  • The JDEdwards EnterpriseOne PreSales University

    - by Julien Haye
    Istanbul NOV 5-9 Wednesday, NOV 7 - It is raining outside and I am sitting in my hotel room (#106) in Istanbul and create my first blog entry. Today this blog was enabled and I am excited to have the ability to share my (first) thoughts with the EMEA JDE Partner Community. I am here in Istanbul because we are currently running the JDEdwards PreSales University Event series. This PreSales University is an established event series which we deliver the fifth time now and the first time in the ECEMEA region. Delegates value the openness and competence from the Product Strategy and Product Development Team from Denver and India. Together with the regional Oracle PreSales team we had very valuable discussions around product features and functions and about the business value of the new delivered applications and tools. Additionally the event provides endless opportunities to exchange ideas with other JD Edwards Partner and the Oracle PreSales Team. With its focus on sharing and learning, best practice, user experience and transforming technologies, delegates will leave this event with an abundance of new ideas and best practices to try for your coming projects and existing customer implementations. A day out of the office gives delegates a chance to gain a new perspective on their business processes. Everybody sees better ways of working just by being immersed in an environment where the focus is on using products more effectively. Apps Track: Highly concentrated participants in Istanbul listening to Jeff Erickson presenting the news about OneView Reporting. Jeff: We believe “The things you said”. The event is organized into two tracks, one for Apps and one for Tech. Everybody was able to learn new features and functions and how to position this products. The focus was on the new Apps release 9.1 and Tools Release 9.1.2 and their Value Propositions. For all topics hands-on exercises has been given to the participants. Even very experienced senior consultants did learn a lot from this event. In total we have 55 people registered and we still have some more content to deliver. By the way: Istanbul is a nice place to be. I already booked my next trip to this beautiful city. In two weeks we deliver the JD Edwards EECIS Executive Forum again in Istanbul. Once again a tough Agenda. I will let you know if I had the ability to have a walk outside and see a bit more of this beautiful city. At least I expect to have a different room number. Many greetings Hartmut WieseOracle Alliances & Channels EMEA

  • Data Generator Source Adapter

    This component needs little explanation. It generates random integer (DT_I4) and string (DT_WSTR) data and places them in the pipeline. You specify how many columns of each you would like and for any string columns you pass a fixed length value. You then need to specify how many rows in total you require to be generated. This component is used by us to do testing of the pipeline and components downstream. Previously we would have used a script component (as a source) to generate the rows but found ourselves rewriting the code too often so created this component. Screenshots SQL Server 2005 Integration Services SQL Server 2008/2012 Integration Services The component is provided as an MSI file, however to complete the installation, you will have to add the transformation to the Visual Studio toolbox manually. Right-click the toolbox, and select Choose Items.... Select the SSIS Data Flow Items tab, and then check the Data Generator Source from the list. Downloads The Data Generator Source Adapter is available for SQL Server 2005, SQL Server 2008 (includes R2) and SQL Server 2012. Please choose the version to match your SQL Server version, or you can install multiple versions and use them side by side if you have more than one version of SQL Server installed.

  • Atheros AR928X wireless connection makes neighbourhood machine drop off line

    - by funicorn
    I have an Acer laptop with Atheros AR928X wireless card installed, supported by ath9k driver in the linux kernel. There are other 5 computers sharing wireless connection via a TPLink 150Mbit/s wireless router. At first I found the network is a little bit slower than it's in Windows7, which I accepted as it should be. However a very strange thing is, each time I connected to the router and downloaded stuff for a while, one of the computers running Windows7 in my local network dropped off from the router. And if I run my laptop under Windows7, everything is fine. What's even stranger is although the network becomes slower, only the certain computer drops and totally freezes in connection with the router. I'm not willing to conclude it's due to the unhealthy connection from my laptop to the router, however we have confirmed this for more than one times and there is no problem with the network when I'm running WIndows7. I'm extremely confused about what's going on. As a Linux user running Ubuntu over 5 years, I am awared that wireless driver in Linux is badly notorious of lack of stability and slow speed. But is it so bad that the unhealthy wireless connection can do damage to another computer in the same local network? I do see a lot of "Tx excessive retries" in iwconfig output. But how exactly does this happen ? Thanks for your help. I guess I have to use this answer box to show the outputs $ sudo iwconfig wlan0 IEEE 802.11bgn ESSID:"TP-LINK111" Mode:Managed Frequency:2.427 GHz Access Point: E0:05:C5:E8:A9:92 Bit Rate=121.5 Mb/s Tx-Power=16 dBm Retry long limit:7 RTS thr:off Fragment thr:off Encryption key:off Power Management:off Link Quality=47/70 Signal level=-63 dBm Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0 Tx excessive retries:2 Invalid misc:23 Missed beacon:0 To show what's wrong with the wireless connection, I ran iwconfig again within 3 minutes, during which time I hardly did anything and the network was not much busy than being nearly idle $ sudo iwconfig wlan0 IEEE 802.11bgn ESSID:"TP-LINK111" Mode:Managed Frequency:2.427 GHz Access Point: E0:05:C5:E8:A9:92 Bit Rate=121.5 Mb/s Tx-Power=16 dBm Retry long limit:7 RTS thr:off Fragment thr:off Encryption key:off Power Management:off Link Quality=48/70 Signal level=-62 dBm Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0 Tx excessive retries:9 Invalid misc:28 Missed beacon:0 You can see Tx excessive retires and Invalid misc increase very quickly. $ sudo iwlist wlan0 modu wlan0 unknown modulation information. $ sudo iwlist wlan0 channel wlan0 13 channels in total; available frequencies : Channel 01 : 2.412 GHz Channel 02 : 2.417 GHz Channel 03 : 2.422 GHz Channel 04 : 2.427 GHz Channel 05 : 2.432 GHz Channel 06 : 2.437 GHz Channel 07 : 2.442 GHz Channel 08 : 2.447 GHz Channel 09 : 2.452 GHz Channel 10 : 2.457 GHz Channel 11 : 2.462 GHz Channel 12 : 2.467 GHz Channel 13 : 2.472 GHz Current Frequency:2.427 GHz (Channel 4)

