  • What did I do wrong when installed this theme?

    - by Qmal
    I have a problem installing a theme for my Ubuntu, note that I am very new to it and probably messed something up. Still it seems to me that I did everything like it was stated in the INSTALL file. Theme: http://opendesktop.org/content/show.php/?content=140562 So I downloaded the *.zip package, unzipped it in home/.themes folder and changed Controls and Borders inside my theme preference. Still my result is pretty poor. You can look at the image, it looks nothing like what in the screenshot of the author. I also installed fonts running sudo apt-get install ttf-mscorefonts-installer and tried to install GTK2 engine as sudo apt-get install gtk2-engines-murrine gtk2-engines-pixbuf, but it showed that 0 files was modified since I already have it. Please tell me what did I did wrong so I can fix that :) (It seems that I can't upload images yet, no rep. I can give you link tho) http://postimage.org/image/1zhibxx5w/full/

  • HTML5 game programming style

    - by fnx
    I am currently trying learn javascript in form of HTML5 games. Stuff that I've done so far isn't too fancy since I'm still a beginner. My biggest concern so far has been that I don't really know what is the best way to code since I don't know the pros and cons of different methods, nor I've found any good explanations about them. So far I've been using the worst (and propably easiest) method of all (I think) since I'm just starting out, for example like this: var canvas = document.getElementById("canvas"); var ctx = canvas.getContext("2d"); var width = 640; var height = 480; var player = new Player("pic.png", 100, 100, ...); also some other global vars... function Player(imgSrc, x, y, ...) { this.sprite = new Image(); this.sprite.src = imgSrc; this.x = x; this.y = y; ... } Player.prototype.update = function() { // blah blah... } Player.prototype.draw = function() { // yada yada... } function GameLoop() { player.update(); player.draw(); setTimeout(GameLoop, 1000/60); } However, I've seen a few examples on the internet that look interesting, but I don't know how to properly code in these styles, nor do I know if there are names for them. These might not be the best examples but hopefully you'll get the point: 1: Game = { variables: { width: 640, height: 480, stuff: value }, init: function(args) { // some stuff here }, update: function(args) { // some stuff here }, draw: function(args) { // some stuff here }, }; // from http://codeincomplete.com/posts/2011/5/14/javascript_pong/ 2: function Game() { this.Initialize = function () { } this.LoadContent = function () { this.GameLoop = setInterval(this.RunGameLoop, this.DrawInterval); } this.RunGameLoop = function (game) { this.Update(); this.Draw(); } this.Update = function () { // update } this.Draw = function () { // draw game frame } } // from http://www.felinesoft.com/blog/index.php/2010/09/accelerated-game-programming-with-html5-and-canvas/ 3: var engine = {}; engine.canvas = document.getElementById('canvas'); engine.ctx = engine.canvas.getContext('2d'); engine.map = {}; engine.map.draw = function() { // draw map } engine.player = {}; engine.player.draw = function() { // draw player } // from http://that-guy.net/articles/ So I guess my questions are: Which is most CPU efficient, is there any difference between these styles at runtime? Which one allows for easy expandability? Which one is the most safe, or at least harder to hack? Are there any good websites where stuff like this is explained? or... Does it all come to just personal preferance? :)

  • client website compromised, found a strange .php file. any ideas?

    - by Kevin Strong
    I do support work for a web development company and I found a suspicious file today on the website of one of our clients called "hope.php" which contained several eval(gzuncompress(base64_decode('....'))) commands (which on a site like this, usually indicates that they've been hacked). Searching for the compromised site on google, we got a bunch of results which link to hope.php with various query strings that seem to generate different groups of seo terms like so: (the second result from the top is legitimate, all the rest are not) Here is the source of "hope.php": http://pastebin.com/7Ss4NjfA And here is the decoded version I got by replacing the eval()s with echo(): http://pastebin.com/m31Ys7q5 Any ideas where this came from or what it is doing? I've of course already removed the file from the server, but I've never seen code like this so I'm rather curious as to its origin. Where could I go to find more info about something like this?

