• Design cache mechanism

  - by Delashmate

  Hi All, I got assignment to write design for cache mechanism, This is my first time writing a design document, Our program display images for doctors, and we wan't 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

• HTMLtags in input field

  - by megapool020

  I have a question about inserting values into an input field from my MYSQL DB. First I have a form to save data from an inputfield to the database. An extra script filters diacrits Á=&Aacute; to html code. So Állo will be saved like &Aacute;llo When I insert the data from the DB to a 'div' it shows Állo. When I insert the data into a input field it shows &Aacute;llo What am I doing wrong I use JQUERY to save data to the DB with the $.post method without pagerefresh. I also get the data from the DB with JQUERY $.post method without pagerefresh. Hope somebody can help.

• SQL Server Replication

  - by Serge

  I have a device that continuously collects data and stores it on a local database. I would like to also replicate that data to a second computer over the network every 10 seconds to ensure data reliability. Should I use transaction replication to achieve this? What if the network connection is temporarily unavailable, will the replication service automatically transmit all the backlogged data once the connection is restored? Can the computer that collects the data be SQL Server Compact or does it have to be at least Workgroup edition to be a Publisher. The second PC will run SQL Server Express and would be a subscriber. Thanks.

• give apache permission to write files to folder

  - by user1683645

  I'm trying to give www-data which is the name of the apache on my ubuntu permission to write files to folders. The entire website is in /media/root/data/ and I've got member folders containing the user specific images. apache tmp folder is set to: /media/root/data/tmp and the permission is set for www-data to read and write to it. About member folders that contain images. First off I tried giving www-data the rw permission and upload an image, but it did not work. Everything else in the site works except uploading files. How do I automaticly give apache rw permission to new member folders? And why cant I write to it?

• r -- finding difference between business days

  - by acesnap

  I have several years of data (only for business days (no weekends or holidays)) in an [r] data frame and would like to find the difference between the data on the 2nd and 5th business day of each month. So the solution needs to go thru the list, determine the 2nd and 5th business day, get the data for the corresponding dates and then find the difference. the data looks like: 1/19/1990 1.22 1/20/1990 1.25 1/23/1990 1.26 (Gap in date is weekend) ... 2/1/1990 1.34 2/2/1990 1.36 2/5/1990 1.22 (Gap in date is weekend) I have tried using dateTime() but it doesn't handicap for weekends and holidays. Any suggestions would be appreciated, thanks.

• Make a simulation using python

  - by user3727759

  I am new to programming and using python. What I am trying to do is create a simulation of a thermostat system by using python. Is there a way to create a program that I can input data, for example temperature and humidity values and then have python constantly plotting the data as I enter the values. This is to simulate a device gathering data and sending it to this program and having it being plotted. I have found ways to plot data by using matplotlib but I have not been able to find a way that I can input the data and have the plot upgrade constantly. Thanks any advise is appreciated.

• JavaScript OOP problem

  - by Danmark

  I create windows like this: var obj = document.createElement('div'); obj.className = 'window'; obj.style.width = 300 + 'px'; obj.style.height = 200 + 'px'; obj.style.left = 30 + 'px'; obj.style.top = 200 + 'px'; //and so on and what I need is to attach some data to each window. The data will be grabbed via Ajax and displayed in the windows. How should I do it so that each window hold its own unique data? I don't need to display the whole data every time and this data would need be organized before being displayed, so I can't just add it with innerHTML. I need a way to hold it somewhere else where I could easily get it and then display it with innerHTML.

