Would you like to inspect the original subtitles? These are the user uploaded subtitles that are being translated:
1
00:00:00,490 --> 00:00:09,190
All right, guys, so before we dive into the setup, you may find that some of the things we are about
2
00:00:09,190 --> 00:00:15,550
to do may venture into areas that you're unaware of when working with a computer.
3
00:00:16,240 --> 00:00:21,370
Some of you may be more powerful users and some of you may just be new to all of this.
4
00:00:21,610 --> 00:00:25,910
And we want to give you a solid foundation on which you can build.
5
00:00:26,170 --> 00:00:29,170
So we want to show you things that you may not have seen before.
6
00:00:29,530 --> 00:00:37,150
And depending on what type of system you run, you may find that there are just certain features that
7
00:00:37,150 --> 00:00:39,150
have eluded you throughout your usage.
8
00:00:39,310 --> 00:00:44,770
You may be a powerful Excel user, maybe a powerful PowerPoint user, but you're just certain things
9
00:00:44,770 --> 00:00:47,450
to a computer that you haven't been in touch with yet.
10
00:00:48,220 --> 00:00:53,920
So when we're doing school in Posterous and over here, you can see I'm on my Mac.
11
00:00:54,760 --> 00:01:00,700
Well, certain systems use Unix or Linux or Mac.
12
00:01:01,000 --> 00:01:07,090
These are types of operating systems and Mac is very close to Linux.
13
00:01:07,630 --> 00:01:10,900
And then you have people that use this completely different paradigm.
14
00:01:11,140 --> 00:01:17,320
The majority of you may be Windows users, but what all of these computers have in common is that they
15
00:01:17,320 --> 00:01:19,240
use bits and bytes.
16
00:01:19,780 --> 00:01:25,230
And so there are ways in which you can communicate with your computer that you may not be used to.
17
00:01:25,600 --> 00:01:32,320
And before we get into setting up all of this that you see here, well, first we have to get into the
18
00:01:32,320 --> 00:01:33,610
setup of our databases.
19
00:01:34,060 --> 00:01:39,370
And postcrisis particularly is an interesting technology that you're learning, because although you
20
00:01:39,370 --> 00:01:46,360
have all of these tools to show you things visually, a lot of people like to run PostgreSQL in the
21
00:01:46,360 --> 00:01:47,080
command line.
22
00:01:47,930 --> 00:01:52,740
Now, you may be frowning and saying, we command what's the command line?
23
00:01:53,090 --> 00:01:58,540
Well, this tool may have eluded you throughout your PC usage or your Mac usage or your Linux usage.
24
00:01:58,910 --> 00:02:00,380
Not so much for the Linux users.
25
00:02:00,440 --> 00:02:05,000
If you're in the Linux space, if you're using a Boodhoo, you've probably found your way around the
26
00:02:05,000 --> 00:02:05,380
terminal.
27
00:02:05,960 --> 00:02:11,180
But basically there is this thing called a terminal.
28
00:02:11,750 --> 00:02:15,060
And on windows, it'll be called the command line.
29
00:02:15,680 --> 00:02:18,410
And so what that looks like is the following.
30
00:02:18,950 --> 00:02:20,750
It's a textual interface.
31
00:02:21,850 --> 00:02:23,980
So when you open it up.
32
00:02:25,140 --> 00:02:31,830
It may look like this, it may look a bit smaller, it may open up in a frame about this size, but
33
00:02:31,830 --> 00:02:37,770
depending on how you use it and depending on if you're familiar with it, it'll just open up in a basic
34
00:02:37,770 --> 00:02:37,970
way.
35
00:02:38,580 --> 00:02:44,790
And what it allows you to do is it allows you to interface with your computer from a text perspective.
36
00:02:45,450 --> 00:02:52,140
Now, there are multiple commands that you can run in command line and will reference some material
37
00:02:52,140 --> 00:02:55,670
that will help you supercharge your adventure down the command line route.
38
00:02:56,010 --> 00:03:03,030
But some of the most important ones that we'll be using are L's, which is list directory.
39
00:03:03,990 --> 00:03:05,700
You can also do a.
40
00:03:06,830 --> 00:03:12,980
Which will show you the directory and the hidden files files that you normally can see when you browse
41
00:03:12,980 --> 00:03:18,380
your system, there is change directory, which is KDDI change directory.
42
00:03:18,530 --> 00:03:24,680
And if you see if we go into databases, well, if we do list there now, we have a completely different
43
00:03:24,680 --> 00:03:25,450
file structure.
44
00:03:26,210 --> 00:03:29,660
And so this mimics us going into documents and seeing what's here.
45
00:03:29,960 --> 00:03:36,560
As you can see here, we're seeing databases and databases, dot, zip, and then when we're inside
46
00:03:36,560 --> 00:03:40,390
of databases, we can see France employee.
47
00:03:40,700 --> 00:03:47,140
But we see these files here, icon, questionmark dStore files that we can't see when we're in our finder.
48
00:03:47,720 --> 00:03:50,470
And so that's what's cool about using command line.
49
00:03:50,720 --> 00:03:56,960
It doesn't only look like a matrix hacking sequence, it's actually very functional when you start using
50
00:03:56,960 --> 00:03:59,990
it, when you're programming and doing a school and doing other things.
51
00:04:00,620 --> 00:04:05,720
And when we pop over into windows, you can equally use the same in command line where you do else.
52
00:04:06,320 --> 00:04:08,090
Well, that doesn't seem to work.
53
00:04:08,360 --> 00:04:10,310
Well, how do we do that in windows?
54
00:04:11,440 --> 00:04:18,520
Well, in Windows, the command is actually there, and that'll show you the directory, dear, and
55
00:04:19,330 --> 00:04:22,630
to change directory, it's the same thing.
56
00:04:22,630 --> 00:04:24,280
So we can do desktop.
57
00:04:25,010 --> 00:04:30,010
And then if we do, Daryn, here you can see what all is in the desktop.
58
00:04:30,370 --> 00:04:35,110
So you can see over here, we have back up that will right over here.
59
00:04:35,530 --> 00:04:39,220
And then we have two directories.
60
00:04:40,140 --> 00:04:41,020
And one file.
61
00:04:41,610 --> 00:04:49,290
All right, so with this, you have the power as a user to interface with your computer in a different
62
00:04:49,290 --> 00:04:49,490
way.
63
00:04:49,500 --> 00:04:56,580
And again, we'll be linking materials to push you along a journey to use command prompt wisely and
64
00:04:56,580 --> 00:04:57,680
successfully.
65
00:04:58,140 --> 00:05:03,570
But with this introduction, you have a solid foundation to know what we're talking about.
66
00:05:03,720 --> 00:05:09,180
When we start doing things like importing our databases into PostgreSQL and other things that we can
67
00:05:09,180 --> 00:05:15,450
do along the line, we will also include a section on specifically interfacing with Posterous in command
68
00:05:15,450 --> 00:05:18,990
line when we go into talks about how to maintain your database.
69
00:05:19,470 --> 00:05:21,180
So stay tuned for all of those.
