$BILLIONS

I mentally read this in the same voice I read $VARIABLE with.

FWIW there are dozens of university ranking systems and every university says "look how well we rank in X!". It's been 10 years since I looked, but I think I recall some of them being funded by unis too.

Nonetheless I agree they're doing stupid stuff that's not in the interests of students, staff, the country, humanity and education in general. Alas it takes them many years to feel the bad effects of bad decisions.

Are red & blue lines under the pic are the calibrated references, whilst the car pics are not?

Fwiw the government paper is linked elsewhere in the EFF article,

Woops, sorry missed that. Thankyou :)

A little annoying to track down the sources.

The EFF article links to a Neowin article that then links to a Guardian article which then links to the Gov's proposal paper; but only vaguely mention's Apple's reply submission that you have to find yourself.

Only briefly glanced at Apple's reply (sorry), yeah it's what you'd expect. Take away our power and our business can't protect you from bad people that don't pay us.

and all of the suggested ‘improvements’ to ASIC’s changes are in favour of business owners with no mention of investor protections.

There is also the angle of the everyday consumer. Companies seem to get worse after going public. Encouraging companies to go public could have consequences on consumers (and therefore the economy).

not the reality

Knowing how, when and why something was altered is very important. It tells you a lot about the people involved, their motivations and even their "voice" as you put it.

I asked my grandparents about some B&W photos of their wedding where their faces looked suspiciously smooth compared to the rest of the image. Apparently they were touched up by hand.

(Not saying that's what has happened here, you could be right and it's a modern edit)

pungent oder of RTV gasket maker

Just if you're interested: there are a tonne of different silicone chemistries.

Single part curing (no mixing needed, cure when exposed to air):

  • Acetoxy (emit acetic acid)
  • Alkoxy (emit methanol)
  • Acetone
  • Ketoxime (don't know if this one smells)

Two-part curing (you have to mix the two components, then it starts setting):

  • Condensation cure (tin catalyst) cheaper
  • Addition cure (platinum catalyst) basically better in every way but more expensive

Yes it looks like it's adjusting the port length. (In plain english: some speaker boxes have an intentional hole in them, if you adjust the length of the pathway that sound takes to exit the box through this hole then you adjust how bassy it sounds).

To add a hollow cavity into the plastic part would immensely complicate the design of the moulds (assuming you try and implement the cavity in the same style & orientation of what gluing that bit of wood in achieves). The plastic shells of this speaker look like they've been designed for two-part moulds, which is the cheapest and simplest way of designing a mould. Any internal cavities of the part would require bits of steel mould to be in the cavity during injection, those pieces then have to be removed somehow and that would be a nightmare. Two part moulds can just be clamped & separated over and over again without snagging on anything.

For the walls of a speaker to reflect sound they need to have a density that is very different to the air inside the chamber. As it turns out basically anything fulfills this criteria, even cardboard makes fine speakers (just don't get it wet or poke holes in it). Plastic vs MDF wouldn't matter here acoustically, both are fine.

Bits of particle board can easily be cut and glued by unskilled workers. For business reasons the injection moulding might be getting done at a different place to the final assembly, and the product manager who wants the speakers properly ported might only be in charge of the latter. IDK.

glue applied likely by a machine

I suspect this would be all human assembly. They'll probably have motorised torque-limited screwdrivers and jigs to hold the parts on during assembly, but still human arms doing the work.

In particular: stuffing the white polyester wadding in would be a PITA for an automated assembly machine. Humans are tolerant of variation and bits of wadding blowing away, pre-programmed movement robots are not.

I'm jealous. Walking height ceilings? Arches???

That (chinook-style solution) only works if both rotors are the same size and speed.

Perhaps Sikorsky's tethers to the ground worked around the problem for that photo anyway. Not sure.

 

According to my mum: "if you even miss a single day they throw the entire jury out and have to restart the whole court case again so that the new jurors can hear all the evidence". I feel that would make longer cases exponentially impractical.

