Modular Interpreters and Visitors in Rust with Extensible Variants and CGP

Programming Extensible Data Types in Rust with CGP - Part 2: Modular Interpreters and Extensible Visitors Posted on 2025-07-09 Authored by Soares Chen Discuss on Reddit, GitHub or Discord. This is the second part of the blog series on Programming Extensible Data Types in Rust with CGP. You can read the first part here. As a recap, we have covered the new release of CGP v0.4.2 which now supports the use of extensible records and variants, allowing developers to write code that operates on an

I've tested dozens of cheap portable power stations and this EcoFlow is my favorite

The EcoFlow River 2. Adrian Kingsley-Hughes/ZDNET Power banks have given way to power stations. And while I really like the colossal capacity offered by those behemoths, sometimes I want something I can grab quickly to take with me on a job or in an emergency. The EcoFlow River 2 fits the bill. EcoFlow River 2 specs Capacity : 256Wh : 256Wh Net Weight : Approximately 7.7lbs : Approximately 7.7lbs Dimensions : 9.6 x 8.5 x 5.7inches : 9.6 x 8.5 x 5.7inches AC Input : 100-120V 50Hz/60Hz, 36

Is Amazon Clearing Out the 2200W DJI Power Station? Now at a Record Low Price for Prime Day

Power stations are flying off the shelves on Amazon, especially from brands like Anker, EcoFlow, and DJI. This Prime Day, Amazon is offering deep discounts on most models, but the DJI Power 1000 with its 2200W output is one of the most attractive deals you’ll find. It’s now priced at an all-time low of $699 from $999, and it’s open to everyone—Prime members and non-members. If you ever wondered what in the world a power station is for, the answer is easy: it’s a portable energy answer that lets

How AI on Microcontrollers Works: Operators and Kernels

The buzz around “edge AI”, which means something slightly different to almost everyone you talk to, is well past reaching a fever pitch. Regardless of what edge AI means to you, the one commonality is typically that the hardware on which inference is being performed is constrained in one or more dimensions, whether it be compute, memory, or network bandwidth. Perhaps the most constrained of these platforms are microcontrollers. I have found that, while there is much discourse around “running AI

Restoring a ZX Spectrum+ Toastrack

Restoring a ZX Spectrum+ Toastrack I talk a lot about Commodore machines in this blog; they left a bigger dent in me growing up, but like most kids of my generation living in Portugal in the 80s, the first computers I played with were actually Sinclairs—first my friend’s ZX81 and then a ZX Spectrum 48K that my parents offered me. I have many memories of playing games like the Horace series, Manic Miner, Jetpac, or Chuckie Egg on my Spectrum. I’ve been keeping a few Timexes and Spectrums that h

The best cheap portable power stations of 2025: Expert tested and reviewed

I remember when power banks were new. They were an amazing development, freeing us from the tyranny of having to be near an AC outlet to charge out gadgets. Next came the power stations. They packed even more power into an admittedly bigger space. Still, we were freed from needing to be near to AC outlets or use extension cables when working outside, or in the RV or camping. The original power stations were big and expensive, so manufacturers to came up with smaller, more affordable models. Her

Can your terminal do emojis? How big?

Emojis are great. They're particularly useful to put in the output of scripts and get some eye catching output. At least provided they aren't overused, just like colour. $ important-command Lots of output... ‼️ Something went wrong! Some more output... But bigger emojis are better, right? The VT100, introduced in 1978 has a way to do bigger text. You can even play with this due to the wonderful PCjs VT100 implementation. The way it works is you use the DECDHL (DEC Double-Height Line) escapes

New paper pushes back on Apple’s LLM ‘reasoning collapse’ study

Apple’s recent AI research paper, “The Illusion of Thinking”, has been making waves for its blunt conclusion: even the most advanced Large Reasoning Models (LRMs) collapse on complex tasks. But not everyone agrees with that framing. Today, Alex Lawsen, a researcher at Open Philanthropy, published a detailed rebuttal arguing that many of Apple’s most headline-grabbing findings boil down to experimental design flaws, not fundamental reasoning limits. The paper also credits Anthropic’s Claude Opus

Rohde and Schwarz AMIQ Modulation Generator Teardown

Introduction Every few months, a local company auctions off all kinds of lab, production and test equipment. I shouldn’t be subscribed to their email list but I am, and that’s one way I end up with more stuff that I don’t really need. During a recent auction, I got my hands on a Rohde & Schwarz AMIQ, an I/Q modulation generator, for a grand total of $45. Add to that another 30% for the auction fee and taxes and you’re still paying much less than what others would pay for a round of golf? But i
