• cannot mount remote partition using fstab/fuse

  - by HorusKol

  Using a combination of http://ubuntu-tutorials.com/2007/01/02/mount-remote-directories-securely-with-ssh-ubuntu-6061-610/ and http://www.tuxfiles.org/linuxhelp/fstab.html I figured I could mount the root of another computer to somewhere on my new laptop to make it easier to transfer files and stuff. Now, I can connect through SSH and browser the files through an ad-hoc mount - but I would like to be able to do this automatically, and so had a look at fstab. my new entry in fstab is: remote_comp:/ /var/remote_comp fuse defaults 0 0 but testing with mount -a results in the following error: /bin/sh: remote_comp:/: not found I thought the problem was because I was trying to mount the root of the other computer, but even trying sub-directories result in the same error message.

• Black Screen after Resume from Sleep (Kubuntu)

  - by user20271

  I know there is a lot of other posts like this, but I have been looking for hours and I still haven't found any solution. I have recently installed Kubuntu Linux along side my Windows 7, the sleep on my Win7 works fine and resumes like normal. When I am loaded into Kubuntu, and I put my laptop to sleep, it goes into sleep as normal. When I go to RESUME from the sleep, the screen stays solid black, it doesn't light up, no blinking curser or anything. The Wi-Fi light is 'off' (orange) and I cannot turn it on. The Caps lock and the Num lock lights on the keyboard blink slowly. I hear something on the inside of the computer start to spin. I am not very experienced with Kubuntu/Linux, but I do know a bunch of computer terminology, I am still far from an expert though. I have about 300GB designated to my Win7 stuff, and another partition with about 100GB for my Kubuntu Linux. My computers specs are as follows: Windows 7 64-bit I have the most recent version of Kubuntu because I just downloaded it a few days ago and updated it yesterday. AMD Athlon Duel-Core processor 4GB of RAM And it is a HP G61 Laptop

• Why does a website server recieve local files much slower than recieve files on other websites?

  - by T...

  The server at http://any2djvu.djvuzone.org receives same files from local computers much slower than from links on other websites (with the same files have been uploaded to the other websites, such as dropbox.com). The speed of uploading a file from local computers to other websites such as dropbox is also much faster than to any2djvu website. For example, a pdf file of 17MB needs more than 1 min to be uploaded to any2djvu server from a local computer with normal ISP such as Comcast High-speed internet, but takes less than 3 seconds from a dropbox link to any2djvu server, and takes around 10 seconds from the same local computer to dropbox. I wonder why there is such big differences for the speeds of different uploading ways to a web server? Thanks!

• Brand new battery is 100% charged but at 0% capacity

  - by Chris Conway

  I just bought a brand new battery to replace one that had seemingly died. I followed the instructions that came with the battery and charged it overnight, then ran my computer on battery until it was in a critical state and charged it overnight again. Now the battery appears to be 100% charged and at the same time at 0% capacity—when it's plugged in it doesn't charge and when it's unplugged the computer immediately goes into low power mode. I've taken the battery out and checked the contacts. I've rebooted the system with and without the battery. Nothing seems to help. I'm not sure if I should blame the battery, the laptop, the charger, or the power management software for this state of affairs. The obvious answer would be the battery but I bought this battery because another year-old battery exhibited similar behavior—I assumed it was dead and a Dell tech came to the same conclusion. I'm loathe to order another new battery without first exploring other explanations. What can I do to diagnose this problem? Here's the /proc info: $ cat /proc/acpi/battery/BAT0/state present: yes capacity state: critical charging state: charged present rate: 1 mA remaining capacity: 0 mAh present voltage: 9754 mV $ cat /proc/acpi/battery/BAT0/info present: yes design capacity: 6600 mAh last full capacity: 6789 mAh battery technology: rechargeable design voltage: 11100 mV design capacity warning: 660 mAh design capacity low: 200 mAh cycle count: 0 capacity granularity 1: 66 mAh capacity granularity 2: 66 mAh model number: DELL WK serial number: 4043 battery type: LION OEM info: SMP

• No "Choose OS" screen after co-installation of Ubuntu 12.04

  - by Léon McGregor

  I don't have any technical knowledge of Ubuntu but wanted to install it on a partition. Step-by-step of what i did. used disk management in windows 7 to clear 50gb of space used a usb live ubuntu 12.04 installer in custom install mode used the installer's built in disk manager to set up 2gb swap space and 48gb ext4 space ran installation, with option to copy over documents and settings from windows 7 restarted after completion. After this, my computer automatically loads ubuntu 12 and skips the option to load windows 7. i know the files are still there, as i can see them in the file manager. When trying to fix with the win7 installer dvd it tries to repair the OS in drive [D:] i.e. it recognises the disc itself as the OS and ignores the [c:] files. I think, after browsing around here, similar problems suggest this is a problem with the boot loader, but if the win7 dvd won't work, then i don't have any way to fix this. does anyone know of a way to force the computer to show a "choose OS" screen?

