> Please don’t project.... This kind of language is why these threads get flagged.

As the person who you responded to noted, you don't know why other people flagged a thread. None of us do. That you believe it's due to tribal battles is your own projection.

What's not a projection is that many people chose to have a discussion on a topic despite the flag, and that's interesting, so maybe worth discussing.

Most definitely different types of particles cause different levels of harm. (Extreme example: asbestos.) However, we don't really have good data to quantify this. It intuitive from evolutionary perspective that "natural" sources would be less harmful since we've been breathing sea spray and dust for millions of years. Yet, smoke from wood fires is clearly still extremely harmful. So... my instinct is that the harm is probably less, but I find it very hard to be confident that any particular source is totally safe.

There's the assumption, at least by me in the past, that every image ever taken by any telescope has been poured over that nothing new could be found by someone like me looking at it. It wasn't until I realized that most images are looked at by the people capturing the image while they look at the image for the one thing they were trying to study. In a Hubble/JWST type image, that point of interest might be < 10% of the captured data. (Think of all of those images of new discoveries that have been so zoomed in that it's nothing but a bunch of pixels) Once they finish with it, it just becomes part of the archive. There have been lots of discoveries of people combing over the archives to find things in existing data without ever needing any 'scope time of their own.

Advantech OSB will outlast conventional plywood by a mile in the rain. I exposed it, flat (the worst way possible) as subfloor, to rains for 1+ year while building my house with only maybe 1mm of fiber degrading on the surface a few places. Many modern OSBs use hydrophobic glues impermeable to water.
Show HN: Largest Open Source MCP Repo (280)
by ashrafsam | 2025-04-02 14:11:22+00:00
Ash here, founder of Activepieces (open source automation). 2 years ago, we launched Activepieces as the open source Zapier (https://news.ycombinator.com/item?id=34723989). Ever since, we grew total integrations (pieces) to 280 of which 60% were built by our community!

Now with the growing popularity of MCP, we built tools around these to turn them into MCP servers. So now every open source integration on Activepieces is an MCP, and we like to think it’s the largest open source MCP repo so far (MIT licensed).

With these tools, you can:

- Self host the MCP server or use our cloud for free.

- Connect any of the 280 tools in your MCP server.

- Provide the server to an MCP client (like Claude Desktop, Cursor or Windsurf).

- Ask the LLM to take actions!

For example, you can ask the LLM to:

- Add meetings to your calendar.

- Check your tasks on Jira.

- Post a tweet for you.

In the next few weeks, we’ll make the automation flows available as MCPs too. and we will make MCPs usable by LLMs inside our flows.

- List of MCPs and instructions: https://www.activepieces.com/mcp

- GitHub repo: https://github.com/activepieces/activepieces

My rec sailing team uses an e-ink chart plotter. I like it more than anything else I've used for that purpose, it really is a great fit. Unfortunately they're like $800 and I have no idea if it could be adapted to a general purpose gps. I have long suspected it just runs android but never really looked into it and don't know how much that would help anyway. https://www.maptattoo.com

If by "logical" you mean "practical" then the reason is that the study which cost a lot of money to do, the constituent studies that generate data, are more likely to get a press release, and that is how non-specialists learn about new studies. Logically, from the perspective of the university, being able to point out the result of spending a lot of money to contribute to human knowledge is important, so they publicize these expensive studies. The metaanalysis is cheap, and takes a few people's time for doing the analysis, no new expensive data involved.

I don’t think that fake deadlines are better than real ones. Fake deadlines can provide value but they indicate the environment is deficient in other ways: some sort of trust is lacking. The fake deadline is a bandaid on top of that.

I think you can get the same benefit as fake deadlines with real deadlines (ones with teeth) and without executing from an initial position of, “someone can’t be trusted so the deadline must be fake.”

While not e-Ink, I had the impression that the Beeline has more outdoors-suitable displays. From the Beeline Moto 2 specs:

"Technology: Ultra bright IPS TFT with anti-reflective and hydrophobic coating"

But e-Ink would be superior for outdoors readability. I was looking for a motorcycle navigator when I found the OP article.

