I think the problem is the loss of the middle class. The ones on top getting a lot of the resources while the rest have to fight for whatever is left. It doesn't matter how hard or how smart you work.

I think that's a neat idea. I often use Google Sheets as a database for my projects. I read 'setup' data and 'log' data. Works well. Most often just append a row at the end for writing. But I can see why a CSV can be a decent idea too especially if it can be edited with a spreadsheet app. So I would put this on a server (a file share) and edit it as needed with Excel/Numbers/Google Sheets etc... and click save. My apps can read it and if writing appends a line then hurray! cool idea.
LikeBeans commented on Is an Intel N100 or N150 a better value than a Raspberry Pi?   jeffgeerling.com/blog/202... · Posted by u/transpute

I think both are great. It depends on what you need and the requirements you want to hit. I use an RPi for as a Pi-Hole for example. It works great. Low power and just that one task. Performs nicely. And cheap. However for my firewall (PfSense) I use a mini PC because I want the throughput especially when I VPN into it. Also works great for that task. So I think of it in terms of 'task' and it's footprint (ie storage/mem) and throughput.

Bonds and stocks tend to have an inverse correlation. And, yep, bonds are up while stocks and real estate are down.

That’s why financial advisors tell you to keep a mix of stocks and bonds, trending towards a greater percentage of bonds depending on your risk tolerance and as you get older. (Because bonds have lower returns than stocks, historically, but are also less volatile.)

Often yes but sometimes they both go down. However bonds don't decline as fast. The actual strategy I follow is stock/bond/short-term. The short term is like a buffer currently invested in short term treasury fund. Think of it like a game. If stocks are low then sell bonds and when that is also low then use the short term investment to live on to wait out the market recovery. Also if you are retired like me you would tighten expenses when drawing from the short term during a downturn.

So honest question: A bunch of people who currently own stock are deciding they'd rather have cash instead -- that much is obvious.

But what exactly are they doing with the cash?

Don't want to hold onto it, everyone says devaluation and inflation is coming.

Bitcoin and gold are kinda flat. I expected them to shoot up as uncertainty hedges. What gives?

Lookup VUSXX. It is a vanguard short term treasury fund. That's where I put my cash. It is currently paying 4.24% that is state tax free (I live in Oregon).

Unfortunately it is hard to predict if that rate will stay high enough. Previously I had 'cash' in iBonds which for a while paid 8-9% early in the pandemic when inflation was high. If none of the above pays well enough I look into treasuries, or CDs.

> It does if you consider that everyone can act as a relay.

Let's think this through. Imagine civil war breaks out in Australia, and communications infrastructure is destroyed or shut off. I'm in Sydney and want to transmit a message to a friend in Perth.

How exactly is "everyone acts as a relay" going to work? In particular, how is it going to scale when everyone in the country is trying to do the same things?

> This is also how apple airtags can be find anywhere there's an iphone users nearby.

This is incorrect. Airtags (and the Google version) communicate with nearby Internet-connected devices, via Bluetooth and NFC I think. Those nearby Internet-connected devices send the airtag's location to a server.

Nothing about this would work without the Internet.

Yeah, I think current tech assumes a server relay. However imo, and if I were to imagine a solution, in this case I think a message would need a ttl, say 24 hours. In a local mesh/hive everyone would store a copy of the undelivered messages. When people move between hives they would sync these undelivered messages where ttl didn't expire. With perhaps a storage limit of say 1k undelivered messages. Undelivered means a destination user that didn't show in a hive. Wdyt?

In simple terms, if I understand quantum computing, and please correct me if I'm wrong, the big benefit is parallel computing at a massive scale whereas classical computing is serial in nature. If yes likely both method are useful. But a very useful use case for quantum computing is AI training to create the models. Currently consumes a lot of GPUs but QC has nice chance to impact such a use case. Did I get it right?

Aren’t trains the perfect use case for a direct connection to the electric grid?
LikeBeans · 9 months ago
I can imagine running electric wires along tha tracks is a big challenge. However I think using the container BESS mentioned in the video above receiving trickle charge from the grid would leave opportunities for local solar generation to augment the grid too. Think of it like a decentralized solution. Scales much more and provides resilience against outages.

I just watched a YouTube video of a battery powered train in the UK [1]. If longevity and number of cycles is much higher than lithium ion coupled with a safer profile then I think this would be an ideal application for sodium ion. Really cool.

Edit: I'm talking about for both onboard batteries (for the safety profile) and the BESS container mentioned in the video. Not to mention trains wouldn't have to compete with the lithium ion battery supply that is taken over by EV cars and trucks.
