  • Eclipse on Ubuntu: Rectangles instead of Strings and some Java methods and classes

    - by Claus Hausberger
    after upgrading from Ubuntu 9.04. to 11.04 (new installation), I have weird problems with the Eclipse editor. With the Eclipse PyDev plugin, whenever I typ single quoted strings like 'bla', they appear as rectangles (both the quotes as well as the string). First I thought this was a problem with the PyDev plugin, but it also happens with Java and Scala Plugins. With Java, it happens, for example, when typing System.out.println("bla") and then "out" is shown as rectangles only. Weird is that for about half a second I see "System.out.println" and then the editor changes it to System.[][][].println (not really [] (here I used two brackets), it is shown as rectangles). This is very weird. I've never had this before with any Ubuntu, Java or Eclipse version. Currently, I use: Ubuntu 11.04. Eclipse 3.6 Java 1.6.0_25 The latest plugins for Python (2.1) and Scala (beta 5) where used. Eclipse and Ubuntu Terminal is set to UTF-8. The problem also happens when using KDE instead of Gnome. I doubt is has anything to do with Java as I use the same versions on older Ubuntu installations (10.04, 9.10, etc) at work. It does not happen with Netbeans. But I saw once error dialog message from the Update Manager where there were some rectangles in the error widget. Maybe this is the same problem Any ideas what could be wrong here and how to fix this? Eclipse is unusable but I need this for work and also for Scala and Python (the Eclipse plugins for those are very good now). Claus

  • Router not connecting to the internet

    - by Peter
    I had a weird problem this morning with my router - it's an Alice Gate VoIP 2 Plus WI-FI - not connecting to the internet after more or less 1 hour online (I'm always connected with the ethernet cable). The led status lights for Power, WI-FI, ADSL, Internet, Service should be on in order to be connected and navigate online. The problem was that the leds ADSL, Internet were off and I did not know why because it never happened before. I looked at the stats in the settings and the numbers for Bytes/Packages for both Sent/Received were there and increasing but I couldn't connect to the internet. I called tech support, they checked and told me to keep the router on for 48 hours because they were checking it. I've reset it twice before and after I called tech support and it still did not work so after about 2 hours of waiting I tried connecting using WI-FI and the leds 'magically' turned on, first the ADSL and Internet(Internet led always turns on last). At this point I'm curious what could of caused this and I'm doubting that the tech-support guys did something. What could of been the problem with the ethernet cable not connecting in the first place? It always works. What do the tech support guys normally do when they tell me to keep the router on so they can 'check it'? PS: I'm using ubuntu 32 bit

  • I/O Error on LG GSA-H12N DVD drive on Windows 7

    - by Ashwin
    I am facing an I/O Error when I try to burn DVD data discs on my LG GSA-H12N DVD drive on Windows 7. Note that I was able to do this same operation on the same hardware/software just a day earlier without any problems, but with Windows XP. The only change (AFAIK) has been the installation of Windows 7 to replace Windows XP on this PC. Here is the error I get when I try to burn a DVD data disc using CDBurnerXP 4.2.7.1801: Burning error occured An error occured while burning the disc. Most likely the disc is not usable. Usually these errors happen if the inserted media is not compatible to the drive or of poor quality. (devNTSPTI_IO_Error) Could not write to Disc (LBA: 52864 Length: 32). SCSI Pass-through Interface I/O Error. - 0xFF045D Note that there can be no problem with the discs since I have been using the same discs (from the same box) just before the Windows 7 installation with no problems. The only change has been Windows 7. I tried InfraRecorder v0.5 and ImgBurn v2.5 and got similar I/O errors: Note that Windows 7 lists the LG GSA-H21N drive as being compatible (see this link). I also checked the LG Drivers website and using the firware update from there updated the drive firmware from version UL01 to UL02. But, even this has not helped. The drive reads DVDs without any problem, but continues to produce coasters. Could someone help me figure out what is the problem? Thanks :)

  • Emptying Windows temp folder is a good idea?

