Should we start considering questions specific to 14.04 off-topic? I haven't seen any question related 14.04 asked after 17 April getting closed as off topic.

WinEunuuchs2Unix

00:54

@Kulfy Doesn't 14.04 get some sort of extension if they pay extra?

Kulfy

01:07

@WinEunuuchs2Unix They do but AFAIK ESM isn't supported here on Ask Ubuntu. It's a Canonical Ltd.'s thing.

Like 12.04 reached EOL in 2017 but it's ESM is ending in April 2019 (which is also about to end). Thomas announced it as off-topic in 2017.

WinEunuuchs2Unix

01:29

@Kulfy Hmm... So we have to Ask Ubuntu (Canonical) if ESM is supported on Ask Ubuntu? :/ I tend to agree with you but still one has to wonder... If you purchase extended life support do you escape EOL (End of Life)? If so you and I have no way to verify a question "I have Ubuntu 14.04 with ESM to avoid EOL and this problem occurred..."

Kulfy

Canonical’s Ubuntu security team provide fixes on high and critical CVEs (common vulnerabilities and exposures) for the most commonly used server packages in the Ubuntu main archive. ESM provides the essential continuation of the security updates for 12.04 LTS (Precise Pangolin) and 14.04 LTS (Trusty Tahr) that Ubuntu users have always received via a secure, private archive.

@WinEunuuchs2Unix They get security updates only via private archives. So we don't know which version of which package is available, which packages are still supported, what package is causing problems (probably that's why user is on AU). I am not sure about ubuntuforums but here it is off-topic.

WinEunuuchs2Unix

02:14

@Kulfy My Ubuntu 14.04 is borked on my third laptop so personally I'm not effected. Apart from that I'm on 16.04 and Kernel chain 4.14 LTS so good for a few more years. I agree with your 14.04 + ESM analysis.

Kulfy

02:53

@WinEunuuchs2Unix Is it on kernel 4.14? I thought it must be on 4.15 since on launchpad xenial got bionic's kernel on 2nd August. My bionic is running on 4.15 and I occasionally use xenial mostly in VM.

WinEunuuchs2Unix

@Kulfy 4.14 is a LTS kernel for 5 years. Currently I'm on 4.14.110 but just downloaded 4.14.114.

St. Louis Blues just beat Dallas Stars (I digress :))

Kulfy

@WinEunuuchs2Unix Oh you compiled yourself?

WinEunuuchs2Unix

@Kulfy Haha no I'm too lazy to compile a kernel. Here:kernel.ubuntu.com/~kernel-ppa/mainline/v4.14.114

I like to stick to the same LTS kernel chain. The other ones like 4.15, 4.16, 4.17, 4.18, 4.19 and 4.20 seem to disappear overnight and it's too hard to read up on developments in Linux World. If that makes any sense?

Kulfy

I tried to compile kernel about a year ago and got lots of error. I used to think that once Ubuntu releases kernel for their release, it the responsibility of Ubuntu to modify and minimize bugs. Was I missing something?

WinEunuuchs2Unix

I dunno. I've only compiled small things like drivers and grub. Nothing big like the kernel.

Compiling grub was a headache but I did manage to change countdown timer from 1 second intervals to 1/10th second units: stackoverflow.com/questions/51341871/…

Zanna

03:09

@Kulfy you got lots of errors compiling, or when using the kernel?

Kulfy

@WinEunuuchs2Unix Is it BURG?

@Zanna During compilation. I tried a year back. It was something like Deb error. Felt too lazy to even try again.

WinEunuuchs2Unix

@Kulfy The only thing I know about Burg is it's Grub spelled backwards. No It's grub I compiled. Kind of fun but I don't want to do it again.

Zanna

Compiling stuff is hard

I've compiled the vanilla kernel a number of times

the errors I got on early attempts were easily resolved by installing packages

but the Ubuntu kernel has way more drivers than any kernel I compiled. I was using a .config someone wrote for my device, with only the drivers it actually needs

WinEunuuchs2Unix

Yeah compiling grub requires all these preconditions be set and options invoked. It took awhile to find the one line of code to be changed granted, but a super long time to dot the i's and cross the t's for successful compilation.

Kulfy

@WinEunuuchs2Unix I haven't used BURG. I only heard about it. I started using Linux in 2015 and developed interest in late 2016. I heard that BURG was discontinued in 2010.

