Ubuntu

I use a Pocketbook Touch HD first gen. to read ebooks and I bought it in 2017 (oh dear!). It’s a really good device, despite being terribly slow according to current standards and battery have probably only 20% capacity comparing to the day I bought it. Anyway, it outperformed any of my smartphones on it’s longevity. I don’t use it that often anymore but it happen to me to read some stuff that I find on the Internet. ...

New system, old problems. Getting Oracle Instant Client to work was a trouble 10 years ago and it’s not different today 🤣 There are two ways to install it on Ubuntu/Debian. First is “recommended”, but boring. Second is “crazy”, but have some benefits. As I’m doing it mostly in Docker images, that’s how I will present it. First, check for up to date versions  external link and links on Oracle’s official site. ...

Around 3 years ago I’ve checked the age of various base images available on Docker Hub. Curiosity recently got the better of me, prompting another investigation into the current state of affairs. Since then, there have been significant changes: CentOS 8 has reached its end of life  external link , prompting a shift to CentOS 8 Stream  external link , which is also nearing its demise 🤣 OpenJDK images have been deprecated  external link and no longer receiving updates. They recommend to switch to alternatives such as: Amazon’s Corretto or Eclipse Temurin (formely AdoptOpenJDK). Let’s delve into the findings: ...

TL;DR If you’re not interested in the “story of my life”, go directly to “Tuning PipeWire ” section. I’m not an audiophile, but I spent whole days in the headphones and I like when sound sounds good. I like slight bass boost, which adds this kick to the melody, but won’t overwhelm me after an hour of listening. I like when high tones are clear, but I get annoyed if they’re too strong. And finally, I hate all cracks, hisses or electric circuit noises. ...

Since upgrade to Ubuntu 22.04 keep seeing those warnings: W: http://ppa.launchpad.net/yubico/stable/ubuntu/dists/jammy/InRelease: Key is stored in legacy trusted.gpg keyring (/etc/apt/trusted.gpg), see the DEPRECATION section in apt-key(8) for details.

I already cleared all of them in my Docker images, but somehow I didn’t fix my station. ...

What I want to do? I use my pool to securely store backups, archive my old documents and keep huge family’s photo library. I have new disks. They were tortured with badblocks , so they’re ready to create ZFS pool. I’ve read few documents about different approaches 1 2 3. I wanted to be sure if anything changed during past years. One of articles recommends mirroring over RAIDZ. Resilvering is faster, at the same time putting IO less stress on whole pool. But pool as small as mine, relies on single drive which might die in between and data won’t be recoverable. Eventually, I decided to go for RAIDZ1 for now and in the future I rather move to RAIDZ2. For that, I have to buy one more disk - Black Friday is close, we will see. ...

Lately I was searching for mobile notebook that I could use for remote work. I checked f ThinkPad series but they were huge bricks that have nothing in common with ‘mobile’ word. Then I saw ASUS Zenbook that I didn’t take into account before and it was exactly what I was searching for. Configuration of Skylake based notebook right now is not straightforward - there are still glitches and small bugs that are waiting to be fixed. I want to sum up what I’ve done after installation. I started with fresh Ubuntu 16.04 to get Debian based distro with possibly latest kernel and patches. ...

I’ve played with Docker a little in it early days but didn’t stick for longer with it. It’s stable now so I wanted to check how it’s running now. I really can’t accept this method of installation: curl -fsSL https://get.docker.com/ | sh I think that world is going to it’s end when I see such scritps… I prefer to do this manually, knowing exactly what I have to do. Install prerequisites: ...

From few days I have access to UPC’s www.horizon.tv  external link platform - until now it was useless on Linux. But there is Pipelight that will use Wine to emulate Silverlight on Linux and it’s working pretty well - you’re just few commands away from achieving that: # stop browser killall firefox # remove old version if you have it sudo apt-get remove pipelight Now configure repos and install packages: ...

Now when you have CollectD and InfluxDB installed you may configure Grafana 😃 First configure repo with current Grafana version (select your distro): curl https://packagecloud.io/gpg.key | sudo apt-key add - deb https://packagecloud.io/grafana/testing/debian/ wheezy main Now install package (on wheezy I needed to install apt-transport-https to allow installation of packages from repo via HTTPS): apt-get update apt-get install -y apt-transport-https apt-get install -y grafana By default Grafana will use sqlite database to keep information about users, etc: ...
