  • large databases in sqlite - file size considerations?

    - by Gj
    I'm using a sqlite db which is very convenient and seems to meet all of my needs at this point. Currently my db size is <50MB, but I now need to add a new table which will store large text blobs, which will cause the db to reach up to 5GB within the next year. Would sqlite be able to deal with a 5GB db size? Any caveats to that, compared with say mysql?

  • Count of products NOT sold...per store, per day over the past month

    - by user1893510
    I'm struggling with an interview question. 3 dimension tables (Product, Store and Date) and 1 fact table (Sales). The question asks for a T-SQL solution that will return the count of products not sold, per store, per day over the past month. At this point, my answer is futile but I've spent significant time trying to back into a solution, to no avail, and would like to close the loop. Any guidance is greatly appreciated.

  • Data Generation Plan Missing from VS2010 Pro

    - by chobo2
    Hi I was following this tutorial http://nepomucenobr.com.br/blog/post/Generating-e2809cdummy-datae2809d-with-Visual-Studio.aspx and I got to the point where I am should add a data generation plan file. Yet when I click on the folder there is not data generation plan file. I don't know why. Do I have to install it separately or what? Or is it because I am using 2005 express?

  • Avoiding explicit recursion in Haskell

    - by Travis Brown
    The following simple function applies a given monadic function iteratively until it hits a Nothing, at which point it returns the last non-Nothing value. It does what I need, and I understand how it works. lastJustM :: (Monad m) => (a -> m (Maybe a)) -> a -> m a lastJustM g x = g x >>= maybe (return x) (lastJustM g) As part of my self-education in Haskell I'm trying to avoid explicit recursion (or at least understand how to) whenever I can. It seems like there should be a simple non-explicitly recursive solution in this case, but I'm having trouble figuring it out. I don't want something like a monadic version of takeWhile, since it could be expensive to collect all the pre-Nothing values, and I don't care about them anyway. I checked Hoogle for the signature and nothing shows up. The m (Maybe a) bit makes me think a monad transformer might be useful here, but I don't really have the intuitions I'd need to come up with the details (yet). It's probably either embarrassingly easy to do this or embarrassingly easy to see why it can't or shouldn't be done, but this wouldn't be the first time I've used self-embarrassment as a pedagogical strategy. Background: Here's a simplified working example for context: suppose we're interested in random walks in the unit square, but we only care about points of exit. We have the following step function: randomStep :: (Floating a, Ord a, Random a) => a -> (a, a) -> State StdGen (Maybe (a, a)) randomStep s (x, y) = do (a, gen') <- randomR (0, 2 * pi) <$> get put gen' let (x', y') = (x + s * cos a, y + s * sin a) if x' < 0 || x' > 1 || y' < 0 || y' > 1 then return Nothing else return $ Just (x', y') Something like evalState (lastJustM (randomStep 0.01) (0.5, 0.5)) <$> newStdGen will give us a new data point.

  • How long can rails keep Ajax open

    - by Alexey
    My application is suppose to constantly update the page without any user interaction. The criteria is that the page just has to be there, as an extra window on the monitor so the user can see the information get updated real time. I'm using the Ajax in jQuery with Rails, and my question is - how long will the .erb page keep Ajax open? Will there be a point where I have to refresh the page or re-initialize? Or will that won't be a problem at all?

  • Mapping One-to-One subclass in Fluent NHibernate

    - by Mike C.
    I have the following database structure: Event table Id - Guid (PK) Name - NVarChar Description - NVarChar SpecialEvent table Id - Guid (PK) StartDate - DateTime EndDate - DateTime I have an abstract Event class, and a SpecialEvent class that inherits from it. Eventually I will have a RecurringEvent class which will inherit from the Event class also. I'd like to map the SpecialEvent class while preserving a one-to-one relationship mapped with the Ids, if possible. Can anybody point me in the correct direction? Thanks!

  • Intents? How to register to be alerted for incoming emails?

    - by Justin
    Extreme Android developer newbie here...well, new to Android development, not development in general. I want to write an application that gets notified when emails come into the device, and takes various actions based on data in the email (subject, sender, to, etc). I think what I have to do is create a BroadcastReceiver with an IntentFilter. The problem I'm having is figuring out what Intent(s) I need to "listen" for. Can anyone point me in the right direction? Thanks.

