  • SQLSat65, Great Perf Counters Poster from Quest

    - by merrillaldrich
    I was fortunate to be able to attend the Vancouver BC SQLSaturday this past weekend, and it was excellent! Great sessions, good facility, well attended. Nice work, and a huge thank you to the volunteers that made that happen. One side perk: I got a copy of this terrific performance counters poster from Quest, which you can download as a PDF for free. Very handy, especially as a teaching tool. I'm using it for my SCOM MP work. Check it out....(read more)

  • VMware sharing folders between Win7 (host) and Ubuntu (guest)

    - by Pawel Goscicki
    What is the best way to share a folder between Win7 64bit (host) and Ubuntu 10.10 (guest) in VMware player? I can setup the sharing just fine (using vmware-tools), but all shared files are root:root owned with 777 permission set. Which, well, sucks. What can I do to have shared files with preserved ownership and permissions? I'm guessing I would need some kind of a file container, that would get mounted in Ubuntu as a block device (if so, it would need to be dynamic, i.e. expand with size of contained files). But maybe there is a better solution?

  • Solving 2D Collision Detection Issues with Relative Velocities

    - by Jengerer
    Imagine you have a situation where two objects are moving parallel to one-another and are both within range to collide with a static wall, like this: A common method used in dynamic collision detection is to loop through all objects in arbitrary order, solve for pair-wise collision detection using relative velocities, and then move the object to the nearest collision, if any. However, in this case, if the red object is checked first against the blue one, it would see that the relative velocity to the blue object is -20 m/s (and would thereby not collide this time frame). Then it would see that the red object would collide with the static wall, and the solution would be: And the red object passes through the blue one. So it appears to be a matter of choosing the right order in which you check collisions; but how can you determine which order is correct? How can this passing through of objects be avoided? Is ignoring relative velocity and considering every object as static during pair-wise checks a better idea for this reason?

  • How do I set up hosting a domain name at home with Apache?

    - by Andrew McIntyre
    I am relatively new to Ubuntu Linux and I am struggling to figure out the basic set-up of hosting a domain name at home with Apache2. I understand that you have to change your IP from dynamic to a static IP Address but I am not sure how you achieve that step. I am looking for some assistance on this on how to enable self signing certificates, make the domain name resolve on the Internet from hosting the website on the web server, enabling protected directories and the basic commands of accessing the directory where the website files can be uploaded and available on the World Wide Web.

  • Two "search" entries in resolv.conf

    - by Carsten
    I am using 12.04 and have a problem with my resolv.conf There are 2 search lines there. But I can only explain one.

    Possible Duplicate: Only ‘sdb’ shows up when installing 12.04 on a new Dell inspiron 14z I am new to Linux and trying to install Ubuntu 12.04 on a new HP Pavilion DV6TQE Ivy Bridge and being presented with the below screen which I believe is incorrect. My disk is set up as a basic disk (not dynamic) and I tried with a single C:\ partition and by creating a second partition in windows with no luck. Any ideas? UPDATE: I think I know what the problem is but I don't know how to fix it yet.. My hard drive has a 32gb mSSD cache which is listed as dev/sdb. for some reason this is causing the installation trouble.

  • HTTP 303 redirection and robots.txt

    - by Ian Dickinson
    On a site I'm working on, we're using the HTTP 303 redirect pattern (see this article for background) to distinguish between information and non-information resources. So: some URL's under /id get redirected to dynamically-created pages under /doc. These dynamic pages are built from a database, and contain links to other /doc/ resources, so in general we don't want them to be crawled. Our robots.txt contains: Disallow: /doc However, we do want the non-redirected pages under /id to get indexed by Google et al: Allow: /id So the question I have, which I can't find an answer to so far, is: if an allowed /id page 303-redirects to a /doc page, will it still be blocked by robots.txt? If yes, we're OK, but otherwise I'm going to disallow all /id resources in the robots file, as having the crawler hammer the db would be worse than losing search indexing for the /id pages.

  • How to set-up a simple subversion workflow

    - by Milen Bilyanov
    I am trying to set-up a simple SVN workflow at home. I am new to subversion (and programming) so I have been reading the official PDF documentations but still not sure about how to set-up my repository. I am working mainly with python, bash and rsl (Renderman Shading Language) So I already have a /dev structure on my disk as this: http://imageshack.us/f/708/devstructure.png/ And I have a /site structure that links to my /dev folder: http://imageshack.us/f/651/sitestructure.png/ So obviously starting to use SVN will change this approach that I already have in place. The question is when I am setting-up my SVN repository for the work I do in my /dev folder: Will I set-up a separate repository for each different programming platform? and Where exactly I should be placing my repository? Thanks.

  • Encourage the use of markup files as documentation in enterprise [closed]

    - by linquize
    To make it eaiser to do version control and diff files of documentation, use markup files, such as HTML: html/xhtml, XML: docbook, Wiki: markdown to replace doc/docx. docx is too complex and lengthy. For html, no extra document generation required. Programmers can write html directly and end users / managers can use any web browsers to view the document. For custom XML or Wiki formats, viewers are required to view the document or converters are used to export to pdf/doc. Is such move becoming popular in enterprise context? Why or why not?

  • Ad-Driven Apps Are Sucking Your Android Battery Dry

    - by Jason Fitzpatrick
    Ads in free Android apps might be annoying but you probably never imagined they were radically draining your battery. New research from Purdue University and Microsoft highlight just how much ad-driven apps tank your battery life. What did they find? That poorly designed ad-modules in free ad-driven applications are terrible at conserving energy. In popular applications like Angry Birds and Free Chess 70% of the energy the application consumed was used to drive the ads. They also surveyed other applications and found that ad-driven apps weren’t alone in excessive battery use–the New York Times app, for example, spent 15% of its battery consumption on tracking and background tasks.

