Ask HN: Why isn't there a React Native browser yet? - <AUTHOR> In development mode, react native works like a glorified web browser but instead of web components it renders native components. Why isn't there a browser (and a server/package manager) which brings native to the web. Instead of a hardcoded IP for the package manager we have an address bar which fetches the react code and renders it. Is performance the concern? Or does HTML win because of smaller code footprint? What has stopped Facebook and/or others from building the native web. <comment><USER2> Security and Sandboxing. You would have to reinvent so many security protections.

<comment><AUTHOR> I think it won't be a big challenge as browsers have solved this. We would need to bring it to the "react-native-browser".

<comment><USER2> Running remote code without real trust chain is not a big security challenge? I think you strongly understemate what browsers do. Browsers solved this over many many years, when is the last time you heard anyone starting a new html engine from scratch?

<comment><AUTHOR> The same ideas of browsers need to be implemented here. We could ask for permissions like browsers do for location. While I can give multiple reasons as to why no one starts a new html engine from scratch, it's no reason why we shouldn't.</comment></comment></comment></comment>


Introducing Google Earth Engine - <AUTHOR> http://googleblog.blogspot.com/2010/12/introducing-google-earth-engine.html <comment><USER2> Very interesting.

Although I have problems understanding how "building a more sustainable future" falls in line with Google's business direction. I noticed that this is a .org thing but still seems like it requires a lot of resources. So I guess my question is, what's in it for Google?

I have a growing data set of environmental data that combined with the historical imagery and analysis will make for a very nice paper.</comment>


High Times Beckon for Using Hemp to Build Houses - <AUTHOR> https://www.nytimes.com/2018/01/29/science/hemp-homes-cannabis.html <comment><USER2> A must watch for the impact of construction and infrastructure in the world is the documentary Sand Wars. They lightly mention alternatives such as hemp blocks at the end. Never thought sand was so problematic and important (just behind water and oil).

</comment><comment><USER3> Another use of hemp is for clothing.

I searched for years to find a great winter coat minimizing animal products and fossil fuels. Finally, I found Hemp Hoodlamb's parka [https://us.hoodlamb.com/collections/fw17-man/products/aw17-m...](https://us.hoodlamb.com/collections/fw17-man/products/aw17-mens- nordic-parka) which fits the bill and keeps me warm.

The company has a couple videos showing their hemp production in China.

On another note, from the article:

> _Getting a mature plant in just a few months — with less fertilizer than > needed for industrial crops like corn, and without chemical fertilizers or > bug sprays — makes the potential for profit huge._

That's not how profit works. Fast growth may make the potential market size huge, but without barriers to entry, competition will bring profits down.

</comment><comment><USER4> If memory serves, hempcrete's physical characteristics are such that it's only good for shorter buildings. We won't be building any dense housing out of the stuff.

So it's a very useful building material for rural areas.

<comment><USER5> Absolutely, its compressive strength (~1 MPa) is so low that it's better to think of it as rigid insulation that anything structural or load bearing.

<comment><USER6> For reference that's less than dry wall...

<comment><USER7> Well that might be ok if you make it thicker. Eg straw bale walls for housing. Also only good for about one story but it's nice to have alternatives.

Russian artists wear anti-facial recognition make-up and get arrested - <AUTHOR> https://observers.france24.com/en/20200214-russian-artists-facial-recognition-makeup-arrested <comment> m-p-3 Now I want to see people wearing QR codes makeups. Imagine if someone found a way to attack facial recognition with a QR code-based payload.

<comment><USER2> But... facial recognition system doesn't read qr because why would it?

<comment> m-p-3 I was just using QR as a example method of injecting data from an analog/real world representation.</comment></comment></comment>

Interview with the Google Pixel 3 Camera team [video] - <AUTHOR> https://www.youtube.com/watch?v=W-bJg2L2HxA <comment><USER2> Slightly off-topic (apologies): I love DPReview. They are one of those review websites that don't give a shit about webdesign or new trends. Their website still looks outdated and I _really_ love that.

Most importantly, they year after year deliver deep technical information about cameras, lenses and sensors that very few other review websites cover. Objective, unbiased and to the point.

We need a DPReview for audio products. It seems like the entire Audio review process, methodology, the people behind it and the consumers are all insanely annoying, deluded and completely out of touch with objective reality. I never read audio product reviews for this reason - it lacks scientific truth.</comment>


Microsoft's SideSight: Something Apple Should Watch - <AUTHOR> http://www.gearlog.com/2008/10/microsofts_sidesight_something.php

<comment> kyle-burton The only quirk I see, as opposed to multi-touch (iPhone) is that you'd have to set this device down or hold it in very awkward ways. If you're at a desk that's fine, but it'd lead to precarious situations with not holding on very securely to your device.

<comment><USER2> Agreed. I know it's a Microsoft research project, but playing devil's advocate:

What's the point of a _mobile_ device again?

Oh, right. :)

<comment><USER3> well here's what i see with the tech, forward about 5 years.

mobile PC eyewear. you're walking around doing whatever it is you want to do, and to access your PC systems reach out in front of you and make gestures. the IR emitted from the glasses reflects and takes note of your hand/finger positions and interprets your actions as interface operations.

far-fetched? maybe i watch too much power rangers

</comment></comment></comment><comment><USER4> Neat but I can't imagine what useful features would require me to wave my fingers around the phone instead of touching the screen.</comment>


Ask HN: Recommendations for a Password Manager - <AUTHOR> I am looking for a password manager that works
- offline
- locally, without an account
- ability to backup
- mac app
It would be preferable if it is open source.
Any suggestions are welcome. <comment><USER2> 1Password with the one-time $50 software license + its local WLAN synching functionality + automatically backing up your hdd/ssd locally.

<comment><USER3> Is this still true?

As far as I can find on their website (and the reason I switched to self hosted Bitwarden) was that they switched to a subscription only model.

<comment><USER4> I'm paying $35/year but I think it's still worth it. Solid integration with my Mac and iPhone.

</comment></comment></comment><comment><USER5> Yep, Bitwarden gets my vote too. I switched from LastPass (after 5 years of use) earlier this year and am very happy with it so far. Works great on all my devices (Win, Mac, Android).

<comment><USER6> Does Bitwarden work offline? I thought it needed a server to sync to

<comment><USER7> It does work offline and it does need a server to link to. It has a cached copy of your stuff, all still protected by your master password.

</comment></comment></comment><comment><USER8> KeePassXC [https://keepassxc.org/](https://keepassxc.org/)

<comment><USER9> I use this too. Keepass on windows, keepassxc on Linux and keepass2android on Android, with the db synced to all my devices via Nextcloud.

The db is encrypted via a passphrase plus a keyfile that I copy manually to each device (that is, it's not synced with the db).

<comment><USER10> I have a great fear of things like the Android/IOS app from the store being compromised, resulting in my passwords going to someone. Do you do anything specific to overcome such fear?

</comment></comment></comment><comment><USER8> Bitwarden is not offline by default - it stores you passwords in the cloud and keeps a local copy. So you can access it offline but you need online access to edit it. See: [https://www.reddit.com/r/Bitwarden/comments/9yv32e/can_bitwa...](https://www.reddit.com/r/Bitwarden/comments/9yv32e/can_bitwarden_work_offline/)

<comment><USER11> Sure, it depends on your definition if "offline". My guess is that most people asking for an "offline" password manager are not actually offline much of the time, but specific use cases may vary!

Keepass is nice, it's what I used before Bitwarden. It's not great at syncing across devices or sharing passwords with others, though.

</comment></comment><comment><USER12> I use pass [1].

It's simple, terminal based, easy to back up, and open source.

[1] [https://www.passwordstore.org/](https://www.passwordstore.org/)

<comment><USER6> I haven't compared them recently, but gopass [0] is compatible with pass. It has a few more features that makes it nice to use with other people.

[0] [https://github.com/gopasspw/gopass](https://github.com/gopasspw/gopass)

</comment></comment><comment><USER13> Master Password [0]

\- It's open source

\- Mac App does work well (also available as CLI software)

\- Possible to make backups

\- Works offline (also a Webversion so you have Access to passwords on any machine with internet access)

\- No account needed

[0] [https://masterpassword.app/](https://masterpassword.app/)

</comment><comment><USER14> How about Psono? You can host everything on your own (so I assume that would count as "offline), client side encrypted and its free and open source.

Full disclosure I am the main developer behind Psono.

</comment><comment><USER15> I am looking for a password manager for my team as well. Keepass on a shared drive is not ideal anymore. Looking forward to seeing recommendations.

</comment><comment><USER11> I really like BitWarden: [https://bitwarden.com/](https://bitwarden.com/)</comment>

Is De-IT-ization a business opportunity? - <AUTHOR>

<comment><USER2> De-IT public schools. There is too much emphasis (money) on networking a school and not enough money spent on bringing the teachers on board with using their computers for teaching. A school near to me spent 350K on new updates to the network and only three teachers at the school use it for something other than posting their grades. Pitiful. Start a training business for teachers to upgrade their skills.</comment>
