I think there was a time when he could have apologized for a dumb mistake and everyone would have moved on. It is world news now because HE chose another and unfortunate path - which probably has no route back to the sunlit lands.

gotta admit, that is a lot safer approach than trying some shit on the real thing

This could be for marine algae, which might have high iodine and sometimes high organic arsenic (though there is some debate over how toxic that is) - but freshwater algae are not necessarily high in iodine. Like spirulina for example.

You would think "I could stand in the middle of 5th Avenue and shoot somebody and I wouldn't lose voters." -DJT Jan 2016 would have pretty much filtered the US population into two camps long ago. The "swing" population that is reflected in every poll since then is a gaggle of . . . I don't know . . . forgetful? inattentive? I am trying not to be invective, no matter what.

he is not wrong about moderators being like "landed gentry" in a lot of cases; but on the other hand the blackout already did the damage. Time will tell if he is dead-man-walking, but I already deleted all my content (posts and replies) and unsubscribed from all. Some people may feel angst that the blackout did not "win", but it was a very useful occasion to focus on the reddit phenomenon and recognize our commoditization. I had been glad to contribute content, but if reddit is going to <do what they did> then I am done. That is all the win I need. I will contribute it here (lemmy servers) instead.

What the author is saying, I think, is that the inevitability of the tragedy is the right-wing concept. The concept of the commons is totally legit and the tragedy that can befall it from unregulated use is also clear. The right-wing concept that is dubious is that humans will self-regulate and do not benefit from governance.

Tthis is perhaps good news, but it does not amount to a change of course, unfortunately. If we have passed peak emissions, it is still a long way from net-zero emissions. Like if you pass your peak rate of overspending your salary, but you are still continuing to go farther into debt. Even when you get to parity between salary and expenditures, you will STILL have the accumulated debt and in the case of CO2, that debt is wreaking ecosystem destruction. Do not cheer this news.

Long ago, I was a midshipman on a submarine. The crew LOVED to watch submarine disaster films - with water spraying in all frothy and fire-hosey. But the reality would be a flooding time measured in fractions of a second, in most cases - people are not used to dealing with pressures in the tons per square inch except at the nozzle of pressure washers where the flow is tiny. So, on the bright side, most submarine failure deaths are quick ones.

The statistic of low Firefox use is based on accessing US government websites. Could it be that there is significantly LESS government site access by the population of users that prefer Firefox? As a corollary I recently read that game companies observed significantly HIGHER bug reporting from Linux users on Steam, not because there were more Linux-related bugs, but simply because that set of users were more likely to initiate bug reports. Of course Firefox is not Linux and Steam is not the world, but a statistic from a relatively narrow segment of the internet should not be assumed representative of the whole.

In economic terms, nature is often referred to as an "externality" - meaning, as you say, things which do not appear on corporate balance sheets - that are unvalued. We have collectively recognized that clean water in rivers is something valuable to society, and converted the externality of "use the river to carry away the pollution!" and "use the river water to cool the process plant" into actual costs: not by making investors put their money into riverine systems for future profit, but by requiring permits which restrict what can go into or come out of the river. We can, and sometimes do, manage the land in similar ways. I advocate for it, but of course I get a little anxious about the details if it comes to MY land!

I spent a couple of years in Guna Yala, the indigenous-peoples' territory of northeastern Panama. The Guna people live in towns on islands just offshore of the coast, and they farm and hunt in the mainland forest. When a Guna family wants to grow crops, they go with a village chief to the forest area near the village and identify a piece of land that is suitable. The chief approves it and records the location, and the family has it for three years. They can cut trees, plow soil, plant whatever. After three years, they have to abandon it and nobody can use that land for three years.

I feel very much that my land is not REALLY mine. I have stewardship. The people that had it in the recent past (20th century), did not treat it well and shame on them. But they are dead and gone, so they don't care I guess. I am treating it better and someone later will probably be glad to acquire it because of the great soil, healthy and perhaps valuable tropical hardwoods, and well-connected ecosystem. I'll be dead and gone so I won't care. It is IMMEDIATELY gratifying to live in this place and see it heal and prosper and that is all the return on investment I could ask. But I would at least say they should give me a break on property tax for land I restore to forest (even food forest). Maybe I will donate it to the Nature Conservancy some day, to lock in the gains.

In that case, Krasnodar and Rostov to Ukraine as buffer zones - maybe Belgorod and Kursk too?

