    This electric bus can handle a day’s worth of transit on one charge 

    The Proterra Catalyst E2 is capable of serving the full daily mileage needs of nearly every U.S. mass transit route on a single charge and offers the transit industry the first direct replacement for fossil-fueled transit vehicles. (PRNewsFoto/Proterra) Tesla topping the 300 mile per charge rating with its new 100 kWh battery was a big deal, but a new zero emission bus debuted today by Proterra has actually managed 600 miles out of a full battery in testing. In a real-world setting, Proterra’s new Catalyst E2 will probably manage somewhere between 194 and 350 miles in actual use settings – but that’s plenty according to… Read More

    New Apple iPhone to have no headphone jack. 

    Apple phone to have no headphone jack.

    Apple phone to have no headphone jack.

    The new Apple iPhone will have no headphone jack, it will instead have a set of cordless earbuds that will sit in your ear and will therefore not have an annoying cable. But it seems that they would be easy to lose down a drain. They cost $179.00, so they are quite an expensive thing to lose. It would be good to have a string tied to them so they are not lost, but then why have cordless earbuds in the first place? And there is a charger for the headphones which must be charged before you can charge the earphones. And you cannot listen to music whilst charging the phone. That is a stupid idea, that is why Samsung phones are better, and parts are cheaper to replace, I had to have a charging port replaced on a Samsung N9005 and it only cost me AU$55.00 to get a new one installed, it would cost a lot of money to have an Apple part replaced in comparison. But no being able to use headphones whilst charging your phone is the worst thing.

    This might backfire on Apple and it might not. Sure is a brave move to change their technology like this, but why are they removing a headphone port, they could just use a flat plug like the lightning connector for the charging port? And why do we not have a solar panel on the back of the phone to allow charging the device in the sun? That would work very well, then you could keep your phone charged on a windowsill. That would be a good innovation. There is one prototype phone that has this feature, it is built into the screen that allows charging the mobile phone in the open. This would be good for remote areas. I bet that you can not even use a splitter to charge the phone and listen to music at the same time.

    I guess people do not want this.

    I guess people do not want this.

    This is just a very strange idea, but Belkin have come to the rescue, there is a splitter available that allows charging whilst using earphones. This is a godsend.

    Missouri court rules against Tesla selling at its own dealerships in the state 

    MIAMI, FL - FEBRUARY 19:  People look at a Tesla Motors vehicle on the showroom floor at the Dadeland Mall on February 19, 2014 in Miami, Florida.  Tesla said today it earned $46 million in the fourth quarter on a non-adjusted basis, or 33 cents a share, causing shares in the company to jump 12 percent.  (Photo by Joe Raedle/Getty Images) Tesla continues to try to up-end the dealership system in the U.S., which generally requires that franchise-onwned dealers sell cars, vs. automakers selling directly via their own wholly owned dealerships. The latest beat in he ongoing battle comes in Missouri, where Cole County Circuit Court Judge Daniel Green decided in favor of the Missouri Automobile Dealers Association (via Autoblog)… Read More

    How to get information about your filesystems with the Linux command line. 

    The Linux command line allows a user to get good information about filesystems using the shell prompt. Here are some examples.

    Print a list of all filesystems and their sizes in megabytes.

    ubuntu ~ $ df -Hla -BMB
    Filesystem     1MB-blocks    Used Available Use% Mounted on
    sysfs                 0MB     0MB       0MB    - /sys
    proc                  0MB     0MB       0MB    - /proc
    udev                516MB     1MB     516MB   1% /dev
    devpts                0MB     0MB       0MB    - /dev/pts
    tmpfs               105MB     1MB     104MB   1% /run
    /dev/xvda1        31563MB 25670MB    4504MB  86% /
    none                  1MB     0MB       1MB   0% /sys/fs/cgroup
    none                  0MB     0MB       0MB    - /sys/fs/fuse/connections
    none                  0MB     0MB       0MB    - /sys/kernel/debug
    none                  0MB     0MB       0MB    - /sys/kernel/security
    none                  6MB     0MB       6MB   0% /run/lock
    none                521MB     0MB     521MB   0% /run/shm
    none                105MB     0MB     105MB   0% /run/user
    none                  0MB     0MB       0MB    - /sys/fs/pstore
    systemd               0MB     0MB       0MB    - /sys/fs/cgroup/systemd

    List all block devices in your Linux machine and their mountpoint.

    ubuntu ~ $ lsblk
    xvda    202:0    0  30G  0 disk
    └─xvda1 202:1    0  30G  0 part /

    The parted utility allows a superuser to list all filesystems in a Linux system.

