Moonwards

Hohmannfan

17:42

I saw Kin-Dza-Dza today. A quite different type of sci-fi than I am used to.

kim holder

18:04

i'd never heard of that. the original or the remake?

Hohmannfan

The original.

kim holder

looks like i could watch it on youtube. i might put it on my list.

Hohmannfan

yes, keep a sci-fi/fantasy list. About 30% of the things I mention are perhaps not worth the time, so just put them on a list and ask me to reconsider them about half a year later :)

kim holder

18:35

how are you for time these days, Hoh?

Hohmannfan

18:55

The rest of that part is internet time. Subtract some time for reddit and SE, and you have what I can use for Moonwards. Not a lot, but a little. It is probably a good idea to think about what I should spend it on.

I have enough time to do things. Yeah, the school work takes some, but it is manageable. Spring is coming, so I spend some time cutting down trees and stuff and preparing some vegetables. Of the then remaining 'luxury free time', I choose to spend over half on reading as I have found some interesting stuff and has a huge library available.

kim holder

trees :)

Hohmannfan

I never get those two words right.

kim holder

well, i don't know how complicated or time-consuming it really is, but i wondered if you could get that Commentics service working on the website.

Hohmannfan

Set up comments, ok.

kim holder

let me post the link again. commentics.org

maybe it is a lead-in to working with databases.

Hohmannfan

18:59

Allowing on-site feedback for all the content is probably the end goal, but as a first step having something that works at all is most realistic.

kim holder

it's nice that you do some gardening.

@Hohmannfan yes, ideally i'd like to scatter comment sections around all the pages, but we'll see. it isn't so important really.

not until we are able to have real user participation

Hohmannfan

My mother, and especially my grandfather (I live at his place now) are gardening enthusiasts. It is difficult to not become interested.

@kimholder Is it just me, or should the commentics frontpage really have a comment section so people can see it in action directly?

If this is the only form for security I am very worried.

kim holder

it does have a demo section that i just posted something to

and it automatically pulled my avatar from google

@Hohmannfan is that from the guide?

Hohmannfan

Yes.

kim holder

i really know nothing about security or databases, but to change that database, i think you'd need to be logged on to the server, wouldn't you?

Hohmannfan

19:12

Also, this: " [...]You can do this in your website control panel". Uhm...

@kimholder I suppose so, obscurification of the webpage is really not what we are trying to do.

Perhaps I should try creating a database first? That is a useful experience anyway.

We have a server, so why not.

kim holder

for sure. Dreamhost has software installed for that. let's see, what's it called...

and how would you access it...

it's phpMyadmin

Hohmannfan

is it durin.dreamhost.com or org?

kim holder

.com

yes, you have access to the forum database, but there is a separate sign-in for phpMyadmin

Hohmannfan

I am going to try to get used to doing things remote on the server.

Looks like I have to do this over ftp

Looks like the server is Ubuntu :)

kim holder

:D well, that's the way you like it

Hohmannfan

19:29

ftp is a very different thing than working with a regular shell-like thingy though. Hmm.

kim holder

i may need to create a new database and give you access.

Hohmannfan

I am pretty sure I am never going to learn how to use a website control panel. Way to complicated compared with a shell environment.

WANT: this VERY!

kim holder

oh... huh, look at that. now you won't have to impersonate me. :)

i never ran across that before.

oh - you are already there

but it is isolated

you can't touch moonward's files from there

i knew i tried to give you that access before and couldn't

do you want me to email you a new password, or do you have it somewhere?

Hohmannfan

19:46

I have an account? I remember something about that, but I am not sure I figured out how to make use of that.

kim holder

you weren't checked as a shell user, i've done that now

Hohmannfan

@kimholder Can I change the password myself afterwards, in that case, how?

kim holder

[kim wonders if it is really a good idea to tell Hoh how to create a password she can't then check, that gives him shell access on the server...]

:P

Hohmannfan

You can still remove any powers I have, right?

I am just a little concerned about the sending-passwords-over-email part

kim holder

yes, that isn't good either.

yeah, i see where i could delete you if something absolutely crazy happened.

Hohmannfan

19:51

I can give you some simple instructions about how to send it to me using pgp in a few days.

kim holder

however, in order to create the password, i think you'd have to log on to the account, which is a different password you don't have

what if i write it down and send you an image?

Hohmannfan

It would work as follows:

1 I send you a public key. There is nothing wrong with people knowing that.
2 You encrypt the password using that key.
3 Now only I can decrypt it, using my private key

kim holder

ok

also, if you root around, you may find the password you already have

Hohmannfan

Meh, new password sounds good to me.

kim holder

A: Can olivine be used to make glass?

The previous answer is not really helpful because you would need huge amounts of CO2 which are not available on the moon. You need 2 moles of CO2 to generate 1 moles of SiO2. You simply do not have that amounts of CO2. Furthermore, assuming you do someone get that CO2, you need to physically sep...

you know, that answer is useful, but i wish so bad he'd respond to the comment

it would be far more useful if i could talk to him about it.

Hohmannfan

Ready to do this password transfer? This should take no more than ~5 mins. This is going to be step-by-step.

kim holder

alright

Hohmannfan

I am going to send you my public key in an email. I can send it over open chat if I want, but the message is a bit too long for it to be convenient.

