Harties Cableway

I first heard of the Harties Cableway when I first moved to Johannesburg - but I was told it was derelict, and no longer operational. About a year ago, while driving through the area - I went past the site on a whim and saw that it was "under construction". Ever since, I have wanted to go up - but just never got round to it.

It's a fixed cable car system, providing a fairly comfortable ride up to the top - with absolutely amazing views of the area - with Johannesburg just visible on the horizon. The last bit to the top is particularly steep - but the cable car speed is fairly gentle with the whole ride taking about 2 minutes. There are a few food places with very reasonable prices - and is generally, a good place to spend an afternoon. 

  

It is hard to imagine riding up on the older cable car system, which are still on display at the bottom.

 

JPO's 1st 2014 Season, 2nd Concert

For a pair of concerts that precede Valentine's Day, most of the music was rather a reflection of broken hearts instead of love and happiness. And all the music was Russian - although there wasn't a link between the nationality and the somberness of the music! Daniel Boico was back (for this week only unfortunately) as the conductor, and, once again he brought great energy to the performance.

The concert did start off brightly - Borodin's Polovtsian Dances from Prince Igor. It's a great piece - especially the solos featuring the oboe and the clarinet. It was a great start to the concert. The concerto, featured German cellist, Peter Bruns, playing Shostakovich's 2^nd Cello Concerto. The cello, by default is quite a somber instrument, and the piece itself, was quite somber - even when there was some fanfare or brightness - it seemed to be quickly extinguished.

The final piece, was Tchaikovsky's 6^th Symphony - Pathetique.If there is one piece of music that traces the journey from happiness to sadness and despair - this is probably the best candidate. It even has a great flourish that promises happily ever after, at the end of the 3rd movement; to be brought crushingly down to despair in the final movement.

It was not the best Valentine's Day concert (but then again, it wasn't advertised as such) - but it was still a great concert with superb performances all round.

Lang Lang and Metallica

It is not the first time that Metallica has merged metal with classical, but the collaboration with Lang Lang at the Grammy's is just mind blowing - not only how Lang Lang perfectly fits into the metal performance guise; but also how well the piano merges with a Metallica classic.

Rome2rio

I have been planning my next trip the last few weeks, and a new website - Rome2rio - has been an amazing help for working out travelling options. Combining the full set of bus, taxis, public transport, flights and ferries - it has been a great help in working out the best way to travel between two points - especially when my trip covers quite a wide set of cities in a constrained time period. I have been most impressed by some more off beat suggestions it has thrown up; things that even some tourism sites and travel companies don't mention. Definitely one of the best travel planing websites around!

Buskaid Chamber Concert

St Mary's - a private girls school in one of the richer suburbs in Johannesburg is quite an ironic location to host Buskaid - an ensemble from one of the poorer suburbs of Johannesburg. The Edge, a brilliant auditorium with amazing acoustics paints the gulf between the haves and the have-nots - Buskaid is after all still struggling to add on to their music school.

Buskaid returned for the third year running to the Johannesburg International Mozart Festival, playing yet another eclectic mix of composers, spanning a few centuries; ending off with the Buskaid tradition of kwela. For me, the highlight was Tiisetso Mashishi playing Max Bruch's Romance for Viola and Orchestra Op. 85; but all the pieces were well performed, and well received by an almost capacity audience. 

Buskaid performances are always a highlight and deliver some of the most joyous musical performances on stage. And they definitely deserve to play in the best venues available.

JPO's 1st 2014 Season, 1st Concert

The 2014 concerts for JPO started this week, and for the first time, I decided to get season tickets. For the last few seasons I have managed to go to almost every concert - and the discount makes sense. The seasons have been shortened to 5 concert weeks this year - perhaps it is a cost saving move. The first concert featured conductor Brandon Phillips from Cape Town, and acclaimed pianist Christopher Duigan from Durban - making it an all South African affair.

The concert started with Liszt's Les Préludes, S97 (Symphonic Poem No.3) - which was a bit longer than I expected, with a lot of different moods - which is explained by the origins of the piece. In fact, the entire piece is like a classic story arch - there is a mostly neutral set-up narrative, followed by arguments and strife concluding with celebration and everyone living happily ever after. It's a great piece to start off the year!

Liszt's Piano Concerto No 1 is one of famous piano concertos,easily recognisable, Christopher Duigan played it brilliantly. I think I enjoyed it more than Ben Schoeman's performance in 2011 - but that could be just due to the passage of time! Christopher Duigan's encore (given seemingly quite reluctantly, after the 3^rd round of applause), was a Liszt transcription of a Donizetti opera - was amazing; and got an equally appreciative applause.

Dvořák's 6^th Symphony rounded off the evening, and of the evening, my least favourite. To me, it just didn't seem to fit in with the rest of the concert line-up.

Movie: The Book Thief

Set during World War 2, the story revolves around an adopted girl, Liesel, (it is not completely clear why she is adopted) in a small German town, and the experience of war. Her adopted family hides a Jewish family friend for 2 years, she teaches herself to read - and then falls in love with literature. It is a chronicle of the times where nationalistic songs included hatred of the "non Germans''; where books are burnt and where jobs are dependent on Nazi party allegiances. 

The use of "Death" as the narrator was a stroke of genius in part; spoilt by an annoying voice and some cliched lines. The mangled use of German words in an otherwise English movie is also sometimes annoying; but the story and the acting performances are impressive, especially by Sophie Nélisse as Liesel.

It's a different take on the World War 2 movie - not focused on the politics or the fighting - but rather on the lives the women and children that aren't on the front; and not in the major cities. It's a touching tale of will, hope and bravery; and well worth watching.

