A new repository for GNOME 3 Extensions

6th December 2011

Not before time, the GNOME project has set up a central website for GNOME Shell extensions. It seems to be in the hands of extension developers to make GNOME 3 more palatable to those who find it not to their taste in its default configuration. If you are using Firefox, installation is as easy as clicking the ON/OFF icon for a particular plugin on its web page and then selecting install on the dialog box that pops up. Of all the browsers that you can use on GNOME, it seems to be Firefox that is only one that has this ability for the moment. The website may have the alpha legend on there at the moment but it works well enough so far and I have had no hesitation in using it for those extensions that are of interest to me. This is an interesting development that deserves to stay, especially when it detects that a plugin is incompatible with your version of GNOME. Currently, I use GNOME 3.2 and it pops up a useful menu for deactivating extensions when the desktop fails to load. That’s a welcome development because I have had extensions crashing GNOME 3.0 on me and running the GNOME Tweak Tool on the fallback desktop often was the only alternative. GNOME 3 seems to be growing up nicely.

A little look at Windows 8

6th November 2011

It has been a little while but I have managed to set up a VirtualBox virtual machine in order to take a look at the Developer Preview of the next version of Windows, something that I and others continue to call Windows 8 though Microsoft has yet to confirm the name. When I tried the installation before, it failed on me but that may have been due to having an earlier release of VirtualBox on my machine at that time. 4.1.14 has a preset for Windows 8 and I also happened to notice that it can create virtual hard disks that can be used with competitors like VMWare, Parallels and Virtual PC too. It’s an interesting development but I am left wondering why you’d need to do that when VirtualBox runs on most platforms anyway.

To get back to Windows 8, the installation ran near enough without any intervention apart form stating the language you wanted to use, U.K. English in my case. Starting up the operating system gains you a lock screen that you need to get out of the way so you can log in. It can be dragged out of your way or you can double-click on it or use the carriage return key to get rid of it. Quite why someone thinks it’s a good extra is a little beyond me when a log in screen would suffice. Logging in gets you the new start menu or, as I prefer to think of it, screen. By default, there are a good few Metro apps installed though I decided to rid myself of most of them.

Regarding those apps, one irritation could be that there isn’t that obvious a way to switch away from them to something else. Thankfully, ALT+TAB does seem to work and it has the most instantaneous effect. Otherwise, using the Windows key or hovering over the bottom left corner of the screen to get the menu that brings up the start screen. From the PC user’s point of view, I could see this needing a little more thought because it took a little while for me to figure out what to do. Closing Metro apps isn’t an option either unless you resort to the Task Manager to do so. Microsoft appears to want to leave them open from the point at which you start them until the PC is shut down. It’s a design decision that leaves me unconvinced though, particularly when thoughts of rogue apps running riot on a system come to mind. Then, a stop button could be handy.

There is no start menu as we have come to know it anymore with the start screen replacing it. However, it is possible to limit what’s on there to the software that you use most often an rearrange panels as you’d like them to be. Apart from hosting shortcuts for starting applications, it also acts as a task switcher like the task bar in Windows 7 and there is one of those in Windows 8 too when you jump to the desktop; handily, there’s a panel for that too. Installing Firefox added a panel to the start screen so a little thought has gone into such a common situation and that’s just as well. Still, there’s more work to be done because, currently, there’s no way of changing the background colour of the start screen without resorting to a hex editor or third party tools. Still, you can pick your own picture for the lock screen so things are not all locked down on you.

A preview of IE 10 is included and, apart from the occasional artifact when displaying one of my websites, it seems to work well enough as does Windows Explorer. However, apart from these and a smattering of Metro apps, the Developer Preview does feel barer that previous versions of Windows. However, it does appear that applications like Notepad, PowerShell and the Command Prompt are on there but you need to search for these. That also means that you know about them too so I’d suggest a better way of browsing the applications that are available too. This is one of the weaknesses of Ubuntu’s Unity interface and you need to search in the Dash to find them. Just starting to type in the Metro start screen (and other screens too, it seems) in Windows does trigger the completion of a search box much like what happens in the GNOME Shell Activities screen on systems with GNOME 3. While it’s good to see good ideas being reused from elsewhere, Microsoft might do well to note that you still can browse lists of applications in GNOME 3 too.

