sksk··on Google Apps Spam with No Way to Unsubscribe
Google Apps decides to include me in this email because some random person has decided to use my email ID as part of the sign-up. I keep getting these messages and I have no way to unsubscribe.

At least in other Google emails, there will be an option to disconnect but this one doesn't have it. The fine print at the bottom says this is 'mandatory'. I know I can apply a filter to get rid of it but that's not the point.

sksk··on Where Electric Vehicles Cause More Pollution Than Gas Cars
This economist article had a nice summary on this topic, 2014 (not about the same report, however). http://www.economist.com/news/science-and-technology/2163671.... The culprit is coal.
sksk··on Why is Stack not Cabal?
While I agree with you about pattern matches in Haskell but for completeness sake there is a ghc flag -W for it. If you compile this code with that flag, you will see the result below:

  --hello.hs
  f mx = case mx of
        Just x -> x
        --Nothing -> "NA"

  main = do
    let v = Just "5"
    putStrLn $ f v

  ghc -W hello.hs
  [1 of 1] Compiling Main             ( hello.hs, hello.o )
  hello.hs:1:8: Warning:
    Pattern match(es) are non-exhaustive
    In a case alternative: Patterns not matched: Nothing
sksk··on Tax-Free Debt: The great distortion
I would recommend that people actually read the referenced Economist articles instead of the blog: http://www.economist.com/news/leaders/21651213-subsidies-mak... and http://www.economist.com/news/briefing/21651220-most-western...

For those who don't have the patience to read more on this topic, the key argument is that debt creates perverse incentives. If you follow Basel II or III regulations, you will know how hard it has been for the regulators to convince the banks to increase their tier-1 capital. The banks are happy to pile on more debt rather than raise more equity capital (the purest form of capital) as debt is cheaper and comes with nice tax benefits. The financial crisis of 2008 was exacerbated because of leverage (another way of saying lots of debt).

While this can certainly reduce leverage in the banking sector, the author raises the question of start-ups vs. big companies. Big companies have massive balance sheets and will generally be able to borrow at much better rates whether or not there is tax incentive. If an up and coming start-up is amazing, I am sure there will be 100s of equity investors who will be willing to throw money at it. I wouldn't worry about this impacting them.

That said, this will not fly in the US. So much for logical reasoning.

sksk··on Max Levchin’s Affirm Raises $275M to Make Loans
>>..last four digits of his or her social security number, as well as behavioral factors like how long he or she takes to remember all that information. If that combination doesn’t quite add up to a loan,...

What I find really frustrating with most of these fintech companies is that they claim they use all kinds of data. But they don't really disclose whether this is used for 'underwriting' or 'fraud'. When it comes to underwriting there are specific FCRA guidelines on reason codes. For example, if they decline credit to a consumer because s/he did not type in their address fast enough, they need to tell them that. That would make for a good sound bite for the company.

Also, what if disabled people cannot type fast enough? That seriously touches on discrimination. Too bad CFPB is not going to care about these companies until they get to $10Bn in loan size.

sksk··on Disable sharing of Spotlight searches with Apple
It took me a while to figure out what is being disabled in the code and why I need to care. I care about privacy but I would like to understand what I am giving up. If I understand it correctly, the code disables 'Spotlight Suggestions' and 'Bing Websearches'. You can do it in the GUI easily. Just go to System Preferences -> Spotlight -> Search Results tab (uncheck the above 2).

Bing Websearch is clear enough but it took me a while to figure out what Spotlight Suggestion is. It looks like it gives you movie recommendations.

If there is more to the code, I would like to know what else I should disable. Also, ideally would like to know what I am giving up by disabling them.

sksk··on T-Mobile offers one-week network test drive, free music streaming
>> Notice how not all music streaming services are covered - only the ones that T-Mobile has approved here.

"During the announcement, T-Mobile’s John Legere assured the audience that their initial picks for streaming services wasn’t any sort of competitive/business move. Rather, it was a matter of technical implementation. They’ve got to manually configure the network to whitelist each service’s myriad data sources, so they picked just eight to start. The goal, Legere says, is to include “every music streaming service” in the program; moving forward, they’ll invite customers to vote on which services get added next."

sksk··on What If U.S. Cities Just Stopped Participating in the War on Drugs?
Gang Leader For A Day: A Rogue Sociologist Takes To The Streets by Sudhir Venkatesh (http://en.wikipedia.org/wiki/Sudhir_Venkatesh) is a great read as well.
sksk··on Numbers That Explain Why Facebook Acquired WhatsApp
I am not a WhatsApp user but a number of my friends use it. I think what they did well are: (1) You automatically upload your contact list to their servers. If any of friends start to use WhatsApp you will see it on the list (2) Smart phones were gaining adoption in many Asian markets and their value proposition of cheap unlimited messaging plan resonated very well (3) They charged for their product after initial adoption so they don't have to be tied to VC money forever and avoided annoying users with ads.
sksk··on Download a copy of your Gmail and Google Calendar data
Mac Mail.app can import mbox files but the default storage is emlx if I remember correctly for Spotlight indexing.

Thunderbird should also import mbox

I am a bit paranoid about my Gmail account so I use the Mail.app to download the emails and then I back it up. If my account gets locked for whatever reason, 'Download Data' option is not going to exist. So better to backup through other means as well.

sksk··on Introducing the Priceonomics Business Model: Data Crawling Services
Is this service going to be very different (in final output) from what you would get with http://import.io? Import.io takes the stand that we will provide you with the tools to scrape a page so they are not really the one doing the scraping (legally speaking). They also provide an API so easy to consume the scraped data in your programs.

I guess with Import.io if something breaks, you will have to redo the scraping logic. Maybe PE will manage that on the users behalf and that's their value add? Looks like PE may be doing some intelligent scraping as well (not everyone is going to list Dell LCD Monitors $400 in their title but they will do the normalization for you -- just a guess).

I have used import.io and it works very well for most sites and it is fairly easy to create a scraper.

sksk··on DigitalOcean Sucks. Use DigitalOcean
That's very helpful. Thank you so much.
sksk··on DigitalOcean Sucks. Use DigitalOcean
Would it be possible for you to describe your rdiff process a bit more? Do you dump the database periodically and backup that data or do you run rdiff on the binary data directory of your DB? Also, where is the rdiff backup data stored? I am guessing you would need another server for this and cannot be just Amazon S3? Thanks!
sksk··on Apple Reports Fourth Quarter Results
CNBC's summary explains the negative reaction to the earnings:

Apple posted better than expected earnings and revenue for its fourth-quarter on Monday, but shares still took a hit in after-hours trading.

The tech giant posted $8.26 a share on $37.5 billion in revenue. The street estimated the company would post $7.96 a share on revenue of $36.93 billion. But investors were disappointed with guidance for gross margins.

During the current quarter, the company expects gross margins of 36.5 percent to 37.5 percent, which missed forecasts of 37.9 percent.

sksk··on Google - Our History in Depth
Strange that Gmail is not mentioned in 2004 unless I am missing it! They mention Chat for Gmail but not Gmail?
sksk··on White People Love Hiking. Minorities Don't. Here's Why.
Shouldn't they be normalizing the percentages? i.e.,they should be looking at percentage of non-whites who camp (denominator total number of non-whites) as opposed to percentage of people who camp who happened to be non-white.

If a minority represents only 0.01% of the entire population, odds of finding them camping is going to be very low unless that said activity is something very, very common amongst that ethnic group.

Having said that, I somehow do not see a lot of African Americans when I hike/camp.

Thank you for the link. It was way more informative than the TC article.

sksk··on Calcutta girl who fled home & marriage at 17 returns as millionaire US innovator
This story is very sketchy. Couple of Google searches do not turn up anything useful about her beyond the standard PRish articles.

I tried looking list of people who have received honorary doctorate degrees from Harvard but couldn't find the entire list. But it is not in the summary list they have. (All this additional info from here: http://www.chandallc.com/index.php?p=1_4_About)

sksk··on 125th Birthday of Ramanujan
I a huge fan of Ramanujan and one of my favorite story of his is: Ramanujan was in school and his teacher was explaining the concept of division when the numerator and denominator are the same. The teacher says "if there are 5 people in the class and we have 5 apples, then each one will get one apple. If we have 10 people and 10 apples, then each one will still get one apple".

Ramanujan asks the teacher, if there are zero people in the class and there are zero apples, will each person still get one apple?

I am not sure how old he was at that time but going by the topic, must have been in middle school. Amazing how his mind worked even at that young an age...

I believe the story was also mentioned in The Man Who Knew Infinity (but don't remember if the narrative is the same or not).

sksk··on An Amazon Engineer Had a Little Idea That Turned Into a Billion-Dollar Business
I was hoping they will reveal the name of the employee who came up with the idea and give him the credit he deserves. That's what made me click on the link at least.

Anyways, if you are curious this link seems to have that answer (Ben Black): http://www.businessinsider.com/amazons-game-changing-cloud-w...

sksk··on Google Launches Credit Cards for Small Businesses
This looks like a co-brand card and so Google will not necessarily collect the interest revenue. All the risks and revenue are typically borne by the bank (there may be complex provisions so we will not know the exact deal structure for sure) and sometimes there will be profit sharing. Google will mainly save on the interchange (transaction fees) and may have a say on some of underwriting policies.
sksk··on How the Internet ruined San Francisco (1999)
David Talbot, founder and CEO of Salon.com recently participated in KQED Forum talking about 'How much tech can one city take?'. Somewhat similar to the above article but a 2012 view.

For those of you who are interested you can hear it here: http://www.kqed.org/a/forum/R201209250900
