More Than a Little Help

1 Share

Hace meses que no escribo. Voy a romper el silencio de blog para contar algo bastante shockeante que me sucedió hace unas semanas.

Estaba entrando a mi casa, cuando escuché una frenada fuerte. Llegué a darme vuelta para ver cómo un ómnibus impactaba fuertemente con un auto y lo tiraba 40 metros para atrás. En apenas segundos se llenó de vecinos que rodeaban al auto abollado, yo entre ellos. Al menos diez personas llamaban a ambulancias, 911, etc.

— Qué animal el de ómnibus – comentaba uno
— La culpa es del conductor que no respetó el Pare – decía otro
— Quién está en el auto? – Preguntó alguien más práctico
— Una mujer. Está muerta – Respondieron

Se me heló la sangre. Por la ventana del auto se veía a una mujer, de unos 35 años, con el cinturón puesto, la cabeza caída hacia el costado, casi tocando el asiento del acompañante. Un delgado hilo de sangre salía de su oreja.

Aún tengo fresco el curso de primeros auxilios que hice como parte de Helper (ver más abajo), pero mi susto pudo más. Hay 30 personas alrededor, me dije, qué puedo hacer? Además, está muerta, no puedo hacer nada. Me voy para casa. Chau. Vencido por la cobardía empecé a caminar para casa, mis piernas temblando. Una madre tapaba los ojos de sus hijos curiosos. Di unos pasos más, y me dije que no me puedo ir. Soy miembro de la directiva de Helper, lo mínimo que puedo hacer es alertar por la aplicación.

Abrí la aplicación de Helper. Grabé mi alerta: “Hubo un accidente en la esquina de casa, hay una mujer muerta adentro del auto”. En segundos empezó un chat vía la aplicación. “Sergio, fijate si respira”.

Me cayó una ficha. Quién dijo que está muerta? No hay nadie realmente cerca del auto. Nadie hace nada. Al menos voy a acercarme. Al acercarme escuché a alguien diciendo: La señora se mueve. Algo tengo que hacer, me dije. Le di el bolso de la computadora a alguien, ni se a quien. A todo esto, Michael, el fundador de Helper, me estaba llamando. “Sergio, escribí en la App la dirección exacta donde estas así alertamos una ambulancia, tu GPS marca mal”. Ingresé la dirección. Me ingresó otro llamado, no recuerdo quien era. Ni siquiera recuerdo si era hombre o mujer. Su voz transmitía calma y seguridad.

— Sergio, hay más gente en el auto?
— No, solo la mujer
— Está sangrando?
— No, solo tiene una herida menor, tiene la cabeza hacia un lado
— Bajala del auto y ponela en posición lateral de seguridad (es la posición que nos enseñaron para dejar a un herido mientras llega la ambulancia)
— No puedo, el auto está abollado
— OK, tenemos que alertar a bomberos, ya los estamos llamando. Vos asegurate de que tenga la cabeza derecha para que no se asfixie – Las cosas que aprendí en el curso iban volviendo, gracias a la voz del otro lado del teléfono que transmitía la calma que yo no tenía.

A todo esto, una mujer ya le estaba sujetando la cabeza a la señora. La gente de alrededor intentaba ayudar:

— Señora, manténgase despierta y no deje de respirar – Decía uno, sin darse cuenta de lo disparatado de sus instrucciones
— No la toquen, es peor – Trataba de ayudar otro. Las instrucciones del curso eran lo contrario: el riesgo de dañar a alguien es mucho menor que el riesgo de asfixia
— Soy médico – Dijo la señora que sujetaba la cabeza de la mujer derecha. Mi nivel de nervios bajó al oir eso, pero la voz disimulaba mal los nervios de la doctora, quien seguramente no estaba acostumbrada a situaciones de este tipo

La mujer del auto estaba consciente, pero en shock total. No gritaba, respondía alguna pregunta. Desde el teléfono me siguieron guiando. Yo lo único que hacía era transmitir las preguntas y las instrucciones a la doctora, que parecía estar como yo, agradecida de que alguien le diga (o le recuerde) lo que debe hacer.

