Benghazigate versus Bridgegate

Posted by PITHOCRATES - January 16th, 2014

Politics 101

Even though Hillary Clinton lied about Benghazi the Press is more Interested in Bridgegate

The Senate Intelligence Committee released its report on the 2012 attacks in Benghazi.  Surprisingly, or perhaps not surprisingly, actually more of a stating of the obvious, at least for those without their heads up their backsides in blind adoration of President Obama, those who can find no fault with him or his administration no matter how many scandals and lies we catch them in, as their heads are up their aforementioned backsides, the report does not agree with the Obama administration version of what caused this tragedy (see Senate report: Attacks on U.S. compounds in Benghazi could have been prevented by Adam Goldman and Anne Gearan posted 1/15/2014 on The Washington Post).

A long-delayed Senate Intelligence Committee report released Wednesday faulted both the State Department and the intelligence community for not preventing attacks on two outposts in Benghazi, Libya, that killed four Americans, including the U.S. ambassador, in 2012.

The bipartisan report laid out more than a dozen findings regarding the assaults on a diplomatic compound and a CIA annex in the city. It said the State Department failed to increase security at its mission despite warnings, and blamed intelligence agencies for not sharing information about the existence of the CIA outpost with the U.S. military…

The document contains only one mention of then-Secretary of State Hillary Rodham Clinton…

President Obama, Secretary of State Clinton and UN Ambassador Rice all stated publically that the attack in Benghazi was caused by a spontaneous protest over an obscure YouTube video.  They didn’t say it once.  They said it again and again.  It was the YouTube video.  Period.  Which can’t be true if the State Department could have prevented this attack.  For the only way that could have happened was if there were in fact identified security issues that were promptly ignored by the Obama administration.  Not an unknown and unexpected spontaneous protest out of nowhere one day.  So they all lied.  It was planned and coordinated.  And had nothing to do with that obscure YouTube video.

And yet they only mentioned Secretary Clinton once in their report.  Odd considering she failed to do everything she could to protect her people and then lied about it.  You’d think that would warrant more than one mention.  This is big news.  At least you’d think it would be.  But other than a few newspapers and Fox News the media isn’t talking about how Secretary Clinton lied.  Instead they are more interested if another politician lied.  A governor.  In New Jersey.  Who the polls show is the greatest threat against a Hillary Clinton presidency.  They want to know what Chris Christie knew.  When he knew it.  And if he lied about knowing it.

Hillary Clinton’s Incompetence and Indifference to Americans dying doesn’t Interest the Press

They call it Bridgegate.  A play on Watergate.  Something a young Hillary Clinton went after Richard Nixon like a hyena tearing away at the entrails of a fallen prey.  Because Nixon lied.  He knew about a rank amateur burglary after the fact.  And then used the power of the executive branch to try and cover it up.  Much like the Obama administration has done often.  Only Nixon didn’t have a complicit press that would do whatever they could for their dear leader.  But I digress.

Apparently the mayor of Fort Lee, N.J., didn’t endorse Governor Christie in his reelection campaign.  And as payback a couple of Christie’s staffers closed some traffic lanes on the George Washington Bridge to cause the mother of all traffic backups in Fort Lee.  No one died like in Benghazi.  But this is what the press and the Democrats (even the Democrats outside of the press) want to know about.  And some are even using the ‘I’ word.  Impeachment (see Subpoenas Expected for Chris Christie Aides Over Bridge Scandal by GILLIAN MOHNEY posted 1/12/2014 on ABC News).

Legislative subpoenas could be served to the aides of New Jersey Gov. Chris Christie as early as Monday sources told ABC News today.

Christie has been under intense political scrutiny after it was revealed that some of his top political aides shut down key traffic lanes on the George Washington Bridge — the busiest bridge in the world — in September for what appear to be politically motivated reasons…

Some Democratic lawmakers are saying that Christie could face impeachment hearings if it turns out he knew about the lane closures and authorized them.

Wow.  Completely different from the approach in getting answers from Secretary Clinton.  Where when she finally appeared before Congress the Democrats spent more time puckering up and kissing her backside.  And when she said “what difference does it make” if it was her incompetence and indifference to Americans dying or if it was some spontaneous protest where average ordinary Muslims pulled rocket propelled grenades and mortars out of their wallets and purses to storm the American mission in a military assault they applauded her moxy.  Saying, “You go, girl.”  Figuratively, of course.

Without an Independent and Free Press you can’t keep Government Honest

It’s not so much a double standard as it is a biased press.  Much of the mainstream media today is more an extension of the Democrat Party than a free press.  Who spend more time writing propaganda for the left.  Democrats.  Elitists who think like they think.  And know as they know that they are better, wiser and more enlightened than the ignorant masses.  This is why they are foaming at the mouth over Bridgegate.  And ignore Secretary Clinton’s incompetence and indifference over the attack in Benghazi.  She who criticized candidate Barack Obama and his lack of experience.  Saying he wouldn’t know what to do if he got that 3 AM call like she would.  “There’s trouble brewing in Benghazi as we approach the anniversary of 9/11?  Well, what do you want me to do about it?”  Or, perhaps, it was something more like this.  “Tell it to someone who gives a damn.”  Of course it should be noted that this trouble did not start with a 3 AM telephone call.  It was a gradual buildup of trouble that she responded to with incompetence and indifference.

