• Post Error, Fixed/Removable Media Error

  - by Dan

  Hi, I really do not know what I am missing here. I ordered parts for a new server. The board is an Intel s3420GP. From the diagnostic LEDs I get the error message: 0xB1h which corresponds to "Fixed Media: Disabling fixed media" and 0xB8h which corresponds to "Removable Media: Resetting removable media device." I can not for the life of me figure out what it is talking about. I have two identical motherboards and both gave the error message. I don't have a second CPU yet, so I can't test that. There are no beeps or anything. It seems the server resets every 10 seconds or so (the speaker does work, I put the RAM in the wrong slots on purpose to test this out, and the correct error POST code came up) Please help me, I'm not sure where else to turn or to ask

• Software to automate website screenshot capture

  - by Leniel Macaferi

  Do you know any software that can automate the process of getting screenshots of every page of a website? It would act like a spider/crawler/robot. You name it... For example: I developed a website and now I'd like to get a screenshot of every page of the site. I of course could do it manually (a lot of work). For each module of the site (Student, Payment, etc) I have different pages (Create, Edit, Details, Delete, etc) forms. The thing I'm looking for is a software that can visit every link of the site and then capture the screen - a software that can automate the whole process. It would also be good if the software allowed the user to pass a list of URLs to capture screenshots allowing even more fine grained configuration. EDIT: I tried Selenium mentioned by Aaron in his answer but I managed to find an app that does exactly what I needed. It's called Paparazzi!. I wrote a blog post to showcase my attempt at Selenium and the findings regarding Paparazzi!'s batch capture functionality: Software to automate website screenshot capture

• How do you explain more advanced computing concepts to a non super user?

  - by EvilChookie

  I often have to explain computing concepts to non super users, and I often do it by relating computing concepts to real life situations. I wouldn't mind seeing how other super users do it, and some really good explanations might come in handy instead of me having to wing it. So, how do you explain advanced computing topics to the 'normal' people? Notes: One explanation per answer, and let the best float to the top. CW turned on, since this is subjective. Also, feel free to edit my tags if you can think of better ones =)

• Automated method to convert .reg registry file to reg.exe commands

  - by nhinkle

  Occasionally I need to put registry entries into batch files to use in login scripts, unattended installers, etc. While it's pretty easy to add one or two registry commands to a batch file using reg.exe, when there is a large amount of registry data, it becomes tedious. I usually just end up merging an external reg file in those cases, which I would like to avoid, since it ruins the self-contained nature of the batch file. Does anybody know of any tools which can automatically convert a .reg file to a series of REG ADD and REG DELETE commands? This would make life a lot easier! Thanks.

• how to install mpgtx from source code

  - by Ahmet vardar

  i am new on linux server. i have mpgtx folder in my root, how can i install it ? in readme file it is written; ./configure && make when i type this i get permission denied error ? thanks EDIT: Here the steps i done root@server [/]# cd /mpgtx root@server [/mpgtx]# ./configure -bash: ./configure: Permission denied root@server [/mpgtx]# make ----------------------------------------------------------------------------- Hello ! I'm afraid I'm a dummy Makefile. My goal in life is to politely ask you to run the configure script to actual- ly generate a real Makefile. Would you be kind enough to type "./configure --help" to see the options that will suit your needs ? Please note that typing "./configure" without option will generate a Makefile that will suit most people needs. I wish you a good day. Please don't drive to fast. ----------------------------------------------------------------------------- root@server [/mpgtx]# ./configure -bash: ./configure: Permission denied root@server [/mpgtx]#

• Kanji characters appear as boxes

  - by s3d10s

  i'm having trouble with the display of japanese characters on Windows 8 Pro (English, 64-bit, updated regularly). They appear as boxes (picture) in windows explorer, windows menus (even in the language settings of control panel), iTunes and nearly everywhere else, besides web browsers. I was using windows 7 until now, and it didn't have any of these problems, and i'm using the same applications now, as i was using in windows 7. Sometimes (!) when i restart the machine the problem goes away, but that isn't a real solution. What i've tried so far: added japanese language to windows of course installed/uninstalled/reinstalled japanase language pack (didn't have any impact though) i've read in one of these superuser topics a possible solution, when i had to create a txt file on the desktop with a kanji in the filename - that also didn't work (but i honestly hope that hacking and tweaking an operation system released in 2012 can't be the solution to display kanjis..) Please give me any ideas, i'm a bit hopeless here, and don't want to spend my life installing operation systems..

