From my understanding, you are pretty safe as long as you don’t provoke them (walking through the middle of them might be considered provoking) or near their calves. This article from the UK states “Where recorded, 91% of HSE reported fatalities on the public were caused by cows with calves”. Basically, mothers with a child are going to be very protective.
Cows are a domesticated creature, so they are generally docile, but I would exercise caution because if need be they will use their mass and strength against you. I’ve heard of stories of farmers running from cows and narrowly escaping under a fence. Most of these did involve a farmer trying to separate a calve from it’s mother. I’ve also heard stories of cows jumping fences.
And as far as memes go:

Semi-cold? That’s extra, you’ll be lucky to afford it. The affordable water been sitting out on the pavement for a few weeks.
- Comment on Is it more energy efficient to charge a phone/tablet using a desktop/laptop while your computer is being used vs using the charger? 5 months ago:
This would only affect the 12V rail though no? It’s not like they are beefing up the 5V rail that supplies your USB ports in excessive amounts. Picking a random PSU from pcpartpicker, the CORSAIR RM650e vs RM1200e (650W vs 1200W) both have a +5V@20A rail. There would be no need to have a larger 5V rail to support gaming cards.
Also correct me if I am wrong, most PSU’s are more efficient at 20-50% utilization, not 100%. I’m basing this off the higher ratings for 80 Plus.

Your computer doesn’t “waste” electricity, power usage is on-demand. A PSU generally has 3 “rails”; a 12V (this powers most of the devices), a 5V (for peripherals/USB) and 3.3V (iirc memory modules use this). Modern PSUs are called Switched-mode power supplies that use a Switching voltage regulator which is more efficient than traditional linear regulators.
The efficiency of the PSU/transformer would be what determines if one or the other is more wasteful. Most PSUs (I would argue any PSU of quality) will have a 80 Plus rating that defines how efficiently it can convert power. I am not familiar enough with modern wall chargers to know what their testing at… I could see the low-end wall chargers using more wasteful designs, but a high quality rapid wall charger is probably close to if not on par with a PC PSU. Hopefully someone with more knowledge of these can weigh in on this.

A blockchain is just an verifiable chain of transactions using cryptography and some agreed upon protocol. Each “block” in the chain is a block of data that follows a format specified by the protocol. The protocol also decides who can push blocks and how to verify a block is valid. The advantages it has comes from the fact the protocol can describe a method of giving authority across a pool of untrusted third parties, while still making sure none of them can cheat. Currently the most popular forms are Proof of Work (PoW) and Proof of Stake (PoS).
Bitcoin for example is just an outgoing transaction to a specific crypto key (which is similar to a checking account) as a reward for “mining” the block, followed by a list of transactions going from a specific account to another account. These are verified by needing a special chunk of data that turns the overall hash of the entire block to a binary chunk containing a number of 0 bits in front, which makes it hard to compute and a race to get the right input data. This way of establishing an authority is called Proof of Work, and whoever is first and gets their block across the network faster wins. Other cryptocurrencies like Ethereum use Proof of Stake where you “stake” currency you’ve already acquired as a promise that you won’t cheat, and if someone can prove you cheated your stake is lost.
The problem it solves is not needing a trusted third party to handle this process, such as a government agency or an organization. Everyone can verify the integrity of a blockchain by using the protocol and going over each block, making sure the data follows the rules. This blockchain is distributed so everyone can make sure they are on the same chain, else it’s considered a “forked” chain and will migrate back to the point of consensus. This can be useful for situations where the incentive to cheat the system for monetary or political gain outweigh the cost of running a distributed ledger. It can also be useful when you don’t want anyone selectively removing past data as the chain of verifiability will be broken. The only issue with this is you need some way to reach a consensus of who gets to make each block in the chain, as someone need to be the authority for that instant in time. This is where the requirement of Proof of Work (PoS) or Proof of Stake (PoS) come in. Without these or another system that distributes the authority to create blocks, you lose the power of the blockchain.
Examples I’ve heard of are tracking shipments or parts (similar to how the FAA already mandates part traceability) and medical records. This way lots of organizations can publish records relating to these to a central system that isn’t under any single entities control, and can’t change their records to suit their needs.
These systems are not fool proof though, PoW has the ability to be abused using a 51% attack and PoS requires some form of punishment for trying to cheat the system (in cryptocurrency you “stake” currency and lose it if you try to cheat the system). Both of these run into issues when there is no incentive to invest resources into the system, a lack of distribution across independent parties, or one party has sufficient power to gain a majority control of the network.
Overall you are right to be skeptical of cryptocurrency, it’s been a long time since I participated due to the waves of scam coins and general focus on illegal activities such as gambling. The lack of central authorities also perpetuates the problem of cryptoscams, as anyone can start one and there are limited controls over stopping such scams. This is not dissimilar to previous investment scams though, it’s just the modern iteration of such scams. The real question is does it solve a real problem, as Bitcoin did in the sense it helps facilitate transactions outside of government controls. You might not agree with that but it does give it an intrinsic value to a large number of people looking to move currency without as much paperwork. Now if it makes it worth $68.5k USD (at current prices) is a different story, different people have different use cases and I only highlighted one of those.

How was the process before
I could find this on the process from theconversation.com:
For decades, UAW leaders were chosen through an indirect process common to many unions. Delegates to the UAW convention chose top officers, and regional conventions picked regional directors.
Has UAW been a sleeping giant this whole time on account of its leadership selection process?
I’m not sure how this affects overall union operations, but it appears there was a lot of corruption involved in UAW leadership that lead to this new voting process. Wikipedia has a summary on these events:
A corruption probe by the Justice Department against UAW and 3 Fiat Chrysler executives was conducted during 2020 regarding several charges such as racketeering, embezzlement, and tax evasion. It resulted in convictions of 12 union officials and 3 Fiat Chrysler executives, including two former Union Presidents, UAW paying back over $15 million in improper chargebacks to worker training centers, payment of $1.5 million to the IRS to settle tax issues, commitment to independent oversight for six years, and a referendum that reformed the election mode for leadership. The “One Member One Vote” referendum vote in 2022 determined that UAW members could directly elect the members of the UAW International Executive Board (IEB), the highest ruling body of the UAW.
Are stand up strikes common? Do they win concessions?
I can not answer to the commonality or how successful these “stand up” strikes are. Overall, striking in any capacity is a tool at the union’s disposal when contract negotiations reach a disagreement. How effective this will be is yet to be seen.
