  • Ubuntu odd mouse and keyboard behavior when window gains inner focus

    - by Scott
    This morning on my Ubuntu 10.10 system when I open a window - for example, system-preferences-about me, if I click in to a field such as "work email", I can no longer close the window with the mouse! Clicking the X on the window will not work. Also, I loose the ability to click on anything else - clicking on the desktop, icons, menus, workspaces, etc. do not work. Even the effect when you hover over a folder on the desktop and that folder highlights - that stops until the window is closed. If I open this same screen but do not click in to a field, everything is fine - I can close the window with the X and everything else works fine. Same thing happens with several other windows I tried. Even calculator - I can open it, everything is fine until I click on a button in the calculator - then no ability to click on anything else. Have to Alt-F4 to close the window. The system is only about a week old from a fresh install (64 bit ubuntu - quad core amd machine). I uninstalled wine, turned off remote desktop/disabled in startup, also in startup disabled visual assistance, bluetooth, dropbox, klipper. Reboot, no difference. The only other thing non-standard I see in startup is nvidia. Using a logitec usb mouse, saitek usb keyboard. Was working fine yesterday. I can not think of anything I did / installed yesterday. I switched themse, then went to update manager and saw two x server / x org related updates and installed them, reboot and NOW IT IS FINE! However, then I re-enabled dropbox, klipper and remote desktop rebooted and the problem is back. Again I disabled and rebooted. Problem is still there!! So somehow I fixed it at least for a few minutes, but now it is back and I am out of ideas.

  • Odd SVN Checkout failures occur frequenctly on VMWare virtual machines

    - by snowballhg
    We've recently been experiencing seemingly random SVN checkout failures on our Hudson build system. Google search has failed me; I'm hoping the super user community can help me out :-) We are occasionally receiving the following SVN error when our Hudson build jobs checkout source via the Hudson Subversion plug-in (which uses svn kit): ERROR: Failed to check out http://server/svnroot/trunk org.tmatesoft.svn.core.SVNException: svn: Processing REPORT request response failed: XML document structures must start and end within the same entity. (/svnroot/!svn/vcc/default) svn: REPORT request failed on '/svnroot/!svn/vcc/default' This issue seems to only occur when checking out from our Virtual Machines (Windows XP, Fedora 9, Fedora 12) using Hudson's SVN Plug-in. Systems that use the traditional SVN client seem to work. SVN Server version: 1.6.6 Hudson version: 1.377 Hudson SVN Plugin Version: 1.17 Has anyone dealt with this issue, or have any suggestions? Thanks

  • Odd FTP ASCII/BINARY transfer behavior after migrating to a new server

    - by Incognita Mundi
    I recently got a dedicated server and after migration to the new machine I started noticing problems with file transfers. My FTP client, despite being set to auto, keeps uploading php files in binary mode and the content of those files is messed up. Since I mostly upload files of different kinds it would be annoying to change from binary to ASCII every single time, beside, I never had such problems. What could be the cause of this behavior? My dedicated server runs CENTOS 6.4 and the ftp server is Pure-FTPd. I tried different FTP clients and they all have the same problem so I assume is soem misconfiguration on the server side. Thanks

  • Odd Apple AirPort Express behaviour

    - by MatthewD
    I've been using a rather old AirPort Express for home Wi-Fi for a number of years. (It's old enough that it only supports WPA, not WPA2 -- perhaps this is an indication that I should upgrade!) In the last week I've been experiencing very slow internet over the Wi-Fi. Suspecting that someone outside my home was leeching from me (despite a reasonable password and MAC address filtering turned on) I decided to change some settings: I changed the SSID, turned off broadcast of the SSID and changed the password. After these changes, I managed to connect using the new password on my iPad. But on the other devices I tried (iPhone, PS3) I was not able to connect. In fact, I only succeeded in connecting when I entered my OLD password! Is this a known issue with ancient AirPort Express units? Is my unit cracked and unrecoverable?

  • Wireless slow, but very odd

    - by Logman
    I have a HP Pavilion dv6 laptop, internet through the wireless timeouts. Even though it connects fine to the AP/router. The computer had a virus (searchnu?) and I backed up the usual and restored the laptop to factory image. Problem is after the restore the internet through the wireless the same still... and connected via wired and everything worked fine. I was able to update the whole system. Internet worked perfect, speed great. But the wireless still was pitiful. Ping tests with wireless are interesting: Google= 18ms Gmail= 18ms Yahoo= 1023ms 8.8.8.8=30ms Microsoft= Request Timed Out Bing= Request Timed Out msn= Request Timed Out even though I get 18ms with google, the pages take a long time to load. Is this a root kit? is it the wireless card in the laptop?

