14 January 2012 - 21:27Santiago – first few days

I’d better log our first few days before the crazyness of signing up to the programme kicks off on Monday. Emily (my fiancée) is also blogging for her TinyEars StartupChile project.

We arrived safely on Wednesday after 18 hours of travel – BA treated us well (reasonably comfy seats and reasonable food). We were hustled into a taxi at the airport (at a rather pricey £45) but got delivered quickly to our rather nice apartments in swanky Providence.

We’ve had three nights of parties now, first with Jon and Anna (so lovely to catch up!), then lunch with Emily’s madrina Johanna (@J_Angulo) and on to meet our padrino Fernando (@fdelsolar), and finally two Phase 1 leaving dos last night. Pisco and rum seem to flow from all bottles. We seem to have found a nice Pale Ale too and London Pride has been sighted in bottles. We got to meet Fernando of SQMOS, the data guys of Junar and Tom of Rentalita (Tom’s Santiago tumblr) along with a whole bunch of others, some of whom are shortly off to travel South America.

Yesterday we climbed San Cristobel (photo) and met a Llama (pronounced ‘yama’). Today we had a nice run along the river at Tobalaba and Kyran has pointed out some other running sites.

Tonight we have another dinner, Sunday we chill (a touch, and prepare a demo), then Mon-Thurs are sign-up days, government ID card days, bank days and demo days all rolled into one lump. The week after we ‘officially’ start on our projects (even if we have launched StrongSteam to our first users already!).

Wifi tip – in the business district there are lots of StarBucks, these have free wifi when you buy coffee.

9 January 2012 - 15:13Heading to StartupChile

This is a quick update – we’re flying tomorrow to Santiago for 6 months of the StartupChile project ($40k funding, no equity, hundreds of projects flying in from all over the world). If you’re interested in taking 6 months to build your own project I’d suggest you take a look at applying to the next round.

Kyran Dale and I are flying out to build our StrongSteam AI and data mining toolkit (its a cloud API with local language bindings). We have our first client and we launched the alpha API to our first testers a couple of days back. Once we’re in Santiago we’ll add some more testers, expand the API and deliver our first project, then after March we can really ramp up the creation of data mining APIs for people to play with. We’re excited to be in talks with a few people about releasing the alpha at a couple of hackday events, it’ll be really interesting to see what people do with our optical character recognition, image matching, face detection and image manipulation tools. If you’re interested in trying out the Python API then do sign-up to the mailing list on the homepage.

Emily (my fiancée) is also heading out with her TinyEars iPad app, she’ll build a child-friendly app that’ll help kids learn to read out loud by using speech recognition to spot errors in their speech. She’ll be looking for testers with iPad 2s and young kids who are learning to read, do get in touch if you’re interested in the testing.

We had a fab sendoff at the Northern Lights a few days back, cheers to all who came along :-)

Finally – I’m a bit honoured to have been selected as a teacher at PyCon in the US in March, I’m running a half-day tutorial on High Performance Computing based on my tutorial at EuroPython. We’re using a bunch of these ideas in StrongSteam, it’ll be great to run the tutorial again.

26 November 2011 - 20:48Five new Brighton businesses

Earlier in the year through Matt Weston a group of us met, funded by the Innovation and Growth Team, to start a peer-group for a set of four (wait for it…) new businesses. The group was successful – and for several of us it led to the realisation that our plans at the time weren’t right. Emily and I were working on SocialTies as our project and trying to find a business hidden in the app, we decided against it and looked to other ideas.

Here’s what we’re working on. I hope it’ll encourage a few other folk to think about building new businesses.

The IGT funding dried up and so we now meet informally, our projects are:

I mentioned that I’d do a little write-up before we leave the country, Chris sent me this blurb about MightyHumble:

mighty humble is a small organic clothing company that believes in creativity, good design and responsible business.  We collaborate with hand picked creative talent to produce unique products using the most ethical and environmental sound materials, manufacturing and suppliers we can find. Our 100% cotton t-shirts are ethically made, certified organic by the Soil Association and manufactured solely using sustainable energy generated from wind power. We envisage our collection as wearable art which enables us to bring the work of some incredible talented people to a wider audience.  For mighty humble business is not just about turning a profit.  Experience has taught us that there’s more too it than that!  We believe a business can (and should) be a creative, fun and positive force.

