as a big data guy, every time i see structured data written in an unstructured, non standard, and possibly ambiguous and unparseable format i get the same urges. i think the best solution is separate logs for human consumption and machine

I've found the slowdown from hadoop to be very problem dependent. I've seen anywhere from no slowdown to 1000x slower. It sounds to me like those projects should never have been using hadoop in the first place. If your problem is not IO

If your working set fits entirely in ram on a single machine, hadoop is the wrong tool for the job. Hadoop is more about getting obscene IO bandwidth from hundreds of hard disk spindles going in parallel, not raw number of cores/parallel c

when it comes to starting a company, being a good salesperson is far more important than engineering expertise. i've considered switching just to be more well rounded. most software startups aren't actually trying to do anything difficult

i would certainly expect it to go through the charset in order instead of jumping back to a, but if you think of a string as a base 256 (or 26 in this case) number then it makes sense

a lot of it has to do with programmers bitching about bad programs way more than users of those other programs. he has obviously never used protools or any audio editing program. protools is one of the best out there, but it is still awfu

no one is going to buy facebook because anyone with enough money to offer a deal that zuckerberg would accept is smart enough to know that it isn't worth that much

yes that's certainly true. if there isn't a sensible option for a merge policy and non technical users have to resolve it manually you're fighting a losing battle in an AP system.

the best way i've heard it phrased is 'given the presence of a network partition, you must choose whether to maintain consistency or availability'. this does not mean that any network partition will make data unavailable if you choose C.

their requirements for data engineer make no sense. why would you need to know html, css, javascript, and web frameworks to do data mining?

it's some sort of fuzzy hashing technique. you have to run through every frame of every video and compute a number that represents that frame. to make the match approximate you have to come up with a hash function that is resilient to sma

GC only works while the drive is idle and should improve cell life drastically because you do a whole lot less read/modify/write cycles for small writes in the long run. Assuming a 256 GB drive with a write endurance of 1,000,000 cycles an

ssd's have spare blocks for extra life/wear leveling. ssd garbage collection can use LBA in combination with these spare blocks to always have cleared blocks.

that link is a bad test. they wrote 0's to the drive, which is bad because 1) empty nand flash contains all 1's and 2) writing 1's or 0's doesn't mark the blocks as cleared, you have to use secure erase

in a few years you might be able to build an electric car that is this simple. safety standards will still be an issue, but all you really need is a frame, steering, batteries, 4 wheel hub motors, and a computer.

if you worry about what laws you might be breaking every time you want to do something, you'll never get anywhere. i suspect that most new restaurants are in violation of dozens if not hundreds of laws, but in reality they either aren't en

it's amazing how many locked doors/gates/entrances can be defeated by simple tools. who needs a key when a screwdriver or a wrench will do just fine? the most common culprit is hinges on the outside.

agreed, deluding yourself into believing that you're below average is about as useful as deluding yourself into believing that you're above average. considering yourself below average at everything is indicative of low self esteem which is
