Being ruthless with your attention can be a hard act to pull off without appearing rude.

According to the Wikipedia definition of ORM, it's primarly about the mapping of types: Object-relational mapping (ORM, O/RM, and O/R mapping) in computer software is a programming…

Usually the ORM has some notion of "associations" between models so that the data relationships are easier to navigate from the application side.

Yes, a mismatch exists and can lead to compromises as you try to use the object paradigm to glue the two layers together. But the benefits are also undeniable, primarily that of pr…

In what respects is the Vietnam analogy less meaningful than the rather banal battlefield analogy that you just made?

Maybe they didn't compare tough problems to Vietnam but my point was that good teachers often have a knack for translating difficult-to-grasp abstract concepts into the familiar an…

Most client drivers/libs for RDBs have basic type conversions for each language. You don't always need an ORM for this. If you have a ruby or python Time object, the low level db l…

You mentioned a "common approach". Is this the approach that you use or have you found a better way? The reason I ask is I don't quite understand how your description above correla…

If anyone could be accused of linkbaiting it would be Neward since he wrote the original article titled "The Vietnam of Computer Science". But I think it's less useful to think of …

I think the comparison to Vietnam makes sense as an analogy . The basic argument seems to be that each ORM imposes limitations specific to that implementation which may result in t…

How do you map the types if the rows are returned as dicts? Doesn't that become an application responsibility? By using an ORM you would not need to build that functionality, i.e. …

Going there now.

Excellent points and very well said. Recently I have been starting to feel down about myself and I noticed that it had to do with reading Hacker News and estimating my value throug…

But _why's contributions are largely irreplaceable. Sadly this is not true for anyone.

I appreciate that you say that because I do find it troubling that some people here seem to suggest that unless you are willing to take the kinds of risks involved in doing a start…

Yes. Something exactly like that. Thanks. One thing I disagree with in the article is the premise that people get real jobs because "it's the default thing to do". While that may b…

I have a sense that I'm one of these people. I'm risk-averse, perhaps anxious by nature, and I like the structure that corporate entities provide, despite being well aware of how c…

What kind of storage costs would they be paying for all that binary data? I'm guessing they're using Amazon Simple Storage, which is not expensive, but in that kind of volume I'm s…
