  • Best Game Engine/Framework and Language for 2D actor/sprite intensive game

    - by Grungetastic
    I'm new to the game dev world. I have a rather large project in mind (I learn by setting myself challenges :P ) and I'm wondering what the best engine/framework/language is for a 2D game with thousands of sprites/actors on screen at a time. Bare metal type stuff. I need to still be able to zoom in and out with that many actors at once. This game will have no 3D elements. Any thoughts? Suggestions?

  • XBMC freezes pc after viewing movies

    - by Eric
    Tough to replicate, but basically after watching any movie in my library on XBMC, it'll randomly start freezing my pc. All I can do is either force shutdown by holding down the power button or wait for it to shut itself down. It's not any particular movie, it's not any particular amount of time watching one. It only happens while using XBMC. PC is older, I know the hardware is outdated, but it's not overheating nor is a simple movie too much for it to play, at least I don't think it is. Specs: Intel Core 2 6400. nVidia Quardro FX 560 4GB RAM So any suggestions? I don't have any bug/error reports because it doesn't print out any. I'm trying to find a program like XBMC, as I like having my movies organized and not have to hunt through folders to find them, so any suggestions there?

  • Creating symlink for Postgres

    - by Edwin
    As a developer, I often ssh right into my local database, just to test my application before pushing my code. However, I find that every time I want to access Postgres, I have to type in postgres@ubuntu:~$ /usr/local/pgsql/bin/psql test whereas on my work machine, all I have to do is type postgres@ubuntu:~$ psql --dbname=test --username=user I tried creating a symlink, which was successful, but whenever I try connecting to it through this shortcut, I get the following error message: psql: could not connect to server: No such file or directory Is the server running locally and accepting connections on Unix domain socket "/var/run/postgresql/.s.PGSQL.5432"? How do I get this to work? In case it makes any difference, I'm using a self-compiled version of the 9.1.x series.

  • New T-SQL Functionality in SQL Server 2008

    - by ejohnson2010
    In my most recent posts I have looked at a few of the new features offered in T-SQL in SQL Server 2008. In this post, I want to take a closer look at some of the smaller additions, but additions that are likely to pack a big punch in terms of efficiency. First let’s talk a little about compound operators. This is a concept that has been around in programming languages for a long time, but has just now found its way into T-SQL. For example, the += operator will add the values to the current variable...(read more)

  • Trouble signing Code of Conduct

    - by Lionthinker
    So I've spent quite some time trying to sign this code of conduct and am on the verge of abandoning it. Got right to the sign the txt file stage https://launchpad.net/codeofconduct/1.1/+sign but now I get an error and am just tired of fighting with Ubuntu. It has to do with the clearsign thing in the terminal. See below $ gpg --clearsign UbuntuCodeofConduct-1.1.txt You need a passphrase to unlock the secret key for user: "Leon Gert Marincowitz (for launchpad) <[email protected]>" 2048-bit RSA key, ID 715FBC94, created 2012-06-16 gpg: can't open `UbuntuCodeofConduct-1.1.txt': No such file or directory gpg: UbuntuCodeofConduct-1.1.txt: clearsign failed: file open error

  • HP Pavilion g6 1190sm laptop has overheat/hibernation/graphics issues

    - by Jan
    Every time I reboot or shutdown my laptop, while the laptop is booting again I get a screen (before loading the OS) that HP discovered overheating and system went into hibernation. But the point is that the laptop is not overheating nor going into hibernation by itself. Also, because of the hybrid graphics card I cannot install additional drivers. Desktop resolution and all works perfectly but I cannot use Unity 3D. Also, OpenGL doesn't work as it should (with Cairo Dock). As I've read some posts, people say that vgaswitcheroo doesn't work on 12.04 so I haven't tried it.

  • How to Delete/Disable gnome panels. No existing solutions working

    - by Alan Peabody
    I would like to remove gnome panel completely. I spend most of my time in a (tmux) terminal or a browser. Synapse and a small hidden AWN panel fit the rest of my needs. I have tried all recommended solutions including this (found it a few places): How to delete Gnome Panel? However it always comes back at log in. I have tried changing the required components panel to avant-whatever as well as to empty. I have tried setting them both as default (right click set as default). Right now I just have the last panel set to transparent and auto hide, but it still tends to be annoying. What do I need to do to get rid of this damn thing? Clarification: Using gconf-editor, gconftool2, and/or Ubuntu tweak to set /desktop/gnome/session/required_component/panel to avant-window-navigator is not working. The setting stays when I reboot, but the empty gnome panel sticks around.

  • Samsung Series 5 overheating

    - by Sean Brad
    I bought a Samsung Series 5 Ultra 2 weeks ago and installed Ubuntu 12.04 LTS. I am experiencing problems with overheating. When streaming, watching a movie or when having several programms/actions going on at the same time the CPU temperature rises to 95 degrees and the computer freezes. This happens sometimes when the computer is on battery and always when it is recharging. When I am using the computer on battery the CPU temperature is floating from around 75-95 degrees depending what it's doing. When the battery is recharging the CPU temperature is ranging from 88-95 degrees no matter what tasks it performs. Have anyone experienced this and how may the problem be solved? Best regards

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

    - 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.

  • Download mirrors down after fresh installation

    - by user169866
    I dont know whats the problem but it seems after every fresh installation of ubuntu in any device (have started noticing this problem since ubuntu 11.04) the connection to the software sources are down. I cannot download any software from either apt-get or software center. Also i cannot use the Universal Source for packages like chromium, etc. And then suddenly after a few days, the mirrors are back up again!! Its normal back again! I dont know what the problem is, but it happens every time. Is there any solution to this or we just have to wait for a few days till the mirrors are back again? (and I have also tried changing the download server, It doesn't helps!)

