in current work, have written code generator using string template without thinking parser ( instantiating template files using direct java object). , code generator generator generates nice java code. now, have started write parser. b'coz of nice editor features of xtext, thinking write parser in xtext. my question "is possible use code generator ( written using stringtemplate ) , parse (written in xtext) in same project? yes that's possible. xtext offers typed ast parsed files , pass them code generator (directly, iff fulfil same contract / interfaces, or indirectly transforming them expected structure). xtext not impose constraints on how want use parsed information.

is possible exec ruby code in instance variable in controller? example: def @code = "redirect_to 'https://www.google.com/'" exec(@code) // , redirect. end don't this. rails ruby. in ruby, can execute command inside string using eval method. , when start getting it, there class_eval. @myvar = "puts 'should not have done this!!'" eval(@myvar) # should not have done this!! keep safe.

i'm trying make use of lvm2 functionality in linux (centos6.0). when trying make first step of defining pv on specific block device, following error message: [root@localhost /] pvcreate /dev/sdb can't open /dev/sdb exclusively. mounted filesystem? /dev/sdb not mounted , partition table deleted. should mention /dev/sdb used represent larger block device (about 4 times larger) , reduced configuration of hardware raid (i split hd 4 in raid controller). has ever encountered error before , knows how take here? maybe device-mapper 'stealing' device. try this: [root@host ~]# dmsetup ls sdb (253, 2) volgroup00-logvol01 (253, 1) volgroup00-logvol00 (253, 0) if find sdb device listed above example, remove using dmsetup , create physical volume: [root@host ~]# dmsetup remove sdb [root@host ~]# pvcreate /dev/sdb physical volume "/dev/sdb" created

i started drawing hexagonal grid on canvas path object. did calculations on how many hexagons go on particular display, depending on hexagon size. i have hexagon coordinates calculated depending on canvas. now, have serious performance issues , have port opengl. because algorithm works in canvas, i'm trying convert "canvas" hexagon coordinates opengl coordinate system glu.gluunproject. "for loop" float near[] = { 0.0f, 0.0f, 0.0f, 0.0f }; glu.gluunproject(b.hexes[ii][jj].points[ii].x, b.hexes[ii][jj].points[ii].y, 0, mg.mmodelview, 0, mg.mprojection, 0, viewport, 0, near, 0); vertices[zz] = (float) ((near[0])/near[3]); zz++; vertices[zz] = (float) ((near[1])/near[3]); zz++; vertices[zz] = 0; because lack opengl knowledge, dont know how set glviewport,gluperspective,gltranslatef 2d world "the same" canvas. so question is: how set 3 thing...

as example clarify question, in google go 1.0, following interface defined in "io" package : type reader interface { read(p []byte) (n int, err error) } especially result parameter list (n int, err error) intrigues me. intrinsically number of bytes can not negative, according documentation of interface: it returns number of bytes read (0 <= n <= len(p))[...] in c reason use int in-band value -1 signal error condition (see effective go: multiple return values ). because of multiple return values, special in-band values not necessary. there exists type uint in go 1.0. what specific reason using int versus uint in case of values use positive range [0,∞) without need having special in-band values? the de facto numeric type integers in cases int . example, len(x) , cap(x) return int values though cannot negative. in cases returning int helps avoid type conversions between different numeric types. so yes, read() have returned uint ...

when doing preliminary research, minimum requirements ios development limited intel based mac, snow leopard. since then, have purchased new (old) mac, installed sdk (4.3), , wrote first app. unfortunately, highest sdk mac run ios 4.3. iphone want test ios 5.x. cannot figure out how set provisioning allow me install app on iphone. have paid fee, went through brief (aimed @ later sdk) helper, xcode wants me install older ios on phone connect. know way around this? thanks in advance, sagan create ad hoc build, , load resulting .ipa file onto device either via itunes or url. ad hoc builds allow create built copy of app in single packaged file may loaded on device. there's ton of references around web how this, here's 1 guide xcode 4: http://benscheirman.com/2011/06/creating-proper-ipa-files-in-xcode-4 here's guide xcode 3: http://www.springtiger.co.uk/2010/12/06/creating-a-ipa-file-for-your-application/
