internet access on board the s

Does anybody know if the web surfing in the S enables downloaded applications like citrix reciever? If so are the applications user downloadable or does service have to do it? Is there virus protection for the on board computer?

Ron A. awaiting my s-class in March.

The browser is KHTML and does not have Java, Flash, or any video codec plugins so the Citrix receiver won't run since AFAIK it requires Java. Any apps that run in the browser will have to be written in JS, and KHTML's JS interpreter is remarkably slow compared to say V8 in Chrome, so you aren't going to get very speedy apps. There is no way to download any native code at all, so any vulnerability would have to be a bug in the browser or servers in the car listening for connections that allowed a buffer overflow attack or something similar.

I have been using Linux (the same OS as in the car) for nearly 20 years on servers and desktops, never running antivirus software (there isn't any available to speak of), running many more services than the car will (and therefore much more exposed attack surface) and I have never had an issue.

Hi jat

Thanks for the reply, I am happy virus protection is not an issue, but sad about the lack of ability to download citrix reciever. I am a radilogist and can remotely access images on my computer, ipad and even iphone using citrix and the PACS server software. It would have been very nice to know all I needed was my car, and just so cool to say, I have an emergency case to read, let me pullover and access the images. My only other hope would be to display the images from my iphone on the 17 inch display via blue tooth, or to be able to use a remote access package to view my workstation at work with the car screen. Maybe it will be in a future upgrade.

@RonaldA - there is work in progress for remote screen display via Bluetooth. I wouldn't be surprised if the Model S supports it when/if that happens, but it isn't going to be anytime soon. The browser is quite slow, so you really aren't going to want to run anything intensive on it anyway -- I find just using Google Docs to enter energy usage data to be painfully slow (plus it doesn't retain cookies between times you start the car, so you have to login [and go through 2-factor authentication in my case] each time).

It has been a long time since I worked with it, but I am surprised a radiologist would be making a reading on a low-resolution device. In the 90s, I worked with medical imaging and at the time nobody would consider using megapixel displays to read an X-Ray, and 4k displays weren't available then. Even besides the resolution which can be somewhat addressed by zooming into desired areas, none of the displays could do 12-bit grayscale either. We did get more traction with high-res pictures of tissue samples under a microscope, but not enough to make it worth doing. Do you find that a typical consumer screen such as on a tablet or phone is adequate for making a diagnosis, even though their color accuracy is poor?

@Jat: CT, MRI, and Ultrasound don't require high resolution viewing, particularly if you're just wanting to provide a preliminary report. X-rays are a lot more data rich and do require high res, though we're not commonly called for emergency x-ray interpretation and standard monitors are typically sufficient for a preliminary read. At least that's my experience. We commonly use our iPads or laptops for consultation.

jb is correct. For prelimi nary reads modern screens provide more than enough resolution to evaluate MRI, CT images. I wouldn't trust it for x-ray and certainly not for mammo.

@jbherman, RonaldA - thanks.

Sometimes it's really confusing to open a thread and read the topic post, and then skip the rest and read the last one or two posts.

That'll learn ya.

@olanmills - you don't think we would stick to a topic here do you? :)
