i reading threads in os concepts , come across "thread local storage (tls)". understood tls similar static or global data, more unique individual thread. bit confusing on unique here? why can't pass data through runner (i.e., thread's actual codes) functions params function? let's supposed working in ada. in ada program define task (thread) includes [static] variable can accessed task. create multiple instances of task. need copy of [static] variable each task. that's implementation use thread local storage. in other words, static area of memory gets copied each thread in program. as alternative tls, thread allocate such storage @ top of stack.

suppose api given , cannot change it: object providerapi { trait receiver[t] { def receive(entry: t) def close() } def run(r: receiver[int]) { new thread() { override def run() { (0 9).foreach { => r.receive(i) thread.sleep(100) } r.close() } }.start() } } in example, providerapi.run takes receiver , calls receive(i) 10 times , closes. typically, providerapi.run call receive(i) based on collection infinite. this api intended used in imperative style, external iterator. if our application needs filter, map , print input, need implement receiver mixes these operations: object main extends app { class myreceiver extends providerapi.receiver[int] { def receive(entry: int) { if (entry % 2 == 0) { println("entry#" + entry) } } def close() {} } providerapi.run(new myreceiver()) } now, question how use providerapi in functional style, internal ...

i trying use default namespace '\' connecting general android application sockets socket.io , want make custom namespace website '/web' when client io.connect('/web') connects default namespace. basically want authorization of all, not /web namespace. here code io.sockets.on('connection', function (socket, next) { //some handshaking data varify connection } io.of('/web').on('connection', function(socket, next) { //here want skip verification } got request on default instead of /web. socket.io connection event trigger / default namespace on socket connections. later events client trigger on namespace connected to.

i'm writing down here because i'm having lots of issues thing, , hope able me out :p i want create dynamic stackpanel fits children's width. i'll make example. let's stackpanel empty. width 10 (f.e.) , fixed height 30. want add image, , wrote down: bitmapimage myimage = new bitmapimage(new uri("[path]")); image realimage = new image(); realimage.source = myimage; realimage.width = 50; realimage.height = myimage.height; mystackpanel.children.add(realimage); the stackpanel not enlarge 50px though; it's stuck 10px, cutting image. same happens when try add other ui elements, textblocks , on. i tried like mystackpanel.width += realimage.width; but of course didn't work. i've tried set stackpanel's width "auto", didn't either. stackpanel declaration in xaml: <window x:name="mainwindow1" x:class="proj.mainwindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"...

i'm trying read in bits using read function , i'm not sure how i'm supposed printf results using buffer. currently code fragment follows char *infile = argv[1]; char *ptr = buff; int fd = open(infile, o_rdonly); /* read */ assert(fd > -1); char n; while((n = read(fd, ptr, size)) > 0){ /*loops reads file until returns empty */ printf(ptr); } the data read ptr may contain \0 bytes, format specifiers , not \0 terminated. reasons not use printf(ptr) . instead: // char n; ssize_t n; while((n = read(fd, ptr, size)) > 0) { ssize_t i; (i = 0; < n; i++) { printf(" %02hhx", ptr[i]); // on older compilers use --> printf(" %02x", (unsigned) ptr[i]); } }

this question has answer here: how functions's body string? 2 answers for example, if have this: function hello() {console.log("hello")} i want able make function in java script return string value: "console.log("hello");" is there way plain javascript? you can of code including function declaration calling tostring() method on function. can parse string remove unwanted information. something this: function hello() { console.log("hello"); } var f = hello.tostring();//get string of whole function f = f.substring(f.indexof('{') + 1);//remove declaration , opening bracket f = f.substring(0, f.length - 1);//remove closing bracket f = f.trim();//remove starting/eding whitespace console.log(f); here working example

as title says i'm compiling linux kernel android patches. i'm being asked few configuration questions first time compiling. asked following question: physical address of decompressed kernel_image (zreladdr) [] (new) i don't know are asking. think odd asking specific address in memory. 1 familiar this? some updated info: source of question arch/arm/kconfig i found google's recommended config here: http://source.android.com/devices/tech/kernel.html i'm trying make connection between 2 now. guess need read on how .config files work i figured out how through issue. turns out previous question asking if wanted decompressed kernel image address auto-calculated had said 'no' to(this default). still can't imagine situation want manually specify address of kernel image though & i'm wondering if skipping question right thing default have answer it.

i using mysql. here's example, want rename table b, what's difference between following statement: alter table rename b; and one: rename table b; can give detail compare between them? vary based on different engine? as documented under alter table syntax : for alter table tbl_name rename new_tbl_name without other options, mysql renames files correspond table tbl_name without making copy. (you can use rename table statement rename tables. see section 13.1.32, “ rename table syntax” .) privileges granted renamed table not migrated new name. must changed manually. as documented under rename table syntax : you cannot use rename rename temporary table. however, can use alter table instead: mysql> alter table orig_name rename new_name ; there no other differences.

why breaking? i've not used .innerhtml correctly before , don't know why wrong. function asdf() { document.getelementbyid("qwerty").innerhtml="a<br> b<br> c<br> d<br>"; } you have escape new-lines in javascript string-literals: function asdf() { document.getelementbyid("qwerty").innerhtml="a<br>\ b<br>\ c<br>\ d<br>"; } though could, potentially more-easily, insert newlines in string itself: function asdf() { document.getelementbyid("qwerty").innerhtml = "a<br>\nb<br>\nc<br>\nd<br>"; }

i want clear datagridview starting row user chose. trying few ways implement it, generate errors, have this: foreach(datagridviewrow row in this.datagridview1.rows) { if(row.index >= odelementu - 1) datagridview1.rows.removeat(row.index); } user need choose row should clear datagridview , click button odelementu //this variable represents starting row i don't know why loop misses rows. grateful advices it's because modify datagridviewrowcollection in foreach loop , make index gotten becomes inexact . try instead: while(datagridview1.rows.count>=odelementu) { datagridview1.rows.removeat(odelementu-1); }
