Changing indent and tab size in Visual Basic 2008 Express

Minor annoyance in Microsoft Visual Basic 2008 Express Edition: To change the indent and tab size in Options dialog, Text Editor Basic / Editor node, you have to highlight the number in the field, then type in a new number in the Tab Size and Indent Size text fields. You can't delete the existing value first, then type in a new one.

2-Nov-2009: In Visual C# 2008 Express Edition, in Options dialog, Text Editor / All Languages / Tabs node, you can delete the existing value first.

Hiding Facebook Application Posts

Following a tip from Steven S., I've hidden posts from friends' Facebook applications that don't interest me, resulting in a much cleaner home page. In only a month, I found that I have hidden more than a hundred (!) applications, which led me to wonder if Facebook shouldn't provide a reverse option, to only show certain applications instead.

To hide applications, I can imagine that there is a database query which has a NOT IN () clause that rapidly gets longer. In contrast, to only show selected applications would require a much shorter IN () clause that grows more slowly. From an engineering point of view, the latter solution would provide a more responsive system.

On the other hand, from a business point of view, encouraging subscribers to use applications would increase Facebook's stickiness and the number of ad presentations. If subscribers aren't notified about new applications (through their friends' application posts), they are unlikely to know about these applications.

Blog Comment Spam

What a pain in the nether regions when spammers decide to use your blog as a vehicle for their crap advertisements. My blogs are moderated, so I see every comment before they are posted. I only twigged that my blog was being spammed when I saw the same comment twice for different postings on the same day (that spammer was enthusiastic). It seems (naïve, perhaps) that any comment with a URL, either in plain view or in an HTML <a> tag, is likely to be spam comment, and showed be examined closely.

Suggestion to Blogger team: include a option to mark a comment as spam, just like Gmail, and use the crowd to identify spam comments.
