• Rewriting .each() loop as for loop to optimize, how to replicate $(this).attr()

  - by John B

  I running into some performance issues with a jquery script i wrote when running in ie so I'm going through it trying to optimize any way possible. Apparently using for loops is way faster than using the jQuery .each method. This has led me to a question regarding the equivalent of $(this) inside a for loop. I'm simplifying what I'm doing in my loop down to just using an attr() function as it gets across my main underlying question. Im doing this with each(simplified) var existing = $('#existing'); existing.each(function(){ console.log($(this).attr('id')); }); And I've tried rewriting it as a for loop as such: var existing = $('#existing'); for(var i = 0;i < existing.length;i++) { console.log(existing[i].attr('id')); } Its throwing an error saying: Uncaught TypeError: Object #<HTMLDivElement> has no method 'attr' Thanks.

• Passenger problem: "no such file to load" -- /config/environment

  - by Mason Jones

  I've been researching this one and found references to similar problems here and there, but none of them has led to a solution yet. I've installed passenger (2.2.11) and nginx (0.7.64) and when I start things up and hit a Rails URL, I get an error page informing me of a load error: no such file to load -- /path/to/app/config/environment From what I've found online this appears to be some sort of a user/permissions error, but I've tried all the logical fixes: I've made sure that /config/environment.rb is not owned by root, but by a webapp user. I've tried setting passenger_default_user, I've tried setting passenger_user_switching off. I've even tried setting the nginx user, though that shouldn't matter much. I've gotten some differing results, but nothing's actually worked. I'm hoping someone may have the magical combination of settings and permissions for this. I may try backing down to an earlier version of Passenger, because I've never had this issue before; it's been a little while since I set up Passenger though. Thanks for any suggestions.

• What's the state of support for SHA-2 in various platforms?

  - by Cheeso

  I read that SHA-1 is being retired from the FIPS 180-2 standard. Apparently there are weaknesses in SHA-1 that led to this decision. Can anyone elaborate on the basis for that decision? Are there implications for the use of SHA-1 in commercial applications? My real questions are: What is the state of SHA-2 support in various class libraries and platforms? Should I attempt to move to SHA-2? Interested in mainstream platforms: .NET, Java, C/C++, Python, Javascript, etc.

• First and last window don't show up.

  - by SirGregg

  Hi, I'm creating a WinApi application for my programming course. The program is supposed to show an LED clock using a separate window for each 'block'. I have figured most of it out, except for one thing: when creating the two-dimensional array of windows, the first and last window never show up. Here's the piece of code from the InitInstance function: for (int x=0;x<8;x++) for (int y=0;y<7;y++) { digitWnd[x][y] = CreateWindowEx((WS_EX_LAYERED | WS_EX_TRANSPARENT | WS_EX_NOACTIVATE | WS_EX_STATICEDGE), szWindowClass, szTitle, (WS_POPUP| WS_BORDER), NULL, NULL, NULL, NULL, dummyWnd, NULL, hInstance, NULL); ShowWindow(digitWnd[x][y], nCmdShow); UpdateWindow(digitWnd[x][y]); } The same loop bounds are used everytime I interact with the windows (set position and enable/disable). All the windows seem to be working fine, except for digitWnd[0][0] and digitWnd[7][6]... Any ideas as to what is happening?

• what are the limitations of mobile phones and web development

  - by Kieran

  simple really.. I am have been asked to do a mobile site (straight html + css (+ maybe jquery mobile later on)). The site will need to support the new type smart phone and the old type Nokia/(Symbian OS) with the web browser. Doubts and reservations aside as to anyone without a smart phone would bother visiting this site it still needs to support it. My first question is do older phones support PNG images and transparancey... But this has led me to a much broader question of what are some of the limitations of developing for older phone platforms is there anything that has caught mobile web devs out and had them scratching their head for an afternoon.. what are the limitations of mobile phones?

• What was the thinking behind the development of Object Oriented Programming?

