Daemon

I just finished reading Daemon by Daniel Suarez, a story about a computer daemon (automatically running program) that wreaks havoc in the world. The book has a similar theme to Neal Stephenson’s Reamde: massively multi person role playing computer games that bleed over into the real world. Suarez’s story is not as wide ranging as Stephenson’s, and he focuses more on the video game aspects of the story.

The other major difference is that in Reamde humans use computers to interact with each other while in Daemon, as you could guess from the title, one of the main characters is a computer program – a very powerful one. Since just about everything today has a computer chip in it and is networked, it is scary to think about something that can communicate directly with the “inanimate” devices around you and get them to do its bidding. Suarez has some imaginative, and sometimes horrific, ways this can happen.

This story has lots of action and some interesting concepts to think about, but none of the characters have much depth and at the end you do not feel you know a lot about any of them. The daemon is a computer program, so you would not expect to know much about its motivation and character. It reveals its reason for being several times during the story, but always with the same few sentences. The human characters are the same. They are very stereotypical, and we never find out much about them.

If the characters had more depth this would be an A+ story. It is a fast-paced thriller with some interesting concepts to think about, so I still recommend it. In fact, as soon as I finished it I ordered its sequel, Freedom(TM).

Justice Served

I posted earlier about a break-in at my home over the holidays. A lot of electronics and flying gear were stolen, and I figured they were gone forever.

However, I got a call from a detective at the Fort Worth police department over the weekend, and they have recovered some of my stolen items. They arrested two people on suspicion of burglary, and among the items they recovered from the suspects was a Swiss Gear briefcase with some USB flash drives in it. One of the drives had data from my flying club on it, so the detective called a flying club member listed in the one of the files to see if they knew anything about this. The person he called is no longer in the club, but he referred the detective to the current club president, who knew all about my burglarly and quickly figured out whose items the police had recovered.

The detective called me and asked if I was missing a Swiss Gear briefcase and laptop, and if I was in the Six 4 A Six flying club. Of course, I was excited to hear they had recovered at least some of my stolen property. Then he began to describe the stolen laptop, a Sony Vaio asking for a login password for someone named Daugherty. Oops, that’s not me, and my stolen laptop was a Dell. Looks like they stuck someone else’s laptop in my bag.

The good news is I can go claim my property after the police finish cataloging the recovered items, maybe as soon as today. From the detective’s descriptions over the phone it sounds like they found my briefcase with at least some of the items contained in it and my flight bag with the headsets that were in it. They may have more of my property, but I will have to visually inspect it to see what they have. No mention of the two computers, television and other items that were stolen.

The other good news is that two people have been arrested for this. Don’t know if they were the ones that broke into my house or just intermediaries trying to sell stolen property, but either way I am glad they caught someone involved in this crime. Who knows, maybe now that they have someone in custody they can use them to track down more of the property.

The Best Laid Plans…

Flying from Fort Worth to Texas A&M for a basketball game combines two things I really enjoy: flying and watching Aggie sports. The weather last weekend was beautiful, one of the club’s planes was available, and A&M was playing Oklahoma State in basketball – an unbeatable combination. I invited a friend from work to go along and looked forward to a fun day.

We got to the airport around 10am and began preflighting the Cherokee Six we would fly that day.

Cherokee Six

N33354

Everything looked good except all the tires needed air. The friendly linemen at Atlantic Aviation quickly took care of that problem, and we were ready to go. We got in the plane and began running through the checklist: seat belts, avionics master off, prop full, mixture full lean, throttle open 1/4 inch, beacon on, master switch on, fuel pump on, advance mixture control… Wait a minute. Why won’t the mixture control budge?

Try wiggling the mixture control a little. Nope. Nothing. Shut everything down. Try the mixture control again. Still nothing. Peer inside the throttle quadrant to see if something is jammed in there. Nothing. Take off the cowl and look inside the engine compartment. Nothing there either. We spent about an hour looking for the problem and could never find it, so we were not taking the Six on this trip.

The other club plane, a Cessna Cardinal RG. was not available because two other club members were going to work on installing new plastic trim on its interior that day. They arrived at the airport as we were working on the stuck mixture on the Six, and when they saw we were not going to be able to take the Six they offered to postpone their work and let us take the Cardinal. Very generous.

