• App installed in ~/usr launches from terminal but not Applications menu (or why does setting ld_library_path in .profile not work as it should)

  - by levesque

  I have built and installed an application under a directory of my choosing, let's say under /home/jim/usr, so files have been put in three-four folders, all under this $HOME/usr folder (e.g., bin, include, lib, share, etc.). I can launch this application from the command line just fine as I added the proper paths to my environement variables PATH and LD_LIBRARY_PATH in ~/.bashrc. I added the same paths to the ~/.profile file, which, if I'm not mistaken, is supposed to be parsed by Ubuntu. Doesn't work. Nothing. Where can I go from there? EDIT: I logged out/in and restarted my computer. Both didn't change a thing. The problem seems to come from the fact that no matter what I do the LD_LIBRARY_PATH environment variable is not properly passed to Ubuntu. Using log files, I found that the application I'm trying to run in this example doesn't find one it's dependencies located in ~/usr/lib. One solution would be to add the /home/jim/usr/lib folder inside a file located in /etc/ld.so.conf.d/, but I don't have admin rights on this machine. Making a wrapper script like this one works: #!/bin/bash export LD_LIBRARY_PATH=$HLOC/usr/lib application &> $HOME/application_messages.log but that would force me to wrap all my home compiled applications with this script. Any ideas? Why does Ubuntu/Gnome remove the LD_LIBRARY_PATH environment variable from my set variables? Is it because trying to do this is bad practice? UPDATE (and solution): As found by Christopher, there is a bug report about this on launchpad. LD_LIBRARY_PATH is unset after parsing of the ~/.profile file. See the bug report. Seems the only solution for now is to make a wrapper script.

• How to design a scriptable communication emulator?

  - by Hawk

  Requirement: We need a tool that simulates a hardware device that communicates via RS232 or TCP/IP to allow us to test our main application which will communicate with the device. Current flow: User loads script Parse script into commands User runs script Execute commands Script / commands (simplified for discussion): Connect RS232 = RS232ConnectCommand Connect TCP/IP = TcpIpConnectCommand Send data = SendCommand Receive data = ReceiveCommand Disconnect = DisconnectCommand All commands implement the ICommand interface. The command runner simply executes a sequence of ICommand implementations sequentially thus ICommand must have an Execute exposure, pseudo code: void Execute(ICommunicator context) The Execute method takes a context argument which allows the command implementations to execute what they need to do. For instance SendCommand will call context.Send, etc. The problem RS232ConnectCommand and TcpIpConnectCommand needs to instantiate the context to be used by subsequent commands. How do you handle this elegantly? Solution 1: Change ICommand Execute method to: ICommunicator Execute(ICommunicator context) While it will work it seems like a code smell. All commands now need to return the context which for all commands except the connection ones will be the same context that is passed in. Solution 2: Create an ICommunicatorWrapper (ICommunicationBroker?) which follows the decorator pattern and decorates ICommunicator. It introduces a new exposure: void SetCommunicator(ICommunicator communicator) And ICommand is changed to use the wrapper: void Execute(ICommunicationWrapper context) Seems like a cleaner solution. Question Is this a good design? Am I on the right track?

