  • advice for a new software engineer/developer right out of college

    - by ranzy
    I just graduated recently from a 4-year university with a degree in Computer Science and thankfully got a job in Software Engineering. I'm working with C++ with a .NET framework if that's correct to say because that also confuses me. What I'm asking for is what tutorials/books are out there to learn C++ for Windows Programming I guess? I know how to program somewhat and I understand the concepts but when I look at the code it doesn't make sense to me. I know I just started so it's kind of expected but it's certainly quite different from college. Thanks!

  • Criteria strings, how many different criteria can be entered to retrieve specific data?

    - by Janet
    For our membership database we are currently using an old DOS program "Arclist". The program is old but the one feature we desperately need in a database program is to be able to enter multiple criteria at one time for more of a "one time" extraction of the data meeting all the various criteria entered in what I call a "criteria string". An example may be extracting only those records with zip codes matching (67893, 54235, 54323, 54201, 54302, 54303, 54301, 67894, 67895). Another set of criteria might be to omit records, not equal to, one type of criteria in one field and also extract records matching criteria in another field. So we would want records "not equal to" in one field, but whose information equals requested information in another field.

  • UNESCO, J-ISIS, and the JavaFX 2.2 WebView

    - by Geertjan
    J-ISIS, which is the newly developed Java version of the UNESCO generalized information storage and retrieval system for bibliographic information, continues to be under heavy development and code refactoring in its open source repository. Read more about J-ISIS and its NetBeans Platform basis here. Soon a new version will be available for testing and it would be cool to see the application in action at that time. Currently, it looks as follows, though note that the menu bar is under development and many menus you see there will be replaced or removed soon: About one aspect of the application, the browser, which you can see above, Jean-Claude Dauphin, its project lead, wrote me the following: The DJ-Native Swing JWebBrowser has been a nice solution for getting a Java Web Browser for most popular platforms. But the Java integration has always produced from time to time some strange behavior (like losing the focus on the other components after clicking on the Browser window, overlapping of windows, etc.), most probably because of mixing heavyweight and lightweight components and also because of our incompetency in solving the issues. Thus, recently we changed for the JavaFX 2.2 WebWiew. The integration with Java is fine and we have got rid of all the DJ-Native Swing problems. However, we have lost some features which were given for free with the native browsers such as downloading resources in different formats and opening them in the right application. This is a pretty cool step forward, i.e., the JavaFX integration. It also confirms for me something I've heard other people saying too: the JavaFX WebView component is a perfect low threshold entry point for Swing developers feeling their way into the world of JavaFX.

Does it seem an adventure? Well it is and I will tell you how I came to have this international experience. Dzien Dobry! My name is Wojciech Jurojc, I am Polish and I am currently a Business Development Consultant within Oracle, based in Prague. I joined Oracle on the 1st of August 2011. I graduated in 2010 and obtained 2 Masters Degrees in Political Science and Economics. I would like to tell you more about my past and how I joined Oracle. In 2005 I began studying at the Faculty of Political Sciences Gdansk University. In 2008, I obtained a Bachelors Degree. During these three years I had the opportunity to go to England twice, where I worked as a Bartender, first in Blackpool and then in Manchester. This allowed me to improve my language skills and become more confident. In the meantime, I joined the International Student Organization-AIESEC, where I was organized conferences and conducted student projects. Also I met a mass of interesting people from around the world. After graduation in 2008, I was able to get an Internship within a big company in Poland. I worked there as an Intern in the Purchase Department. That was my first adventure within a corporate environment. I learnt a lot about purchasing processes and negotiations. In September 2008, I started studying two Masters Faculties: Political Science and Economics. It was very difficult, but it was not impossible. Over the next two years of studying I was able to go on a three month internship to India where I worked as a Marketing Assistant in an NGO. I was travelling around northern India and did presentations to the academic community about green energy and environmental projects. I had the opportunity to visit Nepal and walked in the Himalayas. That was a huge experience as well as a cultural shock. It taught me how to deal with many problems and to appreciate what I have. At the end of 2009 I was working as a Marketing Assistant for a Leasing company, where I learnt useful sales knowledge and improved my objection handling skills. In July 2010, I graduated with a double Masters and found a job in Thailand as Sales Representative in an IT company. I worked in Thailand until the end of January 2011. Besides that, I was working in an International company with interesting people and I had the opportunity to travel around Thailand and visit Cambodia. After this adventure I started looking for jobs in Europe where I could further develop my sales skills. I found Oracle and I don’t regret this decision which I made. I am currently working in Prague in an international Hardware team and I know that is not the end of my adventures. At this moment, I am working in a team of 12 members. Ten of them are based in Prague and 2 others are based in Russia. We come from different countries such as: Czech Republic, Russia, Ukraine, Turkey, Slovakia and Kazakhstan. I am working on the Polish market, cooperating with our Hardware customers and partners. What do I enjoy the most about my job? I enjoy every challenge that I face in my daily activities as there are always new experiences for me and new things that I learn. As part of Oracle, I gain international exposure and therefore more career opportunities to explore. I have planned my next step for the career path I dream of and I am currently working on it. I recommend you check our Career Page if you’re looking for an international career. If you want to find out more about our job opportunities, follow us on https://campus.oracle.com .