Jo describeds Bookish as:

the home of unique literary gifts, typographic loveliness and beautiful bookish things – for readers, writers, dreamers, thinkers and bibliophiles everywhere

Jackie says:

Sales Precruitment is all about helping MDs of growing digital and technology companies prepare for recruiting their first (and additional) sales person.  Setting realistic targets, putting measurements in place, interviewing and induction, these are just a few of the things we can help with.  All this is done face to face at present but 2012 is the year I work out how to offer some of this support online… wish me luck!!

From January Emily, Kyran and myself are off to Chile for the StartupChile project, we’re taking TinyEars and StrongSteam as our 6 month projects. A part of our requirement for StartupChile is that we help build the entrepreneurial community – given our work building OpenCoffeeSussex, SheSays, FivePoundApp and GirlGeekDinners we figure we’re well placed to help bring interesting folk together. The opportunity to network with several hundred other folk who have jumped country to found new businesses is simply too good to pass up (along with living in a growing, upbeat country with a strong economy, a new language to learn and some Tango to practice).

For our StrongSteam we’re after alpha testers – we want non-AI developers (particularly web and mobile devs) who want access to image recognition, OCR, data mining and clustering tools. Emily is after collaborators and testers – particularly people with kids and iPad 2s.

26 November 2011 - 18:14Broken economies, an economic thought, freelancer advice

A few of you who know me have caught more than a whiff of my increasingly sour mood over the state of many of our ‘developed’ economies. Between the bailouts of Greece, Ireland and Portugal, Italy about ready for a bail-out, Spain with 22% unemployment who might also need a bail-out (but…the EU packages can’t cover both countries needing a bail-out [scroll down to 'the tower of terror' diagram] – hence the jittery bond markets), Portuguese and Hungarian debt marked at junk status, Belgian‘s credit rating cut (after their embarrassing bail-out for Dexia which had passed #hoho all the stress tests earlier in the year) it is hard to be positive. The Economist and others now cover serious discussion about a possible end to the Euro.

The Economist also notes that there’s a reasonable chance we’re falling back into recession. It seems that end of Jan and Feb for Italy’s next round of bond auctions could make for very interesting events.

In the US Thanksgiving has been given over Black Friday (to get companies back in ‘the black’), this year the event aced all previous years with the deployment of pepperspray and guns by ‘competitive shoppers’ (such a wonderful euphemism! they can camp overnight and use weapons in the name of shopping but Occupy protesters can do neither in the name of protest). This video showing fights breaking out as shoppers try to win $2 waffle toasters brings it home. Still, at least the Super Committee figured out a way to get past the $15 trillion (and growing) debt pile. Oh, no, they didn’t, they just finger pointed and handed the problem back.

In the USA the losers are the private citizens, the winners are the companies. Over the last 50 years corporate profits are up and personal salary (as a percentage of GDP) is down (the key graphic) – if you run a big company you’ll be sitting pretty, everyone else has to work longer and harder just to stand still.

But it isn’t all grim. Interesting conversations are popping up questioning the basis for our financial systems, it is nice to see people try to plot new ways through to stronger economies or point out our too-relaxed view on recent changes. This begs the question – what happens when we can chart the progression of money (because maybe it is signed a la bitcoin), maybe we can penalise money for sitting still (e.g. letting it expire/evaporate)? The idea of enabling both the creation and destruction of money (in the first article) sounds novel, we rarely see money destroyed as a stabilising act (as in – removed from the system entirely) with our established currencies.  Might this force money to do ‘work’ rather than sit in someone’s bank account?

Finally, this brings me to the question of what one should be doing as a freelancer/small business owner. In a companion post (to come out by Monday) I’ll mention that we’re off to StartupChile for 6 months. For me I’m energised at the idea that in Santiago I can meet several hundred other company founders who have all decided to jump country (from all over the world) to expand their networks, help the locals boot-strap a tech ecosystem and build their companies. Taking risks and changing things around seems like a basic requirement for survival and growth in what’ll become a tougher economic environment (talk of a lost decade or two for the Western economies is now quite common).

