Rimuru facing decommissioning

by

Before the holidays, I had the problem that Rimuru would power on in a brain dead state — fans would spin up, most buses would power their components, and so on. But it wouldn’t POST or reach BIOS. Just brain dead. The only way to turn it on or off was the cord and kill switch on the PSU, and trying to hold the power switch on the case would just act like a reset and then total brain death with running fans.

Tried all the good jumping off points: trying to boot off integrated graphics, reseating and walking RAM sticks, etc. Then I took my multimeter to the power supply’s ATX main and CPU power pins, and that seemed to be fine.
At that point the only thing I hadn’t reseated was the CPU, and I’d have to go to Micro Center for fresh thermal gloop anyway if I did that. So, I decided to drop it off and see what they could figure out. Today, I got my machine back. Reseated memory, POSTS. Well, I hoped their touch was more magical than mine. But no dice.
When I had asked, it was unknown if it fresh thermal paste was used, since the guy doing initial processing had tried reseating the CPU and swapping in another of the same model with no luck. Reseated the processor with fresh thermal gloop, and I’ve decided that I am taking a new policy on this. If the CPU cooler is connected and it don’t catch fire, I’m not effing remounting CPU coolers for this–it’s just to much of a pain in the ass in such cramped spaces, and my hands ain’t gettin’ tinier. If I ever build another desktop, there better not be a huge ass heatsinkage over the processor or I think I’m outsourcing to someone fitting that description.
Anyhow, the machine wouldn’t boot and was doing the same thing as when I dropped it off. Gave it a kick and numerous elevated heart rate notifications later while choking on my urge to go Incredible Hulk on the decommissioning, I eventually came back to try a few things.
Tried loading a single RAM channel up and with some fiddly, I got into the OS. To do so, I had to pull the front panel header and rub a nail clipper on the pins. Eventually, I put in the other RAM channel but it didn’t seem to make a difference what I did with the memory.
Depending on how I manually short the reset and power switch pins, the system either hangs as before, goes into brain death, or does a sorta reset and may boot or die.
Fiddling around, I noticed that USB ports may or may not have power. I.e., plug in a keyboard while in BIOS, walk it through the ports toggling num lock, cycle back and what the fuck there’s no power, and then again and now it works. Stuff like that. In some cases the keyboard would draw power enough to light the num lock LED but wouldn’t toggle, and then in some cases it would just be flashing all three LEDs at the top for a while and then go dead.
Anything resembling a “Proper” shutdown like the OS would do leaves the machine brain dead. Have to pull the power and fiddle pins trying to find the right fiddling and timing to boot. Trip the right way and the processor fan cranks and the case fan turns off, and it’s total death until power pull.
So at this point, I think a technician who’s able to test piece by piece and determine what is failed would be needed. That’s beyond my skill without a schematic, and the tiny as hell components to desolder and resolder would make the repair work beyond my ability even if I did have a schematic to work off.
Based on its behavior, I’m inclined to believe the power management chip is screwed up or something has gone awry with the path of power causing it to just “Leak” into systems that should remain unpowered until initialized properly.
To garner a second opinion, I think I may buy one of those PSU tester things to double check my power supply’s readings vs my multimeter. Which basically means, motherboard if it’s not the power supply. If that’s the case, given how much issue it is to get ahold of another motherboard of that model; I may opt to decommission  Rimuru.

One of the things I’ve been wondering for a while now is how the performance of macOS’s EXFAT driver is representative of its peers. It’s notably slower than what you would see in NT, but not so bad until you go from the sequential 1M to random 4K part of my choice benchmarks. Once you hit the randoms, it goes form “I wonder if that’s lack of optimization in the driver, or the I/O system design” to abysmal. But to be fair that is the worst performing metric anywhere, and I’m more interested in the sequential performance. 

Well, having a nice shiny (or should I say, mat?) Samsung T7 Shield that was on sale, I decided to do a little test cycle. EXFAT, FAT32, HFS+, and APFS. This drive is designated for Time Machine duty, so I have no need for it to remain on a interoperable file system.

