1. Clone, sh get_deps.sh, and make run https://github.com/lantiga/RedisTF
2. pip install redis tensorflow
3. cd models
4. Run python tf-minimal.py to prepare a minimal graph
5. The attached redistf-py.py demonstrates how to run the test in the README from Python:

$ python redistf-py.py
Setting the graph: OK
Setting tensor t1: OK

Edgexfoundry and Redis for Core Data PoC

Objectives

• Implement the Redis client for edgex-go core data client tests/benchmarks
• Compare between TCP, UDS and embedded Redis connections vs. Mongo's

Setting up

Server set up

itamarhaber

Reading Building a sliding window rate limiter with Redis, and w/o addressing the actual logic (which may or may not work).

Optimize by:

1. Lua seems a much better choice: idiompotent, portable, server-side, less bandwidth, atomic...
2. The call to ZRANGEBYSCORE seems to be unused, should be commented out if so
3. Looking at the use of ZRANGE, it appears that ZCARD it what's actually needed

The (untested) Lua snippet:

             local 
            h,d,r=9,
           0,{} while
          h>0 do local
         l='' h=h-1 for
        x=0, 38 do local
       a=x-6 if a<0 then a
     = -a end if a <= d then
    l = l .. '*' elseif (0.3/
   (h+1)) > math.random() then

--[[
Sets a bitmap range

Bitmaps are stored as Strings in Redis. A range spans one or more bytes,
so we can call `SETRANGE` when entire bytes need to be set instead of flipping
individual bits. Also, to avoid multiple internal memory allocations in
Redis, we traverse in reverse.

Expected input:
  KEYS[1] - bitfield key

Subject: Organizational challenges

Hi, As CDO of this company, it is my job to also to organizate because that's what the big-O in my title is for. Right?

I don't know everything about anything or nothing, but I feel compelled to do my job and clearly organilizing - my expertise after all - is the solution. Since I have the class' attention now I guess I'll need to improvise so:

This is my friend
His name is ZADD
He's is a lad
Who's always SADD


It's really bad
That ZADD is SADD
I don't know why
And that makes me SCARD
