Drawing the border 6809x times doesn't sum up to the exactly one second blinking rate you can verify by watching this recorded video: http://www.youtube.com/watch?v=PlFSH-cDVdA - I tried to calculate how the rate was from the 6809x times given in the article, using both the 68000's clock speed and the PAL frequency of 50hz, but what I get makes little sense. So I'm adding a "citation needed". -- Paniq (talk) 16:51, 16 May 2009 (UTC)

Someone should add all Guru Meditation codes.

Redirect

I created the redirect for Grim Reaper (Screen of death). Junkcops (talk) 23:34, 16 November 2008 (UTC)

Image

Image should be replaced per Wikipedia:Image_use_policy#Animated_images, the blinking box doesn't really add anything to any greater understanding of the error message itself.--Crossmr (talk) 02:51, 25 January 2009 (UTC)

The blinking red box animation is essential part of this error message. I's a historical error message design, nowadays we don't using this kind of visual features. This animated gif is an authentic demonstration, we must keep it. (Wikipedia:Image_use_policy#Animated_images is not about banning all animated images.) Madacs (talk) 15:07, 13 October 2010 (UTC)

Guru Meditation on The Pirate Bay

I just got an error message from The Pirate Bay website. The Error was:

Error 503 Service Unavailable

Service Unavailable Guru Meditation:

XID: 77159181 Varnish

...With the word "Varnish" a link to http://www.varnish-cache.org/

It appears that Varnish uses Guru Meditations n error messages: http://www.mail-archive.com/varnish-misc@projects.linpro.no/msg01671.html

Worth adding to the article? Don't know. Interesting, though.

72.251.91.111 (talk) 18:11, 9 August 2009 (UTC)

I got one on a totally honest and non dubious site as well (as an old Amiga man it warmed the cockles of my heart *g*), they also use Varnish so I think its safe to say that some on the Varnish team used to have an Amiga. --IceHunter (talk) 17:51, 22 February 2010 (UTC)

Already covered in the first paragraph. Lostinlodos (talk) 20:02, 22 February 2010 (UTC)

And someone has removed it. Adding back now... Stuinzuri (talk) 09:17, 18 December 2011 (UTC)

Amiga Recoverable Alert

I think this article should be merged into Guru Meditation, since it's pretty redundant (a Recoverable Alert is a type of Guru Meditation, albeit recoverable). Schala ★ 04:34, 11 June 2010 (UTC)

I agree. They are both on the Amiga, but one is recoverable, like a stop error or BSoD. Wizkid5059 (talk) 17:23, 11 June 2010 (UTC) Maybe you're right. ComputerAccount (talk) 22:34, 6 July 2010 (UTC)

Unrelated part to article

There is the unrelated section in this article called "Commercially available guru error handler on the old Amiga os".

Varnish

Steam's Varnish cache server crashed and displayed "Guru Meditation:" and "XID: ", followed by a number. If this is the normal error message of Varnish, this could be noted. --83.189.63.67 (talk) 02:19, 13 November 2011 (UTC)

It is. Someone seems to have removed it for whatever reason. I'm putting it back in. Stuinzuri (talk) 09:16, 18 December 2011 (UTC)

got one of these on some webpage just now, but it said "guru mediation", not "meditation". "error 503 first byte timeout [...] guru mediation [...] varnish cache server" k kisses 16:51, 26 January 2020 (UTC)

Removed Old/Misleading External Page

There was a link called 'Guru Meditation Explained' at http://scotek.org/guru.html. I removed this because I could find nothing even vaguely related to the topic of the article at the referenced page. — Preceding unsigned comment added by 76.103.48.252 (talk) 05:59, 10 April 2012 (UTC)

Rollback Request

On 13 July 2013, IP editor 2602:304:AF53:3E99:2C4B:F6A:56CB:384B made this edit with edit summary "FIXED." Instead of fixing something, the IP editor copied this revision from 18 May 2008 into the article (removing only the Trivia template). The article needs to be rolled back to this revision of 27 June 2013‎. --82.170.113.123 (talk) 17:00, 18 August 2013 (UTC)

I've done it myself. --82.170.113.123 (talk) 17:08, 18 August 2013 (UTC)

