• how to parse jquery ajax xhtml response?

  - by steve

  Sorry if this has been posted many times. But I've tried many variations and it still doesn't work. The HTML comes back from the jquery AJAX call fine and I am trying to remove the header and footers from the response using: // none of these work for me $("#content", data); $("#content", $(data)); $(data).find("#content").html() I've breakpoint the response to verify the #content exists by inspected $(data) and using alert to print out the data's text. I've also try using "body" or "a" as selectors, but it always come back as undefined. I've read in this post that you can't pull in the full XHTML document: http://stackoverflow.com/questions/1050333/jquery-ajax-parse-response-text. But I can't find the answer's quote anymore, maybe it's outdated? Has anyone ran into this problem? Many thanks, Steve

• Storing and comparing biometric information

  - by Chathuranga Chandrasekara

  I am not sure whether this is the best place to post this. But this is strongly related with programming so decided to put this here. In general we use biometrics in computer applications say for authentication. Lets get 2 examples finger prints and facial recognition. In those cases how we keep the information for comparison. As an example we can't keep a image and process it every time. So what are the methodologies we use to store/determine the similarity in such cases? Are there any special algorithms that designed for that purposes.? (Ex : To return a approximately equal value for a finger print of a certain person every time)

• PycURL RESUME_FROM

  - by excid3

  I can't seem to get the RESUME_FROM option to work. Here's some example code that I have been testing with: import os import pycurl import sys def progress(total, existing, upload_t, upload_d): try: frac = float(existing)/float(total) except: frac = 0 sys.stdout.write("\r%s %3i%%" % ("file", frac*100) ) url = "http://launchpad.net/keryx/stable/0.92/+download/keryx_0.92.4.tar.gz" filename = url.split("/")[-1].strip() def test(debug_type, debug_msg): print "debug(%d): %s" % (debug_type, debug_msg) c = pycurl.Curl() c.setopt(pycurl.URL, url) c.setopt(pycurl.FOLLOWLOCATION, 1) c.setopt(pycurl.MAXREDIRS, 5) # Setup writing if os.path.exists(filename): f = open(filename, "ab") c.setopt(pycurl.RESUME_FROM, os.path.getsize(filename)) else: f = open(filename, "wb") c.setopt(pycurl.WRITEDATA, f) #c.setopt(pycurl.VERBOSE, 1) c.setopt(pycurl.DEBUGFUNCTION, test) c.setopt(pycurl.NOPROGRESS, 0) c.setopt(pycurl.PROGRESSFUNCTION, progress) c.perform()

• gcc linking shared libraries with dependent libraries

  - by Geng

  I have a complicated project with multiple executable targets and multiple shared libraries. The shared libraries currently don't have their dependent shared libraries linked in, and the result is that linker arguments to build the executables are hideously long and hard to maintain. I'd like to add in the dependencies so the Makefiles become much cleaner. I want to add the following (example): gcc -shared -o libshared.so -lshared_dependent1 -lshared_dependent2 objfile1.o objfile2.o Is there a way to test if all the symbols in libshared.so will resolve based on that line? Is there a way to print out if any of the shared_dependent libraries specified were unnecessary? Thanks in advance.

• MS Access 2003 - VBA for altering a table after a "SELECT * INTO tblTemp FROM tblMain" statement

  - by Justin

  Hi. I use functions like the following to make temporary tables out of crosstabs queries. Function SQL_Tester() Dim sql As String If DCount("*", "MSysObjects", "[Name]='tblTemp'") Then DoCmd.DeleteObject acTable, "tblTemp" End If sql = "SELECT * INTO tblTemp from TblMain;" Debug.Print (sql) Set db = CurrentDb db.Execute (sql) End Function I do this so that I can then use more vba to take the temporary table to excel, use some of excel functionality (formulas and such) and then return the values to the original table (tblMain). Simple spot i am getting tripped up is that after the Select INTO statement I need to add a brand new additional column to that temporary table and I do not know how to do this: sql = "Create Table..." is like the only way i know how to do this and of course this doesn't work to well with the above approach because I can't create a table that has already been created after the fact, and I cannot create it before because the SELECT INTO statement approach will return a "table already exists" message. Any help? thanks guys!

• Python CGI on Amazon AWS EC2 micro-instance -- a how-to!

  - by user595585

  How can you make an EC2 micro instance serve CGI scripts from lighthttpd? For instance Python CGI? Well, it took half a day, but I have gotten Python cgi running on a free Amazon AWS EC2 micro-instance, using the lighttpd server. I think it will help my fellow noobs to put all the steps in one place. Armed with the simple steps below, it will take you only 15 minutes to set things up! My question for the more experienced users reading this is: Are there any security flaws in what I've done? (See file and directory permissions.) Step 1: Start your EC2 instance and ssh into it. [Obviously, you'll need to sign up for Amazon EC2 and save your key pairs to a *.pem file. I won't go over this, as Amazon tells you how to do it.] Sign into your AWS account and start your EC2 instance. The web has tutorials on doing this. Notice that default instance-size that Amazon presents to you is "small." This is not "micro" and so it will cost you money. Be sure to manually choose "micro." (Micro instances are free only for the first year...) Find the public DNS code for your running instance. To do this, click on the instance in the top pane of the dashboard and you'll eventually see the "Public DNS" field populated in the bottom pane. (You may need to fiddle a bit.) The Public DNS looks something like: ec2-174-129-110-23.compute-1.amazonaws.com Start your Unix console program. (On Max OS X, it's called Terminal, and lives in the Applications - Utilities folder.) cd to the directory on your desktop system that has your *.pem file containing your AWS keypairs. ssh to your EC2 instance using a command like: ssh -i <<your *.pem filename>> ec2-user@<< Public DNS address >> So, for me, this was: ssh -i amzn_ec2_keypair.pem [email protected] Your EC2 instance should let you in. Step 2: Download lighttpd to your EC2 instance. To install lighttpd, you will need root access on your EC2 instance. The problem is: Amazon will not let you sign in as root. (Not straightforwardly, at least.) But there is a workaround. Type this command: sudo /bin/bash The system prompt-character will change from $ to #. We won't exit from "sudo" until the very last step in this whole process. Install the lighttpd application (version 1.4.28-1.3.amzn1 for me): yum install lighttpd Install the FastCGI libraries for lighttpd (not needed, but why not?): yum install lighttpd-fastcgi Test that your server is working: /etc/init.d/lighttpd start Step 3: Let the outside world see your server. If you now tried to hit your server from the browser on your desktop, it would fail. The reason: By default, Amazon AWS does not open any ports to your EC2 instance. So, you have to open the ports manually. Go to your EC2 dashboard in your desktop's browser. Click on "Security Groups" in the left pane. One or more security groups will appear in the upper right pane. Choose the one that was assigned to your EC2 instance when you launched your instance. A table called "Allowed Connections" will appear in the lower right pane. A pop-up menu will let you choose "HTTP" as the connection method. The other values in that line of the table should be: tcp, 80, 80, 0.0.0.0/0 Now hit your EC2 instance's server from the desktop in your browser. Use the Public DNS address that you used earlier to SSH in. You should see the lighttpd generic web page. If you don't, I can't help you because I am such a noob. :-( Step 4: Configure lighttpd to serve CGI. Back in the console program, cd to the configuration directory for lighttpd: cd /etc/lighttpd To enable CGI, you want to uncomment one line in the < modules.conf file. (I could have enabled Fast CGI, but baby steps are best!) You can do this with the "ed" editor as follows: ed modules.conf /include "conf.d\/cgi.conf"/ s/#// w q Create the directory where CGI programs will live. (The /etc/lighttpd/lighttpd.conf file determines where this will be.) We'll create our directory in the default location, so we don't have to do any editing of configuration files: cd /var/www/lighttpd mkdir cgi-bin chmod 755 cgi-bin Almost there! Of course you need to put a test CGI program into the cgi-bin directory. Here is one: cd cgi-bin ed a #!/usr/bin/python print "Content-type: text/html\n\n" print "<html><body>Hello, pyworld.</body></html>" . w hellopyworld.py q chmod 655 hellopyworld.py Restart your lighttpd server: /etc/init.d/lighttpd restart Test your CGI program. In your desktop's browser, hit this URL, substituting your EC2 instance's public DNS address: http://<<Public DNS>>/cgi-bin/hellopyworld.py For me, this was: http://ec2-174-129-110-23.compute-1.amazonaws.com/cgi-bin/hellopyworld.py Step 5: That's it! Clean up, and give thanks! To exit from the "sudo /bin/bash" command given earlier, type: exit Acknowledgements: Heaps of thanks to: wiki.vpslink.com/Install_and_Configure_lighttpd www.cyberciti.biz/tips/lighttpd-howto-setup-cgi-bin-access-for-perl-programs.html aws.typepad.com/aws/2010/06/building-three-tier-architectures-with-security-groups.html Good luck, amigos! I apologize for the non-traditional nature of this "question" but I have gotten so much help from Stackoverflow that I was eager to give something back.