Shutting down Windows 8 also seems to be more convoluted than is the case with Windows 7. Logging off and then powering off from the log in screen is one approach and that was my early impression from GNOME 3 too. With the latter, I later was to discover a status menu plugin that added in the option where it was accessible or that using ALT key when clicking the status menu when the plugin wouldn’t work would do what I needed. Without logging off from Windows 8, you can do a shut down using the sidebar that appears on selecting Settings from the menu that pops up on hovering near the bottom left corner of the start screen or the Start button of the task bar of the desktop. Then, look for the power icon and select what you need from the menu that clicking on this icon produces. Of course, you may find that the ALT+F4 key combination when issued while on a clean desktop is the cleanest of all.

All in all, the Developer Preview of the next release of Windows looks fairly usable. That is not to say that there aren’t things that need changing. Apart from this being an early sight of what may be coming to us Windows users, it isn’t unknown for Microsoft to roll back on a radical move to make it more palatable to the user community. After all, it has to watch how it treats the corporate market too. The strong possibility of there being alterations is one thought that needs to be shared with those who are inclined to be losing their tempers at the moment and I have comments with unpleasant language out there on the web (none of that here, please, by the way). As for me, I like to look ahead in order to be forewarned about what’s coming my way in the world of computing. What I have seen so far of the next Windows release is reassuring though there are roughnesses such as PC shutdown and Metro app switching but Microsoft cannot commit commercial suicide either so these have to be fixed. It seems that the world of Microsoft operating systems is in flux with the company’s keeping a firm eye on the world of mobile computing with tablets being a major concern. Others may disagree but I can see Windows 8 working well on conventional PC’s and that’s no bad thing.

Moving from Ubuntu 10.10 to Linux Mint 10

23rd April 2011

With a long Easter weekend available to me and with thoughts of forthcoming changes in the world of Ubuntu, I got to wondering about the merits of moving my main home PC to Linux Mint instead. Though there is a rolling variant based on Debian, I went for the more usual one based on Ubuntu that uses GNOME. For the record, Linux Mint isn’t just about the GNOME desktop but you also can have it with Xfce, LXDE and KDE desktops as well. While I have been known to use Lubuntu and like its LXDE implementation, I stuck with the option of which I have most experience.

Once I selected the right disk for the boot loader, the main installation of Mint went smoothly. By default, Ubuntu seems to take care of this but Mint leaves it to you. When you have your operating system files on sdc, installation on the default of sda isn’t going to produce a booting system. Instead, I ended up with GRUB errors and, while I suppose that I could have resolved these, the lazier option of repeating the install with the right boot loader location was the one that I chose. It produced the result that I wanted: a working and loading operating system.

However, there was not something not right about the way that the windows were displayed on the desktop with title bars and window management not working as they should. Creating a new account showed that it was the settings that were carried over from Ubuntu in my home area that were the cause. Again, I opted for a less strenuous option and moved things from the old account to the new one. One outcome of that decisions was that there was a lot of use of the chown command in order to get file and folder permissions set for the new account. In order to make this all happen, the new account needed to be made into an Administrator just like its predecessor; by default, more restrictive desktop accounts are created using the Users and Groups application from the Administration submenu. Once I was happy that the migration was complete, I backed up any remaining files from the old user folder and removed it from the system. Some of the old configuration files were to find a new life with Linux Mint.

