• iPhone rotation woes

  - by skooter500

  I have been spending many frustrating hours trying to get rotations working on the iPhone version of Tunepal. Firstly, I have a tab bar controller, with a navigation controller controlling each of the views. I actually only want one of my views to be able to rotate and that is the TuneDisplay. I have a subclassed the UITabBarController and overridden theshouldAutorotateToInterfaceOrientation: (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation) interfaceOrientation { if (self.selectedViewController != nil) { return [self.selectedViewController shouldAutorotateToInterfaceOrientation:interfaceOrientation]; } else { return (interfaceOrientation == UIInterfaceOrientationPortrait); } } In each of the view controllers for each of the tabs I have overridden the method and returned YES for each orientation I want to support. All well and good and everything works as it should. If I try and do a rotation on a tab that doesn’t support the rotation, nothing happens. The problem occurs if I move from a tab thats rotated to a tab that isnt supposed to support that rotation. The new tab is displayed rotated too! Screenshots for all this are included here: http://tunepal.wordpress.com/2010/04/20/rotation-woes/ Is there any way I can make it rotate back to portrait on tapping the tab? I have tried the unsupported setOrientation trick, but firstly it doesnt work correctly and secondly I received a warning from Apple for including it in my last build. If (as I suspect) there is no way to limit this behavior: How do I make the microphone image scale when I rotate the device? How do I make the buttons and the progress bar expand to fit the witdh of the toolbar? Also, one of the tabs that rotates ok has a table, with a search bar. The first time I rotate to the right or to the left, I get a black bar to the right of the search bar. If I subsequently rotate back and rotate again, the bar disappears! I have enabled the struts and springs things on the search bar in the interface builder and it looks like it should behave correctly. Any ideas about how to fix this? Ideas, feedback much appreciated Bryan

• How can I improve this SQL to avoid several problems with its results?

  - by Josh Curren

  I am having some problems with trying to search. Currently this will only return results that have at least 1 row in the maintenance_parts table. I would like it to return results even if there are 0 parts rows. My second problem is that when you search for a vehicle and it should return multiple results (multiple maintenance rows) it will only return 1 result for that vehicle. Some Background Info: The user has 2 fields to fill out. The fields are vehicle and keywords. The vehicle field is meant to allow searching based on the make, model, VIN, truck number (often is 2 - 3 digits or a letter prefix followed by 2 digits), and a few other fields that belong to the truck table. The keywords are meant to search most fields in the maintenance and maintenance_parts tables (things like the description of the work, parts name, parts number). The maintenance_parts table can contain 0, 1, or more rows for each maintenance row. The truck table contains exactly 1 row for every maintenance row. A truck can have multiple maintenance records. "SELECT M.maintenance_id, M.some_id, M.type_code, M.service_date, M.mileage, M.mg_id, M.mg_type, M.comments, M.work_done, MATCH( M.comments, M.work_done) AGAINST( '$keywords' ) + MATCH( P.part_num, P.part_desc, P.part_ref) AGAINST( '$keywords' ) + MATCH( T.truck_number, T.make, T.model, T.engine, T.vin_number, T.transmission_number, T.comments) AGAINST( '$vehicle' ) AS score FROM maintenance M, maintenance_parts P, truck T WHERE M.maintenance_id = P.maintenance_id AND M.some_id = T.truck_id AND M.type_code = 'truck' AND ( (MATCH( T.truck_number, T.make, T.model, T.engine, T.vin_number, T.transmission_number, T.comments) AGAINST( '$vehicle' ) OR T.truck_number LIKE '%$vehicle%') OR MATCH( P.part_num, P.part_desc, P.part_ref) AGAINST( '$keywords' ) OR MATCH( M.comments, M.work_done) AGAINST( '$keywords' ) ) AND M.status = 'A' GROUP BY maintenance_id ORDER BY score DESC, maintenance_id DESC LIMIT 0, $limit"

• How can I make PHP scripts timeout gracefully while waiting for long-running MySQL queries?

  - by Mark B

  I have a PHP site which runs quite a lot of database queries. With certain combinations of parameters, these queries can end up running for a long time, triggering an ugly timeout message. I want to replace this with a nice timeout message themed according to the rest of my site style. Anticipating the usual answers to this kind of question: "Optimise your queries so they don't run for so long" - I am logging long-running queries and optimising them, but I only know about these after a user has been affected. "Increase your PHP timeout setting (e.g. set_time_limit, max_execution_time) so that the long-running query can finish" - Sometimes the query can run for several minutes. I want to tell the user there's a problem before that (e.g. after 30 seconds). "Use register_tick_function to monitor how long scripts have been running" - This only gets executed between lines of code in my script. While the script is waiting for a response from the database, the tick function doesn't get called. In case it helps, the site is built using Drupal (with lots of customisation), and is running on a virtual dedicated Linux server on PHP 5.2 with MySQL 5.

• .htaccess - alias all www-only requests to subdirectory

  - by CodeMoose

  Trying to install the wonderful Concrete5 CMS to use as my main site engine - the problem is it has about 15 different files and directories, and they clutter up my root. I'd really like to move it to a /_concrete/ subdirectory, and still maintain it in the domain root. htaccess has never been my strong suit - after a lot of research and learning, and a lot of error 500s, my frustration is overriding my pride and I'm posting here. Here's exactly what I'm trying to accomplish: Any requests that come through www.domain.com are forwarded to www.domain.com/_concrete/, except in the case of an existing file. The end-user URL shouldn't change - they will still see the site as www.domain.com, even though they're being served www.domain.com/_concrete/. Multiple subdomains exist on this site as sub-folders within the root - thus, only requests coming through www.domain.com should be redirected. Here's the closest I got with my htaccess, which produces an error 500: RewriteEngine On RewriteCond %{HTTP_HOST} ^(www\.)?domain\.com [NC] RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !^_concrete RewriteRule ^(.*)$ _concrete/$1 [L,QSA] This is the result of 4 hours of sweat and blood (mostly blood), so I have to be close. I'm hoping one of your fine minds can point out a stupid mistake and put this thing to rest swiftly. Thanks for your time! Addendum: I previously posted .htaccess - alias domain root to subfolder a while ago, which got me started. Please don't fall into the trap of thinking it's a duplicate.

• Is there a maximum number of input controls that can be used on an HTML form?

  - by Rich

  I have an ambitious requirement for an asp.net 2.0 web page that contains a table (gridview), and each row in the grid contains 6 select (dropdown) controls for data entry. The number of rows that will be displayed is dependent upon the user's search parameters, which are specified in another area of the page. Unfortunately, with the default (and even basic) search parameters specified, the grid could contain several hundred rows. I've noticed that the browser, in this case IE8, starts behaving rather erratically once I reach a large number of rows -- no documented evidence for the number of rows where this begins to be a problem. For example, trying to view the source of the page results in a message from IE stating that there was a problem with the page that forced the browser to reload it, and I never get the source. Obviously the page loads and renders rather slowly also. I know that my solution is probably going to involve paging the gridview such that it only displays 20 or so rows per page, and I'll have to write code to handle the saving of changes in the dropdown values when the user changes pages. I can probably turn off viewstate on the gridview also. However, the question I really want to pose is this -- has anyone seen a documented rule indicating the maximum number of input controls that an HTML browser form is supposed to be able to contain? I could not find anything on the Internet after doing a search, and I suspect the answer may be whatever the browser can handle based on the machine configuration it is running on. Any rules of thumb you use? Thanks for any suggestions. Rich