• Remote monitoring with screen capture

  - by Anonymous

  Is there anyway i can perodically take screenshots of a remote computer using nagios? I am experimenting with Nagios, and i am trying to explore different monitoring. So my question is apart from using nagios to monitor cpu usage, bandwidth utilization, uptime etc.. can i monitor my worker's productivity by checking what is he doing on his computer in a form of image output. Being able to monitor processes would not be of much help to me, as i only know if he or she is running firefox.exe for example he maybe using excessive use of firefox for facebook or other stuff but he claims he is troubleshooting and looking for solutions on forums. I saw a check_vnc script but i am unable to install the requsite vnc server anyone succesfully tried the vnc script care to share how to go about it? If not anyother way to try this?

• What You Said: How You Track Your Time

  - by Jason Fitzpatrick

  Earlier this week we asked you to share your favorite time tracking tips, tricks, and tools. Now we’re back to highlight the techniques HTG readers use to keep tabs on their time. While more than one of you expressed confusion over the idea of tracking how you spend all your time, many of you were more than happy to share the reasons for and the methods you use to stay on top of your time expenditures. Scott uses a fluid and flexible project management tool: I use kanbanflow.com, with two boards to manage task prioritisation and backlog. One board called ‘Current Work’ has three columns ‘Do Today’, ‘In Progress’ and ‘Done’. The other is called ‘Backlog’, which splits tasks into priority groups – ‘Distractions (NU+NI)’, ‘Goals (NU+I)’, ‘Interruptions (U+NI)’, ‘Interruptions (U+NI)’ and ‘Critical (U+I)’, where U is Urgent and I is Important (and N is Not). At the end of each day, I move things from my Backlog to my ‘Current Work’ board, with the idea to keep complete Goals before they become Critical. That way I can focus on ‘Current Work’ Do Today so I don’t feel overwhelmed and can plan my day. As priorities change or interruptions pop up, it’s just a matter of moving tasks between boards. I have both tabs open in my browser all day – this is probably good for knowledge workers strapped to their desk, not so good for those in meetings all day. In that case, go with the calendar on your phone. While the above description might make it sound really technical, we took the cloud-based app for a spin and found the interface to be very flexible and easy to use.

• Display won't come back from power saver mode

  - by tynor

  I wan't sure where exactly to post this question, but this one seemed the most relevant. I have a Dell LCD monitor running off a Dell Inspiron 531 tower with an Nvidia GeForce 8600 GT video card. Just recently, when I turn my computer on, the display immediately enters its "Power Saver" mode, and never wakes up. This problem doesn't occur with other computers, or even with this same computer when I use the integrated graphics. I have no other displays to test the card on. I have also tried replacing the power supply (my original one, which ran that video card for 4 years, was 300w, and I replaced it with 500w). Is there anything else I can try to troubleshoot this issue?

• How can I access my music anywhere?

  - by musicfreak

  So here's the idea: I use multiple computers on an almost daily basis. I would like to be able to access my entire music library from any of those computers through the Internet. Is there a service or perhaps some software that would allow me to host my music "in the cloud", or in some other way access it from a different computer? I've searched for something like this and the closest I've found is the Media Player application found in Opera Unite, but that requires my home computer to be turned on at all times, which is less than ideal. I'm willing to pay, but not so much that I could just rent a private server for a lower price. Thanks in advance.

• winusb formatting and installation error, lost data storage on 32gb flash drive

  - by Cary Felton

  i recently purchased a pny brand 32gb usb drive to use for configuring a dual boot on my computer, and for hdd files backup. i also recently installed zorin os 6.1 as my main os, and then downloaded winusb for linux, and set it to install the iso for windows 8 release preview as the activation code is still good untill jan.2013, and there was an error on the installation. i rebooted the computer, plugged in the usb drive, and i went from 32gb usable space to somehow having a partitioned drive (mounted as two separate drives) one being 3.7gb, and the other being i believe 25gb or so... i then formatted the drive with gparted back to fat32, and it still read as a windows usb with the installation files on it still? so then i took my usb drive to my library which runs windows 8, i installed bootice, and completely reformatted my usb drive, and somehow it is usable, but still not perfect. it reads i only have 29.9gb usable space... i have already thought of the non usable area, and that doesnt account for this error as when i first bought the drive and plugged it in on linux, it read total drive space was 32.2 and exactly 32 was usable. somehow i am short by 2gb of space which is very critical for what i am doing. i love linux, i only needed windows for bluray playback with daplayer as it wont work well in wine, but if i keep losing space on my usb drives im afraid ill have to switch back. any help would be appreciated as i already visited pny's site, and they have no support for this issue, and im not that fond of partitions, file systems, or formatting.

