IIRC, Elite used lookup tables for trigonometric functions on certain target platforms (maybe the NES) because memory wasn’t as much of a constraint as computing performance. It’s a barrel of game compressed into a pint of code.

Sounds like a cryptobro peddling some shitcoin claiming that it’s impossible to get scammed because “code is law” four seconds before the liquidity pool gets drained through a vulnerability in the code.

Oracle sponsors our university to teach their flavour of SQL (Oracle SQL, not MySQL) with their management software rather than any of the competitors, free or otherwise. One of the DBA teachers once told me that there are enough differences between Oracle and other flavours that the knowledge isn’t immediately transferrable, so when students graduate, all they know is Oracle, and they perpetuate the cycle.

This is obviously an unfair anti-competitive practice, but crimes are only illegal if someone enforces the law.

I didn’t do that exactly… but when my boss told me to do overtime during end-of-quarter crunch on a Saturday night shift (Sat 22:00 to Sun 10:00, factory jobs are fun), the next person I spoke to was my family doctor. She put me on a two-week compulsory medical leave with full pay and straight up told me to get a new job. Unfortunately I couldn’t help the company meet their quarterly growth targets. The next time I saw my boss, I handed him my resignation papers.

Sure feels nice to live in a country with real labour laws.

I enjoyed the work itself. It was very autism-friendly. Unfortunately some absolute boneheaded decisions by the middle management wankers during the pandemic resulted in a huge backlog of orders, a shortage of parts, and a constant state of short-staffing.

Do they accept photographs of my money, or will I have to phone them and jingle some coins at the handset?

I mean whatever level of access is required to upload an image. That can be access to the web app (with login), access through WebDAV, or access to the underlying OS or filesystem. If you can put a file on Nextcloud, it is sufficient access.

I forgot to mention that the vulnerability can only be exploited if libraw is also compiled with a particular flag that enables the vulnerable feature. That flag is disabled on base Debian. Docker’s service doesn’t test whether the vulnerability is actually present in the image, only that the package version is listed as affected.

Those vulnerabilities are inherited from the Debian base image. Debian is extremely diligent about fixing high-risk vulnerabilities. A high severity CVE does not automatically mean that you are at severe risk. It’s more an indication of how fucked you can be IF the vulnerability is exploited to its greatest potential.

One of the CVEs affects libraw, which is a library for handling RAW photograph files. If a RAW file contains a particular header, and that header is maliciously constructed in a particular way, extracting an embedded thumbnail can allow the attacker to execute arbitrary code on the server. To make that happen, the attacker must either gain access to a device (e.g. camera) you own, or already have access to the server to upload and process the file, which means that security has already failed.

The Swiss cheese model applies to cybersecurity too.

I use Docker Compose to run my Nextcloud server using the community image, which in turn lives inside an unprivileged LXC container.

volumes:
  db:

services:
  db:
    image: mariadb:lts
    container_name: mariadb
    restart: always
    command: --transaction-isolation=READ-COMMITTED --log-bin=binlog --binlog-format=ROW
    volumes:
      - db:/var/lib/mysql
    secrets:
      - mysql_root_password
      - mysql_nextcloud_password
    environment:
      - MYSQL_ROOT_PASSWORD_FILE=/run/secrets/mysql_root_password
      - MYSQL_PASSWORD_FILE=/run/secrets/mysql_nextcloud_password
      - MYSQL_DATABASE=nextcloud
      - MYSQL_USER=nextcloud

  nextcloud:
    image: nextcloud:latest
    container_name: nextcloud
    restart: always
    ports:
      - 8080:80
    depends_on:
      - db
    volumes:
      - /var/www/html:/var/www/html
      - /srv/nextcloud:/srv
    environment:
      - MYSQL_PASSWORD_FILE=/run/secrets/mysql_nextcloud_password
      - MYSQL_DATABASE=nextcloud
      - MYSQL_USER=nextcloud
      - MYSQL_HOST=db

secrets:
  mysql_root_password:
    file: ./secrets/mysql_root_password.txt
  mysql_nextcloud_password:
    file: ./secrets/mysql_nextcloud_password.txt

Nextcloud’s file storage is a mount point at /srv/nextcloud, which is backed by a ZRAID pool. The secrets are stored in files with 600 permissions. The web server is initially exposed on port 8080.

When you run the container for the first time, it will show a first time setup dialog. You’ll have to fill it out manually, using mariadb for the database type and db for the database hostname.

