• Java deserialization speed

  - by celicni

  I am writing a Java application that among other things needs to read a dictionary text file (each line is one word) and store it in a HashSet. Each time I start the application this same file is being read all over again (6 Megabytes unicode file). That seemed expensive, so I decided to serialize resulting HashSet and store it to a binary file. I expected my application to run faster after this. Instead it got slower: from ~2,5 seconds before to ~5 seconds after serialization. Is this expected result? I thought that in similar cases serialization should increase speed.

• What can you do in ::OnInitDialog() Visual Studio 2008 C++

  - by flirishman

  What can or cannot you do in ::OnInitDialog() Visual Studio 2008 C++ I would like to write out some text on the dialog at the dialog startup. If I put the same code in a PUSH-BUTTON OnBnClicked it works. If I put it in the OnInit, it does not give me the text on the screen. I'm assuming at the OnInit, my dialog box is not completely up, so I cannot write on it? CRect drawRect; drawRect.left = 00; // Shifts text to right drawRect.right = 300; drawRect.top = 00; // How Far Down drawRect.bottom = 300; // Clear out any previous name CString strBlank = "Book Name"; SSTextOut(this->GetDC(), strBlank, &drawRect, DT_LEFT); The function I am writing to is described in http://www.codeproject.com/KB/GDI/SSTextOut.aspx

• conditional beginReceive

  - by sbenderli

  I am writing a client program that uses Sockets. I would like the client to receive asyncronously UNLESS it is expecting a response, in which case I would like to receive syncronously. My current problem is that because I have to make a call to socket.BeginReceive which waits until there's data on the buffer, the async call always happens prior to the sync call.. How could I temporarily stop BeginReceive from executing? Is there a way to call EndReceive and then once I am done receiving syncronously, I can continue to receive asnycronously?

• sending an url but staying on the same page ( php, codeigniter, javascript )

  - by user1776815

  this is my situation. I'm writing an webinterface in codeigniter to send commands to a virtual server. these commands are passed through the browser in an url. example : http://server.com/TgtSendIRCommand?id=UM-02&code=KEY_UP this server then takes action and the web interface refreshes the screenshot. i just want to have a bunch of links in html that send this command to the browser. But if i click the links, the user has to stay on the same page. So the command is sended but there is no other interaction. i am using codeigniter. Any suggestions ?

• RESTful enums. string or Id?

  - by GazTheDestroyer

  I have a RESTful service that exposes enums. Should I expose them as localised strings, or plain integers? My leaning is toward integers for easy conversion at the service end, but in that case the client needs to grab a list of localised strings from somewhere in order to know what the enums mean. Am I just creating extra steps for nothing? There seems to be little information I can find about which is commonly done in RESTful APIs. EDIT: OK. Let's say I'm writing a website that stores information about people's pets. I could have an AnimalType enum 0 Dog 1 Cat 2 Rabbit etc. When people grab a particular pet resource, say /pets/1, I can either provide a meaningful localised string for the animal type, or just provide the ID and force them to do another look up via a /pets/types resource. Or should I provide both?

• php: possible to convert array of numbers to 'from' and 'to' pairs where consecutive?

  - by Haroldo

  I have an array of timestamps referring to the days when a holiday home is booked. each timestamp is a round day. I want to turn this into an array of 'begins' and 'ends' pairs for consecutive dates Are there any php functions I should be aware of for writing this function? Or does anyone have any pointers for this kind of thing? thanks! edit: example array: Array ( [0] => 1273536000 [1] => 1273622400 [2] => 1273708800 [3] => 1273795200 [4] => 1273881600 [5] => 1273968000 [6] => 1274054400 [7] => 1274140800 [8] => 1274227200 ) where a day = 86400 (seconds)

• If I write a framework that gets information from the Internet, should I make a degelate or use blocks?

  - by Time Machine

  Say I'm writing a publicly available framework for the Vimeo API. This framework needs to get information from the Internet. Because this can take some time, I need to use threadin to prevent the UI from hanging. Foundation uses delegates for this, like NSURLConnectionDelegate. However, Game Kit uses blocks as callback functions. What is the recommended way of doing this? I know blocks aren't supported in standard GCC versions, but they require less, much less code for the one that uses my framework. Delegates, on the other hand, are real methods and when protocols are used, I'm sure the methods are implemented. Thanks.

• Any Way to Use a Join in a Lambda Where() on a Table<>?

