Mind Blowing Facts

i'm having problem xcode constraints. i'm laying out entire layout, selecting items , having xcode 'fill in missing constraints'. when run application in simulator, labels , textboxes not in right places. not visible @ (appear off screen) so there tips or tricks? should layout 1 item @ time, set constraints automatically move next? don't trust xcode , 'fill in missing constraints' feature. best option set constraints manually. after practice it's not hard. need indicate x , y coordinates , height/weight. i don't advice setting constraints automatically. causes more problems benefits. also check console log @ runtime. may happen there conflicts between constraints , need fix it. check out official guidlines

i'm using compare.linkage method in record linkage package in r compare similarity of 2 set of strings. default string comparing method jarowinkler 3 default weightages set @ 1/3, 1/3 , 1/3. i want overwrite default weightages 4/9, 4/9 , 1/9. how do that? in advance. the default script is: rpairs <- compare.linkage(stringset1, stringset2, strcmp = true, strcmpfun = jarowinkler) you have create own comparison function, compares 2 strings. in function can call jarowinkler . easiest way create closure : jw <- function(w_1, w_2, w_3) { function(str1, str2) { jarowinkler(str1, str2, w_1, w_2, w_3) } } this function pass weight parameters want use. function returns comparison function can use in compare.linkage call: rpairs <- compare.linkage(stringset1, stringset2, strcmp = true, strcmpfun = jw(4/9, 4/9, 1/9)) the jaro-winkler algorithm counts number of characters match (withing bandwidth) m . 2 strings john , johan there 4 characters mat...

i pulling large amount of data (700k lines) 1 database ( source database ), performing data manipulation, inserting/updating database ( lookup database ) altered data. the lookup database being accessed users regularly throughout day. performing select statements. updates lookup database occur hourly. size of data in source database increases, i'm noticing higher numbers of "lock wait timeout exceeded" errors when updating lookup database. assumption correct resulting select statements , update statements accessing same data? make sense larger number of updates occurring more hit data being accessed users. in attempts fix situation i've increased lock wait timeout 120 (up 60) has had little effect. one thought had update new table in lookup database, swap (in software users using) database queries go to. other ideas how might resolve issue? i'm not sure if it's relevant i'm using mysql , 2 databases on separate servers. thanks!

i want use seaborn jointgrid/jointplot. in middle add sns.regplot. on margins 2 sns.distplots or histograms. thats not problem, custmize 3 pplots differently , add different fiiting functions , labels 3 of them. but cant solve problem, how instances of plots if use predifined method: g = sns.jointgrid(x="total_bill", y="tip", data=tips) g = g.plot(sns.regplot, sns.distplot) to manually manipulated those. or other way around create 1 regplot , 2 distplot instances, define way wnat , add them jointgrid, in meaning of, unfortinaltely, these below methods don't exist or don't work way: g = sns.jointgrid(x="total_bill", y="tip", data=tips) g.add_joint(myreg) # great doesn't work g.ax_marg_x.add(mydist1) # invented code g.ax_marg_y.add(mydist2) # show you, way i'd solve issue can give me advice, how around issue? well, documentation has few examples . if want same distplot on both marginals:...

i have output program text like: ------------ action specified: getinfo gathering information... reported chip type: 2307 reported chip id: 98-de-94-93-76-50 reported firmware version: 1.08.10 ------------ but must save just, reported chip type: value "2307" in variable. how it's possible? you regex import re match = re.search('reported chip type:\s(?p<chip_type>\d+)', my_text) chiptype = int(match.group('chip_type')) >>> print chiptype 2307 in case though, it's simple enough use couple splits : chiptype = int(my_text.split('reported chip type:', 1)[-1].split('\n')[0].strip())

to differentiate data each database , in examples neo4j has movie db , northwind db, how know @ end sought of database/graphs we've. how these managed (database administration point of view). secondly if connect sqlserver client , can have list of database each database has own db objects. how can deal below points: to execute query on particular database or graph , in sqlserver can either use full qualified name under db context e.g select * amazon.dbo.people or "use amazon" , call store procedures,views,functions or whatever objects. neo4j not have concept of multiple databases in 1 neo4j instance. can run multiple databases setting multiple instances - on same machine. another option organize graph multiple distinct subgraphs.
