The home computer

A home computer is a micro computer, which entered the market with the birth of the Altair 8800 on 1975 and extends until the early 1990s. This encompasses almost all 8-bit computers. Commonly used CPUs were the Zilog Z80, MOS Technology 6502 or Motorola 6800 and the first wave of micros equipped with 16-bit CPUs, mainly Motorola 68000 and Intel 8086 and 8088. The term home computer describes from a computer commonly found in the industry and take it home. Excluded from this group are IBM PCs and compatibles.These are called personal computers.

Development

The Altair 8800 was the first home computer but lacked a keyboard and monitor. 1977 saw what the BYTE magazine called the 1977 Trinity and encompassed the Commodore PET, Tandy TRS-80 and Apple 2. They came with a built-in keyboard. The Commodore and Tandy also sported a monitor. Shortly after Atari introduced their 8-bit line of micros. In the United Kingdom computers like the Sinclair ZX 81 and Spectrum as well as the Acorn Atom, better known as BBC Micro, became famous. Many teenager began coding, mainly writing games. They became soon known as bedroom coders. All home computers but the Jupiter ACE had the BASIC programming language built in. The best selling machine was the Commodore 64.

Some types of computers stayed for longer, others evolved trying to maintain compatibility. For example was a Z80 card available for the Apple II as well as for the Commodore 64, opening the huge world of CP/M software for their owners. However, by the end of the 1980s most were eliminated by IBM compatible personal computers and the newer generations of video game consoles because all used their own incompatible formats. The IBM revolution was triggered in 1981 by the output of the IBM 5150 personal computer, the IBM PC.

I got my first micro with the Commodore 64 in 1984. I also had some BASIC knowledge but soon learned to code in 6502 (the C 64 had a 6510 though) assembly language. I soon wanted a Commodore Amiga 500 but waited until 1988 the price came down. After that I only bought IBM compatibles.

American Dad!

American Dad! is an animated television series and adult sitcom created by Seth MacFarlane, Mike Barker and Matt Weitzman for the Fox network. After Fox canceled the show it was picked up from TBS. The series is initially released on February 6th of 2005. American Dad! has been nominated many times, most notably for two Primetime Emmy Awards and two Annie Awards. In June 2013, she was awarded the category of best animated series by the American Society of Composers, Authors and Publishers. Since its first broadcast, the series had more than 200 episodes. In the year 2014 the series passed from the FOX to the TBS network in its eleventh season in September.

Synopsis

The TV show focuses on the Smith family and three other characters with whom they share their lives daily: father and husband Stan Smith is a CIA agent, his wife Francine Smith is a housewife. Their eldest daughter Hayley Smith (voiced by Seth MacFarlane's sister Rachel MacFarlane) and their youngest son, Steve Smith (voiced by Scott Grimes) is a high school student. Apart from the entire Smith family, the series also includes three other main characters, including Hayley's boyfriend and husband Jeff Fischer, the domestic goldfish called Klaus Heissler, actually an East German, trapped in the body of a fish and Roger an alien.

The Smith family resides at 43 Cherry Street in the fictional Langley Falls, Virginia neighborhood. inspired by the city of Langley, Virginia in the United States. The house of the Smiths would seem to be composed of many secret chambers, and many other related and unorthodox pieces seen. The house is also composed of several hatches, including filled with alligators. Greg and Terry are a homosexual couple and neighbors of the Smiths. Steve has three friends. Snot, a Jewish curly-haired teenager, Barry an obese naive and greedy teenager under heavy drug treatment for behavioral problems. And Toshi, a young Japanese who, while understanding English, only talks in Japanese.

My opinion

Almost all episodes follow the same scheme. Like already in Family Guy, somebody of the Smith family goes after another member of the family or friends. There is a fight, struggle and towards the end a reasoning. The situation is usually resolved by saying "I'm (so) sorry" or "I was wrong". And everybody is happy. So predictable. I don't know why I'm still watching this.

How to prevent VOIP Spam

What is SPIT?

Spam over Internet Telephony (SPIT) is telephone spam that is transmitted over the Internet Protocol using IP (Voice over IP) telephony. Telephone spam refers to unwanted telephone calls that are automatically and in large numbers recorded. Phone spam is similar to email spam, but is currently less common and requires other safeguards due to synchronous communication.

