Distributing Code Under GPL Must Not Get Taxed

Sangkrit insists that professional programmers distributing their code under GPL must not get taxed because their business upgrades civilization in a fast forward way.

Software engineers, following the ‘four freedoms’ as taught by Richard Stallman, are free software programmers. Free software programmers, who earn livelihood as taught by Sangkrit, by serving their code to domain registrants under GPL upon getting paid in hourly per terminal basis, are professional programmers. Such source code is eternally left open for further evolution.

Sangkrit insists that professional programmers, distributing their code under GPL, must not get taxed because their business upgrades civilization in a fast forward way. Like Linux kernel under GPL, has built the modern framework of internet age by running most successful operating systems such as GNU and android.

Smart governments should be inventing smarter incentives for freeing the software within their countries since this can improve public life standards without any government investments.

Free Software Effect Had Ascertained The Freedom Of World-Wide-Web

No how less than Linus Benedict Torvalds was influenced at beginning, founder of World-Wide-Web Tim Berners-Lee was also inspired by Richard Matthew Stallman. Very much like the Linux kernel, World-Wide-Web was about to get released under GPL. He made a request to CERN for doing so. Although before CERN made its mind, he himself switched his request on the basis of an afterthought that big corporations such as IBM would become averse to the process due to licensing issues and finally brought it free in public domain like it has been.

It was the free software effect of free software movement that has actually ascertained the freedom of world-wide-web. Indeed RMS left the greatest impact upon digital era, a lot-lot more than most widely used GPL.

Support Keith Curtis To Finish “Software Wars”, A Movie About How We Can All Have Cars That Drive Us Around

Story: The average computer user is unaware there is a war for freedom going on that will determine the path of modern society. Software Wars is a movie about the battle for our right to share technology and ideas.

Network Monitoring With Etherape

EtherApe is a graphical utility that allows you to see in real-time where connections are being made on your network, or between your network or computer and the Internet. If you are experiencing unexpected network activity on your computer or LAN and wish to see where the activity is occurring. Both “local” user and “root user” installations are created; in general you must use the root user installation to see all your network traffic.

sudo apt-get install etherape

Features:

  • Network traffic is displayed graphically. The more “talkative” a node is, the bigger its representation.
  • Node and link color shows the most used protocol.
  • User may select what level of the protocol stack to concentrate on.
  • You may either look at traffic within your network, end to end IP, or even port to port TCP.
  • Data can be captured “off the wire” from a live network connection, or read from a tcpdump capture file.
  • Live data can be read from ethernet, FDDI, PPP, SLIP and WLAN interfaces, plus several other incapsulated formats (e.g. Linux cooked, PPI).
  • The following frame and packet types are currently supported: ETH_II, 802.2, 803.3, IP, IPv6, ARP, X25L3, REVARP, ATALK, AARP, IPX, VINES, TRAIN, LOOP, VLAN, ICMP, IGMP, GGP, IPIP, TCP, EGP, PUP, UDP, IDP, TP, ROUTING, RSVP, GRE, ESP, AH, EON, VINES, EIGRP, OSPF, ENCAP, PIM, IPCOMP, VRRP; and most TCP and UDP services, like TELNET, FTP, HTTP, POP3, NNTP, NETBIOS, IRC, DOMAIN, SNMP, etc.
  • Data display can be refined using a network filter using pcap syntax.
  • Display averaging and node persistence times are fully configurable.
  • Name resolution is done using standard libc functions, thus supporting DNS, hosts file, etc.
  • Clicking on a node/link opens a detail dialog showing protocol breakdown and other traffic statistics.
  • Protocol summary dialog shows global traffic statistics by protocol.
  • Node summary dialog shows traffic statistics by node.
  • Node statistics export to XML file.
  • Scrollkeeper/rarian-compatible manual integrated with yelp.
