  • How create a virtual network for practice?

    - by light
    I need to organize a virtual network for practice with Windows Server 2008 and several workstations with Windows OS. To make it all I only have a laptop with Dual-Core 2.10Ghz, 3 GB RAM, 50 GB free space and Windows 7 on it. Also I have external USB 3.0 hard-drive with 250GB free space and flash disk with 8GB space. What can you suggest? Because I have limited resources, I think to install ESXi 5.1 on the main disk of my laptop as second OS, with installed Windows 7. I have no idea will it work or not, but after that I want to try to create hosts using availible space on external hard-drive. Is it possible?

  • Consuming Hello World pagelet in WebCenter Spaces

    - by astemkov
    Introduction The goal of this exercise is to show you how can you use Hello World pagelet that you just created from your web space. Assumptions Let's assume the following: Pagelet Producer is running on http://pageletserver.company.com:8889/pagelets/ WebCenter is running on http://webcenter.company.com:8888/webcenter/ You created Hello_World pagelet as described here. For our exercise we will need a space created. So let's login into WebCenter Portal and create a space called "myspace" using "Portal Site" template: Registering Pagelet Producer with WebCenter portal In order to use our newly created pagelet from WebCenter Spaces, we first need to register Pagelet Producer: Click "Administraion" link on WebCenter toolbar Open the "Configuration" tab Click on "Services" link on the upper-left corner of the page Click on "Portlet Producers" link on the right hand pane of the screen Click on "Register" button Select "Pagelet Producer" radio button and type Producer Name = "MyPageletProducer" Server URL = http://pageletserver.company.com:8889/pagelets/ Click "Test" button If everything is succesful you will see the following screen: Now click "OK'. Pagelet producer is registered: Inserting Hello World pagelet to WebCenter Space Now let's insert Hello World pagelet into "myspace" page: Let's go back to "myspace", click on the icon in a upper-right corner of the page and select "Edit Page" Click on one of the "Add Content" buttons: Select "Mash-Ups": Select "Pagelet Producers: You will see the MyPageletProducer that we just registered: Click on it. You will see the library "MyLib" that contains our "Hello_World" pagelet. Click on "MyLib" and you will see "Hello_World" pagelet. Click on "Add" button, and then "Close" button. Click "Save" button, and then "Close". Now we see that our "Hello World" pagelet is inserted into "myspace" page:

  • Desktop icons disappears when Nautilus is launched, until next boot

    - by Santosh
    What happens: When I log in into my Ubuntu everything is normal, I have some icons on my desktop and I can see them at this point of time. As soon as I click on the explorer (nautilus) on the Launcher bar, everything goes (disappers) and never comes. No matter how many time you click on the launcher, you can't open nautilus. I tried opening nautilus from the terminal, get the following: santosh@santosh:~$ nautilus Initializing nautilus-gdu extension ** (nautilus:2158): DEBUG: SyncDaemon already running, initializing SyncdaemonDaemon object Initializing nautilus-open-terminal extension (nautilus:2158): Gtk-CRITICAL **: gtk_action_set_visible: assertion `GTK_IS_ACTION (action)' failed (nautilus:2158): Gtk-CRITICAL **: gtk_action_set_visible: assertion `GTK_IS_ACTION (action)' failed Segmentation fault I suspect on "Segmentation fault" on the last line, whats that? I was amazed when I run this command in sudo.: santosh@santosh:~$ sudo nautilus Initializing nautilus-gdu extension ** (nautilus:2216): DEBUG: Syncdaemon not running, waiting for it to start in NameOwnerChanged Initializing nautilus-open-terminal extension (nautilus:2216): Gtk-CRITICAL **: gtk_action_set_visible: assertion `GTK_IS_ACTION (action)' failed (nautilus:2216): Gtk-CRITICAL **: gtk_action_set_visible: assertion `GTK_IS_ACTION (action)' failed Nautilus-Share-Message: Called "net usershare info" but it failed: 'net usershare' returned error 255: net usershare: cannot open usershare directory /var/lib/samba/usershares. Error No such file or directory Please ask your system administrator to enable user sharing. As soon as I type sudo nautilus and hit enter, nautilus starts and the desktop background changes (to the default which ubuntu has). Don't know why but at this point as soon as I click on Desktop (from the left pane) then nautilus closes. Did anyone has same issue? I am corrently working with commandline to do my work and its a big pain. Additional Information: Another thing I have noticed that when I want to open the location of PDF file I am reading in document viewer (by clicking the folder icon). It gives error "Could not open the containing folder" and "Failed to execute child process "nautilus" (Permission denied)". Any idea?

