A couple of years ago I created a very simple QC-chart to keep track if instrument performance over periods of time. The chart fetches the usual data from user input and calculates average, upper and lower control and warning limits, and plots these data into an Individuals chart and a Moving average chart.

Once you have established the acceptable performance of your instrument/method, this makes it very easy to see if your method is performing poorly.

The baseline performance is usually established by collecting data over an extended time period, say one month, using some form of stable reference testing material. In the case of chemical analysis this can be a certified reference material (CRM) consisting of for example metal ions of a known concentration in a stable sample matrix.

Therefore I was quite excited to find a plugin called Simple:Press forum, which is a forum with features and functions that is much closer to what you expect to find i a modern forum:

• ‘Pretty/SEO’ Friendly Permalinks. And the good news - should also be able to display links with the old url structure.
• Private Messaging - the second most regular request.
• Powerful User Group and Permission structure. Fine control over who can see and do what.
• New ‘QuickLinks’ dropdown on the Search Bar displaying recent and unread posts
• Bulk Moderate Posts needing approval and read new posts in one place
• Login Form bought into current page view
• Mass Deletion tool for the removal of old topics
• Many ‘Custom’ options: Up to three custom icons in login bar; set custom icons for all Groups and Forums; Use a graphic in place of page title; Create a special ‘editor’ message
• Redirect RSS Feeds to external services (i.e., FeedBurner)
• ‘Pluggable’ page rendering code allowing replacement functions and custom code routines
• TinyMCE V3 with much improved text handling and formatting
• Optional Image File Uploading (only using TinyMCE editor)
• Improved Notification, Messaging and form validations
• EMail Overrides and create text of New User Email
• Democracy Polls plugin support
• Images as Thumbnails that expand

This one I struggled with and in the end it came out like something of a abomination of a function, but at least it gets the job done. It uses the WP_AUTHENTICATE hook to call the function where a simple login check is done, and if successful, the timestamp is writted to the wp_users table.

You can either insert a new field called user_lastlogin (or what you prefer) in wp_users like I did, or you can make a new table to store the login log.

The code follows below. Happy logging!

My ambition one year ago was to  make a welcome side income from web publishing/advertizing and during this year I’ve tried affiliate marketing, domain trading and web site publishing. I’ve learnt that success may come unexpectely, in our case from a site about pregnancy and maternity (Bli Mamma gravid), an idea that actually my wife came up with. From a quiet start this site now has about 2,000 page views per day and generates from $3 to $40 per day depending on current advertizing campaigns. At the moment we use a combo of AdSense and Tailsweep ads, something that has proven successful.

My other project, called  Hyrprylen.se, which is basically a classified ad site for rentals of gadges and property, is yet to be launched. I coded this site from scratch, thus it is a bit rough. But it might have a potential, especially as we will port it to other languages as well. The platform can also be easily be used for realty, traditional classifieds and vacation home rentals. We’ll see about that one.

This is of course every web publishers wet dream; another tool to visualize your AdSense earnings, and now easier than ever. Ever since AdSense notifier stopped working a couple of months ago I’ve been dying to find a new tool/toy and now I’ve found it.

Installing it takes about 30 seconds (seriously) and testing it another 30. It works perfecly and is very very handy.

The design uses two transparent gif masks (easily created in for example GIMP) and  a short, organized CSS:

dl {
  width: 240px;
  margin: 0 0 20px 20px;
  background: #999 url(box_bottom.gif) »
  no-repeat bottom left;
  } dt {
  margin: 0;
  padding: 10px;
  background: #999 url(box_top.gif) »
  no-repeat top left;
  }
