@Slereah fyi re "results," had another thought on that, ran across this recently, liked it a lot, maybe some interest to mathematicians/ number theorists/ math physicists in here. cellular automata proven equivalent to the collatz conjecture :) Cellular Automata to More Efficiently Compute the Collatz Map / Chen arxiv.org/abs/1301.3125

5:00 AM

HEY guys I have posted a new question

HEY where is John Rennei

Bernardo Meurer

@Akash.B Don't.

Don't?

What I did?

Bernardo Meurer

Ping people when you ask a question

They'll answer if they want to

Don't bother them randomly

Dawood ibn Kareem

5:31 AM

@BernardoMeurer Actually, Dr Rennie says in his profile "Just ping me if you want my attention". It seems unreasonable to tell someone not to, when Dr Rennie has given his explicit permission.

rekt

Bernardo Meurer

@DawoodibnKareem Did you see the guy's question?

And also, where in his profile does it say that?

Dawood ibn Kareem

No, I didn't see Akash's question. And the part that I quoted is the last sentence of the "autobiography" section of Dr Rennie's profile.

@Akash.B it's fine to ping me, though given I've only just woken up I may not be as lively as usual :-)

Dawood ibn Kareem

I've just read the question in question. John should probably go back to sleep!

@JohnRennie you are much braver than I am to issue such an open invitation. I would by no means invite the Stack Overflow community to "ping me with any Java questions".

5:37 AM

I only said it was fine to ping me. I didn't say I would respond :-)

Dawood ibn Kareem

@JohnRennie I feel sad when I see people coming here, and refusing to direct their questions to anyone other than you. Not just because it's kind of insulting to everyone else in the room. But it also seems that you have made your own monkey for your own back. Or whatever the appropriate English expression is.

but john is the monkey

Bernardo Meurer

@0celo7 Did you read my paper?

Balarka gave it a Strong 9

Oooooooooh my question is duplicate again

the logic one? of course not

Bernardo Meurer

5:42 AM

@0celo7 Why not??

I don't read logic

Bernardo Meurer

It's not logic even

set theory, same thing

Bernardo Meurer

@0celo7 It's not set theory either?

It's graph theory, and complexity theory

and some theory of language

set theory!

Bernardo Meurer

5:45 AM

THERE IS NO SET THEORY IN THOSE

fine, I'll read it if my legs feel better tomorrow

Dawood ibn Kareem

@Akash.B The fact that 75% of the questions that you've asked on this site have been closed as duplicates suggests to me that you should probably work on your search skills before you post again.

Bernardo Meurer

What's with your legs?

they're pretty bad from skiing

Bernardo Meurer

I'll email you a higher-res version

Skiing? In Virginia?

5:48 AM

west va

I can barely walk now they're so sore

this means I can't easily jump off a roof after reading your thing

It's more like this, as you continue to read to page 12, sure, there is no upper limit to signal propagation speed, but the lorentz transformation only admits one speed that is invariant, meaning that there is only one signal speed which all reference frames will agree on how fast the signal is propagating. When signals that are faster than this invariant speed is introduced, if timelike events based on the invariant speed is involved,
then these faster signals will lead to causality to be inverted, which then lead to time travel paradoxes

> The inversion of the time ordering for two events connected by the propagation of
a tachyon is therefore not, by itself, a difficulty. However, unless some restriction is
imposed on the type of propagation, it is potentially a source of paradoxes, as it can lead to situations where two events are timelike related, and yet the cause follows the effect. A typical argument is the following, sometimes picturesquely referred to as the “tachyonic anti-telephone”

@BernardoMeurer are there sets in this thing

Dawood ibn Kareem

@Secret Can I patent that?

Bernardo Meurer

@0celo7 No sets

@DawoodibnKareem nope, its already copyrighted, it's taken straight from that article

Dawood ibn Kareem

5:53 AM

@Secret Damn! I suppose the problem with an anti-telephone is that it would be seem weird if you start thinking about somebody just after they call you.

no, the time ordering will actually be reversed in at least one frame due to the invariant signal speed, thus cause and effect swithc around in one frame while remains ok in another, thus you staged yourself to create a grandfather paradox

Bernardo Meurer

@Pandya A Trisquel user?

so its not weird but harmless

Bernardo Meurer

You're a pretty rare pokemon

@Akash.B new to the chat room? visit faq to get familiar :)

@BernardoMeurer Yes.