  • Where can I hire local programmers with very specific skillsets?

    - by Lostsoul
    I have been browsing the site and haven't found a exact fit to this question so I'll post it but if its already answered(since I'm sure its a common problem, then let me know). I have a business and want to create a totally different product in a different industry than I'm currently in, so I learned how to program and created a working prototype. I have a bit of savings and am getting some cash flow from my current business so I can go out and hire a developer(in the future hopefully it can be permenant but right now I just need a person willing to work on contract and code on weekends or their spare time and I just want to pay in cash instead of equity or future promises). At first I wasn't sure what kind of developer to hire but this question helped me understand I should target specific skills I need as opposed to general programmers. This poses a problem for me since general programmers are everywhere but if I want specific skills I'm unsure how to get them. I thought about a list of approaches but it doesn't feel complete or effective since it seems to be assuming good developers are actively looking. If it helps I want someone local(since this is my first developer hire) and looking for skills like cuda, hadoop, hbase, java and c. Any suggestions? As a FYI, I have been thinking of approaching it as: Go to meet ups for one or more skills I need. Use LinkedIn to find people with the skills I need Search for job postings that contain skills I need and then use linkedIn to reach out to that firms employees since many profiles on linkedin are not very updated or detailed but job postings generally are. Send postings to universities and maybe find a student who loves technology so much they learned these tools on their own. Post on job board. Not sure how successful it will be to post to monster. Use Craigslist, not sure if a highly skilled developer would go here for work. What am I missing? I could be wrong but it seems like good/smart/able developers aren't hunting for work non-stop(especially in this tech job market). Plus most successful people I know have work/life balance so I'm not sure if the best ones really care about code after work. Lastly, most of the skills I need aren't used in big corporations so not sure how aggressively smart developers at small shops look for work. I don’t really know any developers personally, so but should I be using the above plan or if they live balanced lives should I be looking outside of the regular resources(and instead focus on asking around my gym or my accountant or something)? Sorry, I'm making huge assumptions here, I guess because developers are a total mystery to me. I kind of wish Jane Goodall wrote a book on understanding developers social behaviour better :-p

  • Cannot get 3D OpenGL support in Vmware guests, how can I fix this?

    - by jjapol
    I have been working at this problem for 2 days now. I cannot for the life of me enable 3D support in VMWare 9 guests. My specifications are: Hardware: Dell Latitude E5520 laptop. Processor: Intel i7-2620M CPU @ 2.70GHz × 4. Memory: 8GB. Video: Intel Sandybridge Mobile x86/MMX/SSE2 OS: Ubuntu 12.04.1 LTS, 32 bit. Vmware Workstation: 9.0.1 build-894247 Glxgears functions fine. Frame rate is ~60fps. Vmware guest: Windows 7 Starting the Windows 7 guest in VMware throws the following errors: No 3D support is available from the host. and Hardware graphics acceleration is not available. I've read through this VMware forum thread, but again the hardware in the post is different (nVidia). I've followed the instructions at this Ask Ubuntu post as closely as possible as the question is nearly the same as mine although my hardware is different. Answer 1 regarding setting mks.gl.allowBlacklistedDrivers = TRUE; in my vmx configuration file causes the VM to crash when it starts. The second answer I followed as closely as possible. I uninstalled VMware, Did sudo apt-get install build-essential linux-headers-$(uname -r) at a terminal, Added the PPA https://launchpad.net/~glasen/+archive/intel-driver, Then at a terminal did sudo apt-get update && sudo apt-get upgrade -y I reinstalled VMware and have the same results: no 3D in guests. I'm getting the feeling that something is awry with the Sandy Bridge driver, but I can't seem to come up with any solutions. Has anyone out there run across this problem also? By the way, the operation of the likes of Solidworks and AutoCad within a Windpws 7 guest does appear to be improved in VMware 9 vs VMware 8 in spite of the fact that 3D support is lacking in the Windows 7 guest. I'd also add that my glxinfo file was nearly identical to the glxinfo file posted at askubuntu.com/questions/181829/…. I had a total of seven minor differences per a comparison using Meld. –

