@jippie Hah! @coding_corgi has a good point. You forgot to consider the incentives for the throngs of your followers.

@jippie Of course your answer-fu might be so strong...

jippie

@angelatlarge I won't be the only one with the downvotes and I said I needed just over 50 rep per day, that is including downvotes.

angelatlarge

@jippie You sir, also have a good point: downvotes are painful to the ego, but much less painful to the rep score.

@jippie 5:1 right?

jippie

@angelatlarge don't know

angelatlarge

@jippie -2 for each answer downvote; +10 for each upvote, so you need 5 dvs to cancel out a single uv.

jippie

oh

yes

@angelatlarge then again, if I get grumpy for not being able to retire, I might start random downvoting too.

coding_corgi

20:09

@jippie Ooh yea! That's fun! ;]

angelatlarge

@jippie Many of your followers have very little rep that can be downvoted :)

jippie

@angelatlarge yup I can burn them down to 1

unable to chat or vote

angelatlarge

@jippie Hmmm.. doesn't look like it, unless you can recruit some accomplices

@jippie Looks like given the right curcumstances you could take 7pts of @coding_corgi's rep, if I am not mistaken.

@jippie It is like a DDoS attack: no robots, no DOS

Hi

are imaginary numbers observable?

If I observe the behavior of two signals to behave as functions of complex frequency (complex numbers) and this behavior is visible in data, have I observed imaginary numbers in the sense that their properties are observable?

coding_corgi

@angelatlarge Booo you!

@angelatlarge Grrrrrr.............

angelatlarge

@coding_corgi I shouldn't talk about DDoS either?

@EwokNightmares Hi

coding_corgi

@angelatlarge You shouldn't be talking about anything Lugo!

angelatlarge

@coding_corgi What's Lugo?

coding_corgi

@angelatlarge A south-american dictator that broke all the rules, but if you want to go for popularity, here ya go Chaves!

angelatlarge

20:39

@coding_corgi This gentleman?

Fernando Lugo

Fernando Armindo Lugo Méndez (; born 30 May 1951) is a Paraguayan politician who was President of Paraguay from 2008 to 2012. Previously he was a Roman Catholic priest and bishop, serving as Bishop of the Diocese of San Pedro from 1994 to 2005. He was elected as President in 2008. In 2012, he was removed from office through an impeachment process that neighboring countries deemed a coup d'état. Early life He received his basic education at a religious school in Encarnación, and sold snacks on the streets. His family was not particularly religious; by his own account, he never saw his ...

coding_corgi

@angelatlarge Duh!

angelatlarge

@coding_corgi Ok, and what does it have to do with DDoS?

coding_corgi

@angelatlarge gentleman? YOu must be out of your mine,

angelatlarge

@coding_corgi Oh, is that a lady?

coding_corgi

@angelatlarge Just calling people dictators... DO you like the name Kim Jong ...

@angelatlarge No, a male, he is not a 'gentle' man

angelatlarge

20:40

@coding_corgi thefreedictionary.com/gentleman

@coding_corgi See definition 4

Anindo Ghosh

@jippie I linked another question because that one needed an answer. Then I commented on YOUR answer to a separate question, because I figured you would know which answer I was referring to :-)

coding_corgi

@angelatlarge Your getting on my last nerve

angelatlarge

@coding_corgi This is not the first time you make unwarranted assumptions about meanings of words. See for instance thefreedictionary.com/bastard

coding_corgi

@angelatlarge SHUT UP!

Anindo Ghosh

@jippie Actually, the site saves a draft of the post till you publish. I routinely leave drafts over hours or days.

jippie

20:43

@AnindoGhosh but I misread @AnindoGhosh

@AnindoGhosh i don't feel comfortable without clicking save

or post

or whatever

angelatlarge

@coding_corgi Well, that's a nice "how do you do"...

jippie

@AnindoGhosh I did attempt to answer the linked question BTW

coding_corgi

@jippie Mebe you have OCD?

@angelatlarge You must be drunk.

angelatlarge

@coding_corgi Not yet. Too early.

Anindo Ghosh

@angelatlarge I can vouch for that.

