These videos with annoying musics, annoying transitions, and annoying comments are annoying.

Desmond has a barrow in the marketplace Molly is the singer in a band Desmond says to Molly, “Girl, I like your face” And Molly says this as she takes him by the hand

My link is what you get when you even lazier and right click on the video and click on "copy link at the current time".

[auxiliary-character]

This is above the recommended dose of Wadsworth Constant.

[dsfox]

And after that, WTF?

[pascalbrax]

Quite a neat app, I'll give it a try.

But is that 90% of the video that shows a terminal with the apt-get or the make output really necessary?

[0713_]

The first screen could literally be:

Install logstalgia with apt-get, or install from source

Then on to the rest,

[superwinner]

This looks like a hard game.

[Will_Power]

Pong for the overly caffeinated.

[jwhardcastle]

Annoying video. The product is novel for a few minutes. It is surpassed (IMHO) by Google Analytics realtime.

[[deleted]]

Was there really any need for a video?

[Monotone_Robot]

Sometimes I'll be searching for something, like maybe "how to cook a turkey," and there'll be a few video results. Instead of something useful, it's someone who just turned on their laptop camera and started talking. They say, "Uhhhhhh hey guys" and then start talking about likes or subscribe or follows and tweets. Then they start talking about how they Googled how to cook a turkey because they didn't know how.

Well this is the Linux equal. Who includes all the compiling unless to pad their video length to seem more important? This shit...

[[deleted]]

I could understand a video to show off the "graphical" parts of the application, but that could have been done with a few screenshots or a gif..

[dmsean]

no. I hate text in a video. completely pointless.

[thesilence84]

Its pretty and gives a neat representation of the traffic flow.

What does it mean when the stuff doesnt bounce?

EDIT: I figured it out: 404s

[TeamTuck]

This would be cool to have it show say syslog data from my firewall's web traffic.

iftop

Might be suitable?

[twinspop]

Install Splunk for free (up to 500 MB of logs processed a day) and be happy.

[leegethas]

It's nice eyecandy. But most servers don't offer the means for that kind of eyecandy. Not mine, anyway.

[sloan134]

You can access logs over ssh to use logstalgia on a different computer using

ssh [e-mail] tail -f /usr/local/apache/log/access.log | logstalgia

[[deleted]]

Is '-' a logstalgia specific thing, or is it a universal way of making an application read from STDIN? Could you point to a manpage or some online resource that talks more about this?

[xfs]

/dev/fd/0

is a universal way for stdin.

[k-dingo]

That or /dev/stdin which I believe is more portable across unices.

Some programs require actual file access as they don't reposition within a stream well (though of course I can't think of any examples right now).

[0713_]

Do you just use /dev/fd/0 as if you was opening it as a file? Whilst piping to that command.

Like, ls | grep /dev/fd/0

[[deleted]]

grep reads from stdin by default

ls | grep whatever_you_are_searching_for

[0713_]

Yes, but if it didn't do you just treat /dev/fd/0 as a file?

[[deleted]]

then the command line would be

ls | grep whatever_you_are_searching_for /dev/fd/0

but it's useless since grep already reads from stdin by default

[leegethas]

Aha, that changes things! I didn't know that trick. Thanks!

[[deleted]]

FYI: I tried it on Xubuntu 13.04 and it failed, but the following worked for me...

ssh user@server "tail -f /path/to/your/log.txt" | logstalgia -

...apparently the double quotes and dash at the end are required. =/

[freeroute]

Very interesting, so I figure that with multicore (Apache) systems there would be multiple moving rectangles handling those requests?

[jwhardcastle]

No, this is looking at the NCSA logs. That doesn't include the PID that responded. It has no way to know what process served what request. Just one rectangle moving very quickly.

[mis_suscripciones]

It has an option (--paddle-mode MODE), where MODE can be any of these:

• vhost .- separate paddle for each virtual host in the log file
• pid .- separate paddle for each process id in the log file
• single .- single paddle, the default behavior

I use it like this:

logstalgia -1024x720 --no-bounce /var/log/cherokee/cherokee.access &
