  • What is the most performant CSS property for transitioning an element?

    - by Ian Kuca
    I'm wondering whether there is a performance difference between using different CSS properties to translate an element. Some properties fit different situations differently. You can translate an element with following properties: transform, top/left/right/bottom and margin-top/left/right/bottom In the case where you do not utilize the transition CSS property for the translation but use some form of a timer (setTimeout, requestAnimationFrame or setImmediate) or raw events, which is the most performant–which is going to make for higher FPS rates?

  • On what basis would you split donation money among your open source team members without any strife?

    - by Vigneshwaran
    I am a developer of an open source project which is hosted in SourceForge. It started out as a little app then after some releases, it got more and more popular and it started consuming more time and responsibility from me. So I have enabled the donation option in SourceForge. I'm passionate to continue developing it for free but if (ever) any money comes in, how should I split it with my team? Should I split the amount equally among the number of team members? (50-50 as it is two-member team now) Number of classes, commits or any other valuable submissions by team members? Any other idea? What would you do in such situation? Please give your opinions. I hope this question will be useful for others.

  • Resources for using TFS for Agile Project Development?

    - by Amy P
    Our company just installed TFS for us to start using for project development processes and source control. They want us to start using it to manage our projects as well. We have a small team, no current bug or task tracking software, and 2 developers of the 3 have experience with any actual methodologies. What books, websites, and/or other information can you recommend for us to use to get started?

  • Is there a real difference between dynamic analysis and testing?

    - by user970696
    Often testing is regarded as a dynamic analysis of a software. Yet while writing my thesis, the reviewer noted to me that dynamic analysis is about analyzing the program behind the scenes - e.g. profiling and that it is not the same as testing because its "analysis" which looks inside and observes. I know that "static analysis" is not testing, should we then separate this "dynamic analysis" also from testing? Some books do refer to dynamic analysis in this sense. I would maybe say that testing is a one mean of dynamic analysis?

  • OpenGL programming vs Blender Software, which is better for custom video creation?

    - by iammilind
    I am learning OpenGL API bit by bit and also develop my own C++ framework library for effectively using them. Recently came across Blender software which is used for graphics creation and is in turn written in OpenGL itself. For my part time hobby of graphics learning, I want to just create small-small movie or video segments; e.g. related to construction engineering, epic stories and so on. There may be very minimal to nil mouse-keyboard interaction for those videos, unlike video games which are highly interactive. I was wondering if learning OpenGL from scratch is worth for it or should I invest my time in learning Blender software? There are quite a few good movie examples are created using Blender and are shown in its website. Other such opensource cross platform alternatives are also welcome, which can serve my aforementioned purpose.

  • Count unique visitors by group of visited places

    - by Mathieu
    I'm facing the problem of counting the unique visitors of groups of places. Here is the situation: I have visitors that can visit places. For example, that can be internet users visiting web pages, or customers going to restaurants. A visitor can visit as much places as he wishes, and a place can be visited by several visitors. A visitor can come to the same place several times. The places belong to groups. A group can obviously contain several places, and places can belong to several groups. Given that, for each visitor, we can have a list of visited places, how can I have the number of unique visitors per group of places? Example: I have visitors A, B, C and D; and I have places x, y and z. I have these visiting lists: [ A -> [x,x,y,x], B -> [], C -> [z,z], D -> [y,x,x,z] ] Having these number of unique visitors per place is quite easy: [ x -> 2, // A and D visited x y -> 2, // A and D visited y z -> 2 // C and D visited z ] But if I have these groups: [ G1 -> [x,y,z], G2 -> [x,z], G3 -> [x,y] ] How can I have this information? [ G1 -> 3, // A, C and D visited x or y or z G2 -> 3, // A, C and D visited x or z G3 -> 2 // A and D visited x or y ] Additional notes : There are so many places that it is not possible to store information about every possible group; It's not a problem if approximation are made. I don't need 100% precision. Having a fast algorithm that tells me that there were 12345 visits in a group instead of 12543 is better than a slow algorithm telling the exact number. Let's say there can be ~5% deviation. Is there an algorithm or class of algorithms that addresses this type of problem?