• Stop VLC player from saving effects & filter settings

  - by bocamax

  VLC Player v1.1.11 Windows 7 Ultimate VLC player launches each new video with setting I used once to brighten a dark video. On a second computer, VLC player opens all videos rotated 270 which was a feature I used once. I now have to manually uncheck Image adjust on one computer & uncheck Transform on another for each video to have it play without these custom settings. I've custom mapped VLC Hotkeys that I use extensively. As a result, I do not want to "reset preferences" and lose my Hotkey mapping. VLC Tools Settings Video Effects Basic Image Adjust (Brightness, Contrast, etc.) VLC Tools Settings Video Effects Basic Transform (Rotate 90, 180, 270) Is there a setting I'm not finding to stop VLC from applying a one time adjustment to all videos?

• Mythbusters &ndash; SQL Edition

  - by AjarnMark

  I love the Mythbusters television show.  That has to be one of the coolest jobs in the world…it involves investigation, problem solving, science, trial & error, searching for the truth, robotics and remote controls, and in the end, you usually get to blow stuff up.  How great is that?!  I know I’ll never forget the episode where they blew up a cement truck.  That was truly awesome. Well, perhaps not quite made for TV, but pretty cool nonetheless, Paul Randal (@PaulRandal) has been doing some SQL Server myth busting here in the month of April with his DBA Myth a Day series.  It starts with In-Flight Transactions Continue After a Failover.  Check it out!

• Cannot move/drag/drop windows/items in remote VNC session

  - by hansioux

  I find it a little hard to believe that no one here has asked this question, I tried searching for it but it isn't asked, so here goes: I setup a Ubuntu desktop computer with VNC to use as a server. And use another Ubuntu desktop computer to VNC into it. The rest of the VNC works ok, but drag and drop with mouse is gone. Thus I can not move windows, or drag and drop items via VNC. I am using the default remote desktop in System - Preferences to setup my server. And use Remmina as my client. The same happens using MS Windows's VNC clients connecting to my Ubuntu desktop. I did a bit of searching on google, and there are actually a lot of reports regarding this issue. But, oddly there is no solution. There are even bug reports made for this since Ubuntu 9.10, yet here it still is in Ubuntu 11.04. There have been suggestions that the bugs is in gtk, as see in link below: http://ubuntuforums.org/showthread.php?t=1497635&page=2 libgtk2.0-0 stable(lenny) -> DnD works libgtk2.0-0 lenny-backport (libgtk2.0-0_2.18.6-1~bpo50+1_i386) -> DnD still works libgtk2.0-0 testing (libgtk2.0-0_2.20.1-2_i386) -> DnD broken please don't give answers such as "use NX", "use ssh -x" or "use x11vnc". I am aware that some people don't have this problem with x11vnc, and I have setup x11vnc before, but i can't for this setup. I am setting this up so Windows only friends/families can use it.

• How to install Windows 7 From Network?

  - by George

  Hello SuperUser My question is that is it possible to install Windows 7 (Current RTM Version) on a computer without using removable media like DVD or USB. First thing that comes to my mind is network but i dont have experience of doing Fresh Install of Windows 7 via Network. How to install Windows 7 via network without any removable media? P.S. I know some may think that doing so, is just a waste of time and it's easier to do it with removable media, but in current situation the target PC neather has CD/DVD Drive nor supports booting from USB. And in addition to that, Target computer is connected to Network via Wireless Network (Dunno if it will make any problem with installation).

