• MPlayer does not work

  - by Soham Pal

  Using the xubuntu desktop, on Ubuntu Raring updated from Quantal. MPlayer never really worked. No video, no audio, nothing.

• SQL Syntax to count unique users completing a task

  - by Belliez

  I have the following code which shows me what users has completed ticket and this lists each user and the date they close a ticket. i.e. Paul Matt Matt Bob Matt Paul Matt Matt At the moment I manually count each user myself to see their totals for the day. EDIT: Changed output as columns instead of rows: What I have been trying to do is get SQL Server to do this for me i.e. the final result to look like: Paul | 2 Matt | 5 Bob | 1 My code I am currently using is and I would be greatful if someone can help me change this so I can get it outputting something similar to above? DECLARE @StartDate DateTime; DECLARE @EndDate DateTime; -- Date format: YYYY-MM-DD SET @StartDate = '2013-11-06 00:00:00' SET @EndDate = GETDATE() -- Today SELECT (select Username from Membership where UserId = Ticket.CompletedBy) as TicketStatusChangedBy FROM Ticket INNER JOIN TicketStatus ON Ticket.TicketStatusID = TicketStatus.TicketStatusID INNER JOIN Membership ON Ticket.CheckedInBy = Membership.UserId WHERE TicketStatus.TicketStatusName = 'Completed' and Ticket.ClosedDate >= @StartDate --(GETDATE() - 1) and Ticket.ClosedDate <= @EndDate --(GETDATE()-0) ORDER BY Ticket.CompletedBy ASC, Ticket.ClosedDate ASC Thank you for your help and time.

• Introducing Ben Barreth, Community Builder &amp; Software Developer at GWB

  - by Staff of Geeks

  Please extend a warm welcome to Ben Barreth as the new community builder and full-time software developer at Geeks With Blogs. We've been wanting to add some cool features to the site but haven't had the opportunity until now. Adding Ben to the team should give us a big kick in the right direction. Ben has several years of .Net development experience and is heavily involved in the startup community in Kansas City, including the KC Startup Village as well as his own startup initiatives: Homes for Hackers and FreeIdeas.co. He loves working with people even more than coding and is excited to serve the GWB community in any way possible. Ben originally met Matt Watson as a beta tester for Stackify, the software company that gives developers the safe & secure access to troubleshoot in production. Jeff Julian and Matt are old friends and recently decided the site needed new ownership to carry it forward and build the enhancements it deserves. The site management transferred in October and Matt quickly began looking for a full-time community builder to lead the charge. Ben bumped into Matt once again at a Tech Cocktail event at the Boulevard Brewery where Stackify was presenting and an alliance was forged. Yes, the beer really IS that good! Which brings us to the biggest question of all: Where do you want Geeks with Blogs to go next? As a contributor to the GWB community, now is your chance to be heard! What are we missing? Features on our radar: New templates Add a code "formatter" to posts Add categories to blog feeds Re-skin the site and redesign the logo Feel free to contact Ben with further questions and ideas below. We need your help! @BenBarreth [email protected] Cell: 816-332-9770 www.linkedin.com/in/benbarreth

• Social Engineering approach to collecting from deadbeat ebay winners

  - by Malcolm Anderson

  You just sold something on e-bay and now the winner won't pay up.  What do you do?  I'm not sure what the legality of this kind of Social Engineering hack is, but I believe you've got to give it points for elegance.   Here's the link to the lifehacker.com post (I can't find the original Reddit post.) Reddit user "BadgerMatt" (we'll call him Matt for short) recently posted a story about how he tried to sell tickets to a sporting event on eBay, but when the auction was won the winning bidder backed out of the deal. In some cases this is mainly an inconvenience and you can re-list the item, but Matt was selling tickets to a sporting event and no longer had the time to do that. With the losing bidders uninterested in the tickets, he was going to end up stuck with tickets he couldn't use and a deadbeat bidder who was unwilling to honor their contract. Rather than give up, Matt decided to trick her into paying: I created a new eBay account, "Payback" we'll call it, and sent her a message: "Hi there, I noticed you won an auction for 4 [sporting event] tickets. I meant to bid on these but couldn't get to a computer. I wanted to take my son and dad and would be willing to give you $1,000 for the tickets. I imagine that you've already made plans to attend, but I figured it was worth a shot." The woman agreed, but for $1,100. She paid for the auction, received the tickets, and then Matt (of course) never re-purchased them. Needless to say, the woman was angry. Perhaps it was the wrong thing for the right reasons, but I'm mostly jealous I never thought of it back when I still sold things on eBay.

• How Can I Improve This Card-Game AI?