Movie: The Wolf of Wall Street

Despite its many excesses, The Wolf of Wall Street doesn't feel like a long 3 hour movie. It is fast paced, with a dramatic tale of drugs, alcohol, money, sex and greed, based on the life of stockbroker (now turned motivational speaker and sales guru) Jordan Belfort.

The movie features some amazing acting performances - especially by Leonardo DiCaprio and Jonah Hill; and while it does tell the tale from Jordan Belfort's perspective; the impact of the pump-and-dump stock trades is not really explored. Instead, the FBI investigation comes across more as inevitable the fall of the anti-hero rather than arising from actual complaints from harmed consumers. 

Nevertheless, it is a highly entertaining movie, that deserves the rich haul of award nominations (and wins).

Viennese New Year‘s Concert

The opening concert of the Johannesburg International Mozart Festival, was effectively a tribute concert to the Viennese New Year's concerts - a concert with a lot of light, happy music. There were a lot of polka and waltzes (many penned by a Strauss), a few operettas (one even penned by Mozart) and a few other well known highlights. 

One of the great things about Richard Cock as a conductor in these types of events, is how he gets the crowd involved and informed - be it little snippets on the pieces about to be played, or getting the crowd singing or clapping along. It certainly makes these concerts a lot more accessible; than the typical classical music concerts.

Talking and Feeling Plants

One of the main arguments made by vegans and vegetarians supporting their food choice relates to not causing animals pain. The argument is quite compelling, especially given many modern, high volume, farming methods - but it is usually hypocritical, in that the defence of animals rarely extends to insects and other less "cute" animals.

Some recent studies now seem to close down the argument on plants not feeling pain. The Economist has a very interesting article reviewing work showing, experimentally, that not only do plants feel pain, but they also have the capacity to remember the circumstances when they felt pain. Another article in Wired, had a discussion on plants communicating warning between each other - although this was restricted in terms of location and species of plants. 

This is quite interesting beyond just the concept of plants being sentient (although I think Ents are a bit far off). It extends our own understanding of what biological constructs may exist for nervous systems - and that the traditional known nervous systems are not the only ones. Perhaps, in one of the planets out there, there is a sentient species that are just like Ents :)

Why the e-tag?

I first heard about the Gauteng Freeway Improvement Project in 2008 - and that included a fairly detailed discussion on how the project was going to be paid for - tolling. The discussion document, compiled by a senior manager at a large construction company, provided views of the work packages, proposed designs for new interchanges, the proposed timelines for the work and the proposed toll fee of 50c per KM.

I don't like the idea of tolling - but in my opinion OUTA's (and for that matter COSATU and the DA) actions were largely misdirected. Tolling came across, because of a single failure - politicians across the board (from every party) - be it local government, provincial government or national government - not doing their jobs. It is after all their responsibility to vet proposed actions, such as road improvements. And the tenders were all public documents; well advertised - the people who were elected to look after such things, didn't. And a few years after the projects were awarded, it became a hot button issue.

While a lot has been made of the tolling process - one of the questions I haven't seen being raised, is why the e-tag? Let's take the system without e-tags; which is fully functional whether you are registered or not. When a car goes under the gantries, the license plates are captured; and the number plate is deciphered. If the number plate is linked to a registered account, appropriate discounted charges are calculated and deducted from the account. If the number plate is not linked to a registered account, the charges are compiled; and after a certain period of time, an invoice is sent through based on the vehicle registrations details.

So what value does the e-tag add? Firstly, it is not necessary to get the discounted rates. Secondly, it is not transferable - it can only be used with one vehicle. It does not help with unlicensed vehicles - since those vehicles can't get e-tags anyway. In fact, the only benefits I can see are 1) the double-beep to tell you that the account is getting too low and 2) reuse in other toll roads that support e-tags (which don't have cameras). People who use the roads covered by earlier verision of e-tags regularly, already have e-tags - and the use case is easier to defend - pay on the spot, or use an e-tag. That doesn't extend to open-road tolling.

But the whole e-tag infrastructure adds additional cost; additional RFID readers, additional tags, the whole registration process etc. Instead, a more rational process with open road tolling would have been to simply issue accounts -  just like the municipalities do - and provide discounts for early payment, and penalties for late payment. And just like any credit process, provide for debt collection. Registration or pre-paid accounts can also be handled through the same process - but just adds extra administration overhead. 

Instead, with the added complication of registration and e-tags, SANRAL has gotten itself lots of headache and delays - with absolutely no additional benefits.

Movie: Carrie

I have not read Stephen King's book, nor have I watched the earlier versions of this movie. Carrie, a quiet and reclusive teen brought up by her very religious mother (brilliantly portrayed by Julianne Moore), gets bullied in school, discovers that she has telekinetic (and other) powers (naturally from the devil), and has a meltdown that takes out the whole school when the bullying goes overboard. It's better than most teen (or is it young adult?) movies and good entertainment; but nothing spectacular.

Movie: Jeune & Jolie (Young and Beautiful)

The plot is fairly simple - a young woman (girl?) looses her virginity, but doesn't enjoy the experience - during her summer holidays. Back home, she becomes a secret call girl - mainly catering to rich, old men; where she experiences a wide range of sexual activities - although; except for one "john", she doesn't ever seem to actually enjoy the experience.

The movie makes no moral judgement (though it does present various sides of the arguments around prostitution) - neither does it present any motivation on the choice of becoming a prostitute. It is like a study of a rebellious teenager - but one that doesn't draw any conclusions, nor offers any theories. 

And, in that respect, the movie was unrewarding.

Is it worth it?