How abuse takes place

IP telephony, as well as email and other Internet applications, is prone to being abused by unwanted messages and connections. Call machines can be used for telesales, telemarketers, for alleged winning messages, or as phone calls. In particular, IP telephony offers this freely available software (such as Asterisk or SIP) and inexpensive options to automatically sell a large number of calls. The IP telephony is often based on the Session Initiation Protocol (SIP) [1] for setting up, controlling and reducing the telephone connections. After establishing a SIP session and accepting the call by the called party, a pre-recorded spam message can be recorded. For pure lock or ping calls, no audio data is transmitted.

Large numbers of unwanted and automated phone calls

SPIT is characterized by a large number of unwanted and automated phone calls that are transmitted using the Internet Protocol. The caller (spammer) tries to establish a large number of connections using suitable software and plays a recorded message as soon as the called party answers the call. Using the widely used Session Initiation Protocol (SIP), the connections to INVITE messages are initiated and then configured and set up with other messages; The audio data is then transmitted via the Real-time Transport Protocol (RTP). The spammer can this telephony software such. B. Asterisk use. The spam calls can be transmitted via gateways of the telecommunications network operators in the conventional telephone network (PSTN).

How to prevent VOIP Spam?

Many users have no problem with SPIT already being "shielded" behind NAT or a package filter, AKA firewall. Others, running a Linux server with VOIP server and client on it might be exposed to VOIP Spam. These can protect themselves by setting up one package filter rule:

iptables -A INPUT -p udp ! -s 217.10.79/24 --destination-port 5060 -j REJECT

assuming 217.10/16 is the IP range from your ISP. In this case it's Sipgate. That will throw away all UDP packages to the SIP port (5060, might differ on other setups) unless they come from 217.10.79/24.

How to disable auto play of videos in Chrome and Firefox browsers

When users enter certain web pages, often videos embedded there start to play automatically. Many users, including me, do not wish to run videos they didn't demand. But they play anyway. Is there a way in Browsers like Chrome or Mozilla's Firefox to deactivate the automatic play of videos? Besides it's annoying, these videos use data. When a user has a "cap" with his ISP (the maximal amount of data he can transfer every month) he might pay additional charges for a data transfer, he didn't demand. Luckily for web browser like Mozilla's Firefox and Google's Chrome there is a way, to deactivate the automatic playing of videos, like in Youtube.

Chrome and Chromium web browsers

The Chrome web browser is currently the dominant browser and holds the biggest market share. Thanks to the implementation in Android smart phones and tablets, Android ships.

Desktop

After launching the browser click into the address bar on top and type in about: flags and hit the RETURN key. On top you find a search form. Enter autoplay and click on the first find the drop down menu and choose Document user activation is required. After you restart Chrome videos should not start automatically anymore, but asks the user to confirm, he wants to run a particular video.

Chrome on Android

This is easier. Launch the Chrome browser on your tablet or smart phone and visit Settings and then Site Settings. Scroll down the media menu and select the media tab. There you must select autoplay and click the checkbox, to disable the function.

Mozilla's Firefox

The Firefox browser of Mozilla has some great features. It is highly customizable. It has among other native features the ability, to prevent videos from starting to play automatically. Click the URL bar and type in about:config. Ignore the warning and use the search form to find media.autoplay.default. Set this to "1" if it was not already set. Also find media.autoplay.allow-muted and set this to false. Restart the Firefox browser that the changes take effect

Other methods

If this isn't working for you, third party add-ons come into play. Open the Preferences menu and search for addons or extensions. There is a search form. Search for something like disable, auto play or automatic and install the appropriate extension.

TV series The Orville

The series The Orville is an American TV show created by Seth MacFarlane and premiered on September 10th 2017 on the Fox network in the United States and simultaneously on the Citytv2 network in Canada.

It's a science-fiction drama set in a future, where Earth is part of a larger community of civilizations that coexist in the universe in a peaceful way. The story takes place around a medium-class space ship called Orville and its crew.

Plot

In the 25th century, Earth is part of the Planetary Union with an extended civilization, advanced and above all peaceful and comprises a fleet of approximately 3000 vessels. Among them the Orville, a modern spacecraft led by Captain Ed Mercer (portrait by Seth MacFarlane, the producer of the show), determined to prove his worthiness and to write a new chapter in his life, backed by an eccentric crew.

