An avalanche of innovation?

It seems that, almost in spite of the uncertain times or maybe because of them, it feels like an era of change on the technology front. Computing is the domain of many of the postings on this blog and a hell of a lot seems to be going mobile at the moment. For a good while, I managed to stay clear of the attractions of smartphones until a change of job convinced me that having a BlackBerry was a good idea. Though the small size of the thing really places limitations on the sort of web surfing experience that you can have with it, you can keep an eye on the weather, news, traffic, bus and train times so long as the website in question is built for mobile browsing. Otherwise, it’s more of a nuisance than a patchy phone network (in the U.K., T-Mobile could do better on this score as I have discovered for myself; thankfully, a merger with the Orange network is coming next month).

Speaking of mobile websites, it almost feels as if a free for all has recurred for web designers. Just when the desktop or laptop computing situation had more or less stabilised, along come a whole pile of mobile phone platforms to make things interesting again. Familiar names like Opera, Safari, Firefox and even Internet Explorer are to be found popping up on handheld devices these days along with less familiar ones like Web ‘n’ Walk or BOLT. The operating system choices vary too with iOS, Android, Symbian, Windows and others all competing for attention. It is the sort of flowering of innovation that makes one wonder if a time will come when things begin to consolidate but it doesn’t look like that at the moment.

The transformation of mobile phones into handheld computers isn’t the only big change in computing with the traditional formats of desktop and laptop PC’s being flexed in all sorts of ways. First, there’s the appearance of netbooks and I have succumbed to the idea of owning an Asus Eee. Though you realise that these are not full size laptops, it still didn’t hit me how small these were until I owned one.  They are undeniably portable and tablets look even more interesting in the aftermath of Apple’s iPad. You may call them over-sized mobile photos but the idea of making a touchscreen do the work for you has made the concept fly for many. Even so, I cannot say that I’m overly tempted though I have said that before about other things.

Another area of interest for me is photography and it is around this time of year that all sorts of innovations are revealed to the public. It’s a long way from what we thought was the digital photography revolution when digital imaging sensors started to take the place of camera film in otherwise conventional compact and SLR cameras, making the former far more versatile than they used to be. Now, we have SLD cameras from Olympus, Panasonic, Samsung and Sony that eschew the reflex mirror and prism arrangement of an SLR using digital sensor and electronic viewfinders while offering the possibility of lens interchangeability and better quality than might be expected from such small cameras. In recent months, Sony has offered SLR-style cameras with translucent mirror technology instead of the conventional mirror that is flipped out of the way when a photographic image is captured.  Change doesn’t end there with movie making capabilities being part of the toolset of many a newly launch  compact, SLD and SLR camera. The pixel race also seems to have ended though increases still happen as with the Pentax K-5 and Canon EOS 60D (both otherwise conventional offerings that have caught my eye though so much comes on the market at this time of year that waiting is better for the bank balance).

The mention of digital photography brings to mind the subject of digital image processing and Adobe Photoshop Elements 9 is just announced after Photoshop CS5 appeared earlier this year. It almost feels as if a new version of Photoshop or its consumer cousin are released every year, causing me to skip releases when I don’t see the point. Elements 6 and 8 were such versions for me and I’ll be in no hurry to upgrade to 9 yet either though the prospect of using content aware filling to eradicate unwanted objects from images is tempting. Nevertheless, that shouldn’t stop anyone trying to exclude them in the first place. In fact, I may need to reduce the overall number of images that I collect in favour of bringing away only good ones. The outstanding question on this is can I slow down and calm my eagerness to bring at least one good image away from an outing by capturing anything that seems promising at the time. Some experimentation but being a little more choosy can  save work later on.

While back on the subject of software, I’ll voyage in to the world of the web before bringing these meanderings to a close. It almost feels as if there is web-based application following web-based application these days when Twitter and Facebook nearly have become household names and cloud computing is a phrase that turns up all over the place.  In fact, the former seems to have encouraged a whole swathe of applications all of itself. Applications written using technologies well used on the web must stuff many a mobile phone app store too and that brings me full circle for it is these that put so much functionality on our handsets with Java seemingly powering those I use on my BlackBerry. Them there’s spat between Apple and Adobe regarding the former’s support for Flash.

To close this mental amble, there may be technologies that didn’t come to mind while I was pondering this piece but they doubtless enliven the technological landscape too. However, what I have described is enough to take me back more than ten years ago when desktop computing and the world of the web were a lot more nascent than is the case today. Then, the changes that were ongoing felt a little exciting now that I look back on them and it does feel as if the same sort of thing is recurring though with things like phones creating the interest in place of new developments in desktop computing such as a new version of Window (though 7 was anticipated after Vista). Web designers may complain about a lack of standardisation and they’re not wrong but this may be an ear of technological change that in time may be remembered with its own fondness too.

A CSS3 resource

While you could go over to the W3C and peruse its documentation, it’s always nice to see information being presented in a more user friendly way than dry specification documents. I know that CSS2.x adoption is still bumping along – IE comes to mind as a laggard – but CSS3 has some nice additions that I could use. One of these is border rounding, which is supported after a fashion by Firefox, Safari and Chrome (a very nice browser, even at this very early stage in its development; it’s Windows only for now so try out CrossOver Chromium if your OS preference is Linux or OS X). It would be very nice if CSS3 support was more advanced but that’s not how things are right now. Therefore, seeing a website like CSS3.Info with its latest CSS3 news and its previews, browser CSS selector testing among other things is a definite bonus.

