Conklin Sends Softball to Season Opening Split at Catawba
February 15, 2012
Story Courtesy of Catawba Sports Information
SALISBURY, N.C. - Catawba and visiting Pfeiffer split a softball doubleheader on Wednesday afternoon at Whitley Field. The Falcons took the opener 2-0, while the Catawba Indians claimed a 7-1 win in the nightcap. Catawba now stands at 8-2 on the year. Pfeiffer is 1-1.
Catawba scored early in game two to gain the split. The Lady Indians took advantage of three Pfeiffer errors to score three times in the first. A pair of two-out errors led to a run and kept the inning alive for Alli Justice (Bishopville, MD/Decatur HS), who doubled home the final two runs of the frame.
Catawba put together three two-out hits in the second, capped by a two-run double by Tara Gibbs (Waynesville, NC/Tuscola HS) to go up 5-0 after two innings. Justice singled in the third and scored on another Falcon miscue.
Emily B. Huneycutt (Locust, NC/W. Stanly HS) worked four scoreless innings before exiting in the fifth with a runner at second. She allowed three hits with a pair of walks and three strikeouts. Selena Ashley (Walkertown, NC/E. Forsyth HS) finished off the last two and two-thirds innings, allowing a run off three hits.
Justice and Gibbs finished with a pair of RBI with Justice having two hits. Casey Baucom (Marshville, NC/Piedmont HS) stroked three singles in the nightcap for Catawba. Tyresha Ellis (Jefferson, SC/Central HS) drove in the Pfeiffer run with a sixth-inning single.
Melanie Conklin (Wellington, NC) held Catawba to just four hits in posting the shutout in the opener. She walked two and struck out 14. The senior also picked up three hits at the plate and drove in the second run for the Falcons with a double in the third.
Pfeiffer scored the games lone runs in the third inning. Lexie Brock (Knightdale, NC) led off with a single and went to second on a sacrifice. Sadie Saine (Crouse, NC) doubled her in then Conklin followed with her RBI double.
Three of the four Catawba hits were doubles, but the Lady Indians stranded a runner at third twice with one out. Emily D. Huneycutt (Oakboro, NC/W. Stanly HS) led of the second with a two-bagger, but was stranded at third as was Amanda Terry (Cordova, NC/Richmond Senior HS), who doubled with one out in the fifth. Gibbs was left at second after leading off the sixth with a double.
Pfeiffer will now open up its 2012 home portion of the schedule on Saturday and Sunday hosting Brevard at 2:00 p.m. and Wingate at 1:00 p.m.

The no-shampoo method is also referred to as co-washing or conditioner washing. Sometimes it's even called the curly girl method (CG) form Curly Girl: The Handbook, a book written by Lorraine Massey and Deborah Chiel which helps people embrace their natural hair texture. With that objective in mind, Massey described a new and revolutionary routine to get healthy, well-behaved waves, curls and coils.
Although the very best way to do this routine is after reading the book, we understand that many people just can't wait another day because their hair is begging for help. Here are the basic guidelines of the routine to help you get started.
MORE: Curly Girl: The Handbook
Why No Shampoo?
Most commercial shampoos contain sulfates and surfactants that are too harsh for our hair and tend to rob our hair of moisture.Curly hair tends to be more porous than straight hair, which makes rinsing out all traces of shampoo virtually impossible and causing frizz. Many conditioners also contain mild surfactants which, paired with a little manual friction, can lift off dirt, debris and excess oil from our scalp and hair.
To make a shampoo free routine work, you should eliminate the use of most silicones ('cones for short) from your hair care routine since most can only be removed with harsh shampoos. Washing with a conditioner while using them would cause them to quickly build up on the hair, which results in dull, matted hair and poor curl definition.
MORE: Sulfate Free Shampoos
Choosing a Conditioner
It is very important to choose a good conditioner if you're going no shampoo. Here is what you should look for on the label:
Emollients soften, smooth the hair and give it shine. There are hundreds of them, including such natural emollients as vegetable oils and nut butters. Widely used emollients include glycerides and liposomes.
Proteins temporarily "repair" the hair and/or protect it. Occasionally proteins will build up on some people's hair, especially on healthier hair. In this case, alternate with a protein-free conditioner. Examples of proteins include silk, soy, wheat, keratin or individual amino acids (components of proteins).
Humectants absorb water and hold in moisture. They are absolutely crucial in a conditioner for curly hair. Panthenol, vegetable glycerin, sorbitol and honey are just a few humectants to look for on the label. Moisturizers soften and control to curly hair. Amino acids and aloe vera are two great moisturizers.

Detroit � It�s fashionable to say it, and perhaps reasonable to think it. The Tigers have one big nagging injury, and a few bullpen blips and lineup lapses. They�re not exactly churning into the postseason, so naturally, they�ve turned from World Series favorites into a wounded bunch just hoping to hang with the A�s, right?
Nice try. Sorry, but I�m not taking a smidgen of truth, sprinkling it with hyperbole and baking up nonsense. No, the Tigers aren�t huge favorites now, but one thing hasn�t changed, and their fate will be decided exactly where it began � on the mound. For the Tigers, that�s still a great place to start.
It begins with Max Scherzer in Game 1 on Friday night, a surprise to absolutely no one. Jim Leyland made the announcement Tuesday, and he must have felt like a cook selecting prime cuts of beef. After Scherzer, the presumptive Cy Young winner, it will be Justin Verlander, the MVP and Cy Young winner two years ago. And then oh, by the way, the league�s ERA champ, Anibal Sanchez, will start Game 3 in Detroit on Monday.
Listen, the Tigers have reasons to be concerned, starting with Miguel Cabrera�s limp. They eased messily down the stretch, capped by that no-hitter by some anonymous Marlins pitcher, although it�s silly to alter perceptions based on the final week (or final month).
Don�t forget what rules the game. Here�s a helpful suggestion: Every time your knees buckle when you see Cabrera�s legs buckle, take a long look at the rotation. It�s the best in baseball, arguably. It�s the most menacing in baseball, inarguably, as the Tigers struck out more batters than any rotation in history.
Leyland�s playoff order makes sense, with Doug Fister at No. 4 and Rick Porcello going to the bullpen. At 21-3, Scherzer was an obvious choice. Sanchez was alternately spectacular and solid, but Verlander at least is getting closer to being Verlander again. He pitched 12 scoreless innings his last two outings and his ERA is down to 3.46. And I�m sure it mattered he was superb in shutting out the A�s in Game 5 in Oakland a year ago.
The order doesn�t even necessarily make a difference because either Scherzer or Verlander could start a Game 5 on normal rest.
�If it was me, I�d probably make the same decision, because Max has had a magical season,� Verlander said. �When a guy�s had a season like that, why not ride it? We�re all a team here for one single goal, and that�s to win a World Series.�
Money on Oakland
It�s impossible to heap more pressure than the Tigers already bear, but I�ll do it anyway. Their starters have to be excellent to beat the A�s, who won 96 games and clobbered them in a four-game late-August series, winning three while scoring 34 runs. This is a tough matchup for the Tigers, just like last year, but don�t listen to me. Listen to the ESPN experts � 22 of 33 picked the A�s.
Starting pitching can cover up many deficiencies but not all, which is why a return to the World Series won�t be easy. The A�s finished with a better record again, have their noisy home-field advantage again and are a feisty bundle of scruff and guff again. But they have their own issues with slugger Yoenis Cespedes� sore shoulder, and if the Tigers have to win 2-1, 1-0, 1-2, 0-1, 2-1, so be it. If their starters have to throw 125-pitch complete games, as Rays ace David Price did the other night, October is the month to do it.
