That's very interresting. The site sais:
Dash includes maps for the United States (Continental US, Hawaii and 
Alaska) only. It will not work in Canada, Mexico, Europe or any 
location outside the United States.
Since when are Canada, Mexico and Europe in the United States? I 
thought I would live far away from the USA (Germany). ;-)


equaly weird when you have a flight from Europe (Germany) to Canada 
(Vancouver) and you have to change planes in Chicago. Canada is listed 
as a national departure not international... So I have get off the 
international arrivals and get through the customs to check in to US??? 
my globe recently said Canada and US were two different nations ;-)


anyway back to Topic.

the Dash is really an impressive gadget. Id like to have one or at least 
see some process in implementing routing with openstreetmap vector data.

May I make a suggestion to whoever is running this mailing list to add
the greylist technique to it as well?  I have had milter-greylist 
running on

my main email servers for over 12 months now, and the amount of spam
reaching my users/mailing lists has gone down to almost zero.
  

I know greylisting works and is stopping spam very effective (for now).

However this behaviour puts high volume mailservers in a lot of stress. 
Also I am experiencing, that spammers are adapting to greylisting and 
are connecting multiple times to mailservers. Supposedly in order to 
pass greylisting.
Thus, the administrators of these high volume mailservers  have to get 
rid of several thousands incoming connections per minute from a single 
spammer (think of a botnet DDoS you) and delayed outgoing connections 
for your customers.
You therefore have a higher deferr rate outgoing  (doubling outgoing 
connections) and therefore have a bigger mailqueue, additionally you 
have more incoming connections (spam) blocking your available TCP ports 
permanently only for the cause to reject them.


So my advice would be to not use greylisting, as it pushes the problem 
to other parts of the internet and is effective only for a limited time 
(if anyone is using it).


My thought is, that it would be much more effective to block 
subscription by sophisticated captchas (take care of XSS vulnerabilities 
) . Also it might be effective to block subscriptions by using lists of 
compromised hosts like CBL (http://cbl.abuseat.org).
Try to identify which IPs are causing trouble and do match them with 
several blacklists. The lists do not always work in the same way as it 
does for others. Sometimes also only a mix of several lists are working. 
http://karmasphere.com/ might help you there.


If you dont have enough samples, be conservative. It is more a hassle to 
gain legitimate listmembers back, who you have been lost during 
subscription, as blocking fake accounts afterwards.


Have an eye on your subscriptions. Too many new listmembers is certainly 
not a cause of marketing.


I might have come a little off topic, but perhaps it helps someone.

I am now getting back to my cookies, ice cream, cake and teas ;-)

Cheers Thomas

interesting stuff

this has got me thinking - openstreetmap is progressing as a nice
alternative to google maps and so on, but is there an open-source
equivalent for the photography part of google maps/earth? something
working in a similar way to osm, using photos taken by anybody, with a
UAV or any airborne vehicle, and licensed under GNU FDL? this sort of
technology is getting cheaper and cheaper, it's well within the price
range of common people now

UI-wise this could be realized in organizing the addressbook more like a
IM client where you can see if your buddies are in BT-/WiFi-Range,
Online (via any network connection (GPRS/UMTS/BT/WiFi)) or offline
(callable/SMSable). In any situation you could choose to send text/chat
or call your buddy. And the phone chooses the best (cost/battery
life/reception) way to contact the buddy.

what do you think?

How about friends list? so you can basically add people to your 
friends list via email.


The Nintendo Wii has a serial number built in and you can send a 
friend request to another Wii or to any other email address. When 
sending a message for the first time it asks for permission to be 
added (one way to stop spam).


You can then email pictures to your Wii.

An easy way to install new software would be to be able to email it to 
your phone and use the phone's wifi to download the email. Of course 
security would have to be present to stop it installing anything 
received in an email.





Hi,

correct me if I am wrong, but shouldnt Jabber/XMPP do this out of the 
box with (formerly Apples) Bonjour 
(http://www.xmpp.org/extensions/xep-0174.html)?


You should simply have your IM Client active and see automatically every 
friend who is on your list as available (or what message he has 
selected). Exchanging data like pictures, binary or simply text is 
therefore already implemented?


For seeing people how you dont know, you could join a Chatroom called 
Local for everyone available in short range technoligy like 
Wifi/BT/Infrared and Global for GPRS/Wifi(Internet). Who is subscribed 
to your personal Global Chatroom should be identified first... probably 
some kind of social group which has met before in person... 

Managing your calls over Jabber should also be possible through a IM 
Gateway which communitcates to your phonebook. Click on a friend and 
open a jingle connection directly (wifi/bt) to your friend or first to 
the gsm module which then dials out over normal voice


Regards,

Thomas
