Sorry was busy over the weekend, let me know if you need any help with command line
any time you use
rm you have to quintuple check your command matches your intent. ALWAYS
@ringmaster I get that that is funny but I wouldn't post that here where people are looking for help
rm -rf / This deletes your entire filesystem. Don’t do it.
@davidjcastner Sorry, that was a poor introduction into your community on my part.
I got an email from Meetup this morning saying I might be interested in your group. I poked around the page and ended up here somehow. My main question is this: Everyone here seems to be writing javascript; is that a focus or just coincidence?
We focus on the MEAN stack which means (no pun intended) that we use javscript
Any coding is okay. Web development is the primary trend however.
but you are welcome to discuss any programming, we mainly are encouraging people to learn coding
My acronyms re getting rusty, I think.
Right now I'll waist deep in the linux CLI + bash + python
Currently, I’m an Elixir dev, and Ruby/Rails. Before that, PHP. Before that, Delphi. All for $. With smatterings of everything everyone’s mentioned so far either for $ or for fun.
Well, that’s nifty.
@SimplyPhy for CLI, the best recommendation I have is to just keep using it. May eventually you end up crazy like me and have a secure shell app on your phone so you can connect to your house via the command line xD
Also, this is a great book/PDF http://linuxcommand.org/tlcl.php
I have three different CLI screens I can see right now @_@ gonna be a crazy day
cool, and I’m glad @owen winkler wasn’t here to answer my question in real time
i might have been foolish enough to go ahead with his recommendation
I once saw someone leave that command with sudo in front of it on a whiteboard. They said "run this command to make your program faster, uses less memory"
Can’t
npm upgrade node directly?
It’s hard to imagine getting by in node without having
npminstalled already, and if it can do the job, that seems useful.
@ringmaster I believe that it can, but this is the easiest way Install Node. Npm is included in the node install starting with version 4
Running bash scripts from remote sources make me a little… something.
I know I'm the only person in the world that finds shabang jokes funny xD but they amuse me everytime. #!
I’m sure it’s fine, but healthy fear is healthy.
I agree running bash scripts without knowing what they do is generally not a good practice
however, I'm seeing more software tools being installed this way nowadays, rather than the deb package manager
This is a no-fly in my company, since we use RedHat Software Collections. If there’s something that needs installed that isn’t in SCL, we have to hand-roll a package and commit to maintaining it, which is usually more trouble than just using some other pre-existing package. Suffice to say, installing things we intend to have on a server via 3rd party shell script is a big no-no. Obviously, YMMV, since we’re definitely purposefully strict.
The SCL package for node is old. It’s a point of contention, since the devs want new and shiny, and the ops guys want our servers not to asplode.
lol understandable. I'm a one man full stack dev, so i get the luxury of upgrading when I'm ready to
so if i download nodejs from the site, via the installer, and i already have node.js installed, will it successfully overwrite without jacking anything up, to your knowledge?
It's a crazy world. When I was younger never thought I'd be able to pull a computer out of a drawer the size of a deck of cards, stick a piece of plastic in smaller than my smallest fingernail and boot up a full fledged computer.
that’s how i like to dl things for now, generally speaking
yay! and npm-debug.log is back :D
I’m happy
@SimplyPhy if you have issues let me know, but I change/overwrite versions using those scripts all the time
even though I’m using macOS, i still always feel like i’m going to do something akin to messing up the registry in windows using the terminal
i’m good with using it for version control and github stuff, but once the real codes starts buzzing in there i’m scared

I totally recommend getting a raspberry pi (I have old ones you can have if you want an old one) and just doin' stuff with it on command line. If you screw it up, you just reinstall the os and keep truckin' along.
A cheaper and potentially future-useful alternative is to use Virtualbox.
so for example: npm install -g typescript
I use VirtualBox on my win machine. It's nice. But a pi is more fun!
where do you put that? or does it matter? does it just go wherever it’s supposed to within your path>
@Lilyheart Full disclosure: There is a stack of EeeBoxes to my left. :wink:
@SimplyPhy come to blue bell/east norriton/Plymouth meeting for lunch one day and I'll hand one off to you.
Lilyheart @Lilyheart nods yes.
so again, does it make any difference what your active directory is when you runs npm installs, like
npm install -g typescript ?
giving it a go now..
@SimplyPhy it matters for using npm install without the global flag
i thoguht i was an admin on the terminal
i’m researching how to make myself an admin now
put
sudo in front of the command for a quick boot in privlige. You are not always admin, that is locked down.
Super User DO!
Tip: If you run a command that requires SU privileges but forget to use
sudo, you can just type sudo !! at the next prompt and it’ll run the last command again with SU privs.
well it worked, and doesn’t appear to be a frightening outcome, so i’m pleased
Jus' sayin' don't using it willy nilly
doesn’t seemed to have hurt anything though, so yay
hmm, typescript looks kind of like javascript coupled with c# (to noob me)
which makes me think it’s probably like unityscript
I need a light sensor to put outside so the lights turn on in here when it's so dreary out.
sometimes just figuring out “what something is”, both functionally and structurally is really annoying
example: right now i’m reading about JSON
$schemas, and answering the question “what comprises a JSON $schema” is a big pain in the ass
it’s like the devs/doc writers secretly want to waste peoples’ time
@Lilyheart i like that adage xD
are they authentication, or just documentation specs?
okay the short version is a schema is how you structure your data (in case JSON format)
or validated, rather
yes, so as an example: you might have a user collection, the schema would check thigns like each user object has a username field, an email field, etc
it would fail any tests that is associated with the schema (the schema is an abstraction, and you can find libraries that provide validation for you). You can say each username is a string and must be between 8 and 50 characters
here is an example:
UserSchema = new SimpleSchema({
"email": {
type: String,
label: "Email",
regEx: SimpleSchema.RegEx.Email,
max: LIMIT_PARAGRAPH_CHAR
},
"confirmEmail": {
type: String,
label: "Confirm Email",
optional: true
},
"username": {
type: String,
label: "Username",
regEx: new RegExp(PATTERN_USERNAME),
min: LIMIT_USERNAME_CHAR_MIN,
max: LIMIT_USERNAME_CHAR_MAX
},
"password": {
type: String,
label: "Password",
regEx: new RegExp(PATTERN_PASSWORD),
min: LIMIT_PASSWORD_CHAR_MIN,
max: LIMIT_PASSWORD_CHAR_MAX
},
"confirmPassword": {
type: String,
label: "Confirm Password",
optional: true
}
});
then my simpleSchema library has a validation function I can call that will throw an error if a user object doesn't pass
i have to go unfortunately, i’ll be back before 5
thanks @davidjcastner
simplyphy sends brownie points to @davidjcastner :sparkles: :thumbsup: :sparkles:
okay feel free to ask me more questions about it later
