  • English major new to programming. What language should I learn first? [closed]

    - by PJKaka
    After working extensively an internet startup in a marketing positions, I've decided to wade into the entrepreneurship pool with a startup of my own. The only problem: I don't have any particular technical skills to speak of. Although I can find a technical co-founder, I'd rather not be the stereotypical 'business guy' drumming his fingers on the desk and asking 'how much longer?' as my technical co-founder codes away. I would like to understand code and what's happening in the backend, even if I don't end up being anything more than a 'passable' programmer. With this in mind, which language should I try to learn first? For the record, I'm quite proficient with HTML, CSS, and a bit of JavaScript. I have some familiarity with PHP because I've toyed around with WordPress a lot, but my knowledge is limited at best. My math skills are quite strong. I took some advanced calculus courses in college since I've always enjoyed the subject. While my goals are to learn web development, I wouldn't mind learning some hardcore object oriented programming skills in C or Java as well.

  • 11.10 system crashes for no apparent reason [closed]

    - by varanoid
    I'm relatively new to Linux, and while I know a fair amount about computers and programming, it certainly isn't my specialty. I have a dual boot with Windows 7, and it has been working very well for me until recently. Just randomly the computer will freeze. The last time I was smart enough to keep the System Monitor open when it happened, and it looks like at the time of freezing "bash" and a bunch of other processes that I don't recognize seem to have flooded the memory. So it looks like my memory is getting overloaded and this is what is crashing the system, but I honestly have no idea what could be doing it. Generally I have a bunch of programs running, but they don't take much RAM or CPU: Transmission, Libre Office Writer, Firefox, Empathy, and Banshee. Sometimes I also have Text Editor and Terminal open, but it crashes regardless. When it crashes, it seems that all of the programs are working fine but things like windows, the taskbar, and operations like Alt+Tab just stop working properly or at all. Sometimes the mouse and keyboard freeze and I have to power off manually. Other than that I don't know what the problem is. The only irregularity I've experienced is that I can't download "Debian package management system" even though other updates download fine.

  • Compensation advice on overseas contract with former employer [closed]

    - by user64248
    I work as a full time developer in the US. My previous employer from 3 years ago has sold a large startup project in Russia for next month, however their three and only senior developers have recently resigned. I still have somewhat intricate knowledge of the software to be installed since I was the original author, so my former employer, in somewhat of a panic, has asked if I can take two weeks vacation from my current job to fly to Russia and lead the startup. Logistically, I can do this and my current employer agreed without issue. Said former employer is very small and hasn't hired contractors before, and I haven't contracted either. The company simply asked my what my salary requirements are. I had, and still have, a great professional relationship with the owners. I feel like I'm doing this as a favor in a way. Payment is guaranteed, but I have no idea what I should bill for overseas work. If it matters, I was paid around 110k at the former employer. Just looking for some advice. There are many contracting salary threads here, but I feel that the overseas work throws a twist in things. Thank you!

  • Single CAS web application in a cluster

    - by Dolf Dijkstra
    Recently a customer wanted to set up a cluster of CAS nodes to be used together with WebCenter Sites. In the process of setting this up they realized that they needed to create a web application per managed server. They did not want to have this management burden but would like to have one web application deployed to multiple nodes. The reason that there is a need for a unique application per node is that the web-application contains information that needs to be unique per node, the postfix for the ticket id.  My customer would like to externalize the node specific configuration to either a specific classpath per managed server or to system properties set at startup.It turns out that the postfix for ticket ids is managed through a property host.name and that this property can be externalized.The host.name property is used in: /webapps/cas/WEB-INF/spring-configuration/uniqueIdGenerators.xmlIt is set in /webapps/cas/WEB-INF/spring-configuration/propertyFileConfigurer.xmlin a PropertyPlaceholderConfigurer.The documentation for PropertyPlaceholderConfigurer:http://static.springsource.org/spring/docs/2.0.x/api/org/springframework/beans/factory/config/PropertyPlaceholderConfigurer.htmlThis indicates that the properties defined through the PropertyPlaceHolderConfigurer can be externalized.To enable this externalization you would need to change host.properties so it is generic for all the managed servers and thus can be reused for all the managed servers: host.name=${cluster.node.id}Next step is to change the startup scripts for the managed servers and add a system property for -Dcluster.node.id=<something unique and stable>.Viola, the postfix is externalized and the web application can be shared amongst the cluster nodes.

  • How can I restore my Acer Aspire one GNU version 1.98 to factory settings?

    - by user100380
    Requires keyring and authentication to install and unistall programs or update anything. I just want to restart from scratch so i can clean it up anyways. Can anyone help? Also, on start up a list on a black screen will come up saying Ubuntu with linux version 26.32-40 generic or recovery version and at the bottom of different versions has one Window 7 loader option. When I get into recovery menu to try and restore to factory settings my netbook has no restore option. I've tried pressing alt-f10 and holding alt and repeatedly tap f10 but nothing seems to work, and my acer asks for a password login to even load windows 7 which I don't have. Any ideas? I've looked a lot on the internet for help but I'm getting to my last resort, to get of this thing for once and for all. I want to be able to personalize and add programs as I please, this is all bs to go through to unistall one freaking game or get rid of ubuntu gnome keyring!! Please help!! Thank you. :)

  • Is there a better strategy than relying on the compiler to catch errors?

    - by koan
    I've been programming in C and C++ for some time, although I would say I'm far from being an expert. For some time, I've been using various strategies to develop my code such as unit tests, test driven design, code reviews and so on. When I wrote my first programs in BASIC, I typed in long blocks before finding they would not run and they were a nightmare to debug. So I learned to write a small bit and then test it. These days, I often find myself repeatedly writing a small bit of code then using the compiler to find all the mistakes. That's OK if it picks up a typo but when you start adjusting the parameters types etc just to make it compile you can screw up the design. It also seems that the compiler is creeping into the design process when it should only be used for checking syntax. There's a danger here of over reliance on the compiler to make my programs better. Are there better strategies than this? I vaguely remember some time ago an article on a company developing a type of C compiler where an extra header file also specified the prototypes. The idea was that inconsistencies in the API definition would be easier to catch if you had to define it twice in different ways.

  • Make middle-click close window(s) on unity launcher

    - by humanityANDpeace
    I am looking for a way to achieve this on my 12.04 ubuntu system: Clicking with the middle mouse button on one of the unity launcher icons will close the related windows/programs. At present a middle-button-click causes (when possible) another instance of the same programme to start. There is nothing wrong with that, only I use this less often than I need a quick way to close some programs. The current way is a lengthy 2-click way. Right-click on the icon Select "quit" in the unity-setting in the ccsm (compiz config settings manager) some few things can be changed in the ubuntu unity plugin already. there are other reporst about settings being done in dconf and gconf. What chances are there to tweak the behavior as described above? In Firefox I am used to close tabs by "middle-clicking" on the tabs. In GLX/Cairo-dock I also associate "middle-click" with the close the program. When using ubuntu unity launcher I keep on mistakingly opening new windows, when indeed I wanna close the respective window(s). :(

  • What kinds of languages would be most useful for this kind of webapp?

    - by Caedar
    I've had some experience with programming in the past (2-3 years of C++ self-teaching), so I'm no stranger to the programming process, but there are so many languages out there that I'm lost when thinking about this project idea that's been floating around my head: I would like to create a webapp that would be used for helping somebody figure out what kinds of productivity tools would suit them. The first part of the app would basically be a survey with a variety of questions that would help weed out tools that wouldn't be useful for them. (Slider bar between minimalist and maximizer, slider bar between all free apps and no cost limit, checkboxes on what platforms are required, etc.) While the person is filling out the survey, they will see a web of applications, webapps, and other tools forming on the screen with links showing the relationships the programs have with eachother (syncing supported, good combinations of apps, etc.), along with a list of applications below sorted by general use (notetaking, document organization, storage, etc.) I would imagine that each program entered into the database that will be accessed would have a certain set of characteristics, ie. price, user friendliness, platforms supported, general uses, etc. and the survey would be designed to correlate to those elements and remove programs that don't match the criteria set. The difficult part of this entire process would be getting the web of applications to arrange itself and render properly. Now that I've finished mind-dumping, onto my question: What kinds/combinations of programming languages would you imagine being useful for this kind of project, and why? I learn best by setting up a project for myself like this one and tinkering with the languages, so I don't mind if the end product is out of reach from my current skill level. I'd just like some guidance so I don't fumble in the dark for too long.

