Misunderstood Math and Big Data

March 21, 2015 by kostadis roussos Leave a Comment

Over the last year, I’ve met a number of autodidacts in the big data space. They take some big data database, grab some statistical method they poorly understand and create chaos.

The problem is that an army of systems engineers have made it possible for people who don’t understand statistical methods or machine learning to use tools they are woefully unqualified to use.

My wife called me up yesterday to tell me this joke about physicists and mathematicians.

Thing is I had heard this joke many, many, many years ago that I found amusing but not super funny. And yet when she told me to think about all of those big data projects, I died laughing. When she got to the punch line, I was laughing so hard I couldn’t breathe.

MoneyBalling Recruiting Engineers or looking for Usain Bolt

March 15, 2015 by kostadis roussos Leave a Comment

Usain Bolt is possibly a fascinating athlete in sports. His body is just wrong for running sprints. He’s too tall.

2015-03-15_1413

And yet some coach decided to overlook his body type, and records fell by the way-side. So much so that I have to believe that coaches worldwide are now looking for tall, not short, sprinters.

I recently saw this post float by Twitter on secretly terrible engineers. The general thrust of the article was that perhaps the interview process was profoundly broken in some way.

And then there was this exciting follow-up on grey beards and the use of questions that only a college grad would be familiar with as a way not to hire grey beards and approach to find out who is ‘old’ without asking their age…

And I thought about money ball. In money ball, Billy Beane questions how we select people to make up baseball teams and radically transform the sport of baseball opening it up to players that we would never have considered in the past.

The current recruiting system is running up against a brick wall of supply. At this point, we don’t have enough people graduating with advanced degrees in CS. As Kate Heddleston puts it so well, we are running out of people who can do the 100m dash who fit the 100m dash profile.

I believe that there will be a strategic advantage for the first tech company to figure out how to hire people who do not fit the 100m dash profile. That company will recruit more people more efficiently and get more out of them than any other company. Unlike outsourcing, which companies did to drive costs down and therefore easy to replicate, I genuinely believe that this will be disruptive in a way that we can’t imagine. Hiring, promoting, rewarding, and training people will be different. I wish I could tell you what it was, but as a beneficiary of the current system, I don’t know and can’t imagine. I know it will be different.

My only hope is that I will be able to adapt and not be like those short guys watching this tall dude blow past me…

Bubble bubble toil and trouble

February 27, 2015 by kostadis roussos Leave a Comment

Earlier I wrote about early stage valuations being de-risked through schemes similar to how mortgage backed securities were derisked and how that was creating a bubble. The reason derisking creates a bubble is that  by artificially de-risking a high-risk investment, the amount of money that can be invested increases significantly.

To speak in math: if the total amount of money to invest is MONEY, and only 10% of MONEY can be invested in high risk investments, then only 0.1*MONEY is available to invest. Now suppose I can take an investment vehicle, like an early stage start-up, and de-risk the investment, then instead of only 10% of MONEY being available to invest, 30% or 40% of MONEY is available to invest. The net effect is to increase the total amount of money entering the market creating an asset bubble.

If the total amount of MONEY is also increasing (thank you QE), then you have two accelerators – the derisking making more money available and more money coming online…

As for how to derisk an investment … 

There are two ways to derisk an investment. The first it create a hedge. The second is to foist more risk on some people and less risk on others. So for example, in the mortgage backed securities market we had both. We had credit default swaps as a hedge, and senior debt as a way to derisk the investment for some. In the early start-up game, the hedge is to invest in many different start-ups in the same space, and the derisk strategy is to have warrants on any early liquidity the company may get.

Essentially the investor is pushing more risk on the employees and founders by being first in line to any money the company makes.

But there is another way to derisk … 

The other way to derisk is to believe that something is less risky. Essentially we take leave of our senses, and believe the hype that surrounds us. This second form of derisking is far more dangerous and far more explosive.