    Just run sudo parted and then the print all command.

    sudo parted
    GNU Parted 2.3
    Using /dev/xvda
    Welcome to GNU Parted! Type 'help' to view a list of commands.
    (parted) print all
    Model: Xen Virtual Block Device (xvd)
    Disk /dev/xvda: 32.2GB
    Sector size (logical/physical): 512B/512B
    Partition Table: msdos
    Number  Start   End     Size    Type     File system  Flags
     1      8225kB  32.2GB  32.2GB  primary  ext4         boot

    The fdisk command will also list all filesystems.

    ubuntu ~ $ sudo fdisk -l
    Disk /dev/xvda: 32.2 GB, 32212254720 bytes
    255 heads, 63 sectors/track, 3916 cylinders, total 62914560 sectors
    Units = sectors of 1 * 512 = 512 bytes
    Sector size (logical/physical): 512 bytes / 512 bytes
    I/O size (minimum/optimal): 512 bytes / 512 bytes
    Disk identifier: 0x00000000
        Device Boot      Start         End      Blocks   Id  System
    /dev/xvda1   *       16065    62910539    31447237+  83  Linux

    Sfdisk is a good alternative, this will display partition sizes in megabytes.

    ubuntu ~ $ sudo sfdisk -l -uM
    Disk /dev/xvda: 3916 cylinders, 255 heads, 63 sectors/track
    Units = mebibytes of 1048576 bytes, blocks of 1024 bytes, counting from 0
       Device Boot Start   End    MiB    #blocks   Id  System
    /dev/xvda1   *     7+ 30718- 30711-  31447237+  83  Linux
    /dev/xvda2         0      -      0          0    0  Empty
    /dev/xvda3         0      -      0          0    0  Empty
    /dev/xvda4         0      -      0          0    0  Empty

    There is also a Python script, pydf, this will list all partitions on your hard drive.

    Firstly, install this script.

    sudo apt-get install pydf

    Then run this script to get an idea of how much space is left on your filesystems.

    ubuntu ~ $ pydf
    Filesystem Size Used Avail Use%                                  Mounted on
    /dev/xvda1  29G  24G 4294M 81.3 [########################......] /\

    To get the UUID of a Linux filesystem, run this command and get the UUID that matches the name, such as /dev/sda1.

    ubuntu ~ $ blkid
    /dev/xvda1: LABEL="cloudimg-rootfs" UUID="ee515a1e-7735-4529-822f-4cc9e7632cd3" TYPE="ext4"

    The output of the pydf script is the best, using a simple graph to show how much disk space is taken up. This means that it is the quickest to interpret. The output of the df -Hla -BMB command can be the hardest to interpret as it outputs so much, but I will leave it up to you which you choose to use. Linux has so many options right now it can be quite overwhelming. Just choose the option that suits you.

    Blue Apron’s “Farm Egg” makes me question everything 

    farm-egg Farm egg. It may seem as simple as just that. An egg. The food that Atkins and Paleo diets made popular once again.

    Some very useful bash shell tips. 

    The bash shell has some very useful features when using the command line. This can make using the command line much faster. For example, if you forget to type sudo before a command, this can be fixed this way.

    jason$ fdisk -l /dev/sda
    fdisk: cannot open /dev/sda: Permission denied

    Type sudo !! at the command line.

    jason$ sudo !!
    sudo fdisk -l /dev/sda
    [sudo] password for jason: 
    Disk /dev/sda: 1.8 TiB, 2000398934016 bytes, 3907029168 sectors
    Units: sectors of 1 * 512 = 512 bytes
    Sector size (logical/physical): 512 bytes / 512 bytes
    I/O size (minimum/optimal): 512 bytes / 512 bytes
    Disklabel type: dos
    Disk identifier: 0x000658b4
    Device     Boot  Start        End    Sectors  Size Id Type
    /dev/sda1  *      2048     206847     204800  100M  7 HPFS/NTFS/exFAT
    /dev/sda2       206848 3907026943 3906820096  1.8T  7 HPFS/NTFS/exFAT

    And the command will be redone with the sudo command prepended to it.

    Press ^p to retype the last command at the bash shell prompt. If you have already typed something at the prompt, it will be replaced.

    ^l will clear the terminal window.

    ^a will take the cursor back to the start of the command line.

    Press ^w to erase back one word on the command line. Use this multiple times to erase a whole sentence.

    Print information about your tty terminal interface like this.

    Printing information about the terminal.

    Printing information about the terminal.

    To erase an entire line, run this command.

    jason$ stty kill ^a

    Now ^a will erase an entire line at the bash prompt. Put this into the .bashrc and this will be available whenever you need it.

    More bash shortcuts information here.

    Have fun!
