quartz··on Tell HN: Google search partial outage while rolling out new search?
Google.com renders for me but 0 results for all searches :-O.
quartz··on Estes Rockets Model Scale 1:100 Replica of SpaceX Falcon 9
I built and launched countless model rockets as a kid and a month ago took my son out with my dad to relive the experience and it was downright magical.

Beyond that I'm really happy to see this model simply because it's REALLY HARD to find toy or model SpaceX rockets.

Science stores and museums are still packed full of the same old space shuttle and rocket models and toys that were there in the 90s which is kind of ridiculous considering we have way cooler rockets now and the space shuttle has been retired for over a decade.

The official SpaceX store only sells t-shirts and hoodies.

quartz··on Bob Lee, former CTO of Square, has died after being stabbed in San Francisco
The second paragraph for both your links tries to compare the cities in terms of apples-to-apples by population:

NYC: "However, compared to other communities of similar population size, New York has a crime rate that is noticeably lower than the average. This means that for comparably sized cities all across America, New York is actually safer than most according to NeighborhoodScout's exclusive analysis of FBI crime data."

SF: "Importantly, when you compare San Francisco to other communities of similar population, then San Francisco crime rate (violent and property crimes combined) is quite a bit higher than average. Regardless of how San Francisco does relative to all communities in America of all sizes, when NeighborhoodScout compared it to communities of similar population size, its crime rate per thousand residents stands out as higher than most."

Edit: having lived in both (currently in NYC) I also want to point out the two cities are incredibly different in almost every way. It's really tough to compare data across the whole "city" between the two because of the differences in geography, population density & distribution, types of crime, history & expectations, and overall city governance.

quartz··on Playing video games can help to reduce stress and anxiety, and improve mood
I have a dentist who loves to use the little remote camera to show me everything about my teeth and let me tell you: it doesn't make it any better!

Totally agree on the "understand to remove fear" side of things though.

When I was learning stick shift I had a terrible time until, frustrated after I had stalled the car for the umpteenth time, my dad stopped the lesson on "what to do" and instead spent a few minutes explaining what was actually happening inside the clutch system.

Suddenly it all made sense and I understood what I was actuating and why the feedback was the way it was. I became proficient quickly after that.

quartz··on SVG Backgrounds
Very cool!

Small bug report: on Safari 16.3 (18614.4.6.1.6) when you hover over one of the circles to pick a new background, during the animation the circle's interior extends outside the circle's border.

quartz··on Pacific Pinball Museum
I'm so sad about modern pinball closing. It was such a gem.
quartz··on Silicon Valley Learns to Love Socialism for the Rich
I mean, that's literally what happened with the UK arm of SVB: https://www.cnbc.com/2023/03/13/hsbc-buys-silicon-valley-ban...
quartz··on Control Mario Kart 64 with your car over CAN bus (2016)
I love how clever this is!

If I wasn’t pretty sure that gunning the engine in park repeatedly is a bad idea (and would draw more than a few stares when done from a street-parking space in Manhattan) I’d give it a try.

Would very much like to see a video of someone using this.

quartz··on Twitter refused to pay AWS bill, so Amazon refused to pay for ads
I can't speak to AWS but in my experience with an expired credit card and a few dollars owed on an otherwise unused account Azure will permanently destroy your data and resources after about 5 months.
quartz··on Doom the Way It Was Meant to Be Played – v1.1 Multi-Monitor [video]
Funny, that's actually how Jay Cotton (co-creator of Kali) learned about Doom and what led him to start exploring the network side of gaming.

There's a decent interview with him that relays the story: https://episodiccontentmag.com/2016/08/26/kali1/

quartz··on Pre-seed, seed startups with employees in office have higher revenue growth
YC probably has some really interesting data on this for pre-seed companies since moving from a required relocation to fully remote.

For new founders the value of being in person around other founders in the epicenter of your industry can be pretty huge. It's the questions you don't know to ask that are often the most valuable-- the overheard conversations, unexpected connections, and coffee chats that often make the difference between survival and death in the early days.

IIRC early data during the pandemic indicated that while remote work didn't impact productivity for established employees it was harder for new hires to find personal traction within the company.

quartz··on How we learned about coffee delivery
Briggo kind of did this. They started with convention centers and airports. Costa bought them reasonably quickly.

It was the perfect middle ground: it didn’t claim to be top of the line but it beat most chain coffee for espresso drinks.

quartz··on How we learned about coffee delivery
Great article, I and many other founders I know have had a version of this idea (fast, high quality coffee, delivered) and no one I know has made it work.

Since you lived this journey I'm curious about your pricing: I always imagined that I'd be willing to pay a pretty huge premium for this kind of a service if it felt "luxury" enough. Kind of like how Uber started off at the high end with $18 minimums before it had to battle on the low end.

It looks like you were charging 10% over the nearest shop price, but if the experience was high quality enough could you have charged closer to $7-$10?

quartz··on Why Is Colorectal Cancer Rising Rapidly Among Young Adults?
My family has personally experienced this and it is terrifying to learn how little information and how few resources there are for young children with IBD.

Right out of the gate you hit the issue that there simply aren't many "very early onset IBD" (impacting children under 6 years old) specialists because historically there were so few cases. We've seen well regarded IBD specialists who reflexively try to order tests and procedures that their own hospital will then refuse to even perform because they can't be done safely on young children. The IBD specialists are in general simply unfamiliar with young children because of the historical rarity.

From the VEO IBD specialists we have worked with they all report that the numbers are exploding and no one has any real idea why.

On top of that most of the more modern and effective treatments for IBD and Crohns aren't approved for young children at all and even top tier insurance will fight tooth and nail against covering them because their use in children can be considered off-label.

quartz··on Is AM radio dead?
Oh sure, the list of FCC rules is seemingly endless... but it's still a pretty wide margin of media and speech permitted especially on the "talk radio" side of things.
quartz··on Is AM radio dead?
I seriously considered buying an AM radio station a few years ago. You can get a fully operational station and the land it's on for under $200k in pretty populated areas.

Something about just broadcasting whatever you want into a protected frequency band for anyone with an antenna to hear seems really cool.

quartz··on Automerge 2.0
Excited to see this!

I built a personal project with automerge 1 recently because I liked the philosophy of offline-first from the team and because the docs were frankly much more approachable than yjs but ended up switching to yjs half way through because of performance issues and also for the rich text support (via the delta doc type).

A little bummed about 2.0 not working with react native because of webassembly but excited to see the peritext work progress for rich text coming soon.

CRDT is one of those technologies I assumed was “done” a decade ago and I was surprised to learn how much of the major progress was only just recently made when I dug in.

Definitely expecting to see some cool new multiplayer startups built on this tech.

quartz··on An investigation into Apple’s new Relay network
Relatedly I recently learned that Apple also has a "protect mail activity" option that seems to use private relay under the hood for email content. You can use this feature without actually enabling private relay for your whole machine.

I discovered this because pihole blocks private relay by default and I was getting an error in the mail app that it wasn't able to protect my activity: https://apple.stackexchange.com/questions/429899/why-am-i-se...

Have to say I'm a big fan of apple trying to bring more of these features to average users. I had just finished prototyping my own mail server to do exactly what "hide my email" does when apple announced that feature and was very happy to be able to throw that code out in favor of something built into my mail client (although it was actually pretty fun to learn dovecot and postfix).

quartz··on Show HN: Interact with the terminal in plain English using GPT-3
This looks really cool. The number of times I've had to google things like "delete all files that were created before a certain date but not if they have certain characters or are a certain extension" is uncountable.

Kind of wish the command was just "genie" though. Suppose I could ask it how to change the name.

quartz··on PagerDuty to Lay Off 7% of Staff; Revenue Officer to Exit
While not difficult to build a basic version, at-scale incident alert & escalation systems are a mix of all the things that engineers hate building for (timezones, calendars, telephones, human-injected overrides, contact management, and 3rd party notification / acknowledgement tracking) all wrapped into a system that's being watched and scrutinized by everyone from compliance, legal and eng all the way to the CEO when they're at their most emotional during and after an incident.

IME for most companies it only takes a homegrown system failing once during a major outage for the budget to open up.

quartz··on Choosing a Postgres primary key
Given the advantages of sortable UUIDs and this post's conclusion that XID is the best option right now, is Supabase planning to add pg_idkit to their list of supported extensions?
quartz··on Apple offers $970 in trade-in value for $52,199 Mac Pro
I'm trying to figure out what "dropped 50x" even means... wouldn't that be like -$2.5 million?

quartz··on Binance's books are a black box, filings show, as it tries to rally confidence
Sounds like you've already got it right there: implemented well a decentralized blockchain is basically a 3rd party as a transactional service (which through programmability can act as a ledger or escrow).

The commenter up above is directly referencing where existing 3rd party / escrow services are pretty terrible today and they're certainly not easily accessible to the general public or your average piece of computer code.

A lot of the pre-boom blockchain contract excitement really was as simple as "turn the awful banking middlemen into code so we can get the advantages of them programmatically."

quartz··on John Carmack Leaves Meta
Nintendo seems to be the best at this. I pulled my Wii out of storage to play with my 4 year old earlier this month. Plugged it in and was off and running having a blast playing Wii Sports and Mario Kart.
quartz··on Tailwind is a leaky abstraction
> These issues don't mean Tailwind is bad. They're just some of the tradeoffs you inevitably encounter when using a tool.

A fair conclusion.

quartz··on Ask HN: Indoor air quality sensors and other IoT that's local-first and not DIY?
Nice. This seems like the perfect solution and fits OP's requirements!
quartz··on Why doesn’t the U.S. have at-home flu tests?
IIRC one of the only useful things Theranos did was to lobby to remove the laws preventing people from ordering their own bloodwork without involving a physician.

That said, the two big lab companies are starting to offer more self-ordered tests which is cool: Labcorp has ondemand (formerly pixel): https://www.ondemand.labcorp and Quest has QuestDirect: https://questdirect.questdiagnostics.com/

quartz··on Resolving the great undo-redo quandary
Oh cool-- are you saying Alfred will let me override the delete key in the case of highlighted text so it always executes a cut instead?
quartz··on Resolving the great undo-redo quandary
Semi-related: What I really wish all my editors and IDEs would have is some kind of "delete history" view into my deleted text (especially blocks of text).

I'll often delete something, then work for a while, then realize I need that thing back again so I have to VERY carefully undo everything after the delete until I get to a point in history before it, copy the deleted text, then re-do everything back to my original state while making sure not to accidentally execute any inputs which would burn down the redo stack.