In Bruce Shneier's TED talk from 2011, he comments that the critical question on security is "is the tradeoff worth it?". In the whole NSA debate, there has been much written and commented about the programmes, the programmes' impact on individuals' rights to privacy (both American and foreign citizens) and the ethics around such a programme.

However, the question on whether the NSA programme's trade-offs were actually worth it - as in a full cost benefit analysis, has only been tangentially discussed. In this regard, a paper by Mueller and Stewart, provides a good overview of the cost benefit analysis. Even, in the absense of numerical values, the benefits provided by the programme are actually quite low.

The paper is a vital discussion that has, so far been poorly addressed. More than anything else - surely a programme that costs billions, but has very little identifiable benefits, should be seen as fruitless expenditure. Given the US's current political stances on budget defecit - it almost seems like cutting the NSA programmes themselves will address the gap!

New Year's Eve at V&A Waterfront

It has been a number of years since I spent New Year's Eve at V&A Waterfront, and the even has certainly grown. From the  amphitheatre, the musical acts have now moved to a specially constructed stage on Jetty 1. It means more people can be accommodated, but it makes the music far less intimate - with a wide body of water separating the artists from the crowd.

The highlight event is the fireworks, and this year was spectacular. Some of the fireworks made shapes in the sky - an effect I hadn't seen before. There were some other performers around the V&A - the fire dancer was the most interesting.

Da Vinci - The Genius Exhibition

Located at the Chavonnes Battery Museum in the Clocktower Precinct, the exhibition does a great job tracing the many contributions of Leonardo Da Vinci. There are reproductions of his notebooks, with great details on his amazing anatomical drawings; there are miniature and a few full size models of his many machines - including the tank, his gliders and artillery weapons. There are reproductions of some of his most famous paintings - and a very detailed look at the Mona Lisa.

It's a great, and fairly thorough exhibition on Da Vinci's many accomplishments. It is a touring exhibition, and the scope in itself is unique. The only criticism I have, is that there not enough focus on the other art works and sculptures.

It runs until February 2014, and is highly recommended.

Sidewalk Cafe

It's a strange place to have a cafe - quiet, posh suburb - but the location on the slopes of Table Mountain leads to amazing views outside. It is a cross between hippy and yuppie - the healthy drinks, the quirky design - and the patrons mostly seem to be stylish yuppies. The food is great, and well priced - a great place for lunch really.

Franschoek

For some reason, I had never been to Franschoek before today. Famous for its food scene, boasting many of South Africa's top restaurant, it is actually not that far from Cape Town - most trips in Gauteng take longer. 

To be honest, there doesn't seem to be much else, other than food. There are some shops off course, but not I did not find it to be a place to go to do stuff. 

The location is very scenic, and Franschoek pass is a very scenic drive - both for the views of Franschoek on one side, and the rocky ravine on the other. The drive and food are rewards enough.

Kalk Bay Harbour

I love the energy at Kalk Bay harbour - it has a great fishing village vibe, and the wheeling and dealing by the fishing folk as they sell their freshly caught fish is great to watch.

DW-11-13

DW-11-13 was rated by Eat Out as the best restaurant in Gauteng; and P and I have been meaning to go there for quite a while. With P moving back to the Western Cape, we finally went round to going to DW-11-13 for lunch. While the food is expensive, it was not significantly more than some of the other good restaurants I have been to in Johannesburg; and food was substantially better and is well deserving of its accolades. In particular, the desserts are amazing - and in fact, it is worth going to DW-11-13 just for the desserts.

Movie: Ender's Game

Visually, Ender's Game is magnificent; from the zero gravity fights in the Battle Room to the final space battles; it is a visual feast. Unfortunately, the soul of the book is pretty much taken out - the main story arc is neutered with shortcuts, that doesn't even show the growth of Ender to become the commander - and the side story arcs (especially Peter and Valentine's transformation to Locke and Demosthenes) are almost completely absent. Ender's Game is the type of story that deserves to have the Hobbit treatment - the story needs to be told holistically using all the source material. As a 2 hour popcorn movie; it works - as a visual transcription of an amazing fictional universe; it doesn't.

Movie: The Hobbit: The Desolation of Smaug

Peter Jackson's epic retelling of JRR Tolkien's children's story continue - with even more inspiration from other sources in the Middle-Earth universe, to tie the Hobbit closer to the Lord of the Rings. Now, Gandalf's frequent periods away from the troupe of dwarves and their hobbit burglar is explained by his side trips to investigate the rise of Sauron. 

IMO, most of the embellishments are welcome - the universe is rich and detailed, and the overall story itself is richer and more compelling through the embellishments (most of which are from actual source material). However, some are just overly distracting - Azog's continual chase of the dwarven party and the inter-species love-triangle - being the main ones for me. 

The other main  gripe for me - is the sudden, inexplicable changes in geography - almost like a Bollywood song & dance routine. One minute they are on a mountain top being chased by wargs, next minute they are running through a field of flowers; still chased by wargs. 

The approach taken in the Hobbit does raise an interesting question - should the entire Middle-Earth universe not be better served with a wider, chronologically perfect, movie/TV series. Tolkien's world is rich with tales, and an epic series would put Game of Thrones to shame. Yes, Smaug in the massive cave with golden treasure is amazing on the big screen - but even a small screen rendition of the entire universe would be worthwhile.

Ender Series

I first read about Orson Scott Card's Ender's Game, when commentary about the movie started appearing on the web. Intrigued, I read the first chapter at Exclusives, and then got hooked - so got the full series. 

While it is sometimes a straight forward science-fiction novel, what I really like about the series, is the intersection of philosophical discussions on alien interactions - something that is not only applicable with regards to interactions with other sentient species (whose numbers are now far more probable) but also species that seem to be non-sentient. It effectively turns the idea of animal rights on its head - does the fact that humans don't understand communication of other animals on Earth imply that they are not sentient - but rather that we merely can't communicate with them. 

