  • Confused by this PHP Exception try..catch nesting

    - by Domenic
    Hello. I'm confused by the following code: class MyException extends Exception {} class AnotherException extends MyException {} class Foo { public function something() { print "throwing AnotherException\n"; throw new AnotherException(); } public function somethingElse() { print "throwing MyException\n"; throw new MyException(); } } $a = new Foo(); try { try { $a->something(); } catch(AnotherException $e) { print "caught AnotherException\n"; $a->somethingElse(); } catch(MyException $e) { print "caught MyException\n"; } } catch(Exception $e) { print "caught Exception\n"; } I would expect this to output: throwing AnotherException caught AnotherException throwing MyException caught MyException But instead it outputs: throwing AnotherException caught AnotherException throwing MyException caught Exception Could anyone explain why it "skips over" catch(MyException $e) ? Thanks.

  • Analyzing CPU usage of an iOS application

    - by Mustafa
    I'm working on an application that constructs springboard like interface (like iPhone's home screen). I have multiple pages, and each page contains many subviews. Each subview is able to detect touch and hold event. Once a touch and hold event is recognized, all the subviews start to wobble. One of the problems that i'm facing is that the CPU usage shoots to 99%, when the subviews are in wobble state, and i change the page. Instruments has a tool by the name of "CPU Sampler". I'm unable to find good set of documentation for this tool. I don't know how to read the output generated by this tool. Can anyone give me a small tutorial or guidelines? Can i check which piece of code is responsible for the CPU activity?

  • Is Sphinx better than LaTex in writing manuals/books?

    - by Masi
    Only a few people recommended to use Sphinx at the beginning of the year. Sphinx has developed rather fast recently. I noted today that Sage has made a change from direct editing with LaTex to Sphinx. This is evident in William Stein's answer on 2nd April about Sage's tutorial The tutorial is not a latex document anymore. It's an entirely different Sphinx document that can output pdf. It suggests me that Sphinx may be at a level such that it is suitable for me. Is Sphinx better than LaTex in writing manuals/books?

  • UX Design Question: Should a multi step wizard save the form contents when the user clicks 'go back'

    - by Ashwin Prabhu
    I am developing a web application that collects data over multiple steps through a wizard. Steps are generally not interdependent, in that data input at each step has little or no effect on the consequent steps. However each step may have a set of validations which determine whether the user can progress to the next step by clicking 'continue' What should be the behavior when the user clicks previous? a Quickly move to the previous page, thus losing all the unsaved data in the form. Prompting the user with a warning is an option, but it can become irritating quite soon. b Move to the previous page saving all the data in the current step - without triggering validations, so that when the user comes back she sees the form in the same state that she left it in. c any other behaviour All opinions are welcome :)

  • Mono 2.10.5 Runtime error on Ubuntu 11.10

    - by johnluetke
    I've install mono-runtime via apt in order to run my Mono console application on Ubuntu via SSH. However, when I run the command mono myapp.exe, It exits, with no message, and my program does nothing. If I throw the -v switch to Mono, such as mono -v myapp.exe, I get about 10k lines of output (as expected, -v is verbose), with the first few lines being: converting method System.OutOfMemoryException:.ctor (string) Method System.OutOfMemoryException:.ctor (string) emitted at 0xb7052c28 to 0xb7052c4b (code length 35) [myapp.exe] converting method (wrapper runtime-invoke) <Module>:runtime_invoke_void__this___object (object,intptr,intptr,intptr) Method (wrapper runtime-invoke) <Module>:runtime_invoke_void__this___object (object,intptr,intptr,intptr) emitted at 0xb7052c68 to 0xb7052cf6 (code length 142) [myapp.exe] converting method System.SystemException:.ctor (string) I read this as the runtime throwing an OutOfMemory exception, but the machine is under no intense load, has plenty of available RAM, and is running nothing other that system processes. I've removed and reinstalled Mono countless times, and have even run the executable on other machines perfectly fine. Am I missing something completely obvious here?

