Solved: Very slow speed on SSD |VMware Communities (via “Building a lab with ESXI and Vagrant – DarthSidious”)

Posted by jpluimers on 2021/05/11

Via [WayBack] Building a lab with ESXI and Vagrant – DarthSidious while researching the possibility of running Vagrant (software) – Wikipedia on VMware ESXi – Wikipedia for building and distributing development environments:

[WayBack] Solved: Very slow speed on SSD |VMware Communities “solution” that seems to work for ESXi 6.5 and 6.7:

ESXi 6.5 includes a new native driver (vmw_ahci) for SATA AHCI controllers, but that introduces performance problems with a lot of controllers and/or disks.

Try to disable the native driver and revert to the older sata-ahci driver by running

esxcli system module set --enabled=false --module=vmw_ahci

in an ESXi shell.

Reboot the host to make the change effective.

which solves it for some who now get much faster results:

Your suggestion worked for me, now i am getting avg speed 250Mbps from SATA III SSD .

Hope will get the full I/Ops from SSD.

However:

One issue I still have is that my 4 port Syba PCIe controller card now vanishes after disabling vmw_ahci and I am restricted to using the SATA ports on the motherboard.

and you need backups:

WARNING: Doing this at least for me erases all the VMs on the aforementioned drive. Migrate as needed.

There was no response for a more permanent fix:

What is the permanent fix for this issue, should we expect a corrected native driver from VMware, or will this require a firmware upgrade on the part of the drive vendors?

and there seem to be other bottle-necks:

tried the command on a 6.7.

Deploying an OVA and I am getting 22.82….

I have a Samsung 860 EVO mSATA 1Tb SSD.

i re-enabled it, I got max 11.81.

Kind of crappy either way. Not SSD speeds IMO.

Why a study with only 7 respondents can be good – from Dutch paper “De Volkskrant”

Posted by jpluimers on 2021/01/07

[Archive.is] Waarom een onderzoek met maar 7 respondenten toch goed kan zijn | De Volkskrant: Denkfouten in het hedendaags ontwerp gefileerd door innovatie-expert (en cabaretier) Jasper van Kuijk. Deze week: gebruikstest.

Google translated in English.

TL;DR

Quantitative studies often require large numbers of respondents, but quantitative studies can be done with a very small group.

While quantitative studies often will get you just one result (I rate this application a 7 out of 10, or with this A/B change, click through increases by 5%), qualitative studies will get you much more specific comments like “the main menu is cluttered”, or “the design is slick” (translated from the Image in the article).

Extensive research was done for a 2003 published paper [Archive.is] Beyond the five-user assumption: Benefits of increased sample sizes in usability testing which you can read as PDF [WayBack].

Some links on assembling a proper Katalon .gitignore file

Posted by jpluimers on 2020/10/29

I used these links to find out what entries a Katalon .gitignore file should contain:

Combining the above, the .gitignore file needs to at least contain:

/.classpath
/.project
/.settings
bin/lib/
Libs/
/bin
/Libs
.settings
.classpath
settings/internal
/.svn
/bin/lib/Temp*.class
Reports/
.project
/libs/Temp*.groovy
bin/lib/
bin/keyword/

(funny that .svn should be in a .gitignore file and that various combinations of casing are used)

Enable your device for development – UWP app developer | Microsoft Docs

Posted by jpluimers on 2020/10/20

From [WayBack] Enable your device for development – UWP app developer | Microsoft Docs:

Run these as administrator on the command prompt to:

Enable Sideloading

reg add "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\AppModelUnlock" /t REG_DWORD /f /v "AllowAllTrustedApps" /d "1"

Enable Developer Mode

reg add "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\AppModelUnlock" /t REG_DWORD /f /v "AllowDevelopmentWithoutDevLicense" /d "1"

Needed for WinAppDriver to test applications from Selenium or Katalon

When you run WinAppDriver without it, you get this:

C:\Users>"C:\Program Files (x86)\Windows Application Driver\WinAppDriver.exe"
Failed to initialize: 0x80004005
Despite WinAppDriver running fine as non-administrative user, the reason was given that it requires administrative privileges: [WayBack] Why does WinAppDriver.exe require developer mode? · Issue #165 · Microsoft/WinAppDriver · GitHub.

SetCapabilities name parameters and values

Various searches for what to pass as parameters to SetCapabilities failed, but the list is right at the README, but without any mention SetCapabilities, so search engines miss it with for instance “SetCapabilities” “WinAppDriver” – Google Search that only returned these links:

Supported Capabilities

Below are the capabilities that can be used to create Windows Application Driver session.

Capabilities Descriptions Example
app Application identifier or executable full path Microsoft.MicrosoftEdge_8wekyb3d8bbwe!MicrosoftEdge
appArguments Application launch arguments https://github.com/Microsoft/WinAppDriver
appTopLevelWindow Existing application top level window to attach to 0xB822E2
appWorkingDir Application working directory (Classic apps only) C:\Temp
platformName Target platform name Windows
platformVersion Target platform version 1.0

The Myth of Advanced TDD

Posted by jpluimers on 2019/10/02

[WayBack] The Myth of Advanced TDD

People frequently ask me for “advanced TDD”. I have good news and bad news.

TL;DR:

if you think you need to to “advanced TDD”, then you don’t do TDD.

If TDD hurts, then you need to improve your design or code. It’s like going to the gym: it’s not the exercise that causes the hurt, but the lack of physical condition.