  - by leeand00

  I've got some real nay-sayers on my hands here, and I'm trying to give them the reason why OOP was developed in the first place. I realize that OOP is not perfect for all problems and situations, but it was developed for a reason... My guess would be, that a few of those reasons would be: Maintainability Re-usability Document-ability Abstraction of Complex Technologies Dynamic Extension at Runtime... Probably some things that I'm not even aware of yet... But I really don't have much to back this up, and I was wondering why OOP was developed in the first place, and it's history. What were the people who developed OOP trying to accomplish? What led them to develop OOP?

• XPath : finding an attribute node (and only one)

  - by subtenante

  What is the XPath to find only ONE node (whichever) having a certain attribute (actually I'm interested in the attribute, not the node). For example, in my XML, I have several tags having a lang attribute. I know all of them must have the same value. I just want to get any of them. Right now, I do this : //*[1][@lang]/@lang, but it seems not to work properly, for an unknown reason. My tries have led me to things ranging from concatenation of all the @lang values ('en en en en...') to nothing, with sometimes inbetween what I want but not on all XML. EDIT : Actually //@lang[1] can not work, because the function position() is called before the test on a lang attribute presence. So it always takes the very first element found in the XML. It worked best at the time because many many times, the lang attribute was on root element.

• List.AddRange inline declaration

  - by AJ

  Hello, This may seem an easy question, but not to me, also a search has led to nothing. Up until now the only .net programming I have done is with Delphi Prism. With Prism I can do things like: var l := new List<String>(['A','B','C']); or var l := new List<String>; l.AddRange(['A','B','C']; but can I do a similar thing in C#, or do I have to do it like: var a = new String[] {"A","B","C"}; var l = new List<String>(a); Thanks, AJ

• Server-side Audio Editor

  - by Kristen

  I am looking for an audio editor that we can use server side (ASP + IIS) We want users to be able to upload an audio file, and then offer a 10 second teaser clip to other users for download. Ideally I would like our application to be able to specify Input and Output Filename, Start and End time (or Duration), and be able to fade-in and fade-out, and equalise the volume. Maybe some audio editors have a batch edit facility, and it would just be a question of installing on the server? All the keywords I have tried putting into Google have led me on a wild goose chase, hopefully someone can help me with suggestions. Thanks.

• What data (if any) persists across web-requests in Ruby on Rails?

  - by Daniel Beardsley

  I decided to use the singleton design pattern while creating a view helper class. This got me thinking; will the singleton instance survive across requests? This led to another question, Which variables (if any) survive across web requests and does that change depending on deployment? (Fastcgi, Mongrel, Passenger, ...) I know that Controller instance variables aren't persisted. I know Constants are persisted (or reloaded?). But I don't know about class variables, instance variables on a class, Eigenclasses, ...

• About the leading newline in Visual Studio solution files.

  - by mafutrct

  Sometimes, for unknown reasons, VS 2008 creates solution files led by a newline. Microsoft Visual Studio Solution File, Format Version 10.00 # Visual Studio 2008 [...] This happened on various machines, and I have no idea why this is. A Google search did not yield any useful results. Now, why do I worry about this? Because I can't open these solutions in Windows Explorer. I have to open VS, select File - Open - Solution and it works fine. But to open solutions from within Explorer, I have to edit the sln file and remove the leading newline. Edit: After Leom's suggestion I tested a few times and found that the issue is solely dependent on the leading newline.

• Optimising a query for Top 5% of users

  - by Nai

  On my website, there exists a group of 'power users' who are fantastic and adding lots of content on to my site. However, their prolific activities has led to their profile pages slowing down a lot. For 95% of the other users, the SPROC that is returning the data is very quick. It's only for these group of power users, the very same SPROC is slow. How does one go about optimising the query for this group of users? You can assume that the right indexes have already been constructed. EDIT: Ok, I think I have been a bit too vague. To rephrase the question, how can I optimise my site to enhance the performance for these 5% of users. Given that this SPROC is the same one that is in use for every user and that it is already well optimised, I am guessing the next steps are to explore caching possibilities on the data and application layers?

• Ask the Readers: Do You Use the Command Line?

  - by Asian Angel

  Most people have heard of it but not everyone is familiar or comfortable with how to use this bastion of geekdom. This week we would like to know if you use the command line or not. The command line…the bastion of ultimate geekery in many peoples’ eyes. You often hear people referring to doing things using the command line, so there must be something to it, right? For some people using the command line is the best, most efficient, and easiest way to do things on their systems. These are the people that many of us wish we were like. Next you have those who are proficient at using the command line but do not rely on it for everything they do on their systems. Then there are people who know how to perform some tasks or hacks using the command line but may not be as comfortable or knowledgeable as they wish to be using it. Moving on you find those who are interested in learning how to use the command line and just need a small push to get started.  Perhaps you feel too intimidated to learn it and just need the right opportunity to come along. And maybe you do not care one way or the other so long as you get done what you want to do on your system. Or you may prefer to simply use a graphical interface since that is quicker and easier for you (along with being familiar). You can find the whole range of people when it comes to using the command line… This week we would like to know if you use the command line or not. What command line category do you fit into?

• SQL SERVER – 4 Tips for ETL Software IDE Developers

  - by pinaldave

  In a previous blog, I introduced the notion of Semantic Types. To an end-user, a seamlessly integrated semantic typing engine significantly increases the ease of use of an ETL IDE (integrated development environment, or developer studio). This led me to think about other ease-of-use issues I have encountered while building ETL applications. When I get stumped while programming, I find myself asking the variations on these questions: “How do I…?” “Now what?” “Why isn’t this working?” “Why do I have to redo the work I just did?” It seems to me that a good ETL IDE will anticipate these questions and seek to answer them before they are even asked. So here are my tips to help software vendors build developer IDEs that actually make development easier. How do I…? While developing an ETL application, have you ever asked yourself: “How do I set up the connection to my SQL Server database?”,“How do I import my table definitions from Access?”, etc. An easy answer might be “read the manual” but sometimes product manuals are not robust or easily accessible. So, integrating robust how-to instructions directly into your ETLstudio would help users get the information they need at the time they need it. Now what? IDEs in general know where you last clicked or performed an action using an input device such as a keyboard; so they should be able to reasonably predict the design context you are in and suggest the next steps accordingly. Context-sensitive suggestions based on the state of the user’s work will help users move forward in ETL application development. Why isn’t this working? Or why do I have to wait till I compile to be told about a critical design issue? If an ETL IDE is smart enough to signal to users what in their design structures is left to be completed or has been completed incorrectly, then the developer can spend much less time in the designàcompileàerror-correct loop. Just-in-time validation helps users detect and correct programming errors earlier in the ETL development life cycle. Why do I have to redo the work I just did? In ETL development, schemas, transformation rules, connectivity objects, etc., can be reused in various situations. Using mouse-clicks to build and manage libraries of reusable design objects implies that the application development effort should decrease over time and as the library acquires more objects. I met a great company at SQL Pass that is trying to address many of these usability issues. Check them out at www.expressor-software.com. What other ease-of-use suggestions do you have for ETL software vendors? Please post your valuable comments. ?Reference: Pinal Dave (http://blog.SQLAuthority.com) Filed under: Best Practices, Pinal Dave, PostADay, SQL, SQL Authority, SQL Query, SQL Server, SQL Tips and Tricks, T SQL, Technology Tagged: ETL

• Friday Fun: Factory Balls – Christmas Edition

  - by Asian Angel

  Your weekend is almost here, but until the work day is over we have another fun holiday game for you. This week your job is to correctly decorate/paint the ornaments that go on the Christmas tree. Simple you say? Maybe, but maybe not! Factory Balls – Christmas Edition The object of the game is to correctly decorate/paint each Christmas ornament exactly as shown in the “sample image” provided for each level. What starts off as simple will quickly have you working to figure out the correct combination or sequence to complete each ornament. Are you ready? The first level serves as a tutorial to help you become comfortable with how to decorate/paint the ornaments. To move an ornament to a paint bucket or cover part of it with one of the helper items simply drag the ornament towards that area. The ornament will automatically move back to its’ starting position when the action is complete. First, a nice coat of red paint followed by covering the middle area with a horizontal belt. Once the belt is on move the ornament to the bucket of yellow paint. Next, you will need to remove the belt, so move the ornament back to the belt’s original position. One ornament finished! As soon as you complete decorating/painting an ornament, you move on to the next level and will be shown the next “sample Image” in the upper right corner. Starting with a coat of orange paint sounds good… Pop the little serrated edge cap on top… Add some blue paint… Almost have it… Place the large serrated edge cap on top… Another dip in the orange paint… And the second ornament is finished. Level three looks a little bit tougher…just work out your pattern of helper items & colors and you will definitely get it! Have fun decorating/painting those ornaments! Note: Starting with level four you will need to start using a combination of two helper items combined at times to properly complete the ornaments.

• Automapper: Handling NULL members

  - by PSteele

  A question about null members came up on the Automapper mailing list.  While the problem wasn’t with Automapper, investigating the issue led to an interesting feature in Automapper. Normally, Automapper ignores null members.  After all, what is there really to do?  Imagine these source classes: public class Source { public int Data { get; set; } public Address Address { get; set; } }   public class Destination { public string Data { get; set; } public Address Address { get; set; } }   public class Address { public string AddressType { get; set; } public string Location { get; set; } } And imagine a simple mapping example with these classes: Mapper.CreateMap<Source, Destination>();   var source = new Source { Data = 22, Address = new Address { AddressType = "Home", Location = "Michigan", }, };   var dest = Mapper.Map<Source, Destination>(source); The variable ‘dest’ would have a complete mapping of the Data member and the Address member. But what if the source had no address? Mapper.CreateMap<Source, Destination>();   var source = new Source { Data = 22, };   var dest = Mapper.Map<Source, Destination>(source); In that case, Automapper would just leave the Destination.Address member null as well.  But what if we always wanted an Address defined – even if it’s just got some default data?  Use the “NullSubstitute” option: Mapper.CreateMap<Source, Destination>() .ForMember(d => d.Address, o => o.NullSubstitute(new Address { AddressType = "Unknown", Location = "Unknown", }));   var source = new Source { Data = 22, };   var dest = Mapper.Map<Source, Destination>(source); Now, the ‘dest’ variable will have an Address defined with a type and location of “Unknown”.  Very handy!

• Why it may be good to be confused: Mary Lo Verde’s Motivational Discussion at Oracle

  - by user769227

  Why it may be good to be confused: Mary Lo Verde’s Motivational Discussion at Oracle by Olivia O'Connell Last week, we were treated to a call with Mary LoVerde, a renowned Life-Balance and Motivational Speaker. This was one of many events organized by Oracle Women’s Leadership (OWL). Mary made some major changes to her life when she decided to free herself of material positions and take each day as it came. Her life balance strategies have led her from working with NASA to appearing on Oprah. Mary’s MO is “cold turkey is better than dead duck!”, in other words, knowing when to quit. It is a surprising concept that flies in the face of the “winners don’t quit” notion and focuses on how we limit our capabilities and satisfaction levels by doing something that we don’t feel passionately about. Her arguments about quitting were based on the conception that ‘“it” is in the way of you getting what you really want’ and that ‘quitting makes things easier in the long run’. Of course, it is often difficult to quit, and though we know that things would be better if we did quit certain negative things in our lives, we are often ashamed to do so. A second topic centred on the perception of Confusion Endurance. Confusion Endurance is based around the idea that it is often good to not know exactly what you are doing and that it is okay to admit you don’t know something when others ask you; essentially, that humility can be a good thing. This concept was supposed to have to Leonardo Da Vinci, because he apparently found liberation in not knowing. Mary says, this allows us to “thrive in the tension of not knowing to unleash our creative potential” An anecdote about an interviewee at NASA was used to portray how admitting you don’t know can be a positive thing. When NASA asked the candidate a question with no obvious answer and he replied “I don’t know”, the candidate thought he had failed the interview; actually, the interviewers were impressed with his ability to admit he did not know. If the interviewee had guessed the answer in a real-life situation, it could have cost the lives of fellow astronauts. The highlight of the webinar for me? Mary told how she had a conversation with Capt. Chesley B. "Sully" Sullenberger who recalled the US Airways Flight 1549 / Miracle on the Hudson incident. After making its descent and finally coming to rest in the Hudson after falling 3,060 feet in 90 seconds, Sully and his co-pilot both turned to each other and said “well...that wasn’t as bad as we thought”. Confusion Endurance at its finest! Her discussion certainly gave food for thought, although personally, I was inclined to take some of it with a pinch of salt. Mary Lo Verde is the author of The Invitation, and you can visit her website and view her other publications at www.maryloverde.com.

• The Missing Post

  - by Joe Mayo

  It’s somewhat of a mystery how the writing process can conjure up results that weren’t initially intended. Case in point is the fact that another post was planned to be in place of this one, but it never made the light of day.  This particular post started off as an introduction to a technology I had just learned, used, and wanted to share the experience with others.  The beginning was fun and demonstrated how easy it was to get started.  One of the things I’ve been pondering over time is that the Web is filled with introductions to new technologies and quick first looks, so I set out to add more depth, share lessons learned, and generally help you avoid the problems I encountered along the way; problems being a key theme of why you aren’t reading that post at this very minute.  Problems that curiously came from nowhere to thwart my good intentions. Success was sweet when using the tool for the prototypical demo scenario. The thing is, I intended the tool to accomplish a real task.  Having embarked on the path toward getting the job done, glitches began creeping into the process.  Realizing that this was all a bit new, I had patience and found a suitable work-around, but this was to be short lived. As in marching ants to a freshly laid out picnic, the problems kept coming until I had to get up and walk away.  Not to be outdone, sheer will and brute force manual intervention led to mission accomplishment.  Though I kept a positive outlook and was pleased at the final result, the process of using the tool had somewhat soured. Regardless of a less than stellar experience with the tool, I have a great deal of respect for the company that produced it and the people who built it. Perhaps I empathize for what they might feel after reading a post that details such deficiencies in their product.  Sure, if you’re in this business, you’ve got to have a thick skin; brush it off, fix the problem, and move on to greatness. But, today I feel like they’re people and are probably already aware of any issues I would seemingly reveal.  Anyone who builds a product or provides a service takes a lot of pride in what they do.  Sometimes they screw up and if their worth a dime, they make it up. I think that will happen in this case and there’s no reason why I should post information that has the potential to sound more negative than helpful.  While no one would ever notice or care either way, I’m posting something that won’t harm.

