If all else fails…

Two problems have come my way that were resolved by removing configuration files and going again. Both affected Linux installations that I have. The Ubuntu installation on my main PC is working well but I ran into trouble starting up NetBeans 6.8. No GUI would ever appear but taking away the .netbeans folder from my home area allowed a fresh start with the IDE starting up as it should. To date, not all of the various projects that I have are restored but that can be done as I go along. Plugins for PHP development needing reinstatement but that was another easy thing to achieve; just go to Tools>Plugins on the menus and work with the dialogue box that appears to download and install the needful.

The inspiration for taking the configuration folder from the home area came from needing to address a misadventure with a Debian VM. Perhaps foolishly, I went using gconf-editor on there and messed up the appearance of the terminal window with whatever change I made. Getting rid of the .gconf folder restored order with its recreation by the system. Next time, remembering what changes have been made and reversing them might be the best course of action…

Upgrading to Fedora 13

After having a spin of Fedora’s latest in a Virtualbox virtual machine on my main home PC, I decided to upgrade my Fedora box. First, I needed to battle imperfect Internet speeds to get an ISO image that I could burn to a DVD. Once that was in place, I rebooted the Fedora machine using the DVD and chose the upgrade option to avoid bringing a major upheaval upon myself. You need the full DVD for this because only a full installation is available from Live ISO images and CD’s.

All was graphical easiness and I got back into Fedora again without a hitch. Along with other bits and pieces, MySQL, PHP and Apache are working as before. If there was any glitch, it was with Netbeans 6.8 because the upgrade from the previous version didn’t seem to be a complete as hoped. However, it was nothing that an update of the open source variant of Java and Netbeans itself couldn’t resolve. There may have been untidy poking around before the solution was found but all has been well since then.

When buttons stop working…

One of the things that stopped working as it should after my recent Ubuntu 9.10 upgrade was the Eclipse PDT installation that I had in place. Editing files went a bit haywire and creating projects had me pushing buttons with nothing happening. Whether this was a Java or GNOME issue, I don’t know but I found it happening too on openSUSE 11.2 (there should be more on that distro in a later entry). That was enough to get me looking again at Netbeans.

In both openSUSE (NB version 6.5) and Ubuntu (NB version 6.7.1), I plucked the default offering of Netbeans from the respective software repositories and added the PHP plugin in both cases. Unlike when I last gave the platform a go, things seemed to go smoothly and it looks to have replaced Eclipse for PHP development duties. Project scanning make take a little while but it’s far from annoying and my earlier dalliance with using Netbeans as a PHP editor was stymied by performance that was so sluggish as to make the thing a pain to use. Up to now, Netbeans’ footprints when it comes to its use of PC power never was light so I am wondering if dual-core and quad-core CPU’s help along with a copious supply of RAM. Only time will tell if these inital positive impressions stay the course and I’ll be keeping an open mind for now.

Are ten seconds enough?

Fasthosts, the hosting provider for what you find here has, in their wisdom, decided to limit the execution time for ASP scripts to 15 seconds and 10 seconds for any others. I haven’t used Perl sufficiently in this shared hosting set up to determine how that is affected. In contrast, I can share my experiences on the PHP side and you may have noticed occasional glitches. They have also disabled the set_time_limit PHP function so you cannot easily address the matter yourself where you need to do it. You almost get the feeling that they don’t trust the abilities, actions and oversight of their users. Personally, I reckon that the ten second limit is too short and that something of the order of 20 or 30 seconds would be better. If it all gets too restrictive, I suppose that there are other providers though I think that I would avoid resellers after a previous less than glorious experience. There’s the dedicated server option too if I was feeling flush, not so likely given the economic times in which we live.

Self-hosted web analytics tracking

It amazes me now to think how little tracking I used to do on my various web “experiments” only a few short years ago. However, there was a time when a mere web counter, perhaps displayed on web pages themselves, was enough to yield some level of satisfaction, or dissatisfaction in many a case. Things have come a long way since then and we now seem to have analytics packages all around us. In fact, we don’t even have to dig into our pockets to get our hands on the means to peruse this sort of information either.

At this point, I need to admit that I am known to make use of a few simultaneously but thoughts about reducing their number are coming to mind but there’ll be more on that later. Given that this site is hosted using WordPress software, it should come as no surprise that Automattic’s own plugin has been set into action to see how things are going. The main focus is on the total number of visits by day, week and month with a breakdown showing what pages are doing well as well as an indication of how people came to the site and what links they followed while there. Don’t go expecting details of your visitors like the software that they are using and the country where they are accessing the site with this minimalist option and satisfaction should head your way.

There is next to no way of discussing the subject of website analytics without mentioning Google’s comprehensive offering in the area. You have to admit that it’s comprehensive with perhaps the only bugbear being the lack of live tracking. That need has been addressed very effectively by Woopra, even if its WordPress plugin will not work with IE6. Otherwise, you need the desktop application (being written in Java, it’s a cross-platform affair and I have had it going in both Windows and Linux) but that works well too. Apart maybe from the lack of campaigns, Woopra supplies as good as all of the information that its main competitor provides. It certainly doe what I would need from it.

However, while they can be free as in beer, there are a some costs associated with using using external services like Google Analytics and Woopra. Their means of tracking your web pages for you is by executing a piece of JavaScript that needs to be added to every page. If you have everything set to use a common header or footer page, that shouldn’t be too laborious and there are plugins for publishing platforms like WordPress too. This way of working means that if anyone has JavaScript disabled or decides not to enable JavaScript for the requisite hosts while using the NoScript extension with Firefox, then your numbers are scuppered. Saying that, the same concerns probably any JavaScript code that you may want to execute but there’s another cost again: the calls to external websites can, even with the best attention in the world, slow down the loading of your own pages. Not only is additional JavaScript being run but there also is the latency caused by servers having to communicate across the web.

A self-hosted analytics package would avoid the latter and I found one recently through Lifehacker. Amazingly, it has been around for a while and I hadn’t known about it but I can’t say that I was actively looking for it either. Piwik, formerly known as PHPMyVisites, is the name of my discovery and it seems not too immature either. In fact, I’d venture that it does next to everything that Google Analytics does. While I’d prefer that it used PHP, JavaScript is its means of tracking web pages too. Nevertheless, page loading is still faster than with Google Analytics and/or Woopra and Firefox/NoScript users would only have to allow JavaScript for one site too. If you have had experience with installing PHP/MySQL powered publishing platforms like WordPress, Textpattern and such like, then putting Piwik in place is no ordeal. You may find yourself changing folder access but uploading of the required files, the specification of database credentials and adding an administration user is all fairly standard stuff. I have the thing tracking this edifice as well as my outdoor activities (hillwalking/cycling/photography) web presence and I cannot say that I have any complaints so we’ll see how it goes from here.

A new feature request for Textpattern?

Having been doing some updates to articles in A Wanderer’s Miscellany, an idea that makes life easier when working in Textpattern with old articles has come to mind. Currently, there is no way to navigate through pages in the administration area other than using the search or previous/next functionality. I have gotten to thinking that being able to subset articles by section or category using drop down menus would be a good way forward. A search for a suitable plugin was set in train but it yielded nothing of immediate use (amazingly, no one has given it a go thus far), hence the thinking regarding a new feature request. There is a place on the Txp support forum for exactly this kind of thing and I am in the throes of plucking up the courage to go for it. Apparently, some code cutting of my own would grease the wheels for the progression of any such thing but I remain unsure as to how far I want to go down that route so a bare request might be what they get. Moving to an alternative platform might be an alternative proposition but I see little reason in doing so when what I have otherwise works well for what I want it to do. That Textpattern feature request might just come into being…
