You want to wire all the solar cells (72-122 solar cells per solar panel) in parallel, even the different layers of a cell you should wire in parallel. The same goes for batteries.

The reason everyone wires solar panels and batteries in series was that no micro- and nanoinvertors where available or too expensive. That has changed recently, so we now should wire everything in parallel and get 20-50% improvement.
I think the experience on the SWE end of things is a lot different than the SRE end. For instance, I wanted to hire 2 JR/SRE1s last year and my team are all self-taught so we wanted to focus on finding someone early in their career who we could actually teach good practices to - this is something that sysadmins/etc in the mid2000s didn't have at all. We were in that "Need 3-5 yoe" but nobody would hire you to get it and you better know what you were doing when you showed up.

We decided to bring on a current customer support agent who had no prior server/aws experience, and someone who came from client-side IT, which I remember being stuck in and DYING to try to figure out how to move up from. I've never heard of a SWE team bringing on someone who didn't already know a language. We expected to teach Terraform, go, etc.

I can't even remember what my team went to school for I don't even look at that part of someones resume beyond a curious glance.

Because the Infra/Ops people like us come from a less standardized CS background, you know, a LOT of us are dropouts and the rebellious punk youth types with face tats (/s) I think we tend to empathize a lot more for unique backgrounds over Stanford and what not.

We were treated like trash and almost everything was trial-by-fire, as in literally firing you if some big customers website went down. I got fired once for taking down a Six Flags database when I had 2 years of experience and NO other windows syseng at my company.

BUT! Now that people like us who did potentially get treated like absolute trash by NOCs or managers or whomever else stifled us in our climb up that hellish aldder are in charge we can break down the gates.

None of my job ads mention a college degree or anything of that nature and a bunch of my project friends in some major github projecfts do the same at their corps.

I HOPE things loosen up more on the SWE end of things. As an example, I hated my experience interviewing at Google.
Over the past few years, the highest grossing games are freemium pay to win games, like Star Trek Fleet Comman. While they're available on both android and iOS, the fact that iOS users tend to me more affluent means that the revenue tends to come from in-app purchases on iOS more than android.
It wouldn’t surprise me if Apple Music on iOS was in a similar boat to the Mac version (which is just the crusty old iTunes codebase with a lick of red paint).

It feels very much like it’s still the same old app built for the time when any music you’d be playing was locally downloaded, but with streaming haphazardly retrofitted.

It’s pretty sluggish even with a flawless connection, but if you’re somewhere spotty like on a train it becomes basically unusable. Even for stuff you have downloaded for offline playback, it seems like it will try to stream it instead if there is any network connection at all, regardless of how bad it is.

Steps I've been taking so far -

I'm a self taught swe so I have built all sorts of apps professionally. From social apps to e commerce to b2b saas. I've also done everything from web, mobile, infra, data, etc. I love tech!!

I'm also a big fan of optimizing processes, whether it was in my previous jobs like maintaining an office supply or cleaning. I like to help out my friends on their projects like building physical stuff or volunteering and then finding out their pain points and coming up with a plan and implementing it.

I'd like to build all sorts of businesses. It has been something I've always wanted to do eventually. I think everything is doable, but it needs capital. I want to put everything I've earned into my current business, and see how far I can take it before I try to raise VC (no idea how that works tbh).

I find that people who actually run businesses suffer from technology overwhelming them. They want a solution that works, but are forced to purchase multiple subscriptions and hardware solutions that don't work well. All the tools that do exist out there to solve these problems are really technical. Like think about Notion. Maybe you and I as tech workers can find it easy to use. Try getting an abuela or someone's abba who runs a shop to use it. Impossible. Even I find Notion hard to use at times and I consider myself a geek (definitely not at a Stanford level, but I try on my terms).

So I've got a few pilot customers hopefully who will use my software.

Through my software I hope people can build and sustain all sorts of businesses. Eventually I'd like to take a crack at the enterprise software behemoths. But that's way down the line, right now I'm just an ant :)

In my case I grew up not that well off, and I'm a first gen immigrant. I am trying to become an entrepreneur while balancing a full time swe job. I have no fallback at all, and while I have no family of my own yet, I do have parents who gave me a shot at life in US. I can't just go for broke because they rely on me to some extent. I'd say it isn't difficult, but requires persistence. I'm sure if I had a foothold in this country I'd be quitting my job already and living off my savings, but unfortunately not in this lifetime.

I'm hopeful that this year is a turning point for me. I'm in Bay Area for a while now, and hoping my hard work pays off. No revenue yet but I will get there :)

tldr: the Missouri fired a chaff and the other ships CIWS was all “not in my airspace” and started shooting at it even though the Missouri was behind the target. Interesting, I wonder if the whole battlegroup has synced systems now to avoid such things, e.g. 1) I’m going to launch something, everyone else disregard it as a threat and 2) if a threat has a friendly behind it, don’t shoot it.

