I cancelled my Amazon Prime subscription

I was using a lot Amazon. Sending parcels to my previous job offices, and now to Blizzard offices, so I subscribed to Amazon Prime. With COVID-19 virus we were sent to do Remote Work, and now with the lock down basically I’m 99.99% of the time at home.

I did a test to see how it works sending to home during the pandemic.

I choose two different items, I reviews the order, they were going to be delivered separately, one day of distance.

I choose two items that will fit in my mailbox, separated or together. One USB3 3mts male female and a Blu-ray movie.

My surprise comes when I go to the mailbox one day before and I see that I have a paper from an-post telling that they pass by to deliver my parcel, and they did not leave because it doesn’t fit the mailbox and they did not want to leave it a common space. For my surprise both Amazon parcels were grouped and sent before time. Maybe in a bigger box. But the mailman did not ring my door.

The paper tells me to get my parcel in the middle of the city, during the lock down. No way! I’m not going to risk my health and specially from elders, just to grab a cable and a movie.

I had the chance to request re-delivery to an Post, so I do. I fill all the info, I inform my phone number, email, I indicate which door to ring, and two days after as promised… a paper from an Post!.

They did not even rang my bell again.

I go to Amazon to cancel the order, but the process is only created for if you got the items.

Fuck it. I’m not going to order anything else to Amazon until that COVID-19 passes.

I don’t know if the postman just avoids people for fear to contagion or the process of an Post is awful and he didn’t get any information. But I’ll not buy anything even if I cannot buy in other places cause the lock down.

I was going to maintain my Amazon Prime subscription, even if I know that I’ll not use it much with the lock down, but makes no sense. Also:

  • I use Netflix and my Raspberry Pi 4, I was not using Amazon Prime Video.
  • I use Spotify, I was not using Amazon Prime Music.
  • I like to read in paper, not in eBook, so I was not using the eReader options.

A nice way to loss a customer.

Datacenters, D&R and coronavirus

I’ve been working for years within Data centers, with D&R strategies, and then in the middle of COVID-19, with huge demands on increments of bandwidth and compute, some DCs decided to do not allow in the Engineers of their customers.

As somebody that had my own Startup and CSP and had infrastructure in DCs and servers from customers in colocation, and has replaced Hw components at 1AM, replaced drives from broken RAIDs, and fixed systems so many times inside so many Datacenters across the world, I’m shocked about that.

I understand health reasons can be argued, but I still have Servers in Datacenters because we all believed they were the most safe place, prepared for disaster and recovery, with security, 24×7… and now, one realise that cannot enter to fix or upgrade the own machines.
Please note, still you can use the remote hands from the DC, although this is not a good idea many times, I’m not sure this will still be an available option when the lock down in those countries becomes more strict.

I’m wondering if DCs current model have any future at all.

I think most of the D&R strategies from now will be in the cloud, in different regions, with different providers, so companies can resist providers or governments letting them down.

Blocking some offending Ip’s easily with Ubuntu ufw

Ok, so we know that there are several ip’s that have attempted to hack the blog.

We know they try different urls looking for a exploit, or they try to hack a password by brute force…

We are using Amazon EC2 and the old infrastructure, not a VPC Network, so we cannot block a specific Ip to our Web Server.

In an article from 2015 I explained How to Stop a BitTorrent based DDoS attack, and was using iptables for that.

In this example I will show how to use ufw to block tow specific Ip’s, execute as root or with sudo:

ufw insert 1 deny from to any
ufw insert 2 deny from to any
ufw allow OpenSSH
ufw allow 22/tcp
ufw allow "Apache Full"
ufw enable
ufw status numbered

You can do ufw status numbered to see the status of ufw and the rules order.

root@ip-111-111-111-111:/home/ubuntu# ufw status numbered
Status: active
To Action From
-- ------ ----

[ 1] Anywhere DENY IN
[ 2] Anywhere DENY IN
[ 3] Apache Full ALLOW IN Anywhere
[ 4] OpenSSH ALLOW IN Anywhere
[ 5] 22/tcp ALLOW IN Anywhere
[ 6] Apache Full (v6) ALLOW IN Anywhere (v6)
[ 7] OpenSSH (v6) ALLOW IN Anywhere (v6)
[ 8] 22/tcp (v6) ALLOW IN Anywhere (v6)

If you need to delete a rule, use the number on the left and, just type:

sudo ufw delete 2

Making responsive WordPress Theme Twenty Twelve to support greater resolutions

This is the first article I write about FrontEnd in here, as this is very casual and trivial, and I wanted to specialize the blog in Extreme IT, going deep into knowledge and difficult questions. And in any case, more for BackEnd, Engineering, and Hardware and Operations.

But as it is something useful and myself didn’t found an answer when I googled it, I think is no bad to share it here. Nevertheless I’ll not make it appear in the front page to be loyal to my essence.

So I like Twenty Twelve WP Theme. It’s clear, that’s what I expect from a blog from an Engineer: easy to read. Maybe is to Spartan, but that’s grant.

