A collection of lessons learned from using Eclipse on Ubuntu

July 9, 2008 No comments

I have been running into a few woes on the home computing front that may or may not give rise to a number of posts on here. Having my Windows VM’s going awry on VMware is a more worrying development with my need to use a Windows-based application for my hillwalking mapping  but I am going to devote this entry to a spot of bother that I started to have with Eclipse, if only because I managed to sort that one out.

Up to yesterday, I had all my offline website development stuff in a single project area for sake of ease of testing. I suppose that I got led into this by my use of Dreamweaver and the way that it sets up what it calls Sites. Applying that same of working to Quanta Plus and Netbeans just chokes up the respective IDE’s and makes them less usable. Until recently, Eclipse escaped this because it seemed to check if a file had changed when you tried editing it and asked you if you wanted the latest version. This stopped in the last few days for whatever reason and it started to stall just like the others.

Naturally, I wanted to set it back as before so a certain amount of investigation was in order. I ended up refreshing my installation in /usr/lib, a manual extraction of the Eclipse PDT archive but that didn’t resolve the issue. In fact, it created another one but we’ll talk about that later. Creating a smaller project made it all work again and I’ll be building up a number of these.

The new issue pertained to the creation and selection of the Eclipse workspace. There was no problem using what I wanted it to use but it wouldn’t remember the setting. There was more blundering about before I happened on the cause: access permissions. I copied the new Eclipse files in as the root user and that meant that Eclipse couldn’t update its setting when I was running it under my own account. Running the editor using sudo sorted out the workspace selection issue for now but a more permanent fixing such as giving myself write access to the configuration directory and what’s in there remains an outstanding task.

The mention of the Eclipse workspace brings me back to the way that it was working before the upheaval hit me. It does keep a copy of every file that you edit in there and maybe more besides. Thus, having a copy of every file in the project would have meant that it didn’t need to do the constant churning being performed by Quanta or Netbeans. That’s impression that I have but I’ll sticking with smaller project bundles from now on. Learning all this was useful.

A reasonable requirement of an IDE

May 20, 2008 No comments

I have been having a play with NetBeans IDE Early Access for PHP and, while it has a lot to offer, one impression remains uppermost in my mind: it is so slow. I might have a project with a lot of files in it but start-up takes an age because of project checking. Other functionality such as text searching is far from speedy either. The sluggishness probably arises from this release being very early in its life cycle and it reminds me of how slow older versions of the Java IDE were, even if this is slower. For PHP development, I’ll be giving NetBeans a while to mature before taking another look at it.

On a similar note, I recently dispatched Quanta Plus from my system for sluggish start-ups and will not return to it because other alternatives such as Bluefish and Eclipse PDT fit my needs much better. I like my editors to be slick and responsive and Quanta has been around long enough for any slowness to be knocked out of it. However, I get the feeling that the extras have added bloat while I expect any additional functionality that I never use not to get in my way. It is for the latter reason that I was always able to get on with Dreamweaver and even run it on Ubuntu using the WINE library. If I really wanted a stripped out yet functional editor, Gedit would do most of what I need – it colour codes syntax for a variety of languages for a start - but it’s always handy to have a file system explorer window incorporated and I value any syntax checking and auto-completion as well. So, it looks as if Eclipse and Bluefish could be serving my needs for a while to come alongside so use Dreamweaver for online editing of website files.

Exploring AJAX

June 7, 2007 No comments

When I first started it, my online photo gallery started out simply as a set of interlinked HTML pages. Over time, I discovered frames (yes, them!) and started to make use of JavaScript to make the slideshows slicker. In those days, I was working off free webspace provided by my ISP and client-side scripting was the only tool that I had for enhancing functionality. Having tired of the vagaries of client-side scripting – the browser wars were in full swing and incompatibilities reigned supreme, I went with paid hosting in order to get access to tools like Perl and PHP for server-side processing; their flexibility compared to JavaScript was a breath of fresh air to me and I am still a fan of the server-side approach.

The journey that I have just described is one that I now know was followed by a lot of website builders around the same time. Nevertheless, I have still held onto JavaScript for some things, particularly for updating the DOM as part of making the pages more responsive to user interaction. In the last few years, a hybrid approach has been gaining currency: AJAX. This offers the ability to modify parts of a page without needing to reload the whole thing and that has generated a considerable amount of interest among web application developers.

The world of AJAX is evidently a complex one though the underlying principle can be explained in simple terms. The essential idea is that you use JavaScript to call a server-side script, PHP is as good an example as any, that returns either text or XML that can be used to update part of a web page in situ without the need to reload it as per the traditional way of working. It has opened up so many possibilities from the interface design point of view that AJAX became a hot topic that still receives much attention today. One bugbear is efficiency because I have seem an AJAX application lock up a PC with a little help from IE6. There will always remain times where server-side processing is the best route and that needs to balanced against the client-side and vice versa.