  • Visual Studio 2010 editor painfully slow

    - by Daniel Gehriger
    I'm running out of patience with MS VisualStudio 2010: I'm working on a solution containing ~50 C++ projects. When using the editor, I experience a lag of 1 - 2 seconds whenever I move the cursor to a different line, or when I move to a different window, or generally when the editor losses and gains focus. I went through a whole series of optimizations, to no avail: installed all hotfixes for VS2010 disabled all add-ins and extensions disabled Intellisense deleted all temporary files created by VS2010 disabled hardware acceleration unloaded all but 15 projects disabled tracking changes closed all but one window and so on. This is on a Dual Core machine with SSD harddrive (verified throughput 100MB/s), enough free space on HD, Windows 7 Pro 32-bit with 3GB of RAM and most of it still free. Whenever I type a letter, CPU usage of devenv.exe goes to 50 - 90% in process monitor for 1 - 2 seconds before returning to 5%. I used Process Explorer to analyze registry and file system access, and I only notice frequent accesses to the .sln file (which is quiet small), and a few registry reads, but nothing that would raise a red flag. I don't have this problem with solutions containing less projects, so I'm inclined to think that it's related to the number of projects. For your information, the entire solution has been migrated over the years from VS2005 to VS2008 to now VS2010. Does anyone have any ideas what else I could do to resume work on this project, other than returning to VS2008?

  • using a wiki for requirements

    - by apollodude217
    Hi, I'm looking into ways of improving requirements management. Currently, we have a Word document published on a Web site. Unfortunately, we cannot (to my knowledge) look at changes from one revision to the next. I would greatly prefer to be able to do so, much like with a wiki or VCS (or both, like the wiki's on bitbucket!). Also, each document describes changes devs are expected to meet by a given deadline. There is no collection of accumulated app features documented anywhere, so it's sometimes hard to distinguish between a bug and a (poorly-designed) feature when trying to make quick fixes to legacy apps. So I had an idea I wanted to get feedback on. What about: Using a wiki so that we can track who changed what when (mostly to even see if any edits were made since the last time one looked). Having one, say, wiki page per product rather than one per deadline, keeping up with all features of the product rather than the changes that should be implemented. This way, I can look at a particular revision of the page to see what the app should do at a given point in time, and I can look at changes to the page since the last release for the requirements to be implemented by the next deadline. Waddayathink?

  • should i take Exam 70-515 or should i wait for Exam 70-480 ? [closed]

    - by Filip
    As it states on Microsoft site exam 70-515 is scheduled to retire July 31, 2013. His successor is suppose to be exam 70-480 in my understanding. I know most of the stuff in exam 70-515 but it will take me like one mount to read the book from Microsoft Press Resource Center and get ready for the exam, also i will be paying for the exam not the company i work for. So i think it is better to start reading books and forums that concentrate on how and for what will be exam 70-480 then paying for something that will not be valued for ~ 1 year from now. Whats your thoughts/suggestions ?

  • How forgiving do you need to be on new employees?

    - by Arcturus
    Recently we have a new developer in our team. We are getting him up to speed and he is picking it all up quite fast, but a new developer means new (foreign) coding styles and ways to solve things. It feels kinda petty to start whining about coding styles at the first three classes he codes, but how forgiving are you guys when dealing with new developers? Do you let them muddle on, and point it out later? Or do you wield the scepter of intolerance immediately? When do you draw the line, or if not, why not? P.S. New guy, if you read this: you are doing great, keep up the good work ;) Edit: I've accepted the most up-voted answer, as most answers share the same message: Be nice, but tell them asap! Thanks all for the nice answers! Really appreciated it!

  • Who should write the test plan?

    - by Cheng Kiang
    Hi, I am in the in-house development team of my company, and we develop our company's web sites according to the requirements of the marketing team. Before releasing the site to them for acceptance testing, we were requested to give them a test plan to follow. However, the development team feels that since the requirements came from the requestors, they would have the best knowledge of what to test, what to lookout for, how things should behave etc and a test plan is thus not required. We are always in an argument over this, and developers find it a waste of time to write down things like:- Click on button A. Key in XYZ in the form field and click button B. You should see behaviour C. which we have to repeat for each requirement/feature requested. This is basically rephrasing what's already in the requirements document. We are moving towards using an Agile approach for managing our projects and this is also requested at the end of each iteration. Unit and integration testing aside, who should be the one to come up with the end user acceptance test plan? Should it be the reqestors or the developers? Many thanks in advance. Regards CK

  • When connecting to a server using the DRDA protocol, is it true that the first Client-To-Server command MUST be EXCSAT chained with ACCSEC?

    - by Alon Rew
    When connecting to a server using the DRDA protocol, is it true that the first Client-To-Server command MUST be EXCSAT chained with ACCSEC? I found 2 different answers when I googled it. If you look at The Open Group web site (https://collaboration.opengroup.org/dbiop/) it can be understood that the answer is NO. However, if you look at the IBM website (http://publib.boulder.ibm.com/infocenter/dzichelp/v2r2/index.jsp?topic=%2Fcom.ibm.ims11.doc.apr%2Fims_ddm_excsat.htm) you can understand the answer is YES. So which is it?