Maybe 2) is more of a judgement call since a few bullet holes is probably preferential to the alternative.

> As soon as i read this a beautiful and peaceful life flashed before my eyes.

I lived such a life on my grandparents subsistence farm in early post-communist Romania, where we only bought store made bread and nothing else for months (and even that was optional, but store made bread tasted better than homemade).

I would LOVE to go back in time to that house on a summer night, 0 light pollution, starry night, just the crickets and occasional sound of the hooves of the cows or horse against the stone pavement in their yard when they went for a drink, or the dog being happy you visit him outside when you take a piss.

Or the late evening dinner on the high porch, people across the stone-wall fence returning from the fields in their horse pulled carriages overburdened with hay.
Or the strong sense of community of the people gathered at their out of the gate benches smaltalking in the evening.

Or the rain-invocation rituals that involved splashing the village virgins dressed only in leaves in their late evening procession.
Or the taste of milk straight after being milked out of the cow (I don't know how I never got sick), or the taste of fresh butter, or cheese or whey cheese.

Or fetching sheep milk from the herd manager over the bouncy wire bridge, starry night, accompanied by swarms of fireflies, wind whispering through the alder leaves.

Or the cows opening the iron gate with a thud in the evening when they return with the communal herd.

Or riding the horse without a saddle because my shoeless feet hurt from walking over freshly scythed grasslands.

Or returning with my grandpa late in the night from a long trip up the mountain to his lonely uncle's house. We brought him meaty treats and he showed us the squirrels in his roof attic.

Or to hear my grandparents extraordinary survival stories or stories about supranatural occurences.
> there's another reason for some optimism about a voting-truth connection: wisdom of the crowds. As long as there isn't a strong bias to people's estimate, the average will converge on the truth.

Hmmm ... that doesn't seem to match what actually happens. After false beliefs holding back humanity for its entire history, science came along and produced actual, working, truth. And science is the opposite of what you say: The crowds don't matter, only the facts. Newton was not a crowd, and the crowds didn't produce anything remotely as true and valuable for all those years. The crowds persecuted Galileo (and many others).

"In matters of science, the authority of thousands is not worth the humble reasoning of one single person." - attributed to Galileo

As someone pointed out, I think here on HN, the intuition of the crowds sucks. If it was any good, we'd have had the right physics in 5,000 BCE not starting in the 17th century.

> The argument is: (1) the cost is large -- implementation and maintenance of a complex image codec takes time, and image codecs are high-risk from a security perspective.

If you look at the history of Google employees created the basis for JPEG XL [1], having it included in beta builds of Chrome and then removing it "for reasons", it's pretty obvious it wasn't pulled for technical or security reasons.

Obviously Apple didn't think there were significant security and implementation issues preventing them from enabling JPEG XL on over 2 billion devices.

The Chrome team has proposed a number of web features and APIs that Apple, Mozilla and sometimes Microsoft don't want to implement due to security and privacy reasons. Usually that doesn't stop Chrome from going ahead and shipping them anyway.

> (2) the benefit is relatively small -- it needs to provide a clear advantage over existing alternatives like jpg, png, webp, avif in some significant general use cases.

JPEG XL does provide advantages over existing alternatives—The Case for JPEG XL [2]:

In the past, new image formats have been introduced that brought
improvements in some areas while also introducing regressions in
others. For example, PNG was a great improvement over GIF,
except that it did not support animation. WebP brought
compression improvements over JPEG in the low to medium fidelity
range but at the cost of losing progressive decoding and
high-fidelity 4:4:4 encoding. AVIF improved compression further,
but at the cost of both progressive decoding and deployable
encoders.

We looked at six aspects of JPEG XL where it brings significant
benefits over existing image formats:

* Lossless JPEG recompression (20% on average)

* Progressive decoding

* Lossless compression performance

* Lossy compression performance

* Deployable encoder

* Works across the workflow

Maybe they’re ok getting scammed for $25M now and then I guess.
You don't need to spend $1k on a NAS. Go on eBay and buy an old motherboard with 6 SATA ports and an m.2 slot for the OS. I see one with a CPU for $88 incl. shipping right now. You might be able to do better. Throw it in any case. If you don't have one, buy any ATX tower on eBay for $30. You might even be able to combine the previous two steps. If you don't have enough bays, just leave the tower on its side with the disks floating somewhere. I did that for years when I was a teenager and it's fine. Then you just need a PSU and disks.

Or if you're into nerd stuff like this you might have an old computer that you can reuse and you just need disks.

You also don't need to leave it on 24/7. Around me the bottom tier download for Comcast is 75 Mb/s, which is 5-10x the bit rate of streaming, so after an initial period to get you started and build up a buffer, you should be able to build your collection faster than you can watch it on average while only keeping it on while you watch.
When data journalism goes wrong
It's also worth noting - the concept is bottom-up, practitioner-driven, while the experiments that get at theory of mind are top-down, academic-driven.

