• New Exam Score Report Process Coming Soon

  - by Paul Sorensen

  Hi Everyone! I want to give you a preview of a process change that will be coming in the next few weeks. We will soon announce a change in the way that Oracle certification candidates receive their exam scores and score reports (after they take an exam). Once the change occurs you will need to have an Oracle Web Account (in order to access your exam score). This is the account that is used to log into the Oracle website for things such as OTN access, software downloads and other Oracle services. If you already have an Oracle Web Account then you are already in good shape! If you do not have an Oracle Web Account the you should create one now (in preparation for this change)!  Look for additional announcements and detailed information in the coming weeks. Thanks,

• Time To Consider Getting Your Oracle Certification?

  - by Paul Sorensen

  Hi Everyone,I recently read an interesting study from Global Knowledge titled: 2010 IT Skills and Salary Report which contains a lot of great information related to IT worker trends including roles, required skills, demographics, salaries and more. I had to dig a little bit, but the report indicates that certification is valued by the majority of managers and those become certified, which underscores the results of our own surveys that show how certification is valued by IT workers, their employers and their customers.Additionally, if you look a little closer you will also find average salaries for those who are Oracle certified. Their salary figures are impressive and are among the top salaries of the certifications listed.If you have ever considered becoming certified or are in the process of becoming certified, I encourage you to look at the Global Knowledge study. With an ever-increasing suite of Oracle certifications available to you, there may be something within our certification offerings that will help you increase your skills, build your career, and gain additional credibility.Thank you,QUICK LINKSGlobal Knowledge 2010 IT Skills and Salary ReportOracle Certification 2009 Salary SurveyOracle Certification web site

  The role of Java developer may just be better than ever. An excellent article in Java Magazine discusses the availability of web-based tools that help development teams more effectively manage their projects and modules. If you are a Java developer you should definitely read this article. I especially like the Expert Opinions scattered throughout the article. These highlight real-world usage of the latest and greatest development tools.  As you consider steps to move your career forward, consider Java certification. Oracle has over 15 unique Java certification credentials available. The process of becoming certified in Java and preparing for your exams will require you to study, learn and practice (code). All of this activity will help you sharpen your skills and increase your working knowledge of Java - making you a better developer and more valuable member of your team. You can use the Certification Finder on the Oracle certification homepage to find a Java certification that is right for you. Thanks!

• Opportunities in Cloud Computing

  - by Paul Sorensen

  A recent article from CIO Journal indicates that there is an extreme labor shortage (in certain technology areas) that is is leading to upward pressure on wages for IT Workers. This represents a great opportunity for those with certain skill-sets, among which include Java (Oracle certification is mentioned specifically). The article points out that a key driver of the labor shortage is the expansion of cloud computing. Cloud computing is set up to make life extremely simple for end-users, but the model pushes the complexity to back-end systems which are sophisticated, enterprise-level computing stacks (Oracle has an extensive set of cloud computing solutions). These complex systems require very highly-skilled IT professionals (the best-of-the-best) to successfully develop, implement, administer and maintain them. What this mean for you is that there is opportunity for those who have the appropriate skills at the appropriate levels. If you want to be a part of this opportunity you should do a self-assessment of your own skill-sets and experience. Based upon your results you can decide where it would be most appropriate to spend your time and resources for the highest return on your investment. By expanding and sharpening your skills and by gaining greater experience you will be better prepared to take advantage of career opportunities (like this) that come along periodically. As you evaluate your needs remember that Oracle University has a tremendous selection of high-quality eduction offerings (including training and certification) that can you help move your career forward. Thanks and best of luck!

• Branding Changes for Java EE6

  - by Paul Sorensen

  Hi Everyone, As we move the Java EE6 exams from beta to production, you may notice that we have made a slight change in the branding. Instead of being branded Oracle Certified Professional (OCP), these new credentials are now branded Oracle Certified Expert (OCE). One area where we use the Expert brand is for credentials where the technology is advanced or broader than the path based credential requires. Some are high-end add-on certifications, and others have significant additional technological breadth. In these cases, the Expert brand is an indication that someone is tested in more advanced or in-depth skills - beyond the traditional path-based certification. A few examples are RAC Expert for DBAs, or SQL Expert - also for DBAs. Because (1) all of the Java EE6 credentials require that candidates become certified first in Java SE6, and (2) many people earn more than one Java EE credential, we felt that the Expert branding would be more appropriate. Thanks,

• DDD Modeling questions : student, classroom, seats and a favorite seat for a student.