Like its forbear DHTML, AJAX is really a development approach using a number of different technologies in combination. The DHTML elements such as (X)HTML, CSS, DOM and JavaScript are very much part of the AJAX world but server-side elements such as HTTP, PHP, MySQL and XML are also very much part of the fabric of the landscape. In fact, while AJAX can use plain text as the transfer format, XML is the one implied by the AJAX acronym and XSLT is used to transform XML in HTML. However, AJAX is not limited to the aforementioned technologies; for instance, I cannot see why Perl cannot play a role in place of PHP and ASP can be used for the same things.

Even in these standards-compliant days, browser support for AJAX remains diverse, to say the least, and it is akin to having MSIE in one corner and the rest in the other. Mind you, Microsoft did introduce the tools in the first place but they used ActiveX and Mozilla created a new object type rather than continue this method of operation. Given that ActiveX is a Windows-only technology, I can see why Mozilla did what they did and it is a sensible decision. In fact, IE7 appears to have picked up the Mozilla way of doing things.

Even with the apparent convergence, there will continue to be a need for the AJAX JavaScript libraries that are currently out there. Incidentally, Adobe has included one called Spry with Dreamweaver CS3. Nevertheless, I still like to find out how things work at the basic level and feel somewhat obstructed when I cannot do this. I remember perusing Wrox’s Professional AJAX and found the constant references to the associated function library rather grating; the writing style didn’t help either.

My taking a more granular approach has got me reading SAMS Teach Yourself AJAX in 10 Minutes as a means for getting my foot in the door. As with their Teach Yourself … in 24 Hours series, the title is a little misleading since there are 22 lessons of 10 minutes in duration (the 24 Hours moniker refers to there being 24 lessons, each of one hour in length). Anything composed of 10 minute lessons, even 22 of them, is never going to be comprehensive but, as a means for getting started, I have to say that the approach seems effective on the basis of this volume. It has certainly whet my appetite for giving AJAX a go and it’ll be interesting to see how things progress from here.

Adobe CS3 Launch

March 28, 2007 No comments

Last night, I sat through part of Adobe’s CS3 launch and must admit that I came away intrigued. Products from the Macromedia stable have been very much brought under the Adobe umbrella and progressed to boot. One of these that attracts my interest in Dreamweaver and Adobe is promoting its AJAX capabilities (using the Spry library), its browser compatibility checking facility and integration with Photoshop, among other things. Dreamweaver’s CSS support also gets taken forward. In addition, Dreamweaver can now integrate with Adobe Bridge and Adobe Device Central. The latter allows you to preview how your site might look on a plethora of WAP-enabled mobile phones while the latter, unless I have been missing something, seems to have become a media manager supporting all of CS3 and not just Photoshop.

Speaking of Photoshop, this now gets such new features as smart filters, I think of these as adjustment layers for things like sharpening, monochrome conversion and much more. Raw image processing now has a non-destructive element and Photoshop Lightroom is being touted as a companion for the main Photoshop. Speaking of new additions to the Photoshop family, there is a new Extended edition for those working with digital imaging with a 3D aspect and this is targeted at scientists, engineers, medical professionals and others. It seems that data analysis and interpretation is becoming part of the Photoshop remit now as well.

Dreamweaver and Photoshop are the components of the suite in which I have most interest but I also note that Contribute now has blogging capabilities; it would be interesting to see how these work, especially given Word 2007’s support for blogging tools like WordPress and Blogger. Another member of note is Version Cue, adding version control to the mix and making CS3 more like a group of platforms than collections of applications.

Unsurprisingly, the changes are rung out for the rest of the suite with integration being a major theme and this very much encompasses Flash too. The sight of an image selection being copied straight into Dreamweaver was wondrous in its own way and rendering of Photoshop files into 3D images was also something to behold. The latter was used to demonstrate the optimisations that have been added for the Mac platform, a major selling point apparently.

I suppose that the outstanding question is this: do I buy into all of this? It’s a good question because the computer enthusiast seems to be getting something of a sidelining lately. And that seems to the impression left by Windows Vista in its giving the appearance that Microsoft is trying to be system administrator to the world. There is no doubt but CS3 is very grown up now and centred around work flows and processes. These have always been professional tools and the present level of sophistication and pricing* very much reflects this. That said, enthusiasts like me have been known to use them too, at least for learning purposes. The latter point may yet cause me to get my hands on Photoshop CS3 with its powerful tools for digital imaging but Dreamweaver is another story. It doesn’t fit what how I work now so this is an upgrade that I may give a miss, as impressive as it looks. For a learning experience, I might download a demo but that would a separate matter from updating my web presence. This time next month may tell a tale…

*Pricing remains the bugbear for the U.K. market that it always has been. At the present exchange rates, we should be getting a much better deal on Adobe products that we do. For instance, Amazon.com has the Web Premium CS3 suite from Macromedia Studio 8 priced at $493.99 while it is £513.99 on Amazon.co.uk. Using the exchange rate current as I write this, £1 buying $1.96605, the U.K. price is a whopping $1010.53 in U.S. terms. To me, this looks like price gouging and Microsoft has been slated for this too. I wonder what will be said to Adobe on this one.

A web development toolbox

March 23, 2007 No comments

Having been on a web building journey from Geocities to having a website with my own domain hosted by Fasthosts, I should come as no surprise that I have encountered a number of tools and technologies over this time and that my choices and knowledge have evolved too. I’ll muse over the technologies first before going on to the tools that I use.

Technologies

XHTML

When I started building websites, HTML 4 was not long in existence and I devoured most if not all of Elizabeth Castro’s Peachpit Visual Quickstart guide to the language in a weekend. Having previously used fairly primitive WYSIWYG tools like Netscape Composer and Claris Home Page, it was an empowering experience and the first edition (it’s now on its third) of Jennifer Niederst Robbins’ Web Design in a Nutshell took things much further, becoming something of a bible for a number of years.

When it first appeared, XHTML 1.0 wasn’t a major change from HTML 4 but its stricter more XML compliant syntax was meant to point the way to the future and semantic mark up was at its heart at least as much as it was for HTML 4. XHTML 2.0 is on the horizon and after the modular approach of XHTML 1.1 (which I have never used), it will be interesting to see how it develops. Nevertheless, there is a surprising development in that some people are musing over the idea of having an HTML 5. Let’s hope that the (X)HTML apple cart doesn’t get completely overturned after some years of relative stability. I still bear scars from the browser wars raging in the 1990’s and don’t want to see standards wars supplanting the relative peace that we have now. That said, I don’t mind peaceful progression.

CSS

Only seems to be coming into its own in the last few years and is truly an amazing technology in spite of the hobbles that MSIE places on our ambitions. CSS Zen Garden has been a major source of ideas; I wouldn’t have been able to customise this blog as much as I have without them. I was an early adopter of the technology and got burnt by inconsistent browser support; Netscape 4 was the proverbial bête noir back then, fulfilling the role that MSIE plays today. In those days, it was idea of controlling text display and element backgrounds from a single place that appealed. Since then, I have progressed to using CSS to replace table-based layouts and to control element positioning. It can do more…

JavaScript

Having had a JavaScript-powered photo gallery before my current Perl-driven one, I can say that I have definitely sampled this ever pervasive scripting language. Being a client side language rather than a server side one, it does place you rather at the mercy of the browser purveyors and it never ceases to amaze me that there is a buzz around AJAX because of this. In fact, the abundance of AJAX cross-browser function libraries is testimony to need for browser-specific code. Despite my preferences for server-side scripting, I still find a use for JavaScript and its main use for me these days is to dynamically control CSS elements to do such things as control the height of a page element or whether it is shown or not. Apparently, CSS may get some dynamic capabilities in the future and reduce my dependence on JavaScript. In the meantime, Jeremy Keith’s DOM Scripting (Friends of Ed) will prove as much of an asset as it has done.

XML

These days, a lot of the raw data underlying my personal website is stored in XML. I did try to dynamically transform the display of the XML into something meaningful with CSS and XSLT when I first scaled its dizzy heights but I soon resorted to other techniques. Browser support and the complexity of what I required were the major contributors to this. The new strategy involved two different approaches. The first was to create PHP/XHTML pages from the precursor XML off-line and this is how I generate the website’s directory pages. The other one is to process the XML as text to dynamically supply an XHTML page as the user visits it; this is the way that the photo gallery works.

Perl

This still powers all of my photo gallery. While thoughts of changing it all to PHP linger, there is a certain something about the Perl language that keeps it there. I suppose it is that PHP is entangled in the HTML while Perl encases the whole business and I am reasonably familiar with its syntax these days which is why it still does a lot of the data processing grunt work that I need.

PHP

PHP is everywhere these days, though it doesn’t attract quite the level of hype that used to be the case. It still appears with its sidekick MySQL in many website applications. Blogging software such as WordPress and content management systems like Drupal, Mambo and Joomla! wouldn’t exist without the pair. It appears on my website as the glue that holds my visitor directories together and is the processing engine of my WordPress blog. And if I ever get to a Drupal element to the site, by no means a foregone conclusion though I am spending a lot of time with it at the moment, PHP will continue its presence in my web site scripting as it powers that too.

Applications

Macromedia HomeSite

I have a liking for hand coding so this does most of what I need. When Macromedia (itself since taken over by Adobe, of course) took over Allaire, HomeSite sadly lost its WYSIWYG capability but the application still soldiers on even though Dreamweaver offers a lot to code cutters these days. Nevertheless, it does have certain advantages over Dreamweaver: it is a fleeter beast to start up and colour codes Perl syntax.

