• Determining the hostname/IP address from the MX record in PHP

  - by pmmenneg

  Hi there, have a basic email domain validation script that takes a user's email domain, resolves the IP address from that and then checks that against various published blacklists. Here is how I am determining the IP: $domain = substr(strchr($email, '@'), 1); $ip = gethostbyname($domain); The problem is that some email address domains, such as [email protected], use an MX record rather than an A record, so using gethostbyname('alumni.example.net') will fail to resolve. I know when a user's email is using an MX in the email itself by using the PHP checkdnsrr function, but once at that stage am a little stuck as to how to proceed. In theory, I could parse out the 'root' domain, i.e. 'example.net' and check it, but I've not found reliable regex that can handle this task when the user could easily have an email the format of [email protected].uk... So, any suggestions on how to best tackle this??

• Writing JSON with XSLT

  - by JP

  Hi, I'm trying to write XSLT to transform a specific web page to JSON. The following code demonstrates how Ruby would do this conversion, but the XSLT doesn't generate valid JSON (there's one too many commas inside the array) - anyone know how to write XSLT to generate valid JSON? require 'rubygems' require 'nokogiri' require 'open-uri' doc = Nokogiri::HTML(open('http://bbc.co.uk/radio1/playlist')) xslt = Nokogiri::XSLT(DATA.read) puts out = xslt.transform(doc) # Now follows the XSLT __END__ <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns="http://www.w3.org/1999/xhtml"> <xsl:output method="text" encoding="UTF-8" media-type="text/plain"/> <xsl:template match="/"> [ <xsl:for-each select="//*[@id='playlist_a']//div[@class='artists_and_songs']//ul[@class='clearme']"> {'artist':'<xsl:value-of select="li[@class='artist']" />','track':'<xsl:value-of select="li[@class='song']" />'}, </xsl:for-each> ] </xsl:template> </xsl:stylesheet>

• Can i use a SELECT statement to define a CHECK constraint?

  - by Neel

  In MS SQL server, can i use a SELECT statement to define a CHECK constraint? Say i have to work with two tables "Customer Master" and "Indian Customer" in ideal situation both tables are compleatly different, and are not interrelated in anyways. however they share the same database Content of "Customer Master": CustomerName (colomn): a, b, c, d, e Branchlocation (colomn): IN, AU, IN, IN, UK Content of "Indian Customer": customerID (colomn): 1, 2, 3 CustomerName (colomn): a, c, d customer details (colomn): details1, details, details . . . In Table "Indian Customer" i want to put a constraint so that the users entring data in this table should not be able to enter customers that dont exist in "Customer Master" or whose branch location is not IN. also the tables are in the same project but are not directly related.

• Add Flickr RSS feed to Page via SimplePie

  - by Bradley Bell

  Hi all. I'm trying to add my recently uploaded flickr feed onto a site. I've followed tutorials with Simple Pie, but can't get what I desire. I need to be able dictate where each image will sit in multiple DIV's rather than just one repeated DIV. Here is a website which seems to do what I want.. wearecondiment.com It basically updates the Static URL inside each seperate DIV.. I cant find the PHP anywhere in there code. Here is the site I plan to add this feature to.. "http://www.openyourheart.org.uk" I'll make a new page and template of square DIVs where each photo will sit. The aim of it will basically be so that people can upload their own images to display in the campaign and automatically appear on the site. It would also be great if somehow the image could crop to the size of each square/rectangle. Any ideas? Cheers, Bradley

• How to create Shared VB Array Initialisors for NerdDinner

  - by David A Gibson

  Hello, I am trying to work my way through the NerdDinner tutorial - and as an exercise I'm converting it to VB as I go. I'm not very far in and after having gotten past the C# Yield statement I'm stuck on Shared VB Array Initialisors. static IDictionary<string, Regex> countryRegex = new Dictionary<string, Regex>() { { "USA", new Regex("^[2-9]\\d{2}-\\d{3}-\\d{4}$")}, { "UK", new Regex("(^1300\\d{6}$)|(^1800|1900|1902\\d{6}$)|(^0[2|3|7|8]{1}[0- 9]{8}$)|(^13\\d{4}$)|(^04\\d{2,3}\\d{6}$)")}, { "Netherlands", new Regex("(^\\+[0-9]{2}|^\\+[0- 9]{2}\\(0\\)|^\\(\\+[0-9]{2}\\)\\(0\\)|^00[0-9]{2}|^0)([0-9]{9}$|[0-9\\- \\s]{10}$)")}, Can anyone please help me write this in VB? Public Shared countryRegex As IDictionary(Of String, Regex) = New Dictionary(Of String, Regex)() {("USA", New Regex("^[2-9]\\d{2}-\\d{3}-\\d{4}$"))} This code has an error as it does not accept the String and the Regex as an item for the array.

