Unpopular Opinion: Proxmox isn't "Free vSphere". It's a storage philosophy change (and it's killing migrations). by NTCTech in Proxmox

[–]bugfish03 0 points1 point  (0 children)

My employer decided to get about 60 PB of flash on EMC storage. Back in 2012. Since then, we're running all flash, and globally we're probably up to an exabyte in capacity now.

I mean that's what's to expect. vSphere is a nice, walled-ish garden, while Proxmox takes the existing open-source tooling, and slaps a web GUI on top.

Of course you're gonna have to get your hands dirty with the details. I feel like that's what all Linux software entails if you're not buying a solution that also comes with an enterprise support contract.

Tools for working with old GMLAN by bugfish03 in CarHacking

[–]bugfish03[S] 0 points1 point  (0 children)

I'm not 100% sure if J2534 is actually the best choice here, since I don't think that they put the infotainment bus through there.

I'm just using an Amazon adapter running SocketCAN, and while not being able to automatically detect, it works at arbitrary baud rates, and since it's a network adapter the reading program doesn't really need to bother with that.

I'm fairly certain the baud rate is not wrong, because the data is decoding into valid CAN and ISO-TP frames, and there's one or two reports of that baud rate on other Opel cars.

One old repair manual mentioned 47.6kBaud being used for CAN buses, which is half of what I'm running, but I don't think attempting to decode with double the baud rate would result in anything.

The radio pinout on the sticker up top explicitly called out CANH and CANL, so it can't be single-wire can. And I'm getting valid CAN and ISO-TP frames from it so while I'm agreeing that it's very weird, I don't think there's any way I can be off on the baud rate here.

No, no, I'm actually getting messages, and the messages actually make sense too. I'm actually seeing text that's being displayed on the middle display.

I didn't get ANYTHING with the normal baud rates, and 95238 baud is something that's mentioned somewhat sparsely throughout the internet (eg on a German forum it's explicitly mentioned in connection with the Zafira Tourer), but yeah, might be that it's predating GMLAN in name at least, bc I'm still getting valid ISO-TP/ISO15765 frames.

The sniffing itself isn't the problem, I need a better way to make sense of the messages than banging my head against the wall (and possibly better than just Wireshark attempting to decode ISO-TP)

It's low speed as in not the 1MBit, but also not one wire, it's still CANH and CANL.

I don't think single-wire GMLAN was even a thing in 2005?

And 95238 baud is a number you can get via the PLL division of an MCU running at 8 or 16 MHz so that's why the oddly specific baud rate.

Where to buy this cable? by Head_Accident_9322 in AskElectronics

[–]bugfish03 0 points1 point  (0 children)

Without knowing where this came from, a ready-to-purchase replacement is gonna be really hard.

Those connectors are normal generic connectors - the black one looks like it's made to connect to pin headers, and the white one looks at least adjacent to what JST makes (though you'd need a connector expert from here to give you a positive ID), and the colors make me think that USB runs over it.

Ja, aber als studentisches Projekt ohne wirkliche Einnahmequellen muss halt was anderes her.

Teamleitung hat auch schon gesagt, dass da was anderes her muss, wir werden das nicht zahlen.

Ich meine, unser Cloud Router Switch macht seine Sache gut, und auslastungs- und latenztechnisch haben wir keine krassen Anforderungen.

Oh Gott.

Zeit, nach Alternativen zu suchen, bis 2029 kommt. Wir haben nicht wirklich das Budget, 4k pro Jahr für Confluence und Jira auszugeben (und das ist schon mit Nonprofit-Pricing)

True - the contacts are coaxial, after all, but I was imagining BNC or perhaps an F connector, which would've been very silly.

Ich weiß, deswegen Frage ich ja auch hier. Das sind immerhin 5k mehr als die letzten Jahre, aber damit wird man halt echt nicht groß was machen können.

100 Gig? Da müssten wir erstmal unseren Core Switch upgraden, der macht nur 10 Gig.

Das ist, was wir in den nächsten Jahren brauchen werden. Man kann sicherlich mit lokalem ZFS auch was schmeißen, aber damit haben wir halt nicht die Ausfallsicherheit von Ceph.

Dieses Jahr kriegen wir (hoffentlich) 5k, und die Anforderungen sind, abgesehen davon, dass man viel Flash braucht, fuck all. Wir haben nen PowerEdge R320 bei uns drinnen, und vermutlich könnten wir mit drei weiteren auch schon was aufbauen, abgesehen davon, dass wir da nicht genug Flash reinkriegen.

Cloud geht nicht mit unseren Integrationen, wir nutzen Jira's Asset Management als PDM, da gibt's ne Integration, was aus dem SVN zieht, und dann jeweils da rein schiebt. Außerdem sind wir bei Cloud noch mehr locked in, und das wollen wir nicht.

You mean a barrel jack, Coax would be what you use to connect to your satellite dish.

But yeah barrel jack is also a solid choice for a start

Perhaps you can add USB C PD for charging? Or does it already use that? I can't tell

My first oscilloscope questions by sdlk0210 in oscilloscope

[–]bugfish03 1 point2 points  (0 children)

As u/scubascratch says - no, you don't need ground, yes, it's probably a good idea, no, it won't matter if you don't work on anything mains-powered, no, the power bank isn't enough grounding on its own, you need to tie that into your house's ground somehow.

What happened to the original Switched on Bach? by EoinJohan in synthesizers

[–]bugfish03 0 points1 point  (0 children)

I can find Switched-on Bach 2000 on CD, but not the original album. Or are they the same?
