I've never had a bleep like that before. It sounds like the BBC2
test
signal.

History of computing comes to mind...

https://en.wikipedia.org/wiki/PC_speaker

If the sound system is down (driver is not working),
OSes are allowed to use "PCBeep". PCBeep is considered
to be the "backup notification system". If the sound
card goes missing, software is allowed to abuse that.

On my desktop machine, the beeper is tiny and hardly heard. I could not
find a bigger unit.

Most desktops don't even have one. This one is unusual.

Mine originally had nothing. No beeper, nor the wire connected to the
audio card (IIRC the card doesn't have the connector, either). When I
bought it online I forgot to add the internal speaker/beeper component,
I did not see it. So years later I bought a bag of 10 or 20 from Amazon
for a puny price...

On laptops, the pc beeper is usually routed via the sound card, and it
can go at top volume by default :-/

I didn't know there was still a beeper function unless you were using
DOS!

Even in Linux. It is a standard.


But it's outdated, everyone has real speakers.


Sure. But you need them to analyze some bios problems.


I use the screen.

The BIOS beeper/speaker has also been tied in the
past, to games. The motherboard speaker can be
used as a 1-bit DAC, and game soundtracks can be
played through it. (A certain era of Macintosh gaming
did this too, and there were probably 200 games
that did the 1-bit DAC thing... The fidelity is
surprisingly good. 1-bit DACs have also been
used in expensive stereo equipment, in case
you thought that nobody would dare try that :-)
To make that work, just crank up the clock rate,
and the 1 bit DAC does a damn good job. The DAC
needs to be followed by a reconstruction filter,
which is what makes it work.)

https://en.wikipedia.org/wiki/La_Abad%C3%ADa_del_Crimen

«The music played in the game corresponds to the Minuet in G major and
the sonata for flute BWV 1033 from Bach, and Crystal Palace from
Gwendal. The original PC version also featured the "Ave Maria" from
Schubert, in a short chorus recording that played through the speaker
when the player went to the church.

There is a form of copy protection on the PC version: if an illegal
copy
of the game was created, in the church area, instead of "Ave Maria", a
voice crying "Pirate! Pirate! Pirate!" several times will be heard
instead, and after that the game will crash.»

Copyright sux.

Oh, yes, but in this case it was funny.

There was at the time a "copyright" program that would copy most
original 5¼ floppies. This game worked just fine, IIRC.


My first recollection of being naughty was using a stereo with two tape
decks to duplicate ZX Spectrum games at double speed. All that trouble
they went to with unusual baud rates to stop programs copying the tapes,
I just used a simple stereo.


:-)

I heard it did not always work.


It did if you used decent tapes and a decent stereo. It needs to be good at copying high frequencies. Every single copy I made (450 games) worked perfectly. Of course if you copied a copy of a copy things didn't always work out.

Not to nag, but you might also consider not allowing PDFs
to load in your browser. They're a common attack method.
They're not webpages. They only load at all because Adobe
has been trying, for many years, to find a way to hijack
the Internet. (Flash, PDF, AIR.)

adobe isn't trying to hijack anything, certainly not with pdf,
which isn't even owned by them.

This is inexact.

it is not.

There is a published PDF standard, which they no longer own.

i said that.

But they
can add, and do add, additional features that only them support
properly (because they don't publish).

as can others, however, content creators are not required to use
them, and it would be foolish to do so. it's rare that a pdf on a
web site is anything fancy.


On the contrary. Most government forms and complex forms I have
seen use them.


I've seen the same.


They only need to be using adobe software for the creation, and bingo!
It happens even if they don't intend to. They may not even be aware that
only adobe reader displays those PDF correctly, and sadly, adobe no
longer provides their reader for all operating systems.


the point is that a user can click on a pdf and read it directly
in the browser just as they do with any other web page. it's just
another link. if the pdf is interesting enough to keep, click
another button to save it, otherwise, close the window (or click
the back button) and it's gone.


which just copies the file from temporary directory to final
directory.


Depending on the size of the pdf and browser internal programming, it
might not. If it's small enough, the browser might be storing and
rendering it entirely in memory. And only making an actual physical
copy if you ask it to do so, either by saving as a file someplace, or
a print job (and that depends on print manager settings too) which
will be deleted once the printer no longer needs it, or later on
during maintenance/cleanup. it's treated as a temporary file. And
that depends on your print manager settings/printer que setup, etc.
You might opt to send directly to printer right away, don't
que/spool. No temporary files will be created unless the print job is
too big to send at one time. And, again that depends on your setup.
It may que them in memory and not use temp files at all.


Ah, well. Maybe.

Firefox has some support to display PDF internally without using a
plugin from adobe or elseware. But the rendering is not as perfect. I
don't know about other browsers, but I suspect they do similarly. I
believe PDFs are safe as long as the reader does not supports or ignore
the possible javascript code they can contain.

You'd be hard pressed to develop anything worse than Adobe's Acrobat
Reader.* Just try printing something from it, you won't get anything
remotely like what's on the screen.* I often have to screengrab it and
print it from Paintshop Pro.


Huh? I never had any such problem printing from adobe reader reliably.


I have, I never get the size I expect.* Easier to put it into a photo
editor with a screengrab, then you can fit to page etc.