In the middle of the above, I also got to customising my desktop to get the feel that is amenable. For example, I do like a panel at the top and another at the bottom. By default, Linux Mint only comes with the latter. The main menu was moved to the top because I have become used to having there and switchers for windows and desktops were added at the bottom. They were only a few from what has turned out not to be a short list of things that I fancied having: clock, bin, clearance of desktop, application launchers, clock, broken application killer, user switcher, off button for PC, run command and notification area. It all was gentle tinkering but still is the sort of thing that you wouldn’t want to have to do over and over again. Let’s hope that is the case for Linux Mint upgrades in the future. That the configuration files for all of these are stored in home area hopefully should make life easier, especially when an in-situ upgrade like that for Ubuntu isn’t recommended by the Mint team.

With the desktop arranged to my liking, the longer job of adding to the collection of software on there while pruning a few unwanted items too was next. Having had Apache, PHP and MySQL on the system before I popped in that Linux Format magazine cover disk for the installation, I wanted to restore them. To get the off-line websites back, I had made copies of the old Apache settings that simply were copied over the defaults in /etc/apache (in fact, I simply overwrote the apache directory in /etc but the effect was the same). MySQL Administrator had been used to take a backup of the old database too. In the interests of spring cleaning, I only migrated a few of the old databases from the old system to the new one. In fact, there was an element of such tidying in my mind when I decided to change Linux distribution in the first place; Ubuntu hadn’t been installed from afresh onto the system for a while anyway and some undesirable messages were appearing at update time though they were far from being critical errors.

The web server reinstatement was only part of the software configuration that I was doing and there was a lot of use of apt-get while this was in progress. A rather diverse selection was added: Emacs, NEdit, ClamAV, Shotwell (just make sure that your permissions are sorted first before getting this to use older settings because anything inaccessible just gets cleared out; F-Spot was never there is the first place in my case but it may differ for you), UFRaw, Chrome, Evolution (never have been a user of Mozilla Thunderbird, the default email client on Mint), Dropbox, FileZilla, MySQL Administrator, MySQL Query Browser, NetBeans, POEdit, Banshee (Rhythmbox is what comes with Mint but I replaced it with this), VirtualBox and GParted. This is quite a list and while I maybe should have engaged the services of dpkg to help automate things, I didn’t on this occasion though Mint seems to have a front end for it that does the same sort of thing. Given that the community favour clean installations, it’s little that something like this is on offer in the suite of tools in the standard installation. This is the type of rigmarole that one would not draw on themselves too often.

With desktop tinkering and software installations complete, it was time to do a little more configuration. In order to get my HP laser printer going, I ran hp-setup to download the (proprietary, RMS will not be happy…) driver for it because it otherwise wouldn’t work for me. Fortune was removed from the terminal sessions because I like them to be without such things. To accomplish this, I edited /etc/bash.bashrc and commented out the /usr/games/fortune line before using apt-get to clear the software from my system. Being able to migrate my old Firefox and Evolution profiles, albeit manually, has become another boon. Without doubt, there are more adjustments that I could be making but I am happy to do these as and when I get to them. So far, I have a more than usable system, even if I engaged in more customisation than many users would go doing.

It probably is useful to finish this by sharing my impressions of Linux Mint. What goes without saying is that some things are done differently and that is to be expected. Distribution upgrades are just one example but there are tools available to make clean installations that little bit easier. To my eyes, the desktop looks very clean and fond display is carried over from Ubuntu, not at all a bad thing. That may sound a small matter but it does appear to me that Fedora and openSUSE could learn a thing or too about how to display fonts on screen on their systems. It is the sort of thing that adds the spot of polish that leaves a much better impression. So far, it hasn’t been any hardship to find my way around and I can make the system fit my wants and needs. That it looks set to stay that way is another bonus. We have a lot of change coming in the Linux world with GNOME 3 on the way and Ubuntu’s decision to use Unity as their main desktop environment. While watching both of these developments mature, it looks as if I’ll be happily using Mint. Change can refresh but a bit of stability is good too.

