spotman··on High Available Mosquitto MQTT on Kubernetes
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.

spotman··on Ask HN: Get a job or double down on my own business?
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.

spotman··on Truth Behind Neo4j’s “Trillion” Relationship Graph
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··on Oatly loses trademark battle against British farm over oat milk
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.

spotman··on DoorDash removing 1-year cliff for equity grants
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.

spotman··on DoorDash removing 1-year cliff for equity grants
Not really true. Have achieved multiple companies removing the 1 year cliff for me.
spotman··on Eddy Cue wanted to bring iMessage to Android in 2013
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··on Apple presses ahead with aim to replace paper passports and ID with iPhone
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··on Launch HN: Charge Running (YC W21) – Social running app with real-time coaching
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!
spotman··on Elon Musk admits Tesla car quality flaws, says mass production is “hell”
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.

Ally Bank
spotman··on Simple Bank Is Closing
Ya same here. The name issues, the killing of the ability to auto mail paper checks (bills), and seemingly over time extremely strict policies on everything from deposits, to addresses, Simple has already been going down hill for awhile.

Personally I have gone out of my way to submit polite and concise feedback, as I really wanted them to win. I used to be so happy here as a customer but inch by inch it had just become overwhelmingly unpleasant.

So over the last year I have slowly moved most of my banking to a competitor, and which as a whole is bigger and does have as smooth of a UX, but has been flawless with actual banking features. The support has made me feel like they actually want my business rather than being a nuisance to them.

It was good while it was good simple, I imagine running a bank is not easy, best of luck to everyone that was a part of it in their next venture.

spotman··on A container ship lost a record 1,800 containers
Often products with batteries in them. But also products with chemicals or generally products that cause could health, safety or fire concerns if not handled properly.
spotman··on Strava raises $110M, growth rate of 2M new users per month in 2020
Good for Strava. In my community of athletes Strava is the gold standard and there is really nothing else quite like it that is compatible with more than one brand of device and offers a similar feature set.

Probably about 1/2 of my friends are paid members. Since they changed their billing model/feature/plans earlier in the year, more people in my circle started paying and I can not think of anyone who left.

While there can be some frustrations with some of the segments, it really varies heavily sport to sport and area to area. In trail running segments where I am it's pretty rare to find a completely unbelievable segment entry that screams someone is cheating. But at the end of the day often you are filtering the segment results down to your followers or clubs list.

Overall I find Strava to keep me more engaged in friendly competition than other-words and the premium features do a good job of adding actual value in terms of another view/opinion in your training status.

Having said all that, my circle of friends are not your casual athletes.

spotman··on Ethereum Is a Dark Forest
and less strong systems , also, become black boxes for other systems...
spotman··on Ask HN: What's the worst piece of software you use everyday?
Slack. Frustratingly slow and bloated. Company is addicted to it.
spotman··on Ask HN: What’s your laptop?
Agree. My sixth gen happily runs fedora daily. I have had it for about a year, no complaints.
spotman··on How We Designed the Librem 5 Dev Kit with Free Software
There is some beginning work being done to have libhandy wrappers in rust. I have gotten their qemu environment up and running and will be tinkering on rust+gtk apps which I hope has a future in this ecosystem.

But yea by default it appears most stuff is c and gtk right now.

spotman··on Librem 5 dev kits are shipping
regarding date and supply chain uncertainty i would tend to agree.

in this case however, they do sell laptops. so, they aren’t completely incapable of supply chain.

depending on if the laptop is really an in-house design, or not, they may be certainly going from a very basic to an extremely sophisticated supply chain.

or it could be that it’s not an in-house design fully and someone else is doing the supply chain and general design of the hardware.

the date is extremely optimistic or the handset hardware is much farther along than is obvious from the content on the site.

having said that i am a backer and can’t wait. vote with your dollar i suppose.

spotman··on Nerves – Craft and deploy bulletproof embedded software in Elixir
> and the BOM cost is way less than I used to pay for Arduino

one would hope so, arduino is a retail packing of other chips into a kit.

spotman··on Why I'm declining funding from Ruby Together
Sounds like a good time for a fork of bundler.
spotman··on Jepsen: Aerospike 3.99.0.3
can you comment on ease of operations between NDB cluster and aero spike? from my experience NDB cluster is pretty difficult. curious if aero is the same.
spotman··on The full-time job of keeping up with Kubernetes
Writing your own QT sounds like a long road however that would likely not be as fast as making work arounds or providing bug reports or patches.
spotman··on Ten days in Shenzhen
Worth noting AT&T has great partnerships in these areas and I get 5 bars of LTE in all of these cities for 10 bucks a day when I am here. Also there is plenty of places to buy sim cards if your phone is unlocked.
spotman··on Ask HN: What do you use/do for keeping your eyes healthy
drink lots of carrot juice, it’s high in vitamin A
spotman··on Leaving htop running freezes macOS High Sierra
I came for the incredibly useful touchbar and stayed for the cascade of un-exit-able menus that occur when you try to combine the awesome powers of the fingerprint reader and keychain.app
spotman··on Reading privileged memory with a side-channel
Pretty sure that its not limited to js:

https://gist.github.com/ErikAugust/724d4a969fb2c6ae1bbd7b2a9...

Its a technique, not a flaw in js, from my understanding

spotman··on Apple is close to acquiring Shazam, sources say
welcome to basic audio design practice in place for commercials and marketing for about 30 years. the approach hasn’t changed only it gets easier.
spotman··on Choosing between names and identifiers in URLs
that’s funny. i have the exact inverse problem. when i ask siri to call my wife ( by her first name only ) it gives me a list of two to pick from, whereas my car does the opposite and calls my wife.

darn computers!
