Icarus with cgminer mining pool compare (deepbit VS p2pool)

By Xiangfu Liu

Connect to deepbit: ~180 Shares/Hour
Connect to p2pool : ~150 Shares/Hour

The networks is 2MB ADSL, cgminer running under TP-LINK WR1043ND router with OpenWrt system. Icarus connect to TP-LINK WR1043ND USB prot.

Why p2pool is slow which V3 bitstream of icarus:
P2pool’s idea of a “block” changes every 10 seconds instead of 10 minutes, on p2pool you have on average 10sec to do work, so if you doing U:3/m then it takes 20sec to do the work. the block changes in that time so you’re never working on the current block, this is a big problem.

Our Privacy

By Sean Moss-Pultz

I’ve been reading a lot of Andy Grove lately. This quote, from an older Esquire interview, is particularly prophetic:

Satisfying a customer should always be the primary goal of a business. It genuinely saddens me to learn of companies spending more time thinking about what they, rather than you, can do with your data.

Trust: So hard to build, yet so easy to destroy.

Coming back from FOSDEM

By Michael "mickeyl" Lauer

After having skipped FOSDEM in 2011, I wanted to go this year, especially because of the Golden Delicious stand where we had the OpenPhoenux GTA04 on show. A lot of people came around and were excited that someone picked up where Openmoko had left in 2009. The GTA04 is the true successor of the FreeRunner and I strongly invite all of you to support this movement by buying one. You will not get a more open mobile phone anywhere else.

I know that Brussels is always a bit colder than Frankfurt, so I tend to carry appropriate clothing… what I didn’t expect though was that it was frickin’ -20 on saturday. I have never been freezing more in my life. Lets cross fingers that I won’t come back home with a cold. Especially due to the crazy public transportation situation. The Deutsche Bahn managed to accumulate a one hour delay on my way to Brussels – that’s ok, however they managed to crash the engine in Aachen on my way back. So badly that we had to switch to a regional train and switch again in Cologne. Man… *sigh*

On to some good news… another thing I didn’t expect was kind of an Openmoko family reunion. It was amazing to find Jan Lübbe, Stefan Schmidt, Daniel Willmann, Harald Welte, and even Rasterman hanging around at FOSDEM. That was just great. I also happened to share my hotelroom with Boudewijn which was unexpected but again very cool.

So despite the freezing, it was a great FOSDEM for me and I’m looking forward to go again next year, perhaps bringing Sabine and Lara Marie as well.

GTA04 Installation Guide for SHR

By SlyBlog

GTA04 Installation Guide for SHR

This is a step-by-step guide, which should get you from zero to a working SHR on your GTA04 in just a few minutes.

Getting the files

Preparing the microSD card

Your microSD card needs to have 2 partitions. One for the bootloader and one for the rootfs and the kernel:

Furthermore, it needs to be formatted with: 255 heads, 63 sectors/track.
To get this right, you can easily use this script: omap3-mkcard.sh

sudo ./omap3-mkcard.sh /dev/mmcblk0

Installing the bootloader

To install the bootloader, you have to copy the 1st stage bootloader (MLO), 2nd stage bootloader (u-boot.bin) and the bootscript (boot.scr) to the “boot”-partition.

It is important to copy the 1st stage bootloader (MLO) to the microSD card as the very first file.

cp MLO /media/boot/MLO
cp u-boot.bin /media/boot/u-boot.bin
cp boot.scr /media/boot/boot.scr

Installing SHR

To install the SHR image, you have to untar the image you downloaded to the “rootfs”-partition.

tar xzvpf shr-image.tar.gz --numeric-owner -C /media/rootfs

First boot

After you cleanly unmounted the 2 partitions and put the microSD card back into the GTA04 you can boot SHR.

A first start wizard will pop up, which let’s you choose between some options.
Be aware to choose a scale factor of 2.0 when asked. Other than this you could just keep the defaults.

Installing Firmware

If you want to use the WiFi/Bluetooth chip, you have to use a non-free firmware from Marvell.
To get it you have to install linux-firmware-sd8686.

opkg install linux-firmware-sd8686

Congratulations

You successfully installed SHR on your GTA04.
For further information or if you have any issues, please consult the SHR wiki.

My sound hardware didn’t vanish, honest

By Andrew Cowie

I’ve been having intermittent problems with sound not working. Usually restarting (ie, killing) PulseAudio has done the trick but today it was even worse; the sound hardware mysteriously vanished from the Sound Settings capplet. Bog knows what’s up with that, but buried in “Sound Troubleshooting” I found “Getting ALSA to work after suspend / hibernate” which contains this nugget:

Huh. Didn’t know about that one. But seems reasonable, and sure enough,

$ /sbin/alsa force-reload

did the trick.

