• The death of Kodak digital

  - by Ken Hortsch

  Months ago Kodak announced that it was discontinuing its digital video to focus on “significant opportunities for profitable growth”.  Three years ago I picked up the little Kodak Zi6 (pronounced Zix) for the kids for Christmas.  It is an HD pocket video camera with a nice 3” LCD all built into a something a bit longer than an deck of cards.  It is low tech and great!  The kids have had a ball with it, and for around $100 it was perfect.  It comes with 2 AA rechargeable batteries and the recharger.  You can add an SD card, but don’t need to, and the USB is not a cable but a pop-out dongle so everything is right in the one package.  Too many companies look for the next big thing and fail to see the stuff that is good enough, and right in front of their eyes.

• Making a Background Scrolling in Stacking Game

  - by David Dimalanta

  Hmmm...Is it a good idea to use a LibGDX parallax background for making a stacking game (i.e. PAPA STACKer Lite)? For example, I'm starting to use the blocks to drag-n-drop it. Next, when the next piece reaches the top of the screen, it automatically scrolls to the next one where the available space left. Aside from that, is it also involved with the camera code (Orthographic Camera) that the screen size appeared like 720x1280 but actually it's 1440x2560 for example? And another thing, does the background scrolling have the option to scroll from start to finish and infinite?

• Interacting with scene from controller/app delegate cocos2d

  - by cjroebuck

  I'm attempting to make my first cocos2d (for iphone) multiplayer game and having difficulty understanding how to interact with a scene once it is running. The game is a simple turn-based one and so I have a GameController class which co-ordinates the rounds. I also have a GameScene class which is the actual scene that is displayed during a round of the game. The basic interaction I need is for the GameController to be able to pass messages to the GameScene class.. such as StartRound/StopRound etc. The thing that complicates this is that I am loading the GameScene with a LoadingScene class which simply initialises the scene and replaces the current scene with this one, so there is no reference from GameController to GameScene, so passing messages is quite tricky. Does anyone have any ways to get around this, ideally I would still like to use a Loading class as it smooths out the memory hit when replacing scenes.

• front usb wont mount harddrives, internal usb ports do

  - by Thesgsuser

  I have noticed something in my new build, i am using Ubuntu desktop newest version my motherboard is the asus f1a75-m pro R2.0 with the usb ports in the back all my NTFS hard disks or usb sticks work fine, but then.. when i put them in the front usb ports of my chassis (silverstone milo ml-03) they wont mount... I have 2 usb 3.0 ports in front of the case connected with a internal usb 3.0 header. But i verified that the usb 3.0 ports on the back do mount the harddisk so it has nothing to do with usb 3.0 i think. The strange thing is, my mouse works fine on the front usb ports. Every usb hardware piece seems to work except if it has any memory inside it :( What seems to be the problem?

• host and share files in my hosting

  - by user1314836

  I currently have a domain+hosting with unlimited hosting space for our website. On the other hand, I use Dropbox to share our organizational files and photos between about 10 users. The thing is that sharing photos uses too much space for what a free Dropbox account offers. So I am thinking of taking advantage of my hosting space, but using FTP seems not to be ideal for users who are not too skilled with computers. In addition, it doesn't handle versions in case some user makes a mess of it. And using a public FTP to upload and giving them only download permission doesn't seem a good idea as I am only the CTO. So what I want is basically to implement a local Dropbox for a few users, but I'd prefer something that is not too complex to install/mantain. Thank you a lot.

• Blender: How to "meshify" an object I made from Bezier curves

  - by capcom

  I made a star shape using Bezier curves, and extruded it (see pic below): What I want to do is give it a rounder look - not just around the edges by using beveling. I want it to kind of look like this (well, that shape anyway): How would I go about doing this? Please keep in mind that I am extremely new to Blender. I thought that I could somehow turn this star into those default shapes that have tonnes of squares which I could pull out, and apply a mirror to it so that the same thing happens on both sides. I really don't know how to do it, and would appreciate your help.

• [Silverlight] How to choose the webcam resolution

  - by Benjamin Roux

  Hello, Today I’m gonna show you how to choose the webcam resolution when using Silverlight. By default most of them are in 640x480 which can be sometimes insufficient. VideoCaptureDevice source = devices.SelectedItem as VideoCaptureDevice; source.DesiredFormat = new VideoFormat(PixelFormatType.Unknown, 4096, 4096, 30); The magic thing with this line, is that the camera will choose the best resolution available (and not absolutely 4096x4096). You can also get all the supported formats using the SupportedFormats property. Hope this help.

