  • Blank Screen after inactive time

    - by Hari K T
    I am using Ubuntu 11.04 , on a DELL Vostro 1510. If I am inactive for a certain time, the screen usually gets locked and the login prompt will be there. Yes sometimes I am able to see the login screen and logging in as normal. But sometimes after its locked and when the mouse or keyboard is moved also nothing happens. This is happening for the second time. And its not happening always . I can switch from one terminal to other from the locked screen with Alt + + Ctrl F1 etc . But when I switch to the graphical one with Alt + Ctrl + F7 ( from the locked time ) I can see only a blank screen. I tried once login in ( Alt + Ctrl + F1 ) and trying to startx, but it said something was locked and want to delete the lock and try. So I removed don't remember what exactly it was . But it too was not a success , I was forced to press the powerbutton. Is this a bug ? I saw some but all are happening for switching users. Never experienced after logging out, but this happens only when its locked automatically actually. Update : I strongly feel this is a Bug. As I upgraded to 11.10 , I didn't noticed the same issues. But at some point if any one has an answer, you can post it. I can approve.

  • Potential issues with multiple home pages

    - by Maxim Zaslavsky
    I have a site where I want to have two different home pages: a general description page for anonymous users, and a dashboard page for logged-in users. I am debating between two implementations: Both pages live at / The page for anonymous users is located at / and the dashboard is at /dashboard, with automatic redirection between them based on whether a given user is logged in (e.g., if you're logged in and navigate to /, you are redirected to /dashboard. Is it cleaner to have both pages use the same URL or separate URLs? Also, I imagine that choices for that question will affect the following: Caching: the anonymous page would be completely cached, while the logged-in page would not be cached at all (except for static resources). This could lead to issues with server caching, request speed, and UX (such as if one version of the page is cached in a user's browser when the other version should be displayed, instead). SEO: how would search engines react to such canonical URLs? Load time (due to redirects or to the server having to always reevaluate which page to display)

  • Ubuntu 13.10 AMD/ATI proprietary driver slow boot time, lengthy login/logout delays

    - by NahsiN
    Ubuntu 13.10 is causing me major headaches with my AMD/ATI HD 5770 GPU. Below is a list of problems I am currently encountering. 1) The boot time is extended by at least 25s after installing catalyst 13.4. Using open source radeon drivers, my boot time till the login screen is ~10s. With catalyst 13.4 installed, the boot time increases to ~35s. This was not the case in Ubuntu 13.04, 12.10 or 12.04. I have done the driver installation manually (instructions from wiki.cchtml.com) and using software center and there is no difference. I have not tried the catalyst 13.8 beta driver. 2) After manual installation of catalyst 13.4, I get stuck at a black screen after logging in. I have to purge fglrx to resolve the problem. I tried sudo amdconfig --initial -f but it didn't help. 3) The delay between logging in and unity being displayed is ~10-15s for BOTH open source and proprietary drivers. During the delay, it's just a black screen. Whenever I logout, there is again a ~10-15s delay with the login screen appearing stuck before lightdm allows me to enter my password again. This is ridiculous! Yes, I could stick with open source radeon drivers but I would like to install Steam and play my Valve collection on the machine. Is anybody else encountering similar issues?

  • Is it normal for programmer to work on multiple projects simultaneously.

    - by gasan
    On a current job I have 2 projects to work on. First is very huge system and the second one is smaller but it also big (first project is being developed for 12 years, second for 4 years). At first I was working only on first project and was trying to get used to it. Then I was moved to second project and tried there, so my knowledge about first project became shady. Now I have to work on both projects at the same time. It's very hard for me because despite they both use java, they use different frameworks and the amount of code and business-logic to understand is very big so I really can't hold both that projects in my head. Is it normal and I should get used to it, although my expertise became very squashy, what won't happen if I would work only on a single project? Or should I raise a concern or maybe change employer?

  • How to create a reasonably sized urban area manually but efficiently

    - by Overv
    I have a game concept that only really works in an urban area that is of reasonable scale and diversity. In terms of what it should look like, think GTA, in terms of the size think more like a small neighbourhood with residents and a few local shops, perhaps a supermarket. I'm mostly experienced in programming and not at all with modelling, texturing or drawing, but I've found that SketchUp allows me to design interesting looking buildings that I model after real world buildings in my own neighbourhood. Designing these buildings and other objects can take from a few tens of minutes to a few hours. My question is: what is the best approach for a one man army like me who does manage to model buildings to create an interesting city environment in a reasonable amount of time? My game will not be based on procedural generation, the environment will actually be modelled like GTA cities.