N8084B

The Cardinal

Soon we were on our way, still with plenty of time to have lunch with my daughter in College Station and make the basketball game on time. Things were looking up!

The situation improved even more once we got up to cruising altitude. We had a 20 knot tailwind. That gave us a speed over the ground of about 150 knots (~170 mph). This is fun! As a bonus, it was a crystal clear day and the air was smooth.

Dallas

Dallas and Joe Pool Lake from about 50 miles away.

The flight down to College Station went well, and we were soon having lunch at Los Cucos  Cafe. Then it was straight to Reed Arena for the basketball game. We sat down right before the national anthem started, and then watched an Aggie Big 12 win.

TAMU vs OSU

The game stayed pretty close most of the way.

After the game, we went straight to the airport to prepare for the flight home. Preflight, engine start and the taxi down to the end of runway 34 went fine. However, during our pre-takeoff engine run up, we discovered the left magneto was dead. As in, when you moved the ignition switch to the left magneto position, the engine would immediately quit firing as if the mixture had been pulled to the cut off position. I did it several times to make sure I was not imagining the symptoms. It was repeatable, so it was time to go back to the terminal and look for a mechanic.

By this time, it was getting fairly late on a Saturday evening, and there were no mechanics around. Great. Stuck away from home with a broken airplane.

Luckily, my daughter was nice enough to lend us her car, so we could drive home that evening. It’s a 3 hour drive, compared to a 1 hour flight. Not unbearable, but not as fun as flying. The only compensation was the we got to stop at Czech Stop in West for kolaches on the way home. Can’t do that in the airplane.

I drove back to College Station on Sunday to get the plane to a mechanic first thing Monday morning. He checked the ignition switch, ground wire, and ignition wiring harness for problems, and they all checked out OK. That points toward the problem being the magneto itself, so it has been sent out for testing.

That is where this story stands. The magneto is on its way to a shop for testing. I will post an update when I find out what the problem was.

And even with all the problems (I left out the part where I got a speeding ticket on the drive home) it was still a fun day. Just not quite what I expected when the day began.

Lake Worth Rising

The Dallas-Fort Worth area has received 4.27 inches of rain in the last 24 hours. That is a record 24-hour rainfall for the month of January, and it has caused record flooding as well. Lake Worth has been a few feet low all year, but it rose over 2 feet in the last 24 hours and it is still rising. At least the rate of increase in lake level is slowing as it approaches normal.

Lake Worth levels

Lake Worth level data from the U.S. Geological Survey

I was out of town yesterday, recruiting at the Texas A&M Engineering Career Fair, and did not arrive home until late in the evening so while I knew it was raining I did not realize it had been that much and that the lake level was rising.

So it was a bit of  a surprise when I woke up this morning and looked out my back window to see — cormorants! Not just cormorants, but thousands of cormorants.

cormorants

Thousands of cormorants gather on Lake Worth

The picture only shows about half the cormorants that were on the lake. They seemed agitated and were flying in circles and swimming rapidly in random directions.

Then I noticed the lake level. You can see in the picture how the water has risen almost up to the bottom of the boat in its lift and how the jet ski is floating above its ramp. (It’s tied on the front, so it is not going anywhere.) It was still raining pretty hard and obvious that the lake was going to continue to rise so I immediately ran out and raised the boat farther above the water. The boat is not tied to its lift. It uses gravity to stay there, so if the water rose enough to float it off the lift it would drift away.

That taken care of, I left for work. However, I did not want to leave the jet ski tethered and floating loose for too long since it could bang against the ramp supports and get damaged if it started floating completely clear of the ramp. So when I got home today, I put on my wetsuit (glad it still fits!), went in the water, and pushed the jet ski farther up the ramp where it would be more secure.

Wet suit

Wet suits are good for skiing or for just working in the cold water.

The lake temperature is about 51 degrees Farenheit, so the wet suit made being in the water a lot more comfortable. It only took a few minutes to get the jet ski adjusted. Then it was time to come back in the house and take a hot shower.

