danielharan··on Dr. J. Donald Millar, 81, Dies; Led CDC Mission That Helped Eradicate Smallpox
I have this dream that we could throw a huge party that day.
danielharan··on The Greatest Good: What is the best charitable cause in the world?
I don't think you know the numbers even after the fact. Knowing what worked doesn't tell you what probabilities you should have assigned.
danielharan··on Name Age Calculator
Has anyone used this to get inferred stats on a database of people's names? I'd be especially interested in applications for e-commerce analytics.
danielharan··on Is there a war instinct?
So, you're assuming Chimpanzees are acting on instinct, rather than culture?
danielharan··on We know where you’ve been: Ars acquires 4.6M license plate scans
An ideal tool for stalkers.

I am sympathetic that this data could be useful for law enforcement - however this data must not be released wholesale to the public and there should be limits to how long it is stored.

danielharan··on New Concept in Solar Energy Poised to Catch on Across US
Why do you think prices will go down? That's not at all what's been happening lately or the consensus estimate by analysts.
danielharan··on How Coal Kills
By grid parity, I meant people would be able to save money by installing it on their rooftops.

As for utility-scale, it's also smashing records, but that's a different discussion. $6c/kWh in UAE was a figure that surprised a lot of observers.

Regarding storage... solar coincides very well with peak A/C load, so the main use case doesn't require it.

danielharan··on How Coal Kills
Not only would that be very difficult to do, nuclear and coal have had decades of subsidies, giving them quite an unfair head-start.

In any case, by 2017 solar will be at grid parity in most of the US. By 2020 this won't even be a topic.

danielharan··on $2.25 Lyft line rides in SF
Companies need to make money to keep existing, the same way we need to breathe.

If you've ever had a tyrannical boss, you'll see sometimes the company is just their fiefdom. Feeding their ego is their prime motivation and organizing principle for the company - not generating money.

danielharan··on Thermos-Like Passive Homes Aggressively Save Energy
"The windows are one of the most expensive features,"

The obvious follow-up is what the 80/20 might be on these features. If going with readily available double-pane windows shaves $10,000 off the cost, it may be a decent trade-off - maybe use that money to buy some solar panels instead, aiming for net-zero?

danielharan··on Slaves endure 'a living hell' on remote South Korean islands
One way might just be to find a more cost-effective way to make that same salt, and put those farmers out of business.

A hack might be to use drones to run surveillance on those places.

The longer-term and stable solution is to have governments or community to care for those people so they are not homeless and vulnerable.

danielharan··on Good News You May Have Missed in 2014
As one noted in the article ""almost certainly an underestimate", because a number of climate-health relationships are not measurable due to lack of adequate data".

Milder winters expand the range of disease-carrying insects, increase risks of wars or famine with less water, mass migrations leading to political instability, more extreme weather events like draughts and flooding leading to failed crops and other natural catastrophes...

Meanwhile much of the WHO estimate is for people dying due to heat exposure. Easy to quantify, important to know - but nowhere near the full picture.

danielharan··on Meditation study shows changes associated with awareness, stress (2011)
(You mean elicit, not illicit)

Placebo might be a fair critique if we were talking about people's self-reported stress or well-being. Here we're talking about physical changes in the amygdala.

danielharan··on Pumpkin geometry: shadow sculptures that illuminate an ancient math technique
That has to be some of the best advertising possible for Shapeways.

Not complaining, just noticing.

danielharan··on Student’s six-foot water and solar-powered lens purifies polluted water
65C sounds like plenty enough heat over an hour.

Such temperatures are common in sous-vide (see e.g. http://www.douglasbaldwin.com/sous-vide.html - interesting headings to grep include "Pasteurized in Shell Egg" and "Computing the Destruction of Pathogens")

danielharan··on Nearables Are Here: Introducing Estimote Stickers
I'd love to use these to detect bike thefts.
danielharan··on Ask HN: Do bootstrapped billion-dollar companies exist?
For help selling the company? I'm sure there are a few VCs that know all the corp dev people and could more than double the final price.
danielharan··on The Jasons: The Secret History Of Science's Postwar Elite (2006)
Humiliating leaders and nations is not a valid reason to kill under most ethical systems.

It certainly does not fall under the precepts for a "just war".

danielharan··on The Jasons: The Secret History Of Science's Postwar Elite (2006)
Hiroshima was only necessary if it was the only way to get Japan to capitulate. This ignores rumours of back-channel diplomatic dealing that could have seen through a less humiliating exit for Japan.
danielharan··on NSA classifies Linux Journal readers as extremists
They don't need to transcribe. So-called "metadata" is what you'd be analyzing even if you had transcripts.
danielharan··on Evaluating Rails Projects
Running the same command on models... just crashes. Our God object (not User) weighs in at 1647.3. Yep, just one single model.
danielharan··on Evaluating Rails Projects
"For the controllers directory, expect higher scores; good scores are less than 20."

Ahem, anyone else run that and get scores like these?

$ flog app/controllers/ 7658.1: flog total 17.4: flog/method average

   174.4: BidsController#show              app/controllers/bids_controller.rb:17
   126.0: CompanyDocumentsController#update_verifications app/controllers/company_documents_controller.rb:85
danielharan··on Evaluating Rails Projects
Make sure you add all the extra dirs where code might be hiding

    ::STATS_DIRECTORIES << ["Admin", "app/admin"]
    ::STATS_DIRECTORIES << ["Cells", "app/cells"]
    ...
danielharan··on Why I asked to be removed from the Techweek 100
Were they actual attendees, or is that an assumption?
danielharan··on How I killed Mailcloud’s 21,000 users today
It seems like a minor distinction, however asking people:

"6 months from now, we end up failing. What went wrong?"

gets much better answers than:

"what are the biggest risks?"

danielharan··on The desperate hustle as a way of life
It's not sharing: it's renting.
danielharan··on AngelList’s Newest Experiment: a $25M Fund to Invest in Angel Investors
VC without having to pay for partners management fees to do due diligence, which is outsourced to high-performing angels.
danielharan··on What Heartbleed Can Teach The OSS Community About Marketing
"Polar vortex" has been in the lexicon of meteorologist for decades now.
danielharan··on Brendan Eich Steps Down as Mozilla CEO
Right. Bigots will have to stay in the closet now. Sounds terrible.
danielharan··on How Everyone Got the Top 1% Wrong
Wealth distribution follows a power law, so I'd expect the difference to be even more pronounced. The same with income as well.