That wiki page goes on to detail adding a script to /etc/pm/sleep.d to carry this out after every resume. That seems excessive; I know that sometimes drivers don’t work or hardware doesn’t reset after the computer has been suspended or hibernated, but in my case the behaviour is only intermittent, and seems related to having docked (or not), having used an external USB headphone (or not), and having played something with Flash (which seems to circumvent PulseAudio. Bad). Anyway, one certainly doesn’t want to kill all one’s audio-using programs just because you suspended! But as a workaround for whatever it is that’s wrong today, nice.

New OsmocomBB RSSI monitor firmware

By Harald "LaF0rge" Welte

Jolly has been hacking up a nice new RSSI monitoring firmware application for OsmocomBB.

I let the pictures speak for themselves:

I really hope this trend continues and we'll get some actual user interface in OsmocomBB at some point this year..

OP25 project joins hosting on osmocom.org

By Harald "LaF0rge" Welte

Some days ago, I noticed that the famous OP25 project (a Free Software implementation of the APCO25 system, a digital trunked radio system) was no longer reachable on-line. It seems they were running this on a desktop PC in a university. As nobody in the project still seems to be at that university, a change in the network configuration had accidentally rendered the website unreachable.

After some quick e-mails, I offered to host them within the osmocom.org family of Free Software Projects for mobile communications. This is when op25.osmocom.org was created, and a full-site backup uploaded + installed.

I'm really happy that we were able to do a small part to help to make sure this valuable project remains accessible to interested parties in the signal processing and mobile communications field.

Building a Case for the Goldelico GTA04

By SlyBlog

I just came home from my christmas holidays and found a nice, little parcel from Shapeways in my mail box. It contained my first experiment with the Blender 3D software and the Shapeways 3D printing service.

Update: Follow the efforts here: 3D printed GTA04 Case

The Story

A few weeks earlier I started to work on the original Openmoko Neo 1973 (GTA01) CAD files, as found at goldelico.com, with the intention of creating a 3D printable model, which I could print and use as a case for my new Goldelico GTA04 smartphone. To get started I got a Blender 3D crash course by a friend of mine.

First Attempt

As I never did any 3D work before I started with the easiest part – the battery cover:

   

This first prototype was printed using the “White Strong & Flexible” material offered by Shapeways. As you can see on the pictures, this material is a little rough, but still feels nice in the hands. Furthermore I removed the hole at the bottom, as it was pretty hard to design.

The printed part fits nicely on my existing Openmoko Neo Freerunner (GTA02) case, which contains my GTA04 board at the moment:

     

Future Plans

Now, that my first attempt was pretty successful, I plan to further work on this topic, to acquire a full case for my GTA04, so I can use the old case for my beloved Openmoko Neo Freerunner (GTA02) again.
As a next step I’ll modify the Neo 1973′s middle and front parts to be printable with a 3D printer and I’ll probably try to print them using a less rough material, to compare the results.

How you can help

If you like this effort, I’d be happy if you’d go to my Shapeways site (“SlyParts”) and order the first part of your GTA04 case, which will raise 1€ for myself, which I’ll use to order further prototypes.

If you don’t have a Goldelico GTA04, yet, you should take a look at the GTA04 Group Buy Tour, where we collect a batch of 350 orders which will be produced at once, so the price can get squeezed down.

If you ordered a part at my Shapeways site, please leave a comment here about which material you used and how it feels.

GTA04 Free Software Smartphone group buy

By Rui Seabra

There is a successor for the Free Software phone that OpenMoko Freerunner was. While the Freerunner was officially called GTA02, this new successor is called GTA04 and there is a group buy effort going on.

I know the price isn’t very cheap, but we aren’t a big company able to order in bulk hundreds of thousands of devices, if not millions, so 449 € + shipping for the first batch if we get 400 buyers will help get this phone into the hands of some Free Software developers.

Some reasons to buy one of these (the tricky part is having a Freerunner case if you want to use it as a phone):

I would fit somewhere between 1 and 2 except I can’t afford 449 € on this, so I’m kind of hoping for someone circa number 5…

Caring.

By Sean Moss-Pultz

My apologies for not sharing any books these past few months. I’ve been reading on a Kindle. And Amazon, it seems, doesn’t agree that second hand books are worth handing down to the digital age.

There is a tip I’d like to share. Something that has worked very well for me is to identify a writer I love. Read everything they have written. Read what they read. And continue ad infinitum.

For the last five years I’ve pretty much exclusively read fiction. Dostoyevsky to Kafta to Kundera to Cervantas and now Vargas Llosa. But I could not resist reading Isaacson’s biography of Steve Jobs (I highly recommend it!).

