When technology can solve a problem equivalently well in so many ways discussion and debate is the way to learn from the experiences of others to help navigate your own course.

When it comes to adult learning, some people with some topics prefer to only know the answer of what they’re after or other times want a bigger picture.

Last but not least learning to read the code and system design decisions of others are both required for competent software development.

The part that stack avoided is maximum value comes from is understanding that decision making is the key in a lot of the underlying intent of users coming there … not just a snippet of code in system design.

Not know what you should be looking for or if there’s other ways to do things is a big lose in the development of software engineers.

How do I know this beyond my subjective interpretation and preference?

I was an early user of stack overflow.

It was a heavy time of software development, and I could easily spent 4-6 hours a day on it. So I decided to write. I learned so much, and shared anything I could. It really was a great early community.

I really disliked Experts Exchange and it was one of the major inspirations for SO to happen.

Little by little, I noticed some of my posts of hard earned lessons attached to a solution, started getting locked down.

People deciding how things should be interpreted one way. Correcting answers they don’t understand.

Answers started getting rejected. Context had no value. That’s not a great recipe for success.

The strange thing is I still sit in the top X percent of stack users for not having answered anything in a while, and still get upvotes and comments.

How to schedule multiple parties to ensure eveyrone has dace tkme?

Sorry, explaining steps in English is not code or acceptable. It apparently can’t be translated to different programming languages.

Software is for people in the real world, not strictly a technical pursuit.

SO started their network of other sites but the bar to entry was too high. There’s lots of extremely valuable but esoteric design knowledge that remotely being aware of or having access to can be tremendously helpful.

Stack overflow didn’t understand or care it was helping system design to be better.

Architecture goes bad in hand with code and I don’t know how you can talk about either effectively on the whole with the ability to refer to the other. With out it the trees don’t always become a forest.

I don't have anything rigorous, but I can say that I see the usual ~4x speedup when using rdflib to parse large files so that a 20 minute workload in cpython drops to 4 or 5 minutes when run on pypy3.

I just reran one of my usual benchmarks and I see 2mins for pypy3 (pypy 7.3.12 python 3.10.12) peak memory usage about 8gigs, 4.8mins for python3.11 (3.11.4) peak memory usage about 3.6gigs (2.4x speedup). On another computer running the exact same workload I see 6.3mins and 19mins (3x speedup) with the same peak memory usage.

I don't have any numbers on the dataset pipelines because I never ran them in production on cpython and went straight to pypy3. It is easy for me to switch between the two implementations in this context so I could run a side by side comparison (with the usual caveat that it would be completely non-rigorous).

I also have some internal notes related to a project that I didn't list because it isn't public, isn't in production, and the benchmarks were collected quite a while ago, but I see a 4x increase in throughput when pulling large amounts of data from a postgresql database from 20mbps on cpython 3.6 to 80mbps on pypy3.
This is what I see. The screen right after you select the room type and reservation terms has the total clearly listed. I do not feel like I was "hoodwinked" or "led on", on the previous pages it clearly says there will be resort charges, and prices are almost always excluding tax in the US.

>The premise that they guarantee a "best rate" is a largely empty one.

I have never found a hotel room as cheap as the rewards member pricing from a third party, and that is what a guarantee is. Does not seem empty to me, they deliver what they promise, and being a rewards member is free, and zero cost since they already have all your information anyway.
> Lithium ion not good enough, find we'll find a better battery.

Well, then get back to us when you find that battery. Unfortunately, simply finding a new battery chemistry that has an order of magnitude better energy density is easier said than done.

> Hydrogen however is just that: hydrogen. Notice how low it is on the energy per volume scale.

You're looking at uncompressed hydrogen. Hydrogen at 700 bar has several times better energy density than lithium ion batteries, and over 1000x as much energy by mass. And lower mass means you need less fuel since the craft is lighter.
Were expectations too high?

> "...huge companies with thousands of programmers working for them practically crying and begging to have a feature added to software..."

One clueless employee, almost certainly without the knowledge of his cow-orkers or managers let alone any kind of authorization to represent their employer when communicating externally, writes a dumb email to a FOSS project and suddenly the tech commentariat is all abuzz about "$BIGCORP (the whole thing) is 'practically crying and begging' to $FOSS_PROJECT for a feature"? Surely there must be a name for this fallacy and, if not, there should be. The organizational hivemind fallacy perhaps?
It's really not "trivially easy" to get in contact when the operation is run by a government or a corporation (even less).

