@LASTEXITshirts Too soon?

This week we build a lightsaber app and revisit the PC XT; Node.js reactions do tumblr dot com; we practice naming things; and learn to not prematurely optimize; let AIs talk amongst themselves; we turn the gears on Ferrero Rocher.

straker/html-tagged-template Proposal to improve the DOM creation API using template literals. I'd love to see this added to the DOM:

Naming Things This is something that happens to me a lot. In the process of trying to figure out better variable/function names, I slowly discover the story behind the code, and then rewrite the code to tell that story. What I end up with is more coherent, easier to read, and often even performs better.

In this example, a big pile of "what does this even do?" turns into an obvious fetchRegisteredUsers().then(updateRegisteredUsersTable) -- you don't need to know JavaScript to figure out what it does.

Why Quantity Should be Your Priority And this applies to code, design, documentation, pretty much everything. Or as my wife says, "I'm not made of magic, I'm made of practice".

Let me elaborate: quantity should be a higher priority than quality, because it leads to higher quality. The shorter path to maximized quality is in maximized quantity, and executing on the feedback after each finished product. (Some may say that this is a less refined form of deliberate practise.)

I no longer understand my PhD dissertation Math, with its single letter variables, terse syntax, and "let's just drop all these steps for brevity" ... not so different from programming after all:

“The result now follows easily…” may have made sense back when, but now the author-turned-confused reader can profess that it most certainly does not follow easily, at least in his own mind.

Codeology Turns your Github projects into 3D ASCII art. This is what Zombie.js looks like.


Write code that is easy to delete, not easy to extend. This. So much this:

To avoid paying for a lot of code, we build reusable software. The problem with code re-use is that it gets in the way of changing your mind later on. ...

To write code that’s easy to delete: repeat yourself to avoid creating dependencies, but don’t repeat yourself to manage them. Layer your code too: build simple-to-use APIs out of simpler-to-implement but clumsy-to-use parts. Split your code: isolate the hard-to-write and the likely-to-change parts from the rest of the code, and each other. ... Don’t try to do all of these things at the same time, and maybe don’t write so much code in the first place.

Should I Optimize? Calculates whether code is worth optimizing, based on your hourly salary and EC2 instance pricing. Tape this to the office wall: "Are you going to save more than 412 hours of instance time?"


Why Do Employers Rarely Offer Explanations to Rejected Candidates? Cue #notallcandidates:

Just know that a big part of the reason why you can't get insight into your interview performance is likely due to the loud, unprofessional, and often vocal minority who have pretty much ruined it for everyone else.


A Conversation Between Two AIs When two AIs try to schedule a meeting for their humans:

As you can see, the AIs communicate with one another in natural language as a lingua franca. It seems — what’s the AI analog of dehumanizing? — for them to have to put up with such a primitive form of communication. But I suppose it what’s they’re stuck with until the singularity.

This week we remove the center line; we find a way to blame others; we struggle to name things; we pick on locking algorithms; we kill some dependencies; the Fitbit pregnancy test; we hack a toilet; the myth of meritocracy; and resistence is futile.

Design Objective

White centre lines are being removed from roads in the UK—for safety No idea why it works, but it does:

The TfL white paper found that drivers tend to slow their driving by up to 4mph on roads with no center lines.


The white paper’s authors admitted that they did not know for sure the exact cause of the slowing traffic, but they suggested that "center lines and hatching can provide a psychological sense of confidence to drivers that no vehicles will encroach on ‘their’ side of the road.”

Yes, you can rely on Amazon’s new game engine during the zombie apocalypse TIL Amazon's new game engine is not a safety-critical system, but may still be used in the event of a Zombie apocalypse:

However, this restriction will not apply in the event of the occurrence (certified by the United States Centers for Disease Control or successor body) of a widespread viral infection transmitted via bites or contact with bodily fluids that causes human corpses to reanimate and seek to consume living human flesh, blood, brain or nerve tissue and is likely to result in the fall of organized civilization.

JavaScript fatigue fatigue We call it "bleeding edge" for a reason. Newer technologies are never mature, you'll spend a lot more time with little progress -- working hard with nothing to show for leads to burn-out -- "JavaScript fatigue" is a choice, and you can easily avoid it:

  • Wait for the critical mass. You can often afford to get started by reading the opinions of people you trust and wait it out until new ideas prove themselves.
  • Stick to things you understand: don’t use more than 1–2 new technologies per project.
  • Do exploratory toy projects: I like creating small projects that explore technologies or aspects of technologies.

How this company tracked 16,000 Iowa caucus-goers via their phones What you buy, where you live, and who you're likely to vote for:

So on the night of the Iowa caucus, Dstillery flagged all the auctions that took place on phones in latitudes and longitudes near caucus locations. It wound up spotting 16,000 devices on caucus night ... It captured those mobile ID’s and then looked up the characteristics associated with those IDs in order to make observations about the kind of people that went to Republican caucus locations (young parents) versus Democrat caucus locations. It drilled down farther (e.g., ‘people who like NASCAR voted for Trump and Clinton’) by looking at which candidate won at a particular caucus location.

Gender bias in open source: Pull request acceptance of women versus men If you've been paying attention, there's nothing surprising about this:

Surprisingly, our results show that women's contributions tend to be accepted more often than men's. However, when a woman's gender is identifiable, they are rejected more often. Our results suggest that although women on GitHub may be more competent overall, bias against them exists nonetheless.

Is this the perfect save icon?

The key thing is, if you really need an icon just make sure that it is simple, identifiable and consistent.

It’s unclear what the future will hold for the floppy disk icon. Maybe there is an argument that you don’t really need to know that it’s a floppy disk at all? You just need to know that pressing this weird boxy symbol means to manually save something.

The Secret UX Issues That Will Make (Or Break) Self-Driving Cars The hardest problem in UX science?

The Price Of Not Using UX Patterns But you already knew that:

When users are accustomed to using a pattern, even a minor change in that pattern can be very expensive in performance terms. In fact, the minor change is confusing in two ways: (1) since the difference is minor, it can go unnoticed, hence , and (2) since the user is already well-trained with the standard pattern, their knowledge masks the new pattern and inhibit learning.

@assaf Existential UI

Tools of the Trade

Spacemacs Emacs for people who love Vim.

tuvistavie/atomic-chrome Use Atom to edit text area in Chrome.

Noun Project for Mac 100,000+ icons in easy to search, minimal app.

The Keybase filesystem Big news for the security minded: frictionless sharing of public signed directories, and sharing private end-to-end encrypted directories:

Every file you write in there is signed. There's no manual signing process, no taring or gzipping, no detached sigs. Instead, everything in this folder appears as plaintext files on everyone's computers. You can even open /keybase/public/yourname in your Finder or Explorer and drag things in.


Soon, you'll be able to throw data into /keybase/private/yourname,pal@twitter, even if that Twitter user hasn't joined Keybase yet. Your app will encrypt just for you and then awake and rekey in the background when that Twitter user joins and announces a key.

A software developer's guide to clean code Great rule for naming things:

The larger the scope, the more important to get the name right. Don't concatenate your variable and function names, you're not going to run out of bytes! But self-describing code is just about understanding the intent. It's also about refactoring and improving your code flow. Imagine if you did a standard "Search & Replace" for all references of variable "x" or even worse "a" or "b". A world of fun awaits as you undo your changes and revert to manually changing all instances of that variable.

The Reductive Seduction of Other People’s Problems

If you’re young, privileged, and interested in creating a life of meaning, of course you’d be attracted to solving problems that seem urgent and readily solvable. Of course you’d want to apply for prestigious fellowships that mark you as an ambitious altruist among your peers. Of course you’d want to fly on planes to exotic locations with, importantly, exotic problems.

The resolution of the Bitcoin experiment Turns out, building distributed solutions at scale is a people problem:

Bitcoin has no future whilst it’s controlled by fewer than 10 people. And there’s no solution in sight for this problem: nobody even has any suggestions. For a community that has always worried about the block chain being taken over by an oppressive government, it is a rich irony.
