Thunderbird is so slow... it's nearly unusable!?

I have been using Thunderbird for a long time and yet I still did not know about the Compact feature.

A while back, i would use my Local Folders to save Junk, Draft, and Sent emails. This is really fast by default. But at some point I had a problem and reverted to using the remote folders which worked.

The problem was that Thunderbird would tell me that my Local Folders were full even though looking at them they were clearly empty.

The way this works is really annoyingly bad:

1. it accepts emails in a file, like the good old days, it uses one file for any number of emails

2. it adds new ...

Boot into the command line console in Ubuntu 16.04

As I just upgraded my 14.04 installation to 16.04, it booted right up to lightdm.

I had it properly setup to boot in a console before, but somehow it changed the behavior on me.

This is because the computer is now using systemd to boot.

I already had the GRUB variables setup as expected:

GRUB_CMDLINE_LINUX_DEFAULT="text"
GRUB_CMDLINE_LINUX="text"
GRUB_TERMINAL=console

But this is not enough if you want to start in the console when running systemd (which is running since 15.04).

systemd has a list of variables you can tweak using the systemctl command. To boot in ...

Gnome Keyring stopped working...

At some point in time, I upgraded Ubuntu and my Gnome Keyring stopped working. So each time I do ssh I have to enter the password at the prompt and that's a bit annoying after a while (depends how much I access the servers, obviously.)

I read many threads ZERO of them gave me an answer I want to hear. All of them speak of things that do not make sense in that situation. So I tried to install a brand new clean 14.04 server + ubuntu-desktop and guess what... Gnome Keyring is installed and everything makes me think that is is correctly installed (I get the correct SSH_AUTH_SOCK value) and ...

Lost SSH key graphical prompt and auto-add to SSH agent

At some point in the past, my system somehow lost the ability to avoid asking me for my key every time I connect to one of my servers. It generally okay, I don't do so much work on that server that I'd have to connect all the time...

However, it is annoying when, once in while, I end up doing a lot of work, back and forth.

The ssh-agent was installed and working. I could add the key manually:

ssh-add ~/.ssh/my-secret-key
ssh-add -l

The ssh-add command allows you to add and remove keys from the ssh-agent. The -l command line option lists the keys currently held by the agent.

Bad move for PHP unpack()! So unpack() stopped working?

Today I noticed many errors on one of my websites. Looking closer into it, I noticed that the code for the mo_references Drupal module stopped working.

It took me some time, especially because the code seemed to work just fine as all the files could easily be displayed.

Actually, that was not the case. The unpack() character 'a', which I used, was transformed from a simple string that gets trimmed, to all the characters, including the NULL characters. Ouch! Now we have to use the 'Z' character instead.

I use it to unpack() a tar file by loading 512 bytes of data in a ...

Console color: dark blue on black unreadable

As I work in consoles every now and then, I run in that one problem:

Some text is written in Dark Blue over the Black background:

This is a good example of what I'm talking about.

And if you can read that text, wow! (without selecting it first.

So... how could you change the color of that blue to make it readable? There is a way by sending some escape command to the console:

echo -e "\\e]R\\e]PC6495ed"

That command changes the color of the blue to a light blue (somewhat "cyan", although not light cyan.)

The "\\e]R" part is to reset the colors to ...

Classes in JavaScript (from complex objects to proper classes)

When creating objects (commonly called JavaScript classes) in your JavaScript code, you want to use the prototype. This is the only clean way of doing it. In JavaScript, you can create objects on the fly, but those are not considered safe.

Quick and Dirty

The quick way is to create an object directly. This works, but it has potential problems with used against a powerful optimized such as the Google Closure Compiler.

All the Quick and Dirty examples can make use of this in their myFunc examples. However, the closure compiler will warning about all of them because it doesn't know for ...

Large scale Linux console

As I am working on our Snap! C++ CMS, I created a set of virtual systems to test the compilation on "clean" system (yeah! my main computers has all sorts of things that I don't even know about...)

In those virtual system, I only install the basic server and then do a sudo apt-get install of anything else the server needs to get compiled. This includes libraries such as libmagic, boost, and Qt and some tools like xmllint. This is pretty cool, but when working in a console, and that console is very small, it makes it a bit difficult, so I looked into making it big.

For this ...

My NVG 510 broadband light is blinking red

Somehow my NVG 510 broadband light started blinking red a couple of time in the last few days. I've been wondering why and I think I have the answer now.

In most cases it may just be that the broadband signal disappears for too long and the modem disconnects.

However, in my case, I think it was because they made an upgrade (a push!) on the modem because a few things do not work as expected anymore. (i.e. I cannot access the nsh shell anymore...)

Whenever software is upgraded, the likelyhood that you have to reset the whole thing is very high. I had to restart twice and even after that, ...

Useful online network tools

I'm starting this page and hope to think about it again at a later time when I find additional tools... but as I have network problems I often need these types of services to make sure I can get the information I need.
