Trench Coat



Looking around for a men's trench coat that is : (1) navy or cadet-blue; (2) ankle-length; (3) preferably 100% wool; (4) double-breasted.

  • Command Uniforms of Sacramento was listed as a distributor of Newport Harbor, but no longer exists. :(

CSUS CSC 130 Second Midterm Exam Grades

The second midterm grades from my class this semester are in; it was another bloodbath:

Section One Section Two
90+
1
2
80-89 3 5
70-79 7 4
60-69 7 7
50-59 6 4
49- 6 4
Average 61.90 65.85
Standard Deviation 16.29 20.11

Maximum possible points were 100. Out of 56 test takers: 3 earned an A (5%); 8 earned a B (14%); 11 earned a C (20%); 14 earned a D (25%); and 20 earned an F (36%). The test counts for 15% of the final grade.

I earned a 96 on this one. o_O;;;

One might compare this with the first midterm exam and find three signs of improvement: (1) failures dropped from 58% to 36%; (2) passing scores (C and up) increased from 22% to 39%; and (3) above average scores (B and up) increased from 11% to 19%.

On the negative side, 61% (3 in 5) earned a D or worse (compared to 79% from the first midterm). Three in five students have been left behind and are unlikely to catch up and "get" this material. :(

The increasing standard deviations between the two tests confirm a greater spread away from the average.

This comment on SacRate.com, however, may provide hope for even these students: "Has a huge curve. I had 47% before the final, got 66/100 and ended up with a B+ after the curve."

Food for thought. :X

Implmenting LZW Compression Algorithm

Today I am implementing the LZW data compression algorithm as a toy project.

LZW stands for Lempel, Ziv, and Welch, its creators. It was the first widely used universal data compression method on computers.

Its popularity led it to be included in many file formats people use every day: GIF and TIFF images, PDF files, and files sent to your printer.

Early Days

Fell into a transcript of an interview with Gerald D. Cohen, founder of Information Builders, Incorporated in 1975, whose first product was FOCUS, one of the leading mainframe databases of that era, from about 1970 to 1980. The whole thing is a fascinating insider's look. The techie part begins around the end of page 13 and continues through RAMIS, then FOCUS.

Originally curious what FOCUS stood for. In the interview above, Mr. Cohen remarks, "We labeled this program FOCUS. I guess it stood for online computer users, but we needed was an acronym that was easy to remember. So we gave it a computer type name, and FOCUS was our term for this non-procedural language."

Meltpools

This fall it is cozy to light a candle while coding and manage the wax to create the largest meltpool.

Learning as I go along. Any tips from the reader base? I am currently melting a 4 x 6" Pier 1 ginger peach.

Some tips from a former Yankee Candle manager.

What I Have Learned About Cooking Duck

  1. Duck fat. Duck fat. Duck fat. Duck fat.
  2. It is hard to go wrong with roast duck.
  3. Trussing.
  4. Stuffed with one or two peeled potato chunks to absorb any off-taste.
  5. How to cut off the head, neck, and feet.
  6. Clipped the wings.
  7. Salt, pepper, and paprika rub.
  8. Pour water into the roasting pan so oven does not get splattered.
  9. About two hours at 190 C (375 F)
  10. Poke holes into the duck to drain the fat layer.
  11. Use a roasting rack; do not want the duck absorbing all the drained fat.
  12. Carving duck does not produce a lot of meat; a bit on the legs, the wings, and breast.
Overall, a lot of praise. Seemed to come out OK.
