#StackBounty: #tikz-pgf #debian #polarplot #tikzlibrary How to draw polar grid system around another grid for object in TikZ 3D?

Bounty: 150

I am trying to put two polar planes/axis around an object (here heart in Fig. 2) by TikZ/… translations and rotations for 3D phenomenon.
I think the problem is to Translate and rotate the second polar grid around the object (heart) for 3D phenomenon.

I can do one polar grid as described in the thread Creating a Polar Grid with Tikz.
You can use Fig. 2 heart directly which needs the polar system around it.
I can rotate objects (here the second coordinate system), described in the thread Translate and rotate an object in TikZ (2D).
The 3D translation can be done as described in the thread answer Tikz:: shift and rotate in 3d?
The 3D rotation seems is without a solution but I am not sure if it is the only limiting factor here.

Fig. 1 Target object,
Fig. 2 Heart in Mathematica (here code),
Fig. 3 Output of the code in 2D plane

#StackBounty: #debian #window-manager #desktop-environment How to install CDE on Debian?

Bounty: 100

According to Wikipedia, the Common Desktop Environment was released under the GPL and at one time was ported to Debian. But searching through Debian’s software repository, I was unable to find CDE. Is there a simple way to install CDE on Debian 8?

#StackBounty: #networking #debian #wireless-access-point Automatically enable new networks

Bounty: 50

Using a stripped down debian (jessie) on a headless server (Dockstar, Armel). I had previously plugged in a MiFi (WiFi access point) with USB tether, and the Dockstar found it:

Mifi USB tether
usb 1-1.4: new high-speed USB device number 6 using orion-ehci
usb 1-1.4: New USB device found, idVendor=1410, idProduct=b00c
usb 1-1.4: New USB device strings: Mfr=1, Product=2, SerialNumber=3
usb 1-1.4: Product: MiFi 6620L
usb 1-1.4: Manufacturer: Novatel Wireless
usb 1-1.4: SerialNumber: 0123456789ABCDEF
usbcore: registered new interface driver cdc_ether
rndis_host 1-1.4:1.0 eth1: register 'rndis_host' at usb-f1050000.ehci-1.4, RNDIS device, 00:xx:yy:aa:bb:cc
usbcore: registered new interface driver rndis_host

But I had to enable it by editing /etc/network/interfaces

    allow-hotplug eth1
    iface eth1 inet dhcp

Now I had to replace that Mifi access point, but the new one is not automatically enabled. I’m assuming it shows up as eth2, and I may have to repeat this for a couple more routers.

How can I get it to automatically enable whatever new network I connect?
DHCP is fine.

#StackBounty: #debian #freeze #mc Midnight commander starting very long

Bounty: 50

Unable to start midnight commander under Ubuntu. It’s a server, where I was using it for a lont time always. Today I logged in and found mc hangs on start.

dims@sagittarius-a:~$ mc

and nothing happens.

Reinstall didn’t help.

Removing config

rm -rf .config/mc

didn’t help.

Removing global config

sudo rm /etc/mc

and reinstall causes

dims@sagittarius-a:/etc$ mc
sfs_init(): Warning: file /etc/mc/sfs.ini not found

i.e. didn’t help and config files didn’t restored dusring install by some reason.

What else can be tried?

UPDATE

Wow! It just loads long! No less than 60-100 seconds. It appeared while I was writing this. So the question persists: what does it do so long? Calculating mass of proton? How to wean it from this habit?

UPDATE 2

Reinstalling MC doesn’t help.

UPDATE 3

Recently I configured my globally the domain name, which I am using as default in my LAN. Now, the commands like

dims@sagittarius-a:~$ host anything
anything.MYDOMAIN is an alias for MYDOMAIN.
MYDOMAIN has address GLOBAL_IP_OF_MY_SITE_1
MYDOMAIN has address GLOBAL_IP_OF_MY_SITE_2

I read, that MC does some DNS lookup on startup and it can slow the process. I would like to understand, what is happening to make my own correct configuration, because answers in that question are incomplete.

Bounty: 50

How do I change the default session I get when I log in? I’m on Debian jessie. I tried changing settings on gdm3, tried installing lightdm and following this but it’s just not working.

For more specificity, I’m trying to default to gnome-classic instead of gnome. I want to turn on the computer, log in as any arbitrary user, and see gnome-classic, not gnome3 (preferably I’d remove the gnome3 default session, if there’s a way to do that).

#StackBounty: #debian #keyboard-layout #tails-os #dvorak How to add Dvorak in Debian greeter of installation media CD/USB?

Bounty: 100

I want to contribute a patch to this feature request Consider adding Dvorak in the default keyboard layout option list in the greeter in Tails OS so I am thinking how to do it in Debian 8.7 first.
I do not understand precisely how you can make such a change in the existing USB Live media.

I do know how to make a persistent live system as in the thread How do I make a persistent live USB of Ubuntu 16.04? but how to make a change in the existing live installation media is unknown to me because

  • There is an installation code in apt-get which creates the installation on USB. It is using some codes. How can you study those codes which is about the keyboard layout in the greeter?

#StackBounty: #ubuntu #debian #kvm-virtualization #telnet #proxmox Can't telnet a server from vps

Bounty: 50

i try to understand why i can’t telnet this server 213.132.48.107 from any of my VPSs.
Well this ip is for a mail server i don’t own but our emails are not received by this server. when i checked the log i saw this error:

554 5.7.1 You are not allowed to connect.
Connection closed by foreign host.

I thought i’m in black list so i tried to telnet to that server from all my VPSs (7 VPSs) and always get the same error.

telnet 213.132.48.107 25
Trying 213.132.48.107...
Connected to 213.132.48.107.
Escape character is '^]'.
554 5.7.1 You are not allowed to connect.

But when i try from a dedicate server i can telnet.

I have contacted the server admin but didn’t get any response. I still don’t see any reason for them to block my IP address. we just installed the server and it’s used for regular emails only.

Please help me

My VPSs run debian/ubuntu/centos and all created created by proxmox
