• ASP.Net MVC: "Random" URLs getting generated by URL.Action

  - by Daniel Magliola

  I have 2 very similar routes, just because i'm trying to generate two different URLs for the same resource (same Controller/Action), and both are very similar. These are the routes definitions: routes.MapRoute("Post2.Mp3", "sites/{siteSlug}/post/{brand}/aconstant-{slug}.mp3", new { controller = "Posts", action = "Mp3" }, new { siteSlug = @"[A-Za-z0-9-_]+", slug = @"[^(aconstant\-)][A-Za-z0-9-_]+", brand = @"[A-Za-z0-9-_]+" }); routes.MapRoute("Post.Mp3", "sites/{siteSlug}/post/{slug}.mp3", new { controller = "Posts", action = "Mp3" }, new { siteSlug = @"[A-Za-z0-9-_]+", slug = @"[A-Za-z0-9-_]+" }); "brand" is going to be my site name, which is the same as "aconstant" in those routes. Now, if I try this: Url.Action("ShowMp3", "Posts", new { siteSlug = post.Site.Slug, slug = post.Slug, origin = "origfeedwithaudio", brand = "aconstant" }) sometimes I get the URL I expect: /sites/site-Name/post/aconstant/aconstant-post-Name.mp3 but sometimes, I get this: /sites/site-Name/post/post-Name.mp3?brand=aconstant By sometimes, I mean that different sets of "slugs" give me one or the other. I haven't seen the same set of slugs give me different URLs. I haven't found any reasonable rule for when i'm getting one or the other, it seems random. What is going on here? How can I be getting different URLs based on esentially the same arguments? Thanks! Daniel

• Synchronizing files between Linux servers, through FTP

  - by Daniel Magliola

  I have the following configuration of servers: 1 central linux server, a VPS 8 satellite linux servers, "crappy shared hostings" I have a bunch of files that I need to have in all servers. Right now i'm copying them everywhere manually, but I want to be able to copy them to the central server, and then have a scheduled process that runs every now and then and synchronizes them (only outwardly, no need to try to find "new" files in the satellite servers). There are a couple of catches though: I can't have any custom software in the satellite servers, or do strange command line things that'll auto connect to them and send the files directly. I know this is the way these kinds of things are normally done, but the satellite servers are crappy shared hosting ones where I have absolutely no control over anything. I need to send the files over FTP I also need to have, in my central server, a list of the files that are available in each of the satellite servers, to make sure they are ready before I send traffic to them. If I were to do this manually, the steps would be: get the list of files in a satellite server compare to my own, and send the files that are missing get the list of files again, and store it in my central database. I'd like to know what tools are out there that can alleviate as much of this as possible, first the syncing, and then the "getting the list of files available in the other server". I'm going to be doing everything from PHP, not sure if there are good tools to "use FTP from PHP", which i'm pretty sure i'll have to do for step 3 at least. Thanks in advance for any ideas! Daniel

• Finding usage of jQuery UI in a big ugly codebase

  - by Daniel Magliola

  I've recently inherited the maintenance of a big, ugly codebase for a production website. Poke your eyes out ugly. And though it's big, it's mostly PHP code, it doesn't have much JS, besides a few "ajaxy" things in the UI. Our main current problem is that the site is just too heavy. Homepage weighs in at 1.6 Mb currently, so I'm trying to clean some stuff out. One of the main wasters is that every single page includes the jQuery UI library, but I don't think it's used at all. It's definitely not being used in the homepage and in most pages, so I want to only include the where necessary. I'm not really experienced with jQuery, i'm more of a Prototype guy, so I'm wondering. Is there anything I could search for that'd let me know where jQuery UI is being used? What i'm looking for is "common strings", component names, etc For example, if this was scriptaculous, i'd look for things like "Draggable", "Effect", etc. Any suggestions for jQuery UI? (Of course, if you can think of a more robust way of removing the tag from pages that don't use it without breaking everything, I'd love to hear about it) Thanks!! Daniel

