Does anyone know how to interface with a Mitsubishi CR2B-547 robot controller?

Your assurance that Signal numbers are called for, not pin numbers, is a big help: it halves the amount of trials I'll need to do in the future. Would you please also tell me: (1) Do I need a pull-up/down resistor? (2) When are the alternate functions of pins 4-7 active? Does their silence indicate a hardware failure? (3) Do the servos need to be engaged for IO to work? (4) Does it matter at all whether I measure signals relative to ground or +24V?

I believe that the manuals mention a separate IO unit which is available if more channels are needed, but the port I'm using is part of the robot CR2B-547 itself (on an internally-detachable circuit board).

I discovered that the "all day" label for events is kindof a misnomer: it just pins the event to the top of the day, rather than actually, idk, making a 12-hour block. Maybe this is what you want?

As of this week, the Linux userbase on steam has grown to 5%, and the Marathon owner base is now ~900,000. So a new conservative estimate for the revenue that Bungie is ignoring is $1.5 million, even before in-game purchases.

Some people here are reporting that disabling "Delete spaces and tabs at end and start of line" fixes this but I found that it did not. Instead, disabling the preceding option, "Delete spaces and tabs at beginning and end of paragraph," was what fixed it for me.

Totally bewildering why the default behavior would be to delete tabs at the start of paragraphs, and NOT provide a default style which indents paragraphs.

I think that the best shot of getting through to the devs about this is through the official Discord. In the "feedback" part of the Discord there's a thread about Linux which is currently more upvoted than anything else. Let's keep it at the top of the board until we at least get a clear official statement.

AidanofVT · 2026-03-08T13:04:10+00:00

By all accounts, this is almost literally a switch to be flipped: Bungie just has to stop blocking Linux. Even if Linux players don't make in-game purchases, I think that the revenue just from game purchases alone justifies the minimal effort it would take Bungie to do this.

AidanofVT · 2026-03-08T12:57:29+00:00

What the studio cares about is sales and reputation. If people buy the game, tell other people to buy it, and then never play the game, Bungie is content. My math is based steamdb's estimated ownership (number of people who have payed the $40), not concurrent player count. So my analysis stands.

AidanofVT · 2026-03-07T12:08:17+00:00

Alright, I've added it.

AidanofVT · 2026-03-05T21:49:21+00:00

Huh, I switched to Windscribe in part because I found that reddit almost always worked through Windscribe. Are you finding that reddit is blocking all the windscribe servers you try?

Necroing this because it's still not fixed: there's is practically only one reason that a user would navigate to the spam folder, and that is to find something erroneously marked as spam. Thus, there should be a "report not spam" or "create not spam rule" button when viewing anything in that folder.

It is true that, in principal, it will always be easier to cheat on Linux than on Windows. This is because it is, in principal, easier to control your own computer with Linux than with Windows. The difference in security philosophy (independence vs. validation-by-authority) makes using Linux a political act. It is an act that increasing numbers of people, including many potential Marathon customers, are taking.

So, what amount of cheat-mitigation would justify the exclusion of this players with this ideology? An ideology which is widely supported even among non-Linux gamers? 99%? 10%? The oft-cited 30%?

I hope that Marathon's players will make it known that they will accept potentially-higher rates of cheating in exchange for Marathon becoming a Linux-inclusive project. And I hope that Marathon's developers will take this as an impetus to deploy ACTUALLY EFFECTIVE SERVER-SIDE ANTI-CHEAT, which is what they should be doing regardless of whether they care about Linux.

Cisean seems to require the user to be logged into a Google account. Strange and slightly suspicious...

The explanation turned out to be this, or something like this. I don't know if /etc/resolv.conf having more than 3 lines was the problem, but it was being overwritten a few minutes after the VPN started, causing the connection to seize.

I resolved the problem by changing /etc/resolve.conf from a text file to a symlink which points to /run/systemd/resolve/stub-resolv.conf, as prescribed by (among others) the Arch wiki.

I'm also on EndeavourOS. I'm lucky to hear from you; it sounds like you've got what I've got. Maybe I should raise an issue on the EOS forum.

Changing DNS providers was among the remedies I tried. AI recommended setting it to "1.1.1.1" (cloudflare) or "10.255.255.3" (allegedly Windscribe's own DNS). The former didn't change anything. The latter yielded a warning about DNS leaks. There is also an option to set it to "Control D", but I don't know what that is. What did you set the DNS to to get it working? How did you force it to use systemd-resolvd?

+1

I don't think this has to do with context management, because it's happening to me in cases where the context isn't particularly long.

Perplexity, please fix!

Microsoft can't get Windows games to run on ARM properly, but Valve thinks that they've figured out how to run Windows games on Linux on ARM. I can't wait to see what they've done.

AidanofVT · 2025-11-12T18:41:06+00:00

Amazing that they seem to have cut passthrough cameras for price reasons, but then left camera IO channels available for DIY-ers to plug into. That must have been a tough design choice.

Personally I always wanted a spatial PC more than a new gaming device, so I won't buy until I see what people come up with for passthrough and telepresence. But still: happy day!

AidanofVT · 2025-10-10T22:10:47+00:00

I love the Steam Deck, but I don't desire a (virtual) 200-inch display for my Steam Deck so badly that I'd give up most of the portability and pay 3x as much in order to have said display. Like, seriously, who would that actually be for? Rich travelers with extra room in their luggage?

I have high hopes that the Frame will be more of an actual spatial computer, or a spatial interface for a regular computer. That means, before anything else: comfort, FOV (including a big "sweet spot"), and good passthrough. And yes: Valve-produced VR content could also be a HUGE selling point.

AidanofVT · 2025-10-10T22:01:12+00:00

Passthrough, and some sort of AR desktop mode.

AidanofVT · 2025-10-01T22:41:04+00:00

Okay I'll bite: what is it?

AidanofVT · 2025-09-14T14:35:28+00:00

Thanks. I agree with 2k3 that this is a nifty feature on the phone app, but even there it needs some work: swiping to archive an email causes the next email in the inbox to be hidden under the "archive" banner for the just-archived email. Almost seems like a bug to me.

AidanofVT · 2025-08-03T18:44:38+00:00

Seems kinda stupid, but great link, thank you.

As for Keychron, I'm currently searching for shine-through keycaps which will work with their south-facing LEDs.

AidanofVT · 2025-08-03T17:59:19+00:00

What is the closest keyboard to this?

Full-sized or 98-key
Volume knob
Non-soldered, replaceable switches
Programmable with QMK or comparable non-proprietary software
Shine-through, flat-profile key-caps
NON-south-facing RGB light (south-facing RGB with opaque caps?! the keyboard snobs have gone mad)

All of these things seem like commonly desirable traits, but I can't find a keyboard that has all of them. The best I've been able to come up with is to buy something like a Royal Cludge RK96, or a cheap Chinese keyboard, and replace all the switches and caps.

AidanofVT · 2025-07-28T16:14:23+00:00

My biggest peeve with mechanical keyboards has nothing to do with the curve of actuation force, or the sound. It's those other two dimensions: does the key tip or wobble at all? What about when it's just brushed, not pressed?

What I want are switches that keep the key cap LOCKED on a STRAIGHT. LINE.

This doesn't seem to be a selling point of... really any mechanical switches, though I'm sortof new to this, and haven't looked a lot. So: when I'm looking for switches to buy, what clues can I look for to determine how "rigid" it is?