  • Odd Language In a BIOS Message

    - by Josh
    So I started up my laptop today and was greeted with the following message (not a direct quote): The type of the AC adapter cannot be determined. This may interfere with your computer's performance. Try unplugging the AC adapter and then plugging it back in, thanks. The problem was that I hadn't fully secured the plug into the back of the computer. However, I was a little taken aback when a message from BIOS said, "thanks." Is this normal? Any chance the message was illegitimate (virus)?

  • Odd behavior of permissions and icons

    - by Urban
    After some virus had infected my Windows 7, I did a complete format and re-installed the OS. I was just installing applications and copying back some data when I noticed some shortcuts changing their icons to something I couldnt recognize (Yellow icons in the image below). Also, a few exe files which previously did not ask for User permission, are now asking for it. Wondering if this is an icon cache problem, I cleared the cache by deleting the IconCache.db in AppData/Local but the problem still persists. Although I did a full system scan with MS Security Essentials, I'm not sure if this is another virus or some other problem. I would appreciate any suggestions you might have. Edit: Now even Firefox needs permissions to launch. It's icon hasnt changed, but it's got the 'shield' overlay on it like the other yellow icons.

  • catching a deadlock in a simple odd-even sending

    - by user562264
    I'm trying to solve a simple problem with MPI, my implementation is MPICH2 and my code is in fortran. I have used the blocking send and receive, the idea is so simple but when I run it it crashes!!! I have absolutely no idea what is wrong? can anyone make quote on this issue please? there is a piece of the code: integer,parameter::IM=100,JM=100 REAL,ALLOCATABLE ::T(:,:),TF(:,:) CALL MPI_COMM_RANK(MPI_COMM_WORLD,RNK,IERR) CALL MPI_COMM_SIZE(MPI_COMM_WORLD,SIZ,IERR) prv = rnk-1 nxt = rnk+1 LIM = INT(IM/SIZ) IF (rnk==0) THEN ALLOCATE(TF(IM,JM)) prv = MPI_PROC_NULL ELSEIF(rnk==siz-1) THEN NXT = MPI_PROC_NULL LIM = LIM+MOD(IM,SIZ) END IF IF (MOD(RNK,2)==0) THEN CALL MPI_SEND(T(2,:),JM+2,MPI_REAL,PRV,10,MPI_COMM_WORLD,IERR) CALL MPI_RECV(T(1,:),JM+2,MPI_REAL,PRV,20,MPI_COMM_WORLD,STAT,IERR) ELSE CALL MPI_RECV(T(LIM+2,:),JM+2,MPI_REAL,NXT,10,MPI_COMM_WORLD,STAT,IERR) CALL MPI_SEND(T(LIM+1,:),JM+2,MPI_REAL,NXT,20,MPI_COMM_WORLD,IERR) END IF as I understood even processes are not receiving anything while the odd ones finish sending successfully, in some cases when I added some print to observe what is going on I saw that the variable NXT is changing during the sending procedure!!! for example all the odd process was sending message to process 0 not their next one!

  • Why does the use of interface-based programming appear to be limited to behaviour?

    - by Carnotaurus
    I have been doing a little thinking about inheritance vs. realization vs. composition. I am not about to post the whole detail here. So I was wondering, when are not talking about supporting unit testing: Why does interface-based programming seem to focus upon the grouping of common behaviour, e.g., IPettable (for an animal), IEditable (for a user control), ISubmitable (for a form), etc. Why does the use of interface-based programming appear to be limited to behaviour when we could pragmatically group not so much on behaviour but on commonsense physical similarities which could have nothing to do with behaviour? It is not that there is some limiting feature within OOP; so how come?

  • mod_proxy incorrect redirect behaviour

    - by Kevin Loney
    In chrome this configuration causes an infinite redirect loop and in every other browser I have tried a request for https://www.example.com/servlet/foo is resulting in a redirect to https://www.example.com/foo/ instead of https://www.example.com/servlet/foo/ however this only occurs when I do not include a trailing / at the end of the request url (i.e. http://www.flightboard.net/servlet/foo/ works just fine). <VirtualHost *:80> # ... RewriteEngine On RewriteCond %{HTTPS} off RewriteCond %{REQUEST_URI} ^/servlet(/.*)?$ RewriteRule ^(.*)$ http://%{HTTP_HOST}$1 [R=301,L] </VirtualHost> <VirtualHost *:443> # ... ProxyPass /servlet/ ajp://localhost:8009/ ProxyPassReverse /servlet/ ajp://localhost:8009/ </VirtualHost> The virtual host on port 443 has no rewrite rules that could possibly causing the problem, the tomcat contexts being referenced do not send any redirects, and if I change the ProxyPass and ProxyPassReverse directives to: ProxyPass / ajp://localhost:8009/ ProxyPassReverse / ajp://localhost:8009/ everything works fine (except for the fact everything from www.example.com is being passed to the proxy which is not the behaviour I want). I'm fairly certain this is a problem with the way I have my proxy settings configured because I did log all the rewrite output coming from apache and it was all correct.