  • Android SDK having trouble with ADB

    - by MowDownJoe
    So, I installed the Android SDK, Eclipse, and the ADT. Upon firing up Eclipse the first time after setting up the ADT, this error popped up: [2012-05-29 12:11:06 - adb] /home/drsmith/Downloads/android-sdk-linux/platform-tools/adb: error while loading shared libraries: libncurses.so.5: cannot open shared object file: No such file or directory [2012-05-29 12:11:06 - adb] 'adb version' failed! /home/drsmith/Downloads/android-sdk-linux/platform-tools/adb: error while loading shared libraries: libncurses.so.5: cannot open shared object file: No such file or directory [2012-05-29 12:11:06 - adb] Failed to parse the output of 'adb version': Standard Output was: Error Output was: /home/drsmith/Downloads/android-sdk-linux/platform-tools/adb: error while loading shared libraries: libncurses.so.5: cannot open shared object file: No such file or directory [2012-05-29 12:11:06 - adb] /home/drsmith/Downloads/android-sdk-linux/platform-tools/adb: error while loading shared libraries: libncurses.so.5: cannot open shared object file: No such file or directory [2012-05-29 12:11:06 - adb] 'adb version' failed! /home/drsmith/Downloads/android-sdk-linux/platform-tools/adb: error while loading shared libraries: libncurses.so.5: cannot open shared object file: No such file or directory [2012-05-29 12:11:06 - adb] Failed to parse the output of 'adb version': Standard Output was: Error Output was: /home/drsmith/Downloads/android-sdk-linux/platform-tools/adb: error while loading shared libraries: libncurses.so.5: cannot open shared object file: No such file or directory I'm not quite sure how this is.

  • Cannot FTP without simultaneous SSH connection?

    - by Lucas
    I'm trying to set up an old box as a backup server (running 10.04.4 LTS). I intend to use 3rd party software on my PC to periodically connect to my server via FTP(S) and to mirror certain files. For some reason, all FTP connection attempts fail UNLESS I'm simultaneously connected via SSH. For example, if I use putty to test the connection to port 21, the system hangs and times out. I get: 220 Connected to LeServer USER lucas 331 Please specify the password. PASS [password] <cursor> However, when I'm simultaneously logged in (in another session) everything works: 220 Connected to LeServer USER lucas 331 Please specify the password. PASS [password] 230 Login successful. Basically, this means that my software will never be able to connect on its own, as intended. I know that the correct port is open because it works (sometimes) and nmap gives me: Starting Nmap 5.00 ( http://nmap.org ) at 2012-03-20 16:15 CDT Interesting ports on xx.xxx.xx.x: Not shown: 995 closed ports PORT STATE SERVICE 21/tcp open ftp 22/tcp open ssh 53/tcp open domain 139/tcp open netbios-ssn 445/tcp open microsoft-ds Nmap done: 1 IP address (1 host up) scanned in 0.15 seconds My only hypothesis is that this has something to do with iptables. Maybe it's allowing only established connections? I don't think that's how I set it up, but maybe? Here's my iptables rules for INPUT: lucas@rearden:~$ sudo iptables -L INPUT Chain INPUT (policy DROP) target prot opt source destination fail2ban-ssh tcp -- anywhere anywhere multiport dports ssh ufw-before-logging-input all -- anywhere anywhere ufw-before-input all -- anywhere anywhere ufw-after-input all -- anywhere anywhere ufw-after-logging-input all -- anywhere anywhere ufw-reject-input all -- anywhere anywhere ufw-track-input all -- anywhere anywhere ACCEPT tcp -- anywhere anywhere tcp dpt:ftp I'm using vsftpd.