• Getting the uptime of a SunOS UNIX box in seconds only

  - by JF

  How do I determine the uptime on a SunOS UNIX box in seconds only? On Linux, I could simply cat /proc/uptime & take the first argument: cat /proc/uptime | awk '{print $1}' I'm trying to do the same on a SunOS UNIX box, but there is no /proc/uptime. There is an uptime command which presents the following output: $ uptime 12:13pm up 227 day(s), 15:14, 1 user, load average: 0.05, 0.05, 0.05 I don't really want to have to write code to convert the date into seconds only & I'm sure someone must have had this requirement before but I have been unable to find anything on the internet. Can anyone tell me how to get the uptime in just seconds? TIA

• F# performance in scientific computing

  - by aaa

  hello. I am curious as to how F# performance compares to C++ performance? I asked a similar question with regards to Java, and the impression I got was that Java is not suitable for heavy numbercrunching. I have read that F# is supposed to be more scalable and more performant, but how is this real-world performance compares to C++? specific questions about current implementation are: How well does it do floating-point? Does it allow vector instructions how friendly is it towards optimizing compilers? How big a memory foot print does it have? Does it allow fine-grained control over memory locality? does it have capacity for distributed memory processors, for example Cray? what features does it have that may be of interest to computational science where heavy number processing is involved? Are there actual scientific computing implementations that use it? Thanks

• Combinatorics, probability, dice

  - by TarGz

  A friend of mine asked: if I have two dice and I throw both of them, what is the most frequent sum (of the two dice' numbers)? I wrote a small script: from random import randrange d = dict((i, 0) for i in range(2, 13)) for i in xrange(100000): d[randrange(1, 7) + randrange(1, 7)] += 1 print d Which prints: 2: 2770, 3: 5547, 4: 8379, 5: 10972, 6: 13911, 7: 16610, 8: 14010, 9: 11138, 10: 8372, 11: 5545, 12: 2746 The question I have, why is 11 more frequent than 12? In both cases there is only one way (or two, if you count reverse too) how to get such sum (5 + 6, 6 + 6), so I expected the same probability..?

• Get seconds since epoch in any POSIX compliant shell

  - by mattbh

  I'd like to know if there's a way to get the number of seconds since the UNIX epoch in any POSIX compliant shell, without resorting to non-POSIX languages like perl, or using non-POSIX extensions like GNU awk's strftime function. Here are some solutions I've already ruled out... date +%s // Doesn't work on Solaris I've seen some shell scripts suggested before, which parse the output of date then derive seconds from the formatted gregorian calendar date, but they don't seem to take details like leap seconds into account. GNU awk has the strftime function, but this isn't available in standard awk. I could write a small C program which calls the time function, but the binary would be specific to a particular architecture. Is there a cross platform way to do this using only POSIX compliant tools? I'm tempted to give up and accept a dependency on perl, which is at least widely deployed. perl -e 'print time' // Cheating (non-POSIX), but should work on most platforms

• better way to pass by reference in Perl?

  - by JoelFan

  I am doing pass-by-reference like this: sub repl { local *line = \$_[0]; our $line; $line = "new value"; } sub doRepl { my $foo = "old value"; my ($replFunc) = @_; $replFunc->($foo); print $foo; # prints "new value"; } doRepl(\&repl); Is there a cleaner way of doing it? Prototypes don't work because I'm using a function reference (trust be that there's a good reason for using a function reference). I also don't want to use $_[0] everywhere in repl because it's ugly.