The instructions to do like me:

  1. Make a copy of your original Twenty Twelve Theme in another directory, at the same level
  2. Edit the file /var/www/
  3. Add a new section like this

So I defined a new @media screen with min-width of 1800px.

Why 1800px and not 1920px like Full Hd?. Because Ubuntu use some width for the lateral bar.

Then over body .site section I set a max-width: 1800px that will do the trick for some browsers, and the rem value that will do the trick for Chrome.

Now the main section of the block can be correctly displayed using most of the space available.

Media Player in my Raspberry Pi 4

Just installed a media player in my Raspberry Pi 4

So I mentioned it was one of my pending tasks, to do while I’m confined here, at home, to help the Irish government to stop the quick spread of the coronavirus.

I’m happy that the situation in Ireland has stabilized, unlikely in Spain, where that historical lack of discipline and selfishness and super ego to believe Madrid the capital of the world, and so deciding not to close it for quarantine, will cause a lot of pain. I hope the closing of frontiers in Catalonia works.

Well, what I do you’re probably asking yourself, so I installed LibreELEC

They have a very nice SD image writer for Linux, Mac and Windows, that will install the proper image on the micro-SD for your ARM device.

This Raspberry Pi 4 comes with Wifi integrated and a Gigabit Ethernet network port.

When I was in Barcelona, I had Kodi with Raspberry pi 2 and version 3.

This model v. 4 is much more cooler. I bought the 4GB version, and has 2xHDMI 4K.

So it is great to connect to any modern TV.

In Barcelona, I have Linux tower as NFS Server sharing my files with the Pi. Work good, even for the 100Mbit NIC of the version 3, but at that time I was only playing Full HD as the Pi didn’t supported greater resolution, and I only had that resolution on my displays too.

For now, I’m going to explore how is reading from a USB 3.0. Let’s see if it’s able to play smoothly.

The cool thing also is that I have SSH access, and so I can use the Pi for many more things. :)

I have my first update, I noticed that copying to that USB was not the best for me, as I tried to copy a .MKV file of 4.9GB and I encountered the limit of 4GB of FAT32. I could format the USB as ext4, but what I did is, SSH into the box, I see that I have two partitions on the SD for booting the Pi, the second one is a ext4 called storage. So I copied to the SD, through the network, using sftp the file I wanted.

The Gigabit connection was fast, but when the buffer fulled it started to show the real speed of the SD which is 15MB/s for writing.

Ext4 has no problem in holding a file 4.9GB so I’m watching my movie now. Will think about setting a NFS for the Pi as it will be very convenient. :)

I have an external, remote, keyboard logitech, but it happens that LibreELEC recognizes my Sony command, from the television. I don’t need the keyboard/mouse. Nice.

Here you can see my Raspberry Pi 4, connected to TV, in “combat mode”, naked, as PoC, before setting in its definitive place behind the TV.

Playing from the external USB 3.0 stick was also fluid, allowing 4K perfectly.

The only problem I has was when I was pushing movies to the USB through the network, and playing at the same time from the SD. It seems like the Raspberry reached its limits doing this and playing stuck frequently.

Remote working is here

So remote working is here.

After years in which many Engineers requested to the companies to be able to Remote Work, with most of answers No, now it happens that not only is good for the company, is the only way to ensure continuity of business, of many businesses.

One of my colleagues from Denmark, which government has shutdown the country by sending all the public servants to home, in order to prevent the spread of the coronavirus, told me:

“Yes, remote working is here, but has been necessary the four horsemen of the apocalypse”

It is curious, how Remote Working has arrived, no thanks to that was obvious, but due to external emergencies. And I’m glad that my company was prepared for business continuity.

I’ll be staying home, working remotely, in order to contribute to non-spreading the virus, specially among old people. I’m perfectly healthy but that’s a use case, many people will not develop the symptoms and still be able to spread to others.

So I have some plans related to technology to do at home, including few improvements to the blog. What are your plans?.

Update: 2020-03-13 23:16 UTC I’m thinking in all those business which are forces to close, and all the employees that will not get a salary, or will be fired, or will get a salary and the business owner maybe ends in bankrupt as is paying the salaries and no income is being generated.

Update: 2020-03-19 10:58 UTC Some of my friends, even in Human Resources/Recruiting, are starting to remote work for first time. So here is some advice:

I would recommend to get an external monitor, at least 22″, so you neck is not forcing position looking low and your eyes don’t suffer, good light (don’t in dark), a nespresso can be a good friend in the morning, and to have your hands and arms aligned correctly so you don’t suffer from a bad position. Watch the position of the wrists, your arms should be comfortably at the same level than the table, similar in an L, and your eyes be aligned to the top of your monitor. Finally I would recommend to follow a routine, like if you were going to work, so dress like you would do. Don’t stay at home all day in pijamas! ;)

News for the blog, upwards and onwards

2020-03-06 Heya, I’m doing a set of improvements to the blog.

