so i managed to update freebsd from 6.2-RELEASE to 7.0-CURRENT by religiously following the handbook without any hitch. this thanks to the quality of the documentation. however, i still prefer gentoo's handbook, which is more intuitive, easy to navigate, understand and follow.
well, all i'm trying to say is, if you're planning to go freebsd-BLEEDINGEDGE, follow the instructions in the handbook first.
A few reasons why i'm not getting the iphone, yet
- No HSDPA or even 3G support. I mean, dude, yeah there's wifi but using wifi with your iphone on public wifi network? And EDGE? That's like, neolithic man
- No Java and Flash support in the browser. That eliminates half of the world's website oledi...
- No games! See, I spent an hour each day in the toilet playing collapse and alien invaders. My scores for both games are at 999,146, just a few hundred shy of 999,999. That tells how much I need them games. In the toilet. Crapping
- No GPS. I get lost pretty easily. Especially when talking to girls. So I desperately need them GPS to guide me. Really.
- No quick shortcut to make calls. Liek, I wanna liek, yanno, call takizo and talk about shit and stuff, yanno, in liek, 2 key taps, or 1 if possibal, as opposed to liek, yanno, tapping yakkittyyakkityak so many times, yanno, it's liek, uncool, yanno

the dell 2007wfp 20 inch ultra sharp wide screen lcd monitor is pretty cool. for the past three days my macbook is running in clamshell mode, with no side effects. doing this is pretty easy. first you gotta have the mini-dvi to vga cable (duh!). then turn on mirroring (press F7). os x will automagically detect the monitor and adjusts the resolution accordingly. the highest resolution for this monitor is 1680 x 1050 @ 60 hz - i am not sure if you can get higher than this with macbook pro - i only have macbook. after connecting the monitor, keyboard and mouse, close the lid, and the macbook will go to sleep. the screen will blank. wait approximately 10 seconds, then tap on the keyboard and voila, the macbook will wake up and you're set. you can open the lid and confirm that your macbook monitor is off. the clamshell mode works on with and without the power adapter.
temperature wise, i notice an increase of between 5 - 7 degrees, thus the obvious thing to do is to open the lid of the macbook once in a while to lower the temperature.
the following are visualization of a four-minute packet capture of DDoS attack on a webserver. traffic was captured using tcpdump, and anonymized using tcpdpriv. (this packet capture was given to me by a friend)
this is a graph of the attack using afterglow. you can hardly see the IP addresses and there were too many of them - this is not a limitation of afterglow, but rather a limitation of 2-D visualization. a 3-D image would better to show the severity of the DDoS attack.
source and destination bytes, graphed using ragraph
the average bytes is roughly 7 Mb per second, which can be roughly translated to 40Mb per minute, which is quite a lot of traffic. these are mostly UDP traffic with huge payload.

at work, microsoft outlook is the main tool. my everyday job consists of reading, composing, and following-up on emails. a single task can span multiple threads, days, and sometimes week, within multiple receipients and senders from at least three different timezones. my emails communication consists of mostly three subjects: tasks assignments, status updates and information inquiries. emails are usually replied one day later (due to timezone differences). in order to keep track of things, i use a simple method to keep things organized (something i read about email gtd in the web). i have four folders: Inbox, Archive, Follow-Up and Todo.
Inbox is where all my incoming mails go to. I don't use any email filters. From here, the emails will go to either Archive, Follow-Up and Todo folders. And my Inbox is always empty.
Archive is for emails for tasks that have been completed, replies to queries, general information, HR newsletters. In short, it is for emails that I don't have to take action.
Follow-up is for emails that I need to follow-up later, tomorrow, or next week. Examples are emails that say a certain task will be completed next week, or some information will only be available after mr blabla comes back from vacation, etc etc.
Todo is for emails that I need to act-on. Basically, Todo is my own list of tasks to, well, do.
I could have used my Inbox as a todo list, but that is confusing and most of the time, I don't get on act on the items in Todo folder after I've done something else. I like to think of the Inbox as a transit point.
This method have worked effectively for me since I've large amount of emails everyday. On top of this, I don't
- use any email filters
- group emails based on subject or threads
This makes it easier to sort the emails into Archive, Follow-up and Todo folders.
