bpowah··on Bump Mesh: A vibe-coded, open-source tool for texturing 3D prints
Very nice. I was looking for something like this a few months ago to stiffen some vase-mode prints and quickly found it wasn't worth my time messing around with UV maps in Blender or adding corrugations in CAD. Now I can reboot my storage bin project. Big fan of your YouTube channel as well.
bpowah··on Ask HN: Website with 6^16 subpages and 80k+ daily bots
I think I would use it to design a bot attractant. Create some links with random text use a genetic algorithm to refine those words based on how many bots click on them. It might be interesting to see what they fixate on.
bpowah··on Rigs of Rods: free and open source vehicle simulator that uses soft-body physics
I can't speak for Wine, but my son uses it on Proton regularly and except for a few brief glitches after updates and the inability to use the steering wheel controller, it's worked very well. https://www.protondb.com/app/284160
bpowah··on Apple sets up iPhones to relay location for 911 calls
Undoubtedly desperately needed tech, but I don't understand why the geolocation couldn't be embedded in the voice call itself (14.4k modem style). It's such a tiny amount of data, it wouldn't need to interfere with the call at all, or necessarily even be audible. Why the need for a "clearinghouse" and a third-party private company service lock-in by already stretched emergency services?
bpowah··on 3-D printed plastic objects that can communicate with WiFi devices
So my WiFi should easily be able to detect if my (all metal) garage door is open or closed? I would like this. I run dd-wrt. Is there an all-software solution to this? Or does this research rely on fairly specialized hardware? (sorry, didn't have time to read the whole article)
bpowah··on Ask HN: How would you improve Stack Overflow?
The reputation system should be overhauled. A user-based PageRank-style system would highlight the quality of work over quantity and a high rank would give a user voting power that would take some burden off of moderation.

A monetary voluntary "tip" system (or cash "bounty" system) would be nice too. Talented people would be more willing to contribute if it supplemented their income. Wrought with unforeseen consequences I'm sure...

bpowah··on Show HN: Mailform – Print and Mail in bulk from your browser
We are required to notify (by mail) residents within a specified distance of a map feature. directmail.com uses a geoselection tool that, while suffering from last year's UI, is fairly full-featured:

Can you poly-select on a map to get addresses? Or do I need my own pre-compiled list?
bpowah··on World-record electric motor for aircraft
The original article mentions hybrid but does not say the motors are exclusive to hybrid drives, merely that the motor will be flight tested in a series-hybrid DA36. Besides, the MIT article I linked enumerates the benefits of the hybrid drive. The word 'hybrid' is in the subtitle. I suspect Siemens is focusing on hybrid tech at the moment because battery tech is such a moving target and they want to use an existing airframe. Ultimately, I think all-electric aircraft will find their market in short-flight urban transport applications where noise, pollution, and reliability are huge factors.
bpowah··on World-record electric motor for aircraft
this article does a fair amount of discussion on advantages. Basically it is quiet, has no on-site emissions, and is theoretically more efficient. They also go on to mention that it loosens some design constraints. http://www.technologyreview.com/news/516576/once-a-joke-batt...
bpowah··on Map: The Most Common Job in Every State
Right? Me too. Then it dawned on me: "Software Developer" is just the new "Secretary". Instead of guarding filing cabinets, you are managing a db. Instead of manning the front desk, you maintain the website.
bpowah··on MIT students build a roller coaster in one week
Yield strength for steel is about 5x that of wood's UTS, and the cross-section of a 2x4 is about 5x that of a 1-in bolt, so yeah wood is 'that' strong. Screws are typically used in a way that they are not carrying a static load -- basically just holding the structural wood in place. The static load in a structure is usually transferred wood-to-wood. When you do see steel carrying a load in a wooden building, it is generally surprisingly beefy-looking.
bpowah··on Interact.js – drag and drop, resizing and multi-touch gestures
Great stuff. Works great on a desktop except for the two-finger gestures. I'd love to see a zoom and rotate binding to the mouse scroll-wheel.
bpowah··on The Space Shuttle’s Controversial Launch Abort Plan
In the same vein, there was the proposed MOOSE reentry system: http://en.wikipedia.org/wiki/MOOSE
bpowah··on Show HN: I'm renting a truck to make buying and selling furniture easier
A number of random thoughts come to mind. Apologies if this comes across as negative. I like the idea because it makes selling a hassle-free experience, but the way I am imagining it feels inefficient to me. "Free delivery" == $150 for a $300 couch? Or am I missing something? Does your truck sit for 90 mins during the auction? or are you making more pickups? If multitasking, isn't a truck a FILO storage for a FIFO process? Couldn't I sell on CL, get a bigger audience and hire a delivery/mover service if the buyer doesn't have a friend with a pickup truck? If a mover service is more expensive than you, then why? A quick search looks like I can hire a two man moving crew for $75 an hour.
bpowah··on LAPD adds drones to arsenal, says they'll be used sparingly
Many jurisdictions tried to introduce speed trap cameras decades ago. But they failed to gain wide acceptance mainly due to public outrage. Hopefully, the LAPD will seek a compromise between utility and public image.
bpowah··on Question quality is dropping on Stack Overflow
It's really just a geometric growth problem. I've been a member for 5 years and I feel like it hit it's "Eternal September" a couple years ago. And I'm sure the people who have been a member since the beginning feel like it went to hell around about the time I joined! I've often wished they had an option to filter questions by asker's rep score.
bpowah··on Up and Down the Python Data and Web Visualization Stack
For more involved explorations, I use the editor of my choice and import/reload the script as a module in the notebook.
bpowah··on Tesla Model S – Cost of Ownership vs. Honda Odyssey
I don't understand how the '14 model S is "AWD equivalent".
bpowah··on Show HN: Free, open-source site for finding beautiful hikes
I'm excited to see where this goes. You are right about the competition. There is tons of information out there, but not many are wiki and none have the responsiveness or a clean modern design yours does.

