Setting the timezone for Apache

Fortunately it is easy to tell Apache to use a different timezone, just add the following line to your .htaccess file.

SetEnv TZ Europe/London

This works nicely to set the timezone for the webserver and the programs that run within it, including PHP. This means that the PHP date and time functions will return the date/time as UK time rather than the server time.

Getting mySQL to use the right time

The only problem is that Apache doesn’t control mySQL, in fact on a shared hosting arrangement it isn’t possible to set mySQL’s timezone. I would be changing it for all the customers on my server which would suit me fine but may not make them happy.

This means that using a mySQL function like NOW() generates a Texas timestamp rather than a London timestamp which isn’t what I want. There are a number of solutions to this problem, Richard Lord has written a good, clear post about possible solutions on his blog.

What I want is something that uses the timezone from Apache but stores the date in a mySQL format so I can use mySQL date comparisons when I retrieve the data later on. Fortunately the answer is quite straightforward; Where I would use NOW() to generate a timestamp I use the PHP function:

date('Y-m-d H:i:s')

This uses the current date from Apache (which is set to the London timezone) but converts it to the mySQL DATETIME format so that you can use mySQL’s date processing functions on the data. Of course if you had calculated some other date in your PHP code you could use the same function but pass your calculated date to the function instead of letting it use the current date/time

date('Y-m-d H:i:s',$my_date)

So the SQL query you construct in PHP might look a bit like this:

$query = 'INSERT INTO filename (
          current_time_stamp,
          my_time_stamp)
          VALUES ("' . 
          date('Y-m-d H:i:s') . '", '" .          // replaces NOW()
          date('Y-m-d H:i:s',$my_date) . '")';    // replaces calculated date

That solved my particular date/time problem, I hope it helps you too.

Making dropdown menus work on the iPhone

After a bit of trial and error and a lot of searching on the internet I discovered that the problem was that the iPhone (and I believe the iPad too) doesn’t honour the :hover  pseudoclass.  I was able to find a solution here and modified my code accordingly.

All I had to do was add onmouseover=”"  to the li elements which contained ul elements for the dropdown menus. So;

<li onmouseover="">Top Level item
<ul>
<li>Dropdown item 1</li>
<li>Dropdown item 2</li>
</ul>
</li>

This solved the problem and made the iPhone display the drop down menu when the top level element was touched.  A simple solution to a subtle problem.

But why doesn’t the iPhone work like everything else?

It seems that the reason Apple have done this is because you can’t actually hover on a touchscreen, which sort of makes sense until you think of the consequences.  And if you can’t hover why do they honour the mouseover event which is surely the same thing?

One of the great things about smartphones is that they have good screens and good browsers so you can use the internet  reasonably well from a mobile device.  Unlike earlier attempts at mobile browsing, like WAP, any well designed website will work properly on a smartphone.  You can design websites to take advantage of the smartphone’s extra capabilities but the vast majority of existing websites are navigable without changes.  If only sites designed from scratch for mobile use could actually be navigated by a smartphone they wouldn’t have access to very much at all and would lose one of their main attractions.  Apple have broken this; There must be quite large sections of some sites which are invisible to iPhone users.

And I mean EVERYTHING else!

All our websites are tested very thoroughly in lots of  browsers.  It isn’t possible to test every possible combination but we test in; Internet Explorer versions 6 through 9, Chrome, Firefox, Opera and Apple’s Safari. This issue doesn’t appear in any of them, though of course we are not using a touch screen device with any these. Even on Electric Plum’s iPhone simulator the dropdown menus work fine.

We don’t have a Mac so we can’t use Apple’s IOS simulator, I would be very interested to know if this problem is replicated there. Significantly the problem does not seem to occur on Android phones, only Apple have taken this route. I think they have made the wrong choice.

But I need the facility to upload images to be integrated into the page being edited, CKfinder is a possibility, it integrates well with CKeditor, but it isn’t Open Source.  KCfinder is another possibility;  it  is Open Source but I found it difficult to do exactly what I wanted with it.  What I really wanted was to use class.upload.php which is Open Source and I know from experience does exactly what I want it to do.

The problem was that while I found some useful hints I couldn’t find clear instructions on the whole process of how to integrate class.upload.php with ckeditor.  So after some trial and error here is my solution.

