...You can check if you've been scanned for exploitable CGIs using something like (adjust apache logs path accordingly):

grep cgi /var/log/apache2/access*|egrep "};|}\s*;"

And you can check if your bash is vulnerable using:

env x='() { :;}; echo vulnerable' bash -c 'echo Testing...'

If 'vulnerable' appears, it is.

Thank you for the grep. When I ran it on my little web site I found I had been probed. The log line looked like this: - - [25/Sep/2014:01:53:59 -0400] "GET /cgi-sys/defaultwebpage.cgi HTTP/1.0" 404 224 "-" "() { :;}; /bin/ping -c 1"

I wonder what would happen if we all starting pinging that last IP address.

A budget is a statement of what's important. (A more-or-less clerical friend of mine said that the most important theological document a church has is its budget.) If a company is required by law to do something, then that something will be held to be important, and an unwillingness to devote the resources to doing it will not necessarily fly with the judge.

That is why you hire the judge's granddaughter. The judge will be reluctant to declare the effort insufficent, because she won't want her grannddaughter to lose her cushy job.

And within a few days the girl will file a report informing about the volume of work she is facing and the number of subordinates she needs to hire to get the work done, along with the suggested salary for herself and the subordinates. All of it to be paid by Google, of course.

And her supervisor will reply that there is no money in the budget for hiring more people, so she should do the best she can with the resources she has been allocated.

I'm still saying you are the competent exception. If you took one class in public speaking and are an expert, you are not the standard student. You are a savant. Where I worked we had technical editors, visual editors, and general content people who went to school to learn how to communicate ideas professionally and if you are performing at their level you are possibly in the wrong line of work.

Just because I can prepare a presentation that people will listen to does not make me a professional. When I started doing it, the ability to communicate with customers effectively was considered part of the normal duties of a software engineer. Today's professional communicators will invite you to a free dinner and sell you a timeshare. I'm not in their league.

....A trained communicator in the loop is a very good idea.

I would disagree with you only on this point, and only slightly. I would say that a trained or experienced communicator in the loop is a very good idea. I have never had any formal training in communication, beyond a class in public speaking in summer school.

I have a similar background, except we had an editor who approved all slides. She was a ruthless, heartless person who lacked a soul while wielding a red pen like calvaryman's saber as she edited. In other words, the perfect editor. To this date, I cringe at a presentation withe text less than 16 pt and more than 20 words on a slide. When I see a sentence with a period on a slide I remember her admonition "Women have periods, slides don't."

I would liked to have met her. As far as I know my slides never had any approval process, but I think your editor would have liked them.

I started doing presentations back in the days of 35-mm slides. I didn't have to prepare them myself—I sent the text to the corporate slide presentation department, and they sent me back the slides.

I prepared my presentation by first writing out what I wanted to say, word for word. I then distilled that document into a few topic lines, which I had made into slides, generally about three topics to a slide. At this point I discarded the original manuscript. When I gave the presentation I glanced at each slide to remind me of what I wanted to say, then spoke extemporaniously.

Today I prepare the slides myself using LibreOffice Impress, the free equivalent of Microsoft PowerPoint, but I use the same method.

At first I wanted to write off your post as just typical, cynical slashdotterism. But I re-read it and - well, I realize that you are probably right, particularly in the IT field (it could be argued that if you want to work in academia, school names _do_ matter).

Reading your post carefully, I see you aren't saying that "college is worthless, blah blah blah" but rather that the differences between the universities for undergrad ain't what they used to be. As another commenter here noted (paraphrasing) information has been liberated by the Internet so University isn't the only way to attain subject matter knowledge anymore, closing the gaps between schools.

However, I continue to believe that if a person goes through 4+ years of accredited university experience, learns how to follow directions, learns how to deal with smart people & foolish people, and discovers that they have a passion for something (be it computer science or otherwise) is a person better prepared to be effective in the working world than otherwise. And if that's university's main benefit, then dammit I guess I have to agree that it matters less where you do it.

Grad school is probably a different story but for undergrad & the kind of jobs you will be getting with an undergrad degree - I think you got it right.

To provide a different perspective, I had the incredible good fortune to attend a top-tier university. In my four undergraduate years, I got to program four of the five computers on campus: an IBM 7090, a Burroughs B5000, a DEC PDP-1 and a DEC PDP-6. After leaving the university, I spent the next 40 years working in the computer industry. I doubt I would have been able to do that had I attended a lesser institution with no approachable computers. Today computers are everywhere, but I suspect there is some other technology present at the top-tier universities that will be very important in the future.

Also, I got to know and work with some of the most intelligent people in the world. That experience is very humbling: I used to think I was pretty smart—I learned I wasn't. That's a valuable life lesson.

Comment: end of line codes (Score 1) 729

Probably the same way that most popular operating systems store text files as a list of lines separated by newline characters, encoded as 0x0A on UNIX or Windows but 0x0D on Apple II or classic Mac OS. VMS is an exception in that its "non-stream" text files have each line prefixed by its length.

The conventions for line endings are based on history. DEC's operating systems and operating systems descended from them use CRLF because that is what you had to send to an ASR-33 teletype at the end of an output line. UNIX and its descendents use NL, which has the same code as LF, because they were targeted at later printers.

By the way, the VMS record length field was 16 bits, avoiding the limitation of 255 characters in systems which used only 8 bits for the string length.

Comment: Re:Null Terminated Strings (Score 1) 729

- strings terminated by a binary zero rather than their physical size. Who the hell thought that would be a good idea? Well, age old argument. Basically a matter of taste or sadly a historical "evolution".

I'm pretty sure null-terminated strings come from the days of punch cards/punch tape where an unpunched area is read as null (binary zero). Wherever the data-entry clerk stopped typing was the end of the string and the string could be appended to latter (impossible with a non-zero end-of-string symbol or a string length in the header which can't be rewritten on card/tape).

Actually, an unpunched column on a card was a space. You are right about paper tape.
