Running MySQL and phpMyAdmin with Docker

2020-09-24T22:02:00.001+02:00

It's so easy.

First, run the MySQL server:

docker run --name mysqldb -e MYSQL_ROOT_PASSWORD=mypasswd -d mysql:latest

Then run the phpMyAdmin server:

docker run --name myadmin -d --link mysqldb:db -p 8080:80 -e MYSQL_ROOT_PASSWORD=mypasswd phpmyadmin:latest

Then open your web browser to http://localhost:8080/ and log in with user root and password mypasswd.

That's it!

Relearning C++

2014-08-20T09:11:00.002+02:00

There's quite a lot of developments in the C++ programming language in recent years, first with the long-awaited C++11, and just this week, the new (surprisingly on-time) C++14. The language has changed quite considerably that it's safe to say, "It's not your grandma's C++ (or C, for that matter)!"

So, I think I'll have to devote some time from now on to learn about new C++ paradigms. I'll be posting about them as I go along.

New Team, New Challenges

2013-03-18T10:34:00.003+01:00

Since the beginning of this year I have moved to a new team at work. In my previous team, while we did have new services (back-end servers) to create, we were more or less in maintenance mode. That is, we get to fix bugs on the existing infrastructure and make incremental improvements, adding new features too (and new bugs) from time to time.

In my new team, however, it's very different. We're creating completely new product, and so we have take care of things that developers in maintenance mode don't even get to think of. We have to interact with operations teams to prepare new hardware, new databases, new network setups, new code repositories, etc.

As it is a new product, we also have lesser inputs from marketing and product definition teams, thus, we have more freedom in implementing our vision for this product. I find this really exciting and empowering.

I can't say much for now (as it's a bit hush-hush), but anyway, this should be a very interesting year!

Here comes the Pi!

2012-12-28T11:22:00.000+01:00

So... Shortly before Christmas, my wife decided to give me a fruity gift. Yeahhhhh... Raspberry Pi!

It should arrive at the end of the year. Yep, the 31st of December 2012. What a way to start the new year!

I'll start posting on my Raspberry Pi adventures next year.

Raspberry Pi

2012-03-01T08:51:00.000+01:00

This is awesome! What am I talking about? Raspberry Pi, an ultra-low-cost computer, about the size of a calling card, that you can buy at only 25USD! And as if that's not awesome enough, they say that the production model is going to be a lot smaller. For now, it runs with Fedora Linux as its operating system, but we can imagine there'll be other OSes soon too.

So... What can I say? Hats off to the ones who developed this tiny pack of awesomeness. Here's a video of a fully working model.

Paris

2011-09-27T17:11:00.002+02:00

It's been a while since my last post on this blog and I felt kinda sad about it. I still don't have much to post, although that doesn't mean that there isn't much going on in my life right now -- quite the contrary!

Anyway, the reason I'm blogging again (and hopefully it'll be more frequent) is because I heard Yael Naim's song, Paris. Actually, I've heard it for some time now but I didn't know the lyrics. A Google search today finally gave me something (from a web forum) that's understandable and readable (not just Hebrew characters). So here it is, Yael Naim's Paris with lyrics:

Paris

Finally!

2011-04-17T23:21:00.001+02:00

I'm so happy with myself today. Why? Well, simply because after months of preparation I finally finished my first 10km running race!

It all started when my former team leader at work gave me a copy of Jogging International, a French-language magazine on running, early last year. It was a special edition on marathons, with various articles from training programs to diet and foot injuries. I don't know why exactly, but it spurred my interest in running. I actually had tried to run before that but holding that magazine in my hand made me more determined to really finish a marathon.

However, by summer (around June 2010) I realized that I was too heavy. A very slow run or even a brisk walk was enough to raise my heart rate to very high levels. So I started looking around for ways to lose weight.

An online friend introduced me to the P90X training program. This program was extremely difficult for me and it took me weeks to finally decide to commit to this program. I had to try some of the exercises, just to get a taste of it. After a session of the cardio routines (and watching a lot of testimonials on YouTube) I decided that I will do it.

I started doing classic P90X exercises in mid-September 2010, weighing in at 94kg. For the next two months, I religiously did the exercises, devoting at least an hour every night. I bought a pull-up bar, a heart rate monitor, a yoga mat, and a set of weights. The beauty of P90X is that you can easily do it at home.