�On this staff, you really don�t have one guy � we have a bunch of guys that can pitch extremely well,� Scherzer said. �You gotta be aggressive with (the A�s). They�re patient, they grind out at-bats, they can run your pitch count up. That puts the onus on you even more to attack them with strike one.�
Grind time
Detroit�s starters were first in the AL in ERA at 3.44, and Oakland was second at 3.72. The A�s will send out a far more eclectic (and less stable) mix, from 40-year-old ace Bartolo Colon to hotshot rookie Sonny Gray to 24-year-old Jarrod Parker, although they do have a better bullpen.
The Tigers hitting has been so spotty, they welcomed back Jhonny Peralta and likely will toss him into an unfamiliar role in left field. For comparison, the Tigers led the AL in average (.283) and second in runs behind the Red Sox. The A�s, who draw walks and steal bases, scored 29 fewer runs despite posting an average (.254) nearly 30 points lower.
The Tigers will have to do some grinding here. The way Cabrera winced his way though September with one home run freaks people out, which is understandable. Battling a groin strain, Cabrera said he was feeling better Tuesday, but there�s no doubt he�ll be slowed.
The Tigers have been an all-or-nothing team, loaded with thick-legged boppers and thunder-throwing pitchers. Their offense: Home runs and really long singles. Their identity: Pitchers who take the ball and hurl it hard. At the end of a long season, at the start of a tense postseason, not a lot has changed. It�s imperative the Tigers do what they do, and throw like they throw.

About 43 years ago or so, Robert "Bob" Armstrong walked into Matt's El Rancho in Austin and asked the owner's son, Matt Martinez, Jr., to surprise him with something new. Bob Armstrong was the Texas Land Commissioner at the time, and was not only a powerful guy but also a regular customer. Matt wanted to make him happy.
The story goes that Matt went into the kitchen, grabbed a large bowl and ladled into it some taco meat. Next, he hid the taco meat under a generous helping of creamy chile con queso and finished with dollops of guacamole and sour cream on top. He then took the bowl out to Bob and presented him with his kitchen creation.
At first Bob looked at the bowl, wrinkled his nose and said, "That's just queso. I wanted something different!" But Matt insisted he try it and when Bob dipped his chip into the queso and discovered the layer of taco meat, he grinned and proceeded to eat the whole bowl without further comment.
The next day, people came into Matt's El Rancho asking for a bowl of Bob Armstrong's dip. None of the wait staff knew what the heck they were talking about until Matt Martinez, Jr. figured out they were asking for the off-the-menu queso he'd made for Bob the day before. Apparently, Bob Armstrong had returned to the Texas state capitol and told everyone they had to try Matt's queso with taco meat, guacamole, and sour cream. And at that moment, a chile con queso legend was born.
In later years, other queso compuestos, as that genre of chile con queso is called, also rose to prominence—quesos such as Kerbey Lane's Kerbey Queso topped with guacamole and pico de gallo, and Magnolia Café's Mag Mud with its refried black beans layered into the silky cheese. But Bob Armstrong Dip, as Matt's queso creation is now officially known, may just be my favorite.
You can now find Bob dip in both Austin and Dallas, where Matt Martinez, Jr. later moved to open a few restaurants of his own. And it was there that I actually first encountered it, as in college we'd eat at Matt's Rancho Martinez in Lakewood and spend lazy afternoons on the patio enjoying hot queso and cold beverages.
A few years ago my college friends and I had a reunion in Dallas, so it seemed fitting that the first order of business was lunch at Matt's. I headed straight there from the airport, and it was a welcome sight to see not only my friends but bowls of Bob dip at the table. It felt like no time had passed at all.
Now, you may have heard that there's a Velveeta shortage, and for many folks this is something akin to a tragedy, as everyone knows that a block of Velveeta along with a can of Ro-Tel is the quick path to queso happiness. That said, living in New York I've long suffered a Velveeta shortage as it's never been easy to find here, so many years ago I learned to make do without. A more natural chile con queso was the result of my kitchen experiments, and it's pretty good, if I do say so myself.
That said, Bob dip also doesn't use Velveeta. Nope, in Matt Martinez's books "Matt's Culinary Frontier" and "Mex Tex" he provides recipes for his famous dip and he calls for just plain American cheese. While anytime is queso time, in my opinion, I do know that many especially enjoy it this time of year, so I decided now would be a fine time to try his recipes.
First, however, I made a couple of changes. For one thing, I decided to forgo the diced celery he called for, which just sounded strange. Also, his taco meat was lightly spiced with only cumin, salt, and pepper, but I found it a bit bland so I added a couple of shakes of chili powder to make it a bit more robust.
In the end, however, when I assembled the queso (keeping the taco layer hidden as it was in the original bowl presented to Bob Armstrong), and then dipped my first chip, I was back in Texas enjoying a sunny afternoon with old, dear friends. And it doesn't get much better than that.
Ingredients for the taco meat:
1 tablespoon vegetable oil
1/2 bell pepper, seeded, stemmed, and diced
1 jalapeño, seeded, stemmed, and diced
1/2 small yellow onion, diced
2 cloves garlic, minced
1 pound ground beef
1 teaspoon ground cumin
1 teaspoon chili powder
1/2 teaspoon kosher salt
1/2 teaspoon black pepper
Pinch of cayenne
Ingredients for the guacamole:
2 Hass avocados, peeled and pitted
1 tablespoon freshly squeezed lime
1 teaspoon chopped cilantro
Ingredients for the chile con queso:
1 tablespoon vegetable oil
2 jalapeños, seeded, stemmed, and diced
1/2 small yellow onion, diced
1 clove garlic, minced
1/2 teaspoon ground cumin
1/4 teaspoon black pepper
1 tablespoon corn starch
1 cup chicken broth
1 pound American cheese, shredded
1 cup grape tomatoes, diced
Sour cream, for garnishing
Tortilla chips, for serving
To make the taco meat, in a large skillet heat the oil on medium-low heat and add the bell pepper, jalapeño, and onion. While stirring occasionally, cook until the onion is translucent, about 5 minutes. Add the garlic and cook for 30 more seconds.
Add the ground beef to the skillet, along with the cumin, chili powder, salt, pepper, and cayenne. Stir until everything is well combined and then cook the ground beef for 15 more minutes, or until browned. Taste and adjust seasonings. Turn off the heat and drain any excess grease.
Meanwhile, to make the guacamole, mash together the avocado, lime juice, and cilantro. Add salt to taste.
To make the queso, in a saucepot heat the oil on medium-low heat and add the jalapeño and onion. While stirring occasionally, cook until the onion is translucent, about 5 minutes. Add the garlic and cook for 30 more seconds.
Leaving on the heat, stir in the cumin, black pepper, and cornstarch until the dry ingredients are well combined with the vegetables. Pour in the chicken broth and while stirring cook until the sauce has thickened, which should happen in a couple of minutes.
Turn the heat down to low and working in batches, slowly stir in a handful of the cheese. After it's melted into the sauce, repeat the process until all the cheese is added. Stir in the tomatoes, adjust seasonings, and add salt to taste.
This makes a lot of queso, so you can either serve it in individual bowls or in a larger dish, such as a 9-inch square dish. To assemble, layer along the bottom of the dish the taco meat, then pour in the queso and then top with the guacamole and sour cream. Serve warm with chips.
10-12 servings

I think that presenting something that looks just like the queso we've been eating (which has been enormously popular) but which actually has a hidden meat layer sounds like the perfect way to kick things up for the Super Bowl.
