Southwest airlines had a culture of turning around fast at the gate. So maybe no explicit policy but culture can drive unintended consequences and decisions.

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

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 w

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.

Great video on how the public is getting screwed on energy deals. Basically large tech companies have the deep pockets to push up prices at electricity auctions. But why bid in public when you can do those deals in private. That's the

A number of years back I got bored during covid and decided to reverse engineer as much of the Wyze Cam V2 camera I could and make some custom firmware for it. Right now that lives at https://github.com/openmiko/openmik

So basically you trust something because you have a long chain of assurances that you trusted it before? Kinda like certificate pinning.

Visiting the site it is easy to see why they got demoted. It's all fluff and no substance. Almost all the links I clicked through could have been generated by a LLM. Lots of ads. I might be old school but I still hold quality to someth

I love it. Could definitely see more features where you can see the results of the jury questions.

It's so dumb to assign it a CVSS score of 10. Unless you are blindly accepting parquet formatted files this really doesn't seem that bad. A vulnerability in parsing images, xml, json, html, css would be way more detrimental. I can

Thank you for providing this. He mentions right after that "empathy is good but you need to think it through and not just be programmed like a robot". That quote is clearly taken out of context and is specifically chosen as click&

Funny how this popped up as I was just talking to a friend about some of the challenges I've had with logging. Would definitely be interested in contributing to a project like this. Hit me up (email in profile).

Is the documentation for AI chat bots or for humans? The PR is now closed but seems like we should be striving to do better.

Such a great story. Something like this could have only been pulled off in that era.

Are you saying you think the Canadian government should pay more toward fertility and less toward LGBTQ procedures such as gender reassignment? I wonder how much money the latter costs. Seems like it wouldn't be as big a cost vs fertil

What switches enterprise or consumer tend to support this LLDP? My guess is maybe almost none on the consumer side. I.e. Netgear, to link. Cisco probably does. How about ubiquti?

Long term this is good for the software ecosystem as a whole. Especially open source options like proxmox. I think Broadcom is making a strategic business mistake not willing to negotiate in good faith. However this is the true cost of usi

So this basically means to scan for this exploit remotely we'd need the private key of the attacker which we don't have. Only other option is to run detection scripts locally. Yikes.

For me it's basically summed up as "we didn't test turning the power off" and making sure things worked the way we planned. Yes it is hard and very expensive to do these types of tests. And doing it regularly is even mor

I don't think the issue is bad accounting. I think it comes down to software being uniquely different than a factory or piece of equipment. Amortization schedules that are even don't make any sense. Neither does anything measure i
