tractor tech is non-trivial, but with more investors open to hard tech, building "open" tractors to compete with "closed" tractors like john deere seems like a potential startup opportunity and could also contribute to future trends like robotic farming.

Rust famously does not do implicit allocation or implicit nontrivial construction. It also famously doesn’t do implicit construction when concrete parameter types don’t match the types in function signatures, which is a common source of side effects (and memory corruption) in C++.

In general, Rust is more implicit than C, but significantly less implicit than C++. Moreover, the ways in which Rust is implicit are more consistent and less likely to introduce bugs.
> you are conflating the abstract algorithm with a narrow implementation

They're literally telling you Git uses a Merkle DAG and they wanted to recreate Git so they used a Merkle DAG. That's not conflating, it's copying.

> you seem to be only loosely familiar with database architecture

Based on what? The only comments GP has made about DBA in this entire HN thread is "this is not MVCC", which is correct.

> I am actually a big fan of people trying unorthodox approaches to databases that have never been tried before

So stop discouraging the neophyte? Sometimes innovation requires the ignorant to figure things out without knowing better, because that way they won't quit before they've begun. Let them figure it out. And if it's not novel, who cares? It doesn't have to be some perfect architectural masterpiece to solve people's problems. If it works well enough just for WordPress blogs, that's pretty great already.
> I just think it's a potentially awkward situation when it comes to something as core as the kernel; which has traditionally only required GCC.

Clang is starting to leapfrog GCC here. IIRC, some features are better supported and/or more advanced on Clang, other features (e.g. LTO) are exclusive to it. Not to mention it's almost a certainty for Clang to land kernel PGO support long before GCC, in fact Google already uses it in production Android kernels.

Anyway, rust or not, linux is being decoupled from GCC.
It is a pet peeve of mine when people offer code samples that require horizontal scrolling even when full-screened on a 1440p monitor (let alone 1080p).

Either don't use arbitrarily size-restricted code blocks, or manually format your code so it's legible in the window size you've chosen.
The Waller guy quoted saying that electronic surveillance requires a warrant is incorrect. You don't have an expectation of privacy from video recording in public spaces, and Washington DC is a one-party consent jurisdiction, where the subject of a video/audio recording is not required to provide consent to being recorded.

Many other claims in the article seem questionable (unsurprising given the source), but this was flat out wrong.
BA.4/BA.5 will soon be dominant in the US. Here’s what that means
I understand the feeling, but that's not possible, and moreover, after reflection, why should it be so?

If government can literally fine/shutdown your business arbitrarily (as they do for lockdowns, permits, etc.), then they should have a voice in the government that could treat them so terribly.

Unless you mean to say that government should be so much smaller that it doesn't impose separate business taxes, import/export controls, require permitting and licensing and follow arbitrary regulations on those businesses, which I could get behind. Ideally, if there's no advantage or penalty to avoid by petitioning government, won't everyone stop paying attention to government? No gaming the game can happen then!

The problem is that we can't have it both ways, can't restrict a group from petitioning and then pose rules they MUST follow, without a say. That's not democracy at all.

Companies are just groups of individuals after all, and should have just as much voice as an activist group does, like ACLU or Americans for Tax Reform or whatever.
What you said is all true, but the Nazi thing is almost certainly propaganda. Putin wants to restore the USSR and his justification for annexing Ukraine has been to question the existence of a separate Ukrainian Culture and State. You only have to go over the stuff he’s talked about since the last invasion; most of it is the reunification nostalgia, very little about defeating “Nazis”.

> would require home built solutions which would always be terrible, less secure,

I disagree. It would be relatively straightforward to build such systems on Linux and open source.

> and more expensive to the tax payer

As a proportion of Italy's GDP, the cost would be negligible, especially given that this is a matter of national security, something governments tend to be keen to spend money on.
I fully agree that this is just one of the many battles in a long war by the elite to erase private ownership completely. People call it a conspiracy theory but the trend is very clear to see, and has been accelerating for the past few decades. Thus it is good to see some opposition showing up.

There have been a few. It often comes down to something that was previously unsound being made an error. There’s been long deprecation periods when this happens.

