OctoPrint 5 years ago

It might have to do with the USB buffer on the Ender. If the buffer is too small (e.g. 4 gcode commands or so) then when the buffer is filled with commands that execute very quickly, its possible for the printer to empty the buffer before new commands come down the pipeline from Octoprint. This causes the printer to stop the printhead sharply, which can cause quality issues on prints, or maybe even print failure if the sudden stop causes the print to detach from the bed.

[You can fix this if you're using Marlin](https://www.reddit.com/r/ender3/comments/btjk22/octoprint_is...), since Marlin allows you to configure the buffer size. Generally more buffer is better, but do be aware that increasing the buffer size will cause the printer to be less responsive to the "stop print" command on octoprint (since the printer will continue executing the commands that have been buffered).

Just to clarify, that means that I would need to 1.) purchase some packs of Kong, which are unloaded, and then 2.) participate in a lockdrop to gain the tokens with which to load the Kong? Seems fine and dandy wrt the acquisition of bills, but how will adoption by vendors happen?

Question: since bills can be either loaded or unloaded (either because they haven't been put in circulation yet, or because they're counterfeit), doesn't that mean that e.g. a vendor taking my Kong who has no trust in me would have to individually check each bill via NFC or i2c to make sure that the contract backing the bill is valid (and the correct amount, etc.)? And that I would have to do the same for all the bills I get back as change? As a completely trustless transaction, this seems like it could be entirely too slow for most applications, without some kind of device to quickly verify multiple bills.

Is it riffing off ranch dressing? I've heard that ranch is associated with the US, outside of the US.

Edit: looks like "american sauce" can refer to a multitude of things. Typically it seems to either be some kind of ranch or thousand island.[1] Both of which are separate from "Sauce Americaine", from French cuisine.[2]

2nd edit: If the OP is talking specifically about Heinz brand "American Sauce", apparently the closest match in American cuisine is either thousand island or big mac sauce/"secret sauce" used on burgers (which is based on thousand island). It is pretty American, come to think of it.

When I first read your comment, I thought that there was no way that solar panels could be heavy enough to affect your mileage. So I did some quick calculations.

Estimates of solar panel weight I found say that solar panels tend to weigh 2-4 lb per sqft.[1] Note that estimate is for roof-mounted solar panels, but if anything, car-based solar panels should be lighter.

A Prius has dimensions of 180"x69".[2] The sqft of the solar panels will be less than that, since the panels don't cover the windshield, and they don't go all the way to the edge of the hood, etc. That's 86.25 sqft, so that puts an upper bound on the weight of the solar panels at 345 lb. If we assume the lighter end of the scale for solar panel weight, that becomes 172.5 lb. That's 6-11% of the curb weight of a Prius. That's pretty substantial! For reference, a 50 lb spare tire kit can reduce fuel economy (and presumably mileage, for EVs) by 1%.[3]

Although that does imply that you're breaking even if the solar panels can increase your range by ~5%, not accounting for the weight. If you live somewhere like Arizona, that might work out. If you live in Seattle, maybe not.

That's fine, because when something breaks the day after you've pushed, it's Friday and everyone's in the office. People are still going to rush the deadline, but putting the deadline earlier means you have time to deal with stuff that breaks after the deadline.

Who Owns Huawei? 7 years ago

Never heard of it, never thought about it, not sure why proving/disproving this is in the author's interest.

It is in Huawei's interest to not be labelled as a state-owned or state-controlled actor. The perception of being controlled by the Chinese state is precisely why many western countries are leaning away from purchasing Huawei networking equipment for their up and coming 5G networks, and also (at least in the case of the US) advising against, and then banning, consumer electronics made by Huawei. Huawei has been trying to convince the public that it is in fact employee owned and therefore not controlled by the Chinese state by touting its "employee virtual ownership program", and the purpose of this paper appears to be to dispel that notion.

