Reading and Writing Sequencefile using Hadoop 2.0 Apis -

i looking example using new api read , write sequence files. effectively need know how use these functions createwriter(configuration conf, org.apache.hadoop.io.sequencefile.writer.option... opts) the old definition not working me: sequencefile.createwriter( fs, conf, path, key.getclass(), value.getclass()); similarly need know code reading sequence file, follwoing deprecated: sequencefile.reader(fs, path, conf); here way use same - string uri = args[0]; configuration conf = new configuration(); path path = new path( uri); intwritable key = new intwritable(); text value = new text(); compressioncodec codec = new gzipcodec(); sequencefile.writer writer = null; option optpath = sequencefile.writer.file(path); option optkey = sequencefile.writer.keyclass(key.getclass()); option optval = sequencefile.writer.valueclass(value.getclass()); option optcom = sequencefile.writer.compression(compressiontype.record, codec);

sql - Update multiple columns on a row with a single select in sqlite -

in sqlite need update row counts of related table. the query below want walks table multiple times counts: update overallcounts set total = (count(*) widgets joinid=1234), totalc = (count(*) widgets joinid=1234 , source=0), totall = (count(*) widgets joinid=1234 , source=2), iic = (select case when count(*)>0 1 else 0 end widgets joinid=1234 , widgets.source=0), il = (select case when count(*)>0 1 else 0 end widgets joinid=1234 , widgets.source=2) id=1234 this query retrieves want need turn output update statement: select count(*) total, sum(case when source=0 1 else 0 end) totalc, sum(case when source=2 1 else 0 end) totall, case when source=0 1 else 0 end iic, case when source=2 1 else 0 end il widgets joinid=1234 sqlite not support joins in update queries. limitation of sqlite design. however, can still in sqlite using powerful insert or replace syntax. disadvantage of have entry in overallcounts (if did not have entry inserted). syntax

objective c - How to tell when UITableVIew has completed ReloadData? -

i trying scroll bottom of uitableview after done performing [self.tableview reloaddata] i had [self.tableview reloaddata] nsindexpath* indexpath = [nsindexpath indexpathforrow: ([self.tableview numberofrowsinsection:([self.tableview numberofsections]-1)]-1) insection: ([self.tableview numberofsections]-1)]; [self.tableview scrolltorowatindexpath:indexpath atscrollposition:uitableviewscrollpositionbottom animated:yes]; but read reloaddata asynchronous, scrolling doesn't happen since self.tableview , [self.tableview numberofsections] , [self.tableview numberofrowsinsection 0. thanks! what's weird using: [self.tableview reloaddata]; nslog(@"number of sections %d", [self.tableview numberofsections]); nslog(@"number of rows %d", [self.tableview numberofrowsinsection:([self.tableview numberofsections]-1)]-1); in console returns sections = 1, row = -1; when exact same nslogs in cellforrowatindexpath sections = 1 , row = 8; (8 right)

regex - Perl search and replace NOT working -

i trying replace string in file procedure seems removing string , not replacing want example perl -ne 'print unless s/serverip=${solid.host}/ads/;' needstobereplaced.prp > blah.txt will remove "serverip=${solid.host}" , leave line blank instead of printing "ads" in place i running in windows way. have no 3rd parameter in regex because want change first occurrence. have tried perl -pi -e 's/serverport=${solid.port}/ads/;' needstobereplaced.txt but permission errors editing in place no go you print line if substitution not successful. if want print always, not use unless : perl -pe "s/serverip=\${solid.host}/ads/;" needstobereplaced.prp > blah.txt you should escape dollar sign prevent interpretation perl. also note double quotes must used on ms windows.

