Ask HN: Good hobby OS recommendations for learning
I've heard of Minix as a tool for learning about operating system design.Which OS is a recommended for study purposes? As in operating system design and architecture.

Even with our paltry electric use we are still getting high bills (UK)! Expense is the biggest incentive for us to get our electric use down.
If server farms have become a bigger polluter than the aviation industry, I see that as a challenge. Use the hardware as efficiently as possible. Caching layers could hugely reduce CPU use. Perhaps we could measure an app's power consumption aswell as bandwidth use?
A decade back I remember every office in a building I worked in (in the UK), leaving their machines on pretty much 24hrs. The building manager suggested the idea of cutting electric between certain hours, and people protested.
Phone chargers, desktops, monitors were all on. Probably for 16 hours of each day when no one was there. Even when people were there the machines were barely busy.
Computers could have been suspended to ram or turned off. I still see this even in offices with modern PCs that can boot quickly and suspsend to ram with ease (used to be touch and go).
Could spare CPU cycles be farmed out?
I'm glad to see better power saving settings in newer CPUS, and operating systems. But this needs to be better. Some mobiles can hold a charge for a week even with voice calls. Other smartphones are getting charged daily, some with negligable use. Charging batteries takes more power than you get back out.
Lots of small energy efficiencies could really help. Stuff like giving screen savers the boot, having sensible power defaults in OSs etc.
The bookmark/history manager could be better. It has no autocomplete/awesomeness in the search. It's actually quite an awkward UI.
It's not keyboard friendly. And their are odd inconsistancies. Should the default behaviour of clicking on a link open it in new tab?
Recent bookmarks and most visited are nice smart bookmark folder, these are useful but hard to reach in that tool. Some bookmark management feels a little like a black box.
At least you can tag bookmarks. Scrolling through a massive list of tags isn't much fun.
Like the bookmarks and history manager. There isn't anything particularly wrong with these data-table windows, but I don't really enjoy using them either. In some ways I think they should be at the heart of the browser.
I think a lot of people use tabs because bookmark management is so crap.
The only bit I resonated with was the similar sites suggestions. But you'd need a setting to setup suggestion services. There's a privacy concern with that.
Other helper features:
Pagination buttons were built into Opera driven off the rel=prev and rel=next, link elements. Navigation could further be ripped out the page window into a browser control. Searching sites and pages could be friendlier. Better form helpers needed. A good feed reader would be good. Tools to help read web content more simply (readability style) would be nice. Plus I like personalising the look and feel of my web browser ever so slightly, and even Firefox doesn't do that particularly well (it ignores some of my desktop theming).
So I think Firefox should really be thinking how to answer the question: 'How can we make it easier for users to consume web content?'. This has to go beyond the rendering engine. So actually a fatter featureful browser I think would be better - but with some very intuitive and simple controls.

I'm wondering if a Microsoft or an Apple employee has some rough estimate of the amount of Dvorak users compared to Qwerty and other keyboard layouts?It would be nice to have a list, I'm not even sure what would be at the top? US Qwerty?I'm not interested in the pros and cons of the layouts, just a rough estimate of adoption.Thanks in advance.
Now I'd personally prefer any book or text over the wire, to spending over £4 getting to my local library, where the seating is crap, and I can't hold a cup of coffee.
A few neighbours have colluded and perceive me to be a monster. I am male, and my partner (female) travels to work. I think they just don't get self-employment / working from home, and what looks like a role reversal.
I'm quite a friendly guy but their hostility (they have been quite mean) is starting to make me feel isolated and quite unwelcome in my own house and garden. When I'm actually quite happy to be on my own (providing I have enough external stimulous).
I bookmark liberally, from different web browsers on different devices. Sadly I still haven't gotten round to aggregated that data.
If I could dump the last days bookmarks to file quickly and easily, I could probably mock something useful up.
