Hackintosh

It seems like, the if not even more rogue "group of hackintosh" might hit a stumbling block:

http://osxdaily.com/2009/10/31/hackintosh-netbook-users-take-note-snow-leopard-10-6-2-update-kills-support-for-atom-processor/

which let me make something clear - QUIT SHOOTING YOURSELF IN THE FOOT APPLE!

I mean do we all really have to pay for your overpriced laptops with sub-par parts. What is so hard about being a bit more like linux? Why not extend a development branch to arm/mips-el/amd - kernel drives and kernel building kit would be a appreciated. Why not have broader hardware support like the BSD's/Linux? ffs make a modular Kernel with autodetect and activate driver support! your a multi million if not billion company - challenge yourself!

-Dont charge 1800$ for a 30" monitor thats CRAP! they are much cheaper online for the same or better parts.
-Dont charge 900$ for a 24" monitor - where I have found one for 250$ that is comparable if not better.

ARE YOU FUCKING KIDDING ME IM PAYING ALMOST 3x more for a stupid logo?? REALLY?! Your no better then micro-shaft with there bloatware OS! Im mean really what would hurt if you took a page from some of the Community maintained OS's out there?

- Better support
- More Architectures
- More Driver choices
- Reasonable if not competitive with retail prices
- Commission based OS application development

I once heard a Microsoft sales guy say something very,very true as much as I hated hearing it, it had a ring of truth:

"You meet many pure Linux and Windows developers, but when was the last time you ever met a pure Mac developer?"

In truth I've never met a "Mac only developer" in fact i've met very few Linux developers that will even touch MAC's and the few that do develop there software for MAC's none of them do any such "Hardware/firmware" level development.

I can see it your way though too -a high level of "working" products with "quality" but what makes you any better or different from Microsoft. I have yet to see a difference.

MIT Open Courseware

Apparently "open" course guidelines and such for structured classes from MIT and a few other one off online schools.

http://www.onlinecourses.org/2009/10/28/100-incredible-open-courses-for-the-ultimate-tech-geek/

So far i've actually worked through the beginners Python class. Its not bad.

[ Linux ] x_hk.sh

This script came via the neccesity to abolish services that would result in a reboot/cpanel/panels that inject restart commands onto vps's. As you see it could run alot everyday if something was making it run every 5 minutes like scron.

[ Centos ] Postfix dsn status script

Centos postfix DSN translation script - tells you what your mail is doing. In case you have no clue what we are chatting about view your maillog/mail.log :

Oct 1 00:35:01 ghosting postfix/smtp[1437]: ABA987666094: to=, relay=gmail-smtp-in.l.google.com[209.85.222.73]:25, delay=9881, delays=9880/0.01/0.22/0.71, dsn=2.0.0, status=sent (250 2.0.0 OK 1254342900 5si70217753pzk.88)

This largely tells you what has been done with your mail when the "status=xxxxxx" line or the message of why your mail fails is "vague".

FreeBSD - Ncurses menu config location

So something cool -

In FreeBSD when you install a port and encounter a ncurses ui and then hit ok, where does it go?

/var/db/posts/$portname/option

check it out some time :D

FreeBSD - Installing postfix & sending your first mail

Postfix: Probably the premier replacement for sendmail, which comes with ux/linux.

$> cd /usr/ports/mail/postfix-current/
$> make install clean

At this point you will most likely be confronted by a ncurses menu. You can choose to enable options or not. We just want to go with stock options so tab to ok and hit enter. So this should just go on and do its marry thing. If you get any other boxes just stick with defaults and tab to ok, and install.

Now to test!

telnet to your local host on port 25, and then type the following:
$> telnet localhost 25

ehlo example.com

*After this you should get accouple messages that start with 250 - this is good!*

mail from: root@example.com

*another 250 message*

rcpt to: type_your_email_address_here_instead_of_this

*another 250 message*

data

*another message*

subject: This is a test message!!!
test message
.

*message about being queued*

quit

* This will exit telnet, and we will sleep the following command for a minute to check your mail log to see if its been sent *
$> sleep 60 && tail /var/log/maillog | grep sent

if it comes back with sent your gold and you've sent your first message.

**** Just a side note, this is how it works in linux - infact i had to configure linux more then bsd

Please respond if you have issues :)

FreeBSD - Adding/setting up Grub

So your from linux land or you just want to try something new... Try grub :)

Lets located grub:
#> whereis grub
/usr/ports/sysutils/grub

Move to grubs port directory and install it:
#> cd /usr/ports/sysutils/grub
#> make install clean

Make the Mbr writeable, which is needed for grub:
#> sysctl kern.geom.debugflags=16

Now for the fun part! Installing - if you have a basic install this work just fine
#> grub-install hd0
Entering the grub subsystem:
#> grub
grub> root (hd0,0,a)
grub> setup --stage2=/boot/grub/stage2 --prefix=/boot/grub (hd0)
grub> quit

Making a menu.lst file that will take you to a free bsd booter.
#> nano /boot/grub/menu.lst

title FreeBSD 7.2
root (hd0,0,a)
kernel /boot/loader

Reboot the box and cross your fingers ;)
#>reboot

So I hope this worked for you, it worked great on my VM machine, and a few other boxes i've installed.

FreeBSD - Adding/setting console to Bash

Mind you after the fresh install you will probably have to do this as your root user until you install su or sudo.

$ echo $SHELL
/bin/csh
$ cd /usr/ports/bash3/
$ make install clean
~ This will download extra components && files ~
$ chsh -s bash root
$ chsh -s bash $USER
$ exit

~ Relogin and verify ~

# echo $SHELL
/usr/local/bin/bash

^_^ you now have bash shell!
