@SergiyKolodyazhnyy wut

WinEunuuchs2Unix

...I think he's busy rewriting code

Sergiy Kolodyazhnyy

@KazWolfe So I'm taking this class Digital Circuits 3, which is all about designing stuff in hardware description language called Verilog (which is what is used to program that board thingy). Now, there's couple of ways to write that code. One being behavioral. This is your usual C-like stuff. if, case, while, for statements and so on. Another way is data-flow, where you use boolean bitwise operators & | ^ and whatever else. Finally, there's the low-level stuff - actually defining gates

Well, in my infinite stupidity I wrote the code in gate-level stuff, which is not what the assignment asked

And just now with the power of vim and regex I've already rewrote the code, gonna test it on the board and go print that damn lab report. Hopefully I'll end up in class on time

Kaz Wolfe

wait... without a gate-level api, how can you even pass bits to the display?

Sergiy Kolodyazhnyy

That's the trick - Verilog does everything on gate level , AFIK. It's just syntactic sugar, if you will, for the programmer

Kaz Wolfe

ah.

so you just write bits to certain "variables"?

Sergiy Kolodyazhnyy

00:24

Basically, yes

Kaz Wolfe

huh, neat. i'll let you get back to work.

Sergiy Kolodyazhnyy

  9 module seven_seg_decoder(led_out,bin_in);
 10
 11     output [6:0] led_out;
 12     input [3:0] bin_in;
 13
 14     wire [3:0] bin_in_inv;
 15     assign bin_in_inv = ~bin_in;
 16

small snipped of my code

the [6:0] stuff is the bus, basically array

assign bin_in_inv = ~bin_in; basically flips all bits on that bus

37      //led_out[4] = A’D + B’C’D + A’BC’
 38      assign led_out[4] = (bin_in_inv[3] & bin_in[0]) |
 39                          (bin_in_inv[2] & bin_in_inv[1] & bin_in[0]) |
 40                          (bin_in_inv[3] & bin_in[2] & bin_in_inv[1]);
 41

And this one is the expression. So bunch of and expressions ored together

there's 6 more like that

Gosh, I love vim ! I've edited all those 7 expressions under 20 minutes

compiling this stuff takes forever though

so . . .my professor didn't understand my chicken scratch on the exam, and thought i didn't write the data-flow module, only behavioral. Which means he removed basically 30 points out of 45

Of course, my handwriting and whole exam were a mess, because i freakin panicked

WinEunuuchs2Unix

03:53

@NathanOsman Doesn't matter muru says I should have posted in stackapps where you post: askubuntu.com/questions/900319/…

Nathan Osman

Oh, yes. Stack Apps would be the right place.

If one of the Ask Ubuntu mods are around, I think they can push it there.

Sergiy Kolodyazhnyy

Why I can't install any firefox themes ? Why does it now ask me to install Persona extension ?

In the past i could install a theme without any of that

Nathan Osman

Firefox is moving away from classic add-ons.

Part of their new multi-process thing.

WinEunuuchs2Unix

@NathanOsman I don't have a stack apps account yet.... I'm not even sure if I'd fit in on that website. Besides I thought people around here would benefit most comparing their current code to what they posted in AU a year ago or more.

Sergiy Kolodyazhnyy

Well that's . . . weird as balls

Nathan Osman

03:59

@WinEunuuchs2Unix You can go to stackapps.com and click "Join this Community".

I think that's all there is to it.

WinEunuuchs2Unix

@NathanOsman Yeah I've joined 5 or more SE communities already that way...

Nathan Osman

@WinEunuuchs2Unix But I think you should just wait for a mod.

That will be the easiest thing to do.

They can move it for you quickly and painlessly.

WinEunuuchs2Unix

@NathanOsman Do I want something written for bash fans of AU and SO moved to an unknown site where bash may be frowned upon and it should be rewritten in C or something though?

Nathan Osman

@WinEunuuchs2Unix No, Stack Apps has literally everything. C, Go, Python, Perl, PHP, JavaScript, ActionScript, C#, you-name-it, etc.

I have some Ask Ubuntu tools listed there.

WinEunuuchs2Unix

We're talking 3 weeks of work for an AU / SO audience that will no longer be able to see the work and movement to an unknown audience.

