Re:Show HN: Airtable, a real-time spreadsheet-database hybrid on Friday September 26, 2014 @04:51PM (#8374776)
Is pricing per user? It doesn't seem like it is, but that seems like a missed opportunity.
Re:Vagrant 1.4 on Tuesday December 10, 2013 @12:25AM (#6879117)
how do you launch boot2docker on your mac, raw virtualbox? or do you mean you actually dual-boot to it?
Re:Why Docker? Why Not Chef? on Thursday October 17, 2013 @11:23PM (#6569584)
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.
Re:MongoDB Raises $150 Million at $1.2 Billion Valuation on Friday October 04, 2013 @12:27PM (#6496307)
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."

Re:Why I'm Moving Away from the Play Framework on Friday March 09, 2012 @01:11PM (#3685221)
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.
Re:Why I'm Returning My Kindle Fire on Sunday November 27, 2011 @06:42PM (#3283743)
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.

Re:On Safety: A Word From Airbnb on Thursday July 28, 2011 @09:15AM (#2816575)
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.

Re:An algorithm for the Names at the 9/11 Memorial on Monday May 09, 2011 @12:25PM (#2529237)
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/
Re:Rails 3.1 shipping with CoffeeScript on Wednesday April 13, 2011 @11:58AM (#2442836)
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.

Re:Google App Engine to support SQL on Monday February 28, 2011 @02:04PM (#2272361)
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".

Re:Redis at Disqus on Monday February 21, 2011 @04:51PM (#2247371)
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.

Re:Black ops: how HBGary wrote backdoors for the government on Saturday February 19, 2011 @08:10AM (#2238958)
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.

Re:The most common phone number: 214-748-3647 on Wednesday February 09, 2011 @08:58AM (#2197380)
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.

Re:How Much Money I Made From Side Projects In 2010 on Tuesday February 08, 2011 @09:54AM (#2193011)
Pretty sure they are presenting a hypothetical situation where the revenues mentioned are worthless, implying that revenues are not the whole picture.

I believe they could (and probably do?) de-dupe at a lower than file level to handle this issue.
Re:Why 3D doesn't work and never will. on Monday January 24, 2011 @09:38AM (#2135234)
No offense to sound engineers, but Murch is not the foremost authority on the brain, the eyes, and whatever else goes into our processing of 3D. Further he hasn't offered any sort of proof, merely conjecture about why he thinks 3D should get off his lawn.

Sure, the current technology has some weaknesses, but as others have said, many found it awfully compelling in Avatar (many good reviews, and $2B in revenue).

Re:Ruby and Python: pivot points on Sunday January 23, 2011 @10:31AM (#2132527)
I may be missing something, but why isn't skipping your list comprehension maintaining the benefit of using a generator?

   >>> from itertools import chain
   >>> chain(*[['a', 'b', 'c'], ['d', 'e', 'f']])
Re:Down and Out on $250,000 a Year on Wednesday January 05, 2011 @09:35AM (#2071051)
Yeah, this article is really frustrating. The amount of money this family is saving AND spending easily puts them in the "rich" category, as does the kinds of things they are buying. Further, hiding the actual data in a scary-colored table (lotsa evil red!) and drumming up just enough expenses to put them in the negative stinks of a "researcher" with an agenda.

I suppose it is a relatively reasonable demonstration of the fact that people in our society tend to grow their expenses to match their incomes. Although, saving upwards of $50k/year (33+8+principal) is actually quite responsible and their ability to do it is essentially proof that they are NOT "barely scraping by".

I didn't downvote, but when looking objectively I don't see why its so bad. Someone is buying something below market value and reselling it at something close to market value (selling tickets seems to be a pretty competitive environment)

Personally I think monopolistic practices of Ticketmaster are far more reprehensible.

Re:The End of Public Funded Research on Tuesday December 07, 2010 @11:50AM (#1979602)
Is there an award number for airport body scanners? ;)
"Recreational use of the NAS is covered by FAA Advisory Circular (AC) 91-57 which generally limits operations to below 400 feet above ground level and away from airports and air traffic."

This is recreational use, and I consistently see people deferring to this "Advisory" circular which specifically states it merely "encourages voluntary compliance"