  • Computer cables explained

    - by Robert English
    I've noticed lately that places to learn about both power supply cables and also peripherals and fans aren't that easy to find. There's very little information available that gives detailed explanations of what cables are used inside a computer. What I found was very dated and often lacked detailed explanations. For someone planning out their first build it would be great way for this to be explained all in one place, like here! Important things to know about cables and connections in a computer? What are their names? Where do they connect to and why? What typical Voltages do they output? Changing Voltages for Overclocking? Please refernce PSU cables(Full modular, Modular and Non-Modular,24-pin, 20+4-pin etc), SATA(I, II, III), Molex etc. EDIT: Forgot to mention any information about PSU rails would also be appreciated :)

  • What are the hard and fast rules for Cache Control?

    - by Metalshark
    Confession: sites I maintain have different rules for Cache Control mostly based on the default configuration of the server followed up with recommendations from the Page Speed & Y-Slow Firefox plug-ins and the Network Resources view in Google's Speed Tracer. Cache-Control is set to private/public depending on what they say to do, ETag's/Last-Modified headers are only tinkered with if Y-Slow suggests there is something wrong and Vary-Accept-Encoding seems necessary when manually gziping files for Amazon CloudFront. When reading through the material on the different options and what they do there seems to be conflicting information, rules for broken proxies and cargo cult configurations. Any of the official information provided by the analysis tools mentioned above is quite inaccessible as it deals with each topic individually instead of as a unified strategy (so there is no cross-referencing of techniques). For example, it seems to make no sense that the speed analysis tools rate a site with ETag's the same as a site without them if they are meant to help with caching. What are the hard and fast rules for a platform agnostic Cache Control strategy? EDIT: A link through Jeff Atwood's article explains Caching in superb depth. For the record though here are the hard and fast rules: If the file is Compressed using GZIP, etc - use "cache-control: private" as a proxy may return the compressed version to a client that does not support it (the browser cache will hold files marked this way though). Also remember to include a "Vary: Accept-Encoding" to say that it is compressible. Use Last-Modified in conjunction with ETag - belt and braces usage provides both validators, whilst ETag is based on file contents instead of modification time alone, using both covers all bases. NOTE: AOL's PageTest has a carte blanche approach against ETags for some reason. If you are using Apache on more than one server to host the same content then remove the implicitly declared inode from ETags by excluding it from the FileETag directive (i.e. "FileETag MTime Size") unless you are genuinely using the same live filesystem. Use "cache-control: public" wherever you can - this means that proxy servers (and the browser cache) will return your content even if the rest of the page needs HTTP authentication, etc.

  • In MVC , DAO should be called from Controller or Model

    - by tito
    I have seen various arguments against the DAO being called from the Controller class directly and also the DAO from the Model class.Infact I personally feel that if we are following the MVC pattern , the controller should not coupled with the DAO , but the Model class should invoke the DAO from within and controller should invoke the model class.Why because , we can decouple the model class apart from a webapplication and expose the functionalities for various ways like for a REST service to use our model class. If we write the DAO invocation in the controller , it would not be possible for a REST service to reuse the functionality right ? I have summarized both the approaches below. Approach #1 public class CustomerController extends HttpServlet { proctected void doPost(....) { Customer customer = new Customer("xxxxx","23",1); new CustomerDAO().save(customer); } } Approach #2 public class CustomerController extends HttpServlet { proctected void doPost(....) { Customer customer = new Customer("xxxxx","23",1); customer.save(customer); } } public class Customer { ........... private void save(Customer customer){ new CustomerDAO().save(customer); } } Note- Here is what a definition of Model is : Model: The model manages the behavior and data of the application domain, responds to requests for information about its state (usually from the view), and responds to instructions to change state (usually from the controller). In event-driven systems, the model notifies observers (usually views) when the information changes so that they can react. I would need an expert opinion on this because I find many using #1 or #2 , So which one is it ?

I was looking to generate a passive income that would not take too much of an initiall learning curve. And it occurs to me that teaching/writing books/ on High School math/Physics/English is something I can do without a lot of prepwork. I am in Toronto . what are the average income opportunities for something like this? Where should I start looking?

  • How do you debug why Windows is slow?

    - by aaron
    I've got Vista Biz and when my machine chugs I think it is because of paging, but I never know how to verify this. Procexp doesn't seem to provide useful information because it appears that nothing is going on when the chugs happen. perfmon seems like it has the counters I need, but I'm never sure what counters I should add to cover the information I want. For perfmon, I prefer numbers that are percents, so I can gauge load. Here are the counters I have up, but they don't always seem to correlate to chugs: - % disk time (logical) - page faults/sec (an indicator of lots of paging activity) - processor/%priviliged time

  • Application Scope v's Static - Not Quite the same

    - by Duncan Mills
    An interesting question came up today which, innocent as it sounded, needed a second or two to consider. What's the difference between storing say a Map of reference information as a Static as opposed to storing the same map as an application scoped variable in JSF?  From the perspective of the web application itself there seems to be no functional difference, in both cases, the information is confined to the current JVM and potentially visible to your app code (note that Application Scope is not magically propagated across a cluster, you would need a separate instance on each VM). To my mind the primary consideration here is a matter of leakage. A static will be (potentially) visible to everything running within the same VM (OK this depends on which class-loader was used but let's keep this simple), and this includes your model code and indeed other web applications running in the same container. An Application Scoped object, in JSF terms, is much more ring-fenced and is only visible to the Web app itself, not other web apps running on the same server and not directly to the business model layer if that is running in the same VM. So given that I'm a big fan of coding applications to say what I mean, then using Application Scope appeals because it explicitly states how I expect the data to be used and a provides a more explicit statement about visibility and indeed dependency as I'd generally explicitly inject it where it is needed.  Alternative viewpoints / thoughts are, as ever, welcomed...

  • How can I disable logging in Tomcat 7?

    - by WilliamMayor
    I have a Tomcat 7 server running in a VM that has very little disk space (20G). Over the course of a few days Tomcat will fill the space with logging info (usually about 15G before it runs out). I've tried turning down the log level (from INFO to SEVERE) in the logging.properties file, I've also tried sending the log info to /dev/null. It doesn't seem to work as I still get a full log directory after no time at all. Can I put a file size limit on the log files? Is something overriding the properties I'm setting? Where can I find this information? My Google Fu just returns information about logging from within an application using JULI.

  • The Start of a Blog

    - by dbradley
    So, here's my new blog up and running, who am I and what am I planning to write here?First off - here's a little about me:I'm a recent graduate from university (coming up to a year ago since I finished) studying Software Engineering on a four year course where the third year was an industrial placement. During the industrial placement I went to work for a company called Adfero in a "Technical Consultant" role as well as a junior "Information Systems Developer". Once I completed my placement I went back to complete my final year but also continued in my developer role 2/3 days a week with the company.Working part time while at uni always seems like a great idea until you get half way through the year. For me the problem was not so much having a lack of time, but rather a lack of interest in the course content having got a chance at working on real projects in a live environment. Most people who have been graduated a little while also find this - when looking back at uni work, it seem to be much more trivial from a problem solving point of view which I found to be true and I found key to uni work to actually be your ability to prove though how you talk about something that you comprehensively understand the basics.After completing uni I then returned full time to Adfero purely in the developer role which is where I've now been for almost a year and have now also taken on the title of "Information Systems Architect" where I'm working on some of the more high level design problems within the products.What I'm wanting to share on this blog is some of the interesting things I've learnt myself over the last year, the things they don't teach you in uni and pretty much anything else I find interesting! My personal favorite areas are text indexing, search and particularly good software engineering design - good design combined with good code makes the first step towards a well-written, maintainable piece of software.Hopefully I'll also be able to share a few of the products I've worked on, the mistake I've made and the software problems I've inherited from previous developers and had to heavily re-factor.

  • About to graduate from good school without any progamming skills

    - by newprint
    Not sure if it is good place to ask this question, but found this section to be suitable. I am about to graduate from a good school (in the US) with Computer Science degree, having good grades and high GPA. I have no freaking clue how to write a good program, how to properly test it... nada, zero. We were never been taught how to write software. Ye, sure the Comp. Architecture class is important, and I can tell you a lot about how MIPS processor works, and I can tell you about Binary Trees and Red-Black Trees and running time of operations in Big Oh, but it has nothing to do with programming in "real" life. For god sake, none of my classmates know how to use STLs or write templated code! To be honest, I found that many of my classes to be waste of time. What should I do ? How to step into real life and learn how to program ?

  • How seriously would an employer take a job application from an applicant studying at the Open University [closed]

    - by user866190
    I ask the question because I am considering applying to a traditional bricks and mortar university to do mathematics, computer science or software engineering. However I am in my late twenties and have a young family so I am seriously considering going down the Open University route and working in the software development industry at the same time. If I do attend Open University, I will definitely study Mathematics. I fell in love with PHP and the common web technologies a few years back and it has slowly progressed into learning C++, Java and also Python. If I spent the next year increasing my knowledge of those languages whilst studying at the Open University, would an employee consider a self taught programmer who is 20% of the way through a Bsc in Mathematics?

  • Oracle E-Business Suite is Helping to Save Lives at the National Marrow Donor Program

    - by Di Seghposs
    To improve the management of its life-saving operations, the National Marrow Donor Program recently modernized its financial and procurement operations by upgrading to Oracle E-Business Suite 12.1.   As the global leader in bone marrow and umbilical cord blood transplants, the NMDP manages a complex ecosystem of donor, patient, hospital, and biological data. “Maintaining accurate data and having an efficient matching process is essential, particularly as our global database of bone marrow patients grows and donor lists expand,” says Bruce Schmaltz, director of finance/controller. “We rely on the Oracle E-Business Suite to ensure our procurement and financial management processes meet the highest standards, enabling our growing non-profit to work swiftly and efficiently to help improve and save lives.” As the non-profit organization and its registry grew larger, NMDP needed a modern platform to store and integrate its financial information and complicated procurement process. It selected Oracle E-Business Suite for its ability to fit seamlessly into NMDP’s enterprise architecture. NMDP initially implemented Oracle E-Business Suite release 12 by leveraging Oracle Business Accelerators, which are rapid implementation tools and templates that help reduce implementation time and costs. With Oracle Financial Management and Oracle Procurement, NMDP has streamlined back-office processes and integrated its procure-to-pay business processes by leveraging industry leading accounts payable, accounts receivable, and general ledger modules. NMDP is currently rolling out Oracle Hyperion Performance Management applications and plans to implement Oracle Order Management and Oracle Advanced Pricing by the end of 2012. Read more details about NMDP’s modernization efforts.  For more updates on Oracle Financial Management Solutions, view our November 2012 Oracle Information InDepth Financial Management newsletter. Subscribe Now.