• Python script not working when run from browser directly

  - by splatterdash

  I'm trying to run this script: import re, os def build_pool(cwd): global xtn_pool, file_pool xtn, xtn_pool = re.compile('\\.[0-9a-zA-Z]{1,4}$'), [] file_pool = [files for files in os.listdir(cwd) if os.path.isfile(files) and xtn.search(files)] # Lists all the file extension in the folder for file in file_pool: if not xtn_pool.__contains__(xtn.search(file).group()): xtn_pool.append(xtn.search(file).group()) return xtn_pool.sort(), file_pool if __name__ == '__main__': import sys #if path is given, change working directory to path if len(sys.argv) >= 2: os.chdir(sys.argv[1]) build_pool(os.getcwd()) #if no path is given when running, do renaming in current folder else: build_pool(os.getcwd()) print('The folder contains the following extensions: ') for i in range(0, len(xtn_pool)): print(repr(i+1) + '.

')) xtn_pick = xtn_pool[opt-1] # Lists all the file with the chosen extension xtn_file_pool = [file for file in file_pool if file.endswith(xtn_pick)] print('There are {0} files with the {1} extension.'.format(len(xtn_file_pool), xtn_pick)) xtn_new = input('Input replacement extension: ') # The actual renaming process for file in xtn_file_pool: os.rename(file, file[:-len(xtn_pick)+1] + xtn_new) directly from my file browser (Nautilus), but for some reason it's not working. When I run it from terminal (python3 scriptname.py) it works fine as intended. But when I just click the script file in Nautilus, choose 'Run in Terminal', it always stops after asking 'Input replacement extension: '. How can I make this script run without using the terminal?

• Where to start with the development of first database driven Web App (long question)?

  - by Ryan

  Hi all, I've decided to develop a database driven web app, but I'm not sure where to start. The end goal of the project is three-fold: 1) to learn new technologies and practices, 2) deliver an unsolicited demo to management that would show how information that the company stores as office documents spread across a cumbersome network folder structure can be consolidated and made easier to access and maintain and 3) show my co-workers how Test Drive Development and prototyping via class diagrams can be very useful and reduces future maintenance headaches. I think this ends up being a basic CMS to which I have generated a set of features, see below. 1) Create a database to store the site structure (organized as a tree with a 'project group'-project structure). 2) Pull the site structure from the database and display as a tree using basic front end technologies. 3) Add administrator privileges/tools for modifying the site structure. 4) Auto create required sub pages* when an admin adds a new project. 4.1) There will be several sub pages under each project and the content for each sub page is different. 5) add user privileges for assigning read and write privileges to sub pages. What I would like to do is use Test Driven Development and class diagramming as part of my process for developing this project. My problem; I'm not sure where to start. I have read on Unit Testing and UML, but never used them in practice. Also, having never worked with databases before, how to I incorporate these items into the models and test units? Thank you all in advance for your expertise.

• How to explain to client that you can't give them some of the source

  - by Bo

  We have a number of AS/Flex components that we've built over time and improved upon. They've been turned into components so they can be reused in different projects and save us time. So you can think of them as part of an in-house framework of sorts. We're now realizing that it doesn't make sense to release the source code for these components to the various clients as part of the project, because technically this code isn't really owned by the clients. So my question When a client comes to you, how do you explain to them that you can't give them the full source code for those components. The client doesn't understand the difference, he just expects you to give them all the code for the site that he paid you to do. He doesn't understand that this code has taken you a lot longer to write than what he's paying for his site. But since he doesn't understand, he would get turned off and thinks you're ripping him off or something. How do you handle this situation? What do you tell clients upfront? Do you advertise it on your site from the very beginning? How do you handle their objections so they still hire you? As a side question, how often do you give AS and Flex source code to your clients? In the case when the code doesn't have any in-house components that you reuse in several projects, and in the case when it does have in-house components.