I can't find anything about this on the internet, other than for someone asking this question in America.

 

Location: Sydney, Australia. Found it during bushcare.

The brass barb fitting and the powdery filling suggest some sort of kiln burner to me, but the dark green paint on the outside of the tube looks rather ordinary and not like it has been through high temperatures.

The soft, powdery cemetitious filling has a copper-green tint. Only one end has a hole.

If it were not for the brass barb and coppery fill colour I would assume this is just a bit of structural steel from someone's carport (or similar) that has filled with cement and now been cut to pieces for disposal. But a carport with a barb fitting? WTH?

We find all sorts of garbage in this bushland because it's sandwiched in suburbia. Traditionally it was a dumping ground (mattresses, furniture, asbestos, whole cars) and today still people use it illegally as a dump (mainly building materials and soil). Lots of random materials get deposited by or uncovered by stormwater runoff & floods too. There is no limit to the craziness of what you find here.

 

The new theme seems deadset on replacing content with whitespace, driving my father in particular mad (he's having more luck finding Australian news on DW than the ABC right now; and he is sore that he has to hunt for the "Science" news category now in menus).

Not sure how long they'll keep the ?future=x flag available, but for now it gives you about double the number of articles per page.

 

8PM (right now) +/- 10 hours

Better call the tiberium harvester back in.

 

Encountered this fellow during bushcare today. He was sitting right on top of the bridal veil roots we were pulling, looking suspiciously like a rock.

We probably shouldn't have handled him (I hope turtles don't get dizzy from being turned upside down). We put him back down and hid him under some other groundcover as a local Kookaburra was loitering.

 

I could not find any mentions of these problems online. The article itself has no technical detail.

Looking forward to seeing what the actual problems are. It seems this is the first product to market.

Guesses based off the general subject matter:

  • Silica concentrations probably vary depending on the exact position of your head, especially since it's heavy material. If you mount this sensor even a few meters away from a worker then it's readings could possibly become invalid, eg because an angle grinder is firing dust a different direction to the sensor.
  • Silica is a slang term for a very big category of materials. Some might look completely different to others under certain laser observations, leading to some getting missed (bad) and others materials triggering false positives (leading to the sensor's screams being ignored by workers).
  • Self-cleaning routines might be needed to stop it clogging up, otherwise the sensor starts reporting a higher baseline. They could either choose to report this ("pls clean me" light comes on) or ignore it (bury head in sand mode).
  • Alternatively it's performance might actually be fine, but perhaps it's still being spruked inappropriately. Government involvement in funding the project might (?) magnify this problem.

“And then we’re going to add this suspension into some hexane. I mean here I’m just using Shellite because it’s from Bunnings and I dunno who else uses this so I feel like if I stop buying it Bunnings will stop selling it so, it’s like a couple of bucks and it’s like hexanes, it’s so good, Bunnings keep selling this please”

 

I accidentally held down the photoshoot button on my phone and ended up with a sequence of photos of the same scene taken over about 1 second. Interestingly the series of photos contains two very different styles of image:

The first photo looks how I'd expect. Sky is overblown from the clouds and foreground of the forest is dark.

The second photo has somehow magically made the sky darker and the foreground brighter.

At a guess I think a software algorithm is trying to separate the foreground and background, then individual levels adjustments are being applied to each region. Checkout these two close-up crops:

The first photo shows what I'd normally expect from a camera (bright light bleeding into the trunk), the second shows a white halo around the trunk on the sky (probably artificial/software blending from foreground to background). I think I can also see see some evidence of artificial sharpening on the trunk texture; or perhaps the photo was just better in focus (some of the photos were a bit blurrier than others).

I'm using a Pixel 3 with OpenCamera.

Does anybody know what this feature is called and more info about it? I'm particular interested in how binary it is -- it's either activated or not -- some some heuristic must be involved.
