More posts about mysql from Uber - it is interesting to compare state of Mysql in Uber with 2016.

* Why Uber Engineering Switched from Postgres to MySQL (2016) https://news.ycombinator.com/item?id=26283348

* Upgrading Uber's MySQL Fleet https://news.ycombinator.com/item?id=41836748


The comments are pretty interesting. There was a discussion about how different they were trying to make the public image about their tech look compared to their actual usage - supposedly to entice more engineers to join.

I think its interesting to attach any company prominently to a database technology since theoretically there would be varied use cases across an org like uber which would likely want different technologies depending on those use cases. Of course they might just have 50 other articles like this for all the other tech they use.


Yup Netflix is similar. Your tech is not that hard and the good engineers can see through the BS.


Streaming video at Netflix's scale in the year 2010 was hard though?

I mean sure, it's a lot easier nowadays - but that's mostly down to cloud providers replacing half of the server-side challenge with a big bill and fiber making the last mile easier too.

You're massively underestimating the challenge of transferring these vast amounts of data without interrupting service for buffing etc that they had to solve back then


Pornhub solved it much earlier with PHP


tbf it’s easier if you only need to serve the first 5 minutes of a video


According to Pornhub's 2024 Insights blog post, (nope, not gonna provide an URL, use a search engine :))"

    "...making the average engagement time per visit 9 minutes and 40 seconds"
Reading about the variance and what demographic groups visited the site for shorter or longer amounts of time will keep you amused.


ah I know the blog post ;) I just thought it was ~5 minutes, but its ~10 minutes ;) still way easier to do that than netflix ;)


Another interesting one about their Storage Platform (which includes MySQL): https://www.uber.com/blog/odin-stateful-platform

> The [Odin] platform supports 23 technologies, ranging from traditional online databases such as MySQL® and Cassandra® to advanced data platform technologies, including HDFS™, Presto™, and Kafka®.


I’ve installed 4 similar skylight lamps to the basement. Bought them on Amazon for 700$ each (had to replace 1 because it had uneven light). They make basement light much closer to ourdoor light and made basement very cozy and comfortable. I had depth space in the ceiling, but width of the lamp didn’t fit between joists - so could not push lamp all the way at the ceiling level. End up building nice boxing around lamp. So it was medium complexity project with great result.


I really miss StackOverflow Careers because they had exactly this feature - I enter my career details once and SO Careers allow me to generate nice CV in PDF format. Personally I’ve found couple great jobs though SO Careers, it is sad that SO decided to shutdown Careers business.


I can suggest improvement - combining long running e2e tests with notebooks is even better match


> I predict they'll produce another small phone in a few years. It'll sell well due to pent up demand, and someone will be declared a genius for selling 100M's of extra phones that year.

I’d wish this too. I’m afraid that Apple over the next few year would become more risk averse then ever before. Also old Execs are leaving and retiring - so less people with hands on experience how to start new products VS keeping lights on.


Good luck. I’ve tried to replace battery in mine 12 mini last week - with no success. I had to leave my phone for 4 hours or several days (if they brake screen during battery replacement, they will wait for replacement phone to be shipped overnight). Also representative was convincing me to buy a new phone - saying that battery replacement won’t help much because new ios versions has features which high battery usages, while newer iphones has larger battery and hardware optimizations for these new features. I’m thinking about iPhone 16 now while keeping iPhone 12 mini as backup phone.



I've successfully have replaced batteries and displays in older iphones (mainly iphone 6). But with newer iphones opening the phone is more complex.

I've read online and heard from Apple Store representative that iPhone 12 (all models) has tendency to crack the screen when phone is opened for repair or battery replacement and in that case Apple Store would replace the hole phone (this is were multi day repair process). So I would rather pay $90 to Apple that guarantees that I'll get a phone replacement in case when screen is broken during battery replacement. Without the phone I sill would be able to answer the cell calls from Apple Watch and with ipad over WiFi.


Oh boy I hope that doesn’t happen to me. It took them a week to get iPhone 13 mini battery in.


I recently brought an SE2 in for a screen + battery swap, which basically means they'd just give me a new SE2 at a steep discount.

They didn't try to upsell me at all, but I ended up getting an SE3 anyway (I didn't realize there even was a newer SE).


This is nice of them. I think this is because screen replacement was required and them not having SE2 in stock.


They would tell you and you would notice if your phone was replaced - it would have new serial and 2FA apps won't work on a new phone without reregistration.

Most likely it took them a week to get a new battery for replacement shipped.


Awesome. Does planetscale vector support multi node indices (like Milvus) and even further blob store index storage which can be separate from compute, allowing to pay for compute on demand when queries are run?


Definitely yes to the first: the index implementation is fully integrated with PlanetScale's sharding layer, so you can scale horizontally as much as you need. This works very well in practice: the sharding layer, Vitess, is extremely well battle tested with petabyte-sized clusters in production, and our vector indexes are like any other table on the cluster, so it really scales horizontally with very predictable performance.

As for separating storage and compute: we don't do that. One of our key sells here is that this is vector data fully integrated into your relational database with ACID semantics. Very hard to do separate storage and compute and keep this behavior!


+1 . I have nothing to upgrade to from my iPhone 12 mini. Probably will replace battery and keep it running for couple more years.


Same boat. My storage is getting full (had a baby this year), so I’ll likely go refurb 13 mini with the biggest drive.


I’m missing the app already. Somehow I’ve got highly addicted to the idea be click article summary feature of Artifact. There was something highly gratifying of scrolling through articles’ titles and getting bullet point summary and not scrolling and reading through gazzilion of ads and pop ups most of the articles have nowadays. Recommendation part was more subtle, but working for me - there few occasional that I’ve learn something useful or interesting to me…

I would be grateful if somebody would suggest apps or service with similar article summarization functionality on a tip of users’ fingers.


Facebook recently started to show me this nasal stent product https://alaxousa.com/how-it-works/ Basically they sell expandable metal mesh tubes that are inserted though the nose and go down to throat when installed. And they are rather expensive - $395 and according to FAQ last up to 18 months.

I’ll ask my ENT about these stents when I’ll visit them next time.