• Apache's AuthDigestDomain and Rails Distributed Asset Hosts

  - by Jared

  I've got a server I'm in the process of setting up and I'm running into an Apache configuration problem that I can not get around. I've got Apache 2.2 and Passenger serving a Rails app with distributed asset hosting. This is the feature of Rails that lets you serve your static assets from assets0.example.com, assets1, assets2, and so on. The site needs to be passworded until launch. I've set up HTTP authentication on the site using Apache's mod_auth_digest. In my configuration I'm attempting to use the AuthDigestDomain directive to allow access to each of the asset URLs. The problem is, it doesn't seem to be working. I get the initial prompt for the password when I load the page, but then the first time it loads an asset from one of the asset URLs, I get prompted a 2nd, 3rd, or 4th time. In some browsers, I get prompted for every single resource on the page. I'm hoping that this is only a problem of how I'm specifying my directives and not a limitation of authorization in Apache itself. See the edited auth section below: <Location /> AuthType Digest AuthName "Restricted Site" AuthUserFile /etc/httpd/passwd/passwords AuthGroupFile /dev/null AuthDigestDomain / http://assets0.example.com/ http://assets1.example.com/ http://assets2.example.com/ http://assets3.example.com/ require valid-user order deny,allow allow from all </Location>

• Optimizing landing pages

  - by Oleg Shaldybin

  In my current project (Rails 2.3) we have a collection of 1.2 million keywords, and each of them is associated with a landing page, which is effectively a search results page for a given keywords. Each of those pages is pretty complicated, so it can take a long time to generate (up to 2 seconds with a moderate load, even longer during traffic spikes, with current hardware). The problem is that 99.9% of visits to those pages are new visits (via search engines), so it doesn't help a lot to cache it on the first visit: it will still be slow for that visit, and the next visit could be in several weeks. I'd really like to make those pages faster, but I don't have too many ideas on how to do it. A couple of things that come to mind: build a cache for all keywords beforehand (with a very long TTL, a month or so). However, building and maintaing this cache can be a real pain, and the search results on the page might be outdated, or even no longer accessible; given the volatile nature of this data, don't try to cache anything at all, and just try to scale out to keep up with traffic. I'd really appreciate any feedback on this problem.

• sqlobject: No connection has been defined for this thread or process

  - by Claudiu

  I'm using sqlobject in Python. I connect to the database with conn = connectionForURI(connStr) conn.makeConnection() This succeeds, and I can do queries on the connection: g_conn = conn.getConnection() cur = g_conn.cursor() cur.execute(query) res = cur.fetchall() This works as intended. However, I also defined some classes, e.g: class User(SQLObject): class sqlmeta: table = "gui_user" username = StringCol(length=16, alternateID=True) password = StringCol(length=16) balance = FloatCol(default=0) When I try to do a query using the class: User.selectBy(username="foo") I get an exception: ...

• Trouble recording unique regex output to array in perl

  - by Structure

  The goal of the following code sample is to read the contents of $target and assign all unique regex search results to an array. I have confirmed my regex statement works so I am simplifying that so as not to focus on it. When I execute the script I get a list of all the regex results, however, the results are not unique which leads me to believe that my manipulation of the array or my if (grep{$_ eq $1} @array) { check is causing a problem(s). #!/usr/bin/env perl $target = "string to search"; $inc = 0; $once = 1; while ($target =~ m/(regex)/g) { #While a regex result is returned if ($once) { #If $once is not equal to zero @array[$inc] = $1; #Set the first regex result equal to @array[0] $once = 0; #Set $once equal to zero so this is not executed more than once } else { if (grep{$_ eq $1 } @array ) { #From the second regex result, check to see if the result is already in the array #If so, do nothing } else { @array[$inc] = $1; #If it is not, then assign the regex search result to the next unused position in the array in any position. $inc++; #Increment to next unused array position. } } } print @array; exit 0;

• Django - Problem with models/manager to organise a query...

