Errata for The dRuby Book

#48975: My "r = DRbObject.new_with_uri('druby://localhost:12345')" call hung, but using a --noreadline option to irb didn't fix it (and I didn't need the option for the first example, so I think I'm OK without it).

I fixed the hang. After starting the server by calling:
s = DRb.start_service('druby://localhost:12345', front)

I did a:
s.thread.join

After doing this, the hanging client returned and the example worked fine.

I am running Ruby 1.9.2p290 on OSX 10.7.3--Stephen Morss

#49013: The figure 36 description is reversed. It should say down is equivalent to take and up is equivalent to write. Text currently says:

Figure 36—The implementation of a semaphore using TupleSpace. The down method is equivalent to write, and the up method is equivalent to take.

#50320: I am an Avon rep don't know alot about selling mark elveusiclxy.I do know as a Mark rep you get a 40%/ 25% discount on what you sell. The 40% is on makeup, fragrance and skincare type items and the 25 % is on things like shoes, purses, clothing. Avon/Mark do not make those items and can't give as big a discount on them as they do on the items that they do manufacture. So the more makeup, fragrance and skin care you sell the more money you will earn.I believe when you submit an order they do supply some magalogs free of charge. How many may be based on the size of the order. If you needed more than that you would have to order and pay for them. You have to pay for samples, if you want to give them out. I wouldnt buy too many to have on hand, maybe just a few. If someone wants a sample of something you don't have, you can get it with your next order. You need to pay for the order when you submit it so you'll need to collect the money in advance. That's all I can think of. Hope it helps--ktvmioucfhUmfakJt

#50330: I don't know how nature relaly works but I am getting to understand the reward system of being passionate about things like what you write. I am from Zimbabwe and I went back home to meet old friends amongst them singers, actors, lawyers etc and I found my self being the main speaker in most meetings about how as a person everyone should treat themselves as a brand. It came from the top of my head. That the most successful brand in the world is me the being, everything else can only act in symbiosis of what I perceive my self to be. And today I found this site and you book through an article you wrote for iol.co.za. I am so happy to actually know there is someone here in Africa, as matter of fact who has committed himself to this silent be necessary ingredient to self success. I am not much just a graphic designer who has a passion for expressionism so speak and a self tutored motivational speaker. I like your work. Thank you.--qEOAmwQJCNPuMm
