Father of the Bride Speech at Daughter's Wedding

As the summer wedding season gets going, as the proud father of the bride, you may have to deliver a brief welcome speech at the reception. If so, here's my "father of the bride" speech for you to use as an example. This one is also an exception to the 3-minute rule for my NBTMV videos -- weighing in at almost 6 minutes, but you can't blame me for being long-winded; after all, this is my daughter's wedding and the first one at that!
Below is the speech as I had prepared it, but I spoke from memory, so the video does not match exactly, but it's always helpful to prepare (notice how short it is in print, yet it took almost 6 minutes to deliver the speech):

Good evening everyone. On behalf of my wife Leha and our family, we’d like to welcome friends and relatives of both families who are gathered here today to celebrate the marriage of Emily and Anran.
Thank you for taking time from your busy lives to join us on this evening, in some cases traveling quite a distance to be here. We hope you’ll enjoy the rest of the evening and remember this day fondly as we surely would.
I feel so proud today to be standing here as the father of the bride as she is looking beautiful with the man of her dream.
I remember as if it was only yesterday... when Emily was 4, she started to play children’s songs by ear on our piano and that’s when we decided to give her piano lessons when she turned 5.
The other thing I remember is how one day she announced that she wants to learn the violin when she was 9 and in elementary school. Despite discouragement from my wife who thinks the violin is much harder to learn than the piano, Emily’s progress was so impressive within 6 months of learning the violin that her mother was convinced that Emily would be able to play the violin after all. I remember her having violin lessons with Jody Gatwood and later taking her to Juilliard in NY city for violin lessons in her senior year. After year’s of chauffeuring to violin lessons and orchestra rehearsals, we were so happy when she got her driver’s license and could drive herself to her fellowship with the National Symphony Orchestra at the Kennedy Center. Emily is so good at everything -- from handicraft to cooking to math and science -- she got perfect score in math in both the SAT & GRE -- she could have been anything, but she chose music and the violin because she loves it.
You know, how some parents think no one is good enough for their daughter, it’s quite the opposite for us; we think Anran is great for Emily. He’s very considerate and thoughtful-- not to mention, extremely smart.

Emily and Anran have been friends since middle school and became best friends in college. With their love and friendship Emily and Anran can face anything that life may throw at them.

Traditionally, at this point, I should offer some advice on marriage, but you two have known each other and been together now for quite some time, so you don’t really need much advice on that front. The only practical advice I can think of is -- cook for the entire week during the weekend, live like you’re still a graduate student, and take vacations each year. That should see you through a long and happy married life.

Before I close, may I propose a toast to the most important couple tonight... if you’d please join me...

Ladies and Gentlemen, Emily and Anran -- here’s to a long and happy marriage!

Visiting Lisbon, Portugal

We visited Lisbon, Portugal for a week in late February 2012 and enjoyed it very much. We rented an apartment and explored the city on our own. As usual, I started by buying a copy of Lisbon travel guide to figure out the layout of the city and then searched for apartments on VRBO.com near Rossio, which is one of the main areas of the city.

We found an apartment called Casa Travessa that was located a short walk up the hill near Rossio, the busy central plaza. The apartment served as a very convenient base from which to explore the great city of Lisbon. When we arrived on Saturday, we were greeted by Maria, a friend of the owners, Jordan and Deb Kleber, who happened to be away in Italy that week. Maria gave us the key and  took us on a very helpful tour of the neighborhood --  how to get down to Rossio, the restaurant street, metro station, Rossio train station, and tram stops, etc. We found a welcome basket with bread, cheese, fruits, and vinho verde (green wine) to get us started. We shopped in Pingo Doce for milk, bread etc for breakfast and light meals and the apartment served as a great base for our daily excursions. Jordan and Deb had also sent us helpful information about the neighborhood and restaurants.

Before I forget, here’s some helpful advice -- get a €5 "7 Colinas" card from the Casa da Sorte store on Rossio that's good for 24 hours of unlimited tram and metro rides (and refill it every morning, the first time, you’ll pay €0.50 extra for the card itself). If possible, go to Belém and museums on Sunday when it's free. If you plan to go to Sintra, check the days when the Pena Palace and National Palace are open.

We did all the usual sightseeing in Lisbon  -- on Sunday morning, after buying the “7 Colinas” card, we took Tram 15E to Belém to see the Belém tower, National Coach Museum, San Jeronimo monastery), had lunch at Os Jeronimos restaurant and coffee plus the famous Pasteis de Belém (called Pasteis de Nata elsewhere), and then took the metro to see the Gulbenkian musueum in the afternoon. We rode the famous Tram 28E many times from Martim Moniz park nearby all the way through Alfama and Bairro Alto. We got off the Tram 28E to see Castelo San Jorge (the castle), Miradoro St Luzia, and Sé cathedral. We also took the Elevador Gloria funicular up to Chiado, to see the city from up there and also taste port wine at Solar do Vinho do Porto.  One day we took metro to the Oriente station and visited Parque das Naciones. We spent nearly each afternoon walking the plaza in Rossio, then down Rua Augusta pedestrian street to Praca Comercio and back. We had coffee and Pasteis de Nata each afternoon. We liked the area around Rossio a lot.

