The Linux Page | Linux Geek

Using libbfd.a to load your own ".dll" files

Noticing that this is a rather old link, there is my own implementation of the EDLL in case you had not found it yet!

This Enhanced DLLs page is the first I wrote before starting on the project for real.

This works great with MinGW and does not require to have all symbols defined in a tree like definition. (i.e. these DLLs can link back to the main executable, just like under Linux and many other Unices.)

Using your firewall with Postfix

After a little while (very little) our mail server gets quite clogged. It does not cause much problem to our server, however, legal mail server will have a hard time to connect because all of those illegal mail server connect thousands of times to try sending us spam.

To give you an example, I blocked less than 10 IPs today and I got over 5,000 hits blocked within about 12 hours. That's to give you a picture of the badness of those scam robots.

Variables and Functions in VBA not like in C++!

I have been writing C/C++ code for... well... over 10 years.

I'm always surprised when I use another language and some basic rules are completely different.

/var is 99% full...

Problem

On Unix systems, you create partitions and assign them a folder such as /usr, /home, and /var. Many people like to put different things on different partitions. Very frankly, it is often complicated to do that, so if you don't have a real need, only break up the /home and /tmp folders from the rest. The /var is a good idea to break up if you use databases or very heavy logs. The /etc can be separate mainly for ease of backup.

View & Track tabs in Drupal sites

If you have your own Drupal site, you may have noticed a set of tabs appearing at the top. The View and the Track tab often appear on your site even for anonymous users. This is really annoying!

Here I show you what I see when I go to one of my pages. The View, Edit and Track tabs.

Visual C++ for free!

Download a free copy of your C++ development environment! (Visual C++ v8.0)

Yes! Microsoft is doing the same thing as Linux: they offer their IDE for free with their fully compliant C/C++ compiler (as well as other bits if you are interested, I only want C++ on my end!)

At this time, the link is like this:

warning: connect to 127.0.0.1:60000: Connection refused
Today, I noticed many entries in the log of my mail server with this error:
```
   warning: connect to 127.0.0.1:60000: Connection refused
```
The fact is that this does not tell you anything (duh!)

We use postfix which runs many servers and each server talks to the other via network messages. Up to here, nothing special. The problem is whenever a server cannot connect to another, instead of telling us who, what, when, it just tells us that the connection did not happen (although there is the date, but it does not tell you when in the chain of events.)

What is an RSS feed?

An RSS feed is very common on all new websites. It has been around for years now. As of today you could listen to thousands of RSS feeds and be totally swamped by all the news...

But what is an RSS feed?

The way users know about RSS feed is in the form of a URL. The URL points to a file on a website that includes data. That data file uses the specific RSS or RDF format, which uses XML as the base format.

What the hell is that My Documents stuff about?!
Look at the SHGetSpecialFolderPath()1 function! You can actually use names such as "My Documents" and transform them a valid path as you would expect (i.e. C:\Settings & Stuff\username\My Docs\...).

And yes! If you have no clue about that function, that's not going to be easy to find it...
- 1. The SH stands for Shell. The explorer windows are considered shells under MS-Windows. Nothing to do with a real good Unix shell, of course.

Windows 2000 SP4, new logon policy forced to Roaming by default.

Not too long ago, I accepted the update from Microsoft to go to MS-Windows 2000 SP4. Neat. Except that when I rebooted (I think the 2nd time, but not totally sure, my wife used the computer in between, it seems...) it could not load my profile anymore.