It’s sad what the American press has come to.  Even Britain with her socialist tendencies following World War II at least still has a fierce free press.  That will speak truth to power.  Put their country first instead of puckering up and kissing the backsides of those in the political party they favor.  Ignoring their lies, crimes and misdemeanors.  Such as letting Americans die so as not to spoil the campaign narrative.  Al Qaeda was reeling and in retreat.  And they couldn’t allow security concerns in Libya to upset that message.  So they abandoned the Americans in Benghazi.  And hoped the resurgence of al Qaeda in Libya wouldn’t hurt President Obama’s reelection chances.  And counted on their friends in the media not to question and disseminate the lie about the YouTube video causing a spontaneous protest that caused average Muslims to pull out rocket propelled grenades and mortars from their wallets and purses to wage war.  Now contrast the sycophant American press to the British press (see David Cameron says British Press plays ‘vital’ role in democracy by Matthew Holehouse posted 1/17/2014 on The Telegraph).

“At its best, the British Press, the political Press, have a vital role to play in our country.

“Yes: rowdy, tenacious, sceptical, uncontrollable, often uncomfortable for our politicians. But British political reporting is deservedly respected around the world, for the way it probes, it inquires, it scrutinises, and these things are linchpins of our democracy…”

Mr Cameron spoke movingly of a trip he made, accompanied by political reporters including from the Daily Telegraph, to a newspaper office in northern Sri Lanka, where journalists had been murdered after criticising the government.

“It was an incredibly powerful moment. It was a reminder of just how fortunate we are in this country to have a Press that is free, that is open, that is able to stand up to the powerful.”

Without an independent and free press how do you keep government honest?  How do you protect the American people from the lies, crimes and misdemeanors of government?  You can’t.  Instead you get propaganda that helps the powerful grow more powerful.  And it eventually gets to the point that politicians no longer debate in the arena of ideas.  They just look for opportunities to destroy their enemies.  Challengers to their power.  Like Chris Christie.  Who polls better against Hillary Clinton than any other potential Republican candidate.  So they attack Christies over Bridgegate.  To destroy him.  And they circle the wagons around Hillary Clinton to protect her from her incompetence and indifference over Benghazigate.  While never worrying what their helping the powerful to become more powerful could do one day.

Magnetic Field, Recording Head, Bandwidth, Wire, Magnetic Tape, Helical Scanning, VCR, and Tracking

Posted by PITHOCRATES - October 9th, 2013

Technology 101

(Originally published December 12th, 2012)

By passing a Long Thin Wire across a Fluctuating Magnetic Field we could Impart a Signal onto the Wire

A magnet has a north and south pole.  Between these poles is a magnetic field.  If a piece of metal comes into contact with this magnetic field the magnetic field will draw the piece of metal towards it.  We can make a magnet by running a current through a wire wrapped around a metal bar.  When a current flows through the wire it will create a magnetic north pole at one end of the bar.  And a south pole at the other.  With a magnetic field in between.  When we stop this current flow the magnetic field goes away.  We can see this in a junk yard when a crane-mounted electromagnet picks up a junk car.  Moves it over where they want it.  And then they stop the current flow.  When they do the magnetic field goes away and the car falls.

We can’t see a magnetic field but it is there.  And it can do work for us.  Not just moving cars.  But a lot of other things.  Such as recording an audio signal on a wire.  Like a spoken voice.  Or musical broadcast on the radio.  By passing a long, thin wire across a fluctuating magnetic field we could impart a signal onto the wire.  Leaving a magnetic footprint, if you will.  Pulling this same wire across a de-energized electromagnet the magnetic field from the magnetic footprint in the wire will reproduce the audio signal that originally imprinted it on the wire.  Once a recording head picks up this signal it is amplified and sent to a speaker, reproducing the sound in the air where we can hear it.

Thus began recording on a magnetic medium.  Which was superior to recording on wax phonograph records.  Greatly increasing the length of audio recordings.  And simplifying the editing process.  As you can stop the recording process and resume it right where you left off.  And you could cut and splice a wire.   Which you just couldn’t do with wax phonograph records.  And a wire had a pretty good sound quality for the day.  These recorders pulled a very long wire across the recording head at a pretty good speed.  Recording a lot of information.  Giving it a pretty good bandwidth.  For the day.

