Re: Please remove broken mirror from mirrordirector

It would be much nicer if the mirror director tried the next mirror if it did not work The mirror director just looks up the requested file and the clients location in a database and returns a redirect. There is a mechanism in place to disable broken mirrors but it only works if the mirror is broke...

Re: mirrors.opencas.cn mirror can not be reached

The problem is the mirror is IPv6 only but the mirror redirection system wasn't aware of that fact. So it was sending ipv4 clients to it.

I have updated the settings in the mirror redirection system so ipv4 clients should no longer be sent to that mirror.

Re: Please remove broken mirror from mirrordirector

Thanks for the information.

I have confirmed that the mirror does not have an ipv4 address and have reconfigured the mirror redirection system so that only ipv6 clients will be sent to that mirror.

Does this solve your problems?

Re: Package availability libell

libell0 and libell-dev are in Raspbian buster, they are not in Raspbian stretch. This seems to line up with the situation in Debian.

Re: Offline Repository

rsync will grab the whole repository.

If you just want a subset of versions or architectures from a repository there is a tool called debmirror that can do it. This can also be used to mirror repositories that are only available over http (like the raspberry pi foundation respository)

Re: Wolfram on Raspberry Pi Desktop for PC

Basically wolfram is normally a very expensive piece of software.

Giving it away on the Pi gets people into their platform without really affecting their main market because the Pi is a pretty weak computer. Giving it away for Linux on the PC would be far more likely to impact their main market.

beditd, a binary file editor inspired by DOS edit.

modulo7 and I have been working on a binary file editor inspired by the binary mode in dos edit. This is not a hex editor, it operates more like a text editor, with each byte value being represented by a different symbol on the screen. It runs in a utf-8 terminal.

Re: SWI Kernel Calls broke?

Historically on arm operating systems, the parameter of the SWI instruction was used to select the system call. This was however problematic in a couple of ways. 1.

Re: Help:Why my Raspberry Pi‘s 5v power port output 7.5-8V?

That other thread you link is getting a high reading on the 3.3V but a normal reading on the 5V. Here all the readings are high in about the same ratio which suggests a meter whose voltage reference is too low either because the meter is faulty or because the battery is low.

Re: Help:Why my Raspberry Pi‘s 5v power port output 7.5-8V?

if the Pi is otherwise working it is highly unlikely that those voltage readings are real.

i strongly suspect there is something wrong with your multimeter, perhaps a low battery.
