its a form of power to silence other devs and users |
| 00:00 |
Guest66334 |
not true at all |
| 00:00 |
Guest66334 |
if you release a license they have to respect it |
| 00:00 |
Guest66334 |
otherwise just don't use a license at all |
| 00:01 |
Wuzzy |
why do i have to respect it? |
| 00:01 |
Guest66334 |
because is the laws says that |
| 00:01 |
Wuzzy |
thats a terrible argument |
| 00:01 |
Guest66334 |
no is not |
| 00:02 |
Wuzzy |
My "talking to me" licence requires you to give me a nice paycheck, otherwise you violated the license terms. ;-) |
| 00:02 |
Guest66334 |
if i realease my job under a license i have the rights to claim a copyright issue on you and legally spacking if you lose the legal stuff you will pay lots of money |

the Law once stated its okay to kill jews. using the Law is a terrible argument |
| 00:05 |
Guest66334 |
no, that's wrong.. if you put something under license so you are able to claim right on it, but if you don't want the law will do nothing |
| 00:05 |
Guest66334 |
this is logic, if you don't want rights on something just don't use a license |
| 00:05 |
Wuzzy |
i am not arguing what copyright law does and does not say... |
| 00:06 |
Wuzzy |
i am arguing that copyright law is not a good idea in the first place |
| 00:07 |
Wuzzy |
lets say you draw an amazing picture. now what is the *only* way for me to share a photo of it online, legally? |

asking for permission |
| 00:08 |
Wuzzy |
exactly! |
| 00:08 |
Guest66334 |
or just let me put it under a license with redistribution |
| 00:08 |
Wuzzy |
you never have to give permission |
| 00:08 |
Wuzzy |
i could offer you a million bucks and you still dont give it to me |
| 00:09 |
Wuzzy |
thats my problem with this system |

yea but is my work, i'm not obligated to give my work to you |
| 00:09 |
Guest66334 |
it's just my rights to keep it for me |
| 00:09 |
Wuzzy |
you basically have a monopoly. also lets not forget that the copyright holder is not always the creator |
| 00:10 |
Wuzzy |
your "right" comes at the expense of everyone else's artistic freedom |
| 00:10 |
Hijiri |
Guest66334: if you don't do anything there is a default, very restrictive license that is applied |
| 00:10 |
Guest66334 |
sure ofcourse, developers inside big companies are not the copyright holders of the company's softwares |
| 00:11 |
Hijiri |
you have to explicitly license people additional permissions |
| 00:12 |
Guest66334 |
sure you can, but you just have to pick the right license, if you don't pick one at all i can do everything with your job |
| 00:12 |
pgimeno |
Wuzzy: now imagine it's a picture a friend made for profit and he's exhibiting it. You take a picture and distribute it. The picture becomes viral and it spreads and no one wants to buy it. That's bad for the creator of the picture: sharing it results in removing his source of income. |

i love how these discussions always quickly degrade about one thing |

Wuzzy |
MONEY |
| 00:12 |
Hijiri |
Guest66334: That depends on the specific relationship |
| 00:12 |
Wuzzy |
its so predictable |
| 00:12 |
pgimeno |
Wuzzy: yes, copyright is about money |
| 00:13 |
Guest66334 |
Wuzzy: that's how the world works |
| 00:13 |
Hijiri |
If I post something online with no explicit license, you get almost no rights |
| 00:13 |
Hijiri |
If I am your employee, you get all the rights |
| 00:13 |
Guest66334 |
again, we live in the real world, not in the ideal world |

Hijiri |
Guest66334: I'm talking about real law |

if your business model comes at the expense of the freedom of everyone else, it is worth to die |

yea ofc, if you post something without license i can do everything with it |
| 00:14 |
Hijiri |
I don't think people should be forced to send you anything, but the problems are when you prevent other people from sending the thing you sent them |
| 00:14 |
Guest66334 |
that's why a license is needed |
| 00:15 |
Wuzzy |
the money argument is missing the point |
| 00:15 |
Hijiri |
Guest66334: Did you even read what I said |
| 00:15 |

remember the million bucks? |

If I post something without license you can do almost nothing with it |

| 00:15 |
Guest66334 |
are you sure about that? |
| 00:15 |
Hijiri |
Yes |
| 00:15 |

Wuzzy: I beg to differ. Some people are best at creativity and suck at most everything else, and their best way to serve society and earn their living is to sell their creations. |

many people can't afford to be an artist. if you'Re not "useful" in this society, you're screwed |
| 00:16 |
Wuzzy |
but the question "how do i earn my living" is an entirely different beast |
| 00:17 |
Guest66334 |
well you may be right Hijiri but it depends from multiple |
| 00:17 |
Guest66334 |
like the platform where you publish something |
| 00:17 |
Hijiri |
depends from multiple what |
| 00:17 |
pgimeno |
my point is, without laws to protect their source of income, they would starve |
| 00:17 |
Wuzzy |
i guess fair use? |
| 00:17 |
Hijiri |
Guest66334: If you publish to a platform then usually the platform requires you to license the platform to redistribute it, in their terms of service |
| 00:17 |
Wuzzy |
thats why i am for basic income |
| 00:18 |
Hijiri |
Guest66334: But those rights don't extend to random viewers, usually |
| 00:18 |
Wuzzy |
it is very likely a ton of jobs will disappear. it already started. it will be harder and harder to make cash by working |
| 00:18 |

if this problem is not solved soon, things will get ugly |

well, I'm done with the off-topic excursion, sorry for letting myself being dragged into it :) |

if there's anyone here who's running an ubuntu system, I need to ask a favour.

