Trying out old Macbook Pro laptop that I got for cheap.
Barrier is the open source successor of Synergy.
How to reset OS X laptop:
- Old style(s): https://apple.stackexchange.com/questions/363738/os-x-snow-leopard-wont-boot-into-recovery-mode-need-to-reset-admin-password/363745#363745
- Cmd line magic that resets users
- Download snow leopard from archive.org
- New style, I think CMD + R at startup.
Need YUMI UEFI. Then install a 32-bit linux.
- Need to adjust the kernel boot options in the grub.cfg in the drive. Append nomodeset to the "nofloppy" on the line that boots the iso. Trying ubuntu for now, but their support for 32-bit is too old. Now for debian
Need to start /snap/bin/barrier
- Compile latest openssl: http://techscienceinterest.blogspot.com/2010/12/compiling-openssl-on-mac-os-x-snow.html
- Latest python that has binary installer is 3.7.4 or something.
Connector is 13mm, with 26 pins with .5mm spacing. QK-AK7 below might have the spacing, but doesn't have the proper width (although maybe can still use larger connector, not sure). And doesn't likely let you re-program the microcontroller to get backlight working? Maybe...
There are more expensive ones too.
But won't have trackpad and still have to make case around it. We'll see long term.

I was listening to Brendan Gregg talk about the future of performance technologies and he didn't have a lot of good stuff to say about Optane / 3D XPoint except it can scale to large storage sizes and might act as a good hard drive cache :) https://youtu.be/5nN1wjA_S30?t=1090
So, to defend that:
- Cost: PMem needs to meet or beat DDR/Flash on price/(performance or size) to get large adoption. Not sure if it's there or not.
- It won't beat DDR on latency and bandwidth, true. However, DDR loses info on loss of power. Some companies will opt for a battery / supercapacitor / diesel generator and finish the cache flush, not sure how much that costs (apparently high enough to not require it for all NVDIMM platforms https://www.usenix.org/system/files/login/articles/login_summer17_07_rudoff.pdf), but it's a higher performance option. Others might opt for Optane, with enough comparable speed and persistence, but more annoying flush issues.
- Close to DRAM performance at a higher density at a cheaper price point
At the end of the day, you don't know as a company if it will work out! You need large groups of people to risk a lot of money wisely to determine if it's worth doing! Otherwise, it won't get invented/done!
Inserting pages is kind of ok with Linux tools (pdf shuffler). But requires you to have it in PDF format already.
The Mac Preview tool is very easy to use. However, do I want to keep around an older Mac laptop just for that?
