If you get blank popup boxes in WordPress, for example when using the visual editor you are unable to add or edit a link in posts, then try the following..
Add your domain (like example.com, no need for the http or the www.) to the whitelist in your firewall or antivirus program that is blocking popups/ads/banners. I use Kaspersky, and to do this, go to Settings, Anti-Banner, then click on Settings and add your domain.
Check your browser addons, some have URL checkers that could be causing a problem. I use FireFox with the Kaspersky URL Advisor Add-on. Try adding your domain to the exclusion list by clicking in FireFox – Tools, Add-ons, click on Options under Kaspersky URL Advisor, then add your domain to the exclusion list.
Close and reload your browser.
This is another very good example of how a problem or setting change in one piece of software can impact on the performance of another piece of software.
The current trend these days seems to be one of giving laptops super glossy screens. Yes, they look great, but spend more then five minutes doing actual work and your eyes begin to ache. The main culprit appears to be the ambient light reflecting off the screen into your eyes.
Through Google searching I found a filter called ViewGuard. Specifically a ViewGuard Anti-Glare Matte Screen Protector.
See the picture below for my before and after results.
The difference is impressive.. my headache disappeared and I find working on the laptop far more enjoyable. However, fitting a filter is no match for having a matte screen in the first place. I could not find a laptop in my price/performance range with a matte screen, so I knew when I ordered it that I would have to find a filter solution or get used to working with a glossy screen. I also found the large filter ( 17.3″ ) hard to fit.. notice the bubbles in the after picture, I’ll have another go at removing them later, however I hardly notice them in use, so I may just leave them for now.
The IVLM2-5/7 is a dual colour VFD display. It has two sets of segments. One BLUE and one ORANGE, arranged in the standard 5 rows x 7 columns format.
Driving the display is as simple as scanning the rows and columns with the desired segment patterns. This interface board I designed takes care of all the tedious display refresh work, freeing up a host microcontroller OR old fashioned logic circuits to do other things.
The display does not flicker to the human eye, the video camera is picking up the refresh.
The details in a nutshell….
Display power requirements:
200mA filament current
up to 70V DC bias voltage ( I am using 30V DC in my example above )
5V supply for logic.
It sounds complicated, but in reality it is very easy! ( Honest! )
Display interface options:
I2C
SPI
LOGIC (no host microcontroller required! )
- several general purpose digital I/O available for use with future software upgrades to onboard controller.
Display features:
On-board microcontroller handles all the scanning and VFD refresh requirements.
Standard character-set stored in microcontroller memory for access via one of the interface options. Special characters and effects selected by external pin or in software.
Display PCB settings:
Address – for SPI/I2C
Bias brightness control, important to trim each individual display
Mode setting jumper
PCB Mounting:
Four holes allow easy mounting to a backplane.
I’ll soon be making a mini wall of these VFD displays. Check back soon!
It’s a nice touch to be able to quickly identify the original post author or site owner comments. I think the easiest way to achieve this is by styling the background.
I picked up this bargain on eBay recently. It’s a Velleman kit ( they make pretty good kits ). I dont normally buy kits, as I can design my circuit, but the price made this worth buying.
Put simply, a favicon is that little logo you see next to the web site title in your browser tab bar and bookmarks list. Think of it as a graphical fingerprint for the site.
A favicon :
makes your site look more professional.
visually tags your site in bookmark lists and browser tab navigation.
Here on this site, I ran into the problem of using images, in this case favicons,with text in link lists. For some reason the wp_list_bookmarks() function in WordPress does not allow link text to be displayed simultaneously with an image. A quick google search showed numerous solutions, and I present here the one I decided to use.
