Excerpt

8 symptoms of groupthink from Little Book of Behavioural Investing
1. An illusion of invulnerability - This creates excessive optimism that encourages taking extreme risks.
2. Collective rationalization - Members of group discount warnings and do not reconsider their assumptions.
3. Belief in inherent morality - Members believe in the rightness of their cause and therefore ignore the ethical or moral consequences of their decisions.
4. Stereotyped views of out-groups - Negative views of "enemy" make effective responses to conflict seem unnecessary.
5. Direct pressure on dissenters - Members are under pressure not to express arguments against the group's views.
6. Self censorship - Doubts and deviations from the perceived group consensus are not expressed.
7. Illusion of unanimity - The majority view and judgements are assumed to be unanimous.
8. "Mind guards" are appointed . Members protect the group and their leader from information that is problematic or contradictory to the group's cohesiveness, view and/or decisions.

HTC Legend USB tethering with Linux

HTC Legend USB tethering works out of the box with Linux, nothing else was required which was pretty cool.

However, when I re-enabled my original eth0 connection (which was statically configured), my browser failed to resolve any of the URLs. It turned out that the dns server in my /etc/resolv.conf file was replaced by a reference to the Legend's IP address.

Ok, will try out USB tethering with OS X 10.6 when I get home. Hopefully, it will work out of the box else maybe something like usbnet will help.

Hackintosh

This post is going be about my experience of installing Kalyway's Hackintosh 10.5.2 Leopard on my Dell Latitude D610 laptop. The experience was relatively smooth sailing except for the part when I wasted 3 DVD-R burning the iso file. It's just works after I started using a DVD-RW; don't know why though.

The trick is to keep clicking yes (rather idiot-proof) when prompted until the stage when the bootloader is to be installed. De select the bootloader for GUID and select the one for MBR instead. I think this is for OS X to know that it is booting of BIOS (MBR) and not EFI.

Check http://wiki.osx86project.org/wiki/index.php/Main_Page for references.

After OS X installation, I edited my menu.lst of my GRUB bootloader to triple boot my laptop, cool... Once inside OS X, I noticed that the OS was clone off a MacBook Pro and it thinks that my D610 was a MacBook Pro.

The ethernet was not working though I got a valid IP address. Upon further digging, I found that the ethernet's MAC address is 0.0.0.0.0.0; so even though it's got a valid IP, the packets sent to this IP will not be received by my MAC since it MAC address is invalid. This is probably because Apple hardwire the MAC address within some EEPROM inside the MacBook Pro that's missing in my Dell.

So far, I haven't found anything new that I really like inside Leopard so there's no real reason to upgrade from Tiger to Leopard (sorry Apple). After this exercise, I formatted the OS X drive and mounted it back to my /rubbish on my Linux. Overall, an interesting weekend project.