- Lisa (Homesick Texan) said...
Laura--Taco meat will definitely work in the more natural one, as well. I'm so glad to hear y'all have enjoyed it!
- Amy in Austin said...
Being a native Austinite, I can absolutely appreciate the sheer glory that is a fresh bowl of Bob. We celebrate most family occasions at Matt's, and tradition is that my brother be the one who gets to make that first stir. You just can't go to Matt's without getting a bowl of Bob. Thanks for sharing your take on it- this will be the perfect dish to share at our Super "Munchie" Bowl Party.
- Ashley in MD said...
Oh my gosh, thank you! I am also a homesick Texan (I've lived in Maryland for six years now) and I have such fond memories of hanging out at Matt's El Rancho with family and friends drinking prickly pear margaritas and filling up on this dip. I am absolutely recreating this for the Super Bowl!
- Lisa (Homesick Texan) said...
Amy--I love that your family has a tradition of letting your brother make the first stir!
Ashley--A taste of Austin in Maryland--it should be a delicious Super Bowl! - 2:49 PM
- DessertForTwo said...
I'm pretty sure I could polish off a whole bowl of this by myself!
- Lisa (Homesick Texan) said...
DessertForTwo--Speaking from experience, that is not difficult to do!
- Rocky Mountain Woman said...
I think this just went on my Super Bowl menu....
yep, it did! - 3:47 PM
- Lisa (Homesick Texan) said...
Rocky Mountain Woman--It's a fine edition to your menu. Enjoy!
- Not Your Mama's Martha! said...
Another native AUSTX girl (living in San Francisco for the last 8 years) who is in-love with this recipe and your entire blog. I'm really looking forward to your book, congratulations - it will go a long way in helping to explain the awesomeness that is TexMex that people all over just don't get. I can't wait to make this!
- Emily H. said...
I'm currently living in Houston and only get to Austin every few months, but you better believe the first place I stop whenever I'm in town is El Rancho for a big ole Bob. Thanks for the wonderfully nostalgic post :)
- meganrhyne said...
I lived in Lakewood Heights in Dallas, and I remember how "in" I felt when I learned to order Bob Armstrong, which wasn't on the menu, at Matt's. And I loved it. Thanks!
- Unknown said...
Bob Armstrong dip is by far, my favorite! I was first introduced to it at Mattito's in Uptown Dallas and have been hooked ever since. It was our go to appetizer on birthdays and other special events. Now that I'm in NY, this will great way to warm up for the Super Bowl! Thanks!
- Lisa (Homesick Texan) said...
Not Your Mama's Martha--Tex-Mex is indeed awesome. Thanks for spreading the word in San Francisco!
Emily--You're welcome. It's always a first stop for me, too! - 9:52 AM
- Lisa (Homesick Texan) said...
Megan--Yep, I remember those days. You'd order it and then wonder who was Bob Armstrong.
Unknown--You're welcome! I have to admit that I've never been to Mattitos--I need to go there next time I'm in Big D. - 9:53 AM
- Smalltowngirl said...
Just had this yesterday at lunch...we call it queso compuesto here in my small town (West Texas). Yummy stuff!!
- Lisa (Homesick Texan) said...
Smalltowngirl--The first time I encountered the term "queso compuesto" was in Marfa. It's definitely a West Texas thing!
- Anonymous said...
Just died and went to heaven. Thanks, Lisa!

- D.L. Thomas said...
We eat this a lot at most rest. in Houston, and I've made it many times. New recipe for me to try. I'm wondering about the American cheese? Sorry but I only know about sliced American cheese that comes in a package. Is this cheddar I guess?
- Lisa (Homesick Texan) said...
Debra--You're welcome!
DL--I got my American cheese from the deli department at my supermarket. They can cut you a 1-pound block that's easier to shred (and less expensive) than using the pre-wrapped American cheese slices. - 11:14 AM
- Mary said...
Yes the blue box American cheese is usually next to the yellow Velveeta, is grateable and is also fantastic for mac n' cheese.
- Jenilu said...
Love queso, my late dear Hubby made it always during superbowl, but he added browned jimmy deans hot sausage to the crockpot then the rest of the ingredients and let it crock!! Yes queso compuesta is very popular in Corpus Christi. One nice place has it with seafood or other yummy meats. :-)
- Tamara said...
I just found your blog, via Smitten Kitchen.I grew up in San Angelo, Tx but have been away from TX for about 11 years. Im so excited to dig into a bowl of Bob soon ... and all your other recipes! Thanks!
- erica said...
The lovely people at Matt's will graciously accommodate a non-meat request for this dip by subbing the taco meat with refried beans. It's delicious too!
- Unknown said...
Thanks for the background story on the name of this dip. My uncle was Bob Armstrong – not the one whose name is on this dip – but when I first saw this on the menu, I thought maybe he was better known than I thought. :-)
- janmaus said...
I lived in Austin between 1985 and 2000, but only had this queso version in Dallas. Of course, most of the time in Austin, we ordered queso fundido con rajas, so it was our own fault we missed this deliciousness
- Lea Ann (Cooking On The Ranch) said...
I love a good recipe with a good story. Thanks for sharing.
- Robert said...
Dear Lisa - thanks for this post AND the recipe. I fondly recall Matt's and the then "off-the-menu" Bob Armstrong dip from when my wife and I lived in the Lakewood neighborhood. Now we've been in beautiful [really] Glen Ridge, NJ for almost 20 years, [current temp = BRRRR]. What do we miss most? Good Tex-Mex & BBQ. We WILL be trying this recipe at home in the near future.
- Gail Morton said...
During a recent lunch at Matt's, a nice looking gray haired gentleman was walking around, sipping a margarita. He stopped at our table and introduced himself as THE Bob Armstrong! Pretty cool!
- Anonymous said...
I grew up just south of Austin in San Marcos, and never knew about Bob dip. Will make some tonight!
- Janus said...
There's a Velveeta shortage? It must be only in certain areas, because there is plenty of Velveeta in all of the supermarkets in my area. Not to mention the various store brand versions thereof.
- Anonymous said...
Not only does this sound like a terrific spin on queso, who can turn down a glorious snack so popular it can simply go by it's first name?! Bob, welcome to our Super Bowl party! Thanks.
- Cindy said...
This sounds so good....I have made "American cheese dip" in years past and never thought of using for this....duh....like the idea of using beans too....next trip to Texas I am definately going to try this restaurant! Love your blog!
- David Lloyd said...
"Bob" and I have been friends for over forty years.
In the late 'sixties to mid 'seventies my parents lived in San Antonio, and I would drive there from my home in Fort Worth every two months. Always—ALWAYS—I stopped in Austin (coming and going) to eat at Matt's El Rancho. One afternoon I overheard Matt Jr. talking with a man about his layered queso dip. That man I later found out was Bob Armstrong and he was telling Matt how to make it for him. Matt disappeared for a while and came back to serve Bob a big bowl of the stuff. I thought it looked great, but I had already eaten, so I paid up and left. When I returned to Austin a couple of months later everyone was eating it. And so have I ever since.
- Shelley said...
If you were on a desert island with one avocado and could choose one spice to have at hand--what would it be?
- Stacey said...
We always get at least two bowls of this wondrous creation at Alamo Café in San Antonio. I can't wait to make it myself Sunday, with chorizo of course.
- Carol said...
