• Acer Aspire 5532 crashes with no warning

  - by keenan

  I have an Acer Aspire 5532. I don't have more specs off the top of my head but from what I've looked up it has all the factory stock stuff in. My keyboard is completely shot and doesn't work at all. It was working fine for quite a while, however I go to get on it Thanksgiving night and all of a sudden it just crashes with no warning. I try to restart it and it beeps 3 times with about 15 seconds in between each beep. After that it will go to start up and get to the log in screen, and about 3 minutes later it will crash again with absolutely no warning. The same thing happens every time I try to start it up. I've taken it completely apart and cleaned the fan and all the airways. I made sure all the connections are good (or at least all the ones that I can get to above the mother board), put it back together and I get the same problem.

• how to stop deferred emails

  - by Will K

  I have a postfix mail gateway. At the same time, every other host is set to use this gateway as the relay. We have some automated outgoing emails sent from some hosts. I believe the gateway trys to send a deferred status back to the system started this. But that system is a null client, which sends but not receive any email Is there anyway to stop sending the deferred status? e.g. postfix/smtp[35725]: 2F6A155C256: to=, relay=none, delay=260862, delays=260862/0.01/0/0, dsn=4.4.1, status=deferred (connect to orange.mydom.com[192.168.1.5]:25: Connection refused) Thanks

• php apache unknow 500 error

  - by JohnathanKong

  I currently have an error with my apache/php installation on a centos system. I checked the log files in /var/log/httpd and in my logs directory as specified in my virtual host file, but they are not getting populated with errors. I've also set php to log errors, through the php.ini, to the /var/log/httpd/ but the error file is not getting created. When I setup the display_errors = On in the php.ini all I get is a blank screen. this is a git controlled project that is running off of an ubuntu server that works perfectly, so there is something missing from this server. My question is, is there any way I can get more info on the error that I am getting? I just need something that I can trace back. I am using a codeigniter framework, so for me to trace through the code will take days. Thanks!

• Setting up Relays in Windows

  - by Auditor

  I'm trying to setup a pivoting relay with netcat on Windows, replicating a scenario easily possible by using pipes in Linux. Assume machine A can route to machine B and machine B can route to machine C. If machine A needs to route to machine C, we can setup a relay on machine B which can pivot data back and forth for us using command redirectors and spl filetype pipe. Assume: machine C has nc -nlvp 3306 -e cmd.exe machine A has nc -nlvp 80 IF machine B was Linux we could have done mkfifo pipe nc -nv 127.0.0.1 80 0<pipe | nc -nv 127.0.0.1 3306 1>pipe so on machine B if we do nc -nv 127.0.0.1 80 0<&4 | nc -nv 127.0.0.1 3306 1>&4 Per this site, I should be able to achieve what I can with Linux, but unfortunately it is not working.

• How can I stop Pages from bolding/italicizing ordered list item numbers/letters?

  - by donut

  I'm writing a long, technical document that uses a lot of ordered lists in Pages '09. Often when I bold or italicize the first bit of text I type for a list item it Pages applies the same styling to the letter or number of that list item. It's been doing this for the first 13 pages I've written and now I've found out that I need to undo that. Is there any place to change this behavior or easily fix existing list item numbers/letters that are styled? The only way I've found is to select the whole list item (all of its content) and removing teh styling (un-bolding and un-italicizing) and then going back in and re-applying my stylings to its content. Definitely not ideal.