From the original 2015 article about the hack:

"Miller and Valasek’s full arsenal includes functions that at lower speeds fully kill the engine, abruptly engage the brakes, or disable them altogether. The most disturbing maneuver came when they cut the Jeep's brakes, leaving me frantically pumping the pedal as the 2-ton SUV slid uncontrollably into a ditch. The researchers say they're working on perfecting their steering control—for now they can only hijack the wheel when the Jeep is in reverse. Their hack enables surveillance too: They can track a targeted Jeep's GPS coordinates, measure its speed, and even drop pins on a map to trace its route."[1]

The wheel control only working in reverse kind of makes sense. They're probably using some kind of self-park feature to control the wheel, and some engineer (sensibly) put in some kind of interlock to prevent the wheel from moving on its own when travelling at speed.

The wording of the article implies that these particular attacks only work when the car is travelling at low speed, but earlier in the article they did mention that they could (and did!) throw the transmission into neutral while the Jeep was driving on the highway. The driver was unable to recover without turning the car off and back on again.

In a followup a year later, they showed that they were able to do these attacks at any speed, including turning the steering wheel.[2]

The lacing isn't plastic, it's (as the article mentions) typically waxed linen or some other type of fiber/rope. Zip ties have to be made of a more solid material like plastic, since you need to mold in all those tiny teeth that cause the zip tie to ratchet closed. It's neat that a lot of these plastics are apparently tasty for rodents and other pests to eat though; I wonder if you could add a bitterant to combat this. But zipties will still have other issues caused by the plastic material: brittleness from UV exposure, and cracks due to freeze/thaw cycles and thermal expansion. There's other (non-plastic) alternatives to cable ties though, for example metal hose clamps. Although that might be too harsh on the cables, not to mention being conductive. It seems lacing is by far the gentlest option on the cables, and longer lasting than zip ties, at the cost of requiring more time to set up correctly.

It can at least bias your priors ahead of time. When you (as a human) are using Waze or Google maps and you see a speed trap ahead of you, or a traffic jam, or construction or whatever, obviously you can't blindly trust that. But you can slow down and prepare, and if and when that occurrence comes to pass, you're better prepared to deal with it.

Gravity is not uniform everywhere on earth, because the Earth's density is not uniform. (This is ignoring the other consideration that the earth is not spherical. Because the Earth bulges at the equator, gravity is also weaker towards the equator and stronger at the poles.) Satellites[1] or humans on the ground can track variance in the gravity field. This is normally done to find underground deposits of valuable minerals or metals, as may be slightly denser or less dense than the equivalent volume of earth/stone.[2] I think OP was wondering if the presence of the impact site would show up on such a survey of Earth's gravity field.

Lyft Files S-1 7 years ago

There's nothing preventing drivers from driving for multiple apps, though. Most Lyft/Uber drivers I see these days have both stickers in their windshield.

For the first year or so of my job, I actually used a chromebook to SSH into my work desktop to do work remotely. (I'm a Googler and they were pushing new hires to try the chromebook over the more traditional macbook/thinkpad.) It was fantastic! The chromebook itself basically does nothing so the battery life is absurd, 10-12 hours easy. The chromebook starts up really fast because, again, the machine itself does almost nothing. It's certainly nothing like the portability or the stupid long battery life of a TRS-80, but it's a step in that direction.

I later swapped to a macbook because the chromebook kept dying. In that 1 year period, I went through 3 chromebooks, which all ran into some kind of memory corruption or thermally-induced restart issue. It was the HP 13 inch chromebook, which I will be avoiding like the plague in the future. I still really like the chromebook battery life and the general "very lightweight portal to the internet" kind of paradigm, though.

Wine is probably the most extreme example as there's a heavy push to equate fancy (expensive) with tasty but very often the 2 don't correlate.

I would say the poster you're replying to would agree. And while it's true that price is largely unrelated to quality for wine, in blind taste tests, professional sommeliers performing a blind taste test do significantly better than chance when it comes to determining grape variety and country of provenance.[1] Which is to say that there are subtle differences of flavor from wine to wine that are detectable. But again, this is far from saying that expensive wines are better than cheap wines.

Other commenters have posted good links, but in very large fish such as tuna, you can see macroscopic effects of this muscle degradation.[1] It's not so much an effect of the "stress hormones" in the body as just the fish overexerting itself as it flounders about in the boat, while also asphyxiating. And you're right about the spinal cord still being able to send signals to the body without the brain, which is why the full procedure is not only to destroy the brain but also the spinal cord, by inserting a rod or monofilament down the length of the spine.

I've had the same problem any time I get glasses that don't have nose pads (i.e. the frame just sticks out a bit to touch the nose, rather than there being two plastic pads attached to the frame). But I found that you can buy stick-on silicone nose pads from Amazon, and these work perfectly for me. They're these little D shaped silicone pads that are sticky on one side, and maybe 1.5mm thick. You stick them onto your glasses frame and 1.) they help the frame grip your nose bridge, because they're silicone and therefore grippy, and 2.) they space the glasses a little further from your face. You have to replace them every month or two since the adhesive gives out, but they're pretty cheap and definitely worth the hassle.

Some of the post's salad examples (spaghetti, poutine) could be interpreted as starch surrounded by non-starch. Thus I believe the rule would still consider turkey with stuffing to be a salad.

Also echoing mabbo, I did a sleep study in the comfort of my own home about a year ago. I'm told it's not as precise as a "proper" sleep study in a lab since the instrumentation isn't as precise, but it was basically just a band that I strapped to my head before bedtime. No drugs, no technicians. Just some accelerometers and a microphone to hear what your snoring sounds like. And that was enough for my doctor to diagnose me with mild sleep apnea and give me an oral appliance. Basically it just forces my jaw forward while I'm sleeping, which keeps my airway open. Never tried CPAP but I'm told that the oral appliance is much less intrusive.

You have to set your particular console as your PSN account's "primary" console. When a console is set as your primary console, any other accounts on that console can use software that you have bought using your PSN account. However, I think only one account can have a particular console set as their "primary" console at a time, so if your PS4 is your account's primary console, then it cannot be your wife's account's primary console, meaning if she buys software, your account cannot access it.

Which other true wireless earbuds have you tried? I bought some Jabra Elite Active 65t's and I've been very happy with them. I don't have the Airpods so I can't do a direct comparison, but from what I've read, the 65t has a bit less battery life in the case, but also has an actual noise isolating design. They're about the same size as the Airpods (and they don't have the stem, so depending on how you count they might be smaller), still have a 5 hour listen time without charging from the case, and seem to have a higher audio quality. I've heard similar things about the Samsung IconX as well. I would consider at least these two products as in the same class as the airpods: similar functionality at a similar price ($130-170). But I'm really interested in your perspective as someone who's used both the Airpods and other wireless earbuds.

Obviously, growing every quarter significantly is not sustainable. But growing profits every quarter is how stock price goes up, right? Assuming you don't pay dividends on your stock, if you don't grow profits every quarter then your stock price doesn't go up, and the shareholders (via the board of directors) will sack the CEO. The whole incentive structure for corporations seems to cause the short term thinking that you see in large companies. Can you keep the shareholders placated by paying dividends instead of growing stock value via growing profit?

The American car market as a whole are almost entirely automatic due to overall consumer preferences. However, there is also a minority of enthusiast drivers who greatly prefer manuals and are very vocal as such. Cars that are marketed more towards the enthusiast end of the market are those that you'll find stick shifts in more often, e.g. Miatas, Porsches, Corvettes, etc. These days though, even the enthusiast cars are selling many more automatics than manuals.

Not OP but I read the Slate Star Codex article, and buried about halfway down was:

"These don’t “cure” the condition permanently; you have to keep doing them every day, or your circadian rhythm will snap back to its natural pattern."

So it looks like you have to take the melatonin on a continuous basis.
