- Capability to handle HTTP and the general "server stuff" (already exists not too worried about that)
- Some way to connect to a database (ODBC) and transform data into something that feels natural in said language i.e. ORM for OOP languages
- Render said data in a browser in some way (e.g. create views for data)
- REST interaction with the data

Just follow what Express does,
https://github.com/visionmedia/express

There's a reason it has over 10,000+ stars. It gives you ultimate flexibility while providing all of the core functionality you would expect from a low but not bare metal web framework.

You'll noticeable quickly it has no ORM or any notion of a "model". That should be up to the user to decide on a per project basis and they should plugin any type of mapper they want based on the db tech they chose.

Arch: Aside from the initial installation, it is probably more beginner friendly than you may think. Yes, pacman is the total nuts.

I took a one month contract at literally the most hipsterish place I've ever seen. Not sure what to make of that. "Sadly", all of these people seem really nice and really good at their jobs.

Clowntable, I look forward to your feedback on LightTable. Oddly, I haven't been too excited about it. I get the vision, but its not something I want to be an early adapter for.

I guess LightTable doesn't have paredit mode, which would probably make LT terrible for Lisp development. I just learned about this, and I'm quite surprised considering the history of Granger and LightTable.

Just had my first programming related phone interview.

The three OOP questions she asked me where:
1. Name all of the different types of loops.
2. What is the difference between call-by-value and call-by-reference
3. Explain inheritance without using programming jargon

Seemed a little too easy. Is this standard?

Phone screenings are not meant to be overly technical (especially if you are new grad). They are meant to screen for basic technical competency because most new grads are frauds and embellish the resume.

@tyler, in all seriousness, your answers indicate more intelligence than aswering that question earnestly would

EDIT: about types of loops

lol, but only true if this screen is administered by a technician and not (as is more likely) an hr drone with a written script.

yeah she introduced it as "I'm going to ask you a few OOP questions" and after the first two I was sort of like 'lolwut?'

Answers to the first 2 are silly to type out.

The last one I used as an analogy that a BRANCH of Bank of America is an instance of the more general, Bank of America.

less silly that you think, i expect.

that is not an example of inheritance.

srsly?

I explained it in that the branch has all the properties that the main bank does, has all the functions and abilities, but also can/does have additional properties and functions.

based on your explanation, i'll upgrade that to a poor example of inheritance. your mental model is flawed here as you are conflating an instance with a subclass.

yeahhhhhhh, I see. It's been a while since I've done any OOP stuff. Woops. Thanks for clarifying that. And here I am saying "ohh that **** was so easy," lol.

Makes me nervous about my other answers:

1. For, while, do while

2. Call by value: You pass a copy of the value into the function. Any and all changes are kept local. Call by reference: you pass the memory location of the value. Changes made inside of the function affect the value outside of the function

those are correct. 1 is just a totally bizarre question. it would make me suspect of the company hiring you more than anything else.

Yeah I did pick up a slightly suspicious vibe. Either way, I'm not going to accept the position because it involves relocating every 2-5 years. Of course that wasn't mentioned until the end of the interview.

My old company asked "Does Java do variable passing by reference or by value?"

Hilarious arguments came out of that. It's actually a great meta-interviewing question. Before someone should be allowed to interview they should be asked what a good answer to the above is. Anyone that feels strongly about one or the other answer - without listening to the explanation given - shouldn't be an interviewer.

agreed on all this. refactor it as "name some loop constructs and give an example of what they're good for" and it's a fine question.

you (potentially/arguably) left off foreach, goto, and duff's device.

The way it was explained to me was that they have their software and when a new client is going to start using it, you get moved to that location and do a lot of discussing about what their specific needs are and work on customizing/tailoring the software for that purpose. Rinse and repeat.
