The future of Virtual Reality

This week I have started using my virtual reality headset and I have been totally blown away by it.

When you put on your headset you are transported to your virtual home, a spacious terrace on a mountaintop on a sunny day, with the birds chirping, the breeze blowing, and a beautiful mountainous landscape. In one wall of your virtual home you can manage your command center from which you can launch any VR application, and see which of your friends are online to play with. The sensation of immersion is perfect, after a few minutes you completely forget that you are not really in the virtual world, and after a few hours of VR, going back to the normal world takes a few seconds of adaptation. The realisation that you have been staring at a wall moving your arms around for hours is confusing.

Traditionally, videogames have always been limited by the screen size, the area of game was necessarily reduced to the size of the screen, hence your avatar in this world was small and so were the rest of creatures in it. This is no longer a limitation. Everything is life-size. You are transported inside the game’s world, for those of you who watched Tron, the movie, this is it. In “Star Trek Bridge Crew”  you are captain of the Aegis space ship navigating through the galaxy. When you look out the window, the immense size of the planets, meteorites and stars is breath taking. In “TheBlu” you are in the bottom of the ocean swimming with medusas, tortoises and whales. The sensation is very real and awe inspiring. In“Richie’s Plank Experience” you have to walk a plank on the top of a skyscraper and you are dared to jump off it. Even if I knew I was in the safety of my room in the real world, I could not command my feet to move. The sensation of vertigo was stronger than my brain’s logic. This is amazing!

One drawback that VR experiences have is that when your body is moving in the VR world but not in the real world, for example if you are piloting a kart, or a spaceship doing barrel rolls, your brain is not capable of understanding why your inner ear is not feeling the pressure of the centrifugal force and you get motion sickness. The sensation is similar to getting seasick. I know first hand.

Imagine working on your computer, not from a chair in the office staring at a couple small screens, but on the top of the Everest on a sunny day, in the bottom of the ocean, or in the center of the galaxy. Imagine your screen is not limited by size, but can be as large as the sky, allowing you have a 360 degree screen where you can leave your different applications. This is what Virtual Desktop does. Currently it has some limitations since the VR headset only has reading-resolution where your head is oriented, not where your eyes are looking. Google is working on a headset with human eye resolution using a trick tracking your eyes to see where you are looking at to maximise resolution in this area.

At any rate of advance in VR technologies, in the next 5-10 years it’s easy to foresee that VR graphics and sound will be indistinguishable from base reality. In this scenario, it would be possible for companies not to need to have physical offices for computer work. Workers could work remotely from their homes, teams would be distributed worldwide with a virtual office in the VR world. This office would be amazingly beautiful, spacious, sunny, with breathtaking landscapes. People would have avatars in this VR world which will allow them to have meetings, work together on projects, explain topics on a whiteboard…



How to mine Ethereum

Mining ethereum is an easy 5 step process:

  1. Get a computer with a powerful GPU or two
  2. Get an ethereum wallet here
  3. Download geth from here and run it like this in a cmd window (because if you have a powerful GPU or two you use it for gaming, hence you have a windows machine)
    1. geth.exe -rpc
  4. Download ethminer from here and run it like this in different cmd window
    1. ethminer.exe -G
    2. The -G parameter instructs ethminer to use your GPU instead of your CPU, which will be orders of magnitude faster at mining.
  5. You are set, you should see something like thisethminer

Now for the bad part. I have two GTX 1080 TI and I am getting around 62 MH/s. This means my computer is capable of taking the Ethereum block we are trying to solve, add it a random string and calculate the hash of it to see if the first ten characters are zeroes and therefore win this block. 62 million times every second. 

62 million times per second sounds like a lot! I should have good chances of winning a block once in a while. Taking into account a new block is generated every 15 seconds, I should have good chances..

The problem is that the Ethereum network has a hash rate capacity of around 60TH/s, this means that the number of hashes the network produces every second are one million times bigger than the hashes my computer produces. This gives me a chance of winning of one in one million every 15 seconds. Taking into account that the reward for winning is 5 ETH (approx 1,150 EUR), I have 1/1,000,000 chance of winning 1,150 EUR every 15 seconds if I leave my computer mining.. this does not sound too promising.

Business Intelligence state of the art

Usually when we need to understand our business’ numbers, we open Microsoft Excel and start applying filters, pivot tables and charts to try to gain insight on what story our data are telling us.

It’s 2017, Isn’t there a better way to do this?

