In this post I explain a little about how to use Java’s Vector APIs, attempt to explain how they turn out fast, and then use them to implement a sorting algorithm 3x faster than Arrays.sort . I then explain some problems I found, and how I resolved them. Supporting code is published here .
I just did what no startup founder is ever supposed to do. I gave up. It wasn’t even one of those glorious “fail fast and fail forward” learning experiences. After seven months of hard work and two weeks before we were to start ...
He Sent $80 Million a Month to Secret Wallets Before Terra Luna Crashed
In the recent paper about "soulbound" tokens, Vitalik Buterin et al. write that they aim to build technology that is "acceptably non-dystopian". Do any of today's self-sovereign identity projects fit that bill?
Data races are among the most common and hardest to debug types of bugs in concurrent systems. A data race occurs when two goroutines access the same variable concurrently and at least one of the accesses is a write. See the The Go Memory Model for details.
A deep-dive
What if OpenSSL were a GUI program? Here's what it might look like.
Exciting news about how Arduino is forging new partnerships with Bosch, Renesas, Anzu Partners and Arm that will take things to new levels.
I am overjoyed to announce that the 2nd edition of my book Code: The Hidden Language of Computer Hardware and Software will be published by Pearson on August 19, 2022. As you can see, the covers of the two editions are nearly identical except that the 2nd edition uses the “dark mode” option:
A new CRISPR-based map ties every human gene to its function using a tool called Perturb-seq. The work was led by Jonathan Weissman and colleagues at MIT and the Whitehead Institute, and is free for other scientists to use.
Distributed work may hold the key to creating forward thinking metropolises.
Even with a lot of help from a good text editor, writing HTML can be a drag. Nice documents end up as tag-swamps with little bits of content perched atop hills of tabs. Editing them becomes a test of patience and we get sick at the thought of having to look at our once-loved text. It doesn't have to be like this!…

Why some systems -- as a consequence of their intrinsic dynamics -- require a control action that first pushes them the wrong way and makes things worse before it gets better.

The smell of fresh pine sawdust filled the air, with more floating up as I sanded the last rough corner of the stool. My toddler was happily sanding her own block off to the side.
This post is the fourth part of a three-part series 1 describing work that I have been doing to improve the Cranelift compiler. In this post, I'll describe the work that went into regalloc2 , a new register allocator I developed over the past year. The allocator started as an effort to port IonMonkey's register…
Last week a group of technologists, including Bruce Schneier, sent a letter to Congress outlining their concerns around cryptocurrency and urging Congress to regulate the space. Now let me be the f…
A team of engineers at the University of California San Diego has demonstrated for the first time that the Bluetooth signals emitted constantly by our mobile phones have a unique fingerprint that can be used to track individuals’ movements.
Vivaldi browser launches a powerful built-in mail client Vivaldi Mail with an integrated Vivaldi Calendar, and Feed Reader. Download desktop and notebooks.
Large neural networks are at the core of many recent advances in AI, but training them is a difficult engineering and research challenge which requires orchestrating a cluster of GPUs to perform a single synchronized calculation.
Available in public beta today, we're announcing Achievements as a new way to commemorate milestones on GitHub.
Some speculative hypotheses
Nuclear power currently makes up slightly less than 20% of the total electricity produced in the US, largely from plants built in the 70s and 80s.
