What To Write In A Sympothy Card

Synergy - Installation and Security Resources

Synergy - redirect your mouse and keyboard

At the outset I am tempted to give a brief description of this very interesting program. The name of the program is an existing word in the dictionary it means "common, useful combination of different elements." The program allows us to easily share a single keyboard and mouse between multiple computers. They may have different operating systems do not require any special equipment, but each must have its own monitor.

In Synergy redirect mouse or keyboard is very simple: just we move the mouse cursor to a predefined corner of the screen and the program takes input keyboard and mouse to another computer. This way you can use these devices to the computer to which they are linked. All communication is done via the network, of course, not restricted to the normal LAN connections . Synergy can also be used via a wireless network connection.

Synergy

Additional advantages are:

able to use the clipboard, gives us an opportunity copy text between computers (and operating systems) using Ctrl + C, CTRL + V
also have the ability to synchronize screen savers, in addition disable the screen saver requires a password, then you can unlock all savers giving them only once
is program for open access to the source code is available under license GNU Public License

System Requirements:

MS Windows 95/98/ME
MS Windows NT/2000/XP
Mac OS X 10.2 or later
Unix (Linux, Solaris, Irix and others)

X Windows version 11 revision 4 or later
extension XTEST (to check whether you have this extension requires the execution of a command " xdpyinfo Architecture independent packages, with binaries for Windows only in 32-bit.

Windows

: If you do not compile from source is simply run the installer, choose the installation path and the case.

Linux: If you are using Debian as I am, then no problem and simply type:

apt-get install synergy

and the matter resolved. If, however, it became clear that we did not find this package we can find the page

Debian packages and then install the issuing command:

dpkg-i [package name] For other systems, or looking for an appropriate package or download the source
Synergy.
Compiling from source
- what we need?

 
 
 Windows: VC + + 6.0 or later,

Unix: gcc 2.95 or later and the libraries and header files for X11R4
-
Configuration (for VC + + or XCode, you can skip this step)

. / Configure
. / configure - help
In this way, configure Synergy for our system. The second line displays the configuration options available to us. Of course, we issue these commands in the directory where you extracted the source. - Compiling and Installing

- turn on VC + + and open synergy.dsw. Set the active configuration (bulid -> Set Active Configuration) to All - Debug or All - Release and compile. The binaries will be located in the directory. / Debug or. / Build. Then just copy the files from the debug directory to the directory, eg Program Files / Synergy (These files are: synergy.exe, synergyc.exe, synergys.exe, synergyhk.dll).

Unix - type:

make make install

client and server will be installed Synergy
in the directory / usr / local / bin
unless you specify otherwise.

Security

 Synergy does not have any built-in mechanism for authentication and encryption. Each computer can connect to the server if he presents Synergy screen name known to the server. In addition, due to the fact that the data is sent in encrypted form, anyone can capture the depressed Our key and thus even a password. For this reason, Synergy should be used in trusted networks. 
 
 However, there are tools that can add to the Synergy mechanism for user authentication and encryption, without modifying any of the programs. One of these tools is

SSH, a free implementation of SSH is OpenSSH called
and works on linuxach, most Unixes and Windows (in combination with Cygwin

Server Configuration Synergy

install the OpenSSH server on the same machine as the server Synergy. Configure OpenSSH server as usual and run it. Now start the server Synergy. Neither Synergy or OpenSSH does not require any additional options.
Synergy Client Setup

Install OpenSSH client on each machine that has Synergy, then znich run on each client with the option of SSH port forwarding:

ssh-f-N-L 24800: name-server: 24800 server-name server-name is the name or address of the computer that is running OpenSSH servers and Synergy. Port 24800 is the default port being used by Synergy. If you use a different port, change port numbers in the above command. At the end of the run Synergy clients by replacing the server name localhost
.
synergyc f localhost

After that Synergy will use a secure connection with clients thus eliminating the possibility of steal information.

What next?

In the next post I will describe how to configure and use server Synergy and the client. As an example, I use my laptop for example, indicate who is working as a server. As I put myself on the server in addition WiFi network, so from anywhere in the house using a laptop touchpad and keyboard can I play other computers: D

Samba player Amarok

Amarok and remote resources

As you probably noticed Amarok does not have built plug-in for the SMB protocol

, now begs the question - How to play music files located on another computer?

