  • How to properly diagram lambda expressions or traversals through them in Architecture Explorer?

    - by MainMa
    I'm exploring a piece of code in Architecture Explorer in Visual Studio 2010 to study the relations between methods. I noticed a strange behavior. Take the following source code. It generates a hello message based on a template and a template engine, the template engine being a method (a sort of strategy pattern simplified at a maximum for demo purposes). public string GenerateHelloMessage(string personName) { return this.ApplyTemplate( this.DefaultTemplateEngine, this.GenerateLocalizedHelloTemplate(), personName); } private string GenerateLocalizedHelloTemplate() { return "Hello {0}!"; } public string ApplyTemplate( Func<string, string, string> templateEngine, string template, string personName) { return templateEngine(template, personName); } public string DefaultTemplateEngine(string template, string personName) { return string.Format(template, personName); } The graph generated from this code is this one: Change the first method from this: public string GenerateHelloMessage(string personName) { return this.ApplyTemplate( this.DefaultTemplateEngine, this.GenerateLocalizedHelloTemplate(), personName); } to this: public string GenerateHelloMessage(string personName) { return this.ApplyTemplate( (a, b) => this.DefaultTemplateEngine(a, b), this.GenerateLocalizedHelloTemplate(), personName); } and the graph becomes: While semantically identical, those two versions of code produce different dependency graphs, and Architecture Explorer shows no trace of the lambda expression (while Visual Studio's code coverage, for example, shows them, as well as Code analysis seems to be able to understand that the link exists). How would it be possible, without changing the source code, to: Either force Architecture Explorer to display everything, including lambda expressions, Or make it traverse lambda expressions while drawing a dependency through them (so in this case, drawing the dependency from GenerateHelloMessage to DefaultTemplateEngine in the second example)?

  • Game-a-Week One

    - by Matt Christian
    Anyone who chats with me on a semi-regular basis knows I am absolutely horrible at completing something from beginnning to end.  Often times I'll begin something, lose interest at some point, and end up moving onto the next thing.  For example, I have 1/2 a full game created, 1/3 of a novel written, and half of a model set created.  Needless to say, unless I have some sort of pressure to finish something I don't stick to it. Recently however one of my online buddies challenged me to create a simple game.  The start date was last Thursday and the final game needed to be delivered by this next Sunday (giving me just over a week).  However, I am going out of town this Friday so will need to deliver it by Thursday, giving me exactly 1 week to develop a game.  Here is what the game needed to include: The player should be able to shoot Shooting things should score points Sounds very simple, but given a single week to produce all art assets plus the game isn't an easy task.  So far I've developed: An animated Main Menu that loads via script files, allows the user to start a new game or exit the game The game is 3D and the player can move around the play area with an 'over-the-shoulder' camera HUD elements are drawn to display the player's current score When the player presses Esc they are shown a pause menu where they can resume the game by pressing Esc again, or quit the game by pressing Space There are also 2 items implemented that don't work perfectly: JigLibX physics library implementation On the main menu there is an arrow symbol that rotates to always point at your mouse I've got 2 days of development left so hopefully I can get collision working, some of the art cleaned up, and some more of the camera functionality working.  Also, I'll need to take some time to package the game up which hopefully shouldn't take too long.

  • Input not supported message when monitor is powered off then back on

    - by Jason Down
    I've been getting a message on my monitor where "Input not supported" is floating around. This only happens when I manually turn the monitor off and then later turn it back on. Leaving the monitor on and allowing it to go to the screen saver doesn't seem to cause the issue (but I prefer to turn the monitor off if I'm going to be away from the computer for any length of time). Any ideas what might cause this, only when the monitor is turned off manually?

