• How is SU indexed so fast on Google?

  - by ekaj

  I just did a quick Google for a question that was 20 minutes old, to look for an answer, and it was already on Google Search - how is this possible? I glanced over this article which seems to suggest that SU has added RSS feeds (which SU has, but when I opened the feed the article says last posted 6 minutes ago, but when Googled it is 11 hours old) - which leads me to think (Based on that article, I don't know much about search indexing but I am reading at the moment) that most of this indexing is done thanks to the sitemap - is there anything else I am unaware of that helps SU questions get on Google so fast?

• Create tunnel through an open SSH connection?

  - by criptych

  I have a remote PC (behind NAT and firewall) set up to create a reverse SSH tunnel to my home PC/server (DMZed). Unfortunately, the tunnel hasn't been working lately. Fortunately -- I think -- the remote PC currently has an SFTP session open to the local one. My question is, can I create a tunnel back to the remote PC through that session? Or am I SOL until I can physically get in to restore the reverse tunnel on the remote PC?

• Protect Section in Word without limiting formatting in unprotected sections

  - by grom

  Steps to create protected section (in Word 2003): Insert - Break... Choose Section break, Continuous Tools - Protect Document... Enable 'Allow only this type of editing in the document' in editing restrictions In the drop down select 'Filling in forms' Click on 'Select sections...' and uncheck the unprotected sections (eg. Section 2) Click 'Yes, Start Enforcing Protection' and optionally set a password. Now go to the unprotected section and in the Format menu options like 'Bullets and Numbering...' and 'Borders and Shading...' are greyed out. How can you protect a section without limiting the features that can be used in the unprotected section?

• HLS video segmenting complications. How to create a transport stream with ffmpeg

  - by Agzam

  I have h264 videos, and currently we're using Apple's HTTP Video Streaming tools and mediafilesegmenter to segment these files. What I need to do is to switch to alternative segmenter based on this very popular open-sourced segmenter The problem is that this segmenter does not just take any video, but takes only MPEG-TS videos. So I have to convert my h264 videos to TS first. I can do that with ffmpeg. I'm using this: ffmpeg -i encoded.mp4 -vcodec h264 -i encoded.mp4 -sameq -acodec aac -strict experimental -f mpegts output.ts But this creates fairly larger output. And the reason is that Apple's segmenter keeps the same codec - AVC and the same audio codec - AAC, whereas ffmpeg changes video format to MPEG Video. The question is: can I somehow keep the same AVC video codec and still convert video to a transport stream? So my goal is to keep the same video quality and same video codecs as Apple's medifilesegmenter does. UPD: Okay... it seems that ffmpeg CAN split videos into segments: ffmpeg -i encoded.mp4 -c copy -map 0 -vbsf h264_mp4toannexb -f segment -segment_time 10 -segment_list test.m3u8 -segment_format mpegts segment%d.ts That's still has one problem: it doesn't create http live streaming index file. (-segment_list creates a file with list of segments, but it doesn't look like HLS index). So, you still have to create index file

• Commandline program to extract archives with automatic subdirectry detection

  - by ??????

  The title already says it. What I'm looking for is essentially the pure commandline counterpart to ark -ba <path> (on KDE), or file-roller -h <path> (on GNOME/Unity). Unfortunately, both ark and file-roller require X to be running. I'm aware that it is relatively simple to write a tool that detects archives based on their file extension, and then runs the appropiate program: #!/bin/bash if [[ -f "$1" ]] ; then case $1 in *.tar.bz2) tar xjvf $1 ;; *.tar.gz) tar xzvf $1 ;; *.bz2) bunzip2 $1 ;; *.rar) rar x $1 ;; *.gz) gunzip $1 ;; *.tar) tar xf $1 ;; *.tbz2) tar xjvf $1 ;; *.tgz) tar xzvf $1 ;; *.zip) unzip $1 ;; *.Z) uncompress $1 ;; *.7z) 7z x $1 ;; *) echo "'$1' cannot be extracted with this utility" ;; esac else echo "path '$1' does not exist or is not a file" fi However, that doesn't take care of subdirectory detection (and in fact, many extraction programs do not even supply such an option). So might there be a program that does exactly that? I wasn't sure whether or not to ask on askubuntu.com, because this question isn't really about Ubuntu, but rather about any Linux operating system. My apologies if this question does not fit in here.

