The dark, hidden side of our technical communities

For a long time now, I’ve been wishing to write about the gender and diversity gap in the technical community. Today felt like that day, so here it is. It’s the longest post I have ever written, I think. Don’t worry, you don’t have to read it now. Save it for when you have some time to spare. No TL/DR here, I’m afraid.

As an active community member for some years now, I’ve been exposed to the rich ecosystem of user groups, formal and informal events, online collaboration, banter and gossip, articles, blog posts and other outlets of the technical community at large and SharePoint-specific community in particular. The personal rewards of interacting with other people in the community are enormous, and I feel grateful for the insights I got and for the opportunity to exchange points of view. Based on a voluntary participation, the community is one of the best examples of intrinsic motivation that I have ever seen.

However, the technical community isn’t the rose-painted picture nor it exists in the void. The real-world issues also seep into the technical community and not all what I have seen inside is something that I’d like to see again. I’ll try to explain it in the following lines.

The technical community is based mainly on the underlying politics of meritocracy. The more you work to benefit the community, the more benefit you get from doing it. We are used to think that our communities are as egalitarian and democratic as possible, but it’s a flawed illusion.

Who is the “community”?

Enter the blissful ignorance of conformity bias.

Let me check the circles of my personal interactions in the community. Mainly I’ve been involved in Spanish technical community around Microsoft technologies. I also have an active European participation, mainly in community-run events. In the end, I have participated in a couple of US and Canadian events, but my main field of action is Spain and Europe. I feel enriched by my community work, but let’s make a closer look.

Even in the Spanish community, I’ve been mostly involved with the people I know well, mainly the Spanish MVPs and user group leaders. We know each other as we always hang around the same events, and thus unintentionally we create a “inner circle” in the community that makes it difficult for new people to come inside. It’s not that there aren’t any new community members, but it’s more of a mental barrier of always having “the usual suspects”. I have heard several comments lately from bright technical people that don’t submit to events because “there are always the same guys” speaking there.

And there’s true to that. It’s true that in the Microsoft communities the preponderance of MVPs in the speaker rosters is something that makes it easier for the attendees to choose interesting events but it also shuts the door (or leaves it almost closed) for new people and new blood in the community. As MVPs we have to do community activities to keep our MVP status, and I think that it has this side-effect of erecting walls around the technical events for potential speakers that aren’t part of the “privileged” few.

Furthermore, my community interactions are mainly with the people similar to me: white males, with university studies, middle to upper-middle class. For years I’ve been blissfully ignorant of the biased world I was in, but for some time I’ve been growing a conscience that ultimately makes me write this post, due to several things in the last years. I’ll line them up for you, if you are still with me.

Women in Technology

Vanessa Estorach is one of the founders of “Women in Mobile”, an advocacy group that helps raise the profile of women in the male-dominant world of mobile technology and marketing. She also happens to be my wife. She explains to me that one of the problems women face in the tech sector is that they have no role models. I haven’t thought about that before, but it’s painstakingly clear: while the boys have Bill Gates, Linus Torvalds or Mark Zuckerberg (nerd, geek stereotype included), the girls have no modern Ada Lovelace to refer to. I can only see some timid examples such as Marissa Meyer in Yahoo!. In fact, the stereotyped image of a tech person as a young nerd with zero social skills is the main factor that drives the girls out of technical careers even before stepping in.

I also read the “Lean In” book by Sheryl Sandberg, where Sheryl, a Facebook COO, paints a feminine/feminist view of a more egalitarian tech world and how to “lean in” to make it possible. My main takeaway from the book was there is a lot of effort to be done if we really want to see some change.

And last, but not the least, I’ve been subscribed to a newsletter called “Technically Speaking” for some time. It’s run by Chiu-Ki Chan and Cate Huston who write about technical speaking, a subject dear to my heard, but from the point of view of a minority, with special focus on codes of conduct and inclusive events. They are a female voice in a male-dominated sector, and collect positive examples of more diverse events and community. Their newsletters struck a chord in me and made me conscious of the “granted by default” privileges that I have as a white male, first-world technical community member.

