This is one of the frustrating parts of database software. Where can information about the ways to optimize these parameters be found (outside of random posts scattered around StackExchange)?


so true. Either you have lots of experience working with specific databases to setup/optimize queries, and you know what works best through personal blood, sweat and tears, and/or you have intimate knowledge of the inner workings of the database architecture/implementation and know the theoretical best approach to structure your schema/queries.

But even then, hardware/networking performance and tuning can throw a wrench in the most seasoned/knowledgeable approaches. Users can further bring otherwise solid setups to a grinding halt with unanticipated use-cases.

The only hope when you hit these inevitable road-blocks is that you're working for someone that appreciates the difficulty of the problem.


Suggesting someone waste $870 by buying 100x as many as they need is not helpful. Your numbers for the ESP are wrong - I can get one for less than $2. https://www.aliexpress.com/item/Free-shipping-ESP8266-serial...


Yea, even the ESP32 on a more user friendly package like NodeMCU or WeMos are still under $5. So he appears to really be downplaying the markup.


If you think you can do better, please do! I will be sure to buy plenty when you deliver your cheaper version.


Somebody reads reddit.


Survivorship bias.


sure, but. what things built in the last 20 years do think most likely to last for 2000? I'm not sure I can think of any. Parts of a big highway maybe?

This should provide some information about the durability of stone. I am not aware of similar experiments for other materials.


I imagine the Brooklyn Bridge will be standing for at least a few hundred more years unless it goes underwater. Plenty of buildings in the mountains should survive.


The money funding SpaceX could hardly be allocated towards sustainable colonization of Mars in a more efficient manner. If you can think of one, please email Elon.


Sure, SpaceX has good business plan. That's the point. Building rockets only for a future Mars voyage and not making any money along the way would be a bad way to do it.

By contrast, fusion will only be a scientific research project for many years and many billions.


That's just the way it works. It cost a lot of money to develop rockets in the first place. Your comparison is simply not very meaningful.


My point is there is a big difference in how much money gets tied up for how long. (Capex.)


There are probably not many women here because it's not fun to be on a forum full of finance-obsessed manchildren and brogrammers unless you are one or identify as one. The actual benefits from being on HN are basically null, yet most men who use it think it'll improve their careers. It won't, but it helps sama and paul graham.


It sure is rich seeing a person who thinks hacking should be punished with death complain about webcomic layouts.


Not sure what that has to do with anything, I was posing a question.

Maybe it’s time to burn this account, doesn’t seem like it will be useful for constructive discussion anymore.


Please don't cross into incivility even if someone else has been breaking the rules.


Maybe it's time to burn your abominable attitude.


You've unfortunately posted lots of unsubstantive comments to HN, and here crossed into personal attack which is even worse, so we've banned this account. If you don't want to be banned, you're welcome to email hn@ycombinator.com and give us reason to believe that you'll follow the rules in the future.


relevant username.


Just because something new-ish exists doesn't mean it's the root of something society-changing. Bitcoin might be a steam engine.


> Bitcoin might be a steam engine.

I think it's fairly safe to say that steam engines revolutionised society (the industrial revolution and all that), arguably more so than those engines that replaced it.


Sure. But they never worked on airplanes, and they're only a distant ancestor to the jet and rocket engine. You don't see people investing in steam engines these days.


> Just because something new-ish exists doesn't mean it's the root of something society-changing. Bitcoin might be a steam engine.

this is a great comment, i can interpret it at least two entirely different ways.

by "might be a steam engine" do you mean that bitcoin might be one of the key drivers of a major process of economic/industrial revolution?


I mean it might be completely obsolete in five years. It has caused a great deal of innovation, even if much of that doesn't come to fruition.


Bitcoins are tulips.


Or Cabbage Patch dolls


Cabbage Patch Kids and tulips wear out and disintegrate like any other organic matter. We will be lucky if bitcoin wallets from a decade ago are able to be cracked a thousand years from now.


How original. I imagine you can show how the tulip craze fomented great innovation in the floristry field, and spawned a few actually good products despite being inherently misguided?
