• Should I install ubuntu on USB instead of HDD dual-boot?

  - by user2147243

  I had Ubuntu 12.04 installed as dual-boot OS on top of Vista on my laptop. Hacked the grub settings to default to Vista (instead of the default Ubuntu -- pain) on startup, and all was OK for occasional Ubuntu use for past 6 months. Then last week I got a strange message about 'lack of disk space' (~50MB free) when installing pxyplot, even though there was still about 6GB free disk space when I checked later. Then today the Ubuntu wouldn't load at all, and checking the HDD partitions in Vista it looked like the 15GB Ubuntu partition was now three smaller partitions! So, I got rid of those partitions and expanded the Vista partition to use the reclaimed space. Now can't restart ('grub rescue' appears and doesn't 'rescue' anything), so I'll have to do a boot recovery using a Vista installation CD. (Not a particularly user-friendly failure mode of the dual-boot installation!) I now have to decide to either a) try installing ubuntu on the HDD again, but don't want to stuff up my Vista ever again, as that is my most used OS, or b) install Ubuntu on a 16GB USB 3.0 stick. Apparently performance from USB won't be as good as from HDD, and running OS from USB stick does lots of r/w so the stick may fail after a few years! Perhaps installing Ubuntu on live USB and setup to then run in RAM would alleviate the performance/USB lifespan problems? If I create a live-USB for Ubuntu OS, will it boot off that when I restart the laptop with it plugged in? Or will I have to change the laptop setting for boot-order whenever I want to boot Ubuntu instead of Vista (that would be even more painful than the grub default boot order putting Ubuntu ahead of the existing Vista OS!) -- update: I recovered my Vista setup using Iolo SystemMechanic Disaster Recovery Tool, and created a bootable USB of Ubuntu 13.10 on an 8GB USB3.0 pendrive, with 4GB of 'persistence' to allow saving of settings, install some packages etc. It worked OK for a couple of test boots, but once I changed the time and desktop wallpaper, the next Ubuntu reboot crashed and I then couldn't get it to boot successfully. So I decided to install Ubuntu 12.04 LTS as a dual-boot again, but this time instead of partitioning the HDD and installing from an ISO DVD I used the wubi.exe tool to install Ubuntu as a dual-boot. Worked very well, although one oddity was that, despite asking how big the make the partition (20GB), the installed Ubuntu appears to be happily installed somewhere within the Vista NTFS file system (no partition shows up in Windows disk manager, and in Ubuntu disk management tool the entire 133 GB of HDD is showing, with ~40GB free space). A nice feature of installing the dual-boot using wubi is that the laptop now uses Windows boot manager on startup, with Vista as the default OS and Ubuntu happily listed as second on the list. So far so good.

• Visual studio Real Dark mode (2010,2012,2013)

Soon we got some theme plugin  which make us able to modify the look of visual studio.   http://studiostyl.es/ already provide lots of wonderful color scheme that make you able to modify the theme. These themes are also work in webmatrix 2.  Webmatrix 2 have a plugin for themes that is made by Yishai Galatzer that is awesome for webmatrix 2.   In Visual studio 2012 we got a native dark mode. This means we can configure it without any plugin or requirement of anything. In this post I have a demo to show you how to use Dark mode that is part of Windows 7 (and windows 8 too).   Few months ago I show a problem that webmatrix 2 run slow. it’s run better in windows 7 dark mode. Windows 7 dark mode simply refer to right click > personalize > High contrast theme in bottom of windows. This setting make thing a little bit faster.   When you have set this you have seen that Visual studio doesn’t react good anymore because it’s color scheme is broken now. What you need now is import any theme from http://studiostyl.es/ When you import this this will look good as this.   This is the demo look of Windows 7 phone Express 2010. It will react same for future version as 2012, 2013. Now see your VS react look dark. Everything is dark now. Your Firefox and IE will not run totally in blackish mode but you can use chrome. Chrome have less effect of dark. Now if you benchmark it then you will feel that everything that take a long time in loading now run fast.   Note :- This is experiments. Remember to have settings backup before apply new theme. All thing I do is make my VS run faster. If you have any trouble or idea please comment it.   Thanks for read my post

• Client-Server connection response timeout issues

  - by Srikar

  User creates a folder in client and in the client-side code I hit an API to the server to make this persistent for that user. But in some cases, my server is so busy that the request timesout. The server has executed my request but timedout before sending a response back to client. The timeout set is 10 seconds in client. At this point the client thinks that server has not executed its request (of creating a folder) and ends up sending it again. Now I have 2 folders on the server but the user has created only 1 folder in the client. How to prevent this? One of the ways to solve this is to use a unique ID with each new request. So the ID acts as a distinguisher between old and new requests from client. But this leads to storing these IDs on my server and do a lookup for each API call which I want to avoid. Other way is to increase the timeout duration. But I dont want to change this from 10 seconds. Something tells me that there are better solutions. I have posted this question in stackoverflow but I think its better suited here. UPDATE: I will make my problem even more explicit. The client is a webbrowser and the server is running nginx+django+mysql (standard stack). The user creates a folder in webbrowser. As a result I need to hit a server API. The API call responds back, thereby client knows API call was success. This is normal scenario. Sometimes though, server successfully completes the API request but the client-side (webbrowser) connection timesout before server can respond back. The client has no clue at this point. The user thinks the request was a fail & clicks again. This time it was a success but when the UI refreshes he sees 2 folders. I want to remedy this situation.

As retail dies, whom will be the winners? | Peter Evans-Greenwood "The problem for many retailers is that how consumers shop has changed but the the retailers haven't adapted, " says Peter Evans-Greenwood. "Their sole virtue was to be the last step in a supply chain delivering somebody else's products to the consumer. However, being the last step in the supply chain is no longer a virtue when consumers skip across channels and can reach around the globe, no longer dependant on or limited to what they can find locally." Thought for the Day "Brains require stimulation. If you're locked into a pattern of work, work, and more work, your brain soon habituates - the same way that it lets you stop hearing a clock ticking.

• Software Tuned to Humanity

  - by Phil Factor

  I learned a great deal from a cynical old programmer who once told me that the ideal length of time for a compiler to do its work was the same time it took to roll a cigarette. For development work, this is oh so true. After intently looking at the editing window for an hour or so, it was a relief to look up, stretch, focus the eyes on something else, and roll the possibly-metaphorical cigarette. This was software tuned to humanity. Likewise, a user’s perception of the “ideal” time that an application will take to move from frame to frame, to retrieve information, or to process their input has remained remarkably static for about thirty years, at around 200 ms. Anything else appears, and always has, to be either fast or slow. This could explain why commercial applications, unlike games, simulations and communications, aren’t noticeably faster now than they were when I started programming in the Seventies. Sure, they do a great deal more, but the SLAs that I negotiated in the 1980s for application performance are very similar to what they are nowadays. To prove to myself that this wasn’t just some rose-tinted misperception on my part, I cranked up a Z80-based Jonos CP/M machine (1985) in the roof-space. Within 20 seconds from cold, it had loaded Wordstar and I was ready to write. OK, I got it wrong: some things were faster 30 years ago. Sure, I’d now have had all sorts of animations, wizzy graphics, and other comforting features, but it seems a pity that we have used all that extra CPU and memory to increase the scope of what we develop, and the graphical prettiness, but not to speed the processes needed to complete a business procedure. Never mind the weight, the response time’s great! To achieve 200 ms response times on a Z80, or similar, performance considerations influenced everything one did as a developer. If it meant writing an entire application in assembly code, applying every smart algorithm, and shortcut imaginable to get the application to perform to spec, then so be it. As a result, I’m a dyed-in-the-wool performance freak and find it difficult to change my habits. Conversely, many developers now seem to feel quite differently. While all will acknowledge that performance is important, it’s no longer the virtue is once was, and other factors such as user-experience now take precedence. Am I wrong? If not, then perhaps we need a new school of development technique to rival Agile, dedicated once again to producing applications that smoke the rear wheels rather than pootle elegantly to the shops; that forgo skeuomorphism, cute animation, or architectural elegance in favor of the smell of hot rubber. I struggle to name an application I use that is truly notable for its blistering performance, and would dearly love one to do my everyday work – just as long as it doesn’t go faster than my brain.