The more I read and discussed about the “gender gap”, the more I felt that I could do more. I started to raise the issue at my work, in discussions with HR and management. I made a conscious choice of positive discrimination, recommending women over men from the candidates pool for our new hires. While positive discrimination is a discrimination, I think that it’s necessary until the field is leveled and the things regulate themselves. We have to apply extra effort to change the inertia that by itself will only perpetuate the existing situation, that’s why we have to discriminate positively.

Woman with laptop

However, the one thing that I try to avoid is to foster a token female presence. To have a single women in the team is almost as bad as having none. There is some research that says that starting with 3 women in the team is when you begin to see the effects of more diversity of opinion.

My community “girls club”

While my community circles are still mainly “boy clubs”, I have to acknowledge remarkable women in the community that I have the privilege of knowing personally:

  • Cristina González, the MVP lead for Spain, Portugal, Italy (and some other countries). The envy of other MVPs who don’t have the privilege of having her as their lead, she has a soft and caring communication style and a brilliant mind that makes for very interesting conversations.
  • Martina Grom, Office 365 MVP from Austria. For me she’s the embodiment of what I’d like to see more in the world: a competent professional, engaged in the community and true to her values about the women in the IT.
  • Agnes Molnar, SharePoint MVP from Hungary. Agnes is a mother of three and a frequent community speaker and traveler. If that wasn’t enough, she even writes books and helps other women in the IT.
  • Isabel Cabezas, Microsoft Technical Evangelist from Spain. Isabel is a former student of mine, that became coworker and now she participates in Microsoft Developer Experience team in Spain to communicate her passion about technology. Isabel also works to fix the gender gap by organizing events such as Ada Code Group or AdaJS/JSLadies.
  • Iris Classon, Swedish MVP. Iris was a dietitian who discovered programming in 2011 and hasn’t been looking back since then. Her passion for technology is unbounded and she transmits it on her talks and her blog. While I still can’t make my mind about whether her previous look was a good or a bad role model for women in IT, she’s undeniably an example for other women in the programming community.

Beyond gender inequality

So, if we have more women in the technology, then the problem is solved, right? Well…there are still some issues beyond the mere presence of female talent in the community.

Do the women in the IT feel welcome in the community? The sexual harassment raises its ugly head even in our meritocratic communities. We won’t have more diverse communities without eradicating sexist jokes, patronizing talk and innuendo. There have been several high-profile incidents in the technical events lately, and we’re talking about supposedly more-than-average open and forward-looking communities.

What about the lactating mothers who want to come to an event? Will they feel welcome? And even for the parents regardless of the gender, what if they want to bring their children to the conference? How can we make it possible so that they won’t have to pay a babysitter?

And that’s only one of the diversity issues in our communities: the gender gap. But there are many more lurking around. How many times you had a speaker from emerging countries? By focusing ourselves on our cozy Western environment, we lose the valuable insights of the people whose experiences in the IT are radically different in scope and impact.

What about the economic inequality? As a members of the privileged middle-class, we tend to forget that not everyone can afford to travel to a conference to speak, even more so in the real community events where the budget is stretched. It’s a real barrier to more diverse events, and I can feel it even in Spain where outside Barcelona and Madrid, few speakers can show up because of the economic downturn that hit the areas outside the metropolis much harder. How many voices we lose due to the companies that can’t (or won’t) pay the travel costs for their people?

What about the people with disabilities? Can they participate in the technical community as it is now? Or do we need to change the community itself. Even such a small detail as the wheelchair ramp or the subtitles for people with hearing problems can mean that a person who wants to participate cannot do so.

What about the LGBT people in the technical world? Do they feel welcome when somebody cracks a joke or uses a derogatory term even without thinking about it. There is a sincere post on Medium by a black lesbian programmer and her experiences about the diversity in the tech industry.

I have just scratched the surface of the unconscious bias that we have in our technical communities. You can find a lot, lot more information just by searching on Internet. For example, the Python community has a set of guiding principles for a more inclusive community.

Diverse world

What can I do about it?

