I created an updated version of that repo for a research project. Submitting a PR is on my to-do list. The changes needed to get search working aren't too bad once you figure out how the system works and where everything is. Updating the whole thing to more recent versions of Meteor was a little more annoying, in my opinion. There are also a couple of critical bugs in the code that need to be fixed before using it in production.
I went from Seventy Two to Sisty Four (sic) karma points all because of this stupid chapel. Get over your religious nostalgia and get back to real tech news... Thanks.
There's nothing technically novel about this. It's also kind of offensive given the mass genocide committed in the name of religion. Hacker News turning to Christian News.
Here's one excerpt, "Raised in the Georgian Orthodox faith, Stalin became an atheist. He followed the position that religion was an opiate that needed to be removed in order to construct the ideal communist society. His government promoted atheism through special atheistic education in schools, anti-religious propaganda, the anti-religious work of public institutions (Society of the Godless), discriminatory laws, and a terror campaign against religious believers. By the late 1930s, it had become dangerous to be publicly associated with religion.[97]"
I can separate the work of the man that created this from religion, and I don't see your link between this work of art and genocide. And that's from someone who strongly identifies as an atheist. It's impossible to see something like this that someone worked on for approximately 5 years and not both respect it, be awed by its technical mastery and to appreciate the fact that it came to us through hundreds of years in the state in which it is today.
HN is at absolutely no risk of becoming Christian News because of this particular link. If anything it shows that even the Vatican can go with the times, which means there is hope of further enlightenment in the future.
nature and nurture... you can't dismiss either. one is your genetic wiring (hardware) and the other is your indelible early childhood experience (firmware) ... and then there's your re-programmable self (software) ... His bio father being from that part of the world means his dad's genetic make is probably shared with 14% of Semites (Jews and Arabs of that area), 75% of south east Turks and southern Greeks, and 10% of sub-Saharan Africans. This is by no means an informed analysis of his dad's genetic heritage. Just an educated guess.
I know two identical twins (well they have an unidentical triplet sister as well). Interestingly they have reasonably different personalities - the nice one and the arse (relatively speaking).
Ah. Is Khosla Ventures related to Vinod Khosla? The same guy who sealed off a popular surfing beach in a small California town and declared it as his own? I always found that to be a terrible reminder of how money, greed and selfishness go hand in hand. Never mind me.
Buchwald based his decision on the 1848 Treaty of Guadalupe Hidalgo, which settled the Mexican-American War, and required that the United States recognize Mexican land grants as long as the owner filed a claim. The original owner of the coastal property filed such a claim. The U.S. government challenged his land patent, but the U.S. Supreme Court confirmed his ownership in 1859 -- 14 years before the California Constitution was first drafted.
I can't make head nor tail of this.[1]
EDIT: OK, this[2] is clearer:
The judge's ruling skirts the fundamental conflict between the rights of private property owners and the rights of Californians to access the shoreline. Instead, Buchwald rooted his decision in the land's history during the mid-19th century. Since there was no public easement attached to the property at the time the United States acquired California from Mexico, the judge reasoned, the question of whether the California Constitution now guarantees access to the beach is immaterial.
The original owner of the property was Jose Maria Alviso, who received a provisional land grant from the Mexican government in the late 1830s. He later transferred the property to his brother, Jose Antonio Alviso, whose rights to the property were upheld under the 1848 Treaty of Guadalupe Hidalgo, which settled the Mexican-American War. The U.S. government challenged Alviso's land patent, but the Supreme Court confirmed Alviso's ownership in 1859.
Wealth doesn't make automatically turn someone into an asshole (plenty of counterexamples). It does wreak havoc with one's social life and bring people out of the woodwork.
haha a legit question, but i guess you got downvoted because you could have researched it and shared it? dunno.
anyway. not a chem dude at all, but it appears III-V semis are when you combine:
"III-V compound semiconductors obtained by combining group III elements (essentially Al, Ga, In) with group V elements (essentially N, P , As, Sb). This gives us 12 possible combinations; the most important ones are probably GaAs, InP GaP and GaN." [1]
In other words, the materials in general are: Nitrogen, Phosphorus, Antimony, Arsenic, Bismuth, Boron, Aluminum, Gallium, Indium and Thallium.
I imagine nitrogen, phosphorus and aluminum are the easiest to find generally throughout the world.
China appears to control 90% of antimony [2] and its price seems to have gone up 700% over the last decade.
Arsenic seems to have major supply issues, one of the most critical in terms of scarcity according to [3] and [4]. Nevertheless, the price has gone down over the last 100 years significantly and according to this source is less scarce than it was a century ago: [5]
Bismuth is "relatively rare" but doesn't appear to be scarce. it is found mostly in Peru Japan Mexico, Canada, Bolivia and not in the USA. [6]
remaining elements are left as an exercise to the reader.
That is the question. All of the materials are expensive themselves (gallium, indium) or expensive to process ( silicon) - which means these cells will never scale and replace oil.
Which is why dye-sensitized solar cells are such a promising alternative, despite their lower single module efficiencies of ~15% (20-30% for the expensive semiconductors discussed in OP). http://en.wikipedia.org/wiki/Dye-sensitized_solar_cell
