>Only if you use the time saved to write more data than you would have with a slower drive

Well, NVMe SSDs do get quite hot due to much higher data transfer speeds, and higher temperatures lead to faster flash memory degradation, although I have no idea how important it is in practice (probably on the order of an SSD dying in 10 years instead of 20)


Consumer NVMe SSDs only get to those higher temperatures if you're writing a lot more data than a SATA SSD or hard drive could handle. And such higher temperatures might at a stretch have a meaningful impact on the data retention time for data currently stored in the SSD, but won't meaningfully shorten the program/erase cycle count.


Flash has (much) worse data retention at higher temperatures, but endurance actually increases with temperature. So the optimal way to handle flash memory is mildly hot when written to (to increase endurance), but stored cold (to increase retention).


FWIW I've been pretty happy with Senseair S8 0053 for my DIY stations. They're relatively expensive though.

Not affiliated in any way.


Yes the Senseair S8 is very good. Only problem is that the automatic baseline calibration sometimes needs 7-10 days to kick in. But you can also do a manual calibration.


> co2 and pm should both go down with windows open.

Very much depends on where you live. I have a few DIY air quality stations with data being piped to Grafana. I just looked at the latest data, the average outside PM level for the past 5 months has been around 100 µg/m³, while inside it's around 10 µg/m³.

This spring happens to be pretty windy and this skews the outside levels down, otherwise the ratio would be much worse.


You'll be waiting on that gas station for hours for the payment to go through.


Yes which now stands at $37 on average which is probably more than you what you bought at the gas station. Ethereum fees are very high too. There are other currencies that are better with this. But currently my credit card does this at a fee of ~3% instantly.


I'm curious where the $37 number comes from? I just did a quick search and came up with $13.64 for a "high priority" transaction (higher than normal fee to get included in a block sooner)[0]. It's still high, but not $37 high.

I got that from here: https://ycharts.com/indicators/bitcoin_average_transaction_f...

Of course the "average" might be more bytes than buying a pack of gum but the argument still holds that the transaction costs are prohibitive for general commerce.


Part of the problem is that the seller pays that, and not you


The average transaction cost is baked into sticker prices, so at the end of the day, it's the buyer who pays the transaction costs. It's like saying 'the merchant pays rent' - yes, in a way, but really no. The customers pay the rent for the merchant via mark-ups.

However, there are a number of benefits; for one, average ticket size is about 20% higher for credit transactions vs cash (if I recall correctly) and merchants do not have to hold onto and manage piles of cash. This is a material cost savings.

Further, of that 3%, about 0.1% goes to Visa, the rest goes to the issuing bank and covers the cost of rewards programs and loan origination. Generally speaking between 1 and 2% of that will be rebated to the buyer.

For the remaining 0.9-1.9%, customers get benefits like insurance and the ability to issue chargebacks.

In Europe, debit interchange is capped at 0.2% and credit at 0.3%, and they just don't have insurance or rewards.

As it stands today if you wanted to transact in crypto, not only will you pay the $30 fee, you'll also be paying the mark-up for credit acceptance.


I know how credit cards work. I'm saying that Ethereum fees could be priced in the same way and you'd also never notice them because they'd get aggregated over every purchase. I realize this isn't a realistic scenario, but I think it's ignoring a monopoly type situation to accept that credit cards can price their costs in and other types of transactions cannot.


> As it stands today if you wanted to transact in crypto, not only will you pay the $30 fee,

Only bitcoin and ethereum have fees in this range. Other cryptocurrencies do not.

Indeed, and thank you for sharing the link, I've been looking at crypto transaction fees one-off so it's nice to have them overlaid.


its "priced in"


Not really. Your wait depends on the attached transaction fee and current network conditions. If you cheap out, then yes you have to wait, but it's also entirely avoidable.


The original Bitcoin continued as Bitcoin Cash. Very low transaction fees and always included in the next block. BCH ftw


Why would you need to wait for the transaction to confirm? That’s not how bitcoin payments work.


What else did you expect on a ~~hacker's~~ founder's site? Make a billion and retire before hitting 20, that's the goal.


I'm not sure when "hacker" became a synonym for "ruthless capitalist" but it's sad to see, honestly.


The ability to understand and praise (although not share) someone else's goals in life!


Where are the exploits for TempleOS? Come to think of it, where are the users, and where do most security researchers direct their attention to?


If SerenityOS can be a target for exploits then surely OpenBSD can.

https://devcraft.io/2021/02/11/serenityos-writing-a-full-cha...


Open bsd is targeted and does get CVEs though... the question is about the amount of attention compared to other platforms


Well, popping a toy OS for a CTF challenge does make it a target, yes.


I'm doing this also, and for the same reason.

>It's not uncommon that zooming will make the text smaller

At least in Firefox you can enforce the minimum font size through settings without using any third-party plugins or custom themes (look in about:preferences → "minimum font size"). I have it set to something like 16 or 18.

This doesn't fix the actual problem, but I gave up on trying to change the world a long time ago.


The problem with minimum font size is that sometimes you want the text to be smaller, especially in cases where it's used as UX labels or the like. I used to set it fairy high in Opera (long time ago, Opera Presto) and even back then it would break stuff.

I have a few custom userstyles to deal with the worst of it; topnavs that grow to 20% of the page height and stuff like that.


>Btrfs is probably never the right decision

And you're posting anti-btrfs FUD.

Even if it's the only deployment in the world, it's more than "never". They provide strong technical reasons for using it.


What? They ship prebuilt zfs modules along with the kernel.

  # dpkg -L "linux-modules-$(uname -r)" | grep zfs.ko
  /lib/modules/5.4.0-70-generic/kernel/zfs/zfs.ko
