January 14, 2002

Started a 2002 What's New. Archived the 2001 What's New.

January 13, 2002

Added the latest and best of our JavaScript "N" calculators to our
Magic Sinewave library page. CD ROMs containing thoudands of
useful sequences, plots, and generation sourcecode can now be made
available to Magic Sinewave partners and associates.

January11, 2002

Here's an interesting Product Liability Notice.

January 8, 2002

Proved the feasability of partial differential Magic Sinewave
calculators. These are ~much~ faster. More significantly, their
key calculation time only goes up as the square of the number of
pulses rather than the cube, meaning that as many as several
thousand harmonics can now be forced close to zero.

Preliminary calculators and autogeneration code is currently available
to our Magic Sinewave partners and associates.

January 4, 2002

Found an interesting web sit of electronic logos useful to help
identify strange chips. Still could use your help on identifying
this chip. These fiber optic transceivers look super interesting.

January 3, 2002

You can easily build your own gas chromatograph or similar lab
instruments with these TSD temperature sensitive detectors
that double as precision mass flowmeters. Listed with our other
current eBay offerings. Two remain available.

January 1, 2002

Verified an important marketing lesson: Our surplus recorder pen
motors refused to sell at any price, but we quickly sold out of our
laser light show galvo kits.

December 22, 2001

Uploaded MSCAL172Q.SHTML,, a Magic Sinewave that zeros out
its first 172 even and odd harmonics. Code (while still suboptimal)
is much faster, especially for Delta Friendly options. The "floating
point display shift" hassle is also now gone with a new formatter.

The amazing thing is that my PostScript program writer sourcecode
that generates the JavaScript calculator .SHTML routines builds the entire
highly custom 700K file error free in a mere three seconds!

Sourcecode is available to Magic Sinewave Partners & Associates.

December 20, 2001

Linked Arcata Pet's Imageviewer32 in the Auction Help library.
This is my favorite image processing package. It does Photoshop
essentials far faster, simpler, and cheaper. Free full featured trial.

December 19, 2001

Added a Parabola From Three Points math routine to the Cubic
Spline, PostScript, and Math library pages.

December 17, 2001

Bee just picked up a bunch of professional medical books and is
offering these on eBay. Let her know your needs.

December 14, 2001

Added a link to the US Post Office auctions to our Auction Help page.

This is basically urban lore, though. To participate, you have to own an
eighteen wheeler and live in Atlanta. Sales would appear to be quite
competetive and almost certainly favor long term insiders.

I cannot believe that all of the USPO mistakes and leftovers nationwide
can be offered in a single short auction every few months. Nor that
they would be reshipped zillions of miles.

December 10, 2001

There would appear to be all sorts of new uses for Magic Sinewaves
that have their first one or two thousand harmonics zeroed out. These
would still be more efficient than PWM, have no possibilities of audio
whine, would allow extreme speed ranges, and might permit harmonic
trapping rather than low pass filtering.

The current versions of the JavaScript calculators take too long to use
above 200 zeroed harmonics. New methods involving partial differential
evaluation are under active development. They should be much faster.

These await your funding.

December 7, 2001

Updated the mil surplus info on our Auction Help page.

Basically, all DRMO auctions are now privitized, except for
term sales and hazmat. Most are handled by one firm going by
the three names of Levy-Latham, Surplus Bid, or Government

December 4, 2001

Added some JavaScript Calculator User Guidelines and a
Chebycheff Tutorial to our Magic Sinewaves Library.

November 28, 2001

Upgraded and improved the Magic Sinewave Development Proposal.

November 25, 2001

Continuing to experiment with the high level nav on our home page.

November 23, 2001

Found a unique cache of early General Radio gear in what appears
to be restorable condition. 616, 1106A-C, 696C, 617C, 699A, 616D
617C, 619E, 619P1, 614C, 612C, 693B, 692B, 1107A, bunches more.

email me if you have any interest in these.

November 22, 2001

Stripped out the Gould recorders for parts. The pen servos should
make dandy laser light show galvos. Now up on eBay.

It really saddens me to strip out equipment that refuses to sell for
fractions of a cent on the dollar. But, then again, line cords at an auction
are ~much~ cheaper when they are attached to 386 computers.

November 21, 2001

Just awarded a ton (literally) of professional law books. email me
if you have any interest in these.