• Deleted windows partition, now I can't get into Ubuntu

  - by Alejandro

  Back story: I installed ubuntu with wubi. I had windows on one NTFS partition, then I made a new NTFS partition in which I put wubi in and where My ubuntu OS was born. Eventually I moved /home into another partition and made a swap partition, but I digress. I deleted My original NTFS partition where windows is not thinking it would not matter but now I can't get into ubuntu. And the weird thing is that when I boot my computer I still see the option to boot into both windows and ubuntu. When I try to boot into windows, It tries to fix stuff and never succeds. When I try to boot into ubuntu, it shows me "cannot find GRLDR in all devices. Press CTRL+ALT+DELETE to restart". so, what do you guys think? I just want ubuntu running again, with all my stuff in /home there and all my system preferences how I like them.

• Should I always be checking every neighbor when building voxel meshes?

  - by Raven Dreamer

  I've been playing around with Unity3d, seeing if I can make a voxel-based engine out of it (a la Castle Story, or Minecraft). I've dynamically built a mesh from a volume of cubes, and now I'm looking into reducing the number of vertices built into each mesh, as right now, I'm "rendering" vertices and triangles for cubes that are fully hidden within the larger voxel volume. The simple solution is to check each of the 6 directions for each cube, and only add the face to the mesh if the neighboring voxel in that direction is "empty". Parsing a voxel volume is BigO(N^3), and checking the 6 neighbors keeps it BigO(7*N^3)-BigO(N^3). The one thing this results in is a lot of redundant calls, as the same voxel will be polled up to 7 times, just to build the mesh. My question, then, is: Is there a way to parse a cubic volume (and find which faces have neighbors) with fewer redundant calls? And perhaps more importantly, does it matter (as BigO complexity is the same in both cases)?

• Is there a decent way to maintain development of wordpress sites using the same base?

  - by Joakim Johansson

  We've been churning out wordpress sites for a while, and we'd like to keep a base repository that can be used when starting a new project, as well as updating existing sites with changes to the wordpress base. Am I wrong in assuming this would be a good thing? We take care of updating the sites, so having a common base would make this easier. I've been looking at solutions using git, such as forking a base repository and using it to pull changes to the wordpress base, but committing the site to it's own repository. Or maybe, if it's possible, storing the base as a git submodule, but this would require storing themes and plugins outside of that. Is there any common way to go about this kind of website development?

• Is there a way to procedurally generate the history of a world?

  - by pdusen

  I am somewhat intrigued by the diagram found here representing 1800 years of cultural history in an imaginary world some guy created. This sort of thing would seem to have strong applications for game development, insofar as world design. It looks like he did this diagram by hand. What I'm interested in is seeing if there is a way to create this sort of diagram programatically. If you were tasked with generating diagrams in the style of the above from random values, how would you go about it? Are there any particular data structures or algorithms that you would consider?

• What is 'work' in the Pomodoro Technique?

  - by Sachin Kainth

  I have just started to use Pomodoro today and I am trying to work out what I should and should not do during my 25 minute work time. For my 25 minute work stint I started to write some code and realised that I had done something similar in a related project so I opened that solution to copy and paste that existing code. Question is, is this allowed? Also, if during my 25 minutes I realise that there is an important work-related email that I need to send can I do that or should that wait for the next 25 minutes or the break. I am writing this question during my, now extended, 5 minute break. Is this work or is it a break? I really would appreciate some guidance as I really want to use Pomodoro to focus better on my work. Another thing that happened to me was that a Adobe AIR update alert came up on my desktop during the 25 minutes. Should I ignore such things until the break? Sachin

• CSS vendor prefixes redux

  Well, reactions to my proposal toabolish vendor prefixes are mixed, and I might have overshot my target here.Eric Meyer,Jonathan Snook, andStephen Hay reacted to my post,and it’s clear that they believe vendor prefixes ought to continue to exist. Manycommenters said the same thing, although some other commenters agreed with me.Daniel Glazman, W3C CSS co-chair, reactedin a similar vein, and agreed that there is something wrong with the current vendor prefiximplementation. He even welcomed the discussion....Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

• Visiting China

  - by Bill Graziano

  This summer I had the chance to visit China.  My brother and his wife are living in China and teaching English.  I spent a little over two weeks in Shanghai, Suzhou and Yancheng.  During that time I wrote some detailed updates for family and a few close friends on the impressions of a good Midwestern kid visiting the Middle Kingdom. I dumped them all into one document, did a little editing and now they’re posted.  You can download it here.  Below you can see my futile attempts to eat using chopsticks and me posing as a tourist on Nanjing Road in Shanghai.  The only thing I can say about chopsticks is that I didn’t starve.