• open source solution to a gateway for a network of a housing cooperative of 150 people

  - by SirDinosaur

  i just inherited a barely functioning network for a student housing cooperative of about 150 people. in it's current state, as i understand it from the previous person in charge of the network, we have working wireless access points and working ethernet cords going to working gigabit switches going to a barely functioning gateway (right now a simple home router) to one of three possible outbound connections. it is possible to connect to the network through the wireless or ethernet, but especially during peak hours, packets / connections are likely dropped or otherwise get no response. my intuition tells me to replace the gateway with something that can handle multiple outbound connections (WAN) and one inbound connection (LAN), while the rest of the network seems suitable for now. i'm somewhat knowledgable in Linux (been using Debian after first Arch Linux) and i want to use as much open source as possible, but i'm confused whether or not a simple server that i could easily understand will work for this situation. do i need specialized hardware to handle the switching more effectively? if so, what are my options? (i found this, thoughts?) or if a Debian server would work, anything else i should about the specs required for this type of server? also links to any useful information on using open source to maintain this type of network would be most appreciated. <3 P.S. crossposted http://redd.it/yybp2.

• starting nginx via upstart

  - by Chiggsy

  Background: DISTRIB_ID=Ubuntu DISTRIB_RELEASE=10.04 DISTRIB_CODENAME=lucid DISTRIB_DESCRIPTION="Ubuntu 10.04 LTS" I've built nginx, and I'd like to use upstart to start it: nginx upstart script from the site: description "nginx http daemon" start on runlevel 2 stop on runlevel 0 stop on runlevel 1 stop on runlevel 6 console owner exec /usr/sbin/nginx -c /etc/nginx/nginx.conf -g "daemon off;" respawn I get "unknown job" when i try to use initctl to run it, which I just learned apparently means there is an error, ( what's wrong with "Error" to describe errors?) Can someone point me in the right direction ? I've read the documentation , as it is, and it seems kind of sparse for a SysV init replacement... but whatever just need to add this job to the list, run it, and get on with what's left of my life... Any tips? EDIT: initctl version init (upstart 0.6.5)

• Proven and Scalable Comet Server

  - by demetriusnunes

  What is the most proven, scalable comet server solution out there that can handle up to 100.000 real-life connections per node using HTTP streaming (not long-poll)? It must be a free, preferably open-source project. We've already tried Meteor (Perl), with no success. Meteor was able to scale just up to 20.000 connections per node. We are looking right now at these options: APE (C++), Orbited (Python), Grizzly (Glassfish), Cometd (Jetty). Any big success stories with any of these?

• What Firefox UI customisations can be used to improve productivity?

  - by Umber Ferrule

  Most desk jobs these days involve the frequent use of a web browser. What Firefox UI customisations increase your productivity and make your working life easier? Not necessarily add-ons (although no reason why not as long as they're UI-related), but I'm thinking more along the lines of toolbar removal/placement, icon/menu removal/placement, tweaks to userChrome.css etc. to make things more pleasant and optimal. Screenshots welcome. I realise some people feel UI customisation makes switching between machines harder. Whilst I agree to some extent, if you mainly use one machine, and it helps your productivity - why not?

• Listing pending reboots in windows

  - by Jake

  I'm trying to install SQL Server 2008 on a Windows Server 2008 x86 system, and I'm getting an error saying "Rule 'Restart computer' failed." I've already found a lot of people saying to clear the registry key HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\PendingFileRenameOperations, but sadly this key doesn't even exist in the registry on my server. I know I've run into this exact problem before, and that remedy did not work the previous time either. I eventually found a way to list the processes that currently require a reboot in Windows, which I used as a guide for what to uninstall. I cannot, for the life of me, find out how to do that again. Does anyone know how to list the pending required reboots in windows via command line or some other tool?