The fact that it’s hard to even remember that these things have happened is a testament to how rarely it happens and how well the breakage is handled.
Thanks, that's informative. This was meant to clarify the bounds of Zig's design rather than as a research proposal. Otherwise, one might read it as an open invitation to just the sort of demonic meta-thinking that its users abhor.
Either way as the court decided today it applies to all "bearable arms", I guess you can't really bear a hellfire missile, M1-Abrams Tank or an atomic bomb, but I don't see how fully automatic weapons aren't bearable. Viral\chemical weapons seem super bearable, but I bet they would call them something tricky like munitions instead.

Really the law doesn't have much internal consistency. People like to say it's complicated, but I think it's just broken.

Yeah I'm somewhat confused as well. I even somewhat agree that using only vanilla SQL might make it tricky to answer some complex questions (not limited to questions about sequences), but why would that be your goal?

The idea of a DSL to analyse sequences of events is interesting, but I'm not convinced by their examples (I mean if you want the order of events, why store them as columns of booleans saying X happened?). They also claim without proof that tables of events are somehow 'arcane' and hard to deal with, but the examples they give aren't exactly complicated even using just SQL (the best I can give them is that they may not be solvable without writing a query, but a new query language doesn't solve that problem).
I’ve never really understood the concept of an ‘app’, in some projects I’m sure in makes sense but it not being transparent by default in a new project seems silly.

Am I missing something here?
> Putin wants to restore the USSR

The Russian Empire is probably more accurate (he has repeatedly specifically referenced Peter the Great); the USSR he has portrayed as simply a poorly managed intermediate stage of historical Russia.

> Getting "screwed" in academia means getting a B because of a tricky question on a final, or having to publish in a less prestigious journal than you think you deserve.

Actually, getting screwed in academia is:

- Never getting a tenure track position because your advisor has bad mouthed you (common)

- Not getting tenure and never getting another chance at it.

> Getting screwed in industry means you lose your right to an income and might never get it back.

Everyone I know who got fired got another job and bounced back. Lose tenure? You'll only get a second chance if you are particularly good.

Most of the times, in industry, getting screwed just means not getting a promotion.

Abstract:

The metastatic spread of cancer is achieved by the haematogenous dissemination of circulating tumour cells (CTCs). Generally, however, the temporal dynamics that dictate the generation of metastasis-competent CTCs are largely uncharacterized, and it is often assumed that CTCs are constantly shed from growing tumours or are shed as a consequence of mechanical insults1. Here we observe a striking and unexpected pattern of CTC generation dynamics in both patients with breast cancer and mouse models, highlighting that most spontaneous CTC intravasation events occur during sleep. Further, we demonstrate that rest-phase CTCs are highly prone to metastasize, whereas CTCs generated during the active phase are devoid of metastatic ability. Mechanistically, single-cell RNA sequencing analysis of CTCs reveals a marked upregulation of mitotic genes exclusively during the rest phase in both patients and mouse models, enabling metastasis proficiency. Systemically, we find that key circadian rhythm hormones such as melatonin, testosterone and glucocorticoids dictate CTC generation dynamics, and as a consequence, that insulin directly promotes tumour cell proliferation in vivo, yet in a time-dependent manner. Thus, the spontaneous generation of CTCs with a high proclivity to metastasize does not occur continuously, but it is concentrated within the rest phase of the affected individual, providing a new rationale for time-controlled interrogation and treatment of metastasis-prone cancers.
Right, but only regional powers have a real chance of doing that.

Before you have a military industrial complex, you need the industrial complex, or at least the capacity to develop one. Smaller countries with scant resources are vulnerable to sanctions so they generally don’t have this capability. The bigger countries try and get nukes. Who’s left?
You are at much greater immediate threat from your well-armed neighbors. And they from you.

Lately, the greatest ongoing threat from tyranny, by the numbers, is that visited upon black people by over-armed, trigger-happy, and unindictable police. In what way does your owning guns help, there? Better to disarm the police. But then police have no protection from people (superficially) like you.

Good point. However, if you can see it in all hominids, it's probably legit. ie. strength in numbers + defensible positions vs. predators, preference for sweeping open views vs. predators, etc. Ultimately moving rocks in an agricultural society can begin with the simple requirements to til the fields more efficiently.

In discourse big capital has done well to erase the distinction between personal and private property.

Big capital has been fighting to strengthen private property and eroding personal property.

- ¿Creating a spare part to repair a thing you own?

Those infringe on companies private property so you must have no rights over your personal property.