My husband and I ate regularly at El Rancho for years but somehow missed the Armstrong queso. Now we live in Wisconsin so I have to make my own Tex Mex (easy to do with your wonderful recipes). We tried the queso last night with soy crumbles instead of taco meat and it worked out really well. Had to restrain ourselves from scarfing it all down in one sitting. Thanks!
- purplerangerfood said...
That's one small dip for a Texan, one giant dip for Texaskind.
And on a slightly different note, YAY! You and Grilled Cheese Social both posted new entries the same day! - 7:40 PM
- Jennifer Robinson said...
LOVE! I just found your blog and this is the first post? So fun!
Bob is my favorite. I'm in Dallas and my husband and I have a nerdy tradition of stopping at Matt's for Bob and margaritas after every trip. I never thought of making it, but I'm definitely going to try!
- Anonymous said...
Hi Lisa, make your way to Brooklyn for velveeta... this supposed shortage must have skipped us, as both the Key Food and Foodtown in Williamsburg were both stocked FULL as of this week... I think the shortage was used to drum up press for queso. Which, as a homesick Texan myself, I wholeheartedly support.
All the best,
Tom - 5:17 PM

I eat at Matt's (the original) several times a month and they've never put sour cream in the Bob Armstrong dip (side note -- Bob still comes into the Austin location and told me once that he only put guacamole in his dip when he started asking them to make it this way and that Matt (the older one) put the taco meat in it later when customers asked for it -- I'm not saying which story is true and Bob's memory may be fuzzy). Regardless, do they make this dip differently in the similarly named restaurants outside of Austin? I'm not sure if they're all same as Matt's Original El Rancho, so it could be some sort of legal issue where the others have to add sour cream? Not sure why I'm so interested in queso this morning.
- Lisa (Homesick Texan) said...
Mary--Good to know!
Jenilu--That's a fine addition to queso!
Tamara--Happy cooking!
Erica--Thanks for the tip!
Unknown--Ha, what a great story!
Janmaus--I'm also a fan of queso fundido.
Lea Ann--You're welcome! - 11:15 AM
- Lisa (Homesick Texan) said...
Robert--Yep, that's what I miss, too.
Gail--Very cool indeed!
Anon--It's never too late!
Janus--Yes there is in some parts of the country.
Anon--It's a great name!
Cindy--Yes, I can't wait to try it with beans myself.
David--What a great story! Thanks for sharing!
Shelley--One spice for my avocado? I don't generally add spices to my guacamole though I would hope garlic was available. - 11:18 AM
- Lisa (Homesick Texan) said...
Stacey--Chorizo is a fine addition!
Carol--Oh, that's good to know it's terrific with soy crumbles!
Purpleranger--Glad you're happy!
Jennifer--That's a fine way to welcome yourselves home!
Tom--Good to know! I haven't seen any in Manhattan but it's always hard to find here. And yes, I wouldn't be surprised if you're analysis of the situation is correct. It certainly received a ton of press!
Anon--The story and recipe I based my post on came from Matt, Jr., so who knows? - 11:23 AM
- Irishaggie said...
Awesome. When I was growing up in East Dallas my folks and I would frequent Matt's and we ordered the Bob Armstrong. It was never listed on the menu. Thanks so much for posting this recipe. Homesick in Portland, OR.
- Lupita Laber said...
Love your blog and recipes. How would you recommend serving this for Super Bowl party so it stays warm? In a crock?
- Lisa (Homesick Texan) said...
Irishaggie--I remember those days!
Lupita Laber--Yes, I'd keep it in a slow cooker. - 10:46 AM
- Anonymous said...
Does this need to be served fresh or can I make it the night before and slowly reheat the next day?
- Lisa (Homesick Texan) said...
Anon--You can make-ahead the taco meat and the queso and then reheat but I'd make the guacamole the day of your party.
- LB said...
Thanks for the lovely Matt's flashback! My (homesick) Texas boyfriend and I live in Boston but used to live near Lakewood (Lower Greenville right on Oram St.). I'm making this as soon as I can get to the store to help us get through the next snow storm.
- girlplusdog said...
I agree, thanks for the lovely flashback! I miss Austin and Texas!
- Liz said...
On a sad note - Bob Armstrong passed away Sunday (3/1/15). He will be missed.

Pet supplies retailer Zooplus grows web sales 35.5% in Q1
Total sales in 2015 are expected to reach $811 million.
Retailers that act now can receive reduced prices for online ads.
Consider this fair warning: A set of discounts offered by Google for its new—and non-free—comparison shopping service are about to expire in the coming days.
In case you've been off the electronic leash in some tropical utopia of seclusion for the past few months—in which case I would like to offer my services as your personal assistant, assuming travel is included, and no smartphone or e-mail use required—you know that Google is replacing free listings on the Google Product Search comparison shopping service with paid product listings ads through a new online program called Google Shopping. This isn't some slow-moving plan. This is happening now, and e-retailers have already reported sharply reduced traffic from Product Search. A full report on those changes, the reasons behind it, and what retailers can do to thrive in the new environment, will appear in the September issue of Internet Retailer magazine. In the meantime, you can read more here or here.
No one likes it when things that were generally free become things that generally cost money. You should have heard all the compound curses that I crafted when I realized that listening to the streamed baseball broadcasts from my hometown required me to fork over just a bit more scratch to the baseball-industrial complex. But Google's having a sale, and you should know about it.
Here's the deal: Google is offering merchants that create product listing ads by Aug. 15 a monthly credit for 10% of their total product listing ad spend through the end of 2012. Google also is offering merchants that now take part in Product Search $100 worth of credit toward their Google advertising; that promotion also expires Aug. 15. Merchants interested in the latter can find the required form at http://www.google.com/ads/shopping. Google won't say how many retailers have taken advantage of those incentives; the company's representatives will offer only that the company is "excited about the number of retailers that have signed up for Product Listing Ads since the transition to Google Shopping was announced in May, and about the range of products offered by these companies."
Good luck with Google Shopping, and please remember me when you exile yourself to the South Pacific.

After the meeting, Oklahoma Rep. Tom Cole told reporters that Boehner said: "I've stayed out of those negotiations."
"Every time we get involved in them, we sort of get burned, so we're going to let the Senate work its will, see what they do and what they send us, and we'll act accordingly," he said.
Sen. Chuck Schumer, D-New York, told ABC's "This Week" he thought the chances of a short-term, last-minute deal brokered by Senate leaders were better than 50-50.
"I've been a legislator for 37 years, and I've watched how these things work on these big, big agreements," Schumer said. "They almost always happen at the last minute."
And Sen. Lindsey Graham, R-South Carolina, said the chances are "exceedingly good" that some type of deal will be reached by Monday night.
"I think, whatever we accomplish, political victory to the president, hats off to the president. He stood his ground. He's going to get tax rate increases, maybe not $250,000, but upper-income Americans," Graham said on "Fox News Sunday."
"And the sad news for the country is that we have accomplished little in terms of not becoming Greece or getting out of debt."
Other Republicans argued Sunday that Obama's plan hasn't done enough to limit spending.
"The president is doing nothing about the addiction that his administration has to spending. He's the spender in chief," Sen. John Barrasso of Wyoming said on CNN's "State of the Union."
Obama told NBC that he has cut more than $1 trillion in spending and offered another $1 trillion-plus in additional cuts "so that we would have $2 of spending cuts for every $1 of increased revenue." He said the majority of Americans have made clear they support his calls for "a balanced approach" that would increase taxes on the wealthy.
Sen. Dick Durbin, D-Illinois, warned that now is "exactly the wrong time to go over this cliff."
