[ "Converting a nested type into a monad transformer stack", "I’m having some trouble with one of the exercises in the Monad Transformers chapter from Haskell Programming From First Principles. Specifically, we are given a structure that looks like (const (Right (Just 1))) and are asked to finish the following: \n\nimport Control.Monad.Trans.Except\nimport Control.Monad.Trans.Maybe\nimport Control.Monad.Trans.Reader\n\nembedded :: MaybeT (ExceptT String (ReaderT () IO)) Int\nembedded = ??? (const (Right (Just 1)))\n\n\nI assume this means that we cannot change the nested structure, although the instructions are only to \"make it work.\"\n\nI've gone through a few routes before concluding that I am stuck. So far, from what I gather, monad transformers are most commonly created with a combination of lifts and dos — aside from the SO Q&As, Diehl summarizes pretty well here. \n\nI've also been working with the map<Monad>T variants from the transformers library to get some interesting / fun results, but I can't seem to find out how to solve the original problem. Any hints would be appreciated — however, if you post a solution, please use the spoiler markup (although I've never seen it used on anywhere other than in Puzzling)." ]

I also tried looking at the MSDN for WM_CTLCOLORSTATIC, since the name seems promising, but it doesnt seem like it triggers anything but background colors to be set.\n\nIs there another message I should be looking at, or am I approaching this the wrong way?

Therefore, we controlled for “D” in “A” and “B” within each condition “C”. Now, our long data set is twice as long as it was originally and a dummy coded within-subjects level-2 factor” control” indicated weather original “A” and “B” (control = 0)., or “A” and “B” without “D” (control = 1). A significant three-way interaction in the multilevel model would indicate that the covariance of “D” changed the interaction of AB after we controlled for “D”.\nIt is important to note that “A” and “B” (not controlled as well as controlled) were z-standardized variables. “C” was scaled between -2 and 2.\nNow to my problem:\nIf we controlled for D either in “A” or in “B”, but not in both, the estimators in the multi-level model make sense.\nControlled for D in A:\nShow table\n\nControlled for D in B:\nShow table\nBut if we controlled for D in both variables, I don’t understand the results.

My page works great, but it has me wondering:\n\nIf my page shares the same origin URI as every other web page hosted on S3, wouldn't this mean that another page would satisfy the same-origin policy and be allowed access to my page's access tokens?\n\nFor example, say a user just granted my app access to his Gmail account. Google sees an approved origin URI and sends back an access token.\n\nNow imagine some other page hosted on S3 had copied my app's Client ID (publicly stored as a variable in JS) and was repeatedly requesting for an access token from Google. Once my user grants that access to my page, won't the other page also receive the token from Google since it satisfies the same origin URI?\n\nI realize one solution to this potential problem is to host my web page on a domain that I have control over, but I'm curious if that is the only way." ]