If the lake continues to rise the jet ski ramp could become completely submerged. I don’t think it will rise enough to do that, but now that lake levels are back to normal I need to move the jet ski ramp closer to shore. That is a multiple-person job. It will have to wait until the water warms up in the spring. In the meantime, the jet ski probably needs to come off the ramp and go on its trailer, safe and dry on shore. Sounds like a good job for this weekend.

IFR Flight – College Station to Fort Worth

Flight track from College Station to Fort Worth

I flew from Easterwood airport in College Station, Texas to Meacham airport in Fort Worth, Texas yesterday. There was a fairly low overcast ceiling at both airports at the time I wanted to leave, so an instrument flight rules (IFR) flight was in order. In general, I don’t fly IFR from College Station back to Fort Worth if I don’t have to. Fort Worth to College Station is OK, but not the other direction.

That’s because I never get a direct routing coming back into DFW. In order to fit into the busy traffic flow into the DFW area, I always get routed off to the east of Dallas and then northwest into Meacham. This is called the DODJE3 arrival, NAVYS transition. It usually adds 10-15 minutes to the flight, which is why I usually try to avoid it. Yesterday there was a pretty good westerly wind at my cruising altitude of 6,000 feet with even stronger winds up higher. That meant this routing added an extra 20 minutes onto the flight.

I could have waited another hour for the ceiling to lift, but there was another consideration. There was a cold front approaching, and the winds at Meacham were forecast to reach 35 knots with gusts to 45 knots later in the day. I wanted to make sure I was back and safe on the ground before that happened.

So, IFR it was. The ceiling at Easterwood had lifted to 800 feet by the time I departed. The clearance I got was KCLL V194 NAVYS DODJE3 KFTW. In English that means to takeoff from Easterwood, intercept airway Victor 194, follow Victor 194 to the NAVYS intersection, and then follow the instructions for the DODJE3 arrival to get the rest of the way to Meacham. I took off from runway 16 at Easterwood with the instruction to fly a heading of 190 after takeoff.

After takeoff, the control tower handed me off to Houston departure. The controller in Houston gave me a choice of a left turn or right turn to intercept V194, and I chose a right turn, so she gave me a right turn to a heading of 020. I chose a right turn because I figured that was the most direct way to get to V194 (the shaded line running north-northwest to the left of my initial track and eventually merging with it), but a heading of 020 was heading me slightly away from V194 and not on a course to intercept it.

I flew that direction for  a couple of minutes then asked the controller to verify she really wanted me on a heading of 020. After a few seconds of silence she came on the radio laughing, saying she was used to vectoring jets with a larger turn radius and they normally end up to the left of V194, not on the right like me. She gave me a more northerly course to intercept V194, and we laughed again about my plane being so slow.

About a third of the way through the trip, I switched over to Fort Worth Center and the controller there was able to give me a shortcut, which was basically to fly directly to the endpoint of the DODJE3 arrival instead of having to follow all its turns.

By the time I got to Meacham the skies were clear, so I flew a visual approach to runway 16 . There was already a pretty good crosswind blowing at Meacham, so the landing was a good test of crosswind technique. The Cessna Cardinal RG handles crosswinds well, so it was no problem.

I am glad I got home when I did. As I was leaving the airport in my car, I could see a large dust cloud off to the west, and by the time I got home those 45 knot winds had arrived too – about an hour earlier than forecast. Landing in those winds would have been more of a skills test than I really want to take.

Reamde

I read the new Neal Stephenson novel, Reamde, over the holidays. It is less intricate than other recent Stephenson novels and more action-oriented. In other words, it is more Snow Crash than System of the World.

What caught my eye immediately about the book is that one of the protagonists is a CFD engineer. OK, an athletic, female, Eritrean-immigrant CFD engineer, as if just being a CFD engineer caught up in a wild adventure is not exotic enough. Since that is the field I work in, that hooked me immediately, and I enjoyed the whole story.

This is what real CFD engineers look like. (Image courtesy of Pointwise, Inc.)

Even though this book is not as complex as most Neal Stephenson stories, it still manages to interweave several story lines involving professional Chinese video gamers, drug smugglers, Idaho survivalists, Filipino prostitution rings, Russian mafia, al Qaeda terrorists, and a CFD engineer into a fast-paced and coherent adventure. Don’t worry, no CFD computations are performed in the course of this story. That would have killed the pacing and excitement right away. There is plenty of action and lots of interesting concepts to think about.