First step: we are going to install two things:

Gnu privacy guard (GPG)
Gnu privacy assistant (frontend for GPG)

Both are official GNU procjects.

To install them: "sudo apt-get install gpa gnupg2"

**Do not take my word that these programs are what I say they are. Use a search engine to confirm this**

kim holder

ok... i'll even do the last part just to make you happy... :]

alright, that's done

Hohmannfan

Ready for the next step? There should be no need for you to generate your own keys or anything, so we can go directly to you creating a message for me:

Launch the front end with "sudo gpa". A window should appear. It may ask you if you want to make your own key. Decline that.

kim holder

20:32

alright, now what?

Hohmannfan

If you now have a GUI everything is good. Next: check if you have got an email from me with an attached file.

kim holder

yeah, i already checked that

i opened it in gedit

Hohmannfan

Click "keys" in the menu. Select "import key" and select the file I sent you.

kim holder

ok. next?

Hohmannfan

Select "windows" in the menu, and go to "clipboard". Write the message.

kim holder

20:36

how long would you like?

8 characters? 10?

Hohmannfan

Just the password is fine, it does not really matter.

10 just to say a number

kim holder

okay, and now?

Hohmannfan

When you are done, click the envelope with a blue key on it. (it says "encrypt the buffer text" when you hover over it).

Then, select my key in the list in the upper part of the window you get.

The clipboard now changes to something like this:

kim holder

wow, it even advises that the ownership of the key hasn't been verified. cool.

Hohmannfan

-----BEGIN PGP MESSAGE-----

kim holder

20:39

yep, got that now

so, i insert that in an email?

Hohmannfan

Select it all, paste it to a file, and send it to me.

It is actually short enough to just paste in chat, but maybe SE does some formatting, so an attached file to anemail is probably best.

You are now done!

kim holder

you should have it now

gee, i should set this up so i can save a few things securely...

Hohmannfan

So, all these things were for a reason: Somebody could have all the emails and this conversation, and still not have a clue what you sent me.

kim holder

okay - give me sec - i actually haven't set up the other end

Hohmannfan

So, I am [email protected], right? The "allow shell access" stuff and new password may take some time to propagate through the interwebs. I am going to try login in after an hour.

This key stuff may look a little too paranoid, but this is actual security. It does not take a lot of time, and doing it once or twice to get comfortable with it can not really hurt in any way.

kim holder

20:53

nods wisely...

:]

Hohmannfan

Perhaps I can check if SE does any fancy formatting to the blob.

Nope, posting the message in chat works perfectly fine. No need to bother with emails.

kim holder

21:32

i'm surprised that isn't too long

Hohmannfan

perhaps They have exceptions for messages looking like PGP messages? Not surprising

-----BEGIN PGP MESSAGE-----
Version: GnuPG v2

Both when encrypting messages and when verifying signatures, it is critical that the public key used to send messages to someone or some entity actually does 'belong' to the intended recipient. Simply downloading a public key from somewhere is not an overwhelming assurance of that association; deliberate (or accidental) impersonation is possible. From its first version, PGP has always included provisions for distributing user's public keys in an 'identity certificate', which is also constructed cryptographically so that any tampering (or accide…

Post very long messages if you want, is looks like!

kim holder

that's kind of hilarious

Hohmannfan

Let me see if just the header is enough.

kim holder

but there is also a formatting thing for doing that anyhow - i just can't remember what it is

Hohmannfan

Yes.

kim holder

21:38

ok - so why did i get a thing the other day that my message was too long?

Hohmannfan

kim holder

when i copy/pasted that just now it was fine with it

Hohmannfan

Yes, for me too.

I have written way shorter things than that getting blocked

kim holder

is the magic simply copy/paste?

Hohmannfan

No, because I often write long stuff in an editor and paste it.

kim holder

21:39

i think i've gotten that message when i've done that too, though

Entire text of the wikipedia article. Something is broken

Are you or I going to write that meta question?

kim holder

um, it might be covered already, you might want to search

if not, i'm in the middle of brazenly suggesting how to make glass on the moon. But i'll do it later if you are busy.

Hohmannfan

22:35

@kimholder I got an explanation: Text containing newlines is not considered "too long"

kim holder

what does 'newlines' mean

Hohmannfan

Like the end of a line, it is a character.

Line break.

kim holder

put in a line break and you are good? pff, glad i know that now.

Hohmannfan

So, shift+enter to continue the rant :)

kim holder

exactly :D

Hohmannfan

22:46

A newline takes space just like any other characters, so we should clearly have all our code on one line to improve loading time :P

BRB, researching Mongolian whitespace.

i am researching the casting of glass in graphite molds, and the cooling process to yield glass of good clarity and strength

Hohmannfan

Ah, useful things.

kim holder

the answers to my glass-making questions on chem.se seem to have led me astray as much as they have helped

it doesn't really seem to be that hard, unless i'm really missing something

Hmm. Looks like I can not force a line to continue out of the text box.

kim holder

i have now started reading a public-domain book called 'Glass Manufacture'

i think i can speed read most of it and get the important things

it looks like glass doesn't actually need to be quenched, it just needs to cool over a few hours, and spend enough time in the temperature range where it 'anneals', so it doesn't have internal stresses due to cooling too fast

and contaminants don't seem to be a big deal. not even of iron.