  • Create a Persistent Bootable Ubuntu USB Flash Drive

    - by Trevor Bekolay
    Don’t feel like reinstalling an antivirus program every time you boot up your Ubuntu flash drive? We’ll show you how to create a bootable Ubuntu flash drive that will remember your settings, installed programs, and more! Previously, we showed you how to create a bootable Ubuntu flash drive that would reset to its initial state every time you booted it up. This is great if you’re worried about messing something up, and want to start fresh every time you start tinkering with Ubuntu. However, if you’re using the Ubuntu flash drive to diagnose and solve problems with your PC, you might find that a lot of problems require guess-and-test cycles. It would be great if the settings you change in Ubuntu and the programs you install stay installed the next time you boot it up. Fortunately, Universal USB Installer, a great little program from Pen Drive Linux, can do just that! Note: You will need a USB drive at least 2 GB large. Make sure you back up any files on the flash drive because this process will format the drive, removing any files currently on it. Once Ubuntu has been installed on the flash drive, you can move those files back if there is enough space. Put Ubuntu on your flash drive Universal-USB-Installer.exe does not need to be installed, so just double click on it to run it wherever you downloaded it. Click Yes if you get a UAC prompt, and you will be greeted with this window. Click I Agree. In the drop-down box on the next screen, select Ubuntu 9.10 Desktop i386. Don’t worry if you normally use 64-bit operating systems – the 32-bit version of Ubuntu 9.10 will still work fine. Some useful tools do not have 64-bit versions, so unless you’re planning on switching to Ubuntu permanently, the 32-bit version will work best. If you don’t have a copy of the Ubuntu 9.10 CD downloaded, then click on the checkbox to Download the ISO. You’ll be prompted to launch a web browser; click Yes. The download should start immediately. When it’s finished, return the the Universal USB Installer and click on Browse to navigate to the ISO file you just downloaded. Click OK and the text field will be populated with the path to the ISO file. Select the drive letter that corresponds to the flash drive that you would like to use from the dropdown box. If you’ve backed up the files on this drive, we recommend checking the box to format the drive. Finally, you have to choose how much space you would like to set aside for the settings and programs that will be stored on the flash drive. Considering that Ubuntu itself only takes up around 700 MB, 1 GB should be plenty, but we’re choosing 2 GB in this example because we have lots of space on this USB drive. Click on the Create button and then make yourself a sandwich – it will take some time to install no matter how fast your PC is. Eventually it will finish. Click Close. Now you have a flash drive that will boot into a fully capable Ubuntu installation, and any changes you make will persist the next time you boot it up! Boot into Ubuntu If you’re not sure how to set your computer to boot using the USB drive, then check out the How to Boot Into Ubuntu section of our previous article on creating bootable USB drives, or refer to your motherboard’s manual. Once your computer is set to boot using the USB drive, you’ll be greeted with splash screen with some options. Press Enter to boot into Ubuntu. The first time you do this, it may take some time to boot up. Fortunately, we’ve found that the process speeds up on subsequent boots. You’ll be greeted with the Ubuntu desktop. Now, if you change settings like the desktop resolution, or install a program, those changes will be permanently stored on the USB drive! We installed avast! Antivirus, and on the next boot, found that it was still in the Accessories menu where we left it. Conclusion We think that a bootable Ubuntu USB flash drive is a great tool to have around in case your PC has problems booting otherwise. By having the changes you make persist, you can customize your Ubuntu installation to be the ultimate computer repair toolkit!

  • WebLogic Server Performance and Tuning: Part I - Tuning JVM

    - by Gokhan Gungor
    Each WebLogic Server instance runs in its own dedicated Java Virtual Machine (JVM) which is their runtime environment. Every Admin Server in any domain executes within a JVM. The same also applies for Managed Servers. WebLogic Server can be used for a wide variety of applications and services which uses the same runtime environment and resources. Oracle WebLogic ships with 2 different JVM, HotSpot and JRocket but you can choose which JVM you want to use. JVM is designed to optimize itself however it also provides some startup options to make small changes. There are default values for its memory and garbage collection. In real world, you will not want to stick with the default values provided by the JVM rather want to customize these values based on your applications which can produce large gains in performance by making small changes with the JVM parameters. We can tell the garbage collector how to delete garbage and we can also tell JVM how much space to allocate for each generation (of java Objects) or for heap. Remember during the garbage collection no other process is executed within the JVM or runtime, which is called STOP THE WORLD which can affect the overall throughput. Each JVM has its own memory segment called Heap Memory which is the storage for java Objects. These objects can be grouped based on their age like young generation (recently created objects) or old generation (surviving objects that have lived to some extent), etc. A java object is considered garbage when it can no longer be reached from anywhere in the running program. Each generation has its own memory segment within the heap. When this segment gets full, garbage collector deletes all the objects that are marked as garbage to create space. When the old generation space gets full, the JVM performs a major collection to remove the unused objects and reclaim their space. A major garbage collect takes a significant amount of time and can affect system performance. When we create a managed server either on the same machine or on remote machine it gets its initial startup parameters from $DOMAIN_HOME/bin/setDomainEnv.sh/cmd file. By default two parameters are set:     Xms: The initial heapsize     Xmx: The max heapsize Try to set equal initial and max heapsize. The startup time can be a little longer but for long running applications it will provide a better performance. When we set -Xms512m -Xmx1024m, the physical heap size will be 512m. This means that there are pages of memory (in the state of the 512m) that the JVM does not explicitly control. It will be controlled by OS which could be reserve for the other tasks. In this case, it is an advantage if the JVM claims the entire memory at once and try not to spend time to extend when more memory is needed. Also you can use -XX:MaxPermSize (Maximum size of the permanent generation) option for Sun JVM. You should adjust the size accordingly if your application dynamically load and unload a lot of classes in order to optimize the performance. You can set the JVM options/heap size from the following places:     Through the Admin console, in the Server start tab     In the startManagedWeblogic script for the managed servers     $DOMAIN_HOME/bin/startManagedWebLogic.sh/cmd     JAVA_OPTIONS="-Xms1024m -Xmx1024m" ${JAVA_OPTIONS}     In the setDomainEnv script for the managed servers and admin server (domain wide)     USER_MEM_ARGS="-Xms1024m -Xmx1024m" When there is free memory available in the heap but it is too fragmented and not contiguously located to store the object or when there is actually insufficient memory we can get java.lang.OutOfMemoryError. We should create Thread Dump and analyze if that is possible in case of such error. The second option we can use to produce higher throughput is to garbage collection. We can roughly divide GC algorithms into 2 categories: parallel and concurrent. Parallel GC stops the execution of all the application and performs the full GC, this generally provides better throughput but also high latency using all the CPU resources during GC. Concurrent GC on the other hand, produces low latency but also low throughput since it performs GC while application executes. The JRockit JVM provides some useful command-line parameters that to control of its GC scheme like -XgcPrio command-line parameter which takes the following options; XgcPrio:pausetime (To minimize latency, parallel GC) XgcPrio:throughput (To minimize throughput, concurrent GC ) XgcPrio:deterministic (To guarantee maximum pause time, for real time systems) Sun JVM has similar parameters (like  -XX:UseParallelGC or -XX:+UseConcMarkSweepGC) to control its GC scheme. We can add -verbosegc -XX:+PrintGCDetails to monitor indications of a problem with garbage collection. Try configuring JVM’s of all managed servers to execute in -server mode to ensure that it is optimized for a server-side production environment.

