• Functional Programming, JavaScript and UI - some neophyte questions

  - by jamesson

  This has been discussed in other threads, however I am hoping for some comments relevant to UI and an explanation of some vitriol I had flung my way in a Certain IRC Channel Which shall remain nameless. In the discussion here, the comments in the accepted answer suggest that I approach the given code from a functional perspective, which was new to me at the time. Wikipedia said, among other things, that FP "avoids state and mutable data", which includes according to the discussion global vars. Now, being that I am already pretty far along in my project I am not going to learn FP before I finish, but... How is it possible to avoid global vars if, for instance, I have a UI whose entire functionality changes if a mousebutton is down? I have a number of things like this. Why was there a strong negative reaction in the Certain IRC channel to implementing FP in JS? When I Brought up what seemed to me to be supportive comments by Crockford, people got even madder. Now, this being IRC there is no rep system, but they at least gave indication of having read TGP (which I haven't gotten to yet) so I'm assuming they're not idiots. Many thanks in advance Joe

• Neophyte question about using Subtotal and CountIf in Excel

  - by Andrew

  Hi, I'm using Excel and having some problems with Countif and I don't understand how it works differently from SubTotal. I used the GUI to subtotal stuff and all the subtotals are right. Then I attempted to use the Countif to see how many requirements passed. That worked for the first subtotal only. It's easy to see why. When I look at the box for the subtotal, it says: =SUBTOTAL(3,C286:C292) When I look at my formula for passed requirements, I have: =IF(ISTEXT(A285),COUNTIF(C286:C338,"=Passed"),"") Notice that the last column is wrong. How did the Subtotal manage to keep this correct? I typed in the formula for passed requirements and dragged it down the page. Everything behaved as expected (even the bit about ISTEXT dutifully figured out which row was which), but it got the last row wrong. Any ideas?

• Essential Dojo

  - by Carl Manaster

  I'm starting to use Dojo; this is (essentially) my introduction to AJAX. We have a Java backend (torque / turbine / velocity) and are using the jabsorb JSON-RPC library to bridge Java and Javascript. What do I need to know? What is the big picture of Dojo and JSON, and what are the nasty little details that will catch me up? What did you spend a couple of days tracking down, when you started with Dojo, that you now take for granted? Thanks for any and all tips.

• Why does Unity in 2d mode employ scaling and the default othographic size the way it does?

  - by Neophyte

  I previously used SFML, XNA, Monogame, etc to create 2d games, where if I display a 100px sprite on the screen, it will take up 100px. If I use 128px tiles to create a background, the first tile will be at (0,0) while the second will be at (129,0). Unity on the other hand, has its own odd unit system, scaling on all transforms, pixel-to-units, othographic size, etc etc. So my question is two-fold, namely: Why does Unity have this system by default for 2d? Is it for mobile dev? Is there a big benefit I'm not seeing? How can I setup my environment, so that if I have a 128x128 sprite in Photoshop, it displays as a 128x128 sprite in Unity when I run my game? Note that I am targeting desktop exclusively.

• How can I cleanly and elegantly handle data and dependancies between classes

  - by Neophyte

  I'm working on 2d topdown game in SFML 2, and need to find an elegant way in which everything will work and fit together. Allow me to explain. I have a number of classes that inherit from an abstract base that provides a draw method and an update method to all the classes. In the game loop, I call update and then draw on each class, I imagine this is a pretty common approach. I have classes for tiles, collisions, the player and a resource manager that contains all the tiles/images/textures. Due to the way input works in SFML I decided to have each class handle input (if required) in its update call. Up until now I have been passing in dependencies as needed, for example, in the player class when a movement key is pressed, I call a method on the collision class to check if the position the player wants to move to will be a collision, and only move the player if there is no collision. This works fine for the most part, but I believe it can be done better, I'm just not sure how. I now have more complex things I need to implement, eg: a player is able to walk up to an object on the ground, press a key to pick it up/loot it and it will then show up in inventory. This means that a few things need to happen: Check if the player is in range of a lootable item on keypress, else do not proceed. Find the item. Update the sprite texture on the item from its default texture to a "looted" texture. Update the collision for the item: it might have changed shape or been removed completely. Inventory needs to be updated with the added item. How do I make everything communicate? With my current system I will end up with my classes going out of scope, and method calls to each other all over the place. I could tie up all the classes in one big manager and give each one a reference to the parent manager class, but this seems only slightly better. Any help/advice would be greatly appreciated! If anything is unclear, I'm happy to expand on things.

