@rawbrawb I just posted an excellent answer to an old question, and I am going to promote the crap out of it here. You are my first target!

@rawbrawb Are you sitting down?

A: Cheapest way to add wifi to a project

Cheapest way to add WiFi to a project, is to use a WiFi router. The router needs to be not-so-new in order to be cheap, and must supports Serial OpenWRT or JTAG See OpenWRT supported hardware page for information on what hardware is supported. Since OpenWRT is.. you know.. open, you can get t...

rawbrawb

@angelatlarge that's a good way to do it. the OP isn't clear if he needs a board solution, so it might be OK. nice tangential thinking.

angelatlarge

@rawbrawb I am a cheap bastard, and that's what I started to do. Never got around to finishing, but I think that is the absolute cheapest you can do WiFi. Lots of work, but kinda fun.

@rawbrawb Thanks for the love

good morning

@angelatlarge but do you still have the blinking LED?

angelatlarge

@jippie Yeah.

@jippie But now it is being handled at the mothership :)

@jippie Good morning.

I sense a moderator being around :)

I am now Enforcer -15 :)

Time to get another beer from @jippie's country.

jippie

?

are you drunk?

angelatlarge

@jippie Not yet, but working on it.

@jippie I see you are beer huntin' yourself, sir.

jippie

at least you practised compiling avr-gcc

angelatlarge

@jippie Geez! Do you know how long it took?!?! It took like... 3 hours to have gcc compile gcc.

jippie

06:02

there are tools to parallelize compiles over multiple computers on the network. I used to do that all the time when I was using Gentoo.

angelatlarge

@jippie Parallelize compiling of compilers? I don't have six identical laptops here, you know :)

jippie

You should try compiling KDE, speaking about long compile times

they don't need to be identical

angelatlarge

@jippie Call me "drunk", but I think I'll pass.

jippie

as long as they have similar compilers :-p

angelatlarge

@jippie Well, compiling gcc is very configuration specific, I thought.

jippie

06:04

mwah

..

angelatlarge

@jippie Who's drunk now?

jippie

actually it is too long ago to be absolutely sure if every package could be distributed

whatever

angelatlarge

@jippie Anyway, your freebeer points on SE are in jeopardy, I am afraid :(

@jippie Did you see my rocking wifi answer, BTW?

I think it is so damn awesome I've been spamming everyone on chat with it :)

@jippie Looks like you are my next victim...

angelatlarge

06:38

@jippie Looks like we have progress on the LED.

sourceware.org/bugzilla/show_bug.cgi?id=13697

jippie

@angelatlarge so it is in the data files used by the compiler?

angelatlarge

@jippie oh, crap it is fixed in an unrealeased version of binutils. But I guess I can just get rid of the switch.

@jippie You responded to the wrong thing, I think

@jippie It's in binutils, in this case in ld (the linker)

@jippie Indeed a compiler bug :)

@jippie Or, more precisely, a linker bug. But actually, I don't understand why linux should be fine: the fix is in 2.24, which isn't out.... Weird.

Need to check binutils version... on my Ubuntu machine which does build correctly.

jippie

@angelatlarge because Linux users don't have to compile their tool chain themselves every time :-p

angelatlarge

@jippie Rather than being an explanation, that's an ad hominem attack.

jippie

?

angelatlarge

06:48

Ad hominem

An ad hominem (Latin for "to the man" or "to the person"), short for argumentum ad hominem, is an argument made personally against an opponent instead of against their argument. Ad hominem reasoning is normally described as an informal fallacy, more precisely an irrelevance. Types Ad hominem In Latin, the word homō (of which hominem is the accusative case) has the gender-neutral meaning of "a human being", "a person" (unlike some of the words in Romance languages it gave rise to, such as French homme and Italian uomo). A translation of ad hominem that preserves this gender-neutralit...

@jippie Oh, now I understand your misunderstanding.

@jippie binutils is not used (just) in building gcc itself. It is used in building your avr binaries: gcc calls various programs in binutils.

@jippie That's where the error is, if I understand it correctly.

@jippie so ld (which is called by gcc to link, I believe) is part of binutils.

