• Interpolating Matrices

  - by sebf

  Hello, Apologies if I am missing something very obvious (likely!) but is there anything wrong with interpolating between two matrices by: float d = (float)(targetTime.Ticks - keyframe_start.ticks) / (float)(keyframe_end.ticks - keyframe_start.ticks); return ((keyframe_start.Transform * (1 - d)) + (keyframe_end.Transform * d)); As in my app, when I try an use this to interpolate between two keyframes, the model begins to 'shrink' - the severity based on how far between the two keyframes the target time is; its worst when the transform split is ~50/50.

• Transparent Technology from Amazon

  - by David Dorf

  Amazon has been making some interesting moves again, this time in the augmented humanity area.  Augmented humanity is about helping humans overcome their shortcomings using technology.  Putting a powerful smartphone in your pocket helps you in many ways like navigating streets, communicating with far off friends, and accessing information.  But the interface for smartphones is somewhat limiting and unnatural, so companies have been looking for ways to make the technology more transparent and therefore easier to use. When Apple helped us drop the stylus, we took a giant leap forward in simplicity.  Using touchscreens with intuitive gestures was part of the iPhone's original appeal.  People don't want to know that technology is there -- they just want the benefits.  So what's the next leap beyond the touchscreen to make smartphones even easier to use? Two natural ways we interact with the world around us is by using sight and voice.  Google and Apple have been using both in their mobile platforms for limited uses cases.  Nobody actually wants to type a text message, so why not just speak it?  Any if you want more information about a book, why not just snap a picture of the cover?  That's much more accurate than trying to key the title and/or author. So what's Amazon been doing?  First, Amazon released a new iPhone app called Flow that allows iPhone users to see information about products in context.  Yes, its an augmented reality app that uses the phone's camera to view products, and overlays data about the products on the screen.  For the most part it requires the barcode to be visible to correctly identify the product, but I believe it can also recognize certain logos as well.  Download the app and try it out but don't expect perfection.  Its good enough to demonstrate the concept, but its far from accurate enough.  (MobileBeat did a pretty good review.)  Extrapolate to the future and we might just have a heads-up display in our eyeglasses. The second interesting area is voice response, for which Siri is getting lots of attention.  Amazon may have purchased a voice recognition company called Yap, although the deal is not confirmed.  But it would make perfect sense, especially with the Kindle Fire in Amazon's lineup. I believe over the next 3-5 years the way in which we interact with smartphones will mature, and they will become more transparent yet more important to our daily lives.  This will, of course, impact the way we shop, making information more readily accessible than it already is.  Amazon seems to be positioning itself to be at the forefront of this trend, so we should be watching them carefully.

• Android, how important is deltaTime?

  - by iQue

  Im making a game that is getting pretty big and sometimes my thread has to skip a frame, so far I'm not using deltaTime for setting the speed of my different objects in the game because it's still not a big enough game for it to matter imo. But its getting bigger then I planned, so my question is, how important is delta Time? If I should use delta time there is a problem, since speedX and speedY are integers(they have to be for eclipse to let you make a rectangle of them), I cant add delta time very functionally as far as I understand, but might be wrong? Ive tried adding deltaTime to the code below, and sometimes my enemies just not move after spawn, they just stand there and run in the same place Will add an some code for how I set / use speed: public void update(int dx, int dy) { double theta = 180.0 / Math.PI * Math.atan2(-(y - controls.pointerPosition.y), controls.pointerPosition.x - x); x +=dx * Math.cos(Math.toRadians(theta)); y +=dy * Math.sin(Math.toRadians(theta)); currentFrame = ++currentFrame % BMP_COLUMNS; } public void draw(Canvas canvas) { int srcX = currentFrame * width; int srcY = 1 * height; Rect src = new Rect(srcX, srcY, srcX + width, srcY + height); Rect dst = new Rect(x, y, x + width, y + height); canvas.drawBitmap(bitmap, src, dst, null); } So if someone with some experience with this has any thoughts, please share. Thank you! Changed code: public void update(int dx, int dy, float delta) { double theta = 180.0 / Math.PI * Math.atan2(-(y - controls.pointerPosition.y), controls.pointerPosition.x - x); double speedX = delta * dx * Math.cos(Math.toRadians(theta)); double speedY = delta * dy * Math.sin(Math.toRadians(theta)); x += speedX; y += speedY; currentFrame = ++currentFrame % BMP_COLUMNS; } public void draw(Canvas canvas) { int srcX = currentFrame * width; int srcY = 1 * height; Rect src = new Rect(srcX, srcY, srcX + width, srcY + height); Rect dst = new Rect(x, y, x + width, y + height); canvas.drawBitmap(bitmap, src, dst, null); } with this code my enemies move like before, except they wont move to the right (wont increment x), all other directions work.