• (GUIDE) How to install and configure Mariadb on Ubuntu 12.10+

  - by Myh Yazid

  First of all open terminal and type this sudo apt-get install python-software-properties I recommend you to use MariaDB version 10.0.4 Alpha because when im installed it i've got no errors compare with 5.5 version. 2: Put this commands in terminal sudo apt-get install software-properties-common sudo apt-key adv --recv-keys --keyserver hkp://keyserver.ubuntu.com:80 0xcbcb082a1bb943db sudo add-apt-repository 'deb http://download.nus.edu.sg/mirror/mariadb/repo/10.0/ubuntu quantal main' If you're using other version please change the "quantal" to your ubuntu version codename eg : 13.10 saucy 13.04 raring 12.10 quantal (im using this version) 12.04 precise` 3: Type in this commands sudo apt-get update sudo apt-get install mariadb-server 4: after finished installed mariadb you need to run this sudo mysql_install_db sudo /usr/bin/mysql_secure_installation If have problem consider look at the end of this post for solution 5: You're done!! Problems solving In step 3 if you get problem, like unmet dependencies, Go to /etc/apt/preferences.d then create new file called "mariadb" Then,Consider to put the below code in the mariadb file that you just created Package: * Pin: origin <mirror-domain> Pin-Priority: 1000 In step 4 you may get 2 errors first occur when you run sudo mysql_install_db Solution : open another terminal and do this killall mysqld 2.second eror may occur when you running sudo /usr/bin/mysql_secure_installationcommand Solution : try doing this cd /etc/init.d and try run ./mysqld start if ./mysqld doesnt exists use ./mysql start as in my case That's All Thank you for reading. I wrote this based on my experience installing this.Any errors you get community here can help you if i cant..tq .

• Kanji characters appear as boxes

  - by s3d10s

  i'm having trouble with the display of japanese characters on Windows 8 Pro (English, 64-bit, updated regularly). They appear as boxes (picture) in windows explorer, windows menus (even in the language settings of control panel), iTunes and nearly everywhere else, besides web browsers. I was using windows 7 until now, and it didn't have any of these problems, and i'm using the same applications now, as i was using in windows 7. Sometimes (!) when i restart the machine the problem goes away, but that isn't a real solution. What i've tried so far: added japanese language to windows of course installed/uninstalled/reinstalled japanase language pack (didn't have any impact though) i've read in one of these superuser topics a possible solution, when i had to create a txt file on the desktop with a kanji in the filename - that also didn't work (but i honestly hope that hacking and tweaking an operation system released in 2012 can't be the solution to display kanjis..) Please give me any ideas, i'm a bit hopeless here, and don't want to spend my life installing operation systems..

• Securely automount encrypted drive at user login

  - by Tom Brossman

  An encrypted /home directory gets mounted automatically for me when I log in. I have a second internal hard drive that I've formatted and encrypted with Disk Utility. I want it to be automatically mounted when I login, just like my encrypted /home directory is. How do I do this? There are several very similar questions here, but the answers don't apply to my situation. It might be best to close/merge my question here and edit the second one below, but I think it may have been abandoned (and therefore never to be marked as accepted). This solution isn't a secure method, it circumvents the encryption. This one requires editing fstab, which necessitates entering an additional password at boot. It's not automatic like mounting /home. This question is very similar, but does not apply to an encrypted drive. The solution won't work for my needs. Here is one but it's for NTFS drives, mine is ext4. I can re-format and re-encrypt the second drive if a solution requires this. I've got all the data backed up elsewhere.

• Linear Performance Scalability with HP San Solutions

  - by Berzemus

  Hi all, I need a San Solution with linear scalability in size as well as in performance. From what I know, with a Modular Smart Array solution such as the P2000/MSA-class solutions from HP, even with a dual controller initial node, I can only increase the size of it, as added nodes come controller-less, so overall performance tends to decrease. On the other hand, the P4000 (lefthand) family of solutions has each of it's nodes have it's own controller, and so when a node is added, storage capacity as well as performance increase. Am I right in all that I say, and is the P4000 the only solution, or have I forgotten something ?