  • Cropped thumbnails in WordPress

    - by codethief
    Quote from Wordpress' image editor: The thumbnail image can be cropped differently. For example it can be square or contain only a portion of the original image to showcase it better. Here you can select whether to apply changes to all image sizes or make the thumbnail different. This is exactly what I'd like to do, except for the fact that I don't want Wordpress to scale it down to 150x150 pixels (or another predefined resolution). I'd just like to display a cropped (and therefore smaller) version of the picture which is then linked to the (uncropped) original. I also tried to set the thumbnails' width and height to 0 in the preferences. Then, however, I don't even get the chance to assign a cropped version as thumbnail in the editor. Could you tell me how to achieve that? Or isn't it possible at all?

  • Google Chrome not rendering webpages correctly

    - by sumit_gt
    I am facing some serious web page rendering issues with Chrome. It is more prominent during javascript based animations and stuff on websites like youtube. I have tried removing chrome using (sudo apt-get purge google-chrome-stable) and then reinstalling it. But the problems still persist. The same webpages work correctly on firefox on ubuntu and chrome on windows. The problem only shows up when I use chrome on ubuntu. I think the issue has started after I updated to the latest version of Chrome. I have used Chrome previously on this machine without any problems. I have attached a image that demonstrates the issue. What could possibly be the problem? PS: here's the output of lshw -c video: *-display description: VGA compatible controller product: Madison [Radeon HD 5000M Series] vendor: Hynix Semiconductor (Hyundai Electronics) physical id: 0 bus info: pci@0000:01:00.0 version: 00 width: 64 bits clock: 33MHz capabilities: pm pciexpress msi vga_controller bus_master cap_list rom configuration: driver=fglrx_pci latency=0 resources: irq:46 memory:e0000000-efffffff memory:f0020000-f003ffff ioport:d000(size=256) memory:f0000000-f001ffff Here's the output of lspci -nn: output of lspci -nn

  • Office jukebox systems

    - by jonayoung
    We're looking for a good office jukebox solution where staff can select songs via a web interface to be played over the central set of speakers. Must haves: Web Interface RSS / easy to scrap display of currently playing songs Ability to play mp3s and manage an ordered playlist. Good cataloguing of media. Multiple OSs supported as clients - Windows, Mac, Fedora Linux (will probably be accomplished by virtue of a web interface). We have tried XBMC which worked well as a proof of concept however the web interface is just too immature and has too many bugs for a reliable multi-user solution. I believe the same will be true of boxee. Nice to have: Ability to play music videos onto a monitor Ability to listen to radio streams specifically Shoutcast and the BBC. Ability to run on Linux is a nice to have but windows solutions which worked well would certainly be considered. I am aware of question 61404 and don't believe this to be a duplicate due to the specific requirements.

  • Automated texture mapping

    - by brandon
    I have a set of seamless tiling textures. I want to be able to take an arbitrary model and create a UV map with these properties: No stretching (all textures tile appropriately so there is no stretching and sheering of the texture) The textures display on the correct axis relative to the model it's mapping to (if you look at the example, you can see some of the letters on the front are tilted, the y axis of the texture should be matching up with the y axis of the object. Some other faces have upside down letters too) the texture is as continuous as possible on the surface of the model (if two faces are adjacent, the texture continues on the adjacent face where it left off) the model is closed (all faces are completely enclosed by other faces) A few notes. This mapping will occur before triangulation. I realize there are ways to do this by hand and it's probably a hard problem to automatically map textures in general, but since these textures are seamless and I just need uniform coverage it seems like an easier problem. I'm looking for an algorithmic approach to this that I can apply in general, not a tool that does it. What approach would work for this, is there an existing one? (I assume so)

  • HDMI video output not working for external monitor

    - by user291852
    I have installed from scratch ubuntu GNOME 14.04 with gnome-flashback on my old HP HDX 16 laptop (core 2 duo p8600 + nvidia GT9600M + 4GB of ram) and I have problems with the HDMI output (I use it to extend my desktop on a dell U2412M 1920x1200 monitor). In the following I summarize the configurations that I have tried: Using the open source nouveau drivers, only the laptop monitor works, no signal from the external monitor connected to the HDMI output. However, the output of the xrandr command show that the HDMI output is connected with the correct resolution 1920x1200 (I find this thing really weird). Nouveau drivers with VGA connection works without problems on the external monitor, but the image is blurry compared to the HDMI connection. Using the nvidia drivers (I have tried different versions: nvidia-331-updates and the xorg-edgers versions nvidia-334 and nvidia-337) the HDMI output works, but I have system instabilities, random crashes and display freezes. I can't even enter in terminal mode with ctrl-alt-f1, so I have to manually shut down the laptop with the power button. I really would like to use the HDMI output with the nouveau drivers to avoid the system instabilities that I experienced with the nvidia drivers, but I can't figure out how to make it works.

