• Rain effect using DirectX 9 capabilities

  - by teodron

  Is it possible to achieve something similar to nVidia's rain demo using only shader model 3.0 capabilities? If yes, could you point out a few documents/web resources that are suitable candidates and do not require a heavy programming load (e.g. not more than two hard weeks of programming for one single person)? It would be nice if the answer could also contain a pro/con phrase for the proposed idea (e.g. postprocessing rain shader vs. a particle based effect).

• Concentrating on tedious manuals

  - by intuited

  Reading manuals is often boring — sometimes so boring that it becomes all but impossible to focus on the task. Yet.. so essential. As frustrating as it is to have to reread the same 2-page section four times in order to finally read the whole thing the whole way through without mentally skipping off to Marseilles in mid-paragraph, it's much worse to realize at some later point that you could have saved yourself hours of work by doing so. What sorts of jedi mind tricks — and not so jedi ones — can be employed to keep the mind focused on absorbing this critical matter?

Prior to joining Oracle, Rick held a variety of executive operational positions at Corning, Inc. and Bausch & Lomb. With a professional background that includes senior management positions in manufacturing, supply chain and information technology, Rick brings a unique set of experiences to cover the impact that technology can have on business models, processes and organizations. Rick will be hosting the IT Leader Editorial on a regular basis. I met my twin at Open World. We share backgrounds, experiences and even names. I hosted an invitation-only AppAdvantage Leadership Forum with an overcapacity 85 participants: 55 customers, 15 from the Oracle AppAdvantage team and 15 Partners. It was a lively, open and positive discussion of pace layered architectures and Oracle’s AppAdvantage approach to a unified view of Applications and Middleware. Rick Hassman from Pella was one of the customer panelists and during the pre event prep, Rick and I shared backgrounds and found that we had both been plant managers and led ERP deployments prior to leading IT itself. During the panel conversation I explored this with him, discussing the unique perspectives that this provides to CIO’s. He then hit on a point that I wasn’t able to fully appreciate until a week later. First though, some background. The week after the Forum, one of the participants emailed me with the following thoughts: “I am 150% behind this concept……but we are struggling with the concept of web services and the potential use of the Oracle Service Bus technology let alone moving into using the full SOA/BPM/BAM software to extend our JD Edwards application to both integrate and support business processes”. After thinking a bit I responded this way: While I certainly appreciate the degree of change and effort involved, perhaps I could offer the following: One of the underlying principles behind Oracle AppAdvantage is that more often than not, the choice between changing a business process and invasively customizing ERP represents a Hobson's Choice: neither is acceptable. In this case the third option, moving the process out of ERP, is the only acceptable one. Providing this choice typically requires end to end, real time interoperability across applications and/or services. This real time interoperability, to be sustainable over time requires a service oriented architecture. There's just no way around this. SOA adaptation is admittedly tough at the beginning. New skills, new technology and new headaches. But, like any radically new technology, it has a learning curve that drives cost down rather dramatically over time. Tough choices to be sure, but not entirely different than we face with every major technology cycle. Good points of course, but I felt that something was missing. The points were convincing, perhaps even a bit insightful, but they didn’t get at the heart of what Oracle AppAdvantage is focused upon: how the optimization of technology, applications, processes and relationships can change the very way that organizations operate. And then I thought back to the panel discussion with Rick Hassman at Oracle OpenWorld. Rick stressed that Continuous Improvement is a fundamental business strategy at Pella. I remember Continuous Improvement well as I suspect does everyone who was in American manufacturing during the 80’s. Pioneered by W. Edwards Deming in Japan (and still known alternatively as Kaizen), Continuous Improvement sets in place the business culture that we must not become complacent with success and resistant to the ongoing need for change. Many believe that this single handedly drove the renaissance in American manufacturing through the last two decades, which had become complacent during the 70’s and early 80’s. But what exactly does this have to do with SOA? It was Rick’s next point. He drew the connection that moving those business processes that need to continually change over time out of ERP and into edge applications and services enables continuous improvement by empowering people to continually strive for better ways of doing things rather than be being bound by workflows that cannot change. A compelling connection: that SOA, and the overall Oracle AppAdvantage framework of which it is an integral part, can empower people towards continuous improvement in business processes and as a result drive business leadership and business excellence. What better a case for technology innovation?

