The one problem with that (it's beautiful) is at :00 it thinks the next one is :00

When it should be :30

htorque

nah, you'll never hit it at the exact millisecond :P

Oli

Hmm. Now it's 1 past and it's still saying :00

Stefano Palazzo

did someone say import this? :)

Oli

No... Actually, it's 23:02 and it's saying the next one is 00:00

Stefano Palazzo

my mess seems to work okay at midnight

@StefanoPalazzo that list sounds like a party pooper :D

Stefano Palazzo

yeah, they contradict each other too

Beautiful is better than ugly.
Explicit is better than implicit.

I first noticed when I wrote this:

lrot = lambda x, n: (x << n) | (x >> (32 - n))

htorque

| was bitwise or?

Stefano Palazzo

yes

htorque

it's definitely too late for me :D

Stefano Palazzo

I don't think anybody's supposed to understand why that works, but it is beautiful

Ok, I know you have all already been a great help with this effort today (mainly @StefanoPalazzo). so Thankyou :)

Q: Why am I getting btx halted trying to install FreeBSD?

When trying to install FreeBSD 8 off a USB Drive (UNetBootin loaded) I receive BTX Halted when choosing any of the Boot options. Here is my system I have 256meg of ram on it, and a Transcend CF 133x 4GB for its drive. I searched the FreeBSD supported hardware and It says AMD Geode LX is...

@JorgeCastro put the requests there: meta.askubuntu.com/questions/1177/…

Stefano Palazzo

68 followers on the freebsd tag, looks promising

wisemonkey

@rlemon: r u trying to install in VM or on HDD partition

rlemon

I'm trying to first boot from the usb drive

btx is the freebsd bootloader

when booting off the usb drive I get a few options (safe mode, default, single user, ect)

wisemonkey

hmm so is it like live freeBSD USB drive?

htorque

11:10 PM

good night all

Stefano Palazzo

bye htorque

wisemonkey

night

rlemon

you familiar with UNetBootin

wisemonkey

yea not as much as startup disk creator though

but as u said u have .img file it maybe possible to write only through UnetBooting right?

rlemon

well UNetBootin has an option for FreeBSD 8 / looks like it's their net install bootloader

wisemonkey

11:13 PM

ohh ok

rlemon

I have tried dd the img but that didn't work.. to be honest the UNetBootin got me much further than anything else.

wisemonkey

some good music to follow good work... dont get distracted! youtube.com/watch?feature=player_embedded&v=HQWkJyjwvnU#!

wisemonkey

this one says u need to use PIO or Simple DMA rather than ultraDMA if u have it in BIOS

rlemon

damn, how did i not see that one. I read like 15 people reporting this problem.. all with different solutions.. none worked for me.

i will have to try that tomorrow when i get to work.

btw this is the screen..

Yes, many have ran into this. The cause is a lack of emulation of certain i386 "real mode" instructions by FreeBSD, which runs in "i386 protected mode". IIRC this should have been fixed in 7.2 -- somebody commented

rlemon

1-5 result in the BTX Halted error

yea I also read that.

most were due to hardware incompatibility

Stefano Palazzo

does unetbootin offer an image for NetBSD?

wisemonkey

haha I don't think 6-7 are much helpful

rlemon

@StefanoPalazzo yes!

Stefano Palazzo

("of course it runs netbsd")

well netbsd will run on a 19th century steam engine, you should give it a try

rlemon

11:18 PM

I don't think the problem is my hardware being too old...

:P

Stefano Palazzo

right, but your hardware is a little bit odd, right?

I don't know much about the Geode, so I could be wrong

rlemon

not really.

Oli

The geode is x86 IIRC... just a bit slow.

rlemon

Geode (processor)

: For other uses of Geode, see Geode (disambiguation) Geode is a series of x86-compatible system-on-a-chip microprocessors and I/O companions produced by AMD, targeted at the embedded computing market. The series was originally launched by National Semiconductor as the Geode family in 1999. The original Geode processor core itself is derived from the Cyrix MediaGX platform, which was acquired in National's merger with Cyrix in 1997. AMD bought the Geode business from National in August 2003 to augment its existing line of embedded x86 processor products. AMD expanded the Geode series t...

and of course it does run netBSD

it's only x86-32, is it?

rlemon

and i'm porting from QNX 4 - so there isn't really much the OS needs to offer right now..

@StefanoPalazzo yes

Stefano Palazzo

...and unetbootin didn't download the amd64 image

rlemon

made sure of it.

Stefano Palazzo

I thought so.

rlemon

freeBSD 8
freeBSD 8x64

two options.

Stefano Palazzo

11:23 PM

wow, you can get these for 100 euros here

(plus a PoE switch, or a power adaptor for 7 euros)

rlemon

yea they're not that expensive. we pay a couple hundred for them

we really need maybe 20% of it's capabilities.. however our old manufacturer went bellyside so we recently had to switch. our core product is basically 20 years old. most major updates have been due to hardware no longer being available to buy.

Stefano Palazzo

what do you use them for?

rlemon

automation control for industrial dryers (grain, corn, petfood, ect..)

it's a low to no tech industry.. so we kinda capitalize the market.

:)

Stefano Palazzo

nice :)

rlemon

it's just hard to get people on board with some of this stuff.

wisemonkey

11:30 PM

sounds fun to me :)

rlemon

recently went to china.. people there still dry wheat on an open field in the sun with shovels... just keep spreading and turning...

thats big companies.

try explaining networking to a farmer. :P fun times fun times.

wisemonkey

hehe

rlemon

anyways. @wisemonkey have you ever used bsd?

Stefano Palazzo

I've got to buy one now. :\ I can get excited about embedded controlling system, easily

rlemon

@StefanoPalazzo ohh they are fun to play with.. put linux on it and have fun, I'm buying one to build my own HAL

wisemonkey

11:34 PM

I installed once but thats all I'm not much fan of bad/no UI thought I work in embedded/hardware industry :P

though*

Stefano Palazzo

@rlemon how do you go about making it do stuff?

let me phrase that better

what kind of hardware do you use to make it flip switches, and so on?

rlemon

lol, that you also have to build.

in highschool i did a concept "smart house"

wisemonkey

hmm I/O interface and flipping switches -- relays

rlemon

had a cough VB cough application tied into some webcams

wisemonkey

lol I've worked on 2 smart switches ;)

Stefano Palazzo

11:36 PM

I've looked at some of these USB measuring and regulating interfaces, they're quite expensive and very proprietary

rlemon

@wisemonkey basically - yes that was what i did.

wisemonkey

@rlemon yey :D ok then I'll say mine were smarter than ur :P

haha jk

and @StefanoPalazzo u find wide range of them

rlemon

probably. i was 15

wisemonkey

umm u r younger to me I give u that :)

Stefano Palazzo

rlemon

11:38 PM

i'm 25 now. had a great highschool engineering teacher. taught us the local universities 5 year program in 4 years in highschool. (because he taught it there and thought it was too easy)

Stefano Palazzo

this is what i had in mind. it's basically 2 D/A converters, 8 A/D converters (150€)

rlemon

skipped on some theory, but covered the gist of it.

wisemonkey

@StefanoPalazzo: if u r willing to put more efforts then u can get most rudimentary component do same thing as most expensive, here the example I worked on project which had like twice the features compared to competition

while competition was selling it for 300$ we could sell it for 120 with 60$ profit :P

rlemon

anyways. gotta grab some dinner. night all

wisemonkey

night

Stefano Palazzo

11:40 PM

bye rlemon

wisemonkey

lol yea tell me about skipping theory :P

Stefano Palazzo

I'll be off too.