November 23, 2001

Revised and updated our Steplocked Magic Sinewaves tutorial in our
Magic Sinweaves library.

November 21, 2001

Added some color coding and emphasis to the main nav blocks on our
home page.

November 20, 2001

Here's some tips on using the new Magic Sinewave "Q" calculators:

(A) The highest amplitude values may sometimes "mode jump"
on you, giving bizarre results. Valid sequences will always have
pulses that start before they end, do not overlap, and do not exceed
90 degrees. The workaround is to "sneak up" on any problem values,
starting with a valid lower amplitude and incrementally increasing it.

(B) If a solution is slow converging, try asking for a somewhat higher
or lower amplitude to help it along.

(C) Extremely rarely, a solution may "oscillate" between two amplitude
values. The workaround is to temporarily ask for a very slightly higher
or lower amplitude. Later, you return to your desired target amplitude.

(D) Calculation time goes up as the fourth power of the number of
pulses, so slow high pulse calcs are normal and expected. Optimizing
one decimal point at a time is much faster than going for all eight
at once.

(E) The most common causes of JavaScript errors are using a browser
other than Internet Exploder or failing to wait before a load is complete
before activating any box or button.

November 19, 2001

to our Magic Sinewave Library. Along with their sourcecode.

Even as the number of MS transitions approaches PWM, there apparently
would ~still~ be advantages of single versus double switch flips for higher
efficiency, lack of any need for modulation or demodulation, easy three
phase compatibility, and a "carrier" amplitude that never significantly
exceeds the fundamental. While offering very wide speed ranges that
are combined with no harmonics in the audio range.

November 17, 2001

Ever see that "Convert your television into a big screen oscilloscope"
scam ad that has gone on for decades and decades? I just got a whole
pile of Tektronix 7912AD's that actually do this! Yeah, they are huge
and ungainley, but they still hold their own as high speed digitizers. As
well as being able to convert scope probe inputs into video outputs.

email me if you want to play with some of these.

November 15, 2001

Just got some Quantachrome instruments used for particle surface area
analysis. Apparently for everything from toner to geological clay to
respirator filters. You can
email me for details.

Price is pennies on the dollar on current ion units. Older models
also available. As are sample holders and other accessories.

November 13, 2001

Added a new brief intro apnote to the Magic Sinewave page.

November 11, 2001

Examples of PostScript routines that automatically write their
own JavaScript programs (!) include newly posted MSCAL108Q.PSL

November 10, 2001

You say you don't want a hundred harmonics? MSCAL108Q.SHTML
won't give them to you. Even longer sequences are newly available
per our InfoPack service.

The Magic Sinewave calculation times and complexities do go up as
the fourth power of the pulses in use, so these longer sequences will
be slower. Practice on the shorter ones first.

November 9, 2001

Did you hear about the deli operator who was having trouble collecting
his bill from the avairy? He took a tern for the wurst.

November 8, 2001

The latest Magic Sinewave calculator is our MSCAL76Q.SHTML.
It is a simple digital sinewave synthesizer that zeros out the first
SEVENTY SIX harmonics! A delta friendly option gives you full
three phase compatibility and still zeros out all of the even and odd
harmonics 2 through 58. BEFORE FILTERING!

Longer Magic Sinewave sequences like these still offer significant
efficiency advantages over conventional PWM; they also minimize
audio whine problems and allow very wide motor speed ranges.

Consulting services available per our InfoPack services.

November 6, 2001

The new Magic Sinewave "Q" calculators are intended for Internet
Exploder rather than Netscape. If you experience Netscape blowup
problems, rerun the source code using a true /Netscapeok variable

This will defeat the conflicting neat-o IE automatic carrier tracking.

Much as I like Netscape, we are down to less than one in six users,
and the double testing and frustratingly infuriating differences no longer
seem worth the hassle.

November 3, 2001

Just completted debugging a PostScript system that writes Javascript
Programs! Its big advantages include the ease with which PostScript can
read or write any disk file in any format. Magic Sinewave calculators
for larger sizes take twelve to eighteen hours done by hand; the PostScript
routines reduce this to mere minutes.

See MSCAL44Q for the first sample, which includes a premium grade delta
friendly solution that has zero harmonics up to the 34th!

Custom assistance available per our InfoPack services.
More to follow as time and banner advertisers permit.