• java - coding errors causing endless loop

• Passing filtering functions to Where() in LINQ-to-SQL

  - by Daniel

  I'm trying to write a set of filtering functions that can be chained together to progressively filter a data set. What's tricky about this is that I want to be able to define the filters in a different context from that in which they'll be used. I've gotten as far as being able to pass a very basic function to the Where() clause in a LINQ statement: filters file: Func<item, bool> returnTrue = (i) => true; repository file: public IQueryable<item> getItems() { return DataContext.Items.Where(returnTrue); } This works. However, as soon as I try to use more complicated logic, the trouble begins: filters file: Func<item, bool> isAssignedToUser = (i) => i.assignedUserId == userId; repository file: public IQueryable<item> getItemsAssignedToUser(int userId) { return DataContext.Items.Where(isAssignedToUser); } This won't even build because userId isn't in the same scope as isAssignedToUser(). I've also tried declaring a function that takes the userId as a parameter: Func<item, int, bool> isAssignedToUser = (i, userId) => i.assignedUserId == userId; The problem with this is that it doesn't fit the function signature that Where() is expecting: Func<item, bool> There must be a way to do this, but I'm at a loss for how. I don't feel like I'm explaining this very well, but hopefully you get the gist. Thanks, Daniel

• topic-comment naming of functions/methods

  - by Daniel

  I was looking at American Sign Language the other day... and I noticed that the construction of the language was topic-comment. As in "Weather is good". That got me to thinking about why we name methods/functions in the manner of: function getName() { ... } function setName(v) { ... } If we think about naming in a topic-comment function, the function names would be function nameGet() { ... } function nameSet() { ... } This might be better for a class had multiple purposes. IE: class events { function ListAdd(); function ListDelete(); function ListGet(); function EventAdd(); function EventDelete(); function EventGet(); } This way the functions are grouped by "topic". Where as the former naming, functions are grouped Action-Noun, but are sorted by Noun. I thought this was an interesting POV, what do other people think about naming functions/methods Topic-Comment? Obviously, mixing naming conventions up in the same project would be weird, but overall? -daniel

• Weird MySQL behavior, seems like a SQL bug

  - by Daniel Magliola

  I'm getting a very strange behavior in MySQL, which looks like some kind of weird bug. I know it's common to blame the tried and tested tool for one's mistakes, but I've been going around this for a while. I have 2 tables, I, with 2797 records, and C, with 1429. C references I. I want to delete all records in I that are not used by C, so i'm doing: select * from i where id not in (select id_i from c); That returns 0 records, which, given the record counts in each table, is physically impossible. I'm also pretty sure that the query is right, since it's the same type of query i've been using for the last 2 hours to clean up other tables with orphaned records. To make things even weirder... select * from i where id in (select id_i from c); DOES work, and brings me the 1297 records that I do NOT want to delete. So, IN works, but NOT IN doesn't. Even worse: select * from i where id not in ( select i.id from i inner join c ON i.id = c.id_i ); That DOES work, although it should be equivalent to the first query (i'm just trying mad stuff at this point). Alas, I can't use this query to delete, because I'm using the same table i'm deleting from in the subquery. I'm assuming something in my database is corrupt at this point. In case it matters, these are all MyISAM tables without any foreign keys, whatsoever, and I've run the same queries in my dev machine and in the production server with the same result, so whatever corruption there might be survived a mysqldump / source cycle, which sounds awfully strange. Any ideas on what could be going wrong, or, even more importantly, how I can fix/work around this? Thanks! Daniel