Finalmente llegó la ambulancia. Me pareció que tardaron horas. Luego miré los registros, fueron 15 minutos, el promedio de lo que demora una ambulancia privada en Montevideo, y buen tiempo tomando en cuenta el tráfico del día. Los bomberos llegaron dos minutos después, y la policía un poco más tarde.

No sé que hubiera hecho yo si la doctora no estaba allí. Supongo que la presencia de gente del otro lado me hubiera ayudado a sobreponerme al susto y hacer lo que había que hacer. Sin la ayuda de la doctora y de Helper, la señora hubiera seguramente quedado dentro del auto durante 15 minutos, con riesgo de asfixia, mientras 30 personas a su alrededor le decían que siga respirando y discutían de quien es la culpa. Y los bomberos hubieran tardado 15 minutos más desde la llegada de la ambulancia.

Todo lo que conté es real. Como dije antes, soy parte del equipo fundador de la organización sin fines de lucro Helper. En Helper buscamos capacitar a 20.000 personas en primeros auxilios, y crear una red de primeros auxilios basada en una App. La App sirve para alertar Helpers capacitados que estén cerca, y cubrir los momentos críticos entre el evento y la llegada de la ambulancia.

Helper recién empieza, pero ya hay 1200 Helpers capacitados, y se atendieron cerca de 50 emergencias, varias de ellas críticas.

Siempre creí en el proyecto, llevado en gran parte por el entusiasmo de Michael. Ayer realmente entendí lo que implica el apoyo de la red. Podes hacer 10 cursos de primeros auxilios, pero tener un Helper al lado o del otro lado de la línea hace una enorme diferencia.

En los próximos meses seguramente escuchen mucho más de Helper. Todo apoyo es bienvenido, empezando por lo más básico, que es hacer el curso de Helper.

Binder: an awesome tool for hosting Jupyter notebooks

2 Shares

Thanks to a pull request today, I learned about a thing called Binder!! https://mybinder.org/.

Binder is a tool that lets other people easily launch an interactive copy of your Jupyter notebooks. I am SO STOKED that this exists, I have wanted it forever.

Here’s my pandas cookbook on Binder. You’ll need to wait for it to load and click ‘cookbook’ to try it out.

what’s a Jupyter notebook?

Jupyter notebooks (formerly called IPython notebooks) are an awesome way to combine code and text and images into an interactive document. I especially love them for doing data analysis – it’s basically life changing.

Here’s an example notebook analyzing some Montreal bike path data I made in 2013. You can see both the code, some explanations, and the output of the code all in one place!!

jupyter notebooks are easy to share online

If you want to share a Jupyter notebook on the internet, it’s super super easy (I just did it above!). There are at least 2 different services you can use (github and nbviewer)

nbviewer and github have both done this for a long time. This is great. But nbviewer isn’t interactive – it shows you a read-only version. So you can’t edit the code and experiment!

sharing interactive copies is important!

I used to occasionally run free Python intro data science workshops: we’d install pandas + the Jupyter notebook, do some fun data analysis, learn the basics. Here’s how it would go:

  1. write a bunch of materials before the workshop
  2. try to write really good installation instructions in advance
  3. go to the workshop. Someone is running Windows and I didn’t prepare for that
  4. struggle through installation with everyone and mostly survive

Having to install a bunch of software really sucks when you’re trying to get started with a new thing. And getting the scientific Python stack set up can be a pain (though tools like Anaconda definitely made it a lot easier)

Today there’s actually software designed for exactly this use case – you can set up JupyterHub on a server and have your workshop attendees sign into it. This didn’t exist when I was running workshops but it exists now and it looks awesome. You still need to set up the server which is nontrivial but that seems way better than supporting 30 people through installation issues.

binder = amazing

Binder lets you easily host interactive Jupyter notebooks and let anyone on the internet use them interactively immediately! It uses JupyterHub under the hood.

If you want to try it out, you can do that right now:

  1. Go to https://mybinder.org/v2/gh/jvns/pandas-cookbook/master (which will launch the github.com/jvns/pandas-cookbook repository)
  2. Wait for it to build and click ‘launch’
  3. click ‘cookbook’, click a notebook, and play around! There’s an “A quick tour of the IPython Notebook” notebook which shows off some of the basic features.

It apparently uses Kubernetes + Docker under the hood which is interesting! It must be much much more expensive to run than the read-only services, but it’s such a useful and cool thing! I hope it continues to exist.

