GExperts – when your predecessor has put it under the Tools menu
Posted by jpluimers on 2017/03/21
I totally forgot that GExperts can be under the Tools men
GExperts IDE configurationu (I’m so accustomed that Alt-X is GExperts and Alt-M is ModelMaker Code Explorer).
These keyboard shortcuts are only assigned when you install GExperts before you install ModelMaker Code Explorer.
If you reverse, then you have to fiddle by removing the ModelMaker Code Explorer expert, then re-add it.
Anyway: you can configure this in the “IDE” tab of the GExperts Configuration.
After that you have to restart the Delphi IDE to reflect the change.

When a ScanSnap ix500 blinks an orange light/LED/button
Posted by jpluimers on 2017/03/20
Still not sure why (as the WiFi here didn’t change) but I had the LED of my ScanSnap ix500 scan button light up orange instead of blue.
Via How to Connect More than One Mobile Device to Your ScanSnap iX500 [WayBack], I found out it means this:
If the light is orange, go to the ScanSnap Wireless Setup Tool and check the mobile connection.
Evernote suggests to have it re-connect over WPS [WayBack] but in as WPS has big security issues this is not a good idea.
So I hooked it up over USB and re-registered it to the WiFi connection. You can do this from both a Windows PC and Mac:
configure your ScanSnap iX500 to a different router, follow the step-by-step instructions here [WayBack]
If I ever want to use it on Linux: it is possible to get it to work, see 12.10 – Does the ScanSnap IX500 work with Ubuntu? – Ask Ubuntu

ducks: How Do I Find The Largest Top 10 Files and Directories On a Linux / UNIX / BSD?
Posted by jpluimers on 2017/03/20
Explains how to find out top 10 files and directories under Unix / Linux using sort and du command in human-readable format.
Interesting, especially
alias 'ducks=du -cks * | sort -rn | head'

defrag.exe: tracking an already in progress operation can be done from non-admin session
Posted by jpluimers on 2017/03/17
When you want to defrag.exe (the built-in Windows one, not the SysInternals Windows NT4 one, so make sure SysInternals comes last in your path) a volume, you have to run it with an elevated UAC Admin token.
But I just found out that you can do this without an Admin token:
C:\Windows\System32>Defrag.exe C: /t /v /u
Microsoft Drive Optimizer
Copyright (c) 2013 Microsoft Corp.
Tracking operation on (C:)...
Performing pass 2:
Free Space Consolidation: 31% complete...
This makes it much easier to separate monitoring scripting from execution.

Ctrl-T — www.voidtools.com • View topic – Everything window is ‘Always On Top’
Posted by jpluimers on 2017/03/17
If you use everything search from VoidTools, then don’t be surprised that pressing Ctrl-T makes it “Always On Top”:
Ctrl-T sets “Always On Top”
Of course this is not defined in “Tools” -> “Options”.
I forgot in which version this was introduced, as in the past I never stumbled over it on keyboards that have Ctrl and Alt reversed.

Decode URLs from The Great Suspender after a browser restart fails to reload them
Posted by jpluimers on 2017/03/16
Hosted at: Decode URLs from The Great Suspender after a browser restart fails to reload them
Converts URLs like these:
chrome-extension://klbibkeccnjlkjkiokjodocebajanakg/suspended.html#url=http%3A%2F%2Fwww.barryodonovan.com%2F2012%2F06%2F29%2Fmigrating-svn-with-branches-and-tags-to-git
back into
http://www.barryodonovan.com/2012/06/29/migrating-svn-with-branches-and-tags-to-git
Source below.
It decodes a URL encoded by The Great Suspender which is a cool Google Chrome plugin that suspends pages after some idle time.
The uncool thing is that when Google Crome restarts after a crash (it’s software, it does that, especially as it consumes truckloads of memory and is full of memory leaks) it often fails to restore some (but not many) of the suspended pages into a usable state: it shows only the encoded URLs.

Fixing 0x858C001E error on SQL Server 2012/2014 updates
Posted by jpluimers on 2017/03/16
A long time ago I wrote about Fixing 84b40000 error on SQL Server 2008 updates (like KB2977321 and KB2285068).
The same holds for error 0x858C001E errors when updating SQL Server 2012 and 2014:
For x86 systems, ensure these directories are not compressed:
C:\Program Files\Microsoft SQL Server
C:\Program Files\Microsoft SQL Server Compact EditionFor x64 systems, ensure these directories are not compressed:
C:\Program Files\Microsoft SQL Server
C:\Program Files x86\Microsoft SQL Server
C:\Program Files x86\Microsoft SQL Server Compact Edition
Sources:
- Security Update for SQL Server 2012 Service Pack 2 (KB3045321) update problem – error code 858C001E, and error code 1642
- SQL Server 2014 update FAILS — Error Code 858C001E – Microsoft Community

Microsoft Remote Desktop 8 on OS X stores RDP configuration in com.microsoft.rdc.mac.plist and passwords in keychain
Posted by jpluimers on 2017/03/15
One day I write some scripts based on:
- /usr/bin/plutil
- /usr/libexec/PlistBuddy
Some starting materials are at:
- How To: Create a Microsoft Remote Desktop 8 Connection | macmule
- com.microsoft.rdc.mac.plist needs to be binary for RDP to work and XML to edit it manually (use plutil to do the conversion)
- macmule/Create-a-Microsoft-Remote-Desktop-8-Connection
- Microsoft Remote Desktop version 8 – JAMF Nation
- remote desktop – Where does Microsoft RDP 8 for Mac store it’s configuration – Ask Different
- .rdp files are now using the XML plist format: Microsoft releases Remote Desktop 8.0 for Android, iOS and Mac | OfficeforMacHelp.com
- CoRD .rdp files seem to share the same XML plist format: Transfer CoRD bookmarks to Microsoft Remote Desktop | OfficeforMacHelp.com
A thing I learned is that the Microsoft Remote Desktop 8 is basically a rebranded iTap RDP (it looks like Microsoft bought iTap RDP for Mac, as iTap RDP for Mac is now discontinued)

How to secure memory? – Medo’s Home Page
Posted by jpluimers on 2017/03/15
Sometime you might want to protect your data in memory – the greatest example is when dealing with anything related to passwords. It is simply not smart to keep that data around in a plain-text. In .NET there are multiple methods you can use for this purpose, starting with SecureString, ProtectedMemory, and my favorite ProtectedData.…
