Our processors typically do computations using small data stores called registers. On 64-bit processors, 64-bit registers are frequently…
By now it is difficult to imagine that once there was a time when the utility, and even the possibility, of recursion in programming was in doubt. Yet that was true of the programming community aro…
A blog for third-party developers on the Clover POS platform.
On October 26, a YouTube user named crimewriter95 posted a full-length version of Pulp Fiction, rearranged in chronological order. A couple things struck me about this video.

(in which I bring this blog back to the “safe, uncontroversial” territory of arguing with people who think they can solve NP-complete problems in polynomial time) A few people have aske…
John Maynard Keynes? Paul Samuelson? Winston Churchill? Joan Robinson? Apocryphal?
Ruby Central posted an extremely concerning “Incident Response Timeline” today, in which they make a number of exaggerated or purely misleading claims. Here’s my effort to set the record straight. First, and most importantly: I was a primary operator of RubyGems.org, securely and successfully, for over ten years. Ruby…
See how well you know (or can anticipate) gcc's optimizer. For each question, the left box contains some code, while the right box contains code that purports to do the same thing, but that illustrates a particular optimization.

Recently, I paid $ 12 at Mingtong Digital Mall for a complete phone, featuring quad-band GSM, Bluetooth, MP3 playback, and an OLED display plus keypad for the UI. Simple, but functional; nothing compared to a smartphone, but useful if you’re going out and worried about getting your primary phone wet or stolen.

Unix is a bestiary of ad hoc databases: comma-, colon-, tab- and space-separated tables. Think of /etc/* or /var/log/* , or of columnar commands.
Almost one year ago now, I declared extended validation certificates dead [https://www.troyhunt.com/extended-validation-certificates-are-dead/]. The entity name had just been removed from Safari on iOS, it was about to be removed from Safari on Mojave and there were indications that Chrome would remove it
On 8 June, a Scottish banker named Alexander Fordyce shorted the collapsing Company's shares in the London markets. But a momentary bounce-back in the stock…

I can't sleep. I'm lying in bed every night, and images of Gaza are running through my head. Fathers holding their babies, dead, caked in dust. Bombs dropped on homes [1], on hospitals [2], on schools [3]. Tens of thousands of dead [4] in indiscriminate bombings [5]. Children
Last week I wrote about how Life Is About to Get a Whole Lot Harder for Websites Without HTTPS [https://www.troyhunt.com/life-is-about-to-get-harder-for-websites-without-https/]. Somewhere in the comments there, the discussion went off on a tangent about commercial CAs, the threat
How AI Could Transform the World for the Better
Curious, how’s the refresh rate? Does the e-ink display refresh fast enough to make typing bearable?
Summary: JWCC is a minimal extension to the widely used JSON file format with (1) optional commas after the final element of arrays and objects and (2) C/C++ style comments. These two features make it more suitable for human-editable configuration files, without adding so many features that it’s incompatible with…
A few weeks ago, I attended the Seven Pines Symposium on Fundamental Problems in Physics outside Minneapolis, where I had the honor of participating in a panel discussion with Sir Roger Penrose. T…
How to become an “antischolar” in a culture that treats knowledge as “an ornament that allows us to rise in the pecking order.”
