gmail harmless error message when editing settings: “Your changes have not been saved. Discard changes?”

Posted by jpluimers on 2010/01/28

When you edit your gmail settings, recently you often  get this message if you move the focus away from the settings pane:

Your changes have not been saved.
Discard changes?

The odd thing is that the settings are indeed saved just before you move the focus away.

So I always wondered if the message can be really ignored, and this thread confirms the message indeed is harmless.

I do still wonder why I get this message mostly in FireFox and Internet Explorer, but almost never in Chrome :-)

Validate XML with XSD in .NET and native MSXML – big difference in string maxLength validation with newlines (samples in C# and Delphi)

Posted by jpluimers on 2010/01/19

Recently, I had an issue while validating XML with XSD: validation in .NET using the built in classes in the System.XML namespace, and validation in native Windows using the COM objects exposed by  MSXML version 6 (which incidentally ships with the .NET 3.0 framework).

Some documents validating OK in .NET did not validate well with MSXML.

I’ll show my findings below, and try to explain the difference I found, together with my conclusions.
The main conclusion is that MSXML version 6 has a bug, but I wonder why I can’t find much more information on it.

Since there is not so much ready to use for validating XML by XSD in .NET and native, I’ll include complete source code of command-line validations applications for both platforms.
.NET source code is in C#.
Native source code is in Delphi.

Delphi – HIGHCHARUNICODE directive (Delphi) – RAD Studio

Posted by jpluimers on 2010/01/18

I forgot about it, but this thread (which got wiped by Embarcadero) reminded be about the differences between these two character values.

Quoting from the first post:

c1 := #128;
c2 := chr(128);
Assert(c1 = c2);

the assertion fails, meaning that c1 <> c2.

In fact c1 = #$20AC and c2 = #$80.

Web Security: Are You Part Of The Problem? – Smashing Magazine

Posted by jpluimers on 2010/01/15

These Smashing people provide real concise info.

Note their quite though:

Disclaimer: the things we’ll talk about in this article today won’t make you a security expert, just as buying a Swiss Army knife won’t make you a locksmith or buying a whip won’t make you a lion tamer. The purpose here is to raise awareness and perhaps make some of that security mumbo-jumbo a bit more understandable to you.

5 Alternatives to Keeping a Fax Machine

Posted by jpluimers on 2010/01/14

Like Thursday Bram, I can’t remember the last time I sent a FAX.
I still have a FAX: it is a multifunctional HP Color LaserJet 2840.
It was one of my biggest mistakes, see at the end of this blog article why.

Back to faxing: unlike Tursday, I live in The Netherlands, so I’ll explain how my FAX stuff works. Read the rest of this entry »

Windows 7 has lots of ‘GodModes’ (exclusive) | Beyond Binary – CNET News

Posted by jpluimers on 2010/01/14

Some more GodModes in Windows 7.
Note that some might work in Vista too, but note that Vista-64 users have problems with the original ‘GodMode.{ED7BA470-8E54-465E-825C-99712043E01C}‘ folder name (in fact any name before the dot will work: ‘Thor.{ED7BA470-8E54-465E-825C-99712043E01C}‘ is fine too.

You can also run ‘explorer shell:::{ED7BA470-8E54-465E-825C-99712043E01C}‘ from the command-line or from a batch file (like thor.bat).

Posted by jpluimers on 2010/01/14

In todays fusion of Web 2.0 and mobile users, performance is key again.

The below article by Christian Heilmann explains the what and how of improving your website performance.

It contains references to the current tools that help you measure and improve performance.
The article also references some interesting videos, and people that lead in performance improvement.

Recommended reading!

Quote:

Even if you don’t have millions of users (yet), consider one very important thing: people are consuming the Web nowadays less with fat connections and massive computers and more with mobile phones over slow wireless and 3G connections, but they still expect the same performance. Waiting for a slow website to load on a mobile phone is doubly annoying because the user is usually already in a hurry and is paying by the byte or second. It’s 1997 all over again.
