This is some kind of open discussion with images and videos possible. The public waves are big and so the JavaScript seems to be some performance limitation. Public waves have been slow. tech http://www.tower-net.de:80/blog/2009/11/08/1257673320000.html#comments http://www.tower-net.de:80/blog/2009/11/08/1257673320000.html Sun, 08 Nov 2009 09:42:00 GMT http://www.tower-net.de:80/blog/2009/10/18/1255880220000.html At November 11th at 16:27 CET there is again the event <a href="http://www.langenachtderforschung.at/pstart.php?r=T">Long Night of Research</a> organized by universities and research institutes of Innsbruck.<br /> The program is available as <a href="http://www.langenachtderforschung.at/downloads/LNF09_PROGRAMMMAGAZINE_WEB/LNF09_PM_Innsbruck_Kern_WEB.pdf">PDF</a>. tech http://www.tower-net.de:80/blog/2009/10/18/1255880220000.html#comments http://www.tower-net.de:80/blog/2009/10/18/1255880220000.html Sun, 18 Oct 2009 15:37:00 GMT http://www.tower-net.de:80/blog/2009/10/18/1255876860000.html It will have been a year ago that I've visited the Austrian government portal for citizen services.<br /> With the social card (e-card) each Austrian has the possibility to use this card as digital signature card. With the card and a card reader for your computer (something I don't have) you could use online services to communicate with&nbsp;governmental authorities.<br /> The alternative is to visit offices in person or mail via postal carrier.<br /> So it would be quite a nice, comfortable way.<br /> Yes, but for the SSL certificates used on the secured websites it is difficult for the citizen to trust...<p><a href="http://www.tower-net.de:80/blog/2009/10/18/1255876860000.html">Read more...</a></p> tech http://www.tower-net.de:80/blog/2009/10/18/1255876860000.html#comments http://www.tower-net.de:80/blog/2009/10/18/1255876860000.html Sun, 18 Oct 2009 14:41:00 GMT http://www.tower-net.de:80/blog/2009/10/18/1255819020000.html The harddisk encryption is only defense against simple theft.<br /> A spy can install a tool on Alice's unattended computer and get to know the password for her encrypted disk.<br /> Afterwards the spy Bob knows the password and can boot Alice's computer with its encrypted harddisk or can copy all the unencrypted disk data.<br /> The so called &quot;<a href="http://theinvisiblethings.blogspot.com/2009/10/evil-maid-goes-after-truecrypt.html">Evil Maid Attack</a>&quot; by Joanna Rutkowska replaces the boot code on disk to sniff Alice's password and continues with boot afterwards.<br /> If the boot is protected by BIOS, Bob has to connect the encrypted disk to an own computer to install the tool.<br /> If the encryption is hardware based there might be possibilities to hack the BIOS for a password sniffer. But this kind of encryption is much safer because Bob has to know a lot specifics about Alice's computer. Bob might run out of time doing his work without getting nabbed by Alice.<br /> Mmh. I've to check the laptop of our team. I'm interested in how safe its encryption is ;-) tech http://www.tower-net.de:80/blog/2009/10/18/1255819020000.html#comments http://www.tower-net.de:80/blog/2009/10/18/1255819020000.html Sat, 17 Oct 2009 22:37:00 GMT