• What is a Perl regex for finding the first non-consecutively-repeating character in a string.

  - by DVK

  Your task, should you choose to accept it, is to write a Perl regular expression that for a given string, will return the first occurence of a character that is not consecutively duplicated. In other words, both preceded AND succeeded by characters different from itself (or start/end of string respectively). Example: IN: aabbcdecc OUT: c Please note that "not consecutively duplicated" does not mean "anywhere in the string". NOTE: it must be a pure regex expression. E.g. the solution that obviously comes to mind (clone the string, delete all the duplicates, and print the first remaining character) does not count, although it solves the problem. The question is inspired by my somewhat off-topic answer to this: http://stackoverflow.com/questions/2548606/perl-function-to-find-first-non-repeating-character-in-a-string

• Constructing dynamic columns from parameters in Sybase

  - by Chapax

  Hi, I'm trying to write a stored proc (SP) in Sybase. The SP takes 5 varchar parameters. Based on the parameters passed, I want to construct the column names to be selected from a particular table. The below works: DECLARE @TEST VARCHAR(50) SELECT @TEST = "country" --print @TEST execute("SELECT DISTINCT id_country AS id_level, Country AS nm_level FROM tempdb..tbl_books INNER JOIN (tbl_ch2_bespoke_report INNER JOIN tbl_ch2_bespoke_rpt_mapping ON tbl_ch2_bespoke_report.id_report = tbl_ch2_bespoke_rpt_mapping.id_report) ON id_" + @TEST + "= tbl_ch2_bespoke_rpt_mapping.id_pnl_level WHERE tbl_ch2_bespoke_report.id_report = 14") but gives me multiple results: 1 1 row(s) affected. id_level nm_level 1 4376 XYZ 2 4340 ABC I would like to however only obtain the 2nd result. Do I need to necessarily use dynamic SQL to achieve this? Many thanks for your help. --Chapax

• confused about python decorators

  - by nbv4

  I have a class that has an output() method which returns a matplotlib Figure instance. I have a decorator I wrote that takes that fig instance and turns it into a Django response object. My decorator looks like this: class plot_svg(object): def __init__(self, view): self.view = view def __call__(self, *args, **kwargs): print args, kwargs fig = self.view(*args, **kwargs) canvas=FigureCanvas(fig) response=HttpResponse(content_type='image/svg+xml') canvas.print_svg(response) return response and this is how it was being used: def as_avg(self): return plot_svg(self.output)() The only reason I has it that way instead of using the "@" syntax is because when I do it with the "@": @plot_svg def as_svg(self): return self.output() I get this error: as_svg() takes exactly 1 argument (0 given) I'm trying to 'fix' this by putting it in the "@" syntax but I can't figure out how to get it working. I'm thinking it has something to do with self not getting passed where it's supposed to...

• sprintf an LPCWSTR variable

  - by Julio

  Hello everyone. I'm trying to debug print an LPCWSTR string, but I get a problem during the sprintf push in the buffer, because it retrieve only the first character from the string. Here is the code: HANDLE WINAPI hookedCreateFileW(LPCWSTR lpFileName, DWORD dwDesiredAccess, DWORD dwShareMode, LPSECURITY_ATTRIBUTES lpSecurityAttributes, DWORD dwCreationDisposition, DWORD dwFlagsAndAttributes, HANDLE hTemplateFile) { char buffer[1024]; sprintf_s(buffer, 1024, "CreateFileW: %s", lpFileName); OutputDebugString(buffer); return trueCreateFileW(lpFileName, dwDesiredAccess, dwShareMode, lpSecurityAttributes, dwFlagsAndAttributes, dwCreationDisposition, hTemplateFile); } For example I get "CreateFileW: C" or "CreateFileW: \". How do I properly push it in the buffer? Thank you.

• How to use jQuery .each() - I get a value, but it's the wrong one

  - by Ankur

  I am returning a JSON object (as a String) through a servlet. The JSON object looks like this: {"3":"Martin Luther","30":"Boris Becker","32":"Joseph Goebels","19":"Leonardo Da Vinci","31":"Adolf Hitler"} My jQuery looks like this (the submission of data is correct because I get a proper looking result from the servlet): $.ajax( { type : "GET", url : "MyServlet", data : queryString + "count=" + variables, success : function(resultObj) { $.each(resultObj, function(key, value) { $("#resultCount").html(key+", "+value); }); } }); However when I try to print the results, that is the variables key and value, I get a number for the key but not a number from the JSONObject and an empty string instead of the value. Essentially the question is about how to "extract" the information from a JSON object.

• Chinese encoding issue while listing files

  - by Null Pointer

  I am running a Java application on a Solaris10 with Chinese. Now there are some files in a directory with chinese filenames. When I do files = new File(dir).list() where "dir" is the parent directory containing that chinese file, I get the result filename files[0] as ?????(some junk characters). Now the deal is that my programs file.encoding property is already set to GBK and I also do Charset.isSupported("GBK") and it returns true too. So where could be the problem. I am running out of ideas. NOTE: I am not trying to print the filename anywhere or copy the file or something. I am simply openeing a stream to it, something like below: files = new File(dir).list(); new FileInputStream(files[0]); Now this gives me a FileNotFoundExcpetion, so I debug just to find that value inside files[0] is "??????".

• Switching Timezones in Perl's Template::Toolkit plugin Template::Plugin::Date

  - by aidan

  I have a calendar on my website, generated in Perl using Template::Toolkit and Template::Plugin::Date. It highlights the current day. I achieve this by iterating through all the dates (as I print the calendar) and comparing against the current date. Something like this: [% IF cur_date == date.format(format = '%Y-%m-%d') %] ... [% END %] It all works well until someone in Australia looks at it. (They are in a different timezone to me and my server in the UK). What's the best way to get Template::Plugin::Date to use a different time zone? It accepts a 'locale' parameter, but AFAIK this is only used for formatting.

• Filtering MySQL query result according to a interval of timestamp

  - by celalo

  Let's say I have a very large MySQL table with a timestamp field. So I want to filter out some of the results not to have too many rows because I am going to print them. Let's say the timestamps are increasing as the number of rows increase and they are like every one minute on average. (Does not necessarily to be exactly once every minute, ex: 2010-06-07 03:55:14, 2010-06-07 03:56:23, 2010-06-07 03:57:01, 2010-06-07 03:57:51, 2010-06-07 03:59:21 ...) As I mentioned earlier I want to filter out some of the records, I do not have specific rule to do that, but I was thinking to filter out the rows according to the timestamp interval. After I achieve filtering I want to have a result set which has a certain amount of minutes between timestamps on average (ex: 2010-06-07 03:20:14, 2010-06-07 03:29:23, 2010-06-07 03:38:01, 2010-06-07 03:49:51, 2010-06-07 03:59:21 ...) Last but not least, the operation should not take incredible amount of time, I need this functionality to be almost fast as a normal select operation. Do you have any suggestions?

• Match multiline regex in file object

  - by williamx

  How can I extract the groups from this regex from a file object (data.txt)? import numpy as np import re import os ifile = open("data.txt",'r') # Regex pattern pattern = re.compile(r""" ^Time:(\d{2}:\d{2}:\d{2}) # Time: 12:34:56 at beginning of line \r{2} # Two carriage return \D+ # 1 or more non-digits storeU=(\d+\.\d+) \s uIx=(\d+) \s storeI=(-?\d+.\d+) \s iIx=(\d+) \s avgCI=(-?\d+.\d+) """, re.VERBOSE | re.MULTILINE) time = []; for line in ifile: match = re.search(pattern, line) if match: time.append(match.group(1)) The problem in the last part of the code, is that I iterate line by line, which obviously doesn't work with multiline regex. I have tried to use pattern.finditer(ifile) like this: for match in pattern.finditer(ifile): print match ... just to see if it works, but the finditer method requires a string or buffer. I have also tried this method, but can't get it to work matches = [m.groups() for m in pattern.finditer(ifile)] Any idea?
