we using png/8 sprite on client's website. reporting image appearing distorted him , on other computers on company. here's how should look: http://i.imgur.com/wfv7rer.jpg and here print screen client sent us: http://i.imgur.com/swkdyku.jpg i have tried donloading , exporting again, uploading again. problem is: on our computers looks fine, it's hard test it. our client viewing in ie: 11 , google chrome: 41.0.272.118. has seen type of error before? it may device-pixel-ratio better 160dpi; that'd throw off css used spriting. if shows "1" , different value them, i'd dig farther on one. test hitting site iphone or newer android device; have >1.0 pixel ratios. http://www.devicepixelratio.com/ edit: show across-browsers on end, it's tied hardware, , not ie11.

i creating plot shows confidence intervals of 2 models each factor. if factors 'a', 'b', 'c', have 6 confidence intervals ci1.a, ci2.a, ci1.b, ci2.b, ci1.c, ci2.c. using simple forest plot want y-axis labels a, b, c, in middle of ci1.a , ci2.a. how can rearrange tick marks make them appear in middle of 2 factors? here toy example. have 49 factors need way able read of labels. factors <- c('a1', 'a2', 'b1', 'b2', 'c1', 'c2') y <- c(1:6) yhi <- y + .5 ylo <- y - .5 df <- data.frame(factors = factors, y = y, yhi =yhi, ylo = ylo) ggplot(df, aes(x=factors, y=y, ymin=ylo, ymax=yhi)) + geom_linerange() + coord_flip() i think best bet change data frame factor , model separate columns. that way, ticks automatically come out way want them. default, geom_linerange() position lineranges 2 different models on top of each other, can change position=position_dodge(width=...

you remember undergrad lectures in algorithms it's handy have concept of nil , can assigned or compared with. (by way never did undergrad in computer science.) in python can use none ; in scala there nothing (which subobject of if i'm understanding correctly). question is, how can have nil in c++? below thoughts. we define singleton object using singleton design pattern , current impression of wince @ thought of that. or define global or static. my problem in either of these cases, can't think of way of being able assign variable of type nil , or being able compare object of type nil . python's none useful because python dynamically typed; scala's nothing (not confused scala nil , means empty list) solves elegantly because nothing subobject of everything. there elegant way of having nil in c++? no, there no such thing universal nil value in c++. verbatim, c++ types unrelated , not share common values. you can achieve some form of shareab...
