GavinB··on Bayes's Theorem: What's the Big Deal?
This headline does not reflect the article and is needlessly inflammatory. This article is an explanation of Bayes theorem and overall very positive of it. The "used wrongly" quote is just stating that it's not immune to biases and error. Pretty much any tool "used wrongly" can cause errors.

(In case it's changed, the headline currently reads "Bayes theorem used wrongly, can promote superstition and pseudoscience")

GavinB··on New Tricks for Browser Fingerprinting [pdf]
We've got hellbanning. It helps but they figure it out pretty quickly, especially in chat. I run a kids site, so we have to be pretty draconian about keeping out bad actors.
GavinB··on New Tricks for Browser Fingerprinting [pdf]
Are there any good services or packages for doing this, especially for RoR? I don't need it for advertising, but for banning abusive users who are able to evade the usual means of detection.
GavinB··on A web-reading bot made millions on the options market
It's also possible that an insider knew the news was about to break and waited for the announcement with the trade queued up.
GavinB··on Groot Programming Language
I would think "We are Groot" would be better as the command to accept one byte of input.
GavinB··on Show HN: I built an Android game after work with a friend in 6 months
"90 seconds" may be the best sounding alternative.
GavinB··on Tilde.Club: I had a couple drinks and woke up with 1,000 nerds
This is common usage. I couldn't begin to tell you if it's "correct" or not.
GavinB··on Panda 4.0: Why eBay lost many of its organic rankings
It's possible that Amazon's analytics demonstrate that you're more likely to purchase if shown a wider variety of products, even if you attempted to narrow it down.

Not that their short term bottom line is a worthy excuse for deceptive and confusing search practices.

GavinB··on Is Consciousness Computable?
There's no way to create that book without doing the calculations from each tick to the next. So when you put it into the computer, it's just repeating the calculations done the first time in the creation of the book.

I do think your broader point about the importance computation is correct nonetheless. Though it gets more confusing when you start thinking about what computation actually is, or about the possibility of Boltzmann brains ( http://en.wikipedia.org/wiki/Boltzmann_brain )

GavinB··on Ask HN: Idea Sunday
A service that sits between my bank account and subscription services that only accepts charges that I've preapproved.

This would let me keep track of the services that I have so I don't end up with subscriptions to sites or services that I've forgotten about. It would also let me revoke permission to charge the account at any time. No need to cancel a card if one won't cancel or changes the fees--you just revoke their permission individually.

GavinB··on Show HN: Standing Queries about the World
Publicity teams would absolutely pay for a "Google Alerts but Way Better" product. You'd need to make it much better and easier to use, and have features similar to the peak tracking so that they can get a sense of how popular a certain word is.

They would probably also like to have tweets and blogs from accounts with higher follower counts, pagerank, etc prioritized. So if you get a tweet from an industry leader, you get a text immediately. If you get one from a new account with 4 followers, it gets folded into the daily report as a statistic.

Your point of differentiation would be a "secret sauce" of presenting only the most important information to users and not bothering them with all of the irrelevant ones.

Publicity teams are generally quite free with the company card, so I'd suggest a freemium offering but with a very limited basic plan. And you don't need to worry about them creating multiple accounts because publicity folks don't have the time or knowhow for that.

edit: Drop me a line if you're building something that would work for non-tech savvy publicity folks and need beta users.

GavinB··on Strange light on Mars
With such a thin atmosphere, why would a light shining upwards be visible from the side? For a light to be visible laterally like this, you'd need atmosphere for a scattering effect and a very bright light. A light pointing upwards from the surface of Mars should only be visible to something looking downwards.

Concluding that it's intelligent life "using lights as we do" is just a wild claim with no backing. From the evidence it's pretty obvious that it's a holographic projection sent backwards in time from humans in the future.

GavinB··on Dead Man's Switch
Encrypt what you put behind the Dead Man's Switch, and then give the recipient/heir the key. If you want to get fancy, break the key up into two or more parts and split them among your heirs.
GavinB··on Mozilla and Unity Bring Unity Game Engine to WebGL
This is HUGE news if it performs as well as advertised. We have been creating games in Unity for a couple years and eyeing HTML5 as a possibility that just was never capable enough to trust with a major project.

Unity as a development platform is a joy to use, and now we won't have to have the same "Unity plugin or messy HTML5 game?" conversation for every new project.

GavinB··on Bizarre Shadowy Paper-Based Payment System Being Rolled Out Worldwide
Criticisms like "perfect for criminals" and "no consumer protection" do make sense. Cash is great for money laundering and has no reversibility. The whole point is that these weaknesses are 100% real--and yet not necessarily a barrier to adoption or successful use.
GavinB··on By The Time You Give Them a Raise, They’re Already Out The Door
Recruiters certainly have a conflict of interest.

It would be pretty straightforward to add a couple questions to any general survey of employees in an industry to figure it out.

