• Google Analytics - async tracking with two accounts

  - by MatW

  I'm currently testing GAs new async code snippet using two different tracking codes on the same page; _gaq.push( ['_setAccount', 'UA-XXXXXXXX-1'], ['_trackPageview'], ['b._setAccount', 'UA-XXXXXXXX-2'], ['b._trackPageview'] ); Although both codes work, I've noticed that they present inconsistent results. Now, we aren't talking huge differences here, only 1 or 2 visits / day every now and then. However, this site is tiny and 1 or 2 visits equates to a 15% difference in figures. Now, the final site has much more traffic, but my concerns are; will this inconsistancy scale with traffic? assuming not, is a slight variation in recorded stats an accepted norm?

• Best practice. Do I save html tags in DB or store the html entity value?

  - by Matt

  Hi Guys, I was wondering about which way i should do the following. I am using the tiny MCE wysiwyg editor which formats the users data with the right html tags. Now, i need to save this data entered into the editor into a database table. Should I encode the html tags to their corresponding entities when inserting into the DB, then when i get the data back from the table, not have the encode it for XSS purposes but I'd still have to use eval for the html tags to format the text. OR Do i save the html tags into the database, then when i get the data back from the database encode the html tags to their entities, but then as the tags will appear to the user, I'd have to use the eval function to actually format the data as it was entered. My thoughts are with the first option, I just wondered on what you guys thought.

• Views jump during ViewDidLoad

  - by Jon-Paul

  Hi, I have a custom button, subclassed from UIButton that is initialised as below (obviously all the button does is use a custom font). @implementation HWButton - (id)initWithCoder:(NSCoder *)decoder { if (self = [super initWithCoder: decoder]) { [self.titleLabel setFont:[UIFont fontWithName: @"eraserdust" size: self.titleLabel.font.pointSize]]; } return self; } So far so good. But when I use the custom class in my nib and launch the app, the button initially displays for a split second as tiny with small text, then grows. So the outcome is what I want, but I don't want to see the transition. Can anyone put me right? Thanks. JP

• Day dreaming about automatic RGB color function in PHP

  - by Sam

  Hello fellow earthlings. A quesion about RGB color and its usefulness in a simple tiny php code: Imagine I have variable $colorA containning a valid six char color. say B1B100, a greenish natural color. Now If I would like to make a new color from that, which is, say, ten steps lighter thatn that original color, roughly. $colorA = B1B100 // original color php code with little color engine lightening stuff up goes here $colorB = ?????? // original color lightened up Is there a php ready function that KNOWS rgb colors something like php function RGB ( input color, what to do, output color) Where what to do could be +/- 255 values of brightness etc etc. Is something like this already possible or am I day dreaming? rgb($colorA, +10, $colorB) If this does not exist, what would be the shortest code for doing this? Link suffices. Suggestions and ideas are answers to me. Thanks.

• PHP Thumbnail image generator works, but consistently awaits 90% of its loadtime! Why?

  - by Sam

  Hi folks, This is the follow-up question from this general page load speed question. This question which will focus only, entirely and specifically on the thumbnail generator PHP code with the question: What's causing the 97% delays on these tiny thumbnails? Measuring only 3 ~ 5 kb each, this is strange indeed! Even after 7 orso bounty-rounds and 100 upvotes, the images are still doing nothing for over 97% of the time. It works allright, but it could be so much faster! ZAM, my pet robot, was so annoyed by not knowing why, he just pulled out some cords! Silly metal box... (I have asked permission from the original author, to put temporarily segments of the code online that I think could be the problem, after which I will remove all code, except the several lines that were the direct cause of this issue here to match the answer. This will be the free opportunity to perfect/speedup his otherwise already to my opinion vert versatile and userfriendly thumbnail generator.)

• Correct way to (re)launch a Java application with hardware-dependent VM parameters?

  - by LowLevelAbstraction

  EDIT I don't want to use Java Web Start I've got a Java application that I'd like to run with different VM parameters depending on the amount of memory the system it is launched on has. For example if the machine has 1 GB of memory or less I'd like to pass "-Xmx200m" and "-Xmx400m" if it has 2 GB and "-Xmx800m" if it has 8 GB (these are just examples). Is there a portable way to do this? I've tried having a first tiny Java app (hence portable) that determines the amount of memory available and then launches a new Java app but I don't think this is very clean. As of now I've written Bash shell scripts that invoke the Java app with the correct parameters depending on the config but it only works on Linux on OS X. What is the correct way to solve this? Would application packager package ;) help ?

• matlab noninteger step indexing

  - by rlbond

  So, I have a vector: k = 1:100; And I want to take 19 elements from it, which are roughly equally-spaced. So I write this: m = k(1:(99/18):end); This works great, except for a tiny problem: Warning: Integer operands are required for colon operator when used as index m = 1 7 12 18 23 29 34 40 45 51 56 62 67 73 78 84 89 95 100 Now, I understand why this comes up, but I'd like to get rid of that warning. Is there a "right" way to do this without a warning?

• Choosing MooTools over Google closure?