Making a custom button to hide or display the Google Toolbar in Firefox

27th February 2011

Adding more toolbars to Firefox is all very fine but they can take up space on the screen. Even with the big screens that many of us have these days, it’s still nice to be able to see more of what we use web browsers to visit: web pages. For the Web Developer extension’s toolbar, there is the Toggle Web Developer Toolbar plugin for showing and hiding the thing when so desired. As it happens, I keep it hidden until I need it and I fancied doing exactly the same thing with the Google Toolbar but found none. Instead, I happened on a tutorial that used the Custom Buttons plugin to define a custom button. That gives you an entry named Add new button… to the context menu that appears when you right-click on the main menu bar near the top of the Firefox window. When you select the that extra entry in the menu, you get the dialogue box that you see below.

Making a custom button to hide or display the Google Toolbar in Firefox

In there, that are some form fields that need filling. Button URL is an option without which you can do but I entered “Toggle Google Toolbar” into the Name field while also sourcing an image to be used on the button instead of the default (a Google logo, naturally…). The last step is to add the code below underneath the /*CODE*/ comment line, leaving the latter in place.

const toolbar = document.getElementById(“gtbToolbar”);
toolbar.collapsed = !toolbar.collapsed;

With all that completed, clicking on the OK button is all that’s needed to finish off the button definition. With that done, the next step is to add the button where you want it by right clicking on the top menu bar again and selecting the Customise… entry. From the list of buttons that appears, just pick the new one and drag it to where you want it to go. Then, you’re done with what might sound a roundabout away of putting in place a space saver but I can live with that.

Looking at a few Operating Systems

19th February 2011

The last few weeks have seen me poking around with a few different operating systems to see how they perform. None of these were particularly in-depth in their nature but brushes with alternatives to what I currently use for much of the time. While I am too sure what exactly has kicked off all of this curiosity, all of the OS’s that I have examined have been of the UNIX/Linux variety. With the inclusion of Unity in the forthcoming Ubuntu “Natty Narwhal” 11.04, I am mindful of the need to be keeping an eye on alternative options should there ever be a need to jump ship. However, a recent brush with an alpha version has reassured me a little. Then there are interesting OS releases too and I recently forgot the Ubuntu password (a silly thing to do, I know) for my Toshiba laptop too so I suppose that a few things are coming together.

It was that latter development that got me looking in amazement at the impressive minimalism of CrunchBang Linux before settling on Lubuntu to see how it did; these were Live CD runs so I tried before I committed to installing. It helped that the latter was based on Ubuntu as its name suggests so I wasted little name in finding my way around the LXDE desktop. By default, everything supplied with the distro is lightweight with Chromium coming in place of Firefox. There’s no sign of OpenOffice.org either with offerings like Abiword coming in its stead. For the sake of familiarity, I started to add the weight of things without reducing the speed of things, it seems. Well, the speedy start-up wasn’t afflicted anyway. Being an Ubuntu clone meant that it didn’t long to add on Firefox using the apt-get command. LibreOffice was downloaded for installation using the dpkg command and it seems much more fleet-footed than its OpenOffice.org counterpart. As if these nefarious actions weren’t enough, I started to poke in the settings to up the number of virtual desktops too. All in all, it never stopped me going against what be termed the intent of the thing. In spite of what Linux User & Developer has had to say, I think the presentation of the LXDE desktop isn’t unpleasant either. In fact, I reckon that I quite like it and the next thing to do is to restore the entry for Windows 7 on the GRUB menu. Well, there’s always somthing that needs doing…

While I may have learned about it after the event, the release of Debian “Squeeze” 6.0 was of interest to me too. Well, I have used it a fair bit in the last few years and retain a soft spot for it. The new release comes on two kernels: GNU/Linux and FreeBSD. Regarding the latter, I did try having a look but it locked up my main home PC when I tried booting it up in a VirtualBox virtual machine. Given that it’s a technical preview anyway, I think it better to leave it mature for a while no matter how fascinating the prospect may be. Or is it VirtualBox 4.x that hasn’t around long enough? Debian’s latest Linux incarnations showed no such inclinations though I found that the CD ISO image that I’d downloaded didn’t give such a complete system when I fired it up after doing the installation. Being someone that knows his way around Linux anyway, it was no problem to add the missing pieces using apt-get though that’d stop it being an option for new users unless the DVD installation yields more complete results. Other than that, it worked well and I lost no time getting to grips with the OS and it’s gained a much fresher feel than version 5.x (“Lenny”). In summary, I look forward to continuing my investigations of the new Debian.

