Suggested January 2024 Is There Room For Ubuntu And Firefox In Smartphone Market?
While Google and Apple have been battling it out to decide who will grab the lion’s share of the smartphone market, some new guys on the block have decided to throw their hats into the ring. Users pick up the battle, arguing whether Android or iOS is the best smartphone operating system, but they aren’t the only contenders anymore, with Ubuntu and Firefox poised to enter the market. And they’re not alone. Tizen wants a piece of the action as well.
Previously Windows Phone jumped into the game with a lot of fanfare, but they really haven’t made a dent in the market controlled by Google’s Android OS and Apple’s iOS. Despite this, Ubuntu and Firefox, as well as Tizen, have recently announced plans to join the crowded smartphone and mobile operating system market.
Mozilla has been successful with its Firefox browser, competing against Google Chrome and Apple’s Safari, and now they are ready to jump into the mobile game as well. They have plans to release Firefox OS sometime this year. Ubuntu has had its own success as a desktop operating system for Linux computers, and now they, too, want to jump into the mobile OS market with Ubuntu Touch. Tizen has no immediate plans to be released in the US, but with backers such as Samsung and Sprint Nextel Corp. a member of the Tizen Association, it makes you wonder how long it will be before Tizen-enabled phones are in the States.

The burning question is, of course, what will happen in this market. What will happen to Android and Apple? Will they continue to control the mobile OS market or will they give up some of their dominance to the overcrowded market?
Android has been gaining momentum on Apple recently, but maybe the newbies coming in will hurt their trend. For a long time, the fight has been Apple vs. the other guys, and that goes all the way back to desktop computers, as well as mobile phones and tablets. With three more joining “the other guys,” does that boost Apple’s rank and take away some of Android’s share?
It’s a good guess that Apple isn’t too worried right now, despite the mess that their stocks have become with unhappy investors. It seems far more likely that Android users will fall from the ranks to try the services of the Ubuntu and Firefox OS rather than Apple users, and if Tizen is released in the US, that’s only going to complicate things even more. It will still be Apple vs. the other guys, and the other guys will be splitting that share five ways.

What Is Lvm And How To Set It Up In Ubuntu
LVM (Logical Volume Manager) is a software that allows you to manage multiple hard disk space by creating logical volumes. Using LVM you can create, grow and shrink partitions as per your needs. LVM is made up of three components: Physical Volume, Volume Group and Logical Volume. Each volume group is made up of physical volumes. You can extend or reduce a volume group by adding or removing physical volumes.
Benefits of LVM
If you have multiple hard drives, through LVM you can group all the hard drives into one large drive.
You can create and resize new partitions as needed.
You can add an extra hard disk to a current volume group to increase space.
Note: This tutorial assumes you are using Ubuntu and have three hard disks (/dev/sda, /dev/sdb and /dev/sdc).
Create Partition on /dev/sdb and /dev/sdcFirst you need two unpartitioned hard disks “/dev/sdb” and “/dev/sdc.” You need to create physical volume on this hard disk and need to create a partition on each hard disk for this.
To create a partition on “/dev/sdb”, run:
sudo
fdisk
/
dev/
sdbAnswer all the questions shown below.
Repeat the same process for /dev/sdc.
To re-read the partition table without rebooting, run the following commands:
sudo
partprobe/
dev/
sdbsudo
partprobe/
dev/
sdc Create the Physical VolumesA physical hard disk is divided into one or more physical volumes. Here we will create a single physical volume on each hard disk.
To create the physical volume on “/dev/sdb1” and “/dev/sdc1”, run
sudo
pvcreate/
dev/
sdb1/
dev/
sdc1It will output something like this.
Create the Volume GroupA combination of one or more physical volumes is called a Volume Group. You can use the vgcreate command to create a volume group from one or more physical volumes.
To create the volume group “VG1” on a physical volume (/dev/sdb1 and /dev/sdc1), run the following command:
sudo
vgcreate VG1/
dev/
sdb1/
dev/
sdc1The output is something like this.
To verify the volume group, run
sudo
vgdisplay/
dev/
VG1and its output.
Now we have a single 19.52 GB size volume group (VG1).
Creating the Logical volumeThe volume groups can be divided into logical volumes and assigned mount points. When the size of logical volumes are full, you can add required free space from the volume group.
Now create the logical volume (LV1 and LV2) of 5 GB size.
sudo
lvcreate VG1-L
+5G-n
LV1sudo
lvcreate VG1-L
+5G-n
LV2Change “VG1” to the volume group name. The -L flag specifies the size of the partition, while the -n flag specifies the name of the logical volume.
To verify the logical volume, run
sudo
lvdisplayand its output.
Finally, we have successfully created an LVM partition of 5GB.
Format and Mount the LVM Partition (LV1, LV2)To use the logical volumes, we need to format them first. We can format the LVM partition using the ext4 file-system with the following command:
sudo
chúng tôi/
dev/
VG1/
LV1sudo
chúng tôi/
dev/
VG1/
LV2Create a directory in “/mnt” for a mounting partition.
sudo
mkdir
/
mnt/
LV1-mount/
mnt/
LV2-mountMount the LVM partition by editing the “/etc/fstab” file.
sudo
nano
/
etc/
fstabAdd the following line:
/
dev/
VG1/
LV1/
mnt/
LV1-mount ext4 defaults0
0
/
dev/
VG1/
LV2/
mnt/
LV2-mount ext4 defaults0
0
For the changes to take effect without rebooting the system, run
sudo
mount
-a
To verify the mount:
sudo
df
-h
It will output something like this.
Resize Logical VolumesOne of the benefits of LVM is to extend or reduce the size of the partitions. We can resize the logical volumes on the fly without rebooting the server. We can easily extend/reduce the logical volumes using lvextend/resize2fs commands.
Extend Logical VolumeIn some situations, we need to expand the size of a low space partition. We can easily expand any partition using the lvextend command. We can extend logical volumes only if the volume group has enough free space.
To extend the logical volume LV1 from 5GB to 6GB, run
The logical volume is 6 GB, but the file system on that volume is still only 5 GB.
To make the file system use the entire 6 GB available, run
sudo
resize2fs/
dev/
VG1/
LV1The output is something like this.
Reduce Logical VolumeReducing logical volume is a more interesting part than any other part in logical volume management. Before reducing logical volume, it is good to back up the data.
You need to perform the following steps to reduce logical volumes.
First, to unmount the logical volume LV2, run
sudo
umount
/
dev/
VG1/
LV2Then check for the file-system error using the following command:
sudo
e2fsck-f
/
dev/
VG1/
LV2Next, reduce the logical volume LV2 from 5GB to 4GB by running
sudo
resize2fs-p
/
dev/
VG1/
LV2 4Gsudo
e2fsck-f
/
dev/
VG1/
LV2Mount the file-system back to the mount point.
sudo
mount
/
dev/
VG1/
LV2/
mnt/
LV2-mountCheck the new size of logical volume by running
sudo
df
-h
The output is something like this.
Delete Logical VolumeTo delete a logical volume, you need to unmount then volume before you can delete it.
To delete a logical volume LV1, run
sudo
umount
/
dev/
VG1/
LV1sudo
lvremove/
dev/
VG1/

