Tokina AT-X 100MM F/2.8 PRO FX MACRO

The AT-X 100 PRO D is an excellent 100mm F/2.8 macro lens capable of life-sized (1:1) reproduction at 11.8 in. (30 cm). The lens’ multi-coating have been re-engineered to match the highly reflective silicon based CCD and CMOS sensors in today’s digital SLR cameras. This lens gives the best of both worlds because optics still give full coverage and excellent sharpness with full frame sensors as well as 35mm film. The AT-X 100 PRO D also has a very convenient focus limiter switch that can lock the focus out of the closes focus making it focus faster when used as a moderate telephoto lens that is excellent portraits as well. Other features of the AT-X 100 PRO D are: Tokina One Touch Focus Clutch Mechanism for fast easy switching between manual and Auto focus. 55mm non-rotating filter thread for use with macro ring flashes and special effects filters. The AT-X 100 PRO D also comes with a deep bayonet mounted lens hood. Autofocus with this lens is not supported with Nikon DSLRs that do not have a focus motor in the camera body.


Things I like on Netflix

Psychokinesis (2018)
An ordinary guy suddenly finds he has superpowers he can use to help his spirited daughter and the people around them, but he also runs into trouble in the process.
Erased (2017) After finding his mom killed, Satoru’s time-traveling ability takes him back 18 years for a chance to prevent her death and those of three classmates.
Ash vs Evil Dead (2015) The series is set approximately 30 years after the first three Evil Dead films, and serves as a sequel to that trilogy. Ash Williams works at the “Value Stop” as a simple stock boy. Also working at the store is his friend Pablo and the object of Pablo’s affections, Kelly. Ash has seemingly done very little with his life since returning from 1300 AD at the end of Army of Darkness, and the beginning of the series sees him living in a trailer and drinking alone in bars. However, Ash must soon renounce his routine existence and become a hero once more by taking up arms and facing the titular Evil Dead. Pablo and Kelly decide to join him on his quest to save humanity.

How to set up Docker on Windows to use VMWare (instead of VirtualBox or Hyper-V).

  1. Get Docker:
  2. Get Docker Machine:
  3. Get vmware driver for docker machine:
  4. Extract docker zip somewhere (e.g. C:\apps)
  5. Copy docker-machine-Windows-x86_64.exe into the new docker folder and rename it to docker-machine.exe.
  6. Copy docker-machine-driver-vmwareworkstation.exe into the new docker folder.
  7. Run a shell (CMD or PowerShell) and add the docker folder to your path
  8. Run “docker-machine create –driver vmwareworkstation default”. This will download the boot2docker.iso and create a new docker machine named “default” in C:\Users\{username}\docker\machine\machines\default.
  9. Either:
      1. Run “docker-machine env default >default.cmd” to create a batch file that sets up the environment.
      2. Run “call default.cmd” to set the environment. This makes “default” the default machine for docker commands.
    • Or:

    • eval “$(./docker-machine env default)” from a UNIX-like shell such as cygwin’s mintty
  10. Now use docker. For example “docker version”.

Camera Lens Codes

I did not create this. This info was taken directly from this page at stackexchange.
I reproduced it here with some simplification because you can’t trust The Internet. Here today, gone tomorrow. Thank you to the many people who contributed this info to the community.

Descriptions by Lens Make



  • XYZmm: Focal length
  • f/x.y: Maximum aperture (or f/a.b-c.d for variable aperture zooms)

Focus/Mount Type

  • EF: Electro-Focus
  • EF-S: Electro-Focus, Short back-focus
  • EF-M: Electro-Focus, Mirrorless (EOS M)
  • TS: Tilt-Shift (manual focus)
  • TS-E: Tilt-Shift, Electronic aperture control
  • MP-E: Macro-Photography, Electronic aperture control (manual focus)
  • PE: Prohibitively Expensive


  • IS: Image Stabilization
  • USM: Auto Focus Type: Ultrasonic Motor
  • STM: Auto Focus Type: Stepping Motor
  • (Roman numeral) N: Version of lens (II = v2, III = v3, etc.) (The word Mark is not present in lens names, only in camera body names)
  • DO: Diffractive Optics
  • L: Luxury series
  • Macro: close focusing, but not necessarily 1:1 magnification
  • Softfocus ability to use soft focusing for smooth dreamy look
  • PF Power Focus (PF isn’t included in the official lens name published by Canon for lenses that include this feature)



  • XYZmm: Focal length
  • Fx.y: Maximum aperture

Lens Mount

  • X-mount: The modern, fully-electronic lens mount used in Fujifilm’s X-series cameras.
  • Fujinon: Fujifilm’s blanket term for its lenses which use this mount.

Lens Construction

  • XC: “Compact and casual” lower-cost lenses, generally with plastic barrels and a metal bayonet mount
  • XF: Higher-end lenses with metal body construction,
    usually faster maximum aperture, and often exotic lens elements (these
    are not usually called out by other designators in the lens name).
  • “Red Badge” or “Red Label”: XF lenses with the label in red; reserved for higher-end zoom lenses.


  • APD: Apodization filter for improved bokeh
  • LM: Linear Motor (faster than the standard motor)
  • Macro: Not necessarily “true” 1:1 macro; also found on lenses with 1:2 (0.5

French Press Coffee

I have the Bodum Chambord 34oz french press. Bodum says “all of our coffee and tea makers are measured in European cup sizes: 1 Cup = about 4oz.” If you fill the press up to the top of the upper metal band it’s about 32oz so the math works. My favorite mug is about 12oz so that’s closer to 3 cups for me.

My Perfect Brew

  • Water: 200 degrees (my electric kettle has a setting for this)
  • Coffee: 5 tablespoons medium roast (4 ish for dark)
  • Brew Time: 4.5 minutes