• C++ and SDL resource management for 2D game

  - by KuruptedMagi

  My first question is about stateManagers. I do not use the singleton pattern (read many random posts with various reasons not to use it), I have gameStateManager which runs the pointer cCurrentGameState-render(), etc. I want to make a transitioning game, this engine should ideally cover both a platformer and a bird's eye RPG (with some recoding, I just mean the base engine), both of which will load different levels and events, such as world map, dungeon, shops, etc. So I then thought, rather then having to store all this data within all the states, I would break the engine into gameStates, and playStates... when gameState reaches gameStatePlay(), gameStatePlay simply runs the usual handleInput, logic, and render for the playStates, just as the low level gameStateManager does. This lets me store all the player data within the base playstate class without storing useless data in the gameStates. Now I have added a seperate mapEditor, which uses editorStates from gameStateEditor. Is this too much usage of the gameState concept? It seems to work pretty well for me, so I was wondering if I am too far off a common implementation of this. My second question is on image resources. I have my sprite class with nothing but static members, mainly loadImage, applySurface, and my screen pointer. I also have a map pairing imageName enums with actual SDL_Surface pointers, and one pairing clipNumber enums with a wrapper class for a vector of clips, so that each reference in the map can have different amounts of clips with different sizes. I thought it would be better to store all these images, and screen within one static body, since 20 different goblins all use the same sprite sheet, and all need to print to the same screen, and of course, this way I do not need to pass my screen reference to every little entity. The imageMap seems to work very well, I can even add the ability to search through the map at creation of entity type to see if a particular image at creation, creating if it doesnt exist, and destroying the image if the last entity that needs it was just destroyed. The vectored clip map however, seems to take too long to initialize, so if i run past the state that initializes them to fast, the game crashes <. Plus, the clip map call is half of this line =P SPRITE::applySurface( cEditorMap.cTiles[x][y].iX, cEditorMap.cTiles[x][y].iY, SPRITE::mImages[ IMAGE_TILEMAP ], SPRITE::screen, SPRITE::mImageClips[IMAGE_TILEMAP]->clips.at( cEditorMap.cTiles[x][y].iTileType ) ); Again, do I have the right idea? I like the imageMap, but am I better off with each entity storing its own clips? My last question is about collision detection. I only grasp the basics, will look at per-pixel and circular soon, but how can I determine which side the collision comes from with just the basic square collision detection, I tried breaking each entity into 4 collision zones, but that just gave me problems with walking through walls and the like <. Also, is per-pixel color collision a good way to decide what collision just occured, or is checking multiple colors for multiple entities too taxing each cycle?

• Why does creating dynamic bodies in JBox2D freeze my app?

  - by Amplify91

  My game hangs/freezes when I create dynamic bullet objects with Box2D and I don't know why. I am making a game where the main character can shoot bullets by the user tapping on the screen. Each touch event spawns a new FireProjectileEvent that is handled properly by an event queue. So I know my problem is not trying to create a new body while the box2d world is locked. My bullets are then created and managed by an object pool class like this: public Projectile getProjectile(){ for(int i=0;i<mProjectiles.size();i++){ if(!mProjectiles.get(i).isActive){ return mProjectiles.get(i); } } return mSpriteFactory.createProjectile(); } mSpriteFactory.createProjectile() leads to the physics component of the Projectile class creating its box2d body. I have narrowed the issue down to this method and it looks like this: public void create(World world, float x, float y, Vec2 vertices[], boolean dynamic){ BodyDef bodyDef = new BodyDef(); if(dynamic){ bodyDef.type = BodyType.DYNAMIC; }else{ bodyDef.type = BodyType.STATIC; } bodyDef.position.set(x, y); mBody = world.createBody(bodyDef); PolygonShape dynamicBox = new PolygonShape(); dynamicBox.set(vertices, vertices.length); FixtureDef fixtureDef = new FixtureDef(); fixtureDef.shape = dynamicBox; fixtureDef.density = 1.0f; fixtureDef.friction = 0.0f; mBody.createFixture(fixtureDef); mBody.setFixedRotation(true); } If the dynamic parameter is set to true my game freezes before crashing, but if it is false, it will create a projectile exactly how I want it just doesn't function properly (because a projectile is not a static object). Why does my program fail when I try to create a dynamic object at runtime but not when I create a static one? I have other dynamic objects (like my main character) that work fine. Any help would be greatly appreciated. This is a screenshot of a method profile I did: Especially notable is number 8. I'm just still unsure what I'm doing wrong. Other notes: I am using JBox2D 2.1.2.2. (Upgraded from 2.1.2.1 to try to fix this problem) When the application freezes, if I hit the back button, it appears to move my game backwards by one update tick. Very strange.

• What are the drawbacks of sending XML to browsers and let them apply XSLT?

