Comment: Useful applications for endurance athletes (Score 1) 57

by bsquizzato (#48524061) Attached to: How High-Tech Temporary Tattoos Will Hack Your Skin

Amay Bandodkar, a fourth year PhD student at UCSD, explains that the sensors are programmed to react to the amount of lactate the body produces.

This is an interesting idea. In endurance sports like running, cycling, cross country skiing, etc. there is a parameter that athletes tend to base their training around called "lactate threshold". It's basically the point at which your muscles being producing lactate faster than it can be "buffered" and it is believed this is what causes fatigue and "the burn" you get when you run too fast. You'll notice that if you run or cycle at an endurance pace (below your lactate threshold) you could continue that same effort for hours. When you go above your lactate threshold, you can only sustain that effort for minutes.

Currently the way it is commonly tested is like this (source http://en.wikipedia.org/wiki/Lactate_threshold): "Accurately measuring the lactate threshold involves taking blood samples (normally a pinprick to the finger, earlobe or thumb) during a ramp test where the exercise intensity is progressively increased. Measuring the threshold can also be performed non-invasively using gas-exchange (Respiratory quotient) methods, which requires a metabolic cart to measure air inspired and expired."

In other words you have to measure it in a lab, and you can't really measure it while "on the move". So you can imagine, it might be useful for athletes to just strap a patch onto their skin and have some wireless computer read out the data in real time (like a heart rate monitor)

Glad it helps. And as I've seen some other folks mention -- if the students will be signing in to Google Apps from a machine joined to the AD domain, and they already have logged in to that machine using their Active Directory account... then you could look into using Kerberos as the authentication method on the IDP instead of using an HTTP username/password form. So then, they truly only enter in their credentials once: when they sign in to the PC. Same principles still apply for sending the Name ID to Google, but the authentication step (step #2) would look a little different.

I see a lot of people here pointing you to articles on how to set up a SAML IdP. I mean -- that is a start -- but you may still be confused on how to solve your problem. If I understand it correctly -- you want your users to be able to sign in using "username", but have "username@domain.com" passed on to Google Apps, correct?

First, if you don't know what "SAML", "IdP" or "SP" is, read this: https://developers.google.com/google-apps/sso/saml_reference_implementation

Then the process, no matter what IDP, is going to be similar.
1) Choose your SAML IDP (OpenAM? Ping? ADFS? Others?)
2) Set it up to authenticate your users using AD based on their username -- in other words it needs to match usernames/passwords that your end users provide on the login page based on the "sAMAccountName" attribute in MS AD.
3) You will need to exchange SAML metadata between Google Apps and your IdP.
4) When you import the Google Apps metadata to your IdP and configure the SP for Google Apps, configure the IDP to tell Google Apps that your username is the "mail" attribute in the Name Identifer -- or, if your mail attribute in LDAP does not have the correct @domain.com you need, then you could use the Active Directory "Attribute Editor" and just assign some random attribute the proper "Google ID" for each user. Then pass this attribute along to Google as the "Name ID"

The nice thing about ADFS is it is so closely tied with Active Directory, so step #2 kind of takes care of itself. A guide for integrating ADFS and Google Apps is here: http://www.huggill.com/2012/01/12/setting-up-google-apps-single-sign-on-sso-with-adfs-2-0-and-a-custom-sts-such-as-identityserver/

When that author gets to the part on "Select Transform an Incoming Claim from the Claim rule template drop-down:", I'd probably do it a bit differently. I'd instead do this:
* Select "Send LDAP Attributes as Claims"
* Send the "mail" attribute as outgoing claim type "Name ID" (or whatever attribute you want to use in LDAP for your Google usernames)

What is graphic design? An art? A science? It's both. It's the science of using art wisely to get a point across, bring attention to something, create a focal point, whatever. There is clear theory associated with that kind of stuff -- about how humans react and process visually. I think usability falls along the same lines.

Even if a vaccine ever ends up being approved for HIV, there's no doubt that there is going to be a whole wave of controversy around actually vaccinating people, as is the case with the HPV vaccine. Since so many parents think that vaccinating their kids for HPV is just giving them another "green light" to have sex when they're younger, I am sure the HIV vaccine would be met with that same response, if not an even greater one. It will be a huge hindrance to a great achievement.

Wait, and this isn't Darwinism at work either?

Actually, the people most at risk are those who cannot be vaccinated: the very young, and those with weak immune systems. If not for them, I wouldn't care about this sort of thing; for those who choose to ignore science and lose their children to easily preventable disease it's nothing more than Darwinism at work, but it's a tragedy when people die because their neighbors are fools.

DNS doesn't have to be an issue, if the router can forward DNS requests. Most of the time in a simple home network the router serves as the name server for all the hosts inside the private network. It gets the real DNS IPs from the WAN, but all your hosts point to the inside router IP and it forwards DNS requests along.

It sounds like he wants to use the DSL as a *backup* for his Wifi, not run them both at the same time with complete split routing. But even still, you might be able to statically configure the router DNS and enter in both ISP's name servers. That way it'll do a lookup to both ISPs for a given hostname.

There's no details about anything in that article. Aside from the single picture of one 7975 phone showing RickRolled, it doesn't list vulnerable phone models at all. (Also strange is that the 7975 is a model that doesn't handle video calls on the phone itself, so I'm not sure how a video is playing on it). Despite that, the summary here on Slashdot tells everyone that Cisco's 7900 series of phones is vulnerable with the link given for its "Latest IP Phones". There's more models of phones that Cisco makes ... 3900 series, 500 series, 8900 series, 9900 series, 6900 series to name a few more (http://www.cisco.com/en/US/products/sw/voicesw/products.html#N4FD791). Of those, the 7900 is not the newest.

At least pull your facts from the article, please.

The only thing I want cable for is sports. More specifically, the one I care about most is NHL hockey. So, that's 1 or 2 channels out of however many hundreds I have to pay $60 for to buy in on HD/digital service. I would gladly rely on HD antenna for "general TV watching" and streamed media for the sports. I'm already paying for fast internet (from my cable provider, imagine that), why not make good use of it?

Well, thank God the NHL offers Gamecenter Live so I can watch NHL on my Roku! Oh wait, the NHL blacks out all my local teams games so that I either have to 1) go to the game or 2) buy cable to watch it. (yes, #3 option is a proxy. Which is against the service agreement, and is a big hassle in itself to get a reliable one unless I know someone with lots of bandwidth willing to run a reliable server in another city.)

Well, guess what, I don't care *enough* to pay the extra $60 to watch my local games. And I'm not enough of a sports nut to watch all these other NHL teams play, and I'd guess I'm not the only one that falls into this market demographic. You could have our subscriptions NHL, but with these stupid policies you get $0.