• Revolutionizing Digital Commerce

  - by bwalstra

  The confluence of the Internet, the pace of change in technology, and the demands of the value-conscious consumer are accelerating the evolution of the global digital marketplace at an unprecedented rate. Success in the new digital economy has become inextricably linked with the agility to launch innovative products, services, and new business models efficiently with minimal risk. A major obstacle to agility, and by extension to success in digital commerce, is the fact that by and large information technology (IT) infrastructure is tightly coupled with particular business models. Enterprises, through well intentioned but misconstrued costsaving belief, continue to customize existing infrastructure and create now silos to support new business models. In reality, this approach results in rigid, inflexible business processes and exposes the enterprise to unnecessary risks, higher opportunity costs, and lower profit margins. Oracle, a leading supplier of business solutions to the enterprise, is enabling the business strategies necessary to succeed in the digital economy by offering a modern, open, modular, and functionally comprehensive revenue management solution that decouples IT infrastructure from business models. Enterprises using the Oracle solution are able to focus on core competencies and innovate unimpeded, assuring that business and IT systems will seamlessly adapt to changing conditions of the digital economy.

• Script/tool to import series of snapshots, each being a new revision, into Subversion, populating source tree?

  - by Rob

  I've developed code locally and taken a fairly regular snapshot whenever I reach a significant point in development, e.g. a working build. So I have a long-ish list of about 40 folders, each folder being a snapshot e.g. in ascending date YYYYMMDD order, e.g.:- 20100523 20100614 20100721 20100722 20100809 20100901 20101001 20101003 20101104 20101119 20101203 20101218 20110102 I'm looking for a script to import each of these snapshots as a new subversion revision to the source tree. The end result being that the HEAD revision is the same as the last snapshot, and other revisions are as numbered. Some other requirements: that the HEAD revision is not cumulative of the previous snapshots, i.e., files that appeared in older snapshots but which don't appear in later ones (e.g. due to refactoring etc.) should not appear in the HEAD revision. meanwhile, there should be continuity between files that do persist between snapshots. Subversion should know that there are previous versions of these files and not treat them as brand new files within each revision. Some background about my aim: I need to formally revision control this work rather than keep local private snapshot copies. I plan to release this work as open source, so version controlling would be highly recommended I am evaluating some of the current popular version control systems (Subversion and GIT) BUT I definitely need a working solution in Subversion. I'm not looking to be persuaded to use one particular tool, I need a solution for each tool I am considering as I would also like a solution in GIT (I will post an answer separately for GIT so separate camps of folks who have expertise in GIT and Subversion will be able to give focused answers on one or the other). The same question but for GIT: Script/tool to import series of snapshots, each being a new edition, into GIT, populating source tree? An outline answer for Subversion in stackoverflow.com but not enough specifics about the script: what commands to use, code to check valid scenarios if necessary - i.e. a working script basically. http://stackoverflow.com/questions/2203818/is-there-anyway-to-import-xcode-snapshots-into-a-new-svn-repository

• How to open a page in Chrome from the command line, in a new tab or an existing tab as appropriate?

  - by MattH

  I'm looking for a way to open a given page in Google Chrome from the command line, with the following behaviour: If the given page is already open in a tab, navigate to that tab If the given page is not already open in a tab, open the page in a new tab and show that tab Currently when I open a URL from the command line (e.g. using "open http://godzillahaiku.tumblr.com" on Mac OS X), Chrome will always open the URL in a new tab. I end up with lots of duplicate tabs as a result, which is a minor annoyance. I'm looking for a solution that works on Mac OS X, but a non-OS specific solution would be preferable. I'd consider writing a Chrome extension for this if there's no existing solution.

• Which tool / technology: System management for databases and dependent services

  - by Filburt

  I'm looking for advice on how to enable our team to take down and re-start our company systems for maintainance purposes. The scenario includes several Oracle db machines several MS SQL Server machines with multiple instances windows services (IIS etc.) BizTalk EAI solution Apache and Tomcat instances lots of scheduled tasks on win2003 and win2008 machines (physical and virtual). The main focus is on capture all dependencies between said databases and services and tasks connecting to them. At the moment an enterprise class solution is not an option. We are considering developing a solution driven by PowerShell scripts but I hope for some more suggestions.