One of the intriguing ideas to me was that people can make money off their characters in multi-player, online, role-playing games. (Think World of Warcraft.) I am not into role-playing games, but apparently people already do this. In the novel, Chinese video gamers work at building up their characters and collecting weapons and virtual wealth they can then sell to other video game players for real money. The character’s weapons, power, and wealth are transferred within the game, and real money changes hands outside the game. It makes sense in the story, so maybe this is something that already happens frequently in real life. If not, I bet it becomes a trend before too long.

I put Reamde right up there with Cryptonomicon as one of my favorite Neal Stephenson novels. If you like techno-thrillers, you might like it too.

Webinar or live meeting?

I attended two aviation-related events the past two days. On Tuesday evening I attended a webinar, Abnormal Procedures for General Aviation, hosted by the FAA FAAST team and conducted by flight instructor Gene Benson. Tonight (Wednesday), I attended a seminar at a local hotel, Wanted: Alive! Reining in the Fatal Accident Rate, sponsored by the Aircraft Owners and Pilots Association’s Air Safety Institute.

Both events were interesting and informative. Their subjects were related. The webinar was geared toward thinking ahead of time about unusual situations you might encounter while flying, like an abnormally high oil temperature gauge reading, and what steps you would take to address them before they develop into something more serious. The local seminar outlined several actual accident scenarios and tried to get you into the thought processes of the pilot’s involved so you might be able to prevent similar mistakes in your own thinking.

The different experience in the two formats was also interesting. The online webinar was nice because I did not have to leave my house. I sat in a comfy chair with a drink in my hand and watched the presentation. Gene Benson made good use of the online polling capabilities of GoToWebinar to outline several abnormal situations and then poll attendees on which of several actions they would take. There was one technical difficulty at the end of the webinar that caused him to not be able to tell who wanted to ask questions, but several people were still able to ask questions or make comments.

The in-person seminar was only 10 minutes away from my house, so it was still convenient, but not like sitting in my own house. The presentation format was similar to the webinar, except instead of multiple choice options for the scenarios the presenter left it open ended and let audience members provide there own actions. There was one technical difficulty caused by the presenter forgetting to plug in the power cord for his laptop, but that only caused a couple minutes delay while he grabbed the cord from his briefcase and attached it. Another advantage of the in-person seminar is that he was able to give away some hats and books as door prizes.

I can’t say one format was better than the other. I liked the convenience of the webinar, and I thought more about the scenarios in the webinar because there were no distractions. (A lot of the answers in the seminar were pretty far out in left field.) On the other hand, at the seminar I sat next to a friend and we were able to exchange ideas about the presentation as it was going on. Also, it was nice to see the other hundred or so people at the seminar to get an idea of the type of people interested in this. There were over 800 people attending the webinar, but I have no idea who any of them were.

The bottom line is both formats worked well. The quality of the presentation content plus the style of the presenter are much more important. Both of these events had high quality content and good presenters, so both were winners.

And if you are wondering why there are so many general aviation safety seminars going on, the general aviation accident rate is about 40 times that of the airlines. It is bad enough that general aviation safety is on the National Transportation Safety Board most wanted list. Most of the problems are caused by poor decision making by pilots, hence the number of seminars and other events related to general aviation safety.

Customer Service

I went out of town between Christmas and New Year’s and my house was vacant. At some point during that vacancy burglars broke a window in my house, entered, and removed a television, home theater system, iMac computer, Dell Latitude laptop computer, Dell 3100cn color laser printer, AT&T 2Wire DSL modem/wireless router, a pilot’s flight bag containing 2 headsets and a bunch of flight gear, a KitchenAid Mixer, and various other items.

Consequently, I have spent a lot of time lately working with the police, my insurance company, and various companies to replace the stolen items. My experiences in dealing with these various entities have been mixed – for the most part positive, but with one notable negative exception.