• Provide A Scrolling "Camera" View Over A 2D Game Map

  - by BitCrash

  I'm in the process of attempting to create a 2D MMO type game with Kryonet and some basic sprites, mostly for my own learning. I have the back end set up great (By my standards) and I'm moving on to actually getting some things drawn onto the map. I cannot for the life of me figure out a solid way to have a "Camera" follow a player around a large area. The view pane for the game is 640 x 480 pixels, and each tile is 32x32 pixels (Thats 20 tiles wide and 15 high for the viewpane) I have tried a couple things to do this, but they did not seem to work out so well. I had a JScrollPane with 9 "Viewpane"-sized canvases in it, and tried to have the JScrollPane move in accordance with the player. The issue came when I reached the end of the JScrollPane. I tried to "Flip" canvases, sending the canvas currrently drawing the player to the middle of the 9 and load the corresponding maps onto the other ones. It was slow and worked poorly. I'm looking for any advice or previous experience with this; any ideas? Thank you! Edit and Clarification: I did not mean to mention Kryonet, I was merely providing peripheral information in case there was something that would help which I could not foresee. Instead of having an array of 9 canvases, why not just have one large canvas loading a large map every once in a while? I'm willing to have "load times" where as with the canvas array I would have none (in theory) to give the user a smooth experience. I could just change the size and location of the map with a modified setBounds() call on the canvas in a layered pane (layered because I have hidden swing items, like inventories and stuff) I'll try it out and post here how it goes for people asking the same question.

• Debian doesn't boot after removing secondary hard drive

  - by Daveel

  In the beginning I had Debian 6 running on one hard drive (/dev/sda1). Then I decided to keep all my stuff(pics, videos, etc..) in another slave hard drive (/dev/sdb1). So sda1 has Debian OS sdb1 doesn't contain any OS files I have made it to mount automatically by adding a row in /etc/fstab (UUID and directory to mount to) Time have passed and when I tried to change that secondary hard drive with another hard drive with bigger capacity, for some reason Debian won't boot (just itself sda1) after removing secondary hard drive (sdb1) But if I plug sdb1 back, it boots just fine. I tried to comment line out from /etc/fstab, so it doesn't mount And also did update-grub after umount /dev/sdb1 What's the right way to remove hard drive secondary hard drive?

• How to correct a junior, but encourage him to think for himself? [closed]

  - by Phil

  I am the lead of a small team where everyone has less than a year of software development experience. I wouldn't by any means call myself a software guru, but I have learned a few things in the few years that I've been writing software. When we do code reviews I do a fair bit of teaching and correcting mistakes. I will say things like "This is overly complex and convoluted, and here's why," or "What do you think about moving this method into a separate class?" I am extra careful to communicate that if they have questions or dissenting opinions, that's ok and we need to discuss. Every time I correct someone, I ask "What do you think?" or something similar. However they rarely if ever disagree or ask why. And lately I've been noticing more blatant signs that they are blindly agreeing with my statements and not forming opinions of their own. I need a team who can learn to do things right autonomously, not just follow instructions. How does one correct a junior developer, but still encourage him to think for himself? Edit: Here's an example of one of these obvious signs that they're not forming their own opinions: Me: I like your idea of creating an extension method, but I don't like how you passed a large complex lambda as a parameter. The lambda forces others to know too much about the method's implementation. Junior (after misunderstanding me): Yes, I totally agree. We should not use extension methods here because they force other developers to know too much about the implementation. There was a misunderstanding, and that has been dealt with. But there was not even an OUNCE of logic in his statement! He thought he was regurgitating my logic back to me, thinking it would make sense when really he had no clue why he was saying it.

• Windows 7 Extend C Volume to Unallocated Space

  - by user327777

  a while back I installed Ubuntu and then later uninstalled it by I think deleting the partitions and recovering the windows 7 boot loader. I am not that experienced with partitioning yet. As you can see here there are two partitions that are now unallocated. The 9gb one is a recovery or something that came with the computer. How can I extend my C partition to use both of those? I do not want to have that much storage just wasted sitting there. Currently when I right click on C and hit extend the wizard pops up but there is no available space to extend. http://i.imgur.com/VxEkdyR.png http://i.imgur.com/DdFZWX9.png Thanks everyone!

• User cannot book a room resource

  - by bakesale

  Im having a problem with a specific user not being able to book a room resource. No error message is generated at all. The user attempts to add the room as a meeting resource and it simply doesnt register with the resources calendar. I have tested the resource with other accounts and other rooms for this user but it is only this room that is having issues for this user. This Exchange server was migrated from 2007 to 2010. All rooms except for the problem room were created back on Exchange 2007. This new room was created with Exchange 2010. Maybe this clue has something to do with the problem? This is a paste of the mailboxes folder permissions [PS] C:\Windows\system32Get-MailboxFolderPermission -identity cbr125:\calendar RunspaceId : 448ab44a-4c2a-4403-b46c-fce1106c0823 FolderName : Calendar User : Default AccessRights : {Author} Identity : Default IsValid : True RunspaceId : 448ab44a-4c2a-4403-b46c-fce1106c0823 FolderName : Calendar User : Anonymous AccessRights : {None} Identity : Anonymous IsValid : True

• How can I use my Windows 7 computer to share WiFi connection with PCs that don't have wireless?