Using AmorphousDiskMark 4.0.

EXFAT as formatted out of the box:

  RND4KQD1        - 18.33         14.70
APFS as formatted APFS (Case-sensitive), after converting from MBR to GPT from Disk Utility.

  RND4KQD1        - 21.27         13.83

This makes me suspect the performance lossage is more to do with how optimized the FAT drivers are. I should really repeat this with one of my USB flash drives where the performance sucks to begin with, but I don’t want to spend all day on this :^o).

Migration to macOS has been relatively successful so far. Juggling work and dogs and the need to occasionally vegetate, it took a couple weeks to get Shion properly setup.

For me one of the key problems with switching between Mac and PC has been the great modifier shift. The annoying kind of things when I come home and start using Mac shortcuts on my PC, or go to work and start using PC shortcuts on my Mac.

As a work device, my issued MBP has mostly been a case of IDGAF in terms of PC vs Mac. Contemporary OS X and its successors-thus-far, are suitable BSD under the hood with GNU sprinkled on top that it’s basically a non-issue. On Windows, I would be using Windows Subsystem for Linux and SSH. On Mac, well it’s native enough unless it needs to be Linux ELFs. Like NT, it comes with some nice to have GUI software but most of what I care about can be found in the Terminal.

As a home device, I’m finding it fits quite nicely. It does the desktop things that better maintained Linux distributions and Windows systems do, and it provides most of the goodness I’d get out of running FreeBSD or Debian. More importantly I don’t find myself !@#$%ing mixing up the command and control keys ^_^.

Outside of Direct3D based games the majority of software that I care about is cross platform, often with GNU/Linux as the primary platform if one could be defined. So, basically everything I want to run either runs on unix, NT, and Mac systems already; or it’s tied to POSIX APIs longer than Linux and OS X have been around, or it’s unlikely to run on anything that doesn’t do Big Honking DirectX GPUs.

Thus: Rimuru’s intended mission profile is what it was chiefly built for. Playing video games, converting videos, and cursing those times when compiling on NT is a thing. Meanwhile Shion takes over the more secretarial domain of general productivity and desktop computing.

So far, one of the unexpectedly nice things about macOS: I can use my Bluetooth keyboard to wake my MacBook Air. No putzing required. I’d like to assume my desktop could pull that off with fiddling with the power management options for the front ports or motherboard root controller, and/or the Bluetooth USB dongle. But my relationship with NT and things USB/BT is one of pain and suffering, so I’m less inclined to putz with that.

Further iterating my Gateway Station concept, I’ve tossed the Anker 555 in the closet and hooked up a TS4 from CalDigit. Under macOS, I’m finding that this works flawlessly and resolves the “Well, if I just use a second cable for power” issue I observed with the hub.

And then there’s windows (>_<).

One reason that I opted to get the newer TS4 is its love for 10 Gbit/s ports versus the older TS3 Plus. Basically the ports are either rated for 10 Gbit/s USB or 40 Gbit/s TB. Another reason is because of the Thunderbolt 4 / USB 4 capability made me wonder if it would be both backwards and forwards compatible with my desktop.

Migrating All The Things ™ to the CalDigit appears to work well enough for my purposes. I’ve no need for the DisplayPort or Ethernet port on the desktop side. All the USB ports appear to function when plugged into my ASMedia controller, and the only issue observed is that USB drives won’t work. I am unsure if this is due to power negotiation, or drivers. Under macOS, I can basically plug any damn thing in  without issue. Part of me is tempted to swap out the USB 3.1 10 Gbit/s card for a Thunderbolt card, and part of me just does not want to know what the fuck Intel’s NT drivers for that are like ^_^.

