  - by Larry Battle

  Hello, I'm trying to make a script that will download search results from a HTTPS website using POST.

Website appears- input form data - click submit - progressing icon appears - returns new web page with search results( new data but the url doesn't change ) My code: curl -d "postData" -k url

• How to get N random string from a {a1|a2|a3} format string?

  - by Pentium10

  Take this string as input: string s="planets {Sun|Mercury|Venus|Earth|Mars|Jupiter|Saturn|Uranus|Neptune}" How would I choose randomly N from the set, then join them with comma. The set is defined between {} and options are separated with | pipe. The order is maintained. Some output could be: string output1="planets Sun, Venus"; string output2="planets Neptune"; string output3="planets Earth, Saturn, Uranus, Neptune"; string output4="planets Uranus, Saturn";// bad example, order is not correct Java 1.5

• Dreamweaver CS5 - Have Design Window as a Panel?

  - by Oliver Jones

  I've been looking around on the dreamweaver interface, and I'm trying to get my design window as an external panel. Reason is, I have a dual monitor system, and I would like to have the main window (where you can have both code/split/design) on my main screen, but with the code selected, and a design view on my secondary monitor. I'm assuming this can't be done, although I have noticed you can have your code as an external panel (Code Inspector). Would like to hear your input. Thanks

• Is it good practice to name variables differently when defining more than one function?

  - by John

  For example, in this simple function where fun1 takes as input two numbers, adds them together and passes them to function 2 for printing the output. var1_in is local to each function, so is it OK to use the name var1_in in both functions, or is it better practice to call them different things? fun1 <- function (var1_in, var2_in) { var3 = var1_in + var2_in fun2(var3) } fun2 <- function (var1_in) { var4 = var1_in print(var4) }

• Can MySQL reasonably perform queries on billions of rows?

  - by haxney

  I am planning on storing scans from a mass spectrometer in a MySQL database and would like to know whether storing and analyzing this amount of data is remotely feasible. I know performance varies wildly depending on the environment, but I'm looking for the rough order of magnitude: will queries take 5 days or 5 milliseconds? Input format Each input file contains a single run of the spectrometer; each run is comprised of a set of scans, and each scan has an ordered array of datapoints. There is a bit of metadata, but the majority of the file is comprised of arrays 32- or 64-bit ints or floats. Host system |----------------+-------------------------------| | OS | Windows 2008 64-bit | | MySQL version | 5.5.24 (x86_64) | | CPU | 2x Xeon E5420 (8 cores total) | | RAM | 8GB | | SSD filesystem | 500 GiB | | HDD RAID | 12 TiB | |----------------+-------------------------------| There are some other services running on the server using negligible processor time. File statistics |------------------+--------------| | number of files | ~16,000 | | total size | 1.3 TiB | | min size | 0 bytes | | max size | 12 GiB | | mean | 800 MiB | | median | 500 MiB | | total datapoints | ~200 billion | |------------------+--------------| The total number of datapoints is a very rough estimate. Proposed schema I'm planning on doing things "right" (i.e. normalizing the data like crazy) and so would have a runs table, a spectra table with a foreign key to runs, and a datapoints table with a foreign key to spectra. The 200 Billion datapoint question I am going to be analyzing across multiple spectra and possibly even multiple runs, resulting in queries which could touch millions of rows. Assuming I index everything properly (which is a topic for another question) and am not trying to shuffle hundreds of MiB across the network, is it remotely plausible for MySQL to handle this? UPDATE: additional info The scan data will be coming from files in the XML-based mzML format. The meat of this format is in the <binaryDataArrayList> elements where the data is stored. Each scan produces = 2 <binaryDataArray> elements which, taken together, form a 2-dimensional (or more) array of the form [[123.456, 234.567, ...], ...]. These data are write-once, so update performance and transaction safety are not concerns. My naïve plan for a database schema is: runs table | column name | type | |-------------+-------------| | id | PRIMARY KEY | | start_time | TIMESTAMP | | name | VARCHAR | |-------------+-------------| spectra table | column name | type | |----------------+-------------| | id | PRIMARY KEY | | name | VARCHAR | | index | INT | | spectrum_type | INT | | representation | INT | | run_id | FOREIGN KEY | |----------------+-------------| datapoints table | column name | type | |-------------+-------------| | id | PRIMARY KEY | | spectrum_id | FOREIGN KEY | | mz | DOUBLE | | num_counts | DOUBLE | | index | INT | |-------------+-------------| Is this reasonable?

