• Advancing my Embedded knowledge.....with a CS degree.

  - by Mercfh

  So I graduated last December with a B.S. in Computer Science, in a pretty good well known engineering college. However towards the end I realized that I actually like Assembly/Lower level C programming more than I actually enjoy higher level abstracted OO stuff. (Like I Programmed my own Device Drivers for USB stuff in Linux, stuff like that) But.....I mean we really didn't concentrate much on that in college, perhaps an EE/CE degree would've been better, but I knew the classes......and things weren't THAT much different. I've messed around with Atmel AVR's/Arduino stuff (Mostly robotics) and Linux Kernals/Device Drivers. but I really want to enhance my skills and maybe one day get a job doing embedded stuff. (I have a job now, it's An entry level software dev/tester job, it's a good job but not exactly what my passion lies in) (Im pretty good with C and certain ASM's for specific microcontrollers) Is this even possible with a CS degree? or am I screwed? (since technically my degree usually doesn't involve much embedded stuff) If Im NOT screwed then what should I be studying/learning? How would I even go about it........ I guess I could eventually say "Experienced with XXXX Microcontrollers/ASM/etc...." but still, it wouldn't be the same as having a CE/EE degree. Also....going back to college isn't an option. just fyi. edit: Any book recommendations for "getting used to this stuff" I have ARM System-on-Chip Architecture (2nd edition) it's good.....for ARM stuff lol

• TechEd India Recap

  Last week I spoke at TechEd India and the Visual Studio 2010 launch. It was a great event with over 3,000 attendees, far more than attended the Visual Studio launch in Las Vegas! Senior vice president of the Developer Division at Microsoft, S. Somasegar, did an awesome keynote. I did three sessions: Building applications with OData Building Line of Business Applications with WCF and Silverlight 4.0 Building Silverlight Business Applications with RIA Services Something happened to me that never happened before in my 13+ years of being a professional international speaker: I lost my voice! I was in Indonesia the week before and picked up a small bug and had no voice. This was a new challenge for me, and Microsoft offered to cancel my sessions, but I figured why would I let no voice stop me from delivering my sessions!! So I decided to throw away the slides and just code. I had no voice anyway, ...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors?

• Dynamic filter expressions in an OpenAccess LINQ query

  We had some support questions recently where our customers had the need to combine multiple smaller predicate expressions with either an OR or an AND  logical operators (these will be the || and && operators if you are using C#). And because the code from the answer that we sent to these customers is very interesting, and can easily be refactorred into something reusable, we decided to write this blog post. The key thing that one must know is that if you want your predicate to be translated by OpenAccess ORM to SQL and executed on the server you must have a LINQ Expression that is not compiled. So, let’s say that you have these smaller predicate expressions: Expression<Func<Customer, bool>> filter1 = c => c.City.StartsWith("S");Expression<Func<Customer, bool>> filter2 = c => c.City.StartsWith("M");Expression<Func<Customer, bool>> filter3 = c => c.ContactTitle == "Owner"; And ...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors?

• Need to run a .sh as root on boot or login

  - by Graymayre

  Still new with linux and running ubuntu 12.10 I have a wireless stick (ae2500) which has known issues that has been partially solved using ndiswrapper. However, to use it I must run the same scripts every time I reboot, effectively uninstalling and reinstalling the driver. I made a .sh file to run every time to make it easy, but I must do the sudo login everytime. There are three solutions I am looking for and although not all are necessary to solve this particular problem, I would still like to know them all for learning purposes. run scripts or file.sh on boot (as well as other programs) run scripts or file.sh automatically with root privileges make the install permanent so as not to have to go through the process every time. Any additional information that can help me regarding this that I did not think to ask (including streamlining my commands), or general knowledge, would be greatly appreciated. Following are the contents of the file. I pretty much just made it as I would have entered it. cd ~/ndiswrapper-1.58rc1 sudo modprobe -rf ndiswrapper sudo rm /etc/modprobe.d/ndiswrapper.conf sudo rm -r /etc/ndiswrapper/* sudo depmod -a sudo make uninstall sudo make sudo make install sudo ndiswrapper -i bcmwlhigh5.inf ndiswrapper -l sudo modprobe ndiswrapper

• We'll be at QCon San Francisco!

