My BIOS was 4 years out of date. I thought it was time to update it. I went to the Dell Support page and noticed that they only had *.exe files available. I sighed and was initially frustrated because my initial supposition was that I was going to have to have a working copy of Windows to do the update.
Installed a game called Pokemon Insurgence on Lutris and there was no way to play the game with a gamepad. Rather than try to fight things, set out for an application that would map the keyboard controls to the WiiU Pro Controller that has become my gamepad of choice.
After receiving this message following a BIOS upgrade, I was forced to purchase a lower powered CPU for my AMD Workstation.
The NDI plugin offers a fairly easy way to send OBS video signal (presumably other applications can take advantage of this too) to another OBS instance on another machine. This can come in handy for numerous reasons such as splitting up workloads between machines by capturing output from one machine, such as gaming computer, to stream with a dedicated unit that interfaces with YouTube.
The pioneers in the field talk about 5th generation computers capable of Artificial Intelligence and heuristic learning; giving computers context. In 1984, computers were already being used to make knowledge based decisions.
Take some time to have fun. Good, clean wholesome fun. Go for a walk, enjoy the weather on any day that it is possible. Take some time to cherish each moment, whether it is good or bad, find the positive in the situation and make it a point to say “thank you” as often as possible.
I have historically made my hardware decisions based on price, generally I get what I can get for as low or as reasonable as possible. Basically, I go for free or near-free and fabri-cobble something together. After seeing some other computer setups, I have really thought that I want to be able to function more effectively and efficiently than I had been. One of the areas that I have been less than happy has been my monitor layout. I have been pushing 3 displays with my Dell Latitude E6440 and for the most part, it has been meeting my needs but there were some work flows that have not been working out so well.
I can’t say that I ever spent my childhood wishing I had the ultimate terminal desktop but the more I have played on Linux, the more I have spent time in the terminal and I really can’t explain why I find it so charming. Perhaps it is the low memory usage of the applications? The clever modern implementation of certain terminal applications? I can’t really say, but there is something incredibly charming about the terminal.
This is another gift to future me from present me. I made the mistake of not properly writing this down before so I had to search for the answer. The problem is, sometimes, it seems as though Plasma is not shutting off my external screens consistently. I can’t say why but I have a suspicion that it is due to a specific communication application as I can almost guarantee that it is preventing my screens from turning off. I don’t have definitive proof of this so I am not going to put it in writing.
I’d like to say something interesting about the number 17, it’s a prime number, the last year you are a minor in the United States, perhaps other places… Team 17 was a great video game house in the 90s that made the game Worms, that was cool. Played that quite a lot some years back…
Used Fusion 360 on Linux to help me design a major renovation project. I need a new space for my dusty projects, a place to make wood and metal chips and other non-electronics friendly tasks like welding.
Ubuntu Cinnamon Remix is struggling with their process to become an official distribution due to 3rd party packages

Community feedback, concerning getting into Network Administrator, get your hands on, buy some cheap used equipment, get the Debian network administrator handbook. Get real equipment seems like the best way to learn.
For me, Ocular for reading. For managing ebooks, I use Calibre. Folio was talked about but it looks to Gnome.
Organizers of the openSUSE + LibreOffice Virtual Conference are extending the Call for Papers to August 4. Participants can submit talks for the live conference past the original deadline of July 21 for the next two weeks. The conference is scheduled to take place online from Oct. 15. – 17.
The length of the talks that can be submitted are either a 15-minute short talk, a 30-minute normal talk and/or a 60-minute work group session. Organizers believe shortening the talks will keep attendees engaged for the duration of the online conference.
The conference will have technical talks about LibreOffice, openSUSE, open source, cloud, containers and more. Extra time for Questions and Answers after each talk is possible and the talks will be recorded. The conference will schedule frequent breaks for networking and socializing.
The conference will be using a live conferencing platform and will allow presenters with limited bandwidth to play a talk they recorded should they wish not to present a live talk. The presenter will have the possibility to control the video as well as pause, rewind and fast-forward it.
Attendees can customize their own schedule by adding sessions they would like to participate in once the platform is ready. More information about the platform will be available in future news articles.
Organizers have online, live conference sponsorship packages available. Interested parties should contact ddemaio (at) opensuse.org for more information.
The openSUSE release team is would like feedback from users, developers and stakeholders about the release of the of community-developed openSUSE Leap 15.2 through a survey. The survey is available at https://survey.opensuse.org. openSUSE Leap 15.2 was released on July 2. The survey centers on these two questions: what went well and what didn’t go well?
Add mozilla-libavcodec58_91.patch to link against updated soversion of libavcodec (58.91) with ffmpeg >= 4.3. libzypp (17.24.0 -> 17.24.1) Fix bsc#1174011 auth=basic ignored in some cases (bsc#1174011) Proactively send credentials if the URL specifes ‘?auth=basic’ and a username.

Computer History Retrospective
Computer Chronicles – Microchip Technology
Value of computers today is enormous and this put that into some of its perspective.
