Daughter wants me to make a game...

My daughter is 7 y/o and recently figured out that her parents can actually program *games* (we both have BSc in CS; wife is a web dev and I'm a sysadmin for a living). Of course she has no idea what this actually means in terms of time and work, but as long as she gets to be involved in the process...

Re: Using Raspberry Pi for Backups

You can probably set something similar up with Owncloud installed on your pi. I'm not sure how well the web interface runs on a 2B, but I've heard the synchronization works well. Owncloud server installed on configured on your Pi, then Owncloud clients on your windows machines. Port forwarding in yo...

E-book reader from a RPi Zero?

I once read an entire book (in Word-format) on my first smartphone. It had a 2.8" screen. I say that as a preface just to clarify that I know how small the hobbyist e-paper displays are and am fine with that :) But would it be feasible to make an e-book reader with a Raspberry Pi Zero, this display ...

Re: Can't seem to read USB HDD from RPi 2

Problem solved. Tip for those with similar issues: - If the HDD gives a few weak clicking sounds on connect, and the output of dmesg shows that a number of test write/read ops have failed, it's because the drive isn't getting enough power. Check that the line "max_usb_current=1" is added to the /boo...

Re: Can't seem to read USB HDD from RPi 2

I honestly don't remember if I've reformatted since I bought it... Could be either FAT32 or ext4.

Of course an exotic filesystwm could lead to mount issues, but would that explain the dmesg output? I seem to recall similar output from years ago, but then I had forgotten so set max_usb_current=1

Can't seem to read USB HDD from RPi 2

I did this before a couple of years ago and got it to work, but apparently missed something this time? I have a 2.5" HDD that I just connected to my RPi 2 (no external power source). I can't seem to mount it, and dmesg reports the following: [81015.577947] usb-storage 1-1.5:1.0: USB Mass Storage dev...

nobbit, That's a subtle thing you did there. Your post was about "...power from one outlet". Which we naturally take to mean one mains power outlet from the wall. Which is 250 volts rated at 13 amps current draw in the UK. Which is more than 3 KWatts. Enough for three thousand Pi. Or perhaps one th...

Re: How many Pis can I power from one outlet?

What got me thinking about this in the first place was USB charger. Because it says it can give up to 2.4 A in each connector, but only a maximum of 3.4 A over all three connectors combined.

But I guess the answer to that would be "find another charger" :)

I may sratch the MUD idea, then. Building a game world seems like *a lot* of work.

In case I do decide to write a setting, I assume some sort of markup language or even programming would be used?

Any good MUDs out there that I can run on my pi?

Some friends suggested that I should host a MUD on my pi that we can all play on. I've googled a little and found several MUD engines, but it's not obvious to me whether any of them come with any game content.

Anyone knows of a full MUD game that I could host?

Re: OwnCloud off a USB HDD

Have you checked your web server settings? I'm assuming you mean that you're uploading via the web interface. In that case the web server's maximum POST size limit could be the culprit.

For example, check this

Re: PHP page to execute shell script?

You can probably do it with a "system" or "exec" call from php (not sure exactly what it's called in php, but it's common in most programming languages.

Alternatively you can google "CGI" or "Common Gateway Interface".

How long does it take for the script to run?
