• Benchmark an SSD

  - by Taylor Huston

  What is the best way to test/benchmark an SSD to make sure it's doing it's job. I invested in an SSD, have my OS on it, want to make sure I am getting my money's worth. I have heard some people making claims along the lines of: "I've had my SSD for X months and my read/write speeds have dropped Y%'. What is the best way to test for things like that (and what are good numbers to look for)? For reference I have a Samsung 830 128gb.

• How to use auto-discovery with iDRAC Enterprise?

  - by jwiz

  All I want to do is: have "auto discovery" enabled on my iDRAC enterprise at the factory rack the server, cable iDRAC to dhcp-enabled management network have the iDRAC DHCP, find the "Provisioning Server", and get updated with login credentials (for us to use with racadm, idrac webui, etc.) I don't need to do any configuring of the system, install OS, or anything else. I just want idrac to dhcp out of the box, and end up with an account that can be used to login. All the docs I can find on Dell's site refer to a "Provisioning Server", but I honestly can't tell if they have some reference product, or if they only have software that "integrates" with other vendor's existing management systems. I'd be happy to set up whatever is needed, I just can't find something that explicitly describes the process (only references to the fact that it is supported).

• Advise about performance for local or remote SQL Server?

  - by TruMan1

  I currently have my web server and SQL Express / MySQL server on the same server. It is on a VPS. I have been having problems with my hosting so I am thinking of separating the web and db server into 2 VPS servers. Does anyone recommend this? I am worried that changing my setup from a local DB server to a remote one will degrade performance heavily. They will not be on the same network, but will reference each other via an IP address. Anything I should be aware of?

• Finding X on Excel scatter plot/trend line

  - by Wilka

  If I have some data in an scatter plot in Excel, e.g. X Y 1 10 2 20 3 30 4 40 5 50 and I want to find the Y value for X = 10, or X=3.5, or whatever (obviously this is a simplified example) I've been doing the following: Add a trend-line to the scatter plot data Format the trend-line to one that fits the data (linear in this case) Display the equation for the trend-line on the chart Type the equation into an empty cell, replacing x with a cell reference. E.g. "=10*A1" then put my X value into the cell A1 Is there a better way of doing this with Excel? It's quite a few steps, and fairly repetitive. Or maybe Excel is just a poor choice of application for doing this? (I'm using Excel 2007)

• Determining what files are considered open in Mac OSX

  - by Doug

  Hi all; Apologies if this has been discussed previously... I did a stack overflow and google search but probably didn't use the right keywords. Anyway, is there an easy way to determine what files are open on Mac OS X? I had an issue in which I could not unmount a firewire HD until I closed all running apps. Turns out keychain access had a reference to a file on the HD, but it begged the question: how to find out what files are open and what app (or apps) has the file open? Thanks in advance and again apologies if this has been covered previously. Doug.

• Ngingx wont start with fastcgi_split_path_info" error

  - by Ke

  Hi, I heard that nginx is faster and since im on a VPS with low ram i thought id try it out. I got through this tutorial http://www.howtoforge.com/installing-php-5.3-nginx-and-php-fpm-on-ubuntu-debian But I now get the following error: unknown directive "fastcgi_split_path_info" in /etc/nginx/sites-enabled/default:28 Anyone know what might be causing the problem? I cant find any reference to the problem on Google Also I have heard conflicting things about Nginx vs Apache. Some say use one, some say the other. Im using allsorts such as rewrite rules, proxies etc. Am I setting myself up for a fall by using Nginx? If I go for apache, does anyone know of anyway to tweak it so that it performs better on a low ram VPS? Cheers Ke

• How to read the statistics in Media Player Classic?

  - by netvope

  I understand that the two numbers under bitrate are the average bitrate and the current bitrate of the stream. But what are the two numbers under buffers? I suppose the second one is the amount of data loaded in memory, but what is the first number? The amount of data decoded? Also, why are there a jitter and a sync offset? (For your reference, here stream 0-6 are video, audio track 1, audio track 2, subtitle track 1 and subtitle track 2.)

• Upgrade AirPort on Macs to support Snow Leopard's Wake on Wireless/WLAN?

  - by wojo

  Snow Leopard now supports Wake on WLAN, but not all hardware supports this. For example, my Octo Mac Pro from early 2008 has an AirPort card, but it does not support this. Nor does my 2007 2.33GHz MacBook Pro. For reference to what is needed, look at http://www.macrumors.com/2009/08/28/a-closer-look-at-snow-leopards-wake-on-demand-feature/ which includes a screenshot of what the System Profiler should show. It's pretty hard to find Apple parts, but is it possible to put newer cards into these machines to have them support Wake on Wireless?

• Windows7 IIS7: zips don't have php5isapi.dll Can I use php.dll instead?