I think it must have been around 2014 when I first heard about Tableau. I immediately liked the tool’s proposal: Easy tool to analyse data in real time without needing to be an expert in SQL, Olap cubes, or any technology. It could take as input for data any number of excel sheets, csv files, or database sources and would immediately allow the user to move the data around, establish relationships between sets of data and start visualising. I’m a visual person, I need to see things in graphical form to understand them, so I really like this concept. In the Gartner Magic Quadrant for Feb 2017, the 3 top players in the BI space by completeness of vision and capacity of execution are Tableau, Microsoft, and Qlik who offer similar solutions for front end analytics.

One of the weak points that I see in Tableau’s proposal is that it only addresses the front end, the data analysis, but leaves the back end, the data model, the origin of data, for you to deal with. In the past I’ve worked on a few data warehousing projects where the immense complexity was in creating a data model which made sense from a business perspective and which could grow with the business’ future needs. Designing the data model wrong was similar to shooting yourself in the foot, as future needs could not be adapted, changes would require refactoring of the whole data model and of the downstream systems which read from this data model and maintenance of this data model would be expensive and complex. In all cases I experienced in the past, creating a data model was similar to creating a monster which would grow in unforeseen and inelegant ways getting more rigid and patchy as time went by.

A good example of a world class level attempt at creating a data model for the capital markets world is  ISDA’s (International Swaps and Derivatives Association) FPML (Financial Products Markup Language). The data model they have birthed is immensely complex, as could not be different when the goal is to be able to map any financial instrument. Any attempt at using FPML as inspiration for your data model promises a long and complex project.

Three weeks ago, I attended Moneyconf. There I saw a company called gooddata which offers an interesting model: They take care of your Business Intelligence needs as a service. You send them your data, they organise it and offer you a Tableau style front end tool to visualise it. This would take care of all data warehousing troubles.. however I have some concerns:

  1. How do they know all the ways you need to structure your data model?
  2. Does this scale well with big volumes of data?
  3. How do they manage confidential data? Imagine I have medical records to manage…
  4. Is the front end tool as complete as Tableau?


The BI world is very cool looking. It brings promise of granting better insights and fancy looking charts, but, is the price tag worth it when we can always just grab an excel and start applying filters, pivot tables and charts to understand the story our data are telling us?


Hyperledger, IBM’s vision for a corporate DLT

In 2008, the first Distributed Ledger Technology (DLT) was created with Bitcoin. Immediately it became visible across industries that DLT technology could be very useful to transfer assets. As time passed, different implementations have come to light using the concept of the DLT which attempt to address different problems with different implementations of a similar idea.

One of these implementations is IBM’s Hyperledger. In late 2015, IBM partnered with 17 other companies:

  • Blockchain software vendors such as Digital Asset, or R3
  • Technology platform companies such as Intel, RedHat or VMWare
  • Financial services firms such as CME, DTCC, Deutsche Borse, Swift or JP Morgan
  • System integrators such as Accenture.

The Hyperledger project’s governance is chaired by Blythe Masters (Ex-JP Morgan Executive, CEO of Digital Asset) under the Linux Software foundation. This open governance allows the open source community to contribute to the project, read the source code, download it for free and use it to create new software.

The vision for Hyperledger is a tool for confidential asset transfers in an enterprise environment. These assets can be of any nature: Securities, gold, legal contracts, wills, patents, medical information… Key differences with other DLT solutions such as Ethereum, are that there is no cryptocurrency involved and that access to transaction information is restricted with access rights. Whereas in Ethereum every miner node has a copy of the whole blockchain and can access all the information of any transaction, in Hyperledger all information is encrypted, and only thanks to having the right access rights can you decrypt and access certain information. In a corporate environment this would be a mandatory requirement as you may want to give one client a 10% discount without all your clients knowing about this.

Some interesting projects going on in the corporate world using Hyperledger:

  • CLS is working on a payment netting service
  • DTCC is building a DLT based derivatives processing platform
  • Japanese Stock Exchange is testing DLT for trading environments
  • Walmart is building a platform with Hyperledger to track where a Pork chop came from in 7 minutes instead of the current 7 days
  • Digital Asset are building a tool that will leverage hyperledger to offer DLT to the financial services community.
  • Northern Trust has built a DLT for private equity

Currently there are hundreds of players in the DLT world, in my view the top 4 are R3 Corda, Ethereum, Bitcoin, and Hyperledger. It is hard to tell who will come out ahead in the end, but Hyperledger is certainly worth keeping an eye on.



