I came across a pretty astounding article the other day. The author of the article conducted a survey, asking a panel of 2,000 Americans familiar with cryptocurrency what impact they believe Bitcoin has on the environment and climate change. The results were as follows:
- 6% said
It is a significant threat to the environment and climate change.
- 26% said
It has a slight impact on the environment and climate change, but not enough to cause a threat.
- 32% said
It has no impact on the environment and climate change.
- 26% said
It is good for the environment.
For those of you keeping score at home, that's a total of 58% of respondents who believe that crypto is either a neutral or a positive influence on the environment. It's hard to believe that this could be the case when some scientists warn that Bitcoin alone could produce enough emissions to push us past the 2°C global warming mark by 2032. I think that the scale and urgency of the climate risks of cryptocurrencies are often misinterpreted when presented at an aggregate level, so I set out to compile some statistics on how to view crypto consumption through the lens of the household and marginal consumption.

If you're on this page, it might be because you received an email I sent that had a file attached with the extension
.asc. The file is a cryptographic signature, which you can use to verify that the email is actually sent from me, and that no one has tampered with or altered any of the other attachments to the email. By default, I GPG sign all emails that I send which contain other attachments. The easiest way to verify that the signature matches my public key is to use a mail client that supports GPG functionality natively. I use a terminal-based mail client called mutt, but I can also recommend Thunderbird, a full-featured graphical mail client from Mozilla. Once you have your client set up, you will need to import my public key so that your mail client knows what a signature from me is supposed to look like. My public keys are hosted on my website, available at this link.

Git allows you to sign commits using a GPG key, as a way to prove that a commit that looks like it was made by you was in fact made by you. Perusers of the git history can the verify the signature by running
git log --show-signatures. On Github, it's even easier to verify, as Github will add a green "Verified" stamp next to the commit, giving a quick visual indication that the signature came from a GPG key that you have asserted as your own in the Github settings. You can view the signing history for the git repository of this website here.
By default, Github will add that stamp to verified commits, and leave any commits that were not signed without a stamp. However, it's possible to activate "Vigilant mode" in the GPG settings of Github, in which case any unsigned commit is flagged with a yellow "Unverified" stamp. Since I'm planning on signing all my commits going forward, I've enabled vigilant mode on my account, but now I'm faced with the eyesore of seeing yellow stamps next to all the commits I made in my
halcyon pre-GPG days. This can not stand.

Over the last few weeks, I've fallen down the GnuPG rabbit-hole. GnuPG, short for "the Gnu Privacy Guard" (long for "GPG"), is a tool for asymmetric encryption, meaning that you can use it to create messages that only a specific recipient is able to read. More concretely, the system relies on private and public keys, where you can use someone's public key to encrypt a message that can only be decrypted with the corresponding private key. Not only have I made my own keys - I have now progressed to the stage where my emails, address book, calendar and passwords are all secured by a GnuPG foundation, with my private keys stored on a tiny device that I can carry with me. Bad idea? Maybe. Totally awesome? Abso-fricking-lutely!

Lately, I've been trying to disconnect from technology in my spare time (more on that soon), and I've found myself reading more as a consequence. One of my favorite literary discoveries of the year is Mary Oliver, the late, great American poet.
Oliver's poetry is hauntingly beautiful, but also very accessible for poetry novices such as myself. A few weeks ago, I took a library copy of Oliver's Pulitzer-winning volume of poetry American Primitive along for a walk in Central Park and ended up finishing it in a single sitting, shaded from the summer sun by a tulip-tree.
Since I don't have any content yet on this website, I share two of my favorite Oliver poems below. Enjoy!

Hi, and welcome to my website. Yesterday I received an email from my domain provider that this domain will auto-renew in a week, meaning that I've been sitting on this domain without publishing something for close to a year - time to change that!
In the future, I will post some thoughts here about various things that interest me, including finance, the attention economy, etymology and technology. For now, I've contented myself with creating some basic CSS styling to provide a hopefully pleasant reading experience.
Thanks for stopping by, and feel free to contact me through the email link in the footer!
