Some free software for Windows

Here is a list of popular free software applications that run on Microsoft Windows — along with the proprietary applications they replace. If you are still a Windows user, you can take a first step towards free software by installing these applications.

When we say these application programs are free software, we're talking about freedom, not price. It means that you are free to use these programs constructively, either alone or in a community, while respecting the freedom of others. The source code is available, so that you can study the software, adapt it to your needs, fix bugs, and release versions with new features. You can also convince or pay others to do these things for you. You are also free to give away and free to sell copies, under the terms of the applicable free software license. These programs are free software because you have freedom in using them. Free software develops under the control of its users.

Microsoft Windows is a clear and instructive example of nonfree software. Its source code is a secret, so programmers cannot learn from it, fix it, adapt it to their clients (your) needs, or even verify what it really does. If you share copies with your neighbors, you will be called a "pirate", and users have been threatened with imprisonment for this. Nonfree software is completely controlled by its developer, who also has power over the users.

Using free software on Microsoft Windows (or any nonfree operating system) is the first step towards freedom, but it does not get you all the way there. You're still under Microsoft's power as long as you use Windows.

So the next step is to replace Windows with a free operating system such as GNU/Linux.

However, on this page we're concerned with the first step.

Blender 3D

Replacement for: Maya, 3DSMax

Blender is the first and only fully integrated 3D graphics creation suite allowing modeling, animation, rendering, post-production, realtime interactive 3D and game creation and playback with cross-platform compatibility.

Dia

Replacement for: Microsoft Visio

Dia is designed to be much like the proprietary Microsoft program 'Visio'. It can be used to draw many different kinds of diagrams. It currently has special objects to help draw entity relationship diagrams, UML diagrams, flowcharts, network diagrams, and simple circuits. It is also possible to add support for new shapes by writing simple XML files, using a subset of SVG to draw the shape.

It can load and save diagrams to a custom XML format (gzipped by default, to save space), can export diagrams to EPS or SVG formats and can print diagrams (including ones that span multiple pages).

Pidgin

Replacement for: Trillian, AIM, MSN, Yahoo and ICQ chat clients

Pidgin (gaim) is a multi-protocol instant messaging client, with support for:

• AIM (Oscar and TOC protocols),
• ICQ,
• MSN Messenger,
• Yahoo,
• IRC,
• Jabber,
• Novell,
• Gadu-Gadu, and
• Zephyr networks.

Pidgin also supports plugins, for additional functionality.

GIMP

Replacement for: Photoshop, Paint Shop Pro

GIMP is an acronym for GNU Image Manipulation Program. It can be used as a simple paint program, an expert quality photo retouching program, an online batch processing system, a mass production image renderer, an image format converter, etc.

GIMP is expandable and extensible. It is designed to be augmented with plug-ins and extensions to do just about anything.

Anyone who is familiar with the GNU/Linux operating system has probably seen/used the GIMP at some stage. In terms of compatibility, GIMP can open/manipulate the PhotoShop PSD format and the Paint Shop Pro PSP format.

GNUnet

Replacement for: Napster, etc.

GNUnet is a framework for secure peer-to-peer networking that does not use any centralized or otherwise trusted services. A first service implemented on top of the networking layer allows anonymous censorship-resistant file-sharing. GNUnet uses a simple, excess-based economic model to allocate resources. Peers in GNUnet monitor each others behavior with respect to resource usage; peers that contribute to the network are rewarded with better service.

Inkscape

Replacement for: Adobe Illustrator, Macromedia Freehand, CorelDraw or Xara Xtreme Inkscape is an vector graphics editor, with capabilities similar to Illustrator, Freehand, CorelDraw, or Xara Xtreme using the W3C standard Scalable Vector Graphics (SVG) file format. Supported SVG features include shapes, paths, text, markers, clones, alpha blending, transforms, gradients, patterns, and grouping.

Inkscape also supports Creative Commons meta-data, node editing, layers, complex path operations, bitmap tracing, text-on-path, flowed text, direct XML editing, and more. It imports formats such as JPEG, PNG, TIFF, and others and exports PNG as well as multiple vector-based formats.

MinGW

Replacement for: Microsoft Visual C++

MinGW (Minimalist GNU for Windows) provides many of the GNU programming utilities on Windows. It includes the GNU Compiler Collection (GCC), Binutils, Gnu Debugger (GDB), make, and more.

