I hope you can "infect" others with this kind of view, so that more people adopt it.

My CV currently also includes a link to my repositories and a page briefly describing some projects that got anywhere. Far from all of my 100 or so personal free time projects get finished, but some do, and those are described and linked in my CV and on my website.

At least I do get interviews, which must mean at least something, and sometimes it's just the role that is not fitting. Often it is their tech stack and they do not believe in engineers learning things on the job, looking for a perfect match. Sometimes it was some test that they do, that presumes some knowledge about some library or that is some specific leetcode thingy, that I wouldn't code that way anyway, if I had the choice.

It's a pretty common thing that replanted forests turn into monocultures that don't have a lot of value for biodiversity. This then leads to all sorts of problems that healthy diverse forests don't have. I don't know if that's the case with the Appalachian forests but this is depressingly common. That being said, there are good steps being taken, e.g. the rewilding projects by mossy earth.

To pretend that the US "green party" has anything to do whatsoever with the environment is beyond naive, it's completely disconnected from reality.

Neither their policies nor their electorate support the idea that people like Jill Stein are in any way looked at as authorities in any "green" subject.

I don't think that someone that had national relevance for roughly half an election cycle, and who got less than half of one percent of the vote (at the peak of her popularity) has had any influence shaping nuclear opinions.

She's not even on record stating her position, that's how utterly unimportant this issue to Putin / Russia.

I'm not even sure how you think Russia would benefit from less nuclear power plants an entire continent away

We also have one at NC State, still there AFAIK. I thought it made sense though given our nuclear engineering program.

I looked it up and apparently we've had 3 or 4 different reactors on campus over the years, first one in 1950: https://nrp.ne.ncsu.edu/about/history/

I'd wager that even most NC State students don't know that it's there though.

It was a consideration. This is why M-Code exists - so be spoof resistant. And jamming is just a fact of life, which is why the vast majority of US military GPS guided munitions are actually GPS/INS guided munitions. They are all capable of falling back to inertial navigation, with some degradation in performance.

USG is in this position for a few reasons:

* It is actually technologically difficult to create GPS equivalent INS (or similar system). Everyone is pursuing this, not just USG/DOD. The Chinese are too for sure.

* It is true that the DoD became somewhat over reliant on GPS from a training and doctrine perspective. While they continued to develop and buy systems and munitions with INS backup, you can't operate with near total air/space/cyber dominance for ~2 decades without it somehow effecting your culture

* The war in Ukraine has been a catalyst for all sorts of technological changes, both in the West, but all across the world.

$35 for 6 meals for two people at McDonalds? What?

Where I live, one meal at McDonalds is about $12. So 6 * 2 * 12 = $144. Not that much of a difference.

Also, if you aimed for 2200 calories per person per day with that $170, then it isn't really fair comparing to a single McDonald's meal, is it? It sounds like buying whole foods is cheaper.

This isn't entirely true.

It's Atmel that derives massive benefit from GCC, or whoever implemented AVR backend for GCC.

Arduino doesn't - strictly speaking - depend on GCC, it could (and does) use any toolchain that is supplied by MCU vendor.

And it just happens so that many MCU vendors do often use GCC as part of their toolchain. Arduino just bundles that with vendor supplied tools for flashing, etc, like avrdude.

Which is to say - it's the MCU vendors that derive the main benefit from GCC.

Arduino will just happily use whatever toolchain MCU vendors provide.

> When governments do try to push and make it law to have X amount of bushes and unfarmed land in a way that makes sense for wildlife to thrive you instantly get angry farmers on your roads, lose their votes and get publicly accused to starve the nation.

The problem is... farmers are a pretty split bunch. On the one side you have the last few remaining small holdouts trying to make ends meet with a few dozen cows or so, they already get swamped in ever increasing bureaucracy, and on the other side you got the megafarms who not only have the benefits of scale available to them (in anywhere from machines to sheer purchase power for feedstock) but also got dedicated full time employees just taking care about getting government handouts.

Of course the small ones get up in arms whenever anything changes, they don't have the capacity and resiliency left anymore.

I'm sure this site works quite differently from what you say. There's no paid team of moderators flicking stories and comments off the site because management doesn't like them.

There's dang who I've seen edit headlines to match the site rules. Then there's the army of users upvoting and flagging stories, voting (up and down) and flagging comments. If you have some data to backup your sentiments, please do share it - we'd certainly like to evaluate it.
Ask HN: How to start doing LinkedIn outreach to validate SaaS ideas?
by yoouareperfect | 2025-11-22 16:47:08+00:00
As the title says I want to follow the advice of talking to potential customers to see if there's a market and to better understand their needs.

I would like to know which specific steps should one take in the actual sending of a linkedin message.

1) Do you advice just searching in linkedin sales navigator for the persona? Or would you advice using a specific tool for the prospecting? (please don't sell me snake oil, I just want to start and get at least 10 conversations)

2) Do you connect first? Send a "special message"? Or just a regular message (I have literally no idea of how the dynamics of linkedin work and what are the best practices)

So there's that, I've read founding sales, but I believe email outreach is very hard and reply rates are abysmal, so maybe linkedin outreach is better. But the book doesn't go into detail on how to do that.

> You can still find citations of those papers to this day.

That's not what I contested. What fraction of people who use differentials in their published work still cite Newton or Leibnitz was the point. You can count number of such citations in last 10 years of say neural nets literature, or applied maths literature and report. Thats plenty of use.

Citations to their differential calculus that are still made are mostly in the context of history of math.

Seems numeracy or comprehension is not your strong point. LOL.

Now I don't doubt it. LOL

I asked our overlord GPT, and it says that people who use “ROTFLOL” are typically at least in their early 40s or older, since “ROTFLOL” originally comes from Usenet in the 90s and actual 12-year-olds use new acronyms and avoid old ones like “ROTFLOL.” So I was mistaken, and you are just an adult making childish comments on Hacker News to people you disagree with. Congrats.

> I reframed it from "lack of focus" to "poor control over what I focus on".

That's exactly it, and why I prefer it be called an executive function disorder rather than any kind of focus disorder.

I can focus just fine. Too well, actually, to the detriment of all else, including physical needs like eating and sleeping. But I can't control it. I don't get to choose when I'm productive or when I'm not, let alone what I actually focus or work on. I could go weeks at a time where absolutely nothing is interesting enough, everything is painfully boring, and I'm so task paralyzed I just can't do anything. Likewise, I might give into a project for 48 hours straight non stop.

It's amazing I have a job at all, to be honest. I am also autistic, and it is a special kind of hell at times.

Speculation is a legitimate market activity. People make predictions about what will be valuable in the future and marshall those resources toward the most valuable future use. If speculators are wrong, they lose money. There's no free lunch here like you make it sound.

>The correct solution to this is a land value tax, which if implemented correctly, should drive down the price of land down to zero

We have prices to help decide what is the most valuable use of a resource. Trying to implement a bunch of policy to cancel out price signals will lead to all kinds of dysfunctional situations.

Fixed percentage property tax based on market data and legitimate appraisals is the right kind of tax on land (or as correct as it gets; the ideal is that people pay for what public services they use and no more).

>force Jack Ma's family to either commit to actually investing in UK's economy or park their wealth elsewhere.

They are investing in the UK economy by owning land there. A mansion requires maintenance and property tax payments. The UK is not entitled to tell people how they must spend the fruits of their labor. If you'd rather the mansion not go to a foreign rich person, you could ban foreign purchases of mansions. But this would no doubt hurt the people who build and maintain them. Furthermore, Jack Ma probably has limits placed on him by his country. He may only be free to buy a mansion. He will no doubt use it... Leaving a country takes time.

If you want to be mad about land prices, be mad at the infinite deficits and credit bubbles being inflated in the West.

It really does matter because SpaceX has to recover the cost of developing the program. I have no idea what all these test launches cost (where they lose the vehicle) but I wouldn't be surprised if it was in the $300-500M range. Plus development time for all the components, particularly the engines.

Starship is complex. The Raptor engines are complex. There are valid reasons to use Methane instead of Kerosene (ie to avoid coking and the ccost to reuse) but now you need two chilled propellants with everything that entails.

You need to do a lot of launches to become human-rated (like Falcon 9 / Crew Dragon is now). In-orbit refueling is going to take a lot of launches to perfect and prove and it's going to have fairly limited applications to boot.

Plus the entire program is a massive opportunity cost. SpaceX is in their Boeing 747 era now. The 747 was such a massive profit center for Boeing for decades, particularly when the program was paid for so it didn't need to be recovered on each plane delivered.

Ultimately that ends. Engines are so reliable that they don't make 4 engine commercial planes anymore. I read it's likely that the engine will never have to be replaced for the entire life of the plane, which is a vastly different situation to 50-60 years ago when the 747 was first developed.

The Falcon 9 is currently the most successful launch system ever made and it is a cash cow. But if SpaceX spends a decade or more delivering Starship and recovering the program cost, that's a long time for somebody else to come along with an even cheaper platform in the same class as Falcon 9.

It works just like a nuclear reactor. Neutron hit U atoms, those split and emit more neutrons in a cascade. The configuration is set up to not be self sustaining. It’s a matter of geometry, enrichment level and such. Therefore it needs a source of neutrons. Cf-252 is such source. It fires neutrons constantly but has a relatively short half life (you have to replenish it yearly or so).

Yes, I can live with it, but I think the standards have gone down. It also seems to me that you basically consider that change irrelevant. We can surely disagree on that.

As for the Greek philosophers, I feel you are being too dismissive saying that they imagined us being more stupid. First, it was mostly about Socrates and second, his position was a bit more nuanced than how you present it. He was concerned about education becoming impersonal, which definitely has some downsides (until today, we haven't discovered any educational mode more efficient than 1:1 tutoring, at least from the student's individual point of view; the economic dimension, of course, differs). Second, he believed that our memory capabilities would go down, which they probably did. We don't have much contact with purely oral cultures now, but the little we do, show that pre-literate people were indeed better at remembering their collective past, including their culture, in the sense of "actually having it in their own heads" instead of "hearing about it once in the class and then promptly forgetting what they heard".

How many people today can recite a thousand songs from memory? Not that long ago, people like that would exist and keep ancient songs alive.

Today I hear Ed Sheeran ten times a day (ugh), but I wouldn't be able to recollect the lyrics even if threatened with an execution.

That is certainly one way of being stupider than before. Yes, it is compensated by other improvements, no doubt about that.

I was incredibly excited when they announced the chip alongside all kinds of promises regarding Linux support, so I pre-ordered a laptop with the intention of installing Linux later on. When reports came out that single core performance could not even match an old iPhone, alongside WSL troubles and disappointing battery life, I sent it back on arrival.

Instead I paid the premium for a nicely specced Macbook Pro, which is honestly everything I wanted, safe for Linux support. At least it's proper Unix, so I don't notice much difference in my terminal.

Really rich people do if there is a very lopsided tax directed at them personally, like Bezos going to Florida. Switzerland cantons are filled with the very rich who negotiate tax deals with cantons directly. If you edge taxes up overtime or create a broad tax, it isn’t a problem. If you create a wealth tax with a huge deductible specifically targeted at billionaires, they are going to get around that one way or the other.

That article you linked is really bait and switch. No, they won’t leave if you raise taxes, yes, they will leave if you raise taxes just on them (and yes, a $500k deductible on capital gains isn’t going to bother anyone who isn’t a billionaire like Bezos). Also, a wealth tax simply isn’t going to happen at the state level because it would require a liquidation of assets to implement.

> but you're not always in control of where it swivels to.

If we're going with that metaphor, I'd phrase it more in terms of that mount being prone to jamming. My attention doesn't go to completely random places, it only goes to places I want it to, but then gets stuck on things that wouldn't hold the attention of a neurotypical person.

> What fraction of people who use differentials in their published work still cite Newton or Leibnitz was the point

Those papers were written in the 1600s. "The character of physical law", the essay you're ripping off, was written in 1964. 100% papers from the 1960s are cited every single time the techniques are used.

You are as tedious as the original refrain I was complaining about (which is not at all ironic). What's most tedious is you're not actually a mathematician but presume to speak for them.

The entire working mechanism of climate change is increased water in the atmosphere. That's why it's getting warmer. CO2 and other gases only accelerate that process a little bit (but as we're at the end of the warming cycle, "a little bit" should be interpreted as accelerating warming by a little bit, if you count the number of years it brings warming forward, that's a lot. Probably a millennium, maybe more). Obviously it also makes things warmer and generally wetter, thereby making very large areas livable that weren't livable before.

The entire inside of India used to be desert. That desert did not just reduce in size, it split in three pieces and two of them shrunk to zero, and even the third is turning green. The Sahara too is less than half the size it used to be.

https://theweek.com/environment/sahara-desert-turning-green

Also, large regions closer to the poles are becoming warmer ... and that means livable.

