I particularly like the "cron job to update crontab." Reminded me of when I told Genie Timeline Pro -- a continuous backup application -- to include my entire user folder. Turns out, that's where it stores its logs. Had a bit of trouble finishing the backup.

Having just explained my childhood misconceptions of large named numbers in another comic explanation thread1, the Cron updating of Cron puts me in mind of the idea of a Cron job that reset its own timing to wait twice as long until its next occurence, each time it runs.

For why..?

...I'll tell you in a dozen iterations. ;)

1 <prefix>illion=power(10,3*2<prefix>) in a mixed modern parlance, "mi-"==1, thousand being zero in this context.

Funny you should suggest that, since the Windows7 GodMode folder has been found to provide a few security holes.

That sounds fun. Seems like it might be easier with "at," though. A self-modifying shell script whose last line calls `at -f "$0" "Now + $t minutes"` should do it.

Edit: This works, although you have to hardcode the file path:

Code: Select all

#!/bin/bash
printf %s\\n '/^t=/!awk -F= '\''{print "t=" 2*$NF}'\' x | ex /path/to/this/file
t=1
at -f /path/to/this/file "now + $t minutes"
There's no such thing as a funny sig.

It's not the same. "Safe mode" in this context would be more like: "safe from (most) problems introduced by installed drivers and user programs".

"God mode" would be: "Unrestrained from any system-imposed constraint, able to wreak havoc on the whole operating system and possibly, through direct user access to the hardware at ring 0, to destroy the computer itself from the inside, either by accident or malice."

Using recursive regexes as supported by perl, it is indeed possible to construct a regex to match EBNF:

Code: Select all

^\s*(?:(\(\*.*?\*\)\s*)*[A-Za-z][A-Za-z0-9_]*(?:\s+[A-Za-z][A-Za-z0-9_]*)*\s*=\s*(((((?1)*(?:[1-9][0-9]*\s*\*\s*)?(?1)*(?:[A-Za-z][A-Za-z0-9_]*(?:\s+[A-Za-z][A-Za-z0-9_]*)*|(?:\[|\(\/)\s*(?2)\s*(?:\]|\/\))|(?:\{|\(:)\s*(?2)\s*(?:\}|:\))|\(\s*(?2)\s*\)|'[^']+'|"[^"]+"|\?[^?]*\?|))(?:\s*(?1)*-\s*(?5))?)(?:\s*(?1)*,\s*(?4))*)(?:\s*(?1)*[|\/!]\s*(?3))*)\s*(?1)*[;.]\s*(?1)*)*\s*$


Or expanded for readability ( :P ) and commented:

Code: Select all

/^\s*
    (?: # Rule
        (\(\*.*?\*\)\s*)* # Comment (?1)
        [A-Za-z][A-Za-z0-9_]*(?:\s+[A-Za-z][A-Za-z0-9_]*)* # Identifier
        \s*=\s*
        ( # Definition List (?2)
            ( # Single Definition (?3)
                ( # Term With Optional Exception (?4)
                    ( # Term Without Exception (?5)
                        (?1)*(?:[1-9][0-9]*\s*\*\s*)? # Numerical Repetition
                        (?1)*(?: # Syntactic Primary
                            [A-Za-z][A-Za-z0-9_]*(?:\s+[A-Za-z][A-Za-z0-9_]*)* # Identifier
                            |(?:\[|\(\/)\s*(?2)\s*(?:\]|\/\)) # Option group
                            |(?:\{|\(:)\s*(?2)\s*(?:\}|:\)) # Repetition group
                            |\(\s*(?2)\s*\) # Group
                            |'[^']+' # Single quoted string
                            |"[^"]+" # Double quoted string
                            |\?[^?]*\? # Special sequence
                            | # Empty string
                        )
                    )(?:\s*(?1)*-\s*(?5))?
                )(?:\s*(?1)*,\s*(?4))*
            )(?:\s*(?1)*[|\/!]\s*(?3))*
        )
        \s*(?1)*[;.]\s*(?1)*
    )*
\s*$/x;


I don't guarantee it correct, but it works for the few snippets from the I tested it on (mostly from the wikipedia page).

Most recent search: do people often search in full sentences?

Which got me 0 useful results, so I'll ask here: do you often/ever type or say a full sentence to a search engine?
I'm still used to searching by keywords, but one of my housemates is adamant about using whole sentences; both because voice-control needs to parse sentences anyway and it's likely that others searched for the same sentence before and bumped the right result to the top.

For sure my search strategy has gradually co-evolved as Google has got cleverer. I used to use keywords and do things like putting them in decreasing order of importance, but you get the increasing impression that the search engine is doing its best to understand what you're asking, so it makes more sense to ask it in English. Certainly it seems that one way or another it's recognising the relationships between the words of the query, and presumably this process is helped by adding in prepositions, conjunctions etc. It's probably even worth including words like "the", which Google used to tell you it was ignoring: although it's almost certainly ignored for the first stage of finding pages, there are presumably stages of filtering and ranking during which the semantics of the sentence are taken into account. Also, even without quotes, it will favour pages in which the phrase appears verbatim. So, for example, the distinction between taking a piss and taking the piss is important and the two phrases will return different results (admission: I haven't actually tried!). All this means that I tend to end up typing in complete phrases or sentence fragments.

