How to take a screenshot on the Samsung Galaxy S4

Hello All,

Today I got my hands on the new Samsung Galaxy S4 (AT&T). I wanted to test how to take a screenshot. For sometime now I have used my rooted Galaxy S2 with CyanogenMod which allowed for me to simply press the power button and get a menu context which allowed me to take the screenshot of my choice. Now with a stock out of the box device there isn’t a menu to do this, but rest assured there is a way and best of all its simple to do.

To take a screen shot with the Samsung Galaxy S4 you simple do the following.

  1. HOLD down the POWER button and the HOME button at the same time.
  2. Now go look for your screenshot to upload or email

If look for it you can find them in the directory /Pictures/Screenshots, or simply use the Gallery app.

HOLD down the POWER button and the HOME button at the same time

 

Wait… I’m not done. I found another way to take them also. This involves using the new Palm Motion feature which allows you to wave your hand magically over the Galaxy S4 to take the shot.

You enable this setting by:

Clicking on the MENU button and select SETTINGS

On the top menu bar, selection the “My Device” tab. Then select “Motion and Gestures”

Under “Palm Motion” settings, check “Capture Screen” button is set to ON.

Get the 3ware 9650SE working with ESXi 5.x

At the office we recently built two white box, built it yourself servers (lego’s). I called them Lego’s due to the fact they are build your own types and not OEM. For each of these powerhouse systems we got 3ware 9650SE RAID controllers (3ware 9650SE-4LPML PCI Express Lanes: 4 SATA II Controller Card RAID Levels 0, 1, 5, 10, Single Disk, JBOD, KIT).

After getting ESXi 5.x installed to a USB Stick to boot from I encountered an issue where the 3ware controller was not recognized by the system. Well this could only be one thing. Drivers.

This is where installing of the controller driver fun begins.

I first navigated to the LSI website and their support page to download the drivers for these controllers. Where I was able to find drivers for VMware ESXi 5.0 update 1 driver for 9650SE/9690SA

After downloading the zip archive of the driver, I extracted and used WinSCP to upload the drivers to the /tmp directory of my ESXi 5.x hosts.

I then logged into the ESXi 5.x using SSH with Putty.

After changing my directory to /tmp I ran the following command:

esxcli software vib install -v /tmp/scsi-3w-9xxx-2.27.08.036-1OEM.500.0.0.472560.x86_64.vib

Soon after I got the following messages:

Installation Result
Message: The update completed successfully, but the system needs to be rebooted for the changes to be effective.
Reboot Required: true
VIBs Installed: LSI_bootbank_scsi-3w-9xxx_2.27.08.036-1OEM.500.0.0.472560
VIBs Removed:
VIBs Skipped:

After the install I followed the instruction to reboot and after the systems were up and running again I was able to see the controller and create my new data-stores.

Upgrading HP ProCurve firmware via USB flash drive

Today I got a replacement HP ProCurve 2910al-48G-PoE+ J9148A to replace one that had faulted in the data-center so I am taking a moment to take a little phrase from Horace “Carpe diem quam minimum credula postero” because I may not have the chance to do this another day.

The ProCurve switch has a USB port that you can use to transfer files. And while there are other ways, today I will use this method. Only because I have assigned this switch an IP and would not want to conflict with the one in production. “Oh yeah, I copied the productions configuration to this switch already”.

I grabbed the latest version (at the time of writing this post), which happens to be W_15_08_0012. Before applying the firmware I wanted to make sure I knew the version I was currently running on.

This is done by the “show version” command:

SwitchGroup-2# show version
Image stamp: /sw/code/build/sbm(t4a)
Nov 5 2009 18:02:07
W.14.38
51
Boot Image: Primary

I then plugged in my FAT32 formatted USB stick which had the image file of W_15_08_0012.swi and typed dir <enter> to see the contents of the USB stick.

I then issued the following: copy usb flash W_15_08_0012.swi primary to copy the flash image to the switch.

When the copy has completed you will need to reload the switch. I done so by issuing the following command: boot system flash primary

The switch will reboot, and in the console you will see the updates. Once completed type: show version and you will be at the new version.

 

PS3 YLOD Fix: How I did it

Hello PlayStation 3 Owner,

If you have run into this issue, I am aware of how frustrated you are. I’ve been there and just recently fixed mine and my brother’s PS3 (Fat Body). We both encountered this same issue.

Back-story on my issue: My PS3 ran into the Yellow Light of Death (YLOD) issue and after much troubleshooting; checking cables, powering down for days, trying again… I gave up and purchased a replacement rather than paying for a repair via Sony or some third party. My PS3 has been in a box for about 2 years or longer. Recently my brothers encountered this same issue and I quickly thought, perhaps I should experiment on my old system to see if I could fix it, and if I was successful, fix his also.

Now I have read that the PS3 YLOD is caused by either too much heat or extreme cold temperature causing the solder connections to get cracked. These conditions might also loosen the connections and now you have a PS3 with the YLOD issue. That said I attempted to preform the “blow dryer method”.

You will need the following YLOD Fix it Kit:

  • 1 small screw driver
  • 1 small flat head screw driver / or in my case finger nail
  • 1 blow dryer (borrow one from your mom, sister, girlfriend, or wife)
  • 1 towel or in my case a small blanket (such as the one my son uses for naps)

Now that you have your YLOD Fix it Kit follow these steps:

  1. Unplug your PS3 from the Power, Video (HDMI), USB attached devices
  2. On the left side of the PS3, you will find a little tab, lift it out to reveal the hard driver holder
  3. Unscrew the little blue screw in the center, then pull out the hard drive, depending on the model you may need to slid the hard drive hold to the side then pull it out. *note* place the hard drive, cover, and little blue screw someplace safe.
  4. Wrap the PS3 in a towel or blanket, cover the whole unit but expose the vents in the back. *note* turn the PS3 upside down during the process so that the bottom of the PS3 is facing up
  5. Using a blow driver on high heat, blow hot air into the back vents, go slowly side to side for approx. 15 minutes. 
  6. Remove the towel or blanket, you will notice that the bottom will be very hot. Allow the PS3 to remain upside down and cool for about 15, 20, 30 minuets. Don’t attempt to cool it faster by placing in the freezer, allow it to cool to room temp on its own. **note** there is a reason for this, and I’ll go into that later
  7. Once the cool down is complete, re-install your hard drive, screw and cover tab.
  8. Attach your Power, Video (HDMI),USB attached devices
  9. Turn your TV on and change to the proper input
  10. Finally we are at the moment of truth; power on your PS3. If all went well you will see the green light and the PS3 XMB will be disabled on your screen. You are now back in action.
***final note***
If this doesn’t work the first time around please attempt it again, in my case I only had to do this once for it to work, my brother did it two times and his is working once again.

Good Luck to you,
– Jermal