this is Debian, but still. The 32 bit version says -2147483648 (=overflow); the 64 bit version gives the exact number entered. |

on ubuntu 16.04 *64-bit* I've had the owner of a server where this was causing problems report that it was clamped instead, namely 2147483647 |

that might depend even on how the Lua interpreter was compiled |

ii lua5.1 5.1.5-8.1+b2 amd64 Simple, extensible, embeddable programming language |
| 17:04 |

pgimeno: indeed, hence why I need data from other ubuntu users - they may have changed the comp flags in the meantime |
| 17:04 |
deltasquared |
apparently there is a compilation flag that affects it. hmm |
| 17:05 |
deltasquared |
I would have to look into the lua5.1 source code for starters. |
| 17:05 |
pgimeno |
$ dpkg -l lua5.1|grep ^ii |
| 17:05 |
pgimeno |
ii lua5.1 5.1.5-4 i386 Simple, extensible, embeddable programming language |
| 17:05 |
pgimeno |
^ the second one is the 32 bit machine obviously |
| 17:05 |
deltasquared |
right, so only the patch sequence number is different. I'll have to look at what they apply on top, if any |
| 17:06 |
pgimeno |
anyway, why not use "%s" instead of "%d"? |
| 17:06 |
deltasquared |
pgimeno: because it loses precision |
| 17:06 |
pgimeno |
it does what??? |
| 17:06 |
deltasquared |
for the above, using %s chops the last digit off |
| 17:06 |
pgimeno |
it's a float to start with |
| 17:06 |
deltasquared |
doubles actually, and they can fit a 48-bit int. |
| 17:08 |

ok, %.99g does it |

I think it was 17 for double round-tripping, so %.17g should suffice unless it starts to lose precision |
| 17:11 |
deltasquared |
pgimeno: hmm, interesting. so it does. seeing as it's basically the same as what C printf does... |
| 17:11 |
deltasquared |
hehe, "make it 99 so it can't possibly ever break!" |
| 17:11 |
pgimeno |
it *is* sprintf under the hood |
| 17:11 |
pgimeno |
that's why it doesn't take nulls (which is a shame) |
| 17:11 |
deltasquared |
probably why it's clamping also |
| 17:11 |
pgimeno |
yep |
| 17:12 |
deltasquared |
because it expects an int... which can be 32-bit |
| 17:12 |
deltasquared |
even on 64-bit machines |
| 17:15 |
pgimeno |
I thought 64 bit machines with 32 bit ints are rare. Maybe that Lua is the 32 bit version? |
| 17:18 |
sfan5 |
lua uses floats for numbers btw |
| 17:18 |
rubenwardy |
it uses doubles |

I literally just read that in the Lua source :) |

typedef lua_Number double; |
| 17:19 |
rubenwardy |
err |
| 17:19 |
rubenwardy |
other way around |
| 17:19 |
pgimeno |
sfan5: we're discussing string.format("%d", ...) which I am pretty sure uses sprintf under the hood |
| 17:19 |
sfan5 |
well close enough |
| 17:20 |
rubenwardy |
infact I believe that all Lua variables are 64bit, as it's a union |
| 17:20 |
rubenwardy |
*at least |
| 17:20 |
rubenwardy |
I vaguely recal |
| 17:20 |
deltasquared |
rubenwardy: it seems that it's sprintf's fault in this case either way |
| 17:20 |
sfan5 |
pgimeno: it indeed uses sprintf |
| 17:21 |
pgimeno |
the point here is, that "%d" applies to ints, hence it depends on the machine's word size independently of using the double number format |
| 17:22 |
deltasquared |
but at least on the sysV abi used by most unixen, int is always 32-bit |
| 17:22 |
deltasquared |
regardless of machine word size |
| 17:22 |
deltasquared |
if you're on x86_64, it's long that is 64 bits |

sorry about that, I was copying from screen to screen by hand :) |
| 17:38 |
deltasquared |
aaah, so it's long... which can *still* be 32-bit |
| 17:38 |
deltasquared |
I think it's only guaranteed to be 64 bits if it's ll |
| 17:38 |
deltasquared |
so in general, this was basically undefined behaviour |
| 17:38 |
pgimeno |
on a 64 bit machine? weird |
| 17:38 |
deltasquared |
pgimeno: I know, but still |
| 17:38 |
deltasquared |
that's what the C spec says |
| 17:39 |
deltasquared |
and undefined behaviour can eat your cat. :P (no, that last part is not in the standard, but it may as well be) |
| 17:42 |
pgimeno |
isn't it compiler-dependent as opposed to undefined? I'd guess Ubuntu would use gcc |
| 17:43 |

which is what still has me perplexed |

pgimeno: I dunno, all I can relay is the behaviour that was being seen - on a 64-bit ubuntu 16.04 system (the same one where the pipeworks bug was triggered), string.format("%d", 140881370316824) clamps to 2^31-1 (at least it isn't wrapping, but still annoying) |