  • &ldquo;My life at Oracle&rdquo;

    - by cristian.condurache(at)oracle.com
    Hello everybody! My name is Eva and I currently work in Oracle Italy as Sales Programs Manager for the Technology Sales organization. Since 2009, I also proudly represent the Oracle Education Foundation within my country as the Ambassador for Italy. My career path in this amazing company began 5 years ago as a fresh graduate: after various years studying abroad, in Germany and Ireland mainly, I was looking for a valuable and concrete opportunity which could fulfill my energetic spirit. I wanted to develop myself inside a stimulating and “fast” business environment.. and here came Oracle and I really couldn’t ask for anything better!  THE PARTNER EXPERIENCE The first department I had the chance to work into was the Alliances and Channels organization, where I had the opportunity to join a brilliant team of great and visionary guys. I began having the responsibility to analyze and rationalize the portfolio of Oracle business partners and to identify potential cross-area solutions, which had to be highlighted both on the local market and internationally: this ended up with the implementation of the “Partner Community” model, a business environment of selected Oracle partners, specialized on the different technology focus areas. This new concept was then recognized as an EMEA Best Practice and replicated internationally. Having the opportunity to strengthen day after day strategic relationships with several business partners and study the market positioning of their technology solutions, I was given the role to develop the “Oracle Partner Network Innovation Award” in Italy: the EMEA competition encouraging and rewarding proven and successful technology innovations, creating high value for our common customers and generating new business potential. Several Italian partner solutions won different prizes and I decided that it was worth collecting all those valuable projects, winners and short-listed, inside two specific books in order also to provide them an international market visibility: OPN Innovation Award Booklet 2007 and OPN Innovation Award Booklet 2008 Inside the Alliances and Channels department I really had the opportunity to do    amazing things, like for example working side-by-side with one of the most exceptional teams in Oracle I have ever worked with: the EMEA Recruitment Team. Together, in fact, we conceived a brand new business initiative for our partners, called “Oracle Campus Joint Program”. This program was awarded as an EMEA Best Practice and acknowledged by both Italian public institutions and press media. Italy   is currently running its 5th edition.   Briefly, the “Oracle Campus Joint Program” aims at facing the growing issue of lack of  technology competences and skills on the market. By identifying a specific technology area and developing an intensive 4-6 week Oracle University training course and by collaborating with important academic institutes, international “gurus” and professionals, our business partners are able to benefit from a pool of brilliant top talented young consultants and offer them a significant career opportunity. BUSINESS BUT NOT ONLY: THE NO-PROFIT EXPERIENCE OF ORACLE Currently my mission in Oracle is to continue driving the implementation of strategic business development and sales programs for the entire Oracle Technology stack, involving both partners and the end-customers. But as a completely distinguished role from the day-today business, I’m also honored to represent in Italy the charity global organization founded by Oracle - the Oracle Education Foundation - and drive its corporate citizenship and marketing programs. Oracle Education Foundation is an independent charitable organization funded by Oracle and is dedicated to helping students develop 21st century skills through project learning and the use of technology. It provides “ThinkQuest” as a free program to primary and secondary (K12) schools. Just some significant numbers: today 548,000 students/teachers in 47 countries use ThinkQuest and the Oracle Education Foundation partners with 40+ no-profit or government organizations globally. ABOUT MYSELF AND MY INTERESTS About myself…I’m very enthusiastic and positive, trying always to transform difficult issues in challenging opportunities. My day usually begins very early in the morning with running, swimming or when I need to collect some “zen” energies with a yoga session or better with a long walk with my dog. I definitely love animals and generally speaking I’m very keen on environmental issues and try, as much as I can, to carry out a healthy and “planet respectful” lifestyle. My thirst for knowledge pushed me some time ago to begin a new personal challenge: I decided to enroll, dedicating a good part of my free time, for a second university degree: I chose “Neuroeconomics”, an innovative academic path which combines psychology, economics, and neuroscience and studies how people make decisions and the role of the brain when people evaluate these decisions, categorizing risks and rewards and generally interacting with each other. I’ve been very glad to talk about my experience in this article, as working for Oracle is something very stimulating. This company ensures you the opportunity to face new challenges, work with highly talented people and be professionally highlighted also globally. Motivation, good results and innovation is always pursued, recognized and fully supported. Thanks and wish you all an amazing career! If you have any question please contact [email protected].

  • Running Jetty under Windows Azure Using RoleEntryPoint in a Worker Role

    - by Shawn Cicoria
    This post is built upon the work of Mario Kosmiskas and David C. Chou’s prior postings – from here: http://blogs.msdn.com/b/mariok/archive/2011/01/05/deploying-java-applications-in-azure.aspx  http://blogs.msdn.com/b/dachou/archive/2010/03/21/run-java-with-jetty-in-windows-azure.aspx As Mario points out in his post, when you need to have more control over the process that starts, it generally is better left to a RoleEntryPoint capability that as of now, requires the use of a CLR based assembly that is deployed as part of the package to Azure. There were things I liked especially about Mario’s post – specifically, the ability to pull down the JRE and Jetty runtimes at role startup and instantiate the process using the extracted bits.  The way Mario initialized the java process (and Jetty) was to take advantage of a role startup task configured as part of the service definition.  This is a great quick way to kick off processes or tasks prior to your role entry point.  However, if you need access to service configuration values or role events, that’s where RoleEntryPoint comes in.  For this PoC sample I moved the logic for retrieving the bits for the jre and jetty to the worker roles OnStart – in addition to moving the process kickoff to the OnStart method.  The Run method at this point is there to loop and just report the status of the java process. Beyond just making things more parameterized, both Mario’s and David’s articles still form the essence of the approach. The solution that accompanies this post provides all the necessary .NET based Visual Studio project.  In addition, you’ll need: 1. Jetty 7 runtime http://www.eclipse.org/jetty/downloads.php 2. JRE http://www.oracle.com/technetwork/java/javase/downloads/index.html Once you have these the first step is to create archives (zips) of the distributions.  For this PoC, the structure of the archive requires that the root of the archive looks as follows: JRE6.zip jetty---.zip Upload the contents to a storage container (block blob), and for this example I used /archives as the location.  The service configuration has several settings that allow, which is the advantage of using RoleEntryPoint, the ability to provide these things via native configuration support from Azure in a worker role. Storage Explorer You can use development storage for testing this out – the zipped version of the solution is configured for development storage.  When you’re ready to deploy, you update the two settings – 1 for diagnostics and the other for the storage container where the /archives are going to be stored. <?xml version="1.0" encoding="utf-8"?> <ServiceConfiguration serviceName="HostedJetty" osFamily="2" osVersion="*"> <Role name="JettyWorker"> <Instances count="1" /> <ConfigurationSettings> <!--<Setting name="Microsoft.WindowsAzure.Plugins.Diagnostics.ConnectionString" value="DefaultEndpointsProtocol=https;AccountName=<accountName>;AccountKey=<accountKey>" />--> <Setting name="Microsoft.WindowsAzure.Plugins.Diagnostics.ConnectionString" value="UseDevelopmentStorage=true" /> <Setting name="JettyArchive" value="jetty-distribution-7.3.0.v20110203b.zip" /> <Setting name="StartRole" value="true" /> <Setting name="BlobContainer" value="archives" /> <Setting name="JreArchive" value="jre6.zip" /> <!--<Setting name="StorageCredentials" value="DefaultEndpointsProtocol=https;AccountName=<accountName>;AccountKey=<accountKey>"/>--> <Setting name="StorageCredentials" value="UseDevelopmentStorage=true" />   For interacting with Storage you can use several tools – one tool that I like is from the Windows Azure CAT team located here: http://appfabriccat.com/2011/02/exploring-windows-azure-storage-apis-by-building-a-storage-explorer-application/  and shown in the prior picture At runtime, during role initialization and startup, Azure will call into your RoleEntryPoint.  At that time the code will do a dynamic pull of the 2 archives and extract – using the Sharp Zip Lib <link> as Mario had demonstrated in his sample.  The only different here is the use of CLR code vs. PowerShell (which is really CLR, but that’s another discussion). At this point, once the 2 zips are extracted, the Role’s file system looks as follows: Worker Role approot From there, the OnStart method (which also does the download and unzip using a simple StorageHelper class) kicks off the Java path and now you have Java! Task Manager Jetty Sample Page A couple of things I’m working on to enhance this is to extract the jre and jetty bits not to the appRoot but to a resource location defined as part of the service definition. ServiceDefinition.csdef <?xml version="1.0" encoding="utf-8"?> <ServiceDefinition name="HostedJetty" xmlns="http://schemas.microsoft.com/ServiceHosting/2008/10/ServiceDefinition"> <WorkerRole name="JettyWorker"> <Imports> <Import moduleName="Diagnostics" /> <Import moduleName="RemoteAccess" /> <Import moduleName="RemoteForwarder" /> </Imports> <Endpoints> <InputEndpoint name="JettyPort" protocol="tcp" port="80" localPort="8080" /> </Endpoints> <LocalResources> <LocalStorage name="Archives" cleanOnRoleRecycle="false" sizeInMB="100" /> </LocalResources>   As the concept matures a bit, being able to update dynamically the content or jar files as part of a running java solution is something that is possible through continued enhancement of this simple model. The Visual Studio 2010 Solution is located here: HostingJavaSln_NDA.zip

