I have recently started experimenting with LoRa radios, and the LoRaWAN network protocol. Interestingly it seems that the LoRa ecosystem is simultaneously surprisingly open (both in specifications and implementations), while also having very little definitive documentation on how to actually get started as an indvidual hacker. As such I found the process of learning enough of the protocol to set up my own network surprisingly difficult. T..

Outside of QubesOS and ChromeOS, what's the best desktop OS when it comes to security? Can Linux compete with macOS's security model if properly hardened? (MAC on everything that's feasible to confine, bubblewrap sandboxes for every desktop app, sandboxed systemd services for daemons, "minimal" self compiled kernel with the GrapheneOS patches, hardened malloc etc). If not, are the BSDs possible to adequately secure without *too* much effor..
The nth-order effects of the recent CrowdStrike fiasco [1] [2] [3] will unfold over time. As it stands, it is apparently the single biggest global “tech outage” ever, which has already disrupted everything from airlines to railways to hospitals to financial systems amongst numerous others—globally.
Back in April, I introduced Fresh Eyes : a tiny macOS utility helping me take care of my eyes. I spend a bunch of time in front of a computer screen and Fresh Eyes has been helping me stick with the often recommended 20-20-20 rule . Fresh Eyes 1.7 ships a handful of improvements suggested by users: Postpone Fresh Eyes for 1 hour, 2 hours, 3 hours, or until the next day. Revamped notification. Revamped countdown screen. Reorgani....

GitHub offers permalinks to versions of files and lines, within a repository. They’re easy to create (y keyboard shortcut) and have some nifty affordances like displaying a preview, plus they don’t become invalid as code changes. Use them! The permalinks use the commit hash of a particular version of the file, and thus the contents never changes, because they’re content-addressed and permanent 0 . This is true even as the code evolves: ....
Edition 172 of my newsletter, discussing Knowledge Management, Knowledge Work, Zen Productivity, Personal Organization, and more!
I enjoy going to sporting events in person but I do not like sitting out in the sun the entire time. I attended the Orioles vs Yankees game with family and I was tasked with finding the seats for everyone. This was a responsibility I took seriously. I want to share how I went about finding seats that were in the shade the entire time the game was played. This also serves as documentation for myself when I will have to do this research....
Benthos, now renamed Redpanda Connect and the fork Bento, is a data stream processor, think anything Inputs: Kafka, NATS, SQS, S3, a socket, HTTP … modify the content, then send it to anything outputs. I love that tool so much, that I was convinced I’ve blogged about it already which I did not. It can be used for mostly anything streams related. Surely we could do the same thing with some real code as well, using our usual programming langu..
Introduction: Welcome to Episode 10 of our Ultimate Software Design series! In this episode, Bill dives into the integration of authentication and authorization mechanisms within Go packages, providing developers with essential strategies for securing and maintaining their software systems. Learn to configure and manage cryptographic keys using a KeyStore and integrate it into your Go applications. Discover how to create middleware..
Hi, Was wäre wenn…? Diesen Satz habe ich bestimmt hundertfach in den letzten Tagen zum CrowdStrike Ausfall gelesen. Überall werden Schuldige gesucht. Und das ist falsch! Wir erleben das klassische Blame-Game. Es ist wichtiger, einen Schuldigen zu suchen, als das Problem zu lösen. Damit schüren wir nur Angst. Einem Angestellten von Tom Watson, dem Gründer von IBM, war einmal ein Fehler unterlaufen, der die Firma zehn Millionen Dollar..

The rise of a new title in the data industry, Data Strategist, caught my attention recently. Initially, I was skeptical. "Isn’t this just a fancy term for a Data Manager?" I wondered. However, as I delved deeper, I realized my perspective was heavily influenced by my recent tenure at Doximity. At Doximity, the Data Engineering and Data Analytics Manager roles have always blended technical individual contributor work (often referred to as "I....
Bash-Oneliner is an excellent resource for Bash/Linux users. Most of the “tricks” are well-known, but there is always something to learn. More importantly, finding them all well organized in one file is rare. I use the reverse lookup of bash-history (Ctrl+R) daily. Still, only today (thanks to an HN comment on Bash-Onliner) did I learn that it also preserves one’s comments, which can be exploited to invoke complex commands quickly: ..

Neural networks are often thought of as opaque, black-box function approximators, but theoretical tools let us describe and visualize their behavior. In particular, let’s study piecewise-linearity, a property many neural networks share. This property has been studied before , but we’ll try to visualize it in more detail than has been previously done.
As our world becomes more and more digital, so does the need for us to periodically evaluate our technology habits. A 2023 reviews.org study found that people check their phone around 144 times a day. And according to Statista , people spend over 3 hours a day online at a PC for activities not related to work or school. Spending too much unstructured time on any device – whether it be a phone, tablet, or PC – has been linked to both ph..

Although COBOL can be considered a legacy language, there are still billions of lines of COBOL in production. Modernizing these systems which are costly to run and maintain is a challenge. One solution to this issue is a COBOL to Go transpiler that I want to present in this article.
In the future, computers will not crash due to bad software updates, even those updates that involve kernel code. In the future, these updates will push eBPF code. Friday July 19th provided an unprecedented example of the inherent dangers of kernel programming, and has been called the largest outage in the history of information technology. Windows computers around the world encountered blue-screens-of-death and boot loops, causing o....
