If the website is to be redesigned or changed at a later date, it makes sense to do this work in a STAGE or TEST environment and update the LIVE website only after this work is complete. For this cloning of a WordPress website there are good and detailed blog posts, such as How to Clone a WordPress Site (Complete Guide). https://www.consulting.heikol.de/en/blog/autocomplete-ruby-on-rails-turbo/ Wed, 25 Jan 2023 13:00:00 +0000 https://www.consulting.heikol.de/en/blog/autocomplete-ruby-on-rails-turbo/ Update: February 22nd 2023 – Autocomplete for categories is now implemented Turbo provides the technology in a Ruby on Rails web application to interact more dynamically with users. How does this make it easier to enter the author of a quotation? There are many tutorials on the web for implementing Autocomplete, for example the YouTube video Ruby on Rails #60 Hotwire Turbo Streams Autocomplete Search by Yaroslav Shmarov. I had a little trouble adopting what I found into my real-world web application. https://www.consulting.heikol.de/en/blog/automatisiertes-testen-mit-bilderkennung/ Sat, 26 Mar 2022 13:00:00 +0000 https://www.consulting.heikol.de/en/blog/automatisiertes-testen-mit-bilderkennung/ To explore image recognition testing in practice, an existing test case from a web application was recreated. It is about logging in, creating an author named “Hans” twice and checking if the new entries exist. Once with Eggplant and one more time with UI.Vision. At the end you can find the original test case from the Ruby on Rails framework for comparison. The Keysight commercial product Eggplant Digital Automation Intelligence provides automated testing with image recognition. https://www.consulting.heikol.de/en/blog/regular-expression-clipboard/ Sun, 03 May 2020 13:00:00 +0000 https://www.consulting.heikol.de/en/blog/regular-expression-clipboard/ In my current customer project, I write protocols almost daily, which are stored in SharePoint. In the e-mail to the participants I then link to the stored protocol. But the URL does not look very nice: https://customer42.sharepoint.com/:w:/r/sites/ABC/Technology%20Projects/Shared%20Documents/General/03%20Realization/03%20Planning/02%20Technology%20and%20Infrastructure/Workstream%20Infrastructure%20Services/IT%20Virtualization/Meetings/200430_Virtualization.docx?d=w454d19-24ac2fab6e4f1b-0a29bc5Asa26063f&csf=1&web=1&e=QIUhot When I edit the link it is a bit tiring to cut out the file name in the small Edit Hyperlink window. Can't that just be automated with a regular expression? The chrome extension “Skim the clipboard” can manipulate the clipboard with regular expressions. https://www.consulting.heikol.de/en/blog/25-jahre/ Sat, 21 Sep 2019 12:00:00 +0000 https://www.consulting.heikol.de/en/blog/25-jahre/ My 25th company anniversary in March was only celebrated by one. And it wasn’t me, it was the XING anniversary bot. The program congratulated in my XING Activity Timeline. At the beginning of the year I was deeply involved in the project and didn’t have a minute to look back on anything. There was only Работа, Работа, Работа. I have written in recent years that I have supported clients in more than 50 projects. https://www.consulting.heikol.de/en/blog/Dienstvertrag-vs-Werkvertrag-in-der-IT/ Fri, 13 Sep 2019 12:00:00 +0000 https://www.consulting.heikol.de/en/blog/Dienstvertrag-vs-Werkvertrag-in-der-IT/ In September 2019, I conducted a workshop on service contracts vs. work contracts in IT and related topics. The workshop started with an initiative talk and had discussion sessions as well as practice exercises. The presentation in German for this is: Dienstvertrag-vs-Werkvertrag-in-der-IT.pdf (Adobe PDF-Format) Dienstvertrag-vs-Werkvertrag-in-der-IT.pptx (Microsoft PowerPoint-Format) https://www.consulting.heikol.de/en/blog/project-canvas/ Fri, 22 Jun 2018 15:00:00 +0000 https://www.consulting.heikol.de/en/blog/project-canvas/ PMI BB Chapter Meeting After Design Thinking last month there was one more interesting PMI Chapter Berlin/Brandenburg meeting Yesterday evening. In Berlin’s Chauseestraße, the creative rooms of meeet Mitte provided the perfect setting for Prof. Dr. Frank Habermann and Karen Schmidt. They started with a little exercise in which they showed how bad people are in finding out facts. Everyone makes a narrated story out of given data with the so-called “quick thinking” through interpretation and prejudice. https://www.consulting.heikol.de/en/blog/visual-storytelling/ Sun, 29 Apr 2018 15:00:00 +0000 https://www.consulting.heikol.de/en/blog/visual-storytelling/ There’s a Horse Outside the Door A picture says more than a thousand words. In a project, communication is as important as the air we breathe. It is therefore an important task of the project manager to pave the way for clear and effective communication between the stakeholders. Stakeholders are all actors affected by the project. In addition to the oral votes, the written word is usually used for the exchange within the project. https://www.consulting.heikol.de/en/blog/measure-agility/ Fri, 09 Mar 2018 12:00:00 +0000 https://www.consulting.heikol.de/en/blog/measure-agility/ Agility Measurement Agile processes offer companies higher profitability, more satisfied customers and better quality in software development. The Manifesto for Agile Software Development defines four agile values and twelve principles. But how much have the teams established from these agile values and principles? How is the maturity of the implementation of the agile development process? How much have the teams achieved with the continuous improvement over the past months? People love to measure and compare things. https://www.consulting.heikol.de/en/blog/digitalocean/ Sat, 03 Feb 2018 12:00:00 +0000 https://www.consulting.heikol.de/en/blog/digitalocean/ The starting position With my static websites I have been with the hosting provider DomainFactory since May 2003, for nearly 15 years. I also had the CMS Joomla running there. And for years I wanted to change my websites to HTTPS and to use the free Let’s Encrypt certificates. But, whenever I stopped by DomainFactory Let’s Encrypt wasn’t offered (see this long German thread). Would they rather sell there own certificates? https://www.consulting.heikol.de/en/blog/scrum-sprint-retrospective/ Sat, 05 Jan 2013 12:00:00 +0000 https://www.consulting.heikol.de/en/blog/scrum-sprint-retrospective/ All team members reflect on past sprint and develop a plan for improvements on the next sprint. Questions are: What went well during the last sprint? What can we improve in the next sprint? After sprint review and before sprint planning Facilitated by Scrum Master 3h meeting / 4w sprint additional: check Definition of Done to improve quality continuously Look at people, process and tools, How can we improve the development process? https://www.consulting.heikol.de/en/blog/debug-mode/ Fri, 28 Dec 2012 12:00:00 +0000 https://www.consulting.heikol.de/en/blog/debug-mode/ This article is unfortunately not translated into English.

Am 19. April 2012 habe ich im PMI Chapter-Meeting Berlin/Brandenburg eine Live-Demo zum Einsatz von Atlassian Jira im Projektmanagement zeigen. Die Präsentation dazu ist hier: Jira-im-Projektmanagement.pdf (Adobe PDF-Format) Jira-im-Projektmanagement.pptx (Microsoft PowerPoint-Format) Verschiedene Möglichkeiten zum Einsatz von Jira für die Planung, Steuerung, Ausführung und den Abschluss von klassischen IT-Projekten wurden lebhaft diskutiert. Die Nutzung des Jira-Plugins GreenHopper für die agile Software-Entwicklung (Scrum und Kanban) wurden gezeigt und Empfehlungen aus der Praxis zum Einsatz von Jira in Projekten beendeten den Vortrag. https://www.consulting.heikol.de/en/blog/aufwandsschaetzungen/ Wed, 05 Jan 2011 12:00:00 +0000 https://www.consulting.heikol.de/en/blog/aufwandsschaetzungen/ What is the accuracy of the estimate? For cost estimates, always specify two numbers: minimum and maximum. As project planning progresses, the uncertainties become ever smaller. For example according to PMI: Project Progress Boundary Values ROM – Rough Order of Magnitude Estimate -50% … +100% Preliminary Estimate -25% … +50% Budget Estimate -10% … +25% Definitive Estimate -5% … +10% Final Estimate 0% Results from previous projects are an important input. https://www.consulting.heikol.de/en/blog/jira-for-projekt-status/ Thu, 30 Dec 2010 12:00:00 +0000 https://www.consulting.heikol.de/en/blog/jira-for-projekt-status/ This article is unfortunately not translated into English. In der Software-Entwicklung vereinfacht JIRA das Verfolgen des Projektfortschritts und erhöht die Transparenz im Team. Eine Aufgabe des Projektleiters ist es den Fortschritt der Arbeit im Projekt zu kontrollieren. Der Abschluss der Arbeitspakete und die benötigten Aufwände werden mit dem Projektplan verglichen und die Entwicklung über die Zeit analysiert. Mit dieser Analyse kann korrigierend und steuernd eingegriffen werden und es ist eine aktuelle Prognose des Liefertermins und des benötigten Aufwands auf Basis der aktuellen Daten möglich. https://www.consulting.heikol.de/en/blog/gruyere/ Thu, 11 Nov 2010 12:00:00 +0000 https://www.consulting.heikol.de/en/blog/gruyere/ The provided web application Gruyere - holey cheese - shows with own hacking and source code analysis many vulnerabilities. Google Code University exercises are to solve from attackers view. Reading source code and using the tools (for me curl and WebScarab) is like a game with the wow factor if the next security hole is found. This makes learning fun and the solved problems are easier to remember. I analyzed my own web application zitat-service. https://www.consulting.heikol.de/en/blog/leitbild/ Tue, 01 Dec 2009 12:00:00 +0000 https://www.consulting.heikol.de/en/blog/leitbild/ Sorry, the following conten isn’t translated into English yet.

Projektangebote Das Angebot von Projektbörsen ist in den letzten Jahren explodiert. Hier Bemerkungen zu denen, die ich nutze: GULP (mit Anmeldung) und den Such-Roboter (ohne Anmeldung) Der kostenlose Grundeintrag ist schon recht sinnvoll.
