Can you say more on how you support fair queueing with partitioned queues? Very top of mind for me right now!
I'd be very curious to see you add the Optimized Reads instance types, e.g. r8gd or m8gd, to your benchmark. They add a local NVMe-based SSD block storage that serves as a cache in front of the network-based disks among other use cases. They have been a huge win for us for a read-heavy workload where the dataset is significantly larger than memory.
Edit: Apologies, on a closer read, I realize you were not testing RDS but managing Postgres on EC2 directly.
I highly recommend a visit. It’s only a beautiful ferry ride and nice walk along the waterfront away from San Francisco. A refreshingly retro and analog experience.
Thank you! We generally try to stay in line with the supported versions of the technologies we use: Postgres, NodeJS, Redis, etc.
For Postgres in particular, part of the motivation for doing this upgrade when we did was (besides the very meaningful performance improvements) is that Postgres 12 will no longer be supported by Aurora after February 25, 2025.[0]
Officially, Medplum v3 (our current newest version) requires Postgres 12+. We're just about to release v4 which will support 13-17 based on the support dates published by Postgres[1]. We're still finalizing more formal documentation on our versioning strategy going forward.

Hey HN,I put together this blog post[0] and this repository[1] with supporting resources to immortalize the decision tree and step-by-step run book I used that led to us successfully upgrading the AWS RDS Aurora Postgres database of Medplum's hosted service from v12 to v16 without downtime. There are many write-ups out there on the topic, but just about all of them were frustratingly light on...
Agreed. I frequently go running by (all?) the filming locations they used. With the exception of the Hippie Hill location in GGP, I rarely, if ever, see homeless at any of the others.
As an aside, a few weeks ago I ran by a film crew with a lot of privacy fences set up at the location by the Warming Hut with bay and GGB in the background. Now I know what they were filming!
Congrats, Frigade! I'm on the team at Vanta that is revamping our user onboarding flows and really wish y'all had launched a couple months ago! Building out the platform to support these experiences internally is no small feat and can blow up in scope quickly. Kudos!
Eric was kind enough to take the time to send us candid and actionable feedback as he went through Vanta's onboarding which definitely helped us smooth out a couple wrinkles. Thanks so much for that.
Recent father of twins here. To reiterate points 3-5: if it is within your means, I cannot highly recommend a night doula/nanny enough. We have a night doula who comes five nights a week (work nights, Sunday - Thursday) for the first three months (currently in week 7). After fending for ourselves every Friday and Saturday, I can't imagine how drained I would constantly be without one.
I love pairing bitters with my sodastream! A few of my favorite recipes are: 1) Grapefruit & Cherry, 2) Cardamom, and 3) Orange & Cranberry. Clearly it's all to taste, but a 3-4 dashes of each bitter is a good starting point for a ~16oz glass of seltzer.
Fee Brothers sells a 12 piece variety pack which is a great way to experiment. After that you have quite a rabbit hole of bitters brands and flavors to explore!
For what it's worth, the second paragraph (about refusing to tip for jobs they are capable of performing) in the comment you replied to is a direct quote of Dwight Schrute's character from the US version of the the TV show The Office.

I was also very surprised by this. I'm having a hard time accepting that I'd have to manually concat my columns to create sort keys and keep track of the corresponding queries for them, e.g. "BEGINS WITH..."? Granted, I only watched the video so maybe I'm missing something and that was just to simplify the presentation.
Funny, I've been unable to get credit for any of my stays Marriott hotels in the last year. I rarely stay in Marriott/Starwood, so I assumed that my loyalty account had just expired or otherwise gotten in to a bad state even though I could still log in to the account online. I don't stay in hotels enough to get to higher rewards tiers so I just wrote it off. This likely explains all my failed attempts to accrue nights...
Big congrats to Tracy, Ralph, and the whole team!
Lots of YC companies | Software engineers of all kinds | Many places, though mostly in the US | Mostly on-site, but some remote | Full-time and intern
Earlier this year, a team of us at Y Combinator started a "common app", so that people could apply to work all Y Combinator companies at once. It seemed silly to us that even though so many companies are struggling to hire people, it still requires O(n) effort to apply to n companies.
So, we built https://workatastartup.com. It's a simple way to apply to all YC companies at the same time. Right now it's only for software engineers & data scientists for now (we hope to open it more broadly later). If a company is interested, you'll get an email from them. There is also a directory where you can browse the jobs of some of the companies that are actively hiring through the site and apply directly (not all companies have finished their director profile yet).
It seems to be working pretty well so far - many of the people who posted a profile have gotten more than a dozen company founders reaching out to them, and people have gotten jobs through it. You're most likely to have good results if you're looking for a full-time role in the US since that's where most YC companies are based.
We recently hosted an in-person career fair where the founders of ~40 YC companies from a variety of fields and of various sizes gave short presentations and then mingled with attendees. [0, 1]
We'd love if you filled out a profile and let us know what you think ([email protected]) : https://www.workatastartup.com