  - by Erik Ashepa

  Hi, i'm not sure how to model this relationship... A classroom contains many seats, every student studies in a classroom and have a favorite seat within it. The way i see it, i have two aggregate roots: classroom and student, seats a are entities aggregatged by classroom... And for a student to have a fovorite seat, it must hold a reference to it (seat isn't an aggregate root). Any suggestions? Thanks in advance, Erik.

• Tool to check if web server is following HTTP standard?

  - by Erik Öjebo

  I'm writing a simple HTTP server which should play nicely with most clients, but is only meant to implement a subset of HTTP 1.1. During development it would be nice to be able to validate that the generated HTTP reponses are HTTP 1.1 compliant. Is there a tool that can do something along those lines? Thanks /Erik

• How to use Python list comprehension (or such) for retrieving rows when using MySQLdb?

  - by Erik Nygren

  Hey all, I use MySQLdb a lot when dealing with my webserver. I often find myself repeating the lines: row = cursor.fetchone() while row: do_processing(row) row = cursor.fetchone() Somehow this strikes me as somewhat un-pythonic. Is there a better, one-line way to accomplish the same thing, along the lines of inline assignment in C: while (row = do_fetch()) { do_processing(row); } I've tried figuring out the syntax using list comprehensions, but I can't seem to figure it out. Any recommendations? Thanks, Erik

• Youtube Downloader

  Hi, A time ago I had a script who got the flv-file from a specified youtube-video, which now is broken due to changes at their website. I am wondering if Youtube may have an API to download the flv-file, where can I find it in that case? Have anyone build an own script, may someone wanna help be building it? Is there any scripts in any other languages such as shell/bash that works? :) Best regards, Erik Persson

• setting enablesReturnKeyAutomatically on UISearchBar

  - by Erik Carlson

  Hi There, I'm writing for iphone OS 3.1.3. I want the search button in the keyboard from my UISearchBar to have the search button enabled all the time. If this was any old UITextField (not a search bar) the property would be enablesReturnKeyAutomatically. I have tried setting this using the example given at http://discussions.apple.com/thread.jspa?messageID=8457910 which suggests: UITextField *searchTextField ; searchTextField = [[searchBar subviews]objectAtIndex:0]; searchTextField.enablesReturnKeyAutomatically = NO ; Should work. unfortunately it crashes: 2010-05-20 08:36:18.284 ARemote[5929:207] *** -[UISearchBarBackground setEnablesReturnKeyAutomatically:]: unrecognized selector sent to instance 0x3b31980 2010-05-20 08:36:18.284 ARemote[5929:207] *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '*** -[UISearchBarBackground setEnablesReturnKeyAutomatically:]: unrecognized selector sent to instance 0x3b31980' I have also tried ((UITextField *)[(NSArray *)[searchBar subviews] objectAtIndex:0]).enablesReturnKeyAutomatically = NO;</code> Which gives similar results. Any ideas? Cheers Erik

• Random Gui errors using C# Mono on OSX

  - by Erik Karlsson

  Hello. Im developing a app in c# (winforms), which uses mono to run on osx. It contains some dynamic controls, for example a custom groupbox which contains some labels and textboxes, a button etc. these boxes can both be added and removed dynamically. Problem arises both when they are created, and removed, or even when a messagebox is shown. What happens is that sometimes on rendering white boxes appears, or some labels are not drawn correctly. And sometimes when a messagebox appears, it first opens up like 5 dummies which are just blank, and which you cant close. Am i doing something wrong, should i sleep the gui thread a bit after each creation, or should i invalidate stuff on my own? Or should i try GTK#? Many thanks on input on this, Erik