If these are shared resources of your Windows computer, or if the remote computer we have installed Samba and use it to share files, play them in Amarok is quite simple. We will not however play Amarok settings, because they do not find an answer. We

and install (if you do not have this package) package smbfs

smbmount . The syntax is:

mount-t smbfs-o username = user, password = pass / / Serer / udostepniony_zasob / local / directory
smbmount-o username = user, password = pass / / Serer / udostepniony_zasob / local / directory

After such "cosmetic" surgery add music files from a directory

/ local / directory directly into Amarok, and we can enjoy the music. Additionally, you can set the assembly of these resources during the system boot in another case, after reboot once again we have to use one of these commands.
If you are not sure of the name Use a remote resource Command
smbtree
or
smbclient-U username-L servername . Both are in the smbclient package . After executing this command will show us the tree of Samba, or a list of resources when using smbclient.

Windows - Repair the boot sector and MBR

Windows - Repair the boot sector and MBR

The tutorial on recovering GRUB
wrote that by accident we can prevent the loading of Windows when the computer starts. I actually typing

grub-install / dev/hda1

Where / dev/hda1 is the partition

with Windows, this is what happen.

We now have a corrupted bootsector ... What's next?

It turns out that the repair in this case, fortunately, is not too difficult. The only thing we have to do is find a tile installation with Windows and run with the computer. Then, after loading all the drivers and other garbage (D) to select the option

R or repair the system (generally enter into recovery mode.) Are moved to the console windows.
Now execute the following commands: fixmbr

fixboot c:

 Then, if you've come here because of grub do again what was written in a tutorial on the recovery 
 grub after reinstalling windows 
 and everything will work as expected .

If you're a Windows user simply reboot the computer and enjoy operating system again.

Odzykiwanie GRUB after reinstalling Windows

 
 Odzykiwanie GRUB after reinstalling Windows

If we have two operating systems such as Debian and Windows XP (as in my case), we encounter a problem with an appropriate system after reinstallation of another (in fact it is only for reinstalling Windows, P).
I refer to overwrite the MBR

by Windows. If you use a boot manager like GRUB or LILO, for example, then you may find that after the reinstallation of Windows in general GRUB will not start.

So we have a problem - we must somehow recover the grub in the old way if we want to work on both systems.

start up from CD

First, we need to boot from the CD. This could be your installation disc operating system (Debian, Slackware, Gentoo, etc..) Or rescue disk. Rescue disk is the most minimal Linux system on a CD. I personally use is the second solution in the form of Timo's Rescue CD Set
. When you turn on your computer, go to

uiw BIOS settings, change the boot order to CDROM for example, C DISK, FLOPPY is possible to boot from the CD. However, in most current computers simply during startup press F8 and select the appropriate device from the list. Then, when you use the installation CD after booting up, hit all the required elements ALT + F2 (or CTRL + ALT + F2) to go to another console and get access to the shell. However, if

Timos Rescue CD Set
log in using the following data: user: root password: rescue
GRUB Recovery
Now we are only a few simple steps to do: First, display the partition table fdisk our device
-l

Now we are looking sign for a partition Linux installed, it may look like in two ways: SCSI eg / IDE dev/scsi/host0/bus0/target0/lun0/part1 eg / dev/hda4 . Once we identify the device, we need to mount them using the command mount

Now we use the chroot command

to launch an interactive shell with special parent directory, eg / mnt / mojDysk will be used as /

final step is to re-install GRUB:

Complete Exit from the shell, remove the disc from the CD-ROM drive and restart your computer. Now everything should work correctly.

Attention! Do not type in the command grub-install

value style

! Use only the device ID. Eg If you enter the partition ID with Windows (in my case

), you will need to recover the MBR for windows, and once again play with the GRUB recovery.

MathML - Presentation on Web pages

Theory

MathML markup language is a modern, well-suited for the presentation of mathematical content on the websites, it also enables conversion of symbolic expressions using scientific software (Computer algebra systems), such as Maple or Mathematica. MathML is a tool designed specifically to record athematic expressions (mostly of their construction) is recommended for this purpose by the WWW Consortium (W3C

). MathML is not part of XHTML, it is built like a separate language for XML-based XHTML. Do not expect so that everyone understands the marking scheme will be properly format the XHTML MathML expressions. However, all understood the XML browser should cope with MathML. For the correct interpretation of MathML You need to provide information about the syntax (DTD) and a line of content items (styles). Information of the elements and set the style to be transmitted via a browser command header XML.W3C language has developed recommendations for the direct deposition of elements of the language MathML in XHTML documents, they found expression in the formal specification known as XHTML 1.1 + MathML-2.0. MathML has two ways of marking: presentation and treściowy. The first one is focused primarily on the use of typography and the second - mainly to perform calculations.