5:55 AM

Q: https://physics.stackexchange.com/questions/393965/thought-experiment-what-will-be-the-result
Why is this "offtopic"?

Bernardo Meurer

@Pandya Nice, congratulations on your effort! How is HW support?

@BernardoMeurer Actually I started to use Trisquel 7.0 LTS on my Desktop PC in the end of 2014.

Dawood ibn Kareem

@user626528 because it doesn't fit the policy on homework questions. The comment under the question, attributed to David Z, was very clear.

And Recently 8 month ago I purchased a Dell Laptop in which I've Ubuntu GNOME 16.04 LTS. Not tried Trisquel yet on Laptop.

Dawood ibn Kareem

"Homework-like questions should ask about a specific physics concept and show some effort to work through the problem. We want our questions to be useful to the broader community, and to future users"

5:58 AM

@Dawood ibn Karee, it has absolutely nothing to do with any homeworks.

Bernardo Meurer

@Pandya I run Arch, so I'm interested in Parabola, ofc

But I've been worried about HW support

Hardware support is fine but I can't say much regarding Wifi, Bluetooth and Battery since my Desktop PC deosn't have such hardware and not tried Trisquel on Laptop @BernardoMeurer

Dawood ibn Kareem

@user626528 And that's why the comment specified "homework-like questions". It certainly resembles the kind of question one might find in one's homework.

Bernardo Meurer

@Pandya Well, things other than WiFi, Bluetooth, and Battery have never been the issue :P

But alright, thanks :)

@BernardoMeurer Yes, I want to implement Trisquel 8 on my Laptop but the development delayed (not released yet)

Bernardo Meurer

6:01 AM

Maybe when it's out it'll have a GNU Hurd option :P

I can't help but mock Hurd

@DawoodibnKareem it has nothing to do with any homeworks. I'm just trying to figure out the concepts of relativity better.

@BernardoMeurer So, do you support GNU/FSF/RMS ?

Bernardo Meurer

@Pandya Yep

@BernardoMeurer Once I wanted to try Debian with Hurd but not get enough time!

Bernardo Meurer

Don't, I've tried Hurd and it's a POS

6:02 AM

@BernardoMeurer Very Nice!

Bernardo Meurer

Well, mostly I'm a fan of the GPL

All my SW is GPL licensed, except for some libraries that are Apache or MIT/X11

Dawood ibn Kareem

@user626528 I don't have the power to re-instate your question, so arguing with me about this is pointless. I'm just trying to explain David Z's decision. Your question resembles homework, whether it's actually homework or not. Therefore, for it to be welcome here, you need to show some effort to work through the problem. That's the rule.

@BernardoMeurer Two year ago I written one blog on my computing which is outdated now though

Bernardo Meurer

Tbh I don't have any problems using only Free software

@DawoodibnKareem I've constructed this thought experiment. Don't really understand why it's "not enough effort".

6:05 AM

@BernardoMeurer Congratulations! Btw, are you a developer?

Bernardo Meurer

@Pandya Yep

And a student

I really like the ethics of Software Freedom preached by RMS!

Bernardo Meurer

Well, he goes overboard sometimes

But I mostly like his work, and try to do my part :)

Dawood ibn Kareem

@user626528 Well, you could ping David Z and ask him what he was thinking. I've found him very approachable, intelligent and easy to reason with. However, my thought on this is that now that you've formulated your thought experiment, it would be good if you could work through what you think the answer might be, and include the analysis with your question.

You may be aware that in the starting of 2015, he declared that he started to run Trisquel!

Bernardo Meurer

6:09 AM

@Pandya Well, I'm not, I don't follow him that closely I guess

@DawoodibnKareem sorry, but all these new requirements don't make any sense to me. If I could answer this question, I wouldn't need to ask in the first place.

Bernardo Meurer

I also don't like Debian, nor Debian-derivative distros

Just not for me

@BernardoMeurer ok. I also don't but I like the philosophy of GNU.

Bernardo Meurer

I run Arch on my PC, and OpenBSD on my servers

@Pandya What does liking GNU has to do with RMS having switched to Trisquel?

