• Which would be better? Storing/access data in a local text file, or in a database?

  - by TerranRich

  Basically, I'm still working on a puzzle-related website (micro-site really), and I'm making a tool that lets you input a word pattern (e.g. "r??n") and get all the matching words (in this case: rain, rein, ruin, etc.). Should I store the words in local text files (such as words5.txt, which would have a return-delimited list of 5-letter words), or in a database (such as the table Words5, which would again store 5-letter words)? I'm looking at the problem in terms of data retrieval speeds and CPU server load. I could definitely try it both ways and record the times taken for several runs with both methods, but I'd rather hear it from people who might have had experience with this. Which method is generally better overall?

• Can I use notepad++ exe in my application ?

  - by Harikrishna

  I am parsing html file with the help of the html agility pack to extract the table data from the html file. But there is some html files where there is no ending tags which is optional or there is no starting tag which is also optional.So html agility pack does not parse that html page properly.If I open the content of that html file in the notepad++ then with the option TestFX-->TestFX HTML Tidy-->TiDy clean document and make the content tidy like this. And now this file If I parse with the html agility pack then it parse it properly. Making html page tidy with notepad++ is best option. So I don't know but user can not do this like first he/she makes the page tidy with notepad++ and then go ahead.Then what should I do ?

• AppEngine and Django: including a template file

  - by PythonPower

  As the title suggests, I'm using Google App Engine and Django. I have quite a bit of identical code across my templates and would like to reduce this by including template files. So, in my main application directory I have the python handler file, the main template, and the template I want to include in my main template. I would have thought that including {% include "fileToInclude.html" %} would work on its own but that simply doesn't include anything. I assume I have to set something up, maybe using TEMPLATE_DIRS, but can't figure it out on my own. EDIT: I've tried: TEMPLATE_DIRS = (os.path.join(os.path.dirname(__file__), 'templates'), ) But to no avail. I'll try some other possibilities too.

• What are the advantages and disadvantages of plug-in based architecture?

  - by RP

  I want to do the architectural design for a software that can be used integrate various third party software’s (executable) under one platform. Standard project types will be added to the platform by default. The project type defines the way in which the different software will be executed and their input and output files. The user can customize the available standard project type and that will be added to the platform as new project type which defines new custom execution flow. Also it should support easy extension and customization of the features. I read that plug-in based architecture supports both. What are the advantages and disadvantages of plug-in based architecture? Do we have any better architecture which can be used for this kind of scenario? Thanks in advance:)

• copying the contents of an image file

  - by Ganesh

  I am designing an image decoder and as a first step I tried to just copy the using c. i.e open the file, and write its contents to a new file. Below is the code that I used. while((c=getc(fp))!=EOF) fprintf(fp1,"%c",c); where fp is the source file and fp1 is the destination file. The program executes without any error, but the image file(".bmp") is not properly copied. I have observed that the size of the copied file is less and only 20% of the image is visible, all else is black. When I tried with simple text files, the copy was complete. Do you know what the problem is?

• frequently merge changes between branch and trunk?

  - by John

  My team and I are using svn branches for the first time. Before, we use to work only from the trunk. Over the past 2 weeks, we've been refactoring and developing new code against our branch. But during that time, another developer has been making bug fixes to code in the trunk and deploying it to the production server. We would like to frequently "update" our branch with changes from the trunk to make sure we get the latest fixes. But the problem is that we're making drastic changes to our branch, and many files have been renamed. I have a feeling every "update" we do on our branch that takes changes from trunk will cause a conflict, unless we some how get subversion to recognise that fileA.html in trunk is really fileB.html in branch. Am I using subversion branches correctly? Am I using the word "update" correctly? Are frequent "updates" in branch advisable?

• When does an ASP.NET Website project recompile?

  - by jdk

  Where's the info that tells the kinds of changes and files which cause a website project (not web application project) to recompile itself? The reason I'm asking is because we don't want users to lose their sessions. So we want to update the live website with recompile changes in the very wee hours of the morning, but would prefer to make changes during the day to expedite them. We promote to a staging server first and could watch it there but a definitive list would be nice in advance. If there's not a definitive list, a list can be started here:

• Fully automated MS SQL Restore

  - by hasen j

  I'm not very fluent with MS-SQL commands. I need a script to restore a database from a .bak file and move the logical_data and logical_log files to a specific path. I can do: restore filelistonly from disk='D:\backups\my_backup.bak' This will give me a result set with a column LogicalName, next I need to use the logical names from the result set in the restore command: restore database my_db_name from disk='d:\backups\my_backups.bak' with file=1, move 'logical_data_file' to 'd:\data\mydb.mdf', move 'logical_log_file' to 'd:\data\mylog.ldf' How do I capture the logical names from the first result set into variables that can be supplied to the "move" command? I think the solution might be trivial, but I'm pretty new to mssql.

• Is there any way to store full size image returned from camera activity in internal memory ?