When I decided to consider a dock, I decided if I was going to spend the big bucks, which my previous solution was meant to avoid, that I was going to make sure it was cable of being the heart of my desk setup. Such that it could be the Single Point of Truth in connectivity instead of just the break out. That way if the desktop side of the coin proved sufficient I could do that, and if not, I could retain the previous configuration for Gateway Station. Compared to the Windows issues my previous arrangement had, it’s been a bigger issue finding room for the dock on my desk.

Considering that I can use Rimuru’s front panel USB ports when storage drives are required, and have USB-C extension cables that could be routed to the spare port on the ASMedia card, I’m not particularly concerned about my observations so far. My goal with this transition was to have my laptop become the core for the non gaming stuff and relegate my desktop to being focused on gaming. Thus far that’s working. The test that remains is to determine how reliable this turns out on the NT side.

And to remember to turn off my speakers so they don’t fallback to Bluetooth pairing mode, if I leave it connected to Rimuru instead of Shion.

Ahh, sweet, sweet solace of NOT hearing the USB enumeration sound all the fscking time! Swapping the Anker all the things hub out for a simple USB-C that has two pair each of USB-A and USB-C ports resolves the grumbles.

Functionally, I think this is kind of preferable because the extra pieces of the Anker hub that refuse the enumerate when connected to my ASMedia controller, are only needed for the laptop side. I.e., HDMI, Ethernet, and USB-PD. For the tower, I only need the USB ports coalesced into a one cable swap over.

I’ve also been thinking for a while now about Stark’s successor. When I built Rimuru last year, I chose the name for three main reasons.

  1. Rimuru is rather overpowered and became a demon lord. 
    1. Centauri was built for a 5-year machine and nearly lasted the decade before her retirement.
    2. So, I was specing the replacement based on 10-years of service life and planning ahead for multiple refits.
  2. Aside from being largely new hardware: Rimuru’s key design factors are based on Centauri’s design processes.
    1. You could say that Centauri’s design was reincarnated as a modern PC.
  3. Obviously, I rather like That Time I Got Reincarnated as a Slime.

As such, I have a feeling that if Stark’s successor is from either of the laptop series that I envision, it seems that Shion would be a great host name for my next laptop. Because Shion is Rimuru’s first secretary, prone to solving problems with brute force, and tends to get him into trouble 😄.

In a somewhat similar convention, my iPhone SE 2020 was nicknamed Benimaru because I bought the red model and my transition from Android to iPhone, was not unlike the time Benimaru and the ogres showed up in Tempest all pissed off and ready for a fight. My devices are usually given a hostname based on whatever comes to mind relatively quickly in terms of the device’s personality. But once in a while, ideas pop up ahead of time.

Musings of an aging nerd

Having transitioned from “Gahh, no space!” to compact, so far the new desk is working out fairly well. If nothing else, it’s certainly nice to feel like I’ve got some desk space.

Because of the change up, I’ve been thinking of migrating Nerine’s charging point from my headboard to my desk, since it’s usually bedtime when I put my tablet on charge and that’s really the only time, I use my phone at home. My headboard’s been the charging station for ages, both due to convenience and the lack of desk space.

Actually, working off that metric and the dual desktop/laptop setup where usually my tablet is guarding my left flank anyway, I’m starting to think of my desk setup as the “Gateway station” where starships go in transient. Plus, the grey slab with technology sprouting out of it rather reminds me more of the space station in Aliens than any of the pocket-sized classes of Star Destroyer.

Evidence that Windows NT is in fact, the most annoying operating system when it comes to USB, or that me, USB, and Microsoft just don’t mix well += 1.

So, for the day I’ve been rather perturbed that about every ten minutes or so, Rimuru makes the USB enumeration sounds.

Running Device Manager in “Devices by connection” mode allows me to obtain a decent tree view of USB things. Fucking with cables like a mad man allows using the process of elimination to determine what the actual fuck device or port causes this.

Interesting to me, after process of elimination across all ports on my motherboard’s Intel controller and the twin ports on my ASMedia controller, I’ve figured out something interesting about my new Anker hub.