It is never good to live in fear. The world is indeed a dangerous place, filled with so many things that reWe are often focused on the negative in the world. The things that are bad or could be improved and often become far too resentful as a consequence. If we spend more time focusing on the miracles that bring us the technology and comforts we get to enjoy day in and day out. I think the world would be a better place
There are certain numbers, due to my nerdiness, that have importance to me. 16 is one of them. Some people get excited about reaching 10 or 20 or 100, I get excited about base 2 numbers. 8, 16, 32, 64 will be huge! I’ll have to plan something special for number 64.
I decided to have a properly socially distanced virtual installation party with openSUSE Leap 15.2. It was a nice small group of people. I enjoyed this kind of question answer forum. I had a few people on in the BDLL Discord server for live chat and people on YouTube sending messages
Updating openSUSE Documentation on the Wiki
This was sort of an impromptu activity. I wanted to update the documentation that I maintain for openSUSE and decided to do it while on a live stream and make it a chat with virtual friends.
Now on LBRY
Mostly for the reason of having a backup and other options for people to access the content I create
Concern about information being lost in the block-chain. Several videos I have tried to watch stopped playing with errors.
This is a great retrospective on how far we have come with mass storage devices. Last part of a computer that was still mechanical
At this time there was rapid development happening on magnetic storage mediums. In a short period of time, the technology packed only a few thousand bits per square inch and quickly moved to 8 million bits per square inch and beyond.
Guest, Alan Shugart from Seagate technology shared that the introduction to the 8″ floppy proved the tech and the 5¼” floppy helped in the explosion of the home computer. Intel’s bubble memory device, a solid state device would not ever replace the floppy. Shugart said nothing will replace the floppy and that he didn’t see the 3.5″ replacing the 5¼” floppy because the world’s programs are all written on 5¼” floppies and he can’t see it ever being trans-coded onto another medium.
It is never good to live in fear. The world is indeed a dangerous place, filled with so many things that remind us of our mortality. regardless, you just cannot live in fear. Live every day with hope and optimism. Regardless of the crazy and awful things happening around us, we are still living the best time of human history.
I have become quite the fan of Gparted over the years of my Linux life and I started wondering if there were other partition management options out there. Specifically one that is Qt based instead. This is not a light on GTK based applications, I just find that they don’t tend to look as nice and clean as Qt apps. In this off-hand search, I stumbled upon PartitionManger which is in official openSUSE Tumbleweed and Leap Repositories.
I have reached the end of the road with this machine. We have been together for about three years and before sending it off to the ether, I wanted to try out openSUSE Tumbleweed on it. It was something of a question I have been asking myself since I was first assigned the piece of hardware. Windows 7 worked fine on it but how would it spin with the Plasma desktop.
In 2019, I bought into DeWalt 20v MAX cordless tool platform as part of my mission to reduce complexity in and improve efficiency in as many aspects of my life as possible. This is a long term mission of mine with many facets but basic tools was at the foundation of this plan. DeWalt has a great line of tools to choose from, but they are aimed at the commercial, industrial or professional builder. I would consider myself an intermediate or advanced DIY-er with the occasional moonlighting as either a handyman or builder, so I wanted some of those higher end tools to be available.
Organizers of the openSUSE + LibreOffice Conference have been slightly adjusted the conference dates from the original dates of Oct. 13 – 16 to the new dates of Oct. 15. – 17.
The new dates are a Thursday through a Saturday. Participants can submit talks for the live conference until July 21 when the Call for Papers is expected to close.
The length of the talks for the conference have also been changed. There will be a 15-minute short talk, a 30-minute normal talk and a 60-minute work group sessions to select. Organizers felt that shortening the talks were necessary to keep attendees engaged during the online conference. The change will also help with the scheduling of breaks, social video sessions and extra segments for Questions and Answers after each talk.

Computer History Retrospective
Computer Chronicles – Computers in Education (1983)
Fear of computers replacing teachers and dehumanizing education – I think in many ways this has happened but in a way, with the changes in multimedia, as opposed to the beeps and boops of computers in 1983, we have humanized computers a bit. With individuals creating tutorials and education personalities you can follow online have made more educators out of us as opposed to less – Terminal becomes a kind of personal tutor – Time at the terminal is more like a game – Computer instruction was more like rote training – Kids trained in logic – Logo whimsical way to tell a computer what to do taught
If you are going to spread anything, make it love, joy and peace. You can’t ever go wrong with that
In the 5th episode of the 1st season of Computer Chronicles in the year 1983 was an episode about Robotics. Lots of interesting speculation about the commercial viability of robotic devices.
Even at this time, robotics in manufacturing, or machines in general were starting to do many of the more dangerous tasks that could easily be replaced by some sort of structured process where robots could excel.
The fear of robots taking away jobs as seen in the early 20th century but the speculation that robots would completely eliminate all jobs doesn’t seem to have come into fruition. I know that today we speculate that automation will replace us in every way. It has in some capacities but I do believe it opens up the world for more skilled occupations. Robots and computers are certainly very disruptive to society, but they also give us new things as well.
Here is the video in it’s video tape recorded glory from 1983.
We all have immutable characteristics, things about us we cannot control about us. That will never make you less of a person
The killer feature of the Plasma Desktop has been the KDE Personal Information Manager, Kontact. I have been using it since 2004 time frame and although we have had a tenuous relationship over the years, specifically the switch to the Akonadi and the pain that came with it in the early years. I actively use Kontact on multiple machines for the feature richness of it and haven’t found anything in existence that I like better. I also exclusively use Kontact on openSUSE Tumbleweed with the Plasma Desktop Environment.
I have decided to publish my reference concerning the maintenance it requires. I could be an edge case since I have five mail accounts and multiple calendar accounts as well. Historically, I have had issues where losing network connection, regaining it, suspending and resuming my machine over a period of time would cause the thing to have fits. So, here are my fixes, whenever the need arises.
You know those stories of people that have these crazy habit ts that don’t make sense, things they do that don’t really help or solve a problem like making sure the spoons are organized in just the right fashion? Yeah, well that could be what this whole post is and my obsessive-compulsive tenancies are in full expression. So, take all that into account should you choose to use any of these references.
I recently purchased a new Logitech wireless keyboard for my kitchen computer because the Bluetooth keyboard I had previously used was driving me nuts. Mostly for the keyboard layout and sometimes because it didn’t want to connect. That was due possibly due to hardware failure or bad design. It also doesn’t have media keys, like volume control, so I thought it best just to replace it.
I have previously used ltunify with success but I only used it because “L” comes before “S” so that was my first stop. Since I received feedback that I should try Solaar I did so this time. Since there isn’t an official Linux based application available from Logitech, the fine open source community has stepped in to make managing your devices simple and straight forward.
Having Solaar in the system try is quite handy. Though, the reality is, I don’t need it all the time in fact, it isn’t actively running very often but having it to manage your devices is very handy. It’s nice to know that you can manage multiple Unifying receivers with this application. This is easy to use and has a great, well laid out and straight forward interface. I am glad I was recommended to try this application out. It has now been placed high on my list of tools to keep handy.
There comes a time in the lifespan of a computer where you decide that the performance becomes a little lacking. That was my case with this computer and the state of the drive was becoming a little dubious as it felt like it was getting slower and having periodic file system errors. Rather than just reinstall openSUSE on the same drive, I decided, I wanted to make an inexpensive upgrade so I purchased a Solid State Drive (SSD) for it.
Since I have taken this unit apart before, I already knew what I was doing with it. The back of computer comes off but does take some time to get all the snaps to release. I would really prefer that this was held together with screws instead of snaps. That is the only real design choice I don’t a care for with this machine. Upon releasing the back cover from the chassis, it exposes the 2.5″ drive which sits in the lower left corner of the machine. The drive is held in a caddy that snaps in to the chassis, no tools required to remove or insert the drive. I think this is actually quite the clever design.
The hardest part about the whole job was hanging the computer on the VESA mount. In fact, as much as I like utilizing VESA mounts, they are often a pain in the fanny to do without an extra set of hands.
The average read rate of this drive is 443.9 MB/s with 100 samples. The access time is pretty great compared to the typical seek time of “spinning rust” hard drive platter which averages around 100 MB/s. Essentially a factor of four increase in performance. The seek time on the SSD is .10 msec as opposed to 18.81 msec which is about 180 times faster.
I resisted for a long time going to SSDs because, that seems to be my M.O. on new technology. I am glad that the SSD technology has come down in price. It has greatly improved the performance of this aging all-in-one and extended the life of this machine. The performance improvements of SSDs over HDDs is not in any way a revelation. The point I want to emphasize here is that by putting in an SSD, the machine is far more useful and the user experience is vastly improved. So, rather than chuck the old computer, swap out the Hard Disk Drive with a Solid State Drive.
With all the talk of VPN (Virtual Private Network) services to keep you safe and my general lack of interest in the subject, I was talking to Eric Adams, my co-host on the DLN Xtend podcast about the subject. He was telling me that he was hesitant to recommend any service so he gave me some option to try out. The one I chose, after doing a little reading was Windscribe.
I am new to the VPN game so I want to be careful in saying, I am recommending this as the perfect solution but rather demonstrating how I set it up and how I am using it on my openSUSE Tumbleweed system.
I know that my employer requires me to VPN in to do any real work so even they recognize the value of a good VPN, so maybe I should too. How often do I plan to use it? Not all that often, really. Maybe a few times a month, specifically when I am using an internet access point that I do not trust. I will especially use it if the access point is has “xfinity” in the SSID as I have little to no trust for them.
I appreciate how simple this is to use and should I get to the point where I am pushing my 10 GiB per month limit, I will go all in on an annual subscription. It’s not that expensive to put up one extra line of defense, especially one as convenient as this.