Is Your Smartphone Overheating? This Is What You Should Know
How it all started?
I think the present wave of consumer panic started with Xiaomi Mi3. It was the perfect smartphone one could ever dream of at 13,999 when it was launched and gave Xiaomi a solid head start over other Chinese brethren, but it had one issue. The Aluminum frame heated up abnormally with what is considered day to day usage. I don’t remember anyone asking me about heating issues in a phone prior to purchase before that.
Xiaomi’s best selling Redmi 1S was no exception either. In fact, Xiaomi had to later roll out an OTA update to fix the heating. Also with the transition to 64 bit world, Qualcomm hastily made some tradeoffs and we saw chipsets like Snapdragon 810 and Snapdragon 615, adding more fuel to the fire.
Moreover, Consumers have grown a strong linking to slim smartphones, and slim profile, with metal and glass backs, combined with more densers batteries inside, can make your phone feel even hotter. Some well known cases being Gionee Elife S5.5 and Canvas Knight A350.
How much is too much? Image source – Tweakers What are causes of smartphone heating?Processor – The number one culprit these days are the chipsets as mentioned above. Smartphones with Snapdragon 615 and Snapdragon 810 are world renowned for haphazard heating (though things will improve with next gen Snapdragon 810 and 820), but these are not the only culprits.
If your battery is old and your phone has started heating up in the region around the battery rather easily, you should replace the battery.
Poor Signals – Poor cellular reception or even attempting to download apps and other stuff on a weak WiFi or Bluetooth Signal needs your smartphone to do more work and can cause excessive heating.
Extended usage – Recording videos at high resolution can heat up all phones within 10 minutes. Also extended calling say for hours can cause your phone and even your brain to heat up beyond what is considered safe.
What are long term drawbacks if my phone heats up too often?Heat is the numero uno enemy for all electronic devices. It can lead to variety of damages, but with smartphones, you should worry more about the damage to your battery rather than motherboard. If temperature raises to an alarming level, your phone will display a warning and switch off (just like laptops do).
Impact on battery – Apparently, heat is a threat to your phone battery. If the temperature is often above 40, some researchers claim that your battery will lose 15 percent of the charge within a year. In day to day usage, temperature is mostly around 35 ℃ in our experience. While that’s in theory and in practice there is no way to confirm how much damage you will incur as it largely depends on your usage. Most people upgrade their phones every couple of years and if not, a software update arrives which blows away the battery backup out the window either way.
Impact on performance – Excessive heating in chips like Snapdragon 615 and Snapdragon 810 can however lead to poor performance. If the temperature rises CPU throttles. Which means it your processor starts running at a reduced clock frequency, which slows down your phone. If temperature rises quickly, this can happen within minutes. This is the drawback that will irk you most and more often.
What should i do if my phone is uncomfortably hot way too often?Put it in safe mode – If your smartphone was running cool for sometime and has only recently started heating, put it in safe mode (press power key and long press power-off option). If it is running fine now, a rogue app is most likely the cause. Boot it again and uninstall all recently installed apps.
There is nothing much you can do on your own.
Wrap upwe have seen people paranoid about their phones heating up even when they shouldn’t. It is wiser to check reviews and ask for guidance before you purchase your next smartphone. It is a genuine concern, but still, every phone heats up today and you shouldn’t panic if temperature rises once in a while.
