Veilig betalingsverkeer in Nederland: een gezamenlijke verantwoordelijkheid

Picture 1.png De banken beheren uw geld. Veiligheid staat daarbij voorop. Of het nu gaat om uw betaalrekening of uw spaartegoed, om internetbankieren of uw PINpas. Meestal gaat dat goed. Maar criminelen zoeken altijd naar nieuwe manieren om onze klanten te duperen. De banken zijn daar heel alert op en passen hun systemen en procedures daar continu op aan. Om te voorkomen dat uw gegevens toch worden misbruikt, is het belangrijk dat u weet welke maatregelen de banken nemen, welke manieren criminelen gebruiken en hoe u dat voor kunt zijn. Op deze website leest u daar meer over. Een veilig betalingsverkeer is een zaak van ons allemaal.

Google trends, a product in development

labs_logo2.gif Google trends, one of the new beta products of the Google Labs, is a tool that visualises how many times a topic has been searched for on Google. How does it work? "Google Trends analyzes a portion of Google web searches to compute how many searches have been done for the terms you enter relative to the total number of searches done on Google over time. We then show you a graph with the results -- our search-volume graph." Hm, sounds vague. So I tried it out with the topics 'information management' and 'knowledge management'. The result is a beautifull visual which in facts tells me little. It shows that the topic 'information management' is entered more frequently than 'knowledge management'. That knowledge management is not mentioned in Google news over the last three years. At least not enough to show up in Google trends. Right.

So I tried a different one. Ajax and Web 2.0. With the combination of the two topics I hoped to filter out the other Ajaxes, amongst them the populair footbalclub of Amsterdam. Alas, the results are not usable. In the overview of news only one of the six results mentioned the Ajax I was searching for. The rest all linked to news about the footbalclub. Google trends has not (yet?) the capability of building in some intelligence in the search terms. It's fun altough to play with.

AFP Trouble after 10.4.6 update

Scenario: you have a Mac OS X server spinning happily and you notice that there is a 10.4.6 upgrade. You also have 15 minutes to spare so why not upgrade right now™

A reboot later you find that your server is doing everything fine. Everything except AFP. Great update right?

A quick visit to the Apple forum learns you that you are not alone ™

Solutions like the one @ Apple discussions are, to my taste, a bit vague. Why fiddle around with shares, move files around and do other voodoo to your otherwise fine working server?

When a customer of ours called we could quickly help him, just replace /usr/sbin/AppleFileServer with an older version. The one which comes with 10.4.5 works fine. If you forgot to make a backup of your server you can a copy here.

mv your existing /usr/sbin/AppleFileServer to /usr/sbin/AppleFileServer.funky and move this copy in its place. You should be able to restart the AFP service without problems now. IF you don't want to mess around with your server just run the AppleFileServer binary from any other location.

Note: this is only a quick fix, but at least you have your AFP shares back without too much hassle and it buys the time we need to wait for a real fix from Apple.

Anyone with knowledge on the /.vol directory might be closer in understanding what is going on, when AFP inits it apeears to die on stuff in that directory:

   887 AppleFileServer CALL  getattrlist(0xf007cc20,0xf007d470,0xf007d0b0,0x3a8,0x5)
   887 AppleFileServer NAMI  "/.vol/234881032/274098"
   887 AppleFileServer RET   getattrlist 0
   887 AppleFileServer PSIG  SIGBUS SIG_DFL
   887 AppleFileServer RET   waitevent -1 errno 4 Interrupted system call

De-google-ify: how to protect your privacy when using Google

Google is hot in the netherlands. It's mostly coming down to privacy. So besides absorbing the unilateral news I searched for information on my own computer.

What is Google doing on my computer? How deep are they digging into my system? So I opened Firefox. A favorite browser of mine because of it's privacy protection. The way to collect user-specific information (amongst others) is by using HTTP cookies. So I started looking for the Google cookie.


My step-by-step plan:
1. Starting up Firefox, delete all cookies (Firefox > Preferences... > Privacy > Cookies > Clear all Cookies).
2. I quit the application (after checking that all cookies were deleted).
3. Started it up with an blank homepage.
4. Checked the cookies and there it was. Only one cookie! From Google. Without surfing, without visiting a site.

What could be responsible for placing that cookie there?
In the right top of the browserwindow there is a Google search option. It's default installed! Not when I surf to a site. No without my knowledge the cookie is there all the time.

My solution for the time being, at least untill I find out more about my privacy protection:
1. Start up Firefox, delete all cookies (Firefox > Preferences... > Privacy > Cookies.
2. Click button 'Exceptions'.

3. Add in field 'Address of website' the IP number of the Google homepage 66.249.93.99. Add google.com, google.nl or others.

ATTENTION: Google owns the NetRange 66.249.64.0 through 66.249.95.255. So it's not watertight, they can't all be blocked. But it was fun to watch the result. No cookies from Google on my computer. At least for now...

Besides the cookies I think there's another matter of attention. They provide so many services that even using a few of them can give them the opportunity to collect information about me. The treath is in connecting all that data together. But that's a comprehensive threath. When connecting my digital shoppingbonuspoints to my digital medical file someone can find out about my habits. Because I buy so many fat food my changes for a heartattack a severe. That's why my healthinsurancecompany is raising my contributions...
