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 l…

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 …

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 …

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 infrastructu…

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 pub…

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…

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

Is the send function considered non-blocking?

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…

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, js…

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 o…

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…

This is using elixir right?

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 c…

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 ne…

> The July 2022 outage was not the result of a design flaw in the Rogers core network architecture. Talk about some grade A gaslighting here. Reading the post mortem they first tel…

If you take a look here you can see how this type of tiering system works out: https://usa.visa.com/content/dam/VCOM/download/merchants/vis... Some of the tiers for Visa cards: Vis…