  • How to Sync Any Folder With SkyDrive on Windows 8.1

    - by Chris Hoffman
    Before Windows 8.1, it was possible to sync any folder on your computer with SkyDrive using symbolic links. This method no longer works now that SkyDrive is baked into Windows 8.1, but there are other tricks you can use. Creating a symbolic link or directory junction inside your SkyDrive folder will give you an empty folder in your SkyDrive cloud storage. Confusingly, the files will appear inside the SkyDrive Modern app as if they were being synced, but they aren’t. The Solution With SkyDrive refusing to understand and accept symbolic links in its own folder, the best option is probably to use symbolic links anyway — but in reverse. For example, let’s say you have a program that automatically saves important data to a folder anywhere on your hard drive — whether it’s C:\Users\USER\Documents\, C:\Program\Data, or anywhere else. Rather than trying to trick SkyDrive into understanding a symbolic link, we could instead move the actual folder itself to SkyDrive and then use a symbolic link at the folder’s original location to trick the original program. This may not work for every single program out there. But it will likely work for most programs, which use standard Windows API calls to access folders and save files. We’re just flipping the old solution here — we can’t trick SkyDrive anymore, so let’s try to trick other programs instead. Moving a Folder and Creating a Symbolic Link First, ensure no program is using the external folder. For example, if it’s a program data or settings folder, close the program that’s using the folder. Next, simply move the folder to your SkyDrive folder. Right-click the external folder, select Cut, go to the SkyDrive folder, right-click and select Paste. The folder will now be located in the SkyDrive folder itself, so it will sync normally. Next, open a Command Prompt window as Administrator. Right-click the Start button on the taskbar or press Windows Key + X and select Command Prompt (Administrator) to open it. Run the following command to create a symbolic link at the original location of the folder: mklink /d “C:\Original\Folder\Location” “C:\Users\NAME\SkyDrive\FOLDERNAME\” Enter the correct paths for the exact location of the original folder and the current location of the folder in your SkyDrive. Windows will then create a symbolic link at the folder’s original location. Most programs should hopefully be tricked by this symbolic location, saving their files directly to SkyDrive. You can test this yourself. Put a file into the folder at its original location. It will be saved to SkyDrive and sync normally, appearing in your SkyDrive storage online. One downside here is that you won’t be able to save a file onto SkyDrive without it taking up space on the same hard drive SkyDrive is on. You won’t be able to scatter folders across multiple hard drives and sync them all. However, you could always change the location of the SkyDrive folder on Windows 8.1 and put it on a drive with a larger amount of free space. To do this, right-click the SkyDrive folder in File Explorer, select Properties, and use the options on the Location tab. You could even use Storage Spaces to combine the drives into one larger drive. Automatically Copy the Original Files to SkyDrive Another option would be to run a program that automatically copies files from another folder on your computer to your SkyDrive folder. For example, let’s say you want to sync copies of important log files that a program creates in a specific folder. You could use a program that allows you to schedule automatic folder-mirroring, configuring the program to regularly copy the contents of your log folder to your SkyDrive folder. This may be a useful alternative for some use cases, although it isn’t the same as standard syncing. You’ll end up with two copies of the files taking up space on your system, which won’t be ideal for large files. The files also won’t be instantly uploaded to your SkyDrive storage after they’re created, but only after the scheduled task runs. There are many options for this, including Microsoft’s own SyncToy, which continues to work on Windows 8. If you were using the symbolic link trick to automatically sync copies of PC game save files with SkyDrive, you could just install GameSave Manager. It can be configured to automatically create backup copies of your computer’s PC game save files on a schedule, saving them to SkyDrive where they’ll be synced and backed up online. SkyDrive support was completely rewritten for Windows 8.1, so it’s not surprising that this trick no longer works. The ability to use symbolic links in previous versions of SkyDrive was never officially supported, so it’s not surprising to see it break after a rewrite. None of the methods above are as convenient and quick as the old symbolic link method, but they’re the best we can do with the SkyDrive integration Microsoft has given us in Windows 8.1. It’s still possible to use symbolic links to easily sync other folders with competing cloud storage services like Dropbox and Google Drive, so you may want to consider switching away from SkyDrive if this feature is critical to you.

  • MySQL for Excel 1.1.0 GA has been released

    - by Javier Treviño
    The MySQL Windows Experience Team is proud to announce the release of MySQL for Excel version 1.1.0 GA, one of our newest products contained in the MySQL Installer suite. You can download it from our official Downloads page at http://dev.mysql.com/downloads/installer/. The 1.1.0 release of MySQL for Excel introduces the following features: Edit MySQL Data. Edit MySQL Data This may be the coolest feature so far; users will be able to edit the data in a MySQL table using MS Excel in a very friendly and intuitive way.  Edit Data supports inserting new rows, deleting existing rows and updating existing data as easy as playing with data in an Excel’s spreadsheet and pushing changes back to the server.  Also this version contains the following bug fixes: Enabled the following checkboxes in the Append Data's Advanced Options dialog and added code in the Append Data dialog to use the checkboxes as follows: Automatically store the column mapping for the given table     If checked the current mapping will be stored automatically after clicking the Append button if the append operation is successful and there is no mapping for the current connection.schema.table already; the new mapping is stored with a proposed name of Mapping. Reload stored column mapping for the selected table automatically     If checked the first Stored Mapping found where all column names in the source grid match all column names in the target grid is automatically selected and applied when the Append Data dialog is loaded. Fixed code in Append Data that applies a stored column mapping to skip target columns where the associated mapping is empty (saved as a -1). Enclosed the Add-In's startup code in a try-catch block in order to log any possible error thrown during startup; and added information messages to the log at the beginning of the Add-In's startup code and at the end of the shutdown code.  Also changed the wrapper method that calls the MySQLUtility to write messages to the log to make logging easier, thus changed the log call throughout all the code that contains a try-catch block. Added code to the main wix configuration file to check if a newer version is already installed and if so abort the installation Fixed code to refresh the Import Procedure Form's preview grid's data source to repaint its contents every time the Call button is pressed. Added code to re-pull connections after connections are migrated from Excel to Workbench. Fixed code so when the Append Data's Automatic Mapping is performed any subsequent change on a mapping resets the mapping to a Manual Mapping. Added code to the InfoDialog class to set the button text to "Show Details" or "Hide Details" depending on the status of the Details text container. Fixed a GUID in the main wix configuration file so now previous versions are uninstalled during a new installation. Added an option to the Export Data's Advanced Options dialog to remove columns with no data, by default the Export Dialog will only flag those columns as Excluded. Added code to display a warning and paint a column red if the column name in the Export Data dialog is not set, display a warning if the table name is not set, and stack warnings but not display them if a column is Excluded, warnings are displayed normally for columns if they are not Excluded anymore.  Added code to prevent the Append and Export of Data if more than 1 selection is made (selecting more than 1 area holding the Ctrl key while selecting Excel cells). Fixed problem that prevented MySQL for Excel from loading when Display settings in Windows 7 is set to Adjust to Best Performance (Oracle bug 14521405 - UNHANDLED EXCEPTION IS THROWN WHEN LOADING MYSQL FOR EXCEL). Fixed code that renames the auto-generated Primary Key column when the Table name changes since it was not detecting if a column with the same name already existed in the table. The column duplication was not actually happening, it looked that way because the automatically generated PK column was not detecting a column had that same name. Fixed code in Export Data dialog to always set an empty string instead of null to the MySQLDataColumn properties that stores MySQL data types (MySQLDataType, RowsFrom1stDataType and RowsFrom2ndDataType). Added code to display a warning and color red a column which Data Type has not been set by the user or has been manually cleared. Added code to output to the application log exception messages consistently in all places where exceptions are catched. A series of blog posts explaining the new Edit MySQL Data feature and the other existing features are coming in this blog. You can access the MySQL for Excel documentation at http://dev.mysql.com/doc/refman/5.5/en/mysql-for-excel.html You can also post questions on our MySQL for Excel forum found at http://forums.mysql.com/. You can also post questions on our MySQL for Excel forum found at http://forums.mysql.com/. Enjoy and thanks for the support!

  • Beginner Geek: How to Use Multiple Monitors to Be More Productive

    - by Chris Hoffman
    Many people swear by multiple monitors, whether they’re geeks or just people who need to be productive. Why use just one monitor when you can use two or more and see more at once? Additional monitors allow you to expand your desktop, getting more screen real estate for your open programs. Windows makes it very easy to set up additional monitors, and your computer probably has the necessary ports. Why Use Multiple Monitors? Multiple monitors give you more screen real estate. Hook up multiple monitors to a computer and you can move your mouse back and forth between them, dragging programs between monitors as if you had an extra-large desktop. People who swear by multiple monitors use them to display multiple things on-screen at a time. Rather than Alt+Tabbing and task switching to glance at another window, you can just look over with your eyes and then look back to the program you’re using. Some examples of use cases for multiple monitors include: Coders who want to view their code on one display with the other display reserved for documentation. They can just glance over at the documentation and look back at their primary workspace. Anyone who needs to view something while working. Viewing a web page while writing an email, viewing another document while writing an something, or working with two large spreadsheets and having both visible at once. People who need to keep an eye on information, whether it’s email or up-to-date statistics, while working. Gamers who want to see more of the game world, extending the game across multiple displays. Geeks who just want to watch a video on one screen while doing something else on the other screen. Hooking Up Multiple Monitors Hooking up an additional monitor to your computer should be very simple. Most new computers come with more than one port for a monitor — whether DVI, HDMI, the older VGA port, or a mix. Some computers may include splitter cables that allow you to connect multiple monitors to a single port. Most laptops also come with ports that allow you to hook up an external monitor. Plug a monitor into your laptop’s DVI or VGA port and Windows will allow you to use both your laptop’s integrated display and the external monitor at once. This all depends on the ports your computer has and how your monitor connects. If you have an old VGA monitor lying around and you have a modern laptop with only DVI or HDMI connectors, you may need an adapter that allows you to plug your monitor’s VGA cable into the new port. Be sure to take your computer’s ports into account before you get another monitor for it. Managing Multiple Monitors With Windows Windows makes using multiple monitors easy. Just plug the monitor into the appropriate port on your computer and Windows should automatically extend your desktop onto it. You can now just drag and drop windows between monitors. To control how this works, right-click your Windows desktop and select Screen resolution. Choose an option from the Multiple displays box. The Extend option extends your desktop onto an additional monitor, while the other options are mainly useful if you’re using an additional monitor for presentations — for example, you could mirror your laptop’s desktop onto a large monitor or blank your laptop’s screen while it’s connected to a larger display. Be sure to arrange your monitors properly so Windows understands how your monitors are physically positioned. Windows 8 allows you to extend your Windows taskbar across multiple monitors. You’ll find this option in the taskbar’s options window — right-click the taskbar and select Properties. You can also choose where you want Windows to display taskbar buttons for open programs — on any monitor’s taskbar or only on the taskbar on the associated monitor. Windows 7 doesn’t have these convenient features built-in — your second monitor won’t have a taskbar. To extend your taskbar onto an additional monitor, you’ll need a third-party utility like the free and open-source Dual Monitor Taskbar. If you just have a single monitor, you can also use the Aero Snap feature to quickly place multiple Windows applications side by side. On Windows 7 or 8, press Windows Key + Left or Windows Key + Right to make the current window take up the left or right half of your display. You could also drag any window’s title bar to the left or right edges of your screen and release the window. How useful this feature is depends on your monitor’s size and resolution. If you have a large, high-resolution monitor, it will allow you to see a lot. If you have a smaller laptop monitor with the seemingly standard 1366×768 resolution, you won’t be able to see much of each snapped window at once, so snapping windows may not be practical.

  • Part 8: How to name EBS Customizations

    - by volker.eckardt(at)oracle.com
    You might wonder why I am discussing this here. The reason is simple: nearly every project has a bit different naming conventions, which makes a the life always a bit complicated (for developers, but also setup responsible, and also for consultants).  Although we always create a document to describe the technical object naming conventions, I have rarely seen a dedicated document  with functional naming conventions. To be precisely, from my stand point, there should always be one global naming definition for an implementation! Let me discuss some related questions: What is the best convention for the customization reference? How to name database objects (tables, packages etc.)? How to name functional objects like Value Sets, Concurrent Programs, etc. How to separate customizations from standard objects best? What is the best convention for the customization reference? The customization reference is the key you use to reference your customization from other lists, from the project plan etc. Usually it is something like XXHU_CONV_22 (HU=customer abbreviation, CONV=Conversion object #22) or XXFA_DEPRN_RPT_02 (FA=Fixed Assets, DEPRN=Short object group, here depreciation, RPT=Report, 02=2nd report in this area) As this is just a reference (not an object name yet), I would prefer the second option. XX=Customization, FA=Main EBS Module linked (you may have sometimes more, but FA is the main) DEPRN_RPT=Short name to specify the customization 02=a unique number Important here is that the HU isn’t used, because XX is enough to mark a custom object, and the 3rd+4th char can be used by the EBS module short name. How to name database objects (tables, packages etc.)? I was leading different developer teams, and I know that one common way is it to take the Customization reference and add more chars behind to classify the object (like _V for view and _T1 for triggers etc.). The only concern I have with this approach is the reusability. If you name your view XXFA_DEPRN_RPT_02_V, no one will by choice reuse this nice view, as it seams to be specific for this CEMLI. My suggestion is rather to name the view XXFA_DEPRN_PERIODS_V and allow herewith reusability for other CEMLIs (although the view will be deployed primarily with CEMLI package XXFA_DEPRN_RPT_02). (check also one of the following Blogs where I will talk about deployment.) How to name Value Sets, Concurrent Programs, etc. For Value Sets I would go with the same convention as for database objects, starting with XX<Module> …. For Concurrent Programs the situation is a bit different. This “object” is seen and used by a lot of users, and they will search for. In many projects it is common to start again with the company short name, or with XX. My proposal would differ. If you have created your own report and you name it “XX: Invoice Report”, the user has to remember that this report does not start with “I”, it starts with X. Would you like typing an X if you are looking for an Invoice report? No, you wouldn’t! So my advise would be to name it:   “Invoice Report (XXAP)”. Still we know it is custom (because of the XXAP), but the end user will type the key “i” to get it (and will see similar reports starting also with “i”). I hope that the general schema behind has now become obvious. How to separate customizations from standard objects best? I would not have this section here if the naming would not play an important role. Unfortunately, we can not always link a custom application to our own object, therefore the naming is really important. In the file system structure we use our $XXyy_TOP, in JAVA_TOP it is perhaps also “xx” in front. But in the database itself? Although there are different concepts in place, still many implementations are using the standard “apps” approach, means custom objects are stored in the apps schema (which should not cause any trouble). Final advise: review the naming conventions regularly, once a month. You may have to add more! And, publish them! To summarize: Technical and functional customized objects should always follow a naming convention. This naming convention should be project wide, and only one place shall be used to maintain (like in a Wiki). If the name is for the end user, rather put a customization identifier at the end; if it is an internal name, start with XX…

  • Cold Start

    - by antony.reynolds
    Well we had snow drifts 3ft deep on Saturday so it must be spring time.  In preparation for Spring we decided to move the lawn tractor.  Of course after sitting in the garage all winter it refused to start.  I then come into the office and need to start my 11g SOA Suite installation.  I thought about this and decided my tractor might be cranky but at least I can script the startup of my SOA Suite 11g installation. So with this in mind I created 6 scripts.  I created them for Linux but they should translate to Windows without too many problems.  This is left as an exercise to the reader, note you will have to hardcode more than I did in the Linux scripts and create separate script files for the sqlplus and WLST sections. Order to start things I believe there should be order in all things, especially starting the SOA Suite.  So here is my preferred order. Start Database This is need by EM and the rest of SOA Suite so best to start it before the Admin Server and managed servers. Start Node Manager on all machines This is needed if you want the scripts to work across machines. Start Admin Server Once this is done in theory you can manually stat the managed servers using WebLogic console.  But then you have to wait for console to be available.  Scripting it all is quicker and easier way of starting. Start Managed Servers & Clusters Best to start them one per physical machine at a time to avoid undue load on the machines.  Non-clustered install will have just soa_server1 and bam_serv1 by default.  Clusters will have at least SOA and BAM clusters that can be started as a group or individually.  I have provided scripts for standalone servers, but easy to change them to work with clusters. Starting Database I have provided a very primitive script (available here) to start the database, the listener and the DB console.  The section highlighted in red needs to match your database name. #!/bin/sh echo "##############################" echo "# Setting Oracle Environment #" echo "##############################" . oraenv <<-EOF orcl EOF echo "#####################" echo "# Starting Database #" echo "#####################" sqlplus / as sysdba <<-EOF startup exit EOF echo "#####################" echo "# Starting Listener #" echo "#####################" lsnrctl start echo "######################" echo "# Starting dbConsole #" echo "######################" emctl start dbconsole read -p "Hit <enter> to continue" Starting SOA Suite My script for starting the SOA Suite (available here) breaks the task down into five sections. Setting the Environment First set up the environment variables.  The variables highlighted in red probably need changing for your environment. #!/bin/sh echo "###########################" echo "# Setting SOA Environment #" echo "###########################" export MW_HOME=~oracle/Middleware11gPS1 export WL_HOME=$MW_HOME/wlserver_10.3 export ORACLE_HOME=$MW_HOME/Oracle_SOA export DOMAIN_NAME=soa_std_domain export DOMAIN_HOME=$MW_HOME/user_projects/domains/$DOMAIN_NAME Starting the Node Manager I start node manager with a nohup to stop it exiting when the script terminates and I redirect the standard output and standard error to a file in a logs directory. cd $DOMAIN_HOME echo "#########################" echo "# Starting Node Manager #" echo "#########################" nohup $WL_HOME/server/bin/startNodeManager.sh >logs/NodeManager.out 2>&1 & Starting the Admin Server I had problems starting the Admin Server from Node Manager so I decided to start it using the command line script.  I again use nohup and redirect output. echo "#########################" echo "# Starting Admin Server #" echo "#########################" nohup ./startWebLogic.sh >logs/AdminServer.out 2>&1 & Starting the Managed Servers I then used WLST (WebLogic Scripting Tool) to start the managed servers.  First I waited for the Admin Server to come up by putting a connect command in a loop.  I could have put the WLST commands into a separate script file but I wanted to reduce the number of files I was using and so used redirected input (here syntax). $ORACLE_HOME/common/bin/wlst.sh <<-EOF import time sleep=time.sleep print "#####################################" print "# Waiting for Admin Server to Start #" print "#####################################" while True:   try:     connect(adminServerName="AdminServer")     break   except:     sleep(10) I then start the SOA server and tell WLST to wait until it is started before returning.  If starting a cluster then the start command would be modified accordingly to start the SOA cluster. print "#######################" print "# Starting SOA Server #" print "#######################" start(name="soa_server1", block="true") I then start the BAM server in the same way as the SOA server. print "#######################" print "# Starting BAM Server #" print "#######################" start(name="bam_server1", block="true") EOF Finally I let people know the servers are up and wait for input in case I am running in a separate window, in which case the result would be lost without the read command. echo "#####################" echo "# SOA Suite Started #" echo "#####################" read -p "Hit <enter> to continue" Stopping the SOA Suite My script for shutting down the SOA Suite (available here)  is basically the reverse of my startup script.  After setting the environment I connect to the Admin Server using WLST and shut down the managed servers and the admin server.  Again the script would need modifying for a cluster. Stopping the Servers If I cannot connect to the Admin Server I try to connect to the node manager, in case the Admin Server is down but the managed servers are up. #!/bin/sh echo "###########################" echo "# Setting SOA Environment #" echo "###########################" export MW_HOME=~oracle/Middleware11gPS1 export WL_HOME=$MW_HOME/wlserver_10.3 export ORACLE_HOME=$MW_HOME/Oracle_SOA export DOMAIN_NAME=soa_std_domain export DOMAIN_HOME=$MW_HOME/user_projects/domains/$DOMAIN_NAME cd $DOMAIN_HOME $MW_HOME/Oracle_SOA/common/bin/wlst.sh <<-EOF try:   print("#############################")   print("# Connecting to AdminServer #")   print("#############################")   connect(username='weblogic',password='welcome1',url='t3://localhost:7001') except:   print "#########################################"   print "#   Unable to connect to Admin Server   #"   print "# Attempting to connect to Node Manager #"   print "#########################################"   nmConnect(domainName=os.getenv("DOMAIN_NAME")) print "#######################" print "# Stopping BAM Server #" print "#######################" shutdown('bam_server1') print "#######################" print "# Stopping SOA Server #" print "#######################" shutdown('soa_server1') print "#########################" print "# Stopping Admin Server #" print "#########################" shutdown('AdminServer') disconnect() nmDisconnect() EOF Stopping the Node Manager I stopped the node manager by searching for the java node manager process using the ps command and then killing that process. echo "#########################" echo "# Stopping Node Manager #" echo "#########################" kill -9 `ps -ef | grep java | grep NodeManager |  awk '{print $2;}'` echo "#####################" echo "# SOA Suite Stopped #" echo "#####################" read -p "Hit <enter> to continue" Stopping the Database Again my script for shutting down the database is the reverse of my start script.  It is available here.  The only change needed might be to the database name. #!/bin/sh echo "##############################" echo "# Setting Oracle Environment #" echo "##############################" . oraenv <<-EOF orcl EOF echo "######################" echo "# Stopping dbConsole #" echo "######################" emctl stop dbconsole echo "#####################" echo "# Stopping Listener #" echo "#####################" lsnrctl stop echo "#####################" echo "# Stopping Database #" echo "#####################" sqlplus / as sysdba <<-EOF shutdown immediate exit EOF read -p "Hit <enter> to continue" Cleaning Up Cleaning SOA Suite I often run tests and want to clean up all the log files.  The following script (available here) does this for the WebLogic servers in a given domain on a machine.  After setting the domain I just remove all files under the servers logs directories.  It also cleans up the log files I created with my startup scripts.  These scripts could be enhanced to copy off the log files if you needed them but in my test environments I don’t need them and would prefer to reclaim the disk space. #!/bin/sh echo "###########################" echo "# Setting SOA Environment #" echo "###########################" export MW_HOME=~oracle/Middleware11gPS1 export WL_HOME=$MW_HOME/wlserver_10.3 export ORACLE_HOME=$MW_HOME/Oracle_SOA export DOMAIN_NAME=soa_std_domain export DOMAIN_HOME=$MW_HOME/user_projects/domains/$DOMAIN_NAME echo "##########################" echo "# Cleaning SOA Log Files #" echo "##########################" cd $DOMAIN_HOME rm -Rf logs/* servers/*/logs/* read -p "Hit <enter> to continue" Cleaning Database I also created a script to clean up the dump files of an Oracle database instance and also the EM log files (available here).  This relies on the machine name being correct as the EM log files are stored in a directory that is based on the hostname and the Oracle SID. #!/bin/sh echo "##############################" echo "# Setting Oracle Environment #" echo "##############################" . oraenv <<-EOF orcl EOF echo "#############################" echo "# Cleaning Oracle Log Files #" echo "#############################" rm -Rf $ORACLE_BASE/admin/$ORACLE_SID/*dump/* rm -Rf $ORACLE_HOME/`hostname`_$ORACLE_SID/sysman/log/* read -p "Hit <enter> to continue" Summary Hope you find the above scripts useful.  They certainly stop me hanging around waiting for things to happen on my test machine and make it easy to run a test, change parameters, bounce the SOA Suite and clean the logs between runs so I can see exactly what is happening. Now I need to get that mower started…