When connected to the ASMedia (directly or extension) the onboard network port shows up as Unknown USB Device (Device Descriptor Request Failed). Likewise, if you insert a memory card into either card slot, no driver letter appears, and it starts making USB enumeration sounds like a mother fucker. Looks like two ports on an NS1081 USB flash card controller judging by the device manager but doesn’t work. Connect something to the Gigabit port and it does not even light up past the hubs power up cycle. This is true even if nothing is connected to the hub’s USB ports, so that it’s a straight shot to the controller’s C port and as minimal a downstream power draw as physically possible (i.e., only the hub’s power LED, network port or sd port).

By contrast, connect the hub to my motherboard’s front USB-C port and instead of Unknown USB Device (Device Descriptor Request Failed) that entry becomes a typical AIX based USB Ethernet port. Didn’t try the card slots when connected to the Intel controller, but I imagine they would work in that configuration.

So, this boils down to when connected to the Intel controller the hub works just fine and when connected to the ASMedia controller, the bridge chips on the hub don’t work.

Also, by contrast if I swap in one of the HooToo USB-C hubs that are so ubiquitous on Amazon, it just works fine regardless of which USB controller it is connected to.

Yeah. Pretty much by down, I don’t really care which vendor is the problem child here. Fuck’em all.

BASB Categories of Intention and my digital brain

by

A while back, I came across Tiago Forte and his Building a Second Brain concept by way of a YouTuber channel that I follow. Watching a related playlist, Pick Your Digital Notes App: Step-by-Step Walkthrough also generated some interesting food for thought.

For the most part, I tend to apply a huge grain of salt or a tune out and keep walking relationship towards productivity, task, and time management systems. In my case, I was both interested in a little more detail in favor of deciding which side of my crap sifter that lands on and the rather lenghly list of notes apps referenced being cataloged by style.

In context, my long-term use of Evernote as my digital brain can be classified as the Librarian architype that Tiago mentions. I was quite amused, actually, how Evernote and that mentality went together in his playlist 😄.

But there’s another concept of BASB stuff I’ve seen that’s kind of curious to me at the higher level. Here’s an excerpt from one of my notes:

Categories of intention

  1. Tasks
    1. Actionable priorities separate from other stuff.
  2. Read/Watch Later
    1. Yeah, right.
  3. Projects
    1. Goals and deadline
    2. Longer term.
  4. Areas
    1. Important to spend and time on but no specific deadline.
  5. Resources
    1. Hang on to stuff.
    2. Collect knowledge, etc.
  6. Archives
Tiago Forte suggests these as notes. I envision them as notebook stacks, or notebooks that require a sea of tags.

Periodically, I try to re-evaluate and “Clean up” how information is stored, or “Filed away”. In thinking about how my notebooks have become laid out, I realized that most of my notebooks are largely one of these architypes categorized by some greater context to narrow the scope to what I am looking for during search.

One of the reasons I came to appreciate Evernote and, in many ways, modern applications in general, is a greater focus on data rather than files. This is why for example, as I’ve grown older the structure of my data has become less like an “Anally organized tree of fine-grained stuff” and more like a flat and wide breath of collections.

Where younger me might have viewed a structure like ~/Documents/Papers/General Knowledge Domain/Refined Knowledge Domain/Some Computer Science Study.ps” to be useful, contemporary me is just pissed off by the excessive nesting. I don’t want to spend my time organizing or finding, I want to spend my time using and storing information. So, by contrast, contemporary me would simply store such a PostScript file in my “Programming” notebook, attach tags for any relevant languages, and consider creating tags for the knowledge domain if and only if it’s likely key to being able to find the information again. That is to say, if I’m trying to narrow the hundreds of notes in my Programming notebook or searching across my entire Evernote, I might create a tag. In the area where I started to collect lots of digital information, tags were already quite the fad; one in which I have a relatively negative view towards after years of [ab]using tags.

