• Participating in 3 SQL events in 8 days

  - by AaronBertrand

  Well, 8 days not including lead and lag travel time. A quick summary of the three events, and the flights it took to get me to each: SQL Saturday #105 - Dublin, Ireland Flights on March 21st: Providence -> Philadelphia (236 miles) Philadelphia -> Dublin (3,260 miles) Time zone change: +4 when we got there, plus Daylight Saving Time kicked in, so +5 after the event. I spoke at this event, and manned the SQL Sentry booth with cohort Scott Fallen. This event was a fantastic SQL Saturday - very...(read more)

• Are there existing FOSS component-based frameworks?

  - by Tesserex

  The component based game programming paradigm is becoming much more popular. I was wondering, are there any projects out there that offer a reusable component framework? In any language, I guess I don't care about that. It's not for my own project, I'm just curious. Specifically I mean are there projects that include a base Entity class, a base Component class, and maybe some standard components? It would then be much easier starting a game if you didn't want to reinvent the wheel, or maybe you want a GraphicsComponent that does sprites with Direct3D, but you figure it's already been done a dozen times. A quick Googling turns up Rusher. Has anyone heard of this / does anyone use it? If there are no popular ones, then why not? Is it too difficult to make something like this reusable, and they need heavy customization? In my own implementation I found a lot of boilerplate that could be shoved into a framework.

• Building a Roadmap for an IAM Platform

  - by B Shashikumar

  Identity Management is no longer a departmental solution, it has become a strategic part of every organization's security posture. Enterprises require a forward thinking Identity Management strategy. In our previous blog post on "The Oracle Platform Approach", we discussed a recent study by Aberdeen which showed that organizations taking a platform approach can reduce cost by as much as 48% and have 35% fewer audit deficiencies. So how does an organization get started with an Identity Management (IAM) Platform? What are the components of such a platform and how can an organization continuously evolve it for better ROI and IT agility. What are some of the best practices to begin an IAM deployment? To find out the answers and to learn how ot build a comprehensive IAM roadmap, check out this presentation which discusses how Oracle can provide a quick start to your IAM program.  Platform approach-series-building a-roadmap-finalv1 View more presentations from OracleIDM

• Ubuntu boot is slower than Windows 7

  - by Alex Bixel

  One of the reasons I installed Ubuntu (Wubi installer) was for a supposedly quick boot time. My boot time with Windows 7 is about 20-25 seconds, while my boot with Ubuntu is 30-40. I judged the boot times from the time after I selected the operating system on the initial selection menu and the grub menu, respectively. This is even after following all sorts of online guides to improve it. I've done driver profiling (and yes, I remembered to remove the "profile" edit in the grub file afterwards), I've cut a fair few startup programs out, and I've installed the preload package. But I'm still getting startup rates phenomenally slower than Windows 7. Any help here?

• Framework Folders and Duplicate File Names

  - by Kevin Smith

  I have been working with Framework folders a little bit in the past few days and found one unexpected behavior that is different from Contribution Folders (Folders_g). If you try and check a file into a Framework Folder that already exists in the folder it will allow it and rename the file for you. In Folders_g this would have generated an error and prevented you from checking in the file. A quick check of the Framework Folder configuration settings in the Application Administrator’s Guide for Content Server does not show a configuration parameter to control this. I'm still thinking about this and not sure if I like this new behavior or not. I guess from a user perspective this more closely aligns Framework Folders to how Windows handle duplicate file names, but if you are migrating from Folders_g and expect a duplicate file name to be rejected, this might cause you some problems.

• The Future According to Films [Infographic]

  - by Jason Fitzpatrick

  Curious what the future will look like? According to movie directors, casting their lens towards the future of humanity, it’s quite a mixed bag. Check out this infographic timeline to check out the next 300,000 years of human evolution. A quick glance over the timeline shows a series of future where things can quickly go from the fun times to the end-of-the-world times. We’d like to, for example, live it up in the Futurama future of 3000 AD and not the Earth-gets-destroyed future of Titan A.E’s 3028. Hit up the link below for a high-res copy of the infographic.

• Languages with similar features to JavaFX Script

  - by bunglestink

  I just completed a small project in JavaFX, only finding that it has been declared dead by Oracle. JavaFX Script actually seemed to be a pretty interesting language with some neat features for its domain, particularly with bind for data binding and on replace for triggered events. These features actually make the language very useful for small, quick, RIA type apps, which leads to my question: Are there any mainstream languages with features similar to bind and on replace? After working with JavaFX, I got some ideas for some small personal (academic) projects that could take advantage of these features, but I would prefer to not start anything new in a language considered extinct by its owners.

• Why does a computer science degree matter to a professional programmer?

  - by P.Brian.Mackey

  I have a degree in computer science. It has been great for opening doors, getting a job. As far as helping me in the professional field of C# .NET programming (the most popular platform and language in the area I work if not the entire united states on hands down the most popular OS in the world) its hardly useful. Why do you think it helps you as a programmer in your professional career (outside spouting off to prims algorithm to impress some interviewer)? In today's world adaptation, a quick mind, strong communication, OO and fundamental design skills enable a developer to write software that a customer will accept. These skills are only skimmed over in the cs program. In my mind, reading a 500 page C# book by Wrox offers far more useable a skillset than 4 years of the comp sci math blaster courses. Many disagree. So, why does a computer science degree matter?

• is a merchant account a requirment for a website to take payments..

  - by calum

  Hi, I have had a quick look but couldn't see anything related. Basically, if we were to accept payments for events on our website, via paypal (essentially a Buy it now! button), as a business, do we need a merchant's account, or will a regular bank account be acceptable? I may have some confusion in terms. My understanding is you need a merchant's account to accept credit card payments, but as we are using PayPal, is this necessary? Thank you for any clarification. disclaimer - I've read What are some options for taking payments on my website? but it doesn't explicitly say if we require a merchant account or not. Thank you.

• How to prevent a 404 Error when installing a subdomain using a wordpress multi-site installation

  - by Chris

  I have installed a multi-site instillation of WordPress onto my domain. I then added the necessary code to the wp-config.php file and .htaccess as instructed by WordPress. I also installed a plugin called Quick Page/Post Redirect Plugin which allowed me to place a 301 redirect onto the main domain as I only want to use the sub domain and not the main domain. Then I also added the following line of code to the wp-config.php file to redirect the main domain define( 'NOBLOGREDIRECT', 'URL Redirect Address' ); The site works fine with a redirect on the main domain and my subdomain runs fine when you type in subdomain.domain.com or http://subdomain.domain.com. However when I enter www.subdomain.domain.com or http://www.subdomain.domain.com the following error message is returned: Not Found The requested URL / was not found on this server. Apache/2.4.9 (Unix) Server at www.subdomain.domain.com Port 80 Any help with this would be much appreciated.

• YouTube: CoffeeScript Rocks (in NetBeans IDE)

  - by Geertjan

  CoffeeScript is a handy preprocessor for JavaScript, as shown in a quick demo below on YouTube, using the CoffeeScript plugin for NetBeans IDE. Right now, the NetBeans Plugin Portal doesn't have a CoffeeScript plugin for NetBeans IDE 7.4, but not to worry, the NetBeans IDE 7.3 plugin works just fine. http://plugins.netbeans.org/plugin/39007/coffeescript-netbeans Here's a small YouTube clip I made today showing how it all works: Also read this very handy and detailed NetBeans tutorial, on which I based the demo above: https://netbeans.org/kb/docs/web/js-toolkits-jquery.html Related info: http://www.youtube.com/watch?v=QgqVh_KpVKY http://www.ibm.com/developerworks/library/wa-coffee1/ http://blog.sethladd.com/2012/01/vanilla-dart-ftw.html http://api.jquery.com/fadeOut/

• Do PHP-FPM (and other PHP handlers) need execute permissions on the PHP files they're serving?

  - by Andrew Cheong

  I read in a post at Server Fault that PHP-FPM needs execute permissions. However, the answer in When creating a website, what permissions and directory structure? only grants read and write permissions to PHP-FPM. Maybe I don't quite understand how PHP handlers (or CGI in general) work, but the two claims seem contradictory to me. As I understand, when Apache / Nginx gets a request for foobar.php, it "passes" the file to an appropriate handler. That is, I imagine it's as if www-root (or apache or whomever the webserver's running as) were to run some command, /usr/sbin/php-fpm foobar.php Actually, no, that's naive, I just realized. PHP-FPM must be a running instance (if it's to be performant, and cache, etc.), so probably PHP-FPM is just being told, "Hey, quick, process this file for me!" In either case, I don't see why execute permissions are necessary. It's not like the webserver needs to literally execute the file, i.e. ./foobar.php Is the Server Fault answer simply mistaken?

• Offline apt-get update to age of cache

  - by James Haigh

  I have a script to quickly upgrade a Live or fresh system from cached files on a flash drive. In essence, it looks like this: # *Code to remove and symlink /var/cache/apt/ if currently empty of packages.* sudo apt-get dist-upgrade # Quick offline cached upgrade; not limited by slow WANs. echo $'\nMake sure Internet is reachable and press enter for complete online upgrade.'; read sudo apt-get update sudo apt-get dist-upgrade # Complete online upgrade. The problem is that the ‘cached upgrade’ seems to ignore the cached pkgcache.bin and srcpkgcache.bin which is where I assume apt-get update stores its changes, so the upgrade completes as if the system is up-to-date. Useless. So in that case, I need some code to apt-get update to the age of the package cache on my flash drive. This code would be placed between the 1st and 2nd lines of the code above.