October 30, 2001

Got a pair of HP 3455A super dooper digital voltmeter / data acquisition
systems. 7-1/2 digits with calcs. email me if you have any interest in these.

October 27, 2001

Added new links to our Auction Help Library pages.
Split the classic tutorials from the new files on both the Home
and the Library Access page.

October 25, 2001

Picked up four GOES satellite time clocks. email me if you have
any interest in these.

October 24, 2001

Added a new Magic Sinewave data accuracy analyzer as
MSCAL28Q. This lets you easily evaluate how many bits of
amplitude data are needed for a given minimum distortion.

It turns out that 8-bit amplitude data can sometimes be used
with limited distortion reduction (half percent unfiltered) , but 12-bit
or 16-bit amplitude lookup tables are strongly recommended.

October 20, 2001

It turns out that delta friendly Magic Sinewaves only need half as
much data storage as regular ones. Added a file reduction note and
new algorithms to DELTAPAT.PSL

October 19, 2001

May be getting a bunch of Tektronix 7912AD's. These are a 750 MHz
9 bit digitizer somewhat long in tooth. Please email me IMMEDIATELY
if you have any interest in these.

Otherwise, they will be scrapped out for parts. They do still list for $8600
each at major dealers.

October 18, 2001

Added an improved Delta 322R to our Magic Sinewave Library.
This is probably the "best" magic sinewave so far for three phase
motor uses. The DELTAPAT.PDF demo has also been updated.

October 15, 2001

Just picked up a pair of Olmpus microscopes. Also some 60 Hertz
military servo motors. email me if you have any interest.

October 13, 2001

Uploaded a new DELTAPAT.PSL utility and DELTAPAT.PDF demo
on three phase formatting to our Magic Sinewaves Library.

October 7, 2001

Added a brand new Precision Fonts and Bitmap Manipulation library
page. Lots of demos and utilities to do true integral antialiased fonts,
image relettering, direct PDF bitmap conversion, and even combining
aerial photography with topographic map info.

October 4, 2001

Put a precision pulse metering pump, a time mark generator, and a poly
storage tank up on eBay for auction.

October 2, 2001

Just got a bunch of fancy digital scales. You can email me for details.

September 30, 2001

Did I ever show you this aerial photo of Pacman, Arizona?

September 27, 2001

Check out the stunningly exceptional apparent resolution in the lower
right corner of once again updated PDF2BMP.BMP and its companion
PDF2BMP.PSL sourcecode. This is SEVEN POINT type on a screen!

The secret is a pile of insider stunts that include true grayscale antialiasing,
reduced visual spectrum, reduced contrast, kerning, true alpha transparency,
and a mere one click of sharpening.

September 26, 2001

A sneaky trick called integral grayscale antialiasing can dramatically
improve the viewability of low resolution screen fonts, image retouchings,
and ebooks. These techniques can provide up to THIRTY TWO times
the information per pixel as ordinary fonts. And they work on CRT's.

I've just added a new ANTIGRAY.PSL true gray antialiased font character
extractor. A companion
PDF2BMP.PSL character positioner along with its
PDF2BMP.BMP demo has also been recently upgraded.

You can also see MUSE141.PDF for an older antialiasing tutorial. Or
ANTIGRAY.PDF for a typical antialiasing font work screen.

September 23, 2001

Just got a pair of classic TASCAM TSP-8 classic half inch rack mount
reel-to-reel audio recorders with remotes. email me for details if you want
one or both of these. We also have lots of half inch tape available.

September 20, 2001

Once you start writing PostScript code, there's no telling where it
will end up. Sometimes you can nudge it in a certain direction, but
other times its got a mind of its own.

Added transparent overlay and FULL ALPHA TRANSPARENCY (!)
capabilities to
PDF2BMP.PSL and its PDF2BMP.BMP demo.

September 18, 2001

Well, I did just cheat a bit by adding four clicks of sharpening to that
PDF2BMP.BMP by using ImageViewer32. Note the exceptionally
legible four point type.

September 17, 2001

Added CIRCULAR ARC capabilities plus improved error trapping
PDF2BMP.PSL and its PDF2BMP.BMP demo. Virtually any math
function can now be directlly plotted and pasted into any .BMP image!