• The Great Divorce

  - by BlackRabbitCoder

  I have a confession to make: I've been in an abusive relationship for more than 17 years now.  Yes, I am not ashamed to admit it, but I'm finally doing something about it. I met her in college, she was new and sexy and amazingly fast -- and I'd never met anything like her before.  Her style and her power captivated me and I couldn't wait to learn more about her.  I took a chance on her, and though I learned a lot from her -- and will always be grateful for my time with her -- I think it's time to move on. Her name was C++, and she so outshone my previous love, C, that any thoughts of going back evaporated in the heat of this new romance.  She promised me she'd be gentle and not hurt me the way C did.  She promised me she'd clean-up after herself better than C did.  She promised me she'd be less enigmatic and easier to keep happy than C was.  But I was deceived.  Oh sure, as far as truth goes, it wasn't a complete lie.  To some extent she was more fun, more powerful, safer, and easier to maintain.  But it just wasn't good enough -- or at least it's not good enough now. I loved C++, some part of me still does, it's my first-love of programming languages and I recognize its raw power, its blazing speed, and its improvements over its predecessor.  But with today's hardware, at speeds we could only dream to conceive of twenty years ago, that need for speed -- at the cost of all else -- has died, and that has left my feelings for C++ moribund. If I ever need to write an operating system or a device driver, then I might need that speed.  But 99% of the time I don't.  I'm a business-type programmer and chances are 90% of you are too, and even the ones who need speed at all costs may be surprised by how much you sacrifice for that.   That's not to say that I don't want my software to perform, and it's not to say that in the business world we don't care about speed or that our job is somehow less difficult or technical.  There's many times we write programs to handle millions of real-time updates or handle thousands of financial transactions or tracking trading algorithms where every second counts.  But if I choose to write my code in C++ purely for speed chances are I'll never notice the speed increase -- and equally true chances are it will be far more prone to crash and far less easy to maintain.  Nearly without fail, it's the macro-optimizations you need, not the micro-optimizations.  If I choose to write a O(n2) algorithm when I could have used a O(n) algorithm -- that can kill me.  If I choose to go to the database to load a piece of unchanging data every time instead of caching it on first load -- that too can kill me.  And if I cross the network multiple times for pieces of data instead of getting it all at once -- yes that can also kill me.  But choosing an overly powerful and dangerous mid-level language to squeeze out every last drop of performance will realistically not make stock orders process any faster, and more likely than not open up the system to more risk of crashes and resource leaks. And that's when my love for C++ began to die.  When I noticed that I didn't need that speed anymore.  That that speed was really kind of a lie.  Sure, I can be super efficient and pack bits in a byte instead of using separate boolean values.  Sure, I can use an unsigned char instead of an int.  But in the grand scheme of things it doesn't matter as much as you think it does.  The key is maintainability, and that's where C++ failed me.  I like to tell the other developers I work with that there's two levels of correctness in coding: Is it immediately correct? Will it stay correct? That is, you can hack together any piece of code and make it correct to satisfy a task at hand, but if a new developer can't come in tomorrow and make a fairly significant change to it without jeopardizing that correctness, it won't stay correct. Some people laugh at me when I say I now prefer maintainability over speed.  But that is exactly the point.  If you focus solely on speed you tend to produce code that is much harder to maintain over the long hall, and that's a load of technical debt most shops can't afford to carry and end up completely scrapping code before it's time.  When good code is written well for maintainability, though, it can be correct both now and in the future. And you know the best part is?  My new love is nearly as fast as C++, and in some cases even faster -- and better than that, I know C# will treat me right.  Her creators have poured hundreds of thousands of hours of time into making her the sexy beast she is today.  They made her easy to understand and not an enigmatic mess.  They made her consistent and not moody and amorphous.  And they made her perform as fast as I care to go by optimizing her both at compile time and a run-time. Her code is so elegant and easy on the eyes that I'm not worried where she will run to or what she'll pull behind my back.  She is powerful enough to handle all my tasks, fast enough to execute them with blazing speed, maintainable enough so that I can rely on even fairly new peers to modify my work, and rich enough to allow me to satisfy any need.  C# doesn't ask me to clean up her messes!  She cleans up after herself and she tries to make my life easier for me by taking on most of those optimization tasks C++ asked me to take upon myself.  Now, there are many of you who would say that I am the cause of my own grief, that it was my fault C++ didn't behave because I didn't pay enough attention to her.  That I alone caused the pain she inflicted on me.  And to some extent, you have a point.  But she was so high maintenance, requiring me to know every twist and turn of her vast and unrestrained power that any wrong term or bout of forgetfulness was met with painful reminders that she wasn't going to watch my back when I made a mistake.  But C#, she loves me when I'm good, and she loves me when I'm bad, and together we make beautiful code that is both fast and safe. So that's why I'm leaving C++ behind.  She says she's changing for me, but I have no interest in what C++0x may bring.  Oh, I'll still keep in touch, and maybe I'll see her now and again when she brings her problems to my door and asks for some attention -- for I always have a soft spot for her, you see.  But she's out of my house now.  I have three kids and a dog and a cat, and all require me to clean up after them, why should I have to clean up after my programming language as well?