    - by Siva Charan
    Am using DELL Inspiron with Windows 7. As far as I know emptying the windows temp folder would be good. But I faced a strange behaviour around 8 months back, when I clear my windows temp folder. The next day onwards, my laptop starting displaying daily one or other errors and one day OS got crashed. Till now I am not sure whether OS got crashed due to clearing the windows temp folder or something else is problem. Here Windows temp folder mean "C:\Windows\Temp" This is the behind the story. Today, this temp folder "C:\Windows\Temp" contains 102 GB Most of the space occupied by the files starts with etilqs_*.*. I came to know that these files are generated due to WD SmartWare. Now my problem is:- Actually I want clean up this folder, since it occupies lot of space. If I clean up "C:\Windows\Temp" folder, will my laptop face the same kind of problem which I faced earlier OR Any new problems will occur? Please suggest me a good solution.

  • Back-to-back ajax long poll without a recursive callback function.

    - by Teddy
    I'm trying to make long poll ajax calls, back to back. The problem with the current way I'm doing it is that I make each successive call from the callback function of the previous call. Is this a problem? Firebug doesn't show any of my ajax calls as completed, even thought the data is returned and the callback is executed. The recursive structure seems inefficient. Any ideas?

  • Control copy/paste doesn't work

    - by Guest
    I have a laptop HP PAVILION dv6-3126er with Windows 7 Home Edition installed and neither control copy nor control paste doesn't work (i've tried: ctrl+c, ctrl+v, shift+c, shift+v, ctrl + insert, shift + insert). I've tried to run a system check through cmd with sfc /scannow, it repaired something, i restarted but it didn't solve the problem. I've also tried many key combinations (like alt+ctrl+fn), but nothing works in any program. In Microsoft Word 2003 in the menu i have no key combination for copy/paste near them (in my previous comp they've been there - in brackets). Shift+Delete works by the way. I brought this laptop a few weeks ago, and i discovered this problem in the first days. I have no viruses because i have had no time to even connect him to internet. Anyways, i checked it for viruses - it is clean. I don't want to do system restore, because i see no reason to do it for a pretty clean system. I hope it is not a problem with the laptop itself. Maybe there is another reason? Maybe i need to do some more system checks? Any suggestions? Thanks in advance.

  • Need help with local network printing while using VPN on Ubuntu 10.10 desktop

I can guess it is an mdns problem, but searching google about mdns didn't turn up anything that seemed related to this (at my level of knowledge). Any suggestions?

  • Changing the itemsSource of a treeview makes it's children invisible, when they were already display

    - by Marnix Kraus
    I found some strange problem in WPF, using the itemsSource of a treeview. I hope I can make this specific problem clear for you. First; a story. There is a treeview. It has a list with treeviewitems as itemsSource. This list is called _roots. There is another list, called _leafs. For as in a treeview, the _roots contain the _leafs in some hierarchical way. For example: <TreeviewItem Header="Jungle"> <TreeviewItem> <SpecialTreeviewItem Header="Monkey"/> <SpecialTreeviewItem Header="Apple"/> </TreeviewItem> </TreeviewItem> Now I am trying to switch between these two lists as itemsSource. It seemed to work fine, but it doesn't: When the Jungle-item is un-expanded, and I change the itemsSource to _leafs, and change it back again to _roots, everything works fine and all items can be expanded and showed. But when the Jungle-item is expanded (and the special items are already visible) and I change it to the _leafs itemsSource, and then change the itemsSource back to _roots, all special items have disappeared!! Also, when I do the same as case 2, but first un-expand the Jungle-item again, the special items also disappear. I did a lot of debugging, before posting this question here and come to the following conclusion: Printing on the event: visibility changed, the visibility is set to false for all items that were already visible (that is, when _roots become visible, the special items become invisible (because they were already visible)) So, IsVisible is false for the items, but Visibility = Visible. Which is a bit strange. The problem seems to depend on the use of the _roots list, which in a certain way contain the _leafs. When I change the itemsSource to different lists with special items in it, everything works fine. The hierarchical structure of the _roots make this thing broken. I hope that this is a complete overview of my problem. Help would be appreciated.

