The proper way to select linear vs switched is really a flow chart of some applications require super low analog noise or low quiescent current and cannot tolerate a switcher solution. The next step is a complete system analysis including power/battery budget AND thermal for both solutions then pick the overall system level winner. No point in spending dollars of switcher components to save fractions of a penny of battery energy.

Another interesting point is its "generally" easier to buy/build constant current linear sources than constant current switching sources. Plenty of sensor applications where you want to mostly just limit to 4-20 mA or similar.

Final point to make is "generally" with massive hand waving and isolated exceptions, linear sources are harder to destroy via inductive loads and oscillating loads and ESD / EMI impacts.

I know a surprisingly nontrivial number of people who needed an SUV, but upsized because of the tax deduction.
How did you get from "taking all the risk" to "taking full responsibility"? Both mean entirely different things and you can easily have one without the other.

i.e. a lead surgeon can and should take "full responsibility" for what happens in the OR, but they obviously neither can nor will (and I also don't think should) shoulder "all the risk" for what happens in the OR (or even most of it).
Ironically, the "Radical" in "TERF" was never intended to be disparaging, but rather as a descriptive label within Radical Feminism. In fact, it could almost be read as begrudging respect from the perspective of non-TE radical feminists. Of course, the term "TERF" has now become so generic that the "R" is almost always a misnomer (and to a certain extent at arguable degrees so is the "F").
The bot greeted me with "sup" and then left the game when I answered and asked it what was up.

I don't find the TFA explanation convincing; it's too abstract.

I like the explanation in terms of predator avoidance behavior. Imagine a primitive fish with eyes that can detect motion. If it sees something moving, usually it wants to get away from that thing. If you see something moving in your left eye, the best way to swim away is to send a signal for a muscle contraction in your right side, which will cause you to curl and swim to the right. So the best wiring is a direct connection from left eye to right side, and right eye to left side. The brain is built up starting from that kind of connection.

I find that it’s difficult to change anyone’s mind on this subject, but the issues I often see are:

1. Overestimating the predictability of the costs of owning a home. As a renter, I know exactly what I will pay for the next year. A homeowner doesn’t have that same knowledge.

2. Comparing rent to mortgage for equivalent properties. Yes, renting the same property will generally compare unfavorably to purchasing it. But compare a 2-bedroom apartment to a 4-bedroom home and the apartment becomes much more competitive financially. However then it comes down to personal preference for the place you want to live, not a rational cost analysis.

3. Underestimating the stress of owning a home and overestimating the stress of renting - but this is also mostly a personal and perspective thing.
I've been using TeX for a long while, and one thing which has frequently struck me is that documents are fundamentally a key-value/markup-content pair and it really should be much easier to to markup and tag documents, and then once they are tagged, changing the appearance should be as simple as swapping out a .css file (which can be achieved in TeX, but requires a bit of effort, though newer documentclasses such as memoir make this much easier), but there doesn't seem to be any sort of effort to stuff a document into a database, re-work it, then get a finished product out.

Jupyter Notebooks seem a step in the right direction, but there's no provision for the appearance AFAIK.

> By manipulating lawn mowing frequency, we established that lawns with the three-week mowing treatment had significantly greater floral abundance than the one or two-week treatments, and that the two-week mowing regime supported the highest bee abundance yet the lowest bee richness and evenness (Fig. 2; Fig. 4b, c, d).

So mow every two weeks and you’ll support the bees.

This is a misleading analogy because Bob "reads the transcript"; we generally view "reading" as separate from our conscious narrative. However, consider the alternate scenario where Bob "replays the stream of consciousness" from Alice. In that case, we may argue that Bob has conscious continuity from Alice.

The argument would then be that the context window is functionally closer to "replaying a stream of consciousness" than "reading a transcript".

If we're seeking to halt climate change, it seems quite reasonable to look at effective measures for that. If decreasing methane emissions from landfill or farming might contribute, it seems odd to write those things off. This is partly due to the way we silo investment in the west: there isn't an organisation that is a single point of coordination and can make the tradeoffs logically. So for better or worse, we should try to make those tradeoffs wherever we can.

To riff off your programming analogy, climate action is like a program that requires a thousand complicated, interdependent functions to be written for it to do its job. Unfortunately in our analogy, virtually none of them ever speak to one another, so the process will be hard, some people will try to bypass other people's contributions - even if they're better - for want of understanding, and the whole thing will be an organic mess.

The difference is, if the program doesn't do what it says, that's kind of fine. If we don't meet or exceed carbon goals, many people around the world are likely to die.

I think that claim is your bias or just misinformation talking. One reason is that it's a common bias of the right - they say liberals think this way, but I never hear actual liberals saying that. Do you have evidence of it?

No, it isn’t. Let’s start with scoping. Everyone in America is immeasurably better off than the median in some countries. Clearly not what anyone in Zuccotti Park meant.

Are you under the impression it’s not? It would push down inequality to remove student loan and public transport subsidies in cities and cut cheques to the poorest rural Americans. That’s obviously not what was wanted by those protesters.

It's worth pointing out 2 things here:

first this is not about letting johnny-middle-class have an after school job that might go a bit late, it's about migrant labor, agriculture has long had exceptions to labor laws to let children work in the fields and this is about letting other industries in on that.

second this is prelude to cutting any sort of welfare /medicaid* /child-credits because the children can now be "expected" to work (and drop out of school helping perpetuate the underclass in the process).