Application:

Mozilla Thunderbird

Replacement for: Outlook, Outlook Express

Versatile and modular e-mail client. Supports themes and extensions to customise and increase its functionality. Has integrated "smart" spam filter, to cut down significantly on spam mail. Also integrates (via EnigMail extension) seamlessly with GNU GPG.

LibreOffice

Replacement for: Microsoft Office

LibreOffice is a multi-platform office productivity suite compatible with all major file formats.

Scribus

Replacement for: PageMaker, InDesign, QuarkXPress

Scribus is a desktop publishing application, like Adobe PageMaker or Adobe InDesign from the proprietary software world. It is free software, distributed under the terms of the Gnu General Public License.

Scribus supports many major graphic formats including most all of the standard ones used in DTP in addition to SVG import and export.

VideoLAN Client (VLC)

Replacement for: Windows Media Player, PowerDVD

VLC (initially VideoLAN Client) is a highly portable multimedia player for various audio and video formats (MPEG-1, MPEG-2, MPEG-4, DivX, mp3, ogg, ...) as well as DVDs, VCDs, and various streaming protocols. It can also be used as a server to stream in unicast or multicast in IPv4 or IPv6 on a high-bandwidth network.

This is a selection of the more common free software applications available for the Microsoft Windows platform, and is nothing like a comprehensive list.

Some free software for Windows

Free GNU-Linux distributions

Following are the GNU/Linux distributions I know of which have a firm policy commitment to only include and only propose free software. They reject non-free applications, non-free programming platforms, non-free drivers, or non-free firmware “blobs”. If by mistake they do include any, they remove it. To learn more about what makes for a free GNU/Linux distribution, see Guidelines for Free System Distributions.

If you're wondering why a certain popular distribution isn't listed here, you may want to check  this page thta explaining why gnu.org don't endorse some common distributions.

Some distributions are making efforts to move toward a completely free system. We thank them for their ongoing work to achieve that goal, and hope to list them here some day.
Information about individual GNU packages (most of which are included in the free distros here) is available separately.
All of the distributions that follow are installable to a computer's hard drive and most can be run live. They are listed in alphabetical order.

Distribution	Description
	BLAG Linux and GNU, a GNU/Linux distribution based on Fedora.
	Dragora, an independent GNU/Linux distribution based on concepts of simplicity.
	Dynebolic, a GNU/Linux distribution with special emphasis on audio and video editing.
	gNewSense, a GNU/Linux distribution based on Debian and Ubuntu, with sponsorship from the FSF.
	Musix, a GNU+Linux distribution based on Knoppix, with special emphasis on audio production.
	Parabola GNU/Linux, a distribution based on Arch that prioritizes simple package and system management.
	Trisquel, a GNU/Linux distribution oriented toward small enterprises, domestic users and educational centers.

New gTLDs - The Next Generation of domain names

Ever since its inception, the Internet has been evolving, and with the recent announcement of the New Global Top Level Domains (New gTLDs) by ICANN, it will soon be possible to get your very own TLD. Unlike traditional domain names, such as example.com, the domain name is always preceded by a TLD extension, such as .com .
The New gTLD is very different to traditional domain names, and by registering your very own gTLD, you could register your brand, product, service, region or name in the top level name space.


Just imagine a domain name such as:

• .you
• .yourlocation
• .yourbrand
• .yourservice
• .yourproduct
• .yourregion
• .yourclub
• .yourname

Now is your chance to become one of the first to apply for your own New TLD. According to the most recent revision of the ICANN gTLD Guidebook, the New gTLD domain names applications will be accepted under the following categories:

• GENERIC
• BRAND NAME / TRADE NAME / TRADEMARK / REGISTERED TRADEMARK
• GEOGRAPHIC REGION

The New gTLDs will also provide you with the option of registering your TLD using both the traditional Latin based characters (English Characters), or in the IDN (Internationalized Domain Name) format. This means your TLD can be used to target a specific demographic.

New gTLD Timeline

The New gTLD has been a work in progress. ICANN intend to launch the New gTLD program at the ICANN Conference held in Singapore in June 2011. This time line is a visual representation of the time required for a gTLD application to be registered into a Top Level Domain (TLD).