• Plan Operator Tuesday round-up

  - by Rob Farley

  Eighteen posts for T-SQL Tuesday #43 this month, discussing Plan Operators. I put them together and made the following clickable plan. It’s 1000px wide, so I hope you have a monitor wide enough. Let me explain this plan for you (people’s names are the links to the articles on their blogs – the same links as in the plan above). It was clearly a SELECT statement. Wayne Sheffield (@dbawayne) wrote about that, so we start with a SELECT physical operator, leveraging the logical operator Wayne Sheffield. The SELECT operator calls the Paul White operator, discussed by Jason Brimhall (@sqlrnnr) in his post. The Paul White operator is quite remarkable, and can consume three streams of data. Let’s look at those streams. The first pulls data from a Table Scan – Boris Hristov (@borishristov)’s post – using parallel threads (Bradley Ball – @sqlballs) that pull the data eagerly through a Table Spool (Oliver Asmus – @oliverasmus). A scalar operation is also performed on it, thanks to Jeffrey Verheul (@devjef)’s Compute Scalar operator. The second stream of data applies Evil (I figured that must mean a procedural TVF, but could’ve been anything), courtesy of Jason Strate (@stratesql). It performs this Evil on the merging of parallel streams (Steve Jones – @way0utwest), which suck data out of a Switch (Paul White – @sql_kiwi). This Switch operator is consuming data from up to four lookups, thanks to Kalen Delaney (@sqlqueen), Rick Krueger (@dataogre), Mickey Stuewe (@sqlmickey) and Kathi Kellenberger (@auntkathi). Unfortunately Kathi’s name is a bit long and has been truncated, just like in real plans. The last stream performs a join of two others via a Nested Loop (Matan Yungman – @matanyungman). One pulls data from a Spool (my post – @rob_farley) populated from a Table Scan (Jon Morisi). The other applies a catchall operator (the catchall is because Tamera Clark (@tameraclark) didn’t specify any particular operator, and a catchall is what gets shown when SSMS doesn’t know what to show. Surprisingly, it’s showing the yellow one, which is about cursors. Hopefully that’s not what Tamera planned, but anyway...) to the output from an Index Seek operator (Sebastian Meine – @sqlity). Lastly, I think everyone put in 110% effort, so that’s what all the operators cost. That didn’t leave anything for me, unfortunately, but that’s okay. Also, because he decided to use the Paul White operator, Jason Brimhall gets 0%, and his 110% was given to Paul’s Switch operator post. I hope you’ve enjoyed this T-SQL Tuesday, and have learned something extra about Plan Operators. Keep your eye out for next month’s one by watching the Twitter Hashtag #tsql2sday, and why not contribute a post to the party? Big thanks to Adam Machanic as usual for starting all this. @rob_farley

• Consolidating Oracle E-Business Suite R12 on Oracle's SPARC SuperCluster

  - by Giri Mandalika

  An Optimized Solution for Oracle E-Business Suite (EBS) R12 12.1.3 is now available on oracle.com.     The Oracle Optimized Solution for Oracle E-Business Suite This solution was centered around the engineered system, SPARC SuperCluster T4-4. Check the business and technical white papers along with a bunch of relevant useful resources online at the above optimized solution page for EBS. What is an Optimized Solution? Oracle's Optimized Solutions are designed, tested and fully documented architectures that are tuned for optimal performance and availability. Optimized solutions are NOT pre-packaged, fully tuned, ready-to-install software bundles that can be downloaded and installed. An optimized solution is usually a well documented architecture that was thoroughly tested on a target platform. The technical white paper details the deployed application architecture along with various observations from installing the application on target platform to its behavior and performance in highly available and scalable configurations. Oracle E-Business Suite R12 Use Case Multiple E-Business Suite R12 12.1.3 application modules were tested in this optimized solution -- Financials (online - oracle forms & web requests), Order Management (online - oracle forms & web req uests) and HRMS (online - web requests & payroll batch). The solution will be updated with additional application modules, when they are available. Oracle Solaris Cluster is responsible for the high availability portion of the solution. Performance Data For the sake of completeness, test results were also documented in the optimized solution white paper. Those test results are mainly for educational purposes only. They give good sense of application behavior under the circumstances the application was tested. Since the major focus of the optimized solution is around highly available and scalable configurations, the application was configured to me et those criteria. Hence the documented test results are not directly comparable to any other E-Business Suite performance test results published by any vendor including Oracle. Such an attempt may lead to skewed, incorrect conclusions. Questions & Requests Feel free to direct your questions to the author of the white papers. If you are a potential customer who would like to test a specific E-Business Suite application module on any non-engineered syste m such as SPARC T4-X or engineered system such as SPARC SuperCluster, contact Oracle Solution Center.