  - by user296644

  Hi, I have an application to count the number of access to an object for each website in a same database. class SimpleHit(models.Model): """ Hit is the hit counter of a given object """ content_type = models.ForeignKey(ContentType) object_id = models.PositiveIntegerField() content_object = generic.GenericForeignKey('content_type', 'object_id') site = models.ForeignKey(Site) hits_total = models.PositiveIntegerField(default=0, blank=True) [...] class SimpleHitManager(models.Manager): def get_query_set(self): print self.model._meta.fields qset = super(SimpleHitManager, self).get_query_set() qset = qset.filter(hits__site=settings.SITE_ID) return qset class SimpleHitBase(models.Model): hits = generic.GenericRelation(SimpleHit) objects = SimpleHitManager() _hits = None def _db_get_hits(self, only=None): if self._hits == None: try: self._hits = self.hits.get(site=settings.SITE_ID) except SimpleHit.DoesNotExist: self._hits = SimpleHit() return self._hits @property def hits_total(self): return self._db_get_hits().hits_total [...] class Meta: abstract = True And I have a model like: class Model(SimpleHitBase): name = models.CharField(max_length=255) url = models.CharField(max_length=255) rss = models.CharField(max_length=255) creation = AutoNowAddDateTimeField() update = AutoNowDateTimeField() So, my problem is this one: when I call Model.objects.all(), I would like to have one request for the SQL (not two). In this case: one for Model in order to have information and one for the hits in order to have the counter (hits_total). This is because I cannot call directly hits.hits_total (due to SITE_ID?). I have tried select_related, but it seems to do not work... Question: - How can I add column automatically like (SELECT hits.hits_total, model.* FROM [...]) to the queryset? - Or use a functional select_related with my models? I want this model could be plugable on all other existing model. Thank you, Best regards.

• How do I extract specific data with preg_match?

  I'm looking to extract values from a whole load of html (i've just trimmed down to the relevant data), there are multiple 'select' elements, and only want to extract those who's 'name' element matches the name 'aMembers'. So the resulting values I would like to retrieve are 5,10,25 and 30 (see below) how can I achieve this with preg_match? <DIV id="searchM" class="search"><select name="aMembers" id="aMembers" tabIndex="2"> <option selected="selected" value="">Data 3</option> <option value="5">A name</option> <option value="10">Another name</option> </select> </DIV> <DIV id="searchM" class="search"><select name="bMembers" id="bMembers" tabIndex="2"> <option selected="selected" value="">Data 2</option> <option value="15">A name</option> <option value="20">Another name</option> </select> </DIV> <DIV id="searchM" class="search"><select name="aMembers" id="Members" tabIndex="2"> <option selected="selected" value="">Data 1</option> <option value="25">A name</option> <option value="30">Another name</option> </select> </DIV>

• PHP download page: file_exists() returns true, but browser returns 'page not found'

  - by Chris

  I'm using PHP for a file download page. Here's a snippet of the problem code: if (file_exists($attachment_location)) { header($_SERVER["SERVER_PROTOCOL"] . " 200 OK"); header("Cache-Control: public"); // needed for i.e. header("Content-Type: application/zip"); header("Content-Transfer-Encoding: Binary"); header("Content-Length:".filesize($attachment_location)); header("Content-Disposition: attachment; filename=file.zip"); readfile($attachment_location); die("Hooray"); } else { die("Error: File not found."); } This code works absolutely fine when testing locally, but after deploying to the live server the browser returns a 'Page not found' error. I thought it might be an .htaccess issue, but all .htaccess files on the live server are identical to their local counterparts. My next guess would be the live server's PHP configuration, but I have no idea what PHP setting might cause this behaviour. The file_exists() function always returns true - I've checked this on the live server and it's always correctly picking up the file, its size etc., so it does have a handle on the file. It just won't perform the download! The main site is a Wordpress site, but this code isn't part of a Wordpress page - it's in a standalone directory within the site root. UPDATE: is_file() and is_readable() are both returning true for the file, so that's not the problem. The specific line that is causing the problem is: readfile($attachment_location) Everything up until that point is super happy.

