ktamura··on Vis: A Vim-Like Text Editor
They are the utility scripts to start an editor window in Acme. B is async whereas E is sync (so that it can be used for the EDITOR env variable for software like git).

Not sure what they stand for for sure. E is probably editor. B might be buffer?

ktamura··on Vis: A Vim-Like Text Editor
Yeah. I've been using Acme for awhile now. While Acme itself is nice, what I really like is the B/E editor embedded in it. It's just a very simple editor that can be extended with _external_ programs.

Finally, I've come to appreciate using a mouse with my editor. Until I completely got rid of using most keyboard shortcuts (other than the most basic ones), I didn't realize how much cognitive taxes I was paying to retain and context-switch among different families of keyboard shortcuts. Mousing is so much more uniform.

ktamura··on How We Saved $132k a Year With an IT Infrastructure Audit
>For the longest while we’ve used fluent.d[sic] to log events in our systems.

As a maintainer, glad to see Fluentd there =) If folks have questions on Fluentd, I'd be happy to answer them here.

ktamura··on Outshone by Smaller Screens, PCs Aim to Be Seen as Cool Again
I have a friend who does exactly this. He has two NUCs, one at work and one at home. When I asked him about working away from his desks, he said, "I shouldn't be doing that =p"
ktamura··on Druid: fast column-oriented distributed data store
This is simply false. PostgreSQL + cstore_ftw, Presto, Impala, etc. all support "array oriented ability" via window functions.
ktamura··on Python, Machine Learning, and Language Wars (2015)
I totally echo this. In my opinion, if Python was the Linux Kernel, Anaconda would be Ubuntu: i.e., it ensures that you are actually up and running within minutes and not struggling in the missing-header-files or dependencies-management hell.

Of course, there's time and place for eschewing Anaconda, especially if you are trying to ensure your installation and dependencies are minimal. That said, for most data scientists who are workaday *NIX users at best, Anaconda is such a productivity boost.

EDIT: Actually, my analogy needs further qualifications. You _can_ get into dependencies/missing-header-files hell in Ubuntu, but it usually doesn't happen in the first few hour/days. Both Ubuntu and Anaconda have great "first 5 minutes to 5 days" experience, and that goes a long way in ensuring the adoption of underlying technology.

ktamura··on Thought Experiment: GitHub Community View
In my view, successful (and hence viable) open source projects tend to have

1. Centralized decision-making

2. Distributed contributions

While forking is important and necessary to experiment/test/prototype and iterate on various ideas, forking of a community is absolutely deadly. Look no further than Emacs/XEmacs or Node.js/io.js. It's very, very important that the ultimate decision making authority is concentrated on a few people with sound judgment (Often the creators, but not always).

On the other hand, development/contributions should be absolutely distributed: it accelerates development and makes it much easier for people to contribute to open source projects.

In fact, understanding this subtle difference between decision-making and development is what made GitHub successful: git was already a great tool for developing in the open. GitHub built a great platform for making decisions on top of it.

ktamura··on The Elastic Stack: Future of ELK Platform
Sorry to hear this. Can you give me the exact name of the plugin? I'd make sure to look at it.
ktamura··on The Elastic Stack: Future of ELK Platform
Have you had a chance to look at Fluentd? (Disclaimer: I'm a maintainer) Elasticsearch is far the most popular use case for Fluentd (much kudos to both the community and Elastic), and it's been pretty stable for awhile now.
ktamura··on The Elastic Stack: Future of ELK Platform
Curious if you had a chance to look at Fluentd (disclaimer: I'm one of the maintainers of Fluentd) If you did, I'm interested in your honest feedback.
ktamura··on Why GNU Emacs?
Neither, actually. In fact, I don't even consider myself to be a programmer (Although I routinely write scripts of sorts)
ktamura··on Why GNU Emacs?
Any Acme users here?
ktamura··on A Billion NYC Taxi and Uber Rides in AWS Redshift
Quite frankly, for data of this scale, PostgreSQL is more than adequate on a modern machine (although the OP's step-by-step guide is surely help for those new to Redshift)

For those interested in funny and insight analyses of the data, check out this blog: http://toddwschneider.com/posts/analyzing-1-1-billion-nyc-ta...

ktamura··on U.S. Supreme Court Justice Antonin Scalia has died
Indeed. While my beliefs have often diverged from the Justice's, his writing has been riveting to read and inspired me to improve my own.

America has lost a towering intellectual, and for that, I mourn today.

ktamura··on Google Open Source Load Balancer in Go
How does HN's duplicate link work? I'm asking this because I saw this thread earlier: https://news.ycombinator.com/item?id=10998103

Wouldn't it be fair for that submitter to get karma points?

ktamura··on The unsexy IoT
I totally echo the OP (Disclaimer: I work at a big data analytics SaaS with IoT customers called Treasure Data).

The "unsexy" IoT can be really unsexy. One customer wanted to get their data out of SCADA (www.scada.com), and as it turns out, the only way to get telemetry data out of their SCADA boxes was through emails as CSV attachments.

We ended up working with a third party dev shop to build a simple mail server that parses the incoming CSVs and send them to our backend so that the vendor could analyze the data coming from SCADA (which in turn came from heavy industry devices) using SQL, Salesforce, etc.

I never thought that MIME attachments would be a critical part in a "big data", "IoT" analytics pipeline...

ktamura··on Why Big Companies Keep Failing: The Stack Fallacy
Going off the tangent a bit but: did the original article actually talk about WhatsApp in the context of "going up/going down the stack"? Or, did it just appear in one of the subtitles?
ktamura··on Why we shouldn’t worry about leaving print behind
I am around your age, and while I _personally_ agree with you, I am also not sure about people that are born now: my friends' kids are playing with iPads and Android tablets (honestly, more iPads) just like I was playing with picture books, and looking at them interact with these digital devices, I have the suspicion that their generation will have a completely different relationship with digital devices for reading and beyond.

Of course, they are also given books in print and interact with them as well, but I feel that the verdict is still out there about how that generation will feel about print when they are our age.

That's a long-winded way of saying that neither of us is young anymore, and we _might_ be on our way to be less indicative of the future and more reminiscent of the past (Just _maybe_).

ktamura··on Aaron Swartz died three years ago today
I just got this book in the mail that collected aaronsw's writings: http://www.amazon.com/Boy-Who-Could-Change-World-ebook/dp/B0...
ktamura··on David Bowie Has Died
When September 11 happened, I was living in New York City, and like many other NYC residents -American or not- I was distressed.

Paul McCartney and Co. put together a concert to cheer us up (https://en.wikipedia.org/wiki/The_Concert_for_New_York_City), and that was the first time I had a chance to listen to Bowie live.

It turned out to be the last time. RIP.

ktamura··on Amazon Bought Me for $100 a Year
It's more like, my mother goes to the shop, the store person looks up the inventory, doesn't find the item, she asks them to order it, etc.

Prime usually delivers within a day or two, unless heavy snow closes off the only semi-paved road leading up to her place :-)

ktamura··on Amazon Bought Me for $100 a Year
Amazon Prime is successful for the same reason Uber or Lyft are: instant gratification relative to alternatives.

My mother, who lives in remote mountains in Japan, is a die-hard Amazon Prime fan. Why? Because it manages to deliver any item to her place across many SKUs. It's more convenient -and often faster- for her to order something on Amazon than to drive 30 minutes to shop at the closest electronics shop. I've been amazed with how good Amazon's logistics is even in rural Japan.

The elusive "aha" moment is actually not that complicated in theory: just provide value faster than alternatives while ensuring quality. In Uber/Lyft's case, it's a safe ride from A to Z arriving in a few minutes. In Amazon Prime's case, it's any merchandise on your doorstep. In AWS's case, it's computing resources at your fingertips in minutes.

It's easier said than done =)

ktamura··on How Stories Deceive
While Gladwell himself is notorious for lack of factual rigor (as a former math person, I especially wince at his "Igon value"), the New Yorker itself is famous for its rigorous fact-checking. In this age of fast-food quality writings littered with half-assed research or mere speculations, I appreciate the time and the effort that the New Yorker team puts into their craft.

At the same time, the New Yorker is indeed known for their over-the-top narratives. There's both pros and cons to this approach. For example, a great work of literary journalism like "In Cold Blood" and "Hiroshima" were first published on the New Yorker because of this editorial tendency. On the other hand, their long-form content makes their subjects less approachable to a large swath of English-reading (especially those who aren't native readers of the language) population.

ktamura··on Are ML and Statistics Complementary? [pdf]
They definitely are as far as their roles at (most) startups are concerned.

Unless your startup's core strategy involves machine learning, statistics tends to come handier than machine learning in the early days. Most likely, what moves your company is not a data product built atop machine learning models but the ability to draw less wrong conclusions from your data, which is the very definition of statistics. Also, in the early days of a startup, you experience small/missing data problems: You have very few customers, very incomplete datasets with a lot of gotchas. Interpreting such bad data is no small feat, but it's definitely different from training your Random Forest model against millions of observations.

ktamura··on Macs replacing PCs across enterprise at ‘unprecedented rate,'
There is actually one application that will delay, if not stop, the extinction of the PCs in the enterprise world: Excel.

Excel is by far the world's most popular business intelligence tool. Also, it is probably the world's most popular project management tool. In Japan (where I've done some business in), it also serves as everything from billing software to a mockup tool for digital products.

You might say that Macs have Excel too, but any business analyst types worth their salt know that the two Excels are vastly different.

Case in point: the very graph that shows the rise of Macs (quoted in the article and credited to IDC) seems to have been produced in Excel on Windows =)

ktamura··on Dropbox closing Carousel and Mailbox
When Carousel came out, I thought it was a great opportunity for Dropbox to go up the stack and blogged about it: http://kiyototamura.tumblr.com/post/82662241570/dropboxs-car...

Ultimately, I am beginning to think that Dropbox simply does not have the product DNA =/

ktamura··on One Year of Airbnb
No, at least not on NYT. On NYT, paid content/native ads are marked as such at the beginning of the article like this one: http://paidpost.nytimes.com/ca-technologies/apis-the-buildin... (Note the subdomain)

I must say that a lot of "paid content" pieces are pretty good, considering that companies are paying money to place these articles.

ktamura··on A CEO's Guide to Emacs
>Acme is a little less feasible for me due to not having found a proper (3-button + trackball) mouse to use with it.

I use Evoluent at home and HP's 3-button mouse on the go (http://www8.hp.com/us/en/products/oas/product-detail.html?oi...): while Evoluent is more ergonomic, it's too bulky to be portable.

ktamura··on A CEO's Guide to Emacs
Although I am not a CEO (but a marketer), I have a similar setup using Acme. I do all my note-taking inside Acme and have my plumbing logic set up so that all documents/JIRA issues/etc. are a single click away.

I think there is something to be said about using a few (if not one) text-centric tool to get stuff done: it's much lower on your cognitive load and wears you out less.

ktamura··on 15B More Reasons to Worry About Facebook (2007)
In 2007, I was just graduating from Stanford and vividly remember how my classmates perceived Facebook: they pretty much echoed Swisher's sentiment in the article. With the exception of a couple of really smart folks who wanted to "own" a significant part of yet-to-be-built Facebook, the most accomplished CS grads were joining Google in droves (Google was hot and on a hiring binge). Problems are Google seemed grander and more challenging and less toy-ish.

Microsoft was another popular destination at Stanford at the time. If Facebook was toy-ish and Google was cool, Microsoft was "respected". Many deemed Microsoft to be the McKinsey of tech: spend a couple of years there, build their resume and join or start a start-up. I even knew someone who took a job at Yahoo! over one at Facebook (Needless to say, most everyone who had offers from either Google or Microsoft chose them over Facebook).

Hindsight is 20/20 =)
