• SearchBar in iPhone Application

  - by Joy

  I have an application for iPhone which requires a search page to search a perticular location. I have created the search view and the main view also. But I'm facing problem when i'm trying to bring up the search view and also when trying to go back to the previous page with the selected cell content.My application is a Tab Bar Application. What My application need is just like the built in clock application in iPhone. When we try to add a new location a search page comes up and after searching the selected item goes back to the previous page. Looking forward for any kind of help Joy

• I'm a CS student, and honestly, I don't understand Knuth's books

  - by Raymond Ho

  I stumbled upon this quote from Bill Gates: "You should definitely send me a resume if you can read the whole thing." He was talking about The Art of Programming books. So I was pretty curious and want to read it all. But honestly, I don't understand it. I'm really not that intellectual. So this should be the reason why I can't understand it, but I am eager to learn. I'm currently reading Volume 1 about fundamental algorithms. Are there any books out there that are friendly for novices/slow people like me, which would help to build up my knowledge so that I can read Knuth's book with ease in the future?

• Microsoft Money alternative?

  - by torbengb

  I'm looking for something to replace my MS Money 2004 application. I've tried KMyMoney which seems pretty simple (that's good!) but it can't import the OFC files I get from my bank, so I would have to enter everything manually = not good. I've tried GnuCash which does import OFC files but I can't wrap my mind around this double-entry philosophy. It may be good for accounting but not for home use. I've tried to make MS Money run in Wine with some success but it was hard to make it work and I'd have to re-do that on my new machine. This is still a useful alternative for me though... Is there a similar tool that can import OFC files and that doesn't do double-entry accounting? Tax capability is not needed for me, I only do after-tax numbers. Some nice dashboard views (upcoming bills, future cash flow, total net worth) and some graphs would be a definite bonus!

• What's new with Java technology? Java Embedded

  - by hinkmond

  As this article points out, Java Embedded is a safer, more robust and easier to develop platform for small networked devices. So, get ready for good things to come from Java Embedded... See: Java Embedded: Next New Thing Here's a quote: Through the past few years the industry as we know it has seen a big boom with the mobile and cloud revolution. Today, there has been an enormous amount of buzz around machine to machine (M2M) or the "Internet of Things," since we are moving into a state where everything is going to have to be interconnected and will have to properly communicate together... Today, Java Embedded provides that platform. I like it! As long as there's no Zombie Apocalypse, I think Java Embedded has a great future! Hinkmond

• Powershell - Splitting variable into chunks

  - by Andrew

  I have written a query in Powershell interrogating a F5 BIG-IP box through it's iControl API to bring back CPU usage etc. Using this code (see below) I can return the data back into a CSV format which is fine. However the $csvdata variable contains all the data. I need to be able to take this variable and for each line split each column of data into a seperate variable. The output currently looks like this: timestamp,"Utilization" 1276181160,2.3282800000e+00 Any advice would be most welcome $SystemStats = (Get-F5.iControl).SystemStatistics ### Allocate a new Query Object and add the inputs needed $Query = New-Object -TypeName iControl.SystemStatisticsPerformanceStatisticQuery $Query.object_name = $i $Query.start_time = $startTime $Query.end_time = 0 $Query.interval = $interval $Query.maximum_rows = 0 ### Make method call passing in an array of size one with the specified query $ReportData = $SystemStats.get_performance_graph_csv_statistics( (,$Query) ) ### Allocate a new encoder and turn the byte array into a string $ASCII = New-Object -TypeName System.Text.ASCIIEncoding $csvdata = $ASCII.GetString($ReportData[0].statistic_data)

• Why does starting a program log me out?