Final Approval of the ICANN Guidebook (June 2011)

We are now in this period, and ICANN are in the final stages of publishing the final New gTLD Guidebook. Once formally approved, it is expected that ICANN will announce the roll out of the New gTLD program at the ICANN Conference in Singapore.



Communication Period / Application Window Period (June 2011 to March 2012)

This period represents the time that ICANN will accept the first 500 initial gTLD applications for the New gTLD program.



gTLD Applications Publicly Announced (Expected March 2012)

This period is when ICANN will publicly announce the gTLD applications they have received. This is necessary to allow for third parties to place objections to any specific gTLD application.



Public Registration of gTLD (Expected October 2012)

This period represents the first registration of the New gTLDs, and the delegation of the New gTLDs into the live DNS. This period also represents a new era of the Internet and Domain Names, and it will be recognized as a major milestone of the evolution of the Internet.

Why should I get a New gTLD?

There are many advantages to getting your very own gTLD. Having your very own gTLD provides you with greater brand awareness and protection, and as you become the top level administrator of your TLD, you have the added benefit of Securing your name, giving you the peace of mind.

• 
  
  GREATER BRAND AWARENESS AND BRAND PROTECTION
  For serious business, using a New gTLD is the ultimate way of establishing your online brand and protecting your brand, and ensuring that your brand is recognized at the top level. Having your very own TLD ensures that:
  
  • Your brand is visible at the highest level
  • Your brand becomes a physical web address at the URL level
  • It promotes consumer trust in your brand
  • It provides you with the unlimited marketing opportunities
  • It will become recognized as a sign of authority
  • Global Exposure to a Global Audience
• 
  
  SECURITY AND PEACE OF MIND
  Fraudulent activities such as phishing and malware scams is the cause of many unwanted problems for Internet based businesses. Being a victim of such scams can permanently effect the reputation of your business.
  
  Using your very own gTLD, you can control the way that your TLD is managed, you can choose to permit or deny registrations in your own name space, and you can build your online business around your own TLD. When you have your own TLD, you can build trust in your online presence as a safe and secure domain name – because you are the master of your domain.
  
• 
  
  PROVEN TRACK RECORD
  Instra recognizes that reliability, security, monitoring are essential to ensure that any registry system remains stable.
  
  
  Instra has a proven track record in providing registry services for domain names and ENUM. We understand the importance of providing a proven and stable registry service, and being able to back that up with a robust and reliable IT infrastructure. Our global network has been designed and developed to ensure that your TLD continues to work – regardless of what events are happening around the world.
  
• 
  
  BE THE FIRST TO APPLY AND SECURE YOUR NAME
  It is expected that the new gTLD launch will be rolled out in several phases. Unlike traditional domain names, successful gTLD applicants within the initial application stage will have an approximate three year lead over competitors who decide to apply during the subsequent phases. Unlike other domain names, there will be no After Market program, so once a keyword has been registered, it will be gone forever.
  

The pending launch of the new gTLD will change the Internet forever. Do not miss out on this limited opportunity, and Register your Expression of Interest today.

Ce trebuie să ştiţi despre reţelele wireless

Ce sunt comunicaţiile în reţea wireless?

Cum poate utiliza compania dvs. comunicaţiile în reţea wireless

Noţiuni introductive privind reţelele wireless

Ce sunt comunicaţiile în reţea wireless?

Activităţile de afaceri părăsesc biroul şi se mută în sala de conferinţe, în secţia de producţie, în automobil, la domiciliu, la aeroport, la hotel şi la restaurant. Pentru a beneficia de această libertate, companiile mici utilizează reţele wireless şi hotspot-uri WiFi pentru a rămâne în contact cu angajaţii, clienţii şi partenerii.

O reţea locală (LAN) wireless vă permite să conectaţi computerele fără a avea nevoie de fire sau cabluri. Aveţi nevoie de un document de pe server când sunteţi în sala de conferinţe? Doriţi să accesaţi sistemul de stocuri din depozit? O reţea wireless facilitează acestea utilizând unde radio pentru a permite dispozitivelor mobile dintr-o numită zonă să se conecteze şi să comunice.