  • How can I install Celtx 2.9.7 properly on Ubuntu 12.04 LTS?

    - by cruxfilm
    I am new to Ubuntu and Linux and I want to install and use the newest version of the screenwriting software Celtx on Ubuntu 12.04 LTS. After trying https://answers.launchpad.net/ubuntu/+source/ubiquity/+question/206295 and using sudo add-apt-repository ppa:dreamstudio/video sudo apt-get update sudo apt-get install celtx I unfortunately had to find out that was a rather old version with a fairly screwed up UI. I then downloaded the newest version from http://download.celtx.com/2.9.7/Celtx-2.9.7-64.tar.bz2 but now I don't know how to properly install it. I extracted it to /home/username/ (there was no ~/bin/) as described here and I can now launch the application by running the file celtx within that folder (I get asked whether I want to Display, run or run it in Terminal) and it works fine. But I can't get it to launch from Unity. I tried right-clicking the launcher button and going "Lock to Launcher" while it's running and it does create an icon but clicking it to launch the program does nothing. Also searching for celtx in the Dash doesn't find the app. And advice on how to properly install Celtx 2.9.7 in Ubuntu 12.04 LTS?

  • Xubuntu 14.04 with Compton, strange screen tearing, only when playing videos though (advice needed)

    - by LinuxDudester
    Hello beloved community, Yet again I am in need of your great expertise. I ran into a very strange issue and just can't wrap my mind around it. I'm running Xubuntu 14.04 exclusively, with Compton installed. The OS runs great and I have absolutely no screen tearing when I move my windows around, scroll in my web browser, work in Gimp or Photoshop (wine) or even when I play very graphic demanding games, like Metro Last Light, Euro Truck Driver 2 and so on. There's not a tiny bit of tearing to see, but as soon as I play videos, in xbmc, vlc or parole media player the tearing begins (strangely enough this does not apply to youtube videos). I followed all available workarounds on askubuntu and the ubuntu forum,like the 50-xserver-command.conf, startx /etc/X11/Xsession /usr/bin/xbmc-standalone -- -bs or libsdl1.2debian fix and many more, but to no avail. I also tried the Open Source Nouveau display drivers as well, but for some odd reason they don't work so great on my system or at least with my graphics card. Even with Compton installed and configured, I have an extreme amount of screen tearing, as soon as I switch to the proprietary Nvidia drives the screen tearing is gone completely, except for the video playback with xbmc, vlc or parole media player. System info for your reference: OS: Xubuntu 14.04 Linux-x86_64 - Processor: Intel Core i7-4770S CPU @ 3.10GHz - Ram: 16 GB - GeForce GT 750M 1024 MB - Nvidia Driver: 331.38 Has anyone experienced such an odd issue or do you have any advice on how I could fix this? I would appreciate any help! Have a nice day!

  • Redmine + Backlogs not working on Turnkey Linux (Ubuntu)

    - by Riddler
    I'm trying to get Redmine + Backlogs work, so for starters I took a virtual appliance with Redmine from Turnkey Linux (http://www.turnkeylinux.org/redmine) and installed Backlogs on top of it, following the installation instructions (http://www.redminebacklogs.net/en/installation/ - used method #2). It seems to have installed ok, but when I go to the "Backlogs" tab and attempt to create some stories, this is what I get - first shows some kind of error/warning icon, others continue to display "in progress" icon indefinitely (can't post a screenshot, unfortunately, but you can take a look at it here: http://www.redmine.org/attachments/5329/Backlogs.jpg). None of the stories get actually created - leaving this tab and returning back to it shows empty backlogs. So.. what am I doing wrong, and how to fix this?

