tiplus··on Is Facebook eavesdropping on phone conversations?
It sounds like a creepier version of google now which listens for many keywords instead of just one, is it not?

Question for the experts: How much battery would it actually drain if the mic was constantly activated and the app was scanning for keywords. I mean, you could limit the scanning to times were someone actually speaks and otherwise remain in a sleep mode. The keywords are then synced only when the user opens the app.

Did anyone ever check if something similar was mentioned in the google now TOS?

tiplus··on Wait, is Facebook using their app to listen in on your conversations?
This seems too creepy to be true.
tiplus··on Chinese Midea makes $5B bid for KUKA
Kuka makes great industrial robots. They are pretty much the goto guys for car manufacturing robots from VW, BMW to Tesla. I do see how Midea would benefit from this deal as there are no competitive chinese robot makers, yet. However, in the long run Kuka's company culture and roots in Augsburg, Germany will not survive this deal (my impression). They are a 'small' specialized company in the huge industrial manufacturing market, a deal like this had to happen at some point.
tiplus··on Prenatal Fluoride and Autism
"Townsend Letter, the Examiner of Alternative Medicine, publishes a print magazine about alternative medicine." Why would this be published here instead of as a regular review article in a peer reviewed medical journal.

Why not contribute to Blender cycles instead?
tiplus··on Mpemba effect: warmer water can freeze faster than colder water
Erasto Mpemba boiled milk mixed with sugar to make ice cream. The original experiment is much more rewarding than simply putting water into the fridge. ;-)
tiplus··on DeepMind Health
I fear that AI will most rapitly be adopted in clinics for optimizing the diagnosis keys for which they charge the health insurance providers. This task is currtly done by human controllers and early expert based software systems.

This is were the big cash is.

tiplus··on How AI Can Predict Heart Failure Before It's Diagnosed
I am curious to know in which part of the analyzed datasets the heart failure information was hidden. I would have expected that they reanalyzed heart time traces but it was not mentioned explicitly, was it?
tiplus··on Why do so many people continue to pursue doctorates?
My experience was different.

1. It's a way to (pointlessly) delay adulthood.

adulthood != working for a company

Developing the next CRISPR, detecting gravitational waves, or building a stellator is a pretty grown up thing. In the end there is a non zero chance of achieving or contributing to something exceptional during your 20s (depending on your field).

2. Fear of the job market.

Well said. No other entity is recruiting young undergrads like academia does. Only topped by consulting firms, maybe.

3. Don't know what else to do.

The fellow students I encountered (~30) were mostly driven/obsessed by curiosity (2-3 exceptions maybe).

4. Magical thinking

Academia problem or society in general? This pattern prevails everywhere.

tiplus··on Obama Forgives Student Debt Of 400,000 Americans
I fail to understand the logic behind all of this. Why not give the money to the universities directly? It seems super inefficient to create a whole industry around funding university education. Even more so when this system needs to be backed by government bailout guarantees.

With 'efficient' I mean converting a large percentage of high school kids into university degrees / or better a highly skilled work force. Handing >$10^6 in debt to these kids doesn't seem appealing at all. One might argue that the economic pressure of the debt increases the overall productivity of a workforce. However, doesn't it rather create a predominantly sad workforce?

tiplus··on There’s Plenty of Space for One Trillion More Trees
Thank you so much for posting this, its so nice on a human level to think about turning mine laying tech into tree planting tech.

At the end they mention a planting capacity of 3k square miles per year which is a lot but still small compared to deforestation rates of 46-58k square miles per year.

tiplus··on Apply HN: SimShark 2.0 pays you cash for sharing your SIM card
Sounds interesting! Do you think my carrier would lock my card for violation of service? I am not sure if reselling minutes/data is allowed with standard SIM contracts.
tiplus··on Apply HN: Magako, AI for Math Tutoring
This has the potential to become a cool app but I think it should differentiate from other offerings in the features it provides to the user and not in the way the backend is implemented. You might want to tell people s.th. along the lines of 'look, my deluxe new AI gives you annotated solutions for hard math problem X which no other app can help you with...'

I am sure you are aware of http://math-42.com which is quite similar (developed by high school kids, afaik). They claim to use their own math AI, too. It might be very tough to compete with them without offering additional features.

Could you modify your AI to cover math problems which I cannot practice with math-42? Or maybe add features such as formula recognition with your smart phone, etc.

tiplus··on GitLab Pages
Well, their CI is pretty good for starters... compared to self hosting jenkins, or paying for Travis CI. Self hosting gitlab integrated CI runners is a big plus for me.

As a third party service provider you could still host and/or modify those CI runners for specific tasks like node, go, etc.

tiplus··on Ask HN: How much do you spend on your side project
$100/month sounds about right. Side projects are hobbies, for which $100/month is not too bad. Just compare that to the cost of operating a motorcycle, a set of golf clubs, owning a horse, building RC cars etc.
tiplus··on Google Puts Boston Dynamics Up for Sale in Robotics Retreat
It might be enough to include a cheap spectrometer to estimate the material composition. From this you should be able to guesstimate a suitable program. You could even spot and classify stains, AI to the rescue. There must be existing solutions for large scale industrial laundry handling.

A robotic closet that lets you wear your favorite shirt every day... fresh and clean.

tiplus··on Lenovo collects usage data on ThinkPad, ThinkCentre and ThinkStation PCs
Up until the Thinkpad X230, there was coreboot support which was great. However, with the new Intel chips now enforcing 'Boot Guard' this is no longer an option [1], is it?

I wouldn't be surprised if Lenovo decided at some point to also distribute malware modules for Ubuntu as well.

tiplus··on Volkswagen Stock Plummets as CEO Apologizes for Emissions Cheat
Test tuning seems to have a long history at VW. The VW subsidiary Porsche tuned the 918 spyder with a battery just large enough to pass fuel consumption test at ~78mpg, or 3l/100km which is ridiculously far from reality.

I am very curious, as to who wrote that patch. Afaik, almost all German manufacturers buy their common rail Diesel motor control units from Bosch. Stuff like pressure adjustment, valve control, or silly 'sports mode' buttons are all designed at Bosch. They ship a modular firmware which the manufacturers customize. Maybe VW were not the only customers of this special 'feature'.

tiplus··on Chaos Communication Camp 2015 Live Streams [video]
It always blows my mind that the CCC manages to host these huge events without being raided by police on a daily basis for massive copyright infringement on their public 10GE+ net. https://events.ccc.de/camp/2015/wiki/FTP They even provided rack space for the file servers last time I visited.

How is this handled at large US based hacker conventions?

tiplus··on User feedback on Pocket submitted to Mozilla
Somehow the part about privacy seems to refer to a 'special' form of privacy... look at FF hello:

Mozilla about FF Hello [1]: "Firefox Hello is provided to you in collaboration with TokBox, Inc. ("TokBox") and sends data to TokBox as a part of the function of the service."

Tokbox (Telefonica)[2]: "We neither rent nor sell your information to anyone. We don’t share your information with other organizations or individuals outside of TokBox, except as described below"

below: - "With our affiliates and trusted business partners that cooperate with us to provide you our services" - "We may share Aggregate Data publicly and with our partners."

Please try to contact Mozilla and tell me who these 'trusted business partners' are. I tried and did not get anywhere...

I am a former customer of Telefonica and they sure tried very hard to appear as a 'will mug you for money' type of company.

tiplus··on Firefox makes click-to-activate Flash the default
I am not sure the attack vector argument is 100% valid here, as flash replacement technologies constantly add attack vectors to modern browsers, too. Many traditional Flash features are now covered by webGL accelerated browser functionality, like accelerated 2D canvas elements. My guess would be that this browser-gpu bridge creates a whole zoo of GPU driver related security issues which attackers might focus on once flash is completely obsolete. (My money is on a remote code execution vulnerability in the Firefox Adobe DRM module.)
tiplus··on Live-Coding Blender with Hy
Don't forget about the fantastic cuda/opencl cycles rendering engine. The progress Blender has made in terms of scriptable photorealistic rendering is just insane.
