Fundraising and campaign status (and wiki authentication)?
by Paul Boddie 01 Jul '15

01 Jul '15

I saw a collection of recent updates on the wiki, although the URL in the following page is wrong: http://rhombus-tech.net/fundraising/ Where... https://crowdsupply.com/eoma68/micro_desktop ...should be... https://crowdsupply.com/eoma68/micro-desktop I tried to authenticate myself using various mechanisms in order to edit the page, but... * OpenID didn't work with the Python Package Index OpenID provider * Google have discontinued their OpenID 2.0 support (yes, thanks Google for breaking the Web again!) * Wordpress claimed that I don't own my own username Particularly the last one, but also the first one, sounds more like communications issues between the wiki and OpenID providers. I guess I could register, but I thought it might be helpful to indicate a possible problem. Paul

15in laptop casework progress
by Luke Kenneth Casson Leighton 01 Jul '15

01 Jul '15

http://rhombus-tech.net/community_ideas/laptop_15in/news/ getting there. redesigned the central spar to be more structural support, to help prevent torsion and to give the back edge part something to get its teeth into. a beefy touchpanel holder worked out well for keeping the front edges in place, so this was replicated at the back as well. l.

Any progress?
by Paul Boddie 29 Jun '15

29 Jun '15

Luke, others, Has there been any recent progress on the crowd-funding campaign or on other things? I know there's been a little off-list correspondence about Gratipay, which is peripheral to everything else, but for the benefit of anyone following the list (either as a subscriber or reading the archives) an update might be informative. From what I've seen from following other lists, there's progress on Linux device tree support for various Ingenic JZ-series SoCs, which might have a beneficial impact on any jz4755 card that is produced. My own experiments with the jz4720/30/40 have stalled somewhat for the time being, but I'll get back to them at some point, I imagine. Paul

15.6in laptop casework print started
by Luke Kenneth Casson Leighton 29 Jun '15

29 Jun '15

so after a looong time designing and testing, i began 3d printing the first parts of the full-sized 15.6in laptop casework a few hours ago. the longer edges fit just across the diagonal of a 200x200mm mendel90 with 10mm to spare. the glass is not properly flat but acceptably enough for the part to grip in each corner. the middle strut and back edge are done already, and the left-hand edge is underway. the back edge needs to be re-done already: the smaller "test runs" of the past few months were able to iron out the majority of possible errors however there are still things that need fine tuning. most of the fine-tuning i will leave until i have at least a completed demo which i can assemble around the screen, keyboard and touchpanel. l.

Re: [Arm-netbook] CHIP - The World's First Nine Dollar Computer by Next Thing Co. — Kickstarter

Hello, I managed to receive whole 2 private mails asking for details, so I'm replying to the list, hoping it would be good intermedia between EOMA project news. As a disclaimer, I don't know deep details of 802.11 standard, so someone with more knowledge may find bunch of things to correct. Stylistic otherwise is so it was fun for me to write and fun for you to read. Caveat emptor.

Sure, the end user on a windows machine isn't gonna use it, but > isn't that more effort to block it? You may laugh, but Windows supports that for ages. My random google-up shows this for Windows 7, http://www.firewall.cx/microsoft-knowledgebase/windows-xp-7-8/968-windows-7… , but I won't be surprised if some WinXP update allowed that either. Of course, Microsoft did that years after hostapd https://w1.fi/hostapd/ was available for Linux. Is Microsoft the only commercial vendor brave enough to offer such feature? Certainly no, from a certain version of Android "wifi hotspot" is a standard feature. The technical story which made this possible is: Once about a time there was cute WiFi industry with its WEP security standard. Turned out, that WEP was a complete sieve, and not a security. Well, cute WiFi industry was just happy to sell you WEP2, but turned out, the impact was too big. CIOs didn't want to buy that WiFi thing which could leave them exposed after any vulnerability. So, pundits at IEEE (which are of course guys from cute WiFi industry) sit and thought how to not be laughed at again. What they figured is that they split authentication and authorization out of core protocol (unlike it was with WEP). So enterprises could have better security than a password written on a wall, and most importantly, so they can deliver a promise that if something is cracked, there should be a firmware upgrade, instead of requiring thousands of APs off the walls and replacing with other ones. History is silent regarding the fact whether it was IEEE or some particular vendor was smart enough to figure out that the easiest way to implement those requirements is to make a chip pass complete raw 802.11 packets to outside, and get such from outside - then chip can stay simple (cheap, competetive), and complex and ever-changing crypto can be done in that "outside", like a main CPU user already has. That's the idea behind wpa_supplicant https://w1.fi/wpa_supplicant/ . And surprisingly, ability to pass raw packets has many other interesting uses, like implementing AP mode. And that's the idea behind https://w1.fi/hostapd/ Now, could that not work? Sure, vendor could (possibly) allow only subset of raw packets, or maybe go way of 90ies and WEP and implement it all on chip. Why? Horizontal segmentation. Selling the same chip for $2 without that feature, and for $10 otherwise. Problem: nowadays that's pretty insane. Suppose a user buys an adapter with such chip and tries to enable standard Windows feature of virtual AP. And if it doesn't, it cries in twitters and facebooks "MicroSoft suxxxx!!111". Microsoft doesn't like vendors who do such things to them, and look at them like sh%t. Or someone builds a phone with such chip and comes to Google for Android certification. And they respond: Are you bullocks? A phone can generate only so much 3G/4G traffic. But if we let a notebook connect to it, a lot of traffic will be wasted. Without AP mode, your device simply cannot generate enough revenue for our mobile industry sponsors, so don't waste our time with it. And that's the morale of it - at one point, having a closed system is less beneficial than open, for everyone in the industry - from a user to various types of vendors and integrators. That's what happened to AP mode for a WiFi chip - it's stupid to not support it now. That's what we (subscribers of this list) look for in regard to "mobile" video/graphics drivers, and other drivers of SoC systems. And what Luke tries to drive, too bad he doesn't have same kind of leverage as Google and Microsoft. > > Taken off list because it's not really on-topic, feel free to bring > back. > > On Tue, May 12, 2015 at 3:31 PM, Paul Sokolovsky <pmiscml(a)gmail.com> > wrote: > > Hello, > > > > On Tue, 12 May 2015 18:38:38 +0000 (UTC) > > Derek LaHousse <dlahouss(a)mtu.edu> wrote: > > > >> Alexander Stephen Thomas Ross <maillist_arm-netbook <at> aross.me> > >> writes: > >> > >> > really good marketing and a well made original video. however > >> > they dont give much info like what wifi chipset they use > >> > -weather its software freedom friendly-. > >> > >> From their kickstarter page, it's: > >> - A realtek 2-in-1 Bluetooth 4.0 + WiFi b/g/n > >> > >> Based on that, it's probably an rtl81xx.

KiCAD autorouter freeroute has gone open source and stand alone
by joem 12 May '15

12 May '15

KiCAD autorouter freeroute has gone open source and stand alone For Ubuntu 12.04, install the default-jdk i.e. sudo apt-get install default-jdk The freeroute files can be downloaded from here: https://github.com/nikropht/FreeRouting/ Need to unzip and compile .java files for which there is a script The following needs to be put into a bash script - e.g. compile_freeroute.sh: #!/usr/bin/env bash # # Credits: http://www.freerouting.net/fen/viewtopic.php?f=4&t=255 # (A message written by forum user "foka" on 2014-03-23) # # This has been hacked together in a few minutes after reading the post above. # # 1. Check prerequisites: if [ ! -f /usr/share/java/jh.jar ] \ || [ ! -f /usr/share/icedtea-web/netx.jar ] then sudo apt-get install javahelp2 icedtea-netx-common fi # 2. Compile: if javac -classpath /usr/share/java/jh.jar:/usr/share/icedtea-web/netx.jar \ `find -type f -name "*.java"` then jar cfe fr.jar gui.MainApplication \ `find -type f $ -name "*.class" -o -name "*.properties" $` else echo "*** Some .java file was not compiled. See above" 1>&2 exit 1 fi # 3. Run: java -jar fr.jar Then run bash compile_freeroute.sh and you got stand alone freeroute! :) Related links are these: https://bugs.launchpad.net/kicad/+bug/1290022 https://github.com/32bitmicro/Freerouting http://www.freerouting.net/fen/viewtopic.php?f=4&t=255 Now you can make your own freedom CPU boards and design it with 100% free software and share designs! :) :)
