• How to Get Windows 7 Theme Wallpapers Without Installing Them

  - by Mysticgeek

  Are you using an older version of Windows but like the Windows 7 theme wallpapers? What if you have Windows 7 but you don’t want to install the themes just to get the wallpapers? Here is how to get them without having to install themes. This guest article was written by Ryan Dozier from the Doztech tech blog. Getting the Wallpaper on XP, Vista, or Windows 7 First download and install 7-zip on your machine (link below). After you’ve installed 7-zip, download a Windows 7 theme (link below) and right-click on the theme, select 7-Zip, and Extract to “Theme Name”… A new folder will appear with the theme name on it. When you open it, there will be a folder called DesktopBackground or something similar.   Open the folder to get the wallpapers to view the wallpapers for the theme. You can delete the extra files and just keep the wallpapers!   Getting the Wallpaper on Ubuntu Extracting the wallpaper on Ubuntu can be a little tricky. Just follow these steps and you will be able to do it. First go to the Ubuntu Software Center under the Applications menu. Search for 7zip and click on the arrow to go to the applications menu. Find the Install button and click it. It will take a couple of minutes for 7zip to install. After 7zip installs, close the Ubuntu Software Center and download a Windows 7 theme. Store it somewhere you can access it quickly. Right-click on the theme and select Rename and get rid of the themepack extension and replace it with zip. The file should be “Theme Name.zip” after you rename it. Right-click on the theme and click Extract Here. After  the extracting you will have a new folder with the theme name. Open it and go into the DesktopBackground folder to get the wallpapers. You can delete the extra files and just keep the wallpapers. If you want to get the new Windows 7 Themes Wallpapers, but don’t want to search and install them separately, this is a nice workaround.

Microsoft has agreed to acquire Yammer for 1.2 billion. Personally, I believe that Yammer’s amazing success can be mainly attributed to their wise decision to use Berkeley DB Java Edition as their backend data store. :-) I’m only kidding, of course. However, as Ryan Kennedy points out in the video I recently blogged about, BDB JE did provide the right feature set that allowed them to reliably grow their business. Which in turn allowed them to focus on their core value add. As it turns out, their ‘add’ is quite valuable! This actually makes sense to me, a lot more sense than certain other recent social acquisitions, and here’s why. Last year, IDC declared that we are entering a new computing era, the era of the “3rd Platform.” In case you’re curious, the first 2 were terminal computing and client/server computing, IIRC. Anyway, this 3rd one is more complicated. This year, IDC refined the concept further. It now involves 4 distinct buzzwords: cloud, social, mobile, and big data. Yammer is a social media platform that runs in the cloud, designed to be used from mobile devices. Their approach, using Berkeley DB Java Edition with High Availability, qualifies as big data. This means that Yammer is sitting right smack in the center if IDC’s new computing era. Another way to put it is: the folks at Yammer were prescient enough to predict where things were headed, and get there first. They chose Berkeley DB to handle their data. Maybe you should too!

• Business School graduate joins Oracle

  - by jessica.ebbelaar(at)oracle.com

  My name is Mathias, I work as an Applications Inside Sales Rep for the French market, and I’d like to give you a brief snapshot of my experience at Oracle. First things first, how did you hear about Oracle? Where have you seen the sharp and recognizable red logo? Was it in Charles de Gaulle Airport when your eyes crossed the 20-metre banner with a picture of a strange big machine in the middle? Was it through reading the Forbes 10 top IT companies worldwide ranking? Or is it because IT is your thing and you cannot but know one of the “big four”? Meeting with a Grenoble Alumnus My story is a little different. My plan was to work in sales, in the IT industry. I had heard about Oracle, but my opinion at the time was that this kind of multinational company was way out of reach for a young graduate, even with high enthusiasm and great excitement to be (finally) on the job market. So, I was really surprised when I had an interesting conversation with a top alumnus of my business school. We were at the Grenoble Ecole de Management graduation ceremony (our graduation!), and before the party got really started, I got to chat with her. She told me of the great experience she was getting by living and working in Dublin. She had already figured it all out: “you work with another 100 young people from 10 different nationalities across Europe, you can be based in Dublin, but then once you work really hard you can move to Malaga Spain or other BUs around the world, you can work with different lines of business and learn about new “techy” and business oriented products, move to the field in your home country or elsewhere, etc.” What, what, what? Moving around Europe, trained by the best sales coaches in the world, acquiring strong IT knowledge and getting on board with one of fastest-growing and most watched companies in the world? Well, I was in. The next day (OK, 3 days after, the time to recover), I sent her my CV, and 3 months later I started as a Business Development Consultant at Oracle in Dublin, representing the latest cloud based CRM across the French market. That was 15 months ago. Since then, I moved line of business twice, I’m always learning new things and working with different and senior stakeholders; I have attended hundreds of hours of sales and product training (priceless when you come from a business background); I passed the Dublin Institute of Technology Sales Certification through different trainings given onsite within Oracle; I’ve led projects based around social media and I’ve gotten involved within various sales deals going on my market. Despite all of these great things, two will remain in my spirit: the multiculturalism that I experience every day in the office, and the American style of management - more direct and open than what you can find in “regular French companies”. Sales Progression Board In May 2012, I passed what we call a ‘Sales Progression Board’ to be promoted to an Inside Sales position. I am now in charge of generating revenue through the sale of Oracle applications on my specific territory. Always keeping in my mind my personal ambition: going to the field one day.

