Hi Tom,

Funnily enough, I also started my site, https://carlhu.com, in the late 1990's to post my piano recordings and chamber music, photographs, and writing; and also left it dormant for a decade :-).


Nice! Thanks for sharing it.


The kit looks very interesting. Unfortunately, it appears to me that the Pinnacle kit is not yet approved under the emergency fda authorization, yes? I'm using this web page for reference: https://www.fda.gov/medical-devices/emergency-situations-med....


The in-vitro EUA list on the FDA page only seems to cover PCR tests and not ELISA immunoassays (yet).

Pinnacle's webpage earlier this week said they were shipping to the EU but waiting on the FDA EUA for shipments to the US. The tracking on my order was marked as held up at the factory.

The EUA notice disappeared from their website on Wednesday, it shipped yesterday, and I got it this morning.

It's reasonable to believe Pinnacle obeyed the rules and waited. My plans weren't to use the kit unless absolutely necessary, so I can wait for the documentation to update.


Does this racket-based transpiler provide a REPL?


I was wondering something similar, can I just use Dr Racket for this? :)


I would say yes since Racket is a Programming Language for making Programming Languages :)


I know this is a downer, but given that the article states that 18% of the population are "elite" after 10 generations, and there are 2000 elite foxes now, doesn't "strong selection pressure" imply there were around 10K-30K individuals culled in this project for not belonging to "elite"? Is this normal breeding practice? Speaking as a somewhat guilty owner of a beloved papillon-breed dog.


I think your probably right. But then, 3.8 million animals were killed in Australia in September alone for human consumption.[1]

Although I do feel a bit moralistic about dog breeds that have been selected for specific physical appearance characteristics without much apparent attention given to the animals health. Pugs are a good (bad) example, the RSPCA takes a pretty dim view.[2]

Papillons have only minor health concerns although patellar luxation, seizures, and dental problems can be issues. Additionally they can be at risk for PRA, intervertebral disk disease, and allergies. [3]

It amazes me a bit that "dogs" are all the one species, Canis familiaris (which translates from Latin to 'family dog', cute). I wonder what we could do with humans if we selectively bread them for hundreds of generations.

I wonder what humans could do with "us" (you? them?) if "we" selectively bread them for hundreds of generations!


They were kept for fur so culling would have been the normal outcome. In regards culling for breeding purposes you don't have to physical kill the unwanted individual, you just don't let them breed.


The modern population reproduces elite at a higher rate, 70 to 80%, and was grown from the ~100 foxes that the breeders were able to keep in 1998.

So the 2,000 that they have today doesn't say much about how many foxes they were breeding in the earlier generations (but over 50 generations the numbers culled probably do get into the thousands).


The video ends with a brief second where the cyclist explains what prevented even higher speed. I make out: "too much vibration...", "knees rubbing...", "unable to continue increasing power output". Would love to hear more about this.


Note the video was from last year when they failed to set the record. This year they've done it. They probably will release a video of this year's efforts eventually.


I believe it is because the vehicle is very aerodynamically unstable. When you ride a normal upright bike, it will fall over unless you actively spend a little effort balancing it. Here is a video of a crash: https://www.youtube.com/watch?v=i5Dapy1xUq0 Note how it wobbles to the right when he pushes the right pedal, then to the left when the left pedal is pushed.


Here's the current video of them actually beating the record: https://www.youtube.com/watch?v=33clAZoaLWs


I have the Odroid XU3 (which I think runs the same version of their Ubuntu). XBMC/Kodi runs on it, but I get a crash intermittently when fast forwarding a movie. VLC works perfectly. Chromium and Firefox runs superbly. I was unable to get Flash working so Amazon Instant Video and HBOGo don't work. Wireless with the $8 usb dongle they sell works perfectly.


Have you tried the pepper flash player?

You should check the ODROID forum for newer graphics drivers. The bleeding edge versions are released every now and then as separate binaries/images.


Minus is hiring! We are creating new ways to bring people closer together, to subtract the distance. We are seeking curious, inventive, and self-driven individuals in our New York City midtown office. All full-time positions include competitive compensation, stock options, and benefits.

We are interested in Android, iOS, and backend engineers (we love Python and Clojure). Check out http://minus.com/pages/careers for details.

Insufficient sustainable power output.


I was at Microsoft Research and on the SQL Server Transaction Engine Team when he was there. He was a generous and inspiring leader and teacher. RIP.


Note: We got resumeable uploads working for Chrome and Firefox only. Internet Explorer and Safari still fall back to flash and non-resumeable uploads (respectively).

If you use Chrome or Firefox, you can now drop a file onto a page on minus.com, unplug your network, reconnect, and your file resumes uploading where you left off.

I love the web and am excited to see the range of possibilities for pure-browser features expand.


Can you provide a little more detail on how it's implemented?

Are you using resumable.js[1] or is it a custom implementation?

[1] https://github.com/23/resumable.js


Sure, let me give some further implementation detail.

We were inspired by https://github.com/dmitry-dedukhin/lightweight-uploader, particularly the js implementation from Dmitry.

It turned out, however, that the simple flow control he implemented was not adaptive enough to simultaneously accommodate both low-latency/low bandwidth and high-latency/high-bandwidth connection.

For resumeable uploads to work efficiently for both cases, we implemented TCP/IP-style congestion control (e.g. slow start window size scaling and exponential back-off retry timeout), but over http POST requests instead of UDP packet sends.


Amazing! I thought it's a desktop tool only feature. Really nice to see this feature finally available on web. I'm wondering why it's available on Chrome and FireFox only. How about IE9?


Are you using HTML5 File API with JavaScript? Great to see an image hosting site continue to innovate!


We are, indeed, using only the HTML5 File API and javascript for this feature.
