  • Semi Fixed-timestep ported to javascript

    - by abernier
    In Gaffer's "Fix Your Timestep!" article, the author explains how to free your physics' loop from the paint one. Here is the final code, written in C: double t = 0.0; const double dt = 0.01; double currentTime = hires_time_in_seconds(); double accumulator = 0.0; State previous; State current; while ( !quit ) { double newTime = time(); double frameTime = newTime - currentTime; if ( frameTime > 0.25 ) frameTime = 0.25; // note: max frame time to avoid spiral of death currentTime = newTime; accumulator += frameTime; while ( accumulator >= dt ) { previousState = currentState; integrate( currentState, t, dt ); t += dt; accumulator -= dt; } const double alpha = accumulator / dt; State state = currentState*alpha + previousState * ( 1.0 - alpha ); render( state ); } I'm trying to implement this in JavaScript but I'm quite confused about the second while loop... Here is what I have for now (simplified): ... (function animLoop(){ ... while (accumulator >= dt) { // While? In a requestAnimation loop? Maybe if? ... } ... // render requestAnimationFrame(animLoop); // stand for the 1st while loop [OK] }()) As you can see, I'm not sure about the while loop inside the requestAnimation one... I thought replacing it with a if but I'm not sure it will be equivalent... Maybe some can help me.

  • Researching runtime technologies (Xmas fun with HTML5)

    - by Eric Nelson
    The Internet Explorer 9.0 team just posted about Pirates love Daises. This is a showcase game for the power of HTML 5 running inside IE 9.0 – and the author has done a fantastic job (you can get more details from Grant’s blog post). A game developer is an ISV (Independent Software Vendor) – a B2C  ISV. In my role I don’t (typically) work with B2C ISVs, hence a reasonable question is “Why blog about it?”. I think applications like this demonstrate the power of HTML 5 and IE9 for delivering really rich user experiences which have the promise of working cross browser and cross platform - in the future as HTML5 capable browsers become the norm. Microsoft is investing heavily in implementing a great “run time” in IE9 if cross platform is an important requirement for your UX. And the other reason for blogging this… it is nearly Xmas and we all should be having a little more fun on the run in. Hence you can play with confidence that your defence to your manager is “I’m just researching a powerful runtime that Microsoft is working on which could be significant to our future B2B product directions” Play now (Needs HTML 5 browser such as IE9) Related Links: To install IE9 Beta or the Preview (which won’t replace your existing IE) check our the IE9 TestDrive center. Learn about our other important UX runtime with the on-demand recordings of the Silverlight FireStarter event.

  • Who writes the words? A rant with graphs.