• SQL Server Optimizer Malfunction?

  - by Tony Davis

  There was a sharp intake of breath from the audience when Adam Machanic declared the SQL Server optimizer to be essentially "stuck in 1997". It was during his fascinating "Query Tuning Mastery: Manhandling Parallelism" session at the recent PASS SQL Summit. Paraphrasing somewhat, Adam (blog | @AdamMachanic) offered a convincing argument that the optimizer often delivers flawed plans based on assumptions that are no longer valid with today’s hardware. In 1997, when Microsoft engineers re-designed the database engine for SQL Server 7.0, SQL Server got its initial implementation of a cost-based optimizer. Up to SQL Server 2000, the developer often had to deploy a steady stream of hints in SQL statements to combat the occasionally wilful plan choices made by the optimizer. However, with each successive release, the optimizer has evolved and improved in its decision-making. It is still prone to the occasional stumble when we tackle difficult problems, join large numbers of tables, perform complex aggregations, and so on, but for most of us, most of the time, the optimizer purrs along efficiently in the background. Adam, however, challenged further any assumption that the current optimizer is competent at providing the most efficient plans for our more complex analytical queries, and in particular of offering up correctly parallelized plans. He painted a picture of a present where complex analytical queries have become ever more prevalent; where disk IO is ever faster so that reads from disk come into buffer cache faster than ever; where the improving RAM-to-data ratio means that we have a better chance of finding our data in cache. Most importantly, we have more CPUs at our disposal than ever before. To get these queries to perform, we not only need to have the right indexes, but also to be able to split the data up into subsets and spread its processing evenly across all these available CPUs. Improvements such as support for ColumnStore indexes are taking things in the right direction, but, unfortunately, deficiencies in the current Optimizer mean that SQL Server is yet to be able to exploit properly all those extra CPUs. Adam’s contention was that the current optimizer uses essentially the same costing model for many of its core operations as it did back in the days of SQL Server 7, based on assumptions that are no longer valid. One example he gave was a "slow disk" bias that may have been valid back in 1997 but certainly is not on modern disk systems. Essentially, the optimizer assesses the relative cost of serial versus parallel plans based on the assumption that there is no IO cost benefit from parallelization, only CPU. It assumes that a single request will saturate the IO channel, and so a query would not run any faster if we parallelized IO because the disk system simply wouldn’t be able to handle the extra pressure. As such, the optimizer often decides that a serial plan is lower cost, often in cases where a parallel plan would improve performance dramatically. It was challenging and thought provoking stuff, as were his techniques for driving parallelism through query logic based on subsets of rows that define the "grain" of the query. I highly recommend you catch the session if you missed it. I’m interested to hear though, when and how often people feel the force of the optimizer’s shortcomings. Barring mistakes, such as stale statistics, how often do you feel the Optimizer fails to find the plan you think it should, and what are the most common causes? Is it fighting to induce it toward parallelism? Combating unexpected plans, arising from table partitioning? Something altogether more prosaic? Cheers, Tony.

• Move on and look elsewhere, or confront the boss?

  - by Meister

  Background: I have my Associates in Applied Science (Comp/Info Tech) with a strong focus in programming, and I'm taking University classes to get my Bachelors. I was recently hired at a local company to be a Software Engineer I on a team of about 8, and I've been told they're looking to hire more. This is my first job, and I was offered what I feel to be an extremely generous starting salary ($30/hr essentially + benefits and yearly bonus). What got me hired was my passion for programming and a strong set of personal projects. Problem: I had no prior experience when I interviewed, so I didn't know exactly what to ask them about the company when I was hired. I've spotted a number of warning signs and annoyances since then, such as: Four developers when I started, with everyone talking about "Ben" or "Ryan" leaving. One engineer hired thirty days before me, one hired two weeks after me. Most of the department has been hiring a large number of people since I started. Extremely limited internet access. I understand the idea from an IT point of view, but not only is Facebook blocked, but so it Youtube, Twitter, and Pandora. I've also figured out that they block all access to non-DNS websites (http://xxx.xxx.xxx.xxx/) and strangely enough Miranda-IM. Low cubicles. Which is fine because I like my immediate coworkers, but they put the developers with the customer service, customer training, and QA department in a huge open room. Noise, noise, noise, and people stop to chitchat all day long. Headphones only go so far. Several emails have been sent out by my boss since I started telling us programmers to not talk about non-work-related-things like Video Games at our cubicles, despite us only spending maybe five minutes every few hours doing so. Further digging tells me that this is because someone keeps complaining that the programmers are "slacking off". People are looking over my shoulder all day. I was in the Freenode webchat to get help with a programming issue, and within minutes I had an email from my boss (to all the developers) telling us that we should NOT be connected to any outside chat servers at work. Version control system from 2005 that we must access with IE and keep the Java 1.4 JRE installed to be able to use. I accidentally updated to Java 6 one day and spent the next two days fighting with my PC to undo this "problem". No source control, no comments on anything, no standards, no code review, no unit testing, no common sense. I literally found a problem in how they handle string resource translations that stems from the simple fact that they don't trim excess white spaces, leading to developers doing: getResource("Date: ") instead of: getResource("Date") + ": ", and I was told to just add the excess white spaces back to the database instead of dealing with the issue directly. Some of these things I'd like to try to understand, but I like having IRC open to talk in a few different rooms during the day and keep in touch with friends/family over IM. They don't break my concentration (not NEARLY as much as the lady from QA stopping by to talk about her son), but because people are looking over my shoulder all day as they walk by they complain when they see something that's not "programmer-looking work". I've been told by my boss and QA that I do good, fast work. I should be judged on my work output and quality, not what I have up on my screen for the five seconds you're walking by So, my question is, even though I'm just barely at my 90 days: How do you decide to move on from a job and looking elsewhere, or when you should start working with your boss to resolve these issues? Is it even possible to get the boss to work with me in many of these things? This is the only place I heard back from even though I sent out several resume's a day for several months, and this place does pay well for putting up with their many flaws, but I'm just starting to get so miserable working here already. Should I just put up with it?

• Two Weeks To Go, Still Time to Register

  - by speakjava

  Yes, it's now only two weeks to the start of the 17th JavaOne conference! This will be my ninth JavaOne, I came fairly late to this event, attending for the first time in 2002.  Since then I've missed two conferences, 2006 for the birth of my son (a reasonable excuse I think) and 2010 for reasons we'll not go into here.  I have quite the collection of show devices, I've still got the WoWee robot, the HTC phone for JavaFX, the programmable pen and the Sharp Zaurus.  The only one I didn't keep was the homePod music player (I wonder why?) JavaOne is a special conference for many reasons, some of which I list here: A great opportunity to catch up on the latest changes in the Java world.  This is not just in terms of the platform, but as much about what people are doing with Java to build new and cool applications. A chance to meet people.  We have these things called BoFs, which stands for "Birds of a Feather", as in "Birds of a feather, flock together".  The idea being to have sessions where people who are interested in the same topic don't just get to listen to a presentation, but get to talk about it.  These sessions are great, but I find that JavaOne is as much about the people I meet in the corridors and the discussions I have there as it is about the sessions I get to attend. Think outside the box.  There are a lot of sessions at JavaOne covering the full gamut of Java technologies and applications.  Clearly going to sessions that relate to your area of interest is great, but attending some of the more esoteric sessions can often spark thoughts and stimulate the imagination to go off and do new and exciting things once you get back. Get the lowdown from the Java community.  Java is as much about community as anything else and there are plenty of events where you can get involved.  The GlassFish party is always popular and for Java Champions and JUG leaders there's a couple of special events too. Not just all hard work.  Oracle knows how to throw a party and the appreciation event will be a great opportunity to mingle with peers in a more relaxed environment.  This year Pearl Jam and Kings of Leon will be playing live.  Add free beer and what more could you want? So there you have it.  Just a few reasons for why you want to attend JavaOne this year.  Oh, and of course I'll be presenting three sessions which is even more reason to go.  As usual I've gone for some mainstream ("Custom Charts" for JavaFX) and some more 'out there' ("Java and the Raspberry Pi" and "Gestural Interfaces for JavaFX").  Once again I'll be providing plenty of demos so more than half my luggage this year will consist of a Kinect, robot arm, Raspberry Pis, gamepad and even an EEG sensor. If you're a student there's one even more attractive reason for going to JavaOne: It's Free! Registration is here.  Hope to see you there!

