• IE 8 dialog windows not decompressing files

  - by Mike

  Hi, I've got a website where we have pre-compressed all of our HTML files. In general this works fine, but since IE 8 has come out some people are finding that they can not use some parts of the website. We've used the showModalDialog command to open a dialog window and pointing to one of our pre-compressed files but it displays it just show up as strange characters (ie not decompressed). Now it only happens in the dialog. I'm pretty sure our compression is all fine because the page they are viewing to open the dialog is also compressed. Has anyone else come across this or got any suggestions cuz i'm stumped??? Thanks, Mike

• Why does my jQuery animation require an extra click in IE8 to finish?

  - by Eric Reynolds

  I am pretty new to jQuery in general, however the following code works perfectly in Chrome and Firefox, but not in IE8. In IE8, I have to click anywhere on the page to start the animation after selecting a radio button. Here is the code: $("input[name=method]").change(function() { if($("input:radio[name=method]:checked").val() == 'installer') { $('#download').slideUp(0).removeClass("vendorSize").text("Download").addClass("installerSize").slideDown(500); } else if($("input:radio[name=method]:checked").val() == 'url') { $('#download').slideUp(0).removeClass("installerSize").text("Download From Vendor Website").addClass("vendorSize").slideDown(500); } }); Anyone know why this breaks in IE8 but not in the other browsers? If you feel this would work better using .animate (not that I think it should matter), can you provide an example of how to code it? Thanks, Eric R

• How can I hide the taxonomy field for authenticated users but show it for other users in Drupal 6?

  - by Jaymie

  I have a Drupal (v6.17) Content Type which includes a Taxonomy field. I want to hide this from ordinary Authenticated Users, but want it available to my Site Contributor role users, so they can review and then assign tags to user-created nodes. I've tried overriding the Node Add/Edit form in Panels 3 by creating a panel variant especially for Authenticated Users, which would exclude the Taxonomy field. However, the Taxonomy field is bundled in with the "General Form" controls - without showing this, I don't get the Title and Body fields. Is there a way I can either include the Title and Body fields without Taxonomy, OR hide just the Taxonomy field when the authenticated user role creates a node. I realise there's a CCK field which might be able to help me out here, but how do I tie that to the Taxonomy module? Any help gratefully received.

• Is it possible to temporarily disable Python's string interpolation?

  - by dangerouslyfacetious

  I have a python logger set up, using python's logging module. I want to store the string I'm using with the logging Formatter object in a configuration file using the ConfigParser module. The format string is stored in a dictionary of settings in a separate file that handles the reading and writing of the config file. The problem I have is that python still tries to format the file and falls over when it reads all the logging-module-specific formatting flags. { "log_level":logging.debug, "log_name":"C:\\Temp\\logfile.log", "format_string": "%(asctime)s %(levelname)s: %(module)s, line %(lineno)d - %(message)s" } My question is simple: how can I disable the formatting functionality here while keeping it elsewhere. My initial reaction was copious use of the backslash to escape the various percent symbols, but that of course permanently breaks the formatting such that it wont work even when I need it to. Also, general pointers on good settings-file practices would be nice. This is the first time I've done anything significant with ConfigParser (or logging for that matter). Thanks in advance, Dominic

• How to use Zend Cache with SimpleXML objects?

  - by Jeremy Hicks

  I'm trying to cache the user timeline of a Twitter feed using Zend_Service_Twitter which returns its results as a SimpleXML object. Unfortunately the regular serialize functions (which Zend Cache uses) don't play nice with SimpleXMl objects. I found this http://www.mail-archive.com/[email protected]/msg18133.html. So it looks like I'll need to create some kind of custom frontend for Zend Cache to be able to change the serialize function used. Anybody ever done this already or can point me where to look to start?

• Converting a JSP to a SharePoint webpart

  - by Kelly French

  We have a large number of Java based servlets/portlets running in a BEA portal that we want to convert into SharePoint 2007 webparts. Many of the portlets use user preferences but the implementations are split between preferences being handled by the portlet directly and stored in a separate database from the portal. Others are using the BEA WebLogic API for user preferences. Three questions: Has anyone gotten a Java Servlet/JSP (compiled against JRE 1.4.2 and running on Tomcat 4.1) to run as a SharePoint 2007 webpart? How large of an effort was it in general (as in, was it measured in days/weeks/months)? Would it be easier to rewrite the portlet as native webparts at least as far as user preferences are concerned?

• Optimising Database Calls

  - by Dwaine Bailey

  I have a database that is filled with information for films, which is (in turn) read in to the database from an XML file on a webserver. What happens is the following: Gather/Parse XML and store film info as objects Begin Statement For every film object we found: Check to see if record for film exists in database If no film record, write data for film Commit Statement Currently I just test for the existence of a film using (the very basic): SELECT film_title FROM film WHERE film_id = ? If that returns a row, then the film exists, if not then I need to add it... The only problem is, is that there are many many hundreds of records in the database (lots of films!) and because it has to check for the existence of a film in the database before it can write it, the whole process ends up taking quite a while (about 27 seconds for 210 films) Is there a more efficient method of doing this, or just any suggestions in general? Programming Language is Objective-C, database is in sqlite3 Thanks, Dwaine

• iPhone: Best Method for Passing Data to and from a Server

  - by SAPNA

  I am developing an iPhone application that downloads data from a website. The website database is implemented in SQL and the site itself uses the classic ASP interface. I am unsure as to which method would be best for transferring data to and from the server. Both JSON and SOAP require XML processing and I'm not sure how that affects performance or which of those two is best. What would be the best method in general for data transfer given the server configuration we currently have? I very new to this field and I'm a bit confused. Any help would be appreciated.

• Jquery DateJs, is there validation for full date?

  - by Cesar Lopez

  Hi all, I just find out about the power of date js, And its great!!! As I am a newbie I was wondering if there is any kind of general validitation for different types of full dates. eg. var d1 = Date.parse('2000-10-18, 10:06 AM'); alert(d1.toString('HH:mm')); If date is ('200-10-18, 10:06 AM'), of course it doesn't like it. So my question is if there is any quick way to validate the full date, rather than having to validate one by one. Thanks.

• MySQL Export with Column Heading

  - by st4nt0n

  Hello - I am very, very, new to mySQL. I've got experience in general technical terms, but not with the syntax or concepts of mySQL. I have been tasked with exporting a table from MySQL into a pipe delimited .txt or .xls that I can use to add 7500 more records to manually, then import back into the table. I tried to use INTO OUTFILE, but I don't get column headings, which I need for reference to merge the new records. Is there a good resource that can explain this to a complete novice? I would usually go down to my bookstore and start learning, but I'm on a bit of a time crunch. Thanks all!

• Do I correctly understand what a class is?

  - by Matt

  I've had trouble finding a clear, concise laymans definition of a class. Usually, they give general ideas without specifically spelling it out, and I'm wondering if I'm understanding this correctly. As I understand it, a class is the set of code that controls an object. For example, in an app that has a button for 'Yes' and a button for 'No', and a text box for output, the code that tells the computer what to do when the user uses the Yes button is one class, the code for hitting No is another class, and an object is the two buttons and what they do together to influence the output box. Am I right, or am I confusing terms here? Thanks

• How to setup testing LAMP environment to work with outsourcing companies?

  - by Kelvin

  Hello Guys, I need to setup testing LAMP environment in my office to work with outsourcing companies. This is what I think should be done on my side: Setup testing web server with the same configuration as on production Setup testing SQL server with "fake data"? Outsourcers should have access only to some part of original code Outsourcers should use CVS to update their code Once testing is finished someone releases the update ............ How would you separate original code and database from testing environment, but keep it as close as possible to production? What is the general practice for setting up testing environment and how other companies deal with outsourcers? I will appreciate for any of your thoughts and ideas from your personal experience. Maybe someone can suggest some article on this topic. Thank you a lot!

• Python: does it make sense to refactor this check into it's own method?

  - by Jeff Fry

  I'm still learning python. I just wrote this method to determine if a player has won a game of tic-tac-toe yet, given a board state like:'[['o','x','x'],['x','o','-'],['x','o','o']]' def hasWon(board): players = ['x', 'o'] for player in players: for row in board: if row.count(player) == 3: return player top, mid, low = board for i in range(3): if [ top[i],mid[i],low[i] ].count(player) == 3: return player if [top[0],mid[1],low[2]].count(player) == 3: return player if [top[2],mid[1],low[0]].count(player) == 3: return player return None It occurred to me that I check lists of 3 chars several times and could refactor the checking to its own method like so: def check(list, player): if list.count(player) == 3: return player ...but then realized that all that really does is change lines like: if [ top[i],mid[i],low[i] ].count(player) == 3: return player to: if check( [top[i],mid[i],low[i]], player ): return player ...which frankly doesn't seem like much of an improvement. Do you see a better way to refactor this? Or in general a more Pythonic option? I'd love to hear it!

