IpV8··on Ask HN: Are you using AWS Lambda in production?
I've used serverless to deploy, works super well. I'd like to try out SAM and see how it compares.
IpV8··on Ask HN: What are the most interesting emerging fields in computer science?
Distributed power electronics are inherently dangerous. If you have a surplus of power and your neighbor has a deficit, it is desirable for the two systems to communicate to send power from you to the neighbor. If a bad actor can leverage this system to tell everyone to send all of their power to the grid, they could easily damage the infrastructure in a very costly way.
IpV8··on Ask HN: What are your heuristics for deciding which HN links to click on?
I click on most things that start with "10 ways to..." and then immediately regret it. I then repeat the process with "Kubernuts (is/isn't) the best thing ever" and then immediately regret it. And then I click on the comments of any article that I have industry specific knowledge on and tell everyone why their opinion is wrong without reading the article.

Gosh I need a new way to kill time.

IpV8··on Ask HN: Mass department walkout
In my experience the hemorrhaging will continue. When people see this they start looking for jobs and continue their time with that company limited.
IpV8··on Ask HN: What is your rate?
15% more than what I'm making now.
IpV8··on Thailand cave rescue: all 12 boys and coach successfully rescued
Agreed. The man is a master of public relations.
IpV8··on What's the Minimum Number of People for a Generational Ship to Proxima Centauri?
Good point. We'll need to send some robot mothers too.
IpV8··on What's the Minimum Number of People for a Generational Ship to Proxima Centauri?
0. Just have a robot incubate some clones once it gets there.
IpV8··on Ask HN: What are the emerging niches in computer science
SLAM
IpV8··on Ask HN: Does the term artificial-intelligence drive you up the wall?
Yea! And while we're at it, I'm livid that we're still calling them REfrigerators! WAKE UP SHEEPLE!
IpV8··on How do you invest your disposable income as a tech worker?
Very powerful. Would be useful to see more explanation on some of them though. Exe what the heck does the last one mean?
IpV8··on Gitlab is not the only GitHub alternative
Bitbucket works but their web interface is slow as hell.
IpV8··on Ask HN: Are you working on interesting technical problems?
I do. I gave up many higher paying opportunities and took risks. It is tough to turn down a good offer without a better alternative just because the work is displaying data on a web app. I've found the trick is find interdisciplinary teams. Look for jobs building medical/scientific research equipment, or renewable energy, or robotics. Also, the more experience that you get building CRUD apps, the more inertia your career has in that direction. Go to meetups, build cool things and show them off. Look at R&D grants from your state and cold email those companies. It will take time, but good jobs are out there.
IpV8··on Ask HN: What can you do today that will be significant in 1000 years?
Beyond good and evil? Changed the way all future philosophers defined and thought about objective morality.
IpV8··on Lyme Disease Is on the Rise Again
I grew up in Connecticut, not far from the town of Old Lyme where the disease gets its name from! Most people who spend any amount of time outside there know the symptoms well and doctors give away doxycycline prescriptions like their going out of style. I've gone through it three separate times. If you catch it quick, the antibiotics crush it and you're on your merry way. Ignore it and you'll suffer for life.
IpV8··on Ask HN: What do you enjoy most about your job?
I work on communication systems for cutting edge home renewable energy systems. It has its good days and its stressful days, but overall engineering solutions to complex and meaningful problems rocks pretty hard.
IpV8··on Ask HN: What's your top 5 questions to ask your prospective new employer?
These are really rock solid questions. I would also add something about the business side. I like to ask some variation of "who pays". Are they making money off of contracts, implementations, investors, grants, etc. This segues into questions about the motivations of the owners. Are they trying to grow and then sell? IPO? Are they happy to run a small company indefinitely? Do they have to answer to venture capitalists? Shareholders? The state? etc.
IpV8··on Ask HN: How to motivate employees?
Perhaps they are bored. Can you give them something interesting to work on, or totally outside their current responsibilities? I find I get bored when my job gets too repetitive, and a good solution is a big general directive like "go to some conferences and come up with a market research presentation for our company" or have them hire a replacement for themselves to free up time for other types of work.
IpV8··on Ask HN: What is the purpose of Life?
"Everything that we know and love is reducible to the absurd acts of chemicals and there is therefore no intrinsic value in this material universe"

"Hypocrite that you are for you trust the chemicals in your brain to tell you they are chemicals. All knowledge is ultimately based on that which we cannot prove

Will you fight? Or will you perish like a dog?"

IpV8··on How Windmills as Wide as Jumbo Jets Are Making Clean Energy Mainstream
I was speccing to the 10-15 kwh range. Maybe you can get it for cheaper, but with the use case he described you're talking about a substantial continuous rated power and surge power. How many amps can your $10,000 50 kwh battery push? Also I'm including installation, warranty, etc. It would honestly probably be more than that because he'd likely need a more expensive inverter or 2 inverters to deal with that kind of load (I doubt his AC unit and dryer are DC).
IpV8··on Ask HN: What are the smartest people you know working on?
Getting people to click on advertisements.

Not sure why that's an either or?

Do you believe the batteries should be subsidized - Yes, I think that they should be subsidized now. I normally don't like government involvement in markets other than protecting against externalities, but in this case I believe that subsidies can expedite innovation in the area. Once the market exists and the technology moves far enough along, I think that we will be able to slowly remove the subsidies and battery systems will be cheap enough to warrant their place in the market without. Also I strongly believe that the faster we move away from fossil fuels, the less lives will be lost to climate change.

instead of the power going back into the grid - Not sure what you mean here. People sell back to the grid all the time. A battery backup system in sell mode is essentially another power plant. Great!

You're going to be closer to $10,000 for that kind of storage. Probably not economical for your use case unless you get good rebates and electricity is expensive where you live.

Source: I build home battery backup systems for a living.

The types of people buying batteries today live in places where arbitrage is an option (california, hawaii), or where the grid is frequently or always down (puerto rico)... or rich people who want to be energy independent. They generally haven't made it to the general public yet, but cost is coming down every year and utilities/incentive programs are spreading.

IpV8··on How Windmills as Wide as Jumbo Jets Are Making Clean Energy Mainstream
The price of buying/selling to/from the grid is different at different times of the day. Artificially set by the utility. Different utilities have different rules. In some you can take advantage of the arbitrage if you have a battery; buying during the day and selling in the evenings.

Exe here is San Diego's pricing from the perspective of consumption only: https://www.sdge.com/residential/pricing-plans/about-our-pri...

California and Hawaii have already implemented price curves that make purchasing solar + storage viable for homeowners. As more states adopt these policies and more homeowners adopt batteries the duck curve can be solved. Also battery storage gives the added benefit of not needing a gas generator when the grid goes down if you have an islanding system!
IpV8··on Ask HN: Best way to input data to a RasPi, from browsers on the same LAN?
I've done similar things with python/flask. My experienced tip, if you try to do an ad hoc network and have people connect to that without passing the internet through, prepare to get f'd by apple: https://discussions.apple.com/thread/7705927?page=3

If you want to host it on the lan just play with IPtables to get your port through and host a little web server. Shouldn't be too complicated. Look in to gunicorn for a production capable flask server. I have used Monit to keep gunicorn alive as a second line of defense. You could use init instead if you prefer.

If this is over your head let me know and I can break it down to more detail.

IpV8··on Ask HN: After earning how much money are you planning to retire?
Wow thats a ton!!! I suppose you must live in a higher cost of living area than me.
IpV8··on Ask HN: Has Spotify been breached?
Definitely possible. I don't do completely unique passwords, but do do a tweak on a standard password that was unique to my spotify account. Also a quick google of 'pastebin spotify 2018' shows quite a few lists of emails and passwords posted rather recently. I suppose there is no way to know one way or another, either way I just went in and randomized my bank/email passwords to be safe.
IpV8··on Ask HN: Has Spotify been breached?
Just happened to me again. Now all of my playlists are gone and replaced by trap shit.
IpV8··on Ask HN: Has Spotify been breached?
Happened to me last week. Music stopped playing, said it was playing on some iphone, and now all of my recently playeds are bands I've never heard of. I changed password and it hasn't happened since. Something fishy is going on.