  • Panel Background color, Transparency and background image don't work with Ambiance theme

    - by Ash G
    As the title suggests. Selecting a background image, color or using the transparency sitting doesn't work with the Ambiance theme. Sections of the panel will take the new settings, but many of the applets including the clock, Indicator Applet Session, Indicator Applet, Rhythmbox icon, Tomboy Icon, Separators and various others retain the Ambiance theme background. This carries over through restart. Also you cannot resize the panel in Ambiance above 24 pixels as the background image doesn't scale. Am I doing something wrong, is it a bug or is it meant to be like that? I really like Ambiance, but am having a hard time using it because of these issues Edit: It seems these issues carry over to Radiance and New Wave as well

  • Does semi-normalization exist as a concept? Is it "normalized"?

    - by Gracchus
    If you don't mind, a tldr on my experience: My experience tldr I have an application that's heavily dependent upon uncertainty, a bane to database design. I tried to normalize it as best as I could according to the capabilities of my database of choice, but a "simple" query took 50ms to read. Nosql appeals to me, but I can't trust myself with it, and besides, normalization has cut down my debugging time immensely over and over. Instead of 100% normalization, I made semi-redundant 1:1 tables with very wide primary keys and equivalent foreign keys. Read times dropped to a few ms, and write times barely degraded. The semi-normalized point Given this reality, that anyone who's tried to rely upon views of fully normalized data is aware of, is this concept codified? Is it as simple as having wide unique and foreign keys, or are there any hidden secrets to this technique? Or is uncertainty merely a special case that has extremely limited application and can be left on the ash heap?

  • Shifting from no-www to www and browsers' password storage

    - by user1444680
    I created a website having user-registration system and invited my friend to join it. I gave him the link of no-www version: http://mydomain.com but now after reading this and this, I want to shift to www.mydomain.com. But there's a problem. I saw that my browser is storing separate passwords for mydomain.com and www.mydomain.com. So in my friend's browser his password must have been stored for no-www. That means after I shift to www and next time he opens the login page, his browser wouldn't auto-fill the username and password fields and there will also be an extra entry (of no-www) in his browser's database of stored passwords. Can this be avoided? Can I do something that will convey to browsers that www.mydomain.com and mydomain.com are the same website? I already have a CNAME record for www pointing to mydomain.com but it seems that search engines consider CNAME as alias but browsers consider them as different websites, I don't know why.

  • How to resolve "Google can't find your site's robots.txt" error?

    - by Manivasagam
    I've recently found that "Google can't find your site's robots.txt" in crawl errors. When I tried Fetching as Google, I got result "SUCCESS", then I tried looking at crawl errors and it still shows "Google can't find your site's robots.txt". What can I do to resolve this issue? Before this issue arose, my site was indexed within a few mintues, but now I find that it took time to be indexed in Google's search. When I access http://mydomain.com/robots.txt, it shows the data below: User-agent: *Disallow: /wp-admin/ Disallow: /wp-includes/ I found Blocked URLs = 0, also no any other errors. Is there any other thing I need to change? Or what could be the solution for this? Any help would be appreciated.

  • The Business Case for a Platform Approach

    - by Naresh Persaud
    Most customers have assembled a collection of Identity Management products over time, as they have reacted to industry regulations, compliance mandates and security threats, typically selecting best of breed products.  The resulting infrastructure is a patchwork of systems that has served the short term IDM goals, but is overly complex, hard to manage and cannot scale to meets the needs of the future social/mobile enterprise. The solution is to rethink Identity Management as a Platform, rather than individual products. Aberdeen Research has shown that taking a vendor integrated platform approach to Identity Management can reduce cost, make your IT organization more responsive to the needs of a changing business environment, and reduce audit deficiencies.  View the slide show below to see how companies like Agilent, Cisco, ING Bank and Toyota have all built the business case and embraced the Oracle Identity Management Platform approach.

  • PostgreSQL data diff

    - by skanatek
    Note: this question is not about syncing database schema/structure Problem In my web application I have a PostgreSQL database server (PGS) and a (separate machine) business logic server (BLS) which regularly (every minute or two) queries 'SELECT ALL' against PGS. The problem is that the 'SELECT ALL' query can easily return 50-200 MB each time. It is obvious that it would be not so good architecture-wise to transfer so much data so frequently over the web. Possible solution What I would like to do is to run some diff tool on PGS and compare the new query with the previous query (all this should be done on PGS). Once the comparison is done I would like to get a dump from PGS and transfer it to BLS. I expect that a diff-based dump would be much, much smaller than the whole 'SELECT ALL' query. Question Is there any data diff tool for PostgreSQL that can do diffs that compare PostgreSQL data between 2 tables or 2 dumps? Note: I would prefer some open-source software tool.

  • 12.10 Booting Into Variations Of Blank Screen

    - by user93954
    I've been running the Ubuntu 12.10 beta since about a month before the final release with almost no problems. However since the day of release (I'm assuming an update has caused this) I have had problems booting into the actual GUI interface. Trying to get it to work is just a case of hard shutting down until it works, but for most of the time I need to battle with various different kinds of black screens. These include a plain black screen, a flashing line and a flashing line that doesn't fit the resolution. Nine times out of ten the cursor will be displayed over these. It also sometimes manages to boot into Ubuntu, albeit text mode or sometimes it loads GRUB which it isn't setup to do. If anyone could help out with this it'd be great. I really, really don't want to have to go through yet another clean installation. Cheers.