After I wrote my little note, this made the rounds: https://www.linkedin.com/pulse/investors-beware-todays-100m-late-stage-private-rounds-bill-gurley where he seems to be arguing that traditional risk analysis is being ignored in favor of a devil-may-care must-invest-at-all-mentality…

And it all leads to this: 

The author, Bill Gurley,  had this money quote:

All of this suggests that we are not in a valuation bubble, as the mainstream media seems to think. We are in a risk bubble. Companies are taking on huge burn rates to justify spending the capital they are raising in these enormous financings, putting their long-term viability in jeopardy. Late-stage investors, desperately afraid of missing out on acquiring shareholding positions in possible “unicorn” companies, have essentially abandoned their traditional risk analysis. Traditional early-stage investors, institutional public investors, and anyone with extra millions are rushing in to the high-stakes, late-stage game.

With the downside for the investors being derisked either through hedges or warrants, and the risk of poor outcome being pushed on the employees and founders, the companies are actually being forced to take bigger risks and by taking bigger risks …

But why?

Remember what I said earlier, with warrants when a company has a liquidity event the early investors make most of the money. Consider a hypothetical company that has it’s paper set up in such a way that any liquidity event up-to 500 million dollars the employees get to split less than 50 million dollars. The employees and CEO are now motivated to go after a billion dollar outcome.

And So?

The problem is that it’s a lot easier to hit 500 million dollar exits (historically speaking) than 1 billion dollars.

So the CEO decides to go for it because only if he goes for it does he make any real money thus he increases the risk

The problem is by going for it – he actually is increasing the risk of complete loss.

So ironically by derisking the investment the overall risk is actually increasing.

Somewhere Nassim Nicholas Taleb is smiling

How no-risk is creating fake unicorns in the valley

February 24, 2015 by kostadis roussos Leave a Comment

Thoughts about bubbles and unicorns in the valley.

A bubble emerges when folks make investments that are risk free and have high yield. The appetite for mortgage backed securities was tied to the need for yield and the way in which the underlying asset was assumed to work. Basically the idea was that there was an upside risk but no real downside risk especially for the owners of the senior debt. And so people bought the asset figuring that in the worst case they made no money.

One of the interesting phenomenons in the current  in funding bubble is the assumption that because of the scale of companies there is no risk to the investment. There may be marginal upside but the downside risk is marginal.

For example, one view of the SnapChat investment is that in the worst case the company is worth a couple of billion dollars. If you can structure your investment in such a way that you get your cash preferentially when the company gets sold, then as long as you get your millions your okay.

Because I don’t actually understand the details of the SnapChat investment, let’s talk about company X.

Suppose you invest 10 million in company X at 2 billion dollar valuation. Your upside only exists if the company is worth more than 2 billion – unlikely but still plausible. Your downside, on the other hand, may be significantly less risky. If you believe the company will get sold in the worst case for 10 million dollars and that you are first in line for the 10 million dollars, then this is a risk free investment. You simply can not lose your money so why not take the risk?

The beauty of this arrangement is that it works great for everyone. The founders get the cash they need without having to dilute their equity in the company. Presumably 10 million at 2 billion valuation means a lot less stock dilution than 10 million at 20 million valuation. The VC’s get to show growth in their portfolios – especially if they made an initial investment at 100 million. Just to make that point a little bit clearer – they invest 1 million at 10 million valuation, then 9 at 2 billion and their initial 1 million investment appears as a paper profit of 20 million dollars.  And the employees get to feel that they are in a  rocket ship that is going to outer space. And the LP’s in the fund get to see growth with no risk.

The downside, of course, is that the risk free nature of this investment may be a mirage. For example, the company may not get acquired for 10 million dollars, it might become vaporized. Or worse.

When everyone believes in the downside risk thesis we have bubbles. If everyone believes there is no risk and there is a lot of cash around – thank you QE – then we have a bubble because you become stupid to not invest in risk free investments with high potential yield.

Since I am fan of the black swan books, my belief is that when too many people believe in no risk, then risk gets magnified and disaster emerges.

We’re not there yet, we are in a boom – the danger is the boom turns to bubble before it becomes a bust.

