OpenCandy – Wikipedia

Posted by jpluimers on 2020/11/06

Hmm, one of my machines contained OpenCandy – Wikipedia as found by Malwarebytes (software) – Wikipedia:

Tracking back the installation, revealed it came with ImgBurn 2.5.8.0, which is now on my black-list.

In my case this was how to remove it:

rd /s /q %AppData%\OpenCandy

This is not universal; you might need to take additional measures like in [WayBack] How to Remove PUP.Optional.OpenCandy (Removal Guide).

I use this batch-file to get the most recent Malwarebytes and Chameleon:

get-malware-bytes.bat 

:: redirects to something like wget https://data-cdn.mbamupdates.com/web/mb3-setup-consumer/mb3-setup-consumer-3.6.1.2711-1.0.508-1.0.8211.exe
wget --content-disposition https://downloads.malwarebytes.com/file/mb3/
:: redirects to something like wget https://data-cdn.mbamupdates.com/web/mbam-chameleon-3.1.33.0.zip
wget --content-disposition https://downloads.malwarebytes.com/file/chameleon/

If you do not have wget on your system, then try this PowerShell alternative (which does not show progress) via [WayBack] Windows batch file file download from a URL – Stack Overflow

:: in case you do not have wget:
powershell -Command "(New-Object Net.WebClient).DownloadFile('https://downloads.malwarebytes.com/file/mb3/', 'mb3.exe')"
powershell -Command "(New-Object Net.WebClient).DownloadFile('https://downloads.malwarebytes.com/file/chameleon/', 'chameleon.exe')"
:: note these do not show progress!

Rebooting a Linux server unattended – twm’s blog

Simple, but I keep forgetting where Linux has short/long command options and short/long verbs.

I need to dig into IPP / driverless printer confuguration

Posted by jpluimers on 2020/09/07

It looks like I need to learn about IPP and driverless based on [WayBack] TIL that your Linux desktop can probably use your somewhat recently made printer, efficiently, with all major features exposed, without needing to download a ton of vendor shitware, without needing to find a PPD file in the depths of hell, without needing to pay extra for explicit PostScript 3 support, and without needing to accept that it will do 0.2 instead of 20 pages per minute because the in-printer PostScript rasterizer runs on a Z80…. – Maik Zumstrull – Google+.

So here are some links:

When adding my printer in the Chrome tool, it can properly detect it:

bash – convert comma separated values into a list of values using shell script – Stack Overflow

Posted by jpluimers on 2020/09/07

For a simple comma separated list (no quotes), I was expecting a sed script (and indeed it is possible), but tr is more elegant:

Use tr to change , into newlines:

tr , "\n" < list.txt

See https://en.wikipedia.org/wiki/Tr_(Unix)

find – display only files starting with . (hidden) – Unix & Linux Stack Exchange

Posted by jpluimers on 2020/08/21

find . -type f -name '\.*' -print

Must work if you want list every hidden file down in the directory hierarchy.

This sort of works on Linux, but fails on VMware ESXi (on Linux it only works when applying -maxdepth 1, deeper levels fails because they list all files where the top directory starts with a .):

If you want hidden files and hidden directories, without . and .. :

find -regex '\./\..+' -print

This works on both Linux and VMware ESXi:

If you want hidden files and hidden directories, without . and .. :

find . \( -type f -o -type d \) -name '\.*' -print

Based on:

Dirvish

Posted by jpluimers on 2020/08/17

I think it was Thomas Mueller pointing to this, but I’m not sure as I found it in a browser tab from long ago: [WayBack] Welcome to Dirvish

Dirvish is a fast, disk based, rotating network backup system.

With dirvish you can maintain a set of complete images of your filesystems with unattended creation and expiration. A dirvish backup vault is like a time machine for your data.

Dirvish was originally created by jw schultz .

Comparing versions with wildcards and without them (for instance for semantic versioning)

Posted by jpluimers on 2020/08/12

For a project I’m going to be in need to compare version numbers.

I’m not sure yet if I need wildcards, or can leave them out (but for partial semantic versioning, I might need them).

Below a bunch of links that should get me started.

From a quick glance: versioning is hard, comparing even harder.

On versioning in general

Numeric versioning (usually without wildcards):

On semantic versioning (SemVer for short):

On the C# Version class (which handles most of semantic versioning except: leading zero’s, very large numbers, non-numeric release specifiers)

Interesting idea, but not sustainable: using floating point values to compare versions:

On wildcards:

Via: [WayBack] Anyone tips for a TVersion structure that supports at max quad digits or wildcards and comparison? Like 3.2 matching 3.2.5.7, but not matching 3.3.4.28 ? – Jeroen Wiert Pluimers – Google+
