• Building TimeZone object in Java

  - by Harish

  I build a Java TimeZone object using the TimeZone String like GMT-8,GMT,PST,EST etc. This did not consider whether the timezone is daylight saving enabled or not.Now there is a requirement to include this check and instead of giving the input as PDT or EDT the daylight saving is given as a seperate flag.I am not sure whether TimeZone has a direct method to change the dayLight saving property of that TimeZone. So if I get an input like PST and DaylightSaving as true then I have to change the string as PDT.Whats even worse is sometimes I will get inputs like GMT-8 or GMT-6 with Day light flag as either true or false. Is there a way out ? I can't use thirdparty TimeZone related classes Code Sample: TimeZone timeZone = TimeZone.getTimeZone("EST"); TimeZone timeZone = TimeZone.getTimeZone("PST"); TimeZone timeZone = TimeZone.getTimeZone("GMT-8");

• Log4j Grouping application logs

  - by mhanda

  Hi, I am trying to group logs of multiple related applications to a single log file. For example I have 3 applications A1.esb, A2.esb, A3.esb. I want all the logs from these 3 applications get logged to a single log file called A.log. Similarly, I want B.log for B1.esb, B2.esb and B3.esb. I am using log4j in JBoss application server. I have tried to use TCLFilter but I only succeeded in getting individual applications logging to individual log files. As in, A1.esb logging to A1.log, A2.esb logging to A2.log and so on. But I couldn't figure out a way of grouping these loggings.

• Migrating from CPython to Jython

  - by itsadok

  I'm considering moving my code (around 30K LOC) from CPython to Jython, so that I could have better integration with my java code. Is there a checklist or a guide I should look at, to help my with the migration? Does anyone have experience with doing something similar? From reading the Jython site, most of the problems seem too obscure to bother me. I did notice that: thread safety is an issue Unicode support seems to be quite different, which may be a problem for me mysqldb doesn't work and needs to be replaced with zxJDBC Anything else? Related question: What are some strategies to write python code that works in CPython, Jython and IronPython

• One to many too much data returned - MySQL

  - by Evan McPeters

  I have 2 related MySQL tables in a one to many relationship. Customers: cust_id, cust_name, cust_notes Orders: order_id, cust_id, order_comments So, if I do a standard join to get all customers and their orders via PHP, I return something like: Jack Black, jack's notes, comments about jack's 1st order Jack Black, jack's notes, comments about jack's 2nd order Simon Smith, simon's notes, comments about simon's 1st order Simon Smith, simon's notes, comments about simon's 2nd order The problem is that *cust_notes* is a text field and can be quite large (a couple of thousand words). So, it seems like returning that field for every order is inneficient. I could use *GROUP_CONCAT* and JOINS to return all *order_comments* on a single row BUT order_comments is a large text field too, so it seems like that could create a problem. Should I just use two separate queries, one for the customers table and one for the orders table? Is there a better way?

• Where to place ClientAccessPolicy.xml for Local WCF Service?

  - by cam

  I'm trying to create a basic WCF Service and Silverlight client. I've followed the following tutorial: http://channel9.msdn.com/shows/Endpoint/Endpoint-Screencasts-Creating-Your-First-WCF-Client/ Since Silverlight 4 was incompatible with the WSHttpBinding, I changed it to BasicHttpBinding. Unfortunately I keep getting this error now: "An error occurred while trying to make a request to URI'**'.This could be due to attempting to access a service in a cross-domain way without a proper cross-domain policy in place, or a policy that is unsuitable for SOAP services. You may need to contact the owner of the service to publish a cross-domain policy file and to ensure it allows SOAP-related HTTP headers to be sent." I placed clientaccesspolicy.xml in the root directory of the WCF project (which is in the same solution as the Silverlight client). This did not solve the problem. What do I need to do?

• Import AppleScript methods in another AppleScript?

  - by DASKAjA

  Is there a way to use defined AppleScript methods in other AppleScripts which reference the original AppleScript with something similar to import (f.e. in PHP)? I wrote a methode to set Skype status and mood-text: on setSkypeStatus(status, mood_text) tell application "System Events" set skypeRunning to count (every process whose name is "Skype") if skypeRunning > 0 then --only set status if skype is running tell application "Skype" set myStatus to "SET USERSTATUS " & status set myMood to "SET PROFILE MOOD_TEXT " & mood_text send command myStatus script name "AppleScript" send command myMood script name "AppleScript" return skypeRunning end tell else return skypeRunning end if end tell end setSkypeStatus now I'm searching for something like import skype_methods.scpt. Is there such a functionality. I can't something related with Google.

