I don’t think the previous system was using space heaters though, the PTAC they had before presumably had a heat pump in it if it was generating condensation.

Yeah AVP/passthrough would make you very sick if you tried to wear it in a jet pulling high G maneuvers.

The temperatures we’re talking about (1000C) would be incredibly dangerous in residential applications, plus a small installation would lose too much energy to the environment due to the ratio of surface area to volume. More practical IMO is to use a daily cycle like what Harvest Thermal is doing: store energy in your water heater tank during the daytime and release it at night.

Apparently I’m the only one here who doesn’t know this but: What is RAG?

Also radiosity for offline rendering got largely replaced by sampling based techniques, first things like photon mapping and more recently by path tracing. Sampling approaches are easier to parallelize and generalize better to other types of materials.

FYI this post was actually written by Maya the intern (Matt only writes the weekday posts).

Yeah it’s the trials that are really expensive, not the basic research. The government gets to spread its dollars around to lots of individual researchers but if they were instead using that money to fund phase III trials (1) we’d have a lot a lot less money for basic research (2) we’d fund a lot fewer phase III trials so (3) we’d see much less drug development overall. Also I’d worry about a potential conflict of interest if the same government is conducting and evaluating the results of drug trials.

I guess I would have assumed the opposite? A virus that just jumped from bats to humans is expected to evolve pretty quickly in the binding domain as it “learns” to better target human ACE2. I thought the reason they targeted spike was that it’s on the surface of the virus and so an obvious target for antibodies to attach, whereas if you target some structural proteins deep inside the viral structure you’re taking a risk that the antibodies won’t be able to reach them.

Yeah broadcast TV content has long consisted in large part of reruns, syndication, and older (cheap to license) movies, think of what was showing during non prime time hours when you were growing up. If anything there’s much more new content now thanks to the streaming wars.

You need to clean the filters regularly so they don’t become a fire hazard due to oil buildup; the better ones should have some kind of reminder system and will have filters that are dishwasher safe.

Sometimes there are other regularities in the data that an ML algorithm can exploit; for example, if it can detect feet strike events in the IMU stream, it can compute an estimate of how fast someone is walking that is independent of integrating accelerations.

The oral polio vaccine is a live vaccine and occasionally reverts to an actually infectious strain. This isn’t a major concern in countries where people are widely vaccinated but would be an issue if we considered it eliminated and stopped vaccinating segments of the population. https://en.m.wikipedia.org/wiki/Polio_vaccine

I am not an expert, but there has been a lot of hope recently that because we have much better understanding of protein structure (e.g. https://cen.acs.org/pharmaceuticals/vaccines/tiny-tweak-behi...) and because mRNA allows us to tightly control the genetic sequence, there is hope we could target some part of the virus that _is_ well-conserved across variants. e.g.: https://pharmaceutical-journal.com/article/feature/preventin...

Propublica has been covering this, the FDA has been throwing up barriers to rapid tests while Europe has been embracing them. One of the barriers is that "users are supposed to be able to execute the test without training " which I suspect is what's leading to the inclusion of optical sensors etc. https://www.propublica.org/article/this-scientist-created-a-...

I also feel like the way Tesla drives is really aggressive, I basically can't use is adaptive cruise control in slow/stop-and-go traffic because it ZOOMs right up the the car in front and then slams on the brakes, rather than just going along at a reasonable pace. Similarly, in this scenario with this visibility I might choose not to drive 10mph over the speed limit.

In this formulation I believe the last bit would also be repeated 3 times, and you’d have to read those three bits to detect corruption.

While this is possible, longer credits mean more filmstock to be duplicated and fewer showings per theater screen, so there is an economic incentive to keep them as short as possible. I know when I worked in the VFX industry an artist had to clock a certain number of hours on a given show to be given credit for the work.

Structured light cameras like Project Tango or Occipital's Structure sensor that project a textured pattern would work well here. Stereo algorithms like the one you linked that use the regular phone camera are likely to struggle here, because flat, blank walls are a worst-case scenario for them (yes, they're using the accelerometer to assist, but the reconstruction still needs texture).

Auto-vectorization is impossible for a lot of real-world code because it requires changing how data is laid out in memory. Notice that the AVX version of the raytracer actually involves packing blocks of x components into a single 256-bit-wide variable. Realistically, a compiler is not going to be smart enough to figure that out.

Space carving is a similar idea [Kutulakos and Seitz, 2000]: http://www.cs.toronto.edu/~kyros/pubs/00.ijcv.carve.pdf

Also food price increases look to me like they're basically within historical norms? The posted graph makes it look like there's a big spike because it starts with the 2008-2009 time period when inflation was actually negative. http://research.stlouisfed.org/fred2/graph/?g=hxh

Why assume that anyone who isn't deeply expert in the technical details of a product isn't a full-time employee of the company? Many companies hire sales/marketing people of both genders that may have a relatively superficial understanding of the inner details but are more enthusiastic and outgoing than the engineering staff.

Okay, so these papers are phrased a little confusingly, but what they're really doing is solving a specific but very useful type of linear equation Ax = b where A is a diagonally-dominant matrix (entries on the diagonal are larger than the sum of the off-diagonal entries). It happens that graphs are equivalent to matrices, so it's a neat area that straddles applied math and computer science.

It's a refundable credit, meaning that the government will reimburse the company for VFX work above and beyond its tax liabilities. How is this "tax jurisdictions competing" and not a direct government subsidy? http://www.bcfm.ca/faq/#pstc4
