I encoutered some problems with my touchpad on ubuntu: While typing some text, the touchpad signalled the mouse some strange moves. Sometimes it marked parts of the text and the next key erased the highlighted text...
First idea was to edit the xorg.conf or something else, but i found a less difficult was via touchpad-indicator.
Over the last three months i read a really amazing book about quality of service techniques. Today everyone has internet access with more than 50Mbit/s, it seems like overbooking does not happen anymore and traffic priorization is no longer needed. But this is only the half of the truth: Using cloud service, video streaming, onling gaming, ... you can really fast reach the limit of your internet access bandwith.
If you are running a webpage and you decide to move to SSL protection you can encounter the following problem: Inside your webpage you are using tags like "iframe", "script" or "link" pointing to HTTP servers. This is considered as mixed active content (mozilla):
Ten years ago after a lecture given at the Technische Universität Kaiserslautern i started this blog with this posting (about the lecture). And you can see: the link does not work anymore but the screenshot still remains after such a long time. After this post, i owned a blog, with one entry and noticed that finding topics to write about is not really easy.
After i moved to jessie (Debian 8) my laptop moved to suspend to RAM about half a minute after startup. There was no message in the logfiles and even worse the resume does not work at all... The configuration for the suspend was in here:
After upgrading Windows 8 to Windows 8.1 my wireshark freezed on every startup without showing up the main window. The only workaround was to deinstall wireshark including wincap and installing it again. But after the nex reboot, it freezed again.
After searching around i found the following fix, with cured this problem:
inside the registry you have to change the DWORD start in
Some time ago a vmware server did not recognize any more a data disk. This disk was formatted with vmfs v3 (enter the vmware server via ssh and type mount..). First thing i did, was creating an image of this disk, to play around without any danger of data loss.
Last week i had the opportunity to use a Windows Surface RT tablet. For several month i am using a windows 8 laptop, which is equipped with a touchscreen. So i am used to the new tiles interface and i knew at least on laptops, you have the desktop-applications and the "tiles"-applications. I was curious, how it feels to work without having "two worlds" of applications on a device... But it was for me big suprise: If you install Microsoft Office on a RT device, you get the desktop back:
After knowing, that running a linux inside Hyper-V is only working with the "legacy" network adapter (look here), i was trying to build a kernel with the drivers (Microsoft has added the drivers into the Linux kernel versions >2.6.32). There is one nice tutorial out there:
In my last posting i explained how to configure a vEthernet adapter to get connectivity to the internet. But there was one "problem": You had to provide one seperate IP for each virtual host, you want to connect to the internet. But there is a solution (NAT) for this problem and it is easy to configure this with Hyper-V on Windows: [If you have not configured the "brigde"-solution i explained the last posting, then skip step 1 and start with step number 2]
First thing you have to do after enabling Hyper-V is to set up your network for your virtual machines. This is not so easy, because some things do not work... So let's start: Open the Virtual Switch Manager
After loosing all data on a completely discharged Nexus 7 (look here), i decided to encrypt the storage with my own password, so that i should be able to give the right pin into the "type password to decrypt storage"-question (hopefully).
Advantage: never loose my data again
Disadvantage on every bootup i have to enter my new pin....
Three months after the upgrade from Android 4.2 to 4.2.1 i got the option to update my Nexus 7 to 4.2.2. As before there is no official statement about the bugfixes or changes in this new version. The only thing is the confirmation screen the:
After switching to Windows 8 i was trying to configure the same mouse over behaviour as i am used to on my debian linux. If you just want focus follows mouse and auto-raise=true, then follow the description given here. If you want focus follows mouse and auto-raise=false, then you have to do some more work:
If you have to use HP printers on Windows 7 or 8, you can use the drivers provided by Microsoft. But if you want to change printing properties like duplex mode or pages per sheet and you select "Eigenschaften.. / Properties..."
