Hobbyists Unlimited: Fill & Download for Free

Some other development tools for developing iOS apps are Revrun LiveCode, Ansca Corona and Adobe Flash Professional 5. These development tools all have easier learning curves than Apple's SDK.These alternative development environments still require that you be an Apple iOS Registered Developer in order to run apps created with their tools on iOS devices. (This is Apple's requirement.) It costs $99 per year to be an iOS Registered Developer, and there are other requirements, such as you must be an adult.Of particular note for hobbyists is Ansca Corona which allows use of their development tools for "free unlimited trial" until you decide to publish an app on the App Store, at that point you need to purchase a license. That could be a nice setup for a hobbyist primarily wanting to experiment. If and when you decide you want to publish apps a royalty-free licenses for Corona currently cost $199/year for iOS.

I’m going to go a little different from the other answers you’ve gotten, and address it from the other end of things:”….but the same plants can grow in the wild with unlimited soil?”At the meetings of the cactus and succulent club I belong to, we’ve been lucky enough to have speakers who have given presentations, complete with slides, of trips they’ve taken to observe cactus and succulent plants growing in their natural environment (“the wild”).When you see how many of these plants grow in their natural environment, they’re not growing in “unlimited soil.” Most of them are growing in “soil” that’s more like rocks and pebbles with a little dirt mixed in, or in cracks and crevices on very steep, rocky slopes, or in environments where there’s a lot of wind— a LOT of wind— and whatever soil the plant grows in is very restricted in a small area protected from the wind by rock outcropping or other features.Cacti and succulents didn’t evolve to grow in “unlimited soil.” They evolved to grow under conditions where in many cases you wouldn’t think there’s enough soil for any plant to grow. They don’t grow like propagated cacti:So forget the “grow in the wild with unlimited soil” hypothesis. That isn’t at all descriptive of the real natural environment for most desert cacti and succulents (there are tropical cacti and succulents, and that’s a different kettle of fish completely).With regard to the “correct” size pot for a cactus or succulent, there are a number of variables that need to be considered.Drainage, drainage, drainage is the most important factor in keeping cacti and succulents healthy; and most of the hobbyists I know of find that commercially-available clay, ceramic or stoneware pots just don’t have large enough drainage holes. Many of them have special drill bits that they use to enlarge holes or to drill additional holes.Most hobbyists that I know of also do not use commercial cactus potting soil, the kind you can buy at Home Depot or Armstrong Garden Centers, without some serious alterations of their own to enhance drainage.Most hobbyists I know of do something like 50 percent pumice or perlite to 50 percent potting soil; some do 1/3 coarse sand, 1/3 potting soil, and 1/3 pumice or perlite. (Pumice is preferred, but it can be hard to find garden supply places that carry it.) I know some people who go as far as 75 percent pumice or perlite and 25 percent potting mix.To some extent, the size of the pot you use depends on what you intend to do with the plant. People who grow cacti and succulents to show at hobbyist shows are extremely picky about the size of the pot they use. Appropriate pot size is one of the judging criteria.Another factor to consider, and I didn’t see this addressed by any other answers, is how many plants you’re growing in the pot.If you’re growing more than one cactus or succulent in a pot, you’re going to need a bigger pot.You also need to give some consideration to the growth habit of the cactus or succulent you’re potting. A number of species of cacti want to form clumps over time; the parent plant grows to a certain size, and then it starts putting out “pups” or “offsets” that in their turn grow big and produce offsets of their own. If your goal is to show the cactus as a clump, you want to encourage the offsets, and that means a pot with enough room to allow them to grow. (Repotting a clump of cacti is a pain in the patootie.)The cactus in the foreground in the pot below started with a single parent plant. This autumn I put it in a pot on its own.I hope this helps answer your question.Edit: just took a picture of that clump of cacti now:

Here are some things we did in the 1970s when I was a freak. That’s what we called ourselves, not hippies.Drove cabs. Berkeley had its Taxi Unlimited, with the motto “No shirt, No Shoes, No Tie.”Repaired musical instruments. My father, although he was an old beatnik rather than a freak or hippie, lived among hippies and at the Placitas commune. He worked on electric guitars, adjusted truss rods, levelled the frets, etc.Programmed computers. The early hobbyist computers attracted a do-it-yourself crowd of longhairs.Sold drugs. Generally this meant marijuana.Worked in coffee houses. Owned coffee houses.Waited tables.Cooked in restaurants. This often meant wearing a hairnet to meet health department regulations.Performed music. Gave music lessons.Ran small businesses, like bookstores and record stores.Read the tarot for money.Did translation work—those who travelled a lot often spoke and read several languages.Worked at carnivals and state fairs.Were photographers and filmmakers.Were teachers and college professors.Wrote and illustrated and sold books of poetry and underground comix.Farmed.Went to sea as merchant seamen.Roadies and stage crew for rock and folk concerts.Tuned pianos.Were massage therapists and Rolfers.Were rock n roll promoters.Had fruit orchards.
