• How to know my wireless card has injection enabled?

  - by shrimpy

  I am playing around with aircrack. And was trying to see whether my wireless card on my laptop can pass the injection test And I end up seeing the following... does it mean my wireless card is not able to run aircrack? root@myubuntu:/home/myubuntu# iwconfig lo no wireless extensions. eth0 no wireless extensions. eth1 IEEE 802.11bg ESSID:"" Nickname:"" Mode:Managed Frequency:2.437 GHz Access Point: Not-Associated Bit Rate:54 Mb/s Tx-Power:24 dBm Retry min limit:7 RTS thr:off Fragment thr:off Power Management:off Link Quality=5/5 Signal level=0 dBm Noise level=-57 dBm Rx invalid nwid:0 Rx invalid crypt:781 Rx invalid frag:0 Tx excessive retries:0 Invalid misc:0 Missed beacon:0 root@myubuntu:/home/myubuntu# aireplay-ng -9 eth1 ioctl(SIOCSIWMODE) failed: Invalid argument ARP linktype is set to 1 (Ethernet) - expected ARPHRD_IEEE80211, ARPHRD_IEEE80211_FULL or ARPHRD_IEEE80211_PRISM instead.

• The sound freezes while listening to music

  - by Scott

  I have bought an sound card - Sound Blaster X-FI Surround 5.1 PRO and while I'm listening to the music, after few minutes or even hours (it does happends randomly) the sound dissapears and I have to go settings: Playing Devices - Advanced and switch the Default Format (sampling frequency) and switch from the `16-bits, 48000 Hz (DVD Quality) to any other from the list (16-bits, 96000 Hz or 24-bits, 48000 Hz or 24-bits 96000 Hz). I have been trying to set all of the above options, but for all of them the sound freezes after listening to music. It is getting annoying and I hope its the settings fault and not my sound card. I got my drivers installed from the attached CD and I'm running Windows 7 HP 64 bits. If anyone would try to help me, I would really appreciate this.

• video editing tool to color overlay a specific part

  - by Santosh

  I have downloaded a video from YouTube. But the uploader has put some link (their twitter and facebook) for promotional purpose. The links keeps coming up through out the video in the black area (up and down of the video which are black). Thank god that links are on the black part of the video otherwise it would be hard to remove.    Also I want to remove the the last few seconds of the video. I don't want to crop that part. The video is in MP4 format. I don't want to lose the quality in anyway, I won't mind if the file size increases. I want a opensource and free tool. Good if it is available to both Windows and Ubuntu. Here is a link to the video.

• better options for screen?

  - by lonestar21

  OK. So I love screen. It has saved my bacon a few times when machines crash or get disconnected from the network. However, there are enough reasons keep keep me from using screen for everything, which include: Pain in the butt scrolling. Why can't I just interact as though this is a normal bash shell? My keyboard shortcuts are gone. I have a number of things customized in my bash environment, is there a way to get them to work in screen as well? Are there any tools our tips that I can use to make my screen-using experience as high quality as my bash using experience?

• How to download a URL as a file?

  - by Michelle

  A website URL has "hidden" some MP3 files by embedding them as Shockwave files, as follows. <span class="caption"><!-- Odeo player --><embed src="http://odeo.com/flash/audio_player_tiny_gray.swf"quality="high" name="audio_player_tiny_gray" align="middle" allowScriptAccess="always" wmode="transparent" type="application/x-shockwave-flash" flashvars="valid_sample_rate=true external_url=http://podcast.cbc.ca/mp3/sundayeditionstream_20081125_9524.mp3" pluginspage="http://www.macromedia.com/go/getflashplayer"></embed></span> How can I download the files for off-line listening? I've found two methods: 1. The Stack Overflow Method Create a new local HTML file with just the links, for example: <a href="http://podcast.cbc.ca/mp3/sundayeditionstream_20081125_9524.mp3">Sunday Edition 25Nov2008</a> Open the file in the browser, right click the link and File Save Link As. 2. The Super User Method Install the Firefox addin Iget. (Be sure to use the right version for your Firefox version.) Tools Downloads Enter URL in the field. Are there any other ways?

• ImageMagick convert to png32, can't change background at all

  - by Doug

  So I'm stumped. I've been wrestling with this simple command to turn an SVG file into a transparent SVG to no avail. Here's my command convert svg:/home/media/svgTest.svg -quality 100 -background none -size 3300x3300 png32:/home/media/pngTest.png The PNG comes out fine, but the background is white. Upon further investigation - the PNG's background is white no matter what I set the -background option to. I've tried black, tomato4, and even various hex colors. Nothing - just white. My SVG has no background fill layer or anything like that, it's just a couple of blue path layers. Also, I am running ImageMagick v 6.6.9-7 on Ubuntu 12.04 Lts What am I doing wrong? Thanks

• Linux: how to "zoom" into a screen area à la Mac OS X?

  - by puccio

  It seems to me on Mac OS X it is possible to "zoom" (like a photocamera does) into a region of the screen. It is handy for example to put at full monitor size a video which would otherwise be limited to be just into a small window (ie. embedded in a web page and not watchable standalone.), obviously losing some quality due to the "zoom". Do you know of any tool or way to do the same thing on a Linux desktop (with Gnome as desktop manager if it is desktop manager dependant). Thanks in advance for any suggestion.

• Workstation Build: Single 2.66ghz i-7 with overclock potential, OR Dual 5520 2.26ghz Xeons?

  - by jdc0589

  There are probably better places to ask this, but I am used to the excellent quality of responses on stack overflow. I am rebuilding my desktop in a few months. Aside from normal lightweight internet usage, I use it to run sqlServer, mySql, 1-2 Ubuntu VMs from time to time, lots of IDE's, and a media server for my PS3. The two possible setups cost the exact same amount (within $50) and would both have 12gb 1333mhz ddr3 ram and a 500gb RAID-0 array (250x2). Now, If I go with a single i-7 920 2.66ghz quadcore, I can easily overclock it to 3ghz, and would have cash leftover to get a 160gb ssd (either the ocz vertex or the 120gb intel) for the main OS/Program install drive. Else, I could get a dual lga1366 motherboard with two e5520 Xeon's (2.26ghz),just use the disks I already have. So, do I go for 8 physical/16 virtual cores at 2.26ghz (No overclocking on server boards) with normal disk I/O, or a 4 physical/8 virtual cores at 3.0ghz with really outstanding disk I/O?

• Best way to "stream" music / video to my HDTV from my pc?

  - by loj

  My requirement is simple: I have a laptop and a desktop at home that I often use for various media (music, videos etc.) and I want to know what the best (quickest, most seamless, best quality etc) solution for sending this media to my HDTV (and connected sound system). An example would be I'm listening to some music from youtube on my laptop in my living room and want to quickly send it to my tv (which has a sound system) so that I don't have to listen to it through my laptop. I mainly use linux (but a windows dependent solution would be ok too if its the best option). I would greatly appreciate any suggestions. Oh and a wireless solution would be best.

• Bulk Deleting All Messages in a Folder in Microsoft Outlook Web Access [closed]

  - by Cerin

  Possible Duplicate: Multiple delete in Microsoft Outlook Web Access How do you delete all messages in a folder in Outlook, preferrably through Web Access? I left my Outlook account unattended for several days (on vacation) and when I got back I found several folders with over 5k emails, mostly error logging or spam. When I try to open the Outlook client, it just locks up, presumably unable to download that many emails. I can view at most 100 emails at a time, but I can't select all emails to delete or permanently delete them immediately, so manually deleting this many emails is going to take a while. Gmail has a similar feature to select and delete all emails in a folder, and that's free so I figure being a quality non-free product from Microsoft, Outlook should have a similar feature (yes that's sarcasm). I've Googled, but I'm not finding anything. Is this possible?

• Is 50% download speed on a wireless G network normal?

  - by Bartlomiej Skwira

  I have a wired connection of about 36Mb/s, but my wireless speed is max at about 18-19Mb/s. I have a WRT54G-TM (T-Mobile, 802.11G) router with DD-WRT firmware - I've upgraded it to latest build. Done some settings changes: changed channel - 13 wireless network mode - G-only ACK Timing - 0 Fragmentation Threshold and RTS Threshold - 2304 Basic Rate - All Signal/Noise ratio: -46/-94, signal quality ~50-60%. Is this normal with G networks? Edit: The AP is located about 2 meters from laptop, no walls or metal objects, but its next to a TV. I've done a channel scan (had problems locating it, go to "Status - Wireless - Site survey" - lame naming) and everybody else is on channels 1 and 6. Switched to channel 11 but it didn't help. As for trasmit power I got best results with default 71mw. The antenna might be a factor, I'm using the default 2 antennas.

