No, Visual Studio Community 2017 is not a 30 day trial – via Stack Overflow

Posted by jpluimers on 2019/04/30

Visual Studio Community 2017 needs a license renewal every ~30 days with a Microsoft account: [WayBack] Visual Studio Community 2017 is a 30 day trial? – Stack Overflow.

This means it is not a trial, but it does not a Microsoft account, and communicate with it every ~30 days which you can get at [WayBack] Microsoft account | Sign In or Create Your Account Today.

Messages you can get:

  • “We could not download a license. Please check your network connection or proxy settings” – meaning: sign in with a Microsoft account by clicking “Add an account…”
  • “We could not download a license, Please ensure your accounts are authenticated.” – meaning you have to click “Reenter your credentials”

bash – aliasing cd to pushd – is it a good idea? – Unix & Linux Stack Exchange

Posted by jpluimers on 2019/04/30

On my research list: [WayBackbash – aliasing cd to pushd – is it a good idea? – Unix & Linux Stack Exchange

It has a nice discussion on complements to pushd/popd/cd/dirs including a very nice set of navd scripts that eases the navigation of the directory stack.

I found it because the ESXi busybox does not have pushd and popd and a cd won’t work from inside a shell script: [WayBacklinux – Why doesn’t “cd” work in a bash shell script? – Stack Overflow

It also made me find out that the ESXi busybox does support cd - to go to the previous directory. More info on that cd syntax is at [WayBack] bash – Difference between “cd -” and “cd ~-” – Unix & Linux Stack Exchange

compiling – Where do executables look for shared objects at runtime? – Unix & Linux Stack Exchange

Posted by jpluimers on 2019/04/30

Thanks Gilles for answering [WayBackcompiling – Where do executables look for shared objects at runtime? – Unix & Linux Stack Exchange.

Abstract:

In a nutshell, when it’s looking for a dynamic library (.so file) the linker tries:

  • directories listed in the LD_LIBRARY_PATH environment variable (DYLD_LIBRARY_PATH on OSX);
  • directories listed in the executable’s rpath;
  • directories on the system search path, which (on Linux at least) consists of the entries in /etc/ld.so.conf plus /lib and /usr/lib.

osx lion – osx change printer ip address without adding new printer – Super User

Posted by jpluimers on 2019/04/29

From [WayBack] osx lion – osx change printer ip address without adding new printer – Super User:

Q

Is there a way to change a printer’s IP address in OSX (Lion) without having to add a new printer? I did find Printer IP Remedy, but was curious if there was an ‘official’ method.

A

You can do this in the CUPS web interface with the following steps:

  1. Open Terminal.app and run cupsctl WebInterface=yes. This enables the CUPS web interface
  2. Open http://127.0.0.1:631/printers in your web browser
  3. Click on the printer you want to change. From the “Administration” drop down, select “Modify Printer”.
  4. Log in with your local admin account
  5. Select the new printer IP either from “Discovered Network Printers” or add it manually with “Other Network Printers”. Make sure that you keep the same connection protocol as it says in “Current Connection” (for me, this was LPD).

Once you’re done with this, Mac OS X will directly print to the new IP address. There is no need to reboot or so. If you want to disable the CUPS web interface again, run cupsctl WebInterface=no.

The CUPS solution works splendid in MacOS as well, so there was no need for [Archive.is] Printer IP Remedy 1.3 free download for Mac | MacUpdate.

Without the CUPS web interface enabled, the web-interface at http://127.0.0.1:631/printers looks like this:

Web Interface is Disabled

The web interface is currently disabled. Run “cupsctl WebInterface=yes” to enable it.

After enabling it like the CUPS web interface wit cupsctl WebInterface=yes, you can see I have the same printer configured multiple times with different communication protocols and output languages:

Printers

Search in Printers:

Showing 6 of 6 printers.

Queue Name Description Location Make and Model Status
OKI_MC342_36855D OKI-MC342-PSO-36855D Office MC342-AirPrint Idle
OKI_MC342_36855D_PCL OKI-MC342-36855D PCL 1060NP-Office Generic PCL Laser Printer Idle
OKI_MC342_IPP OKI-MC342-IPP Office Generic PostScript Printer Idle
OKI_MC342_LPR OKI-MC342-LPR Office Generic PostScript Printer Idle

The first two printers were mapped by DNS, but the last two were mapped by IP address.

Changing the IP address was simple:

  1. Click on each link
  2. Select “Modify printer”
  3. Authenticate (only needed for the first printer change)
  4. For IPP: note the current address (like ipp://192.168.71.52/), then
    1. Choose “Internet Printing Protocol (ipp) “
    2. Click “Continue”
    3. Enter the correct ipp://…./ address (help is at http://127.0.0.1:631/help/network.html or http://127.0.0.1:631/help/network.html?PRINTABLE=YES)
    4. Click “Continue”
    5. Check the modifications (optionally change Description/Location)
    6. Click “Continue”
    7. Keep the driver
    8. Click “Modify printer”
  5. For LPD, note the current address (like lpd://192.168.71.52/), then follow the IPP steps, but choose “LPD/LPR Host or Printer” and enter a valid lpd address.

This is also the place where you can change “Default options”, like paper size (which – for all but the first – somehow defaulted to US Letter 11 inch, while it is actually filled with A4 paper).

At the end, disable the web interface: cupsctl WebInterface=no.

LSI 9260-8i: all disks are “Unconfigured bad”

Posted by jpluimers on 2019/04/29

This is the second time in about 6 years that somehow after an ESXi reboot all of the drives on an LSI 9260-8i controller got into the state “Unconfigured bad”.

The trick to solve this is to:

  1. go into the WebBIOS of the LSI card
  2. mark all drives as “Unconfigured good”
  3. rescan for devices
  4. import the existing configuration
  5. reboot

More in depth steps with images:
