I guess you have noticed the one or other of my recent articles over the past few weeks about the experience I have gained with my new ‘refurbished’ workstation. While I previously thought that single core performance of x86 processors in high end workstations and particularly in data centers must be so much more powerful than the CPU in my notebook, my recent experience tells me otherwise.

High processing power comes with high power consumption. I guess that can’t be helped much but one way to reduce the power bill for that number-crunching ‘headless’ workstation under the desk without screen and keyboard is to suspend it at night and at times during the day when it is not needed. As long as it can be done from my notebook and as long as it’s as easy as pressing the COMMAND+L key that locks the screen of my notebook and puts the display on the desk into power save mode, that should not be too hard to do in practice.

In the previous post I ran FFmpeg and Handbrake on the 6 core CPU of my workstation and got a good but still modest 2.5x speedup of the video encoding task compared to running the same operation on notebook. I would have expected at least a 5x speedup and I’m still puzzled why I didn’t get there. But I have moved on for the moment and have taken a closer look if I could make FFMpeg and Handbrake use the H.264 hardware encoder on the Nvidia Quadra M2000 GPU instead of running this tasks on the CPUs.

This is part 2 in my article series on using a Xeon based 6 core 12 thread workstation at home to offload CPU intensive tasks from my notebook to a more powerful and fast server. At the end of the introduction I had an example of how my picture fix, rotate compression tool runs 5 times faster on that machine than on my notebook, which significantly reduces my wait time in many everyday scenarios. So how do other programs fare when running them on the workstation?

It was 2004 when I bought my last workstation for use at home, a Siemens Fujitsu Pentium 4 tower PC. After that I shifted to notebooks as they became cheap and powerful enough to do almost everything with them I wanted to do. Even my 5 year old refurbished Thinkpad X250 is an excellent machine for pretty much all I want to do, and it handles my 21:9 monitor with a resolution of 3440×1440 pixels without breaking a sweat. Even my 7 year old X230 can easily do that, while running two virtual machines, one with Windows and one with Ubuntu alongside. But it has its limits especially for computing intensive things as I recently discovered. Not finding the performance I was looking for in the cloud for a reasonable amount of money I was wondering if a workstation at home would be something that could push the limits?
There has been a time when DVDs where the main medium for backups and for acquiring audiovisual content. These days might long be over but I still have quite a collection that I would like to keep. Unfortunately their lifetime is not endless and most of my devices no longer have a DVD drive. And those that I still have are not very reliable anymore and have started refusing to read more and more of those DVDs lately. So it was time to think about how to preserve the content and make it more easily usable with current devices.
If I could get it my way, I’d probably put LineageOS or another proprietary Google and hardware manufacturer free Android version on my tablet. While this is possible with some tablets, I would however loose the pen and handwriting input which is an absolute must to use the tablet not only for media consumption but also for work. So I made the best out of the situation and here’s a short overview of my setup:
For many many years I’ve used ping in a shell window which I placed in the lower right corner of the screen to monitor my Internet connectivity. So when something network related stopped working I would immediately look there to see if the Internet was still reachable. Crude, but quite effective. But being far from perfect I’ve now spent a bit of time to write a nice GUI program for the purpose that also expands the functionality a bit.
I’ve been using a tablet on and off for many years now. However, it’s been mostly off as I was mainly using this device type for media consumption, i.e. web browsing, videos, reading ebooks, etc. rather than creating content. Recently, however, I’ve taken another look at tablets with a pen and how they can be used in combination with handwriting notes and for annotating PDFs. While entry level tablets can be had for less than 200 euros these days, it looks like those that can handle pens well for handwriting start at around 300 euros. To see what kind of difference price makes in 2020 for the use cases I had in mind, I bought a €650 tablet and another one for €320. Both came with the pen included. I don’t want to mention makes and models here because I don’t think that’s relevant for the comparison. And indeed, the difference is quite noticeable, not only in the details.

As a quick follow up to my previous post here’s a quick thought about how despite working on that terabyte per month data use, it is still ridiculously low when looked at from an overall line capacity point of view.
