i want execute program (written in racket) on raspberry pi when doing so, doesn't know functions defined in file. the small example below gives rise following error on raspberry pi : default-load-handler: expected 'module' declaration "test", found: else in: ... file i'm executing on raspberry pi : (require "test.rkt") (display "2 + 2 = ") (display (plus 2 2)) the "test.rkt" file : (provide plus) (define (plus b) (+ b)) when executing file doesn't display gives rise error listed above. note files don't contain : "#lang racket". because if contain it, loading file nothing. so following file nothing when loaded on raspberry pi : #lang racket ; when omitting "hello world!" displayed, else not (display "hello world!")

we've copied api have being iis hosted console app (to hosted owin + topshelf service) , have been performance profiling 2 hosting options using jmeter. we throw 18 threads @ apis , differing results iis hosted vs console hosted, follows : response times through iis slower. isn't surprising pipeline in iis more involved. throughput through iis consistent, i.e. don't see significant increases/decreases in throughput (we achieve 5500 requests/responses per min) throughput when hosted in console app starts off high (20,000 per min) degrades approximately 4,500 per min on 10 minute period. we're trying determine cause of throughput drop when hosting console. why start 20,000 requests per min (presumably calculated on initial response times when hasn't run minute) degrade 4,500? other things of note, cpu isn't concern. it's fluctuates start settles below 30% available, , memory average 1.34gb on 4gb ram machine. why might throughput in iis stabl...

this question exact duplicate of: does python have versioned dependency management solution? 1 answer are there practical solutions maintaining multiple versions of library in python environment? for example, have 1 web framework using pluggable design. under framework, there can several applications registered (application , framework running in same python process). each application have business logic code , common code, common_httplib . problem how can ensure multiple versions of common_httplib don't conflict each other? each application expected use own copy of common_httplib different versions. absolute import, import hook, imp etc. don't work because common_httplib may import other third party libraries may have same version problems. following code structure of applications. under $framework_home/apps/ , there is: /app1 /common_htt...

this question has answer here: better way convert list vector? 2 answers in r, give list l1 <- list(a = "a", b = "b", c = "c") and vector v<- c("a", "c") how elements list in vector? example l1[v] returns list, while need vector as c("a", "c") looking fastest one-liner . you can try this, similar @colonelbeauvel identical(as.vector(unlist(l1[v])), c("a", "c")) [1] true

i have following code gives warning "possible unintended reference comparison; value comparison, cast right hand side type string ": // ocontrol of type control if ((ocontrol.name == odatarowview["conname"].tostring())) { //do stuff } else { //do other stuff } i've tried fix using each of following still warning if ((ocontrol.name == convert.tostring(odatarowview["conname"]))) { //do stuff } else { //do other stuff } if ((ocontrol.name == (string)odatarowview["conname"])) { //do stuff } else { //do other stuff } please explain reason still warning , best practice way deal this? these options work: if (equals(ocontrol.name, odatarowview["conname"])) // best option if ((string)ocontrol.name == odatarowview["conname"].tostring()) // assuming neither item null if (ocontrol.name string == odatarowview["conname"] string) // assuming second item string

i've been trying reduce code used in voxel / planar terrain generator, , wrote function in order call every time need add new set of uv's - representing 4 vertex in texture map: list<vector2> _uvs(list<vector2> uv, int x = 0, int y = 0) { list<vector2> uvreturn = new list<vector2>(); uvreturn = uv; uvreturn.add(new vector2 (0f, 0f) * x); uvreturn.add(new vector2 (0.125f, 0) * y); uvreturn.add(new vector2 (0.125f, 1)* y); uvreturn.add(new vector2 (0f, 1f) * x); return uvreturn; } however, can't seem identify exact spots write in modifiers, seem throw things off every time. have single row of 128x textures in 1024 file. uv layout moment seems exact, except multiplication. remove , shows first texture, perfectly. ways can improved on? goal used 4 vertex plane. you can't multiply that, that's different. uvreturn.add(new vector2 (x * 0.125f, 0f)); uvreturn.add(new vector2 ((x + 1) * 0.125f, 0)); uv...
