• Lock screen elements frozen on desktop

  - by user286968

  I have finally made the switch from Windows to Ubuntu and now have to ask the first question because search did not help me this time. (Please help me in a newb-friendly way) The problem is easily described: The elements shown in the lockscreen on boot (ubuntu logo in the middle and watermark in bottom left corner) stay there even when I'm entering desktop. How can I remove them again? They haven't been there in the first place, but after updating Ubuntu with Update Center, the problem occured. As I cant post an image here with my reputation, pls see this link: http://s30.postimg.org/age8fraww/Screenshot_from_2014_05_30_23_27_58.jpg Thanks for your help and time. Kind regards

• how to serialize function depending on what instance of object calls it, if same instance call in a thread then do serialize else not

  - by LondonDreams

  I have a function which fetches and updates some record from db and I am trying to make sure each if the function is called by same instance of object(same Or different thread) then function should behave synchronized else its a call from different object instance function need not to be synchronized. I have tried it use a lock per client. That is, instead of synchronizing the method directly using explicit locking through lock objects using Map. function is like :- getAndUpdateMyHitCount(myObjId){ //go to db and get unique record by myObjId //fetch value , increment , save update } And this function may get call is same thread by different Or same object instance But as fetching and matching from Map is slow , Is there other optimized way to do this ? Found similar at this Question but dont feel that is optimized

• Can Layer Masks Achieve This Effect

  - by Julian

  If you look at the image below you will see the player surrounded by a dotted yellow box. The dotted yellow box is also part of the player and represented a portion of the player being masked from both rendering and affected by physics. My question is if layer masks in Unity can achieve the following effect. -In Area 1, the red box/animations of the player are visible and the rigidbody of this shape is affected by all Physics. -Any portion of the player that enters Area 2 makes the larger yellow box within the area become visible (and affected by physics) and vice versa for any portion of the smaller red box that enters. -This can persist when both entering and leaving either area from any direction. Thank you for any help!

• How do I disable the upgrade to new version warning? [duplicate]

  - by Anatoliy

  This question already has an answer here: Disable Ubuntu Update Manager's new version warning 2 answers After I allowed Ubuntu on my notebook to upgrade to 13.4, it lost Wi-Fi connection. Network menu does not show wireless access points, but according to syslog it establishes connection. Also, the wireless router provides IP address to the host. I don't want to spend time on debugging and solving the problem that most probably will reappear with new update, so I decided to reinstall 12.10 version. It recognized Broadcom Wi-Fi modem right after the boot, and everything went great, until today I powered it on and suddenly found that it is running 13.4 and all my problems are back! Is it possible to instruct it to stay with 12.10 until I decide to upgrade?

• What technology(s)would be suitable for the front end part of a Java web game?

  - by James.Elsey

  As asked in a previous question, I'm looking to create a small MMO that will be deployed onto GAE. I'm confused about what technologies I could use for the user interface, I've considered the following JSP Pages - I've got experience with JSP/JSTL and I would find this easy to work with, it would require the user having to "submit" the page each time they perform an action so may become a little clumsey for players. Applet - I could create an applet that sits on the front end and communicates to the back end game engine, however I'm not sure how good this method would be and have not used applets since university.. What other options do I have? I don't have any experience in Flash/Flex so there would be a big learning curve there. Are there any other Java based options I may be able to use? My game will be text based, I may use some images, but I'm not intending to have any animations/graphics etc Thanks

• Need suggestions on what you regard as &ldquo;security&rdquo;

  - by John Breakwell

  I’m currently writing a large piece on MSMQ security and wanted to check I was covering the right areas. I have some doubts as I’ve seen the occasional MSMQ forum question where a poster has used the word “security” in different contexts to what I was expecting. So here are the areas I plan to cover: Message security encryption on the wire (SSL and IPSEC) encryption of the message (MSMQ encryption) encryption of the payload (data encryption) signing and authentication Queue security SIDs and ACLs Discoverability Cross-forest issues Storage security NTFS permissions unencrypted data Service security Ports and Firewalls DOS attacks Hardened mode (HTTP only) RPC secure channel requirement authenticated RPC requirement Active Directory object permissions Setup Administrator requirements What else would you want to see?

• How much data validation is too much? [closed]

  - by adbertram

  Possible Duplicate: Data input validation - Where? How much? I'm a new PHP developer and am into Powershell quite a bit but this question is language agnostic. I've been questioning my code quite a bit lately thinking about how many nets I should setup to catch exceptions, verify results, etc. I realize that I could go crazy trying to verify each and every line of code but at the same time I want the code as resilient as possible. I'm not talking about user input but verifying output from methods. Is there some standard or rule of thumb to go by when deciding when and where to do data validation?