• No Microphone error on iPod Touch

  - by Bob Vork

  I've build an iPhone app that should work on an iPod Touch as well, but I'm getting reports that the app is not working on iPod touches. It's displaying an error message saying there's no mic available on the device. The thing is, the app does nothing whatsoever with audio, and I can't find anything related in the project settings. The other problem is I don't have an iPod Touch available to test this myself. Are some people running an old firmware version? Am I compiling the wrong firmware version? To my surprise I couldn't find anything about this on SO or Google… Any help is appreciated

• AnkhSVN Commits Are Very Slow

  - by jakdep

  Recently, I had to move my SVN repositories to a different server, but I am experiencing some performance problems since the move. I am using Visual Studio 2005, AnkhSVN 2.1.7819.411 and TortoiseSVN 1.6.6 on my workstation and VisualSVN Server on the server which runs Windows Server 2008. Whenever I try to commit a file or view the file history in Visual Studio it takes twenty odd seconds. I confirmed that an exception has been made for VisualSVN Server on the server's firewall, but when I disable the server's firewall the performance is back to normal (1-2 seconds for a commit). When I do a commit or check the log on a file in TortoiseSVN the performance is fine as well. To ensure that the problem was not related to the moving of the repositories, I am running these tests against a new repository which was created on the new server. So, I reckon the problem lies with AnkhSVN, but am at a loss as how to diagnose it further. Any help would be greatly appreciated.

• Detect Installed Application URI Handler on Webkit browsers

  - by Punit Raizada

  Guys, I have a question mainly related to the Iphone web browser but I am hoping the same solution would work on other browsers that are webkit based. I have a application (Iphone + Android) that registers a handler for custom URI (appuri://) on the Phone. I am able to launch the application by making a link to "appuri://act/launch" from my web pages. This works only if my application is installed on the device. If the device does not have the app installed then a message comes up "Safari was not able to open ....". What I want to do is detect if the URI Scheme is supported from the browser and then prompt my own message saying "please download the app ..blah blah blah" if the handler for the URI scheme is not found. Is there a way I can detect or find the list of URL Scheme handlers on the Phone from the Web Browser ?

• Difference between focus and focus-in(out)-event signals

  - by spajak

  Hello What's the difference between "focus" and "focus-in(out)-event" signals in GTK+? Which one is emitted firs? How are they related to keyboard(TAB) & mouse clicks. Do they depend on each other? I'm asking this because I want to keep track of currently focused widget within toplevel window and I don't want to test HAS_FOCUS flag of every widget when I need it. The widgets I'm interested of are deep inside other containers, boxes etc. What would be the best way in this situation for keeping & updating focused widget pointer?

• Enumerations and String values in ASP.NET

  - by Jason

  I'm looking for some best practice advice on enumerations and retrieving an associated string value. Given this: public enum SerialKillers { TedBundy, EdGein, AlbertFish, GeorgeBush } What is the best way to get a related string value of the name? Eg. "Ted Bundy", given that the string value may not match the representation in the enumeration. eg "George W Bush" My current thinking is function accepting an enum and returning a string, but would that not mean hard coding the string values (which I prefer not to do)? Is using a resources file where the string can be retrieved via the enumeration too heavy handed? Should I accept the fact I am going to Hell for victimising Ted Bundy by associating him with George Bush?

• *Client* scalability for large numbers of remote web service calls

  - by Yuriy

  Hey Guys, I was wondering if you could share best practices and common mistakes when it comes to making large numbers of time-sensitive web service calls. In my case, I have a SOAP and an XML-RPC based web service to which I'm constantly making calls. I predict that this will soon become an issue as the number of calls per second will grow. On a higher level, I was thinking of batching those calls and submitting those to the web services every 100 ms. Could you share what else works? On a lower level side of the things, I use Apache Xml-Rpc client and standard javax.xml.soap.* packages for my client implementations. Are you aware of any client scalability related tricks/tips/warnings with these packages? Thanks in advance Yuriy

• Enterprise distribution Program for iPhone

  - by Mohammed Sadiq

  Hi all, I would like to implement a application which backs up all the internal datas like sms, mms, videos, audios, documents, call history stored in iPhone. But this seems to be not possible with api docs that the apple has released so far ... I have gone through the pdf of ENterprise distribution program and some of the links related to Enterprise Distribution Program, specifies about the Remote wipe and accessing of internal datas like Calendar, sms, mms ect .... But they didnt mention how to do it programmatically. Does Apple provide any special priviledges like extra api support to access the internal data in their Enterprise Distribution Program?. Is there any difference between Enterprise Distribution Program and Standard Distribution Program in the development point of view? And since in-house distribution does not require Apple approval, shall we use some other method which are not officially mentioned in apple docs, to access the internal stored data .. If so can anyone point out the way to do it? Any help would be greatly appreciated awaiting for your response Best regards, Mohammed Sadiq ....