  • Problems with moving 2D circle/box collision detection

    - by dario3004
    This is my first game ever and I'm a newbie in computer physics. I've got this code for the collision detection and it works fine for BOTTOM and TOP collision.It miss the collision detection with the paddle's edge and angles so I've (roughly) tried to implement it. Main method that is called for bouncing, it checks if it bounce with wall, or with top (+ right/left side) or with bottom (+ right/left side): protected void handleBounces(float px, float py) { handleWallBounce(px, py); if(mBall.y < getHeight()/4){ if (handleRedFastBounce(mRed, px, py)) return; if (handleRightSideBounce(mRed,px,py)) return; if (handleLeftSideBounce(mRed,px,py)) return; } if(mBall.y > getHeight()/4 * 3){ if (handleBlueFastBounce(mBlue, px, py)) return; if (handleRightSideBounce(mBlue,px,py)) return; if (handleLeftSideBounce(mBlue,px,py)) return; } } This is the code for the BOTTOM bounce: protected boolean handleRedFastBounce(Paddle paddle, float px, float py) { if (mBall.goingUp() == false) return false; // next position tx = mBall.x; ty = mBall.y - mBall.getRadius(); // actual position ptx = px; pty = py - mBall.getRadius(); dyp = ty - paddle.getBottom(); xc = tx + (tx - ptx) * dyp / (ty - pty); if ((ty < paddle.getBottom() && pty > paddle.getBottom() && xc > paddle.getLeft() && xc < paddle.getRight())) { mBall.x = xc; mBall.y = paddle.getBottom() + mBall.getRadius(); mBall.bouncePaddle(paddle); playSound(mPaddleSFX); increaseDifficulty(); return true; } else return false; } As long as I understood it should be something like this: So I tried to make the "left side" and "right side" bounce method: protected boolean handleLeftSideBounce(Paddle paddle, float px, float py){ // next position tx = mBall.x + mBall.getRadius(); ty = mBall.y; // actual position ptx = px + mBall.getRadius(); pty = py; dyp = tx - paddle.getLeft(); yc = ty + (pty - ty) * dyp / (ptx - tx); if (ptx < paddle.getLeft() && tx > paddle.getLeft()){ System.out.println("left side bounce1"); System.out.println("yc: " + yc + "top: " + paddle.getTop() + " bottom: " + paddle.getBottom()); if (yc > paddle.getTop() && yc < paddle.getBottom()){ System.out.println("left side bounce2"); mBall.y = yc; mBall.x = paddle.getLeft() - mBall.getRadius(); mBall.bouncePaddle(paddle); playSound(mPaddleSFX); increaseDifficulty(); return true; } } return false; } I think I'm quite near to the solution but I'm having big troubles with the new "yc" formula. I tried so many versions of it but since I don't know the theory behind it I can't adjust for the Y axis. Since the Y axis is inverted I even tried this: yc = ty - (pty - ty) * dyp / (ptx - tx); I tried Googling it but I can't seem to find a solution for it. Also this method fails when ball touches the angle and I don't think is a nice way because it just test "one" point of the ball and probably there will be many cases in which the ball won't bounce.

  • Survey results: Open source developer preferences

    We recently conducted a survey of open source developers to learn about their current preferences around hosting sites and source control systems.  The survey was primarily advertised via Twitter, and we tried to avoid pushing the survey among audiences that would be specifically oriented towards a particular site (for example we did not advertise the survey from the CodePlex twitter account). In total there were just under 500 responses, so a reasonable sample size although not necessarily enough to guarantee fully representative results.  One of the survey questions was what is your preferred operating system for development, and looking at the results they are particularly interesting when split by operating system preference because of how significant the difference is:   Table 1 - Preferences by what is preferred operating system for development   As you can see, the preferences among developers which prefer Windows is very different from Linux and Mac oriented developers.  Again, the question was on what operating system they prefer to use for development, and didn’t ask what type of applications they create, so presumably many create things like websites which are cross-platform from a user perspective regardless of the operating system they prefer developing with. For hosting site preference, CodePlex and GitHub are roughly tied for first place among Windows developers and combined are preferred by over 75%.  However with Linux and Mac developers, GitHub has a runaway lead over the other sites.  Perhaps not particularly surprising, CodePlex has negligible mindshare among Linux and Mac developers.  It is somewhat surprising how low SourceForge and Google Code are given historically they used to rank much higher. Looking at version control preferences is also interesting.  Among Windows developers TFS, Mercurial, Subversion, and Git all have a sizable following.  While for Linux and Mac developers it is almost all Git and Mercurial, with Git having a substantial lead.  Git is generally considered to run better on Linux and have more of a Unix feel, so not really surprising to see it more popular there compared to Windows developers.  It is surprising how low Subversion has dropped since it was the dominant preference not long ago for open source developers.  Around a quarter of Windows developers still prefer Subversion, but Linux and Mac developers have largely abandoned it.  The trend towards distributed version control systems (e.g. Mercurial and Git) is strong, with over 50% of Windows developers now prefer DVCS, and over 80% of Linux and Mac developers.

  • How do I cap rendering of tiles in a 2D game with SDL?