 Presentation MathML   
  to make a presentation to the XML document we use the styles, if there is no fixed  style - there will be a presentation of an XML element. Today 
 can be used to create styles:     CSS - Cascading Style Sheets 
  JSS

- styles, JavaScript, and XSL

  
 - styles of presentational language derived from XML

Even if we provide a style for your browser, you may find understand that some of it and the other not, for example:

Opera (v 7.21)

- understands very well the CSS styles, but does not implement XSL.

Internet Explorer - Problem with XSL transformations. They are disabled by default if the IE security located on a server other than the XML document. The solution is to put them in a directory that uses the XML transformations. In addition, it also has display problems. The solution is to install MathPlayer. It is available at:
http://www.dessci.com/en/products/mathplayer/

Mozilla

- No fonts needed to display the formulas. The solution is to install them using the installer from the website:
http://www.mozilla.org/projects/mathml/fonts/

generally can independently interpret the markup presentation, however, can not cope with markers treściowymi unless we provide the appropriate styles. Other browsers using the Gecko engine to display web pages, eg

Mozilla Suite (now in draft unsupported)
Firefox SeaMonkey

Netscape 6.x 7.x, 8.x (in parallel with motor Trident)
It supports a MathML-to such an extent as Mozilla.

There is also a problem with formatting via CSS - considerable reduction in the control order and the mutual position of boxes zawierającyh formatted expressions. For this reason, there are complete sets of styles for MathML written in XSL.

NOTE:

XHTML 1.1 + MathML-2.0;
The correct interpretation of the language elements of MathML in browsers such as
follows:

first

name and MIME type of document:

MathML expression, and the root element math. Of course you must take care of such a configuration server to send the headers.

second

Document Preamble: The preamble must be included: the declaration of the XML version of the declaration of the code used information, the declaration sheet Style and the declaration of the document type definition DTD. We use the following header:

\u0026lt;? Xml version = "1.0" encoding = "iso-8859-2"?>

\u0026lt;? Xml-stylesheet type = "text / xsl" href = "http://www.w3.org/mathml.xsl?> \u0026lt;! DOCTYPE html PUBLIC" - / / W3C / / DTD XHTML 1.1 plus MathML 2.0 / / EN "
" http://www.w3.org/TR/MathML2/dtd/xhtml-math11-f.dtd ">

\u0026lt;html xmlns =" \u200b\u200bhttp://www.w3.org/1999/xhtml "

xmlns: math = "http://www.w3.org/1998/Math/MathML"> followed these simple XHTML head and body elements. If the document uses only presentation MathML notation, it is enough to pmathml.xsl style. You must change the entry in the declaration of the stylesheet (pmathml.xsl mathml.xsl instead.) It's worth doing, because sending and processing will be shorter.

third

stylesheet processing problems in IE:

IE by default, refuses to be formatted XML document downloaded from a server based on a set that was downloaded from another machine. For this reason, the style sheets:

ctop.xslmathml.xslpmathmlcss.xslpmathml.xsl

we need to copy to a directory on the server provides the document and modify the path in the preamble, so that the did not show:

\u0026lt;? xml version = "1.0" encoding = "iso-8859-2"?> \u0026lt;? xml-stylesheet type = "text / xsl" href = "[nazwa_katalogu_ze_stylami] / mathml. xsl "?>
\u0026lt;DOCTYPE html PUBLIC "- / / W3C / / DTD XHTML 1.1 plus MathML 2.0 / / EN" "http://www.w3.org/TR/MathML2/dtd/xhtml-math11-f.dtd">

\u0026lt; ; html xmlns = "http://www.w3.org/1999/xhtml" xmlns: math = "http://www.w3.org/1998/Math/MathML">

4th
Problems with DTDs:

If we have problems just from the DTD it should again change the contents of the preamble:
\u0026lt;? Xml version = "1.0" encoding = "iso-8859- 2 "?>
\u0026lt;? Xml-stylesheet type = "text / xsl" href = "[nazwa_katalogu_ze_stylami] / mathml.xsl?> \u0026lt;! DOCTYPE html PUBLIC" - / / W3C / / DTD XHTML 1.1 plus MathML 2.0 / / EN " [nazwa_katalogu_z_DTD] / mathml.dtd">

\u0026lt;html xmlns = "http://www.w3.org/1999/xhtml" xmlns: math = "http://www.w3. org/1998/Math/MathML "> And as mentioned above, this time to put the sheets in the DTD directory on our server. While the file [nazwa_katalogu_z_DTD] / DTD mathml.dtd contains truncated, containing only the declarations of individuals.

