Q: How to setup multiple WiFi networks?

I go back and forth from home to school with my Pi. I just got the WiFi working last night at home using wpa.conf instead of wpa_supplicant.conf as the book I was using had the walk thru for that instead. I've noticed lots seem to use wpa_supplicant but I not sure why... Anyway, I know how to ...

Q: Rejection of edits on a wrong basis

One of the members who has a higher reputation than me rejects my edits on the wrong basis. As I know, on this site, we write Ubuntu and not ubuntu. Even when I write ubuntu, other members correct it. But one of the members has rejected some of my edits on a wrong basis(as I think) and rejects al...

@Zanna What's your editorial opinion on mysql and sql ?

Zanna

not knowledgeable about the topic... Afaik, SQL is a language and MySQL is a piece of software?

Byte Commander

Surely they should not be merged

But I wonder if we should have any sql at all, as if it's about the language standard, it should rather go to Stack Overflow, I guess

Zanna

not the same thing... maybe we don't need an SQL tag?

Sergiy Kolodyazhnyy

MySQL is one of many SQL databases, some questions under SQL are also tagged MySQL, which . . .seems redundant , maybe ?

Zanna

maybe for software related stuff? we have tags for C, C++, Python, Ruby.......... [long list]

Byte Commander

6:44 PM

SQL is just a language standard (which nobody ever completely followed)

Zanna

hmm

Byte Commander

I don't think a question can be about the SQL language and on-topic here

without rather being about a specific database implementation like mysql or whatever

probably the tag should be nuked and those 80 questions retagged with the appropriate implementation

Sergiy Kolodyazhnyy

@ByteCommander Info of the tag states "SQL is a programming language designed for managing data in relational database management systems (RDBMS)." So . . . should we edit info so that it says "a language standard " instead ?

Byte Commander

would be more accurate, but if we want to get rid of it, who cares?

Zanna

@ByteCommander seems sensible...

maybe a meta question?

Sergiy Kolodyazhnyy

6:46 PM

Well, do we want to get rid of it in the first place ?

@Zanna yes

On the related happy note, I got taken off waitlist for databases class and now at some point I should start learning SQL . . . em . . .well, one of them

Byte Commander

and those which are indeed not specific to an actual database system (i.e. general recommendation) might be tagged database

don't pick Oracle

Zanna

jealous

Fabby

@dessert :-) Very cute!

Sergiy Kolodyazhnyy

I'll either go with MariaDB or MySQL . . . it's not like I've any clue about either, these just get mentioned a lot apparently

Byte Commander

either e.g. MySQL/MariaDB, which is pretty common, or PostgreSQL, which is pretty good and close to the standard, from what I have heard. No personal exp with that one though

MariaDB is just the open source fork of MySQL

Fabby

6:49 PM

@dessert It's only when a big chicken walks into view that you see how little they are...

Sergiy Kolodyazhnyy

What about SQLite ?

Byte Commander

Both should be completely compatible, the SQL dialect they use is the same

SQLite is a single file database, which would run embedded in your main application instead of as a client/server like most others

Sergiy Kolodyazhnyy

Side-note: we have also dba.stackexchange.com for sending off-topic questions there

Byte Commander

It also lacks some SQL features, but I haven't extensively used it yet

Fabby

@ByteCommander Like a "Mint" tag...

Byte Commander

6:52 PM

I'm off for some tv... bye o/

Sergiy Kolodyazhnyy

See ya

Fabby

@Zanna Jealous of what and whom?

OK, I'll go work some queues then...

dessert

@Fabby they seem huge to me, they grow incredibly fast currently

Fabby

:-)

Yeah, but they're still smaller than your hand.

Zanna

@Fabby of @SergiyKolodyazhnyy, getting into database class

I wanna learn to write amazing beautiful SQL queries for SEDE

Fabby

6:57 PM

If you read the MySQL manual in its entirety, you will know more than what he will know after his course...

Sergiy Kolodyazhnyy

@Fabby Unless I also read the manual . . . while taking the course . . . In which case I'll be more confused than ever, and Zanna still wins

Fabby

And once you've read it all, it's fairly easy to keep up...

@SergiyKolodyazhnyy :D :D :D

Zanna

I can't read manuals

it goes in one ear and out the other

I can only learn by doing

Fabby

Ah... I'm a voracious reader.

Sergiy Kolodyazhnyy

@Zanna So . . . no audiobooks for you, right ? :3

Fabby

6:59 PM

@Zanna You have to read and do at the same time...

Zanna

I read other stuff. Just not techical instructions

Fabby

so you read the installation section first, then install

Zanna

@Fabby if it's that kind of manual, then great

Fabby

so basically; you read everything twice and then do!

Last time I read the entire manual was 3.x

Zanna

I'm studying other stuff... finding time for more self study is impossible. But when you go to a class, you are forced to do it haha

Fabby

7:00 PM

then I just read the diffs until 5.5 and then I started working for this company and I stopped reading tech manuals except internal ones.

Zanna

but thanks for the recommendation. I'll try to find time... some time

Fabby

:D Like learning GO is still on my TO DO list

as is travelling to India...

New Zealand

RegEx

Sergiy Kolodyazhnyy

It's really one of those things that depends on the person. Some learn by doing, others by reading. But mostly it's a mix for everyone. I learned a lot of my stuff by a mixture of things. Trying, then reading manuals, then trying again but smarter. AskUbuntu has been one of the things that pushed me to learn, which I otherwise wouldn't pick up

Fabby

I posted an answer on meta copy-pasting my Ubuntu [any key] answer:

Wow! That comes out weird!

Sergiy Kolodyazhnyy

Take this for instance : unix.stackexchange.com/a/425104/85039 I've not been interested in sed that much, but just for the question and because I had been having fun with it for no reason at all, I went and researched all the things

Fabby

7:02 PM

@SergiyKolodyazhnyy Yup.

Zanna

URGH left nav :( :(

also half time over :) :)

Fabby

Huh?

Half of the time of what?

And what left nav?

Sergiy Kolodyazhnyy

@Fabby Stack Exchange's new feature. They added left-side panel

Which eventually will come to all other sites as well

Fabby

Yeah, somewhere in July...

Zanna

it's horrible

@Fabby football

Sergiy Kolodyazhnyy

7:05 PM

@Zanna More like unnecessary.

Zanna

that too

Fabby

@Zanna Ah again: reading is more efficient then watching too: just don't watch and look at the scores for 1 minute every week.

Then you would have time to read the MySQL manual!

:D :D :D

Zanna

I'm marking an exam while watching

Fabby

:D :D :D

Croatia won From Argentina! Wow!

Zanna

@SergiyKolodyazhnyy hahaaa one of my higher voted answers is some weak sed-fu. It's funny, some of my stronger mysterious sed lines get less points ;)

59

A: Change all associations from gedit to another application

Running on 13.04+, update the file: /etc/gnome/defaults.list. sudo sed -i 's/gedit.desktop/sublime-text-2.desktop/g' /etc/gnome/defaults.list Credit to trent for the update to 13.04+ Pre-13.04: System wide associations: sudo sed -i 's/gedit.desktop/sublime-text-2.desktop/g' /usr/share/a...

The simple one ^^

Rinzwind

@Fabby what did you expect? Argentina would be better off with 11 fieldplayers and no goalkeeper :X

RobotHumans

Ouch, I can feel that burn from across the ocean.

Rinzwind

Messi can't win a game by himself. And here is where we all get to see Ronaldo is better due to having a team. Messi is the better solo player but this game is 11 vs 11 :+

Oh and @RobotHumans best rep you get when the answer is a simple copy/paste from a "man" page. Guaranteed a 10+ upvoted answer :X

same with "sed": simple sed commands people read and think they understand trump sed commands that confuse someone.

RobotHumans

Yeah. When your sed line starts to look like perl, it's time to stop.

Rinzwind

sure is :D

OH DAMN

Have the TV on and the intro to "once upon a time in the west" was on

INSTANT goosebumps.

Sergiy Kolodyazhnyy

7:25 PM

@RobotHumans I think this kinda goes back to the fact that sed can be convoluted, and people have no idea whether to upvote it or not :3 So those upvotes probably come from people who recognize the sed-fu, so I'd say those few upvotes carry extra value with them

dessert

@Rinzwind yeah, that’s one hell of a soundtrack…

RobotHumans

@SergiyKolodyazhnyy Haha. Yeah, it's like when we were writing tests and couldn't find the pin on the map with xpath to click and get a tooltip, so I just set all pins to one location to keep it centered, did the coordinates math, centered on where the pin should be with manual move-cursor, and fired a click event. To read it is obnoxious, but it wasn't solveable another way.

Zanna

yeah, like when you think muru might have upvoted your answer, then you feel way better than when you got 10 upvotes for an effort-free answer...

dessert

ennio morricone just rules

Sergiy Kolodyazhnyy

@Zanna Frankly, that's very true at least for me. In fact, it's one of the reasons why I stuck around on the site for so long

I wanted to "be as cool as them" @_@

Still don't feel cool , though . . . .