  - by Shekhar

  I am in a process to select javascript library for our new web application. This app is not very UI heavy but has forms, reports, search, calendars, tabs and target multiple countries like most web apps. We are a tiny team. Biggest concern is maintainability and readability of the code. We are Python programmers. After evaluating many other javascript frameworks we have narrowed down to mootools and google-closure. We loved mootools syntax. It took us no time to learn. It's like Python. On other hand we were stumped seeing private/public in google closure. It's tempting to go for mootools however, I would love to hear from you about specific advantages these frameworks offer over each other.

• gethostbyname in C

  - by Matic

  I don't know how to write applications in C, but I need a tiny program that does: lh = gethostbyname("localhost"); output = lh->h_name; output variable is to be printed. The above code is used in PHP MongoDB database driver to get the hostname of the computer (hostname is part of an input to generate an unique ID). I'm skeptical that this will return the hostname, so I'd like some proof. Any code examples would be most helpful. Happy day, Matic

• OpenGL: small black pixel on top right corner of texture

  - by user308226

  I wrote an uncompressed TGA texture loader and it works nearly perfect, except for the fact that there's just one TINY little black patch on the upper right and it's driving me mad. I can get rid of it by using a texture border, but somehow I think that's not the practical solution. Has anyone encountered this kind of problem before and knows -generally- what's going wrong when something like this happens, or should I post the image-loading function code? Here's a picture, the little black dot is REALLY small. http://img651.imageshack.us/img651/2230/dasdwx.png

• Record locking problem between linux and Windows

  - by PabloG

  I need to run a bunch of old DOS FoxPro / Clipper applications in linux under DOSEMU. The programs access their "databases" located on a network server (could be a Windows or Linux server) Actually, the programs ran fine, but I cannot manage to make the record locking work as supposed: I can run a program in two terminals (or the server and any terminal for instance) and lock the same record in both. Now, I'm using Tiny Core Linux as terminal and Windows XP as server, accesing the shared files via CIFS and the latest DOSEMU (1.4.0), but I tried with various combinations of server (Ubuntu 7 to 9, Damn Small Linux, XP) <- protocol (CIFS, samba, various versions of smbclient) <- client (same as server) with no luck I tried to configure the server part to work without oplocks in samba (after reading the entire O'Reilly Samba book locking chapter in http://oreilly.com/catalog/samba/chapter/book/ch05_05.html ) and in XP (\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\LanmanServer\Parameters\UseOpportunisticLocking = 0) but the problem persist. Any ideas? TIA, Pablo

• Large number of Google Map Markers and IE6?

  - by Sivakanesh

  I'm working on an application that generates a large number of Google Map markers (2000 - 7000) via JSON. I'm also using MarkerCluster. It works quick on Chrome and FF but IE6 takes few minutes and just crashes the first time I try to zoom in. I'm not doing any more than just adding the markers to a map using JQuery & GMap API. So I looked at the following URL of the regular Google Map. http://maps.google.co.uk/maps?f=q&source=s_q&hl=en&q=hotel&sll=53.182996,-2.581787&sspn=1.494529,4.927368&ie=UTF8&split=1&rq=1&ev=p&hq=hotel&hnear=&ll=53.123702,-2.730103&spn=1.496594,4.927368&t=h&z=8 It shows a lot of tiny markers (~1000) and works fine on IE6. Do you have any ideas why this works and the markers added via the API struggles? Thanks

• How to visually represent file size

  - by Keith Williams

  This will be a bit subjective, I'm afraid, but I'd value the advice of the Collective. Our web application lists documents that users can download; standard file navigator stuff: Type Name Created Size ----------------------------------- PDF Doc 1 01/04/2010 15 KB PDF Doc 2 01/04/2010 15 MB Currently we list the file size as text, but I'd like to improve this by having some way of showing visually whether the file is tiny, normal or huge. The reason for this is so that users can scan the list quickly and spot files that are likely to take a long time downloading. My options currently are: Bigger font sizes for bigger files (drawback: the layout can become untidy) Icons (like a wi-fi signal strength indicator; drawback: harder to scan) Keep all sizes in KB so the number of zeroes indicates size (drawback: users have to calculate the "friendly" size in their heads) I know this is quite a minor thing, but I'd appreciate anyone's thoughts on the matter!

• Best way to remove CSS rounded-corner halo?

  - by Tauren

  I'm getting a tiny rounded corner halo effect that I'd like to get rid of. In this example, look for the effect in the red circle. I seem to recall a while back reading an article on just this problem. Anyone have a link to that article? Otherwise, any good ways to get rid of the halo? It is being caused because the dl has all four corners rounded. This allows the bottom of the dl to be rounded. The dt sits over the dl and has its top left and top right corners rounded. But there is a slight overflow of the dl curve behind the dt curve, causing the halo. My solution is to increase the border-radius of the dl so that it is hidden behind the dt corner. But it seems like a hack and adds a fair amount more CSS. I'm wondering if there is a better solution.

• For REST, how do I receive posted data using PHP?

