• Why should I use Bower? [closed]

  - by Wil

  I can fully appreciate the benefits of a package manager like Python PIP, Node npm, or Ruby Gems since they're doing much more than adding files to your applications path. Maybe I'm missing the point, or I'm being obtuse, but here are the negatives I can see: Separate step when building a project Separate dependency to install via another package manager (yo dawg) More clutter in the projects root with bower.json and / or .bowerrc Reliance on the registry being up to date, correct, and available Some imports / references to things like images won't work The positives I can see are these: I don't have to download the dependencies manually Optionally install packages as part of scaffolding based on user prompts or the like I'd really like to know of any benefits I'm unaware of, and I should say I'm not trying to be provocative I genuinely want to know.

• Is there a list of shortcuts which are not reserved in any major browser?

  - by MainMa

  In the past, when I implemented shortcuts for web applications, I used different ones for different browsers: for example Ctrl+Shift+A was used in Chrome, but would be something else, like Ctrl+Shift+C in Firefox, since Firefox reserves the Ctrl+Shift+A shortcut for add-ons. Actually, I have a project where it would be nice to have the same shortcuts for every browser. Is there a list of shortcuts which are not reserved in any major browser (Chrome, Firefox, Safari, IE and Opera) or do I have to do my own by listing? Google wasn't helpful, since it rather shows the list of shortcuts which are common to all major browsers.

• Programming methodologies at stackoverflow

  - by Prototype Stark

  I am in the middle of starting up a software company where we would use ASP.NET MVC and ASP.NET WebAPI extensively at shop. We will be a group of 4 and no more than 10 will work on any particular project at any point in time(these are ground rules). I would like to know, what programming methodologies best suit a small(guerilla) team. Specifically, I would also like to know which ones are being used at famous ASP.NET MVC shops like Stackoverflow. The ones I know are: Scrum and Waterfall(I know its bad). But what's the recommended way of development for smaller, group of 9-10 team. Also, will Test Driven Development help such a team in producing quality software? Are there any other techniques the team will have to know to be good at producing quality software?

• Author's work and copyright. in UI design

  - by c-smile

  Typical situation in UI design: you do design of some UI and, say, came up with some bright new idea like "ribbon" or "kinetic scroll past end". What would be the strategy about such thing? Register patent, don't like it, but anyway would like to ask: how long it takes to do all this stuff and how much it will cost in average? If to forget about patents, will the idea have something like "prior art" status or some such if someone will try to patent this in future? All this about project / product published by solo developer.

• Smartassembly 5: it lives! Early Access builds now available

  - by Bart Read

  I'm pleased to announce that, late last week, we put out the first early access build for Smartassembly 5, Red Gate's fantastic code protection and error reporting tool, which we acquired last September. You can download it via: http://www.red-gate.com/messageboard/viewforum.php?f=116 It's obviously pretty early days, so please do not try to use this to protect a production application, but we've already done a lot of work in some key areas: We're simplifying and streamlining the licensing model (you won't see this yet, but a lot of the work on this has already been done). We've improved usability of the product, with a better menu, reordering of project settings, and better defaults. We've also fixed a load of bugs, which I'll let Alex blog about in more detail. On a slightly more trivial level, the curly braces are also no more. Over the coming weeks, we'll be adding more improvements, and starting usability tests. If you're interested in getting involved in the latter, please drop an email to [email protected].

• Understanding encryption Keys

  - by claws

  Hello, I'm really embarrassed to ask this question but its the fact that I don't know anything about encryption. I always avoided it. I don't understand the concept of encryption keys (public key, private key, RSA key, DSA key, PGP Key, SSH key & what not) . I did encounter these in regular basis but as I said I always avoided them. Here are few instances where I encountered: Creating Account: A public RSA or DSA key will be needed for an account. Send the key along with your desired account name to [email protected] I really don't know what are RSA/DSA or How to get their keys? Do I need to register some where for that? Mailing: I'm unable to recall exactly but I've seen some mails have some attachments like signature or the mail footer will have something called PGP signature etc.. I really don't get its concept. GIT Version control: I created account in assembla.com (for private GIT repo) and it asked me to enter "SSH keys" to my profile. Where am I gonna get these? Why do I need it? Isn't SSH related to remote login (like remote desktop or telnet)? How are these two SSHs related & differ? I don't know in how many more situations I'm going to encounter these things. I'm really confused and have no clue about where to start & how to proceed to learn these things. Kindly someone point me in correct direction. Note: I've absolutely zero interested in encryption related topics. So, there is no way I'm going to read a graduate level book on this subject. I just want to clear my concepts without going into much depth.

• How can I get the business analysts more involved in BDD?

  - by Robert S.

