Setting up GitHub Pages

GitHub allows you to host pages directly from your repo Here are the steps I did: For GitHub:

• Create a repository for your project (you can name it anything).
• Add your HTML file (e.g., index.html) to the repository.
• Go to the repository’s Settings > Pages.
• In the Source section, select the branch where your HTML file is located, and choose the root folder.
• GitHub will provide you with a link to access your hosted HTML page.

Fedora Server on Minix NEO Z64W

The Minix NEO Z64-W is intended to run Windows, but, since it has an Intel chipset, it runs Linux Server pretty well. Until a few days ago, I had a stable version of Ubuntu Server 20 LTS running there. A failed attempt to upgrade to Ubuntu LTS 22 brings me here.

Moving from Android to iPhone

Calling AWS Lambda functions from LINQPad

• Open LINQPad
• Add reference to JSON.NET
• Use this C# statement to call a Lambda function in AWS:

 var lambdaUrl = "https://<base>.amazonaws.com/default/<api>";

var message = "some message";
var data = new { message };
var payloadJson = JsonConvert.SerializeObject(data);

var client = new HttpClient();
var request = new HttpRequestMessage(HttpMethod.Post, lambdaUrl);
request.Content = new StringContent(payloadJson, Encoding.UTF8, "application/json");
var response = await client.SendAsync(request);

Console.WriteLine(await response.Content.ReadAsStringAsync());

In order to create/configure the lambda function, follow these steps:

• Login to AWS
• Search for Lambda
• Create new function
  • Select existing permission lambda_execution
• Go to Configuration
  • Create New trigger of type API Gateway
  • Set Security to None

Fix apt upgrade error when connecting to fr.archive.ubuntu.com

Recently, when trying to upgrade my tiny Ubuntu Server, got this error:

Failed to fetch http://fr.archive.ubuntu.com/ubuntu/dists/focal-updates/InRelease  Cannot initiate the connection to fr.archive.ubuntu.com:80 (2001:bc8:1600:4:63f:72ff:feaf:a2de). - connect (101: Network is unreachable)

I thought that the issue was related to IPv6, so I disabled it:

nano /etc/sysctl.conf1

Add:

net.ipv6.conf.all.disable_ipv6 = 1
net.ipv6.conf.default.disable_ipv6 = 1
net.ipv6.conf.lo.disable_ipv6 = 1

Run sysctl -p

Confirm cat /proc/sys/net/ipv6/conf/all/disable_ipv6 It should return 1 (disabled)

This didn’t help (also got error with IPv4)

W: Failed to fetch http://fr.archive.ubuntu.com/ubuntu/dists/focal/InRelease  Could not connect to fr.archive.ubuntu.com:80 (51.158.154.169), connection timed out

So, after doing a ping to fr.archive.ubuntu.com and confirming it’s down, just replaced it with us.archive.ubuntu.com:

nano /etc/apt/sources.list

Finally packages upgrade is running

apt-get update
apt upgrade

A few things missing

2. If you customized the Downloads folder, it does not persist when saved from the UI Open the config file /home/qbittorrent-nox/.config/qBittorrent/qBittorrent.conf and save it the [Preferences] section ` Downloads\SavePath=/media/torrents/ `
3. Restart the service for the changes to take place systemctl restart qbittorrent-nox

How this site was created

Publishing a site using an SSG from GitHub Actions

After using Wordpress for several years (on-off), I decided to move to SSG (Static Site Generator) I come to love markdown, and the ability to write my posts from VS Code directly.

So, here I will just give a high level overwiew of what takes to create a simple site using SSG.

Home Server with Ubuntu and a Streaming Device

Installing Ubuntu and Tranmission in a Minix Neo Z64-W

Got a Minix Neo Z64-W from a friend, it comes with Windows, and runs pretty sluggish My old XtreamerTV device managed to burn two internal 2.5” hard drives (this is another story) So, project at hand:

• Install Ubuntu Server on the Minix Neo Z64-W
• Configure a few critical services:
  • SSH
  • Samba (to access content in the local network, upnp is better, but VLC cannot get subtitles using upnp)
  • duf (just because)
• Mount external USB disk, and make sure it’s mounted after restart
• Install Transmission