One, you can already see. I added a new section to the CSS @media, so now screens bigger than 1,800 px in width, will use that width for rendering the page. The original WordPress theme at 960x was too small for our current screens. I will add a new CSS @media for 4K screens promptly.

Other is about the organization of the content. I want to separate a bit the contents, now articles are sequential and is difficult to discover nice contents if they have 2 or more articles more recent, so I will group articles by content and provide a small index on the top page. Also I will provide more areas for Operations, SRE, where it will be easy to locate code, scripts, tricks… things that are useful to our day to day. I also want to make visible the articles about living in different cities, for IT Engineers, with useful tricks and tips. And keep the more complex and more interesting Engineering matters in the main page.


2020-03-13 15:49 Added SSL to the blog

With more delay I wanted, I bought a SSL certificate, configured Apache, and after few changes to the blog has been set. One very annoying is that WordPress linked the images statically pointing to so I changed the latest article’s images to point to relative path so they will work nice with http or https.

My reflection is that everything negative can have its positive output. With this coronavirus thing, I decided to focus into improving things. And so I’m doing. :)

Working in Barcelona, Catalonia, for IT Engineers

Created in: 2020-02-20 by Carles Mateo Last Updated: 2020-03-13 19:29 UTC

Note: This document is under construction

Society, Politics and laws

Barcelona is the capital of Catalonia, a Nation with a strong desire of freedom, that wants to get the independence from Spain (which invaded militarily in 1714 and bombed the city many times). Catalans are very different in small villages and in the city center, but me as Catalan, I think that we are nice but reserved, because we are used to be prosecuted just for being Catalans, so we people don’t earn our trust easily. However, if you make a Catalan friend, our loyalty is like family. This is related since medieval books already.

When we suffered the Spanish invasion in 1714, and later the invasion of dictator Franco with the help of Hitler and Mussolini, the Catalan language was forbidden, prosecuted, universities closed, Catalan Constitution removed, Parliament closed… but part of the freedom was recovered in 1975 when the fascist dictator Franco died. Most of the Catalan particularities were forced into assimilation to the Spanish model, however one interesting thing that was not changed was the Civil Right. That’s very important cause some laws survived and are different from the Spanish laws, and from most of the places in the world. One worth to mention is that our Civil Law gives us “Separation of Goods” (separacio de bens), and that means, that if two people marry and one has 3 houses and €20,000 in the bank, and the other has €500 in the bank and nothing else, if they divorce, they’ll get exactly what they had. So individual A will keep their 3 houses and €20,000 and B €500. This is very different from the “Earning Goods” (bienes gananciales) in Spain, where if they divorce A and B would get exactly half of everything. When they get married is like everything goes to the common pool.

Must say that there are details, like if the partner leaves the job in order of take care of the house, they may get something in compensation, or if there are children, at least one house will be for the mother if taking care of the children, and the father will have to pay a pension to feed and take care of the children. Still, it seems to me much more fair that what I saw in most of the countries (even if in some they have pre-marital contracts).

The Catalan society is hard worker and loves to read and to study. Compared often to the Jews, as an insult, by the fascist authorities in Spain during the dictator.

One show of the passion for reading can be manifested by Sant Jordi’s celebration, the 23th of April, which is a day in which girls gift a book to the men, and men gift a rose to the women they love, or they family or female friends.

The Castellers or Human Towers are declared World Heritage and have been present in many international celebrations like Olympic Games.

And the traditional parties in the villages have many books talking about them and are epic.

As Catholics, it is typical to have “el pesebre”, a recreation of the birth of Jesus, but our irreducible character have has to have particular elements like “el Caganer”, which have became world wide famous few years ago.

Pesebre de Nadal

The love for Freedom and the defense of Human Rights has been a characteristic tread of the Catalan culture since it’s origins, around the year 8th Century and the first bilingual dictionary known is Catalan-German German-Catalan. Catalans also invented the navigation code for ships that became universally accepted. Probably this loves for Freedom is what makes Barcelona and Catalonia a place full of entrepreneurs and small business owners. It is said that “Catalans, from the rocks they make bread” (els Catalans de les pedres en fan pans) about the inventive we have to detect opportunities where others see nothing.

The 11th September is the national day, and is the day the Catalans remember that they fight to the end for their freedom that 1714, alone, against Spain and France troops. That day every year, there are many cultural acts, and there is a demonstration for Independence that some years got to 2 Million people, from a total population of 7,5 Million. You can visit parts of the city where there are still holes in the walls from the different times Barcelona has been bombed, at different ages, from Romanic era to 20th century.


The weather in Barcelona use to be excellent. Sun is present from 7 in the morning to 20:00 almost all the year, and specially in June, July and August, people enjoy the beach.

It has a weather similar to California.

It rarely snows, but if you go to the North, near Pirineus montains, you can see snow in winter.

Even if weather use to be excellent, with no wind at all, and few frequent rain, must be said that when it rains it rains. Rain can last 4 hours and more, and be very intense. Very often the semaphores (traffic lights) stop working in Barcelona when it rains.