• Where is a small, simple CMS that has no Front End done in PHP?

  - by user559469

  The keys are: small and simple PHP MySql no Front End By "no front end" I mean literally, I can control the look 100%. I just want a CMS on the "backend" to manage content (user login/security, upload images, udate articles, etc.) that will not dictate in anyway how the managed data is presented. Maybe it just keeps the info in a (MySql) database (which I can query and extract myself) or if it writes content, it is in super-clean xhtml fragments or even just xml I will parse myself? I have looked at Wordpress -- and don't like the code it generates, not to mention the sites look too "canned" (you can usually spot a WP site a mile a way.) Joomla and Drupal look more customizable, but they are bloated now in my opinion, and really I just want something lightweight and simple. For one-user mom-and-pop sites. (No tiered publishing/approval systems, and all that.) I envision plugging this CMS into existing websites/web apps where most of the site is made and managed by me, but a few choice areas are managed by the site owner.

  I have a web page that when I run it on a remote computer I get the message saying that remote errors cannot be viewed When I go to view it on my web server machine, I get a message saying: Internet Explorer cannot display the webpage • Most likely causes: • You are not connected to the Internet. • The website is encountering problems. • There might be a typing error in the address. What you can try: Check your Internet connection. Try visiting another website to make sure you are connected. Retype the address. Go back to the previous page. I can get to google fine, so it is not the internet connection.... But this message gives me nothing to work on. How can I get more info as to why my page is not working? I tried going to IIS Mananger and right clicking on the site and selecting browse. But my site is an HTTPS site so that does not work. Any ideas would be great.

• JQuery Control Update Not Happening

  - by Mad Halfling

  Hi, I've got a script that disables a button input control, empties a table body and then (after an AJAX call) re-populates it. It all works fine but sometimes there are a lot of rows in the table so the browser (IE) takes a while to empty and refill it. The strange thing is, while the rows are being emptied, the button still appears to be enabled, however if I put an alert between the button being disabled and the tbody being emptied, the button works properly, disabling visibly before the the alert comes up. Is there any way I can get the button to update before the resource consuming table emptying process/command commences? Thx MH Code sample, as requested (but it's not complex, so I didn't initially include it) $('#Search').attr('disabled', true); $('#StatusSpan').empty(); $('#DisplayTBody').empty(); then I perform my AJAX call, re-enable the button and repopulate the table. As I mentioned, normally this is really quick and isn't a problem, but if there are, say, 1500 rows in the table it takes a while to clear down but the 'Search' button doesn't update on the screen, however if I put an alert after the .attr('disabled' line the button visibly updates when the alert box is up, but without that the button doesn't visibly disable until after the table clears (which is about 3 or 4 seconds with 1500 rows), it just stays in it's down/"mid-press" state. I don't have a problem with the time the browser is taking to render the table changes, that's just life, but I need the users to see visible feedback so they know the search has started

• Javascript BBcode function not working

  - by Dave

  I have a string I want to convert to divs but it doesn't close the div properly. The example string i am using is this: [quote]Quote by: user1 [quote]Quote by: user2 ads[/quote]Test[/quote]Testing 2. This results in: <div class="quote" style="margin-left:10px;margin-top:10px;"> Quote by: user1 [quote]Quote by: user2 ads </div> Test[/quote]Testing 2. But it will not convert the internal quotes properly. My Javascript function is like this: function bbcode_parser(str) { search = new Array( /\[b\](.*?)\[\/b\]/g, /\[i\](.*?)\[\/i\]/g, /\[quote](.*?)\[\/quote\]/g, /\[\*\]\s?(.*?)\n/g); replace = new Array( "<strong>$1</strong>", "<em>$1</em>", "<div class='quote' style='margin-left:10px;margin-top:10px;'>$1</div>"); for (i = 0; i < search.length; i++) { str = str.replace(search[i], replace[i]); } return str; } I have provided a JSFiddle for you to see it in action: http://jsfiddle.net/gRaFW/2/ Please help :)

