  • Opportunities in Cloud Computing

    - by Paul Sorensen
    A recent article from CIO Journal indicates that there is an extreme labor shortage (in certain technology areas) that is is leading to upward pressure on wages for IT Workers. This represents a great opportunity for those with certain skill-sets, among which include Java (Oracle certification is mentioned specifically). The article points out that a key driver of the labor shortage is the expansion of cloud computing. Cloud computing is set up to make life extremely simple for end-users, but the model pushes the complexity to back-end systems which are sophisticated, enterprise-level computing stacks (Oracle has an extensive set of cloud computing solutions). These complex systems require very highly-skilled IT professionals (the best-of-the-best) to successfully develop, implement, administer and maintain them. What this mean for you is that there is opportunity for those who have the appropriate skills at the appropriate levels. If you want to be a part of this opportunity you should do a self-assessment of your own skill-sets and experience. Based upon your results you can decide where it would be most appropriate to spend your time and resources for the highest return on your investment. By expanding and sharpening your skills and by gaining greater experience you will be better prepared to take advantage of career opportunities (like this) that come along periodically. As you evaluate your needs remember that Oracle University has a tremendous selection of high-quality eduction offerings (including training and certification) that can you help move your career forward. Thanks and best of luck!

  • OSB, Service Callouts and OQL

    - by Sabha
    Oracle Fusion Middleware customers use Oracle Service Bus (OSB) for virtualizing Service endpoints and implementing stateless service orchestrations. Behind the performance and speed of OSB, there are a couple of key design implementations that can affect application performance and behavior under heavy load. One of the heavily used feature in OSB is the Service Callout pipeline action for message enrichment and invoking multiple services as part of one single orchestration. Overuse of this feature, without understanding its internal implementation, can lead to serious problems. This series will delve into OSB internals, the problem associated with usage of Service Callout under high loads, diagnosing it via thread dump and heap dump analysis using tools like ThreadLogic and OQL (Object Query Language) and resolving it. The first section in the series will mainly cover the threading model used internally by OSB for implementing Route Vs. Service Callouts. The second section of the "OSB, Service Callouts and OQL" blog posting will delve into thread dump analysis of OSB server and detecting threading issues relating to Service Callout and using Heap Dump and OQL to identify the related Proxies and Business services involved. The final section of the series will focus on the corrective action to avoid Service Callout related OSB serer hangs. Before we dive into the solution, we need to briefly discus about Work Managers in WLS. Please refer to the blog posting for more details.

  • Writing generic code when your target is a C compiler

    - by enobayram
    I need to write some algorithms for a PIC micro controller. AFAIK, the official tools support either assembler or a subset of C. My goal is to write the algorithms in a generic and reusable way without losing any runtime or memory performance. And if possible, I would like to do this without increasing the development time much and compromising the readability and maintainability much either. What I mean by generic and reusable is that I don't want to commit to types, array sizes, number of bits in a bit field etc. All these specifications, IMHO, point to C++ templates, but there's no compiler for it for my target. C macro metaprogramming is another option, but, again my opinion, that greatly reduces readability and increases development time. I believe what I'm looking for is a decent C++ to C translator, but I'd like to hear anything else that satisfies the above requirements. Maybe a translator from another high-level language to C that produces very efficient code, maybe something else. Please note that I have nothing against C, I just wish templates were available in it.

  • Common way to store model transformations

    - by redreggae
    I ask myself what's the best way to store the transformations in a model class. What I came up with is to store the translation and scaling in a Vector3 and the rotation in a Matrix4. On each update (frame) I multiply the 3 matrices (first build a Translation and Scaling Matrix) to get the world matrix. In this way I have no accumulated error. world = translation * scaling * rotation Another way would be to store the rotation in a quaternion but then I would have a high cost to convert to a matrix every time step. If I lerp the model I convert the rotation matrix to quaternion and then back to matrix. For speed optimization I have a dirty flag for each transformation so that I only do a matrix multiplication if necessary. world = translation if (isScaled) { world *= scaling } if (isRotated) { world *= rotation } Is this a common way or is it more common to have only one Matrix4 for all transformations? And is it better to store the rotation only as quaternion? For info: Currently I'm building a CSS3D engine in Javascript but these questions are relevant for every 3D engine.

