IVARcluster, prices in SGD at time of commit.

To make it more interesting, this setup should include a variety of motherboards, SSDs, HDDs, memory and PSUs. I might start with one system, and build another one every 6 months. I forsee this list changing over time, but the base specifications are as follows:

  • CPU: >6 core, >4GHz
  • Storage: >256GB NVMe
  • Memory: >16GB, dual channel

serverwentdown / extra_tabs.tmpl
Last active August 2, 2019 15:49
A custom template for Gitea to embed pages into tabs with an iframe. Requires the proper X-Frame-Options and Content-Security-Policy on the linked resource. The example below is how I use it for Drone. Install into data/gitea/templates/custom/extra_tabs.tmpl as described on https://docs.gitea.io/en-us/customizing-gitea/#customizing-gitea-pages
<a class="item" href="https://your.domain.here{{.RepoLink}}" data-iframe-tab="builds" title="Builds">
<i class="octicon octicon-gear"></i> <img src="https://your.domain.here/api/badges{{.RepoLink}}/status.svg?ref=refs/heads/master" style="width: auto">
</a>
<script>
document.addEventListener('DOMContentLoaded', () => {
const openFrame = (tab) => {
const name = tab.dataset.iframeTab;
const page = tab.href;
