I was reading a article about a database programmer, who after learning he was about to be fired put six lines of code that would delete everything on the company's main computer, costing them millions and putting them out of business.
7/30/96
F:
F:\LOGIN\LOGIN 12345
CD \PUBLIC
FIX.EXE /Y F:\*.*
PURGE F:\ /ALL
Can someone tell me how this code works and what language it is programmed in? I assume SQL?
It's just some (DOS?) shell commands. The point of the example isn't how clever the code is. The exact opposite, actually: apparently anyone with basic knowledge of this company's systems, and a beginner's knowledge of the DOS shell, could have done this. (Notice in particular that their admin password was "12345".)
The example may as well be made up, and possibly is.

I need less to display a file without any additional formatting characters.
I found the --tilde option, which got rid of the ~ characters.
Now I only need to get rid of the:
(END)
or
<filename> (END)
at the and of the page.
I am happy to recompile less , if somebody can suggest what needs to be changed in the sourcecode.
I am using less 487 on Debian 10.
You configure the prompt with -P, for instance, this will no longer show the filename or END (but still the :):
less -P ''

Hail all:
Though I am 52, and active with computers since 1986 (those were more oversized calculators, to be correct), i have no idea what is meant with Form Data.
I know, I know, this is insane, but i just never came across this before.
Might be, I DO know it, but by a different name, maybe Dutch.
Still I am quite stuck, to be quite honest.
Tried to google it, got heaps on information as to how to clear it, restore it, save it, unsave it, ... , but nowhere an in-depth explanation of what is meant with form Data.
Now, I am building a Batch File, for speed-cleaning of certain data, when my Firefox starts to get slow ... .
Came across the "erase Form Data" command, but nae clue as to what Form Data is.
Thank you.
Ben
That rundll32 command only applies to Internet Explorer and will not touch Firefox.
Anyway, form data is data entered into html forms like your name, address and telephone etc. These form fields are edit boxes, check/radio buttons and drop-down selectors.
Firefox has its own setting to clear form data when you close the browser. Form data is very low on the list of what slows down your browser...

When running UserMailer.new.perform, my mailer is sent and I get an email almost right away, but when I use UserMailer.perform_async, it spits back an object number and I never receive an email.
Can someone please tell me why this is happening and what the difference between these two methods are?

I am trying to take a look at the status of r7rs large but I cannot find any information
in scheme reports page, etc, just a talk from 2013. I searched around with google without success as well.
Is it still alive?
Where can I find information?
What would be the tentative date?
What is the progress at this point?
Thanks.
You can read about the R7RS process on the R7RS working group wiki. R7RS-large is listed under the "Working Group 2" section of the front page.
In particular, look through the StandardDocket and ConsentDocket sections. Standard docket is for stuff that's under discussion (and eventual voting). Consent docket is for generally-uncontroversial stuff that's likely to get into R7RS-large without having to be voted on.
There is no firm timeline that I am aware of (though I'm not part of the working group and do not speak for them). The standard docket is quite long, though, and they will have to process through most/all of it before you have anything that you can call R7RS-large.

I would like a shell script that does a quick upload/download speed check of my current connection, similar to the functionality of the website speedtest.net, but without the flash and the fancy graphics. It doesn't need to be super fancy or accurate, just give me a rough idea of what I'm working with. Any languages that are commonly supported in any shell will be fine.
wget --output-document=/dev/null http://speedtest.wdc01.softlayer.com/downloads/test500.zip
wget-ing a large file is the way to do it. ie the above
you will see something like this:
3% [> ] 19,207,452 1.38M/s eta 5m 43s
according to this test mine is a 1.38m/s
