interesting: YUMI – Multiboot USB Creator that understands both Windows and Linux

Posted by jpluimers on 2014/09/15

Ever wanted to put all your Windows installs on a bootable USB stick, but also add some Linux functionality?

It looks like YUMI can do just that.

On my research list (:

Some notes on the Samsung UE40C6800 TV, PVR, decoding the PVR recordings and SamyGO extensions

Posted by jpluimers on 2014/09/10

After having recorded quite a few broadcastings to USB from my Samsung UE40C6800 TV with the T.VALDEUC 3011.0 firmware, I wanted to copy them over to either a Windows or Linux based machine for post editing.

Then I found out the USB device had been reformatted into XFS, probably because of its Guaranteed-rate I/O.

The first post I came across (SettoreZero: XFS filesystem and Samsung LEDTVs) indicated XFS is supported under Linux, but not under Windows (it appears the latter might be true).

So I went collecting useful links on which I will start doing deeper research in a few categories.

As it looks now, most of it will probably lead to various Linux shell scripts based on SamyGO.

General info:

XFS documentation:

Limux support:

Windows support:

SamyGO (selected with this particular TV in mind):

SamyGO forum:

Linux: sudo, su and their options (via: Ask Ubuntu)

Posted by jpluimers on 2014/08/25

Applies to many Linux distros and explains a lot about sudo, su and their parameters: sudo – How to run a command as a user whose login is disabled? – Ask Ubuntu.

Linux/bash: using mutt to send a file as an email attachment (via: Stack Overflow)

Posted by jpluimers on 2014/08/21

Just in case I need this again:

None of the mutt ones worked for me. It was thinking the email address was part of the attachemnt. Had to do:

echo “This is the message body” | mutt -a “/path/to/file.to.attach” -s “subject of message” — recipient@domain.com

Thanks Alexander Bird for noticing the double-dash, rynop for the modified answer and Chris N for the original answer.

Linux: no more correct license file for AntiVir

Posted by jpluimers on 2014/07/28

A short while ago, I wrote about Linux: getting the correct license file for AntiVir.

Too bad that I recently read about the Discontinuation of Antivirus solutions for Linux systems on June 30th 2016.

This means the hbedv.key cannot be downloaded any more.

Mac/PC: sending Wake-on-LAN (WOL) packets

Posted by jpluimers on 2014/07/25

I’ve succesfully woken up these machines:

  • HP XW6600 running ESXi 5.1
  • ThinkPad W701U running Windows 7

I still need to try to wake up a Mac Mini Server running OS X 10.6 (Snow Leopard).

MacBook Air on 10.7 (Lion) and Retina on 10.8 (Mountain Lion) won’t work as they are WiFi only, and WOL does not work over WiFi.

On 10.7 and up it might not work on a Mac Mini Server either, as Apple Introduced Dark Wake.

I used these tools to send WOL packets: Read the rest of this entry »

Using inotify-wait to check filesystem events

Posted by jpluimers on 2014/07/21

Thanks to Using inotify-wait to check filesystem events I got pointed to How to use inotify-tools to trigger scripts on filesystem events which is now on my research list.

–jeroen

Note that Kristian later on commented this:

The solution shown in the article has race conditions and should not be used.

It is based on

while :
do
inotifywait $options && run-backup
done

and that means that while the backup runs, the directory in question is unmonitored. When the backup finishes, new changes may have been accumulating during backup run, but without being picked up by the backup.

A proper solution would do something like

inotifywait -m $options | while read line
do
do-something-that-logs-multile-changes-and-triggers-backup-once
done

The important thing is that “inotifywait -m” does not terminate and hence no changes will be lost. It is wrong to run the backup once in full for each change, though.

BitTorrent Labs: BitTorrent Sync – distributed peer-to-peer syncing your files without online cloud storage

Posted by jpluimers on 2014/07/18

Interesting for people that do not trust Cloud Storage providers: BitTorrent Labs’ BitTorrent Sync.

I’ve tried an early version, and it works “OK”. Not yet as well-integrated like for instance DropBox, but stable and fast enough.

Important thing for me: works on *nix, OS X and Windows. Hopefully mobile devices will follow soon.

At the time of writing (May 2013), it is the only cross platform freeware entry in Comparison of file synchronization software – Wikipedia, the free encyclopedia.

In the mean time, Thomas Mueller (dummzeuch)wrote a nice blog post with background information on this: Bittorrent Sync, a secure DropBox alternative » twm’s blog.

HTTP debugging tools

Posted by jpluimers on 2014/07/15

Any web developer should know how to capture and trace HTTP traffic.

I’ve written about Fiddler before, but that’s a Windows specific tool.

Time to have a small list of posts and links to tools that work on various platforms.

I’ve left out Java based tools as there have been too many security issues with Java over the last couple of years.

Tools: Read the rest of this entry »
