Question: How do I create a mock X11 instance for testing I/O of another program?

It's not exactly easy to Google

Bob

@ΛεγίωνΜάμμαλϠΨΠʹ Xvfb?

@ΛεγίωνΜάμμαλϠΨΠʹ ?

"How do I create a ..." => "Xvfb?"

ΛεγίωνΜάμμαλϠΨΠʹ

@Bob s/How do I create a.*X.*/Xvfb?/g?

Bob

@ΛεγίωνΜάμμαλϠΨΠʹ Presumably by installing Xvfb and reading the rather straightforward documentation. After you confirm that it does what you need.

ΛεγίωνΜάμμαλϠΨΠʹ

01:01

thx, trying to figure out how vim's I/O works

Bob

Here, I'll even paste the relevant snippet:

> DESCRIPTION

Xvfb is an X server that can run on machines with no display hardware and no physical input devices. It emulates a dumb framebuffer using virtual memory.

The primary use of this server was intended to be server testing. The fb code for any depth can be exercised with this server without the need for real hardware that supports the desired depths. The X community has found many other novel uses for Xvfb, including testing clients against unusual depths and screen configurations, doing batch processing with Xvfb as a background rendering engine, load testing, as an aid to port…

If you specifically want to intercept/log X commands, there's probably some verbose logging mode. And you'd probably want an interactive X server, not Xvfb.

ΛεγίωνΜάμμαλϠΨΠʹ

@Bob mostly just to simulate keyboard input

Bob

Eh, probably something like xdotool then.

I don't exactly have a ready-made solution for you - Linux GUIs aren't really my thing. And your request wasn't particularly specific. But these should at least give you a starting point for your searches.

@ΛεγίωνΜάμμαλϠΨΠʹ something like expect?

ΛεγίωνΜάμμαλϠΨΠʹ

@JourneymanGeek small project of mine, looking for a programmatic method (not scripting) to send keystrokes to an external program

Bob

WELL THEN.

Journeyman Geek

01:41

@ΛεγίωνΜάμμαλϠΨΠʹ hm. At this point I'd suggest refining your question. Feels like something for software recommendations.se

ΛεγίωνΜάμμαλϠΨΠʹ

@JourneymanGeek Yeah, the problem is the lack of C libs for anything...

Journeyman Geek

I believe libraries are on topic there... :P

Bob

02:17

Oh I give up. No docs. No search results o.O

Oooh.

Gigabyte laptop with a GTX 1070 in it.

Ubuntu 14.04/16.04 vs. Ubuntu Bash On Windows 10 Anniversary Performance

MS POSIX subsystem => SFU => SUA => WSL...

Gone full circle? :P

arda

bash on windows is slowest prob

Bob

@arda Congrats on making assumptions without reading.

It falls behind on FS access, but is competitive with (and occasionally wins!) in memory/CPU-intensive tasks.

arda

03:46

seems like it varies

I heard many people complain about it and I think that it is a bit slow, hence I made that assumption

Bob

Which makes sense with the additional emulation required on the FS, while CPU-bound tasks would only be affected by the CPU scheduler and is otherwise basically bare-metal.

arda

my only issue is with upload atm

I can't test upload speeds on speedtest-cli or use stuff like ping

Bob

I don't think they've benchmarked network access.

arda

I wonder if there is a question about these in SU or AU

Bob

Probably. I need to install the thing first.

Don't have a local copy of 1607 at work, so it's gonna have to be on Azure

Needs admin apparently

Bob

@arda That would've been my first guess :P "Permission denied"

Bah, the 1607 VM is still installing updates.

arda

@Bob mine was using sudo

that worked

Bob

@arda Does that put you in a Windows high integrity level?

arda

nope

but imo it should pop up UAC dialog

Bob

04:01

Not if the *nix system keeps a separate dir structure

arda

other stuff that needs icmp still doesnt work though

@ThatBrazilianGuy you might be missing out.

Bob

@JourneymanGeek Also dolls.

Also "escort" missions. Especially "tiger escorts". Not sure if better or worse than "cougar" ones...

Journeyman Geek

Lol.

@Bob oh. SR4 has no Russian voice.

I played it with French. Southern would likely be my pick for a replay.

@Bob you rarely get to use one as a weapon tho.

arda

sigh

you made me want to redownload sr4

Journeyman Geek

@arda SR3 is my favourite of the series

Once in a while I hear how someone hits lottery. At one period there were several hits one after another which raised suspicion in me. I do not believe people are hitting lottery as claimed. I think this is all part of a fraud agenda.

Bob

@JourneymanGeek How'd the job thing go?

Journeyman Geek

@Bob it went. No real information other than that some of the other guys are on longer contracts.

My guess is the first day on the job's the real orientation

Bob

08:19

O.o

This all sounds very dodgy :P

Don't accept any drinks! :P

Journeyman Geek

Loool

It's basically a whole load of hr people who companies outsource stuff to.

djsmiley2k

@Boris_yo ?_?

Boris_yo

@djsmiley2k You think lottery is legit or a colluded fraud?

Journeyman Geek

08:44

@Boris_yo as with any form of gamling, the odds are always in the house's favour

Boris_yo

@JourneymanGeek That I know but it angers me that they employ strategy of fake winnings to artificially stimulate their sales.

While they easily handing out winnings how many of population does it take to offest losses from winnings?

And with frequency they did that at one period, I would not believe they can do that without stimulation of sales.