Cast

Main actors

• Seth MacFarlane as Captain Ed Mercer
• Adrianne Palicki as Commander Kelly Grayson
• Penny Johnson Jerald as Dr. Claire Finn
• Scott Grimes as Lieutenant Gordon Malloy. Scott Grimes was acknowledged in the movie Critters, when he was at the age of fifteen.

Continuity

The first season is considered by fans to be lighthearted, with the focus on jokes similar to these found in Family Guy, which is also produced by Seth MacFarlane. Season two started much darker and had fewer jokes but more blood and killings. Later episodes of season two followed what season one was like.

Crossover between Family Guy and The Orville

Some episodes of Family Guy mentioned The Orville. Many fans of both shows expect that at some point in the near future a crossover between Family Guy and The Orville should take place.

Star Trek references

Some actors from the Star Trek franchise took part in The Orville. Jonathan Frakes and Robert Duncan McNeill already directed episodes of The Orville. While actors like Roberto Picardo (the EMH of Voyager) or John Billingsley, portraying Dr. Phlox in Enterprise or Tim Russ (playing a Vulcan officer onboard the USS Voyager) already had a role in The Orville. Apparently Seth MacFarlane likes to have actors from the Star Trek universe in his show.

War between India and Pakistan

India's Prime Minister Narendra Modi hoped to come out of the election campaign as a strong man. He did not quite succeed. On February 26th 2019 Modi bombed a terrorist camp in Pakistan's Khyber-Pakhtunkhwa province, directly adjacent to the Kashmir mountainous region. He said he responded to a terrorist attack in Kashmir. In the long history of skirmishes between the two countries holding a nuclear stockpile, it was the first time that India did this, thus starting the conflict to escalate.

The cold war between Indian and Pakistan got hotter

Pakistan was unwilling to follow New Delhi's contention that the bombing was an anti-terrorist operation and a non-military preemptive strike. The following day Pakistani military aircraft shot down an Indian fighter plane over Kashmir and took the pilot in captivity. Now the airspace over Pakistan is closed to civilian traffic, because the government expects attacks from India. Thousands of flights have to be diverted worldwide. If this escalates to a war between the two nuclear powers, would it not only have consequences for the South Asian region but the rest of the world.

Dangerous situation

The situation is extremely tense. For the first time in almost 50 years, the air forces of both countries are in direct confrontation. The last war between India and Pakistan took place in 1971 and ended with the defeat of Pakistan and the secession of the state of Bangladesh, formerly East Pakistan.

My opinion

If Narendra Modi wants to respond to a terrorist attack and bomb a camp he should had spoken to the Pakistani president before. Let the Pakistani handle it. Only if Pakistan declined Narendra Modi should tell the Pakistani India will take care of of the situation itself. But as history often shows failure to communicate often leads to disaster. I wonder if Narendra Modi hasn't the brains to not have seen this. Lets pray that if the wage nuclear war there are no strong winds that the fallout falls on their countries only. Both have quite a large landmass.

The Crucible by Arthur Miller

Synopsis

It is 1692 and a town in Massachusetts has an unnerving undercurrent running through it which threatens to tear apart the peace and harmony on which is it based. The undercurrent is that witchcraft is being practiced within the town and with everyone pointing the finger and suspicions at everyone else, the waters are cloudy as to who is actually guilty of the crime. The Salem witch trails start and suddenly everyone's dirty washing is being aired in public.

Strong Characters

The characters involved have been brought to life by Miller to the point that they can be seen on a daily life. Giles Corey is one such example. He is an ageing man, yet one of strong principles and also of integrity although very traditional in nature. He finds it strange and beyond him that his wife reads books, a point that he airs. This then results in his wife being accused of witchcraft. He remains strong to the end in a scene that is quite emotional. Stones are piled onto his chest in a bid for him to confess to practicing witchcraft - if he confesses, he will live but his family cannot inherit his land if so. His reply is constantly "more weight".

A great play with many twists, highlighting the evil trappings of life such and jealously and revenge and showing how a small event can spiral out of control. You cannot say you are a fan of modern plays unless you have seen this! Essential viewing.
