erickerr··on Launch HN: A0.dev (YC W25) – React Native App Generator
Opening this on desktop.. I'm not reading any of this.

Glancing in more I see react-native mentioned, and expo+expo go mentioned, but like... it's been proven time and time again that Hacker News isn't your ideal feedback loop (ie: Dropbox, AirBNB).

Why make 4 paragraphs of text when you could just say:

- We obliterated X problem: (link)

- We demonstrate why that problem is significant here: (public link or private deck)

- We are growing at X->(timeframe or whatever impressive metric)

Reach out if interested. Thanks. [contact@info.com]

https://secondmeasure.com is like "counting cars in parking lots" on steroids.
erickerr··on Genetic Algorithms in Multivariate Email Optimization
This has a really good overview of the Multi-Armed bandit approach as it applies to testing and optimizations https://support.google.com/analytics/answer/2844870?hl=en
erickerr··on Genetic Algorithms in Multivariate Email Optimization
However with the Multi-armed bandit approach it does make sense to re-consider that since it's a continuous optimization problem and the overall average conversion rate would be higher.
erickerr··on Genetic Algorithms in Multivariate Email Optimization
Thanks a lot for the feedback. This is a first pass implementation, but I agree that more thought should be put into the cutoff threshold, specifically for when there are only initially 2 (or maybe 3) variations.

We considered a weighted decision approach but 1) were turned off by posts like http://visualwebsiteoptimizer.com/split-testing-blog/multi-a... and 2) wanted to keep moving parts to a minimum for V1.

Any thoughts?

erickerr··on BitBar by Grouper - Buy drinks with bitcoin at bars in 23 US cities
I replied with feedback on twitter.

Interacting with the map should hide the top and make the only thing scrollable in the viewport the map (with the "Your Alias" bar fixed at the top). Scrolling down causes you to zoom out when your mouse is over the map, which is a really bad experience.

When you scroll down, maybe the "Your Alias" bar has the BitBar logo on the left, and a metro-picker dropdown on the right. This would make the usability a lot cleaner, because it's hard to zoom into a city if you accidentally click on a bar, which slides up the Drink Picker.

There should also be a "Cancel" on the Drink Picker, that doesn't require you to click on the map, because clicking on the map puts the body scrollTop to 0.

erickerr··on Where'd The Water Go? Google Maps Water Pixel Detection With Canvas
There is a performance hit for this. Rendering the 40 markers in the provided demo takes roughly 7ms on my machine vs 25ms for the fake lake method.
erickerr··on Where'd The Water Go? Google Maps Water Pixel Detection With Canvas
The map, business logo, and people icons just help illustrate the feature. Volume and other value related benefits are communicated elsewhere in the page content, but aren't really additive to the blog post.
erickerr··on A News Feed for your site's Google Analytics
Yes, as I mentioned you have to actively go through and set that up which few take the time to do. It doesn't "just work".
erickerr··on Ask HN: What is your programming music?
The Album Leaf - their entire discography.

It's all instrumental and is somewhere in between Explosions in The Sky and Boards of Canada.

That's a reference to a previous satirical service we made, http://itsthisforthat.com

We created a similar service, http://hackerfollow.com
erickerr··on Tell HN: What's your Tumblr blog?
Completely unrelated to tech - photography and music I find interesting.

Everyone follows PG so the first thing you see isn't empty and discouraging

This already works though it isn't mentioned anywhere yet:

We're not creating another identity for you. There aren't any profiles, it's simply a utility. I agree the messaging could be cleaner and I'll rework some of it when I have time later today, but we dont really need your email or a password for anything so there's little reason to require it other than being the norm.
erickerr··on HackerFollow: Follow HN Users
It's part of the experiment.

More context would be great (browser, page you were on, page you were redirected to). I think I uncovered the problem so you'll need to clear your cookies. Let me know, thanks!

We'd love to do that but the data isn't readily available by scraping. We could continuously fetch the parent_id post until we reach the root story, but that would result in a lot of extra curl requests.. V2 : )
erickerr··on Ask HN: Review My App - TwitBet
Right next to the "Submit" button, it says that the tweet will be sent out. Also, the button itself says "Save and Tweet Your March Madness Bracket"
erickerr··on Ask HN: Review My App - TwitBet
I would agree about needing to have something to show people - what do you think would encourage people to return?
erickerr··on Ask HN: Review My App - TwitBet
I built this service in about a week as a full time student. The $5k prize is guaranteed if 5,000 people fill out the 1st page of the survey.

I'd greatly appreciate any feedback on the product as a whole and if you think a Twitter-based system could do well as a generic sports betting/following platform.

Thanks!

erickerr··on Is porn good for us?
"As the use of porn increases, the rate of sex crimes goes down"

This is a perfect application of "Correlation does not imply causation". It's very likely that over time (during which internet porn has skyrocketed and made consumption frictionless) the awareness for supporting victims of sexual assault as also gone up.. from completely unrelated trends like rises in feminism and an overall decrease in crime over the last 15 years.

erickerr··on Browsarity (YC W10) Allows You To Donate Affiliate Fees To Charity
While I did make and launch http://browseforacause.com a few months ago (which this may or may not have been inspired from), I welcome this launching - any innovation to donate more money to charity can really only be a good thing.
erickerr··on Facebook makes HipHop for PHP open source
They probably just use a python script and type

from php import cppCompiler

not sure why that took 2 years

erickerr··on Did You Mean: Google Maps?
Speed here is a subject of debate. Does Google want to minimize the load time of this particular 404 page (so you can do whatever you're going to do), or do they want to minimize the time to your intended destination? I think it's the later.
erickerr··on Did You Mean: Google Maps?
Good point - this could me mitigated by only returning the results if there are matching Google products
