we have issue want lazily create entity if not exist. there discussion going on how , clarify things around app engine transactions. limit query single entity group transactions. i using go in examples, hope code clear enough non-go programmers. my understanding transaction, on single entity group, succeed if entity group not modified externally during transaction. 'entity group timestamp' indicating when entity group changed stored in root entity of entity group. during transaction current 'entity group timestamp' read , transaction can succeed if hasn't changed end of transaction. key := datastore.newkey(c, "counter", "mycounter", 0, nil) count := new(counter) err := datastore.runintransaction(c, func(c appengine.context) error { err := datastore.get(c, key, count) if err != nil && err != datastore.errnosuchentity { return err } count.count++ _, err = datastore.put(c, key, count) return err }, nil) in example...

so, expect sort, isn't. _.uniq(array, [issorted], [iteratee], [thisarg]) so _.uniq([10,3,13,1,0,2], true); i run that, , doesn't sort. i'd expect return: [0,1,2,3,10,13] that's not issorted parameter does. [issorted] (boolean): specify array sorted. - https://lodash.com/docs#uniq does not mean sort array if set true it's expecting sorted array. providing true issorted performs faster search algorithm sorted arrays. it's optimization in algorithm "creates duplicate-free version of array" lot faster if array sorted.

i regular expression string server. example js_pattern = "/^9\d+$/" and need string same regular expression (without modifications) js_regexp = /^9\d+$/ re = new regexp(js_pattern) doesn't work me because in case /\/^9d+$\// are there correct variants convert string regular expression in javascript? any non-special character gets evaluated character in string . for example // true, because it's non-special gets evaluated character. console.log("\a" === "a"); // true // false, because it's new line special character. console.log("\n" === "n"); // false javascript special characters solution: escape backslashes on server before send over.

i have blob column in table, using mysql. i'm trying value getstring method of resultset, rs.getstring("xxxxxx") i'm not sure if there problem in situation. dose depend on stored in column? can this? it doesn't matter stored in database. doesn't matter string or int. data query result , interpreted string. string not sequence of bytes. reference object expected string. means reference points structure in memory structure of other references. so, when take sequence of bytes , assume reference object then, likely, have runtime exception. classcastexception knows data has. exception unpredictable in case. bottom line - don't this.

i have 20 different sprites. want "flow" of them falling top , disappearing when reach bottom. essentially, imagine rain each drop random sprite. want each sprite fall random rotation , each "drop" random sprite selection of 20. can please point me in right direction? i've never made game before , first time working spritekit. i'm using swift way. thanks! make use of arc4random random sprite selection of 20 sprites adding sprites group. arc4random able random rotation you. for them fall down top bottom, can apply -gravity them or apply -impulse. to check whether have reached bottom, y value when disappear off bottom of screen , use comparision value , use removefromparent(). alternatively third method use movement of skaction , adjust y coordinate. @ end of completion block use removefromparent().

i'm building feature require web publishers put js code snippet in section of page in order work. code includes call external (and dynamically generated) js file remote server. file cannot cached putting on cdn isn't option. what i'm worried if there ever problem remote server make remote file unreachable, can take down page in code included (potentially entire site code suppose included site-wide). is there way make sure no matter what, availability of remote file never affect availability of page in code included? -edit- resources in remote file need available before html of page starts render. loading code asynchronously isn't option. you specify async=true not "block" page resuming loading other resources. otherwise it'll halt @ script, though may vary depending on how each browser handles stalling script elements. note: support of async attribute varies - modern browsers circa 2014 understand if need support legacy browsers may ...

if have following ienumerable list comes repository. ienumerable<someobject> items = _somerepo.getall(); what faster: items.count(); // using linq on ienumerable interface. or list<someobject> temp = items.tolist<someobject>(); // cast list temp.count(); // count on list is linq count() faster or slower casting ienumerable list , performing count() ? update: improved question little bit bit more realistic scenario. calling count directly better choice. enumerable.count has performance improvements built in let return without enumerating entire collection: public static int count<tsource>(this ienumerable<tsource> source) { if (source == null) throw error.argumentnull("source"); icollection<tsource> collectionoft = source icollection<tsource>; if (collectionoft != null) return collectionoft.count; icollection collection = source icollection; if (collection != null) return collec...

in c i'm reading string txt file, example string "hello", have my: f=fopen("text.txt","r"); fscanf(f,"%s\n",string); now, if want convert string hex , decimal, can this: for (i=0; i<strlen(string); i++) { sprintf(st, "%02x", string[i]); //convert hex strcat(hexstring, st); sprintf(st, "%03d", string[i]); //convert dec strcat(decstring, st); } now, question is: want inverse operation, how? output if convert "hello" hex-> 68656c6c6f dec-> 104101108108111 from "68656c6c6f" or "104101108108111" want go "hello", how can this? (basically want website: http://string-functions.com/ ; string hex converter, hex string converter, decimal hex, converter, hex decimal converter) the challenge realize have string of hex , string of decimal, meaning have character string representation of values, not values themselves. need convert stri...

based on request, query either test_users or users . doing using user.table_name = "test_users" or user.table_name = "users" this works in development, not in production (i.e table name in query not change), due - config.cache_classes = true config.eager_load = true i guessing table names being cached somewhere , model.table_name= not update cache. how can switch table name dynamically? running 4.2.0 , if helps postgres (pg gem).

yesterday in class, , @ point instructor talking c code. said: what purpose of making pointer cast in c? purpose make compiler interpret correctly pointer operations (for example, adding int pointer result in different offset adding char pointer). apart that, there no difference: pointers represented same way in memory, regardless if pointer pointing int value, char value, short value, or whatever. so, casting pointer not modify in memory, programmer operations more related pointer-type dealing with. however, have read, specially here in stack overflow, not 100% true. have read in weird machines, pointers different types can stored in different ways in memory. in case, not changing pointer correct type cause problems if code compiled kind of machine. basically, kind of code i'm talking about. consider code below: int* int_pointer; char* char_pointer; int_pointer = malloc(sizeof(int)); *int_pointer = 4; and 2 options: 1. char_pointer = (char *)int_pointer...

i have code creating internal file, there random algorithem create data stored in , want app have same file same binary data in it. so need make file on desktop , add internal files how. my question think best way it. thought locate in project, read it, , write internal files. the problem is, dont know locate file in android studio included in external files , read from. thanks. =] hope made myself clear. put in src/main/assets/ . you can access file assetmanager , whatever want it. from android developers website : main/assets/ this empty. can use store raw asset files. files save here compiled .apk file as-is, , original filename preserved. can navigate directory in same way typical file system using uris , read files stream of bytes using assetmanager . example, location textures , game data.
