    I've also been playing Space Age since it released, and I found Gleba to be quite enjoyable once I figured out how to start up a nutrient/bioflux feedback loop. The rest of the game encourages making a bunch of resources and stockpiling them for whatever you are building next, so Gleba was a pleasant change of pace for me. The general design philosophy for the planet is that if you harvest/create a resource you either need to use it as soon as possible, or have a plan for dealing with spoilage if you don't need it.

    I've written up a description of how I ended up setting up my Gleba base below, focusing mostly on my general design principles of how to keep things from backing up and stopping production. Hopefully you will find the below helpful to you when you set out to attempt your second Gleba base.

    My Gleba Design Philosophy (spoilers for a way to solve Gleba production)

    I started with a mostly logistics bot layout, and I actually found it was much easier for me when I used belts for things, as you can just add splitters that send all your spoilage to a waste belt that leads to an incinerator. You also get to see everywhere that things are spoiling so it's easier to track down bottlenecks visually than it is to figure out where the 10k of spoilage in your logistic storage came from.

    The main change for me on Gleba is that instead of trying to make one giant system that does everything like my Nauvis main base, I instead made a bunch of small specialized production loops that can be duplicated as needed to output a specific product. Fruits go in, seeds and useful items come out, and everything I don't need immediately for that loop gets burned at the end of the line. There will always be more fruit coming in as long as you're processing it and shipping seeds back to the farms, so burning the excess items is totally free and it keeps things from getting backed up. If you find you're running out of fruit, you just go find a new soil patch and plant more trees.

    The back end of each of my production loops changes depending on what I'm making, but they all start with the same basic system in the front. I will take tree fruits as an input and use it to make bioflux. I then use the bioflux to make nutrients. I do need to manually feed nutrients into the biolabs to start the loop up, but once it gets going, as long as I'm processing all the fruit that gets picked and sending the seeds back to the tree farms, it will run indefinitely and I'll never run out of nutrients/bioflux again.

    Once I have the biolabs producing nutrients from bioflux, I then use that basic setup setup of fruits to bioflux to nutrients to sustain a constantly running loop of nutrients and bioflux that supplies all the machines in the production loop for whatever else I'm producing, be it iron/copper bacteria, science, petroleum products, etc. As long as both fruits keep coming in to make more bioflux, and the line doesn't get backed up, it will run forever. I will add a couple more Mash or Jelly labs depending on what the things I'm building down the line will need, but everything starts with the sustainable fruits to nutrient/bioflux loop.

    To keep things from backing up and stopping production, my bioflux/nutrient loop always has a splitter or two that filters out any spoilage and sends it down a waste belt back to an incinerator. If any belt I'm using isn't looping, I just add a filtered output (like a splitter or inserter) at the last belt tile that will remove any spoilage as it collects at the end of the belt and feed it to the waste belt system.

    The same is true for machines with anything spoilable in them. If a biolab gets backed up for a bit, the nutrients fueling it turn into spoilage even if nothing else in the machine can spoil, so I make sure every machine has a filtered inserter that will remove spoilage and add it to the waste belt/incinerator system. The spoilage is never high volume, so long inserters can handle offloading spoilage without hurting throughput. As long as waste disposal is handled at every machine and at the end of belt lines (or via splitters in looping belts), things will run forever.

    One potential non-spoilage blockage that got me was seeds. If you're belting seeds back to your tree farms, you'll eventually end up filling up the seed belt since you get more seeds back than you need, so it's a good idea to check if the belt is backed up and burn the excess seeds before they reach your production loops. If the seed output on a biolab is full, that can halt your bioflux production and stop processing fruit.

    I'm a current GW2 player, and this expansion is a new thing ANet is trying. It's supposed bigger than a living world season, but smaller than the previous 3 expansions. They are also doing a slow release of content, so initially there will be two new maps and some story content, and over the next while there will be more story chapters released and a third new map.

    In general, I am tentatively excited for the new changes, including new weapons for existing classes, new PVE legendary armor that's not locked behind raids, and new story content. While I have unlocked legendary armor from raiding with my guild, having a way to get it without needing to grind raids every week for currency is appealing for acquiring my second two sets. I'm also excited about the changes to the skyscale mount, making it easier to get and upgrading existing flying mounts to work with leyline gliding and updrafts.

    for the C implementation if you're setting those pins at compile time anyways are you sure the compiler isn't just doing away with those runtime checks? Or does your HAL interface require you to set everything up at runtime?

    There's a very good chance that the compiler is smart enough to remove some checks, but I haven't really looked into it very thoroughly. It's been a while since I was working on something where the timing of digital pin switching mattered, so my memory is a bit fuzzy. The last time I remember running quantifiable tests, I think it was on an Teensy 3.1 or 3.2 board (can't remember which), and using a library with set_high(pin_number) or set_low(pin_number) functions in some platformio library, it came out to be about 5 times slower than just manually setting the register bit. It has been a while, so I may be recalling things a bit off, but that was the gist of it.