    - by farmdve
    I have some boilerplate code working, I basically have a tile based map composed of just 3 colors, and some walls and render with SDL. The tiles are in a bmp file, but each tile inside it corresponds to an internal number of the type of tile(color, or wall). I have pretty basic collision detection and it works, I can also detetc continuous presses, which allows me to move pretty much anywhere I want. I also have a moving camera, which follows the object. The problem is that, the tile based map is bigger than the resolution, thus not all of the map can be displayed on the screen, but it's still rendered. I would like to cap it, but since this is new to me, I pretty much have no idea. Although I cannot post all the code, as even though I am a newbie and the code pretty basic, it's already quite a few lines, I can post what I tried to do void set_camera() { //Center the camera over the dot camera.x = ( player.box.x + DOT_WIDTH / 2 ) - SCREEN_WIDTH / 2; camera.y = ( player.box.y + DOT_HEIGHT / 2 ) - SCREEN_HEIGHT / 2; //Keep the camera in bounds. if(camera.x < 0 ) { camera.x = 0; } if(camera.y < 0 ) { camera.y = 0; } if(camera.x > LEVEL_WIDTH - camera.w ) { camera.x = LEVEL_WIDTH - camera.w; } if(camera.y > LEVEL_HEIGHT - camera.h ) { camera.y = LEVEL_HEIGHT - camera.h; } } set_camera() is the function which calculates the camera position based on the player's positions. I won't pretend I know much about it. Rectangle box = {0,0,0,0}; for(int t = 0; t < TOTAL_TILES; t++) { if(box.x < (camera.x - TILE_WIDTH) || box.y > (camera.y - TILE_HEIGHT)) apply_surface(box.x - camera.x, box.y - camera.y, surface, screen, &clips[tiles[t]]); box.x += TILE_WIDTH; //If we've gone too far if(box.x >= LEVEL_WIDTH) { //Move back box.x = 0; //Move to the next row box.y += TILE_HEIGHT; } } This is basically my render code. The for loop loops over 192 tiles stored in an int array, each with their own unique value describing the tile type(wall or one of three possible colored tiles). box is an SDL_Rect containing the current position of the tile, which is calculated on render. TILE_HEIGHT and TILE_WIDTH are of value 80. So the cap is determined by if(box.x < (camera.x - TILE_WIDTH) || box.y > (camera.y - TILE_HEIGHT)) However, this is just me playing with the values and see what doesn't break it. I pretty much have no idea how to calculate it. My screen resolution is 1024/768, and the tile map is of size 1280/960.

  • Cloning a dual boot system from HDD to SSD

    - by Alex
    I'm planning on replacing my laptop's HDD with a 256GB SSD, but I have a dual-boot (12.04 and Windows 7) setup and I'd like to be able to directly migrate Ubuntu over without having to reinstall and lose all of my settings. GParted reports the following partition setup on my HDD. I am, of course, able to modify it if necessary. /dev/sda1 (NTFS) 66.92 out of 200.00 MB used I'm honestly not sure what this partition is for. Maybe for Windows 7 system files? I'm hesitant to mess with it. (edit; it turns out it is a partition for Windows recovery files in the event of OS corruption, so I don't want to remove it. Plus it also appears to be a major pain to remove anyways) /dev/sda2 (NTFS) 116.35 out of 339.06 GB used (boot) This partition is the C:/ drive on my Windows installation. I don't use it on my Ubuntu installation, except it is the boot partition and thus has grub on it. /dev/sda4 (extended) > /dev/sda5 (ext4) 14.49 out of 91.34 GB used > /dev/sda6 (linux-swap) 5.92 GB These are my Ubuntu partitions. /sda5 contains my documents and all of the files I use on Ubuntu, and (as far as I know) the system files for Ubuntu itself (it's the partition I created when prompted by the Live-DVD installer). /sda6 is, of course, the swap partition which I only need for hibernation (6GB of RAM). /dev/sda3 (NTFS) 9.89 out of 14.75 GB used This is an annoying partition that Lenovo created to store some drivers and files that I might need later on. For example, it allows me to use OneKeyRecovery for a quick factory recovery if absolutely necessary, not sure if that'll work on an SSD. It also contains not-so-important files for bloatware installation. In total, my HDD only has about 150GB of files on it so it should fit comfortably on the SSD. The problem is, I want to exactly migrate my files, partitions, OSes, MBR, etc. from my HDD to my SSD and I'm not quite sure how to do this. I've seen CloneZilla referenced before, but I'm not all too experienced and the documentation for it quite frankly seems a bit like a foreign language to me. So, put simply, is there any way I can exactly clone this HDD to an SSD without a massive headache? Also, if it matters, I'll probably be using an external hard drive case (as recommended in online tutorials) to externally attach the SSD to my laptop during the cloning process due to the lack of two hard drive slots in the machine.

  • Learn programming backwards, or "so I failed the FizzBuzz test. Now what?"