  • OOP concept: is it possible to update the class of an instantiated object?

    - by Federico
    I am trying to write a simple program that should allow a user to save and display sets of heterogeneous, but somehow related data. For clarity sake, I will use a representative example of vehicles. The program flow is like this: The program creates a Garage object, which is basically a class that can contain a list of vehicles objects Then the users creates Vehicles objects, these Vehicles each have a property, lets say License Plate Nr. Once created, the Vehicle object get added to a list within the Garage object --Later on--, the user can specify that a given Vehicle object is in fact a Car object or a Truck object (thus giving access to some specific attributes such as Number of seats for the Car, or Cargo weight for the truck) At first sight, this might look like an OOP textbook question involving a base class and inheritance, but the problem is more subtle because at the object creation time (and until the user decides to give more info), the computer doesn't know the exact Vehicle type. Hence my question: how would you proceed to implement this program flow? Is OOP the way to go? Just to give an initial answer, here is what I've came up until now. There is only one Vehicle class and the various properties/values are handled by the main program (not the class) through a dictionary. However, I'm pretty sure that there must be a more elegant solution (I'm developing using VB.net): Public Class Garage Public GarageAdress As String Private _ListGarageVehicles As New List(Of Vehicles) Public Sub AddVehicle(Vehicle As Vehicles) _ListGarageVehicles.Add(Vehicle) End Sub End Class Public Class Vehicles Public LicensePlateNumber As String Public Enum VehicleTypes Generic = 0 Car = 1 Truck = 2 End Enum Public VehicleType As VehicleTypes Public DictVehicleProperties As New Dictionary(Of String, String) End Class NOTE that in the example above the public/private modifiers do not necessarily reflect the original code

  • How to visualize timer functionality in sequence diagram?

    - by truthseeker
    I am developing software for communication with external device through serial port. To better understand the new functionality I am trying to display it in sequence diagram. Flow of events is as follows. I send to the device command to reset it. This is asynchronous operation so there is some delay between request and response (typically 100 ms). There can be case when the answer never comes (for example device is not connected to the specified port or is currently turned off). For this purpose I create a timer with period twice the maximum answer time. In my case it is 2 * 125 ms = 250 ms. If the answer comes in predefined time interval, I destroy already running timer. If the answer doesnt come in predefined interval, timer initiates some action. After this action we can destroy it. How to effectively model this situation in sequence diagram? Addendum 1: Based on advices made by scarfridge i drew following UML diagram. Comment by Ozair is also helpful for simplifying the diagram even more.

