Sodium Hydroxide, when exposed to Carbon Dioxide (already in the air), combines to become Sodium Carbinate.

NaOH + CO2 → Na2CO3 + H2O

Sodium Carbinate then reacts with water and more Carbon Dioxide to become Sodium Bicarbinate, which is baking soda.

Na2CO3 + CO2 + H2O → 2 NaHCO3

Not only does a Sodium Oxyde fuel cell produce electricity, it takes CO2 out of the atmosphere.

From a physics and chemistry point of view, it’s pretty cool. I’m curious how well it scales though.

Depends which part of myself I’m talking to. If it’s just a general conversation, it’s “we.” If it’s more of a direct conversation to a part of my mind, it’s “you.” If I’m talking about myself to a third-party, such as this response, it’s “I.”

“The government” is multiple agencies and departments. There is no single computer system, database, mainframe, or file store that the entire US goverment uses. There is no standard programming language used. There is no standard server configuration. Each agency is different. Each software project is different.

When someone says the government doesn’t use sql, they don’t know what they are talking about. It could be refering to the fact that many government systems are ancient mainframe applications that store everything in vsam. But it is patently false that the government doesn’t use sql. I’ve been on a number of government contracts over the years, spanning multiple agencies. MsSQL was used in all but one.

Furthermore, some people share SSNs, they are not unique. It’s a common misconception that they are, but anyone working on a government software learns this pretty quickly. The fact that it seems to be a big shock goes to show that he doesn’t know what he is doing and neither do the people reporting to him.

Not only is he failing to understand the technology, he is failing to understand the underlying data he is looking at.

My guess is that the label is wrong. My water bill has the same chart with about double the usage as yours, but same ranges. On mine, the label is “gal (in hundreds)”. I’m betting that some developer just didn’t put the full label on the screen.

Best audio book I’ve listened to… Dungeon Crawler Carl. Great story. Amazing audio book production.

I agree with what you’re saying. They got the phone from Carrier A with the expectation the phone plan went with it. Once the phone is paid off, they can take the phone to Carrier B. Since they phone is basically bought on an interest free loan, the interest is recouped by the plan, and the collateral for not paying is a loss of the phone plan and use of the phone. To leave the plan, payoff the phone.

That does require that, the moment the phone is paid off, it should be automatically unlocked. There shouldn’t have to be a request or additional waiting. And the customer should be notified that it’s unlocked along with an explanation that they can now use the phone with any other provider.

If that were the case, how did you know to post about it?

I run a development department, and nobody who reports to me comes to the office. We have been 100% remote since 2020… much to the chagrin of HR. Others in IT come in, but no developers. I see no reason to change it either. I question why I even come in most days.

Without looking it up, I don’t know how many people I’ve interviewed over the last 4 years, but there’s been a few. I’ve only had one person who indicated he wanted to be in an office. Every other person wants fully remote. The most common comment I’ve heard from people is saying they will settle for hybrid if full-remote isn’t available.

There’s some value to having people work together in-person, but I’d rather give my teams the flexibility to choose for themselves rather than force it.

Over a lifetime, 7% to 8% is a good return. If you are safely building a portfolio, and looking at year over year, then anything between 8% and 12% is pretty good. If you are closer to retirement or just more risk averse, then around 5% to 7%. Really, anything above inflation means you are making money.

Everyone is going to have different definitions of “good.” It all depends on your goals, risk aversion, and stage of life. Your best bet is to find a financial advisor who can tailor a plan to your needs.

A quarter has 13 weeks, so if you do 2 week sprints and align them to start with a quarter, there is 1 week per quarter that is not accounted for. That week can be used for stuff outside of daily activities. It can be used for training, offsites, working on a pet project, etc. Its a good way to build time in the schedule for this type of thing. These types of breaks have tremendous long term value.

AC as refrigerant, not coolant. Although that might be semantics.

AC is a type of heat pump. You are moving heat from inside to outside. The physics behind a heat pump, is fairly simple. There are three principles to work with.

1. Take a gas, compress it, and it gets super hot.
2. Take a compressed gas, let it rapidly expand, and it gets super cold
3. Different temperature gases move from hot to cold

Let’s focus on AC since most folks are used to that concept. In an AC, you have a closed loop of refrigerant. Outside, there is a compressor that compresses the gas, which makes it very hot. The gas is pushed through a radiator with a fan pulling air through it. Since hot moves to cold, the heat trapped in the gas moves to the outside air, and the gas is slightly cooled. (As long as the gas is hotter than outside).

Inside, there is an expansion valve that lets the gas rapdly expand, making it super cold. It is pumped through a radiator that has inside air blowing over it with a fan. Since hot moves to cold, the heat in the inside air moves to the cold gas, cooling the inside air. (As long as the gas is cooler than the inside temperature). It is then pumped outside to start the loop again.

So, inside gets cooler while the heat is moved outside. The physics also establishes the limits of the heat exchange. You will only grab heat from inside if the expansion makes the gas colder than the air inside. Typically it expands to around 0 degrees. Likewise, it will dump the heat outside if the gas is hotter than outside air. The compressor typically makes it 130 to 140 degrees (temps vary depending on many factors).

To use a heat pump for heating rather than cooling, reverse the process. Pick up the heat from outside and dump it inside. This will work as long as outside is warmer than the expanded gas (0 degrees or so). Although you can get some that go to around -20.

Then why would the company be against paying minimum wage?

More of a physical representation of a debt, but in essence, yes.

I buy a rock from you with $5, that $5 represents the debt I incurred by taking the rock. You have the $5 that you can use to barter for something else. At the end of the day, the government is backing my debt for the rock with a physical piece of paper. Except it isn’t physical anymore now that everything is digital. So, I suppose its more like the bits of data that represent the physical money that represents the debt for the rock is backed by the government. Although that money is actually physical at the bank that conducted the electronic transaction, and they borrowed that physical money from the fed. But even then, it is inflated since not every dollar a bank transacts with, is backed by something physical since the reserve ratio is not 100%. And that is when it starts becoming confusing.