• How can I convince IE to honor my explicit instructions to make a table column X pixels wide? [migrated]

  - by AnthonyWJones

  Please consider this small but complete chunk of HTML: <!DOCTYPE html > <html> <head> <title>Test</title> <style type="text/css"> span {overflow:hidden; white-space:nowrap; } td {overflow:hidden; text-overflow:ellipsis} </style> </head> <body> <table cellspacing="0" > <tbody> <tr> <td nowrap="nowrap" style="max-width:30px; width:30px; white-space:nowrap; "><span>column 1</span></td> <td nowrap="nowrap" style="max-width:30px; width:30px; white-space:nowrap; "><span>column 2</span></td> <td nowrap="nowrap" style="max-width:30px; width:30px; white-space:nowrap; "><span>column 3</span></td> </tr> </tbody> </table> </body> </html> If you render the above in Chrome you'll see the effect I'm looking for. However render it in IE8 or 9 the width and/or max-width is ignored. So my question is how do get IE to simply let me specify the width of a cell explicitly? BTW, I've tried various combinations of table-layout:fixed and using colgroup with cols and all sorts, nothing I've tried convinces IE to what I'm clearly asking it to explicitly do? If I had any hair before starting this I wouldn't have any left by now.

• Adding A Custom Dropdown in RCDC for Forefront Identity Manager 2010

  - by Daniel Lackey

  My latest exploration has been FIM 2010 for Identity Management. The following is a post of how to add a custom dropdown for the FIM Portal. I have decided to document this as I cannot find documentation on how to do this anywhere else. I hope that it finds useful to others.   For starters, this was to me not an easy task to figure out. I really would like to know why it is so cumbersome to do something that seems like a lot of people would need to do, but that’s for another day J   The dropdown I wanted to add was for ‘Account Status’ which would display if the account is ‘Enabled’ or ‘Disabled’ in the data source Active Directory. This option would also allow helpdesk users or admins to administer the userAccountControl attribute in AD from the FIM Portal interface.   The first thing I had to do was create the attribute itself. This is done by going to Administration à Schema Management from the FIM 2010 portal. Once here, you click on All Attributes. What is listed here are all attributes and their associated Resource Types in FIM. To create the ‘AccountStatus’ attribute, click on New. As shown below, enter ‘AccountStatus’ with no spaces for the System Name and ‘Account Status’ for the Display Name. The Data Type is going to be ‘Indexed String’. Click Next.           Leave everything on the Localization tab default and click Next.   On the Validation tab as shown below, we will enter the regex expression ^(Enabled|Disabled)?$ with our two desired string values ‘Enabled’ and ‘Disabled’. Click on Finish and then and Submit to complete adding the attribute.       The next step involves associating the attribute with a resource type. This is called ‘Binding’ the attribute. From the Schema Management page, click on All Bindings. From the page that comes up, click on New. As shown below, enter ‘User’ for the Resource Type and ‘Account Status’ for the Attribute Type. This is essentially binding the Account Status attribute to the ‘User’ Resource Type. Click Next.    On the ‘Attribute Override’ tab, type in ‘Account Status’ for the Display Name field. Click Next.   On the ‘Localization’ tab, click Next.   On the ‘Validation’ tab, enter the regex expression ^(Enabled|Disabled)?$ we entered previously for the attribute. Click Finish and then Submit to complete.   Now that the Attribute and the Binding are complete, you have to give users permission to see the attribute on the User Edit page. Go to Administration à Management Policy Rules. Look for the rule named Administration: Administrators can read and update Users and click on it. Once it opens, click on the ‘Target Resources’ tab and look at the section named Resource Attributes. Type in at the end the ‘Account Status’ attribute and check it with the validator. Once done click on OK to save the changes.         Lastly, we need to add the actual dropdown control to the RCDC (Resource Control Display Configuration) for User Editing. Go to Administration à Resource Control Display Configuration. From here navigate until you find the RCDC named Configuration for User Editing RCDC and click on it. The following is what you will see:       First step is to export the Configuration Data file. Click on the Export configuration link and save the file to your desktop of other folder.   Find the file you just exported and open the file in your XML editor of choice. I use notepad but anything will work. Since we are adding a dropdown control, first find another control in the existing file that is already a dropdown in FIM. I used EmployeeType as my example. Copy the control from the beginning tag named <my:Control… to the ending tag </my:Control>. Now take what you copied and paste it in whatever location you desire within the form between two other controls. I chose to place the ‘Account Status’ field after the ‘Account Name’ field. After you paste the control you will need to modify so it looks like this:       Notice where you specify what attribute you are dealing with where it has AccountStatus in the XML. Once you are complete with modifying this, save the file and make sure it is a .xml file.   Now go back to the Configuration for User Editing screen and look at the section named ‘Configuration Data’. Click the ‘Browse’ button and find the XML file you just modified and choose it. Click OK on the bottom of the window and you are done!   Now when you click on a user’s name in the FIM Portal, you should see the newly added dropdown box as below:       Later I will post more about this drop down, specifically on how to automate actually ‘Disabling’ the account in the data source through the FIM Workflows and MAs.   <my:Control my:Name="AccountStatus" my:TypeName="UocDropDownList" my:Caption="{Binding Source=schema, Path=AccountStatus.DisplayName}" my:Description="{Binding Source=schema, Path=AccountStatus.Description}" my:RightsLevel="{Binding Source=rights, Path=AccountStatus}"> <my:Properties> <my:Property my:Name="ValuePath" my:Value="Value"/> <my:Property my:Name="CaptionPath" my:Value="Caption"/> <my:Property my:Name="HintPath" my:Value="Hint"/> <my:Property my:Name="ItemSource" my:Value="{Binding Source=schema, Path=AccountStatus.LocalizedAllowedValues}"/> <my:Property my:Name="SelectedValue" my:Value="{Binding Source=object, Path=AccountStatus, Mode=TwoWay}"/> </my:Properties> </my:Control>

