Future as a developer and the ever changing picture


A few weeks ago I came by a couple of articles my Marco Arment that share the theme of the current status of accelerated change within the development community as a way of stressing up, and being difficult to be up to date. After all, one gets tired of learning a new framework or language every size months. It gets to a point where is not funny or interesting anymore.

It seems like two different options are presented, that are available for developers after some time:

  • Keep up, meaning that you adopt rapidly each new technology
  • Move to other areas, typically management

Both are totally valid options, as I already said in this blog that I don’t like when good developers move to different areas (to me it’s sort of a surgeon deciding she had enough after a few years and move to manage the hospital). Though, obviously each person has absolutely every right to choose their career path.

But I think that it’s all mostly based in an biased and incorrect view of the field of technology and the real pace of changes.

In the last years, there has been an explosion of technologies, in particular for web. Ruby on Rails almost feels introduced at the same time as COBOL. NodeJS seemed to be in fashion for a while. The same with MongoDB or jQuery.

We all know that being stressed is not a great way of learn

We all know that being stressed is not a great way of learn

In the last 6 or 7 years there has been an incredible explosion in terms of open source fragmentation. Probably because GitHub (and other online repos) and the increase in communication through the Internet, the bar to create a web framework and offer it to the world has been lowered so much, that a lot of projects that would’ve been not exposed previously, has gotten more exposure. As a general effect, is positive, but it came with the negative effect that every year there is a revolution in terms of technologies, which forces everyone to catch up and learn the brand new tool that is the best for the current development, increasing the churning of buzz words.

But all this is nothing but an illusion. We developers tend to laugh at the common “minimum 3+ years of experience in Swift”, but we still get the notion that we should be experts in a particular language, DB or framework since day one. Of course, of the one on demand today, or we are just outdated, dinosaurs that should retire.

Software development is a young field, full of young people. That’s great in a lot of aspects, but we need to appreciate experience, even if it comes from using a different technology. It doesn’t look like it, but there’s still a lot of projects done in “not-so-fancy” technologies. That includes really old stuff like Fortran or COBOL, but also C++, Java, Perl, PHP or Ruby.

Technologies gets established by a combination of features, maturity, community and a little luck.  But once they are established, they’re quite resilient and don’t go away easily.  They are useful for quite a long time. Right now it’s not that difficult to pick a tool that is almost guaranteed to be around in the next 10-15 years. Also, most of the real important stuff is totally technology agnostic, things like write clean code, structure, debug ability, communication, team work, transform abstract ideas into concrete implementations, etc… That simply does not go away.

Think about this. iOS development started in 2008. Smartphones are radically different beasts than the ones available 6 years ago, probably the environment that has changed more. The basics are the same, though. And even if Swift has been introduced this year, it’s based in the same principles. Every year there has been tweaks, changing APIs, new functionalities. But the basic ideas are still the same. Today a new web development using LAMP is totally viable. Video games still relay on C++ and OpenGL. Java is still heavily used. I use all the time ideas mainly developed in the 70s like UNIX command line or Vim.

Just because every day we get tons of news about new startups setting up applications on new paradigms, that doesn’t mean that they don’t coexist with “older” technologies.

Of course, there are new tricks to learn, but it’s a day by day additive effort. Real revolution and change of paradigm is rare, and normally not a good sign. Changing from MySQL to PostgreSQL shouldn’t be considered a major change in career. Searching certain stability in the tools you use should be seen as good move.

We developers love to stress the part of learning everyday something new and constantly challenge ourselves, but that should be taken also in perspective with allowing time to breathe. We’ve created a lot of pressure on ourselves in terms of having to be constantly pushing with new ideas, investigating in side projects and devoting ourselves 100% of the time to software. That’s not only not realistic. It’s not good.

You only have to breathe.  And just worry on doing a good work and enjoy learning.

Visual Programming and Mental Constructs


I saw yesterday live the Apple keynote on the WWDC. I am far from an Apple developer, but I use OS X and iOS everyday, and I’m interested on new stuff. There was a full section devoted to developers, which is great (well, it’s supposed to be a developer’s conference, after all), and, arguably, the most interesting stuff on that part (for a developer’s perspective) was the release of a new programming language, Swift.

It was announced with an (irrelevant) comparison with Python in terms of speed (I actually have plans to write a post about “why Python is not really slow“, but I digress), as well as a lot of other details that (IMO) are completely pointless in terms of what makes a good or bad programming language.

Most pointless benchmark ever

Most pointless benchmark ever

I am generally skeptic about the announcement of new languages. Almost as much as new web frameworks. Sure, it adds a new flavour, but I’m not that sure about real advancement in tech. Creating a new language, full with proper “clean and beautiful” syntax is not really that difficult. The difficult part is to create a vibrant community behind it, one that loves the language and works to expand it, to push the boundaries of current tech, to make amazing applications and tools, to convince other developers to use it and to carry on the torch. The target of a language are developers. “End customers” couldn’t care less about how the guts of their products are done. “Ruby sharp? Whatever, I just need that it help us increase our sales

Interestingly enough, languages get a lot of character from their communities, as they embed their values on the relevant modules and tools. A great example of that is “The Zen Of Python“. There’s nothing there about whitespaces, list comprehensions or classes, but it reflects a lot of the ideas that are common on the Python world, values of the Python Community. Using a language is not just writing code, but also interacting with other developers, directly or even just reading the documents and using the APIs.

As mandatory as honor

As mandatory as honor

Obviously, Apple is a very special situation, as it can force developers to use whatever they like for their platform. Hey, they managed to create an Objective-C ecosystem out from nowhere, which is impressive. For what is worth, they can even tailor a language for their platform, and not to worry about anything else. iOS is a platform big enough for devs to have to learn the language and official IDE and use it. And I am pretty sure that in this case it will be an improvement over the previous environment.

But the one part that I am most skeptic about is the “visual programming” stuff. One of the “wow” announcements was the possibility of creating “playgrounds”, to show interactively the results of the code. That means that, for example, a loaded image will be available, or that a graph can be displayed showing the results of a function. And that’s the part that I’m not really that sure that is interesting or relevant at all.

Does it look cool? Absolutely. May it be interesting once in a while? Sure. But I think that’s the kind of process that, in day to day operation, is not really that useful in most kinds of programming.

Programming, more than anything else, is creating a mental image of code. Code can be a very complex thing. Especially on a big application. But normally we don’t need to keep the whole code in our mind. We only have to keep certain parts of it, allowing to focus in a problem at a time. That’s the main principle behind modules, classes and other abstractions. I can use OS calls to open a file, to draw some pixels on the screen, or to make a call to a remote server. All of that without having to worry about file systems, graphic drivers or network protocols. And I can also use higher level modules to search on files, create 3d models or make HTTPS calls.

And the amazing power of programming is that you are coding on the shoulders of giants. And on the shoulders of regular people. And on the shoulders of your co-workers. And on your own shoulders. That’s a lot of shoulders combined.

But a lot of that process deals with the unavoidable complexity of the interaction. And being able to move from an abstracted view to a more specific one, to look inside and outside the black box, is crucial. It may not be evident, but the mental process of programming deals a lot with that sudden change in perspective. This is one of the reasons of multiparadigm being a useful thing. Because you can move between different abstractions and levels, using the proper one on each case (especially for leaky ones).

And there are lots of those processes that are not easily represented with graphs or images. They are constructs on your mind: loops, flexible structures, intuitions on the weak points of an algorithm, variables changing values, corner cases… Showing all intermediate results may be detrimental to that quick change in perspective. Too much information.

There has been experiments with visual programming, trying to represent code as visual blocks in one way or another, since a long time ago (at least 25 years). They are useful in certain areas, but they are far from a general solution. There are also interactive notepads to allow easy display of graphs and help with the interactivity. iPython Notebook is an excellent example (and a very similar idea to the playground). But, again, I feel that those are specialised tools, not something that is that useful in most programming contexts.

I’m just skeptic. All of this doesn’t necessarily means that Swift is bad, or that those tools are wrong. Maybe the new X-Code will have a lot of amazing tools that will help create fantastic applications (I still don’t like IDEs, though). There are already people checking the docs and giving a try to the new language.  But I think that it has to show up how good or bad it is for itself, and by the developers that decide to use it. So far, it is just an announcement. I just feel that most that was said on the keynote was not relevant to determine whether it’s a good working environment or not, but was just a gimmick. Yes, obviously these kind of announcements are publicity stunts, but in this particular case it looks especially so.

Looks cool, but is not particularly relevant to how the mental process of programming works or what makes a language good.

Hmph. Visual blocks. Heh. Excitement. Heh. A Developer craves not these things.

The amazing forgiveness of software


One of the things I like most about developing software is the fact that you can recover from most mistakes with very few long term impact.

Bugs are unavoidable, and most of the people involved on programming deeply understands that is something we all live with.  So,  there’s no hard feelings, once you find a bug, you fix it and immediately move on. Not only no one thinks that you’re a bad developer because you write bugs, but typically the impact of a bug is not that problematic.

Yes, there are some bugs that are just terrible. And there’s always the risk of losing data or do some catastrophic operation on production. But those are comparatively rare, and with the proper practices, the risk and damage can be reduced. Most on the day to day operation involves mistakes that have a much limited effect. Software development is more about being bold and move fast fixing your mess, than it is to play safe (within limits, of course).

This can affect production data! Show warning sign!

This can affect production data! Display warning sign!

Because the greatness of software is that you can break it on purpose and watch it explode, and then fix that problem. In a controlled environment. Without having to worry about permanent effects or high costs. And a good test is the one that ambushes the code and try to viciously stab it with a poisonous dagger. The one that can hurt. So you know that your system is strong enough against that attack. And then iterate. Quickly. It’s like having a permanent second chance to try again.

Not every aspect of live is that forgiving. I guess that a lot of doctors would love to be able to do the same.

Do you mind if we start the trial again and the jury forgets everything, your honor?

Let your fellow developers know they’re great


I think that one of the most challenging things in my life as a developer is the Impostor Syndrome. Unless you’re stuck into a mediocre job, where everyone around you is pretty lame (and, believe me, if you’re in that situation, you want to get out as soon as possible), I think it is quite common to get that feeling of “wow, I don’t deserve to be here” feeling from time to time.

I am pretty terrible at myself, and I suspect I am not the only one. If I achieve something, that great feeling of “Oh, yeah!” will wear out after a few hours or days. I still remember sometimes failures I did at High School and feel bad about them. Yep, it sucks.

I have also perceived that it’s more dependent on yourself and team dynamics, that really on how smart people surrounding you is. Currently, I am in an astonishing place to work, where there are plenty of super amazing people. Surely I get impressed with great stuff often. But in previous jobs I had, where people were way less awesome but there were less communication, I felt it even worse.

Probably because we are painfully aware of all our limitations, the times we procrastinate, our failures, our own struggles with stuff that’s hard. But we perceive others more as their successes, their external results and their progress. One of the most common advice when performing live is to learn to “keep going” after a mistake, because it’s more important to continue that to allow that mistake to make you lose focus. With lack of positive reinforcement and seeing how valued is your work, it is very difficult to see your achievements and see yourself as a valuable member of a team.

I am more and more convinced that a great team and a great atmosphere are two of the most important things at job (if not THE most important), as well as in life. After all, we want to be reasonably happy while we’re working. Heck, we deserve to be happy at work.

That’s why I consider that giving good feedback to your co-workers is absolutely capital. Of course, when deserved. Of course, honest. It has to come from the heart. But I’m pretty sure that most of developers out there are way more eager to say and mean it “this is crap” than “this is fantastic“. And it shouldn’t be.

One of your most important duties as a developer is to show appreciation to your fellow co-workers so they know they’re great (and you know they are)

Respect Driven Development


I think that one of the most overlooked components on any sane company culture is Respect. That’s probably true also for any relationship, also outside work environment, but I think is usually forgotten when nice places to work are described.

When I look back about the things that bothered me the most, most of them are related to disrespect, even in relatively minor form. It can be personal disrespect or not respecting the work itself or even the customers. Probably because is something engraved, it’s easy to take for granted when it exists, and to identify more problems deviating from the lack of it when is not present. We typically talk about how great cultures are innovative, open, communicative, fun, collaborative, etc. but one of the prerequisites that makes these values worthwhile is Respect, both to your coworkers and to the work itself.

R-E-S-P-E-C-T  Find out what it means to me

R-E-S-P-E-C-T
Find out what it means to me

Without Respect, ideas are accepted mostly depending on who present them, and need to be imposed. Even when there are explicit request for ideas, they take the shape of “suggestion boxes” where no one really looks into them. So, in practice, being proactive is discouraged unless you’re in a power position.

When there is Respect, ideas can be freely exchanged without fear of not being talking seriously. They are also welcomed from any source, not only through the “chosen channels”. There can be hard scrutiny, but it will be fair, and rejections will be reasonably based in facts.

Without Respect, a “funny, relaxed atmosphere” can be easily transformed into harassment and abuse. Jokes will actually hurt. Closed groups,   extremely aggressive with everyone external with them, will be formed. That can include groups outside the company, like mocking customers or partners. Some groups will be appointed as intrinsically “better” (engineers, executives…) as others (secretaries, workers…) and generate asymmetrical relationships, with one part dominating the other.

When there is Respect, jokes are played just for the laugh, and are taken up to the correct limit for everyone, as there are people with thicker skin than others. If those limits happen to be crossed, the problem will be arisen and people will sincerely apologise and correct their behaviours in the future, without external influence. Occasionally the customers or partners can be make fun of, but the quality of the delivered software will be took extremely seriously (the highest form of Respect for customers) and their requests or suggestions will be taken into account when making new features.

Without Respect within the company and the different groups, no particular measures will be enforced to protect anyone or anything. Therefore, it will be easy for someone to take advantage of that, ranging from lower the quality of the work to be a moron and degrade the working environment. Code will devolve into an unreadable mess, and technical debt will grow uncontrollably. Hiring standards will get lower, and not-that-great people will be part of the team (technically, but also in a more personal sense). Also, the expectations will be to work overtime regularly, without any contingency plans or treating it as a bad sign.

When there is Respect, the organisation truly cares about the people, and not just as an empty statement. This includes understanding when overtime is unavoidable evil and work as a team to avoid it as much as possible. And when it happens, everyone do as much as they can to make it as short and enjoyable as possible. There will be understanding when someone wants to leave because they have a genuine different interest, leaving the door open if things don’t turn out for the good. Learning and personal growth will be encouraged with actions, not only with words.

Trust, a extremely important value, can only arise if there is Respect. Without Respect, fear and uncertainty will replace real trust. Being honest needs trust and confidence in the other part, as real honesty can be, and sometimes should be, uncomfortable to hear. Formality and defensiveness take control over honest feedback and team work when respect is not present. Any long-term relationship also needs Respect to stay healthy.

What have I ever done to make you treat me so disrespectfully?

What have I ever done to make you treat me so disrespectfully?

Being imperfect human beings, we cannot probably achieve perfect respectful relationships  at all times. But we should try to be as respectful  as possible, identifying our mistakes and the ones of the organisation, and move up towards the Respect ladder. That makes a much healthier (and happier) environment for all. We should recognise the Real Respect, as the word is often abused.

It is great to aim for having a great organisation or startup, with a thrilling culture. But, in order to get to establish a funny, exciting, learning, diverse and passionate place to work, we should lay strong foundations with Respect. Identify it, and not tolerate the lack of it.
