Re: [Arm-netbook] A suggestion why Systemd may be bad

Sorry, I just read your reply Mike. I think that answers any curiosity I had. I appreciate it very much. This is makes sense as I imagine it to be part of the problem GNU/Mach is trying to solve (separating components of the system better, and with more micro-managed permissions?). Anyway, above and beyond explaining, both Mike and Philip.. Thx!

Enough Space in the 15.6" laptop housing for an SSD?
by Mike Leimon 11 Feb '17

11 Feb '17

In light of all the recent discussions about journaling filesystems and system logging on systems with flash storage. I'm a feeling a bit curious to to know if there is enough space within that included "internal" usb cavity of the 15.6" laptop housing to be able to house a small M.2 42mm usb device. I'm thinking about a device like the following: https://www.amazon.com/Crest-NGFF-SATA-Enclosure-SY-ENC25040/dp/B0146DD6KM/ Perhaps if/when there is a rev 2 of the Laptop housing, it might be worth considering the creation and inclusion of an additional board which would both provide a built-in usb to SATA adapter as well as provide a location to install an M.2 SATA drive (with huge bonus points if it can support an 80mm drive). I might be an oddball but, I would also love to see the inclusion of a dedicated M.2 SATA board to the upcoming EOMA68 tablet design (even if there would only be room for a 42mm variant) to be a huge plus. I think that being able to use M.2 SATA drives would be a huge step up in quality from using uSD cards both from a reliability standpoint as well as speed. Also, if USB -> M.2 SATA board created was a USB3.0 device it would pretty much be able to run the SSDs at their full speed.

> So what happens on a violent poweroff? Just lose data? Sure, if you happened to be in the middle of writing to the card, but this isn't that big of a deal really.

passthrough card v0 quick status
by Luke Kenneth Casson Leighton 08 Feb '17

08 Feb '17

assembled here with my friend's equipment, i got the 9161A tab pin wrong (GND instead of power), and i managed somehow to reverse the order of the OTG pinouts 5-1, despite cut/paste from a known working board. after pulling up the 3.3v regulator and putting a top-mount OTG reversed in place of the mid-mount, powerup worked and the GL850G USB Hub came up. tomorrow i will test the tfp401a by... you'll like this... configuring an A20 board to do HDMI output, and wiring it to the passthrough card :) l. --- crowd-funded eco-conscious hardware: https://www.crowdsupply.com/eoma68

Re: [Arm-netbook] TIL: Intel's credit-card sized modular computer is "inspired" by EOMA68

It almost looks as if they don't have money to throw at everything any more. I'll bet they're tightening the strings in anticipation of AMD's comeback. ------ Original message------From: Paul BoddieDate: Tue, Feb 7, 2017 15:22To: Ralf-Peter Rohbeck;Linux on small ARM machines;Cc: Subject:Re: [Arm-netbook] TIL: Intel's credit-card sized modular computer is "inspired" by EOMA68 On Thursday 2.

Their embedded boards don't really seem to have been widely picked up, at least in the hacker/hobbyist mainstream (although maybe the Arduino 101 really has sold well), and what started with a higher-end Arduino competitor employing a Pentium-class CPU (Quark) became a 500MHz Atom-based product (second generation Edison) that has now led to this 1.5GHz Atom-based board (Joule).Paul

USB3.1 pinout
by Internet 06 Feb '17

06 Feb '17

Hey there! I was wondering about the USB3.1 pinout in the EOMA68 standard. In my research on the USB Type C connector I found out that USB3.1 (Superspeed+) has only two differential signal pairs (one for receiving, one for transmitting) but on elinux.org there are four differential pairs for only one USB interface. Are the other two pairs meant to be used by the second USB port or did I miss something? Thank you very much! Julius Lehmann

Re: [Arm-netbook] arm-netbook features

I hope I am doing this right subject wise, I am curious: I was wondering how much battery life do you expect to see by default if you have a web browser like firefox open. I also wondered when the 4gb ram supporting processor will be an option. Is the printed for you version easy to build? and finally I am curious, is it extremely stable? just because it is made partly of wood that makes me curious. fire problem aka...
