Why-dont-you-use-Window-Maker-graphical-environment-for-your-GNU_Linux-FreeBSD-desktop

If you're pissed off too already of GNOME 3 Unity / GNOME 3 Flashback and KDE Plasma  as I am you perhaps are looking for something more light weigth but you're not okay with default Debian Cinnanom GUI environment or you don't feel confortable for system administration jobs and programming with XFCE then perhaps you would like to give a try to something more old school but build with good design in Mind.

Those who are fans of the evil genius Steve Jobs (as Richard Stallman use to call him), definitely Remember NeXT company and the revolutionary Graphic Environment they tried to develop NeXT Step then you'll be happy to hear about GNUStep  which historically was called AfterStep and is a Free Software remake of NextStep graphical environment for Free and Open Source operating systems (FOSS) such as GNU / Linux and FreeBSD / OpenBSD / NetBSD etc.

Amanda the Panda is the mascot of Window Maker. She was designed by Agnieszka Czajkowska.

The good thing about Window Maker and the complete bunch of desktop environment GNUStep is it much lighter and less complex than the more and more becoming bloated modern Free Software graphical environments, it definitely easifies the way the user interacts with basic browsing with Firefox / Opera, terminal code writting or command system administration and basic chat functionalities such as with Gajim or Pidgin and basic email writting operatins be it with some text email client such as Mutt or with Thunderbird. Its great also to reduce the overall load the Operating System puts on your brain so you can have more time to invest in more useful stuff like programming.

After all simplicity in Operating System is a key for an increased productivity with your computer.
Besides that stability of Window Maker is much better when compared to GNOME and GNOME 2 fork MATE graphical environment which nowadays in my opinion is becoming even more buggy than it used to be some years ago.

Below is how Window Makers site describes Window Maker:

"Window Maker is an X11 window manager originally designed to provide integration support for the GNUstep Desktop Environment. In every way possible, it reproduces the elegant look and feel of the NEXTSTEP user interface. It is fast, feature rich, easy to configure, and easy to use. It is also free software, with contributions being made by programmers from around the world.

Window Maker has a stable user interface since many years and comes with a powerful GUI configuration editor called WPrefs, which removes the need to edit text-based config files by hand. It supports running dockapps which make everyday tasks such as monitoring system performance and battery usage, mounting devices or connecting to the internet very easy. Please see the features section for more specifics on what Window Maker can do, and how it compares with other popular window managers."

Window Maker is bundled with a number of useful applications which gives ability to put Dock applets easily for easily intearcive desktop update of current Weather Report, Monitoring Network Traffic, TV Player (video4linux), laptop battery info dock, CD player and Volume control management app, text editor, pdf viewer, integrated Mail application, Calculator, RSS Reader, GNUStep gamesand much useful things to customize from the desktop resembling many of the basic features any other graphical environment such as GNOME / KDE Provides.

The User Interface (UI) of Window Maker is highly configurable with an integrated WMaker tool called

WPrefs

Why-dont-you-use-Wmaker-for-better-desktop-performance-Windowmaker_colour_preferences

All generated settings from WPrefs (Window Maker Prefernces) GUI tool are to be stored in a plaintext file:
 

~/GNUstep/Defaults/WMRootMenu

All Wmaker configurations are stored inside ~/GNUstep/ (Your user home GNUStep), so if you're to become its user sooner or later you will have to get acquired to it.

Wmaker is very minimalist and the performance is killing so Window Maker is perhaps the number one choice Graphical Environment to use on Old Computers with Linux and BSD.

Below is a full list of all packages installed on my Debian GNU / Linux that provides WMaker / GNUStep great functionalities:

Well yes it is true Window Maker is not a spoon for every mouth, those who want to have more confortable desktop environment better look out at other options as Window Maker is Unix / Linux graphical environment that fits better hackers, computer developers and system administrators.

Anyhow if you have some old family member that has to use an old computer architecture and the person is only to use mainly just browser to check email, youtube and basic surfing then Wmaker will be a great choice as it will consume little CPU and Memory much less than the heavy and computer resources sucking GNOME and KDE.

