opengl 2.0 - openGL2.0: How to disable vertex shaders? -


i trying capture traces game glinterceptor use doesn't support vertex shaders. research suggests disable vertex shaders , use default vertex shader no information how it. so, how can disable vertex shaders? here code:

pp.fx

#define disable_fog #define disable_lighting  technique default {   pass p0   {     vertexshader = vertexshaders/diff-tex.vs;     pixelshader = pixelshaders/pp.ps;      #ifdef enable_twosided         enableculling = false;     #endif      #ifdef disable_depth_test         enabledepthtest = false;     #endif      #ifdef enable_additive         enabledepthmask = false;         enableblending = true;         blendfuncsrc = one;         blendfuncdst = one;     #endif      #ifdef enable_multiplicative         enabledepthmask = false;         enableblending = true;         blendfuncsrc = dst_color;         blendfuncdst = zero;     #endif      #ifdef enable_alpha_blending         enabledepthmask = false;         enableblending = true;         blendfuncsrc = src_alpha;         blendfuncdst = one_minus_src_alpha;     #endif      #ifdef enable_premult_alpha_blending         enabledepthmask = false;         enableblending = true;         blendfuncsrc = one;         blendfuncdst = one_minus_src_alpha;     #endif   } }

diff-tex.vs

commonjs - How to write a typescript definition file for a node module that exports a function? -

consider, toml node module can use: // toml.d.ts declare module toml { export function parse(value:string):any; } declare module "toml" { export = toml; } then: /// <reference path="../../../../../defs/toml/toml.d.ts"/> import toml = require('toml'); toml.parse(...); however, node module export single function, such 'glob' ( https://github.com/isaacs/node-glob ). the node usage of module be: var glob = require("glob") glob("*.js", {}, callback(err, files) { ... }); you'd naively expect this: // glob.d.ts declare function globs(paths:string, options:any, callback:{(err:any, files:string[]):void; ...but because typescripts 'import' semantics bit strange, seems can use 'import .. = require()' statement alias modules . trying call: /// <reference path="../../../../../defs/glob/glob.d.ts"/> import blog = require('glob'); results in: error ts2072: mod

openid - Okta: Failed to get authorization code through API call -

i'm integrating okta own idp server using okta's api. i'm implementing authorization code flow following steps below: in own server, use /api/v1/authn endpoint sessiontoken. use sessiontoken obtain authorization calling endpoint: /oauth2/v1/authorize?client_id=" + clientid + "&sessiontoken=" + sessiontoken + "&response_type=code&response_mode=query&scope=openid&redirect_uri=" + redirecturl + "&state=evanyang&nonce=" it's supposed return response status code 302 , location header containing redirect url code value. however, keep getting response status code 200 , without location header, html body saying "you using unsupported browser." , "javascript disabled on browser." according api documentation: http://developer.okta.com/docs/api/resources/oidc.html#authentication-request , sessiontoken parameter sufficient this: an okta one-time sessiontoken. allows api-based

thorough guide for profiling racket code -

did googling ("racket profiling", "racket measure performance"), didn't find , there no examples in docs. did google "profile" search on htdp - no luck. (profile (f ...)) output isn't obvious other small snippets. ideally want python's python -m cprofile usage examples. when search "python profiling", both duckduckgo , google give top result: 26.4. python profilers . (although scanned quickly, seems more of reference "thorough usage guide" examples. if had else in mind, perhaps please link that?) the equivalent racket documentation be: profile: statistical profiler . a usage example: #lang racket (require profile) (profile-thunk (thunk (function-to-profile arg0 arg1) )) here (thunk e) convenience (lambda () e) . bigger example: #lang racket (module mod racket (provide f) (define (f) (for/list ([i 10000]) i))) (require (prefix-in mod: 'mod)) (define (f) (for ([i 10000