The city

The city is very well designed with most of it being square islands similar in size. Is easy to drive as every street is two ways and you can go back by just turning right right right right or left left left left.

With a beautiful architecture thanks to genius like Gaudi, or Dali (both put in jail for talking Catalan at different times) .

Sants street is the longest commerce way, in Europe they say, created by many small commercial stores. Many of them have been bought or replaced by Chinese, as the traditional owners could not afford the more and more higher rents for commercial locals in Barcelona. Still many resist.


The city has buses, metro, taxis, tram, bicycles that you can use paying a yearly sum.

Huber was forbidden by the Spanish government.

Taxis in Barcelona are very characteristics, all the same color, black and yellow. In the airport there is an official taxi stop, so don’t get to any random guy that asks you if you want a taxi. The taxi drivers are in a specific place and they will not go to you, as they expect you to go to them.

In the city you can stop a taxi just by raising your hand horizontally, but only the cars with a green light turned on are available, the other have a customer inside and will not stop.


Local food

One typical food. “La calçotada”. Which is a social party, normally for lunch where we eat scallion/spring onions and meat cooked at the fire on the barbecue. We peel the external layers, and eat with a sauce called “romesco”.

Calçots, scallions grilled at the barbequeu
Butifarra d’ou (egg sausage, to eat like that)




airbnb and hotels price

The controversial mayoress has forbidden airbnb in Barcelona. It is only allowed to red a room, but not the entire flat.

Hotels prices range from €110 to €175 per night, except when the city is full and prices double or triple. For example for the Mobile World Congress.

Price of the rent

In the recent years rent has increased a lot.

In the year 2020 a flat with furniture, 5 years old new, 80 square meter in a middle class zone, can cost around €1,200/month.

English and expats

Well, it’s a shame. In Barcelona few people talk a decent English or even understands it.

You better print the address of the places you go to show to the taxi driver.

Salaries for IT

Barcelona is one of the most attractive places in Europe for IT.

A low cost of live compared to major cities like Berlin, London, Edinburgh, Cork or Dublin, and salaries very high for IT, with the excellent weather, a market of 40 millions Spaniards and 7.5 million Catalans (around 10 if we count Catalan speaking zones in the Meditarrean sea).

The minimum inter-professional salary is (updated to Jul 2019) €1,050 net per month.

Salaries for a Senior Software Engineer with 5 years experience will range between €35,000 and €55,000 gross per year. Most of companies provide an optional bonus too.

€55,000 gross per year is approximately €3,267 net per month within 12 payments in a year.


Internet is decent, most areas of the city have Fiber and in some places they have 1 Gbit/s connections.

In some places far from the core of the city only DSL arrives.

Office Material

The paper we use here is Din A4, like in Ireland.

Buying Hardware

Barcelona is full of Hardware stores. There is one street where they are concentrated, is called Sepulveda street.




Dangers/Terror histories/Bad experiences

There are many to tell, I’ve pending explaining seeing thieves in the airport, fake taxi drivers offering their services, pickpocketers in the center, skinheads robbing in the metro… don’t ever leave your belongings unattended.



Those are my recommendations.

La parra

I come here since I was a child

Restaurant and terrace in the Museu d’Historia de Catalunya
Plaça de Pau Vila, 3, 08003 Barcelona
At the top of the Museum of History of Catalonia you can enjoy a restaurant, a coffee bar, and a terrace for having cocktails. The terrace is a cityview where you can see all the port and part of Barcelona. Is very beautiful at nights. There are few tapas bars and pubs and open discos just down next to the Museum’s entrance.

The museum is very interesting too.

1902 Cafe Modernista

Next to the Recinte Modernista Museum, you can have tasty tapas with beautiful views and after going to the museum.

Carrer de Sant Antoni Maria Claret, 167 | Recinte Modernista de Sant Pau, 08025 Barcelona
(st Sant Antoni Maria Claret, 167)

The terrace is owned by the restaurant which is inside, and is very nice, and the menu looks amazing.

Iconic places in Barcelona city

Sagrada Familia from Gaudi.

F.C.B. Football Club Barcelona stadium “Nou Camp”.

Nearby Iconic places

Monserrat, has unique type of rounded mountains. And on top, in the church, there is “la Moreneta” which is a figure of the Mother of Christ, which is black.


Working in Cork, Ireland, for IT Engineers

Created in: 2020-02-20 20:20 by Carles Mateo Last Updated: 2020-03-08 19:15 GMT

Note: This document is under construction

Society, Politics and laws

People are very polite. One nice thing is that you say Bye, thanks to the bus driver when you go down.

The Irish society is very welcoming and also participate a lot in charity. You can see how many people are running in races for a charity cause, and how many commerces collect money for charity causes, from pubs, to supermarkets.

I like the Cork Zombie Walk, where people dress as zombies, ghosts, etc… and walk over the city and finally they go to drink beers and have dinner together. You can volunteer to makeup people and is a very funny experience. Money collected goes to guide dogs for blind people.

They are a very polite society and even in the queue of the supermarket will ask you to any single customer: “how are you?”. At the beginning I was explaining all my life.


