an in-house app used to enter requests from employees. Just looking at a small section of it, you have information on the users, and information on the request being made. I would design this like so: User table: UserID (primary Key, indexed, no dupes) FirstName LastName Department Request table RequestID (primary Key, indexed, no dupes) <...> various data fields containing request details UserID -- foreign key associated with User table Simple, right? Consultant designed it like this (with sample data): UsersTable UserID FirstName LastName 234 John Doe 516 Jane Doe 123 Foo Bar DepartmentsTable DepartmentID Name 1 Sales 2 HR 3 IT UserDepartmentTable UserDepartmentID UserID Department 1 234 2 2 516 2 3 123 1 RequestTable RequestID UserID <...> 1 516 blah 2 516 blah 3 234 blah The entire database is constructed like this, with every piece of data encapsulated in its own table, with numeric IDs linking everything together. Apparently the consultant had read about OLAP and wanted the 'speed of integer lookups' He also has a large number of stored procedures to cross reference all of these tables. Is this valid design for a small to mid-sized SQL DB? Thanks for comments/answers...

• A project idea I've got...

  - by Mr Teeth

  Hi, Next year I will be doing a final year project at Uni. I've already thought of one and was wondering what you guys think of it. I want to create a University Information Search for prospective students who are trying to look for an affordable University to attend. It will depend on the student's family income and the grades they get. They enter in those two parameters (and some more) and it comes up with a list of suitable Unis based on their criteria. This is not about the price of tution fee. It's mostly to do with the cost of living. Stuff like: Rent (if living in a private flat). Student Accomadation. Cost of traveling to your home and back (for holidays). ...and some other stuff stuff I haven't thought about yet. It'll mostly be GUI driven with some textual information. I'm also thinking of using it as a website interface. What do you guys think? Can I program something like this Java? If there's any holes you see in my idea please tell me.

• What is an effective way to convert a shared memory-mapped system to another data access model?

  - by Rob Jones

  I have a code base that is designed around shared memory. Each process that needs to access the memory maps it into its own address space. The data structures in the shared memory are directly accessed, that is, there is no API. For example: Assume the following: typedef struct { int x; int y; struct { int a; int b; } z; } myStruct; myStruct s; Then a process might access this structure as: myStruct *s = mapGlobalMem(); And use it as: int tmpX = s->x; The majority of the information in the global structure is configuration information that is set once and read many times. I would like to store this information in a database and develop an API to access the database. The problem is, these references are sprinkled throughout the code. I need a way to parse the code and identify global structure references that will need to be refactored. I've looked into using ANTLR to create a parser that will identify references to a small set of structures and enter them into a custom symbol table. I could then use this symbol table to identify which source files need to be refactored. It looks like a promising approach. What other approaches are there? Of course, I'm looking for a programmatic approach. There are far too many source files to examine each one visually. This is all ordinary ANSI C. Nothing else.

• One Step-Ahead A-Star

  - by Jonathan Dickinson

  I am attempting to create a server-centric RTS (as opposed to usual parallel synchronised simulation route of most RTS games today) - however I am still leveraging the discreet N-turns-ahead paradigm discussed by one of the AOE developers on Gamasutra. I have [possibly questionably?] decided that the path finding should only ever find the next cell the entity needs to move to, and was wondering if anyone has any clever ideas on how to optimize the algorithm for this specific scenario - or any other ideas on how to keep the pathfinding as lean as possible on the server. I have investigated a few possible algorithms but could only come up with one appropriation: Tiered A-Star - Relatively large T1 tiles, work out (and cache) each cell as you enter it. Other than that: doing the full A-Star pass and caching the entire path, which might use too much memory if a large amount of units are present. I know about the existence of naive progressive pathfinding algorithms (if you hit a block, turn in the direction closer to your target etc.) but they suffer from infinite feedback loops - and very poor pathing even if visited blocks are memorised. Not an option. Many thanks.

• Am I missing something about these considerations about Leaderboard's database's schema?

  - by misiMe

  I just finished to develop a mobile game, now I want to implement an online leaerboard using mysql. I'm wondering about the database's schema, I thought about some possibilities: (I didn't got in detail with syntax because my question is just about the logic of it) Name: string; Score: integer I thought to ask the name just the first time. If, in the future, you will modify that, it will call just an update to the name associated with your id. Leaderboard(ID, Name, Score) ID: integer autoincrement, PrimaryKey With this kind of idea maybe the db will grow fast because if you choose everytime a different name for the score, it will add a new entry. Leaderboard(PhoneId, Name, Score) Here PhoneId will be the unique identifier of the phone, PrimaryKey. A con of this choice is that if you want to play with your friends' phone, you can't put a different name for the score. Leaderboard(Name, Score) Here Name is PrimaryKey. With that, if you enter a name that already exists, you will be prompted to choose another one. Do you agree with this considerations? What will you do? Am I missing something?

