EDIT: I finally got around to rewriting this script, it is acually readable and more usable.
EDIT2: Emulated default scroll wheel item switching, and added view model aliases for ease of use.

alias view1 "slot1; r_drawviewmodel 1"
alias view2 "slot2; r_drawviewmodel 1"
alias view3 "slot3; r_drawviewmodel 1"

bind MWHEELUP "prevslot"
bind MWHEELDOWN "nextslot"

bind q "lastslot"

bind 1 @slot1
bind 2 @slot2
bind 3 @slot3

alias push0 ""
alias push1 ""

alias @slot1 "view1; push0; push1; alias push0 stack1; alias nextslot @slot2; alias prevslot @slot3"
alias @slot2 "view2; push0; push1; alias push0 stack2; alias nextslot @slot3; alias prevslot @slot1"
alias @slot3 "view3; push0; push1; alias push0 stack3; alias nextslot @slot1; alias prevslot @slot2"

alias stack1 "alias push1 pop1"
alias stack2 "alias push1 pop2" 
alias stack3 "alias push1 pop3" 

alias pop1 "alias lastslot @slot1"
alias pop2 "alias lastslot @slot2"
alias pop3 "alias lastslot @slot3"

OLD POST:

So I have had a minor annoyance with scriping in TF2, namely there is no way to do weapon based setting in all cases, like when using the lastinv command. While this can be worked around, if you want to do +- weapon binds, you are forced to use lastinv. I just recently came upon the solution to that problem, a implementation of lastinv, done competely in aliases.
All credit goes to MrRadicalEd of the Natural Selection forum.

//to use, use "lastslot" where you would otherwise use "lastinv", and @slot# where you would otherwise use slot#

Well?

You don't need a aftermarket CPU cooler(-$32), the boxed intel cooler will do fine if you don't overclock much. Put that toward a better GPU, like a 760 http://ca.pcpartpicker.com/part/asus-video-card-gtx760dc2oc2gd5(+$30)

You can also cut costs by getting a cheap case, or reusing your current one. http://ca.pcpartpicker.com/part/cooler-master-case-rc361kkn1 again, unless you are overclocking, you dont need massive airflow.(-$120)

Go with win7 over win8.(same price for a better os)(-$0)

For storage, get a 1TB 7200RPM and a 32GB SSD. (-$100)

Boom, $100+ saved

Sorry for the necro, bur if you find this via google like me, twitch reccomends irc.twitch.tv over USERNAME.jtvirc.com, as the latter has been wonky recenty.

Are you running on the admin account or a non privileged account? Try clicking the "show processes from all users" button first.

Can you post a process dump?

Happy B-day you glorious bastard!

The popping was from capacitors exploding. If they are on the Mobo then you need to get a new computer. If they're in the PSU you can replace just that.

currenty, changing interp in the fly seems to crash servers.

To my understanding, vpk's don't need to be defragged like gcf's did. Gcf's were big, cluncky, and un-updateable. They were essentally a container file with the same directory as /username/gamename/. Vpk's are smaller, and strip all the file header info of all the internal files to the header of the vpk, along with crc data, file size and bit offset within the vpk. This along with /custom/ allows for less file calls and generally faster load times.
