i have 1 question timing of interrupt generation between code snippets... @ "example" code 1. ... 2. assign value global variable // 0/1 means invalid/valid 3. set h/w register via memory-mapped io method // 0 means completed @ "example" isr code a. ... b. if(global value valid && h/w register "0") count++; one thing note: after h/w register set, value 0 when "completion" ! my question is : if interrupt generated between 2 , 3 , count increased 1 because step 3 not done yet(value 0)... , if exchange 2 , 3 , possible count not increased 1 because hw register 0(after time, completed) global variable 0 ! my first idea is: possible 2 , 3 can "tied together" in way , interrupt not allowed generated until 3 done ? i use watcom c , test in dos... you can use either inline assembly, or call external function written in assembler, invoke x86 cli , sti instructions disabling , enabling interrupt

i writing code rapidly exploring trees robotic arm movement. have 2 doubts i) distance metric have use find nearest node in graph? if euclidean distance,how calculate because there 2 links in each arm configuration of robot , have no idea how find euclidean distance in case. how find distance between ade , abc if abc nearest config ade in tree? ii) how generate random config towards goal because random configs never seem reach goal after 5000 iterations. thanks in advance. distance metrics 2 revolute-joint arm rrt pretty robust (pseudo-) metric choose, quality of trees (and consequently paths) influenced if you've got isn't particularly good. performance overall, metric function supposed fast, i'd try simpler things before move onto more complex. in case of robot arms number of metrics possible. perhaps simplest use euclidean distance between end effector in 2 configurations. you'll have have working if you're testing planning algorithm.

after browsing while available solutions, hard choose appropriate tool creating dashboard & populating plots. want have html page multiple plots , tables depicted. i'm thinking have data input stored in csv files, appropriately formatted. the requirements are: plot coordinates showing on mouse hover ability show coordinates of points on plotted line (points in scatter plot or bar values bar chart) 'sticking' nearest lines on hover, appropriate handling of multiple lines (show several y values same x) ability interactively switch plotted data on/off easily embeddable html page, doesn't require additional plugins installed a variety of plot types not slow load , stable, there ~50 plots on 1 page (this internal use only, quickness not important) does minimal effort so far checked out (by no means final opinion, correct me if i'm wrong): gnuplot+canvas - looks good, samples on page fail work me, not getting mouse clicks right python+matplotlib

here code: ftpconnection ftp = new ftpconnection(configurationmanager.appsettings["server"], configurationmanager.appsettings["user"], configurationmanager.appsettings["password"]); ftp.open(); ftp.login(); ftpfileinfo[] files = null; if (ftp.directoryexists(some_name)) { ftp.setcurrentdirectory(some_name); files = ftp.getfiles("*.xlsx"); string filename = files[0].name; } return; everything works well. filename variable has correct name. error code 500 though nothing crashed. error says: absolute path information required. what mean? how fix it? when debugged noticed when expand properties of files, there 1 property exists, has exact same error. see below link(s) although not exact same issue - should point in right direction? link1 link2 hope helps

i using sql server 2008 express r2 , have table self referencing, because have hierarchy struct. i need delete root node, error because of foreign key. have read can use 2 option, use recursive cte o use instead of delete trigger. which difference brtween both of them? more efficient? thanks. when use delete trigger opposed recursive cte, assume going kind of loop in trigger, mean cte more efficient. for cte, try like: with cte ( select id root, parent, id [<yourtable>] parent null -- selects root nodes union select cte.root, d.parent, d.id cte inner join data d on cte.id = d.parent ) delete [<yourtable>] [<yourtable>] inner join cte on rel.id = cte.id cte.root = 1 -- root delete

i have class in scala, constructed in standard manner: class test( int : int ) { override def tostring() = "test: %d".format( int ) } however, i'd move on indirect construction via companion object. library i'm modifying used others, don't want make constructor private straight away. instead, i'd deprecate , come , make private once people have had chance change usage. modified code this: object test { def apply( int : int ) = new test( int ) } @deprecated( "don't construct directly - use companion constructor", "09/04/13" ) class test( int : int ) { override def tostring() = "test: %d".format( int ) } however, deprecates whole class. scala> test( 4 ) <console>:10: warning: class test in package foo deprecated: don't construct directly - use companion constructor val res0 = ^ res0: com.foo.test = test: 4 does know if scala supports deprecation of constructors, , if