• recursive wget with hotlinked requisites

  - by dongle

  I often use wget to mirror very large websites. Sites that contain hotlinked content (be it images, video, css, js) pose a problem, as I seem unable to specify that I would like wget to grab page requisites that are on other hosts, without having the crawl also follow hyperlinks to other hosts. For example, let's look at this page https://dl.dropbox.com/u/11471672/wget-all-the-things.html Let's pretend that this is a large site that I would like to completely mirror, including all page requisites – including those that are hotlinked. wget -e robots=off -r -l inf -pk ^^ gets everything but the hotlinked image wget -e robots=off -r -l inf -pk -H ^^ gets everything, including hotlinked image, but goes wildly out of control, proceeding to download the entire web wget -e robots=off -r -l inf -pk -H --ignore-tags=a ^^ gets the first page, including both hotlinked and local image, does not follow the hyperlink to the site outside of scope, but obviously also does not follow the hyperlink to the next page of the site. I know that there are various other tools and methods of accomplishing this (HTTrack and Heritrix allow for the user to make a distinction between hotlinked content on other hosts vs hyperlinks to other hosts) but I'd like to see if this is possible with wget. Ideally this would not be done in post-processing, as I would like the external content, requests, and headers to be included in the WARC file I'm outputting.

• LINQ Many to Many With In or Contains Clause (and a twist)

  - by Chris

  I have a many to many table structure called PropertyPets. It contains a dual primary key consisting of a PropertyID (from a Property table) and one or more PetIDs (from a Pet table). Next I have a search screen where people can multiple select pets from a jquery multiple select dropdown. Let's say somebody selects Dogs and Cats. Now, I want to be able to return all properties that contain BOTH dogs and cats in the many to many table, PropertyPets. I'm trying to do this with Linq to Sql. I've looked at the Contains clause, but it doesn't seem to work for my requirement: var result = properties.Where(p => search.PetType.Contains(p.PropertyPets)); Here, search.PetType is an int[] array of the Id's for Dog and Cat (which were selected in the multiple select drop down). The problem is first, Contains requires a string not an IEnumerable of type PropertyPet. And second, I need to find the properties that have BOTH dogs and cats and not just simply containing one or the other. Thank you for any pointers.

• DB Strategy for inserting into a high read table (Sql Server)

  - by Tom

  Looking for strategies for a very large table with data maintained for reporting and historical purposes, a very small subset of that data is used in daily operations. Background: We have Visitor and Visits tables which are continuously updated by our consumer facing site. These tables contain information on every visit and visitor, including bots and crawlers, direct traffic that does not result in a conversion, etc. Our back end site allows management of the visitor's (leads) from the front end site. Most of the management occurs on a small subset of our visitors (visitors that become leads). The vast majority of the data in our visitor and visit tables is maintained only for a much smaller subset of user activity (basically reporting type functionality). This is NOT an indexing problem, we have done all we can with indexing and keeping our indexes clean, small, and not fragmented. ps: We do not currently have the budget or expertise for a data warehouse. The problem: We would like the system to be more responsive to our end users when they are querying, for instance, the list of their assigned leads. Currently the query is against a huge data set of mostly irrelevant data. I am pondering a few ideas. One involves new tables and a fairly major re-architecture, I'm not asking for help on that. The other involves creating redundant data, (for instance a Visitor_Archive and a Visitor_Small table) where the larger visitor and visit tables exist for inserts and history/reporting, the smaller visitor1 table would exist for managing leads, sending lead an email, need leads phone number, need my list of leads, etc.. The reason I am reaching out is that I would love opinions on the best way to keep the Visitor_Archive and the Visitor_Small tables in sync... Replication? Can I use replication to replicate only data with a certain column value (FooID = x) Any other strategies?
