In Response to My first impressions of Web3
This a response to Moxie Marlinspike’s “My First Impression of Web3” Both gave me a feeling for how the space works. To be clear, there is nothing particularly “distributed” about the apps themselves: they’re just normal react websites. The “distributedness” refers to where the state and the logic/

My First Impressions of Web3
Despite considering myself a cryptographer, I have not found myself particularly drawn to “crypto.” I don’t think I’ve ever actually said the words “get off my lawn,” but I’m much more likely to click on Pepperidge Farm Remembers flavored memes about how “crypto” used to mean “cryptography” than ...

Unidentified PC DOS 1.1 Boot Sector Junk Identified
Anyone trying to disassemble the PC DOS 1.1 boot sector soon notices that at offsets 1A3h through 1BEh there is a byte sequence that just does not belong. It appears to be a fragment of code, but it has no purpose in the boot sector and is never executed. So why is the sequence of junk bytes there, and where did it…

Look How Big Is My Team
I'm used to getting asked how many employees work at my startup. For most people, it's a quick way to assess a startup's success. Supposedly, the bigger, the better. But does it really reflect success?

A/B test improved your website's conversion rate? Not so fast
Many internet companies use A/B testing to evaluate the performance of website changes they want to make. A typical metric in such scenarios is the conversion rate (CVR) of a user, i.e. the probability that a user converts (e.g. makes a purchase) on the website. A typical A/B test setup in such a situation would…

Washed Up
Even if every technology jockeying for a spot under the 'web3' banner evolves beyond proof-of-work blockchains, these systems will still not be part of the web because they designed not to be. 'web3' ain't the web, and VCs talking their own book don't get the last word, no matter how much dirty money they throw at it.
