Ftrace is working now on my loongson box

http://www.linux-mips.org/archives/linux-mips/2009-04/msg00112.html

So I confirmed that this MIPS ftrace support is really working. Thanks to Wu Zhangjin (吴章金). However, I have no interest in finding out what kind of difference between my loongson2f patch and wu's caused wu's ftrace patch does not work on top of my loongson 2f patch. What I would like to see now is to get loongson2f patch merged into mainline.

Plus, I wish I could make loongson linux to be able to use 4k page(Now, loongson could only use 16k page in order to avoid d-cache aliasing). I have already started working on it now. Even if it turns out that I can't, I could tell others what I have done in order to achieve this goal. And by that time, I would've got a much deeper understanding of Linux's memory management subsystem.

Send $SGB (Songbird) to another wallet using a script

You need nodejs and web3 to run it:  const Web3 = require('web3'); // Variables definition const privKey = '8xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx2'; // Genesis private key const addressFrom = '0xAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA'; const addressTo = '0xBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBB'; const web3 = new Web3('https://songbird.towolabs.com/rpc'); // Create transaction const deploy = async () => { console.log( `Attempting to make transaction from ${addressFrom} to ${addressTo}` ); const createTransaction = await web3.eth.accounts.signTransaction( { from: addressFrom, to: addressTo, value: web3.utils.toWei('1', 'ether'), // Send 1 SGB. 'ether' is not a typo here. gasPrice: web3.utils.toWei('225', 'Gwei'), gas: '21000', }, privKey ); // Deploy transaction const createR

Rippled thread cpu usage

Image
The cpu usage of xrp.ninja validator spikes every 2 hours. I always wonder what it is doing during the spikes. So I wrote a script to report the thead cpu usage to a statsd server.  I started statsd/graphite/grafana using  https://github.com/ripple/rippledmon Then I wrote this script: #!/usr/bin/python3 import collections import itertools import os import re import statsd import subprocess import time HEADER = b'%CPU COMMAND' STATSD = 'XXX' PORT = 'YYY' PREFIX = 'rippled.threads' TOP = 'env HOME={0} top -b -n 1 -p $(pgrep rippled) -H'.format(os.getcwd()) def report(c, jobs): p = subprocess.run(TOP, shell=True, stdout=subprocess.PIPE, stderr=subprocess.PIPE) if p.returncode != 0: print(p.stderr) return m = collections.defaultdict(float) for line in itertools.dropwhile(lambda x: x != HEADER, p.stdout.splitlines()): if line == HEADER: continue usage, comm = line.decode().str
