Safe, also means that the application does not crash in funny ways with segmentation faults. Which is something that banks like a lot.

In my first job I made 15 euro's an hour and was billed to the client at 125 euro's an hour (this was as a java dev in the Netherlands 8 years ago).

If you produce it but no one buys it what was the point? In fact in reality if you do that you wil pay a lot to the grid maintainer for this. Capacity factor is % utility of your max generating power output.% utility is lower if you can&#x2

That is only in the last decade, and for the US. Other countries and decades have differing numbers. Still it only holds when Nuclear is a less than 50% of production. France tends to have around 77%.

That is really hard to determine, mostly because project costs are part of the greater EdF numbers and not broken down in details for those years. So someone with better French and access should be able to answer you there. This is true not

Flamanville, at 10.5 billion euro for 1.6 GW is not nearly as good as watts bar 2. This has had serious delays due to quality issues detected by its regulator. As had the finish and Chinese units build to the same design. Sure these are sup

I would be interested to hear what a similar capacity highway on the same stretch of land would cost. I would be extremely surprised if that would be an order of magnitude different.

90% is a best of fleet number. But for economic analysis you should really assume a lower number, unless you can guarantee that you are the cheapest producer at all times. As demand during the day can be near double of that in an area durin

I like cypher, then gremlin for small queries. The problem is the queries I see are much, much larger. And at about 10 lines in the use of white space in SPARQL starts to make a real difference in readability in my opinion. That can of cou

I am just going to point to our work at sparql.uniprot.org. A graph database with 17 billion edges and 3 billion+ nodes. Containing in its whole the NCBI tax and GO tax trees. That you can access for free over HTTP using standard SPARQL 1.1

I always wonder how readable those queries really are. Its a nice claim but has anyone done any really serious research about this at all? For example the same in SPARQL 1.1 SELECT ?cypher_attributes WHERE { ?cypher a <QueryLan

I know that the Graal JIT guys are working on chained function call fusing for inlining when generating machine code etc... But I am not sure that is what you call "fusion". There is definitely only one iteration over the collecti

JIT gives you more information about how the program is actually run. This allows a large number of optimistic optimizations that GCC etc... can not make. This in theory allows faster code to be generated. Than ahead of time compilers can.

Line loss in US in 2007 was estimated to be 5% in 2013 ( http://www.eia.gov/tools/faqs/faq.cfm?id=105&t=3 ) For gasoline the number is supper tricky to determine. So here comes a back of napkin number A fuel tru

Gasoline also has large transportation inefficiencies. Unlike solar, every garden a refinery and oil well is impossible while every roof a solar pv is possible, even if 100% unlikely.

Ah ok, so in RDF terms each predicate gets its own table, which makes sense. Then you have a subject foreign key relation ship and a object foreign key relation ship to the node tables. That would be better than one big table in performance

A lot of the early academic RDF graph databases used this approach. However, performance was no where near to what is required. This let to for the SPARQL/RDF graph databases to now a whole set of independently developed stores. Some

They are super cute, but not really suitable as pets (like all pigs they like to dig). Still it shows that precision gene editing gets the same effects as focused breeding, just faster.
