  • can this code be shortened or improved?

    - by user2816683
    Can this be shortened/improved? I'm trying to make a password checker in python. Could the if's be put into a for loop? And if so, how? pw = input("Enter password to test: ") caps = sum(1 for c in pw if c.isupper()) lower = sum(1 for c in pw if c.islower()) nums = sum(1 for c in pw if c.isnumeric()) scr = ['weak', 'medium', 'strong'] r = [caps, lower, nums] if len(pw) < 6: print("too short") elif len(pw) > 12: print("too long") if caps >= 1: if lower >= 1: if nums >= 1: print(scr[2]) elif nums < 1: print("your password is " + scr[1]) elif lower < 1: print("your password strength is " + scr[0]) elif caps < 1: print("your password strength is " + scr[1]) Thanks for any suggestions :D

  • dabbledb + iPhone

    - by user193545
    I have been using DabbbleDB online database for storing/retrieving values for one of my iPhone applications. I am using their JSON response for retrieving the records. The problem that I am facing is that if there are a large number of records in the database, it takes a long time to get the response from the server and then to parse the JSON response. Instead I would like to to get a set of records at a time and run a loop to fetch all the records in background. I do not know whether we can query for a set of records at a time from online databases like DabbleDB. Anybody having an idea, please help.

  • Outputting audio stream into microphone

    - by Brap
    Hey everyone. Is there a way of outputting audio from my program and redirecting that stream to the system's microphone input 'layer'? I understand this might require some low-level calls being 'Pinvoked', but are there any articles that might help me. For example, if I was to run the output audio stream of my application into Window's Sound Recorder program, it would think that the audio is coming from a microphone and thus record that. I don't want to record a stream, just output it to the device's micrphone input. Thanks for any ideas.

    I create a UITableView with custom UITableViewCell,this is how i create the cell in cellForRowAtIndexPath: static NSString *CellIdentifier = @"SongsCell"; SongsCell *cell = (SongsCell*)[tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (cell == nil){ UIViewController *vc = [[[UIViewController alloc] initWithNibName:@"SongsCell" bundle:nil] autorelease]; cell = (SongsCell *) vc.view; } now i want to get all cells in the table info (parameter from cell) when a button pressed: for (int i = 0; i < [songTable numberOfRowsInSection:0]; i++) { NSIndexPath *indexPath = [NSIndexPath indexPathForRow:i inSection:0]; UITableViewCell *cell = [songTable cellForRowAtIndexPath:indexPath]; } Now i have a problem that this loop give me for cell a nil for all the cell that currently not seen in the table.

  • Putting a variable inside a string (python)

    - by Gish
    Hi I am quite new to python and this is probably quite a basic question but the help would be much appreciated. I would like to put an int within a string. This is what I am doing at the moment.. end = smooth(data,window_len=40) plot.plot(time[0:len(end)],end) plot.savefig('hanning(40).pdf') #problem line I have to run the program for several different numbers instead of the two 40's. So I'd like to do a loop but inserting the variable like this doesn't work: plot.savefig('hanning',num,'.pdf') Thanks!

  • for (Object object : list) [java] construction

    - by EugeneP
    My question, is, whether the sequence of elements picked from a list will always be the same, is this construction behaviour is deterministic for java "List"s - descendants of java.util.List 2) question, if I use for(Object o: list) construction and inside the loop's body increment a variable, will it be the index of list's elements? So, how it goes through list's elements, from 0 to size()-1 or chaotically? List.get(i) will always return this element? 3) question ( I suppose for the 2-nd question the answer will be negative, so:) for (int i=0; i < list.size(); i++) { } is the best way if I need to save the index of an element and later get it back from a list by its id?

  • Quickest and most efficient method to search top 3 numbers?

    - by Donal Rafferty
    I currently have an array of around 8 - 10 numbers that changes on a periodic basis. So around every 5 - 10 seconds the numbers get updated. I need to get the top 3 numbers in the array every 10 seconds. This is all done on a mobile device. At the minute I iterate through the array 3 times and each time I take out the three highest numbers and place them in three previously declared variables. My question is what should I look to do to increase speed and efficiency in this instance?

  • Picking photo from Photochooser or holding hardware back button cause active timers ring

    - by Nznoonee
    This is very strange problem, and all the people I had asked to confirm it said that it takes place. I have a Threading.Timer instance which fires every 15 minutes. And if I call the PhotoChooser view and then select a photo from it, when going back to the calling page my application calls that timer's callback! I tried different timers either it be Timer from Threading namespace or Dispatcher timer. The same happens when being in my app I hold the back button of my device and then choose the app from the list. My application is as plain as it can be - the timer with a callback and method calling PhotoChooser. Could anyone help with solution or workaround please?

  • What Android version to target?

    - by Richard Eng
    I'm about to write my first Android app. It's a fairly basic app that doesn't use any special features beyond being able to schedule notifications and read/write image files to the device's local storage. Reaching the broadest audience is my top priority. If I target Android 1.5, is the app guaranteed to run fine all the way up to ICS? Should I target Android 2.1, which seems to be the new baseline for common phones in use? Since the app is fairly basic, if I target ICS, would it run on versions going all the way back to 2.1? Maybe this is a stupid question.

  • read integers from a file into a vector in C++

    - by user2922063
    I am trying to read an unknown number of double values stored on separate lines from a text file into a vector called rainfall. My code won't compile; I am getting the error no match for 'operator>>' in 'inputFile >> rainfall' for the while loop line. I understand how to read in from a file into an array, but we are required to use vectors for this project and I'm not getting it. I appreciate any tips you can give on my partial code below. vector<double> rainfall; // a vector to hold rainfall data // open file ifstream inputFile("/home/shared/data4.txt"); // test file open if (inputFile) { int count = 0; // count number of items in the file // read the elements in the file into a vector while ( inputFile >> rainfall ) { rainfall.push_back(count); ++count; } // close the file

  • Is there a limitation to the length of the query in mysql?