• 2d movement solution

  - by Phil

  Hi! I'm making a simple top-down tank game on the ipad where the user controls the movement of the tank with the left "joystick" and the rotation of the turret with the right one. I've spent several hours just trying to get it to work decently but now I turn to the pros :) I have two referencial objects, one for the movement and one for the rotation. The referencial objects always stay max two units away from the tank and I use them to tell the tank in what direction to move. I chose this approach to decouple movement and rotational behaviour from the raw input of the joysticks, I believe this will make it simpler to implement whatever behaviour I want for the tank. My problem is 1; the turret rotates the long way to the target. With this I mean that the target can be -5 degrees away in rotation and still it rotates 355 degrees instead of -5 degrees. I can't figure out why. The other problem is with the movement. It just doesn't feel right to have the tank turn while moving. I'd like to have a solution that would work as well for the AI as for the player. A blackbox function for the movement where the player only specifies in what direction it should move and it moves there under the constraints that are imposed on it. I am using the standard joystick class found in the Unity iPhone package. This is the code I'm using for the movement: public class TankFollow : MonoBehaviour { //Check angle difference and turn accordingly public GameObject followPoint; public float speed; public float turningSpeed; void Update() { transform.position = Vector3.Slerp(transform.position, followPoint.transform.position, speed * Time.deltaTime); //Calculate angle var forwardA = transform.forward; var forwardB = (followPoint.transform.position - transform.position); var angleA = Mathf.Atan2(forwardA.x, forwardA.z) * Mathf.Rad2Deg; var angleB = Mathf.Atan2(forwardB.x, forwardB.z) * Mathf.Rad2Deg; var angleDiff = Mathf.DeltaAngle(angleA, angleB); //print(angleDiff.ToString()); if (angleDiff > 5) { //Rotate to transform.Rotate(new Vector3(0, (-turningSpeed * Time.deltaTime),0)); //transform.rotation = new Quaternion(transform.rotation.x, transform.rotation.y + adjustment, transform.rotation.z, transform.rotation.w); } else if (angleDiff < 5) { transform.Rotate(new Vector3(0, (turningSpeed * Time.deltaTime),0)); //transform.rotation = new Quaternion(transform.rotation.x, transform.rotation.y + adjustment, transform.rotation.z, transform.rotation.w); } else { } transform.position = new Vector3(transform.position.x, 0, transform.position.z); } } And this is the code I'm using to rotate the turret: void LookAt() { var forwardA = -transform.right; var forwardB = (toLookAt.transform.position - transform.position); var angleA = Mathf.Atan2(forwardA.x, forwardA.z) * Mathf.Rad2Deg; var angleB = Mathf.Atan2(forwardB.x, forwardB.z) * Mathf.Rad2Deg; var angleDiff = Mathf.DeltaAngle(angleA, angleB); //print(angleDiff.ToString()); if (angleDiff - 180 > 1) { //Rotate to transform.Rotate(new Vector3(0, (turretSpeed * Time.deltaTime),0)); //transform.rotation = new Quaternion(transform.rotation.x, transform.rotation.y + adjustment, transform.rotation.z, transform.rotation.w); } else if (angleDiff - 180 < -1) { transform.Rotate(new Vector3(0, (-turretSpeed * Time.deltaTime),0)); //transform.rotation = new Quaternion(transform.rotation.x, transform.rotation.y + adjustment, transform.rotation.z, transform.rotation.w); print((angleDiff - 180).ToString()); } else { } } Since I want the turret reference point to turn in relation to the tank (when you rotate the body, the turret should follow and not stay locked on since it makes it impossible to control when you've got two thumbs to work with), I've made the TurretFollowPoint a child of the Turret object, which in turn is a child of the body. I'm thinking that I'm making it too difficult for myself with the reference points but I'm imagining that it's a good idea. Please be honest about this point. So I'll be grateful for any help I can get! I'm using Unity3d iPhone. Thanks!