• Javascript: Retrieve Object Property Names

  - by Jason

  I'm trying to write a function that needs to know the property names of an object being passed in, like so: var data = { "key1":"value1", "key2":"value2", etc} ^ i want the string value "key1" How do I retrieve the string "key1" from data? I know I can set a property dynamically like data[prop]=value but i want to know what prop is from an object passed in. If that doesn't make sense I suppose I could try to explain more. Thanks! I eventually want to do something like: for (var i = 0; i<data.length; i++) { var name = data[i].getPropertyName() <--- not a real function // do stuff }

• Void pointer cast C++ and GTK

  - by Tarantula

  See this GTK callback function: static gboolean callback(GtkWidget *widget, GdkEventButton *event, gpointer *data) { AnyClass *obj = (AnyClass*) data; // using obj works } (please note the gpointer* on the data). And then the signal is connected using: AnyClass *obj2 = new AnyClass(); gtk_signal_connect(/*GTK params (...)*/, callback, obj2); See that the *AnyClass is going to be cast to gpointer* (void**). In fact, this is working now. The callback prototype in GTK documentation is "gpointer data" and not "gpointer *data" as shown in code, what I want to know is: how this can work ? Is this safe ?

• PHP detect if page is reloaded with PHP_SELF

  - by FFish

  I have a form that reloads the page with the updated data: <form name="form" method="post" action="<?php echo $_SERVER['PHP_SELF']; ?>"> ... <input type="submit" name="Submit" value="Update data"> </form> When the page is updated I want to display a message "Data updated". There was something like this with Referer I beleve, but can't remember. btw I am also using: if (isset($_POST['Submit'])) { // prevent resending data header("Location: " . $_SERVER['PHP_SELF']); } to avoid the annoying resending data message when the user clicks the back button. Is this correct?

• Which of these Array Initializations is better in Ruby?

  - by Bragaadeesh

  Hi, Which of these two forms of Array Initialization is better in Ruby? Method 1: DAYS_IN_A_WEEK = (0..6).to_a HOURS_IN_A_DAY = (0..23).to_a @data = Array.new(DAYS_IN_A_WEEK.size).map!{ Array.new(HOURS_IN_A_DAY.size) } DAYS_IN_A_WEEK.each do |day| HOURS_IN_A_DAY.each do |hour| @data[day][hour] = 'something' end end Method 2: DAYS_IN_A_WEEK = (0..6).to_a HOURS_IN_A_DAY = (0..23).to_a @data = {} DAYS_IN_A_WEEK.each do |day| HOURS_IN_A_DAY.each do |hour| @data[day] ||= {} @data[day][hour] = 'something' end end The difference between the first method and the second method is that the second one does not allocate memory initially. I feel the second one is a bit inferior when it comes to performance due to the numerous amount of Array copies that has to happen. However, it is not straight forward in Ruby to find what is happening. So, if someone can explain me which is better, it would be really great! Thanks

• Create a (edit) hyperlink in front of dropdownbox with jQuery

  - by CziX

  I have a table with some data. All data is contained in dropdownboxes and textbox. But it isn't easy to see, what is newly written input and what is data from the database. So I want to create a (edit) after these boxes, and replace the boxes with a literal where the contained value in the dropdownbox stands. When the edit-button is pushed the literal goes away and the dropdownbox appears instead, so it is possible to edit the data. This is all, the jQuery don't have to save the data to database, I have functionality to that in a save-button. I don't want to use any extra plugin to jQuery, because it seems to be a fairly simpel task. Any good ideas?

  Is there is easy command in matlab which prevents program from crashing when it reads characters? I use xlsread to read a (20 400) matrix data , the first row and column get disregarded as they have headers, so that: data = xlsread ( ' C:\file.xls') results in data with a size of (19 399). I have a problem, some cells have missing data and it's written ' missing' and on some data sets i have headers reappear in middle. Is there a way to skip these characters without the program crashing and me having to open the file in excel and deleting those fields? Thanks

  - by user144842

  This line of code is working fine for Firefox $("#<%=txt1.ClientID%>").text() but not for IE8 and IE7.

• SQLite delete the last 25% of records in a database.

  - by Steven smethurst

  I am using a SQLite database to store values from a data logger. The data logger will eventually fills up all the available hard drive space on the computer. I'm looking for a way to remove the last 25% of the logs from the database once it reaches a certain limit. Using the following code: $ret = Query( 'SELECT id as last FROM data ORDER BY id desc LIMIT 1 ;' ); $last_id = $ret[0]['last'] ; $ret = Query( 'SELECT count( * ) as total FROM data' ); $start_id = $last_id - $ret[0]['total'] * 0.75 ; Query( 'DELETE FROM data WHERE id < '. round( $start_id, 0 ) ); A journal file gets created next to the database that fills up the remaining space on the drive until the script fails. How/Can I stop this journal file from being created? Anyway to combined all three SQL queries in to one statement?

• Squid + Dans Guardian (simple configuration)

  - by The Digital Ninja

  I just built a new proxy server and compiled the latest versions of squid and dansguardian. We use basic authentication to select what users are allowed outside of our network. It seems squid is working just fine and accepts my username and password and lets me out. But if i connect to dans guardian, it prompts for username and password and then displays a message saying my username is not allowed to access the internet. Its pulling my username for the error message so i know it knows who i am. The part i get confused on is i thought that part was handled all by squid, and squid is working flawlessly. Can someone please double check my config files and tell me if i'm missing something or there is some new option i must set to get this to work. dansguardian.conf # Web Access Denied Reporting (does not affect logging) # # -1 = log, but do not block - Stealth mode # 0 = just say 'Access Denied' # 1 = report why but not what denied phrase # 2 = report fully # 3 = use HTML template file (accessdeniedaddress ignored) - recommended # reportinglevel = 3 # Language dir where languages are stored for internationalisation. # The HTML template within this dir is only used when reportinglevel # is set to 3.

• ant ftp doesn't download files in subdirectories

  - by Kristof Neirynck

  Hello, I'm trying to download files in subdirectories from an ftp server with ant. The exact set of files is known. Some of them are in subdirectories. Ant only seems to download the ones in the root directory. It does work if I download all files without listing them. The first ftp action should do the exact same thing as the second. Instead it complains about "Hidden files" and seems to prefix the paths with "\\". Does anyone know what's wrong here? Is this a bug in commons-net? build.xml <?xml version="1.0" encoding="utf-8"?> <project name="example" default="example" basedir="."> <taskdef name="ftp" classname="org.apache.tools.ant.taskdefs.optional.net.FTP" /> <target name="example"> <!-- 2 files retrieved --> <ftp action="get" verbose="true" server="localhost" userid="example" password="example"> <fileset dir="downloads" casesensitive="false" includes="root1.txt,root2.txt,a/a.txt,a/b/ab.txt,c/c.txt" /> </ftp> <!-- 5 files retrieved --> <ftp action="get" verbose="true" server="localhost" userid="example" password="example"> <fileset dir="downloads" casesensitive="false" includes="**/*" /> </ftp> </target> </project> run_ant.bat @ECHO OFF PUSHD %~dp0 SET CLASSPATH= SET ANT_HOME=C:\apache-ant-1.8.0 SET ant=%ANT_HOME%\bin\ant.bat SET antoptions=-nouserlib -noclasspath -d SET ftpjars=^ -lib lib\jakarta-oro-2.0.8.jar ^ -lib lib\commons-net-2.0.jar CALL %ant% %antoptions% %ftpjars% > output.txt POPD output.txt Unable to locate tools.jar.

• CreationName for SSIS 2008 and adding components programmatically

  If you are building SSIS 2008 packages programmatically and adding data flow components, you will probably need to know the creation name of the component to add. I can never find a handy reference when I need one, hence this rather mundane post. See also CreationName for SSS 2005. We start with a very simple snippet for adding a component: // Add the Data Flow Task package.Executables.Add("STOCK:PipelineTask"); // Get the task host wrapper, and the Data Flow task TaskHost taskHost = package.Executables[0] as TaskHost; MainPipe dataFlowTask = (MainPipe)taskHost.InnerObject; // Add OLE-DB source component - ** This is where we need the creation name ** IDTSComponentMetaData90 componentSource = dataFlowTask.ComponentMetaDataCollection.New(); componentSource.Name = "OLEDBSource"; componentSource.ComponentClassID = "DTSAdapter.OLEDBSource.2"; So as you can see the creation name for a OLE-DB Source is DTSAdapter.OLEDBSource.2.