  • How do I turn off PCI devices?

    - by ethana2
    With the purchase of an Intel SSD and 85WHr Li-ion battery and the linking of wifi and bluetooth to my laptop's wireless switch, extensive Intel PowerTop usage, switching from compiz to metacity, stopping of the desktop-couch daemon, removal of Ubuntu One and several other services from my startup, disabling of everything possible in my BIOS, and physical removal of my optical drive, I've gotten my battery life up fairly high, but I think there's still more to be done. Specifically, when I'm in class taking notes, I want to temporarily but completely power down: Ethernet Firewire USB ports SD card reader Optical drive Webcam Sound card PCMCIA slot ..without turning them off in my BIOS like they are now, if possible, because then I have to restart my computer to use any of them. As it stands, I still haven't managed to power down: Firewire USB connection to webcam sound card How do I tell Linux to disable and power down these devices? Is it true that any PCI slot can be physically powered down? My current idle power consumption is 7.9 watts plus the screen. (10.0W at min. brightness) Also, how do I set the screen timeout to ten seconds? gconf editor isn't honoring it when I set it to that. Will switching from nVidia to Nouveau save any significant amount of power?

  • How do I implement deceleration for the player character?

    - by tesselode
    Using delta time with addition and subtraction is easy. player.speed += 100 * dt However, multiplication and division complicate things a bit. For example, let's say I want the player to double his speed every second. player.speed = player.speed * 2 * dt I can't do this because it'll slow down the player (unless delta time is really high). Division is the same way, except it'll speed things way up. How can I handle multiplication and division with delta time? Edit: it looks like my question has confused everyone. I really just wanted to be able to implement deceleration without this horrible mass of code: else if speed > 0 then speed = speed - 20 * dt if speed < 0 then speed = 0 end end if speed < 0 then speed = speed + 20 * dt if speed > 0 then speed = 0 end end end Because that's way bigger than it needs to be. So far a better solution seems to be: speed = speed - speed * whatever_number * dt

  • Advanced TSQL training

    - by Dave Ballantyne
    Over the past few years, Ive had it on my to do list to write and deliver and full-scale SQLServer training course and not just an hour long bite size session at user groups and conferences.  To me, SQLServer development is not just knowing and remembering the syntax of commands.  Sometimes I semi-jest that i have “Written a merge statement without looking up the syntax”, but I know from my interactions on and off line that I am far from alone in this.  In any case we have an awesome tool in the internet which is great at looking things up. When developing SQL Server based solutions,  of more importance is knowing the internals of the engine.  SQL Server is a complex piece of software and we need to be able to understand to a fairly low level ( you can always dive deeper ) the choices that it makes and why it makes them in order to deliver performant, reliable, predictable and scalable systems to our customers and end-users. This is the view i shall be taking over two days in March (19th and 20th) in London and ,TBH, one I dont see taken often enough. Early bird discounts are available until 31Dec. Full details of the course and a high level view of the bullet points we shall be covering are available at the Technitrain site ( http://tinyurl.com/TSQLTraining )

    - by Doctoa
    I have a modem device called Huawei ETS2051 and the Network Connection Manger can't detect it, but when I use Gnome-PPP it work fine but the problem is when I use Gnome-PPP; apps like Ubuntu software Center Can't reconice that's Iam connecting to the Internet so the app is just act like it's offline while other apps like web browsers and IM's work good under Gnome-PPP. any way what I want is to have a Full Ubuntu experince by making The Network Connection Manger detect my ETS2051. I have another 3G USB modem and The Network Connection Manger detect it and it's work just fine but the internet price for this one is high and I can't effort it so am count on that ETS2051 modem as you can see for it's low price and stable internet speed that satesfy my needs. More information: Gnome-PPP is a GUI for wvdial. the ETS2051 modem use a serial USB port. I have a Windows driver CD for the device. I have also find This qustion about the software Center acting like it's offline around wvdial and there's this launchpad bug. and am really insest to use Ubuntu Software Center so please no other software manger apps recomendation... I've also this Genius ColorPage HR6X Slim scanner that's Ubuntu can't detect it, so if you interset you can check and answer the qustion from here...