I note that only one of the photos accompanying the article features PLASTIC rubbish. curious

at 9000 feet deep, the pressure is 273 atmospheres or 4100 psig - they never knew what hit them.

The article mentions hydrogen from electrolysis of water, but I think a bigger source in the future could be steam reforming of biomass. That is, when you heat biomass (plant matter, sewage sludge, maybe even municipal garbage) to about 300C in steam, the organic matter breaks down into simple molecules like hydrogen, carbon monoxide (highly flammable!), methanol, elemental carbon (biochar) and miscellaneous others. Some of those molecules can be recovered for important chemical feedstock (since we won't have petroleum or natural gas as feedstocks anymore, right?), and the gas can be fuel.

In the early days of natural gas use, towns would "reform" the methane (CH4) by reacting it with steam to make carbon monoxide (CO) and 3 molecules of H2 - a mixture known as "city gas". It is not new technology.

It is entirely logical to nationalize package deliver! We should have an organization that follows regular routes all across America and delivers whatever packages, etc. people need! We could call it something like UPS; maybe USPS?!

I get about as many deliveries by parcel post as by UPS. Nothing can stop the US Mail

The problem of democracy has always been the short attention span of the electorate. People make emotional decisions; "throw the bums out" - which of course it is sometimes right to be frustrated and take a new direction - but sometimes cooler heads must be allowed to prevail. We democratically chose to have that non-democratic institution, no different than various other government institutions that we put in authority over our day-to-day activities (police, and a whole range of other government "services", even the IRS!).

top slab is about 230 or 240 pounds. Wood base is only about 15 or so; light. I made no attachment between the concrete and the wood - just gravity.

this inspired me to paper over all my old comments and posts with clippings from random washington post articles from today. A labor of ... love

yep, these are all marine algae. I think the market will develop and more consistent products (and no doubt thorougly coated with preservatives) will become prevalent once dear old General Mills, ConAgra, and their like enter the fray.

fwiw, this story is also covered here, imho a more credible source: https://www.aljazeera.com/news/2024/2/1/palestinians-demand-international-inquiry-after-mass-grave-found-in-gaza

Monsanto of the Sea?! This article fear-mongers vague "unintended consequences" as an ethical shortcoming of what they admit seems like a pretty solid concept for sequestering carbon - while never once mentioning the major unintended consequences of NOT trying to sequester carbon.

Capturing carbon in biomass is always a somewhat risky proposition by itself, because biomass can decompose and re-release the carbon. But even if the permanence is low right now, developing the skill of seaweed farming or any other carbon removal technology is a win - we can figure out how to increase permanence later as we scale up. No technology is fully developed at inception.

The issue with marine algae is not mercury, but arsenic. We know inorganic arsenic is toxic, but marine algae accumulate arsenic in organic molecules, which some studies seem to show that is less toxic or even non-toxic. But some effects of arsenic toxicity are long term, like cancer, and apparently it is not a decided issue yet. There has been arsenic in the sea for a long time, and marine creatures of all sorts have evolved to deal with it in various ways.

I watched some youtube videos about people growing spirulina in backyard pools. They tell all about how to do it. One guy says normally he would dry it to powder and add it to "regular" foods. But he sometimes just eats it as-collected. It has no taste, or sometimes a faintly "fishy" taste

whatever does not kill us, makes us stronger? LOL I think it might be OK if you rinse it very thoroughly - in a way it might be like beer-brewing. In olden times, the quality of water was not easy to assess - it might make you sick. But beer, if it tastes good, is proof that conditions have been achieved for fermentation and therefore, bacteria could not be present in significant numbers (else the beer would sour!). Maybe a healthy spirulina population in a pond is like that? I suspect it is true, but I have been unable to develop a spirulina culture so far (and partly from lack of serious effort).

I built it to fit some glass that was about the right size, so not really a design others would emulate precisely. But a standard sheet of galvanized sheet metal is about three feet by six feet, so four 10-foot boards will nicely make the "box". I used 1x2 for the corner bracings (just glued and screwed), window frames, and dryer trays. I had made an earlier version with a sheet of translucent corrugated roofing for the lid, and that heated up quite well, too. The legs were just some scrap - I think the angle of the box should be around 45 to achieve some natural convection and good mid-day sun collection area. But it could vary with one's latitude I suppose - in a more northern clime (I'm at 20N), a more vertical "cabinet" might work - the dryer trays would be shallower, but convection would be better. I am not sure the vent stack makes any difference.