  - by Tom Auger

  Long story short: modem and wireless router are downstairs and we're having a LAN party where some visitors don't have wireless. There's no way to run the length of cabling required, so looking for options. My Windows 7 Home Premium PC has a wireless-n connection, and I'd like to see if I can use it as a "hub" or switch of sorts, running an ethernet cable out of the back and into a switch, then splitting off to the other PCs. Is this an option? I know with Internet sharing, you can set up your PC as a wireless access point, but I want to do the opposite.

• How do I change the .NET Framework version of a virtual directory without the ASP.NET tab?

  - by Brandon

  I have a website running v2.0 but I want the virtual directory running under it to use v4.0. I've already set the virtual directory as an application and gave it it's own application pool. The server is running Windows Server 2003 SP2 (64-bit). However it has the Enable32BitAppOnWin64 flag enabled which means the ASP.NET tabs on the properties dialog of the websites/virtual directories are missing. .NET 4.0 is installed, aspnet_regiis -lv lists the 32-bit and 64-bit versions of .NET 2.0 and .NET 4.0 and the Web Server Extensions are enabled. I can't disable the Enable32BitAppOnWin64 flag to get the ASP.NET tab back, so is there a way to do this from the command line without potentially breaking something? I ran aspnet_regiis -lk to find the paths so I could try aspnet_regiis -sn, but it only returns one record W3SVC/ 2.0.50727.0 (There are 3 separate websites and a virtual directory running on the server though) How can I change the framework version of the virtual directory without the ASP.NET tab?

• Thunderbird: "Could not initialize the application's security component" [closed]

  - by user unknown

  In Thunderbird, on startup, I get the error message: "Could not initialize the application's security component" The message continues to check permissions of the profile, and free disk space. df -h shows, that I have 19G free disk space. find . -not -perm -644 -not -perm -600 -ls shows: No file without rw-permissions for me. Before the error occured, thunderbird worked well. But I changed my main mail-account. I had two, let's call them A and B, and used mainly A, but now I wanted to deaktivate it, and receive and send automatically via the second. I Had problems moving the filters from inbox A to inbox B (missing copy-functionality). In the web, I found (mollazine) hints, to move key3.db, cert8.db and secmode.db out of the way, but it didn't work for me. Another hint was to uninstall Quickcam(?. sic!), but I don't have Quickcam. A third to recreate the profile, but I have subdirectories, filters, addressbook, groups - mails back to the year 2003. I don't want to risk the loss of data. The whole errormessage is: Could not initialize the application's security component. The most likely cause is problems with files in your application's profile directory. Please check that this directory has no read/write restrictions and your hard disk is not full or close to full. It is recommended that you exit the application and fix the problem. If you continue to use this session, you might see incorrect application behaviour when accessing security features. When I open the error-console, it is empty.

• Thunderbird 3.0 - how to prevent new message indicator from clearing?

  - by Joe Casadonte

  I just installed Thunderbird 3.0 and there are a few things driving me batty. When new email is delivered it has a faint star to the left of the subject (this is different than the new star column thing). In the old days (i.e. last week) the new message indicator wouldn't go away until I read the message or left the folder and returned. Now, as soon as I do anything with any email message, all new message indicators are cleared. How can I go back to the old behavior?

• Slot load DVD burner options for standard desktop case

  - by Michael Kohne

  I need a new DVD burner (internal) for my father-in-law's computer. He's apparently broken the current one - he forgot to push the tray back in after doing something and hit it with his chair. Given this, I'd like to get him a slot-loading DVD burner, so as to avoid the problem entirely. I need an internal device, and I'll be mounting in a 5 1/4" bay. He doesn't need any super-spec device - as long as it can read/write all the standard formats, it's good. I see a few options at newegg.com, but they all have mixed reviews. Are there any out there that are generally seen as reliable? How does one go about mounting slimline devices in a standard 5 1/4" bay? Is there a standard faceplate kit for that?

