James Purser: A return to regular podcasting

Tue, 2016-01-05 15:30

I have been incredibly bad at getting my podcasting going again. Apart from one episode of Purser Explores The World (which I need to repush because of the site breakage a little while back) I did absolutely nothing last year.

This is very bad.

So I've set myself a target. Starting on the 5th of February I am going to produce a weekly Lunch Time Science podcast. It will be half an hour long, and have the following format:

  • Introduction
  • News Wrap up
  • Paper of the Week
  • Researcher of the Week

It will stream off the Angry Beanie radio stream at 12:30 Australian East Coast time and then be available in podcast format straight afterwords.

As to the other podcasts, I am still working on how to get them up and running but I'm going to concentrate on Lunch Time Science for the moment.

Oh yes, if you know someone in Australia doing interesting research, or who is interesting and that I should talk to, drop me a line on the twitters, facebook or via email; james AT angrybeanie DOT com.

Rusty Russell: Bitcoin And Stuck Transactions?

Mon, 2016-01-04 09:28

One problem of filling blocks is that transactions with too-low fees will get “stuck”; I’ve read about such things happening on Reddit.  Then one of my coworkers told me that those he looked at were simply never broadcast properly, and broadcasting them manually fixed it.  Which lead both of us to wonder how often it’s really happening…

My approach is to look at the last 2 years of block data, and make a simple model:

  1. I assume the tx is not a priority tx (some miners reserve space for these; default 50k).
  2. I judge the “minimum feerate to get into a block” as the smallest feerate for any transaction after the first 50k beyond the coinbase (this is an artifact of how bitcoin core builds transactions; priority area first).
  3. I assume the tx won’t be included in “empty” blocks with only a coinbase or a single non-coinbase tx (SPV mining); their feerate is “infinite”.

Now, what feerate do we assume?  The default “dumb wallet” fee is 10000 satoshi per kilobyte: bitcoin-core doesn’t do this pro-rata, so a median 300-byte transaction still pays 10000 satoshi by default (fee-per-byte 33.33).  The worse case is a transaction of exactly 1000 bytes (or, a wallet which does pro-rata fees), which would have a fee-per-byte of 10.

So let’s consider the last two years (since block 277918).  How many blocks in a row we see with a fee-per-byte > 33.33, and how many we see with a feerate of > 10:

Conclusion

In the last two years you would never have experienced a delay of more than 10 blocks for a median-size transaction with a 10,000 satoshi fee.

For a 1000-byte transaction paying the same fee, you would have experienced a 10 block delay 0.7% of the time, with a 20+ block delay on eight occasions: the worse being a 26 block delay at block 382918 (just under 5 hours).  But note that this fee is insufficient to be included in 40% of blocks during the last two years, too; if your wallet is generating such things without warning you, it’s time to switch wallets!

Stuck low-fee transactions are not a real user problem yet.  It’s good to see adoption of smarter wallets, though, because it’s expected that they will be in the near future…

David Rowe: Binary Telemetry Protocol

Mon, 2016-01-04 07:30

Last week I tagged along on a Project Horus balloon launch with Mark, VK5QI. The purpose of this launch was to test a new balloon release and telemetry system that uses the closed source Lora chipset. We had an enjoyable day driving about the Adelaide Hills tracking the balloon, then DF-ing the payload on the ground.

The balloon also flew the RTTY based telemetry system. To receive the RTTY telemetry I used the fsk_horus.m FSK modem developed in October. This modem has near ideal performance in converting radio signals to binary digits. However its performance is limited by the RTTY protocol.

On the way home Mark suggested we fly another balloon in a few days, and we decided to try a new, binary protocol with the ideal modem. A furious two days of coding and integration ensued, but we managed to develop a Horus Layer 2 protocol in C, get it running on the payload, and integrate with the HabHub tracking system.

On Saturday 2 Jan 2016 we launched and it worked really well! Here is a plot of the balloons path:

Even with a very weak signal (we could just hear it on the SSB radios), the binary protocol was pulling packets with valid checksums out of the noise. Here is the telemetry from this sample of the received signal we recorded from the Mt Barker home of VK5FJ:

The payload is transmitting RTTY and binary packets. The lines starting with “HORUS” come from the RTTY protocol. The lower lines starting with “1″ from the new binary protocol. The binary protocol was delivering packets at Eb/No as low as 6dB (SNR in 3000Hz of -9dB) at 100 bit/s.

