Watching a good friend of mine struggle with this after diagnosis for a few years now and I feel this really captures the nuance and complexity of this struggle well. Stimulants are an incredible tool but also an incredibly imperfect one.
I’ve heard that if you have a solar system and a battery system connected to the grid, if the grid goes out for whatever reason, your battery gets cut off as well. Meaning that it’s essentially useless as power backup.
Is this true? Can you really go fully off-grid in Australia?
I’ve heard this from rural people in Victoria, where they do experience blackouts and where an actual backup would be useful.
Many systems, especially older ones, are set up this way by default.
But you can get, for extra $$, a switch to disconnect you from the grid entirely when it's down and run from your own solar power / battery. People who live in cities with underground wires normally don't bother, but it's essential in the countryside (IMHO).
Note however that many people have only maybe 5kW or 8kW or something like that being added to grid power by their solar setup, so if there is no mains power then it doesn't take many 2kW appliances (microwave, kettle, clothes washer (when heating water), dish washer (ditto), hairdryer, vacuum cleaner) to overload it. Not to mention 3kW hot water heater or 3kW+ stove oven.
I have a 3600W off-grid system (Pecron E3600LFP) and I run pretty much all that stuff from it. I added up and I could try to turn on 14kW of stuff at the same time. But I don't, obviously.
It depends on the inverter. Older "grid-following" inverters would isolate themselves from the grid to avoid putting any current on the line when presumably in an outage it should be de-energised, as well as relying on the grid for reference frequency.
Modern hybrid & multi-mode inverters are capable of isolating themselves from the grid, generating their own reference frequency and managing connection and disconnection from the grid. However you might not get one of these types of inverters unless you specifically ask for "backup power" or similar.
I've had solar for ten years and just added a battery to it which _should_ keep the house running through a power failure for as long as the battery holds out.
This is yet to be tested, but it's very specifically setup to me able to.
There are some specific electronics required to continue operation when the grid is down, and with the explosion of popularity of home batteries, I think these options are also more common.
you heard wrong. What most electricity grids forbid is exporting power from your home to the grid when the grid is down. The claimed danger is that energised power lines will kill people working on the lines.
The reality is that the vast majority of home inverters (in an EV, battery or solar PV) is nowhere near powerful enough to energise even a single distribution transformer.
This is yet another example of electricity codes being unrealistically restrictive.
Generally, there's nothing stopping you from disconnecting your home from the grid during a power outage and running your own devices off a battery. Going fully off-grid depends on your local laws.
I’m not sure about that, I mean this is something that client-side prediction in games is doing all the time, so why wouldn’t a self-driving car do it?
I sleep in what would be considered a relatively large master bedroom with ensuite. Recently got an AirGradient One sensor and was shocked at the overnight co2 levels.
When sleeping with window and door closed and just by myself, co2 levels exceeded 2,000ppm by morning and only fell once I was awake and opening doors.
With the window slightly open and the door slightly open, levels were at a much better 700ppm or so.
If this thing works as advertised, that would be great. There are a lot of situations where it’s difficult to sleep with the window or the door open.
I configured my furnace to always recirculate air in the house even when burner itself is off - helps to avoid rooms with stale air and evens temperature through the house.
Your HVAC is supposed to recirculate the air using the fan feature. And you don't even need to run it 24/7; I find that running it for a few minutes each hour is enough to get CO2 levels down.
Alright so two CPUs failing in the same system has gotta be strange; mobo issue?
Secondly, what BIOS settings should I be using to run safely? Is XMP/whatever the AMD equivalent is safe? If I don't run XMP then my RAM runs at way below spec (for the stick) default speeds.
XMP is technically overclocking, nothing inherently safe about it. I've had new dual channel kits fail memtest at XMP settings on Ryzen, it seemed to depend almost entirely on what the individual CPUs memory controller was capable of.
I primarily work in C# during the day but have been messing around with simple Android TV dev on occasion at night.
I’ve been blown away sometimes at what Copilot puts out in the context of C#, but using ChatGPT (paid) to get me started on an Android app - totally different experience.
Stuff like giving me code that’s using a mix of different APIs and sometimes just totally non-existent methods.
With Copilot I find sometimes it’s brilliant but it’s so random as to when that will be it seems.
> Stuff like giving me code that’s using a mix of different APIs and sometimes just totally non-existent methods.
That has been my experience as well. We can control the surprising pick of APIs with basic prompt files that clarify what and how to use in your project. However, when using less-than-popular tools whose source code is not available, the hallucinations are unbearable and a complete waste of time.
The lesson to be learned is that LLMs depend heavily on their training set, and in a simplistic way they at best only interpolate between the data they were fed. If a LLM is not trained with a corpus covering a specific domain them you can't expect usable results from it.
This brings up some unintended consequences. Companies like Microsoft will be able to create incentives to use their tech stack by training their LLMs with a very thorough and complete corpus on how to use their technologies. If Copilot does miracles outputting .NET whereas Java is unusable, developers have one more reason to adopt .NET to lower their cost of delivering and maintaining software.
That's the feeling I get when I try to use LLMs for coding today. Every once in a blue moon it will shock me at how great the result is, I get the "whoa! it is finally here" sensation, but then the next day it is back to square one and I may as well hire a toddler to do the job instead.
I often wonder if it is on purpose; like a slot machine — the thrill of the occasional win keeps you coming back to try again.