  • Code Analysis In Python

    - by Jerub
    What tools are good to use for code analysis in python? I have a large source repository split across multiple projects, and I would like to be able to run tools across the directories to see details like Cyclomatic Complexity, and perhaps be able to spot errors using static analysis. Ideally, I would like to be able to produce a report about the health of the source code, so we can spot problem areas that need to be addressed.

  • How to schedule time-of-day upgrades

    - by Richard
    Hello, I'm responsible for about 30 Ubuntu computers at a private K-8 school. We have only a 3Mbps internet connection serving the entire campus, and I would like to ensure that updates are done in the middle of the night - so that daytime tasks are not slowed down. I'm using Ubuntu 10.04, and have set all computers to download and install security updates via the update manager. I have also installed cron-apt, and modified the config file to stagger the start times of the upgrades from about 10pm to 4am local time. HOWEVER - this morning I arrived at the school at 7:30am and all the computers were busy downloading a large security based update. Needless to say, all internet activity was slowed to a crawl (for the next 2 hours), and the computer users were very very upset. This was the event I'm trying so hard to prevent. It seems that my scheme to ensure middle of the night downloads failed, and I'm not sure why. I've also tried some schemes using unattended-upgrades & crontab, but there always seemed to be something scheduling upgrades to occur in addition to the ones I try to force at middle of the night. Is there a sure fire way to absolutely positively guarantee that updates will occur only at one specific time? It would be nice if the update manager just had a drop down menu to specify a designated time. Thanks in advance for any help you can give me.

  • What is the ideal laptop for creative coding applications?

    - by Jason
    Hi, I am a creative coder using C++(cinder and OpenFrameworks) I am looking to upgrade from my MacBook, which slowed down to about 3fps this morning. My project involves particles systems and fluids reacting to audio analysis data and computer vision data in real-time. SD or HD? no biggie. I have asked many people what computer I need. Ideally, I want a MacBook Pro. But is that enough power? I've been told that I need a desktop for what I am doing though I'd rather stay portable I've been told that I should go PC linux to get the most power but I'd rather stay mac I've been told that RAM is more of bottleneck than processor speed I've been told that the Graphics Card is more important than CPU and that code optimizations such as using trees over lists, proper threading, sending tasks to the GPU make a bigger difference than the hardware!!! what's true?! what do I need? Any suggestions are greatly appreciated

  • A fix for the design time error in MVVM Light V4.1

    - by Laurent Bugnion
    For those of you who installed V4.1 of MVVM Light and created a project for Windows Phone 8, you will have noticed an error showing up in the design surface (either in Visual Studio designer, or in Expression Blend). The error says: “Could not load type ‘System.ComponentModel.INotifyPropertyChanging’ from assembly ‘mscorlib.extensions’” with additional information about version numbers. The error is caused by an incompatibility between versions of System.Windows.Interactivity. Because this assembly is strongly named, any version incompatibility is causing the kind of error shown here (for an interesting discussion on the strong naming issue, see this thread on Codeplex). I managed to resolve the issue for Windows Phone 8 and will publish a cleaned up installer next week. In the mean time, in order to allow you to continue development, please follow the steps: Download the new DLLs zip package (MVVMLight_V4_1_25_WP8). Right click on the Zip file and select Properties from the context menu. Press the “Unblock” button (if available) and then OK. Right click again on the zip package and select “Extract all…”. Select a known location for the new DLLs. Open the MVVM Light project with the design time error in Visual Studio 2012. Open the References folder in the Solution Explorer. Select the following DLLs: GalaSoft.MvvmLight.dll, GalaSoft.MvvmLight.Extras.dll, Microsoft.Practices.ServiceLocation.dll and System.Windows.Interactivity.dll. Press “delete” and confirm to remove the DLLs from your project. Right click on References and select Add Reference from the context menu. Browse to the folder with the new DLLs. Select the four new DLLs and press OK. Rebuild your application, and open it again in Blend or in the Visual Studio designer. The error should be gone now. In the next few days, as time allows, I will publish a new MSI containing a fixed version of the DLLs as well as a few other improvements. This quick fix should however allow you to continue working on your Windows Phone 8 projects in design mode too.   Laurent Bugnion (GalaSoft) Subscribe | Twitter | Facebook | Flickr | LinkedIn

  • Longest Common Subsequence

    - by tsudot
    Consider 2 sequences X[1..m] and Y[1..n]. The memoization algorithm would compute the LCS in time O(m*n). Is there any better algorithm to find out LCS wrt time? I guess memoization done diagonally can give us O(min(m,n)) time complexity.