The other key idea is the concept of life itself - specifically, when should a computer program, without a physical presence be considered alive. I did not particularly like the eventual descent into metaphysics of what is the soul - but the very idea of an artificial program that could be alive and is alive in all senses but for the fact that there is no physical body; is a great construct.

It is a brilliant series, and the series had amazing foresight - given that many of the technologies such as the Internet, mobile devices, social media etc. did not exist (or existed only in a very early form) when the series was written. I especially enjoyed the second (Speaker for the Dead) and third (Xenocide) books - and the full series is well worth reading.

Movie: The Hunger Games: Catching Fire

For many trilogies, the second book is often the bridge with a lot of plot development but little in terms of action. In the Hunger Games series, the second book, Catching Fire, IMO, is the most interesting. The first book introduces the reader to a very impressive dystopian world, and the third book's plot line is rather expected. The second book is a bridge - but the brutality of the Hunger Games world is amazing in its depiction. The movie is quite true to the book's depiction, although not as much time is spent on the game itself. It is a very worthy sequel, and a worthy film translation.

Goodbye Madiba ...

The first email notification I saw this morning around 5am, on my iPad was an email from J, titled "Nelson Mandela". I didn't read the email then - I was quite sure what it would be about - and it was confirmed when I opened Flipboard - and every other newsite/app. Even Fox News has an obituary - and the only one I saw that referenced the fact that he was listed as a terrorist by the US government.

It was not an unexpected event - he was 95 years old, he was critically ill for a year - but it was a somber day nonetheless. Colleagues even mentioned how quiet and somber it was - not only in the office we were in; but also in other offices.

I don't have a Madiba story - but modern South Africa, is in itself the Madiba story. The remarkable progress made by South Africa is almost unparalleled in other parts of the world that has seen opression - or still have opression in one form or another. That is his biggest gift - and if others can emulate, his biggest legacy. 

Thank you Madiba.

Movie: The Butler

Based on a true story, The Butler recounts the very inspiring tale of a black man who flees the opressive American South in the early 1900's to eventually become the most trusted Butler in the White House. Forest Whitaker delivers an amazing performance, and is ably supported by a superb cast including Oprah Winfrey (as the alcoholic wife) - superimposing the struggles against racial inequality, the American civil rights movement, and the Butler's front row seat in the heart of the political machinations.

The problem of the movie however, as extensively documented in Wikipedia and elsewhere, is that the story is quite far removed from the truth in many details. The movie is based on a Washington Post article, and the real story, by all acounts is very much worth telling - without embellishment. The fact that so many distorting story naratives are introduced; the actual power of the true story is somewhat lost. It does not take away from an excellent movie - but it does tarnish the real story's power.

Suitcase

Guitar duo CH2 and cellists from "The Paz Consort", combined to give a great concert melding classical and contemporary music together. It was really a dark, stormy night - maybe a factor in a half full venue at University of Johannesburg's Arts Centre; and it certainly deserved a full house. The guitar work of CH2 is amazing, especially in the virtuoso pieces - but the melding of genres was very impressive. It was certainly worth braving the downpour!

Parklife Festival - Nov 2013

Planned to celebrate summer, Parklife Festival is set to be a bi-annual concert series; the first one taking place in March this year. While there was a great lineup of bands; SA super band Seether was the real attraction. The organization at Marks Park was excellent, and although the rain threatened throughout (including a few drops), it stayed away.

I had originally thought to go fr Desmond and the Tutus, but M and I went to lunch at 44 Stanley instead; but did make it for Taxi Violence. It has been a long time since I last saw them, and didn't really enjoy them today; so we didn't stay too long. So instead we headed off to the main stage to start staking our places.

One man band, with a few mates, Jeremy Loops was the act before Seether on the main stage. He is certainly a great musician, combining loops of harmonica, vocals, guitar and beat-boxing (all recorded live) - it is quite impressive to see it all come together. The lyrics are fairly simple (and not much to speak of); but he is an interesting act to see live.

There was no point to go see The Dirty Skirts; and rather we decided to et a really good place to see Seether. The Seether set was largely acoustic, and devoid of the stand and deliver approach of the previous shows. It was rather sedate in their standards (after all, in Opikopi last year, Shaun Morgan finished by smashing his guitar) - but it was more interactive, more engaging - and overall a perfect performance for a Sunday afternoon.

 

Starting the show with the Saron Gas standard - Gasoline, it was really hit after hit. There was a strange lul when they played a cover of a Neil Young song, but every Seether song was sung with gusto by the crowd.

The encore was interesting, as one of the roadies, Brian, joined in for the performance Remedy. It was another great performance by Seether and hopefully the Parklife Festival brings in more great bands in the future.

ZaCon 5

If ZACon 5 was a true representation of the security practitioners in South Africa, it would seem that there are next to no women - after all, only 1 lady in the audience of 100 plus gives a pretty skewed demographic. Perhaps this is a phenomenon more in the hacker community itself? Perhaps it is due to the fact that the event is on a Saturday? I have commented on diversity of ZACon before, and in other respects the audience was far more diversified, be it race, organisations or age - so, it seems like gender is the final frontier :) 

Organisationally, this was the best ZACon yet - better signage, better communication, up to date scheduling (even if it did run late, and the scheduling did changed a lot), AV and sound set-up etc. As Dominic commented, ZACon is growing up, and it seems to be sustainable footing - and this is a local security conference that deserves to continue. The content was also impressive, covering a variety of interests, although there was a strong "electronics" theme. 