The best part of P90X for me, however, was the diet. I followed the "portion approach" of the P90X diet. The fact that the first month of P90X required a protein-centric diet suits me just fine -- I love eating meat! Also, I like that I didn't have to go hungry just to lose weight. A grumbling stomach doesn't bode well for me in any case.

After 9 weeks of P90X (mid-November 2010), and losing 12kg of weight, I slowly shifted back to running. This was intentional because I was scheduled to go for a month-long vacation in the Philippines by December 2010. I didn't want to abruptly stop doing P90X, so I started skipping it on some nights and went running instead.

During my 5-week vacation in Manila, I wasn't able to do much sports. But surprisingly, I still managed to lose 2kg more. It must be due to the regular eating schedule that we had (my kids need to eat at regular intervals).

I resumed running upon my return from vacation. But then, I started having problems with my right foot. On January 24, 2011 I felt something ticked on my right foot, somewhere inside my heel, just as I was leaving my office. I suspected that it was due to the stress of running the day before that. But, I thought it was something that was gonna go away by itself.

Unfortunately, it didn't go away. I finally went to see my doctor on February 2, 2011. Ironically, it was an appointment that I set weeks earlier to get a medical certificate that will allow me to run in a race. You see I was already planning to run in the 10km race in Cannes (Le Semi de Cannes) on the 20th of February. So, obviously, I was disappointed that I couldn't go. The doctor gave me an anti-inflammatory drug and it gave me some relief. However, walking a few hundred meters was enough to trigger a bit of sharp pain just above the heel. For some twisted logic, I didn't go to a podiatrist or a sports doctor and simply limped along for the next few weeks. By early March 2011, however, my foot seems to have recovered.

If there was a good thing with my foot injury, it's that it forced me to change my style of running. I used to run with my heels hitting the ground first before my toes. In order to avoid feeling any pain with my right heel, I deliberately changed my step and forced my toe to hit the ground first. It's a bit difficult at first, but I already had previous experience with this thanks to the plyometric exercises in P90X where you have to jump and land on the floor with your only your toes hitting the ground. Also, my new pair of running shoes, Adidas Marathon 10, which I bought at half-price just before I got injured, easily allows me to run this way.

So, with my new style of running, I started monitoring my progress. I found RunKeeper which runs on my Android phone. At first, I ran a bit slower because I used to associate a toe-first step with slower jogging. But I kept at it, thinking that it's just like doing P90X Plyometrics. Soon enough, I was able to do sprints without hitting my heels on the ground.

And today, I was able to finally run 10km at a race: the 20th Semi-Marathon International de Nice! Official time: 01:03:00.69. This is also my best long-distance speed ever, faster than in any of my training runs. So I'm very, very pleased with myself today.

Next goal, a 21km race!

Finally, a new C++ standard!

2011-03-28T15:53:00.000+02:00

Earlier today, the ISO Working Group on the C++ programming language has approved the Final Draft International Standard (FDIS) for C++. The final ISO approval is expected to be in August 2011. So we can definitely call it C++2011.

As a C++ application developer, this is good news for me. There'll be lots of new things to learn about the language and better ways to write C++ code.

Thanks to the C++ Standards Committee!

Juan Luis Guerra: Mi Bendición (Guitar Chords and Lyrics)

2011-01-25T10:32:00.003+01:00

I discovered the Latin singer Juan Luis Guerra yesterday on Spotify and I fell in love with one of his songs "Mi Bendición". I couldn't find the guitar chords online so I decided to pick up my old guitar and write them down myself. Here goes...

Living in Manila

2010-12-29T09:41:00.000+01:00

It's great to be home with family and friends. More so when you're doing it during the Christmas holidays in the Philippines -- officially the world's longest.

I left Nice earlier this month to spend a bit more than a month in the Philippines. Since my wife now works in the country's financial capital city of Makati, we've decided to stay put in the Metro Manila area. It would've been more fun back in my hometown in Iligan, but the thought of having my first Christmas in the Philippine capital is actually a bit exciting.

For all the heavy traffic, the sea of people (at least 12 million people live in the National Capital Region), the pollution (noise, smoke, dust, you name it), you can't help but love Manila (unless all you want to do is jog or do a marathon -- because, really, you'd have to be a bit suicidal to run right next to Manila's roads). Manila is a city that NEVER sleeps. It's got almost everything an average guy like me could want -- provided you have money, of course. The ubiquitous shopping malls -- THE MALLS!!! I know, I know, it's unbridled capitalism but I sometimes wish they have a lot of those in France. They just make shopping so convenient.