Here are some packets from the very end of the flight, from a sample provided by VK5EI in Adelaide:

The payload was 300km to the East, and disappearing behind the Mt Lofty ranges as it descended beneath 7700m. Once again RTTY at the top, binary at the bottom. In this case RTTY managed to decode the last packet. The following plot helps explain why:

This is a plot of the output energy from the two FSK filters inside the demodulator. The gap between them is a measure of signal quality or SNR. The x-axis is the time in “bits”, there are 100 bit/s. At the start of this sample, the signal is very clean. Then at about bit 25000 it disappears abruptly into the noise, and by bit 26000 it is gone. One thousand bits is about the time it takes to send one RTTY and one binary packet. Once the signal is gone completely, neither protocol can do much with it.

Overall, a very satisfying result, especially on top of the “ideal” FSK modem development from October. I feel like we are pushing the art of open source telemetry forward. While useful and fun for balloon work, this work has far wider applications, such as IoT.

Protocol Design

Mark provided a packed binary structure for the payload data. I put some thought into the protocol design, carefully considering the use case. This is a lesson I learned from FreeDV – where “voice is not like data”.

I realised that with balloon telemetry data, losing a few packets is OK. When floating along at high altitude the last packet is often very similar to the next one. However it is really important to get some packets through. We don’t want the link to fall over entirely, but can tolerate a high packet error rate.

However when the payload is descending rapidly and close to the ground, reliably receiving packets every few seconds is important. It gives you a good chance of finding the payload on the ground.

The new binary protocol consists of a 16-bit unique word for finding the start of the packet, 176 bits (22 bytes) of binary payload data, which are protected by a (23,11) Golay block code to give a total packet size of 360 bits.

Given we have a few 100 bits of payload data I estimated a Bit Error Rate (BER) of 1E-3 would give us a fair chance of getting a packet through. Add a rate 1/2 code and we can handle a few % BER. Here is the unit test output:



$ gcc horus_l2.c -o horus_l2 -Wall -DHORUS_L2_UNITTEST $ ./horus_l2 test 0: BER: 0.00 ...........: 0

test 1: BER: 0.01 ...........: 0

test 2: BER: 0.05 ...........: 0

test 3: BER: 0.10 ...........: 10

OK, so it’s correcting (0 bit errors after decode) at random BER up to 5%. The Golay (23,11) code can correct 3 errors in a 23 bit codeword which (IIRC) means it falls over at about BER=0.08. This channel is arguably perfect AWGN – a balloon 30km in the air with a line of sight path to our receivers. So random (rather than burst) errors is a reasonable channel model.

Looking at the Eb/No versus BER curves for ideal 2FSK we get a BER of 0.05 at an Eb/No of 6.5dB. So thats where we would expect our binary protocol to fall over. Which is exactly what happened in our tests.

A BER of 1E-3 after FEC decoding is rather high. Its a region where FEC codes don’t work too well. I compared a rate 1/2 convolutional code at the same operating point. It had the same coding gain as the Golay block code (which is just 1.5dB). So might as well use the much simpler block code.

In fact, I am wondering if FEC helps us at all. We may be better off just sending the binary data at half the bit rate, and getting a 3dB increase in our energy/bit. Or send it twice, then combining the received symbols (diversity). More research required.

As I discovered with FreeDV, FEC is not a panacea. Simply slapping FEC onto your system without considering the requirements is naive.

The RTTY protocol has long packets of about 600 hundred bits and almost no protection from bit errors. So we could argue it requires a BER of 1E-3, which is an Eb/No of 10.5dB. This means our binary protocol has a “gain” of around 4dB. I haven’t confirmed this, but suspect most of this gain is from simply having a shorter packet.

However the real world improvement with the binary protocol was significant. There were many times during the cruise phase of the flight where it reliable returned packets when the RTTY protocol experienced problems. So perhaps there are other sources of bit errors that mean a little FEC helps a lot.

The Horus Binary protocol is implemented in a single C file horus_l2.c. Using #defines, the encoder/tx side can be compiled down to a very small module that will run on a tiny 8-bit uC. It can also be compiled to run unit tests, or as the decoder/rx side for the ground station.

Towards Open Source Telemetry

I’m interested in developing an open source telemetry system in 2016, and think we can outperform closed source systems such as Lora because … open source. In October we developed an “ideal” FSK Modem, now we have experience and good results with a protocol. Here is a work flow diagram for the project:

The fsk_horus.m modem needs to be ported to C, converted to fixed point, and then run on a modest uC which will give us a complete, open source telemetry system.