Bentham, Kant, and AI-driven cars

Imagine you are driving your car at 90kmh, and you realize the brakes are not working. 20 meters ahead of you, crossing the street, are five people who will inexorably die if you run them over. Looking to your right you see one person which is sitting in a terrace eating an ice cream. Your steering wheel is working well, so you could steer your car towards the terrace killing one person, but sparing the five.

What would you do? Most people would choose to kill the one person to spare the five. Sacrificing one life in order to save five seems the right thing to do.

Now imagine you are standing on a bridge overlooking the road. Down the road comes the brakeless car, and at the end of the road are five people who are about to die run over by this car.

You feel helpless to avert this disaster, until you notice, standing next to you on the bridge, a very heavy man. You could push him off the bridge, on to the track, into the path of the car. He would die, but the five people crossing the road would be saved. To make your job even more similar to the previous example, this man is standing on top of a trapdoor which you could open by turning a car-sized steering wheel to the right.

Would you push the unsuspecting fat man? Most people would find it terribly wrong to push the man onto the track. But this raises a moral puzzle: Why does the principle that seems right in the first case – sacrifice one live to save many – seem wrong in the second?

This example, taken from a beautifully taught Harvard online free course goes to explain how the consequentialist moral reasoning of Jeremy Bentham’s utilitarianism (it is the greatest happiness of the greatest number that is the measure of right and wrong) does not hold under the scrutiny of Immanuel Kant’s Categorical moral reasoning (Act only according to that maxim whereby you can, at the same time, will that it should become a universal law).

After 11th May 1997,when IBM’s Deep Blue beat human champion Garry Kasparov, no human will ever again, beat AI at chess.

After 27th May 2017, when Google’s Alphago beat human champion Ke Jie, no human will ever again beat AI at Go.

Once AI driven cars are mainstream, no human will ever again be allowed to drive.

While a human driver has visibility of 120 degrees, an AI has 360 vision from the car, through connectivity could simultaneously have 360 vision from other neighbouring cars, from traffic cameras, or from satellites. Other AI senses could come into play which the human counterpart does not have, for example an AI car could have sonar, similar to bats echoing a signal to detect proximity. An AI could have real time knowledge of where every other car in a radius of 10 kilometres is, in what direction it’s headed, and if it has any technical issue.

Human drivers get road rage, get impatient when sitting in a traffic jam, try to stick their car’s nose in front to gain one inch if possible… all these human behaviours cause traffic jams, accidents and inefficiencies. A perfect AI driver will have none of these traits, and thanks to this, traffic jams will be greatly, if not totally, reduced.

Having a human drive in the future will be as rare as having a human clean the clothes today. I could do it, but why woud I? I have a washing machine for that.

One human problem, is what to tell the AI to do when faced with the example at the beginning of this story. Should an AI follow Jeremy Bentham’s utilitarian principles? Should it choose to kill one to save five? This is particularly dangerous if we will also want the AI to perform surgery, as in order to save 5 patients who needed a heart, a lung, a kidney, a liver, and a stomach, it could choose to kill and butcher a perfectly healthy patient which had just gone to have a regular check-up in order to get the needed organs.

In the brink of a new era, these classic, unresolved questions are more important than ever.

How can Bitcoin serve 7bn people?

Visa transfers 2,000 transactions per second, whereas Bitcoin transfers 7 transactions per second. If bitcoin wants to establish itself as a currency that can be used daily by 7bn people worldwide it needs to scale up. What can to be done for Bitcoin to scale up its transaction processing volume?