• Bin packing part 6: Further improvements

  - by Hugo Kornelis

  In part 5 of my series on the bin packing problem, I presented a method that sits somewhere in between the true row-by-row iterative characteristics of the first three parts and the truly set-based approach of the fourth part. I did use iteration, but each pass through the loop would use a set-based statement to process a lot of rows at once. Since that statement is fairly complex, I am sure that a single execution of it is far from cheap – but the algorithm used is efficient enough that the entire...(read more)

• How should I pitch moving to an agile/iterative development cycle with mandated 3-week deployments?

  - by Wayne M

  I'm part of a small team of four, and I'm the unofficial team lead (I'm lead in all but title, basically). We've largely been a "cowboy" environment, with no architecture or structure and everyone doing their own thing. Previously, our production deployments would be every few months without being on a set schedule, as things were added/removed to the task list of each developer. Recently, our CIO (semi-technical but not really a programmer) decided we will do deployments every three weeks; because of this I instantly thought that adopting an iterative development process (not necessarily full-blown Agile/XP, which would be a huge thing to convince everyone else to do) would go a long way towards helping manage expectations properly so there isn't this far-fetched idea that any new feature will be done in three weeks. IMO the biggest hurdle is that we don't have ANY kind of development approach in place right now (among other things like no CI or automated tests whatsoever). We don't even use Waterfall, we use "Tell Developer X to do a task, expect him to do everything and get it done". Are there any pointers that would help me start to ease us towards an iterative approach and A) Get the other developers on board with it and B) Get management to understand how iterative works? So far my idea involves trying to set up a CI server and get our build process automated (it takes about 10-20 minutes right now to simply build the application to put it on our development server), since pushing tests and/or TDD will be met with a LOT of resistance at this point, and constantly force us to break larger projects into smaller chunks that could be done iteratively in a three-week cycle; my only concern is that, unless I'm misunderstanding, an agile/iterative process may or may not release the software (depending on the project scope you might have "working" software after three weeks, but there isn't enough of it that works to let users make use of it), while I think the expectation here from management is that there will always be something "ready to go" in three weeks, and that disconnect could cause problems. On that note, is there any literature or references that explains the agile/iterative approach from a business standpoint? Everything I've seen only focuses on the developers, how to do it, but nothing seems to describe it from the perspective of actually getting the buy-in from the businesspeople.