  • Internet explorer rejects cookies in kerberos protected intranet sites

    - by remix_tj
    I'm trying to build an intranet site using joomla. The webserver is using HTTP Kerberos authentication with mod_kerb_auth. Everything works fine, the users get authenticated and so on. But if i try to login to the administrator panel i can't because IE does not accept the needed cookies. No such problem with firefox. The intranet site is called "intranet_new" and is hosted by webintranet04, under the directory /var/www/vhosts/joomla/intranet_new/. I have my virtualhost for intranet_new containing this: <Location /> AuthType Kerberos AuthName "Kerberos Login" KrbMethodNegotiate On KrbMethodK5Passwd On KrbAuthRealms PROV.TV.LOCAL Krb5KeyTab /etc/apache2/HTTP.keytab require valid-user </Location> The same is for webintranet04 virtualhost, which is the default pointing to /var/www and contains: <Location /vhosts/joomla/> AuthType Kerberos AuthName "Kerberos Login" KrbMethodNegotiate On KrbMethodK5Passwd On KrbAuthRealms PROV.TV.LOCAL Krb5KeyTab /etc/apache2/HTTP.keytab require valid-user </Location> the very strange problem i have is that if i open http:// webintranet04/vhosts/joomla/intranet_new/administrator IE allows me to login, accepting cookie. If i open http:// intranet_new/administrator, instead, i loop on the login page. Last, intranet_new is a CNAME record of webintranet04. This is only an IE problem. I need: - the admin interface to work with IE - the "kerberized" zone to accept cookie, because i am deploying other programs requiring cookies.

  • Debugging Windows PC freeze

    - by Violet Giraffe
    I have a problem with my computer, would appreciate any hints/ideas. It usually begins not immediately after booting Windows, but at some unpredictable point in time, which doesn't seem to correlate with any specific actions of mine. First sign of a problem is process System starting to consume 25% CPU time steadily. I have a quad-core CPU, so it might be one thread working non-stop. At this point micro-freezes start to occur - screen stops refreshing, but if I have, say, music player running - it continues playing. If I try to do something between the freezes, like open Start menu, it will freeze completely and forever. If I press reset button the PC will shut down and then start cold, as opposed to usual reset behavior (which doesn't include PC shutting down). I have noticed that full restart upon reset is usual for hardware problems, but I think this problem isn't related to at least motherboard-CPU-RAM-videoadapter. It certainly isn't caused by overheating. One very important not is that it seems to be related to Windows hosted WLAN network: I have USB Wi-Fi dongle and have configured a hosted network to share cable Internet connection with Wi-Fi devices. I am not 100% certain there's a strong connection, but in 9 or 10 cases when I enabled the network (by executing netsh wlan start hostednetwork), it did freeze eventually (sometimes within minutes of starting the network, sometimes within hours), and on at least 10 days when I didn't start the network it never froze, no matter how I used the computer). There are no critical/error entries in the events log that I can suspect as being related, only regular stuff like "driver not loaded". I have found no critical/error events that are being logged around the time of freeze occurring and are not logged during normal boot without starting the WLAN.

  • network will not work properly after having run TCP optimizer, but safe mode settings work perfectly. how to restore?

    - by michele
    I was experiencing some issues with my connection while playing online and I tried to optimize it by running TCP optimizer on my PC (Windows 7 64bit professional). I thought maybe the situation could improve. but it didn't. actually, I now get an extremely slow page loading time, probably due to a very low RWIN value of 1024. I understand that Windows 7 has a system to automatically adjust the RWIN value when needed. The setting from netsh is "normal" so I guess something else must be wrong. I tried every automatic tool out there to restore Windows' default values, but I had no success. I currently have what should be labeled as "default values" for everything TCP Optimizer initially changed, but the problem persists. The thing is, I just found out that running Windows in safe mode SOLVES the problem completely. The problem is that as soon as I reboot, I get the same issue all over again. So my question is: is there a way to use SAFE MODE network settings in NORMAL mode?