actionscript 3 - How to determine primary swipe direction (using MultiTouch) in AS3? -

i'm trying implement simple swipe recognition on touch screen using as3. need know whether swipe left, right, top, or bottom. first question: easier using simple mouse_down , mouse_up, , calculate distance(s) moved? or easier using multitouch? i see code multitouch showing how implement swipe detection , getting direction thus: if (e.offsety == 1) { //user swiped towards bottom square_mc.y += 100; } if (e.offsety == -1) { //user swiped towards top square_mc.y -= 100; } if (e.offsetx == 1) { //user swiped towards right square_mc.x += 100; } if (e.offsetx == -1) { //user swiped towards left square_mc.x -= 100; } but if need resolve 1 direction (that left or up, right or bottom, etc), how do (and if offsetx , offsety true offsets, why checking +1 , -1 only? or function called during swipe? i'm trying 1 complete swipe). i'm thinking skipping multitouch might simpler, welcome fee

so pdf function calculates: fx = 0.3 if (0<=x<1) 0.1 if (1<=x<2) 0.25 if (2<=x<3) 0.15 if (3<=x<4) 0.2 if (4<=x<5) 0 otherwise , coding it: fx = function(x) { if ((0<=x) & (x<1)) 0.3 else if ((1<=x) & (x<2)) 0.1 else if ((2<=x) & (x<3)) 0.25 else if ((3<=x) & (x<4)) 0.15 else if ((4<=x) & (x<5)) 0.2 else 0 } how go plotting y=fx? i've tried: x <- runif(n,0,5) y <- fx(x) plot(x, y, type='1', xlim=c(0,5), ylim=c(0,5)) but error 'x' , 'y' have differing lengths? your problems comes down fact function isn't vectorized (it doesn't deal vector well). if use accepted solution previous question exactly same problem won't have issues eg # solution work , vectorized fx <- function(x) c(0, 0.3,0.1,0.25,0.15,0.20, 0)[findinterval(x, c(-inf, 0:5, inf))] x <- runif(n,0,5) plot(x, f

c++ - How to achieve O(1) erasure from a std::list -

the question recommended way use std::list achieve o(1) erasure of list items? usually, when choose doubly linked list, want able remove element list in o(1) time, , move different list in o(1) time. if element has own prev , next pointers, there no real trick getting job done. if list doubly linked circular list, removal doesn't require knowing list contains item. as per iterator invalidation rules , std::list iterators durable. so, seems me behavior desire when using std::list on own item stash iterator within class, , containing list. class item { typedef std::shared_ptr<item> ptr; struct ref { std::list<ptr>::iterator iter_; std::list<ptr> *list_; }; ref ref_; //... }; this has downside need create own decorated version of std::list knows update ref_ whenever item added list. can't think of way doesn't require embedded iterator, since not having 1 mean erasure incur o(n) find operation first. wha

MIPS: n choose k function -

so i'm writing calculator in mips , i'm trying write n choose k function. algorithm want use this: if want 5 choose 3 i'll have loop (5*4*3)/(3*2*1). suppose have multiply , divide functions, how implement in mips? right have this, isn't working @ all: calnchoosek: move $t1, $a0 move $t2, $a2 move $t3, $a0 # copies counter move $t4, $a2 loop_top: beq $t3, $t4, loop_bottom subi $t3, $t3, 1 move $a0, $t1 move $a2, $t3 jal multi move $t1, $v0 j loop_top loop_bottom: beq $t4, $zero, exit1 subi $t4, $t4, 1 move $a0, $t2 move $a2, $t4 jal multi move $t2, $v0 j loop_bottom exit1: move $a0, $t1 move $a2, $t2 jal divi i'm thinking logic totally flawed , might have start fresh. me? in loop_bottom , $t4 set 0 in last iteration. multiply $t2 0 , 0 denominator. divi calculating k*(n!-k!)/0 – divided zero!

this question has answer here: how reference existing class variables when defining them 3 answers can please explain why fail: class a: = 42 b = list(a + in range(10)) it fails because a isn't in namespace generator expression can see. this works python2 , python3. lambda default argument trick reference of a in namespace generator expression can see. >>> class a: ... = 42 ... b = (lambda a=a:list(a + in range(10)))() ... >>> a.b [42, 43, 44, 45, 46, 47, 48, 49, 50, 51] using list comprehension b clearer in opinion ... b = (lambda a=a:[a + in range(10)])()