  • Setting to protect gnome-terminal from key logging

    - by yanychar
    Looks like it is easy to log keystrokes of all processes of the same user. A basic keylogger is 'xinput'. xinput test-xi2 The command generates log of all key-presses. Unfortunately, this includes passwords in gnome-terminal. Googling suggested that grabbing keyboard may prevent other windows from capturing key strokes. Is there a way to prevent XI2 logging in gnome-terminal? Or is there an X terminal that has this feature?

  • Problem connecting to Webmin

    - by railguage48
    I have installed Webmin with the view to try an understand what is all running. Yesterday I had it setup with login and password, but today when I try to get access to the server with: https://ubuntu:10000/ in order to login, I get unable to connect, the page does not load. Seems like there is no connection. I tried http://localhost:10000 and https://localhost:10000 They both returned the same unable to connect response. I am not sure of what it means to turn https on. ... the https and http is not showing. Am I going about this the wrong way?

  • What is appropriate for creating a booking system?

    - by Joe
    I need a booking system for a theoretical project website. It would be an in-house job (not outsourcing to a web service) but all google searches on the subject yield results for said web services. I'd want to be able to use the system as such: For each day, there is availability recorded and if available a user can book in using the website, which sets that date to unavailable. There are other complexities, but this is the basic system I am trying to achieve - what would allow me to implement something like this?

  • How can I create multiple mini-sites with similar/duplicate content without hurting my search engine rank?

    - by ekpyrotic
    Essential background: I run a small company that lets members of the public post handwritten letters to their local politician (UK-based). Every week a number of early stage bills (called Early Day Motions) are submitted for debate in the House of Commons, and supporters of the motion will contact their local Members of Parliament, asking them to sign the motion. The crux: I want to target these EDMs with customised mini-sites, so when people search "EDM xxx", they find my customised mini-site, specifically targeting that EDM (i.e., "Send a handwritten letter to your MP asking them to sign EDM xxx"). At the moment, all these mini-sites (and my homepage) have duplicate content with only the relevant EDM name, number, and background image changed. (For example, http://mailmymp.com and http://mailmymp.com/edm/teaching-life-saving-skills-at-school-edm-550.php). The question: Firstly, will this hurt my potential search engine ranking? And, if so, what's the best way to target these political campaigns in an efficient manner without hurting my SEO prospects?

  • PASS Summit for SQL Starters

    - by Davide Mauri
    I’ve received a buch of emails from PASS Summit “First Timers” that are also somehow new to SQL Server (for “somehow” I mean people with less than 6 month experience but with some basic knowledge of SQL Server engine) or are catching up from SQL Server 2000. The common question regards the session one should not miss to have a broad view of the entire SQL Server platform have some insight into some specific areas of SQL Server Given that I’m on (semi-)vacantion and that I have more free time (not true, I have to prepare slides & demos for several conferences, PASS Summit  - Building the Agile Data Warehouse with SQL Server 2012 - and PASS 24H - Agile Data Warehousing with SQL Server 2012 - among them…but let’s pretend it to be true), I’ve decided to make a post to answer to this common questions. Of course this is my personal point of view and given the fact that the number and quality of session that will be delivered at PASS Summit is so high that is very difficoult to make a choice, fell free to jump into the discussion and leave your feedback or – even better – answer with another post. I’m sure it will be very helpful to all the SQL Server beginners out there. I’ve imposed to myself to choose 6 session at maximum for each Track. Why 6? Because it’s the maximum number of session you can follow in one day, and given that all the session will be on the Summit DVD, they are the answer to the following question: “If I have one day to spend in training, which session I should watch?”. Of course a Summit is not like a Course so a lot of very basics concept of well-established technologies won’t be found here. Analysis Services, Integration Services, MDX are not part of the Summit this time (at least for the basic part of them). Enough with that, let’s start with the session list ideal to have a good Overview of all the SQL Server Platform: Geospatial Data Types in SQL Server 2012 Inside Unstructured Data: SQL Server 2012 FileTable and Semantic Search XQuery and XML in SQL Server: Common Problems and Best Practice Solutions Microsoft's Big Play for Big Data Dashboards: When to Choose Which MSBI Tool Microsoft BI End-User Tools 360° for what concern Database Development, I recommend the following sessions Understanding Transaction Isolation Levels What to Look for in Execution Plans Improve Query Performance by Fixing Bad Parameter Sniffing A Window into Your Data: Using SQL Window Functions Practical Uses and Optimization of New T-SQL Features in SQL Server 2012 Taking MERGE Beyond the Basics For Business Intelligence Information Delivery Analyzing SSAS Data with Excel Building Compelling Power View Reports Managed Self-Service BI PowerPivot 101  SharePoint for Business Intelligence The Best Microsoft BI Tools You've Never Heard Of and for Business Intelligence Architecture & Development BI Power Hour Building a Tabular Model Database Enterprise Information Management: Bringing Together SSIS, DQS, and MDS SSIS Design Patterns Storing Columnstore Indexes Hadoop and Its Ecosystem Components in Action Beside the listed sessions, First Timers should also take a look the the page PASS set up for them: http://www.sqlpass.org/summit/2012/Connect/FirstTimers.aspx See you at PASS Summit!