  - by MainMa

  Context Working as a freelance developer, I often made websites completely based on XSLT. In other words, on every request, an XML file is generated, containing everything we need to know about the page content: the name of the user currently logged in, the top menu entries, if this menu is dynamic/configurable, the text to display in a specific area of the page, etc. Then XSL process (caches, etc.) it to HTML/XHTML page to send to the browser. It has a good point to make it easier to create small-scale websites, especially with PHP. It is a sort of template engine, but which I prefer to other template engines because it's much more powerful than most of template engines, and because I know it better and like it. It is also possible, when need, to give an access to raw XML data on demand for an automated access, without the need to create separate APIs. Of course, it will fail completely on any medium-scale or large-scale website, since, even with good caching techniques, XSL still degrades overall website performance and requires more CPU serverside. Question Modern browsers have the ability to take an XML file and to transform it with an associated XSL file declared in XML like <?xml-stylesheet href="demo.xslt" type="text/xsl"?>. Firefox 3 can do it. Internet Explorer 8 can do it too. It means that it is possible to migrate XSL processing from the server to the client side for 50% of users (according on browser statistics on several websites where I may want to implement this). It means that those 50% of users will receive only the XML file at each request, thus reducing their and server's bandwidth (XML file being much shorter than its processed HTML analog), and reducing server's CPU usage. What are the drawbacks of this technique? I thought about several ones, but it doesn't apply in this situation: Difficult implementation and the need to choose, based on the browser request, when to send raw XML and when to transform it to HTML instead. Obviously, the system will not be much more difficult then the actual one. The only change to make is to add XSL file link to every XML, and to add a browser check. More IO and bandwidth usage, since the XSLT file will be downloaded by the browsers, instead of being cached by the server. I don't think it will be a problem, since XSLT file will be cached by the browsers (like images, or CSS, or JavaScript files are cached actually). Possibly some problems on client side, like maybe problems when saving a page in some browsers. Difficulty to debug code: it is impossible to obtain an HTML source the browser is actually using, since the only displayed source is the downloaded XML. On the other hand, I rarely go look at HTML code on client side, and in most cases, it is unusable directly (whitespace being removed).

• Achieving decoupling in Model classes

  - by Guven

  I am trying to test-drive (or at least write unit tests) my Model classes but I noticed that my classes end up being too coupled. Since I can't break this coupling, writing unit tests is becoming harder and harder. To be more specific: Model Classes: These are the classes that hold the data in my application. They resemble pretty much the POJO (plain old Java objects), but they also have some methods. The application is not too big so I have around 15 model classes. Coupling: Just to give an example, think of a simple case of Order Header - Order Item. The header knows the item and the item knows the header (needs some information from the header for performing certain operations). Then, let's say there is the relationship between Order Item - Item Report. The item report needs the item as well. At this point, imagine writing tests for Item Report; you need have a Order Header to carry out the tests. This is a simple case with 3 classes; things get more complicated with more classes. I can come up with decoupled classes when I design algorithms, persistence layers, UI interactions, etc... but with model classes, I can't think of a way to separate them. They currently sit as one big chunk of classes that depend on each other. Here are some workarounds that I can think of: Data Generators: I have a package that generates sample data for my model classes. For example, the OrderHeaderGenerator class creates OrderHeaders with some basic data in it. I use the OrderHeaderGenerator from my ItemReport unit-tests so that I get an instance to OrderHeader class. The problem is these generators get complicated pretty fast and then I also need to test these generators; defeating the purpose a little bit. Interfaces instead of dependencies: I can come up with interfaces to get rid of the hard dependencies. For example, the OrderItem class would depend on the IOrderHeader interface. So, in my unit tests, I can easily mock the behaviour of an OrderHeader with a FakeOrderHeader class that implements the IOrderHeader interface. The problem with this approach is the complexity that the Model classes would end up having. Would you have other ideas on how to break this coupling in the model classes? Or, how to make it easier to unit-test the model classes?

• Building a Solaris 11 repository without network connection

  - by user12611852

  Solaris 11 has been released and is a fantastic new iteration of Oracle's rock solid, enterprise operating system.  One of the great new features is the repository based Image Packaging system.  IPS not only introduces new cloud based package installation services, it is also integrated with our zones, boot environment and ZFS file systems to provide a safe, easy and fast way to perform system updates. My customers typically don't have network access and, in fact, can't connect to any network until they have "Authority to connect."  It's useful, however, to build up a Solaris 11 system with additional software using the new Image Packaging System and locally stored repository. The Solaris 11 documentation describes how to create a locally stored repository with full explanations of what the commands do. I'm simply providing the quick and dirty steps.  The easiest way is to download the ISO image, burn to a DVD and insert into your DVD drive.  Then as root: pkg set-publisher -G '*' -g file:///cdrom/sol11repo_full/repo solaris Now you can to install software using the GUI package manager or the pkg commands.  If you would like something more permanent (or don't have a DVD drive), however, it takes a little more work. After installing Solaris 11, download (on another system perhaps) the two files that make up the Solaris 11 repository from our download site Sneaker-net the files to your Solaris 11 system Unzip and cat the two files together to create one large ISO image. The file is about 6.9 GB in size zfs create rpool/export/repoSolaris11 zfs set atime=off rpool/export/repoSolaris11 zfs set compression=on rpool/export/repoSolaris11 (save some space) lofiadm -a sol-11-1111-repo-full.iso /dev/lofi/1 mount -F hsfs /dev/lofi/1 /mnt You could stop here and set the publisher to point to the /mnt/repo location, however, this mount will not be persistent across reboots. Copy the repository from the mounted ISO image to a permanent, on disk location. rsync -aP /mnt/repo /export/repoSolaris11 pkgrepo -s /export/repoSolaris11 refresh pkg set-publisher -G '*' -g /export/repoSolaris11/repo solaris You now have a locally installed repository for adding additional software packages for Solaris 11.  The documentation also takes you through publishing your repository on the network so that others can access it.

