Yeah, but I don't really want to spend any money. I know that things like this exist because there is USB over IP , but I can't get it to work.
Sell the Pi and buy hub with the money. Or make exchange with someone.

Have you tried this sdtool:

Re: Protecting Proprietary software from being copied.

Small executable runs from SD card. Loads another encrypted executable in memory. Decryption is made with S/N of SD card and then the main executable is started. If you clone the SD card, the soft will not run because S/N of the second card is different.

Re: Protecting Proprietary software from being copied.

The question for software protection is very old and discussed million times without ultimate solution. Using hardware dongle is one of the "strong" methods, but there are at least 2 problems: 1) The price of dongle is not small and for cheap software it is useless. E.g. if you want to sell software...

The title is "no longer readable on windows" - sd formatter is necessary to become readable on Windows.

Hibernation

Is there a chance for implementation of hibernation / restore of Raspbian or reason why it is not possible? The purpose is mostly to speed up boot process, not to save current state.

Some things that would truly surprise me in the Pi4B (though not necessarily so in later models than that)... 4GB RAM. USB3.1 CPU clock greater than 2GHz. SATA connector. Direct SoC Ethernet interface. Lower on the surprise scale (that is, surprising but not causing "where did *that* come from" whi...

Re: Where to buy WD PiDrive

From early announcements about PiDrive I have the impression that HDD has lower power consumption than standard 2.5" hdd and single USB 2.0 port is enough as power source. But now I see Y-type cables and probably are necessary 2 USB ports. If this is true, then the only advantage of PiDrive is the i...

Where to buy WD PiDrive

Hi. I tried to find PiDrive without Node Zero but it seems sold out. Is it available somewhere (at normal price)? Or if I get enclosure for external HDD and put SSD inside - will it work with the power supply from Pi USB port? I hope the SSD needs less power than 2.5" hdd.

Re: Remote access via website subdomain. How !?

Do you have static IP for each RPi? Most simple and safe method for remote access is SSH and other services like X or MySQL over SSH. If you have static IP, pi01.mydomain.com will be a easy-to-remember name for IP. And centralized info for hypothetical hackers to find all your Pi-s :)

Probably Mono can run under RPi. Then C# is good choice - much better than Python and similar.

Re: So Many Languages, so little Time

That would be why a RAD tool/language is useful. Pay for a little speed loss over C but compiling is much faster. Faster compile = faster code/compile/test cycles. Not as bad as the old days of going out for lunch while the compiler crunches C code. RAD tools are not for fast compiler but for fast ...
