PSA to folks who answered this: if you have a profitable side project, double down and try making it into something more than a side-project.

If you've built something that is actually collecting revenue, you're already ahead of a huge number of folks out there, and you can likely build it into something that can at the very least make you live comfortably, if not much more.

It excludes recipients in programs that cover well over a quarter of the state’s population, so, no, not “nearly every Californian”.
This question's underlying motivation is disgusting; you should be ashamed of posting such a dog-whistle. Anyway, just tie it to tax-return information, as California is doing; if one doesn't pay taxes, then one can't claim the benefit. Nobody cares about "illegal" status, just about whether folks are working and paying taxes.

Yeah. Looking through the list at least half have SaaS solutions you can purchase off the shelf. The rest you can mostly cobble something together or they just aren't practical.

The Mom Test has a great rule of thumb when doing customer development and that's to ask "last time you needed to do X, what did you do?"

For the inventory management stuff the answer would probably be "I checked my usual spreadsheet and made the orders".

And thats likely what the person will continue to do forever. If they wanted to solve the problem they would have found the software by now most likely.
Not sure about ES, but Solr removed it's max field limit in release 4.0. Text documents tend to be a lot smaller than people expect, both in terms of word count and file size. I think you will be fine with 50 mb if you are using ES.
This is amazing! One thing that allows me to do, which I wasn't before, is to do a search for the repos that use some of my open source.

While there were some tools for this, they fail sort for older projects where using a library meant copy/paste it into your project, which is not reported in the CDN stats, npm installs or github "uses".

Now I can run a search with a bit of code that is only present in my library and find reliably those who copy/pasted it. While I publish my code under the MIT, this would also be very useful for those publishing under the GPL to detect bad actors.
I think most Python, JS, Java etc libraries are "dead" in this sense that you lament about Clojure. The exceptions are the very recent languages. It's natural, most libs don't become popular and flourishing open source projects.

It seems to me Clojure ecosystem is in good shape, a lot of new libs keep coming out and there's a healthy & growing actively maintained set of libs. The Clojure way of data-centric APIs also means that stable libs don't need to be tweaked often to keep them working while the surrounding world changes. In the early days there were more hobby projects published and less serious use, currently the user base is more tilted towards inhouse business software. I grant that it would be cool if there were more stuff like Overtone or Quil from the early days happening now..
I think the idea others are getting at is using docker as a means of setting up a testing environment in your dev env, not using it as a dev env. I tend to do this (though the way you describe would be great too!). I develop locally with intellij but run my integration tests in a docker container (or a few) by packaging up my app in a container. I just make that container look like whats running in prod. Thats the magic. dev looks like prod.
Pascal was actually standardized both as ISO 7185 a few years before C and the same year as C as ISO 10206 (see [0]), however both (especially the second) saw very little interest and any further standardization efforts stopped soon later. Even from its inception (like all of Wirth's languages) it was meant to be extended - even the standard itself mentions that any deviation from it is accepted as long as it is documented. Dialects are much more common in Pascal, pretty much like BASIC (and other languages - standardization to the level of C and C++ isn't really that common).

In practice every implementation was copying features from the most popular of its time - UCSD Pascal in the earlier days, Borland Pascal in later days (and Borland Pascal actually copied a bunch of features from UCSD Pascal). Implementations were running on systems that had enough differences as to not be worth the portability anyway.

Nowadays pretty much all Pascal compilers are either pure procedural Pascal compilers loosely based on the first standard (i do not think the extended one was implemented much) or the object oriented variant introduced in Delphi. AFAIK pretty much all of the latter support the Delphi 7 dialect, so that acts as a sort of de-facto standard.

The UNIX influence was a much much bigger reason that C got so widespread and C++ simply piggybacked on that.

Ask HN: Is it normal to feel overwhelmed when doing competitor research?
I am currently in the process of building a startup. I really believe in this idea, and it's something that I'm really excited and passionate about.

When I first came across this idea, I started thinking about the vision and talking about it with some hopeful customers from the market. After this, I formed a roadmap of what my product might look like in 6-12 months, and this got me even more excited.

However, I recently came across a well-established competitor who has been building a very similar product for the past 2.5 years, and what they have now is really close to my 6-month vision.

This left me very overwhelmed and upset for a few reasons:
1.) I felt really behind; in the sense that the competitor already has out in the market what I'm hoping to build in 6 months.
2.) Why would the potential customers I was speaking with use my product when they can just use my competitor's since it's already established?
3.) Am I just a copycat? This one upsets me the most because this idea is something I'm really excited about and I don't want to give it up.

Is it normal to feel like this? If so, what is the best course of action going forward?
That trick doesn't work when you're talking about infectious diseases. You need to isolate your patients from each other to avoid re-infection and you need to stop rotating your ICU personnel between units or they themselves will become vectors for infection to people who would otherwise recover or may be mis-diagnosed.
A nice book, clearly written with code available using literate coding techniques. Fairly easy to port to a new machine. Were I teaching compiler techniques, it would be on my short list for a textbook.

It's not just salt though. In some countries, the tap water isn't safe to drink, so it's probably not safe to breathe.

Also, as another poster pointed out, humidifying a large room in winter requires several liters of water per day. The cost of distilled water would quickly dwarf the cost of the humidifier itself, so other types of humidifiers besides ultrasonic (namely evaporative ones, where the main danger is mold, which distilled water doesn't help you with) are more economical.
No need to talk about Ada in the past, it is alive and doing well, with more deployments into production that Rust currently has.

Yes the open source around Ada is not that big, not all programming languages need to embrace free beer to stay relevant, if they have something worth paying for.

Right now, they have the certified compilers, ISO standards (open source consensus-by-merit does not do high integrity computing), IDEs, debuggers, and 40 years of experience deploying code into production.

What irks me about Rust is statements like "Now it may be that there emerges another alternative but at present Rust has blazed a memory safety trail that I don't see anyone in a position to challenge", which resemble the meme that "Rust Evangelism Strike Force" has become.

The only thing that this does is turn off the attention from anyone in the known about what Rust might bring into the table.

Finally, Rust's borrow checker also gets bad press, because it still considers invalid code that for a human is perfectly clear that it should compile, hence the Polonius ongoing effort. It also makes it quite hard to do any kind of GUIs without spreading Rc<RefCell<>> everywhere, hence Raph Levien efforts how to improve writing GUIs, and the regular GNOME/Rust meetings.

C++ has not borrowed epochs from Rust, some people were supporting a proposal, which was discussed at Prague meeting and deemed impossible to have such feature without spreading ABI breaks across TU or module interfaces.

This is the real fear that progressives have about UBI... that it's a replacement for government services. Converting government healthcare into an equivalent check will effectively take away healthcare from millions of people.
The absolute simplest semantic I can come up with here (too simple?) would be for a struct containing a non-null owner-pointer to be bound by its owner’s ownership/lifetime-scope.

For most commonly used graph-types this should lead to pretty simple one-directional ownership chains which should be doable (although probably not trivial) for a compiler to enforce.
Thanks for pointing it out, that library looks quite interesting. A question: it mentions it "Supports tensors of up to 6 dimensions.". Sadly some of us have to deal with tensors of even more dimensions sometimes. Does Nim support some kind of equivalent to C++'s variadic templates that would allow creating tensors with an arbitrary number of dimensions?
How would you even begin to imagine a free market around this? To get even the slightest approximation you’d first need to abolish copyright and patents and any other distortions enabling hoarding of imaginary capital, probably need to take a stab at the very definition of a corporation even.

Whatever market there is to speak of currently has very little resemblance to a free market in any case.

Why do you think that people who are not citizens of their resident state are automatically "illegal"? The European Union has made great strides with their experiments in allowing laborers to freely flow across borders, and we now know that it is a boon to economies when labor is allowed to migrate freely.

I mean, guessing that you're living in the USA, you right now are benefiting massively from a system of migrant labor [0] involving the flow of people across the USA-Mexico borders. (And also the USA-Canada border, although somehow I imagine that that bothers you less.)

It seems short-sighted to consider laborers as unfit for the job market just because they have a different country of origin, and it is almost common sense that one should pay taxes where one makes their income and pays their rent and groceries; it is at least economic sense and part of how most countries design their tax systems.

If tax cuts and low interest rates led to more real investment and value creation, you would be right. Unfortunately, they are primarily going into real estate and the stock market ATM either directly or indirectly via speculative investments. There isn’t much real growth out there, and everyone is waiting for the inevitable downturn in the cycle anyways so they are playing to safe.

From what I recall, the creators were not devoid of programming experience. Rand Miller had some experience writing software for banks, and first game required quite a bit of programming. I would suspect Unity is pretty similar in terms of complexity but perhaps not in terms of simplicity of interface.
This reminds me of a good example from work: the emergency stop button on an industrial robot. By definition, the customer should not be pushing it. Pushing it means something has gone terribly wrong. But when they push it, they expect certain things to happen and they are unhappy when they don't.

