  • What program should I write to use up the 3,472 minutes on my iPhone 3GS?

    - by billmaya
    Something slightly off-topic but bear with me. I've got an iPhone 3GS that I use only for development and over the months I've accumulated 3,472 rollover minutes (my primary phone is an Android G-1). It seems a shame to let these minutes go to "waste." What cool iPhone app would you like to see that uses these minutes up in a productive, interesting, and possibly cool way. I'll code whichever suggestion has the highest vote, providing it's not illegal and doesn't violate Apple's SDK, and release it for free on the AppStore.

  • What's the best editor/program for g++ in Linux?

    - by Phenom
    So far I've been using vi, but I'm wondering if there's something better to use in Linux. In Windows there's Visual C++, and I guess practically all C++ programmers in Windows use this these days. It has a lot of things in it to help the programmer. What about for Linux?

  • Senior programming 'guru' who can't program - should I find a different career?

    - by confess
    Background: According to my resume I'm supposed to be pretty good at programming. I've worked on a ton of big projects at big companies over many years. When I go for an interview and someone looks at my resume they immediately assume I really know what I'm talking about. I generally communicate well, present myself well, know the 'jargon' and know a lot about technology at a high level, which makes matters worse because after talking to me for a while an interviewer really believes that what my resume says is probably true. The Problem: The problem arises when someone asks me to code something. I choke. As a programmer I have almost no capacity to come up with creative solutions of my own. I can't think through solutions to a programming problem the way good programmers are usually able to. I read questions on StackOverflow and the answer is obvious to me after I read other people's answers but if I am the first person to look at a question with no hints from anyone else I usually don't know where to start. At work it's the same thing. I'm fine if I'm correcting other people's code. I can identify the source of a bug quicker than anyone I work with. But if you ask me to sit down and code up a new application from scratch I will spend ten times longer than programmers who are much more junior than me. Question: Now that I am looking for work this is raising its ugly head in interview situations and making me feel desperately that I'm in the wrong career. I don't know if this problem is incompetence, laziness or some combination of these. Does anyone have any ideas about what I might be dealing with - are there books or exercises that could help me with this basic problem?

  • How can I keep up to date on the latest web development standards?

    - by Structure
    First off, I know that this question begs the other question - should the latest web development standards be followed and further will they remain relevant? That aside, I am focused on GUI development, usability, etc. Front-end web development that utilizes XHTML, CSS, JavaScript, etc. I know there are many gurus and thought leaders out there but with my projects I simply do not always have time to follow them all and keep up with the latest development standards. However, this is obviously very important. So how can I keep myself up to date on the latest web development standards while maintaining productivity? Are there any specific groups or organizations to monitor for this? Best practices that one might follow?

  • Trouble recording unique regex output to array in perl

    - by Structure
    The goal of the following code sample is to read the contents of $target and assign all unique regex search results to an array. I have confirmed my regex statement works so I am simplifying that so as not to focus on it. When I execute the script I get a list of all the regex results, however, the results are not unique which leads me to believe that my manipulation of the array or my if (grep{$_ eq $1} @array) { check is causing a problem(s). #!/usr/bin/env perl $target = "string to search"; $inc = 0; $once = 1; while ($target =~ m/(regex)/g) { #While a regex result is returned if ($once) { #If $once is not equal to zero @array[$inc] = $1; #Set the first regex result equal to @array[0] $once = 0; #Set $once equal to zero so this is not executed more than once } else { if (grep{$_ eq $1 } @array ) { #From the second regex result, check to see if the result is already in the array #If so, do nothing } else { @array[$inc] = $1; #If it is not, then assign the regex search result to the next unused position in the array in any position. $inc++; #Increment to next unused array position. } } } print @array; exit 0;

  • Is this the correct way to build a Perl hash that utilizes arrays?

    - by Structure
    This is the first time I have manipulated hashes and arrays in this way -- and it is working. Basically, for every key there are multiple values that I want to record and then print out in the form "key -- value -- value -- val..." My code is as follows. I am surprised that it works, so concerned that it works "by mistake". Is this the correct way to accomplish this task, or is there a more efficient or appropriate method? while ($source =~ m/(regex)/g) { #Get all key names from source $listkey = $1; #Set current list key to the current regex result. $list{$listkey} = ++$i unless $list{$listkey}; #Add the key to the hash unless it already exists. $list{$listkey} = [] unless exists $list{$listkey}; #Add an array for the hash unless the hash already exists. while ($loopcount==0) { if ($ifcount==0) { $listvalue=result_of_some_function_using_list_key; #Get the first list value from the list key. $ifcount++; #Increment so we only get the first list value once. } else { $listvalue=result_of_some_function_using_list_value; #Update the last list value. } if ($listvalue) { #If the function returned a value... push @{$list{$listkey}}, $listvalue; #...then add the value to the hash array for the key. } else { #There are no more values and we need a new key. $listkey=0; #Reset variable. $domain=0; #Reset variable. $loopcount++; #Increment loop counter to exit loop. } } $ifcount=0; #Reset count variable so the next listvalue can be generated from the new key. $loopcount=0; #Reset count variable so another loop can begin for a new key. } foreach $listkey (keys %list) { #For each key in the hash. print "$listkey --> "; #Print the key. @values = @{$list{$listkey}}; #Reference the arrays of the hash. print join ' --> ', @values; #Print the values. print "\n"; #Print new line. }

  • Should I be using libraries if I'm trying to learn how to program?

