I've been reading comments like below from the Unofficial Course Survey on G+, from the recent Spring 15 students who took the course

1/ This is the most disorganized course I have taken in the OMSCS program. There is no professor involved with the course at this point, so it is entirely run by a group of TAs who do their best to make everything work but don't have the resources, time, or authority to fix the aspects of the course that are broken.

2/ Coming off of a course where the professor was heavily engaged (CS6300 w/ Alex Orso) this course is a disappointment. AFAIK there is no professor supervising the TAs and there has been some snark on Piazza between the students and the TAs

I've populated data frame dfa from a table using RODBC. It has a column x having type raw[1:4] which is stored as a byte(4) field in the table. There are other integer and factor columns (only one (y) is included here for simplicity). I'm melting the frame and trying a facet_wrap plot on the raw variable when ggplot2 is complaining.

str(dfa)
'data.frame':	4750 obs. of  2 variables:
 $ x:List of 4750
  ..$ : raw  00 00 20 00
  ..$ : raw  00 00 20 00
  ..$ : raw  00 00 20 00
  ..$ : raw  00 00 20 00

 $ y:List of 4750
  ..$ : int 0
  ..$ : int 0
  ..$ : int 0
  ..$ : int 0

meltdfa <- melt(dfa, id.vars="x", measure.vars="y")

Tried replacing the LCD of my Macbook Pro 13" (mid 2010). Ended up burning the LVDS socket (to which the display cable goes). I might have to replace the socket which might need soldering the motherboard.

Any reliable place where they can do that? Someone with similar experience? The "official" apple repair shops didn't help much. Since they don't do repairs they just do replacements.

Also I found few shops in Ameerpet/Maitrivanam that do Apple repairs. Should I trust them?

Found below exact same issue on my Macbook Pro 13" (mid 2010, A1278)

I ordered and installed a new LCD (from ifixit.com) following the instructions manual. However the new screen did not work on the first attempt. Suspecting a faulty part, I re-installed my original screen to confirm. This time however I smelled something burning from the LVDS connector's end towards the logic board. I immediately disconnected the battery and everything stopped. I see the plastic on the clip/hook on the connector little burnt. Also there is tiny spot on the socket. I immediately disconnected the cable fr