  1. Do nothing. Since the popularity of Bitcoin is growing, the demand for transactions is growing. Since there is more demand than capacity, and the miners are processing first the transactions which offer a higher transaction fee, the cost of sending money with Bitcoin is going up. Currently an average bitcoin processing fee is 101,700 Satoshis, which is worth 2.5 USD. This means that paying for a cup of coffee with Bitcoin would cost another cup of coffee in payment fees. This also means that the backlog of unprocessed transactions is growing. At the time of writing this there are 507 unconfirmed transactions. At a rate of 7 transactions per second, if no more transactions are received, it will take 2.20 hours to confirm the backlog. Imagine having to wait 2.20 hours for your coffee payment to go through.. doing nothing does not seem like a viable option.
  2. Increase the block size. By design, Bitcoin generates one block every 10 minutes. This block can fit in as many transactions as possible as long as it’s size is below 1MB. One simple solution would be to increase this 1MB limit to 20MB for example. This would fit many more transactions per block, and the speed at which transactions are processed would increase. Bitcoin Improvement Proposal BIP100 describes this. The problem with this increase is that larger blocks would make full nodes more expensive to operate, which would decrease decentralisation as some nodes would no longer be able to bear the cost. A hard fork would be needed, risking splitting bitcoin in two cryptocurrencies, and all of this would not give a final solution, as the block size would need to increase periodically to support all the world’s future transactions. Off-chain transactions would be the only long-term solution.
  3. Use each block more efficiently. In December 2015, at the Hong Kong Bitcoin Scaling event, Pieter Wuille introduced the idea of Segregated Witness, a modification to bitcoin which would reduce the amount of information needed for each block. This freed-up space could be used to introduce more transactions per block. The advantage of this approach is that it can be done with a soft fork minimising the risk of splitting bitcoin into two cryptocurrencies.
  4. Minimise the number of on-chain transactions. Joseph Poon & Thaddeus Dryja wrote in January 2016 the Lightning network whitepaper. This would enable minimising the number of transactions that need to go into the blockchain by adding a layer on top which would create one to one payment channels. These payment channels which would be fully collateralised IOUs between counterparties would form a network with which a payment could be routed. This is similar to the concept that Ripple is using, which in turn is similar to the concept of correspondent banking.

A heated debate has split the Bitcoin community for the last year. Developers, miners, markets and users could not agree on how to solve the problem, as every option had risks.

At the Consensus 2017 Conference an agreement seems to have been found. The option agreed is to implement Segwit with a 2MB block. Although even after this middle ground has been found, heated debate goes on.


Hopefully the bitcoin community will be able to find a way to find consensus, not only in the blockchain, but also in the way to evolve in order to meet the challenges that will be found.


What is a Hard Fork? Ethereum vs Ethereum Classic

On 30th April 2016, a group of developers, mostly coming from, created the first Distributed Autonomous Organisation on the Ethereum network. They called it “The DAO”.

Through an Initial Coin Offering (ICO), people could buy their DAO token. In 28 days, The DAO raised over 11 million Ether (ETH) which at the time was equivalent to $150m, making this the biggest crowdfunding in history. An ICO is a controversial way to raise money since it is unregulated and it gives buyers no ownership like equity shares would. Ownership of these DAO tokens would grant voting rights to decide what project to allocate the DAO’s capital to.

On 14th June, an attacker managed to take advantage of a bug in the way The DAO was coded and took 3.6m Ether into a child DAO, which had the same rules as the parent DAO, not allowing the attacker to retrieve the money during the first 28 days. The Ethereum foundation had 28 days to defuse this bomb. This created a big controversy in the cryptocurrencies world:

  1. The attacker argued that that money was rightfully his, since he had taken advantage of a “feature” of The DAO which allowed his action. In the smart contracts world code is law as the smart contract can be understood as a contract written in programming language.
  2. Part of the Ethereum community was in favour of letting the hacker take the money. They argued that things that happen on the blockchain should be immutable. And that modifying/censoring/corrupting the past would be a slippery slope which would open a door to do it again in the future for other reasons.
  3. The other Part of the community was against letting the hacker take the money. Their arguments were that the community could have the last word in these cases.

On 17th June Vitalik Buterin proposed a soft fork update in the Ethereum code, which would block the child DAO from allowing funds withdrawal. This would buy more time to decide what to do without the money disappearing. However, hours before its planned release, the developers detected that this would open the possibility for a denial-of-service attack. The update could not be released. The hard fork was the only way left. This hard fork would transfer all balance of the DAO to a new smart contract which would only allow the legitimate owners to withdraw. In order to decide whether to implement this hard fork or not, an online referendum was held where each Ether held gave right to one vote. The outcome of this referendum was in favour of the hard fork by 89% so the hard fork was implemented and a trigger was set in pace for it to activate when reaching block 1920000.

On 20th July, block 1920000 was reached in the Ethereum blockchain. The DAO Hack was reversed. However not all miners agreed to this and kept the previous version running, creating a new cryptocurrency called “Ethereum Classic” (ETC). Both blockchains are identical up to this block, on one, the DAO Hacker was unable to claim his prize, on the other he kept it. At the time  I had 200 ETH in my Kraken account, the day after I had 200 ETH and 200 ETC, their valuation in Euros was wildly different as the Market gave higher value to ETH than ETC.

A hard fork is a change in the blockchain protocol which is not backwards compatible. If all users agree to follow, then there is no issue, but  if some decide to stay and not accept the change, a new blockchain is created which will run in parallel and compete in the blockchain space against the original.



Homo Cyborg will substitute Homo Sapiens

In the 2012 summer Olympics, Oscar Pistorious, who had lost both his legs when he was 11 months old, competed both in the Paralympic games and in the Olympic games. He was able to run at an Olympic level thanks to his artificial limbs. He didn’t win, but he still runs faster than 99% of humans despite missing both legs.

Adrianne Haslet-Davis, a ballroom dancer, lost a leg In the 2013 Boston Marathon Bombing. Thanks to Hugh Herr and MIT’s Centre for extreme bionics, she can dance again.


Hearing aids are common as a prosthetic to help people hear, these could be enhanced to allow people to focus hearing on a distant conversation, connect them to the internet or to an alexa style AI,  or be a phone, effectively giving a holder of this prosthetic an advantage over the rest of humans.

Artificial knees or hips are common prosthetics which enhance non life-threatening issues. MIT, and Elon Musk’s Neuralink , are independently investigating how to enhance these artificial limbs to connect them to the nervous system, connecting the brain directly with machine interfaces. If this happens, this interface could become faster than our normal reflexes, potentially allowing an enhanced human to dodge a bullet.


Anthony Atala has been able to print a kidney, George Church, from Harvard Medical School is using human genome to create any organ. Sergio Canavero is scheduled to transplant a human head by end of 2017. Dmitry Itskov has set out to copy the human brain to a computer within the next 30 years.


If humanity becomes able to transfer a head to another body, then it would be reasonable to assume it could be transferred to another input/output mechanism. If memory and consciousness can be copied, then the body could be swapped for a robot which could live for long periods of time, work on our behalf, clone itself, or travel the galaxy to terraform distant planets.


These enhanced prosthetics, once they become a reality, would grant normal humans with extraordinary abilities: eyes which could zoom in, record, see holographic projections of internet data. Exoskeletons which would allow to lift heavy weights, run or jump faster. Brains directly connected to the internet, stronger bones and muscles, perfect hair…

There will come a time where being a Homo Sapiens will be a handicap. Get ready for Homo Cyborg.




Are we in base reality?

Every year, late July, I meet with my geek friends at, a computer enthusiasts party where we share our love for computers, undersleep and follow a strict diet of pizza and energy drinks.

Last year I was able to play with an HTC Vive Virtual Reality headset, and I’ve been wanting to get one ever since. The VR experience was amazingly immersive.

I played “starwars, trials on Tatoonie” and by putting my headset on I was no longer in Spain, I was in the desert of Tatoonie, I could look around me and see everything as I would expect to see in normal reality. By putting the headphones on, the immersion was complete. Not only could I see things, but I also could hear R2D2 and Han Solo speaking to me, the Millennium Falcon engines roar and the hum of my lightsaber.

Elon Musk thinks there is a “one in Billions” chance our reality is not a simulation. At the rate of advance of technology, simulations and videogames are becoming every time more realistic, from pong being two lines and a dot 40 years ago to the photorealistic games we have today.  We are clearly in a trajectory to build games that are indistinguishable from reality. Maybe it could take us 10.000 years to get there, but on a cosmic timescale this is not much time. If we accept we will at some point be able to create a simulated reality, with individuals existing within its confines, then, since mathematics will be the same, at some point the inhabitants of this sub-reality will themselves be able to create a sub-sub-reality, and so on indefinitely. Once you accept this argument has no flaw, the next logical question is: are we in a simulation? are we in base reality?

A hypervisor is a piece of software that sits between the hardware and the operating system of a computer, providing it a simulated hardware. The operating system does not know it is running within the confines of a virtual machine.

In 2006, Joanna Rutkowska presented at the Black Hat Briefings an attack named “blue pill rootkit” against the Windows Vista kernel protection mechanism. This attack moved Windows to a virtual machine, so the operating system seemed to run normally, but in reality the machine was owned by the hacker, who could run other software on the hardware outside of the virtual machine.

Rutkowska also developed “red pill”, which would allow an operating system to know whether it was running within the confines of a simulation or on real hardware.

If one of the simulated realities was able to detect whether or not it was living within a simulation, similar to “red pill”, it could communicate with the outer environment, even hack into it running arbitrary code. God could be hacked.
