There is a new process for treating wastewater sludge that destroys the microfibers, so that is good news at least. I think it may be expensive, of course. It is called “hydrothermal carbonization”. Basically put the sludge in a giant pressure-cooker and the heat breaks the plastics into carbon and some water-soluble residual molecules which can go back to the start of the wastewater treatment plant to be biodegraded. But like others say, the main source in general is tires - not sure if they know whether tire microplastics are the main source in agricultural land though.

From the immortal Journal of Irreproducible Results, “The Data Enrichment Method”: “. . .its principal shortcoming is that before the enrichment process can be started, some data must be collected. It is quite true that a great deal is done with very little information, but this should not blind one to the fact that the method still embodies the ‘raw-data flaw’. The ultimate objective, complete freedom from the inconvenience and embarrassment of experimental results, still lies unattained before us.”

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

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

In the US, stove burners are rated in the confusing units of “BTUs” which is actually a unit of energy, not power. When they say BTU, they mean BTU/hour. The highest-rated burners on a typical stove are about 10,000 Btu (per hour), but high-end stoves can get up to about 18000 - that is equivalent to about 5000 watts. My single-element induction top is only rated for about 1000 watts. So although it heats and cools rapidly, I suspect it is not up to the demands of wok cooking (unless one wants to cook only very small portions).

not Chinese, but I cook a lot with a wok. I also have a single induction cooktop and surprisingly, the wok has enough iron to work with it while some old cheap conventional cookware did not. However, wok cooking needs to be hot all over the wok and not just in that little point where the wok is close enough to the induction coil.

I have a conventional propane stove which I need to keep, because here in Puerto Rico the power system is quite unreliable (especially during a bad hurricane year). But the conventional stove burners are not really hot enough. With a 1/16 - inch drill bit I could increase one of the burners capacity substantially. I painted the stove knob red so people have some warning when they light that burner! It burns more gas, but wok cooking is really fast, so in the long run it is probably more efficient than lots of other cooking approaches.

I would definitely consider a wok-shaped induction heater. Induction heating is quite remarkable.

I have heard this, and I can imagine it is true, but have you seen any analysis? There must be a large crew traveling and lots of equipment - transportation is a big user of petroleum in general – for entertainment. Though they say the entertainment is good.

Swimming pools are normally constructed empty. They were withstanding surrounding soil before they were filled, and concrete strength increases with age (for about 90 days, typically). On the other hand, a sunken structure like a pool that is roofed over, becomes a “confined space”. Unlike a typical structure, heavier-than-air gases cannot escape from the pool. Such gases could originate from the drain system or flow from leakage outside the pool area. For examples, leaking propane or various gases from sewer lines in the vicinity. A sunken greenhouse would almost certainly be a building code violation for that reason. If you build it, ventilate it by means both active and passive and do not enter if you can’t verify that ventilation is working.

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.

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.

Thank you for this correction. I will make a note that professional engineering has nothing to do with engineering - I don’t know how I have been so confused for so long!

I think engineers have been held liable for the soundness and fitness-for-purpose of what they “engineered” since ancient Rome - though they have certainly been called upon to engineer a greater variety of things in the past couple of centuries. And I think if someone proposes to engineer software, I am all for that! We could do with a great deal more of it in fact. And let’s dispense with this perpetual disclaimer of warranty for merchantability or fitness for any particular purpose, and such terms. If an engineer designs it and it does not work, the engineer is generally held to be negligent and liable . . . except if they are a software engineer, of course.

this seems to reflect the simultaneous co-opting of the titles “architect” (one who designs physical edifices such as buildings) and “engineer” (one who applies math and science principles to problems of infrastructure and industrial production). We all understand what is meant by design, but that does not mean a software design must be devised by an “engineer” or an “architect” anymore than an interior design (though there are also some self-styled “design architects” roaming about). So is it possible to say what is different about software development and software engineering without saying the engineer is an architect? Is it that software developers do not design anything (which in its simplest terms is ‘artful arrangement’)? That seems arbitrary - though I agree that there can also be a fine line sometimes between, say, architecture and structural engineering.

How often in the software industry is the title “engineer” a sop to give applicants a flashy title; and how often is there actual engineering involved? When I worked as an engineer some years ago, it seemed inconceivable that software development would become actual engineering because how could the engineering standards of care and professional liability ever be imposed? Today, virtually all software is either privately licensed or open source - there is no such thing as public software infrastructure under the development supervision of a professional software engineer (as far as I know). So I guess Mozilla can call their software developers anything they like, but it seems to be an ongoing cheapening of the engineering title - like why not call this position Chief of Software Surgery? Lead Software Counselor?

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

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.

You don’t have to use Google at all. They are pretty ubiquitous, so you have to make a little effort - search with another tool (I find duckduckgo to be quite satisfactory). Although Youtube has the lion’s share of the video, there are other places to go. It is the same with all Google products.

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

This is an interesting issue - I worked as a high school teacher for a while and all the “real” teachers were always discussing the idea of critical thinking and how to teach it. It seemed to me the critical thinking lessons were simply the assignments to do something the students did not know HOW to do. The admonition “Well? Figure it OUT!” was the driving command. So in a way, life’s challenges are everyone’s lessons in critical thinking whether they realize or not. To be sure, we can prepare children better or worse for those challenges - in some degree by whether they learn rote facts in school, or spend more time in actual problem-solving and learning to do collaborative activities.