• Group Matchmaking

  - by Simon Kérouack

  Consider different groups(1 or more players) queuing together, we want to make 2 opposing teams containing each the same amount of players while keeping the groups together. At the same time we want to make both teams' average ranking as close as possible. Now also consider we have as a working set the subset of groups currently queuing within a given ranking range. For an example, let's say we have the following groups, ordered by queuing time: Id, playerCount, totalRank, avgRank 0, 3, 126, 42 1, 2, 60, 30 2, 1, 25, 25 3, 2, 80, 40 4, 1, 40, 40 5, 1, 20, 20 6, 3, 150, 50 for this specific subset, the expected output should ideally be: team1: 0, 1 (total: 186) team2: 2, 5, 6 (total: 195) up to now the solution I have been using is to balance out each team by making each team pick the group with highest ranking within the subset turn by turn. The team who picks is the one with the currently lowest average rank unless one is already full. If one team is already full the other team tries to complete itself with groups that would make the rank gap as small as possible. This solution turns out to have issues with frequent edge cases and I'm looking for a better solution, or some fine-tuning that could be made. In most cases, players seems to want teams of 5 people and queue in group of 2. Our average subset when 2 teams of 5 are chosen is made of about 14 players if that may be of any help.

• Efficient coding in Visual Studio (or another IDE), with touch typing

  - by cheeesus

  Moving the cursor to another position in code is one of the most frequent actions when coding. I don't write my programs from the beginning to the end, like a letter. However, moving the cursor requires me to move my right hand to the key arrows or to the mouse, which feels like an interruption to my writing rhythm, since I'm using touch typing. I want my hands to rest on the keyboard. It's difficult to explain what I mean, but I think every coder using touch typing knows what I mean. I tried many things, like defining some shortcuts as surrogate arrow keys (Shift+Alt+J, K, L, I), or buying a keyboard with a Trackpoint, Trackpad, or Trackball on it, but I have not yet found a satisfying solution to the problem. What is the best solution you know of, regardless of which IDE you use? Edit: Thank you for your answers. I am using a lot of shortkeys, but I think using a Vim plugin in Visual Studio would interfere too much with the shortkeys I am used to. Also, I have a keyboard with a built-in mouse, but I'm still looking for a better solution.

• Open source system for swipe card access?

  - by Moduspwnens

  We're looking at replacing our campus-wide magnetic swipe card system with something more robust. The "programmer" side of me says there's got to be an open-source, scalable solution that already does this, but all I've been able to find are proprietary vendor-specific solutions. Ideally, it'd have the following: Based on some open standard that allows us to select from a wide selection of card readers (like IMAP or HTTP) Support different kinds of card access (magnetic strip, RFIDs, etc.) Future-proof (to the extent possible) The lack of information I'm finding leads me to believe I'm not searching for the right things... or such a solution doesn't exist. Is there not some basic, open-source solution to this (like MySQL for databases, or Moodle for an LMS, or Apache for a web server)?

• Power User - archive Outlook mail items into SQL Server

  - by marc_s

  I am looking (and so far not finding any) for a solution to archive e-mail items from my Outlook into SQL Server. My PST is beginning to get really really big, and I'd love to extract my older e-mail into SQL Server in a way so I can still easily find mails if needed. I would prefer SQL Server as the storage medium since I'm familiar with it, and it's rock solid - I don't want to have a collection of PST files or CHM files or anything like that. Does anyone know of such a solution? I'm a power/home user - I can't afford $5'000 enterprise licenses - I need a sub-$100 solution for private use.

