I’ve improved my home tv app to watch local media files such as movie, picture, and audio. in addition to live TV. I uses HLS and hardware encoding to achive this function. Thanks to Nvidia, I can see any media files on the fly!
Also, I improved EPG capability to see coming programs.
There is some minor subject to improve, but I can enjoy my local media from everywhere!
My home tv has already been able to see via ip network, and I’ve updated to be seen on smartphone.
The work was completed in 2 days. The total working time is about 10 hours. I’ve satisfied with result, and I can see my home TV in anywhere!
Huge aquarium! Whale shark is cute!
Nice and cozy family-run Ryokan, hot springs, and cuisine. Relax so much with kotatsu!
Nice famous breakfast and kaiseki lunch.
I’m so lucky that Kiyomizu-dera is not crowded because of COVID. Beautiful late autumn landscape!
Kanazawa is small but elegant city and more modernized than Kyoto, I think. It seems that Kanazawa has already ready for winter season. Nice teppan-yaki cuisine!
city with retro, plenty of clear water, and nice food. kumamon!
good old city and landscape.
Gotenba Premium Outlet is inconvenient to access from Hakone and no guide is provided. But using bus, it takes reasonable time to get there.
My home’s internet has already upgraded to 1Gbps from 100Mbps a few months ago, but I had used old Raspberry Pi 3 box for my internet router. So it achived only 5-10 Mbps as download bandwidth.
I have old NUC box for TV, but seemed slow a little bit. So I’ve reused it for internet router.
As a result, I’ve achived 500Mbps as download bandwidth. It’s x100 performance improvement !
I think that it’s worth for reuse oridinary pc for another use for enhance product life and saves unneccesary costs!
Not so hot and not so cold. Beautiful autumn leaves. Nice for my eyes and tongue, but forgot to take pic of leaves ;-)
emergency escape from melting pot…!

Thanks to my ZFS, I’ve kept all of my data healthy despite of massive error rate. And I’ve moved all of my data to new HDD and chassis.
Here is my old NAS box. This is HP Microserver gen 1 wokred with NAS4Free for almost 10 years. I had experienced no failure on the box and hdd itself. Also it achives about 50W power consumption. This is amazing result.
I’ve replaced old Seagate ST8000AS0002 archive HDD to Western Digital WD82PURZ. This two types of HDD has almost same size, 8TB. I continue to use NAS4Free and ZFS, but add more memory to work cache more efficiently. Here is spec.

Due to change HDD’s rotation speed from 5,400 to 7,200, my experience is highly improved.
My home farm gets fat over last 5 years and heavily depends on kvm virtualization. Here is diagram. There is too many physical boxes. I tried to consolidate some box and seeks alternative solution for reduction of power consumption.
I think that using Raspberry Pi for general purpose computing such as network router, mail server, dns server, and so on is nice idea. I’ve moved router, mail server into Raspberry Pi.
Also consolidated encode server with one of desktop. Written above, I’ve retired old nas box and moved into kvm box. Here is my current configuration diagram.
As a result, I’ve wiped 1 phisycal box, 1 physical box replaced with RPi box, and all of virtualized (and complex) environment. Along with these effort, I’ve achived about 25% energy efficiency improvement.
Old config estimated power consumption: 600W
Current config estimated power consumption: 450W
worth to revisit ! Saza coffee is great.
mashed up!
Hello, again !
looking for Spring. Max 300 km is enough for me.
