To this day, I will never know how I managed to get 659 rep. on Math.SE.

Here are the first three questions when I load the home page:
- Prove that S(m,n)S(m,n) is true for all m≥1m≥1 and n≥1n≥1.
- A Dugundji problem about the continuity of distance
- minimizing eigenvalue of a product of matrices

I have no idea what the heck any of that is :P

Thomas Ward

well i'm officially annoyed this evening.

and my day was going so well...

TheXed

@ThomasWard oh?

Thomas Ward

@TheXed basically? I was trying to add my business's radio configuration infromation to the radioreference.com database, and was implicitly accused of submitting false data and lying about having an operational business.

In the public forum section of their site.

There's only a certain level of unprofessionalism I will tolerate, but publicly implying that I'm submitting false data or lying about the business which I own/operate goes beyond that level of tolerance.

grumbles

i wonder if there's anything I can burn on the flags queue...

TheXed

@ThomasWard sue them for racial profiling or something...

Thomas Ward

@TheXed i could sue them for slander but it's not worth my time to go after a company because of a single individual who said it. The nice little rant post and response I wrote on their forums while borderline against the rules does justice to show that I'm not a fan of the level of unprofessionalism I was shown by that one individual, and that their actions detract from my overall opinion of their group now.

pretty sure when their CEO and other mods look at that they're going to be a bit annoyed

(it's an LLC after all that runs that site)

I technically have a case against them. Not worth my time to sue them.

TheXed

2:39 AM

I am an American so I say SUE them anyways!

2

I mean I say that because as Americans aren't we obligated to sue everyone for every little mis-step they may take?

Thomas Ward

Publicly ousting them and stating that it shows the entire hired staff might be able to act in an unprofessional manner publicly on the same forum thread as where they implicitly were accusatory to me is equally effective.

besides, as long as my business continues to have partners and contracts with other companies and individuals, I'm happy.

TheXed

Can I sue you for not suing them?

Thomas Ward

@TheXed Can you afford risking going up against the 12 lawyers I have on retainer as my defense team if you do?

TheXed

Johnny Cochran is all I need to afford...which I can't so I guess the answer to your question is no.

Oh wait he is dead anyways...So I guess I won't be suing you.

Thomas Ward

@JourneymanGeek i've got pickled ginger in a jar, actual pickles, and 12 bottles of Angry Orchard hard apple cider in varying flavors in my fridge currently.

@Videonauth Thanks! Didn't think about that. =)

I do think it is answerable as it looks like OP just needed to add the ppa:kubuntu-ppa/backports to get all the dependencies installed.

@CharlesGreen missing fireftp, missing flashgot, missing flashblock, missing noscript, missing password exporter (which is not possible to update to 57 because they have not finished the api for that already), missing password editor,

testing 57 in a vm tho

i put this package on hold on my bare metal installation about 2 days ago

and someone asked on Ask Ubuntu about how to downgrade

@ByteCommander are you sure about that? what you just commented?

ok testing right now

Nathan Osman

@Videonauth I think 400 samples at 1080p. It was rendered on a Mac Mini with an i5 so that's not too surprising.

Videonauth

@NathanOsman oh ok well 400 samples is not really much

Nathan Osman

I know :P

You can see a lot of noise if you look closely.

But I'm still waiting for amdgpu pro to come to Arch so I can get OpenCL support for my GPU.

Videonauth

yep saw it, you can get rid of the noise when you put refraction clipping to 1

this will kill out most of the noise

this here was done with 2048 samples at 1080 p and took about an hour to render a single image

@ByteCommander are you here?

Nathan Osman

6:53 PM

Nice!

@Videonauth where is the refraction clipping option?

Videonauth

sec

@NathanOsman if you use the cycles render engine it is under sampling named "clamp in" if youre not sure you can set both to 1 which will for sure remove all fireflies in 99.9999% of all cases

Does it appear in your apt policy firefox?

I don't want to un/re/install anything right now

But I strongly believe that apt policy doesn't lie on me and if something isn't there, it isn't there.