• SQL Invalid Object Name 'AddressType'

  - by salvationishere

  I am getting the above error in my VS 2008 C# method when I try to invoke the SQL getColumnNames stored procedure from VS. This SP accepts one input parameter, the table name, and works successfully from SSMS. Currently I am selecting the AdventureWorks AddressType table for it to pull the column names from this table. I can see teh AdventureWorks table available in VS from my Server Explorer / Data Connection. And I see both the AddressType table and getColumnNames SP showing in Server Explorer. But I am still getting this error listed above. Here is the C# code snippet I use to execute this: public static DataTable DisplayTableColumns(string tt) { SqlDataReader dr = null; string TableName = tt; string connString = "Data Source=.;AttachDbFilename=\"C:\Program Files\Microsoft SQL Server\MSSQL10.MSSQLSERVER\MSSQL\DATA\AdventureWorks_Data.mdf\";Initial Catalog=AdventureWorks;Integrated Security=True;Connect Timeout=30;User Instance=False"; string errorMsg; SqlConnection conn2 = new SqlConnection(connString); SqlCommand cmd = conn2.CreateCommand(); try { cmd.CommandText = "dbo.getColumnNames"; cmd.CommandType = CommandType.StoredProcedure; cmd.Connection = conn2; SqlParameter parm = new SqlParameter("@TableName", SqlDbType.VarChar); parm.Value = TableName; parm.Direction = ParameterDirection.Input; cmd.Parameters.Add(parm); conn2.Open(); dr = cmd.ExecuteReader(); } catch (Exception ex) { errorMsg = ex.Message; } And when I examine the errorMsg it says the following: " at System.Data.SqlClient.SqlConnection.OnError(SqlException exception, Boolean breakConnection)\r\n at System.Data.SqlClient.SqlInternalConnection.OnError(SqlException exception, Boolean breakConnection)\r\n at System.Data.SqlClient.TdsParser.ThrowExceptionAndWarning(TdsParserStateObject stateObj)\r\n at System.Data.SqlClient.TdsParser.Run(RunBehavior runBehavior, SqlCommand cmdHandler, SqlDataReader dataStream, BulkCopySimpleResultSet bulkCopyHandler, TdsParserStateObject stateObj)\r\n at System.Data.SqlClient.SqlDataReader.ConsumeMetaData()\r\n at System.Data.SqlClient.SqlDataReader.get_MetaData()\r\n at System.Data.SqlClient.SqlCommand.FinishExecuteReader(SqlDataReader ds, RunBehavior runBehavior, String resetOptionsString)\r\n at System.Data.SqlClient.SqlCommand.RunExecuteReaderTds(CommandBehavior cmdBehavior, RunBehavior runBehavior, Boolean returnStream, Boolean async)\r\n at System.Data.SqlClient.SqlCommand.RunExecuteReader(CommandBehavior cmdBehavior, RunBehavior runBehavior, Boolean returnStream, String method, DbAsyncResult result)\r\n at System.Data.SqlClient.SqlCommand.RunExecuteReader(CommandBehavior cmdBehavior, RunBehavior runBehavior, Boolean returnStream, String method)\r\n at System.Data.SqlClient.SqlCommand.ExecuteReader(CommandBehavior behavior, String method)\r\n at System.Data.SqlClient.SqlCommand.ExecuteReader()\r\n at ADONET_namespace.ADONET_methods.DisplayTableColumns(String tt) in C:\Documents and Settings\Admin\My Documents\Visual Studio 2008\Projects\AddFileToSQL\AddFileToSQL\ADONET methods.cs:line 35" Where line 35 is dr = cmd.ExecuteReader();