  - by James Burgess

  Let me get this out there before anything else: this is a learning exercise for me. I am not a game developer by trade or hobby (at least, not seriously) and am purely delving into some AI- and 3D-related topics to broaden my horizons a bit. As part of the learning experience, I thought I'd have a go at developing a basic card game AI. I selected Pit as the card game I was going to attempt to emulate (specifically, the 'bull and bear' variation of the game as mentioned in the link above). Unfortunately, the rule-set that I'm used to playing with (an older version of the game) isn't described. The basics of it are: The number of commodities played with is equal to the number of players. The bull and bear cards are included. All but two players receive 8 cards, two receive 9 cards. A player can win the round with 7 + bull, 8, or 8 + bull (receiving double points). The bear is a penalty card. You can trade up to a maximum of 4 cards at a time. They must all be of the same type, but can optionally include the bull or bear (so, you could trade A, A, A, Bull - but not A, B, A, Bull). For those who have played the card game, it will probably have been as obvious to you as it was to me that given the nature of the game, gameplay would seem to resemble a greedy algorithm. With this in mind, I thought it might simplify my AI experience somewhat. So, here's what I've come up with for a basic AI player to play Pit... and I'd really just like any form of suggestion (from improvements to reading materials) relating to it. Here it is in something vaguely pseudo-code-ish ;) While AI does not hold 7 similar + bull, 8 similar, or 8 similar + bull, do: 1. Establish 'target' hand, by seeing which card AI holds the most of. 2. Prepare to trade next-most-numerous card type in a trade (max. held, or 4, whichever is fewer) 3. If holding the bear, add to (if trading <=3 cards) or replace in (if trading 4 cards) hand. 4. Offer cards for trade. 5. If cards are accepted for trade within X turns, continue (clearing 'failed card types'). Otherwise: a. If only one card remains in the trade, go to #6. Otherwise: i. Remove one non-penalty card from the trade. ii. Return to #5. 6. Add card type to temporary list of failed card types. 7. Repeat from #2 (excluding 'failed card types'). I'm aware this is likely to be a sub-optimal way of solving the problem, but that's why I'm posting this question. Are there any AI- or algorithm-related concepts that I've missed and should be incorporating to make a better AI? Additionally, what are the flaws with my AI at present (I'm well aware it's probably far from complete)? Thanks in advance!

• In 'apt-cache depends' output, what is the meaning of Suggests, Recommends, |, <>?

  - by fred.bear

  I've checked the man/info page, but there is no reference to some aspects of the output fomat of apt-cache depends The man/info page tried to be helpful (in an obtuse manner); quote: "For the specific meaning of the remainder of the output it is best to consult the apt source code" Now in fairness to the info page, that quote was in regards to the 'showpkg' option which it had reasonably explained, but my option had no such explanation... I understand that Linux info comes from many sources (not just man/info pages), and I don't particularly want to rummage through the source (altough somtimes I do), so here is an example of what I'd like to know the meaning of. # I can assume what these mean, but... # What does | mean? (probably means 'or'???) # What does <pkg> and the following indentations mean? # At the end, the interaction(?) of Suggest and Recommends puzzles me. $ apt-cache depends solr-common solr-common Depends: debconf |Depends: openjdk-6-jre-headless |Depends: <java5-runtime-headless> default-jre-headless gcj-4.4-jre-headless gcj-jre-headless gij-4.3 openjdk-6-jre-headless Depends: <java6-runtime-headless> default-jre-headless openjdk-6-jre-headless Depends: libcommons-codec-java Depends: libcommons-csv-java Depends: libcommons-fileupload-java Depends: libcommons-httpclient-java Depends: libcommons-io-java Depends: libjaxp1.3-java Depends: libjetty-java Depends: liblucene2-java Depends: libservlet2.5-java Depends: libslf4j-java Depends: libxml-commons-external-java Suggests: libmysql-java |Recommends: solr-tomcat Recommends: solr-jetty

• Wireless driver - how to load manufacturer's STA file (Ralink 3290)

  - by Matt

  Caution: I'm a newb. Hardware: Giada i35G, cedar trail atom with nvidia gf119, railtek ethernet and Ralink 3290 for wireless. Already accomplished: Installed Ubuntu 12.10, loaded GPU drivers and redirected sound out through GPU card to HDMI. Ethernet works like a charm. Issue: Can't get my wireless up and running. There seems to be no package to which I can simply run a sudo get-aspt install ... I found the corresponding Linux driver from the manufacturer's site, but I have not managed to find out what to with the file. Here's the manufacturers site: http://www.ralinktech.com/en/04_support/support.php?sn=501 I get a file with the following name: \2012_0508_RT3290_Linux_STA_v2.6.0.0.bz2 I hope somebody might be able to tell me what to do next. Thanks for reading and apologies for potentially asking a trivial question. Best regards, Matt

• Installing Ubuntu on a computer with USB 3.0 hardware

  - by Matt

  I'm installing Ubuntu 10.10 32-bit version on an HP Envy 15. I get the same problem these people have here: "unable to find a medium containing a live file system" error when installing but the question was never resolved. I spent so long researching and got so frustrated that I took my computer down to a shop and asked them to install it for me. It took them a while but they managed to get it installed. The reason for this error they had said was because Ubuntu didn't have the USB 3.0 drivers it needed to install properly. I'm reinstalling Ubuntu yet again and I've run into the same issue so my question is: does anyone know.. a) Where to get these USB 3.0 drivers? b) How to get them installed when installing the Ubuntu OS? Thanks, Matt

• Are there any "traps" in cloning a VirtualBox VM for concurrent use on the same Host/LAN?

