imagemagick can invert colors of jpeg so: mogrify -negate image.jpg however, that's not lossless. intuition says color inversion should doable in lossless fashion, @ least grayscale images, know hardly jpeg. hence questions: is lossless jpeg grayscale inversion possible in theory? if so, libjpeg or other software out there able it? jpeg encodes images series of entropy coded deltas across mcus (minimum coded units - 8x8 blocks of dct values) , entropy coded quantized dct coefficients within each mcu. inverting pixel values (even if grayscale) involve decoding entropy coded bits, modifying values , re-encoding them since can't "invert" entropy coded dct values. there isn't 1 one matching of entropy coded lengths each value because bits encoded based on statistical probability , magnitude/sign of quantized values. other problem coded dct values exist in frequency domain. i'm not mathematician, can't sure if there simple way invert spat...

i selecting id cannot equal 0, nor can value (null) . wrote: where id not null (+) , id not in ('0') i got 2 errors error(9,5): pl/sql: sql statement ignored error(38,119): pl/sql: ora-00933: sql command not ended change to: where id not null (+) , id not ('0') same errors occurred. should write where clause? you can simplify condition just: where id != 0 because comparisions null (using both = or != operators) evaluates null (which treated in sql "false" in conditions), therefore null != 0 evaluates false , can skip part in condition whre id != 0 , id not null braiam's answer where nvl(id,0)<>0 , although correct, prevent database using index on id column, , have bad impact on performce.

i have element line-height set calc() : line-height: calc(3rem / 2); demo: http://codepen.io/ghodmode/pen/vlxzzd it works fine in chrome, firefox's developer tools says it's invalid property value. i'm sure i'm missing should obvious. just reference: https://developer.mozilla.org/en/docs/web/css/calc http://caniuse.com/#search=calc thank you. this known issue. firefox not support calc() values on properties accept either lengths or numbers, of line-height 1 such property. see bug 594933 . since 3rem / 2 1.5rem can hardcode amount instead workaround.

last year, used code below convert character string datetime , worked, unexpected results after running strptime . data <- structure(list(time = c("12:00 am", "1:00 am", "2:00 am", "3:00 am", "4:00 am", "5:00 am", "6:00 am", "7:00 am", "8:00 am", "9:00 am", "10:00 am", "11:00 am")), .names = "time", class = "data.frame", row.names = c(na, -12l)) why give me expected results strptime: strptime(data$time[1:10], format="%l:%m %p") # [1] "2013-03-01 00:00:00" "2013-03-01 01:00:00" "2013-03-01 02:00:00" # [4] "2013-03-01 03:00:00" "2013-03-01 04:00:00" "2013-03-01 05:00:00" # [7] "2013-03-01 06:00:00" "2013-03-01 07:00:00" "2013-03-01 08:00:00" # [10] "2013-03-01 09:00:00" but when try replace existing data new data forma...

with following code: case "getsites": case "sitesetup": messagebox.show("help! suffering air-conditioned nightmare!!!"); // ... will messagebox.show executed either switch value "getsites" or "sitesetup" ? or only if switch value "sitesetup" ? since "getsites" has no break, i'm thinking yes, not sure. update i guess way should have worded question as: are these 2 code fragments semantically equivalent? fragment 1 case 0: case 1: // bla bla bla; break; fragment 2(pseudo code) case 0, 1: // bla bla bla; break; what describing having 2 labels same case. c# allow this. cannot, however, fall through next case statement in same way c allows, is, label cannot have code, fall through next case statement. forbidden , cause compilation error.

suppose have dataset following df = pd.dataframe({'x1':['a','a','b','b'], 'x2':[true, true, true, false], 'x3':[1,1,1,1]}) df x1 x2 x3 0 true 1 1 true 1 2 b true 1 3 b false 1 i want perform groupby-aggregate operation group multiple columns , apply multiple functions 1 column. furthermore, don't want multi-indexed, multi-level table. accomplish this, it's taking me 3 lines of code seems excessive. for example bg = df.groupby(['x1', 'x2']).agg({'x3': {'my_sum':np.sum, 'my_mean':np.mean}}) bg.columns = bg.columns.droplevel(0) bg.reset_index() is there better way? not gripe, i'm coming r/data.table background nice one-liner like df[, list(my_sum=sum(x3), my_mean=mean(x3)), by=list(x1, x2)] you use @happy01 answer instead of as_index=false add reset_index end: in [1331]: df.groupby(['x1', 'x2'])['x3'].a...

the logout feature in rails application appears working when run app locally using localhost:3000 ; however, when logout on production server directing me http://example.com/users/logout , when go http://example.com still logged in. i pushed changes git repo , both dev / prod both running same source code. not sure why prod box isn't logging user out when click logout link. development.rb rails.application.configure # settings specified here take precedence on in config/application.rb. # in development environment application's code reloaded on # every request. slows down response time perfect development # since don't have restart web server when make code changes. config.cache_classes = false # not eager load code on boot. config.eager_load = false # show full error reports , disable caching. config.consider_all_requests_local = true config.action_controller.perform_caching = false # don't care if mailer can't send. co...

i'm confused behaviour of type conversion when constructing structured/recarray: this simple example takes in numerical fields defines type string: data = [(1.0, 2), (3.0, 4)] np.array(data, dtype=[('x', str), ('y', int)]) which produces: array([('', 2), ('', 4)], dtype=[('x', 's'), ('y', '<i8')]) so values converted empty strings not expect from: str(1.0) which produces string '1.0' . what's causing behaviour? you need specify string width, e.g. 'a3': >>> np.array([(1.0, 2),(3.0,4)],dtype=[('x','a3'),('y',int)]) array([('1.0', 2), ('3.0', 4)], dtype=[('x', 's3'), ('y', '<i4')]) just using str means string field of 0 bytes - of course small hold string rendition of float.

are there atomic operations derbyjs? from documentation seems there no operations mongodb addtoset ? how 1 implement this? there model.setnull , model.setdiff operations. there no equivalent addtoset .