  • Should I not show all my skills?

    - by Cracker
    I have been programming for a very long time and I have in depth knowledge of several technologies. Recently I applied for a web development job and in my resume I had listed all the skills - HTML, CSS, JavaScript, jQuery, AJAX, PHP, ASP, JSP, C/C++, ARM. Except for C/C++ and ARM I had shown the skill level for all technologies as expert. Many of my friends had applied for the same job and they did not have any web development experience. ALL of them got a call for interview. However I got a rejection saying that we have received applications from very high level candidates and you have not be selected to go to the next level. This has seriously demotivated me. I do not understand why I have been rejected when I had all the required skills and all those who did not have any of the skills have been selected. One reason which I think is that the employer might be thinking that how one person can be an expert in all the technologies. Once in another interview I was told by the HR manager that it is unbelievable that you know ASP, JSP and PHP all in depth as we have different programmers for each of the technology. Such incidents make me very unhappy as in spite of being highly capable of the position I am rejected. Should I not list all my skills in the resume to avoid such situations?

  • XML Rules Engine and Validation Tutorial with NIEM

    - by drrwebber
    Our new XML Validation Framework tutorial video is now available. See how to easily integrate code-free adaptive XML validation services into your web services using the Java CAMV validation engine. CAMV allows you to build fault tolerant content checking with XPath that optionally use SQL data lookups. This can provide warnings as well as error conditions to tailor your validation layer to exactly meet your business application needs. Also available is developing test suites using Apache ANT scripting of validations.  This allows a community to share sets of conformance checking test and tools . On the technical XML side the video introduces XPath validation rules and illustrates and the concepts of XML content and structure validation. CAM validation templates allow contextual parameter driven dynamic validation services to be implemented compared to using a static and brittle XSD schema approach.The SQL table lookup and code list validation are discussed and examples presented.Features are highlighted along with a demonstration of the interactive generation of actual live XML data from a SQL data store and then validation processing complete with errors and warnings detection.The presentation provides a primer for developing web service XML validation and integration into a SOA approach along with examples and resources. Also alignment with the NIEM IEPD process for interoperable information exchanges is discussed along with NIEM rules services.The CAMV engine is a high performance scalable Java component for rapidly implementing code-free validation services and methods. CAMV is a next generation WYSIWYG approach that builds from older Schematron coding based interpretative runtime tools and provides a simpler declarative metaphor for rules definition.

  • Is it appropriate to run a complex enterprise-system configuration and migration project in a similar way to a Scrum development project?

    - by AndyM
    I'm just starting out on the implementation of a large enterprise-wide system, which has complex requirements and many stakeholders. The company has been through high-level evaluation and tender process and determined to purchase a highly configurable "off-the-shelf" product rather than building an entirely bespoke system. The system will replace several existing systems and will require a significant amount of data migration. I'm thinking that the implementation of this system (which is expected to take over 2 years) could be run in a similar way to a Scrum software development project. With the first sprints targeted at building the minimal possible functionality needed (across all functional areas), and then iteratively deepening the level of functionality according the stakeholder feedback. I think this will de-risk the project and help ensure a balance of stakeholder needs within the available time. The user stories are still the same, it's just that to implement them we have work within the constraints of the pre-purchased system. When it comes to 'building stuff', instead of writing custom code the team will be configuring the off-the-shelf package, writing data conversion scripts and the like (and it should be a lot quicker!). Does this sound like a sensible approach? Does the Agile approach makes sense here?