Prior to applying to StartupChile I’d already started to build StrongSteam, our new AI/data mining product, with my old co-founder from ShowMeDo (our last big project). The goal is help folk create interesting data mining applications and to make my AI Consultancy more visible (just building and talking on it has increased in-bound work referrals by a factor of 4 in the last few months). Being visible and being fresh is absolutely critical to continued success. A couple of years back I’d realised I was getting stale (‘fat and slow’ as I put it) working for a few known clients. I fired myself for 6 months, built the AICookbook project (now defunct, it served its purpose), co-founded SocialTies and kicked myself into a higher gear.

Some takehomes:

  • If you’re not visible enough yet, take some time out and work on open and visible projects
  • If you’ve become stale then fire some clients and work on new challenges (preferably public ones)
  • Get on stage and talk about what you’ve learned, certainly post blog entries sharing what you’ve learned – being visible is key
  • If you’ve got spare time then dive into new projects, don’t wait to become stale (a mistake I made that cost me 6 months!)
  • Join local groups – we’ve got OpenCoffeeSussex here, plenty of tech groups, HackerNewsLondon an hour’s train ride away – meet new people and collaborate
  • Build alliances with companies you like to work with, help them, partner with them

I figure that’s enough with the ranting, noting it down  is cathartic. Now, back to building StrongSteam.

Hat-tip to @umairh as being the main person to open my eyes to the need to question how the world works over the last bunch of years. I’m much obliged to you. @johnrobb‘s resilient community work is also rather interesting.

26 October 2011 - 11:29StrongSteam alpha, HackerNewsLondon, Startup-Chile

I’m a little behind with the blogging so here’s the short version. StrongSteam has been under constant dev for 2 months, we’re close to putting up the first AI tools behind a few Python demos (hopefully it’ll be up next week). I’m talking on this at HackerNewsLondon tomorrow night.

We haven’t (quite) finished the demos so it’ll be a slideshow, I’m thinking of running a workshop in a month or so to show what’s possible, talk through the limitations and possibilities and help people got comfy with the API.

I’m also very pleased to say that we were accepted into the StartupChile programme alongside RadicalRobot (my better half). In StrongSteam Kyran and I will get 6 months in Santiago with a $40k budget (for no equity!) to build our API and this opens the door to further travel. We’re also very happy to welcome Balthazar Rouberol (linkedin) to our team, he’ll be joining us remotely as an intern for 6 months.

Our biggest priority now is to get the alpha out there. If you’re curious to see what we’re doing please follow us via @strongsteamapi and join the mailing list on the strongsteam homepage.

We also have two surveys – the first is so you can tell us about your general AI interest, the second focuses on some of the points raised in the first to tell us more about your needs. We’d really appreciate your input here if you have 10 minutes to spare.

31 August 2011 - 13:24strongsteam – an “AppStore for A.I. and data mining tools”

Kyran and I are starting work on a new project – strongsteam offers a web API with artificial intelligence and data mining tools. The goal is to make it easy for you to do things like:

  • get the text out of images using optical character recognition
  • determine whether two images look the same and if one object (e.g. a certain book or a can of coke) can be found in another
  • use natural language processing to analyse, cluster and compare text
  • extract text from audio (e.g. to pull out keywords from podcasts)
  • use machine learning on text to derive new data

If you’d like to join the closed alpha then visit strongsteam and add your email to the announce list on the homepage.

We’ve started with Python bindings which make it easy to talk to the strongsteam web service. Initially we’ll wrap open source tools that we’ve used along with lots of our own A.I. data mining tools from years of work in my Mor Consulting A.I. consultancy.

At EuroSciPy last week I demo’d using O.C.R. to extract the words from plant labels at Wakehurst Place gardens so you can lookup the plant on Wikipedia once you’ve taken a photo like this one:

Plant label for Ostrich Plume Fern at Wakehurst Place (Sussex)

Now we’re looking at applying O.C.R. to conference name-badges, this will be a bit of a mash-up from data used in our SocialTies conference app and Lanyrd.com‘s data. Next we’ll look at image matching and some text processing tools.