Search engine crawlers, aggregators, vertical markets crawlers and so on may give you visibility, are not so much, and are usually well-behaved (i.e. respect robots.txt, announce themselves with a consistent user agent, etc).

Security/vulnerability scans doesn't ask too much pages, at least existing ones, and usually come from few IPs from time to time.

But AI crawlers could be really a lot, try to get all your pages, and not always are respectful about robots.txt or your performance, u. And don't give you anything back. There may be exceptions, but the few you notice ends having a negative impact.

I sell and run union electrical work for a living in the United States.

Residential power in the US is 120/240V single-phase (split phase). Utility distribution is three-phase and virtually every commercial and industrial electrical service is three-phase, with the rest being 120/240V single-phase.

> In some cases they even try to compensate by doing it themselves (especially first-time managers).

It’s ok to ask people to work a bit harder. It’s your job to find the right balance.

It’s an error to work as hard as you ask your subordinates to, in service of an arbitrary deadline you cooked up just to put pressure on them?

> I always feel responsible for delivering on time, so I used to work my ass off (weekends and nights included) just to meet a random date. […]

Once I became a manager, I finally saw why they were needed, but felt guilty about using them.

Perhaps it’s worth listening to that twinge of guilt. There’s nothing virtuous about tricking or cajoling people into that kind of a cadence—especially just as routine way of running your shop. Emergencies, maybe—real deadlines, maybe—but run a respectful shop and I bet people will step up when times call for it.

Deadlines aren't for tech teams. Their for anal upper management more concerned with quarterly financials than deliverables and stake holders who fundamentally do not understand how tech works.

When someone asks for a deadline, the answer should be "it gets done when it gets done."

But if you are a technical who is being asked, the correct answer is the real estimated timeline + at least 2 weeks, depending on complexity.

Wasn't agile created to solve this BS? Why is this still even a discussion? I have got better things to do than waste time answering stupid questions form stupid managers.
by tikhonj | 2025-04-02 14:14:22+00:00
The main point of this article is that you need fake deadlines so that people don't take too much time working on things—and that's simply not true. The best teams I worked on did not have fake deadlines but still moved fast (noticeably faster than peer teams in the same org) because we felt real ownership over what we were doing; intrinsic motivation is far stronger than extrinsic motivation.

If you actually trust the people doing the work—and if you fervently believe in Parkinson's Law, you don't—you wouldn't reach for fake deadlines, you would just ask people for what you need, and give them enough context to persuade them.

You can just go and ask: "how can we get something useful out faster so that downstream team X can start experimenting with our system?". As long as you trust the team and you've managed to get the team to trust you, why wouldn't they try to do that?

I mean, there might be some real reasons not to hurry in any specific situation, but if there are you would talk about it. And maybe those reasons are strong enough that you shouldn't be trying to get something out faster just then! Or maybe there's a mismatch in your understanding of the situation that needs to be sorted out. Or maybe the team really does need to change their approach to get something out faster, even if there are real costs to doing that. Getting to that conclusion bottom-up with the team is going to be way more productive, less stressful and less trust-destroying than imposing and then missing fake deadlines.

> It’s completely ok to not have anything external happen when the deadline arrives! That doesn’t mean the effort to meet it was wasted. You built trust with the rest of the organization and you freed yourself to work on other things.

Does it usually motivate people to work hard, when they know the outcome of the crunch is "more trust with the rest of the organization" and "now I can work on other things"? Sounds pretty dystopian to me, and not all what motives me to do good work.

I think if someone pushed me to deliver something urgently to hit a deadline, I'd expect that deadline to have some sort of meaning, not just "now others trust you more". If no one actually needed that thing at that date, why was I being rushed to finish that specific thing for that specific date?

On the figures in the article: 62,000 seizures, half under $8800, total of $2.5 billion. Doing some rough calculations, assume 31,000 seizures of $8000 and that’s a total of $248 million. That leaves the other half of the seizures to make up the remaining $2.25 billion, or an average of more than $70,000 per seizure.

Is it typical in the US to carry cash in the tens of thousands of dollars? While I understand some people are unbanked, surely it is possible to open a bank account if you have tens of thousands to deposit. Leaving aside whether it is legal to seize the money or whether it is ethical to do so, is there a good reason why you would choose to walk around with, say, $100,000 in cash instead of a bank cheque or a a plastic card?

> No one bullies harder than the nerds around here. Such a hateful bunch of ignorant fools.

I’m not sure if this is true. We’re all people, and people have tendencies to other others and seek belonging, that can hurt people.

I don’t think this community is particularly bad. And I’ll add that it’s probably the most “civil” of all the sites I’ve used over the years (usenet, slashdot, fark, lobste.rs, kuroshin, plastic, digg, reddit, netslaves, 4chan).

Ignorant fools, perhaps. But bullies, I don’t think so.

The argument for "vibe coding" (or generally heavy-use of AI coding) is always along the lines of 1. Vibe coding is much more efficient than regular coding 2. If you don't learn vibe coding you will fall behind

I see lots of arguing over point 1. but I think we can reason about 2. such that it makes the veracity of 1. irrelevant.

There is literally no skill you have to learn NOW (meaning today, this week, this year) that will ruin your career if you don't learn it. There are still very productive and well compensated people writing using editors and other tooling created in the 20th century.

Equally, your boss isn't going to come in to work tomorrow and say "you aren't already a vibe coder?! We expect you to be even though this is the first time I am mentioning it. You're FIRED!"

So if you want to learn "vibe coding", go ahead, but don't feel some great existential anxiety over it. People saying you will "fall behind" are just creating clickbait nonsense.

The proliferation of crawlers is part of the problem. They're also more aggressive and poorly behaved than typical search engines. Some issues:

- They request every resource, vastly increasing costs compared to a normal crawler.

- They not only don't respect robots.txt; they use it as an explicit source of more links to mine.

- They request resources frequently (many reports of 100x per day), sometimes from bugs and sometimes to ensure they have the latest copy.

- There's no rate limiting. It's trivial to create a crawler architecture where the crawler operates at full tilt, spread across millions of pages and respecting each site, but they don't bother, so even if everything else were fine it starts looking like a DOS attack.

- They intentionally use pools of IPs and other resources to obfuscate their identities and make themselves harder to block.

How much of that is "baby's first crawler" not being written very well, and how much is actual malice? Who knows, but the net effect is huge jumps in costs to support the AI wave.

> sentiment is factual

the sentiment might exist, but that doesn't mean it's based on facts

that discussion you linked to can be broken down into:

- people upset because they thought Wikipedia was almost bankrupt and it turns out its not (though Wikipedia never claimed to be in its fund-raising)

- people upset because they see too many requests for donations

- people upset because Wikimedia execs are getting "high" salaries (though they are much _much_ lower than at private co's)

- people upset because they think Wikipedia spreads "left-wing ideologies"

None of this has anything to do with "corruption".

SoC on N4P.

The CPU consists of 1x Cortex-X4 prime core clocked at up to 3.2GHz, 3x Cortex-A720 cores at 3.0GHz, 2x Cortex-A720 cores at 2.8GHz, and 2x Cortex-A720 cores at 2.0GHz. The new chip is 31% faster than last year’s Snapdragon 8s Gen 3 while drawing 39% less power.

New Adreno 825 GPU, which Qualcomm is advertising to offer a 49% improvement on the graphics side compared to the Snapdragon 8s Gen 3.

Snapdragon X75 5G modem, Wi-Fi 7 and Bluetooth 6.0 connectivity.

This surely sounds like a perfect chip in so many ways. Roughly Apple A15 in Single Thread which is good enough. If this was on N3P it would have rivalled A18 in Single Thread.

And I expect this to be cheaper than the Elite. This should push the average Android performance up.

Now waiting for Mediatek to respond.

I've had the exact same experience, it took a while for creatine to start truly having an effect but I could see the extra water retention in the mirror and feel it in the gym.

I think this study may have been too flawed to reach a strong conclusion.