I've never really liked the thought of living in Manila (or any capital city for that matter) but now that I've tried it, I am actually surprised to realize that it's not so bad after all!

Oh! Kinabuhi (Oh, Life!)

2010-09-17T11:43:00.001+02:00

I've just seen that video of famous boxer Manny Pacquiao singing a sort of medley of Visayan songs so I thought I'd post the lyrics and translation of one of them here. This song is called "Oh! Kinabuhi" by Filipino singer Victor Wood.

Oh! Kinabuhi
Victor Wood

Inig sidlak sa adlaw sa sayo sa kabuntagon
Masud-ong ta ang katahoman ning kalibutan
Gidayandayan sa nahigmata nga kalanggaman
Nga nanag-awit ning kabukiran

Ug mopadulong sa pagsalop sa kahapunon
Ug sa dughan nga walay naglaylay
Sa kasing-kasing nga way nagsapnay
Sama kanako nga sinalikway ay magamahay

Chorus:

Oh kinabuhi sama ka sa usa ka gapnod
Nga gianod-anod sa bul-og ning mga luha
Way kinutoban way hunong ang iyang guidulngan
Ayayay-ayayay nganong sakiton man.

Here's the English translation:

Oh Life!
by Victor Wood
(translated by Allister Sanchez)

When the sun shines early in the morning
We'll see the beauty of this world
Adorned by the awoken birds
That sing in these mountains

And it heads to set in the afternoon
And to the bossom where no one lulls
To the heart that no one cradles
Like me who's rejected, will be hurt

Chorus:

Oh life, like flotsam
Washed away in the rush of these tears
Unending, ceaseless in its destination
Ayayay-ayayay why ache over it?

Revisiting basic statistics

2010-07-08T17:21:00.005+02:00

A friend of mine works for a physical therapy clinic and she needed to decide if a certain patient's physical ability -- in this case, his hand grip strength -- is good enough. She let the patient use a strength measuring device and did 3 trial measurements. The device comes with a table of typical strengths (giving the average strength, μ, and the standard deviation, σ) for different age groups and gender.

From the 3 measurements, she calculated the average measured strength of the patient's hand grip. My friend's problem starts because the average measured strength is lower than the patient's age group's lower limit, μ-σ. Her question is: how can she trust the average of her 3 measurements, and thus conclude safely that the patient really has a weak hand grip?

To answer this question, we have to make an assumption that if the patient would have to make a large number (n) of trials, the measured grip strengths would vary or fluctuate around the average measurement and that if we draw a graph of the distribution of measurements, we would see a "bell curve", as shown below.

This curve is also known as the normal distribution, and is often the behavior of the result of measurement of many natural quantities.

But in most practical uses, we won't have data that will look like this smooth bell curve. Instead, what we have is a discrete graph of measured data that can only approach the bell curve when the number (n) of sample measurements becomes large enough, similar to this graph below:

As a consequence, we can see that the calculation of the average measurement can only be very reliable when the number (n) of sample measurements is large enough. But my friend will have to live with just 3 trial measurements (and the poor patient probably can't do a lot of tests). So is there a way she can test the usability of her results? Luckily, there is.

The average measured grip strength has a precision, ε, that can be calculated based on the standard deviation σ of the data and of number (n) of trials: ε = σ / sqrt( n ). Then we relate the value of ε to the coefficient of variation, σ/μ, of her measured data, which she calculated to be 0.15: ε/μ = (σ/μ)(1/sqrt( n)).

So, for just 3 trials, ε/μ = 0.15 / sqrt( 3 ) = 0.087. That is, the precision of the average measured grip strength is about 8.7% of its value. Hence, we can say that her measurements were precise enough and that the poor patient's grip strength is really lower than μ-σ. Simply said, the poor guy's hand grip is really weaker than more than 84% of his age group.

Disclaimer: Of course, my friend will have to decide for herself the proper course of treatment for her patient and this discussion should be taken with a grain of salt. For one, I have a feeling that the actual distribution for the higher-age groups don't really follow the normal distribution.

My first Adobe Flex application

2010-06-25T21:13:00.001+02:00

I have always liked learning about new programming tools and am always on the lookout for which tools would do best which job. From time to time, I check on the status of rich internet applications, and in particular Adobe Flex (or Adobe AIR), which is a great framework in case you want nice user interfaces.

