• WIN7 and Ubuntu lost after Installing ubuntu 12.04 and win7 dual system ,I have no OS on my laptop now

  - by abos

  Here is the procedure: In the morning I installed ubuntu using a USB directly without config any thing to my win7 system. After install complete, ubuntu installation software tell me to reboot.And everything is just find. While rebooting, there is NO UBUNTU system for me to select,and my laptop go straight to log in using WIN7. NO ubuntu shows on WIN7's configuration(Default System). Log in ubuntu using usb(try ubuntu without installation), I can find ubuntu's filesystem was already there. Formatting the disk on WIN7's disk management, rearranging them to other disk.Still having no trouble with WIN7. In the afternoon try a few times of installation and uninstallation of ubuntu. still shows no sign of selecting ubuntu system. In the evening another trial while installing ubuntu with the third option of: installing ubuntu alongside with INW7, erase win7 and install ubuntu. somethingelse --- my check failed with configuartion for what comes out with the 'something else' option,reboot. And I have no system now with some cmd tips say: Reboot and Select proper Boot Device or Insert Boot Media in selected Boot device and press a key. Files those on win7's orginal file system and Ubuntu filesystem can still be found when I 'try ubuntu without installation'. 5.But I just got no OS when I reboot my laptop normally.

• One vs. many domain user accounts in a server farm

  - by mjustin

  We are in a migration process of a group of related computers (Intranet servers, SQL, application servers of one application) to a new domain. In the past we used one domain user account for every computer (web1, web2, appserver1, appserver2, sql1, sqlbackup ...) to access central Windows resources like network shares. Every computer also has a local user account with the same name. I am not sure if this is necessary, or if it would be easier to configure and maintain to use one domain user account. Are there key advantages / disadvantages of having one single user account vs. dedicated accounts per computer for this group of background servers? If I am not wrong, one advantage besides easier administration of the user account could be that moving installed applications and services around between the computers does not require a check of the access rights anymore. (Except where IP addresses or ports are used)

• Inserting static current time in Excel

  - by Mike Cole

  I have a time log spreadsheet. I have a new sheet for each day. In each sheet, I have a transactional record of how my time was spent. When I start or end a task, I usually type in the time ("11:00 AM" for example). Is there a shortcut to inserting the current time into a field? I'm sure it can be done with a macro, but I'm not very knowledgeable about macros. I'd like to simply highlight a field and hit some sort of shortcut key to insert a static value of the current time. Thanks for any help!

• some keyboard keys not working properly

  - by surfmadpig

  I'm using windows 7. All of a sudden, a couple of hours ago, this happened: My keyboard number keys [above the letters] stopped working properly, both as numbers and as symbols. Only 5 and 6 are functional. Also, I've noticed that the End key isn't working either, and perhaps a couple more from that group. I'm pretty sure it has something to do with those evil Sticky Keys/Filter Keys/ whatever those ease of access things are, BUT I've turned off all the ease of access keyboard options and nothing has changed. Is it possible that something is still turned on while I unchecked it? Are the on/off checkboxes to control WHEN it happens or IF it happens? I also tried rebooting and uninstalling/reinstalling keyboard from device manager, to no avail. It's certainly a software issue and not a hardware issue, as I've tried another keyboard and the problem persists. And, predictably enough, it's annoying. Any ideas?

• Mouse works fine but keyboard (not wireless) not responding to anything

  - by Christine Boeke

  I read previous questions like mine and looked to see if keys were depressed and checked to make sure the mouse key was off in the system preferences. The mouse works just fine but the keyboard seems to be dead. I plugged in another keyboard and it responded identically. Is it something in the Desktop itself? Could I need a technician? I have searched for answers on line and had no success. Thanks!

• How To Cancel Pending Windows 7 Updates

  - by Itai

  How To Cancel Pending Windows 7 Updates? The key is pending. The shutdown button has the windows update symbol meaning that there are updates that were selected to be installed which were download and will be installed upon shutdown. The only thing is that my machine will no longer boot if I let it install those updates! They are incompatible with a driver needed in the system and I did not found out until too late. The system admin used a recovery disk to get back to the previous restore point, only the updates are now pending, so I need to cancel those before the machine shutdowns next.

• Enable 8th bit as Meta in zsh without a warning

  - by Bostonvaulter

  In my quest to configure my shell to work exactly how I want it with respect to the alt/meta key I am having some trouble. Recently I added "bindkey -m" to my .zshrc and now whenever I start a zsh shell (ie open a terminal window) I get this error "warning: `bindkey -m' disables multibyte support". Now since I don't care much about multibyte support atm, is there a way I can disable just this warning? Even better would be a way to use 8th-bit meta as well as multibyte. Also note that this happens on a clean zsh install on 4.3.9 and 4.3.10 My reasoning for wanting bindkey -m vim: alt mappings (my own personal commands/mappings) zsh: alt mappings (such as Alt-. to recall the last argument of the previous command) emacs: alt mappings (lots of built-ins) So, is there any way to disable this warning or otherwise accomplish what I'm trying to do?

• Eliminate default SSL certificate

  - by microchasm

  I'm setting up a server for local access. I created a CA and have SSL certs signed and working on other domains. The problem is I'm trying to create a cert for a domain name that is the same as the host name? I copied the steps to make the cert for the other domain, but when I create and sign this cert, and modify httpd.conf with the path to the cert and key, the localhost.localdomain cert seems to be taking precedence. In other words, when I view the cert in firefox, it is the localhost.localdomain cert instead of the one I just created. I looked at ssl.conf, and tried to change the default path to the one issued, and I tried to comment out the VirtualHost, but neither worked. How can I override the servers default certificate with the one I issued and signed? Thanks.

• Ubuntu Connect Button Disabled, cannot connect

  - by CSharperWithJava

  I'm trying to connect to my school network from Ubuntu 12. The network is WPA encrypted and I can connect just fine if the network manager establishes a connection automatically. However, when I get disconnected and try to reconnect a username and password prompt pops up. The credentials are already stored and are autofilled in correctly, but the Connect button is disabled so I can't actually connect to the network. What can I do? The only guess I've found so far is the password is too short and Ubuntu is expecting a full WPA key. I don't administer the school network though so I certainly can't change that.

• Select firefox search result

  - by Nicolas C.

  I am working on a daily basis on a web application with very large menus. Also doing lots of other Excel manipulations, copy and pasting, etc., I am quite fond of keyboard shortcuts as much faster than using the mouse to point, double-click and then going back to my keyboard etc. Hence, my question is quite simple, does anyone know if there is any shortcut under Firefox which would let me actually select (and not highlight) in my web page the search result so that I can for instance do the following manipulation sequence? [Ctrl]+[F] type the search string, for instance 'regional_unit' the missing shortcut to actually select in my page the string which is currently highlighted thanks to the search feature of FF [Space] or [Enter] key to activate the web element which in my case would systematically correspond to a link or button, etc. May be there would be an addon replacing the default search feature, I don't know... I tried to look over the internet but with the words I am using for this investigation, I do not get relevant search results under Google :(. Thanks a lot

• using git on DOS command line asks for password - but not when using TortoiseGit or gitBash

  - by Sandy

  I would like to use the DOS command line to enter the command: git clone "git_path.git" myDir It asks me to enter a password which I would like to avoid. I usually use TortoiseGit to do all git related operations. I would like to setup cruisecontrol using ant with a custom git task. Therefore I need to perform git clone on the command line in Windows 7. But it only works using git bash and not DOS. According to other forum entries, I tried to convert the key with puttyGen and put the file id_rsa in c:/Users/myName/.ssh I also added an authorized_keys file but it still asks for a password. Any ideas? Thanks

• What is windows 8 core?

  - by Journeyman Geek

  I've found some references, when looking for information on WAIK installs of windows 8 of a varient called windows 8 core, that can be installed off the professional edition disk. There's also a mention of it on winsupersite that says The cheapest, called MSDN Operating Systems, costs $699 a year ($499 renewal), and of course includes Windows 8 (Core), Windows 8 Pro, and Windows 8 Enterprise. You get five licenses each for Windows 8 Core and Pro, and one Multiple Activation Key (MAK) for Windows 8 Enterprise. What is windows 8 core? Is it the new 'home' edition or something else? What differentiates it from the pro and enterprise editions?

• Nagios remote monitoring: NRPE Vs. SSH

  - by sam

  We use Nagios to monitor quite a few (~130) servers. We monitor CPU, Disk, RAM and a few other things on each server. I've always used SSH to run the remote commands, purely because it requires little to no additional config on the remote server, just install nagios-plugins, create the nagios user and add the SSH key, all of which I've automated into a shell script. I've never actually considered the performance implications of using SSH over NRPE. I'm not too bothered about the load hit on the Nagios server (It's probably over-speced for what it does, it's never been over 10% CPU), but we run each remote check every 30 seconds and each server has 5 different checks performed. I assume SSH requires more resources for each check but is there a huge difference? (I.E. enough of a difference to warrant the switch to NRPE). If it's any help, we monitor a mix of physical servers (Normally with 8, 12 or 16 physical cores) and Amazon EC2 medium/large instances.

• What software is available to keep track of hundreds of servers?

  - by djangofan

  What good software is available (free or not free) to help me keep track of information relating to hundreds of servers, their relationships to each other (parent/child, category, type), and information on connecting to them, as well as possibly showing a picture or grid of some kind that allows me to report these relationships and key information to my supervisor. I am trying to avoid the "spreadsheet solution" or "visio solution" because I want to share this information and make changes with other persons in my server team. In other words, the solution I am looking for is a cross between a spreadsheet solution and a visio solution, providing both graphing and configuration information WITHOUT monitoring, and in a consistent format.

• Ubuntu 11.10 loads from live usb fine, but boots to black screen from harddrive. Why?

  - by Estel

  A few days ago I had a hard drive failure, which was running Windows XP (32-bit) just fine. The second hard drive in my computer held a few unimportant files, so I formatted it in the Ubuntu setup and installed 11.10 without a hitch. I had been using it for about a week, but decided to install Windows 7 (64-bit) in order to utilize Networking with my home server (running Windows Server 2000). My system is 64-bit based, and thus I had no problems installing other than a basic RAM error that required me to remove my RAM down to a single stick. I played with the settings in Windows 7 for around an hour before I shut down. After reinstalling the RAM, Windows 7 would not boot. In this, I then assumed that something about my system was rejecting Win7 and I reinstalled Ubuntu. However, now Ubuntu (11.10) boots into black screen, and I've already attempted activating the grub menu with the shift key, and following steps listed here: https://wiki.ubuntu.com/X/Troubleshooting/BlankScreen but nothing seems to work. I've reinstalled twice now, with the same result each time. Now, the very odd part about this whole scenario is that the USB I installed from has no problems booting as a live USB. This puzzles me greatly, because the hard drive boots straight to black screen and the live USB loads normally. At this point, my only theory is that the boot sector of the hard disk was somehow corrupted with Win7, and that Ubuntu was unable to completely write through. I used Darik's Boot n Nuke to wipe the drive, but was met with an error, this also puzzles me because the hard disk has no promblems reading or writing. Any suggestions/comments are appreciated. If you have a theory, I will be more than happy to oblige. Additional information: Intel Core2 Duo e6400 2.13GHz nVidia GeForce 7-series (7900 GS) 4 GB DDR2 333MHz (2x 2GB) Dell XPS 410 BIOS Revision 2.5.3

• Notification area balloon tip pop sound in Windows 7

  - by Worm Regards

  When I was using Windows XP, there was a distinct sound when an application showed a balloon tip in the notification area (aka system tray). Unfortunately, I didn't look any deeper into it. Now Windows 7 has this behavior disabled by default and I do not know how to configure it. Discovered the name of sound file used to accompany tray balloon tips in Windows XP Windows XP Balloon.wav More clues: interesting registry key is HKEY_USERS\XP Registry Hive\AppEvents\Schemes\Apps\.Default\SystemNotification\.Default Default value is %SystemRoot%\media\Windows XP Balloon.wav So, the System Notification event label appears to be correct, but tray balloons are silenced elsewhere.

• Postfix configuration w.r.t. port 25

  - by Monkey Boson

  After a considerable amount of research, I have configured my postfix server to use dovecot to accept SMTPS connections over port 465 and everything works swimmingly. Unfortunately, I forgot that, unless I listen to port 25, I'm not going to receive any e-mail from the net. I'm hoping somebody knows off the top of their head how to open up port 25 on Postfix for anonymous users, but disallow relaying and any other bad things on that port. And to leave the port 465 the way it is. As to my current configuration, I changed the master.cf file: smtps inet n - n - - smtpd and the main.cf file: # Use our SSL certificates smtpd_tls_cert_file = .....cer smtpd_tls_key_file = .....key smtpd_tls_security_level = may # Use Dovecot for SASL authentication smtpd_sasl_auth_enable = yes smtpd_sasl_security_options = noanonymous smtpd_sasl_type = dovecot smtpd_sasl_path = private/auth broken_sasl_auth_clients = yes smtpd_recipient_restrictions = permit_sasl_authenticated, reject_unauth_destination Any help is appreciated!

