Thirty years ago, in the Hunt for Red October, a software to identify seismic events was used to predict movement of a man-made submarine: https://www.youtube.com/watch?v=y7g6dKncO-I

Thanks for the awesome suggestions. The video port coming out of the Raspberry Pi SoC is HDMI, hence the choice of the connector. We've put the connector on the top of all of our products to lessen the chances of the cable accidentally

A lot of our customers have a background in automation and are used to Windows on their desktop PC, with little prior Linux experience. Shipping a desktop by default is intended to make their life easier. Since the image is based on Raspbia

You mean the watchdog integrated into the BCM2835? That's a good question, we haven't tested that yet, but I've added it to the todo list now. One particular product in the Revolution Pi lineup called "Connect" has

I'm just a kernel dev, not a product manager, but I think a sub $100 product is very unlikely I'm afraid. There are volume discounts though for customers ordering large quantities. Otherwise Accujack's answer is spot on.

We use the PREEMPT_RT patch set available at: https://git.kernel.org/pub/scm/linux/kernel/git/rt/linux-sta... That patch set is slowly being upstreamed into the mainline kernel. We regularly en

We use the Raspberry Pi Compute Module, not the regular Raspberry Pi. The Compute Module is basically a SO-DIMM slot with the BCM2835 or BCM2837 SoC plus eMMC and LP-DDR2 RAM. The Compute Module is spec'ed at -25 to 80°C, versus 0 to 5

True. However these modular gateways are ODVA-certified and have gone through all the mandatory testing (surge/burst, shaker, climate chamber), so they might be the preferred solution in environments where certified devices are require

There's a kernel module called piControl (source code is on GitHub) which periodically polls the I/O modules. The values written to the outputs are taken from a memory area called the "process image". Values read from in

There's a Revolution Pi product coming this year which has WiFi built in (called "Connect Flat", was on display at the SPS fair in November 2019). We used a chip based on Cypress CYW43455, basically the same as on the Raspber

The Raspberry Pi Compute Module built into the Revolution Pi products has an eMMC of 4, 8, 16 or 32 GByte. Each product has a micro USB receptacle via which it can be flashed or mounted from an attached computer. Users are free to use whate

Not anymore, no. We use the "Raspbian with desktop" image as a basis and delete most of the games to make the image fit on the 4 GByte eMMC variants of our products (with about 1 GByte to spare). Customers who don't need a GU

Thanks for this blast from the past. I bought the book in 1997 as a sophomore student at university. My favorite book at the time. Leafing through the PDF after all these years I came across some gems I hadn't appreciated back then: On

Zuffenhausen is now also a mixed ICE/EV factory and EV production has already started there last month. (Porsche is no longer an independent company but merely a VW brand.)

The screen on the frontpage photo says "armv7l". I think that's only printed on the Raspberry Pi 4. The specs say it's a Compute Module 3+, which I'd expect to print "armv7". So either the photo is not gen

Read the full interview. Netscape was owned by AOL back then and the motivation for Gecko was to have an HTML engine that could be embedded in AOL's software. Firefox was just one browser based on that engine, but became the primary fo

It's also worth mentioning that the Firefox team did the same kind of "oopses" to browsers embedding Gecko. See this interview with Mike Pinkerton, who later went to Google to work on the Chrome Mac team: "People will ma

I'm wondering if this is the technology enabling Apple's recycled Aluminium products. The airjet sorter with X-ray detection at 5:27 is particularly crazy.

The Raspberry Pi Compute Module 3 is just that, the SoC of the RPi3 with 1 GByte memory and 4 GByte eMMC on a SO-DIMM module. You need a baseboard though to plug it in. Either the Eval Board offered by the Foundation, or a Revolution Pi if

The desktop in this screenshot is localized to German, hence "Konsole" instead of "console". Also, "Okt" instead of "Oct" as calendar month.