  • Raspberry Pi, Time Capsule Progress

    - by Richard Jones
    So by way of an update. I thought all was good with my Raspberry Pi, Debian and Netatalk Apple Time Capsule Clone. However something very strange going on. Although I could backup my Mac's + PC's fine to Raspberry Pi with external USB HD; strangely with RPI running, I couldn't use AirPlay. I found myself unable to play anything from Mac to Apple TV. So after lots of trying to make this work, I about turned and finally went out and got myself a 2TB Apple Time Capsule. More cash than I would want to spend on anything like this, but Apple you got me. I would like to offer a top tip, which maybe goes a small way to justifying silly expenditure... You can easily add a USB HD to any Time Capsule. I've just added a 3 TB external USB HD, giving me a 5 TB of total backup grunt. 3 TB External USB HD, was peanuts by comparison to Apple kit. So all working, its all solid as you'd expect.Apple 2, maybe me .5. But strong, solid backups now happening, without hassle (but a bit of a credit card bill to follow)

  • Question regarding Readability vs Processing Time

    - by Jordy
    I am creating a flowchart for a program with multiple sequential steps. Every step should be performed if the previous step is succesful. I use a c-based programming language so the lay-out would be something like this: METHOD 1: if(step_one_succeeded()) { if(step_two_succeeded()) { if(step_three_succeeded()) { //etc. etc. } } } If my program would have 15+ steps, the resulting code would be terribly unfriendly to read. So I changed my design and implemented a global errorcode that I keep passing by reference, make everything more readable. The resulting code would be something like this: METHOD 2: int _no_error = 0; step_one(_no_error); if(_no_error == 0) step_two(_no_error); if(_no_error == 0) step_three(_no_error); if(_no_error == 0) step_two(_no_error); The cyclomatic complexibility stays the same. Now let's say there are N number of steps. And let's assume that checking a condition is 1 clock long and performing a step doesn't take up time. The processing speed of Method1 can be anywhere between 1 and N. The processing speed of Method2 however is always equal to N-1. So Method1 will be faster most of the time. Which brings me to my question, is it bad practice to sacrifice time in order to make the code more readable? And why (not)?

  • Is there a name for this use of the State design pattern?

    - by Chris C
    I'm looking to see if there is a particular name for this style of programming a certain kind of behavior into a program. Said program runs in real time, in an update loop, and the program uses the State design pattern to do some work, but it's the specific way it does the work that I want to know about. Here's how it's used. - Object Foo constructed, with concrete StateA object in it - First loop runs --- Foo.Run function calls StateA.Bar --- in StateA.Bar replace Foo's state to StateB - Second loop runs --- Foo.Run calls StateB.Bar - Third loop runs --- Foo.Run calls StateB.Bar - Fourth loop --- etc. So in short, Foo doesn't have an explicit Initialize function. It will just have Run, but Run will do something unique in the first frame to initialize something for Foo and then replace it with a different action that will repeat in all the frames following it- thus not needing to check if Foo's already initialized. It's just a "press start and go" action. What would you call implementing this type of behavior?

  • Time Zone on WebLogic Server

    - by adejuanc
    In order to configure the time zone with WebLogic Server, use the following JVM startup command: -Duser.timezone=<timezone> For example, in the java arguments in the admin console at Environments -> Servers -> Servername -> - Server Start tab, configure the startup settings that Node Manager will use to start the particular server. For example: -Duser.timezone='America/Arizona' There are many different time zones, each with its own code. For a complete list please refer to : http://en.wikipedia.org/wiki/List_of_zoneinfo_time_zones For testing, you can run the following code on WLS with a JSP, servlet, or deploying the class: import java.util.Calendar; import java.util.TimeZone; public class TestTimeZone {  public static void main(String[] args) {    Calendar calendar = Calendar.getInstance();    TimeZone timeZone = calendar.getTimeZone();    System.out.println(" your Current TimeZone is : " + timeZone.getDisplayName());    System.out.println(" Time Zone id : "+ timeZone.getID());  } }

  • Let's do the Time Warp again!

