we get full refund: the Promise VTrak m500i adventure is over… don’t buy it!


Today is a great day! We just finished the packaging of the Promise VTrak m500i and it’s hard disks. And soon it’s going to get back to Promise.


As you may have noticed we had trouble with our newly bought m500i. Very serious troubles that all pointed to one source: Promise. The firmware of the m500i just isn’t capable of doing the things Promise is promising. No 3 Tbyte Volumes. No DHCP for the Management port without a complete crash of the m500i. No saved settings (the m500i lost it’s settings after a power outtage). The list goes on.



mount(ed) harddisks:



Now back to business. We await the arrival of a NetApp and an IBM storage solution. So more on that subject soon.

Weg vom Strich mit Hilfe der EU


“In Ungarn gibt es nach Schätzungen 100.000 Prostituierte. 15 von ihnen müssen dem horizontalen Gewerbe nicht mehr nachgehen – sie werden neuerdings von der EU gefördert und in einer Medienschule zu PR-Assistentinnen ausgebildet.” (Quelle: tagesschau.de [1])


Verdammt, die sollen Medienwirtschaft in Ilmenau studieren. Oder gleich AMW. Nebenjobs gäbe es genug!

more iTunes for Windows Mobile 5.0 pictures…

I made some more pictures of iTunes for Windows Mobile 5.0 that show how it looks when it’s playing songs. And some more detailed pictures of the interface itself. They tried to make it one-hand accessible which means that you can easily control iTunes for Windows Mobile 5.0 with just one hand. You literally never have to pick the pen to click on something on the touch-screen – just use your thumb.



if you press on top information pane the pane is pulled aside and the toolbar is shown:


See the “toolbar”? There it is: Shuffle, Repeat, Equalizer. The button on the left is used to pull out the toolbar and pull in the information pane


…and as we know it from the other iTunes versions…


Finally some more words on the technical aspects: It seems that it’s entirely written in some .NET language since it requires the .NET Compact Framework 2.0 to run. And that leads me to the conclusion that there will not be an iTunes for Windows Mobile for earlier Windows Mobile versions like 2003 and 2003SE.

I so far was not able to actually buy anything in the apple store – iTunes just crashed when I tried. So there’s obviously more work to do for Apple than I thought yesterday.

So what is OrigenXbox360? It’s… I don’t really know. This viral marketing is going on and on like the first season of LOST. You are told some details – at least you think they are details….and then it’s some weird bunnies and trees and…


You see: It’s strange and it’s getting worse…of course you’re as ususal recommended to comment this article to exercise you’re right of free speech.

Apple iTunes for Windows Mobile 5 spotted!!!

UPDATE: even more pictures and testing here…

I managed to get my hands on Apple iTunes for Windows Mobile 5.0. After the Motorola ROKR Apple seems to get seriously into the mobile phone business. As my sources tell there will be a special data rate for T-Mobile bundled with devices that come with iTunes (maybe we’ll see an official announcement soon).

The version I could test was iTunes for Windows Mobile 5.0 version 0.9. Although it looks pretty complete (everything (except bonjour) is in place and even podcast sync worked like a champ (see picture)) it’s not a customer ready version. I don’t know anything about the release dates or announcement dates at the moment.

Some words to the graphical user interface: Apple decided to use the well known iTunes in favor of the iPod user interface. Since the buttons and functionalities are all where I expected them it’s as easy to use as the “big” version of iTunes.

I did not have the time for an in-depth test yet but it seems that it is not limited in the way the Motorola ROKR is. Nevertheless I was not able to sync it with a PC/Mac iTunes yet since there are no drivers (and I haven’t got any) I successfully copied 1 GB of MP3/AAC files onto a SD Card and I could play it all. When I inserted the SD Card iTunes automatically searched for media files and rebuilt it’s library. After some seconds I could start listening.

It’s about 6 AM here and I had no sleep – so more after I woke up…


we all know this icon… now even on Windows Mobile.

This MDA2 is connected to the Internet over GPRS. You can see that a search in the iTunes podcast directory was successful.