• (type theoretical) How is ([] ==) [] typed in haskell?

  - by Ingo

  It sounds silly, but I can't get it. Why can the expression [] == [] be typed at all? More specifically, which type (in class Eq) is inferred to the type of list elements? In a ghci session, I see the following: Prelude> :t (==[]) (==[]) :: (Eq [a]) => [a] -> Bool But the constraint Eq [a] implies Eq a also, as is shown here: Prelude> (==[]) ([]::[IO ()]) <interactive>:1:1: No instance for (Eq (IO ())) arising from use of `==' at <interactive>:1:1-2 Probable fix: add an instance declaration for (Eq (IO ())) In the definition of `it': it = (== []) ([] :: [IO ()]) Thus, in []==[], the type checker must assume that the list element is some type a that is in class Eq. But which one? The type of [] is just [a], and this is certainly more general than Eq a = [a].

• How closely related is music composition to coding?

  - by ehsanul

  It seems to me as if there are a higher proportion of musicians in the programming field than in the general public. Maybe it's just an illusion caused by the fact that I'm an amateur guitarist myself, so I tend to notice coding musicians (or musical coders?) more. But I wonder if there really is some connection. Perhaps a shared set of skills or an innate quality that makes it more likely for someone who enjoys programming to also enjoy playing and composing music. How closely related is music composition to coding? I'd especially like to hear from the musicians around here.

• Cross-domain REST proxy with Javascript, HTML5

  - by Bosh

  I'm writing a service (say, service.com) that provides a REST API to external apps running inside of IFrames. (These apps are hosted from domains outside the service.com). I'm planning a javascript client library for the apps to make pure-javascript requests to the service.com REST API -- basically using postMessage and some ad-hoc encapsulation of my API calls to get messages back and forth across frames (from the outside-app.com IFrame -- service.com REST API, and back to the IFrame with a response). My question: is there any robust, general-purpose javascript library to accomplish the kind of cross-domain REST request proxying I need, or should I just hack it from scratch?

• deploying vb.net app with database on server

  - by vbNewbie

  I have an application that accesses a sql server 2008 database. The server and database is stored on my local harddrive and I would like to learn to scale this up to having multiple users in our office access the application which I will i deploy on a server. For now the database will stay on my pc until I am ready to put it on a dedicated server for myself but for now how do I allow the application still to access my database. Here is my current connection string: <add key="ConnectionString" value="Data Source=.;Initial Catalog=SearchEngine;User ID=sa;Password=pss;Trusted_Connection=False;" /> Now I know how to deploy a general vb.net application but what I dont know is what to do with the database.

• source control when starting up a new project

  - by jaras

  when starting with a project and using source control i find it hard to separate the things people are working on so they don't either write duplicate code or think it should be named one thing and so on. this problem diminishes over time because the general foundation is in place and it's easier to separate the tasks so they don't overlap as much how do you manage working with source control in the beginning phase? EDIT: I can see that it don't really have anything to do with source control, but it gets more apparent when you have source control too. so the question becomes more along the lines of "how do you manage to separate the tasks so they don't overlap too much. I think it's really hard and i haven't really seen much about how to do it.

• Google Vizualization with CSV data

  - by Shlomo Shmai

  Hi, I have a URL that returns data in CSV format. I would like to use Google Vizualization to create an interactive chart of the data. I've looked at several examples on Google Chart and Vizualization web page but I'm a bit confused as I'm not familiar with JavaScript or web programming in general. Question: Do I have to use JavaScript to parse the CSV string myself and manually construct the DataTable with addColumn() and addRows()? Or, is there a way to simply pass the CSV url to the charting function? I'm hoping to do something like this: var csv_data = get_data_from_url('http://...') var data = new google.visualization.DataTable(csv_data); var chart = new google.visualization.PieChart(document.getElementById('chart_div')); chart.draw(data, ...); Can someone please help me out? Thanks.

• In MS SQL Server, is there a way to "atomically" increment a column being used as a counter?