Negative Pregnancy Test Three Days Before Period

[Harvey Danger - Flagpole Sitta] - Just to relax!

Lyric
I had visions, i was in them

I was looking into the mirror

To see a little bit clearer

Rottenness and evil in me And when i feel a bit naughty
I run it up the flagpole and see who salutes

(but no one ever does)

And i don't even own a tv

Put me in the hospital for nerves

And then they had to commit me
You told them all i was crazy

They cut off my legs now i'm an amputee, god damn you

I'm not sick but i'm not well

And i'm so hot cause i'm in hell

I'm not sick but i'm not well
And it's a sin to live so well
I wanna publish zines
And rage against machines
I wanna pierce my tongue
It doesn't hurt, it feels fine
The trivial sublime
I'd like to turn off time
And kill my mind
You kill my mind
Paranoia paranoia
Everybody's coming to get me
Just say you never met me
I'm going underground with the moles
Hear the voices in my head
I swear to god it sounds like they're snoring
But if you're bored then you're boring
The agony and the irony, they're killing me
I'm not sick but i'm not well
And i'm so hot cause I'm in hell I'm not sick
but I'm not well
And it's a sin to live so well

Apache 1.3 - Installation

NOTE:
Apache 1.3 + Debian 4.1

- Introduction -

"Apache is the most widely used HTTP server on the Internet. In May 2006, its share among servers accounted for nearly 65%. In combination with an interpreter for the PHP scripting language and MySQL database, Apache is one of the most common environments in companies that offer a place on network servers. Netcraft, a company specializing in monitoring the Internet, in July 2007 examined more than 100 million Web sites. It turned out that the share Apache'aw Web server market now amounts to 48.42% and the share of Microsoft's IIS - 36.21. Similar studies in November 2005 showed that the Apache has a 71% market share and Microsoft less than 20%.

Apache / PHP is a competitive platform for Microsoft's ASP.NET technology, based on the commercial IIS server. Along with PHP and MySQL database engine on Linux, Apache is called. LAMP platform (Linux, Apache, MySQL, PHP). "

[Source:

http://pl.wikipedia.org/wiki/Apache_ (server)
1). Install using apt-get

After installing Debian, we have typically entered

source file / etc / apt / sources.list . In this case, type in console:

$ apt-get update

$ apt-get ugrade

$ apt-get install apache

And it's basically the whole philosophy. Of course, if you want to install additional modules for Apache to enter:

$ apt-get install libapache-mod-[module name]

In order to check what modules are available from our sources type:
$ apt-cache search libapache-mod

And if we know what we are looking for something such as: $ apt-cache search libapache-mod
And yet another way to install, this time with sources. After downloading the file from the source (eg apache_1.3.39.tar.gz) must be decompressed. After entering the appropriate command will extract the source of the current directory:

Extracting. "Tar.gz"

$ tar zxvf package.tar.gz

Extracting ". Tar.bz"

$ tar package xvjf . tar.bz

Extracting. "bz"
$ bunzip2 file.bz

Extracting. "gz" gunzip $ file.gz

Then we need to configure the source (as regards the detailed description of the options available to invite you to read the file README.configure in the source directory).

To see the available options, we can also write: $. / Configure - help

So to configure the source type:
$. / Configure

then build a package with Apache using the command:

$ make

Please be patient as this may take a while. This time depends on the number of modules which załączymy.

final step is to install - type in console:
$ make install

- Complete -

Now just make sure that everything works as it should. For this purpose, we use the script located in the directory / etc / init.d. It is used as follows:
$ / etc / init.d / httpd {start own needs, but it will be part of the next post.

NOTE:
read the messages carefully especially if the installation fails!

For installations with dpkg it may be a lack of other packages. Deb, which requires apache, then I recommend going on:
http://packages.debian.org/stable/web/apache
If Install from sources mostly by typing
. / configure
turns out that we are missing some libraries or simply do not have installed the compiler (eg gcc

.) Then when you set up the communications to be przyjżeć and robin doinstalowywać required libraries or programs. May prove useful *. log file from the source directory. Writes in it all the installation steps and showing the errors.