• Internet speed is suddenly slow only on my laptop, but it's normal in other devices

  - by Wael

  I have a TP-Link router connected to a ZTE modem, with 2 laptops, a tablet, 2 phones connected via the router's WiFi, and an additional desktop connected via ethernet to the router. Today, my laptop started to have a very slow connection to the internet, which at first I thought it was the operator's problem to find out later on that it works fine on other devices. I tried to connect directly via WiFi to the modem, but it was as slow. I cannot access facebook at all, google takes forever to do a search, and youtube barely works. The weird thing though, is that when youtube does work, the streaming is full speed. This happens also when I download a file! My browse is Firefox, but I used Chrome and IE9 with the same results. I work on Windows 7 Thanks for any advices.

• sudo apt-get moo and other easter eggs in Linux

  - by Arkapravo

  I came across this command while dabbling in Ubuntu 9.10: sudo get-apt moo acer@acer:~$ sudo apt-get moo (__) (oo) /------\/ / | || * /\---/\ ~~ ~~ ...."Have you mooed today?"... Which most surprisingly "made a MOO". (How unfortunate for the cows). Does anyone else know of funny command line easter eggs in their flavour of Linux (Fedora, Slackwire, Mandriva, Solaris, Suse, etc)?

• Safari corrupting downloads?

  - by Kaji

  First off, a bit of background: I had to do an erase and install about 2-3 weeks ago, so this is a fresh, up-to-date installation of Snow Leopard we're dealing with. That said, I decided recently to branch out from simply programming PHP in a text editor and explore some of the other technologies I keep hearing about, and picked up Drupal, Joomla, and the Zend Framework from their respective official sites. Latest complete, stable builds for all 3. Drupal and Joomla downloaded without a problem, but when I put them in my /~username/Sites folder, XAMPP pretends they're not there, even if I restart Apache or the laptop itself. Zend's archive won't open at all. Is Safari corrupting the downloads, or are there other issues in play that can be investigated?

• What is the best / latest software to convert DVD recorder disc to YouTube?

  - by Jian Lin

  I recorded some Wii gameplay to a DVD-R using a DVD recorder, and tried using Handbrake to convert it to YouTube compatible format. Basically, it needs resizing to 16:9, and selecting 00:03 to 3:10 of the chapter (out of the 7 minutes). It seems Handbrake can't do it for 480p... and if using AutoGK and then VirtualDub to resize and do video time selection, it feels so old school (autogk not updated since 2005)... Windows Movie Maker seems like 15fps video quality... Is there a way to do it nicely? Details if using Handbrake: I can't find a way to convert a DVD recorded video which is 720 x 480 (Wii Gameplay in 16 : 9 ratio) into 852 x 480... It seems that the only possible resize is to shrink but not to expand? It is fine to make it 720 x 406... except YouTube won't be able to show it as 480p... If it can be made 852 x 480, then YouTube can at least show it as 480p (besides 360p and 240p)... is there any way to do it? thanks.

• Having issues with flickering output to TV from Windows 7 laptop

  - by Nimmy Lebby

  I cannot tell why this is happening. I cannot get a pattern as to when it happens. Sometimes, I watch entire Hulu content without any interruptions. Other times, it happens 2-3 times in a span of 3 minutes. Then it stops for 10-15 minutes. Lenovo T410s Integrated graphics: Intel HD Graphics (Driver=8.15.10.2253, Video BIOS=2026.1) TV is a Zenith (does not happen with other laptop so doubt it's TV) TV connected to laptop using HDMI-to-DVI cable (previously was connected directly via DVI but I bought a new cable and it's still happening) Anyone could help me troubleshoot this? I'd greatly appreciate it. If you need more information, I'll be glad to provide it.

