Hide passwords with Steghide

StegHide hides data in picture and sound files, where not all bits in the byte are used. Since the data is encrypted, it is very difficult to prove its presence. The only problem with sizes - to hide megabyte of encrypted data, you will need audio or picture file sizes of several megabytes.

Laptop as a wifi access point

I know that it is possible to make an access point from a wi-fi card. Now I tried to set it up. Here is a description of my actions step by step.

I have old laptop Acer Aspire 5315.

OS— Kubuntu 11.10

Wi-Fi-card— Atheros. That's what lspci says about it

Ethernet controller: Atheros Communications Inc. AR242x / AR542x Wireless Network Adapter (PCI-Express) (rev 01)

 

Of course it have ethernet card too.

Compose settings for entering non-standard characters

When typing texts is often necessary to use characters that are not present in your layout, or not presen on keyboard at all. For example, typing something like ¼ or ‰ is a non-trivial task. Of course, you can use a character table and just copy everything from there. But it is good when the desired character is entered 1-2 times. And what to do if you need it constantly? This is where the Compose key comes to the rescue.

 

The compose key is also known as "Multi_key" at the X Window System. In X.Org Server, many keyboard layouts provide different options for the location Multi_key, commonly used in PC-compatible architectures.

You can assign this key in different way. For example, using XkbOptions ("compose: rwin"). In my Kubuntu it can be done in Kmenu-Computer-System Settings-country/region/language. I assigned a button to the Compose key that I never use - CapsLock.

Now let's go through the settings step by step
