i think laravel solves problem well, extend question little bit. is possible in laravel show how many users logged in, in real time? like if 10 users logged counter should show 10 users logged in. shown ten users , in real time. so if users logs out, counter should decrease. the approach used after attempting login, can increment counter of 1 of column in db. can use table, logged in table. when users logged out, decrement counter deleting auth::id of user , count reduced. but want try in real time, how possible laravel itself?? you can use event broadcasting features of laravel 5 in real-time. every time user log in, need broadcast event. can follow tutorial: http://www.sitepoint.com/real-time-apps-laravel-5-1-event-broadcasting/ then on client side, need use javascript listen event.

my friend programming in c++ on 64-bit windows 7 pc , came crazy idea save little bit of memory: observed last 2 bits of memory addresses seemed 00, figured use bits other things , when memory address needed, use bit-mask set last 2 bits 0, either when writing or reading memory. reason why he's using last 2 bits needs work on 32-bit systems too. anyway, on windows 7 64-bit system got following blue screen error when running program: page_fault_in_non_paged_area could crazy memory savings idea causing this? i.e., can happen last 2 bits of memory address not 00, , he's accessing memory that's partly on 1 of memory pages, partly off page? in event, needs work on popular operating systems. question applies other operating systems well. if (in windows 7 64 bit, @ least) scheme guaranteed work (if coded properly), else causing unusual blue screen crash? your friend taking advantage of feature known tagged pointers . on windows, raymond chen has warning regardi

i calling api. depending on json data modyfing view controller in viewdidload() in order change views design display given data best way possible. what hide uiviews , set constraints .active = false changing of constraint eg: let nocbutton = nslayoutconstraint(item: alisttop, attribute: nslayoutattribute.centery, relatedby: nslayoutrelation.equal, toitem: alistbottom, attribute: nslayoutattribute.centery, multiplier: 1, constant: 0) view.addconstraint(nobidbutton) then before closing viewdidload() change/disable constraints call view.layoutifneeded() so question is, if change/disable constraints or hide uiview, should call view.layoutifneeded() afterwards? also, need call view.layoutifneeded() right after every change or can call once before closing viewdidload()? i dont errors in console either way, want make sure doing right way. noted functions updateconstraints layoutifneeded seems work, tho im not 100% sure difference thanks in advance, i c

i created ggplot linear geom_smooth have points, geom_point have different colour below , above linear smooth line. i know can add color point doing geom_point(aes(x, y, colour = z)) . problem how determine if point in plot below or above linear line. can ggplot2 or have create new column in data frame first? below sample code geom_smooth without different colours above , below line. any appreciated. library(ggplot2) df <- data.frame(x = rnorm(100), y = rnorm(100)) ggplot(df, aes(x,y)) + geom_point() + geom_smooth(method = "lm") i believe ggplot2 can't you. say, create new variable in df make colouring. can so, based on residuals of linear model. for example: library(ggplot2) set.seed(2015) df <- data.frame(x = rnorm(100), y = rnorm(100)) # fit linear regression l = lm(y ~ x, data = df) # make new group variable based on residuals df$group = na df$group[which(l$residuals >= 0)] = "abov

i have webpage set using node.js set behind nginx. everythings work fine, block direct public access css , js files in nginx config have this: location /style/ { deny all; } location /js/ { deny all; } it correctly block access - when view source on webpage , try navigate directly css or linked js files 403 error. however, prevents node/nginx being able correctly use files style/add functionality page what correct way prevent people directly accessing files, while still being able use them display page itself? there isn't way. either browser can access file , use in page, or can't access file @ all. you try using referer request header, you'll false negatives , people have downloaded page have access js anyway (either cache or script tab in browser's developer tools).