We took a day trip to Sintra by train from the Rossio train station and another half-day trip by train to Cascais (from the Cais do Sodré station) to enjoy the beach. In Sintra we saw the Pena palace and walked around the city. We also had a good lunch at the GSpot Gastronomia restaurant near Sintra train station.

There are lots of good restaurants in Lisbon. We ate meals at the Bom Jardim (slowly roasted chicken with piri piri sauce) and Cafe Tighelina nearby, and took the ferry across Rio Tejo to Cacilhas for a seafood lunch at Farol restaurant (shrimp in garlic sauce, Bacalhau à Farol platter -- bacalhau is salted cod, very popular in Portugal). We also ate at a small restaurant near the Castle called Claras em Castelo that was quite good.

Cybersecurity is hard, we need some assist

Cybersecurity is so much harder than physical security! In physical security, you have a well-defined physical perimeter -- your doors, windows, gates etc -- to watch and protect, but in cybersecurity the perimeter is not well-defined. Think of cybersecurity for a typical home or business -- you usually have a box -- the “router,” perhaps a wireless one -- that lets you connect your network of PCs and other devices to the Internet via your Internet Service Provider. Although there is a single physical connection to the Internet, the software applications in your PCs and devices are making lots of network connections. If you think of each of these as a door, it’s like trying to watch over and protect thousands of doors at once and, on top of that, you need to check the packets of information that are coming in and going out of these “doors” -- like checking each visitor to a building, only the number of visitors is in the billions! To make matters worse, the software applications -- think of Web browsers, Office suite, PDF reader, etc have their own weaknesses and could serve as gateways through which bad guys get access to your information... so that’s even more “doors” to protect. Anyway, you get the idea -- compared to physical security, cybersecurity is too difficult for us to tackle in a routine manner.

Does that mean we do nothing about cybersecurity? Of course not! We already try to do our best with antivirus and firewalls etc, but to keep up with the ever-changing number and types of “doors” that we have to watch over, we need some assist from the information security companies.

First, we need a way to monitor the status of cybersecurity, similar to the way we have guards monitoring doors, fences, and gates through video cameras etc. Only in cybersecurity, someone needs to build a simple dashboard to show us how well our defenses are working against the torrent of potential malicious packets coming through the cyber “doors” to our network.

Second, someone needs to build a consumer “cybersecurity appliance” -- I envision a box that sits between that router and the rest of your network, a box that watches over all the network connections and does whatever is needed to keep our internal network safe. Come to think of it, the cybersecurity appliance can both monitor cybersecurity and provide protection.

I hope someone takes up the challenge and builds us a “cybersecurity appliance” someday soon.

Assessing impact of using facial recognition technology

In a previous video I talked about the importance of assessing the impact of technology before adopting it. Today I want to talk to you about the impact of increased use of facial recognition technology. You may have already heard about the use of facial recognition technology to detect the mix of male and female customers at bars. Facial recognition technology is also used to identify people on the street or in a crowd.

Facial recognition is what is known as biometrics, which is identification of people from some features of their body such as fingerprint, iris pattern, or facial characteristics. No matter what biometrics we pick, if you stop and think about it for a moment, you would realize that your fingerprint or facial image does not come with your name stamped on it. Rather, somewhere in a computer system your facial image and your name are linked together. That linkage between your name and your facial image must be correct to begin with and the information must be stored securely.

Additionally, facial recognition systems are not error-free and there is a potential for misidentification.

So, as much as facial recognition is useful, it is not error-free. Therefore, you need some protection when the facial recognition technology misidentifies you as someone else. You need some way of correcting the mistake.

There is also the potential of someone trying to fool a facial recognition system by presenting, for example, a photograph or a video of you as your face. Something has to be done to detect such misuse and not accept a photograph as substitute for a face. It’s not easy to overcome this problem because facial recognition system identifies people from photographs or videos.

This means that if you are using facial recognition technology to identify customers or perhaps suspected criminals, you have to make sure that appropriate security precautions are in place to protect the linkage between a person’s facial image and their identity information and that the information is correct in the first place. You must also provide some sort of recourse when someone is misidentified.

How to lose weight - a story to motivate you

If you want to lose weight, here's a story to help and motivate you.

I always knew that good food with fewer calories and exercise are important to manage your weight, but when he was young did not follow this advice. My diet included lots of rice and very little exercise. So, over many years, bit by bit, I gained weight. When I was 44, my weight was over 200 pounds. Around this time, I had a stroke of good luck. My youngest daughter wanted to run in a 5K race and asked me to run with her. I agreed and started running on the treadmill to get ready for the race. Soon I was running five kilometers in less than 30 minutes ans was so proud that I could run five kilometers!

At the same time, I saw a TV show where a doctor discussed how to improve your diet. He said it is important to eat plenty of vegetables, fish and white meat. I changed my diet after watching that program. I substituted rice in my diet with green leafy vegetables. For breakfast and lunch I ate vegetable and chicken (or fish) soup. For dinner, I ate salads with fish and grilled salmon (but without any dressing). But I made sure that I ate the same volume of food as before, so I was not hungry even though I was eating salads instead of rice. By the way, I also started drinking black tea instead of coffee with milk and sugar.

So, overall, I made two changes at the same time: started doing more exercises and reduced the calorie intake (because the veggies had less calories than rice). The body responded by losing weight. Within a few weeks I lost over 30 pounds. I really liked this because I could see the results very soon. I could also continue the program of diet and exercise because I was not hungry. I really felt better than I ever felt before.

Even though I have been continuing this program since 2003, my weight has gone up some. Over the past eight years, I have gained weight about 8 pounds. But it’s still a great way to lose weight and manage your health. When I think why the weight has gone up despite maintaining about the same diet and exercise, all I can think is that the body has a mind of its own and it fights your attempts to lose weight.

If you are thinking about trying to lose weight, I recommend that you make two changes in your life: start an exercise program and change your diet by replacing carbohydrates with veggies. Stop eating too much rice or pasta and eat a lot of salads with fish (or chicken) but skip the dressing .Remember that to succeed you should eat the same amount of food as you ate before making these changes because it is very important to not be hungry. Good luck!

Cómo perder peso

Si quieres perder el peso, aquí está una historia para ayudarte y motivarte.

Siempre sabía que buena alimentación con menos calorias y ejercicios eran importantes para manejar su peso, pero cuando era joven no seguía este consejo. Comía mucho arroz y hacía poco ejercicios. Así que, hace muchos años, poco a poco, me gané peso. Cuando tenía 44 años, pesaba más de 200 libras. Al rededor de este tiempo, fue una buena suerte que mi hija menor queria correr en una carrera de cinco kilometros y me pidió aue la acompañara. Estaba de acuerdo a correr con mi hija y empecé a correr en la cinta para estar listo. Muy pronto estaba corriendo cinco kilometros en menos que 30 minutos. Estaba orgulloso de poder correr bastante rapído como eso.

Al mismo tiempo, ví un programa de televisión donde un doctor discutió comó mejorar su dieta. Se dijo que es importante para comer muchas verduras, pescado, y carne blanco. Decidí cambiar mi dieta despues de ver ese programa. Sustituí arroz in mi dieta con verduras de hoja verde. Para el desayuno y para el almuerzo comía sopa de verduras y pollo. Para la cena, comía las verduras con pescado como el salmón a la parilla. Es como una ensalada sin aderoso. La comida tenía el mismo volumen como antes de cambiar la dieta. Asi que no tenía hambre a pesar de que comía verduras en lugar de arroz.

Así que hice dos cambios al mismo tiempo, hacer mas ejercicios y reducir las calorias de comidas. El cuerpo respondió con la perdida de peso. En unas semanas perdí más de 30 libras. Me gustó mucho porque pude ver los resultados en poco tiempo. Podía continuar el programa de dieta y ejercicio porque no tenía hambre. De verdad me sentía mejor que antes.

Aunque continuaba esta programa desde 2003 el peso se sube un poco. En los últimos ocho años el peso aumentó 7 u 8 libras. Sin embargo este ha sido un buen método para perder peso y manejar tu salud. Cuando pienso en porque el peso sube a pesar de las mismas dietas y ejercicios, creo que el cuerpo tiene una mente propia y lucha contra de bajar el peso.

Todavia si no trata de manejar el peso, te recomiendo que hagas dos cambios en tu vida: comienza un programa de ejercicio y al mismo tiempo cambia tu dieta reduciendo los carbohidratos. Deja de comer demasiado arroz o tortillas y come mucho ensaladas con pescado (o pollo) pero sin aderezo. Recuerda que para tener éxito debes comer el mismo volumen de comida que comías antes de hacer estos cambios porque es muy importante no tener hambre.

NBTMV on using biometric technologies to identify people

Biometric technologies use specific features of your body such as fingerprint, facial image, iris pattern, or even the geometry of your hand, to identify you.  Assessing the impact of using biometrics depend on the exact type of use. If your laptop has a fingerprint reader where you swipe your finger to log in, then all we may need to worry about is the possibility that the system somehow could not match your fingerprint with what was previously stored in the system, in which case, there should be some alternate method for logging into the laptop.

On the other hand, if biometric technology such as facial recognition is used to identify a person from among millions in a database, then we have to think about many more things.

For  starters, you know that your fingerprint or facial image or iris pattern do not come with your name stamped on the it, which means that some computer system has to store your identifying information with your biometric features.  That association must be correct when it’s initially stored (meaning that your biometrics are linked to your identifying information) and the information must be securely stored and maintained.

Next, we have to consider the potential of errors in the system that compares and matches your biometric features such as your fingerprint or your facial image with information stored in a database. There is a possibility of misidentification where someone else’s biometric may be identified as yours or vice versa. This means that we need to provide some redress mechanism for anyone who is misidentified. This is especially important if the biometric is being used to look for a criminal, for example, and you are mistakenly tagged as that criminal.

Another potential problem is when someone intentionally tries to fool the system by presenting, for example, a photograph of you as that your facial image.

These are among some of the issues that we need to consider when assessing the impact of using biometric technologies to identify people.
