being "agile" does not means being "scatterbrained"

I am not (and I do not attempt to be) a Scrum Master or any kind of agile guru, for that I have friends like Jesús Enrique Méndez (http://agileinpills.wordpress.com and his initiative http://www.agileopenspace.org), Gustavo Bonalde (http://gbonalde.blogspot.com/) or Carlos Gabriel (https://twitter.com/CarlosGabriel_). Anyway I am a guy that has spent a lot of time researching, studying, watching in silence how people do the stuff and secretly making some experiments; so I have developed my own opinions.

First, I believe that we need to be really agiles in our process, any kind of waste should be minimized, so why should we keep doing things in the most costly way (time related)?

Second, we need to be productive, that means that expending a year to develop a new functionality is unacceptable, even if you are developing an Operating System the process should not be that long.

Third, your business model or your economical maturity level could give you an advantage over other companies but that does not mean that you are allowed to make mistakes and if you are a small company or startup you will need to use properly any piece of resource that you can get.

Thinking in those three ideas, I usually see how people start being "agile" by ignoring any kind of design or worst, they start being "agile" and they stop thinking in the problem or the possible solutions and they start doing "anything" to solve the problem. I do not want to talk about efficiency or any related aspect to that, but let's take a time to understand the situation, let's draw something, let's get to the reasons of our problem and then we can solve it looking an good/optimal solution. If you want to be "agile" you can start by using the best simple solution instead of the most complicated solution. At this point my two advices are:

remember that thinking and designing are not sins.

keep it simple, do not oversize the problem.

I also see how people try to reduce the development cycle by doing something and sending it to the production environment as soon as they finish, then everybody gets crazy because something is falling; well, when I was a young developer, I learned about a technique (almost magical) to minimize troubles, it is called TESTING, we can not be in a rush and forget about tests, we HAVE to test our codes, obviously something can change and something could fail, but that HAS to be the exception and not the rule. I have saw people that is unable to send a functionality to production without having tons of errors and then breaking everything. Today, we have tools to automate our test, we can use jenkins or any other but we have to use it.

clumsy is not agile.

lazy is not agile.

testing is important for everybody, and we know that things can fail but it should be the exceptions.  

you can be agile testing, that does not mean NO TESTING.

Finally, I have saw people that as soon as they start getting error they start blaming any single API, third party tools or even the astrological configuration of mercury. People, let's face it, usually when something goes wrong we are the responsible, if we work in an orderly way, if we document our code, splitting the problems in smaller problems could make us agiles replacing broken pieces, fixing bugs or improving functionalities.

Well my friends, if you are trying to become an agile developer then you have my bless, just do it, but do it in the right way, do not become a "scatterbrained" trying to speed up developments.

chromecast is here!!

The last weekend i got my brand new Google Chromecast, First, it was a miracle because i got it just three days after the public release, THANKS AMAZON.COM!!! you are such a good friend!!

I will tell you my story with the device that made me feel so excited that I took pictures of the process.

The package as usual for google products was something clean, small and simple, basically nothing fancy (btw, i like that).

Then i got my first encounter with the device, i have to say that i bought it without watching or touching the device, so it was a mystery for me, but i was gratefully surprised. it is small enough to make it very portable, so you could take it with you anywhere you go.

Using it is really simple, plug it in any standard HDMI port, attention HDMI do not provide power to plugged devices, because of that you will need to power the Chromecast; do not worry about that because the devices comes with a USB cable + power adapter, so you could get the power from the USB port of the TV or any power outlet.








Now, you need to setup the device, it is extremely easy to do it, First go to https://cast.google.com/chromecast/setup and click in the download button, the magic will start there.

After installing the driver, the setup will detect your wireless connection and it will ask you for a name for the device.

And after doing that, you will be prompted to install the Google Chrome Extension (DO IT).

You know what, that was it!! Your Google Chromecast should be ready to use it!!! HOORRAH!!!

So, after playing a lot with the device. the good is:

1. Extremely portable device
2. Extremely easy to setup
3. It is multi platform, this really works with apple devices, android devices, laptops, tablets, etc. As a friendly reminder the Apple TV just works with Apple devices.
4. Native apps are the ones that get connected to the device, so you do not need to purchase something special to use a new phone or tablet, just get the youtube app, chrome app, etc. As a friendly, reminder roku could become messy and expensive in this point.
5. It is open, YES IT IS OPEN, so if you want to develop an app to stream from Frostwire to the TV, then you need to use the API, so any content provider or content aggregator could build their owns apps or any third party could do it. Do i have to said something about Apple TV?? well, i will... YOU CAN NOT DO IT, you have to wait for updates.. Even roku allows you to "create channels".
6. It is possible to broadcast in HD, with the Apple TV it was frustrating that Air Playing a CBS video stops every 5 seconds and every single document make reference to "network capabilities", COME ON!!! i have a linksys wireless router, i am not using any generic homemade solutions..
7. The device includes everything you need to use it, you do not need to purchase any extra stuff. For a limited time it was including a 3 months free Netflix subscription, that means to me that the device cost was USD 5 instead of USD 35 because i will save around USD 9 monthly.
8. Did i say that it is cheap and works??

Not everything is perfect, so i will tell you what i think that is bad:

1. the temperature is not exactly low, but well, it works with electricity and i am sure they know it is something to improve and it is not critical.
2. If you are using a really old device like a laptop with a 802.11 a/b card from 6 years ago, it could be slow and you will need to reduce the resolution.

In conclusion, we are talking about a killing device, its openness create a path for the creativity of any developer that could imagine even a Raspberry Pi running android and connected to this device, this is lovely.. Finally, i had to do to more things, 1.- Remove the Roku 3 from my "toys" wish-list in amazon.com and 2.- looking for someone that would like to buy my old Apple TV.

I really love my new toy!!
