anton_tarasenko··on Ask HN: Would you use a “git for data”?
Relevant: GitHub Large File Storage https://git-lfs.github.com/

On paying for this. When data operations are built around pipelines, it's often easier to re-run the pipeline or restore a snapshot. Which requires a good server, but not a service. So before paying, I'd check why the new tool is better.

anton_tarasenko··on Top 10,000 “Show HN”s 2006-2015: Where are they now? Please, share your story
Clarification: I collected HTTP response codes from top 10,000 "Show HN" projects published since 2006. Half of them returned 200. The others returned timeouts and redirects, which indicates that they perhaps get closed.

So, what's happened to them? It's interesting to hear your Show HN project's story.

And, yes, supporting links:

After SeanDav's question and minimaxir's comment, I summed up reposts' scores before computing the mean and the median:

anton_tarasenko··on Websites That Feed Hacker News: Top Sources of Submissions by Median Score
These websites have the low median score. That is, many submissions, many of them not relevant, so the median is low.
anton_tarasenko··on Websites That Feed Hacker News: Top Sources of Submissions by Median Score
A brief motivation for the parameters:

1. Sorting by the median. The mean is not very informative for the quality of the source. Most sources provide low-scored content with eventual hits that drive the mean up. The median fixes this problem.

2. Cutting off at 10 submissions. An arbitrary minimum to exclude pure luck from the results.

In the end, this ranking excludes websites like github.com and youtube.com, but it features some less known sources.

anton_tarasenko··on Ask HN: Is it possible to start a successful tech non-profit?
Being a nonprofit cuts you off capital. Investors are reluctant to fund nonprofits, which aren't going to generate value for them.

It's okay if a company doesn't need capital, but even tech firms take $50-100M a year to grow.

Again, if your sector consists of nonprofits, you may do fine. But IT and finance are for profit industries, with rare exceptions.

anton_tarasenko··on Ask HN: Is it possible to start a successful tech non-profit?
It's better to start with a problem and understand how to address it. For-profit companies would be an optimal solution for most human problems. Strong funding and control over business leave you with more resources.

If only non-profits work with your problem, then ask them what tech solutions they need. In some cases, they don't need technology at all, but rather funding or government support.

I would avoid "feeling good" non-profits that spend grands on noble but futile activities. Most useful solutions are those that people buy, instead of getting for free.

I'd be glad to point at non-profits in the area you're interested in.

anton_tarasenko··on Ideas are Cheap
The idea of using second-price auctions in ads sales gave Google tens of billions of dollars. Though Google didn't invent it.

Many expensive ideas are embodied in patents and code.

Cheap ideas exist, but not all ideas are cheap.

anton_tarasenko··on Best Time to Post on Hacker News: It's Irrelevant
Voting activity is proxy for reading activity. I don't have evidences that Saturday posting has more exposure than weekday posts given nearly the same upvote performance.

Agreed on making something great as the end. But delivering the product to the audience is important for niche products. Then factors like time, website, text become important (when they matter).

anton_tarasenko··on Best Time to Post on Hacker News: It's Irrelevant
Like this: https://news.ycombinator.com/newsfaq.html

"How are stories ranked?

On the front page, by points divided by a power of the time since they were submitted. Comments in comment threads are ranked the same way.

Stories on the new page and comments on the comments page are listed chronologically."

Now, try to find a similar answer for the websites like Facebook or Quora.

anton_tarasenko··on Best Time to Post on Hacker News: It's Irrelevant
I'd gladly look at this research. The research I saw is missing the fact that time is endogenous and simple scheduling won't work.
anton_tarasenko··on Best Time to Post on Hacker News: It's Irrelevant
Thanks for the correction about downvotes. Fixed.

As for the metrics, being on the front page seems to drive less motivated traffic. When a user upvotes the link, he cares. When the link gets to the front page, users click it because it's on the top, not because they're interested.

Hence, sales or whatever, but one should be interested in upvotes as the indicator, not the front page.

anton_tarasenko··on The Socratic Method: Teaching by Asking Instead of by Telling
You teach Socratic questioning as a habit (otherwise, you forget it). And as a habit, it requires repetition. Repetition, in turn, needs motivation. But the best motivation I know comes from people around. So, it's very non-techy.

And computers still do a lousy job in talking to people. Try to make people to answer a 10-question online survey. Harder to motivate than in face-to-face meetings.

anton_tarasenko··on Google Is Now a 'Tier Two' Employer, Says Recent Comp-Sci Grad
And adjusted for risks, even founders earn slightly more than the wages they would otherwise had in Google.

I mean, the whole argument about "bigger money" at startups is more like a myth.

anton_tarasenko··on Most Published Research Findings Are False–But Little Replication Goes Long Way
It's a bit trickier than the title says. By a "false" finding, they mean "a finding fails to yield the same result in at least one other study." But there's nothing wrong with failing a replication. See cancer risk factors research papers: they regularly yield results with opposite signs.

Rather, we should talk about "more research is needed to get a representative sample of studies of a phenomena."

anton_tarasenko··on Man Prosecuted for Price Fixing on Amazon Marketplace
That's up to government commissions to decide whether Amazon "tends to create a monopoly" with dynamic pricing. Amazon discloses nothing about its technologies to the public. What we see is, (1) Different prices for different users; (2) The conflict of interest with the merchants Amazon.com hosts, as Amazon serves both as a host and a reseller; (3) Amazon has an access to other merchants' traffic and prices, and is able to diminish their chances to compete with the service.
anton_tarasenko··on Man Prosecuted for Price Fixing on Amazon Marketplace
This, for example: "We do, however find some price variations for Kindle ebooks on www.amazon.com, depending on if the user is logged in to the site or not." [http://arxiv.org/abs/1307.4531]

Also see Figure 1 for the evidence of prices highly varying over time. It implies that different users pay different prices within small periods of time.