FerenOS is the current BDLL Challenge. I find that I really appreciate the work that goes into Feren OS. It is certainly worth a spin for anyone, whether you are a “KDE Fan” or not. I do think that the departure from using Cinnamon as the base has been good for the overall experience, not because I am a huge fan of Plasma, which I am, but that it seems to have opened up a lot more creative flexibility to the project.
My review of Feren is still forthcoming, at the time of recording but I find that the experience is great. It feels like a polished well thought out product that pays attention to the finer details. It’s certainly worth a visit.
Bottom Line Up Front: FerenOS (2020) is simply fantastic. The way you are greeted and guided through your setup is brilliant. I am not keen on every design decision but that matters not as I am never keen on every design decisions, to include my own. FerenOS is going for a look that is uniquely its own and is not afraid to experiment, cross toolkit boundaries and stray from the normal. I appreciate the design decisions, more than any other “boutique” distribution that I have seen in a long while. Do I like all of them? No. Would I choose many of these? Also, No. But I think they do look great, make for an enjoyable experience, just not one I necessarily prefer.

I have forgotten about this and if I have, maybe you have too. Some of the interesting games I see are”
0 A.D. – A Real-Time Strategy Game of Ancient Warfare
Armagetron – A motorcycle battle game in the theme of Tron
Barbie Seahorse Adventures – A 2d Pixelart platformer that I can admit I tried many years ago and it was rather enjoyable.
Endless Sky – A space exploration and combat game
Extreme Tux Racer – A high speed arctic racing game based on Tux Racer.
There are many more to check out that I truly find enjoyable.
Computer History Retrospective
The 1983 the then “modern” word processor was already adding efficiency to the Newspaper Industry where columnists could write in a remote location, type, edit and transmit content, via modem to the newspaper or where books could be written, stored on disks and transmitted to the publisher when it was completed.
Even in 1983, Correcting Spelling and stylistic devices were already being employed. While some winters had disagreement with the affect on written language by these technologies and that computers will promote dry, bland writing by diluting an individual style. Others claimed that it improves writing ability as the amount of computer intervention is at the writers discretion.
It was even suggested by Paul Schindler that, like a car, you should try a Word Processor before you buy it which was a good idea because of the price.
Wordvision $50-$70 range Wordstar up to $500
Paul Schindler gives advice about not needing to buy a 32bit “super micro” if all you are going to do is word process. I couldn’t help but relate that to modern computer thoughts. Don’t buy a computer that has more power than you need but at the same time, I would argue that it isn’t always the case
It is interesting to point out that the most powerful tool in word processing and analyzing words was on a Unix System V.
Watching this episode of “The Computer Chronicles” has really made me appreciate the state of word processing today. LibreOffice, AbiWord or any of the other word processing applications out there are available to me without any expectation of monetary exchange. Though, if you would like these applications to continue to exist, it would benefit you to donate to them.
This whole thing was an incredibly interesting retrospective on how differences and similarities of computer or automated technologies employed in the 1980s as compared to today. We are very fortunate that the open source software availability has made day to day computing far less expensive and I would say, far more productive.
I recently posted about my computer build. In short, this is a computer build on parts that are in no way considered top of the line. They are all quite old and that did pose a few problems. One, this motherboard would not boot from a software RAID pool. I was able to bootstrap the BTRFS RAID pool with a separate drive and root partition. It did add some complexity to my system but I think it works out okay.
Building a system is something I have wanted to do for quite some time. As in, several years but time, finances and decision vapor-lock had kept me from it. What pushed me over was a fortuitous conversation at a Christmas gathering last year, I struck a nerdy conversation, with a computer store owner that ultimately gave me this giant Thermaltake case without a motherboard and a few weeks later, another fortuitous happening where I was given a bunch of old computer equipment and an AM3 motherboard was among the rest of the aged equipment which drove the rest of the build. My course of action was to stuff the most memory and fastest processor in that which is what I did and I am happy with it. I am not going to belabor that process as I have talked about it before and I have a link you can follow if you are interested in those details.
As a result of this, I had tons of fun, it was a great learning experience and that same guy gave me another case, not as big but far more robust in design with a water cooler. I now want to build another machine but I am thinking a more pure gaming machine and leave this current machine to be my server workstation. I don’t know when I would get to this but I think this one will be a project I do with my kids. Use it as a teaching opportunity and turn it into a kind of family event. Currently, the machine has a Core 2 Duo CPU platform of some kind. I think I would probably do another AMD build, something newer that can take advantage of these new fancy CPUs coming out. I still wouldn’t go bleeding edge but certainly something closer than what I have now.
I have fully evaluated my use of Emby and given a little write up on it. I described the installation process, setting it up, importing my media files and so forth. I want to just summarize the highlights and the lowlights of my experience before I begin my next testing of Plex.
What I like
Emby is super easy to set up. It is nothing more than copying one line into a terminal and executing it. It is super simple and the script also seems to, at least on the version I installed, start and enable the emby-server service.
It’s super easy to add media libraries to Emby. The wizard walks you through it in the beginning and if you want to add additional libraries, that is very easy to do through the configuration tool.
