But having 5,316,911,983,139,663,491,615,228,241,121,378,304 2 possible values made it way harder than it needed to be to write them all down. I’m not sure why the authors of the UUID spec wanted to include so many bits!
In 1980 IBM, under pressure from its customers to provide computers for personal use, not just mainframes, set out to create the IBM PC; given the project’s low internal priority but high external demand they decided to outsource two critical components: Microsoft would provide the DOS operating system, which would run on the Intel 8088 processor.
A reference design is exactly that: a design that can be used as a reference for building your own. Not mandatory design, nor for that matter a suggested design. The amateur radio station components listed here will provide you with a working station. I am purchasing these too, so that my tutorial and demonstration videos will use the reference station.
I’ve been asked many times, “What HF rig should I buy.” I used to answer, “Well, it depends.” No more. Now I say, “Buy what’s in the reference station: an Icom IC-7300.” I will try in every case to make a recommendation for something you can purchase, and minimize the number of things you must build.
Your circumstances will be different from mine. Perhaps you already have a radio in your station, and don’t want to change. No problem! Adapt the reference station to your needs. Note that my own station has capabilities, like a hex beam, that won’t be in the reference design. But the reference design can be a useful guide as you build out your station from the ground up, or if you’re upgrading it.
Welcome! Here you'll find a sampling of tools for connecting online including delightful musical collaboration sites, collaborative drawing sites, online galleries, weird experiments, corporate video-meeting tools, and office tools repurposed as spaces for gathering together.
What these tools have in common
Invite people to reach each other over the internet through typing, voice, video, drawing, music, or any expression that feels meaningful Priority to tools accessed for free through a browser Priority to the experimental, weird, home-made, simple, or barely working (anything with any interesting features is welcome)
The standard trope when talking about timezones is to rattle off falsehoods programmers believe about them. These lists are only somewhat enlightening – it’s really hard to figure out what truth is just from the contours of falsehood.
So here’s an alternative approach. I’m gonna show you some weird timezones. In fact, the weirdest timezones. They’re each about as weird as timezones are allowed to get in some way.
Asia/Kathmandu has a weird offset from UTC Africa/Casablanca doesn’t fit into the timezone model cleanly, so it’s hard-coded America/Nuuk does daylight savings at -01:00 (yes, with a negative) and Africa/Cairo and America/Santiago do it at 24 o’clock (not 0 o’clock) Australia/Lord_Howe, population 382 and some notable stick bugs, has the weirdest daylight savings rule To learn how their weirdness is represented in software, we’ll look at the raw timezone files that all software ultimately relies on. From there, two things will become clear:
Yeah, this stuff is weird But only finitely so, because ultimately a computer’s gotta implement them But first, an aside on the calendar.
Hi, I’m Cabel. I was driving to Seattle and got hungry, so I stopped at a McDonalds in Centralia, WA. And when I went inside, I saw something incredible.
Always great to get another Julia Evans * wizard zines * comic. This one is on the Linux Path command.
Pitt and Clooney—they are used to living like this. Surrounded by beauty. In majestic isolation. They have been friends for nearly a quarter-century, in part because of what they share: an understanding of where the road that every young actor dreams of walking—that road that represents some intoxicating combination of money and attention and success—ends up. It ends up here. In a place a regular human could barely describe (trust me, I’m trying), let alone relate to. What else can you do but laugh?
The lab technician role was among the lowest rungs on the Social Science ladder. My boss was a tenured professor who was somehow protecting grant money by hiring a minimum-wage lab technician. Her description of the role during the interview versus what she described on my first day had little intersection.
Modern JavaScript regular expressions have come a long way compared to what you might be familiar with. Regexes can be an amazing tool for searching and replacing text, but they have a longstanding reputation (perhaps outdated, as I’ll show) for being difficult to write and understand.
Welcome to IEEE Spectrum’s 11th annual rankings of the most popular programming languages. As always, we combine multiple metrics from different sources to create three meta rankings. The “Spectrum” ranking is weighted towards the profile of the typical IEEE member, the “Trending” ranking seeks to spot languages that are in the zeitgeist, and the “Jobs” ranking measures what employers are looking for.
In our goal of trying to estimate a programming language’s popularity, we realized that no one can look over the shoulder of every person writing code, whether that be a child writing a Java script for a personal Minecraft server, a mobile app developer hoping to hit it big, or an aerospace engineer writing mission-critical code for a voyage to Mars. Our Top Programming Languages interactive tries to tackle the problem of estimating a language’s popularity by looking for proxy signals.
ContextMenu
Many years ago I found ContextMenu ($4.99) which solves all of the issues I have with the Automator approach. There’s also a free version, ContextMenu Lite, that supports up to 3 actions to give you a taste of the good stuff.
Submenu is optional Apply to multiple types (files or directories; can be as granular as file extension) Show output (sometimes you want to see the results of the command) Confirmation before running (if it’s a potentially dangerous operation)
The year was 1978 and I was mowing lawns and doing odd jobs around my neighborhood to earn enough money to buy the coolest thing I had ever seen, a TRS-80 Model 1 computer at my local Radio Shack. It was awesome and changed the direction of the rest of my life. I spent all my free trime working with it and doing even more odd jobs to buy all the expansion options. I totally speced it out with a monitor, casset tape drive and eventually the expansion kit with a parallel printer. It started a life long hobby and a carreer that took me all over the county. Such great memories!
trs80gp primarily emulates the "gray" line of TRS-80 computers made by Tandy in the late 1970s and early 1980s. They are known as the Model I, Model II, Model III, Model 4, Model 4P, Model 4D, Model 12, Model 16 and Model 6000. It is generally easier to use ordinary digits for the Model 1, Model 2 and Model 3. The Model 1, 3 and 4 are a line of compatible computers as is the Model 2, 12, 16 and 6000.
An SSH honeypot is a fake SSH server that you can run on your Raspberry Pi to capture bad actors. A user or bot attempting to access your network would get stuck in the honeypot.
With all the different types of filament available, it can be hard to keep track and know which one is best suited for your project. Bambu Lab thinks so and has released a new interactive guide to help you choose.
Mac cloud services provider MacStadium today unveiled Orka Desktop, a free virtualization tool that allows Mac users to create and manage macOS virtual machines locally via an easy-to-use admin panel.
Picamera2 WebUI is a lightweight web interface for the Raspberry Pi camera module, built on the Picamera2 Python library and using Flask. This project provides a user interface to configure camera settings, capture photos, and manage images in a basic gallery.
How can we understand the operations of technology and power in our era? Our technological systems are increasingly complex, interconnected, automated and opaque. Social institutions, from schools to prisons, are becoming data industries, incorporating pervasive forms of capture and analysis. Even places that were once off-limits to capital, from our emotional expressions to outer space, are now subject to computational control and extraction. Meanwhile, the industrial transformations in AI are
A microcontroller Macintosh
This all started from a conversation about the RP2040 MCU, and building a simple desktop/GUI for it. I’d made a comment along the lines of “or, just run some old OS”, and it got me thinking about the original Macintosh.
Career Advice from Jim Donovan I stumbled upon “The Making of an Investment Banker”, a talk given by Jim Donovan to the UVA school of law, which was posted to their YouTube channel. I found the advice to be quite good, regardless of your chosen career path, investment banker or otherwise. 3 pieces of advice before starting your career / job: Read the Wall Street Journal every day, no matter what. You should read 3 articles: one macro article, such as related to what the Fed is doing with interest rates, for example. one on a specific company that recently released earnings, or a specific transaction / acquisition. one op-ed
A consortium of U.S. federal agencies has pooled their funds and wide array of expertise to reinvent the emergency vehicle. The hybrid electric box truck they’ve come up with is carbon neutral. And in the aftermath of a natural disaster like a tornado or wildfire, the vehicle, called H2Rescue, can supply electric power and potable water to survivors while acting as a temperature-controlled command center for rescue personnel.
If you were around when the Model T was first announced, you could have built the organizations that became Disney, McDonald’s and Holiday Inn, all of which were powered by cheap, plentiful cars. You could have become a major developer of suburbs, mortgage banking and even pop music record labels (car radios changed the way music was consumed).
AI is here now, and the pace is astonishing. So far, I haven’t seen many freelancers or small businesspeople choosing to make an impact by understanding what it can do and selling processes and services to bigger organizations in ways that dramatically change how they do business.