    - by Roger Hart
    If you read my rant, you'll know that I'm getting a bit of a bee in my bonnet about user interface text. But rather than just yelling about the way the world should be (short version: no UI text would suck), it seemed prudent to actually gather some data. Rachel Potts has made an excellent first foray, by conducting a series of interviews across organizations about how they write user interface text. You can read Rachel's write up here. She presents the facts as she found them, and doesn't editorialise. The result is insightful, but impartial isn't really my style. So here's a rant with graphs. My method, and how it sucked I sent out a short survey. Survey design is one of my hobby-horses, and since some smartarse in the comments will mention it if I don't, I'll step up and confess: I did not design this one well. It was potentially ambiguous, implicitly excluded people, and since I only really advertised it on Twitter and a couple of mailing lists the sample will be chock full of biases. Regardless, these were the questions: What do you do? Select the option that best describes your role What kind of software does your organization make? (optional) In your organization, who writes the text on your software user interfaces? (for example: button names, static text, tooltips, and so on) Tick all that apply. In your organization who is responsible for user interface text? Who "owns" it? The most glaring issue (apart from question 3 being a bit broken) was that I didn't make it clear that I was asking about applications. Desktop, mobile, or web, I wouldn't have minded. In fact, it might have been interesting to categorize and compare. But a few respondents commented on the seeming lack of relevance, since they didn't really make software. There were some other issues too. It wasn't the best survey. So, you know, pinch of salt time with what follows. Despite this, there were 100 or so respondents. This post covers the overview, and you can look at the raw data in this spreadsheet What did people do? Boring graph number one: I wasn't expecting that. Given I pimped the survey on twitter and a couple of Tech Comms discussion lists, I was more banking on and even Content Strategy/Tech Comms split. What the "Others" specified: Three people chipped in with Technical Writer. Author, apparently, doesn't cut it. There's a "nobody reads the instructions" joke in there somewhere, I'm sure. There were a couple of hybrid roles, including Tech Comms and Testing, which sounds gruelling and thankless. There was also, an Intranet Manager, a Creative Director, a Consultant, a CTO, an Information Architect, and a Translator. That's a pretty healthy slice through the industry. Who wrote UI text? Boring graph number two: Annoyingly, I made this a "tick all that apply" question, so I can't make crude and inflammatory generalizations about percentages. This is more about who gets involved in user interface wording. So don't panic about the number of developers writing UI text. First off, it just means they're involved. Second, they might be good at it. What? It could happen. Ours are involved - they write a placeholder and flag it to me for changes. Sometimes I don't make any. It's also not surprising that there's so much UX in the mix. Some of that will be people taking care, and crafting an understandable interface. Some of it will be whatever text goes on the wireframe making it into production. I'm going to assume that's what happened at eBay, when their iPhone app purportedly shipped with the placeholder text "Some crappy content goes here". Ahem. Listing all 17 "other" responses would make this post lengthy indeed, but you can read them in the raw data spreadsheet. The award for the approach that sounds the most like a good idea yet carries the highest risk of ending badly goes to whoever offered up "External agencies using focus groups". If you're reading this, and that actually works, leave a comment. I'm fascinated. Who owned UI text Stop. Bar chart time: Wow. Let's cut to the chase, and by "chase", I mean those inflammatory generalizations I was talking about: In around 60% of cases the person responsible for user interface text probably lacks the relevant expertise. Even in the categories I count as being likely to have relevant skills (Marketing Copywriters, Content Strategists, Technical Authors, and User Experience Designers) there's a case for each role being unsuited, as you'll see in Rachel's blog post So it's not as simple as my headline. Does that mean that you personally, Mr Developer reading this, write bad button names? Of course not. I know nothing about you. It rather implies that as a category, the majority of people looking after UI text have neither communication nor user experience as their primary skill set, and as such will probably only be good at this by happy accident. I don't have a way of measuring those frequency of those accidents. What the Others specified: I don't know who owns it. I assume the project manager is responsible. "copywriters" when they wish to annoy me. the client's web maintenance person, often PR or MarComm That last one chills me to the bone. Still, at least nobody said "the work experience kid". You can see the rest in the spreadsheet. My overwhelming impression here is of user interface text as an unloved afterthought. There were fewer "nobody" responses than I expected, and a much broader split. But the relative predominance of developers owning and writing UI text suggests to me that organizations don't see it as something worth dedicating attention to. If true, that's bothersome. Because the words on the screen, particularly the names of things, are fundamental to the ability to understand an use software. It's also fascinating that Technical Authors and Content Strategists are neck and neck. For such a nascent discipline, Content Strategy appears to have made a mark on software development. Or my sample is skewed. But it feels like a bit of validation for my rant: Content Strategy is eating Tech Comms' lunch. That's not a bad thing. Well, not if the UI text is getting done well. And that's the caveat to this whole post. I couldn't care less who writes UI text, provided they consider the user and don't suck at it. I care that it may be falling by default to people poorly disposed to doing it right. And I care about that because so much user interface text sucks. The most interesting question Was one I forgot to ask. It's this: Does your organization have technical authors/writers? Like a lot of survey data, that doesn't tell you much on its own. But once we get a bit dimensional, it become more interesting. So taken with the other questions, this would have let me find out what I really want to know: What proportion of organizations have Tech Comms professionals but don't use them for UI text? Who writes UI text in their place? Why this happens? It's possible (feasible is another matter) that hundreds of companies have tech authors who don't work on user interfaces because they've empirically discovered that someone else, say the Marketing Copywriter, is better at it. And once we've all finished laughing, I'll point out that I've met plenty of tech authors who just aren't used to thinking about users at the point of need in the way UI text and embedded user assistance require. If you've got what I regard, perhaps unfairly, as the bad kind of tech author - the old-school kind with the thousand-page pdf and the grammar obsession - if you've got one of those then you probably are better off getting the UX folk or the copywriters to do your UI text. At the very least, they'll derive terminology from user research.

  • Is there any reason not to go directly from client-side Javascript to a database?

    - by Chris Smith
    So, let's say I'm going to build a Stack Exchange clone and I decide to use something like CouchDB as my backend store. If I use their built-in authentication and database-level authorization, is there any reason not to allow the client-side Javascript to write directly to the publicly available CouchDB server? Since this is basically a CRUD application and the business logic consists of "Only the author can edit their post" I don't see much of a need to have a layer between the client-side stuff and the database. I would simply use validation on the CouchDB side to make sure someone isn't putting in garbage data and make sure that permissions are set properly so that users can only read their own _user data. The rendering would be done client-side by something like AngularJS. In essence you could just have a CouchDB server and a bunch of "static" pages and you're good to go. You wouldn't need any kind of server-side processing, just something that could serve up the HTML pages. Opening my database up to the world seems wrong, but in this scenario I can't think of why as long as permissions are set properly. It goes against my instinct as a web developer, but I can't think of a good reason. So, why is this a bad idea? EDIT: Looks like there is a similar discussion here: Writing Web "server less" applications EDIT: Awesome discussion so far, and I appreciate everyone's feedback! I feel like I should add a few generic assumptions instead of calling out CouchDB and AngularJS specifically. So let's assume that: The database can authenticate users directly from its hidden store All database communication would happen over SSL Data validation can (but maybe shouldn't?) be handled by the database The only authorization we care about other than admin functions is someone only being allowed to edit their own post We're perfectly fine with everyone being able to read all data (EXCEPT user records which may contain password hashes) Administrative functions would be restricted by database authorization No one can add themselves to an administrator role The database is relatively easy to scale There is little to no true business logic; this is a basic CRUD app

  • Using XML as data storage

    - by Kian Mayne
    I was thinking about the XML format and the following quote: “XML is not a database. It was never meant to be a database. It is never going to be a database. Relational databases are proven technology with more than 20 years of implementation experience. They are solid, stable, useful products. They are not going away. XML is a very useful technology for moving data between different databases or between databases and other programs. However, it is not itself a database. Don't use it like one.“ -Effective XML: 50 Specific Ways to Improve Your XML by Elliotte Rusty Harold (page 230, Part 4, Item 41, 2nd paragraph) This seems to really stress that XML should not be used for data storage and should only be used for program to program interoperability. Personally, I disagree and .NET's app.config file that's used to store a program's settings is an example of data storage in an XML file. However for databases rather than configurations etc XML should not be used. To develop my point, I will use two examples: A) Data about customers with fields that are all on one level i.e. there are a number of fields all relating to one customer with no children B) Data about configuration of an application where nested fields and properties make a lot of sense So my question is, Is this still a valid statement and is it now acceptable to store data using XML? EDIT: I've sent an email to the author of that quote to ask for his input/extra context.

  • Can I re-license Academic Free License code under 2-Clause BSD / ITC?

    - by Stefano Palazzo
    I want to fork a piece of code licensed under the Academic Free License. For the project, it would be preferable to re-license it under the ISC License or the 2-Clause BSD license, which are equivalent. I understand that the AFL grants me things such as limitation of liability, but licensing consistency is much more important to the project, especially since we're talking about just 800 lines of code, a quarter of which I've modified in some way. And it's very important for me to give these changes back to the community, given the fact that this is software relevant to security - I need the public scrutiny that I'll get by creating a public fork. In short: At the top of the file I want to say this, or something like it: # Licensed under the Academic Free License, version 3 # Copyright (C) 2009 Original Author # Licensed under the ISC License # Copyright (C) 2012 Stefano Palazzo # Copyright (C) 2012 Company Am I allowed to do this? My research so far indicates that it's not clear whether the AFL is GPL-Compatible, and I can't really understand any of the stuff concerning re-licensing to other permissive licenses. As a stop gap, I would also be okay with re-licensing under the GPL, however: I can find no consensus (though I can find disagreement) on whether this is allowed at all, and I don't want to risk it, of course.

  • Strict Pomodoro and other time management Chrome extensions

    - by kerry
    I have recently begun using the Pomodoro Technique to increase my productivity. However, I still find myself getting sucked in to the vortex of useless information that is the internet. With that in mind I began searching for a useful chrome extension to replace the Android Pomodoro app I have been using to manage my ‘doros. I even considered writing it myself. Luckily, I stumbled on one that had a similar featureset to what I was looking for. Strict Pomodoro is an excellent Chrome extension for practicing Pomodoro. Though lacking a few key features, such as the ability to set the duration of your pomodoros and breaks, it still has a key feature that helps me stay on task. It blocks time sucking websites. You can set filter lists and it will keep you from accessing them during a Pomodoro. Effectively reminding you to stay on task. Also, the author readily admits that it was quickly put together and new features may be added down the road. For now, it is still an excellent option. For those of you who do not practice Pomodoro but are trying to stay on task. The StayFocusd extension will effectively manage the amount of time you spend on useless (non-productive) sites. It also has a rich feature set that may be better for your work habits. OK, breaks over. Time to get back to work. 25 minutes at a time.

