  • Perl, print with newline

    - by Mike
    In perl most of my print statements take the form print "hello." . "\n"; Is there a nice way to avoid keeping all the pesky "\n"s lying around? I know I could make a new function such as myprint that automatically appends \n, but it would be nice if I could override the existing print.

  • iphone - compiler conditional on header

    - by Mike
    I have a project that generates applications for two targets. One of the targets has to include one additional delegate protocol that should not be present on the other one. So, I have created a macro on Xcode and declared the header like this: #ifdef TARGET_1 @interface myViewController : UIViewController <UIScrollViewDelegate, UIPopoverControllerDelegate> #endif #ifdef TARGET_2 @interface myViewController : UIViewController <UIScrollViewDelegate> #endif { .... bla bla.... } The problem is that Xcode is not liking this "double" declaration of @interface and is giving me all sort of problems. How to solve that? thanks for any help.

  • Experienced developer trying to get outsourcing contract with current client.

    - by Mike
    I work for a major bank as a contract software developer. I've been there a few months, and without exception this place has the worst software practices I've ever seen. The software my team makes has no formal testing, terrible code (not reusable, hard to read, etc), minimal documentation, no defined development process and an absolutely sickening amount of waste due to bureaucratic overhead. Part of my contract is to maintain a group of thousands of very poorly written batch jobs. When one of the jobs fails (read: crashes), it's a developers job to look at the source, figure out what's wrong, fix it, and check it in. There is no quality assurance process or auditing of the results whatsoever. Once the developer says "it works" a manager signs off and it goes into production. What's disturbing is that these jobs essentially grab market data and put it into a third-party risk management system, which provides the bank with critical intelligence. I've discovered the disturbing truth that this has been happening since the 90s and nobody really has evidence the system is getting the correct data! Without going into details, an issue arose on Friday that was so horrible I actually stormed out of the place. I was ready to quit, but I decided to just get out to calm my nerves and possibly go back Monday. I've been reflecting today on how to handle this. I have realized that, in probably less than 6 months, I could (with 2 other developers) remake a large component of this system. The new system would provide them with, as primary benefits, a maintainable codebase less prone to error and a solid QA framework. To do it properly I would have to be outside the bank, the internal bureaucracy is just too much. And moreover, I think a bank is fundamentally not a place that can make good software. This is my plan. Write a report explaining in depth all the problems with their current system Explain why their software practices fail and generate a tremendous amount of error and waste. Use this as the basis for claiming the project must be developed externally. Write a high level development plan, including what resources I will require Hand 1,2,3 to my manager, hopefully he passes it up the chain. Worst case he fires me, but this isn't so bad. Convinced Executive decides to award my company a contract for the new system I have 8 years experience as a software contractor and have delivered my share of successful software products, but all working in-house for small/medium sized companies. When I read this over, I think I have a dynamite plan. But since this is the first time doing something this bold so I have my doubts. My question is, is this a good idea? If you think not, please spare no detail.

  • Maddening Linked List problem

    - by Mike
    This has been plaguing me for weeks. It's something really simple, I know it. Every time I print a singly linked list, it prints an address at the end of the list. #include <iostream> using namespace std; struct node { int info; node *link; }; node *before(node *head); node *after(node *head); void middle(node *head, node *ptr); void reversep(node *head, node *ptr); node *head, *ptr, *newnode; int main() { head = NULL; ptr = NULL; newnode = new node; head = newnode; for(int c1=1;c1<11;c1++) { newnode->info = c1; ptr = newnode; newnode = new node; ptr->link = newnode; ptr = ptr->link; } ptr->link=NULL; head = before(head); head = after(head); middle(head, ptr); //reversep(head, ptr); ptr = head; cout<<ptr->info<<endl; while(ptr->link!=NULL) { ptr=ptr->link; cout<<ptr->info<<endl; } system("Pause"); return 0; } node *before(node *head) { node *befnode; befnode = new node; cout<<"What should go before the list?"<<endl; cin>>befnode->info; befnode->link = head; head = befnode; return head; } node *after(node *head) { node *afnode, *ptr2; afnode = new node; ptr2 = head; cout<<"What should go after the list?"<<endl; cin>>afnode->info; ptr2 = afnode; afnode->link=NULL; ptr2 = head; return ptr2; } void middle(node *head, node *ptr) { int c1 = 0, c2 = 0; node *temp, *midnode; ptr = head; while(ptr->link->link!=NULL) { ptr=ptr->link; c1++; } c1/=2; c1-=1; ptr = head; while(c2<c1) { ptr=ptr->link; c2++; } midnode = new node; cout<<"What should go in the middle of the list?"<<endl; cin>>midnode->info; cout<<endl; temp=ptr->link; ptr->link=midnode; midnode->link=temp; } void reversep(node *head, node *ptr) { node *last, *ptr2; ptr=head; ptr2=head; while(ptr->link!=NULL) ptr = ptr->link; last = ptr; cout<<last->info; while(ptr!=head) { while(ptr2->link!=ptr) ptr2=ptr2->link; ptr = ptr2; cout<<ptr->info; } } I'll admit that this is class work, but even the professor can't figure it out, and says that its probably something insignificant that we're overlooking, but I can't put my mind to rest until I find out what it is.

  • Oversized Qt Fonts on OSX

    - by Mike Arthur
    Why does Qt on OSX appear to default to overly large fonts? Even when you select the same font size manually the fonts appear slightly bigger. Does Qt on OSX use a different font rendering to OSX? Does this improve if you use Qt for Cocoa? In addition, is there a qtconfig tool or equivalent to globally set the font settings for all Qt applications? Thanks!

  • portlet-mvc 3.0 + maven for websphere portlet: examples?

    - by Mike
    I'm trying to develop a websphere portal portlet using java, maven and spring-portlet-mvc 3.0.2.RELEASE but so far I'm not having a lot of luck. The problem that I'm having is that a lot of the tutorials are either outdated, incorrect, contradict eachother or a combination of all the above. Also I have to use RAD but the tutorials also contradict eachother, logically I'd think you'd choose new portlet project, but http://www.ibm.com/developerworks/websphere/library/techarticles/0802_patil-pt1/0802_patil-pt1.html says to use a dynamic webproject. So I was wondering if anyone had a nice example/good tutorial.

  • spring add default value to form:select

    - by Mike
    I'm developing a spring application, now I've added a dropdownlist to one of my jsp pages using: <form:select multiple="single" path="users[y.count-1].X" items="${Y}" itemValue="id" itemLabel="name"/> Now I'd like to add the default value "Nothing selected", however I can't seem to find how to do this. I've tried: <form:select multiple="single" path="users[y.count-1].X" items="${Y}" itemValue="id" itemLabel="name"> <form:option value="Nothing selected" /> </form:select> But "Nothing selected" isn't displayed in my dropdownlist.

  • NSMutableUrlRequest eats plus signs

    - by Mike
    I create NSMutableUrlRequest for sending data to server, add all necessary fields to it and then add the string for sending like this: [theRequest setHTTPBody:[postString dataUsingEncoding: NSUTF8StringEncoding]]; postString is a usual NSString. The problem is, when I receive this request at the server, all the plus (+) signs disappear from the http body. So if I had "abcde+fghj" on iPhone, I get "abcde fghj" on the server". Can this be some encoding problem from using dataUsingEncoding: NSUTF8StringEncoding? Or some NSMutableUrlRequest stripping feature? What can I do to make it stop stripping plus signs? I need to receive UTF8 strings at the server side.

  • How can I set up .Net unhanlded exception handling in a windows service?

    - by Mike Pateras
    protected override void OnStart(string[] args) { AppDomain.CurrentDomain.UnhandledException += new UnhandledExceptionEventHandler(CurrentDomain_UnhandledException); Thread.Sleep(10000); throw new Exception(); } void CurrentDomain_UnhandledException(object sender, UnhandledExceptionEventArgs e) { } I attached a debugger to the above code in my windows service, setting a breakpoint in CurrentDomain_UnhandledException, but it was never hit. The exception pops up saying that it is unhandled, and then the service stops. I even tried putting some code in the event handler, in case it was getting optimized away. Is this not the proper way to set up unhandled exception handling in a windows service?