11 August 2011 - 15:08Closing The Screencasting Handbook’s email list

At the start of the year I published The Screencasting Handbook, my eBook on the art of screencasting gained whilst building ShowMeDo and ProCasts. Writing a 129 page book was an interesting challenge, I’m very happy with my early peer-review approach, the book retailed at $39 at first and later I dropped the price to $19 as some of the material has dated.

For the last 5 months I haven’t made any changes but I did keep the emailing list. Now I’m shutting the email lists as there’s little point re-mailing everyone to say that the book is done. Really I should have shut the lists months ago! The Handbook is still for sale of course (at $19USD) and will be for quite some time to come.

Putting this older project into ‘life support’ mode is rather cathartic, now I get to focus on fresh projects like SocialTies (now in iPhone and Android app stores) and our forthcoming StrongSteam ‘Artificial Intelligence web service’.

5 August 2011 - 12:23Social Ties now available for UK iPhones and any Android

This is just a quick post to say that we’ve released the iPhone build of Social Ties to the iTunes app store in the UK. Currently it only supports UK events so we’ve limited it to the UK AppStore, international events will follow later. The latest features include Bookmarking of people you’d like to meet and a Met button to mark the people you’ve already met. As noted today by a couple of users:

Yay now I can know who I should talk to at a conference and everything about them. Thanks @socialtiesapp http://bit.ly/rhka9U@juliancheal

Very impressed with the new @socialtiesapp for iPhone and Android. One to recommend to @briankelly I think! – @eventamplifier

Yay! @socialtiesapp is out on the iPhone and I’m unexpectedly famous! (see screenshots) – @bensummers

The Android BETA has been linked on our Social Ties homepage for a month, we’ll submit that to the Android AppStore once it is feature-complete to the iPhone build.

Followup updates on @socialtiesapp, you can follow us on @ianozsvald and @fluffyemily. If you want customised A.I. for your own project then talk to me, if you’d like mobile apps then talk to Emily.

2 August 2011 - 11:57Dell E6420 with Ubuntu 10.10 (Maverick Meerkat) 32 bit

Having hacked away with Natty Narwahl for a few weeks I’m regressing to the 10.10 distribution provided by Dell here. Installation took 20 minutes, it allowed me to use the previous ext4 partition (I had to edit it using the advanced configuration and set the ext4 partition’s mount point from blank to ‘/’). I formatted the partition too for good measure. I made sure to reload the package list (via Synaptics) and let it fetch updates.

Running ‘uname -a’ reports that this is 32 bit: “Linux ian-Latitude-E6420 2.6.35-30-generic-pae #54-Ubuntu SMP Tue Jun 7 20:28:33 UTC 2011 i686 GNU/Linux”

Next I followed the instructions here to get access to sound and the touchpad (on the fresh install the ‘pad worked but had no side-scroll, now it has side-scroll). I used my previous instructions to get the edgers version of the NVIDIA drivers (not the ones on the Dell site), Optimus was already disabled and the NVIDIA drivers ‘just worked’. I had to install the Dell sound driver but then it also ‘just worked’. Flash with sound seems to have worked out of the box too.

Wifi was a pain – the Dell links didn’t work but downloading this (in Synaptic – the pae version) via this for my Broadcom BCM 5800 (ID: 0a5c:5800) gave me wifi on a reboot. I’ve also upgraded Firefox 3 to 5 via this.

Suspend and hibernate seem to be stable (unlike before with the 11.04 install – it randomly got stuck and lost my desktop). Rather pleasingly although I was getting a gig of Dropbox over Wifi and compiling new sources the battery tool reported 6 hours of battery life (which seemed true-ish, maybe 4 hours would have  been right, though I did have the screen on darkest as it was very late in the night). This beats the max 2 hours I got before with 11.04.

Overall regressing to the 10.10 build from Dell seems to be the right move. Update two weeks later – using the Dell image is definitely the right thing to do, everything ‘just works’ like it is supposed to. I get 4-6 hours battery life using the NVIDIA graphics card as my primary display.

Update – I’ve uploaded a modified script that disables the touchpad for a fraction of a second when you’re typing. This is necessary as the ALPS touchpad identifies itself as a PS/2 mouse rather than a trackpad due to proprietary drivers. The script is in my github repo as Dell_E6420_Touchpad_AutoDisabler. It contains minor fixes from Philip Aston’s excellent version here.