  • Getting codebaseHQ SVN ChangeLog data in your application

    - by saifkhan
    I deploy apps via ClickOnce. After each deployment we have to review the changes made and send out an email to the users with the changes. What I decided now to do is to use CodebaseHQ’s API to access a project’s SVN repository and display the commit notes so some users who download new updates can check what was changed or updated in an app. This saves a heck of a lot of time, especially when your apps are in beta and you are making several changes daily based on feedback. You can read up on their API here Here is a sample on how to access the Repositories API from a windows app Public Sub GetLog() If String.IsNullOrEmpty(_url) Then Exit Sub Dim answer As String = String.Empty Dim myReq As HttpWebRequest = WebRequest.Create(_url) With myReq .Headers.Add("Authorization", String.Format("Basic {0}", Convert.ToBase64String(Encoding.ASCII.GetBytes("username:password")))) .ContentType = "application/xml" .Accept = "application/xml" .Method = "POST" End With Try Using response As HttpWebResponse = myReq.GetResponse() Using sr As New System.IO.StreamReader(response.GetResponseStream()) answer = sr.ReadToEnd() Dim doc As XDocument = XDocument.Parse(answer) Dim commits = From commit In doc.Descendants("commit") _ Select Message = commit.Element("message").Value, _ AuthorName = commit.Element("author-name").Value, _ AuthoredDate = DateTime.Parse(commit.Element("authored-at").Value).Date grdLogData.BeginUpdate() grdLogData.DataSource = commits.ToList() grdLogData.EndUpdate() End Using End Using Catch ex As Exception MsgBox(ex.Message) End Try End Sub

  • Explanation on how "Tell, Don't Ask" is considered good OO

    - by Pubby
    This blogpost was posted on Hacker News with several upvotes. Coming from C++, most of these examples seem to go against what I've been taught. Such as example #2: Bad: def check_for_overheating(system_monitor) if system_monitor.temperature > 100 system_monitor.sound_alarms end end versus good: system_monitor.check_for_overheating class SystemMonitor def check_for_overheating if temperature > 100 sound_alarms end end end The advice in C++ is that you should prefer free functions instead of member functions as they increase encapsulation. Both of these are identical semantically, so why prefer the choice that has access to more state? Example 4: Bad: def street_name(user) if user.address user.address.street_name else 'No street name on file' end end versus good: def street_name(user) user.address.street_name end class User def address @address || NullAddress.new end end class NullAddress def street_name 'No street name on file' end end Why is it the responsibility of User to format an unrelated error string? What if I want to do something besides print 'No street name on file' if it has no street? What if the street is named the same thing? Could someone enlighten me on the "Tell, Don't Ask" advantages and rationale? I am not looking for which is better, but instead trying to understand the author's viewpoint.

  • Programming in academic environment vs industry environment [closed]

    - by user200340
    Possible Duplicate: Differences between programming in school vs programming in industry? This is a general discussion about programming in the industry environment. The background story is that my colleague sent me a very interesting article called "10 Things Entrepreneurs Don’t Learn in College." The first point in that post is about the author's experience of programming in the academic environment vs industry environment. After finishing a 4 year Computer Science degree course, I am currently working in the academic environment as a developer, mainly writing Java, J2EE, Javascript code. I know there are differences between academic programming and industry programming, but I was shocked after reading that post. Trying to avoid this happening on me in the future, or the others. Can anyone from industry give some general advice about how to program in industry. For example, What exactly happens when a task is received? What is the flow from the beginning to the end? What are the main differences between the programming in industry and academia? Is it more structured? Are more frameworks used? It would be great if some code examples could be given. Thanks.

