Over the past few years, I’ve taken to using technology less and less in my daily life. I leave my phone in the car when going to a party or social event. I’ll only fetch it if I want to take a picture, and only after appreciating the moment I’d like to capture to the fullest. When I listen to music on my phone (via headphones) during the long walks I take to get exercise and relax, I don’t check my phone at all. If the environment around..

Needed to rewrite the date format in a couple of csv columns. Emacs multiple cursors helps here, but needed a function to parse and reformat the dates themselves. I can likely reformat dates using the built-in parse-time-string and format-time-string functions, but hey why not give the ts.el library a try… (defun ar/region-to-timestamp () "Convert date like \"29 Apr 2019\" to \"2019-04-29\"." (interactive) (let ((date (ts-parse ..

Released a tiny npm package today: @0xadada/random-emoji , a javascript random emoji function with zero dependencies. $ yarn add @0xadada/random-emoji $ node > const random = require('@0xadada/random-emoji'); > random() '😁' let a = random(); // defaults to 'emoticons' let b = random('emoticons'); let c = random('food'); let d = random('animals'); let e = random('expressions'); console.log(a, b, c, d, e); // 😍 🙄 🍗 🐥 🤢 Small, fun.

When writing long sentences in documentation repositories, git tends to show really unhelpful diffs. They are unreadable because long lines aren’t broken, which hides edits happening towards end of line. A colleague of mine asked me if git couldn’t be configured to make this sort of thing more obvious. Challenge accepted! Figure 1: Can you spot the edit made in a long line of text?

Emacs dired is a powerful directory browser/editor. By default, it shows lots of handy file and directory details. I typically prefer hiding file and directory details until I need them. The built-in dired-hide-details-mode makes this easy with the "(" key toggle. Coupled with Steve Purcell 's diredfl (for coloring), it strikes a great user experience. With a short snippet, you can also show/hide dired details in style: (u..

Maps are fun, self hosted maps are awesome ! Serving world maps was reserved to big companies like Google, thanks to the OpenStreetMap project, we now have access to an open world of data. Generating Tiles MapBox (and others) worked hard to create a vector format bundled in a SQLite file: mbtiles format. It’s vector based as opposed to older raster maps containing 256x256 PNG images. The Openmaptiles folks did a great job automating the map..

Here’s a blog entry about some “new” Oracle execution plan displaying scripts that I’ve had since 2011 or so - I just tidied them up recently and added some improvements too. My aim in this blog post is not to go deep into SQL tuning topics, but just show what these scripts can do. The new scripts xb.sql and xbi.sql ( eXplain Better and eXplain Better, by sqlId ) are in my GitHub repo. Make sure you pull the latest changes as I uplo..

We at Canonical have been hard at work on the security features of version 2 of the Robot Operating System (ROS 2). However, if we lift our collective heads up out of the weeds it’s easy to see folks completely misunderstanding how security works today in ROS 2. We’ve written some design articles to help distill all the moving pieces into something comprehensible, but I wanted to do the same here in a slightly less formal way.

We still have features to cover from our summer vacation but we need to make a short de-tour through newer things that landed recently. One of the big highlights is the switch to WKWebView . We effectively changed the default iOS browser component to WKWebView instead of UIWebView. This resolved warnings Apple started sending out to developers about using the out of date UIWebView. This mostly went unnoticed by most developers as it shou..

I see U-Haul’s video on the importance of proper trailer loading resurface every once in a while, and most recently at Jalopnik . I do my best to avoid trailers . I don’t even like pulling them on paved roads, and off-road, they make all but the easiest tracks impossible. If you get stuck using one, though, at least know how to load it. Permalink.

We are excited to share that we now support customized license instructions, helping the teams in your organization collaborate better together on licensing compliance: legal teams can better equip developers to shift compliance left by customizing license policies with clear instructions, and developers can then more easily integrate license analysis as part of their routine workflow.

Every year, on the second code Tuesday of October, we celebrate Ada Lovelace Day - an important opportunity to appreciate the achievements of women in science, technology, engineering and maths (STEM). As an unapologetic feminist, I’ve never needed much of an excuse to celebrate amazing women who’ve been paving the way and shaping the world in which we live. However, over the years, I’ve become disheartened by the predictability of such occ..

HLS Stream Creator is a script which acts as a wrapper to FFMPEG in order to simplify remuxing video into HTTP Live Streaming (HLS) format. Originally written as research into HLS for a job interview, I've continued to develop it and since used it for a range of projects, including creating a raspberry-pi based transcoding cluster .

Do you think there are any declarative programming languages at the moment that are developed enough to be useful? Declarative programming is a really fascinating subject, I just wish there was more research/development there. Prolog has been the number one in the field forever, but things like Sentient Lang and Mercury are able to do similar things while being a much newer and more featureful language. That being said, with a proper de..

So I recently learned about cargo doc --open while attending the Colorado Gold Rust conference. However, on my linux mint machine it opened the docs in chrome instead of my default web browser which is firefox. Since I spent most of my morning rust coding time tracking down why that was and how to fix it, I figured I write a blog post about it. So here goes: By looking at the cargo source, I was able to see that a separate crate named o....

Lets say you encounter a bug in the software you work on. Maybe a user informs you of the bug, or you find it yourself. Let's say this bug has been in your software for a little while, and is not a bug you just added in the last hour or so. This implies that your unit tests did not catch the bug. Here's the process I recommend for fixing the bug: 1) Work out what the problem is. 2) Work out the solution, edit your source files unti....

My sleeping platform came out to about $600, with two sets of $215 36“ lock open/close slides and a $145 pair of 28” base mount slides .
