edwinksl

Serg

@edwinksl i read your mind, because i just added it bro

edwinksl

:P

but no c...

Byte Commander

I request a Lisp solution, @Serg!

:P

Serg

lol jk don't waste your time

Serg

@ByteCommander but. . . but . .. i don't speak Lisp yet . . .

Byte Commander

Is that my problem?

Oh, and brainfuck please, while you're at it.

Serg

/facedesk

Byte Commander

I don't dare you to write it in duck duck goose though, that language is a bit too verbose...

Serg

I'll just go write Turbo Pascal or BASIC

Rinzwind

9:28 AM

@Serg I still use BASIC <3

Serg

@Rinzwind which version ?

Rinzwind

Thoroughbred BASIC 8.8

Serg

In case anyone in the sort of depressive mode , youtube.com/watch?v=QfpY2bpEw4M

terdon

@Serg Nice one!

Serg

^_^ Thanks

You could further golf the perl one to perl -plae '$_=join" ",reverse(@F);' input.txt but I'm impressed! Serg posting a perl approach, whohooo!

The -a already does the split for you, by the way. In your original approach, the -a was not making any difference since you weren't using the @F array and were instead splitting manually.

Serg

Lately, I've been playing with Perl more and more, because sometimes python is already taken , lol. Is @F array built-in variable, like $_ ?

terdon

@Serg Yes, when used with -a. That's what -a does.

       -a   turns on autosplit mode when used with a -n or -p.  An implicit split command to the @F array
            is done as the first thing inside the implicit while loop produced by the -n or -p.

        An alternate delimiter may be specified using -F.

Serg

Neat. Gotta remember that

terdon

@Serg While I have grudgingly come to respect and am even starting to like python, there is no question that perl is better for text parsing one liners.

edwinksl

"even starting to like python"

2017 already has surprises

terdon

9:40 AM

:P

Serg

Yeah, as far as one-liners go , Perl definitely is shorter and more succinct

@terdon Question , can Perl access C-level functions, such as seek() ?

Rinzwind

@terdon perl was intended for that so no suprise :P

I like python more though :D

Serg

I like Python for the variety of modules and allows low-level access to data, closer to C

Rinzwind

with less than 10 hours of experience in python I made a SQL to XML export

(25 years of coding experience though ;-))

BLUE FLAGS and then they are all in RUSSIAN

Serg

woah woah woah, 11 chat flags ?

Rinzwind

9:49 AM

yeah 11 now

Serg

I can't load them

Rinzwind

Ok, there's that room ?

Q: Accidentally uninstalled dnsmasq-base on Ubuntu 15.04

Ran sudo apt-get remove -y dnsmasq-base dnsmasq-base on my Ubuntu 15.04 machine. Now I can't connect to the internet (Etherenet or Wifi). I have manually installed dnsmasq-base version 2.72 from a tar.gz and have run "sudo service network-manager restart" but nothing. When I go into System Settin...

"accidentally"?

terdon

@Serg Yes. Check out perldoc -f seek

Hello guys i know there is someone who uses or has used supervisor on ubuntu...i just started to learn this and i don't know how to make supervisor work at reboot... i have created my .conf file where i have set the process which i want to run and when i start supervisor with service supervisor start all is fine till server reboots...then i need to start supervisor again

Serg

You can add that command to /etc/rc.local , like service supervisor start &

I'd check logs through, because it sounds like your service is failing to start for whatever reason

lewis4u

in which log may that be

where is the log file for startup

OS start up

i get an error permission denied

maybe because the supervisor conf is made as a root

for my process i mean

Serg

10:24 AM

use journalctl command or sudo cat /var/log/syslog

lewis4u

yes i have found it, but there is nothing about mine process

Serg

10:40 AM

well, i don't know then. Just use /etc/rc.local like i showed before. That's a workaround. Not ideal, but at least you don't have to type that command each time

lewis4u

i had to run systemctl enable supervisor and now it works

According to The Register, lots of Amazon Echo devices were accidentally triggered by a presenter saying 'Alexa ordered me a dollhouse'. Telly station CW-6 said the blunder happened during a Thursday morning news package about a Texan six-year-old who racked up big charges while talking to an...

I mean, seriously, who the hell buys these things?

"Yes, please, I'd love to have a device that records my speech and sends it to one of the largest corporations on the planet and even buys stuff I have to pay for. No, I'm not brain dead, why do you ask?"

A: How can I stop Alexa from ordering things if it hears a voice on TV?

If you hit the Alexa input devices with a 3-round burst from an AR-15 or similar device, that ought to disable it.

that answer is gold

I wonder if it has any upvotes.

terdon

s/AR-15/hammer/ and I'd agree.

@ByteCommander Yes, +2

Don't you see them?

Byte Commander

Don't have the userscript for showing up/down on my study computer.

terdon

Ah, right

Q: What ever happend to clean up week?

Going off Elder Geeks post here where clean up was discussed, what happened to clean up week? It seems to of only run for one week, years ago. What happened to it and could we bring it back? The user base is bigger now and I think many would take part. Opinions?

@George - answers go in the answers. — Aaron Hall 59 secs ago

@terdon I had an edit on this question - was I right here? ^^^

terdon

@AaronHall In that answers should be answers? Yes, of course.

Note that George didn't add the answer, he just changed Upd to Update. He's a new user who's been very active lately (and very helpful) but is still learning the ropes.

And, as you just saw, he learns fast and is open to suggestions :)

Be like George!
