second--shift··on The biggest churches in the world: Anglo-Norman eleventh-century cathedrals
As an aside, the name of the city is Córdoba - not "Cordóba" which would be the default pronunciation with no accent.

That said, Spanish / Moorish middle-age architecture is among the best and most beautiful in my opinion. Seeing how the later Christians borrowed so heavily from Islamic architecture and tradition shows that good ideas survive the test of time.

second--shift··on Experiments on a $50 DIY air purifier (2020)
Great study & article. Perhaps incense is not the most scientific test, but it's effective enough for this setup.

Does anyone know if there is raspberry pi add-on or device that acts as an "air quality" sensor, or similar? It would be interesting to monitor this a bit more scientifically in real-time in a variety of environments.

Lastly, I think I've seen this here before, or on reddit. I was inspired to do something similar myself - I use a 19" box fan and a purple 3M MERV furnace filter, 20" square. Except the rounded corners they are almost exactly the same size. Some white duct tape around the edges to seal/hold in place. Total cost is about $40 usd for the fan & filter. I would anticipate a similar performance to the leaky MERV's, as mine is filtering more air as a ratio to total air flowed by the fan.

who buys these instead of Lenovos for running Linux on?

Lenovo T14's are going for 65% of the asking price of one of these, if you don't care about intel vs amd.

second--shift··on FCC Temporary Waiver Permits Higher Symbol Rate Data for Hurricane Ida Traffic
I've heard this several times about ham radio, and to me as an outsider the idea of shared access to the medium is a bit off-putting to me.

Is it possible to have two-way links "in the clear" but otherwise encoded or ciphered? Is there a regulation that says all transmissions must be in English, for example, or can I transmit in Esperanto/Navajo/hex?

second--shift··on European Union recommends halting non-essential travel from the U.S.
> This is without prejudice to the possibility for member states to lift the temporary restriction on non-essential travel to the EU for fully vaccinated travellers.

I already have a trip planned to a Shengen country, planned months in advance. Everything is already paid for. I am also vaccinated fully (with certificate). Am I going to be allowed on my vacation next week?

second--shift··on Ask HN: Companies of one, what is your tech stack?
| If CentOS Stream is going to be just a FOSS upstream for RHEL, will you still pick Fedora Server over it?

Yes, but only because Fedora Server is (also/even more) a FOSS upstream for RHEL. Doing something that isn't Fedora (Workstation/Server) is "one more thing", however small, and I'd rather spend the brain tokens elsewhere. If it 10x'ed my app I'd do it, but I can't imagine it would.

Thanks for the links, I wasn't so mad at CentOS Stream the product itself per se, I think it's a valid product / change to the old model. My biggest issue is the changing of the promises - the supported life of the product changed in-production. That's a big no-no to me.

Fedora (upstream) requires you to keep up, but at least it doesn't make promises that it won't keep.

second--shift··on Ask HN: Companies of one, what is your tech stack?
Several.

I already use Fedora Workstation and am familiar with the environment, install, and setup process. CoreOS' "happy path" seems to be cloud (or at least hosted in a hypervisor) -native, and that was not the target here. There seem to be external dependencies on installing it to bare metal I didn't want to mess with[1]. I installed Fedora Server from .iso almost exactly the same way I've installed Fedora (workstation) many times.

My "day job" uses rhel, and with the recent CentOS end-of-life debacle I'd like to stay both FOSS and .rpm-compatible with rhel. I don't know for sure, but I think CoreOS is a different "vertical" than the fedora/rhel/centOS family.

I'm generally wary and suspicious of "automatic" updates, preferring to control when/how updates are applied to my machines. $ sudo dnf system-upgrade is a well-known quantity to me.

I have a complicated LVM setup, and significant time/effort already invested into LVM. As of F34 LVM/ext4 is still first-class.

CoreOS seems to be targeting cloud/kubernetes as implementation characteristics, and my "one man shop" gig is the anti-that. I'm pretty old school - only just started learning Docker about a year ago. I've recently bought into containers as packaging/deployment aids, and using docker-compose to keep deployment in version control. I guess all of this is to say I'm trying to "keep it simple / stupid" and re-use what I already know. Unless CoreOS can give me order-of-magnitude performance gains, I don't know the value prop beats the cost to pick it up.

second--shift··on Ask HN: Companies of one, what is your tech stack?
Golang backend, some light vanilla Javascript frontend. postgres db. running on podman (docker-compose), fedora server.

I have some background in C programming, so Go was easy to pick up. the standard libs are great for building server-side webapps with a sql backend. templates lib and some glue javascript make front-end pages a breeze.

I'm a linux guy thru-and-thru, so running fedora server on the latest kernel. latest podman from RedHat and docker-compose to orchestrate.

I'm one guy so I don't do any HA or cloud or any other funny business. My one server is racked nearby and I've had good history with the colo.

second--shift··on Ask HN: Anyone prefer a terminal based coding setup?
emacs -nw is where i live.

just stick with emacs defaults, or if you already know vim use doom or evil mode.

emacs' modes give you syntax highlighting, formatting, code completion, a repl, and more. I do a lot of python work (not too much C), and still prefer emacs+python over vscode, idle, others.

second--shift··on Amazon third-party sellers reportedly hound customers who leave bad reviews
Aha - that's what this is. I keep wondering why many sub-20$ items on eBay keep getting cancelled on me. The equivalent item on Amazon is usually 20-25$ (but doesn't quality for free tier shipping on its own) so I shop eBay for same - half the time or more recently it's either a) a drop-ship from Amazon even in its box/packaging, or b) cancelled as 'buyer requested cancel'. I knew it was a scam but I didn't know what for.

Good thing I ship to a PO box and use a generic C/O name.

second--shift··on Climate crisis: Scientists spot warning signs of Gulf Stream collapse
For people in eastern USA or Western/Northern Europe, the jet stream collapse is gonna be "the big one". Up until now, climate change has been a gradual-ish slow-boil process.

If the jet stream collapses, your long-term climate changes overnight. Eastern USA cities underwater, Western Europe 5C colder.

second--shift··on Entire German bond yield curve back in sub-zero territory
The fundamental problem with your hypothesis is the time-value of money: overnight deposits can be moved around, well, overnight, but a 30yr bond (for the bondholder, ignoring secondary markets) locks up capital for decades. A bondholder can't take advantage of future preferential interest rates when their capital is already locked up in low-yielding bonds.

This is why bond price and bond yields have an inverse relationship.

second--shift··on South Korea: The only middle power of its kind
pretty poor, as a percentage of land mass.

not too bad, as a percentage of population.

Most of Indiana by land is (very) rural, and in probably half of counties the fastest internet available will be sub 10Mbps.

In the major metro areas, Verizon/Frontier, Comcast, and AT&T "compete" and provide 1Gbps, with Frontier at least offering FTTH. I pay $60/month for 400/400 fiber.

second--shift··on Ask HN: Best Place to Live in 2050?
This would have been my vote.

In 2050, there may be a Northern Hemisphere Jet Stream collapse. Everyone here is posting about how things are gonna warm up - Western Europe is going to cool down probably in a 1C or 2C warming scenario. W. Europe is further north than people think.

The Med is a great heat sink / battery and regulates the local climate. Imagine Nice in the spring, or Barcelona.

second--shift··on Ask HN: What's the weirdest/best thing you've done with Emacs?
I've taught a stripped down emacs/org-mode to my partner to manage a hand-crafted meatspace recipe book. Their only "computing" otherwise is done on a smartphone (no laptop or desktop usage at all).

They use org-mode to give structure to the document and then export to HTML with and embedded .css I made with appropriate styles added. This .html page gets printed from Chrome and cut up / added to the recipe book.

My partner couldn't be less interested in tech/computing, but is using emacs as a tool to create a handmade art project. I dunno about weirdest, but this is my example of how emacs can be anything to all peoples.

second--shift··on Ask HN: Where would you incorporate in 2021?

second--shift··on Ask HN: Favorite purchases of last two years?
the GMC Safari is a real body-on-frame truck, with a van body. I have seen Astrovans with half a million miles on them, going strong.

I agree that the Grand Caravan is a bit flimsier, but mine has been in the family since it was new and well-maintained. Still strong 12 years later

second--shift··on Ask HN: Favorite purchases of last two years?
I always say "the best compact pickup truck these days is a Grand Caravan"

> So do I have to ride horses to get my privacy back now?

You say this in jest, but depending on your locale and transport needs, you could consider a motorcycle or bicycle. The interface is a bit like riding a horse, just more 21st century (obviously).

Modern bikes come with ABS and fuel injection, and tires these days are great. Motorcycles don't come with any of the annoying road-car nanny-state stuff. Riding a bike is cool too.

If so, many thanks to you for your labor of love. I have been jailbreaking iPhones since 2012 with your help. I'm sorry that the corporate structure railroaded you.

second--shift··on Experian’s credit freeze security is still a joke
Hello, a friendly correction if I may. In English 'grind' and 'halt' can function as both nouns and verbs - the common colloquialism is 'grind to a halt' where grind is the verb and halt is the end state.

In response to your comment, I think that the Norwegian system is inferior in the respect of the end-consumer having the final responsibility. I think that if the bank had final responsibility for any credit fraud, the fast-tracked system would hiccup perhaps, but not grind to a halt. Fintech is evolving rapidly and a new innovation could satisfy both fast banking and keep incentives correctly aligned between banks <-> consumers.

second--shift··on Fedora Linux 34 is officially here
no snap! This is really my biggest issue.

We use RHEL/rpm-based linuxes at work, and it helps to have a package building environment at home the same as it is at work. Everything else is or can be configured to be the same, for the most part.