Please note, class.upload.php is a file uploader, it doesn’t offer the file browser facilties that CKfinder and KCfinder provide. I have concentrated on the integration process rather than on the various parameters, both CKeditor and class.upload.php are quite well documented and once you have the upload process working it is just a matter of fine tuning until you get the result you want.

Getting CKeditor to call your custom upload script

I am calling CKeditor with javaScript from within a webpage so my calling code looks like this;

<!-- Set up CKeditor -->
<script src="ckeditor.js" type="text/javascript"></script>

<script type="text/javascript">
    function displayCkeditor(id)
    {
        if(CKEDITOR.instances[id])
        {
            CKEDITOR.remove(CKEDITOR.instances[id]);
        }

        CKEDITOR.replace(id,  {
            filebrowserUploadUrl :      "uploader.php?type=files,
            filebrowserImageUploadUrl : "uploader.php?type=images",
            filebrowserFlashUploadUrl : "uploader.php?type=flash"
        });

    }

</script>
<!-- CKeditor end -->

Creating the Custom Upload Script

And this is the script called by Ckeditor;

<?php
/**
 * uploader.php
 * Use class.upload.php to upload images etc.
 */
include(/includes/class.upload.php');          // where you have put class.upload.php

$msg = '';                                     // Will be returned empty if no problems
$callback = ($_GET['CKEditorFuncNum']);        // Tells CKeditor which function you are executing

$handle = new upload($_FILES['upload']);       // Create a new upload object 
if ($handle->uploaded) {
    $handle->image_resize         = true;
    //
    // Create a small image (thumbnail)
    //
    $handle->image_x              = 150;
    $handle->image_ratio_y        = true;

    $handle->process($_SERVER['DOCUMENT_ROOT'] . '/userfiles/');  // directory for the uploaded image
    $image_url = '/userfiles/' . $handle->file_dst_name;          // URL for the uploaded image
 
    if ($handle->processed) {
         $handle->clean();
    } else {
        $msg =  'error : ' . $handle->error;
    }
}

$output = '<script type="text/javascript">window.parent.CKEDITOR.tools.callFunction('.$callback.', "'.$image_url .'","'.$msg.'");</script>';
echo $output;
?>

The important part is the $output echoed back to CKeditor which tells it which function to link up with and the URL of the uploaded file (which will then be inserted into the text being edited). If the upload is successful the $msg field should be empty, otherwise it should contain an error message and the URL should be empty.

The code above is a working outline, obviously a bit more needs to be built in to make it a safe and useful bit of code but I have left it quite simple so that it is clear and useful for others to build on. I hope you find it useful.

Now you can use Event Tracking to track all sorts of things like ClickThrus, Downloads,  PDF reads, Media Plays and pretty much anything else you can think of.    I won’t go into how to implement Event Tracking as Google have a pretty good explanation in their Google Analytics Event Tracking Guide.  Event tracking works very well and lets you track an event in  several different ways by specifying category,  action, label and a value if you want to.

Missing pages in Webmaster Tools

Event tracking has been around for a little while now and I have used it on several newer sites but I never bothered to go back to older sites and replace the PageTracker technique with Event Tracking.  They still worked ok and still collected the information I wanted.  But one day I was checking out a site in Google Webmaster tools and I spotted that there were a lot of Crawl Errors, most of these errors were 404 errors relating to missing pages; dummy pages that I had specified in PageTracker!

Oops! It seems that Google being super clever had tried to follow my PageTracker code even though they didn’t point to real pages.  The links the PageTracker code was attached to still worked fine but Google was trying to find another page based solely on the PageTracker.

SEO Implications?

As far as I could tell this hadn’t hurt the SEO ranking of the site but I decided it was time to update it to use Event Tracking instead of PageTracker.  If Google thought there were a whole lot of 404s on the site that couldn’t be a good thing.  A few months on I haven’t notice any difference in SEO terms  or in traffic but at least I have tidied up all the Crawl Errors and avoided any potential future penalties, Google does like a tidy site.   And of course I can get more information from Event Tracking than I could from PageTracker.

I have been very happy with my Kindle.  I find the e-ink screen easy to read, no different really to reading a book.    The texture of the screen means that there is very little reflection, unlike reading on a mobile phone or tablet.  The size and shape of the Kindle and the positioning of the page forward and page back buttons make it very convenient to handle, much easier than a thick book.  I believe that earlier models were a bit sluggish but I find the page turn speed is fine on my Kindle, as quick as turning the page in a  real book.