    The main takeaway, for me at least, is that while it is possible to make things work the same way in C/C++, it's nice that the default way in rust's embedded-hal is also the way with the least overhead.

    One area that I can see being hard for Rust to break into is replacing embedded C.

    Based on the embedded developers I know and interact with, I can definitely agree that it's going to be an uphill battle to get them to change how they do just about anything. Using C++ features in embedded development is still frowned upon by most of the embedded developers I know despite widespread support, and almost no downsides provided you use an appropriate subset of C++ that is embedded-friendly (i.e., no major standard libraries, nothing that heavily makes use of the heap, etc.). While I personally love rust for embedded development, trying to convince the embedded world at large to move away from C is going to take a great deal of effort.

    The subset of C they're working in -- no heap allocations and linted to the MISRA C standard -- already eliminates large classes of bugs rust addresses. I don't know if the large jump in language complexity and features is going to be an added benefit for them.

    I've actually been getting very into embedded rust programming of late, and I find that while things like avoiding the heap are indeed helpful in avoiding bugs, the greatest benefit of embedded rust is to practically guarantee that race conditions and other memory issues are not possible at compile time, with no run-time overhead. In my past embedded C/C++ projects, debugging race conditions has been extremely difficult and time consuming, due to their intermittent, ephemeral nature. I'll gladly trade a bit of language complexity to avoid the possibility of these types of bugs being possible in the first place.

    I also feel, as someone coming from a programming background of mostly embedded C/C++ and getting into rust, that people with the embedded C mindset are uniquely suited to understanding the memory safety features of rust such as the borrow checker. Embedded C programmers are already intimately familiar with having to manage memory at a low level, and the rust compiler just enforces an explicit, rigid framework to allow this to happen. I work with a local hackerspace to teach people programming, and the ones who already know C have been most receptive to learning rust concepts, as opposed to those who are more familiar with languages like javascript and python, that abstract away low level memory management to a much greater extent.

    Another reason that I feel rust is well suited to embedded development is that one of its big selling points is its zero-cost abstraction model. This allows for syntax used in higher level, more abstracted languages, but it doesn't cost anything in terms of processing time or memory.

    A good example of this being an advantage for embedded programming is setting a pin as an output, and toggling it. In a typical embedded C hal, there would usually be a function that has to check if a pin is configured as an output before setting it at runtime. This costs a small bit of time every time the pin is toggled.

    With embedded rust's model, each pin exists as a single entity in a peripheral struct, so due to the borrow-checker and compiler guarantees, there can only ever be one reference to that pin in use at any given time. When you want to configure a generic pin as an output, the pin is returned as a new type that has implemented a trait with functions to allow you to toggle the pin on and off. Since the pin is a singleton, and it's been transformed into an output pin type, it is impossible for it to be configured as an input now, and therefore you no longer need to check if it's valid to toggle the pin at runtime.

    While it is possible to explicitly configure embedded C to work in the same manner, it would require you to explicitly code your own compile-time types and checks, instead of using the standard tools provided by a typical manufacturer's HAL libraries. With embedded rust, there's a generally an agreed upon standard way of doing things as outlined in the embedded rust book, so changing architectures is also made simpler, and still results in the same zero-cost abstraction model working on every architecture.

    I will readily admit that the embedded rust ecosystem is still a long way from being a ready replacement for C, especially on less-popular architectures. Rust's default use of LLVM instead of gcc for compiling binaries immediately precludes many architectures not supported by LLVM. A rust gcc backend which will allow support for every architecture gcc supports is in the works but it's still a fair ways off. Even once the gcc backend is implemented, it will still be a while before embedded-hal libraries can be implemented for architectures not currently supported by LLVM.

    As part of my current project linked above, I found that the rust hal for the chip I am using is far from complete, and I've been working alongside my project to help implement the hal as I go. Many other embedded ecosystems are in a similar state of not-yet-complete-or-stable. This is definitely a valid reason that commercial embedded shops would want to avoid rust at this time.

    Overall, I feel that rust offers significant advantages in the embedded space, as the memory safety problems rust is fundamentally trying to solve as a language are the same problems that embedded C developers have had to manually address up to this point. The embedded rust ecosystem is still in its infancy, but it is growing rapidly, and I feel that eventually it will be a popular alternative to embedded C development.

    When I clicked on this video, I expected some developer that got a demo version of the steam deck breaking their NDA and doing a tear-down anyways. I was pleasantly surprised to find out that the video came directly from Valve. This just makes me even more excited about this product, as I saw nothing but normal fillips head screws, and nothing unnecessarily glued down inside the device.

    Sure, it's not the easiest thing to perform maintenance on, but it's at least possible. not only that, the company making it had produced the video going over potential pitfalls and issues that may occur when taking one apart. That's practically unheard of for almost any other gaming devices that have existed in my lifetime. Props to Valve for backing up their 'it's yours, you can do anything you want with it' statements.

