I started to use ZX2C4’s pass back in 2016 to manage my passwords.
I liked the idea behind pass, but I found it too hackish.
For this reason, I moved to gopass at the end of 2017 because it was a far more complete implementation of pass from my point of view.
gopass is now part of my system, and I’m so used to it that it is hard for me to think about my workflows without gopass into them.

I often see people and companies moving their workloads to the cloud. Speaking with them, they explain that the cloud is cheaper, more flexible, and more reliable than their current infrastructure. To further increase investment return, they often target a specific (single) cloud to reduce management costs and complexity.
By itself, this trend seems a very reasonable one. The risk is that, sometimes, people do not consider the less immediate risks around this move. There are many of those risks, and if there is an appetite for it, I’ll be talking further about the other dangers, but now I would like to focus on a specific one: the risk of a shutdown.

A few years ago, I wrote a blog post on managing CORS headers with Negroni. Lately, I’ve created a new API server that needed to be accessible from the browser, but this time I used a different technology, more precisely gRPC-Gateway.
Few months after I wrote that blog post, I stopped writing new REST services by hand. I did not rewrite all the services that used the old paradigm just because they needed a fix or a new feature, but for all new services, I moved to gRPC with gRPC-Gateway.

Three years passed from the moment the GDPR become binding law in the European Union. On the one hand, I’m happy that it has already been three years, but on the other hand, I’m impatient to see GDPR fully applied.
Cookies are always a hot theme when we talk about GDPR. I still see websites handing out cookies (first and third parties ones) without a cookie banner or to users who have not pressed the “accept” button on the cookie banner. Also, speaking about cookie banners, the majority are not compliant since they often make it hard to refuse cookies or pre-select cookie acceptance. This situation is unfortunate, but we see some movement on this (like the noyb initiative). If those initiatives continue, as I hope, next year, the cookie situation will be much better!

On September 1st, 2020, the maximum lifetime of TLS certificates signed by Public Certificate Authority got reduced to 13 months. How did we arrive here, and what’s to come? Let’s start from understanding who decides the maximum lifetime of certificates and many other limitations around them.
Ultimately, the client (often a browser or an operating system) identifies the certificate as trustable or not (based on the CA that signed it as well as many other parameters), so the client can decide which parameters to look for and which values are acceptable and which are not. This clients’ freedom makes the whole situation very messy since every client can decide their own set, and a subset of the options accepted by every client can be very small if not empty.

As it is becoming a sort of tradition, here we are, after two years from the enactment of GDPR to see how it performs in the real world.
In our previous yearly check, we analyzed the situation from two points of view: the banners and the fines. Let’s see how those two topics have evolved in the last year.
On the 1st of October 2019, with the judgment in case C-673/17, the European Union Court of Justice clarified that pre-ticketed consent checkboxes are not sufficient since the consent has to be expressed actively by the user. This requirement was clear to me since my initial approaches to the GDPR, since it was clear that this was the only way to respect the Regulation’s spirit. Still, it is very nice to see it stated explicitly by the European Union Court of Justice.

Google Cloud provides the capability of terminating a VPN connection with a VPN Gateway. The problem is that the VPN Gateway - at the moment - is relatively limited in capabilities. One of the missing capabilities I would have liked to see implemented is the NAT capability.
VPNs can be used to connect the machines of two different parties. Although this is usually not the best architectural pattern, since a connection on the public internet encrypted at the Transport Layer is often a better option, it’s relatively common in more legacy environments. When a VPN is used in this way, it is very common to incur in an IP space collision, and therefore it becomes required to use some form of NAT. Let’s see how to implement this scenario in Google Cloud without terminating the VPN directly on an instance (which is possible but has its problems, and maybe we’ll be discussing it some point in the future).

In the last few days, multiple fines related to privacy have been announced. More specifically:
Even if I talk about them “collectively”, I would like to point out that the third one is very different in nature, in nature and in the jurisdiction, and therefore in the amount of the fine from the first two, which are fairly similar among them.

A few days ago, Facebook presented Libra, a blockchain-based cryptocurrency project.
After the inception of Bitcoin around ten years ago, we got more and more used to new cryptocurrencies being presented every other day. Often those projects are created by small teams of people, often anonymously. Facebook’s announcement is very different since Facebook is a huge company and has partnered with many other huge companies for this launch.
I’m very skeptical of Libra, and I think it will not succeed in the long run. In fact, it already starts with big challenges, including the fact that most people do not trust Facebook. Differently from many companies, Facebook is used by many people, but it is not generally trusted, and the base requirement for the success of any kind of currency is the trust in the entity behind it. Libra will be managed by the Libra Alliance and not Facebook directly. Still, so far, we have seen a much more significant presence of Facebook than any other Libra Alliance member, so easily Libra will still be referred to as “the Facebook cryptocurrency” many years from now.

One year has passed by the 25/05/2018, the day that the GDPR started to be enforced. Today I’d like to see how this first year of GDPR went and what we could be expecting for the future given what we have seen so far.
The first consideration that I think is obvious but interesting is that the Internet did not close down on the 25/05/2018 as many were worried. In fact, not much changed on that day. A thing that did change a lot is the number of banners asking the authorization to give some cookies to your browser. This increase of cookie banners is an interesting phenomenon since the differences between the EU cookie law and the GDPR on cookies are minor. I think this phenomenon can be explained by the fact that now companies are more worried about violating those regulations than before, thanks to the massive fines that they can incur into with the GDPR.
