Well, it might not be the fanciest thing in the world but it surely looks good when you try to visualize your data. You know me, I always graph whatever I do, otherwise I don’t get many ideas. I have to see what is going on, and perhaps are many people like me.
This time I’m gonna share a very simple and nice way to visualize the solution of a linear equation system with 3 unknowns and 3 equations. Continue reading
It’s no secret that the Chicano community is quite huge and one of the most complicated societies in the world, not only by their heritage, but because they always try to fit in the United States, while preserving their Mexican roots.
There is no easy analysis from this, but there is always something distinguishable from the Chicanos: comedy. Mexicans are brought up surrounded by laughter and celebration at any time (including Death), and that is one of the biggest legacies to the Chicanos.
My barrio, my beautiful barrio. This song makes me think of the old 50’s – 60’s Pachuco style with TinTán. The overstyled Zoot suits, the puns, the nostalgic voices singing in a dark bar, while the sadness is drunk away with a nice cold strong whisky, or maybe a cigar puts the mood, I don’t know, I can’t explain, just feel it… do you feel it?
One of the easiest and most useful tools in Matlab is polyval, a very nice function that evaluates a polynomial function given its parameters and the range to evaluate… huh? All right, all right, we wanna be clear here, right?
Suppose we are given a polynomial function, let’s say:
and we would like to represent it in Matlab like that. Well, we cannot just write it like that. Remember Matlab is a numerical computation programm, which means, that it won’t compute any symbol. So forget it if you wanna computate something writting letters. Matlabs wants only numbers. You might put names to the variables, but still, Matlab computes only with numbers.
Now, what to do? There’s where our great friend polyval comes to the rescue! Continue reading
Her artistic name is actually Aṣa but is pronounced “Asha”. Thanks to some strange paths that I follow listening my music (in other words: Spotify), I discovered this nigerian singer and Oh boy! I love her voice. I invite you to check more material from her, she has some pretty nice songs, the musical production and her voice make a perfect match in her style. Very joyful songs indeed.
This time I would like to share the song “Be my man”. Well, I won’t dedicate it to any person, but would be nice if some girl sings it to me the way Asha does. Huuuuh! The music is simply great and the rythm is highly contagious. It makes me wanna dance and sing it again and again.
Say youhuhuhuhuuuu!!
Without being a stereotype per se, the famous “May 5th” is loud and internationally linked to a Mexican celebration, but… what is supposed to be celebrated?
I’ll be short: the battle where Mexico defeated France. That’s all. In the second french intervention in Mexico (yes, they were two major french interventions in Mexico) in the middle of the XIX century, France invaded Mexico to annex it as a satellite state of France. The invasion started in Veracruz and headed to Mexico City, but in the middle of the way (in Puebla) the french army was slammed on the brakes and defeated by a totally underrated Mexican army.
Yes, as the title says, the best Octave tutorial out there is the one made by Professor Andrew Ng from Stanford. He started his world-famous Coursera almost two years ago. Now is one of the most successful companies in the world, why? Because it really gives what it promises and more: makes you understand Science.
Well, well go deep on it by yourself. These videos down are one of the first videos that Profr. Ng made for the course “Machine Learning”. I took it a year ago in its original website ml-class.org and it amazed me. I understood everything and didn’t have to smash my head to do so.
One of the chapters of his class was about handling Octave, the best free substitute for Matlab. Are you eager to master these computing tools? Dive into Octave next to Professor Ng. I promise you will be also amazed by the clear and concise way he teaches. This, my dear people, is the best Octave tutorial ever:

The vintage era sounds nowadays in my head. It all started with “Time of the Season” from The Zombies, and from there I started to make a big circle around that nice 50’s – 60’s rock era.
Oh my! Getting excited I increased the list with The Monkees, Tommy James & the Shondells, The Yardbirds, Janis Joplin, The Animals, Fats Domino… huh and the list goes on and on.
After listening along my memories, I ended up with the Zombies again. This song is punching in my head and makes me wanna jump and shout. Well, just gonna let you listen to this classic: “She’s not there” from the Zombies:
Free lectures! Free courses on-line! Free! Free!
Got your attention? I’m like spam.
So far, so good. It has been a year since I decided to get fully involved in this field of Computer Vision, and hasn’t been easy, but I gotta say it is full of surprises. My University has been strongly doing some research about it, and a proof of that is that the 3D Computer Vision course given in Coursera is actually done by a Professor in my university (tho in German). So, I think we’re moving quite strong.
My curiosity took me to the Computer Vision chair of the Informatics Department at the TUM and I think this semester they completely got me, as I’m planning to get the 3 lectures given there: Visual Navigation for Flying Robots, Multiple View Geometry and Machine Learning for Robotics and Computer Vision. Robotics, Machine Learning and Computer Vision! Makes my mouth water. Huh! Beautiful. Continue reading
Not sure if a late Easter egg, a passing joke or a permanent feature (would be fun), but Google gives us again the opportunity to play around with the common things on the internet.
This time comes all through Youtube. A new feature was added to the player of Youtube: the “Tape Mode”. You click it and your image will seem like an old VHS-cassette-like video. Quite nostalgic, I would say. I just discovered it watching some Ellen videos (I admit it, goddamit, that woman’s jokes are funny for me), and discovered this one with Steve Carell (better if you watch it in Youtube‘s website):
The legend says that they do it because of the 57th Anniversary of the commercial realease of the first VHS cassette. Well, quite a random number for me, but anyways. Not all videos have this feature. Apparently you just have to randomly find them too. Buuuu!!
Oh yeah, click “Pause” and it will keep the old effect of the cassette. These hipsters are everywhere with the electronic vintage effects. First their instagram, now this. I don’t think is gonna last, but I’d activate it for fun only.
Find a nice video and give it a try!