  I am a proponent of Behavior Driven Development, mainly with Cucumber and RSpec, and at my current gig (a Microsoft shop) I am introducing SpecFlow as a tool to help with testing. I'd like to get the business analysts on my team involved in writing the features and scenarios, but they are put off by the "technical" aspect of it, meaning creating the files in Visual Studio (or even having Visual Studio on their machines). They want to know if we can put all the scenarios for a feature in Jira. What I'm looking for is suggestions for a workflow that will work well with BA types that are accustomed to project management/work tracking tools like Jira (we also use Greenhopper).

• Does this exist: a standardized way of documenting a file-system structure

  - by eegg

  At work, I'm in charge of maintaining the organization of a whole lot of varied data on a standard file-system. Part of this is coming up with sensible classification (by similarity, need, read/write access, etc), but the bigger part is actually documenting it: what documents/files/media should go where, what should not be in this directory, "for something slightly different, see ../../other-dir", etc. At the moment, I've documented this using a plaintext file filing.txt in every directory I want to document. If someone is unsure what's meant to be in any directory, they read that file. This works alright, but it seems odd that I have this primitive custom solution to a problem that any maintainer of a non-trivial directory structure must experience. Every company I've known of, for example, has some kind of shared file-system where agreed terminology for categorization is important. In my experience, people just have to learn what's what by trial-and-error and experimentation. So allow me to propose a better solution, and hopefully you can tell me if it exists. Any directory on any filesystem can have a hidden plaintext file named .filing. Its contents are descriptive human language. It uses some markup like Markdown, with little more than bold, italic, and (relative) hyperlinks to other directories. Now a suitably-enabled file browser will check for a file named .filing whenever it displays a directory. If it exists, its contents are parsed and displayed in an unobtrusive pane near the directory-path widget. Any links therein can be clicked, and the user will be taken to the target directory of that link. I think that the effort of implementing such a standard would pay back many times over in usability gains. We would have, say, plugins for Nautilus, Konqueror, etc.. It could be used to display directory information in the standard file lists served by webservers. And so on. So, question: does such a thing exist? If not, why not? Do people think it's a worthwhile idea?

• What does this snippet work? It uses session cookie [closed]

  - by Emerald214

  My website is a gadget application. It uses CakePHP framework. It has the below snippet in AppController. I searched the cookie variable in the project but can't find any other occurences. I also don't understand what it works. Why does it always check this in every request. if ( isset( $_COOKIE[session_name()] ) ) { if ( !isset( $this->sns_id ) ) { // ????????? $this->cakeError( 'session' ); } } else { // ?????????????????? if ( !isset( $_REQUEST['post_pf_params'] ) ) { $this->cakeError( 'cookie' ); } }

• What are the real life implications for an Apache 2 license?

  - by Duopixel

  I want to use SVG Edit for project. This software is distributed under the Apache 2 license. I've seen that: all copies, modified or unmodified, are accompanied by a copy of the licence all modifications are clearly marked as being the work of the modifier all notices of copyright, trademark and patent rights are reproduced accurately in distributed copies the licensee does not use any trademarks that belong to the licensor Do these pertain to the code or should I display the license somewhere in the GUI? The orignal software displays a "powered by SVG Edit", is it ok if I remove this? And most importantly: what is the correct etiquette for doing this? I don't want to be an asshole, but at the same time I want to simplify the UI as much as possible and removing the link will be part of it if it's not considered rude.

• Having a generic data type for a database table column, is it "good" practice?

  - by Yanick Rochon

  I'm working on a PHP project where some object (class member) may contain different data type. For example : class Property { private $_id; // (PK) private $_ref_id; // the object reference id (FK) private $_name; // the name of the property private $_type; // 'string', 'int', 'float(n,m)', 'datetime', etc. private $_data; // ... // ..snip.. public getters/setters } Now, I need to perform some persistence on these objects. Some properties may be a text data type, but nothing bigger than what a varchar may hold. Also, later on, I need to be able to perform searches and sorting. Is it a good practice to use a single database table for this (ie. is there a non negligible performance impact)? If it's "acceptable", then what could be the data type for the data column?

• WCF web service with Neural Network

  - by Gary Frank

  I am developing a web service that performs object recognition. It will be available for testing as soon as enough code has been developed, and then officially when it is finished. It is based on a radically new type of artificial neural network that I designed. Its goal is to recognize any type of object within an image. Besides the WCF web service, the project will also create a website to test and demonstrate the web service. Here is a link with more information. http://www.indiegogo.com/VOR

• Independent projects as a student to show off abilities

  - by tufcat

  I'm an inexperienced student (having learned up to data structures and algorithms through various online resources) of computer science, and I'm hoping to get a job as a developer some time after I've gotten a few independent projects done. My question is, how should I choose which projects to work on? I've been looking around stackoverflow-- people usually say to pick whatever you're interested in, but I don't have enough experience to even know what specifically I'm interested in, and possibly more importantly, I don't know what some common beginner project types are. Essentially, I'm at the gap between course work (and the projects entailed in those classes) and real programming, and I don't quite know how to start. If any of you have any ideas, I'd really appreciate it.

