Gasoline and diesel vehicles produce a large sum of poisonous emissions from the tailpipe. Vehicles are confined in a small space as with the tunnels being built by Elon Musk’s “The Boring Company”, the amount of ventilation required to keep the air breathable would be a huge cost burden to the construction of small tunnels (think of the large ventilators at the top of current tunnel systems)
It seems, although The Dash sports “dual pulse oximeter sensors”, it currently is only capable of measuring heart rate with these sensors. Bragi has informed me that, although blood oxygen measurement is possible, it is not a high priority on the roadmap at this time:
From the hardware perspective, it is definitely possible to measure blood oxygen saturation. This was also communicated as a long-term goal when having designed The Dash. However, the operating system has many different conditions that need to be held when wanting to implement this feature. Therefore, Bragi OS still needs to be developed so that measuring further body vitals is possible. I hope it is understandable that our developers were not able to implement those features, yet.
Set better keyboard repeat rates with the following commands in terminal. Before running the commands set your Key Repeat and Delay Until Repeat to the fastest options (System Preferences->Keyboard).
#disable special characters when holding keys
defaults write NSGlobalDomain ApplePressAndHoldEnabled -bool false
# normal minimum is 15 (225 ms)
defaults write -g InitialKeyRepeat -float 10.0
defaults write NSGlobalDomain InitialKeyRepeat -float 10.0
# normal minimum is 2 (30 ms)
defaults write NSGlobalDomain KeyRepeat -float 1.0
defaults write -g KeyRepeat -float 1.0
Log out and back in and your keys will be blazing fast. Don’t set them too low or you will have trouble using your keyboard to type in your password (trust me, I tried super low values and almost got locked out). If you re-open or adjust your keyboard settings from the system preferences menu, you may have to re-run these commands (so keep this post handy!)
Give yourself a fresh mac address.
- Generate a random valid MAC:
openssl rand -hex 6 | sed 's/\(..\)/\1:/g; s/.$//'
- Set it:
sudo ifconfig en0 ether 00:00:00:00:00:00
Obviously you’ll need to replace 00:00:00:00:00:00 with your generated mac address. Don’t mind the openssl error “unable to write ‘random state'”. It worked just fine.

Basic help runtime details from https://github.com/ethereum-mining/ethminer
Example to mine with Nvida CUDA enabled: ethminer.exe -RH -U
Usage ethminer [OPTIONS]
Work farming mode:
-F,--farm Put into mining farm mode with the work server at URL (default: http://127.0.0.1:8545)
-FF,-FO, --farm-failover, --stratum-failover Failover getwork/stratum URL (default: disabled)
--farm-retries Number of retries until switch to failover (default: 3)
-S, --stratum Put into stratum mode with the stratum server at host:port
-SF, --stratum-failover Failover stratum server at host:port
-O, --userpass Stratum login credentials
-FO, --failover-userpass Failover stratum login credentials (optional, will use normal credentials when omitted)
--work-timeout reconnect/failover after n seconds of working on the same (stratum) job. Defaults to 180. Don't set lower than max. avg. block time
-SC, --stratum-client Stratum client version. Defaults to 1 (async client). Use 2 to use the new synchronous client.
-SP, --stratum-protocol Choose which stratum protocol to use:
0: official stratum spec: ethpool, ethermine, coinotron, mph, nanopool (default)
1: eth-proxy compatible: dwarfpool, f2pool, nanopool (required for hashrate reporting to work with nanopool)
2: EthereumStratum/1.0.0: nicehash
-RH, --report-hashrate Report current hashrate to pool (please only enable on pools supporting this)
-HWMON Displays gpu temp and fan percent.
Email address used in eth-proxy (optional)
--farm-recheck Leave n ms between checks for changed work (default: 500). When using stratum, use a high value (i.e. 2000) to get more stable hashrate output
-M ,--benchmark  Benchmark for mining and exit; Optionally specify block number to benchmark against specific DAG.
--benchmark-warmup Set the duration of warmup for the benchmark tests (default: 3).
--benchmark-trial Set the duration for each trial for the benchmark tests (default: 3).
--benchmark-trials Set the number of benchmark trials to run (default: 5).
-Z ,--simulation  Mining test mode. Used to validate kernel optimizations. Optionally specify block number.
-G,--opencl When mining use the GPU via OpenCL.
-U,--cuda When mining use the GPU via CUDA.
-X,--cuda-opencl Use OpenCL + CUDA in a system with mixed AMD/Nvidia cards. May require setting --opencl-platform 1
--opencl-platform When mining using -G/--opencl use OpenCL platform n (default: 0).
--opencl-device When mining using -G/--opencl use OpenCL device n (default: 0).
--opencl-devices <0 1 ..n> Select which OpenCL devices to mine on. Default is to use all
-t, --mining-threads Limit number of CPU/GPU miners to n (default: use everything available on selected platform)
--list-devices List the detected OpenCL/CUDA devices and exit. Should be combined with -G or -U flag
-L, --dag-load-mode DAG generation mode.

Even with the 50% discounted preemptable instances now available in Google cloud, cryptocurrency (BTC, LTC, ETH, XMR, other) mining is simply not profitable.
Despite the shady steemit article “Ethereum Mining with Google Cloud (Nvidia Tesla K80) actually works and is highly profitable”, no,
Mining on these GPUs is simply not a profitable business.
BCN mining on the K80 is about 126 H/s per GPU. ($12/month at the current price/difficulty)
ETH mining on the K80 is about 6.5Mh/s (CUDA Mining)
ETH mining on the K80 is about 7.1Mh/s (OpenGL Mining)
ETH / Sia coin mines roughly 7.1 and 71.8 MH/s (respectively, via Claymore Dual Eth Miner)