• Example WLST Script to Obtain JDBC and JTA MBean Values

  - by Daniel Mortimer

  Introduction Following on from the blog entry "Get an Offline or Online WebLogic Domain Summary Using WLST!", I have had a request to create a smaller example which only collects a selection of JDBC (System Resource) and JTA configuration and runtime MBeans values. So, here it is. Download Sample Script You can grab the sample script by clicking here. Instructions to Run: 1. After download, extract the zip to the machine hosting the WebLogic environment. You should have three directories along with a readme.txt output Sample_Output scripts 2. In the scripts directory, find the start wrapper script startWLSTJDBCSummarizer.sh (Unix) or startWLSTJDBCSummarizer.cmd (MS Windows). Open the appropriate file in an editor and change the environment variable settings to suit your system. Example - startWLSTDomainSummarizer.cmd set WL_HOME=D:\product\FMW11g\wlserver_10.3 set DOMAIN_HOME=D:\product\FMW11g\user_projects\domains\MyDomain set WLST_OUTPUT_PATH=D:\WLSTDomainSummarizer\output\ set WLST_OUTPUT_FILE=WLST_JDBC_Summary_Via_MBeans.html call "%WL_HOME%\common\bin\wlst.cmd" WLS_JDBC_Summary_Online.py Note: The WLST_OUTPUT_PATH directory value must have a trailing slash. If there is no trailing slash, the script will error and not continue.  3. Run the shell / command line wrapper script. It should launch WLST and kick off "WLS_JDBC_Summary_Online.py". This will hit you with some prompts e.g. Is your domain Admin Server up and running and do you have the connection details? (Y /N ): Y Enter connection URL to Admin Server e.g t3://mymachine.acme.com:7001 : t3://localhost:7001 Enter weblogic username: weblogic Enter weblogic username password (function prompt 1): welcome1 (Note: the value typed in for password will not be echoed back to the console). 4. If the scripts run successfully, you should get a HTML summary in the specified output directory. See example screenshots below: Screenshot 1 - JDBC System Resource Tab Page  Screenshot 2 - JTA Tab Page 5. For the HTML to render correctly, ensure the .js and .css files provided (review the output directory created by the zip file extraction) are accessible. For example, to view the HTML locally (without using a web server), place the HTML output, jquery-ui.js, spry.js and wlstsummarizer.css in the same directory. Disclaimer This is a sample script. I have tested it against WebLogic Server 10.3.6 domains on MS Windows and Unix.  I cannot guarantee that the script will run error free or produce the expected output on your system. If you have any feedback add a comment to the blog. I will endeavour to fix any problems with my WLST code.

• Objective-C As A First OOP Language?

