ppyil··on How to sound smart on Medium
This is very similar to the famous "How to sound smart in your TEDx talk"

ppyil··on PayPal Starts Banning VPN and SmartDNS Services
I see this as a responsibility of a vendor and not PayPal. An example is an online store which only accepts payments from the UK so when I was on holiday I was unable to use that site. I had to use a VPN to be able to buy the product and deliver to my house in the UK.

I can understand a website blocking users from other locations or VPN users but for PayPal to do it seems unnecessary and a way to hurt genuine users.

ppyil··on The Linguistics of 'YouTube Voice'
This is increasingly common all over YouTube, and I've been noticing at university in presentations. The pauses seem unnatural and there is a lot of emphasis in strange parts of sentences.

Although I enjoy the content, CGPGrey (https://www.youtube.com/user/CGPGrey) uses this a lot and it is ever present in educational type YouTube channels.

ppyil··on Millennials are not f*cked
I don't think this really addresses the issues that automation raises. This article talks about how millennials have adopted technology with open arms but the biggest issue of the lack of jobs available isn't addressed.

Of course people will be quick to adopt the technology and of course millennials are best placed to take advantage of this but a millennial who lacks sufficient skills will suffer because of increased automation and this article just avoids the issue.

ppyil··on Emotions of Investing
Emotions (or sentiment) forms one of the three pillars of types of analysis for investments. The other two are fundamental (looking at a company's books and recent performance) and technical (looking at graphs and models).

Although this focuses more on the individual, market movements can occur due to shifts in sentiment and is one of the biggest drivers for change.

ppyil··on How to avoid the quant/developer black hole (2011)
For something like algo quants the distinction is a bit harder since there is a lot of programming involved for algos. I think a good question to ask is about R, Matlab and Python. They aren't really used in IT but they are used more by quants so would be a pretty good indicator.
ppyil··on China stocks hit hard, rest of world shrugs
Well it is the biggest drop single day drop since the larger losses in June/July so I think that it is justified in calling it a hard hit.
ppyil··on House temperatures as a metaphor for interest rates
As a non economist I was a bit lost by the end. What is the Wicksellian equilibrium rate and how exactly does it fit the analogy?
ppyil··on iSAX 2.0: Indexing and Mining One Billion Time Series [pdf]
Thank you. These are great for SAX but unfortunately don't implement iSAX. I'm working on iSAX for Python and will release that once it is complete.
ppyil··on iSAX 2.0: Indexing and Mining One Billion Time Series [pdf]
Does anyone know of any code for iSAX that isn't in C# or Java? I'd quite like to get stuck in but right now I'm using Python. I've got SAX set up but getting the iSAX indexing will take some time.
ppyil··on Ask HN: Google Maps vs. OSM in countries like India
The only way that I can think of being able to have extensive data is to make a separate scraper or something of the sort to look up a location and receive information of that location via the scraper. Such a method would be hard to configure, however.

As far as I'm aware, there are no out of the box solutions to this problem.