  • Unexpected behaviour in a Lotus Notes programmable table

    - by Mark B
    I'm designing a workflow database in Lotus Notes 6.0.3 (soon upgrading to 8.5), and my OS is Windows XP. I have recently tried converting a tabbed table into a programmable one. This was so that I could control which tab was displayed to the user when it was opened, so that they were presented with the most appropriate one for that document's progress through the workflow. That part of it works! One of the tabs features a radio button that controls visibility of the next tab, and a pair of cascading dialogue boxes. One contains the static list "Person":"Team", and the other has a formula based on the first: view:=@If(PeerReview = "Team"; "GroupNames"; "GroupMembers"); @Unique(@DbColumn(""; ""; view; 1)) The dialogue boxes have the property "Refresh fields on keyword change" selected. The behaviour that I wasn't expecting is this. If the radio button is set to "Yes" and a value is selected in one of the dialogue boxes, the table opens the next tab. If the radio button is set to "No" and a value is selected in one of the dialogue boxes, the entire table is hidden. I can duplicate the latter by switching off the "Refresh fields on keyword change" property on the dialogue boxes and instead pressing F9 after selecting a value. I have no idea why the former occurs, though. The table is called "RFCInfo", and I have a field on the form called "$RFCInfo" which is editable, hidden from all users who aren't me and initially set by a Postopen script, which I can post if necessary - it's essentially a Select Case statement that looks at a particular item value and returns the name of the table row relating to that value. Can anyone offer any pointers?

  • Interesting LinqToSql behaviour

    - by Ben Robinson
    We have a database table that stores the location of some wave files plus related meta data. There is a foreign key (employeeid) on the table that links to an employee table. However not all wav files relate to an employee, for these records employeeid is null. We are using LinqToSQl to access the database, the query to pull out all non employee related wav file records is as follows: var results = from Wavs in db.WaveFiles where Wavs.employeeid == null; Except this returns no records, despite the fact that there are records where employeeid is null. On profiling sql server i discovered the reason no records are returned is because LinqToSQl is turning it into SQL that looks very much like: SELECT Field1, Field2 //etc FROM WaveFiles WHERE 1=0 Obviously this returns no rows. However if I go into the DBML designer and remove the association and save. All of a sudden the exact same LINQ query turns into SELECT Field1, Field2 //etc FROM WaveFiles WHERE EmployeeID IS NULL I.e. if there is an association then LinqToSql assumes that all records have a value for the foreign key (even though it is nullable and the property appears as a nullable int on the WaveFile entity) and as such deliverately constructs a where clause that will return no records. Does anyone know if there is a way to keep the association in LinqToSQL but stop this behaviour. A workaround i can think of quickly is to have a calculated field called IsSystemFile and set it to 1 if employeeid is null and 0 otherwise. However this seems like a bit of a hack to work around strange behaviour of LinqToSQl and i would rather do something in the DBML file or define something on the foreign key constraint that will prevent this behaviour.

  • Strange DataTable behaviour

    - by DocSnuggles
    There´s a strange behaviour in my code which I can´t explain... I have worked arround it but I´d like to know the reason of this behaviour. My Code: If dataset.Tables.Count > 0 Then Dim rows() As DataRow = dataset.Tables(0).Select("FileID = " + fileid.ToString) For Each row As DataRow In rows... the one and only table in dataset is: 18 1 1 testpara42 19 1 2 Para2 23 2 1 Para1 24 2 2 Para42 Where the colums are: ParamID - FileID - ParaPos - Paravalue. I want do filter it so that the only rows I get are the ones with the correct fileid... the result when the selection string is "FileID = 1" is an array with 2 rows... everything is fine... but the filter string "FileID = 2" will return 0 Rows... A filter like "FileID < 1" returns 2 Rows correctly. I really cant´t explain this od behaviour, maybe one of the community does. The Table does have more entries but the Filter string just works with the "FileID = 1" selection. Excuse my bad english. Please explain my mistake to me.