I've historically used Wmaker also with its teminal emulator rxvt (VT102 terminal emulator for the X Windows System) which is a kinda of improved version of xterm (the default terminal program bundled with Xorg server), but for those who are already used to Gnome Terminal nice tabs perhaps that would be not the terminal of choice.

rxvt was build to match well the look and feel of AfterStep and consequently Wmaker, its scrollbar was aiming to very much resemble NeXTStep style scrollbar

Most "custom" shortcuts are used to launch specific applications. To add your own keyboard shortcut for an application, go to the "Applications Menu Definition" panel in the Preferences app.  Select the application item in the menu for which you want to create a shortcut, then use the "capture" button to capture the keystrokes you want to assign to that item.  In the screenshot, I've assigned Mod1 + W to open Firefox.

Above  screenshot shows how to map the Run Application keyboard bind to behave like GNOME Run application ALT + F2

Customizing background of Window Maker

Because WMaker is so simple made and targetting more of a developer audience for use it doesn't have a special graphical interaface to set a Background if you like so, but instead you need to use a wmsetbg command to do so:
 

wmsetbg -s -u filename.jpg

 

WMSetBG command stands for WindowMaker Set Background


If you're too lazy to install and start configuring wmaker, there is a Window Maker LiveCD, you can run Window Maker through LiveCD in Virtual Machine such as VirtualBox to get feeling what you're about to get if you install and start using Wmaker on your Computer.

Well at first with Window Maker you might feel confused and quickly irritating missing the already established way to work with your computer, but that's just for a starter sooner you will realize, that for using a limited number of applications for work wmaker, makes you much more efficient. Moreover using your computer with Wmaker can rewire your brain circuits to think a little bit different.

Once you switched to Window Maker you will likely want to have a graphical option to connect to Wireless Networks especially if you're using Wmaker on a notebook it is convenient to not always manually do scan for networks with

commad and use wpasupplicant command to connect instead you can just install wicd and stop default Gnome Network Manager (called Network Manager), you can do so by running as root:

How to turn keyboard backlight on GNU / Linux, keyboard no backlight solution

Friday, October 20th, 2017

Reading Time: 2minutes

how-to-make-CM_Storm_Devastator-keyboard_backlight-work-on-linux-enabled-disable-keyboard-glowing-gnu-linux

If you're a GNU / Linux user and you happen to buy a backlighted keyboard, some nice new laptop whose keyboard supports the more and more modern keyboard growing or if you happen to install a GNU / Linux for a Gamer friend no matter the Linux distribution, you might encounter sometimes  problem even in major Linux distributions Debian / Ubuntu / Mint / Fedora with keyboard backlight not working.

Lets say you buy a Devastator II backlighted keyboard or any other modern keyboard you plug it into the Linux machine and there is no nice blinking light coming out of the keyboard, all the joy is gone yes I know. The free software coolness would have been even more grandiose if your keyboard was shiny and glowing in color / colors 🙂

But wait, there is hope for your joy to be made complete.

To make the keyboard backlight switch on Just issue commands:

 

xmodmap -e 'add mod3 = Screen_Lock'

 

# Turn on the keyboard bright lamps
xset led on

# Turns off the keyboard bright lamps
xset led off


If you want to make the keyboard backlight be enabled permanent the easiest solution is to

– add the 3 command lines to /etc/rc.local

E.g. to do so open /etc/rc.local and before exit 0command just add the lines:

 

vim /etc/rc.local

 

xmodmap -e 'add mod3 = Screen_Lock'

# Turn on the keyboard bright lamps
xset led on

# Turns off the keyboard bright lamps
xset led off


If you prefer to have the keyboard colorful backlight enable and disabled from X environment on lets say GNOME , here is how to make yourself an icon that enabled and disables the colors.

That's handy because at day time it is a kind of meaningless for the keyboard to glow.

Here is the shell script:

#!/bin/bash
sleep 1
xset led 3
xmodmap -e 'add mod3 = Scroll_Lock'


I saved it as /home/hipo/scripts/backlight.sh

(don't forget to make it executable!, to do so run):

 

chmod +x /home/hipo/scripts/backlight.sh


Then create  the .desktop file at /etc/xdg/autostart/backlight.desktop so that it runs the new shell script, like so:

[Desktop Entry]
Type=Application
Name=Devastator Backlight
Exec=/home/hipo/scripts/backlight.sh
Icon=system-run
X-GNOME-Autostart-enabled=true

Play Midis on Linux / Make Linux MIDI Ready for the Future – Enable embedded MIDI music to play in a Browser, Play MIDIs with VLC and howto enjoy Midis in Text Console

Play Midis on Linux or Make Linux MIDI Ready for the Future – Enable embedded MIDI music to play in a Browser, Play MIDIs with VLC and howto enjoy Midis in Text Console HOWTO

 

Playing MIDI has been quite a lot of fun historically,

if you grow up in the days when personal computers were still young and the Sound Blaster was a luxury, before the raise of Mp3 music format, you have certainly enjoyed the beeping of PC Speaker and later on during 386 and 486 / 586 computers the enjoyment of playing tracked music such as S3M and MOD,

in that good days playing MIDI music was the only alternative for PC maniacs who doesn't own a CD Drive (which itself) was another luxury and even thouse who had a CD ROM device, were mainly playing music in CD audio format (.CDA).
Anyhow MIDI was a cheap and a CPU unintensive way to listen to equivalent of favourite popular Audio Songs and for those who still remember many of the songs were recreated in MIDI format, just with a number of synthesized instruments without any voice (as MIDI is usually).

The same was true also for the good old days of raise of Mobile Phones, when polyphonic was a standard as CPU power was low MIDI was a perfect substitute for the CPU heavy Encoded MP3s / OGG and other formats that required a modern for that time Intel CPU running in 50+ Mhz usually 100 / 166Mhz was perfect for the days to play Mp3 but still even on that PCs we listened to Midi songs.

Therefore if you're one of those people like me who still enjoy to play some Midi Music in the year 2017 and feel a bit like Back into the Future movie and a Free Software fan and user, especially if you're a novice GNU  / Linux Free Software user, you will be unpleasently surprised that most today's default Linux distributions doesn't have an easy way to play Midi music format out of the box right after install.

Hence below article aims to give you an understanding on

How you can play Midi Music on GNU / Linux Operating System

First, lets Prepare to load necessery Linux kernel modules to make sure MIDI can be played by soundcard:

In /etc/modules make sure you have the following list of modules loaded:
 

linux-desktop:~# cat /etc/modules
3c59x
snd-emu10k1
snd-pcm-oss
snd-mixer-oss
snd-seq-oss

!Note the modules are working as of time of writting and in time can change to some other modules, depending on how the development of ALSA (Advanced Linux Sound Architecture) goes, and if the developers decide to rename the upmentioned modules

If you just have added the modules to /etc/modules with vim / nano to reload modules into the Linux kernel run:

 

linux-desktop:~# modprobe -a


Secondly, Installing a whole bunch of MIDI music related program tools can be achieved in Debian by installing the multimedia-midi package, e.g.:

 

linux-desktop:~# apt-get install –yes multimedia-midi

 

1. Playing Midi in Graphical environment with a double click using VLC


How to make MIDI easy listanable in Linux graphical environment like GNOME / KDE / XFCE desktop ?

 

If you want to make Midi music execution sa easy as  just clicking on the .MIDI file format on Linux you can do that with a midi extension available for VLC (Video Lan Client) Universal Multi Platform Media Player player

To install it on Debian Ubuntu GNU / Linux
 

# apt-get install –yes vlc-plugin-fluidsynth

 

Необходимо е да се изтеглят 6754 B архиви.
След тази операция ще бъде използвано 35,8 kB допълнително дисково пространство.

Besides making your MIDI play on the GUI environment easy as a a point and click VLC will also be able to play MIDIs on GNU / Linux from your favourite browser (nomatter Firefox / Chrome or Opera), even though the player would play in a new PopUP Window it is easy to select once MIDI file from a random website for example – here is a directory listing of Webserver with Doom II Soundtrack in MIDI format , click over any file from list and Choose option for VLC to always remember that MIDI files has to be opened with VLC player.
 


