Hath the blockchain euphoria finally died a quiet death?

I’ve been saying this to 1. customers, 2. tech friends, 3. lesser tech friends, 4. non-tech friends. Not one believed me apart from the Vandy tech gang (where the real tech people are).

Hope the SG govt didn’t throw in good tax payers $ into this slow database.

PINEBOOK Pro

Extremely happy to hear the PINEBOOK is now available in a Pro version. The form factor looks identical to a ThinkPad Carbon (afaics)

There will be support for Linux, *BSD and Android 9. The preorder starts on 25th July 2019 but only for those who had registered in the Pinebook forum prior to 1st July 2019.

I say PINEBOOK had stolen the thunder from Apple on innovation for developers!

Stupendifying! Proptech startup secures $1.47m to improve how agents earn commissions

Started to look through e27 and techinasia and found this ditty on PropTech. This caught my eye as I was exploring some ideas on buying and selling Singapore property six months ago.

Lets see what techinasia wrote.

“Proptech startup secures $1.47m to improve how agents earn commissions

UrbanAgents, an AI-powered platform that links up home sellers to real estate agents, raised about US$1.47 million in seed investment from FarSight Capital, APAC Realty, and angel investors.”

The target audience are real estate agents… Hmm… Right, I’m sure the home buyer and seller will be very pleased to pay more commission out of their own pockets.

I say good luck to FarSight Capital, APAC Realty and angel investors, and tough luck to all these VCs’ backers.

MacBook Pro running hot on Linux?

Managed to get Linux dual booting on an old but high spec’ed MacBook Pro using rEFInd. This was the second time I had Linux on the same machine and i’m still puzzled why the laptop runs cool to touch in macOS but quite warm in Linux.

I had disabled the discrete AMD Radeon GPU which caused display problems in macOS, via nvram.

$ nvram fa4ce28d-b62f-4c99-9cc3-6815686e30f9:gpu-power-prefs=%01%00%00%00

I’ve also reloaded AMDRadeonX3000.kext on login via the following:

$ sudo kextload /System/Library/Extensions-off/AMDRadeonX3000.kext

High Sierra boots up perfectly with the laptop running relatively cool.

But this was not the same for Linux…

I’ve loaded lm-sensors which shows Linux regularly hitting 80+ Celsius while laptop fans spun at 2000 rpm (default speed). Something wrong there, don’t you think?

BTW, I’m monitoring the temperature of CPU cores and the fan speed using sensors

$ watch -n 1 sensors

I decided something needs to be done to bring up the internal fan speed – looking around found tlp.

tlp stands for TLP (duh!) and can be found in many distribution’s repositories. I used this to change the radeon power profile and dpm states by changing the states from default to low.

From /etc/default/tlp

RADEON_POWER_PROFILE_ON_AC=low

RADEON_POWER_PROFILE_ON_BAT=low

RADEON_DPM_STATE_ON_AC=low

RADEON_DPM_STATE_ON_BAT=low

RADEON_DPM_PERF_LEVEL_ON_AC=low

RADEON_DPM_PERF_LEVEL_ON_BAT=low

Followed by restarting tlp with

$ sudo systemctl restart tlp.service

No change to the internal fan speed of 2000 rpm. 🙁

After some googling, I loaded macfanctld.

Right off the bat, sensors started to show the correct fan speed. By pushing additional load (multiple Youtube and Vimeo channels) on the laptop, I can hear the fans working harder and sensors is showing higher internal fan speed.

But this still hadn’t brought the temperature of the MacBook Pro to macOS level of temperature. I’ll continue to update this once i find out why and how.