Nathan Osman

04:06

@WinEunuuchs2Unix Here's what you do - post it on Stack Apps and then post on Meta.AU to bring attention to it.

Meta is a far better place for that sort of thing.

WinEunuuchs2Unix

No one goes to meta.

Nathan Osman

Heck, you could even create an ad :P

WinEunuuchs2Unix

LOL... well I guess I should go there but no time.

Nathan Osman

@WinEunuuchs2Unix Everyone on chat would see it.

Because all meta questions get posted in here.

WinEunuuchs2Unix

If I had known this would be the reaction I would have never had started the project unless I vetted this stackapps place first.

3 weeks is a lot of time....

Bash beginners like me in AU would appreciate the app... people there... I think they would laugh at it.

Even people like Terdon I think will be surprised what I did in bash.

Sergiy Kolodyazhnyy

04:18

@WinEunuuchs2Unix I am not surprised. I was doing the same stuff like you

Nathan Osman

I'm surprised.

If that counts.

Sergiy Kolodyazhnyy

If you look at my old scripts , i was writing things in bash for which bash isn't quite suitable, and would be far better implemented in Python

Still did it though

WinEunuuchs2Unix

@SergiyKolodyazhnyy Yeah... I've noticed some of your old posts and commented how I'm following in your footsteps a year or two behind :)

@NathanOsman Yes it counts if you're surprised :) I assume you mean in a good way...LOL

Nathan Osman

Oh, of course. I never would have thought Bash could be coerced into doing so much.

Very impressive.

WinEunuuchs2Unix

When all you know is Bash, every programming challenge you see looks like a nail.

WinEunuuchs2Unix

I read the book history of Ukraine discussing three princes of Kiev it was fascinating.

Sergiy Kolodyazhnyy

yeah, the Kiev Rus was quite interesting historical kingdom

I used to really like history

If I go there I'll probably have to install Arch Linux or something or native Debian and native Gnome.

Good one, Apple.

WinEunuuchs2Unix

@muru I don't know what you mean by writing for SE... Everything I've written has been Ubuntu orientated based on questions here. Systemd, UDEV and other stuff written is kind of universal but nothing to do with SE.

@ParanoidPanda you around? I should suspend you for using "how to do X?" as a question! We get enough of that from non-native speakers :P

WinEunuuchs2Unix

@Zanna The point muru was making is my latest Q&A belongs in stackapps instead of AU: askubuntu.com/questions/900319/… This means spending more time on a new site which could lead to most time on that site after awhile.

terdon

@WinEunuuchs2Unix I don't think he's right. You're not describing something that works specifically for stack exchange, are you?

The main problem is that you haven't posted a Q&A. You posted an answer as a question. Please edit that and ask an actual question to which you can post your script as an answer.

Ah no, it is indeed SE specific. So yeah, I guess it could well go to stackapps.

Could stay here, I guess, too but not in its present form. Everything on AU needs to be a question with a separate answer.

But yeah, stackapps would indeed probably be best.

WinEunuuchs2Unix

@terdon that project I've been working on these last few weeks... You helped a bit with progress bars and tee (which came out). You also helped with sed and herestring with 4k limit. I put SE reference in at the last minute in place of AU. TO gain more interest.

terdon

@WinEunuuchs2Unix Yes, I know. The issue is that you have essentially posted a blog post, not a Q&A.

WinEunuuchs2Unix

The problem was the answer doc wouldn't fit in the answer with the code. So I put the specifications into the question.

terdon

10:25

@WinEunuuchs2Unix You put everything into the question.

WinEunuuchs2Unix

The bash script is about 500 lines which takes about 20 KB and the answer limit is 32KB... I could split the answer into mutliple posts though.

@terdon I haven't posted the answer yet though....

terdon

@WinEunuuchs2Unix Oh? That's a question?

WinEunuuchs2Unix

@terdon Yes the same way people post questions detailing what they want.

terdon

@WinEunuuchs2Unix But your question already shows the script in action.

WinEunuuchs2Unix

Yes I could move the screens to the answer though

I just thought screen mock ups made the question easier to understand.

terdon

10:28

You could probably move everything to the answer. Just ask a simple question. "How can I scrape posts from SE and analyze them" or something.