Oh. I can't say I had that problem.
I had problems with printing several pages per sheet, though, not the
ordering I expected.


** Usually if a PDF is linked it's because you want a copy.
So it makes sense to set your browser so that you
download PDFs. Then you don't have to keep going
back to the website every time you want to look at it.
A PDF is not necessarily safer on your computer than in
the browser, but there are two differences:

And because the leaflet can be printed, with accuracy.

Adobe, accuracy, ROTFPMSL!


Well, adobe or others :-)


Anything should be able to print properly.* PDF doesn't help here.


There are printers now that talk PDF, instead of postscript.

Pdfs are vector formats and by definition can be scaled to any size without
losing resolution*. A pdf print dialogue box always has a "shrink to fit"
and/or "scale to page" option.

By taking a screenshot your rasterising the page and losing the benefit of
the pdf.

* Unless it had been saved as raster format. But that's dumb so not common
these days.


Wait, there are many scanners or scanner applications that save directly
as PDF. And in that case, they use bitmaps.


Anything should be able to print properly. PDF doesn't help here.


Actually it does. That's the whole point of the format. It is completely
device agnostic so it doesn't matter what you're viewing it on or printing
it with it should print as the author designed it. You often see forms as
word files and they never print or render properly.


Right.

Not mine, a £40 Epson. It can't even handle ink properly. If it runs out mid page it just stops. Then after I replace the ink it ejects that sheet and prints the other half on another page?! what am I supposed to do, sellotape them together?

The beep error codes, include a RAM error beep code.

This allows telling you the system RAM is bad, without
requiring anything other than that motherboard piezo.

The beep pattern is "coded", so more than one error
indication can be delivered to the user.

Possibly one of those adds you get triggered the blast (maybe

and
scared me ****less. I must say that you guys on Windows get
more fun
that us poor lads on Linux :-P

I've never had a bleep like that before.Â* It sounds like the BBC2
test
signal.

History of computing comes to mind...

https://en.wikipedia.org/wiki/PC_speaker

If the sound system is down (driver is not working),
OSes are allowed to use "PCBeep". PCBeep is considered
to be the "backup notification system". If the sound
card goes missing, software is allowed to abuse that.

On my desktop machine, the beeper is tiny and hardly heard. I
could not
find a bigger unit.

Most desktops don't even have one.Â* This one is unusual.

Mine originally had nothing. No beeper, nor the wire connected to the
audio card (IIRC the card doesn't have the connector, either). When I
bought it online I forgot to add the internal speaker/beeper
component,
I did not see it.Â* So years later I bought a bag of 10 or 20 from
Amazon
for a puny price...

On laptops, the pc beeper is usually routed via the sound card,
and it
can go at top volume by default :-/

I didn't know there was still a beeper function unless you were
using
DOS!

Even in Linux. It is a standard.

But it's outdated, everyone has real speakers.

Sure. But you need them to analyze some bios problems.

I use the screen.


When it fails to display, the error is before video testing :-)


Which means the video card's ****ed.


Not necessarily.

The BIOS follows a sequence of tests. There are many things that can
fail before it even tries to write to the video. The failures are
reported with sequences of short and long beeps.

https://en.wikipedia.org/wiki/Power-on_self-test


The BIOS beeper/speaker has also been tied in the
past, to games. The motherboard speaker can be
used as a 1-bit DAC, and game soundtracks can be
played through it. (A certain era of Macintosh gaming
did this too, and there were probably 200 games
that did the 1-bit DAC thing... The fidelity is
surprisingly good. 1-bit DACs have also been
used in expensive stereo equipment, in case
you thought that nobody would dare try that :-)
To make that work, just crank up the clock rate,
and the 1 bit DAC does a damn good job. The DAC
needs to be followed by a reconstruction filter,
which is what makes it work.)

https://en.wikipedia.org/wiki/La_Abad%C3%ADa_del_Crimen

«The music played in the game corresponds to the Minuet in G major
and
the sonata for flute BWV 1033 from Bach, and Crystal Palace from
Gwendal. The original PC version also featured the "Ave Maria" from
Schubert, in a short chorus recording that played through the
speaker
when the player went to the church.

There is a form of copy protection on the PC version: if an illegal
copy
of the game was created, in the church area, instead of "Ave
Maria", a
voice crying "Pirate! Pirate! Pirate!" several times will be heard
instead, and after that the game will crash.»

Copyright sux.

Oh, yes, but in this case it was funny.

There was at the time a "copyright" program that would copy most
original 5¼ floppies. This game worked just fine, IIRC.

My first recollection of being naughty was using a stereo with two
tape
decks to duplicate ZX Spectrum games at double speed.Â* All that
trouble
they went to with unusual baud rates to stop programs copying the
tapes,
I just used a simple stereo.

:-)

I heard it did not always work.

It did if you used decent tapes and a decent stereo.Â* It needs to be
good at copying high frequencies.Â* Every single copy I made (450 games)
worked perfectly.Â* Of course if you copied a copy of a copy things
didn't always work out.


Oh, I only had access to a shared Spectrum a few hours per week, so I
couldn't experiment much.


It was my first computer.


Mine was the Amstrad PC 1512DD

I've seen the same.

false.


At which point I disregard what you say :-P