Dimitry started off proceedings on the use of Markov chains to create more efficient password attacks. In principle, it is a great idea, but his actual demonstration and training data was did not make sense. Password complexity rules have almost ruled out the use of plain dictionary words as passwords, and thus the solution did not have the gravitas that it could have.

Jason presented the most interesting talk, on Mains Signalling. Basically, Mains Signalling is the use of signalling on the electrical grid, allowing for controlling of electrical systems. The technology is old, undocumented, and very topical with regards to the move to Demand Side Management, across the world. Through literally years of effort, and off the shelf components, Jason managed to decode some of the signal codes - including that of traffic lights, street lights and geysers. Given that there is absolutely no authentication or authorisation built into the system, anyone with the capability to send modulated signals on the electrical grid can cause havoc - and this is something that, to my knowledge, is not addressed as part of next generation grids. Yes, it is a far more local attack - but also far more economically damaging.

Jeremy ("Panda") presented an interesting investigation on the command and control servers for the Poison Ivy botnet (and two others). Through interception of communication, NMAP and tracking IP addresses and domain registration records; and managed to identify a number of additional domains and command and control servers. And amazingly, many command anc control servers are themselves vulnerable to many attacks, due to bad configuration and vulnerabilities within the Poison Ivy system. The approach will not work for all botnets, but this is certainly a good step forward in combating botnets.

Brazilian Marcos (studying at UJ) presented the most complex talk on detecting obfuscated obfuscation routines.  The use case is better detection of malware, but could also be used to attack software that uses obfuscation as a protection mechanism. Detecting and reversing good obfuscation is difficult and although the presentation is very much in initial stages; it does have good promise.

Rhodes MSc student Adam talked about his research on active honeypots. Traditional security technologies, like firewalls and anti-virus systems have high cost in detection, but low cost in carrying out enforcement. Conversely, honeypots have low cost in detection, but high cost in actually carrying out meaningful actions. The presentation was therefore on building a converged system - low cost of detection, and low cost of enforcement. In some respects it is a better IPS - and the approach is interesting; though probably not completely scalable. 

Dave from MWR's UK office gave the scariest talk of the day - on how it is easy to hijack ad networks to infiltrate ad-supported apps on mobile devices; most notably on Androids and jail broken iPhones. Ads are effectively webkit implementation within apps; but through bad design, vulnerable implementations, intentional wish to hijack data, bad sandboxing, and ads inhering permissions of the underlying apps, ad networks are effectively able to pull various types of data, or take actions such as sending messages or making calls. This means that the attacker can effectively hijack legitimate ads for their own purposes (since ad network traffic is often unencrypted) or in an easier (but potentially tractable) attack, launch an ad campaign that sets out to attack their targets. It was  truly fascinating insight into the problems with the current mobile advertising landscape and the lack of real incentives to address the problems.

Mark, also from MWR, but the SA office, gave an insightful overview of Control Area Networks (CAN), specifically in the cars. While there was some exploration on possible vulnerabilities, it was more of a discussion on reverse engineering. There are interesting avenues to pursue - especially remotely via avenues such as keyless entry or telemetry broadcasts for race cars. 

In the past year, Robert, started a conversation on building a data diode - or a one way transmitter of data. Considering the massive cost (some over 100's of thousands of Rands) of commercial systems, Robert's solution, costing less than R5000, is therefore an amazing hack; and one that works as advertised. 

The last talk was by Shcalk, on designing a low-gain directional Wi-Fi antenna; but was really mostly about 3D printing and house-4-hack. The 3D printer itself has got awards, and this is a good showcase of entrepreneurship. It was a good follow up to Roelof's (from Paterva) talk on the basic building blocks for building a successful business. It was a good way to close off a fascinating day.

Blood Brothers

David Kramer's adaptation of the Classic English musical, which has been transferred to Take place in District 6 instead of Liverpool. The story itself doesn't focus on the politics, or race, but rater differences in economic backgrounds. 

It's a story of a struggling mother who gives up one of her new born twins to her well off employer. The boys discover each other, become friends, grow up, but remain unaware of their relationship. Eventually the story ends in tragedy, and the story is very much focused on te guilt trip of both mothers, as the narrator keeps reminding the audience, "the tokoloshe has your number".

The performances are amazing. The brothers, played by Eprahim Landrew and Dean Balie, give very believable performances across different ages, from 7 to 25. The standout performance is by Bianca Le Grange, as Mrs Johnstone (the biological mother), and although M doesn't agree, I also enjoyed the narator's performance in bringing the story together.

It is a brilliant performance all round, and David Kramer's adaptation to South African cultural references is amazing. It is show definitely worth watching. 

JPO's 2nd 2013 Season, 6th Concert

Given the difficult year for the JPO, the final concert of the year started with a few words of thanks - both from the CEO of the JPO and the concertmaster. I think that the JPO needs to do a lot more to overcome its challenges, but that is a post on its own. The concert itself, for me, was a bit underwhelming.

Schumann's Manfred Overture started the proceedings off. Unlike the programme notes, I did not think that the piece conveyed "effectively the urgent despair of Byron's work" - not that I know the poem that the piece is based on. While it certainly had a melancholic ending - there are certainly other pieces that I have heard that evoked sadness than this piece. 

Violinist Yura Lee performed Mendelssohn's Violin Concerto; a very popular piece that I have heard on radio numerous times, in pieces, but not as a full work. Unlike some concertos, it does not seem to require significant individual brilliance; but it is a great piece to listen to; and got great appreciation from the audience.

