• Efficient most common suffix algorithm?

  - by taw

  I have a few GBs worth of strings, and for every prefix I want to find 10 most common suffixes. Is there an efficient algorithm for that? An obvious solution would be: Store sorted list of <string, count> pairs. Identify by binary search extent for prefix we're searching. Find 10 highest counts in this extent. Possibly precompute it for all short prefixes, so it doesn't ever need to look at large portion of data. I'm not sure if that would actually be efficient at all. Is there a better way I overlooked? Answers must be real time, but it can take as much preprocessing as necessary.

• c++ : list(vector) definition with array

  - by Meloun

  I have Class Email, there is parameter "bcc" in her construktor. Its actually list of emails for copies. There is no fixed number of these emails and later i have to have possibility to extend this list. //construktor prototype Email::Email(vector<string> bcc) So i want to use type vector or list for that and function push_back(). How can i make a new instance with bcc emails? I need actually declaration with definition for my list. I've found this definition with iterator for integer type: int myints[] = {16,2,77,29}; Email myEmail(vector<int> (myints, myints + sizeof(myints) / sizeof(int) )); , but its not very user friend and i need it with strings. Is there something like this? Email myEmail(vector<string> ("first","second","third"));

• C# 4.0: Can I use a Color as an optional parameter with a default value?

  - by DTown

  public void log(String msg, Color c = Color.black) { loggerText.ForeColor = c; loggerText.AppendText("\n" + msg); } This results in an error that c must be a compile-time constant. I've read up on this a little and most examples are dealing with strings and ints. I've figured out I can use the colorconverter class but I'm not sure it will be very efficient. Is there a way to just pass a basic color as an optional parameter? public void log(String msg, String c = "Black") { ColorConverter conv = new ColorConverter(); Color color = (Color)conv.ConvertFromString(c); loggerText.ForeColor = color; loggerText.AppendText("\n" + msg); }

• penetration of web 2.0 features amongst users?

  - by user151841

  I have a survey web-app that is public facing. I want to set up automated testing with Selenium, but selenium can't capture javascript alerts that we're currently using on the site. I'm thinking about changing our user-facing error notifications to some web 2.0 javascript library so that it is accessible to Selenium. However, I'm not sure how many of our users would be able to experience them properly. How backwards-compatible do I need to be in the present day? I have collected a database of actual user-agent strings of our users. I asked here how I could group them into meaningful data about what browsers our users are actually using.

• gcc options for fastest code

  - by rwallace

  I'm distributing a C++ program with a makefile for the Unix version, and I'm wondering what compiler options I should use to get the fastest possible code (it falls into the category of programs that can use all the computing power they can get and still come back for more), given that I don't know in advance what hardware, operating system or gcc version the user will have, and I want above all else to make sure it at least works correctly on every major Unix-like operating system. Thus far, I have g++ -O3 -Wno-write-strings, are there any other options I should add? On Windows, the Microsoft compiler has options for things like fast calling convention and link time code generation that are worth using, are there any equivalents on gcc? (I'm assuming it will default to 64-bit on a 64-bit platform, please correct me if that's not the case.)

• New to javascript, why is jQuery such a beast?

  - by gnucom

  Hey Everyone, I'm new to javascript (functional programming is okay for me, though) and I am wondering how jQuery got away with some of the design decisions they made. Is it just too much work to fix now or what? For instance, there seems use of strange symbols in strings when accessing elements in the DOM or weird function definitions for $, that are forcing me to check references every other time I want to get some basic data. Can someone point me to a learning source where I can learn all of these nuances of jQuery (jQuery's examples just don't cut it, they're too spread out)? Maybe someone has a super good reference site/pdf for jQuery? Thanks

• Set Caret position with JTextArea in JScrollPane

  - by Albinoswordfish

  Right now I have a JTextArea inside of a JScrollPane. For the current content it has both a vertical and horizontal scroll bar showing up. I'm trying to implement a search functionality where a user can search for a certain string and it will set the caret position to the first occurrence of that string. However it seems that JScrollPane only scrolls vertically when I set my caret position. So matching strings going off the JTextArea horizontally will completely get missed and the horizontal scroll bar won't scroll at all. I'm using the basic function setCaretPosition() for the JTextArea Does anybody have any idea why my JScrollPane isn't moving horizontally using setCaretPosition() Edit: It appears the horizontal scroll bar is scrolling but it moves so little that it's barely noticeable. I can only see the very first pixel of the character. Is there a way to have the scrollbar center (or as much as possible) to the caret position?

