  • Dell Optiplex 980 vs. Dell Studio XPS 9000?

    - by Dave
    My company is allowing me to upgrade to either the XPS 9000 or the Optiplex 980. I haven't bought an Optiplex in over a decade, and the only thing I can remember is that the Optiplex is really meant for corporate IT environments, and we're not even close being large enough to have IT issues. I think the components might be of higher quality as well, like the motherboard and power supply. The XPS 9000 is about $150 cheaper than the Optiplex, but the Optiplex has 4GB more RAM, a 2nd video card, and an extra year of service. Seems like the Optiplex is a better deal overall, but since I haven't ever used one, I wanted to see what everyone else here thought.

  • IE8 Developer Tools won't open

    - by Dave
    Just installed IE8 on WinXP. Trying to use the Dev Tools but, clicking on the menu item or hitting F12 doesn't do anything. I can see the option in the tools menu, just can't use it. I've checked to make sure it wasn't opening minimized or off screen and I've checked the registry settings used to disable them. Those registry keys don't even exists. Suggestions? I was going to reinstall, but, thought I'd check here first.

  • Dropped hard drive won't mount

    - by Dave DeLong
    I have a 2 TB HFS+-formatted external hard drive that got dropped a couple of days ago while transferring files onto a Macbook Pro. Now the drive's partitions won't mount. Disk Utility can see the drive, but doesn't recognize that it has any partitions. I've tried using Data Rescue 2 to recover files off of it, but it couldn't find anything. In addition, our local computer repair shop said they couldn't find anything on there either. I know that I could ship the drive off to someone like DriveSavers, but I was hoping for a cheaper option (since they start at about $500 for the attempt). Is there something else I could try on my own? Would TestDisk be able to help with something like this?

  • Migrate from MySQL to PostgreSQL on Linux (Kubuntu)

    - by Dave Jarvis
    Storyline Trying to migrate a database from MySQL to PostgreSQL. All the documentation I have read covers, in great detail, how to migrate the structure. I have found very little documentation on migrating the data. The schema has 13 tables (which have been migrated successfully) and 9 GB of data. MySQL version: 5.1.x PostgreSQL version: 8.4.x I want to use the R programming language to analyze the data using SQL select statements; PostgreSQL has PL/R, but MySQL has nothing (as far as I can tell). A long time ago in a galaxy far, far away... Create the database location (/var has insufficient space; also dislike having the PostgreSQL version number everywhere -- upgrading would break scripts!): sudo mkdir -p /home/postgres/main sudo cp -Rp /var/lib/postgresql/8.4/main /home/postgres sudo chown -R postgres.postgres /home/postgres sudo chmod -R 700 /home/postgres sudo usermod -d /home/postgres/ postgres All good to here. Next, restart the server and configure the database using these installation instructions: sudo apt-get install postgresql pgadmin3 sudo /etc/init.d/postgresql-8.4 stop sudo vi /etc/postgresql/8.4/main/postgresql.conf Change data_directory to /home/postgres/main sudo /etc/init.d/postgresql-8.4 start sudo -u postgres psql postgres \password postgres sudo -u postgres createdb climate pgadmin3 Use pgadmin3 to configure the database and create a schema. A New Hope The episode began in a remote shell known as bash, with both databases running, and the installation of a command with a most unusual logo: SQL Fairy. perl Makefile.PL sudo make install sudo apt-get install perl-doc (strangely, it is not called perldoc) perldoc SQL::Translator::Manual Extract a PostgreSQL-friendly DDL and all the MySQL data: sqlt -f DBI --dsn dbi:mysql:climate --db-user user --db-password password -t PostgreSQL > climate-pg-ddl.sql mysqldump --skip-add-locks --complete-insert --no-create-db --no-create-info --quick --result-file="climate-my.sql" --databases climate --skip-comments -u root -p The Database Strikes Back Recreate the structure in PostgreSQL as follows: pgadmin3 (switch to it) Click the Execute arbitrary SQL queries icon Open climate-pg-ddl.sql Search for TABLE " replace with TABLE climate." (insert the schema name climate) Search for on " replace with on climate." (insert the schema name climate) Press F5 to execute This results in: Query returned successfully with no result in 122 ms. Replies of the Jedi At this point I am stumped. Where do I go from here (what are the steps) to convert climate-my.sql to climate-pg.sql so that they can be executed against PostgreSQL? How to I make sure the indexes are copied over correctly (to maintain referential integrity; I don't have constraints at the moment to ease the transition)? How do I ensure that adding new rows in PostgreSQL will start enumerating from the index of the last row inserted (and not conflict with an existing primary key from the sequence)? Resources A fair bit of information was needed to get this far: https://help.ubuntu.com/community/PostgreSQL http://articles.sitepoint.com/article/site-mysql-postgresql-1 http://wiki.postgresql.org/wiki/Converting_from_other_Databases_to_PostgreSQL#MySQL http://pgfoundry.org/frs/shownotes.php?release_id=810 http://sqlfairy.sourceforge.net/ Thank you!