  - by Bruce McKean

  I'm not a computer nerd but have been able to fix Ubuntu/Linux problems in the pass two years with a Google search but this on has me stumped. I upgraded to 12.04 about thirty days ago and all was well except that every time I tried to load KeePassX it would go to the login screen. I installed KeePass2 and all seemed to work. Last week I tried to load Bibble5 (Raw photo editor) and it would try to load and then back to the login screen. After a few days I gave up and downloaded Corel After Shot Pro (Corel's now owns Bibble5) and it has the same problem. Could someone please head me into the steps I need to follow to find out what is the cause? I'm interested in learning more about the Linux system. How to correct any future problems like this? Computer Specification: Processor : 8x Intel(R) Core(TM) i7-2600 CPU @ 3.40GHz Memory : 8155MB (1092MB used) Operating System : Ubuntu 12.04 LTS Graphics Card : GeForce GT 520/PCIe/SSE2

• Not Seeing Ajax Requests In Firebug If Header Has Been Modified

  - by FluidFoundation

  Hey braintrust, I'm making an ajax call using jQuery's library to an api, which requires a username and password encoded to base64 be added to the header. here's a basic example: $.ajax({ type: "GET", contentType: 'application/json', beforeSend:function(xhr){ xhr.setRequestHeader("Authentication", "Basic " + base64EncodedValue); } url: 'https://api.company.com/uri/', complete: function(result) { alert(result); } }); But when this fires off, I get a black alert box, so it doesn't appear as if something is coming back. There is no log in the Firebug console that a get ajax request was done. However, if I remove the beforeSend option, I do see the ajax request get logged, but the request gets back a 'not authorized', so it definitely hit the right place. Any ideas on why it's not showing up in Firebug so I can verify the headers are being sent out correctly?

• Silverlight Goes Mobile!

  - by PeterTweed

  The most exciting announcements from Mix 2010 last week for me were the release of the Windows Phone 7 Series SDK and the news that the platform utilizes Silverlight for the application development technology. From the press and exposure that the platform is being given and the experience that is promised it looks like the Windows Phone 7 Series could eventually compete with the iPhone. For me this is exciting as Silverlight can now be used to develop RIA apps, easily deployed desktop apps and mobile apps. As someone who delivers enterprise technology solutions this equates to a whole bunch of opportunity knocking at the door and asking to join the party. Watch this space for future posts on developing apps on the Windows Phone 7 Series platform!

• User eXperience

  - by Daniel Moth

  The last few months I have been spending a lot of time designing (and help design) the developer experience for the areas I contribute to (in future versions of Visual Studio). As a technical person who defines feature sets, it is easy to get engulfed in the pure technical side of things and ignore the details that ultimately make users "love" using the product to achieve their goal, instead of just "having to use" it. Engaging in UX design helps me escape that trap. In case you are also interested in the UX side of development, I thought I'd share an interesting site I came across: UX myths. In particular, I recommend reading myths 9, 10, 12, 13, 14, 15 and 21. Let me know if there are other UX resources you recommend… Comments about this post welcome at the original blog.

• iPhone, JQTouch and HTML5 audio tags

  - by Moo

  I am having an issue with JQTouch (latest beta) and html5 audio tags on 'sub pages' - the audio tag works before any page transitions are done, and cease to work afterward. For example: http://richardprice.dyndns.ws/test.html and http://richardprice.dyndns.ws/test2.html are identical other than I swap the "current" class between the two divs - all the audio tags play the same mp3. On test.html the audio tag on the initial page works, but when you switch to Page 2 the audio tag on that page does not (and sometimes results in a browser crash). Switch back to Page 1 and the audio tag on that page has ceased to work. test2.html is the same test but with the initial pages reversed, and the same thing happens - Page 2 (now the initial page) plays the audio, Page 1 does not, and switching back to Page 2 results in the audio no longer working. Thoughts?

• SOA Suite 11g (11.1.1.3): Creating a single server domain with SOA Suite and Oracle Service Bus func

  - by Chris Tomkins

  One of the major benefits of the latest version of the Oracle SOA products, SOA Suite 11gR1 PS2 (11.1.1.3) and Oracle Service Bus 11gR1 (11.1.1.3), is that both products depend on the same version of WebLogic Server 11g (10.3.3) and so can be installed in the same domain. If you are a developer building artifacts for both but with a laptop/desktop with limited resources then this is particularly useful, as you can install a single server domain (by default you get a domain with an admin server and multiple managed servers) which incorporates both sets of functionality. The viewlet below shows you how to go about creating such a single server domain, using the configuration wizard. Just click the Play button from the viewlet menu to start it. Note: As you have added all this functionality into a single server, it will take a few minutes to start up. As this is my first foray into the world of viewlets I’d be interested in your opinion as to whether you have found this useful and any tips/techniques for improving any future viewlets I may create.

