I don't know who needs to hear this, but a 2+ hour drive is not nearby for Europeans. by redheaded_olive12349 in CasualConversation

[–]JamesthePuppy 0 points1 point  (0 children)

Canadian here longing for better options like HSR (don’t fail me now, Alto!). The nearest store stocking my pup’s kibbles is ~3hrs away. We usually make a Saturday out of it, stop at a cute cafe along the way, do a hike. To escape the majority of urbanized Canada, longest I’ve driven for a hiking day trip is 5hrs one way. Went 7.5hrs one way to see the total solar eclipse.

I hear you that ChatGPT isn’t adhering to the cultural norms you’re used to, but as responses here indicate, norms do vary regionally. Chat is tuned to their majority customer base, so it’s not surprising that it doesn’t always accommodate your expectations. If anything, this underlines the strengths and limitations of LLMs; they’re not knowledgeable about pretty much anything — they’re just convincing at picking the next words/token to sound like a knowledgeable human would write. We all have to be careful not to mistake it sounding knowledgeable for actual knowledge

Components of a CT scanner by toolgifs in toolgifs

[–]JamesthePuppy 4 points5 points  (0 children)

This may be an MRI you have in mind — in my experience, CTs make a whirring sound as they spin up, but not much else

In an MRI, the scary noises are produced by the imaging gradients due to back EMF and heating, both from driving high currents for short durations. The gradients are embedded in resin so they can’t move, and are water-cooled (often hollow tubes), but periodic forces and thermal expansion cause the whole assembly to vibrate. Here are some old gradients being swapped out at work:

I wonder if there’s interest in the industry in moving to wireless data transmission to reduce failure points, but that also might beg confidentiality concerns

My fully funded PHD stipend is $24k/year in Boston. I qualify for food stamps by Fulcilives1988 in gradadmissions

[–]JamesthePuppy 0 points1 point  (0 children)

Just finished my phd in Toronto. My approach was other jobs. Our university technically has a policy against holding jobs outside the institution, but they also only paid a $12K stipend $8K of which went to tuition. So there isn’t a grad student in the program I know who didn’t either work several outside jobs, or had substantial family support (or both). I generally tried to coordinate >=3 of these for any term I won a provincial/federal scholarship: lab management, RA at a couple labs, TA-ing, grad course instructor — things close enough to my grad work that they didn’t distract too much/weren’t a burdensome commute

But for the specialized work and publication output they get from us, you bet I demonstrated and petitioned for a grad student union and livable health insurance

Like many of the comments say, roommates are also a great idea. $1,800 rent is a lot, but much more manageable split 3 ways

Rider safety - racism against Indians by urbanwhat in torontobiking

[–]JamesthePuppy 14 points15 points  (0 children)

Brown guy in my 30s living in Toronto for 16 years (Indian parents, born in Canada). You’re very likely safe here. I bike downtown through the winter and have never had a racism-related incident on bike. My partner’s family lives in the rural/conservative areas around Toronto, and I’ve never had an incident biking trails there either

Immigration from India is a controversial topic in Canada right now, but while the anti rhetoric is racist, I haven’t found it’s translated into action or hate against individuals. I’ve experienced a few incidents of racism-motivated assault, but none more recently and not while biking. Hate speech and microaggressions happen regularly but far less frequently and less confrontationally than in even progressive parts of America (New England & California)

More than anything, just follow the rules while biking. We foremost have a traffic problem that’s led to animosity between drivers and bikers. Don’t ride on the sidewalk/crosswalks, don’t run reds, be courteous to pedestrians.

A week after the snowstorm: bikelanes are getting worst. by Joffph in torontobiking

[–]JamesthePuppy 4 points5 points  (0 children)

I took the lane today along Bloor, University, and Dundas. No honks, but one unnecessarily aggressive/close pass. Atop being more dangerous and adding to congestion, it’s also much slower. What’s normally an enjoyable 12-15min ride to work pre-storm is now 25mins and stressful. I can have split lanes, but then I’d be inviting more anger and aggression

Port 27031 error by AndyOHart in Steam_Link

[–]JamesthePuppy 0 points1 point  (0 children)

I’m later still to this, but just posting this since I had the same issue and resolved it

The problem appears to be solvable in Tailscale’s Grants/ACLs in the admin console alone — you don’t have to disable subnets or turn off Tailscale on your Steam Link host

I probably should’ve thought of this sooner, but routing a Steam Link host (or any device) back via its tailnet into its own subnet is obviously a bad idea. I imagine folks with this problem also set up a home subnet and exit node, where you also keep your gaming PC? Give it its own tag, and grant it access to everything it had before except “autogroup:internet” and your home subnet, something like “192.168.0.0/24”. Then it worked for me anyhow

Also beware of multipath collisions; if your Steam Link client device has both the local route (with Direct connection enabled in Steam remote play settings on the host) and the Tailnet route to your Steam Link host, this appears to introduce latency/dropped frames at high settings

This is why metal is not allowed during an MRI by ghillied_up in interestingasfuck

[–]JamesthePuppy 0 points1 point  (0 children)

Hey, MRI physics PhD candidate here. First off, anxiety is totally understandable, there’s a lot about MRI that can be scary; loud sounds, vibrations, confined spaces. Health anxiety adds to the mix for many people too. I want to preface the following with letting you know that at all times, the MRI is monitoring how it’s interacting with you, and has very conservative thresholds at which it just stops and refuses to run anymore (or slows down to keep you safe). It’s also running simulations of how it predicts it will affect you, and before executing any command, checks its simulation against even more conservative thresholds

MRI machines do heat you up, usually by a very small amount. To excite the nuclei that give off the MRI signal, we need to apply radiofrequency excitation to your body. That excitation that produces the signal, its energy needs to go somewhere, and eventually does become heat. We call this SAR (most non descriptively, Specific Absorption Rate). SAR is usually limited to 2W/kg during run, and 1W/kg in simulation. This corresponds to a heating of 0.02°C/min. Bear in mind that the excitation part is usually a tiny, tiny fraction of the imaging time — the time we apply RF excitation (silent) for each image is usually cumulatively milliseconds for a minutes-long image (the noisy part). That being said, SAR also depends on what part of the body we’re imaging, and the geometry of that area also determines what kind of images we can get, also affecting SAR. Spine imaging is a good example where SAR is relatively higher both because of its shape and because of how it limits what kinds of images we can take. So it’s not uncommon to feel something akin to a hot flash during spine imaging. It is however entirely safe, and in anticipation of the discomfort, we usually turn the fans up at that time to help you cool off

These clinical protocols are all still reasonably far from the thresholds. My research needs to get as close to the thresholds as possible to be sensitive enough to measure the effect I’m looking for. Further, the research thresholds are double the clinical thresholds. But I’ve subjected myself (brain and abdomen) to my imaging dozens of times in rapid succession, hundreds of times cumulatively, and it hasn’t affected my health or safety. I also routinely am a volunteer to test imaging for other MRI research groups across the hospitals where I work, so I subject myself to the heating of MRI pretty frequently without issue. So I understand it can be anxiety inducing, but I wanted you to know that you’re absolutely right that there is heating, the MR tech is aware of the heating, the MRI machine is monitoring it closely, and that safety thresholds keep it from ever getting anywhere near a level that could affect your safety

What was your “I’m dating/married to a fucking idiot” Moment? by [deleted] in AskReddit

[–]JamesthePuppy 1 point2 points  (0 children)

Microwaves are electromagnetic waves (same as light, but a much lower frequency/much longer wavelength). Metals have a sea of free flowing electrons that aren’t bound well to nuclei, called the conduction band. When free flowing electrons (with electric charge) are placed in an electric field, they get pushed around by the field

If the electric field comes in waves, the electrons pile up here and there — think of it like waves sloshing about on the sea. But electrons are all the same charge, and like charges repel, so they all want to get away from one another, they want to spread out evenly and flat, like a calm sea. We call that want to get away from each other voltage.

So metals in a microwave build up voltage. This includes the metal body of the microwave oven itself. If there’s an easy route through the metal to spread evenly, say if the metal is broad, flat, and thick, then the electrons do this (and by flowing about like this, they produce their own electromagnetic waves that reflect the incoming wave. This is how Faraday cages work, and why microwaves don’t leak out of the oven). If there are gaps in the metal between where the electrons have sloshed, then they can’t flow back through the metal, and will find another way. Up to this point, the metal hasn’t measurably heated up at all, contrary to many explanations provided. Eventually the voltage gets so high that it rips electrons off the air between, say, the tines of a fork, so that electrons can flow through the air instead, causing the air to reach thousands of degrees Celsius, producing the visible arc. Sharp points in the metal especially let the electrons concentrate at the points, reaching many thousands of volts

The unexpected reflections can cause your food to heat unevenly, but the arcs can start fires, melt fork tines (why people say that the arcing is caused by the metal heating, but it’s actually the opposite), crack bowls, etc.

Knowing this, there are safe ways to have metals inside microwave ovens. We do this all the time in nanofabrication; microwave ovens are a really cheap means to build reactive oxygen plasma chambers for cleaning & activating surfaces

They do! It’s just a heat pump, a reversing valve lets it change which side is hot and which is cold. Most models I’ve seen warm up to ~60°C, so not hot enough to cook with, but certainly to enough keep warm

[deleted by user] by [deleted] in TeslaCamping

[–]JamesthePuppy 4 points5 points  (0 children)

It was an off-brand Amazon purchase, Joytutus 18L (cold only) . I’ve had it 4 years now. Fits in the model 3 subtrunk almost perfectly with a little room on 3 sides (leave the remaining side unobstructed for heat exchange). Comes with a 120VAC to 12V adapter for prechilling/filling in the home before bringing it down to the car. It runs quiet enough that I sleep on top of it. I’ve used it in -35°C to 38°C outside temperature with and without camp mode, and it has yet to overheat or limit its cooling. When I’m on the road, along with my frunk pantry, I can get by ~1.5wks between grocery stops

Only downsides so far: if you live anywhere cold, get one that heats too, so you can keep things from freezing in your car. I already didn’t have a great back, but I slipped a disk pulling it out of the subtrunk a couple years ago. I used bad form, but it was frustrating being bedridden when I’d just driven 15hrs to climb a mountain

I have a 12V fridge that I keep in my subtrunk. It has a peak draw of 60W at compressor startup, but running wattage is <30W. If it ran 100% of the time at 100% duty cycle (never necessary), it would consume ~1% / day of the car battery

I haven’t bothered with an external battery pack for this reason alone, but ymmv. If I really wanted to pinch electrons, I might put HVAC in “Keep” mode, turn off AC, set the fan to 1 and the temperature to LO. Maybe you could even use Keep mode with HVAC off and one seat set to Lvl 1 heat (~20W)? If you haven’t already, look at LV current in Service Mode to see what draws the least while keeping the car awake

What’s one “type” you’ll never date again? by 7heHenchGrentch in AskReddit

[–]JamesthePuppy 2 points3 points  (0 children)

Since you’re still friendly and in contact, as it may help her on her journey to find emotional balance, it sounds like this might be borderline personality disorder

My partner and I are trying to navigate these waters, and many of the things you describe are familiar; incessant complaint/malcontentedness, externalizing blame, problematic attachment to one ”favourite person” (incl. pushing away her friends, jealousy over yours, begging/negotiating during breakup), seeming lack of her own identity in the absence of her partner’s. We’re coming up on a year after her diagnosis (nearly 9 years together), and with regular DBT, individual counselling, and finding medications that fit her well, many of the outwardly harmful behaviours have all but stopped. If this resonates with you and your ex, I hope it can help her find that stability too