• Small Business Server services will not start, and remote desktop and UAC are broken

  - by Stephen Jennings

  Yesterday I began setting up a server with Windows Small Business Server 2008. All I am configuring it for right now is to be a domain controller and Exchange server. I completed the initial setup of SBS then started looking through different connection options (allowing VPN versus using a TS Gateway). After I rebooted one time, I started having three not-obviously-related issues: First, I could no longer remote desktop into the computer. I ran TCPView and saw that it was no longer listening on port 3389. I checked everything in Terminal Service Configuration but everything shows the computer ought to be allowing connections. Also, when I tried to use anything that required user account control elevation, the UAC dialog never popped up and the program that was waiting just froze. If I try to run "regedit" from the Run box, for example, it never appears. When I run in safe mode which does not run with UAC, I was able to access everything. I didn't want to deal with it, so I turned off UAC and rebooted. Finally, in the Windows SBS Console, there are status indicators for Security, Updates, Backup, and Other Alerts. The first three get stuck saying "Querying". Looking in the computer alerts, I have events showing the following services stopped: Background Intelligent Transfer Service KtmRm for Distributed Transaction Coordinator Distributed Transaction Coordinator Microsoft Exchange Information Store Microsoft Exchange System Attendant Microsoft Exchange Transport Windows Remote Management Update Services Windows Update I figured I must have configured something wrong accidentally and I couldn't find anything using Google explaining what might be the case, so I just decided to format the hard drive and reinstall SBS from scratch. I did this and everything was working last night, but I just turned the machine back on and it is doing the same thing again! On my second install, I did not configure anything except the following (all from SBS Console): Connect to the Internet (set IP and router address) Turn off customer feedback. Set up internet address. Decline to use a Smart Host for email. Added one standard user account. Since this happened again and I was very careful the second time not to configure anything outside of the SBS Console, I feel like there's something else going on. Right now the machine is on an isolated network that does have internet access. My desktop is the only other machine plugged into this network. Any and all help is appreciated (before I tear my hair out!)

• Quiet Sound while recording using the "Stereo Mix" option on Windows XP.

  - by DragoonX

  I'm trying to record some of my work, and the video capture program I'm using works fine. It's HyperCam2, and since it's not really professional, I don't care about that little thing in the corner. Anyways, If I check the record sound option and put it on the highest quality, and I want it to record the sounds playing from my computer, I have it record the "Stereo Mix" setting. However, after a quick test, I saw that even though my computer was at max volume, the recorded sound was very quiet, almost inaudible. Thinking it was just HyperCam, I downloaded Audacity, and only met similar results. While I'm not entirely savvy with hardware, I BELIEVE this to be my soundcard: SoundMAX Integrated Digital HD Audio

• Multi database link and mix and match email alert

  - by menardmam

  I have a site which is a large database of people that have different knowledge in different domains, such as teaching (maths, french, science etc...) On the site there is a page where you can search people base on different request, such as distance from home, grade, sex. Now, I would like to add a page where people that are looking for mentor will fill a request, and when a tutor in his area of search will match request, a email will be send to this researcher. Because I know for sure, that when in January you look for a math teacher for your 10 year old son, and you find none, you won't go again in February, March... and on and on just to see. Maybe there is one now, you want to be informed when the tutor will get into database automatically (more or less like www.jobboom.com) So the question is, what CMS do I need to be able to do that ? Wordpress, drupal or something custom made?

• How Microwave Ovens Work [Video]

  - by Jason Fitzpatrick

  In this informative how-it-works video, we’re treated to a peek inside the common microwave and the science behind the magnetron that powers it. Bill details how a microwave oven heats food. He describes how the microwave vacuum tube, called a magnetron, generates radio frequencies that cause the water in food to rotate back and forth. He shows the standing wave inside the oven, and notes how you can measure the wavelength with melted cheese. He concludes by describing how a magnetron generates radio waves.

Later i realized that there was no admin set up on the pc (when switching user). Now with the security settings changed I can't do anything on the computer. I can only read the files that previously existed. And this applies to every drive on my computer. Now the user accounts do not have the privileges to change the permissions.

• Optimizing lifestyle and training

  - by Gabe

  I am a college freshman who has recently discovered a passion for computer science. Having had my first lick of formal python training last semester, I have cast aside my previously hedonist way of life and tunneled my sights on becoming the most rounded and proficient programmer I can be. I know that I'm taking strides in the right direction (I've stopped smoking, I've been exercising every day, I've taught myself C++ and OpenGL, and I've begun training in kung-fu and meditation), yet I am still finding myself struggling to achieve satisfactory results. I would like to be able to spend a good 3-4 hours every day burning through textbooks. I have the time cleared and the resources allocated. The problem lies in the logistics-- I have never taken anything seriously before. Recently I've realized that I am clueless when it comes to taking care of myself and gaining control of my mind, and it drastically hinders my productivity. My question is this: How can I learn to manage my time and take care of myself such that I can spend the maximum amount of time every day studying with steady concentration? Personal tricks would be key here: techniques you use to get yourself to sleep, a diet that yields focus, even computer break stretching routines or active reading techniques. Anything you could think of here would be great. I was a low-life in high school and I have the drive to turn my life around, I'm just quite a bit behind in the way of good habits :)
