  • The article title is misleading, but the research is interesting. Essentially it’s saying that when the rocket self-destructed due to it performing off nominal (as the first test ever of this vehicle) it ionized a large swath of the ionosphere from Mexico to the SE US which can impact the accuracy of GPS for systems that require high precision. The ionosphere reionizes very quickly naturally though so the effects are short lived (hours to maybe a day) and the impact to navigation at least should be small because of how GNSS works with built in corrections for exactly these types of errors. It feels like Nature is stretching a bit with the doom and gloom headline that the authors don’t even point to in the article (though I have not read the paper to be fair).



  • From my reading this is misleading at best and likely wrong. I don’t work with CrowdStrike Falcon but have installed and maintained very similar EDR tools in enterprise environments and the channel updates referenced are the modern version of definition updates for a classic AV engine. Being up to date is the entire point and so typically there are only global options to either grab those updates from the vendor or host them internally on a central server but you wouldn’t want to slow roll or stage those updates since that fundamentally reduces the protection from zero days and novel attacks that the product is specifically there to detect and stop. These are not engine updates in that they don’t change the code that is running, they give the code new information about what an attack will look like to allow it to detect malicious activity as soon as CrowdStrike knows what the IoCs look like.

    In this case it appears that one of these updates pointed to a bad memory location which caused the engine to crash the OS, but it wasn’t a code update that did it (like a software patch). That should have been caught in QA checks prior to the channel update being pushed out, but it’s in CrowdStrikes interest to push these updates to all of their customers PCs as quickly as they can to allow detection of novel attacks.


  • For me as the driver of not one of these cars, I think the driver monitoring and sheeting is perhaps one of the most important parts of these systems. I 100% want your car to scream at you for not paying attention while use the driver assist features because it’s such a common and easy thing to do (if it works 99 times without issues, human nature is to assume it will work that 100th time, so checking that email from work real quick is probably fine). When the consequences of a driver failing to post attention while using these systems is potentially other people dying in a horrific crash, your discomfort at an alert because you happen to be a perfect driver that never does other things in the car while driving doesn’t matter.


  • Trees and scratchers are a must, cats usually scratch furniture because there isn’t something else nearby to use. Trees give them a place to climb and feel safe up away from things. You should also have places for them to hide (boxes, piles of blankets, a bed in a quiet room, etc). As for toys, it really depends on the cat. Ours is super picky and only likes specific rattle balls from Amazon, small rattle mice, and some kickers (there are few others but they are all small and easy for her to cray around). But for every one toy we found she likes we have half a dozen she won’t touch. You’ll likely need to try a bunch to find what yours will enjoy.



  • I say wear what you like when it comes to underwear. If you want to wear full long Johns under your pants then don’t let anyone stop you, and the same goes for thongs, tighty whities, boxers, and everything in between. In th ink what major brands are realizing is there is an untapped market for additional styles and men are comfortable enough to at least try them. Companies like cocksox have made actual men’s thongs for years, amongst many other styles (actual meaning designed for all day wear, not just a night in with a significant other). That is to say it was possible to find them for a bit if you looked, it’s just more recently that you don’t really have to look to find them in places which I think means they are more than just a fad.


  • A lot of these depend on the model and where it’s installed (geographically and within the house). In many areas of the US, there is a drain in the floor near all water heaters as a matter of code, you can drain condensate directly to that (and unlike gas appliances, the condensate is clean and does not need treated to go in household drains). I honestly think the noise concern is hugely overblown and used as an excuse for people that don’t like change. Sure it exists, but if your water heater is in the basement or garage like the majority are at least in my areas of the US, you’ll never notice it. I also look at the cooling air as a benefit for at least half the year, I can close all the vents in our basement for the whole spring/summer and it’s super comfortable. In the winter it’s a tad chilly, but not uncomfortable. Drying the air is also great for our basement, it’s literally a dehumidifier in what’s usually a pretty damp location for many people. Ours (a rheem unit) has a flimsy plastic air filter you vaccuum off once a year as well so not really a huge deal. I think most are like this.