• Python Web Applications: What is the way and the method to handle Registrations, Login-Logouts and Cookies? [on hold]

  - by Phil

  I am working on a simple Python web application for learning purposes. I have chosen a very minimalistic and simple framework. I have done a significant amount of research but I couldn't find a source clearly explaining what I need, which is as follows: I would like to learn more about: User registration User Log-ins User Log-outs User auto-logins I have successfully handled items 1 and 3 due to their simple nature. However, I am confused with item 2 (log-ins) and item 4 (auto-logins). When a user enters username and password, and after hashing with salts and matching it in the DB; What information should I store in the cookies in order to keep the user logged in during the session? Do I keep username+password but encrypt them? Both or just password? Do I keep username and a generated key matching their password? If I want the user to be able to auto-login (when they leave and come back to the web page), what information then is kept in the cookies? I don't want to use modules or libraries that handle these things automatically. I want to learn basics and why something is the way it is. I would also like to point out that I do not mind reading anything you might offer on the topic that explains hows and whys. Possibly with algorithm diagrams to show the process. Some information: I know about setting headers, cookies, encryption (up to some level, obviously not an expert!), request objects, SQLAlchemy etc. I don't want any data kept in a single web application server's store. I want multiple app-servers to be handle a user, and whatever needs to be kept on the server to be done with a Postgres/MySQL via SQLAlchemy (I think, this is called stateless?) Thank you.

• Dead-simple USB-based Windows partition cloner?

  - by OverTheRainbow

  Clonezilla is a fine open-source tool, but it requires going through several screens. Since I need to save/restore the same Windows partition, I was wondering if someone knew of a tool (open-source or not) that is easier to use and boots off a USB keydrive. Ideally, it'll save the two commands to save/restore a partition, so I just need to boot the host from the USB key, choose the command, and it'll take care of business. Are there solutions that look like this? Thank you. Edit: Here's one among other articles that shows how to tell CZ to run a script to avoid the multiple screens.

• Opportunities in Cloud Computing

  - by Paul Sorensen

  A recent article from CIO Journal indicates that there is an extreme labor shortage (in certain technology areas) that is is leading to upward pressure on wages for IT Workers. This represents a great opportunity for those with certain skill-sets, among which include Java (Oracle certification is mentioned specifically). The article points out that a key driver of the labor shortage is the expansion of cloud computing. Cloud computing is set up to make life extremely simple for end-users, but the model pushes the complexity to back-end systems which are sophisticated, enterprise-level computing stacks (Oracle has an extensive set of cloud computing solutions). These complex systems require very highly-skilled IT professionals (the best-of-the-best) to successfully develop, implement, administer and maintain them. What this mean for you is that there is opportunity for those who have the appropriate skills at the appropriate levels. If you want to be a part of this opportunity you should do a self-assessment of your own skill-sets and experience. Based upon your results you can decide where it would be most appropriate to spend your time and resources for the highest return on your investment. By expanding and sharpening your skills and by gaining greater experience you will be better prepared to take advantage of career opportunities (like this) that come along periodically. As you evaluate your needs remember that Oracle University has a tremendous selection of high-quality eduction offerings (including training and certification) that can you help move your career forward. Thanks and best of luck!

• Skip CodedUI Tests, use Selenium for Web Automation

  - by Aligned

  Originally posted on: http://geekswithblogs.net/Aligned/archive/2013/10/31/skip-codedui-tests-use-selenium-for-web-automation.aspxI recently joined a team that was using Agile Methodologies to create a new product. They have a working beta product after 10 or so 2 week sprints and already had UI’s that had changed several times as they went through iterations of their UI. As a result, the QA team was falling behind with automated tests and I was tasked to help them catch up and expand their tests. The project is a website. I heard many complaints about how hard it is to work with CodedUI (writing our own code, not relying on the recorder as we wanted re-usable and more maintainable code) then it took me 4+ hours to fix one issue. It was hard to traverse the key and debugging the objects with breakpoints… I said out loud “there has to be a better way or a framework the uses jQuery to run through the tests.” Plus it seemed really slow (wait… finding the object … wait… start putting in text…). Plus some tests would randomly fail on the test agents (using the test settings and an automated build, they are run on VMs using Microsoft test agents). Enough complaining. Selenium to the rescue (mostly). The lead QA guy decided to try it out and we haven’t turned back. We are now running tests in Chrome and Firefox and they run a lot faster. We had IE running to, but some of the tests were running fine locally, but hanging on the test agents. I’ll add some hints and lessons learned in a later post.
