• Design guidelines for cache mechanism

  - by Delashmate

  Hi All, I got assignment to write design for cache mechanism (this is work assignment, not homework), This is my first time writing a design document, Our program display images for doctors, and we want to reduce the parsing time of the images So we want to save the parsed data in advance (in files or inside database) Currently I have several design key ideas: Handle locks - each shared data structure should be handled, also files Test - add test to verify the data from the cache is equal to the data from the files To decouple the connection to the database- not to call directly to the database Cleanup mechanisem- to delete old files if the cahce directory exceed configurable threshold Support config file Support performance tool in the feature I will also add class diagram, data flow charts, and workflow What do you think I should add to the key ideas? Do you know good link to atricales about design? Thanks in advance, Dan

• find a specific string pattern in an array jquery

  - by Bwyss

  Apologies if this is a duplicate, but I can't seem to find the solution. I am trying to find a specific string pattern in an array. I want to find all values in data that contain 'underscore r underscore'. I then want to create a new array that contains only those keys and values. var data = ["something", "bar_r_something"]; var resultArray = new Array(); for (var i = 0; i < data.length; i++) { var bar = /_r_/; if ($.inArray(bar, data[i].length) > 0) { console.log("found _r_"); resultArray.push(data[i]); } }; I just can't seem to get that $.inArray to work, it seems to always kick out -1.

• The Truth About Flash - Apple Vs Adobe

  Every emerging technology generation seems to result in a battle of platforms and ideologies - a war between companies for the hearts, minds, dollars and loyalty of consumers for their system of choice. Memories of Microsoft's Internet Explorer finally landing the fatal blow to Netscape, or Google's meteoric rise to power over Yahoo (and the world), are now but footnotes in the history of humanities technological revolution. But no sooner are they forgotten are we plunked into the middle of another war - perhaps the most vicious yet, and the one that may just have the most impact on our...

• CoreData and UITableViewController Problem

  - by eemceebee

  Hi I have a app that works with Core Data. The data has a field with a date and I would like to show every entry of a month in a seperate section. How do I actually get the data ? I use a NSFetchedResultsController to get the data and use this : - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section { id <NSFetchedResultsSectionInfo> sectionInfo = [[_fetchedResultsController sections] objectAtIndex:section]; return [sectionInfo numberOfObjects]; } to get the rows and this : - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { MyInfoObject *info = [_fetchedResultsController objectAtIndexPath:indexPath]; } to get my actually data object. Thanks

• How to measure the time taken by C# NetworkStream.Read?

  - by publicENEMY

  I want to measure time taken for client to receive data over tcp using c#. Im using NetworkStream.Read to read 100 megabits of data that are sent using NetworkStream.Write. I set the buffer to the same size of data, so there no buffer underrun problem etc. Generally it looks like this. Stopwatch sw = new Stopwatch(); sw.Start(); stream.Read(bytes, 0, bytes.Length); sw.Stop(); The problem is, there is a possibility where the sender hasnt actually sent the data but the stopwatch is already running. how can i accurately measure the time taken to receive the data? i did try to use the time lapse of the remote pc stream.Write, but the time it took to write is extremely small. by the way, is the stopwatch is the most accurate tool for this task?

• JQuery post to php

  - by RussP

  Why is it that I can never get JQuery serialize to work properly. I guess I must be missing something. I can serialize a form data and it shows in an alert: var forminfo = $j('#frmuserinfo').serialize(); alert(forminfo); I then post to my PHP page thus: $j.ajax({ type: "POST", url: "cv-user-process.php", data: "forminfo="+forminfo, cache: false, complete: function(data) { } }); But WHENEVER (not the first time) I try to insert/update the data in the DB I only ever get 1 varaible passed: Here is my PHP script: $testit = mysql_query("UPDATE cv_usersmeta SET inputtest='".$_POST['forminfo']."' WHERE user='X'"); the data passed only ever gets the first variable. why? I think it is more the way I deal with the php but it drives me nuts and always takes me far too long to find where I am going wrong.

