    - by andyleonard
    The Stairway to integration Services has been updated! I added content to Step 1 to provide more detail about creating a first SSIS project and corrected a typo in Step 2 that referred to an older name for the Step 1 article. I also made the corrected Step 1 article name a link to help. Thanks to Steve Jones ( blog | @way0utwest ) for all his hard work editing and corralling trifling authors. :{>...(read more)

  • Open Source PHP based secure file download script?

    - by SiddharthP
    Basically I need a self hosted solution where I as the admin can create client areas (which can be simple folders) where I upload files and secure them with username / pass. A client page will then be automatically generated which the client can access the username / pass and download the files. It's relatively simple script but i'm having a hard time finding open source solutions which accomplish what i need. Any help would be appreciated.

  • 2D camera perspective projection from 3D coordinates -- HOW?

    - by Jack
    I am developing a camera for a 2D game with a top-down view that has depth. It's almost a 3D camera. Basically, every object has a Z even though it is in 2D, and similarly to parallax layers their position, scale and rotation speed vary based on their Z. I guess this would be a perspective projection. But I am having trouble converting the objects' 3D coordinates into the 2D space of the screen so that everything has correct perspective and scale. I never learned matrices though I did dig the topic a bit today. I tried without using matrices thanks to this article but every attempt gave awkward results. I'm using ActionScript 3 and Flash 11+ (Starling), where the screen coordinates work like this: Left-handed coordinates system illustration I can explain further what I did if you want to help me sort out what's wrong, or you can directly tell me how you would do it properly. In case you prefer the former, read on. These are images showing the formulas I used: upload.wikimedia.org/math/1/c/8/1c89722619b756d05adb4ea38ee6f62b.png upload.wikimedia.org/math/d/4/0/d4069770c68cb8f1aa4b5cfc57e81bc3.png (Sorry new users can't post images, but both are from the wikipedia article linked above, section "Perspective projection". That's where you'll find what all variables mean, too) The long formula is greatly simplified because I believe a normal top-down 2D camera has no X/Y/Z rotation values (correct ?). Then it becomes d = a - c. Still, I can't get it to work. Maybe you could explain what numbers I should put in a(xyz), c(xyz), theta(xyz), and particularly, e(xyz) ? I don't quite get how e is different than c in my case. c.z is also an issue to me. If the Z of the camera's target object is 0, should the camera's Z be something like -600 ? ( = focal length of 600) Whatever I do, it's wrong. I only got it to work when I used arbitrary calculations that "looked" right, like most cameras with parallax layers seem to do, but that's fake! ;) If I want objects to travel between Z layers I might as well do it right. :) Thanks a lot for your help!

  • Was I wrong about JavaScript?

    - by jboyer
    Yes, I was. Recently, I’ve taken a good hard look at JavaScript. I’ve used it before but mostly in the capacity of web design. Using JQuery to make your web page do cool stuff is different than really creating a JavaScript application using all of the language constructs. What I’m finding as I use it more is that I may have been wrong about my assumptions about it. Let me explain.   I enjoyed doing cool stuff with JQuery but the limited experience with JavaScript as a language coupled with the bad things that I heard about it led me to not have any real interest in it. However, JavaScript is ubiquitous on the web and if I want to do any web development, which I do, I need to learn it. So here I am, diving deep into the language with the help of the JavaScript Fundamentals training course at Pluralsight (great training for a low price) and the JavaScript: The Good Parts book by Douglas Crockford.   Now, there are certainly parts of JavaScript that are bad. I think these are well known by any developer that uses it. The parts that I feel are especially egregious are the following: The global object null vs. undefined truthy and falsy limited (nearly nonexistent) scoping ‘==’ and ‘===’ (I just don’t get the reason for coercion)   However, what I am finding hiding under the covers of the bad things is a good language. I am finding that I am legitimately enjoying JavaScript. This I was not expecting. I’m not going to go into a huge dissertation on what I like about it, but some things include: Object literal notation dynamic typing functional style (JavaScript: The Good Parts describes it as LISP in C clothing) JSON (better than XML) There are parts of JavaScript that seem strange to OOP developers like myself. However, just because it is different or seems strange does not mean it is bad. Some differences are quite interesting and useful.   I feel that it is important for developers to challenge their assumptions and also to be able to admit when they are wrong on a topic. Many different situations can arise that lead to this, such as choosing the wrong technology for a problem’s solution, misunderstanding the requirements, etc. I decided to challenge my assumptions about JavaScript instead of moving straight into CoffeeScript or Dart. After exploring it, I find that I am beginning to enjoy it the more I use it. As long as there are those like Crockford to help guide me in the right way to code in JavaScript, I can create elegant and efficient solutions to problems and add another ‘arrow’ to the ‘quiver’, so to speak. I do still intend to learn CoffeeScript to see what the hub-bub is about, but now I no longer have to be afraid of JavaScript as a legitimate programming language.   Has something similar ever happened to you? Tell me about it in the comments below.