And, if you don't want to be downvoted into oblivion, I strongly urge you to remove the parts that praise bash's "simplicity" as a programming language :)

It really, really, really isn't simple at all.

But that's your call.

WinEunuuchs2Unix

I will remove bash's simplicity right now and reformat Q&A tonight.

terdon

I would most certainly simplify the question enormously though. For one thing, nobody is going to read that.

Zanna

@terdon I think he meant it could work potentially work for any site on Stack Exchange...

terdon

@Zanna No, I had misunderstood the "question". I thought it was some sort of generic script and hadn't realized it was SE-centric.

WinEunuuchs2Unix

@Zanna Yes I wrote this for people using Ask Ubuntu to compare their current code to what they posted on AU long ago and forgot to maintain.

terdon

10:33

@WinEunuuchs2Unix Ah! There you go, that's your question then.

Now I understand why you were doing this :)

Zanna

haha I didn't get it either

WinEunuuchs2Unix

@terdon That was always the question from the very begining... I just wanted SO users or anyone else that uses SE HTML formatted answers to know they can use it too.

terdon

Yes, yes, I didn't mean SE as opposed to AU. I just meant SE generally.

When I first asked about stackapps, I hadn't realized your script was doing anything related to the stack exchange network.

WinEunuuchs2Unix

AU answers (and I presume all of SE) contain HTML formatted a certain way and the bash program can only scrape that.

terdon

Yes. But you don't mean your script is parsing the html, do you?

Zanna

10:35

my other thought was what does it have over SE data explorer...

WinEunuuchs2Unix

Yes it has to parse HTML to get answer up votes, question title, question upvotes.

terdon

@Zanna Presumably that you can diff against a local copy.

@WinEunuuchs2Unix Oh my. That, um, will break. Very fast.

The most minor change in format will render your script obsolete. You really, really don't want to go parsing html manually.

WinEunuuchs2Unix

It use's diff after writing AU answer containing only the matching code written to a new file.

terdon

But unless you happen to be one of the world's foremost Perl and regex experts as Tom happens to be, I do not recommend it.

Damn. I wish I'd realized what you were doing earlier. The whole thing can probably be done in >100 lines of code using the SE API.

WinEunuuchs2Unix

^^^ That's almost 10,000 upvotes in Q and all Answers.

terdon

@WinEunuuchs2Unix Yeah, probably the most famous SO post of all.

WinEunuuchs2Unix

I could post a link to my answer there, showing how it's done in bash.

terdon

@WinEunuuchs2Unix On your own head be it. I haven't seen your script but I bet you anything it isn't robust. Parsing html is a very hard problem without using a dedicated parser.

WinEunuuchs2Unix

The parsing HTML part is probably around 100 lines though. The screen interface and database maintenance takes a few hundred bash lines.

You'll see the code tonight... It'll take me at least an hour to write the answer and I have to run off to work soon.

terdon

10:43

I wasn't passing judgement on your programming skills, by the way, it is the nature of the problem itself. There is essentially no chance that you can do this properly using bash's crappy regex support.

WinEunuuchs2Unix

It's already working. I guess after posting the code people can shoot holes in it.

To find the file that needs to be diff it looks for <code> tag, finds three matching lines and writes file until </code> tag. I'd be surprised if they changed that.

terdon

@WinEunuuchs2Unix What if I have the string <code> in my code?

What if they add a class? Like <code class="foo">?

What if the tag is split across multiple lines?

What if there are nested <code> tags?

What if they use <CODE> instead of <code>?

See what I mean?

WinEunuuchs2Unix

None of the AU HTML uses upper-case for tags, except I think <QuestionID>

Bash scripts with <code> in the comments would not effect the diff command.

terdon

@WinEunuuchs2Unix None of the ones you've seen but there's no reason they won't in the future, that's valid html.

@WinEunuuchs2Unix Oh? And what if I do something like sed <code>outfile?

WinEunuuchs2Unix

If the AU HTML has multiple <code> tags it's the last <code> before your bash script that triggers writing to work file.

terdon

10:49

How can you know? What if I have multiple code blocks?

