• Add mask to input

  - by Lodewijk Wensveen

  I'm trying to achieve the seemingly impossible task of adding an mask to a input field. I have the following code: function addActivationCode(){ newRow = jQuery("div.activationcode:last-child").clone(); newRow.insertAfter(jQuery("div.activationcode:last-child")); newRow.attr("id", "coderow-" + Math.round(Math.random() * 10000)); newRow.find("input").val(""); find("input").mask("9999-9999-9999-9999"); newRow.find("a.coderemove").attr("onclick", "removeActivationCode('" + newRow.attr("id") + "'); return false;"); } function removeActivationCode(id){ jQuery("div#" + id).remove(); } Now I to get the .mask working on my input fields, so far I've only got it working on the new row I'm making and not on the original one. Can anyone help me out?

• compare previous ENCRYPT() call with new ENCRYPT() call mysql

  - by contagious

  I'm storing a string in mysql with the ENCRYPT() function. I want to fetch a row where that string is matched, but the new ENCRYPT() call gives me a different value, so they never match. This is expected as i'm not (and can't) give it a consistent salt: http://dev.mysql.com/doc/refman/5.0/en/encryption-functions.html#function_encrypt If no salt argument is given, a random value is used. This is the query i'm running that returns empty: SELECT * FROM `table` WHERE ENCRYPT('string') = `enc_string` I know this is possible because this is used by a 3rd party app, but I can't find their query where they do this. Is there a way to force ENCRYPT to use the previous salt, or predict it?

• Compilier optimization of repeated accessor calls C#

  - by apocalypse9

  I've found recently that for some types of financial calculations that the following pattern is much easier to follow and test especially in situations where we may need to get numbers from various stages of the computation. public class nonsensical_calculator { ... double _rate; int _term; int _days; double monthlyRate { get { return _rate / 12; }} public double days { get { return (1 - i); }} double ar { get { return (1+ days) /(monthlyRate * days) double bleh { get { return Math.Pow(ar - days, _term) public double raar { get { return bleh * ar/2 * ar / days; }} .... } Obviously this often results in multiple calls to the same accessor within a given formula. I was curious as to whether or not the compiler is smart enough to optimize away these repeated calls with no intervening change in state, or whether this style is causing a decent performance hit. Further reading suggestions are always appreciated

• Downgrading to pyobjc 2.0 from pyobjc 2.2

  - by maxdj

  I accidentally installed pyobjc 2.2 with easy-install pyobjc, and it's causing problems: When I try to import it I get the error Incompatible library version: _objc.so requires version 10.0.0 or later, but libxml2.2.dylib provides version 9.0.0 I'm not interested in fixing that though, all I want is my pyobjc 2.0 back. I've tried removing pyobjc 2.2 and reinstalling python, and I've tried building 2.0 from the svn trunk (I get the error lipo: can't figure out the architecture of [random filename].out) I imagine there must be a good way of doing this but it escapes me. Any insight would be appreciated. Edit: Python 2.6 and OSX 10.5

• Video Synthesis - Making waves, pattern, gradients...

  - by Nathan

  I'm writing a program to generate some trippy visuals. My code paints each pixel with a random blue value which loops at 0.04 second intervals. for (y = 0; y < 5.5; y += 0.2) { for (x = 0; x < 7.5; x += 0.2) { b = rand() / ((double) RAND_MAX); setPixelColor(x,y,r,g,b); } } I'd like to do more than just make blue noise... but my maths is a bit rusty, and Google isn't helping me much today, so it would be great if you could share anything you know about making waves, patterns, gradient animations, etc or links to such material.

• problem plotting on logscale in matplotlib in python

  - by user248237

  I am trying to plot the following numbers on a log scale as a scatter plot in matplotlib. Both the quantities on the x and y axes have very different scales, and one of the variables has a huge dynamic range (nearly 0 to 12 million roughly) while the other is between nearly 0 and 2. I think it might be good to plot both on a log scale. I tried the following, for a subset of the values of the two variables: fig = plt.figure(figsize(8, 8)) ax = fig.add_subplot(1, 1, 1) ax.set_yscale('log') ax.set_xscale('log') plt.scatter([1.341, 0.1034, 0.6076, 1.4278, 0.0374], [0.37, 0.12, 0.22, 0.4, 0.08]) The x-axes appear log scaled but the points do not appear -- only two points appear. Any idea how to fix this? Also, how can I make this log scale appear on a square axes, so that the correlation between the two variables can be interpreted from the scatter plot? thanks.

• NHybernate, the Parallel Framework, and SQL Server

  - by andy

  hey guys, we have a loop that: 1.Loops over several thousand xml files. Altogether we're parsing millions of "user" nodes. 2.In each iteration we parse a "user" xml, do custom deserialization 3.finally, in each iteration, we send our object to nhibernate for saving. We use: .SaveOrUpdateAndFlush(user); This is a lengthy process, and we thought it would be a perfect candidate for testing out the .NET 4.0 Parallel libraries. So we wrapped the loop in a: Parallel.ForEach(); After doing this, we start getting "random" Timeout Exceptions from SQL Server, and finally, after leaving it running all night, OutOfMemory unhandled exceptions. I haven't done deep debugging on this yet, but what do you guys think. Is this simply a limitation of SQL Server, or could it be our NHibernate setup, or what? cheers andy

• Some problem running NUnit

  - by prosseek

  I have NUnit installed at this directory. C:\Program Files\NUnit 2.5.5\bin\net-2.0 When I try to run my unit test (mut.dll) in some random directory. I get the following error. I have to copy the mut.dll under the NUnit directory in order to run it. ProcessModel: Default DomainUsage: Single Execution Runtime: net-2.0 Could not load file or assembly 'nunit.framework, Version=2.5.5.10112, Culture=n eutral, PublicKeyToken=96d09a1eb7f44a77' or one of its dependencies. The system cannot find the file specified. What's wrong? Is there anything that I have to configure to run NUNit under any directory?

• Javascript and webshop tracking/affiliate across websites, how to do?

  - by H4mm3rHead

  Hi, I have a small front end to a webshop. All customers that go through my website and buy an item from the webshop I get back 5% of the amount. I need to find a way af tracking the customers i forward from my webshop to the other webshop. And then get the webshop to reply to me when the purchase has been made. In my webshop i have made a small page: collect.aspx that requests and saves the values passed in the querystring, something like this pseudo code: string orderid = Request["orderid"]; string amount = Request["amount"]; ..save to database On the webshop i forward customers to i get to insert a javascript on the last page in the purchase flow. I have tried a lot of things but it seems that the only thing that works is to fool the browser into thinking im referring a javascript, like this: <script type="text/javascript" src="http://domain.com/mypage.aspx?orderid=4&amount=45/> I saw how other trackers did their bit, and this seems to be the general way of doing it. With this script however, i get all the orders, i only want to log those that belong tome, those who entered through my website. Here is my big problem, how to do this? I added a cookie when the user opens my page, and i want to check for this cookie again when the purchase page make the callback. It weems that i cant get the cookie from the browser when it makes the "" call. This is really buggin me now. Could anyone please tell me how this is generally done, this tracking. And what am i missing in regards to this cookie thing? All ideas on how to do this is very welcome.

• Using "Show values as" option in Excel 2007 pivot table when source is SSAS cube?

  - by Brad

  I have an Excel 2007 pivot table showing "Year" across the top and "Month" down the side. What I am trying to do is represent the values as "% Difference" from the same month of the previous year. (Ex. If Jan-07 is $100,000 and Jan-08 is $120,000, I would like Jan-08 to show '20%'). However, every time I try to do this (using the "Show values as" tab of Value Field Settings) all of my numbers go to '#N/A'. Is there a way to do this using an Analysis Services cube as the data source? When I do this exact same thing using data on a different sheet as the data source for the pivot table, it works fine. Thanks in advance for any insight into this.

• Can django's auth_user.username be varchar(75)? How could that be done?

  - by perrierism

  Is there anything wrong with running alter table on auth_user to make username be varchar(75) so it can fit an email? What does that break if anything? If you were to change auth_user.username to be varchar(75) where would you need to modify django? Is it simply a matter of changing 30 to 75 in the source code?: username = models.CharField(_('username'), max_length=30, unique=True, help_text=_("Required. 30 characters or fewer. Letters, numbers and @/./+/-/_ characters")) Or is there other validation on this field that would have to be changed or any other repercussions to doing so? See comment discussion with bartek below regarding the reason for doing it.

• Ways to save enums in database

  - by corgrath

  Hey guys. I am wondering what the best ways to save enums into a database is. I know there are name() and valueOf() methods to make it into a String back. But are there any other (flexible) options to store these values? Is there a smart way to make them into unique numbers (ordinal() is not safe to use)? Any comments and suggestions would be helpful :) Update: Thanks for all awesome and fast answers! It was as I suspected. However a note to 'toolkit'; That is one way. The problem is that I would have to add the same methods with each enum type i create. Thats a lot of duplicated code and, at the moment, Java does not support any solutions to this (You cannot let enum extend other classes). However, thanks for all answers!

• PHP - Processing Invalid XML

  - by Paul

  I'm using SimpleXML to load in some xml files (which I didn't write/provide and can't really change the format of). Occasionally (eg one or two files out of every 50 or so) they don't escape any special characters (mostly &, but sometimes other random invalid things too). This creates and issue because SimpleXML with php just fails, and I don't really know of any good way to handle parsing invalid XML. My first idea was to preprocess the XML as a string and put ALL fields in as CDATA so it would work, but for some ungodly reason the XML I need to process puts all of its data in the attribute fields. Thus I can't use the CDATA idea. An example of the XML being: <Author v="By Someone & Someone" /> Whats the best way to process this to replace all the invalid characters from the XML before I load it in with SimpleXML?

• How often do you find javascript disabled on browsers?

  - by Mark Redman

  I have started using ajax/jQuery in our websites / application. There are many plugins that support degrading the javascript to browsers that dont have javascript enabled and techniques to support this. What are peoples thoughts on javascript support, we build applications rather than just websites and are looking to just support javascript enabled browsers as a pre-requisite assuming that most people or companies have javascript enabled. Do you find most people have javascript? do you monitor the percentage of javascript/non-javascript browsers (I guess this can be done with website stats) and what are the numbers regarding this?

• Setting a cell's format using Excel 2007 Interop and C#

  - by CVertex

  I'm using the office 2007 interop assemblies to create some excel spreadsheets. There are plenty of questions on here about getting started and MSDN contains heaps of articles, like this one. The API is funky, and sometimes a bit confusing. When I set a value of a cell, is there a way to set it's format? I'd like to mark particular fields as Date's so my customer can run excel macros on them. Also, numbers would be useful. Thanks!

• Searching for a semantic syntax highlighter in Javascript

  - by Boldewyn

  OK, I know, there are literally dozens of already available syntax highlighters out there. But I want one specifically, that implements line numbers through <ol/> lists. And that reduces the number of possible candidates to one, Lighter.js. Unfortunately, that is MooTools based, and since I decided some time ago to use jQuery, I don't want to embed yet another library just for syntax highlighting. The SyntaxHighlighter does something similar, but uses tables for the line numbering, and I don't want to hack it, if there is an already available tool, too.

• When *not* to use prepared statements?