• Change present working directory of a calling shell from a ruby script

  - by Erik Kastman

  I'm writing a simple ruby sandbox command-line utility to copy and unzip directories from a remote filesystem to a local scratch directory in order to unzip them and let users edit the files. I'm using Dir.mktmpdir as the default scratch directory, which gives a really ugly path (for example: /var/folders/zz/zzzivhrRnAmviuee+++1vE+++yo/-Tmp-/d20100311-70034-abz5zj) I'd like the last action of the copy-and-unzip script to cd the calling shell into the new scratch directory so people can access it easily, but I can't figure out how to change the PWD of the calling shell. One possibility is to have the utility print out the new path to stdout and then run the script as part of a subshell (i.e. cd $(sandbox my_dir) ), but I want to print out progress on the copy-and-unzipping since it can take up to 10 minutes, so this won't work. Should I just have it go to a pre-determined, easy-to-find scratch directory? Does anyone have a better suggestion? Thanks in advance for your help. -Erik

• ReadOnlyCollection or IEnumerable for exposing member collections?

  - by Erik Öjebo

  Is there any reason to expose an internal collection as a ReadOnlyCollection rather than an IEnumerable if the calling code only iterates over the collection? class Bar { private ICollection<Foo> foos; // Which one is to be preferred? public IEnumerable<Foo> Foos { ... } public ReadOnlyCollection<Foo> Foos { ... } } // Calling code: foreach (var f in bar.Foos) DoSomething(f); As I see it IEnumerable is a subset of the interface of ReadOnlyCollection and it does not allow the user to modify the collection. So if the IEnumberable interface is enough then that is the one to use. Is that a proper way of reasoning about it or am I missing something? Thanks /Erik

• Unit Testing & Fake Repository implementation with cascading CRUD operations

  - by Erik Ashepa

  Hi, i'm having trouble writing integration tests which use a fake repository, For example : Suppose I have a classroom entity, which aggregates students... var classroom = new Classroom(); classroom.Students.Add(new Student("Adam")); _fakeRepository.Save(classroom); _fakeRepostiory.GetAll<Student>().Where((student) => student.Name == "Adam")); // This query will return null... When using my real implementation for repository (NHibernate based), the above code works (because the save operation would cascade to the student added at the previous line), Do you know of any fake repository implementation which support this behaviour? Ideas on how to implement one myself? Or do you have any other suggestions which could help me avoid this issue? Thanks in advance, Erik.

• PHP - CSRF - How to make it works in all tabs?

  - by Erik Persson

  Hi there, I have readed about how to prevent CSRF-attacks in the last days. I am going to update the token in every pageload, save the token in the session and make a check when submitting a form. But what if the user has, lets say 3 tabs open with my website, and I just store the last token in the session? This will overwrite the token with another token, and some post-action is going to fail. Do I need to store all tokens in the session, or is there a better solution to get this working? Best regards, Erik Persson

• SetEnvIf regex for setting Content-Disposition HTTP header

  - by Erik Sorensen

  I am attempting to use the IHS 7.0/apache 2.2 SetEnvIf directive to set the filename of a downloaded file based on a url parameter. I think I am pretty close, however if there is a space (encoded or otherwise) in the filename - it fails. example url: http://site.com/path/to/filename.ext/file-title=Nice File Name.ext?file-type=foo apache config: SetEnvIf Request_URI "^.*file-title\=(.*)\??.*$" FILENAME=$1 Header unset "Content-Disposition" Header add "Content-Disposition" "attachment; filename=%{FILENAME}e" UnsetEnv FILENAME An application will specify what is now showing up as "Nice File Title.ext" in the example. This all works great if there are no spaces, however - if there is a space the filename to download will just show up as "Nice". There may or may not be a second set of parameters in the query string (?file-type, etc)

• how to pre-create directories on linux for file storage

  - by Erik Sorensen

  Hi - looking for a way to pre-create directories on linux to be used to store a large number of files. We will be generating file ids using a GUID - I need to keep a copy of these files on a linux web server. I plan on using subdirectories to split up the files (it's ext3)... so for example, the filename 055c102b-62fb-4671-a3c7-68b9515ec53e.swf would live in /data/files/0/5/5/055c102b-62fb-4671-a3c7-68b9515ec53e.swf (taking the first 3 characters as directory names) My question is - how to create the /data/files/?/?/?/ directories ahead of time? Where ? could be a-z or 0-9