Thus, presently my notebooks are relatively flat making it easy to glance and guess where stuff goes or should be found. Tags are for useful things only. No more debating which notebook is more specific — it’s either a high-level context, or it’s not a notebook! This is why for example, my Programming stack of “XYZ Programming” and “XYZ Software” notebooks were merged into Programming and Software notebooks and all the XYZ became tags or were simply unimportant. Part of why this works really well, is that computers have come a fair way past the old ‘find where | grep pattern‘ way of searching for data, but we still think in those terms whatever our tools for finding and grepping hae become.

My notebooks like Programming, Games, Hardware, Formats & Notations, Mathematics & Science, Linguistics, Food, Photography; are all notebooks in the domain of “Resources”, in terms of the above categories of intention. Whereas notebooks like Clipped Articles and Image Scrapbook would be considered Archives and notebooks such as Travel and Financial, would-be areas. Since I store a whole lot of stuff in Evernote, it really is like a library of resources and areas of focus, as well as other intentions.

I kind of like this notion of categories of intention. I may have to give it some thought both into my next great data cleanup and the relationship between tools that I utilize.

So far, my evil desk replacement plan has gone relatively well.

The riser that came with my new desk places the monitor too high for my tastes, and was kind of edge to edge. To compensate, I’ve replaced it with a decent monitor arm. In general: I tend to prefer my monitors lower when they’re larger / further away and high up there when they’re smaller / closer. My goal was to open room under neath for a laptop to be docked not change the monitor positioning.

On the flip side, my LG was pretty darn painless to replace its integrated stand with the arm. Using the arm also gives me better cable management and unlike the un-adjustable one my monitor came with; I could always add binder clips to it. Hehe.

Speaking of binder clips: since I had to rewire all the things, I added a pair to the back of my desk. One to the left to keep the monitor’s power brick from moving around and one to the right to retain the incoming Ethernet cable. I also fed my mouse and probably speaker data cables through it before routing accordingly.

To facilitate fast swapping between Rimuru and a laptop, I got myself a fancy USB-C hub. The USB-A hub affixed to monitor via velcro is now connected to one of its USB-A ports and my speaker is in its USB-C data port. Mouse, web camera, and Xbox adapter are in the USB-A hub on the monitor. Pretty much fetch an HDMI cable and network cable out of the closet and it’s a one cable swap to my work MBP, and a second cable for its charger. 

Because the hub’s cable can’t reach Rimuru’s 10 Gbit/s USB-C card and the 5 Gbit/s hub on the monitor was barely reaching one of Rimuru’s motherboard USB-A ports, the solution was a 10 Gbit/s USB-C extension cable running from his expansion card to the hub. That extension cable is retained by the same binder clip as the monitor’s power supply, so it won’t fall off between the narrow gap between desk and wall when swapping cables. ‘Cuz I know how that goes ;).

To facilitate this “All the things follow one cable” plan creates a bottle neck but considering that this bottle neck is a 10 Gbit/s, I don’t really mind. Most of my USB-A peripherals have limited power and data requirements. We’re talking about whether the 1080p web cam or the simple speakers draw more juice. Not trying to power a spinning hard drive and a desk lamp.

An added benefit of this novel approach is I’ve worked around an annoying problem.

Back when my first USB floppy drive went bork-bork, I had a spell where some of Rimuru’s USB-A ports seemed dead, then went back to working. In the months (~year) since then most of his ports behave in a way that makes me believe that most of the fuses are blown. As a consequence, peripherals have generally been moved to the USB-A hub on the monitor and it connected to one of the still good ports on the motherboard’s I/O panel.

Given that whatever the warranty status and pain in the assery of that might be, it’s probably a good thing my Real Focus on connectivity has been USB-C stuff, it’s probably a good thing that I bought that 10 Gbit/s expansion card for two more C ports. Considering the fuses are probably under the big ass heat sinkage and tiny as !@#$ to desoldier and replace, I’m going with definitely was a good plan to buy that expansion card.