    I agree that folks should do their homework and understand what they are getting. Heat pump water heaters are great, but are overpriced at the moment. Even with electric company rebates and a tax credit it cost more than a decent gas replacement would for us. It’s likely to only pay off because we have solar and so don’t really pay for electricity for a large chunk of the year. But I expect costs to come down over the next 5-10 years as these become the go to for most electric installs (and with fewer new gas hookups in new and renovated buildings that’s like to be most installs). Once these hit that $700-$1000 price point there’s really no good reason most people shouldn’t default to installing one.



  • YMMV of course, and will highly depend on how many people are in your house and how you use hot water, but a 50 gallon heat pump water heater easily supplies a dishwasher and two long showers with 1/3 of a tank of available water left in our house (and I take pretty hot showers that are not always as short as they should be). Sure, it takes an hour or two to fully recover but we aren’t ever looking to use much more hot water at one time. If you have a household of four, it may be a bit more of a problem, but then you can easily schedule other hot water uses to happen “off peak” like a dishwasher.


  • Idk, I DIY swapped out old gas water heater for an electric heat pump water heater heater and it was super straight forward. If you have the plumbing and electrical skills to add a circuit and move your hookups (since on most gas water heaters they are on top and most heat pump water heaters they are on the sides top and bottom), you probably have the skills to safely disconnect and cap off the old gas line. Just be sure to use pipe dope that is rated for gas, and check with soapy water once you pressurize the line again for leaks.



  • Asking broadly like this is akin to asking for a guide on how to cook, it’s generally too broad for there to be a single guide. You first need to figure out what your goals are (you state one already, you’d like it to be externally accessible), determine what services you want to host, and then start looking at how to do so.

    The advice I’d give is to start with a solid base, you’ll need something to self host on and it really shouldn’t be the PC you use for other things. Get it setup to run a virtualization OS such as proxmox and use that as your starting point. Then do a lot of reading. I spend probably three to four times as much time reading about the service I’m planning to deploy compared to actually doing the work to deploy it. Lastly, plan. You should have a solid plan in the beginning of how you want your service to work (what will be external vice internal only, how will you setup the networking stack to do that, are you going to have a domain, and will you use subdomains or folders to divide services, what does your IP space look like, will you host your own firewall to make the networking more controlled or fight with your ISPs router, do you want to use docker, kubernetes, or maybe full VMs for each service, do you want/need a UI to manage things from or are you comfortable with CLI, etc). These answers will lead you to guides for various services as well as service specific forums where help is more focused.




  • This is pretty much it, Plex offers far more client apps that are full featured and they make it super easy to setup and use both as an admin and a user. Especially for things like OTA TV where they provide the guide data once it’s setup (which is why it’s a paid option). I’d move to JellyFin in a heartbeat if they’d support OTA and DVR playback on AppleTV.



  • In most companies I’ve worked for, T1 is there to put in tickets from calls, and handle the simplest of tasks (password resets, account lockouts, “have you tried turning it off and on again” tasks). Anything beyond that is generally sent to T2 (usually the desktop team who then force other teams to accept tickets as needed) and T3 for anything that more systemic or needs deeper troubleshooting and system knowledge.

    In many places it’s a combination of piss poor pay creating little motivation and high turnover (and thus lack of training) and management prioritizing the wrong metrics (generally looking for short call times and short call queues). If you want to try and improve things I’d suggest learning about the KPIs that team is expected to meet, and then ask management why they chose those metrics. Generally I’ve found prioritizing first call resolution over call times to be a huge improvement to motivation of the team and user satisfaction scores (we all like solving problems and users tend to be way nicer when you fix the issue vice kick the can).

    I would say, at least to your point about them not having access to systems, that’s it’s very common for T1 to have pretty limited admin access to systems. Partly to protect against inexperience, but also as a social engineering protection. If they need to ask for access to pass a ticket for elevated rights, it gets another set of eyes on the call to ensure it’s all kosher.



  • Honestly I don’t really know. I don’t think it has to be but you’ll need to research what kind of certs you’ll need for your purposes and what options exists for a CA.

    My overall point was more that this isn’t really a “just setup Apache” web service, it’s a fair bit more involved since your looking for (I’m assuming) legally valid digital signatures which means they need to be secure, unique, identifiable, and adhere to non-repudiation. Services like DocuSign do all of that work already so unless you truly want open source because of passion or principles, this isn’t really a great area to try and roll your own without some experience and expertise.