Wireless Tunes… WiFiTunes… wireless music on your Windows Mobile device

The one interesting thing is that this piece of software for Windows Mobile is giving you the possibility to listen to music which is streamed to you – hopefully wireless – from your iTunes on your Mac/PC. The second interesting thing about this application is that it’s entirely written in C# (.NET Compact Framework) and the sourcecode is/will be available. How cool is that?

“WiFiTunes is a solution that enables you to stream MP3s from a computer running iTunes to your Pocket PC. Since I last posted on the product in January, the developer has modernized the look and made the software simpler in use.”

“A C# implementation of the DAAP protocol was written using AppleRecords as a reference so thanks to Chris for doing all that tedious work. Thanks also to SPAlarm for starting a fmod C# wrapper.”

The title says it all. There is a new version of Avantgo available. And this time it does work with the newly available ActiveSync 4.0.

So if you have a Windows Mobile 5 device and you’re wondering why you cannot automatically synchronize your AvantGo account then be sure you have this update installed.

protect your property: build yourself a sentry turret

A quite nice job with some very interesting features. Please notices that this is NOT a real gun – it’s an airsoft replica of a FN P90.
These guys made quite an impressive job: Their turret is completly computer controlled and finds and follows it’s targets autonomously.



“Notice the tactical LED flashlight is glowing on the left side of the turret. There is absolutely no practical reason for that.”

Beside the complete building description there is also a short movie of the Sentry Gun in action on the website:

create something big, take the hammer and make it smaller…

..Something like that must have been in the mind of the developers of “Minimo” – a Mozilla for Windows Mobile Devices (Pocket PC/Smartphones).


It all starts with the 8.5 MByte space that that application needs on the device. And then…it took about 40 seconds to “boot” the application. After that the whole device started to get sluggish. Anyway: It does display web-pages. It does not do anything else. It took about 3-5 seconds to respond to any input I made. Of course they did not use any standard-Windows-Mobile-Widgets. Instead they coded their own controls: What a great idea! ;-(

I wasn’t aware of the fact that my instant messaging chat-logs are more than 300 MBytes. I copied them onto a new machine today and was quite confused about the size of the chat-log folder… These are logs since 2000 !!! Life’s digital!

BUBBLES! BUBBLES! – the hitcounter YOU want to have.

You have a website and you feel depressed because nobody comments your stupid articles? You want at least a little bit of appreciation? The thing that could brighten up you’re world is: Netbubbles.

This little gadget “monitors” your website: Everytime a user hits your page, everytime someone “buys” or does anything valuable on your website the Netbubble will fire some it’s special-effect-bubbles or even some light effects.

It’s a visual feedback for “the webmaster that cares” (sorry Falko, I had to take it).

dear Netbubbles Company: I WANT ONE! 😉 I could test it… send me one!!!!1 (I don’t get enough appreciation (e.g. number of comments!))

back from the short break

On thursday the spontaneous idea came up to have a short break (4 days) at the beach. It was cold though – but nevertheless I love the sea (baltic sea in this particular case).

And of course there are some panoramic views ;).

Oh by the way: Who knows where this is?

Thanks to Anna for the 4 days.

to be honest…we don’t have an explanation

Who said that we are not communicative?



This is an error message a colleague got when he tried to start the Microsoft Max Beta:

“Microsoft® Codename Max is not like any other product. That’s because it’s not a product—it’s your opportunity to try an exciting new user experience from Microsoft. Today Max lets you make lists of your photos and turn them into beautiful slide shows to share with your family and friends. Tomorrow…who knows?”

he’s our worst nightmare?

If you don’t know who Eric S. Raymond is then inform youself dude! If you know already then continue reading:


So some days ago there was a little…let’s call it “incident”. Some recruiting guy – Mike Walters, CST Senior Recruiter to be precise – sent a mail to Eric S. Raymond. A mail in which he tried to recruit Eric S. Raymond as a potential contributer at Microsoft.


So, despite the fact that Eric S. Raymond tries hard to be “Craig Mundies worst nightmage” he is maybe one of the topmost active opensource maintainers in the world. That’s one guy that takes this whole opensource-thingie serious! What might Mike Walters have thought when he got Eric S. Raymonds answer:


“On the day *I* go to work for Microsoft, faint oinking sounds will be heard from far overhead, the moon will not merely turn blue but develop polkadots, and hell will freeze over so solid the brimstone will go superconductive.”


Maybe he thought: DOH! I need a new job. Actually he said mea culpa.


BTW: Eric S. Raymond DOES look a bit scary, doesn’t he?

Superhelden im Realitätscheck

Also ich gestehe gleich zu Beginn, dass ich kein Superhelden-Fan bin. Für mich gleicht da einer dem anderen, und damit auch die Verfilmungen. Ob Batman, Spiderman oder die Fantastischen Vier: Alles Spinner im schrillen Latexoutfit.


Woher kommen die?


Wir alle wissen, dass in Japan extreme Gewalt- und Sexdarstellungen Ergebnis einer traditionellen Konditionierung der Gesellschaft sind. Und bei den Amis in damaligen Zeiten der Weltwirtschaftskrise und nationalsozialisten Feindbildern das Verlangen nach einer strahlenden Identifikationsfigur groß war. Daher rühen Figuren wie Superman und Captain America her. Als prüde Figuren gedacht, passen sie aber problemlos in jede Christopher-Streetday-Parade.


Und heute?


Wenn ein Mann Strumpfhosen trägt und sich eine Maske aufsetzt, dann will er damit doch etwas ausdrücken, oder? Ich will ja nicht von Transvestiten reden, aber “männlich” ist das nicht gerade. Daher ist das Gerücht nicht neu, dass Batman, Superman und all die Anderen in Wahrheit homosexuell sind (ohne das jetzt schlecht machen zu wollen). Ein weiteres Phänomen ist die charakterliche Blassheit, die viele Superhelden ausstrahlen. Und so einer soll Führungs- und Vorbildfunktion haben? Kein Wunder, dass sich in der Realität viele Menschen lieber dafür entscheiden, Drogendealer, Temposünder oder Steuerhinterzieher zu werden, weil das cooler und nicht so spießig ist.


Superman: “Junge, hör auf zu rauchen!”
Junge: “Ach halt doch die Schnauze, du Schwuchtel!”


Die Gegenspieler…


… sind meiner Ansicht nach noch dämlicher, nicht in ihrem Aussehen, sondern in ihrem Verhalten. Warum wollen die immer die Weltherrschaft mit unfairen Mitteln erreichen und lernen nie aus ihren Fehlern? Wenn ich solche Technologien zur Verfügung hätte, wüßte ich schon legale Wege, um damit ordentlich Schotter zu machen (gerade im Land der unbegrenzten Möglichkeiten) und so doch noch die Welt ein Stück zu kontrollieren (Microsoft macht doch auch nichts Anderes…). Nebenbei kann man dann auch die Superhelden eben wegen ihren Strumpfhosen an den Pranger stellen (gerade im Land der unbegrenzten Prüdigkeit).


Parodien…


… sind wirklich klasse. In einer Al-Bundy-Folge gab es einen Jungen, der nur mit Frauen reden konnte, wenn er seinen Katzenkopf aufhatte. Oder der Ben-Stiller-Film “Mystery Men”, wo einer der Möchtegern-Helden seine außergewöhnlichen Fähigkeiten in etwa so beschrieb: ‘Wenn ich die Augen zumache, dann kann ich niemanden sehen, der mich sieht. Ich bin daher unsichtbar.’


Filme…


… über Superhelden spielen in Deutschland traditionell wenig Geld ein (mit Ausnahme von Spiderman). Warum? Man weiß eh vorher, wer gewinnt und ärgert sich über all die dämlichen Weltherrschaftspläne der Bösen, die der Held später quasi mit einem Fingerschnippen zu nichte macht. Da fragt man sich: Wozu dann der ganze Aufwand, wenn eh Nichts passiert?


Interessante Fragen über Superhelden


Wer macht eigentlich die Häuser sauber, die Spiderman mit seinen Netzen vollschießt?
Was ist mit dem staatlichen Gewaltmonopol? Schließlich verüben Superhelden Selbstjustiz.
Warum werden Menschen zu Bösewichtern, weil sie der Held nicht beschützen konnte?

strange picture resizing when you have a high-DPI display


At the moment I am working on a Dell Latitude D800 notebook which is equiped with one of those nifty 1080i widescreen displays. That means: 1920×1080 in a 15 inch TFT display.


