JavaScript & JQuery

Over that last 50 years many computer languages have evolved. In 1995 JavaScript (originally Mocha) appeared on the scene. It is based on ECMAScript a Standard for scripting languages. Unlike html that works on static parts of the webs design, JavaScript allows us to do dynamic actions including a little animation to improve user interactions on websites. It can be written in the same document we use for our html coding. Java script is used to run dynamic actions after the page has loaded. It is the only scripting language supported by all web browsers that support client-side.

JavaScript became popular despite one or two draw backs. It can be slow to processes or take several lines of coding for one simple action. However, these problems have been  overcome with the development of frame works that created syntactical shortcuts for JavaScript users. About 2006, JavaScript framework know as JQuery got its start and became a library for collection of open source coding.  I like JQuery because I do not have to be a JavaScript expert to used it, and the coding has already been debugged by the code author, and its free.  I likely could get by just looking for JQuery items rather than creating my own javascript coding  from scratch.

Spring Snow

We waited all winter for this month of spring skiing. The time of year when you lose your mittens and trade your ski cap for a baseball cap. Our skis actually glide over the snow on a cushion of water, like they were design to. Skiing is such a delight.

March madness passes in a blur. Icycles It now April, and the thaw is on full force, changing the soundscape around my house. In the morning the icy crust on the snow crunches under my weight, then by afternoon, each step if followed by a swash of slush. I fall asleep to the sound of water drops sliding of the second story roof snow pack and banging on to the metal awning below.

I want to continue to ski in the sunshine, but my path is booby-trapped with by patches glacier ice in the low lands, sandpaper earth on southern exposed trails or collapsing snow depth on low use sections of the trails. Others have traded their skis for running shoes, but they have also left the forest for paved roads.  My first run of the season ended in a mud bath. I slipped on the icy spot on the dirt road right into the thawed earth (ie mud). Break-up is such a painful time.

Blue Bird Day

The Rites Of Spring: bearing witness to the migrants return to the north.

This weekend my husband and I joined the Arctic Audubon group on their annual
field trip to Delta. Our goal was to reach the Clearwater lake and pay homage to Trumpeter swans that had return to the north. If our timing was correct and the birds knew Saturday was our field trip day, we might see several hundreds of these elegant white birds.

The group meet at the barn at the Creamer’s Field Migratory Wildlife Refuge early Saturday morning to carpool to Delta. The Creamer’s Field was a Fairbanks hotspot for seeing the first waterfowl of the season. The refuge staff had prep the field for birds, They had plowed the deep snow into alternating lanes of snow berms and bare earth. The area was also salted with corn to attract birds and draw them away from the only other area of snow free habitat (i.e. the airport). The air was full of goose and swan’s calls. I was surprised to see the parking was busy even at 8 am morning. And the only reason people were using this parking lot was to see the birds!!!

Our small group departed Creamer’s Field and headed south to Delta. We stopped at each vantage point along the highway to look and listen for birds. Someone spotted a Junco but no other migrants.  Birding was a bit slow.  We checked on two known Bald Eagle nest sites including the one across the river from Rita’s Roadhouse.  Eagles were taking up there traditional nest sites.  A good sign so we moved on to Clearwater lake.

Clearwater Lake was active with bird life. There were 3 to 4 thousand Canada Geese on the water, with more coming in as we watched. However, the Trumpeter Swan count was low, only a couple dozen swans. Northern Pintails were also present but estimating the numbers of these smaller birds were difficult because they were quite a distance from us. A pair of Common Merganser and one male golden-eye kept the swans company. Four large gulls, perhaps Herring Gulls were also present. A pair of eagles were patrolling the lake shore.

To find more raptor species we moved on to Saw Mill Creek. Myself, I was hoping for a sighting of Mountain Bluebirds. My husband had not seen one yet in Alaska. Years back, in hopes of building up the Blue Bird population, the Delta boy scout group had placed nest boxes on a large barn . In recent years, sightings of Bluebirds have been low, but I still held hope for seeing one. The Raptor lovers were not disappointed. We had a great show put on by Rough-legged hawks. We saw 5 hawks in the air at the same time. Northern Harriers were also spotted.

It was a beautiful spring day. The sparkling white Delta range was a stunning backdrop to the river and farm fields.  Despite missing the Mountain Bluebird, it still was a prefect blue bird day.

Beastly Letters

Mayanday10Let’s play twenty questions:  What has a tail, beak, chin, leg, arms, shoulders, spines, neck, eye, and hairline, but no blood or brains?
Give up?
The answer is the printed character for a letter.  The official typography terminology for the style and appearance of printed matter includes tail, beck, and so on.  Ever wonder why are such beastly descriptions are used to describe fine art of lettering?  If you recalled that the evolution of the printed word traces its roots to hieroglyphs or pictograms, to things that do have beaks, tails and chins, it makes sense.  However, not all typography terms fall in the body part department.

Serif and swash were two typography terms that I had a tough time picturing.  I thought if I knew their etymology it might help me understand their graphic meaning. The etymology of serif is likely the anglicized Dutch word “schreef”, meaning “line” or “pen stroke”. Serif is the extra flourish on letters that resembles lettering produced by paint brush or quill point. While San serif (now we are tacking on a French word, without, to the old Dutch word) resembles letters created with a chisel. San serif became popular in the 19th century when metal type became more common in print making.

Swash could mean flamboyantly swagger with a sword, or the sound of water splashing.  I am going to assume Zorro definition because it best fits the decorative extension on a letterform. I recall swashes abound in old texts and formal wedding announcements. The capital letter at the begin of a sentences has an extension to the left or the last letter on the line has an extent to the right. I have read that swashes were used in former times to help fit the text to the line, instead of spaces of varying widths.

First blog post

What better way to start my first post for Marks In The Sky then to announce the arrival of first geese to Fairbanks. Canada Geese have landed at Creamer’s Field.  I am going to ignore the snow flakes that fell this morning and focus on the winged harbingers of spring. animals-2030018_960_720 Snow Buntings, another early migrant has been sighted in Interior Alaska. I saw a small flock along the Chena Hot Springs Road. Golden Eagles and Red-tailed Hawks are also on the move, according to the hawk watchers at Gunsight Mountain.  Keep your eyes peeled for more marks of spring in the sky.