  • RewriteRule working local but not on remote server

    - by m0tv
    I have a .htaccess file with one simple RewriteRule: RewriteEngine on RewriteRule ^([A-Za-z0-9-]+)$ ?site=$1 I want to have an url like http://www.example.com/imprint and forward it to http://www.example.com/?site=imprint I checked this rule with an RewriteRule tester which gave me the results I want to achieve. On my local development system it works well too. But on a remote server the URLs just give me a 404 error. Other more simple rewrite rules are working with no problems, so everything must be set up correctly (I think..). The problem is that I don't have access to any error logs or the server configs. So the only thing I can do is to guess... Can anyone tell me if theres something wrong with this rule? Or anything else I can do or test to solve this? Or has someone an idea what could be wrong on the server?

  • error: you need to load kernel first

    - by Angelos318
    I made a clean install on my Sony Vaio laptop, of Ubuntu 11.10 and when the installation was ready, it prompted to remove the usb I was installing the distro from, and press enter to reboot. After this reboot the first thing I got was the following error: error: couldn't read file error: you need to load the kernel first Press any key to continue.. After that it throws me back to the Grub select screen: Ubuntu, with linux 3.0.0-14-generic-pae recovery mode previous linux versions (none since I made a clean install) memory test If i choose the first option it shows only a black screen and never loads anything. If i reboot the same thing happens. Could I repair this using boot-repair? Is there any other way? Note: I know nothing about linux code so i am a total noob on this one Update: boot-repair did not help Grub.cfg here: http://pastebin.com/GKLuDuhM Boot Info Script: http://pastebin.com/indARkKJ

  • Add in the header of the license type is enough to say: "my code is licensed"? (Open-source)

    - by silverfox
    I do not know if this is the correct place to ask this stackexchange. Note: If a moderator can move to the correct place (if I am in the inappropriate site SE) I read on various sites about licenses. I did just put the license type in the header file (in my case the javascript file - open-source). /* * "codeName" "version" * http://officialsite.com/ * * Copyright 2012 "codeName" * Released under the "LICENSE NAME" license * http://officialsite.com/LICENSE NAME */ javascript code ... In the same folder I leave a copy of the license. The listing of the folder looks like this: * codeName.js * LICENSE In the file LICENSE would leave my code uses. What nobody says is if it is enough to say my code is licensed (the case of an open-source). Or is something more required? Sorry for the bad English. Thanks.

  • design practice for business layer when supporting API versioning

    - by user1186065
    Is there any design pattern or practice recommended for business layer when dealing with multiple API version. For example, I have something like this. http://site.com/blogs/v1/?count=10 which calls business object method GetAllBlogs(int count) to get information http://site.com/blogs/v2/?blog_count=20 which calls business object method GetAllBlogs_v2(int blogCounts) Since parameter name is changed, I created another business method for version 2. This is just one example but it could have other breaking changes for which it requires me to create another method to support both version. Is there any design pattern or best practice for business/data access layer I should follow when supporting API Versioning?

  • Can I use one set of images to represent multiple sprites in Java?

    - by mal
    I've got a game that has 3 basic sprites, at the moment I'm loading 8 images into each sprite for animating. Each character class has a sprite object. if I've got 10 characters on screen at once then that's 80 images loaded in to memory. Can I make a central sprite class that only holds 8 images for each of the 3 sprites, then get the character objects to request the relevant images from the central sprite class, thereby massively reducing the memory required for the images?