2. Enable Firefox / IceWeasel browser to Support Website embedded MIDI files

 

 

So VLC could make you listen the downloadable MIDIs from Web pages but,
 

What if you have stumbled onan old website which was configured with very OLD HTML Code to play some nice music (or even different MIDI songs) for each part of the website (for each webpage) and you want to have the Websites created with embedded MIDIs to automatically play on Linux oncce you visit the site?


Sadly default support in Browser for MIDI across all GNU / Linux, I've used so far never worked out of the box, not that still anyone is developing modern websites with MIDIs, but still for the sake of backward compitability and for sake of interactivity it is worthy to enable embedded MIDI support in Linux

But with a couple of tunings as usual GNU / Linux can do almost everything, so here is how to enable embedded browser support for Midi on Linux (That should work with minor modifications not only on Debian / Ubuntu / ArchLinux but also on Fedoras, CentOS etc.
If you try it on any of this distributions, please drop a short comment and tell me in few lines how you made embedded midi worked on that distros.

 

apt-get install –yes timidity mozplugger

Next do restart firefox

Sometimes in order to work you might need to delete /home/[YOUR_USERNAME]/.mozilla/pluginreg.dat and restart firefox again, e.g. make a backup and give it a try:

 

cp -rpf /home/hipo/.mozilla/pluginreg.dat /home/hipo/.mozilla/pluginreg.dat.bak
rm -f /home/hipo/.mozilla/pluginreg.dat

 

Another good tip as talking for embedding MIDI support is to embed XPDF to render PDF pages inside the Browser, by default this is done by GNOME's Evince PDF reader but as it is sometimes buggy and might crash it is generally a good idea to switch to xpdf instead, if for some reason PDF is not directly displaying in browser or suddenly stopped working after some distro uipgrade, you might want to do below as well:
 

apt-get install xpdf

vim /etc/mozpluggerrc

Fin d and Comment out the line starting with:

It should look like this afterwards:

 Repeat Swallow ….
 

text/x-pdf: pdf: PDF file
#      repeat swallow(documentShell) fill: acroread -geometry +9000+9000 +useFrontEndProgram "$file"
        repeat noisy swallow(Xpdf) fill: xpdf -g +9000+9000 "$file"
        repeat noisy swallow(gv) fill: gv –safer –quiet –antialias -geometry +9000+9000 "$file"


 

3. Play Midi music in Linux text console / terminal


There is a console tool that historically has been like the Linux standard for playing midis over the years as I remember, its called timidity

 


To install timidity on .Deb based Linux:
 

linux-desktop:~$ su root
Password:
linux-desktop:~# apt-get install –yes timidity

Необходимо е да се изтеглят 0 B/580 kB архиви.
След тази операция ще бъде използвано 0 B допълнително дисково пространство.
(Reading database … 382981 files and directories currently installed.)
Preparing to unpack …/timidity_2.13.2-40.5_amd64.deb …

Setting up timidity (2.13.2-40.5) …
Processing triggers for menu (2.1.47+b1) …

 

To test your new MIDI Synthesizer tool and make the enjoyment full you can download Doom 2 extracted MIDI Soundtrack from here
 

Once you have downloaded above Metal MIDI DOOM old school arcade soundtrack and untarred it into your home directory be it ~/doom-midis

A remark to make here is timidity is quite CPU intensive, but on modern Dual and Quad-Core PC Notebooks, the CPU load is not of a big concern.

To test and play with timidity:
 

linux-desktop~$ timidity ~/mp3/midis/*


timidity-playing-doom-midi-bunny-song-on-debian-stretch-gnome-terminal-screenshot
 

hipo@jericho:~/mp3/midis$ aplaymidi -l

We have also the playmidi  (simple midi text console terminal player), which historically was working quite decent and I use it to in the past on my RedHat 6.0 and RedHat 7.0 to listen to my .MID format files but unfortunately as of time of writting something is wrong with it, so when I try to play MIDIs with it instead of timidity I get this erro:

 

$ playmidi *.mid
Playmidi 2.4 Copyright (C) 1994-1997 Nathan I. Laredo, AWE32 by Takashi Iwai
This is free software with ABSOLUTELY NO WARRANTY.
For details please see the file COPYING.
open /dev/sequencer: No such file or directory

Even though I tried hard to resolve that error by loading various midi related MIDI modules and following a lot of the suggestions online on how to  make /dev/sequencer work again it was all no luck.
 