The weather is one of the most common form of claims people do. We use to say that we have 4 seasons in a day. It can rain for 15 minutes, be sunny, be windy, snow, be sunny again, rain… 10 times per day!. Although is not very usual that it snows, and heavy wind is neither usual. Rain is really a tiny courtain of water, so I don’t even bother. Having a jumper with a hood is enough.

You can get a top-up prepaid simm for 10 €. It is what I recommend to my American friends and colleagues when they visit Ireland.

The power plugs are like in Scotland and England. So you’ll need a transformer. There are universal ones that costs between 4€ and 10€.

I was surprised to discover that the English talked in the streets, and the practical English, is much more fluid and similar to Catalan grammatically than the official English that the schools teach.

For example, instead of asking: Did you go to the cinema? Is perfectly valid to ask: went to cinema?.

The Irish are very polite, and they respect the physical distance. If they are stood in front of you in the supermarket they will say sorry, and everybody says “Bye, thanks” when going down the bus. From Cork to Dublin you have less than 3 hours driving, I use more as I have a lesion in my back and I stop often, and 3 hours by train. There are also buses connecting Cork and Dublin airport every half an hour almost 24×7. Companies are: and

The Irisih will talk you randomly for no reason at the pub, or at the street. They have good sense of humor, are near, caring, nice and talkative. And they help others.

Once my Visa card failed on the cashier in the supermarket and the man behind me, thinking that I was in trouble, offered to pay my food. That really touched me.

Also another time I entered into the pub with paper bags from the supermarket, and due to the rain, one just crashed and my products when to the floor. One woman in his 65s jump from the chair and came running with a plastic bag “if it’s of any help”, offered it to me. I almost cried. I still keep that small blue bag.

The city

Cork has some of the better universities in Ireland, and in Europe.

So many students from all Ireland come here, and also international students.

The most well known universities for IT are UCC, more focuses on the theory, and CIT, more practical. So seasonally is a stuadent’s city.


Cork has a service of buses that when they work, they work well. Unfortunately often they have to be fixed and you may miss one or two because they did not pass or bass indicating that they’re going for maintenance.

Cork has a train that has good reputation (I’ve not used it), and will bring you to Blackpool, or to Cobh, or to Dublin.

There are long distances buses and that travel to Dublin almost every half an hour during the day or the night.

If you drive at 9AM traffic is terrible, as parents go to drive the kids to the school.

A very convenient app is Free Now, formerly MyTaxi. It will show you in real time where the taxi is, who is, you’ll be able to pay with Visa… Taxis in Cork or Barcelona are not like in the States. They don’t incorporate a monitor so you can see your route, and many taxis also don’t allow to pay with credit card (that happened to me in London too).

Take in count that from 08:30 to 09:30 you will need three times the time required to travel to a destination, as parents bring children to the school and people go to work and the ways collapse.

Also take in count that if you call a taxi using Free Now at those high intervals, maybe nobody will answer your request, or maybe they do and you’ll have to wait 30 minutes. Be advised.

If you are American you can drive legally with your American license for a year, after you’ll have to pass the exam, insurance will be €3,000/year.

Driving: We drive by the right side (as opposite to the wrong side) :)

Driving in the right is like in Scotland. Myself didn’t find it specially difficult but is much more easier renting an automatic car. I do this, and so I don’t have to think about the Gearbox when I travel by the States, or visit Barcelona or other European countries.

There are few automatic cars available. Absolutely the majority of cars in Ireland use manual gear. Don’t ask me why.

If you want to rent a car in the airport it will be around €40 per day, so ~€1,200 per month. I know that you can do good arrangements with small companies up to 650 € if you rent all the month. If you buy a car, insurance is really expensive. If you come from the United States you can drive a rent car, but if you want to buy one you will have to do the exams to get an Irish driving license. Insurance is particularly expensive, with prices that could be as insane as €4,000 if you don’t have a no claim bonus. If you are American they will not accept your American no claim bonus. Some of the insurances wants you to buy in one go, while others will allow you to split the payments in 30% in advance, and then every month. Knowing the tricks I was able to get my insurance for €1,250.


Cork airport is small, but comfortable. The bad point is that they don’t have many direct flights. Dublin has. We have direct flights to Barcelona, but seasonal, from end of March to end of October, with Aer Lingus.

Normally you’ll go to Dublin airport by or and fly direct to Barcelona, or you will fly from Cork to London to Barcelona, or from Cork to Amsterdam to Barcelona.

There is one ferry to Santander, Spain, and another to France.

Local food

Food in Ireland has very good quality. In Cork there are many farmers, and is not strange to see the photo of the local farmer and the address of the place, when you buy products in the supermarket.

Meat is very good, the milk, and the bread which last only few days.

The most famous is probably the Irish breakfast, very similar to the Scottish breakfast including sausages, red beans, pudding (in Scotland they call it haggish), eggs, rashers (bacon), a potato triangle

This is actual breakfast from the cantine at work

I just discovered today that is like a tradition doing on Tuesday pancake (what we call a crep in Barcelona).