  - by Carlos Chang

  Oracle Technology Network is a Platinum sponsor at QCon San Francisco. Don’t miss these great developer focused sessions: Shay Shmeltzer - How we simplified Web, Mobile and Cloud development for our own developers? - the Oracle Story Over the past several years, Oracle has beendeveloping a new set of enterprise applications in what is probably one of the largest Java based development project in the world. How do you take 3000 developers and make them productive? How do you insure the delivery of cutting edge UIs for both Mobile and Web channels? How do you enable Cloud based development and deployment? Come and learn how we did it at Oracle, and see how the same technologies and methodologies can apply to your development efforts. Dan Smith - Project Lambda in Java 8 Java SE 8 will include major enhancements to the Java Programming Language and its core libraries.  This suite of new features, known as Project Lambda in the OpenJDK community, includes lambda expressions, default methods, and parallel collections (and much more!).  The result will be a next-generation Java programming experience with more flexibility and better abstractions.   This talk will introduce the new Java features and offer a behind-the-scenes view of how they evolved and why they work the way that they do. Arun Gupta - JSR 356: Building HTML5 WebSocket Applications in Java The family of HTML5 technologies has pushed the pendulum away from rich client technologies and toward ever-more-capable Web clients running on today’s browsers. In particular, WebSocket brings new opportunities for efficient peer-to-peer communication, providing the basis for a new generation of interactive and “live” Web applications. This session examines the efforts under way to support WebSocket in the Java programming model, from its base-level integration in the Java Servlet and Java EE containers to a new, easy-to-use API and toolset that are destined to become part of the standard Java platform. The complete conference schedule is here: http://qconsf.com/sf2012/schedule/wednesday.jsp But wait, there’s more! At the Oracle booth, we’ll also be covering: Oracle ADF Mobile Oracle Developer Cloud Service Oracle ADF Essentials NetBeans Project Easel Hope to see you there!

• apt-cacher ng / upgrade fails from client

  - by todayis23

  I'm running apt-cacher ng on an Ubuntu Hardy server and try to upgrade the packages on a Natty client (which was initially a Maverick). I didn't do anything on the server. On the client I tried two setups. I configure APT to use a http-proxy. On the client I did a "apt-get update" which worked fine, but very slowly. In the acng-report.html I see an entry, which seems to be correct. After verifying Install these packages without verification [y/N]? y "apt-get upgrade" failes with the message: Err http://archive.ubuntu.com/ubuntu/ natty-updates/main libnux-0.9-common all 0.9.48-0ubuntu1.1 503 Name or service not known The GUI update manager fails as well with the message, that untrusted packages will be installed. I edit sources.list and add the server in the correct format to all sources. "apt-get update" is very slowly... and I get a lot of errors like this: W: Failed to fetch http://[::ffff:10.10.10.10]:3142/archive.ubuntu.com/ubuntu/dists/natty/main/binary-i386/Packages 403 Forbidden file type or location After that "apt-get upgrade" says: 0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded. What could be wrong? Is it possible to use apt-cacher ng on an older system for upgrading newer systems? Thank you in advance!

• Eclipse Java Code Formatter in NetBeans Plugin Manager

  - by Geertjan

  Great news for Eclipse refugees everywhere. Benno Markiewicz forked the Eclipse formatter plugin that I blogged about sometime ago (here and here)... and he fixed many bugs, while also adding new features. It's a handy plugin when you're (a) switching from Eclipse to NetBeans and want to continue using your old formatting rules and (b) working in a polyglot IDE team, i.e., now the formatting rules defined in Eclipse can be imported into NetBeans IDE and everyone will happily be able to conform to the same set of formatting standards. And now you can get it directly from Tools | Plugins in NetBeans IDE 7.4: News from Benno on the plugin, received from him today: The plugin is verified by the NetBeans community and available in the Plugin Manager in NetBeans IDE 7.4 (as shown above) and also at the NetBeans Plugin Portal here, where you can also read quite some info about the plugin:  http://plugins.netbeans.org/plugin/50877/eclipse-code-formatter-for-java The issue with empty undo buffer was solved with the help of junichi11: https://github.com/markiewb/eclipsecodeformatter_for_netbeans/issues/18 The issue with the lost breakpoints remains unsolved and there was no further feedback. That is the main reason why the save action isn't activated by default. See also the open known issues at https://github.com/markiewb/eclipsecodeformatter_for_netbeans/issues?state=open Features are as follows:  Global configuration and project specific configuration.  On save action, which is disabled by default. Show the used formatter as a notification, which is enabled by default.  Finally, Benno testifies to the usefulness, stability, and reliability of the plugin: I use the Eclipse formatter provided by this plugin every day at work. Before I commit, I format the sources. It works and that's it. I am pleased with it. Here's where the Eclipse formatter is defined globally in Tools | Options: And here is per-project configuration, i.e., use the Project Properties dialog of any project to override the global settings:  Interested to hear from anyone who tries the plugin and has any feedback of any kind!

