I love the contrast between the 1st and 2nd link on HN right now (2014/06/06 10:49AM) http://gyazo.com/b5fb5ded81f2aab53cd4185c65158afa

That's arguable. I never had a chance to estimate this in earnest, but I have the hypothesis that the majority of HFT transactions are with one another. Sure, they collectively provide liquidity to non-HFT investors (because the order

I want to shed some light on this topic. As a former HFT quant, I find the general "Main Street" sentiment toward the profession to be misguided. 1. HFT does NOT take anything from most investors most of the time. Most investors t

Sorry for sounding like an ass, but I thought I would provide my slightly different perspective, precisely because Japanese was not particularly remarkable pronunciation-wise (but still interesting semiotics-wise) I contribute to one of the

Thanks for teaching me how to pronounce Japanese words! I am not all that familiar with the language. My limited experience includes being born in this little clubbing district called Roppongi, growing up in this little city called Tokyo un

In Japanese, the sign itself is called "attomaaku" ("at mark") but it's pronounced as "atto" when dictated. So someone's email would be johnsmith-at-gmail-dot-com, and if you ask a Japanese person to

Wow. If my HN top page analysis is correct, this story went from 5th place to 24th place in a minute. Probably got penalized for ring-voting?

Thanks a lot! Yea, I felt like a total n00b when I came to the web startup world a few years ago. This sounds ridiculous, but one and only database I had used until that point is kdb+ (kx.com). I had no idea about the performance/trade

I write a lot (in Japanese) on the web and have had some meaningful traffic. I think the most I got on a single day is like 150k visitors. And I've tried everything from raw HTML to SSG to Wordpress to a homegrown CMS. The truth of the

This is really cool. I can tell you guys actually know statistics. w/r/t testing multiple hypotheses, I've long wondered why false discovery rate never gets mentioned in the A/B-testing context. Any thoughts?

Thanks for sharing this. I think the truth lies somewhere between annual prepay and month-to-month. Most SaaS companies end up offering a mix of the two =)

by kiyoto 12y ago
As someone who works at a SaaS company, the annual prepay has one downside: it narrows the middle portion of the funnel (qualifying leads) compared to month-to-month. Of course, the biggest selling point of SaaS over licensed software is se

SQL is scary. I've talked to hundreds of customer prospects for Treasure Data, and by far the biggest surprise I encountered is how few people know their way around SQL. I am not talking about just "business" people but also

I agree. We hired our frontend engineer through HN. And it was surely not a dedicated link like the ones YC companies get to post but one of those monthly job boards =)

>Need a beefy RDBMS for 15mm rows? Maybe if you want to store the whole denormalized table in memory, but if you're just indexing a small field (or even partial-indexing a larger field) you should have no problem. Good point. Honest

You can say it's a bit of advertisement, but I won't call it a "shill". If I were doing that, I would have pretended that I magically stumbled on Treasure Data. Honestly, for data of this scale, I could have totally used

This one is one of their less commendable efforts: yes, there was a discrepancy between what Heroku's docs said and the actual behavior of Heroku's routing. No, RapGenius's simulation is nowhere near correct: multi-tenant res

Absolutely not. But it is also true that we no longer read anything unless the title is reasonably tabloid-y or it's got enough upvotes from other people.

As I understand it, Matloff's point is "to each his own" and "understand relative strengths and weaknesses of open source projects, but be very careful about making direct comparisons." Especially in the open source

We hired our frontend engineer, and he's been nothing short of awesome. To put this in context: We are an enterprise SaaS company (www.treasuredata.com). In other words, this is not something a lot of frontend folks are aware of let al
