@derobert haha, I set john the ripper at that guys passwd file from the other day and was about to kill it since it hasn't figured it out yet and he just posted a Q on cracking his root pw so he can log in. Guess I'll be nice and let it keep running...

for a few more days anyway.

@casey Wow, I'm surprised its taking so long

@derobert yea, me too. the wordlists didnt work and it has fallen back into its incremental search, so the likelihood it finds it in reasonable time is not good

@derobert FYI

@Fabby test5 failed

:D

I wonder how this lazy homework question got such a high score

I'm just amazed it shows my combined score here in the chat room...

@Gilles When I see smth lke that I always post the same comment (have a look again) ;-)

@Gilles: I remember that question had been answered many times, I can not find the link

@Fabby chat is network wide (though SO has its rooms separate from the rest of us). rooms have an associated site and users can pick a parent site for their chat profile, but chat itself exists independent of the q&a sites.

@casey Thanks...

@casey My fist question on EarthScience...

:)

And your answer on chemtrails made me laugh: "Say after me..." ;-)

@Fabby you might do better without the climate change rhetoric and just asking about the data / research availability :)

@Fabby it always strikes me as add that the chemtrail folks always complain about controls and never go after crop dusting or mosquito/pest control sprays, which really are chemical sprays :)

@casey I'll remember that one!

Yes, chemtrails are real: They're cause by crop dusters! Stay away from them! :D

the chemtrail guy also posted a meta q with a youtube video of "popular chemtrail evidence" which was clearly fuel venting / dumping...

(or maybe better not! They might not interpret the way I want them to...- ;-)

@casey Why that? Sceptics down-voting???

@casey (shake)

@Fabby could be that, or someone just feeling that rhetoric is somewhat unrelated to your question, or due to your tone they may take it as ranting

I'll re-read...

or they may just feel you aren't going to prove what you want with martian data

the difference in atmospheres, solar shortwave flux and terrestrial longwave emissions would make direct comparison a poor proxy for our situation

remove entire second paragraph?

Remove question?

:(

nah, the question can say

I'd just focus it on the title, looking for the data

Could you do me a favour and edit it for me?

im sure NASA has some products, but im not familiar with them

@Fabby i can a bit later

(because that's what I have in my head and it's kinda hard to remove anything...)

@casey thanks!

@Fabby isn't the size of the Martian icecap primarily dependent on NASA's funding needs?

hmmm

the Martian icecap has been increasing these past few years, while the Earth one is decreasing

Martians are stealing our ice!

if you say that with a child voice and in a hot summer, it would add a lot more of importance

@Gilles :D

Reminds me of a quote attributed to Paul Erdős: “when I was born the universe was thought to be 10 billion years old. Now it's thought to be 20 billion years old. Therefore I am 10 billion years old.”

I know that time is relative: when I was a kid, time used to be slower then now that I'm old!

;-)

@Gilles where did you find that? (my google search isn't giving me much info)

@Fabby the Martian icecap has been increasing since there didn't used to be one, until NASA needing funding

for the Earth icecap, there's plenty of stuff around, down to articles in the popular press about polar bears

@Gilles What's the Unix command to have a store-and-forward mail server start sending mail to a mail server that connects using SLIP?

It's finger ;-) :D

@Gilles The only thing I've found is a site that doesn't quote any sources, is called "skepticalscience" and just states that the polar ice caps on Mars are decreasing...

:( :( :(

@Gilles jokes aside, NASA's recent funding needs in part derive from our congress' assault on public funding of anything earth science related, but in particular anything related to weather / climate

even my Ph.D. funding has been negatively affected by it unfortunately

The current republican majority believes they can disprove climate change if they just stop spending money on studying it while some of them and their PACs privately fund their own anti-science projects

@casey Ouch!

What's the title of your PhD?

I found some stuff... I think I'm going to delete my question...

@Fabby something along the lines of "A numerical investigation of the dependence of the circulation of low-level mesocyclones on the characteristics of the outflow and the environment."

@Fabby or you could self-answer it

@casey I'm only finding pseudo-science...

@Fabby not surprising. One of our congressmen recently claimed to disprove climate science by referencing CO2 concentrations on mars and its much cooler temperatures compared to ours.

@casey Idiot!

People with no scientific background who wouldn't even know the difference between an endothermal and an exothermal reaction...

@Fabby our reigning idiot is Sen. Inhofe (R-OK). He "disproved" climate change this winter by picking up a snowball on his way into work to show "its cold out there"

What is that avatar of yours? Pilot's wings???

@Fabby my captain wings

@casey weather isn't climate...

@Fabby a distinction that eludes many

@casey Is there also smtg like lieutenant's wings then? (looking stupid, I know...)

@Fabby no idea, those are civil wings. our first officer wings were the same but without the star. I have 2 of those laying around as well. Our ranks were only displayed by those and our epaulets / jacket stripes (3 for FO, 4 for CA)

I used to fly those ^^^

and there is a pretty good chance I've flown that specific plane

:D I always used to fly Continental to the US back in the days that I worked for a US company!

(good service and cheap)

So you're a pilot, a meteorologist, a programmer...

yep

Do you paint and make sculptures and construct buildings too?

;-)

:)

@Fabby that smiles means, that he does, and also maintain a kingdom, fights monsters, and get profit in the process

@Braiam well i did take part in an orthodox wedding in Romania where they place crowns on your heads and proclaim you king and queen of your household. (I forget the exact phrasing, but something to that effect and starting your own lineage). Not much of a kingdom though - just over a quarter acre of land and only one 21 month old vassal.

@casey Oh, wow, that's awesome!

I take it you're a pilot then?

@casey who said that kingdoms grows in a night? :P

@HarryCBurn yep

@casey Awesome job.

@HarryCBurn the flying part and the overnights were fun, the rest of it was generally annoying, particularly the scheduling.

@casey You don't/didn't like it?

i liked the flying. working 12-15 hour duty days separated sometimes by as little as 8 hours in 4 day blocks, sometimes extended to as many as 6 days starts to wear on you

When I was a low seniority captain I was living about 4 hours from my base (too close to have flights unfortunately, so I drove). 4 hour drive (usually 8 am - noon), 4 - 5 days at work, 4 hour drive home (usually 2 am - 6 am), sleep half of that day, at home the next day and back to work the day after.

and being home 36-48 hours a week on average where you are sleeping off around 16 of those hours sucks if you are trying to have an semblance of a normal life

there were schedules that did 3 or 4 one-day trips a row with a few days off between that kept you home every night but you had to be really senior to hold those lines

the lowest seniority reserve schedules only had 11 days off a month and the senior ones went up to around 17. I had some pretty decent schedules as a senior first officer

...but first officer pay sucks

for most regional carriers first officers are going to make low to mid 30k /year, maybe up to 40 if you stuck at it for 15 years. the most junior captains made mid-high 60k / year (at my company)

i was also there during the economic decline and contract negotiations, neither of which are pleasent

hello

don't know why my text background is tan in color, but i will begin anyways?

@shaggy because you are special (?) and we want you to know it

I'm new to bash/terminal, and I'm on Mac, I know I hear the sighs already. Regardless i was just trying to get a little help on navigating directories by terminal, I understand cd, ls, pwd, and all of that but that is all in my root directory /user/"my username"$

@Braiam hah, well thanks, is it a feature for new members or something?

@shaggy the style sheets give your own text a different bg color is all

@casey Wow, that sucks.

anyways just trying to figure out how i get back to the subdirectory (don't know if terminology is correct) where I am able to navigate through my libraries and my 'main' applications folders

cd ..?

I'm no expert either, I could be wrong.

Or just cd takes you to your home dir.

cd .. takes you up a level in the filetree.

@casey ahh I see, I frequent other chat boxes that don't have this feature is why I was unaware.

@casey Sounds worse than I expected. And these people are still around even though proof of climate change continues to increase?

@shaggy its based on the site css. on chats associated with beta sites e.g. the difference is much subtler, but is there

@HarryCBurn from what I have experiences CD takes me home, or if i name a directory, such as cd desktop, i go to desktop

@casey gotcha

@shaggy And where are you trying to get to?

im trying to get back to the sub directory with: Applications, Library, System, Users

@shaggy cd with no arguments takes you $HOME. cd with an argument takes you to the argument. if it doesn't start with a / it is relative to your current directory and if does start with / it is absolute path

@shaggy cd /

@casey I used to assume commercial pilot pay was good because it was such a responsible job. Then (as I may have mentioned) I sat next to a commercial pilot one time and had a chat with him.

@casey wow that cleared it up. perfect explination

glad it helped

I hit a brick wall trying to get to all of my executable, and when I "cd applications" it was basically a blank app folder that was specific to my user.

@Gilles Those goddam evil Martians.

well that solves my issues for now, I don't really understand why mac implements 4 different "applications" folders with the same name. I really enjoy navigation by terminal though, eventually I hope to put together a cheap little linux box to mess around with and learn from, and hopefully then you shall see more of me.

thank you all for your help. and everyone have a good day and take care. :)

later

I just came across a mention of Numba. I'd literally never heard of it.

@FaheemMitha ^^ they basically statically link the llvm jit compiler to do fancy stuff

@casey I see. But mostly in numpy, it seems.

Have you used it?

nope. Unlike most of the folks who really want a tool like this, I'm not afraid of writing Fortran or C and just calling that from python if I want

@casey That's what I used to do. With Boost Python and C++, though.

And it's a nasty amount of overhead.

If you watch some of those spipy 2015 talks on this and some of the other stuff like it one of their key selling points is "writing C is slow, with this you can write fast and get most of the performance!"

but if you are proficient with C or whatever, it isn't really that big a deal

I have played with cython, but not numba

@casey Well, the problem was more the Boost Python interface, in my experience. It was a pain to maintain.

And with two languages joined together like that, debugging was a pain.

@FaheemMitha i haven't messed with Boost much and (imho) interop with c++ can be a general pain just due to the name mangling. extern "C" {....

@casey Well, I used to use the type auto-conversion feature. Which was a maintenance headache.

and its funny seeing some of the cython stuff where most of the speedup potential boils down to "lets add static types to this python code!! we can get 75% of the performance of a pure C extension!"

though in my experience, if you are already doing most of your stuff in numpy you aren't going to do a whole lot better with extra tricks like that since the numpy core is optimized compiled code. same for scipy which for some stuff links directly to blas or lapack
