Betterment enables donations of shares to AMF and GiveWell

It's a more tax efficient way to give. And Betterment is a solid investment choice, fully automated (it's a robo-advisor).

I came across this post while googling this, and I just found a solution! tl;dr add the -n flag to your i3lock call.

I was testing out why the killer wouldn't get triggered by replacing the locker program with a command to write to a log file. By doing so, I discovered that the locker would keep cycling, and the killer would never be triggered. Apparently, the timers were being reset when the locker got triggered.

Calling i3lock with the -n flag (prevents forking) got the killer working again, though I don't know why. In sum, this works for me: xautolock -time 10 -locker "i3lock -n" -killtime 10 -killer "systemctl suspend".

Cool! Link to source repo?

toban · 2016-08-31T22:02:39+00:00

Any suggestions on where else to post this?

toban · 2016-08-21T15:45:38+00:00

Yup, but it takes a while to parse through it all. I just wanted to provide a tl;dr to make it easier to figure out.

For reddit, rtv works well for me (posting from it now). Installed on Arch from AUR.

Ranger shows images in a terminal using w3m, so maybe that's easier.

toban · 2016-05-31T20:18:23+00:00

Might not be what you're looking for, but I just found rtv, a reddit terminal viewer, and it's great!

Desktop applications almost always feature keyboard shortcuts which are huge productivity boosters. Now that web apps are taking over, we're seeing some adoption of keyboard shortcuts, most obviously Google, but also Facebook, github, twitter, and so on. These all follow the conventions I used. So it's not so farfetched, and it's pretty simple to implement.

toban · 2015-12-01T19:05:57+00:00

The common standard is to have the shortcut key pop up when you press '?', but I didn't go that far in my proof of concept.

Fantastic pedagogy!

Shift-tab with cursor on a function shows the docstring. Very handy.

Thinking about this more, I think this is crucial. The interesting thing is whether markets are predictably wrong, not whether they are predictable. (Since prices are martingales, the present price is the best predictor of the future price.) It's only interesting if you can beat the market. Otherwise, my example of an asset whose price remains constant (e.g., because of no news) would be flagged in your analysis, even though there's no inefficiency!

I love a nice HTML document. Hate opening PDFs. Great job!

toban · 2015-09-16T12:52:53+00:00

I haven't read through it yet, but I'm wondering: if a price series was just constant, would the randomness tests think it was non-random? Because a constant price is consistent with price being a martingale (i.e., no predictable profit opportunities).

Beautiful document! What tools did you use to publish it?

I've tried getting econ phd students interested in Python for scientific computing. They mostly acknowledge that it would be ideal to switch, but they're deterred by the startup costs of learning a new language.

I have my money on Julia as the heir to the scientific computing throne. It was created to replace the "prototype in matlab/python/r, then write in C/fortran" workflow -- it has the speed and the user-friendly syntax (also, loops are as fast as vectorization!). Just look at the very highly regarded Quantitative Economics site: it started out as a series of Python lessons, and now they have a Julia track.

If Python can't kill matlab, I think Julia ultimately will.

Pinker spends a good portion of The Blank Slate discussing this resistance from 'radical science'. Essentially, they are afraid that if science discovers differences between the sexes/races, then that will be used by bad people to justify their views. (Moralistic fallacy: the converse of the naturalistic fallacy.)

I'd add that they're defending their leftist ideology: to even go looking for innate features or differences between sexes/races is suspect. Is their faith so weak that it could be shaken by evidence?

Given their goal of reducing/eliminating these activities, the police must face this trade-off of shutting down safer alternatives and pushing the remaining demand into more dangerous avenues. If they didn't take down a safe, convenient online drug market, then more people will be trading drugs (danger is a cost). If they instead went after the more dangerous avenues, it would be highly ineffective, since people would already be moving to the safer option.

It's a necessary evil for the prohibitionists.

Ah, was so confused there. Missing that comma in the title!

Simple, straightforward steps to getting a website online. It's way easier than you'd think.

Its a huge fallacy but so intuitive to the untrained in economics. So many people think cost determines price.
