dealing with Encoding::UndefinedConversionError: "\xA2" from ASCII-8BIT to UTF-8
I''m 99% certain that this is what''s being discussed in https://github.com/tenderlove/mechanize/issues/168 But I''m not sure what the remedy is. My production app is running on Heroku, so I need a fix that I can push there. Can someone post instructions that this neophyte can follow? (I gather I''m supposed to fork and add the current master version from

Using rack.hijack with ActionController::Live
Pinging @tenderlove Some questions on how best to move forward with this: 1.) AC::Live is making use of the stream object on ActionDispatch::Response. Should the rack.hijack_io object be used instead of this in AC::Live or should ActionDispatch::Response be changed to use rack.hijack_io? 2.) What do you think about changing AC::Live to work with adapters? I suspect the primary use case for

WWDC Puppeteer lunch
Reminder for Mac Puppeteers going to WWDC How about we meet for lunch at noon on Tuesday. Let''s try to get the table closet to the Odwalla refrigerator, just for reference. We can get more specific on this list on the 8th after we verify the set up. I might even get there a little earlier and put down "reserved" tags. --- Thank you, Allan Marcus Solutions Architect Central

suprising behaviour of tryCatch()
Because `<-` and `=` do different things (and I am one of the old fossils that wish they had not been confounded). `fun(x <- expr)` Assigns the value of `expr` to the variable `x` in the frame/environment that `fun` is called from. `fun(x = expr)` Assigns the value of `expr`to the variable `x` in the frame/environment created for and used by `fun` subject to the rules of argument matching.

suprising behaviour of tryCatch()
Hello, I run a fisher.test() in a loop, with the issue that some of the data will not be useable. To protect the loop I used tryCatch but: sexsnp = rep(NA, 1750) for(i in 1:1750){tryCatch(sexsnp[i] = fisher.test(table(data[,3], data[,i + 38]))$p, error = function(e) print(NA))} Error: unexpected '=' in "for(i in 1:1750){tryCatch(sexsnp[i] =" But this works: for(i in

Float::INFINITY ranges in where() clause
This seems like such an obvious idea that I''m having trouble believing I''m the first to think of it. Why not take ranges containing Float::INFINITY and translate them to the appropriate greater than or less than comparisons? Example: class Person scope :voters, -> { where(born_on: (-Float::INFINITY..18.years.ago)) } end This would generate something along the lines of

html parser / assertions in a model
I am using http.get in a model to parse html code returned from a Oracle server. My first try was to use assertions (assert and assert_select) to test and parse the html code. But I have problems including the methods in the model. Have tried both "include" and copy/paste to get assertion methods into my model. Works as a model, but I get load errors when I am using the model from a

Database connection parameters are tied to the filesystem
HI Guys, I recently tried VERY hard to override the database configuration bassed on ENV vars or actual API calls. This task is almost next to impossible. I know that the database.yml file is parsed as ERB but that is sane for simple ENV replacement if you want to actually change which database adaptor it is (requires extra config/params) it becomes messy. I found

LIbrary to maintain manage browser sessions from command line
I have to update 80 pages'' compliance terms on our clients existing CMS system. I can''t do this on the back end, and it''s a tedious task I''m looking to automate. These are all in an admin panel, so I am trying to find a library that could at least maintain a session and simulate browser interaction from the command line. Any leads would be helpful! Thanks!

[PATCH] Don't exist from cleaner_kthread and transaction_kthread until kthread_should_stop is true
upstream commit 2ad49887150894b9ed6a87a76b409adceee6b074 Motivated from the commit, I found that cleaner_kthread() and transaction_kthread() can result similar error since these two function can exit even though kthread_should_stop() is not true. In order to resolve the bug, break statements are changed into continue statements in order to wait until kthread_should_stop() becomes true. ---

Combined Marimekko/heatmap
Hi all, I'm trying to figure out a way to create a data graphic that I haven't ever seen an example of before, but hopefully there's an R package out there for it. The idea is to essentially create a heatmap, but to allow each column and/or row to be a different width, rather than having uniform column and row height. This is sort of like a Marimekko chart in appearance, except that

how does the bootup screen move the cursor around?
While rebooting my computer after installing the new kernel a few minutes ago, I got to wondering about how the initial bootup screen (after grub, before rhgb) is constructed. The "Loading kernel blah blah blah" lines start at the top of the screen and proceed to scroll down as one would expect. But "kernel alive" shows up at the bottom of the screen and then more write-up is
