Recipe for charro-beans (blend americanized version)

September 5th, 2013 by Boanerges Aleman-Meza

Recipe for cooking charro beans, aka, frijoles charros or frijoles rancheros, somewhat blend (americanized), adapted from existing recipe for frijoles charros.


  • 2 lb. beans (normally I use pinto beans)
  • 1/2 lb. bacon
  • 1/2 lb. ham
  • 4 tomatoes + 4 green tomatoes (or their equivalent to the 4 red tomatoes)
  • 3 garlic cloves
  • 1 tbsp salt
  • 2 onions
  • 1 chicken boullion (sounds like a bully but it is not)
  • cilantro (normally I use 1/3 of the chunk, or about 20 stems)
  • Pork skins (one bag of normal size of snack would do)


  1. Clean the beans to avoid stones (you’ll hate a stone, your dentist may like it)
  2. Clean all the veggies
  3. Add lots of water into a pressure pot, add the beans, 1 tbsp salt, 1 garlic clove, 1 onion, then when boiling, adjust flame to avoid exploding the pressure pot, and cook for 35 minutes
  4. Fry the tomatoes and green tomatoes, and the remaining garlic cloves (cut them along the long side in 2 or 3 parts), then use a blender to blend them together with the cilantro and the chicken bouillon
  5. Chop the onion in small parts (approximately the size of squares of 4 millimeters by 4 millimeters)
  6. Fry the bacon until it starts to get golden color, add the onion and fry until the onion is transparent, add the ham and cook for 5 minutes at medium flame or so
    • The original recipe would include chorizo here but some people think it is too strong flavor
  7. When the pressure pot is done with the beans, trash the onion and the garlic clove
  8. Add the stuff you blended into the pressure pot
  9. Add the stuff you fried (bacon, onion, ham) into the pressure pot
  10. Add the pork skins into the pressure pot
  11. Wait until it starts boiling (with no lid) and then cook it for 5 minutes

Mexican beef caldo recipe (soup of beef and veggies)

September 4th, 2013 by Boanerges Aleman-Meza

Recipe to make beef caldo (caldo de res), adapted from an existing caldo de res recipe.


  • 1 tbsp salt
  • 1 clove of garlic
  • 1 onion
  • 3 lbs. beef shanks center cut bone-in
    • I never find it in Kroger, always found it at HEB
    • Alternative: Short Loin with bone
  • 1 lb. butter gold potatoes (or is it honey gold?)
    • I normally use 3 lb. bag because it is a better deal buying the bag
    • I cook them as indicated in the procedure, but when done, I separate them in a different container to avoid having a plate that has too many potatoes in it
  • 1 lb. carrots
    • If you’re rich or want to save time, buy the baby-size carrots
  • 3 corn in the cob
  • cilantro (normally I use 1/3 of the cilantro, or about 20 stems)
  • 5 squash (a.k.a., calabacitas)


  1. Clean all vegies
  2. Use a pressure pot to cook the beef, together with lots of water, the onion, one clove of garlic, and 1 tbsp salt.
    • When boiling, change the flame accordingly so that the pressure pot does not explode and cook for 30 minutes
  3. Depending on the size of the pressure pot, remove (or not) the beef
  4. Trash the onion and the garlic
  5. Peal the potatoes and cut them in half, cut each squash in four parts, cut the carrots in spoon-size chunks
  6. Add everything else into the pressure pot
  7. When boiling, adjust the flame and cook for 1 minute
  8. All done!

Genetics – the basics just before the advanced stuff

August 28th, 2013 by Boanerges Aleman-Meza

Here are a few of my notes about genetics.

Mendelism: Mendel is second on my list of top scientists, just right after Darwin.


  • Gametes: they usually have only one copy of each chromosome (such as sex cells)
  • Zygote: single cell from female gametes and male gametes. “I’ve been using internet before you were a zygote” said Dave Winer, I think.
  • Monohybrid cross: a single trait is studied
  • Dihybrid cross: two traits are studied.
  • Haploid eukaryotic cells have one copy of each chromosome.
  • Diploid eukaryotic cells have two copies of each chromosome.

Worth remembering:

  • In substrate pathways, double mutant shows the upstream gene
  • In signaling pathways, double mutant shows the downstream gene
    • if A suppresses B and A is loss-of-function, then there will be too much B
  • mitosis: duplication into sister chromatids, everything is lined-up in the middle.
  • meiosis I: we have 2 cells, separate homologs, homologs are lined up
  • meiosis II sister chromatids separate
  • recombination: if 100% of tetrads have a crossover, the % of number of progeny showing recombinant types is 50

Where to eat when visiting Houston?

August 21st, 2013 by Boanerges Aleman-Meza

These are (some of) my favorite places to eat in Houston Texas. (In no particular order)

  • Blue Nile Ethiopian Restaurant, 9400 Richmond Ave
    • Skip this when having people that only like americanized food
  • Hibachi Grill and Buffet, 12183 Katy Freeway
    • Toddler friendly menu (which buffet is not toddler friendly?)
    • It has changing station only on women’s restroom
  • Nam Noodles and More, 2512 Rice Blvd
    • Toddler should be able to eat noodles or tofu, and the chocolate cake for sure
    • Some tables have a long sofa-like on one side, which is good for toddler to jump around
    • It has changing station in both men’s and women’s restroom
  • Torchy’s Tacos, 2400 Times Blvd
    • Toddler friendly menu, we like the dirty-chavez because of the egg although the carrots need to be eaten by adult (they are spicy)
    • It has changing station in both men’s and women’s restroom
  • Tofu Village, 9889 Bellaire Blvd #303
    • Toddler can eat rice, tofu (choose either not spicy or mild), pancake
    • It does not changing station in any restroom

Recipe for Mexican green salsa

July 10th, 2013 by Boanerges Aleman-Meza

Adapted from an existing recipe for Mexican green salsa


  • 1 onion
  • 1 clove of garlic
  • 4 tomatoes
  • 2 serrano pepers
  • 20 sticks of cilantro
  • salt


  1. Wash everything
  2. Put a small chunk of onion (approx. 1/8th of the onion), the tomatoes, serrano pepers and the garlic on a frying pan on high flame until they burn a little. For example, the tomato should be cooked enough so that its skin could be easily removed by hand
  3. Blend everything (except the tomatoes), adding 1/4 cup of water and 1/2 tsp of salt
  4. Add the tomatoes to the blender and blend again but only enough so that the tomatoes are sort of chopped instead of fully blended.

Example of Yahoo’s inneficient advertising

December 6th, 2012 by Boanerges Aleman-Meza

If you use mail.yahoo.com, you’ll see ads. The advertisement of Mozilla Firefox takes you to download version 17 of Firefox. However, I am opening the website with exactly that version of Firefox. Hence, such ad is useless. Yahoo’s web server should detect that I already have that version of Firefox. It can even be done in Javascript. Advertising Firefox 17 to users using Firefox 17 is simply inefficient.

August 31st, 2012 by Boanerges Aleman-Meza

I upgraded my linux box to Ubuntu 12.04. The upgrade went smoothly, except for a few screens such as the following:

The new version looks great, very nice design, except that the launch-bar is too colorful. Nice work Ubutu !