Finally, my chance came. My wife needed a software to record and analyze the trend of prices of various products on the market. So, basically, she needed a convenient way to store information into a database and display it on a chart, a use some statistical tools to come up with business decisions. And most importantly, she needed soon -- in about a week's time.

Adobe Flex first came to my mind and after a quick research, I determined that it's the right tool for the job. It's very convenient for making graphical controls (text input, buttons, tables), data visualization (charts), and -- after a bit of clarification -- it handles local file databases (sqlite). These can all be done with just a single XML file with a sprinkling of ActionScript in places.

For my first attempt, I spent a whole weekend (2 days) to come up with something almost complete. However, I was not satisfied with how my code looked. So I rewrote the whole code, specially user interface, for another day. Not bad for someone who's never programmed in Flex before. And my wife was happy as a clam -- she even showed it to her boss :-)

I called TrendViewer and here are some snapshots.

Of course, there are still some tiny bugs to be fixed, and there might be some performance issues with bigger data sets in the future, but this weekend I'll take a well-deserved rest.

Looking for a Chinese name

2010-06-18T10:37:00.004+02:00

My second son, Andrew Meson, is now going to a new school since we moved late last month to the capital of the Philippines. It turns out that this school is catering to the East Asian community in the capital (mostly Chinese-, Korean-, and Japanese-Filipino students). And to add to our surprise, we were asked to give our son a Chinese name!

So, I spent the whole day yesterday trying to come up with a good name for my son. I already know some Chinese characters because I have learned Japanese during my stay as a student in Japan. Still, I found it a rather challenging task. So I can only wonder what it would be like for a parent who has no knowledge whatsoever of the Chinese language.

I found that many "baby names" websites actually have a list of popular Chinese names. So, if you don't want to complicate things, you just pick one from there. The downside is that it's not exactly tailored to what you might want for your child's name. For that I found the Mandarin Tools website really useful, in particular their Chinese character dictionary. Google's translation tool also helps, especially if you want to know the Chinese equivalent of common English names. Using it, I found that the Mandarin for Sanchez is 桑切斯 (Sāngqièsī). I've decided to use the first character (桑 Sāng, which literally means "mulberry tree") as the short version of our family name. And after several discussions with my wife, we've decided on our son's name: 桑梅森 (Sāng Méisēn).

So, did I pick a good name?

Football Frenzy!

2010-06-15T23:48:00.000+02:00

The biggest sports event of the planet, the FIFA World Cup 2010, has started last Friday, the 11th of June 2010. Finally, I am in a country where football reigns supreme -- unlike my native Philippines that's living inside it's own NBA basketball bubble -- so I get to watch ALL the games!

By tomorrow, all the teams will have played their first matches. Germany leads the pack with a staggering 4-0 slaughter of the Australians. Let's see if they can keep it up. South Korea also did a splendid 2-0 win over the sluggish Greeks, and so did the Dutch against the Danes (although in a less spectacular manner). The Brazilians, though not quite showing good teamwork, have managed to win 2-1 over the North Koreans.

The most memorable gaffe so far is that of England's goalkeeper Robert Green, and for his sake I hope someone else (perhaps the Spanish keeper? hehehehe) will commit a graver error. So I'm keeping my fingers crossed for tomorrow's match between Spain and Switzerland.

Till then, allez, allez, olé!

By the way, what do you think of those noisy vuvuzelas?

Converting 3gp video into avi format

2010-03-16T22:30:00.000+01:00

I had some video of my kids taken with my phone and are therefore in the 3GP format. The problem is that when tried to play them on my PC (running Ubuntu Linux), there's no sound. So I looked around and found the perfect solution: the Mobile Media Converter. It's a free, cross-platform (that is, it runs on Windows, Linux and Mac) converter of various mobile media formats to and from desktop PC media formats, namely:

Desktop audio: mp3, wma, ogg, ra (as input only)
Mobile audio: amr, mp4
Desktop video: mpeg, wmv, avi, flv, mov, rv (as input only)
Mobile video: 3gp, mp4

An installer for Ubuntu Linux is available and I quickly installed it with a few clicks. To the guys making this very useful -- and free -- tool, thanks a lot! I think I'll make a donation later.

Switch: Don't Solve Problems -- Copy Success Instead!

2010-02-02T23:35:00.001+01:00

I have read an excerpt of Chip Heath and Dan Heath's book "Switch". The idea of this book is this: to effect great change, instead of trying to analyse a problem, look at "bright spots" (areas with the least problems) and figure out why they are less problematic. This is a sort of roundabout way of how people usually address problems.