• Reusing Web Forms across BPM Roles

  - by Mona Rakibe

  Recently Varsha(another BPM Product Manager) approached me with a requirement where she wanted to reuse same Web Form for different task activity.We both knew this is easily achievable.The human task outcomes can differ to distinguish the submission based on roles.Her requirement was slightly more than this, she wanted to hide some data based on the logged in user. If you have worked on Web Form rules, dynamically showing and hiding data is common requirement and easily achievable using Form Rules. In this case the challenge was accessing BPM role inside the Web Form. Although, will be addressing this requirement in future release she wanted a immediate solution(Aha, after all customers are not the only one's who can not wait). Thankfully we managed to come-up with a solution and I hope this will be helpful to larger audience. Solution has 3 steps : Step 1: We added a hidden attribute in our form (Role). The purpose of this attribute is just to store the current logged in user's role and we pass the value during data association. Step 2 : In your data association step, pass the role value based on the Swimlane Step 3 : Now use this hidden attribute value in your Web Form rule for dynamic behavior Detailed steps and sample can be downloaded from Java.net.

• How to structure my GUI agnostic project?

  - by Nezreli

  I have a project which loads from database a XML file which defines a form for some user. XML is transformed into a collection of objects whose classes derive from single parent. Something like Control - EditControl - TextBox Control - ContainterControl - Panel Those classes are responsible for creation of GUI controls for three different enviroments: WinForms, DevExpress XtraReports and WebForms. All three frameworks share mostly the same control tree and have a common single parent (Windows.Forms.Control, XrControl and WebControl). So, how to do it? Solution a) Control class has abstract methods Control CreateWinControl(); XrControl CreateXtraControl(); WebControl CreateWebControl(); This could work but the project has to reference all three frameworks and the classes are going to be fat with methods which would support all three implementations. Solution b) Each framework implementation is done in separate projects and have the exact class tree like the Core project. All three implementations are connected using a interface to the Core class. This seems clean but I'm having a hard time wrapping my head around it. Does anyone have a simpler solution or a suggestion how should I approach this task?

• Modern open source NIDS/HIDS and consoles?

  - by MattC

  Years back we set up an IDS solution by placing a tap in front of our exterior firewall, piping all the traffic on our DS1 through an IDS box and then sending the results off to a logging server running ACiD. This was around 2005-ish. I've been asked to revamp the solution and expand on it and looking around, I see that the last release of ACiD was from 2003 and I can't seem to find anything else that seems even remotely up-to-date. While these things may be feature complete, I worry about library conflicts, etc. Can anyone give me suggestions for a Linux/OpenBSD based solution using somewhat modern tools? Just to be clear, I know that Snort is still actively developed. I guess I'm more in the market for a modern open-source web console to consolidate the data. Of course if people have great experiences with IDS' other than Snort I'm happy to hear about it.

• Empty interface to combine multiple interfaces

  - by user1109519

  Suppose you have two interfaces: interface Readable { public void read(); } interface Writable { public void write(); } In some cases the implementing objects can only support one of these but in a lot of cases the implementations will support both interfaces. The people who use the interfaces will have to do something like: // can't write to it without explicit casting Readable myObject = new MyObject(); // can't read from it without explicit casting Writable myObject = new MyObject(); // tight coupling to actual implementation MyObject myObject = new MyObject(); None of these options is terribly convenient, even more so when considering that you want this as a method parameter. One solution would be to declare a wrapping interface: interface TheWholeShabam extends Readable, Writable {} But this has one specific problem: all implementations that support both Readable and Writable have to implement TheWholeShabam if they want to be compatible with people using the interface. Even though it offers nothing apart from the guaranteed presence of both interfaces. Is there a clean solution to this problem or should I go for the wrapper interface? UPDATE It is in fact often necessary to have an object that is both readable and writable so simply seperating the concerns in the arguments is not always a clean solution. UPDATE2 (extracted as answer so it's easier to comment on) UPDATE3 Please beware that the primary usecase for this is not streams (although they too must be supported). Streams make a very specific distinction between input and output and there is a clear separation of responsibilities. Rather, think of something like a bytebuffer where you need one object you can write to and read from, one object that has a very specific state attached to it. These objects exist because they are very useful for some things like asynchronous I/O, encodings,...

• Word 2007 "Out of Memory or Disk Space" Error on launch.

