SMTP made, well, complex

If you’re at all like me, you move regularly between mutiple different networks: home, office, dialup, wifi hotspots, hotels, and, just now, any of the 15 or so wifi links I can see on the exhibition floor at LinuxWorld. For web browsing and reading mail this is normally fine, but when it comes to sending mail you often have to switch SMTP servers for each network you connect to. (This is because most ISPs only provide SMTP to machines on their network, as a spam-reduction measure. Move to another service provider and your home SMTP server probably won’t want to talk to you.)

There are ways around this. If you’re lucky enough to have an email server that supports authentication it’ll probably let you connect from anywhere, but not many do, and not all email clients support it.

I’ve found a solution which works well for me. If you have a machine somewhere that you can connect to using SSH, you can arrange to forward a port on your local machine over that link to whatever SMTP server that remote machine uses. Then you just tell your mail client to use ‘localhost’ as the SMTP server, regardless of which network you’re on. If you’re not familiar with SSH the details are a little tricky to describe here – email me for more info – but on OS X I’ve found a neat little app called SSHTunnelManager which makes it trivial to make and break the link.

ReturnPath

[Original Link] This is quite a good idea for a service. You register your past and present email addresses with them, and then when anybody goes to the site and types in one of your old addresses, you get notified and can choose whether or not they are given your new one. If it reaches a critical mass it will be very helpful, provided, of course, that they remain squeaky clean and are seen to be trustworthy.

If You Love Your Data, Set it Free

[Original Link] A highly abridged version of this article appeared in the IEE Review, Jan 2003. Unfortunately, as a result of the editorial process, significant typos and non-sequiturs were introduced, to the extent that I do not really wish to be associated with the published result. The original, however, makes much more sense and can be downloaded as a PDF here.

Lessig outvoted.

[Original Link] Bad news, this. A triumph of legal confusion and commercial influence over common sense.

TiVo gets Networked

[Original Link] I’ve been thinking about getting a TiVo for some time. This might push me over the edge.

A Microsoft Watch

[Original Link] Let’s hope it won’t have the Windows 95/98 bug that stops your machine after 6 weeks. Or the one which causes your date to leap forward or back a couple of days. Or the one which changes your time when you didn’t mean to. Or…

Having just returned home after a month away, I’m reading all my mail. You know, the old-fashioned sort that doesn’t follow you around the globe. One letter is a cheery note from my insurance company telling me that my home and contents aren’t insured against the consequences of (a) war, or (b) terrorism. This doesn’t bother me nearly so much as the fact that they felt the need to write and tell me….

Broadband Phone

[Original Link] Just discovered I have my name on
U.S. Design Patent D463,389. After two and a half years I had forgotten it was even in progress. Not sure what good it is; it’s sort of like a regular patent without the claims… 🙂 And prettier pictures of the Broadband Phone can be found here.

Thought for the day

Cicero said, “Not to have knowledge of what happened before you were born is to be condemned to live forever as a child”.

I guess this applies to companies as well as to people.

A tale of Two Towers

Well, yesterday I saw the second film in the Lord of The Rings series and it was, if anything, better than the first; quite an achievement. Making the middle film in any trilogy must be hard, and especially following the spectacular success of the first.

At a time when Hollywood is turning out an even higher percentage of complete rubbish than usual (as amply demonstrated by the trailers which preceded the Two Towers last night) it is encouraging that a few movies are still being made with love, care and very great skill.

If the Return of The King turns out to be as good as the first two, and there’s no reason why it shouldn’t, then I think one could make a good argument for this being the greatest cinematic achievement of all time. It certainly puts to shame all of the recent special-effects-only ‘blockbusters’ (Titanic & the Star Wars sequels, for example), and while other films have had more subtlety or art, I can’t think of anything that has combined them with a production of this scale.

The best way to appreciate the scale, by the way, is by watching some of the commentaries and documentaries on the extended-edition DVD of the first film, which in turn is probably the best use of that medium that I’ve yet come across.

Reading the above, by the way, might make you think that I’m something of a Tolkien fanatic. I’m not, but I’m in danger of becoming a Peter Jackson fanatic. Thank God it didn’t go to Disney or Spielberg.

Creative Commons

[Original Link] About a week ago, Creative Commons launched the first version of their licensing project.

It’s a well-designed site. They explain the licences clearly in non-legal jargon and have a form where you can say what you want to do with your work and they suggest the appropriate licence. And all of this is just pretty icing on the exceedingly important underlying work.

I’ll be adopting one of their licences for everything on this site in the near future.
