hemmer··on 3D scanning by dipping into a liquid
I wonder how much of a role wetting/capillary effects play in this? The liquid interface will distort as it approaches the object, and will try to meet at a certain contact angle (based on surface tensions etc). Correcting for this might help improve the resolution of the scans?
hemmer··on A Year After ‘Pokémon Go,’ Where Are the Augmented-Reality Hits?
This is speculation, but perhaps there's a game-theory issue here. If IEEE loses money by people pirating (and you can apply the usual counter-arguments about whether the pirateer would have gone on to purchase it anyway) rather than paying then publishing costs increase to cover that loss, and therefore hurting the authors who must cover that increase in future if they want to publish in the journal again.

A better situation is where the preprint or open access version is available.

hemmer··on Giant ‘Arrows’ Seen From Space Point to a Vanished World
Interestingly, these look very similar in design to so-called bacterial ratchets (see Fig 7 of [1]) which allow swimming bacteria to be sorted by size or swimming speed etc. People have even used these ideas to create tiny bacteria-powered motors [2].

hemmer··on O Reader My Reader – Remembering Google Reader
I've tried a variety of RSS readers recently for keeping track of academic publications (arxiv and journal feeds etc). I've settled on inoreader [1] as this: (i) includes a search feature in the free tier, (ii) has keyword highlighting (useful for trawling through long lists of papers), (iii) has a reliable Android app.

hemmer··on Random Walks: the mathematics in 1 dimension
There is some more information and references here: http://mathworld.wolfram.com/PolyasRandomWalkConstants.html
hemmer··on Fourier series
It's interestingly that the Gibbs phenomenon appears visually as a whiplash effect. You can see how it would only get worse as higher order terms are included.
hemmer··on Relaxing with Runcible, the circular 'anti-smartphone'
This reminds me of the aesthetic in Her [1], which was summarised nicely here [2] by the production designer:

  "You could say that Her is, in fact, a counterpoint to that prevailing vision of the future–the anti-Minority Report. Imagining its world wasn’t about heaping new technology on society as we know it today. It was looking at those places where technology could fade into the background, integrate more seamlessly. It was about envisioning a future, perhaps, that looked more like the past. “In a way,” says Barrett, “my job was to undesign the design.”

hemmer··on Number of legal 18x18 Go positions computed. One more to go
I wonder if this sort of thing might be appropriate for grid computing, e.g. BOINC? There are plenty of mathematically minded projects.

hemmer··on FourShadows.js – Time-aware algorithm driven shadows for icons
I pictured looking top-down at the object, for which the shadow seemed quite natural?
hemmer··on Panasonic and Tesla Sign Agreement for the Gigafactory
There was a recent discussion about cylinders on HN which might be of interest: https://news.ycombinator.com/item?id=8097125
hemmer··on Geologic Map of Mars
This is lovely, would probably make a nice print! I'm working my way through Kim Stanley Robinson's Mars trilogy; this makes a great accompaniment.
hemmer··on Ask Stack Overflow for Atom
This might be an interesting idea for a vim plugin too, need to teach myself vim-script first...

hemmer··on Man Walks Nearly 3000 Miles Through China
I too would recommend these types of walk - a couple of other ideas for long trails that I've particularly enjoyed:

- Lykian Way, Turkey (http://www.lycianway.com/)

- Rota Vincentina, Portugal (http://www.rotavicentina.com/)

hemmer··on The Impossible Music of Black MIDI
I would suggest Dan Deacon for someone who writes "unplayable" yet very tuneful pieces: eg.

hemmer··on Juce: An extensive, mature, cross-platform C++ toolkit
I've been using JUCE for a couple of years for VST development. I've found it to be a very well put together library for audio work (diving straight into Steinberg's SDK is pretty daunting for someone new to audio like myself), and a lot just works out of the box.

There is strong leadership from Jules on the direction of the library which is generally a very good thing, though it does mean that sometimes there isn't much room to budge on controversial issues. Font rendering is one aspect that several have battled with for a while, I've struggled to get good crisp smaller fonts without resorting to using freetype. Jules argument seems to be that small fonts shouldn't be used period, therefore the library wont render them well (I think there are technical as well as philosophical reasons for this, particularly on OSX). While I agree they should generally be avoided, there are certain situations where this isn't the case (reproducing an exiting GUI for a client, fitting non-critical text in when screen real estate is at a premium etc).

Overall I would certainly recommend for anyone starting out in audio development, but be prepared to fiddle around with fonts; I'm not so familiar with the non-audio parts of the library.

hemmer··on Gift for a 10 year old
Possibly a raspberry pi (with camera)? A fun project might be to make a bird house webcam or similar.
hemmer··on The Quantum Zeno Effect actually does stop the world
The Ask A Mathematician page linked is quite a bit better.

hemmer··on Music lovers, here is an invite to join our streaming curation platform
Looks interesting, nice to see last.fm support out of the box. Could anyone quickly clarify what the difference between "adding" a song and "liking" it is?

EDIT: if you start playing a new song in a new tab it doesn't stop the old one.

hemmer··on Show HN: Blynde – A new way to listen music on Youtube (user:demo, pwd:123456)
Really only to be able to scrobble the tracks you listen too. For example other music services (Grooveshark / Hypem) let you connect your account and keep track of everything you listen to.
hemmer··on Show HN: Blynde – A new way to listen music on Youtube (user:demo, pwd:123456)
Awesome, very nice interface! One thing I've been looking for for a while is last.fm support (while watching youtube videos). Any chance that could be possible?
hemmer··on Mendeley users revolt against Elsevier takeover
This looks great, however Windows only is a bit of a deal breaker. Definitely going to keep my eye on it though.
hemmer··on Mendeley users revolt against Elsevier takeover
I really like the way Mendeley handles notes, specifically highlighting / annotating PDFs. Do you know of any alternatives that include this? I was planning on writing my own at some point but it might be a bit ambitious.
hemmer··on AudioGL: 3D Modular Software Synthesizer & Sequencer
It does look like a very exciting project but I'm slightly worried that Ableton's legal team will not be too happy with it. There seem to be quite a few visual similarities, I'm assuming this sort of thing would fall under Ableton's intellectual property rather than the devs?