  • ZF-Autoloader not working in UnitTests on Ubuntu

    - by Sam
    i got a problem regarding Unit-testing a Zend-Framework application under Ubuntu 12.04. The project-structure is a default zend application whereas the models are defined as the following ./application ./models ./DbTable ./ProjectStatus.php (Application_Model_DbTable_ProjectStatus) ./Mappers ./ProjectStatus.php (Application_Model_Mapper_ProjectStatus) ./ProjectStatus.php (Application_Model_ProjectStatus) The Problem here is with the Zend-specific autoloading. The naming convention here appears that the folder Mappers loads all classes with _Mapper but not _Mappers. This is some internal Zend behavior which is fine so far. On my windows machine the phpunit runs without any Problems, trying to initiate all those classes. On my Ubuntu machine however with jenkins running on it, phpunit fails to find the appropriate classes giving me the following error Fatal error: Class 'Application_Model_Mapper_ProjectStatus' not found in /var/lib/jenkins/jobs/PAM/workspace/tests/application/models/Mapper/ProjectStatusTest.php on line 39 The error appears to really be that the Zend-Autoloader doesn't load from the ubuntu machine, but i can't figure out how or why this works. The question remains of why this is. I think i've double checked every point of contact with the zend autoloading stuff, but i just can't figure this out. I'll paste the - from my point of view relevant snippets - and hope someone of you has any insight to this. Jenkins Snippet for PHPUnit <target name="phpunit" description="Run unit tests with PHPUnit"> <exec executable="phpunit" failonerror="true"> <arg line="--configuration '${basedir}/tests/phpunit.xml' --coverage-clover '${basedir}/build/logs/clover.xml' --coverage-html '${basedir}/build/coverage/.' --log-junit '${basedir}/build/logs/junit.xml'" /> </exec> </target> ./tests/phpunit.xml <phpunit bootstrap="./bootstrap.php"> ... this shouldn't be of relevance ... </phpunit> ./tests/bootstrap.php <?php // Define path to application directory defined('APPLICATION_PATH') || define('APPLICATION_PATH', realpath(dirname(__FILE__) .

'/../library'), get_include_path(), ))); require_once 'Zend/Loader/Autoloader.php'; Zend_Loader_Autoloader::getInstance(); Any help will be appreciated.

  • Why JEE is widely used in complicated projects?

    - by cane
    Hi. Yesterday me and my friend we've had nice conversation about IT and he asked me WHY JEE is so widely used when it comes to build complicated IT systems? From my point of view advantages are easily visible, but he is IT manager with a lot of Micro$oft experience (and little Java exp.), so I would like to hear your voice. And I'll give him a link of course. I don't want new .NET - JAVA war - just - why JEE :) Thanks, orsonek

  • php download file slows

    - by hobbywebsite
    OK first off thanks for your time I wish I could give more than one point for this question. Problem: I have some music files on my site (.mp3) and I am using a php file to increment a database to count the number of downloads and to point to the file to download. For some reason this method starts at 350kb/s then slowly drops to 5kb/s which then the file says it will take 11hrs to complete. BUT if I go directly to the .mp3 file my browser brings up a player and then I can right click and "save as" which works fine complete download in 3mins. (Yes both during the same time for those that are thinking it's my connection or ISP and its not my server either.) So the only thing that I've been playing around with recently is the php.ini and the .htcaccess files. So without further ado, the php file, php.ini, and the .htcaccess: download.php <?php include("config.php"); include("opendb.php"); $filename = 'song_name'; $filedl = $filename . '.mp3'; $query = "UPDATE songs SET song_download=song_download+1 WHER song_linkname='$filename'"; mysql_query($query); header('Content-Disposition: attachment; filename='.basename($filedl)); header('Content-type: audio/mp3'); header('Content-Length: ' . filesize($filedl)); readfile('/music/' . $filename . '/' . $filedl); include("closedb.php"); ?> php.ini register_globals = off allow_url_fopen = off expose_php = Off max_input_time = 60 variables_order = "EGPCS" extension_dir = ./ upload_tmp_dir = /tmp precision = 12 SMTP = relay-hosting.secureserver.net url_rewriter.tags = "a=href,area=href,frame=src,input=src,form=,fieldset=" ; Defines the default timezone used by the date functions date.timezone = "America/Los_Angeles" .htaccess Options +FollowSymLinks RewriteEngine on RewriteCond %{HTTP_HOST} !^(www.MindCollar.com)?$ [NC] RewriteRule (.*) http://www.MindCollar.com/$1 [R=301,L] <IfModule mod_rewrite.c> RewriteEngine On ErrorDocument 404 /errors/404.php ErrorDocument 403 /errors/403.php ErrorDocument 500 /errors/500.php </IfModule> Options -Indexes Options +FollowSymlinks <Files .htaccess> deny from all </Files> thanks for you time

  • create a git symbolic ref in remote repository

    - by Banengusk
    In my remote bare repository the HEAD is pointing to "refs/heads/master" and I want it to point to "refs/heads/other". I am not able to go to remote repository directory and run git symbolic-ref. Is there any git command to achieve it? Or any other way? If there is no way, does Github allow to change the HEAD? Thanks in advance.

  • Is it possible to generate a XSL-FO template from a PDF?

    - by Vihung
    Given a PDF document, is it possible to generate a XSL-FO (FOP) template? Obviously, this would be a one-time thing - the generated template would just be a starting point for creating a proper template that pulls in the appropriate data. For me, the ideal tool for doing so would be a Java-based one and should be executable from the command line or through an ANT task. Failing that, it would be something that runs on Linux and MacOS X.

  • Java's equivalent to bisect in python

    - by systemsfault
    Hello all, Is there a java equivalent to python's bisect library? With python's bisect you can do array bisection with directions. For instance bisect.bisect_left does: Locate the proper insertion point for item in list to maintain sorted order. The parameters lo and hi may be used to specify a subset of the list which should be considered; by default the entire list is used.