@angelatlarge I'll find the refs tomorrow and let you know. It's 2:16 am and I just returned from a party.

angelatlarge

20:46

@AnindoGhosh You are a good-looking man @AnindoGhosh :)

@AnindoGhosh Thanks.

jippie

@coding_corgi what is wrong with my brain is between me and my psychiatrist

coding_corgi

@angelatlarge You my friend, shall be referred to a 'nice' moderator (meaning the principle that's on MY side), your dictatorship behavior is VERY annoying, please leave chat for the next 2 hours....

jippie

@AnindoGhosh party animal

Anindo Ghosh

@NickHalden They did 3.3 Volts on the Due, and a couple of other boards... they also had a short run of Nano boards at 3.3 but gave that up. The Due is not an AVR by the way.

coding_corgi

@jippie Of course not, the second you leave your psychiatrist starts cracking up, tells her/his coworkers, before you know it it's all over the net,

Anindo Ghosh

20:48

@NickHalden Also safe frequency at 3.3 V is 8 or 10 MHz, I can't recall. Not 16.

@jippie USB drops low enough that 4.5V is not assured after the MOSFET.

jippie

Speed Grade:
– 0 - [email protected] - 5.5V, 0 - [email protected] - 5.5.V, 0 - 20MHz @ 4.5 - 5.5V

coding_corgi

@angelatlarge I said LEAVE!!!! Now? ;]

Anindo Ghosh

@angelatlarge Context please? (Finally caught up with this message)

jippie

15MHz will be half way between 2.7 and 4.5 = 3.6V according to the graph in the datasheet,

Anindo Ghosh

@jippie Yep, that's correct. 4.5 is not assured on real world USB ports.

@jippie Also true.

@jippie I upvoted your clamping diodes, as you probably noticed.

angelatlarge

20:55

@AnindoGhosh I think we had some crossed wires. Here's how I thought it went:

2 hours ago, by angelatlarge

@coding_corgi Or sleeping with someone in charge

Anindo Ghosh

@angelatlarge yes

angelatlarge

10 mins ago, by Anindo Ghosh

@angelatlarge I can vouch for that.

Anindo Ghosh

@angelatlarge And I vouched for that.

@angelatlarge and you therefore concluded I am a handsome man?

jippie

@AnindoGhosh I never really try to analyze who upvotes my posts.

angelatlarge

@AnindoGhosh I commented that you are handsome enough that you could have first-hand experience with the fact that sleeping with someone in charge works. And now the joke is soooo dead.

Anindo Ghosh

20:58

@angelatlarge Hmm, even if I were the dominant in what I vouched for, I still don't quite get it. And no, I was vouching for being the supplicant ;-) Won't say more on something that gets logged for posterity.

angelatlarge

@AnindoGhosh Hmmm.. It is true that I was considering the issue from one side only, but perhaps in my defense I can say that such issues are usually seen with enough clarity only from one side, not the other.

vvavepacket

guys, which u prefer, VHDL or Verilog?

Anindo Ghosh

@angelatlarge I prefer both sides ;-)

@vvavepacket And for this question as well, I prefer both sides ;-)

jippie

I was considering a one day FPGA workshop for €149 including hard- and software, but it turns out I need a Windows laptop. I don't own a laptop (nor Windows license)

coding_corgi

@jippie AHHHHHHHHHHHHH!!!!!!!!!!! WHAT IS UP WITH EVERYONE TODAY?!!?!

David Kessner

21:05

@vvavepacket VHDL

vvavepacket

@AnindoGhosh well anindo, ur a very multi faceted engineer.

Anindo Ghosh

@jippie Ahh just buy a cheap FPGA dev kit off eBay... I know you're smart enough to figure it all out over time.

vvavepacket

but which is ur main RTL design language?

David Kessner

@coding_corgi I'M FINE! HOW ARE YOU DOING THIS FINE DAY?!?!?! :)

Anindo Ghosh

@vvavepacket You don't know the half of it. I'm better known as a photographer than a technology person of any flavor. :-)

jippie

21:06

@AnindoGhosh I do like the flying start, especially for that money

and if I buy a dev kit, I still need the software (and Windows and a computer that runs it)

coding_corgi

@DavidKessner Again? Really? See what I mean @all?

Anindo Ghosh

@jippie Fair enough. Are you sure you wouldn't get exasperated at the "least common denominator" speed of teaching?

jippie

@AnindoGhosh for a single day?

Anindo Ghosh

Right, where do I go and mute the corgi?

