nicholasjarnold··on ICANN proposes creating .INTERNAL domain to do the same job as 192.168.x.x
afaik the IANA is the body who is authoritative on this type of information. RFC1918[0] defines the address blocks reserved for private routing. From there it's up to various routers and their software to decide whether or not to actually flow the packets over their interfaces or not.

edit: I think I read the parent slightly incorrectly. I conflated TLD assignment with number assignment. Apologies.

nicholasjarnold··on Haier hits Home Assistant plugin dev with takedown notice
ZWave is another option here too. I wouldn't recommend devices that don't have at least a "500 series"[0] chipset, but pretty much any device you'd buy today or moving forward will contain this or a newer chipset.

nicholasjarnold··on Haier hits Home Assistant plugin dev with takedown notice
Shelly devices are great. They have a "cloud" that you can optionally use, but the settings (at least on the switchable plug and the in-wall energy-monitoring switches that I have) default to that cloud connectivity being OFF. They seem to be aligned with those of us who prefer local data, interoperability and despise vendor lock-in and surveillance capitalism.

I've been using Privacy.com for this "create single use credit card" for years now. They make money via the interchange fees, afaik, and not by selling your data stream.

nicholasjarnold··on IKEA sensors for doors and windows, motion, water leaks
Schlage makes some that use ZWave Plus (500 series or better, didn't check the spec sheet). I have an older model that works nicely for this.

This would give you the "is locked or not" capability you seek here, but obviously requires a replacement of your door lock (perhaps not trivial if renting, but is a very easy DIY otherwise).

I wasn't aware of the purported regulatory radio limits on power, but I can report anecdotally that I found a huge jump in usability/signal strength/ownership satisfaction when I started replacing my old ZWave 1 stuff with the 500-series or above hardware (ZWave "Plus" is the name for these sometimes).

This "LR" stuff you mention is what I think some are calling the Z-Wave 800 series. It more than doubles the radio range of the 500 series stuff and greatly reduces power draw for battery devices. However, I have 500 and 700 series sensors that only need a battery change once every ~2 years or so. I don't find that to be too much, and the signal strength has been no problem for me in an old brick house. I do have a handful of powered zwave devices around though, and these act automatically as repeaters for the other devices in the mesh.

As another sibling suggested you should seriously consider HomeAssistant here. A main selling point is it's ability to seamlessly integrate with an arbitrary mixture of Zigbee/ZWave/Matter/Kasa/<etc> devices under one management interface.

I've been running it for years, keeping up to date with the regular new versions, and haven't had any major complaints for basic use cases like: "I want to turn on <set of lights> when <arbitrary condition occurs> (e.g. sundown, certain sensors detect < X lux of light, wifi device is seen by access point based on its MAC). Super useful. Huge world of possibilities, limited only by your hardware and imagination.

nicholasjarnold··on Rivian software update bricks infotainment system, fix not obvious
Is it possible, as a licensee of the Rivian vehicle system, to disable the automatic OTA updates without having expert-level knowledge or tooling?

Also, yes, I'm specifically avoiding using the word "owner" above for obvious reasons.

nicholasjarnold··on Jury Finds Realtors Conspired, Awards Nearly $1.8B in Damages
I used an attorney specializing in real-estate to represent our side of the house during my first home purchase. We subsequently reduced the bid by 3% with an explicit note about why (no buyer's agent commission to pay). The seller's agent was a broker and was apparently motivated because they accepted our deal along with fixing a list of little items uncovered during inspection. We paid our lawyer a $2-3k iirc.

I'll never know if that broker got 6% from the seller or took 3% to close the deal, but our strategy worked: I paid 5 figures less for the home than what was being asked for at a time when houses were selling for over asking price in this area.

It's worth a shot I guess. 2 warnings: Some seller's agents will get very pissed at you (b/c this and other things like Redfin's 1% is disrupting their cash cow and they're not stoked about it). It might be difficult to find an attorney since most RE attorneys focus on commercial deals.

nicholasjarnold··on RIP to my 8-port Unifi switch after years and years of Texas outdoor temps
I want to _strongly_ second this. After seeing some Ubiquiti gear in use in various enterprise settings almost a decade ago I personally investigated the brand for home use and bought into some of the WiFi gear for use in conjunction with the rest of my network hardware/software.

If there were ever a requirement to allow public internet ingress or egress from this stuff directly I would immediately replace it. Self-hosting the controller is a base requirement for my use-cases as well.

nicholasjarnold··on Improving your online privacy: An update
Regarding usage of OpenStreetMap over Google Maps - assuming we're talking mobile usage - you might give OSMAnd[0] a try. I've been using it exclusively on a Pixel loaded with GrapheneOS for a few months now. I would never consider going back to GMaps and I don't feel that I've lost anything either.

nicholasjarnold··on Colorado kills law that made it harder for cities to offer Internet service
TING[0] is another company offering fast fiber in CO, but it's only been rolled out to limited areas right now. I'm in downtown Denver and enjoy 1 gigabit symmetric fiber for $70/month ('unlimited' bandwidth, no port restrictions, etc) through CenturyLink. The landscape is improving here gradually, and I'm as happy as anyone to be able to purchase a fat dumb pipe from not-Comcast.

nicholasjarnold··on America will soon see a wave of bank mergers?
Reasons other than "it helps me build a credit history":

* you think you can make more money by investing your 30k and letting it grow and compound

* you are very prudent with your cash on hand and would rather have immediate access to liquid cash than save a little bit on interest which you pay down over the course of <term>

Some of the dynamics here are a bit different when market returns are not looking great/steady and money isn't cheap anymore.