• How can I switch timezones in Perl's 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.

• Trilateration using 3 latitude and longitude points, and 3 distances

  - by nohat

  There exists an unknown target location (latitude and longitude co-ordinates). I have 3 latitude and longitude co-ordinate pairs and for each pair a distance in kilometers to the target location. How can I calculate the co-ordinates of the target location? For example, say I have the following data points 37.418436,-121.963477 0.265710701754km 37.417243,-121.961889 0.234592423446km 37.418692,-121.960194 0.0548954278262km What I'd like is what would the guts of the function that takes that as input and returns 37.417959,-121.961954 as output look like? I understand how to calculate the distance between two points, from http://www.movable-type.co.uk/scripts/latlong.html I understand the general principle that with three circles you get exactly one point of overlap. What I'm hazy on is the math needed to calculate that point with this input.

• How do I do a postback to a CGI service

  - by TheLearner

  I am building a C# client for a CGI service (not sure what its called exactly). It accepts a bunch of XML and spits out a response. I have tested it straight in Firefox and it works (see below). Now I am not sure how to do this in C# code though?

• Creating a dataframe in pandas by multiplying two series together

  - by Aoife

  Say I have two series in pandas, series A and series B. How do I create a dataframe in which all of those values are multiplied together, i.e. with series A down the left hand side and series B along the top. Basically the same concept as this, where series A would be the yellow on the left and series B the yellow along the top, and all the values in between would be filled in by multiplication: http://www.google.co.uk/imgres?imgurl=http://www.vaughns-1-pagers.com/computer/multiplication-tables/times-table-12x12.gif&imgrefurl=http://www.vaughns-1-pagers.com/computer/multiplication-tables.htm&h=533&w=720&sz=58&tbnid=9B8R_kpUloA4NM:&tbnh=90&tbnw=122&zoom=1&usg=__meqZT9kIAMJ5b8BenRzF0l-CUqY=&docid=j9BT8tUCNtg--M&sa=X&ei=bkBpUpOWOI2p0AWYnIHwBQ&ved=0CE0Q9QEwBg Thanks!

• implementing SRX Segmentation Rules in JavaScript

  - by Sourabh

  Hello , I want to implement the SRX Segmentation Rules using javascript to extract sentences from text. In order to do this correctly I will have to follow the SRX rules. eg. http://www.lisa.org/fileadmin/standards/srx20.html#refTR29 now there are two types of regular expressions if found sentence should break like ". " if found sentence should not break like abbreviation U.K or Mr. For this again there are two parts before breaking after breaking for example if the rule is <rule break="no"> <beforebreak>\s*[0-9]+\.</beforebreak> <afterbreak>\s</afterbreak> </rule> Which says if the pattern "\s*[0-9]+.\s" is found the segment should not break. how do I implement using javascript, my be split function is not enough ?

• Evaluating php generated javascript "inline"?

  - by talkingnews

  If you look at the source of this page http://kingston.talking-newspapers.co.uk/ you will see a large amount of inline javascript near the top. I don't really want all this extra stuff floating around in my page source, I'd much rather get it off into a script tag, and then I can minify it and all sorts. If I call it as a php file, this SHOULD work in theory, I just end the js file extension with php instead, and in the header I put the following: header("Content-type:application/x-javascript"); but... a lot of the php variables used to generate the playlist within the javascript are setup at the beginning of the main index.php file, and in calling this php-generated js playlist file like this, it seems to evaluate it entirely separately, so it's full of errors. The only way round it I can think of is to have the page write a file, then immediately read it in. The other thing is, the playlist is likely to change often and dynamically, so I think I need to get minify to NOT cache it?

• Postcode and radius lookup recommendations

  - by WestDiscGolf

  I look after a number of divisional websites for a uk based membership organisation and what we want to do is provide, as well as other address functions, is a closest member lookup to a web user from the websites themselves. A few use cases that I want to fill: Case 1: The user puts in their post code and wants to see all the members in a 5/10/15/20/30/40 mile radius from them Case 2: The member puts in an area (city, county, etc.) and gets a list of members in that area. Essentially what I'm looking for is a programmable API which I can code against to do: post code lookup and returns addresses (after picking house number for example). search post code + radius (5miles, 10miles etc) and get a set of applicable post codes to then join onto the membership records in the database Any recommendations? It can be a quarterly update install on the server, it can be a queryable web service. I'm open to suggestions. Thanks in advance

• navigateToUrl AS3 is not opening a web browser

  - by Ronnie

  I have a textField on my stage named 'adBuy', which when clicked I want to open up my browser with the defined in URL request. However when I click on the 'adBuy' textField on my SWF it opens Coda, the piece of software I'm using to write this small piece of code? I am puzzled. Here is my code: adBuy.defaultTextFormat = adFormat; adBuy.textColor = 0xFF65CB; adBuy.x = 640; adBuy.y = 455; adBuy.text = "Buy Now"; parent.addChild(adBuy); adBuy.addEventListener(MouseEvent.CLICK, buyAdvert); var request:URLRequest = new URLRequest("http://www.google.co.uk"); function buyAdvert(event:MouseEvent):void { navigateToURL(request, "_blank"); trace("link clicked"); } Is there an error in my code, or is this a common problem for which there is an answer?

• Remove HTTP headers from a raw response

  - by Ed

  Let's say we make a request to a URL and get back the raw response, like this: HTTP/1.1 200 OK Date: Wed, 28 Apr 2010 14:39:13 GMT Expires: -1 Cache-Control: private, max-age=0 Content-Type: text/html; charset=ISO-8859-1 Set-Cookie: PREF=ID=e2bca72563dfffcc:TM=1272465553:LM=1272465553:S=ZN2zv8oxlFPT1BJG; expires=Fri, 27-Apr-2012 14:39:13 GMT; path=/; domain=.google.co.uk Server: gws X-XSS-Protection: 1; mode=block Connection: close <!doctype html><html><head>...</head><body>...</body></html> What would be the best way to remove the HTTP headers from the response in C#? With regexes? Parsing it into some kind of HTTPResponse object and using only the body? EDIT: I'm using SOCKS to make the request, that's why I get the raw response.

• How to create a BBC style (facebox?) help popup

  - by Ian Batten

  Hi guys, I have tried to take apart the code, but can't seem to replicate it. On the BBC weather homepage, http://news.bbc.co.uk/weather/, you will see a little help quetionmark in a circle in the top right corner or some of the boxes. When you click on it, it brings up a nice help popup, that looks a little like facebox. The main thing I like about this, is the little arrow that points back to the help button to the right of the container. Facebox is just a standard square. If anyone knows how to replicate this, some help would be greatly appreciated. Regards, Ian

• Web based delivery pricing system - where to start?

  - by jsims281

  I've been asked to quote on how long it would take to deliver a system such as can be found here: http://cgi.tnt.co.uk/ratechecker/enter_details.asp The client basically wants to give quotes for shipping based on a number of variables such as weight, distance etc, and for it to be accessible through their website. I've thought of the Drupal/Ubercart/Shipping combination but this isn't really what it's designed for. A paid for, off-the-shelf system would also be great but I can't seem to find any that do this properly.. What would be a good system to start with here, or alternatively is there a system that already does this?

• use jquery autocomplete with carousel for preview and selection

  - by dave

  Hi, I've successfully used jquery autocomplete to display a list of matching images based on user input. The user experience isn't great though due to the number of potential matches - even with fairly prescriptive input. I've found this example at nokia http://www.nokia.co.uk/support/download-software/device-software-update (I know it's written in flash) which would provide the ideal interface for what I'm trying to achieve. Does anyone have any pointers for doing this using jquery autocomplete as a starting point? Or better still know of an existing javascript library that provides this functionality? I'm using the latest release of jquery if that matters. Thanks, Dave.