Some people back in the distant year 2005, reported the problem was solved by simply loading snd-seq

But as of time of writting:

 

# modprobe snd-seq

 

Some people said in archlinux's Forum

/dev/sequencer sequencer: No such file or directory

 

is solved by loading snd-seq-oss kernel module, but on my Debian Linux 9.1 Stretch,this ain't work as well :

 

root@jericho:/home/hipo/mp3/midis# modprobe snd-seq-oss
modprobe: FATAL: Module snd-seq-oss not found in directory /lib/modules/4.9.0-3-amd64
root@jericho:/home/hipo/mp3/midis# uname -a;
Linux jericho 4.9.0-3-amd64 #1 SMP Debian 4.9.30-2+deb9u5 (2017-09-19) x86_64 GNU/Linux


Another invention of mine was to try to also link /dev/snd/seq to /dev/sequencer but this produced no positive result either:

 

# ln -sf /dev/snd/seq /dev/sequencer
# ls -al /dev/sequencer
lrwxrwxrwx 1 root root 12 окт  4 16:48 /dev/sequencer -> /dev/snd/seq


Note that after lining in that way I got following error with my attempt to play MIDIs with playmidi

# playmidi *.mid
Playmidi 2.4 Copyright (C) 1994-1997 Nathan I. Laredo, AWE32 by Takashi Iwai

there is no soundcard


Anyhow on some other Linux distributions (especially with Older Kernel versions), some of the above 3 suggested Fix might work perfectly fine so if you have some time give it a try please and drop me  a comment on how it went, you will help the GNU / Linux community out there that way.

Well never mind the bollocks, so

Now back to where I started timidity even though it will play fine it will not give any indication on the lenght of the midi song (precious information such as how much time is left until the end is over).

Hence if you prefer a player that gives you an indicator on how much is left towards the end length of each of the played MIDI file you can give a try to wildmidi:

 

linux-desktop:~$ apt-cache show wildmidi|grep -i description -A 2

Description-en: software MIDI player
 Minimal MIDI player implementation based on the wildmidi library that
 can either dump to WAV or playback over ALSA. It is intended to

If yet not installed install it after becoming admin user:

 

linux-desktop:~$ su root

linux-desktop:~# apt-get install –yes wildmidi


wildmidiis much less CPU intensive (it uses gstreamer to play (Gstreamer – open source multimedia framework)

And next give it a try by running:

 

linux-desktop:~$ wildmidi ~/mp3/midis/*

4. Editting MIDI files with Free Software and Proprietary MIDI Editor Programs

 


If you want a professional software that can play Midi in a fuzzy interactive GUI way and have some extra possibilities to edit MIDIs and other format give a try to Muse Sequencer:
 

 

linux-desktop:~$ sudo apt-get install –yes muse

5. Some examples for Text editing and MIDI Conversion to CSV and ABC file formats There is pretty much more

For the MIDI Extremists who or people that create MIDIs and want to learn how a MIDI is made (the content of it etc.), I suggest you take a look at these 3 command line MIDI editing / conversion tools
 

  • midi2abc – A little tool to create MIDI formats to ABC format
  • midi2csv – Conver tour Favourite MIDI files to CSV for educational purposes so see what Channels, Tracks and Time Intervals is a MIDI song mad
  • midicopy – Copy selected, track, channel, time interval of MIDI file to another MIDI file3

 

Well, that's all folks now enjoy your MIDIs and don't forget to donate, as I'm jobless at the moment and the only profit I make is just a few bucks out of advertisement on this blog.
 