• Fast, accurate 2d collision

  - by Neophyte

  I'm working on a 2d topdown shooter, and now need to go beyond my basic rectangle bounding box collision system. I have large levels with many different sprites, all of which are different shapes and sizes. The textures for the sprites are all square png files with transparent backgrounds, so I also need a way to only have a collision when the player walks into the coloured part of the texture, and not the transparent background. I plan to handle collision as follows: Check if any sprites are in range of the player Do a rect bounding box collision test Do an accurate collision (Where I need help) I don't mind advanced techniques, as I want to get this right with all my requirements in mind, but I'm not sure how to approach this. What techniques or even libraries to try. I know that I will probably need to create and store some kind of shape that accurately represents each sprite minus the transparent background. I've read that per pixel is slow, so given my large levels and number of objects I don't think that would be suitable. I've also looked at Box2d, but haven't been able to find much documentation, or any examples of how to get it up and running with SFML.

  Getting a new Toshiba C55D Touchscreen Laptop next week and want to run strictly Ubuntu and Firefox. Want to rip every scrap of Microsoft off of it (it comes pre-loaded). I'm a neophyte to Ubuntu and the finer points of setting up a laptop.

• PASS Summit 2012, Day 1

  - by KKline

  One of the most positive experiences I can have, as a former leader of the PASS organization, is when I see a neophyte become a passionate support and champion for the community. On my first day in Seattle, before the event had even begun, I was stopped several by people who'd attended their first PASS Summit last year. But this year, they were excited to tell me that they'd started user groups in their own community, spoken for the first time at a PASS event, or even helped launch a SQL Saturday...(read more)

• The Secret to Driving Huge Traffic While Gaining More Money Online Finally Revealed

  Even neophyte internet marketers recognize the weight of a keyword research tool in any online business. Although you may not be truly familiar with how to make use of one yet, you must understand that sooner or later, you need to be trained if you want to be ahead of the competition. This is for the reason that keywords determine principally just how much traffic and sales your business will benefit from.

• OpenID authentication in Ruby on Rails

  - by martinatime

  I am a neophyte with Ruby on Rails but I've created a couple of small apps. Anyway, I'm really interested in OpenID and I would like to implement OpenID authentication and maybe some Sreg stuff in a Rails app. All of the research that I have done has come up with articles that are out of date or just don't work for me. Since I'm so new to Rails I'm having difficulty debugging the issues so... What is the best way to implement OpenId in Rails? Thanks

• Fixed-Function vs Shaders: Which for beginner?

  - by Rob Hays

  I'm currently going to college for computer science. Although I do plan on utilizing an existing engine at some point to create a small game, my aim right now is towards learning the fundamentals: namely, 3D programming. I've already done some research regarding the choice between DirectX and OpenGL, and the general sentiment that came out of that was that whether you choose OpenGL or DirectX as your training-wheels platform, a lot of the knowledge is transferrable to the other platform. Therefore, since OpenGL is supported by more systems (probably a silly reason to choose what to learn), I decided that I'm going to learn OpenGL first. After I made this decision to learn OpenGL, I did some more research and found out about a dichotomy that I was somewhere unaware of all this time: fixed-function OpenGL vs. modern programmable shader-based OpenGL. At first, I thought it was an obvious choice that I should choose to learn shader-based OpenGL since that's what's most commonly used in the industry today. However, I then stumbled upon the very popular Learning Modern 3D Graphics Programming by Jason L. McKesson, located here: http://www.arcsynthesis.org/gltut/ I read through the introductory bits, and in the "About This Book" section, the author states: "First, much of what is learned with this approach must be inevitably abandoned when the user encounters a graphics problem that must be solved with programmability. Programmability wipes out almost all of the fixed function pipeline, so the knowledge does not easily transfer." yet at the same time also makes the case that fixed-functionality provides an easier, more immediate learning curve for beginners by stating: "It is generally considered easiest to teach neophyte graphics programmers using the fixed function pipeline." Naturally, you can see why I might be conflicted about which paradigm to learn: Do I spend a lot of time learning (and then later unlearning) the ways of fixed-functionality, or do I choose to start out with shaders? My primary concern is that modern programmable shaders somehow require the programmer to already understand the fixed-function pipeline, but I doubt that's the case. TL;DR == As an aspiring game graphics programmer, is it in my best interest to learn 3D programming through fixed-functionality or modern shader-based programming?

• LinkSys WRT54GL + AM200 in half-bridge mode - Setup guide recommendations?

