I work with similar sets of tables a lot.
01:13
<@Reiv>
I decided long ago that giving them meaningful aliases was a hell of a lot easier to work with.

It's got small smatterings of hungarian notation, but I have my reasons. >_>
01:14

Magyar raiders rampaging through your code?
01:14
<@Reiv>
All tables are renamed, eg. odw.odw_foo_bar_etc_install to t_inst
01:15
<@Reiv>
The t_ bit at the frost really isn't strictly needed, but it does a couple things.
01:15
<@Reiv>
First, if I have to start futzing with subqueries, I use s_inst for the internal one, so I can call t_inst = s_inst and there's a minimum of chaos~
01:16
<@Reiv>
And it means that I can hit ctrl+F and find the table references quickly without hitting false positives.
01:16
<@Reiv>
Also helps with visual scanning, 'cuz it gives a reasonably consistent 'look' to a table alias, which can occasionally help fix brainfucks.
01:17
<@Reiv>
"Oh, right. I forgot to use a table name on that one." etc

01:56

Reiv: Notepad++ has a non-regex mode that lets you use \t, \n, etc. as codes.
01:56
<&McMartin>
If it's a DOS thing you may have to call it \r\n?
01:59

There are extended regex mechanisms that do counting; I do not know if NP++ has them.

I don't know anything about sql server and it looks like you're in the specifics neighborhood.
03:46
<@Reiv>
woe
03:46
<~Vornicus>
apparently some of the tools I could really use are actually in later versions of javascript, but I have no idea what stuff various browsers implement
03:47
<~Vornicus>
and my attempts at finding out have been less than successful.
03:47
<@RobinStamer>
Vornicus: what specifically?
03:47
<~Vornicus>
RobinStamer: well at the moment I'm looking at object.keys, which show up in js 1.8.5
03:48
<@RobinStamer>
Ah
03:48
<@RobinStamer>
You can fake an implementation: function objectKeys(o) { var a = []; for (var k in o) { a.push(k); } return a; }
03:49
<~Vornicus>
I figured I could shim it in.
03:49
<@RobinStamer>
Honestly your best bet is just to add shims or find a shim-lib.
03:49
<@RobinStamer>
IIRC there's one around for all the Object stuff
03:50
<~Vornicus>
But as of right now I don't know what version of js any browser is using at all, and I don't know how to find out.
03:50
<@RobinStamer>
I don't recomend going about it that way.
03:51
<~Vornicus>
I was hoping to establish at least a baseline.
03:51
<@RobinStamer>
Code for 80% of the browsers you will support, and test those.
03:51
<@RobinStamer>
(I include different versions in "browsers")
03:52
<@RobinStamer>
Then when you get bug reports for older versions out of that add shims as needed.
03:52
<~Vornicus>
RobinStamer: right, but the difficulty is
03:52
<@RobinStamer>
This way you're not adding shims when they're uneeded.
03:52
<~Vornicus>
I don't know what those browsers support at all.
03:53
<@RobinStamer>
I'm saying it doesn't matter.
03:53
<~Vornicus>
But then how do I know what 80% of browsers do?
03:53
<@RobinStamer>
V8 doesn't support the full v1.8.5 spec.
03:53
<@RobinStamer>
But it has all the Object stuff.
03:54
<@RobinStamer>
IE: implementations are likely to support /parts/ of the new version.
03:54
<@RobinStamer>
Which is why you test for /features/ when coding in JS.
03:54
<&ToxicFrog>
RobinStamer: right, but the problem is figuring out which parts
03:54
<&ToxicFrog>
Short of "writing a test for each feature and running them all against every browser version one wants to support"
03:55
<@RobinStamer>
Create a unit-test page, then open it in each browser? That's, what, a 3-hour project at worst?
03:56
<~Vornicus>
Since I have no idea what browsers support what language features - and my attempts at finding out are coming up short, with the best resource I've found only covering DOM actions and being 2 years old - I can't even figure out what tools I actually have.
03:57
<@RobinStamer>
Right
03:57
<@RobinStamer>
So code with the tools you think you have.
03:59
<@RobinStamer>
Because in all likelyhood, whatever you use, most browsers will probably support most of it. Digging around for each little feature in the browser's documentation isn't going to help.
04:02
<~Vornicus>
"what tools I think I have" is kind of fuzzy.
04:02
<~Vornicus>
like, if that's my thing I should just avoid the entire js library and write my own shims for absolutely everything.
04:03
<@RobinStamer>
I'll rephrase
04:03
<@RobinStamer>
"Assume you have a tool until proven you don't"
04:08
<@RobinStamer>
Because fretting over having it or not is just wasting time.