  • ADSL Modem/Router sometimes hands out incorrect IP addresses

    - by Peter Keevill
    My setup is as follows:- Main ADSL modem / router (switch) configured as DHCP server with address range 192.168.0.25-60 The office machines are configured with fixed IP ( not in the same address pool of course ) and hard wired to this router. A wireless access point ( Router ) is connected to provide Internet access for guests in a separate area. This router is NOT configured as a DHCP server. Wireless authentication is turned off. IP address lease times are set to 4 hours. Sometimes guests are able to connect to the wireless access point but they are not given a valid IP. They get 169.x.x.x addresses. Rebooting their machines does not resolve the problem. The only way to resolve is to reboot the main ADSL/router which is often frustrating for other users who are successfully connected with valid IP and DG. The problem seems to occur more frequently to Apple/Mac guests although it also sometimes occurs with Win machines. I personally use Ubuntu on my Laptop and thus far, never have had any problem connecting and getting a valid IP address in the guest area. One further point of note which may give a clue is that certain guests ( always Apple/Mac ) get lease times of 90 days. However, this does not 'stack out' the number of available addresses and of course, rebooting the router clears them until the next time they login.

  • (Mac Intel) HP PS driver prints in B&W from Adobe Reader after installing Cannon PS driver

    - by John B
    I have a unique problem that leaves me at a loss as to where to start troubleshooting. We have three Macs we use for graphics, two of which are PowerPC and one which is Intel. They are set up to print to an HP 5500dn, but occasionally this printer gets tied up with a massive print job, so I installed the PS driver (iR-PSv1.81MacOSX) for the Cannon C3200 Printer/copier on each of the machines. Both of the PowerPC Macs installed without issue, but the Intel Mac exhibits strange behavior: I've confirmed that while the Cannon driver is installed (whether or not the Cannon is set up for printing in print settings), the HP 5500dn will print in color from Safari, but only prints in black and white from Adobe Reader. The Cannon printer itself has not exhibited any strange behavior As soon as the Cannon driver is uninstalled, the HP 5500dn prints in color from Adobe Reader again. We run a network of Windows PCs, and the 'Mac room' mostly takes care of itself, so we don't have any experienced Mac administrators onsite. The Cannon is capable of Appletalk, but the PS driver seemed easier to work with (and Appletalk is currently disable on the Cannon. I'm not against using the Appletalk compatible drivers, but I would rather use the PS driver if at all possible - I don't want to open up the proverbial can of worms. If someone has any clues or suggestions that would help troubleshoot this problem, I would be grateful. I've already done some googling, but due to the obscure nature of this problem, I haven't been very successful.

  • IPSec VPN using ZyWALL IPSec VPN Client: unable to connect from some providers

    I'm trying to configure an IPSec VPN to one company from my home. The company has SANET internet service provider.

My configuration at home: ISP: Orange Optical connection Terminal: GPON OPTICAL NETWORK TERMINAL G-25E Router: TPLink TL-WR941N --> SPI Firewall Enabled --> VPN - IPSEC Passthrough Enabled I was wondering if the problem could not be on ISP side (that he blocks somehow this connection because in SANET ISP it worked fine) or even in my terminal or router. What could I check? Where could be the problem ?

  • Why can't I physically access my machine after a remote session?

    - by Steve Crane
    I have a Dell Optiplex 960 desktop running Windows 7 64-bit at work. I typically leave it locked rather than logged off when I go home, so that I'm able to remote in from home and continue working if I wish. This is where the problem comes in. If I don't remote in there is no problem and I can simply unlock the next morning. It's when I do remote in that I have a problem. Remote sessions work as expected but when I get to work the next morning the machine appears to have gone into a sleep or hibernate state, from which no amount of mouse moving or keyboard pounding will wake it. The machine is not hanging as remote sessions to it are still possible; it seems that physical access from it's own mouse and keyboard are lost. The only way to gain access is to press and hold the power switch for several seconds until the machine shuts down. Of course this means Windows does not gracefully shut down and after powering up it takes several minutes for the machine to boot and reach the login prompt; presumably while it checks the disk. Has anyone else seen something like this?

The control seems disabled and don't react on mouseclick. Since it is one-time user, they don't wan't to help me with debugging and I cannot reproduce the problem myself. Any ideas why 1000 users have no problem, and 3 are experiencing all controls like they were disabled?