Cork is the second biggest city in Ireland, with a population of 280K. However being the 2nd doesn’t make it impressive in terms of number of citizens. Ireland is a small country, with only 4M inhabitants, and that you can cross from the bottom to the top, by car, in around 4 hours (I counted the Northern Ireland here), but this is a reason why people live very well.

Ireland is full of green and nature, and if you are outside the city you can notice how pure the air is in here.

If you compare to the F.C.B. “Camp Nou” stadium in Barcelona, with 99,354 sittings, or to the 2 Million people demonstrations for independence in Barcelona, you see that is no that much.


Official languages in Ireland are English and Irish (Gaelic).

All the official messages and driving signs are bilingual.

Cork citizens have the well deserved fame of having the most difficult English in the world. And it’s true. It was not only me at the beginning, there are Americans that don’t understand the accent too!. Basically it has a characteristic music and they remove all the spaces between the words, modulating also the volume of the sound. If that was not enough, they have their own slang and there are many books with that slang, so don’t make me guess how many words in the slang they have!. I can tell you that they have phrases, that, depending on how they pronunce have antagonist meanings.

Here we say runner, for running shoes, rashers, for bacon strips, we say grant or it’s grant to say that is Ok, and heya, thankya, bye now… not to bad, to express we are fine, it was mank (this food was horrible), this was deadly or class (like terrific), sound (thanks. Can also say he is sound), story or what’s the crack to ask how is going, he has notions (he believes is better than the others because he bought a car, or a big tv) and if you hear tikety boo (all Ok), or oki doky karaoke don’t be surprised. :)

We also use jump the gun (come to a conclusion too quickly), fair enough, and in my work we say informally go bananas or go coocoo although I think I’ve heard this to the Americans too.

I love specially the expression thanks a million, that actually comes from the Irish (Gaelic) language. And if you’re asking yourself, few people talk it fluently. Most of people have notions as it is taught in the schools, but not many families speak Irish at home.


Religion is Catholic, and they practice and only in 2019 was voted in referendum to approve the abortion.

airbnb and hotels price

Airbnb is legal, and people uses it. Myself I was host in my flat for a while and was a great experience.

I had a lot of people from Dublin, that came to Cork for a concert or a wedding, and they just need the room to sleep, one day or two, basically.

Hotels price is like Barcelona between €100 and €150 euros per night. This price can be much higher if there is a congress. There are many seasonal activities where the city is full.

Something very typical to use is the B&B, Bed and Breakfast. B&B is a big house, normally managed by a family living there, that rent rooms, like if it was a hotel. Many Irish use it when going to a wedding or to visit the family and are very popular here. Typical prices are €100 or €50 euros per night. That’s typical in Scotland as well.

Finally the hostels, the cheapest price I have heard is a bed for €17 per night, but in a room shared with 7 more people.

Price of the rent

Price of the rent has been increasing like crazy in the last two years. A 2 bedroom flat, with 2 bathrooms, and furniture will cost at February around €1,500/month.

People live in houses, more than flats. Except for the city center, of course.

If you don’t mind to live in a house, far from the bus and the city center, probably you can get a house with 3 bedrooms and 1 bathroom per 1,300/month.

You need references. That’s very important.

The best website to find properties to rent, or rooms, is

The usual is to leave 1 deposit and pay the current month, if the Landlord or Landlady hired an agency, they are the ones that will pay the agency.

English and expats

Some of my colleagues are afraid to go to an English speaking country cause they feel ashamed, they think their accent is not very good.

Well, the English of Cork is difficult, but they know and will speak to you slowly if they see you have difficulties. Don’t be afraid to say “Say it again” “Sorry, can you repeat?” “Did you mean xxxx?”.

In my first job here most of my IT colleagues were expats: from France, from Italy, from India, from Romania, Kurdish, from Nigeria, from Spain… all of them have a different accent and we understand each other. And if you go to meetups (I recommend in order to know people) or conferences, you’ll see that many have a terrible accent worst than you. Fortunately English speaking people understand that English is not native language and value your efforts. If you ask them to correct you, you’ll learn and improve very fast. We’re very lucky to be appreciated for our intelligence and not for how we dress, or for our accent.

And many times locals will fins your accent very exotic and interesting. :)

In my second job there is not a single Engineer in Operations Irish. I’m Catalan, there is Italian, Indian, German, Russian, Romanian, English, Danish…

So Ireland is very welcoming, and is hungry for IT experts.

Salaries for IT

90% of IT companies in the world have presence in Ireland. That’s massive.

Here, in Cork, you have nice companies like Blizzard, Ibm, Quest, Dell, Logitech, Qualcomm, Vmware, McAffee, Trend micro, Facebook…

For people not in IT, there are several companies that provide Call Support in different languages, like Apple, VoxPro… so many non IT people work there.

Salary varies a lot depending in which role you work and if is a big company.

