Supermicro | Products | Motherboards | Xeon® Boards | X9SRi-3F

Posted by jpluimers on 2021/03/12

I still like this board: Supermicro | Products | Motherboards | Xeon® Boards | X9SRi-3F.

It has been in a storage solution for a while, uses OK power, has not many SATA ports, but enough slots for expansion cards, and comes with two network connections and 8 slots which I fitted with a total of 256 gibibyte of memory.

Some links, as SuperMicro tends to hide them behind POST requests:

Note that IPMI over je Java Web Start.app runs into certificate signing issues, so better use Supermicro IPMIViewer for this:

IPMIView links via:

The errors when running the KVM Console from your web browser are waved away by SuperMicro, but more and more people bump into them:

Enable Block at First Sight to detect malware in seconds | Microsoft Docs

Posted by jpluimers on 2021/03/12

On my reading list, because I saw it suddenly enabled on a domain based Windows network:

[WayBack] Enable Block at First Sight to detect malware in seconds | Microsoft Docs

Enable the Block at First sight feature to detect and block malware within seconds, and validate that it is configured correctly.

It seems to have been introduced early 2018: Windows Defender – Wikipedia: Advanced Features

Windows 10’s Anniversary Update introduced Limited Periodic Scanning, which optionally allows Windows Defender to scan a system periodically if another antivirus app is installed.[5] It also introduced Block at First Sight, which uses machine learning to predict whether a file is malicious.[21]

There is a BAFS – Windows Defender Testground for which you need a Microsoft account.

Waarom stemmen we in Nederland niet online? | NU – Het laatste nieuws het eerst op NU.nl

Posted by jpluimers on 2021/03/11

Mooi stuk [Wayback] Waarom stemmen we in Nederland niet online? | NU – Het laatste nieuws het eerst op NU.nl

Is het veilig om tijdens de coronacrisis in het stemhokje te staan, vragen veel mensen zich op dit moment af. Waarom stemmen we nu eigenlijk niet online?

Samenvatting:

  • Vrij stemmen is buiten het stemhokje niet goed te controleren
  • Stemgeheim is biuten het stemhokje niet goed te controleren

Eigenlijk gelden beide ook voor briefstemmen.

Wat voor mij ook belangrijk is, is dat het uitleggen van normaal stemmen (inclusief controles en hertellingen) heel eenvoudig is uit te leggen, maar dat dit bij elektronisch stemmen veel moeilijker is.

Vanwege het belang van inzichtelijkheid zie ik online stemmen voorlopig daarom niet komen.

Mikrotik: script to set clock to Amsterdam, enable ntp, then show latest ntp correction

Posted by jpluimers on 2021/03/11

For my script list:

/system ntp client set enabled=yes server-dns-names=0.pool.ntp.org,1.pool.ntp.org,2.pool.ntp.org,3.pool.ntp.org
/delay 10
/system ntp client print

If the delay was long enough, you will see output like this:

             enabled: yes
         primary-ntp: 0.0.0.0
       secondary-ntp: 0.0.0.0
    server-dns-names: 0.pool.ntp.org,1.pool.ntp.org,2.pool.ntp.org,3.pool.ntp.org
                mode: unicast
       poll-interval: 15m
       active-server: 149.210.230.59
    last-update-from: 149.210.230.59
  last-update-before: 29s290ms
     last-adjustment: 702us

If the delay was too short, the lines after mode will not be present.

GitHub – pastpages/savepagenow: A simple Python wrapper for archive.org’s “Save Page Now” capturing service

Posted by jpluimers on 2021/03/11

This makes it way easier to save WayBack content:

[WayBack] GitHub – pastpages/savepagenow: A simple Python wrapper for archive.org’s “Save Page Now” capturing service

A poor-mans alternative is the below bash script from [WayBack] Saving of public Google+ content at the Internet Archive’s Wayback Machine by the Archive Team has begun : plexodus:

For Linux, MacOS / OSX, BSD, and other Unix-like operating systems (including Android with Termux, or Windows, with a Unix/Linux environment), the following script (I’ve saved this as archive-url) will archive the requested URL:

#!/bin/bash
# archive-url
# Archive selected URL at the Internet Archive

curl -s -I -H "Accept: application/json" "https://web.archive.org/save/${1}" |
grep '^x-cache-key:' | sed "s,https,&://,; s,\(${1}\).*$,\1,"

Save that to your execution path (I’ve chosen ~/bin, you might use /usr/local/bin or another location on your $PATH, and invoke as, say (again referring to the G+MM homepage):

$ archive-url https://plus.google.com/communities/112164273001338979772

If you have a list of URLs in a file (or pipelined from command output), you can request all of them to be archived in a simple bash loop. I’m using xargs here to run ten simultaneous requests from the file gplus-urllist:

cat gplus_urllist | while read url do xargs -I{} -P 10 archive-url {}; done

I’ve run this on over 10,000 URLs over a modest residential broadband connection in a hair over two hours.

Note that such requests trigger an archive by the Internet Archive from one of its archiving nodes, you’re not sending the page to the Archive yourself. In particular, archival from regions defaulting to another language may result in the Google+ site content (but not post or comments) being in a different language. I’ve frequently seen my pages turning up in Japanese, for instance.

GExperts grep search: skipping searching certain files, irrespective of their directory

Posted by jpluimers on 2021/03/11

Especially when including [WayBack] form files (dfm now, but in the past also nfm and xfm) in your search, you might want to exclude one or more of them, for instance when they do not adhere to the form file syntax.

One of such files is for instance [WayBack] jcl/ExceptDlg.CBuilder32.dfm at master · project-jedi/jcl · GitHub. It has the contents is NONE (by intent, just like the corresponding .h and .cpp files, as only the Delphi equivalents .dfm and .pas have been implemented).

Doing this was way easier than I thought: just put ExceptDlg.CBuilder32.dfm in the “Exclude Dirs” field – which also excludes files. How cool is that!

Applying .patch File From Git – Easyread – Medium

Posted by jpluimers on 2021/03/10

Next time I need to apply a patch file directly from git itself, I need to re-read [WayBack] Applying .patch File From Git – Easyread – Medium.

Without git, just run the patch command as per [WayBack] What is a patch in git version control? – Stack Overflow

The git workflow for the above git scenario is this one:

VS2017 Community .vsconfig file – Visual Studio Community workload and component IDs | Microsoft Docs

Posted by jpluimers on 2021/03/10

When I need to find out what components match my below installed .vsconfig component IDs for Visual Studio 2017 community edition, I can find them in: [WayBack] Visual Studio Community workload and component IDs | Microsoft Docs: Use workload and component IDs to install Visual Studio by using the command line or to specify as a dependency in a VSIX manifest.

{
    "version": "1.0",
    "components": [
        "Microsoft.VisualStudio.Workload.ManagedDesktop",
        "Microsoft.VisualStudio.Workload.NativeDesktop",
        "Microsoft.VisualStudio.Workload.Universal",
        "Microsoft.VisualStudio.Workload.NetWeb",
        "Microsoft.VisualStudio.Workload.Azure",
        "Microsoft.VisualStudio.Workload.Python",
        "Microsoft.VisualStudio.Workload.Node",
        "Microsoft.VisualStudio.Workload.Office",
        "Microsoft.VisualStudio.Workload.NetCrossPlat",
        "Microsoft.VisualStudio.Workload.VisualStudioExtension",
        "Microsoft.VisualStudio.Workload.NativeCrossPlat",
        "Microsoft.VisualStudio.Workload.NetCoreTools",
        "microsoft.net.componentgroup.targetingpacks.common",
        "microsoft.visualstudio.component.entityframework",
        "microsoft.visualstudio.component.debugger.justintime",
        "microsoft.visualstudio.component.vc.diagnostictools",
        "microsoft.visualstudio.component.vc.cmake.project",
        "microsoft.visualstudio.component.vc.atl",
        "microsoft.visualstudio.component.vc.testadapterforboosttest",
        "microsoft.visualstudio.component.vc.testadapterforgoogletest",
        "microsoft.visualstudio.componentgroup.web.cloudtools",
        "microsoft.visualstudio.component.aspnet45",
        "microsoft.component.azure.datalake.tools",
        "microsoft.visualstudio.componentgroup.azure.resourcemanager.tools",
        "microsoft.visualstudio.componentgroup.azure.cloudservices",
        "microsoft.visualstudio.component.azure.mobileappssdk",
        "microsoft.visualstudio.component.azure.servicefabric.tools",
        "microsoft.component.cookiecuttertools",
        "microsoft.component.pythontools.web",
        "component.cpython3.x64",
        "microsoft.visualstudio.component.teamoffice",
        "component.google.android.emulator.api27",
        "component.linux.cmake"
    ]
}

This comes in very useful when installing Visual Studio 2017 through chocolatey:

chocolatey install -yes visualstudio2017community
:: "Microsoft.VisualStudio.Workload.ManagedDesktop", 
chocolatey install -yes visualstudio2017-workload-manageddesktop
:: "Microsoft.VisualStudio.Workload.NativeDesktop", 
chocolatey install -yes visualstudio2017-workload-nativedesktop
:: "Microsoft.VisualStudio.Workload.Universal", 
chocolatey install -yes visualstudio2017-workload-universal
:: "Microsoft.VisualStudio.Workload.NetWeb", 
chocolatey install -yes visualstudio2017-workload-netweb
:: "Microsoft.VisualStudio.Workload.Azure", 
chocolatey install -yes visualstudio2017-workload-azure
:: "Microsoft.VisualStudio.Workload.Python", 
chocolatey install -yes visualstudio2017-workload-python
:: "Microsoft.VisualStudio.Workload.Node", 
chocolatey install -yes visualstudio2017-workload-node
:: "Microsoft.VisualStudio.Workload.Office", 
chocolatey install -yes visualstudio2017-workload-office
:: "Microsoft.VisualStudio.Workload.NetCrossPlat", 
chocolatey install -yes visualstudio2017-workload-netcrossplat
:: "Microsoft.VisualStudio.Workload.VisualStudioExtension", 
chocolatey install -yes visualstudio2017-workload-visualstudioextension
:: "Microsoft.VisualStudio.Workload.NativeCrossPlat", 
chocolatey install -yes visualstudio2017-workload-nativecrossplat
:: "Microsoft.VisualStudio.Workload.NetCoreTools", 
chocolatey install -yes visualstudio2017-workload-netcoretools

Debouncing and Throttling Explained Through Examples | CSS-Tricks

Posted by jpluimers on 2021/03/10

TL;DR of https://css-tricks.com/debouncing-throttling-explained-examples/:

  • debounce: Grouping a sudden burst of events (like keystrokes) into a single one.
  • throttle: Guaranteeing a constant flow of executions every X milliseconds. Like checking every 200ms your scroll position to trigger a CSS animation.
  • requestAnimationFrame: a throttle alternative. When your function recalculates and renders elements on screen and you want to guarantee smooth changes or animations. Note: no IE9 support.
