• Every command fails with "command not found" after changing .bash_profile?

  - by Blankman

  I was updating my .bash_profile, and unfortunetly I made a few updates and now I am getting: env: bash: No such file or directory env: bash: No such file or directory env: bash: No such file or directory env: bash: No such file or directory env: bash: No such file or directory -bash: tar: command not found -bash: grep: command not found -bash: cat: command not found -bash: find: command not found -bash: dirname: command not found -bash: /preexec.sh.lib: No such file or directory -bash: preexec_install: command not found -bash: sed: command not found -bash: git: command not found My bash_profile actually pulls in other .sh files (sources them) so I am not exactly sure which modification may have caused this. Now if I even try and to a list of files, I get: >ls -bash: ls: command not found -bash: sed: command not found -bash: git: command not found Any tips on how to trace the source of the error, and how to be able to use the terminal for basic things like listing files etc?

• Google Chrome proxy settings?

  - by becko

  When I try to set Google Chrome's proxy settings (on chrome://linux-proxy-config/), I get the following message: When running Google Chrome under a supported desktop environment, the system proxy settings will be used. However, either your system is not supported or there was a problem launching your system configuration. But you can still configure via the command line. Please see man google-chrome-stable for more information on flags and environment variables. I need to set proxy settings to use Chrome, but I don't want to be setting them in the command line every time I use Chrome. Is there a way to set these settings permanently? Also, is there an option in Chrome so that it doesn't use proxy for specific domains (analogous to the No proxy for setting in Firefox)?

• Cannot Install/Start MySQL Server

  - by Peezy Bro

  Okay, I decided to migrate from MySQL Server 5.5.37 to Percona Server 5.6. I ended up removing MySQL Server by the following: sudo apt-get --purge remove mysql-server mysql-server-5.5 mysql-server-core-5.5 mysql-client mysql-client-core-5.5 mysql-common sudo apt-get autoremove sudo apt-get autoclean rm -rf /var/lib/mysql rm -rf /etc/mysql Now here is my problem, when I try to install MySQL Server 5.6 it goes through its process and when it asks me for a password, it comes up with Cannot set MySQL "root" password.

• How do you successfully hire out a few programmers to make it cost effective?

  - by Chris

  Many of us know this situation well: we're a one-man (woman) development team, we need some extra help to keep up with all the tasks, the budget is small and we decide to get some help. But hiring someone is difficult. Either the person is inexperienced and I end up becoming their full-time teacher in the hopes they will produce work they way I want, or the person is skilled but for whatever reason doesn't hand over code within budget that I can just plug in and use without reworking it myself. Any thoughts/ideas?

• On Life and TechEd&hellip;

  - by MOSSLover

  I haven’t been writing here I know.  I am very sorry, but I am just too busy trying to make my personal life just as good as my SharePoint life.  So I was at TechEd again helping with the hands on labs, but I had a very long couple of weeks.  I will have a long week again.  I started out going to my friend, Randy Walker’s, wedding and I ended up at my grandmother’s condo in Fort Lauderdale.  It was a very trying week.  I had to drive 5 1/2 hours to the wedding from St. Louis and back.  So Randy is an awesome person.  He is a great guy and he was the first person ever to nominate me for MVP.  I knew it probably wasn’t going anywhere, but it was the thought that count.  I met Randy in 2008 at Tulsa Techfest.  We had fun jamming out to Rockband.  I knew he was good people back then.  He has let me vent and I have let him vent over countless personal problems.  He has always been a great friend.  So it was a no brainer when I decided to go to his wedding no matter how much driving or stress or lack of sleep it was worth it.  I am incredibly happy for him to finally find a diamond amongst a lot of coal.  To take part in his celebration was so awesome.  I thank him again for letting me participate in this ceremony. Now after Randy’s wedding I drove 5 1/2 hours landed in St. Louis, fed a cat an asthma pill hidden in wet cat food, and slept for 4 hours.  I immediately saw my best friend who dropped me off at the airport and proceeded to TechEd.  I slept 1 hour on each flight, then ended up working a 3 hour shift at TechEd.  The rest of the week was a haze of connecting with people and sleeping very little.  I got to see my friend Tasha and her husband Casey plus a billion other people.  It was a great week and then I got a call from my grandmother.  It turns out her husband was admitted to the hospital. My grandparents on my dad's side have been divorced since the 60s, which means I never got to see them together.  I always felt like they never cliqued.  When I was a kid we would always spend half our time in Chicago at grandma’s and half our time at grandpa’s houses.  We would hang out with my grandpa’s wife Bobbi and my grandma’s husband Leo.  My cousin’s always called Leo by Pappa and my brother and I would use Leo.  My cousins lived in Chicago up until my cousin Gavi was born then they moved to Philadelphia.  I remember complaining to my dad that we never visited anywhere cool just Chicago and Kansas City.  I also remember Leo teaching me and my brother, Sam, how to climb a tree and play tennis on the back of the apartment wall.  My grandfather’s was kind of stuffy and boring, but we always enjoyed my grandmother’s.  She had games and Disney Movies and toys.  Leo always made it a ton of fun to visit.  I’m not sure a lot of people knew this fact, but when I was 16 years old I saw my grandfather on my mother’s side slowly die of congestive heart failure in a nursing home.  When I was 18 I saw my grandmother on my mother’s side slowly die of an infection over a 30 day period.  I hate hospitals and I hate nursing homes, but sometimes you have to suck in your gut and be strong.  I tried to do that this weekend and I hope I did an ok job.  I really hope things get better, but if they don’t I really appreciate everything he has given me in life.  I am a terrible tennis player and I haven’t climbed a tree in ages, but they both encouraged me when encouragement from my parents was lacking.  It was Father’s Day today and I have to at least pay tribute to Leo Morris, because he has been a good person to me all my life.  Technorati Tags: TechEd,Grandparents,Father's Day

• Why do I recieve multiple warnings of "No running instance of xfce4-panel was found" when logging into Xubuntu?

  - by Fredrik

  I'm running Xubuntu 11.04, the bootup-time is quite fast but when I log in it takes close to a minute before the desktop is displayed, meanwhile I see no activity on the hard drive.

• Why is this rkhunter script sending empty emails?

  - by Oddthinking

  I have started running rkhunter (a security monitoring tool) and I have finally managed to clear all of its warnings. Now, a cron job runs every day to monitor my machine. Rather than send me an email of warnings, it sends me an email with no body - which I don't really want. Looking at the (unedited, straight out of the box) /etc/cron.daily/rkhunter script, it contains this snippet of shell code: if [ -s "$OUTFILE" ]; then ( echo "Subject: [rkhunter] $(hostname -f) - Daily report" echo "To: $REPORT_EMAIL" echo "" cat $OUTFILE ) | /usr/sbin/sendmail $REPORT_EMAIL fi The -s clause should prevent empty emails from being sent, right? Does anyone have an explanation why this would still send empty emails?

I thought this tutorial here would have solved this problem (i am simply trying to set up local mail reading with mutt, using gmail) but I cannot see the instructed things with telnet: "250-STARTTLS 250-AUTH PLAIN LOGIN" so that is why it is not working. $cat .muttrc set imap_user = "[email protected]" set imap_pass = "pass" #set smtp_url = "smtp://[email protected]:465/" set smtp_url = "smtp://[email protected]:587/" set smtp_pass = "pass" set from = "[email protected]" set realname = "name" set folder = "imaps://imap.gmail.com:993" set spoolfile = "+INBOX" set postponed="+[Gmail]/Drafts" set move = no

• Inspiring problems to show off the importance of regular expressions?

