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 This resolved warnings Apple started sending out to developers about using the out of date UIWebView.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....

Despite the more colloquial meaning that most are more familiar with, nonce is an important definition within computing, and particularly crypto Literally N-once, a nonce is an arbitrary number intended to be used just once during a communication - it's often used as a sort of salt to ensure that replay attacks cannot simply use old communications, as well as for IVs etc when encryption This short snippet will generate a nonce in both P..

I like these drawers from Land Shark Outfitters. With big names in the space pricing their systems at well over $1,000, I love the idea of a polished product at half the price. 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 . Having gone through that build process, though, and after seeing this system from Land Shark Outfitters, I think I could cu..

Sitting in my office looking at the people around me, it is hard to imagine working in a world where women aren’t an equal and integral part of the tech environment, yet, there’s still more that needs to be done to make this a normality. With only 14% of the tech workforce identifying as women; a number which has decreased over the last 20 years, what can we do? With Ada Lovelace Day approaching, I've been reflecting on her experience as t..
