bravo22 commented on FDA recalls defective iOS app that injured over 200 insulin pump users   theverge.com/2024/5/9/241... · Posted by u/belter

The “substantially equivalent” approval loophole is a textbook example of regulatory capture:

- approvals for version N + 1 are basically skipped, as is safety testing

- manufacturers get a liability shield

- for many classes of devices, ladder pulling implies that no one will ever get another v1 approved. (The current rules for that are impossible to meet, but the incumbent company is grandfathered in under the old rules).

The testing is NOT skipped. This is a misunderstanding of 510(k).

The device still has to go through testing, validation and verification. It is a very detailed process and follows IEC spec. The device also needs IEC 60601 testing by a third party lab. In this case at least 60601-2-24.

The 510(k) means it is not doing something new therapeutically therefore it doesn't need to go through PMA process which so much longer and more complex. In this instance they're saying a pump that uses electronics to monitor and deliver glucose already exists. Our device does the same thing therapeutically but we do it differently and here is all out docs showing the device is safe.

If they came up with a magical patch that used quantum chemtrail energy to align the shakras and thereby affect the patient's insulin levels, then they would need to go through PMA and show the therapy is safe and works in small clinical trials followed by larger trials before they can make a device that can be marketed.

> Liability still exists in a free market

Only if a wronged party has the resources (time, money, political capital) to pursue it.

Which is but one reason why it is deeply silly to rely on it to make a society go.

Don't forget the resources and money required to bring X to the limited attention of the regulators and to ensure the regulation is sufficiently up to date and not subject to capture. I would argue it is orders of magnitude more than exploring the same through liability.

And putting resources towards lowering that barrier would go significantly further than any regulation.

Regulation is by nature slow and highly susceptible to corruption or stagnation. Whereas the courts, as onerous as they may be, essentially achieve the same thing through liability but it is more dynamic, more responsive, and more likely to error correct than the former.

In free market it's also OK to cut costs as much as possible, making chair that explode and kill the user one day after the warranty expires.

That's why we have regulation: to establish the minimum standards.

Simple medical devices like wheelchairs (Class I or Class II) are also not super over-regulated, you don't need to do clinical trials to certify them. All-in-all it'll cost you around $10m, which is not at all a moat.

Liability still exists in a free market. Regulations are government's way of giving you immunity from liability laws, or not enacting them, in exchange for doing things a very specific ways. This creates moates.
bravo22 commented on Nikon to acquire RED   nikon.com/company/news/20... · Posted by u/gaoryrt
7moritz7 · 2 years ago
Am I reading this right in that Red has somehow managed to patent the idea of compressing 4K RAW footage on device which holds up the whole industry?
bravo22 · 2 years ago
Not quite. The claims, in the only one I've seen regarding RAW compression, are for a specific pre-emphasis curve being applied to the raw data, then the raw data being compressed and only cover this being done in a video camera.

When looking at a patent check the "Claims" section. An infringing device would have to perform those steps in the order provided for the patent holder to have a claim.

Disclaimer: I am not a lawyer, but I've had a lot of dealing with patents.

bravo22 commented on SanDisk Extreme Pro failures result from design flaw, says researcher   tomshardware.com/news/san... · Posted by u/dangle1
nrp · 2 years ago
These SSDs are tiny. The controllers can easily get up to 80C during sustained writes, so there could be mechanical stress from thermal cycling. (Source: we also make small USB-interfaced high-speed storage devices and do a range of reliability testing for stuff like this)
bravo22 · 2 years ago
On the SSD chip sure. This looks like a resistor on the data line. The resistor would certainly not get to reflow temp.

> On the one hand, the resistors used in these SSDs are too big for the circuit board, causing weak connections

I am an electronics / PCB hobbyist and I can't for the life of me figure out how they came to such a weird conclusion. What does this even mean?

Larger components will have more surface area at the joint and should be stronger than a smaller component

> On the other hand, the soldering material used to attach these resistors is prone to forming bubbles and breaking easily, according to Häfele.

Never heard of solder doing this - it seems more likely to me that the solder wasn't reflowed properly in manufacturing.

What's more is that the component pictured is a capacitor.

The only conclusion I can draw here is that the guy has no clue what he's talking about

bravo22 · 2 years ago
The most charitable way I can read their statement is that the resistors are too large for the pad, and along with poor solder material it forms a weak joint which breaks over time.

I have a hard time accepting that because there is not a lot of heat on that line nor is there a lot of physical stress, like constant vibration on SSDs.

Unfortunately HDMI audio is also notorious for often having serious lag, both in absolute terms and relative to the video signal.
bravo22 · 2 years ago
The issue is not with HDMI. The audio data is sent between each frame. The lag comes from the fact that TVs apply post-processing to video which causes it to lag relative to audio.

(Being serious) should banks as we know them even exist, then? Maybe having them fill a role as an intermediary makes sense, but now that we can securitize loans, why does opaquely connecting short-term lenders directly with long-term borrowers make sense?
bravo22 · 3 years ago
I am going to assume that you are OK with fractional reserve banking so I won't talk about why that is necessary as a function in an economy.

If I understand you correctly, you're basically saying why use a bank versus something else? My answer would be because for vast majority of retail bankers it doesn't matter. Same reason many would use Gmail vs self-host. They want to put their money somewhere and ensure that it will be there when they need it. As a society we have a framework around that and we provide deposit insurance and we call the orgs who take your deposit, give you an IOU (in the form of an account balance) then lend a fraction of it to others a bank.

For significantly larger sums no I don't think it makes sense to use a bank and most large corps have a treasury that specifically deals with that.

In some ways, money market funds are safer than banks because they're not playing the borrow short lend long game. The risk of getting wiped out is also lower, though the risk of getting 95 cents on the dollar is higher.
bravo22 · 3 years ago
Which is what businesses should have used instead of putting hundred of millions in a bank. Banks can't magically change economics. Money markets were created exactly for this purpose. This should have been taught to every founder by every VC.