WinEunuuchs2Unix

@terdon It searches for <code> then three matching lines like "#!/bin/bash", "# This script sets UDEV...", "while true; do;".

terdon

@WinEunuuchs2Unix So it won't work unless my code i) has a shebang and ii) uses bin/bash?

What if the shebang is #! /bin/bash with a space?

Or #/usr/bin/perl? or anything else?

WinEunuuchs2Unix

It matches what's in your code file to what is posted in the answer. If the first three lines of your code file aren't in the answer it sets status to "3 Lines Not Found".

If your code file contains "Hello World", "How's it going", "I'm doing good" and the AU answer has those three lines then the match is made and writing for comparision occurs until </code>

terdon

@WinEunuuchs2Unix So it will break if my code itself contains </code>, for example.

WinEunuuchs2Unix

Yes it's not designed to compare HTML in your code file to HTML answers posted in AU. It's designed for comparing text files to code blocks posted in AU.

terdon

10:56

Sure, but code blocks could very well be scripts that produce html, after all.

So they could easily have something like echo "</code>"

WinEunuuchs2Unix

Yup as soon as it hits "</code>" it's like an end-of-file marker. It's not designed for comparing HTML to HTML. It's designed for comparing text to text.

People writing HTML code can't use this tool, they'll have to find another tool.

Sorry I have to run to get ready for work... I'll be back later.

@JacobVlijm I read the header and your answer is indeed specific to the question. I think it could also be an answer to the more generic question dupe-flagged (perhaps with a minor edit changing nautilus to programname. However it's my understanding that a merge cannot occur until a question is closed as a duplicate. Do you think your answer has more value to people only using nautilus or to people using any program under the Ubuntu sun?

@JacobVlijm to be clear I mean this one: askubuntu.com/questions/899317/…

Jacob Vlijm

@ElderGeek thanks for taking the effort to read! What I mean is that the dupe asks for a broad solution, literally "all windows", which justifies the -in my opinion- more heavy artillery. The heavy artillery also works for a single case, but a single case could also be solved with a lighter solution, hence no dupe.

Anwar

@edwinksl oh..sorry. I think you could ask a mod to remove the extra reps and lock it to 7777 :P

Jacob Vlijm

@ElderGeek So: if a user only needs a solution for one situation or application, the lighter solution does the job. Nautilus is extremely fit for this, since the time the window appears is reasonably predictable, unlike e.g. Inkscape.

Uhg, don't you just hate questions like this?

Q: How to remove unmount drive on ubuntu?

Please help me put password for eject and unmount. I want to block unmount hard disk drives or I want put password for that, why means I face a big issue on Ubuntu. And I cannot login to windows 8 UEFI, and I format my whole HDD. But one thing now I put windows 7 64-bit on legacy mode. Please ...

12.04 dual-boot

Seth

@JacobVlijm it's not your job to make people perfect

Elder Geek

@JacobVlijm I would think that the time involved for a window to appear would have many variables (system load, hardware latency, etc.) making predictability uncertain.

Jacob Vlijm

@Seth no, but I'd like to prevent an incorrect dupe :)

Seth

14:28

@JacobVlijm yeah, in case of dupes it's usually fine. The question should be edited.

aaaaand false positive. My laptop had connected to my comcast modem and not the dd-wrt router.. I didn't get IPv6 working :(

Jacob Vlijm

@ElderGeek will get back, have to teach :)

Elder Geek

@AndroidDev Yes, that's a horrible question in a number of ways.. Too broad, partially off topic, I'm going with too broad.

Anwar

@SergiyKolodyazhnyy is there any option to use --depth=1 with vundle?

Android Dev

@NathanOsman But SP can record the desktop, not just game. Or can AMD's tech do that too?

Anwar

found this but it seems it's not been merged yet

found the answer. not possible

Android Dev

14:36

@Rinzwind, askubuntu.com/questions/900469/… That's what I thought too, but then I realized I misread it

Rinzwind

@AndroidDev can't be fastboot.that would have erased the file (since that copies the hibbersysfile over the partition)

Seth

@ThomasWard do you have any experience getting IPv6 to work with dd-wrt?

Android Dev

"sudo command runs automatically just after plugging in the pen drive" - That would be a HUGE security fail — Android Dev 9 secs ago

Just like on XP...

