MacBook Pro: How to remove or install memory / successfully upgrading …
MacBook Pro: How to remove or install memory:
mine is a "MacBook Pro (17-inch, Mid 2009)"
Update 2011-08-03
The compatibility list said, I should add PC3 -8500 DDR3 1066 MHz type RAM, but that wasn't available at my Saturn Berlin Europa-Center, so instead I installed "2*4 GB 1333 MHz DDR3" (cost me EUR 100, not like EUR 140 as at Gravis), and that boots nice and still works very nice.
My "About This Mac > Memory" now says:
Funny, isn't it?!!
Now I run VirtualBox with WinXP inside, and I still feel like walking on air, not like on stones.

Your Mac contains 2 memory slots, each of which accepts a 1333 MHz DDR3 memory module.

installing WinXP in a VirtualBox on my MacBook Pro running Mac OS X Lion
VirtualBox
Q: Why do I need Windows at all?
A: for accounting software like Lexware Quicken, Lexware Financial Office.
Update 2011-07-24 11:51
I feel like somebody put my hands in chains. This WinXP installation binds all possible resources on my Mac, and this is just my favourite machine. I will have to wait for that installation to complete, then register that installation, then do all possible updates, than install Lexware Quicken (with all possible updates), than migrate its data, than install Lexware Financial Office (with all possible updates), ...
Update 2011-07-24 12:20
What shall I get in order to comfort my patience?
Rum, cachaca, beer, coffee, ...? I think, I go for coffee. Doesn't disturb the remainder of the day.
Update 2011-08-04
Lesson learned by now: virtualization eats memory. I you spend a little on extra memory, it will run smoothly. It's basically not a matter of CPU cycles, but only of enough memory. Don't hesitate too long, before getting that.

Resize from Any Edge
In previous versions of OS X, windows usually had resize handles in their lower-right corners. In Lion, those handles are gone and you can change a window’s size from any edge. To pull this trick off, just hover your cursor over the edge of a window and the cursor will change to a double-headed arrow; simply drag to resize the window.

To pull this trick off, just hover your cursor over the edge of a window and the cursor will change to a double-headed arrow; simply drag to resize the window.
NOTEIf you’re used to moving windows by grabbing an edge and dragging, that won’t work in Lion—you’ll simply resize the window. You’ll have to adjust your habits and click inside the window to drag it.
You’ll still see the occasional resize handle in programs like Microsoft Word, for example. Don’t worry: you can still resize such program windows by dragging any edge, though the resize handle works, too.

iReport vs. version control
Tried to include a JRXML string variable with "$Revision$" as initial expression. It's impossible to have such a string, as "$" is expected to start something JRXML specific like a field, a variable (itself!!), a paramater. And including a backslash "\" destroys the idea resp. the effect.
So: no RCS / CVS / subversion strings in JRXML. Alright within XML comments they work. But then: you never know for sure, what iReport does with your XML comments. With any future release they may decide to remove XML comments. Then you are pissed.

They removed the Spaces Grid for Lion, that's crappy. It must come back very soon.
For the time being "absolute positioning to a space" with the right keyboard shortcut and "threefinger swiping" up and down will help a little.

In Snow Leopard I had my "desktops" arranged in 4x4 matrix, that's gone now, and I am very sorry for that.

For running jruby I need a Java runtime system, which wasn't there by default, but "the system" was smart enough to tell me.

shell programming: "for" loops vs. "while" loops and scope of variables created within loop bodies
Variables, that you create (by assignment) within loop bodies, are well visible outside the loop body. This is valid for both kinds of loop.
CAVEAT:
If the "while" loop reads from a pipe, the "while" loop is executed within a subshell, i.e. the scope of the variables within the loop ends with the loop.
Example:
x=a
echo hello |
while read l
do
x=b
done
echo "x=$x"
What's the output of this echo?
x=a
Example:
x=a
for l in hello
do
x=b
done
echo "x=$x"
What's the output of this echo?
x=b

I like this paragraph:
Throw Away the Handwritten Notebooks
Now that you’ve learned some Puppet and implemented an automation that does something useful, I’d like to talk about what it all means in the real world. Configuration management has been around for a long time, but its nature is changing. When we used to talk about configuration management, it involved checklists and difficult to test scripts. Often the policy documents regarding these topics were where 90% of the effort landed, and even those were not well adhered to. In the new structure that modern automation provides us, the system configuration can be treated like code. We can put it in version control, write functional testing suites for it, and QA it just like application releases. Configurations can have releases that relate to application code releases in meaningful ways, and bugs are easier to identify because we have explicit records of changes. So throw away the handwritten server log, and stop making cowboy changes to production servers. There is a better way.
I hope, quoting it will not bring me in trouble.
Well, nice software, I think!
But how many sys-admins are there out there, that like and use Ruby? Not a lot, I guess.

how to export a blog hosted by Blogger.com?

Q: Is the output format ("Blogger Atom export format") usable for import with the WordPress blogging software?
A: WordPress.org says yes.
I also set up an account and 2 free blogs at WordPress.com; assigning a custom DNS name costs USD 12 per year and blog. That's more money than with blogger.com (i.e. Google), but it's at least an working exit strategy.

I actually preferred, if my telephone system wouldn't tell me that. Why don't they have such an option? I would even love it, if my telephone system would tell callers without caller ID, to call again later with caller ID and that calling me without caller ID is (technically) unacceptable.

Time was simply ripe for this decision. I never seriously needed TextMate before, but as for GNU emacs Mac OS X is not really the main platform, occasionally you reach points, where you prefer more perfection, and at least on OS X TextMate is a reliable and also feature rich text editor.

Skype and concurrent logins with multiple
I love using Skype IM from within Adium. As "everybody" knows, that needs the Skype utility to run itself in the background, and just with Skype itself you can only have exactly one login on a "Desktop" (Desktop session per computer). So if you want to be available for your friends and family throughout your awake time (i.e. also at work) with one Skype ID, you must also allow business contacts to make use of exactly this Skype ID. But then business contacts will also attempt to contact you during off-office hours, and you will have uncomfortable situations during evenings and weekends, if you are not able to serve them as requested.
So Skype / Microsoft are kindly asked to support such concurrent logins. You can have concurrent MSN / XMPP / … logins, so why not concurrent Skype logins?