Brahms' Symphony No 2. ended off the evening. It was certainly a nice piece to listen to, but I found that it was hardly memorable. There was no specific piece that got stuck in my mind, and I don't think I would recognise it if it was played. It was nice; but not great.

The Pudding Shop

The Pudding Shop, in Parktown North, aspires to be a vegan friendly restaurant. That means, the menu is largely vegetarian or vegan (although it is not that easy to see which is which) but also has a few fish items for those that must have some animal protien. The food is delicious, the decor is interesting and it is a great lunch venue; especially on a lazy weekend. And best of all, it doesn't have the preachy holier-than-thou attitude of other vegan/vegetarian places I have been to (outside Asia).

That said the service is quite poor. The waiters didn't really know the menu; and for a vegan/vegetarian venue, their selection of food and drink is actually quite limited. It is not that the waiters are unfriendly - in fact they are very hospitable - but their lack of knowledge of the food being served does not help; especially when the menu is mixed.

Wooden Buldozer

The Rosebank rooftop market restarted last week, and this time it feels a lot more spacious with somewhat better quality. A Malawian stall had hand carved wooden toys; and the bulldozer really stood out. All the parts are movable, including the arms and the tracks. Really impressive craftsmanship!

JPO's 2nd 2013 Season, 5th Concert

Sibelius' 2^nd Symphony is awesome, not only the finale, which is very rousing (and as per the commentary, seen as the unofficial Finnish national anthem) and loud; but also the second movement, which has a very interesting start with the double-basses and cellos; and everything else just seems to fit together. No doubt, part of the success of the performance was due to the conductor Yasuo Shinozaki's experience with Finnish music; and it was one of those magical performances where the music just seems to come alive.

Unfortunately, the first part of the concert was more mundane. The first part of the concert was rather short, lasting just over 30 minutes. Proceedings started with Mozart's La clemenza di Tito Overture, followed by Tchaikovsky's Variations on a Rococo Theme played by Russian born, South African cellist Polina Burdukova. Neither performances were bad - just boring. The symphony did make up for it though!

Macbeth

It's quite cool how some traditional artistic companies are leveraging new technologies to reach new audiences - the Metropolitan Opera and the UK's National Theatre being at the forefront. It opens up their productions to new audiences; and gives different avenues for movie theatres at the same time.

Ster-Kinekor is currently screening National Theatre's production of Macbeth starring Kenneth Branagh. Performed in a deconsecrated church (how is a church deconsecrated?), the "stage" is in the centre of the church, with the audience sitting on either side. The action is fast paced, with no time taken for scene changes; and there is a very earthy; middle-age feeling about the play - particularly in the beginning with the water effects (for rain) that turns the stage into a muddy field. 

It is minimalist; at the same time quite impressive in the use of effects. The performances are brilliant, not only by Kenneth Branagh but also by Ray Fearon as Macduff and Alex  Kingston as Lady Macbeth. 

I saw Macbeth in school, as part of the set work - this is the type of production that makes Shakespeare amazing, even when it is not part of schoolwork :)

Meze, Mira and Makeup

A play with only one cast member can be difficult to pull off; and Taryn Papadopolous Louch did an absolutely amazing job in portraying a wide range of characters in the life of Kalomira (Mira) from birth, through to end of her University degree. Although very much rooted in the immigrant Greek experience, I don't think the experience itself is specific to Greek culture - but rather a wider take on immigrant life in the new home; and the difference in experience between the 1^st and 2^nd generation immigrants.

The acting is absolutely amazing - especially in how well the characters are portrayed; and the play is hilarious. The accents and the exaggerated character effects are well portrayed and the performance got a well deserved standing ovation.

Soil

The Auto and General Theatre on the Square is hosting a month of Greek flavoured SA plays. The playwright of the first (Soil) and the director of the second (Meze, Mira and Makeup), Renos, is part of M's writing group; so we got an invitation to the opening day. It was my first time at the theatre, and being effectively next to the parking lot, has its disadvantages - mainly in hearing car doors slamming and alarms going off. That said, the acoustics are pretty good - so you don't struggle to hear the actors on stage.

The first play of the evening, Soil is based on a true story of a South African of Greek-Cypriot descent's return to the house of his grandparents, and meeting the Turkish-Cypriot lady living in the house - a house given to her father by the occupying forces of Turkey. Effectively it is a story about land rights - and although not directly explored - the history of Cyprus (as encapsulated on Wikipedia) it is a long running saga of multiple occupations and settlements.

The play's structure of three parts, makes it a bit difficult in terms of pacing - dragging on the topic a bit. This is particularly notable in the very end - a part that I thought was completely unnecessary; as the conclusion in the story had already been reached. 

It is a topical, and partly political play. However, it doesn't really have a take on the actual answer - the encounter is so specific; it does not really highlight any meaningful solution to the wider problem. It was still good theatre.

Halloween - JPO's 2nd 2013 Season, 4th Concert

I love live music because of the experience - be it the audience, the unique performance or just the sound. Last night's JPO concert had all of these, and was one of the best.

It started with the performance of Musorgsky's Night on Bald Mountain, a piece that has all the hallmarks of horror genre. The lights were switched off, lights flashed for lightning, and as dawn broke through lights grew brighter, gradually. It was a totally immersive experience that is needed more often.

Tchaikovsky's long 2^nd Piano Concerto was next, featuring Francois du Toit as the pianist. It was a mesmerizing performance, with a lot of highlights even though the piece itself was not particularly memorable. It had some sorrowful moments, but did not really continue the theme.

Saint-Saens' 3^rd Symphony featuring an organ and a piano rounded off the evening. The organ's notes had an amazing vibration even though it was not a full blown organ that one would find in a cathedral. 

It was a great evening, and I hope JPO can repeat similar experiences more often.

