Windows Services Dependency Viewer – Home

Posted by jpluimers on 2018/11/12

Cool tool: [WayBackWindows Services Dependency Viewer – Home:

Windows Services Dependency Viewer is a simple tool that provides the following information:

  • Windows service dependent and antecedent services
  • Services grouped by process
  • Service details (from Win32_Service WMI class)
  • Service process details (from Win32_Process WMI class

This tremendously helps getting an overview of which Windows Services to monitor for running state: if for instance you need monitor SMTP, then you do not need to monitor Event Log as that is a requirement.

Zabbix user groups and user type

Posted by jpluimers on 2018/11/12

Like any product documentation, Zabbix’ is shattered and terse.

So here is how I ensured a specific user could edit the items of hosts:

  1. Added new user group named Administer Configuration Host Items containing user Example having these read-write composing permissions:
    • Applicatie ontwikkel test
    • Applicatie productie Approve demo VPN
    • servers Dbases Kantoor applicaties
  2. Changed User type of user named Example from Zabbix User to Zabbix Admin so access to the Configuration tab is granted.

See 2 Permissions [Zabbix Documentation 3.0] for User type explanation; excerpt:

Zabbix Admin: The user has access to the Monitoring and Configuration menus. The user has no access to any host groups by default. Any permissions to host groups must be explicitly given.

It looks like gmail finally understands Outlook Calendar entries

Posted by jpluimers on 2018/11/12

For a very long time, gMail did nothing with Outlook Calendar entires.

So I had to view at the message source, then translate them to Google Calendar entries myself.

--_000_430b30b9ffd74d959b74ab7ba778b487ultrawarenl_
Content-Type: text/calendar; charset="utf-8"; method=REQUEST
Content-Transfer-Encoding: base64

...

As of late, they seem to be processed into Google Calendar compatible entries. Nice!

Renate Groenewold on Twitter: “Thanks @UltrawareBV dat @marijejoling en ik jullie mochten inspireren, motiveren en in beweging brengen met een presentatie en een circuittraining! #vitaliteit #duurzameinzetbaarheid #teambuilding #fun… “

[WayBackRenate Groenewold on Twitter: “Thanks @UltrawareBV dat @marijejoling en ik jullie mochten inspireren, motiveren en in beweging brengen met een presentatie en een circuittraining! #vitaliteit #duurzameinzetbaarheid #teambuilding #fun… “

This was so much fun! Not just because doing circuit training with ex Dutch top skaters is really insightful, but especially their explanation on what happens on the mental level what happens when you suddenly have to stop performing at the world top level.

In my case, today will be my final marching performance with Adest Musica after al almost 40 year marching career, of which the last 30+ years at the world top level.

It is also the final performance of our show “The Composer” which won world second place in the top league in 2017 during the quadrennial World Music Contest in Kerkrade.

So there is one more chance to see this show, at this event (there are just a few more tickets left):

The new show will be titled “Stairway to heaven”: [WayBackAdest Musica on Twitter: “Op weg naar Frankfurt 🇩🇪 voor The (Last) Composer. Wat een super mooie herinneringen aan dit programma. 👊6️⃣ Nog één keertje genieten vanavond! Next Year? 👉 Stairway To Heaven! 💪💂🏻‍♀️🎸🥁🎺 #TheLastComposer #ComposerDay #makehistory #adestsound #RvO #SvO #July30 #Kerkrade… “

Stratix BreedbandAtlas | Bekijk de consumentenbreedband dekking op uw locatie

[WayBack] BreedbandAtlas | Bekijk de consumentenbreedband dekking op uw locatie:

De BreedbandAtlas toont u actuele informatie over de dekking van consumentenbreedband in Nederland – zowel het type verbinding als de snelheid.

This is for consumer broadband connections, but for many businesses that is good enough (especially since players like xs4all and HeldenVanNu offer business plans like subnets, PIN-payment-over-IP).

Twitter doesn’t allow certain characters in your profile, but doesn’t tell which ones it dislikes

Posted by jpluimers on 2018/11/09

“Bio can’t include ‘invalid characters'”

Oh well: some profile characters give you a “Bio can’t include ‘invalid characters'” error.

This is forbidden:

Makes things work in .NET, Win32, x64, C#, SQL, Visual Studio and Delphi. Married to a cancer survivor. Responsible for brother with IQ<50. @AdestMusica member.

But this is allowed:

Makes things work in .NET, Win32, x64, C#, SQL, Visual Studio and Delphi. Married to a cancer survivor. Responsible for brother with IQᐸ50. @AdestMusica member.

I solved it thanks to these links:

I’m not the only one bumping into this; you can not put imperial height either: [WayBackeve peyser on Twitter: “WHY WONT TWITTER LET ME PUT MY HEIGHT IN MY BIO I SMELL A CONSPIRACY https://t.co/4CCNgNLTFu”

I tested ‘ and ” so they are not invalid any more.

Micro SD Cards for Development Boards – Classes, Tools, Benchmarks, Reliability, and Tips & Tricks

Posted by jpluimers on 2018/11/09

Last year I bumped into a great article about the state of the art on [WayBackMicro SD Cards for Development Boards – Classes, Tools, Benchmarks, Reliability, and Tips & Tricks.

I wonder what has changed by now.

Some references from the above article:

Load testing a web server on Windows using the ApacheBench benchmark tool from Apache

Posted by jpluimers on 2018/11/08

Based on:

  1. Download the most recent x64 Apache binaries for Windows from [WayBackApache VC15 binaries and modules download (at the time of writing: https://www.apachelounge.com/download/VC15/binaries/httpd-2.4.34-win64-VC15.zip )
  2. Extract recursively to D:\bin
  3. Run the UltrawareController locally
  4. Run D:\bin\httpd-2.4.34-win64-VC15\Apache24\bin\ab.exe -n 1000 -c 10 http://localhost:8000/foo

This will run the ab Apache benchmark tool with 1000 connections using 10 threads all doing the same http GET request at http://localhost:8000/foo

If you want to test TLS (https) connections, then you need to use the abs tool in the same directory as the ab tool supports http-only (when you still try, you get the message SSL not compiled in; no https support as explained in [WayBack] Add https support to Apache Bench on Windows – Stack Overflow).

Download location via [WayBack] windows – Is there any link to download ab Apache benchmark – Stack Overflow:

There are many more command-line parameters documented at [WayBack] ab – Apache HTTP server benchmarking tool – Apache HTTP Server Version 2.4, this is the summary:

Relay Switch Circuit and Relay Switching Circuit

Posted by jpluimers on 2018/11/08

Via yesterdays post on a bench power supply fabricated from an ATX power supply, I found this very interesting set of relay switching circuits:
