Disable screensaver using registry settings

Posted by jpluimers on 2015/12/30

This is what I needed:

:: http://www.windows-commandline.com/disable-screensaver-registry-settings/
reg add "HKEY_CURRENT_USER\Control Panel\Desktop" /v ScreenSaveActive /t REG_SZ /d 0 /f

And this one to verify the current settings:

:: http://www.windows-commandline.com/disable-screensaver-registry-settings/
:: possible names
:: ScreenSaveActive
:: ScreenSaveTimeOut
:: ScreenSaverIsSecure
reg query "HKEY_CURRENT_USER\Control Panel\Desktop" | findstr /I /C:"ScreenSave"

Command Line Kung Fu: Episode #43: Users & Groups

Posted by jpluimers on 2015/12/29

I needed to compare the local group memberships on a few systems.

I knew there is the distinction between

  • net group (which despite documentation requires /domain as it does not support local groups: you get a nice NET HELPMSG 3515 error) and
  • net localgroup (which can either run locally or with /domain).

So I came up with this batch file thanks to Command Line Kung Fu:

:: http://blog.commandlinekungfu.com/2009/06/episode-43-users-groups.html
for /F "skip=4 delims=*" %%g in ('net localgroup ^| find /v "The command completed successfully"') do @net localgroup "%%g"

It can be done in PowerShell too, but is more work.

Based on that and Beyond Compare I created some diff scripts.

Mac OS X: integrating Beyond Compare 4 into SourceTree 2.x

Posted by jpluimers on 2015/12/28

Unlike SourceTree for Windows, SourceTree for Mac still doesn’t automagically detect Beyond Compare even though that has been available for Mac OS X since :  [SRCTREE-2092] Add built-in support for Beyond Compare version 4 – Atlassian JIRA.

Even modifying my ~/.gitconfig didn’t work, but manual configuration did. Here are the steps:

  1. Start the UI version of Beyond Compare
  2. Select the Beyond Compare menu, install the command-line tools

Steps for adjusting a whiteboard photo in Gimp

Posted by jpluimers on 2015/12/28

A long time ago, I wrote about Steps for adjusting a whiteboard photo in Paint.NET.

GIMP does an even better job with these steps:

Once: install the clean-whiteboard-photo script

  1. Visit https://github.com/kyleburton/sandbox/blob/master/gimp/clean-whiteboard-photo.scm
  2. Click “raw”
  3. Hit “Ctrl-S” to save the file as file-type “*.txt” and file-name  “%temp%\clean-whiteboard-photo_scm.txt”
  4. Go to the folder “%temp%”
  5. In there,
    1. select the firle  “clean-whiteboard-photo_scm.txt”,
    2. change it into  “clean-whiteboard-photo.scm”,
    3. copy the file
  6. Go to the folder  “C:\Program Files\GIMP 2\share\gimp\2.0\scripts”
  7. Paste the file (you need to confirm Administrator rights through UAC)

The above steps will add this menu option to GIMP: menu “Filters” -> “Whiteboard” -> “Clean whiteboard photo”

For every picture: make it less ugly

  1. Start GIMP 2
  2. Open the picture
  3. With the “Rectangle Select” Tool (R), select the area of the whiteboard that you want to enhance
    1. If the area is not completely rectangular, make the selection large enough to cover everything needed in the final picture
  4. Only when the selection needs adjustment to make it rectangular:
    1. Choose the “Perspective” Tool (Shift-P)
    2. Drag the incorrect corners until the selection is rectangular
    3. In the “Perspective” tool window, click “Transform” to confirm
    4. The selection now is not rectangular any more, so deselect everything:
      1. In the menu, choose “Select” -> “None” (Shift-Ctrl-A)
  5. With the “Rectangle Select” Tool (R), select the area of the whiteboard that you want to enhance
  6. In the menu, choose “Image” -> “Fit canvas to selection”
  7. In the menu, choose “Filters” -> “Whiteboard” -> “Clean whiteboard photo”
  8. Click next to the selection to confirm the cleanup
  9. In the menu, choose “File” -> “Export”
    1. Save the file under a new name (often a PNG extension will give better compression than JPEG, and has less artifacts as well)

“Sealed, non-spillable”. Yeah right: @APCbySchneider batteries do leak. How to clean lead acid battery leaking residue.

Posted by jpluimers on 2015/12/26

I found out the hard way that the so called APC “Sealed, non-spillable” lead acid batteries inside their UPS systems do leak when used normally.

So I head to clean up before the damage would get bigger.

A few links on how to clean:

This is what you need:

  • Gloves
  • Goggles
  • Baking Soda (Sodium bicarbonate, in Dutch Zuiveringszout*)
  • Water
  • Wrench
  • Wire brush
  • Steel wool
  • Soft cloth(s)
  • Petroleum jelly (or in Dutch: vaseline** that is acid and fragrance-free)

Baking soda paste: 3 parts baking soda and 1 part water.

Baking soda solution: 1 parts baking soda in 10 parts water.

* Zuiveringszout: Natriumwaterstofcarbonaat (natriumbicarbonaat, dubbelkoolzure soda): E-nummer E 500 (ii).

In The Netherlands, you can get it expensively as “bakpoeder” ingredient (baking powder) or cheaply as cleaning agent called Zuiveringszout.

** Vaseline usually is petroleum jelly with extra ingredients, be sure to get the pure white one that is acid and fragrance free.

Follow-up: The details of one of my UPS-es. There is no such thing as leak free lead acid batteries, despite APC saying so…

USB-C charging cables: not always as good as you’d think

Posted by jpluimers on 2015/12/25

Merry X-mas sorting out your cables (:

Some interesting links that all come down to: make sure your USB-C cable is compliant before you start really using it.

you cannot be sure that cables Benson tested good are always good. Trust me, it happened to me. Knowing the ASINs/EANs of good cables, I went into local stores and bought a number of presumably good cables. Know what? They were bad. Might be that vendors recently changed their cables and there are still batches of bad ones out there, still with the same ASIN/EAN codes. So just be careful!

and

Having a weaker than 3A charger is actually a risk factor because the device being charged will always try to charge at 3 and if the older adapter can’t handle 3A, that is when it might be