  • Help with Regex statement in Ruby

    - by user336777
    I have a string called 'raw'. I am trying to parse it in ruby in the following way: raw = "HbA1C ranging 8.0—10.0%" raw.scan /\d*.?\d+[ ](-+|\342\200\224)[ ]\d*.?\d+/ The output from the above is []. I think it should be: ["8.0—10.0"]. Does anyone have any insight into what is wrong with the above regex statement? Note: \342\200\224 is equal to '—'. The piece that is not working is: (-+|\342\200\224) I think it should be equivalent to saying, match on 1 or more '-' OR match on the string \342\200\224. Any help would be greatly appreciated it!

  • Reverse Breath First Search in C#

    - by Ngu Soon Hui
    Anyone has a ready implementation of the Reverse Breath First Search algorithm in C#? By Reverse Breath First Search, I mean instead of searching a tree starting from a common node, I want to search the tree from the bottom and gradually converged to a common node. Let's see the below figure, this is the output of a Breath First Search: In my reverse breath first search, 9,10,11 and 12 will be the first few nodes found ( the order of them are not important as they are all first order). 5, 6, 7 and 8 are the second few nodes found, and so on. 1 would be the last node found. Any ideas or pointers?

  • One big call vs. multiple smaller TSQL calls

    - by BrokeMyLegBiking
    I have a ADO.NET/TSQL performance question. We have two options in our application: 1) One big database call with multiple result sets, then in code step through each result set and populate my objects. This results in one round trip to the database. 2) Multiple small database calls. There is much more code reuse with Option 2 which is an advantage of that option. But I would like to get some input on what the performance cost is. Are two small round trips twice as slow as one big round trip to the database, or is it just a small, say 10% performance loss? We are using C# 3.5 and Sql Server 2008 with stored procedures and ADO.NET.

  • Webserver for publishing adjusted images

    - by Petr Prikryl
    I want to create webserver which will be receiving data (images probably) from webclients who will be uploading these photos. And then the webserver must execute some graphic programs (client select whichone) to modify the image(s). After the graphic program is done, the results (output image(s)) will be uploaded to the web temp database (by webserver) to publish results of graphic programs. I found the C++ web toolkit (http://www.webtoolkit.eu), but I'm not sure if this is a suitable C/C++ library for me because I haven't any experiences with making C/C++ web apps/servers. Can someone tell me some advice please? The webserver should have some SDK too, for adding next graphic programs. I'm searching only for any C/C++ tools/libraries/etc.

  • MySQL Cluster data nodes - slow SELECTs

    - by Boyan Georgiev
    Hi to all. First off, I'm new to MySQL Cluster. This is my pain: I've managed to setup a MySQL Cluster with two data nodes, two SQL nodes and one management server. Everything works pretty well, except the following: my data nodes are spread across an intranet link which incurs latency into communications between the data nodes. Apparently, due to MySQL Cluster's internal partitioning schemes, when my PHP application pulls data from the cluster via SELECT queries, parts of the data are pulled from both data nodes. This makes the page appear onscreen REALLY slowly. If I bring one data node offline, the data can only be pulled from that single remaining data node, and thus, the final result (HTML output) appears on the screen in a very timely fashion. So, my question is this: can the data nodes/cluster be told to pull data from partitions stored only on a particular data node?

  • How do i pass a number from a list as a parameter in scheme?

    - by wyatt
    I need to take a number from a list and convert it to a number so that i can pass it as a parameter. im trying to make a 1-bit adder in scheme. i've written the code for the or gate and the xor gate and also the half adder and now im trying to combine them all to make a full adder. im not sure if im going about it the right way. any input will be appreciated thank you. (define or-gate (lambda (a b) (if (= a 1) 1 (if (= b 1) 1 0)))) (define xor-gate (lambda (a b) (if (= a b) 0 1))) (define ha (lambda (a b) (list (xor-gate a b)(and-gate a b)))) (define fa (lambda (a b cin) (or-gate (cdr(ha cin (car (ha a b))))(cdr(ha a b))))) the issue i get when i run the program is that the half adder (ha) function outputs a list as a value and that makes the values incompatible with my other procedures because they require numbers and not lists. i feel like there is a simple solution but i dont know it.

  • noob iPhone "count" frustrations!?!?!

