This is my fifth noodling and I did cut a few things. I will be playing with the length but this is about 13 minutes of my nonsense to chip tunes. The 5th noodling installment can be found here Commodore 64 IRC Success I was able to get my Commodore 64 under its own power … Continue reading Noodlings 5 | Building and Converting →

Είδαμε πως μπορούμε να εγκαταστήσουμε το viber μέσω του snap. Αυτό δεν θεωρείται επίσημος τρόπος για μια διανομή με βάση το GNOME. Πιο επίσημος θεωρείται ο τρόπος της εγκατάστασης του πακέτου flatpak. Πως μπορεί να γίνει αυτό;

1. Εγκατάσταση του flatpak.


2. Εισαγωγή του αποθετηρίου flatpak.


3. Επανεκκίνηση του συστήματος

Για περισσότερες διανομές, μπορείτε να βρείτε πληροφορίες εδώ.

4. Η εγκατάσταση μπορεί να γίνει απευθείας από την διεύθυνση:

https://flathub.org/apps/details/com.viber.Viber

ή αν κάνετε μια αναζήτηση στο software center της διανομής σας.

Εάν θέλετε να ψάξετε περισσότερα προγράμματα, μπορείτε να βρείτε μια λίστα εδώ:

Στην διανομή openSUSE δυστυχώς το πακέτο rpm που κατεβάζουμε από την ιστοσελίδα του viber, δεν δουλεύει. Οπότε αυτός θεωρείται ίσως ο μοναδικός τρόπος για να έχετε viber στον υπολογιστή σας.

This below is a screenshot of my LibreOffice build using the Skia library.
Now, admittedly, this looks way better than it should, as it is actually still far from finished. It is so far X11-only, using the venerable not-that-performant XPutImage(). No Windows, no Vulkan. Yet. Also, while it passes all VCL unit tests, that rather says something about the poor state of coverage of those tests, as they fail to hit any of those abort() calls I still have in a number of places. Well, maybe I should rather post the screenshot from yesterday:

The Commodore 64 was my first computer and as such, now holds a special place in my heart and probably forever more, or at least until I lose my mind completely. In all the years I had a C64, I never visited a BBS as I didn’t get that bit of tech until I got … Continue reading Commodore 64 on the Internet | IRC →

Disponibilizo um artigo no Viva O Linux, para exemplificar como instalar e configurar o Ubuntu Touch em equipamentos compatíveis com o projeto. Ao contrário do que muitos imaginam, o sistema operacional está ativo e muito funcional, ao ponto de utilizá-lo no dia a dia sem sentir saudades do Android, iPhone ou outros sistemas operacionais. E como cereja do bolo, contamos com a funcionalidade de convergência, e transformá-lo em um desktop. Leia o artigo na íntegra AQUI!

Last week the openSUSE Security Team spent some time to check and review the PAM module from the pam-python project. Main reason for that – to make sure that the source code of the project is secure enough and bug free of course. Badly implemented PAM modules may cause user authentication to always succeed or otherwise badly influence security.
The audit process was done by Malte Kraus. He found the local root exploit in version 1.0.6, which was the last stable one since August 2016. Reaction from the upstream comes immediately: Russell Stuart, who is author of pam-python, released the new official version – 1.0.7.
PAM module from version 1.0.7 is whitelisted by openSUSE Security Team. I rebuild the new packages of pam-python and made it available for all openSUSE users.

Anytime someone wants to give me a piece of hardware, it’s hard for me to say, “no.” I received this Acer AspireOne D255 as payment for installing openSUSE Leap on an HP Laptop. This little netbook was a bit slower than my other Acer AspireOne and with only 1 GiB of RAM and a dead … Continue reading Acer AspireOne D255 with openSUSE Tumbleweed Xfce →

The universe is full of captivating, compelling and exquisite things. The internet, the most complete representation of humanity, is no different in that regard. Both are vast, seemingly endless and full of places you should know about. Let me share content that has moved me, in some way, in the last month. This time it's mostly think-pieces, an event and a couple of tools. Enjoy!

The Evolution of Trust by Nicky Case

A lovely explanation of trust in game theory. It's an interactive "game" in which you can try out how the rules of the game and the strategy influence the distribution of archetypes of player. I don't think realy humans act anywhere near as rational and consistent as players in game theory, yet, some effects are incredible to whitness first hand.

Thinking, Shallow And Deep by Thomas Oppong

My zodiac sign is sloth and easygoing is two cornerstones of my doctrine. So I'm not very fond of self-optimization, especially not in the startup context. But somehow this piece by Thomas hit it with me. In it he pulls together a couple of thoughts about the act of deep thinking. How that helps you to avoid confirmation bias, how that is a good thing in the information age of life long learning. But also how current society (unintentionally?) distracts you from it. A nice thread thought, asking powerful questions.

Why Don’t We Just Call Agile What It Is: Feminist by Hanna Thomas

There, she said it! Collaborative, supportive, non-hierarchical relationships that empower people and embrace change are at the core of many progressive feminist theories. And obviously they have been a big influence on agile. An Agile mindset is a progressive feminist mindset. I couldn't agree more.

Incredible Doom (Season Finale) by Matthew Bogart

Ah the '90s! Everything was possible and doomed, at the same time. If you, like me, grew up during this decade then this is for you. A comic series about '90s kids making bad decisions over the early internet. If you grew up some other time, check it out to understand what this internet thing really meant in the beginning. Might explain why so many of us still won't let go of the quirky edges of it, despite all the surveilance capitalist bullshit on the frontpage now. Especially the printed issues make me drool.

PROVIDED AS IS by the people at Formidable

Another event targeted at free software/open source project maintainers with the expressed intent to explore the set of skills beyond “just coding”. At some point in time some of us are going to have to pull all of this shared knowledge about tactics out of conversations into a book or something.

indexter by Chris Cummer

Ruby gem for checking Rails database tables for missing indexes on foreign keys. Happy hunting, hope you find at least one that has a nice performance impact on your app.

Redash & Metabase

I'm on an ongoing quest for the perfect Free Software observability sidecar. I need oberservability. I dread every day I wake up to Mysql2::Error::ConnectionError for some requests in my exception tracker without the ability to ask it about the status of the network or SQL cluster during that time. DIGAME! Both tools focus on sharing questions people come up with, as collaboration addict I very much like that. Both are Free Software with people making money from it, like that even more!

That's it, hope you enjoy this stuff as much as I did.
