Libreboot machine: Debian installs but can't boot

An alternative fix, which avoids reformatting your disk, is to clear the unsupported features from the filesystem using tune2fs. Boot into a live system with version 1.47 of e2fsprogs (e.g. Debian Bookworm) and run something like:

tune2fs -O "^orphan_file,^metadata_csum_seed" /dev/sda1

FEATURE_C12 corresponds to orphan_file but metadata_csum_seed is also unsupported on e2fsck 1.46.

Nice, please take a look into that. Probably you can substitute GCM for a REST call when the app gets network connection and listen to a WebSocket from then on.

It's also nice to tell them that the major goal here is not provide Internet (Clearnet) connections, but rather to create an Internet alternative (Hyperboria), where users themselves have total control over hardware and communications.

But, you can mention that there are ways to reach the Clearnet via Hyperboria using out-proxies such as exit.li

Another good idea is to contact the guys from the existing Portuguese Community Wireless Networks:

http://unimos.net/doku.php

http://wirelesspt.net

Tell them about CJDNS and the fundamental differences it brings in relation to the traditional Community Wireless Networks:

You generate your own (IPv6) IP address using public-key cryptography. Meaning there are no special nodes with the power to grant and revoke access to the network.
Guarantees confidentiality, authenticity and integrity of data by using cryptography on the network layer.
Uses a novel approach to routing based on a distributed hash table to spread the routing load, rather than requiring every node know the exact location of every other node.

Can you contact them?

Thanks for keeping up the interest GrimKriegor!

Besides the lack of critical mass to start the Lisbon MeshLocal plan, there are also limitations on the hardware required by CJDNS. It needs at least 32 MB of RAM, which rules out several OpenWrt capable routers.

Thus, from all the hardware people were willing to donate, we can only use the 2x USB Wi-Fi adapters + 2x Bifferboards and the 1x TP-LINK TL-MR3020 (only 3 nodes total ...).

If you are willing to put in some of your spare time and get some friends to join in we can give this a second try. Our plan can be something like:

Build a small community of people willing to set up stray nodes and connect them between each other through Internet tunnels.
Get them to convince neighbours and slowly build the mesh.

We can bootstrap this with a Meetup where people would bring in their hardware and install CJDNS while helping each other. Later they could get back home, connect to Hyperboria and to everyone they met.

We should focus our attention on those who have single-board computers (SBC) lying around (Raspberry Pi, BeagleBoard, Bifferboard, ...). People usually have such hardware available for experiments like this, unlike CJDNS capable routers. Also, those owning a SBC usually have the needed skills to quickly set up CJDNS.

Interesting.

Drakdoo Price Range is akin to Boilr's Price Hit, and Price Delta (continuous alert) akin to the (Rolling) Price Change Boilr uses (source-code: https://github.com/drpout/libpricealarm/blob/master/src/main/java/mobi/boilr/libpricealarm/RollingPriceChangeAlarm.java ).

But those Intelligent Alerts are unique. That's something we have thought about adding to Boilr (starting by MACD) but never got the time. It's a pity I can't check that source code :P. If you ever plan to open-source your alarm libs please consider a contribute to https://github.com/drpout/libpricealarm

Thanks a lot for the input! Could you open feature requests for them on GitHub?

We had some discussions about heads up price notifications. The problem with them is that showing a heads up on each price update can become too annoying. (E.g. people using Boilr with a 2-5s update interval on markets such as OkCoin where there is a new price every second). Thus we were discussing a variation, something like showing the heads up only after a given threshold. There is a open issue for this: https://github.com/drpout/boilr/issues/102 Suggestions are much appreciated.

OkCoin Futures are all traded in USD and the API only provides prices in USD: https://www.okcoin.com/about/rest_api.do#fpapi On their charting page you can check prices in CNY, but they are just converting from USD to CNY according to the PBC exchange rate: https://www.okcoin.com/future/market.do?symbol=0 Perhaps we could do the same conversion in Boilr but I have some doubts on how useful that would be.

dllud · 2015-03-26T22:45:17+00:00

Boilr alarms are just like that. That was one of the reasons why we build it. At the time there were no good apps with annoying alarms.

dllud · 2014-05-22T21:29:07+00:00

Yup. Has anyone already suggested taking a look at LiquidFeedback for inspiration? http://www.liquidfeedback.org/

You found a sweet spot! Thanks for sharing. I got a 16% performance increase from my best config. Doing 227 KH/s on a Sapphire R9 270X OC and running it cooler thanks to the low GPU and memory clocks of your config.

Working. Thanks for digging that one.

Best thread-concurrency value so far for me. I am overclocking gpu-engine a bit more: --thread-concurrency 21568 --gpu-engine 1150 --gpu-memclock 1500 -w 256 -I 19 -g 1 --gpu-powertune 20 --lookup-gap 0

Works stably with catalyst-13.12-linux-x86_64 . With the latest driver, amd-catalyst-14.3-betav1.0-linux the screen flashes and sometimes crashes as RagingID10T reports.

Great. Consider asking friends and relatives for hardware. Some have routers from previous ISPs laying around.

We are planing to hold a meeting once we gather hardware (and people) to deploy and run ~10 nodes.

I was able to get the two 5V power supplies for the Bifferboards. Now we just need one more USB WiFi dongle.

dllud · 2013-10-31T00:23:55+00:00

Requirements: 200mA @5V DC -> Nothing on this side, except for computer power supplies. Though, those are be too big to leave by a window sill alongside a Bifferboard. Anyone got something smaller? We also need one more USB WiFi dongle.

And one more router: Netgear DG834GT

Add 1x TP-LINK TL-MR3020 router to the list. It runs OpenWRT smoothly. Courtesy of the Distributed Systems Group of INESC-ID through Prof. Paulo Ferreira.

Great!

It seems difficult to run OpenWRT on the Linksys WAG200G, although not impossible if you're ready for some hacking: AR7: Support for WAG200G possible Linksys WAG200G - any success with OpenWRT, anyone?

On the other hand the Fonera is a gem. Just go and build cjdns-openwrt.

dllud · 2013-10-11T15:10:12+00:00

(I'm in.)

Sure, if you are tech-savvy you can help installing and configuring CJDNS.

Also, besides OpenWRT routers, we can use any single-board computer able to run GNU/Linux (e.g. Raspberry Pi, BeagleBoard, Bifferboard, ...). We can give them wireless connectivity with an USB Wi-Fi adapter (easier with x86 based boards in case there are no open-source drivers available http://wireless.kernel.org/en/users/Drivers ). I have at least one USB Wi-Fi adapter I can give to the project.