• Career Change Need Advice: Professional Web Developer

  - by bikedorkseattle

  I'm hoping to get some advice here on the steps I should take to make a career change into professional web development. I've been working in cancer research the last 14 years and I need a change. The job market is terrible, the pay is worse, and despite what one would think the atmosphere is generally un-collegial, even in your own group. Venture funding never returned after the dot com burst and with 3 to 5 wars our country is now in, NIH funding is only going to get worse. I know things are not going to get better for my field, sadly, and I know I need to move on. For probably just as long I have fiddled around with web development, I even run a fairly popular site with close to 1 million/month pageviews that pulls a decent income, but not stable enough to live off of right now. My skills are ok for being self taught. I enjoy the fast paced nature of the web and the tools the community creates and how eager people are to help and share knowledge; it's what science should be. I have been trying to find an entry level developer job doing standard HTML/CSS/PHP/MySQL/JS/jQuery type work. A good 50%+ of the jobs want someone with a CS degree, and most want 5 years experience. Having no professional experience and no formal education, I know I'm at a huge disadvantage. I am now considering my options on how to move forward professionally. The way I see it I have basically 3 options. Build up my portfolio of work as much as I can and continue to learn as much as I can on my own. Try to contribute on some open source project when time allows. Network like crazy and go to meetups. Be confident and pray a lot in private. OR While doing above, do some certification programs in PHP and Java, possibly others. Get a Zend Certification. OR Spend a few years getting a CS degree while doing 1. I've already done the work fulltime go to school thing and it doesn't excite me one bit. I didn't have the greatest college experience and am not too eager to return, but I have a family to feed. Is the degree really necessary or is it more of a right of passage type thing in most instances? I appreciate everyones input. Thanks for taking the time to respond.

• Event Driven Behavior Tree: deterministic traversal order with parallel

  - by Heisenbug

  I've studied several articles and listen some talks about behavior trees (mostly the resources available on AIGameDev by Alex J. Champandard). I'm particularly interested on event driven behavior trees, but I have still some doubts on how to implement them correctly using a scheduler. Just a quick recap: Standard Behavior Tree Each execution tick the tree is traversed from the root in depth-first order The execution order is implicitly expressed by the tree structure. So in the case of behaviors parented to a parallel node, even if both children are executed during the same traversing, the first leaf is always evaluated first. Event Driven BT During the first traversal the nodes (tasks) are enqueued using a scheduler which is responsible for updating only running ones every update The first traversal implicitly produce a depth-first ordered queue in the scheduler Non leaf nodes stays suspended mostly of the time. When a leaf node terminate(either with success or fail status) the parent (observer) is waked up allowing the tree traversing to continue and new tasks will be enqueued in the scheduler Without parallel nodes in the tree there will be up to 1 task running in the scheduler Without parallel nodes, the tasks in the queue(excluding dynamic priority implementation) will be always ordered in a depth-first order (is this right?) Now, from what is my understanding of a possible implementation, there are 2 requirements I think must be respected(I'm not sure though): Now, some requirements I think needs to be guaranteed by a correct implementation are: The result of the traversing should be independent from which implementation strategy is used. The traversing result must be deterministic. I'm struggling trying to guarantee both in the case of parallel nodes. Here's an example: Parallel_1 -->Sequence_1 ---->leaf_A ---->leaf_B -->leaf_C Considering a FIFO policy of the scheduler, before leaf_A node terminates the tasks in the scheduler are: P1(suspended),S1(suspended),leaf_A(running),leaf_C(running) When leaf_A terminate leaf_B will be scheduled (at the end of the queue), so the queue will become: P1(suspended),S1(suspended),leaf_C(running),leaf_B(running) In this case leaf_B will be executed after leaf_C at every update, meanwhile with a non event-driven traversing from the root node, the leaf_B will always be evaluated before leaf_A. So I have a couple of question: do I have understand correctly how event driven BT work? How can I guarantee the depth first order is respected with such an implementation? is this a common issue or am I missing something?

• What to do when you inherit an unmaintainable codebase?

  - by GordonM

  I'm currently working at a company with 2 other PHP developers aside from me, and 1 junior developer. The senior developer who originally built the system we're all working on has resigned and will only be here for a matter of weeks. The other developer, who is the only other guy who knows anything about the system, is unhappy here and is looking for a new job. I'm very real danger of being left behind as the only experienced developer on this codebase. Since I've joined this company I've tried to push for better coding standards, project documentation, etc and I do think I've made some headway, but the vast majority of the code is simply unmaintainable and uncommented. A lot of this has to do with the need to get things done fast at points in the project before I joined, but now the technical debt is enormous, even with the two developers who do understand the system on board. Without them, it will simply be impossible to do anything with it. The senior developer is working on trying to at least comment all his code before he leaves but I think the codebase is simply too vast to properly document in the remaining time. Besides, when he does comment it still doesn't make things as clear as it could. If the system was better organized and documented I could probably start refactoring it incrementally, but the whole thing is so tightly coupled that it's very difficult to make any changes in one module without having unintended knock-on effects in other modules. Naturally, there's no unit tests either, and I honestly don't think this codebase could possibly be unit tested anyway given how it's implemented. There also never seems to be enough time to get things done even with 3 developers and 1 junior developer. With one developer and one junior, neither of which had significant input into the early design of the system, I don't see how we could possibly get anything done with keeping the current system working, implementing new features as needed and developing a replacement for the current codebase that is better organized. Is there an approach I can take to cope with this situation, or should I be getting my own CV in order as well at this point? If it was just me and the junior designer who would be left I'd go for the latter option almost without question. However, there's a team of front-end developers and content managers as well, and I'm worried what would become of them if I left and put them in a position where there would be no developers at all. The department might just be closed down altogether under such circumstances, and then I'd have their unemployment on my conscience as well!

• PeopleSoft Grants & the Federal Agency Letter of Credit Draw Changes

  - by Mark Rosenberg

  For decades, most, if not all, US Federal agencies that sponsor research allowed grant recipients to request and receive payments using pooled accounts, commonly known as pooled letter of credit (LOC) draws. This enabled organizations, such as universities and hospitals, fast and efficient access to reimbursement of the expenditures they incurred conducting research across a portfolio of grants. To support this business practice, the PeopleSoft Grants solution has delivered an LOC Draw report to provide the total request amount along with all of the supporting invoice details for reconciliation and audit purposes. Now, in an attempt to provide greater transparency, eliminate fraud, strengthen accountability for grant-related financial transactions, and simplify grant award closeout, many US Federal sponsors are transitioning from the “pooling” letter of credit draw method to requesting on a “grant-by-grant” basis. The National Science Foundation, the second largest issuer of Federal awards, already transitioned to detailed grant draws in 2013. And, in response to the U.S. Department of Health and Human Services (HHS) directive to HHS-supported Agencies, the largest Federal awards sponsor, the National Institutes of Health (NIH), will fully transition to the new HHS subaccount draw method. This will require NIH award recipients to request payments based on actual expenses incurred on an award-by-award basis. NIH is expected to fully transition to this new draw method by the end of Federal fiscal year 2015.  (The NIH had planned to fully transition to this new method by the end of fiscal 2014; however, the impact to institutions was deemed to be significant enough that a reprieve was recently granted.) In light of these new Federal draw requirements, we have recently released these new features to aid our customers on both PeopleSoft Grants releases 9.1 and 9.2:1. Federal Award Identification Number on the Proposal and Award Profile 2. Letter of credit fields on contract lines to support award basis draws and comply with Federal close out mandates3. Process to produce both pro forma and final LOC Draw Reports in BI Publisher report format4. Subacccount ID field on the LOC Summary and a new BI Publisher version of the LOC Summary report 5. Added Subaccount Field and contract info to be displayed on the LOC summary page6. Ability to generate by a variety of dimensions pro forma and invoiced draw listings 7. Queries for generation and manipulation of data to upload into sponsor payment request systems and perform payment matching8. Contracts LOC Close Out query to quickly review final balances prior to initiating final draws and preparing Federal Financial Reports prior to close The PeopleSoft Development team actively monitors this and other major Federal changes and continues working closely with the Grants Product Advisory Group of the Higher Education User Group to ensure a clear understanding of what our customers need in order to transition to new approaches for doing business with the Federal government. For more information regarding the enhancements to the PeopleSoft Grants solution, existing customers can login to My Oracle Support and review the Enhancements to Letter of Credit Process (Doc ID 1912692.1) associated with resolution ID 904830. This enhanced LOC functionality is available in both PeopleSoft FSCM 9.1 Bundle #31 and PeopleSoft FSCM 9.2 Update Image 8.

• What is 'Ubuntu Unity' (for the Desktop)?