• Can an Aspect conditionally render parts of a JSP page ?

  - by Scott The Scot

  At present the jsp pages have normal authorize tags to conditionally render links and information etc. The website is on the intranet, and we're using Spring Security 2.0.4. Ive now got a business user who wants to allow all roles to access everything for the first few weeks, then gradually add the security back in as feedback is gathered from the business. Rather than go through every page, removing the authorize tags, only to have to put them back in, is is possible to configure these through an aspect, or is there any other way to externalize this into a config file ? I've found Spring's MethodSecurityInterceptor and the meta data tags, but these wouldn't give me the externalization. I've been on google for the last hour, and am now pretty sure this can't be done, but would love to find out I haven't been asking the right questions. Advice appreciated

• Stop default hashtag behavior with jquery

  - by scatteredbomb

  I'm using the following code to append a hashtag to the end of a url. That way someone can copy that url and take them back to that page, with certain divs visable. $("a.live").click(function() { window.location.hash = 'live'; $("#live).slideDown(); }); In this example I have a div called 'live', that would slideDown when a link is clicked, and '#live' added to the url. Then I have code that checks the hash tags when the page is loaded to show the proper divs. My problem is, how do I prevent the browser from jumping to the 'live' div once it's called? I don't want the page to scroll down to the div, just want it opened and the hashtag appended so a person could copy it and come back to that page with that div showing. Any tips? Thank you!

• How to schedule a cron job to backup a MySql database every week?

  - by KevinM

  What is a command line I can use to back up a MySql database every single week into a file name with the date (so that it doesn't collide with previous backups)? Also, is this a reasonable backup strategy? My database is relatively small (a complete export is only 3.2 megs right now). The churn rate is relatively low. I need to be able to get the complete DB back if something goes wrong. And it would be extra cool if there's a way that I could see the changes that occur across a time span.

• Get the caret position when losing focus in WPF

  - by DrLazer

  I have two textbox's. I have an event setup for the "onLostFocus" of the textbox's. If i finish typing a word into both boxes one after the other all is well. At the point where i click back on the first textbox i want to click halfway through the word (perfectly resonable thing for a user to do). When the onLostFocus event fires here is my code : void tbox_LostFocus(object sender, RoutedEventArgs e) { IInputElement focusedelement = FocusManager.GetFocusedElement(this); if (focusedelement is TextBox) { TextBox focusedTextBox = focusedelement as TextBox; int focusIndex = m_commandsStacker.Children.IndexOf(focusedTextBox); int caretIndex = focusedTextBox.CaretIndex; The caret index is 0. At that point I refresh the whole form and set parameters and all other kinds of whizzery, storing the texbox index and caret position to put everything back the same. Why does it return 0 and not the position where the caret should be halfway between the word?

• How do I set PATH variables for all users on a server?

  - by Rob S.

  I just finished installing LaTeX for my company's Ubuntu server that we all SSH into to use. At the end of the install it says this: Add /usr/local/texlive/2010/texmf/doc/man to MANPATH, if not dynamically determined. Add /usr/local/texlive/2010/texmf/doc/info to INFOPATH. Most importantly, add /usr/local/texlive/2010/bin/x86_64-linux to your PATH for current and future sessions. So, my question is simply: How do I do this so that these variables are set for all users on the system? (And yes, I have sudo permissions). Thanks in advance to any and all responses I receive.

• SQL Server 2008 R2: StreamInsight changes at RTM: Count Windows

  - by Greg Low

  Another interesting change in the RTM version of StreamInsight is the addition of a new window type. Count Windows aren't time based but are based on counting a number of events. The window type provided in this release is called CountByStartTimeWindow. Based on that name, you'd have to presume we might get other types of count windows in the future. This new window type takes two parameters. The first is the number of events. The second is an output policy, similar to the policies now required for...(read more)

• Adding HTML to the DOM through the client.

  - by Mantorok

  Hi all Just wanted your views on the most efficient way to render content on demand, the reason this has come to light is that I'm maintaining a AA compliant website and we recently added video to it, and one of the techniques to avoid invalidation was to add the HTML for the video to the DOM after the page has loaded - which is fine and working ok. However, I found 2 possible techniques and I would appreciate some views, the one I'm currently using is an AJAX call that returns the HTML, the other technique is a hidden field that contains the HTML - I'm presently using the former. The main reason I'm asking the question is because there may be times when this particular control is also requested via an AJAX call, so I would end up with back-to-back AJAX calls, which seems a bit inefficient to me. I hope this makes sense, are there any better techniques to achieve this? Am I worrying too much over the consecutive AJAX calls? Thanks

• jQuery Autocomplete losing text on AutoPostBack

  - by Moose

  I have a jQuery Autocomplete field on an ASP.Net Webform and everything has been working great until now. I also have a DropDownList that I have a need to fire onSelectedIndexChanged with AutoPostBack. When I changed my code to do the AutoPostBack, the text field that has the jQuery AutoComplete on it comes back blank. However, if I look at the source of the page, the text is in the text field. If I now post the form, the page will send back a blank field. My Google-Fu is weak on this one, as I could not come up with any workaround for it. Has anyone had any issues like this with the Autocomplete field getting blanked out on an AutoPostBack, and how did you get around it? I can post code if it's really necessary, but I'd need to sanitize a lot of it before I could due to company policy.

• What are some of best Javascript memory detecting tools?

  - by Philip Fourie

  Our team is faced with slow but serious Javascript memory leak. We have read up on the normal causes for memory leaks in Javascript (eg. closures and circular references). We tried to avoid those pitfalls in the code but it likely we still have unknown mistakes left in our code. I started my search for available tools but would like input from people with actual experience with these tools. Some of the tools I found so far (but have no idea how good and useful they would be for our problem): Sieve Drip JavaScript Memory Leak Detector Our search is not limited to free tools, it will be a bonus, but more importantly something that will get the job done. We do the following in our Javascript code: AJAX calls to a .NET WCF back-end that send back JSON data Manipulate the DOM Keep a fairly sized object model in the Javascript to store current state

• Designing an API on top with Java RMI and Rest APIs

  - by user1303881

  I'm working on the backend of a java web application. We have a document repository (Fedora Commons specifically) where we house xml files. I want to abstract the API of the repository internally so that we aren't tightly coupled to one product. I'd also like to give the flexibility of connecting to to a repository via Java RMI or REST APIs. I was hoping to get advice or resources on how to implement something like this. My thought it that I'd have some abstract repository class that had methods like getRecord, updateRecord, and deleteRecord. In the constructor I would pass the URI for the repository and the API method and port. This would allow some flexibility in the future so that if the REST api became more practical, but allow the flexibility or using RMI which could (should?) have better performance. Am I over thinking this or am I on the right path?

• Should I commit or rollback a transaction that creates a temp table, reads, then deletes it?

  - by Triynko

  To select information related to a list of hundreds of IDs... rather than make a huge select statement, I create temp table, insert the ids into it, join it with a table to select the rows matching the IDs, then delete the temp table. So this is essentially a read operation, with no permanent changes made to any persistent database tables. I do this in a transaction, to ensure the temp table is deleted when I'm finished. My question is... what happens when I commit such a transaction vs. let it roll it back? Performance-wise... does the DB engine have to do more work to roll back the transaction vs committing it? Is there even a difference since the only modifications are done to a temp table? Related question here, but doesn't answer my specific case involving temp tables: http://stackoverflow.com/questions/309834/should-i-commit-or-rollback-a-read-transaction