    I believe that when I was making my decision on which bulbs to buy, I was highly influenced by this review video. I haven't ever used Hue bulbs myself, so I don't know about their shortcomings / advantages outside of other people's reviews on the internet. I initially bought a couple of the sengled bulbs to test, and I was happy with the results, so I've stuck with them for my whole house. If you've already bought some hue bulbs and a hub, you can integrate the bulbs you already have into Home Assistant, and then either get more hue bulbs or another brand, and control them all together from one interface.

    Or if you want complete control, you can invest some time and get Home Assistant up and running. You can completely customize it, but it is a lot of up front time investment.

    I've gone down the Home Assistant path for RGB lighting throughout my house. I've got Home Assistant OS Installed on a Raspberry Pi 4 with an SSD. I use a HUSBZB-1 dongle which allows communication with Z-Wave and Zigbee devices. All the bulbs in my house are Sengled Zigbee RGB Bulbs (make sure not to get the bluetooth only ones that only work with Alexa devices, you need the more expensive zigbee bulbs), and I've had no issues with responsiveness or disconnecting bulbs. On the same Zigbee network I've got some Ikea Fyrtur roller shades, and on Z-Wave I have several Inovelli smart switches as well, all running off the one HUSBZB-1 dongle. All in all I've currently got about 16 Z-Wave devices and 45 zigbee devices.

    With HomeAssistant you can do lots of neat things like set up scenes and toggle them with switches from a web interface or phone app. One scene I particularly like is 'theater mode' for my living room, which will close the curtains and dim the all the lights in the room at the flip of a switch. I've also got scenes set up to turn all the lights off completely when I'm leaving the house or going to bed, or to turn them all on at full brightness when I'm cleaning.

    As @JXM mentioned, it can be pretty technically complex to get everything set up the way you want. I've got a fair bit of networking, system administration, and general programming experience so it definitely made sense for me to go with this route, as I highly value the flexibility, ability to combine different technologies, and complete local control over my devices.

    If you feel you're up to the technical challenge of setting up a Home Assistant server, I highly recommend it. It won't be the fastest or easiest way to control light bulbs, but it'd definitely among the most versatile and customizable.

    I picked up the Halo Master Chief Collection on steamrecently, and I have now played the Halo Reach campaign for the first time, and I'm making my way through Halo CE this week.

    Reach was a pretty solid game in terms of gameplay, especially since prior to playing reach, I had only played the original Halo back on the xbox. The story wasn't the most engaging for me, and it felt like they were referring to a bunch people and things I didn't know about with little to no explanation. Hopefully the other games in the series will fill in the gaps in my knowledge and may make me like the story more in hindsight.

    The original Halo has been fun and somewhat nostalgic for me, but as I play through the later missions for the first time in over15 years, I'm finding the game much more repetitive and uninteresting than I remember. It feels like every room and hallway is the same as the previous one, and the only way to tell I'm still moving forward is if new enemies are spawning when I enter the same room full of the same few enemies for the 15th time this level. I've honestly forgotten how the game ends, so I don't know how much longer the backtracking and repetitiveness will continue, but hopefully the end game will at least take me to somewhere new.

    All things considered, I'm glad I am able to play reach and the original game again on a PC with updated graphics, and I look forward to seeing what happens in the future entries in the series as they are released.

    I don't see it this way at all. I'm a human, sharing a planet with a bunch of other humans. I will never have children, but that doesn't mean I'm willing to be shitty for personal gain even though I don't have any children that may be effected by it. I will be effected by that shitty behavior, as will my friends, and family, and their children.

    I've got empathy for the other life on this planet, and I want to see life, including humanity, be able to thrive and continue to exist. Ideally it would be in a sustainable way, where people voluntarily limit the population to a number that the world can support indefinitely. This can be accomplished by educating more people on the costs of having children, and working to make sure that the children that are born are taught what is needed to keep the world sustainable to life.

    As a fellow human living on this planet, I am as responsible for the future of this planet as anyone with children of their own, and having been educated myself I know that even if I am not personally effected, my actions effect the future of the world for everyone I care about, and all those that will come after them. We need to work towards a society where people who think it's okay to be shitty because it doesn't effect them personally can be taught empathy for their fellow humans. Everyone has a stake in the future of this planet, whether they have kids or not, and that responsibility has to be impressed upon us all if we're going to be able to continue to live on this planet.

    I've been working on a project I call the oMIDItone. I took a silly 'instrument' from Japan called an otamatone and decided I would turn it into a MIDI synth. I first made a prototype with just a single otamatone head and realized the range was too limited to make a functional synth that could play a recognizable song. I ended up hacking together a newer version that uses 6 heads at once to allow for it to play music somewhat coherently.

    This month I just finished designing and ordered a new PCB for controlling all 6 heads without all the wires and hacking-it-together of the current version. I'm hoping that if this new PCB works well, I will be able to add servos to control the mouths and make them open and close in time with the music as well.
