hemancuso··on How Magic Leap Is Creating an Alternate Reality
Well that's not fair. The "occlusion mask" is referenced in a patent application, but basically is just a LCD that blocks out light that sits in front of your eye. re: fullscreen google glass, at best.

Seems like a screen in front of your eye that blocks out light.

By all accounts, they are working on some sort of device that projects a light field onto the retina. But that is strictly additive. You can't darken anything. This image you see of the elephant in your hand - no way to do that. At best it'd be rather transparent.

Unless there is some aspect of vision that somebody here would like to chime in on [locality on the retinal sensor allowing to perceive darkness by lightening up other areas?], color me deeply skeptical. It seems like "fullscreen" Google Glass, at best.

hemancuso··on Introducing Snapcash
I'd like to see a venn diagram of Snapchat users and people who actually know who/what Square is
hemancuso··on Event Notifications for Amazon S3

hemancuso··on Event Notifications for Amazon S3
Very cool!

Are there any ordering guarantees for these notifications? Specifically the order in which objects were created? It would be nice to be able to generate a meaningful event log.

hemancuso··on Mount Google Drive as a Virtual Drive
Also wanted to point out that a Linux version is in testing for those interested - linux@expandrive.com
hemancuso··on How Boston is rethinking its relationship with the sea
This article cherry-picks one idea among many. A better article:

hemancuso··on Unlimited Storage with Office 365 Subscription
Fair.

This is so we can use the API. It makes it sound scarier than it is.

hemancuso··on Unlimited Storage with Office 365 Subscription
I suppose we should put that up, or at least clarify.

We never capture/store any credentials. Everything stays on your client machine.

hemancuso··on Unlimited Storage with Office 365 Subscription
Encryption and Offline access are the two major features planned for V5 coming next year [All purchases get 1 year [or unlimited] of updates]
hemancuso··on Unlimited Storage with Office 365 Subscription
Late 2014:) It's in beta, ping linux@expandrive.com
hemancuso··on Unlimited Storage with Office 365 Subscription
You're the first to report that, ping support@expandrive.com if you haven't already. I've got gdrive mounted on my desktop now!

Shameless plug for my product, ExpanDrive

http://www.expandrive.com/expandrive

Mount OneDrive (and OneDrive business, soon) as a network drive in Mac/Windows (soon Linux!). Smart local cache. Access the data on demand without syncing the repo in first. Also supports gdrive, s3, sftp, Dropbox, box and more. Makes an unlimited account make a lot more sense if you only have a 128GB SSD. Use selective sync with the primary client to only sync a portion of your account. Then use ExpanDrive to offload the rest and access it as needed.

hemancuso··on Softonic fires 66% of its employees
450 employees!!?? At least ten times what I would have ever guessed. I'd be surprised if mac update had more than 4.5 employees.
hemancuso··on EBay to Spin Off PayPal
This articles suggests only 20% of PayPal will be sold, although I doubt that number is anywhere near final. It's just like EMC spinning off VMware. EMC held on to 80% of VMware [and still does?]. It lets them capitalize much more effectively on the faster growing subsidiary. Even today VMware trades at double the PE ratio that EMC does.
hemancuso··on The Dropbox terabyte conundrum
What would you pay?
hemancuso··on The Dropbox terabyte conundrum
Negative mouth to mouth because you had to go to the store to see the price options? There are two, fwiw. Lots of people pick the lifetime upgrade option.
hemancuso··on The Dropbox terabyte conundrum
Yup. Still beta but I'm using it!
hemancuso··on The Dropbox terabyte conundrum
OSXFuse is very well battle tested. We use it in ExpanDrive. CBFS by eldos is a commercial userspace filesystem lib for windows. We also use that.
hemancuso··on The Dropbox terabyte conundrum
That's exactly what the latest version does. Async writes. Large local cache. Stream out changes in the background.
hemancuso··on The Dropbox terabyte conundrum
Fair. I want people to download and not think immediately about price. It's not cheap. I see your point and you might be right. But it's not an entirely uncommon/bad pattern. I had a/b tested it a while back.
hemancuso··on The Dropbox terabyte conundrum
Yeah ExpanDrive is a full network filesystem. Air file is like a drag and drop ftp client.

iOS version is almost done. Tried to get it out for iOS 8 launch, but didn't quite get there.

Mount Dropbox as a network drive. Smart local cache. Access the data on demand without syncing the repo in first. Also supports gdrive, s3, sftp, onedrive, box and more.

Makes a 1TB account make a lot more sense if you only have a 128GB SSD. Use selective sync with the primary client to only sync a portion of your Dropbox. Then use ExpanDrive to offload the rest and access it as needed.

hemancuso··on Upgrading GitHub to Rails 3 with Zero Downtime
Am I the only one who read this as: tl;dr - don't get too far behind Rails, it's fucking painful and expensive if you do.
hemancuso··on Inside a Tesla Model S Battery Pack
Indeed, oops
hemancuso··on Inside a Tesla Model S Battery Pack
Isn't that the type of cell the 777 use(s/d)? I think Elon Musk very addressed the issue pretty well.

http://www.flightglobal.com/news/articles/elon-musk-boeing-7...

"Large cells without enough space between them to isolate against the cell-to-cell thermal domino effect means it is simply a matter of time before there are more incidents of this nature," he adds.

"Moreover, when thermal runaway occurs with a big cell, a proportionately larger amount of energy is released and it is very difficult to prevent that energy from then heating up the neighboring cells and causing a domino effect that results in the entire pack catching fire," says Musk.

"They [Boeing] believe they have this under control, although I think there is aUnfortunately, the pack architecture supplied to Boeing is inherently unsafe," writes Musk in an email to Flightglobal.

"The fundamental safety issue with the architecture of a pack with large cells," writes Musk in an email. "It is much harder to maintain an even temperature in a large cell, as the distance from the center of the cell to the edge is much greater, which increases the risk of thermal runaway."

hemancuso··on Introducing a more powerful Dropbox Pro
Distributed object storage

Filesystem: ExpanDrive :)

hemancuso··on Introducing a more powerful Dropbox Pro
It's easy enough to jam enough disks into a rack with these 90disk 4u super micro jbods. The thing that always scared me (ESP with rsync) is how do you get performant metadata for a few billion files? Or even tens of millions.

And raidz3 resilver must be horrible at those densities!

Again. Just curious. Email at jmancuso@expandrive if you feel like chatting. I know we offer a similar product, but we are about to leave zfs for the above concerns. Wouldn't mind sending some business your way.

hemancuso··on Introducing a more powerful Dropbox Pro
I meant in one filesystem. No obvious way to construct a single zpool anywhere near that big.

And if not one filesystem, curious how it would work in practice.