> Companies are already bloated, imagine when they realize one overworked highly paid senior can replace 10 juniors.

Yep. This is where I'm at in terms of personal armchair predictions of the future.

I expect the labor market will be tough for more junior software engineers in the coming years. This might indeed cause backpressure in the supply of new grads/new labor force entrants in this family of fields ("software development").

However, the "highly paid senior" is only around for so long before achieving financial independence and just not working anymore. Then what? The company didn't hire juniors because the "highly paid senior" did all the work. Whoops. Now the company lacks the pipeline of people to replace that senior.

It'll sort itself out in time, but the next decade will be interesting I think. Some companies will realize that they must make investments into the future of the labor force and will do better in the longer term. Other companies might indeed "fire the juniors" for some short term gains and find themselves lacking replacement staff later.

nicholasjarnold··on PFAS can suppress white blood cells’ ability to destroy invaders
Ah! Yes. Thank you. One thing I didn't mention is that I've seen this described by pro cooks like "you know when the pan is hot enough when water droplets don't merely boil off quickly, but instead dance around rapidly in the pan". Leidenfrost! TIL

> “Oh boo hoo I have to scrub my stainless steel pan a little harder cause I don’t have a Teflon pan any more.”

Stainless steel, while typically being derided by many home cooks for being "hard to clean", is actually quite pleasant to work with if used properly. What does that mean? Well, I've discovered that it means you should start with high quality pan (I use All-Clad BD5 and Copper Core, though there are many other good options too), heat it up fully before adding anything to it, throw in some fat and wait a few seconds for it to heat sufficiently, then add your food. Keep the heat up while cooking (good pans help with this part a lot).

Try it and thank me later. It changed my life. :)

nicholasjarnold··on Big Tech is using layoffs to crush worker power
To add a counterpoint - I've heard senior executives remark about the likelihood that many of those let go are the not the employees that you really _want_ to pickup. The reasoning they've implied there is that these big companies that hire so voraciously have simply made some mistakes along the way and used the current happenings to jettison those mistakenly-hired employees swiftly and efficiently.

Note: I'm sure many very talented people were caught up in this tide, too. I'm just relaying some anecdotal opinions that I've heard from hiring managers and execs in my personal and professional circles.

nicholasjarnold··on A Fix-It-Yourself Trend for Appliances (1983)
Same. This website is a great resource. I fully disassembled my (less than 7 years old!) Samsung front-load dryer to replace the drum belt at one point and the heating coil at another point by using this website and it's videos. Much easier and cheaper (yes, I do value my time...didn't take long) than having to find a repair person, schedule a house call, etc etc... I just busted out a couple common tools and did it myself. Highly recommended for DIY repair.
nicholasjarnold··on Microsoft Transitions U.S. FTEs to “Discretionary Time Off”
Yes, I recall reading the same thing many years ago too. IIRC the results were specific to the United States and it was posited that this might be due to differences in US employees views towards work. We tend to overwork ourselves whereas some of our EU or non-US counterparts don't do that as much.
nicholasjarnold··on Ask HN: Developers, how do you deal with socials, blogging, etc
Same! I've been paid to produce and deploy software solutions for maybe slightly less time than you (under 20 years, more than 15). I technically still have a Twitter account that I literally never login to or interact with in any way. I have zero "social" apps on my rooted phone. I dumped Facebook after grad school. I never opened any insta, tiktok, etc. I do not blog. I do not post weird updates on LinkedIn either. I basically opted out of the entire "digital social" thing altogether. People who are important to me know how to contact me. I don't feel any need to "have a presence" in the digital social sphere, outside of leaving my thoughts here sometimes (because I respect this site, how it operates and it's community)...and because it hardly feels like typical "social" stuff we see today.

So, I guess my point is that like you I've found that it doesn't really seem to matter to my career, my compensation or my ability to be happy or feel connected to others. You're in good company. Cheers!

nicholasjarnold··on Salesforce will lay off 10% of staff as part of restructuring
Good point. I should have scoped my comment to only target projects which primarily require software engineering.
nicholasjarnold··on Salesforce will lay off 10% of staff as part of restructuring
When this collapse in workforce population occurs perhaps firms will learn that they can survive and even thrive with much less "fluff staff" who mostly sit idle or contribute very little to the overall success of any given project. I continuously see a decent amount of what I consider staffing excess in a large fraction of the companies I've worked with. (My personal philosophy here is that companies/projects/etc are better off with fewer and much higher quality employees. The challenge is finding them, hiring them and keeping them.)

It's been echoed here often that many of the large SV firms and MAANG-type companies were just hoovering up talent to keep them away from competitors. This seems like a decent corp strategy when cheap money is raining down for 1-2 decades. However, now that we're entering into a new macro-economic climate maybe this practice will subside a bit, too.

nicholasjarnold··on Tell HN: Your Android carrier can remotely turn settings on
> I must say I strongly dislike losing control over my own device. It feels dystopian to me.

Even with a rooted device where perhaps you personally coded up the ROM you are still missing a piece which is the binary blob that runs the baseband radio. That firmware is, afaik, not something which exists in any sort of open-source or rootable manner. It's a closed blob running proprietary software on your phone, and it runs at a lower level than the ROM/OS does. So, even if you go to great lengths to secure most of the software that runs on the device (a noble goal, it's your hardware after all!) then you still must contend with the uncertainty and perhaps risk (depending on your threat model) of that untrusted code running there. You can search around the web for articles covering baseband radio exploits that span the years...
