I am not sure about UFO sightings because it seems unlikely to me that aliens would approach us like this.
However, given the huge amounts of exo planets discovered everywhere around us in the last year or two, I consider it highly unlikely that we are alone.
Biomolecules are remarkably fast (picosecond timescales) at dissipating excess heat into the solvent, like heat from an excited vibrational mode. In order to cause serious damage through unfolding, I think, you would need much higher intensities than a few milliwatts from a cellphone. Serious local heating requires visible, UV light and above. Sunlight, however, does massive damage to all parts of your skin, including base pair changes in your DNA beyond epigenetics but your body has repair mechanisms, which recover changes and/or destroy damaged cells. Proof of cellphone induced damage would be remarkable.
If I got hit by a bus tomorrow - dying in the streets - I would not want to think about how I put 2.2 M$ in my savings account.
To get you started... you could try to think about the cliche "how to be the person selling shovels in the gold rush".
Write an online course on how you parametrized RNNs to predict Bitcoin markets. I got it to work well on predicting a certain low frequency event well with not too much effort. This resulted in 2~3 trade opportunities per day, making only very few $ each trade. So no luck in the gold rush but maybe not a bad shovel to sell?
Switch professions, maybe? 2.2M$ are not uncommon if you can wait a few years... Become a medical doctor and freelance across the country? Enter the middle management in any 200+ B$ company? Marry into a rich family? Low tier drug dealer in Europe (short prison times)? All of the above require working long/stressful hours over years. This brings me back to my first point: forget about the 2.2M and do s.th. you enjoy doing.
Congrats on your project! What a fantastic idea for (almost) passive income. You might even try to make the payment recurring and sell updates.
I had similar fears in my last appartment building (12th floor) after a deadly fire in the neighbouring tower. I ended up buying a long rope at a climbing outlet and some used climbing gear. There are also more expensive fire proof rope ladders but the rope worked for me.
If I understand correctly, the product is the database and its Tensorflow API?
I am wondering how this compares to the TALOS-N [1] server from Ad Bax (NIH) with 9000+ proteins in its DB? This, too, uses machine learning to 'fit' a predictor for secondary structure (dihedral angles) for backbone and side chain torsions based on chemical shifts.
I am worried about the dust this type of paper might produce when it is shredded or ripped, similar to the dust from rockwool insulation materials made from stone fibres. If I remember correctly, the persistence time of rockwool dust (current generation not 1970s) in your lungs is about 4 weeks, during which it is /may be cancerogenic?
I was puzzled when I first saw cross tab communication in impress.js for their slide control tab (slid.es) and I am still wondering about the proper use case of this feature today. Isn't this a security nightmare?

I would estimate the cost for three years like this:
- 1U single socket Supermicro Xeon E5v4-2630 10core+1GTX1070 GPU = 1500EUR
- operation costs (power+cooling) over 3 years = 1500EUR
- cost of 2 hardware admins 160k/year
- renting local rack space 15EUR/U
This equals about 145 servers for 3 years for us for 1 Million. The setup is highly optimized for _one_ set of data crunching tasks, not DB. We do not need much ram, or network but require a specific CPU/GPU ratio.
It's phase two (2020+). Once the tech is ready, Uber will have to order at an enormous scale with large discounts from whoever gets the contract. There were rumors that Uber considers Daimler as a car hardware platform partner. http://www.reuters.com/article/us-daimler-uber-idUSKCN0WK1C8
However, quickly there will be many new local competitors. Who wouldn't start such a business in their own local town anywhere? Buy a few cheaper autonomous cars (10 Model III+upgrades) and have them drive around your neighborhood. Call it 'EcoGreenCar LLC'. There will certainly even be an open source software platform to manage autonomous micro fleets.
The thing that worries me the most is that there is no public mirror of (important) OSS Github projects outside of the US, is there? It is all centralized in one place under one jurisdiction.
The guy is a physics teacher who invented a small wire bending device which is used to make the glasses locally anywhere at material costs of 1$.
Thanks, I guess I deserved the down votes for not reading this before.
I fail to see how this is HN related. Any hints are welcome.
Competitive Issue would be my guess...
That is all fine if your product sits on a shelf somewhere. However, if I understand the process correctly, they run physics based simulations of all the optical components in the assembly, order the parts and assemble on-site at the customer. It's like writing a back end where you can commit only once and that commit goes straight to the production server you just bought.
Sounds interesting, do you guys have a blog at mashtime? What kind of hardware/software do you use for training? Tensorflow? on AWS or bare metal GPUs?
Impressive tech, no question. However, I find it difficult to praise the technological advance of autonomous systems in any killing machine. I could care less about any cost savings for the tax payer in this context but I am glad that the pilot got to go home to his family that day.
Yes, I agree (in part). This stuff makes a lot more sense when you add climate / light control. Some plants are very difficult to cultivate, coffee for example (it needs constant temperature and will drop all leaves if you leave the window open on a frosty day). Others, like tomatoes, are difficult/impossible to get right if your garden is too shady (personal experience).
The energy costs for indoor climate / light regulation can quickly become outrageous compared to super market veggie prices. Therefore, I think this type of tech is for rare exotic plant, maybe historical even.
Imagine buying a piece of tech for growing historical coffee plants in your basement where you set the climate control to Kenia or Hawaii (buy the soil addon?) and which guarantees (as in `likely it will yield') you 2kg of your own personal coffee harvest per plant. This stuff has urban hipster $$$ written all over it.
A classic example of an "overspecific dementi",a complex answer where a simple one would have sufficed. However, in their defense, maybe this is the type of statement that expensive legal departments deliver by default as they consider it 'simple' and 'direct' compared to the stuff they usually write?
"Snell’s Youtube channel advertises many of the ship sounds he has collected as a sort of relaxing white noise for the geek set"
It works! :-) how cool...
I feel that the comments here are too negative, which ST2/3 does not deserve. ST is still a supreme editor and using/paying for ST is not a bad thing. Wasn't it ST which introduced the cool look&feel and features which Atom and VSCode now adopted? I love the ST ctrl+d select (even if it existed before).
PLUS: ST still has a super quick loading time which makes it a great addition to emacs/vi in some use cases.
Why does VSCode need a 'Pricacy Statement' (Help menu) which explains how Microsoft shares personal data? I get that it was written by MS, but why would I want a code editor that calls home? Or better ask does it send user/system data back to MS?
this cfg entry:

Enough ROS and ROS-I to control a kuka arm. http://www.ros.org/
So yes, kT is small on average (does fluctuate) and it is also 1 kT per degree of freedom. So yes, in principle a few hundreds of atoms could randomly fluctuate in energy to create this effect. However, this is hyper unlikely. I would be suprisd if it happened once in the life time of the universe. Also consider that you cannot create Maxwell demons[1].
Just in case, here is a video explaining it again [1]. I had to look it up myself.
kT is very little energy compared to a chemical bond. Take for example [0], they give an excitation energy for water of about 8 electron Volts which is ~750 kJ/mol, whereas kT at room temp is about 2.5 kJ/mol.

You are somewhat correct. In principle the system is quantized but due to the sheer number of degrees of freedom (or quantum states) the spectra may still appear continuous.
Take for example a single water molecule in vacuum: If you calculate the QM vibrational (motion of the nuclei) and electronic frequencies you would conclude that there is no way that microwave radiation can excite a water molecule. This is because the nuclei interact with three discrete (quantized) frequencies in the infrared (IR light), whereas the electronic degrees of freedom only interact with much higher energy photons (UV and above).
However, if you now move into the bulk, you will notice that there are is also an interaction energy between the water molecules which causes rapid changes in the water conformation at room temperature. From the quantum mechanical perspective, you now get an explosion of possible states including states which excite the hydrogen bond network between the water molecules. You can now induce translation and rotation of water with respect to each other. This is why water absorbs across a large spectrum of frequencies including radiation in the microwave region.
For DNA, the situation is similar. You will also find a continuous broadening of states. BUT how well you absorb energy at a given frequency still varies. Cell phone bands do not carry enough energy to break electronic bonds directly (unlike UV light). Instead, you can only induce thermal motions of the nuclei (heat). Luckily, our DNA transfers excess heat very rapidly (~picoseconds) to its environment, so no danger of local heating to the point of bond breaking if you don't climb up a massive cell phone tower.
In the end, its very unlikely that cell phone radiation alters chemical bonds in our DNA. However, beware of the sun while talking on the phone! I would guess that outdoor usage of cell phone significantly increases the dangers of cell phone usage. ;-)
To my knowledge, antibiotics inhibit crutial bacterial functions such as protein synthesis in bacterial ribosomes which causes cell death. To survive, the cell mutates its ribosomes which costs energy and makes them less efficient but functional again. If you are lucky, the bacteria need a long time before finding an efficient mutation. A combination of multiple such attack vectors can further decrease the efficiency at which the bacteria operate, giving your body an advantage. However, finding new attack vectors (which don't interact with human cells) takes on the order of ten years. So resistance is still a big Problem.
