C++ What’s in a class?

http://www.gotw.ca/publications/mill02.htm Herb Sutter, 1998

With that example in mind, I'll propose the Interface Principle:

The Interface Principle
For a class X, all functions, including free functions, that both
   (a) "mention" X, and
   (b) are "supplied with" X
are logically part of X, because they form part of the interface of X.

Science* is clever

http://githubengineering.com/move-fast/ – Ruby library ‘Scientist’ from GitHub: run new code in production parallel to existing code it’s meant to replace; compare the results; user always gets the result of the existing code; devs see the deviations that would occur in a production environment.

9 bad programming habits we secretly love

http://www.infoworld.com/article/2992566/application-development/9-bad-programming-habits-we-secretly-love.html

Yes, we've all violated any number of the cardinal rules of programming, the ones that everyone agrees are bad. And we secretly liked it.

[…]

To make matters more complex, sometimes it's better to break the rules. (Shhhh!) The code comes out cleaner. It may even be faster and simpler. The rules are usually a bit too broad, and an artful programmer can improve the code by breaking them. Don’t tell your boss, but sometimes it makes sense to code your own way.

What follows is a list of nine rules that some may consider unimpeachable, but many of us break often, with both success and pleasure.

Open Live Writer

Zum Schreiben von Blog Posts war Windows Live Writer top. Jetzt hat Microsoft losgelassen und ihn frei gegeben, mit Quellcode! So geht auch Blogger wieder damit.

Den Code werde ich mir auch mal anschauen: https://github.com/OpenLiveWriter/OpenLiveWriter

When a Hippo runs a company

http://www.forbes.com/sites/derosetichy/2013/04/15/what-happens-when-a-hippo-runs-your-company

Leaders like Johnson have a special name at Amazon: they’re called HiPPOs, which stands for “highest paid person’s opinion.” HiPPOs are leaders who are so self-assured that they need neither other’s ideas nor data to affirm the correctness of their instinctual beliefs. Relying on their experience and smarts, they are quick to shoot down contradictory positions and dismissive of underling’s input.

Unicode in C++

Design for clarity

 

Essential complexity

• What is needed to defeat to solve the problem
• Try to find the simplest solution

Accidental complexity

• introduced by the expressions of the solution
• Minimize it by using C++ well

Don’t over-abstract

• Base generalizations on concrete solutions

Hide complexity

• Good interfaces are essential

Dependency Management For Binaries

Am besten sprach-übergreifend und “on premises”.

Sprachspezifisch etabliert:

• Java: Ant+Ivy, Maven, Gradle
• PHP: Composer
• Python: Pip
• Ruby: Gems
• Node.js: npm, bower?
• Javascript / CSS: bower
• R: CRAN
• Perl: CPAN

Sprachspezifisch , entwickelt sich gerade:

• .NET: Nuget
• C++: Biicode (ohne on premises), CPM

Kandidaten für sprachübergreifende Lösungen:

• Ivy (Commandline) mit eigenen Datei-Repositories oder expliziten Server-Produkten wie Artifactory oder Nexus
• Nuget mit CoApp 
• Npm mit privatem Repository (node-reggie)

Git Server

Git selbst macht keine Aussage zu Listen oder Verzeichnissen von Repositories, das muss man extern organisieren. Wie geht das in hübsch, z.B. Richtung GitHub, auf einem eigenem Server?

Kostenlos

• GitLab Community Edition
• Gerrit primär für Codereviews, kann aber mehr
• GitBlit basiert auf Java
• Gogs Go Git Service
• GitList braucht nur PHP, Source auf GitHub
• Luna verwendet Scala und MongoDB

Kostenpflichtig

• GitHub Enterprise
• Gitlab Enterprise Edition
• Bitbucket Server
• Jetbrains Upsource
• Team Foundation Server
• RhodeCode (bis 25 Leute kostenlos)

Using Time Blocks to manage productivity

http://blog.fogcreek.com/using-timeblocks-to-increase-maker-efficiency-tech-talk/

The way TimeBlock works is this: we divide a week into 10 blocks. […]
When we get a project, we divide it into TimeBlocks. […]
a task can’t be longer than two TimeBlocks, so if you have a task that takes a week, you have to write 10 different, or five different time blocks for it. […]
We frame it like if I had to do the same task this week, what would I do differently, because we have to learn from our mistakes.

PowerShell ISE mit ByPass

Zum Starten von PowerShell Skripten im ISE im ByPass-Modus die ISE wie folgt starten (im Startmenü eingeben):

powershell -executionpolicy bypass ise

Der Fehler “File XYZ.ps1 cannot be loaded because the execution of scripts is disabled on this system.” kommt dann nicht mehr.

Siehe auch http://blogs.technet.com/b/heyscriptingguy/archive/2015/03/02/write-and-run-powershell-script-without-scripting.aspx und https://blog.netspi.com/15-ways-to-bypass-the-powershell-execution-policy/

(Nachtrag: Als ordentliche generische Skriptingsprache ist PS kaum zu gebrauchen. War wohl auch nicht so gedacht. Dennoch heißt die Kolumne bei MS dazu “Hey, Scripting Guy”? Hmm. Bleibt deutlich hinter meinen Erwartungen zurück.)