One important step is some simple, low cost, radio hardware. Not a chipset, but our very own open radio hardware. I have prototyped some of the radio already – and received 440MHz signals using a Si5351, NE602, and a few transistors (block diagram above)

Open Source – When Experts Collide

As our balloon was wafting about South Australia I was admiring the HabHub software. Some web developers really know their stuff and now I enjoy the benefits of that. I have no idea how to make nice web sites.

It dawned on me that what Mark and I are doing is applying our expertise to the physical layer of the system – modems and radio hardware. The web developers, smart as they are, would be amazed by our skills in that area. However we can link our code to theirs in a few minutes – no NDAs, no permission required. No road blocks to our innovation.

I keep seeing (and then demonstrating) large gains in modems – HF digital voice, VHF digital voice, and now telemetry. As I explore assumptions (“you can’t violate OSI model layers”, “you must have FEC”, “Chipset XXX is the best”, “you can’t build your own codec/modem/radio hardware”, “DSP must run on custom hardware”) I find many of them misleading or plain wrong.

In real terms – performance – the incumbent closed source systems have been crippled by the fact they are closed source. Then they tell us “you can’t play there”. Wrong.

Even the RF hardware is now “opening up” – I managed to get a prototype telemetry Rx working in a few hours on my bench. It’s not scary when you know how. Just open up the black box and peer inside. Refuse to accept the black box is all there is. Don’t stop until you hit the laws of physics.

Just like nuclear fusion – push together a few domain experts and a great deal of energy is released.

Further Work

Mark pointed out we need the new modem and protocol into a form usable by end users. We are currently piping a bunch of scripts together written in GNU Octave, C, and python. Fantastic for rapid prototyping but the end users need a cross platform GUI application like fldigi or FreeDV.

The current system sends RTTY/Binary packets one after the other. The RTTY packets take 70% of the time. With just the binary protocol we could get 3 times the packet rate which would improve the likelihood of getting valid packets.

An interleaver may also help, for times when there are burst errors. I have tested an initial version but it doesn’t separate the bits enough. More work needed.

It was unclear if some long strings of 1′s and 0′s were upsetting the fsk_horus.m frequency and timing offset estimators. More work needed to determine if this is a real problem. The interleaver would help, and we could always use a scrambler if it turns out to be a real problem.

Halving the bit rate to 50 baud would give us 3dB, and still an acceptable a packet update rate. Using 4FSK rather than 2FSK gives us another 3dB, so in total that’s an easy 6dB gain. 4FSK is possible to generate using more or less the current payload hardware (you might need two GPIOs bits driving a VCO). In a line of sight channel 6dB is double the range. In terms of transmit power that’s like having 4 times the transmit power. That may be “enough”; at 30km altitude the curvature of the Earth may obscure the signal first before you run out of link budget!

Michael Still: YA-90

Sat, 2016-01-02 07:28
    Ok, so now that I've rediscovered walking to trigs while pursuing my hobby of trying to kill Mr Carden, I am enthused to do some more urban walking.



    The only urban trig I haven't been to is YA-90 on Isaacs Ridge. There are also three geocaches along the way I'd like to collect to. I propose we stage a walk from Isaacs as there's plenty of parking and do this one some evening when its cooler.



    Total distance should be about 4km return, with about 150 meters of vertical ascent. It should take about an hour.




We did this walk on a warm afternoon on new year's day. The walk is pleasant, with plenty of shade for most of the way. In the end we only collected two of the geocaches, as following the ridge line to the third was considered an exercise for another day. A very pleasant walk. A 4.2km walk with 169 meters of ascent.

James Purser: Looking to move to Drupal 8 for Angry Beanie.

Sat, 2016-01-02 01:30

Ever since Drupal 8 dropped (I honestly thought it wasn't going to drop until at least late 2016) I've been looking for a project to test it out. I could move this blog over to it, but I was thinking a bit more adventurously and thought I could have a look at setting up a seperate site for the For Science! show.

Well.

Slight problem.

While core Drupal 8 appears to be solid, the third party module set, especially those that deal with media handling seem to be well behind in terms of development.

Looks like I'm going to have to get my hands dirty and see if I can help some of these modules along.

Specifically I'm looking at the ability to post audio (both mp3 and ogg), host media players (HTML5) and generally be able to serve podcasty type stuff.

Francois Marier: Linux kernel module options on Debian

Thu, 2015-12-31 08:24

Linux kernel modules often have options that can be set. Here's how to make use of them on Debian-based systems, using the i915 Intel graphics driver as an example.

To get the list of all available options:

modinfo -p i915

To check the current value of a particular option:

cat /sys/module/i915/parameters/enable_ppgtt

To give that option a value when the module is loaded, create a new /etc/modprobe.d/i915.conf file and put the following in it:

options i915 enable_ppgtt=0

and then re-generate the initial RAM disks:

update-initramfs -u -k all

Alternatively, that option can be set at boot time on the kernel command line by setting the following in /etc/default/grub:

GRUB_CMDLINE_LINUX="i915.enable_ppgtt=0"

and then updating the grub config:

update-grub2

Michael Still: A year of being more active

Wed, 2015-12-30 10:28
A little over a year ago I helped host a panel session at the Paris OpenStack summit. The panel was three telco people talking about NFV, but that's not the bit I really remember. The bit that really stuck with me was how fat I looked in photos from the event. An example:







I weighed just over 110 kilos (240 lbs). I decided something had to change -- I have a new daughter, and I want to be around to see her well into her life. So, I joined a gym and started bush walking. My first walk was documented here as a walk up Tuggeranong hill. That rapidly became an obsession with climbing hills to survey markers, which then started to include finding geocaches.



I can't give you a full list of the tangents that one photo from Paris has caused, because the list isn't complete yet and may never be. I now run, swim, ride my bike, and generally sweat on things. Its all fun and has had the unexpected side effect that its helped me cope with work stress much more than I expected.



I've lost about 15 kilos (30 lbs) so far. Weight loss isn't really the main goal now, but its something I continue to track.



I thought it would be interesting to list all the places I've walked in Canberra this year, but a simple bullet point list is too long. So instead, here's an interactive map.



Interactive map for this route.



There are a lot more walks I want to do around here. Its just a case of finding the time.

Michael Still: Mount Tennent

Tue, 2015-12-29 08:28
    Ok, so I want to do Mount Tennent from the "wrong" side (Apollo Road up the fire trail). The reason for this is that there is a series of 20 something geocaches along the route that I'd like to tick off as well as walking to Tennent.



    I think the total route should be about 13kms, with about 800m of ascent. I propose we leave at least one car at the Apollo Road car park, and then drive the rest to the start point at the Namadgi visitor centre. We can then do the walk, and send one car back to collect the others while we wait under a tree (or something like that).



    Naismith's rule says this walk should take about 5 hours.




I've been meaning to do this one for ages, but finally got around to doing the walk with a few friends. We went up Tennent from the Namadgi visitor's center, but walked back down on the far side of Tennent which seems less common. The far side is less scenic, but less steep as well I think. Along the way we collected 23 geocaches along the way, and a lovely walk was had by all.



Just over 1,000 meters vertically, and around 16km horizontally.

James Purser: Renting vs Owning, a quick calculation

Mon, 2015-12-28 23:30

So we rent, we always have. Not from any sort of ideological resistance to owning a house or anything, we just haven't been in the position where it's been a thing we could even consider until now.

A new job has put us into a position where we could start looking at the vague possibility of buying a house, committing to a mortgage and so on. So I've been looking around both at the houses available in the area (I like Dapto, I don't particularly want to move), and at the sort of money we would need to be paying out fortnightly.

So to give you a brief run down on what we pay a fortnight, I'll just put it at about $800. This gives us a three bedroom house with a garage, a single bathroom and toilet and a big back yard. Add in the money it costs to travel to the city to work and you could make the case we're paying around $920 a fortnight.

Average rental in Dapto in is $420, so that takes the fortnightly amount up to $960.

Now let's have a look at the buyers market. According to that site, the median house price is $430,918. The current St George 2 year fixed interest rate is 4.19%. According to their loan repayment calculator, this means that our loan repayments would be $1592 for the first two years and $1492 for the rest of the term (depending on which way interest rates go of course).

So, if we do buy a house in this area, we're looking at adding almost half again on top of what we pay at the moment.

Right. 

If we want to buy a house for close to what we're paying for rent now, we have to look at moving south to Bomaderry or Nowra, both of which have median house prices under $350,000. Unfortunately that also means that I would start travelling for six hours a day to get to work and miss 12 would have to pull out of her selective high school and so on.

We still want to buy a house, but right now it's not going to happen. So renting is going to be our thing for a while yet.

