• How to search for duplicate values in a huge text file having around Half Million records

  - by Shibu

  I have an input txt file which has data in the form of records (each row is a record and represents more or less like a DB table) and I need to find for duplicate values. For example: Rec1: ACCOUNT_NBR_1*NAME_1*VALUE_1 Rec2: ACCOUNT_NBR_2*NAME_2*VALUE_2 Rec3: ACCOUNT_NBR_1*NAME_3*VALUE_3 In the above set, the Rec1 and Rec2 are considered to be duplicates as the ACCOUNT NUMBERS are same(ACCOUNT_NBR1). Note: The input file shown above is a delimiter type file (the delimiter being *) however the file type can also be a fixed length file where each column starts and ends with a specified positions. I am currently doing this with the following logic: Loop thru each ACCOUNT NUMBER Loop thru each line of the txt file and record and check if this is repeated. If repeated record the same in a hashtable. End End And I am using 'Pattern' & 'BufferedReader' java API's to perform the above task. But since it is taking a long time, I would like to know a better way of handling it. Thanks, Shibu

• Developing and deploying games for Windows, Mac (& Linux)

  - by nornagon

  I want to write games that run on all the major platforms. I also want people to be able to play them by downloading a file and double clicking it. That means a single .exe/.app file. I'm happy to use OpenGL directly for graphics. What I don't know how to do is show a window, handle mouse/keyboard input and play sounds in a cross-platform manner. I don't really mind what the underlying language is, as long as it isn't C++ or Java. C#, Ruby or Python would be preferable, in that order :) Please, SO, save me from having to write Flash games!

• Flush() not working in drupal

  - by fawad

  I'm trying to post data from one node to another. The other node contains the for loop which iterates for long time and finally generates the table. I want to display the result after each iteration. I have tried to put "flush();" but it is not working. What should i do to display each iteration result on the node page? Note: If i do it with ob_flush() it works but it then starts printing data above the header which is not suitable. I want all the data inside the node.

• C++: retrieve map values and insert into second map

  - by donalmg

  Hi, I have one map within one header file class: class One { // code typedef map<string, int> MapStrToInt inline MapStrToInt& GetDetails(unsigned long index) { return pData[index]; } // populate pData.... private: MapStrToInt *pData; }; And a second class which implements another map and wants to get the first 10 details from the class One's map. class Two { // code One::MapStrToInt pDataTen; int function1() { for (int i =0; i < 10; i ++) { One::MapStrToInt * pMap = &(One::GetDetails(i)); pDataTen.insert(pair<string, int>(pMap->first,pMap->second)); } } When I compile this, it states that pMap: has no member named 'first' has no member named 'second' Any suggestions? Thanks..

• Python: How to get a value of datetime.today() that is "timezone aware"?

  - by mindthief

  Hi, I am trying to subtract one date value from the value of datetime.today() to calculate how long ago something was. But it complains: TypeError: can't subtract offset-naive and offset-aware datetimes The value datetime.today() doesn't seem to be "timezone aware", while my other date value is. How do I get a value of datetime.today() that is timezone aware? Right now it's giving me the time in local time, which happens to be PST, i.e. UTC-8hrs. Worst case, is there a way I can manually enter a timezone value into the datetime object returned by datetime.today() and set it to UTC-8? Of course, the ideal solution would be for it to automatically know the timezone. Thanks!

• Inconsistent values in network switch throughput values

  - by Marcus Hughes

  Quite simple, I have a network switch with SNMP, and need to calculate the throughput of the switch port, so simply I use ifOutOctets. We transfer a file which is 145MB and if we use the total from the start, subtracted from the value at the end then the value is : 158901842 I simply can't get the value to match, or be anything similar to what the real transfer is. I understand that there may be excess traffic etc but I just can't get it to be anywhere similar (the server being tested has no traffic when this is not running) We have tried for a long time and suspect there may be an issue with the recording on the HP switch, do you have any suggestions, or how should we be calculating it? Thanks a lot in advance We have a HP ProCurve 1810G on 2.2

• how to play an encrypted file in Android.

  - by user306517

  I need to be able to play an encrypted file in Android. The file is AAC. The only way I can see to do this is either: decrypt the file to internal private storage and point the player at that file to play, or decrypt & decode the file to pcm and feed it to an AudioTrack. 1 isn't great because it takes a long time to do that. 2 isn't great either because I don't know how I can take advantage of the HW decoder to do this. Any ideas? tia.

• Tracking/Counting Word Frequency

  - by Joel Martinez

  I'd like to get some community consensus on a good design to be able to store and query word frequency counts. I'm building an application in which I have to parse text inputs and store how many times a word has appeared (over time). So given the following inputs: "To Kill a Mocking Bird" "Mocking a piano player" Would store the following values: Word Count ------------- To 1 Kill 1 A 2 Mocking 2 Bird 1 Piano 1 Player 1 And later be able to quickly query for the count value of a given arbitrary word. My current plan is to simply store the words and counts in a database, and rely on caching word count values ... But I suspect that I won't get enough cache hits to make this a viable solution long term. Can anyone suggest algorithms, or data structures, or any other idea that might make this a well-performing solution?