At best they "hear you" and "will take it into account", then keep on doing what was planned. At worst they treat you like an idiot or a lunatic. And it's not like the company hired to do the work is going to listen to some random person telling them how to do their job.

Only thing I've found works is volunteering for orgs that actually do things right, if you can find one.

That or just planting yourself at 2 in the morning ;-)
Who Paid for a Mysterious Spy Tool? The FBI, an FBI Inquiry Found
This project is what killed nuclear in the US. Not regulations, not the NRC, just plain old incompetence, bad planning, bad EPC, bad design.

The AP1000 was supposed to be a "modular" design, where most of the difficult welding could be done off site and delivered complete, with paperwork. And failure in this modularity is what caused the project to be such a flop, and essentially kill all new large nuclear in the US (people are trying "small" modular, but their target costs are still far too high to be economically feasible).

See, for example, this 2017 report on just one aspect of what went wrong:

https://www.enr.com/articles/43325-witness-to-the-origins-of...

> To build the first new nuclear reactors in the U.S. in three decades—South Carolina’s V.C. Summer Units 2 and 3 and Georgia’s Plant Vogtle Units 3 and 4—the design and construction team would face a steep learning curve. However, says Hartz, learning wasn’t much of a priority in the rush to start work at Lake Charles. “They were clueless” about the complex geometry of nuclear welds, the nuclear supply chain and the need for a nuclear safety culture, he notes, adding, “I wasn’t a whistle-blower. I was just a senior procurement manager who was concerned.”

> Westinghouse would issue drawings to Shaw Nuclear in Charlotte. When Shaw reviewed the drawings and asked Westinghouse to correct a detail, problems ensued. The work processes were unnecessarily complicated by the separation of the team members. Giving an example of how the process got out of hand, Hartz says that, if a design called for a 3⁄8-in.-wide, 12-in.-long fillet weld, the welder might make it 14 in. long. “Instead of having Westinghouse right there saying, ‘That’s no problem,’ ” recalls Hartz, “we had to write a nonconformance report that was processed and reviewed by Shaw and then sent to Westinghouse for disposition. It was insane. From Lake Charles to Pittsburgh to Charlotte then back to Shaw Modular before the red nonconformance tag could be taken off, saying it’s OK now.” He adds, “Each change went through the same tortuous path, taking months and months.”
Yeah, I've been trying to minimize lawyer costs :) Clerky has helped tremendously with that, but maybe I finally need one. Though I imagine this sort of thing is generally pretty boiler-plate.
That's fine but the user has no way of knowing if a third party is party to the communications or not. Surely they should know?
> This isn't complicated: marijuana is addictive to some people, but making it illegal doesn't solve that problem--it should be legal. But it's apparent that's too much nuance for the average politician.

If weed is illegal and the law is enforced then fewer people will use it and fewer will become addicted. That might not "solve" the problem but it helps.

I'm not arguing that weed should be illegal, only that making something illegal reduces its use.
I can't drink any caffeine either. I'm a fairly large guy, but even 1/4th cup of coffee at 6:00AM causes the same problems - my Apple Watch starts complaining that I have high HR, I get anxiety that blocks me from doing productive work, and my sleep schedule gets completely screwed up.
The BBC isn't hosting anyone else on their instance (nor can I think of a reason they would want to). As I understand it it's just a way for their activity to be visible on the fediverse. That should make their infra costs minimal; they don't have moderation of comments/replies; and federation/defederation wars will only affect the specific other instances which choose to defederate from the BBC. Your third point is valid but that's why this is an experiment.
A question of "Have you tried..." might be the precursor to an offered opinion. Maybe their friends have been successful at that exact thing and the opinion is moot. But if the answer is no, perhaps that's the point at which it might be suggested to try.

There's no controlling that is necessarily suggested by their comments. Certainly such questions can be asked in bad faith but it might be assumed that OP isn't doing that.