• MVVM Light Toolkit V3 SP1 for Windows Phone 7

  - by Laurent Bugnion

  He he I start to sound like Microsoft… Anyway… I just released a service pack (SP1) for MVVM Light Toolkit V3. Why? Well mostly because I worked a bit more with the Windows Phone 7 tools that were released at MIX0, and I noticed a few things that could be better in the Windows Phone 7 template. Also, I only found out at MIX that you can actually install custom project templates for Visual Studio Express. For some reason I thought it was not possible. The best way to solve these issues is through a service pack, which consists of a few zip files. Simply follow the instructions on the “Installing Manually” page. You can go ahead and overwrite the files that were installed with V3, all the file structure and names are exactly the same. What? So what do you get in this service pack that was not already in V3? (for more info about what’s new in V3, check the What’s New page). Project and Item templates for Visual Studio 10 Express (phone edition). Unzip these files in your “My Documents” folder, and you can now create a new MVVM Light application in the WinPhone7 version of Visual Studio 2010 Express. Signed assemblies: All the assemblies are now signed, which is a requirement in certain build configurations. XML documentation files: Thanks to Matt Casto for pinging me and reminding me that I had forgotten to include them (doh). New and improved Windows Phone 7 assemblies and templates: This one deserves its own section (see below). What was wrong with the old Silverlight 3 assemblies in Windows Phone 7 projects? It was kind of weird. Functionality wise, it was working just right. However, if you noticed, the EventToCommand behavior was not visible in the Assets tab of Expression Blend, under Behaviors, where it should normally have been. The reason was that even though the Windows Phone 7 is using Silverlight 3, the System.Windows.Interactivity that Blend was expecting is the version that is normally used in Silverlight 4. Yeah, I know, it’s weird. This led me to create a specific version of these assemblies for the phone. The assemblies are located into C:\Program Files\Laurent Bugnion (GalaSoft)\Mvvm Light Toolkit\Binaries\WP7. There are 3 DLLs: GalaSoft.MvvmLight.WP7.dll with RelayCommand, Messenger and ViewModelBase GalaSoft.MvvmLight.Extras.WP7.dll with EventToCommand and DispatcherHelper System.Windows.Interactivity.dll which is the same DLL installed in the Blend SDK, and which is needed for the EventToCommand behavior to work. Happy coding! That’s all! Download and install the service pack according to the instructions on the Installation page, and create your first MVVM Light application for the phone (a blog post will follow later with more details).   Laurent Bugnion (GalaSoft) Subscribe | Twitter | Facebook | Flickr | LinkedIn

• Taking AIIM at Social

  - by Christie Flanagan

  Today we are pleased to have a guest post from Christian Finn (@cfinn).  Christian is Senior Director of Product Management for Oracle WebCenter and heads up the WebCenter evangelist team.Last week I had the privilege of speaking at AIIM’s new conference in San Francisco.  AIIM, for those of you not familiar with it, is a global community of information professionals and got its start with ECM and imaging long ago. With 65,000+ members, AIIM has now set about broadening its scope to focus more on the intersection between systems of record (think traditional ECM) and systems of engagement (think social solutions).  So AIIM’s conference is a natural place to be for WebCenter types like me, who have a foot in both of those worlds.AIIM used to have their name on a very large tradeshow, but have changed direction now to run a small, intimate conference.  The lineup of keynotes was terrific, including David Pogue of The New York Times, Clay Shirky, author of Here Comes Everybody, and Ted Schadler, author of Empowered among many thought-provoking and engaging speakers. (Note: Ted will soon be featured in our Social Business webcast series. Stay tuned.)John Mancini and his team at AIIM did a fabulous job running the event and the engagement from the 450 attendees was sustained over the two and a half days.  Our proudest moment was having three finalists up for AIIM awards including: San Joaquin County, CA, for a justice case management system using WebCenter Content and Oracle BPM; Medtronic and Fishbowl Solutions for their innovative iPad solutions on WebCenter Content, and the government of Louisville, Kentucky/Jefferson County for their accounts payable solution using WebCenter Content’s Image & Process Management.  The highlight of the awards night was San Joaquin winning the small organization award against some tough competition.In addition to the conversations sparked at the show, AIIM promoted the whitepapers their industry task forces have produced on the impact and opportunities created by systems of engagement and systems of record. The task forces were led by: Geoffrey Moore, the renowned high tech marketing guru and author of Crossing The Chasm; and Andrew McAfee, who coined the term and wrote the book, Enterprise 2.0. (Note: Andy will also be featured soon on the Social Business webcast series.)  These free papers make short, excellent reading and you can download them on the AIIM website: Moore highlights the changes to Enterprise IT that the social revolution will engender, and McAfee covers where and how organizations are finding value in using social techniques to foster innovation, to scale Q&A across the organization, and to connect sales and marketing for greater efficiency and effectiveness. Moore’s whitepaper is here and McAfee’s whitepapers are available here. For the benefit of those who did not get a chance to attend the AIIM conference, I’ll be posting the topics of my AIIM presentation, “Three Principles for Fixing Your Broken Organization,” here on the WebCenter blog over the rest of this week and next in a series of posts.