    - by moraleida
    A Little Background I'm 28 today, and I've never had any formal training in software development, but I do have two higher education degrees equivalent to a B.A in Public Relations and an Executive MBA focused on Project Management. I've worked on those fields for about 6 years total an then, 2,5 years ago I quit/lost my job and decided to shift directions. After a month thinking things through I decided to start freelancing developing small websites in WordPress. I self-learned my way into it and today I can say I run a humble but successful career developing themes and plugins from scratch for my clients - mostly agencies outsourcing some of their dev work for medium/large websites. But sometimes I just feel that not having studied enough math, or not having a formal understanding of things really holds me behind when I have to compete or work with more experienced developers. I'm constantly looking for ways to learn more but I seem to lack the basics. Unfortunately, spending 4 more years in Computer Science is not an option right now, so I'm trying to learn all I can from books and online resources. This method is never going to have NASA employ me but I really don't care right now. My goal is to first pass the bar and to be able to call myself a real programmer. I'm currently spending my spare time studying Java For Programmers (to get a hold on a language everyone says is difficult/demanding), reading excerpts of Code Complete (to get hold of best practices) and also Code: The Hidden Language of Computer Hardware and Software (to grasp the inner workings of computers). TL;DR So, my current situation is this: I'm basically capable of writing any complete system in PHP (with the help of Google and a few books), integrating Ajax, SQL and whatnot, and maybe a little slower than an experienced dev would expect due to all the research involved. But I was stranded yesterday trying to figure out (not Google) a solution for the FizzBuzz test because I didn't have the if($n1 % $n2 == 0) method modulus operator memorized. What would you suggest as a good way to solve this dilemma? What subjects/books should I study that would get me solving problems faster and maybe more "in a programmers way"? EDIT - Seems that there was some confusion about what did I not know to solve FizzBuzz. Maybe I didn't express myself right: I knew the steps needed to solve the problem. What I didn't memorize was the modulus operator. The problem was in transposing basic math to the program, not in knowing basic math. I took the test for fun, after reading about it on Coding Horror. I just decided it was a good base-comparison line between me and formally-trained devs. I just used this as an example of how not having dealt with math in a computer environment before makes me lose time looking up basic things like modulus operators to be able to solve simple problems.

  • Agile Documentation

    - by Nick Harrison
    We all know that one of the premises of the agile manifesto is to value Working Software over Comprehensive Documentation. This is a wonderful idea and it takes a tremendous burden off of project implementations. I have seen as many projects fail because of the maintenance weight of the project documentations as I have for any reason. But this goal as important as it is may not always be practical. Sometimes the client will simply insist on tedious documentation despite the arguments against it. This may be to calm a nervous client. This may be to satisfy an audit / compliance requirement. This may be a non-too subtle attempt at sabotaging the project. Ok, it is probably not an all out attempt to sabotage the project, but it will probably feel that way. So what can we do to keep to the spirit of the Agile Manifesto but still meet the needs of the client wanting the documentation? This is a good question that I have been puzzling over lately! I hope to explore some possible answers more fully here. A common theme that my solutions are likely to follow is the same theme that I often follow with simplifying complex business logic. Make it table driven! My thought is that the sought after documentation could be a report or reports out of a metadata repository. Reports are much easier to maintain than hand written documentation. Here are a few additional advantages that we can explore over time: Reports will take advantage of the fact that different people have different needs and different format requirements Reports and the supporting metadata are more easily validated and the validation can be automated. If the application itself uses this metadata than there never has to be a question as to whether or not the metadata is up to date. It is up to date or the application would not work. In many cases we should be able to automatically gather most of the Meta data that we need using reflection, system tables, etc. I think that this will lower the total cost of ownership for the documentation and may provide something useful beyond having a pretty document to look at.  What are your thoughts?

  • What is this algorithm for converting strings into numbers called?

    - by CodexArcanum
    I've been doing some work in Parsec recently, and for my toy language I wanted multi-based fractional numbers to be expressible. After digging around in Parsec's source a bit, I found their implementation of a floating-point number parser, and copied it to make the needed modifications. So I understand what this code does, and vaguely why (I haven't worked out the math fully yet, but I think I get the gist). But where did it come from? This seems like a pretty clever way to turn strings into floats and ints, is there a name for this algorithm? Or is it just something basic that's a hole in my knowledge? Did the folks behind Parsec devise it? Here's the code, first for integers: number' :: Integer -> Parser Integer number' base = do { digits <- many1 ( oneOf ( sigilRange base )) ; let n = foldl (\x d -> base * x + toInteger (convertDigit base d)) 0 digits ; seq n (return n) } So the basic idea here is that digits contains the string representing the whole number part, ie "192". The foldl converts each digit individually into a number, then adds that to the running total multiplied by the base, which means that by the end each digit has been multiplied by the correct factor (in aggregate) to position it. The fractional part is even more interesting: fraction' :: Integer -> Parser Double fraction' base = do { digits <- many1 ( oneOf ( sigilRange base )) ; let base' = fromIntegral base ; let f = foldr (\d x -> (x + fromIntegral (convertDigit base d))/base') 0.0 digits ; seq f (return f) Same general idea, but now a foldr and using repeated division. I don't quite understand why you add first and then divide for the fraction, but multiply first then add for the whole. I know it works, just haven't sorted out why. Anyway, I feel dumb not working it out myself, it's very simple and clever looking at it. Is there a name for this algorithm? Maybe the imperative version using a loop would be more familiar?

  • Microsoft Azure News: Capturing VM Images

    - by Herve Roggero
    Originally posted on: http://geekswithblogs.net/hroggero/archive/2014/05/21/microsoft-azure-news-capturing-vm-images.aspxIf you have a Virtual Machine (VM) in Microsoft Azure that has a specific configuration, it used to be difficult to clone that VM. You had to sysprep the VM, and clone the data disks. This was slow, prone to errors, and stopped you from being productive. No more! A new option, called Capture, allows you to easily select a VM, running or not. The capture will copy the OS disk and data disks and create a new image out of it automatically for you. This means you can now easily clone an entire VM without affecting productivity.  To capture a VM, simply browse to your Virtual Machines in the Microsoft Azure management website, select the VM you want to clone, and click on the Capture button at the bottom. A window will come up asking to name your image. It took less than 1 minute for me to build a clone of my server. And because it is stored as an image, I can easily create a new VM with it. So that’s what I did… And that took about 5 minutes total.  That’s amazing…  To create a new VM from your image, click on the NEW icon (bottom left), select Compute/Virtual Machine/From Gallery, and select My Images from the left menu when selecting an Image. You will find your newly created image. Because this is a clone, you will not be prompted for a new login; the user id/password is the same.

  • Is it okay to have people with multiple roles in a Scrum team?

    - by Wayne M
    I'm evaluating some Agile-style methodologies for possible introduction to my team. With Scrum, is it allowable to have the same person perform multiple roles? We have a small team of four developers and a web designer; we don't really have a lead (I fulfill this role), QA testers or business analysts, and all of our development tasks come from the CIO. Automated testing is seen as a total waste of time, and everything focuses on speed and not quality. What will happen is the CIO will come up with a development task (whether a feature or a bug) and give it to a developer (not to the whole team, to an individual, often in private or out of the blue) who is then expected to get it completed. The CIO doesn't gather requirements beyond the initial idea (and this has bitten us before as we'll implement something only to find out that none of the end users can use the feature, because they weren't consulted or even informed about it before we developed it, and in a panic we'll be told to revert the change) but requires say in/approval of everything that we do. First things first, is a Scrum style something to consider to introduce some standards and practices? From reading, Scrum seems to rely on a bit more trust and communication and focuses more on project management than on development, which is something we are completely devoid of as we don't have any semblance of project management at present. Second, if it can work is it unreasonable for someone, let's say myself, to act as both ScrumMaster and a developer? Or for a developer to also be the Product Owner (although chances are this will be the CIO, who isn't a developer)? I realize the Scrum Master and the Product Owner should be different people but at the same time I don't think we have anyone who has the qualities of a Product Owner (chances are it would turn into a "I need all these stories, I don't care how but get it done" type of deal and/or any freeze would be unfrozen on a whim). It seems to me that I might need to pick and choose pieces of Scrum/XP/Lean to compensate for how things are done currently, as it's highly unlikely that the mentality can be changed; for instance Pair Programming would never fly (seen as a waste, you get half the tasks done if you need two people for everything), TDD would be a hard sell, but short cycles would be welcomed.

  • Please Help Me Install Firestorm?

    - by Elle Caszatt
    I have been trying for hours just to install one program. In this time, I've tried my best to follow directions and not screw everything up but I have. I'm new to Linux. I tried to install Firestorm and this is what happened: parent@ubuntu:~$ sudo '/home/parent/Downloads/Phoenix_Firestorm-Release_i686_4.2.1.29803/install.sh' [sudo] password for parent: Enter the desired installation directory [/opt/firestorm-install]: /home/parent/downloads - Installing to /home/parent/downloads /home/parent/Downloads/Phoenix_Firestorm-Release_i686_4.2.1.29803/install.sh: line 80: /home/parent/downloads/etc/refresh_desktop_app_entry.sh: Permission denied parent@ubuntu:~$ sudo opt/firestorm-install sudo: opt/firestorm-install: command not found parent@ubuntu:~$ ./etc/refresh_desktop_app_entry.sh bash: ./etc/refresh_desktop_app_entry.sh: No such file or directory parent@ubuntu:~$ sudo '/home/parent/Downloads/Phoenix_Firestorm-Release_i686_4.2.1.29803/install.sh' Enter the desired installation directory [/opt/firestorm-install]: /home/parent - Backing up previous installation to /home/parent.backup-2012-08-27 - Installing to /home/parent cp: cannot stat `/home/parent/Downloads/Phoenix_Firestorm-Release_i686_4.2.1.29803/*': No such file or directory Failed parent@ubuntu:~$ Now whenever I go into my files it says it can't find anything. Like Cannot find home/parent/Downloads. Now, I KNOW there are downloads. I don't know why it's doing this all of a sudden. I'm so frustrated that I'm ready to just go back to Windows. I've already had to uninstall/reinstall Ubuntu once today. It's looking like I"m going to have to do it again. How can I fix my file problem that I'm now having and can someone please, please tell me how to install Firestorm? I mean they don't even have their repository listed. It's ridiculous to have to go through this over a program. Spotify wasn't hard at all to install so why is this? Someone please help, and I'm sorry if I sound like a total idiot. I'm pretty tech savvy but I'm honestly pretty upset after struggling with this for hours. Edit Okay, I see the problem with the directory files (showing the error I mentioned above when I try to click on them). I can only access my downloads, desktop, ect, through the backup that was created when I tried to install Firestorm. It's like that's the real home now. How can I get it back to the way it was? Edit Ubuntu has stopped working for me on reboot now. It doesn't go past the login screen. This is exactly what happened when I had to uninstall it before after trying to install Firestorm. Maybe I'm giving up too easily but I think I'm just going to go back to Windows. If this is what's going to happen every time I innocently try to install a program then it's just not worth it. I installed it specifically to run Firestorm because Windows sucks up a lot of CPU and causes lag. I still appreciate any input but this is just too much hassle for something that shouldn't be hard.

