Tantalum ore concentrate currently sells for over $150/kg. Making metallic tantalum powder from the oxide is barely interesting even if the FFC process works quite well. Tantalum would remain an expensive specialty metal. Titanium dioxide, OTOH, is closer to $150 per tonne. A cheap process to convert that inexpensive raw material to metal would be one of the most impressive advances in industrial metal production in decades.

There's an ugly licensing fight in the history of the FFC Cambridge process. See the section "Commercial challenges" in this article:

http://www.saimm.co.za/Journal/v111n03p199.pdf

In 2000 Cambridge University Technical Service issued a sub-license for the technology that British Titanium Plc used for the purpose of producing bulk titanium and titanium alloys. BTi worked closely with researchers from the Fray group (one F of the Fray, Farthing, Chen inventors whose names make up "FFC.")

The US Office of Naval Research issued contracts to BTi for R&D work in 2000 and 2002. In 2002 DARPA started funding more expensive scale-up work also associated with BTi. In 2004 NASA issued an even larger contract to BTi. Cambridge spun off Metalysis in 2002 with another license, but Metalysis didn't seem to be making much progress compared with BTi. In 2005, CUTS revoked the sub-license granted to BTi and made all of the IP exclusive to Metalysis. The license revocation destroyed BTi.

My interpretation: CUTS crippled BTi because Metalysis wasn't making enough progress on implementation to compete against BTi. But CUTS really crippled the whole concept because the experts that had been working for and with BTi didn't want to work with Metalysis after getting screwed by CUTS. Metalysis "pivoted" to tantalum and has failed to make notable progress there, too. Maybe the application to titanium will finally resume progress toward industrialization after the patents expire.
This looks pretty cool, congrats!

I don't see how these satellites are physically any different than the many other, similarly sized cubesats that are equally difficult to track with the US Air Force/NORAD space-monitoring radar systems.

Reading the letter it sounds like they intend to ban cubesat-sized things owned/operated by US companies in general, because they're not capable of accurately determining their TLEs.

edit: I was wrong, these are 1/4 the size of a 1U cubesat. So very, very tiny.

A summary of the article's thesis (in my view), since it seems most lost the patience to read it:

The humanities is a culture based around the activities of reading works, thinking deeply about these works, then constructing criticisms of these works. The humanities should not have to justify their existence. They do not exist as some wish they did to further activist ideologies or to further traditional church views. The humanities should not have to justify its existence for its secondary or tertiary qualities (cognitive benefits, discipline). The humanities have created a class of people with similar tastes and ideas, and expulsion from universities won't make the humanities go away. Humanities exist because historically people have found value in this form of inquiry and these tastes, and people will continue to find value in these activities, so the humanities will continue whether universities accept them or not.

The linked FCC letter (https://apps.fcc.gov/els/GetAtt.html?id=203152&x=.) actually explained their rationale well (satellite too small to track with monitoring equipment so there was no way to warn other operators their satellite was about to be pummeled) and their idea to broadcast its location with GPS was not considered reliable enough.

Still seems weird the FCC and not NASA or the Air Force makes this call. Isn't the FCC busy diving into rooms full of gold coins from Verizon?

All the responses to you show how much a liberal arts education is lacking these days. I'm glad you home schooled your son. I'm sure he'll be a fine gentleman. The Clemente Course you point out is really eye opening. There's been so much doubt on "read a little Plato" and life will be better, that folks see more value in working at McDonald's. "I can make 12.50 an hour rather than waste time on Plato."
Satellite industry perspective here. I read the PDF copy of the FCC letter. It appears the FCC wants to ban them because the dimensions of each satellite are too small to accurately determine the TLEs of (two line elements) using the USAF/NORAD spacecraft tracking systems.

There is nothing RF regulatory mentioned in the FCC's letter.

Does this mean the FCC has stated a position that it has a problem with all cubesats of similar sized launched by all other nations?

It is kind of weird that the FCC is in charge of orbital debris mitigation and avoidance. If the US feds intend to regulate satellite dimensions and orbits it needs to be done by some sort of aerospace experts.

Oh, that is tiny. Definitely did not take that into consideration.

Having researched the data throughput/electrical load capacity of 2U through 6U sized cubesats somewhat, I am surprised that the Swarm company thinks a 1/4U cubesat will be useful for anything at all, other than very, very low datarate relay.

I don't think it's unreasonable to require that cubesats be at least 1U in size.

I would think a dystopian bent on the humanities would be much worse. They only exist to hide the real sins of the sciences' use (death, destruction, greed). Yeah, there is no justification... there is no science way to prop up the humanities. But if humanities teaches you to see in new ways, then you have to acknowledge that there's a hermeneutically useful set of tools on which science got based.
Claims in the blog post (orders of magnitude faster than the current state of the art systems, universal linear universal scalability from threads to many nodes, dimissing Dean's rule of redesign after x10 scale) seem overblown to me.

What have they really built: a purely in-memory KV store that doesn't support synchronous secondary writes for durability. So, any comparisons with ACID KV stores, either disk based (Cassandra, Mongo) or in-memory, are not apples-to-apples comparisons from the beginning. What could be production applications of such system, other than cache?

On their benchmarks: they don't really compare with state of the art.

Selection of competitors in the single-server, multi-core benchmark doesn't include systems like https://github.com/fastio/pedis. Also, they still use 100 millisecond granularity of gossip (within a single server!), while for all other compared systems corresponding metric could be evaluated as nearly 0 by construction, that gives Anna a huge edge.

In multi-node benchmark, they claim 10x over Cassandra. ScyllaDB (https://www.scylladb.com/) claims the same, while being ACID and linearizable, unlike Anna. Also, Anna achieves stronger consistency levels by holding off reads, that kills latency, given 100 millisecond gossip granularity. If it applies only to their multi-key consistency (Read Committed/Uncommitted) it's probably OK, because I suppose that there is no magic bullet that allows to preserve super low latencies and providing similar consistency in Scylla either. But if Anna needs to hold off reads for any of their claimed single-key consistency levels (all of which are weaker than linearizable), that's worse than Scylla. The authors of the paper didn't detail the algorithm for each consistency level.

Seems like the authors don't benchmark multi-node scalability of Anna on any consistency levels except the weakest, simple eventual consistency. It would be interesting to see if Anna scales as well on stronger consistency levels.

To me, the main outcome of this paper is another confirmation that shared-nothing, thread-per-core, message passing designs are beneficial in the modern computing environment. This is not new, however, see H-Store, Scylla/Seastar, Tarantool (https://github.com/tarantool/tarantool), Aeron (https://github.com/real-logic/aeron), Tempesta (https://github.com/tempesta-tech/tempesta), etc.

Novelty is the framework that generalizes thread/node scalability, different consistency levels reusing the same codebase, and having just a single knob - gossip granularity. Practical applications are limited. Certain techniques are probably going to be cherry-picked by systems such as Redis Cluster and In-Memory Data Grids.

There's not a lot of standardized titles and salaries in our profession. One company's idea of a "Senior Engineer" might be wildly different than another's. Either what level of experience that actually is, or how many hours/week you have to work, or not-salary things like 401k matching or bonus ranges, extensive travel requirements, etc.

I don't like the negotiation game either, but I don't really see how to avoid it.
I don't think it's irrelevant to a conversation where I explicitly said "what else can we learn from your data", but I understand why my looking for other conclusions from your data made you uncomfortable and made you use a weird "irrelevance" attack to discard the observations instead of actually responding.

I find it interesting that many of the folks who own everything choose Android (unless they need iMessage).

>if you can only afford a phone for $300 or you only want to spend $300 on a phone, you are going to pick Android because iOS isn't even an option for you.

Absolutely, you can get near flagship level Android devices for $250 (I just picked up a Moto X4 for $250 myself) while such an Apple device would be more than twice as much (and be unpopular enough that Apple's average sale is much closer to full price).

I think this data makes a very strong case for iPhone users having a very poor sense of value, regardless of whether or not you think this conclusion from your data is "relevant" to discussion of your data or not.

Maybe not colleges but schools. Someone I know went to prison. He was there for 5 plus years but learned absolutely nothing. Like it's been said, he came out worse than before.

I like the prison to become learning institutions rather that punishment factories. Continuous punishment makes people more resilient in a sense that they will fight and be willing to take more punishment and reject whatever they are being punished for. Eventually, these people get out, it would be nice if they were better than when they went in.

AWS Lambda doesn't support php natively currently. It came out with Node support, and has since added Python, Java, and C#. Of them Node generally has the fastest startup time, so if you want to run an unsupported language (like PHP), you build a binary for that language, and then write a small node script to call it and handle the input and output.