  - by ragu.pattabi

  I am planning to give a presentation/demonstration on regular expressions at work to encourage young developers to add this powerful and important tool in their toolbox. Just teaching syntax doesn't cut it. I often see people say nice. After the presentation, they get on with their programming lives without ever thinking of using it mostly. I am raking my grey matter to come up with some solid examples, not just problems that matches 'cat' and 'cut'. I missed to note down the occasions of my regex enlightenments to use here. :^( Do you have some inspiring problems to share that could be solved with regex?

• How one does qualify as a Web UI Developer?

  - by Duralumin

  I have about 20 years of experience with programming, most of that on the job, and right now, I define myself as a Web Developer, because I think about half my expertise lies in the all too extended "web" field, both server side and client side, and because in the last years I'm mostly doing web development. I know my javascript, jQuery, jQueryUI, HTML4-5, css2-3 and some frameworks like backbone.js and angularJS Since university I've always been interested in Man-Machine Interaction, UI and UX. Recently, I saw the label "Web UI Developer" tossed around, and I thought that would be something I would like to qualify for. And I'd really like to qualify with confidence. I didn't find any certificate or similar, and I don't think there are any. Is the only way to qualify as a Web UI Developer having a job as one? What are the skills I need to have, and the resources I can use to acquire them?

• On VirtualBox Guest OS “Could not initialize GLX"

  - by trivelt

  I have a remote build-machine with Jenkins and I'm trying to run GUI application. In Jenkins I installed Xvnc plugin, which uses TightVNC Server, but each build has failed. Earlier, there was a problem with loading driver swrast (by libGL), currently in the log there is this line: [Error] Could not initialize GLX Remote desktop is Ubuntu 14.04 running over VirtualBox, so I installed VBoxAddons but it didn't resolve the problem. Below I'm putting some logs, maybe helpful for you. $ cat /var/log/Xorg.0.log | grep GL [ 20.545] (==) AIGLX enabled [ 20.545] Loading extension GLX [ 20.913] (EE) AIGLX error: vboxvideo does not export required DRI extension [ 20.914] (EE) AIGLX: reverting to software rendering [ 21.615] (II) AIGLX: Loaded and initialized swrast [ 21.615] (II) GLX: Initialized DRISWRAST GL provider for screen 0 $ lsmod | grep box vboxsf 43786 0 vboxpci 23194 0 vboxnetadp 25670 0 vboxnetflt 27613 0 vboxdrv 339502 3 vboxnetadp,vboxnetflt,vboxpci vboxvideo 12658 0 vboxguest 248441 3 vboxsf drm 302817 1 vboxvideo $ lspci | grep VGA 00:02.0 VGA compatible controller: InnoTek Systemberatung GmbH VirtualBox Graphics Adapter Any ideas what should I do?

• Wozu eigentlich Oracle Linux?

  - by Manuel Hossfeld

  Zur Abwechslung gibt es heute mal einen kürzeren Artikel, und zwar zum Thema "Oracle Linux". Der eine oder andere mag sich vielleicht schon mal gefragt haben, warum man sich mit diesem "Red Hat Klon" überhaupt auseinandersetzen sollte. Gibt es neben dem "Support aus einer Hand"-Argument noch andere Gründe, warum sich Kunden dafür entscheiden, Oracle Linux einzusetzen? Diese und ähnliche Fragen hat eine kürzlich erschienene IDC-Studie beleuchtet. Sie trägt den Titel: "Oracle Linux Takes Its Place in the Operating Systems Market". Interessant ist vor allem ein konkretes Kundenbeispiel am Ende der Studie. Da es thematisch gerade passt sei zum Schluss noch ein kleiner Hinweis in eigener Sache erlaubt:Viele der in dem Paper erwähnten Aspekte und Features (wie z.B. KSplice für Reboot-freie Kernel-Updates) werden auch auf der diesjährigen DOAG-Konferenz in Nürnberg behandelt. Mein Kollege Lenz Grimmer und ich halten dort einen Vortrag mit dem Titel: "Oracle Linux - Best Practices und Nutzen (nicht nur) für die Oracle DB"20.11.2012, 15:00 - 15:45 Uhr, Raum Kiew