  • Telerik Releases a new Visual Entity Designer

    Love LINQ to SQL but are concerned that it is a second class citizen? Need to connect to more databases other than SQL Server? Think that the Entity Framework is too complex? Want a domain model designer for data access that is easy, yet powerful? Then the Telerik Visual Entity Designer is for you. Built on top of Telerik OpenAccess ORM, a very mature and robust product, Teleriks Visual Entity Designer is a new way to build your domain model that is very powerful and also real easy to use. How easy? Ill show you here. First Look: Using the Telerik Visual Entity Designer To get started, you need to install the Telerik OpenAccess ORM Q1 release for Visual Studio 2008 or 2010. You dont need to use any of the Telerik OpenAccess wizards, designers, or using statements. Just right click on your project and select Add|New Item from the context menu. Choose Telerik OpenAccess Domain Model from the Visual Studio project templates. (Note to existing OpenAccess users, dont run the Enable ORM wizard or any other OpenAccess menu unless you are building OpenAccess Entities.) You will then have to specify the database backend (SQL Server, SQL Azure, Oracle, MySQL, etc) and connection. After you establish your connection, select the database objects you want to add to your domain model. You can also name your model, by default it will be NameofyourdatabaseEntityDiagrams. You can click finish here if you are comfortable, or tweak some advanced settings. Many users of domain models like to add prefixes and suffixes to classes, fields, and properties as well as handle pluralization. I personally accept the defaults, however, I hate how DBAs force underscores on me, so I click on the option to remove them. You can also tweak your namespace, mapping options, and define your own code generation template to gain further control over the outputted code. This is a very powerful feature, but for now, I will just accept the defaults.   When we click finish, you can see your domain model as a file with the .rlinq extension in the Solution Explorer. You can also bring up the visual designer to view or further tweak your model by double clicking on the model in the Solution Explorer.  Time to use the model! Writing a LINQ Query Programming against the domain model is very simple using LINQ. Just set a reference to the model (line 12 of the code below) and write a standard LINQ statement (lines 14-16).  (OpenAccess users: notice the you dont need any using statements for OpenAccess or an IObjectScope, just raw LINQ against your model.) 1: using System; 2: using System.Linq; 3: //no need for anOpenAccess using statement 4:   5: namespace ConsoleApplication3 6: { 7: class Program 8: { 9: static void Main(string[] args) 10: { 11: //a reference tothe data context 12: NorthwindEntityDiagrams dat = new NorthwindEntityDiagrams(); 13: //LINQ Statement 14: var result = from c in dat.Customers 15: where c.Country == "Germany" 16: select c; 17:   18: //Print out the company name 19: foreach (var cust in result) 20: { 21: Console.WriteLine("CompanyName: " + cust.CompanyName); 22: } 23: //keep the consolewindow open 24: Console.Read(); 25: } 26: } 27: } .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: consolas, "Courier New", courier, monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; } Lines 19-24 loop through the result of our LINQ query and displays the results. Thats it! All of the super powerful features of OpenAccess are available to you to further enhance your experience, however, in most cases this is all you need. In future posts I will show how to use the Visual Designer with some other scenarios. Stay tuned. Enjoy!

  • IBus client for GNU Emacs: Installed, but how do I start it?

    - by fred.bear
    Having recently moved to Linux/Ubuntu, I'm looking for a good editor, and GNU Emacs seems to fit the bill. One thing I want from a text editor is the ability to handle Unicode Input Method Editors in a "normal way", across the board. For Ubuntu, the "normal way" is via IBus. However, emacs does not support IBus "off the shelf". I found a launchpad project: IBus client for GNU Emacs: ibus-el. I've installed ibus-el and set it up as per the Customize section of this emacswiki IBusMode page. I included the suggested "toggle" keybinding: ;; Use s-SPC to toggle input status It seems to have installed okay, but I have no idea how to invoke IBus and switch IMEs. s-SPC doesn't fire up the IBus language panel... I'm stuck :( ...so close, yet so far.... Here are the startup *messages* Loading 00debian-vars... No /etc/mailname. Reverting to default...

  • Tinkerforge Rotation/LCD & JavaFX Plans

    - by Geertjan
    The first time I integrated two Tinkerforge bricklets, the day before yesterday, was pretty cool: import com.tinkerforge.BrickMaster; import com.tinkerforge.BrickletLCD20x4; import com.tinkerforge.BrickletRotaryPoti; import com.tinkerforge.IPConnection; import java.util.Calendar; public class TFConnectionDemo { private static final String HOST = "localhost"; private static final int PORT = 4223; private static final String MASTERBRICKUID = "somethingabc"; private static final String LCDUID = "somethingabc"; private static final String ROTIUID = "somethingabc"; private static IPConnection ipc; private static BrickMaster master = new BrickMaster(MASTERBRICKUID); private static BrickletLCD20x4 lcd = new BrickletLCD20x4(LCDUID); private static BrickletRotaryPoti poti = new BrickletRotaryPoti(ROTIUID); public static void main(String[] args) { try { ipc = new IPConnection(HOST, PORT); ipc.addDevice(master); ipc.addDevice(lcd); ipc.addDevice(poti); poti.setPositionCallbackPeriod(50); poti.addListener(new BrickletRotaryPoti.PositionListener() { @Override public void position(short position) { lcd.clearDisplay(); Calendar cal = Calendar.getInstance(); lcd.writeLine((short) 0, (short) 0, cal.getTime().toString()); lcd.writeLine((short) 1, (short) 0, "Rotation: " + position); } }); } catch (Exception e) { } } } The result is that the display text in the LCD bricklet changes while I turn the rotation bricklet: Now imagine that you have some JavaFX charts and, while you turn the rotation bricklet (i.e., the dial thing that I'm turning above), the values of the charts change. That would be pretty cool because you'd be able to animate the JavaFX charts by rotating an object externally, i.e., without even touching the keyboard. That would be pretty cool to see and shouldn't be hard to implement.