  • Ubuntu Lucid: Erratic screen behaviour after boot

    - by fgysin
    In short: about 50% of the time I have a screwed up monitor setup after reboot. About 50% it is totally correct. Now the longer version: I updated my machine from 9.04 to 10.04 (via 9.10). At first I run into some monitor problems (I have a 3-monitor setup) because of the known bug in the new xserver driver for xinerama. This messes up behaviour if the mouse goes either left or above the screen number 0, i.e. I had to make my left-most monitor screen 0. Everything worked out fine finally, I got my 3-monitor setup back with xinerama enabled to get one big desktop streched over 3 screens. Now the fun part: Every time I start up my machine only one of the 3 monitors gets a signal and is woken up: it only recognizes the left-most monitor (screen 0) and crams all the desktop stuff into this one screen. If I go into nvidia settings I only see one physical device although all 3 are connected and have power. When I look into the xorg.conf I can still see my old setup with 3 devices, 3 screens, xinerama active etc... But I was totally unable to get 3 montitors to work. (I tried unplugging monitors, reconfiguring whole nvidia setup, ...) But it gets even better: When I restart my machine (i.e. choose the restart option from the Ubuntu menu) it shuts down and tries to restart. The restart then gets stuck after showing the Ubuntu splash screen with the 'loading bar' (the moving dots thingy) and I am forced to kill the machine by cutting power. But after the power cut the machine boots up normally and suddenly I get my 3 monitor setup back up working. That is until the next time I shut down and start up, where it all starts over again and I only have one monitor... (see above) I really have a hard time seeing where the error is. It must be that the restart boot somehow differs from the 'normal' boot. But the fact that it gets stuck and I need to cut power which then basically triggers a 'normal' boot does not really support this theory... My setup (please tell me if you need further info): 3 monitors as 3 screens as one desktop (with xinerama) 2 nvidia cards where screen 0 and 1 are on card 0 and screen 2 is on card 1 Ubuntu 10.04 Lucid Lynx (updated from 9.10, 9.04, ....) I would appreciate every idea on the subject, at the moment I really don't have any clue what to do...

  • I need to unset the state of the jQuery .toggle(odd,even)

    - by Forkrul Assail
    Hi I have items in a table cell that gets toggled on and off. An external button accepts a click and submits the selected cell values via ajax. The problem is that I want to reset the toggle state for the selected cells. I can easily unset the highlighting, but then need a double click to trigger the correct toggle. Can the .toggle(odd, even) be reset or cycled via an external call? Thanks

  • Odd Drag and drag bug in nested attributes Rails

    - by Senthil
    I've got this weird bug when trying to use drag and drag for two models (one nested within another). I've a category model which has many apps. In my category index page, I tried use "content_tag_for" to sort categories and apps within each category. But for some odd reason only the first element has drag, drop enabled. I can drag and drop categories all I want, but I can't drag the app in the second category, just the first category. Copy and paste gets ridiculously hopeless with HAML, so here's a Pastie instead. I made a sample app on heroku for you to check out here. Drag and drag work for both category and app, so I'm guessing it has to do something with the ul or li. Any help is appreciated. Thanks.

  • [ASP.NET] Odd HttpRequest behaviour

    - by barguast
    I have a web service which runs with a HttpHandler class. In this class, I inspect the request stream for form / query string parameters. In some circumstances, it seemed as though these parameters weren't getting through. After a bit of digging around, I came across some behaviour I don't quite understand. See below: // The request contains 'a=1&b=2&c=3' // TEST ONLY: Read the entire request string contents; using (StreamReader sr = new StreamReader(context.Request.InputStream)) { contents = sr.ReadToEnd(); } // Here 'contents' is usually correct - containing 'a=1&b=2&c=3'. Sometimes it is empty. string a = context.Request["a"]; // Here, a = null, regardless of whether the 'contents' variable above is correct Can anyone explain to me why this might be happening? I'm using a .NET WebClient and UploadDataAsync to perform the request on the client if that makes any difference. If you need any more information, please let me know.

  • Strange behaviour of code inside TransactionScope?

    - by Krishna
    We are facing a very complex issue in our production application. We have a WCF method which creates a complex Entity in the database with all its relation. public void InsertEntity(Entity entity) { using(TransactionScope scope = new TransactionScope()) { EntityDao.Create(entity); } } EntityDao.Create(entity) method is very complex and has huge pieces of logic. During the entire process of creation it creates several child entities and also have several queries to database. During the entire WCF request of entity creation usually Connection is maintained in a ThreadStatic variable and reused by the DAOs. Although some of the queries in DAO described in step 2 uses a new connection and closes it after use. Overall we have seen that the above process behaviour is erratic. Some of the queries in the inner DAO does not even return actual data from the database? The same query when run to the actaul data store gives correct result. What can be possible reason of this behaviour?