• Read a file address from a txt file using netbeans c

  - by Yadira Suazo

  Hi everybody. I`m having problems reading a file address from a txt file. The information seems to be corrupted when I watch it in the debugger. The code is FILE *parch; const char * vectorparch[50]; //array with 50 file paths parch = fopen("/home/irmay/NetBeansProjects/neurona/patrones/patrones.txt", "r"); for(j=0;j<50;j++){ fread ( vectorparch, sizeof ( char ), 50, parch ); propagar(vectorparch[j]); } fclose(parch); The file with paths has 50 strings is like this: "/home/irmay/NetBeansProjects/neurona/patrones/10_0.txt","/home/..." The function propagar is declared void propagar (const char * arch1) Thank you.

• loading xml slow down my site

  - by Ayrton

  Hi is it possible that loading an xml is slowing down my site? I've written this little function in php to iterate over an array of Strings to calculate the total amount of my followers function getFeedCount() { foreach ($array as $value) { $xml = simplexml_load_file("http://api.feedburner.com/awareness/1.0/GetFeedData?uri=$value") or die ("Unable to load XML file!"); $circulation += $xml->feed->entry['circulation']; } return $circulation; } the array is about 10 items big and since I started using it, it really slowed down my site. What could I do fix this issue.

• How do you get the logical xor of two variables in Python?

  - by Zach Hirsch

  How do you get the logical xor of two variables in Python? For example, I have two variables that I expect to be strings. I want to test that only one of them contains a True value (is not None or the empty string): str1 = raw_input("Enter string one:") str2 = raw_input("Enter string two:") if logical_xor(str1, str2): print "ok" else: print "bad" The ^ operator seems to be bitwise, and not defined on all objects: >>> 1 ^ 1 0 >>> 2 ^ 1 3 >>> "abc" ^ "" Traceback (most recent call last): File "<stdin>", line 1, in <module> TypeError: unsupported operand type(s) for ^: 'str' and 'str'

• Matching an IP address with an IP range?

  - by Legend

  I have a MySQL table setup as follows: +---------------+-------------+------+-----+---------+----------------+ | Field | Type | Null | Key | Default | Extra | +---------------+-------------+------+-----+---------+----------------+ | ipaddress_s | varchar(15) | YES | MUL | NULL | | | ipaddress_e | varchar(16) | YES | | NULL | | +---------------+-------------+------+-----+---------+----------------+ where, ipaddress_s and ipaddress_e look something like: 4.100.159.0-4.100.159.255 Now is there a way I can actually get the row that contains a given IP address? For instance, given the IP address: "4.100.159.5", I want the above row to be returned. So I am trying for a query that looks something like this (but of course this is wrong because in the following I am considering IPs as strings): SELECT * FROM ranges WHERE ipaddress_s<"4.100.159.5" AND ipaddress_e>"4.100.159.5" Any suggestions?

• best way to output a full precision double into a text file

  - by flevine100

  Hi, I need to use an existing text file to store some very precise values. When read back in, the numbers essentially need to be exactly equivalent to the ones that were originally written. Now, a normal person would use a binary file... for a number of reasons, that's not possible in this case. So... do any of you have a good way of encoding a double as a string of characters (aside from increasing the precision). My first thought was to cast the double to a char[] and write out the chars. I don't think that's going to work because some of the characters are not visible, produce sounds, and even terminate strings ('\0'... I'm talkin to you!) Thoughts?