• SQL SERVER – History of SQL Server Database Encryption

  - by pinaldave

  I recently met Michael Coles and Rodeney Landrum the author of one of the kind book Expert SQL Server 2008 Encryption at SQLPASS in Seattle. During the conversation we ended up how Microsoft is evolving encryption technology. The same discussion lead to talking about history of encryption tools in SQL Server. Michale pointed me to page 18 of his book of encryption. He explicitly give me permission to re-produce relevant part of history from his book. Encryption in SQL Server 2000 Built-in cryptographic encryption functionality was nonexistent in SQL Server 2000 and prior versions. In order to get server-side encryption in SQL Server you had to resort to purchasing or creating your own SQL Server XPs. Creating your own cryptographic XPs could be a daunting task owing to the fact that XPs had to be compiled as native DLLs (using a language like C or C++) and the XP application programming interface (API) was poorly documented. In addition there were always concerns around creating wellbehaved XPs that “played nicely” with the SQL Server process. Encryption in SQL Server 2005 Prior to the release of SQL Server 2005 there was a flurry of regulatory activity in response to accounting scandals and attacks on repositories of confidential consumer data. Much of this regulation centered onthe need for protecting and controlling access to sensitive financial and consumer information. With the release of SQL Server 2005 Microsoft responded to the increasing demand for built-in encryption byproviding the necessary tools to encrypt data at the column level. This functionality prominently featured the following: Support for column-level encryption of data using symmetric keys or passphrases. Built-in access to a variety of symmetric and asymmetric encryption algorithms, including AES, DES, Triple DES, RC2, RC4, and RSA. Capability to create and manage symmetric keys. Key creation and management. Ability to generate asymmetric keys and self-signed certificates, or to install external asymmetric keys and certificates. Implementation of hierarchical model for encryption key management, similar to the ANSI X9.17 standard model. SQL functions to generate one-way hash codes and digital signatures, including SHA-1 and MD5 hashes. Additional SQL functions to encrypt and decrypt data. Extensions to the SQL language to support creation, use, and administration of encryption keys and certificates. SQL CLR extensions that provide access to .NET-based encryption functionality. Encryption in SQL Server 2008 Encryption demands have increased over the past few years. For instance, there has been a demand for the ability to store encryption keys “off-the-box,” physically separate from the database and the data it contains. Also there is a recognized requirement for legacy databases and applications to take advantage of encryption without changing the existing code base. To address these needs SQL Server 2008 adds the following features to its encryption arsenal: Transparent Data Encryption (TDE): Allows you to encrypt an entire database, including log files and the tempdb database, in such a way that it is transparent to client applications. Extensible Key Management (EKM): Allows you to store and manage your encryption keys on an external device known as a hardware security module (HSM). Cryptographic random number generation functionality. Additional cryptography-related catalog views and dynamic management views. SQL language extensions to support the new encryption functionality. The encryption book covers all the tools in its various chapter in one simple story. If you are interested how encryption evolved and reached to the stage where it is today, this book is must for everyone. You can read my earlier review of the book over here.

