I agree with all of this. At the same time, I think that, in most cases, people should allow their body to adapt to heat, if they are healthy enough to do so. Most people can learn to be comfortable in higher heat than they believe, although some people have medical conditions that will make them more susceptible to heat exhaustion and heat stroke. If you can get by without it, you should. If you’re at risk by not using it, don’t feel guilty.

(FWIW, my office only has a/c because I have a very, very large printer in here, and it tends to have head strikes and scrap prints out if there’s no climate control. But since I’m not printing at the moment, the current temp in here is 82F.)

On top of that, as we experience higher temperatures, many people also crank up their air conditioners—which emit more heat-trapping greenhouse gases into the atmosphere.

This is not correct. Air conditioning units do not ‘emit more […] greenhouse gases’. Air conditioners use a refrigerant–usually R134a–which does have a high global warming potential (GWP) compared to methane or CO2, but that refrigerant is in a closed loop; it’s not going anywhere unless the system is damaged. Most a/c failures aren’t from refrigerant leaking out of the system, and the system no longer being able to effectively transfer heat, but from the compressor motor failing. When the compressor fails, in most cases you can evacuate the refrigerant, replace the broken part, and then recharge the system. (The fact that they can be repaired doesn’t mean that they usually are repaired. Which is shitty.)

What is true is that a/c units emit heat themselves. An air conditioner moves heat from inside a space to outside of that space; in the process of doing so, the a/c unit itself is creating an additional small amount of heat from the function of the compressor motor, electronics, etc.

Beyond that, most electricity that’s used to run a/c systems–and every other electrical device–is produced from burning fossil fuels. So if there’s more demand for electricity–such as from a heat dome that has everyone running their a/c full-time–then yes, more CO2 is going to get pumped out into the atmosphere. But if your electricity is coming from sources that are largely emissions-free, like solar, wind, or hydro, then air conditioning is a negligible source of heat.

tl;dr - don’t feel bad about using your a/c when heat rises to dangerous levels; agitate at a local, state, and national level for renewable, carbon-neutral ways of generating electricity, and for more efficient use of electricity.

I dunno, when you’re talking about really specialized niches, there are still plenty of forums. Like, 600rr.net; it’s dedicated to nothing but Honda CBR600RR motorcycles. If you have a problem with a 600RR, the answer is probably there, and the forum is still ticking along because it’s just too hard to find those super-niche answers on Reddit. Want gun content with a healthy dose of homo/transphobia and christian nationalism? AR15.com has you covered. Want to talk about the minutiae of reloading and be autistically-focused on long-range accuracy? SnipersHide.com is your place. (They’re a bit fuddy though.)

Sure. If you’ve abused it in some way so that it doesn’t take or hold charge, then you might have to pay for a replacement battery. But I think there would be an implied warranty when you’re given a replacement, that the replacement was fit for service. And the company might just have to roll the cost or replacing batteries every so often into their electricity pricing models.

That’s like asking who owns a propane tanks for your grill. You own it while you have it.

When you get a new batter, you own the new one, and relinquish ownership of the previous one, paying for the electricity that’s on the new battery. AS LONG AS the battery that you’re relinquishing is substantially identical to the new battery.

Create a multi-part archive (…probably about 250 parts…) with a strong password, upload each part to whatever the current equivalent to Megaupload is, and let them download it at their leisure.

With no accounts on either end, should only take about three months for each to be complete.

Alternatively, you could put it on a thumb drive and drive it over if they live fairly close.

I’m pretty sure you’re correct, although I believe that the part that’s capturing photons also needs to be heavily protected from the environment, and you also need something to prevent to many photons from getting to it and burning it out (e.g., almost all gen 3 NODs are autogated so that someone shining a flashlight at you won’t wreck your image intensifier tubes.)

It’s one of those things that can get pretty overwhelming to try and research as a consumer, because it gets really technical really fast.

Okay, so you’re talking about the IR that most people would refer to as thermal, rather than the IR that’s technically NIR, and is used in most image intensification. My mistake; as you say, these things get slippery because most of the time people aren’t talking about specific wavelengths and frequencies.

Yes, IR-as-in-thermal is going to be stopped by most glass. IR-as-in-NIR-for-NODs is not. The IR lasers and weapon lights that show up very well with NODs are definitely not visible to the naked human eye, so they’re outside of the visible light spectrum, and get generally labeled as IR, even if they’re outside of the spectrum of IR that’s used by most thermal optics. (It would be interesting to see if a Steiner DBAL could illuminate an area that had low IR for a FLIR camera.) And yes, for that, a red dot sight will work, because it will be set to very, very dim; too dim to be seen by the naked eye.