• USB file transfer preparing to copy, but file count climbs indefinitely

  - by Alex

  I have downloaded Ubuntu 12.04 to back up my Windows machine that won't boot and am running Ubuntu from the CD. I copied and pasted a volume of about 160GB to my external HDD. The transfer has been stuck in the "preparing to copy" stage for several hours and is displaying a file/GB count about twice as high as the volume of data actually being copied! The number is now larger than the entire partition that's being copied from! However I know it's doing something because occasionally it pops up with a minor I/O error on this or that file which I then have to click through. I've not had this problem before so I can only assume it's a Linux/Ubuntu thing. More importantly what I want to know is is there any other way to copy it across that will actually work?

• What are the safety benefits of a type system?

  - by vandros526

  In Javascript: The Good Parts by Douglas Crockford, he mentions in his inheritance chapter, "The other benefit of classical inheritance is that it includes the specification of a system of types. This mostly frees the programmer from having to write explicit casting operations, which is a very good thing because when casting, the safety benefits of a type system are lost." So first of all, what actually is safety? protection against data corruption, or hackers, or system malfunctions, etc? What are the safety benefits of a type system? What makes a type system different that allows it to provide these safety benefits?

• SQL Server 2008 R2: StreamInsight - User-defined aggregates

  - by Greg Low

  I'd briefly played around with user-defined aggregates in StreamInsight with CTP3 but when I started working with the new Count Windows, I found I had to have one working. I learned a few things along the way that I hope will help someone. The first thing you have to do is define a class: public class IntegerAverage : CepAggregate < int , int > { public override int GenerateOutput( IEnumerable < int > eventData) { if (eventData.Count() == 0) { return 0; } else { return eventData.Sum()...(read more)

• Why fork a library for your own application?

  - by Mr. Shickadance

  Why should a programmer ever fork a library for inclusion in a widely used application? I ask this question because I was reading an article about why Chromium isn't packaged for many Linux distros like Fedora. Apparently its largely due to the fact that Google has forked a number of libraries, modified them, and included them in Chromium. This has driven up the complexity of packaging releases. There are a number of reasons why this can be a bad thing, but how strong a case can you actually make for doing so in a large widely used application such as Chromium? The original article: http://ostatic.com/blog/making-projects-easier-to-package-why-chromium-isnt-in-fedora Isn't it usually worth the effort to make slight modifications to your own program in order to use a popular and well developed library?

• The Apple iPad &ndash; I&rsquo;m gonna get it!

  - by Sahil Malik

  Ad:: SharePoint 2007 Training in .NET 3.5 technologies (more information). Well, heck, here comes another non-techie blogpost. You know I’m a geek, so I love gadgets! I found it RATHER interesting to see all the negative news on the blogosphere about the iPad. The main bitch points are - No Multi tasking No Flash Just a bigger iPhone. So here’s the deal! My view is, the above 3 are EXACTLY what I had personally hoped for in the Apple iPad. Before the release, I had gone on the record saying - “If the Apple Tablet is able to run full fledged iTunes (so I can get rid of iTunes on my desktop, I don’t like iTunes on Windows), can browse the net, can read PDFs, and will be under $1000, I’ll buy it”. Well, so, the released iPad wasn’t exactly like my dream tablet. The biggest downer IMO was it’s inability to run full iTunes. But, really, in retrospect, I like the newly released iPad. And here is why. No Multi tasking and No Flash, means much better battery life. Frankly, I rarely multi task on my laptop/desktop .. yeah I know my OS does .. but ME – I don’t multi task, and I don’t think you do either!! As I type this blogpost, I have a few windows running behind the scenes, but they are simply waiting for me to get back to them. The only thing truly running and I am making use of, other than this blogost, is media player playing some music – which the iPad can do. Also, I am logged into IM/Email – which again, iPad can do via notifications. It does the limited multitasking I need, without chewing down on batteries. Smart thinking, precisely the reason I love the iPhone. I don’t want a bulky battery consuming machine. Lack of flash? Okay sure, I can’t see Hulu on my iPad. That’s some loss. I can see youtube. Also, per Adobe I can’t see some porn sites, which I don’t want to see on my iPad. But, Flash is heavy. Especially flash video. My dream is to see silverlight run on the iPhone and iPad. No flash = not such a big loss. Speaking of battery life – 10 hours is plenty. I haven’t been away from electricity for that long usually, so I’m okay with charging it up when it runs low. It’s really not such a big deal honestly. Finally, eBook functionality – wow! I went on the record saying, eBook readers are not for me, but seriously, the iPad is perfect for my eBook needs at least. And as far it being just a bigger iPhone? I’ve always wanted a bigger iPhone, precisely for the eBook reading experience. I love my iPhone, I love the apps on it. The only thing that sucks about the iPhone is battery life, but other than that, it is the best gadget I have ever bought! And something that runs on mobile chips, is that thin, and those newly written apps .. mail, calendar .. I am very very excited to get my iPad, which will be the 64gig 3G version. The biggest plus in an iPad ……… no contract on data. I am *hoping*, this means that I can buy a SIM card in Europe, and use the iPad here. That would be killer awesome! But hey, if I had to pick downers in the iPad, they would be - - I wish they had a 128G Version. Now that we have a good video viewing machine, I know I’d chew up space quickly.- Sync over WIFI, seriously Apple.  Both for iPhone and iPad.- 3 month wait!!- Existing iPhone users should get a discount on the iPad data plan.