• C# Dev Challenge Part 1 of n &ndash; Beginner Edition

  - by mbcrump

  I developed this challenge to test one’s knowledge of C Sharp. I am planning on creating several challenges with different skill sets, so don’t get mad if this challenge doesn’t well challenge you... I noticed that most people like short quizzes so this one only contains 5 questions. All of the challenges are clear and concise of what I am asking you to do. No smoke and mirrors here, meaning that none of the code has syntax errors. The purpose of this exercise is to test several OOP concepts and see how much of the C# language you really know. Question #1 – Lets start off Easy… Will the following code snippet compile successfully? What does this question test? - Can this compile without a namespace? Do you have to have an entry point of “static void Main()”? class Test { static int Main() { System.Console.WriteLine("Developer Challenge"); return 0; } } Answer (select text in box below): Yes, it will compile successfully. Question #2 – What is the value of the Console.WriteLine statements? What does this question test? – Do I understand reference types/value types? If a variable is declared with the @ symbol and its not a reserved keyword does the application compile successfully? using System; internal struct MyStruct { public int Value; } internal class MyClass { public int Value; } class Test { static void Main() { MyStruct @struct1 = new MyStruct(); MyStruct @struct2 = @struct1; @struct2.Value = 100; MyClass @ref1 = new MyClass(); MyClass @ref2 = @ref1; @ref2.Value = 100; Console.WriteLine("Value Type: {0} {1}", @struct1.Value, @struct2.Value); Console.WriteLine("Reference Type: {0} {1}", @ref1.Value, @ref2.Value); } } Answer (select text in box below): Value Type: 0 100 Reference Type: 100 100 Question #3 – What is the value of the Console.WriteLine statements? What does this question test? – Can 2 objects reference the same point in memory? using System; class Test { static void Main() { string s1 = "Testing2"; string t1 = s1; Console.WriteLine(s1 == t1); Console.WriteLine((object)s1 == (object)t1); } } Answer (select text in box below): True True Question #4 – What is the value of the Console.WriteLine statements? What does this question test? – How does the “Stack” work – LIFO or FIFO?   using System; using System.Collections; class Test { static void Main() { Stack a = new Stack(5); a.Push("1"); a.Push("2"); a.Push("3"); a.Push("4"); a.Push("5"); foreach (var o in a) { Console.WriteLine(o); } } } Answer (select text in box below): 5 4 3 2 1 Question #5 – What is the value of the Console.WriteLine statements? What does this question test? – Array and General Looping Knowledge. using System; namespace ConsoleApplication5 { class Program { static void Main(string[] args) { int[] J_LIST = new int[5] { 1, 2, 3, 4, 5 }; int K = 10; int L = 5; foreach (var J in J_LIST) { K = K - J; L = K + 2 * J; Console.WriteLine("J = {0, 5} K = {1, 5} L = {2, 5}", J, K, L); } Console.ReadLine(); } } } Answer (select text in box below): J = 1 K = 9 L = 11 J = 2 K = 7 L = 11 J = 3 K = 4 L = 10 J = 4 K = 0 L = 8 J = 5 K = -5 L = 5 Stay Tuned for more challenges!

• GWT Best Practices - MVP

  - by GWTNewbie

  A question for all the GWT gurus out there. I'm a newbie in GWT and am trying to understand the best practices of coding a GWT application. I have gone through "Large scale application development and MVP" based on Ray Ryan's talk at Google I/O 2009 and it has given me a good starting point. I downloaded the sample source code as well for the Contacts application based on the best practices listed. The application I'm trying to develop using GWT is a bit bigger (in terms of the modules involved) when compared to the sample "Contacts" application & so I want to split it up into multiple functions. I have been reading that having a single Entry point in a GWT application is a good idea, and I don't want to dump all the code in one single AppController class & one single RpcService, what would be the best approach in this situation? How would I go about dispatching the control to multiple controllers? Is there a way to achieve this using some classes in the GWT framework?

• GTK#-related error on MonoDevelop 2.8.5 on Ubuntu 11.04

• Rails Nested Forms Attributes not saving if Fields Added with jQuery

  - by looloobs

  Hi I have a rails form with a nested form. I used Ryan Bates nested form with jquery tutorial and I have it working fine as far as adding the new fields dynamically. But when I go to submit the form it does not save any of the associated attributes. However if the partial builds when the form loads it creates the attribute just fine. I can not figure out what is not being passed in the javascript that is failing to communicate that the form object needs to be saved. Any help would be great. class Itinerary < ActiveRecord::Base accepts_nested_attributes_for :trips end itinerary/new.html <% form_for ([@move, @itinerary]), :html => {:class => "new_trip" } do |f| %> <%= f.error_messages %> <%= f.hidden_field :move_id, :value => @move.id %> <% f.fields_for :trips do |builder| %> <%= render "trip", :f => builder %> <% end %> <%= link_to_add_fields "Add Another Leg to Your Trip", f, :trips %> <p><%= f.submit "Submit" %></p> <% end %> application_helper.rb def link_to_remove_fields(name, f) f.hidden_field(:_destroy) + link_to_function(name, "remove_fields(this)") end def link_to_add_fields(name, f, association) new_object = f.object.class.reflect_on_association(association).klass.new fields = f.fields_for(association, new_object, :child_index => "new_#{association}") do |builder| render(association.to_s.singularize, :f => builder) end link_to_function(name, h("add_fields(this, \"#{association}\", \"#{escape_javascript(fields)}\")")) end application.js function add_fields(link, association, content) { var new_id = new Date().getTime(); var regexp = new RegExp("new_" + association, "g") $(link).parent().before(content.replace(regexp, new_id)); }

• Parsing XML via jQuery, nested loops

  - by Coughlin

  I am using jQuery to parse XML on my page using $.ajax(). My code block is below and I can get this working to display say each result on the XML file, but I am having trouble because each section can have MORE THAN ONE and im trying to print ALL grades that belong to ONE STUDENT. Here is an example of the XML. <student num="505"> <name gender="male">Al Einstein</name> <course cid="1">60</course> <course cid="2">60</course> <course cid="3">40</course> <course cid="4">55</course> <comments>Lucky if he makes it to lab, hopeless.</comments> </student> Where you see the I am trying to get the results to print the grades for EACH student in each course. Any ideas on what I would do? Thanks, Ryan $.ajax({ type: "GET", url: "final_exam.xml", dataType: "xml", success: function(xml) { var student_list = $('#student-list'); $(xml).find('student').each(function(){ $(xml).find('course').each(function(){ gradeArray = $(this).text(); console.log(gradeArray); }); var name = $(this).find("name").text(); var grade = $(this).find("course").text(); var cid = $(this).find("course").attr("cid"); //console.log(cid); student_list.append("<tr><td>"+name+"</td><td>"+cid+"</td><td>"+grade+"</td></tr>"); }); } });

• TDD - testing business rules/validation in ASP.NET MVC

  - by csetzkorn

  Hi, I am using the sharp architecture so I can easily use mocks etc. in my unit tests and/or during TDD. I have quite complicated business rules and would like to test them at the controller level. I am just wondering how other people do this? For me validation tests business rules at three levels: (1) Property level (e.g. property is required) (2) Intra property level (e.g. start date < end date) (3) Persistence level (e.g. name is unique, parent cannot be child of child) My validation framework also assigns errors to properties. I am just wondering what other people do? Do you write a test for each business rule and check whether the correct error message is assigned to the correct property (i.e. looking at the ASP.MVC ModelState)? I hope my question makes sense. Thanks a lot! Best wishes, Christian

• How to add and remove nested model fields dynamically using Haml and Formtastic

  - by Brightbyte8

  We've all seen the brilliant complex forms railscast where Ryan Bates explains how to dynamically add or remove nested objects within the parent object form using Javascript. Has anyone got any ideas about how these methods need to be modified so as to work with Haml Formtastic? To add some context here's a simplified version of the problem I'm currently facing: # Teacher form (which has nested subject forms) [from my application] - semantic_form_for(@teacher) do |form| - form.inputs do = form.input :first_name = form.input :surname = form.input :city = render 'subject_fields', :form => form = link_to_add_fields "Add Subject", form, :subjects # Individual Subject form partial [from my application] - form.fields_for :subjects do |ff| #subject_field = ff.input :name = ff.input :exam = ff.input :level = ff.hidden_field :_destroy = link_to_remove_fields "Remove Subject", ff # Application Helper (straight from Railscasts) def link_to_remove_fields(name, f) f.hidden_field(:_destroy) + link_to_function(name, "remove_fields(this)") end def link_to_add_fields(name, f, association) new_object = f.object.class.reflect_on_association(association).klass.new fields = f.fields_for(association, new_object, :child_index => "new_#{association}") do |builder| render(association.to_s.singularize + "_fields", :f => builder) end link_to_function(name, h("add_fields(this, \"#{association}\", \"#{escape_javascript(fields)} \")")) end #Application.js (straight from Railscasts) function remove_fields(link) { $(link).previous("input[type=hidden]").value = "1"; $(link).up(".fields").hide(); } function add_fields(link, association, content) { var new_id = new Date().getTime(); var regexp = new RegExp("new_" + association, "g") $(link).up().insert({ before: content.replace(regexp, new_id) }); } The problem with implementation seems to be with the javascript methods - the DOM tree of a Formtastic form differs greatly from a regular rails form. I've seen this question asked online a few times but haven't come across an answer yet - now you know that help will be appreciated by more than just me! Jack

• Rails: Should partials be aware of instance variables?

  - by Alexandre

  Ryan Bates' nifty_scaffolding, for example, does this edit.html.erb <%= render :partial => 'form' %> new.html.erb <%= render :partial => 'form' %> _form.html.erb <%= form_for @some_object_defined_in_action %> That hidden state makes me feel uncomfortable, so I usually like to do this edit.html.erb <%= render :partial => 'form', :locals => { :object => @my_object } %> _form.html.erb <%= form_for object %> So which is better: a) having partials access instance variables or b) passing a partial all the variables it needs? I've been opting for b) as of late, but I did run into a little pickle: some_action.html.erb <% @dad.sons.each do |a_son| %> <%= render :partial => 'partial', :locals => { :son => a_son } %> <% end %> _partial.html.erb The son's name is <%= son.name %> The dad's name is <%= son.dad.name %> son.dad makes a database call to fetch the dad! So I would either have to access @dad, which would be going back to a) having partials access instance variables or I would have to pass @dad in locals, changing render :partial to <%= render :partial = 'partial', :locals = { :dad = @dad, :son = a_son } %, and for some reason passing a bunch of vars to my partial makes me feel uncomfortable. Maybe others feel this way as well. Hopefully that made some sense. Looking for some insight into this whole thing... Thanks!

• Problem in IE8 with GET Parameters in opening a new windows with javascript.

  - by amfa95

  Hi, I have a problem with IE8 and the opening of a new window with javascript and submitting parameters with special characters. <a href="javascript:oWin('/html/de/4664286/printregistrationcontent.html?12-security question&#61;Wie hei&#223;t Ihr Lieblingsrestaurant','PRINT',800,600);" class="print">Seite drucken</a> The Problem is the letter 'ß' (sharp S). As you can see the string above is encodes due to anti XSS. This link works in FF and IE6 but IE8 is transmitting the URL Parameter as character with code 65*** (don't know the exaxt value). In the opening window you will only see a square (because character with 65000+ is not printable). I also tried to use URL Encoding instead of HTML encoding <a href="javascript:oWin('/html/de/4664286/printregistrationcontent.html?12-security question%3DWie hei%C3%9Ft Ihr Lieblingsrestaurant','PRINT',800,600);" class="print">Seite drucken</a> If i click on this Link in FF or IE6 it works as expected, but IE8 will fail to transmit the "ß" to the server and therefor will also get it back in the wrong way. If i paste this url to the IE8 it will work too, but not if the window is opened by javascript. The Javascript function oWin is defined as follows function oWin(url,title,sizeH,sizeV) { winHandle = top.open(url,title,'toolbar=no,directories=no,status=yes,scrollbars=yes,menubar=no,resizable=no,width='+sizeH+',height='+sizeV); if(navigator.appVersion.indexOf("MSIE 3",0)==-1) id = setTimeout('winHandle.focus()',1000); } If someone has an idea where to look for the reason please answer to this. Thank you amfa

• Nested dereferencing arrows in Perl: to omit or not to omit?

  - by DVK

  In Perl, when you have a nested data structure, it is permissible to omit de-referencing arrows to 2d and more level of nesting. In other words, the following two syntaxes are identical: my $hash_ref = { 1 => [ 11, 12, 13 ], 3 => [31, 32] }; my $elem1 = $hash_ref->{1}->[1]; my $elem2 = $hash_ref->{1}[1]; # exactly the same as above Now, my question is, is there a good reason to choose one style over the other? It seems to be a popular bone of stylistic contention (Just on SO, I accidentally bumped into this and this in the space of 5 minutes). So far, none of the usual suspects says anything definitive: perldoc merely says "you are free to omit the pointer dereferencing arrow". Conway's "Perl Best Practices" says "whenever possible, dereference with arrows", but it appears to only apply to the context of dereferencing the main reference, not optional arrows on 2d level of nested data structures. "MAstering Perl for Bioinfirmatics" author James Tisdall doesn't give very solid preference either: "The sharp-witted reader may have noticed that we seem to be omitting arrow operators between array subscripts. (After all, these are anonymous arrays of anonymous arrays of anonymous arrays, etc., so shouldn't they be written [$array-[$i]-[$j]-[$k]?) Perl allows this; only the arrow operator between the variable name and the first array subscript is required. It make things easier on the eyes and helps avoid carpal tunnel syndrome. On the other hand, you may prefer to keep the dereferencing arrows in place, to make it clear you are dealing with references. Your choice." Personally, i'm on the side of "always put arrows in, since itg's more readable and obvious tiy're dealing with a reference".