  • Weird unexpected image compression on a web server running Apache on Ubuntu?

    - by Billy Bob Thornton
    I have a weird problem on my production web server running Apache on Ubuntu: it compresses my images thereby dramatically lowering their quality! Actually I have two virtual hosts running, each located in a different folder. Wether I display .gif images by navigating on the two sites, or acceding them directly by their url, their size and quality are invariably degraded. I tried with three different browsers: same problem. Using them on other sites on the Web: no problem. Of course I disabled mod_deflate on the server (which should not compress images anyway), but the phenomenon remains. On my local développement server, running the same configuration, everything is Ok. Now I'm completely lost! For the record, my configuration: Ubuntu 10.04, Apache 2, Php 5.

  • X-ming, Ubuntu apps - getting the Ubuntu style/theme to load

    - by user5402
    I am running X-ming on Windows 7 and using putty to ssh into an Ubuntu system. On the Ubuntu system I use the command: $ gnome-terminal & to display a terminal back on the Windows box. When I do this I don't get the standard Ubuntu style, i.e. dark purple background, Mono font, solid cursor (which I've configured in the Gnome Control Center.) Instead I get a very plain style - white background, blinking cursor, very small font. However, if I run gnome-control-center and then click on, say, the Keyboard icon, the terminal window will be reconfigured with the Ubuntu style with my customizations (e.g. block cursor vs. blinking cursor.) Just starting one of the control applets seems to trigger this style change. My question is: How can I trigger this style change more directly - without having to launch the Gnome Control center and launching one of the configuration applets?

  • Config import on network-manager-openvpn

    - by Toki Tahmid
    I'm trying to use a free service using the OpenVPN protocol using OpenVPN's GUI module in the network manager. The config worked perfectly well as .ovpn on Windows. The behavior in Windows is such that I ran OpenVPN GUI and chose to connect to this particular VPN. It would then show the activity in the attempt to connect and opens a dialog box for username/password authentication. I've successfully imported all the configurations by changing the file type to .conf and using the import feature in network manager. However, attempting to connect would simply display the network manager's attempting to connect animation, but ultimately end with a notification of connection timing out. No prompt asking for authentication would appear at all, nor can I find any feature to prefix the authentication details. client dev tun proto tcp remote miami.proxpn.com 443 resolv-retry infinite nobind persist-key persist-tun ca ca.crt cert client.crt key client.key cipher BF-CBC keysize 512 comp-lzo verb 4 mute 5 tun-mtu 1500 mssfix 1450 auth-user-pass reneg-sec 0 # If you are connecting through an # HTTP proxy to reach the actual OpenVPN # server, put the proxy server/IP and # port number here. See the man page # if your proxy server requires # authentication. ;http-proxy-retry # retry on connection failures ;http-proxy [proxy server] [proxy port #] Needless to say, but I've downloaded all the required packages for setting up OpenVPN connections. By the way, as you can see above, .key and .crt files location are specified to be in the same directory as the config file. After importing the config file, if were to remove them, would it cause any problem? Note, I haven't removed them, so the problem I'm facing is not due to the absence of these files.