    Some websites are not opening in my system. I am using Ubuntu 11.04. Earlier, when I was using Ubuntu 10.01, there was no such issue.

  • AdSense Custom Search Ads - custom quesry

    - by Alex
    i'm trying to set up a custom search ad, but I am nost sure about the query. On the site it says (https://developers.google.com/custom-search-ads/docs/implementation-guide) 'query' should be dynamic based on your page. This variable targets the ads and therefore should always match what the user on your site has just performed a search for. Now, what I understand is: I have to program my page so that the query variable contains some custom words. Am I right? If a user gets to my site through clicking on an adsense, there is no way to "know" what the user looked for and display my query accordingly, right? Thanks for any help!

  • What is the best way to find a python google app engine coach?

    - by David Haddad
    i'm a software engineer and have been building Google App Engine apps with Python for about a year. I have a pretty good familiarity with the main concepts: web app framework, modeling, queues, memcache, django templates, etc. Where I think I'm lacking is in methodology. Architecting the app, using git for versioning, designing an writing unit tests. I'm totally convinced to incorporate these practices in my development style, and have started reading up on them. However I've learned that I'm a much faster learner when I have someone experienced to ask questions to and interact with. IRC channels and forums like stack overflow are great. But sometimes you want something more dynamic that produces results faster. So my question is how can a person find an experienced engineer that is familiar with the technologies he uses and that is willing to give them a couple of hours of Skype coaching sessions per week in return for an hourly fee...

  • Google webmaster Verification failed.

    - by KMC
    I have a site created by Ruby on Rails. I had verified against Google Webmaster Tool some months ago, which was successful. One day webmaster starts giving me Re-verification fails. I tried again to verify my site using Meta tags and HTML files. But I kept having "Verification failed. The connection to your server timed out." Since then, Google stop crawling my site's content - though, somehow google still crawl my PDF contents on my site.

  • Memory Management/Embedded Management in C

    - by Sauron
    Im wondering if there is a set or a few good books/Tutorials/Etc.. that go into Memory Management/Allocation Specifically (or at least have a good dedicated section to it) when it comes to C. This is more for me learning Embedded and trying to keep Size down. I've read and Learned C fine, and the "standard" Learning books. However most of the books don't spend a huge amount of time (Understandably since C is pretty huge in general) going into the Finer details about whats going on Down Under. I saw a few on Amazon: http://www.amazon.com/C-Pointers-Dynamic-Memory-Management/dp/0471561525 http://www.amazon.com/Understanding-Pointers-C-Yashavant-Kanetkar/dp/8176563587/ref=pd_sim_b_1 (Not sure how relevant this would be) A specific Book for Embedded that has to do with this would be nice. But Code Samples or...Heck tutorials or anything about this topic would be helpful!

  • What's the best platform for blogging about coding? [closed]

    - by timday
    I'm toying with starting an occasional blog for posting odd bits of coding related stuff (mainly C++, probably). Are there any platforms which can be recommended as providing exceptionally good support (e.g syntax highlighting) for posting snippets of code ? (Or any to avoid because posting mono-spaced font blocks of text is a pain). Outcome: I accepted Josh K's answer because what I actually ended up doing was realizing I was more interested in articles than a blog style, getting back into LaTeX (after almost 20 years away from it), using the "listings" package for code, and pushing the HTML/PDF results to my ISP's static-hosting pages. (HTML generated using tex4ht). Kudos to the answers mentioning Wordpress, Tumblr and Jekyll; I spent some time looking into all of them.

  • Zookeeper naming service [closed]

    - by kolchanov
    I need a recommendation for naming service implementation. We are ISV and we have a lot of applications (services) with very different protocols such as http (Rest), low level tcp, amqp, diameter, telco protocols Rx, Ry, Ud and many others. We want to simplify configuration, deployment and service discovery procees and it seems that It's time to create central configuration registry. So I have few questions: - is zookeeper suitable for this purpose? - does exists more suitable and more special solution? - best practice for service naming for discoverin. Any standards? - recommendation for service configuration data structure Also we are keeping in mind future tasks For dynamic application distribution in a private cloud. Could you share your real life experience?

  • Inspection, code review - is it really testing?

    - by user970696
    ISTQB, Wikipedia or other sources classify verification acitivities (reviews etc.) as a static testing, yet other do not. If we can say that peer reviews and inspections are actually a kind of a testing, then a lot of standards do not make sense (consider e.g. ISO which say that validation is done by testing, while verification by checking of work products) - it should at least say dynamic testing for validation, shouldn't it? I am completing master thesis dealing with QA and I must admit that I have never seen worse and more ambiguous and contradicting literature than in this field :/ Do you think (and if so, why) that static testing is a good and justifiable term or should we stick to testing and static checks/analysis?

  • What's New & Cool in NetBeans IDE 7.x

    - by Geertjan
    Loads of new features have been added to NetBeans IDE during the NetBeans IDE 7.x release cycle, i.e., 7.0 together with all the minor releases that have come after that, up to 7.4, which was released during the last few days. Hard to keep track of everything added over all those releases, so instead of making a "What's New in NetBeans IDE 7.4" slide deck (which would only cover the highlights of the NetBeans IDE 7.4 Release Notes), as we would normally do, we've instead produced "What's New in NetBeans IDE 7.x", which is around 50 slides presenting all the key features of the IDE, together with all the key newest features. Here it is: If you want to present the wonderful world that is the NetBeans ecosystem to your JUG or school or university or colleagues in your company, just download the above slide deck (either PDF or the PowerPoint sources) here: https://netbeans.org/community/teams/evangelism And happy NetBeans IDE 7.4 to everyone using NetBeans IDE everywhere in the world!
