• How to suppress Terminated message after killing in bash?

  - by emergence

  How can you suppress the 'Terminated' message that comes up after you kill a process in a bash script? I tried set +bm, but that doesn't work. I know another solution involves calling 'exec 2 /dev/null', but is that reliable? How do I reset it back so that I can continue to see stderr? Thanks

  - by openid_kenja

  When our server comes up we need to check a file to see how the server is configured. We want to search for the following string inside our /etc/aws/hosts.conf file: MYSQL_ROLE=master Then, we want to test whether that string exists and use an if/else statement to run one of two options depending on whether the string exists or not. What is the BASH syntax for the if statement? if [ ????? ]; then #do one thing else #do another thing fi

• Hide 'Your profile could not be opened correctly'

  - by B. Roland

  Hello! I have a small public internet cafe, with Ubuntu 10.04 and 10.10. I'm using Google Chrome 7.0.517.44 (64615), with AutoScroll - Version: 2.7.5; AdBlock is removed because of high CPU loads, and unconfortable speed of machine. "Your profile could not be opened correctly" error is displayed: This image is only an illustration. The reason is that I changed permissions of some config files, to don't remember the history, there are no setting in options, to don't use history. I've been removed write permission to: ~/.config/google-chrome$ find . -group nopasswdlogin ./Default/Archived History ./Default/History ./Default/Visited Links When I solved all of my problem, I'll remove some other write permission, this is a public place. What methods are known to HIDE this message? Thanks!

• How to profile LINQ to Entities queries in your asp.net applications - part 1

  - by nikolaosk

  I have been teaching ASP.Net and EF in one of my classes and I have been asked on the various ways we can profile database activity. Everyone that I know that uses EF as its data access layer has the same question. "How can I see the T-SQL code that the LINQ to Entities engine generates on the fly?" I know a lot of people use VS studio built-in visualisers but that is not enough. A lot of developers use SQL Server Profiler. That is also a good solution since we can see the queries(generated from...(read more)

• Keep user and user profile in different tables?

  - by Andrey

  I have seen in a couple of projects that developers prefer to keep essential user info in one table (email/login, password hash, screen name) and rest of the non essential user profile in another (creation date, country, etc). By non-essential I mean that this data is needed only occasionally. Obvious benefit is that if you are using ORM querying less fields is obviously good. But then you can have two entities mapped to same table and this will save you from querying stuff you don't need (while being more convenient). Does anybody know any other advantage of keeping these things in two tables?

• How to login after modifying ~/.profile wrongly

  - by Jasper Loy

  I did something very silly a few weeks ago. I wanted to add a path so that the OS could find some manually installed executable. Instead of typing 'PATH=xxx:$PATH;export PATH' at the end of the ~/.profile file where xxx is the directory in which the executable lies, I accidentally typed 'PATH=xxx;export PATH'. After I logged out I was unable to login anymore as I probably messed up the whole PATH variable and reinstalled the whole thing. My question is: is there a way of rectifying the situation if I happen to add the path wrongly (hopefully not!) in future?

• Clone User Profile with Encrypted Home Folder

  - by doublerainbow64

  I'd like to clone my user profile on my local machine. I'd like to do so, just to keep all the preferences and not to have to redefine all of them manually. I've tried this, but when I login, it will just return to KDM login screen. BTW I'm using Kubuntu 14.04. What might be interesting: I have encrypted my home folder. Does this make any difference? I've also tried to copy the contents of .kde folder into /etc/skel, but this had no effect. Thank you very much in advance, doublerainbow64

• XNA Framework HiDef profile requires TextureFilter to be Point when using texture format Vector4

  - by danbystrom

  Beginner question. Synopsis: my water effects does something that causes the drawing of my sky sphere to throw an exeption when run in full screen. The exception is: XNA Framework HiDef profile requires TextureFilter to be Point when using texture format Vector4. This happens both when I start in full screen directly or switch to full screen from windowed. It does NOT happen, however, if I comment out the drawing of my water. So, what in my water effect can possibly cause the drawing of my sky sphere to choke???

• Good places to submit a business profile?

  - by Rob

  We have a new graphic/web design site that we've created and we'd like to give it a boost in terms of back links. What are the obvious places to submit a website to achieve some good back links? And what would be the recurring work load (if any) that those back links would need? Are there any good industry specific websites we could submit a profile to? E.g Twitter, would need constant interaction and new content with back links to the website. UPDATE: I've always felt it's worth it but after several years trying to submit different websites, I've never successfully managed to get a site into DMOZ!!

• Deleted, then added user w/ same name, now logs on w/ temp profile

  - by labyrinth

  I am a new admin at a high school lab and am trying to spearhead separation of normal IT accounts from IT admin accounts. I made my normal account (e.g. ITuser) and an admin account (e.g. ITuser-adm) on the server (Win Server 2008 R2). I used both accounts on my my main desktop for about a day, but decided I hadn't set up the admin account correctly. I deleted the my admin account, then made a new one with the same name. The problem is that on my main desktop (Windows 7 Pro), whenever I log in with my admin account, it gives the following errors: Windows has backed up this user profile. Windows will automatically try to use the backup profile the next time this user logs on. (Error 1515) Windows cannot find the local profile and is logging you on with a temporary profile. Changes you make to this profile will be lost when you log off. (Error 1511) This is more of a nuisance than anything for me, I just thought I could use the same name for a user account I'd just deleted since they would have separate SSIDs anyway. If it's less trouble, I could just make a new admin account. Or I could just keep using it as is since I don't need to be saving anything locally anyway and the typical folder redirects work fine. I'm just curious and want to understand what's going on. There are no errors listed regarding the registry.

