  • What's faster to parse lots of data (5Mb): eval or json?

    - by AlfaTeK
    I want to get, via ajax, a collection of data objects and parse them into JS data. Currently I have 2 choices: - Server returns valid javascript code and then I eval it. - Server returns JSON object and then I eval the json object What is the fastest of these in Firefox? (I only care about the "parsing" performance, not server or data transfer)

  • dynamic module creation

    - by intuited
    I'd like to dynamically create a module from a dictionary, and I'm wondering if adding an element to sys.modules is really the best way to do this. EG context = { a: 1, b: 2 } import types test_context_module = types.ModuleType('TestContext', 'Module created to provide a context for tests') test_context_module.__dict__.update(context) import sys sys.modules['TestContext'] = test_context_module My immediate goal in this regard is to be able to provide a context for timing test execution: import timeit timeit.Timer('a + b', 'from TestContext import *') It seems that there are other ways to do this, since the Timer constructor takes objects as well as strings. I'm still interested in learning how to do this though, since a) it has other potential applications; and b) I'm not sure exactly how to use objects with the Timer constructor; doing so may prove to be less appropriate than this approach in some circumstances. EDITS/REVELATIONS/PHOOEYS/EUREKAE: I've realized that the example code relating to running timing tests won't actually work, because import * only works at the module level, and the context in which that statement is executed is that of a function in the testit module. In other words, the globals dictionary used when executing that code is that of main, since that's where I was when I wrote the code in the interactive shell. So that rationale for figuring this out is a bit botched, but it's still a valid question. I've discovered that the code run in the first set of examples has the undesirable effect that the namespace in which the newly created module's code executes is that of the module in which it was declared, not its own module. This is like way weird, and could lead to all sorts of unexpected rattlesnakeic sketchiness. So I'm pretty sure that this is not how this sort of thing is meant to be done, if it is in fact something that the Guido doth shine upon. The similar-but-subtly-different case of dynamically loading a module from a file that is not in python's include path is quite easily accomplished using imp.load_source('NewModuleName', 'path/to/module/module_to_load.py'). This does load the module into sys.modules. However this doesn't really answer my question, because really, what if you're running python on an embedded platform with no filesystem? I'm battling a considerable case of information overload at the moment, so I could be mistaken, but there doesn't seem to be anything in the imp module that's capable of this. But the question, essentially, at this point is how to set the global (ie module) context for an object. Maybe I should ask that more specifically? And at a larger scope, how to get Python to do this while shoehorning objects into a given module?

  • Curl Wrapper Class does not return any data even though it worked previously?

    - by Scott Faisal
    We changed servers and installed all necessary software and just cannot seem to pin point what is going on. A simple CURL request does not return anything. Command Line CURL commands work just fine. We are using a wrapper for CURL utilizing streams. Do PHP streams require any out of the ordinary configuration? We are using the latest Lamp stack. This is the var_dump: object(cURL_Response)#180 (14) { ["cURL:private"]= resource(288) of type (curl) ["data_stream:private"]= object(elTempStream)#178 (1) { ["fp"]= resource(290) of type (stream) } ["request_header:private"]= NULL ["response_header:private"]= object(cURL_Headers)#179 (1) { ["headers:private"]= string(0) "" } ["response_headers:private"]= array(1) { [0]= object(cURL_Headers)#179 (1) { ["headers:private"]= string(0) "" } } ["error:private"]= string(0) "" ["errno:private"]= int(0) ["info:private"]= array(21) { ["url"]= string(21) "http://www.yahoo.com/" ["content_type"]= string(23) "text/html;charset=utf-8" ["http_code"]= int(200) ["header_size"]= int(1195) ["request_size"]= int(1153) ["filetime"]= int(-1) ["ssl_verify_result"]= int(0) ["redirect_count"]= int(1) ["total_time"]= float(0.486924) ["namelookup_time"]= float(0.003692) ["connect_time"]= float(0.005709) ["pretransfer_time"]= float(0.005714) ["size_upload"]= float(0) ["size_download"]= float(28509) ["speed_download"]= float(58549) ["speed_upload"]= float(0) ["download_content_length"]= float(211) ["upload_content_length"]= float(0) ["starttransfer_time"]= float(0.149365) ["redirect_time"]= float(0.312743) ["request_header"]= string(973) "GET / HTTP/1.0 User-Agent: cURL_ClientBase (PHP v/5.2.6-1+lenny4) Host: www.yahoo.com Accept: / Accept-Encoding: gzip, deflate, compress Referer: http://yahoo.com Cookie: B=e5iber15t7u05&b=3&s=ie; fpc_s=d=GGX6WCTIR29HWsjgLxFejKc_YJWxRqm3jYdEd6lu7W5ophpuAHBm6JGtNvhv97anG4VtaIMHQBPg3JAMOZGq59Lz_tRn_TFXgUT8T_at5HdCktVJLycy&v=2; fpt=d=nt1OT7HPe9wVIkHbMkpzQOgbP3.mQ3o1SPX7k5ztrFrWeeSWK5IgQooRY.8KtTeRMiaSEZ0kv3sO1MWtEsAzjVlRCDAZBoxqOs17v6PaZbPRqmDc92ivoMia.CqjufRs4_guOO4AyhRZ7_ml8rzxFrYeexpR2jLN0oPMyEWT0nbEf6Sdf._Bkh0HMfmI7KBnEx5uZBEEmV.wTfGRLG7zSd9sA4itOFv.r6AjP39CnogSn7NTJnqg_kEcKoiCM.lR5w_MqMc8IgWMBgSAZZgGEZpfmvxlQGnUzPwNh2pSpTe2wxFS3v1zPopDgoo2VsO3uzeyA3A_j7Hlk1P8T08DHbfr6ApDMUcr7d0QIt4pGYIxVV45XzfgpT7mgUdMei6VZrD9ozVQF0oqxrs1Ufri.XzPdB3NdQ--&v=1; fpc=d=sRPCfUfBTW96.RGiQn4hSkfi3p7WnPCAqYl5YoHecI7zjg7gH7PolscoPcq1Esm8dR.Rg1.AbQCpo2WBPXn1St96PpcjeCC.pj2.Upb3mKSRQkYPIVP1vQcL9nL7J8s9Z0VIXjiBFgSUcxyzDeUdP4us2YbVO3PbaVIwaIEfFsX3WI7YgiTbkrTGtwnFgoSYq6l8tnw-&v=2" } ["info_flagged:private"]= array(20) { [1048577]= string(21) "http://www.yahoo.com/" [2097154]= int(200) [2097166]= int(-1) [3145731]= float(0.486924) [3145732]= float(0.003692) [3145733]= float(0.005709) [3145734]= float(0.005714) [3145745]= float(0.149365) [3145747]= float(0.312743) [3145735]= float(0) [3145736]= float(28509) [3145737]= float(58549) [3145738]= float(0) [2097163]= int(1195) [2]= string(973) "GET / HTTP/1.0 User-Agent: cURL_ClientBase (PHP v/5.2.6-1+lenny4) Host: www.yahoo.com Accept: / Accept-Encoding: gzip, deflate, compress Referer: http://yahoo.com Cookie: B=e5iber15t7u05&b=3&s=ie; fpc_s=d=GGX6WCTIR29HWsjgLxFejKc_YJWxRqm3jYdEd6lu7W5ophpuAHBm6JGtNvhv97anG4VtaIMHQBPg3JAMOZGq59Lz_tRn_TFXgUT8T_at5HdCktVJLycy&v=2; fpt=d=nt1OT7HPe9wVIkHbMkpzQOgbP3.mQ3o1SPX7k5ztrFrWeeSWK5IgQooRY.8KtTeRMiaSEZ0kv3sO1MWtEsAzjVlRCDAZBoxqOs17v6PaZbPRqmDc92ivoMia.CqjufRs4_guOO4AyhRZ7_ml8rzxFrYeexpR2jLN0oPMyEWT0nbEf6Sdf._Bkh0HMfmI7KBnEx5uZBEEmV.wTfGRLG7zSd9sA4itOFv.r6AjP39CnogSn7NTJnqg_kEcKoiCM.lR5w_MqMc8IgWMBgSAZZgGEZpfmvxlQGnUzPwNh2pSpTe2wxFS3v1zPopDgoo2VsO3uzeyA3A_j7Hlk1P8T08DHbfr6ApDMUcr7d0QIt4pGYIxVV45XzfgpT7mgUdMei6VZrD9ozVQF0oqxrs1Ufri.XzPdB3NdQ--&v=1; fpc=d=sRPCfUfBTW96.RGiQn4hSkfi3p7WnPCAqYl5YoHecI7zjg7gH7PolscoPcq1Esm8dR.Rg1.AbQCpo2WBPXn1St96PpcjeCC.pj2.Upb3mKSRQkYPIVP1vQcL9nL7J8s9Z0VIXjiBFgSUcxyzDeUdP4us2YbVO3PbaVIwaIEfFsX3WI7YgiTbkrTGtwnFgoSYq6l8tnw-&v=2" [2097164]= int(1153) [2097165]= int(0) [3145743]= float(211) [3145744]= float(0) [1048594]= string(23) "text/html;charset=utf-8" } ["request_url:private"]= string(16) "http://yahoo.com" ["response_url:private"]= string(21) "http://www.yahoo.com/" ["status_code:private"]= int(200) ["cookies:private"]= array(0) { } ["request_headers"]= string(973) "GET / HTTP/1.0 User-Agent: cURL_ClientBase (PHP v/5.2.6-1+lenny4) Host: www.yahoo.com Accept: / Accept-Encoding: gzip, deflate, compress Referer: http://yahoo.com Cookie: B=e5iber15t7u05&b=3&s=ie; fpc_s=d=GGX6WCTIR29HWsjgLxFejKc_YJWxRqm3jYdEd6lu7W5ophpuAHBm6JGtNvhv97anG4VtaIMHQBPg3JAMOZGq59Lz_tRn_TFXgUT8T_at5HdCktVJLycy&v=2; fpt=d=nt1OT7HPe9wVIkHbMkpzQOgbP3.mQ3o1SPX7k5ztrFrWeeSWK5IgQooRY.8KtTeRMiaSEZ0kv3sO1MWtEsAzjVlRCDAZBoxqOs17v6PaZbPRqmDc92ivoMia.CqjufRs4_guOO4AyhRZ7_ml8rzxFrYeexpR2jLN0oPMyEWT0nbEf6Sdf._Bkh0HMfmI7KBnEx5uZBEEmV.wTfGRLG7zSd9sA4itOFv.r6AjP39CnogSn7NTJnqg_kEcKoiCM.lR5w_MqMc8IgWMBgSAZZgGEZpfmvxlQGnUzPwNh2pSpTe2wxFS3v1zPopDgoo2VsO3uzeyA3A_j7Hlk1P8T08DHbfr6ApDMUcr7d0QIt4pGYIxVV45XzfgpT7mgUdMei6VZrD9ozVQF0oqxrs1Ufri.XzPdB3NdQ--&v=1; fpc=d=sRPCfUfBTW96.RGiQn4hSkfi3p7WnPCAqYl5YoHecI7zjg7gH7PolscoPcq1Esm8dR.Rg1.AbQCpo2WBPXn1St96PpcjeCC.pj2.Upb3mKSRQkYPIVP1vQcL9nL7J8s9Z0VIXjiBFgSUcxyzDeUdP4us2YbVO3PbaVIwaIEfFsX3WI7YgiTbkrTGtwnFgoSYq6l8tnw-&v=2" }