Moving things to my one cable swap all the equipment plan kind of removes this problem. But to cope with it, I’m thinking of two more changes. Another hub on the back of the monitor that keeps the mouse/camera from sticking out the side, and a 5 Gbit/s expansion card to put some A ports where my motherboard’s PCI-E x1 slot is available. Since 10 Gbit/s requires an x4 slot, that’s already consumed by my USB-C expansion card.

Ahh, the joy of computers. Fuck them all.

Desk Plans

by

For the first time in quite a few years, I’m planning on a different desk setup at home. Actually, for the first time in about 16 years, I’m buying a new desk as part of the plan.

The small desk that I use has been slighted modified to suit my preference for keyboard on slab over its slide out keyboard tray. But otherwise, it’s about the same desk my mom bought about 20 years ago when we got a Pentium 4. Making the migration away from keyboard trays, and frankly having held up much better, is why it replaced my desk that I bought about 16 years ago when I got my own personal computer.

Here’s what I’m envisioning:

  1. A slab style desk about 40″ wide.
  2. Monitor riser to hold the big ass monitor.
  3. Laptop docked under the riser.
  4. Speakers to either side.
  5. Some means of swapping between tower and laptop.
For the desk part of this equation, I’m looking at this gaming desk. It’s close enough in dimensions to my mom’s old desk that I don’t think Corky will notice it encourching on his beloved bedside corner unless the cupholder falls off and hits him in the snoop or I spill a drink on his head. The included riser should be just enough to handle my monitor’s stand, and I could probably go with one of those arms if that doesn’t work out.
This should allow sliding my development Latitude or my work MacBook Pro under the riser, and in theory, maybe I can get away from the annoyance of the monitor leg being under my mouse pad 😂.
Having a slab of comparable dimension should maintain the benefit of having the room to the side for my laptop / phone / whatever the crap I’m working on but put it at the same height as my desk instead of being a “Lowered” shelf the size of a PC shelf. The lack of a place to stow my PC other than on the slab means that Rimuru will probably end up on a little rolly stand of his own, or that I’ll duct tape some cardboard together to make one.
The part that I haven’t quite figured out is device swapping.
On the back of my monitor there are strips of Velcro affixing a Gigabit switch and a USB hub. On the top is my webcam and behind are my speakers jacked into one of the dual USB-C 10 GBit/s ports on Rimuru’s expansion card.
Stack has a Dell docking station that solves most problems of interfacing if it fits but won’t be able to share much. Whether I replace it with a shiny XPS or a Mac someday, my next laptop is going to have USB-C ports much as this was a design requirement when I built Rimuru! Since most of my gear is either Bluetooth (keyboard, headphones) or USB-A (mouse, webcam, USB-A hub, Xbox controller adapter) it would be relatively easy to swap from desktop to laptop as desired by using a USB-C hub because the only Bluetooth device switching around is one with multiple device pairings. The sticky one is that my speakers require a USB-C for their data connection to actually work. The only solution I’ve been able to figure on so far, is one of the few hubs readily available that has both USB-A and USB-C ports. I figure that most connections of interest can be routed to such a hub, along with display/network for the laptop. Personally, I would prefer something like the 4-port USB-A hub on my monitor but as a 4-port USB-C hub, but those are still harder to find as most vendors are C-to-A style hubs and most have short cable lengths. The alternative would be having to switch my speakers between USB-C input and Bluetooth mode, which isn’t totally convenient since they would still need Rimuru to be powered on, making USB the better deal for toggling between devices.
A tricky part of this is the cable length such a hub. That effectively means that cable swaps would require running a USB-C to C extension cable from Rimuru to the hub and swapping the hub between that extension cable and whatever Stark’s successor is. And probably hoping that the new desk or riser lets me put binder clips on the back for cable retention, to keep the cable for falling off, lol.
Well, at least that is my concept for right now.