First, the positives. The Fort Worth police were prompt in coming to my home even though the break-in was long over by the time I arrived home. The two officers who showed up were courteous and thorough. They took statements from my daughter and me, took fingerprints in several likely locations, and explained the investigative process. Since that initial call I have talked to the detective assigned to the case and to administrative staff to record serial numbers and other information about the stolen items. They have been unfailingly courteous and easy to work with.

My insurance company, USAA, has also been easy to work with. They quickly worked with me to make an inventory of the stolen items, reimbursed me for the depreciated value of the items, and then explained how to get full replacement reimbursement by sending in receipts for purchased replacements. At every step of the the way they have been easy to work with.

Apple and Dell computer have also been easy to work with by helping me  find serial numbers for stolen items and recover stored data. Again, they have been courteous, helpful, and easy to contact.

Lightspeed Aviation and Tina’s Pilot Shop were also easy to work with and helped me register my stolen headsets so they may be recovered if someone tries to sell them.

So what has been the negative part of this experience – aside from the burglary itself? My AT&T DSL modem was attached to my iMac and went out the door with it when the thieves departed the scene. Thinking Internet connectivity was one of the most important things I needed, the first purchase I made was a new DSL modem at the local AT&T store. Unfortunately, the modems were not in stock. Fortunately, they had some in the Fort Worth warehouse, and I could have one shipped directly to my home. I purchased one immediately, and then waited for it to arrive. And waited. And waited. And I am still waiting after two full weeks.

Everything else I needed to replace was ordered after this. Everything else I needed to replace has already arrived.

So where is my AT&T DSL modem? That is one of the unanswerable questions of the universe. I tried calling AT&T. Here is how that process goes:

  1. Call AT&T and get automated system requesting account information.
  2. Enter account information.
  3. Listen to menu of options.
  4. None of the options seem applicable, so pick what seems to be the closest.
  5. No, that was not it, so try something else.
  6. Finally, just stay on the line to talk to a person.
  7. Give the nice person who comes on the line, the same information entered in step 2.
  8. Find out this person cannot help, so they will transfer me to another number where I can get some help.
  9. Begin again at step 1.
  10. Repeat until you eventually give up.

OK, the phone does not work, so let’s go back to the AT&T store where I initially placed the order. Here is how that goes:

  1. Enter name at kiosk to get in line to be helped.
  2. Look at cell phones, tablets and other AT&T products and services for sale for 10 minutes while waiting for help.
  3. Give order information to friendly AT&T service rep who calls my name.
  4. Wait while they go in the back room to check on my order status.
  5. Listen while they explain it is not possible to figure out why a modem in the local warehouse still has not shipped and that it is best just to go home and wait.
  6. Watch as it seems that all AT&T service reps in the store seem to have trouble getting any useful information for customers.
  7. Go home and wait.

Yes, AT&T has been my sole negative experience, but it has been a doozy.   This is not my first experience with AT&T, and it is not my first bad experience with AT&T. In fact, their service has been unfailingly bad in every interaction I have had with them – from the business phone system salesman whose entire sales pitch was “We invented the telephone” to countless time spent waiting on hold or at AT&T stores.

However, I will point out that the service people I have interacted with at AT&T have been unfailingly  courteous and friendly. They have tried to help me, but the systems AT&T has set up make it impossible for anyone to determine anything of use to customers.

Finally, to make this whole situation even more absurd, I have to admit that I own stock in AT&T, thinking it was an undervalued component of the Dow. I now realize how stupid I was to think it was overvalued. I will be selling it tomorrow.

As for my DSL modem, I still have no idea when it will show up, and I do not think it is humanly possible to determine where it is or when it will arrive. (Posted with a modem loaned by a gracious friend.)

Easy Lending Solves Overspending Problem?

Given: Financial markets are troubled by the poor fiscal situation of governments around the world as they are spending much more money than they collect in taxes.

Find: What is the best way to improve financial market performance?

Solution: Obviously, the solution is to make it easier for governments to borrow more money so they do not need to cut back on their spending.

Does this make any sense at all? We are in a repeating pattern where governments should be cutting their spending or increasing their tax revenue to reduce deficits, but instead they keep getting easier access to more borrowed money.

It seems like we are delaying the day of reckoning, and by increasing the amount of money owed we are also making the eventual reckoning much more painful.