Here Comes Another Bubble: More data

February 15, 2015 by kostadis roussos Leave a Comment

When you look at the startling increase in dollars being pumped into seed start ups as compared to the rest of the bay area economy, you know we have a bubble.

And then there is this data shared by Thomasz Tunguz.

Start up office space has grown 12% CAGR and Start up salaries have increased 15% CAGR over the last five years. Just to make this real for those of us who still earn the bulk of our money from our salaries, in 2009 a start up was paying 90k a year and in 2014 a startup would be paying north of 170k.

If these increases were driven by customers buying products, this would be a good thing. Except it’s not. These increases are driven by an increase in funding levels. Essentially more VC’s are being given more money to put more money into more start ups.

Given that these price increases are sustained by increased funding levels not increased revenue levels, this will end in tears.

The funding spigot will end at some point in time. And when it does we will have three corrections

  1. A sudden and dramatic collapse in employment as start ups get vaporized.
  2. A sudden and dramatic collapse in salaries as more people chase suddenly fewer jobs. The jobs they had will disappear and the new companies that start up will hire at rates that are more like 2009
  3. A sudden and dramatic collapse in office real-estate

The only good news is that traffic will get better for folks who are able to stick around…

The end of Silicon Valley, Long Live Entrepreneur Valley

January 26, 2015 by kostadis roussos Leave a Comment

There is this discussion going around VC circles about full stack startups. The notion that the business doesn’t just build a gadget but a complete end-to-end business. This a profoundly different kind of business investment for the valley and worth mulling over…

Over the last fourty or so years, Silicon Valley has been about making technology investments. Companies were created to build things that other businesses turned into products that real people consumed.

Put differently, technology was created to be in the service of a business like Starbucks. Silicon Valley built the technology that enabled Starbucks to sell more coffee, better treats and yet Starbucks is just another entrant in the restaurant business. Essentially companies outsourced their IT engineering budgets to high tech Silicon Valley companies.

The emergance of companies like uber and airbnb and altschool and Luxe and of course Amazon are not about technology companies but instead companies that happen to leverage technology. These companies may have a tech budget but their business, their products and the bulk of their staff are not technology. They use technology, they may invent technology but engineering exists to serve. Engineering is a service inside of the business not the business…

Sure tech is important to uber but the drivers are vastly more important…

These are just normal businesses that happen to get funded by VC’s… They are not traditional high tech companies…

As more of these companies get founded and succeed the valley becomes more about a place where entrepreneurs set up shop and less a place where technology gets built. As investors look to find the next business to fund instead of the next piece of innovative technology there is a real risk to the original valley ecosystem… No longer are technologists the winners but conventional business men…

Over time if this pattern holds these business men will succeed and become investors who will look to create more businesses that happen to use tech or… not.

After all our current business heroes are not guys who built technology but guys who understood a business need and found some tech guys to build it. Heck when Twitter paid 10 million for A VP of engineering the discussion on business insider . com was about how overpaid he was. I mean seriously no engineering leader should be that much – because they are just a service to the business after all….

The demographic and the core of what is the valley will change and the path to success will change.

We engineers that created a small corner of the world where geeky engineering could rules will find ourselves displaced by a new very different kind of world.

Engineers may become relegated once more to being shoved in the back room while the real power within companies has meetings…

Then the question remains what does this portend for future tech investments? My gut tells me that we will see a movement of investment outside of the valley over time. As this becomes home to large conventional businesses and investors pursue more of them… The guys who want to build tech will move elsewhere because their ability to find people and get investment will be better elsewhere. The valley relied on engineers investing in each other…

My wife says change is what you can rely on. And this change feels real andd it does mean that the future will look very different….

Still remaining bullish for the valley, I am just no longer certain the term Silicon will be appropriate… Maybe entrepreneur valley…

Toddler Meets Cloud, world ends

January 26, 2015 by kostadis roussos Leave a Comment

My son and I visited my friend Jason’s house and while he was there Jason’s wife offered to let the kids watch a children’s movie. Jason, an early cord cutter, fired up Netflix and quickly had them watching a Curious George movie.