i have dataframe this: date 2015.1.1 10 2015.1.2 20 2015.1.3 30 2015.1.4 40 2015.1.5 50 2015.1.6 60 i need caculate std of top n rows, such as: date std 2015.1.1 10 std(10) 2015.1.2 20 std(10,20) 2015.1.3 30 std(10,20,30) 2015.1.4 40 std(10,20,30,40) 2015.1.5 50 std(10,20,30,40,50) 2015.1.6 60 std(10,20,30,40,50,60) pd.rolling_std used this, however, how change n dynamically? df[['a']].apply(lambda x:pd.rolling_std(x,n)) <class 'pandas.core.frame.dataframe'> index: 75 entries, 2015-04-16 2015-07-31 data columns (total 4 columns): 75 non-null float64 dtypes: float64(4) memory usage: 2.9+ kb it done calling apply on df so: in [29]: def func(x): return df.iloc[:x.name + 1][x.index].std() ​ df['std'] = df[['a']].apply(func, axis=1) df out[29]: date std 0 2015.1.1 10 nan 1 2015.1.2 20 7.071068 2 2015.1.3 30 10.000000 3 2015.1.4 40 12.909944 4 2015.1.5

i'm using jquery datatables plugin. sorting works fine, there way make 1 column stay same no matter sorting applied? for example, first column simple order numbers: 1, 2, 3, 4, 5... , when sort date, or else, first column stays in same order: 1, 2, 3..? is there way this? so, not trying disable sorting first column, make first column stay same when sorting applied columns. you can using orderfixed option defines ordering applied table. for example, sort first column in ascending order: $('#example').datatable( { "orderfixed": [ 0, 'asc' ] } );

i new caching thing, , want cache (just when app still open) arrays of data. can tell me how using nsmutabledictionnary ? thanks. nsmutabledictionary collection type allows store data via key / value pairs. key of pair search , value want retrieve. if have key named dob may expect value of "1-19-1989". if want cache right @ beginning of start in applicationdidfinishlaunchingwithoptions: in appdelegate file. go this... - (bool)application:(uiapplication *)application didfinishlaunchingwithoptions:(nsdictionary *)launchoptions { //// whatever data need nsstring *key = @"dob"; nsstring *value = @"1-19-89"; // place dictionary nsdictionary *dictionary = @{key: value}; // , nsmutabledictionary nsmutabledictionary *mutabledictionary = [nsmutabledictionary new]; [mutabledictionary setobject:value forkey:key]; return yes; } and @abhinav said, can either store nsuserdefaults small data , advise coredata large amounts of data.

i'm trying train random forest on accelerometer dataset. calculate features mean, sd, correlation between axes, area under curve , others. i'm ml noob. i'm trying understand 2 things: 1.if split dataset 1 person test , train , run rf prediction accuracy high (> 90%). however, if train rf data different people , predict, accuracy low (< 50%). why? how debug this? not sure i'm doing wrong. in above example, 90% accuracy, how many features "enough"? how data "enough"? i can furnish more details. dataset 10 people, large files of labelled data. have limited myself above features avoid lots of compute. most classifier overfits, when training on 1 person not generalizes well, may "memorize" dataset labels instead of capturing general rules of distribution:how each feature correlated other/how affect result/etc. maybe need more data, or more features. it's not easy question, generalization problem, there many th

i trying integrate ejabberd django authentication. following instructions on: https://github.com/ffalcinelli/django-ejabberd-bridge i have followed every step. i have defined path of script authentication {auth_method, external}. {extauth_program, "script.sh"}.

i have line segments , points stored in db. how query db in order retrieve points within distance of multiple line segments. purpose when user clicks on path (road), objects within distance path should highlighted. thank you. update: example... have path goes (0,0) (0, 10). program should find , highlight objects within x-distance of path. suppose x-distance "2"... then, program should highlight objects within rectangle (0,2)(10,-2). basically, same finding objects proximity line (not single point). it easy when line horizontal... don't know how solve cases, including line may slope. update: points stored in large database, cannot check each , every 1 of them proximity. i'm trying find way retrieve ones close enough without overlapping requests much... once retrieved, can refine search using method described in "distance between point , line segment". (i think!) thanks! this give distance point p line segment v,w. (based on questio