"We are in the midst of an economic recovery. We are seeing new job creation, businesses are seeing new growth, we are seeing the kind of economic indicators we've been waiting for for years. This going over the cliff is going to bring uncertainty to our markets, and with that uncertainty, a pullback in consumer confidence and a reduction, I'm afraid, of business activity and the creation of new jobs," he said.
But former Democratic Party chairman and 2004 presidential contender Howard Dean told ABC that heading over the cliff would not be so bad, calling it a "fiscal curb" instead.
"You go back to the Clinton tax rates, and you make some significant cuts. And you cut the Defense Department, which hasn't been cut in 30 years," said Dean, a former Vermont governor. Meanwhile, going over the cliff gives Obama more leverage, "because then all of sudden, middle-class people's taxes are going to rise, and that's going to be bad for every politician in Washington."
"Maybe they'll actually get something done," he said. "But I think, at this point, at this late hour, I think almost any deal they come up with is worse than going over the cliff."
Sen. Olympia Snowe, R-Maine, told CNN's "State of the Union" that she expects Congress will vote to extend tax cuts for incomes below $250,000 -- perhaps below $400,000 -- before midnight Monday. A Senate agreement "would build momentum" for the move in the House, she said.
"I think it would be horrific for the country if at this time, the final days of this legislative session that already has reached historic proportions of failure, that we would now culminate in failure to extend these tax cuts," said Snowe, who is on her way out of office.

And I did support the humble bundle. Aquaria is very neat. But I did't come to test the other games yet.
Phoronix: Aquaria Game Source-Code Published
Last month we reported on four indie games going open-source that were part of the pay-what-you-want "Humble Indie Bundle" after the developers experienced very favorable returns. The source-code to Aquaria has now been published with the source-code to the three other titles (Lugaru, Gish, and Penumbra Overture) already being available...
And I did support the humble bundle. Aquaria is very neat. But I did't come to test the other games yet.
For the Gentoo users among us, I did start working on ebuilds for the open source games but got sidetracked with trying to bring Penumbra: Overture to x86_64. This required porting it to version 2 of the Newton physics engine. It builds and runs now but touching anything results in insta-death due to broken collision code. XD It is hoped that either me or the guy who originally ported it to Linux will be able to figure it out. I'll try and find time to make ebuilds for the other games too.
Thanks Chewie that will have me emerge them soon.
Chewi you rock
Your kind comments inspired me to work on Aquaria sooner than I might have. I've just completed an ebuild for the engine. I'll get it uploaded once I've completed the ebuild for the game.
I may well take you up on that sooner or later! Thanks.
I've got the game running now and in 64-bit, thanks to additional work by Ryan and others. I've only played it for about 5 seconds but it seems to work. I still have some finishing touches to put on the ebuild but it shouldn't be long now.
Which game? Aquaria?
In any case, cool work!

Well I guess that depends on what you consider contributions. Amd contributes more back to GCC then intel (which is one of the reasons why GCC does a good job on AMD processors where intel favors it's own compilers) , intel seems to contribute back to X (almost to ruling it with an iron fist), AMD sponsors some distro's with build servers, mirror servers and such. AMD and Nvidia have contributed back to openCL, intel hasn't done alot in that area. I don't think you can draw a clear cut, who gives more as contributions come in many shapes and forms.
Lets not forget that by supporting the 10,000 ton gorilla instead of the smaller guy that needs that financial aid isn't going to help out their ability to contribute back either.

Thanks Jack.
Great lectures Jack!
Jack this was very good
Great presentation and very informative lecture. Thank you Jack
Great presentation.
now, i have to take a sleep and i will continue day 3 class tomorrow...
thanks to digikey and design news for this class for us accumulating PDH Certificates...
goodnight and good morning to all you guys and our dearly sir jack and sir alex...
GREAT PRESENTATION Sir Jack...i do enjoyed listening the lesson and discussion answering the questions so far...
now, i am in slide 35 and finishing the day 2 class lesson...thanks sir jack for a wonderful presentation...
i am now on a very interesting lesson slide 20...
i am now on slide 19 of the lesson...
just downloaded the presentation slides and now i am starting with slide 2...
good evening sir jack! i will continue now with your lesson for day 2 class...
Thanks for clarifying that cache is considered non-deterministic.
Thank you Jack and Alex, very nice presentation, good information too.
Thanks Jack and Alex. I learn lots of concepts on multicore arena.
Great presentation understand some things bettter now.
Thank you for great seminar!
Perfect, lots of inside-out experience!
Hi again!
THanks Jack.
Yes, so many projects are done with the existing hardware and familiar software tools with no thought about speed and efficiency -- or whether the processes involved are parallel.
I loved the Feature Management slide -- and the part about giving management some options.
Good presentation! Partitioning is a key design strategy. IOP's (I/O Processors) are a common architectural implementation, perhaps not common enough. Partitioning means ownership, ownership (presuming 'buy-in) means accountability, accountability means interest and dedication (not that it isn't there otherwise, but harder to maintain). Partitioning makes for easier design and debug, supportability and future product enhancements.
All this presumes someone cares and there is something to care about. I hope many are opting out of the widget, gadget and whatchamacallit industries and looking for serious socially responsible engineering opportunities. My main concern is the power grid and how societally power is used (and mis-used) and the attendant problems that will come with it. Portable applications notwithstanding, devices, including batteries need to be powered from somewhere ...
Thank you Jack and Alex for another great lecture.
I can't even imagine 192 processors running together! How is the work divided?
How is it that we have created cache that is so much faster than storage memory, but we still cannot significantly increase the speed of storage memory?
They had the same sound problems today too, huh?
Hello everyone.
Is there any difference between Firmware and software ?
Thank you, Jack - great presentation.
Are their ways to detrmine which elements are parallelizable?
Well done, Jack.
Are timing issues more prevalent within a multi-core device or in multiple single processors combined on a single PCB?
Many core computers are becomming more and more like super computers and we could be able to afford a super computer like a desktop in the near future.
I've heard that GPU's are more efficient at doing computational tasks that CPU's aren't designed to do.
Multicore design is getting easier and soon you can get code developed for multicore systems off the internet.
There are many differences between Firmware and Software and Jack mentioned most of them.
Thank you.
Thanks for claryfing the firmware and software difference
Great presentation, thanks!
Good info!
Thanks for valuable infomation
Alex, PDF slides please, and add a "flipped slide" noise to the presenter's powerpoint, so we know when he flips.
Thanks, Jack!
manya, I would be more concerned about whether the board manufacturers correctly supply the USB bus in the circumstance you describe. It strikes me as an edge case that a manufacturer would forget about, and either not test against, or not even implement. That would not bode well for a product.
Thank you Jack and Alex
thanks all it was a great lecture
Thanks Tenacious.
Tenacious, I agree to a certain extent, thats why Ia minterested in negotiating with the host rather than blindly trying to source 900mA. The USB 2.0 spec specifies that the port will shutdown automatically if more than 500mA is requested unless the HID negotatiates. USB 2.0 connectors are rated at 1500mA.
Bye everybody.
On the definition of firmware, I stand corrected, Jack. ;) Although, one might guess that my definition might be correct sometime in the future. :)
THANKS JACK. I learnt lot of concepts on multicore arena. Bye for today.
manya, there are chips from just about every manufacturer that do USB out of the box. Try using the chip sorting tools from Digi-Key or Mouser to find cheap chips from your preferred manufacturer that include USB.
snandu, the 300 LOC is in a project setting. That is important. If you have time going to meetings, developing requirements and testing procedures, that is what Jack was meaning. If you do a simpler project on your own, and all of the documentation goes in your head or is minimal, you can easily get higher than the 300 LOC per month.
what is the difference betwwen firmware and software.