Thomas Ward

@Seth nope.

pfSense, not dd-wrt, here.

Seth

:/

@ThomasWard nice

Thomas Ward

14:44

well I apparently have outdone myself setting up a mail server... just added greylisting now it works better lol.

NOTHING bad is getting through to my mail lol

Harsha

14:54

Hey

Rinzwind

@AndroidDev read between the lines of my question ;)

Harsha

does anyone here know how to setup React js in Ubuntu?

Rinzwind

@ThomasWard hand over the email adress! I accept the challenge

Harsha

I'm struggling with it for quite some time now!

Rinzwind

@Harsha blog.tamizhvendan.in/blog/2015/11/23/… :+)

Anwar

14:56

@Harsha You were trying to use with?

Harsha

@anwar what do you mean by that/

is it necessary to install Babel 6 and Webpack too?

Anwar

for example if you were trying to use with a framework...

Harsha

well, all i know is that I need to make a little UI with it.

I'm a newbie to javascript and react of course so I find all this confusing.

I just learnt javascript and now I'm headed towards React.

Seth

ok I got radvd working and I have a proper IPv6 address now (I think) but I still cannot connect to anything because of DNS issues.

Journeyman Geek

>_>

@Seth last I tried ddwrt it had no ipv6 support at all

try ping6 and an ip address?

Anwar

15:04

@Harsha I think you can use react easily with any js project. You need to link the js files. I used it 5-6 months ago and am not actively using it. Their documentation would be more helpful i guess

Seth

@JourneymanGeek it does now. The router gets its own IPv6 address and can ping ipv6.google.com et al.

Rinzwind

@JourneymanGeek it does suport ipv6 :)

+p

Journeyman Geek

ah

Do the clients have valid ipv6 addresses?. In theory you could just set a seperate dns server for those?

(mine just works ;p)

Rinzwind

hmm it does at least since 2013 ( see dd-wrt.com/wiki/index.php/IPv6 )

Seth

@JourneymanGeek I think they do now, yes.

By separate DNS do you mean in /etc/resolv.conf?

The host can't contact anything over IPv6..

Harsha

15:07

I"m trying according to the blog suggested,

above and when he asked to "create the index.jsx file in the ./src/client/app", what does he mean?

Seth

can't even ping the IPv6 default gateway.. strange.

cl-netbox

Hello everybody ! :)

Journeyman Geek

@Seth possibly talking out of my ass here.

My ipv6 just works so... ;p

and both my routers do it natively

Sergiy Kolodyazhnyy

@Anwar not familiar with vundle, sorry

cl-netbox

Yesterday I installed fedora 26 alpha in a VM and guess what @SergiyKolodyazhnyy ? That thing is already quite stable and really rocks ... kernel 4.11 - xserver 1.19 - mesa 17.3 ! :)

Sergiy Kolodyazhnyy

15:22

so, our first project in verilog class will be the traffic light control. EGGSCITING, right ?

Jacob Vlijm

@ElderGeek Absolutely, but while an average Inkscape window will appear within 3-10 seconds, nautilus' Home window wil practically always appear within 0.5 seconds, which provides a usable option for this case.

Sergiy Kolodyazhnyy

@cl-netbox Nice ! Personally I decided to never go back to Fedora. CentOS ?yes, but no Fedora

Anwar

@SergiyKolodyazhnyy which one do you use?

Jacob Vlijm

@ElderGeek The comment below the answer is incorrect btw, nautilus does not block sleep from exiting.

Sergiy Kolodyazhnyy

@ElderGeek exactly, and that is why i am slowly moving away from timing approaches. It is too much of a gamble

cl-netbox

15:25

@SergiyKolodyazhnyy You really should overthink your decision ... it changed a lot since Matthew Miller took over the project lead and invoked fedora next ... a very good distro today ! :)

Sergiy Kolodyazhnyy

@JacobVlijm Once i get to work, i can show you the output of my command. Maybe it is nonblocking on your system but it does not work for me

At least make nautilus run in background

Seth

@JourneymanGeek I think I may need a route.