7

coding_corgi

@AnindoGhosh Yes, I thought you were just a geek, not a photographer...

vvavepacket

21:07

Anindo, can I specialize in 2 things at the same time, like FPGAs and DSPs?

jippie

@AnindoGhosh I only know FPGA's from pictures

Anindo Ghosh

@jippie You'd be twiddling your thumbs half the time, waiting for the others to catch up.

jippie

@vvavepacket maybe a soft-DSP kernel exists for FPGA?

coding_corgi

@AnindoGhosh You can't. The corgi mutes you.

angelatlarge

@coding_corgi +1!

vvavepacket

21:08

@jippie, i think so

@AnindoGhosh youre very active here in chat

angelatlarge

@coding_corgi In Soviyet Rasha...

David Kessner

@jippie I've done lots of DSP-ing in FPGAA's. But I have always done my own logic for the math.

Anindo Ghosh

@vvavepacket That's like asking if you can do analog and digital electronics... It depends: Can you juggle tennis balls and chew gum at the same time?

coding_corgi

@angelatlarge AHHHHHHHHHHHH!!!!!!!!!!!!!!!!!!!!!!

@angelatlarge You can't +1 in chat!

jippie

silence

Anindo Ghosh

21:10

@jippie Someone I know, who's bright, but perhaps a smidgen less so than you, did his first blinkenlights on a cheap FPGA in an hour, and a serial communication protocol translation thingie in a week or 10 days.

coding_corgi

@jippie EVERYBOdY! PLeAse listen to this CrAZy man!!!!!

@AnindoGhosh I told you LISTEN!

Anindo Ghosh

@vvavepacket Yes, and not just EE chat. About 3-4 other chats in various subject areas across the internet.

vvavepacket

well im really confused. i have 2 sets of pdf here. 1 is vhdl, 1 is verilog. confused where to begin with. (its the same book except there are seperate ones for different language)

jippie

@AnindoGhosh I'm not as smart as I look in my avatar.

vvavepacket

@Anindo really smart looking in the avatar

coding_corgi

21:12

@jippie You must not be very smart then...

@CamilStaps HELP MEEE!!!

jippie

@vvavepacket watch out what you say, I may very well put you on mute too ;o)

vvavepacket

@jippie sorry

user61389

Ehm. No?

jippie

(hope that muting thing isn't a room wide thing)

coding_corgi

@jippie Where is @Kortuk or @W5VO? We need order here!

vvavepacket

21:14

@jippie, did i do something wrong?

Anindo Ghosh

@jippie No, it's mute-an-individual-just-for-your-sanity

coding_corgi

@vvavepacket don't listen to him

user61389

Good idea.

jippie

@vvavepacket no worries, just teasing you a bit

Anindo Ghosh

@vvavepacket He's clowning around.

vvavepacket

21:14

ohhh

i was like, omg, jippie is a moderator here..

Anindo Ghosh

Okie pplz, I need to go sleep. Been up for 21 hours now, and have to be back up in 3 hours. Bye all!

vvavepacket

sleep tight

jippie

good night @AnindoGhosh

angelatlarge

@AnindoGhosh Goodnight puppet master

user61389

Only owner. I'm owner too, it can't be a great responsibility.

user61389

21:15

Night @Anindo

Anindo Ghosh

@vvavepacket He is a room owner, but that doesn't mean he can mute someone for the entire chat membership. Just for himself.

vvavepacket

tnx anindo for the info

Anindo Ghosh

Play nice people, that'll really rile up the beards!

jippie

@AnindoGhosh I can refuse entry to the room I believe ...

angelatlarge

@vvavepacket Everyone and their aunt Sally is a "moderator" here.

jippie

21:16

@AnindoGhosh yes sir!

Anindo Ghosh

@jippie Nope.

angelatlarge

@vvavepacket @AnindoGhosh is a very liberal dictator

2

jippie

@AnindoGhosh oh right, it says 'explicit read' and 'explicit write' access

angelatlarge

@vvavepacket He is the Alberto Fujimori of chat rooms

user61389

Btw @angelatlarge about my obsession; the idea is one edit will prevent multiple future thankses, and I try to only edit such things when the post is on the front page already.

user61389

21:21

For the rest, yes, I'm obsessed :-)

angelatlarge

@CamilStaps That's the funny thing about obsessions: the obsessed usually do have some sort of explanation that makes sense to them. So we can't rely on our own intuition for judge our own sanity.

user61389

:-)

jippie

@angelatlarge you mean like:

May 9 at 7:01, by jippie

@angelatlarge Girls don't speak C18 nor SPI, so @CamilStaps can't communicate with them

that is sort of similar, obsessed with C18.

no need to talk to 'devices' that don't 'speak' C18.

angelatlarge

@jippie But, on that subject, 16 is not a good time to be concerned with people they might be romantically interested in, especially for a dorky person. At that age only young people who usually turn into __holes are good with romantic-type relationships.

jippie

@angelatlarge I'm still not 'good' with girls.

angelatlarge

21:31

@jippie Better than at 16 or 18, no?

jippie

@angelatlarge nope

angelatlarge

@jippie Hmm.. you are raining on my parade

jippie

@angelatlarge Obsessed with them, but I don't understand them either ;o)

angelatlarge

@jippie Understand != good with

@jippie I think "my parade" is something I wish I heard more of when I was younger.

The Photon

@EwokNightmares I think that is a philosophical question --- probably there's no one right answer.

jippie

21:33

@angelatlarge is that a compliment to @CamilStaps?

user61389

@jippie I switched to XC8, better? :-)

jippie

@CamilStaps Let's check with @angelatlarge

angelatlarge

@jippie That depends. I don't know his personal life

@CamilStaps Equally good.

user61389

I'm not really interested in sharing details ;-)

angelatlarge

BTW, does anyone know a good way of getting true URLs out of google results page?

jippie

21:41

What is the correct letter for battery capacity in mAh?

vvavepacket

guys, arent no LOVE se?

user61389

C?

user61389

No, Q, it's charge

vvavepacket

mAh is a unit of energy

so W?

oops

J?

user61389

No, E=P*t, not I*t

The Photon

21:48

@vvavepacket milliamp-hours is literally a unit of charge. Practically that might be considered as a unit of energy if you know the voltage...

MLM

@ThePhoton I decided to make a question on it:

Q: Fix Conflicting IO Standards

I am using the Basys 2 Spartan-3E FPGA board with Xilinx. I need the pmod i/o to be at 1.8v so I am using LVCMOS18 IOSTANDARD. You can find all of the IOSTANDARD's available for Spartan-3E in this document. Whenever I try to compile my project it always errors out on the Place & Route phase tha...

user61389

I'm out, good night

The Photon

@MLM My only suggestion is to try specifying the IOSTANDARD in the UCF, instead of relying on the default...No reason that should change the behavior, but there's no reason evident why you should have any error at all.

angelatlarge

21:51

@CamilStaps Goodnight

vvavepacket

@thephoton, thanks i get it

jippie

time for bed

/me is out

clickkkkk

MLM

@ThePhoton :/ - its kinda weird how it compiles without setting the iostandard to those pins but then it is not 1.8v

The Photon

@MLM The error message makes no sense. It's saying LVCMOS25 input conflicts with LVCMOS25 output, which is crazy.

Actually that's not even right.

It's saying LVCMOS25 conflicts with <<<<nothing>>>>

vvavepacket

@jippie byee

MLM

21:55

@ThePhoton 0.0 great...

if that is not possible, then I guess I have to level shift it

The Photon

@MLM Given what you've shown, it looks like a bug --- LVCMOS25 on bank 2 shouldn't conflict with LVCMOS18 on bank 0 or whatever.

MLM

@ThePhoton ill try to just exit out and create a whole new project

The Photon

Have you doublechecked the pins are really in the banks your comments say they're in?

MLM

@ThePhoton no, i tried to look but I only know because of the ucf file download on digilent

those are the default comments they give

The Photon

@MLM Then it's worth doublechecking against the datasheet.

MLM

22:11

@ThePhoton checking btw

MLM

22:21

Made a good reference image and updated the thread. Gtg eat but will double check @DavidKessner answer when I get back.

anorton

@coding_corgi I just got my Raspberry Pi in the mail! Yes, it was USPS, but it arrived in like 2 days... :D

vvavepacket

@anorton, how much was it

anorton

39.95 (adafruit... I had other things to order from them, so shipping was better that way.)

angelatlarge

22:52

@anorton Are you still here?