    - by Mike Dietrich
    Once you start reading about Daylight Saving Time changes in MyOracleSupport you'll find still a lot of notes explaining this and that and back and forth. But sometimes there seems to be a bit too much information - and lacking clear instructions. Once a customer called that the "Time Zone Spaghetti" after reading MOS notes about DST for several hours ending up with the note where he has begun to read before still not clear what to do now I'm using usually the scripts from MOS Note:977512.1 as you'll just have to exchange the DST version you are upgrading to and it has everything you need to check and adjust the time zone data in the database - for instance after applying the DST V18 patch to your database's homes. As a reminder to myself when traveling I have stored a copy of the script part of that note here - and please note that this is not an official Oracle version. Always read and check the original MOS Note:977512.1 as it may have gotten changed in between and may contain changes or corrections and as it has a lot of more explainationary information than I could cover here. And credit to Gunter Vermeir from Oracle Support, who is the owner of that MOS Note and has compiled all that useful stuff together. DST_prepare.sql DST_adjust.sql

  • How to balance programming projects between feasibility and usefulness

    - by tyjkenn
    I've become fairly competent as a programmer, but I would not say I am a master. I work independently, most as a hobby, although I have done some freelance PHP work. I tend to find myself dabbling in a lot of things: Java Android SDK, Arduino, game scripting, Lua, etc. I've reached the point where I want to start a real software project, but cannot think of a small enough project that allows me enough practice, while still being able to publish a decent piece of software in a reasonable amount of time, and build up a portfolio. More specifically, I was looking at Ubuntu development, in Python, using the Quickly toolset, which includes the PyGTK libraries. So the question is, what is the best way to come up with a small project that is still useful, as a starting point to a software development career?

  • Worst Case number of rotations for BST to AVL algorithm?

    - by spacker_lechuck
    I have a basic algorithm below and I know that the worst case input BST is one that has degenerated to a linked list from inserts to only one side. How would I compute the worst case complexity in terms of number of rotations for this BST to AVL conversion algorithm? IF tree is right heavy { IF tree's right subtree is left heavy { Perform Double Left rotation } ELSE { Perform Single Left rotation } } ELSE IF tree is left heavy { IF tree's left subtree is right heavy { Perform Double Right rotation } ELSE { Perform Single Right rotation } }

  • Very slow startup after update to 12.04

    - by M Legoh
    My hardware: Dell Latitude D600 laptop Processor: Intel Pentium (r) 1.8 GHz Memory 1.2 GiB Graphics R200 (RV250 4C66) x86/MMX/SSE2 TCL DRI2 Disk: 37.7 gb I did an update from 11.?? using the automatic system update that pops up when you switch/log on. Ever since then when I switch on the machine it takes approximately one hour to get to the login screen. Sometimes the actual login will take time too, but sometimes within a couple of minutes I am logged in. Once I am logged in I find I can work normally, the response is not swift, but is neither too slow that I cannot work. I was wondering if there was anything I could do to speed things up. I deliberately did not do a clean install from disk, because I did not want to loose settings on the machine.

  • Where does Rails get it's datetime for creating records?

    - by gwapEs9
    I have a rails app with a data model called 'jobs' and i'm faced with a critical design choice crossroads. I don't know enough about Rails and it's inner workings to be able to say for sure what I should do despite a complete read of the rails and ruby docs. I want to be able to accurately display the age of a job record in days. So when a customer logs in, they can see that the job they submitted is 'x' days old. Where does a rails app on Heroku get it's time stamps? From Heroku? or the customers system clock? If a customer has a out of date system clock and submits a job, it could really mess up the sorting of their job list, not to mention me the overseer of job records. Any advice out there? EDIT: Just to be clear, i'm not asking how to list jobs by their date, but to which clock does a rails app on Heroku base it's records.

  • Should I pay my developers for bugs fixes for a project or work that's still in progress?