  • Procedural... house with rooms generator

    - by pek
    I've been looking at some algorithms and articles about procedurally generating a dungeon. The problem is, I'm trying to generate a house with rooms, and they don't seem to fit my requirements. For one, dungeons have corridors, where houses have halls. And while initially they might seem the same, a hall is nothing more than the area that isn't a room, whereas a corridor is specifically designed to connect one area to another. Another important difference with a house is that you have a specific width and height, and you have to fill the entire thing with rooms and halls, whereas with a dungeon, there is empty space. I think halls in a house is something in between a dungeon corridor (gets you to other rooms) and an empty space in the dungeon (it's not explicitly defined in code). More specifically, the requirements are: There is a set of predefined rooms I cannot create walls and doors on the fly. Rooms can be rotated but not resized Again, because I have a predefined set of rooms, I can only rotate them, not resize them. The house dimensions are set and has to be entirely filled with rooms (or halls) I.e. I want to fill a 14x20 house with the available rooms making sure there is no empty space. Here are some images to make this a little more clear: As you can see, in the house, the "empty space" is still walkable and it gets you from one room to another. So, having said all this, maybe a house is just a really really tightly packed dungeon with corridors. Or it's something easier than a dungeon. Maybe there is something out there and I haven't found it because I don't really know what to search for. This is where I'd like your help: could you give me pointers on how to design this algorithm? Any thoughts on what steps it will take? If you have created a dungeon generator, how would you modify it to fit my requirements? You can be as specific or as generic as you like. I'm looking to pick your brains, really.

  • Looking for some OO design advice

    - by Andrew Stephens
    I'm developing an app that will be used to open and close valves in an industrial environment, and was thinking of something simple like this:- public static void ValveController { public static void OpenValve(string valveName) { // Implementation to open the valve } public static void CloseValve(string valveName) { // Implementation to close the valve } } (The implementation would write a few bytes of data to the serial port to control the valve - an "address" derived from the valve name, and either a "1" or "0" to open or close the valve). Another dev asked whether we should instead create a separate class for each physical valve, of which there are dozens. I agree it would be nicer to write code like PlasmaValve.Open() rather than ValveController.OpenValve("plasma"), but is this overkill? Also, I was wondering how best to tackle the design with a couple of hypothetical future requirements in mind:- We are asked to support a new type of valve requiring different values to open and close it (not 0 and 1). We are asked to support a valve that can be set to any position from 0-100, rather than simply "open" or "closed". Normally I would use inheritance for this kind of thing, but I've recently started to get my head around "composition over inheritance" and wonder if there is a slicker solution to be had using composition?

  • can anyone help me through the preparation of Eclipse IDE for android developer in ubuntu 12.04?

    - by csbl
    I'm new to to Linux, in this particular case, to Ubuntu. I have a small android project I have to finnish until this Friday and I'm still stuck with the install and preparing of the development envrironment. The only thing I did was install the Eclipse IDE. I'm still missing the SDK, JAVA and anything else that might be needed. Can someone help me through this? It's only because I'm running out of time to develop, or else I would embarc on a deeper investigation of this OS. I tried the step to install android platforms, through Eclispe-Help-Install New Software, and I got the follwoing error messages, at the end of the process: [2012-06-06 17:35:56 - adb] /home/catia/android-sdks/platform-tools/adb: error while loading shared libraries: libncurses.so.5: cannot open shared object file: No such file or directory [2012-06-06 17:35:56 - adb] 'adb version' failed! /home/catia/android-sdks/platform-tools/adb: error while loading shared libraries: libncurses.so.5: cannot open shared object file: No such file or directory [2012-06-06 17:35:56 - adb] Failed to parse the output of 'adb version': Standard Output was: Error Output was: /home/catia/android-sdks/platform-tools/adb: error while loading shared libraries: libncurses.so.5: cannot open shared object file: No such file or directory [2012-06-06 17:35:56 - adb] /home/catia/android-sdks/platform-tools/adb: error while loading shared libraries: libncurses.so.5: cannot open shared object file: No such file or directory [2012-06-06 17:35:56 - adb] 'adb version' failed! /home/catia/android-sdks/platform-tools/adb: error while loading shared libraries: libncurses.so.5: cannot open shared object file: No such file or directory [2012-06-06 17:35:56 - adb] Failed to parse the output of 'adb version': Standard Output was: Error Output was: /home/catia/android-sdks/platform-tools/adb: error while loading shared libraries: libncurses.so.5: cannot open shared object file: No such file or directory Can anyone help, please??