• Does Huawei E398 LTE Modem works with Netgear Router?

  - by Paul Smith

  I've been using a Netgear router sharing the signal through my Huawei E160 dongle, but following the speeds update and the device limit, it does not satisfy the demand. Through research, I've found that Huawei E398 is the latest and functional dongle so far. I'm going to update, but the confusion comes: Is it compatible for my Netgear router? Will it work? Any information will be appreciated. I found the unlocked E398 here.

• Backup File Naming Convention

    I have been asked this many times before and again just recently so I figured why not blog about it. None of this information outlined here is rocket science or even new but it is an area that I don’t think people put enough thought into before implementing.  Sure everyone choses some format but it often doesn’t go far enough in my opinion to get the most bang for the buck. This is the format I prefer to use: ServerName_InstanceName_BackupType_DBName_DateTimeStamp.xxx ServerName_InstanceName...(read more)

• Why Facebook profiles are Google-searchable?

  - by Jose

  Facebook has around 1B user profiles. They can be found by searching in Google. However, I don't think these profiles are linked from anywhere, so how could Google discover them? As far as I know, sitemaps are not enough for that (http://webmasters.stackexchange.com/a/5151), as all URLs should be crawlable anyway. I ask the question as I also have a site with user profiles and would like to make them discoverable.

• Career Advice: finding challenging work in software and web development

  - by dianovich

  Having left my physics degree early, I started out in the realm of web design / front end web development and was able to get work quite quickly. I moved on to spend a chunk of my time on servers and gained experience with frameworks like Wordpress and Drupal, then the likes of Codeigniter and CakePHP and became comfortable in Debian-based and RHEL/CentOS environments. I ventured in to iOS development and published a couple of native apps to the app store too! I have started to spend a good deal of my time writing Python and have invested a little time in Django. The problem is, I still spend a fair chunk of my time doing more front end web development (writing markup and CSS for site themes, design-lead JavaScript, small applications for which application architecture and software engineering are relatively unimportant or too time consuming to invest in) in my job. What I want to do is really exercise the systematic/logical portion of my brain and tackle challenging problems on a daily basis. I want to have to care about big-oh running times, modularity in software, DRY, performance tuning and development methodologies. I want to work for a firm whose clients say: "Yes, these things are important to us and we'll pay you to get them right." But it is difficult: I have no formal training and am potentially becoming a jack of all trades. Not that being a jack of many trades is necessarily a bad thing, but the scope of work I find myself involved in is far too broad. And, there are only so many hours in a day outside of work! My question is: where do I go from here? I am starting to work on a few open source projects and have started to publish content to my blog. But this isn't likely to make it past the recruitment consultants and HR departments of many-a-firm. And I do not, for example, work in a team that practices agile methodologies, so how do I get work in such a team to gain experience? While I have been responsible for implementing version control and some solid working practices into our current environment, there is only so far I can go in this context. What would convince you that i'm worth taking a risk? What would convince you that i'll have caught up the other guys in your employ in next to no time?

