  - by Mike C

  Looking forward to seeing all the DBAs, programmers and BI folks in Cleveland at SQLSaturday #60 tomorrow! I'll be presenting on (1) Intro to Spatial Data and (2) Build Your Own Search Engine in SQL. I've reworked the Spatial Data presentation based on feedback from previous SQLSaturday events and added more sample code. I also expanded the Build Your Own Search Engine code samples to demonstrate additional FILESTREAM functionality. See you all tomorrow! A little road music, please! http://www.youtube.com/watch?v=vU0JpyH1gC...(read more)

• Hibernate option doesn't appear in the shutdown menu(s)

  - by pileofrocks

  In 13.04, I enabled hibernation by following these instructions: You can also enable the hibernate option in the menus. To do that, use your favorite text editor to create /etc/polkit-1/localauthority/50-local.d/com.ubuntu.enable-hibernate.pkla. Add the following to the file and save: [Re-enable hibernate by default] Identity=unix-user:* Action=org.freedesktop.upower.hibernate ResultActive=yes It worked fine in 13.04, but after upgrading to 13.10, the "hibernate" option no longer appears in the top right corner shutdown/login menu and neither in the menu that comes up when I press the laptop's power button (image here). Yes, I have checked that the the .pkla file is still there untouched. What could be the problem? Hibernate itself still works when I do it from the terminal with pm-hibernate. Edit: similar question: Hibernation is still missing from menu in 13.10 after enabling via polkit. How to enable?

• Aide On a Low Memory System

  - by Jason Mock

  I have a Linux server running on a Linode.com VPS, where I'm trying to utilize aide to detect any issues. However, the nightly aide run uses up all of my available memory and swap (512MB RAM / 384MB SWAP). I've tried adding a script to /etc/cron.daily that would stop/start services using a lot of memory (apache2, mysql) during the aide run. Unfortunately, it seems like aide continued to use every available byte (including the space freed up from apache2 and mysql). Here's a graph from munin showing what happens when aide runs: Note the spike of memory usage, well into swap, when aide runs Any suggestions on tuning aide to not use so much memory, or is there an alternative to aide that doesn't behave this way?

  - by Kelly Cassidy

  It's been almost 4 years since I last logged into this site, but when I search my name I still rank high for people searching for me! I didn't realize I was so popular!Well, I've obviously since abandonded this blog and don't really want to maintain a blog in 2 locations now that I am getting back into it. (At least, not at this time - if I can figure out how to cross-post things may change...) I can instead be found at http://mindfulsanity.com where I have posted more frequently in the last few months on a few things web and other experiences and will continue to do so. I hope to do 2 posts per week, time permitting, and topic permitting. Enjoy!

• Is there an apt command to download a deb file to the current directory?

  - by Lekensteyn

  I am often interested in the installation triggers (postinst, postrm) or certain parts (/usr/share or /etc) of packages. Currently, I am running the next command to retrieve the source code: apt-get source [package-name] The downside is, this file is often much bigger than the binary package and does not reflect the installation tree. Right now, I am downloading the packages through http://packages.ubuntu.com/: Search for [package-name] Select the package Click on amd64/i386 for download Download the actual file This takes too long for me and as someone who really likes the shell, I would like to do something like the next (imaginary) command: apt-get get-deb-file [package-name] I could not find something like this in the apt-get manual page. The most close I found was the --download-only switch, but this puts the package in /var/cache/apt/archives (which requires root permissions) and not in the current directory.

• Azure Florida Association: Modern Architecture for Elastic Azure Applications

  - by Herve Roggero

  Join us on November 28th at 7PM, US Eastern Time, to hear Zachary Gramana talk about elastic scale on Windows Azure. REGISTER HERE: https://www3.gotomeeting.com/register/657038102 Description: Building horizontally scalable applications can be challenging. If you face the need to rapidly scale or adjust to high load variations, then you are left with little choice. Azure provides a fantastic platform for building elastic applications. Combined with recent advances in browser capabilities, some older architectural patterns have become relevant again. We will dust off one of them, the client-server architecture, and show how we can use its modern incarnation to bypass a class of problems normally encountered with distributed ASP.NET applications.

• MSM Merge Modules in Visual Studio 2013 [on hold]

  - by theGreenCabbage

  Could someone please let me know where I might find resources for creating MSM files? While I am able to create MSI files using InstallShield, it seems that Visual Studio no longer supports Merge Module Projects, judging by the link below and the screenshot of my version of Visual Studio 2013 - http://msdn.microsoft.com/en-us/library/z6z02ts5(v=vs.80).aspx To create a new merge module project: On the File menu, point to Add, then click New Project. In the resulting Add New Project dialog box, in the Project types pane, open the Other Project Types node and select Setup and Deployment Projects. In the Templates pane, choose Merge Module Project.

• Places to find free software projects who need developers/project managers?