• Good ergonomic keyboards for ruby/rails programmer using vim (on Mac) [closed]

  - by Brand

  I'm looking to buy an ergonomic keyboard but I'm unable to find answers for my specific needs. I'm a programmer so I need to be able to have quick/easy access to my curly brace and bracket keys. I use vim extensively so having the ctrl and esc keys in a easier to reach location would help. I'm also a mac user (doing ruby/rails dev). With all these things in mind, what are some good options for ergonomic keyboards? I'm afraid someone will see this as "off topic" but please realize I need to ask fellow programmers. For example, I was thinking of the Kinesis Keyboard but read some reviews saying it's not good for programming. That's when I realized other programmers would be the best at answering this question.

• How to shift development culture from tech fetish to focusing on simplicity and getting things done?

  - by Serge

  Looking for ways to switch team/individual culture from chasing latest fads, patterns, and all kinds of best practices to focusing on finding quickest and simplest solutions and shipping features. My definition of "tech fetish": Chasing latest fads, applying new technologies and best practices without considering product/project impact, focusing on micro optimization, creating platforms and frameworks instead of finding simple and quick ways to ship product features. Few examples of culture differences: From "Spent a day on trying to map database query with five complex joins in NHibernate" to "Wrote a SQL query and used DataReader to pull data in" From "Wrote super-fast JSON parser in C++" to "Used Python to parse JSON response and call C++ code" From "Let's use WCF because it supports all possible communication standards" to "REST is simple text-based format, let's stick with it and use simple HTTP handlers"

• 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

• Determining Whether a String Is Contained Within a String Array (Case Insensitive)

  About once every couple of months I need to write a bit of code that does one thing if a particular string is found within an array of strings and something else if it is not ignoring differences in case. For whatever reason, I never seem to remember the code snippet to accomplish this, so after spending 10 minutes of research today I thought I'd write it down here in an effort to help commit it to memory or, at the very least, serve as a quick place to find the answer when the need arises again.So without further adieu, here it is:Visual Basic Version:If stringArrayName.Contains("valueToLookFor", StringComparer.OrdinalIgnoreCase) Then ... Else ... End IfC# Version:if (stringArrayName.Contains("valueToLookFor", StringComparer.OrdinalIgnoreCase)) ... else ...Without the StringComparer.OrdinalIgnoreCase the search will be case-sensitive. For more information on comparing strings, see: New Recommendations for Using Strings in Microsoft .NET 2.0.Happy Programming!Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

• Visual Studio 2010 Find and Replace With Regular Expressions

  - by Lance Robinson

  Here is a quick notes about using regular expressions in the VS2010 Find Replace dialog.  1.  To create a backreference, use curly braces (“{“ and “}” ) instead of regular parentheses. 2.  To use the captured backreference, use \1\2 etc, where \1 is the first captured value, \2 is the second captured value, etc. Example: I want to find*: info.setFieldValue(param1, param2); and replace it with: SetFieldValue(info, param1, param2); To do this, I can use the following find/replace values: Find what: {[a-zA-Z0-9]+}.setFieldValue\({[a-zA-Z0-9., ]+}\); Replace with: SetFieldValue(\1, \2); Use Regular Expressions is checked, of course. *If you’re wondering why I’d want to do this – because I don’t have control over the setFieldValue function – its in a third party library that doesn’t behave in a very friendly manner.

• Oracle Communications Calendar Server: Upgrading to Version 7 Update 3

  - by joesciallo

  It's been some time since I have posted an entry. Now, with the release of Oracle Communications Calendar Server 7 Update 3, it seems high time to jump start this blog again. To begin with, check out what's new in this release: Authenticating Against an External Directory Booking Window for Calendars Changes to the davadmin Command Enable and Disable Account Autocreation LDAP Pools New Configuration Parameters New Languages New populate-davuniqueid Utility New Schema Objects Non-active Calendar Accounts Are No Longer Searched or Fetched Remote Document Store Authentication The upgrade is a bit more complicated than normal, as you must first apply some new schema elements to your Directory Server(s). To do so, you need to get the comm_dssetup 6.4 patch, patch the comm_dssetup script, and then run the patched comm_dssetup against your Directory Server(s) instances. In addition, if you are using the nsUniqueId attribute as your deployment's unique identifier, you'll want to change that to the new davUniqueId attribute. Consult the Upgrade Procedure for details, as well as DaBrain's blog, before forging ahead with this upgrade.

• Using Interlocked.Exchange(ref Enum, 1) to prevent re-entrancy [migrated]

System.Threading.Interlocked.CompareExchange<TrustPointStatusEnum> (ref tp.TrustPointStatus, TrustPointStatusEnum.NotInitalized,TrustPointStatusEnum.Loading); Based on my research think I have the following options: I can use Threading.SpinWait (for very quick IO tasks) at the cost of CPU I can use Sleep() which has an unreliable wake up time I'm not sure of any other option, but what I want to make sure of is that all these options work with the .NET 4 async and await keywords, especially if I use Task to run them on a background thread