  - by Adam

  Word 2007 is installed on a Vista Home Premium machine and whenever it starts up it opens what appears to be a dynamic installer to do something and then throws up the "Out of Memory or Disk Space" error. Word 2007 never completes starting up. Reinstalling Word hasn't helped and if I can avoid reinstalling Windows until Windows 7 is released and get Word working in the mean time, that would be ideal. I've been looking around for a solution, once of which seemed to point to a problem with the user account. I created a second user on the machine and Word still had the same problem. The other solution that seems possible is a corrupted normal.dot/normal.dotm file. However, even in the location it should be, I can't seem to find it. Am I going in the right direction with this? Is there another solution I haven't come across that will fix this? If it is possible that renaming normal.dot/normal.dotm how can I find it?

• D3DXMatrixDecompose gives different quaternion than D3DXQuaternionRotationMatrix

  - by Fraser

  In trying to solve this problem, I tracked down the problem to the conversion of the rotation matrix to quaternion. In particular, consider the following matrix: -0.02099178 0.9997436 -0.008475631 0 0.995325 0.02009799 -0.09446743 0 0.09427284 0.01041905 0.9954919 0 0 0 0 1 SlimDX.Quaternion.RotationMatrix (which calls D3DXQuaternionRotationMatrix gives a different answer than SlimDX.Matrix.Decompose (which uses D3DXMatrixDecompose). The answers they give (after being normalized) are: X Y Z W Quaternion.RotationMatrix -0.05244324 0.05137424 0.002209336 0.9972991 Matrix.Decompose 0.6989997 0.7135442 -0.03674842 -0.03006023 Which are totally different (note the signs of X, Z, and W are different). Note that these aren't q/-q (two quaternions that represent the same rotation); they face completely different directions. I've noticed that with matrices for rotations very close to that one (successive frames in the animation) that the Matrix.Decompose version gives a solution that flips around wildly and occasionally goes into the desired position, while the Quaternion.RotationMatrix version gives solutions that are stable but go in the wrong direction. This is only for the right arm in my animation -- for the left arm, both functions give the correct solution, which is the same quaternion within error tolerances. This makes me think that there's some sort of numeric instability or weird stuff with signs going on. I tried implementing this and then this, but both gave me a completely incorrect solution (even for the matricies where the SlimDX ones were working correctly) -- maybe the rows and columns are flipped?

• How to avoid game objects accidentally deleting themselves in C++

  - by Tom Dalling

  Let's say my game has a monster that can kamikaze explode on the player. Let's pick a name for this monster at random: a Creeper. So, the Creeper class has a method that looks something like this: void Creeper::kamikaze() { EventSystem::postEvent(ENTITY_DEATH, this); Explosion* e = new Explosion; e->setLocation(this->location()); this->world->addEntity(e); } The events are not queued, they get dispatched immediately. This causes the Creeper object to get deleted somewhere inside the call to postEvent. Something like this: void World::handleEvent(int type, void* context) { if(type == ENTITY_DEATH){ Entity* ent = dynamic_cast<Entity*>(context); removeEntity(ent); delete ent; } } Because the Creeper object gets deleted while the kamikaze method is still running, it will crash when it tries to access this->location(). One solution is to queue the events into a buffer and dispatch them later. Is that the common solution in C++ games? It feels like a bit of a hack, but that might just be because of my experience with other languages with different memory management practices. In C++, is there a better general solution to this problem where an object accidentally deletes itself from inside one of its methods?

• Password Manager that can sync a Blackberry and Mac OSX.

  - by pdhoven

  I use a Blackberry Bold and a Macbook Pro. I am looking for a solution to have a synchronized password manager between the two devices. All the commercial ones I have discovered won't work between a Blackberry and a Mac. The almost solution was KeePass. I like the application on the Blackberry but I could not get the sync working reliably to the Mac. As well, I had to run the PC application by using Mono on the Mac and it was pretty slow. I am happy to pay for a good solution.