  • How can test users access an unpublished iOS app?

    - by David
    I am considering outsourcing the development of an iOS app to various independent developers. I will have have various testers of the app. We all work for separate companies. Some of these testers will be customers, who I would like feedback from. As there are multiple developers involved I expect there to be a new release on a daily basis. How can this be done? Would each of the testers need to buy some sort of license to avoid having to go through the app approval process? Is there any smooth way to do this so that it will not be a hassle for our friendly customers, who are willing to test our app?

  • Starting an HTML canvas game with no graphics skills

    - by Jacob
    I want to do some hobby game development, but I have some unfortunate handicaps that have me stuck in indecision; I have no artistic talent, and I also have no experience with 3D graphics. But this is just a hobby project that might not go anywhere, so I want to develop the stuff I care about; if the game shows good potential, my graphic "stubs" can be replaced with something more sophisticated. I do, however, want my graphics engine to render something approximate to the end goal. The game is tile-based, with each tile being a square. Each tile also has an elevation. My target platform (subject to modification) is JavaScript rendering to the HTML 5 canvas, either with a 2D or WebGL context. My question to those of you with game development experience is whether it's easier to develop an isometric game using a 2D graphics engine and sprites or a 3D game using rudimentary 3D primitives and basic textures? I realize that there are limitations to isometric projection, but if it makes developing my throwaway graphics engine easier, I'm OK with the visual warts that would be introduced. Or is representing a 3D world with an actual 3D engine easier?

  • Node.js Or servlets?

    - by Nilesh
    I have heard a lot and read about the Javascript server side language i.e Node.js, and saw many comparisons in favor of Node. I don't understand what makes it better or faster, or how it even relates to something as mature as Java Servlets. But Servlets are built on top of a multithreaded programming language as opposed to Node.js. Then how can node.js be faster? If suppose 1000K users query for a database records, then shouldn't Node.js be slower than Servlets. Also Don't servlets have better security compared to Node.js?

  • Should a poll framework be closed sourced

    - by samquo
    I was having a chat with a coworker who is working on a polling app and framework. He was asking technical questions and I suggested he open source the application to get more quality opinions from developers who are interested in this problem and are willing to give it heavy though. He has a different point of view which I think is still valid so I want to open this question for discussion here. He says he believes something like a polling framework should not be open sourced because it will reduce its security and validity as people reveal loopholes through which they can cheat. Can't say I completely disagree. I see a somewhat valid point there, but I always believed that solutions by a group of people are almost always better than a solution thought by a single person asking a small number of coworkers, no matter how smart that person is. Again I'm willing to accept that maybe some types of applications are different. Does anyone have an argument in his favor? I'd really like to present your responses to him.

  • What is your strategy for converting RC builds into retail?

    - by Matthew PK
    We're trying to implement a strategy for how we transition our builds from RC to released retail code. When we label a build as a release candidate, we send it to QA for regression. If they approve it, that RC then becomes our released retail code. I liked the idea of "obvious" labeling of versions so that a user knows whether they have a beta or an RC or retail code... where you would have some obvious watermark in non-retail code (think Windows 7 where the RC or non-genuine builds watermark in the bottom right). ... but it seemed strange to us to manipulate the project (to remove the watermark) once it passed regression. If QA certified version a.b.c.d then our retail code should be that same version, not a.b.c.d+1 what strategies have you employed to clearly label non-release software versions without incrementing your build to disable the watermarks in your retail code? One idea I've considered is writing your build to look for a signed file in the installer archive... non-release code wouldn't include this file and so the app would know to display a watermark. But even this seems like QA is then working with non-release code. Ideas?

  • Multi-platform Map Application

    - by Mahdi
    I'm working on a web project (PHP, jQuery) which currently using Google Maps powering up the map functionality of the application, however we need to make it multi-platform like you can go to the dashboard and choose one from 5-10 map providers (which Goolge Maps is just one of them) to underlying your map functionality. So, as the application is supposed to show the data on map, almost in every single place we have to deal with the API provided by that specific map provider. Currently we are thinking about revising our modular structure and/or making something like an adapter for each provider to deal with their native syntax but via our standard methods. I wish to have your ideas and your experiences, specially if you ever made an interface for dealing via 2-3 different map providers. That would helps much and I really appreciate that. If you need any further information, just ask me to update the question. Update: As Vicky Chijwani suggested Mapstraction, now I'm also wondering which one is more better (pros & cons), having an adapter implemented on Javascript or PHP?

