vche: Serious as it gets

2014-10-01-6m47421-vche

I promised something a little more serious today, and I can think of nothing more serious than a hex editor. Here’s vche:

2014-10-01-6m47421-vche

I did run into a short list of hex editors for the console a few weeks ago, which is why vche is up now and why aphex was listed 10 days ago. Which is all the more curious because, as I say every time I see a hex editor, I almost never have any use for a hex editor.

All the same, I like a few things about vche that might not (or might) be part of the hex editor you use:

  • Plenty of color, and well arranged. It’s easy to see what and where you’ve edited.
  • Has separate versions for consoles and X-ish environments, and one that’s flexible enough for either case. I don’t know exactly why that’s necessary, but it does mean there’s a version that won’t show my favorite block character where the font fails a terminal window.
  • Has one-key presses for XOR, OR, AND and other bit operations. Again, not that I would never need that, but it’s cool.
  • Has a quick jump between ASCII and hex editing with the TAB key. It seemed natural to me, so I had to mention it.

vche has a lot of other clever tools on board. I’ll let you take a closer look and see if something tickles your fancy.

I must be honest and say that I did have a little screen corruption, but only when the help window appeared. And if I must be honest again, that help window is not a help window. All it does is tell you to look at the man page. We can do better than that, people. …

I have a few more hex editors to show, but I’ll space them out over the weeks to come. I don’t mind lumping games (particularly minesweeper games) into a single post, but I think an oh-so-serious tool like a hex editor should probably be taken on its own. :|

P.S.: If you find you like vche, you might consider adopting the Windows version for your other machines.

Testing A WINS Server

On a CIFS/SMB domain the WINS service is critical for proper function [some things use WINS, some things use DNS, it is terribly confusing, but it is what it is].  DNS is relatively easy to test and you will likely know right away if it isn’t working.  But before adding those new DCs to your dhcpd.conf file -

option netbios-name-servers 192.168.1.78, 192.168.1.79, 192.168.1.65;

 – it would be nice to be equally confident WINS is operating as expected.
To that end the Samba package provides a useful tool nmblookup which support querying of a WINS server much like host/nslookup does for DNS.

$ nmblookup –unicast=192.168.1.65 –recursion arabis-red
querying arabis-red on 192.168.1.65
192.168.1.58 arabis-red
$ nmblookup –unicast=192.168.1.78 –recursion arabis-red
querying arabis-red on 192.168.1.78
192.168.1.58 arabis-red
$ nmblookup –unicast=192.168.1.79 –recursion arabis-red
querying arabis-red on 192.168.1.79
192.168.1.58 arabis-red

The –unicast option specifies the IP address of the WINS server; but this option is only effective in the expected way if used with the [oddly named] –recursion options. Without –recursion the –unicast will not cancel use of the NetBIOS name resolution logic.
One other useful feature of nmblookup is the –translate option.  This option invokes a reverse DNS search on the IP address returned by the WINS query – allowing one step verification that WINS and DNS are on the same page.

$ nmblookup –unicast=192.168.1.79 –translate –recursion arabis-red
querying arabis-red on 192.168.1.79
ARABIS-RED.example.com, 192.168.1.58 arabis-red

Pandora Client `Pithos` 1.0.1 Released With Bug Fixes

pithos
Pithos 1.0.1 was released recently and it includes some minor improvements and bug fixes – for instance, the bug that was causing the Ubuntu Sound Menu to stop working when using Pithos was fixed in this release.

Pithos Pandora client

For those not familiar with Pithos, this is a simple Pandora.com client which includes features such as:
  • cover art;
  • thumbs up / thumbs down / tired of this song options;
  • allows switching between Pandora stations;
  • allows editing QuickMix and creating stations;
  • desktop integration: Ubuntu AppIndicator, notifications, MPRIS v2 support – so Pithos integrates with the Ubuntu Sound Menu / GNOME Shell Mediaplayer extension;
  • media keys support;
  • proxy support;
  • last.fm scrobbling.

Pandora is a music streaming and recommendation service that’s only available in the United States, Australia and New Zealand. You can use it in any other country with an US proxy, VPN, a DNS service or with Tor and SelekTOR.

Changes in Pithos 1.0.1:

  • Automatically install missing codecs if supported;
  • Save window position between sessions;
  • Fix saving last station on quit;
  • Fix pacparser support;
  • Improve pandora module docs;
  • Add setup.py command to build docs;
  • Add appdata file;
  • notification_icon: Make toggling visibility more reliable;
  • mpris: Fix exception when querying position;
  • mpris: Implement setting volume;
  • screensaver_pause: Improve Unity support;
  • OSX: mediakeys and notify support.

Install Pithos in Ubuntu 14.04 or 14.10 / Linux Mint 17

Pithos is available in the official Ubuntu repositories, but that’s a pretty old version. To install the latest Pithos in Ubuntu 14.04 or 14.10 / Linux Mint 17, you can use the official Pithos PPA:
sudo add-apt-repository ppa:pithos/ppa
sudo apt-get update
sudo apt-get install pithos gir1.2-gst-plugins-base-1.0

Arch Linux users can install Pithos via AUR.

For other Linux distributions, see the install section from the Pithos homepage (the app should also work on Windows and Mac, but there are no binaries for now).
Report any bugs you may find @ GitHub.