  • Security as a Service (SecaaS) for Amazon EC2

    - by Dave
    I'm looking for a security as a service (SecaaS) provider or open source solution for Amazon EC2 instances, however I can't seem to find much on Google or elsewhere so was wondering if anyone knows where I could find this service? Ideally I'm looking for something that offers virtual firewalls, email and web security and virtual spam prevention. If anyone has any information on SecaaS i'd appreciate it, Thanks in advance

  • Setting up Mono/ASP.NET 4.0 on Apache2/Ubuntu: Virtual hosts?

    - by Dave
    I'm attempting to setup Mono/ASP.NET 4.0 on my Apache server (which is running on Ubuntu). Thus far, I've been following a few tutorials/scripts supplied here, and here. As of now: Apache 2.2 is installed (accessible via 'localhost') Mono 2.10.5 is installed However, I'm struggling to configure Apache correctly... apparently the Virtual Host setting isn't doing its job and invoking the mod_mono plugin, nor is it even pulling source from the proper directory. While the Virtual Host setting points to '\srv\www\localhost', it clearly is pulling content instead from 'var/www/', which I've found is the default DocumentRoot for virtual hosts. I can confirm: "/opt/mono-2.10/bin/mod-mono-server4" exists. Virtual hosts file is being read, since undoing the comment in the main httpd.conf changed the root directory from 'htdocs' to 'var/www/' The Mono installation is at least semi-capable of running ASP 4.0, as evidenced by running XSP, navigating to 0.0.0.0:8080/ and getting an ASP.NET style error page with "Mono ASP 4.0.x" at the bottom. Can anyone point out how to fix these configurations and get Mono linked up with Apache? Here are my configs and relevant information: /usr/local/apache2/conf/httpd.conf: # # This is the main Apache HTTP server configuration file. It contains the # configuration directives that give the server its instructions. # See <URL:http://httpd.apache.org/docs/2.2> for detailed information. # In particular, see # <URL:http://httpd.apache.org/docs/2.2/mod/directives.html> # for a discussion of each configuration directive. # # Do NOT simply read the instructions in here without understanding # what they do. They're here only as hints or reminders. If you are unsure # consult the online docs. You have been warned. # # Configuration and logfile names: If the filenames you specify for many # of the server's control files begin with "/" (or "drive:/" for Win32), the # server will use that explicit path. If the filenames do *not* begin # with "/", the value of ServerRoot is prepended -- so "logs/foo_log" # with ServerRoot set to "/usr/local/apache2" will be interpreted by the # server as "/usr/local/apache2/logs/foo_log". # # ServerRoot: The top of the directory tree under which the server's # configuration, error, and log files are kept. # # Do not add a slash at the end of the directory path. If you point # ServerRoot at a non-local disk, be sure to point the LockFile directive # at a local disk. If you wish to share the same ServerRoot for multiple # httpd daemons, you will need to change at least LockFile and PidFile. # ServerRoot "/usr/local/apache2" # # Listen: Allows you to bind Apache to specific IP addresses and/or # ports, instead of the default.

  • IIS 7.5 + Windows Server 2008 R2 + ASP.NET 4.0 HTTP 500 Error?

    - by Dave
    Hi, I'm having an issue I cannot track down and I have looked through the forums and not found anything that sheds any light. I have a fresh install of a Server 2008 R2 Web that I am trying to load an application I created and tested on a Windows 7 machine running IIS 7.5 using ASP.NET 4.0. Everything works fine on the dev machine. But when I used the Web Deployment tool to move it to the server, I now get a HTTP 500 error without a lot of information: Module AspNetInitClrHostFailureModule Notification BeginRequest Handler StaticFile Error Code 0x80070002 Requested URL http://192.168.1.83:80/ Physical Path C:\JustStreamIt Logon Method Not yet determined Logon User Not yet determined Failed Request Tracing Log Directory C:\inetpub\logs\FailedReqLogFiles And in my trace file I get: view trace Warning -SET_RESPONSE_ERROR_DESCRIPTION ErrorDescription An error message detailing the cause of this specific request failure can be found in the application event log of the web server.

