Just to be clear, I believe that wherever "seconds" was written, what was intended was minutes.

raspberrypi-kernel package is uninstalling chromium browser

How do I install chromium-browser? When I install raspberrypi-kernel it uninstalls chromium-browser. When I install chromium-browser it installs raspberrypi-bootloader-nokernel (which uninstalls the raspberrypi-kernel). What gives?

Re: Minibian vs Jessie Lite

Thanks for this excellent post. I was wandering whether to switch from minibian to Jessie (now stretch) Lite, and basically, I won't, because minibian is still smaller, because Lite contains a large bunch of stuff that either I won't use, or can download if I really need.

Re: Project idea

Certainly you could - but with a little more hardware. Your fans require 24v, and the Pi operates at 3.5v. You would need what is known as a motor controller http://www.yourduino.com/sunshop/index.php?l=product_detail&p=127 , which can basically amplify the power your Pi puts out to a higher voltage...

I recommend qemu. You should be able to run a number of VMs on your Pi, with a virtual Pi being the easiest (most efficient) target.

I would say your use-case is fine for a Pi. I use a model 2 as a file, print and web server at home, and have multiple devices connected at times.

My most recent Pi is a Model 3, and await the chance to get a couple model zeros. So so far, aside from the zero...

Re: What do YOU do with your raspi?

I have replaced a full sized server tower serving files, printer, scanner, several websites, blog site with a Pi 2. A 50 fold power consumption saving. At 12 c per KWh (Ontario), that is a saving of about $98 / year, which is close to what I paid for the Pi / Drive combo. http://blog.lbs.ca/technolo...

NFS root works fine, but I believe the use case here is for the Pi to be the server. That is what I am doing, and sharing the storage via NFS to other machines. In case someone is booting windows on my network, I also share the same exports using samba.

Re: Raspberry Pi with 1 TB external HDD 2.5

My preference was to go the other way - with a beefier power supply and a Y to power both the HD and the Pi from the same power supply. I used the Western Digital Pi Drive. The whole kit was less than half the price of the link you sent, and included an adequate power supply, an SD card, the 1TB dri...

WD are now selling just the nifty cable, so you could use your own drive. I am using the WD kit, and have just converted an old behemoth (AMD quad with 3 HD running raid5) sucking down 70 Watts 24/7, to a Pi 2 with a WD 1TB, using less than 10% of the power.