To round up my explorations of different UNIX/Linux operating systems, I have updated my test installations of Ubuntu 11.04. Initial looks at the next Ubuntu release weren’t so encouraging but things are coming along by all accounts. For one thing, Unity can be switched off in favour of the more familiar GNOME desktop that we’ve had for the last few years. The messages that popped up telling you that there’s no 3D graphics support on your machine have been replaced by graceful degradation to the GNOME and that’s no bad thing either. In case it hasn’t been so obvious, I am one of those who needs convincing by the likes of Unity and GNOME Shell so I’ll sit on the fence for a while. After all, there always are alternatives like LXDE if I want to decamp to something else entirely. One of the nice things about Linux is the amount of that we all have; it might be tricky to choose sometimes but it always is good to be able to find a niche somewhere else when someone makes a decision that doesn’t suit you.

A spot of extension bother with Firefox

8th December 2010

One keystroke that I use a lot when typing on a computer is Control+Shift+[an arrow key] but I found myself in the awkward position of it not working in Firefox anymore. The nuisance level was enough to set me investigating in the name of resolving the problem. Using the following command to start Firefox saw the keystroke being returned to me so I need to find which plug-in, extension or add-on was the cause of the matter.

firefox -safe-mode

Then, it was a matter of disabling one extension at a time and restarting Firefox each time to see when the keystroke functionality was returned to me. The culprit turned out to be Firebug 1.6 and there’s a discussion on their bug forum about the issue. Even the good folk in the Firebug project noted how many folk were experiencing the inconvenience based on a quick Google search. However, that didn’t turn up the answer for me so I had to do some digging of my own and I hope that it has saved you some time. Of course, Firebug comes without cost so we cannot grumble too much but I’ll be keeping it disabled as much as possible until a new version makes its appearance.

 

Update 2011-01-15: This now seems to be fixed in Firebug 1.6.1

A lot of work ahead

6th December 2010

Curiosity recently got the better of me and I decided to have a look at the first alpha release of Ubuntu 11.04, both in a VirtualBox virtual machine and on a spare PC that I have. They always warn you about alpha releases of software and the first sight of Ubuntu was in keeping with this. The move to using Unity as a desktop environment is in train and it didn’t work perfectly on either of the systems on which I tried it, not a huge surprise really. There wasn’t any sign of a top panel or one at the side and no application had its top bar, either. It looks as if others may have got on better but it may have been to my doing an in situ upgrade rather than a fresh installation. Doing the latter might be an idea but I may wait for the next alpha release first. Still, it looks as if we’ll be getting Firefox 4 so the change of desktop isn’t going to be the only alteration. All in all, it looks as if Natty Narwhal will be an interesting Ubuntu release with more change than is usually the case. In the meantime, I’ll keep tabs on how development goes so as to be informed before the time to think about upgrading comes around. So far, it’s early days and there a few months to go yet.

An avalanche of innovation?

23rd September 2010

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.

On web browsers for BlackBerry devices

8th August 2010

The browser with which my BlackBerry Curve 8520 came is called Web’n’Walk and, while it does have its limitations, it works well enough for much of what I want to do. Many of the sites that I want to visit while away from a PC have mobile versions that are sufficiently functionality for much of what I needed to do. Names like GMail, Google Reader, Met Office and National Rail come to mind here and the first two are regularly visited while on the move. They work well to provide what I need too. Nevertheless, one of the things that I have found with mobile web browsing is that I am less inclined to follow every link that might arouse my interest. Sluggish response times might have something to do with it but navigating the web on a small screen is more work too. Therefore, I have been taking a more functional approach to web usage on the move rather than the more expansive one that tends to happen on a desktop PC.