• Ubuntu 12.10 "Turn screen off when inactive for: Never" still turns off

  - by Will

  After a fresh install of Ubuntu 12.10, my screen still goes off after about ten minutes. I've been to the Brightness and Lock control panel. The Turn screen off when inactive for: setting is set for Never. I've been through the dconf Editor searching for power, screen, and idle changing parameters. This doesn't seem to have any effect on the display timeout. Here's one more interesting thing, the screen doesn't go off, per se. It just goes black. Meaning, the back lighting is still on, and all the pixels are black. When it goes black, it does a very pleasant quick dim to black. Similarly, it quickly un-dim's after a key press, mouse movement, or mouse click. So, I'm feeling this is more of a software setting the timeout, not a power saving function.

• Finally found a replacement for my.live.com&hellip;

  - by eddraper

  As I had alluded to before, the transition of http://my.live.com/ to http://my.msn.com/ caused me serious grief. I've been an RSS addict for many, many years and I found the my.live.com UI to be the ultimate RSS reader and gateway to the web. It had been my home page for a long time.  My.msn has a LONG way to go before it matches the elegance and performance of my.live. The site I ended up going with is http://www.netvibes.com/ .   It’s the closest thing I could find that could do four column tiles with a reasonable amount of information density .  I’d still prefer a lot less “chrome” and better use of space, but it’s as close as I’m going to get… One feature I really do like about netvibes, is the pagination feature.  The built in feed reader is also quite nice… All-in-all, I’d recommend netvibes…

• Getting started with ClojureScript and Google Closure

  - by Andrea

  I would like to investigate whether ClojureScript, with the associated Google Closure library is a reasonable tool to build modern, in-browser, Javascript applications. My current Javascript stack consists of jQuery, Backbone and RequireJS with the possible additions of some widgets libraries like jQueryUI or KendoUI. So it will be quite a big leap (I already know how to work in Clojure, although I have little experience). What is a good roadmap to do so? Should I learn the Google Closure library first, or can I grasp it together with ClojureScript? One thing I am concerned about is the overall application structure. Backbone is rather opinionated on how to organize your application. I am not sure whether Google Closure also includes some components to help with the design of the application. And, if this is the case, I do not know how to tell whether this structure will port to ClojureScript or a ClojureScript application will require a different organization anyway, and only use - say - the widgets and DOM manipulation features of Closure.

• Project of Projects with team Foundation Server 2010

  - by Martin Hinshelwood

  It is pretty much accepted that you should use Areas instead of having many small Team Projects when you are using Team Foundation Server 2010. I have implemented this scenario many times and this is the current iteration of layout and considerations. If like me you work with many customers you will find that you get into a grove for how to set these things up to make them as easily understandable for everyone, while giving the best functionality. The trick is in making it as intuitive as possible for both you and the developers that need to work with it. There are five main places where you need to have the Product or Project name in prominence of any other value. Area Iteration Source Code Work Item Queries Build Once you decide how you are doing this in each of these places you need to keep to it religiously. Evan if you have one source code file to keep, make sure it is in the right place. This makes your developers and others working with the format familiar with where everything should go, as well as building up mussel memory. This prevents the neat system degenerating into a nasty mess. Areas Areas are traditionally used to separate out parts of your product / project so that you can see how much effort has gone into each. Figure: The top level areas are for reporting and work item separation There are massive advantages of using this method. You can: move work from one project to another rename a project / product It is far more likely that a project or product gets renamed than a department. Tip: If you have many projects, over 100, you should consider categorising them here, but make sure that the actual project name always sits at the same level so you know which is which. Figure: Always keep things that are the same at the same level Note: You may use these categories only at the Area/Iteration level to make it easier to select on drop down lists. You may not want to use them everywhere. On the other hand, for consistency it would be better to. Iterations Iterations are usually used to some sort of time based consideration. Here I am splitting into Iterations with periodic releases. Figure: Each product needs to be able to have its own cadence The ability to have each project run at its own pace and to enable them to have their own release schedule is often of paramount importance and you don’t want to fix your 100+ projects to all be released on the same date. Source Code Having a good structure for your source even if you are not branching or having multiple products under the same structure is always a good idea. Figure: Separate out your products source You need to think about both your branches as well as the structure of your source. All your code should be under “Source” and everything you need to build your solution including Build Scripts and 3rd party tools should be under your “Main” (branch) folder. This should them be branched by “Quality”, “Release” or both to get the most out of your branching structure. The important thing is to make sure you branch (or be able to branch) everything you need to build, test and deploy your application to an environment. That environment may be development, test or even production, but I can’t stress the importance of having everything your need. Note: You usually will not be able to install custom software on your build server. Store any *.dll’s or *.exe’s that you need under the “Tools\Tool1” folder. Note: Consult the Branching Guidance for Team Foundation Server 2010 for more on branching Figure: Adding category may be a necessary evil Even if you have to have a couple of categories called “Default”, it is better than not knowing the difference between a folder, Product and Branch. Work Item Queries Queries are used to load lists of Work Items out of TFS so you can see what work you have. This means that you want to also separate queries out by Product / project to make it easier to Figure: Again you have the same first level structure Having Folders also in Work Item Tracking we do the same thing. We put all the queries under a folder named for the Product / Project and change each query to have “AreaPath=[TeamProject]\[ProductX]” in the query instead of the standard “Project=@Project”. Tip: Don’t have a folder with new queries for each iteration. Instead have a single “Current” folder that has queries that point to the current iteration. Just change the queries as you move from one iteration to another. Tip: You can ctrl+drag the “Product1” folder to create your “Product2” folder. Builds You may have many builds both for individual products but also for different quality's. This can be further complicated by having some builds that action “Gated Check-In” and others that are specifically for “Release”, “Test” or another purpose. Figure: There are no folders, yet, for the builds so you need a good naming convention Its a pity that there are no folders under builds, some way to categorise would be nice. In lue of that at the moment you can use a functional naming convention that at least allows you to find what you want. Conclusion It is really easy to both achieve and to stick to this format if you take the time to do it. Unless you have 1000+ builds or 100+ Products you are unlikely run into any issues. Even then there are things you can do to mitigate the issues and I have describes some of them above. Let me know if you can think of any other things to make this easier.

• I'm a CS student, and honestly I don't understand Knuth's books..

  - by Raymond Ho

  I stumbled this quote from Bill Gates: "You should definitely send me a resume if you can read the whole thing." He was talking about The Art of Programming books.. So I was pretty curious and want to read it all but honestly, I don't understand it at all.. I'm really not that highly intellectual being.. So this should be the reason why I can't understand it, but I am eager to learn.. I'm currently reading volume 1 about fundamental algo.. So is there any books out there that are friendly to novice/slow people like me? So I can build up myself and hopefully in the future I can read Knuth's book at ease..

• Google indexed my main site's content under subdomains

  - by Christie Angelwitch

  Google is indexing top level domain content as though it belongs on subdomains and I want to disable this. My site has wildcards enabled and we also have two subdomains with unique content. The first subdomain serves as a blog, the second one has only one page. Both have backlinks. Google has indexed content from the main site under the subdomains as well. Let's say that we have a page at example.com/page.html . The same page has also been indexed as subdomain.example.com/page.html as well and sometimes ranks better than the one located at the main site. The thing is that we never placed this content at the subdomain. I've thought about adding canonical tags at the subdomains to help with the duplicate content issue. How can I stop Google from indexing those pages? I don't even know how Google found those, since we never placed them at the subdomains.