Streams to just about everything in the house. Essentially, if it has a browser, you have access to the Emby server. I haven’t had any issues with the system in the approximately five weeks I have been using it.
Updating the metadata and identity of any movies is as easy as a click and search. You can change the cover images and so forth. Some of the movies I have ripped haven’t always been detected completely correctly. For example, there are three different Grinch movies and I had to manually define which decade they came from. It was super easy.
The Android application works quite nicely. I am actually impressed with the ease of use of the application. It also has quite the fine polish to it as well.
What I don’t like
This was an open source project that went closed source. I sort of have an issue with that and I am not alone with that assessment. It was at that point that Jellyfin was forked from Emby which is what makes me incredibly interested in Jellyfin.
I can’t stream to my Wii, though I don’t really blame the project for not supporting a 14 year old game console. There isn’t an app on the Homebrew channel though at the time of writing, I realized that there is a browser on the Wii so perhaps more investigation is needed. I will update this paragraph with any new information I learn as I investigate that possibility.
Updates will have to be done manually. The server does say it needs to be updated and to do so requires the same step as installation. That is really the only clunky part about this whole setup.
Emby is pretty great. Regardless of what I do not like about it. It is a great experience. If you are undecided on your media server and have a desire to try the different options, this is a good one. If this was my only option, I could easily get along fine with it. Since I have two others, I will check those out too.
I highly recommend you try out Emby as the shortcomings are nitpick issues. I don’t like that it went closed source but the project, closed or open, is sound. It is a great, well polished, experience.
This is my first media server review. I will have follow up articles to this in the near future. If there are any inaccuracies or areas I need to revisit, please let me know and I will take the time to make updates.
It did take me a quick start tutorial to get going. I do kind of wish there were more instructions on how to do things that weren’t in video form. I like video and all but it is too slow to go through. I would rather scan down a page and see little clips of how each effect is done on it’s own. I suppose there is nothing stopping me from doing that.
Kdenlive is easy to just get going with it. Once you understand the work flow, dump your videos, music, pictures and such in the “pot-o-media” and you are off to the races.
What I Like
Kdenlive is incredibly stable and reliable. Crashing is incredibly rare. I have spent many hours at a time editing and not once has Kdenlive crashed. In all fairness, it’s been hours of editing because I am not very good at it. I have used and rendered video on both my Dell Latitude E6440 and my “new” AMD FX-9590 system with out any glitching or issues. I am impressed by the stability and smooth operation of Kdenlive on openSUSE Tumbleweed.
The user interface of Kdenlive makes sense. The shortcuts, the ease of defining the effects and transition as well as previewing the video makes for an easy and enjoyable video editing experience. Even the scrolling across the timeline or through the tracks, all just makes intuitive sense.
The options for rendering videos or even just audio has a straight forward interface that makes it quite clear what is happening when you start that render. Also, when you start the render, you can continue to use Kdenlive. It does not lock you out of the application.
What I Don’t Like
The text editor for title screens is a bit ropey. The cursor indicator isn’t always visible so I often have to make special effort to get to the right location which includes some delete and retype from time to time. The use of it is not as much fun as the rest of the application.
Not so much a fault of the application but doing video editing really needs more screen real-estate. One 1080p screen is not enough. Not the fault of the application but it is hard to see and read everything going on without excessive scrolling.
Kdenlive is a great application with a lot more features than I know how to even use. I don’t do any complex video editing. I don’t have good video equipment so I don’t have a real high level of motivation to create a lot of video content at this time. You can only polish a turd so much and I am often not happy with the video I shoot. I am happy, however, with what I can do with the video in Kdenlive. It does make turning the lack-luster video into barely acceptable video content. Editing with Kdenlive is easy to use and is enjoyable to turn the mess I start with into something more usable. I would like to make more excuses to do more video content because the great user experience Kdenlive provides.
I have heard of people complain that Kdenlive isn’t stable, well, that is a bunch of hooey. Kdenlive on openSUSE Tumbleweed works fantastically well without any crashing. I am very thankful for fantastic packaging and QA process from the openSUSE Project and I am very grateful for every programmer that has had a hand in every piece of this, from the Linux kernel to the Plasma desktop to the application itself. Thank you for all your time and efforts.
Linux Powered Festive Lights
Move from Christmastime to Wintertime. One of those I like a lot more than the other but by having “winter lights” it brightens up the space around me and pushes that gray, cold, dark sadness away. Thanks Linux!
Anything multi-colored and Christmas specific has been taken down. The strands of multicolor lights on my porch have been replaced by blue lights. The wreath and Santa are down but in Santa’s place is an inflatable snowman. Everyting is now white and blue around my house. Not as much fun as Christmastime but I think there is a rule about how much fun you can have at any point in time of the year and I don’t want to over indulge in it. I have to keep it for the designated times, be seasonally appropriate.
I have purchased a few other little things to add to my display. What can I say, I enjoy talking about it. More on that in the future.
Of the three Universal package installers, AppImage is one of them. Historically, it has been my least favorite due to the more squirrely way of managing each application. Essentially, you had these files are scattered about your file system or shoved in a folder some place and if you wanted to put them in the menu, you had to do it manually. When you downloaded an update, because not all AppImages support updating, you had to recreate or edit the menu entry and lacks all sense of intuitiveness. It is just incredibly primative
Some AppImages would integrate themselves into your menu system and even perform their own updates. Most of them, however, do not implement those nice little features. Another step, before launching it, having to modify the properties to make it executable. Not a difficult step but it was another step that made it feel a little clunky to use. Combine all these anti-features together and it was my least favorite Universal package. Sill grateful, just least interested.
Step in AppImageLauncher. This throws a significant change in the Universal Package landscape. I have been favoring Snaps for many reasons: the central repository, the ease-of-use in the command line or graphical tools (I used the command line), automatic updates and vast selection of applications has made it my first stop in the Universal Package route. The next has been Flatpak. It has a pseudo Central Repository, nothing official, it integrates nicely with Plasma’s Application Explorer, Discover. Flatpak has recently been better about automatic updates and does a fantastic job of theming itself automatically to your desktop settings.
Lastly has been AppImages because of the rather ad-hoc nature and disjointed desktop experience they have provided. They would respect your desktop themes and are a great non-committal way to try an application but lacked a convenient and clean way to access them. I have used AppImageLauncher for such a short period of time but it is a game changer as far as desktop experience is concerned. The ease of installation and removal of your application in the menu and the automatic organization makes for a purposefully integrated experience. You really can’t tell that you are using an AppImage unless you are doing a right click in the menu entry. Now, on my openSUSE systems, AppImage is a first-class citizen beside my system package manager (RPMs), Snaps, or Flatpak. 2020 is starting of great in the software world.
So why would you use the AUR?

Something that doesn’t seem to get enough attention is the BDLL Discourse Forum. There is a lot of great discussion going on there, not just because I am dumping everything I am working on there but because it is a great place to get help, talk about your Linuxy experiences and just have great conversation about interesting things in tech.
The Linux Half Top was a thread submitted by Steve (Mowest). He had a broken laptop screen and instead of dumping $100 plus into the machine for a new screen and touch panel, he took the screen off entirely, added an HDMI to VGA adapter. Steve gave credit to another community member Dalton Durst for the idea. It reminded Sleepy Eyes Vince of the Commodore 64 where the computer was in the keyboard and just needed a screen.
The whole idea was brilliant, simply brilliant and was an exercise in problem solving by looking for an entirely different solution. Well done.
I highly recommend you take a trip to the BDLL Discourse for some very interesting discussion, discoveries and ideas.

Computer History Retrospective
I was recently watching an episode of Computer Chronicles that covered the idea of “Simulator Software” recorded in 1983. They talked of the flight simulators of the time, simulations of architecture and urban design. Even in the 1980s they were saving money by doing virtual testing of an environment before you spend the time and money on the real thing.
There was a flight simulator used by the military in the early 1980s that by today’s standards, not so great but if I were running that on an Amiga or x86 based PC in the mid-90s, it would have been pretty darn impressive yet.
It is interesting to see now, the graphics capabilities have advanced. Any one modern graphics card has such incredible graphical capabilities, delivering fantastic realism. It’s something that is pretty amazing if you stop and think about it.
I can’t help but wonder how those ideas were sold at the time to punch information into a computer that by all accounts is not all that capable of calculating the vast sets of variables that are done today. Today, there is so much more that can be done with finite element analysis in software that you don’t have to pay for. Examples of this are, FreeCAD and Fusion360, one an open source application, the second a close source application but free to use for hobbyists.
This is a great episode of the Computer Chronicles if you are interested in seeing the early development of computer simulation in the early 80s. The excitement around it is pretty fascinating and we can thank these people for pushing the technology from which we enjoy the fruits today.
Fusion 360 is a CAD / CAM application with finite element analysis capabilities. I was going through the Autodesk forums and read a lot of chatter about their position on the Linux client. It appears that for several years, there have been requests but there is no plan to support it.
One user gave a fantastic well thought out, logical reason for building Fusion 360 to work in Linux and he gave the typical reasons for not doing so with answers:
the management sees not enough customers here. It’s a question about cost/income ratio.
I think if done right, there are not much costs (keyword continuous integration)
Number of potential customers. Linux users need to raise there hand and write to Autodesk, so that they can see, there are potential customers. Linux leads already on the server market, and on embedded devices, smart phones and tablets (if you count Android as Linux).
On the desktop, Windows is still the dominating system (88%), Mac (9%), Linux (2%). But this is for the average user, this doesn’t need to be true for engineers and makers using CAD software.
I have no statistic here, but I personally have never seen engineers working on Mac. But I have seen many engineers, software developers and scientists that work on Linux.
Linux users are willing to Beta test and are able to generally figure things out for themselves.