  - by Pete Alvin

  The page: How to Install PHP 5.2 on IIS 7and Windows Vista (and a few others) reference a mysterious php5isapi.dll which is not in the Windows install, or the zip files: php-5.3.2-Win32-VC9-x86.zip - VC9 x86 Thread Safe php-5.3.2-nts-Win32-VC9-x86.zip - VC9 x86 Non Thread Safe There was another post on stackoverflow that said it's obsolete and replaced by "fastapi" but no instructions mention this. I did find a php.dll in the zip file. Can I use that instead of php5isapi.dll? It's very frustrating trying to install basic PHP5 on Windows with MySQL.

• Opening offline version of Microsoft Books Online in browser

  - by ercan

  I often use the MSDN website for language reference. In order to make navigation faster, I downloaded the offline version of SQL Server 2005 Books Online from here: http://www.microsoft.com/downloads/details.aspx?familyid=be6a2c5d-00df-4220-b133-29c1e0b6585f&displaylang=en The reason why it is 137MB is that it comes with its own GUI, which, not surprisingly, is rather poor! Apparently though, the pages are written in html. The URIs look like: ms-help://MS.SQLCC.v9/sqlcc9/html/674933a8-e423-4d44-a39b-2a997e2c2333.htm . I can open the URI in IE, but with errors. Do you know if I can open them with Firefox and how? Or is there a simple HTML version of "MS Books Online", for example in a ZIP file?

• New LAMP server, all links redirecting to localhost

  - by serilain

  I've got a very frustrating issue with what should be a bespoke install of Ubuntu 12.04, the LAMP config provided in apt-get install lamp-server^, and a web application called The Fascinator. After installing those three things and making no changes to any of them, I can access the application through a public IP (http://lib-hf1.lib.sfu.ca:9997 for the curious), but the domain of every link within that page is changed to localhost, including links to images and CSS, so nothing loads correctly and all of the links are broken. I've Googled around and found some people who appear to be having this issue with WP and Drupal, but nothing makes reference to a system-wide setting, and no one using the Fascinator seems to be having this issue. I have a faint memory that this might have something to do with mod_rewrite, but I'm pretty well stumped.

• Conditionally format row based on cell value in Excel 2011 Mac

  - by kojiro

  I'm using Excel Mac 2011. I have read some of the other answers, but this question is different because I want to apply conditional formatting to an entire row when its cell in column B contains the value 'Y'. Simple conditional formatting just formats that one cell. Whenever the field at column B for any given row contains the value 'Y', I'd like to format that row. Using Mac Excel's so-called "classic" conditional formatting, I have this: I would really like to apply that to every row, but it just paints the entire sheet red (because $B$3 contains "Y"). I can't seem to figure out how to get the reference to whatever is in field B for this row in the rule.

• CloudFormation - How to start a Windows Service with cfn-init

  - by Edwin

  I'm creating a CloudFormation Stack that will install and start a service on a Windows Instance. I've figured out how to install the service, but how do I start the service using cfn-init? The examples seem to all use linux, as there is a reference to "sysvinit" How do I structure AWS::CloudFormation::Init so that cfn-init will start windows services after installing them? Do I leave in the sysvinit, replace it with something else, take it out? ps: I'm referring to how to start services by providing information to AWS::CloudFormation::Init.services. Also, It would be nice to know how "packages" work for windows. AWS's announcemnet says that packages are supported on Windows but there is no Windows specific documentation

• What is the list of special variables available when writing a shell command for a context menu

  - by giovanni.pellicciotta

  When extending the Windows' shell context menu (e.g. for adding an 'Open command here' prompt on directories), a 'command' key needs to be created in the registry. The value of this 'command' key apparently can be any valid command line. I want to know which 'special variables' are available for use inside this command line. For example, I use following command for opening and cmd window from within a directory's context menu (*): cmd.exe /e:on /f:on /s /k pushd "%V" I cannot find any reference to what %V actually means or what the full list of such variables is. (*) Following registry keys are created for this: [HKEY_LOCAL_MACHINE\SOFTWARE\Classes\Directory\shell\cmdshell] @=Open Command Prompt Here" HKEY_LOCAL_MACHINE\SOFTWARE\Classes\Directory\shell\cmdshell\command] @="cmd.exe /e:on /f:on /s /k pushd \"%V\""

• Verify server performance

  - by George Kesler

  I'm looking for a quick and SIMPLE way to verify that new servers are performing as expected. The most important metric is disk performance, second is network performance. I’m trying to prevent problems caused by misconfiguration of RAID arrays, NIC teaming etc. The solution should work with both physical and virtual servers. I don’t need sophisticated analysis with different workloads, just one set of benchmarks which I would run against a reference server and later compare to new ones. One problem is that most benchmarks are not giving accurate results when running on a VM.

• What's using up my memory?

  - by Mehrdad

  I already know what's causing this -- it's the driver for FancyCache, which I'd installed myself. But as you can see, nothing in the screenshot tells me anything about this. I just happen to know. So the question is, if I didn't know this, how would I figure out what's using up so much of my RAM? (For reference: It's currently 1.7 GiB used, and the "missing" amount -- for FancyCache -- is 512 MiB. Clearly, that extra half-gigabyte not showing up anywhere I can see below.)

  I have a EC2 Instance with apchane, PHP and phpmyadmin. I have connect phpmyadmin to manage the aws RDS server. they are in the same security group. But when i try to use a php script to connect to the AWS rds server, it gave me SQLSTATE[HY000] [2003] Can't connect to MySQL server on (xxx.xxx.xxx.xxx).

• Stuck in power saving mode

  - by sazabi02

  I've got an LG monitor I tried attaching to my laptop for dual monitor goodness and it worked fine but when I tried attaching it back to the desktop it stuck in "Power Saving mode" and wouldn't go away. The CPU's starting up but nothing happens with the monitor. I try attaching it back to the laptop and it works fine again. I don't understand what could have happened. For reference, the laptop I'm using is an HP laptop with nVidia GT240M video card running on an i7 processor while the desktop runs on a Dual Core processor with an nVidia 9400GT video card. I've never had problems like these with other monitors I've attached my pc to. Anyone got any ideas?

• Apache 2.0.55/PHP 5.3.5 Hangs

  - by Rushyo

  Recently inherited a Windows 2k3 server running XAMPP, including ancient copies of PHP, MySQL and Apache. I'm attempting to install a second, up-to-date PHP installation on the machine so I can reference that in future instead of XAMPP's old one. Apache starts up with this new PHP installation happily. Unfortunately, when Apache references the new PHP install, whenever I try a view a page (even a non-PHP page) it hangs. The server simply doesn't respond to any HTTP request - it doesn't crash either. It just sits there with the connection open. There are no errors/warnings/notices in either the PHP or Apache logs. I've pretty much ruled out PHP's extensions (by process of systematic elimination) and most of the INI settings. I've tried reinstalling PHP from scratch. The PHP installation is PHP 5.3.5 x86 thread-safe compiled w/ VC6. The Apache installation is Apache 2.0.55. Anyone encountered similar behaviour?

• Gvim displays wrong font when set from _gvimrc, but correct font when set from menus

  - by dggoldst

  This question applies to gVim running on Windows. I have the following line in my _gvimrc set guifont=Lucida_Sans_Typewriter:h11:cANSI When gVim starts up, it strange italicizes everything! A call to :set guifont shows that things seem to have been set correctly, as it returns guifont=Lucida_Sans_Typewriter:h11:cANSI Then I manually select Edit-Select Font ... and then choose Lucida Sans Typewriter, and font size 11 and submit, the italics disappear and it looks fine. I've posted my _gvimrc for reference at http://vim.pastey.net/132157 So my questions are: Why am I getting different results from setting it manually and from _gvimrc? Is there a way to capture the command that the dialog box is sending back to the program? It might include extra commands that I'm missing.

• MySQL Workbench sends computer name with login not IP

  - by Android Addict

  I am attempting to connect MySQLWorkbench to a remote MySQL Server. The server has granted access to user@IPAddress However, when I try to connect MySQLWorkbench, it sends user@computername instead. How do I configure the connection to use the IP address instead in MySQLWorkbench? Reference: The remote server is on the local network, so I need to use the local IP address assigned to my client. EDIT What I have tried so far: from the server: mysql -u user@IPAddress -p --host=(ServerIPAddress) Returns: mysql> So that tells me the user account is operational. Furthermore, I confirmed it exists using: select user from mysql.user; returning a table of all users, of which the user I am using is present. I have also opened the port 3306: sbin/iptables -A INPUT -i eth0 -s clientIPAddress -p tcp --destination-port3306 -j ACCEPT Still I encounter Access Denied

• Ubuntu: On-screen keyboard

  - by Paul Lammertsma

  On a similar note to this question, I recently booted Ubuntu to recover a Windows partition, but couldn't in any way get the keyboard to register. I recall back in 8.x that you could easily reach the on-screen keyboard (Virtual Keyboard?) via "Assistive Technologies". It seems to have disappeared since 9.x. For future reference, how can I easily get to it? Recall that in this scenario I won't have a keyboard to enter terminal commands (e.g. to install xkbd or something of the like).

• PowerChute for VMware ESX4

  - by ITGuy24

  Hi, I am looking for a free way of installing PowerChute for VMWare. The 2.2.3 and 2.2.4 Linux versions do not support VMWare ESX even though I think prior versions did. APC is now charging $100 for the install CD which I think is a joke considering the price of our Symmetra UPS. VMWare support should be free. Edit: I see someone voted this question to be closed, so to be clear i am looking for a free and legal way of getting PowerChute support for VMWare, by either using an older version or a custom script. Also for future reference if you are voting to close a questions please leave a comment explaining why.