  - by MHarrison

  While I have plenty of project management "booksmarts" and a handful of PM experience, I don't seem to have enough experience to get the sort of job I want. Since "I read another PM book/blog today" doesn't really count, I was thinking I could find some free/open source software (FOSS) projects who are looking for/hiring project managers or developers and see if there was anything I could volunteer for. Does anyone know of any FOSS employment sites where I might be able to find such projects? Something similar to careers.stackoverflow.com. I know I could just go to sourceforge/freshmeat and look around, but I was hoping to find some site that fills this need (and if any such sites exist, my google-fu is apparently VERY weak at finding them).

• Slow Wireless Reconnect After Suspend

  - by nrhine1

  I a Broadcom 4312 using the STA drivers, I reinstalled ubuntu because the b43 drivers were giving me a huge hassle along with some weird kernel issues. My wireless speed is fine, everything works well, except upon restart of computer and after taking the computer out of suspend. It takes about 30-45 seconds for the wireless to reconnect, and I think it is a driver issue (I clicked on the network manager at the top and for about 30 seconds there are no wireless networks listed.) I tried this advice already: http://lilserenity.wordpress.com/2007/10/31/fix-ubuntu-dropping-wireless-on-suspendhibernate-resume/ which basically says to change this: STOP_SERVICES="" to STOP_SERVICES="networking" in the file /etc/default/acpi-support This did not help anything. Something to note is that the issue does not occur when I am logging back in after already logging in once and logging out.

• Where does ntpdate get its settings from and what is the "no servers can be used" error about?

  - by wilhil

  When I run ntpdate on its own, I get the following output: 8 Jun 15:47:46 ntpdate[31251]: no servers can be used, exiting If I run it with the -q ntp.ubuntu.com switch, it seems to query just fine. I have been hunting through many files and the most relevant one I have found is /etc/default/ntpdate, however, even with NTPDATE_USE_CONF set to no, I just can't understand/see how this error is occurring Any ideas? Update-- been looking non stop... It appears that ntupdate-debianworks fine and is the actual command that makes use of /etc/default/ntupdate, but, this doesn't answer the main question and I still can't find it...

• Where can I train my game AI skills? (any upgoing competition?) [on hold]

  - by user1671710

  There are 2 main options - building AI plugin for existing game or entering to some competition. Do you have some concrete tips? Is there any competition which will be soon open? From my research, competitions: http://aichallenge.org (last 2011) http://www.battlecode.org (January 2014) http://webdocs.cs.ualberta.ca/~cdavid/starcraftaicomp/index.shtml (August 2014) http://aibirds.org (maybe summer 2014) http://www.marioai.org (last 2012) http://www.ice.ci.ritsumei.ac.jp/~ftgaic/index.htm (last 2013) http://www.pacman-vs-ghosts.net (last 2012) http://ai-contest2013.gameloft.com/index/contest (last 2013) http://www.botprize.org/ (last 2012) And maybe more. These are from quick research. Obviously there were many competitions this year but it is difficult to catch it. Main question is: Do you have any information of any currently running AI competition?

• Why does Ubuntu's webkit inspector look just like Safari?

  - by NoBugs

  In older Ubuntu, the python-webkit inspector looked like Chrome, as you can see in these screenshots: http://stackoverflow.com/questions/13132459 (It had some annoying bugs, too.) I see Midori's inspector also looks just like Safari, and still has some bugs. In the latest 14.04's python-webkit embedded browser, the inspector actually looks just like Safari - and also seems to still have bugs (icons missing, problems selecting). Is there a reason for this drastic change, or is it just a default configuration? Is there a recommended way to get the webkit-inspector fully working?

• Where can I find SPF record information for Network Solution hosted email?

  - by Steve Brown

  I have a client who has their e-mail hosted with Network Solutions and some of the e-mails they are sending are going to spam. I've searched Google for information on network solutions and SPF records but all the results have to do with "how to set up an SPF record" - which I understand how to do. The problem is that I can't find any information about what SPF records to use for network solutions hosted e-mail. I even tried lookup up spf records on networksolutions.com but it appears there are none. Where can I find SPF record information for Network Solution hosted email?

• Hidden Launch Bar wouldn't slide-out when moused over, now it won't hide away.

  - by Dave Keller

  When the launch bar is hidden, I have trouble getting it to slide out when I move the mouse pointer to the left side. After adjusting the settings under Settings--Appearance--Behavior, the bar no longer hides when a browser is open. Is there a fix for this. This all happened when I was looking for a way to change the icon sizes in the launch bar. Documentation from Linux.com told me to do it under Settings--Appearance, but there was no way to do it. Any help is appreciated! Thanks.

• Teaching java interfaces to absolute beginners: What is a good example? [closed]

  - by mrsteve

  Possible Duplicate: Explaining interfaces to beginning programmers? I searched on stackoverflow and here for a good example to teach java interfaces in a beginners class. I found the following post: http://stackoverflow.com/questions/416331/java-interfaces The Official Java-Tutorial and the references feature examples that are quite good but I would need a very simple example to start with for my class. I don't think the offical tutorial is the best resource for absolute beginners. The students are easily confused, and the most effective example would help. Any pointers or experience in teaching java interfaces?