Currency converter Free Desktop Software for Microsoft Windows

Saturday, December 8th, 2012

Reading Time: 2minutes

Business or not a business entity, in the mostly globalized world it is almost inevitable to go on at least monthly basis without a need for some kind of currency convertion. Of course there are plenty of websites allowing Free Money Convertion services out there. However as I'm not a big fan of the Software as a Service (SAS). I don't like other people to be able to sniff what kind of money, amounts I'm intending to convert as well as I don't like google or other search engine to profile me how frequently I'm converting or intending to convert money. Thus today I did a quick research what kind of Free and  Open Source Software FOSS is available to do the money convertion operation custom on my own webserver or my desktop PC. Though It was not exactly what I was looking for I found a Windows Desktop Software -CConverter which is capable of convertions between mostly if not all Currencies around the world. I'm not a m$ Windows user myself, but I was glad to know a Free Software exists for the task. CConverter is definitely a piece of soft useful for Businesses and People. In future if I do my own business it would be nice to know of this little handy soft existence and I will put it in action (to save costs) and add confidentiality to my business money transaction / convertions. Below is the two screenshots of CConverter I found on the project's sourceforge website:

GNU and Free Software founder Richard Stallman tries to peacefully protest European software Patents – Is european Union really democratic?

Friday, July 13th, 2012

Reading Time: 2minutes

rms-sign-peacefully-protests-anti-freedom-EU-legislation

Richard Stallman the main person thanks to whom the GNU (GNU is not UNIX) organization, free software as we know it and GNU / Linux free operating system exists has been notable for being a pain in the ass for politicians. RMS has dedicated his life for the only goal to propagate his ideas that all computer software should be free as in freedom. He is known to have engaged in various petitions and peaceful protest events as well doing his best to raise awareness in people that our Freedoms as we know it are large endangered due to a daily introduced laws throughout the world aiming to limit us and take away our constitutional (democratic) freedoms.

In his lectures RMS at many times puts his thoughts on the lack of real democratic decision taking in the European Union.

A good example on how un-democratic the EU is a Software Patent session being held in Brussels just a a year ago. The Software patent session is officially said to be opened, (so anyone from the public) can participate. What is really weird about the whole thing is that an European institution is trying to campaign a software patents to be legislated in Australia. Hmm isn't that weird, wasn't the European Union to be mainly engaged in minding for the European member countries and european economy or software situation. Why on earth they try to in-force software patents in Australia if Australia has nothing to do with the EU. Didn't the EU has enough problems already caused by patenting … The patent session held was completely "bribed" as Stallman points out, the people attending was "computer specialists" and patent experts who were all only  in favor of software patents and there was no practical representative of any tech-expert who was not in favour of software patents. Stallman tried to peacefully protest the unwalful meeting by just holding a big signature saying  "NO TO SOFTWARE PATENTS". He entered the hall and tried to stay in the back of the room with the NO SOFTWARE PATENTS slogan without even saying a word. A short after a policeman come and took him away for no apparent reason, obviously showing that peaceful protesting to any of what the EU is lobbying about is no longer possible. Now how this is a democracy and how comes the European Union is proclaiming being democratic if even a peaceful protesting of someone or bunch of people opposing an idea, agenda or meeting can't take place?

Do you know that you use GNU / Linux on work at home everyday?

Friday, April 6th, 2012

Reading Time: 2minutes

Do you know you use GNU / Linux unknowingly everyday. I bet you didn't 🙂 While reading my daily sites among which is Linux Weekly News

I came across a very interesting video which the Linux Foundation created. The video is quite nice to see. It has a bit of a technical mambo jambo which ordinary "non-englightened computer" user will not understand completely, however the main message is quite clear. The video displays, how everyday by using Google Facebook, Wikipedia, Amazon  and many other Web based services.
You untentionally become a Linux user 🙂

There is almost no person among the developed nations that doesn't have access to the internet already. Facebook already has about a billion of users the computer internet users are more than 1/3 of all the population more than 2 billion as of time of writting this post

The internet has already completely revolutionized our lives and it continues doing it. The rapid development of the internet was also more or less achieved thanks to GNU / Linux and free software which enabled non programmers to use cheap and affordable software to build tremendous Software As a Service Systems (SASS) as most of the free email services, search engines, photo sharing services, blogs you name it.