• How to play multiple videos side-by-side synchronized?

  - by Don Salva

  I've got 3 videos, all 3 have the same time, same amount of frames, and they only differ in terms of encoding quality. Now I need them to run side-by-side in synchronized fashion for evaluation purposes. Meaning when I press "play" BOTH! videos should start. Analogically for stop, forward, backward. Anyone know any player capable of doing that? By that I mean playing more than 1 video side-by-side... Platform: Win7

• Domain Hosting, DNS/NS Management [closed]

  - by ledy

  What criteria do you have for choosing the right provider for registering a domain? (not hosting, only the domain) So far, I can only see the different pricing and features of the DNS manager but have no idea what I have to pay attention in addition to this. How to know about the quality of the provider's nameserver and could there be differences in speed concerns. Background: The hosting itself incl. webspace, server etc. is separate from the domain and I am not going to book the domain with the same hoster as the webspace/server hoster.

• Skype audio always goes 'robotic' for the same user

  - by John

  Someone I talk to on Skype a lot has a very persistent issue, where after a few minutes their voice goes very 'robotic'... still understandable but annoying. We can restart the call and it's fine, but fairly consistently after a few minutes it returns. He experiences this with other people too, not just me - I don't have anyone report problems with my audio quality. This is not an ISP issue - he gets the same problem on multiple PCs in different countries, in fact he's even recently moved to a different continent and got a new internet connection... same problem. It seems somehow to be a problem with his Skype account, which is really quite odd. It's been going on for months of not longer.

• Blank screen on laptop after replacement

  - by Mark

  I have an Acer Aspire 5332 laptop, running Windows 7 home premium 32bit. My screen broke, but the particular screen (LED) are no longer made so I bought a CCFL one with a new converter which has proven to be compatible according to the supplier. When I first booted the screen went blank just after the Windows logo was displayed. I suspected a driver issue, so booted in safe mode without any problems, disabled the display adapter (Intel 4 series express family) and it booted up fine. So I guess the screen is not compatible with the display adapter. The driver version is 8.15.10.1892. I tried updating from the Intel site, but it saying it cannot (something to do with manufacturer specific). The supplier is not willing to take it back, so I'm down £60 (UK). I can use it with the adapter disabled, but the quality is bad and I cannnot play video, etc. Any help appreciated.

• Which handsets work with IP DECT base?

  - by waldrumpus

  My workplace uses an Ascom IP DECT base station (IPBS1), and Ascom handsets as well. We're looking to replace some broken handsets; the ones by Ascom, however, are rather expensive, and we're not altogether satisfied with their quality. I've been looking at handsets from other manufacturers, which are much less expensive - however, since I don't know anything about DECT, VOIP, etc, I don't know if they will work with the base. I've perused the base's manual, but found nothing on handset compatibility. How can I find out what kind of handset works with our base?

• Shortcut with arguments in Debian

  - by Duncan

  I have a volume on a debian server which contains a large number of images at full resolution in various folders. What I'd like to do is have a separate sort of browse proxy folder which contains lower quality browse copies of these to enable users to access them for viewing over lower speed dial in accounts. I'd ideally like these to be created on the fly using ImageMagick so there isnt the need to store the large number of browse copies full time and worry about keeping them up to date etc The way I'd invisaged this happening is the browse proxy folder containing a duplicate file and folder structure but with symlinks pointing to a script to transform them with the file path as an argument. Except I know this isnt possible with symlinks so am wondering if there's another way of doing this on linux. On windows shortcuts can take arguments and I'm wondering how to do the same on a Linux platform? (or perhaps I'm going about this the wrong way?)

• Windows VPS/Cloud Host Recommendations?

  - by user18937

  As Hosting.com are no longer offerring Windows VPS accounts, we are looking for a new US based provider. Looking for something that offers standard Windows IIS hosting for a Dotnetnuke portal site with SQL Server Express or Web. Basic managed services for OS updates as well as regular backups required. Good level of support and solid uptime is critical. Budget in the $150-$200 month range but flexible depeding on quality and services offerred. Anyone have any suggestions and good feedback they can share? Currently looking at Jodohost as an option but would like some other possibilities as their support can be suspect at times we have found. A cloud solution in same range would also be an option.

• Can I use my old Sony Handycam TRV815 as a web cam?

  - by Optimal Solutions

  Has anyone ever used their old Sony Handycam (or maybe any older hand-held camcorder) as a web cam? As in streaming the live video from the cam to a web server (local or remote/Internet). My TRV815 has a pretty darn good picture quality for its time.. Via USB or Ethernet. It has S-Video but I think that is input. It has RCA out (white/red for audio and yellow for video) and I have used that to display to my TV. I have web cams already but was wondering if I could put this one to use also just for kicks..

• Writing good looking documentation in pdf format on a mac [closed]

  - by Matthew

  I'd like to write some documentation that will be written in sections (1.1, 1.2, 2.1, 2.2, 2.3, etc). I'd like to use something that will generate the table of contents in the end or at least have it "linked" up so that when I make changes everything is still accurate (if I merge section 2.1 and 2.2 or something). The end result needs to be in pdf. I don't want to pay $350 for Acrobat Pro either... I've got microsoft word, but every little thing is a pain (for example, having one background of a page be a different color than another). Any ideas on how to create quality documentation in a pdf format?

• Some printers are merged into control panel on Windows 7

  - by Bertrand SCHITS

  I install the same printer several times to allow easy selection for users. They just choose the desired printer to have the corresponding functionnality (instead of going to printer properties and change them back and forth): one with double-sided printing, one for draft quality, one for upper tray, etc. On Windows 7, when I install a printer several times, the control panel's printers icons are merged. I then have only one icon for two or three identical printers. I can right-clic on the icon to display the usual menu, and some items of the menu have an arrow to access each printer. This is very missleading for users and admins. I have this behaviour on some computers, when others don't exhibit this. I didn't found what is the difference between computers with and without the problem. Anyone know how to prevent this ?

• Prevent history deletion on Google Chrome

  - by ProstheticHead

  One of the guys I'm in charge of hasn't been pulling his weight. His productivity and quality of workmanship are way down and his computer's been getting malware infections lately. You can see where this is going. I'm generally an easy going guy (and I don't want any trouble but I still have to address this issue). Is there a way to disable browser history deletion on Chrome? I'm hoping this alone will be enough of a deterrent to put things right.

  - by M. Cunille

  I have installed Ubuntu 12.10 in my computer with an Atheros AR5007 wireless card. I want to use Kismet but when I run it it starts displaying the message: ERROR: Packet source 'wlan0' failed to set channel X: mac80211_setchannel() It keeps displaying the same for every channel except channel 1.

I have installed the latest version of Kismet in the git repository and I even tried with the svn but it keeps displaying the same error.

• How to Install Mac OS X Lion on Your HP ProBook (or Compatible Laptop)

  - by Usman

  There’s nothing more satisfying than building a hackintosh, i.e. installing Mac OS X on a non-Apple machine. Although it isn’t as easy as it sounds, but the end result is worth the effort. Building a PC with specific components and installing Mac OS X on it can save you thousands of dollars you might spend on a real Mac. And now, it’s time to step into the portable world. Today we will show how you can turn an HP ProBook (or any compatible Sandy Bridge laptop) into a 95% MacBook Pro! Why should (or shouldn’t) you do it? Let’s clarify whether or not it should be done. Firstly, we all know Apple makes awesome laptops. The design, build quality, and the aesthetics (not to mention, the glowing Apple) would make you crave for one. Secondly, all these Apple laptops are bundled with Mac OS X, which (for some people) is the most user-friendly and annoyance-free operating system. Digital artists, musicians, video editors, they all prefer Mac for a reason. So the verdict is, if hardware design is what you really look for, you should get a real Mac, and we are not at all stopping you from doing so. But if you’re only concerned with the OS (and saving a few bucks in your pocket), you may consider giving this a shot. But remember, it may not perform as good as a real Mac does. The results vary, so hope for the best, and proceed with caution. Why HP ProBook?