PLEASE READ:

I've read all comments and I realise that I'm presenting this project completely wrong.

It's theoretically impossible to be 100% unbiased, and I'm currently misleading people by stating this across the site.

However, it's not impossible, and quite easy, to be 'the most unbiased' news source.

I believe the project can and will have a net-positive impact, by reducing the effects of sensationalism in the news.

Even if NewsNotFound articles were only 90% neutral, that's 90% BETTER than reading the same story from a sensationalist source.

This project has the potential to provide a platform for readers to digest the news in a 'less biased' way than anywhere else on the internet.

Whether people want this, or prefer to read from biased sources because it's more emotive and relatable, is another issue and I think will stay a matter of preference.

I will update all socials, whitepaper, etc. to reflect this and I apologise for my ignorance initially.

There are a few other fundamental issues that people have pointed out, which I will try to fix over time.

Thank you all for your feedback and insight.

I use GPT-4 pretty consistently(set up a discord bot for myself). What I found myself doing was tending towards the most simple prompt that the LLM would still understand - If I asked a human expert the types of prompts I was giving GPT, I most likely would've gotten a clarifying question rather than an answer like the LLM was giving me, simply because I'm talking in such short and concise sentences.

I think the interesting thing is that the more concise a message is to a fellow human, the more work needs to be done by the other party in order to actually decode my message, even if it is ultimately understandable. Whereas with LLMs, shorter token length doesn't really matter: matrices of the same size are being multiplied anyways.
I worked a part time job after school along with many of my class mates (albeit not in the U.S.). Some did it to support their parents, some for a bit of pocket money. Seemed like an overall worthwhile experience for us.

It can certainly be abused, but perhaps the best remedy for that is not a blanket ban.

I dunno. I started working at 14, cleaning up a beach adjacent to a resort. It was cool and allowed me to earn money for the first time in my life. (Which was promptly spent on 3dfx cards and other bits of computer hardware.) From 15-18, I worked in a book warehouse after school, which was also fun, if much more physically demanding.

Frankly, I've always preferred employment to school. School always felt highly arbitrary and pointless, not to mention extremely boring. Work made more sense -- you're always doing something, not just spinning your wheels -- and the rewards were practically immediate. After a day of school, I felt listless; after a shift at the warehouse, I felt accomplished.

Also, I think that the experience of physical labor should be a component of any boy's education.
I agree it could have been mentioned. Section 0.2, however, part of the short introduction page [0], provides the information:

> Assume for a second that a study of deep relevance to practitioners is replicated, and its conclusions accepted by the research community. It has large sample sizes, a beautiful research plan, a statistically sound system for controlling for various other explanatory factors

As a multi-decade practitioner and manager of software engineering teams, I would certainly be interested in what the best of the empirical research has to say. I think it's important to always remain open to good new ideas wherever they may come from—strong opinions, loosely held, as they say.

That said, I don't believe that statistically significant results can be found that will overturn my own instincts and judgement on any specific project to which I am dedicated. The reason for this is threefold: 1) the universe of software and goals we pursue with is astronomically large 2) competence in software engineering depends on the combination of personal aptitudes and mindsets combined with years of practice and 3) measuring outcomes in software engineering across diverse projects is all but impossible. In other words, you can't equate tools, you can't equate projects, and most of all you can't equate people.

At the end of the day, success in software engineering comes from relentless focus on the specific goals at hand. One must be inherently curious and have a craftsperson's mentality about acquiring technical skill, but never become religious about methodology. This requires continuous first-principles thinking targeted at specifics. At the end of the day, two expert practitioners could propose unorthodox and diametrically opposed approaches to the same problem, and they would still dramatically outperform a lesser skilled journeyman who attempted to follow every best practice.

Empirical studies and the scientific method in general work fantastically well for uncovering the rules and inner workings of the natural world, but software is the creation of logical systems purely by human minds which is an entirely different challenge—there's just not enough evidence to draw on. I suspect results will be at least a couple orders of magnitude softer than sociology, and that probably won't sit well with the type of personality attracted to software in the first place.
Child labor suffers from the same cognitive illusion that child beatings do - namely that the child mind has incredible capacity to normalize practically any treatment. This is part and parcel of the reality-building that occurs at this age. What should happen is that the author matures beyond this mindset and looks back with a healthy dose of adult critique. Sadly, they seem to be maturity plateau.
I looked into this issue with rsqrt (and with rcp as well) between Intel and AMD processors in connection with CERN some years ago (2016). An unpublished report can be found at [1].

TL;DR: The same (very small) executables gave different results when run on Intel and AMD processors because the rsqrt and rcp instructions produced slightly different outputs on the two systems.

Methane - CH4 - degrades to carbon dioxide in the atmosphere. A quick clip, however, it is not: it can take 20 years, during which that single carbon atom yields 20x the global warming potential as part of a methane molecule than it does as part of a carbon dioxide molecule.

The streetcars were equivalent to today’s buses, and were about as fast. Brooklyn and Queens is still only about 4m of the 21m total population of the metro area, so it’s still a small share. Even Nassau to Brooklyn or Queens takes overly long and/or is too expensive.

The West Village is actually not very well connected transport wise, and historically the waterfronts were docks-oriented. Downtown is the historic core where pre-bridges, all the ferries went, and where many bridges still exist. Midtown is the location of the rail terminals, so a suburbanite can walk to their job without having to pay a second fare. (IIRC Grand Central is where it is because at some point the city banned surface-level steam trains below.)