  • 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.

  • Will you share your SQL Server configuration?

    - by Bill Graziano
    I regularly visit client sites and review their SQL Server configurations.  I come across all kinds of strange settings.  I’ve been thinking about a way to aggregate people’s configurations and see what’s common and what’s unique.  I used to do that with polls on SQLTeam.com.  I think we can find out more interesting things if we look at combinations of settings in relation to size and volume. I’ve been working on an application for another project that is similar.  It will be fairly easy to use that code for this.  I can have something up and running in a few days – if people are interested in it.  I admit that I often come up with ideas that just don’t make sense.  This may be one of them.  One of your biggest concerns has be how secure your data is.  My solution is not to store anything identifying.  The instance name and database names can both be “anonymized” and I don’t store the machine name or IP address or anything to do with logins. Some of the questions I’m curious about are: At what size database does the Enterprise Edition become prevalent? Given the total size of the databases how much RAM is common? How many people have multiple data files?  At what size does that become prevalent? How common is database mirroring?  Replication?  Log shipping? How common is full recovery mode?  At what data size does it become prevalent? I think those are all questions that are easy to answer -- with the right data.  The big question is whether or not people will share their SQL Server configurations.  I understand that organizations in regulated or high security environments can’t participate.  But I think that leaves many, many people that can.  Are you willing to share your configuration and learn about others?  I have a simple sign up form here.  It’s actually a mailing list signup that also captures your edition, number of servers and largest database.  The list will only be used for this project.  Is your SQL Server is configured correctly?  Do you wonder what the next step is as your data grows?  Take a second and sign up.

  • Access denied error while mounting a shared folder?

    - by SSH
    I am a linux newbie and I have a very basic question. I have three machines - machineA 10.108.24.132 machineB 10.108.24.133 machineC 10.108.24.134 and all those machines have Ubuntu 12.04 installed in it and I have root access to all those three machines. Now I am supposed to do below things in my above machines - Create mount point /opt/exhibitor/conf Mount the directory in all servers. sudo mount <NFS-SERVER>:/opt/exhibitor/conf /opt/exhibitor/conf/ I have already created /opt/exhibitor/conf directory in all those three machines as mentioned above. Now I am trying to create a Mount Point on all those three machines. So I followed the below process - Install NFS support files and NFS kernel server in all the above three machines $ sudo apt-get install nfs-common nfs-kernel-server Create the shared directory in all the above three machines $ mkdir /opt/exhibitor/conf/ Edited the /etc/exports and added the entry like this in all the above three machines - # /etc/exports: the access control list for filesystems which may be exported # to NFS clients. See exports(5). # # Example for NFSv2 and NFSv3: # /srv/homes hostname1(rw,sync,no_subtree_check) hostname2(ro,sync,no_subtree_check) # # Example for NFSv4: # /srv/nfs4 gss/krb5i(rw,sync,fsid=0,crossmnt,no_subtree_check) # /srv/nfs4/homes gss/krb5i(rw,sync,no_subtree_check) # /opt/exhibitor/conf/ 10.108.24.*(rw) Run exportfs in all the above three machines root@machineA:/# exportfs -rv exportfs: /etc/exports [1]: Neither 'subtree_check' or 'no_subtree_check' specified for export "10.108.24.*:/opt/exhibitor/conf/". Assuming default behaviour ('no_subtree_check'). NOTE: this default has changed since nfs-utils version 1.0.x exporting 10.108.24.*:/opt/exhibitor/conf Now I did showmount on machineA root@machineA:/# showmount -e 10.108.24.132 Export list for 10.108.24.132: /opt/exhibitor/conf 10.108.24.* And also I have started the NFS server like this in all the above three machines - sudo /etc/init.d/nfs-kernel-server start And now when I did this, I am getting an error - root@machineA:/# sudo mount -t nfs 10.108.24.132:/opt/exhibitor/conf /opt/exhibitor/conf/ mount.nfs: access denied by server while mounting 10.108.24.132:/opt/exhibitor/conf I have also tried doing the same thing from machineB and machineC as well and still I get the same error- root@machineB:/# sudo mount -t nfs 10.108.24.132:/opt/exhibitor/conf /opt/exhibitor/conf/ root@machineC:/# sudo mount -t nfs 10.108.24.132:/opt/exhibitor/conf /opt/exhibitor/conf/ Did my /etc/exports file looks good? As I have the same content in all the three machines. And also are there any logs related to NFS which I can see to find any clues? Any idea what wrong I am doing here? UPDATE:- So my etc/exports files would be like this in all the three machines - # /etc/exports: the access control list for filesystems which may be exported # to NFS clients. See exports(5). # # Example for NFSv2 and NFSv3: # /srv/homes hostname1(rw,sync,no_subtree_check) hostname2(ro,sync,no_subtree_check) # # Example for NFSv4: # /srv/nfs4 gss/krb5i(rw,sync,fsid=0,crossmnt,no_subtree_check) # /srv/nfs4/homes gss/krb5i(rw,sync,no_subtree_check) # /opt/exhibitor/conf/ 10.108.24.132(rw) /opt/exhibitor/conf/ 10.108.24.133(rw) /opt/exhibitor/conf/ 10.108.24.134(rw) Just a quick check - The IP Address that I am taking for each machine as mentioned above is like this - root@machineB:/# ifconfig eth0 Link encap:Ethernet HWaddr 00:50:56:ad:5b:a7 inet addr:10.108.24.133 Bcast:10.108.27.255 Mask:255.255.252.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:5696812 errors:0 dropped:12462 overruns:0 frame:0 TX packets:5083427 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:7904369145 (7.9 GB) TX bytes:601844910 (601.8 MB) lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:187144 errors:0 dropped:0 overruns:0 frame:0 TX packets:187144 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:24012302 (24.0 MB) TX bytes:24012302 (24.0 MB) Here the IP Address that I am taking for machineB is 10.108.24.133.