  - by Daniel Scocco

  I am just finishing the second semester of my CS degree. So far I learned C, all the fundamental algorithms and data structures (e.g., searching, sorting, linked lists, heaps, hash tables, trees, graphs, etc). Next year we'll start with OOP, using either Java or C++. Recently I got some ideas for some iPhone apps and got itchy to start working on them. However I heard some bad things about Objectice-C in the past, so I am wondering if learning it as my first OOP language could be a problem. Not to mention that I think it will be hard to find books/online courses that teach basic OOP concepts using Objective-C to illustrate the concepts (as opposed to books using Java or C++, which are plenty), so this could be another problem. In summary: should I start learning Objective-C and OOP concepts right now by my own, or wait one more semester until I learn Java/C++ at university and then jump into Objective-C? Update: For those interested in getting started with OOP via Objective-C I just found some nice tutorials inside Apple's Developer Library - http://developer.apple.com/library/mac/#documentation/Cocoa/Conceptual/OOP_ObjC/Introduction/Introduction.html

• How do I install 32-bit perl-tgicl 2.1.1?

• Improving the state of the art in API documentation sites

  - by Daniel Cazzulino

  Go straight to the site if you want: http://nudoq.org. You can then come back and continue reading :) Compare some of the most popular NuGet packages API documentation sites: Json.NET EntityFramework NLog Autofac You see the pattern? Huge navigation tree views, static content with no comments/community content, very hard (if not impossible) to search/filter, etc. These are the product of automated tools that have been developed years ago, in a time where CHM help files were common and even expected from libraries. Nowadays, most of the top packages in NuGet.org don’t even provide an online documentation site at all: it’s such a hassle for such a crappy user experience in the end! Good news is that it doesn’t have to be that way. Introducing NuDoq A lot has changed since those early days of .NET. We now have NuGet packages and the awesome channel that is ...Read full article

