Firefox extension not compatible with browser (Flock, Mozilla, Seamonkey…) version: What to do?

October 22nd, 2007

You really want to install this Firefox extension but you can’t? Because it’s not compatible with your browser (screen shot)? Or you have upgraded your browser and some of your favourite add-ons got disabled? Happens a lot with more exotic extensions, or if you’re using a minority browser like Seamonkey, (the old) Mozilla, or (the brand new) Flock. However, you do not need to despair: (more…)

Delegation discovery: a bookmarklet for OpenID evangelists

October 10th, 2007

There’s little to add to the many great writeups, presentations and screencasts on OpenID, but I thought it would be fun to have a bookmarklet that checks whether a page URL can be used as an OpenID login, so whether that page already has been “claimed”. (more…)

Master of your mailbox: an email alias for every site you leave your address

October 9th, 2007

Do you want more control over which mails end up in your inbox? Then every time you give out your email address at a site, use an alias specific for that url. It helps you to track where (and by whom) mail addresses are being used, and lets you filter or block unnecessary mails. Here’s how: (more…)

Hosted screenscraping: HTML to RSS with Dapper

May 14th, 2007

There are several screen-scraping services out there, but Dapper is one that’s both versatile and visual. With a bit of trial and error, everyone can transform html web pages (or more precisely: changes in web pages) into email notifications, a startpage widget, RSS or another syndication format. Take this example: (more…)

Phone versus laptop lifestyle: Twitter for Alice and Bob

May 13th, 2007

Twitter is a lot of different things to a lot of different people, and at first, it can be difficult to get your head around. So, before I try to make my point on Twitter, let me introduce you to IM-Bob and SMS-Alice: (more…)

Free website monitoring services: montastic.com, mon.itor.us, internetvista.com

April 17th, 2007

There are several online services that warn you when your website is down or too slow. Here are three free services I tried (“free as in “freemium“). Feel free to add your findings or experiences… (more…)

Performancing.com user database ends up where it doesn’t belong

February 26th, 2007

I got an email from Mr. Robert Lo, Foreign Service Manager at Delixi Global Resources, based in Hong Kong. The sender was robertlo@shaw.ca, but the reply-to mail address was delixicompany_agent@yahoo.co.uk, the mail mentioned a website, but no website address was given, and the mail was not sent from Hong Kong, but from Alberta, Canada (ISP location via IP address). The most remarkable about this apparent job scam, was that they got my email address via the blogger community (and former blog statistics service and ad network) at performancing.com. (more…)

Why you were logged out of MyblogLog last night

February 23rd, 2007

You’re a Mybloglog user? Then you probably have had to log in again to have your avatar reappear at the blogs you visit. Some hours ago MyblogLog changed the way they place an identifier cookie at your harddisk. The reason: it was all too obvious how to take over someone else’s identity. More than a month ago, my fellow Belgian eMich (Michaël Uyttersprot) had already posted how to do this (I summarize his French-language post): (more…)

"Where is this domain hosted?" (web hosting location Firefox extensions)

February 16th, 2007

Yesterday’s post on locating an IP address also made me test the hostipfox (scroll down to halfway the page) and IP2LocationFox Firefox extensions. Both extensions let you look up the location where a website is hosted – just by pointing (and clicking). (more…)

IP to Location Bookmarklet

February 15th, 2007

You want to know more about a specific ip address in your log files or visitor statistics package? And you’re not satisfied with tools like whois or traceroute? There are several online services that use an ip range database to look up the location of an IP address (as far as this info is made available by the ISP). Here some bookmarklets to use two of them, Hostip.info and Ip2Location.com. (more…)

Adsense – image "association" no longer allowed (examples)

December 19th, 2006

Some publishers put images close to their Adsense units, in such a way that the image and the ad seem to be connected. Unsuspecting users try to click the image in vain, then try the link next to it, without noticing the link is part of an ad block. This trick to improve CTR (up to 4 times) was allowed by Adsense policies. As long as there was “a visible border between the ads and the images, to make it clear that the images are not being served by Google on behalf of the advertisers” (as quoted by Jensense). Was allowed, that is, until yesterday! (more…)