  • ECS with Go - circular imports [migrated]

    - by Andreas
    I'm exploring both Go and Entity-Component-Systems. I understand how ECS works, and I'm trying to replicate what seems to be the go-to document of ECS, namely http://cowboyprogramming.com/2007/01/05/evolve-your-heirachy/ For performance, the document recommends to use static arrays of every component type. That is, not arrays of component interfaces (arrays of pointers). The problem with this in Go is circular imports. I have one package, ecs, which contains the definitions for Entity, Component and System types/interfaces as well as an EntityManager. Another package, ecs/components, contains the various components. Obviously, the ecs/components package depends on ecs. But, to declare arrays of specific components in EntityManager, ecs would depend on ecs/components, therefore creating a circular import. Is there any way of avoiding this? I am aware that normally a high level system should not depend on lower systems. I'm also want to point out that using an array of pointers is probably fast enough for my purposes, but I'm interested in possible workarounds (for future reference) Thank you for your help!

  • Is using SVN for development and CM a bad practice?

    - by GatorGuy
    I have a bit of experience with SVN as a pure programmer/developer. Within my company, however, we use SVN as our configuration management tool. I thought using SVN for development at the same time was OK since we could use branches and the trunk for dev, and tags for releases. To me, the tags were the CM part, and the branches/trunk were the dev part. Recently a person, who develops high level code (but outside of the "pure SW" group) mentioned that the existing philosophy (mixing SVN for dev and CM) was wrong... in his opinion. His reasoning is that he thinks the company's CM tool should always link to run-able SW (so branches would break this rule). He also mentioned that a CM tool shouldn't be a backup utility for daily or incremental commits. Finally, he doesn't like the idea of having to jump from revision 143 to 89 in order to get a working copy... and further that CM tools shouldn't allow reversion to a broken state. In general he wants to separate the CM and back-up/dev utilties that SVN offers. Honestly, I am new and the person with this perspective is one of seniority, experience, and success, so I want to field this dilemma with the stackoverflow userbase to see if his approach has merit. My question: Should SVN be purely used for development, and another tool for CM (or vice versa)? Why? If so, what tools would you suggest for this combo? Or do you think that integrating both CM and dev into SVN is the best approach? Why? Thanks.

  • monitor height differences & the mouse going off screen

    - by fastmultiplication
    In ubuntu 10.10 I have a dual monitor setup. I have an nVidia graphics card and am using twinview. One of the monitors is 1024 pixels high and the other is 900. In the monitor configuration screen & in real life, I have them set up side by side, 1024 on the left. The result of this is that when I am on the bottom of the left monitor and move the mouse to the right, it goes into the hidden area below the right monitor's visible area. It seems like it would make a lot more sense for it to be bumped up to the bottom of the right monitor - since one almost never wants to move the mouse into an area of the screen that doesn't show up. And, systems I have used before have been set up that way. How can I set this up? I am not interested in lists of window managers for ubuntu; I would like to know the identity of a particular WM or set of steps I can take to solves the particular problem I have outlined above. Thanks! EDIT: I changed to use two seperate X window monitors, and set them up relatively positioned so that just the corner touches and the mouse can cross there, so the difference in heights doesn't matter.

  • Should a software developer get a yearly equipment budget?

    - by CrazyDart
    I am looking at a new position with a new company. I have talked to some people in the past (in general, not at this company) that they had been given a yearly budget to buy new computer stuff to keep up to date. Now why I feel this question is worth asking here is that Joel comes right out and says an employer should pay for the best equipment money can buy... within reason of course. From The Joel Test: 12 Steps to Better Code 9. Do you use the best tools money can buy? Writing code in a compiled language is one of the last things that still can't be done instantly on a garden variety home computer... Top notch development teams don't torture their programmers. Even minor frustrations caused by using underpowered tools add up, making programmers grumpy and unhappy. And a grumpy programmer is an unproductive programmer... Does anyone know if the industry has such a standard to offer an allowance or budget? I have never worked for a company like this, but I am thinking I should toss this in the ring for negotiations. Seems reasonable. How do bigger companies like MS, Google, and Apple handle this? If you say yes, give a range... I have been told numbers from $5k to $10k. Seems high to me, but hey I would gladly take it.