Movie: Blue is the Warmest Colour (Adele Part 1 and 2)

I bought tickets more on the reputation than anything else really - and it was a very last minute decision. It was being screened as part of the annual "Out in Africa" festival, so it was a special screening before a wider South Africa release.

It is a simple movie premise - following the life of a young woman (starting in High School), Adele, through to her late 20's; through the cycle of one serious relationship, with an older woman, Emma. From the incidental meeting at a traffic light, through to "living house", through to a rather impressively acted dissolution, and a few years after; the movie has amazing atmosphere.  The movie uses quite a few clever ways in representing time (through the course of 10 plus years); but sadly the visual appearances of the two main characters remain the same and in some respects there is actually little change in how the characters act and behave in this time period.

The major talking point (and associated controversy) is the very long, quite explicit first sex scene between the two characters. While it starts of as erotic, and manages to convey a lot of passion, it carries on for too long - so much so, that an audience of predominantly lesbian women, starts laughing. It becomes tedious, and together with a number of other long lingering scenes, it contributes to the overall slow paced, tediousness of the movie brought on by its length. 

Overall, it is a good movie, with some good acting, and a good script - but too long. I am happy that I went to watch it; but I wouldn't want to again.

Johannesburg International Motor Show

I have been mulling over on whether to buy a new car, but my current one if working fine, so there is no motivation to really buy a new one (other than having a new car). That said, the Johannesburg International Motor Show was a good opportunity to see what is coming out in the recent future; and I was specifically interested in the electric cars that may be coming to SA soon.

Of the cars, the most imminent is the Nissan Leaf, which is launching next month. But it is not a car that looks like it is worth just under half a million Rands. In looks to other similar priced cars - 3 Series BMW, Audi A4, C-Class Mercedes - and this just doesn't stack up. It does have all the gadgets; it is fairly comfortable and quite nice to drive (I took the short test drive on offer); and the promise of incredibly low fuel costs does provide some of the positives. It has a 24 KWh battery, and a range of approximately 195 KM. Based on current SA electricity price of approx R1 per KWh, this translates to an incredible 12c per KM of fuel costs - far less than any petrol/diesel equivalent. But with a general lack of charging stations (right now at least) and the high investment cost; it may be better off to get a highly economical diesel.

Mahindra was the other "low cost" vehicle manufacturer with an electric car on show - which looked a bit like a bulkier golf car to be honest. Interestingly none of the other Asian manufacturers had hybrids or electric cars on show; except for existing offers from Toyota (and Lexus) and Honda.

The feature car that all the papers were talking about was the BMW i8 due to land in SA end of next year/early 2015. It is a great looking car, but there wasn't much on performance or price (although the agent did comment that it was going to be at the R2 million mark). The BMW i3 is also expected to be launched next year, but at the reported price of R1 million, it is worth two Nissan Leafs, and looks worse!

The i8 was not the only hybrid/electric stunner on the floor. Honda's new NSX is absolutely beautiful, though no other details were available, and is still in a concept phase I think.

There were a few interesting, non electric cars to see also - Chevrolet's Camaro is a classic American Muscle Car, but no further details were available. Giniel de Villier's Dakar Rally Car, a Red Bull F1 car and the Lexus LFA (which Top Gear called best car in the world).

JPO's 2nd 2013 Season, 3rd Concert

The program notes that Japanese conductor Yasuo Shinozaki spent considerable time leading orchestras in Finland. It was therefore apt that his 3 week tenure as the conductor of the JPO started with Jean Sibelius' Finlandia, performed with great gusto. It is a great piece, especially performed live.

Violinist Matthew Trusler performed Benjamin Britten's Violin Concerto, which was a stark contrast to Finlandia's exuberance. Written during World War 2, it is a melancholic piece (although I am not clear on whether it is mourning the event of a war, or the outcomes of the war); and although there are clearly passages which require great skill to perform (especially in the second movement), it was not a very enjoyable piece in itself. It was amazing to see it being performed - but I am not sure I would like to hear it again.

Rachmaninoff's Symphony No 1 rounded up the evening, which was yet again very boisterous. I really enjoyed the piece, especially the various contrast between the strings and the brass and percussion elements. It was loud, it was interesting, it was happy - almost all the things that the violin concerto was not - and I thoroughly enjoyed it.

Movie: Gravity

There are movies that are cinematic masterpieces, and then there is Gravity which sets up an even higher bar to achieve. It doesn't matter that the visuals of the movie were mostly computer generated - it is an amazingly beautiful spectacle. The science may not be perfect and the plot could have focused less on moving from one disaster to another (I was wondering, almost hoping that a great white shark would appear). 

The great acting performances (especially by Sandra Bullock as the survivor in empty space), the masterful depiction of weightlessness and the amazing cinematography are pull together to make an amazing movie.

Side Channel Attacks in the Cloud

I saw this paper (by Yinqian Zhang, Ari Juels, Michael K. Reiter and Thomas Ristenpart in ACM CCS 2012) earlier this year, but thought it was a very specific threat model. In a  one line summary - it is possible to recover private keys when they are being used within a virtual machine, through observations of the activity of the virtual machine from the host machine. It is a very complex attack, and requires at least host access for these observations, so my initial thoughts were that this attack could only be carried out by extremely skilled admins of a cloud hosting provider; but the complexity would probably mean that there was no realistic threat in that regard.

With the NSA revelations of the past few months, this is an interesting approach that could be taken by an agency (such as the NSA) to recover private keys from cloud providers, without getting actual access to the servers themselves. Given that PRISM does provide such access to hosts, it is not inconcievable that systems that are hosted on public cloud services such as Amazon's EC2 could be monitored. However, given the description of events relating to Lavabit, it is likely that this type of attack hasn't been operationalised yet - but remains interesting on what could be achieved.