Well, my definition is that firmware is software that runs on an embedded system. And since I wrote the dictionary (The Embedded Systems Dictionary) that stands!
manya, I think snandu is right... you want to limit yourself to 500 mA, even if it is theoretically possible to use 900 mA in some cases. No one is going to know whether their USB ports are on a hub or not.
tenacious techhunter from what you said they are almost the same
@Snandu13, USB 2.0 specification states 500mA - 900mA.
Jack whats the best way to implement USB connectivity in an embedded application using a PIC, Atmel, ARM, etc without using a RS232 converter, i.e. to negotatite faster data speed and negotatiate more current from the host (I undersatnd it is possible to obtain 900mA from the host). E.g USB Audio self powered speaker.
That's a huge topic. Check out Jan Axelson's books.
@Tenacious, all I have found upto now are FTDI chips, that do USB/RS232.
Productivity of 300 loc per person per month ( correct and working ) in embedded area appears too low at current times. or am I too ambitious?
Well, the numbers vary a lot, but this is over the entire life of the project, not just coding.
Here here! PDF slides! I insist!
Manya, I thought 500 mA is the maximum you can draw from a single host USB. !!
I am using Google docs to view the powerpoint slides and it looks like the translation process from native Microsoft format is a bit lacking. Any way we could get PDF versions of the slide decks posted?
manya, there is probably an HID device driver for that. Just use a chip that does USB out of the box, build it as the standard device, and you should be fine.
snandu, that number is the lines of code that are absolutely correct, and never need to be corrected. If you ever correct that line of code again, your number for that month goes down.
Jack, from your discussion about partitioning and breaking projects into subsystems, the requirement definitions and for each subsystem becomes extremely important to make sure you have the interface between them defined well.
Bye, everyone.
kenstan, the difference is mostly where the code "lives"... if it is read from embedded flash or an eprom, it's firmware. If it is read from a disk or removable storage, then it's software. But frankly, there isn't much significant difference. One would presume that you want underlying system behavior to be in the firmware, but it doesn't have to be so.
Great selection of complex topics as expected. Thanks a lot, Jack!
In multiple cpu embedded system, we need to write firmware for each cpu independently and interactively. Is my understanding correct, Jack?
Yes. And that means build times go way down, saving more time.
Jack lets say, a 3 axis CNC machine, three PIC 16F's are used to drive each of the motors and a 4th PIC is used to communicate between each driver board and the computer running the cad software. Would this be more effective than a single PIC doing all tasks.
That's a classic case for using all of the PICs. It's exactly like the assembly line. If cost isn't everything, I'd use the four parts.
The key then is from the design stage for the problem at hand; evaluate whether can be best handled serially or if there are intense processing which require minimal shared resources.
As shared resources for each section indicate very high cohesion, it is probably best to employ single controller architecture and cache.
I assume also that the timing of each potentially partitionable task will also be of concern to avoid bottlenecking.
Jack, any experience with multi-master I2C and multi-core?
No, though it introduces more complexity, I'm sure it could be done.
Jack, what happened to "bit slicing"? Anyone still pursuing that route?
Ah, the old AMD 2900 series! It faded aways as CPUs got faster.
Is there a good reference on the web (AKA free) for the cocomo method and how I might translate it to pertain to synthesizable digital design?
I'm sure there is. Barry Boehm was the guy who started it. But it's really tough to use in the real world as you have to calibrate so many constants to your outfit using empirical data.
jack what do you have to say about protues as a stimulation tool
Sorry, not familiar with it.
In an embedded system, would connecting multiple (say 2) PIC16F chips be more effective at running tasks than having a single larger PIC?
It all depends on the application. I wish I could make a general statement, but can't.
jack, anything coming down the pike that would put multi-core CPUs on a switched fabric instead of a system bus? In particular, I'd like to be able to do multiple simultaneous interrupts.
Look at ARM's AHB. It's pretty amazing.
For SPI/UART simulation, go to opencores.org and download one. Most run pretty easily with Icarus Verilog
Jack, do you see a point in time when cheap memory will mean faster?
Speed tends to go up, but there are fundemental limits (gads, I sound like Newt!). It's hard to move data between chips quickly. So some, like Xilinix, are stacking dies using "interposers" that can support 10,000 connections at high speeds.
Thanks, Jack
Jack, Which is the most comfortable easy to use simulation software for five different communication interfaces ( UART and SPI )?
I've seen people do this with the Keil stuff. Also some folks actually build simulation hardware to toss real data around. It's so easy to do nowadays!
in the "Feature Management" theory (I forget who originally came up with this), the theory says "wild guesses" are based on past experience. they compare this to building a house or other common repetative projects. this too is a trap, because past experiences is most beneficial when you are building the same widget over and over. most software and hardware projects are something that has never been developed before. either you haven't developed it. and/or you are using new and different platform/tools etc.
I might point out that feature management (slide 14) could go one stop further and list future enhancements to later products in the series. This would mesh well with AMP, where the designer purposely allows a place for such enhancements to be "plugged in" to the design with modest effort. Also a good way to manage "scope creep."
Good point! Also, it's critical to have a change control procedure. Changes have cost/schedule implications, and to pretend otherwise dooms a project.
heh ... "scope creep" today means something totally different from yesterday's "creepy scopes" :-)
Jack, any suggestions on restoring determinism to the CPU while taking advantage of "improvements" like cache?
That's another Great Unknown. Cache is inherently non-deterministic.
At ARM Techcon, there was a nice demonstration of an asymetric dual core, Cortex M4 and M0, part. The M0 was used for all the I/O like isochronous USB audio leaving the M4 free to do all the audio processing without getting constantly interrupted to support the IO.
That's probably NXP's LPC4350. I have some here and have run some studies that show real advantages to this.
jack21, I work at Tektronix and we refer to FPGA code as firmware and sometimes even software. Part of the reason is that we have real hard-core analog engineers here. It took me a while to get used to this when I first started.
Jack, I asked this earlier: is anyone studiying system identification for cpu allocation?
Some RTOSes offer very sophisticated mechanisms to move tasks between CPUs depending on load. Or one can specify "task affinity," to keep a task on a particular CPU.
I was aware of the low productivity of meetings, Schmiedl, I just wanted some confirmation on how he was looking at productivity. Many people, myself NOT included, consider themselves better than 300 lines of code a month. :)
Jack, thank you, Can a GPU then be used to run normal tasks that would be done by a CPU?
There's a lot of work going on to study this. Some of the next-gen supercomputers will use GPUs.
@manya: theoretically yes, but what would the other 230 cores do in the meantime?
Has anyone considered AMP where the processors have different clock speeds? My laptop has multi-processors which is great for rendering graphics and other processes. But how fast does a processor have to run for word processing when what I'm really doing is typing. Better to have a processor runnig very slowly (I don't type that fast.) and not executing a lot of wait instructions. Slower clocks require less power, longer battery life, etc. as you point out. Isn't having a fast processor asleep and a very slow processor running without a lot of wait cycles preferable to having several very fast processors running a huge number of no-op instruction waiting for me to type the next letter.
That's exactly the idea behind ARM's new big.LITTLE architecture.
Does the industry ever use "firmware" to describe FPGA, CPLD etc. code, (e.g. VHDL)?
I've heard it used that way. But there's no standard useage.
Also, how do you go about making your "wild guesses"?
