There's a fantastic Planet Money episode about the Universal Postal Union[1] and why this is a problem. Basically, the UPU assumes that a country will send about the same amount of…

Ruby's standard library does this. Here's the code: https://github.com/ruby/ruby/blob/trunk/lib/set.rb

The zero interest rate definitely does contribute, but a bigger deal for mortgage rates is that the Fed continues to buy $24-26 billion a month in mortgage-backed securities. It is…

Facebook's draft.js[1] tries to solve a lot of these problems and uses React under the hood to maintain a mapping between the model of the document that you are editing and the DOM…

The TSA doesn't use backscatter x-ray machines any more. They were all removed because the company that makes them (Rapiscan) couldn't figure out a way to mask the naked images. No…

Realistically, not much for a while. The FED still doesn't think inflation will hit its target until 2018, so low rates are here for the time being. The two things you might notice…

As a DC resident, this project is really ridiculous for a few reasons. First of all, it is no faster than a bus because it still does not have a dedicated right-of-way. It also fol…

One of the biggest advantages that I know of is that VSC has a very good NodeJS debugger for Javascript and Typescript[1]. Having the debugger integrated into the editor is huge im…

I was a little disappointed about this too. It could be that their distribution center is close to BWI, and traffic between BWI and DC is epically bad during rush hour. Many of my …

This is great. I think the option to revert to a perpetual license will be a nice amount of market discipline for the team and keep them from stagnating. I actually appreciate the …

These types of bonds do exist. They are called "linkers" and many governments issue them. In the US, we have TIPS (Treasury Inflation Protected Securities) and some savings bonds t…

Hey antigen8, I am working on something very similar with a non-profit in NYC, for NYC schools. It's very exciting, we are building on NodeJS and MongoDB, and already have some dat…

The title about 'warning Washington' is almost certainly a heads up and not a threat. The Treasury needs to understand market dynamics to have smooth auctions for new treasuries, w…

It's extremely likely to pass. Since this isn't technically a "treaty", Congress can only pass a bill to disapprove of it [1]. Obama can then veto the disapproval, and there are en…

How did you guys drop down to a read-only connection on Heroku Postgres? We directly connect DB clients like PGAdmin to a reporting DB on Heroku, but Heroku only seems to support c…

Two things I've done: 1. Try your best to move more during the day. Standing desks can help, but standing for 6-8 hours is probably just as bad as sitting. Do walking meetings if p…

The Fed also releases all of the memos that are used by the FOMC to set monetary policy. It just releases them with a five year lag. It also releases transcripts of all FOMC meetin…

(Disclaimer: IANAL) Reading through the history of the case[1], it looks like the District Court ruled that the Federal TSA officers involved were entitled to qualified immunity un…

This is pretty bad, but I believe it is only possible to get an access token if you also allow malicious/non-trusted users to either create new OAuth client registrations (`Doorkee…

One thing that is interesting is that Congress usually blocks funding for DC laws by restricting how we can spend our local tax dollars (through the appropriations process). When D…

I have had good experience using HDF5 to store time series data, but just research datasets and nothing that has been put into production. I don't really know how well it works wit…