When we analyze a big, complicated problem -- like malnutrition in Vietnam, or a married couple nearing divorce, or a business on the verge of bankruptcy -- we seek a solution that befits the scale of the problem. If the problem is a round hole with a 24-inch diameter, our brains will go looking for a 24-inch peg to fill it. So, naturally, the experts on malnutrition in Vietnam wanted to talk about poverty and education and sanitation systems.

Our focus, in times of change, goes instinctively to the problems at hand. What's broken and how do we fix it? This troubleshooting mind-set serves us well -- most of the time. If you run a nuclear power plant and your diagnostics turn up a disturbing signal once per month, you should most certainly obsess about it and fix the problem. And if your child brings home a report card with five As and one F, it makes sense to freak out about the F.

But in times of change, this mind-set will backfire. If we need to make major changes, then (by definition) we don't have a near-spotless report card. A lot of things are probably wrong. The "report card" for our diet, or our marriage, or our business, is full of Cs and Ds and Fs. So if you ask yourself, What's broken and how do I fix it?, you'll simply spin your wheels. You'll spend a lot of time agonizing over issues that are TBU.

When it's time to change, we must look for bright spots -- the first signs that things are working, the first precious As and Bs on our report card. We need to ask ourselves a question that sounds simple but is, in fact, deeply unnatural: What's working and how can we do more of it?

The excerpt goes on to illustrate the various situations where this approach works well, and some cases where it might not. After reading the excerpt, I am so looking forward to getting my hands on a copy of this book.

Have you read the book already? Please share your thoughts about it!

Getting Started on Running

2010-01-16T17:30:00.001+01:00

I've been running on and off since last Summer (around June 2009), largely because I was alarmed that I was gaining too much weight and I felt rather heavy. After a few months of walks and occasionally intense runs, I've managed to regain my body's flexibility and agility, and I was able to develop a bit of endurance. The gains were actually very modest but I was very happy with the realization that I can actually do something about improving my well-being.

Then the holidays came and I took a 5-week vacation in the Philippines. While I was there, I tried to avoid the overly-convenient public transportation, opting instead to walk/run several blocks in the city. The hot weather took a bit of adjustment but it's the pollution and lack of safe running areas that made me realize how difficult it is to enjoy running in the country. So, I realized that while I'm still living in Nice I should take advantage of the relatively low levels of air pollution and the length of the Promenade des Anglais.

To add weight to my resolve, I now challenge myself to be able to finish in a marathon (yes, running a 42.195 km race) within a year!

I started to read about marathon training and, boy, was I surprised! This sport is no walk in the park! There's so much preparation and training needed. My boss at work is very supportive of my desire to run and was kind enough to lend me a copy of the French-language Jogging magazine's special issue on marathons, which contains various training programs for people who want to run in a marathon. I've also read various websites concerning the appropriate shoes, clothes, and other accessories like heart rate monitors. Proper exercises, hydration, and diet are also important to learn and understand. It's all fascinatingly simple and complicated at the same time!

Anyway, one has to get started somewhere. So yesterday, I bought new shirts, socks, a new pair of shoes, and a heart rate monitor. I made a mistake buying the shoes (it was for highly-arched feet, while I have flat feet) but I had them exchanged at the same store this morning.

Finally, earlier this afternoon I decided it was time for the rubber to hit the road. I haven't run for more than a month so it was a combination of brisk walking and slow running for about 30 mins, the main purpose being to monitor my heart rate.

The simple formula for the maximum heart rate (MHR) is 220 minus the age. That's MHR = 188 for me. I've read that in order to increase one's capacity for intense physical activity, one has to exercise at an intensity that increases the heart rate to 65-85% of the MHR for at least 20 mins, 3 to 5 times a week.

So today, I ran/walk averaging a heart rate of 144 bpm over 30 mins, covering a few kilometers toward the center of Nice. After that, I stopped monitoring and walked all the way back. I felt very comfortable at this level of intensity. The challenge will now be how to run faster and longer at about 70-80% MHR.

How about you? Would you like to run too? If you're already running, please share with me your experiences.

Welcoming the New Year 2010

I'm savoring the last few days of my month-long vacation. I'll be back in France next week and I'm spending the few remaining days with my family in the best way I can.

Overall, it's been a good vacation. It's not easy reinserting yourself into the daily lives of your wife and kids with whom you only interact over the internet for most of the year. But (thanks also to our frequent interactions online) we seem to have meshed well and rather quickly, as if we live in the same house together all year round. I really hope we'll still stay as close to each other in the coming months, when we're half a world apart.

