Doing a manual upgrade of my Ceph cluster. In the same process, I get the Debian operating system upgraded that my Ceph cluster is running on. The new version of Ceph called Pacific requires some extra measures and when you've updated you can't go back.
We talk about the struggles I had with running inferences in Java using a Keras model in tensorflow. This is the train.py used in this example. import tensorflow as tf #import tensorflowjs as tfjs import os from datetime import datetime from tensorflow.keras.models import Sequential, Model from tensorflow.keras.layers import Conv2D, MaxPooling2D, BatchNormalization, Layer from tensorflow.keras.layers import…
We talk about the different collection structures in Java and how to measure their performance and memory footprint Simple example of performance testing for collection types in java: package org.ea.debugger; import java.lang.management.ManagementFactory; import java.util.*; import java.util.function.IntConsumer; public class CollectionTest { public static void sleep() { try { Thread.sleep(3000); } catch (Exception e) { e.printStackTrace(); }…
Going though the process of solving the advent of code challenges for this year.
What can you learn from examining code in multiple languages?
We look at the new features in the Ceph Quincy release. Talk about changes and important improvements. Looking forward to starting using this on my clusters.
I’m trying to solve all the Advent of Code puzzles in this video series.