That's BS dream selling served on a silver platter to people who believe in fairy tales who lost touch with reality.

i'm having a senior moment. why would a spambot fill out a web form? what is the owners reasoning for it?

@Burgi Uh... spam?

Journeyman Geek

@Burgi I think they just fill anything fillable

Burgi

@JourneymanGeek for what goal?

@Burgi in case its publically posted. its just less intellegence needed

I just discarded driver floppy for windows 2.01

1 disk for the driver for the logitech mouse

Guitar Shoe Dave

surprised that floppy still works

I found a couple floppy disks the other day while packing my stuff to move home... can't remember what they were for

But I'm pretty sure I have no floppy drives left anywhere in the building

Heck, even finding a DVD drive is hard, my old ones only have IDE and none of my boards support that anymore

Guitar Shoe Dave

Anybody remember installing win 95 from floppies?

Last Disk... CRC error.. abort retry fail

!!facepalm

ChatBot John Cavil

Guitar Shoe Dave

13:55

Burgi

what was the point in the abort/retry/fail dialog?

Guitar Shoe Dave

I never really understood the difference between abort and fail imo

Burgi

exactly

Bob

@Burgi abort => kill the process, retry => try operation such as disk read again, fail => report error to the program (status code)

Guitar Shoe Dave

whenever those issues would happen, id call a friend next and ask them if they had the same disk # and go next door and grab it real fast.

DavidPostill

13:57

@Burgi Sometimes "retry" would work if the floppy disk heads were slightly out of alignment or something.

Burgi

yeah

but in my experience abort and fail did the same thing

Guitar Shoe Dave

Sometimes dust caused it to happen as well on the disk heads

id occassionally open the closure and blow in it to fix.

Burgi

> These messages have become an example of frustrating and useless computer messages in popular culture[citation needed]

Guitar Shoe Dave

LIKE THE OLD NINTENDO CARTRIDGES

DavidPostill

Handling Diskette Errors

Diskettes can go bad. Usually they start by developing "soft" errors, which are recoverable by retrying the operation several times. Eventually the soft errors turn to "hard" errors that can not be recovered.

How do you know when a diskette is starting to go bad? Your first clue will be an error message like "Disk error reading Drive x, Abort, Retry, or Ignore?" When you start to see that happen to a diskette, it's time to do something.

Try the diskette in another diskette drive to ensure that the diskette is the problem, not the drive.

Bob

13:59

@Burgi abort returned an error code. most programs just didn't bother handling them properly and crashed anyway

Rahul2001

I never even got to see an abort, retry, fail prompt

Burgi

@Rahul2001 try installing drivers on XP and eject the cd halfway through

DavidPostill

Yeah, that should do it.

Guitar Shoe Dave

It returned an error code but wasnt visible to the user which made it confusing in a way..

Burgi

Abort, Retry, Fail?

In computing, "Abort, Retry, Fail?" is a computer error message in the DOS operating system which indicates a critical error and prompts the end-user for the course of action to follow. This and other similar error messages are given by the default critical error handler. The message was sometimes used as an example of poor usability design in computer user interfaces. == Background == The DOS family of operating systems (such as MS-DOS, PC DOS and DR-DOS) date back to early microcomputers, which were primitive by modern computing standards. A primary design consideration was that software written...

Guitar Shoe Dave

14:02

See also: PC LOAD LETTER (office space lmao)

DavidPostill

There you go. If the drive wasn't closed then use Retry

"Retry (R): DOS would attempt the operation again.[2] "Retry" made sense if the user could rectify the problem. To continue the example above, if the user simply forgot to close the drive latch, they could close it, retry, and the system would continue where it left off."

Bob

@GuitarShoeDave eh, same thing modern APIs do. they just don't prompt the user first.

Guitar Shoe Dave

@bob: true true..

Bob

the error code was specifically supposed to inform the program that something broke, not the user

the program can then inform the user if it wants to

Guitar Shoe Dave

They could have potentially corrected it and had retry fail... and always just returned the execution status

Not sure why the user had to opt in for that still.

Bob

14:05

@GuitarShoeDave because single-tasking OS

Rahul2001

Abort retry fail is going to be an Easter egg in my next programming...

Bob

if an error code caused a program to get stuck in an endless loop...

Guitar Shoe Dave

OH DUH you're right... makes sense now.

DavidPostill

@GuitarShoeDave Because see above. User intervention is required to close the drive properly.

Guitar Shoe Dave

yea yea yea

Bob

14:05

that's what the abort was for I think

Guitar Shoe Dave

Totally understand now.. forgot about that whole single user concept

jeeze heh

Bob

retry was cause the hardware was more unreliable at the time :P

though I'm not old enough to have used a drive with an actual manual latch

unless you mean forgetting to insert the disk all the way...

DavidPostill

@Bob Or the drive door was left open.

Burgi

@Bob it was more the media was unreliable

Guitar Shoe Dave

@Bob Some of us are :/

Bob

@DavidPostill come to think of it, you still get retry prompts for CD drives these days (cc @GuitarShoeDave)

DavidPostill

Some of us have use punched cards and paper tape ...

Rahul2001

That's a particular brand, right?

Burgi

yes

DavidPostill

@Rahul2001 Probably was. Now it is a generic term. Same thing happed with "Hoover" and "Biro", etc

Rahul2001

I have no idea what those are...

Burgi

14:12

biro = ballpoint pen

hoover = vacuum cleaner

@DavidPostill and sellotape

djsmiley2k