  • Rendering 8 bit graphics

    - by Matjaz Muhic
    I have a strong programming background just not from game development. I only made some pong and snake in high school and I did some OpenGL in college. I want to make my own game engine. Nothing fancy just a simple 2D game engine. But because I'm kinda old school and feeling retro. I want graphics to look like old 8 bit games (megaman, contra, super mario, ...). So how were the old games made back then? I want the simplest approach. Were they also using assets (images) like newer engines now do? How do you achieve this kind of rendering using OpenGL? Keep in mind. Simplest solution. I want to know how it was made back then and how I can replicate that. Doesn't even have to be OpenGL. I can draw on window canvas. I do want to make it from scratch basically.

  • How do I get a different type of scrollbars in 12.04? [closed]

    - by Joseph Garvin
    Possible Duplicate: How do I disable overlay scrollbars? By default 12.04 uses overlay scroll bars that do not suit my taste, and every method I've found so far of disabling them makes them broken in a different way. When I was using 11.10 this wasn't a problem because I could still change the GTK theme. In 12.04, the Appearance settings only contain a few stock themes, and other than the special purpose contrast ones they all have the overlay scroll bars. If I aptitude search gtk3 | grep theme I get no results so there appears to be no packaged alternative either. Most suggestions I've seen for disabling the overlay scroll bars involve uninstalling packages or editing files as root. I want to disable them just for the current user, not for everyone on the whole box; as should be the case for any theme/display setting. There is a gsettings command that temporarily disables the overlay scrollbars just for the current user, but this has two problems of its own: The setting doesn't stick after log off. Because who would want to save settings? The scroll bars put in place have no contrast. They have a black scroller on a black background and are completely unusable. In short what I'd like to know is how to disable overlay scroll bars such that: My preference is user specific. My preference is actually saved. The scroller can actually be seen against the background without having to use a special high contrast theme that makes my whole desktop look like a negative photo from Tron.

  • How to Program AWS Spot Instances to Strategically Bid So the Auction is Never Lost Until a Competitor Beats the Maximum I'm Willing to Pay?

    - by Taal
    I believe I'm in the right section of stack exchange to ask this. If not, let me know. I only use Amazon Web Services for temporary type hosting services, so the spot instances are quite valuable to me. I would also just make an instance and start and stop it - but - that doesn't necessarily fit my bootstrapped budget sadly. Anyways, it really kills me when someone outbids me on a spot instance I have (I tend to go for the larger ones which there are fewer of available) and I get randomly kicked off. I know or at least I believe there is a way to program in something somehow to dynamically change your bidding price to beat a potential competitor's if their's is higher than yours. Now, I previously believed Amazon would just charge me for the highest price right above the next lowest competitor automatically (eliminating the need for this) - so if I bid too high, then I only pay what I would of needed to in order to win and keep the auction. Essentially, I thought my bid price was my max bid price. Apparently, according to my bills and several experiments I've done - this is not the case. They charge me for whatever I bid even when I know there is no one else around to counter bid me. I needed to clarify that, but let me get back to the main point: Let's say I'm bidding $0.50, competitor comes in and bids 0.55 cents. I get kicked off. I want to have it to where I'd set a maximum I'm willing to pay (let's say $1.00 here), and then when competitor comes in and tries to bid $.55, my bid is dynamically adjusted to beat his at $0.56 up until he breaks my $1.00 threshold. I've been reading the guides and although they are more or less straightforward, I feel like they leave a few holes in them that end up confusing me. Like, for instance, where do I input said command or when do I do it? Maybe I'm just tech illiterate and need help deciphering these guides. A good start for someone willing to answer/help me decipher this problem would be here: http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/spot-as-update-bid.html

  • Hosting and domain registrations for multiple clients

    - by letseatfood
    I am finally getting regular work desiging, developing, and deploying websites for small businesses and individuals. So far the websites utilize single-user content management systems, so the websites create, as far as I know, minimal load on the shared servers. I have always required that each of my clients purchase annual shared hosting at Dreamhost. For domain registration, I ask that they register with Dreamhost, but some already have a registered domain elsewhere and this is fine with me. I do this so the billing issues are the client's responsibility, not mine. My question is: Since I can register unlimited domains and connect them to my one shared hosting account at Dreamhost, should I not be requiring clients to individually pay for shared hosting and a domain? Should I actually be paying for one hosting account and then hosting all of my client's websites on that account? As I said before, I currently have each client buy their own hosting, because I feel that, for example, if there is high traffic to their site, there would be less a chance of the site going down than if their site was hosted with many others on one account. I am famous for being long-winded, please let me know if I can clarify at all. Thanks!