I have taken so much inspiration aviation industry when designing and operating software system.
In addition to the inspirations mentioned in this blog, I find the idea of "antifragility" in aviation quite fascinating, where every near miss is studied, documented and checklisted across the entire aviation industry. This means that every near miss improves the resilience of the entire industry. We need to build similar means of learning from others' mistakes in complex software systems as well.
It's still a tax even if you don't incur it by avoiding the activity.
I use both MySQL and Postgress. SHOW TABLES, SHOW CREATE TABLE, SHOW DATABASES is not SQL and takes too long to type. \dt, \df, \dv is very fast but I almost always mess up. I think SQLite's .tables, .schema, .databases is a good middle ground.

OTOH we have many connections writing to the database to many tables, so one process per connection is not necessarily to our advantage. We're still using MyISAM to store time series data because it's fast. Maybe Aria is a better replacement. Too bad MySQL or MariaDB doesn't have a time series extension like Postgres' TimescaleDB and the GIS functions are quite basic. On MariaDB, some of the useful functions compare the bounding box instead of the actual shape¹. MySQL 8 is somewhat better in this regard². It's good enough to store POIs but not great to intersect a linestring to multiple polygons and get a useful distance.

Also no LISTEN/NOTIFY mechanism in MySQL.

If you stretch out the CMB across the volume of the entire universe, it seems plausible it would be pretty faint. That r^-3 term on the energy density is pretty small when r is of order ~100 billion ly or more.
I'd rather use my TVs flavor of android than Windows, honestly. I just don't see what that would buy me.

I get running a Linux media server, don't get me wrong. But a dedicated windows machine for my TV seems like a waste of time and money when my TV can already do whatever that box would. It buys me very little.

On the brink: Namibia’s wild desert horses
Okay, I probably didn't understand JAMstack, even though I say to folks that I use JAMstack. I am not a professional web developer, but this is the reason why I thought I was using JAMstack:

The reason I like JAMstack is because:
- It is free.
- It adds modularity to a static site.
- If you want to provide an API service and your website just makes the API data look pretty.

It is free.

Netlify is free to sign up without a credit card. What else would you like me to mention? Everything else costs $5 a month or more. I am cheap. Cloudflare is free, Firebase is free, etc.

Modularity in a static site generator.

You know what is really cool and just works? Good static site generators. But sometimes, I would like to add some technical features to it, for SEO or fun. I would like to add components that focus on server-side computation a bit. However, it is not easy to do when you start with a static site.

So, what I will do is simply write an API and connect it to the site with a simple API call. I can handle all the complicated tasks in the backend and send some data to my website, where it will be displayed in a table.

If you want to provide an API service and have your website display the API data in a visually appealing way, this may not apply to most people. However, in my line of work, I used to focus on building APIs exclusively. People were not interested about the how site looked. They sometimes required authentication, a table, and some visualization and sorting features.

To simplify the process, I would handle most of the tasks on the backend, with the website mainly fetching data from the API. It would consist of templating syntax and occasionally handle state management, as it was not practical to filter the data on the backend.

---

So, that is how I used JAMstack. Can I do better? Eh, not really. I am not a web developer. I build APIs that sometimes need some visual representation. With Netlify Auth, Netlify Function supporting Go, Cloudflare Pages, etc., I don't see myself throwing in the towel on JAMstack, even though I might be missing the entire point here.

Embracing the two-year cycles that web developers have about everything being bad and everything being shit is not for me. And yes, this is a cycle, and this is a fit. You will see after two years, some dude with 120K followers on Twitter will announce "we have re-embraced everything that is wrong with PHP because of 4chan memes, and here is this web5 stack that will fix everything."

In web development, the only people I respect are those who have been using a 5-20 dollar/month VPS for more than a decade. They are not on Twitter, don't check HN except for weekends and they don't even do webstack-evangelism.
I don't really understand. Which figure is 10 pages down in the example that I linked?
> undirected transformative experiences

Going in without a therapist doesn't necessarily mean the experience is undirected.

Even during an intense psilocybin experience, people typically retain some degree of agency and control over their actions. In most cases, individuals on a psilocybe trip can still make decisions and perform basic tasks, though their perceptions and judgments might be altered.
Trees almost everywhere will create more trees if left to themselves. One oak tree produces lots of acorns.