  - by Peter Mounce

  I am basically looking for a good guide on how to set up my home network with this set of hardware. I need: Dynamic DNS Firewall + port-forwarding VPN Wake-on-LAN from outside firewall VOIP would be nice QoS would be nice (make torrents take lower priority to other services when those other services are happening) DHCP Wireless + WPA2 security Ability to play multiplayer computer games I am not a networking or computing neophyte, but the last time I messed with network gear was a few years ago, so am needing to dust off knowledge I kinda half have. I have read that I should be wanting to set up the AM200 in half-bridge mode, so that the WRT54GL gets the WAN IP - this sounds like a good idea, but I'd still like to be advised. I have read that the dd-wrt firmware will meet my needs (though I gather I'll need the vpn-specific build, which appears to preclude supporting VOIP), but I'm not wedded to using it. My ISP supplies me with: a block of 8 static IPs, of which 5 are usable to me a PPPoA ADSL2+ connection

• Transitioning to Branching with TFS

  - by Rob

  Our team is currently using plain old TFS 2005, no branching, shared checkouts etc... I would like to introduce a DEV/MAIN/PROD branching system simillar to the basic flavor in the TFS Guidance document so that we can do some parallel dev, isolation, and firm up review and deployment processes. I have read most of the whitepapers etc. Do you guys have any practical advice, suggested tools, gotchas or reccomendations. Also, we plan to migrate to 2010 once it comes out - not sure if that would affect anything. I appreciate all the suggestions and help I can get as I am a branching neophyte. Thanks in advance.

• String formatting [str.format()] with a dictionary having a key which is a str() of a number

  - by decimus phostle

  Python neophyte here. I was wondering if someone could help with the KeyError I am getting when using a dictionary for string interpolation in str.format. dictionary = {'key1': 'val1', '1': 'val2'} string1 = 'Interpolating {0[key1]}'.format(dictionary) print string1 The above works fine and yields: Interpolating val1 However doing the following: dictionary = {'key1': 'val1', '1': 'val2'} string2 = 'Interpolating {0[1]}'.format(dictionary) print string2 results in: Traceback (most recent call last): File "test.py", line 3, in <module> string2 = 'Interpolating {0[1]}'.format(dictionary) KeyError: 1L So the problem seems to be in the interpretation of the numeric key as a list index, IMHO. Is there any way to work around this? (i.e. convey that this is instead a dictionary key) TIA and apologies if this question has been asked before(couldn't find anything relevant with my search-fu).

• Tables in the SQL Server "master" database, will they cause problems?

  - by pepoluan

  Folks, please be kind on me... I'm just an 'accidental' DBA due to our DBA resigned, so I'm totally a newbie in DBA... You see, I have this application, "ESET Remote Administration Server" (ERAS) that stores its logs and analysis on (originally) a local Access database. The decision was to migrate its database to a SQL Server 2008 R2 machine. ESET (the maker of the software) helpfully provided tools to perform such migration; unfortunately, being the DBA neophyte that I am, I didn't realize that I have to first create my own database (on the SQL Server side) and assign that database as the 'default' database for ERAS' ODBC connection. Now, the migration tool had successfully created a whole bunch of tables inside the "master" database. My questions: Should I leave things be as it is, or should I re-migrate the ERAS database to a different database? If you suggest me perform a re-migration, my plan is to (1) create a new instance, (2) create a new database within the new instance, (3) create a new ODBC System DSN on the ERAS server pointing to the new DB in step 2, (4) use ESET's migration tool to migrate from the current DSN to the new DSN. Do you think I missed a step there? Thanks beforehand for any guidance.

• Array of Objects

  - by James

  Complete and utter neophyte to Objective-C and the entire Mac platform so don't flame me please =). Basically I'm trying to create a simple game. The game has a board which I've created a class for and a board is comprised of squares which I also created a class for (board and square respectively). In my view controller I'm trying to instantiate a board and add boardSize^2 squares to said object. board contains an NSMutableArray *squares. I've also created a convenience method which sets an NSNumber *boardSize called initWithDimension. In my touchesBegan handler I have the following: board *game_board = [[board alloc] initWithDimension:10]; int size = [game_board.boardSize intValue]; for(int i = 0; i <= size; i++) { square *s = [[square alloc] init]; [game_board.squares addObject:s]; [s release]; } NSLog(@"%i", size); NSLog(@"%@", [game_board.squares objectAtIndex:0]); ...and I'm getting 10 (as expected) and then (null). This is probably glaringly obvious to an experienced developer, I've just struggled for an hour trying to solve it and have given up. I've tried it without the [s release] as well, same result. I've also imported square.h and board.h. Any ideas what's wrong here? Any other comments on what I'm brutalizing? Thanks.

• need primitive public key signature with out of band key distribution

  - by Mike D

  I pretty much a complete neophyte at this signature business so I don't know if what I'm asking is nonsense or not. Anyway, here goes... I want to send an out of band message (don't worry about how it gets there) to a program I've written on a distant machine. I want the program to have some confidence the message is legit by attaching a digital signature to the message. The message will be small less than 200 characters. It seems a public key based signature is what I want to use. I could embed the public key in the program. I understand that the program would be vulnerable to attack by anyone who modifies it BUT I'm not too worried about that. The consequences are not dire. I've looked through the MSDN and around the web but the prospect of diving in is daunting. I'm writing in straight c++, no NET framework or other fancy stuff. I've had no experience including NET framework stuff and little luck during previous attempts. Can anyone point me at some very basic resources to get me started? I need to know 1)how to generate the public and private keys 2)how to sign the message 3)how to verify the signature Any help much appreciated. TIA, Mike

• Passing a list of ints to WebMethod using jQuery and ajax.