  - by fred.bear

  With Ubuntu as the Host, I want to run two similar/identical(?) instances of a VirtualBox Guest on the same Host, or perhaps on another Host which is on the same LAN... I have set up a Guest as a "base" for the two clones. I have exported it as an ovf appliance. I've imported this "base" guest OS back into VirtualBox, with a unique name and .vdk ... and I have started them both on the same Host, and all seems okay, but I do wonder if I have missed some significant point. ...eg. Is the virtual NIC the same? this would throw the LAN into confusion (I think)... and what about UUIDs? I haven't actually tried 2 clones together, yet... only the original and one clone, but I haven't gone beyond a simple startup ...

• How do the environments of a standard Terminal command-line and a bash script differ?

  - by fred.bear

  I know there is something different about the environment of the Terminal command-line and the environment in a bash script, but I don't know what that difference is... Here is the example which finally led me to ask this quesiton; it may flush out some of the differences. I am trying to strip leading '0's from a number, with this command. var="000123"; var="${var##+(0)}" ; echo $var When I run this command from the Terminal's command-line, I get: 123 However, when I run it from within a script, it doesn't work; I get: 000123 I'm using Ubuntu 10.04, and tried all the following with the sam results: GNOME Terminal 2.30.2 Konsole 2.4.5 #!/bin/bash #!/bin/sh What is causing this difference? Even if some upgrade will make it work in scripts... I am trying to find out the what and why, so in future, I'll know what to look out for .

• Is there a IRC Client which can use or emulate mIRC scripts

  - by fred.bear

  I've used mIRC (Windows) for years, and have some custom scripts, written in mIRC's own scripting language. Is there an Ubuntu/Linux IRC Client which will allow me to use my scripts as-is? Failing that, is there a "functions a lot like mIRC" Client available? I've just tried Pidgin's IRC client, but it seems to be quite basic. I couldn't see any way for it to tap into channel activity via scripts. I don't want to use Wine... WineHQ reports it as having too many bugs for my liking, and anyhow, I try to avoid using Wine like I do Windows :)

• Is the difference between sudo and gksu the same as the difference between sudo -i and sudo -s?

  - by fred.bear

  Is the difference between sudo cmd and gksu cmd, the same as the difference between starting a shell with sudo -i and sudo -s? ... or put another way, Is sudo cmd the same as sudo -i cmd and gksu cmd the same as sudo -s cmd? EDIT: Based on what I read on an Ubuntu Documentation Page where it says: You should never use normal sudo to start graphical applications as root. You should use gksudo (kdesudo on Kubuntu) to run such programs. gksudo sets HOME=~root, and copies .Xauthority to a tmp directory. This prevents files in your home directory becoming owned by root. (AFAICT, this is all that's special about the environment of the started process with gksudo vs. sudo). The "AFAICT" doen't really give me full confidence that there is nothing more to it. (..a belated UPDATE: I tested his commemnt today (2 months later) about: "This prevents files in your home directory becoming owned by root." All files I created via sudo/gksu were all owned by "root", and the group was "root".) I've read parts of the info sudo and noticed the -i and -s seem to be doing the same thing as the AFAICT environment issue... but I hit overload.. so I've asked my question here. PS.. My question is not about sudo vs gksu .. It is more about: Is gksu the same as sudo -s .. and if not, how do they differ?

• What causes Nautilus to restart whenever I kill it?

  - by fred.bear

  In htop, I kill Nautilus, and within one second, it's back, with a new PID! The restarted Nautilus shows in the Processes list, but has no GUI until I manually launch Nautilus... I've heard mention of Nautilus works in lockstep with the desktop... maybe that is the reason(?). Is there some sort of "watchdog" program keeping an eye on some distro-critical programs? Monitoring Nautilus doesn't seem like a Linux kernel issue, so I just wonder what is happening here?

• IBus client for GNU Emacs: Installed, but how do I start it?

  - by fred.bear

  Having recently moved to Linux/Ubuntu, I'm looking for a good editor, and GNU Emacs seems to fit the bill. One thing I want from a text editor is the ability to handle Unicode Input Method Editors in a "normal way", across the board. For Ubuntu, the "normal way" is via IBus. However, emacs does not support IBus "off the shelf". I found a launchpad project: IBus client for GNU Emacs: ibus-el. I've installed ibus-el and set it up as per the Customize section of this emacswiki IBusMode page. I included the suggested "toggle" keybinding: ;; Use s-SPC to toggle input status It seems to have installed okay, but I have no idea how to invoke IBus and switch IMEs. s-SPC doesn't fire up the IBus language panel... I'm stuck :( ...so close, yet so far.... Here are the startup *messages* Loading 00debian-vars... No /etc/mailname. Reverting to default...

• Is there a command-line utility app which can find a specific block of lines in a text file, and replace it?

  - by fred.bear

  UPDATE (see end of question) The text "search and replace" utility programs I've seen, seem to only search on a line-by-line basis... Is there a command-line tool which can locate one block of lines (in a text file), and replace it with another block of lines.? For example: Does the test file file contain this exact group of lines: 'Twas brillig, and the slithy toves Did gyre and gimble in the wabe: All mimsy were the borogoves, And the mome raths outgrabe. 'Beware the Jabberwock, my son! The jaws that bite, the claws that catch! Beware the Jubjub bird, and shun The frumious Bandersnatch!' I want this, so that I can replace multiple lines of text in a file and know I'm not overwriting the wrong lines. I would never replace "The Jabberwocky" (Lewis Carroll), but it makes a novel example :) UPDATE: ..(sub-update) My following comment about reasons when not use sed are only in the context of; don't push any tool too far beyond its design intent (I use sed quite often, and consider it to be invaluable.) I just now found an interesting web page about sed and when not to use it. So, because of all the sed answers, I"ll post the link.. it is part of the sed FAQ on sourceforge Also, I'm pretty sure there is some way diff can do the job of locating the block of text (once it's located, the replacement is quite straight foward; using head and tail) ... 'diff' dumps all the necessary data, but I haven't yet worked out how to filter it , ... (I'm still working on it)

• Need alternative to Accessibility's "Locate Pointer" to visually highlight the mouse.

  - by fred.bear

  Update: See end of quetion: A black-on-white cross-hair/I-bar mouse-pointer is soemtimes hard foe me to spot in amongst black-on-white text. I've tried "Accessibility / Mouse Accessibility / Locate Pointer" .. which will: Show pointer position when Control is presssed It works (to a point), but it does have a notable problem, which renders it inpractical. It has the uncanny side-effect of disallowing all Control key navigation while editing a file/dir name in Nautilus (F2).. Just touching the Control key drops it out of edit mode, which means I can't keyboard paste, move-L/R word etc... So, I'm looking for an alternative. I've tried Compiz's Water Effect, but I need something which is sharper, faster, and localized to the pointer. Compiz's Show Mouse (with fire) is no suitable. I'm really lookingf for an analog of "Accessibility / Locate Pointer": * ie. I hit Control (only).. and it blips a quick visual pulse. UPDATE: I've just realized why I can't find my mouse so often! ... It's because it is isn't there !!! ... Two apps I use a lot, Gedit and Konsole (KDE Terminal; it renders unicode better), ... dissolve the mouse-pointer to invisible after the first key is typed ... and Konsole does it after a few seconds of idle-time... like a video-player option: "hide the mouse".. Well I don't use the mouse much, and I thought it was juse my eyesight (which does rely a lot on Compiz's zoom)... I discovered it when I installed a "novelty" app, called Geyes from gnome-applets ("A goofy set of eyes for the GNOME panel. They follow your mouse.") ... It could follow the mouse better than me! :)

• Is there a command-line utility app which can locate a specific block of lines in a text file?

  - by fred.bear

  The text "search and replace" utility programs I've seen, seem to only search on a line-by-line basis... Is there a command-line tool which can locate one block of lines (in a text file), and replace it with another block of lines.? For example: Does the test file file contain this exact group of lines: 'Twas brillig, and the slithy toves Did gyre and gimble in the wabe: All mimsy were the borogoves, And the mome raths outgrabe. 'Beware the Jabberwock, my son! The jaws that bite, the claws that catch! Beware the Jubjub bird, and shun The frumious Bandersnatch!' I want this, so that I can replace multiple lines of text in a file and know I'm not overwriting the wrong lines. I would never replace "The Jabberwocky" (Lewis Carroll), but it makes a novel example :)

• How can I change the "timeout" duration for Nautilus "find the filename as you type" feature?

  - by fred.bear

  I often get stalled by the long timeout while typeing the first few letters of a file name in Nautilus... The current timeout seems to be 5 seconds. I'd prefer 1 second ...(as per item 2 on this page about Response Times) I don't use the mouse much, which means I either wait, or press Escape, when I don't find the file... I realize that this is a feature to some, but I'd rather not wait. Is there any way to change this timeout behaviour?