@jippie So to my thinking, if the bug is in binutils with using -Wl,--gc-sections parameter, then it should be present until Linux too

jippie

binutils 2.22.90.20120924 amd64 GNU assembler, linker and binary utilities

angelatlarge

@jippie Yeah, exactly.

@jippie So that isn't the full story, somehow. I am pretty sure my gcc params are identical on both systems.

jippie

probably the bug fix is backported to 2.22 too

hence the 20120924

2012-09-24

angelatlarge

@jippie Ah! That would explain it!

@jippie Nice.

Yeap, same here: GNU ld (GNU Binutils for Ubuntu) 2.22.90.20120924

I have a Raspberry Pi, and I want this to be a user interface to a PLC.

It will run the program I am going to write which will show the values that are sent by the PLC.

Also, it will send set values to PLC.

Maybe something like this, but much simpler:

@jippie Do you think Python with GTK meet my needs?

Caught up with a mate I hadn't seen for a while and he brought around a little project he'd been working on. First time I've actually seen an Arduino.

Stacey Anne

I'm trying my hand at manually making timing diagrams, do you think this looks OK? imgur.com/xN4hnid

PeterJ

12:21

@StaceyAnne, your clock rise and fall times look too slow ;-)

Stacey Anne

12:34

yea, i really must deal with that huge capacitance on the lines

:p

in all seriousness, I was thinking about using | symbols instead, but those didn't come out as nicely as the / \

PeterJ

@StaceyAnne yeah you would end up with a gap. Actually the only thing I thought looked a bit confusing were the 'X' inputs and outputs versus the clock. Maybe a few spaces so it's clear when the data is clocked in/out?

Stacey Anne

You mean like X X X instead of XXX

So that the X matches with the clock edge

PeterJ

Yeah, not sure how it would look though in practice

Stacey Anne

I'll give it a try now and we'll see

INPUT_CLK       _/¯\_/¯\__/¯\_/¯\_/¯\_ _ _ _/¯\_/¯\_/¯\_/¯\_/¯\_/¯\_/¯\_/¯\_/
INPUT_RST       ¯¯¯¯¯¯¯¯¯¯\__________________________________________________
INPUT_X         ______________/   X  _ _ _ _    X   X   X   \________________

it doesn't render so well in chat, lol

I'm stuck for what to put between the Xs though, a top and bottom bar in one char would be great, but I can't find one

PeterJ

13:00

Not sure either. Did you need to use ASCII chars? Not aware of any drawing packages that would let you do it quickly without a lot of tedious work but there might be something around that lets you add some of the basic blocks to a palette and has some sort of grid alignment so it's not too tedious.

user61389

Q: Software to create timing diagrams

In my professional life, I sometimes need to create timing diagrams for UART/SPI/etc protocols. However, I cant find any good programs available. Do any of you recommend any programs for this that you have tried and liked?

W5VO

@StaceyAnne You need to make it "fixed font" and then it will render fine

Stacey Anne

@W5VO, how did you do that?

W5VO

@StaceyAnne chat.stackexchange.com/faq#formatting

it's the ` character

Stacey Anne

@CamilStaps, I'm familiar with latex, but haven't gone through the learning curve of using it properly yet

@PeterJ, I was looking at only using ascii - or at an existing program I already use. I've just seen now that Openoffice Draw does timing, which might work quite well for me

user61389

13:59

@StaceyAnne neither have I, it isn't really needed for tikz-timing, you might try it if you're interested - here are examples

PeterJ

wow thanks @W5VO i++ ~~I love you~~

it works :)

abdullah kahraman

@PeterJ Tripod.

PeterJ

Kortuk

@PeterJ no, actually, we call him poplar. Like the thin wispy tree. He was nearly starved to death when we found him.

PeterJ

@Kortuk, it's sad to see people treat cats like that. In fact the kitten I'm talking about (Sooty) was rescued by my partner's daughter who works in a supermarket and saw they were locked in a car for ages. When she approached the driver she said she didn't want them and she could have them (she kept her brother).

@PeterJ holy crap. I would throw down. Our was just a wild cat that got bad luck.

Or I at least tell myself that as not to lose all faith in mankind.

@Kortuk One time I tasted a beautiful vintage 400V 150mA adjustable supply. It had a nice pop with a general mouth feel of lightly cooked meat and copper. The nose on the supply was an exotic warm dusty phenolic with hints of overheated carbon composition resistors. I would rate it 97/100

Nick Halden

@Kortuk Hah, I had the same problem a couple weks ago.

Kortuk

@NickHalden I was angry.

Nick Halden

@Kortuk So you whipped up an HDMI --> VGA converter real quick?

@NickHalden however, I did have a TV, which I waited until my wife was "afk" and stole the TV.

She was not amused to come back to linux booting up. I was promptly ejected.

@angelatlarge you are always allowed to reference your company if it adds to the question. You are also more then invited to answer questions well and have your company on your account page, so people can get more information when they want to, just dropping the name there is not so great.

@Kortuk I think references to corporations always look better/cleaner when they are not made by an entity associated with the company. If you are going to do such a thing, mentioning some competitors also takes away from the spaminess perception.

Kortuk

@angelatlarge Meh, I dont see an issue if it is directly helpful to the question. If you asked about proton therapy systems I would mention my company, it is my company, and I honestly believe we do it the best. In certain cases that would make sense.

@ThePhoton thanks. I don't think my diagrams will be more complicated than yours, I'm only doing some basic things like here on page 2 (unfinished document)

user61389

@ThePhoton I like tikz-timing because it's LaTeX

user61389

Heh, about that document: I wasted like 6 hours to get a MCP-like layout :)

The Photon

@CamilStaps I am a big LaTeX fan, but it has been years since I've been in a situation where I could use it.

user61389

16:36

@ThePhoton yeah, that is a problem - I'm now writing everything in LaTeX, just because it's fun (and I need practice), but it costs some time and energy (until I've learned more, of course)

rawbrawb

@CamilStaps have you used the timing extension? how well does it work?

The Photon

@CamilStaps I once wrote a characterization report that had like 30 pages of auto-generated graphs, all laid out in LaTeX with 6 graphs per page --- never could have done it in Word. But everything else in my working life I've had to do in Word because I'm not going to convince the rest of my company to learn LaTeX.

user61389

yeah, tikz-timing. It works very well! This diagram was made with

\begin{tikztimingtable}[timing/lslope=.5,timing/dslope=.5]
DT & 2D{}12D{}1D\\
CK & [H] 1H2{6T}2T\\
\end{tikztimingtable}

The package is quite customizable, also see the examples [here](http://www.texample.net/tikz/examples/more-tikz-timing-examples/)

rawbrawb

@ThePhoton I agree, I love the power of it. the big problem I have is that most journals that I submit to, don't take LaTeX!! But Word. totally backwards.

17:05

@JohanLarsson the comment about limit cycles NOT resonance is appropriate,

@JohanLarsson I was wondering why you have your recesses so long and narrow? i.e. do you notice the vibrations in one direction vs. the other? They are so different that you'd expect one mode to dominate over the other, which will be a big hint....

Johan Larsson

I don't really know what it means tbh. Does it mean that the vibration is due to control of the drive?

@rawbrawb it is legacy stuff, there is quite a lot of geometry in the supporting part. Not sure I can modify it much easily.

rawbrawb

@JohanLarsson resonance has to do with energy storage and "q" factor etc. wereas a limit cycle has to do wit the control meachanism, resolution "hunting" behaviour.

@jippie That's not correct for AVR development, actually. The variables are initialized to zero on AVR automatically, and if you do something like uint8_t myNum=0; the compiler will strip that out because it is a waste of both FLASH (the initialization values are stored in FLASH) and clock cycles.

@jippie BTW, the preceding applies to SRAM (=global) variables. I am not sure about local variables which are allocated a bit differently, though also in SRAM.

jippie

so should I upvote your anser?

angelatlarge

@jippie How could I possibly tell you to do that?

@jippie Completely up to you.

I was right about patching

angelatlarge

@jippie What I can say is that it has been tested. (non-zero) initialization aleviates the problem and changing the linker script does too.

jippie

only advised the wrong package

angelatlarge

@jippie I couldn't tell when the fix was actually applied and to what versions it was applied, or whether it was back-propagated though the old releases.

jippie

OK, I just decided that I'm going to set up half of my new desk (need to clean out the room for quite a bit), then I deserve a beer.

/me doing physical labour

angelatlarge

@jippie You haven't trained your cats to do your physical labor for you? They only get cheezburger after some heavy lifting.

jippie

love that site

angelatlarge

@jippie You are not supposed to admit that.

Kortuk

@jippie You, sir, always deserve a beer. Hell, let me drink to that!

angelatlarge

@Kortuk +1

rawbrawb

@Kortuk um Kortuk, you're at work ....

Kortuk

@rawbrawb SHHHHHHH

@rawbrawb I was told as a child, the moment you are a manager you are allowed to keep a bottle of nice scotch in your desk!

rawbrawb

18:07

@Kortuk THAT is a childhood!

Kortuk

(I never ever drink at work!)

Finally found it:

eberhardt.bz/GME_Wood_Land/GME_Woodworking_Stuff/4_Information/…

Unfortunately only goes down to a #0 screw, where an earlier rev of my design uses #000,

I thought I had the other half of the corner desk upstairs, now I can't put anything on top until the second part arrives

W5VO

@angelatlarge All I need to do to bump off the quote is to star 3 more "Star this message" lines :)

angelatlarge

@W5VO That's the problem. People star the metamessage intead of the message. WTF?

rawbrawb

@W5VO not really, we can do a redirect ...

Kortuk

@angelatlarge I starred yours so others would notice it :)

angelatlarge

@W5VO I am considering putting in "Power supply connosseur" with a link to that in my "about me" section.

Kortuk

18:50

@angelatlarge DOET!

W5VO

@rawbrawb I think it's just a chat link then

@Kortuk One time I tasted a beautiful vintage 400V 150mA adjustable supply. It had a nice pop with a general mouth feel of lightly cooked meat and copper. The nose on the supply was an exotic warm dusty phenolic with hints of overheated carbon composition resistors. I would rate it 97/100

jippie

@angelatlarge what's the message?

angelatlarge

@jippie It is right above yours :)

jippie

the message is "It is right above yours :)"?

rawbrawb

@W5VO Sucka!

you see what I did there? I got you to do the work!

W5VO

18:55

@rawbrawb now it's just a link

rawbrawb

@W5VO but it's still there! Bwahaha

W5VO

and now the original message is gone. This new one will be gone much faster now

rawbrawb

@ThePhoton Dats handy ...

jippie

I bet this is the first ever trappist being poured in a glass standing on top of an desk from my employer :)

rawbrawb

I've heard it said that @W5VO said this one time...

18:57

haha

rawbrawb

@jippie dude you're from the nederlands ... that's probably the first one THIS WEEK

jippie

I'm talking trappist, not lager

rawbrawb

@jippie what if the Monks cut down trees? Wouldn't that make them Trappist Loggers?

jippie

can't change the height of the desk because the lever is on the other half that is still downstairs (and too heavy for me to lift up the stairs)

it is like 60cm high now.

@rawbrawb whatever. you are just jealous

rawbrawb

@jippie Yep, so whats your point?

hey all, just listening to NASA Kepler mission live stream, news ...

jippie

19:03

?

The Photon

@rawbrawb Here's another one:

phy.mtu.edu/~suits/misc/tapsizes.html

rawbrawb

@jippie they are confirming that they've found 2 more rocky planets. Earth like, and MAYBE water on them (but not confirmed) in the habitable zone.

@ThePhoton cool

jippie

Does every electronics eval board (RPI, Arduino, ...) get its own stack?

angelatlarge

@jippie Stack?

jippie

stack

as in the exchange

Nick Halden

19:43

@jippie nope, no BeagleBoard.SE

jippie

@NickHalden I can propose that

Nick Halden

and no Launchpad.SE

jippie

@NickHalden 'cause nobody uses them

Nick Halden

Launchpad would have silly levels of duplication with arduino, and beagleboard would have silly levels of duplication with RPi

No Propeller.SE

jippie

yet

ok, ok, yo made your point :)

/me is out

@jippie Bye
