JasperReports: how to reduce the size of a Group band?
Change the Band height within the Group Header.
It maybe hard a little to find the Band height. You may want to Add Band for the Group Header first, otherwise that property (resp. set of properties) is simply not there.
Background:
I had a query with "GROUP BY country, current_month". I let each country Start on a new page. Each current_month had just one element, so I expected them to get displayed in a compact manner, but the default Band height of each group made them display with rather huge gaps.

I am amazed! No USB device sticking into the computer …
4G-Systems XSBoxGO – UMTS WIFI router, battery driven
product page at 4G-Systems
My new "away from home office" Internet access equipment. Certainly a lot more lightweight than an AVM FRITZ!Box 7390 or 7270, but it may do its job.
The specific requirement was "battery driven". Outside (e.g. on a bus (yes!!!), in a customer's office, in a friend's living or sleeping room – wherever I feel tempted to do something over the Internet), I don't want to deal with a UMTS USB stick attached to the notebook on my lap, instead I want to have the device anywhere in my bag or a pocket of my clothes, helping me without attracting other people's attraction to a fancy or huge device.
It's so tiny, you can easily put it "somewhere" and forget, where you left it. For the time being I will keep it in my tiny iPod cloth pocket, so that it doesn't catch a lot of scratches. Of course, I won't necessarily use them together.

Update 2011-07-01
- Wearing it in operating in a pocket is not a good idea, it needs fresh air.
- Restarting through pressing a button does not always work, removing the battery always works.
Update 2011-08-04
I tried to connect to it via WIFI again, and the SSID did not appear.
I dug into it, and I found, that WIFI was disabled. After enabling it again, all was fine.
I have no idea, how WIFI got disabled. That makes no sense to me.

HTML "accesskey" vs. web browsers vs. platforms

Update 2011-07-01:
Ordered a used copy at Amazon.de for about € 10 (with Amazon Prime service, i.e. delivery tomorrow). Could have had that idea earlier. Better late than never. (I assume, I had ordered the e-book for USD 5 (for o'Reilly (community) "members"), when it got released.) But it's always nice to have a hard copy, isn't it? Esp. for € 10.

It appears to me, the Google Mail Talk Gadget phones home, and if its port is filtered by the firewall, you are going to wait for ages.

backpack / wheeled bag: Eagle Creek Twist 65L
Eagle Creek Twist 65L
- night sky stratus
- sunset stratus (main part in orange – not bad, but a little too loud (in German: grell))
KaDeWe sells it for EUR 240, but you can get it for little less than EUR 200.
suppliers:
in German: "Kofferrucksack"
First saw it at KaDeWe on 2011-06-22. It's the most expensive amongst the combined backpack wheeled bags, that I saw today, but also the most attractive one. The other products were around EUR 100. Of course the samsonite one has at least reasonable wheels.

removing the antenna from a WIFI access point or a mobile phone
I am actually rather sure about this issue, but just to double-check, because I don't have a safe source for this:
I saw friends' devices, whose antenna's had gotten removed, and I was rather astonished and frightened and recommended to place the antenna again, resp. to switch wifi (power) off on the device entirely.
If you remove the wifi antenna from a wifi AP or router (or the mobile phone antenna, in case it's a pluggable / turnable one), that's not good for your health, because the device improperly attempts to broadcast anyway.Is that correct?

Will somebody pls shed some light on this?

- It uses the FRITZ!Box phone book, that's great.
- It plays Internet radio, that's also great.
- It has standard AAA size rechargeable batteries, that's really great.
- It does not have a plug for an ear-phone or loudspeaker, I miss that.
- It needs the cradle to stand upright, and the sound for playing music is best, if it lies face-down or it stands upright.

cautious automatic updating of my address book from my Facebook, LinkedIn, Xing, … contacts
If I really have time enough one day (i.e. also the money to afford that time), I would love to use those APIs to collect phone numbers etc. from there and update my address book with these details. I would really like to have that. But I already see problems like this:
- some "friends" never update their details, so the details I already have are always more uptodate, then the ones they publish in the social media profiles,
so maybe I am able to integrate those details with custom labels (to signal, where they stem from), but I would not be able to automatically update my smartphone address book from that - …

Ob-La-Di Ob-La-Da
Desmond had a barrow in the market place,Memories from a time, not as much packed with personal history and experiences as today.
Molly is the singer in a band,
Desmond says to Molly,
girl I like your face
and Molly says this, as she takes him by the hand.
Ob-la-di, ob-la-da, life goes on bra.
La la how the life goes on.
…
In a couple of yours they have built a home sweet home with a couple of kis running in the yard of Desmond and Molly Jones.
From a life, when we allowed ourselves, to have dreams.
Life was a lot, lot easier then.
We didn't know how to spell "burden" and "duties" then.

how to print a PDF document together with its filename in its upper left corner?
This is only a very special case of "how to add text given on the command line to a PDF file?"
If I don't find a nice and read utility to do this,
If I don't find a nice and read utility to do this,
- I will create an image file from the PDF file,
- I will create another image file from that text string (ImageMagick, GraphicsMagic?!?),
- and I will finally overlay them (ImageMagick, GraphicsMagic?!?).
PDF Hacks' Hack# 90 describes how to "Superimpose PDF Pages"; there is also a one-liner with pdftk for that:
$ pdftk mydoc.pdf output mydoc.marked.pdf background watermark.pdf
I need to print like 200 rather similar (1-page) files, which look rather, rather similar, and I don't want to guess the filename from the contents of the page, so I prefer to print the filename on the same page as the actual contents.
Update 2011-07-04:
I am using text2pdf (a rather, rather simple tool) for this task (regard this as one logical line):
$ echo "text to be printed into the upper left corner" | /usr/local/text2pdf/text2pdf -A4 -s10 -v12 | pdftk original_file output file_with_sth_in_its_upper_left_corner background -

pdftk packs iText’s power into a standalone program. Apply a single PDF page to the background of an entire document like so:

Winter's Bone (2010)
My last night's movie at Intimes Kino Berlin.
Actually the plan was to see "Biutiful", but my date tried hard to convince me, that this would be the movie, we wanted to see right now. I wasn't convinced, but I agreed.
The movie is really, really sad, but honestly it also has its charms.
If you don't want to risk your super-good mood for your date under any circumstances, don't watch it!