Keyboard

My Kindle has no keyboard but there is a  little button which pops up a keyboard on the screen, you then use the 5-way controller button to  select the letters you want to type.  It works fine for searching, I haven’t experienced the Keyboard version of the Kindle but I don’t think there would be a lot of advantage in having the keyboard, at least for the Kindle’s primary purpose, reading books.

WiFi or 3G?

My Kindle is the cheaper WiFi only version, we have a fairly good broadband connection at home and we already have a Wifi network so we didn’t really see the need for 3G.  If you don’t already have WiFi network at home then 3G makes sense, you can still use WiFi if you are somewhere with a network but you can use Amazon’s Whispernet system to download books pretty much anywhere in the world (with no network charges).  If you travel a lot then 3G would be perfect and you can use the (experimental) browser to surf the web anywhere in the world too.

Case

I have a 3rd party leather case which adds to the size slightly but it gives it a bit more of a book like feel, otherwise I think it might just be a bit too slim and sleek.  The case also incorporates a stand so I can prop the Kindle up and read it while eating my breakfast if I want to.  Reading on the Kindle can be a totally hands free experience (except for page flips of course), whereas some books can be a bit of a hassle to read one handed.   My only complaint about the particular case I have is that the case slightly blocks the 5-way controller button on the Kindle making it a bit difficult to scroll down.

Reading Books and Manuals

I have two main uses for my Kindle, reading for pleasure and reading for work.  I find the Kindle perfect when reading normal books,  each page is a bit smaller than a regular book (though you can adjust the text size and font if you wish), but you don’t really care where the page breaks come when reading most books.  When reading a book for work, mostly computer books, you do notice that the page breaks on the Kindle don’t always match the page breaks in the original and things like program listings aren’t formatted quite as tidily as in a printed book.  Having said that, I haven’t found this to be a problem, everything is still quite readable and of course I can carry  several kilos of computer books on my 170g Kindle with no problem at all.

The Kindle uses black and white e-reader technology so obviously colour isn’t an option but pictures and diagrams are very clear, there is no apparent loss of definition.

Availability and Pricing of Books

The Kindle can handle various file formats including PDF (though not quite as nicely as mobi files) and ePub but the biggest source of  Kindle books is of course Amazon itself.  There are many thousands of books available for the Kindle but the market is still a bit patchy.  A lot of classic books (out of copyright) are free which is nice, I certainly plan to read a few classics that I have never got around to.  Newer books are often available in Kindle format but the price is not always competitive, sometimes it costs more for the Kindle book than the printed version which doesn’t make sense to me at all.  In between are a lot of older books which just aren’t available at all in any electronic format.

There is a bit of ironing out with licensing and marketing agreements between Amazon etc. and publishers before the ebook market becomes mature.

An Aside

I subscribe to The Economist (an excellent paper, and not really anything to do with economics at all, I can recommend it), I noticed that there was a Kindle edition which could be delivered electronically to my Kindle every Friday morning.  But the Kindle edition costs more than the printed edition which I receive in the post every Saturday!

I believe that the difference in cost is because the print edition is subsidized by  advertisements whereas the Kindle edition is ad free.   While I am quite happy to flip past the ads in the print edition I think they would be a lot more intrusive on the Kindle.  Nothing is simple is it?

E-reader or tablet?

Most Kindles (including mine) are e-readers rather than tablet computers, the exception being the new Kindle Fire (not yet available in the UK).  E-readers and tablet computers (like the Kindle Fire or the iPad) are superficially similar but actually fill quite different slots in the computer eco-system.

E-Readers

A proper E-reader will use e-ink (or similar) technology to display the text on the screen, there are colour e-ink screens in the pipeline but currently only monochrome screens are generally available.  E-ink screens are not backlit, they rely on an external light source,  if you want to read in the dark you will need a torch just as if you were reading a normal book.  Most e-readers have non-reflective screens which makes them very easy to read even in bright sunlight, there are some touch screen e-readers but so far no touch screen has the non-reflective characteristics which make e-readers so good.

The good thing about E-readers is the reading experience, it is very similar to reading a book and much less tiring than looking at a computer screen.  The non-reflective, non-backlit screen means you can use an e-reader pretty much anywhere in comfort.  They also have a very good battery life, you need to recharge every few weeks rather than every few hours.  They are a viable replacement for a whole stack of books (a very large stack of books).

