Asking a tech recruiter

2020-11-25

While working I mostly found the attention of recruiters slightly reassuring but often annoying. I think that annoyance is fairly common, usually built up from countless LinkedIn drive-by attempts from unreading keyword-hunting recruiters. I thought that now, out on my own, maybe this legion of recruiters can be my sales department....

The Mac is losing me

2020-11-18

I've been mostly happy using a Mac since I got myself my first computer earned with programmer money. I believe it was a mid 2009 15" MacBook Pro. That was a computer I used at least until 2016 which I consider very decent usable life. At that point I had replaced the hard-drive with an SSD, upgraded the RAM and switched a battery that was worn out. I stopped using it when it just straight died some time in 2016....

The BEAM marches forward

2020-10-26

The BEAM is the virtual machine that Erlang and Elixir runs on. It is widely cited as a battle-tested piece of software though I don't know in which wars it has seen action. It has definitely paid its dues in the telecom space as well as globally scaled projects such as Whatsapp and Discord. It is well suited to tackle soft-realtime distributed systems with heavy concurrency. It has been a good platform chugging along. And with a small team at Ericsson responsible for much of its continuing development it has been managed in a deeply pragmatic way. Erlang has always been a bit of a secret and silent success. Almost no-one uses it if you look at market shares. But among the ones that use it there seems to be a very positive consensus. And then Elixir came and caused a bit of a boom. I think the BEAM has benefited from Elixir and Elixir wouldn't exist without the BEAM. With that bit of background I'd like to shine a light on some cool developments that I think makes the BEAM more interesting or even uniquely interesting in the future....

Stupid solutions: Live server push without JS

2020-09-25

So in my post Is this evil? I covered a way of tracking users with CSS. While thinking about those weird ways of using the web I also started thinking about pushing live data to clients without JS. Or at least maintaining a connection. So WebSockets requires JS. WebRTC requires JS. Even HLS (video streaming), which would otherwise be super cool, with captions for accessibility. But no. Or rather, maybe on Apple platforms. Eh. Not good enough....

Is this evil?

2020-09-15

I try to be a friendly citizen of the web. I try to keep my site in good shape. It should load quickly, track nothing beyond your basic server logs, not hassle you about cookies, GDPR or my newsletter. I do have a newsletter but it won't pop up in your face here. I try to stay firmly on the side of friendly and a good experience in how I run this site....

Nerves-keyboard - Running a mechanical keyboard with Elixir

2020-09-01

Chris Dosé was interviewed by us on Elixir Mix. When he spoke about his work on a Nerves-powered keyboard I knew this was a project I wanted to try out. So I dropped into their dev channel, acquired the hardware (thanks for the help) and have done some playing around with it....

Simple Solutions: UI choices without JS

Beam Bloggers Webring

2020-08-19

This is a brief announcement. If you are interested in following bloggers in the BEAM, Elixir, Erlang, etc. ecosystem or you blog yourself. Please check out beambloggers.com to get in on the old-school webring action. Bloggers can join it. It might lead to some traffic. Mostly it is a small nod to a stranger old time on the web when sites organized in rings for discoverability. I think the need for discoverability remains and some webrings have been showing up again. You can find the shuffler for the webring at the bottom of my site as well and just let it carry you to a new site....

The Strong Technologies

2020-08-14

I feel like a curmudgeonly sort recently. I'm honestly a pretty optimistic and positive person. But I'm becoming increasingly technically curmudgeonly. I don't think it is age turning me conservative. But I feel like I'm moving back to what I find tried and true in many ways. I feel resentful in a lot of cases where I can't really reasonably go back. So what am I talking about here?...

The best parts of Visual Studio Code are proprietary

2020-08-03

I've been very surprised and delighted over a number of years now by Microsoft's strong efforts in open source. I understand the skeptics, I was on Slashdot when they tried to sue Linux out of existence and I think only time will tell. I figure MS contributing is better than them hunting Linux distributions for sport. So I was mostly onboard for Microsofts efforts and I've especially found Visual Studio Code useful....

Five Buck Fatigue

2020-07-23

This is about a reaction I noticed with myself in response to membership programs, patreons and individual sponsorship as I've run into significantly more of these following Corona. The advertising-supported model has confirmed many of the concerns about its sustainability and creators are looking for more reliable options. I think this feeling I have might be something other people experience and something for creators to be prepared for....

"More than one thing at a time"

2020-06-17

On a recent Elixir Outlaws episode Chris Keathley told us all a nice story of the advantages of Elixir as opposed to Ruby. His frustration with Ruby and appreciation of how Elixir works resonate at the frequency of my own frustrations and joys. I believe my titular quote is accurate, that's one of the primary things he noted. How nice it is to use a runtime that can do more than one thing at a time....

A wall too tall - Nerves & k3s

If you want more in-the-moment writing, the newsletter is more temporally anchored publication (signup further down, no pop-up)....

Check yourself - Web developer self-evaluation

2020-04-08

I've been thinking a lot about inexperienced (junior, if you must) web developers and just how much there is to learn about programming in general but the web in particular. You often hear people say that you don't need to know everything but you should have a solid foundation. Well, how do you establish a solid foundation and how do you know if you have one? How do you get introduced to all the relevant terminology and how do you find out what you haven't learned yet?...

I always want to do it all

2020-03-09

My brain has very little chill on a day-to-day basis. There are moments where I can find a very peaceful state of mind. Doing something menial in the garden for an extended time, cooling off outside after a while in a sauna, winding down after heavy exercise. At most other times my mind is usually working on something or I'm itching with the need to do things....

Ecto & Multi-tenancy - Dynamic Repos - Part 2

In the first part I covered the basics of getting started with Dynamic repositories with Ecto.

Building blocks for something better. I'll try to get into the better bits here....

But this post is about a corner full of nuts, bolts andvery little of the shiny or hot stuff. It just covers some rather specific needs. Ecto docs for these features arethis guide and this API. But that is usually not thewhole picture. I'll try to cover some of the practicalities....

An eInk display with Nerves & Elixir - Getting started with Inky

2019-07-07

So I've been curious about what kinds of displays you can connect to the Pi-series single board computers for a while. I happened to accidentally order a few. Among others an eInk display. I ordered the PaPiRus ePaper. It ended up being dead on arrival and then out of stock so I received an Inky to replace it. Fair enough....

Why am I interested in Elixir?

2019-06-11

I’ve had Elixir on the brain recently. And by recently I probably mean 2 years. In my defense I think it is fair to say it is blooming right now. I haven’t had much need of it, or opportunity for it, in my day-to-day of maintaining a Python legacy system, renewing another legacy or optimizing Elasticsearch. So I’ve tried it with a few hobby projects I’ve spent time on and that was fun. But mostly I really just watched the community and what they did with a feeling of “Shiiiit, I want in on some of that!”. I'll primarily touch on BEAM, OTP, Phoenix Presence, Phoenix LiveView, Nerves, Scenic and Rustler....
