After upgrading VMware workstation, I noticed when making backups of my VMs that they contained lots of files in the guestappscache subdirectory that have names containing GUIDs.
I’m always wary for sudden seemingly random files being created.
It might be just some kind of virus slipping through the gates targeting a specific vulnerability.
The files appear to be for Unity, and it is easy to disable Unity. (I don’t use Unity: I use VMs to separate work and keep the clutter away from my host machine’s desktop <g>).

I always forget the syntax, because different DBMS systems use different ways of doing this.
This is the SQL Server way of doing some date calculations: Read the rest of this entry »

Quite a while ago, Neil Moffat started the Delphi Basics site.
It is aimed at beginners, but since it has such a wealth of information (for instance a comprehensive list of compiler directives).
So even if you are a Delphi pro, it is worth to give Delphi Basics a look.
The cool thing: Neil originally is not even a programmer, nor a writer.
Maybe that is his strength: he learned by doing, step by step, now giving us a peak on what he learned.

Probably a few others will blog about these tweets too.
I have bolded the most important pieces:

When on the road without access to your most favourite XML editing tools, and you want to view a local XML file, you are a bit stuck.
The built-in XML viewing capabilities of Internet Explorer 6 and up give you those nice “To help protect your security, Internet Explorer has restricted this…” messages.
Disabling those messages makes your system a lot less secure, so that is not a real option.
This besides the lack for viewing UTF-16 encoded XML files in Internet Explorer (and getting the dreaded “Switch from current encoding to specified encoding not supported. Line 1, Position 40“).
So, in my toolbox is XML Viewer from MindFusion. Read the rest of this entry »

Since you do this only once per server, it is easy to forget (I do) where to specify the hostname of your ESXi server.
vm-help.com describes in Change your host’s network name how easy it is in ESXi 3.x (and also how to change the DNS information and SSL certificate).
ESXi 4.x is very, but not completely, similar Read the rest of this entry »

Brilliant and so true:
New programmers are drawn to multithreading like moths to flame, with similar results.
Edit: And this is just one example on how tiny little details can impact threading so much.

When running different SQL server versions and editions, you often want to know what a certain instance is about.
For that, SQL Server T-SQL provides [WayBack] ServerProperty.
Since I absolutely love [WayBack] sqlcmd, I extended my set of SQL Server batch files with this one showing you some of the [WayBack] ServerProperty values: Read the rest of this entry »

Recently, I had the error message “Multiple-step OLE DB operation generated errors. Check each OLE DB status value, if available. No work was done” occur to me when connecting through the “Microsoft OLE DB Provider for SQL Server”.
I got the below message (in this case in Delphi, but I have seen lots of other people having the same issue using other environments too): Read the rest of this entry »
