can 1 please me on this. i using cypher query nodes having relationship either 'hive' or 'hadoop' , able nodes. but when try nodes having relationship both 'hive' , 'hadoop' not able nodes. this query using start n=node(*) match (n)-[r]-() type(r)="hadoop" , type(r)="hive" return n,count(n); this query returns 0 rows. is query wrong or need other way. thanks in advance. gouse this should it: start n=node(*) match ()-[:hadoop]-(n)-[:hive]-() return n,count(n)

i have been trying question while code keep running without returning implement following function fahrenheit return fahrenheit equivalent of celsius temperature.f = 9/5c + 32 : use function write program prints chart showing fahrenheit equivalents of celsius temperatures 0–100 degrees. use 1 position of precision right of decimal point results. print outputs in neat tabular format minimizes number of lines of output while remaining readable here code def temp_check(c): f = 0 c in range(0, 101): f = (9/5) * c +32 print "celsius %3.1f c" %"fahriant f" print " %3.1f c" % f(c, f) you need call temp_check function adding line after (no indentation): temp_check(none) the value passed temp_check doesn't matter here, since you're overwriting anyway.

i have latest version of crystal report (2012 ? believe) , inserting crosstab in report header summary. printing fine , correctly except page number in page footer (actual whole page footer page number defined in) not print. if crosstab has lot of data , runs on multiple pages, page footer not print either until report header section has finished. for example, if cross tab section run on 2 pages, footer print starting page 3 , onward. page numbering correct footer not print on report header only. there way make crystal report print out footer in report header section? think can put cross tab in report header section want print once. putting in page header make print each time there new page.

i'm new r , need keep dataset contains each observation (let's - user) list of classes (let's events). example - each user_id hold list of events, every event class contains fields: name, time, type. my question - optimal way hold such data in r? have several millions of such observations need hold in optimal manner (in terms of space). in addition, after decide how hold it, need create within python, original data in python dict. best way it? thanks! you can save dict .csv using csv module python. mydict = {"a":1, "b":2, "c":3} open("test.csv", "wb") myfile: w = csv.writer(myfile) w.writerows(mydict.items()) then load r read.csv . of course, depending on python dict looks like, may need more post processing, without reproducible example it's hard be.

my colleague told me ejb shoudln't contain method implemetation, must delegate method calls "helper" classes, i.e. ejb methods should this: public string bsuinessmethod1() { return helper.bsuinessmethod1() } public void bsuinessmethod2() { helper.bsuinessmethod2() } and reason delegate methods above, have less coupled code (for example when want reuse methods of "helper" class not in ejb context). told business methods shouldn't know java ee. (correct me if above statement wrong, , please note don't use jpa transactions, use framework dealing data persistence) so if above statement correct, "helper" classes should have same methods ejb. can reuse ejb interface helper class (i.e. make helper class implement same interface ejb)? not bad architectural point of view? i dont think delegate method calls "helper" classes , means keep ejb method 1 liner calls helper class(es). intent of delegating implemen...

i came across question in book 'invitation discrete mathematics' matousek , nesetril. new these kinds of problems. approached problem in way: 2 numbers selected among 501 numbers consist of divisor , dividend. number greater 500 cannot divisor. need @ least 1 number in range 1-500 inclusive. , in fact number in range given fact need select 501 numbers 1000 numbers. i divided selection of 501 numbers following cases: case 1- select numbers between 501-1000 inclusive , number between 1-500 inclusive. in case, statement provable because numbers between 1-500 have @ least 1 dividend in range 501-1000 , whole range selected. case 2- select numbers between 1-500 inclusive , 1 number between 501-1000 inclusive. in case also, statement provable there many pairs in range 1-500 serve divisors , dividends each other. case 3- select numbers in range 1-500 , numbers in range 501-1000. having trouble proving number in range 1-500,there dividend selected. this question may of...