Since then I continued with Einstein. And currently Benjamin Franklin. But back to the first two…

Einstein and Jobs are connected in more ways than dying and being born (respectively) in the same year.  I’ve wanted to write about my favorite connection for some time. Since today is the last day of 2011, it probably explains my sense of urgency.

I remember watching Jonathan Ive’s speech at “Celebrating Steve” and being moved to tears by what he said:

But it wasn’t until Einstein’s biography that I started thinking about caring in the large scope of life. Physicist Lee Smolin described Einstein as, “a gardener weeding a flower bed.” He wrote:

Care about what you do. Sweat the small stuff. Charles Eames once said, “The details are not the details. They are the product”. I believe this to my core. My New Year’s Resolution is simple: To care even more.

Happy New Year!

Updated: Openmoko Community Survey 2011

By SlyBlog

Update 9.1.2012: results are updated.

As the year 2011 nears it’s end, we – the Openmoko Community – did a poll [0] about which is the most popular hardware and which is the most popular software in our community. The poll was open for one week now and we got votes from 73 people.

I decided to close the poll now and release the results to the public. To create a ranking I gave 1 point to a “YES” vote and 0.5 points to a “(YES)” vote. The maximum (100%) is 73 points.

Rankings

Software Side:

1. SHR                  112.5 points    (61%)
2. QtMoko                99.5 points    (54%)
3. Debian                75.5 points    (41%)
4. Other Distro          40.0 points    (22%)

Hardware Side:

1. Om GTA02             158.5 points    (86%)
2. Goldelico GTA04       71.0 points    (38%)
3. Nokia N900            34.0 points    (18%)
4. Other Device          26.0 points    (14%)
5. Palm Pre (+variants)  14.5 points    ( 8%)
6. Om GTA01               9.5 points    ( 5%)
7. Google Nexus S         7.0 points    ( 4%)

Conclusion

On the software side SHR is still the most popular distro, directly followed by QtMoko. Quiet a few people commented, that they intend to code their own software/GUI mostly to educated themselves.

On the hardware side the Om GTA02 is the clear winner (which was expected). Surprisingly the Goldelico GTA04 is the 2nd most interesting device in this community, even though very few people have one, yet. Still, most of the developers already own one and you should get yours soon [1], as it seems to become a common target of this community. The Palm Pre, Om GTA01 and Google Nexus S got very few points and thus are probably not worth to support…

Happy New Year

Now, i’d like to wish all you Open Hard- and Software-Enthusiasts out there a good start into the year 2012. I hope the GTA04 project will flourish in 2012 and will help our community to grow and free the phone again!

Poisoning DNS perhaps a bad idea

By Andrew Cowie

This is insane. I’m sitting at a café in Sydney using their hotspot. Went to search for something, and I kept getting strange looking “site not found” pages. Huh? Thy were working a few hours ago. So I started digging.

The café’s upstream ISP is “Optus”, one of the major Australian carriers. To my astonishment I found that Optus’s DNS servers are interfering with Google searches, stealing their DNS lookups and serving results pages on their own (shitty quality) branded search instead! Try https:? No connection; and Google+ wouldn’t load either.

Obviously as soon as realized what’s going on I immediately changed DNS servers to something reliable. Before I did I found a tiny “about this page” link at the bottom of the heinous Optus search results page, where I was told how great this was for me, but how I could opt out of their “default” search engine if I wanted to but was warned this was an “advanced setting”.

Seriously, what do Optus think they’re doing? From a commercial standpoint, do they really think that their captive audience matters to anyone advertising on the web? Of course not, but in the mean time they’re certainly going to alienate customers who just maybe actually do want to use (in this case) Google sites.

There’s a bigger issue, though. Unaltered answers to DNS queries is a backbone of net neutrality. That’s our problem, but once carriers start poisoning nameservers in their own favour it will be but a blink before everyone is doing it to each other and lookups will become worthless. While I’m sure the morons in Marketing who thought that sabotaging DNS queries would be a good idea won’t be worried about the wreckage that will cause for everyone else, such a war wouldn’t be good for any of the companies involved, either. And meanwhile, if they really want everyone to learn how to install an app to “fix” the internet…

Of course, this is only a taste of what we’ll be in for when the communications minister finally gets his compulsory Great Firewall of Australia censorship in place, but one thing at a time. If you’re looking for internet access down here, clearly Optus or anything that uses their network should be blacklisted.

Where Shall I Wander

By John Sullivan

Google Maps is now mapping the indoors. I saw an ad for this while passing through MSP yesterday (given how much time I spend on the Internet, it's strange and a little embarrassing to learn about new things on the Internet from airport billboards), since one of their initial targets is the infamous Mall of America.

Title from John Ashbery

IT has seen a crazy year

By Michael "mickeyl" Lauer

Information Technology has seen a really crazy year. Among all the smaller incidents, the big bangs involved Nokia partnering with Microsoft, abandoning Maemo, HP driving with WebOS against the wall, patent lawsuits everywhere.