Consulting services available per http://www.tinaja.com/info01.shtml

September 17, 2001

Added over a dozen fonts, individual character kerning, and line
drawing and area fill to
demo. Compare this against any other method of doing very small
ultra legible lettering on a .BMP bitmap.

September 15, 2001

Added a major new PDF2BMP.PSL PostScript utility that lets
Acrobat DIRECTLY(!) generate bitmap .BMP files under precise
program control

And a PDF2BMP.BMP companion demo.

I find this particularly handy for retouching ultra small and precisely
controlled lettering on my eBay test equipment panel images. Just
type, distill, load into Paint, cut and paste.

Other uses include watermarking, steganography, and letting you
alpha blend two .BMP files, perhaps a map and aerial photography.

September 7, 2001

Just got several zillion O-rings off the feds. Mostly 5/8 od by 3/32
thick and only slightly off date code. Most individually sealed in
original packages. email me if you have any interest.

September 6, 2001

A reminder about our ongoing eBay auctions.

September 5, 2001

Continuing to add new items to our Bargain Pages.

September 4, 2001

Improved our onsite search engine. There should now be fewer
but much more relevant hits. Try it above.

September 3, 2001

The latest Blatant Opportunist #65 is on My eBay Secrets.

September 1, 2001

Just got a pair of Tektronix 321A Oscilloscopes in. These are both a
nice collectible and a useful lightweight portable scope. email me if
you have any interest in these.

August 30, 2001

Started adding sourcecode to certain Blatant Opportunist columns.

August 29, 2001

Added a new Steganography ("hide in plain sight") and watermarking
book list to our Book Access pages.

August 26, 2001

Added a new Bargain Gallery Tour. Thery'll be some construction
dust for the next few days or so. Also, this might create problems
on certain NetScape browsers. Am working on a possible fix. For
now, if you have NetScape, click on the text and then on the image.

Note: The tours need a free Acrobat Reader plugin for your browser.

August 25, 2001

Our latest Guru Gonzo PostScript Utility is a mind-blower.
GALLEY1.PSL gives you full sourcecode to emulate an HTML
"gallery" or "tour" or "thumbnails page as a single downloading
compact file working from very convenient data base style entries.

You can view a Galley Slave Demo here.

August 24, 2001

Did I ever tell you about the time I worked on the old MacDonald
farm interface? It eventually reached Electronic Industries Evaluationary
status and thus became an EIE I/O.

August 23, 2001

Just got in some really nice, premium grade Barcode Scanners with a
two foot range and wedge interface. You can email me for details.

August 21, 2001

Updated and added to our Its a Gas hydrogen energy page.

August 20, 2001

Would any of you be interested in attending a "just for" weekend
conference and retreat? I have an in with the Black Range Lodge in
Kingston NM ( in the secret part of New Mexico you can't get to ),
so the on-site costs would be fairly low.

email me if you have any interest.

August 19, 2001

Uploaded the PCMCIA & PC Card bargain page.

August 18, 2001

The latest Blatant Opportunist #64 is on Degubbing Secrets.

August 17, 2001

Uploaded the NDT Testing bargain page.

August 16, 2001

I am not at all sure what the present status of Midnight Engineering is.

But there are these three alternative resources: (1) My own Blatant
columns contine as ezines. (2) Don Johnson offers his fine
Imagineering site; and (3) The new Entrepreneurial Engineers website
from Jack Krupansky.

August 12, 2001

Latest Tech Musings is our MUSE153.PDF on my bouncy brick
secrets, privatized military surplus, bogus water powered cars,
reducing table lookup sizes, and bounty hunting patents for $$$.

August 11, 2001

Just got a bunch of really nice new PC Card (PCMCIA) to IEEE
1284C drivers with CEN36 connectors
. These should be perfect
as Laptop-to-Anything custom interfaces. Only tiny detail is no
docs or drivers. Very easy to modify and CPLD just may be
reprogrammable, though.

I'll be happy to send you a free one if you have the capabilities to
come up with a suitable driver. Either way, email me for details.

August 9, 2001

Added some new content to our Auction Help library page.

August 5, 2001

The "autobrowser" on our Bargain Pages is now working, and we
should have most of the bricks populated soon. Our hope is to add
a a day for the next few months. Just click on the Browse
button on any page to continue your tour.

August 3, 2001

Poptronix really underdid themselves on the pyramind story.
See how many "not even wrong" technical "facts" you can spot.
Last time I checked, limestone was sedimentary, not igneous. And
20 to 20K are audio, not radio frequencies. There's no saturation
involved with the skin effect. And "ac" electrolysis gets rectified.
Plus many dozens of other howlers.

August 2, 2001

Not sure how many DRMO RCP sales remain. The (seemingly
broken) search listed another eight upcoming. But the present
ones have been extended. Cutoff date is probably October.

July 30, 2001

Expanded and improved the Offsite Links on our Home Page.

July 29, 2001

Just got a bunch of super premium Nicolet Recording Oscilloscopes.
Some 4094's and some 204A's. email me for further details.

July 28, 2001

Added an apnote on reducing Magic Sinewave table sizes. More
details will soon be posted as part of MUSE153.PDF.

July 27, 2001

It appears that the steplocked Magic Sinewave table sizes
can be significantly reduced by using quadratic interpolation.
The full data apparently needs only be stored for every eighth
amplitude, along with linear and quadratic step values.

Custom Analysis is available and depends upon application.

July 26, 2001

Got the Grand Tour Browser working on our Bargain Pages.
Should be adding lots of goodies real soon. now. Just keep
hitting the Browse bouncy brick for your tour.

July 24, 2001

The second phase of DRMO privitization has been completed,
which means that most direct military surplus sales will end about
October. Levy-Latham has merged with Government Liquidation
to become your expanded source for most mil surplus items.

July 22, 2001

Latest Blatant Opportunist #63 is our WAYWERE.PDF An
unauthorized autobiography and perspective on early personal
computing history.

May 31, 2001

Added the latest Steplock-06, Steplock-10, and Steplock-14
bridging Magic Sinewaves.

May 30, 2001

Did I ever tell you about the time I was on a New Mexico group
hike and we got caught in an unexpected storm? We found some
boards and an extremely horizontal tree and managed to build an
A frame structure, plugging up the cracks with what little raingear
we had among us.

And managed to stay quite dry in our poncho villa.

May 28, 2001

Added the latest Steplock-18 bridging Magic Sinewave. This
JavaScript calculator includes a newer, more general, and much
shorter minimum seeking optimizer code.

May 25, 2001

Over a dozen new website pages are now updated, including
TINAJA01, and the WHTNU01 gang.

Please email me with any and all link or layout problems you may
find. A tutorial on the bouncy bricks should arrive shortly. As
should the rest of the book listings.

May 20, 2001

I'm in the process of updating and improving our Main Library
. You can view the ongoing progress here.

May 19, 2001

Still have three superbly rugged silver alloy 10 conductor high voltage,
high current slip rings available. Email me if you are interested.

May 18, 2001

Further enhanced and improved our new Sample Files include.
Also rearranged our Home Page somewhat. This one works best
with IE.

May 17, 2001

We've just gone live with our new home page. You may have to use
your reload button to view it. Please report any problems .

The old home page should stay here for a while.

Sadly, several features are IE specific and not NetScape available .
The bouncy bricks are apparently not possible in Netscape 4, and
since there are only two known users of Netscape 6 (Both in a group
home for the terminally clueless), the additional time and code length
did not appear excessively urgent.

May 16, 2001

Just got a bunch of Type T Thermocouple EXTENSION wire,
Conax brand. Email me if you want to get in ahead of the hoarders.

May 15, 2001

Please email me with your seven most favorite web pages. I
may want to add a select few to our new home page.

May 14, 2001

The home pages should be next on the upgrade list. You can
monitor our progress at http://www.tinaja.com/default.shtml

One new feature will be this samper of our very best files.

May 12, 2001

Upgraded and improved our Hydrogen Energy library website.
Links to the NASA safety sites have also been newly corrected.

May 9, 2001

Got some real nice mint Marsh compound pressure gauges in.
Vacuum to 0 to 200 PSI perfect for fire engines and other drafting
pumps. 105 available. You can email me for details.

May 6, 2001

There's a big flap over on the eBay newsgroup over whether a
private business by law has to accept cash or money orders. The
answer is that they emphatically DO NOT. Especially for a contract
agreement to exchange goods and services of value.

Just got a bunch of classic Motorola 6800 microprocessor trainers.
Their answer to the KIM-1. email me if you have any interest in
picking up one or more of these community college surplus items.

Latest Tech Musings is our MUSE150.PDF on RFID, hydrogen
energy scams, PostScript trig functions, industrial waxes, and a
controversial new AAPSK coding scheme that may or may not
end up being totally what it seems.

April 29, 2001

Uh, AAPSK may in fact be bogus, and EDN Magazine just may have
gotten itself severely done in. Here's The Other Side of the Story.

April 28, 2001

Watch those reserved words! Just got into all sorts of unbelievable
PostScript problems because of a typo that mis-defined an /edn
magazine website link as /end !

April 27, 2001

Just got four super premium Nicolet Oscilloscopes in stock as
Kirtland AFB military surplus. Please email me for further details.

April 25, 2001

Added four ACOSASIN.PS PostScript utilities to pick up acos
and asin trig angle capabilities to the PostScript library page. These
have been conspicuously absent from the core PostScript code.

PostScript consulting available per our InfoPack service.

If you are into appliance repair, you already know that FSP is ~the~
superb quality factory replacement parts for Whirlpool and Sears
Kenmore. Just got a bunch of mint FSP 4326758 valve tops RA.
Not sure what they are (half of a 0.5 PSI adjustable regulator?),
but they are available super cheap if you email me.

April 23, 2001

A reminder about our InfoPack service. The latest project I just
finished involved decrypting the amazingly sophisticated Radio
Shack Wireless Humidity and Temperature Code.

These should hack beautifully as Isopod remote power monitors
for home energy efficiency. email me for further details.

Added an all new JavaScript book access page.

Jiffy Bags and a bunch of Life Raft (and sport inflatables) repair
kits. You can email me for details.

April 16, 2001

Added more files to the new Tech Musings library page. The entire
page should be done "real soon now". The web updates are talking a
lot longer than I expected them to.

that should go up in a few days can still be found here.

brand new autobrowsing and bouncy bricks Book Access
pages. The old book pages can still be found here.

March 26, 2001

Updated and improved the Bezier & Cubic Splines library page.

March 24, 2001

Got the first of our "bouncy bricks" working to go along
with our "bouncy buttons". This is a unique way to provide
groups of menu options without lots of images or long code.

Sadly, the code is IE only so far. While Netscape 6 can do
something similar, we apparently have negligible N6 users.

You can repeatedly click on your Reload button for a demo. It will
take a few weeks to fully upgrade the entire site.

new "bouncy buttons", and the greatly improved search in particular.

Some temporary redirects have been added to mix and match old and new
web pages. Should your back arrow "get stuck" on any of these, try a fast
double or triple click.

Plese report any apparent errors or problems to don@tinaja.com.

March 1, 2001

There's supposed to be a Slashdot interview in the works. More on this as
it unfolds.

February 27, 2001

One possible cure for an intermittent muffled yowling in a laser printer is to
open the top and let the cat out.

Feburary 25, 2001

Just installed a brand new upgrade of WebTrends for our site stats.
Stats will look somewhat "empty" for the next few days till everybody
gets online at the new site. Before changeover, we were running around
1200 visitors per day and 430,000 hits per month.

You can click here for Trailing Monthly stats and here for Daily stats.

Added several more in our series of Magic Sinewave Calculators.

February 20, 2001

As you probably know by now, Google has bought key assets from Deja News.
This seems to temporarily place the Guru's Lair Forum in limbo. We are working
on a solution, but our new site move and upgrade has to take precedence.

On the other hand, Google now indexes PDF files as well as HTML! .

February 17, 2001

Just picked up a Victoreen Nero 6000A X-Ray machine tester and radiation
radiation evaluator. Please email me if you have any interest in this stystem.

January 2, 2001

Hopefully, we will soon be going to a new and far more modern server that gives
us lots of opportunities to correct previous problems and add new features. In
the works are improved search and stats, dynamic html, greatly expanded tech
coverage, .shtml files that dramatically improve site management, includes, banner
rotations, secure site sales, and great heaping bunches more. Stay tuned.

Dec 28, 2000

Improved & expanded the JavaScript Magic Sinewave Calculator.
This one looks best with NetScape's continuous updates rather than
Internet Exploder's "update only after function complete" style.

Dec 19, 2000

Here's a link to an "adequate supply" of Pittsburgh Streetcar Photos

WARNING: Attempting to view all of these in one session will result
in yunz guys pronouncing "beer" as "airn". Or making a mill outta a