From the desktop computers Linux and plenty of free software has moved to the Mobile platforms, where it ruled the market similar to the server market. Nowdays anyone who owns android phone is running some kind of modification of the Linux kernel. MeeGOGoogle Phone and other "open" mobile phone architectures are more and more ruling the mobile market. Linux is also widely used along a lot of other critical services in critical information data systems like in Governments, Railway stations, Global Markets, Stock Exchange platforms, the list goes on and on. Some of the other areas Linux is heavily used is in National Security, Mobile networks, High End servers, police stations etc. etc.
The rate of adoption of Linux is steadily increasing day by, day and this is not strange since it is completely free to use by anyone for everything he might imagines.

Must have software on freshly installed windows – Essential Software after fresh Windows install

Install-update-multiple-programs-applications-at-once-using-ninite

If you're into IT industry even if you don't like installing frequently Windows or you're completely Linux / BSD user, you will certainly have a lot of friends which will want help from you to re-install or fix their Windows 7 / 8 / 10 OS. At least this is the case with me every year, I'm kinda of obliged to install fresh windowses on new bought friends or relatives notebooks / desktop PCs.

Of course according to for whom the new Windows OS installed the preferrences of necessery software varies, however more or less there is sort of standard list of Windows Software which is used daily by most of Avarage Computer user, such as:
 

I tend to install on New Windows installs and thus I have more or less systematized the process.

I try to usually stick to free software where possible for each of the above categories as a Free Software enthusiast and luckily nowadays there is a lot of non-priprietary or at least free as in beer software available out there.

For Windows sysadmins or College and other public institutions networks including multiple of Windows Computers which are not inside a domain and also for people in computer repair shops where daily dozens of windows pre-installs or a set of software Automatic updates are  necessery make sure to take a look atNinite

ninite-automate-windows-program-deploy-and-update-on-new-windows-os-openoffice-screenshot

As official website introduces Ninite:

Ninite – Install and Update All Your Programs at Once

Of course as Ninite is used by organizations as NASA, Harvard Medical School etc. it is likely the tool might reports your installed list of Windows software and various other Win PC statistical data to Ninite developers and most likely NSA, but this probably doesn't much matter as this is probably by the moment you choose to have installed a Windows OS on your PC.

ninite-choises-to-build-an-install-package-with-useful-essential-windows-software-screenshot
 

For Windows System Administrators managing small and middle sized network PCs that are not inside a Domain Controller, Ninite could definitely save hours and at cases even days of boring install and maintainance work. HP Enterprise or HP Inc.Employees or ex-employees would definitely love Ninite, because what Ninite does is pretty much like the well known HP Internal Tool PC COE.

Ninite could also prepare an installer containing multiple applications based on the choice on Ninite's website, so that's also a great thing especially if you need to deploy a different type of Users PCs (Scientific / Gamers / Working etc.)

Perhaps there are also other useful things to install on a new fresh Windows installations, if you're using something I'm missing let me know in comments.

Happy Sysadmin day! – Last Friday of July – The day of the system administrator

Its-SysAdminDay-SAD-day-the-day-of-the-system-administrtator-cake-hooray

Every Last Friday of July is System Administrator's day. This relatively new technocrat tradition started as suggested by the system administrator Ted Kekatos in 2000.

SysAdmin Day or (SAD) 🙂 as it is also famous is a day to appreciate the achieviments of anyone seriously involved in IT industry.Now is time to say SAD day is not a day for programmers to celebrate as there is separate Programmer's day / Day of the Programmer feast or (DOP / DOPE ) 🙂 that is celebrated on the 256th (hexadecimal 100th, or the 28th) day of each year (September 13 during common years and on September 12 in leap years).

System Administrator Appreaciation Day – (SAAD) was historically inspired by Hewlett Packardmagazine advertisement in which a system administrator is presented with flowers and fruit-baskets by grateful co-workers as thanks for installing new printers.