• Guide to Downloading Oracle Fusion Middleware 11g Products

  - by Daniel Mortimer

  IntroductionThe idea of writing a blog about downloading software seems a bit strange .. right? After all, surely just give me the web download link and away I go!? Unfortunately, life is not so simple if you are a DBA or Systems Administrator tasked with staging Oracle Fusion Middleware 11g products for your chosen business technology stack. Here are the challenges: Oracle Fusion Middleware is not a single product, it is a family of products - a media pack with many many "disks" - which ones do I pick? Are the products I pick certified / supported on my chosen platform? Which download site do I use? I need to be on the latest and greatest - how do I get hold of the latest product patch set? The purpose of this blog is to give you a roadmap to get you through these challenges. Oracle Fusion Middleware 11g - A Product SuiteThe first thing to appreciate is that Oracle Fusion Middleware 11g is not a single product. It is a product suite, an umbrella label for many products. Typically you don't download the whole media pack - well not unless you want to stage 124 Parts - a total of 68 Gig  - instead you pick the pieces that are required for your chosen Middleware solution. Therefore, you need to research / understand which products are required to build your solution. In this respect, before you go looking for the software pick and persue the product guide from the table below which matches your situation:  Installing a New / Vanilla FMW 11g architecture Oracle Fusion Middleware Installation Planning Guide 11g  Upgrading Oracle Application Server 10g to FMW 11g Oracle Fusion Middleware Upgrade Planning Guide 11g  Patching an existing FMW 11g architecture Oracle Fusion Middleware Patching Guide 11g Certification Information Ok, so now you have an idea of what Fusion Middleware products you need. It's time to check whether these products are certified against your chosen platform. There are two places to find this information:My Oracle Support Certification Tab PageFigure 1.1 My Oracle Support Certification Tab Page - "Search on SOA Suite" Figure 1.2 My Oracle Support Certification Tab Page - "SOA Suite Search Result" The FMW 11g Certification Central Hub (in the format of xls spreadsheet)Figure 2: Screenshot of FMW 11g Release 1 Certification xls spreadsheet Hints / Tips: Fusion Middleware 11g certification information has only recently been added into the Certification Tab page and I think it is the more friendly way to access the information. However, due to some restrictions with the Certification Tab page interface some of the more, let's say obscure certification information, is still to be only found in the Certification spreadsheet. Be aware that to find certification information via the My Oracle Support Certification Tab page you must enter the FMW 11g product name e.g. "Oracle SOA Suite". Do NOT enter "Oracle Fusion Middleware". The certification information does not exist at this product suite level.  For example, if you are building a solution which includes Oracle SOA Suite Oracle WebCenter then you will have to look up the certification information for each product in turn.After choosing the product name, select the latest patch set version. This will not only tell you whether your chosen product is available at that patch set version but provide the certification information relevant to that version.  If the product is not available under the latest patch set version, seek the information under previous patch set versions. Important: Make a careful note of the Oracle WebLogic Server version which is certified with your chosen product and patch set version. Oracle WebLogic Server is the core component of a Oracle Fusion Middleware 11g home. It is important therefore to ensure later on that you download the version of Oracle WebLogic Server which is compatible and certified with your chosen product and patch set version.Also - sorry to state the obvious, but please do not take certification information from the screenshots above. The screenshots are only good for the time they were entered into the blog. To ensure you have the latest information, interactively look up the certification details. For more information about finding certification information, bookmark and readMy Oracle Support Certification Tool for Oracle Fusion Middleware Products [Doc ID 1368736.1]How to Find Certification Details for Oracle Application Server 10g and Oracle Fusion Middleware 11g [Doc ID 431578.1] Downloading the Software Now you should be ready to download the software. There are two download locations Oracle Software Delivery Cloud (formerly known as E-Delivery)Figure 3 - Screenshot of Fusion Middleware Download from Delivery CloudOracle Fusion Middleware Download Page on Oracle Technology NetworkFigure 4 - Screenshot of OTN Product Download Screen Hints / Tips: Your choice of download location should be primarily driven by your licensing needs. Take note of the wording on the OTN site - to quote:"The downloads below are provided for evaluators under the OTN License Agreement. Licensed customers should download their software via our Oracle Software Delivery Cloud site, which offers different license terms."However, it has to be said that the presentation of the most of the product download pages on OTN does make the job easier. The Software Delivery Cloud provides you with a flat list of the Oracle Fusion Middleware 11g media pack. You have to know what you are looking for and pick out the right pieces :-( The OTN product download pages present not only the download for the product you want but also its dependencies such as WebLogic Server and Repository Creation Utility. So, even if your licensing requirements drive you towards the cloud, it is still worthwhile checking the OTN pages if only as a guide to what you need to pick out from the flat list found on the cloud site. Latest Patch Set This is an area which may cause you confusion - especially if you are more familiar with the Oracle Application Server 10g patching story. From Patch Set 11.1.1.6 and higher, the majority of FMW 11g products (N.B there are exceptions) provide installers which can be used both to update existing FMW 11g product installs or build brand new ones. This is good news because, unless you are dealing with one of the exceptions, it means you do not have to download base software and a patch set. At the time of the writing, the two significant exceptions are: Portal/Forms/Reports/Discoverer 11g Release 1 (11.1.1.x) Identity Access Management 11g Release 1 (11.1.1.x) The other key message here is ensure you are grabbing a version of Oracle WebLogic Server which is compatible with your chosen product patch set version. Get this wrong and you will hit errors / problems at AS Instance Configuration Time.The go to place is this document - Oracle Fusion Middleware Download, Installation, and Configuration Readme FilesIn fact, this README document pretty much takes you through what I have blogged above. The only thing is you need to know which README to choose, and that's why planning your FMW 11g technology stack and viewing certification information comes into play beforehand. And Finally As the Oracle Fusion Middleware Download, Installation, and Configuration Readme Files states don't forget to check FMW 11g System Requirements FMW 11g Product Interoperability

• What kind of things are easy in Haskell and hard in Scala, and vice versa?

  - by Daniel C. Sobral

  There has been some intermingling of Scala and Haskell communities, and I have noticed now and then people commenting on stuff that's supposed to be easy in Haskell and hard and Scala. Less often (maybe because I read Scala questions, not Haskell ones), I see someone mentioning that something in Scala is easier than in Haskell. So. I'd like to know from people who are knowledgeable in both what kind of things are easy in Haskell and hard in Scala, and, conversely, what kind of things are easy in Scala and hard in Haskell.