• Admin mode on Procurve Switches

  - by stefan.at.wpf

  Not being a network expert, I spent some time configuring my network, until I found my mistake: On my HP ProCurve Switch 1810G, I thought that "Admin mode" means whether the administrative interface can be accessed from this port. Well, it means whether the port is enabled or not. Extract from the help function: Admin Mode - Select to enable the port-control administration state. Click to enable and have the port participate in the network.(Default : Enabled ) Well, of course I didn't read the help, because I didn't doubt it's for the adminsitrative interface and suspected an error somewhere else. Anyway, I am wondering if that is a commonly used term for enabling/disabling ports or if HP just wanted to make my life harder? I can't understand why this option isn't just called "Enable port"!? Here's a screenshot of how it looks in the web interface (yeah, shame on me for using a web interface)

• Anyone know where I can download a copy of Sun Java System Active Server Pages 4.0.3 for Solaris

  - by ewengcameron

  I've contacted Sun regarding this and they have told me that the download is no longer available as Active Server Pages 4.0.3 is now End Of Life. We need to upgrade our server to 4.0.3 to acheive PCI-DSS compliance. Anyone know of a site where I can download older copies of Sun files? Sun offer 4.0.1 and 4.0.2 to download but not 4.0.3 which is going to cause problems come October when Visa stops accepting transactions from non PCI compliant servers. If Sun kept their naming system consistent across versions, the file would be called "sjsasp403-sol-sparc.tar". I know the real solution is to upgrade every site on the server to use a different server language, i.e. PHP, and in the long term, this is our goal but we have over 100 sites requiring upgrading and its not a viable solution to get this done before October.

• MacBook Pro - 72k vs 54k rpm drives - Heat and Noise

  - by webworm

  I am looking at a new 15" MacBook Pro for development purposes. I am planning to run a Virtual Machine for about 50% of my work (Windows 7 x64, IIS, SQL Server, and VS 2010). The upgrade from a 54000 rpm drive to a 72000 rpm is only $45. From what I understand the faster rotational speed of the 72000 rpm drive will help virtual machine performance. However, I am concerned that additional heat and fan noise might be an issue. I will be running mostly on A/C power so decreased battery life is not a major concern for me. Since I would be running with a Core i7 processor which gives off a fair amount of heat already I was wondering if it might be best to stay at 54000 rpm for the hard drive. What do you all think? Thanks!

• How do I access site.project.rails (running on host) from VMWare fusion?

  - by Johnny Mnemonic

  I have a rails app setup and running on my snow leopard MacBook - the app is being served by Passenger. As part of the setup they had me add entries for 127.0.0.1 site.project.rails in my hosts file so I could reach the site from site.project.rails I can't for the life of me figure out how to get the app show up in VMWare. I have XP setup and browse to http://site.project.rails and I can't get it to show up. I setup a basic rails app, being served at localhost:3000 by webrick, I can get that to load by visiting my hosts ip (http://192.168.1.1:3000/). I added the same hosts I added on my Mac to Windows. I also Bridged the network under settings for the VM. What am I missing?

• Can't connect to local SQL Server

  - by D.M.

  I'm banging my head against the wall here and can't get things figured out. Yesterday I uninstalled SQL Server 2008 Express and installed a full copy of SQL Server 2008 R2. Everything installed fine but I can't connect to the database to save my life. There is a similar question here that never got answered and I'm not sure if this may be specific to 2008 R2 and how I may have installed. Under my old configuration (SQL Express) I connected with "DM\SQLEXPRESS" just fine. So far I've tried: DM\MSSQLSERVER - .\MSSQLSERVER - \MSSQLSERVER - MSSQLSERVER - DM\Dave\MSSQLSERVER and I get the "cannot connect to server" error every time. I have the service installed as well as the SQL Server Browser that I have started. If anyone had any suggestions that would be great.

• Which tool do you use for tracking daily/weekly progress on your long-term goals?

  - by NoCatharsis

  I read through this post and this post to get an idea of short-term task management applications out there. However, now I'm having a problem tracking my longer-term goals pertaining to things like career, education, and exercise. I just discovered Disciplanner which might meet my needs but haven't had time to set it up just yet. Not to mention, it took me about 2 weeks of playing with every online to-do list app I could find before I came to a decision on which to use. I'm very particular about my tasks and goal-setting, so I would prefer to get some advice from other superusers before diving into the web again to find another life-management website.

• Monitoring remote laptops

  - by kaerast

  We're looking for something to monitor around 30 remote laptops that are constantly out on the road, never returning to base except for when there are serious hardware faults that need repairing. These laptops won't always be connected to the internet, they'll have mobile broadband and may work offline most of the time. They will be running a mixture of Windows XP, Vista and 7 and there is currently no server setup. We're primarily interested in making sure that Windows Updates and antivirus updates are happening, and I guess we should also be monitoring remaining disk space, what software is installed and ideally hardware health. It might also be nice if we could gain remote access to perform work on them. My main reason for wanting to monitor them is that it's going to be a real pain to get them back to base if anything goes wrong, so I want to be proactive in ensuring they last as long as possible. Can you recommend what I should be monitoring to ensure a long life? What tools would you use to monitor and maintain these computers?

• How to restore from file using Symantec NetBackup 7.5

  - by Tony

  I have an install of Symantec NetBackup 7.5 and I want to restore the server from a NetBackup image file. The file was created using NetBackup before I arrived. We had a hardware failure that corrupted this server and it needed to be rebuilt, now we want to restore from this image file. I can't for the life of me figure out how to restore from that file. I've installed the NetBackup application but it can't find the file when using the restore command within the application. If I double-click the file it opens the application then gives me the same "can't find any NetBackup files" error. I also can't simply drag the file into the NetBackup window. Any advice on how I restore from this file would be appreciated, thank you.

• 64bit on core i5 with 2GB DDR3 RAM?

  - by Jacques

  Core i5 2.3 Ghz processor 512mb ATI HD 4570 2GB 1333 RAM 64bit Windows 7 Home Premium. Should I "down-grade" to 32bit? Does running 64bit with only 2GB RAM make the laptop weaker than running 32bit with 2GB RAM or is the performance pretty much the same? Is there any performance benefit to running 64bit with only 2GB RAM? Is there an impact on battery life between 64bit and 32bit. Should I maybe just add another 2GB RAM? Thanks.

• Nvidia Optimus shows Nvidia card is always active in Windows 8

  - by Ty Underwood

  I have loaded the new Asus Nvidia driver for my Asus Ux32VD that I have installed Windows 8 on. It has an Nvidia 620m and Intel hd 4000 integrated graphics. The problem is that the Optimus activity icon in my system tray shows that the Nvidia card is always active, though it shows that it is not doing anything. I can force the system to prefer the Intel graphics, and after rebooting, the Nvidia card will shut off, but then all the programs will be overridden and use the Intel graphics. Is anyone else having problems with Optimus in Windows 8? My battery life is really suffering because I'm always idling my Nvidia card while also presumably running the Intel card. Any suggestions would be appreciated.

• Shopping for Fast USB Flash Drives

  - by Jim McKeeth

  I would like to pick up some really fast USB flash drives in the 16 - 64 GB range. When looking at drives they just list their size, their form factor (key chain hook, slider, etc.) and the fact that they are all Hi-Speed USB 2.0. It seems like I have heard that different drives have different performance and life expectancy. The sales guy tells me that they are all the same performance any more, but it wouldn't be the first time a sales guy had the wrong technical details. Our objective is to run Virtual PC images off of them, so good speed and resilience to rewrites it important.

• In what way does non-"full n-key rollover" hinder fast typists?

  - by Michael Kjörling

  Wikipedia claims (although the latter claim does not cite a source) that: High-end keyboards that provide full n-key rollover typically do so via a PS/2 interface as the USB mode most often used by operating systems has a maximum of only six keys plus modifiers that can be pressed at the same time.[4] This hinders fast typists, ... In what way would the system being able to recognize only six non-modifier keys at once hinder a fast typist? I consider myself a relatively fast typist and I usually press one key, plus modifiers, at once; I can't imagine any real-life situation in which the system only recognizing six non-modifier keys being pressed at once has been a limiting factor in my keyboard usage. (Multi-stroke keyboard shortcuts as used by high-end software like Visual Studio, Emacs and the like are a different matter.) Note that I am not really interested in answers centered around multiplayer computer games; I'm looking for answers that give reasons that would be relevant to typists, somehow supporting the statement made on Wikipedia.

• Nginx proxy to s3 bucket gets 400 Invalid Argument

  - by elssar

  I have a Django app in which I serve media files through an nginx proxy to s3. The relevant python code response = HttpResponse() response['X-Accel-Redirect'] = '/s3_redirect/%s' % filefield.url.replace('http://', '') response['Content-Disposition'] = 'attachment; filename=%s' % filefield.name return response The nginx block for the internal redirect is location ~* ^/s3_redirect/(.*) { internal; set $full_url http://$1; proxy_pass $full_url; And the request logged by s3 is.

The url send to nginx by the app is valid, it works in the browser. And nginx is sending a request to s3.