@BernardoMeurer Actually I started using GNU/Linux by Ubuntu so, I'm familar with Debain packaging and that's why I am using Trisquel.

Dawood ibn Kareem

6:11 AM

@user626528 I see what you're saying, and I don't know what to add to what I've already said, and to what's already explained in the "help center". @DavidZ would you care to weigh in?

Be aware that it's 11:10pm where David Z lives, so he probably won't respond right now.

Does Perabola works fine? @BernardoMeurer

Bernardo Meurer

@Pandya Yeah, I started on Ubuntu as well, but I left quickly because I don't like apt

Parabola works well, yeah

I've ran it on a server for a while

Read my profile how I started and left Ubuntu. And some about switch to Trisquel

May claim was about non-free repo

Bernardo Meurer

I understand all of that, it's the same reason I've been considering Parabola, to avoid non-free blob

@BernardoMeurer Can I know why don't you like apt? actually I don't know much about various packaging systems like rpm and others

6:17 AM

(Room is currently in CS mode, hmm...)

@Secret CS ?

computer science?

\o/

@0celo7 Ook ook

> The image of space being bent is just an analogy, it is not meant that anything is actually being deformed. Gravity distorts the notion of distance on spacetime, i.e. the presence of matter somehow causes the metric to change. A way to visualize this is to think of spacetime being bent, as you say, but really, spacetime is not made of anything, the idea of an ether has been laid to rest for a hundred years now, with good experimental reasons.

Recently I am toying with a scifi idea based on this

Consider a region of space where there's a particle

Bernardo Meurer

6:20 AM

@Pandya For starters I don't like that they felt they needed a format for the packages. There's no reason packages shouldn't be a tarball and that's that. Secondly, the pkg manager includes the --autoremove flag, which is basically a "Please help me nuke my system without knowing how to fix it". Lastly I find it way too verbose and slow

@BernardoMeurer Btw, (as the stuff are off-topic here) we can discuss on /dev/chat for further discussion regarding comparison of various package management and distors or have a personal chat-room.

CS is not off topic in h bar

Bernardo Meurer

@Pandya We can talk about it here, often times we talk CS in here :)

h bar has many modes

e.g. food, CS, chemistry, philosophy, mathematics, politics, memes etc.

@BernardoMeurer ok :)

6:22 AM

(cont.) The space in question has an extra structure called a Probability Field.

The particle is classical, meaning that it has a well defined trajectory

Now consider the following diagram depicting the particle passing through that region of space:

@BernardoMeurer you mean one should learn to compile and install from source rather then readymade deb or so?

Anonymous

@Secret I like it that you didn't mention physics :P

Bernardo Meurer

@Pandya No, I do not think that. In general I don't like source-based distros, although I have used Gentoo.

I think a binary pkg should be a tarball that you untar at / and it works

Btw, Has this room celebrated R.I.P of Stephen Hawking?

Bernardo Meurer

It should not need specialized formats, or anything of the kind

a package should just be a .tar.gz

6:24 AM

@Blue lol, I have a habit of not including the default mode of a room in my analysis, because it is self explanatory

@Pandya See the 21 starred message

Anonymous

@Pandya Is that something to celebrate? :)

@Blue sorry my poor English vocabulary. choice

@Secret The default mode of this room is memes and food. Not physics :)

My laptop has a small screen. Even it doesn't show more than 4 messages

@Secret I never on mac (even not in dream!) \o/ I am using somewhat enlarged screen

(cont.) Now since there's a probability field $\Bbb{R}^3 \mapsto [0,1]$ an observer near the travelling particle will see something very weird:

Bernardo Meurer

6:29 AM

@dmckee I need help with the POSIX shell spec

@Pandya well you have found it, so it does not matter

@BernardoMeurer what is the difference between source-based and a binary?

Anonymous

Any idea how long private beta sites take to transition to public beta? (On average)

Bernardo Meurer

@Pandya In a source-based distro you have to compile all the packages yourself, which takes time but gives you greater control of how you'd like your programs to be configured and compiled

(cont.) The particle will pop in and out of existence as it travels along its trajectory, thus look like a sequence of blinks in a certain direction. In fact, if you repeat the experiment, the particle can blink in and out of existence in different places, showing its statistical nature

6:31 AM

@BernardoMeurer As I'm not a developer, nor my education/profession belongs to computer/software in general I don't know in much depth. So, I usually wanted to learn more.

