• Package manager doesn't work anymore

  - by LukaD

  I'm using ubuntu 10.10 and recently my package manager has stopped working because of some problems with dependencies or something. I can't upgrade, install or uninstall anything at all. This is a huge problem. I couldn't find a solution to this with google so I'm asking here for help. This is what apt-get -f install outputs LANG=en_US.UTF-8 sudo apt-get install -f Reading package lists... Done Building dependency tree Reading state information...

• Exchange 2010 sending old Out of Office message

  - by Tatas

  We are just about done with our migration from Exchange 2003 to 2010. I have a user who has been migrated to the new system that is now out on medical leave. He has gone into OWA and set up his Out of Office notification. The good news is that an Out of Office message is sent, the bad news is that it appears to be sending an old outdated message from back when the user was on Exchange 2003, and not honoring the new message set up in OWA. The user has also tried setting this up in Outlook 2010 as well with the same behavior. I have a feeling that this is related to the old public folders (didn't they contain OOF messages?) still lingering around our Exchange org. Any ideas?

• How does Heartbeat determine when to switch to the secondary? Can you force it to switch?

  - by John

  I've been trying to understand exactly how Heartbeat works - I understand how when one server dies, it switches to the backup. But, for me, it also switches when the primary has a large increase in workload. But, it doesn't always switch at the same value. There doesn't seem to much information on the web about how it works. The best I've found is this article. How does Heartbeat determine when to switch to the secondary, and how does it determine when it switch back to the primary? Is this an editable setting, and can I force it to switch between one and the other? Sometimes when Heartbeat will switch to the secondary, it takes a few days or I've even seen two weeks before it switches back to the primary. This is well after the primary traffic has gone down. I'm currently using BlueOnyx, and my Heartbeat settings are: Auto Failback: on Keepalive: 1 seconds Warntime: 10 seconds Deadtime: 20 seconds Initdead: 30 seconds

• nginx proxy pass redirects ignore port

  - by Paul

  So I'm setting up a virtual path when pointing at a node.js app in my nginx conf. the relevant section looks like so: location /app { rewrite /app/(.*) /$1 break; proxy_pass http://localhost:3000; proxy_redirect off; proxy_set_header Host $host; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; } Works great, except that when my node.js app (an express app) calls a redirect. As an example, the dev box is running nginx on port 8080, and so the url's to the root of the node app looks like: http://localhost:8080/app When I call a redirect to '/app' from node, the actual redirect goes to: http://localhost/app

• objects don't snap in browser window

  - by gavin

  I've recently upgraded from XP Pro to Windows7 Pro - In XP Pro (and previous OS versions) you could move Thumbnails around in a window and they would snap/shuffle up/re-order themselves and be viewable as a slide show - it was unbelievably useful - I used it EVERY day, Windows 7 doesn't do this? Is there some setting I can change or is it just not there anymore? I use it for organising photo libraries for archiving - I haven't found any other way of doing this that suits my work. Does anyone know a way to get this feature back? Thanks

• How to display password policy information for a user (Ubuntu)?

  - by C.W.Holeman II

  Ubuntu Documentation Ubuntu 9.04 Ubuntu Server Guide Security User Management states that there is a default minimum password length for Ubuntu: By default, Ubuntu requires a minimum password length of 4 characters Is there a command for displaying the current password policies for a user (such as the chage command displays the password expiration information for a specific user)? > sudo chage -l SomeUserName Last password change : May 13, 2010 Password expires : never Password inactive : never Account expires : never Minimum number of days between password change : 0 Maximum number of days between password change : 99999 Number of days of warning before password expires : 7 This is rather than examining various places that control the policy and interpreting them since this process could contain errors. A command that reports the composed policy would be used to check the policy setting steps.

• How do I sync beyond 30 days with BES

  - by Kez

  BES only syncs the last 30 days worth of calendar appointments. I need to change this to sync more than 30 days, e.g. 6 months for example. I read a workaround which involves disabling the wireless sync, syncing with the Blackberry Desktop software and then re-enabling the wireless sync. This would not work, as the 30 day setting would still apply to calendar appointments going forwards. How can I set BES up to sync more than 30 days worth of calendar appointments?

• IIS + PHP + Page with lots of images = Intermittent 403 errors

  - by samJL

  I am using an up-to-date Server 2008 R2 Datacenter, running IIS 7.5 and PHP 5.3.6/FastCGI On PHP pages with lots of images (60+), some of the images fail to load It is not always the same images-- on each page refresh an image that worked previously may not load, while an image that did not now does Looking at the Net tab in Firebug reveals that the failing image requests are 403 errors All of the images are located on the server in question, and the images directory has the correct permissions I believe this problem is the result of a limit on requests All of my attempts at researching this problem point to maxConnections setting in IIS, yet mine is set at the highest/default of 4294967295 (maxBandwidth too) I am also running a ColdFusion site on the same IIS installation, and it does not suffer from 403's on pages with lots of images I am left thinking that there is another connection limit (in PHP or FastCGI?) overriding the IIS connection limit I don't see anything that looks like a request limit in the php.ini, what am I missing? Any help would be appreciated, thank you

• How can I make smoother upwards/downwards controls in pygame?

  - by Zolani13

  This is a loop I use to interpret key events in a python game. # Event Loop for event in pygame.event.get(): if event.type == QUIT: pygame.quit() sys.exit() if event.type == pygame.KEYDOWN: if event.key == pygame.K_a: my_speed = -10; if event.key == pygame.K_d: my_speed = 10; if event.type == pygame.KEYUP: if event.key == pygame.K_a: my_speed = 0; if event.key == pygame.K_d: my_speed = 0; The 'A' key represents up, while the 'D' key represents down. I use this loop within a larger drawing loop, that moves the sprite using this: Paddle1.rect.y += my_speed; I'm just making a simple pong game (as my first real code/non-gamemaker game) but there's a problem between moving upwards <= downwards. Essentially, if I hold a button upwards (or downwards), and then press downwards (or upwards), now holding both buttons, the direction will change, which is a good thing. But if I then release the upward button, then the sprite will stop. It won't continue in the direction of my second input. This kind of key pressing is actually common with WASD users, when changing directions quickly. Few people remember to let go of the first button before pressing the second. But my program doesn't accommodate the habit. I think I understand the reason, which is that when I let go of my first key, the KEYUP event still triggers, setting the speed to 0. I need to make sure that if a key is released, it only sets the speed to 0 if another key isn't being pressed. But the interpreter will only go through one event at a time, I think, so I can't check if a key has been pressed if it's only interpreting the commands for a released key. This is my dilemma. I want set the key controls so that a player doesn't have to press one button at a time to move upwards <= downwards, making it smoother. How can I do that?

• How do I get a 300Mbps connection over 802.11n?

  - by Daniel Schaffer

  I just bought a new wireless setup, consisting of a Cisco E2000 router, Edimax 7718un USB adapter for my laptop and an Edimax 7728in PCI adapter for my HTPC (which isn't in a location I can run cat5 to). I have to stay in the 2.4GHz band because I have an iPhone and a Wii that will need to connect. I'm aware that 11g devices will drop speeds for 11n devices, but they aren't connected yet. The fastest connection I've been able to get, with the router within 5 feet of either the laptop or HTPC is 144Mbps. The router has settings for "20MHz" and "Auto (20 MHz or 40Mhz) channel width, which I've set to the "Auto" setting. I haven't been able to find anything similar for either of the Edimax adapters. This is the first I've dealt with 11n, so I'm not even sure what else could be causing a problem. How do I get up to 300Mbps, or at least a fair bit closer?

• How do I setup Apache with FastCGI and Ruby?

  - by sdellysse

  I've been reading alot of forum posts, tutorials, etc., about setting up apache under linux with fastcgi. I'm trying to run fcgi for some of my ruby development (not rails), but I figure it should apply to any language. Please note that I already have apache, fastcgi, ruby-fcgi, and the like already installed on my web box. Conceptually, I'm having a hard time with it. Does apache spawn the specified fcgi processes as needed? Do I start them along side apache? Basically, I'm trying to get to a point where I am able to ask the proper questions, so apologies if the title is misleading.

At that point I get the error: Could not complete Setup. Please try again. Whats going on here? I've uninstalled Virtual PC and xpmode, and reinstalled in several different orders, no luck. Is there some log file that will tell me whats happening? Theres nothing showing up in the Event log that I can find. How can I fix this?

• Any programs for getting rid of .DS_Store files? [closed]

  - by mcandre

  Possible Duplicate: How to prevent Mac OS X creating .DS_Store files on non Mac (HFS) Volumes? I dual boot between Mac and Windows. When I browse my Windows partition with Finder, it drops little .DS_Store turds all over the folders. They show up when I boot back into Windows. Right now I've got one on my Desktop, sigh. Are there any (free) programs I can use to stop this from happening? I know, I know, there's a Finder setting to stop dropping .DS_Store files on network drives, but my local Windows partition is NOT a network drive.

• Printer Canon MP540 succesfully added finally but doesn't print? (Attached Debug log)

  - by NES

  i tried to setup my printer in Ubuntu 10.10. I had to use special guide to install because Canon used libcupsys2 in its packages and ubuntu expects libscupsys i followed this guide in reference to this advice. The first problem was this one (the ubuntu "add printer dialog asked for root credentials". The suggested workarout in Launchpad to create a root password worked. Now i added the printer. It's available for printing. Then i got an error message "cups insecure filter" which prevented me from printing. That could be solved by setting the need root rights in the /usr/lib/cups/filter/ directory. The error message disappeared after restarting cups service. Now it should work but it doesn't. The main problem is now, the printer seems to be proper setup but when i try to print a document, the printer icon appears for short time in gnomepanel. There's a printing job in Queue which got completed, but the printer doesn't print. I attached the Debuglog provided by printer error control, had to upload to another site, since it was to big in the question body here. Perhaps someone can identify the problem with it? Note: i know that it once worked fine with an older release of Ubuntu, but not sure which version this was.

• Protecting a webpage with an authentication form

  - by Luke

  I have created an employee webpage with a lot of company info, links, etc., but I want to protect the page because it contains some confidential company information. I am running IIS7.5 on Windows Server 2008 R2, and I already have the site setup as a normal, non-protected site. I want all active directory users to have access to the site. This is not an intranet site, it is exposed to the internet. I tried setting it up using Windows Authentication, but I had problems with multiple login prompts, etc. I just want a simple form for users to enter their credentials and have access to the site, and I need it to query the AD for login. I've searched the web for a guide on this, but I can't seem to find one that fits my situation. This is not a Web App. It is just a simple html site. Does anyone have any suggestions or a link to a guide on this? Thanks so much! -LB

• Make Outlook run rules on non-inbox folders automatically

  - by tHeSiD

  I currently have my Outlook setup with Gmail. I have a couple of rules that I have defined which run on different folders (lables) in my account. I have filters already setup in GMail which will make emails skip the inbox and put them in the respective folders. Whenever I get a new email, in those folders, my rules are not run (they are just for setting categories). I have to run them manually. I think its because the emails don't come to the inbox first but directly into the folder. Is there anyway to make outlook run rules automatically on those folders? A scheduled run should also be fine.

• windows 8 on macbook locks after 2 mins despite high performance settings

  - by Mark

  I am running my Macbook Prop as a Windows 8 machine using bootcamp and for some reason, when I leave the keyboard/mouse alone for 2 mins it locks the PC (i.e. goes to the lock screen). I have (of course) checked the power settings and I can assure you that it is not set to these settings. I did notice that when I added my work's Mail Account the computer asked me to accept some group policy settings, which I did, so I suspect that this is a group policy setting, but I cannot find it. Can someone help? P.S. I have searched these forums first, and this is different to the PC going to sleep once locked, this is locking while logged in after 2 mins. Thanks.

• How can I replace red in an image with a certain shade of gray?

  - by Malcolm Frexner

  In this image I have to change red to grey: I know I can just set the saturation to zero, but then the result is a grey that is to dark. I could just change the brightness, but that would also change the left lower part of the picture: Is there an adjustment that only works on the red parts of the image? I can't use a selection, because the setting has to be applied to lots of images. EDIT I tried to use "replace adjustment tool", but that did not work well for the shdows and bright parts of the image, even with the largest fuzzines. I used blue as the replacement colour, to have a better impression of what it does.

• Any ramifications to disabling ClearPageFile

  - by user34710

  I am runing a Dell XPS 15z with a quad core I7, 8gb ram, 7200rpm hdd, windows 7 ultimate. My laptop was taking around 3 minutes to shut down, which seemed far too high to me. I did a bit of investigation, and it seemed that the ClearPageFile reg entry was set to 1, meaning that upon shutdown my pagefile.sys was being cleared before actually shutting the machine down. When I disable this setting, my laptop shuts down in about 20 seconds - clearly a big gain. My question is, are there any side effects of having this turned off (other than the security risk of the HDD being stolen, and still having any important info that was in the RAM up for grabs)?

• Possible to load entries into hosts.deny from text file?

  I have around 96 million IP addresses that I have collected and routinely validate to be VPN providers, proxies, etc. I want these blocked. Currently, I am including the list formatted like deny ip; in nginx and that works perfectly. I want to use this list on another server, but nginx isn't an option, and I don't trust apache to handle this without slowing down. Is there a way to load this list into hosts deny via some command like aclexec or something? Are there other alternatives like setting up a DNSBL or using hosts.deny in conjunction with one?

• How can one make the title bar text/buttons have better contrast on dark colors in Windows 8?

  - by zeel

  When Windows 8 color setting are set to a very dark color, such as black or navy blue, the title bar text and the minimize/maximize buttons are nearly invisible. This makes dark colors difficult to work with. In Windows 7 there was an advanced color options, this is gone in 8. The registry keys associated with this seem to still be present, but they have no effect. Is there a way to change this? Or a third party application that can do it? I don't want to use the ugly high contrast theme, I want to use the nice Win 8 theme with a dark color.
