tagx··on Tesla's EPA Driving Ranges Didn't Hold Up to Testing
I exceed the EPA highway MPG when using cruise control for 100s of miles w/ little traffic. When driving manually or being a bit more aggressive with passing, MPG falls below the MPG estimates.

tagx··on Migrating Messenger storage to optimize performance
You can use the download your information tool to download all your data on FB, including all your messages https://www.facebook.com/help/212802592074644

A Brooklyn based artist did this recently and made a book of his conversation history (and covered an apartment with some of the pages). You can find a bit more information and pictures at https://www.halfspace.uk/messages-2011-2017

tagx··on Facebook Chats Are Being Scanned by a CIA Funded Company?
I wouldn't be so quick to assume foul play. Could it be some piece of software installed on the recipients browser/machine that is sending the links off somewhere to be scanned?
tagx··on Send Money to Friends in Messenger
You can add a PIN that you need to enter every time you try to send money
tagx··on Poll: Undergraduate Alma Mater
If we are currently undergraduates, should we answer "attended" or "do not hold a degree." It is important to be consistent.
tagx··on Shots fired at MIT - report of an active shooter near Bldg. 32 (Stata)
Apparently the shooters carjacked a Mercedes and headed towards Watertown (~7mi away) and are throwing explosives

Update: One suspect in custody

tagx··on Docker - the Linux container runtime

tagx··on Ask HN: Feedback for our Chromebook competitor
So the only difference between this and a chromebook is that it runs office?
tagx··on YC W13 Applicants
Now who wants to start a fantasy YC W13 pool?
tagx··on Security on an untrusted client - locking down a javascript library
"being able to encrypt a message is proof that they are who they say they are"

This is not exactly right. Encryption ensures people cannot eavesdrop on a message but it does not ensure you can verify the sender. You need authentication instead, which is what HMAC does in this case.

tagx··on “A Doable Sacrifice:” Y Combinator as a Married Man
Doable looks weird as a word. I read it as double. I believe it might look better hyphenated like do-able
tagx··on Filepicker.io (YC S12) lets content flow without worrying about bandwidth
We currently try to push people towards pointing the script tag to us so that we can more rapidly iterate on the product.
tagx··on Show HN: Hide Messages in Images with Steganography
I was hoping someone would pick up on the reference!
tagx··on Improving HTTPS Performance with Early SSL Termination
Static files are still served by a normal CDN. This helps with dynamic HTTPS requests that change each time.
tagx··on Improving HTTPS Performance with Early SSL Termination
We don't make any connections until the website calls us. At that point we load a personalized dialog for the user and we want that request to be as fast as possible.
tagx··on Improving HTTPS Performance with Early SSL Termination
It is a possibility. However, I've measured 86ms between east and west EC2 instances, 96ms between my client on the west coast and an east EC2 instance, and 15ms between my client and a west EC2 instance. Thus the additional latency per connection is only about 5ms.

For the total latency to be longer than 200ms, about 20 requests would need to be made on the same connection, which will not happen given the number of requests we do at a time.

tagx··on Improving HTTPS Performance with Early SSL Termination
We are using nginx. Newer versions support HTTP 1.1 backends (There is also a patch for older versions of nginx)
tagx··on Improving HTTPS Performance with Early SSL Termination
Normal CDNs don't do this with dynamic content that changes on every user request. Each api request we serve is different and saving 200ms almost doubles the performance.
tagx··on Improving HTTPS Performance with Early SSL Termination
No, the way it works is that there is a load balancer that terminates ssl and forwards it to nginx instances all in a private network. The nginx instances then have secure HTTPS connections over the public internet to the main load balancer that terminates ssl and forwards it over a private network the application servers. So this would be possible with any network since the cross country connections are encrypted.
tagx··on Improving HTTPS Performance with Early SSL Termination
Yes, but the SSL handshake has already been completed ahead of time so all the overhead is reduced.
tagx··on Improving HTTPS Performance with Early SSL Termination
No, the pool of keep-alive connections are all encrypted as well.
tagx··on Show HN: Ymacs - Emacs in the browser with Dropbox, GDrive, etc
The core of the editor is YMacs (http://www.ymacs.org/).

I just integrated filepicker.io. The source is at https://github.com/tageorgiou/ymacs

tagx··on Show HN: Impressionist with Filepicker.io, a presentation tool
I forked Impressionist (posted yesterday http://news.ycombinator.com/item?id=4364778) and integrated filepicker.io to make it more awesome

tagx··on Curiosity Sends 1st Color Panorama of Gale Crater
It's kind of strange how it looks like it could be a picture of somewhere on earth but it's really much, much colder
tagx··on Nobody will win the storage war
What is Dropbox's product in your opinion then?
tagx··on Filepicker.io now supports Instagram, Flickr and Video Recording
Interesting suggestion. Could you give me an example use case?
tagx··on Filepicker.io now supports Instagram, Flickr and Video Recording
I'm really digging the Gmail feature. What about allowing me to pull from my own ftp server?
tagx··on What hackers don’t know about business
We've realized that now and are in the process of changing our name. I'd love to chat with you about what you think of some of our ideas
tagx··on What hackers don’t know about business
Typo. Thanks.
