• "Easiest" way to track unique visitors to a page, in real time?

  - by Cooper

  I need to record in "real time" (perhaps no more than 5 minute delay?) how many unique visitors a given page on my website has had in a given time period. I seek an "easy" way to do this. Preferably the results would be available via a database query. Two things I've tried that failed (so far): Google Analytics: Does the tracking/reporting, but not in real time - results are delayed by hours. Mint Analytics ( http://www.haveamint.com/ ): Tracks in real time, but seems to aggregate data in a way that prevents reporting of unique visitors to a single page over an arbitrary time frame. So, does anyone know how to make Mint Analytics do what I want, or can anyone recommend an analytics package or programmed approach that will do what I need?

• FastCGI has to be restarted for new content to be displayed on my Django site

  - by vorpyg

  I'm currently testing serving my Django site with Nginx, FastCGI and Flup. The server is configured roughly as described in the Django Advent article. I had to do some minor modifications in order to make it work in Ubuntu 9.10. The problem is that when I add new content it doesn't show up on the page before I restart the FastCGI process. I haven't enabled any caching functionality in Django, and when I query the DB from the Django shell it works as expected. Anybody got ideas to what's causing this?

• Interpreting type codes in sys.objects in SQL Server

  - by fatcat1111

  On SQL Server, the sys.objects table includes "Type" and "Type_Desc" attributes. For example: SELECT DISTINCT [Type], Type_Desc FROM Sys.Objects ORDER BY [Type] Returns: C CHECK_CONSTRAINT D DEFAULT_CONSTRAINT F FOREIGN_KEY_CONSTRAINT FN SQL_SCALAR_FUNCTION FS CLR_SCALAR_FUNCTION IT INTERNAL_TABLE P SQL_STORED_PROCEDURE PK PRIMARY_KEY_CONSTRAINT S SYSTEM_TABLE SQ SERVICE_QUEUE TR SQL_TRIGGER U USER_TABLE UQ UNIQUE_CONSTRAINT V VIEW Is there a comprehensive list of these types somewhere? There isn't a constraint on sys.objects that points me to table of these, and sys.types contains data types. I've searched SQL BOL but haven't found it. Any help would be appreciated. EDIT: Some DBs use only a subset of these types. For example, if I have a database with no views, when I query Sys.Objects as above, there are no "V" rows in the results. I am looking for a list of all possible types and descriptions used by SQL Server.

• What is the reason not to use select * ?

  - by Chris Lively

  I've seen a number of people claim that you should specifically name each column you want in your select query. Assuming I'm going to use all of the columns anyway, why would I not use SELECT *? Even considering the question from 9/24, I don't think this is an exact duplicate as I'm approaching the issue from a slightly different perspective. One of our principles is to not optimize before it's time. With that in mind, it seems like using SELECT * should be the preferred method until it is proven to be a resource issue or the schema is pretty much set in stone. Which, as we know, won't occur until development is completely done. That said, is there an overriding issue to not use SELECT *?

• better for-loop syntax for detecting empty sequences?

  - by Dmitry Beransky

  Hi, Is there a better way to write the following: row_counter = 0 for item in iterable_sequence: # do stuff with the item counter += 1 if not row_counter: # handle the empty-sequence-case Please keep in mind that I can't use len(iterable_sequence) because 1) not all sequences have known lengths; 2) in some cases calling len() may trigger loading of the sequence's items into memory (as the case would be with sql query results). The reason I ask is that I'm simply curious if there is a way to make above more concise and idiomatic. What I'm looking for is along the lines of: for item in sequence: #process item *else*: #handle the empty sequence case (assuming "else" here worked only on empty sequences, which I know it doesn't)

• Determining Cross Domain Active Directory Group Membership

  - by thecaptain0220

  I am currently working on a project where I need to query Active Directory to determine group membership of a user. I initially was locating the user and retrieving the memberOf attribute. The problem with this is that there is a domain and a child domain. The groups are universal groups so they can be used in both domains and they don't show up in the memberOf attribute. Unfortunately there doesn't seem to be much info around for Active Directory access with C++. Is there anyway to determine group membership in this case in C++?

• Multiple user database design

  - by dieguitoweb

  I have to develop a basic social network for an academic purpose; but I need some tips for the users management.. The users are subdivided into 3 groups with different privilege: admins,analysts and standards users. For every user should be stored into the database the following information: name,lastname,e-mail,age,password. I'm not quite sure how I should design the database between theese two solutions: 1)one table called 'users' with the 'role' attribute that explain what a user can do and what can't do, and the permissions are managed via php 2)every application user is a database user created with the query 'CREATE ROLE' (It's a postgres database) and he has permissions on some tables granted with the 'GRANT' statement You should take into account that the project is for a database exam.. thanks

• Hibernate, select by id or unique column

  - by Nican

  I am using hibernate for Java, and I want to be able to select users by id or by name from the database. Nice thing about Hibernate is that it caches the result by id, but I seem to be unable to make it cache by name. static Session openSession = Factory.openSession(); public static User GetUser(int Id) { return (User) openSession.get(User.class, new Integer(Id)); } public static User GetUser( String Name ){ return (User) openSession.createCriteria( User.class ). add( Restrictions.eq("username", Name) ). uniqueResult(); } If I use GetUser(1) many times, hibernate will only show that it executed the first time. But every time I use GetUser("user1"), hibernate shows that it is executing a new query to database. What would be the best way to have the string identifier be cached also?