• Buy the server contents

  - by user103475

  How i can buy the contents of the server of archive.ubuntu.com (for lucid lynx)? In my country i have ultra slow connection. It will take years for downloading all these gigabytes. Because, canonical will stop supporting ubuntu 10.04, i want all the files now, before it's too late. i know that all files will be transfer to old.dir but i think some will be lost. And anyway i want the files. My question is: Can canonical provide (with payment) a disk with the contents of the server? Cheers

• Why Gsettings isn't enough to reset my nautilus settings?

  - by berdario

  I'm trying to narrow down a bug (to eventually report it or give up if it'll turn out that resetting a simple setting will be enough to get rid of it) I noticed that with a brand new user the bug doesn't pop up so I tried to reset the config of my user's nautilus I renamed .config/nautilus I renamed .nautilus2 (strange name... why the 2?) and I did a gsettings reset-recursively org.gnome.nautilus strangely enough, it didn't work: I previously set up to use my home as the desktop folder, and now the key has correctly been resetted $gsettings get org.gnome.nautilus.preferences desktop-is-home-dir false and yet on my desktop I see the contents of my home folder (meaning that the settings have not been resetted) I know that with the transition to gtk3 there've been lots of changes (before I should've used gconf... but now there's dconf and gsettings), so there're quite a bit of question about nautilus... but these unfortunately now seem to be outdated

• Installing programs from a download

  - by user7274

  Hello, my name is Anthony and I'm new to Ubuntu and any other Linux OS for that matter. My question concerns downloading a program, and then installing it. The program is called Remotedroid, it lets you use your phone as a wireless keyboard and mouse. I'm use to windows automatically starting setup upon download and cant figure out how to initiate the install in Ubuntu. The programs website says its compatible with Linux OS and the readme file says to just click the extension remotedroidserver.jar to use, but it wont work and none of the files do anything. I've unzipped all the files and my Java is all up to date as far as i know, I think. I'm just not getting how to run a setup in Ubuntu. I looked around this site for the answer but came up with nothing so if someone could maybe offer some insight I would be grateful. Thank you.

My first question is - Is it possible to use ethernet for synergy and keep using wifi for all other application. If the answer is yes, can somebody please guide me how to achieve this. Thanks,

• Retrieve the coordinates of the *occluding* (closest/drawn) pixels during 3D overlap, using OpenGL?

  - by Big Rich

  Hi, Sorry if the question is not worded well, I'm a new to both 3D and OpenGL. How could I go about obtaining the 3D coordinates of the occluding object, at the point where occlusion is happening (i.e. the 'intersection' of the object in front/closest to the screen)? Just to offer a [very] rudimentary, visual, example, if you were to form an index-finger cross, with your right hand closest to your face, I'd like to know the coordinates of the part of your right finger which obscures the other finger (obviously back within the OpenGL context - no jokers ;-) ). If there is a way to find out both about the occluder (hider) and the occluded (hidden) objects in OpenGL, then that would be of great use, also. Cheers Rich

• Why do so many people dislike C++?

  - by General K

  Beginners and professional, on blogs, in forums and chatrooms - people say it everywhere: C++ oh dear god no The short form of the question: For what reason is C++ so widely disliked and people are horrified by the imagination of using it for some project? I have been using a lot of different languages, including C++ by now, and I can only say that I really like it. I'm far more horrified by Delphi than by C++. Actually, I find it's an almost perfect, compiled language! I've been doing a lot of different projects in C++ as well, ranging from 3D video games to webservers and emulators for old video game consoles. And I still do not see the problem everyone else seems to have with it! It was hard for me to get into it of course, as it is quite complex and has a lot of depth, but after that it's simply great.

• Jquery/JavaScript's role in MVC (zend)

  - by user7543288

  I have my doubts if this question should have went into the programmers.stackexchange.com or not…but I would like to ask all you experienced developers out there, how do you see the connection that jquery - javascript has with the MVC. How would you explain it to a n00b? does it bridge the communication between the View and the Controller? or what? I have done my research and I believe this is the best article explaining it http://www.alistapart.com/articles/javascript-mvc/ but I would like to hear your point of view..

• Are there any reliable solutions for annotations/reflection/code-metadata in C?

  - by dukeofgaming

  Not all languages support java-like annotations or C#-like attributes or code metadata in general, however that doesn't mean it is not possible to have in languages that don't have this. An example is PHP with Stubbles and the Doctrine annotation library. My question is, is there anything like this for C?, or are there any reliable ways of doing reflection with extended code metadata in C? Ideally, I'm looking for something that reads javadoc-like comments. Edit: The reason for me *needing* as opposed to just wanting, is that I need to generate C code and code-metadata from a database, as well as being able to edit that metadada and update the database. The volume of the work (~15,000 variables/structures/functions to generate from this database) justifies the solution.

