Comment Re:CouchBase (Score 2) 272

CouchBase/CouchDB is probably the easiest and most available one out there. It's particularly well suited for app backends too, as both the backend and mobile apps can talk to the same database, in theory eliminating the need for the backend to handle data syncing.

Those are good reasons, and it's also true that CouchDB will use a lot less resource overhead than a full-bore RDBMS under load. Depending on the use case, it might also prove decidedly easier to scale.

But the place where NoSQL really shines is storing amorphous or heterogeneous data. Because you have no constraints about what goes into a given record, you can record more or less name/value pairs at your whim. As with Perl, though, freedom comes at the cost of potential disorder.

But honestly, with the tiny amount of detail provided, it seems like it's really six of one and half a dozen of the other. If it's just call data being recorded, and the same call data every time, it won't make a huge difference if you use a full-blown RDBMS or a NoSQL database. Either one has its costs (individual PUTs and POSTs in CouchDB for example, can be expensive, whereas queuing and write contention might cause headaches at extreme scales in PostGres or Oracle).

Both an RDBMS and a NoSQL database will deal with replication fairly well, though my personal inclination is to prefer the simplicity of replication in CouchDB right up until the noise level gets out of hand.

And French intelligence bombed the Rainbow Warrior.

To their detriment. It's telling that the bombing of the Rainbow Warrior was the event that triggered so much outrage among Pacific island nations that the practice of atmospheric testing was finally stopped. It also wounded relations between New Zealand and France for over a decade, and resulted in a long period of Labour (i.e. left wing) rule. The Tahitian independence movement also made hay from the event.

It was, in short, a complete fiasco for the French intelligence service, and for the government of France, an unmitigated failure.

If for no other reason than realpolitik, governments need to learn to tread more lightly when it comes to abrogating the freedoms that make their societies as peaceful and prosperous as they are.

Precisely what is so surprising about the NSA spying on political radicals?

When you call Amnesty International politically radical, you debase the discussion. Amnesty uses non-violent tactics - mostly media relations - to shame governments into releasing political prisoners. If agitating against the imprisonment of your political opponents is radical to you, then perhaps you should revise your opinion on freedom and human rights.

Comment State Schools (Score 1) 370

Apply to a local state funded university. Talk with an admissions counselor about your goals and how well your associates will transfer (10 years old, the answer is usually Not At All). State schools provide the best bang for the buck. It also helps that their programs tend to be quite good. You also have to accept the fact that this isn't going to be convenient or easy. If it was easy to get a degree worth the paper it was printed on, everybody would have one.

If you just want to throw money at the problem and don't care about the quality of the degree, find the online program with the biggest advertising budget. Ideally somebody who can advertise on broadcast channels during prime time. The degree won't be well respected, but if you're doing this as a checkbox item it hardly matters. Just avoid taking on debt to do it. The private programs are expensive, and have a terrible track record for defaults on student loans (probably because of the expense).

Its sad to see these scientists cry fowl, controversy, and blasphemy at dissenters . Isn't science supposed to have opposing views, with fact-based research on multiple view points using the "scientific method" for cross-checking each-others work?

First off: Let's leave the chickens out of this, shall we?

Second: No, it's not sad at all. This is exactly the kind of debate we want - one where people disagree about specific and detailed issues, and respond to one another on points of fact. Yes, it's heated and the antagonism is distressful to some, but the plain fact is that this is real, healthy debate.

I don't see propaganda, mis- and disinformation from 'high priests'; I see a bunch of pencil-liner geeks getting furious with one another over data. And I like it.

The only thing that saddens me in all this is that people think disagreement is equivalent to enmity these days.

Comment Re:So is it 10,000 or 25,000? (Score 2, Informative) 220

Read, or don't read the article, your choice. But the level of sophistication will blow your mind.

No, no it really won't.

That article read like the opening page of a third-rate techno-thriller. Once you get past the alarmist dross, you see that people are busy pwning servers just as they always have. Only today - shock, horror - there are more servers around, and some of them are really badly maintained.

25,000 servers is a pretty useful resource for someone with malice in mind. And admittedly, it takes a certain amount of cleverness to amass that many. So yes, these guys aren't completely useless. But in the larger scheme of things, that number represents the lowest of the low-hanging fruit in the Linux ecosystem, and it's sufficient unto the day to know that if you (or your sysadmin) have half a clue, you'll likely not be bothered by this threat.


Submission + - Java 8 Officially Released (

darthcamaro writes: Oracle today officially released Java 8, nearly two years after Java 7, and after much delay. The new release includes a number of critical new features including Lambda expressions and the new Nashorn JavaScript engine. Java 8 however is still missing at least critical piece that Java developers have been asking for, for years.

"It’s a pity that some of the features like Jigsaw were dropped as modularity, runtime dependencies and interoperability are still a huge problem in Java," James Donelan, vice president of engineering at MuleSoft said. "In fact this is the one area where I still think Java has a long way to go."

'The economic return to higher education over a lifetime produces significant compound greater earnings.'

That has been true in the past.

Not exactly. You know what was true in the past? That a good education made you a better person.

Now, I won't deny for a second that there were numerous social and economic factors in getting the 'right' education from the 'right' schools. It's true that being a 'gentleman' was inextricably tied up with class, economic status and the clannishness of the privileged. But it was still about being the right sort of person rather than a more-or-less necessary precursor to employment. The cost in those days was primarily to keep the riff-raff out, rather than any reflection of economic realities (conditions in some British colleges, for example, were abominable).

In spite of all the hypocrisy and all the cant, a liberal education was designed to improve the person. It had little or nothing to do with employment, except inasmuch as employers at the time wanted 'improved' people for a number of lines of work.

Full Disclosure: It's easy for me to talk. I was one of the last people through a system that actually did focus on a decent general education, at a level of government funding that allowed me to finish 4 years of a double major with only $10,000 in debt, payable at a pittance a month over a ten-year term. I'm an arts major who's also a CTO, by the way.

also what about stuff like file shearing...

Well, typically, you start by grabbing the file by its strings, give 'em a twist and get it on its back. Then you lift the tail[*] such that all the loose bits run off onto the floor as you make your first pass. Some prefer Occam's Razor when shearing data, but I find Hanlon's Razor works, too.

[*] I find that tail -n 100 is enough to get a decent grip, but it really depends on the size of the RAM....