There’s also the colaboratory by Google which is kinda the same thing, but it doesn’t work with github and only supports Chrome so it is less exciting to me. But still cool!

Effective Altruist Consumer Reports: Apple’s 27-inch iMac Pro vs. Ten Years of Education for Two Underprivileged Nepalese Girls

1 Comment and 4 Shares

Where price is concerned, the 27-inch iMac Pro and twenty collective years of education for the underprivileged Nepalese girls will cost you the same amount of money (about 2,000 USD). So to decide on the right option, we need to turn to features.

The new iMac boasts a stunning display with over a billion colors and a 1200:1 contrast ratio. This puts Apple on the cutting edge of lifelike graphic technology. At the same time, being placed in a school will keep these two Nepalese girls safe from sex trafficking, which affects over 20,000 Nepalese girls from poor communities every year. While the new iMac has four USB 3 ports and a powerful 4.2GHz quad-core Intel Core i7 processor, the Nepalese girls, given the opportunity of education with an only 3% dropout rate, can become safe, empowered, and valued in their communities after graduation.

The education for the girls seems to be winning except for the fact that it’s you yourself (or a close family member) who will enjoy the iMac. This has been boasted by Apple as a clear advantage to the iMac. After all, the education and safety for two underprivileged Nepalese girls will be enjoyed by the two Nepalese girls, not by yourself.

Upon closer examination, however, the fact that it is you yourself who will enjoy the iMac actually doesn’t provide a rational basis for buying it, unless your happiness at having the computer were more important than the vast and sustained improvement in the quality of life for these girls.

To objectively pick the best product, the educations or the iMac, one must ask oneself what one would prefer in this situation from the perspectives of all parties involved and also determine whose preference is stronger. You know that you want the iMac. And you know that if you were one of the girls, you would prefer that the money be spent on the education. This means, as the philosopher Richard Hare notes, that you yourself have a current preference that the education would be bought if you were one of the girls. Since this preference probably outweighs, in strength, your other current preference for the iMac, we can rationally conclude that this is where you should put your money.

(We might also add in the preferences of the exploited factory workers who have tried to kill themselves only to be thwarted by the anti-suicide nets set up in Apple’s Foxcon factory. We can presume that they have a strong preference that you boycott Apple until conditions for workers improve).

So while the iMac’s Bluetooth 4.2 wireless technology is exciting, the improvement in the quality of life for two Nepalese girls wins out in the long run. Plus, you can get a tax credit if you get the education for the girls and buy the iMac anyway, if you want to have and eat your cake. Alternatively, there’s always the $100 Lenovo Thinkpad, which only costs one year of education for a Nepalese girl.

The iMac is available here.

And the education for the girls is available here.

Oct 27th, 2017: SNEKs

2 Comments and 4 Shares
Mark Laita is a long time photographer fascinated by the shapes and colors of snakes, preferably just
after shedding when the colors are most vibrant.



Quote:

Handlers assisted him in laying each snake on a piece of black velvet, which slowed these fast movers enough to grab the photographs. The dark background also allowed the eye to focus on the form, texture, and color of the species. “By putting it on a black background, it removes all of the variables. It makes it just about the snake,” shared Laita. “If it is a red snake in the shape of a figure eight, all you have is this red swipe of color.”


Quote:

While photographing a black mamba at a facility in Central America, the deadly snake struck. “It was a very docile snake,” he recalls. “It just happened to move close to my feet at some point. The handler brought his hook in to move the snake, and he inadvertently snagged the cord from my camera. That scared the snake, and then it struck where it was warm. That happened to be the artery in my calf.” Miraculously, though the blood soaked through his socks and shoes, he survived the bite.


Quote:

Considering the black mamba's venom is deadly and can potentially make a person collapse within 45 minutes, Laita is extremely lucky. In fact, he was so preoccupied with the shoot, he didn't realize he'd been bitten until the handler told him. After 20 minutes of feeling ok, he decided not to seek medical attention—something herpetologists later told him was a big mistake because something could have happened even hours later. It was only the next day he realized he'd actually snapped a photograph of the bite as it occurred.
When will people realize sneks are sneaky, slimy, agents of Evil from Hell. :smack:
