Suse Linux SP2 hwinfo: braille.4.2: alva read data freezes

I ran the command hwinfo and waited a long time seeing this message

root@suselinux10sp2:~ # hwinfo

I checked the hwinfo package

root@suselinux10sp2:~ # rpm -qi hwinfo

Then I’ve updated the package hwinfo with the one on the Suse Linux 10 SP4 ISO – hwinfo-12.67-0.7.21.x86_64.rpm

root@suselinux10sp2 # rpm -U hwinfo-12.67-0.7.21.x86_64.rpm

iPod Nano previously used on a Windows computer doesn’t work on a Mac

If your iPod previously used on a Windows computer isn’t syncing with a Mac, you need to check the Disk Format on your iPod.

On iTunes, go to Devices and click on the iPod. It will display the Name, Capacity, Software Version, Serial Number and Format. The format can be PC or Macintosh and needs to be equal to the computer you’re using.

To change the Disk Format on your iPod, click on the button Restore

Share videos from your Synology DiskStation and watch them on your Android phone

Once you checked the box “Enable DLNA/UPnP media server” on your Synology DiskStation’s Control Panel it will create three folders: music, photos and video

Put your videos on the folder called video (preferred videos encoded as MPEG4 – they have the extension ended in .mp4 or .m4v)

To watch your videos on your Android phone, you should use two programs (actually, you can use just one if you use MPEG4 videos)

To browse your DLNA server, install BubbleUPnP

You can also install the MX Player, a video player that opens almost all videos available.

Open BubbleUPnP and click on Library then select your DiskStation and browse the folders that are shared. Once you find an item that you would like to play, click on it and BubbleUPnP will ask you which video player do you want to use. You can choose MX Player.

What is a QR Code?

A QR code is the evolution of the barcode. It’s a 2D barcode that can represent an internet address, text or a phone number.

To read the QR code you need an app on your phone to scan the code.

You can install i-nigma Reader.

Open the app and scan the code.

Try scanning the QR code below:

Upgrading RAM on a Mac Mini late 2010 model – Memory beeping

On the manual of a Mac Mini late 2010 model, Apple recommends using a 1066MHz DDR3 SODIMM memory to upgrade the memory.

I’ve tried using a Kingston KVR KVR1333D3S9/4G but it ended up beeping whenever I tried to put the top memory stick.

I tried using Markvision BMD34096M1333C9-1121 and it worked perfectly as you can see below

Delete all files on /opt/compaq/cpqacuxe/bld/locks to solve this problem

root@linux:/opt/compaq/cpqacuxe/bld/locks # ls

In another occasion, solved this problem by deleting file /dev/shm/sem.hpacu.appLock on a RHEL 5

root@linux:~ # ls -l /dev/shm/sem.hpacu.appLock
