A waiting game

Having been away every weekend in July, I was looking forward to a quiet one at home to start August. However, there was a problem with one of my websites hosted by Fasthosts that was set to occupy me for the weekend and a few weekday evenings afterwards.

The issue appeared to be slow site response so I followed advice given to me by second line support when this website displayed the same type of behaviour: upgrade from Apache 1.3 to 2.2 using the control panel. Unfortunately for me, that didn’t work smoothly at all and there seemed to be serious file loss as a result. Raising a ticket with the support desk only got me the answer that I had to wait for completion and I now have come to the conclusion that the migration process may have got stuck somewhere along the way. Maybe another ticket is in order.

There were a number of causes of the waiting that gave rise to the title of this post. Firstly, support for low costing isn’t exactly timely and I do wonder if it’s any better for more prominent websites. Restoration of websites by FTP is another activity that takes up plenty of time as does rebuilding databases and populating them with data. Lastly, there’s changing the DNS details for a website. In hindsight, there may be ways of reducing the time demands of these. For instance, contacting a support team by telephone may be quicker unless there is a massive queue awaiting attention and there was a wait of several hours one night when a security changeover affected a multitude of Fasthosts users. Of course, it is not a panacea at the best of times as we have known since all those stories began to do the rounds in the middle of the 1990′s. Doing regular backups would help the second though the ones that I was using for the restoration weren’t too bad at all. Nevertheless, they weren’t complete so there was unfinished business that required resolution later. The last of these is helped along by more regular PC restarts so that unexpected discovery will remain a lesson for the future though I don’t plan on moving websites around for a while. After all, getting DNS details propagated more quickly really is a big help.

While awaiting a response from Fasthosts, I began to ponder the idea of using an alternative provider. Perusal of the latest digital edition of .Net (I now subscribe to the non-paper edition so as to cut down on the clutter caused by having paper copies about the place) ensued before I decided to investigate the option of using Webfusion. Having decided to stick with shared hosting, I gave their Unlimited Linux option a go. For someone accustomed to monthly billing, it was unusual to see annual biannual and triannual payment schemes too. The first of these appears to be the default option so a little care and attention is needed if you want something else. In order to encourage you to stay with Webfusion longer, the per month is on sliding scale: the longer the period you buy, the lower the cost of a month’s hosting.

Once the account was set up, I added a database and set to the long process of uploading files from my local development site using FileZilla. Having got a MySQL backup from the Fasthosts site, I used the provided PHPMyAdmin interface to upload the data in pieces not exceeding the 8 MB file size limitation. It isn’t possible to connect remotely to the MySQL server using the likes of MySQL Administrator so I bear with this not so smooth process. SSH is another connection option that isn’t available but I never use it much on Fasthosts sites anyway. There were some questions to the support people along and the first of these got a timely answer though later ones took longer before I got an answer. Still, getting advice on the address of the test website was a big help while I was sorting out the DNS changeover.

Speaking of the latter, it took a little doing and not little poking around Webfusion’s FAQ’s before I made it happen. First, I tried using name servers that I found listed in one of the articles but this didn’t seem to achieve the end that I needed. Mind you, I would have seen the effects of this change a little earlier if I had rebooted my PC earlier than I did than I did but it didn’t occur to me at the time. In the end, I switched to using my domain provider’s name servers and added the required information to them to get things going. It was then that my website was back online in some fashion so I could any outstanding loose ends.

With the site essentially operating again, it was time to iron out the rough edges. The biggest of these was that MOD_REWRITE doesn’t seem to work the same on the Webfusion server like it does on the Fasthosts ones. This meant that I needed to use the SCRIPT_URI CGI variable instead of PATH_INFO in order to keep using clean URL’s for a PHP-powered photo gallery that I have. It took me a while to figure that out and I felt much better when I managed to get the results that I needed. However, I also took the chance to tidy up site addresses with redirections in my .htaccess file in an attempt to ensure that I lost no regular readers, something that I seem to have achieved with some success because one such visitor later commented on a new entry in the outdoors blog.

Once any remaining missing images were instated or references to them removed, it was then time to do a full backup for sake of safety. The first of these activities was yet another consumer while the second didn’t take so long and I need to do this more often in case anything happens. Hopefully though, the relocated site’s performance continues to be as solid as it is now.

The question as to what to do with the Fasthosts webspace remains outstanding. Currently, they are offering free upgrades to existing hosting packages so long as you commit for a year. After my recent experience, I cannot say that I’m so sure about doing that kind of thing. In fact, the observation leaves me wondering if instating that very extension was the cause of breaking my site. In fact, it appears that the migration from Apache 1.3 to 2.2 seems to have got stuck for whatever reason. Maybe another ticket should be raised but I am not decided on that yet. All in all, what happened to that Fasthosts website wasn’t the greatest of experiences but the service offered by Webfusion is rock solid thus far. While wondering if the service from Fasthosts wasn’t as good as it once was, I’ll keep an open mind and wait to see if my impressions changes over time.

Tinkering with Textpattern

Textpattern 5 may be on the way but that isn’t to say that work on the 4.x branch is completely stopped though it is less of a priority at the moment. After all, version 4.40 was slipped out not so long ago as a security release, a discovery that I made while giving a section of my outdoors website a spring refresh. During that activity, the TinyMCE plugin started to grate with its issuing of error messages in the form of dialogue boxes needing user input to get rid of them every time an article was opened or saved. Because of that nuisance, the guilty hak_tinymce plugin was ejected with joh_admin_ckeditor replacing it and bringing CKEditor into use for editing my Textpattern articles. It is working well though the narrow editing area is causing the editor toolbars to take up too much vertical space but you can resize the editor to solve this though it would be better if it could be made to remember those size settings.

Another find was atb_editarea, a plugin that colour codes (X)HTML, PHP and CSS by augmenting the standard text editing for pages and stylesheets in the Presentation part of the administration interface. If I had this at the start of my redesign, it would have made doing the needful that bit more user-friendly than the basic editing facilities that Textpattern offers by default. Of course, the tinkering never stops so there’s no such thing as finding something too late in the day for it to be useful.

Textpattern may not be getting the attention that some of its competitors are getting but it isn’t being neglected either; its users and developer community see to that. Saying that, it needs to get better at announcing new versions of the CMS so they don’t slip by the likes of me who isn’t looking all the time. With a major change of version number involved, curiosity is aroused as what is coming next. So far, Textpattern appears to be taking an evolutionary course and there’s a lot to be said for such an approach.

Changing to CKEditor from FCKEditor for WordPress Content Editing

The post editor that I have been using on my WordPress-powered outdoors blog has not been TinyMCE but FCKEditor. My use of that editor has meant that WordPress’ autosave and word counting features have not been available to me but that was my choice, as strange as it will sound to some. However, there have been times when I have missed the autosaving functionality and lost work. Since FCKEditor has been replaced by CKEditor, there are plugins available for adding that editor to WordPress’ administration interface. Recently, I got to replacing the old FCKEditor plugin with a newer CKEditor one and that has gained me post or page autosaving. The more cosmetic word counting feature is not active until a draft is manually saved but I can live with that. Other than that, the interface remains familiar with all (X)HTML tags on show in the source code view without any being hidden away from view like in WordPress’ implementation of TinyMCE. That isn’t to see that WordPress is doing something wrong but just that there are alternative way of doing things that are equally valid. After all, why would there be choices if there only ever was one right way to do anything?

Like any WordPress plugins, those replacing the default content editor in WordPress can be vulnerable to changes in the publishing platform and there is one of those in the pipeline for 3.2: a minimalist post/page editor that is billed as being non-distracting. That planned new feature is drawing inspiration from the likes of QuietWrite, where you can write content and transfer it over to WordPress or leave it where it was written. Even with bigger changes like this, my experience never has been that design decisions made for new WordPress releases have restricted to any great extent how I use the thing. That’s not to say that my usage hasn’t changed over time but I have felt that any decisions were mine to make and not all made for me. In that light, I can foresee CKEditor continuing to work on WordPress 3.2 but I’ll be doing some testing ahead of time to be sure that is the case.

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.

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.