The Kindle comes with a web browser (labelled as experimental) so you can use it to surf the web but it is pretty basic and of course the web you see will be monochrome rather than colour.    And of course using the pop up keyboard for any length of time would be tiresome.

Tablets

Tablet computers don’t have e-ink screens, they have lovely shiny touch screens which display wonderful colours and provide great interactions with the websites you visit and the apps you use.   They are backlit so you can read in complete darkness if you wish but they are shiny so even the best of them isn’t easy to read in bright sunlight.  They are also more tiring to read on than e-ink.

For a proper web browsing and app using experience a tablet is way ahead of an e-reader and of course you can get a Kindle app for your tablet  so you can read your books on it too.  The downsides are cost (even the Kindle Fire which is a pretty basic tablet costs about twice as much as a regular Kindle), readability (you are still reading a computer screen not a book) and battery life (hours rather than weeks).  Also the iPad (with its 10″ screen) is quite a bit bigger than the Kindle (with its 6″ screen)  so it isn’t quite as portable (or chuckable).

If you have an iPad then it makes sense to load the Kindle app so you read your books on the iPad but I wouldn’t want to use it as my main reading device (but then I don’t actually have an iPad).

Conclusion

I am very pleased with my Kindle, in fact I would like to use it even more but I still have a lot of old fashioned books.   I   plan to use it as my main way of reading  in the future, the only issue may be availability and pricing of books.

This new notice comes from an outfit called ZUNCH who only seem to have a gmail address zunchdomainservices@gmail.com which indicates that it is a pretty low budget attempt, you would think they would at least use their own domain name.  They do have a domain because Zunch.com advertises their Search Engine Optimization services.  Of course Zunch.com doesn’t necessarily have anything to do with zunchdomainservices@gmail.com but they do have the same street address and fax number.

This email isn’t a domain renewal scam, instead it is offering “Domain Name Search Engine Registration”, basically it seems to be an overpriced Search Engine Submission service.  They don’t say what they do for their fee, which ranges from $42 for 1 year up to a “Best Value” $499 lifetime service,  but they try to scare you into paying it by saying Failure to complete your Domain name search engine registration by the expiration date may result in cancellation of this offer making it difficult for your customers to locate you on the web. 

My advice is delete this email, it doesn’t offer anything worth paying for and may not offer anything at all.

Free Search Engine Submission

These days Google indexes new sites so quickly and so thoroughly that it often has a new site indexed before I set it up in Webmaster Tools (a free service),  Bing isn’t quite so quick but again Bing Webmaster Tools  is a free service which allows you to submit new sites and offers lots of good monitoring tools to go with it.  Yahoo has it’s site explorer (again free) and of course the Open Directory Project is free too.

Given that other search engines usually pick up their data from one of these sources 4 submissions usually gives pretty good results, covering well over 90% of searches. The only other search engine with a significant market share is Baidu but sadly my Chinese language skills are pretty limited.   If you have a site dealing with a particular niche there are specialist search engines which can be very useful but for most sites if you submit to Google, Bing, Yahoo and DMOZ your site will be found.

The Internet Explorer Nightmare

Microsoft is creating a nightmare for the web development world, IE6, 7 & 8 all have significant market shares still so need to be catered for. IE9 is much better of course but won’t run on anything older than Windows Vista which means that over half the world’s computers will never be able to run it, obviously this will change as people upgrade computers but at the time of writing IE6 still has nearly 10% of the browser market and Windows XP has over 50% of the OS market.

And now it seems that IE10 will only support Windows 7, not even Vista, this means that there will be another tranche of customers with Vista machines who are unable to upgrade beyond IE9.

It is very difficult to run more than one version of Internet Explorer on the same machine, I use VirtualBox to run several virtual Windows machines but that does mean that I need a separate Windows licence for each machine.

So my full browser array (on my main development machine)  is;

1. Opera – my default browser (I like Dragonfly)
2. Chrome – almost always open too
3. Firefox 6 – for all the great extensions
4. Safari -mostly for testing
5. IE6 – if it works here it usually isn’t too bad in later versions of IE
6. IE7 in an XP machine under VirtualBox
7. FF3.6 in the same XP machine under VirtualBox
8. IE8 in another XP machine under VirtualBox
9. IE9 in a Windows 7 machine under VirtualBox
10. IceMonkey under Knoppix under VirtualBox

Browser Deployment

You may notice that I didn’t refer to different versions of Chrome or Safari, that is because by default these browsers keep themselves up to date so the “tail” of older versions is very short.

Opera & Firefox do the same but the user has to actually agree to download major version changes, hence the tail of FF3.6 users, people have to agree to update to FF4 (but I think FF is now changing to the Chrome model for deployment). The same applies to Opera but as its user base is quite small and quite geeky (I use Opera as my default browser) it tends to look after itself.

Of course the major problem in the browser world is Internet Explorer. Usage of versions older than IE6 has fallen enough that I now ignore them when developing websites but all the later versions still need to be catered for (in my opinion – some developers take a much more aggressive view).  It is possible that IE7 usage will also shrink to almost nothing but I can’t see IE6 disappearing for quite a while yet and of course Windows XP still has a huge user base for whom IE8 is the best that can be installed.  And  there are a few million Vista users who can never go beyond IE9.

I’m sure Microsoft are aware of the mess they have created, I just wish they wouldn’t keep on doing it.  If Chrome/Opera/Firefox etc. can run on any version of Windows (and Mac and Linux) it doesn’t seem too much to ask that Internet Explorer should do the same.

Now I figure that a good proportion of people are using Firefox 3.6 or later, Chrome, Opera, Safari or Internet Explorer 9 (actually not too many of them yet but it is growing).  As long as what I did still looked ok in the older browsers I thought I would try out enhancements to make the site look a bit prettier.

So I styled the supplier images with rounded corners and drop shadows;

img.supplier {
float: left;
margin: 1em;
vertical-align:   top;
border: 4px solid #888;
border-radius: 5px;
-moz-border-radius: 5px;
box-shadow: 4px 4px 4px #888;
-moz-box-shadow: 4px 4px 4px #888;
/*   filter: progid:DXImageTransform.Microsoft.DropShadow(offx=4, offy=4, color=#888888);  */
}

Browser Support

The rounded corners are supplied by the border-radius directives and the drop shadows by the box-shadow directives.
I have also used the -moz versions of these directives to keep Firefox 3.6 happy (quite a few people haven’t yet moved to FF4), Firefox 4, Opera, Chrome and IE9 are happy with the standard directives. Safari uses the border-radius but doesn’t yet support box-shadow, it probably supports the -webkit version but I think it will catch up with Chrome pretty soon so I didn’t bother adding another line of code which would soon be redundant.

Now older browsers like IE6, IE7 & IE8 don’t support the CSS3 rounded corners or drop shadows but IE has supported drop shadows by a proprietary directive for a long time, so I added a filter directive to give the drop shadows.  All sorted!

But IE9 supports CSS3 AND filters

Oops! When I tested this in IE9 I discovered a problem, IE9 being a modern browser provides pretty good support for the CSS3 directives, but it is still Internet Explorer and also supports the filter directive.

The results weren’t very pretty, nice rounded corners and drop shadow with an ugly square drop shadow behind it.  This is why the last directive in the CSS above is commented out.

I needed a separate stylesheet to give the extra instructions to the older versions of Internet Explorer but not to IE9. So where I called the main stylesheet in my HTML page I added an extra bit of code.

<link href="stylesheet.css" rel="stylesheet" type="text/css" />
<!--[if lt IE 9]>
<link href="stylesIE.css" rel="stylesheet" type="text/css" />
<![endif]-->

/*
* This stylesheet contains only those styles which we need to make IE versions less than 9 work properly
* IE9 is close enough to a modern browser that it can use the main stylesheet
*/

img.supplier {
    filter: progid:DXImageTransform.Microsoft.DropShadow(offx=4, offy=4, color=#888888);  
}

The results?  After nearly 2 months of tracking I can say that about 2.5% have javaScript disabled, or 97.5% have javaScript enabled.

The website I have been tracking is  a business and visitor guide to Stow on the Wold.  I chose this site because it is fairly busy (about 4000 visitors per month) and because it very much a general purpose website with a wide cross-section of visitors.  I suspect that a more technical site might show more people with javaScript disabled, my theory is that most people don’t want to disable javaScript and wouldn’t know how to disable it if they did want to.

Update 21st December 2011 – A few more months of data show the percentage with javaScript disabled fairly steady at about 3%.   So about 97% of my visitors have javaScript enabled which is useful to know.