  - by netrox

  I want to set up a tiny RESTful interface for my web services using PHP. The problem is that I looked at frameworks and I cannot figure out how do I recieve the posted data without field names? For example, if a server posts data to my server, I cannot figure out how do I get it without needing the postfield (POST variables). Traditionally, with forms, people send post data with field names such as this: curl_setopt($ch, CURLOPT_POSTFIELDS, postfield=postvalue); and I would use PHP code like this: $postvalue=$_POST[postfield]; to get value of postfield but since the server posting data is not using postfield and is just sending XML, how do I get it without fields? How do I capture the XML? That's where I am lost.

• When not to use a Drupal node?

  - by stotastic

  I've recently created a very simple CRUD table where the user stores some data. For the data, I created a custom node. The functionality works great for creating, editing, and deleting data in the CRUD table using the basic node functionality (I'm actually amazed how fast and easy it was to program the basic functionality with proper access controls using only a tiny bit of code).... Since the data isn't meant to be treated the same way as 'content' such as a blog post (no title, no body, no commments, no revisions, shouldn't show up on ?q=node page, no previews, no teasers, etc)... I find that I'm spending most of my time 'turning off' and modifying the stuff that drupal does automatically for nodes. I know its a matter of taste, but where should one draw the line on what should be treated as a node and what shouldn't? In other words, would it be better to program this stuff from scratch without using nodes?

• Optimizing an iphone app for 3G in landscape with opengl, camera, quartz

  - by Joey

  I have an iphone app that basically uses the camera, an opengl layer, and UIViews (some drawing with Quartz). It runs ok on 3GS, but on the 3G it is unusable. Particularly, when I press a UIButton, it literally takes sometimes 10 seconds to register the press. Shark doesn't do me much good because it crashes when I try to profile even a tiny portion, and I've tried turning off some of the layers to see if they might be obvious contributors to the lag. I've noticed that turning off the camera really helps. I'm wondering if anyone has any familiarity with this and might suggest some likely causes. I had issues with extreme slowdown from running my app in landscape mode and using transforms, so considered that might be a cause, but I'm wondering if hoping for a 3G to run something with all of the above elements is just not really possible considering the camera seems to really cost a lot. The fact that the buttons are horribly delayed in their response makes me think there is something fundamental that I might be missing.

• This PHP/Smarty doesn't work in IE

  - by Kyle Sevenoaks

  I'm starting to get sick of IE's random problems. Page link. (Add things to the cart with the kjøp button and handlevogn) I have this little tiny code here, {foreach $cart.taxes.$currency as $tax} <div id="subTotalCaption2"><p style="width:100px;">{$tax.name_lang}:</p></div> <div id="taxAmount2"><p>{$tax.formattedAmount}</p></div> {/foreach} That's meant to display the amount of total tax for each of the items in the basket. (MVA 25%) This works in every other browser but not IE. Why? Why not? Just why? Any help at all would be very much appreciated.

• How to Embed Image in Outlook Signature?

  - by BlackMael

  Is it possible to create an HTML email signature for Outlook 2003 or above that doesn't reference external images? That is, using those special "cid" reference but embed the image itself in the signature and not on the file system or network. This is for an web application that generates a "standard" email signature based on various input from a user. It has worked fine so far with a single "embedded" image. But a new feature is going to require the possible addition of multiple tiny images. Getting to user to save one email signature template and one image to the user's machine is about the limit of what I'd like to require of the user. But forcing the user to save multiple images seem to be pushing things a little to far in my opinion. So my problem is trying to embed the images into without having to inconvenience the user with multiple downloads first.

• Parallel CURL function Help .. php

  - by Webby

  Hello.. Firstly let me explain the code below is just a tiny snippet of the code I'm using on the working site. Basically I'm hoping someone can help me rewrite just the function below to enable parallel CURL calls... that way it will fit nicely into the existing code without me having to rewrite the whole from the ground up like some of the samples I've been finding today any ideas? function get_data($url) { $ch = curl_init(); $timeout = 5; curl_setopt($ch,CURLOPT_URL,$url); curl_setopt($ch,CURLOPT_RETURNTRANSFER,1); curl_setopt($ch,CURLOPT_CONNECTTIMEOUT,5); $data = curl_exec($ch); curl_close($ch); return $data; } p.s. $url goes through a huge bunch of urls in a loop already so I'd hole to keep that intact.. Help always appreciated and rewarded

• Removing the email validation requirement - Login Toboggan

  - by Rob Orr

  I'm building a premium membership site where a visitor can purchase a role and gain access to the privileged content using ubercart. I've got all that working fine, but the last tiny snag that my client wants to remove is to remove the validation email requirement that's fired when someone signs up on the site in Login Toboggan (6.1.9). I've got nothing set that is forcing this extra step and I've come to believe that this may be a feature in Drupal (acquia distro 6.22) core for any user that registers. I was hoping that this module (login toboggan) would eliminate that step but I've not as of yet been able to do so. I can allow the newly registered user access by setting that in the module, but the notification and validation email requirement still remains. Can anyone recommend a way around this? I just want them to be able to come to the site purchase their membership without any validation/confirmation email. Is this possible? Thanks - Rob