  - by lush

  I'm in my first couple of days using Linq in C#, and I'm curious to know if there is a more concise way of writing the following. MyEntities db = new MyEntities(ConnString); var q = from a in db.TableA join b in db.TableB on a.SomeFieldID equals b.SomeFieldID where (a.UserID == CurrentUser && b.MyField == Convert.ToInt32(MyDropDownList.SelectedValue)) select new { a, b }; if(q.Any()) { //snip } I know that if I were to want to check the existence of a value in the field of a single table, I could just use the following: if(db.TableA.Where(u => u.UserID == CurrentUser).Any()) { //snip } But I'm curious to know if there is a way to do the lambda technique, but where it would satisfy the first technique's conditions across those two tables. Sorry for any mistakes or clarity, I'll edit as necessary. Thanks in advance.

• .NET DB Query Without Allocations?

  - by Michael Covelli

  I have been given the task of re-writing some libraries written in C# so that there are no allocations once startup is completed. I just got to one project that does some DB queries over an OdbcConnection every 30 seconds. I've always just used .ExecuteReader() which creates an OdbcDataReader. Is there any pattern (like the SocketAsyncEventArgs socket pattern) that lets you re-use your own OdbcDataReader? Or some other clever way to avoid allocations? I haven't bothered to learn LINQ since all the dbs at work are Oracle based and the last I checked, there was no official Linq To Oracle provider. But if there's a way to do this in Linq, I could use one of the third-party ones.

• How to re-open a closed file descriptor

  - by chaitu

  I have a scenario where i created pipe for communication between two child and parent. Parent writes (using write function)data to the pipe and closes the respective file descriptor. The problem is when i want to write data again to the pipe, the write function is returning error code -1. I think its because writing end has been closed in previous iteration. Then how to open the corresponding file descriptor after it has been closed once. I tried using open() function which requires path to some file as arguement. But i am not using any files in my application. I have simple file descriptors (int arr[2]). Is it possible to achieve above scenario with pipes????

• Cannot convert []string to []interface {}

  - by karlrh

  I'm writing some code, and I need it to catch the arguments and pass them through fmt.Println (I want its default behaviour, to write arguments separated by spaces and followed by a newline). However it takes []interface {} but flag.Args() returns a []string. Here's the code example package main import ( "fmt" "flag" ) func main() { flag.Parse() fmt.Println(flag.Args()...) } This returns the following error: ./example.go:10: cannot use args (type []string) as type []interface {} in function argument Is this a bug? Shouldn't fmt.Println take any array? By the way, I've also tried to do this: var args = []interface{}(flag.Args()) but I get the following error: cannot convert flag.Args() (type []string) to type []interface {} Is there a "Go" way to workaround this?

• Execute code when Eclipse workbench loads

  - by Krt_Malta

  Hi! I'm writing an Eclipse plug-in and I've bumped into an issue. Amongst others I'm creating a new custom perspective. I need to execute some code when the workbench loads. I'm using a WorkbenchAdvisor and putting the code in the initialize method. However as it is now it's not being called... Apparently I need to call this PlatformUI.createAndRunWorkbench(display, new ApplicationWorkbenchAdvisor(); but I don't know where to put this... I can't put it in the createInitialLayout of the perspective because this is only called when the perspective is created for the first time. Any ideas please? Thanks and regards, Krt_Malta

• Nesting if else statements in PHP to validate a URL

  - by John

  I'm currently writing up a function in order to validate a URL by exploding it into different parts and matching those parts with strings I've defined. This is the function I'm using so far: function validTnet($tnet_url) { $tnet_2 = "defined2"; $tnet_3 = "defined3"; $tnet_5 = "defined5"; $tnet_7 = ""; if($exp_url[2] == $tnet_2) { #show true, proceed to next validation if($exp_url[3] == $tnet_3) { #true, and next if($exp_url[5] == $tnet_5) { #true, and last if($exp_url[7] == $tnet_7) { #true, valid } } } } else { echo "failed on tnet_2"; } } For some reason I'm unable to think of the way to code (or search for the proper term) of how to break out of the if statements that are nested. What I would like to do check each part of the URL, starting with $tnet_2, and if it fails one of the checks ($tnet_2, $tnet_3, $tnet_5 or $tnet_7), output that it fails, and break out of the if statement. Is there an easy way to accomplish this using some of the code I have already?

• How to make shell output redirect (>) write while script is still running?

  - by Noio

  I wrote a short script that never terminates. This script continuously generates output that I have to check on every now and then. I'm running it on a lab computer through SSH, and redirecting the output to a file in my public_html folder on that machine. python script.py > ~/public_html/results.txt However, the results don't show up immediately when I refresh the address. The results show up when I terminate the program, but as I said, it doesn't halt by itself. Is that redirect (>) being lazy with with writing? Is there a way to continuously (or with an interval) update the results in the file? Or is it the webserver that doesn't update the file while it is still being written?

