No Stupid Questions@lemmy.world•Can you open up an unmanned store in the US and will it stay in business or close down?
251·24 days agoIn many ways a vending machine is precisely that.
AI generated SPAM is beginning to leak through. It’s getting pretty personalised and harder to distinguish from real email.
What does the future of this look like?

Selfhosted@lemmy.world•Why use Proxmox over Podman or Docker?English
7·26 days agoI moved from VMware Fusion after a hardware failure and migrated to Proxmox. I use VMs to isolate client information and to test and use different OS versions and distros.
I have a VM that runs Docker and connect to it via SSH for running applications I don’t want to install on my main workstation.
My main workstation is also a VM.
I came from bare metal Linux for years and found that I spent too much time recompiling kernels to make it work with my hardware.
Now that everything is a VM, changing underlying hardware, and even hypervisor is trivial.
If VMware hadn’t been bought by Broadcom and allowed me to virtualise x86 on Apple Silicon, I’d still be running VMware Fusion. UTM by the way is completely unreliable … I really tried.
As it is, I’m running Proxmox on AMD.
in summary, Proxmox allows me to build what I need when I need it virtually and it’s running on a standard Debian host.
Edit: #$#__# autocorrect (unreadable -> unreliable)

Amateur Radio@lemmy.radio•SDR Enthusiasts - GitHub repositories
3·1 month agoIt’s a collection of repos for different aspects of using SDR to decode, collate and distribute to all manner of different projects.
There’s plenty of documentation and a set of wikis.
Essentially it’s like walking into your nearest hardware store with the instructions to “build a house” … some assembly required.

Yeah, I suppose you’re right, we do like to name things in an understated elegance.

Selfhosted@lemmy.world•How do you manage PHP edits across application upgrades?English
8·1 month agoPHP is written in text files which can be managed using any number of version control systems. Pick your poison.
https://en.wikipedia.org/wiki/List_of_version-control_software
As someone else said, you can document your patches with a Docker file, but you’ll still need to track your changes.
Ultimately, what you’re essentially doing is maintaining a local fork of the code and keeping it synchronised with upstream.

12·1 month agoOn September 11, 2001, nineteen terrorists who were members of al-Qaeda, an Islamist extremist network, hijacked four California-bound commercial airplanes shortly after their departures from airports in Boston, Massachusetts; Newark, New Jersey; and Washington, D.C. In a coordinated attack that transformed the planes into weapons, the hijackers intentionally flew two of the planes into the Twin Towers of the World Trade Center, and another into the Pentagon in Arlington, Virginia. Learning about the other hijackings through telephone calls, passengers and crew members on the fourth plane launched a counterattack. When the passengers attempted to breach the cockpit, the hijacker pilot, who had changed course toward the nation’s capital, crashed the plane into a field in Somerset County, Pennsylvania, near the town of Shanksville.
Nearly 3,000 people were killed on that day, the single largest loss of life resulting from a foreign attack on American soil, and the greatest single loss of rescue personnel in American history. Approximately two billion people, almost one third of the world’s population, are estimated to have witnessed these horrific events directly or via television, radio, and Internet broadcasts that day.

1·1 month agoWhat are you trying to block?
I’m asking because based on the traffic I saw on a live retail website had malicious access attempts coming from significantly more addresses than you seem to be indicating and more often than not the address was different for each request.
That said, Meta DDoS bots were outright blocked because they hit the same URL thousands of times for no apparent reason.
Note that this was during the first half of this year, the landscape has undoubtedly worsened since then.

Selfhosted@lemmy.world•What is your cloud backup solution?English
1·2 months agoFor how much data?











Since radio spectrum is shared globally because radio waves don’t follow political boundaries, it’s coordinated by a UN body called the ITU, the International Telecommunications Union.
There are a few frequency ranges set aside for so-called ISM (Industrial Science and Medical) use.
The 2.4 GHz band was set aside for such use and together with Wifi, Bluetooth and baby monitors, it’s used for all manner of other things.
Since the range at low power is quite short, many devices can share the same frequency and not interfere with each other.
Here’s some background.