The wrong is truly with me today. To take a piss is simply to urinate, so I thought the two would give quite different results. As you say, it's kind of weird that the results are different - so it doesn't ignore a/the - but not in a meaningful way.

Many of the things I search for are question titles on Stack Exchange (or similar), so full sentences are usually appropriate and useful.

My confidence in Google's semantic cleverness was somewhat reasserted by searching for "the batman" (sans quotes) vs. just "batman" and seeing that the fairly minor 2004 series incarnation was indeed prioritized in the first search and not the second. But yeah, I would have expected it to successfully distinguish between the two very different takings of pisses. I suppose that "taking" and "piss" are low-frequency-enough words that the wealth of internet resources available for taking the piss are invoked even if the article is inexact.

If you're in, or have access to a proxy server that convinces the BBC that you are in, the UK, there's just been an interesting documentary on Radio 4 about the ethical and societal impacts of the Google search algorithm,

BBC Radio works outside the UK and its IP blocks - it's just the TV programs you can't access. That apparently doesn't stop the mobile iPlayer from being a horribly broken piece of shit for everyone, but ... yeah. Going to give this a listen when I can get it to work, but I'm not too impressed with paranoia as an opening premise.

Tangental connection to the story going around about Facebook curating their news "trends", at least in terms of opaque biases in an apparently transparent system.

Whadya know, I'm listening to my pre-record of that programme right this moment... Yup, I'm multitasking! Ears and eyes attuned to different media.

It's not a hatchett piece. Might not satisfy paid-up Googlephiles, and neither will extreme Googlephobes think it's represented their views, so probably fairly balanced in its mere half-hour treatment of the subject.

I don't like the loss of the "dowload/don't download" toggle switch (to start/stop whethere queued items are being sought or left queued, perhaps because my current WiFi wouldn't appreciate the streaming) having disappeared, an update or three back of tbe Android App. A big loss that I haven't managed to contact anyone to complain about, yet.

But it's not 'horribly broken' for me, most of the time. The only issues I currently have is (long and offer-topic)
Spoiler:
(apart from corrupted/terminated downloads because it's been grabbing a download and the network drops/thows a hissy fit, which happens with other media aggregators where you don t have use on/off download control, which can be worked around) is an oversensitivity to the tablet clock being corrected, as it needs to be every month or so, at which point it seems to presume I've been trying to fool the expiry mechanism (like you used to be able to, if you had just half an hour to listen to an old, hour-long programme) and seems to invalidate every single download.

(It then crashes, on trying to play anything, which is probably not the intended behaiour. Nor that I need to make manual notes of everything that I delete, so I can repopulate the downloads from scratch to get back to where I was.)

So I just leave the clock until I've got no/few programmes downloaded, and never when offline and out of wifi contact.

Maybe I'm lucky. - er.
But, if he hasn't already been mentioned on these forums, while I'm here can I just recommend the works of John Finnemore,. I was relistening to his Souvenir Programme, a few minutes ago. It is currently partially available (three episodes from series 3, as I type) and I think he's probably got an audience amongst xkcders. The Radio Randall, in many ways..?

Edit: Strange - "Search found 1 match: Finnemore", and that's this message. I would have bet money that he's known around here. Unless the Search is still a bit off. (This thread is not on my Egosearch...)

clock speed jumper sample rate


This has lots of real-world applications. First, due to the way regulatory agencies measure electromagnetic interference, it's advantageous to actually vary the clock speed within a certain range, which spreads out the interference over more frequencies. It's called "spread-spectrum clock" and has been popular for several years. https://en.wikipedia.org/wiki/Spread_sp ... generation

Second, by purposefully varying the clock speed, you could surreptitiously transmit information without additional hardware, assuming the receiver was able to pick up the interference. Proof of concept plays music over a standard AM radio by using leakage from a VGA cable: http://www.erikyyy.de/tempest/

Third, way back in the 486 era, I discovered my desktop didn't crash if I moved the clock jumper while it was turned on. It was a 40MHz chip so it had a fan, but if I clocked it down to 8MHz (the lowest speed selectable by moving a single jumper), it ran so cool the fan was totally unnecessary. So for most of my BBSing, I'd run super slow and unplug the fan, which both lowered power consumption and quieted the system significantly. Also at 8MHz, some harmonic of the system clock was audible as interference in my FM radio while tuned to a weak station that happened to be my favorite. So if the modem was still downloading, the UART ISR was firing periodically, and I could hear that alongside the music. Turn off the monitor and take a nap. When the download would finish, the modem would go idle, the interrupts got less regular, the noise would change, and I knew to turn the monitor back on and handle my downloaded file. Easy peasy, dynamic clocking and EMI-based system performance monitoring in 1994. :)