• Brightness Crash and Fan issues in 12.04.1

  - by S.A. McIntosh

  I would just like to state beforehand that I am a total novice in using Ubuntu when it comes to the more complex issues. So I thought it would be best to finally come here and ask for help before being re-directed or closed out for a solution. I have already looked high and low on this board for one but nothing came up for my particular case, so I might as well take a shot asking for the first time here. This is what I have at the moment: -Dell Insprion 1764 w/ 64-bit Intel i5 Core -Dual Boot: Windows 7/Ubuntu 12.04.1 32-bit (from 12.04 install) -Unity shell -Linux kernel: 3.2.0-32 generic-pae ...and this is my fglrxinfo: OpenGL vendor string: Advanced Micro Devices, Inc. OpenGL renderer string: ATI Mobility Radeon HD 5000 Series OpenGL version string: 4.2.11627 Compatibility Profile Context The one issue I have with using Ubuntu is brightness. With the driver in every time I use the slider in the brightness and lock settings or use the keyboard function, it freezes, goes black and comes up with a scrambled colors page like this in the video. So I have looked all over this board and the web for answers looking for a solution that might have an answer. This is what I have done so far to fix this: -First Solution: Looking around, I found this small fix using terminal: sudo gedit /etc/rc.local followed by adding this into "rc.local" echo # > /sys/class/backlight/acpi_video0/brightness This works rarely with the graphics driver still in and I often get lucky say during restart but reboot would only snap back the brightness at max. -Second Solution Simply remove the graphics driver while leaving the solution of first behind. This solves the issue but results in having the monitor flicker and flash at startup which in itself is not a problem to me but maybe not so good for monitor health. Also it causes the fan to speed up throughout the session and render any program that needs the driver useless. -Third Solution This is the most obvious. Just simply use the brightness on AMD Catalyst Control Center software that came with the driver, and I can say that it's form of brightness is HORRIBLE compared to the actual settings. Which leads up to where I am now, back to the driver to stop the fan speed-up and seems that the only solution to the brightness crash is to use the keyboard-controlled brightness at the login screen NOT the desktop if I want the issued effect but will just snap at max bright again if I restart. Fan speed problem is dealt with but now run the risk of crashing my computer if I so much touch the brightness settings. Speaking of which I found this on launchpad and it seems that the issue has been going far since June of 2012. Any help, redirect link or reference would be greatly appreciated. Thank you.

• "Well, Swing took a bit of a beating this week..."

  - by Geertjan

  One unique aspect of the NetBeans community presence at JavaOne 2012 was its usage of large panels to highlight and discuss various aspects (e.g., Java EE, JavaFX, etc) of NetBeans IDE usage and tools. For example, here's a pic of one of the panels, taken by Markus Eisele: Above you see me, Sean Comerford from ESPN.com, Gerrick Bivins from Halliburton, Angelo D'Agnano and Ioannis Kostaras from the NATO Programming Center, and Çagatay Çivici from PrimeFaces. (And Tinu Awopetu was also on the panel but not in the picture!) On one of those panels a remark was made which has kind of stuck with me. Henry Arousell, a member of the "NetBeans Platform Discussion Panel", who works on accounting software in Sweden, together with Thomas Boqvist, who was also at JavaOne, said, a bit despondently, I thought, the following words at the start of the demo of his very professional looking accounting software: "Well, Swing took a bit of a beating this week..." That remark comes in the light of several JavaFX sessions held at JavaOne, together with many sessions from the web and mobile worlds making the argument that the browser, tablet, and mobile platforms are the future of all applications everywhere. However, then I had another look at the list of Duke's Choice Award winners: http://www.oracle.com/us/corporate/press/1854931 OK, there are 10 winners of the Duke's Choice Award this year. Three of them (JDuchess, London Java Community, Student Nokia Developer Group) are not awards for software, but for people or groups. So, that leaves seven awards. Three of them (Hadoop, Jelastic, and Parleys) are, in one way or another, some kind of web-oriented solution, though both Hadoop and Jelastic are broader than that, but are service-oriented solutions, relating to cloud technologies. That leaves four others: NATO air defense software, Liquid Robotics software, AgroSense software, and UNHCR Refugee Registration software. All these are, on the software level, Java desktop solutions that, on the UI layer, make use of Java Swing, together with LuciadMaps (NATO), GeoToolkit (AgroSense), and WorldWind (Liquid Robotics). (And, it went even further than that, i.e., this is not passive usage of Swing but active and motivated: Timon Veenstra, during his AgroSense demo, said "There are far more Swing applications out there than we seem to think. Web developers just make more noise." And, during his Liquid Robotics demo, James Gosling said: "Not everything can be done in HTML.") Seems to me that Java Swing was the enabler of more Duke's Choice Award winners this year than any other UI-oriented Java technology. Now, I'm not going to interpret that one way or another, since I've noticed that interpretations of facts tend to validate some underlying agenda. Take any fact anywhere and you can interpret it to prove whatever opinion you're already holding to be true. Therefore, no interpretation from me. Simply stating the fact that Swing, far from taking a beating during JavaOne 2012, was a more significant user interface enabler of Duke's Choice Award winners than any other Java user interface technology. That's not an interpretation, but a fact.