  - by SimpleGuy

  I am using Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE); intent.putExtra(MediaStore.EXTRA_OUTPUT,Uri.fromFile(externalFileObj)); intent to call default camera activity. To get full image you need to specify intent.putExtra(). But this always requires URI that works only for external storage files. I tried to create a temp.jpg image in internal memory and pass its URI Uri.fromFile(new File(getFilesDir() + "/temp.jpg")); but the camera activity won't return back after the image is captured. So there is no way to get Full size image from default camera application in our activity without using any external storage ? Assuming that the device do not have SD card or currently in use is there no way I can avoid using it ? Yes I know we can create our own camerapreview surface but I want to use the default camera application as it is natural with many more options. Thanks.

• Correct folder structure for sites

  - by Francesca

  I've just started tidying up the server for a particular site and am running into some trouble when moving files. I originally had style.css in my main folder, and another folder called images, so paths in the .css went images/myimage.png Now I have moved style.css into another folder called css. So the image links in the CSS no longer work, as it's looking for the folder images from it's own CSS folder. I changed the file path to /images/myimage.png as I thought this would make it climb up a level and then look for the images folder, but this doesn't seem to work. I'm interested to see what solutions people have and also any suggestions on how people organise their folders for a particular site. Thanks!

• Eclipse javascript character encoding

  - by Bardock

  Hi, I'd like to display some language specific characters from javascript but I can't. My app is a Java webapp and the front end is jQuery. All the characters that are sended from the server - in a JSP or with AJAX - are displayed properly. When I want to display some text hardcoded in to the javascript file it's broken. I'm using Eclipse. In the JSP's header I use: <%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%> I've tried this (charset in the script element) too: <script type="text/javascript" charset="utf-8"><c:import url="/JS/mainJS.js" /></script> In my Eclipse I've set the project properties / text file encoding to UTF-8 AND I've checked the JS files' resource properties / text file encoding that is UTF-8 too. But when I try this: $.test = function(){ var s = "éééáááuuuu"; alert(s); } I get: éééáááűűűű The strange thing is that: When I try in a separate html file (in the same project), It's working: <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> <head> <title>Test</title> <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script> <style type="text/css"> body {background: #c0c0c0;} </style> <script type="text/javascript"> $(document).ready(function(){ var s = "éááuuúúú"; $("#console").text(s); alert(s); }) </script> </head> <body> <div id="console"></div> </body> </html> Even if I DO NOT use any content type and page encoding settings. What is the problem? What shall I do? (I'm using Apache Tomcat integrated in Eclipse) Thanks in advance!

• Asp.net MVC database connection setting in Visual studio 2008

  - by AK47

  I am trying to learn Asp.net MVC framework. I was looking at the video tutorial at the link below http://www.asp.net/learn/mvc-videos/video-395.aspx In this video the very first step is to add a new database to the example application. I have visual studio installed on my development machine but the SqlServer Express is running on a different machine, so when I try and add a new database following the same steps as the video I get the following error "Connections to SQL Server files(*.mdf) require SQL express 2005 to funciton properly. Please verify the installation of the component or download from the url" I am assuming this is because Visual studio is looking for an instance of SQL express on my local machine and since it doesnt exist on the local machine,it errors out. So how do i tell visual studio, to connect to a different machine and create the database there? I am using Visual studio 2008 with .net 3.5 Sp1

• .htaccess stupid issue

  - by justnoone

  I have a server where I can only configure httpd using .htaccess, a cannot access global configuration. I want to rewrite almost every non-existing path to index.php, so I did something like: RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule ^(.*)$ index.php?path=$1 [L,QSA] And that is ok. But another thing I want to do is to prevent access to path where I keep PHP files (I cannot store them somewhere else) which is for example /php. I would like that anything starting with /php rewrites to index.php?path=php... so I did something like: RewriteCond %{REQUEST_URI} ^/php.* RewriteRule ^(.*)$ /index.php?path=$1 [L,QSA] And that also would work ok if I had access to global configuration. In case of per-directory configuration, when I access /php it rewrites it to index.php?path=php and than puts directory name before that: /php/index.php?path=php. I read documentation and I realize that it uses internal redirects when per-directory confoguration is used. How can I avoid this behavior?

• does a git repository have its own local value for core.autocrlf that overrides the global one?

  - by Warren P

  As per this question, I understand that core.autocrlf=true in git will cause CRLF to LF translations. However when I type : git config core.autocrlf I see: false However, when I stage modified files that are already in the repo, I still get these warnings: Warning: CRLF will be replaced by LF in File1.X. The file will have its original line endings in your working directory. My guess is that the repo copy of the file is already set to "autocrlf=true". Questions: A. How do I query whether a file or git repo is already forcing AutoCrlf? B. How do I turn it autocrlf off?

• server reboot has caused django project to lose directories

  - by wmfox3

  A fully functional Django project as well as a couple in development have all broken following the rebooting of the server. In addition to some pieces of the Django admin returning errors as well as missing .js and .css files, I'm getting errors like this when viewing pages that include images uploaded through the admin. Exception Type: TemplateSyntaxError Exception Value: Caught an exception while rendering: (2, 'No such file or directory') Exception Location: /usr/lib/pymodules/python2.6/django/template/debug.py in render_node, line 81 Python Executable: /usr/bin/python Python Version: 2.6.4 So did the reboot stomp on some part of my configuration/setup or did it fail to restart a critical piece?

• Code to generate random numbers in C++

  - by user1678927

  Basically I have to write a program to generate random numbers to simulate the rolling of a pair of dice. This program should be constructed in multiple files. The main function should be in one file, the other functions should be in a second source file, and their prototypes should be in a header file. First I write a short function that returns a random value between 1 and 6 to simulate the rolling of a single 6-sided die.Second, i write a function that pretends to roll a pair of dice by calling this function twice. My program starts by asking the user how many rolls should be made. Then I write a function to simulate rolling the dice this many times, keeping a count of exactly how many times the values 2,3,4,5,6,7,8,9,10,11,12(each number is the sum of a pair of dice) occur in an array. Later I write a function to display a small bar chart using these counts that ideally would look something like below for a sample of 144 rolls, where the number of asterisks printed corresponds to the count: 2 3 4 5 6 7 8 9 10 11 12 * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * Next, to see how well the random number generator is doing, I write a function to compute the average value rolled. Compare this to the ideal average of 7. Also, print out a small table showing the counts of each roll made by the program, the ideal count based on the frequencies above given the total number of rolls, and the difference between these values in separate columns. This is my incomplete code so far: "Compiler visual studio 2010" int rolling(){ //Function that returns a random value between 1 and 6 rand(unsigned(time(NULL))); int dice = 1 + (rand() %6); return dice; } int roll_dice(int num1,int num2){ //it calls 'rolling function' twice int result1,result2; num1 = rolling(); num2 = rolling(); result1 = num1; result2 = num2; return result1,result2; } int main(void){ int times,i,sum,n1,n2; int c1,c2,c3,c4,c5,c6,c7,c8,c9,c10,c11;//counters for each sum printf("Please enter how many times you want to roll the dice.\n") scanf_s("%i",&times); I pretend to use counters to count each sum and store the number(the count) in an array. I know i need a loop (for) and some conditional statements (if) but m main problem is to get the values from roll_dice and store them in n1 and n2 so then i can sum them up and store the sum in 'sum'.

• Dynamic Custom Fields for Data Model

  - by Jerry Deng

  I am in the process of creating a dynamic database where user will be able to create resource type where he/she can add custom fields (multiple texts, strings, and files) Each resource type will have the ability to display, import, export its data; I've been thinking about it and here are my approaches. I would love to hear what do you guys think. Ideas: just hashing all the custom data in a data field (pro: writing is easier, con: reading back out may be harder); children fields (the model will have multiple fields of strings, fields of text, and fields for file path); fixed number of custom fields in the same table with a key mapping data hash stored in the same row; Non-SQL approach, but then the problem would be generating/changing models on the fly to work with different custom fields;

• How to use ccache selectively?

  - by Anonymous

  I have to compile multiple versions of an app written in C++ and I think to use ccache for speeding up the process. ccache howtos have examples which suggest to create symlinks named gcc, g++ etc and make sure they appear in PATH before the original gcc binaries, so ccache is used instead. So far so good, but I'd like to use ccache only when compiling this particular app, not always. Of course, I can write a shell script that will try to create these symlinks every time I want to compile the app and will delete them when the app is compiled. But this looks like filesystem abuse to me. Are there better ways to use ccache selectively, not always? For compilation of a single source code file, I could just manually call ccache instead of gcc and be done, but I have to deal with a complex app that uses an automated build system for multiple source code files.

• Is there an alternative to FTP?

  - by Danny

  I am trying to find an alternative to FTP? It's a single file transfer up to 4gb. Any suggestions? maybe HTTP? Or should I stick it out with FTP? More info - We have an app that we distribute to tens of thousands of clients that upload single large files. FTP has proven to be error prone with a single file of that size. Speed is always a consideration. 'Resume' is a must. Cost shouldn't be an issue - I guess it depends.

• XMLHttpRequest progressive download?

  - by StackedCrooked

  Just for fun I was creating a JavaScript console for controlling my PC. It involves a small webserver that takes command strings and forwards those to the system using popen calls (to be more specific popen4 on a Ruby mongrel server). The stdout channels are redirected to the http response. The problem is that the response only arrives once the entire contents of stdout has been sent. This is ok for small commands, but not for a command like find / which lists all the files in the system. In such situations it would be nice to have the results shown progressively in the webview (just like in the regular terminal). I thought that using XMLHttpRequest synchronously might result in progressive downloading, but it doesn't seem so. Is there any way to make it work?