So, what can I personally do to foster the more diverse community? As a user group leader and a technical speaker I do have some freedom of action and I intend to do something to increase the diversity:

  • I will make our user group events (such as SharePoint Saturday Barcelona) more inclusive by inviting speakers outside our “white, privileged boys club” and by helping that everyone who wants to participate can do so, regardless of the gender, sex, sexual preferences, economic situation or physical condition
  • I will promote the awareness of the diversity gap in the technical community and be vocal about it
  • I will decline to participate in the events where there’s no effort to bring more diverse backgrounds or where there’s no clear code of conduct (such as this one for instance)

I know that I won’t change the world, as I realized many years ago I can’t change it by myself. What I can do, however, is change what I do. By “being the change you want to see in the world” I can stay coherent with my beliefs and help bring in a richer, more diverse world to the communities I’m involved with.


¿Cómo me mantengo al día de la información técnica?

Mucha gente me ha preguntado como consigo estar al día de las novedades tecnológicas del mundillo SharePoint/NET/Web/JS sin morir en el intento. En este post intentaré resumir lo que hago yo.


Ojo, no sugiero que lo que me funciona a mí te va a funcionar a ti también, pero por intentar que no quede, ¿verdad?

Fuente de información #1: Twitter

Uso Twitter para filtrar las noticias importantes. La lógica es la siguiente: si sigo a la gente que más o menos son de mi perfil tecnológico, es muy probable que twiteen o retwiteen noticias o contenido interesante para mí. En este sentido, mi red de contactos actúa como una caja de resonancia de lo verdaderamente importante.

Fuente de información #2: Newsletters

Para la información más detallada y “asíncrona”, estoy suscrito a varias newsletters que me envían periódicamente noticias de interés sin demasiada “paja” de relleno. Os pongo aquí las que me llegan:

  • InfoQ – Si tuviera que recalcar una publicación, sería esta. Son los organizadores de la QCon, la conferencia de desarrollo que se celebra en varias ciudades cada año. Principalmente me interesan las noticias de .NET, arquitectura y de prácticas de equipo.
  • Simple Talk – El newsletter de la gente de Red Gate. Un poco orientado a sus productos de profiling y de gestión de BBDD, pero con el contenido bastante útil al final.
  • DZone – Noticias de desarrollo, arquitectura y un poco de gestión de proyectos infomáticos. No tan útil para mí como InfoQ, pero de vez en cuando hay algo interesante como este artículo.
  • Methods & Tools – Es una publicación un poco “retro” orientada a desarrolladores y arquitectos. Publican una revista PDF cada 6 meses con artículos interesantes.
  • SharePoint Community – Noticias y novedades del mundillo SharePoint y Office 365.
  • Technically Speaking – Es el newsletter más personal que recibo. Lo edita Chiu-Ki Chan, una desarrolladora ex-Google que vive en EEUU. Los temas que cubre son básicamente “call for speakers”, organizar conferencias y charlas, hablar en público y la igualdad de género en la informática. Me va muy bien para mi “trabajo” en SUG.CAT.

Fuente de información #3: Revistas

Las revistas (en PDF y en papel) siguen siendo mi fuente de información “en profundidad”. Me inspiran para probar cosas nuevas y me dan ese conocimiento previo a meterse a trastear con algo nuevo.

Me suscribo para que me lleguen a mi buzón cuando haya un nuevo número.

  • MSDN Magazine – La revista “oficial” de .NET, con artículos de calidad (aunque a veces demasiado alejados del día a día) y temas en el “cutting edge” como dirían los anglosajones. Disponible en papel, en PDF y online.
  • DotNetCurry – La revista india de .NET. Artículos más asequibles, aunque la maquetación es a veces demasiado “Bollywood”. Hacen entrevistas a gente destacada del mundillo .NET.
  • Compartimoss – “LA” revista de SharePoint de habla hispana. Si eres SharePointero (o Office 365ero) la debes seguir. Punto.
  • DIWUG eMagazine – Revista en inglés de SharePoint, editada por el grupo de usuarios de SharePoint de Países Bajos. Artículos de mucha calidad. A veces está disponible en papel, en eventos europeos de SharePoint.