  - by Ben Blank

  I'm re-engineering a PHP-driven web site which uses a minimal database. The original version used "pseudo-prepared-statements" (PHP functions which did quoting and parameter replacement) to prevent injection attacks and to separate database logic from page logic. It seemed natural to replace these ad-hoc functions with an object which uses PDO and real prepared statements, but after doing my reading on them, I'm not so sure. PDO still seems like a great idea, but one of the primary selling points of prepared statements is being able to reuse them… which I never will. Here's my setup: The statements are all trivially simple. Most are in the form SELECT foo,bar FROM baz WHERE quux = ? ORDER BY bar LIMIT 1. The most complex statement in the lot is simply three such selects joined together with UNION ALLs. Each page hit executes at most one statement and executes it only once. I'm in a hosted environment and therefore leery of slamming their servers by doing any "stress tests" personally. Given that using prepared statements will, at minimum, double the number of database round-trips I'm making, am I better off avoiding them? Can I use PDO::MYSQL_ATTR_DIRECT_QUERY to avoid the overhead of multiple database trips while retaining the benefit of parametrization and injection defense? Or do the binary calls used by the prepared statement API perform well enough compared to executing non-prepared queries that I shouldn't worry about it? EDIT: Thanks for all the good advice, folks. This is one where I wish I could mark more than one answer as "accepted" — lots of different perspectives. Ultimately, though, I have to give rick his due… without his answer I would have blissfully gone off and done the completely Wrong Thing even after following everyone's advice. :-) Emulated prepared statements it is!

• Finding the second highest number in array

  - by Richard Jackson

  I'm having difficulty to understand the logic behind the method to find the second highest number in array. The method used is to find the highest in the array but less than the previous highest (which has already been found). The thing that I still can't figure it out is why || highest_score == second_highest is necessary. For example I input three numbers: 98, 56, 3. Without it, both highest and second highest would be 98. Please explain. int second highest = score[0]; if (score[i] > second_highest && score[i] < highest_score || highest_score == second_highest) second_highest = score[i];

• Input array is longer than the number of columns in this table

DataTable table = new DataTable(); //exception is thrown here table = Global.db.ExecuteQuery("SELECT * FROM vm_manager"); Some of the data that gets returned from this query is as follows: http://i.imgur.com/9rlLN.png If anyone has any advice, I'd be grateful.

• XML/XHTML replace content?

  - by Daveo

  I have a XHTML string I want to replace tags in for example <span tag="x">FOO</span> <span tag="y"> <b>bar</b> some random text <span>another span</span> </span> I want to be able to find tag="x" and replace FOO with my own content and find tag=y and replace all the inner content with by own content. What is the best way to do this? I am thinking regex is definitely out of the question. Can XPATH do this or is that just for searching can it do manipulation?

• Load client-side accordion with pane open

  - by superexsl

  hey , I'm trying to change an AJAX accordion layout on the client-side. How can I make it so that when the page loads, the selected pane is opened? At the moment, I have this: Sys.require(Sys.components.accordion, function() { $("#accordion").accordion({ HeaderCssClass: "acc_header", HeaderSelectedCssClass: "acc_selectedheader", FadeTransitions: true, requireOpenedPane: false }); }); This works. However, if I add SelectedIndex = 1, it still starts off with the top pane opened and everything else closed. I tried change the 1 to other numbers (including -1), but it doesn't make a difference. Have I missed something here? (It's placed in an updatepanel, if that makes a difference) Thanks

• Printing elements out of list

  - by chavanak

  Hi, I have a certain check to be done and if the check satisfies, I want the result to be printed. Below is the code: import string import codecs import sys y=sys.argv[1] list_1=[] f=1.0 x=0.05 write_in = open ("new_file.txt", "w") write_in_1 = open ("new_file_1.txt", "w") ligand_file=open( y, "r" ) #Open the receptor.txt file ligand_lines=ligand_file.readlines() # Read all the lines into the array ligand_lines=map( string.strip, ligand_lines ) #Remove the newline character from all the pdb file names ligand_file.close() ligand_file=open( "unique_count_c_from_ac.txt", "r" ) #Open the receptor.txt file ligand_lines_1=ligand_file.readlines() # Read all the lines into the array ligand_lines_1=map( string.strip, ligand_lines_1 ) #Remove the newline character from all the pdb file names ligand_file.close() s=[] for i in ligand_lines: for j in ligand_lines_1: j = j.split() if i == j[1]: print j The above code works great but when I print j, it prints like ['351', '342'] but I am expecting to get 351 342 (with one space in between). Since it is more of a python question, I have not included the input files (basically they are just numbers). Can anyone help me? Cheers, Chavanak
