Verity Stob’s Web 2.0 app diagram is worth a look.
So is it back to plain old HTML+forms then? That won’t do either; your app will look a decade old, and offline will never work.
This is why the current RIA wars are fascinating – particularly since Apple seems averse to runtimes like Flash, Java or Silverlight on its iPhone.
Which leaves what? JavaScript, hélas.
An interesting facet of the recent problems with UK non-supplier Zavvi Direct is that all the purchasers I spoke to found the fake web site via a Google ad. Put another way, without the ease of advertising through Google and eBay, it is likely that far fewer people would have found the site and potentially lost their money.
That raises the question: does Google do anything to verify that its advertisers are genuine? Here’s the answer, from a Google spokesperson:
Google, along with other online and offline advertising platforms are not able to proactively check the legitimacy of each and every advertiser. Consumers should always check the validity of what is being sold to them and how they are asked to pay for items. If Google is alerted to a potential fraud then we will work with the relevant legal authorities to help them resolve such matters.
This was clarified to me as follows. Google will assume ads are OK unless it receives complaints. If it receives a few complaints it might pass them on to the merchant. If it receives numerous complaints it might warn the advertiser and eventually disable the account.
I guess it is unreasonable to expect Google to conduct checks on every advertiser. Still, there is a related point: does Google do enough to highlight the difference between advertisements, and links identified by its famous search ranking algorithms? Here is a snapshot of a search I just made:
I’ve sized the browser small to get everything in; there are more search results than I’ve shown. However, it shows three panels of results. The top left is tinted and marked in unobtrusive gray type “Sponsored links”. The top right is narrow, not tinted, and also marked in gray type “Sponsored links”. The bottom left is what most tech-savvy folk think of as the main results area.
Judging by my interviews, some people are not really aware of the distinction between a “sponsored link” and a search result. In some cases, the buyer could not tell me what kind of link they clicked. To them it was just “Google”.
It would be easy to make the ads more distinct. Google could use the plain English “Advertisements” rather than the “sponsored links” circumlocution. It could use something bolder than gray text to identify them. It could use a different font and colour for the links in the right-hand column. It is good that the top left links are in a tinted panel; yet some may perceive this simply as best-match links, rather than links in an entirely different category than those that follow.
Overall, it seems to me that Google deliberately makes its ads look the same as search results. Which is good for advertisers, but can be bad news for buyers.
I’ve just listed an MP3 player for sale on eBay in the UK. I was surprised to see that I was required to accept PayPal and only PayPal for the transaction, making the “Decide how you’d like to be paid” section of the form redundant:
It is not even possible to state that someone who collects personally may pay cash.
As I understand it, eBay is not applying this rule to all transactions. I suspect this one is regarded as higher risk because it is electronics. The company justifies it on the grounds of security; but since eBay owns PayPal, and gets a double-dip on the fees for transactions processed by PayPal, it has other incentives.
I don’t like this. It is a step backwards; I prefer to have control over what payments are acceptable. I still listed it though, since Amazon (the obvious alternative) is even more expensive, and also acts as payment provider.
eBay has run into some trouble over this policy in Australia; I wonder if the UK will make a similar fuss?
Update: I’ve discovered that eBay UK is now forbidding payments other than PayPal on the following types of sale:
1) Sellers using a 1-day listing format
2) Sellers listing in these categories:
– Video Games > Consoles
– Consumer Electronics > MP3 Players
– Computing > Software
– Wholesale & Job Lots > Mobile & Home Phones
– Business, Office & Industrial > Industrial Supply/ MRO
There are some broad categories there. Further, I presume that once eBay starts restricting some sales to PayPal only, it will be tempted to extend the list further.
Not a pictorial version of Esperanto; rather, a set of design guidelines for bbc.co.uk:
The global visual language is a set of guidelines which aim to bring more consistency to the site by introducing an underlying design grid and consistent design patterns, icons, buttons, image sizes and a pan-BBC audio/video player.
according to BBC interaction designer and blogger Ben Hanbury. His main focus is the revised iPlayer site, which has the last seven days of the BBC’s TV and radio output available on-demand via a media player based on Flash – Adobe must be delighted.
That said, the new iPlayer site is one of the few examples I’ve known where Flash content does not play reliably. On my normal PC I get the useless and inaccurate message, “This content isn’t available at the moment.” Seems to be a firewall issue. I’ll post again if I can work out exactly what the problem is.
The team behind the open source SCM (Software Configuration Management) tool Subversion released version 1.50 last month. Karl Fogel, president of the Subversion Corporation, says:
Measuring by new features alone, Subversion 1.5 is our biggest release since version 1.0 became available in February 2004.
I am a contented Subversion user, so took a look at the changes. Top of the list is “merge tracking”, though it is described as “foundational” which means that although the basic support is there, there is performance and feature work which remains to be done. From the user’s perspective, the difference is that branching and merging is just easier than before, as explained by Ben Sussman:
Notice how I never had to type a single revision number in my example: Subversion 1.5 knows when the branch was created, which changes need to be synced from branch to trunk, and which changes need to be merged back into the trunk when I’m done. It’s all magic now. This is how it should have been in the first place.
Other changes include sparse checkouts (when you only want to grab a small part of a repository), and changelists, a client feature which lets you tag a set of files under a changelist name and work on them as a group. There are also improvements aimed at making Subversion better suited to large-scale deployments using multiple servers. Subversion is still a centralized rather than a distributed SCM system, but 1.5 is better suited for use in a distributed manner. No doubt the Subversion team is aware of the increasing interest in Git, a distributed system. There are also numerous bug-fixes and performance tweaks. The changes are described here.
I want to move to Subversion 1.5 but it is not that easy. Compatibility is good, in that older clients work with 1.5 servers and vice versa, the main proviso being that you cannot mix several versions of the Subversion client with the same working copy. That is not likely to be a problem for most users.
The difficulty I encountered is that mainstream Linux distributions still have older versions of Subversion in their stable repositories. Ubuntu, for example, has version 1.4.4. My most-used Subversion repositories are on a Debian server, which also has an old version. I don’t want to switch the server to sid, Debian’s development distribution, and mixing packages is often problematic. I could do a manual installation I guess; but instead I will be patient.
I did install 1.50 on Windows, for an intranet repository. I used the Collabnet download. All I needed to do was to inform the installer of the location of my existing repository, and then copy a few lines from the old Apache 2.0 configuration file to the new Apache 2.2 configuration file. Everything works fine. I also updated TortoiseSVN on the Windows clients.
One of the advantages of Subversion (or any SCM) repositories over synched folders like those in Microsoft’s Live Mesh or Apple’s MobileMe (as I understand it) is that you get version history. I regard this as a key feature. The problem with synchronization is that you might overwrite a good copy with a bad one. It is easy to do; it might be caused by user error, or a bug in your word processor, or a failing hard drive. Automatic synch (un)helpfully replicates the bad copy all over. Versioning means you can just rollback to the good one.
Interesting post from Lisa Underkoffler’s on what’s coming in Buzzword, Adobe’s internet word processor. She mentions named styles, which I would enjoy since I use these all the time in Word; though I was surprised that it is frequently requested; most people seem happy to apply specific formatting and don’t worry about the structure provided it looks right. Maybe this is Adobe’s strong presence in the print and publishing world showing through.
It prompted me to make a quick tour of the competition to see who already has named style support. Nothing I could see in Google Docs.
Zoho Writer doesn’t seem to have them either.* Zoho’s site also seems a bit temperamental this morning. The connection kept failing which meant a long wait while, perhaps, some AJAX operation was not completing. Zoho froze IE completely; I switched to FireFox but it remained slow. I wish the Zoho folk would stop adding features (even named styles) and focus on performance and reliability for a while; perhaps it is better in the USA.
ThinkFree has them, and they seemed to work (more or less) once I had downloaded its gargantuan Java applet. The company seems to be shifting the emphasis to a downloadable application with online storage, perhaps because the applet is too big for casual use on any old computer. I tried the downloaded application as well. Curiously, after I saved and re-opened the document, my named style disappeared from the list of styles. I think something is not quite right here; I also had a few performance issues.
If you are happy to run a desktop application, Word plus Live Mesh makes a decent and familiar alternative. Just save your document to the Mesh, and open it from anywhere. Main snags: no Mac or Linux support yet, no online editing.
I’ve actually fallen into the habit of using Live Writer plus WordPress as a kind of cloud word processor. Writer has a feature called Post Draft to Weblog. Your document is saved to your blog, but not actually published. Usually I do this for posts that will be published later; but sometimes I use it for notes that will never be published. I can open the draft later from another PC using Writer; or use the online editor in WordPress if Writer is not installed. Another option is to save the draft locally, handy if you are offline; Live Writer will synch it with the online version later. Not recommended for confidential documents, but for casual use it is a powerful combination.
No named styles though. Never mind.
*Update: See comment below: Zoho does support CSS. So if you have a CSS stylesheet set up, you could use these styles in your document. Good idea, though I’m not sure how you go about using this if you are not a skilled web developer.
Microsoft’s Richard Florance has a neat set of “easy win” performance tips.
Long Zheng’s Windows UX Taskforce is notable for several reasons. Zheng devised the site in order to give Microsoft feedback on quirks and annoyances in the Windows Vista user interface. He hid it by designing an application that lets users promote or demote user reports, Digg-style. To give you an idea, top of the list right now is that bewildering dialog that appears when trying to safely remove a USB thumb drive card reader – with 262 votes.
So the site is notable, first, for what it says about the Windows Vista UI; second, for what it says about the number of people who care about it and are willing to submit detailed feedback; and third, because it shows what a great way this is for managing bug reports and feature requests.
Actually, Microsoft already has something along these lines, called Connect. It’s fascinating to contrast Zheng’s quickly-assembled but easy to use site, which is attracting lots of users, with Microsoft’s site that is slower, more complex, and less compelling. It’s incomplete too. How do I submit feedback for Microsoft Word, for example?
It strikes me that software vendors have just been shown a simple and effective way to improve their products. I wonder how many will take it up?
I spent a couple of hours putting together a simple CRUD (Create, Retrieve, Update, Delete) application with Silverlight 2.0 beta 2.
Most of the examples I’ve seen use LINQ to SQL; that’s fine, but I wanted to do something without that intermediate layer. Having said that, I ended up in effect writing my own object-relational mapper. Still, it’s nice to know exactly what the code is doing.
I predicted in April that Britannica would add user-generated content.
Now it is doing so, according to Wired.