Also see packages.ubuntu.com/search?keywords=firefox - Xenial only has 57, Artful has both 57 and 56.

You only have 56 on artful, because that was the version it got initially released with, I think. Xenial got released with 45.

That will take it from cache.

well, it would if it wasn't already installed...

in worst case i can reset the VM

Byte Commander

If you desire so...

but 45 could be installed

@ByteCommander you can remove your comments, i included my findings now in my answer

Byte Commander

I see no need to do that?

Hmmm... okay, actually I thought I had worded it a bit differently. As it is, it indeed doesn't really fit well any more.

@NathanOsman the headphone i showed up to took 20Gb swap, 8 GB ram and put my GPU under full memory load as well which has 4 GB ram

Downvote for arbitrarily running sudo apt dist-upgrade. It's very likely that the user does not want to automatically upgrade all their other packages in the process of downgrading Firefox. — Micheal Johnson 3 mins ago

8:28 PM

ok can anyone tell me what still wrong with my answer there? now accumulated already 2 down-votes, even if it addresses the most what was asked in the question, which was asking for downgrade from 57 to 56 and not how to install 52 ESR and so on

:(

Charles Green

Maybe they're just convinced you should not downgrade

You're standing against the winds of progress

Luddite

Videonauth

well i did put my firefox on hold a few days ago, its not touching me, but the question was how can i downgrade from 57 to 56

and it is a technical perfect answer, tested every command in a VM even

one downvote for suggesting toing an update on the system files, which seems to be a bad thing in the linux world and one for whatever reason

Charles Green

I had read in the past, that sometimes dist-upgrade occasionally does stuff you don't want to happen. Since I'm always running VM's and keeping them absolutely up to date, I'm rarely surprised.

Videonauth

well here too, sudo apt update and apt dist-upgrade is running here as a cron job :) 1 time per day

i had it once due to a packaging failure on nvidia drivers that my system would do a login loop, but thats it.

Rinzy :)

how was your day?

Byte Commander

8:45 PM

actually apt upgrade is everything you need

apt-get dist-upgrade was necessary because apt-get upgrade only upgraded installed packages and skipped those which needed new packages to be installed, like kernel updates.

but apt upgrade allows that by default

Videonauth

well i took that out now if its for other users so disturbing to updade their system

Byte Commander

apt full-upgrade allows it to also remove packages if that is necessary to upgrade something, which I would never recommend to blindly run.

grooveplex

how do I earn reputation now that edits don't give me any anymore?

Byte Commander

Not sure what exactly dist-upgrade is for in case of apt, maybe it's just an alias of apt-upgrade now (or apt full-upgrade, which would be bat IMO)

@grooveplex ask. answer. simple.

Videonauth

apt dist-upgrade does in fact simple apt-get dist-upgrade afaik

i never got upgraded to a new version of ubuntu or such using it

dist-upgrade
           dist-upgrade in addition to performing the function of upgrade, also intelligently handles changing dependencies with new versions of packages; apt-get has a "smart" conflict
           resolution system, and it will attempt to upgrade the most important packages at the expense of less important ones if necessary. The dist-upgrade command may therefore
           remove some packages. The /etc/apt/sources.list file contains a list of locations from which to retrieve desired package files. See also apt_preferences(5) for a mechanism

grooveplex

8:50 PM

also, Firefox 57 is soooo fast.

Byte Commander

9:04 PM

I don't want to enjoy that yet until most of my add-ons are compatible

After all, I don't use FF because of its performance but its customizability.

Videonauth

^this here too

the list of add-ons i would have to leave back is actually to high for me, and some even wont be able to update until they add some parts of the API in FF58

if that parts of API make it in that release

i tried to find replacements for the add.ons yesterday and found only password managers who want to upload to some cloud etc for storage and so on speaking of those two add-ons i really would miss the most --> addons.mozilla.org/en-US/firefox/addon/saved-password-editor and addons.mozilla.org/en-US/firefox/addon/password-exporter

and FF 57 has no API for them to work on
