agrona··on Using Git Wrong
The author suggests one "symptom" of using git wrong is

>Have you ever did a code review, and gave feedback that was longer than doing the fix yourself, while you’re at it?

But this seems to neglect the utility of teaching people to do things correctly. Sure, I could always just fix junior programmers' mistakes, but it seems better to educate them in the first place.

Sending the fixes back down doesn't seem like it would have the same impact.

agrona··on How to Report a Bug to Microsoft
The real trick is to know somebody who works on the product. Seems to be the only way I've ever seen any bug get reported and fixed.
agrona··on Twitter refuses US order to disclose owner of anti-Trump account
This is great. Although part of me has a desire for the person to be outed so Trump can lose yet another horrendously baseless first amendment lawsuit.

Hopefully a lot more visibly, this time.

agrona··on “We're considering banning domains that require users to disable ad blockers”
A mod of /r/sports (~6M users? is that right?) said

>Send me your automoderator rule once it's done, we'll add it our sub as well.

Seems likely to spread pretty quickly.

agrona··on GiveDirectly Planning to Give $30M in Basic Income to East Africa
GiveDirectly's previous work involves finding the poorest communities in the world and targeting the poorest members with direct cash transfers. I was turned on to them a few years ago by GiveWell (unrelated), which attempts to evaluate charities based on cost effectiveness and capacity for more funds.

In addition to the GiveWell reports, GiveDirectly also document and publish their work and research. It's exciting to see the impact that they are having (and how minimal the systemic abuse of the money is):

agrona··on Why you shouldn't exercise to lose weight
The article claims that

>We have no control over our basal metabolic rate

and then links to a page[1] that explains

>Muscle cells require more energy to maintain than fat cells, so people with a higher muscle to fat ratio tend to have a higher BMR.

and

>Muscle tissue burns more calories than fat tissue, so increasing your muscle mass will help you lose weight.

It doesn't seem to address this discrepancy, though (that by exercising to build muscle mass one can affect their BMR and thus the lion's share of the calories burned).

agrona··on What Do You Do with 120-Sided Dice?
The mathematical properties of the distribution of the numbers on the sides are very pleasing.

They remind me of the (absolutely fascinating) "Go first" dice[1], any subset of which are guaranteed to produce a perfectly fair ranking.

agrona··on Megagames: Giant board games for hundreds of people in the same room
We'd like to! We're thinking of something this winter, but are taking a much-needed break for a few weeks.

Our first event was a lot of work and these are entirely labors of love--the ticket cost lets us basically break even.

agrona··on Megagames: Giant board games for hundreds of people in the same room
We just ran two events in Seattle.

The "MegaGame Society" is sort of the over-arching organizing group (they licensed Watch the Skies from the UK group, updated it significantly, and are recruiting more groups to run it locally).

They're definitely the folks to follow for information on games outside of the UK.

agrona··on The Case Against Gay Marriage: Top Law Firms Won’t Touch It
Oh I see.

The confusion arises because the antecedent of "it" is unclear.

I read "it" as referring to "gay marriage" and not "the case against gay marriage". How confusing.

agrona··on The Case Against Gay Marriage: Top Law Firms Won’t Touch It
I don't understand the headline. It seems to be saying "Top Law Firms Won't Support Gay Marriage", this is a mark against it.

However, the article seems to be saying the opposite: top law firms are all FOR it, and those opposed don't have top representation.

agrona··on What happens when Betelgeuse explodes?
There's a guide (in development) at eyesonthesky.com[1] aimed at newcomers, who may be using poor telescopes in poor atmospheric and lighting conditions. I've been following it quite successfully from my back yard in Seattle. It focuses on the brightest galaxies and nebulae, interesting clusters, and binary stars.

agrona··on Paper sizes
I went into a Fedex/Kinko's in the US, to try to print something on A3.

They looked at me as if I had just asked them to sell me a unicorn. They then offered to custom cut a piece of paper for what I'd approximate as several tens of thousands of percent markup.

agrona··on Anglo-Saxons did not use the four-letter profanities we credit them with
Sorry to rain on your parade, but þ is a voiceless "th" sound (as in "thing"). Also, that's the part that means "muscle".
agrona··on When a Cartoonist Landed in L.A. County Jail, She Drew What She Saw
The comment you're replying to is word-for-word copied from a highly upvoted comment on reddit yesterday (but is now deleted) by a user with a handle I won't repeat here. [1]

So what you're seeing is cross-pollination. I'm honestly surprised to not see this comment down-voted, as it's pretty impertinent to the conversation and is textbook ad hominem. ("Crazy lady says prisons are terrible: who cares she's crazy").

edit: oh, I see my second paragraph basically did happen already in some flagkilled posts.

agrona··on A Formula for the Number of Days in Each Month

agrona··on NASA: We're sending humans to Mars
The intriguing point to me that I haven't seen addressed on any reporting of the announcement is this:

Is the plan to put humans on the surface and then bring them back home? How do they intend to land and get back off of the planet?

(Forgive me if they addressed this in the video; I haven't had time to watch it yet.)

agrona··on Wanderers: a short film of humanity's expansion into the Solar System [video]
Art and source photos aside, this link is sort of disappointing. For example,

>As Mars' diameter is about half of the Earths, the elevator cable wouldn't have to be as long to reach geostationary orbit and due to the lighter gravitational pull it wouldn't suffer as much stress from its weight.

Mars' diameter has nothing to do with the distance to stationary orbit, which is a result of gravity (and thus its mass).

agrona··on The Unbalanced Design of Super Smash Bros
Dave Sirlin had a recent(ish) post about balance in fighting games here: http://www.sirlin.net/articles/game-balance-and-yomi

He mentions a few different Street Fighters.

agrona··on Mountains on neutron stars
From my reading of it:

>The size of the highest mountain of order ∼ εR can be roughly estimated from the inequality (292).

>P, P˙ and I are, respectively, the pulsar’s period, period derivative and moment of inertia [in inequality (292)].

Those terms are all just multiplied together in the inequality, so changes in any of them could affect epsilon (the "dimensionless parameter characterizing deformations of the star")

agrona··on Good Samaritan Backfire
>Unless it's against some kind of law for someone to observe police, you should know better than that.

What isn't against the law?

This probably doesn't apply exactly, but there are plenty of laws about "disobeying lawful orders of a peace officer".

Here's an example (it may not apply in these case, I dunno, IANAL):

> It is unlawful to willfully fail or refuse to comply with a lawful order, signal, or direction of a peace officer[...] in uniform [...] or to refuse to submit to a lawful inspection pursuant to this code.

CAL. VEH. CODE § 2800

agrona··on The hardest computer game of all time
I had a discussion with the creator about beating the last level. I had a solution that solved 95% of it, but I have no idea if it was close to working. Zachary confessed he hadn't beaten it either, but he did prove that it was possible.

On another note, the histograms you get after beating a level are the best high score screen implementation I have ever seen. I gush over them whenever I get the chance.

agrona··on Can Snowden be targeted using the Adobe breach?
You don't have to blindly trust a third party.

I have a KeePass which can generate random passwords. I trust that because it's open source, so I could look at what they're doing--and build it myself--if I wanted.

I store the db file in Dropbox, but I don't trust them either: my file is encrypted with both a unique password and a second key file which I've taken pains to only ever transmit by copying on removable media.

agrona··on Why Python uses 0-based indexing. It's because of slices
FORTRAN and Algol60 are also not-0-indexed.

From the exple.tive.org page Guido links to:

> On top of that other languages that antedate BCPL and C aren’t zero-indexed. Algol 60 uses one-indexed arrays, and arrays in Fortran are arbitrarily indexed – they’re just a range from X to Y, and X and Y don’t even need to be positive integers.

It was actually a pretty interesting read, I recommend it if you have the time.

agrona··on Pragmatic D Tutorial
Is there some way I can submit corrections? I've found a few typos/grammar mistakes on the first few pages, but can't seem to find any contact information.
agrona··on What is the best comment in source code you have ever encountered? (2011)
Not exactly a comment, but I immediately thought of this:

"Whoa, that’s a full fog all the way. Double fog, oh my god. It’s a double fog, all the way. Whoa that’s so intense. Whoa man! Wow! Whoa! Whoa! Whoa ho ho oh my god! Oh my god! Oh my god! Woo! Oh wow! Woo! Yeah! Oh ho ho! Oh my god! Oh my god look at that! It’s starting even to look like a triple fog! Oh my god it’s full on! Double fog all the way across the sky! Oh my god. Oh my god. Oh god. What does this mean? Oh. Oh my god. Oh. Oh. God. It’s so bright, oh my god it’s so bright and vivid! Oh. Ah! Ah! It’s so beautiful! Oh my god. Oh my god. Oh my god! Oh my god, it’s a double complete fog! Oh right in my map. Oh my god. Oh my god, what does it mean? Tell me. Too much. I don’t know what it means. Oh my god it’s so intense. Oh. Oh. Oh my god." - Change 533404 by jim on 2010/07/19 18:07:00

agrona··on How to Raise Money
Forgive my ignorance, but what does it mean for a founder to be "formidable"?

e.g. in this context:

> The founder who handles fundraising should be the CEO, who should in turn be the most formidable of the founders.

agrona··on Nintendo 2DS
I want to quash this rumor: Nintendo does not require 3rd parties to use particular features (3D screen, waggle, etc.)