• The premier support for Sun Cluster 3.1 ended

  - by JuergenS

  In October 2011 the premier support for Sun Cluster 3.1 ended. See details in Oracle Lifetime Support Policy for Oracle and Sun System Software document. There no 'Extended Support' and the 'Sustaining Support Ends' is indefinite. But for indefinite 'Sustaining Support' I like to point out from the mentioned document (version Sept. 2011) on page 5: Sustaining Support does NOT include: * New program updates, fixes, security alerts, general maintenance releases, selected functionality releases and documentation updates or upgrade tools * Certification with most new third-party products/versions and most new Oracle products * 24 hour commitment and response guidelines for Severity 1 service requests *Previously released fixes or updates that Oracle no longer supports This means Solaris 10 9/10 update9 is the last qualified release for Sun Cluster 3.1. So, Sun Cluster 3.1 is not qualified on Solaris 10 8/11 Update10. Furthermore there is an issue around with SVM patch 145899-06 or higher. This SVM patch is part of Solaris 10 8/11 Update10. The 145899-06 is the first released patch of this number, therefore the support for Sun Cluster 3.1 ends with the previous SVM patches 144622-01 and 139967-02. For details about the known problem with SVM patch 145899-06 please refer to doc 1378828.1. Further this means you should freeze (no patching, no upgrade) your Sun Cluster 3.1 configuration not later than Solaris 10 9/10 update9. Or even better plan an upgrade to Solaris Cluster 3.3 now to get back to full support.

• PASS Summit 2011 &ndash; Part I

  - by Tara Kizer

  What an amazing week I had at PASS Summit 2011 in Seattle, WA!  I hadn’t attended a PASS conference since September of 2005 when it was in Grapevine, Texas.  It has grown so much since then.  I am not sure how many people attended back then, but I’d guesstimate about 1500.  They announced that at this year’s conference there were 4000 attendees.  WOW! Here are my favorite aspects of this conference: Networking! – Not only did I meet a lot of new people, but I also got to meet people in person that I’ve known on the Internet for years like Mladen Prajdic (blog|twitter) and Rob Volk (blog|twitter).  I even met someone that I’d recently helped out in the SQLTeam forums.  Learning – I took a lot of notes during the sessions I attended and plan on blogging very soon about them.  It is amazing the amount of things you learn and the things that you unlearn.  Yes I said unlearn.  Some of the stuff that I thought I knew was either out-dated or just plain wrong.  Fun, fun, fun – To say that this conference was fun would be an understatement.  I had a blast!  I attended the “Welcome Reception and Quizbowl” on Tuesday night, the “Exhibitor Reception” on Wednesday night, and the “Community Appreciation Party” at GameWorks on Thursday night.  There were many other after-hours events to attend, but I had to make my kids a priority at night so I had to get back to my hotel room before 9pm so that I could Skype with them.   It was very entertaining reading and posting with #sqlpass on Twitter.  Twitter has changed the conference experience for the better.  I will definitely be able to do my job better due to attending this conference.  The return on investment is HUGE!