Fuente de información #4: Blogs

Siguiendo con la información en profundidad, sigo usando un agregador de blogs (ahora mismo Feedly). Allí tengo una colección de blogs de NET, de SharePoint, de otros hobbies y de compañeros como Robert Bermejo, que está que se sale con su blog de Azure.

Otro tipo de blogs que sigo son los de agregación de novedades, como Variable Not Found y This Week in .NET.

¿Cómo gestiono todo esto?

Aquí está la proverbial “madre del cordero”. Con el tiempo que tengo al día, ¿cómo gestiono todas estas fuentes de información?

Lo que hago es aprovechar el viaje en metro de cada día para ponerme echar un vistazo a Twitter y a Feedly. Si hay algo que merece una lectura más profunda, me lo apunto en OneNote.

Los newsletters y las revistas llegan cuando llegan. Lo que hago es programarme su lectura: un ratito el fin de semana, en el descanso, en un viaje… Lo mismo hago con las cosas apuntadas en OneNote: me programo su lectura.

Al mediodía, después de comer, echo otra batida por Twitter a ver si hay algo nuevo. Igual que por la mañana, apunto en OneNote cosas de interés para leérmelas con más detalle.

Supongo que mi flujo de información no es todo lo óptimo que podría ser, pero de momento me da buenos resultados. Al final, creo que es responsabilidad personal de cada profesional estar al día de su ámbito de acción.

Y vosotros, ¿qué pensáis?


UpdatePanel Troubles with SharePoint 2013

Few weeks ago I had a nasty bug on customer premises where a combination of SharePoint 2013 and ASP.NET UpdatePanel control resulted in some very weird behaviour.


Our project consisted of several full-trust code ASPX pages, dutifully placed in _layouts folder. Two of these pages had ASP.NET AJAX UpdatePanel controls to give “a kind of” smooth user interaction experience. The reason to use it was the simplicity of wrapping the existing SharePoint server controls such as grids and buttons in the update panel to prevent page reloads on postbacks. (Yes, I know it’s legacy technology but still, sometimes it’s the best and simplest solution for a given problem).

However, these pages gave random errors as if their event was somehow lost between the UpdatePanel client-side code and the server-side postback. Randomly, we had errors in our pages, with no discernible pattern. The only clue was in the ULS logs, where there were no user claims associated with the request, as if it were a non-authenticated call. What’s worse, as it had no clear cause, our reproduction procedure was to mindlessly click the buttons in the hope of a random error. Needless to say, it was way too inefficient.

Googling around, I found a way to reproduce the errors using Fiddler HTTP debugging tool. The sequence of steps is to make the first page load with Fiddler running in the background. Then, I deleted all the captured traces in Fiddler and clicked the button inside UpdatePanel. Immediately, the UpdatePanel threw the dreaded error.


According to the Microsoft KB3062825 article, the cause is the mismatch between the HTTP protocol implementation in UpdatePanel and SharePoint 2013, where instead of returning a 401 code in the handshake, SharePoint returns 200 with the login redirect and the UpdatePanel loses its changes. It only applied to a certain combination of SharePoint 2013 and .NET Framework, and even in these combination it wasn’t certain that the error would happen.

Unfortunately, we were in that situation, with the right combination of SharePoint and .NET versions.


The solution is simple: applying a specific .NET Framework hotfix (for Windows Server 2012 R2, for Windows Server 2012) that’s meant to patch the HTTP protocol handling causing the error. The patch is available via Microsoft support, but it’s not publicly available. I think that it’s because the error isn’t deterministic enough to be included in a regular cumulative update or service pack.

You also have to install SharePoint 2013 SP1, together with a Cumulative Update from December 2014 (or later).

“Jotasón” y la (mala) pronunciación de términos informáticos

Los que me conocen saben que soy un poco Grammar Nazi. Lo reconozco, me gusta corregir la ortografía o la pronunciación en inglés cuando se trata de gente a la que aprecio, como amigos o compañeros. No hace falta añadir que no lo hago por fastidiar sino siempre con el afán de que mejoren su expresión oral en inglés, lo que abre muchísimas puertas en el mundo profesional y sobre todo en el de la informática.

A lo largo de los años he ido guardando mentalmente las pronunciaciones de palabras técnicas más frecuentes. Aquí os presento la lista, con la pronunciación aproximada mala y la buena.

(Agradecimientos a Robert Bermejo por ser el artífice de alguna palabra de la lista. Os recomiendo su blog por si tenéis algún interés en Azure)

Término Pronunciación incorrecta aproximada

Speaking at SharePoint Konferenz Erding 2016

Last week I was in Germany, in the little village of Erding (near Munich), delivering two sessions at SharePoint Konferenz 2016. It was a very good event with fantastic speaker lineup and nice environment.

SPKonferenz banner

My two sessions were Extending Authentication and Authorization and High-Trust SharePoint Add-Ins for On-Premises Development.

SPKonferenz Keynote
SPKonferenz Keynote Speakers

Extending Authentication and Authorization

In this talk I focused on explaining the architecture of claims identity in SharePoint. From there I went to explain how to extend the claims with custom claim providers, together with the explanation on how to use other identity providers such as ADFS or Thinktecture Identity Server with SharePoint. I had a fairly good Q&A session after my talk.

You can find the sample claim provider code at

High-Trust SharePoint Add-Ins for On-Premises Development

My second session was focused on how to build on-premises apps/add-ins (high-trust or S2S) using certificate authentication instead of OAuth-brokered authentication. I highlighted some of the challenges and also some of the extensibility points that we don’t have in low-trust apps. Again, I had nice Q&A time after my talk.

Hablando de Reactive Extension en DotNetSpain 2016

La semana pasada estuve participando en la mayor conferencia de .NET que se hace en España: la DotNetSpain Conference 2016. Este año se celebró en las instalaciones de Kinépolis, en Ciudad de la Imagen (Pozuelo de Alarcón). La zona me la conozco muy bien porque estuve “viviendo” allí durante unos meses para un proyecto de Microsoft Consulting Services.


Más de 1700 personas asistieron al evento, entre los cuales unos cuantos compañeros de Sogeti España. Como muchos sabéis, soy un firme defensor de la comunidad técnica como una fuente de conocimiento, de inspiración y de contactos. Por ello animo siempre a mis compañeros a asistir y a ayudar en medida de lo posible.

Las charlas de la DotNetSpain 2016 fueron muy interesantes desde el punto de vista técnico. Además, pudimos disfrutar de la visita del mismísimo Satya Nadella, el CEO de Microsoft. Para mí, la conferencia fue un día para aprender, conocer gente nueva y reencontrarse con los conocidos.


En DotNetSpain 2016 hablé de Reactive Extensions (Rx), una librería de Microsoft poco conocida en el mundo “mainstream” de .NET pero que es muy potente para modelar aplicaciones que tienen que gestionar eventos o flujos asíncronos de datos. Afortunadamente, pude grabar la sesión usando un jueguete nuevo que tenemos en SUG.CAT y el video ya está colgado en Channel9.

La presentación está en SlideShare y el código fuente utilizado está disponible en GitHub.

Espero vuestros comentarios.

Creative Uses of IDisposable

We all know IDisposable interface in NET Framework. It is used to signal to any object with dependencies to other objects when should it dispose of them. IDisposable is a very handy feature together with the using statement, when IDisposable is called automatically when we exit a using code block.

I was reading the Introduction to Rx by Lee Campbell, in preparation of my session for DotNetSpain conference in February. There, I’ve found some creative uses of IDisposable.

Basically, it leverages the fact that Dispose method is called after “using” statement code block exits. So, we can use it to do some wrapping around that code block.

Before the code in the block is executed, the IDisposable constructor will be invoked. After the code is executed, the Dispose method will be invoked. In effect, our code will be surrounded by “Pre” and “Post” actions in an elegant way.

In Campbell’s exemple, a console app can leverage IDisposable to print text in different color inside a code block.

The “wrapper” is a short class named ConsoleColor that implements IDisposable. It remembers the previous console foreground color by saving it in the constructor and restoring it in the Dispose method.

The calling code just decorates Console.WriteLine code blocks with custom ConsoleColor instances, and voilà, we have a multi-color console application.


Book Review of “Debugging Teams” and “Exercises for Programmers”

In the last couple of weeks I’ve been reading two books that I hoped would help me with my role as a practice lead.

debugging teams cover page

One of them is “Debugging Teams” by Brian Fitzpatrick and Ben Collins-Sussman published by O’Reilly. It is a small book of around 150 pages, filled with practical advice on how to make successful teams that work and collaborate together. When I started reading it, it reminded me of a book I read a year back called “Team Geek”. Of course, I missed the clue that “Debugging Teams” is a rewrite of “Team Geek”, expanded to include feedback from the first book.

The main advice of Debugging Teams is a simple idea of practicing HRT (Humility, Respect and Trust). It permeates the whole book as a effective acronym to remember during your team leadership work. The rest of practical advices in the book include how to manage conflict, how to make a strong team ethos, how to navigate the organizational hierarchies and so on.

Debugging Teams, in essence, is a great update to an already great book. I’d rate it with 5 stars, wholeheartedly.

exercises for programmers cover pageexercises for programmers cover page

The second book is even smaller, but equally useful. It is called “Exercises for Programmers” by Brian P. Hogan, published under the umbrella of Pragmatic Programmers brand. With the subtitle of “57 challenges to develop your coding skills”, it is an exercise book that begins with “Hello, world” challenges and ends with complete small projects such as to-do lists or URL shorteners.

I use it now to send bi-weekly code challenges to my team. We then sit together to do a joint code review of each individual solution, in order to learn from it how to improve the code legibility and mantainability. It is equally suitable to use it as a source for code katas, test-driven development (TDD) assignments or self-study challenges when learning a new programming language.

My review of the “Exercises for Programmers” is 4 out of 5, just because many programs are very simplistic and also because several examples in it are maybe too US-centric (use of imperial units and USA-specific jargon) for a universally applicable book. Having said that, it is also a must-have if you want to challenge your (or your team’s) programming skills.


Talking about Claims and Claim Providers at ESPC15 in Stockholm

Last week I was in Stockholm for the annual European SharePoint Conference 2015. A little bit tired after being in USA for MVP Summit the previous week, but happy to meet my dear SharePointers and get to know some new ones.

Me at ESPC15
Me at ESPC15

My talk was about “Extending Authentication and Authorization”. I talked about claims, the underpinning of all thinks AuthN and AuthZ in SharePoint 2013. My demo was a custom claims provider that exposed dummy claims in People Picker that were used to protect confidential document from normal users.

I also demoed the federated authentication with SharePoint and ADFS.

My Session announced at ESPC15

You can find my slides on the ESPC15 website or on SlideShare. The demo claims provider code is also available on my OneDrive.

Special thanks to Spencer Harbar for coming with the claims as boarding pass analogy in the first place. It’s a great explanation tool.

Learn Building Highly Scalable Applications in Azure

In the first half of this year I’ve been busy producing a new course for Pluralsight, called “Building Highly Scalable Web Applications in Azure”. It is a course about making a normal web applications scalable to thousands and millions of users.

In my opinion, the majority of the development tutorials that show you how to make a web application do just that: they show you how to make a demo application. This demo application isn’t supposed to be production-ready nor should support high user loads. But, what happens when you need a scalable application? This is the missing piece I thought I could provide with my course.

Slide from my Pluralsight course

The course takes a simple web application named Ticketer, a simple-but-complete event and ticketing MVC 5 application, and refactors it into a scalable, redundant version of itself using a variety of techniques such as storage locking removal, caching, asynchronous calls or non-relational data storage.

In the following clip you can see the load test of the application before and after the scalability improvements.

Questions? Leave a comment and I’ll do my best to answer it.
