There is one thing that doesn’t upset me a half as much as it should, likely because I’m almost never involved in end-user software development nowadays (although it can be found in back-end software as well): feature-by-feature “ports” (or rather, re-implementations).
Say there is a hugely-known, widely-used proprietary software, and lots of people feel like that a free alternative to that software is needed (which happens pretty often, to be honest, and is the driving force for the Free Software movement, in my opinion); you have two main roads, among a gazillion of possible choices, that you can take: you try to focus on the the use cases for the software or you can re-implement it feature-by-feature. I learnt, through experience, that the former case is always better than the latter.
When I talk about experience, I don’t mean the user experience but rather the actual experience of coding such ports. A long time ago, one of my first projects with Qt (3) under Linux was a try at porting the ClrMame Pro tool (for Windows) — Interestingly enough, I cannot find the homepage of the tool on Google, I rather get the usual spam trap links from the search. My reason to try re-implementing that software, at the time, was that I used to be a huge MAME player (with just a couple of ROMs) and that the program didn’t work fine under Wine (and the few tries I took at fixing Wine didn’t work out as well as I’d have hoped — yet I think a few of my patches made it through to Wine, although I doubt the code persists today).
Feature-by-feature porting is usually far from easy, especially for closed-source applications, because you try to deduce the internal working from the external interface (be it user interface or programming interface) and that rarely works out as good as you would like. Given this is often called reinventing the wheel, you should consider this like trying to reinvent the wheel after being given just a cart without wheels, looking at the way they should connect. For open source software, this is obviously easier to do.
Now, while there are so many software out there that make the same mistake, I’d like to look first at one that, luckily, ended up breaking off from the feature-by-feature idea and started working on a different method, albeit slowly and still being tied too much, in my opinion, to the original concept: Evolution. Those who used the first few versions of Evolution might remember that it clearly, and unbearably tried to imitate, feature-by-feature, Microsoft Outlook 2000. The same icon pane on the left-side, same format for the contacts’ summary, and same modules. The result is … not too appealing, I’d say. As I said the original concept creeps in today as well, as you still have essentially the same modules: mail, contacts, calendar, tasks and notes, the last two being those that I find quite pointless today (especially considering the presence of Tomboy and GNote). A similar design can be found in KDE’s Kontact “shell” around the separated components of the PIM package.
On the other hand, I’d like to pick up a different, proprietary effort: Apple’s own PIM suite. While they tend to integrate their stuff quite tightly, they also have taken a quite different approach for their own programs: Apple’s Mail, iCal and Address Book. They are three different applications, they share the information they store, one with the other (so that you can send and receive meeting invites through Mail, picking up the contacts’ emails), but they have widely different, sometimes inconsistent interface when you put one near the other. On the other hand, each interface seem to have its sense, and in my opinion ends up faring pretty well on the usability scale. What it does not try to do is what Microsoft did, that is forcing the same base graphical interface over a bunch of widely different use cases.
It shouldn’t then surprise that the other case of feature-by-feature (or in this case, misfeature-by-misfeature) port, is again attached to Microsoft from the “origin” end: OpenOffice. Of course, it is true that the original implementation for it comes from a different product (StarOffice) that didn’t really have the kind of “get the same” approach that Evolution and other projects have taken, I guess. On the other hand, they seem to keep going that way, at least to me.
The misfeature that brought me to write this post today is a very common one: automatic hyperlink transformation of URLs and email addresses… especially email addresses. If I consider the main target result from OpenOffice, I’d expect printed material (communications, invoices, and so on) should be up on the top. And in that kind of products you definitely don’t need, nor want, those things hyperlinked; they would not be useful and would be mostly unusable. Even if you do produce PDFs out if it (which supports hyperlinks), I don’t think that just hyperlinking everything with an at-character on it would be a sane choice. As I have been made aware, one of the most likely reason for OpenOffice to do that is that… Word does. But why does Word in the first place?
It’s probably either of two. At the time of Office 2000 (or was it 97? I said 97 before on identi.ca, but thinking for a bit, it might have been 2000 instead), Microsoft tried to push Word as a “web editor”: the first amateur websites started to crop around, and FrontPage was still considered much more top-level than Word; having auto-hyperlinking there was obviously needed. The other option is about the same time, when Microsoft tried to push Word as … Outlook’s mail editor (do you remember the time when you received mail from corporate contacts that was only an attached .doc file?).
So in general, the fact that any other software has a feature does not really justify implementing some feature on a new one. Find why the feature would be useful, and then consider it again.