• AppArmor Profile for PowerDNS

  - by Cory J

  I am currently working on a new authoritative nameserver using powerdns on Ubuntu 8.04 LTS. I'd like to have AppArmor protecting this service like it did with bind, but when I look in /etc/apparmor.d/, there was no AppArmor profile for this service installed by default. Any experienced pdns admins know what all files pdns accesses, so I can define a profile? Or better yet, does anyone HAVE a profile for pdns? Many thanks for any suggestions.

• Network profile reverts to 'Unidentified' following Windows Update reboot

  - by user140575

  I have searched high and low for a solution to this problem. I have multiple servers running Windows 2000 Server as well as Windows Server 2003, 2003 R2, and 2008 R2. All of these servers are on the same Active Directory domain. The servers run showing the network profile as Domain Network, which is fine and correct. However, when a Windows update is installed, the server changes the profile to Unidentified Network once it has rebooted. This then doesn't allow any traffic to the server. For security reasons, we can't turn the firewalls off for. The only way to fix the problem is to physically be in front of the machine and work on it to change the profile back. Once the Profile has been reinstated to the Domain profile, it will be fine until the next month's update. This happens on all the Windows software mentioned above. The machines are not all identical, so it's not a hardware problem either. If anyone can help I'd be very grateful.

• Moving Windows 7 profile to new user

  - by Kevin Grossnicklaus

  I have a laptop which I've been using as part of a corporate network with an AD login (and associated local profile). The laptop is loaded with Windows 7 Ultimate. I need to remove the laptop from this domain and, to start this process, I have already configured a local user on the box for me to use moving forward (granting this user the same local admin rights as the AD user). I'd like to migrate all the files, settings, etc from the local AD profile to the new non-AD profile. Is there a simple way to do this? Anything built into Win 7? As far as basic files I can probably just manually copy all the documents, pictures, music, desktop, favorites, etc... But is there a more streamlined way to move profile information? -Kevin

• Lost "VGA Display" color profile in OS X

  - by Justin Love

  OS X Display settings used to have a color profile named VGA Display, which I found quite usefully for finding color problems before hooking up a projector. Currently, this profile (along with a number of others I've collected from projectors in the past year) is not available. I'm currently OS X 10.6.6 and my best guess is the profiles got wiped out during the last upgrade. None of the available color profiles seem to stink quite enough. Am I overlooking a renamed profile? Is there somewhere I could get a 'VGA Display' profile to install on my computer?

• How to copy a windows 7 user profile when changing domains

  - by Kris

  I need to connect my machine to a new domain soon. When I do so a new user profile will be created and I would like to copy all the settings/data from the old profile to the new one. This is a local profile only (no roaming). Running Windows 7 Enterprise 64 bit. I found this previous question on the same topic, it however only seems to address Windows XP and the solutions do not seem to apply to Win7.

• Default user profile getting filled with temp ie files

  - by Christoffer

  I have several Windows Server 2003 Terminal servers to service our domain users. Sometimes the Default User profile (C:\Documents and Settings\Default User) gets filled with tempoary internet files, so when a new user logs in, he gets a 1GB profile (instead of 20MB) that fills up the server fast. Why is it the default user profile gets filled up with files like that, by who and how do i prevent this?

• Check connection and reconnect wifi

  - by Ruud

  I'm building a wireless photoframe. The one thing I haven't been able to figure out is how to get my wifi connection back up using a recommended method. Right now I edited /etc/network/interfaces so wlan0 is started at boot: auto wlan0 iface wlan0 inet dhcp wireless-essid ourssid This method works fine for booting. But I found that if I do not check the connection for a long time (could be a week) it might be down. So I should reconnect. What I do now to verify the connection is working is downloading a file from the server that can't be cached (http://server.ext/ping.php?randomize=123456) If I fail to retrieve the file I assume that the connection is no longer working and I run a shell script like #!/bin/bash ifconfig wlan0 up iwconfig wlan0 essid "ourssid" dhclient wlan0 And the connection comes back. But I can't find anything if this is in any way a good method. Can this be improved upon, or is this already right?

• How can I install a specific older version of Firefox and keep it from automatically updating?

  - by Matt V.

  I wrote a bash script to configure a suite of tools for continuous integration on top of Ubuntu 10.04.2. The script recently stopped working and I tracked the problem down to the newer version of Firefox that was just released. The image of Ubuntu that I'm starting with already has Firefox installed, but I need a version in between what it comes with and the latest. Here's the code I was using: sudo add-apt-repository ppa:mozillateam/firefox-stable sudo apt-get update echo "y" | sudo apt-get install firefox How can I instead install Firefox 7.0.1 and keep it from automatically upgrading to the latest version? If I can, I'd like to avoid installing Firefox manually, so I can more easily use apt-get later, once the issue I'm running into gets resolved.