• Windows lowers volume because of "communication"

  - by SnippetSpace

  Randomly, or at system sound (usb connect for example) Windows 8 lowers the volume of all other sources. (Same problem can exist on windows 7, just look online). This is happening because of the "communication detection" made to detect phone calls and then lower volume. But in my case it happens all the time without reason as if windows always considers myself in a call. Do any of you have the same problem? is this a driver issue or a windows issue? I know this has been posted many times but they usually just tell you to turn off the setting above. I'm looking for an explanation or a solution :). Thanks for your feedback and ideas.

• Do I need liquid cooling?

  - by Mrrvomun

  I'm building a computer mainly for gaming and developing games. It's going to be a three screen system with two GeForce GTX 460's and a quad-core i7. The newegg wattage calculator says I need around 900W. The case I intend to get is this one. Full specs if you need 'em are at the end of this post. I have no intentions to overclock the system at the moment, but this may change in the future. I've done a lot of research on the subject, and the answers I've found indicate that it takes a heck of a lot of power to require liquid cooling, and most non-overclocked systems don't need it. But I haven't seen a question about a system with two GPU's, so I ask you the following two questions: Assuming that the system is used for gaming for very extended periods of time (say 4-6 hours at a time, nonstop) with all three screens running at full 1080p, would the fans installed in the system suffice? Or would I need more fans and/or liquid cooling? If the system is used under the same circumstances as above, and is overclocked to a reasonable level, would the fans installed in the system suffice? Or would I need more fans and/or liquid cooling? Specs: Intel Core i7 16GB DDR3 Two nVIDIA GeForce GTX 460 3TB HDD Two DVD-RW writers Thermaltake 1050W power supply Case is linked above

• Ubuntu and Belkin N150 f6d4050 Wireless USB adapter v2

  - by Andrew

  I'm new to Ubuntu, and I'm trying to get my Belkin USB adapter to work. There are plenty of discussions out there already about this, but none really helped me out. Here's what I've done - Installed ndiswrapper Installed ndisgtk Installed the driver (rt2870.inf) via ndisgtk ndisgtk reported that the driver was installed and the hardware was present. The green light on the adapter is solid green, which I assume means that Ubuntu is aware of it's presence. However, when I click the little wireless symbol at the navigation bar, there's no option to choose my adapter (assuming that it's supposed to show up there...) My adapter version is F6D4050 - Where do I go from here? I'm a Ubuntu newb, so speak slowly. :P lsusb - andrew@ubuntu:~$ lsusb Bus 002 Device 003: ID 046d:c517 Logitech, Inc.

• Setting up a wireless connection

  I've got a DLINK router connected to my ADSL modem that forms the hub of my home network. I've two clients - A desktop with an onboard wireless adaptor and a laptop that's outfitted with the same. The former runs Windows 7 x64, the latter Windows XP x86. I'd like to setup a wireless connection between the two that would allow me play games over to and to a lesser extent, transfer and stream data. How would I go about doing it ?

• Windows 7 boot problem (with colorful blinking smilies)

