when dealing with long lasting TCP connections, why add that extra layer of network complexity with k8s? I work for a big IoT company and we have 1.8M connections spread across 15 ec2 c8g.xlarge boxes. Not even using a NLB just round-robin DNS. Wrote our own broker with https://github.com/lesismal/nbio and use a packer .hcl file to make the AMI that each ec2 box boots. Using https://github.com/lesismal/llib/tree/master/std/crypto/tls to make nbio work with TLS.

Having worked at multiple IoT companies with many millions of connections. This is the way.

People tend to overcomplicate things with K8S. I have never once seen a massively distributed IoT system run without a TON of headache and outages with k8s. Sure, it can be done, but it requires spending 4-8x the amount of of development time and has many more outages due to random things.

It's not just the network, its also the amount of config you have to do to get a deterministic system. For IoT, you dont need as much bursting (for most workloads). Its a bunch of devices that are connected 24/7 with fairly deterministic workloads, that are usually using some type of TCP connection that is not HTTP, and trying to shove it into an HTTP paradigm costs more money and more complexity and is not reliable.

If you are open to sharing, what is your business?

Otherwise, "it depends"... If you get a job, you can also be laid off.

But if you are able to get a job, while also keeping your business going, this seems to be the best way to financially insulate yourself - as long as you don't let your business actually stagnate too badly, which will only make the economic environment likely impact it more.

We had the same experience. Ended up converting the entire database in Neo4j to relational tables in postgres.

Yup, same here. If you have any moderately large data set and do manage to get it loaded , then it will break with only a light graph traversal of 3 layers deep. Played with this for a couple weeks but eventually realized this is not for a large data set.
spotman commented on Oatly loses trademark battle against British farm over oat milk   bbc.co.uk/news/uk-england... · Posted by u/vanilla-almond

I used to think that. Then I started wearing a continuous glucose monitor (levels) for longevity reasons. Holy crap, a latte with Oatly spikes my blood glucose like crazy compared to whole milk. There’s way more sugar in there vs fat and it really causes a strong insulin response. That isn’t the kind of thing you want to be consuming long term.
spotman · 4 years ago
Yes agreed. Oatly is horrible for you. It's one of the worst Oat milks they sell in my store. (when comparing by nutrition facts).

It is so bizarre this alternative milk that goes around. I am totally onboard with finding an alternative to save cows from inhumane practice, however, very little of the alternative milk that is out there is anywhere near as healthy as normal milk.

Meanwhile anyone can produce any type of alternative milk and people think they are buying health food.

At high-quality VC-backed tech companies? I guess it might be possible it you were super early.
spotman · 4 years ago
It’s happened multiple times for me, all with extremely well known VC backed companies. Once at later stage, but applying for a very senior role, and another at an early stage, where there was a good fit.

It can be a tough sell, and recruiters are trained to just say no, but persistence pays off. Same thing applies to getting jobs in general. If you aren’t persistent in your application process and aggressive in your negotiation process, you simply won’t have the best outcomes. It just becomes easy to turn you down.

"I declined an offer from a known and well funded startup because of a one year cliff on equity"

You might as well not bother interviewing at any startups if this is a deal-breaker for you. Whether you think it's fair or not this is an extremely standard term and no company is going to alter their employee stock grants on a one-off basis.

Not really true. Have achieved multiple companies removing the 1 year cliff for me.
spotman commented on Eddy Cue wanted to bring iMessage to Android in 2013   theverge.com/2021/4/27/22... · Posted by u/embit

> I am concerned [that] iMessage on Android would simply serve to remove an obstacle to iPhone families giving their kids Android phones.

We're an iPhone family, but damn is that lame. How about: make the best product. Don't coerce people into buying an iPhone.

It drives me crazy how fractured messaging has become. Here's a recent example. My non-technical aunt tried to send a group iMessage to my wife and me. For me, she used an email address tied to my iMessage account. But for my wife, she used her Google Voice #. Now what you need to understand is that iMessage allows you to associate one or more email addresses with your account, but only a single phone #, which has to be your carrier-assigned #.

So now she's trying to send an iMessage to my email address (which would have shown up in blue) and my wife's Google Voice # (which would have shown up in green).

Well, here's what apparently happened. iMessage handed this off as an MMS to Verizon. Verizon's MMS gateway sent me the message via email, as a text attachment. My wife got the message in the Google Voice app on her phone.

What an f'ing mess.

I've turned off "Send as SMS" and "MMS Messaging" on my iPhone so I don't make this same stupid mistake.

I'd use WhatsApp for everything, but, Facebook. (I tried Signal. I found it to be pretty sub-par for everyday messaging.)

spotman · 5 years ago
Telegram is one potential answer. I find it to be the fastest messaging platform , and super reliable. Not to mention their desktop apps are not bloated, and message history, drafts, etc sync really well. (note - there is also a secret mode that works like signal, that also doesn't sync message content, which is parity with signal)
spotman commented on Apple presses ahead with aim to replace paper passports and ID with iPhone   appleinsider.com/articles... · Posted by u/CharlesW
spotman · 5 years ago
Makes sense that some people will not be a fan of this.

Personally however this would be awesome. It is extremely rare I don’t have my phone. already any passport control area is digitally scanning my passport so there is not really more privacy concerns. In addition I imagine a lot of us use the plane ticket features of iphone already, so not having to also separately get my ID out would be great.

Seems like this is long overdue.

spotman commented on Launch HN: Charge Running (YC W21) – Social running app with real-time coaching    · Posted by u/mknippen
spotman · 5 years ago
Hi - very cool idea! Will probably try it out. Apologize if this is on the site (could not find it) but do you plan to offer any features to "meet" local runners in person? I am always trying new run clubs, and some have stuck and some have not, but I would absolutely LOVE a way to meet local runners that run similar terrain/fitness levels as me. Thanks!

It's a car company from California, not Detroit.

Most major automotive and ev companies use tools such as environmental chambers to do phases of R&D. (quite possibly all do but obvs can’t confirm, but do have first hand knowledge of several major companies adopting this) Even companies much smaller than Tesla.

Would be shocked if Tesla did not have this capability.

So who knows if this is part of their testing and validation, but it is not true that you can’t test for different environments than where the core design takes place. It is extremely common to do this in rapid fashion without having to transport things to an alternate climate.