• Screen Scraping Twitter

  - by BRADINO

  I got an email today asking for help to scrape Twitter. In particular, to be able to login. So I am going to show everyone, NOT to encourage anyone to violate Twitters terms of use but as an educational blog post about how PHP and cURL can be used to post variables and store cookies. Again, I am using the cScrape class I wrote, which you can download. Step 1 First go to twitter.com and look at the source code of the login to get the form field names and the form post location. You will see that the form posts to https://twitter.com/session and the username and password fields are session[username_or_email] and session[password] respectively. Step 2 Now you are ready to login. So using the fetch function in the Scrape class you create an associative array to contain the form values you want to post. The other thing you will need to do is uncomment the lines for CURLOPT_COOKIEFILE and CURLOPT_COOKIEJAR. Cookies will be required to stay logged in and scrape around. The paths to the cookie files need to be writable by your app. Also you will need to uncomment the line about CURLOPT_FOLLOWLOCATION. $data = array('session[username_or_email]' => "bradino", 'session[password]' => "secret"); $scrape->fetch('https://twitter.com/sessions',$data); Step 1.5 Oops that didn't work. All I got back was 403 Forbidden: The server understood the request, but is refusing to fulfill it. Ahhh I see another variable called authenticity_token I bet Twitter was looking for that. So let's back up and first hit twitter.com to get the authenticity_token variable, and then make the login post request with that variable included in our array of parameters. $scrape->fetch('https://twitter.com'); $data = array('session[username_or_email]' => "bradino", 'session[password]' => "secret"); $data['authenticity_token'] = $scrape->fetchBetween('name="authenticity_token" type="hidden" value="','"',$scrape->result); $scrape->fetch('https://twitter.com/sessions',$data); echo $scrape->result; So that's basically it. Now you are logged in and can scrape around and request other pages as you normally would. Sorry it wasn't a longer post. I really do enjoy this kind of stuff so if anyone has a request, hit me up. Errors? 1) Make sure that you are properly parsing the token variable 2) Make sure that you uncommented the lines about CURLOPT_COOKIEFILE and CURLOPT_COOKIEJAR, those options need to be enabled and be sure the path set is writable by your application 3) Make sure that the path to the cookie file is writable and that it is getting data written to it 4) If you get a message about being redirected you need to uncomment the line about CURLOPT_FOLLOWLOCATION, that option needs to be enabled true

• SQL SERVER – Merge Operations – Insert, Update, Delete in Single Execution

  - by pinaldave

  This blog post is written in response to T-SQL Tuesday hosted by Jorge Segarra (aka SQLChicken). I have been very active using these Merge operations in my development. However, I have found out from my consultancy work and friends that these amazing operations are not utilized by them most of the time. Here is my attempt to bring the necessity of using the Merge Operation to surface one more time. MERGE is a new feature that provides an efficient way to do multiple DML operations. In earlier versions of SQL Server, we had to write separate statements to INSERT, UPDATE, or DELETE data based on certain conditions; however, at present, by using the MERGE statement, we can include the logic of such data changes in one statement that even checks when the data is matched and then just update it, and similarly, when the data is unmatched, it is inserted. One of the most important advantages of MERGE statement is that the entire data are read and processed only once. In earlier versions, three different statements had to be written to process three different activities (INSERT, UPDATE or DELETE); however, by using MERGE statement, all the update activities can be done in one pass of database table. I have written about these Merge Operations earlier in my blog post over here SQL SERVER – 2008 – Introduction to Merge Statement – One Statement for INSERT, UPDATE, DELETE. I was asked by one of the readers that how do we know that this operator was doing everything in single pass and was not calling this Merge Operator multiple times. Let us run the same example which I have used earlier; I am listing the same here again for convenience. --Let’s create Student Details and StudentTotalMarks and inserted some records. USE tempdb GO CREATE TABLE StudentDetails ( StudentID INTEGER PRIMARY KEY, StudentName VARCHAR(15) ) GO INSERT INTO StudentDetails VALUES(1,'SMITH') INSERT INTO StudentDetails VALUES(2,'ALLEN') INSERT INTO StudentDetails VALUES(3,'JONES') INSERT INTO StudentDetails VALUES(4,'MARTIN') INSERT INTO StudentDetails VALUES(5,'JAMES') GO CREATE TABLE StudentTotalMarks ( StudentID INTEGER REFERENCES StudentDetails, StudentMarks INTEGER ) GO INSERT INTO StudentTotalMarks VALUES(1,230) INSERT INTO StudentTotalMarks VALUES(2,255) INSERT INTO StudentTotalMarks VALUES(3,200) GO -- Select from Table SELECT * FROM StudentDetails GO SELECT * FROM StudentTotalMarks GO -- Merge Statement MERGE StudentTotalMarks AS stm USING (SELECT StudentID,StudentName FROM StudentDetails) AS sd ON stm.StudentID = sd.StudentID WHEN MATCHED AND stm.StudentMarks > 250 THEN DELETE WHEN MATCHED THEN UPDATE SET stm.StudentMarks = stm.StudentMarks + 25 WHEN NOT MATCHED THEN INSERT(StudentID,StudentMarks) VALUES(sd.StudentID,25); GO -- Select from Table SELECT * FROM StudentDetails GO SELECT * FROM StudentTotalMarks GO -- Clean up DROP TABLE StudentDetails GO DROP TABLE StudentTotalMarks GO The Merge Join performs very well and the following result is obtained. Let us check the execution plan for the merge operator. You can click on following image to enlarge it. Let us evaluate the execution plan for the Table Merge Operator only. We can clearly see that the Number of Executions property suggests value 1. Which is quite clear that in a single PASS, the Merge Operation completes the operations of Insert, Update and Delete. I strongly suggest you all to use this operation, if possible, in your development. I have seen this operation implemented in many data warehousing applications.

