Hmm. Okay. I open a transaction for three days (let's say indefinitely), maybe reading a few tuples here and there and updating a few, but never committing. How does this system not fall over? I guess it could abort my transaction... Stil

Some sobering numbers, but I really dislike it when articles like these group "science and engineering" as an afterthought, especially in reference to prosperity. I'm an engineer, but have known a number of scientists, and the employment sc

That seems pointless, because then patches could not be distributed. Seldom are patches economically viable for exactly one person to create, one at a time, for themselves. That's the same burden of being a proprietary software company wi

Yes. When I saw this, it summons this to mind: http://xkcd.com/743/ I'm not sure if sparrow could have ever existed if it was open source. Maybe it could have. Maybe it could be released that way. However, if one is into the longevity

I've been dealing with this in quite a bit of detail in the last week. The answer is: it is entirely possible to write a Go program (or sub-programs, which is even better: use GC when you need it) that produces absolutely no garbage, and i

That's very interesting. Could you share your story with the mailing list pgsql-hackers a little bit? The guys who work on indexing are quite active on those lists. Also, there's some new thing I don't understand super well, sp-gist, do y

That's pretty neat. I use Trello quite a bit but have some of these these reservations, so I just gave Teambox a look. My initial impression is that it does way too much. There are a plethora of options and I just don't know what to do o

Somewhat out of date: in 9.2 there is a built-in JSON data type that is complete and committed. It doesn't have very many operators, though, intended to be used with some integrated procedural language like plv8 or plperl or whathaveyou.

The state of the art of this has advanced significantly with the advent of "extension" support, as seen in CREATE EXTENSION in 9.1+: http://www.postgresql.org/docs/9.1/static/sql-createextension.html The new way is much better than t

I don't think his behavior was at all out of the ordinary there for Linus, so if he lost credibility for you I don't understand why this would be only after this event. We'll see if it ends up being counter-productive after all, or if the p

Underreported but very useful are the omnibus GIN/GiST indexes for hstores, which let you index all the fields at once, not unlike the Postgres Full Text Search feature: http://www.postgresql.org/docs/9.1/static/hstore.html#AEN133... It's

I agree that things happen, but I think people are often suspicious that a vendor is making life more difficult than necessary systematically on the supposition that "de jure" need not match "de facto". Just a brief statement of intent and

They haven't lost anything, in the sense that savings appreciating slower than inflation is not losing anything, although few would suggest that this is not "losing" something. What has been lost is choice and opportunity for an easily iden

I think the regulatory environment for setting up a business, obtaining licenses, etc is somewhat orthogonal to how local laws and enforcement deal with (not only per letter of the law, but enforcement) fraud, spam, phishing, chargebacks, e

I don't think FDI is a very good indication for the challenges that a consumer payment processing company might encounter in India, especially in relation to their product.

It was very tightly delivered. It is pretty amazing that it either is the case or appears that Jeremy knows exactly what slide is going to follow the current one, sentence to sentence. For a one-hour-ish talk, that means many slides last

Hm. I think this is false, in at least one large domain: data management, and that's quite a whopper. Jeff Davis wrote about it better than I can: http://thoughts.j-davis.com/2011/09/25/sql-the-successful-co... Without any real data othe

As is always the case, disk I/O rather sucks for performance. On the other hand, Postgres's I/O scheduling -- while far from state of the art compared to proprietary databases -- is probably better than leaving it to the operating system

Not completely worthless: it does say something about the ease of getting good performance without having to know much about the ecosystem. But it doesn't speak to even the first "easy" 80% of what one would do to optimize performance, tho

Looking at the comments, I am shocked how many people are concerned that people will ship things with type errors into production or this would somehow relax the standards of Haskell programs, going to the length to suggest that some short

As a resident, seconded. Even living in San Francisco, the utility of a Caltrain connection is much reduced vs. BART. Was 10x too much to pay, if it is as the OP claimed? Maybe. As a former resident (and having grown up in) the east bay,