  • Getting MTP to work with a Galaxy tab 2 7.0?

    - by Wouter
    I'm trying to get MTP with the galaxy tab 2 7.0 working on my ubuntu installation. Such that I can access the files. I tried to do what is described here: http://www.omgubuntu.co.uk/2011/12/how-to-connect-your-android-ice-cream-sandwich-phone-to-ubuntu-for-file-access I however fail at executing one of the following commands mtp-detect | grep idVendor mtp-detect | grep idProduct This fails [20:42|0] $ mtp-detect | grep idVender Device 0 (VID=04e8 and PID=6860) is a Samsung GT-P7310/P7510/N7000/I9100/Galaxy Tab 7.7/10.1/S2/Nexus/Note. PTP_ERROR_IO: failed to open session, trying again after resetting USB interface LIBMTP libusb: Attempt to reset device LIBMTP PANIC: failed to open session on second attempt Unable to open raw device 0 [20:44|0] $ mtp-detect | grep idProduct Device 0 (VID=04e8 and PID=6860) is a Samsung GT-P7310/P7510/N7000/I9100/Galaxy Tab 7.7/10.1/S2/Nexus/Note. PTP_ERROR_IO: failed to open session, trying again after resetting USB interface LIBMTP libusb: Attempt to reset device LIBMTP PANIC: failed to open session on second attempt Unable to open raw device 0 Now my guess was was that the idVender is the same as the VID (04e8) and the idProduct is the same as PID (6860) Now I continued to work with those values and completed the tutorial. When finished I tried android-connect This returned fuse: bad mount point `/media/GalaxyTab': Transport endpoint is not connected Does anybody have a clue what to do? Also I want to note that when I connect my GalaxyTab 2 7.0 that I still get a pop-up of ubuntu that a device was connected. I also can still see the mapstructure, the problem however is is that all the folders have 0 bytes and do not have any subfolders. I can only see the folders in the root. ps. I also checked a similar question and tried what is described in this answer http://askubuntu.com/a/88630/27480

  • Formatting php, what works more efficiently?

    - by JamesM-SiteGen
    Hello fellow programmers, I was just wondering what makes php work faster, I have a few methods that I always go and do, but that only improves the way I can read it, but how about the interpreter? Should I include the curly braces when there is only one statement to run? if(...){ echo "test"; } # Or.. if(...) echo "test"; === Which should be used? I have also found http://beta.phpformatter.com/ and I find the following settings to be good, but are they? Indentation: Indentation style: {K&R (One true brace style)} Indent with: {Tabs} Starting indentation: [1] Indentation: [1] Common: [x] Remove all comments [x] Remove empty lines [x] Align assignments statements nicely [ ] Put a comment with the condition after if, while, for, foreach, declare and catch statements Improvement: [x] Remove lines with just a semicolon (;) [x] Make normal comments (//) from perl comments (#) [x] Make long opening tag (<?php) from short one (<?) Brackets: [x] Space inside brackets- ( ) [x] Space inside empty brackets- ( ) [x] Space inside block brackets- [ ] [x] Space inside empty block brackets- [ ] Tiny var names: often I go through my code and change $var1 to $a, $var2 to $b and so on. I do include comments at the start of the file to show to me what each letter(s) mean.. Final note: So am I doing the right thing with the curly braces and the settings? Are there any great tips that help it run faster?

  • importing animations in Blender, weird rotations/locations

    - by user975135
    This is for the Blender 2.6 API. There are two problems: 1. When I import a single animation frame from my animation file to Blender, all bones look fine. But when I import multiple (all of the frames), just the first one looks right, seems like newer frames are affected by older ones, so you get slightly off positions/rotations. This is true when both assigning PoseBone.matrix and PoseBone.matrix_basis. bone_index = 0 # for each frame: for frame_index in range(frame_count): # for each pose bone: add a key for bone_name in bone_names: # "bone_names" - a list of bone names I got earlier pose.bones[bone_name].matrix = animation_matrices[frame_index][bone_index] # "animation_matrices" - a nested list of matrices generated from reading a file # create the 'keys' for the Action from the poses pose.bones[bone_name].keyframe_insert('location', frame = frame_index+1) pose.bones[bone_name].keyframe_insert('rotation_euler', frame = frame_index+1) pose.bones[bone_name].keyframe_insert('scale', frame = frame_index+1) bone_index += 1 bone_index = 0 Again, it seems like previous frames are affecting latter ones, because if I import a single frame from the middle of the animation, it looks fine. 2. I can't assign armature-space animation matrices read from a file to a skeleton with hierarchy (parenting). In Blender 2.4 you could just assign them to PoseBone.poseMatrix and bones would deform perfectly whether the bones had a hierarchy or none at all. In Blender 2.6, there's PoseBone.matrix_basis and PoseBone.matrix. While matrix_basis is relative to parent bone, matrix isn't, the API says it's in object space. So it should have worked, but doesn't. So I guess we need to calculate a local space matrix from our armature-space animation matrices from the files. So I tried multiplying it ( PoseBone.matrix ) with PoseBone.parent.matrix.inverted() in both possible orders with no luck, still weird deformations.

  • Jumping with Mecanim synchronization

    - by Abhishek Deb
    I am using Unity3D 4.1 for one of my projects. I have a robot character which is always running. I am using mecanim animation system. What I really want:When I press Space bar, the character should jump up in the air, triggering an animation clip and then by the time it reaches the ground, the animation clip should also end. What actually is happening:When I press Space bar, the character jumps in the air. Animation clip plays as it should, but ends way before it reaches the ground. So, it looks like he is running in the mid air. What have I done: I have this humanoid robot setup with a jump animation bounded with the space bar key. Also, instead of using root motion, I am directly moving the robot from code. //Jumping if(Input.GetKeyDown(KeyCode.Space)){ rigidbody.AddForce(Vector3.up*jumpVelocty); anim.SetBool("Jump",true); } else anim.SetBool("Jump",false); Character's Details: Rigidbody = Mass:30, Freeze rotaion:x,y,z Capsule Collider = Material: metal, center(0,4.5,0), radius:1, height:11 Script = jumpVelocity:20000 Jump Animation Clip: ~ 2 seconds. I am really out of ideas how to synchronize everything. Should I make the character jump in some other way so that it quickly comes down and touches the ground to match the animation clip? If yes, please provide a direction.

  • If statement causing xna sprites to draw frame by frame

    - by user1489599
    I’m a bit new to XNA but I wanted to write a simple program that would fire a cannon ball from a cannon at a 45 degree angle. It works fine outside of my keyboard i/o if statement, but when I encapsulate the code around an if statement checking to see if the user hits the space bar, the sprite will draw one frame at a time every time the space bar is hit. This is the code in question if (currentKeyboardState.IsKeyUp(Keys.Space) && previousKeyboardState.IsKeyDown(Keys.Space) && !skullBall.Alive) { //works outside the keyboard input if statement //{ skullBall.Position = cannon.Position; skullBall.DeltaY = -(float)(Math.Sin(MathHelper.ToRadians(45)) * 50/*39.7577*/ * time + 0.5 * (gravity * (time * time))); skullBall.DeltaX = (float)(Math.Cos(MathHelper.ToRadians(45)) * 50/*39.7577*/ * time); skullBall.Alive = true; //} } The skull ball represents the cannon ball and the cannon is just the starting point. DeltaX and DeltaY are the values I’m using to update the cannon balls position per update. I know it's dumb to have the cannon ball start at the cannons position every time the update is called but it’s not really noticeable right now. I was wondering if after examining my code, if anyone noticed any errors that would cause the sprite to display frame by frame instead of drawing it as a full animation of the cannon ball leaving the cannon and moving from there.

  • Installing Ubuntu along with windows 7 on shrunk partition

    - by Thabo
    I am new to Ubuntu OS and ask Ubuntu community. First this is not a duplicate question. Actually this a question which is a summery of all solutions and questions were posted in this community, related to Install Ubuntu along with Windows 7. I have bought a new Hp laptop with its original windows 7.I want to install Ubuntu along with windows 7 64 bit. I ran the Ubuntu 12.4 Desktop installation CD. But Ubuntu installer doesn't show the "along with windows 7 option"only it is showing two options. I read some questions and answers posted on this community. Specially following link Ubuntu 12.04 does not see windows already install on my computer (dual installation) I tried following thinks, I ran the terminal in live CD and tried sudo dmraid -rE command and dmraid remove command .But terminals says there is no dmraid partitions. So I tried another scenario checked my partitions with g parted.There are some partitions labeled C,HP tools,Recovery and System. C is containing windows 7 Files. So I shrank the volume of C Drive. Now I have 50000Mb of unallocated disk. I tried with Gparted to create a partition on that allocated space.It says some thing that you can't create more than four primary partition.Of course all other four partitions were created on widows are actually type of primary partition. So I went back to Windows 7 and tried to create a new volume on unallocated space.But unfortunately it says,If i create a new volume it will be the type of Dynamic partition.It says we cant boot another OS from that partition. So i cancelled that step. Now i have 50000Mb unallocated space but how can i install Ubuntu on that partition without harming the existing Windows 7? Because still I have only two options: Erase and install Ubuntu. Try something else. (I can see my unallocated space by going to "something else" option.)

  • Office arangement - comfort vs. teamwork?

    - by finrod
    Our team works in an open-space office. Luckily the cubicles are quite big (L shaped tables for everyone!), there is quite a lot of space so we are not sandwiched. Without going into further detail, there are comfortable spots (window), normal spots and stupid spots (near the corridor). Until recently, the development team of twelve engineers was seated so that all types of spots were occupied and we were all close together. In the old arrangement, verbal communication was very easy - half of the team was withing talking distance. The other half was like ten steps away. Often times I could ask, discuss, solve problems without leaving the cube. Most of the communication is work related, no bullshit or mental masturbation that would unnecessarily distract others. Now we have moved to another part of the building and have larger space to occupy. At this point, everyone could pick their spot. Naturally all stupid spots are left empty (for the poor newcomers to occupy bwehaha). In the new arrangement, the development team is stretched across the floor and some of the key engineers are seated 'far' from each other - definitely not within talking distance. I have yet to experience how this works out but am getting concerned that team work and communication may have been traded for personal comfort. Finally the questions... What do you think is better office arrangement? Such that allows for free verbal communication but trading for some developer's comfort, or such that potentially hinders verbal communication but makes developer's more comfortable in their spot? Or maybe it does not matter at all and we will evolve to be efficient in any arrangement? What is your personal experience? Note - yes I read books and posts how workplace is important in our job. However in this case - we are all still in open space and the difference between the different spots are not really groundbreaking. So I'm thinking the little comfort that few developers gain is not worth the loss of easy communication.

  • Determine All SQL Server Table Sizes

    Im doing some work to migrate and optimize a large-ish (40GB) SQL Server database at the moment.  Moving such a database between data centers over the Internet is not without its challenges.  In my case, virtually all of the size of the database is the result of one table, which has over 200M rows of data.  To determine the size of this table on disk, you can run the sp_TableSize stored procedure, like so: EXEC sp_spaceused lq_ActivityLog This results in the following: Of course this is only showing one table if you have a lot of tables and need to know which ones are taking up the most space, it would be nice if you could run a query to list all of the tables, perhaps ordered by the space theyre taking up.  Thanks to Mitchel Sellers (and Gregg Starks CURSOR template) and a tiny bit of my own edits, now you can!  Create the stored procedure below and call it to see a listing of all user tables in your database, ordered by their reserved space. -- Lists Space Used for all user tablesCREATE PROCEDURE GetAllTableSizesASDECLARE @TableName VARCHAR(100)DECLARE tableCursor CURSOR FORWARD_ONLYFOR select [name]from dbo.sysobjects where OBJECTPROPERTY(id, N'IsUserTable') = 1FOR READ ONLYCREATE TABLE #TempTable( tableName varchar(100), numberofRows varchar(100), reservedSize varchar(50), dataSize varchar(50), indexSize varchar(50), unusedSize varchar(50))OPEN tableCursorWHILE (1=1)BEGIN FETCH NEXT FROM tableCursor INTO @TableName IF(@@FETCH_STATUS<>0) BREAK; INSERT #TempTable EXEC sp_spaceused @TableNameENDCLOSE tableCursorDEALLOCATE tableCursorUPDATE #TempTableSET reservedSize = REPLACE(reservedSize, ' KB', '')SELECT tableName 'Table Name',numberofRows 'Total Rows',reservedSize 'Reserved KB',dataSize 'Data Size',indexSize 'Index Size',unusedSize 'Unused Size'FROM #TempTableORDER BY CONVERT(bigint,reservedSize) DESCDROP TABLE #TempTableGO Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors?

  • Using 12.04 installation as a persistent pen drive

    - by Cawas
    Disclaimer: I aim to build a self contained pen drive with my application inside, so no matter about updates. Maybe I'm looking at the wrong linux distribution to do this... Please let me know if you think so. I've tried knoppix and even lubuntu, but they don't come with enough "drivers" for Unity3D to work. Creating a custom live persistent pen drive is a real pain and I'm trying for 1 day without any success. Sure, being able to do it would probably be ideal and occupy the minimum space. Using the installation image on a pen drive, however, is good enough and is really easy to create. We can even do it from any OS, using UNetBootin, LiLi USB Creator or some other methods. Straight forward. Some recommend installing it on a pen drive. But that requires a lot of space and, I believe, it won't behave as good as something meant to be installed on a usb disk, because of memory management. So, there are only a few negative points on using the installation image that I can think of. Question here, is how to remove those drawbacks: Having to press "Try Ubuntu". That's the big one. Couldn't find how. Unable to load everything on memory and keep on running without the pen drive (like this) Unable to remove "Install Ubuntu 12.04 LTS" app. Setting the ISO to use maximum amount of space for the OS will leave pen drive with zero space left and any file saved within it from ubuntu is inaccessible from the outside (when plugin the pen drive and not booting from it). Am I missing something? Can those points be fixed?

  • Launching LibreOffice Files - Unusual Window Behaviour

    - by Mike
    Ubuntu 11.10 Unity. If I launch LibreOffice Files (ODS, ODT, ODP) with a double click in their home folders they launch with the appropriate application (Calc, Writer, Impress) however the application windows do not display the usual Close, Minimize, Restore buttons in the left hand corner. There is just a blank space where they should be. In the Unity launcher on the left there is not the expected white arrow next to the launcher icon and the open app is not seen by the ALT+TAB keystroke when you have multiple windows open. For example: if you have an app open in this way and say Firefox, if you minimize Firefox you are only left with the desktop and you have no way to locate the open LibreOffice app. Clicking the app's icon in the launcher simply opens another instance. A messy workaround is to click [Firefox] to a restored window and the LibreOffice app can be seen behind it allowing a mouse click to bring it forward. If I open the LibreOffice app from the launcher and then Open a file from its menu, it all behaves as expected. I don't find this as convenient; anyone know how to fix the bad behaviour?

  • Strange resizing of partition after reinstalling Ubuntu 14.04 64bit

    - by Mike
    I started with Windows 7 on 120GB SSD and Ubuntu 14.04 32bit installed on 60GB partition on separate 1TB HDD. I just did a fresh reinstall of 14.04 64bit on the 1TB HDD. In the installation set up process, I selected the second choice of "deleting Ubuntu 14.04 and all it's files,documents, photos etc and reinstalling" to what I figured would reinstall the 64bit OS on the already existing 60GB allocated partition. Instead, it reinstalled Ubuntu as 43.5 GB and created a separate 15.8 partition. So now it reads that my disk space for Ubuntu ( in settingsdetails) is 43.5GB (instead of the previous 60GB that my old 32bit had) The upside is I can now access my 1TB HDD from my toolbar(and all the files located on it) Before, I could only access that through Windows (I can also access the SSD too, but that was always the case) Both drives are mounted now. My initial reaction was to go into Windows 7 disk management delete the strange/new 15gb partitionextend the 43.5 to the unallocated space. But I'm not sure if this is necessary or would even work. My question is why did it create a 15gb partition shrinking my ubuntu disk space, and is it useful? I don't want wasted space, so before I go through all my set up of Ubuntu, should I change this. At this time my HDD reads as 43.5 partiton, 15.8 partition, and 874GB exfat32 (939GB total)

  • Abstract Factory Method and Polymorphism

    - by Scotty C.
    Being a PHP programmer for the last couple of years, I'm just starting to get into advanced programming styles and using polymorphic patterns. I was watching a video on polymorphism the other day, and the guy giving the lecture said that if at all possible, you should get rid of if statements in your code, and that a switch is almost always a sign that polymorphism is needed. At this point I was quite inspired and immediately went off to try out these new concepts, so I decided to make a small caching module using a factory method. Of course the very first thing I have to do is create a switch to decide what file encoding to choose. DANG! class Main { public static function methodA($parameter='') { switch ($parameter) { case 'a': $object = new \name\space\object1(); break; case 'b': $object = new \name\space\object2(); break; case 'c': $object = new \name\space\object3(); break; default: $object = new \name\space\object1(); } return (sekretInterface $object); } } At this point I'm not really sure what to do. As far as I can tell, I either have to use a different pattern and have separate methods for each object instance, or accept that a switch is necessary to "switch" between them. What do you guys think?

  • More efficient in range checking

    - by Mob
    I am going to use a specific example in my question, but overall it is pretty general. I use java and libgdx. I have a ship that moves through space. In space there is debris that the ship can tractor beam in and and harvest. Debris is stored in a list, and the object contains it own x and y values. So currently there is no way to to find the debris's location without first looking at the debris object. Now at any given time there can be a huge (1000+) amount of debris in space, and I figure that calculating the distance between the ship and every single piece of debris and comparing it to maximum tractor beam length is rather inefficient. I have thought of dividing space into sectors, and have each sector contain a list of every object in it. This way I could only check nearby sectors. However this essentially doubles memory for the list. (I would reference the same object so it wouldn't double overall. I am not CS major, but I doubt this would be hugely significant.) This also means anytime an object moves it has to calculate which sector it is in, again not a huge problem. I also don't know if I can use some sort of 2D MAP that uses x and y values as keys. But since I am using float locations this sounds more trouble than its worth. I am kind of new to programming games, and I imagined there would be some eloquent solution to this issue.

  • GlassFish and JavaEE Roadmap Update

    - by Tori Wieldt
    As announced at JavaOne, GlassFish Server Open Source Edition 4.1 is scheduled for 2014. ?Oracle is planning updates as needed to GlassFish Server Open Source Edition, which is commercially unsupported?. Oracle has announced the following updates to the GlassFish roadmap: The trunk will eventually transition to GlassFish Server Open Source Edition 5 as a Java EE 8 implementation. ?The Java EE 8 Reference Implementation will be derived from GlassFish Server Open Source Edition 5. This replicates what has been done in past Java EE and GlassFish Server releases. Oracle will no longer release future major releases of Oracle GlassFish Server with commercial support – specifically Oracle GlassFish Server 4.x with commercial Java EE 7 support will not be released.?Commercial Java EE 7 support will be provided from WebLogic Server. Oracle GlassFish Server will not be releasing a 4.x commercial version.   Oracle is committed to the future of Java EE. Java EE 7 has been released and planning for Java EE 8 has begun. GlassFish Server Open Source Edition continues to be the strategic foundation for Java EE reference implementation going forward. The primary role of GlassFish Server Open Source Edition has been, and continues to be, driving adoption of the latest release of the Java Platform, Enterprise Edition.  For more information, read Java EE and GlassFish Server Roadmap Update blog on the The Aquarium.

  • How do I automatically start Clamz with AMZ files for Amazon MP3 downloads?

    - by Takkat
    Chromium can open downloaded files with the default application (e.g. PDF in Evince). In my setup a downloaded .AMZ (for Amazon MP3) always opened with Gedit. However I would like to have all downloaded .amz files to autromatically open with Clamz, a command line tool for downloading that works like a charm. As in Nautilus my .amz files were associated to open with Gedit too I thought it was a good idea to add a clamz.desktop file in ~/.local/share/applications (according to this answer) [Desktop Entry] Encoding=UTF-8 Name=Clamz Comment=Open AMZ files for Amazon MP3 download Exec=/usr/bin/clamz %u Terminal=True Type=Application Icon= Categories=Application; StartupNotify=true MimeType=audio/x-amzxml; NoDisplay=true This lets me choose Clamz as default application in Nautilus. But when opening an .amz file in Nautilus it still does not open with Clamz as expected but is treated as an executable text file instead (note that the executable bit is not set!). Is there any other way to make Chromium or Nautilus always open an .amz file with Clamz? Did I miss to change setting in another place?
