Leichtgewichtige Alternative zu RVM und rbenv

nick@klumpp.net (Nikolaus Klumpp) — Sat, 19 Nov 2011 20:02:00 +0100

Neulich noch hatte Paul über RVM geschrieben, gemeinsam mit dem vergleichsweise leichten rbenv eines der beiden bekannten Tools, um seine Ruby-Installationen zu verwalten.

Nun hat Hendrik Mans eine leichtgewichtige Alternative entwickelt, die durchaus einen Blick wert ist: Statt auch noch Kaffee zu kochen macht das System nur eines - ordentlich die aktive Rubyversion zu wechseln. Und darüber hinaus hat das Ding einfach einen knuffigen Namen: rbfu.

Gentoo Linux and Ruby..

Gentoo Linux and Ruby are not working out well.

Some Gentoo Maintainers obviously think it's wise to have a lot of Ruby Gems in their own Portage tree or in the Portage overlay "ruby". Why would someone want a packaging-system on top of a packaging-system?

It gives dependency hell and not-up-to-date packages. I can't install ruby 1.9.2 decently by just "emerge ruby". What the heck? Ruby 1.9.x is out since ages.

This got on my nerves - so deinstalled everything ruby from the gentoo system and used "RVM" instead.

Unlike Gentoo Portage concerning ruby, RVM just does what it says it will! Give it a try! It easily prevents every typical gentoo package problem with ruby.

So, installing RVM and ruby afterwards is as easy as:

bash < <(curl -s https://rvm.beginrescueend.com/install/rvm)
cd ~/.rvm/bin
./rvm install ruby-1.9.2

Have fun

Windows Server 2008 R2 Foundation von HP..

paul@klumpp.net (Paul-Dieter Klumpp) — Mon, 05 Sep 2011 22:33:28 +0200

... habe ich gekauft.

Und auf einmal heißt es bei der Installation, es habe keine HP Plattform gefunden und könne deswegen nicht installiert werden. Stimmt. Ich habe hier keinen HP-Server, sondern eine virtuelle Maschine unter VirtualBox.

Da muss ich meiner gekauften Software wohl auf die Sprünge helfen. Ich betone das Wort "gekauft". Sie befindet sich in meinem Besitz und ich will sie nutzen. Was soll diese "verbiosdongelung" auf HP-Hardware? Klar, die Intension von HP ist klar. Aber die ist in Deutschland wahrscheinlich nicht rechtens.

Gut, ich will "Windows Server 2008 R2 Foundation von Hewlett Packard" (auf deutsch) glücklicherweise in einer Virtualbox VM installieren.

Wie löse ich das Problem?

Nach einiger Recherche finde ich heraus, dass HP scheinbar nach einem HP-BIOS sucht, bevor sich Windows installieren lässt.

VBoxManage setextradata "VM Name" "VBoxInternal/Devices/pcbios/0/Config/DmiBIOSVendor" "HP"
VBoxManage setextradata "VM Name" "VBoxInternal/Devices/pcbios/0/Config/DmiSystemVendor" "HP"

Und jetzt kann ich endlich Windows Server 2008 R2 Foundation unter VirtualBox installieren. Yay!

Hier gibt's eine Liste der möglichen BIOS-Konfigurationen für VirtualBox:

Does Sony cripple original Dual Shock 3 Controllers with their latest firmware 3.56?

paul@klumpp.net (Paul-Dieter Klumpp) — Sun, 13 Feb 2011 14:43:33 +0100

I recently installed the original firmware 3.56 when it asked to and suddenly two of my three Dual Sock 3 (DS3) controllers didn't work anymore. They only work when plugged in with the USB cable. When I disconnect them, the lights switch permanently off and not even the PS-button bring up the typical blink when the bluetooth system tries to pair with the PS3.

And then the above question came up. Does Sony cripple original Dual Shock 3 Controllers with their latest firmware (FW) 3.56? Is the bluetooth in the DS3 destroyed now? Can I ever use the controller again somewhere else? Has Sony destroyed a good that I bought?

I couldn't believe this so I went googling for hints that Sony was able to disable user hardware. And truthfully, I found that since FW 3.50 Sony disables the use of non-licensed hardware on their PS3. Well, okay, I thought, this shouldn't effect me. I have three original DS3 Sony controllers! In the beginning I had bought three DS3, vigorously watching over them being original hardware. I always really liked that Sony offers good quality of hardware.

Am I at fault? Do I really have two fake DS3 Controllers? Funny, then I own some real good fakes! They cost, feel and look exactly like the other DS3 controller that still works on my PS3. Why does it feel as if Sony destroyed something that I bought and own? Somehow they managed to destroy or kill the bluetooth function in my two DS3. As I said, the two controllers don't even blink anymore when the PS-button is pressed.

Anyhow, I feel that Sony tries to piss customers off. Not only now, but forever in the future. They don't think about the outcome of their actions. I really think, I won't buy any Sony product anymore, ever.

And I was searching the web for jailbreaks to get out of this everlasting craze of Sony. In the past, Sony seemed really keen on destroying functionality from time to time and even going further to implement "product security" over customer needs. We all remember the Sony Audio-CD rootkit.

Audio-CD rootkit, see..

About PS3-Jailbreaks, see...

When I searched more.. It is even said that the FW 3.56 allows remote code execution upon login. See...

It's over.

I'm getting myself a new media player client and blu-ray player. I guess, I'll try to revive the bluetooth in the crippled DS3 and connect them to a silent PC that I will place in my living room. Sony. Listen. I heard the PC-platform has still very good games and suits as a media player as well! ;-) I don't need the PlayStation Network.