• Can't adjust screen brightness on Macbook Pro 10,1 Ubuntu 13.10

  - by ben101

  I recently installed Ubuntu on my retina Macbook Pro (following this great guide: http://cberner.com/2013/03/01/installing-ubuntu-13-04-on-macbook-pro-retina/) Everything works fine so far however the screen brightness / backlight cannot be adjusted neither by using the assigned key nor by any other means. I know, I'm not the first to address this problem, but all the suggested solutions I found so far did not work for me. I unsuccessfully tried the following: Including Option "RegistryDwords" "EnableBrightnessControl=1" in the Devices-Section of /etc/X11/xorg.conf the application xbacklight I also haven't found any file such as mbp_backlight or apple_backlight on my system which probably would be a starting point I'm using the Nvidia-driver. (BTW: With the nouveau-driver, the keys to adjust the brightness work. However, with the nouveau driver Ubuntu does not resume from suspend mode) Any suggestions what I can do? Thanks!

• Using Amazon S3/Cloudfront and Encoding.com to deliver web video – step by step for iPhone/iPod/iPad

  - by joelvarty

    The Amazon AWS newsletter for May 2010 had a great link in it to this article by encoding.com on how you can use they service to encode your video for multi-format, multi-bandwidth streaming to many devices, including iPhone, iPad, and Flash with H264.   This looks like it doesn’t actually take advantage of CloudFront streaming, but merely splits your encoded files into the available chunks and includes all of the M3U8 files that point to the different bitrates and such.   This looks like a pretty sweet service in general, especially since they seem to have an API as well, so that may be very useful to those of you out there looking to host video. more later – joel

• Trying to keep up with Technology and Blogging

  - by Dave Campbell

  A little bit of everything... The heading above got changed a bunch during writing and I finally settled on that because this has become a 'stream of consciousness' post... or maybe a stream of UNconsciousness :) If you've noticed, my blogging has been a tad slow this fall. There's been a lot going on personally. But then again, I haven't skipped anybody either. Rather than go through ALL the blogs I have aggregated, and take a week to get to the bottom, at some point in the last year, I had moved the lists around so I now have "SilverlightMVPs", "Very Prolific", "WP7", and "Top Checks". This is a total of about 250 of the more prolific bloggers. Those 250 bloggers have kept me very busy up through about //BUILD. Sometimes it would take all week to go through just that list putting out 13 posts per blog per day... but not anymore. This weekend I made it all the way through the BIG list... close to 700 blogs, and if you read my blog, you know I had one medium day (Saturday), and yesterday was very short. Why is this? To be honest, I don't know... is everybody busy re-tooling, or churning waiting for direction? I have a short list of WinRT/Metro/W8 folks... maybe I need to be pointed to more of them... but my old favorites are not pumping out posts as they have in the past. I said before that I am attracted to Metro, and I've already got My first Metro app post out there, and were it not for working with the new site, I'd have had another out last weekend... so definitely look for more from me in that area. New Site? Did I say 'new site' ? oops... didn't mean to do that, but now that the cat is out of the bag, I may as well continue... While at //BUILD, I discussed a re-tooling of SilverlightCream with lots of folks... probably more than wanted to hear about it to be honest! ... it's needed a facelift, and there's stuff on there that never worked right, plus there's a lot of manual effort that goes into a blog post. In an effort to alleviate all the above, Michael Washington and I have been working on the next iteration of SilverlightCream. Not wanting to lose that branding or mess with any saved links, I decided to change from a somewhat funky name to something more professional. I also decided to put my blog on the site, and tie my main announcement twitter feed to the site as well. The way things sit today, there are 3 different names in those locations and it's gotta be confusing for folks just stumbling in. We're going to do a series of posts talking about the site and the new backend processing (hint: Michael Washington is responsible for it, so you can take a guess at the technology), but for now, we'd like some eyes on the front end of the site, and some submittals using it to see if it falls over somewhere that we haven't tried. So... I'm going to give it up... the new site is Windows Dev News. The Twitter feed is @WindowsDevNews, and the blog will be on the site as well at Windows Dev News Blog. I've got the RSS Feed on Feedburner too, so I think all the nuts and bolts are good to go. The submittal and search pages work, as does the blog page. You'll notice we used the MasterPage from SilverlightCream to get started. That will probably change, but it's just the visual... the content is the important part. Other missing things are the tracking and 'Skim' page that we will eventually have up and running. There are some formatting issues with the blog posts but if you hang in there with me, those will be taken care of. If you're a blogger, please submit through the site and let me know if you find any problems. If you're a reader, please add this feed and site. I'll be duplicating the effort for a while but at some point will stop that foolishness. We won't lose the data from SilverlightCream though, so keep using that as a search resource... I have hopes to pull that database over to WindowsDevNews, or link to it in some manner... that part isn't set in jello yet, but it will not be lost. So there it is... let me know what you think, send me your WinRT/Metro/W8 postings along with your Silverlight and WP7 posts... it's not that different, it's just more. Stay in the 'Light

