Change your DNS to

I have got this news this morning and thought I might share it, hopefully contributing to a more private and faster internet experience. But please, don’t be fooled, the increase in speed won’t be easily observable as we are talking about milliseconds.


Yes. In the networking world when you test networks it is a common practice to send data packets to other computers on the network and measure how long the packet takes to come back.

This test is done through the ping command.

Of course the amount of time that these data packets require is very short and this is why it is measured in milliseconds. As I mentioned above, making this change is not something that will make observable differences to your daily internet experience, still by reading the official data on the homepage dedicated to this project, it seems like the amount of time required for a data packet “to go and come back” is reduced by half, by using the new DNS instead of the widely used google DNS or


From this data it appears that pinging google DNS should take 34.7 ms, while pinging should take 14.8 ms.

This is what made me consider the fact of changing my current setting: for sure we are talking about milliseconds. Still it is half the time I would normally require to have an answer from Google’s DNS.

Really? Let’s try it then!

Changing the DNS settings in your router takes just a few minutes. If you know by heart “where is what” in your router configuration it may take even seconds… or milliseconds! 🙂

Out of curiosity I have performed some tests by using the ping command myself. I let the software send 10 packets and the results show that using instead of as a DNS is circa 35% faster. Not as fast as I first thought, but faster. Here below my test results:

Pinging gets an average of 14.877 ms.
Pinging gets an average of 20.068 ms.

About privacy

But speed is not the only concern.

It seems that DNS, as it is used today, can be used by ISPs to collect information about which pages are visited by whom. Even if the visited pages are securely encrypted and showing the green https:// in the address bar the ISP will still know that you are visiting that page. And, it seems like some ISPs could be tempted of selling this information to other companies for marketing reasons.

As stated on the project homepage Cloudflare and APNIC have teamed up to change this and make sure that by using no IPs will be logged, which will considerably help in respecting the privacy of their users.

Should you be interest on more details regarding the subject you may want to read cloudflare’s blog.


Personally I haven’t had any issues in making the change, also because my network configuration is pretty simple. I have already read that for some countries and with some ISP there are issues as the address has been used for a wide range of scopes which may interfere. If I understood it right though, if you are able to open you should be fine.

Hope you did find the post interesting, feel free to leave a comment, and maybe add your own measurements? 🙂

Heating system: technician advice

After a few months I have finally decided to do something about our heating system which is still showing some pressure loss as I was mentioning already in this previous post.

Past week I asked the plumber company Gino Lepori & figlio SA to pass by and have a look at our expansion vessel (not too sure this is the correct English name) and check it thoroughly. I wasn’t at home to check if he really did it, I’m pretty sure he didn’t like the idea of troubleshooting the whole heating installation as it is pretty big. Still, he told me has checked that expansion vessel and that in his opinion it is still working properly. Therefore he called Elco on my behalf. On Wednesday current week their technician passed by.

Apparently, my burner, belongs to the first ones that were installed and are known for a faulty heater exchanger: if this is the case it is not possible to spot the water spilling out of the burner or leaving tracks somewhere, because the water would go from the heater exchanger where the condensed water therefore there won’t be any chance of noticing it.

What to do?

The plan is following: we will try to separate the water circuit of the burner from the circuit of the floor heating. By doing this we hope to see if the burner looses water pressure. And it should happen quite quickly, as the volume of water contained in the burner is a lot less from that one in the whole heating circuit.

Claudio showed me the steps that I should perform in order to separate the burner circuit from the rest.

Step by step guide: how to isolate the burner water circuit

Turning off the burner

On the right of the burner there is an On/Off switch. Just press it

Closing the pipes bringing water to the burner

There are 4 valves which are very hard to turn. I used some hard surface to protect my fingers while trying to move them in the right direction.

Burner valves
Closing the valves bringing water to the burner. The one on the left is already closed and shows the position of a closed valve.

The valve in middle in yellow color, is the one bringing the gas and doesn’t need to be closed.

Once the water cannot reach the burner, in order to avoid the water pump of the burner to run while empty, it is a good idea to disconnect it.

Disconnecting the water pump

In the burner itself there is the pump which is connected to the power: it is sufficient to remove the cable in order to interrupt the power supply.

This picture shows on the left the power connector which should be removed in order to interrupt the power supply to the pump

Once those operations are completed it is possible to start the burner again and check how the water pressure behaves. Shouldn’t there be any issue it should remain unchanged.

This morning: the first test

I decided to perform the first test this morning before leaving for work, around 08:15. As I entered the room I realized that the burner was running: I checked on the display and apparently it was heating. Also the valve for the heating was on. I mean we are in June, the heating is turned off, why did it start? It is true that in these days it is raining a lot, temperature have dropped, but outside there still are like 15°C while inside we still have a lot of warmth, still from the passed days, which were really hot. Anyhow, this will be next issue to be checked. I decided to do what I was told, therefore I executed each step as described above.

… and the first results

Which I don’t believe too much. The burner acted strangely, maybe because it had been heating until that moment. Anyhow, as soon as I had separated it from the rest of the heating circuit, the pressure dropped reaching very quickly 0.

Water pressure drop
As I switched the burner back on, after having closed the valves, the pressure dropped to 0.6 and after to 0.

Strange behaviour

The burner didn’t act like that when I tried together with Claudio, the Elco technician: in that case the pressure was stable at 1.6 bar. I guess that this happened because at the time it wasn’t heating.

What’s next?

I’m going to set the burner back to normality and try again. Meanwhile I’ll notify Claudio and see what he thinks about it. I believe that already the first, sudden pressure drop is already something which is showing a problem.

Traces of a huge (animal) party!

Lugano is waking up: slowly though. Seems like today is going to be a beautiful day!

Beside the magic my curiosity was taken by some intriguing signs in the snow: it really looked like someone had a party on the balcony.

What happened on this balcony? Someone had a party?

I was so curious I decided to adventure myself in the cold and have a closer look! What kind of animal might it be?


This is another animal though… a crazy one!

So I decided to go have a walk in the nearby woods and have a look for similar traces! Hereunder a sequence of pictures! Sadly it is not possible, at least for me, to recognise any specific animal since the snow was already partially melt and the traces were not as definite anymore! Still, perhaps the first picture, is quite definite! Was that a cat or… something else?

Alcune settimane fa abbiamo in palestra ci siamo esercitati in questa maniera. La sequenza mi è piaciuta molto perché semplice da ricordare e perché non richiede alcun attrezzo se non un tappetino.

Riscaldamento è stato eseguito facendo il “lombrico“, posizione “squat fermo” e “gatto con ginocchia sollevate da terra”.

Successivamente è iniziata la sequenza, eseguita in questo ordine:

  • 15 sqwat
  • 10 addominali
  • 5 flessioni

Tutti e tre gli esercizi devono essere completati entro due minuti di tempo: chi finisce prima potrà usare il tempo che avanza per riprendere fiato: la sequenza va ripetuta 8 volte. 

Il tutto entro due minuti, se finisci prima, il tempo che avanza è pausa. Ripetere 8 volte.

Riuscendo a fare questi esercizi in praticamente 20 minuti si è già sudati, con il fiatone e pronti per la doccia!

Mi spiace per il post molto specifico e poco comprensibile per chi non esegue gli stessi esercizi o frequenta la nostra palestra, ma in questo caso ho deciso di scrivere proprio per poter ricordare la struttura dell’esercitazione più che per condividerla.
