Diagrams With PlantUML and Emacs

Starting With Dia When I had to draw UML diagrams, the tool I first used was Dia – an open-sourced diagraming software. Dia is a great tool. I have not used Microsoft Visio before, so I cannot compare what short-comings it has compared to Visio. The other tool I tried was yEd. I did not feel comfortable using it, and always went back to using Dia. Couple of years ago, with a new job, I had to draw lots of…

Remember Me, Subversion

Every three months, my workplace’s network domain will prompt to change our password. And this tri-monthly exercise would affect all the other intranet sites and systems, namely Subversion (SVN). Now, this is not a major problem because the organisation uses single sign-on via LDAP or Active Directory i.e. you can access the other intanet sites or systems with the same User ID and password. But recently, I noticed SVN doesn’t remember me, even when I clicked on the “Save authentication”…

Windows Tips – Move Window Between Multiple Monitor(s)

Most of us now have additional external monitor in our workspace. Having more than one screen, which I find, makes one productive, especially when you need to reference data on another application. Using Alt Tab to switch between applications is not the best thing to do. Prior to this, to move a window between monitors, I would use the mouse and drag it to the other screen. I have been doing this for years. I see other people doing this…

FreeBSD – Install Python 3 and Pip

I am starting a Python web project, and taking this oppotunity to learn django or flask. Development work will be done in my FreeBSD VirtualBox virtual machine. Before I started, I checked if Python was already installed. And yes, it was already loaded with version 2.7.12. [alvinsim@freebsd ~]$ which python /usr/local/bin/python [alvinsim@freebsd ~]$ python –version Python 2.7.12 [alvinsim@freebsd ~]$ But, I wanted to develop using Python 3. So, I searched if there was a port for it. [alvinsim@freebsd ~]$ psearch…

From Vim To Emacs

Disclaimer: This is not a “Vim vs Emacs” type of blog post. I wrote this to share my thoughts of using both of them. Vim Vi or vim (Vi IMproved) is a text editor. It is installed on almost all of the *nix systems. You can choose to use it with the GUI, or, use it in the terminal or command prompt. I started using vim at around 2006/07. This was at one of my previous jobs where the servers…

Automate It!

Image Credit – Eugen Stoll (Creative Commons License – CC BY-NC 2.0) Machines are wonderful. They help us to be productive by doing the things we don’t want to do or can’t do, whilst we can focus on other important things. Yes, I am LAZY! I write scripts or let services, like IFTTT (If-This-Then-That), to do things for me. This is how I automate some of my daily routines. 1. Script to update source code from repository, build and deploy…

Things I Do After I Install Windows

1. Connect to a (trusted) network After the Windows installation completes successfully, I’d connect it to the Internet. This is so that I can update Windows with the latest security patches, and download the necessary applications. 2. Windows Update It is always important to always keep your Windows (or any other OS you use) up-to-date with the latest security patches and updates. 3. Check Windows Settings For Windows prior to Windows 10, I would configure Windows Update to notify only…

Hello

I used to blog at my wordpress site. But now I have decided to merge both my website and blog since I already have my domain name and hosting. Unfortunately, this was something I had put off for a very long time. What I will be blogging about? Hacks, things which inspires me and passionate about – coding/scripting, software development/engineering, tech, art, music, my kids. How-to articles especially for my own reference. My doodles (maybe). Why blogging? To share things I’ve learned to…
