Today I received an invite for the OnePlus X. The code is: GL71-90E4-75E1-DBA7. This invite is valid for 3 days.
One has to edit
/etc/nginx/nginx.conf and add in
client_max_body_size 15900M ;
; Maximum allowed size for uploaded files. ; http://php.net/upload-max-filesize upload_max_filesize = 15900M ; Maximum amount of memory a script may consume (128MB) ; http://php.net/memory-limit memory_limit = 6900M ; Maximum size of POST data that PHP will accept. ; Its value may be 0 to disable the limit. It is ignored if POST data reading ; is disabled through enable_post_data_reading. ; http://php.net/post-max-size post_max_size = 25900M
/etc/php/php.ini I had to stop
systemctl stop nginx systemctl stop php-fpm
so the changes take effect.
After starting the two services then check with
Below is a short overview of small scale computers for use in embedded computing.
- Intel Galileo, single core Quark/Pentium, ca. 100 USD, <15 W
- Intel Edison, dual core Atom Silvermont, 500 MHz, ca. 100 USD, <1 W
- Raspberry Pi, single core ARM, 700 MHz, ca. 35 USD, ~1 W
- Arduino series, e.g., Intel Quark/Cortex, 32 MHz, ca. 15 USD, ~1 W
- ESP8266 (spec), single core Tensilica Xtensa LX106, 80 MHz, 7 USD, 1 mW
On the other end of the spectrum there are Mini PCs.
- Intel NUC, quadcore Intel i5/i7, ca. 400 USD (no SSD+no RAM), 6-60 W
- Apple Mac Mini, Intel i5/i7, ca. 500 USD, 6-85 W
- Apple Mac Pro, Intel 3.5 GHz 6-Core Intel Xeon E5, ca. 4,000 USD, <450 W
Now comes the fun part: connecting many small scale computers to a cluster.
Connecting 64 Raspberry Pi running MPI and putting them all into a Lego frame, see Raspberry Pi at Southampton.
Clustering 48 PandaBoards and putting this all into an industrial trashcan, see Phoronix: Building A 96-Core Ubuntu ARM Solar-Powered Cluster.
Clustering ten Intel NUCs each with 10GB RAM: Orange Box, see The Orange Box: Cloud for the Free Man, motto: Most planes fly in clouds…this cloud flies in planes!
Mac Pros are offered in the cloud, see Dedicated Mac Pro server hosting.
