  • Best way to track impressions/clicks in a bespoke advertisement system?

    - by Martin Bean
    I've been asked to create a bespoke advertisement system despite suggesting open source alternatives such as OpenX and DoubleClick for Publishers (the former Google Ad Manager). I've got the basics of the system set up, i.e. uploading creatives, creating positions and a mechanism to place creatives within positions; however, the area I'm stuck with is impression and click tracking. At the moment an impression and click is stored with the creative, but this then means impressions/clicks can't be queried. For example, we can't find how many impressions were in position x between date y and date z. How would I go about storing that kind of data? My theory was store the creative ID, position ID and timestamp in a database table, but given the amount of traffic the site has this would produce a very large database very quickly. If any one could give me a pointer or two, that would be great.

  • How do I access a file share programattically

    - by Mykroft
    I have a windows forms app running on a machine that is not on a domain, that needs to be able to move a file from the local filesystem to a UNC path. I have a username and password for that path. I was wondering is there any way to do this directly with out execing the net.exe command? Ideally I wouldn't have to map a drive.

  • Git repositories on shared hosting with ssh access - multiple users / one ssh account

    - by acp
    I'm part of a small team trying to start coding on a project. I've decided it's time to give git a chance (no more svn) and was trying to see if we could use our shared web hosting to deploy a "public" repository there so that we can easily push/pull to/from it and keep up-to-date with each others changes. The problem I'm having now is that we only have a single ssh account for that hosting. Having used svn in the past, I could enforce a svn username on a given pair of ssh keys, however I don't seem to be able to do something similar with git (in other words tie the ssh keypair to a specific dev). I don't mind everybody having read/write permissions everywhere, since anything that is private should stay on each others machine. Finally, solutions such as gitosis can not be used. I guess my question to you is how is accountability to git pushes given? Is it tied to the ssh account being used, or the email address given in git config? Can I create different ssh keys for every developer (for the same ssh account though), and just send them to the devs?

  • Best database (mysql) structure for this case:

    - by robert
    we have three types of data (tables): Book (id,name,author...) ( about 3 million of rows) Category (id,name) ( about 2000 rows) Location (id,name) ( about 10000 rows) A Book must have at least 1 type of Category (up to 3) AND a Book must have only one Location. I need to correlate this data to get this query faster: Select Books where Category = 'cat_id' AND Location = 'loc_id' Select Books where match(name) against ('name of book') AND Location = 'loc_id' Please I need some help. Thanks

  • sql server 2005 replication article conflict

    - by Daniel
    Hi all, I have a sql server 2005 database that I want to setup replication for. The problem is that the database has two schemas both of which have a table with the same name in it. For some reason even though the tables are in different schemas the replication creation fails when done through management studio due to conflicting article names (i assume its trying to create the same name for both tables in the different schemas). Is there any workaround for doing this in the studio, I can probably write a script or program to do this but just for this one thign is a bit annoying and it probably wont be allowed to run in production. Perhaps there is a hot fix or something I'm not aware about? Cheers,

  • Search-friendly way to store checkbox values in MySQL?

    - by Alex
    What is a search-friendly way to store checkbox values in the database? Currently, checkboxes are processed as an array and values are separated by a ";" As such: <input type="checkbox" name="frequency[]" value="Daily"/> Daily <input type="checkbox" name="frequency[]" value="Weekly"/> Weekly <input type="checkbox" name="frequency[]" value="Monthly"/> Monthly The PHP backend runs implode(';', $frequency) and adds the string to the database. This works fine but it's a nightmare when it comes to searching. Is there a better way to approach this?

  • Controlling read and write access width to memory mapped registers in C

    - by srking
    I'm using and x86 based core to manipulate a 32-bit memory mapped register. My hardware behaves correctly only if the CPU generates 32-bit wide reads and writes to this register. The register is aligned on a 32-bit address and is not addressable at byte granularity. What can I do to guarantee that my C (or C99) compiler will only generate full 32-bit wide reads and writes in all cases? For example, if I do a read-modify-write operation like this: volatile uint32_t* p_reg = 0xCAFE0000; *p_reg |= 0x01; I don't want the compiler to get smart about the fact that only the bottom byte changes and generate 8-bit wide read/writes. Since the machine code is often more dense for 8-bit operations on x86, I'm afraid of unwanted optimizations. Disabling optimizations in general is not an option.

  • Suggestion on Database structure for relational data

    - by miccet
    Hi there. I've been wrestling with this problem for quite a while now and the automatic mails with 'Slow Query' warnings are still popping in. Basically, I have Blogs with a corresponding table as well as a table that keeps track of how many times each Blog has been viewed. This last table has a huge amount of records since this page is relatively high traffic and it logs every hit as an individual row. I have tried with indexes on the fields that are included in the WHERE clause, but it doesn't seem to help. I have also tried to clean the table each week by removing old ( 1.weeks) records. SO, I'm asking you guys, how would you solve this? The query that I know is causing the slowness is generated by Rails and looks like this: SELECT count(*) AS count_all FROM blog_views WHERE (created_at >= '2010-01-01 00:00:01' AND blog_id = 1); The tables have the following structures: CREATE TABLE IF NOT EXISTS 'blogs' ( 'id' int(11) NOT NULL auto_increment, 'name' varchar(255) default NULL, 'perma_name' varchar(255) default NULL, 'author_id' int(11) default NULL, 'created_at' datetime default NULL, 'updated_at' datetime default NULL, 'blog_picture_id' int(11) default NULL, 'blog_picture2_id' int(11) default NULL, 'page_id' int(11) default NULL, 'blog_picture3_id' int(11) default NULL, 'active' tinyint(1) default '1', PRIMARY KEY ('id'), KEY 'index_blogs_on_author_id' ('author_id') ) ENGINE=InnoDB DEFAULT CHARSET=utf8 AUTO_INCREMENT=1 ; And CREATE TABLE IF NOT EXISTS 'blog_views' ( 'id' int(11) NOT NULL auto_increment, 'blog_id' int(11) default NULL, 'ip' varchar(255) default NULL, 'created_at' datetime default NULL, 'updated_at' datetime default NULL, PRIMARY KEY ('id'), KEY 'index_blog_views_on_blog_id' ('blog_id'), KEY 'created_at' ('created_at') ) ENGINE=InnoDB DEFAULT CHARSET=utf8 AUTO_INCREMENT=1 ;

  • Order objects for Northwind Access database

    - by Artem Shnayder
    I need to build two objects: an OrderList and an Order. Using those two objects, I have to populate a DataGridView with a history of the orders. However, I am instructed not to use binding sources for the connection or other drag and drop controls. Unfortunately, from Google it seems like those are the most popular options for this type of problem. Can anyone point me in the right direction? I don't have much experience with C#. Thanks.

  • Zend Database Adapter - Complex MySQL Query

    - by Sonny
    I have defined a function in my Navigation model that executes a query, and I was wondering if there's a more "Zendy" way of generating/executing the query. The query I'm using was proposed by Bill Karwin on another thread here for setting arbitrary record order. I tried using a prepared statement, but the values in the SIGN() function got quoted. I'm using the PDO adapter for MySQL. /** * */ public function setPosition($parentId, $oldPosition, $newPosition) { $parentId = intval($parentId); $oldPosition = intval($oldPosition); $newPosition = intval($newPosition); $this->getAdapter()->query(" UPDATE `navigation` SET `position` = CASE `position` WHEN $oldPosition THEN $newPosition ELSE `position` + SIGN($oldPosition - $newPosition) END WHERE `parent_id` = $parentId AND `position` BETWEEN LEAST($oldPosition, $newPosition) AND GREATEST($oldPosition, $newPosition) "); return $this; }

  • primary key datatype in sql server database

    - by ooo
    i see after installing the asp.net membership tables, they use the data type "uniqueidentifier" for all of the primary key fields. I have been using "int" data type and doing increment by one on inserts. Is there any particular benefits to using the uniqueIdentifier data type compared to my current model of using int and auto increments on new inserts ?

  • Visual SourceSafe (VSS): "Access to file (filename) denied" error

    - by tk-421
    Hi, can anybody help with the above SourceSafe error? I've spent hours trying to find a fix. I've also Googled the heck out of it but couldn't find a scenario matching mine, because in my case only a few files (not all) are affected. Here's what I found: only a few files in my project generate this error other files in the same directory (for example, App_Code has one of the problem files) work fine I've tried checking out from both the VSS client and Visual Studio another developer can check out the main problem file without any problems This sounds like a permission issue for my user, right? However: I found the location of one of the problem files in VSS's data directory (using VSS's naming format, as in 'fddaaaaa.a') and checked its permissions; everything looks fine and its permissions match those of other files I can check out successfully I can see no differences in the file properties between working and non-working files What else can I check? Has anyone encountered this problem before and found a solution? Thanks. P.S.: SourceGear, svn or git are not options, unfortunately. P.P.S.: Tried unsuccessfully to add tag "sourcesafe." EDIT: Hey Paddy, I tried to click 'add comment' to respond to your comment, but I'm getting a javascript error when loading this page in IE8 ("jquery undefined," etc.) so this isn't working. This is when checking out files, and yes, I've obliterated my local copy more times than I can remember. ;) EDIT 2: Thanks for the responses, guys (again I can't 'add comment' due to jQuery not loading, maybe blocked as discussed in Meta). If the problem was caused by antivirus or a bad disk, would other users still be able to check out the file(s)? That's the case here, which makes me think it's a permission issue specific to my account. However I've looked at the permissions and they match both other users' settings and settings on other files which I can check out.

  • C# Unit Testing - Generating Mock DataContexts / LINQ -> SQL classes

    - by gav
    Hi All, I am loving the new world that is C#, I've come to a point with my toy programs where I want to start writing some unit tests. My code currently uses a database via a DatabaseDataContext object (*.dbml file), what's the best way to create a mock for this object? Given how easy it is to generate the database LINQ - SQL code and how common a request this must be I'm hoping that VS2010 has built in functionality to help with testing. If I'm way off and this must be done manually could you please enlighten me as to your preferred approach? Many Thanks, Gavin

  • CommandName issues to insert to a database

    In the below code, when we define the parameters CommandName="Insert" is it actually the same as executing the method Insert?

  • 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.

  • how to prevent database to add slash to quotes

    - by black sensei
    i know this sounds really common and so trivial but , am having a challenge here. I have a web site with Zend/Doctrine and i use ckeditor for the backend management. after uploading the site i've realized that during edit testing the look and feel of the site is messed up. with the help of firebug, i've seen that there are slashes all over the html. after inline edition, the look and feel came back to normal. There are so many files , i can't think of doing other decoding before outputting data from mysql. What options do i have to solve this problem. the site is up already and i feel a bit unconfortable about this. Can anyone give a hint? thanks

  • SimpleDB direct client access

    - by AlexJReid
    One of the useful things about S3 for content storage is that a client can directly make a direct HTTP request to download the object. For instance, this is how Twitter serve up avatar images. SimpleDB provides an HTTP interface to data. Rather than having to write a proxy that sits inbetween SimpleDB and the client, is it possible for client software (i.e. desktop, mobile) to make calls to read values from a SimpleDB domain, without sharing credentials that shouldn't be shared? Or is a proxy in-between the only way to go?
