Re:Ask HN: Should I test my garden for lead? on Thursday May 05, 2022 @06:42PM (#31279192)
If your garden is in the front yard of a house located close to a busy street in an old neighborhood, maybe so (not sure of the risk). But in the U.S., cars manufactured after 1975 used unleaded gas, and leaded gas was no longer sold after 1995. So I would think that in any subdivision built after 1975, the risk of lead in the soil caused by car emissions is very low. If any kind of industrial facility was previously on your land, you should test for more than lead.
Re:Ontario's Computer: The Burroughs ICON on Sunday April 03, 2022 @11:16PM (#30903030)
The founder of Trigon was a guy named Don Tapscott. Back then, he had a gift for hyping the "next big thing". I haven't thought or heard anything about him in decades, so it was interesting just now to find that he has a website (dontapscott.com, of course), and that his current passion is Blockchain.
Re:Ontario's Computer: The Burroughs ICON on Sunday April 03, 2022 @10:18PM (#30902754)
I worked briefly for a Toronto company named Trigon that had a government contract in 1984 to produce interconnected office software (word processor, spreadsheet, calendar) for the Icon. The product was called "Emerald". I don't think the Icon hardware existed yet, we developed on Unix. As far as I know, the company went broke before the product was delivered.

I don't understand the point of this article. Why is PostmarketOS singled out over the 20 or so Linux distributions that run on the Pinephone?

In the case of books, I think the battle has already been lost. I doubt that small acts of charity will keep Amazon's competitors viable at this point.
Re:The economics of pumpkin patches on Sunday October 31, 2021 @11:27AM (#29057653)
The chart shows that 25% to 50% are not "capable" of being sold. I think this refers to losses in the field, such as unripe, overripe, insect or animal damage, etc.

However, the article ignores the fact that many of the ones that are capable of being sold are never sold.

Re:The economics of pumpkin patches on Sunday October 31, 2021 @10:37AM (#29057278)
The article's profit calculations assume that every pumpkin grown can be sold. If you take a drive in the countryside today (last day of sale before Hallowe'en), you'll see this is not the case. Huge piles of pumpkins still at the farm stores, and fields full of unharvested pumpkins. I believe the likely explanation for pumpkin patch economics is that pumpkins serve as a loss leader to attract customers to a farm store.
Re:Ivermectin shows that not all science is worth following on Sunday October 24, 2021 @10:03AM (#28977982)
The problem is that Ivermectin is off patent, so no drug company can make any money from it. Since there is no money for expensive research studies or clinical trials, all the research studies that get done will be low budget and subject to being called "lousy science".

How about just properly reporting and studying the actual facts from one of the very large real world trials, like the one in India?

Re:PinePhone Pro Announced on Friday October 15, 2021 @11:46AM (#28879023)
I am a software developer. I would honestly not have the nerve to release a product with software in the state the Pinephone is in today. But of course, pine64.org takes no responsibility for the software on their phone, it's a "community project".

Until there's somebody who is willing to be embarrassed by the state of this software, and able to do something about it, there is no hope here. It does not get better.

Re:PinePhone Pro Announced on Friday October 15, 2021 @11:05AM (#28878475)
I received a Pinephone in the latest shipment, about three weeks ago. I also got the convergence dock to be able to attach a monitor, keyboard and mouse. I am extremely motivated to get off Android on my phone, and yet my Pinephone has already been discarded (and I never even put a SIM card in it).

There are far too many out-of-the-box bugs and glitches to consider this a usable product. For example, the convergence dock will not display on a monitor. Firefox browser displays too wide for the phone screen, so unusable. A dozen other issues on first day.

Even a development board should work better than this, have documentation of the known problems, and have some support mechanism that works.

I don't think better/more expensive hardware is the problem. It's software, caused by lack of users, lack of investment, and too many "competing" distributions of Linux.

Re:Open Source Tractor on Monday October 11, 2021 @02:38PM (#28831433)
Yes it is. Even if it had a PTO, this vehicle won't do much agricultural field work, it will bog down. Tractors typically have much larger back wheels, usually weighted, and a larger engine.
You have to laugh at the obligatory time-to-market estimates in these lab-grown food articles: "I estimate we are only four years away from ramping up production and having regulatory approval in place."

It would be interesting to see what estimate was provided in the 1974 article referenced in the piece.

Re:Simple Math to Set Up a Sales Team on Tuesday December 01, 2020 @07:00AM (#25264445)
It’s not 10% of revenue, it's 10% of the first year of ARR. So if the company is doubling revenue every year, it is 5% of revenue. Any slower growth, it's a lower percentage.
Re:Ask HN: What are the biggest obstacles to vertical farms? on Tuesday August 27, 2019 @05:47AM (#20807806)
In addition to cost of lighting, I've found that the cost of hydroponic fertilizer is also too high, at least for small growers buying it premixed. I've successfully grown hydroponic tomatoes following standard guidelines, and found that the cost of the fertilizer is roughly equal to the value of the tomatoes harvested.
