Web Development: What’s Big In 2019?

I try to keep up with web development trends but it’s hard to keep pace since it’s such a fast evolving field. Barely a week goes by without the release of a new JS framework, elaborate build tool or testing suite — all of them touted as the one to learn. Sorting the hype from the genuinely useful is no mean feat, so my aim in this article is to summarise some of the most interesting happenings that web development saw in the last year, and what trends we expect to see more of in 2019.

A technology or framework doesn’t have to be brand new to be on our list here, it just needs to be growing rapidly or evolving in an interesting way. Let’s take a look!

Framed Raspberry Pi Keeps Tabs On Spotify

Perhaps you’ve noticed, but we here at Hackaday have a slight obsession with the over-engineered. One could fairly say there’s a linear relationship between how likely we are to feature a project and how needlessly complex it is. That said, it isn’t as if we are unable to appreciate a minimalist approach. Taking the scenic route can be a lot of fun, but sometimes it’s nice to just get where you’re going before you run out of gas.

This very slick Spotify “Now Playing” display created by [Jon Ashcroft] is a perfect example of that principle. The hardware is so straightforward that it’s barely worth mentioning: a Raspberry Pi with a small HDMI display, tucked neatly into a photo frame. Nothing to get too excited about there. The real hook with this particular project is the software.

[Jon] is a web developer by trade, so it’s natural he would approach his personal projects with that same mentality. Rather than one of the “usual suspects” for a Pi project like Python, he wrote his software in ES6; which the Pi is running through Chromium in kiosk mode (full screen web content, no top bar). For those of you who aren’t keeping up on web languages, ES6 is short for EcmaScript 6: a new version of the standard on which JavaScript is based. It’s a bit heavier on resources than is strictly necessary, but it works well enough in the end.

Using Spotify’s excellent API, his software pulls down the current track information and stores it locally. It does this every ~4 seconds, checking to see if the track has changed. [Jon] isn’t thrilled with this brute force method, but it works for now. It displays the current playing song and artist, and uses a library called node-vibrant to extract a dominant color from the album art and use that to create a complementary background color. Very slick.

[Jon] provides all of his source code and made it easy to connect to your own Spotify account, so don’t be surprised if you see this running on a “Magic Mirror” near you soon.

FORTRAN For The Web

There’s an old saying: “I don’t know what programming language scientists and engineers will use in the 22nd century, but I know it will be called FORTRAN.” FORTRAN was among the first real programming languages and, along with LISP, one of the oldest still in common use. If you are one of those that still loves FORTRAN, you no longer have to be left out of the Web development craze thanks to Fortran.io.

Naturally, the Fortran.io site is served by — what else — FORTRAN. The system allows for Jade templates, SQLite databases, and other features aimed at serving up web pages. The code is hosted on GitHub, and you can find several examples there, as well.

If you’ve ever wanted to do formatted I/O to a web page, here’s your chance. Come to think of it, why not? We’ve seen servers in BASIC and even in Linux shell script. Of course, today’s FORTRAN isn’t the one we learned back in the 1970’s (we assume if you didn’t learn about FORTRAN in the 1970’s, you quit reading this post a while back… prove us wrong and show us your FORTRAN projects).

Hackaday Links: Christmas Eve, 2012

It’s Christmas Eve, the perfect time to interact with your extended familial units, eat cookies, nog things up a little, and watch Die Hard. Christmas Eve also means it’s a low-effort day here at Hackaday, so here’s a few cool things we’ve run across in the past few weeks.

A Round OLED Display

1_13inch_Round_OLED

That right there is a circular OLED display. [ArtistEngineer] over on reddit found this display on AliBaba. It’s a 1.13 inch diameter display with a resolution of 128×128 (yeah, we don’t know either). This looks like a great display for a DIY wrist watch, digital gauge, or loads of other devices where a square display doesn’t make much sense.

There seems to be a few circular OLED display manufacturers – including Truly Semiconductors who happened to put up a datasheet for their round display – but sourcing these in reasonable quantities is a pain. Anyone up for a group buy? Think of the fun you’ll have coding a polar coordinate display!

Computing with transistors

gate

So you know computers are made up of simple logic gates, latches, buffers, and other miscellaneous digital cruft,  but how do we turn these digital circuits into a computer? Over the last few months, [Andrew] has been putting up a bunch of blog posts on the application of digital logic. Start out on the ‘Computing with Transistors’ post before moving on to The Digital State and Circuits and Arithmetic. There’s some good readin’ there.

 Embedding 3D objects in a web page

Go ahead. Click it. It’s Sketchfab that allows anyone to publish interactive 3D designs without a browser plugin. If anyone out there is trying to build a Thingiverse clone that isn’t tied to Makerbot, consider using this for the preview page for each object.

Surprisingly, Twinkies were the one thing that didn’t survive the Apocalypse.

While there’s no use in mourning the death of the Twinkie – Little Debbie also makes small cream-filled cakes – you might as well include some Twinkies, Snowballs, Ding Dongs, and Ho-Hos in your Christmas baking. [scoochmaroo] on Instructables put together a list of homebrew recipes for the now defunct Hostess snack cakes.

Perfect for autonomous robots

code

[maxogden] over on the gits put together a script for automatically joining wireless networks on Linux. This was tested on a Raspberry Pi, and we’re thinking it would be perfect for whatever autonomous creation you’ll be building in your workshop next year.
