xn··on The hero we’ve been waiting for is a map
This is an ad for Esri
xn··on YouTube banned my debunking video but leaves deadly how-to vids online, 34 dead
The questions were meant to be rhetorical questions, but did get plenty of informative answers that using jumper cables with a 12V car battery is unlikely to result in accidental death.

Any article/video that says N number of people died doing X should provide some context about how many people do X, how many people die doing Y, which is similar to X.

xn··on YouTube banned my debunking video but leaves deadly how-to vids online, 34 dead
Is 34, about 6 per year, a lot? How many people do fractal wood burning? How many people are electrocuted using jumper cables on cars each year?
xn··on Faced with scooter seizures, Bird pays property tax bill months late
For those of us not from Texas, this article informs us that Travis County, which covers Austin, charges ~2.5% annual property tax on personal property owned by businesses.

Bird owns personal property (scooters) worth about $6M in Travis County.

xn··on A man who uploaded 2M videos to YouTube [video]
This video could have been a tweet
xn··on Automatic supercuts on the command line with Videogrep
Enjoying the serendipity of finding the right tool at the right time: https://twitter.com/xn/status/1528845032438083584
xn··on My Life as a Mentalist
Apparently he's not the thought sending type of mentalist.
xn··on A Proposal for NFTs with Actual Property Rights
My goal was to encourage those enthusiastic about NFTs to focus some of their energy on solving actual problems.

I certainly didn't evaluate whether the trade-offs between an NFT-based counterfeit-resistant ticketing solution would make it better than a centralized one, but it's at least conceivable that making use of a public-access transaction processing network that also maintains state about current ownership could make the overall costs lower than a solution built upon more traditional payment rails and state-management applications.

xn··on Ask HN: Why is Docusign a $50B company?
I don't know what's legally binding in your jurisdiction, but in the US, scribbling on a PDF will suffice for most purposes. xournal++ is a free tool that will support this.
xn··on Math Problems for children from 5 to 15 (2004) [pdf]
Sunshine Math is a great set of math problems for grades K - 8. I couldn't find a publisher, but PDFs of scanned copies are available online.
xn··on Q – Run SQL Directly on CSV or TSV Files
When working with large csv files, you're better off importing the file into a sqlite database if you want to perform more than one query.

Knowing the import is happening behind the scenes is useful when you hit performance problems with the tool.

xn··on Gromit-MPX Lets You Draw Anywhere on Linux Desktop Screen
Thanks for sharing. Looks like gromit-mpx fixes one of the longstanding bugs in gromit in which new strokes often cause a line across the screen (from the end of the last stroke?).
xn··on Show HN: Grit – a multitree-based personal task manager
If you add confidence interval estimates to each task and a way of inputting the amount of time you can allocate to grit-managed tasks, you could calculate estimated task completion dates: https://www.liquidplanner.com/support/articles/statistically...
xn··on Why can’t you buy a good webcam?
I've been happy with the quality of the Logitech 4K Pro sold by Apple. Works great out of the box with linux.
xn··on Amazon destroys $1.5m of sellers inventory – now homeless
I don't understand why the journalist didn't contact the manufacturers to confirm that the products were authentic.
xn··on Ask HN: STEM toy for a 3 years old?
Our kids liked the Robot Turtles board game. The kids are the programmers, playing cards to give instructions. The parent is the computer, executing the instructions (while making silly sound effects).
xn··on Ask HN: What tools do you use for data munging and merging?
Visidata (http://visidata.org/) is my tool of choice these days.
xn··on Kofola, the Cold War Drink of Czechoslovakia
Kofola also owns Vinea, which is a much better soft drink.
xn··on Ask HN: Developers, how do you estimate projects and write proposals?
If you use a confidence-interval estimates, you can choose how wide to make the confidence interval. I use 80% confidence intervals because that's what supported by the project management tool I use. 10% of the time, the project should take more than the high estimate (and 10%, less than the low estimate).

If you use a 99.9% confidence interval and miss the high estimate, then you're probably over-confident. (And your estimate was probably too wide to be meaningful.)

xn··on Ask HN: Developers, how do you estimate projects and write proposals?
I use ranged estimates with LiquidPlanner. I send a project plan showing the estimates and expected completion date. If the estimates are wide, I explain that I can make them narrower by spending more (billable) time doing research.

Here's an example for a small project with a new potential client I met with for about 20 minutes: https://gist.github.com/bc2f83544b210f81715c4f4175fca985

Estimates are fairly wide because I haven't seen any of their code, just a brief screenshare and a description of the work they would like completed.

xn··on Show HN: Buy Me A Coffee – A free, fast and friendly way to receive donations
In most cases, that charge isn't passed on to the buyer/donor. When it is, it should be made explicit.

Nonprofits sometimes make it an option, e.g. "Add 3% to your donation to help offset credit card processing fees".

xn··on Show HN: Buy Me A Coffee – A free, fast and friendly way to receive donations
Is the donor charged a different amount based on whether they pay through Stripe or Paypal?

If I go to donate $5 at https://www.buymeacoffee.com/xn, it looks like I'll be $5 if I pay through Stripe with a credit card, and $5.45 if I pay using PayPal:

xn··on Show HN: Buy Me A Coffee – A free, fast and friendly way to receive donations
If you want a free, fast, and not so beautiful way to accept a fixed amount with a Stripe account, here's a simple application with a Deploy to Heroku button: https://github.com/cwarden/pay
xn··on Ticketmaster is a horrible company
I bought tickets to the San Diego show on the Vitalogy tour from ETM. They went out of business in 2000: http://articles.latimes.com/2000/jun/20/business/fi-42758
xn··on Opendoor, a startup worth emulating
The Opendoor model doesn't seem much different than how relocation companies work apart from more directly marketing to homeowners rather than corporate HR departments.
xn··on Thank HN: From Google form to $1k in revenue in one month
All new job listing sites should follow the lead of AngelList and StackOverflow, and include a salary field.
xn··on Show HN: Patat – Terminal-based presentations using Pandoc
I like tpp (http://www.ngolde.de/tpp.html). Syntax is easy to learn. It can simulate shell interaction and you can shell out from within the presentation.

And it's been feature complete for a long time. I just tried viewing a short presentation I have at BayLISA nine years ago (https://gist.github.com/cwarden/1349583), and it looks fine.

xn··on Point – rethinking owner-occupied residential real estate
The calculator won't let you enter an Estimated Ending Price lower than the Current Home Price.
xn··on Point – rethinking owner-occupied residential real estate
Sounds like a good way to hedge against declines in your overvalued property without having to move.

"If you don't sell, you can buy back Point’s stake at any time during the term at the then current appraised property value."

xn··on Docker for Mac and Windows Is Now Generally Available and Ready for Production
GA would probably be a more appropriate description.