• iOS iPad UIActionSheet Issue

  - by hart1994

  I am currently developing an application which needs an option to 'share' using multiple services; such as email, twitter. To to this, I have a UIBarButtonItem coded in and when touched, it triggers this: UIActionSheet *sheet = [[UIActionSheet alloc] initWithTitle:@"" delegate:self cancelButtonTitle:nil destructiveButtonTitle:nil otherButtonTitles:nil]; [sheet addButtonWithTitle:@"Email"]; [sheet addButtonWithTitle:@"Tweet"]; [sheet addButtonWithTitle:@"Cancel"]; sheet.cancelButtonIndex = sheet.numberOfButtons-1; [sheet showFromRect:self.view.bounds inView:self.view animated:YES]; [sheet release]; In conjunction with this to detect which button is selected: clickedButtonAtIndex:(NSInteger)buttonIndex { if (buttonIndex == actionSheet.cancelButtonIndex) { return; } switch (buttonIndex) { case 0: { [self emailThis]; break; } case 1: { [self tweetThis]; break; } } This works a treat on the iPhone. But unfortunately it displays incorrectly on the iPad. It looks like it is trying to display the UIPopoverController, but it is positioned center of the navbar with practically no height. I have looked into using the UIPopoverController, but I cannot seem to find out how to use it with buttons. Is there anyway I can adapt the code above to properly display the buttons, as it's trying to already. Many thanks, Ryan PS: I'm new to objective-c/iOS coding, so please be specific. Thank you :)

• Using Lambda Expressions trees with IEnumerable

  - by Loathian

  I've been trying to learn more about using Lamba expression trees and so I created a simple example. Here is the code, this works in LINQPad if pasted in as a C# program. void Main() { IEnumerable<User> list = GetUsers().Where(NameContains("a")); list.Dump("Users"); } // Methods public IEnumerable<User> GetUsers() { yield return new User{Name = "andrew"}; yield return new User{Name = "rob"}; yield return new User{Name = "chris"}; yield return new User{Name = "ryan"}; } public Expression<Func<User, bool>> NameContains(string namePart) { return u => u.Name.Contains(namePart); } // Classes public class User { public string Name { get; set; } } This results in the following error: The type arguments for method 'System.Linq.Enumerable.Where(System.Collections.Generic.IEnumerable, System.Func)' cannot be inferred from the usage. Try specifying the type arguments explicitly. However if I just substitute the first line in main with this: IEnumerable<User> list = GetUsers().Where(u => u.Name.Contains("a")); It works fine. Can tell me what I'm doing wrong, please?

• Java UTF-8 to ASCII conversion with supplements

  - by bozo

  Hi, we are accepting all sorts of national characters in UTF-8 string on the input, and we need to convert them to ASCII string on the output for some legacy use. (we don't accept Chinese and Japanese chars, only European languages) We have a small utility to get rid of all the diacritics: public static final String toBaseCharacters(final String sText) { if (sText == null || sText.length() == 0) return sText; final char[] chars = sText.toCharArray(); final int iSize = chars.length; final StringBuilder sb = new StringBuilder(iSize); for (int i = 0; i < iSize; i++) { String sLetter = new String(new char[] { chars[i] }); sLetter = Normalizer.normalize(sLetter, Normalizer.Form.NFC); try { byte[] bLetter = sLetter.getBytes("UTF-8"); sb.append((char) bLetter[0]); } catch (UnsupportedEncodingException e) { } } return sb.toString(); } The question is how to replace all the german sharp s (ß, Ð, d) and other characters that get through the above normalization method, with their supplements (in case of ß, supplement would probably be "ss" and in case od Ð supplement would be either "D" or "Dj"). Is there some simple way to do it, without million of .replaceAll() calls? So for example: Ðonardan = Djonardan, Blaß = Blass and so on. We can replace all "problematic" chars with empty space, but would like to avoid this to make the output as similar to the input as possible. Thank you for your answers, Bozo

