Batch files and parentheses

Posted by jpluimers on 2018/10/31

Answering [WayBack] delphi – post-build event with multiple if/copy combinations only execute if first file does not exist – Stack Overflow made me do a quick search for parentheses handling in batch files. TL;DR: it is a mess.

But it reveals some interesting links:

PowerShell: measuring size of the Windows TEMP directory

Posted by jpluimers on 2018/10/31

Due some issues in Windows, every now and then the Windows TEMP directory gets huge.

This script helps measuring the recursive size of that folder:

$WindowPath = [System.Environment]::GetFolderPath([System.Environment+SpecialFolder]::Windows)
$WindowTempPath = Join-Path -Path $WindowPath -ChildPath "TEMP"
$Result = Get-ChildItem $WindowTempPath -Recurse | Measure-Object -Property Length -Sum
$RecursiveSumInBytes = $Result.Sum
Write-Host "$RecursiveSumInBytes"

It uses these tricks:

  • Accessing native .NET types; in this case [WayBack] Environment.SpecialFolder Enumeration (System) to get the “The Windows directory or SYSROOT. This corresponds to the %windir% or %SYSTEMROOT% environment variables. Added in the .NET Framework 4.”
  • Assuming the Windows TEMP directory is always named that way.
  • Using [WayBack] Join-Path to combine a base path with a child path without worrying about the path delimiter.
  • Recursively enumerating all items in that folder using [WayBack] Get-ChildItem.
  • Aggregating with [WayBack] Measure-Object over the Length property of each Child-Item to determine their Sum.

After this, cleaning up uses two more tricks:

$WindowPath = [System.Environment]::GetFolderPath([System.Environment+SpecialFolder]::Windows)
$WindowTempPath = Join-Path -Path $WindowPath -ChildPath "TEMP"
Get-ChildItem $WindowTempPath -Recurse | foreach { Remove-Item $_.FullName -Recurse }

Delphi: create implementations in the same order as the interface section and sync method signatures

Posted by jpluimers on 2018/10/30

An interesting question at [WayBack] Previously i have not been big on IDE plugins.So i’m blatantly asking for pointers on the following, i.e. is there already such beasts? Or maybe i’m i… – Dany Marmur – Google+:

… asking for pointers on the following…

Crtl+C – create implementations in the same order as the interface section?
Ctrl+C – adjust the signature of the method the cursor is on interface if implementation and vice versa.

I realise they can both be very tricky to implement. Second function might not be able to handle overloads.

From that thread, a few things you might want to try:

  • [WayBack] ModelMaker Code Explorer can do both.
  • [Archive.is] DDevExtensions version 2.82 (2014-08-25): introduced “Added: Disable Alpha-Sort Class Completion (Default off)”
  • More recent versions of the IDE (I think 10.0) incorporated the “sync prototypes” action (Shift+Ctrl+Alt+P) from Castalia.

xkcd: Free Speech

Posted by jpluimers on 2018/10/29

[WayBack] xkcd: Free Speech is worth repeating every now and then:

Title text: I can’t remember where I heard this, but someone once said that defending a position by citing free speech is sort of the ultimate concession; you’re saying that the most compelling thing you can say for your position is that it’s not literally illegal to express.

Transcript

Cueball: Public Service Announcement: The Right to Free Speech means the government can’t arrest you for what you say.
Cueball: It doesn’t mean that anyone else has to listen to your bullshit, or host you while you share it.
Cueball: The 1st Amendment doesn’t shield you from criticism or consequences.
Cueball: If you’re yelled at, boycotted, have your show canceled, or get banned from an Internet community, your free speech rights aren’t being violated.
Cueball: It’s just that the people listening think you’re an asshole,
[A picture of a partially open door is displayed.]
Cueball: And they’re showing you the door.

Be sure to read [WayBack] 1357: Free Speech – explain xkcd too.

Map of the internet precursor ARPA network as of May 1973 – David Newbury

Posted by jpluimers on 2018/10/29

Today’s internet day anniversary only started in 2005. But the networks leading to the internet are a lot older and date as far back as the late 1960s. In fact [WayBack] Internet Day, October 29th refers to the first ARPA network communication taking place in 1969.

About two years ago, David Newbury published this piece of history from 1973: a map of the ARPA network (later called ARPANET).

[WayBack] David Newbury: “Going through old papers my dad gave me, I found his map of the internet as of May 1973. The entire internet. https://t.co/0krvYoRGav”

The resulting thread has loads of more interesting pictures which I tried to save in the Wayback Machine as not even Wikipedia seems to have them.

It also includes a discussion on the meaning of the zig-zag line to Hawaii, the connection to London (UK that is, not USA) later that year and even earlier state of the late 1960s.

Worth reading (:

Here are some references to messages and links from the Twitter thread:

Install on openSUSE / SLES – Zabbix.org

Posted by jpluimers on 2018/10/29

Interesting: [Archive.is] Install on openSUSE / SLES – Zabbix.org is possible and there are packages for this on the OpenSuSE site itself for the various kinds of distributions.

For instance, Tumbleweed is at http://download.opensuse.org/repositories/server:/monitoring/openSUSE_Tumbleweed/

Good introductions on Zabbix are via [WayBack] Stephen Fritz on Systems Engineering: Installing and Configuring Basic Zabbix Functionality on Debian Wheezy who has a [Archive.is] zabbix tag.

Other links are at Welcome to workaround.org – tips around open source and Linux stuff.

And there is www.zabbix.com/documentation