Half-way into the movie, as I had forewarned Nicholas, we headed out. Nicholas was appalled. He was convinced that he would never see how this movie ended. I had to promise him, repeatedly, that he would get to see the movie. Nicholas was dubious.

We arrived home, and mommy told Nicholas that the movie was in The Cloud and we would watch it later. Nicholas turned to mommy and asked:

Are we going to see the movie through the window or outside on the clouds?

We both started to laugh hard. And cursed the fact that we had not recorded this for posterity.

Daddy who works on cloud infrastructures, with  Mommy’s help – oh okay Mommy is much better at explaining and she did most of the explaining … , explained what cloud was.

Here’s what Nicholas understood:

Inside Onedrive

January 21, 2015 by kostadis roussos Leave a Comment

Ever since Microsoft gave away storage for a product I would buy anyways, I have been working to move ~1TB of storage to the cloud and have encountered many of the limitations of the service and learned a little bit of the technical underpinnings.

I suspect when the folks who created OneDrive imagined the service they thought pictures. And pictures have a reasonable size (1-2MB) and a small number of them. They did not imagine using one-drive to backup entire multi-100GB file systems.

And that impedance mismatch has been tough.

OneDrive uploads a small number of files at at time (2-4). OneDrive scans the entire FileSystem to find new files.

All of this will get fixed over time, I am sure although things are now kind of rough.

One of the more interesting things is that I have gotten some insight into how OneDrive is built.

OneDrive has four core elements

  1. Skydrive.exe that is the sync engine that actually copies the data to the cloud
  2. WSearch the search engine for windows doubles as a way for onedrive to keep track of the files on the file system.
  3. The use-of-stubs to manage offline files and provide the illusion of a single file system. Possibly the only good use of hierarchical storage management in the history of the snake oil known as HSM.
  4. A pretty UI

All of these technologies have been around for many many years and OneDrive is really a repackaging of all of them.

OneDrive, as a product, has the property of something that was cobbled together over time without any of the architectural integrity of competing products like DropBox or Google drive. This probably reflects the ambivalence Microsoft had towards cloud services. I am encouraged to read for Windows 10 Microsoft is working to improve Onedrive significantly.

One of the challenges for a company like Microsoft is that building a product that has the feature set of DropBox is easy, but building a competing product is a completely different can of worms. A competing product requires a deeper level of engineering than the cobbling of re-purposed technologies that the current Onedrive product is.

Microsoft’s decision to embrace DropBox may reflect that reality.

The unusable Twitter client

January 17, 2015 by kostadis roussos Leave a Comment

Been using Twitter for more than 5 years.

Have two sets of friends:
hockey and tech

Hockey folks don’t give a damn about tech
Tech folks don’t give a damn about hockey

Hockey folks don’t want to read about storage
Tech folks don’t want to read about the Habs

So I have two Twitter accounts

Really hated how there was no *easy* way to switch between them. I tweet less because of this. I read fewer tweets because of this.

Except there is … Can you tell me where?

IMG_0267-0.PNG

Not there, stop looking.

What about here:

IMG_0268.PNG

Can’t find it? Let me help:

IMG_0269.JPG

I only discovered this when my finger accidentally hit that icon. Apparently mystery meat UI is in vogue …

This time it is going to be different, NOT!

January 16, 2015 by kostadis roussos Leave a Comment

Signs of the upcoming apocalypse are everywhere… and today my wife had the latest sign.

While getting gas, my wife happened to bump into the gasoline attendant who was looking at the market on his cell phone.

And he turns to her and says: Why is the market going down these days?

Wife: How long have you been here in the valley?

Him: 30 years

Wife: Well you remember 2000? and 2008? I mean this happens bubbles grow and then they collapse

Him: No, this time it’s going to be different because of Apple and Oil and – At this point my wife stopped listening.

 

Public service announcement, it’s not going to be different. The same thing that always happens in the bay area will happen again, we are going to see an implosion of companies and employment. Like the Parable from the Gospel says: The exact time of the arrival of the bridegroom is unknown but He is coming.