• jQuery Templates on Microsoft Ajax CDN

  - by Stephen Walther

  The beta version of the jQuery Templates plugin is now hosted on the Microsoft Ajax CDN. You can start using the jQuery Templates plugin in your application by referencing both jQuery 1.4.2 and jQuery Templates from the CDN. Here are the two script tags that you will want to use when developing an application: <script type="text/javascript" src=”http://ajax.microsoft.com/ajax/jquery/jquery-1.4.2.js”></script> <script type="text/javascript" src=”http://ajax.microsoft.com/ajax/jquery.templates/beta1/jquery.tmpl.js”></script> In addition, minified versions of both files are available from the CDN: <script type="text/javascript" src="http://ajax.microsoft.com/ajax/jquery/jquery-1.4.2.min.js"></script> <script type="text/javascript" src="http://ajax.microsoft.com/ajax/jquery.templates/beta1/jquery.tmpl.min.js"></script> Here’s a full code sample of using jQuery Templates from the CDN to display pictures of cats from Flickr: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <title>Cats</title> <style type="text/css"> html { background-color:Orange; } #catBox div { width:250px; height:250px; border:solid 1px black; background-color:White; margin:5px; padding:5px; float:left; } #catBox img { width:200px; height: 200px; } </style> </head> <body> <h1>Cat Photos!</h1> <div id="catBox"></div> <script type="text/javascript" src="http://ajax.microsoft.com/ajax/jquery/jquery-1.4.2.min.js"></script> <script type="text/javascript" src="http://ajax.microsoft.com/ajax/jquery.templates/beta1/jquery.tmpl.min.js"></script> <script id="catTemplate" type="text/x-jquery-tmpl"> <div> <b>${title}</b> <br /> <img src="${media.m}" /> </div> </script> <script type="text/javascript"> var url = "http://api.flickr.com/services/feeds/groups_pool.gne?id=44124373027@N01&lang=en-us&format=json&jsoncallback=?"; // Grab some flickr images of cats $.getJSON(url, function (data) { // Format the data using the catTemplate template $("#catTemplate").tmpl(data.items).appendTo("#catBox"); }); </script> </body> </html> This page displays a list of cats retrieved from Flickr: Notice that the cat pictures are retrieved and rendered with just a few lines of code: var url = "http://api.flickr.com/services/feeds/groups_pool.gne?id=44124373027@N01&lang=en-us&format=json&jsoncallback=?"; // Grab some flickr images of cats $.getJSON(url, function (data) { // Format the data using the catTemplate template $("#catTemplate").tmpl(data.items).appendTo("#catBox"); }); The final line of code, the one that calls the tmpl() method, uses the Templates plugin to render the cat photos in a template named catTemplate. The catTemplate template is contained within a SCRIPT element with type="text/x-jquery-tmpl". The jQuery Templates plugin is an “official” jQuery plugin which will be included in jQuery 1.5 (the next major release of jQuery). You can read the full documentation for the plugin at the jQuery website: http://api.jquery.com/category/plugins/templates/ The jQuery Templates plugin is still beta so we would really appreciate your feedback on the plugin. Let us know if you use the Templates plugin in your website.
