Yikessss the 1980's US government quarantining a huge percentage of the gay community... That ain't it. HIV is not easy to communicate to other people. Education and PrEP have reduced the problem immensely.

It can't be "rolled into" the gcode though. Gcode is sadly extremely limited, and while you could build some pretty complex extensions, there is no reason to avoid switching to a (cheaper) more powerful microcontroller to avo

No, on most CNC machines the controller actually handles much of the motion planning. The slicer will generate a command that says go from point (x1, y1, z1) to point (x2, y2, z2) with speed f, but it doesn't say anything about acceler

Why do you think I have imperial interests? Is it because you think everyone does? If everyone does, does that mean you do? In that case, what is the answer? Do we just wait around until China somehow out-imperials the US and not be critica

> Sure, but now they are a small company that has to maintain two separate codebases. Even big companies like Google can't keep their Android and iOS apps at feature parity, so something has to give and it's the early adopters

Damn I never thought I would run into a tankie on HN. Neat. Your criticism isn't totally invalid (if unreadable), but not everything is reducible to class. Stop reading weird blogs about how socialist China is and get outside and do so

Additionally, we don't need to speculate, they explained their reasoning in the article: > Why did we decide to switch to a 32-bit board? Surprisingly, raw performance is not the main reason. We can now write cleaner and more abstra

I've literally never firmware updated my Prusa and it works totally fine. This is a bit of a bizarre nitpick. Hell, you can build your own firmware if you really care that much.

There are a ton of online services that allow you to order 3d printed parts from your own designs. The quality will likely be much higher than what you can print at home as well.

No everyone needs a 3d printer for sure. A big part of what stopped the idea that 3d printing would be this magical revolution is that designing plastic parts is actually fairly hard. I don't use my 3d printer to 'fix' things

These threads are always a strange and uncomfortable bridge between valid criticism (many products made in China are cheap and break easily, the Chinese government uncomfortably authoritarian) and actual racism ("the Chinese" only

It's not _just_ a different point of view though. It's Turkish propaganda and even includes a "hordes of others" reference which comes from an ultra-nationalist viewpoint that is incompatible with modern values. Furtherm

I would much rather have a society of equitable Marxist-Leninists (which they are not) than authoritarian far-right Turkey. At least their values would be in line with mine, regardless of their political ideology. It's pathetic that yo

I have two comparisons in mind. I've used a corded, $500 Dyson, and it's really awful. So many little, annoying design decisions and just an overall lack of power for a corded vacuum. For the cordless ones, I've used the V7 (

It's great that they've improved, but I'm still confused about the hype. The best Dysons I've used are worse than my old, $400 Miele. They may be competitive now, but it took them 10 revisions to get to a point other man

Not everyone is aware of the extent and power of institutional oppression in America, and we can think of more than one thing at once. Realizing the double-standard doesn't prevent me from being upset at the institutional powers that g

Those were rhetorical questions. Like you said, through our system of democracy, we _allow_ the markets to exist in a particular form. We _allow_ the government to administer force to protect the peoples' ownership of private property.

The author's solution may still help somewhat, but yes, they are almost certainly wrong. This transistor really just isn't being driven properly, because it really shouldn't generate heat in this application. It could a whole

Yeah this looks like an SOA violation to me based on the hole. Usually you would turn a FET like that on slowly to avoid high inrush current into the downstream circuit, but ~10ms seems a bit silly. That would also explain why this escaped

by dfasdfasd 7y ago
It's not cooling. A switching transistor in that application shouldn't make too much heat. We don't know the voltage on the rail, so we can't say exactly what it is, but the likely candidates are an SOA violation because