  • The Inkremental Architect&acute;s Napkin - #4 - Make increments tangible

    - by Ralf Westphal
    Originally posted on: http://geekswithblogs.net/theArchitectsNapkin/archive/2014/06/12/the-inkremental-architectacutes-napkin---4---make-increments-tangible.aspxThe driver of software development are increments, small increments, tiny increments. With an increment being a slice of the overall requirement scope thin enough to implement and get feedback from a product owner within 2 days max. Such an increment might concern Functionality or Quality.[1] To make such high frequency delivery of increments possible, the transition from talking to coding needs to be as easy as possible. A user story or some other documentation of what´s supposed to get implemented until tomorrow evening at latest is one side of the medal. The other is where to put the logic in all of the code base. To implement an increment, only logic statements are needed. Functionality like Quality are just about expressions and control flow statements. Think of Assembler code without the CALL/RET instructions. That´s all is needed. Forget about functions, forget about classes. To make a user happy none of that is really needed. It´s just about the right expressions and conditional executions paths plus some memory allocation. Automatic function inlining of compilers which makes it clear how unimportant functions are for delivering value to users at runtime. But why then are there functions? Because they were invented for optimization purposes. We need them for better Evolvability and Production Efficiency. Nothing more, nothing less. No software has become faster, more secure, more scalable, more functional because we gathered logic under the roof of a function or two or a thousand. Functions make logic easier to understand. Functions make us faster in producing logic. Functions make it easier to keep logic consistent. Functions help to conserve memory. That said, functions are important. They are even the pivotal element of software development. We can´t code without them - whether you write a function yourself or not. Because there´s always at least one function in play: the Entry Point of a program. In Ruby the simplest program looks like this:puts "Hello, world!" In C# more is necessary:class Program { public static void Main () { System.Console.Write("Hello, world!"); } } C# makes the Entry Point function explicit, not so Ruby. But still it´s there. So you can think of logic always running in some function. Which brings me back to increments: In order to make the transition from talking to code as easy as possible, it has to be crystal clear into which function you should put the logic. Product owners might be content once there is a sticky note a user story on the Scrum or Kanban board. But developers need an idea of what that sticky note means in term of functions. Because with a function in hand, with a signature to run tests against, they have something to focus on. All´s well once there is a function behind whose signature logic can be piled up. Then testing frameworks can be used to check if the logic is correct. Then practices like TDD can help to drive the implementation. That´s why most code katas define exactly how the API of a solution should look like. It´s a function, maybe two or three, not more. A requirement like “Write a function f which takes this as parameters and produces such and such output by doing x” makes a developer comfortable. Yes, there are all kinds of details to think about, like which algorithm or technology to use, or what kind of state and side effects to consider. Even a single function not only must deliver on Functionality, but also on Quality and Evolvability. Nevertheless, once it´s clear which function to put logic in, you have a tangible starting point. So, yes, what I´m suggesting is to find a single function to put all the logic in that´s necessary to deliver on a the requirements of an increment. Or to put it the other way around: Slice requirements in a way that each increment´s logic can be located under the roof of a single function. Entry points Of course, the logic of a software will always be spread across many, many functions. But there´s always an Entry Point. That´s the most important function for each increment, because that´s the root to put integration or even acceptance tests on. A batch program like the above hello-world application only has a single Entry Point. All logic is reached from there, regardless how deep it´s nested in classes. But a program with a user interface like this has at least two Entry Points: One is the main function called upon startup. The other is the button click event handler for “Show my score”. But maybe there are even more, like another Entry Point being a handler for the event fired when one of the choices gets selected; because then some logic could check if the button should be enabled because all questions got answered. Or another Entry Point for the logic to be executed when the program is close; because then the choices made should be persisted. You see, an Entry Point to me is a function which gets triggered by the user of a software. With batch programs that´s the main function. With GUI programs on the desktop that´s event handlers. With web programs that´s handlers for URL routes. And my basic suggestion to help you with slicing requirements for Spinning is: Slice them in a way so that each increment is related to only one Entry Point function.[2] Entry Points are the “outer functions” of a program. That´s where the environment triggers behavior. That´s where hardware meets software. Entry points always get called because something happened to hardware state, e.g. a key was pressed, a mouse button clicked, the system timer ticked, data arrived over a wire.[3] Viewed from the outside, software is just a collection of Entry Point functions made accessible via buttons to press, menu items to click, gestures, URLs to open, keys to enter. Collections of batch processors I´d thus say, we haven´t moved forward since the early days of software development. We´re still writing batch programs. Forget about “event-driven programming” with its fancy GUI applications. Software is just a collection of batch processors. Earlier it was just one per program, today it´s hundreds we bundle up into applications. Each batch processor is represented by an Entry Point as its root that works on a number of resources from which it reads data to process and to which it writes results. These resources can be the keyboard or main memory or a hard disk or a communication line or a display. Together many batch processors - large and small - form applications the user perceives as a single whole: Software development that way becomes quite simple: just implement one batch processor after another. Well, at least in principle ;-) Features Each batch processor entered through an Entry Point delivers value to the user. It´s an increment. Sometimes its logic is trivial, sometimes it´s very complex. Regardless, each Entry Point represents an increment. An Entry Point implemented thus is a step forward in terms of Agility. At the same time it´s a tangible unit for developers. Therefore, identifying the more or less numerous batch processors in a software system is a rewarding task for product owners and developers alike. That´s where user stories meet code. In this example the user story translates to the Entry Point triggered by clicking the login button on a dialog like this: The batch then retrieves what has been entered via keyboard, loads data from a user store, and finally outputs some kind of response on the screen, e.g. by displaying an error message or showing the next dialog. This is all very simple, but you see, there is not just one thing happening, but several. Get input (email address, password) Load user for email address If user not found report error Check password Hash password Compare hash to hash stored in user Show next dialog Viewed from 10,000 feet it´s all done by the Entry Point function. And of course that´s technically possible. It´s just a bunch of logic and calling a couple of API functions. However, I suggest to take these steps as distinct aspects of the overall requirement described by the user story. Such aspects of requirements I call Features. Features too are increments. Each provides some (small) value of its own to the user. Each can be checked individually by a product owner. Instead of implementing all the logic behind the Login() entry point at once you can move forward increment by increment, e.g. First implement the dialog, let the user enter any credentials, and log him/her in without any checks. Features 1 and 4. Then hard code a single user and check the email address. Features 2 and 2.1. Then check password without hashing it (or use a very simple hash like the length of the password). Features 3. and 3.2 Replace hard coded user with a persistent user directoy, but a very simple one, e.g. a CSV file. Refinement of feature 2. Calculate the real hash for the password. Feature 3.1. Switch to the final user directory technology. Each feature provides an opportunity to deliver results in a short amount of time and get feedback. If you´re in doubt whether you can implement the whole entry point function until tomorrow night, then just go for a couple of features or even just one. That´s also why I think, you should strive for wrapping feature logic into a function of its own. It´s a matter of Evolvability and Production Efficiency. A function per feature makes the code more readable, since the language of requirements analysis and design is carried over into implementation. It makes it easier to apply changes to features because it´s clear where their logic is located. And finally, of course, it lets you re-use features in different context (read: increments). Feature functions make it easier for you to think of features as Spinning increments, to implement them independently, to let the product owner check them for acceptance individually. Increments consist of features, entry point functions consist of feature functions. So you can view software as a hierarchy of requirements from broad to thin which map to a hierarchy of functions - with entry points at the top.   I like this image of software as a self-similar structure on many levels of abstraction where requirements and code match each other. That to me is true agile design: the core tenet of Agility to move forward in increments is carried over into implementation. Increments on paper are retained in code. This way developers can easily relate to product owners. Elusive and fuzzy requirements are not tangible. Software production is moving forward through requirements one increment at a time, and one function at a time. In closing Product owners and developers are different - but they need to work together towards a shared goal: working software. So their notions of software need to be made compatible, they need to be connected. The increments of the product owner - user stories and features - need to be mapped straightforwardly to something which is relevant to developers. To me that´s functions. Yes, functions, not classes nor components nor micro services. We´re talking about behavior, actions, activities, processes. Their natural representation is a function. Something has to be done. Logic has to be executed. That´s the purpose of functions. Later, classes and other containers are needed to stay on top of a growing amount of logic. But to connect developers and product owners functions are the appropriate glue. Functions which represent increments. Can there always be such a small increment be found to deliver until tomorrow evening? I boldly say yes. Yes, it´s always possible. But maybe you´ve to start thinking differently. Maybe the product owner needs to start thinking differently. Completion is not the goal anymore. Neither is checking the delivery of an increment through the user interface of a software. Product owners need to become comfortable using test beds for certain features. If it´s hard to slice requirements thin enough for Spinning the reason is too little knowledge of something. Maybe you don´t yet understand the problem domain well enough? Maybe you don´t yet feel comfortable with some tool or technology? Then it´s time to acknowledge this fact. Be honest about your not knowing. And instead of trying to deliver as a craftsman officially become a researcher. Research an check back with the product owner every day - until your understanding has grown to a level where you are able to define the next Spinning increment. ? Sometimes even thin requirement slices will cover several Entry Points, like “Add validation of email addresses to all relevant dialogs.” Validation then will it put into a dozen functons. Still, though, it´s important to determine which Entry Points exactly get affected. That´s much easier, if strive for keeping the number of Entry Points per increment to 1. ? If you like call Entry Point functions event handlers, because that´s what they are. They all handle events of some kind, whether that´s palpable in your code or note. A public void btnSave_Click(object sender, EventArgs e) {…} might look like an event handler to you, but public static void Main() {…} is one also - for then event “program started”. ?