Bernardo Meurer

in a binary distro you download pre-compiled programs, which makes your life easier, take less time, but are less optimized and finely tuned to your needs

Dawood ibn Kareem

Feb 27 at 21:01, by Jake Rose

Apparently stephen hawking roams around here but ive only ever seen him once

Bernardo Meurer

90% of people are fine with a binary distro

@Blue which community?

Anonymous

@Pandya The Quantum Computing community is around 5 days old

6:32 AM

@BernardoMeurer Is't deb a pre-compiled?

Anonymous

I was wondering when it will go public so that I can tell people about it

(cont.) Now, if you have a large enough ensemble of particles moving in that trajectory, then you will start seeing a long snake of particles materialised as the ensemble average

Anonymous

It still doesn't appear in google search

Bernardo Meurer

@Pandya Yes, it is

So are Arch/Parabola's pkgs

@BernardoMeurer and that is same as binary?

Bernardo Meurer

6:33 AM

The only source distro that is large is Gentoo, and then there's Void but nobody uses that

@Pandya A binary is the result of compiling a source

So yes

ok. Thanks

Bernardo Meurer

Look, most of my points of disliking Debian are really technical and small, you're probably better off not trying to move away from something that works well for you

Q: What is Binary package? How to build them?

I want to get detail about binary package and run them on linux. I am running Debian base (Ubuntu/Linux mint) Linux os. How to build binary package from source? And can I directly download binary package for applications (like firefox, etc.) and games (like boswars, etc.) ? I run some direct pa...

package-management compiling binary packaging deb

^^ I still don't remember the answer.

@BernardoMeurer "For starters I don't like that they felt they needed a format for the packages. There's no reason packages shouldn't be a tarball and that's that" I didn't get can you explain? do you mean package should be in .tar instead of .deb ?

Smoke weed everyday

How's it going everyone

Anonymous

dab^{-1}

Bernardo Meurer

6:38 AM

@Pandya Kind of. As I said, these are pretty technical points. Mostly my point is that a pkg should be a simple tarball that conforms to the Linux FHS standard, so you can easily install the pkg without a pkg manager if you need. Moreover it keeps things simple

If you don't know what the Linux FHS is, google it, and read on it. It's the standard for how files are organized on a Linux filesystem

@BalarkaSen This is pretty good

Derecho de Nacimiento (En Mano de Los Macorinos) (Cover Audio)

Also, @BalarkaSen, @0celo7 Doesn't want to read my essay :(

Basically what I look while choosing the distro: 1. Does it respect software freedom (GNU/Linux)? 2. Package Manager and 3. Desktop-Environment.

@BernardoMeurer yes, I know file system Hierarchy Standard :)

Bernardo Meurer

@Pandya Again, it seems like we have pretty different needs

1. and 3. don't even matter for me

and 2. is important

:)

@BernardoMeurer ok. So, how Arch/parabola deal with it?

Bernardo Meurer

@JohnRennie The world of C development just got a lot better

@Pandya In Arch a package is a gunzip tarball that is unpacked at / and it just works :)

@BernardoMeurer And I really have lake of knowledge in that (2. Package Manager) area :(

@BernardoMeurer cool!

Bernardo Meurer

6:44 AM

But again

If Trisquel works for you, stick with it

Arch is a bit harder to manage if you don't have technical knowledge

But

It does teach you a lot

@BernardoMeurer And can you give some example of popular distro emphasizes on tarball pack type package management?

RedHat, SuSE, Fedora etc...

Bernardo Meurer

I don't know, honestly, I have never used any of those

I know Gentoo and Void work similarly :)

"Arch is a bit harder to manage if you don't have technical knowledge But It does teach you a lot" I really like that :)

Obviously smart work needs the knowledge!

At present you use Arch and Perabola, right?

Bernardo Meurer

@Pandya If you have time, I recommend trying it out. Feel free to drop by and ping me for help if you need it

I use Arch

And it's Parabola

I have Parabola on a server

But just for fun

Btw, Leaving the Debain would be somewhat difficult for me since I am only familiar with apt and dpkg!

Bernardo Meurer

6:49 AM

@Pandya It's only hard for the first few weeks

then you get the hang of it

But later or sooner I really want to migrate to the distro that follow standards, having compatibility, respect the freedom and stay active in development.