Theory of mind would exist even if it stopped showing up in academic papers, only because it makes sense to have a shorthand for "my patient keeps complaining about uncomfortable social situations, and after I dig in, it turns out they were missing important social cues". That was known by therapists long before we started trying to operationalize theory-of-mind issues for experiments.

It's really, really tough to design an experiment for this, because it's not super easy to design a multiple-choice questionnaire that will predict if you'll have difficulty understanding subtle social cues. It's a thing that a face-to-face interview would uncover, but not necessarily someone's written output.

You can also run experiments where an investigator interviews the person and records when they miss a social cue, but even then lots of high-functioning autistic people would be able to pass that even if they genuinely have trouble interpreting social cues on a regular basis.

> Ultimately, if you want to get rid of those, you'd have to rewrite the libc in Rust.

No, you can eliminate these bugs by getting better at writing code. The language is independent from the quality of any given code.

Rust is capable of introducing theses bugs, but the language is more explicit when you do. One languages isn't more secure than another. They each attempt to fill a niche, some trade language usability for correctness, some trade correctness for being easy to use.

No, they found organic fuorine in the products. FTA:

> CR tested products for their total organic fluorine content, which is considered the simplest way to assess a material’s total PFAS content."

Totally different, and so completely misleading that it's mind-boggling. Do you know how many things have organic fluorine that have nothing to do with PFAS? Here:

https://en.wikipedia.org/wiki/Organofluorine_chemistry

They repeatedly say in the article that it's basically impossible to reduce organic fluorine content to zero, because it's everywhere. You cannot leap to the conclusion that "finding organic fluorine" has any relationship to Teflon in food wrapping (especially at the 20ppm threshold they used), and you also can't jump to the conclusion that this means that there's a specific health risk.

They do test for a few specific PFAS compounds "in a subset" of the wrappers later in the article. This is more compelling -- but again, you don't know where it comes from.

The ability to keep running things like Flash is a nice bonus. (I do use flash projector, a standalone Adobe app which loads swf files; I would never run outdated flash in my web browser.)
I'm not sure how the benefit could be considered small, being able to perform lossless compression of JPEGs alone is such a massive benefit. In my testing I do every now and then which consists of ripping thousands of images from various websites (image boards, scraping from websites I visit) I regularly get 20-40% file size savings when transcoding JPEG to JXL. These aren't some small 256x256 icons or cherry picked image sets of 25 pictures people love to test. This is as much as a real world use test one could possibly get for web testing.

Completely ignoring the potential of replacing PNG or WEBP, Completely ignoring actually competing against AVIF. The benefits of JXL when it comes to losslessly saving space for pre-existing images is so massively significant, it's hard to believe that this single feature alone doesn't meet the bar of worth.
I wish PWA advocates were more intellectually honest.

They don't care about the web and what is good for end users i.e. more APIs = less privacy.

They simply want to build apps without Apple's fee and controls.

Thanks, really appreciate the feedback! I thought of the name Grizzly Bulls as kind of catchy since the goal is periodically hedging market downturns and so somewhat oscillating from (grizzly) bearish to bullish in macro outlook, but agree that it definitely does not feel directly connected to algotrading.

Unreliability is relative. Everyone botches this up all the time. The most neurotypical person I ever met literally questioned the whole premise of predicting what other people were thinking and said that most people will just tell you things if you ask.
One of the tradeoffs you make as you move up the ladder is that you increasingly can't be an anonymous person. That may be a good tradeoff or bad depending upon your perspective.
> Even more despised than the Brunch People are the vegetarians. Serious cooks regard these members of the dining public—and their Hezbollah-like splinter faction, the vegans—as enemies of everything that’s good and decent in the human spirit. To live life without veal or chicken stock, fish cheeks, sausages, cheese, or organ meats is treasonous.

Yikes. A comment that was a product of its times, I suppose.

It is worth noting that Anthony Bourdain appeared to have changed his mind about vegetarian food after visiting Punjab, India[1], like so many other Western chefs whose only experience of vegetarian food so far was soggy vegetables, coleslaw, cold French fries, and sub-par pasta.

It helps to have a history of vegetarianism going back nearly four millennia, I suppose.

This struck me as suitable for a legal definition, maybe, if "theory of mind" needed one.

However, I don't know how someone could be diagnosed as "autistic" such that you could say "autistic people don't have a theory of mind." I mean, how did you decide they were "autistic" in the first place?

All you have to do is read some documentation written by a technical person to see that they have no sense of what other people know. Arguing whether that should be called "theory of mind" or if it needs some other name strikes me as just semantics -- useful for a researcher or the DSM, maybe, but of no value to the lay person. For an ordinary person, we can just say, "yeah, they can't put themselves in someone else's place."