• An MCM exam, Rob? Really?

  - by Rob Farley

  I took the SQL 2008 MCM Knowledge exam while in Seattle for the PASS Summit ten days ago. I wasn’t planning to do it, but I got persuaded to try. I was meaning to write this post to explain myself before the result came out, but it seems I didn’t get typing quickly enough. Those of you who know me will know I’m a big fan of certification, to a point. I’ve been involved with Microsoft Learning to help create exams. I’ve kept my certifications current since I first took an exam back in 1998, sitting many in beta, across quite a variety of topics. I’ve probably become quite good at them – I know I’ve definitely passed some that I really should’ve failed. I’ve also written that I don’t think exams are worth studying for. (That’s probably not entirely true, but it depends on your motivation. If you’re doing learning, I would encourage you to focus on what you need to know to do your job better. That will help you pass an exam – but the two skills are very different. I can coach someone on how to pass an exam, but that’s a different kind of teaching when compared to coaching someone about how to do a job. For example, the real world includes a lot of “it depends”, where you develop a feel for what the influencing factors might be. In an exam, its better to be able to know some of the “Don’t use this technology if XYZ is true” concepts better.) As for the Microsoft Certified Master certification… I’m not opposed to the idea of having the MCM (or in the future, MCSM) cert. But the barrier to entry feels quite high for me. When it was first introduced, the nearest testing centres to me were in Kuala Lumpur and Manila. Now there’s one in Perth, but that’s still a big effort. I know there are options in the US – such as one about an hour’s drive away from downtown Seattle, but it all just seems too hard. Plus, these exams are more expensive, and all up – I wasn’t sure I wanted to try them, particularly with the fact that I don’t like to study. I used to study for exams. It would drive my wife crazy. I’d have some exam scheduled for some time in the future (like the time I had two booked for two consecutive days at TechEd Australia 2005), and I’d make sure I was ready. Every waking moment would be spent pouring over exam material, and it wasn’t healthy. I got shaken out of that, though, when I ended up taking four exams in those two days in 2005 and passed them all. I also worked out that if I had a Second Shot available, then failing wasn’t a bad thing at all. Even without Second Shot, I’m much more okay about failing. But even just trying an MCM exam is a big effort. I wouldn’t want to fail one of them. Plus there’s the illusion to maintain. People have told me for a long time that I should just take the MCM exams – that I’d pass no problem. I’ve never been so sure. It was almost becoming a pride-point. Perhaps I should fail just to demonstrate that I can fail these things. Anyway – boB Taylor (@sqlboBT) persuaded me to try the SQL 2008 MCM Knowledge exam at the PASS Summit. They set up a testing centre in one of the room there, so it wasn’t out of my way at all. I had to squeeze it in between other commitments, and I certainly didn’t have time to even see what was on the syllabus, let alone study. In fact, I was so exhausted from the week that I fell asleep at least once (just for a moment though) during the actual exam. Perhaps the questions need more jokes, I’m not sure. I knew if I failed, then I might disappoint some people, but that I wouldn’t’ve spent a great deal of effort in trying to pass. On the other hand, if I did pass I’d then be under pressure to investigate the MCM Lab exam, which can be taken remotely (therefore, a much smaller amount of effort to make happen). In some ways, passing could end up just putting a bunch more pressure on me. Oh, and I did.