• ChoiceFormat.setChoices confusion about format parameter type and documentation

  - by polygenelubricants

  From the java.text.ChoiceFormat API: setChoices(double[] limits, String[] formats): Set the choices to be used in formatting. Parameters: limits - contains [...] formats - are the formats you want to use for each limit. They can be either Format objects or Strings. When formatting with object Y, if the object is a NumberFormat, then ((NumberFormat) Y).format(X) is called. Otherwise Y.toString() is called. I'm having difficulties understanding the documentation for the formats parameter: how can you possibly pass a Format/NumberFormat object to setChoices if it's declared String[] formats? Note that interestingly, the getters counterpart of setChoices are declared as follows: double[] getLimits() Object[] getFormats() -- not String[]!!! Is this a bug in the API? Should the setter have been declared setChoices(double[], Object[]) instead, or am I not understanding how to use setChoices correctly?

  Hi, I wrote a little search script for a client, it works and words get highlited, BUT... Imagine this situation: search term: test found result: Hello this <a href="/news/this-is-a-test">is a test</a> In this example both 'test' in the href part and between the <a> tags get highlited, breaking the link. How could I prevent this? Edit: So this is what I need: A regex replace function that replaces all matched search strings EXCEPT the ones that are located inside a href attribute Greets, nick

• Extract multiple values from one column in MySql

  - by Neil

  I've noticed that MySql has an extensive search capacity, allowing both wildcards and regular expressions. However, I'm in somewhat in a bind since I'm trying to extract multiple values from a single string in my select query. For example, if I had the text "<span>Test</span> this <span>query</span>", perhaps using regular expressions I could find and extract values "Test" or "query", but in my case, I have potentially n such strings to extract. And since I can't define n columns in my select statement, that means I'm stuck. Is there anyway I could have a list of values (ideally separated by commas) of any text contained with span tags? In other words, if I ran this query, I would get "Test,query" as the value of spanlist: select <insert logic here> as spanlist from HtmlPages ...

• Kerning problems when drawing text character by character

  - by shekel

  I'm trying to draw strings character by character to add lighting effects to shapes composed of text. while (i != line.length()) { c = line.substring(i, i + 1); cWidth = g.getFontMetrics().stringWidth(c); g.drawString(c, xx += cWidth, yy); i++; } The problem is, the width of a character isn't the actual distance it's drawn from another character when those two characters are printed as a string. Is there any way to get the correct distance in graphics2d?

• Silverlight/WPF: Retreiving the size of a `UIElement` once it has been rendered on screen

  - by ondesertverge

  I have the following simple piece of code: var canvas = new Canvas(); foreach (var ztring in strings) { var textblock = new TextBlock(); textblock.Text = ztring; panel.Children.Add(textblock); textblock.Measure(infiniteSize); } At this point I would expect any of the size properties (Height/Width, ActualHeight/ActualWidth, DesiredSize, RenderSize) to give me the size of the textblock. None of them do. ActualHeight always gives 16.0 no matter what size font. ActualWidth changes according to the text length but not the font size. I change the font size on the parent container and not the TextBlock itself. I feel like I am missing some basic element of understanding the manipulation of silverlight elements from within the codebehind. The question is: how do I get the real actual pixel size of my TextBlock?

• How do I include extremely long literals in C++ source?

  - by BillyONeal

  Hello everyone :) I've got a bit of a problem. Essentially, I need to store a large list of whitelisted entries inside my program, and I'd like to include such a list directly -- I don't want to have to distribute other libraries and such, and I don't want to embed the strings into a Win32 resource, for a bunch of reasons I don't want to go into right now. I simply included my big whitelist in my .cpp file, and was presented with this error: 1>ServicesWhitelist.cpp(2807): fatal error C1091: compiler limit: string exceeds 65535 bytes in length The string itself is about twice this allowed limit by VC++. What's the best way to include such a large literal in a program?

• So, I guess I can't use "&&" in the Python if conditional. Any help?

  - by Sergio Tapia

  Here's my code: # F. front_back # Consider dividing a string into two halves. # If the length is even, the front and back halves are the same length. # If the length is odd, we'll say that the extra char goes in the front half. # e.g. 'abcde', the front half is 'abc', the back half 'de'. # Given 2 strings, a and b, return a string of the form # a-front + b-front + a-back + b-back def front_back(a, b): # +++your code here+++ if len(a) % 2 == 0 && len(b) % 2 == 0: return a[:(len(a)/2)] + b[:(len(b)/2)] + a[(len(a)/2):] + b[(len(b)/2):] else: #todo! Not yet done. :P return I'm getting an error in the IF conditional. What am I doing wrong?