• How do you convert date taken from a bash script to milliseconds in java program?

  - by Matt Pascoe

  I am writing a piece of code in java that needs to take a time sent from a bash script and parse the time to milliseconds. When I check the millisecond conversion on the date everything is correct except for the month I have sent which is January instead of March. Here is the variable I create in the bash script, which later in the script I pass to the java program: TIME=`date +%m%d%Y_%H:%M:%S` Here is the java code which parses the time to milliseconds: String dt = "${scriptstart}"; java.text.SimpleDateFormat scriptStart = new java.text.SimpleDateFormat("MMDDyyyy_HH:mm:ss"); long start = scriptStart.parse(dt).getTime(); The goal of this statement is to find the elapsed time between the start of the script and the current system time. To troubleshoot this I printed out the two: System Time = 1269898069496 (converted = Mon Mar 29 2010 16:27:49 GMT-0500 (Central Daylight Time)) Script Start = 03292010_16:27:45 Script Start in Milli = 1264804065000 (Converted = Fri Jan 29 2010 16:27:45 GMT-0600 (Central Standard Time))

• Clone a lua state

  - by hbxfnzwpf

  Recently, I have encountered many difficulties when I was developing using C++ and Lua. My situation is: for some reason, there can be thousands of Lua-states in my C++ program. But these states should be same just after initialization. Of course, I can do luaL_loadlibs() and lua_loadfile() for each state, but that is pretty heavy(in fact, it takes a rather long time for me even just initial one state). So, I am wondering the following schema: What about keeping a separate Lua-state(the only state that has to be initialized) which is then cloned for other Lua-states, is that possible?

• Pattern for iPhone background loading during init?

  - by Rob S.

  Hi everyone, I'm currently kicking off a background thread to do some REST queries in my app delegate's didFinishLaunchingWithOptions. This thread creates some objects and populates the model as the rest of the app continues to load (because I don't block, and didFinishLaunchingWithOptions returns YES). I also put up a loading UIViewController 'on top' of the main view that I tear down after the background initialization is complete. My problem is that I need to notify the first view (call it the Home view) that the model is ready, and that it should populate itself. The trick is that the background download could have finished before Home.viewDidAppear is called, or any of the other Home.initX methods. I'm having difficulty synchronizing all of this and I've thought about it long enough that it feels like I'm barking up the wrong tree. Are there any patterns here for this sort of thing? I'm sure other apps start by performing lengthy operations with loading screens :) Thanks!

• How does DateTime.Now.Tick exactly work?

  - by Roflcoptr

  In my application I generate files at random opportunities. To ensure a unique naming, I tried to use the nano seconds since 1.1.1970: long time = DateTime.Now.Ticks; String fileName = Convert.ToString(time); Console.WriteLine(fileName); Now I observed something weird. Why is the output like that? I mean why are the last 4 numbers always the same? I can use this as a filename, that is not the problem, but I'm just wondering about it. 634292263478068039 634292263512888039 634292263541368039 634292263603448039 634292263680078039

• Ideal timeout period for dns lookup

  - by railscoder

  In my rails app i do a nslookup using a ruby library resolv. If the site like dgdfgdfgdfg.com is entered its talking too long to resolve. in some instance like 20 sec.(mostly for non-existent sites) Because it cause the application to slowdown. So i though of introducing a timeout period for the dns lookup. What will be the ideal timeout period for the dns lookup so that resolution of actual site doesnt fail. will something like 10 sec will be fine?

• Charaters with jquery json

  - by Mikk

  Hi everyone, I'm using jquery $.getJSON to retrieve list of cities. Everything works fine, but I'm from Estonia (probably most of you don't know much about this country =D) and we are using some characters like õ, ü. ä, ö. When I pass letters like this to callback function, I keep getting empty strings. I've tried to base64 encode(server-side)-decode(jquery base64 plugin) strings (i thought it was a good idea as long as I can compress pages with php, so I don't have to worry about bandwidth), but in this way I end up with some random chinese symbols. What would be the best workaround for this problem. Thank you.

• WYSIWYG editor that is intergrated with Ruby on Rails

  - by atmorell

  Hello, I have worked with Ruby on Rails for the last four years. So far I have used textmate for writing the code. This is working great as long as I don't need to do any decent presentation. I was wondering if there is any WYSIWYG editor out there that can intergrate with Rails. Something like Dreamweaver with the ability to browse Objects etc. If I have opened the _show.erb I create a div and selete @user.email. etc. Any suggestions?