• t-sql - find differences for pk's in a single table (Self join?)

  - by Pace

  Hi Experts, My situation is this. I have a table of products with a pk "Parent" which has "Components" The data looks something like this Parent(PK) Component Car1 Wheel Car1 Tyre Car1 Roof Car2 Alloy Car2 Tyre Car2 Roof Car3 Alloy Car3 Tyre Car3 Roof Car3 Leather Seats Now what I want to do is some query that I can feed two codes in and see the differences... IE If I feed in "Car1", "Car2" it would return something like; Parent Component Car1 Wheel Car2 Alloy As this is the difference between the two. If I said "Car1", "Car3" I would expect; Parent Component Car1 Wheel Car3 Alloy Car3 Leather Seats Your help with this matter would be greatly appreciated.

• How do I do a semijoin using SQLAlchemy?

  - by Jason Baker

  http://en.wikipedia.org/wiki/Relational_algebra#Semijoin Let's say that I have two tables: A and B. I want to make a query that would work similarly to the following SQL statement using the SQLAlchemy orm: SELECT A.* FROM A, B WHERE A.id = B.id AND B.type = 'some type'; The thing is that I'm trying to separate out A and B's logic into different places. So I'd like to make two queries that I can define in separate places: one where A uses B as a subquery, but only returns rows from A. I'm sure this is fairly easy to do, but an example would be nice if someone could show me.

• How to list all items in custom taxonomy with a permanlink in Wordpress

  - by Constant M

  Hi, Not sure how to word this. I've set up a type in Wordpress called Products. I also have two taxonomies linked to Products called Brands and Categories. When you create a product you can set to which Brand and Category the product belong to. It works perfectly when using the type as permalink to list everything within a type http://sitename.com/products but I can't seem to get the taxonomies working in the same way, ie. list all the items within a taxonomy (like an archive, I suppose): http://sitename.com/brands http://sitename.com/categories Is this possible, and if so, what could I possibly be doing wrong? I would try and set up some rewrite rules in functions.php, but I don't know what the query string looks like if you want to list items in a taxonomy, and if this is even possible. If it helps, I'm using the plugins More Types and Ultimate Taxonomy Manager to create the types and taxonomies.

• SQL LIKE question

  - by user176121

  I was wondering if there's a drawback (other than bad practice) to using something like this SELECT * FROM my_table WHERE id LIKE '1'; where id is an integer. I know you're supposed to use id=1 but I am writing a java program and if everything can use LIKE it'll be a lot easier for me. Also, so far, everything works fine; I get the correct query results, so if there is no drawback I will continue doing it like this. edit: I am using MySQL.

• How to search for a string including spaces in Objective C?

  - by AlexCu

  I have a real basic command-line program, in Objective-C, that searches for user inputed information. Unfourtunately, the code will only read the first word in series of words that the user enters. For example, if the user enters in "Apples are great", only "Apples" is kept (and hence searched later on), excluding the "are great" part of the sentence. Here's what I have so far: char enteredQuery [128]; // array 'name' to hold the scanf string NSString *searchQuery; // ending NSString to hold and compare the user inputed data NSLog(@"Enter search query:"); scanf("%s", enteredQuery); //will read the next line searchQuery = [NSString stringWithCString: enteredQuery encoding: NSASCIIStringEncoding]; //converts scanf data into a NSString type I know it's got to do with me using scanf or the character-encoder conversion, but I can't seem to figure it out. Any help in solving the problem is very appreciated! Thanks.

• How can I use cURL to open multiple URLs simultaneously with PHP?

  - by Rob

  Here is my current code: $SQL = mysql_query("SELECT url FROM urls") or die(mysql_error()); //Query the urls table while($resultSet = mysql_fetch_array($SQL)){ //Put all the urls into one variable // Now for some cURL to run it. $ch = curl_init($resultSet['url']); //load the urls curl_setopt($ch, CURLOPT_TIMEOUT, 2); //No need to wait for it to load. Execute it and go. curl_exec($ch); //Execute curl_close($ch); //Close it off } //While loop I'm relatively new to cURL. By relatively new, I mean this is my first time using cURL. Currently it loads one for two seconds, then loads the next one for 2 seconds, then the next. however, I want to make it load ALL of them at the same time. I'm sure its possible, I'm just unsure as to how. If someone could point me in the right direction, I'd appreciate it.

• Accessing inter-schema tables and relations in hibernate

  - by nitesh

  There is a typical situation being faced where different tables are scattered through different schemas in Oracle database and they are related to each other (encompassing all different types of relations). How can they be represented in Hibernate using annotations as when a sessionfactory handle is created for one schema, tables in that schema can't access other related tables (foreign key relation to tables in other schema)? For a query like following, exception is thrown - "from table1 as model where model.table2Name.table2column = "+foo Exception comes as - org.hibernate.QueryException: could not resolve property: table2column of: com.test.table1 [from com.test.table1 as model where model.table2Name.table2column = 1] Here table1 and table2 are present in different schemas.

• Anyway to find out the current Windows is in lock mode?

  - by David.Chu.ca

  I have a windows application written in VS 2005. The application makes queries against to sql database in a timer cycle every 2 minutes. If there any data changes, the window will be refreshed with new data. If the user leaves the window, the windows will be automatically locked after a while. There is no sense to keep querying data in ever 2 minutes when the windows is locked; therefore I would like to stop the query when lock is on so that the network data trafic will be reduced and also saves the current windows resources such as memory and CPUs. I am not sure if there is any way to find out the current windows is locked? Not sure if there is any Windows APIs for this purpose if no .Net classes available? My project is in .Net 2.0 and all users are in Windows XP.

• Send 404 when requesting index.php through .htaccess?

  - by Daniel

  I've recently refactored an existing CodeIgniter application to use url segments instead of query strings, and I'm using a rewriterule in htaccess to rewrite stuff to index.php: RewriteRule ^(.*)$ /index.php/$1 [L] My problem right now is that a lot of this website's pages are indexed by google with a link to index.php. Since I made the change to use url segments instead, I don't care about these google results anymore and I want to send a 404 (no need to use 301 Move permanently, there have been enough changes, it'll just have to recrawl everything). To get to the point: How do I redirect requests to /index.php?whatever to a 404 page? I was thinking of rewriting to a non-existent file that would cause apache to send a 404. Would this be an acceptable solution? How would the rewriterule for that look like? edit: Currently, existing google results will just cause the following error: An Error Was Encountered The URI you submitted has disallowed characters.

• Checking for 2 exepcted values in Junit

  - by Swift-Tuttle

  Hi, I have a java program which throws an exception with 2 different messages for 2 different scenarios and I want the Junit test case to check for equality for both of these messages. As an example - public void amethod() { // do some processing if(scenario1 == true) { throw new MySystemException("An error occured due to case 1 being incorrect."); } else if(scenario2 == true) { throw new MySystemException("An error occured as case 2 could not be found"); } } Now the JUnit for this would be something like- public void testAMethod() { // do something assertEquals("Expected", "Actual"); } As I understand, in this above example, if I use the Scenario1 exception message the junit will fail when an exception is thrown for Scenario2 and vice versa. I would like to know if there is any other way provided in Junit by which I can use this one test method and check for both the messages for the test to pass? Something like an OR, if possible to provide the "Expected" value with both these expected message. I hope my query is clear enough. Thanks

• pass parameter from controller to models condition

  I'm trying to bind a param to a join via a named scope., but I'm getting an error. What is the correct way to do that? has_one :has_voted, :class_name => 'Vote', :conditions => ['ip = :userIp'] # named scopes scope :with_vote, lambda {|ip| { :include => [:has_voted], # like this ?? :conditions => [:has_voted => {:conditions => {:userIp => ip}} ] }} Idea.with_vote(request.ip).all I believe I need the condition definition in the model for it to appear in the ON clause of a JOIN, rather then in the WHERE one. Edit I'm trying to get the following query select Ideas.*, Votes.* from Ideas left outer join Votes on Votes.Idea_id = Idea.id AND Votes.ip = {request.ip}

• WCF methods sharing a dictionary

  - by YeomansLeo

  I'm creating a WCF Service Library and I have a question regarding thread-safety consuming a method inside this library, here is the full implementation that I have until now. namespace WCFConfiguration { [ServiceBehavior(InstanceContextMode = InstanceContextMode.PerCall, ConcurrencyMode = ConcurrencyMode.Single)] public class ConfigurationService : IConfigurationService { ConcurrentDictionary<Tuple<string,string>, string> configurationDictionary = new ConcurrentDictionary<Tuple<string,string>, string>(); public void Configuration(IEnumerable<Configuration> configurationSet) { Tuple<string, string> lookupStrings; foreach (var config in configurationSet) { lookupStrings = new Tuple<string, string>(config.BoxType, config.Size); configurationDictionary.TryAdd(lookupStrings, config.RowNumber); } } public void ScanReceived(string boxType, string size, string packerId = null) { } } } Imagine that I have a 10 values in my configurationDictionary and many people want to query this dictionary consuming ScanReceived method, are those 10 values be shared for each of the clients that request ScanReceived? Do I need to change my ServiceBehavior? The Configuration method is only consumed by one person by the way.

• Update int array based on parent

  - by Pickels

  I have the following int[] in my database: '{0}' '{0,0}' '{0,0,0}' '{0,0,0,0}' This column is used to sort my tree data. Now when a parent updates it's order the children should also update. For example if the second record updates it's order to 1 it should result in the following. '{0}' '{0,1}' '{0,1,0}' '{0,1,0,0}' So I was wondering what the query would be to update record 3 and 4. In case it's not clear what I am asking leave a comment I can add additional information. Screenshot of my actual data:
