aqui_c··on Making Green Hydrogen Viable (Webinar on Dec 4th)
We have been working hard on lowering the costs of production of green hydrogen to below the 1$/kg mark. A necessary step to enabling the commercial viability of green hydrogen.

We have developed technology that produces catalytic membranes with very low iridium loadings, limiting the costs derived from using an extremely rare metal.

We have also shown an extremely good stability, leading to electrolyser stacks that require fewer replacement cycles.

VSParticle's CEO will host a webinar on December 4th to answer all questions around the path we are following towards enabling the future of green hydrogen

aqui_c··on Is there a road for $1/kg of green hydrogen?
Hydrogen is a cornerstone element not only as a source of energy for transport, but because it enables the creation of many industrial derivatives.

The economics for green hydrogen are not particularly positive, and companies are pushing new tech to enable cheaper hydrogen creation through water electrolysis.

Is there a path to industrial-scale green hydrogen production or the context is simply not ready for it?

aqui_c··on How I feel quitting my own startup
Indeed, I've found some others in similar situations. Definitely a learning experience on which to build.
aqui_c··on How I feel quitting my own startup
Well, there's one product, one MVP, and a team of 8 full-timers... My biggest concern was the people, trying to find a situation that somewhat guarantees their short-term future and they can then go from there..
aqui_c··on How I feel quitting my own startup
Thanks! I try to stay as positive as possible, and looking forward to the new opportunities that'll appear.
aqui_c··on How I feel quitting my own startup
I left the startup I co-founded 4+ years ago. The entire process was an emotional roller-coaster.

My co-founders (and business partners), who are the majority shareholder, made it abundantly clear that the company was 'theirs'. They made decisions behind my back although I am the only founder working full time on the company. I felt alienated, undervalued, and frankly quite miserable for a while.

At some point, when this behavioral pattern started affecting other team members and I realized I had nothing left to do, it was time for me to move on.

I tried to write down how I felt, keeping it politically correct.

Do you think the Pope read Asimov's three laws?
aqui_c··on How to write a programming book
Indeed, there's no remark about it because I wanted to split the act of writing from the publishing of the book. The sentence on asking feedback was geared towards checking the ideas, having an overview of what you've written by someone else (which is not the same than proofreading).

All what you mention as missing, is part of my current ongoing process, and I still haven't learned nor tested enough as to summarize it.

I'm working on that. I just used a stock template for the website.

They are just links to Twitter, no JS involved on those fragments.
aqui_c··on Abandoning the Static Site
I also fell in love with static websites, I built all static, had pipelines for automatic deployments on changes... Just to develop my own dynamic solution a couple of years later. Just that I chose Django + Wagtail.

What I always thought would be a good compromise between two worlds is a way of editing files 'dynamically' and deploying them as pure HTML. Something like having a cache in place, but really using static files.

aqui_c··on From PhD in Experimental Physics to Independent Software Developer
It depends on whether you judge degrees from a purely utilitaristic view, plus PhD is closer to working than studying. If you work 10 years in a company, and then you write a book, would you wonder what are you doing with the title you earned at your job?

What does it mean for you to 'use a PhD'?
aqui_c··on From PhD in Experimental Physics to Independent Software Developer
I tried to summarize my path after finishing my Ph.D. in Physics. What was in my mind, and the things that made me focus on a niche that was obviously under-served. I had no tools to think about markets, value, money, but I think I managed to learn quite a great deal in a short time, and wondered who else out there is following a similar path.
aqui_c··on Ask HN: Is using Google Analytics on your personal site compliant with GDPR?
I know it is powerful, the questions is whether the OP is actually using them, or just server logs are enough. For a personal website, sometimes there's no need for too much info.
aqui_c··on Ask HN: Is using Google Analytics on your personal site compliant with GDPR?
What I meant by 'offloading' the responsibility is that building a GDPR compliant system can be cumbersome. For example, imagine you run a Wordpress blog (I am a bit outdated here, this may have changed in recent releases), there is no path for me to get all the information you have about me (for instance, all the comments done with my e-mail). If you keep server logs with IP addresses, building a system that gives me that information is also cumbersome. However, if you outsource those needs (for instance, to GA), and they do have GDPR compliant systems in place, then you have offloaded the responsibility of keeping these services in-place. Being GDPR-compliant is an added value for SOME solutions, it is up to the user to check whether GA is compliant or not.

Regarding the risk, I think the debate should go over what are you doing with your client's users data, giving it away to Google? Is it truly necessary? It is not only about risking a fine, is about being aware of what privacy means and what is it important.

aqui_c··on NetCDF or HDF5
Yes, I am. That is what made me wonder, why would you go for one or the other? What would it be the feature that makes you tip the balance towards one or the other?
aqui_c··on Ask HN: Is using Google Analytics on your personal site compliant with GDPR?
You have to take into account two different things. The ePrivacy directive and the GDPR. The ePrivacy directive is what generated the cookie popup you mentioned, while GDPR is tackling what happens with personal data once it is on someone's server.

You can check this article: https://gdpr.eu/cookies/

But it basically states that you should give your users the possibility of opting-out from tracking cookies, like the ones used by Google, and this is not GDPR, this is ePrivacy. To comply with GDPR, you should give your users the possibility to see their data, delete the data, etc. Since this is done by Google, it is their responsibility to comply with GDPR, and not yours (more or less... Let's say, it is YOUR responsibility, but you offloaded it to Google, which is compliant with GDPR apparently).

In any case, you should ask yourself why are you giving Google your users' data. Aren't your server logs enough to see who visits you?

aqui_c··on One month from concept to $1000 in revenue
My two cents in this discussion is that neither of the platforms tell how they get answers.

On IndieHackers, ideacheck has been asked several times what panel its used, but was never disclosed. The same is true for afteridea. The fact that both have big claims and no evidence supporting their statement is at most curious.