  - by Ishmael Smyrnow

  I put my computer (Windows 7) to sleep, and a couple hours later, tried to wake it back up, but the monitor wouldn't come back on. I did a hard reset (held power button), but I still couldn't get the monitor to show anything. I plugged it into my laptop, and the monitor works fine. I then swapped out the video card with an older one I have. The monitor came on and started showing the boot process. However, shortly after the Windows 7 animated logo came up, the screen went blank, it made this weird beeping noise, and I seen the strangest thing ever. Small, colorful blocks started to fill my screen, and flash, as if something was loading. Inside of those blocks, were smilies (like the ASCII character kind). This continued for about a minute, then the computer rebooted. It scared the sh!t out of me. I've never had a virus before, and I'm savvy enough to keep myself from one, but I'm wondering if that's what it was. I've been using computers for ages, and never seen anything quite like this. Has anyone ever seen something like this? I'm doing hardware diagnostics before trying to boot into Windows again. Hopefully I can figure this out, but I thought I would consult the SU community while I wait on these results. -- UPDATE -- I did a Memory Diagnostic, which turned up nothing. I also booted into Safe Mode no problem, and scheduled a disk check on both of my drives (I dual boot XP & 7). I was feeling good, and tried putting my regular video card back in, and the monitor won't display anything with it. Also, even though the monitor displays nothing, the system sounds like it's booting up. However, I hear a clicking in one of my hard drives that isn't there with the older video card. Could this be a problem with my hard drive, video card, or PSU? PSU makes sense, except for the fact I've been using the same setup for over a year, and the video card doesn't require it's own power plug thing.

• Command line tool to query HTML elements (linux)

  - by ipsec

  I am looking for a (linux) command line tool to parse HTML files and extract some elements, ideally with some XPath-like syntax. I have the following requirements: It must be able to parse arbitrary HTML files (which may contain errors) in a robust manner It must be able to extract text of elements and attributes What I have tried so far: xmlstarlet: would be perfect, but mostly reports errors in files (e.g. entity not defined), even xml fo or htmltidy does not help. xmllint: the best I have found so far, but is not able to extract attribute texts. Something like //a/@href reports <a href="foo">, what I need is just foo. string(//a/@href) works, but queries only the first entry. data is not supported. hxextract: works, but cannot extract attributes. XQilla: would support XPath 2.0 and thus data. It also support xqilla:parse-html, but I have had no luck making this work. Can you recommend me another tool?

• Linux Ubuntu: Updating the GRUB menu

  - by Mr X

  So apparently there are 2 versions of Linux on my laptop(I have a dual boot system with Linux and Windows 8 but Linux is the master OS). One of them uses the Kernel version 3.11.0 whose headers + source code are incompatible with my wireless driver. My laptop is a Toshiba Satellite with a Realtek RTL8188CE wireless lan.So the newer kernel version is still the first option on the menu and to get to Linux I use the "Previous versions of linux" which is running Kernel version 3.2.0-55. What can I do to update the grub menu so that Linux version with the 3.2.0-55 Kernel appears as the primary option? Do I need to get rid of/uninstall the newer kernel version? How can I do this without screwing up Linux entirely?

• Is there a way to change the GTK theme for applications run as superuser on KDE?

  - by Patches

  When I run GTK applications on KDE, they use the QtCurve theme that matches my color and font scheme as configured in the KDE System Settings application. However GTK applications run as superuser use the old default GNOME, regardless of whether I run them with kdesudo, gksudo, or sudo on a terminal. For example, here's gedit run as superuser on top, and under my normal user account on the bottom: Strangely, KDE applications run with kdesudo display the default Oxygen styling but use my settings when run with sudo on a terminal. Is there any way to configure the stying GTK applications use when run as superuser on KDE?

• How to recover bitlocker encrypted partition that is now 'unallocated'/'free space'?

  - by Atishay Jain

  My hard drive had 5 partitions(including 1(some 4-5GB) bit locker encrypted one). When I used disk mgmt I could view 2 partitions(24.4GB and 8.94GB) in green colour labeled Empty space. So, I wanted to merge them and I used minitool partition wizard for the purpose. I don't know, what that software did, but all I was left with 2 partitions and lots of green free space. I recovered 2 partitions using EaseUS partition master, but the bitlocker encrypted partition cannot be searched by it(and also minitool partition recovery). Now, the disk mgmt shows 2 free space partitions of 28.36GB and 8.94GB respectively. Here is a screenshot http://s14.postimage.org/4tvij041t/Screen_Shot003.jpg Please, tell me a way to recover the bitlocker encrypted partition that is showing as a free space in disk management. P.S. - It contains very important data.
