A Q&A with AI regulator Ed Newton-Rex

In November last year, Ed Newton-Rex, the head of audio at Stability AI, left the company citing a small but significant difference in his philosophy towards training large language models (LLMs).

Аппаратный антискиммер. Чёрная коробочка, защищающая банкоматы

Приветствую всех!
Думаю, абсолютному большинству сидящих здесь знакомы такие устройства для кражи данных банковских карт как скиммеры. С ними активно боролись (где-то успешно, а где-то не очень), а к распространению бесконтактных карт они тихо и незаметно ушли в историю.
Многие наверняка слышали про специальные накладки хитрой формы на считыватели карт, призванные защитить девайс от установки постороннего оборудования. Но одними защитными пластмассовыми деталями всё не ограничивалось, существовали куда более интересные девайсы, парочка которых попала ко мне в руки.
Итак, в сегодняшней статье поговорим про такой малоизвестный среди обывателей вид защиты банкоматов как активные антискиммеры. Попутно попробуем запустить имеющиеся у меня девайсы и узнаем,...

Setting Up Your EVE Display: A Quick Guide

Have you just purchased one of our Embedded Video Engine (EVE) displays and are wondering how to get up and running? This blog post aims to help users get started with their newly received EVE displays from setting up the hardware to running various demos. Before we jump in, if you have not already, take a moment to read our blog post on FTDI/Bridgetek Embedded Video Engine (EVE) Modules to get an idea of the various functionalities that the EVE makes possible and what makes them so great!

This section outlines how users need to interface an EVE...

Music in the browser or app?

At some point, your inspirational idea for digital music will have to travel from the platonic realm of your thoughts, into either an app or browser. Unless you can luxuriate in doing both, this represents a stark choice.

Gradual migration of IP address/port between servers

I'm a strong proponent of self-hosting all your services, if not on your own hardware than at least on dedicated rented hardware. For IT nerds of my generation, this has been the norm sicne the early 1990s: If you wante to run your own webserver/mailserver/... back then, the only way was to self-host.

So over the last 30 years, I've always been running a fleet of machines, some my own hardware colocated, and during the past ~18 years also some rented dedicated "root servers". They run a plethora of services for either my personal stuff (like this blog, or my personal email server),...

Inside an unusual 7400-series chip implemented with a gate array

When I look inside a chip from the popular 7400 series, I know what to expect: a fairly simple die, implemented in a straightforward, cost-effective way. However, when I looked inside a military-grade chip built by Integrated Device Technology (IDT)4 I found a very unexpected layout: over 1500 transistors in an orderly matrix. Even stranger, most of the die is wasted: less than 20% of these transistors are used, forming scattered circuits connected by thin metal wires.

In this blog post, I look at this chip in detail, describe its gates, and explain how it implements the "1-of-4" decoder function. I also discuss why it sometimes...

iOmega JAZ. Жёсткие диски со сменными блинами

Приветствую всех!
Думаю, даже для далёких от темы компьютеров хорошо известно, что вскрытие обычного жёсткого диска приведёт к стопроцентной его порче. Но, как оказалось, для некоторых носителей есть исключения. Более того, существовали не просто «разборные» HDD, а такие, для которых извлечение блинов и повторная их установка были штатной операцией. Как же такое было возможно? Давайте разбираться.
Итак, в сегодняшней статье поговорим про iOmega JAZ, поистине интересный накопитель, совмещающий в себе свойства сразу нескольких компьютерных носителей. Узнаем, как устроены и как работают такие девайсы. Традиционно будет много интересного.

KLayout and the Sky130 PDK

KLayout and Sky130: Inverter

I have created a small example of how to use KLayout for the layout of a simple inverter and run DRC and LVS for Sky130 in the hopes that it helps others on a similar journey.

You can find the repository with all files and a description in the klayout-sky130-inverter repository.

There are still some issues with the KLayout technology files so make sure to read the workarounds!

Good Luck 😉️
