Re: 3D Printing & Air Quality – A Practical Guide

Johntron — Fri, 08 Jul 2022 17:29:37 -0000

This is a superbly written article for professionals and nerds like me; however, it doesn't really help hobbyists. Dave Frick alludes to a problem for hobbyists: cost. I doubt many hobbyists can justify a $1000 fume extractor and a $250 enclosure on top of the cost of their printer, much less installing vents in their house.

Instead, hobbyists might focus on limiting exposure, lower nozzle temperatures, nozzle size, etc. This means we need to close that huge gap in research between 1 hour and 40 hours, as this is really what hobbyists need to know. I'm looking forward to seeing more research findings in the future

Also, regarding this part:

"[A]s the printing process goes on, VOC emissions generally fall to low levels after around five minutes. [...] VOCs bind readily to particles, which helps drive down VOC levels."

... It's important to realize that if you're using a HEPA filter, those VOC's might not have anything to bind to and remain in the environment.

Thanks again.

Re: HelpDocs - Firmware upgrade and flashing

For the Mk3 on Linux, where do I find the firmware updater? It's not in the linux archive. Do I need to use the Rambo addon for Arduino?

Re: Don't use || to set default values in JavaScript

Splitting hairs here, but Elvis operator is more precise - the operator's semantics are based on false-ness, not null-ness.

I'm not trying to be rude, but you're basically saying don't use a JavaScript idiom.

Re: Analysis of generators and other async patterns in node

Johntron — Fri, 17 Jan 2014 15:05:36 -0000

For me, the lack of stack traces is a real show-stopper. Anyone that's ever *joined* a project rather than *started* one knows how annoying it is to not even be able to use a debugger. I hope we see more of the generator libraries supporting better stack traces like genny.

Re: How Using State Diagrams Can Make You a Better Web Coder

Great article! I'd love to know more about Harel statecharts. These are part of UML now, so it'd be great to know how to draw diagrams for more complex systems.

Open the start menu and search for "cmd". Run this, and it'll give you a terminal. From here, type: python <path to="" json.py="">

Re: Translating my Git workflow with local branches to Mercurial

Johntron — Mon, 14 Oct 2013 12:03:50 -0000

Wow, I love this. I'm still new to mercurial (git veteran), and hadn't thought about doing it this way. I'm curious to see what others think about this approach.

Re: Collective Intelligence, We’re Coming!

Johntron — Mon, 08 Nov 2010 14:11:50 -0000

I think the problem is the difference between reputation and contribution. To many people, reputation is very closely related to popularity, whereas contribution is something completely separate. Simply being able to see how an editor has contributed to a specific topic can be very useful. Also, some kind of executive veto could be useful for people trying to edit topics they were personally a part of (like Jaron).

Why would you become a sloth if you have a cybernetics to improve your metabolism?

What responsibilities? Dying when you're supposed to? Not punching through other people's walls? Not eavesdropping? All valid issues.

Re: Uh oh! We’re all pirates! Who do we steal from now?

Johntron — Mon, 25 Oct 2010 10:43:39 -0000

I don't think it's a chicken and the egg kind of thing. I think the only way we think that is because in the past, people primarily got new music from industry, and not from more artist-centric sources like Pandora, Last.fm, or even Apple's iTunes Music Store. I think as more and more services like this develop, the industry will deteriorate until music rises to the top more organically. We're already seeing this with bands like Arcade Fire.

As far as my argument on free information hindering innovation, I think a good way to ensure and even improve innovation is by giving artists access to tools of distribution.

I'm a software developer and have done some iPhone hacking. Is there anything I can do to help?

The back is attached to the tin casing with double-sided foam tape. This helps isolate the board from the metallic case and keeps things from moving around. Here's an image of a bare PCB: http://mintyamps.com/store/...

I completely agree, especially with your first paragraph. It's important to realize that everyone's different. Judging people is slippery slope, so I personally try to avoid it. Thanks for the comment!

Re: Woices Brings Geo-tagging to Audio

I'm one of the developers for Placethings. We're going to have a feature-rich website (with fullscreen maps) to view and manage content published from the mobile applications. The site will contain pages for every user, a public timeline, and popular/featured content. Users will be able to login (using Twitter, Facebook Connect, or Placethings), manage their content (video, images, audio, and text), add friends, and explore using the website or a mobile app.

We've also got a whole bunch of ideas for more specialized types of content, but we haven't decided on which ones to focus on. Recently we've been tossing around ideas for augmented reality games with our colleagues of the EMAC program at UTD.

We've built the system to be open, so developers will be able to use our API to build their own apps.

Which sidewalks and curbs?

Agreed. How will this money be spent? I can't believe so many people voted for this without knowing what it's for. Does everyone know something I don't?