  • accepts_nested_attributes_for ignore blank values

    - by Mike
    i have class Profile has_many :favorite_books, :dependent => :destroy has_many :favorite_quotes, :dependent => :destroy accepts_nested_attributes_for :favorite_books, :allow_destroy => true accepts_nested_attributes_for :favorite_quotes, :allow_destroy => true end I have a dynamic form where you press '+' to add new textareas for creating new favorites. What i want to do is ignore the blank ones, I find this harder to sort through in the update controller than a non nested attribute. What i have temporarily is a hack in the after_save callback deleting the empty records. Whats the most rails way to ignore these blank objects? I dont want validation and errors, just a silent deletion/ignore.

  • Perl, share package variable without Export

    - by Mike
    I'm creating a group of Perl scripts, and I would like to have one package store a group of constants. I don't want to export them using Exporter because there will be quite a few and I don't want to pollute the namespace. Since there will be so many, I don't want to require the user to be forced to manually specify which they will be using. I think the best way to just use the packagename::var syntax, however it doesn't seem to be working as I expect it to. I illustrate this problem in the below code This is settings.pm, the module that will hold the global settings #!/usr/bin/perl #settings.pm use strict; use warnings; package settings; our $foo="hello world"; 1; Below is the main script #!/usr/bin/perl #script.pl use strict; use warnings; use settings; print settings::$foo; It gives this error message instead or printing hello world Bad name after settings:: at ./script.pl line 8.

  • Batch Geocoding with Garmin Mapsource

    - by Mike Trader
    Please Note: I AM NOT LOOKING FOR AN ALTERNATIVE SOLUTION I lost track of this effort years ago but have need to geocode thousands of addresses nightly. I must use the very accurate database sitting on the machine, installed when the Nuvi map update installed Mapsource. When I contacted Garmin years ago, they expressed an interest in providing an API for this, but then I heard nothing and did not follow up. Their database is provided by navtec? I believe. Anyone have experience with that format? I posted on the Garmin Developer forum a while ago, but its a little lethargic over there :) Has anyone done this? Does anyone know how it might be done without an API; meaning database structure and calls? I'll take a solution in any language. Added: Garmin has expressed an interest in making this available to me. They just have not done it. I do not know the database format. I am NOT looking for an online solution or any other "alternative". This question is very specific. Contact Info: MikeTrader2 A T gmail D O T com Added: I offered a 400 pt bounty for this. Jeff Atwood then offered 400pts also. If you would like to see a solution to this, vote up the question and I will chase up Garmin and show there is interest in finally providing this. Please Note: I AM NOT LOOKING FOR AN ALTERNATIVE SOLUTION

  • In Perl, is a while loop generally faster than a for loop?

    - by Mike
    I've done a small experiment as will be shown below and it looks like that a while loop is faster than a for loop in Perl. But since the experiment was rather crude, and the subject might be a lot more complicated than it seems, I'd like to hear what you have to say about this. Thanks as always for any comments/suggestions :) In the following two small scripts, I've tried while and for loops separately to calcaulte the factorial of 100,000. The one that has the while loop took 57 minutes 17 seconds to finish while the for loop equivalent took 1 hour 7 minutes 54 seconds. Script that has while loop: use strict; use warnings; use bigint; my $now = time; my $n =shift; my $s=1; while(1){ $s *=$n; $n--; last if $n==2; } print $s*$n; $now = time - $now; printf("\n\nTotal running time: %02d:%02d:%02d\n\n", int($now / 3600), int(($now % 3600) / 60), int($now % 60)); Script that has for loop: use strict; use warnings; use bigint; my $now = time; my $n =shift; my $s=1; for (my $i=2; $i<=$n;$i++) { $s = $s*$i; } print $s; $now = time - $now; printf("\n\nTotal running time: %02d:%02d:%02d\n\n", int($now / 3600), int(($now % 3600) / 60), int($now % 60));

  • What do you use to keep notes as a developer?

    - by Mike Duncan
    Where as a developer do like to you keep your code snippets, links, checklists, final solutions to problems etc? I've fooled with Google Notebook, MS Onenote, TreePad, textfiles, and Evernote a bit (currently leaning toward Evernote). All have pros and cons but none seem to be really suited to developers. Is anyone super-happy with a collection / note system that's not just generic GTD, but with developer-centric utility?

  • Favorite Drupal tips or best practices?

    - by Mike Crittenden
    Just wondering what tips or tricks you guys might have to share. As always with posts like this, please only one tip per post so they can be voted on independently. I'll start: however you do your theming, you can use the mothership theme as a base theme for your theme to inherit from so that your markup will be a lot cleaner and less verbose.

  • Eclipse code template to insert a bookmark?

    - by Mike
    Eclipse has a nifty feature which allows you to define "templates" for code. I have created one to automatically put in a println and add a "TODO" comment. I'd like for this to also add a bookmark so I can easily find it again. (The codebase I am working with makes it unfeasible to use just the Task List to find what I need to do since there are a lot of TODOs laying around.) My current template is simply System.out.println("don't commit me!"); //TODO: fix this ${cursor}.

  • How do I get apache RewriteRule working correctly for a subdomain?

    - by mike
    I just setup a subdomain with the following RewriteCond: RewriteCond $1 !^search.php$ RewriteCond %{REQUEST_FILENAME} !-f RewriteRule ^/?([^/]+)$ search.php?q=$1 [L,NS] I'm using the same rewrite condition on my main domain and it works perfectly. However, when I set it up on the subdomain, it simply outputs "index.php" when going to http://sub.domain.com Every page on the subdomain outputs the page name in the body instead of processing the code, except for the search page, which appears to be working correctly. What can I do to correct this issue?

  • Processing incoming email

    - by Mike Schots
    How do I programmatically read an incoming email with .NET. I need a method to take the content of email message (in this case XML) on a POP server and read it into my application. Ideally this could be solved by: .NET code that I can run as a background task on my webserver to process the email. A service that can POST the contents of the email to my webserver. Although I'm open to other options. EDIT: Copied from the "non-answer": Currently, we're looking at using the email accounts our hosting company provides. Our own mail server could potentially be an option, but its something the we'd need to contact the host about.

  • TinyMCE or HTML5's contentEditable attribute?

    - by Mike
    I have always hated wysiwyg editors but most of the applications I develop they are necessary for our clients to edit their content. After trying out a few different ones I seemed to like tinyMCE the best. Although powerful and seems to generate fairly good HTML it is not without its issues. Recently I have been thinking about creating a custom wysiwyg that suits my needs perfectly taking advantage of the contentEditable attribute. Is this HTML5 feature ready? Will I have many cross browser issues? What are its limitations? I guess my question finally boils down to; Will it be worth throwing in the towel on 3rd party wysiwygs and moving to contentEditable regions?

  • Decimal Value is Zero when it should be 0.0x

    - by Mike Wills
    If this was previously talked about, I'm sorry, I had a hard time searching on this. I am calculating a depreciation rate. One portion of our calculation is 1/life in months. My table stores this data in a decimal field. I tried test = 1 / estimatedLife; but the result of the calculation of test (which is defined as a decimal) is 0. Say the estimated life is 36 months. So 1/36 should equal 0.02777778. Any thoughts of what I am doing wrong? BTW, I changed the test to a double and had the same result.

  • display of umlauts in firefox

    - by Mike D
    I was doing some web searching and found some strange things involving umlauts. For example if you do a google or yahoo search for the word "nther" you are likely to find things like G&#xfc;nther which I take to be Gunther with an umlaut over the u. Now my question is what if anything can I do to cause these characters to be properly displayed by Firefox under windows XP? An amazing thing is that I had to introduce spaces in the G & # etc string otherwise it was properly displayed here as u with umlaut!