Do you happen to know what the cocomo constants are for RTL design (Verilog)?
It hasn't been studied.
Homework assignment: go look up the kinds of memory inside a GPU :-)
Any recommended texts on parallel programing using multicore vs multi (independent) microcontrollers environments and inherent consideration of resource management strategies?
I don't know of any.
the real world problem with using the "Feature Management" approach on slide 15, is that management holds you to these wild guesses. They do not understand and do not want to accept the concept of this approach, management are not normally engineers. and what makes matters worse, is that they are WILD guesses. when you actually get into the project, these initial estimates can change drastically, and note, you have already spent appreciable time on the effort. and then, as the effort progresses, there are obsticles you had no way of anticipating. just wanted to point that even though this seems like a very simple and seductive approach to project management, it is very difficult if not impossible to implement in an actual working environment.
Yep. But the only "solution" is complete honesty between them and us. In most companies that doesn't happen. I could go on about scheduling all day!
Thanks, Jack. Very informative.
Jack, How does a GPU differ to a CPU?
A GPU is massively parallel collection of CPUs that are aimed at image processing.
@Tenacious Techhunter: IIRC, the numbers are taken across the complete project, i.e. they take into account the time you spent in meetings or writing docs, where you produce 0 LOC
In embedded system , how do we decide the no of cpus optimally? Then each falsh has to be independently programmed. Am I right?
There's no algorithm to do this; it's all careful design and partitioning of the problem.
any thoughts on this?
according to this definition of firmware even all the complex stacks (eg tcp ip) running on embedded processor are also firmware. Is it so?
This is one of those questions like the one Justice Stevens answered: I can't define pornography but I know it when I see it. Similar for embedded system and firmware. The line is fuzzy, but I'd call all ofhte code in an embedded system firmware.
tomfeliz, if it's not parallelizable, it's because there is a hardware limitation, and for no other reason. Two cores cannot access the system bus at the same time, for instance. Virtualization gets you nothing, in this circumstance. What matters is, is it parallelizable AT ALL? If it is, you don't need virtualization to solve it, though you may prefer that route, if it saves you writing code.
Good Presentation.
Jack, Does a beowulf cluster or blade server use ASMP, limited by the connectivity on the copper/fibre backplane? How would code be compiled to run on each blade/computer?
Mostly these datacenter-like applications use SMP, because these problems (like search) are naturally parallel.
Thanks Jack for the presentation.
So one can imagine that a programmer might do 500 lines of code in a month, thinking that he's better than 300 lines of code, but will only manage to get 300 lines of code correct, and have to rewrite 200?
So another way to think of AMP can be understood with an example in the hardware world where one defines a mechanical or electrical interface, and all components are designed to meet that standard. Think the Common Berthing Mechanism on the space station. In AMP, that interface would be the serial comm with its electrical and protocol standards... And this interface offers the perfect point for testing. One can look toward the outside world and check the data coming in, or feed synthetic data toward the CPU
Tenacious, virtualization allows non-parallelizable tasks to be made parallel. The universe of parallel-friendly tasks is rather small, and it seems like other solutions are needed to exploit multicore for a lot of other problems. For instance, a single low-power Core 2 Duo CPU can run 3-4 VMs very efficiently in less than 20 Watts.
jack21: do you have any experience about using AMP with _large_ amounts of data? How does passing al those bits along compare to retrieving it from memory?
Sure. Large amounts of data problems are common in SMP when the data is very regular (think weather modeling), and in data comm, where AMP works really well. In data comm they often push tens of GB/sec.
Jack, earlier, you mentioned productivity on the order of 300 lines of code per month... Is that the number of lines of code that are absolutely correct and don't need to be rewritten, or simply raw code that might need to be rewritten?
That's completed, working code.
whats difference between firmware and bootloader?
Firmware is embedded code. A bootloader is firmware.
COCOMO = Constructive Cost Model
There Are notes below the presentations, that explains fx cocomo..
Constructive Cost Model (COCOMO)
You mentioned early in the presentation that functions should be limited to 50 LOC or less. Where does this number come from, how was it determined?
50 LOC comes from the observation that we want it all on one page, so we can see the entire function.
Excellent presentation, thank you
Thanks Jack
tomfeliz, virtualization isn't going to solve whether something is parallelizable or not. It either is, or it isn't.
thanks you guys!
Someone asked about tools to make problems parallel - that has been The Great Quest for 30 years.
Thank you! Great presentation.
thanks Jack and all.
What's COCOMO again?
Thanks Jack & Alex!
pic10f is sot-23 package
great presentation. you really have my mind running...
Thanks for simplifying the evolution of CPU/memory architecture.
cmeadows, because you aren't using the same type of chip, it is no longer symmetric.
PIC10F is that 6 pin MCU Jack alluded to...
Great presentation
Thanks for a very informative session.
Great info...Thanks
tomfeliz - VMWare is working on that problem
yes, i've used multiple micros to replace hardware, now we can do this with multicore and virtual hardware.
Thank you Jack, great presentation.
Thank you Alex as well.
so bigger is not always better when it comes to smp design?
Jack, this is an excellent presentation. Complex issues in plain English isnt easy, and you did it. Excellent.
Wouldn't it make sense, in appropriate smaller embedded applications, to use multicore 8-bit CPUs rather than 16-bit or 32-bit multicore CPUs. If yes, then are such "small" products available? I would presume that most multicore offerings are targeted to the larger applications thereby leaving the small applications out in the cold.
Great session again, thank you!
What about virtualization in embedded systems? Seems like a great way to exploit multiple cores and better partition systems. It's also very energy efficient.
does arm with its different busses for memory, IO etc, minimize this problem?
thanks for a great lecture. I have several of your books. love them
thanks alex and jack. nice presentation.
thanks also to mdsmdsmd for posting the current slide #
I've used multiple PIC10F's to do just what Jack suggests and it has worked out VERY well. Good advice!
If we have multiple cpus, will the codes be independent and interactive? How do we handle the interface between the codes?
Thanks for your session today!
Thank you Jack and Alex. It was a good presentation. Great examples on SMP vs. ASMP and how this applies to embedded systems design.
Good stuff. Thanks again.
Question: If memory slows down data why they keep making faster CPUs when we cannot take a real advantage of their speed?
Performance vs. Power Cost. In implementing a solution of separate single cores vs a multi-core setup, is there a power/heat penalty greater than implementing code into separated cores? Also, if product future is taken into account, how much reliability is there in a company to continue a multicore line vs. traditional single cores?
Jack, thank you for the lecture.
Thanks for another great lecture, Jack
Excellent! Also, thanks for not interrupting him today, Alex. Much better. :)
What would be on our way to believe that the faster memories may one day be cheaper to develop than the slow ones like magnetic hard disks? If that were possible, than the bottleneckness of cache may go away, don't you think?
it appears to me that the bus traffic is the main problem.
Thanks for describing ASMP
I'm an old mechanical engineer who has gotten into microprocessore just a few years ago. This course is showing me that I've got a lot to learn yet. Great presentation! Thanks.
Good presentation, thank you.
Interesting, thank you
thanks for the lecture
Do you have any recomendations for tools to help parallelize applications?
Thanks guys.
I really like this presentation. Thank you .
Very Interesting Thank you.
Great Lecture, Thank you!
Great presentation. Thank You.
Thanks jack. Got sort of understanding..
kloc =
1000 lines of code
Kilo Lines Of Code
KLOC == thousand lines of code
KLOC = Thousands Lines of Code
Very interesting material! Thank you Jack and Alex.
Syakovac - thousand lines of code - KLOC
Thanks for the SMP vs AMP explanations
A ton of info to digest here. Thanks, jack.
I was having computer problems at the beginning. What does KLOC mean?
the extreme multicore scenarios that you describe - are they really applicable to embedded design? the problems are (usually) not that large... if you trying to solve really large problems with this approach - isn't it an indicator that you're trying to do something wrong?
******* SLIDE 36 ******** (Last Slide) **********
Thanks Jack, you are giving me responses to a problem I didn't expect to solve in this session!
thats the way our eyes work also
Jack, as the multicore increases, don't we just need to use partition again, so we can divide and conquer?
What are the factors to decide the size/type of memory that build with processor? Where/how to handle to inter-communocation/synchronization between multicores/processors?
nice thing about multicore is virrtual hardware devices.
I guess I am late and wrong then!:)
Jack, all these CPU "improvements" make the CPU performance very non-deterministic. Any suggestions to restore determinism?
Jack, is any body already using "systems identification" to allocate cpu allocation in multicore OS?
Anyone ever see this movie (it says alot about similar to this conversation)
The First $20 Million Is Always the Hardest (2002)
having the system always "working" helps system verification tremendously, also.
Luiz, this estimation is the project manager's job.
and SW guys are usually wrong
LOL so true! HW guys are always late!!
Jack, but "wild guesses" will be completely different depending on knowledge and experience. So, how do you hire peole who, in a large project, will be "wild guessers"? :o)
that's why concept and feasability stage is very important
Welcome to the scrum development methodology: a system that always works with increments of new functionality added in descending order of priority. It works great!
While having multiple components / micocontrollers will help break down a large and complex project into smaller, and more manageable, pieces, the addition of more components also increases the complexity of the PCB layout, an additional components in the JTAG scan chain, additional configuration management of the firmware for multiple micro's, etc. That being said, I still agree with this technique of adding additional "brain dead" processors for managing the project complexity.
which slide
But if you use the principles shown in the retro-encabulator, you'll be in good shape
also an example of bad management
what about test of the radar before mounting on a tank or hooking it up to guns
Good, Fast, Cheap - Choose any two
fast, good, cheap. Choose two.
MultiProcessors: We must remember to handle synchronicity in many cases, i.e. shaft angle at this moment in time.
adding more programmable components in a circuit means also more production time.
how do you address IPR issues with code reuse (code steal - in your slide 11)?
do you mean is better to add additional component so as to reduce coding for the microcontroller
ants do this well, take a huge job and break it down to small manageable tasks
But there are limits to that, particularly if both processors need to use the System Bus.
So many electrical and software engineers try to inpress with complex code rather than impress with clean and robust functionallity and complete desriptions.
it's the KISS principle...
slide 8
OK, so now I'm viewing the slides on my work desktop PC and listening to the audio on my phone, so yes, it is clearly my company now blocking the audio. This is something new since the Basic MCU class a week and a half ago. I mention this since others may be able to use the same workaround.
Divide and Conquer? This is very good information, Jack.
It would be interesting to see if there is any loss in productivity from partitioning code when using a multi-processor chip (aka Propeller) vs. multiple microcontrollers?
or label you varibles correctly
isum ?
Audio is choppy
Devide and Conquer?
@FrankBishop: No kidding! And the project management becomes an issue, also.
Audio is still weak. For tomorrow, maybe Jack can explore the microphone input settings. In most recent versions if Windows one can adjust the mic input level, and even over-drive it with some settings in the sound control panel.
someone knows how to interpret the graphs (@FrankBishop) ;)
I agree audio is worse today
Audio is worse
Is this the number of lines of code that are correct and don't need to be rewritten, or are these lines of code that may also get rewritten?
Productivity really drops when you go from 1 developer to
more than one
Hi Jack and Alex!
Still no audio, just like yesterday.
Hello everybody!
if there's no audio, it's cause your company is blocking live streams. The other thing to try is refreshing your browser but if that doesn't work, you're blocked.
Try FireFox, you'll have no audio issues..
for audio try F5 (refresh your page)
hi all,
Audio is fine here.
No audio here either. No widget to display audio controls.
His sound is just fine for me.
good day all
today audio sound is a little bit un-clear.
OK login again to quit audio loop, is OK now.
no audio
OK, audio is working well today. Let's go!
No audio.
Hi all
Yes, load and clear
No looping here
hello Jack
audio is loud and clear (as usual)
does anyone else hear the audio intro looping?
and it begins
Hello everyone!
audio started now
Hello everybody
We need the Powerpoint Slide switches to make a noise, that way we know when the presenter is switching slides. Also, why no PDF slides???
Has the audio started?
The human brain takes time to process as well.
looking forward to it... sounds really interesting
hello gang...
Hello all
Ah another enjoyable 45minutes...
hi everybody
oh, BTW: why does nobody say RTOS for 1µs or RTOS for 1 ms? If I understand things correctly, _nothing_ can be guaranteed to be a RTOS for every interval. So RTOS only makes sense with a qualifie
Most RTOSes let you set the time base - the tic interrupt rate. 1 usec is too fast as the context switch time will swamp the CPU. Typ numbers are s few hundred usec to 10 msec or so.
could we say "near real time" or "close enough for the application"? for RTOS
greetings all
oh, BTW: why does nobody say RTOS for 1µs or RTOS for 1 ms? If I understand things correctly, _nothing_ can be guaranteed to be a RTOS for every interval. So RTOS only makes sense with a qualifier.
use a semaphore, mutex or an ecb/queue construct
jack21: Still, in between the time where I see that in_use is free, and the time I get to setting it, another task could step in and take the resource away. If, in an RTOS, there are other tasks running.
You're right! And that's really the point of the slide. This is bad code that looks seductively correct.
Jack, I've been reading your articles for years. It's an honor to be in this seminar with you.
hello all, ready for a great session.
Hi everyone.
how do you wait for a resource to become free again? I understand the handshake problem on slide 13, but I can't see a way around it right now. Or is the answer going to be "don't wait, have somebody tell you?
This is a multitasking system, so some other task is executing concurrently, and will drop the in_use flag.
cnorton, as long as youre on this page, you're logged in and should get credit.

Gun measures that make sense
Immediately after the Newtown massacre, the National Rifle Association originally made a plea for our legislators not to rush to any hasty conclusions before considering the passage of any gun safety legislation. Within a week they came out with their recommendations.
Im not sure how they arrived at their magical thinking, but their response of arming teachers and putting armed guards in all schools was less than helpful. Their statement disregarded all evidence to the contrary; totally denying the fact that due to our glut of firearms, the United States has by far the highest homicide and suicide rate due to gun violence (more than 30,000 deaths annually) than any other civilized country in the world with reasonable gun safety laws. Statistics also show that schools are actually very safe environs, with far more gun fatalities on the streets of our cities and in our own homes. We would have a greater impact in decreasing gun fatalities by having armed guards assigned to our homes.
Unfortunately, the White House is considering making federal dollars available to schools that want to hire police officers. With all our concerns over our national debt, this would be a huge financial mistake for very little, if any, real security gains. If a local community feels that it is necessary, it should vote to fund it; this should not be a responsibility of the federal government. Send email to your representative and senators asking them to, at the very least:
Ban assault weapons and high-capacity ammunition magazines.
Require a universal criminal background check for every gun sold in America.
Make gun trafficking a federal crime, with real penalties for straw purchasers (those who arm criminals).
Where are my Republican and Libertarian friends to help prevent our fellow Democrats from taxing and spending?
