Yeah, Ansible is something we are strong considering for managing docker hosts and container instantiation. As for building and provisioning containers, I would still argue that Dockerfile is superior for most of the work that needs to be done. Runtime configuration file templating is definitely something I'd like to see included in a Dockerfile definition, but until then at RelateIQ we are looking to a simpler solution than Chef for that and Ansible looks promising in this regard as well.
No, they lock the entire database for every write.
"MongoDB uses a readers-writer [1] lock that allows concurrent reads access to a database but gives exclusive access to a single write operation."
"Beginning with version 2.2, MongoDB implements locks on a per-database basis for most read and write operations. Some global operations, typically short lived operations involving multiple databases, still require a global “instance” wide lock. Before 2.2, there is only one “global” lock per mongod instance."
I'm speculating because I've never used play. But I have seen threads hung inside hashmap methods, eating 100% cpu when using a HashMap (which is not thread-safe) concurrently.
If you tap quickly (bouncing your finger off the screen) it tends to work fine. I believe the issue is that it is TOO sensitive, especially in regards to thinking you are trying to drag something.
If it let me install 3rd party keyboards and it solved the touch-sensitivity issues I'd keep it definitely. As it is, I'm very close to returning it. I'm hoping for a nice custom rom at this point.
While renting an apartment the dishwasher broke and I offered to install the new one. The landlord turned me down and scheduled it for a time I had to be at work and took the opportunity to snoop around and accuse me of harboring a child that I had not told him about (in reality, my niece would visit a lot so we had a bunch of toys for her). He withheld the entire security deposit on those grounds. So it cuts both ways with the unreasonable humans. :)
Happy ending though, because Chicago has fantastic renter's rights so we got all the money back and then some.
There is a lot more complication and loophole-ability in forcing ISPs to allow others to home their services than there is in forcing net neutrality in its traditional definition.
I'd bet there will be kiosks on site to find names, and there already is a website to find names that will point you to the panel: http://names.911memorial.org/
It being a default is not mutually exclusive with it being a choice.
I like the move, defaults should be used to push forward positive change and very few if anyone seems to have said they would rather not use CoffeeScript.
The end goal for every app doesn't have to be scaling on the order that GAE's original design provides. People have lived for years creating apps that use Excel or Access as a datastore.
Being able to use SQL on GAE will allow more widespread use of GAE for things besides "the next twitter".
This was a great write up. Redis and the community would benefit from having more writeups like this, detailing different successful real world ways to use it. One can read the Redis documentation and imagine many uses for its different data structures and commands, but to read about tried-and-working practices is fantastic. Of particular use, in my opinion, is seeing key naming/organization schemes that people are using effectively.
I personally would love to see the code for these and other use cases.
Wouldn't researching and discovering 0-day vulnerabilities be treading close to DMCA violations and/or cybercrime laws? I don't see why this information isn't causing Microsoft and/or the Government to go on the offensive legally against the likes of HBGary.
I'm a CompE and I interview countless CS and CompE's for entry-level programming jobs and they consistently fail horribly at business-logic decisions. More than 50% of the time, people with 3.5+/4 undergrad and 3.5+/4 masters can barely write a function and discuss the design decisions (e.g., recursive vs. iterative, caching) behind problems as simple as returning the Nth number from the fibonacci sequence.
I've seen over and over again that knowing the physics (well enough to get A's in class) behind a computer and how it stores integers is NOT enough information to deduce good patterns and practices.