• New videos available #dax #ssas #powerpivot

  - by Marco Russo (SQLBI)

  The collaboration I and Alberto started with Project Botticelli is starting producing content. At this point we have three videos available: DAX in Action shows the power of DAX in PowerPivot solving common patterns not so easy or fast to solve in other languages DAX: Calculated Columns vs. Measures shows the difference between calculated columns and measures in DAX Introduction to DAX has a content corresponding to the title! The first two videos are freely available, the third one is longer and visible only to subscribers. The goal for this series of video is to reach advanced Excel users and BI developers that are new to DAX. If we should categorize this content, it’s a sort of level 200 session in a conference. I don’t expect readers of this blog to watch this video (if not for the sake of curiosity!) but if you have to explain this subject to anyone else and you have other priorities… well, you can add this post to the list of resources you provide for studying the subject!

• Attached Property port of my Window Close Behavior

  - by Reed

  Nishant Sivakumar just posted a nice article on The Code Project.  It is a port of the MVVM-friendly Blend Behavior I wrote about in a previous article to WPF using Attached Properties. While similar to the WindowCloseBehavior code I posted on the Expression Code Gallery, Nishant Sivakumar’s version works in WPF without taking a dependency on the Expression Blend SDK. I highly recommend reading this article: Handling a Window’s Closed and Closing Events in the View-Model.  It is a very nice alternative approach to this common problem in MVVM.

• Formalizing programmers errors

  - by Maksee

  Every one of us make errors leading to bugs. Once I wanted to start logging my errors for future analysis, probably mentioning project title, approximate time spent and the most important, the type of error. For example when I copy-pasted a fragment about 'x' and replaced every occurrence of 'x' with 'y' and forgot to replace a tiny piece, this goes to 'copy-paste error'. The usefulness of this approach depends on whether I can formalize my errors at all and probably minimizing the number of types to choose from. Otherwise I would start postponing, ignoring and so on so make this system useless. Are there existing research in this area, probably a known minimum set of errors? Maybe some of you already tried to implement something like this and succeeded/failed?

• Are there existing FOSS component-based frameworks?

  - by Tesserex

  The component based game programming paradigm is becoming much more popular. I was wondering, are there any projects out there that offer a reusable component framework? In any language, I guess I don't care about that. It's not for my own project, I'm just curious. Specifically I mean are there projects that include a base Entity class, a base Component class, and maybe some standard components? It would then be much easier starting a game if you didn't want to reinvent the wheel, or maybe you want a GraphicsComponent that does sprites with Direct3D, but you figure it's already been done a dozen times. A quick Googling turns up Rusher. Has anyone heard of this / does anyone use it? If there are no popular ones, then why not? Is it too difficult to make something like this reusable, and they need heavy customization? In my own implementation I found a lot of boilerplate that could be shoved into a framework.

• MPL with Commercial Use Restrictions (And Other Questions)

  - by PythEch

  So basicly I want to use MPL 2.0 for my open source software but I also want to forbid commercial use. I'm not a legal expert, that's why I'm asking. Should I use dual-license (MPL + Modified BSD License)? Or what does sublicensing mean? If I wanted to license my project, I would include a notice to the header. What should I do if want to dual-license or sublicense? Also, is it OK to use nicknames as copyright owners? I am not able to distribute additional files (e.g LICENSE.txt, README.md etc) with the software simply because it is just a JS script. By open-source I mean not obfuscated JS code. So in this case, am I forced to use GPL to make redistribution of obfuscated work illegal? Thanks for reading, any help is appreciated, answering all of the questions is not essential.

• How can you become a real programming polyglot?

  - by Yob

  I work as a Java programmer, but C and C++ were always my favourite languages during studies. Unfortunatelly I don't have an opportunity to work with them as often as I would like to. As a result I sometimes get realized that I don't remember something quite important (today example: inherited protected members cannot be accessed in derived class constructors). The other example could be Python and Haskell which I enjoy using but don't use everyday. I got an idea to write my own wiki with easy to forget things (e.g. bash tricks & tips) but I find no sense in writing there everything I can forget about coolest programming languages. I know that the best way would be having a side projects (I want to start working on some C/C++ open source project after graduation), but currently I have to write my graduation thesis and work so I merely don't have time to do this. How do you stay sharp in languages that you don't use everyday?

• better way to track defect sources in tfs

  - by deostroll

  What is the best way to track defect sources in tfs? We have various teams for a project like the vulnerability team, the customer, pre-sales, etc. We give a build and these teams independently test it. They do not have access to our tfs system. So they usually send in their defects via email. It will usually be send in an excel format. Our testing team takes these up and logs them into tfs. Sometimes they modify the original defect description (in excel) and add the expected/actual results. Sometimes they miss to cite the source. I am talking about managing the various sources as such. Is there a way we can add these sources into tfs, and actually link this particular source with the defects, with individual comments associated with them (saying where in the source we can find the actual material for the defect).

• Create association between informations

  - by Andrea Girardi

  I deployed a project some days ago that allow to extract some medical articles using the results of a questionnaire completed by a user. For instance, if I reply on questionnaire I'm affected by Diabetes type 2 and I'm a smoker, my algorithm extracts all articles related to diabetes bubbling up all articles contains information about Diabetes type 2 and smoking. Basically we created a list of topic and, for every topic we define a kind of "guideline" that allows to extract and order informations for a user. I'm quite sure there are some better way to put on relationship two content but I was not able to find them on network. Could you suggest my a model, algorithm or paper to better understand this kind of problem and that helps me to find a faster, and more accurate way to extract information for an user?

• Trouble with AABB collision response and physics

  - by WCM

  I have been racking my brain trying to figure out a problem I am having with physics and basic AABB collision response. I am fairly close as the physics are mostly right. Gravity feels good and movement is solid. The issue I am running into is that when I land on the test block in my project, I can jump off of it most of the time. If I repeatedly jump in place, I will eventually get stuck one or two pixels below the surface of the test block. If I try to jump, I can become free of the other block, but it will happen again a few jumps later. I feel like I am missing something really obvious with this. I have two functions that support the detection and function to return a vector for the overlap of the two rectangle bounding boxes. I have a single update method that is processing the physics and collision for the entity. I feel like I am missing something very simple, like an ordering of the physics vs. collision response handling. Any thoughts or help can be appreciated. I apologize for the format of the code, tis prototype code mostly. The collision detection function: public static bool Collides(Rectangle source, Rectangle target) { if (source.Right < target.Left || source.Bottom < target.Top || source.Left > target.Right || source.Top > target.Bottom) { return false; } return true; } The overlap function: public static Vector2 GetMinimumTranslation(Rectangle source, Rectangle target) { Vector2 mtd = new Vector2(); Vector2 amin = source.Min(); Vector2 amax = source.Max(); Vector2 bmin = target.Min(); Vector2 bmax = target.Max(); float left = (bmin.X - amax.X); float right = (bmax.X - amin.X); float top = (bmin.Y - amax.Y); float bottom = (bmax.Y - amin.Y); if (left > 0 || right < 0) return Vector2.Zero; if (top > 0 || bottom < 0) return Vector2.Zero; if (Math.Abs(left) < right) mtd.X = left; else mtd.X = right; if (Math.Abs(top) < bottom) mtd.Y = top; else mtd.Y = bottom; // 0 the axis with the largest mtd value. if (Math.Abs(mtd.X) < Math.Abs(mtd.Y)) mtd.Y = 0; else mtd.X = 0; return mtd; } The update routine (gravity = 0.001f, jumpHeight = 0.35f, moveAmount = 0.15f): public void Update(GameTime gameTime) { Acceleration.Y = gravity; Position += new Vector2((float)(movement * moveAmount * gameTime.ElapsedGameTime.TotalMilliseconds), (float)(Velocity.Y * gameTime.ElapsedGameTime.TotalMilliseconds)); Velocity.Y += Acceleration.Y; Vector2 previousPosition = new Vector2((int)Position.X, (int)Position.Y); KeyboardState keyboard = Keyboard.GetState(); movement = 0; if (keyboard.IsKeyDown(Keys.Left)) { movement -= 1; } if (keyboard.IsKeyDown(Keys.Right)) { movement += 1; } if (Position.Y + 16 > GameClass.Instance.GraphicsDevice.Viewport.Height) { Velocity.Y = 0; Position = new Vector2(Position.X, GameClass.Instance.GraphicsDevice.Viewport.Height - 16); IsOnSurface = true; } if (Collision.Collides(BoundingBox, GameClass.Instance.block.BoundingBox)) { Vector2 mtd = Collision.GetMinimumTranslation(BoundingBox, GameClass.Instance.block.BoundingBox); Position += mtd; Velocity.Y = 0; IsOnSurface = true; } if (keyboard.IsKeyDown(Keys.Space) && !previousKeyboard.IsKeyDown(Keys.Space)) { if (IsOnSurface) { Velocity.Y = -jumpHeight; IsOnSurface = false; } } previousKeyboard = keyboard; } This is also a full download to the project. https://www.box.com/s/3rkdtbso3xgfgc2asawy P.S. I know that I could do this with the XNA Platformer Starter Kit algo, but it has some deep flaws that I am going to try to live without. I'd rather go the route of collision response via an overlay function. Thanks for any and all insight!