  • understanding z buffer formates direct x

    - by numerical25
    A z buffer is just a 3d array that shows what object should be written in front of another object. each element in the array represents a pixel that holds a value from 0.0 to 1.0. My question is if that is all a z buffer does, then why are some buffers 24bit, 32bit, and 16 bit ??

  • polymorphism and interfaces

    - by mixm
    if i have two classes x and y, both extend class w. and x implementing interface z. if i have methods doSomething(w object) and doSomething(x object), what would happen if i call doSomething(x)? edit: im implementing this on java, more specifically on android. im asking this because some classes which implement a specific interface mostly does the same thing when doSomething() is called. but there are special cases which i would like to single out.

  • jQuery, Quotes, characters etc are breaking my JSON

    - by nobosh
    I'm using json2.js to create a JSON object which JQUERY posts to the Server. The object looks like: [{"locationID":"16","locationDesc":"XXXX"}, {"locationID":"111","locationDesc":"XXXX"}, {"locationID":"12","locationDesc":"XXXX"}, {"locationID":"11","locationDesc":"XXXX"}] Problem here is that XXXX sometimes contains quotes like "we're'" etc.... How should I handle this? Do you I escape somewhere or encode in some way? Thanks

  • Instance caching in Objective C

    - by zoul
    Hello! I want to cache the instances of a certain class. The class keeps a dictionary of all its instances and when somebody requests a new instance, the class tries to satisfy the request from the cache first. There is a small problem with memory management though: The dictionary cache retains the inserted objects, so that they never get deallocated. I do want them to get deallocated, so that I had to overload the release method and when the retain count drops to one, I can remove the instance from cache and let it get deallocated. This works, but I am not comfortable mucking around the release method and find the solution overly complicated. I thought I could use some hashing class that does not retain the objects it stores. Is there such? The idea is that when the last user of a certain instance releases it, the instance would automatically disappear from the cache. NSHashTable seems to be what I am looking for, but the documentation talks about “supporting weak relationships in a garbage-collected environment.” Does it also work without garbage collection? Clarification: I cannot afford to keep the instances in memory unless somebody really needs them, that is why I want to purge the instance from the cache when the last “real” user releases it. Better solution: This was on the iPhone, I wanted to cache some textures and on the other hand I wanted to free them from memory as soon as the last real holder released them. The easier way to code this is through another class (let’s call it TextureManager). This class manages the texture instances and caches them, so that subsequent calls for texture with the same name are served from the cache. There is no need to purge the cache immediately as the last user releases the texture. We can simply keep the texture cached in memory and when the device gets short on memory, we receive the low memory warning and can purge the cache. This is a better solution, because the caching stuff does not pollute the Texture class, we do not have to mess with release and there is even a higher chance for cache hits. The TextureManager can be abstracted into a ResourceManager, so that it can cache other data, not only textures.

  • C#: My callback function gets called twice for every Sent Request

    - by Madi D.
    I've Got a program that uploads/downloads files into an online server,Has a callback to report progress and log it into a textfile, The program is built with the following structure: public void Upload(string source, string destination) { //Object containing Source and destination to pass to the threaded function KeyValuePair<string, string> file = new KeyValuePair<string, string>(source, destination); //Threading to make sure no blocking happens after calling upload Function Thread t = new Thread(new ParameterizedThreadStart(amazonHandler.TUpload)); t.Start(file); } private void TUpload(object fileInfo) { KeyValuePair<string, string> file = (KeyValuePair<string, string>)fileInfo; /* Some Magic goes here,Checking The file and Authorizing Upload */ var ftiObject = new FtiObject () { FileNameOnHDD = file.Key, DestinationPath = file.Value, //Has more data used for calculations. }; //Threading to make sure progress gets callback gets called. Thread t = new Thread(new ParameterizedThreadStart(amazonHandler.UploadOP)); t.Start(ftiObject); //Signal used to stop progress untill uploadCompleted is called. uploadChunkDoneSignal.WaitOne(); /* Some Extra Code */ } private void UploadOP(object ftiSentObject) { FtiObject ftiObject = (FtiObject)ftiSentObject; /* Some useless code to create the uri and prepare the ftiObject. */ // webClient.UploadFileAsync will open a thread that // will upload the file and report // progress/complete using registered callback functions. webClient.UploadFileAsync(uri, "PUT", ftiObject.FileNameOnHDD, ftiObject); } I got a callback that is registered to the Webclient's UploadProgressChanged event , however it is getting called twice per sent request. void UploadProgressCallback(object sender, UploadProgressChangedEventArgs e) { FtiObject ftiObject = (FtiObject )e.UserState; Logger.log(ftiObject.FileNameOnHDD, (double)e.BytesSent ,e.TotalBytesToSend); } Log Output: Filename: C:\Text1.txt Uploaded:1024 TotalFileSize: 665241 Filename: C:\Text1.txt Uploaded:1024 TotalFileSize: 665241 Filename: C:\Text1.txt Uploaded:2048 TotalFileSize: 665241 Filename: C:\Text1.txt Uploaded:2048 TotalFileSize: 665241 Filename: C:\Text1.txt Uploaded:3072 TotalFileSize: 665241 Filename: C:\Text1.txt Uploaded:3072 TotalFileSize: 665241 Etc... I am watching the Network Traffic using a watcher, and only 1 request is being sent. Some how i cant Figure out why the callback is being called twice, my doubt was that the callback is getting fired by each thread opened(the main Upload , and TUpload), however i dont know how to test if thats the cause. Note: The reason behind the many /**/ Comments is to indicate that the functions do more than just opening threads, and threading is being used to make sure no blocking occurs (there a couple of "Signal.WaitOne()" around the code for synchronization)

I'm writing a console app and not a web-service so there is no Context.Request to parse the URL for me. I know that it's pretty easy to crack the query string myself but I'd rather use a FCL function is if exists.