  • Perfmon - Redirector current command 0 result

    - by Dave
    I'd like to monitor how many SMB connections there are at any given time for my 2008R2 file server, but when I add Redirector/Current Commands in perfmon, I get 0 results. This KB from Microsoft isn't exactly helpful either: http://support.microsoft.com/kb/2523382 It mearly confirms there is an issue, but doesn't provide a work around. How would I go about getting the current number of SMB connections? Thanks for your help in advance.

  • Stack overflow in xp cmd console

    - by Dave
    I am using an older program whose source code I cannot see. I am using the cmd.exe console in windows xp. The program ran with no problems on an xp machine last year, while a stack overflow code 2000 error was observed on a different xp machine (easy fix - use the machine that works). I tried running the program on the previously working machine lately, and now am getting the same error. No changes to the os were made and I did not change the service pack version. Any ideas on how to get around this stack overflow error so I can use the program? Dosbox will at least open the program, however it does not run to completion. Thanks!

  • Use icacls to make a directory read-only on Windows 7

    - by Dave G
    I'm attempting to test some filesystem exceptions in a Java based application. I need to find a way to create a directory that is located under %TMP% that is set to read-only. Essentially on UNIX/POSIX platforms, I can do a chmod -w and get this effect. Under Windows 7/NTFS this is of course a different story. I'm running into multiple issues on this. My user has "administrative" right (although this may not always be the case) and as such the directory is created with an ACL including: NT AUTHORITY\SYSTEM BUILTIN\Administrators <my current user> Is there a way using icacls to essentially get this directory into a state where it is read-only PERIOD, do my test, then restore the ACL for removal? EDIT With the information provided by @Ansgar Wiechers I was able to come up with a solution. I used the following: icacls dirname /deny %username%:(WD) In the page located here I found this in the remarks section: icacls preserves the canonical order of ACE entries as: * Explicit denials * Explicit grants * Inherited denials * Inherited grants By performing the above icalcs command, I was able to set the current user's ability to write or append files (WD) to the directory to deny. Then it was a question of returning it to a state post test: icacls dirname /reset /t /c Done

  • How do I get numbers before and after a colon within a cell in Calc?

    - by Dave M G
    I have some cells which contain times entered in by users, which are written in the following format: mm:ss. There are never any hours. The seconds always have leading zeroes. The minutes may or may not have leading zeros. Because I need to separate out the minutes and seconds for various operations, I need to be able to get at the numbers before and after the colon. How do I select the number before a colon in a cell, and how do I select the number after?

  • AVG 9 (Internet Security Business Edition) and IIS 6.0

    - by Dave Holland
    Are any of you using AVG 9 Internet Security Business Edition along with IIS 6.0 and if so have you experienced problems? We just went from 8.5 to 9.0... Luckily I tried on only one of the servers in the web farm first to run for a week to make sure it played well with my servers. A few hours after the install all web apps were giving a "connection refused" error. Neither iisrest or restarting world wide web publishing services resolves the issue, only rebooting the machine brings the webs back up. They are all ASP.Net sites by the way (v2.5). What's interesting is if I take the machine out of the load balancer, the machine runs fine and the webs are just fine for days... as soon as i put it back in the pool it's only a few hours before its sad. The only thing I can think of right now is that the Resident Shield may be causing an issue, any thoughts?

    - by dave.zap
    I am not able to get a remote connection established to MySQL. From my pc I am able to telnet to 3306 on the existing server, but when I try the same with the new server it hangs for few minutes then returns # mysql -utest3 -h [server ip] -p Enter password: ERROR 2003 (HY000): Can't connect to MySQL server on '[server ip]' (110) Here is some output from the server. # nmap -sT -O localhost -p 3306 ... PORT STATE SERVICE 3306/tcp closed mysql ... # netstat -anp | grep mysql tcp 0 0 [server ip]:3306 0.0.0.0:* LISTEN 6349/mysqld unix 2 [ ACC ] STREAM LISTENING 12286 6349/mysqld /DATA/mysql/mysql.sock # netstat -anp | grep 3306 tcp 0 0 [server ip]:3306 0.0.0.0:* LISTEN 6349/mysqld unix 3 [ ] STREAM CONNECTED 3306 1411/audispd # lsof -i TCP:3306 COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME mysqld 6349 mysql 10u IPv4 12285 0t0 TCP [domain]:mysql (LISTEN) I am running... OS CentOS release 5.8 (Final) mysql 5.5.28 (Remi) Note: Internal connections to mysql work fine. I have disabled IPtables, the box has no other firewall, it runs Apache on port 80 and ssh no problem. Had followed this tutorial - http://www.cyberciti.biz/tips/how-do-i-enable-remote-access-to-mysql-database-server.html I have bound the IP address in my.cnf user=mysql bind-address = [sever ip] port=3306 I even started over by deleting the mysql folder in my datastore and running mysql_install_db --datadir=/DATA/mysql --force Then recreated all the users as per the manual... http://dev.mysql.com/doc/refman/5.5/en/adding-users.html I have created one test user CREATE USER 'test'@'%' IDENTIFIED BY '[password]'; GRANT ALL PRIVILEGES ON *.* TO 'test'@'%' WITH GRANT OPTION; FLUSH PRIVILEGES; So all I can see is that the port is not really open. Where else might I look? thanks

  • Corporate Wiki Organization - Technical Documentation

    - by Dave Jarvis
    Corporations have documents describing various aspects of their technical systems, including: Custom Applications Custom Development Frameworks Third Party Applications Accounting Bug Tracking Network Management How To Guides User Manuals Web Browsers Software Tools Development IDEs Graphics GIMP xv Text Editing File Transfer ncFTP WinSCP Hardware Servers Web Database Exchange File Network Devices Printers Drawings If you had to use a Wiki to manage the documentation, what other items would you add to the list, and how would you organize it? (For example, would Software Tools make more sense under Third Party Applications?) A few constraints: The structure should not go beyond three levels deep. Avoid the word "and" in favour of two different categories. Keep the structure general: it should appy as broadly as possible. Target audience is primarily technical, but could be visible by anyone.

  • Unable to browse Server 2008R2 from XP clinets

    - by Dave M
    We have just deployed a Windows 2008R2 server in our Windows 2003 domain. XP clinets are unable to browse in "entire network" and find the new server. It can be accessed by entering \\servername and it can be pinged by name and IP address. Users access shares without issue. Netbios over TCP/IP is enabled. Computer browser is running on the Windows 2008R2 system. Turn on Network Discovery is enabled.

  • USB to LPT adapter?

    - by Dave
    I'm bummed out, pretty much all of our computers here lack parallel ports. I have an EETools ChipMax programming tool that has one of the old-school Centronics connectors on the back. I figured that someone must make a USB to LPT adapter. Sure enough, I found one from iogear, the GUC1284B that is a USB to Parallel Printer cable. Note the boldface on the Printer. It must connect to a printer -- it isn't some generic USB to parallel interface, unfortunately. Does anyone here know of an adapter that works for parallel devices that aren't printers? I'd hate to have to buy a USB version of the ChipMax when I don't need to use it very much.

  • Are there any tools for monitoring individual Apache virtual hosts in real-time?

    - by Dave Forgac
    I'm looking for a way to monitor and record Apache traffic, separated by virtual host. I am currently using Munin to capture this and other data for the entire server however I can't seem to find a way to do this by vhost. This link describes using a module called mod_watch which is apparently no longer in development: http://www.freshnet.org/wordpress/2007/03/08/monitoring-apaches-virtualhost-with-munin/ The file that is listed as being compatible with Apache 2.x is reported to have problems with missing vhosts an reporting data correctly. Does anyone know of a reliable way to determine real-time traffic per vhost? If I can find this it should be easy enough to write a new Munin plugin. Edit: What I'd really like to see is something similar to the Apache server-status scoreboard page with the number of connections / requests separated by virtual host. This would give me the ability to check which vhost may be experiencing a spike in traffic in real time and would also provide the data needed for a Munin module (or some alternative performance monitoring / analysis system.)

  • Does anyone own a compaq 610? Fan Issues.

