  • Lightweight CMS in PHP

    - by David
    Hi, I am building a site which will require some very limited content management for a client. There are only a few areas of the site which will require the client to be able to update the content themselves. Would it be better to create a very simple custom admin page for the client to log in and say add a news story etc or would it be best using a fully fledged CMS like Drupal etc which seems overkill to me.

  • How to invalidate / refresh a domain instance association?

    - by Kimble
    There is a bug in Grails preventing me from using removeFrom* when the node I'm trying to remove is extending the collection type. Removing the node directly from the association won't update the second level cache. A hasMany B Is there any way to manually invalidate or force a reload on an association cache? Invoking refresh() on the many side didn't do the trick.

  • Modifying wordpress plugin markup

    - by D L
    Is there a 'good working practise' way to modify the markup that a wordpress plugin produces without editing the plugin's core files. The problem i foresee is that when you update the plugin, the markup that you would have modified overwritten. I know in drupal there are template overrides, but i don't know enough about wordpress to do a similar practise. Any help?

  • How to change SRID of geometry column?

    - by Z77
    I have table where the one of columns is geometry column the_geom for polygons with SRID. I added new column in the same table with exactly the same geometry data as in the_geom. This another column has name the_geom4258 because I want here to set up another SRID=4258. So what is the procedure to set up another SRID geometry to be changed (in another coord.system)? Is just enough to apply following query: UPDATE table SET the_geom4258=ST_SetSRID(the_geom4258,4258);

  • jquery dialog form with dynamic variables

    - by Patrick
    Hello, Currently I have an html form - which I call with jquery dialog - to insert new records into a table. But I also would like to update existing records with the same form - using jquery dialog. I'm not sure within the dialog how I access these data values - or pass them in as arguments - and hook them up with the form elements...? Anyone has done this before and knows an agile technique to do this? kind regards, Patrick

  • Mercurial: Diff current source vs source at point in time

    - by Marcus
    I know how to view all changes in a changeset.. But let's say you update your source, you do a pull and you get 3 new changesets. How can you compare the current state of the remote repository (with the 3 changesets checked in) vs. the current source (on your local machine)? I'd like to do this using the visual diff tool which I currently have configured (Examdiff or Kdiff3).

  • Postgresql count+sort performance

    - by invictus
    I have built a small inventory system using postgresql and psycopg2. Everything works great, except, when I want to create aggregated summaries/reports of the content, I get really bad performance due to count()'ing and sorting. The DB schema is as follows: CREATE TABLE hosts ( id SERIAL PRIMARY KEY, name VARCHAR(255) ); CREATE TABLE items ( id SERIAL PRIMARY KEY, description TEXT ); CREATE TABLE host_item ( id SERIAL PRIMARY KEY, host INTEGER REFERENCES hosts(id) ON DELETE CASCADE ON UPDATE CASCADE, item INTEGER REFERENCES items(id) ON DELETE CASCADE ON UPDATE CASCADE ); There are some other fields as well, but those are not relevant. I want to extract 2 different reports: - List of all hosts with the number of items per, ordered from highest to lowest count - List of all items with the number of hosts per, ordered from highest to lowest count I have used 2 queries for the purpose: Items with host count: SELECT i.id, i.description, COUNT(hi.id) AS count FROM items AS i LEFT JOIN host_item AS hi ON (i.id=hi.item) GROUP BY i.id ORDER BY count DESC LIMIT 10; Hosts with item count: SELECT h.id, h.name, COUNT(hi.id) AS count FROM hosts AS h LEFT JOIN host_item AS hi ON (h.id=hi.host) GROUP BY h.id ORDER BY count DESC LIMIT 10; Problem is: the queries runs for 5-6 seconds before returning any data. As this is a web based application, 6 seconds are just not acceptable. The database is heavily populated with approximately 50k hosts, 1000 items and 400 000 host/items relations, and will likely increase significantly when (or perhaps if) the application will be used. After playing around, I found that by removing the "ORDER BY count DESC" part, both queries would execute instantly without any delay whatsoever (less than 20ms to finish the queries). Is there any way I can optimize these queries so that I can get the result sorted without the delay? I was trying different indexes, but seeing as the count is computed it is possible to utilize an index for this. I have read that count()'ing in postgresql is slow, but its the sorting that are causing me problems... My current workaround is to run the queries above as an hourly job, putting the result into a new table with an index on the count column for quick lookup. I use Postgresql 9.2.

  • Send data from Service to Widget on Android.

    - by Jose Vega
    I am writing a widget on Android 1.6 that shows the minutes that a person has used on the current month. The way I have it setup is by having a service that listens to the state of the phone and when the phone is picked up, it starts the timer and when the person hangs up, ends a timer. I would like to send this variable(long duration) over to my appWidgetProvider so I could update the edit text on it.