Sergiy Kolodyazhnyy

@cl-netbox well, maybe i will try a vm. but actual install probably wont happen

cl-netbox

@SergiyKolodyazhnyy okay ... for which reason ? negative experience in the past ?

Sergiy Kolodyazhnyy

@cl-netbox yup, exactly that

cl-netbox

15:29

@SergiyKolodyazhnyy was the same with me ... I dropped it for many years ... then tried newer editions ... and was convinced ... they changed a lot ! :)

Sergiy Kolodyazhnyy

besides, Fedora is like a playground for experiments before they go into RHEL. I avoid dev releases. I need stable OS to get my tasks done

TheXed

@SergiyKolodyazhnyy don't lie, everyone already knows you don't get tasks done...

Sergiy Kolodyazhnyy

@TheXed At least I aspire to do so.

I maybe a proctastinator but I am trying to ammend my ways

TheXed

I aspire to feel my foot...but I don't know if that will ever happen again...

Sergiy Kolodyazhnyy

@TheXed and what is wrong with your foot today ?

Jacob Vlijm

15:35

@SergiyKolodyazhnyy it totally makes no sense. sleep does not start before the non-blocking command has finished. No point in making it run in background. See: dropbox.com/s/protjk565wom1rb/…

^ as you can see, the command exits.

cl-netbox

@SergiyKolodyazhnyy exactly that changed ! fedora 25 is a stable release, not a dev version ... rawhide is for experiments - fedora 25 is as stable as ubuntu 16.10

Sergiy Kolodyazhnyy

@JacobVlijm tell me , if i run firefox && echo hello, will echo output text right after firefox window appears or wait till window closes ?

that is the point i am making

problem isnt with sleep, it is with nautilus

It may be the behavior of your version of nautilus, but it is not the same accross releases.

Jacob Vlijm

@SergiyKolodyazhnyy Again, nautilus is not blocking. The question is on nautilus. ALso tried on 14.04, exactly the same.

Try it, show me the screencast and I'll believe you. Quite frankly, I don't see it happen.

Sergiy Kolodyazhnyy

@JacobVlijm ok, will show as soon as i arrive to work

anybody else in chat wants to verify the behavior of nautilus ?

Elder Geek

@JacobVlijm Thank you for your response. I think I understand where you are coming from, but I'm not convinced that it's wise to make assumptions on timing with all the variables involved.

Jacob Vlijm

15:45

@ElderGeek usually, I agree, even made scripts to wait for the window. In many cases on AU scripts involving windows, I do. In this case, try it for a week and you won't have a single case of failure (I tested it for days now).

Sergiy Kolodyazhnyy

@JacobVlijm also, please stop editing posts with requests to stop close votes. It is not information that should be put into question and belongs comments.

Let peope make their own decisions

Jacob Vlijm

@SergiyKolodyazhnyy please read higher up. Already discussed with mods. You also may have forgotten this one: meta.askubuntu.com/questions/15313/…

tomsk

hellooo :)

cl-netbox

@tomsk Olé ! :D

Anwar

I just read that question. As window placement is handled by compiz, it should be cleared using compiz I think. Also, I believe OP somehow messed their compiz config

tomsk

15:49

@SergiyKolodyazhnyy my script LLI for KDE is almost done, i find a config file, but i dont know how to reload it :D without restarting plasmashell

Jacob Vlijm

@Anwar mind that this is normal behaviour, happens similarly here, be it on another position. Your opinion on how to solve this should not decide if it is a dupe or not.

cl-netbox

@JacobVlijm @SergiyKolodyazhnyy Are you still discussing on that question from the other day about whether CCSM beats xdotool or the other way around ? :D

Jacob Vlijm

@cl-netbox No, we are discussing incorrect dupe marks.

cl-netbox

@JacobVlijm ay ay ay :D by the way, good afternoon Jacob ! :)

Anwar

@JacobVlijm let me re-think..

Elder Geek

15:52

@cl-netbox Good day

cl-netbox

@ElderGeek Thanks ! :) Same for you ! :)

Elder Geek

@cl-netbox So far so good, thanks!

cl-netbox

@ElderGeek nice ! :) What about the water ? Could you save your house ?

@ElderGeek I mean the flood you talked about the other day ... could you prevent the water coming into the house ?
