How it feels to learn JavaScript in 2016 – Hacker Noon (hackernoon.com)

No JavaScript frameworks were created during the writing of this article.

The following is inspired by the article “It’s the future” from Circle CI. You can read the original here. This piece is just an opinion, and like any JavaScript framework, it shouldn’t be taken too seriously.

Hey, I got this new web project, but to be honest I haven’t coded much web in a few years and I’ve heard the landscape changed a bit. You are the most up-to date web dev around here right?

-The actual term is Front End engineer, but yeah, I’m the right guy. I do web in 2016. Visualisations, music players, flying drones that play football, you name it. I just came back from JsConf and ReactConf, so I know the latest technologies to create web apps.

Cool. I need to create a page that displays the latest activity from the users, so I just need to get the data from the REST endpoint and display it in some sort of filterable table, and update it if anything changes in the server. I was thinking maybe using jQuery to fetch and display the data?

-Oh my god no, no one uses jQuery anymore. You should try learning React, it’s 2016.

Oh, OK. What’s React?

A year or two old, and I’d love to claim that things were better in Javascript-framework-land today… but they’re not.

git git git git git

Ever found you’ve accidentally entered too many gits in your terminal and wondered if there’s a solution to it? I quite often type git then go away and come back, then type a full git status after it. This leads to a lovely (annoying) error out the box:

$ git git status
git: 'git' is not a git command. See 'git --help'.

What a git.

My initial thought was overriding the git binary in my $PATH and having it strip any leading arguments that match git, so we end up running just the git status at the end of the arguments. An easier way is to just use git-config‘s alias.* functionality to expand the first argument being git to a shell command.

git config --global alias.git '!exec git'

Which adds the following git config to your .gitconfig file

[alias]
  git = !exec git

And then you’ll find you can git git to your heart’s content

$ git sha
cc9c642663c0b63fba3964297c13ce9b61209313

$ git git sha
cc9c642663c0b63fba3964297c13ce9b61209313

$ git git git git git git git git git git git git git git git git git git git git git git git git git git sha
cc9c642663c0b63fba3964297c13ce9b61209313

(git sha is an alias for git rev-parse HEAD.)

See what other git alias’ I have in my ~/.gitconfig, and laugh at all the typo corrections I have in there. (Yes, git provides autocorrection if you enable it, but I’m used to these typos working!)

Now git back to doing useful things!

Why I Still Use Vim

This is a repost promoting content originally published elsewhere. See more things Dan's reposted.

I often get asked about why I use Vim as my primary editor, there is no particular reason for this, except that I ended up learning it when I moved over to Linux full time many years ago. I ended up liking it because I could edit my small source files on my quad-core machine without needing to wait forever for the file to open.

Keyboard with Vim keycaps

Sure Vim isn’t a bad editor, it’s highly extensible, it’s easy to shell out to the, err well shell, its everywhere so when you ssh into some obscure server you can just type vim (or vi) and you’re good to go…

Engineering Empathy

This is a repost promoting content originally published elsewhere. See more things Dan's reposted.

This was a talk I gave at an internal R&D conference my last week at Workiva. I got a lot of positive feedback on the talk, so I figured I would share it with a wider audience. Be warned: it’s long. Feel free to read each section separately, though they largely tie together.

Why do you work where you work? For many in tech, the answer is probably culture. When you tell a friend about your job, the culture is probably the first thing you describe. It’s culture that can be a company’s biggest asset—and its biggest downfall. But what is it?

Culture isn’t a list of values or a mission statement. It’s not a casual dress code or a beer fridge. Culture is what you reward and what you don’t. More importantly, it’s what you reward and what you punish. That’s an important distinction to make because when you don’t punish behavior that’s inconsistent with your culture, you send a message: you don’t care about it…

Why it is just lazy to bad-mouth Ruby on Rails

This is a repost promoting content originally published elsewhere. See more things Dan's reposted.

It’s inevitable these days: we will see an article proclaiming the demise of Ruby on Rails every once in a while. It’s the easiest click bait, like this one from TNW.Now, you may say “another Ruby fanboy.” That’s fair, but a terrible argument, as it’s a poor and common argumentum ad hominem. And on the subject of fallacies, the click-bait article above is wrong exactly because it falls for a blatantly Post hoc ergo propter hoc fallacy plus some more confirmation bias which we are all guilty of falling for all the time.

I’m not saying that the author wrote fallacies on purpose. Unfortunately, it’s just too easy to fall for fallacies. Especially when everybody has an intrinsic desire to confirm one’s biases. Even trying to be careful, I end up doing that as well…

You Are Not Google – Bradfield

This is a repost promoting content originally published elsewhere. See more things Dan's reposted.

Software engineers go crazy for the most ridiculous things. We like to think that we’re hyper-rational, but when we have to choose a technology, we end up in a kind of frenzy — bouncing from one person’s Hacker News comment to another’s blog post until, in a stupor, we float helplessly toward the brightest light and lay prone in front of it, oblivious to what we were looking for in the first place.

This is not how rational people make decisions, but it is how software engineers decide to use MapReduce…

What Happens When You Mix Java with a 1960 IBM Mainframe

IBM Mainframe

As an engineer for the U.S. Digital ServiceMarianne Bellotti has encountered vintage mainframes that are still being used in production — sometimes even powering web apps. Last month she entertained a San Francisco audience with tales about some of them, in a talk called “7074 says Hello World,” at Joyent’s “Systems We Love” conference.

Created under the Obama administration, The U.S. Digital Service was designed as a start-up-styled consultancy to help government agencies modernize their IT operations, drawing engineering talent from Google, Facebook and other web-scale companies.

Or, as President Obama put it last March, it’s “a SWAT team — a world-class technology office.”

So it was fascinating to hear Bellotti tell stories about some of the older gear still running, and the sometimes unusual ways it was paired with more contemporary technology…

Rails is f*cking boring! I love it.

Together with a friend I recently built Dropshare Cloud. We offer online storage for the file and screenshot sharing app Dropshare for macOS/iOS. After trying out Django for getting started (we both had some experience using Django) I decided to rewrite the codebase in Rails. My past experience developing in Rails made the process quick — and boring…

A Constructive Look At TempleOS

This is a repost promoting content originally published elsewhere. See more things Dan's reposted.

TempleOS is somewhat of a legend in the operating system community. Its sole author, Terry A. Davis, has spent the past 12 years attempting to create a new operating from scratch. Terry explains that God has instructed him to construct a temple, a 640×480 covenant of perfection. Unfortunately Terry also suffers from schizophrenia, and has a tendency to appear on various programming forums with a burst of strange, paranoid, and often racist comments. He is frequently banned from most forums

How a bullet turns into a beep

Here’s a minor mystery:

echo •

That last character is U+2022. Select that line with the mouse, right-click, and select Copy to copy it to the clipboard. Now go to a command prompt and paste it and hit Enter.

You’d expect a • to be printed, but instead you get a beep. What happened?
