Challenge Given a string such as Hello World!, break it down into its character values: 72, 101, 108, 108, 111, 32, 87, 111, 114, 108, 100, 33. Then calculate the difference between each consecutive pair of characters: 29, 7, 0, 3, -79, 55, 24, 3, -6, -8, -67. Finally, sum them and print the ...

aaaaaand there we go

I think that, in general, banning builtins to any degree tends to make the challenge harder but not more interesting, which is a net negative, I believe.

@DmitryKudriavtsev That's impressive, seeing how you commented on it. :P

Guys do you have any suggestions for new commands for LGC?

Anyone know about ISP routing and networking?
Would there be technical limitations of an ISP that sells internet up/download bandwidth based on the total amount? So the user can choose (say every day or at least every month) what their respective up/down bandwidths should be as long as they total to the same thing? e.g. You could have a total of 40Mbps and one day set it so download is 35 and upload 5, then another day make download 10 and upload 30.

@HelkaHomba Depends on the type of connection. Notably, ADSL (asymmetric DSL) won't give you great upload speeds because the upstream is encoded in the crappy part of the signal.

I didn't know @NewLoopholeProposal existed

It always has. New loopholes just aren't very common

With my upvote, I deem it an official loophole.
Feature request: a stack snippet on the loopholes thread that lists all "valid" loopholes according to vote totals/ratio.
Although, it might be nice to review if the "minimum +5 score, with at least 2/3rds majority" rule is actually the best way to do it, since it seems like that rule was just arbitrarily decided upon when the thread was posted.
Given how highly-upvoted everything is, it might be worth increasing the +5 requirement, or altering the required super-majority.

That's fair

3:01 AM
@HelkaHomba I think there is necessarily an imbalance between upload and download speeds (at least, if you're not doing anything contrived and "unnatural") solely because reading is faster than writing. It's generally much quicker to copy and send data than it is to create it.

How is everyone doing?

@El'endiaStarman I get why ISP's do it that way normally, but for a growing ecosystem of online content creators, having the option to have upload speeds larger would be nice.

@confusedandamused slightly confused, somewhat amused, but mostly tired.

Sorry I got in the way conor

3:05 AM
@El'endiaStarman Like if there are no technical challenges on their end, why would Comcast care if I'm uploading lots of stuff?

@quartata would cg be good at this? It's basically a regex

@HelkaHomba Well, which is greater, the rate of consumer growth or the rate of creator growth? (I'm actually not totally sure.)
@HelkaHomba I don't think I've ever heard anything but bad things about Comcast, so I think it's a safe bet to assume that they don't really make decisions rationally.

@flawr He blew my mind with the statement that derivatives are linear transformations/operators. I suddenly understood calculus a little better, especially why you could take the derivative of elements of a sum independently.
Incidentally, I've been trying to think of game mechanics in a more abstract manner lately, and I wonder if there's any possibility that I might be able to find or construct a vector space of game mechanics. One could probably develop some really interesting games that way.

@El'endiaStarman this would be cool
Probably falls under the topic of General Game Playing: en.wikipedia.org/wiki/General_game_playing

I've also been pondering on games where the computer evolves or adapts to your playing style so the challenge constantly, but gradually changes.
What would be even better is if this evolution could include the core game mechanic, so that you could be playing a totally different game a week later or something.

I think GGP could make for a cool KOTH, but it might be hard to secretly organize a dozen or so games for the entrants to play.
If we had a random game generator, then such a competition could be feasible. It's just a matter of having the generator be complex/holistic(?) enough that the competitors can't easily take advantage of it.
It might be more feasible/interesting if we limited it to specific categories of game, though, like card games / board games / abstract strategy games.

5:23 AM
@AshwinGupta I wouldn't worry about it

@HelkaHomba no? Isn't 22 the default though, so everyone would know which one to hack.

@HelkaHomba interseting.
Well maybe I should undo my changes...
:P

Right but your pi is not a prime target for hacking unless you are using it to manage offshore bank accounts or something

Its not exactly strong, but I'll come up w/ a better one later. (Guilty confession on stupid password)

5:27 AM
Tbh I don't know a lot about ssh or hacking. I just figure if 22 is good enough for millions of businesses and other personal users it's probably good enough for me.

@HelkaHomba yup, I'd agree.
Well, I've got it working on another port now, I think I'll leave it for the time being.
I'ts too much work to change it. Plus I don't know any Linux (one of the reason's I've got it) so I have been doing a ton of cut/paste

LOL, easy job.

6:24 AM
@BetaDecay I don't think you need a rigorous definition of natural number or integer; N = {0, 1, 2, …} and Z = {…, -2, -1, 0, 1, 2, …} should do.

Oh, okay that sounds easier

If anything, you should mention what P is: precisely those elements of P that has exactly two divisors in N.
Um, 3.333333333333 and 10/3 are not the same number.
Also, 10 decimal places after the comma are going to be a huge pain once the number gets big enough.

Argh how do I use PHP to make a common header bar thingo

Then how do I do it

Why not `header.html`?

You can put whatever html stuff you want before and after the PHP tag

And thx @Betseg

After 5 minutes of googling i think you can't include html

Wot doesn't work...

.php or .html?

.htaccess needs some things too, says the answer in SO

both

<body>
<div id="mainbody">
<h1 class="title">Logicode</h1>
<h3>Welcome to the Logicode Documentation.</h3>
</div>
</body>

</html>```
(That's `title.html`)
```    <html>

<body>
<p>Hello, World!</p>
</body>
</html>```
And that's `header.php`

Do just `<p>Hello</p>`

8:49 AM
Still borked
Halp
They're in the same folder, if it helps

Try <?php echo "<p>hi</p>"; ?>

title.html should be title.php I think

Yeah and that too

Yeah, that works
But the rest doesn't

Do it then
Don't search for logic in php

9:17 AM
So how am I meant to include the whole file

That's a cool realization, isn't it? Then you should also look into the small but beautiful topic of the ring power series over a field (denoted by F[[X]], similarly to the polynomial ring F[X]). This forms a *discrete valuation ring* and there are very nice (and easy to understand) proofs about when a powerseries is (multiplicatively) invertible, or even invertible with regard to composition. And what the ideals look like etc.

This is a little bit more general than the polynomials but also gives some great insights! (Insights into calculus, but also into the beautiful properties of this r