Avantajele comunicaţiilor wireless

Avantajele reţelelor wireless sunt atât pe termen scurt, cât şi pe termen lung:

• Comoditate. În prezent, toate notebook-urile şi numeroase telefoane mobile sunt echipate cu tehnologie WiFi pentru conectare directă la o reţea LAN wireless. Angajaţii pot accesa securizat resursele reţelei dvs. din orice locaţie din zona de acoperire. În general, zona de acoperire de referă la sediul companiei, însă poate include mai multe clădiri.
• Mobilitate. Angajaţii pot rămâne conectaţi la reţea chiar dacă nu lucrează din birourile proprii. Persoanele care participă la întruniri pot accesa documente şi aplicaţii. Agenţii de vânzări pot accesa reţeaua din orice locaţie pentru a consulta informaţii importante.
• Productivitate. Accesul la informaţii şi la aplicaţiile principale ale companiei ajută angajaţii să îşi ducă la bun sfârşit activităţile şi încurajează colaborarea. Vizitatorii (clienţi, furnizori sau producătorii) pot beneficia de acces securizat pentru invitaţi la Internet şi la datele de afaceri proprii.
• Configurare simplă. Atunci când nu necesită montarea de cabluri, instalările pot fi rapide şi rentabile. De asemenea, reţelele LAN wireless facilitează conectarea locaţiilor greu accesibile, de exemplu depozite sau secţii de producţie.
• Scalabilitate. Pe măsură ce operaţiile din cadrul afacerii se dezvoltă, este posibil să trebuiască să vă extindeţi rapid reţeaua. În general, reţelele wireless se pot extinde cu echipamentele existente, în timp ce o reţea cablată poate necesita cablări suplimentare.
• Securitate. Controlarea şi administrarea accesului la reţeaua dvs. wireless sunt importante pentru succesul acesteia. Evoluţiile tehnologiei WiFi asigură protecţii de securitate robuste pentru ca datele dvs. să fie uşor disponibile numai pentru persoanele cărora le permiteţi să le acceseze.
• Costuri. Funcţionarea unei reţele LAN wireless poate avea costuri mai reduse, fapt care elimină sau reduce costurile pentru mutarea, reconfigurarea sau extinderea birourilor.

Cum poate utiliza compania dvs. comunicaţiile în reţea wireless

Într-o companie mică, fiecare minut contează. Reţelele wireless sunt un instrument puternic pentru sporirea productivităţii şi încurajarea partajării de informaţii. Beneficiind de acces nerestricţionat la documente, e-mailuri, aplicaţii şi alte resurse de reţea, angajaţii pot călători oriunde este necesar având acces constant la instrumentele necesare îndeplinirii sarcinilor de serviciu.

Iată câteva modalităţi prin care afacerile pot beneficia de avantajele oferite de reţelele LAN wireless:

Mobilitate şi colaborare sporite

• Călătoriţi fără a pierde conectivitatea
• Conlucraţi mai eficient

Angajaţii care utilizează reţeaua dvs. LAN wireless îşi pot desfăşura activităţile în alte locaţii decât biroul propriu fără a îşi pierde conectivitatea. Imaginaţi-vă cum poate avea fiecare angajat care participă la o întrunire a echipei sau la miniconferinţe acces la comunicaţii imediate şi la toate documentele şi aplicaţiile din reţeaua dvs. În mod similar, utilizând tehnologia Voice over Wireless LAN, angajaţii pot beneficia de capabilităţi de roaming în comunicaţiile lor de voce.

Viteză de reacţie îmbunătăţită

• Conectaţi-vă la informaţiile necesare atunci când aveţi nevoie de ele
• Oferiţi clienţilor servicii îmbunătăţite

Clienţii doresc răspunsuri rapide la solicitările şi problemele lor. O reţea wireless poate îmbunătăţi serviciile furnizate clienţilor prin conectarea angajaţilor dvs. la informaţiile de care aveţi nevoie. De exemplu, un doctor dintr-un cabinet medical poate accesa online fişele pacienţilor în timp ce se deplasează între sălile de consultaţii sau un agent de vânzări poate verifica stocul disponibil necesar pentru completarea de comenzi la o expoziţie comercială.

