Howling In The Night

Blog, Recent Posts, Software
October ends on Halloween night. Spooky, cold windy nights relinquished to thoughts of witches, ghosts, and monsters. There’s nothing to fear, or so we are told. Are the ancient incantations of old simply a cloudy evolution on our current computer coding? The programs and configurations that run our modern world misunderstood by many who rely on this magic everyday. The disembodied voices from beyond time and space now traveling the world on multiple high speed networks. Of course we have new monsters to loath superimposed against vague shadows cast by massive assemblies of robots spawned by artificial intelligence run amuck. Oooh Scary stuff! Presumably very little has truly changed over the years beyond the current presentation. Writing code has morphed into the new wizardry which of...

Dark Roasted Conspiracy

Software, Blog, Linux, Recent Posts
As the daylight hours grow shorter and darkness becomes the prevailing theme, the temperatures drop and the winds blow cold. It feels like the night never ends. The leaves are falling and swirling down the road. Without the sun’s energy and warmth, a good fire and a hot cup of dark roast coffee help take away the ever-present Autumn chill. Coffee is an ever-persistent habit for me. I like good coffee, and it keeps me going like high octane fuel. No cream, no sugar, not for me.I like coffee, just black coffee. The darker the roast, the better I like it. It’s a basic thing. You can make it more complicated than it has to be, or you can learn to appreciate it’s simplicity. I don’t care what other people put in their coffee, everyone is different. I only worry about my own. Just don’t mess w...

Learn To Manipulate Data Frames Using The “mtcars” Dataset Below is an introduction to programming with r, all code in this exercise is only using base r and no other libraries are needed. Task 1: Create a new column to find Displacement per Cylinder  Create a new variable (DisplacementPerCylinder), to calculate the total displacement per cylinder in cubic inches for each vehicle from the mtcars dataset. # "str" allows you to display the internal structure of an R object str(mtcars) ## 'data.frame': 32 obs. of 11 variables: ## $ mpg : num 21 21 22.8 21.4 18.7 18.1 14.3 24.4 22.8 19.2 ... ## $ cyl : num 6 6 4 6 8 6 8 4 4 6 ... ## $ disp: num 160 160 108 258 360 ... ## $ hp : num 110 110 93 110 175 105 245 62 95 123 ... ## $ drat: num 3.9 3.9 3.85 3.08 3...

Weather alerts, weather Alerts, notifications everywhere. The iPhone notifications from multiple weather apps are handy, and when you hear the notification alerts from other people’s phones going off around you, you’re going to look at your screen. Something is going on, or soon will be. In the old days, we listened to our radios for weather forecasts, often the local television station weather broadcast. Later on, the soothing sounds of the Weather Channel’s greatest hits played while our local forecast rolled across the screen in-between weather people pointing to a green screen and looking off-camera to create a less confusing presentation illusion. It all worked very nicely. Now we can view the weather in our computer browsers or on a phone app.You can easily view the weather in...