• Apress Books - 4 - Introducing Visual C# 2010 - Initial comments

  - by TATWORTH

  Apress books Visual C# 2010 (ISBN 978-1-4302-3171-4) - http://www.apress.com/book/view/1430231718 is both an excellent introduction to C# programming and a manual for those with experiance. So far I have only been through a few chapters but I have been favourably impressed. In the chapter on Exceptions, I have posted an errata regarding the custom exception in  listing 14-17; it is missing an overload required by FXCOP     private CustomException(SerializationInfo info, StreamingContext context) : base(info, context)     {     } Aside of this minor point, I have no hesitation to recommending this book to anyone who wishes to learn C#.

• The purpose of using a constants pool for immutable constants

  - by patstuart

  Originally posted at stackoverflow.com/q/23961260 I come across the following code with a lot of frequency: if (myArray.length == Constants.ZERO_INT) or if (myString != null && !myString.equals(Constants.EMPTY_STRING)) Neither of these makes much sense to me. Isn't the point of having a constant pool for ease of code appearance and to allow for modularity? In both of the above cases, it just looks like needless noise that accomplishes neither objective. My question: what is the purpose of using a constants pool for variables like this which will never change? Or is this just cargo cult programming? If so, then why does it seem to be prevalent in the industry? (I've noticed it with at least two different employers I've worked with).

• rsnapshot intervals in configuration file…

  - by Patrick

  A simple question about rsnapshot. In order to perform daily backups I'm going to add lines to cron in my Ubuntu. Then, why do I have also these lines in the rsnapshot.conf ? ######################################### # BACKUP INTERVALS # # Must be unique and in ascending order # # i.e. hourly, daily, weekly, etc. # ######################################### interval hourly 6 interval daily 7 interval weekly 4 #interval monthly 3 If I use cron, should I disable them ? thanks ps. I've just realized that in the crontab I still have "hourly" and "daily". Should I then uncomment only the one I use in the crontab ? And what's the point to specify hourly if it is already specified in cron ? I'm a bit confused. # crontab -e 0 */4 * * * /usr/local/bin/rsnapshot hourly 30 23 * * * /usr/local/bin/rsnapshot daily

• How to Convert a PFX Certificate into a JKS Certificate to configure it on WebLogic

  - by adejuanc

  To convert a pfx cert file to a jks file, please follow these instructions: 1. Set up the environment for the domain, by executing the setDomainEnv.sh script, typically located at $DOMAIN_HOME/bin. $ . ./setDomainEnv.sh 2. Use OpenSSL to check the pfx certificate's content. $ openssl pkcs12 -in <certificate.pfx> -out KEYSTORE.pem -nodesAt this point, a password for the pfx file will be requested. Expected output: $ openssl pkcs12 -in <certificate.pfx> -out KEYSTORE.pem -nodesEnter Import Password:MAC verified OK3. Open KEYSTORE.pem file, from step 2.

• Can we replace XML with JSON entirely?

  - by Saeed Neamati

  I'm sure lots of developers are familiar with XML and JSON, and they've used both of them. Thus no point in explaining what they are, and what is their purpose, even in brief. If we try to map their concepts, we can say (correct me if I'm wrong): XML tags are equivalent to JSON {} XML attributes are equivalent to JSON properties XML tag collection is equivalent to JSON [] The only thing I can think of, which doesn't exist in JSON, is XML Namespaces. The question is, considering this mapping, and considering that JSON is highly lighter in this mapping, can we see a world in future (or at least theoretically think of a world) without XML, but with JSON doing everything XML does? Can we use JSON everywhere XML is used? PS: Please note that I've seen this question. It's something entirely different from what I'm asking here. Thus please don't mention duplicate.

• What are some great resources about programming contemporary GUIs and GUI architecture patterns?

  - by snitko

  So I've read Martin Fowler's old blog post http://martinfowler.com/eaaDev/uiArchs.html which describes various approaches to building GUI from an architecture point of view, discussing patterns and how they were used. But this blog post was written in 2006. Since then, there must have been some new ideas in the field? I was curious whether anyone knows about a similar guide to GUI architectures, but describing contemporary systems? The reason I'm interested in something abstract and theoretical to read is because it really is difficult and time consuming to ACTUALLY learn how ALL of the contemporary frameworks work, given their diversity and the diversity of the languages they are written in. I am primarily a web developer, so I'm familiar with Rails and some Javascript frameworks. But I would also like to know how GUI is built on Android or in Cocoa or in Windows, but without having to learn all of those things.

• Web security course ?

  - by vtortola

  I'd like to do a course about web security. I've seen some certifications that could be interesting: CIW Web Security Professional CISSP® - Certified Information Systems Security Professional Certified Secure Software Lifecycle Professional What do you know about these certifications? are they recognized? I'm not trying to become a hacker, I just want to ensure I have enough knowledge about web security to cope with today internet. From my inexpert point of view, "Certified Secure Software Lifecycle Professional" looks exactly as I want, the problem is that it cost more than 500 bucks! Why certification? well, I want to learn but I would like also have a way to demonstrate to a future employer/customer that I had to study and pass exams, not only attend to a course. Regards.

• ASP.NET 4.0 meta tags and Search engine optimisation

  - by nikolaosk

  I am thinking to create a new series of posts regarding ASP.NET and SEO (Search Engine Optimisation). I am going to start with this post , talking about some new features that make our asp.net apps more SEO friendly. At the end of the day, there is no point having a great application and somehow "scare" the search engines away. This is going to be a short post so let's quickly have a look at meta keywords and ASP.NET 4.0. Meta keywords and description are important elements of a page and make it...(read more)

• TDD - A question about the approach

  - by k25

  I have a question about TDD. I have always seen the recommendation that we should first write unit tests and then start writing code. But I feel that going the other way is much more comfortable (for me) - write code and then the unit tests, because I feel we have much more clarity after we have written the actual code. If I write the code and then the tests, I may have to change my code a little bit to make it testable, even if I concentrate much on creating a testable design. On the other hand, if I write the tests and then the code, the tests will change pretty frequently as and when the code shapes up. My questions are: 1) As I see a lot of recommendations to start writing tests and then move on to coding, what are the disadvantages if I do it the other way - write code and then the unit tests? 2) Could you please point me to some links that discuss about this or recommend some books (TDD)?

  Derek Brink is Vice President and Research Fellow in IT Security for the Aberdeen Group.  He has established himself as an IT Security Expert having a long and impressive career with companies and organizations ranging from RSA, Sun, HP, the PKI Forum and the Central Intelligence Agency.  So shouldn't he be talking about "Best Practices in IT Security?" In his latest blog he talks about the thought processes that drive the wrong behavior, and very cleverly shows how that incorrect thinking exposes weaknesses in our IT environments. Check out his latest blog post titled: "The Screwtape CISO: Memo #1 (silos, stovepipes and point solutions)"

• Application Lifecycle Management with Visual Studio 2010 – Wrox Book

  - by Guy Harwood

  After running with a somewhat disconnected set of tools (vs 2008, Ontime, sharepoint 2007) for managing our projects we decided to make the move to Team Foundation Server 2010.  With limited coverage of the product available online i went in search of a book and found this… View this book on the Wrox website I must point out that i have only read 10 of the 26 chapters so far, mainly the ones that cover source code control, work item tracking and database projects.  This enables our dev team to get familiar with it before switching project management over at a future date. Needless to say i am very impressed with the detail it provides, answering pretty much every question i had about TFS so far.  I'm looking forward to digging into the sections on testing, code analysis and architecture. Highly recommended.

• How can you learn to design nice looking websites?

  - by Richard

  I am a moderately capable web developer. I can put stuff where I want it to go and put some JQuery stuff in there if I need to. However, if I am making my own website (which I am starting to do) I have no idea how to design it. If someone was to sit next to me a point to the screen and say "put this picture there, text there" I can do that quite easily. But designing my own site with my choice of colours and text will look like a toddler has invented it. Does anyone know any websites/books I can look at or has anyone got any tips on the basics of non-toddler web design?