  • Best way to let users choose country/language when submiting an URL to a directory

    - by Claudiu
    Hi all, I want to offer the user the possibility to add the country/language for websites they would submit to a fairly simple website directory. I have a folder with flags from http://www.famfamfam.com/lab/icons/flags/ . The flag images are named according to the ISO 3166-1 alpha-2 country codes, meaning that I could make a PHP script that would be able to retrieve images and the name of the country retrieved from the image name (not the full name, but it wouldn't be necessary). Just to make things clearer, I couldn't find a proper combo-box jQuery plugin for my needs (that would act exactly like the native but with an icon before the text) and don't really have the time to develop one on my own. Considering the number of images, I also wouldn't just display them all with a radio box near them. Also, having a classic drop-down list would be a nightmare for me as I would have to assign the short country name manually to each entry, or do it once for every country. Offering the user a dropdown list with the short country names but no flag near them would also be unfriendly and confusing. The idea is that every website featured in the directory would have the country flag icon near it. I have the images named properly but I don't know how to let the user choose the right image for their website. Any idees? Thank you all in advance! EDIT Temporary solution is this file: http://www.andrewpatton.com/countrylist.csv It contains a list of countries including various other info, like the short country name, the same name that's used for the flag images. I can take that information and have a classic like this: <select name="countries"> <option value="ro">Romania</option> <option value="ie">Ireland</option> <!-- and so on --> </select> Still, If anybody has a better idea...

  • Unity isn't starting on 13.10 (with Cinnamon 2.0 installed)

    - by Sam Pearman
    Since upgrading to 13.10, I can't log in to unity desktop. Light dm works correctly, but attempting to log in tries to start the session then drops back to light. I've already dropped to terminal (ctrl+alt+f2) and done this: sudo apt-get update sudo apt-get install --reinstall ubuntu-desktop sudo apt-get install unity Logging in as a guest session also fails. Logging in to other window managers works with varying degrees of success. Note: I have Cinnamon 2.0 installed from PPA. I'm using a 2 monitor setup. Also of note is that the session prior to my upgrade to 13.10 the background of unity failed to display at all, instead showing what was there in the screen buffer from the previous frame. The entire OS worked correctly otherwise though, so I just ignored it for the session. No other upgrades or even updates were done prior to this occurring. My upgrade path to 13.10 was basically this: Install 13.04 alongside Windows 7, use ubuntu as a glorified web browser for a while, get updates (in preparation for 13.10), install 13.10. I also used Unity Tweak Tool to change some aspects of unity, particularly auto-hide. Any help or ideas would be appreciated, as I'm typing this on my phone :(

  • I need advice on laptop purchase for university [closed]

    - by Systemic33
    I'm currently in University studying Computer Science/IT/Information Technology. And this first year i've managed to do with the laptop I had; an ASUS Eee PC 1000H with a 10.1" screen. But this is getting way too underpowered and small for programming more than just quick programming introduction excercises. So I'm looking to buy a more suitable laptop. It's not supposed to be a desktop replacement though, since I've got a pretty good desktop already with a 24" monitor. So the kinda laptop I want to buy is one suited for university. If this bears any significance, I'm working in Java atm, but I will likely work with lots of other things incl. web development. I'm looking to spend about $1700 plus/minus. And it should be powerful/big enough for working on programming projects as well as the usual university stuff like MATLAB, Maple, etc out "in the field", and sometimes for maybe a week when visiting my parents. What I'm looking at right now is the ASUS Zenbook UX31A with the 1920 x 1080 resolution on 13.3" IPS display. But I'm kinda nervous that this will be too petite for programming. In essence i'm looking for a powerfull computer, that has good enough battery, and looks good. I would love suggestions or any type of feedback, either with maybe a better choice, or input on how its like programming on 13" laptops. Very much thanks in advance for anyone who even went through all that! PS. I don't want a mac, or my inner karma would commit Seppuku xD But experiences from working on the 13" Macbook Air would kinda be equivalent to the Zenbook i'm considering, so I would love to hear that. tl;dr The quick brown fox jumps over the lazy dog ;)