Acces îmbunătăţit la informaţii

• Conectaţi locaţiile greu accesibile
• Îmbunătăţiţi procesele de afaceri

Reţelele LAN wireless permit companiilor să aducă accesul la reţea în zone dificil de conectat la reţele cablate. De exemplu, adăugarea de puncte de acces wireless la un depozit poate facilita verificarea şi gestionarea stocurilor, asigurând companiei valori precise de inventar în timp real.

Extindere mai uşoară a reţelei

• Adăugaţi rapid utilizatori
• Dezvoltaţi reţeaua în condiţii de rentabilitate

Companiile care trebuie să angajeze personal sau să reconfigureze birourile frecvent vor beneficia imediat de flexibilitatea asigurată de reţelele LAN wireless. Birourile pot fi mutate şi se pot adăuga angajaţi la reţea fără eforturile şi costurile necesitate de instalarea de cabluri şi fire.

Acces pentru invitaţi îmbunătăţit

• Oferiţi clienţilor şi partenerilor de afaceri acces securizat la reţeaua dvs.
• Oferiţi un serviciu cu valoare adăugată

O reţea wireless permite companiei dvs. să asigure acces wireless securizat la Internet pentru invitaţi – clienţi sau parteneri de afaceri. Firmele de retail, restaurantele, hotelurile şi alte afaceri de relaţii cu publicul pot oferi acest acces ca serviciu unic cu valoare adăugată.

Aspecte importante privind reţelele wireless

Odată ce aţi înţeles utilitatea unei reţele LAN wireless pentru afacerea dvs., sunteţi pregătit pentru pasul următor de implementare a proiectului. În continuare vă prezentăm o serie de aspecte de care trebuie să ţineţi cont în această etapă.

Conectarea PC-urilor

Toate computerele notebook şi numeroase PC-uri desktop au integrată tehnologie WiFi şi sunt capabile să acceseze reţeaua dvs. wireless imediat ce aceasta este funcţională. Dacă nu, va trebui să instalaţi pe aceste computere adaptoare wireless – de obicei prin conectare la unul dintre sloturile PCI ale computerelor – sau să vă conectaţi prin intermediul unei reţele LAN cablate.

Starea reţelei existente

Adăugarea unei reţele LAN wireless nu înseamnă renunţarea la reţeaua cablată existentă. Pentru companii este o practică obişnuită să extindă acoperirea reţelelor existente prin crearea de reţele hibride (prin cablu/wireless) care asigură capabilităţi wireless în sălile de conferinţe, în zonele generale de întruniri sau în spaţii noi de birouri. Cu toate acestea, reţelele wireless care acceptă comunicaţii de voce trebuie configurate pentru acoperire mare.

Locaţia punctelor de acces

Acoperirea reţelelor LAN wireless este finită – fiecare punct de acces acoperă până la 280 mp. Acoperirea unui punct de acces poate fi afectată de obstacole precum pereţii şi birourile modulare, iar semnalele radio nu pot penetra zonele metalice, de exemplu puţurile de ascensor. Iată câteva aspecte de care trebuie să ţineţi cont:

• Accesul wireless este partajat şi o regulă empirică stabileşte 15-20 de utilizatori pentru fiecare punct de acces pentru comunicaţii de date şi 8-12 utilizatori pentru fiecare punct de acces pentru comunicaţii de voce.
• Pentru o calitate bună a comunicaţiilor Voice over WLAN, punctele de acces trebuie instalate mai aproape unele de altele
• Intensitatea semnalului wireless se reduce proporţional cu distanţa pe care trebuie să o străbată
• Punctele de acces au o acoperire mai bună atunci când sunt instalate pe plafon

Dezvoltarea reţelei

Unul dintre principalele avantaje ale unei reţele LAN wireless este posibilitatea de adăugare rapidă de utilizatori noi. Asiguraţi-vă că soluţia dvs. wireless este adecvată cerinţelor actuale şi se poate dezvolta odată cu schimbarea cerinţelor. Întrebaţi-l pe furnizorul soluţiei despre uşurinţa implementării de upgrade-uri şi îmbunătăţiri viitoare.

Securitatea

Securitatea într-o reţea wireless este un aspect esenţial şi trebuie să fie o componentă normală la implementarea unei reţele wireless. Iată câteva metode de securizare care trebuie incluse în planul de implementare:

• Criptare a datelor, pentru ca informaţiile să poată fi accesate numai de către utilizatorii autorizaţi