What that means for FOSS-lovers is clear… you can’t trust any company to continue working on anything. Business demands are what counts in the world of mass markets. If you want longterm support for a platform, your best bet is to build a community around it. But you will also want to work on hardware support otherwise you’ll run into the next dead end.

To be honest, right now I don’t see much of a future for any mobile Linux-inspired platform other than the mutation called Android. But that’s not much of a problem per se. The smartphone market is crazy. To compete in that world, you have to give up on freedom. But is the mass market really what we want? Is it what mobile Linux needs?

I don’t think so. There are still huge opportunities for using Linux-based mobile software platforms in niches such as machine2machine communication, home automation, research, teaching, and more. That’s where a service-based middleware like FSO comes into the game: for special interests. However, even niche-adoption is hindered without a minimal set of applications. And that is where we still lack: Even special interest people want to use their smartphones to manage contacts, browse the web, send mails, play media, etc. We don’t have an integrated software stack with a complete set of UI applications that would cover these needs. Openmoko worked on one, but failed. Nokia worked on multiple ones, but gave up (multiple times). What else do we have?

With HP’s recent announcement about releasing WebOS as open source, the game may have changed. If we could use the WebOS application stack on top of the FSO middleware, we may have a real chance to get something great and usable – and complete – soon. I have always liked the WebOS UI. If it’s a bit slower than other UIs, who cares as long as it is free?

webOS is going to be OpenSource Software

By SlyBlog

HP the company which bought Palm some time ago just announced, that they are going to release webOS as open source software! The Linux kernel side of webOS was open souce since the beginning, with a few exceptions like the PowerVR 3D driver and the touchscreen driver.
We’ll see how far HP will go and what parts they’ll really open up (their announcement didn’t mention the modem protocol for example).

webOS is probably the best and most intuitive software running on smartphones today. And was said to be “the iPhone killer”. Unfortunately the first device it was sold on (Palm Pre) wasn’t exactly the best hardware as it had serveral flaws like a bad keyboard slider. Thus webOS wasn’t adopted by masses of developers and suffered from a lack of applications, which in turn made it uninteresting to end users.

I got a Palm Pre in the early days and I also got a HP|Palm Pre2 developer device some months ago, which I still enjoy to use. All in all I enjoyed developing for those devices, too, but it was pretty depressing to reverse engineer parts of the modem protocol, to be able to have it communicate with the FreeSmartphone.org (FSO) middleware and run a really free and open source operating system like SHR.

So with this news from HP what we could probably get in 2012 is:

Let’s hope the best for the mobile FOSS community in 2012!

Towards the end of 2011

By Michael "mickeyl" Lauer

Tempus fugit. I can tell you. Even more so, if you have a baby. I must confess I somewhat underestimated the impact the baby would have on my spare time. In some weird mindset I really thought I could continue working as usual on my open source projects… as we know now I couldn’t. I completely lost track and have to catch up with all changes that happened over the last 6 months.

The first bunch of weeks with the baby were really demanding. I mean, really. She screamed a lot and could only sleep in our arms. Boy, were we tired. We carried her around so much we have Schwarzenegger arms now. But it’s great to see her developing, err… growing up, of course. With 6 months now she is a very interested baby, eager to learn new things and always trying to become more mobile.

Luckily both my wife and me are self-employed. It so much easier when you can skip some hours at the usual start of the workday and also at the usual end. Of course, the work needs to be done, so we have to compensate when she’s in bed. But still, it’s very satisfying being able to see her twice a day for a couple of hours — not all families have this luxury. Plus the existence of our two invaluable grandmas… it’s great.

Company-wise, the Lauer & Teuber GbR had an amazing year with many interesting iOS (and some Android) projects. We have reached the maximum we can do with the two guys we are, so we decided to grow and hire our first regular employee who’s going to start in 2012. We also rented another office and are already moving.

I’m slowly getting back into some of my beloved open source projects… it’s great that work on e.g. FSO did not stall at all, but continued while I was “away”. Last week, I attended the 3rd installment of the Open Hard- and Software Workshop in munich, where the latest development of the very promising GTA04 mobile phone was presented. I had a talk about Vala which was well received. By the way, my Vala-book plans are not dead yet… just in parking position

Next week I’m attending the FSOSHRCON, a joined conference with the people working on the freesmartphone.org middleware and the SHR software. It’s going to be great seeing all the folks again, concentrating a full weekend to agree on some important issues laying the path forward for the next year. Can’t wait to be there.

What’s left is the feeling that an extremely busy year has passed by, spiced with incredibly intense emotions. I’m a happy man and I love my life. I’m given exciting opportunities, but also challenges – and I plan to accept everything

All the best to you guys!