  - by Dan P

  Assuming a Read Committed Snapshot transaction isolation setting, is the following statement "atomic" in the sense that you won't ever "lose" a concurrent increment? update mytable set counter = counter + 1 I would assume that in the general case, where this update statement is part of a larger transaction, that it wouldn't be. For example, I think this scenario is possible: update the counter within transaction #1 do some other stuff in transaction #1 update the counter with transaction #2 commit transaction #2 commit transaction #1 In this situation, wouldn't the counter end up only being incremented by 1? Does it make a difference if that is the only statement in a transaction? How does a site like stackoverflow handle this for its question view counter? Or is the possibility of "losing" some increments just considered acceptable?

• Should I unit test my JavaScript?

  - by Joseph Silvashy

  I'm curious to if it would be valuable, I'd like to start using QUnit, but I really don't know where to get started. Actually I'm not going to lie, I'm new to testing in general, not just with JS. I'm hoping to get some tips to how I would start using unit testing with an app that already has a large amount of JavaScript (ok so about 500 lines, not huge, be enough to make me wonder if I have regression that goes unnoticed). How would you recommend getting started and Where would I write my tests? (for example its rails app, where is a logical place to have my JS tests, it would be cool if they could go in the /test directory but it's outside the public directory and thus not possible... err is it?)

• Searching Database by Arbitrary Date in PHP

  - by jverdi

  Suppose you have a messaging system built in PHP with a MySQL database backend, and you would like to support searching for messages using arbitrary date strings. The database includes a messages table, with a 'date_created' field represented as a datetime. Examples of the arbitrary date strings that would be accepted by the user should mirror those accepted by strtotime. For the following examples, searches performed on March 21, 2010: "January 26, 2009" would return all messages between 2009-01-26 00:00:00 and 2009-01-27 00:00:00 "March 8" would return all messages between 2010-03-08 00:00:00 and 2010-01-26 00:00:00 "Last week" would return all messages between 2010-03-14 00:00:00 and 2010-03-21 018:25:00 "2008" would return all messages between 2008-01-01 00:00:00 and 2008-12-31 00:00:00 I began working with date_parse, but the number of variables grew quickly. I wonder if I am re-inventing the wheel. Does anyone have a suggestion that would work either as a general solution or one that would capture most of the possible input strings?

• Help needed with MySQL query to join data spanning multiple tables with data used as column names

  - by gurun8

  I need a little help putting together a SQL query that will give me the following resultsets: and The data model looks like this: The tricky part for me is that the columns to the right of the "Product" in the resultset aren't really columns in the database but rather key/value pairs spanned across the data model. Table data is as follows: My apologies in advance for the image heavy question and the image quality. This just seemed like the easiest way to convey the information. It'll probably take someone less time to write the query statement to achieve the results than it did for me to assemble this question. By the way, the "product_option" table image is truncated but it illustrated the general idea of the data structure. The MySQL server version is 5.1.45.

• basic SQL atomicity "UPDATE ... SET .. WHERE ..."

  - by elgcom

  I have a rather basic and general question about atomicity of "UPDATE ... SET .. WHERE ..." statement. having a table (without extra constraint), +----------+ | id | name| +----------+ | 1 | a | +----+-----+ now, I would execute following 4 statements "at the same time" (concurrently). UPDATE table SET name='b1' WHERE name='a' UPDATE table SET name='b2' WHERE name='a' UPDATE table SET name='b3' WHERE name='a' UPDATE table SET name='b4' WHERE name='a' is there only one UPDATE statement would be executed with table update? or, is it possible that more than one UPDATE statements can really update the table? should I need extra transaction or lock to let only one UPDATE write values into table? thanks

• jQuery Resizable() UI Problem

  - by OneNerd

  In general, resizable() works fine. Here is where I am getting into an issue. I have a div that contains some resizable items that work fine (resizable() applied to them at some point). user can save items for later view (the innerHTML of the div gets saved into a JavaScript array, then div gets cleared so they can do something else) When items get placed back onto div (from array) -- I do a $('#divname').append(arrayname[i]); -- items are no longer resizable (although visually they have the resizable classes/handle on them) Here is what I have tried so far (none of which have worked): After append() line, I re-initialize the resizable -- $('#items').resizable(); After append() line, remove then re-add resizable -- $('#items').resizable('destroy').resizable(); Any help is appreciated - thanks.