• Removing an element from an array (PHP)

  - by morpheous

  I want to remove an element from a PHP array (and shrink the array size). Just looking at the PHP docs, it seems this can be done using array_slice() and array_merge() so I am guessing (off the top of my head) that some combination of array_merge() and array_slice will work. However, array_slice() requires an index (not a key), so I'm not sure how to quickly cobble these functions together for a solution. Has anyone implemented such a function before?. I'm sure it must be only a few lines long, but I cant somehow get my head around it (its been one of those days) ... Actually, I just came up with this cheesy hack when writing up this question.... function remove_from_array(array $in, value) { return array_diff($in, (array)$value); } too ugly? or will it work (without any shocking side effects)?

• Java: howto write equals() shorter

  - by erikb

  I get headaches when I have to write nearly 10 lines of code to say 2 Objects are equal, when their type is equal and both's attribute is equal. You can easily see that in this way of writing the number of lines increase drastically with your number of attributes. public class Id implements Node { private String name; public Id(String name) { this.name = name; } public boolean equals(Object o) { if (o == null) return false; if (null == (Id) o) return false; Id i = (Id) o; if ((this.name != null && i.name == null) || (this.name == null && i.name != null)) return false; return (this.name == null && i.name == null) || this.name.equals(i.name); } }

• [C++] Passing around objects to network packet handlers ?

  - by xeross

  Hey, I've been writing a networking server for a while now in C++ and have come to the stage to start looking for a way to properly and easily handle all packets. I am so far that I can figure out what kind of packet it is, but now I need to figure out how to get the needed data to the handler functions. I had the following in mind: Have a map of function pointers with the opcode as key and the function pointer as value Have all these functions have 2 arguments, packet and ObjectAccessor ObjectAccessor class contains various functions to fetch various items such as users and alike Perhaps pass the user's guid too so we can fetch it from the objectaccessor I'd like to know the various implementations others have come up with, so please comment on this idea and reply with your own implementations. Thanks, Xeross

• [Cakephp] How to use Read()

  - by kwokwai

  Hi all, In a Controller, I got this: $this->Site1->post_id=$id; $this->set('posts', $this->Site1->read()); And when I replaced it by this line of code: $this-set('posts', $this-Site1-read('post_id', $id)); But the returned result is totally different. Is there any difference between them? Is it possible to make this two lines of code neat by re-writing it into one line of code? $this->Site1->post_id=$id; $this->set('posts', $this->Site1->read());

• Saving variables (not sessions)

  - by james.bcn

  This may be a silly question, but how do I save variables that are not specific to a particular session. An simple example of why you might want to do this would be a visitor counter - a number that increases by one each time someone visits a web page (note - I'm not actually doing that, my application is different, but that is the functionality I need). The only ways I can think of doing this are either writing the variables to a file, or putting the variables into a database. Both seem a bit inelegant. Is there a better way to to this kind of thing?

• C# Deserializing to a dictionary<string, Object>

  - by lovecraft

  I'm writing a C#/VB application to connect to a database and do stuff with the data. I was given this code to take a serialized byte array and deserialized it, which is then written to a Dictionary The line of code is: Dictionary<string, Object> DictionaryEmployee = (Dictionary<string, Object> Deserializer(byteArrayEmp)); The errors I'm getting are exceedingly unhelpful. "Only assignment, call, increment, decrement, await, and new object expressions can be used as a statement" if I mouse over Object and "Using the generic type 'System.Collections.Generic.Dictionary' requires 2 type arguments if I mouse over Dictionary.

• Are instance initializers good or bad?

  - by berry120

  I personally quite like instance initializers - I use them to assign default values to things such as collections so when writing constructors I don't have to remember to assign them the same default values each time. It seems quite elegant to me - avoids annoying NPE's popping up and avoids duplicate code. A private method doesn't seem as nice because a) it can't assign values to final fields, b) it could be run elsewhere in code and c) the method still needs to be explicitly called at the start of each constructor. However, the flip side with others I have spoken to is that they're confusing, some people reading the code might not understand what they do or when they're called and thus they could cause more problems than they solve. Are proper use of these initializers something to be encouraged or avoided? Or is it an "each to their own" case?

• Iphone Game Dev Over The Internet

  - by kernix

  Hello, I was wondering is there an easy way to communicate between iphones over the Internet(Not LAN/Bluetooth) or must there be a dedicated server in which all the iphones running an application needs to connect to? For instance, suppose I'm writing a game which works on the Internet. Once four clients joins a room, game starts. must I implement a server in which every Iphone client connects to (for instance if server was developed on Windows it could be a Service) or is there another way to address this when developing Internet-based application? Thank you