The problem is mankind. We like to interfere. In a way many tree planting schemes are an indicator of this interference (hubris?). We just need to let nature do its thing in most places.

There are of course some places that need help and people can help here (watering, stopping logging, species diversity, grazing animal protection etc) but generally nature will do it for us if we let it.

Small scale planting schemes are great for community and education too.
You really couldn't have picked a worse weekend to make this call. Barbie, alone, is setting record numbers that are showing a pretty good recovery for the past few years.

No. And the thought of having to deal with them, whoever they are, makes my skin crawl. I'd rather eat the entire cost of it twice than do that.
Thank you. It’s always destabilizing when so many people simultaneously miss what I thought to be a clearly-stated point.

Wouldn't the big advantage of GMO trees be ones that grow in non-boreal regions? But I gather genetic engineering for most tree species is limited by the slow reproductive cycle (oak trees take 40 years to produce acorns, and they're not even close to the slowest to reach maturity).
Now I understand the concerns you brought up, and I see how it complicates things. Thanks for clarifying.

There's something to that, but I think that there have also been studies that show that regardless of policy, about the same percentage of the population uses drugs and can switch to different drugs when one gets too difficult to acquire.

Not an expert on this by any means tho.
> That's because the loophole doesn't exist. It's an obviously flawed interpretation of the 2018 Farm Bill which isn't likely to hold up in court when it's finally tested there.

It's been tested somewhat (interestingly, in a trademark case which rested on whether the infringed trademark was for a legal product) and it has succeeded at the Circuit Court level. AK Futures LLC v. Boyd Street Distro, LLC, 9th Cir. No. 2-56113 (May 19, 2022):

Importantly, the only statutory metric for distinguishing controlled marijuana from legal hemp is the delta-9 THC concentration level. In addition, the definition extends beyond just the plant to “all derivatives, extracts, [and] cannabinoids.” 7 U.S.C. § 1639o(1). The use of “all” indicates a sweeping statutory reach. See Lambright v. Ryan, 698 F.3d 808, 817 (9th Cir. 2012) (“The common meaning of the word ‘all’ is ‘the whole amount, quantity, or extent of; as much as possible’ . . . .” (quoting All, Merriam-Webster (online ed., visited Oct. 4, 2012))). This seemingly extends to downstream products and substances, so long as their delta-9 THC concentration does not exceed the statutory threshold.

Of course, as this was on an appeal of a denial of a preliminary injunction, the ruling is framed in likelihood of success rather than absolute terms, but its a pretty strong negative indicator for your argument that this is a clearly incorrect interpretation that no court would take seriously, since both the District Court and the Circuit Court very much took it seriously.

But the internet did change things? Even crypto is debatable. BTC still exists and still has pretty high value, just not as high as at its peak.

TBH, I'm not sure how to quantify housing bubbles either. I'd bet most of the country has much higher home prices now than in 2007. I bet they were higher than 2007 in most places and most years between then and now too.
> And large scale renewables + battery storage are good enough.

I wish this were true, but I haven't seen convincing evidence that it is. Up here in Minnesota, we heat our homes with natural gas. Once that's converted to electric, that's a _lot_ of energy to generate and store, and it has to be absolutely reliable for six straight months or you're talking mass death. Nuclear seems like a perfect fit for this scenario. I think it's a poor choice to take it off the table.
The NRC was established just about when the first nuclear buildout collapsed under the weight of its own foolishness. Massive cost overruns did nuclear no favors whatsoever, clearly inadequate safety (especially on those first generation BWRs; hello Fukushima), and (most devastatingly) the deregulation of the US electricity grid, with PURPA (in 1978) and later steps opening grids to non-utility providers. Nuclear projects that would make sense for a monopoly utility (hey, let's boost the capital spending to increase our regulated earnings) no longer made any sense in a competitive market.
It's not O(N^2) is it? It can be a continuous line of ice being pushed up. Depending on the weight bearing ability of the lift and digging capacity, you would figure out a fixed distance after which you would place the buckets to carry up the ice.

In regards to the story about the weld length, that is the process working as intended. As a constructor you don't just decide that something can be a different dimension. And as a engineer you don't just stand "right there" saying "That's no problem". That is how people get killed.