There were a lot of hostile responses from Windows users that were just… hostile. I do think that is a large part of the untold story. There are those that point to Linux and talk of the technological elitism but I don’t think that is a behavior that exclusive to Linux users at all. I can refer to this post for evidence otherwise.
Even though Autodesk has stated that they have no plans to support Linux, it is always with the caveat that of “at this time.” I still have hope that Linux will be supported in the future. It’s inevitable as there are a larger percentage of Linux users in the engineering field, Autodesk does support Linux on the Maya application and since there are more and more professional tools on Linux, I truly believe it will follow.
It took me far too long to complete the write up and video but I must say that the tiling features in Plasma are pretty fantastic. I spent this past weekend doing a lot of administrative work for another job of mine and the tiling manipulation of windows and desktop navigation made the tasks far less painful than they have been historically. I have to emphasis once again that it is important to have key combinations that make sense that are easy to remember that can are quickly intuitive to you.
I made a little video about this with Kdenlive and put it on YouTube. I had a less than stellar comment about my production quality. For that, I can say, I’ll try better next time.
I did a post this last week on my use of Linux in the kitchen. I did appreciate a lot of the great feedback II received from this. I don’t want to understate, at all the value of technology in the kitchen. It is not at all a strange science experiment being shoe-horned into a role in which it doesn’t make sense. Linux and the array of tools make several kitchen tasks more efficiently completed.
For my case, the right hardware was an important part of the implementation as I have a very limited amount of counter space. There were already several software applications I had been using, I just happen to further expand how I had been using them.
How it recently made the Christmas season more efficient…
What would improve Linux in the Kitchen is going to take some real effort on my part. Most of these things will be aided by single board computers or IoT like devices. I need more metrics in order to improve my results when baking. Improved inventory management, improved meal planning. All but the last one will take some serious work and effort in order to implement.

Fedora 31 challenge. Lot of people were rough on it and in some ways I understand but in others I do not. I have used Fedora periodically and I have always found it to be an enjoyable experience. Fedora is a lot more like getting a Lego set with some instructions than it is a ready-made product. I look at Fedora as being a more industrial grade Linux system that you implement for a specific feature. While distributions from the Ubuntu flavors are more like products that are ready to be used that focus on the out-of-box experience. All the flavors of Linux have a place and a target audience. Everyone is entitled to their own opinions about a distribution experience but I think it is almost a bit unfair to evaluate Fedora in the same way you would evaluate an Ubuntu.
I have decided to use Fedora’s Plasma edition and I am going to give it a fair, but biased, review. My expectations are very focused. I don’t need the “last mile” type polish, nor do I expect that from a Fedora or an openSUSE for that matter. What I do expect is something very easy to work with and mold to my wishes.
openSUSE does a great Plasma. I don’t mean out-of-the-box perfect for my needs. No distribution should ever target me as the core user, that would be tremendously silly. I am an edge case and I am never satisfied, I am a moving target of requirements and expectations for what I want as my personal workspace. I would be a high maintenance target for a perfect out-of-box experience.
wiggle (1.1 -> 1.2) a program for applying patches that ‘patch’ cannot apply due to conflicting changes in the original. Wiggle will always apply all changes in the patch to the original. If it cannot find a way to cleanly apply a patch, it inserts it in the original in a manner similar to ‘merge’ and reports an unresolvable conflict.
bubblewrap (0.3.3 -> 0.4.0) The biggest feature in this release is the support for joining existing user and pid namespaces. This doesn’t work in the setuid mode (at the moment). Other changes include Stores namespace info in status json, In setuid mode pid 1 is now marked dumpable also now build with musl libc. gthumb (3.8.2 -> 3.8.3)
gnome-shell (3.34.2+0 -> 3.34.2+2): polkitAgent, Only set key focus to password entry after opening dialog. The keyboard now stops accessing deprecated actor property. libnl3 (3.4 -> 3.5.0) * xfrmi: introduce XFRM interfaces support xfrm: fix memory corruption (dangling pointer) mypy (0.720 -> 0.750) More Precise Error Locations and the daemon is No Longer Experimental python-Sphinx (2.2.2 -> 2.3.1) python-Sphinx-test (2.2.2 -> 2.3.1) python-jedi (0.15.1 -> 0.15.2) python-mysqlclient python-parso (0.5.1 -> 0.5.2) python-pybind11 (2.4.2 -> 2.4.3) python-typeshed (0.0.1+git.1562136779.4af283e1 -> 0.0.1+git.20191227.21a9e696)
wireshark (3.0.7 -> 3.2.0) bug fixes and updated protocol support as listed
Firefox (70.0.1 > 71.0) Improvements to Lockwise, integrated password manager, More information about Enhanced Tracking Protection in action, Native MP3 decoding on Windows, Linux, and macOS, Configuration page (about:config) reimplemented in HTML, New kiosk mode functionality, which allows maximum screen space for customer-facing displays. Numerous CVEs were addressed relating to memory.