    - by codemonkey
    Okay, I know I must be doing something incredibly stupid here. Here's the sample code (which, when executed within a viewDidLoad block silently crashes... no error output to debug console). NSMutableArray *bs = [NSMutableArray arrayWithCapacity:10]; [bs addObject:[NSNumber numberWithInteger: 2]]; NSLog(@"%@", [bs count]); [bs release]; What am I missing? Oh... and in case anyone is wondering, this code is just me trying to figure out why I can't get the count of an NSMutableArray that actually matters somewhere else in the program.

  • Can't get ellipsis to work on Android

    - by Mark
    Hi, I have a TextView. I want it to ellipsize if longer than its available width. This does not work unless the input string has no spaces... can anyone provide an example of this working? I've tried different combinations of: singleLine="true" maxLines="1" scrollHorizontally="false" none of these have any effect. Again, if I supply a string that has no spaces in it, then the ellipsis appears correctly. What am I missing? I've tried this on 1.5, 1.6, 2.0, all same problem. Thanks

  • SQL one table aggrigation

    - by Lostdrifter
    Ok, for the last few days I have been attempting to find a method to pull a very important set of information form a table that contains what I call daily counts. I have a table that is setup as follows. person|company|prod1|prod2|prod3|gen_date Each company has more then one person, and each person can have different combination of products that they have purchased. What I have been trying to figure out is a SQL statement that will list the number of people that have bought a particular product per company. So an output similar to this: Comp ABC | 13 Prod1 | 3 Prod2 | 5 Prod 3 Comp DEF | 2 Prod1 | 15 Prod2 | 0 Prod 3 Comp HIJ | 0 Prod1 | 0 Prod2 | 7 Prod 3 Currently if a person did not select a product the value being stored is NULL. Best I have right now is 3 different statements that can produce this information if run on there own. SELECT Count(person) as puchases, company FROM Sales WHERE prod1 = '1' and gendate = '3/24/2010' Group BY company

  • Perl, deleting an .xml file created and open with IO::File and XML::Writer?

    - by Sho Minamimoto
    So I'm running through a list of things and have code that creates an .xml file with IO::File called $doc, then I make a new writer with XML::Writer(OUTPUT = $doc). More code runs and I build a big xml file with XML::Writer. Then, near the end of the file, I find out if I need this file at all. If I do need it, I just $writer-end(); $doc-close(); but if I don't need it, what should I enter to just delete all data I've stored/saved and move onto the next file? I tried unlink($docpath) (before and after $doc-close()), the file was not deleted.

  • Ruby on Rails when create method fails, render loses local variables

    - by Jimmy
    Hey guys I have a simple create method with some validations and whenever the create method fails due to validation errors it re-renders the 'new' action. The problem is in my new action/view I have a local variable that is established in the action and passed to a partial to render some related information to what the user is creating. Now when my create action fails and I try to re-render the 'new' action I'm getting the always awesome undefined method `cover' for nil:NilClass error. What is the best way to handle re-establishing my action's local variables on a render instead of redirecting to the action again and the user losing the data they input?

  • Powershell Select-Object from array not working

  • Beginning android: how to map a string to a list

    - by user569421
    I just finished the NotepadV1-3 tutorial for Android apps, and I was thinking of creating my own inventory app for fun, which for now basically consists of a list of names (such as "DVD" or "Grocery"), each of which can be clicked, which will bring up another specific list associated with that name. However, with the SQLiteDatabase.insert(..) method, the ContentValue can only take (among many others) "String, String" as argument, and I can't figure out how to input into the database a list of Strings associated with a particular key. I'm having trouble researching on how to resolve this as I am not that familiar with SQL. What would be the best way to store a key with its associated list of Strings? Any pointers and suggestions are appreciated! Android newb :[

  • Error safe/correcting resource identifier

    - by Martin
    The receiver is my website, the sender is the same but the medium is noisy, a user. He will read an alphanumeric code of length 6 and later input the same code to identify a resource. A good use for a error correcting code, I thought, and rather than do the research I thought I'd just put the question out there. Or I might be going about it the wrong way, since the situation is rather like sending a perfect dictionary along with every transmission. The requirements on the code are simply: 6 alphanumeric digits, to start with until I run out, anyway. If the user gets it wrong I should still be able to identify the right resource. No resource is preferable to the wrong one. Easy to code or have free libraries for .net Any suggestions?