For the first multinational I worked here, a grad, which is basically somebody that finished the degree and has two years of experience, or that finished the degree and did one master, the salary was €30,000 gross per year plus 20% optional yearly bonus.

A Senior Software Engineer with 5 years of experience developing Software will get between €60,000 and €75,000 gross per year. Salaries in Dublin are around 15%, or more, higher but the rent it is too.

As Cloud Architect I had offers of 6 figures.

The minimum wage for an adult at Feb 2020, is €10.10 per hour, that’s around €1,656.20 net per month.


Internet is good and many places have fiber.

Myself I live in a quiet area, 15 minutes by car from the center, and I have a 360 Mbit/s fiber connection.

In some places they have 1 Gbit/s connections.

As people tend to live in houses instead of flats (the city center is really small) many places can only use DSL or poorly 4G connections, which is very annoyng during covid-19 lockdown and WFH as we have to disable video in chats with the colleagues.

Office material

The paper we use here is Din A4, like in Catalonia.

Buying Hardware

There are two Hardware stores in the City Center. The rest you will have to order using

If you look for an UPS (Uninterruptible Power Supply), you may see that most of them are not shipped to Ireland. This is due to restrictions flying batteries.

There are specialized sites in UK where you can buy and they will ship them to Ireland.


I consider Cork a very safe city. Starting a fight is a crime, and because their polite personality, violence of fights are not the usual. Exception to this can be found in the city center, late at night, with young (and not so young) people drunk.

People, men and women, walk fearless by the street at night.

Must say that the situation has gone a bit worst since the last two years, cause heroine has arrived to the city, and that causes some addicts to act in desperation. There are really few cases. Any tragedy or violent crime appears in the newspapers and is a new for a week, pointing, that fortunately this is not frequent.

People leave their belongings in the coffee and in the pub while they go to the restroom or to smoke. This is something you cannot do in Barcelona.

However I have known of some foreigners stealing jackets in pubs like Craig Lane. It is a shame that they do this in a so nice country like this.

It is super safe specially if we compare to Dublin, where I’ve seen yonkies running and taking the phone from people talking, in the street, or going in bicycle and stealing by pulling the cameras on the neck of Japanese tourist (that I’ve been told, I didn’t see). I don’t like to go to Dublin for that reason.


There is one kind of police only, the Gardai.

They don’t carry guns or batons, as Irish consider that this scales the violence. That if police has guns, bad guys will have machine guns, etc… So basically they try to convince the offenders to stop their attitude and surrender. They have a unit of weaponized gardai for emergencies.

My interactions with Gardai have been very positive. They have been very nice, polite, attentive. Coming from Barcelona where Spanish police hits the voters of a referendum, or hist the Catalans citizens, just cause they are Catalans finding normal policeman at the service of the citizens is something I really value.

An American friend of mine that was police, adds that wearing a knife is illegal.


The pub close around 1:30 AM, some at 00:30. When they do the “last call” means that is the last 5 minutes you can order drinks. After that they will start cleaning and you can stay while they do, normally for half an hour or an hour more, finishing your drinks. So yes, when it’s last call some people order 3 beers.

Almost all the pubs in the city center play live music almost every night. Few specialize in traditional Irish dance, most are modern rock singers or bands.

There is a disco that closes late, is called “Vodoo rooms”, and has 3 different kind of musics / ambiances with a terrace on top where is it possible to smoke. It is very well dimensioned in terms of security, and personnel is all the time attentive to detect liquid on the floor or broken glasses, and the clean everything very quickly and effectively.

Security guards in the pub have a band with their photo, name, and license number. Only people that passed the certification can be security guard. Many of them are people in their 55, so it’s less likely that they’re going to cause trouble to customers. In fact I found them very attentive, telling me hello and bye every time.

Dangers/Terror histories/Bad experiences

As said I don’t have the perception of danger in Cork, however, there is a warning signal that things can be wrong with youngsters.

This is something than an American expolice and I discussed, and he had the same impression. I have discussed with other adults and see the point like me.

The young guys, between 15 and 17 y.o. go in gangs, in groups 10, 15 or 20, and at that point they can be rude, disrespectful, have fun at the expense of others or damage a property for fun. This is the biggest danger we see.

Coming from Barcelona I laugh at the attempts of some young guys in group to pretend to be though and intimidating, so no big deal, but I had a bad experience twice, when I was walking in the street and a group throw me an egg, from behind from a running car.

I was walking using my headphones when suddenly I saw the egg passing by my side and exploding on the floor, half meter in front of my feet, and the car running away. They missed it. But as I continued walking I saw more eggshells and egg contents on the floor, so they were targeting random people for fun. That was when I had been for a year in Cork, and I decided that this will not ruin my positive experience.

I talked to my boss and he told me that this is something relative popular that some youngsters do, and that he used to find it funny when he was a young boy (he never did) until he knew about the case of a woman, that just turn back at the same time that the egg was coming from behind, at high speed as coming from a car, and impacted in her eye, making her loss her cornea, so the eyesight of one eye.