Btw, @BernardoMeurer do you know about Guix SD which is developed by GNU itself? (Guix Package Manager)

gnu.org/software/guix

Bernardo Meurer

Yep

I've heard of it

@BernardoMeurer decades ago I used to code in Algol 68, and it produced some of the most bizarre compilation error messages I have ever seen.

Do you feel the Linux vs GNU/Linux vs Lignux controversy interesting? @BernardoMeurer

Among the popular distros I found only Debain call them GNU/Linux

Bernardo Meurer

@Pandya Nope, I'm more interested in Kim Kardashian than I am in Lignux

6:56 AM

@BernardoMeurer ok. I'll think for that :)

Bernardo Meurer

Also if they rebranded to lignux I'd switch to BSD

@JohnRennie Lol, that sounds pretty horrible

Honestly GCC's error messages are a language in and of itself

That I learned throughout painful years

@BernardoMeurer what is "Kim Kardashian" ?

Bernardo Meurer

@Pandya If you don't know it, DO NOT GOOGLE IT

It's a pretty useless human being

user image

Bernardo Meurer

My point is, I think lignux is pretty stupid and petty

6:58 AM

@BernardoMeurer \o/

It's flippin' snowing AGAIN!!

Bernardo Meurer

@JohnRennie Take a selfie doing a snow angel for us!

@BernardoMeurer Yes, but GNU/Linux is deliverable I think

Bernardo Meurer

Or write "PSE ROCKS" in the snow with pee

@Pandya It's a mouthful

Everyone says Linux, that won't change

@BernardoMeurer No chance. It's warm and dry indoors :-)

Bernardo Meurer

7:00 AM

I’d just like to interject for moment. What you’re refering to as Linux, is in fact, GNU/Linux, or as I’ve recently taken to calling it, GNU plus Linux. Linux is not an operating system unto itself, but rather another free component of a fully functioning GNU system made useful by the GNUcorelibs, shell utilities and vital system components comprising a full OS as defined by POSIX.

Many computer users run a modified version of the GNU system every day, without realizing it. Through a peculiar turn of events, the version of GNU which is widely used today is often called Linux, and many of i…

blablabla

@JohnRennie One of the few times "warm and dry inside" is meant as a compliment ;)

@BernardoMeurer fnarr, fnarr :-)

Bernardo Meurer

Hehehe

I have a dead server this morning. And the VPN to the site router keeps dropping so I can't get onto the DRAC to see what's wrong. That's a pain.

Bernardo Meurer

@JohnRennie The hell's a DRAC

Hardware control card

7:02 AM

@BernardoMeurer so, do you support why to call GNU/Linux or not? what is in name?

The Dell Remote Access Controller or DRAC is an out-of-band management platform on certain Dell servers. The platform may be provided on a separate expansion card, or integrated into the main board; when integrated, the platform is referred to as iDRAC. It uses mostly separate resources to the main server resources, and provides a browser-based or command-line interface (or both) for managing and monitoring the server hardware. == Features == The controller has its own processor, memory, network connection, and access to the system bus. Key features include power management, virtual media access...

Bernardo Meurer

Ah

Malware

It's a lifesaver. Trust me on this one.

How can it be malware? It doesn't have an OS.

Bernardo Meurer

@Pandya I think it would be nice, yeah. I also think it won't happen, it's a pointless fight, and people should stop worrying about it and just drop it ffs

Well ... I suppose it has some form of basic operating system

Bernardo Meurer

7:03 AM

@JohnRennie I.. it's... It's malware

How is it malware any more than a router or a switch?

@BernardoMeurer ok. and the last point:- do you believe/support in Why Open Source misses the point of Free Software?

Bernardo Meurer

@Pandya Partially, yes

@JohnRennie Those are all malware too

@BernardoMeurer you need to drink less - or perhaps drink more :-)

Bernardo Meurer

@JohnRennie Definitely the latter!

7:06 AM

Bernardo Meurer

I haven't had a sip in a whole week! Can you believe it?

@Pandya Does that offer anything that isn't on GNU/FSF's website or on any of Stallman's 300 talks?

@BernardoMeurer no, only some notable points from OSI are also quoted.

@BernardoMeurer Sad!