  I have configured the wildcard DNS of *.mydomain.com and it's all working properly. My question is which of these should I rely on identifying client subdomain requests? $_SERVER["HTTP_HOST"] $_SERVER["SERVER_NAME"] $_SERVER["SCRIPT_URI"] They all seem to contain the subdomain part I want but after reading this article by Chris: http://shiflett.org/blog/2005/feb/more-on-filtering-input-and-escaping-output, I'm lost at see and there appears to be no safe way to do this? Any idea on accomplishing this task securely?

• jquery - targetting a select using $this

  - by Maureen

  I am trying to get individual selects (which have the same class as other selects) to respond to a .change function, however it only works on one of the selects. If you test out this code it will make more sense. Try to add a few "ON/OFF events", and then select "Specified Time" in the various selects. You'll see only the first one responds. Any ideas? Thanks! Please see the following code: $(document).ready(function() { var neweventstring = '<div class="event">Turns <select name="ONOFF"><option value="On">ON</option><option value="Off">OFF</option></select> at: <select name="setto" class="setto"><option>Select Time</option><option value="Sunrise">Sunrise</option><option value="Sunset">Sunset</option><option value="specifiedtime">Specified Time</option></select></div>'; $('#addmondaysevent').click(function () { $('#monday .events').append(neweventstring); }); $('.setto').change(function() { alert('The function is called'); if($("option:selected", this).val() =="specifiedtime"){ alert('If returns true'); $(this).css("background-color", "#cc0000"); $(this).after('<div class="specifictime"><input type="text" value="00" style="width:30px"/> : <input type="text" value="00" style="width:30px"> <select name="ampm"><option value="AM" selected>AM</option><option value="PM">PM</option></select></div>') } }); }); And my HTML: <div id="monday"> <h2>Mondays</h2> <div class="events"> <div class="event"> Turn <select name="ONOFF"> <option value="On">ON</option> <option value="Off">OFF</option> </select> at: <select name="setto" class="setto"> <option>Select Time</option> <option value="Sunrise">Sunrise</option> <option value="Sunset">Sunset</option> <option value="specifiedtime">Specified Time</option> </select> </div> [<a id="addmondaysevent">Add an ON/OFF event</a>] </div> </div>

• How do you encourage users to fill out their profile?

  - by mattdell

  Hello, I wanted to open up the topic to discuss ways to encourage or incentivize users to fill in information in a user profile on a website, such as skills, location, organization, etc. More information in a user profile can give a website an improved capability for its users to search, network, and collaborate. Without bugging users to fill in their profiles (ie - via annoying e-mail reminders), what other ways have you guys come up with to encourage user input? Best, -Matt

• Are duplicate directives in php.ini going to cause an issue?

  - by Brandon G

  I sent a request to ops today to update some php.ini directives, and found out that he merely appended them to the end of the file. My google search didn't really come up with any info on whether this is a problem or not to have duplicates in there and how they would be parsed. Obviously, it can cause confusion, but, I would have a stronger argument if I knew if this was acceptable or not. Any input? Thanks in advance...

  Hello, i have this code to get the search resutls from the api: querygoogle.php: <?php session_start(); // Here's the Google AJAX Search API url for curl. It uses Google Search's site:www.yourdomain.com syntax to search in a specific site. I used $_SERVER['HTTP_HOST'] to find my domain automatically.

• How to properly clean up JDBC resources in Java?

  - by user523086

  What is considered best practices when cleaning up JDBC resources and why? I kept the example short, thus just the cleaning up of the ResultSet. finally { if(rs != null) try{ rs.close(); } catch(SQLException ignored) {} } versus finally { try{ rs.close(); } catch(Exception ignored) {} } Personally I favour the second option since it is a bit shorter. Any input on this is much appreciated.