I got the machine preconfigured – and noticed that the Internet Explorer resizes every picture – Firefox doesn’t:



You can clearly see the difference


So I searched and found the solution for the problem: It looks like someone set the DPI Settings in the Display Settings to 125% – which caused Internet Explorer to resize every picture by 25%… what a stupid behaviour…If I would like to let Windows resize anything it would be the font size… not the size of the pictures that cannot be resized without quality loss:

hurray! iTunes 5 lost my podcast subscriptions…gnaarrr!!!

“Cool a new iTunes version!” I thought and downloaded it…but after the system restart and the first start-up of the new iTunes this came up:




“this iTunes library is damaged….”

And guess what: all my podcast subscriptions are gone. Damn! What the hell do you think you’re doing Apple?!

The “Update-Mania” on the Macs I am using is quite impressive: After a fresh Panther Installation you are forced to download more than 400 Megabyte of Updates…and at the moment around 200 Megabyte of Updates for a fresh installed Tiger…

Who is complaining about the 180 Megabytes of Windows XP!?!

benchmarking the storages: iSCSI Enterprise Target (+Software RAID0)

This time we got a Software RAID0 Volume with 2 drives which made a volume size of 976784130 sectors = 476945 Megabyte. This Volume is exported with the iSCSI Enterprise Target Software for Linux.

You may ask: Why only 2 drives this time? – The answer: The guy who did the setup of the linux machine did not know how to delete the RAID5 volume he created for the previous benchmark. So there where only 2 250 Gigabyte drives left…and yes: we sometimes have a subliminal feeling that we have to hurt him.

benchmarking the storages: Promise VTrak m500i

After all strange things that we got to deal with using the Promise VTrak we made some benchmarks (which took about 10 hours each complete run).

So here are the results of the first test:

Here are the results in all their beauty:

Interface-Transferrate with a blocksize of 128 sectors at 0.0 percent of the capacity:

sequential read rate medium (unthrottled): 43570 Kilobyte/s
sequential read rate Read-Ahead (Latency 1.62 ms): 39447 Kilobyte/s
repeatedly sequential read (“coretest”): 68155 Kilobyte/s

permanent transfer rate: (blocksize: 128 sectors):

Songs for the South: Microsoft Employees for the Hurricane Katrina Relief Effort

I really quarreled with me if I should post this article. But I do it because of the great music. One more word about my thoughts: I only want to have such real-life content on this website that regards me and my adjacency. Since this website is about technology and interesting things I don’t want to deal with daily news – and catastrophes are such news I don’t want to deal with on this website.

But now go and buy this album. It’s really great – and that’s not only because it’s completely made by Musicians who are also Microsoft Employees.



“This album has been made possible by the generous donation of music from 16 artists. These 16 artists (or contributing artists) are employees of Microsoft, and will receive no compensation from the sale of this album.

In soliciting content for this compilation, there were submitted many times the number of tracks than could fit on the CD. While the artists and tracks below represent the public face of this generosity, the willingness of the music community at Microsoft to contribute was immediate and significant. Thanks go to all who submitted tracks – both those on this album, and those not.”

the evilgate structure, and 802.1X


I told you about the Linksys WRT54GS-DE router I’ve bought to put an OpenWRT on it. So what’s it all about? Why would I want to have such a firewall-detour-device. And whats a firewall-detour-device anyway?


So let’s take the following situation: You are in a network that allows you to access parts of the internet. Lets say you can access every TCP Ports 21,22,80,119,139,143 and everything above 1024 (list is incomplete!). And this network you are in blocks every UDP data transfer you would like to do. Unfortunately all the interesting things want to have UDP or at least some lower TCP ports. – What to do? That’s why you need the firewall-detour-device. It passes you unfiltered internet through the filtered network.