• accepts_nested_attributes_for and nested_form plugin

  - by Denis

  Hi folks, I've the following code in a _form.html.haml partial, it's used for new and edit actions. (fyi I use the Ryan Bates' plugin nested_form) .fields - f.fields_for :transportations do |builder| = builder.collection_select :person_id, @people, :id, :name, {:multiple => true} = builder.link_to_remove 'effacer' = f.link_to_add "ajouter", :transportations works fine for the new action... for the edit action, as explain in the doc, I've to add the :id of already existing associations, so, I've to add something like = builder.hidden_field :id, ?the value? if ?.new_record? How can I get the value? Here is the doc of accepts_nested_attributes_for for reference (source: http://github.com/rails/rails/blob/master/activerecord/lib/active_record/nested_attributes.rb#L332) # Assigns the given attributes to the collection association. # # Hashes with an <tt>:id</tt> value matching an existing associated record # will update that record. Hashes without an <tt>:id</tt> value will build # a new record for the association. Hashes with a matching <tt>:id</tt> # value and a <tt>:_destroy</tt> key set to a truthy value will mark the # matched record for destruction. # # For example: # # assign_nested_attributes_for_collection_association(:people, { # '1' => { :id => '1', :name => 'Peter' }, # '2' => { :name => 'John' }, # '3' => { :id => '2', :_destroy => true } # }) # # Will update the name of the Person with ID 1, build a new associated # person with the name `John', and mark the associatied Person with ID 2 # for destruction. # # Also accepts an Array of attribute hashes: # # assign_nested_attributes_for_collection_association(:people, [ # { :id => '1', :name => 'Peter' }, # { :name => 'John' }, # { :id => '2', :_destroy => true } # ]) Thanks for your help.

• How to create a high quality icon for my Windows application?

  - by Patrick Klug

  If you are running Windows with a higher DPI setting you will notice that most application icons on the desktop look terrible. Even high profile application icons such as Google Chrome look terrible while for example Firefox, Skype and MS Office icons look sharp: (example) I suspect that most icons look blurry because a lower resolution icon is scaled up rather than using a higher resolution icon. I want to give my application a high quality icon and can't seem to convince Windows to use the higher resolution icon. I have created a multi-resolution icon with the free icon editor IcoFX. The icon is provided in 16x16, 24x24, 32x32,48x48, 128x128 and 256x256 (!) (all in 32 bit including alpha channel) yet Windows seems to use the 128x128 version of the icon on the desktop and scale it up which looks terrible. (I am using Windows 7 - 64 bit - the icon is placed by means of setting up a shortcut in the msi (created via Visual Studio 2008 Setup Project) and pointing it to the .ico file that contains the multi-resolution icon) I have tried removing the 128x128 icon but to no avail. Interestingly in Windows Explorer the icon looks great even when using the Extra Large Icon setting. How can I create a high quality desktop icon that looks great on higher DPI settings on Windows?

• Python Twitter library: which one?

  - by Parand

  I realize this is a bit of a lazyweb question, but I wanted to see which python library for Twitter people have had good experiences with. I've used Python Twitter Tools and like its brevity and beauty of interface, but it doesn't seem to be one of the popular ones - it's not even listed on the Twitter Libraries page. There are, however, plenty of others listed: oauth-python-twitter2 by Konpaku Kogasa. Combines python-twitter and oauth-python-twitter to create an evolved OAuth Pokemon. python-twitter by DeWitt Clinton. This library provides a pure Python interface for the Twitter API. python-twyt by Andrew Price. BSD licensed Twitter API interface library and command line client. twitty-twister by Dustin Sallings. A Twisted interface to Twitter. twython by Ryan McGrath. REST and Search library inspired by python-twitter. Tweepy by Josh Roesslein. Supports OAuth, Search API, Streaming API. My requirements are fairly simple: Be able to use OAuth Be able to follow a user Be able to send a direct message Be able to post Streaming API would be nice Twisted one aside (I'm not using twisted in this case), have you used any of the others, and if so, do you recommend them? [Update] FWIW, I ended up going with Python Twitter Tools again. The new version supported OAuth nicely, and it's a very clever API, so I stuck to it.

• Fastest Method to Learn Web Design for a Developer

  - by hekevintran

  I am a Web developer and in my projects I have noticed that my weakest point is not being good at the front-end design. Relying on other designers can be annoying if they are not able to produce as quickly as I want. My perspective on HTML/CSS is that it is basically a big hack that amazingly works. There are too many CSS and browser specific bugs/quirks to learn and remember them all without spending extreme amounts of time trying to untangle everything. Is there a fast track route to getting CSS into my brain? I have looked at some CSS books, but to me they really read as long lists of how to render things correctly in IE6 and how to make corners rounded. (Seriously why does it require so many tricks to make a sharp corner round? On any platform but the Web this would be called a major oversight.) Does there exist something that does the analogous to CSS that jQuery does for JavaScript? Using jQuery you don't need to know JavaScript well to make things that work. I am not interested in learning why IE6 does things in weird ways because I don't care about supporting it at all. I am more interested in a method of learning how to use CSS to do what I want without spending hours and hours reading obscure blogs.
