Dell XPS 13 7390 Wifi Problems

Hello everyone,

If you are a develepor in today’s day and age, you might have requested to get a Dell XPS laptop. Of course you asked for the Ubuntu developer version. Hopefully you got it.

If you didn’t get it, and got the Windows version instead, you installed Ubuntu, and probably no longer have Wifi. That is what happened to me. Lets solve it.

To start, when the laptop is boothing, go into the BIOS and make sure you get the model right. After that, with the model number, go into Dell’s website and get the specs - precisely the Wireless card model.

In my case, it said the Wireless card was a Killer AX1650W but it said on every Ubuntu menu Intel Corporation. This is because the Killer card was a partnership with Intel I assume. So don’t lose your mind thinking that you got a different card. Just follow all the stackoverflow tutorials.

The best is to check the Killer website though: here.

Follow the steps, reboot, and you are done. Wifi is back!

Thanks for reading,


Reflection on work

I am writing this post to reflect on my career so far, and how I got to where I am. The situations I have been through have shaped me, my decision process, and how I behave in a team/company. I hope that this text helps whoever reads it - how a guy that studied physics got into the startup world, and made something out of it.

My highlights from The Phoenix Project

I am 6 years late to the party. The first edition of The Phoenix Project came out in 2013, and I only got it now. I don’t remember the last time I picked up a book, and could absolutely not put it down until I was done with it. If you haven’t yet read The Phoenix Project, I highly recommend you get yourself a copy and start. In my opinion this is a book that every struggling developeri, IT department, or business leader, should pick up. I am very aware that I am not the first to say any of these things, but bear with me. I write my findings to make sure I don’t forget them.

The Phoenix Project explores the life of Bill Palmer after a sudden promotion from Director of Midrange Technology Operations to VP of IT Operations. Coaxed by his CEO into accepting the position, Bill now has to save the company’s failing project, whilst firefighting IT issues to keep the company moving. Bill faces many issues during his first few days, but reacts accordingly. He sets up a team, tries to understand how he can better manage the reocurring issues, and tries to reorganise work.

Things get worse before they get better, but with the help of Erik he finds his footing and comes out the other side victorious. Erik has some lessons for Bill throughout the whole book, which I will try to list, and explore. Keep on reading.

Use psycopg2 to query into a DataFrame

I love working with Python + Pandas, but sometimes working with lots of data or even loading that data into memory can be a problem.

It can be better to have a database to perform DB operations, like merges and filters, and then do the final operations in Pandas, when the data is more manageable. For that I use Postgres + Python, with psycopg2 before loading the data into Pandas. Lets get to work!