Macromedia Dreamweaver

There was a time when Dreamweaver was solely a tool for visual web page development but the advent of Dreamweaver UltraDev added server side development capabilities to the Dreamweaver family. These days, there is only one Dreamweaver version but UltraDev’s capabilities still live on in the latest version and I would not be surprised if they were taken further in these database-driven times.

Nowadays, Dreamweaver isn’t an application where I spend a great deal of time. In former times, when my site was made up of static HTML pages, I used Dreamweaver a lot even if its rendering capabilities were a step behind the then current browser versions. I suppose that it didn’t fit the way in which I worked but its template driven work flow would have been a boon back then.

However, my move from a static site to a dynamic one, starting with my photo gallery, has meant that I haven’t used it as much since then. However, with my use of PHP/MySQL components on my site. its server side abilities could get a the level of investigation that its PHP/MySQL capabilities allow.

Altova XMLSpy Professional

Adding MySQL databases to my web hosting costs money, not a lot but it could be spent on other (more important?) things. Hence, I use XML as the data store for my photo gallery and XML files are pre-processed into XHTML/PHP pages for my visitor directories prior to uploading onto the server.

I use XMLSpy to edit and manage the XML files that I use: its ability to view XML in grid format is killer feature as far as I am concerned and XML validation also proves very useful; particularly with regarding to ensuring that DTD’s and XML files are in step and for the correct coding of XSLT files. There are other features that I need to explore and that would also take my knowledge of the XML further to boot, not at all a bad thing.

Saxon

For processing XML into another file format such as XHTML, you need a parser and I use the free version of Saxon to do the needful, Saxonica offer commercial versions of it. There is, I believe, a parser in XMLSpy but I don’t use it because Saxon’s command line interface fits better into my work flow. This is a Perl-driven process where XML files are read in and XSLT files, one per XML file, built before both are fed to Saxon for transforming into XHTML/PHP files. It all works smoothly and updating the XML inputs is all that is required.

AceFTP

If I were looking for an FTP client now, it would be FileZilla but AceFTP has served me well over the last few years and it looks as if that will continue. It does have some extra features over FileZilla: transfers between remote sites, and scheduling, for example. I have yet to use either but they look valuable.

Hutmil

In bygone days when I had loads of static HTML files, making changes was a bit of a chore if they affected every single file. An example is changing the year on the copyright message on the page footers. Hutmil, which I found on a magazine cover-mounted disc, was a great time saver in those days. Today, I achieve this by putting this information into a single file and get Perl of PHP to import that when building the page. The same “define once, use anywhere” approach underlies CSS as well and scripting very usefully allows you to take that into the XHTML domain.

Apache

Apache is ubiquitous these days and both the online and offline versions of my site are powered by it. It does require some configuration but it is a very powerful piece of kit. The introduction of 2.2.x meant a big change in the way that configuration files were modularised and while most things were contained in a single file for 2.0.x, the setting are broken up into different files in 2.2.x and it can take a while to find things again. Without having it on my home PC, I would not be able to use Perl, PHP or MySQL. Apart from this, I especially like its virtual site capability; very useful for offline development.

WordPress

My hosting supplier offers blogs on Blogware but that didn’t offer the level of configuration that I would have liked. It is true that this is probably true of any host of blogs. I can’t speak for Blogger but WordPress.com does have its restrictions too. In order to make my hillwalking blog fit in with the appearance of my photo gallery, I went popped over to WordPress.org to download WordPress so that I could host a blog myself and have maximum control over its appearance. WordPress supports themes so I created my own and got my blog pages looking as if they are part of my website, rather than looking like something that was bolted on. Now that I think of it, what about WordPress supporting user created themes? I support that there is the worry of insecure PHP code but what about it?

MySQL

I am between minds on whether this is a technology or a tool. The SQL language certainly would be a technology but I am not so clear on what MySQL would be. In any case, I have classed it as a tool and a very useful one at that. It is the linchpin for my WordPress blogs and, if I go for a content management system like Drupal, its role would surely grow. While I do have a lot of experience with using SAS SQL and these helps me to deal with other varieties, there is still a learning curve with MySQL that gets me heading for a good book and Kofler’s The Definitive Guide to MySQL5 (Apress) seems to perform more than adequately in this endeavour.

Paint Shop Pro

As someone who hosts an online photo gallery, it won’t come as a surprise that I have had exposure to image editors. Despite various other flirtations, Paint Shop Pro has been my tool of choice over the years but it is now set to be usurped by a member of Adobe’s Photoshop family. Paint Shop Pro does have books devoted to it but it seems that Photoshop gets better coverage and I feel that my image processing needs to be taken up a gear, hence the potential move to Photoshop
