Most of the stuff you'll find on the web is pretty old. In most industries it's not really a big issue-- waste management and industrial pump manufacturers don't change that quickly. But obviously in semis it matters more.
If you know anyone who works at a hedge fund or investment bank, you can ask them to grab some primers for you. All the big banks produce them for the major industries they cover. But they usually watermark every page of the report with the name of the client to discourage people from sharing more widely.
https://i.redd.it/ooln252yxjna1.png - Here's a visualization of the size of the banks which collapsed. It does not include FRB which was comparable to SVB at about ~200B AUM.
As you can see, we're nowhere near the number of banks that could collapse, but, with the collapse of FRB, we've passed the total AUM of banks which collapsed during the height of the '08 GFC. So, that's a little staggering...
Personally, I'm not expecting any others to collapse, but I also wouldn't be surprised to see up to five more. Moody's downgraded six banks when SVB collapsed - one was FRB. All of the others seem to be doing okay for now, but only one (Western Alliance) is trading higher than its price at time of downgrade.
Most toasters suck. I have to buy a new one every other year or so, for some stupid electrical or mechanical reason. Right now, for instance, the latch on our current toaster -- the one that latches on to the handle you press down to lower the bread and close the circuit to start the heating elements -- isn't latching any more. Fucking low-grade crap! I mean, I'm not asking for a self-lowering magically-correct-degree-of-toasting toaster like in the old TC video -- I just want a stupid mechanical latch in a product I bought a couple of years ago to keep stupidly mechanically latching for six or ten more years. That is not too much to ask.
So, stick to your complex medical instruments. Or, if you switch to toasters, please don't build the same shitty crap as everyone else.
Here’s an old school high level overview of pupil tracking methods[0]. The focus recently has been moving these older computer vision methodologies to ML without introducing too many errors.
Disclaimer, I am the primary engineer of a commercial eye tracking system.
Tools like these popup every now and then are a nice tool for rough estimation of gaze. Fixation tracking is a large complicated issue that usually requires some sort of calibration to get more precise results. By sidestepping the calibration problem, much higher subject compliance can be achieved since you don't have a grad student barking confusing order at you. The downside to this is the noise you see in the tracking results. For those interested a product that produces similar results is
pupil labs ambient gaze tracking "Core" research headset[0].

Author here (I didn't use Show HN because it's a larger collaborative project). Yes this is basically a tradeoff between accuracy and flexibility+accessibility.
For usability testing, physical eye trackers have to be used one person at a time (no simultaneous use), use an experimenter's time to schedule and administer, can only be used for a short period, and only work with local participants. But yes they will probably always have better accuracy, and detect saccades/fixations better which are also great for psychology studies.
The other thing is if you want to make a consumer application (like browser game, or accessibility mode), then it's more practical to have people just consent to having their webcam turned on, than to go out and buy an eye tracker.
In your estimation, how far away are we from eye-tracking software being able to detect the start of a microsaccade, estimate where the gaze is moving toward, and draw new contents on the screen there before the gaze even reaches that point? I would think that by "hacking" into human brain "vulnerabilities" like saccadic masking and chronostasis, such software could potentially yield seriously trippy and mind-altering results!
There’s two parts to that implementation of such a system, and they’re both interesting! The first part is detection of a micro saccade which is already available in research systems I have personally worked on. You can basically crank up the camera frame rate until you’re around the micro saccade range and do some clustering analysis on the positional data to decouple the hardware moving vs the face. The second part is having a fast enough reliable commercial grade displa system to present stimulus on. Displays are very fickle in practice and getting your hands on one that can run with adequate color, contrast, and brightness at speed is currently very difficult. One angle under research currently is the perception of stimulus during saccades and micro saccades. There’s quite a bit of time and effort in the industry going into neurological assessments through saccades, the tools coming out of this are really starting to come down in price. This opens the door for a bunch of lower priced research options, such as the parent article, to enable a much more rapid pace of understanding.
For the duration of the microsaccade, you're blind. So if something changes onscreen it's much harder to see.
IIRC people have used small orientation changes during microsaccades for redirected walking in VR. You feel like you're walking straight but you're actually curving back on yourself.
Edit: I think that was just detecting full-on saccades but a microsaccade version would be smoother and harder to detect.
They’re looking to be increasingly more interesting as a biomarker for MS among other things [0]. There’s a lot we still don’t know about our visual systems and the advent of lower cost hardware is allowing huge amount of interesting questions to be hypothesized and tested. It’s a great time to be in the science behind all of this, like the authors at Brown on this paper!
I believe this might be available in less than 5 years, potentially less than 2, provided both http://www.adhawkmicrosystems.com/ and https://www.kura.tech/ ship and partner with each other. If either one of those companies dies or their technology doesn't work out like I hope, then it might be a while longer.
It depends on your application. If you're trying to replace your mouse with gaze, then yes you need careful calibration. I have worked on some purpose-built gaze interactive experiences and coarse accuracy without calibration can be enough to do something useful.
Just would like to see people be honest and admit that it was not only Trump that "put kids in cages" and there's entirely legitimate reasons to put kids in temporary holding while sorting out their immigration situation.
they don't have any power, only the current president. Claiming Obama did it, and Obama was Jesus, so it must have been good, sounds really strange coming from the group who claim Obama is the antichrist
The comment you replied to is asking “what happens to adopted children”. Strangely enough crossing the border legally doesn’t magically result in your adopted children getting new DNA. So claiming that “illegal immigrants” won’t put their children in that position is beyond stupid. The question is how does this impact legal immigrants.
This is sampling at actual border crossing. So all the actual families crossing are victimized in order to punish brown people. Because none of this is being done on the northern border, despite Canadians living illegally in the US generally taking higher paying jobs than migrant workers from Mexico and Central America
From the article: "DHS has repeatedly warned that children are being exploited by traffickers to skirt the nation's immigration laws."
So it seems to me that it has to do with people skirting the law and exploiting children, not to "punish brown people".
> Because none of this is being done on the northern border, despite Canadians living illegally in the US generally taking higher paying jobs than migrant workers from Mexico and Central America.
Have stats on the number of Candadian's crossing the border illegally each year? I'd bet its an order of magnitude less than our southern border.
> And then we get to the real crux: as numerous people have said, this incorrectly classifies normal families as not being families.
Which is a problem, but this should be used as a tool in conjunction with other records and interviews of the family crossing.
Think of it this way, if a family crosses with children, takes the DNA test and everything is confirmed then the process may go much faster as additional investigation would not be needed.
This is one area when the functionally can really be improved over what reddit implements. Having a moving window of time to sort within is an amazingly useful feature for sorting out trends or lost articles. The expanded granularity would be very much appreciated.
