i've written routine interpolates point data onto regular grid. however, find scipy 's implementation of nearest neighbor interpolation performs twice slow radial basis function i'm using linear interpolation ( scipy.interpolate.rbf ) relevant code includes how interpolators constructed if interpolation_mode == 'linear': interpolator = scipy.interpolate.rbf( point_array[:, 0], point_array[:, 1], value_array, function='linear', smooth=.01) elif interpolation_mode == 'nearest': interpolator = scipy.interpolate.nearestndinterpolator( point_array, value_array) and when interpolation called result = interpolator(col_coords.ravel(), row_coords.ravel()) the sample i'm running on has 27 input interpolant value points , i'm interpolating across 20000 x 20000 grid. (i'm doing in memory block sizes i'm not exploding computer btw.) below result of 2 cprofile s i've run on relevant code. note ...

could explain why can not use int() convert integer number represented in string-scientific notation python int ? for example not work: print int('1e1') but does: print int(float('1e1')) print int(1e1) # works why int not recognise string integer? surely simple checking sign of exponent? behind scenes scientific number notation represented float internally. reason varying number range integer maps fixed value range, let's 2^32 values. scientific representation similar floating representation significant , exponent. further details can lookup in https://en.wikipedia.org/wiki/floating_point . you cannot cast scientific number representation string integer directly. print int(1e1) # works works because 1e1 number float. >>> type(1e1) <type 'float'> back question: want integer float or scientific string. details: https://docs.python.org/2/reference/lexical_analysis.html#integers >>> int("13.3...

we medium level organization around 40 developers. have multiple branches different releases simultaneous development. the problem face when merge release-branch on master is, there 2 many commits involved , overwhelming understand changes went in , developer merging branches unable decide chunks let in , not. auto-merged files catching lots of wrong merges. how big companies go doing these merges in more efficient , collaborative way? popular git workflows aware of? create new merged branch , ask developers check/comment if merge happened , merge master? please advice i suggest @ pull requests. they way @ has changed 1 branch and, because can add many approvers wish, many developers can review , comment wherever want, creating discussion changes merged. in experience, used on atlassian stash , nice collaborate on merge. suggest @ this documentation atlassian, part "discussing pull request". pull requests used lot on github, merge contribution fork i...

i using javascript , know positions of 3 points. wish use these find out center point of circle. i have found logic (not chosen answer 1 11 upvotes) : https://math.stackexchange.com/questions/213658/get-the-equation-of-a-circle-when-given-3-points but can't seem head around how write logic it. i can't use bounding box way, has done using 3 points :) any ideas ? my favorite resolution : translate 3 points bring 1 of them @ origin (subtract (x0,y0) ). the equation of circle through 2 points , origin can written 2x.xc + 2y.yc = x² + y² plugging coordinates of 2 points, easy system of 2 equations in 2 unknowns, , cramer xc = (z1.y2 - z2.y1) / d yc = (x1.z2 - x2.z1) / d d = 2(x1.y2 - x2.y1), z1 = x1²+y1², z2 = x2²+y2² to translated (add (x0,y0) ). the formula fails when 3 points aligned, diagnosed d = 0 (or small in comparison numerators). x1-= x0; y1-= y0; x2-= x0; y2-= y0; double z1= x1 * x1 + y1 * y1; double z2= ...

i'm struggling on appending additional conditions query. in simplest form, need below: def findpeople(name: string, maybesurname: option[string]) = { val sql1 = sql"select * my_table name = $name" val sql2 = maybesurname.map( surname => sql"and col2 = $surname" ).getorelse(sql"") val finalsql = sql1 + sql2 // need kind of feature ... ... } using #$ option, surname wouldn't bind variable, big issue. here sample test on slick 3.1.x import slick.jdbc.{sqlactionbuilder, setparameter, positionedparameters} object slickkit { implicit class sqlactionbuilderconcat (a: sqlactionbuilder) { def concat (b: sqlactionbuilder): sqlactionbuilder = { sqlactionbuilder(a.queryparts ++ b.queryparts, new setparameter[unit] { def apply(p: unit, pp: positionedparameters): unit = { a.unitpconv.apply(p, pp) b.unitpconv.apply(p, pp) } }) } } } and then import slickkit._ v...

i haven't checked many dialects yet (in pharo association subclass of lookupkey , subclass of magnitude ) presume common. isn't definition counterintuitive? associations take part in unordered collections , don't think smalltalker ever takes account keys sent #<= . know whether inherited old implementations of smalltalk , never bothered challenge, or me missing something. bottomline: has ever used feature? i don't think dictionary needs that; needs = , hash. however, want list of associations , sort them later (eg. show them in sorted list). then, nice have order defined already. and cost "<" method in association (or lookupkey, if superclass), comes free inheriting magnitude instead of object.