• Where do I place the launch image "Default.png" in my iPhone app's project directory?

  - by Dr Dork

  In the Apple documentation, it says... iPhone OS looks for a Default.png file, located in the top level of the application bundle. but I'm having a hard time figuring out how to get the image in that location in the bundle (I'm new to all this). I'm assuming my image will end up in the right place in the bundle when I compile it so long as I add it to the project correctly and place it in the right location in the project directory. My questions are... Where in my project directory should I place the "Default.png" image? Do I need add it to the project through Xcode? If so, how? Thanks so much in advance for all your help! I'm going to continue researching this question right now.

• How to convert from integer to unsigned char in C, given integers larger than 256?

  - by Alf_InPogform

  As part of my CS course I've been given some functions to use. One of these functions takes a pointer to unsigned chars to write some data to a file (I have to use this function, so I can't just make my own purpose built function that works differently BTW). I need to write an array of integers whose values can be up to 4095 using this function (that only takes unsigned chars). However am I right in thinking that an unsigned char can only have a max value of 256 because it is 1 byte long? I therefore need to use 4 unsigned chars for every integer? But casting doesn't seem to work with larger values for the integer. Does anyone have any idea how best to convert an array of integers to unsigned chars?

• Many Associations Leading to Slow Query

  - by Joey Cadle

  I currently have a database that has a lot of many to many associations. I have services which have many variations which have many staff who can perform the variation who then have details on themselves like name, role, etc... At 10 services with 3 variations each and up to 4 out of 20 staff attached to each service even doing something as getting all variations and the staff associated with them takes 4s. Is there a way I can reduce these queries that take a while to process? I've cut down the queries by doing eager loading in my DBM to reduce the problems that arise from 1+N issues, but still 4s is a long query for just a testing stage. Is there a structure out there that would help make such nested many to many associations much quicker to select? Maybe combining everything past the service level into a single table with a 'TYPE' column ?? I'm just not knowledgable enough to know the solution that turns this 4s query into a 300MS query... Any suggestions would be helpful.

• display full path of file in status bar

  - by robUK

  Hello GNU Emacs 23.1.1 I am wondering is there a way to display the path of the file in the status bar, instead of just the filename. I have to open many files in many directories, and sometimes I forget what directory they are in. Just easier to display the some of the path in the status bar if that is possible. Sometimes my directory paths are very long. for example /projects/clientserver/trunk/src/client/client.c like this in the status bar, just display the last two directories. /src/client/client.c Many thanks for any suggestions,

• Is a PHP-only "cache engine" ever worth it?

  - by adsads

  I wrote a rather small skeleton for my web apps and thought that I would also add a small cache for it. It is rather simple: If the current page exists as a file in the cache and the file isn't too old, read it out and exit instead of rebuilding the page If the current page isn't cached/outdated recalc the page and save it However, the bad thing about it is: My performance tests with a page that receives 40 relatively long posts via a MySQL query said that with using the cache, it took even longer to handle a single request (1000 tests each) How can that happen? Should I just remove the complete raw-PHP cache and relieve on the availability of some PHP cache like memcached or so?

• How to simplify my code... 2D array in Objective C...?

  - by Tattat

  self.myArray = [NSArray arrayWithObjects: [NSArray arrayWithObjects: [self d], [self generateMySecretObject],nil], [NSArray arrayWithObjects: [self generateMySecretObject], [self generateMySecretObject],nil],nil]; for (int k=0; k<[self.myArray count]; k++) { for(int s = 0; s<[[self.myArray objectAtIndex:k] count]; s++){ [[[self.myArray objectAtIndex:k] objectAtIndex:s] setAttribute:[self generateSecertAttribute]]; } } As you can see this is a simple 2*2 array, but it takes me lots of code to assign the NSArray in very first place, because I found that the NSArray can't assign the size at very beginning. Also, I want to set attribute one by one. I can't think of if my array change to 10*10. How long it could be. So, I hope you guys can give me some suggestions on shorten the code, and more readable. thz

• Sbyte[] vs byte[][] using methods

  - by blgnklc

  It is written byte[][] getImagesForFields(java.lang.String[] fieldnames) Gets an array of images for the given fields. On the other hand, as long as I use the method in the web application project built on asp.net 2.o using c#; the provided web method declared above, returns sbyte; Have a look my code below; formClearanceService.openSession(imageServiceUser); formClearanceService.prepareInstance(formId); byte[][] fieldImagesList = formClearanceService.getImagesForFields(fieldNames); formClearanceService.closeSession(); thus I get the following error: Cannot implicitly convert type 'sbyte[]' to 'byte[][]' So now, 1- should I ask the web service provider what is going on? or 2- any other way that can use the sbyte as I was suppose to use byte[][] like following using: byte[] ssss = fieldImagesList [0]..