1820 Settlers National Monument

The 1820 Settlers National Monument is just outside Grahamstown, offering fantastic views of the town. A monument celebrating English settlers, it is in many ways a monument to colonialism - especially with cannons pointed towards the town; although the monument website talks about anything but that. The foundation building itself was closed on Sunday, but the views were worth the stop.

Grahamstown

This is my 3rd time in Grahamstown, though the first extended stay here. It's a small town with impressive colonial architecture (at least in the central part). The weather hasn't been great (quite chilly actually) it's a nice plae to visit regardless.

JPO's 2nd 2013 Season, 2nd Concert

Pianist Jan Hugo was completely focused on the keyboard as his fingers sped across the keys. He looked at the conductor for his cue, swayed slightly when it was just the orchestra; but mostly he was focused on the piano keys. It was a mesmerizing performance of Mendelson's 1^st Piano Concerto, which got a rousing applause from the audience; so muh so, that the pianist obliged with two encores.

Before the concerto, the JPO played Mozart's Magic Flute Overture; and finished off with one of the most well known symphonies - Beethoven's 5^th. Once again, conductor Daniel Boico brought great energy to the performance - especially for the symphony.

Yet another great concert from the JPO, and a great selection of pieces this week.

Movie: RED 2

I enjoyed RED, and the sequel is much more of the same. As in previous movie, ex-CIA black OPS, Frank Moses (Bruce Willis) and his best friend Marvin (John Malkovich) are being chased by a number of governments relating to an old operation known as Nightshade. Set up across 4 countries, there are brilliant performances by Anthony Hopkins as the deranged villain and Helen Miren gets to play the queen again - although this time it's in a psychiatric ward. 

Despite some amazing stunts, the movie felt less slick than the original. The plot has a lot of holes, the dialogue seems to have been written by different writers (of different abilities) and the story sometimes looses steam. It is still funny, and a very good antidote to the run of the mill action story.

JPO's 2nd 2013 Season 1st Concert

There was a noticeable influx of youth (well anyone under 50 would be young right?) at yesterday's JPO concert - in the audience, in the orchestra, which was also led by the relatively young conductor Daniel Boico. Daniel Boico brought some amazing energy to the orchestra - especially in the opening piece; Rossini's William Tell Overture. I have heard this piece performed before, but this JPO performance was something special.

Luis Magalhaes played Rachmaninov's Piano Concerto No. 4 next, which was sadly not at the same level. It was a strange piece - and it just didn't have the wow of Rachmaninov's earlier concertos. 

The evening ended with  Dvořák's Symphonny No 8. While it is not as recognisable as his 9th, it was a good mixture of emotional mood and was once again energetically conducted and performed. 

For an orchestra that flirted with its demise due to funding problems, this was the exact statement of revival that was needed. It's a pity that the hall wasn't sold out ...

Sport Development and Diversity

Business Day has a great article exploring why black rugby players who seem to succeed on the field in junior rugby do not succeed as they go up the age brackets.

It is an argument I have made before, in my experience with badminton in Cape Town. Sports development is not only about training and coaches - it is about nutrition, about emotional support, about family support, and a whole lot else. If kids are going to spend hours to get to training, development is not sustainable. If kids are not going to get good nutrition at home, they will physically not develop regardless of the hours they spend in gym as part of their training. If they do not get support in their education and family life (which may be in non traditional family structures) they will have other things to worry about.

That said, I am not sure that boarding school, as advocated, is the solution. In my own experience in Cape Town, the fact that top players (including national players) stayed an played in the community was in itself a promoter of the sport. Ultimately, I think a balance is required and it required support from multiple spheres of government and civil society.

Trevor Noah: It's My Culture

I bought my tickets to the show in August, and already most of the tickets had been sold out for the 3 week show. Trevor Noah has had a fairly meteoric rise as a comedian - I first saw him as a support act at a comedy club about 5 years ago, and now he has 2 hour shows across the world. 

The content of his act varied widely, and he is a great story teller (and writer); managing to get laughs from even difficult topics. The story about his meeting with Julius Malema was particularly impressive, as was the brilliant story of the arrival of the escalator in Zambia (which is not too say that Zambia is technologically backward). 

Earlier, the show opened with a drummer and a puppeteer with 2 dancing puppets (who put Miley's twerking to shame). It was followed by short act by Dusty Rich; which comprised of commentary on his name and blaming his parents for (in his opinion) various genetic defects. The puppeteer was amazing; Dusty was just ok.

I am not sure that the show itself lived up to its name; but that doesn't really matter. It was a great show that definitely lived up to Trevor Noah's well earned reputation.

The Price of Prepaid Mobile Data

The Economist has an analysis of mobile data prices (prepaid), with some surprising results. When the average prices are measured against the country's average income levels, SA prices do not come across as too bad - especially when compared to the US prices; and most of BRICS seem to be on par. With the recent announcement of even further cuts to mobile prices due to reduction in termination rates, the mobile data price should get better!

And Then Steve Said, ‘Let There Be an iPhone’

The NYTimes has a great article on the design and engineering challenges of building the iPhone, particularly leading up to its unveiling. It's particularly interesting how rough the initial demo units were, and how much improvement was actually done in the 6 months before the actual public availability. But best of all, it is a fantastic discussion on what it takes to deliver a brand new product; and the bets that Apple effectively took to deliver the iPhone (effectively stopping development of all other products to focus on the iPhone). 

There are a lot of articles on Steve Jobs today, and this is probably the best of the lot.