Update (Nov 2011) – Having used 10.10 for 2 months I’ve got some problems that I’ll list.

  1. About 1 in 20 lid closes do not cause the suspend behaviour to start. The result is that the laptop stays ‘on’ with the lid shut. After an hour it tries to go into (I guess) hibernate, for some reason it gets stuck. Next it gets hot, the fans run on full and after a while it is cooking at 80 degrees in my laptop bag, merrily eating the battery. If I get it in time I can open the screen – the backlight is on but nothing responds and I have to force power-off (holding the power button for 5 seconds). If I don’t get it in time it just kills the battery. Upon a reboot it boots a fresh session and everything is fine, sans all the previous session info (this hasn’t yet led to corruption)
  2. About once a month the machine freezes during use. It has happened just after a clean boot (after logging in, before doing anything). It has happened after days of use and many suspends. The behaviour is a total system lock, the screen doesn’t update, no mouse etc. A force power off is required.
  3. The in-built camera normally works with Skype, sometimes it fails to start and a reboot is required. The picture is grainy and doesn’t cope with low lighting conditions (I haven’t tried this on Windows). Using an older Logitech QuickCam Pro 9000 I get a bright, clear picture even in low light conditions for Skype.
  4. Power usage with the NVIDIA card on (Optimus off), using VirtualBox, with wifi and a bright screen is about 3 hours.

It is hard to know if this is a hardware fault (the BIOS-based self diagnostics which run for 30 mins report no problems) or a software fault. I’m inclined to think it is 10.10 and/or the Dell changes. I’m planning on trying 11.10 next in the hope that the SandyBridge chipset is better supported.

My take-home message so far is that if the manufacturer doesn’t support your OS (Dell only partially support Ubuntu), don’t buy from them. I believe HP might have been a better purchase.

25 July 2011 - 9:42High Performance Python tutorial v0.2 (from EuroPython 2011)

My updated High Performance Python tutorial is now available as a 55 page PDF. The goal is to take you on several journeys which show you different ways of making Python code run much faster (up to 75* on the CPU, faster with a GPU).

This is an update to the 49 page v0.1 I published three weeks ago after running the tutorial at EuroPython 2011 in Florence.

Topics covered:

  • Python profiling (cProfile, RunSnake, line_profiler) – find bottlenecks
  • PyPy – Python’s new Just In Time compiler, a note on the new numpy module
  • Cython – annotate your code and compile to C
  • numpy integration with Cython – fast numerical Python library wrapped by Cython
  • ShedSkin – automatic code annotation and conversion to C
  • numpy vectors – fast vector operations using numpy arrays
  • NumExpr on numpy vectors – automatic numpy compilation to multiple CPUs and vector units
  • multiprocessing – built-in module to use multiple CPUs
  • ParallelPython – run tasks on multiple computers
  • pyCUDA – run tasks on your Graphics Processing Unit
  • Other algorithmic choices and options you have

The improvement over the last version (v0.1) is that I’ve filled in all the sections now including pyCUDA (there are still a few IAN_TODOs marked, I hope to finish these in a future v0.3). I’ve also added a short section on Algorithmic Choices, link to the new Cython prange operator and show the new numpy module in PyPy.

The source code is on my github page. The original slides are on slideshare too. If you’re after a challenge then at the end of the report I suggest some ported versions of the code that I’d like to see.

The report is licensed Creative Commons by Attribution (please link back here) – I’ll also happily accept a beer if you meet me in person! If you’re curious about this sort of work then note that I offer A.I. and high performance computing consulting and training via my Mor Consulting.

Update – ShedSkin 0.9 adds faster complex number support. I haven’t added it to the report yet, evidence in the ShedSkin Group suggests it gets closer to the non-complex-number version (i.e. you don’t have to do more work but you get a nice speed boost whilst still using complex numbers).

Update (Nov 2011) – Antonio and Armin posted a note which explains some of the slowness in PyPy and show how it is competitive, under the right conditions. Armin also contributed a C version which shows PyPy to run as fast as C (for their chosen configuration).