  • Accessing SQL Server data from iOS apps

    - by RobertChipperfield
    Almost all mobile apps need access to external data to be valuable. With a huge amount of existing business data residing in Microsoft SQL Server databases, and an ever-increasing drive to make more and more available to mobile users, how do you marry the rather separate worlds of Microsoft's SQL Server and Apple's iOS devices? The classic answer: write a web service layer Look at any of the questions on this topic asked in Internet discussion forums, and you'll inevitably see the answer, "just write a web service and use that!". But what does this process gain? For a well-designed database with a solid security model, and business logic in the database, writing a custom web service on top of this just to access some of the data from a different platform seems inefficient and unnecessary. Desktop applications interact with the SQL Server directly - why should mobile apps be any different? The better answer: the iSql SDK Working along the lines of "if you do something more than once, make it shared," we set about coming up with a better solution for the general case. And so the iSql SDK was born: sitting between SQL Server and your iOS apps, it provides the simple API you're used to if you've been developing desktop apps using the Microsoft SQL Native Client. It turns out a web service remained a sensible idea: HTTP is much more suited to the Big Bad Internet than SQL Server's native TDS protocol, removing the need for complex configuration, firewall configuration, and the like. However, rather than writing a web service for every app that needs data access, we made the web service generic, serving only as a proxy between the SQL Server and a client library integrated into the iPhone or iPad app. This client library handles all the network communication, and provides a clean API. OSQL in 25 lines of code As an example of how to use the API, I put together a very simple app that allowed the user to enter one or more SQL statements, and displayed the results in a rather primitively formatted text field. The total amount of Objective-C code responsible for doing the work? About 25 lines. You can see this in action in the demo video. Beta out now - your chance to give us your suggestions! We've released the iSql SDK as a beta on the MobileFoo website: you're welcome to download a copy, have a play in your own apps, and let us know what we've missed using the Feedback button on the site. Software development should be fun and rewarding: no-one wants to spend their time writing boiler-plate code over and over again, so stop writing the same web service code, and start doing exciting things in the new world of mobile data!

  • I cannot remove/install software some dependency issue?

    - by Ryuzaki
    I'm having difficulty trying to install/uninstall applications in Ubuntu 12.04 LTS. I have this warning error that appears on my desktop in the form of a red icon with a line through it and it states: An error occurred, please run Package Manager from the right-click menu or apt-get in a terminal to see what is wrong. The error message was: 'Error: BrokenCount 0' — This usually means that your installed packages have unmet dependencies. I tried to repair automatically through ubuntu software center and I kept getting errors or it just didn't seem to work. Afterwards, I opened terminal and used sudo apt-get check command to see what the problem was and the results yielded: Reading package lists... Done Building dependency tree Reading state information... Done You might want to run 'apt-get -f install' to correct these. The following packages have unmet dependencies: libjack-jackd2-0 : Breaks: libjack-jackd2-0:i386 (!= 1.9.8~dfsg.1-1ubuntu1) but 1.9.8~dfsg.2-1precise1 is installed libjack-jackd2-0:i386 : Breaks: libjack-jackd2-0 (!= 1.9.8~dfsg.2-1precise1) but 1.9.8~dfsg.1-1ubuntu1 is installed E: Unmet dependencies. Try using -f. After I ran sudo apt-get -f install (in an attempt to fix the issue at hand), I encountered the following errors/code: okudaira@haru-kano:~$ sudo apt-get -f install Reading package lists...

I'm fairly new to the ubuntu experience so I'm not very well-versed with the terminology and the entire in's and out's. Can someone tell me what's wrong with my system? I can no longer install/remove any programs at all.