  • wrong SEO result for staging website

    - by OCD
    Hi, We have a domain with URL, lets say: http://www.xxxxstaging.com/abc.php?id=10 which is having a pretty good ranking for some keywords in google. However, this is our staging website and due to some historical reason, it was exposed to public. Now we have a production domain (the one we want to be publicly available), say: http://www.xxxxproduction.com/abc.php?id=10 which have exactly the same html output as xxxxstaging.com our question is, for the exactly same keyword search, it never appear in any page of google. Is it possible for us to "switch" the ranking in google, either tell the robot that they are indeed the same website, or tell google to change it for us? Thank you.

  • Cloud Infrastructure has a new standard

    - by macoracle
    I have been working for more than two years now in the DMTF working group tasked with creating a Cloud Management standard. That work has culminated in the release today of the Cloud Infrastructure Management Interface (CIMI) version 1.0 by the DMTF. CIMI is a single interface that a cloud consumer can use to manage their cloud infrastructure in multiple clouds. As CIMI is adopted by the cloud vendors, no more will you need to adapt client code to each of the proprietary interfaces from these multiple vendors. Unlike a de facto standard where typically one vendor has change control over the interface, and everyone else has to reverse engineer the inner workings of it, CIMI is a de jure standard that is under change control of a standards body. One reason the standard took two years to create is that we factored in use cases, requirements and contributed APIs from multiple vendors. These vendors have products shipping today and as a result CIMI has a strong foundation in real world experience. What does CIMI allow? CIMI is both a model for the resources (computing, storage networking) in the cloud as well as a RESTful protocol binding to HTTP. This means that to create a Machine (guest VM) for example, the client creates a “document” that represents the Machine resource and sends it to the server using HTTP. CIMI allows the resources to be encoded in either JavaScript Object Notation (JSON) or the eXentsible Markup Language (XML). CIMI provides a model for the resources that can be mapped to any existing cloud infrastructure offering on the market. There are some features in CIMI that may not be supported by every cloud, but CIMI also supports the discovery of which features are implemented. This means that you can still have a client that works across multiple clouds and is able to take full advantage of the features in each of them. Isn’t it too early for a standard? A key feature of a successful standard is that it allows for compatible extensions to occur within the core framework of the interface itself. CIMI’s feature discovery (through metadata) is used to convey to the client that additional features that may be vendor specific have been implemented. As multiple vendors implement such features, they become candidates to add the future versions of CIMI. Thus innovation can continue in the cloud space without being slowed down by a lowest common denominator type of specification. Since CIMI was developed in the open by dozens of stakeholders who are already implementing infrastructure clouds, I expect to CIMI being adopted by these same companies and others over the next year or two. Cloud Customers who can see the benefit of this standard should start to ask their cloud vendors to show a CIMI implementation in their roadmap.  For more information on CIMI and the DMTF's other cloud efforts, go to: http://dmtf.org/cloud

  • Redirect Google crawler to different robots.txt via .htaccess

    - by user3474818
    I have googled for the answer all day and still couldn't find an answer. I have a virtual subdomain www.static.example.com which is a mirror site of www.example.com. It means I have just one root folder for subdomain and domain aswell. I want to redirect crawlers to different robots.txt file - robots_static.txt when they see .static in url in which I will forbid indexing via /disallow command. I want to do this because I have duplicated content in Google search results. Subdomain is showing the exact same content as the main domain. Does anyone know how could I achieve that crawlers sees robots_static.txt instead of robots.txt? What I have managed to find so far is this: RewriteCond %{HTTP_HOST} ^www.static.*$ [NC] RewriteCond %{THE_REQUEST} ^[A-Z]{3,9}\ /.*robots\.txt.*\ HTTP/ [NC] RewriteRule ^robots\.txt /robots_static.txt [NC,L] but when I check in webmaster tools, it still sees robots.txt as my robots file instead of robots_static.txt, so it crawls and index everything twice.

  • What's the best way to learn image processing?

    - by rdasxy
    I'm a senior in college that hasn't done much image processing before (except for some basic image compression on smartphones). I'm starting a research project on machine learning next semester that would require some biomedical image processing. What's the best way to get up to speed with the basics of image processing in about two months? Or is this impractical? It's my impression that once I'm good with the basics learning more from other resources would be easier.