The second time I was walking on the same street, 2 Km distance from the when the first time, I was in front of the hospital, walking to the gym. I was walking 3 hours every day, and spending 45 minutes more on the bicycle in the gym, every day. As I walked my way to the gym, passing in front of the hospital, with my headphones and my hood, as it was cold or slightly raining, I noticed a heavy impact in my right arm and I got scared and my reaction was to get defensive to fight back. In slow motion I saw the egg bouncing from my arm to the floor. It didn’t explode on contact with my jacked and arm, bounced, and exploded in the floor without getting to me. As my reaction was to get scared by the impact in my arm, and my primary reaction was to fight back, they were lucky that I was talking by phone with a relative, and I explained what happened, which prevent me from my impulse to run after the car. They were lucky, cause 200 meters ahead they had to stop cause there was a semaphore and cars stopped by. They could not have escaped if I chased them and hit the windows. Fortunately nothing of this happened.

There is a community of poor people that live in tents. That’s very sad. Here is really cold, under 0 centigrade degrees some times (today 29th Feb we are at 2 cent. degrees. There are young people also in there, I read about one case in the newspapers. They could have died out there. Social services are insufficient according to the locals and they organize charity to help them live in a better place, provide better clothes, etc… Those people living in tents are exposed to drug addicts that rob the place trying to find money or something to sell.

This is the dark side and many of my expat colleagues do not know this. I live in Cork since 3 years ago, I’m well integrated, I read the newspapers, have local friends, ask the taxi drivers… so I know.


I would say that Cork, even being Catholic, is open to LGTB+. For St. Patricks cellebration some drag queen are in the carousel.

There is at least one bar/disco declared LGTB+ Friendly. Is The Chambers.

They do very nice concerts on Saturdays, and on Fridays they do Karaoke.


You must be advised, that unless specified different, restaurant will close the kitchen at 9:00PM (21:00).

Cofe places close around 6PM, at 8PM in the city center with few exceptions. (In Barcelona I used to go to a coffee that closes at midnight or later)

Most of the pubs serve food until 21:00 too.

Current version is v.0.7.5 updated on 2020-06-28 13:15 IST (Irish Standard Time).

Find the source code in:

Clone it with:

git clone is an Open Source tool for Linux System Administration that I’ve written in Python3. It uses only the System (/proc), and not third party libraries, in order to get all the information required.
I use only this modules, so it’s ideal to run in all the farm of Servers and Dockers:

  • os
  • sys
  • time
  • shutil (for getting the Terminal width and height)

The purpose of this tool is to help to troubleshot and to identify problems with a single view to a single tool that has all the typical indicators.

It provides in a single view information that is typically provided by many programs:

  • top, htop for the CPU usage, process list, memory usage
  • meminfo
  • cpuinfo
  • hostname
  • uptime
  • df to see the free space in / and the free inodes
  • iftop to see real-time bandwidth usage
  • ip addr list to see the main Ip for the interfaces
  • netstat or lsof to see the list of listening TCP Ports
  • uname -a to see the Kernel version

Other cool things it does is:

  • Identifying if you’re inside an Amazon VM, Virtual Box, Docker or lxc
  • Uses colors, and marks in yellow the warnings and in red the errors, problems like few disk space reaming or high CPU usage according to the available cores and CPUs.
  • Redraws the screen and adjust to the size of the Terminal, bigger terminal displays more information
  • It doesn’t use external libraries, and does not escape to shell. It reads everything from /proc /sys or /etc files.
  • Identifies the Linux distribution
  • Shows the most repeated binaries, so you can identify DDoS attacks (like having 5,000 apache instances where you have normally 500 or many instances of Python)
  • Indicates if an interface has the cable connected or disconnected
  • Shows the Speed of the Network Connection (useful for Mellanox cards than can operate and 200Gbit/sec, 100, 50, 40, 25, 10…)
  • It displays the local time and the Linux Epoch Time, which is universal (very useful for logs and to detect when there was an issue, for example if your system restarted, your SSH Session would keep latest Epoch captured)
  • No root required
  • Displays recent errors like NFS Timed outs or Memory Read Errors.


  • It only works for Linux, not for Mac or for Windows. Although the idea is to help with Server’s Linux Administration and Troubleshot and Mac and Windows do not have /proc
  • The list of process of the System is read every 30 seconds, to avoid adding much overhead on the System, other info every second

I decided to code name the version 0.7 as “Catalan Republic” to support the dreams and hopes and democratic requests of the Catalans people to become and independent republic.

I created this tool as Open Source and if you want to help I need people to test under different versions of:

  • Atypical Linux distributions

If you are a Cloud Provider and want me to implement the detection of your VMs, so the tool knows that is a instance of the Amazon, Google, Azure, Cloudsigma, Digital Ocean… contact me through my LinkedIn.

Monitoring an Amazon Instance, take a look at the amount of traffic sent and received

Some of the features I’m working on are parsing the logs checking for errors, kernel panics, processed killed due to lack of memory, iscsi disconnects, nfs errors, checking the logs of mysql and Oracle databases to locate errors