  - by Martin

  Ok, so there's the buzz of Canonical (wanting to) switch for new Ubuntu version from the GNOME default desktop to their own Unity shell. (I hope that's accurate.) It seems I can not totally fathom what Unity actually is. For looking at its homepage it currently is firmly targeted at netbooks and the somehow different usage model on these. Is it a classical desktop? -- Taskbar? Shortcuts? Is the difference between Ubuntu(GNOME)+Unity more/less pronounced than the difference between Ubuntu and Kubuntu? Will "my parents" be able to get the interface if they've been using the classical gnome desktop so far? Edit: I would not like to split this up into more specific questions, as What is Unity? is exactly what the people I set up Ubuntu boxes for will ask me if they hear that the newer Ubuntu version is using that instead of the Desktop -- and it might well happen someone phrases it like that :-) I will certainly not give them the link to the HP as the explanation there does not lay out if it is a desktop or something more or something less: (It does not for me - therefore I'm asking here.) Unity is designed for netbooks and related touch-based devices. It includes [...] that makes it fast and easy to access [...] while removing screen elements that are rarely used in mobile and netbook computing. (emphasis mine) -- the explanation there doesn't even mention the desktop-PC! Unity has a vertical task management panel on the left-hand side and a menu panel at the top of the screen. [...] This sounds like a re-themed normal desktop. Clicking on an icon will give the target application focus if it is already running or launch it if it is not already running. If you click the ... Aha. Sounds like Windows 7. ... icon of an application that already has focus, Unity will activate an Expose-style view of all the open windows associated with that application. No clue what that's supposed to be. So it would really be nice if someone could explain for non desktop-design-terms experts what Unity is.

• How can I achieve a 3D-like effect with spritebatch's rotation and scale parameters

  - by Alic44

  I'm working on a 2d game with a top-down perspective similar to Secret of Mana and the 2D Final Fantasy games, with one big difference being that it's an action rpg using a 3-dimensional physics engine. I'm trying to draw an aimer graphic (basically an arrow) at my characters' feet when they're aiming a ranged weapon. At first I just converted the character's aim vector to radians and passed that into spritebatch, but there was a problem. The position of every object in my world is scaled for perspective when it's drawn to the screen. So if the physics engine coordinates are (1, 0, 1), the screen coords are actually (1, .707) -- the Y and Z axis are scaled by a perspective factor of .707 and then added together to get the screen coordinates. This meant that the direction the aimer graphic pointed (thanks to its rotation value passed into spritebatch) didn't match up with the direction the projectile actually traveled over time. Things looked fine when the characters fired left, right, up, or down, but if you fired on a diagonal the perspective of the physics engine didn't match with the simplistic way I was converting the character's aim direction to a screen rotation. Ok, fast forward to now: I've got the aimer's rotation matched up with the path the projectile will actually take, which I'm doing by decomposing a transform matrix which I build from two rotation matrices (one to represent the aimer's rotation, and one to represent the camera's 45 degree rotation on the x axis). My question is, is there a way to get not just rotation from a series of matrix transformations, but to also get a Vector2 scale which would give the aimer the appearance of being a 3d object, being warped by perspective? Orthographic perspective is what I'm going for, I think. So, the aimer arrow would get longer when facing sideways, and shorter when facing north and south because of the perspective. At the same time, it would get wider when facing north and south, and less wide when facing right or left. I'd like to avoid actually drawing the aimer texture in 3d because I'm still using spritebatch's layerdepth parameter at this point in my project, and I don't want to have to figure out how to draw a 3d object within the depth sorting system I already have. I can provide code and more details if this is too vague as a question... This is my first post on stack exchange. Thanks a lot for reading! Note: (I think) I realize it can't be a technically correct 3D perspective, because the spritebatch's vector2 scaling argument doesn't allow for an object to be skewed the way it actually should be. What I'm really interested in is, is there a good way to fake the effect, or should I just drop it and not scale at all? Edit to clarify without the help of a picture (apparently I can't post them yet): I want the aimer arrow to look like it has been painted on the ground at the character's feet, so it should appear to be drawn on the ground plane (in my case the XZ plane) which should be tilted at a 45 degree angle (around the X axis) from the viewing perspective.

• Move Data into the Grid for Scalable, Predictable Response Times

  - by JuergenKress

  CloudTran is pleased to introduce the availability of the CloudTran Transaction and Persistence Manager for creating scalable, reliable data services on the Oracle Coherence In-Memory Data Grid (IMDG). Use of IMDG architectures has been key to handling today’s web-scale loads because it eliminates database latency by storing important and frequently access data in memory instead of on disk. The CloudTran product lets developers easily use an IMDG for full ACID-compliant transactions without having to be concerned about the location or spread of data. The system has its own implementation of fast, scalable distributed transactions that does NOT depend on XA protocols but still guarantees all ACID properties. Plus, CloudTran asynchronously replicates data going into the IMDG to back-end datastores and back-up data centers, again ensuring ACID properties. CloudTran can be accessed through Java Persistence API (JPA via TopLink Grid) and now, through a new Low-Level API, or LLAPI. This is ideal for use in SOA applications that need data reliability, high availability, performance, and scalability. Still in limited beta release, the LLAPI gives developers the ability to use standard put/remove logic available in Coherence and then wrap logic with simple Spring annotations or XML+AspectJ to start transactions. An important feature of LLAPI is the ability to join transactions. This is a common outcome for SOA applications that need to reduce network traffic by aggregating data into single cache entries and then doing SOA service processing in the node holding the data. This results in the need to orchestrate transaction processing across multiple service calls. CloudTran has the capability to handle these “multi-client” transactions at speed with no loss in ACID properties. Developing software around an IMDG like Oracle Coherence is an important choice for today’s web-scale applications and services. But this introduces new architectural considerations to maintain scalability in light of increased network loads and data movement. Without using CloudTran, developers are faced with an incredibly difficult task to ensure data reliability, availability, performance, and scalability when working with an IMDG. Working with highly distributed data that is entirely volatile while stored in memory presents numerous edge cases where failures can result in data loss. The CloudTran product takes care of all of this, leaving developers with the confidence and peace of mind that all data is processed correctly. For those interested in evaluating the CloudTran product and IMDGs, take a look at this link for more information: http://www.CloudTran.com/downloadAPI.php, or, send your questions to [email protected].

• When a problem is resolved

  - by Rob Farley

  This month’s T-SQL Tuesday is hosted by Jen McCown, and she’s picked the topic of Resolutions. It’s a new year, and she’s thinking about what people have resolved to do this year. Unfortunately, I’ve never really done resolutions like that. I see too many people resolve to quit smoking, or lose weight, or whatever, and fail miserably. I’m not saying I don’t set goals, but it’s not a thing for New Year. The obvious joke is “1920x1080” as a resolution, but I’m not going there. I think Resolving is a strange word. It makes it sound like I’m having to solve a problem a second time, when actually, it’s more along the lines of solving a problem well enough for it to count as finished. If something has been resolved, a solution has been provided. There is a resolution, through the provision of a solution. It’s a strangeness of English. When I look up the word resolution at dictionary.com, it has 12 options, including “settling of a problem”. There’s a finality about resolution. If you resolve to do something, you’re saying “Yes. This is a done thing. I’m resolving to do it, which means that it may as well be complete already.” I like to think I resolve problems, rather than just solving them. I want my solving to be final and complete. If I tune a query, I don’t want to find that I’m back in there, re-tuning it at some point. Strangely, if I re-solve a problem, that implies that I didn’t resolve it in the first place. I only solved it. Temporarily. We “data-folk” live in a world where the most common answer is “It depends.” Frustratingly, the thing an answer depends on may still be changing in the system in question. That probably means that any solution that is put in place may need reinvestigating at some point later. So do I resolve things? Yes. Am I Chuck Norris, and solve things so well the world would break first? No. Do these two claims happily sit beside each other? No, unfortunately not. But I happily take responsibility for things, and let my clients depend on me to see it through. As far as they are concerned, it is resolved. And so I resolve to keep resolving, right through 2011.

• SOA Summit - Oracle Session Replay

  - by Bruce Tierney

  If you think you missed the most recent Integration Developer News (IDN) "SOA Summit" 2013...good news, you didn't.  At least not the replay of the Oracle session titled: Three Solutionsfor Simplifying Cloud/On-Premises Integration As you will see in the reply below, this session introduces Three common reasons for integration complexity: Disparate Toolkits Lack of API Management Rigid, Brittle Infrastructure and then the Three solutions to these challenges: Unify Cloud On-premises Integration Enable Multi-channel Development with API Management Plan for the Unexpected - Future Readiness The last solution on future readiness describes how you can transition from being reactive to new trends, such as the Internet of Things (IoT), by modifying your integration strategy to enable business agility and how to recognize trends through Fast Data event processing ahead of your competition. Oracle SOA Suite customer SFpark's (San Francisco Metropolitan Transit Authority) implementation with API Management is covered as shown in the screenshot to the right This case study covers the core areas of API Management for partners to build their own applications by leveraging parking availability and real-time pricing as well as mobile enablement of data integrated by SOA Suite underneath.  Download the free SFpark app from the Apple and Android app stores to check it out. When looking into the future, the discussion starts with a historical look to better prepare for what comes next.   As shown in the image below, one of the next frontiers after mobile and cloud integration is a deeper level of direct "enterprise to customer" interaction.  Much of this relates to the Internet of Things.  Examples of IoT from the perspective of SOA and integration is also covered in the session. For example, early adopter Turkcell and their tracking of mobile phone users as they move from point A to B to C is shown in the image the right.   As you look into more "smart services" such as Location-Based Services, how "future ready" is your application infrastructure?  . . . Check out the replay by clicking the video image below to learn about these three challenges and solution including how to "future ready" your application infrastructure:
