  • Vacations on Rodrigues 2014

    And now something completely different compared to the usual technical or community related articles here on this blog. Yes, this time I'm writing some lines on my (and my family's) activities during our long weekend stay on Rodrigues. So, please bear with me, it's eventually a bit more personal... Grab a soda, some popcorn and a cosy place to continue to read. var googleAlbumLink = "https://plus.google.com/photos/117698191428446859536/albums/6047895311458281985"; //optional----------------------- var mySlideWidth = 580; var mySlideHeight = 340; var mySlideDelay = 7000; //delay in milliseconds Special promotions during school holidays Originally, our children started to ask more frequently about going on the plane again. Obviously, after their aunty from Germany was around during May, they were really eager to travel again. So, we decided that it might be a great opportunity to book some vacations during their school holidays. And just in time the local hotels and hotel groups started to advertise their special promotions for citizens and residents. After collecting multiple brochures over several days, we got attracted by various hotel packages on Rodrigues - most interestingly the expenses for the stay and flight ticket were less compared to other resorts here on the main island. As we have been to Rodrigues already back in 2008, we followed up on this idea and got in touch with a couple travel agencies. Well, I have to report that you should be really careful about the promotions from some of them. We had a very negative experience with Shamal Travel Agency in Quatre Bornes regarding their adverts and the actual price levels and age definition for children. Please, stay away from them if you are interested in transparent cost and services. Anyway, after some arrangements with two other close families we managed to confirm our stay at the Cotton Bay Hotel in Rodrigues. Given the fact that we already stayed there, and the hotel has been renovated recently, and it is under new management all looked very promising and relaxed for our vacation. Counting the days... As we already booked in July our children were counting down the days. And it got more interesting as soon as they were on school holidays finally. Well, the day arrived and waking them up at 2:30 hrs wasn't a problem after all. Quite the opposite it was fascinating for us parents to watch them waiting for the transport and later on during the airport transfer. Despite the early hours both didn't fall asleep and it was all so exciting. We are taking the plane! Well organised by the Cotton Bay Hotel Honestly, it was a breeze and a smooth ride during our stay at the hotel. From the airport transfer, the cleanliness of our bungalow, the organisation of our day trips, and the SPA - all very well and enjoyable. The children had great fun, and although it was a bit too windy to plunge into the pool they had a lot of fun with other activities on the beach and at the Kid's Club. Oh, and we had our private petting zoo with cows, sheep and goats just close to the terrace. Some of us went to check out the SPA facilities and I have to admit that the services regarding Hammam and Sauna are better than at some other hotels in Mauritius. I don't know after how many months or years I was once again enjoying a very hot sauna. Little draw-back but nothing to worry about... There is no cold water or at least ice cubes to cool down the body, but hey there was a nice breeze coming over the hills. Some day trips to mention Based on a friend's recommendation we walked to a "restaurant" called Chez Solange & Robert. Hahaha, restaurant is widely stretched in this case, as we enjoyed a great BBQ with fresh lobster, whole fish, and pieces of chicken breast in an open cottage. Just some wooden structure covered with dried palm leaves on the roof - island feeling pure! The other day we went to the Giant Tortoise & Cave Reserve Francois Leguat to observe the giant Aldabra turtles and to visit the Grande Caverne. The biggest limestone cave on the island. Compared to our last visit this was a novelty after checking out the Caverne Partate. The formations of stalactites and stalagmites are very impressive and imaginative. Our guide had lots of funny terms and despite the low light conditions the kids had a great time wandering around on the narrow wooden paths and stairs. And last but not least, we decided to check out the Tyrodrig zip lines... Everyone was allowed to join the trip through the air, and our little ones stayed close to our field guides. But finally went on their own on the very last traversal. Puuuh, it was astounishing to glide over the valley, and for sure something to repeat next time. Impressions of our vacation on Rodrigues 2014   Next stay has been discussed already Oh yes, Rodrigues baby! We are going to come again! Tentative dates have been discussed already and now it's up to us to earn enough our next holiday on that wonderful remote piece of paradise. Eventually, a little bit longer than this time. We'll see...

  • Victor Grazi, Java Champion!

    - by Tori Wieldt
    Congratulations to Victor Grazi, who has been made a Java Champion! He was nominated by his peers and selected as a Java Champion for his experience as a developer, and his work in the Java and Open Source communities. Grazi is a Java evangelist and serves on the Executive Committee of the Java Community Process, representing Credit Suisse - the first non-technology vendor on the JCP. He also arranges the NY Java SIG meetings at Credit Suisse's New York campus each month, and he says it has been a valuable networking opportunity. He also is the spec lead for JSR 354, the Java Money and Currency API. Grazi has been building real time financial systems in Java since JDK version 1.02! In 1996, the internet was just starting to happen, Grazi started a dot com called Supermarkets to Go, that provided an on-line shopping presence to supermarkets and grocers. Grazi wrote most of the code, which was a great opportunity for him to learn Java and UI development, as well as database management. Next, he went to work at Bank of NY building a trading system. He studied for Java certification, and he noted that getting his certification was a game changer because it helped him started to learn the nuances of the Java language. He has held other development positions, "You may have noticed that you don't get as much junk mail from Citibank as you used to - that is thanks to one of my projects!" he told us. Grazi joined Credit Suisse in 2005 and is currently Vice President on the central architecture team. Grazi is proud of his open source project, Java Concurrent Animated, a series of animations that visualize the functionality of the components in the java.util.concurrent library. "It has afforded me the opportunity to speak around the globe" and because of it, has discovered that he really enjoys doing public presentations. He is a fine addition to the Java Champions program. The Java Champions are an exclusive group of passionate Java technology and community leaders who are community-nominated and selected under a project sponsored by Oracle. Nominees are named and selected through a peer review process. Java Champions get the opportunity to provide feedback, ideas, and direction that will help Oracle grow the Java Platform. This interchange may be in the form of technical discussions and/or community-building activities with Oracle's Java Development and Developer Program teams.

  • Outstanding Silverlight User Group Meeting last night

    - by Dave Campbell
    We had a great Silverlight User Group Meeting in Phoenix last night! Before I go any farther I want to say thanks again to David Silverlight and Kim Schmidt for coming to talk to us! And not to forget Victor Gaudioso over the wire :) David, Kim, and Victor talked to us about the Silverlight User Group Starter Kit they are working on with an extended stellar list of talented developers. Don't bypass looking at this by thinking it's only for a User Group... this is a solid community-supported full-up application using MVVM and Ria Services that you could take and modify for your own use. Take a look at the list of developers. Chances are you know some of them... send them an email of thanks for all the hard work over the last year! David and Kim discussed the architecture and code, demonstrating features as they went. Then Victor came in through the application itself on a high-intensity live webcast from his home in California. The audience of about 15 seemed focused and interested which says a lot about the subject and presentation. Tim Heuer came bearing some gifts (swag) ... a hard-copy of Josh Smith's Advanced MVVM , and couple cheaply upgradeable copies of VS2008 Pro that were snatched up very quickly. We also gave away a few copies of Windows 7 Ultimate 64-bit, some Arc mice, and some Office 2007 disks... so I don't think anyone left empty-handed. Personal thanks from me go out to Mike Palermo and Tim Heuer for the surprise they had waiting for me that's been over Twitter, and to Victor for only mentioning it at least 3 times in a 5-minute webcast. Thanks for a great evening, and I look forward to seeing all of you in a couple weeks at MIX10!

    My laptop is an old HP Compaq NX6110. The wireless switch is not working, and I can`t also enable wireless from connexion manager. I connected to to the Internet with Ubuntu using wired LAN, and I downloaded windows wireless drivers, Wi-Fi radar application, and additional drivers. I also updated to Ubuntu 11.10 but still no luck. I guess I need some terminal commands. Any ideas are welcome. Thank you for the attention victor.

  • Ubuntu 12.04 64 bit doesn't work on a win7 with check point full disk encryption

    - by Victor Rodriguez
    I installed Ubuntu 12.04 64 bit with the Wubi installer on a Windows 7 with Check Point Full Disk Encryption. The Wubi Installer runs without any trouble selecting the compatibility mode with WinXP and as Administrator. The problem is that after the installation is complete and the reboot done, when you restart the system, there's no option to start Ubuntu instead of Windows. I recently installed Ubuntu on other Win7 machines without any problem. But those laptops don't have the Check Point Full Disk Encryption. And when you restart the system you have the option to start in Ubuntu. If somebody has resolved this issue please share...!!! Regards! Víctor

  • Handling EJB/JPA exceptions in a “beautiful” way

    - by Rodrigues, Raphael
    In order to handle JPA exceptions, there are some ways already detailed in lots of blogs. Here, I intend to show one of them, which I consider kind of “beauty”. My use case has a unique constraint, when the User try to create a duplicate value in database. The JPA throws a java.sql.SQLIntegrityConstraintViolationException, and I have to catch it and replace the message. In fact, ADF Business Components framework already has a beautiful solution for this very well documented here . However, for EJB/JPA there's no similar approach. In my case, what I had to do was: 1. Create a custom Error Handler Class in DataBindings file; a. Here is how you accomplish it. 2. Override the reportException method and check if the type of exception exists on property file a. If yes, I change the message and rethrows the exception b. If not, go on the execution The main goal of this approach is whether a new or unhandled Exception was raised, the job is, only create a single entry in bundle property file. Here are pictures step by step: 1. CustomExceptionHandler.java 2. Databindings.cpx 3. Bundle file 4. jspx: 5. Stacktrace: Give your opinion, what did you think about that?

  • How to create a simple adf dashboard application with EJB 3.0

    - by Rodrigues, Raphael
    In this month's Oracle Magazine, Frank Nimphius wrote a very good article about an Oracle ADF Faces dashboard application to support persistent user personalization. You can read this entire article clicking here. The idea in this article is to extend the dashboard application. My idea here is to create a similar dashboard application, but instead ADF BC model layer, I'm intending to use EJB3.0. There are just a one small trick here and I'll show you. I'm using the HR usual oracle schema. The steps are: 1. Create a ADF Fusion Application with EJB as a layer model 2. Generate the entities from table (I'm using Department and Employees only) 3. Create a new Session Bean. I called it: HRSessionEJB 4. Create a new method like that: public List getAllDepartmentsHavingEmployees(){ JpaEntityManager jpaEntityManager = (JpaEntityManager)em.getDelegate(); Query query = jpaEntityManager.createNamedQuery("Departments.allDepartmentsHavingEmployees"); JavaBeanResult.setQueryResultClass(query, AggregatedDepartment.class); return query.getResultList(); } 5. In the Departments entity, create a new native query annotation: @Entity @NamedQueries( { @NamedQuery(name = "Departments.findAll", query = "select o from Departments o") }) @NamedNativeQueries({ @NamedNativeQuery(name="Departments.allDepartmentsHavingEmployees", query = "select e.department_id, d.department_name , sum(e.salary), avg(e.salary) , max(e.salary), min(e.salary) from departments d , employees e where d.department_id = e.department_id group by e.department_id, d.department_name")}) public class Departments implements Serializable {...} 6. Create a new POJO called AggregatedDepartment: package oramag.sample.dashboard.model; import java.io.Serializable; import java.math.BigDecimal; public class AggregatedDepartment implements Serializable{ @SuppressWarnings("compatibility:5167698678781240729") private static final long serialVersionUID = 1L; private BigDecimal departmentId; private String departmentName; private BigDecimal sum; private BigDecimal avg; private BigDecimal max; private BigDecimal min; public AggregatedDepartment() { super(); } public AggregatedDepartment(BigDecimal departmentId, String departmentName, BigDecimal sum, BigDecimal avg, BigDecimal max, BigDecimal min) { super(); this.departmentId = departmentId; this.departmentName = departmentName; this.sum = sum; this.avg = avg; this.max = max; this.min = min; } public void setDepartmentId(BigDecimal departmentId) { this.departmentId = departmentId; } public BigDecimal getDepartmentId() { return departmentId; } public void setDepartmentName(String departmentName) { this.departmentName = departmentName; } public String getDepartmentName() { return departmentName; } public void setSum(BigDecimal sum) { this.sum = sum; } public BigDecimal getSum() { return sum; } public void setAvg(BigDecimal avg) { this.avg = avg; } public BigDecimal getAvg() { return avg; } public void setMax(BigDecimal max) { this.max = max; } public BigDecimal getMax() { return max; } public void setMin(BigDecimal min) { this.min = min; } public BigDecimal getMin() { return min; } } 7. Create the util java class called JavaBeanResult. The function of this class is to configure a native SQL query to return POJOs in a single line of code using the utility class.

  • Running ADF Essentials in Tomcat

    - by Rodrigues, Raphael
    Oracle released a few days ago ADF Essentials, which is a free version of its Oracle ADF Framework. Oracle ADF Essentials can run on the Glassfish Application Server, well explained by Shay here  . Glassfish is also certified to run ADF Essentials Application. However, It could be possible to run ADF Essentials Applications in a Java EE Container. So, I’ll describe the steps to run the ADF Faces Rich Client demo application into a Tomcat 7. Before we start, you should download the files: • Apache Tomcat 7 : http://tomcat.apache.org/download-70.cgi • Oracle ADF Essentials 11.1.2.3 : http://www.oracle.com/technetwork/developer-tools/adf/downloads/index.html • Oracle ADF Faces Components Demo 11.1.2.3: http://www.oracle.com/technetwork/developer-tools/adf/downloads/index.html Steps: 1. Extract your tomcat 7. In my case, I choose D:\ apache-tomcat-7.0.29 2. Extract ADF Essentials zip file inside the %TOMCAT_HOME%\lib 3. Put the rcf-dvt-demo.war file inside the %TOMCAT_HOME%\webapps 4. Open the file %TOMCAT_HOME%\bin\catalina.bat (or .sh if you’re in linux environment) and add in the end of the line ‘set JAVA_OPTS=%JAVA_OPTS% %LOGGING_CONFIG%’ this -Xms1024m -Xmx1024m If you don’t do this, probably when you start you’ll see a OutOfMemory error. 5. Here is the little trick, tomcat does not come with jsf jar’s, so you have to put there. So, I went to the Oracle Jdeveloper 11.1.2 instalation and search for this files: • jsf-api.jar • jsf-impl.jar • glassfish.jstl_1.2.0.1.jar 6. You’re ready to start tomcat in %TOMCAT_HOME%\bin\startup.bat If everything is fine, you will be able to open your favourite browser and type http://localhost:8080/rcf-dvt-demo/faces/index.jspx

  • Why are two indicator-network versions being worked on?

    - by Daniel Rodrigues
    Some months ago, on the road to Ubuntu Maverick, a new system indicator, network (with connman as a backend), started to be developed. The plan was to get it into UNE and release it with no notifcation area. Unfortunately it didn't make it into the final version. However, continued efforts are still being made to improve it, and I'm getting regular updates. From a blueprint from the last UDS, I read that the plan was to ship no notification area and only indicators. For that, it was defined that nm-applet (backend: NetworkManager) should be ported to the appindicator library. Today I discovered that those efforts are going on and a initial version is available for testing, available from Matt Trudel PPA (Natty only). So, my questions is, to whoever has the necessary info: wouldn't it be easier to join efforts and concentrate the work in just one version (probably NetworkManager backend, as that's the official plan), instead of breaking those efforts apart and hampering both testing and developing? Both indicators are being developed by Canonical engineers, and that really doesn't make much sense. So, any Canonical engineer willing to clarify this?

  • Is there any practical use for the empty type in Common Lisp?

    - by Pedro Rodrigues
    The Common Lisp spec states that nil is the name of the empty type, but I've never found any situation in Common Lisp where I felt like the empty type was useful/necessary. Is it there just for completeness sake (and removing it wouldn't cause any harm to anyone)? Or is there really some practical use for the empty type in Common Lisp? If yes, then I would prefer an answer with code example. For example, in Haskell the empty type can be used when binding foreign data structures, to make sure that no one tries to create values of that type without using the data structure's foreign interface (although in this case, the type is not really empty).

  • Choice the project pattern, advice for this case

    I have a project in MVC4 entity framework, and have to adapt it to possible updates on the dlls and system do not stop work. I'm using portable Areas, but have difficulty creating 5 modules and about 5 functionality for each modules with fully functioning independently as a dll and database. 1- Reflection DLLs, the system works "on the fly". (I cant do it on mvc4 at moment). 2- Portables Areas (I need to do one area for each modules*functionality 5*5 Areas).

  • My Interview with Microsoft

    - by Victor Hurdugaci
    This post is for those who want to apply or have already applied (but not finished the interview) for a Microsoft Job. The recruitment process is quite similar for everyone and consists of a few steps. Application E-Mail Interview Phone Interview On Site Interview I will tell you my story and how I went through the four phases. 1. Application My blog's title (Ex Nihilo Nihil Fit) means "Nothing Comes Out of Nothing". You can't get a job at Microsoft by not doing anything - this is true for anything else. The first step you need to complete is the application process. For this, many options are available. You can... ... apply online on Microsoft's Careers website as I did ... send your CV to different e-mail addresses (there are some dedicated e-mails for different positions) ... apply through some 3rd party organization (job shop, campus recruitment, job agency, etc) On MS Careers you just have to post your CV and choose the job you want. That's all! No recommendation letter, no cover letter, no nothing. Of course, not every CV passes the selection process. Here are some tips for improving your resume (worked for me): Don't write it just before applying! Write a draft version, wait a few days and then review it. This way you will find a lot of mistakes and stupid things you wrote initially. If you review it immediately after writing, your mind will not be criticism oriented and will just ignore mistakes. Repeat the write-wait-review process as many times as necessary, until you find that the review revealed no mistakes. After you did the final review and the CV is bullet-proof, ask others to review it. They will definitely find inconsistencies and mistakes and this will make you feel stupid. This is good because will open your eyes will make you go into an 'I want to improve' mode. You'll try to correct everything. After you come up with a modified version go again through steps 1 and 2. Repeat this as many times as necessary. [Special thanks to Lucian Sasu, Nadia Comanici, Andrei Ciobanu, Monica Balan and Lavinia Tanase for reviewing my CV!] Make it short and give only relevant facts. Initially, I come up with a 5 pages CV because I wrote every single technology with which I worked. There were a lot irrelevant things, I wrote Windows Workflow Foundation just because I played with it for a few days. I added extensive descriptions for every project, made a personal details section (name, birth date, address, etc) of 1/2 page. Others suggested to cut everything that was not necessary. You don't need to give extensive descriptions, just add a few words. For example, I wrote "VS Image Visualizer - Visual Studio 2008 debug visualizer for images" and added a link to the project's page - you submit formatted andcan embed links. Add something that makes it different. I don't know if this makes a difference, but I added some lines to separate items just like in the picture below. Definitely Microsoft gets thousands of CVs per day. You need something special. Don't lie! Tell exactly what you did and what is the proficiency level of your skills. For example, don't write "Advanced" for UML if you don't know the difference between composition and aggregation. Be realistic and don't under/over estimate yourself. Use the spell chick. Make sure everything is written in correct English and there are no grammar/spelling mistakes. Noddy likes a WC with grammar mi takes. You mght fail just because of that. Once you completed your CV, choose the job that suits best your needs, apply and wait... The waiting is a problem because all these big companies like Microsoft, Google, Mozilla, Apple, etc. will contact you only if they find something interesting in your application. If you're not suitable, then no rejection is sent. I applied for an Intern Software Development Engineer position at Microsoft Redmond. I cannot apply for a full time position because I want to finish the master program on time, in the next summer - an internship is just what I need. 2. E-Mail Interview January 20, 2010. Two months since I submitted the CV. I wasn't hoping anymore that MS will contact me, when I got an e-mail titled: "Victor Hurdugaci ES DK" from Holly Peterson saying: Read more >>

  • best ftp program (paid - not free)

    - by Victor Kimura
    Just would like some feedback on the best ftp program (not free). The requirements I'm looking for is: - secure ftp - for use on mac, linux, windows - backup utility with scheduler - for use on more than one computer (multi-license) I'm using wsftp from 2007 right now but it's only good for windows. It's license is only good for one computer. And after some vista updates it's making some strange noises. I tried to turn off the noise (via control panel) and it's still making that noise and I turned off the sound within wsftp too. I like the program but I think it's time to look for a new one. Thank you, Victor

  • What's better way to build NSPredicate with to-many deep relationships?

    - by Victor
    Hello, I have three entities: EntityA, EntityB and EntityC connected with to-many relationships. See schema for details: For getting all instance of EntityA which depend from EntityB.name I use the predicate like this: NSPredicate *predicate = [NSPredicate predicateWithFormat:@"ANY EntityB.name like 'SomeName'"]; What should be predicate for getting all instance of EntityA which depend from EntityC.name? I tried query like @"ANY EntityB.entitiesC.name like 'SomeName'" but get exception "multiple to-many keys not allowed here". Best regards, Victor

  • Doing a large number of upserts as fast as possible

    - by Jason Swett
    My app (which uses MySQL) is doing a large number of subsequent upserts. Right now my SQL looks like this: INSERT IGNORE INTO customer (name,customer_number,social_security_number,phone) VALUES ('VICTOR H KINDELL','123','123','123') INSERT IGNORE INTO customer (name,customer_number,social_security_number,phone) VALUES ('VICTOR H KINDELL','123','123','123') INSERT IGNORE INTO customer (name,customer_number,social_security_number,phone) VALUES ('VICTOR H KINDELL OR','123','123','123') INSERT IGNORE INTO customer (name,customer_number,social_security_number,phone) VALUES ('TRACY L WALTER PERSONAL REP FOR','123','123','123') INSERT IGNORE INTO customer (name,customer_number,social_security_number,phone) VALUES ('TRACY L WALTER PERSONAL REP FOR','123','123','123') So far I've found INSERT IGNORE to be the fastest way to achieve upserts. Selecting a record to see if it exists and then either updating it or inserting a new one is too slow. Even this is not as fast as I'd like because I need to do a separate statement for each record. Sometimes I'll have around 50,000 of these statements in a row. Is there a way to take care of all of these in just one statement, without deleting any existing records?

    Jeff Victor: Solaris Virtualization Book Jeff Victor with an update on the status of the book, "Oracle Solaris 10 System Virtualization Essentials." (tags: sun solaris virtualization) Mitch Denny: Architecture vs. Design It's an old post but it still resonates: "In the consumer electronics business, some people are actually hired to go through a system and remove components until it stops working – they do this to remove the cost before they go into mass production. We need more of this in the software business." -- Mitch Denny (tags: architecture design development) @vambenepe: Enterprise application integration patterns for IT management: a blast from the past or from the future? "In a recent blog post, Don Ferguson (CTO at CA) describes CA Catalyst, a major architectural overall which “applies enterprise application integration patterns to the problem of integrating IT management systems”. Reading this was fascinating to me. Not because the content was some kind of revelation, but exactly for the opposite reason. Because it is so familiar." -- William Vambenepe (tags: otn oracle eai)

  • Mysql table comment increase length. Is this a bug?

    - by Victor Kimura
    Hi, I read the mysql table lengths questions on stackoverflow on here: questions/391323/table-comment-length-in-mysql questions/2473934/how-to-increase-mysql-table-comments-length The first link suggests that it can be done and the second suggests it cannot. I don't know why there is this limitation as the comments are very useful. Imagine if there was a limit of 60 characters for your programs. I wrote about this on my site and have some snapshots to the phpmyadmin and Dbforge MySQL IDEs: http://mysql.tutorialref.com/mysql-table-comment-length-limit.html Is there a way to change this in phpmyadmin or perhaps even on the CLI? There is a bug commit report from MySQL on this particular problem (follow the link from the stackoverflow (first link). It seems to state that the length problem is fixed. I have MySQL 5.1.42. Thank you, Victor

  • How to detect non-graceful disconnect of Twisted on Linux?

    - by Victor Lin
    I wrote a server based on Twisted, and I encountered a problem, some of the clients are disconnected not gracefully. For example, the user pulls out the network cable. For a while, the client on Windows is disconnected (the connectionLost is called, and it is also written in Twisted). And on the Linux server side, my connectionLost of twisted is never triggered. Even it try to writes data to client, but the connection is lost. Why Twisted can't detect those non-graceful disconnection (even write data to client) on Linux? How to makes Twisted detect non-graceful disconnections? Because the feature Twisted can't detect non-graceful, I have lots of zombie user on my server. Thanks. Victor Lin.
