Receiving Linkedin invitations to connect is the most common action you do on the work-oriented social network. So frequent, that I know quite some people that simply pile up dozens, then hundreds of invitations, not wanting to accept them. The reason is usually the same: It's a recruiter that either didn't even sent a private message to introduce himself/herself, or that if they did... it smells like a template filled just with your name and as much as your current company name.
This is sad, because I really believe in the power of Linkedin as a source of good talent, but so much noise and flood of low (or no) effort recruiting attempts, sometimes even blind shooting (or worse, receiving similar messages from multiple people of the same company's HR department) just creates an ugly picture of the recruitment job. And while I also suffer them from time to time, I've also had pleasant experiences, both regarding job changes and just having good chats explaining my situation and reasoning to not wanting to switch job.
But there's also a part of me that is a bit paranoid regarding privacy, so since long ago I found what I think is the single most interesting privacy option at linkedin: Changing your connections list privacy to private. Or more especifically, changing it so your contacts will only see those of your connections that are shared, that they also have on their contact list. This is not only a good defense line to keep your contact lists private, but also a bit of a trolling mechanism for those lazy recruiters who don't do their homework: "sure, you want us to connect so you can try stealing or spamming my contact list? No problem, but there's a surprise waiting for you". It also is interesting if at your job you have some referal prizes, which can sound selfish but I've seen HR departments prey every employee Linkedin hunting for fresh meat, and then annoy some people from multiple sources almost at once.
This handy option can be found under Privacy & Settings:
As I said, it is not always the case and there are good recruiters too (I've met a few), but the market is saturated with unprofessional people and this helps to keep them at bay, or at least frustrate their attempts of grabbing your connections.
We sometimes are too negative and forget that many times there's also a bright side about most situations. For example, when we don't end nicely a work relationship, we tend to only remember what went wrong (if it did, that is). This post is a small recapitulation of good things I've learned on each and every past job, no matter if it was overall a good experience or not.
At my first job, Eidos (now Alhambra-Eidos, and NOT the videogame publisher) I had the luck of directly learning a good way to build software: 3-layer applications, separation of web templates and code, SQL Server stored procedures instead of SQL in strings, distributed components... They also hosted for free one of my defunct websites for many years.
At the second job, Surfernet, I did some of the coolest projects: A full MSN Messenger client from scratch (fully implemented the protocol), a Winamp-like MP3 player, and other nice applications with fancy graphics using Win32 API. It was physically exhausting (I worked from 8AM to 1PM, + going to university until 9PM) and schedule was always tight (usually projects took 1,2 months max.) but I learned a lot.
At the third job, I mostly developed the sense of teamwork. Development was a tiny fraction of the company and not well cared about, but the four of us took the daily job with tons of humor and smiles up to the day we left.
ilitia was the 4th job, and I lasted there for 4 years. On one side, it was a job where I matured a lot: Long times in a client, dozens of projects built in quite varied languages ranging ANSI C to advanced C# (.NET Remoting, threading in the pre-C# 2.0 era, ...), first time ever doing testing (even TDD!), setting up a .NET continuous integration server, my first usergroup and event talks (giving the first one in front of 200 geeks was really scary), even managing a small team of two people in my last months... On the other side, lots and lots of fond memories, parties, friends made (some of my best ones come from here).
Then came NAVTEQ, an important milestone because I got out of consulting. I learned to fight for what I think it is right, whenever it is the appropiate programming language (instead of a random management decision), pushing for rewriting components, or daring to peek into heavy algorithms-related code (I optimized an A* component). It was also the first time I had to talk in english at work but outside of events/talks.
Nokia shutdown NAVTEQ Madrid offices, and I ended up hired at Tuenti, another place where I've been almost 4 years. Here I got way out of my comfort zone, switching from a full .NET stack to a LAMP one (but hey, at least was object oriented PHP!). By far, Tuenti is the place where I've learned most and quickest, pacing being so fast that we joked about 6 months there being like 2 years at any other company. Lots of high scalability concepts, watching a website grow to millions of users and huge numbers of visits. It was a monolith but it worked nice and we were better than Facebook in Spain for quite some time. The "work hard, party hard" motto was 200% true, but I would repeat the experience without a doubt.
Minijuegos was the seventh job. Wanting to go back down to building big chunks of something from scratch (or almost) I joined. Between three people (CTO, a junior dev and me) we were able to fully build an online games portal, avatar generation system, CMS, APIs, payment gateways... I was able to put into practice theory learned in the past, work with asynchronous jobs... and work for once in something related with videogames! (my childhood dream). Things slowed down and tasks weren't so challenging but I did my "Mr. Wolf" role, got "version 1.0" done and made some good friends there too.
CartoDB (Vizzuality in 2014) was another radical shift, ditching my PHP and MySQL knowledge to start with Ruby (on and off Rails) and PostgreSQL, and this time moving to a full backend engineer role. There I learned a lot about databases, importing big amounts of data, manipulation and transformation of data, heavy DB-related operations, developing and maintaining APIs, and lots of interesting concepts of mapping and GIS (although I only grasped that world). I'm happy because I think I was able to hold up with a big part of the backend, alone for a while and then with some great colleages once we grew.
And now, The Motion marks the 9th job. I have lost sight of my comfort zone: now I'm working with Python, microservices, containers, AWS, managing a small team... And getting for once deep into devops tasks... We'll see how it goes ;)
Last month I forgot to post anything so here comes one of the books I read some weeks ago, Speccy Nation. Small, cheap and not especially good, but hey, I paid less than 2€ for it so what could I expect...
Title: Speccy Nation
Author: Dan Whitehead
A small 124 pages B&W book about 50 ZX Spectrum games chosen from a British perspective. Nothing less, nothing more. Some are terrible games (chosen on purpose), some are really good classic ones, but I really miss international games, as for example Spain had lots of really good titles.
The writing is good, even in the case of really straightforward and even simple titles, knowing when to simply explain how the game worked and when to expand with what made it really different from others.
Some chapters about the Spectrum itself or its history would have been welcomed, but we get exactly what we're told about. The description of games vary in length, some being a bit small (1 page including a screenshot) others being 2 pages long, sometimes they feel not extense enough and in a few cases you don't even get to know exactly how the game was played, but is the exception, not the norm.
Overall, a really cheap title so if you feel nostalgic is a good quick read to maybe grab ideas of some games to play (if you're able to get them).
Last weeked I found some spam at two of my BlogEngine.NET blogs. It is not the first time, and in the past updating to the latest major solved the issue, but this time I had to switch from 2.9.X to 3.2, and I already suffered a migration from 1.9 to 2.0 that gave quite some headaches. One of my main reasons to go far away from Wordpress was to stop this tiring battle between spammers and new versions, that forced you to update way too frequently or face serious security bugs and spam-holes. Combine that with a general feeling of being tired of big, admin-driven blog engines, and I needed a big change.
My premises were:
Reading some articles and checking some static generators, I found Pelican. I peeked at bit at the source code, documentation and plugins, and it looked quite simple. Did some local tests, wrote some posts using existing content and read the documentation, and decided to keep it.
The setup is so easy I got a blog running locally with some base theme in a few minutes. But I had one issue, all my posts are in XMLs (thankfully I had chosen not to use a DB for storage) and Pelican uses Markdown... so I had to transform the data somehow.
I don't do too complex stuff like
<meta> keywords and I set some post tags but not even show them, so in general I just needed a few fields for the pelican post format:
Title: ... Slug: ... Date: ... Tags: ...,...
...CONTENT (which can be directly HTML)...
The XML has a very simple structure, with all the fields and just HTML-encoded the content, some regular expression searches and reverse transformations were enough to port everything. I have plans to migrate another blog, and prefer to be able to reproduce the whole migration any number of times, I built a small script. It only handles basic stuff and doesn't extracts other "basic" fields like authors, and only works with posts (I manually migrated the pages as I had few), but it does what it does well and might be of some use to somebody else.
You can find both my scripts and a small plugin (to limit RSS/Atom syndication feed output to only a certain amount of items, as by default dumps every post ever written) at my GitHub.
I'll probably work on more small plugins in the future, as I have some improvement ideas regarding output content generated, but I can't be happier with the results. A proper example of "the Python way of life", simple yet practical code, easy to setup and use and does it's job without many features.
UPDATE: Added another small script to GitHub to do some post-generation tasks like creating duplicates (as "aliases") and moving or removing certain files from the output folder.
Due to my new job I wanted to learn about microservices, and this book had good reputation and recommendations, so I decided to read it. After finishing the read yesterday, I can only recommend it to anyone starting with this system design principles.
Title: Building Microservices
Author: Sam Newman
I'm pretty new to microservices, but working in a startup means you usually have to ramp-up from not knowing something to being able to use it on a daily basis, and quickly. While I have an experienced colleage in the subject, I cannot be asking him always, so I grabbed this book based on some recommendations, and have been reading it& on commute time. And spoiling the review, I definetly think it is worth it.
I come from& a background of classic monolithic web-apps, a SOA platform and a mostly shared-codebase set of REST APIs and components, so for me it's a process of true discovery and mindset revolution to think in really small, bounded and clearly defined services. It is too easy to cross those limits and do more things in the same place, or by mistake create dependencies or couplings. One of the first services I built few months ago acts really as a distributed synchronous component, not honouring the microservices "autonomous" principle... So I have a lot to learn, but this book really has taught me how to do things better.
Always including real world scenarios and stories from the author, we're slowly introduced to the basic pillars of a microservices architecture, to the why, what and how to both build from scratch and separate existing systems into pieces, decorated with lots of advices and curiously not so many dogmas, but tips and "usual solutions" (but not mandatory) about approaches you can take. I like the fact that many books speak about "universal truths" where here the tone is more like "decide by yourself and take my advice as guidance".
Moving towards asynchronous processing and communications, how to handle code reuse, libraries and shared components, orchestation (or why is it good to avoid it), metrics, monitoring, cross-functional requirements, testing, deployment, security, scaling... There are so many concepts at first that the last chapter of the book is a "quick" summary that I think we should print and leave at the office as our small "microservices builder manual".
I had been told about some of the concepts, thought about few ones (but as usually happens with design patterns, not exactly in the best way) but the book provides lots of proper namings and topics you then can read more specifically about (like caching for resilience, synthetic transactions, consumer-driven contracts...).
I could go on longer, but I'd summarize it as a must read book if you work with microservices. Highly recommended.