David Rowe: FreeDV 2016 Road Map

Mon, 2015-12-28 17:30

About a year ago I posted a FreeDV 2015 Road Map. Time for a review and to make plans for 2016.

Summary of 2015

It was a really good year for me professionally, many goals achieved or pushed forward, and a few unexpected digressions that has opened up interesting new horizons. Highlights include:

  1. The SM1000 FreeDV Adaptor entered production, is selling steadily, and we are now making the 3rd batch. Some encouraging contributions from the community (thanks Stuart for your firmware work).
  2. Some exciting test results using FreeDV on VHF channels (thanks Daniel) lead to the SM2000 VHF DV radio project. I’ve spent the last few months prototyping hardware for this project and Rick, KA8BMA, is now working on the CAD for Rev A. Lots of exploration and development of VHF modems (thanks Brady).
  3. The FreeDV 700B mode was released, using a completely new, very robust, coherent PSK HF modem. This met the goal of open source DV down to 0dB SNR. The weakness of this mode is speech quality – it’s OK for brief exchanges at low SNRs but difficult to use conversationally.
  4. World wide efforts at promoting FreeDV, such as the QSO party (thanks AREG), conference and Hamfest presentations (especially in the US – thanks to Mel and Bruce and many others), the FreeDV Beacon (thanks John), and weekly WIA broadcasts (thanks Mark and Andy).
  5. The Masking and Trellis work (thanks Eric VK5HSE) shows great promise for improved quality and robustness to channel errors.

FreeDV 2016 Road Map

Here are my goals for 2016:

  1. Time for another iteration of FreeDV quality/robustness work. The goal is a FreeDV mode with the robustness of FreeDV 700B but the speech quality of FreeDV 1600. I’d also like address robustness to different microphone/audio/acoustic conditions. This involves a lot of detail work and on air, real world tuning. I’ll call this mode 700C for now, although I have no idea what the final bit rate will be. A higher quality mode for VHF work would also be useful.
  2. Iteratively develop the SM1000, add a USB virtual comm port for configuration, progress the UI, port a 700-something mode, improve internal microphone quality.
  3. Release VHF FreeDV modes, one mode that runs through $60 HTs, another that outperforms closed source DV by 10dB. Integrate these modes into the FreeDV GUI program, FreeDV API, SM1000, and SM2000.
  4. Demonstrate advanced VHF DV features with the SM2000, such as a low cost TDMA repeater, diversity reception, and outperforming analog FM and closed source DV systems by 10dB: on an open hardware/open software platform.
  5. Increase on-air FreeDV activity so it’s easy to find a daily QSO on 20m and 40m, through the FreeDV Beacon, conference and Hamfest promotion, QSO Party, broadcasts, test and tune meets where we help get SM1000s/FreeDV running.

Here’s a work flow diagram of how it all fits together:

Other Projects

Some other (open source) project ideas, not strictly connected with FreeDV:

  1. SDR Direction Finder: A phase based direction finding system that uses a fairly simple RF mixer board (LO+mixer+combiner) to frequency multiplex signals from two antennas into a SDR receiver. I have this partially working on the bench; it can measure the phase shift between the two input ports on the 70cm Ham band. Next step is to connect real antennas and try it with real off air signals. The phase shift can be used to determine a bearing. It’s not Doppler, there is no switching of antennas. The phase is estimated using some AM-like signal processing of the two signals. With two antennas there is a 180 degree ambiguity. If the system works I’ll look into resolving that ambiguity. Would be nice to work with someone on this, it’s kind of a side project.
  2. Urban Noise Cancellation: Like many HF radio users, I am experiencing S9 background noise levels on the lower HF bands. It’s got to be fixed. I have some ideas on how this can be partially canceled using DSP techniques and two or even one receiver(s). None of my friends and colleagues believe it can be done but that’s never stopped me before. Yes I am aware of analog products that attempt a similar approach (e.g. from MJF). This is very different.
  3. Open Telemetry Radio: The Near Space Balloon community are migrating to closed source chip sets for telemetry. This needs to be fixed. In October I showed just how powerful open source modems, as applied to telemetry, can be. I would like to develop an open source sub $10 UHF radio for telemetry. My modem experience suggests we can run most of the radio in software on a micro-controller. Many applications in IoT as well, so this project would lead to “open source” IoT radio hardware.

Note: asking me “when” for any of the above will get you an invitation to help “make it happen”!
