Installing postman on linux


Server side rendering with phpv8/v8js on Ubuntu requires phpv8/v8js. Here is how to install the latest (at the time of writing) with php7.1.

Add the latest ppa from this guy:

Update the sources:

Install libv8:

Install and compile v8js

Optionally remove the files from the install from /tmp.

After this the SSR of the example vuejs app should work.

__dirname resolving to root of disk… /

Building an electron app you will find most of the examples refer to loading with something like:

The problem is, if you build with webpack.. then __dirname will actually resolve to the root of the disk.

To resolve this there is a simple hack/fix:

In your webpack config, add these two flags as false and things will start working.

This guy made a nice tutorial on electron with the code here, a perfect starting point if you’ve just arrived at electron

Install the dependencies to your system and app:

Ubuntu/Linux Mint Open Office

I grew up with Windows and thus MS Office… As MS introduced the Ribbon feature, IMO things went downhill. The program got overly complex and a drain on resources, as such I came upon OpenOffice… great! An open source alternative to MS Office and it worked nicely.

Then a some years back, I started messing around with Dual Booting my machine, Windows on one side and Ubuntu on the other. But with Ubuntu came LibreOffice, which to this day just does not work cleanly and smoothly as OpenOffice does.

These days, triggered by the ultimate in shady operating systems, Windows 10, I no longer dual boot and instead only use Linux. As a developer I rarely need to use Office, so up until now I have put up with inadequacies of LibreOffice… but today when I actually had to write a document from scratch, enough was enough.

Installing OpenOffice on Linux:

  1. Remove LibreOffice:
  2. Clean up:
  3. Download the latest DEB from
  4. Untar the compressed file either via cli or right cliking on the tar and selecting ‘Extract here’
  5. Open a command line in the extracted folder
  6. Change dir to DEBS
  7. Install all the program files:
  8. Install all the desktop icons for OpenOffice:
  9. Done.


Apache files as not www-data

There used to be a pretty cool mod for apache that allowed it to run certain vhosts as someone other than www-data.

Unfortunately this mod has not been kept up to date and doesn’t work reliably on newer versions of Apache2. As such you are left with a dilema, either act as apache or add apache and yourself to a group who has rights to the files.

For a dev server the better option IMO is to allow devs to ssh in as apache and thus nothing else is required. Each dev can sync their files and everything just works nicely. The reason for this is the usual suspect, Windows. Although there is Cygwin which gives linux toolbox to Windows users, there is still no way around syncing between Linux and Windows and the permissions being correct. Windows and *nix file systems are just fundamentally different. Don’t believe me, try it out for yourself, either:

  1. Rsync a fileset from a linux server to a windows desktop. Now try work on them or sync them back or even try commit the changes to git.. no joy.
  2. Rsync a  fileset from a windows desktop to a linux server.. it is basically not possible yet to retain all the file permissions. Doesn’t matter which flags you add.

Back to the topic

NB: To see users and groups see this post: previous post

Create a new usergroup webdev and add the www-data user to it and then any other users you need in this group.

At this point you have a group apache and you can both write within it. Now in the folder with the files you want to work on and apache to server you need to apply a default group:

Next we can verify:


Last thing to do is to make sure, the group webdev has rwx rights on the files

Restore a destroyed USB drive

Please note: this deletes all data on the target device and requires a real OS (so no Macs or Windows 😉 ).

I enjoy trying out new Linux distrobutions from time to time, occasionally I destroy the odd USB stick as my knowledge on partition tables is not where I would like it to be. I found a series of commands that will restore a USB stick to its former glory (even when gparted or any other program says it’s basically bin worthy)

Install prerequisite:

Assuming the target USB is at /dev/sdb

(please check first with lsblk or gnome-disks or sudo fdisk -l and be sure you know what you are formatting)

Make sure the device has no mounted filesystem and unmount it if necessary, for example:

Destroy existing partition table:

Create new GPT:

Format as FAT32:

Check it:

Should output something like:

That’s it, your stick should be clean.

Multipart form breaks nodejs express expected format

Multi-part forms usually break express as the expected body is not present.. This is also true for a JS app posting to Node if the JS app builds a FormData object:

The above npm package fixes this. It acts as a middleware to auto format incoming requests into the nice body and file format you are expecting. In your press middleware loader add the following:


Mount HDD Linux and automount with fstab

1 – Check the drive is visible to the os

Which should spit out something like this:


instead of using fdisk you could also use

if you cannot see your drive, or you don’t have a parition yet see here

2 – Create a mount point

A mount point is basically an empty folder, typically this is in either /media or /mnt on linux systems. So choose one and create a sub-directory:

3 – Auto-mount the drive with fstab

To mount the drive reliably you should mount via the UUID, this is specific to the partition.

This will output a list of UUID’s to screen, based on the output from fdisk above you should be able to recognise which line belongs to which drive.

Now add a new new entry to /etc/fstab:

4 – Mount all from fstab

That’s it. You should now be able to see the contents of your drive in you mount point. A system reboot will auto-mount the drive again.

To unmount temporarily just unmount the mount point:
