oculus rift dk2 win10

I bought the DK2 on release and had great fun with Elite Dangerous and the demo scenes. Then I lost interest for a while. In the mean-time installed Win10.

Now, I considered buying the next Oculus device as its resolution is higher and there is an ED extension available; also more games are compatible.

My background: Master of Science in Physics from London; PhD in Aero from London. I simulate acoustics using the finite/boundary-element method and flow using the finite-volume method. I built a high-performance cluster at work and use it / maintain it daily. I know computers. Those people at Oculus have been promising Win10 drivers for this hardware, literally, for years.

Not one byte to that effect.

I've rolled back my drivers to win7.  Spent man days on this waste of time. No joy. Demo scenes work: amazing hardware! But those people didn't release Win10 drivers.

I will never buy from Oculus again. They took my few hundred pounds and I got a few months of gameplay and now, no support.

Disappointing performance.  I will avoid you and any of your spin-offs in the future. My money will gladly go elsewhere.

People reading this: don't waste your time rolling back, reinstalling, dicking around. Go smell the flowers, spend time with family, see new places. These people will take your money, waste your time, and leave you hanging.

$ sudo mount /dev/sda2 /mnt/sda2
mount: wrong fs type, bad option, bad superblock on /dev/sda2,

       In some cases useful info is found in syslog - try
       dmesg | tail or so.

The offset here is 1001470*512 bytes = 512752640 to get to the second partition:

sudo mount -o ro,loop,offset=512752640 /dev/sda /mnt/sda2/

If using an image file, use the filename instead of /dev/sda

Yet another backup rsync script. This one works on Ubuntu, 2016 September.

For some reason, my old backup scripts aren't working. A simpler approach is to add this sort of thing to a script called by cron:

rsync -vrmxz --progress --include='*.ipynb' 
  --include='*/' --exclude='*' /home/me /mnt/J/backup/

which starts at the current directory and works through all sub-directories, grabbing each .ipynb file and copying it to /backup. The parameters: a: archive mode. Preserve attributes. v: verbose. Not needed for the silent cron version. z: compress during transfer. Not needed if creating a first copy locally but useful for network xfer. x: one filesystem: don't cross file-system boundaries. r: recursive. m: prune empty directories. Essential. progress: live feedback. Not needed for silent cron version. include: files to include exclude: files to exclude. This is required even though we used an include command. *.* is essential. Make neater using variables:

hour=`date +%H`
i="ipynb"
rsync -vrmxz --progress --include="*.$i" --include='*/' 
  --exclude='*' /home/me /mnt/J/backup/hour$hour/

Regarding ddrescue solutions, watch for squashfs: it will create a compressed backup image that can be mounted. Seems better than ddrescue piped to gzip or so.
