• Python character count

  - by user74283

  I have been going over python tutorials in this resource. Everything is pretty clear in the below code which counts number of characters. Only section that i dont understand is the section where count assigned to a list and multiplied by 120. Can anyone explain what is the purpose of this in plain english please. def display(i): if i == 10: return 'LF' if i == 13: return 'CR' if i == 32: return 'SPACE' return chr(i) infile = open('alice_in_wonderland.txt', 'r') text = infile.read() infile.close() counts = 128 * [0] for letter in text: counts[ord(letter)] += 1 outfile = open('alice_counts.dat', 'w') outfile.write("%-12s%s\n" % ("Character", "Count")) outfile.write("=================\n") for i in range(len(counts)): if counts[i]: outfile.write("%-12s%d\n" % (display(i), counts[i])) outfile.close()

• Bouncy Castle, RSA : transforming keys into a String format

  - by Rami W.

  Hi, iam using RSA(Bouncy Castle API) in my c# porject. Igenerated the keypair with this method RsaKeyPairGenerator r = new RsaKeyPairGenerator(); r.Init(new KeyGenerationParameters(new SecureRandom(), 1024)); AsymmetricCipherKeyPair keys = r.GenerateKeyPair(); AsymmetricKeyParameter private_key = keys.Private; AsymmetricKeyParameter public_key = keys.Public; now i want to save them in txt file but the problem is that i can't convert them to a string format. i read in another post that keys must be serialized using PrivateKeyInfo k = PrivateKeyInfoFactory.CreatePrivateKeyInfo(private_key); byte[] serializedKey = k.ToAsn1Object().GetDerEncoded(); Is it the right way ? if yes, what should i do after this ? just convert them from byte[] to String ? thx for any help.

• Codeigniter redirect repeats controller name in URL

  - by Obay

  This is my controller: class Timesheet extends Controller { ... function index() { //loads view with a form that submits to "timesheet/change_date" } function summary() { //loads view with a form that submits to "timesheet/change_week" } function change_date() { ... redirect('timesheet'); } function change_week() { ... redirect('timesheet/summary'); } ... } The first form is located at http://localhost/dts/index.php/timesheet and when I submit the change_date form, it correctly goes thru the change_date() function and re-loads http://localhost/dts/index.php/timesheet correctly. However, the second form is located at http://localhost/dts/index.php/timesheet/summary, and when I submit the change-week form, it goes thru the change_week() function but goes to http://localhost/dts/index.php/timesheet/timesheet/change_week. Notice the word timesheet is repeated. When I submit the form again, another timesheet is added. What's wrong and how do I improve my code? My .htaccess is below: RewriteEngine on RewriteCond $1 !^(index\.php|webroot|robots\.txt) RewriteRule ^(.*)$ index.php/$1 [L]

• Google Local Search API

  - by Gublooo

  hey guys couple of quick questions 1) In the local search results - we can get a lot of parameters like street title, address, city, state, lat, long , url etc - In order for me to uniquely identify this record - can I consider URL to be unique to this address or concatenation of latitude and longitude Ref: http://code.google.com/apis/ajaxsearch/documentation/reference.html#_class_GlocalResult 2) In terms of usage, depending upon what user enters, I'm displaying a list of local business for the user to choose. Now when a user selects a particular business address - is it legal for me to store that business address along with lat and longitude information in my database for future look ups. I've seen a lot of blogs talking about storing the lat/long info but just want to be sure that i'm not violating and google rules. Thanks

• Remove index.php in CodeIgniter

  - by Gabriel Bianconi

  Hello. I'm trying to remove the 'index.php' from CI Urls. I've tried many solutions, none of them worked. I've already set these variables in 'config.php': $config['index_page'] = ""; $config['uri_protocol'] = "REQUEST_URI"; And my current .htaccess is: Options +FollowSymLinks RewriteEngine On RewriteBase / RewriteCond %{HTTP_HOST} ^plugb.com$ [NC] RewriteRule ^(.*)$ http://www.plugb.com/$1 [R=301,L] RewriteCond $1 !^(index\.php|files|robots\.txt) RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule ^(.*)$ index.php/$1 [L,QSA] The www prefix part works fine.

• Insert multiple values using INSERT INTO

  - by Ben McCormack

  In SQL Server 2005, I'm trying to figure out why I'm not able to insert multiple fields into a table. The following query, which inserts one record, works fine: INSERT INTO [MyDB].[dbo].[MyTable] ([FieldID] ,[Description]) VALUES (1000,N'test') However, the following query, which specifies more than one value, fails: INSERT INTO [MyDB].[dbo].[MyTable] ([FieldID] ,[Description]) VALUES (1000,N'test'),(1001,N'test2') I get this message: Msg 102, Level 15, State 1, Line 5 Incorrect syntax near ','. When I looked up the help for INSERT in SQL Sever Management Studio, one of their examples showed using the "Values" syntax that I used (with groups of values in parentheses and separated by commas). The help documentation I found in SQL Server Management Studio looks like it's for SQL Server 2008, so perhaps that's the reason that the insert doesn't work. Either way, I can't figure out why it won't work.

• Zend + Pop Up's balloons on Server Problem

  - by LookUp Webmaster

  Dear Friends from Stackoverflow, Please help me with a problem that i'm having when uploading my project to the server. I'm using pop up's balloons (http://mckay.cshl.edu/balloons.html) for a project using Zend FW and it works fine on my localhost. (I'm using MAMP on MacOSX) but when I upload the webpage to the server, the text inside the balloons is displayed but the images that form the balloon are not, so somehow the js does not recognize the url to the images (the path it's correct, i've checked several times). The server is an Ubuntu 9.04 virtual machine from rackspace.com, running a LAMP server. I'm using the REWRITE function in Apache, so i guess maybe that's the problem. The rewrite configuration is set up using a .htaccess file with the following content: SetEnv APPLICATION_ENV development Options +FollowSymlinks RewriteEngine ON RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule !.(js|ico|txt|gif|jpg|png|css|html)$ index.php Does anyone knows what the problem might be? Best Regards,

• Why does ASP.NET web site reference assembly from GAC, when adding local reference?