Does narcissism (in either of the two variants identified) cause conservative group affiliation? If not -- that is, if narcissism is just as likely to present in individuals with liberal/progressive affiliation as in individuals with conservative group affiliation -- then we should observe roughly as many liberal/progressive conspiracy theories as conservative conspiracy theories. So if, for example, academia and the media overwhelmingly attribute conspiracies to those who have conservative group affiliations, it is reasonable to infer that liberal/progressive conspiracy theories are being granted a status of "normal and rational belief system" that more objective and disinterested gatekeepers would not grant.

Ask HN: How much of your code gets thrown away?
Throughout your career have you noticed any patterns in how much of the code you've written gets tossed? I am 2 YOE, so very junior, and I would say that probably 95% of the code I've written ends up getting tossed?

That said, this isn't to say that I write useless code, it's just that very few things I write are used for more than 1-2 months, at which point our team moves onto different things.

Curious if you've noticed less code being thrown away as you grow in your career, and if not, what the pattern has been for you.
I can appreciate your passion but there is a reason even the golf courses' own web sites don't go into this much detail... nobody wants to read 18 novels per golf course. Maybe for Augusta National but not a local muni. Simple reviews -- great idea. Many examples out there like Top100golfcourses.com . But on your site, I can read your descriptions but still don't really get a feel of whether or not you enjoyed the course, were the conditions good, pace, good value, etc.

Go for it as long as you are enjoying it, though.

> There are some toxic fields of research, but I don't think this attitude is particularly common in the academia.

The author was formerly an economics student, where this attitude is quite common. It might have colored his perspective.
Toxic, or rigorous? To my understanding, this kind of questioning is how the search for truth tries to keep itself from veering off into bullshit, and is fundamental to the whole project.

I work in the corporate world where we incubate a great deal of bullshit; projects, careers, and entire teams enjoy wild success on the backs of purported contributions that do not withstand a moment’s scrutiny. It makes a polite and non-confrontational environment, sure, but also comes with its own kinds of psychic injuries.

Ukraine could probably do better destroying fuel trucks than tanks. It is easier and cheaper, and a tank with no fuel becomes war materiel for Ukraine.

Ukraine probably understands this, but shots of tanks blowing up is good for morale.
A Knowledge Graph is the data in the database, not the tech.

You can absolutely implement this in a RDBMS. There are some advantages to a proper graph database though.

But SPARQL is a dead-end - I don't think anyone is really using that in practice outside a dew public demonstration apps. To a large extent this is true of RDF too: triples are useful, RDF gets in the way.

No.
Moreover, their sequence example for the relational database is just plain the wrong way you would go about that.

In the relational example they give[1], that is how you'd capture "have they done X, Y, and Z" whereas the sequence is explicitly capturing the order those things were done in. If you care about that information, you would design your system for this.

The point could have been that this is actually simpler with sequences, not that it's impossible in a relational db. We already have loads of examples of how to capture this data and put it in order. But I suppose a table with a User, Action, and Timestamp column would really invalidate the point the author was trying to make. Then it's just a select and order by to get the order things happened in.

Couldn't you fix that by just clearing the buffer in between the two calls? It won't be measurably slower to do that because the buffer should retain its allocated capacity.
Definitely agree with the article and thoughts. Little things also make the team feel valued and appreciated, quick thanks, short appreciation/feedback, etc. Feels good.

It's interesting having been on the side of being an employee with manager not acknowledging those things overtime it's wearing. But also tough for owner/manager to make sure to keep doing it too. Either way, a good reminder to keep the positivity flowing

Funded startup with short runway left, options?
I need help deciding what direction to take my startup in the current climate. It’s 3 founders (friends from college) with equal equity (1 founder has a full-time job at another startup but takes the same salary and helps out) and a small team of developers. When we founded (5 years ago) we raised $4m and were focused on big data for healthcare. A few years ago we pivoted to a consumer platform. Currently we have a product in closed beta with 500 users. The problem is that the product isn’t finished and users don’t stay on the platform but there some active users share a ton of data with us. We were thinking we could do an IOT play once we get to market but we haven’t gotten around to building those features. Maybe we can become revenue positive just selling user data for research but that isn’t going to happen fast enough to cover our burn and if we cut the burn we can’t finish the product. I’m concerned because the funding market looks brutal and we have less than a year of runway. The founders don’t agree which direction to take the company in (but it’s amicable) and the other two founders are super casual about our situation. What are our options? Is the funding crisis overblown, and maybe we could raise money? Is it possible to be acquired maybe for our team or technology and find a new home? Are we better off shutting down?
