Don't use Hadoop - your data isn't that big
"So, how much experience do you have with Big Data and Hadoop?" they asked me. I told them that I use Hadoop all the time, but rarely for jobs larger than a few TB. I'm basically a big data neophite - I know the concepts, I've written code, but never at scale. The next question they asked me. "Could you use Hadoop to do a simple group by and sum?" Of course I could, and I just told them I needed t
女性ファッション誌狂騒曲～多難な新雑誌『DRESS』と講談社の見えない明日～(ふじいりょう) - 個人 - Yahoo!ニュース
2013年4月1日に創刊された『DRESS』（幻冬舎）。『STORY』『美st』（ともに光文社）を手がけた山本由樹氏を編集長に迎え、40代独身女性をターゲットに置き、結婚よりも恋というテーマに「女性のための幸せな社会変革」という遠大な目標を掲げている。 しかし、ネットにおける評判はおおむね悪い。広告が多くて独自記事が少ないというのを既に見透かされているだけでなく、そのペルソナ設定が素敵オーラを無理やり発散させているため「イタい」と見る向きが強くなっているようだ。 広告だらけ、中身が無い、必死すぎ……秋元康ら豪華経営陣が新創刊した雑誌『DRESS』に厳しいコメント相次ぐ（ガジェット通信） 見城徹社長によると30万部（そんなに刷ったのかよ…）のうち「７割の実売を確保すれば十分採算はとれる」とのこと。これは月刊誌で翌月号以降に部数の調整を維持するのに最低限のラインなので真新しいコメントではないが
:: Néojaponisme
This is an excerpt from our first print issue, NJP#1: Shōwa Tokyo. We started Néojaponisme in 2007 — a year that carried all the promise of the Internet as a hallowed bastion for reasonable, intelligent people who liked to exchange reasonable, intelligent comments underneath long-form essays about serious topics. Little did we know at the time, 2007 was the last year someone could harbor such misc

Vanity metrics: good for feeling awesome, bad for action. (photo source: UK Guardian) This is a guest post by serial entrepreneur Eric Ries. He was most recently co-founder and CTO of IMVU, which has more than 20 million registered users and generates $1,000,000+ in revenue per month. Eric is also a venture advisor to Kleiner Perkins.

Don't Be Fooled By Vanity Metrics | TechCrunch
Startups love to point to big growth numbers, and the press loves to publish them. We are as guilty as anyone else in this regard: one million downloads, 10 million registered users, 200 million tweets per day. These growth metrics can often be signs of traction (which is why we report them), but just as often they are not. It is important to distinguish between real metrics and what Lean Startup

A Course in Machine Learning