• Authenticate native mobile app using a REST API

  - by Supercell

  I'm starting a new project soon, which is targeting mobile application for all major mobile platforms (iOS, Android, Windows). It will be a client-server architecture. The app is both informational and transactional. For the transactional part, they're required to have an account and log in before a transaction can be made. I'm new to mobile development, so I don't know how the authentication part is done on these platforms. The clients will communicate with the server through a REST API. Will be using HTTPS ofcourse. I haven't yet decided if I want the user to log in when they open the app, or only when they perform a transaction. I got the following questions: 1) Like the Facebook application, you only enter your credentials when you open the application for the first time. After that, you're automatically signed in every time you open the app. How does one accomplish this? Just simply by encrypting and storing the credentials on the device and sending them every time the app starts? 2) Do I need to authenticate the user for each (transactional) request made to the REST API or use a token based approach? Please feel free to suggest other ways for authentication. Thanks!

• Session Tracking - Advantages and Disadvantages

  I use to work for a major internet company that sold Dental Plans to customers through their large customer-driven websiteto consumers. They start tracking their users as soon as they hit their web servers, and then they log everything they can about the user. There are a lot of benefits for using session tracking for both the user and the website. Users can benefit from session tracking due to the fact that a website can retain pertaining information for the user so that they do not have to re-enter the same information repeatedly. In addition, websites can hold specific items in a cart for each user so that they can pay for all of their  items at once when they are ready to complete their purchases. Websites can also benefit from session tracking because they can determine where a specific user came from and which advertising partner gave them a sale. This information is very useful when deciding on where to spend an advertising budget. There is only one real disadvantage when it comes to session tracking, Users can not really control what is actually tracked by a website. Yes, they can disable cookies and this will help, but that means that no tracking can be done at all. Most sites require users to have cookies enabled in order for users to make purchases or login to their accounts.

• Advice on software infrastructure for a FLOSS bounty site

  - by michaeljt

  I am planning to set up a simple web site where people can offer bounties for work on FLOSS projects. Unfortunately I have no experience at web development (I am a C/C++ developer), so I was hoping someone might be able to suggest out-of-the-box packages (preferably Debian ones) I could use to build the site from. My idea of how the site would work is to keep things as simple as possible. The person proposing a bounty would enter a description with relevant links (particularly to a bugtracker entry with the project the work is to be done on, where the real discussion and work would take place) and information and place an initial contribution. Other people would be able to add (donate, not pledge) contributions, but any discussion would take place on the project's bugtracker. I am also planning to run a mailing list rather than a forum (at least initially), so that is not a requirement. Paypal seems to me to be the handiest payment mechanism. So overall what I need is probably a simple interface with Paypal integration and a simple database backend. I hope this is the right place for my question, if not I would be grateful for pointers to somewhere better. And of course, this is purely about the technical side, though I am more than happy to discuss other aspects of the project elsewhere.

• Two graphical entities, smooth blending between them (e.g. asphalt and grass)

  - by Gabriel Conrad

  Supposedly in a scenario there are, among other things, a tarmac strip and a meadow. The tarmac has an asphalt texture and its model is a triangle strip long that might bifurcate at some point into other tinier strips, and suppose that the meadow is covered with grass. What can be done to make the two graphical entities seem less cut out from a photo and just pasted one on top of the other at the edges? To better understand the problem, picture a strip of asphalt and a plane covered with grass. The grass texture should also "enter" the tarmac strip a little bit at the edges (i.e. feathering effect). My ideas involve two approaches: put two textures on the tarmac entity, but that involves a serious restriction in how the strip is modeled and its texture coordinates are mapped or try and apply a post-processing filter that mimics a bloom effect where "grass" is used instead of light. This could be a terrible failure to achieve correct results. So, is there a better or at least a more obvious way that's widely used in the game dev industry?