    - by Wanda Pebbs
    We are working with a group of developers on a project. The project is still in progress (not completed) and these developers charge us for time spent on fixing bugs on codes that were not written valid in the first place. I understand that we should pay for changes/new requests if any, but not bugs fixes for a work in progress. We also understand that once the assignment is being deployed to the live site, we may be liable for bugs fixes that may arise after a support period is being exhausted. The question now is, is it appropriate for such charges to be levied upon us while the project is still in progress?

  • Automatically delete files after they expire

    - by Auxiliary
    I've got this idea for some time and I was wondering if anyone has seen such a feature/app in any operating system and if you haven't, what do you think about it. Where do you think I should begin? The idea is simple. I think we all have those files that are made and probably used for a few days and then are left on our disk and we never delete them or even check to see if we need them again. It'd be cool if you could right click on a file and click on "Expire in.. 3 days" for example. And the file gets deleted after 3 days. I have a great need for this and maybe some people will find it useful. I was thinking of writing a script and use the Nautilus Action project in GNOME for a start.

  • How to deal with a ten days debugging session? [on hold]

    - by smonff
    Ten days ago, I fixed a bug on a large application and the hot fix has created a disappearing of some data from the user point of view. Data are not deleted, but have been set to hidden status. It could be possible to get the data back, but the thing seems to be hard: I've already spent 10 days to understand and reproduce the problem (mostly with complex SQL queries but sometimes it is necessary to update the database to test the application logic). Is 10 days a normal amount of time for these kind of problems? Should we keep on and retrieve the data or should we tell these users sorry for the loss, but your data have disappeared? Any advice on when to stop searching how to solve the issue?

  • Script to UPDATE STATISTICS with time window

    - by Bill Graziano
    I recently spent some time troubleshooting odd query plans and came to the conclusion that we needed better statistics.  We’ve been running sp_updatestats but apparently it wasn’t sampling enough of the table to get us what we needed.  I have a pretty limited window at night where I can hammer the disks while this runs.  The script below just calls UPDATE STATITICS on all tables that “need” updating.  It defines need as any table whose statistics are older than the number of days you specify (30 by default).  It also has a throttle so it breaks out of the loop after a set amount of time (60 minutes).  That means it won’t start processing a new table after this time but it might take longer than this to finish what it’s doing.  It always processes the oldest statistics first so it will eventually get to all of them.  It defaults to sample 25% of the table.  I’m not sure that’s a good default but it works for now.  I’ve tested this in SQL Server 2005 and SQL Server 2008.  I liked the way Michelle parameterized her re-index script and I took the same approach.

  • Changing the system time zone succeeds once and then no longer changes

    - by Adam Driscoll
    I'm using the WinAPI to set the time zone on a Windows XP SP3 box. I'm reading the time zone information from the HKLM\Software\Microsoft\WindowsNT\Time Zones\<time zone name> key and then setting the time zone to the specified time zone. I enumerate the keys under the Time Zones key, grab the TZI value and stuff it into a TIME_ZONE_INFORMATION struct to be passed to SetTimeZoneInformation. All seems to work on the first pass. The time zone changes, no error is returned. The second time I perform this operation (same user, new session, on login before userinit) the call succeeds but the system does not reflect the time zone change. Neither the clock nor time stamps on files are updated to the new time zone. When I navigate to: HKLM\System\CurrentControlSet\Control\TimeZoneInformation my new time zone information is present. A couple strange things are happening when I'm setting my time zone: Also when I parse the TZI binary value from the registry to store in my TIME_ZONE_INFORMATION struct I'm noticing the struct has the DaylightDate.wDay and StandardDate.wDay field always set to 0 I tried to call GetTimeZoneInformation right after I call SetTimeZoneInformation but the call fails with a 1300 error (Not all privileges or groups referenced are assigned to the caller. ) I'm also making sure to send a WM_BROADCAST message so Explorer knows whats going on. Think it's the parsing of the byte array to the TIME_ZONE_INFORMATION struct? Or am I missing some thing else important? EDIT: Found a document stating why this is happening: here. Privilege was introduced in Vista...thanks MSDN docs... Per the Microsoft documentation I'm enabling the SE_TIME_ZONE_NAME privilege for the current processes token. But when I attempt to call LookupPriviledgeValue for SE_TIME_ZONE_NAME I get a 1313 error (A specified privilege does not exist. ).
