A spot of extension bother with Firefox

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

Turning off the admin bar in WordPress 3.1

Work on WordPress 3.1 is in full swing at the moment though I initially though that they were taking a little break after 3.0. From what I can see, many refinements are being made to the multi-blog functionality and behind-the-scenes work is ongoing on the administration screens too.

Another under-the-bonnet change has been to make WordPress less tied to MySQL since the possibility of dropping in support for an alternative such as PostgreSQL is now a reality even if it isn’t part of the default package. For now, it looks as if this is going to be plugin territory rather than default multi-database support though that may become a sensible development in the light of Oracle’s acquisition of MySQL and its sabre rattling with regard to Java patents. So far, the change to WordPress has affected my use of its database engine to power an offline version of my online photo gallery but a quick spot of code editing sorted that issue.

One more obvious alteration is going to be the addition of a WordPress.com style administration bar to the top of all content and administration screens for a user who is logged into the system. It is going to be turned on by default but there will be the option of turning it off for those among who prefer things that way. All that will be needed for this is to add the following line near the top of wp-config.php:

define( “WP_SHOW_ADMIN_BAR”, false);

The chance to see new additions like those above and be ready for is my main reason for following WordPress development. It’s best to be ready than surprised though it has to be said that the blogging or CMS platform is a very polished one these days.

On web browsers for BlackBerry devices

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.

Exploring the mobile web

With a change of job ahead of me, I decided to make my web usage a little more mobile. The result was the purchase of a Blackberry 8520 Curve on a T-Mobile pay-as-you-go tariff to complement my existing phone. Part of the attraction was having email on the move and a little web access too. On both accounts it hasn’t though GPRS isn’t the speediest for web browsing and you get to appreciating mobile versions of websites. It’s just as well that this website that you’re reading has a mobile version.

Hooking the Blackberry up to GMail was no problem once I had paid my dues and the necessary set up was done for me; it was only then that the required option was available through the set up screens. RIM’s own web browser may be no slouch when it comes to rendering websites but I put Opera Mini in place as well for those times when the default option could be bettered and they exist too. Speaking of RIM applications, there’s one for Twitter too though I added Übertwitter for sake of greater flexibility (it can handle more than one account at a time, for example). In addition, I have instated applications for WordPress and LinkedIn too and it was then that I stopped myself spending too much time in Blackberry App World. If I was of the Facebook persuasion, I might be interested in the default offering for that as well but I have learnt to contain myself.

Of course, there are limitations to the device’s capabilities with regards to email and web on the move. Long emails still need desktop access (messages can get truncated) and mobile unfriendly websites will take an age to load and explore; a small screen means much more finger work. After all, this is a small device so the observations aren’t really surprising; it’s just that I encounter the reality of life on a small screen now. Nevertheless, useful site like those from Google and the Met Office have a mobile variant though I’d like to see the latter including its rain radar as part of the package.

Speaking of life on a smaller scale, there’s the size of the keyboard to consider too. So far, I haven’t had much practice with it but I am unsure as how some craft longer blog entries with the the tiny keys. Then, there’s the ever-present threat of arm discomfort and RSI that you have to watch. For that reason, I’ll stick with use for an hour at a time rather than going mad altogether. Navigating around the screen using the tiny trackpad is something to which I am adjusting and it works well enough too so long as you’re not looking through long web pages or emails.

To bring this piece to a close, the new gadget has been finding uses and I don’t plan on leaving it idle after paying over £150 for it. Apart from acting as an expensive calculator, it has already travelled abroad with me with roaming not being a problem; I may have failed to get it to work with hotel broadband but there was EDGE availability to keep things connected together. All in all, the device is earning its keep and teaching me a few things about mobile handheld computing with my main website in process of being made more mobile compatible with the front page and the photo gallery gaining versions for handheld devices after the same was done for the outdoors blog earlier this year (might make the design look more like the rest of the site though). Without something on which to do some real testing, that idea may not have become reality like it is. It may be no desktop substitute but that’s never to say that these devices may never get near that situation. After all, there was a time when no one could imagine the same for laptop PC’s and we all know what has happened with them.

Removing a column from a MySQL data table

My trying out WordPress 3.0 in advance of its final release has brought me errors on the links management page. After a spot of poking around the TRAC, I found that the bug already has been reported and that the cause is an extraneous column in the *_links table called link_category. The change in taxonomy handling over the years seems to have made it redundant so I removed the said column from the database using a command like the following from both the MySQL command line and MySQL Query Browser:

alter table wordpress.wp_links drop link_category;

That seems to have made those errors go away and I hop that their upgrade code takes care of this before WordPress 3.0 is let loose of the general blogging public. Taking out the coding brittleness would do too.

Sometimes it’s a small change that matters…

Firefox 3.6 is now available and others are going on about more striking features but it’s small change that I have noticed and it happens to be a good one too. Middle clicking on a link in tab used to open a new one at the right hand of the tab bar. Now, the new tab opens next to the one where the click was clicked and that’s a good thing if you are previewing blog posts. It was something that Internet Explorer already did so it’s good to see cross-fertilisation of useful features; yes, Microsoft can come up with good ones too from time to time. Though not likely to make major headlines, this is the type of thing that makes for better user experience and a few of them together can be more beneficial than some big shiny new feature. In life, it’s often the little things that make all the difference.