  • Windows could not start Apache 2 on the local computer

    - by andig
    After installing PHP 5.3, Windows is unable to start Apache 2.2. Apache's error log is empty, no error message on startup: C:\Programme\Apache\bin>httpd -k start C:\Programme\Apache\bin>httpd -k stop The Apache2.2 service is not started. C:\Programme\Apache\bin>httpd -k config Reconfiguring the Apache2.2 service The Apache2.2 service is successfully installed. Testing httpd.conf.... Errors reported here must be corrected before the service can be started. I have no clue where to look for the cause. php5apache2_2.dll is copied to the Apache modules folder. The configuration looks like this: LoadModule php5_module modules/php5apache2_2.dll PHPIniDir "C:/programme/php" Where and how can I start diagnosis? The only hint I have so far is that startup fails as soon as a PHP module is enabled in the configuration. Is there a way to get more details out of the Apache startup process? This is the http.conf: # # This is the main Apache HTTP server configuration file. It contains the # configuration directives that give the server its instructions. # See <URL:http://httpd.apache.org/docs/2.2> for detailed information. # In particular, see # <URL:http://httpd.apache.org/docs/2.2/mod/directives.html> # for a discussion of each configuration directive. # # Do NOT simply read the instructions in here without understanding # what they do. They're here only as hints or reminders. If you are unsure # consult the online docs. You have been warned. # # Configuration and logfile names: If the filenames you specify for many # of the server's control files begin with "/" (or "drive:/" for Win32), the # server will use that explicit path. If the filenames do *not* begin # with "/", the value of ServerRoot is prepended -- so "logs/foo.log" # with ServerRoot set to "C:/Programme/Apache" will be interpreted by the # server as "C:/Programme/Apache/logs/foo.log". # # NOTE: Where filenames are specified, you must use forward slashes # instead of backslashes (e.g., "c:/apache" instead of "c:\apache"). # If a drive letter is omitted, the drive on which httpd.exe is located # will be used by default. It is recommended that you always supply # an explicit drive letter in absolute paths to avoid confusion. # # ServerRoot: The top of the directory tree under which the server's # configuration, error, and log files are kept. # # Do not add a slash at the end of the directory path. If you point # ServerRoot at a non-local disk, be sure to point the LockFile directive # at a local disk. If you wish to share the same ServerRoot for multiple # httpd daemons, you will need to change at least LockFile and PidFile. # ServerRoot "C:/Programme/Apache" # # Listen: Allows you to bind Apache to specific IP addresses and/or # ports, instead of the default. See also the <VirtualHost> # directive. # # Change this to Listen on specific IP addresses as shown below to # prevent Apache from glomming onto all bound IP addresses. # #Listen 12.34.56.78:80 Listen 80 # # Dynamic Shared Object (DSO) Support # # To be able to use the functionality of a module which was built as a DSO you # have to place corresponding `LoadModule' lines at this location so the # directives contained in it are actually available _before_ they are used. # Statically compiled modules (those listed by `httpd -l') do not need # to be loaded here. # # Example: # LoadModule foo_module modules/mod_foo.so # LoadModule actions_module modules/mod_actions.so LoadModule alias_module modules/mod_alias.so LoadModule asis_module modules/mod_asis.so LoadModule auth_basic_module modules/mod_auth_basic.so #LoadModule auth_digest_module modules/mod_auth_digest.so #LoadModule authn_alias_module modules/mod_authn_alias.so #LoadModule authn_anon_module modules/mod_authn_anon.so #LoadModule authn_dbd_module modules/mod_authn_dbd.so #LoadModule authn_dbm_module modules/mod_authn_dbm.so LoadModule authn_default_module modules/mod_authn_default.so LoadModule authn_file_module modules/mod_authn_file.so #LoadModule authnz_ldap_module modules/mod_authnz_ldap.so #LoadModule authz_dbm_module modules/mod_authz_dbm.so LoadModule authz_default_module modules/mod_authz_default.so LoadModule authz_groupfile_module modules/mod_authz_groupfile.so LoadModule authz_host_module modules/mod_authz_host.so #LoadModule authz_owner_module modules/mod_authz_owner.so LoadModule authz_user_module modules/mod_authz_user.so LoadModule autoindex_module modules/mod_autoindex.so #LoadModule cache_module modules/mod_cache.so #LoadModule cern_meta_module modules/mod_cern_meta.so LoadModule cgi_module modules/mod_cgi.so #LoadModule charset_lite_module modules/mod_charset_lite.so #LoadModule dav_module modules/mod_dav.so #LoadModule dav_fs_module modules/mod_dav_fs.so #LoadModule dav_lock_module modules/mod_dav_lock.so #LoadModule dbd_module modules/mod_dbd.so #LoadModule deflate_module modules/mod_deflate.so LoadModule dir_module modules/mod_dir.so #LoadModule disk_cache_module modules/mod_disk_cache.so #LoadModule dumpio_module modules/mod_dumpio.so LoadModule env_module modules/mod_env.so #LoadModule expires_module modules/mod_expires.so #LoadModule ext_filter_module modules/mod_ext_filter.so #LoadModule file_cache_module modules/mod_file_cache.so #LoadModule filter_module modules/mod_filter.so #LoadModule headers_module modules/mod_headers.so #LoadModule ident_module modules/mod_ident.so #LoadModule imagemap_module modules/mod_imagemap.so LoadModule include_module modules/mod_include.so #LoadModule info_module modules/mod_info.so LoadModule isapi_module modules/mod_isapi.so #LoadModule ldap_module modules/mod_ldap.so #LoadModule logio_module modules/mod_logio.so LoadModule log_config_module modules/mod_log_config.so #LoadModule log_forensic_module modules/mod_log_forensic.so #LoadModule mem_cache_module modules/mod_mem_cache.so LoadModule mime_module modules/mod_mime.so #LoadModule mime_magic_module modules/mod_mime_magic.so LoadModule negotiation_module modules/mod_negotiation.so #LoadModule proxy_module modules/mod_proxy.so #LoadModule proxy_ajp_module modules/mod_proxy_ajp.so #LoadModule proxy_balancer_module modules/mod_proxy_balancer.so #LoadModule proxy_connect_module modules/mod_proxy_connect.so #LoadModule proxy_ftp_module modules/mod_proxy_ftp.so #LoadModule proxy_http_module modules/mod_proxy_http.so #LoadModule proxy_scgi_module modules/mod_proxy_scgi.so #LoadModule reqtimeout_module modules/mod_reqtimeout.so #LoadModule rewrite_module modules/mod_rewrite.so LoadModule setenvif_module modules/mod_setenvif.so #LoadModule speling_module modules/mod_speling.so #LoadModule ssl_module modules/mod_ssl.so #LoadModule status_module modules/mod_status.so #LoadModule substitute_module modules/mod_substitute.so #LoadModule unique_id_module modules/mod_unique_id.so #LoadModule userdir_module modules/mod_userdir.so #LoadModule usertrack_module modules/mod_usertrack.so #LoadModule version_module modules/mod_version.so #LoadModule vhost_alias_module modules/mod_vhost_alias.so #!!

  • What does 'useLegacyV2RuntimeActivationPolicy' do in the .NET 4 config?

    - by Cameron MacFarland
    While converting a project that used SlimDX, and therefore has unmanaged code, to .NET 4.0 I ran into the following error: Mixed mode assembly is built against version 'v2.0.50727' of the runtime and cannot be loaded in the 4.0 runtime without additional configuration information. Googling around gave me the solution, which is to add this to the applications config: <configuration> <startup useLegacyV2RuntimeActivationPolicy="true"> <supportedRuntime version="v4.0"/> </startup> </configuration> My question is, what is the useLegacyV2RuntimeActivationPolicy doing? I can't find any documentation about it.
