What blocks Ruby, Python to get Javascript V8 speed? -

-

are there ruby / python features blocking implementation of optimizations (e.g. inline caching) v8 engine has?

python co-developed google guys shouldn't blocked software patents.

or rather matter of resources put v8 project google.

what blocks ruby, python javascript v8 speed?

nothing.

well, okay: money. (and time, people, resources, if have money, can buy those.)

v8 has team of brilliant, highly-specialized, highly-experienced (and highly-paid) engineers working on it, have decades of experience (i'm talking individually – collectively it's more centuries) in creating high-performance execution engines dynamic oo languages. same people created sun hotspot jvm (among many others).

lars bak, lead developer, has been literally working on vms 25 years (and of vms have lead v8), entire (professional) life. of people writing ruby vms aren't 25 years old.

are there ruby / python features blocking implementation of optimizations (e.g. inline caching) v8 engine has?

given @ least ironruby, jruby, maglev, macruby , rubinius have either monomorphic (ironruby) or polymorphic inline caching, answer no.

modern ruby implementations great deal of optimizations. example, operations, rubinius's hash class faster yarv's. now, doesn't sound terribly exciting until realize rubinius's hash class implemented in 100% pure ruby, while yarv's implemented in 100% hand-optimized c.

so, @ least in cases, rubinius can generate better code gcc!

or rather matter of resources put v8 project google.

yes. not google. lineage of v8's source code 25 years old now. people working on v8 created self vm (to day 1 of fastest dynamic oo language execution engines ever created), animorphic smalltalk vm (to day 1 of fastest smalltalk execution engines ever created), hotspot jvm (the fastest jvm ever created, fastest vm period) , oovm (one of efficient smalltalk vms ever created).

in fact, lars bak, lead developer of v8, worked on every single one of those, plus few others.

c# - How to set Z index when using WPF DrawingContext? -

-
how set z-index drawing object when using drawingcontext.drawxxx() methods? the object drawn last have higher z index. can't change index of drawn objects. way draw in order. if using wpf (as placed tag), can use, example, canvas control. create shapes need like polyline obj = new polyline(); //... // ... set properties of obj and add them canvas uielementcollection: yourcanvasname.children.add(obj); //or yourcanvasname.children.insert(i, obj); first items of collection have higher z index. advantages in way: no need redraw on window changes, can anytime move objects , change order.

razor - Is this a bug in WebMatrix PageData? -

-
i think may have found bug in webmatrix's pagedata, not sure. concerns how pass data partial page calling page. in webmatrix documentation (tutorials, e.g. " 3 - creating consistent look ", , example code), pagedata recommended mechanism pass data between pages (e.g. content page layout page, or partial page). however have found not work other way, pass data partial page calling page. modifying or adding entries in pagedata in partial page, not seem calling page. cutting right down simplest possible example, in test page may have this: @{ pagedata["test"] = "initial entry"; } <p>before calling partial page, test value @pagedata["test"]</p> @renderpage("_testpartial.cshtml") <p>after returning calling page, test value @pagedata["test"]</p> and in _testpartial.cshtml page might have this: @{ pagedata["test"] = "modified entry"; } <p>in partial page...

visual c++ - Using relative values in array sorting ( asm ) -

i need sort through array , sort each individual row in array in ascending order. doesn't seem going (surprise!) keep getting hit 2 errors: a2101: cannot add 2 relocatable labels , a2026: constant expected here's sort, makes sense me, think i'm still trying implement high-lvl language techniqes assembly. there way around not being able use relative values? (the array 7 rows 9 columns, btw). mov cx, 7; cx = number of rows outer: ; outer loop walk through rows push cx mov cx, 9 mov row, cx ;rows middle: ; middle-loop walk through columns push cx sub cx, 1 ;cx = cx-1 mov column, cx ;columns inner: ;inner loop - compare , exchange column values cmp marray[row*9 + column], marray[row*9 + column+1] xchg marray[row*9 + column+1], marray[row*9 + column] ; compare , exchange values marray table inc column loop inner pop cx loop mid...