For those times when the default browser was not up to the task, I installed Opera Mini. It certainly has come in very useful for keeping an the Cheshire East bus tracker and looking at any websites without mobile versions for when I decide to look at such things. Downloading any of these does take time and there’s the reality of navigating a big page on a small screen. However, I have discovered that the browser has an annoying tendency to crash and it did it once while I was awaiting a bus. The usual solution, rightly or wrongly, has been to delete the thing and reinstall it again with the time and device restarts that entails. While I got away with it once, it seems to mean losing whatever bookmarks or favourites that you have set up too, a real nuisance. Because of this, I am not going to depend on it as much any more. Am I alone in experiencing this type of behaviour?

Because of Opera’s instability, I decided on seeking alternative approaches. One of these was to set up bookmarks for the aforementioned bus tracker on Web ‘n’ Web. What is delivered in the WAP version of the site and it’s not that user friendly at all. When it comes to selecting a bus stop to monitor, it asks for a stance number. Only for my nous, I wouldn’t have been able to find the ID’s that I needed. That’s not brilliant but I worked around it to make things work for me. The observation is one for those who design mobile versions of websites for public use.

Another development is the discovery of Bolt Browser and, so far, it seems a worthy alternative to Opera Mini too. There are times when it lives up to the promise of faster web page loading but that is dependent on the strength of the transmission signal. A trial with the Met Office website showed it to be capable though there were occasions when site navigation wasn’t as smooth as it could have been. Up to now, there have been no crashes like what happened to Opera Mini so it looks promising. If there is any criticism, it is that it took me a while to realise how to save favourites (or bookmarks). While the others that I have used have a button on the screen for doing so, Bolt needs you to use the application menu. Other than that, the software seems worthy of further exploration.

All in all, surfing the mobile remains an area of continued exploration for me. Having found my feet with it, I remain on the lookout for other web browsers for the BlackBerry platform. It is true that OS 6 features a Webkit-powered browser but I’m not buying another device to find out how good that is. What I am after are alternatives that work on the device that I have. Porting of Firefox’s mobile edition would be worthwhile but its availability seems to be limited to Nokia’s handsets for now. Only time will reveal where things are going.

Worth the attention?

21st July 2010

The latest edition of Web Designer has features and tutorials on modern trends one new ways to use fonts and typography in websites. One thing that’s at the heart of the attention is the @font-face CSS selector. It’s what allows you to break away from the limitations of whatever fonts your visitors might have on their PC’s to use something available remotely.

In principle, that sounds a great idea but there are caveats. The first of these is the support for the @font-face selector in the first place though the modern browsers that I have tried seem to do reasonably OK on this score. These include the latest versions of Firefox, Internet Explorer, Opera and Chrome. The new fonts may render OK but there’s a short delay in the full loading of a web page. With Firefox, the rendering seems to treat the process like an interleaved image so you may see fonts from your own PC before the remote ones come into place, a not too ideal situation in my opinion. Also, I have found that this is more noticeable on the Linux variant of the browser than its Windows counterpart. Loading a page that is predominantly text is another scenario where you’ll see the behaviour more clearly. Having a sizeable image file loading seems to make things less noticeable. Otherwise, you may see a short delay to the loading of a web page because the fonts have to be downloaded first. Opera is a particular offender here with IE8 loading things quite quickly and Chrome not being too bad either.

In the main, I have been using Google’s Fonts Directory but, in the interests of supposedly getting a better response, I tried using font files stored on a test web server only to discover that there was more of a lag with the fonts on the web server. While I do not know what Google has done with their set up, using their font delivery service appears to deliver better performance in my testing so it’ll be my choice for now. There’s Typekit too but I’ll be hanging onto to my money in the light of my recent experiences.

After my brush with remote font loading, I am inclined to wonder if the current hype about fonts applied using the @font-face directive is deserved until browsers get better and faster at loading them. As things stand, they may be better than before but the jury’s still out for me with Firefox’s rendering being a particular irritant. Of course, things can get better…
