applet - Unable to send 128 Bytes data from Javacard but can send 127 Bytes as a response to APDU command when using sendBytesLong() -


while sending data javacard in form apdu commands using apdu.sendbyteslong() function, able send 127 bytes data response 128 bytes data give error code 6f00(sw_unknown). why happening , can suggest way around without splitting data 2 apdu commands.

le = apdu.setoutgoing();             if(le != 128)                 isoexception.throwit(iso7816.sw_wrong_length); apdu.setoutgoinglength((byte)le); apdu.sendbyteslong(mod_pkaikr,(short)0, le);

where mod_pkaikr byte array of 128 bytes.

thank

change apdu.setoutgoinglength((byte)le); apdu.setoutgoinglength(le);

  1. the parameter type of api apdu.setoutgoing() short, didn't needs type convert.
  2. if convert le type byte, parameter value nagative. value of (byte) 128 -128.

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

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