    - by Dave
    Hi, I've just purchased 2 HP compaq 610s and both have the same problem, that the fan is constantly on and the base is fairly hot. HP assures me that this is unusual and that I should return them as DOA. Becasue both laptops have this issue, I think that it may be a design flaw rather than a one off problem. Can any 610 owners comment? Is their fan constantly on too?

  • nginx does not use variables set in /etc/environment on system reboot, but does when restarted from shell

    - by Dave Nolan
    I have a Rails app running on nginx/passenger. It restarts happily in a shell using sudo /etc/init.d/nginx stop|start|restart. But Passenger throws an error when the system is rebooted: "Missing the Rails #{version} gem". But GEM_HOME and GEM_PATH are both set in /etc/environment so surely they would be available to all processes during reboot? /etc/environment PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/bin/X11:/usr/games" GEM_HOME=/var/lib/gems/1.8 GEM_PATH=/var/lib/gems/1.8 /etc/init.d/nginx #! /bin/sh ### BEGIN INIT INFO # Provides: nginx # Required-Start: $all # Required-Stop: $all # Default-Start: 2 3 4 5 # Default-Stop: 0 1 6 # Short-Description: starts the nginx web server # Description: starts nginx using start-stop-daemon ### END INIT INFO PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin DAEMON=/opt/nginx/sbin/nginx NAME=nginx DESC=nginx test -x $DAEMON || exit 0 # Include nginx defaults if available if [ -f /etc/default/nginx ] ; then . /etc/default/nginx fi set -e case "$1" in start) echo -n "Starting $DESC: " start-stop-daemon --start --quiet --pidfile /var/log/nginx/$NAME.pid \ --exec $DAEMON -- $DAEMON_OPTS echo "$NAME." ;; stop) echo -n "Stopping $DESC: " start-stop-daemon --stop --quiet --pidfile /var/log/nginx/$NAME.pid \ --exec $DAEMON echo "$NAME." ;; restart|force-reload) echo -n "Restarting $DESC: " start-stop-daemon --stop --quiet --pidfile \ /var/log/nginx/$NAME.pid --exec $DAEMON sleep 1 start-stop-daemon --start --quiet --pidfile \ /var/log/nginx/$NAME.pid --exec $DAEMON -- $DAEMON_OPTS echo "$NAME." ;; reload) echo -n "Reloading $DESC configuration: " start-stop-daemon --stop --signal HUP --quiet --pidfile /var/log/nginx/$NAME.pid \ --exec $DAEMON echo "$NAME." ;; *) N=/etc/init.d/$NAME echo "Usage: $N {start|stop|restart|force-reload}" >&2 exit 1 ;; esac exit 0 $ opt/nginx/sbin/nginx -v nginx version: nginx/0.7.67 Ubuntu lucid

  • MS SQL Server slows down over time?

    - by Dave Holland
    Have any of you experienced the following, and have you found a solution: A large part of our website's back-end is MS SQL Server 2005. Every week or two weeks the site begins running slower - and I see queries taking longer and longer to complete in SQL. I have a query that I like to use: USE master select text,wait_time,blocking_session_id AS "Block", percent_complete, * from sys.dm_exec_requests CROSS APPLY sys.dm_exec_sql_text(sql_handle) AS s2 order by start_time asc Which is fairly useful... it gives a snapshot of everything that's running right at that moment against your SQL server. What's nice is that even if your CPU is pegged at 100% for some reason and Activity Monitor is refusing to load (I'm sure some of you have been there) this query still returns and you can see what query is killing your DB. When I run this, or Activity Monitor during the times that SQL has begun to slow down I don't see any specific queries causing the issue - they are ALL running slower across the board. If I restart the MS SQL Service then everything is fine, it speeds right up - for a week or two until it happens again. Nothing that I can think of has changed, but this just started a few months ago... Ideas? --Added Please note that when this database slowdown happens it doesn't matter if we are getting 100K page views an hour (busier time of day) or 10K page views an hour (slow time) the queries all take a longer time to complete than normal. The server isn't really under stress - the CPU isn't high, the disk usage doesn't seem to be out of control... it feels like index fragmentation or something of the sort but that doesn't seem to be the case. As far as pasting results of the query I pasted above I really can't do that. The Query above lists the login of the user performing the task, the entire query, etc etc.. and I'd really not like to hand out the names of my databases, tables, columns and the logins online :)... I can tell you that the queries running at that time are normal, standard queries for our site that run all the time, nothing out of the norm.