And yes, elsewhere deserts are becoming worse, for instance in Spain.

It doesn't really matter though, as humans are not exactly short on space, and this means we'll need to move large populations in the next century.

>You're meant to raise the clutch to the biting point and apply some accelerator and release the handbrake when you are confident that the engine will prevent the car from moving backwards.

You sit there with the gearbox in neutral and your left foot off the clutch (or in gear and on the clutch if green light imminent) with your right foot on the brake.

In gear, clutch to biting point (which will prevent rolling backward), right foot off the brake and then gradually on the accelerator while you let off the clutch pedal with your left foot.

The handbrake literally never enters into it, and the vehicle never rolls back.

> My ADHD always feels the worse when I realize that I have to abide by _insert_arbitrary_deadline_here.

Similar here. For me, if I'm given some arbitrary deadline in the future, it almost guarantees I'm not going to do the thing until the day before, or depending on the task, hours before it's due.

"Hey webguy, we need this report by the end of next week" means I'm not doing it until Friday afternoon, and I have no control over it. Doesn't matter if I try to work on it earlier, just won't happen.

It's having an interest based nervous system. We crave novelty, urgency, interest, and challenge to do anything.

This was also my experience. I found it bizarre that my son was being diagnosed with ADHD when I knew perfectly well how much he focused on his projects. When my sister (who learned about it when HER son was diagnosed) explained why hyperfocus was a diagnostic characteristic, it suddenly made sense.

It is also worth noting that I have encountered an effective therapy for ADHD, which also works miracles for many with autism. It is available at https://thecraigschool.org/. Unfortunately their therapy only works in prepubescent children. That's because it requires the child to make a strong 2 year emotional commitment, but nobody is ready emotionally to predict how they will change after puberty hits.

Still the fundamental principle of the therapy is generally applicable and interesting. It is to condition to child to the idea that, "Every should must come reinforced by a want." This emotional reinforcement results in getting the most possible out of their executive control. With the result that the child becomes able to task switch away from, then back to, hyperfocus.

It is worth anecdotally noting that I've known a couple of people without ADHD who conditioned themselves to the same idea. They reported that they have both the ability to engage with hyperfocus, and to task switch in and out of that state. If we as a society focused on instilling "shoulds" with mostly positive reinforcement, this would be more common. So what brings people with ADHD and autism up to normal executive control, could bring normal people up to superior executive control.

If I was starting over as a parent (not that I want to, I'm done with that part of life!), I would definitely use this idea to inform my parenting.

Might be interesting to know that this is one of the biggest news sites in germany and it's also illegal per https://www.edpb.europa.eu/news/news/2024/edpb-consent-or-pa...

Basically any time you search for information in german, you get this "start an indefinite subscription to open this page" or "confirm that your consent to tracking is freely given" model, which I find highly ironic given that germany is one of the main forces in european lawmaking but then doesn't actually want to comply

I went through this rabbit hole. I liked Mint (I know it wasn't private, but I liked it), I tried Personal Capital / Empower because I had a retirement account with them, I tried Monarch. But none of them had the one killer feature I needed — my wife and I both have individual accounts and we also have a joint account for household expenses. I want to track all of those separately.

The I found Tiller[0]. I've been really happy with it so far.

It basically syncs your transactions to a Google sheet you own. It comes with some basic things like budget and auto categorization based on fuzzy string matching, but because it's Google sheets you can play with it and do whatever you want with it.

But the nice thing is that you can dictate which accounts go into which sheet. So I have two sheets — one for household accounts and one for personal. And I don't need a separate subscription, which would have been required if I used any other service I had looked at. I can't remember exactly how much the subscription was, but I don't remember it being unfair.

> We find testing and evals to be the hardest problem here. This is not entirely surprising, but the agentic nature makes it even harder. Unlike prompts, you cannot just do the evals in some external system because there’s too much you need to feed into it. This means you want to do evals based on observability data or instrumenting your actual test runs. So far none of the solutions we have tried have convinced us that they found the right approach here.

I'm curious about the solutions the op has tried so far here.

What is this, a game of risk? Ignoring the multitude of issues with a Russia+US alliance (I don't think current leadership would ever trust each other), China would absolutely not be okay with the US on its doorstep.

Russia and China aren't exactly good friends, but this is a "the enemy of my enemy is my friend" situation. The US is not popular with either of them.
