  • How much isometric sprites can one optimize by mirroring and alike?

    - by Tom
    I am working on a basic isometric game, and am struggling to find the correct mirrors. I have managed to get SE out of SW, by scaling the sprite on X axis by -1. Same applies for NE angle. Something is bugging me, that I should be able to also mirror N to S, but I cannot manage to pull this one off. Am I just too sleepy and trying to do the impossible, or a basic -1 scale on Y axis is not enough? What are the common used mirror table for optimizing 8 angle (N, NE, E, SE, S, SW, W, NW) isometric sprites?

  • Best book/source to learn the unix commands

    - by Kraken
    So I was intern at this company wherein they'd use just putty. Now I've never worked with unix commands, apart from the basic , compile code , run C code. But now I would love to know all the things about the unix. Starting off with the commands, from the most basic of all to the decent level. Also, moving forward, how the different folders/files are arranged in a unix (ubuntu is installed on my system) system. I have picked up a couple of books, but they dont seem to help. Can someone suggest a comprehensive book that'll fulfill my needs. Because, working with a GUI on ubuntu does not really give me the real feel of things. Hence I'd want to move on to the terminal instead. Thanks.

  • How to add metadata to images using Shotwell

    - by mcaleaa
    Using Ubuntu 13.04. I have a very basic question about Shotwell. I would like to add a desciption to my photos. I right-click on an image in Nautilus. Choose Open with Shotwell photo viewer. I can't find a way to edit any metadata for the photo. As an example, Shotwell help: http://yorba.org/shotwell/help/view-view.html ... says that I should be able to select Photos Edit title, but I don't have this option in my menu. (I have 'Photo' but not 'Photos'). F2 does nothing for me. My menu options are: File, Edit, View, Photo, Help. I'm missing something very basic here. Grateful for your help!

  • Gone in 60 Seconds: An Insecure Database is an Easy Target

    - by Troy Kitch
    According to the recent Verizon Data Breach Investigations Report, 98% of breached data originates from database servers and nearly half are compromised in less than a minute! Almost all victims are not even aware of a breach until a third party notifies them and nearly all breaches could have been avoided through the use of basic controls. Join us for this November 28th webcast to learn more about the evolving threats to databases that have resulted in over 1 billion stolen records. Also, hear how organizations can mitigate risks by adopting a defense-in-depth strategy that focuses on basic controls to secure data at the source - the database. There's no turning back the clock on stolen data, but you can put in place controls to ensure your organization won't be the next headline. Note, this webcast will be recorded for on-demand access after November 28th.

  • Without using a pre-built physics engine, how can I implement 3-D collision detection from scratch?

    - by Andy Harglesis
    I want to tackle some basic 3-D collision detection and was wondering how engines handle this and give you a pretty interface and make it so easy ... I want to do it all myself, however. 2-D collision detection is extremely simple and can be done multiple ways that even beginner programmers could think up: 1.When the pixels touch; 2.when a rectangle range is exceeded; 3.when a pixel object is detected near another one in a pixel-based rendering engine. But 3-D is different with one dimension, but complex in many more so ... what are the general, basic understanding/examples on how 3-D collision detection can be implemented? Think two shaded, OpenGL cubes that are moved next to each other with a simple OpenGL rendering context and keyboard events.

  • Restricting A Directory Through .htaccess

    - by Whitechapel
    I'm trying to put all of my FTP accounts into a folder on /public_html/ftp and password protect it so search bots can't crawl their private files. I'm also trying to redirect all site traffic from the non-www to www. I keep getting 500 errors when accessing the site, and I need to point it to www.vivalanation.com/ftp to www.vivalanation.com/ftp/, because the /ftp just errors out, you need the trailing slash. Here is my .htaccess in the /public_html/ftp folder: RewriteEngine on RewriteBase / RewriteCond %{HTTP_HOST} !^www\. [NC] RewriteRule ^(.*)$ http://www.%{HTTP_HOST}/$1 [R=301,L] AuthName "FTP Access" AuthType Basic AuthUserFile /home1/vivalst/.htpasswds/public_html/ftp/passwd Require valid-user I created a passwd file in /.htpasswds/public_html/ftp And here is my basic .htaccess in the root of /public_html/: RewriteEngine on RewriteBase / RewriteCond %{HTTP_HOST} !^www\.

  • java application architecture

    - by LostMohican
    We have to write an administration panel for many customers. But we want to have just one administration panel, and use it in various projects. This admin panel will have basic components such as access control logic, maker-checker system in changes, user logging and etc. It will also have reporting for the customer, logs of transaction of the customer (which can vary according to the industry such as mobile banking, banking, ticket sales). These components may have to be modified according to the business. So we are thinking about the architecture here, Is it OK to use jars of every basic components, and bring them together on a glue application? Or should we build each component as WARs and make interfaces between them? If there are any more ideas, it will be appreciated.

  • Why we need apache Tomcat server to deploy any application. or what are the requirements to deploy any code or release?

    - by Shank_SCM
    I am asking very basic concept as I am new to build and release team. I am working with ant scripts to build and deploy the java code + working with TFS to deploy .net code. So my question is: What is apache tomcat and why we need it? Can't we deploy any piece of code or any application without apache tomcat? For windows, what framework we need to deploy(or same tomcat can be used for same)? Please make me understand the basic concept so that I can understand the deploy process or per-requisites of deploying process. what I know (to deploy) Just copy the tar file or zip file to any concerned dev environment and restart the server. Thats it. Please correct me if I am wrong.

  • Vector transform equation explanation

    - by cyberdemon
    I'm trying to understand the maths of moving points in a 3d space by making a game written in C#. I'm looking at this wolfire blog series which explains some basic 3d maths. I've read the first two parts but am stuck on the 3rd. I know it's all really rudimentary stuff but I find Googling for help with equations really hard. The one I'm struggling with is: 0*(0.66,0.75) + 2*(-0.75, 0.66) = (-1.5, 1.3) How can anything multiplied by 0 not be 0? So my question is how does this look in code: x(a,b) + y(c,d) I know it's basic stuff but I just can't see it.

  • Looking for a previous post about skillsets for an embedded/firmware engineer. Can't find it anymore [closed]

    - by Sandiego
    I remember reading a post inquiring the basic/advanced skills required for embedded engineer works. The top comment divides the answer into two parts, the basic level/design level ,not purely coding(something like this...). Then another level : writing application(all about programming). For each level/category, the top comment talks about the necessary skills/knowledge/college courses(for me at least) . While I was searching for this post as I was trying to read it again, I found similar questions, but these are not the one I saw: http://stackoverflow.com/questions/1091931/what-skill-set-should-a-low-level-programmer-possess http://stackoverflow.com/questions/45247/how-do-i-get-started-in-embedded-programming http://electronics.stackexchange.com/questions/3343/how-to-become-an-embedded-software-developer Has anyone seen the post I'm talking about? This is a repost from Stackoverflow where I was told that this question is off-topic. So..please help guys

  • Django - no module named app

    - by Koran
    Hi, I have been trying to get an application written in django working - but it is not working at all. I have been working on for some time too - and it is working on dev-server perfectly.

  • Resons why I'm using php rather then asp.net [closed]

    - by spirytus
    I have basic idea of how asp .Net works, but finds all framework hard to use if you are a newbie. I found compiling, web applications vs websites and all that stuff you should know to program in asp .net a bit tedious and so personally I go with php to create small, to medium applications for my clients. There are couple of reasons for it: php is easy scripting language, top to bottom and you done. You still can create objects, classes and if you have idea of MVC its fairly easy to create basic structure yourself so you can keep you presentation layer "relatively" clean. Although I find myself still mixing basic logic in my view's, I am trying to stick to booleans, and for each loops. ASP .net keeps it cleaner as far as I know and I agree that this is great. Heaps of free stuff for php and lots of help everywhere Although choice of IDE's for php is very limited, I still don't have to be stuck with VisualStudio. Lets be honest.. you can program in whatever you like but does anyone uses anything else other than VS? For basic applications I create, Visual Studio doesn't come even close to notepad :) / phpEdit (or similar) combination. It lacks of many features I constantly use, although armies of developers are using it and it must be for good reason. Personally not a big fan of VS though. Being on the market for that long should make editing much easier. I know .Net comes with awesome set of controls, validators etc. which is truly awesome. For me the problem starts if I want my validator to behave slightly different way and lets say fade in/out error messages. I know its possible to extend it behavior, plug into lifecycle and output different JS to the client and so on. I just never see it happen in places I work, and honestly, I don't even think most of .net developers I worked with during last couple of years would know how to do that. In php I have to grab some plugin for jQuery and use it for validation, which is fairly easy task once you had done it before. Again I'm sure its easy for .net gurus, but for newbie like me its almost impossible. I found that many asp .net programmers are very limited in what they are able to do and basically whack together .net applications using same lame set of controls, not even bothering in looking into how it works and what if? Now I don't want to anger anyone :) I know there is huge number of excellent .Net developers who know their stuff and are able to extend controls and do all that magic in no time. I found it a bit annoying though that many of them stick to what is provided without even trying to make it better. Nothing against .net here, just a thought really :) I remember when asp.net came out the idea was that front-end people will not be able to screw anything up and do their fron-end stuff without worrying what happens behind. Now its never that easy and I always tend to get server side people to fix this and that during development. Things like ID's assigned to controls can very easily make your application break and if someone is pure HTML guy using VS its easy to break something. Thats my thoughs on php and .net and reasons why for my work I go with php. I know that once learned asp .net is awesome technology and summing all up php doesn't even come close to it. For someone like me however, individually developing small basic applications for clients, php seems to work much better. Please let me know your thoughts on the above :)

  • Foreign Key constraint violation when persisting a many-to-one class

  • How do I configure freeSSHd on Windows Server 2008 so I can log in using ssh?

    - by Daryl Spitzer
    I've installed freeSSHd on a Windows Server 2008 box (following the instructions in How to install an SSH Server in Windows Server 2008), including: created a user named "dspitzer" with NTLM authorization opened an exception for port 22 in the Windows Firewall But when I try to connect (from a Mac OS X 10.5.8 command-line), I get permission denied after entering the password: $ ssh 12.34.56.78 [email protected]'s password: Permission denied, please try again. [email protected]'s password: Permission denied, please try again. [email protected]'s password: Received disconnect from 12.34.56.78: 2: Too many attempts.

[email protected]'s password: Received disconnect from 12.34.56.78: 2: Too many attempts. I've also tried changing the authorization to "Password stored as SHA1 hash" and entering a simple password, but I get the same problem. And I've tried a different user name ("Administrator") with no luck. I've confirmed that I am connecting to the server I'm configuring—if I stop freeSSHd and try to connect I get: $ ssh 12.34.56.78 ssh: connect to host 12.34.56.78 port 22: Operation timed out I get the exact same results from a Linux command-line. Any advice or troubleshooting tips? Update: I tried disabling the firewall (in response to geeklin's comment) and it made no difference. Update #2: I no longer have this machine (I've changed employers), so I have no way of verifying the answers. I guess all I can do is make this question "community wiki".

Update #2: I no longer have this machine (I've changed employers), so I have no way of verifying the answers. I guess all I can do is make this question "community wiki".

  • Cisco 891w multiple VLAN configuration

    - by Jessica
    I'm having trouble getting my guest network up. I have VLAN 1 that contains all our network resources (servers, desktops, printers, etc). I have the wireless configured to use VLAN1 but authenticate with wpa2 enterprise. The guest network I just wanted to be open or configured with a simple WPA2 personal password on it's own VLAN2. I've looked at tons of documentation and it should be working but I can't even authenticate on the guest network! I've posted this on cisco's support forum a week ago but no one has really responded. I could really use some help. So if anyone could take a look at the configurations I posted and steer me in the right direction I would be extremely grateful.

  • Configure ApacheDS 1.5 with accessControlEnabled=true for authenticated access

    - by cmyers
    I need to set up an apacheDS instance. I am using standalone 1.5.5 on Linux. I have removed the example partition and added two of my own, each with their own suffixes. I have imported LDIFs for the two partitions and everything looks correct data-wise. I need to configure ApacheDS to disallow anonymous access. I was able to do that by following some of the directions here: http://directory.apache.org/apacheds/1.5/145-enable-and-disable-anonymous-access.html http://directory.apache.org/apacheds/1.5/32-basic-authorization.html Now only the administrator account (uid=admin,ou=system) can log in and make queries. I need to establish an admin account, and a "regular user" account which can read and write only certain entries within each partition. I tried to read the above docs and I got nuthin'. The second page "basic authorization" is completely incomprehensible to me. When I tried to add a "prescriptiveACI" to it using Apache Directory Studio, I get: Administration point 2.5.4.11=abc,2.5.4.10=efg does not contain an administrativeRole attribute! An administrativeRole attribute in the administrative point is required to add a subordinate subentry. where my partition is "ou=abc,o=def". I have no clue what is going on and the docs are really not helping, I am at a complete loss here. How can it possibly be this hard to just restrict access? P.S. can someone with proper rep please change the tag "apache" to the new tag "ApacheDS"?