    - by Bakhtiyor
    I am asking this question because I need to know this limitation as I am generating SELECT query in my PHP script and the part of WHERE in this query is generated inside the loop. Precisely it looks like this $query="SELECT field_names FROM table_name WHERE "; $condition="metadata like \"%$uol_metadata_arr[0]%\" "; for($i=1; $i<count($uol_metadata_arr); $i++){ $condition.=" OR metadata like \"%$uol_metadata_arr[$i]%\" "; } $query.=$condition; $result=mysql_query($query); So, that's why I need to know how long my $query string can be, because the array *$uol_metadata_arr* could contain many items.

  • $.each - wait for jSON request before proceeding

    - by GaaayLooord
    I have an issue with the below code: the jQuery.each is speeding on without waiting for the JSON request to finish. As a result, the 'thisVariationID' and 'thisOrderID' variables are being reset by the latest iteration of a loop before they can be used in the slower getJSON function. Is there a way to make each iteration of the the .each wait until completion of the getJSON request and callback function before moving on to the next iteration? $.each($('.checkStatus'), function(){ thisVariationID = $(this).attr('data-id'); thisOrderID = $(this).attr('id'); $.getJSON(jsonURL+'?orderID='+thisOrderID+'&variationID='+thisVariationID+'&callback=?', function(data){ if (data.response = 'success'){ //show the tick. allow the booking to go through $('#loadingSML'+thisVariationID).hide(); $('#tick'+thisVariationID).show(); }else{ //show the cross. Do not allow the booking to be made $('#loadingSML'+thisVariationID).hide(); $('#cross'+thisVariationID).hide(); $('#unableToReserveError').slideDown(); //disable the form $('#OrderForm_OrderForm input').attr('disabled','disabled'); } }) })

  • What are some Coldfusion (mx7 and greater) "Gotchas" that I should know about?

    - by jakeonrails
    I just spent half the day troubleshooting what is apparently a rather famous gotcha for Coldfusion MX7 and below: The nested query loop bug: Where you are required to reference the current_row of the outer query or else you will only see the first record. For example: <cfloop query="outer"> <cfloop query="innner"> <p>#outer.field#</p><!--- this won't work, you'll only get the first row ---> <p>#outer.field[current_row]#</p><!--- you must do this instead ---> </cfloop> </cfloop> Are there any other ways in which ColdFusion does not work in the obvious way?

  • Can someone please clarify the Birthday Effect for me?

    - by Mark
    Please help interpret the Birthday effect as described in Wikipedia: A birthday attack works as follows: Pick any message m and compute h(m). Update list L. Check if h(m) is in the list L. if (h(m),m) is already in L, a colliding message pair has been found. else save the pair (h(m),m) in the list L and go back to step 1. From the birthday paradox we know that we can expect to find a matching entry, after performing about 2^(n/2) hash evaluations. Does the above mean 2^(n/2) iterations through the above entire loop (i.e. 2^(n/2) returns to step 1), OR does it mean 2^(n/2) comparisons to individual items already in L.

    My app's icon includes some text. So I want to change language of the text by language or country. There is a post which says localizing app icon is not supported: http://useyourloaf.com/blog/2010/12/16/localizing-iphone-app-icon-is-not-supported.html But it was posted in December 2010, one and half years ago from now. Is it still not possible to change icon of app by language? Localizing both icon of app on device and icon on App Store are not supported? Or localizing icon only on App Store is possible?

  • Select_related() backwards relation - auto model population

    - by Nick
    Hi. If I have the following model: class Contact(models.Model) name = models.CharField(max_length=100) ... class ContactAddress(models.Model) line1 = models.CharField(max_length=100) line2 = models.CharField(max_length=100) ... contact = models.ForeignKey(Contact) I now want to grab all Contacts and for the address to be auto populated. What would be the best way to do this? The only way I have found so far is to filter out the Contacts I want and loop around each contact and assign this to Contact.addresses. I then use this for outputting each Contacts address within a template. Is there a better way of doing this? Select_related() almost does what I want, but doesn't seem to be able to work in the opposite direction. Thanks in advance for your help on this one!

Thanks. orig = csv.reader(open("googlel.csv", "rb"), delimiter = ';') goodrows = [] for feed in gotfeeds: for link,comments in feed.items(): for row in orig: print link if link in row[1]: row.append(comments) goodrows.append(row)

  • What is the right way to modify a wordpress query in a plugin?

    - by starepod
    Basically i am playing with a plugin that allows future-dated posts on archive pages. My question is broader than this specific functionality, but everyone likes some context. I have my head around many of the plugin development concepts, but must be missing something very basic. I can successfully rewrite a query that gives me the results i want like this: function modify_where( $where ) { global $wp_query; // define $year, $cat, etc if( is_archive() ) { $where = " AND YEAR(wp_posts.post_date)='".$year."' AND wp_term_taxonomy.taxonomy = 'category' AND wp_term_taxonomy.term_id IN ('".$cat."') AND wp_posts.post_type = 'post' AND (wp_posts.post_status = 'publish' OR wp_posts.post_status = 'future')"; } return $where; } add_filter('posts_where', 'catCal_where' ); However, if i attempt to create a new WP_Query('different_query_stuff') after the main loop the new query uses the same WHERE statement outlined above. The question is : What am I missing? Thanks.