I think we often take for granted the multimedia capabilities of computers today. It seems like someone is always harping about PulseAudio on Linux. I’d say they are likely not using the right distribution, by that I mean openSUSE, I don’t have these issues. The purpose of the section is not to tout the superiority of my favorite operating system when it comes to audio subsystem, rather, it is to talk and reflect about how great we have it today with all things audio on modern computers.
In 1983, the state of digital music was not as rich as it is today. We can enjoy a virtually endless supply of content never before available in human history. Let’s go back in time to an era when the Commodore 64 was the pinnacle in home computer audio. Where audio was entirely programmed, limited to 4 wave forms of sawtooth, triangle, pulse and noise. A multi-mode filter featuring low-pass, high-pass and band pass outputs and three volume controls of attack / decay / sustain / release (ASDR) for each audio oscillator and a few other things I barely understand. Regardless, the capabilities were limited and synthesizing voice was an incredible undertaking that took years of work long after the chip was in the wild. This was one of the first polyphonic sound chips on the consumer market that, to this day, is held in high regard and many still like the sounds this chip produces.
All this said, this was very interesting record of computer generated music that is certainly worth a listen. I find the experimentation and musical education tools used in this perod incredibly fascinating. Today, things are very different. Musical composers and artists use computers in music production and to do so otherwise would likely be considered insane. I now wonder if individuals in the 80s that pushed the art and science of computers in music were considered insane by their peers.
Bought a turkey to smoke for Thanksgiving. I had to buy a 5 gallon bucket to brine the thing in. Using a basic brine of brown sugar and salt. I realized that I don’t have a large enough smoker to hold the turkey whole so my solution is to cut it in half so that I can put it on two of the racks.
What I learned
My smoker thermometer is probably wrong
I would have been wise to swap the halves of the bird sometime through the smoking process
I used to much wood so it was a bit too smokey tasting
Those turkey bones made for some great post-Thanksgiving soup
Next turkey should be a bit smaller or just do a couple chickens instead
What would be really great is to have a smoker that has some sensors like temperature, humidity, particulate matter and a couple probes to put in various places in the meat so that I can get better data on the cooking process
Linux Powered Christmas Lights
I have wanted to some kind of computer controlled Christmas lights since I first saw this light display on YouTube to the tune from the Trans-Siberian Orchastra, “Wizards of Winter.” Since then, this has been something I wanted to do. This was the year that I finally did it and this is what I used.
BeagleBone Black rev C
Kulp Lights F8-B “Cape” that controls the pixel lights
8 local ports for strings of lights
Each string can have approximately 700 pixels
Multiple expansion options
Pixel2Things AC board to power the traditional AC strings of lights and the blow up Santa and Painfully bright White Christmas tree
12v 30Amp Power supply
ABS Electrical Junction box enclosure
10 Pair of Ray Wu connectors to build extension cables and to wire into the F8-B
200 ft of 18 AWG 3 conductor cable to build extension cables
500 ft of 18 AWG 2 conductor cable for power injection, although, I didn’t end up needing it.
8, two conductor extension cords from the hardware store for the Pixel2Things AC devices, the traditional department store lights and the blow up Santa
1, 40 ft, 3 conductor extension cord for powering the control box and for extra wire as needed
Currently running 1148 pixels totaling 3444 light channels
xlights software AppImage which works very well in openSUSE. Using it not tied to music but just as an animation.
Turning some of my “Christmas Lights” into all the holidays lights.
Next year I will be building some props, candy canes, arches and Christmas trees, add a low powered FM transmitter to do light shows to music but not so much that my neighbors will want to burn my house down

Working through evaluating the Ubuntu 19.10 releases. I’m impressed with the Ubuntu Proper release. It is a great project that has so many high quality derivatives.
Ubuntu Proper (GNOME)
I am going to just say that Ubuntu has my favorite expression of GNOME. The Competitive advantage of Ubuntu GNOME is the clean experience and the additional features that just make sense for a typical desktop user
A solid experience and it just doesn’t disappoint. You can choose between the different desktop paradigms of Windows Like, Mac Like, and Unity Like. It’s such a smart Desktop and frankly I think this should be the Ubuntu Proper experience, but that is my opinion.
The LXQt desktop with the best out of box polish. There are some other things I would polish out on it, specifically, to drop openbox as the window manager and use Kwin but that is easily done for any user. In fact, I did a little write up on it.
A great Plasma desktop experience and although it has some really great defaults, I still prefer some of the other integration better on openSUSE. Specifically that Firefox uses the Plasma file dialog box instead of the clunky GTK version. Since the default layout is not a big deal to me as that is easily changed and I have been doing so since the KDE 3 days, there isn’t a great reason to choose Kubuntu over an openSUSE Plasma. However, I will say, it is my favorite of the Ubuntu flavors. They just happen to do Plasma justice and for someone new to Linux that wants a premium Linux experience, this would be a candidate to send them there.
Xfce based Ubuntu. I didn’t actually try it but since I know what I am getting with Ubuntu and I know what I am getting with Xfce, you just can’t go wrong with it. For those that like the Xfce experience and want to try their hand in the Ubuntu world, this is a good place to go.