  - by Konstantin

  When you use ASP.NET web site (instead of web application model) and add reference to an assembly from local folder, Visual Studio, it seems, understands that this local assembly is also in GAC and so does NOT copy this assembly to bin folder (as it does with non-GAC assemblies), but simply adds new record in web.config file. Why such a behaviour? Is it possible to force copy to bin folder (I need this since .dll is not on target environment)? I can add assembly to bin folder as file and it will work, but in this case bin folder contents will be in source control, which is not good.

• MySqlDataAdapter or MySqlDataReader for bulk transfer?

  - by Jeff Meatball Yang

  I'm using the MySql connector for .NET to copy data from MySql servers to SQL Server 2008. Has anyone experienced better performance using one of the following, versus the other? DataAdapter and calling Fill to a DataTable in chunks of 500 DataReader.Read to a DataTable in a loop of 500 I am then using SqlBulkCopy to load the 500 DataTable rows, then continue looping until the MySql record set is completely transferred. I am primarily concerned with using a reasonable amount of memory and completing in a short amount of time. Any help would be appreciated!

• getjson and servers

  - by gheil.apl

  Is getJSON only useful for those who control a server? Is there any other alternative for getting data from a file? i tried $.getJSON("good.json", function(data){ out=out+"good.json: "+data + ","; }); where good.json = {"a":"1","b":"2"} and got a result of 'null' for data. These all are valid JSON files, and all give null when used in the above: good.htm assoc.json assoc.js stub.json stub.js test.js test.txt and all get a null result... The above is in an interactive setting at http://jsbin.com/dbJSON/8/edit the output (of null) is to be had by clicking 'output'.

• Ajax based progress bar

  - by Punit

  I am developing a progress bar using Ajax. My client side code is working fine, but I have issue at server side. I am using C based CGI. if(i == inc && pb_inc<=100) { fptr = fopen("progress_bar.txt", "w"); fprintf(fptr,"%d", j); fclose(fptr); pb_inc++; } basically I am increasing progress bar after certain number of bytes. What I see here is that the CGI doesn't let display any data to text file until it has sent all the data to file one by one. i have referred to http://www.redips.net/javascript/ajax-progress-bar/ Any idea whats happening here?

• C++: ifstream::getline problem

  - by Jay

  I am reading a file like this: char string[256]; std::ifstream file( "file.txt" ); // open the level file. if ( ! file ) // check if the file loaded fine. { // error } while ( file.getline( string, 256, ' ' ) ) { // handle input } Just for testing purposes, my file is just one line, with a space at the end: 12345 My code first reads the 12345 successfully. But then instead of the loop ending, it reads another string, which seems to be a return/newline. I have saved my file both in gedit and in nano. And I have also outputted it with the Linux cat command, and there is no return on the end. So the file should be fine. Why is my code reading a return/newline? Thanks.

• Change write-host output color based on foreach if elseif outcome in Powershell

  - by Emo

  I'm trying to change the color of write-host output based on the lastrunoutcome property of SQL Server jobs in Powershell....as in...if a job was successfull, the output of lastrunoutcome is "Success" in green....if failed, then "Failed" in red. I have the script working to get the desired job status...I just don't know how to change the colors. Here's what I have so far: # Check for failed SQL jobs on multiple servers [reflection.assembly]::LoadWithPartialName("Microsoft.SqlServer.Smo") | out-null foreach ($svr in get-content "C:\serverlist2.txt") { $a = get-date $BegDate = (Get-Date $a.AddDays(-1) -f d) + " 12:00:00 AM" $BegDateTrans = [system.datetime]$BegDate write-host $svr $srv=New-Object "Microsoft.SqlServer.Management.Smo.Server" "$svr" $srv.jobserver.jobs | where-object {$_.lastrundate -ge $BegDateTrans -and $_.Name -notlike "????????-????-????-????-????????????"} | format-table name,lastrunoutcome,lastrundate -autosize foreach ($_.lastrunoutcome in $srv.jobserver.jobs) { if ($_.lastrunoutcome = 0) { -forgroundcolor red } else {} } } This seems to be the closest I've gotten...but it's giving me an error of ""LastRunOutcome" is a ReadOnly property." Any help would be greatly appreciated! Thanks! Emo

• MySQL Export with Column Heading

  - by st4nt0n

  Hello - I am very, very, new to mySQL. I've got experience in general technical terms, but not with the syntax or concepts of mySQL. I have been tasked with exporting a table from MySQL into a pipe delimited .txt or .xls that I can use to add 7500 more records to manually, then import back into the table. I tried to use INTO OUTFILE, but I don't get column headings, which I need for reference to merge the new records. Is there a good resource that can explain this to a complete novice? I would usually go down to my bookstore and start learning, but I'm on a bit of a time crunch. Thanks all!

• Best way to implement keywords for image upload gallery

  - by Dan Berlyoung

  I'm starting to spec out an image gallery type system similar to Facebook's. Members of the site will be able to create image galleries and upload images for others to view. Images will have keywords the the uploader can specify. Here's the question, what's the best way to model this? With image and keyword tables linked vi a HABTM relation? Or a single image table with the keywords saved as comma delimited values in a text field in the image record? Then search them using a LIKE or FULL TEXT index function? I want to be able to pull up all images containing a given keyword as well as generate a keyword cloud. I'm leaning toward the HABTM setup but I wanted to see what everyone else though. Thanks!!
