What's the typical workflow for this look like? That is, if you're making changes to the code live, and you're trying this and that in the REPL to fix things; once you get it working, how do you then get those changes out and then into your source code repository?

What? No. It's quite easy for teachers to locate a school that's looking for them. The state teacher's union usually has a website listing jobs and everyone just uses that one single website.

Just curious: Why was mzscheme chosen to implement Arc rather than some other Scheme implementation?

Originally we used Scheme48. I forget exactly why we switched. I vaguely recall some problem with threads. I think we chose PLT Scheme because it seemed like the default Scheme implementation.

Step 1: Around lunch time, in a very nonchalant way, stroll out to your car, set your watch/portable-alarm-clock/cell-phone-alarm-clock to wake you up near the end of your lunch break, tilt back the seat, and zzzzzzz.....

Step 2: After waking, splash cold water on face, then eat your lunch at you desk.

But wouldn't a large (and growing) population of frustrated young men serve to change this demographic trend? Or do you see a vicious cycle here?

Wrap a GUI around it and package the program as a single executable. I'd suggest $15. Asking for $20 seems like too much (to me), but I've been told that I have bad judgement in such matters. :)

Also, I agree with others that trying to sell a CLI version will probably go nowhere. In fact, it may stifle adoption after you switch to the GUI version (since prospective users might think "Oh, that's that terminal program, right? Yuck!").

And if there is other software that does what yours does, what is being charged for it?

The wife told me I can't spend any more time working on it, unless I can break even on web hosting, etc. So to clarify. I have to pay for web hosting, bandwidth, storage... as those things cost me money.

That's not what he asked, though.

Seriously? That's your hang up? The cheapest web hosts are about $5/month. It ought to be easy to figure out how to make $5 with craigslist, tipjoy, temp labor firms, a lemonade stand, a garage sale, or doing discount handyman services for friends and family.

I made my first $5 bill for helping my uncle take some stuff to the dump when I was about 8 years old. AND he bought me a coke, BONUS! And let me tell you, $5 was worth a whole lot more back then.

Yikes, you can sell nothing and break even. No, I actually sold an app for while, then took it down. People would still buy it occassionally, even though it was clearly stated that the app was discontinued.

?????????????? That's it?

Sign up for one of the millions of free blog/file hosts. Don't bother with a real domain name. Google pages seems nice.

if it is just the webhosting bill, you can certainly break even with adsense

I doubt that. It is not a webapp that the OP was asking about so the common pattern of usage would be download the software, use it, maybe come back and download an update. I don't think that adsense would be enough in this situation. I could be wrong though.

I've having a particularly bad time right now (big and manifold responsibilities, not enough time) and only getting 3-5 hours / night on weeknights. This has been going on for months now (with some regular 7-8 hour sleeping nights once in a while).

Results I've found: Mornings really suck. I'm putting on weight. I also feel terribly unhealthy. I'm not as sharp as I am at full power (though this is subjective and very hard to discern). I can fall asleep in minutes if given a place to lay down. Also, I get sick much more often than usual (which was hardly at all). Subjective opinion: it feels like I'm prematurely aging myself.

Trying to "make up" the sleep on weekends doesn't work for me. Oversleeping just leads to bad headaches.

When I do get a solid 8 hours I feel like Superman the next day.

I'm hoping that I'm not doing any long-term damage to myself, but there's really no way out right now. :( The current job ends very soon (2 weeks!), and then I'll be able to resume normal sleeping habits (7-8 hrs/night).

Ditto on putting on weight, ditto on the unpleasant effects of oversleeping to catch up, and ditto on not being sharp. The thing to keep in mind is that you're well beyond the point of diminishing returns. If you aren't achieving maximum output in somewhere between 6 and 10 working hours per day, then you're suffering from distractions -- something else is sucking up your productivity.

See my other post for my difficulty with undoing the habit of undersleeping. Even though I no longer experience any external pressure to undersleep, I still don't get enough sleep and suffer the consequences for it. It's hard to stop.

Pretty much my experiences too. I had a couple of years burning my candle at both ends and I felt like what you described.

Now, if I stay up late I invariably get bad eye inflammation - you can set a clock to it. It has been diagnosed by several doctors as an auto-immune reaction caused by the immune system failing.

Neglect sleep and your body will let you know, probably before your good sense should have.

Which do you prefer (and why), HtDP or SICP?

> As for developer availability - good luck to him finding good C programmers

Are you saying it's difficult in general to find good C devs? Because it would seem that's the case for C++, but not for C.

I'm not sure that's accurate. c++ is a large language. Finding developers who use the parts of c++ that you need to get the task done is easy (boost, qt, stl, wx, etc). Finding developers that know all of c++ is next to impossible. c++ is large because it can solve very large, very complex problems, but not every c++ application attempts to do this. c++ can be used in very simple ways too and many people use it in that fashion.