A Magnetic Tape is a Plastic Film with a Thin Coating of Material that can hold a Magnetic Footprint

Bandwidth.  You hear a lot about it.  Especially with the Internet.  People know they need a lot of bandwidth for live-streaming video.  Which is why they have broadband Internet access.  Like a cable modem.  But what is bandwidth?  A mixture of frequencies makes up sound.  Take a 4-piece rock band.  Lead guitar, rhythm guitar, bass guitar and drums.  The bass guitar plays low-frequency notes.  And the lead guitar plays high-frequency notes.  The frequency ‘distance’ between the lowest frequency and the highest frequency is bandwidth.  If this band put out a recording with only the bassist playing one note for 3 minutes this would need very little bandwidth.  Because there would be only one frequency.  Whereas a recording with all four musicians playing every note possible with their instruments would require a lot more bandwidth.  Because this recording will have a great many different frequencies coming together to make music.

This is why recording on wire worked so well.  There is a direct relationship between bandwidth and recording speed.  The greater the recording speed the greater the bandwidth.  Picture a lie detector machine with those needles moving back and forth across a moving strip of paper.  Consider the needles moving back and forth slowly as low frequencies.  And the needles moving back and forth quickly as high frequencies.  You can see information in the resulting patterns.  The person administering the test makes notes on the paper identifying the questions that caused the needle movements.  If that paper moved at one fourth the speed, though, instead of getting useful information you would just see scribbles on top of scribbles.  The ‘high frequencies’ would be especially lost.  Providing no useful information.  Just noise on paper.  This would be an example of insufficient bandwidth for the amount of information in the source signal.  So the paper moves at a sufficient speed to provide the necessary bandwidth.  Just like the wire recorder.  Of course, the greater the recording speed the faster the recording medium will pass across the recording heads.  Which means if the recording medium isn’t long enough it may run out before the recording is complete.  Wire worked well because it is very thin.  Allowing a very long piece of it to wrap around a spool.  But it wasn’t very user friendly.  Like a fishing line off of a fishing reel it knotted and tangled easily.  And despite having a pretty big bandwidth the sound quality was not very good.

An improvement in recording medium was magnetic tape.  Which was a plastic film with a thin coating of material that could hold a magnetic footprint from a changing magnetic field.  Produced by a magnetic recording head housed in a drum.  Which pressed the tape flat under the recording head.   Audio recorders have fixed heads.  Much like the wire recorders.  The tape mechanism carefully pulls this coated plastic film quickly over the magnetic head.  To provide the necessary bandwidth for quality audio reproduction.  While the tape speed isn’t so fast that it results in short recording times.  During the height of the audio cassette era the typical audio cassette held 90 minutes of music.  Which could hold most double LPs.  For those too young to remember, that was two long-play vinyl records we once played on phonographs.  Spinning at 33 ⅓ revolutions per minute.

The Video Cassette Recorder (VCR) is an Engineering Marvel thanks to Helical Scanning

That was audio.  It was a different story with video.  Because of bandwidth.  There was a lot more information in a video signal.  Which meant a lot more frequencies to imprint on a magnetic tape.  And a lot of high frequencies.  For both video and audio.  Requiring a fast tape speed.  But increasing the tape speed meant a longer tape.  But a tape long enough to record a movie with fixed recording heads required a lot of tape.  Requiring very large reels.  Or cassettes.  Too large to be practical.  For unlike a wire we can spool onto a reel like a fishing line (going from one side to the other as we wound the wire onto the reel and then back the other way, placing coils of wire side by side as well as on top of each other) a flat magnetic tape only wound neatly on top of itself.  Creating a conflict.  Either having the length you needed but not the speed.  Or having the speed you needed but not the length.  They needed a way to solve this conflict.  And they did that with the helical scan.

Instead of moving the tape fast they moved the recording head fast.  The tape moved at a manageable speed that provided suitable recording times.  The heads, though, instead of being fixed were housed in a rotating drum.  That spun very fast.  And at an angle to the tape.  Instead of the heads recording continuously along the tape in the same direction the tape traveled these heads recorded in diagonal swaths across the tape.  Which is why a video tape is wider than an audio tape.  To be wide enough to record a series of strips of the video signal across it.  When recording signal processing circuits break down the source signal into these short pieces and imprints them on the magnetic tape.  When playing back signal processing circuits reassemble these strips into the continuous movie they once were.

The video cassette recorder (VCR) is an engineering marvel.  Or was.  You just put a video cassette into a VCR and pressed play and it did the rest.  It pulled enough tape out of the cassette to wrap half way around the spinning drum.  A bunch of rollers and guides routed the tape over the erase head, the video head drum and the audio head.  A capstan (a precision rotating spindle) spun at a constant speed to regulate the speed of the tape over the heads.  A rubber wheel (or two) pressed the tape against the capstan.  And if the VCR didn’t reassemble these strips quite right there was something you could do to help.  Adjust the tracking.  Which helped to fine tune the reassembling of those diagonal strips from the video tape.  Once you did that you only needed one other thing.  Popcorn.  Then you could enjoy a night at the movies in your own home.  Thanks to helical scanning.  And the VCR.
