I’ve been reading Joseph Mitchell’s Up In the Old Hotel, a fascinating collection of writings from the first half of the 20th century about New York street characters by one of the New Yorker Magazine’s most famous and eccentric contributors. If you haven’t read it, and you have a deep interest in the history of New York City, I highly recommend it.
The other day I had an informal talk with a friend about a project we had been offered. I can’t divulge much about the project but I can say that it has, structurally, a lot in common with an ecommerce app. Users shop a class of product and check out. Work has already been done on this app. The “MVP” that has been built has a wholly decoupled “thick client” browser-based UI built in AngularJS. I have a decent amount of experience with AngularJS as well as the other, similarly popular (possibly moreso) javascript MVC framework Ember.js.
I have seen a trend firsthand in the last several projects I have been offered – and a couple that I have taken on – toward the use of these javascript frameworks and decoupled, thick client architectures. Stunningly, in every one of these cases, the architecture is unambiguously more burden than benefit (much more, in fact) in respect of both development load and user experience.
I was walking down to my favorite neighborhood coffee shop, Porto Rico, this lazy Sunday afternoon to get a coffee when I passed by Tom Preston-Werner of Github and Gravatar fame having coffee at another neighborhood spot with his wife, Theresa. I did not wish to intrude but also felt I couldn’t let the moment pass without just making a momentary show of gratitude. To my shock he ended up asking all about my own work and we talked for several minutes about Github, Jekyll and many other things.
Rails 4 nudges developers toward more pervasive use of fragment caching (and the so-called “russian doll caching” strategy of deeply nesting fragment caches) with the introduction of ActionView::Digestor and on-by-default appending of template digests to fragment cache keys. Though actually pretty simple in its implementation, this feature (paired with correct use of ActiveRecord’s “touch” relation option) solves most of the formerly enormous headaches you’d encounter (and still do today with pretty much every other framework) trying to implement an advanced caching strategy with largely dynamic content. I’ve been working with this technique for more than half a year now (initially using the Rails 3 “cache_digests” gem , which implemented the same functionality now available through ActionView::Digestor in Rails 4).
Since we now know that we can’t reasonably expect the emails we exchange with friends and colleagues to not be warehoused and read without our knowledge (and without a subpoena, warrant, or similar from the reading party), I want to shine a spotlight on one of the still-effective techniques available for restoring some privacy (with caveats) to personal email. This strategy is not new. In fact, it’s quite old. I’m talking about GnuGP(GPG), a FOSS implementation of the OpenPGP encryption standard, and GPGMail, an awesome plugin for the native Mac Mail client.
Digital Ocean is a relatively young VPS provider with servers in New York, the Netherlands and San Francisco. My first introduction to them was working on a web app called RapPad which helps people write and share rap lyrics and which I started contributing to a few months ago after it caught my eye on Hacker News.
RapPad’s owner, Amir, had it up on a VPS with Digital Ocean, which I was only vaguely aware of. I was pretty blown away with the slickness of our deploys (typical Rails deployment bottlenecks like asset compilation were carried out with literally 4x the speed of on my EC2 instance) and the speed with which I could traverse the file system, install packages and do various administrative tasks.
A friend of mine told me a few weeks ago that he thought he’d seen me on a banner ad for the software freelancing site GroupTalent. He took a screencap and I confirmed it was, indeed, me. Today, I followed a link from a news aggregator to TechCrunch and, lo and behold, I saw my likeness! I took a screenshot, too.
Hi, my name is Nicholas and Hacker Notes is my personal blog. It is a collection of practical things I’ve picked up through my work in software, as well as writings on other subjects like travel, art and life in New York. You can read more about the site and me by clicking here
