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

<p>Fantastic write up. It's mind blowing how much complexity there is to keep flights going day in and day out.<p>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.<p>Cool looking at the pictures of the dashboards. It's nutty to think how much has to be tracked when doing airplane maintenance.</p>

<p>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?<p>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.</p>

It's in Your Electric Bill [video]"]]></title><description><![CDATA[
<p>Great video on how the public is getting screwed on energy deals.<p>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 first problem. All that needs to be out in the open.<p>What really irks me is that the market is so manipulated that we can't do anything about it. Think about NEM 3.0 vs 2.0. Putting data centers in their own rate class does make sense as the first step.</p>

<p>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 <a href="https://github.com/openmiko/openmiko" rel="nofollow">https://github.com/openmiko/openmiko</a><p>That said it's really hard to make long term supportable open source camera software/firmware. And when picking cameras it is even harder because the market as it stands now does not let you have it all. You need to pick what facets you really care about.<p>Also keep in mind even the above code is not really opensource all the way: I still had to load the driver binaries. Not sure that source will ever be released. The kernel is also old as heck.<p>What I do feel good about though is saving these old cameras from the dumpster if Wyze ever stops supporting them. The firmware works for simple cases: just load it up and you can start curl'ing frames. I used it in scripts to put together timelapse videos with ffmpeg. No need to screw around with authentication, phones apps, email, etc.</p>

<p>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.<p>Lots of ads. I might be old school but I still hold quality to something like anandtech back in the day. Something that a real human spent time on because they were genuinely interested in the topic and decided to write about it. The bar is so low these days not sure if there even is a bar.<p>This site is suppose to be a men's lifestyle magazine but it barely has any content that isn't just filler and fluff.</p>

<p>It's so dumb to assign it a CVSS score of 10.<p>Unless you are blindly accepting parquet formatted files this really doesn't seem that bad.<p>A vulnerability in parsing images, xml, json, html, css would be way more detrimental.<p>I can't think of many services that accept parquet files directly. And of those usually you are calling it directly via a backend service.</p>
