Iterations Mean Rapid Feedback — Agile Heretic Episode Five

Posted by jpluimers on 2018/02/08

Though sprints help maintaining some rhythm, don’t let them dumb you down:

Have you ever run for real, then run on a treadmill? Running for real means that you have a pace, hopefully sustainable, and off you go. If…

Stuff on my research list thanks to Martijn Laarman (@Mpdreamz)

Quite some time ago, I attended a great introductory elasticsearch/kibana workshop by Martijn Laarman (@Mpdreamz, github.com/Mpdreamz and SO martijn-laarman) that lead me into researching a lot of interesting new things:

Mixing x64 Outlook with x86 Delphi: never a good idea…

Posted by jpluimers on 2018/02/07

Via [WayBack] Hi all,I’m a bit stuck here with a “simple” task.Looks like Outlook 2016 doesn’t supports “MAPISendMail”, at least, if i trigger this, Thunderbird… – Attila Kovacs – Google+:

Basically only MAPISendMail works cross architecture and only if you fill all fields.

This edited [WayBack] email – MAPI Windows 7 64 bit – Stack Overflow answer by [WayBack] epotter is very insightful (thanks [WayBack] Rik van Kekem – Google+):

Calls to MAPISendMail should work without a problem.

For all other MAPI method and function calls to work in a MAPI application, the bitness (32 or 64) of the MAPI application must be the same as the bitness of the MAPI subsystem on the computer that the application is targeted to run on.

In general, a 32-bit MAPI application must not run on a 64-bit platform (64-bit Outlook on 64-bit Windows) without first being rebuilt as a 64-bit application.

For a more detailed explanation, see the MSDN page on Building MAPI Applications on 32-Bit and 64-Bit Platforms

Anti Patterns Catalog

Posted by jpluimers on 2018/02/06

Recommended for any software developer or architect: browse [Archive.is] Anti Patterns Catalog and re-read it 6-12 months later, then contemplate if you have improved.

Summary:

This catalog lists AntiPatterns in two ways:

Removing double quotes from variables in batch file creates problems with CMD environment – Stack Overflow

Posted by jpluimers on 2018/02/06

Thanks [WayBack] Mr. Rick for the answer as this is exactly the bit I needed:

Input:

set widget="a very useful item"
set widget
set widget=%widget:"=%
set widget

Output:

widget="a very useful item"
widget=a very useful item

[WayBack] Removing double quotes from variables in batch file creates problems with CMD environment – Stack Overflow

This trick is convenient in cases like this:

set LocalHostsFile="%windir%\System32\drivers\etc\hosts"
set LocalHostsTemplate="%LocalHostsFile:"=%.template"

The above replaces ALL double quotes with nothing.

If you want to smart replace (like done when de-quoting CSV), you need a bit more complex code like described in [WayBack] batch file – Remove quotes from named environment variables in Windows scripts – Stack Overflow, where you basically have two options:

  • assigning inside a for loop
  • assigning inside a subroutine

Both work because parameters used like %~x do get their quotes removed; you cannot use that syntax on plain variables.

Life Beyond Distributed Transactions – ACM Queue

Posted by jpluimers on 2018/01/31

This article focuses on how an application developer can build a successful scalable enterprise application when he or she has only a local database or transaction system available. Availability is not addressed, merely scale and correctness.

I’m re-reading [WayBack] Life Beyond Distributed Transactions – ACM Queue as it such a great article.

Via: [WayBack] Pat Helland on scaling: If you are not willing to pay the cost of distributed transactions, what options do you have and what are the costs associated with this choice – Kristian Köhntopp – Google+

Executive Summary: embrace uncertainty. It can’t be avoided.
