tagx | 5 years ago | 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.

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

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?

You can add a PIN that you need to enter every time you try to send money

If we are currently undergraduates, should we answer "attended" or "do not hold a degree." It is important to be consistent.

Apparently the shooters carjacked a Mercedes and headed towards Watertown (~7mi away) and are throwing explosives

Update: One suspect in custody

So the only difference between this and a chromebook is that it runs office?

"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.

Doable looks weird as a word. I read it as double. I believe it might look better hyphenated like do-able

We currently try to push people towards pointing the script tag to us so that we can more rapidly iterate on the product.

Static files are still served by a normal CDN. This helps with dynamic HTTPS requests that change each time.

tagx | 13 years ago | 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 | 13 years ago | 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.

We are using nginx. Newer versions support HTTP 1.1 backends (There is also a patch for older versions of nginx)

tagx | 13 years ago | 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 | 13 years ago | 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.
