The Cartouche Coaster Collection

I just finished a new art project: Coasters with the cartouches of my favorite pharaohs + the backing digital sketch.

In chronological order:

  • Menes
  • Sneferu
  • Maatkare
  • Akhenaten
  • Ozymandias (Ramesses II)
  • Alexander
  • Ptolemy
  • Cleopatra

A Clojure DSL for Web-Crawling

When building crawlers, most of the effort is expended in guiding them through a website. For example, if we want to crawl all pages and individual posts on this blog, we extract links like so:

  1. Visit current webpage
  2. Extract pagination links
  3. Extract link to each blog post
  4. Enqueue extracted links
  5. Continue

In this blog post, I present a new DSL that allows you to concisely describe this process.

This DSL is now part of this crawler:

A Frame That Listens

The incredibly talented Pem Lasota, Aram Ebtekar and I put together a small project to enhance the music experience in our living room.

What ensued is the first of many projects we plan to roll out - all focused on building the greatest living-room music experience in the world.

The setup involves 4096 LEDs arranged in a matrix, powered by a raspberry pi and a beefy condenser mic. The electronics fit into a 3D printed case. Pem did a significant chunk of this in Solidworks - a piece of software I was extremely impressed with. In one of the sessions, I was able to make reasonable headway with mild supervision. Few pieces of software are this easy to pick up. Solidworks have done a solid job.

The frame listens via the condenser mic and generates beautiful visualizations when it “hears” audio. This is what happens when we blast Pavarotti on our music system:

The Lunacy of The Apple India Story

In India, 30% of goods sold by foreign companies must be manufactured within the country.

This law puts a damper on Apple’s India plans - threatening to prevent them from bringing their incredibly successful retail strategy to the country.

Turns out there’s an exemption for retailers providing cutting-edge technology. Apple apparently failed to qualify for this exemption. This decision is top-level comedy coming from a country that has failed to deliver indoor plumbing to more than half its citizens.

There’s a beautiful anecdote from the 80s or 90s (or some other time the nation was conducting its large-scale economics-voodoo social experiments). Sunil Mittal - founder of Airtel, one of India’s largest telecom companies - saw a push-button phone on a trip in Taiwan and decided to bring it to India - where the rotary dial was still state-of-the-art.

Turns our phone imports were banned. The burgeoning company had to set up operations to buy fully built phones in Taiwan, break them apart, ship them to India, and then reassemble them.

I am sure that this lunacy was fully paid for by the customers.

Sunil himself mentions this story near the 16:25 mark:

If you wondered where to look for a Yakov Smirnoff jokes in a post Soviet world, India’s got your back.

India’s vast bureaucracy is now bringing its finely honed judgement to deal with the world’s most successful companies.

fort-knox: A disk-backed core.cache implementation

core.cache is a small and convenient cache library for clojure. It enables clojure users to quickly roll out caches. In this blog post I am going to describe a clojure implementation which stores cache entries to disk: fort-knox.

In a few recent projects I’ve needed a cache with entries backed to disk. This is a vital requirement in applications that need to be fault-tolerant. LMDB (which I’ve had very positive experiences with) is fast, quick and perfect for this task. fort-knox implements the core.cache spec and stores entries in LMDB. clj-lmdb (subject of a previous blog post) is part of the plan now.

Note that this library deviates slightly from suggestions for core.cache implementations. For instance, the backing store doesn’t implement IPersistentCollection or Associative so fort-knox might deviate from expected behavior. Thus YMMV.

Consuming News: 2016

Quartz has a new news app - an absolute peach.

The NYTimes in comparison is a brain-dump.

As a kid, in the pre-WWW days, people around me consumed news in the following forms (I couldn’t be bothered):

  • 30 minute segments thrice a day on a popular TV network.
  • Newspaper covering stuff from a time-period between last week and 2:00 am this morning.
  • 24 hour news on TV.

The WWW presented a challenge (and still does) for traditional news orgs. I believe all content gets 2 kinds of eyeballs - the kind of folk who are looking for exactly that content and the kind who are bored and will watch whatever is on. When a TV producer sets up a narrative for a day’s worth of programming, you get the attention of both these groups - there are few other options.

In an on-demand world, long-form news that is hastily put together needs to compete with youtube videos, reddit and so on. Converting a narrative of events into a blob of text you can put on your site is going to attract only the kind of people who want to read this sort of stuff in their spare time.

In my experience this species loves the color beige and has the world-view of prep-school headmasters.

And to capture and lock down this audience, you are forced to convert journalism into a weird vaudeville performance. In fact The Daily Show ended up becoming a meta-news org making fun of this phenomenon.

As print journalism and 24 hour news orgs die, I see 2 main vehicles for news consumption emerging:

  • Breaking news outside traditional media cycles - plane crashes, etc. This is stuff that will go viral on social media before a reporter arrives at the site.
  • Breaking news within traditional media cycles. A presidential candidate’s decision to drop out of a race will typically be leaked to the NYTimes or some other established organization.
  • A stream of news delivered thrice a day - possibly personalized since people don’t enjoy their senses being assaulted with information all the time. The new Quartz app (I think) fits this space nicely. The NYTimes has an app called NYTNow but it isn’t clear to me if the feed is personalized at all. Given that the service has a twitter presence, it is entirely possible that there is zero personalization.
  • Long form analysis with amazing visualizations. This sort of stuff requires expertise along several dimensions - something I’ve seen the NYTimes excel at. They produced this brilliant piece on school districts, this exceptional piece on Michael Bloomberg’s tenure as mayor and this beautiful piece on the silk road.

This leaves us with how to make $$.

I don’t think breaking news is a serious vehicle to make money (anymore). However existing media shops need to invest in this space to maintain an aura of legitimacy. This might change in the future but today’s expectations of a news org include breaking news. It might be ok for a newer media org to become purely an analysis-based-reporting organization (like Nate Silver’s, but I would still like the news app to alert me when something serious happens (like the Paris attacks) and not have to discover this on Twitter.

Quartz has been delivering small ads in the news stream that look like this:

I like these sorts of ads - they aren’t intrusive (well, for now) and possibly get you more impressions than whatever the status quo is.

There are 2 additional examples I want to cover. TomoNews is an incredibly creative news org. The animated shorts are rather entertaining.

BuzzFeed has mastered the art of bringing people to their site, creating a stable revenue stream from their baity content and produce some very nice long-form news articles.

To survive, journalism needs to change. There are new gatekeepers, new platforms and new competitors. News needs to change from a brain-dump to a new kind of performance art. Existing media powerhouses have several weapons in their war chest - a brand-name that resonates well, existing relationships with the rich and powerful, and revenue streams (they might be dwindling but at least they’re around).

This soft-power needs to mix with the best photography, web-design, typography and visualization-tech. Each piece of investigative journalism should become a distinct, pleasant memory - like when Walter Cronkite covered the moon landings:

In short, give people something they will enjoy for a reasonable price.