I had a human guide.
04:56

In 2004.
04:57
<&McMartin>
The rest was just playing catchup.
04:57
<&Derakon>
McM's been wrestling with learning how things work lately.
04:57
<&Derakon>
But the underlying "there are vertices and transformations and so on" hasn't changed.
04:57
<&Derakon>
Nor has the ability to think in 3D, which is absolutely vital to getting anything done.
04:57
<&McMartin>
Except in a few places where it was more "well, that was dumb of us, let's pretend that never happened"
04:58
<&McMartin>
I believe "OpenGL For Dummies" is actually "Use Unity"
04:58
<&Derakon>
Anyway, all that isn't what you'd use to start out; you'd use immediate mode because it's much more accessible than GL3 or whatever the current version i
04:58
<&Derakon>
is.
05:00
<@celticminstrel>
So if I want to add an attribute to the current function, I need to set this.constructor.attr, not this.attr, right?
05:00
<&Derakon>
Uh, context? Language?
05:01
<@celticminstrel>
Javascript
05:01
<@celticminstrel>
Or maybe I should just do it properly and make a class.
05:04
<@celticminstrel>
Somehow.
05:04

Is f a class instance or something?

Is the apply() function static when it shouldn't be, perhaps?
05:24
<@celticminstrel>
f is a function.
05:25
<&Derakon>
Well, clearly it needs access to itself for something. I've no idea what the apply() function does though.
05:25
<@celticminstrel>
The array is used as the list of arguments to pass to the function.
05:26
<@celticminstrel>
So the same as in Python, if I recall correctly.
05:26
<@celticminstrel>
Or the star operator.

<@RobinStamer>
celticminstrel: in that setup, you would just assign to `this`
06:20
<@RobinStamer>
Passing f as the first param makes it `this` in the function's call scope.
06:24
<@RobinStamer>
f.call(x, a[0], a[1], ..., a[n]) is the same as f(a[0], a[1], ..., a[n]) except `this` is guaranteed to be whatever `x` links to. f.apply(x, a) is the same except instead of it being multiple arguments to .call() all the arguments are just in an array.
06:26
<@RobinStamer>
(There's also .bind(), which is newer, but slower on V8 compared to making a custom closure to do the same.)
06:27
<@celticminstrel>
...oh.
06:27
<@celticminstrel>

(And potions, which is odder, but whatever.)
06:32
<@RobinStamer>
Also, just an FYI, if `this` isn't anything (IE it's not being called with .apply(), .call() or as a property and it's not a .bind()'d function) it'll be the global object. Which is either `window` or `document` in a browser context (I forget which, sorry) or `globals` in node.js (note that the REPL has a seperate `globals`, which means a seperate Object and Array and so forth)
06:32
<@RobinStamer>
So your `this.constructor` trick was just applying stuff to the global object's constructor property.
06:33
<@celticminstrel>
Actually, it was being called as a property.
06:33
<@RobinStamer>
You could've used arguments.callee though, however that's being deprecated.

14:38
<&ToxicFrog>
So paste the URLs into wget or something
14:39
<&ToxicFrog>
Personally I would happily pick Chrome or Opera over Firefox simply by virtue of the fact that you don't need 16GB of memory for them to be usable
14:39
< Syk_>
chrome uses more RAM
14:39
< Syk_>
this isn't 2009
14:41
< Syk_>
Chrome is sitting there with FB and GMail open: 755MB
14:41
< Syk_>
FF has 15 tabs open, and I'm downloading 2GB of music: 828MB
14:47
< Nemu>
I think it's time we questioned 755 MB
14:47
< Nemu>
That's a lot of memory
14:47
< Nemu>
But I'm not a software engineer, so what do I know?
14:48
<&ToxicFrog>
Chrome, for me, is using 2GB of memory and has 50 tabs open.
14:50
<&ToxicFrog>
IME, firefox chokes and dies before it even reaches that point, although to be fair it's been a while since I used it heavily.
14:50
<@froztbyte>
firefox is far better than chrome at the moment
14:50
<@froztbyte>

14:50
< Nemu>
Yeah, it does that
14:50

Really annoying.
14:51
<&ToxicFrog>
It uses 50MB on windows, what have they done
14:53 * ToxicFrog does some fiddling with FF, determines that with 50 blank tabs open it sits at around 400MB, but the tab bar went to shit 30 tabs ago anyways

I'm measuring the response of one of our cameras to light.
16:59
< Derakon_>
Note that the response is nonlinear. We want to linearize it, which means we need to characterize the response curve.
16:59
< Derakon_>
Each point in this plot is the average of all of the pixels in the camera -- but the pixels each have their own differing response curves (sometimes differing drastically).
16:59
< Derakon_>
So basically I have 528 * 512 versions of this plot, each of which needs to be fitted individually.
17:02
<@gnolam>
>_<
17:04
<@gnolam>
You should always display the non-linearized value first. Just so you can implement an actual "Enhance" button.
17:05
< Derakon_>
Well, this is a postprocessing step.
17:05
< Derakon_>
You collect the raw data, then you run it through the linearizer.
17:05
< Derakon_>
We have a bunch of these. Some of them really are basically "enhance" buttons.

And the residuals are still lousy.

18:43
< JustBob>
I was required to 'write a script to solve function bleh,' and technically I was supposed to use if loops or something fancy like that.
18:43
< JustBob>
My script consisted of me copy-pasting and editing the same four lines 30 times.

19:57
<@Alek>
Why does %r sometimes print things with single-quotes when I wrote them with double-quotes.
19:57
<@Alek>
Python is going to print the strings in the most efficient way it can, not replicate exactly the way you wrote them. This perfectly fine since %r is used for debugging and inspection, so it's not necessary that it be pretty.
19:57
<@Alek>
This.... bugs me. -_-
19:58
<@Alek>
why is one way more efficient than another? what are the reasons for choosing one over another?
19:58
<@Alek>
that is, why does PYTHON choose one over another?
19:59
< Derakon_>
Because that's how it was coded.
19:59
<&ToxicFrog>
Alek: it's more efficient to not record whether the string was originally defined with "" or '', and just use one (picked arbitrarily) for output.
19:59
< Derakon_>
It might decide to always use " unless there's a literal " in the string, in which case it uses '. I don't know if it's that smart.
20:00
<&ToxicFrog>
Otherwise it would have to keep track whether the string was defined using "" or using '' (and what should it use when you use ('foo' + "bar")?)
20:00
<&ToxicFrog>
Derakon_: it actually uses '' unless there's a literal ' in the string, in which case it uses ".
20:00
< Derakon_>
D'oh~
20:02
<@Alek>
yes, but why is it reproducible that it picks single for certain things and double for others? instead of random.
20:02
< Derakon_>
Because the code is deterministic.

Why, in the name of all the gods, would you want unpredictable code execution?

\v (vertical tab) actually displays the male symbol.

and \f (formfeed) is the female symbol.
20:48
<~Vornicus>
that's not python
20:51

those are escape sequences. listed in the escape-sequence chapter of LPtHW.
20:52
<~Vornicus>
one more strike against lpthw,they're only that on windows command prompts
20:52
<~Vornicus>
If I tell my computer `print '\v\f' I get three blank lines.
20:53
<@Alek>
this is actually ActivePython in Powershell.
20:53 * Alek shrugs.
20:53
<@Alek>
haven't gotten past that yet.
20:53
< Derakon_>
The point is that not every escape code is valid everywhere.
20:53 * Alek nods.
20:53
<@Alek>
fair point.
20:54
<@Alek>
\v is multiple blank lines, then. but what's \f do?
20:54
<@Alek>
as in, \v moves the cursor several lines down, like \t moves it several characters over.
20:55
<~Vornicus>
\f is one line down without resetting horizontal position, iirc, one moment
20:56
<~Vornicus>
Yes, confirmed
20:57
<~Vornicus>
so doing print "abc\fdef" gives me abc on the first line and then def on the second line indented three spaces.
20:57
<@Alek>
and "abc\vdef"?
20:57
<&ToxicFrog>
FF is actually a page break; it instructs the printer to eject the current page and continue printing on the first line of the next.
20:57
<&ToxicFrog>
Most terminal emulators interpret FF equivalently to a raw CR, ie, down one line.
20:58
<&ToxicFrog>
Er, a raw LF.
20:58
<@Alek>
ah.
20:58
<@Alek>
idly, \b works funkily in certain occasions. >_>

while True:

<@Alek>
for i in ["/","-","\\","|"]:
20:59
<@Alek>
print "%s\b" % i,
20:59
<&ToxicFrog>
A vertical tab is the same as a horizontal tab except the tab stops are (traditionally) every six lines rather than every eight characters.
21:00
<&ToxicFrog>
In practice no-one uses either anymore for their original purposes, so the meaning is "whatever the program, language, and terminal you're using want it to be"
21:00
<@Alek>
that tosses printout on the right edge of the shell, and raw-LF instead of overwriting.
21:01
<@Alek>
(where \r instead of \b just overwrites it in place, on the left)

(the short answer is, depending on which technique you use, you'll either need to configure an encrypted device and then create a normal filesystem on it, or create a normal filesystem and then mount an encrypted layer on top - the linked page discusses both approaches)

Okay, thanks.

(what you choose depends also on what you want; block device encryption, for example, encrypts everything including filesystem metadata and partition tables, but is all-or-nothing, while overlay encryption can encrypt individual directories)