You can count on this though: spending on something will be way up.

These are some good points. The more traditional engineering disciplines have a depth of methods and practices that developed over time, and software engineering is - what? only maybe 50 years old or so? I have not worked with software engineers, but with all other sorts, so I know if there is engineering going on in software development there will be certain methods in place: preliminary designs that senior teams evaluate and compare, interdisciplinary review so the features of design that "work" for one objective also do not detract from others, and quality control - nobody works alone - every calculation and every sentence and every communication is documented, reviewed by someone else, and recorded permanently.

I can imagine that some software engineering efforts must bring some of these tools to bear, sometimes - but the refrain in software development has long been "we don't have time or funds to do it that way - things are moving too fast, or it is too competitive." Which maybe all that is true, and maybe it can all be fun and games since nobody can get hurt. So if game developers want to call themselves engineers regardless of whether they follow, or even know about standards of their industry (let alone any others'), no harm, no foul, right?

An old friend of mine wrote the autopilot software for commercial passenger jets - though he retired about 25 years ago. He was undoubtedly engaged in a project that nowadays would be dubbed software engineering. The aerospace company included him in the team with a whole slew of different engineers of all sorts and they did all the sort of engineerish things. But I don't have the impression that much software goes through that kind of scrutiny - even software that demonstrably deeply affects lives and society. In a way this is like criticizing the engineering of an AR-15; what were the engineers thinking to develop something that would kill people?! But it seems like with software, the development has effects that are a complete shock even to the developers: facebook algorithms weren't devised to promote teen suicide, it was just an unforeseen side effect for a while.

I think it is time for software engineering to be taken seriously. And there is professional licensing. The problem is that corporations are dubbing their staff as software engineers a lot of times, when there is no licensed engineer in the building and there are no engineering systems in place. It is fine for me to say that I engineered the rickety shelves in my garage, because I'm an engineer and therefore it must be so, but that is some sensationally bad logic. They could collapse at any moment - I'm a chemical engineer.

I have plain ol' Ubuntu LTS and I do not recall a Steam crash in a decade. Playing with Nvidia GPU on AMD Ryzen in recent years.

you want proof that accumulated carbon dioxide is causing environmental destruction?! https://www.ipcc.ch/report/ar6/syr/downloads/report/IPCC_AR6_SYR_SPM.pdf

actually, you better wait for the pics to say that . . .

If you think about it though, coming into a kitchen and saying "it smells good!" is OK; if the odor is bad, maybe lack of carbon filter is not the problem! lolz I have a recirculating fan, but I don't think it does much odor trapping. Odor molecules come in all sorts of forms - some adsorb to carbon and some don't. Although activated carbon has a large capacity considering the size of the particles of carbon, it can't do miracles. Furthermore, I suspect the carbon is encased in trapped oil long before its odor-absorbing capacity is exhausted (though I guess that depends on one's cooking style).

(I posted words to this effect many hours ago, but that post seems to have been lost)

yes, a vent stack; it helps air flow. There are three two-inch (5cm) holes at the bottom end to admit air. An earlier iteration of this design had screens over the holes to keep critters out, but it turned out to not be an issue so we have not screened the holes on this unit.

We saw a design for a solar dryer popular with Peace Corps volunteers - a heat-collector box with a small dryer compartment on top and three little trays in a stack. But I thought, why not put the dryer trays right inside the heat collector? I just checked the temperature and with partly-cloudy skies, it is 50C in the box.

wha? I use Firefox and I haven't seen or heard of Pocket in years.

Engineers describe heat transfer with a "heat transfer coefficient", and the rate of heat transfer is this coefficient multiplied by the temperature difference. So you can calculate what the heat transfer coefficient must be by measuring room air temperature initially, water temperature initially, and then running your system for a little while and measuring the room temperature again. The smaller room area you can cool the more accurate this will be. You will need to look up heat capacity and density of air (easy to find), and the temperature change of the air with the volume of the room and the temperature change will together give you an amount of heat you removed from the air to the water. Simple!

I rotated 90 right and the picture was 180 from OP, so I rotated back 90 left and tadaa:

maybe there is a way to rotate images, but I have not yet discovered it; sorry about that. It looked OK as an original. Once you preview, it is not possible to edit? I am noob.

maybe you are a little short on RAM? OS and apps keep growing, but installed RAM does not grow with them. :(

I tried disabling Privacy Badger - that sometimes interferes - but no help