I'm looking for VanessaE's servers in freenode (#ve-minetest-servers) but not even finding anything of hers with a "minetest" search. What's the new channel(s) or status? |

it should be on #freenode |

I read she shutdown InchraNet and moved under freenode's umbrella. |

Entering the channel name directly into the "Join Channel" did the trick but now I'm wondering (a fiddling with) why Hexchat's search won't pick it up. |
| 19:19 |

Heh. Now that I've added the channel to the auto-join list, it shows up on the search. (shrugs) |
| 19:20 |

traditionally channels set to secret won't appear in the channel list, but I don't know if that's the case with freenode |
| 19:20 |
pgimeno |
(mode +s) |
| 19:20 |
twoelk |
what does hexchat search? if it searches a local channel list you might have to refresh that |
| 19:21 |
LazyJ |
twoelk: There's a button to "Download" all the channels in the selected server. I hit that a few times. |
| 19:22 |
twoelk |
its a long list :-) might take it's time |
| 19:22 |
LazyJ |
pgimeno might be on to something as #ve-minetest-servers didn't come back as a search result until *after* joining the channel. |
| 19:22 |
pgimeno |
* Channel #ve-minetest-servers modes: +cnst |
| 19:22 |
pgimeno |
yes it has the +s flag |
| 19:23 |

that's typically done after spambot problems |

I'm trying to make a simple mapgen. I'm using minetest.get_mapgen_object("voxelmanip") inside register_on_generated, but I don't understand what the on_generated callback passes as min and max vs. the positions that get_mapgen_object returns. I am guessing that the positions returned by get_mapgen_object is the actual extent of the VoxelManip, but then what are the positions in the callback? |

so what are the positions passed to the on_generated callback? anyone? |

sofar |
minp, maxp |
| 22:25 |
sofar |
coordinates of the generated box (extremes) |
| 22:26 |
pgimeno |
sofar: thanks, but then what's returned by get_mapgen_object? I thought it was the same but it doesn't match |

'on generated' minp maxp is the volume of the mapchunk, but the mapgen object voxelmanip volume is the mapchunk plus a 1 mapblock thick (16 nodes) padding |
| 22:35 |
paramat |
a shell of mapblocks is always added what ever size the mapchunk is |
| 22:36 |
paramat |
pgimeno ^ |
| 22:38 |
pgimeno |
paramat: thanks, I see, so what should I modify? the whole VoxelManip or only the minp..maxp from on generated? |
| 22:40 |
pgimeno |
I'm guessing the latter? |
| 22:42 |
pgimeno |
I mean, I guess I should not touch that padding, right? |
| 22:54 |
paramat |
the padding is essential for trees |
| 22:55 |
paramat |
they need to extend up into the padding, otherwise you end up with large strips of terrain with no trees |
| 22:55 |
paramat |
but basically just alter inside minp to maxp |
| 22:55 |
pgimeno |
ok, thank you |
| 22:56 |
paramat |
and if you place a tree on the surface inside the mapchunk, allow it to extend up into the padding |
| 22:56 |
paramat |
so, trees cannot be higher than 16 nodes |
| 22:57 |
paramat |
in core mapgen, large caves and dungeons extend horizontally outwards into the padding, in the hope of overlapping other caves and dungeons, and to make these structures larger |
| 22:58 |
pgimeno |
what happens to what I write in the padding? is it lost? or is it merged with the existing content? |
| 22:59 |
paramat |
it's always preserved |
| 22:59 |
paramat |
mapgen will only overwrite "ignore" nodes |
| 23:00 |
paramat |
"ignore" == ungenerated world |
| 23:01 |
pgimeno |
hmm, I think the "ignore" part fills the gaps in my understanding |
| 23:01 |
pgimeno |
so, the initial value of the padding is either "ignore" or a previously generated area |
| 23:03 |
pgimeno |
if you write to the padding, whatever you leave as "ignore" will be overwritten by the mapgen |
| 23:03 |
pgimeno |
(that's what I understand from that) |
| 23:03 |
pgimeno |
and if you write to a previously existing area, the content you write replaces the existing content |
| 23:04 |
pgimeno |
if the above is right, now everything makes sense, thanks :) |
| 23:04 |
paramat |
mostly correct |
| 23:05 |
paramat |
actually, all correct |
| 23:05 |

sorry more context, i run a popular server, (C I T Y 2) and am interested in how much work will be involved moving to 0.5... |

will all current mods break? |

only player model related things |

very little breaks |

anything that does will be stated in the news subforum |

as they're our biggest assets |

0.5 is generally not breaking mods or worlds |