• How to determine the end of an integer array when manipulating with integer pointer?

  - by AKN

  Here is the code: int myInt[] ={ 1, 2, 3, 4, 5 }; int *myIntPtr = &myInt[0]; while( *myIntPtr != NULL ) { cout<<*myIntPtr<<endl; myIntPtr++; } Output: 12345....<junks>.......... For Character array: (Since we have a NULL character at the end, no problem while iterating) char myChar[] ={ 'A', 'B', 'C', 'D', 'E', '\0' }; char *myCharPtr = &myChar[0]; while( *myCharPtr != NULL ) { cout<<*myCharPtr<<endl; myCharPtr++; } Output: ABCDE My question is since we say to add NULL character as end of the strings, we rule out such issues! If in case, it is rule to add 0 to the end of integer array, we could have avoided this problem. What say?

• Ruby string encoding problem

  - by John Prideaux

  I've looked at the other ruby/encoding related posts but haven't been able to figure out why the following is not working. Likely just because I'm dense, but here's the situation. Using Ruby 1.9 on windows. I have a set of CSV files that need some data appended to the end of each line. Whenever I run my script, the appended characters are gibberish. The input text appears to be IBM437 encoding, whereas my string I'm appending starts as US-ASCII. Nothing I've tried with respect to forcing encoding on the input strings or the append string seems to change the resultant output. I'm stumped. The current encoding version is simply the last that I tried. def append_salesperson(txt, salesperson) if txt.length > 2 return txt.chomp.force_encoding('US-ASCII') + %(, "", "", "#{salesperson}") end end salespeople = Hash[ "fname", "Record Manager"] outfile = File.open("ActData.csv", "w:US-ASCII") salespeople.each do | filename, recordManager | infile = File.open("#{filename}.txt") infile.each do |line| outfile.puts append_salesperson(line, recordManager) end infile.close end outfile.close

• Finding if all elements in a vector<string> are in a string

  - by devin

  I have a vector and I need to see if all the strings in that vector are substrings of another given string. eg vector<string> v; v.push_back("str1"); v.push_back("str2"); string s1 = "str1, str2, str3"; string s2 = "str1, str3"; Is there a way to get true from s1 and false from s2 without looping over the vector? Also, note that due to my environment, I can't use boost. I think if I had boost, I could do this.

• routing difficulty

  - by user281180

  Part of my application maps resources stored in a number of locations onto web URLs like this: http://servername/Issue.aspx/Details?issueID=1504/productId=2345 Is it possible to construct an MVC route that matches this so that I get the path in its entirety passed into my controller? Either as a single string or possibly as an params style array of strings.

• Scanner cuts off my String after about 2400 characters

  - by Ventrue

  I've got some very basic code like while (scan.hasNextLine()) { String temp = scan.nextLine(); System.out.println(temp); } where scan is a Scanner over a file. However, on one particular line, which is about 6k chars long, temp cuts out after something like 2470 characters. There's nothing special about when it cuts out; it's in the middle of the word "Australia." If I delete characters from the line, the place where it cuts out changes; e.g. if I delete characters 0-100 in the file then Scanner will get what was previously 100-2570. I've used Scanner for larger strings before. Any idea what could be going wrong?

• Identifying individual values in a text box using Flash

  - by Jamash1989

  I want to identify specific strings in a text box from user input to add to a score variable, like so - if (userWords.text == firstWord) { score = score + 1; } The example given adds 1 to the score, but if a user adds a space then a second word the text box views it as a whole and not individual words, resulting in no values added to the score variable. The problem lies with the whole text box being viewed as one entire string. Instead, I want to split it up so word1 will add 1 to the score, word2 will add 1 to the score, etc. I am ultra confused with this problem, so thank you to anyone that may help.