  - by birdus

  I'm working on a web page (ASP.NET 4.0) and am just starting simple to try and get this ajax call working (I'm an ajax/jQuery neophyte) and I'm getting an error on the call. Here's the js: var TestParams = new Object; TestParams.Items = new Object; TestParams.Items[0] = 1; TestParams.Items[1] = 5; TestParams.Items[2] = 10; var finalObj = JSON.stringify(TestParams); var _url = 'AdvancedSearch.aspx/TestMethod'; $(document).ready(function () { $.ajax({ type: "POST", url: _url, data: finalObj, contentType: "application/json; charset=utf-8", dataType: "json", success: function (msg) { $(".main").html(msg.d); }, error: function (xhr, ajaxOptions, thrownError) { alert(thrownError.toString()); } }); Here's the method in my code behind file: [Serializable] public class TestParams { public List<int> Items { get; set; } } public partial class Search : Page { [WebMethod] public static string TestMethod(TestParams testParams) { // I never hit a breakpoint in here // do some stuff // return some stuff return ""; } } Here's the stringified json I'm sending back: {"Items":{"0":1,"1":5,"2":10}} When I run it, I get this error: Microsoft JScript runtime error: 'undefined' is null or not an object It breaks on the error function. I've also tried this variation on building the json (based on a sample on a website) with this final json: var TestParams = new Object; TestParams.Positions = new Object; TestParams.Positions[0] = 1; TestParams.Positions[1] = 5; TestParams.Positions[2] = 10; var DTO = new Object; DTO.positions = TestParams; var finalObj = JSON.stringify(DTO) {"positions":{"Positions":{"0":1,"1":5,"2":10}}} Same error message. It doesn't seem like it should be hard to send a list of ints from a web page to my webmethod. Any ideas? Thanks, Jay

• how often should the entire suite of a system's unit tests be run?

  - by gerryLowry

  Generally, I'm still very much a unit testing neophyte. BTW, you may also see this question on other forums like xUnit.net, et cetera, because it's an important question to me. I apoligize in advance for my cross posting; your opinions are very important to me and not everyone in this forum belongs to the other forums too. I was looking at a large decade old legacy system which has had over 700 unit tests written recently (700 is just a small beginning). The tests happen to be written in MSTest but this question applies to all testing frameworks AFAIK. When I ran, via vs2008 "ALL TESTS", the final count was only seven tests. That's about 1% of the total tests that have been written to date. MORE INFORMATION: The ASP.NET MVC 2 RTM source code, including its unit tests, is available on CodePlex; those unit tests are also written in MSTest even though (an irrelevant fact) Brad Wilson later joined the ASP.NET MVC team as its Senior Programmer. All 2000 plus tests get run, not just a few. QUESTION: given that AFAIK the purpose of unit tests is to identify breakages in the SUT, am I correct in thinking that the "best practice" is to always, or at least very frequently, run all of the tests? Thank you. Regards, Gerry (Lowry)

• Project Euler #14 and memoization in Clojure

  - by dbyrne

  As a neophyte clojurian, it was recommended to me that I go through the Project Euler problems as a way to learn the language. Its definitely a great way to improve your skills and gain confidence. I just finished up my answer to problem #14. It works fine, but to get it running efficiently I had to implement some memoization. I couldn't use the prepackaged memoize function because of the way my code was structured, and I think it was a good experience to roll my own anyways. My question is if there is a good way to encapsulate my cache within the function itself, or if I have to define an external cache like I have done. Also, any tips to make my code more idiomatic would be appreciated. (use 'clojure.test) (def mem (atom {})) (with-test (defn chain-length ([x] (chain-length x x 0)) ([start-val x c] (if-let [e (last(find @mem x))] (let [ret (+ c e)] (swap! mem assoc start-val ret) ret) (if (<= x 1) (let [ret (+ c 1)] (swap! mem assoc start-val ret) ret) (if (even? x) (recur start-val (/ x 2) (+ c 1)) (recur start-val (+ 1 (* x 3)) (+ c 1))))))) (is (= 10 (chain-length 13)))) (with-test (defn longest-chain ([] (longest-chain 2 0 0)) ([c max start-num] (if (>= c 1000000) start-num (let [l (chain-length c)] (if (> l max) (recur (+ 1 c) l c) (recur (+ 1 c) max start-num)))))) (is (= 837799 (longest-chain))))