  • Help to understand the abstract factory pattern

    - by Chobeat
    I'm learning the 23 design patterns of the GoF. I think I've found a way to understand and simplify how the Abstract Factory works but I would like to know if this is a correct assumption or if I am wrong. What I want to know is if we can see the result of the Abstract Factory method as a matrix of possible products where there's a Product for every "Concrete Factory" x "AbstractProduct" where the Concrete Factory is a single implementation among the implementations of an AbstractFactory and an AbstractProduct is an interface among the interfaces to create Products. Is this correct or am I missing something?

  • What good books are out there on program execution models? [on hold]

    - by murungu
    Can anyone out there name a few books that address the topic of program execution models?? I want a book that can answer questions such as... What is the difference between interpreted and compiled languages and what are the performance consequences at runtime?? What is the difference between lazy evaluation, eager evaluation and short circuit evaluation?? Why would one choose to use one evaluation strategy over another?? How do you simulate lazy evaluation in a language that favours eager evaluation??

  • Vector with Constant-Time Remove - still a Vector?

    - by Darrel Hoffman
    One of the drawbacks of most common implementations of the Vector class (or ArrayList, etc. Basically any array-backed expandable list class) is that their remove() operation generally operates in linear time - if you remove an element, you must shift all elements after it one space back to keep the data contiguous. But what if you're using a Vector just to be a list-of-things, where the order of the things is irrelevant? In this case removal can be accomplished in a few simple steps: Swap element to be removed with the last element in the array Reduce size field by 1. (No need to re-allocate the array, as the deleted item is now beyond the size field and thus not "in" the list any more. The next add() will just overwrite it.) (optional) Delete last element to free up its memory. (Not needed in garbage-collected languages.) This is clearly now a constant-time operation, since only performs a single swap regardless of size. The downside is of course that it changes the order of the data, but if you don't care about the order, that's not a problem. Could this still be called a Vector? Or is it something different? It has some things in common with "Set" classes in that the order is irrelevant, but unlike a Set it can store duplicate values. (Also most Set classes I know of are backed by a tree or hash map rather than an array.) It also bears some similarity to Heap classes, although without the log(N) percolate steps since we don't care about the order.

  • Common Javascript mistakes that severely affect performance?

    - by melee
    At a recent UI/UX MeetUp that I attended, I gave some feedback on a website that used Javascript (jQuery) for its interaction and UI - it was fairly simple animations and manipulation, but the performance on a decent computer was horrific. It actually reminded me of a lot of sites/programs that I've seen with the same issue, where certain actions just absolutely destroy performance. It is mostly in (or at least more noticeable in) situations where Javascript is almost serving as a Flash replacement. This is in stark contrast to some of the webapps that I have used that have far more Javascript and functionality but run very smoothly (COGNOS by IBM is one I can think of off the top of my head). I'd love to know some of the common issues that aren't considered when developing JS that will kill the performance of the site.

  • What would be the best approach to make revisions of user content?

    - by Kevin Simper
    I have searched and could not find any information about it. What is the best approach to storing revisions? I have a website where the user can write a document which can be fairly long (200-300 lines). How do you determine when to make a revision? Is it not a scalable solution to make a new one whenever the save, because that would be useless to the user when the want to look back, and it would require quite a lot of space. You could use time and say for every 15 minute they are working on it there would be a revision, but that would sometimes be nothing or the whole document have completely changed. I could make a diff from the previous revision, and compare by line and look at how many percent of the lines have been changed. What are other doing revisions?

  • How Did we get from CLI to Graphics?

    - by Nathaniel Bennett
    I'm confused when looking into graphics - specifically with operating systems. I mean, how can a computer render a CLI/console along with a GUI. GUI's are completely different from Text. and How Can we have GUI windows that Display Text interfaces, ie how can we have CLI in modern Graphics Operating system - that's what I'm mainly trying to grip on to. How Do Graphic's get rendered to display? is there some sort of memory address that a GPU access which holds all pixel data, and there system's within OS's that Gather the pixel position of Windows and Widgets, along with the Z Index and rasterize them to that memory address, which then the GPU loads to the screen? How About the CLI's integrated with Graphics? how does the OS Tell the GPU that a certain part of the screen wants to display text while the rest, whats to display pixel data? it's all very confusing. Shed some light in it, will ya?