 

DOPE's started as proposed by Valentin Balt and Michael Cherviakov, employees of Parallel Technologies (a software company). In 2002, they tried to gather signatures for a petition to the government of Russia to recognize the day as the official programmers' day.


The modern usual way to celebrate Sysadm day is to get your system administrator a day. If you're at poisition to administrate a couple of hundreds of Windows hosts, you can send a prank message to your colleagues reminding them to buy you a beer or mass mail / set a Outlook Meetingreminder that system administrators – doesn't drink flowers and chocolate 🙂

 

A Day In The Life Of A SAN Administrator

Since 2000, a lot of UNIX / Linux sysadmins and  geeks tend to organize gatherings and Free Software celebration meetings on the SAD day.

SysAdminDay has inspired plenty of other pranky novels and music to glorify the remarkable event 🙂

Here are few to cheer you up.

How to password encrypt / decrypt files on Linux to keep and pass your data private

Thursday, August 7th, 2014

Reading Time: 3minutes

how-to-password-protect-encrypt-decrypt-files-linux-tux-logo.png
If you have a sensitive data like a scan copy of your ID card, Driving License, Birth Certificate, Marriage Certificate or some revolutionary business / idea or technology and you want to transfer that over some kind of network lets say Internet vie some public unencrypted e-mail service like (Gmail.com / Yahoo Mail / Mail.com / (Bulgarian Mail Abv.bg)) etc. you will certainly want to transfer the file in encrypted form to prevent, someone sniffing your Network or someone having administrative permissions to servers of free mail where your mail data is stored.

Transferring your files in encrypted form become very important these days especially after recent Edward Snowden disclosures about American Mass Surveilance program PRISM – for those who didn't yet hear of PRISM (this is a American of America's NSA – National Security Agency aiming to sniff and log everyone's information transferred in digital form via the Internet and even Mobile Phone conversations)…

First step to mitigate surveilance is to use fully free software (100% free software) OS distribution like Trisquel GNU / Linux.
Second is to encrypt to use encryption –  the process of transforming information (referred to as plaintext) using an algorithm (called cipher) to make it unreadable to anyone except those possessing special knowledge, usually referred to as a key.
There are many ways to encrypt your data on Linux and to later decrpyt it, I've earlier blogged about encryping files with GPG and OpenSSL on Linux, however encryption with GPG and OpenSSL is newer as concept than the old-school way to encrypt files on UNIX with crypt command which in Linux is replaced by mcrypt command.

mcrypt is provided by mcrypt package by default on most if not all Linux distributions, however mcrypt is not installed by default so to start using it you have to install it first.

1. Install mcrypt on Debian / Ubuntu / Mint (deb based) Linux

apt-get install –yes mcrypt

 

2. Install mcrypt on Fedora / CentOS rest of RPM bases Linux

yum -y install libmcrypt

 

3. Encrypting file with mcrypt

To get a list with all supported algorithms by mcrypt:
 

mcrypt –list
cast-128 (16): cbc cfb ctr ecb ncfb nofb ofb
gost (32): cbc cfb ctr ecb ncfb nofb ofb
rijndael-128 (32): cbc cfb ctr ecb ncfb nofb ofb

Enter the passphrase (maximum of 512 characters)
Please use a combination of upper and lower case letters and numbers.
Enter passphrase:

If crypt is invoked to create the encrypted file without OS redirects (< >), i.e.:
 

mcrypt -a blowfish File-To-Crypt.PDF

Please use a combination of upper and lower case letters and numbers.
Enter passphrase:
Enter passphrase:

File File-To-Crypt was encrypted.

 


mcrypt outputs encrypted file in .nc extension and the new file and file default mode of 0600 (read write only for root user) are set, while new file keeps the modification date of the original.


4. Decrypting file with mcrypt

Decryption of files is done mdecrypt

mdecryptFile-To-Crypt.PDF.cpy
 

Enter passphrase:
File File-To-Crypt.PDF.cpy was decrypted.

To make mcrypt behave in a certain way when invoked modify ~/.mcryptrd

mcrypt is also available as a module for php5 (php5-mcrypt).