Kudos on the "free and open" promise! I hate logins.

Critique: - I second the suggestion to encourage contributing to OSM. Most popular hikes will be in OSM already and adding them to hike.io could be as easy as selecting the route on the OSM layer. - can you use a USGS layer for US locations? see mapper.acme.com - Adding an entry should be easier. I selected the coords, but was still required to enter the state, country. I would like to simply add a few points on a map and have the elevation/gain calculated for me - driving directions? why a block of text? why not a link to google driving directions?

bpowah··on Shaft passer
It's certainly possible to build. It's a joke because it should never need to be built. There are so many simpler ways to route power around the wheel rather than through it. If it ever became apparent that you needed such a device, it would indicate some seriously poor choices early in the design process. The joke revolves around the wheel/shaft problem, not the cable/cable problem.
bpowah··on Why three prongs?
or have some capacitance of their own.
bpowah··on Why three prongs?
Now would somebody please tell me what the little holes are for in the end of the plug prongs!? http://www.worldofstock.com/slides/BEN2097.jpg
bpowah··on Why three prongs?
Wonderfully entertaining to read. I was once told by a certified electrician (and physicist) that you don't even need a neutral wire and many rural services only have one "hot wire" and use the earth as the neutral "return" circuit (which really just need to have capacitance. I think the author could have started with a "one slot" age. More info: http://en.wikipedia.org/wiki/Single-wire_earth_return
bpowah··on Getty's New Watermark
Yes, they clearly thought thru the white-image issue: http://www.gettyimages.com/detail/photo/ice-extreme-close-up... The box is just a low-contrast region (not adaptive). But I still think there will be lots of conditions where it will be tough to read. http://www.gettyimages.com/detail/photo/chess-board-royalty-...
bpowah··on Getty's New Watermark
What do they do for almost-white images? Hopefully at some threshold they switch to black test. Even at that, a black/white tiled checkerboard image would leave the url illegible. They should have outlined the white text in black.

Also, it looks fairly easy for an "unfair use"-er to "heal" the watermark away. They should consider a watermark with higher entropy. (like a stipple-shaded box or one with subtle random variation in shade around the box edge.)

bpowah··on Who here believes the universe is a computer simulation?
It is a moot question. A simulation is just a name of a thing that is a part of the universe. The current definition covers simple things like thoughts or sentences and some simulations (ex: the Bay Model) are not really distinguishable from the real world. The term simulation may be used to help us think differently about hard-to-get information or help conceptualize some impedance to information but the definition of the term would have to be generalized greatly to apply. In other words, any "discovered" universe-as-simulation (or more more to the point the discovery of the simulation's "operator") would look very unlike any conventional definition of the term "simulation" and would probably just look like "more universe".
bpowah··on Tell congress to stop SOPA with a physical letter
I absolutely love the idea. I cant remember where I read it or heard it, but physical letters do get much more attention. Nothing against SendWrite, but I think even more attention can be gained via distinctive-looking enveloped letters that need to be cut open and unfolded. A stack of similar-looking postcards will have an impact in terms of volume, but will likely be sorted into a bin and never read. If you have the time and have extra company logo-ed envelopes, please consider sending one by hand as well.
