• dual boot, Sony Viao, all in one portable desktop, not working and crashes

  - by user287513

  I am a fan of Ubuntu but ever since I bought my new computers, both Sony Vaio, I can't get them running together with windows 8.1. When I try wubi, it doesn't show the install box, but some other information box. If I remove wubi from the iso and run it as admin on my desktop, it runs and installs but after rebooting, grub never comes up and it gives the error screen.. On my laptop, I had to make a usb install and partition everything myself and that worked for my laptop, for a little while. Windows boot loader would override and grub wouldn't come up no more, unless I try to boot from usb, with no usb in, and after it reboots because there is no usb, now grub opens, but doesn't cont. That is what happens with my Sony 2 in 1 laptop. My all in one portable just wont boot it period. Bios is the problem but I disabled everything that was necessary. Help

• 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?

• Are there any free hit counters that don't track users?

  - by David Englund

  Are there any free services that increment a simple hit counter without tracking the users of the site? I would like to know how many visitors there are to my site, excluding bots. I don't need detailed information like unique visitors or where the user is from (in fact, that's exactly what I don't want). I have been researching free hit counters, and it seems that most (all?) of them display advertisements and their terms of service indicate that they can use the data they collect from the client site however they want. Google Analytics also does this and tracks users across sites. The site is static HTML, so an external link or iframe of some sort is easiest for me to implement. I could switch to a Ruby or Node.js back-end, in which case lots of other options open up (like Ruby impressionist and more low-level implementations), but my hosting service is pretty limited. If the answer to my question is simply "no," what are my other options?

• Best choice for 3D Physics Engine for C#/XNA

  - by Nic Foster

  Since 2007 I've been working on the development of an open-source game engine, and have been using JigLibX for 3D Physics. However, the developers on the project have stopped contributing to it for over 2 years now, and it's lacking features I need, or have major bugs in certain features. What are some good choices for 3D physics engines that are written purely in C#? Are there any that are more complete than JigLibX? EDIT: I just stumbled upon an engine called BEPUphysics. It was supported up until May 2012, which is fairly recent. I may check it out, any information that you guys could give on how complete the engine is would be great.

• Using google maps as an input method

  - by Vasiliy Sharapov

  I'm wondering if it's possible to use gmaps pretty much as a type of input. Normally for Location a user has to enter: street address town/city state/province postal code country This seems too clunky to me, does anyone here know of a more elegant process? My perfect address-entering interface is a gmaps search bar with a map under it. When the user clicks a marker instead of a speech bubble containing location information they get one containing a submit button or equivalent. I'm not sure anything like this has been implemented before.

• T-SQL Tuesday #028: Whaddya Mean, “Not Your Job?”

  - by merrillaldrich

  This T-SQL Tuesday, hosted by Argenis Fernandez ( Blog | Twitter ) is devoted to the question, “Are you a Jack-of-all-Trades? Or a specialist?” This question really hits home for me, on a number of levels. (Aside: I have huge respect for Argenis – he’s smart, funny, no-nonsense, very accomplished. If you don’t follow him, do.) If you have read any of my previous ramblings on this blog, you may know I was originally educated as an architect – the bricks and mortar kind, not the information systems...(read more)

• Disable mobile page redirection for SharePoint 2013

  - by Sahil Malik

  SharePoint, WCF and Azure Trainings: more information SharePoint 2013 (foundation too), detects requests from mobile devices and automatically changes the uRL of the requested non mobile page to its mobile substitute. This logic is now built into SPRequestModule. The mobile view is pretty damned amazing. Even though the set of pages for mobile access is completely different, SharePoint has an entirely separate set of controls for the mobile pages. These are in the Microsoft.SharePoint.MobileControls namespace which inherit from Microsoft ASP.NET controls in the System.Web.UI.MobileControls namespace. These Mobile pages can even use mobile Web Part adapters to mimic the behavior of webparts on mobile webpart pages. Read full article ....

• Is there a pattern or logical structure I can follow for Event Log Numbers?

  - by makerofthings7

  What are some ideas or structure I can use when assigning EventID to events that will be saved to the Event Log? Some options I've considered Sequential (0... int.Max) Multiple of 10, where the "0" is replaced with how noisy the debugLevel is set. xxx0 may represent exceptions, critical information, start, stop etc. ...? What numbering approach gives you the most insight when a user describes the event in an email or phone? What is the most useful to support staff?

• How can I get my wireless webcam to work?

  - by hellocatfood

  I recently bought this wireless webcam. I'm having trouble getting it to work on Ubuntu 11.04. I ran lsusb and got the folowing information about the device Bus 006 Device 003: ID 0416:a91a Winbond Electronics Corp. I did a Google serach for teh device ID and this website informs me that it matches the LogiLink Wireless Webcam (so Maplin probably just rebranded this!). What this website states is that this device should work, which it doesn't. The problem I'm facing is that I don't get any actual video being streamed or shown. The built in microphone works and, when running Cheese, when I press the camera button on the webcam itself the software recognises that the button is pressed. On that note, when running cheese from the terminal with this webcam attached I get the following error libv4l2: error getting pixformat: Invalid argument libv4l2: error setting pixformat: Input/output error Any help is appreciated

• How to go about "taking over" an open-source project?

  - by LuxuryMode

  There's an open-source project that I'm interested in and use regularly. It's licensed under the Apache License 2.0 and it has basically no activity any more. It's hosted on Google Code and I'm interested in continuing it's development. I'm new to the open-source process and I'm trying to figure out the appropriate way to go about this. Can I just check it out and push it to github so I can continue it's development in the open there? Should I contact the project "owner" first? Also, do I leave all the author information at the top of the classes, etc even though I'm going to be making changes..(I'm assuming the answer is yes)? Also, how do I practically adhere to the license requirement of "all modifications are clearly marked as being the work of the modifier"? Do I place a comment by every change I make?

• SEO penalty for landing page redirects

  - by therealsix

  Using ebay as an example- lets say I have a large number of items whose URLs' look like this: cgi.ebay.com/ebaymotors/1981-VW-Vanagon-manual-seats-seven-/250953153841 I want to give my client the ability to put links to these items on their website EASILY, without knowing or checking my URL. So I created a redirect service that will map their identifier with my URL: ebay.com/fake_redirect_service/shared_identifier9918 would redirect to the link above. This works great- my clients can easily setup these links with information they already have, and the user will see the page as usual. So on to the problem... I'm concerned that this redirecting service will have a negative impact on my SEO ranking. Having a landing page redirect you immediately to a different URL seems like something a typical spam site would do. Will this hurt me? Any better solutions?

• Opinion : les framework web sont-ils synonymes du mal ? Partagez-vous l'avis de ce développeur PHP ? Expliquez nous pourquoi

  Opinion : les framework web sont-ils synonymes du mal ? J'ai récemment remarqué que personne n'a pris de recul sur les frameworks dédiés au langage PHP. Ils sont utilisés partout, ils sont devenus critères numéro un dans les recrutements de projets, ils sont l'équivalent d'une mode, etc. Bref, le framework est devenu le crucifix du développeur web. Mais un framework, est-ce vraiment que du bien? Non. En rassemblant une certaine quantité d'information trouvée sur quelques débats à propos de ceux-ci, j'ai décidé d'exprimer mon opinion sur l'utilisation d'un framework. Je trouve qu'un framework peut s'avérer être au sens propre le synonyme du mal. Avons-nous des statistiques sur l'utilisation des framewor...

• Results stored in a session - good idea?

  - by Nick

  To give a bit of background, lets say it's a generic results page, which is paginated so there are X results per page. Generally to do this, I have two queries on the page: to get the total number of results to get the results, limiting by the correct page's resultset However, recently I've been trying to cut down on the queries the site is making, and I thought one way to do this would be to only do the query if any parameters to the page have changed (except of course the page number)? This would then cache all the result id's in a session, which can be sliced when I need to return the correct resultset for that page. I was trying to look around the net to see if there are downsides of this method, but I've found very little information about it. Has anyone done this before? Is it a good idea?

• Unity session goes to lock on app launch, and won't unlock with password

  - by really

  Has been happening on every Ubuntu machine I've used to date, which is a total of 4. Started in 12.10 as far as I know, but it might have happened with 12.04, 12.10, 13.04, 13.10 and now 14.04. It doesn't seem to matter what I'm doing, but what always seems to trigger it is opening a web browser or some other application first from the sidebar. Firefox was was the most recent trigger. Instead of opening my browser, which it acts like it's going to do... the session locks, goes to the login screen, and won't unlock with the correct password. By 'won't unlock' I mean it unlocks then immediately locks again without first restoring unity, it does not produce 'incorrect password' I suspect this is a virus or password snooping software because of the fact it won't unlock with correct password information and I think if this IS a security issue, it should be fixed asap considering it's widespread throughout multiple versions. It's probably not a virus, but it is certainly suspicious behaviour to see your pc do that... wouldn't you think?

• Cannot save all of the property settings for this Web Part.

  - by ybbest

  I would like to display all the items of custom content type of Animals in a SharePoint content query WebPart. After choosing the appropriate values in the web part editor and click on Save I got this error: Cannot save all of the property settings for this Web Part. There is a problem with one or more of the field values below. But when I examine all the values below , it does not flag any error information. I finally manage to locate the error flag after I expand the presentation section. I then delete the text in the Link textbox , now I can save the settings. However , I think the error message should have been more specific so that users can quickly locate the error. The worst part for this is that I did not even change anything in the presentation section, I merely configure the Source in the Query section. Well, I guess I am still new to SharePoint, I just have to get used to these generic error message ):