Zanna

03:15

I had to compile GRUB to get my first ever Ubuntu to boot :/

I knew nothing

fortunately someone had written perfect instructions

all the commands Just Worked

the hard part was getting to the point where I could run them by booting from the GRUB command line

WinEunuuchs2Unix

@Zanna Good for you compiling grub as a newbie :) My problems were compound because I downloaded normal.386 source but had EFI platform. I'd do it differently next time around.

Zanna

I had the instructions, but it took me a long time to figure out that I needed to swap some things there for my own root partition and kernel version, and what to enter, since I had only the vaguest idea what a partition or a kernel was haha

WinEunuuchs2Unix

just after I figured out what a partition was I read about LVM and HDD to SSD caching.... groans... back to square one on knowledge front :)

I guess it's similar to that old saying.... the more you know, the more you know you don't know.

Zanna

that one is true

WinEunuuchs2Unix

You don't post nearly as much as you used to Zanna. Still in India?

Zanna

03:25

It's sad that I don't post. Time issues, life issues

still in India :)

WinEunuuchs2Unix

Having a life is a good thing :). Remember rainy season for India is May like I said a month ago or so.

Zanna

It might rain, but I don't think it is the rainy season in May in this region

Government has declared drought also

Kulfy

@WinEunuuchs2Unix I'm an Indian. Basically here in North India rainy season is in mid of July when saavan (shravan) or say monsoon actually arrives.

We do have Shivratri too in that month.

WinEunuuchs2Unix

You are both lucky. Michael Bloomberg saved you :)

Zanna

that's bad

we need rain

@Kulfy Oh I thought it was in April. Does it vary by region, or does it come more than once per year?

WinEunuuchs2Unix

03:33

I think Iran stole all of India's rain a fortnight ago

Zanna

doubtless they needed it even more

WinEunuuchs2Unix

haha no they got flooded billions in damaged, plus sanctions from US they couldn't get goods into country

Zanna

:(

Kulfy

@Zanna It is celebrated 2 times in a year. One is Mahashivratri in Feb-Mar and one is Shivratri in Jul-Aug. They both have their significance.

WinEunuuchs2Unix

they have a beautiful country though with wonderful people and architecture, I'm sure Iran is doing OK. How do you do a right mouse click using keyboard?

Kulfy

03:38

For Saavan's Shivratri, read m.timesofindia.com/life-style/events/… and for Feb's Shivratri read en.m.wikipedia.org/wiki/Maha_Shivaratri

Zanna

Tomorrow cyclone Fani will pass close to us and perhaps bring no rain but higher temperatures (higher than 40 C)... then it seems she will hit eastern states and Bangladesh. I hope everyone will be ok :(

@Kulfy fast on Mondays to get a good husband :D

WinEunuuchs2Unix

There is another old saying "all the good ones are taken"

07:04

Hi, I VTC’ed askubuntu.com/q/1136284/250300 as a dupe of askubuntu.com/q/148638/250300 but later @Kulfy warned me I was wrong and I removed my close vote. Later the question was closed as a dupe with a correct target but the wrong one still appears in the targets, moreover as the first one. Could a mod edit it out (if it’s worth that work)?

Kulfy

07:25

@Melebius I think flagging the question for mod attention is a better option. They'll have a record and a mod who is away from chat but active on site can act on it.

Melebius

@Kulfy OK, I’ll do that.

Videonauth

09:22

@Zanna so what do we do with the island, now you re sending all the weirdos over?

sink it like atlantis west?

Zanna

09:38

@Videonauth just trying to keep them out of the boat

The island can be weird I suppose

Videonauth

ah, well a paddle over the head might be more eficcient :D

Zanna

It can just be the bin of the boat

I find it frustrating as RO that I can't just ban people from the room

Videonauth

okidoki, just asking because both lately moved people are not really understandable, i read their words but get no real meaning from it

Zanna

OTOH, maybe such excess power would cause many conflicts

@Videonauth yeah they are trolling or just dumping their thoughts

Videonauth

youre speaking of mod election?

Zanna

09:41

@Videonauth not at all

Just about room owner powers

Mods can't ban people from rooms either

Only suspend from all chat

Videonauth

oh ok, well I will for sure throw my hat in again this time. (speaking of the election)

oh ok good to know, no its fine to move them just asking

Zanna

I'm afraid I can only suggest ignoring the users if they bother you. Chat is hard to moderate

If the rooms were busy and everyone ignored disconnected messages, they might go away

Videonauth

--> youtube.com/watch?v=ee6-sI9rdtA <-- this i think of when talking bout Atlantis west (love monthy python)

Zanna

If we ignore them, they will probably go away even though the room is quiet

Videonauth

maybe

terdon

09:58

@Zanna You can kick them.

Videonauth

@terdon yep but this would not achieve what zanna wants, she wants a raiders channel to be clean of eprsonal chatter, this is what we made the island for if we come to talk to much to move messages over

terdon

@Videonauth Yeah, but if you have problematic users, you can kick them out of the room, right?

Videonauth

yes well they are not exactly problematic :), just weird, you can read for yourself in the island chat room :D

Zanna

10:34

@terdon for 30 seconds, no?

@Videonauth I don't mind personal chatter so much, but this kind of spaced out rubbish talking or trolling is bothersome

I would certainly like to ban them. But I don't think I can kick them for more than a short time out

I don't mind personal chatter at all - I move it to the island, purely so that those who check and follow up the moderation related messages can see them easily

That's not a bother for me to do

But now the island is turning into a dumpyard haha. That's also not a problem for me. But I would rather ban these users who are just thinking aloud about things I'd rather not know

Hello

Any apache gurus?

@Zanna Yeah, but it's a start. And you can also ask me to suspend them: being disruptive in a room is a good reason for suspension.

Or just flag with a custom mod flag, explaining that the user is disrupting the room.

TigerNuno

Anyone understands how apache access log works?

my apache log shows bots visiting multiple times each minute

doesnt have the name of a bot but must be a bot

I blocked that ip address on .htaccess

now the accesses seem lower looking at an observer tool

but they still keep showing up on apache log, it this normal? does the apache log entries every minute show they are trying to access the site but are blocked?

Zanna

11:41

@terdon thanks :) I will escalate if this person doesn't get bored soon

Videonauth

@Zanna well we could make the island and the downboat invitation only, and then give the people which frequents it permissions to write

Zanna

11:54

I want it to be open to all

Videonauth

12:05

Ok. was just a suggestion :)

@TigerNuno you always will have entries in apache access.log even if you have it .htaccess blocked, the server still has to process this and will generate a log, if you want it to cease completely you should use UFW or similar to reject incomming traffic from this bot/IP

but as long were talking about simple web crawlers,. the majority of em respects robot.txt file

Rinzwind

12:22

@TigerNuno block them at the router if you have access to that. Or at the ISP if they have such a service.

Videonauth

I use those scripts to handle bans on firewall level so my server generates no log anymore.

$ cat ../server/log/script/ufw-ban
#!/bin/bash
ufw insert 2 reject in from "$1"
ufw insert 2 reject out to "$1"
ufw status

$ cat ../server/log/script/ufw-unban
#!/bin/bash
ufw delete reject in from "$1"
ufw delete reject out to "$1"
ufw status

The fine detail on this way is that t bot trying to access does not even get an answer at all, and the server does not see it either.

Hello world.

@KazWolfe hello Kaz!

how are you?

Kaz Wolfe

Doing mostly ok. Remembered this chatroom existed so thought I'd pop in and say hi

Videonauth

do youu know you infected me with writing bot's :D

currently writing a chatbot for an discord server

Kaz Wolfe

lol thanks for reminding me

i need to go rewrite a good part of my bot. stupid logging.

Videonauth

@KazWolfe ask me i actually made 5 different bot versions over the past 5 months for one and the same purpose now i have to mush them all together in one sane file

so rewriting about 150 Kb of code which is completely undocumented :D

Kaz Wolfe

not bad

at least i've seen way worse

Videonauth

19:07

well it's enoug already to make me cry myself to sleep each night

hehehe

Seth

hello kaz

long time no see

@Zanna @terdon iirc successive kicks will increase the timeout to 5 minutes (and raise a mod flag), so you can get more than 30 seconds.

Long time since I've read the docs on that however so it might not be that way anymore.

I don't understand why artists release "live" albums. It's all the same songs..

Kaz Wolfe

to annoy people listening to an artist on spotify

"ugh another live song? skip!"

