Article mentions the passwords were hashed with sha256 plus a salt. For a long password more than say 12 characters this would take a very long time to brute force. My guess is a lot of these were dictionary attacks ?

Confused as to the actual root cause. Don't all hard drives provide SMART diagnostics these days? Was it really bad sectors?

Fantastic write up. It's mind blowing how much complexity there is to keep flights going day in and day out.

My guess is all airline NOCs operate 24/7 as flights happen around the clock. Also planes typically don't have much downtime as that loses money so everything has to be a continuous operation.

Cool looking at the pictures of the dashboards. It's nutty to think how much has to be tracked when doing airplane maintenance.

Correct me if I am wrong but I thought the primary appeal of LoRa was range? Also isn't the primary factor in making long range radio go through things is the frequency? So 2.4ghz is the same frequency as consumer wifi right and thus would propagate about the same right?

It doesn't seem like this would be that useful except that the protocol is LoRa so you can have higher bandwidth between two devices if they happen to be close enough together.

How does the app read the variable if it can't be read after you input it? Or do they mean you can't view it after providing the variable value to the UI?

I remember reading slashdot but what is their system? Is there a separate set of mods that moderate the moderators?

How is this mode not a standard part of their disaster recovery plan? Especially in sf and the bay area they need to assume an earthquake is going to take out a lot of infrastructure. Did they not take into account this would happen?

Fundamentally is there anything you can't write in rust and must write in C? With AI languages should mostly be transposable even though right now they are not.

I can feel my blood boiling for you. In fact I'm in the market for a new phone and stories like this make me actively want to avoid Samsung. As companies get larger and larger they will tend to make choices that are suboptimal to consumers.

Cynical me says that Samsung is seeing above average warranty claims on these foldable phones. Thus they need to get them down so some manager somewhere decides that they will enforce the policies more strictly with small scratches and dents outright disqualifying claims. Lo and behold this reduces the warranty claims paid out but in the grand scheme of things completely demolishes any customer loyalty.

I wonder if author reached out via twitter or some other social media channel to have Samsung comment.

Also I have to think what Apple or Google would do. I'm pretty sure Apple would just straight up repair the phone with very few questions (that has been my experience). Google you'd have to go through a longer warranty process but my guess is they'd be more lenient and eventually you'd get a new or repaired phone.

Samsung is losing hard here.

Stephen Hawking defined an entire generation. Say what you will but he created a culture far beyond that of just a physicist. He was both parodied and revered.

I don't think that is broken. The algorithm is sound conceptually. I was almost looking for some type of theory where all mergesorts and binary searches could be improved.