I wish to leverage help from open source community, to keep the language files for an open source project (Java) up to date. http://jstock.hg.sourceforge.net/hgweb/jstock/jstock/file/7871125356f7/src/org/yccheok/jstock/data Pootle seems good, as it supports Java language properties files as well. However, their official hosting site, is not opened for public registration. I was wondering, is there any free online translation tool hosting for Java open source project (Or similar) ?

  • Disk drive for / not ready on boot after upgrade from 10.04 to 12.04

    - by Mathieu M-Gosselin
    After upgrading (using the Upgrade button from the update manager) from 10.04.4 to 12.04.1, I cannot boot anymore. Upon booting, I am greeted with the Ubuntu logo and the error "The disk drive for / is not ready yet or not present". I have the option to wait, to skip and to access a basic shell. Waiting overnight did nothing, skipping just gives me the same error for /tmp, /home, then for a UUID and finally it just goes to a black screen with a white "_" in the top left corner. My setup is a dual boot one with XP on a single hard drive, I use separate partitions for / and /home. Back in the day I installed 8.04 directly from the CD while leaving a partition for XP, which I installed after. This setup had never caused any such issues, even when upgrading from 8.04 to 10.04. I have done plenty of research regarding this issue, as many others seem to have had similar issues after doing the same upgrade as me. However, while for most what fixed the problem was running: apt-get -f install after remounting / in read-write, it didn't do it for me. I got dependency errors (see here), which I also investigated. I found https://bugs.launchpad.net/ubuntu/+source/python-defaults/+bug/990740 where most people say the solution that worked is (prior to running the above command) running: apt-get install -o APT::Immediate-Configure=false -f apt python-minimal but that also got me a lot of dependencies errors as output (see here), similar to #34 in the above thread. I also read that running: dpkg --configure -a could help, at first it wouldn't run because it had trouble parsing /var/lib/dpkg/status since there was an extra blank line in a package description (see https://bugs.launchpad.net/ubuntu/+source/dpkg/+bug/916799) but I removed it using vim (and then reran the command). It still gives me output that looks like an error, though. Here it is: http://paste.ubuntu.com/1338074/. I also tried re-running the above apt-get commands after that, to no avail. I'm running out of things to try in the hope of getting this fixed, your help would be very much appreciated! Thank you in advance.

  • how to get rid of light desktop manager entry in ubuntu greeter

    - by user205162
    Got "light desktop manager" entry in ubuntu greeter for some strange reason and can't get rid of it. As the current OS is Ubunu 13.10 the way to configure the lightdm greeter is rather strange, can't find any solution in greeter configs. More annoying thing is that Mr.LDM seems to have password very hard to guess so I can't login to this "account". Can you help me to find source of this problem and find the solution?

  • Once installed geos library (C++, and C), and then trying to install rgeos package (R), it reports geos-config missing!

    - by user1873888
    Knowing that the package rgeos, from the R language, requieres a prior installation of geos libraries, I installed, both, libgeos and libgeos-c1 (3.2.2), using the synaptic installer in my Ubuntu 12.04 (32 bit) machine. Then I tried to install rgeos directly from the R console, and it issued a message in the sense that geos-config was not found.

  • Check if an object is facing another based on angles

    - by Isaiah
    I already have something that calculates the bearing angle to get one object to face another. You give it the positions and it returns the angle to get one to face the other. Now I need to figure out how tell if on object is facing toward another object within a specified field and I can't find any information about how to do this. The objects are obj1 and obj2. Their angles are at obj1.angle and obj2.angle. Their vectors are at obj1.pos and obj2.pos. It's in the format [x,y]. The angle to have one face directly at another is found with direction(obj1.pos,obj2.pos). I want to set the function up like this: isfacing(obj1,obj2,area){...} and return true/false depending if it's in the specified field area to the angle to directly see it. I've got a base like this: var isfacing = function (obj1,obj2,area){ var toface = direction(obj1.pos,obj2.pos); if(toface+area >= obj1.angle && ob1.angle >= toface-area){ return true; } return false; } But my problem is that the angles are in 360 degrees, never above 360 and never below 0. How can I account for that in this? If the first object's angle is say at 0 and say I subtract a field area of 20 or so. It'll check if it's less than -20! If I fix the -20 it becomes 340 but x < 340 isn't what I want, I'd have to x 340 in that case. Is there someone out there with more sleep than I that can help a new dev pulling an all-nighter just to get enemies to know if they're attacking in the right direction? I hope I'm making this harder than it seems. I'd just make them always face the main char if the producer didn't want attacks from behind to work while blocking. In which case I'll need the function above anyways. I've tried to give as much info as I can think would help. Also this is in 2d.