• PHP cors validation

  - by Brian Putt

  I have an endpoint that takes GET requests to collect data from any source that wants to send data. Is there a way to run some validation that the data is in fact coming from the sources we allowed? They enter the website url that they will be sending the data from and we generate an api key. The data is sent via a javascript file that they install onto their website. I have the Access-Control-Allow-Origin set to * as it doesn't necessarily scale to add in hundreds or more websites to that header and that in itself is a security risk as it shows anyone who wants to look at the headers who uses the script. Currently I am thinking of using the http_origin / origin referrer, but obviously that doesn't do too much

• Manually Building a Tree in CakePHP

  - by mabwi

  I'm currently working on building an application in CakePHP. There's a quite extensive existing data set that's conceptually a tree, but wasn't previously stored as one. What I mean by that, is there's no real relationship defined in the data. The problem I'm having is getting it to work correctly with the CakePHP tree behaviour. Because I have to set all the values on existing data - as opposed to Cake setting up the structure as elements are inserted - I need to understand how the lft/rght values work. So, I guess the question is: How does the structure data work, specifically the lft/rght values? How do I set it up so that the data comes out rationally, without inserting them one at a time? It's a 2 level tree, with Sections and sub-sections. Thanks for the help

• Postback of delimited text from javascript and parsing on server side

  - by Alt_Doru

  In my ASP.NET page, I have a Javascript object, like this: var args = new Object(); args.Data1 = document.getElementById("Data1").value; args.Data2 = document.getElementById("Data2").value; args.Data3 = document.getElementById("Data3").value; The object is populated on client side using user input data. I am passing the data to a C# method, through an Ajax request: someObj.AjaxRequest(argsData1 + "|" + argsData2 + "|" + argsData3) Finally, I need to obtain the data in my C# code: string data1 = [JS args.Data1] string data2 = [JS args.Data2] string data3 = [JS args.Data3] My question is what's the best solution for this? As i am concatenating bits of user input, I don't think it's best to use "|" as a delimiter. Also, it's not clear to me how to actually parse the data in my C# code to populate the three variables with the original data.

• What is the best way to sync multiple client SqlServers to one MS SqlServer 2005?

  - by user605055

  I have several client databases that use my windows application. I want to send this data for online web site. The client databases and server database structure is different because we need to add client ID column to some tables in server data base. I use this way to sync databases; use another application and use C# bulk copy with transaction to sync databases. My server database sql server is too busy and parallel task cannot be run. I work on this solution: I use triggers after update, delete, insert to save changes in one table and create sql query to send a web service to sync data. But I must send all data first! Huge data set (bigger than 16mg) I think can't use replication because the structure and primary keys are different.

• How to mimic an excel spreadsheet on a website in vb.net?

  - by user1439659

  I am building a website to capture data. I have many spreadsheets that are used for data entry or capture. Now I want to mimic these complex spreadsheets on the web forms but I am unsure of the correct control to use. Data entry must be allowed and live calculations also need to be made similar to formulas on normal excel spreadsheets. Later on the data must be captured into an SQL table. What would be the best control to use or method to mimic that functionality, albeit that the spreadsheet component is no longer available in visual studio 2010. Is it a data grid? Thanks

• Splitting up input using regular expressions in Java

  - by Joe24

  I am making a program that lets a user input a chemical for example C9H11N02. When they enter that I want to split it up into pieces so I can have it like C9, H11, N, 02. When I have it like this I want to make changes to it so I can make it C10H12N203 and then put it back together. This is what I have done so far. using the regular expression I have used I can extract the integer value, but how would I go about get C10, H11 etc..? System.out.println("Enter Data"); Scanner k = new Scanner( System.in ); String input = k.nextLine(); String reg = "\\s\\s\\s"; String [] data; data = input.split( reg ); int m = Integer.parseInt( data[0] ); int n = Integer.parseInt( data[1] );

• Querying Same Lookup Table With Multiple Columns

  - by dmaruca

  I'm a bit confused on this. I have a data table structured like this: Table: Data DataID Val 1 Value 1 2 Value 2 3 Value 3 4 Value 4 Then I have another table structured like this: Table: Table1 Col1 Col2 1 2 3 4 4 3 2 1 Both columns from Table1 point to the data in the data table. How can I get this data to show in a query? For example, a query to return this: Query: Query1 Column1 Column2 Value 1 Value 2 Value 3 Value 4 Value 4 Value 3 Value 2 Value 1 I'm familiar enough with SQL to do a join with one column, but lost beyond that. Any help is appreciated. Sample sql or a link to something to read. Thanks! PS: This is in sqlite
