i'm wondering, if there axure rp alternative better price. used other apps, ended axure rp because of 2 fundamental advantages: it's not wireframe tool, lets me prototype whole web/app functional demonstrations it generates/exports prototype , customers can try personaly (it's html site , upload server , clients email link follow) so, there else axure rp meeting 2 criteria better price? apps i've seen fail in second condition. you can use moqups.com , it's web app. lets make prototypes linked pages , more . lets share design through url on site.

most of use httpclient , connection pooling connection gets reused multiple client thread. now if 1 client gets read-timeout, releases connection pool may used other threads. but curious know happens @ server side. server still processing request , may try write data write_buffer. since connection not closed, how write_buffer gets cleared before other request comes in using same tcp connection. what happens server worker thread , write_buffer when reader gets timeout. does reader(httpclient) interrupt or send ack server when gets timeout.

i have started learn magento's , oberver architecture. had been thinking if possible prevent magento store loading js , css files in normal way , instead making load locally stored js , css files. the point of idea have control on third party resource loading and, ideally, the possibility defer js/css resources. for example, can merge , defer or change js files in page.xml layout normal, want make module see js file loaded , make load js file from, say, var/resources . third party resources, e.g. trustpilot js, found, intercepted , pointed locally downloaded version of files var/resources . and complete cake - ability specify insert element on page, before tag. so can (reasonably?) done magento module? how should go doing that?

i have been struggling in creating decent looking scatterplot in r. wouldn't think difficult. after research, seemed me ggplot have been choice allowing plenty of formatting. however, i'm struggling in understanding how works. i'd create scatterplot of 2 data series, displaying points 2 different colours, , perhaps different shapes, , legend series names. here attempt, based on this : year1 <- mpg[which(mpg$year==1999),] year2 <- mpg[which(mpg$year==2008),] ggplot() + geom_point(data = year1, aes(x=cty,y=hwy,color="yellow")) + geom_point(data = year2, aes(x=cty,y=hwy,color="green")) + xlab('cty') + ylab('hwy') now, looks ok, non-matching colors (unless became color-blind). why that? also, how can add series names , change symbol shapes? don't build 2 different dataframes: df <- mpg[which(mpg$year%in%c(1999,2008)),] df$year<-as.factor(df$year) ggplot() + geom_point(data = df, aes(x=cty,y=

i running predictive model using decision forest regression. there 1 categorical column called "type" has 2 levels "ab" , "cd". data available has more records "ab" compared "cd" (75:25). , therefore model biased more towards "ab" , hence predicts output better "ab". how can reduce biasing effect? i thinking of converting "type" numeric (0,1) , calculating weighted mean, can please elaborate approach or suggest other approaches, new predictive modeling. thanks!

i have csv file looks ~5m rows: 11/8/2016 2.495418222 2.501995109 2.488331492 2.504259694 11/8/2016 2.495759632 1.213707641 2.137418322 2.501118589 11/8/2016 2.495565218 3.050992103 0.870950956 2.500971719 11/8/2016 2.494934557 2.500041484 2.489212707 2.455110626 i trying find both max , min values of 10000-row sample, , iterate until end of data. (finding trend of multiple max , mins). code grabs value every 10000 rows instead of require above. lcd = pan.read_csv('daq_test_2016-08-11.csv',usecols=[0,2,3,4,5],skiprows=[0,1,2],na_filter=false) lcd = np.array(lcd) tslen2 = len(lcd[:,0]) rph2 = 57600 sfr2 = tslen2/((tslen2/rph2)*(2)) currentdata = (lcd[0::sfr2]) you can try this: lcd = pan.read_csv('daq_test_2016-08-11.csv',usecols=[0,2,3,4,5],skiprows=[0,1,2],na_filter=false) # group every 10,000 rows groups = lcd.groupby(pd.cut(lcd.index, range(0,len(lcd), 10000))) groups.min() groups.max()

i trying export turtle variable value <= item 0 of patch list. these values interested in recording, having trouble getting code right that. i've tried below: file-print turtles [turtlevariable <= item 0 patchlist] i know that's not right getting number of turtles, , not turtle variable value. run model 1000 times , unsure how create code file manageable manipulate in excel. i'm pretty sure there simple answer, can't figure out! appreciated. you have multiple questions here. need post each question separately. take on following: how can list of values turtlevariable , values < item 0 patchlist . globals [patchlist] turtles-own [tvar] patches-own [pvar] test ca ask patches [set pvar random-float 1.0] set patchlist [pvar] of patches let _p00 item 0 patchlist ;;compute once crt 100 ask turtles [set tvar random-float 1.0] let _tset (turtles [tvar < _p00]) let _tvals [tvar] of _tset print _tvals end you can file-pri

there way use if statement on eloquent? i have 1 table called 'invoices' .. invoices(invoiceid,debt,status) status represents if invoice payed or not, , debt debt on invoice. i'm asking if there quick way update status in such way when make payment.. if invoice.debt = 0 invoice.status = 0 else invoice.status = 1 i'm using laravel 5.3. thank you! it seems you're going in right way, you can as: $invoice = invoice::find(1); $status = ($invoice->debt == 0) ? 0 : 1; $invoice->status = $status; $invoice->save(); hope helps!