• How can I stay focused and motivated on a project?

  - by RTS

  I'm working on starting my own software development business, but I've noticed that I have major issues getting projects out by their deadlines, and in general getting them out of the "almost-done" stage. I feel my problem is that I like complex programming too much, and I end up rewriting code to make it cleaner/more efficient/less error prone as a means of putting off more "boring" development. I end up with polished applications at the end, but I spend twice as long on the project as I should have. If I ever want my company to succeed, I need to work on staying focused on what actually needs to be done, so the question is: What techniques do you use to keep yourself focused and motivated on a project, in your career?

• Difference between '\n' and '\r\n'

  - by sukhbir

  Yes yes, I am aware that '\n' writes a newline in UNIX while for Windows there is the two character sequence: '\r\n'. All this is very nice in theory, but my question is why? Why the carriage return character is extra in Windows? If UNIX can do it in \n why does it take Windows two characters to do this? I am reading David Beazley's Python book and he says: For example, on Windows, writing the character '\n' actually outputs the two- character sequence '\r\n' (and when reading the file back, '\r\n' is translated back into a single '\n' character). Why the extra effort? I will be honest. I have known the difference for a long time but have never bothered to ask WHY. I hope that is answered today. Thanks for your time.

• How well supported is the ATI graphics on a Sony VAIO SA?

  - by whoami

  This is the first time i will be buying a laptop/desktop to use as a Ubuntu platform with ATI. Now i did notice a while back that ATI drivers were not in cahoots with Linux as of yet. I am just wondering if any one is still experiencing ATI issues, or this is no longer the case. I am looking to spend money on a laptop Upgrade, but I don't want to spend a screw load of money just to find out I can only use windows and my Graphics driver does not work. So the Question is: What's ATI Support like on Ubuntu 10.10 Here is what im thinking of buying http://www.gadgetfreak.gr/wp-content/uploads/2011/02/SB_S08_keyboard_B_us_FP-1024x716.jpg, If any one has the Sony VAIO SA Series and installed Ubuntu on it, please do share your story, about driver problems. On a side note my old Sony S-Series which im using now, i never got the fingerprint reader or the webcam working on it, has any one been able to do this for the new models? I preferably dont care about the fingerprint reader but do care about the webcam.

• What do you use to create sprite graphics? [closed]

  - by SimpleRookie

  Possible Duplicate: What tools do you use for 2D art/sprite creation? What do you folks suggest for creating sprite graphics and sprite sheets? I fiddle with pixelformer and tilestudio. Pixelfromer has a kicken interface, it is quick and easy to make graphics, but a bit cumbersom if you want to make a spritemap. Tile Studio is a interesting mix or tiles and maps, but it is a bit buggy and basic. The Adobe series, just don't really seem to handle tiny graphics well. (there is a previous posting of this question existing, but it is a year old and I was hoping for further/updated input from the community)

• Domain Model and Querying

  - by Tyrsius

  I am new to DDD, having worked only in Transaction-Script apps with an anemic model, or just Big Balls of Mud, so please forgive any terminology I abuse. I am trying to understand the proper separation between the domain model and the repository. What is the proper way to construct a domain object that is coming from a database, assuming the (incredibly simplified) need to query for objects by status (returns enumerable), or by ID. Should a factory be building the objects, exposing methods for GetByStatus() and GetByID(), using a DIed repository? Should a repository be called directly, knowing how to build a domain model from the DTO? Should the domain model have a constructor for get by ID, using a DIed repoistory to load the initial state, using some other (?) method for the list? I am not really sure what the best way would be, and this question has an answer advocating each one (these are certainly mutuallu exclusive).

• DDD: service contains two repository

  - by tikhop

  Does it correct way to have two repository inside one service and will it be an application or domain service? Suppose I have a Passenger object that should contains Passport (government id) object. I am getting Passenger from PassengerRepository. PassengerRepository create request to server and obtain data (json) than parse received data and store inside repository. I have confused because I want to store Passport as Entity and put it to PassportRepository but all information about password contains inside json than i received above. I guess that I should create a PassengerService that will be include PassengerRepository and PassportRepository with several methods like removePassport, addPassport, getAllPassenger and etc. UPDATE: So I guess that the better way is represent Passport as VO and store all passports inside Passenger aggregate. However there is another question: Where I should put the methods (methods calls server api) for management passenger's passport. I think the better place is so within Passenger aggregate.
