Email shouldn't feel like a dark art, but to a lot of people it does. Everyone should have DMARC setup by this point, but they don't. Here's the first piece of a 3 part guide covering why it works and how to set it up.Since writing about how to reverse account takeovers last week I've decided to write a security series covering all the weird things I encountered back in 2012, when I accidentally ended up combating phishing and fraud for a y..

Over the last couple of months, I’ve been posting a series of videos about early PC gaming and programming on my YouTube Channel . It’s been quite a fun journey and I thought I might write a few words about it. I have a lot of nostalgia for early games, which makes sense since it was how I spent most of my free time in the 80’s and 90’s. Times were boring before the Internet :)

I’ve been messing with Git a little more recently, and a question about rebasing popped into my head:

Pizza courtesy of Pizza for Ukraine! Donate Now to Pizza for Ukraine As I've written, I'm acutely interested in using software written in Rust as my daily drivers. What I've seen so far is that programs written in Rust, based on an admittedly tiny sample, seem to be higher quality than programs not written in Rust. In this blog post, I'm going to talk about what I had to do to make NuShell be usable for myself under OSX Monterey. ....

I've thought for a while now that the Github contributions heatmap is a particularly uninteresting page. This thought popped into my head once more after reading a fantastic ebook on the fundamentals of Git , so armed with new confidence and knowledge of Git commits, I decided to fake

The visitor pattern is an esoteric programming pattern that has never been widely popular. No one seems to be totally certain on what it’s good for, as demonstrated by the diversity of opinions found on StackOverflow . One notable quote from the software engineering StackExchange sums up the vibe: Visitor pattern has the most narrow use and almost never will the added complexity be justified My brother’s as..

We consider the following dynamical system: $$ \begin{cases} \dot{x}_1 = L(a_1, k_1, x_3) - k_1 x_1,\\ \dot{x}_2 = L(a_2, k_2, x_1) - k_2 x_2,\\ \dot{x}_3 = L(a_3, k_3, x_2) - k_3 x_3, \end{cases} $$ where $L$ is a piecewise linear function: $$ L(a, k, x) = \begin{cases} ak & \quad \textrm{for}\; 0 \leq x \leq 1,\\ 0 & \quad \textrm{for}\; 1 < x. \end{cases} $$ In this case study, we build a Shiny application that draws 3D phase port..

Some time ago I wrote about building an Australian search engine by abusing how AWS Lambdas work. You can view it at bonzamate.com.au , and read the post about it here . Recently I noticed that Bonzamate.com.au was in turn being abused by a series of bots repeatedly making queries against it. Now normally I don’t worry about bots. There is little you can do to stamp them out entirely, and its always nice to see someone trying to explo..

I’m not on many social media platforms these days. I like it like that. I mostly follow some academics and people who post interesting stuff. I post only occasionally, usually to show off my recent hiking exploits. I’ve come up with some rules for myself (all subject to change) about what I post. A post must meet all the following criteria: It must be positive and uplifting. There’s enough that’s negative on the internet. Don’t add ....

When you use GitLab to host your web software development project source code, you can deploy your website to Cloudflare Pages. Normally, you would use the GitLab CI pipeline to build your website project. So in this article, I show you how to configure your GitLab CI to deploy to Cloudflare Pages.

COVID necessitated WFH when I was still at EA. EA quickly took measures and closed the office. They issued an allowance for people to buy equipment to work from home. I opted to work from a work-issued laptop and ordered a Varier Variable Balans kneeling chair with my allowance.

Our last post was a pretty gloomy one overall (or t'least, twas for us, n we're still looking for flatmates), but I promise this one's just good vibes ^^ So, we were at Christopher Street Day in Rostock today, n twas a lotta fun. (As for what that's, several cities here in Germany call their pride parades "Christopher Street Day", or shortly "CSD", in remembrancea the Stonewall riots happening in Christopher Street back in 1969, note it's n....

As a 13 year old, my dad’s advice on internet presence was: “Everything you post will be used against you in the future. So you should never associate your name with anything on the internet”. As a rebellious teenager my view was the opposite: “Everything you post on the internet will get lost. You should associate your real name with everything you find interesting” I think looking back, this might be the most useful lesson I..

The Elements of Style urges us to "omit needless words": Vigorous writing is concise. A sentence should contain no unnecessary words, a paragraph no unnecessary sentences, for the same reason that a drawing should have no unnecessary lines and a machine no unnecessary parts. This requires not that the writer make all their sentences short, or that they avoid all detail and treat their subjects only in outline, but that they make every ....

The Learning With Errors problem is the basis of a few cryptosystems, and a foundation for many fully homomorphic encryption (FHE) schemes. In this article I’ll describe a technique used in some of these schemes called modulus switching. In brief, an LWE sample is a vector of values in $\mathbb{Z}/q\mathbb{Z}$ for some $q$, and in LWE cryptosystems an LWE sample can be modified so that it hides a secret message $m$.

Did you ever experience programming burnout? What I mean is inability to write any code. I quit my last job, which I liked very much, because I found myself unable to perform the simplest task. I wrote one driver for microcontroller, then I spent about month on writing much simpler and easier driver, because I procrastinated and didn't actually focus and write anything. This problem only becomes worse over time. In the past I was able to fi..

So, there was a post by Justine Tunney about her port of OpenBSD’s pledge() to her own libc, the Cosmopolitan libc . She is also calling out that previous attempts at this were flawed: There’s been a few devs in the past who’ve tried this. I’m not going to name names, because most of these projects were never completed. […] The projects that got further along also had oversights like allowing the changing of setuid/setgid/sticky ....

We arrived at 2:40pm on a Saturday, and there were only a dozen cars in the parking lot, with spaces for a few dozen more. There are no facilities at the trailhead, but the Coldwater Ridge Visitor Center and Johnston Ridge Observatory are both just a short drive away. We hiked clockwise around the Hummocks Trail loop. (As an aside, confusingly there is another WTA hike named Hummocks Loop, but as far as I can tell, it’s actually the same ..

The fee is $8 per adult, but federal interagency recreation passes get you free entry (e.g. America the Beautiful Pass). Unlike at other trailheads, do not leave the pass in your car. Take it with you into the Johnston Ridge Observatory and claim your free entry (a wristband). We arrived at the Johnston Ridge Observatory around 11am on a Saturday. The parking lot was about half full, but it is massive, so finding a space was not an issue.

I'm a fan of the unzip command line utility that ships with macOS. I give it a .zip file and it unzips it for me. No flags or arguments to remember (for my typical usages anyway). Most importantly, I've fully internalized the unzip command into muscle memory, probably because of its perfect mnemonic . But then there's .tar, .tar.gz, .tar.xz, .rar, and a whole world of compression archives, often requiring different tools, flags, etc. a....

We write a lot of code at Doximity, and every line that we ship to production gets reviewed. We spend a lot of time on code reviews, therefore it's wise to reflect on our process. Everyone has their review process, but it all boils down to the three buckets that GitHub provides: Approve Comment Request Changes But when should we choose "Request Changes"? That's often a tough line to draw. Sometimes, it even results in difficult ....

How maintainable is your Python code? Is it possible to hold the code for your functions in your head? When is it appropriate to use measurements in a code review? This week on the show, Reka Horvath and Ben Martineau from Sourcery are here to discuss their recent PyCon talk, "Actionable insights vs ranking: How to use and how NOT to use code quality metrics."

Welp, it looks like I'm starting a new company after all. Here are the values that I drafted for it. Values These things we believe: Ethics . We will behave ethically in all situations. Writing Things Down . We will work from home and be a distributed culture. And in a distributed culture, things have to be written down. Good writing is a skill for everyone not something reserved for writing. Having the Hard Conversations Resp....
