WHEW.

Windows EXE installers are built. macOS DMG is built. PPA has been updated with new packages (which I published by hand). AUR updated to use latest version.

I don't have anything to do with Fedora, so I'll leave that to someone else.

I have announced the release to Twitter and Facebook.

Nathan Osman

Which reminds me - I need to alert all the people on G+. All two of them :P

jrg

nice work @NathanOsman

Nathan Osman

Thanks :D

jrg

IDK what you released but you released it

Nathan Osman

00:31

I'll be pulling the Android app out of beta soon as well.

@jrg NitroShare 0.3.4.

jrg

nice

Nathan Osman

Just mentioning this for fun but... I got an issue on GitHub today from someone asking if I could change the build system from CMake to qmake for a fairly large library.

Ah, here it is: github.com/nitroshare/qhttpengine/issues/19

Never mind that the task of replacing the build system for something that complicated would take days.

And without any explanation whatsoever for why it should be replaced.

AND qmake is eventually being deprecated.

Nathan Osman

00:50

Next challenge - I started working on the new version of NitroShare last year and I have nearly 100 commits to rebase on 100 diverging commits.

I will need to be creative.

jrg

Ah, merge conflicts.

Nathan Osman

I think I'll just delete everything and copy the files from the branch in.

jrg

and lose your history?!

Nathan Osman

Then I'll have one big commit that changes everything :P

Well, otherwise I have to rebase/rewrite 100 commits...

And that is not a thrilling prospect.

Nathan Osman

01:56

Oh I have totally forgotten about Hacktoberfest this year :|

I need to put in some pull requests.

@NathanOsman did you ever track down the weird Nitroshare Android bugs I reported to you?

Seth

02:34

@NathanOsman ugh, same.

Nathan Osman

03:16

@AndroidDev I think I got most of 'em.

And now. Time to flick the magic switch and enable the production build.

Drumroll...

@TheWanderer I am about to start receiving comments and ratings :P

The app was in beta up until this point and now it's out in the wild.

Nathan Osman

03:29

If anyone feels compelled to vote... news.ycombinator.com/newest (you'll know it when you see it)

:D

jrg

@NathanOsman don't link to hacker news items directly

it doesn't count those votes

same with reddit

Nathan Osman

It doesn't count which votes?

jrg

votes that come from sessions that land directly on the target vote

Nathan Osman

Ah.

jrg

so if i click that link and vote it doesn't count for the purposes of putting you on the homepage

Nathan Osman

03:34

That's pretty clever, actually.

jrg

you still get karma or whatever

Nathan Osman

Okay, I see.

jrg

but it doesn't put you on the homepage

Nathan Osman

I'll fix the link then.

Anyone know how to kill pcmanfm?

I keep sending it SIGKILL but it respawns.

I'm thinking LXDE is restarting it somewhere.

Apparently lxsession -r is not the answer.

However, it may be what I need for testing things.

Here's my first pull request (1/4): github.com/lxde/libfm/pull/32

danidee

@Seth it worked! (Compiling Postgres and copying the resulting binaries)...Thanks once again

@NathanOsman also on 1/4....Though it's a documentation pull request :-D not Actual code

Nathan Osman

06:25

@danidee No, I added about 10-15 lines of C.

It's a completely new feature.

Oh.

You are talking about yours :P

danidee

Yeah i know...i was talking about myself

Nathan Osman

Sorry, I misunderstood what you said :P

Documentation is important too, don't feel bad.

In fact, I would even venture to say, it's just as important as good code.

danidee

Yeah especially documentation in the code itself.

I'm not a big fan of "The code should be clear enough not to need comments"

It's really important to know Why something was done....and only documentation (When the author isn't around) can tell you that.

Nathan Osman

Examples are also quite useful as a form of documentation since they show you how to use the code to solve a problem.

07:28

Maybe I'm just blind, but is there really no thoroughly answered question about bash script options yet, not even on U&L (the best I could find is this?

