The hidden JTAG in your Qualcomm/Snapdragon device’s USB port

Back in February of this year, Qualcomm quietly published the source code for interacting with EUD. This is perhaps one of the most exciting things they’ve done lately - especially if you spend a lot of time debugging the kernel or U-Boot - let’s talk about it. EUD stands for Embedded USB Debug: essentially, this is a debug interface built right into almost every Qualcomm SoC since ~2018.

Revisiting Knuth's “Premature Optimization” Paper

The most famous quote from Knuth’s paper “Structured Programming with go to Statements” is this: There is no doubt that the grail of efficiency leads to abuse. Programmers waste enormous amounts of time thinking about, or worrying about, the speed of noncritical parts of their programs, and these attempts at efficiency actually have a strong negative impact when debugging and maintenance are considered.

Many ransomware strains will abort if they detect a Russian keyboard installed (2021)

news.ycombinator.com Unknown 2026-02-21 04:29:55

In a Twitter discussion last week on ransomware attacks, KrebsOnSecurity noted that virtually all ransomware strains have a built-in failsafe designed to cover the backsides of the malware purveyors: They simply will not install on a Microsoft Windows computer that already has one of many types of virtual keyboards installed — such as Russian or Ukrainian. So many readers had questions in response to the tweet that I thought it was worth a blog post exploring this one weird cyber defense trick.

Why Go Rocks for Building a Lua Interpreter

By Roxy Light I recently needed to build a custom Lua interpreter in Go. The exact reasons aren’t important for this blog post, but neither the reference implementation — which I will be referring to as “C Lua” throughout this article — nor the other open source Go Lua intepreters I could find were a good fit for my needs.

Plantaform Smart Indoor Garden Review: Rewarding but Risky

It was about a week into my journey as a hydroponic lettuce farmer when I noticed my Mila air purifier, set to auto mode, was running at full blast. Its internal air quality sensor told me the air was dirty. Not sure if the sensor was overly sensitive, I swapped it out for the more powerful and far quieter IQ Air Atem X (9/10 WIRED Recommends) and set it on auto mode. Next time I went into my son’s room, the Atem was running at its highest speed. I checked the room’s IQAir Visual Pro Indoor Air

Is being bilingual good for your brain?

news.ycombinator.com Unknown 2026-02-20 15:50:19

R eams of papers have been published on the cognitive advantages of multilingualism. Beyond the conversational doors it can open, multilingualism is supposed to improve “executive function”, a loose concept that includes the ability to ignore distractions, plan complex tasks and update beliefs as new information arrives. Most striking, numerous studies have even shown that bilinguals undergo a later onset of dementia, perhaps of around four years, on average. But some of these studies have faile

WASHINGTON (AP) — The U.S. economy shrank at a 0.5% annual pace from January through March as President Donald Trump’s trade wars disrupted business, the Commerce Department reported Thursday in an unexpected deterioration of earlier estimates.