• Best peer-to-peer game architecture

  - by Dejw

  Consider a setup where game clients: have quite small computing resources (mobile devices, smartphones) are all connected to a common router (LAN, hotspot etc) The users want to play a multiplayer game, without an external server. One solution is to host an authoritative server on one phone, which in this case would be also a client. Considering point 1 this solution is not acceptable, since the phone's computing resources are not sufficient. So, I want to design a peer-to-peer architecture that will distribute the game's simulation load among the clients. Because of point 2 the system needn't be complex with regards to optimization; the latency will be very low. Each client can be an authoritative source of data about himself and his immediate environment (for example bullets.) What would be the best approach to designing such an architecture? Are there any known examples of such a LAN-level peer-to-peer protocol? Notes: Some of the problems are addressed here, but the concepts listed there are too high-level for me. Security I know that not having one authoritative server is a security issue, but it is not relevant in this case as I'm willing to trust the clients. Edit: I forgot to mention: it will be a rather fast-paced game (a shooter). Also, I have already read about networking architectures at Gaffer on Games.

• Erlang node acts like it connects, but doesn't [migrated]

  - by Malfist

  I'm trying to setup a distributed network of nodes across a few firewalls and it's not going so well. My application is structured like this: there is a central server that always running a node ([email protected]) and my co-worker's laptops connect to it on startup. This works if we're all in the office, but if someone is at home, they can connect to the masternode, but they fail to connect to the other nodes in the swarm. I.E., erlang fails to gossip correctly. To correct this, I've change epmd's port number and changed the inet_dist_listen ports to a known open port (1755 and 7070 respectively). However, something fishy is going on. I can run net_adm:world() and it reports that it connects to master node, but when I run nodes() I get an empty array. Same with net_adm:ping('[email protected]'). See: Eshell V5.9 (abort with ^G) ([email protected])1> net_adm:world(). ['[email protected]'] ([email protected])2> nodes(). [] ([email protected])3> net_adm:ping('[email protected]'). pong ([email protected])4> nodes(). [] ([email protected])5> What's going on, and how can I fix it?

• Is it safer to use the same IV all times data are encrypted, or use a dynamic IV that is sent together the encrypted text? [closed]

  - by kiamlaluno

  When encrypting data that is then send to a server, is it better to always use the same IV, which is already known from the receiving server, or use a dynamic IV that is then sent to the receiving server? I am referring to the case the remote server receives data from another server, or from a client application, and executes operations on a database table, in the table row identified by the received data. Which of the following PHP snippets is preferable? $iv = mcrypt_create_iv(mcrypt_enc_get_iv_size($td), MCRYPT_RAND); $ks = mcrypt_enc_get_key_size($td); $key = substr(md5('very secret key'), 0, $ks); mcrypt_generic_init($td, $key, $iv); $encrypted = mcrypt_generic($td, 'This is very important data'); send_encripted_data(combine_iv_encrypted_text($iv, $encrypted)); $ks = mcrypt_enc_get_key_size($td); $key = substr(md5('very secret key'), 0, $ks); mcrypt_generic_init($td, $key, $iv); send_encripted_data(mcrypt_generic($td, 'This is very important data')); In which way is one of the snippets more vulnerable than the other one?

• Cleaning Up Online Games with Positive Enforcement

  - by Jason Fitzpatrick

  Anyone who has played online multiplayer games, especially those focused on combat, can attest to how caustic other players can be. League of Legends creators are fighting that, rather successfully, with a positive-reinforcement honor system. The Mary Sue reports: Here’s the background: Six months ago, Riot established Team Player Behavior — affectionately called Team PB&J — a group of experts in psychology, neuroscience, and statistics (already, I am impressed). At the helm is Jeffrey Lin, better known as Dr. Lyte, Riot’s lead designer of social systems. As quoted in a recent article at Polygon: We want to show other companies and other games that it is possible to tackle player behavior, and with certain systems and game design tools, we can shape players to be more positive. Which brings us to the Honor system. Honor is a way for players to reward each other for good behavior. This is divvied up into four categories: Friendly, Helpful, Teamwork, and Honorable Opponent. At the end of a match, players can hand out points to those they deem worthy. These points are reflected on players’ profiles, but do not result in any in-game bonuses or rewards (though this may change in the future). All Honor does is show that you played nicely. 6 Ways Windows 8 Is More Secure Than Windows 7 HTG Explains: Why It’s Good That Your Computer’s RAM Is Full 10 Awesome Improvements For Desktop Users in Windows 8

• JustCode &ndash; Color Identifier Basics

  Color identifiers make it easier for developers to quickly read and understand the code on screen.  One of the many features provided by JustCode is the ability to colorize additional items that Visual Studio does not allow you to colorize by default.  The colorization of items such as methods, properties, events, variables, and method parameters can easily be tweaked to your specific needs. Enable / Disable Color Identifiers In the recent release, we turned this option on by default.  You can enable/disable code colorization by going to the JustCode menu in Visual Studio, selecting options, then selecting the general section in the left window.  When you scroll down on general setting you will see a check box that says Color Identifiers.  Check or uncheck this box to enable/disable code colorization.    Color identifiers option   Adjust Color Identifiers Adjusting the color identifiers in JustCode is done in the same place ...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors?

• Microsoft Dev Days &ndash; Johannesburg 2010

  - by MarkPearl

  So I am half way through dev days in Johannesburg. It has been quite an interesting day… Maybe it is me, but this year it hasn’t been as OMG as at previous conferences. A few things that stood out though… 1) This is the first time I have had to queue in a line to use the gents toilets before – yes, a true sign that we are at a typically male dominated industry event in this country – the men’s toilets were jam packed – the ladies if there were any there didn’t have a problem. 2) Bart De Smet presentation still rocks – I am a fan of Bart’s and once again his presentation was great. Something that I am going to look into in more depth which I think is a new feature in .Net is called Code Contracts. 3) I have got to get into Silverlight more… I have known this for a long time and have dabbled in it for a while, but Silverlight in my opinion will become the main platform for “hosting” applications. So… 3 things so far, hopefully I get some OMG’s from the rest of the day…

• JSON Support in Azure

  - by kaleidoscope

  Please find how we call JavaScript Object Notation in cloud applications. As we all know how client script is useful in web applications in terms of performance.           Same we can use JQuery in Asp.net using Cloud  computing which will  asynchronously pull any messages out of the table(cloud storage)  and display them in the     browser by invoking a method on a controller that returns JavaScript Object Notation (JSON) in a well-known shape. Syntax : Suppose we want to write a  JQuery function which return some notification while end user interact with our application so use following syntax : public JsonResult GetMessages() {      if (User.Identity.IsAuthenticated)      {     UserTextNotification[] userToasts =           toastRepository.GetNotifications(User.Identity.Name);          object[] data =          (from UserTextNotification toast in userToasts          select new { title = toast.Title ?? "Notification",          text = toast.MessageText }).ToArray();           return Json(data, JsonRequestBehavior.AllowGet);      }         else            return Json(null); } Above function is used to check authentication and display message if user is not exists in Table.

• Question aboud Headings For Professionals <H1>... <H9> in SEO & Browsercompatibility Differences

  - by Sam

  We all know the importance ans significance of Headings for Professional Webmasters. These were known for professional developers as <h1>Heading 1</h1> h2 ... h6. As a daring webdeveloper I lately needed more short headings for complex structured document and i thought what the hell and went ahead and used in css h1,h2,h3,h4,h5,h6{ } h7{ } h8{ } h9{ } My experiment turned out to pay back. But only in Firefox, Safari, Chrome etc, not in Internet Explorer 8. Q1. Who(&When) decided that All headings should go upto h6, and not h4 or h7? Q2. Why h7 -h9 work perfect in all major browsers, except IE8? Q3. What is the significance for Bing,Yahoo and Googld in terms of recognition or headings h1 ~ h9? obviously h1 is more important than 2, but do they differentiate between h5 and h6? or not anymore after h3?

• Any good reason open files in text mode?

  - by Tinctorius

  (Almost-)POSIX-compliant operating systems and Windows are known to distinguish between 'binary mode' and 'text mode' file I/O. While the former mode doesn't transform any data between the actual file or stream and the application, the latter 'translates' the contents to some standard format in a platform-specific manner: line endings are transparently translated to '\n' in C, and some platforms (CP/M, DOS and Windows) cut off a file when a byte with value 0x1A is found. These transformations seem a little useless to me. People share files between computers with different operating systems. Text mode would cause some data to be handled differently across some platforms, so when this matters, one would probably use binary mode instead. As an example: while Windows uses the sequence CR LF to end a line in text mode, UNIX text mode will not treat CR as part of the line ending sequence. Applications would have to filter that noise themselves. Older Mac versions only use CR in text mode as line endings, so neither UNIX nor Windows would understand its files. If this matters, a portable application would probably implement the parsing by itself instead of using text mode. Implementing newline interpretation in the parser might also remove some overhead of using text mode, as buffers would need to be rewritten (and possibly resized) before returning to the application, while this may be less efficient than when it would happen in the application instead. So, my question is: is there any good reason to still rely on the host OS to translate line endings and file truncation?

• Web Services and code lists

  - by 0x0me

  Our team heavily discuss the issues how to handle code list in a web service definition. The design goal is to describe a provider API to query a system using various values. Some of them are catalogs resp. code lists. A catalog or code list is a set of key value pairs. There are different systems (at least 3) maintaining possibly different code lists. Each system should implement the provider API, whereas each system might have different code list for the same business entity eg. think of colors. One system know [(1,'red'),(2,'green')] and another one knows [(1,'lightgreen'),(2,'darkgreen'),(3,'red')] etc. The access to the different provider API implementations will be encapsulated by a query service, but there is already one candidate which might use at least one provider API directly. The current options to design the API discussed are: use an abstract code list in the interface definition: the web service interface defines a well known set of code list which are expected to be used for querying and returning data. Each API provider implementation has to mapped the request and response values from those abstract codelist to the system specific one. let the query component handle the code list: the encapsulating query service knows the code list set of each provider API implementation and takes care of mapping the input and output to the system specific code lists of the queried system. do not use code lists in the query definition at all: Just query code lists by a plain string and let the provider API implementation figure out the right value. This might lead to a loose of information and possibly many false positives, due to the fact that the input string could not be canonical mapped to a code list value (eg. green - lightgreen or green - darkgreen or both) What are your experiences resp. solutions to such a problem? Could you give any recommendation?

• SharePoint 2010 in the cloud a.k.a. SharePoint Online

  - by Sahil Malik

  Ad:: SharePoint 2007 Training in .NET 3.5 technologies (more information). There are 3 ways to run SharePoint On premises, you buy the servers, and you run the servers. Hosted servers, where you don’t run the servers, but you let a hosting company run dedicated servers. Multi-tenant, like SharePoint online – this is what I am talking about in this blog post. Also known as SaaS (Software as a Service). The advantages of a cloud solution are undeniable. Availability, (SharePoint line offers a 99.9% uptime SLA) Reliability. Cost. Due to economies of scale, and no need to hire specialized dedicated staff. Scalability. Security. Flexibility – grow or shrink as you need to. If you are seriously considering SharePoint 2010 in the cloud, there are some things you need to know about SharePoint online. What will work - OOTB Customization, collaboration features etc. will work SharePoint Designer 2010 is supported, so no code workflows will work Visual Studio sandbox solutions, client object model will work. What won’t work - SharePoint 2010 online cloud environment supports only sandbox solutions. BCS, business connectivity services is not supported in SharePoint online. What you can do however is to host your services in Azure, and call them using Silverlight. Custom timer jobs will not work. Long story short, get used to Sandbox solutions – and the new way of programming. Sandbox solutions are pretty damn good. Most of the complaints I have heard around sandbox solutions being too restrictive, are uninformed mechanisms of doing things mired in the ways of 2002. .. or you could just live in 2002 too.

• Another big year for the ADF EMG at OOW12

  - by Chris Muir

  Oracle Open World 2012 has only just started, but in one way it's just finished!  All the ADF EMG's OOW content is over for another year! The unique highlight this year for me was the first ever ADF EMG social night held on Saturday, where I finally had the chance to meet so many ADF community members who I've known over the internet, but never met in person.  What?  You didn't get an invite?  Oh well, better luck next year ;-) Seriously our budget was limited, so in the happy-dictatorship sort of way I had to limit RSVPs to just 40 people.  Hopefully next year we can do something bigger and better for the wider community. Following directly on from the Saturday social night the ADF EMG ran a full day of sessions at the user group Sunday.  I wont go over the content again, but to say thank you very much to all our presenters and helpers, including Gert Poel, Pitier Gillis, Aino Andriessen, Simon Haslam, Ken Mizuta, Lucas Jellema and the FMW roadshow team, Ronald van Luttikhuizen, Guido Schmutz, Luc Bors, Aino Andriessen and Lonneke Dikmans. Also special thanks must go to Doug Cockroft and Bambi Price for their time and effort in organizing the ADF EMG room behind the scenes via the APOUC. To be blunt Doug and Bambi really do deserve serious thanks because they had to wear a lot of Oracle politics behind the scenes to get the rooms organized (oh, and deal with me fretting too! ;-). Finally thanks to all the members and OOW delegates for turning up and supporting the group on the day.  In the end the ADF EMG exists for you, and I hope you found it worthwhile. Onto 2013 (oh, and the rest of OOW12 ;-)

One of the features I simply love about it is virtual machines snapshots, its saves a state of a virtual machine and is able to restore it to its former glory if something you did went wrong without any problems and without consuming your all hard disk space. On my live systems I know how to create a 1:1 image of the file system but all the solutions I'v known will create a new image of the complete file system. Are there any programs / file systems that are capable of taking a snapshot of a current file system, save it on another location but instead of making a complete new image it creates incremental backups? To easy describe what I want, it should be as dd images of a file system, but instead of only a full backup it would also create incremental. I am not looking for clonezilla, etc. It should run within the system itself with no (or almost none) intervention from the user, but contain all the data of the file systems. I am also not looking for a duplicity backup your all system excluding some folders script + dd to save your mbr. I can do that myself, looking for extra finesse. I'm looking for something I can do before doing massive changes to a system and then if something when wrong or I burned my hard disk after spilling coffee on it I can just boot from a liveCD and restore a working snapshot to a hard disk. It does not need to be daily, it doesn't even need a schedule. Just run once in a while and let it its job and preferably RAW based not file copy based.

• How to Assure an Effective Data Model

  As a general rule in my opinion the effectiveness of a data model can be directly related to the accuracy and complexity of a project’s requirements. For example there is no need to work on very detailed data models when the details surrounding a specific data model have not been defined or even clarified. Developing data models when the clarity of project requirements is limited tends to introduce designed issues because the proper details to create an effective data model are not even known. One way to avoid this issue is to create data models that correspond to the complexity of the existing project requirements so that when requirements are updated then new data models can be created based any new discoveries regarding requirements on a fine grain level.  This allows for data models to be composed of general entities to be created initially when a project’s requirements are very vague and then the entities are refined as new and more substantial requirements are defined or redefined. This promotes communication amongst all stakeholders within a project as they go through the process of defining and finalizing project requirements.In addition, here are some general tips that can be applied to projects in regards to data modeling.Initially model all data generally and slowly reactor the data model as new requirements and business constraints are applied to a project.Ensure that data modelers have the proper tools and training they need to design a data model accurately.Create a common location for all project documents so that everyone will be able to review a project’s data models along with any other project documentation.All data models should follow a clear naming schema that tells readers the intended purpose for the data and how it is going to be applied within a project.

• Earmarks of a Professional PHP Programmer

  - by Scotty C.

  I'm a 19 year old student who really REALLY enjoys programming, and I'm hoping to glean from your years of experience here. At present, I'm studying PHP every chance I get, and have been for about 3 years, although I've never taken any formal classes. I'd love to some day be a programmer full time, and make a good career of it. My question to you is this: What do you consider to be the earmarks or traits of a professional programmer? Mainly in the field of PHP, but other, more generalized qualifications are also more than welcome, as I think PHP is more of a hobbyist language and may not be the language of choice in the eyes of potential employers. Please correct me if I'm wrong. Above all, I don't want to wast time on something that isn't worth while. I'm currently feeling pretty confident in my knowledge of PHP as a language, and I know that I could build just about anything I need and have it "work", but I feel sorely lacking in design concepts and code structure. I can even write object oriented code, but in my personal opinion, that isn't worth a hill of beans if it isn't organized well. For this reason, I bought Matt Zandstra's book "PHP Objects, Patterns, and Practice" and have been reading that a little every day. Anyway, I'm starting to digress a little here, so back to the original question. What advice would you give to an aspiring programmer who wants to make an impact in this field? Also, on a side note, I've been working on a project with a friend of mine that would give a fairly good idea of where I'm at coding wise. I'm gonna give a link, I don't want anyone to feel as though I'm pushing or spamming here, so don't click it if you don't want to. But if you are interested on giving some feedback there as well, you can see the code on github. I'm known as The Craw there. https://github.com/PureChat/PureChat--Beta-/tree/
