That feature is included with every new account!

That "weirdly shaped enter/return key" is an ISO standard.

mdellabitta··on HFS+ is crazy
I was responding to the comment "You wouldn't put the entire content of a file in an extended attribute, would you?" HFS+ does, although in this case, it does without leaking that detail to callers.
mdellabitta··on HFS+ is crazy
Actually, I believe OS X does this for small files in order to not burn a whole filesystem block on a sub 1k file.

"In Mac OS X Snow Leopard 10.6, HFS+ compression was added. In open source and some other areas this is referred to as AppleFSCompression. Compressed data may be stored in either an extended attribute or the resource fork.[13] When using non-Apple APIs, AppleFSCompression is not always completely transparent."

mdellabitta··on HFS+ is crazy
Just a datapoint: Macs have been sending files via the Internet with resource forks for a long time, basically since the invention of the Macintosh: https://en.wikipedia.org/wiki/BinHex

Resource forks are basically legacy from the original MacOS, and something that's being retained for compatibility, not something that's really a current design. The current replacement of resource forks is bundles, where a directory masquerades as a file in the GUI.

There are lots of reasons to hate on HFS+, but I wouldn't consider this the most important one.

mdellabitta··on Why Rdio died
Just as a alternative view: I was a Spotify user but their Android app was unreliable... my phone would hard reset occasionally. Then I started using Google Play Music.

Ding ding ding.

Also, hello from Indian Point, Buchanan, NY! I can see a containment dome as I write this.

Next up on my Snake Plisskin-esque commute is literally going through Sing Sing prison: https://www.google.com/maps/@41.1506265,-73.8700067,613m/dat... (those train tracks are the Metro North Hudson line, among other things)

> The key to a successful nuclear reactor of any kind is to generate, confine, and control a blob of super-heated matter, called a plasma — a gas that has reached temperatures of more than 180 million degrees Fahrenheit.

Um, what? I'm about to pass a nuclear fission plant on my way to work, and I surely hope there are no plasmas in that.

AKA, they mean fusion reactor.

mdellabitta··on Kilogram conflict resolved at last
SI and metric are actually subtly different. Do any countries actually use SI rather than metric?

One kg of water is definitely one kg.

mdellabitta··on Texas Teen Still Suspended Despite No Charges, Will Change Schools
That's funny, I would have thought the utter lack of anything explosive would differentiate it from a bomb. :)
mdellabitta··on Why WhatsApp Only Needs 50 Engineers for Its 900M Users
I guess I'm not really thinking this is a hardship on the interviewee, but wondering more if you're implicitly filtering your candidate pool. But you make good points.
mdellabitta··on Why WhatsApp Only Needs 50 Engineers for Its 900M Users
Does this interviewing methodology mean that you only hire devs that don't currently have a gig or have vacation days to blow on the possibility of getting a job with you?
mdellabitta··on Amazon Web Services in Plain English
Is that another plain-English name for EC2, as well?
mdellabitta··on Expresso? The x spelling has considerable historical precedent (2014)
That raises the question: What would be the 'natural' English spelling of other Italian words, like 'pasta' or 'gnocchi'? Which highlights the slippery slope we're on here...
mdellabitta··on AWS S3 Having Problems Again? (Monday 12PM Pacific)
IIRC, the AWS console itself is hosted out of us-east-1. Which means you're always somewhat exposed to whatever failure modes it has.

mdellabitta··on Miles per Gallon
Of course, you'd probably do a little better than that, because at no point would your car be carrying all of that gas. But the trough would have to get wider when you went uphill or had to get going at a light.

Except this won't work with files bigger than 5gb. It might be worth the time to do it right.
mdellabitta··on The sad state of sysadmin in the age of containers
So everyone who runs Hadoop is installing junk? Seems like plenty of other companies have been able to build businesses on it without adhering to your Debian-only rules...
mdellabitta··on The sad state of sysadmin in the age of containers
But Debian isn't the Debian of Hadoop. Cloudera is.

Why should we assume the Debian Foundation is the sole trusted source of every type of software?

mdellabitta··on The sad state of sysadmin in the age of containers
> The value of debian is not that they package (or repackage) everything into deb files but that they resolve versioning and dependancy conflicts, slip security fixes into old versions of libraries (when newer version break API/ABI), and make it possible to integrate completely disparate software into a system. They also have a great track record at it.

The analog of the aspects of what Debian does that you're talking about here in the HStack world are companies like Cloudera, who, surprise, make their stuff available as debs and PPAs.

Building your own Hadoop from source and complaining that the resulting product is unvetted is sort of like doing a git pull of all the Linux dependencies and building that.
