• ⁨Comment⁩ on ⁨Why do cell phones have a data limit but home internet doesn't?⁩ ⁨⁨4⁩ ⁨weeks⁩ ago⁩:

  In theory at least it’s because you pay for a specific bandwidth for home internet (the size of the pipe) but a specific amount of data for cellular (how much stuff you can get through a fixed sized pipe).

  Home internet is a little unique in that way, almost all other utilities are consumption based with no real tiers in terms of how it’s delivered (you pay for the volume of water or gas you use, electricity is the same, just different units).

  Networking equipment gets more expensive based on the bandwidth it supports, but it doesn’t much care how many bits you push through it. So ISPs charge based on their capacity to deliver those bits, and provide tiers at different price points. Cellular though is much more bandwidth constrained due to the technologies (and it used to be much more so before LTE and 5G), so it didn’t makes sense to charge you for slow or slower tiers. Instead the limiting factor is the capacity of a tower so by limiting data to small amounts it naturally discourages use. That model carried forward even now that the technologies support broadband speeds in some cases. As such and ISP could provide the biggest pipe (highest speed) to all homes and just charge based on consumption (they used to in the days of dial up, and satellite before starlink always has). Many ISPs instead are now double dipping though and charging for both.

  Looks from the article like it was stolen by infecting the PC of a third party analytics firm user who had privileged access to Hot Topics snowflake data warehouses and didn’t have MFA enabled. That is just inexcusable in this day and age and $100k is a small price for Hot Topics snowflake to pay for that fuck up (assuming the bad actor actually follows through and doesn’t sell the data if HT pays the price set). Pro tip (or really amateur tip), MFA all the things. Even SMS based MFA is better than no MFA even though it’s not ideal.

• ⁨Comment⁩ on ⁨Huge SpaceX rocket explosion shredded the upper atmosphere⁩ ⁨⁨2⁩ ⁨months⁩ ago⁩:

  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).

• ⁨Comment⁩ on ⁨CrowdStrike’s faulty update crashed 8.5 million Windows devices, says Microsoft⁩ ⁨⁨4⁩ ⁨months⁩ ago⁩:

  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.

• ⁨Comment⁩ on ⁨A top auto safety group tested 14 partial automated systems — only one passed⁩ ⁨⁨8⁩ ⁨months⁩ ago⁩:

  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.

  Please keep in mind that you need to seal that print before you use it with food. Because of the layers, there’s are a ton of places for dirt and bacteria to hide that are impossible to clean. Additionally, depending on what kind of nozzle you used, heavy metals can end up in your print which you don’t want to then leech into your coffee. General advice is to just not use 3d prints first good, but if you really want to you should coat them in a food safe epoxy before using.

• ⁨Comment⁩ on ⁨Heat-pump water heaters are a winner for the climate — and your wallet⁩ ⁨⁨11⁩ ⁨months⁩ ago⁩:

  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.

  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.

• ⁨Comment⁩ on ⁨Heat-pump water heaters are a winner for the climate — and your wallet⁩ ⁨⁨11⁩ ⁨months⁩ ago⁩:

  They almost always have two high wattage resistive elements installed like a traditional electric water heater which require the 220v/30a circuit. The compressor runs on 220v but sips almost no real current while running.

• ⁨Comment⁩ on ⁨Heat-pump water heaters are a winner for the climate — and your wallet⁩ ⁨⁨11⁩ ⁨months⁩ ago⁩:

  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.

• ⁨Comment⁩ on ⁨Heat-pump water heaters are a winner for the climate — and your wallet⁩ ⁨⁨11⁩ ⁨months⁩ ago⁩:

  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.

• ⁨Comment⁩ on ⁨For folks who write for Medium.com, what's your engagement like, and how much do you make?⁩ ⁨⁨1⁩ ⁨year⁩ ago⁩:

  Or you can use something like Squarespace or Wix and have a fully functioning website with everything you need in a few hours and start monetizing your views with ads. Both start at $16 a month so it’s a larger hill to climb sure but you get custom branding and don’t have to deal with the baggage of a Medium page (largely that it’s considered in many circles an untrustworthy source for pretty much any topic mainly because of how easy and barrier free it is to write there. They also have a pretty well established history of working to screw over contributors to profit off of your work including you automatically giving a full license to medium for everything you post).

  If all you want is a newsletter though without a webpage to back it you can setup something in mailchimp with a custom domain (.coms start at about $10 from cloudflare). Again an hour or so of reading and configuring and you’re on your way, with an Adsense account you can even embed inline ads to your newsletter.

• ⁨Comment⁩ on ⁨The complete guide to building your personal self hosted server for streaming and ad-blocking powered by Plex, Jellyfin, Adguard Home and Docker.⁩ ⁨⁨1⁩ ⁨year⁩ ago⁩:

  I would recommend prowlarr instead of jackett for indexer management, and pihole as at least an additional blocking service but in reality it’s really all you need for use at home. I’d also strongly encourage use of a VPN on your *arr download services. I use a separate box to run Plex and then have my *arrs all running on their own VM inside if it to provide separation and allow be to more easily segregate the network traffic (as someone that doesn’t really know docker that well it “just works” for me. Also probably worth looking at how to store your media on an external target, it’s easy to quickly accumulate 10s of TBs of media and trying to store that all on the server locally is asking for trouble. Better to set everything up on a NAS to start.

• ⁨Comment⁩ on ⁨Where to find guide on self hosting for a complete beginner?⁩ ⁨⁨1⁩ ⁨year⁩ ago⁩:

  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.

  I use protonmail with their family plan, it’s not terribly priced when you consider it comes with calendar, vpn, and drive storage as well. The biggest annoyance is probably that you have to use their mobile apps due to the encryption and they are not the greatest, but it does encrypt everything which I find outweighs the forced use of just their app.

• ⁨Comment⁩ on ⁨Siding, Insulation, or Mini-Split?⁩ ⁨⁨1⁩ ⁨year⁩ ago⁩:

  You want to insulate first, otherwise anything else you do is just going to be pushing heat through your exterior walls. You should be able to get spray in insulation in those walls without needing to full tear down the drywall. Typically you’ll get a 1-2” hole on the top and bottom of each stud bay for foam to be sprayed in, then you patch that. It can be pricy up front but should pay off super quick if you have none right now (I’m still getting over 3,000 kWh… that just seems like an insane amount of electricity to use).

  A mini split likely won’t help, you’ll just lose the cooling without insulation the same as without the mini split. You may want to look into balancing your ducting once you get the house insulated if you still have rooms that are too hot or cold. The bricks should help to stabilize temps and reduce swings over time but the effect is likely small and should be able to be ignored once you insulate.

• ⁨Comment⁩ on ⁨Interior Door Question⁩ ⁨⁨1⁩ ⁨year⁩ ago⁩:

  Not all modern furnaces and water heaters pull in outside air. Less expensive gas furnaces may still use interior air for combustion and almost all gas water heaters will. Heat pump water heaters absolutely need ventilation to work correctly as well.