  • I just received a complaint from a user of the website I maintain. Should I do anything?

    - by Chris
    I was sent sent a large wall of text from a user of the website I maintain at my job. They are clearly upset for having to deal with a horribly outdated web application that has not seen any serious updates in over 6+ years. No refactoring has been done, the code quality is terrible, the security unchecked, policy compliances ignored, in addition to being ugly and frankly embarrassing. Keep in mind this is a small business but the website is used by hundreds daily. I'm one of two programmers there, and I've been working there for two years. This person says they are about my age (22) and understand technology (but can't use proper grammar). The complaint mentioned awkward pages and actions on the website, but they don't even have a clue as to the depth of the flaws in this website. Now, I would love to honestly tell them that there's a lot wrong with this company and that this application was built when we were in high school. And that while it's not my fault that the website is terrible, I'm the one in position to fix it. But on the other hand, I could just say nothing and ignore it. Would doing this publicly have any advantage to future employees (showing integrity) or would it just be a completely pointless mistake? Odds are, even if I respond only that one person will ever read it. Regardless, I'm probably just going to ignore it and continue starting my project to refactor the website.

  • JEditorPane Code Completion

    - by Geertjan
    Code completion in a JEditorPane: Unfortunately, a lot of this solution depends on the Java Editor support in the IDE. Therefore, to use it, in its current state, you'll need lots of Java Editor related JARs even though your own application probably doesn't include a Java Editor. A key thing one needs to do is implement the NetBeans Code Completion API, using the related tutorial in the NetBeans Platform Learning Trail, but register the CompletionProvider as follows: @MimeRegistration(mimeType = "text/x-dialog-binding", service = CompletionProvider.class) Then in the TopComponent, include this code, which will bind all the completion providers in the above location, i.e., text/x-dialog-binding, to the JEditorPane: EditorKit kit = CloneableEditorSupport.getEditorKit("text/x-java"); jEditorPane1.setEditorKit(kit); FileObject fob; try {     fob = FileUtil.getConfigRoot().createData("tmp.java");     DataObject dob = DataObject.find(fob);     jEditorPane1.getDocument().putProperty(             Document.StreamDescriptionProperty,             dob);     DialogBinding.bindComponentToFile(fob, 0, 0, jEditorPane1);     jEditorPane1.setText("Egypt"); } catch (IOException ex) {     Exceptions.printStackTrace(ex); } Not a perfect solution, a bit hacky, with a high overheard, but a start nonetheless. Someone should look in the NetBeans sources to see how this actually works and then create a generic solution that is not tied to the Java Editor.

  • Anyone can suggest some Game Frameworks for GNU/Linux? [closed]

    - by dysoco
    So I've been developing a little bit with XNA + C# in Windows, not really much: just some 2D stuff, but I've found that XNA is a really good framework. I'm a GNU/Linux user, and I'm definitely migrating my desktop to Gentoo Linux (I've been using Arch in my laptop for a while now). But, of course, I need a C# + XNA alternative... I'm not really an expert in any language, so I can really pick up anything (except, maybe, Functional ones), I prefer C-Like languages like Java or Ruby, I tried Python but found the Whitespace syntax confusing. I would like to hear some of you'r suggestions, I'm not asking for "the best", but for "some suggestions", so I think this is objective enough. Probably you're going to suggest C++ + SDL, but I would prefer something more "High Level" like XNA, but I'm open to discuss anything. So... any ideas ? Note: I think this questions meets the guidelines for this site, if it doesn't: please not only downvote this question, but comment on what can I do to improve it. Thanks. PS: 2D Games, not 3D