A case of “peekaboo” behaviour in Internet Explorer

I recently changed the engine of my online photo gallery to a speedier PHP/MySQL based affair from its PHP/Perl/XML powered predecessor. On the server side, all was well but a peculiar display issue turned up in Internet Explorer (6, 7 & 8 were afflicted by this behaviour) where photo caption text on the thumbnail gallery pages was being displayed erratically. As far as I can gather, the trigger for the behaviour was that the thumbnail block was placed within a DIV floated using CSS that touched another DIV that cleared the floating behaviour. I use a table to hold the images and their associated captions in place. Furthermore, each caption was also a hyperlink nested within a set of P tags. The remedy was to set the CSS Display property for the affected XHTML tag to a value of "inline-block". With a cascade of DIV, TABLE, TR, TD, P and A tags, finding the right tag where the CSS property in question has the desired effect took some doing. As it happened, it was the tag set, that for the hyperlink, at the bottom of the stack that needed the fix. Of course, it’s all very fine fixing something for one browser but it’s worthless if it breaks the presentation in other browsers. In that vein, I did some testing in Opera, Firefox, Seamonkey and Safari to check if all was well and it was. There may be older browsers like versions of IE prior to 6 where things don’t appear as intended but I get the impression from my visitor statistics that the newer variants hold sway anyway. All in all, it was a useful lesson learnt and that’s never a bad thing.

O’Reilly does eBooks…

I have been a Safari subscriber for a while now and access to O’Reilly titles has been the main reason behind it. However, I recently discovered that O’Reilly is offering full eBooks of some of its titles. Why the offering is far from complete, this is progress and the prospect of donloading complete books with proper page numbering and an index is an appealing. Previously, I was downloading the individual chapters from Safari and compiling the books in that way, a less than user friendly approach. So, do I continue the Safari subscription or not?

A matter of fonts…

It’s when you pop from one operating system to another that you realise how operating system specific it is that fonts are. For instance, only one of the names in the following list are understood by Firefox on Ubuntu, the last one: Trebuchet MS, Lucida Grande, Verdana, Arial, Sans-Serif. The reason that San-Serif is understood is that it’s a general font class name in the world of CSS. However, that does not mean that you still are not at the mercy of operating system fonts. In fact, font sizes vary and 16px in one font isn’t the same as 16px in another; that can mean broken layouts if you are sufficiently clumsy.

As it happens, the main menu bar on my hillwalking blog should all fit on one line but it took up two lines when viewed on Linux. If it did that neatly, there wouldn’t be much of a problem but it didn’t. Some CSS hacking could have repaired the situation but I went for a simpler solution for now: picking a Linux sans serif font that fitted the bill better. So popping in mentions of "Nimbus Sans L" in appropriate places in my stylesheet was the way that I went. I don’t know how this appears in other Linux distributions but the wonders of virtualisation should allow to find out.

If I was really concerned about the fonts that were being used, I could have gone with a server-side approach: embedded fonts. I haven’t tried this for a while but differing browser support was a major issue when I did: you had to create a set of files for IE and for Netscape when I was investigating such things, hardly convenient even in those days when Opera was merely a speck on the horizon and Mozilla was nascent. It’s a valid approach for those exclusive fonts but so is questioning why you are using them in the first place. Adobe’s Flash is another option for those who obsess with fonts though how users take to this remains an open question, as does the accessibility of the approach.

I will be sticking with testing how things look in different operating systems and virtualisation is an excellent enabler of this, as are Live CD’s. The latter is particularly useful for Linux distributions which the former has application with more scenarios: names OpenSolaris and, with a spot of tinkering, OS X come to mind. It sounds like an intriguing proposition and Firefox is virtually a de facto cross-platform standard these days anyway. Mind you, seeing how websites are rendered by Safari running on OS X might be of interest to some.

Looking at from the user’s point of view rather than the web developer’s, there remains a question regarding the visiting of websites that break because of the font conundrum. If you find this happening to you a lot, it may be an idea to bring in some TrueType or OpenType fonts. With Ubuntu, this is straight forward: fire up Synaptic, search for msttcorefonts and install that package along with any of its dependencies. Logging off from and on to the system will make the new fonts available. There was a time when more work was needed than that…

Safari on Windows?

Steve Jobs recently surprised an audience at Apple’s Worldwide Developer’s Conference with the announcement that the Safari web browser is being made available for Windows. While everyone else is awaiting Apple’s forthcoming iPhone, the Safari announcement is a more important one to me; not being big on phones, I will let the iPhone excitement pass me by. Without either buying a Mac or running OS X in a virtual machine, there was no other way for me to test my web pages in Safari bar looking for a rendering site on the web. Now, that has all changed and I have downloaded the beta to have a look; it should iron out any rough edges that Mac users have been seeing.

Update: Safari seems to have got a mixed reaction from Windows users; some have tried it with Vista and cited issues. Another gripe has been its memory footprint but I have seen Firefox take up 100 MB.
