The predominant “web server software” used for WordPress sites are Apache and nginx. [1. tech discussion: Apache launches a new thread (a “program”) in server memory for every incoming page and object requested by your site visitors. This can rapidly clog the server’s memory as the number of requests per second increases. nginx initially launches a number of threads and then dispatches page/object requests to them for service—properly configured it doesn’t bloat up and fill memory.] Generally on smaller servers nginx will be more efficient because it doesn’t gobble memory like Apache does. The question of which web server software to use hinges primarily on the CPU power and memory resources that are required on the server side to make your site run properly. [Read more…]

Get More Screen Real Estate by Using a USB Display Adapter
I work on a Macbook Pro with a 15-inch screen most of the time (when I’m not on an iPad and mobile). Carting around this portable window on the online world has been easy and nice over the years, but it doesn’t give me enough space to “spread out” my working materials as I would on a desk or table.
My (2008 aluminum) Macbook Pro directly supports (only) one external “DVI” monitor, which extends my workspace by adding a single 24-inch window that I can drag documents onto. But frequently I need more. [Read more…]
US Postal Service “Real Mail Notification” Comes Thru!
Woohoo! The US Postal Service [USPS] comes thru! They’re in the 21st century now!
I work from a home office and I’m one of millions of people in the US who have a post office box [POB or PO Box] for delivery of business mail, rather than having it all come to my house. One of the problems with having a “PO Box” is that I have to go to the post office to pick up the mail, and things don’t arrive every day. Usually there’s mail only one or two days a week.

Summer of Yosemite 2012
It has been my plan to make several trips into the Yosemite wilderness this summer in order to visit some places I’ve never seen before. Most tourists have seen Yosemite “Valley” and many have seen Tuolumne Meadows. Access to the wilderness areas is controlled by a “permitting” process that limits the number of people who may enter on a wilderness trailhead each day. There are a couple dozen trailheads, and they have quotas of one to two dozen camper-hikers per day per trailhead. Once you’re into the wilderness area, you can pretty much go where you desire, as long as you have the energy and the food. [Read more…]
SOTA—Summits On The Air
Since the age of 6, when I visited Estes Park, Colorado, whenever I see any geographical feature more than say 100 meters above me, I climb it. (Provided it’s not a technical climb.) If I can get there without hanging by my fingertips, I go.
Summits On The Air [SOTA] is an organization that operates mostly in Europe and the US, which encourages amateur radio operation from mountain peaks. In many areas these are really just large hills, but here the western mountains of the US, we have many hundreds of peaks that are truly mountains and not just high spots. [Read more…]