In our case it would look like that:



As you can see there are two ways to use the firewall-detour-device (the little linksys in the picture). By standard RJ45 ethernet and by 802.11g WLAN. The most interesting case is the WLAN-use-case. But lets’s start with the OpenVPN tunnel: The first thing you need is a machine that has unfiltered internet. You now determine on what ports you can connect through your firewall to that particular server. TCP port 80 for example…now take OpenVPN and with a few lines of configuration the server is set-up. (OpenVPN gives you the ability to connect through virtually every port either UDP or TCP – you even could tunnel through a HTTP/S proxy but that’s not a subject of this article)


The client-side has to be configured accordingly – which means installing OpenWRT on the Linksys and getting OpenVPN ipkg’ed…


The last question would be how you would secure your WLAN access to the firewall-detour-device. You have heard about WPA? In our case we implemented a 802.1X Authentication System: The authentication is done by a radius server which runs on the linksys. The client (the users notebook/desktop pc) has a certificate issued by the same CA that issued the access-points certifcate, with just some XP_EXTENSIONS in the certificate (additional OIDs). On the linksys additionally runs a daemon that changes the WPA key every 3600 seconds (configurable).


So at the end you have a certificate based authentication with a radius server combined with a WPA Implementation which changes the WPA keys in a configurable interval.


A typical OpenVPN config file looks like this:

dev tun
proto udp

# TLS parms
client
ca [ca-certificate-PEM-format]
cert [client-certificate-PEM-format]
key [client-key-PEM-format]
dh [diffie-hellmann file]

remote [the-OpenVPN-server]
pull


There are some how-to manuals available at the OpenWRT homepage – so I do not copy-paste them here. But there are some misconceptions about the things you have to do on a Windows Client to use a 802.1X WLAN:


You need the root-certificate (the same you used at the accesspoint the only difference is that it has to be in the DER format) and you need a client certificate with XP-Extensions in PKCS#12 format. When you have both you just have to double-click to import them. When you now connect the the 802.1X WLAN you are asked to approve the root-certificate. After that you’re probably asked to choose which client-certificate you would like to use – select your client certificate and voilá. You should be connected to the WLAN authenticated with 802.1X.

a lot storage space (not a Promise Storage Appliance)


So today it continues. After the dissappointing things that happened around the Promise VTrak m500i we started to put the other machines together to do some testing. Therefore we have:


Machine 1:




  • Pentium 4 (Prescott) 3 Ghz


  • 2 Gigabyte of RAM


  • onboard Promise(!) FastTrack 597 SATA


  • 4 Port Onboard SATA


  • 2×80 Gigabyte (Western Digital)


  • 3×250 Gigabyte (Western Digital)


  • 1xGigabit Ethernet (Broadcom)


  • Windows Server 2003 Enterprise Edition


Test-Setup (Machine 2 is not in this picture…)



the drives and behind the fans…LOUD!





a hot-swap fan and SATA cable close-up shot…


Machine 2:




  • Pentium 4 (Prescott) 3 Ghz


  • 2 Gigabyte of RAM


  • 2xPromise(!) FastTrack S150 TX4 SATA


  • 7×250 Gigabyte (Western Digital)


  • 1xGigabit Ethernet (Intel)


  • Linux 2.6.something


Machine 2 on top of Machine 1…



Machine 1 is destined to be the Documentation-Server running a Sharepoint Portal Server 2003. But we’ll do some testing with String Bean WinTarget 2.0 iSCSI Target Software. On Machine 2 the iSCSI Enterprise Target will provide access via iSCSI.



Our testing would be this: We setup a RAID5 on each machine and export this 500 Gigabyte Volume as an iSCSI Target Volume. We then benchmark this volume. After that we do this again with a RAID0 across the 3 drives. (so 750 Gigabyte Volume).


At the moment we only test with Windows on the client-side. We’re using h2benchw for this purpose.


Stay tuned for the results. Oh I almost forgot: The Promise VTrak m500i successfully synched a 1 Terabyte iSCSI Volume and I was able to mount and format this volume. The first test showed that about 66 Megabyte/s are possible on this RAID5 volume. The benchmark is running since about 2 hours – would take 6 more hours to complete. Of course we’ll also will test a stripe on the VTrak m500i.