  • Using Core Data Concurrently and Reliably

    - by John Topley
    I'm building my first iOS app, which in theory should be pretty straightforward but I'm having difficulty making it sufficiently bulletproof for me to feel confident submitting it to the App Store. Briefly, the main screen has a table view, upon selecting a row it segues to another table view that displays information relevant for the selected row in a master-detail fashion. The underlying data is retrieved as JSON data from a web service once a day and then cached in a Core Data store. The data previous to that day is deleted to stop the SQLite database file from growing indefinitely. All data persistence operations are performed using Core Data, with an NSFetchedResultsController underpinning the detail table view. The problem I am seeing is that if you switch quickly between the master and detail screens several times whilst fresh data is being retrieved, parsed and saved, the app freezes or crashes completely. There seems to be some sort of race condition, maybe due to Core Data importing data in the background whilst the main thread is trying to perform a fetch, but I'm speculating. I've had trouble capturing any meaningful crash information, usually it's a SIGSEGV deep in the Core Data stack. The table below shows the actual order of events that happen when the detail table view controller is loaded: Main Thread Background Thread viewDidLoad Get JSON data (using AFNetworking) Create child NSManagedObjectContext (MOC) Parse JSON data Insert managed objects in child MOC Save child MOC Post import completion notification Receive import completion notification Save parent MOC Perform fetch and reload table view Delete old managed objects in child MOC Save child MOC Post deletion completion notification Receive deletion completion notification Save parent MOC Once the AFNetworking completion block is triggered when the JSON data has arrived, a nested NSManagedObjectContext is created and passed to an "importer" object that parses the JSON data and saves the objects to the Core Data store. The importer executes using the new performBlock method introduced in iOS 5: NSManagedObjectContext *child = [[NSManagedObjectContext alloc] initWithConcurrencyType:NSPrivateQueueConcurrencyType]; [child setParentContext:self.managedObjectContext]; [child performBlock:^{ // Create importer instance, passing it the child MOC... }]; The importer object observes its own MOC's NSManagedObjectContextDidSaveNotification and then posts its own notification which is observed by the detail table view controller. When this notification is posted the table view controller performs a save on its own (parent) MOC. I use the same basic pattern with a "deleter" object for deleting the old data after the new data for the day has been imported. This occurs asynchronously after the new data has been fetched by the fetched results controller and the detail table view has been reloaded. One thing I am not doing is observing any merge notifications or locking any of the managed object contexts or the persistent store coordinator. Is this something I should be doing? I'm a bit unsure how to architect this all correctly so would appreciate any advice.

  • How to (simply) create new service objects in java jax-ws webservices?

    - by cibercitizen1
    Is it possible in jax-ws to have a webmethod that creates a new object (of a service class) and returns a reference to it to the client caller (for the client, it's a remote reference) so that the client and this new service object maintain a session? (Therefore each client is served by a different instance). Schematically: client server o:Session -------- -------- ---------- s = server.access() ------------------> o = new Session() return o <--- o.doSomething() ----------------------------------------------> make it <--- o.doMore() --------------------------------------------------> make it <---

  • Design pattern for adding / removing elements

    - by de3
    Wikipedia's definition for Iterator pattern design: the Iterator pattern is a design pattern in which iterators are used to access the elements of an aggregate object sequentially without exposing its underlying implementation. Iterator interface in java provides the following methods hasNext() next() remove() Is there a pattern design, or a java interface for inserting / deleting elements, and getting length of the aggregate object, in addition to iterating them? I know remove() is an optional method that can be used once per call to next(), but I am implementing a circular FIFO array and need a method delete() independent of iterator's next().