• 15 Puzzle Shuffle Method Issues

  - by Codemiester

  I am making a 15 puzzle game in C# that allows the user to enter a custom row and column value up to a maximum of a 10 x 10 puzzle. Because of this I am having problems with the shuffle method. I want to make it so the puzzle is always solvable. By first creating a winning puzzle then shuffling the empty space. The problem is it is too inefficient to call every click event each time. I need a way to invoke the click event of a button adjacent to the empty space but not diagonal. I also use an invisible static button for the empty spot. The PuzzlePiece class inherits from Button. I am not too sure how to do this. I would appreciate any help. Thanks here is what I have: private void shuffleBoard() { //5 is just for test purposes for (int i = 0; i < 5; i++) { foreach (Control item in this.Controls) { if (item is PuzzlePiece) { ((PuzzlePiece)item).PerformClick(); } } } } void PuzzlePiece_Click(object sender, EventArgs e) { PuzzlePiece piece = (PuzzlePiece)sender; if (piece.Right == puzzleForm.emptyPiece.Left && piece.Top == puzzleForm.emptyPiece.Top) { movePiece(piece); } else if (piece.Left == puzzleForm.emptyPiece.Right && piece.Top == puzzleForm.emptyPiece.Top) { movePiece(piece); } else if (piece.Top == puzzleForm.emptyPiece.Bottom && piece.Left == puzzleForm.emptyPiece.Left) { movePiece(piece); } else if (piece.Bottom == puzzleForm.emptyPiece.Top && piece.Left == puzzleForm.emptyPiece.Left) { movePiece(piece); } }

• Microsoft Tag Tagged Me

  - by Brian Schroer

  I got EXTREMELY lucky last week and won an HP Mini 311 notebook from a Microsoft Tag Twitter contest. I did my required tweet to enter last Tuesday, and one hour later received notification that I had won the weekly drawing. Apparently you can tweet up to 500 times (I pity the followers of those who do that), so it was really lucky that I won, and I sympathize with those who had been really trying. If you would like to try your luck, there are seven weekly prizes left, and you can find out about the contest here: http://tag.microsoft.com/ttcontest.aspx For a free PC, I thought it was the least I could do to find out what Microsoft Tag is. I was vaguely aware of those pastel-y triangle-y square things that look like someone put one of Don Johnson’s Miami Vice outfits through a shredder, and knew that the company I work for (one of the world’s largest consumer products companies) was looking into putting them on our products, packaging and advertising, but didn’t know much more about the technology. I thought they were just an improvement over bar codes, and would be used in retail store scanners, but I was mistaken. These tags are meant to be scanned by consumers using their mobile phones, to get instant access to information, websites, reviews, etc. Scanning a tag can open a web page, import a contact card, or dial a phone number, play a video… Tag reader software can be installed on Windows Mobile, iPhone, Symbian, Blackberry, Android, J2ME, and other phones (and I suspect that it will be available for Windows Phone 7 also :). There are built-in tracking, metrics and analysis tools, to help companies using Tag make decisions about their marketing expenditures. (And they don’t have to look Miami Vice-y – They can be customized to reflect the personality of the person or a brand.) Looks like interesting stuff. You can find out more at http://tag.microsoft.com.

• Couldn't pass the signin screen on ubuntu

  I have an issue here with my computer using ubuntu 10.10 on a 64 bits machine. When I start it, I have the login screen, I enter my credentials but instead of starting the session it reloads the login screen again. I checked the disc using fsck and it seems clean. How should I proceed to diagnose and repair this issue? Thanks! [Edit] I went to the log files, this is what I got: auth.log pam_unix (gdm:session): session opened for user amokrane by (uid=0) pam_ck_connector (gdm:session): nox11 mode, ignoring PAM_TTY :0 pam_unix (gdm:session) :session closed for user amokrane messages.log No ACPI video bus found I also took a shot with my camera of the black screen that appears between the two login screens, it says something like: fsck from util-linux-ng 2.17.2 /dev/sdc4 : propre, xxxx files, xxxx blocs Starting AppArmor profiles Skipping profiles in /etc/apparmor.d/disable: usr.bin.firefox Setting sensors limits Starting postgreSQL ... /var/log/Xorg.0.log [ 25.375] (II) intel(0): Modeline "1920x1080"x60.0 172.80 ...

• System wide Proxy settings when on a windows network with a password

  - by sav

  I'm using Ubuntu on a windows network. I want to connect to the world wide web. I have followed the steps here which I have found very useful. However when I try to ping a website (eg: ping www.wikipedia.org) I get no reply. I can ping local computers on my network, but I need to go through our proxy to get to the world wide web. I can even browse wikipedia using firefox, I just needed to enter the proxy configuration script location and my username and password. I'm quite sure the reason I'm having this trouble is because I havn't entered a username and password. I'm not sure how to do this on a system wide level. ultimately I would like to be able to use package managers like synaptic but first I need them to be able to connect to the internet. EDIT As sugested I created a /etc/apt/apt.conf file like Acquire::http::Proxy "http://chrisav:[email protected]:8080"; Acquire::https::Proxy "https://chrisav:[email protected]:8080"; Acquire::ftp::Proxy "ftp://chrisav:[email protected]:8080"; Acquire::socks::Proxy "socks://chrisav:[email protected]:8080"; However I still cant ping wikipedia when I try installing stuff I get chris@chris-Ubuntu:~$ sudo apt-get install kate Reading package lists... Done Building dependency tree Reading state information... Done E: Unable to locate package kate