If Nextcloud works through HTTP, you can then set up a proxy for HTTPS. I used Nginx running on the same LXC. I can’t guarantee that my config is adequately secure, use it at your own risk.

upstream php-handler {
	server 127.0.0.1:9000;
}

server {
	listen 80;
	listen [::]:80;
	server_name nextcloud.your.domain;
	return 301 https://$host$request_uri;
}

server {
	listen 443 ssl http2;
	listen [::]:443 ssl http2;
	server_name nextcloud.your.domain;
	keepalive_timeout 70;
	client_max_body_size 32G;

	ssl_certificate /etc/nginx/ssl/ssl.crt;
	ssl_certificate_key /etc/nginx/ssl/ssl.key;
	ssl_protocols TLSv1 TLSv1.1 TLSv1.2 TLSv1.3;
	ssl_ciphers HIGH:!aNULL:!MD5;

	add_header Referrer-Policy "no-referrer" always;
	add_header X-Content-Type-Options "nosniff" always;
	add_header X-Download-Options "noopen" always;
	add_header X-Frame-Options "SAMEORIGIN" always;
	add_header X-Permitted-Cross-Domain-Policies "none" always;
	add_header X-Robots-Tag "none" always;
	add_header X-XSS-Protection "1; mode=block" always;

	fastcgi_hide_header X-Powered-By;

	location / {
		proxy_pass http://127.0.0.1:8080/;
	}
}

To allow the web app to work using the DNS name, you’ll have to edit /var/www/html/config/config.php and change/add these values:

'trusted_domains' => array(
    0 => '127.0.0.1:8080',
    1 => 'nextcloud.your.domain',
    // 2 => whatever other addresses you want to use
),
'overwrite.cli.url' => 'https://nextcloud.your.domain/',
'overwriteprotocol' => 'https',
'overwritehost' => 'nextcloud.ng.local'

If at any point you need to start over, remember to delete the contents of /var/www/html.

(edit) Forgot to mention: the web server will accept connections from all addresses, you’ll need to set up a strict firewall to only allow 443 (maybe 80) and 22.

Would love to get some feedback from the self-hosted community

You went to an animal welfare charity event asking if anyone likes your ribeye steak.

Skirt and programming socks. The skirt provides optimal airflow and the socks can be adjusted using a PID algorithm to achieve the desired thermal equilibrium.

Stakeholders. Journalists. The market. The ignorant public. They’re constructing a narrative to shield themselves and minimize the hit to their reputation when they stop offering lifetime license plans. The announcement won’t look nearly as damning if it contains a reference to the falling number of new lifetime customers, even if it omits the context of why that number has been falling.

From a purely profit-oriented perspective, no. They’re setting up a pretext to eliminate the lifetime license plan due to a lack of interest. No sane person would pay that kind of lump sum for the service (and the insane ones will bring in triple the revenue), so they’ll claim that there is no market for it. After that, they’re free to crank up the periodic subscription prices.

Never attribute to stupidity that which is adequately explained by profiteering opportunism.

Open config.php and look for the entry named trusted_domains. Make sure it contains both the domain name and the local IP address:

'trusted_domains' => array(
    0 => 'nextcloud.your.domain',         // the public FQDN
    1 => '172.22.?.?',                    // the local IP address
    2 => '...',                           // other addresses, like if you're using a VPN
),

If the web app is opened using an address or DNS name that isn’t included in this list, the browser will connect, but the app will refuse to work.

Nevermind, I completely overlooked that the service is Opencloud, not Nextcloud. Nevertheless, you should investigate whether Opencloud has an equivalent config variable.

Just install linux bro, it’s not that difficult. You’ll have to compile the F-35 drivers from source, but that’s just the cost of having a reliable system.

Read my comment again, it has the answer. Most VPN services do not provide end-to-end tunnelling. If the exit node is located outside Russia, then what enters the Russian internet will be simple HTTPS traffic.

Been running it from Russia where stock WireGuard stopped working mid-2025.

Sounds like the issue is ISPs within Russia blocking outgoing Wireguard traffic from customers.

If the traffic exits the tunnel without hitting a Russian ISP (e.g. a Mullvad exit node in Sweden that routes the unencrypted traffic to the destination), you won’t be affected. If the exit node is behind a Russian ISP, it might get filtered by DPI depending on which direction is subject to the filter.

It’s problematic, but possible: https://jamesguthrie.ch/blog/multi-tailnet-unlocking-access-to-multiple-tailscale-networks/

If the other person has a Tailscale account, it sounds like the most expedient method is to simply invite them to the tailnet as a non-admin user with strict access control.

You could share a node with an outside user, but I don’t know how much the quarantine would affect its functionality. You could also use Funnel to expose the node to the internet (essentially like a reverse proxy), but there are obvious vital security considerations with that approach.