Tons of job listings have barely any presence outside of LinkedIn. And yeah, quite often employers will want to see some kind of professional something online.

First: I’ll believe it when I see it. Every so often pie-in-the-sky claims of this type come out, and they often end up not being feasible, even if they’re technically possible.

Second: if it is feasible, given that gen 3 night vision tubes have remained stubbornly expensive, I would not expect this to be cheap for a long time.

because regular glass is usually opaque to IR.

I’m almost 100% positive that this is not correct, because I’ve been driven around by someone wearing PVS-14 NODs with no headlights, on dirt roads, in a commercial van. (Edit - most red dot sights also work very well with NODs, and those have one or two layers of glass, depending on which type of system it is. The sights that don’t work well usually can’t dim the dot enough to avoid massive bloom.) Glass is mostly opaque to thermal though, and a lot of glass significantly reduces UV.

I dropped Instagram, and couldn’t be happier to have left that cesspool behind. No […] LinkedIn, […]

Unfortunately not having any presence on LinkedIn makes it quite challenging to find professional-type jobs. :/

It is, yes. They do a ton of really small updates all the fucking time now, sometimes breaking critical shit, sometimes fixing things. (I don’t remember which version it was that ended support for PANTONE; now you have to pay for a subscription to PANTONE also, and the plug-in is trash and buggy as hell.) Since it wants to be always connected to the internet now, it’s more of a pain in the ass to pirate, although it’s likely still possible.

I have to use it for my job, so my company pays for it. But TBH, if you’re an industry professional, there’s really not any viable options on the market. Half the stuff clients send to me are in proprietary formats.

Still workign for me. I’m using FIrefox in incognito mode, a VPN (I use a VPN for everything), and uBlock Origin.

720p? Pfffft. 240i. Rip them in ‘2014 YouTube over 2G’ quality.

A guy that claimed to be very familiar with that engine indicated that the problem is the design of the piston heads. He said that they have very short skirts, and as the rings wear, the piston head twists and pushes the skirt into the wall, causing the wear lines I’m seeing. The solution–once/if I can get the cylinders re-plated–is to replace the pistons with something like Wiseco. Or if I need to replace the entire engine (because you can’t just replace the top of the crankcase, it has to be replaced as a complete unit), then do the same to prevent it from happening.

If your engine is substantially identical to mine, then you might see the same wear pattern in the cylinders with a borescope.

Also, FWIW, I called a place near me that was suggested for machining services (they actually send crankcases out for replating), and when he heard the mileage, he was surprised that I’d put that many miles on it. I guess most people just don’t put that kind of mileage on motorcycles. :\

That’s a bummer. I know that when I look on a lot of forums, everyone always says that modern motorcycles (not Harleys!) will last forever as long as you do basic maintenance. But it sounds like ‘forever’ for most people doesn’t include putting on 20,000 miles in a single year. (That was the year I went through three sets of tires.)

That makes a lot of sense. And I can agree that I have an emotional attachment to my motorcycle, both because of the money it cost, but also because of the time I’ve put into it, and the ways that I’ve modified it to make it ‘mine’.

After talking to a lot of people over the last few days, the most rational approach seems to be to buy a replacement motorcycle, and then repair this one as I can, assuming that I can find a reliable place that can replate the cylinders (or bore them to 69mm and then plate them if the scoring is deeper than it appears). That way I’m not feeling stressed about it not working, and if I fuck it up, it’s not a tragedy but a learning experience.

Commuting and recreational; no track or racing. I think I’ve only ever hit the red line a handful of times, and I’m usually 2-4k rpms below it.

First: It’s a site dedicated to electric vehicle promotion. So it might be a tiny bit biased.

Second: Their criteria was for their claim was, “13 percent of the cases with starting difficulties are electric cars”. Well, golly gosh gee, how surprising that an electric car would be easier to start in cold weather, since as long as you have any juice left in your battery, it’s gonna go. You don’t have problems like diesel fuel gelling, or oil turning into molasses. (If it gets cold enough, your battery might freeze solid, and then you have real problems.)

Finally: “[…] electric vehicles are involved in roughly 21% of all its cases so far in 2024” Given that Norway is roughly 25% electric vehicles–they don’t give the exact percentage in the article–that’s… Pretty much in line with overall percentages. It might even be high, given that EVs are more likely to be new than ICE vehicles.

If we’re going to do cars–and I don’t think that there’s a reasonable alternative that can be brought to bear in a reasonable time–then I’m all for electric. But this isn’t a great way to promote them.
