Creating a blog with Hugo and Cloudflare Pages

Wed, 19 Mar 2025 00:00:00 +0000

In this guide I’ll go through the steps required to create a Hugo blog hosted on Cloudflare.

Hello world, again!

Mon, 24 Feb 2025 00:00:00 +0000

Well I guess it’s that time of the decade when I rebuild my blog again. 😁

I wasn’t very active on the last attempt but I’ll try to be more consistent this time with posting here. I rebuilt the site on Hugo and Cloudflare Pages with GitHub integration. The content is written in Obsidian. I might do a more detailed post on the setup later.

Welcome!

Combining result strings in SQL Server

Mon, 09 Nov 2015 00:00:00 +0000

This is just a quick tip on combining (aggregating) result strings in SQL Server. Sometimes it’s useful to add multivalued columns to results (or CSV files) but it’s not all that simple.

For combining results of a JOIN to a single column you can use the STUFF function. Credit for this one goes to Devart.

SELECT
      m.maskid,
      m.maskname,
      m.schoolid,
      s.schoolname,
      maskdetail = STUFF((
            SELECT ',' + md.maskdetail
            FROM dbo.maskdetails md
            WHERE m.maskid = md.maskid
            FOR XML PATH(''), TYPE
        ).value('.', 'NVARCHAR(MAX)'), 1, 1, ''
      )
FROM dbo.tblmask m
JOIN dbo.school s ON s.ID = m.schoolid
ORDER BY m.maskname

This will produce a nice column with a value like “value1, value2, value9”.

Fixing misplaced SQL Server database files

Thu, 08 Oct 2015 00:00:00 +0000

Recently I was moving a SQL Server model database log file to another disk. I made an ALTER DATABASE [model] MODIFY FILE... command a bit too fast and pasted the destination from a file browser window. Of course this set the log directory as the new log file (…\MSSQL\Data).

I also restarted the instance before realizing my mistake, so now it wouldn’t start. How to fix this? Well I tried renaming the data folder and then renaming the data file to the folder’s original name Data. This didn’t solve the problem.

Searching and replacing text in T-SQL

Sun, 16 Nov 2014 00:00:00 +0000

I recently started learning and using T-SQL for a database integration project I’m doing at work. T-SQL (or Transact-SQL) is Microsoft’s extension to SQL that adds some transactional programming features to it. It’s used in SQL Server.

I’m slowly getting the hang of it. Mostly I’ve stumbled with the fact that it’s not quite a “real” programming language. So if you think of doing a foreach loop then you better think again and adjust your mindset to using SQL result sets.

Setting up this site with Pelican (old)

Sat, 25 Oct 2014 00:00:00 +0000

This is from my old blog.

I finally restarted my blog with an actual domain and a switch from Drupal to the Pelican static blog generator. The server uses Fedora 20 and is hosted by DigitalOcean. It’s a good hosting company with excellent pricing.

This post is mostly just a list of the steps required to setup this site. Just in case I might need to reinstall it at some point.

Drupal tip: Add your own fields to Solr search index

Sat, 14 Jan 2012 00:00:00 +0000

Drupal 7 is the PHP content management system that needs no introduction. But if you also want an excellent search engine to use with it then Apache Solr is the best choice. Solr builds on Lucene and adds some nice features on top of it.

There is a very good Drupal module to integrate the search engine with. It simplifies the Solr installation and adds most of the basic node fields into search index by default. But what about when you need to define your own fields?