    - by CodeJustin.com
    I have been programming "a lot" in the past few months and at first I was trying to find the "easyest" language. Fortunately I realized that it's not about the language, it's about learning HOW to code. I ran into the Stanford lectures online (programming methodology) and I watched them all (around 23 hours total) awhile ago. Then I got into Java ME and programmed about 28.47% of a mobile RPG game (only around 2k lines of code). I feel like I learned a lot from those two experiences compared to previous ones but now that I'm moving into flash/actionscript 3.0 development and I'm finding myself learning like I did when I first started with PHP. I'm not really getting whats under the hood kind of. I'm finding myself using libraries to speed up development time which doesn't seem like a bad thing BUT I personally do not know how to write the libraries myself off hand. So should I be coding everything myself or is it ok to use libraries when you don't even know how to code them?

  • How to trigger notification code TBN_TOOLBARCHANGE from inside c++ program?

    - by karikari
    Hi. How to trigger TBN_TOOLBARCHANGE from inside my c++ code? Is it the same as writing like this line below? SendMessage(m_hWndToolbar, TB_SETBUTTONINFO, m_buttonID, (LPARAM)(&inf)); Inside this project's code there is this line inside one the header file: BEGIN_MSG_MAP(CRebarHandler) NOTIFY_CODE_HANDLER(TBN_DROPDOWN, onNotifyDropDown) NOTIFY_CODE_HANDLER(TBN_TOOLBARCHANGE, onNotifyToolbarChange) NOTIFY_CODE_HANDLER(NM_CUSTOMDRAW, onNotifyCustomDraw) NOTIFY_CODE_HANDLER(TBN_ENDADJUST, onNotifyEndAdjust) MESSAGE_HANDLER(WM_SETREDRAW, onSetRedraw) END_MSG_MAP() It has already defined that for each TBN_TOOLBARCHANGE call, it will trigger the function onNotifyToolbarChange. For this example, it is triggered by IE. Inside my code, I need to trigger that particular function. And before that I need to trigger the TBN_TOOLBARCHANGE`. I just want to know how can it be done inside code, for example under a conditional statement.

  • How do you create a program that will ask the user to enter 3 numbers that would display the largest

    - by lobosagwan
    int numbers; int largestNum = 0; Console.WriteLine("Enter numbers : "); numbers=int.Parse(Console.ReadLine()); numbers = 0; for (int i = 0; i < 3; i++) { if (numbers[i] > largestNum) } Console.WriteLine("The largest number is : {0}", largestNum); Console.ReadLine(); this is a similar code, the problem is how to ask the user to enter 3 numbers and display the largest number.

  • Possible to push a hash value only if it is unique?

    - by Structure
    In the example code below, assuming that the value $keyvalue is constantly changing, I am attempting to use a single line (or something similarly contained) to test and see if the current $keyvalue already exists. If it does, then do nothing. If it does not, then push it. This line would reside within a while statement which is why it needs to be contained within a few lines. Preserving order does not matter as long as there are no duplicate values. my $key = "numbers"; my $keyvalue = 1; my %hash = ($key => '1'); push (@{$hash{$key}}, $keyvalue) unless exists $hash{$key}; I am not getting any errors with use strict; use warnings;, but at the same time this is not working. In the example above, I would expect that since the default value is 1 that the $keyvalue would not be pushed as it is also 1. Perhaps I have gotten myself all turned around... Are there adjustments to get this to work or any alternatives that can be used instead to accomplish the same thing?

  • How can I write output to a new external file with Perl?

    - by Structure
    Maybe I am searching with the wrong keywords or this is a very basic question but I cannot find the answer to my question. I am having trouble writing the result of my whois command to a new external file. My code is below. It takes $readfilename, which is a file name which has a list of IPs, and $writefilename, which is the destination file for output. Both are user-specified. For my tests, $readfilename contains three IP addresses on three separate lines so there should be three separate whois results in the user specified output file. if ($readfilename) { open (my $inputfile, "<", $readfilename) || die "\n Cannot open the specified file. Please double check your file name and path.\n\n"; open (my $outputfile, ">", $writefilename) || die "\n Could not create write file.\n\n"; while (<$inputfile>) { my $iplookupresult = `whois $_`; print $outputfile $iplookupresult; } close $outputfile; close $inputfile; } I can execute this script and end up with a new external file, but over half of the file has binary garbage data (running on CentOS) and only one (or a portion of one) of the whois lookups is readable. I have no idea how half of my file is ending up binary... but my approach must be incorrect. Is there a better way to achieve the same result?