Something that explains the differences of GNU-style short and long options (-o, --option) and possibly also XF86-style long options (-option) and presents the different ways of using them yourself with getopt, getopts, while :; do case, select opt in "${options[@]}" and whatnot, including ups and downs. I don't believe Stephane Chazelas didn't take this challenge yet.

Stefano Palazzo

@jrg whatup :)

Stefano Palazzo

@NathanOsman I just tried out the android app, and it's amazing. the user experience is really nice!

@NathanOsman there's one thing that's kinda weird. When I'm browsing files and I want to go up one directory, I hit the back arrow button in the top navbar and that sends me back to the main activity, not the previous directory.

I don't think the button should send you up one directory, but maybe it shouldn't be there at all (like in the Downloads app)

By the way @dessert, for future reference, here's a meta thread you can link to when asking people not to post images of their terminals: meta.askubuntu.com/q/8713/85695

Just to show that this isn't some rule you're making up but has been discussed.

nathdwek

Hello how do I make it so that the global sound volume also applies to notification volume?

Rinzwind

Gundam IRL :D

@nathdwek eh. it doesn't by default? :=P

that's not very "global" then

nathdwek

09:29

well I am a bit dumbfounded myself

I have the "output" volume which is controlled by my keyboard shortcuts and the UI slider

but the "sound effect" volume is totally independent from that

I do not recall this behaviour previously

Its annoying for me because I often change the volume depending on the environmental noise, the type of headphones I have etc, but then either notification will blast my head off, or I will miss them

@Rinzwind ?

terdon

That's odd. Ask a question on the main site and be sure to show us screenshots of your sound settings.

what is swap area ??

terdon

Virtual memory

In computing, virtual memory is a memory management technique that is implemented using both hardware and software. It maps memory addresses used by a program, called virtual addresses, into physical addresses in computer memory. Main storage, as seen by a process or task, appears as a contiguous address space or collection of contiguous segments. The operating system manages virtual address spaces and the assignment of real memory to virtual memory. Address translation hardware in the CPU, often referred to as a memory management unit or MMU, automatically translates virtual addresses to physical...

terdon

Essentially, you can think of it as a part of your hard drive that is being used as though it were RAM @AjayMistry

Journeyman Geek

@AjayMistry also, if you need to ask, go with the defaults and don't touch it ._.

iliya

And what is the normal size for allocating this swap area?

terdon

10:30

There's no normal. It depends on your setup.

Journeyman Geek

@iliya rule of thumb is "whatever makes sense"

terdon

How much ram do you have and how much disk space?

iliya

ah, exactly what i wanted to say

8GB

1TB

Journeyman Geek

I have a system with 8gb of ram, and a 32 gb hdd, (second boot) and the old "2x ram for swap" makes no sense

terdon

You still need at least $sizeOfRam + 1 or so for hibernation right?

Journeyman Geek

10:33

+1?

terdon

N

Journeyman Geek

I suppose bigger makes sense.

terdon

A bit more than your ram, to be on the safe side

Journeyman Geek

In this day and age though, there's no real downside to a swap file over a swap partition tho

terdon

Although, on my system I have 32G of ram so that isn't really reasonable either. I've set up a 14G swap partition for my 32G of ram.

Journeyman Geek

10:34

which renders that question slightly moot if you're a poweruser

iliya

so for this example 9 GB is the right choice. is it?

terdon

@iliya Or 8, really. Or 8.1 or whatever. It isn't a very important thing anymore.

Journeyman Geek

@iliya or 8.5 gb. But once again, there's a good chance you're basically wasting space.

terdon

@JourneymanGeek Well no. 8G RAM is very likely to get used up if you have a few tabs open. So you still need some swap. It doesn't need to be a full 8G of it, but a few G to make sure your system doesnt' run out of memory too often is a good idea. And since Ilya has 1T, he can spare 8G of it for swap

iliya

@JourneymanGeek Is there anyway to monitor this area?

terdon

10:40

Monitor?

You can see its usage with tools like free and top

iliya

maybe it can clear up how much is enough

@AndroidDev which is all you need - right ? :)

@AndroidDev the price looks good for what you get :)