Seth

hahaha that is too accurate

Kaz Wolfe

19:14

... oh crap. i need to prepare lesson plans

meh tomorrow

Videonauth

@KazWolfe well o.k. that's a lot of code

Kaz Wolfe

super powerful platform though... oh, and antispam

Videonauth

although when the bot finally goes life its codebase including json files might quickly surpass that

Kaz Wolfe

those arent production json - just internal settings

i need to rewrite it in java at some point...

Videonauth

ah, ok well the settings file is small in my case but the bot is supposed to learn all entries on protondb.com

as it is supposed to be the chat bot for its discord

Kaz Wolfe

19:16

why learn instead of just query

Videonauth

well it will query but then learn from each query untill it has all the data, want to keep the traffic low

Kaz Wolfe

ah, i see - but wouldnt your cache eventually be out of date?

Videonauth

I not need to make a new request every time a game title is searched

well most of the cache will not change only the rating and thats a quick API query

which produces extra for the bot the current rating, trending, and best submitted report

this is the data which will always change

Kaz Wolfe

ah, i see

Videonauth

but game title steam link etc will not change

and especially steamdb.info are very nitpicky when bots access their site

even if it is for a non profit community project

Kaz Wolfe

19:20

database enginessss

on a very related note: Python ORMs are evil

Videonauth

ORM ?

Kaz Wolfe

basically instead of writing SQL you have the ORM do object <-> database mappings

Videonauth

oof no i will write json files depending on the speed of the SSD to fetch them fast enough

each steam title has a number so i will save steamid.json

but not sure yet if i go that route

the tricky and fun part was to make all the searches return something as people not searching for 'Life is Strange 2' thell typ e lis2 for example

abusing google search for that lol

Kaz Wolfe

yeah natural search is annoying

Videonauth

by the power of request and beautiful soup google solves that problem, implementing a search algo for that would be a pain in the ass

Kaz Wolfe

19:32

doesnt google have an api?

Videonauth

they have but you need to register and afaik pay for too. so i simply do requests for the web url

ducks

Question can you ignore single F numbers from flake8 via command line ?

speaking of F401: imported "x" but unused

@KazWolfe

Thomas Ward

19:52

@Videonauth with a tox.ini you can set up the flake rules

and which ones to not report on'

Videonauth

simply putting it into the base dire i run flake in ?

Thomas Ward

@Videonauth gitlab.com/teward/imaplibext/blob/master/tox.ini as an example for my one python project.

@Videonauth yes. You can see a travis and flake setup in that repo too

though travis happens by an autopush from GL to GH which triggers the travis calls :P

the actual tox config, etc. is still the same

Videonauth

ok that makes it easier, now i only need to find out how to make travis use python 3.7 or better to say which dist they provide to run 3.7 as their stadart is trusty and this knows no 3.7

Thomas Ward

yeah I don't think they can

you might have to go with circleci or something similar for 3.7

CircleCI and GL CI both have 3.7 but not Travis heh

(nor appveyor last i checked, which is Windows testing xD)

Videonauth

meh will google a bit, it strage that travis not supports 3.7 maybe checking with xenial as dist

hah

@ThomasWard using bionic as dist works and uses 3.7

dist: bionic
language: python

python:
  - "3.7"

install:
  - pip3 install -r requirements.txt --upgrade

script:
  - flake8 --config=tox.ini ./

Thomas Ward

20:06

nice

Videonauth

but it took a fair bit using this yaml file for the first time

Thomas Ward

i might update mine xD

their bionic should support 3.6 right?

Videonauth

travis-ci.org/Videonauth/ProtonDB-Bot/builds/526600999

bionic has 3.6.7 by default so i would say yes

seems it will use xenial anyways from what i can read from the log

Thomas Ward

heh

travis-ci.org/teward/imaplibext

worked xD

now i just have to Mock an IMAP setup xD

Kaz Wolfe

woof

Thomas Ward

20:13

Videonauth

@ThomasWard works with xenial already, it seems to have no bionic docker image so it resorts to xenial anyways

Thomas Ward

cool cool

either way :P

basically because of security, feature-bloat, and some really aggressive moves from bot developers.

also their anti-spam/raid/whatever detection is pretty sad.

poor features, poor code, poor performance. just an overall poor experience.

also because i really dislike having n+1 bots to do everything. i should only need one.

I agree. but that 1 takes time to make.

true, although diy's bot was made from pretty much day 1 so /shrug
