Netflix Titus

Netflix has open source Titus, container management platform that handles thousands of EC2 instances in AWS for movie streaming..

Based on Apache Mesos, handles half million containers deployments and 200,000 clusters per day leading to three million container launches per week!.

Powerful implementation indeed!.


Azure IoT MCU Chip

Microsoft launched a new MCU that offers device connectivity to Azure platform with builtin security to offer a secure pipe for control and data communication..


Microsoft has fully embraced Unix with a variant as Kernel and calls it Azure Sphere OS!.

Produced by MediaTek, it is a  single-core ARM-A7 running at 500MHz with Wi-Fi and other I/O connectivity options..

Amazon had a similar OS launch last year, It is OS alone with capability to run it on any chip that can be embedded into devices. Microsoft has gone one step further to test it with a particular chip also.

Who’s Next?

AI on a chip..

Seems to be getting some focus lately. Nvidia’s Volta, ARM’s Trillium, Intel with Nervana, Microsoft with Catapult and Google with TPU are the starting points for the silicon AI.

With comparisons to 80387, GPUs the AI in silicon seems to be suited for getting high speed analytics into edge devices if dedicated chips can help in reducing device footprint rather than using general purpose CPUs.


Dropbox saving with onpremise infra

Dropbox moved out of the AWS and went in reverse direction two years ago. Saw a news item explaining the savings that they had with moving to onpremise infrastructure.

Begs the question : What is the saving we get moving to cloud?.

What is cheaper : Compute, Storage, better security, maintenance, technology refresh, technical resources to manage infra?.

Any thoughts?

SMSC number update

Have a OnePlus 2 phone with BSNL number and international roaming enabled. Once I get back to India the Outgoing SMS will not work, reason SMSC number is lost in SIM. Had been struggling to set this everytime, here is the steps that makes it work:

  1. Put the BSNL SIM in slot 1 (inner one)
  2. Dial *#*#4636#*#* from the Dialer application (This doesn’t work from any other phone application, use only the native phone application)
  3. This will bring up “Testing” menu
  4. Goto Phone information
  5. Scroll down, you will see SMSC with UPDATE and REFRESH buttons
  6. Press REFRESH, if it gives error do the following
  7. Enter (with the double quotes included in beginning and end) “+919440099997”
  8. Press UPDATE, it will not give any response back
  9. Press REFRESH, it should show “+919440099997”,145
  10. You are all set to send out SMS.

This should be same for the other OnePlus models also. Alternate way of dialing **5005*7622*+919440099997# was giving connection not available or invalid IMI code.
