i reading csapp, in chapter 4, there discussions cpu pipelining features author talks how many instructions non-pipelining cpu can execute within 1 second vs pipelining cpu. post screenshot follows: in figure 4.32(a) shows unpipelined cpu. in implementation, must complete 1 instruction before beginning next. big box combinational logic. author regard whole process instruction , calculates throughput 3.12 gips shown in formula. then author use figure 4.33 show pipeline computation: in pipeline computation, combinational logic can divided 3 stages i1, i2 , i3. here question: in opinion, because these 3 stages combined product effect of combinational logic, think of 3 stages single instruction author did in unpipelined example. however, author seems regard 3 stages 3 instructions, , got throughput of 8.33 gips follows: so curious definition of instruction? (if think of writing registers instruction, author's answer correct)

is there way can iteration number inside angular foreach (when iterating through object : {'foo': 'blah', 'blah': 'foo'} ? iterator function in case, value 'blah' , 'foo' while key 'foo' , 'blah' angulars foreach when iterating object doesn't tell how many times iterated objects keys. when iterating array doesn't tell how many times ran current position in array. it's me being pedantic there difference. however alternative give current position in objects keys use native object.keys() . return array of objects keys, can iterate on them normal array , current position in array. var obj = {'foo': 'blah', 'blah': 'foo'}; object.keys(obj) .foreach(function (key, index) { console.log('key', key, 'value', obj[key]); console.log('ive ran ', index); }); docs: https://developer.mozilla.org/en-us/docs/web/javascript/r...

having output of list of lists containing index values of grouped elements (somewhat) corresponding list of tuples, how combine them list of grouped tuples? data=[(1, 1), (1.5, 2), (3, 4), (5, 7), (3.5, 5), (4.5, 5), (3.5, 4.5)] clusters=[[0], [], [4], [1, 2, 3, 5, 6]] these sample values/groups. example of i'm asking about: coordinates= [[(1,1)], [], [(3.5,5)], [(1.5,2),(3,4),(5,7),(4.5,5),(3.5,4.5)]] i've tried list comprehensions , zips when comes getting value of [i] in clusters gets confusing. i think two-level list comprehension want: coordinates = [[data[index] index in cluster] cluster in clusters]

what best way following? i reverse smaller range in vector , haven't found better solution this: extract smaller range newly created vector, reverse , add newly created vector @ former position in original vector. another way explain want this: original vector: 1 2 3 4 5 6 7 8 9 10 11. wanted result:   1 2 3 4 5 6 7 10 9 8 11. copy 10, 9, 8 in order new vector 3 element or copy element 8, 9, 10 new vector reverse it. original vector consists of 9 elements because elements 8, 9, 10 erased in procedure. 2.the new vector 3 elements 10, 9, 8 copied/appended original vector @ position 8 vector or element element @ position 8, 9, 10 respectively. i sure there better solutions method mentioned above. you in fact write in-place swap, that gets last , first index swap, swap these, decreases last index , increases first index, and repeats until last_index - 1 <= first_index . now, sounds less copying me, stroustrup himself once said: i don't ...