• Why would one server be sending DUP ACK packets to one PC, which is responding with HTTP RST packets?

  - by IronicMuffin

  I'm not a network profressional, so please excuse any wrong language. I was debugging why my DNS traffic was a constant 160Kbps on our corporate network. I opened up a wireshark trace, and I see one PC of a coworker broadcasting HTTP [RST] packets to one of our DMZ servers at the rate of 1000 a second. He restarted his machine, and as soon as it went offline, the server started broadcasting [DUP] [ACK] packets, until he came back online. It then resumed the HTTP [RST] packets. Apparently this server has been doing this kind of behavior since it went live. I believe it did this with a printer and an access point as well. Can anyone explain why this behavior is occurring? Any solutions? The initial research was done because there have been "bandwidth issues" and I wonder if this is contributing.

• Monitor dectecs wrong display mode

  - by user292449

  I am running into an issue with 14.04. I have two monitors. the fist one is a 19 inch LG that runs off DVI at 1440x900. It seems to function just fine. The second is a 23 inch LG that should run at 1920x1200. It has been plugged in with both a HDMI to HDMI cable and a DVI to HDMI cable. It seems to be stuck in "I am displaying for a DVD player in 1080p mode" or some such. I had this issue with windows a long long time ago and eventually it just went away. I can set the screen display to 1920x1200 with the generic X drivers but I am a gamer and would like to use the Nvidia drivers since they deliver better performance. When I switch to the Nvidia driver I can set the resolution to 1920x1200 but the screen seems to be up and to the left with a black border down and to the right. If I switch back to the default X driver after this the screen remains stuck in the up and to the left mode. Any help would be wonderful.

• Files beginning with "._"

  - by Cliff_31

  Sometimes when my wife works on photos in Photoshop on her Mac, what she gives me back are all the photos I took, with their .jpg extensions in place, as well as a set of "ghost" files. That is, for every photo, there is an evil twin whose file name is the same ... except that it begins with "._". Also this ghost file are sort of "grayed-out" and don't open when double clicked. I suspect they are hidden files, (I have set windows to show all hidden files) but what find of hidden file -- on that, I'm clueless. I just delete these files and never have a problem with the photo (.jpg) files, but still I'm dying to know; what are they? Thanks

• Performance Drop Lingers after Load [closed]

  - by Charles

  Possible Duplicate: How do you do Load Testing and Capacity Planning for Databases I'm noticing a drop in performance after subsequent load tests. Although our cpu and ram numbers look fine, performance seems to degrade over time as sustained load is applied to the system. If we allow more time between the load tests, the performance gets back to about 1,000 ms, but if you apply load every 3 minutes or so, it starts to degrade to a point where it takes 12,000 ms. None of the application servers are showing lingering apache processes and the number of database connections cools down to about 3 (from a sustained 20). Is there anything else I should be looking out for here?

• Can't boot to Windows 7 after installing Ubuntu 11.10

  - by les02jen17

  Here's what happened: I have 2 HDDs. 1st HDD is partitioned like this: C - Windows 7 D* - Empty drive where I installed Ubuntu E - Personal Files F - Personal Files 2nd HDD is partitioned like this: G - Personal Files *the D partition is originally part of the C partition. I resized it (using Easus Partition Master in Windows) and defragged it prior to installing Ubuntu. I installed Ubuntu by booting to the Ubuntu Secure Remix CD, and chose the D partition to install Ubuntu. I did not create a swap drive, and I mounted the / to the D partition. I didnt know where to mount the others, so I just thought by mounting the / to D, it would be okay. After the long installation, upon rebooting, I can't access Windows AND Ubuntu. I get an infinite bootloop and eventually the choices to boot to Safe Modes, Last Known Good Configuration and Start Windows normally. After failing in all of them, I placed the CD back and ran the Boot Repair. I chose the MBR 1st, it didn't work. I then chose the GRUB 2nd and now I was able to boot to the Ubuntu I installed, but not to my Windows 7! I'm using my newly installed Ubuntu while writing this. I hope you can help me. I did the best I could! Here's the link to the boot repair log: http://paste.ubuntu.com/919354/ Thanks in advance!