• Get Members of Band

  - by user168083

  If I look at the Freebase page for the band '311', I see Chad Sexton listed. http://www.freebase.com/view/en/311 I am trying to query for the members of a band : { "name" : "311", "/music/artist/album" : [{"name":null, "id":null, "optional": true}], "type|=" : ["/music/artist","/music/musical_group"], "/award/award_winner/awards_won" : ["award":null, "optional" => true], "/award/award_nominated_work/award_nominations" : ["award":null, "optional" => true], "/music/artist/supporting_artists":[{}] } I thought supporting_artists would return the band member names, but the array is always empty. But if I query for all properties related to Chad Sexton, I don't see 311 mentioned. But he is listed as member on the Freebase web info page (which is correct). { "*": null, "name": "Chad Sexton", "type": "/music/artist" } How can I grab the band member names along with the band info?

• UITableView section header and section footer not updating (redraw problem)

  - by Gerd

  I have a UITableView grouped style with custom header and footer view. Inside the footer I put a UILabel and a UIButton. Clicking on the button hides or show some rows, updates the UILabel in the footer view and finally resizes footer view. Basically everything is working fine. BUT the text ion the label is not updated on the screen. It is updated in the UILabel text property, but only if I scroll the section footer out of the visible area and scroll it back, it is updated. So it's a typical redraw problem here of the UITableView. I tried every method to force update like needsLayout etc. Nothing helped. I have seen some related questions but with some different behaviour and no solution. Any help/ideas? Thanks, Gerd

• Using a C#.net DLL in Node.js / serverside javascript

  - by Dve

  I have spent a while playing with node.js and exploring related frameworks such as express and geddy... and I am very impressed, especially with the WebSockets implementation in socket.io. I have a pet project that is an online game, the entire game engine is written in C# and I would like to know if there is anyway I can call the functions of this existing dll from a solution built using node.js, socket.io, express etc? The game engine itself is pretty complete; tested and robust. I am hoping there is some neat way of exposing its functionality without to much overhead. Thanks

• State Machine WF: Issues with workflow termination

  - by AgentHunt

  Hello, We have a state machine workflow for maintaining the state of an application submitted by a user. One of the issues I am having is related to workflow termination. In one of the states, I had a bug. When the application reached that state, it threw an exception and as a result, the terminate event of the workflow was called and the particular workflow instance got removed from the persistence database. So I am not able to load that workflow instance anymore. I would have hoped, if there is an error in one of the states, an exception would be thrown(so that we know what the issue is), yet the entire workflow instance should not disappear. Can the fault handler activity ensure that the workflow does not terminate. Also, is there a way, when the terminate event is called, the instances do not get removed from the persistence store. Thanks for any help/suggestions.

• Query only the first detail record for each master record

  - by Neal S.

  If I have the following master-detail relationship: owner_tbl auto_tbl --------- -------- owner --- owner auto year And I have the following table data: owner_tbl auto_tbl --------- -------- john john, corvette, 1968 john, prius, 2008 james james, f-150, 2004 james, cadillac, 2002 james, accord, 2009 jeff jeff, tesla, 2010 jeff, hyundai, 1996 Now, I want to perform a query that returns the following result: john, corvette, 1968 jeff, hyundai, 1996 james, cadillac, 2002 The query should join the two tables, and sort all the records on the "year" field, but only return the first detail record for each master record. I know how to join the tables and sort on the "year" field, but it's not clear how (or if) I might be able to only retrieve the first joined record for each owner. Three related questions: Can I perform this kind of query using LINQ-to-SQL? Can I perform the query using T-SQL? Would it be best to just create a stored procedure for the query given its likely complexity?

• Eclipse uses 100 % CPU randomly

  - by Florian Gutmann

  Hi everyone! My eclipse sometimes starts using 100 % of my CPU very spontaneously. I can't figure out why it needs that much CPU usage. There is no background task like "building workspace" running. After some time the CPU load drops to 0 and everything is normal. I can't find any information related to the problem in workspace/.metadata/.log file. Has anybody some tip how i can figure out which part of eclipse is using the CPU so heavily? Is there a way to get a thread dump of eclipse? The kill -3 on the eclipse process doesn't do anything. Eclipse Version: Galileo JavaEE Operating System: Linux 2.6.31 Thanks in advance! Florian
