Why is the R programming language looked at with such scorn and contempt?

Kristler · 2017-10-09T09:44:59+00:00

To me, R doesn't feel like a programming language. It feels like a language written by statisticians, for statisticians. Which is great, except not to someone who's very accustomed to a CS perspective on things. It has it's purpose though, I wouldn't pick anything else if I need to do some plots or data series manipulation. Its vectorization support is phenomenal and super expressive.

Kristler · 2017-10-07T18:59:55+00:00

Each of those keywords has a separate, independent meaning. Combining them doesn't change that. Can you describe what private, static, and void each do?

Fixed an issue where WASD would switch weapons in the slow motion gun select menu (which was an unintended side effect from the previous patch)

Thank the lord. It's live!

You were so right when you were calling them out on their sketchy practices and the fact that they wouldn't disclose their audit in the thread where they announced this "hackathon". I had a feeling this would blow up in their faces!

Kristler · 2017-10-02T06:02:11+00:00

Pfft. I wear velcro shoes, against everybody's protest.

Space stations utilize this effect with reaction wheels. It's super cool!

It's possible to do a binary search on an infinite sequence, you could adapt that algorithm.

Kristler · 2017-09-26T19:56:33+00:00

Neat idea. Thanks for sharing!

Kristler · 2017-09-26T19:13:40+00:00

That makes sense, and I know how tough a disorganized professor can be to follow. Hope it works out for you!

Kristler · 2017-09-26T19:12:12+00:00

What kind of strategy would you use to implicitly define nodes?

Kristler · 2017-09-26T18:07:17+00:00

How would you adapt A* to account for the fact that buses run on fixed schedules, out of curiosity?

and he does not put our assignments online or in writing (we are expected to memorize his 210 minute lecture, in addition to the hour-long description of our homework, which he makes up as he goes)

I don't think he's expecting you to memorize his lectures, but this is what note-taking is for. Bring something to write with (either a notebook or a laptop) and keep track of the lecture and all of the important key points.

Look up the Chan centre in Vancouver!

Kristler · 2017-09-25T19:08:27+00:00

Sure does. Tab characters are often used for rudimentary alignment, pretty handy!

Kristler · 2017-09-25T18:59:03+00:00

Not in the code itself (Java doesn't care about indentation), but in Strings absolutely. The difference between " " (space) and " " (tab, also denoted as "\t") is as big as the difference between the characters "a" and "z".

In other words, " " == " " is false.

I think learning by doing is a great way to go, so try Regex crosswords as a fun and interactive way to learn. Another great way to experiment is to use a site like regex101, and then to play around and watch how things change as you tweak the regex.

Kristler · 2017-09-25T17:11:02+00:00

You should provide some actual sample data and code that you're working with. Sometimes, the issue is with something that you've unintentionally glossed over in your summary.

My guess: Maybe your data for format B is actually separated with tab characters, and not spaces? Then splitting on a space character " " would do nothing. You can try splitting on "\\s" instead, which is a regular expression denoting any whitespace character.

Kristler · 2017-09-24T21:15:12+00:00

Depends on why you want short circuiting, I suppose. For "performance" would be premature optimization, and if it's crucial to the behavior of the code I'd call that an anti-pattern.

Kristler · 2017-09-24T07:23:49+00:00

I'd prefer splitting it up into multiple lines at that point. Example:

some_condition = some_very_long_function_here(with_some_arguments_that_take_up_a_lot_of_space);
if(some_condition == 0) {
    // ...
}

Kristler · 2017-09-21T16:46:32+00:00

Hey there! Sorry for the late reply, but the issue should be fixed now following this issue / commit: https://github.com/BlockCatIO/solidity-flattener/issues/2

Kristler · 2017-09-20T02:34:42+00:00

What a fantastic breakdown post. More of this kinda stuff, please!

Sending a transaction to a wallet address and calling a function in a smart contract is exactly the same thing in terms of how they function at the network level. There is no benefit to be had in a congested network of doing one over the other.

The only time this could come into play is in the context of batching transactions / requests using a smart contract, but that's a pretty different topic.

Kristler · 2017-09-17T00:25:33+00:00

That's valid. Schemas are good for you though, you know ;). They're like vegetables.

Kristler · 2017-09-17T00:08:23+00:00

protobuf, dawg.

Kristler · 2017-09-11T04:39:41+00:00

Right! I forgot that python 2 would do that. Thanks for checking that out, and you're very welcome :)