• What is the easiest way to make a backup of an entire hard disk

  - by Solignis

  Hi there, I got myself a dell laptop from the local computer store. Its a used machine with Windows Vista Home Basic on it. I want to load Ubuntu Desktop 10.10 though so I can do perl development. BUT I want to keep a copy of the entire harddrive with the dell utility partition and Windows Vista in case I want to go back. I was thinking I could image the drive but I not sure what to use, I don't have Ghost or anything, Someone had told me about Clonezilla. Would that work for me? Is it hard to use? Also I want to burn the data to a DVD or something more storable than a harddisk.

• ADF Hands on Training &ndash; Prerequisites for 22nd March 2011

  - by Grant Ronald

  For those of you coming to the ADF Hands on training on the 22nd March in London, there was a link to the prerequisites.  Unfortunately, in a reshuffle of content on OTN, this page was removed.  So, over the next day or so I’m hoping to the pull together the relevant information into this blog post.  So keep checking back! Firstly, you need to being your laptop with you to do the hands on exercises.  No laptop, no hands on. Recommended 2GB RAM running Microsoft Windows XP SP2, 2003 Server SP2, Vista (32 bit only), Windows 7 or Linux or Mac 2GHz Processor (less will be acceptable but slower) Mozilla Firefox 2.0 or higher, Internet Explorer 7 or higher, Safari 3.0 and higher, Google Chrome 1.0 or higher Winzip or other extracting software Adobe Acrobat reader Flash (if you want to see dynamic graphs in your application) As for software, you will need have installed JDeveloper 11g.  The hands on instructions are based on 11.1.1.2 (or is it 11.1.1.3)! anyway, either of those or 11.1.1.4 would be required. You also need an Oracle database on your machine and access to the HR schema (which should be unlocked).  Don’t expect to have access to a network and VPN to a database. A simple test, unplug your laptop from your corporate network, run up JDev  and select File –> New –> Database connection and make sure you can connect to HR database and see the Emp/Dept etc tables.  If you can do that, you should be good to go. I would strongly recommend ensuring you have this in place before you arrive on Tuesday. Look forward to seeing you there.

• When XP is asleep for a long time LAN reports code 43, gives up the ghost.

  - by seeanimal

  This one's got me stumped. Whenever the system is asleep for a long time, e.g overnight, the LAN driver reports error code 43 ("a problem") and turns itself off. This has being going on for months, but I never caught the problem until now. The owner merely shuttles back to a restore point I set her when the machine worked. Previously (without knowing exactly what was happening) I have tried everything to resolve this. Manually resetting the TCP/IP, fiddling with the driver Wake From LAN settings, DIFFERENT drivers, etc. etc. The solution is easy, uninstalling and reinstalling the driver. Understandably, though, the user is uncomfortable with this operation and the problem persists. What's causing it and how to stop it recurring? Any ideas? Thanks in advance to this great community. XP home SP3, Marvell Yukon 88E8056 PCI-E Gigabit Ethrnet Controller, version 10.22.7.3 (yk51x86.sys)

• Website only displays correctly in IE using compatibility mode?

  - by user21318

  As the resident "IT Whiz" at work (ie: I know how to use a computer) I've been asked to develop a website for our small business. I've altered a wordpress theme for the time being and the company is very happy with the results. The only problem I am having with it at the moment is that for some reason the website does not display correctly and Internet Explorer unless I run it in Compatibility Mode. The main problem that I have is that my menu "slider" (it rotates pictures with links to articles etc) does not display at all, neither does the top menu they are just blink text based links. Even with Compatibility Mode enabled the slider and menus come back but the page is not centered unlike on both Firefox and Chrome. My googling has suggested the most common cause of this is old code but I'm not sure where to be looking. Is it likely in the css file or the actual php? Also any ideas on how to trouble shoot the cause of this? As in is there some dev tools or debugger I can use that would highlight "broken" code for me?