Last year, 2009, for my family was, in a way, a year of settling down. This year, 2010, will be another year of change. After all, this is the year of the metallic tiger, and the beast is on the prowl. Time to shake things up.

So, my goals for this year? Personally, I'd like to lose a lot of weight. Professionally, I'd like to see large gains and strategic changes for the future. For my family, I'd like us to live together soon, or at least be in a better living arrangement. I know some of these are not very specific, but I'd rather keep some very important decisions private ;-)

I therefore look forward to the rest of 2010! We'll make this a better year than the previous one!

Joie dans le monde

2009-10-20T14:00:00.000+02:00

NOTE: This is the French version of the famous Christmas carol "Joy To The World". You have more than a month to practice it before Christmas

Joie dans le monde, c’est Noël;
Voici Emmanuel!
Que chaque cœur,
Lui fasse une demeure.
Que ciel et nature chantent
Que ciel et nature chantent:
Que ciel et ciel et nature chantent.

Joie sur la terre vive le Messie!
La loi est accomplie.
Ô humblement Jésus,
Vers nous Il est venu.
Rendez gloire au Seigneur,
Rendez gloire au Seigneur,
Rendez, rendez gloire au Seigneur.

Détournez vous de vos péchés,
Les âmes sont libérées.
Par Sa grâce et naissance,
Il nous donne espérance.
Venez comme des enfants,
Venez comme des enfants,
Venez, venez comme des enfants.

Il régnera en vérité,
Et justice à jamais!
Sa victoire est totale,
Jésus vaincu le mal,
Avec Son grand amour,
Avec Son grand amour,
Avec, avec Son grand amour.

Gotcha 8x8!

2009-04-04T11:03:00.007+02:00

I finally solved a 8x8 puzzle!!! Woohooo!!!

I opened it at the NY Times Kenken page last night before I went to sleep and decided to really have a crack at it this morning. About an hour's hard work finally paid off and, boy, ain't it sweet!

Here are some snapshots I took -- precautionary measures, in case I accidentally close the browser, hahaha...

One Year of Chocolate!

2009-04-02T20:27:00.004+02:00

I have just received this email ad from the French supermarket chain Casino. For some reason yet unknown to me, the French seem to promote chocolates for Easter (Pâques) -- perhaps to help them get through the Lenten season.

The other thing that got my attention is the promo game that says "1 an de chocolat à gagner!" One year's worth of cholocate to win! Hmm... I wonder what kind of game it is.

How to play Kenken

2009-03-22T07:14:00.000+01:00

Kenken is a numbers puzzle game like sudoku, and both are meant to be good for sharpening your arithmetic skills and your logic. You have a square grid (typically 4x4, 6x6 or 8x8) to be filled with numbers such that each number is unique in its own row and colum. The boxes in the grid are also partitioned into "cages"; often defined by a common thick border line. The numbers in a cage must produce the total number specified in the cage when the specified operation is applied to all the numbers in the cage. Here's an empty kenken board:

In the bottom row, for instance, we have 2 cages: one composed of 3 numbers (one for each box) whose sum (because the given operation is addition) is 6, the other cage has only one box containing number 4. No operation needs to be specified for a cage with only one box. So filling first the single-box cages, we have:

Now looking at the rightmost column, there's a 2-box cage with total 2 and operation division. Since we have a 4x4 grid (meaning, the only possible numbers are 1, 2, 3, 4), only 2 and 1 can be used to fill this 2-box cage. That leaves 3 as the only number for the remaining box at the top of the rightmost column.

Now that we've filled that upper-right-most box with 3, it's cage therefore has 3x1x3 = 9 (which we could actually deduce even without knowledge about the other boxes).

The topmost row has only one box left and it can only be 4. So the cage for that box (2 by division) contains 4 and 2 because 4/2=2.

Now we can go more quickly. The cage on the right (2 by division, 2/1=2) will have 1 in the upper box and 2 in the lower. The cage in the third row (7 by addition, 4+3=7) will have 3 in the left box and 4 on the right box.

Thus we can now easily deduce the complete solution. The cage in the first column (3 by subtraction, 4-1=3) will have 4 on the upper box and 1 on the lower box. The last cage at the bottom will have 3+1+2=6.

Yoohoo! We have just solved our first Kenken puzzle!
