WET11 ethernet bridge & DHCP

This will be of little interest to most people, but somebody may find it on Google and be grateful! I have seen a few queries about this out there, and I’ve hit the problem twice recently, so I thought it worth posting.

If you a have a WET11 wirless ethernet bridge or similar product, and you’re having problems getting DHCP to work across it, it may be that your DHCP client is not setting the ‘broadcast bit’ in its DHCP query. I fixed this on my Linux DHCP server by adding:

always-broadcast on;

at the appropriate point in /etc/dhcpd.conf. See the dhcpd.conf man page for more info.

Right of reply

[Original Link] If I criticise you in my blog, you may soon be able to demand the right of reply. Perhaps. An article by Declan McCullagh is causing some concern on Slashdot, where they’re wondering what would happen if Microsoft decided to respond to every criticism!

Still, this is only in Europe and may not be enforceable even here. I wonder if adding an unmoderated ‘comments’ feature to a blog would be enough to satisfy the legislation?

Free speech

[Original Link] Dave Winer hits on what is, for me, a key attraction of weblogs:

“On my weblog no one can change what I wrote. In contrast, having written for professional publications, pros have to prepare for their writing being interfered with. Sometimes you submit right at the copy-edit deadline. Or you write exactly the required number of words so nothing can be cut. But in the end, the words that appear are an amalgam of what your organization thought should be said on the subject you’re addressing.”

Exactly this has happened to me, most recently writing for the Communications of the ACM and the IEE Review. The dear old CACM, for example, objected to my use of the phrase “three score years and ten”, presumably as requiring too much education on the part of its readers. Sad to see such dumbing down in what used to be an academic journal. They admitted it, too, though with the qualifier, “…we call it ‘mainstreaming'”.

The Review editors, on the other hand, introduced typos, while cutting out entire paragraphs, with the result that I appeared to be arguing the opposite point from my intended one, and doing so incompetently. This was done at the last minute, of course, after I had approved another version.

In both of these cases, it’s only really my wounded pride that bothers me, because despite their large distribution numbers, I doubt very many people actually read that sort of journal any more. I care less about the mangling of my words than that my name is still associated with them afterwards! I make lots of mistakes and stylistic errors too, of course, but at least here I can fix them before too many people notice.

Zen Garden

[Original Link] Dave Shea’s ‘Zen Garden’ is a wonderful demonstration of the power of CSS. Recommended for anybody who designs web sites. [link from Scripting News]

I’ve just been doing a (much less ambitious) web site. Since it’s been a while since I last did any substantial HTML coding, I’ve been finding it a real joy to use CSS with the realistic expectation that almost all of the intended audience will be able to see the results as I intended.

The Bluetooth truth hurts

[Original Link] David Berlind tells it like it is. Bluetooth is great when it works, but more often than not, it doesn’t. One of the follow-up comments says, “Bluetooth is destined to be the Edsel of IT…”. And another, “…at some point we have to take stock and decide whether it is worthwhile to continue investing in an architecture that has taken so long to deliver so little”. Sad, but true. It works flawlessly for me but only in one specific situation: connecting my Mac to one of the small number of Apple-approved Ericsson phones.

I’ve written about this before: I linked to an osOpinions article and also to a BusinessWeek article, among others. The BW article has now disappeared behind a pay-for-access barrier. So I’m likely to link to them in future about as often as I try linking to my Bluetooth headset.