Thanks for the link! I just played around with the React and Vue.js implementations. With the Vue.js implementation, there is a perceptible lag (maybe ~300ms) between pressing Enter and the new item appearing in the list. With the React version, the same action is essentially instantaneous. Curious if anyone else is experiencing the same and/or knows what might be the cause.
After YC launched workatastartup.com earlier this year, we decided to relaunch an in-person expo and career fair of sorts to go along with it.[0] The expo consists of keynotes by Sam Altman and Justin Kan on the topic of working at a startup followed by presentations by 40 YC companies of various sizes and industries. We're live-streaming for anyone that's curious to follow along.

I'm not crikli, but we have similar tastes! Talisker is my go to dram.
Try Bruichladdich Islay Barley. It's heavy on the saltwater characteristic that Talisker and other Islays have but is overall a bit lighter in both color and taste. I don't recall which vintage I had, which supposedly makes a notable difference for this whisky.
Kilchoman is another Islay that I enjoy a lot.
If you want to delve further into the world of peat, checkout Ardbeg and Laphroaig 10. Laphroaig has other nice varieties like Quartercask and PX that aren't as peat-centric. Ardbeg also has a wide variety of offerings to explore.
Of course I would recommend trying before going in for a bottle on all of these since everyone has their own tastes!
Do you have any more information on this? They wanted 50% across the board or only from Moviepass patron concession purchases? I'm guessing it's the former, but if the latter, I'm curious how they identify such purchases.
As a counterpoint, I live SF and do not have room to spare in my closets or anywhere else in my apartment for a scooter. Urban living...
Everyone I know who has ridden a dockless rentable electric scooter has absolutely loved them. I've used them to commute to/from work (what would normally be a 20 minute walk turns into <10 minutes if I'm in a rush), quickly return home from ~3 miles away after running into Golden Gate Park (too sweaty for a Lyft), and running errands to destinations a bit out of walking distance during rush hour when public transit/Lyft would be painfully slow. The added benefit is that the scootering was more fun and less or comparably expensive to the alternatives.
Scooters have advantages over bikes as well for this type of usage. It is far easier to switch to pedestrian mode (i.e. walking next to the scooter) when you need to navigate a crowded cross walk or slow down suddenly and get up on the sidewalk when an aggressive taxi/Lyft/bus stops short in front of you or turns across you. Your center of gravity is lower than on a bike lessening the impact from falls in some cases.
The parking debate seems pretty bimodal and has been debated seemingly endlessly already...
The safety concerns complaint is interesting. Lots of bikers already ride without helmets but no one seems to care/complain about them too much. Lots of complaints about safety riding on the sidewalks, but I haven't seen much hard evidence that collisions are actually happening en masse.
A 10-15 mph cap in SF seems totaly fine for what is meant to be a casual, relatively short distance means of travel.
How are you concluding that the economics are mediocre?
What evidence do you have that people tend to treat them as trash? While I'm not sure how often Jump services/replaces their fleet, the few I've used and the many I've seen around SF have all worked great/looked to be in good condition over the past few months. Also, I've definitely seen vans redistributing Jump bikes around town. I fully expect Bird/Spin/Lime does/will do the same with the scooters.
Back in 2011, Solomon was nice enough to get lunch with me along with a few other DotClouders to talk me through some scaling issues my startup was stressing over. They were all super knowledgeable and helpful. We were able to get a handle on things thanks to their advice. Thanks so much and best of luck!
AngelList definitely has a great recruiting platform! One of the main differences right now is that Work at a Startup is a great way to get exposure to startups working on a vast array of problems in different industries. Right now we're working on making it more of a two-way marketplace where job-seekers will be able to browse all the YC companies that are currently hiring to find the ones who's goal/product really resonates with them.
Stepping back a bit, hiring is the most ubiquitous problem our portfolio companies report to us in the years after going through YC. Given that, building a hiring platform for our companies that YC doesn't need to directly monetize can add a lot of value and accelerate their progress post-batch.

> Rent Control surely just prevents local families from being muscled out by the tech employees?
Correct. And in the process of doing so, further contributes to the lack of inventory of market-rate rental units available to the influx of newcomers/tech employees.
As mentioned elsewhere in the comments here, this causes huge disparities for rents of similar units within a given building as landlords attempt to compensate for all the market-rate rent being missed from longtime tenants. E.g. I've known folks paying $4,000 while their neighbors pay $400. While I don't have numbers or a study to point to, my experience over the years with the SF housing market suggests the impact of this effect is nontrivial.
