2 weeks ago I passed the AWS CSA Professional certification exam. Here are my thoughts hoping they might thelp others who are studying or are planning to earn the certification.

First off to be eligible for the AWS CSA PRO you need to hold a valid, not expired AWS CSA Associate level certification. In my case I got the Associate 2 years ago and it would have expired on Feb 5th 2018.

Both PRO and Associate certifications expire after 2 years. Amazon training will email you a reminder of the expiration roughly 6 months before. In the notification email they will also highlight
all available ugrade paths, or just the name of the recertification exam.

Ieri sera ho finalmente visto Michele Boldrin dal vivo in un incontro sul tema:

"Cambiamo ritmo al paese.
Le cose che servono all’Italia di cui nessun parla
Ridurre le tasse in maniera strutturale?
Quali, quante, come, con quali tempi"

Seguo Boldrin da tempo su noisefromamerika.org e premetto che mi piace il suo modo schietto di spiegare e raccontare le cose, senza il cerchiobottismo di altri figuri che si occupano di economia (politici in primis). Va da sè che uno così non può piacere a tutti, però IMHO è preferibile qualcuno che ti dice le cose in faccia piuttosto di uno che è d'accordo con tutti su tutto e poi quando agisce fa tutt'altro.

Quello che segue è un testo in cui raccolgo i miei pensieri su quanto sentito ieri sera, con la speranza che la forma scritta mi aiuti a ragionarci.

NGINX has had support for dynamic upstream modules for a while in the community distribution and examples abund. I think this is probably one of the clearest I could find.

Finding a similar config for stream proxies turned out to be surprisingly hard, so here I'm sharing my solution in the hope that it can be useful to somebody. Or someone more experienced can point out a better alternative.
In my case my upstream is an ELB which can and will change ip address often so using the static DNS name was not an option.

I am too jumping on the standing desk bandwagon. I first gave it a try using a support on the table and once I felt the benefit (I felt more creative and focused) I decided to make the move. After all you can still use a standing desk as a normal desk.

I first tried buying one from the usual, US-based, suspects but it can be hard to figure out the cost of shipping and then I'd also have to manage import which has never been too fun the rare times I had to (fyi: you must send a bloody fax. In 2017!).

So I looked around and found some good looking stuff from Italian manifacturers, but the prices are omg!

So I searched Amazon and of course, there it was. It is from a German vendor who is in fact reselling products from Actiforce. I know people using Actiforce and they are happy with it so I bought it.

There are many posts on techniques for testing your logstash config, but I found most of them to lack in the exact details of getting it working and others are just obsolete, so here are my dumbed down notes:
download, unpack and cd into the logstash version you are using or planning to useinstall development tools: ./bin/logstash-plugin install --developmentcheck if the bin directory contains an rspec file. If not create it and make it executable using this sourcenow cd into the project holding your logstash configs. I'll assume your logstash config lives in a conf.d directory: create a spec directory at the same level or run ${LOGSTASH_HOME}/bin/rspec --init for rspec to create its directory structure. You should now have conf.d and spec at the same levelin spec drop a test specification, like the one belowtest your specs with the following command:${LOGSTASH_HOME}/bin/rspec
Enjoy :-)

Edited on Jan 29th 2017 as I missed the plugin step. Apparently I had an older version lying ar…

I have never written a review on a conference and this isn't one: this is a brain dump (hence the lack of form and structure) that I quite simply needed to get out here. It might be incomplete, biased or what else: if there is anything that I should know then let me know in the comments. If you think I'm wrong then let me know that too, but please elaborate :-).

Last week I was, for the first time, at Codemotion in Milan. A first time doubly so: I had never been to a generalist conference before. Being I a generalist person I appreciated the format, even though I found some of the technical talks too light on actual details.

The talks that I liked the most were those of the inspirational track. I went to thesetwo among others and I heartly recommend that you watch them (heck, have all your team watch them!). Maybe because I'm old and I have recently realized that people matter more than tools or technologies?
Overall I would rate the conference an 8 out of 10 just for tho…