GavinB··on By The Time You Give Them a Raise, They’re Already Out The Door
I've seen this claim over and over, but never any sort of citation or numbers. Lots of people get competitive offers, get a counteroffer, and then stay for years. I know a number of them personally.

The reason it seems like they never stay is that they don't talk about the offer they didn't accept. The negotiation happens over the course of a few days, and they don't mention it to the other employees. So there's a big bias in how frequently you hear about the negotiation. Whereas if they leave for another company, of course everyone knows about it.

GavinB··on SolarCoin cryptocurrency pays you to go green
Making a monetary system function is important work. From the Federal Reserve chairman to the sysadmins running wire transfer servers to the crew running the printing presses to the security guards who transport cash, there's a huge amount of work involved in running current fiat money systems.

You can dislike cryptocurrencies for all sorts of other reasons, but that fact that some resources are consumed to keep it running really is going to be a feature of any sort of monetary system.

GavinB··on Wanker
Pretty funny, but one second is far too short. This triggers even on a normal resizing. It should only trigger if someone is messing around for a few seconds. It's not much of an easter egg if anyone resizing their window gets it!
GavinB··on One new HTML5 game per week
Subscribed and will definitely be following you. Our game team is exploring HTML5 games and I'm very interested to see where this takes you.
GavinB··on Ethereum is a next-generation cryptocurrency platform
If the devs are reading--the quotes scroll too quickly to comfortably read, especially with no way to control them or go back. Otherwise this is a gorgeously designed site.
GavinB··on One new HTML5 game per week
Game #5 could easily make a nice iOS game. Make it free and IAP for additional puzzles. You'd just need to generate a whole mess more puzzles. Two little bits of feedback:

1. When one of the pieces goes off the screen, you should automatically restart, or at least let the player know they've failed. The first time this happened I wasn't immediately sure what to do--even though it was obvious after a couple seconds. Even once I knew, it was annoying to have to press restart when I'd obviously lost. Auto-restart will make players less likely to quit in frustration.

2. The "locked into place" pieces should have their design more differentiated from the moveable pieces--remove the arrows, for instance. This will help with clarity as levels get more and more complicated.

GavinB··on Magnus Carlsen is World Chess Champion
Since computers play chess (better than humans) by looking at moves and ranking them as advantageous or disadvantageous, I would think it would be relatively straightforward to use a computer to decide whether a move is a mistake or not.
GavinB··on If Your Business Uses Rails 2.3 You Need To Move To A Supported Option ASAP
Did you consider this as a potential business opportunity for yourself? My reaction on reading this was that someone should be giving you either cash or equity for your roles as both an evangelist and the person who realized this was going to be needed and organized it.
GavinB··on Detroit's Decaying Old Train Station Has 5 New Windows and No One Knows Why
Simplest explanation: The owners had them installed to test different contractors, designs, and/or materials. Wouldn't you have someone put a few in before you signed a contract to put them all up?
GavinB··on How to Negotiate a Job Offer
I'd say name a number or range 15-25% above the offer. Or even just "I was hoping for 15-20% more." Thanks, I'll add this.

The point is just to ask for what you want. Often people will give it to you just for asking. It took me a long time to figure this out!

GavinB··on How to Negotiate a Job Offer
The "Pre-Reqs" piece is not right. You really don't need to have another job offer or a current job to negotiate. A while ago I wrote up this script for how to negotiate a job offer with no leverage at all when you intend to accept it no matter what: http://bit.ly/1185CGm

Most job offers come with leeway for negotiation, regardless of your situation. All you really have to do is ask.

GavinB··on The Cord-Cutting Fantasy
The numbers here don't make sense. Most people are paying $50 per month for cable, which supports the current industry. If they all switch to paying ~$50 per month in a different model (whatever it is), an industry of the same size will be supported.

The subscription "all you can eat" model is great. The thing that needs to change from current cable is that I should be able to watch it wherever and whenever I want (and pay not to have ads). The issue right now is that the contractual relationships are so complex that no one is able to cut through the mess to put together the right offering.

GavinB··on “Right click and save as” needs to go away
For everyone complaining that they don't want to be forced to download--just have two buttons:

March Invoice: View - Download

This is much clearer for the average user than a single link with hidden right click functionality. Currently clicking on a link you have no idea what you're going to get.

GavinB··on The StarCraft path-finding hack
Is changing the behavior of a group of units because it happens to be grouped with a distant unit really a good thing for the game?

It makes for a good story, and it's great fun for the person who discovers it. Players like it, because it lets them beat new players even more easily. But players don't always know what's best for them.

This is why Starcraft 2 multiplayer is structured to force players to play on complicated, resource balanced Blizzard approved maps. Starcraft 1 allowed ranked games on any map, and players largely played simplified, resource-soaked maps. Or played nothing but Big Game Hunters and Lost Temple. This was what players thought they wanted, but it wasn't what was best for the game.