  • Has anyone else read "Programming video games for the Evil Genius"

    - by Martin
    I bought this book called "Programming Video Games for the Evil Genius" by Ian Cinnamon. If there is anyone who has read or is familiar with this book I am wondering if they think it is worth reading. I am interested in making video games. I have already taken intro courses in C++, Java and Python and got through okay. I've been going through this book for about a month now(SLOWLY). All I have to do is type the code exactly in the book, BUT a lot of the code is not clearly explained. I do some research online but I usually still have some trouble answering my questions. Then I found stack overflow. It's been a ton of help. Right now I am trying to make a racing game right out of this book and I got to a point where the author left a bunch of errors in his code. One of the members of this website fixed it up for me, but added some stuff that I'm having trouble understanding. I spend more time trying to figure out the authors errors and fix them or get someone to help me fix them than I actually do learning code. I REALLY want to learn how to do this and I am ready and willing to put in the time, but I'm not sure if my time would be better spent learning from a different source. Are there any veterans out there that are familiar with this book and think it's worth it/not worth it? Should I try to move onto another book?

  • Unexpected issues with SessionPageStatePersiste

    - by geekrutherford
    Several iterations ago I implemented the SessionPageStatePersister in an application as a way to cut down on the size of the hidden ViewState input on aspx pages.   At first it seemed utterly fantasic. The size of the ViewState appeared to be drastically reduced and the application did not appear to peform any slower than baseline.   Enter the iFrame &amp; user control. I added a user control which pings the web server every 20 seconds in order to show updated application information to the user (new messages, reports, etc.) After releasing this nifty little control into the QA environment I quickly began receiving emails from testers about "post back" related error messages which mostly centered around invalid ViewState exceptions.   At first I dismissed it as something related to all of the AJAX requests happening on the page and considered turning off page event validation. However, upon further investigation I came across the following article:   Things That You Should Watch Out For When Using SessionPageStatePersister   In this article the author specifically states:   If you application uses frames than each frame request will create a new session view state item and as before it will remove items when reaching the maximum, you come into a situation that one of the frames will probably loose it session view state because other frames did post backs.   Oh snap! That is precisely what I am doing. That combined with multiple users on the application equals dropped ViewStates!   The temporary fix has been to disable the use of the SessionPageStatePersister in my application. This results in a bloated hidden ViewState input, but the web server is no longer tasked with maintaing/retreiving it and the app. no longer loses ViewState information.

  • Junior developer introduction to job industry

    - by lady_killer
    I am a junior developer at my second working experience, the first one using PHP with WordPress and currently on Groovy on Grails. I like coding, I attend meetup to discuss technology etc but I still did not understand how to become a real professional with the "know how" attitude. I read Clean Coder, the author advises to spend 20 hours per week of my spare time to learn new technologies and to keep myself up to date. I do not find this realistic, if you want to have a bit of a social life, and I also noticed that learning at work, at least in the places where I worked, is not ideal. No support from seniors for new projects, no pair programming and code reviews, no company trainings, one hour a week tech meetings where seniors walk away after a bit because they already know the topic discussed and so on. Sometimes is quite hard to keep the motivation... My questions are: Is our industry supposed to be like this? Is there real team working in the sense of sharing knowledge and help juniors to get up to speed? Are we supposed to learn new technologies or technology features just in our spare time?Clean Coder says football players do not train during official matches and our working hours are like official matches, we should just perform and learn in other moments. Is it really like this? How can I improve my skills with no support? Is it enough to read books and try out the exercises and perhaps some katas? In almost 5 month of Groovy on Grails experience at work, I have never had the opportunity to create anything from scratch, just worked on existing issues where it was even really difficult to get the domain knowledge from senior devs.

  • Plastic Clamshell Packaging Voted Worse Design Ever

    - by Jason Fitzpatrick
    We’ve all been there: frustrated and trying free a new purchase from it’s plastic clamshell jail. You’re not alone, the packaging design has been voted the worst in history. In a poll at Quora, users voted on the absolute worst piece of design work they’d encountered. Overwhelmingly, they voted the annoying-to-open clamshell design to the top. The author of the top comment/entry, Anita Shillhorn writes: “Design should help solve problems” — clamshells are supposed to make it harder to steal small products and easier for employees to arrange on display — but this packaging, she says, makes new ones, such as time wasted, frustration, and the little nicks and scrapes people incur as they just try to get their damn lightbulb out. This is a product designed for the manufacturers and the retailers, not the end users. There is even a Wikipedia page devoted to “wrap rage,” “the common name for heightened levels of anger and frustration resulting from the inability to open hard-to-remove packaging.” Hit up the link below for more entries in their worst-design poll. Before you go, if you’ve got a great tip for getting goods out of the plastic shell they ship in, make sure to share it in the comments. What Is The Worst Piece of Design Ever Done?