> After the 7-day wash-in, both groups followed the same RT program that comprising 3 full-body sessions a week for 12 weeks...

> For all assessments, participants reported to the Exercise Physiology Research Lab (UNSW Sydney, Australia) at the same time of day between 8 h and 9 h following an 8-h fast which included refraining from all liquids except water...

So extra stamina isn't rewarded due to the same workout plan and conventional wisdom on insulin and its effect on muscle absorption of creatine is completely ignored due to the 8 hour fasting period.

This study seems to paint creatine as a magic muscle bullet where it seems to be common knowledge in the fitness community that it aids recovery and stamina. I have my doubts.

The incompetence hypothesis makes sense (it is often a good explanation). Web indexers like Google had decades to get really good at this, including hoards of people who work on crawlers full time. AI companies are often very young, execute with small teams, and don't consider web indexing their main activity, just something they do in support of pre-training (or maybe serving web results).

Uh, that's just wrong. You may have contractual deadlines for delivery that are real and meaningful, for example.

A refusal to engage in meaningful discussions about forecasts does not free you from the obligation to meet one. You must might not like the one you get imposed on you if you refuse.

A moving story, but also very interesting in many ways. It makes me think about Edgar Morin and his thesis on complexity, how current science has become so specialized that it has great difficulty in looking at the whole. In this case, these are very similar problems, but still. Of course, it is also worth mentioning that the potential of AI for research is enormous.

If (as in this study) the athletes stuck to their same level of resistance training (ie weight + reps) I would expect the study to hold with the exception of finely measured muscle teardown.

As other commenters have posted, the popular suggested use of creatine use it to either increase resistance (extra reps at a greater weight) or decrease downtime (lack of atp / lactic acid buildup that breaks down muscles)

> it's not really a bus it's just addressed multiple chips on the same wafer

I'm electronics engineer, and even have once baked one chip layer on semiconductor practice, so I'm aware about technologies.

As I said before on Sinclair, few companies tried to make new on semiconductor market, and even some have success.

RAM manufacturers for a long time using approach of make multi-chip on one wafer - most RAM chips actually have 4..6 RAMs in one package, but few of them don't pass tests and disabled by fuses, so appear chips with 2 or 4 RAMs enabled and even with odd number of enabled chips.

Looks like Cerebras use similar to RAM manufacturers approach, just for other niche.

> Is there evidence that left wingers tend to be more as affluent than right wingers? Genuinely asking.

Yes, just read the articles about the Democrats losing the working class. There's lot of evidence and analysis in them on your very question.

IIRC, the Democrats have been tuning more and more into educated, affluent people, and those people have been tuning into liberal positions on culture war issues. These are the people who inhabit the influential positions of the party, and they set the agenda to resonate with themselves (e.g. student loan forgiveness). That caused them to lose sight of the traditional working class, and thus shed working class support.

I cook every day and love trying new things. There's no reason to pick just one, but if I had to, Chef John is my go-to.

Is it just me or is there a huge difference between the success thought leaders are having with AI coding and the way average people are. The idea that cursor could write 35,000 lines of working code is just bananas to me. Maybe I should try the Google model but he also mentions Claude 3.5 and Claude 3.5 and 3.7 have been downright awful. I’ve literally had these tools recommend dozens of changes to undo specific things I asked them to do.

I want to be a believer, I am all in on vibe coding spending hours a day trying to get it to work, and have experienced nothing but frustration. I’m starting to think I’m just an idiot that’s too stupid to use these tools. But isn’t that the sales pitch? That any idiot could do it!?

>I'd expect that deadline to have some sort of meaning, not just "now others trust you more".

Every place of work where I saw that being pushed and accepted once, then crunch just became the new norm over time, 100% of the time.

Developers accepting the crunch to please management, signals to management that they can outsource the externalities and consequences of their bad estimations and planning onto the developers without consequences while they collect the bonuses for the deadlines being met.

While on the other hand, pushing against the crunch when/if you can, forces management to be more careful and realistic with expectations, basically to do their fucking job right.