(Your typically industrial robot does not rely on software for safety. However software can make the robot respond more gracefully.)

How about an alternative idea.

The cost of housing is insane. Prop 13 protects those that were able to buy a home when prices were cheaper, but it screws over the future generations.

Is this fair?

How about the state pays the remainder of housing costs, after a basic commitment amount is met?

Say, a person buys a house. He should be responsible for the first 20 years of payments, which is based on a percentage of his net earnings, like 35% to 40%.

If he stays there for 20 years, and completes the mortgage program, then the house is his. The government will pay the difference, and close out the loan. He will need to continue to pay the property tax to live there, but that’s now like a cheap rent.

The unit must be his primary residence. He cannot rent it out for 20 years. He can transfer it to an immediate offspring or spouse, like a child or wife, upon his death.

I chose 20 years, because this is a long enough time to make a commitment to a location, without being forced to work for 30 years to pay off the loan. And a 35-40% of net, so that he isn’t house poor.

So he can start the program when he is 25 years old, and by the time he is 45 years old, then the house/apartment/condo is his.

This now would tie the price of housing to the price of median pay, instead of some arbitrary market rate.

The short sighted thing that politicians fail to see with the housing crisis, is that it destroys the future fabric of American society. People get priced out of housing markets, and cannot raise a family, because everything is just too expensive.

We need a different way to look at things. The current method is flawed, and has outlived its usefulness.
There are a lot of charlatans in the Data Science space who lack the necessary mathematical background for their roles. For me it was necessary to get a rigorous understanding of probability theory, and applied probability theory is basically what mathematical statistics is about. My background was CS and software so R, Python, data visualisation and ML operationalization is by and large the easy part of Data Science to me. If you pick up any book like Bishop's or ESL you will be extremely frustrated if your mathematical background is not there. I didn't feel comfortable creating predictive models for production use that I didn't completely understand what was going on "under the hood", the assumptions being made and how they could fail. It's the only ethical thing for any engineer to do.

Amazon is a total landfill these days. As much as I hate to admit it as such, my wife does reviews for 'free' products, often paying in addition. I could write a novel on how this system works, but in short I'll say, reviews are completely useless.
I think even a lay person would be able to make some good observations about any product. Then across hundreds of employees you could start to build specialized teams.

But also, you don't want people to be too close to a range of products so they can be somewhat objective. For example is swimming shampoo a real thing? or is it just normal shampoo that costs more?

Here is Australia there is a range of over the counter pain killers, all the same brand, all with the same active ingredients, but marketed at different kinds of pain, and at different price points.

> It’s like nobody understands supply and demand

Folks that use supply and demand principles to argue against UBI don't seem to understand themselves.

If everyone is given $1,000/mo, it does not necessarily follow that living costs will also increase by $1000/mo. For that to happen, the additional $1000/mo would need to actually increase everyone's demand for services, which is generally not the case. Having more money generally does not make you want something more, it just makes it easier to afford it. If more people can afford something and start purchasing it in greater numbers, then yes, the price will increase, but they are also getting something the thing of value in return.

Put another way, giving everyone $1000 will likely increase prices, but the increased prices will be less than $1000.

Looking forward to the collection of modules. Right now I'd say it's a bit too linux centric. Especially when it comes to bringing cypersecurity concepts to new people I think it's usually better to start with basic stuff like SQL injection ('bobby tables') or ARP spoofing. They even state it's aimed at white belts, yet have slides about the different rings in a linux kernel. But maybe that's just my perception. Great anyway!
Cool. Keep up :) definitely gonna share with my co-workers.

You don't need to work on hard problems but in general, solving hard problems is usually more important than creating another TODO app or a bingo card website. The latter is more likely to make you rich (for certain definitions of "rich"), and yet the former could, if successful, be fundamental for the progress of humanity; but, you know, it's hard.

> Everyday people honestly don't understand why prices are what they are. I've had a number of conversations with people and they truly believe that prices are arbitrarily set based on how much owners want to screw customers over.

Generally, a company will charge the highest price they can get away with, irrespective of the cost it took to produce the good or service.

Prices only approach the cost of production when there is strong competition among industry players. Basic tactics like branding, consolidation, and lack of transparency in an industry help subvert competition.

I'm not really advocating one way or the other, just pointing out that property taxes are usually constructed such that the owner pays a flat rate based on an assessed value. There is no tiered increases in rates as the value goes up, so it's pretty much a classic example of a regressive tax.
