Know what systemd was heavily inspired by? The MacOS X init, launchd.
You can find a full smart phone for $30 in the United States as well. But not everyone wants or needs a full smartphone (see: parents, elderly). Or they care more about battery life than features.
Considering the proliferation of programming languages out there, holding a spot in the top ten is respectable. Certainly not tantamount to self-mutilation.
It may not be the most popular option, but Ruby is hardly a marginal language. RedMonk has it tied for 6th with C++, PYPL has it at 10th, and TIOBE has it at 14th. It came off from the Rails high, but it remains steadily popular.
The ecosystem has actually got significantly better over the years, especially as Puppet, Chef, MCollective and others have driven popularity as an admin language, rather than a web language. But more importantly, JRuby pulls in the entire Java ecosystem, which actually puts it in a better position than perl or python, in my opinion. There is Jython, but that lags significantly behind C Python (current stable is 2.5 compatible, which was released eight years ago; their 2.7 release has been in beta for about 21 months) while JRuby offers Ruby 2.1 compatibility in their current stable release and will be putting out their release candidate for 2.2 around the same time as the Ruby 2.2 stable release.
The real win for me is JRuby. The Java ecosystem is at least as broad as perl, and generally better suited to enterprise applications. There are generally perl modules for everything, but they often perform far worse (e.g. Net::LDAP is probably an order of magnitude slower than UnboundID processing LDIF) or are just terrible code (e.g. Net::Sieve::Script which is a regex-based hack, rather than an actual language parser like jSieve).
2) Um, no. Objects cannot magically change their class, period. You might assign a different object to a given variable, but the language is strongly typed.
3) Huh? There are relatively few symbols in Ruby, as a rule. Are you referring to special variables (like $: $0 etc?)? Those are ancillary and not considered idiomatic these days. Don't like them? Don't use them.
4) Why shouldn't they? The first is a just a chained method. No different than "foo.split(' ').length;" in Java. I'm assuming the latter is supposed to be "num.to_s 16", which would be "Integer.toString(num,16)" in Java, but that is just because the Java designers weren't nice enough to allow you to pass a radix argument to the non-static method. There is nothing in the language that would have precluded "num.toString(16);" being valid.
Java is grand. Using jRuby to prototype, explore and extend is even better.
Looks far more like a smarter version of Sonos, at the same price point.
Don't know, don't care. The case against notability was stronger when it was first submitted, likely, but it is certainly hard to defend now. There are mature bindings for most languages, it underpins a number of higher level data stores (including OpenLDAP, of course, but also FineDB, Hustle), and is a supported back-end for a large number of projects (sometimes as a default component, as with CFengine and Zimbra).
If the rules legitimately preclude a page on LMDB, they certainly should preclude individual pages for MySQL backends like Falcon, Aria, and Toku, shouldn't it? And yet there they are.
LMDB was deleted from Wikipedia, not Python-LMDB.
The bindings are not especially notable. The embedded database is.
No, that's exactly what I read into the suits. Dealing with a deadly, incurable disease demands an excess of caution, even if the transmission rate is dramatically lower than other diseases. You don't need each patient to infect a hundred other people for it to spread; so long as it is more than one, it is a growing problem.
The risk here isn't because the disease is especially contagious; it is because the containment and treatment is especially costly. Doctor diagnoses someone with the flu, they send them home and tell them to drink plenty of wayer and get plenty of rest. In an extreme case, they may push IV fluids and keep a few days for observation.
With Ebola that becomes weeks of quarantine and treatment, stringent sterilization procedures, and monitoring anyone they've come in contact with. It wouldn't take an especially large outbreak to strain and ultimately exhaust available resources. And as necessity forces compromises in care and treatment by untrained individuals, transmission rates will spike.
Really not a viable treatment course. Even with monitoring and proactive care, your chances of survival are about even. In isolation, pretty much a death sentence.