I just saw this at a website

https://i.imgur.com/HLUyKrI.png --fs 16:32, 11 May 2020 (UTC)

It appears to be the Varnish cache server, https://varnish-cache.org/ --fs 16:33, 11 May 2020 (UTC)

URL is 404

Not surprisingly, the URL for "Joyboard Controller" goes to a missing page. — Preceding unsigned comment added by 68.109.194.172 (talk) 17:02, 4 June 2020 (UTC)

Looking at the archived version of the page, there wasn't much there that was relevant to this page, just a table with three games it was used in. I'll remove it. Opencooper (talk) 18:05, 4 June 2020 (UTC)

A source, i think

At the moment, khan academy is giving out a "Guru meditation number" page contents are as follow:

Error 503 first byte timeout

first byte timeout Guru Mediation:

Rearranged article content to put non-technical content at the top, and a few words added about Varnish to help baffled surfers.

• Rearranged article content to put non-technical content at the top.
• Also inserted at the top a few words about the (rare, but widely seen when it occurs) internet website 'Guru Meditation' error message thrown by Varnish (popular open-source HTTP accelerator for content-heavy websites.)
• Clarified difference in spelling between the Amiga message and the Varnish message. (and helps this page be more visible in Google results for baffled surfers looking for an explanation for the error message thrown by their favourite website)
• No content removed. Minimal additions.

RedTomato (talk) 10:45, 8 June 2021 (UTC)

Varnish does not and has never used the incorrect “mediation” spelling, cf. the original commit and the current version. DES (talk) 13:11, 8 June 2021 (UTC)

Are you sure? Here's a snapshot. -- HLachman (talk) 15:33, 8 June 2021 (UTC)

Yes, I'm sure. I was one of the original authors. DES (talk) 09:19, 9 June 2021 (UTC)

In what may be a first ever for Wikipedia, you are BOTH correct! It appears that the code uses the "meditation" spelling, but the error message displayed to the surfer uses the "mediation" spelling. See this discussion in the Register for verification. (Search the page for "mediation"). I'd appreciate the note about the spelling variant being put back in (and it will help baffled surfers find this page). RedTomato (talk) 22:12, 8 June 2021 (UTC)

No. I am right and they are wrong. Attributing this misspelling to Varnish is factually incorrect and an insult to Poul-Henning Kamp and myself, who wrote the damn thing. DES (talk) 09:19, 9 June 2021 (UTC)

If by "they" you mean me, I'm pretty sure I did not make a false statement. I did not attribute the alleged misspelling to Varnish. At present, it appears that Fastly is the party that is attributing their alternate spelling to Varnish (per the snapshot I linked above, plus my link to the Fastly glossary, below). I don't know whether Fastly's fork of Varnish should be called "Varnish" or not (just like I don't know if a fork of Linux should be called "Linux" or not), and this probably isn't the place to debate that issue, or whether an "insult" or other harm occurred (perhaps an attorney can advise you on whether Fastly is at fault in the matter, if that's your issue). The purpose of the talk page is to discuss how to improve the article... which is OK at the moment, in my opinion. -- HLachman (talk) 09:51, 10 June 2021 (UTC)

Ars Technica now has an article showing the Guru Mediation spelling. I regard Ars as a reasonably authoritative source. Also there have been some reverts by editors (rightly) questioning the noteworthiness of the alternate spelling. As there have been multiple reports across global media of this morning's downage, I think this is tipping over into just marginally notable enough to make a very brief note of the Guru Mediation spelling. RedTomato (talk) 22:55, 8 June 2021 (UTC)

I support the mention of the alternate spelling. The Fastly online glossary clarifies that it's a Fastly thing by design, and not an accidental misspelling. -- HLachman (talk) 06:19, 9 June 2021 (UTC)

Citation Should not be Needed

There in content on this article that reads: It is, however, still recommended to reboot as soon as possible after encountering a Recoverable Alert, because the system may be in an unpredictable state that can cause data corruption.

In the software development world, this is rather common knowledge. After a low-level exception occurs (especially if it involves memory or hardware) you CANNOT guarantee the state of the rest of the software system. It does not matter if this software system is a basic Hello World application, or a full-blown operating system. For example, if you were working with a spreadsheet application and it encountered a memory access violation, you can no longer guarantee the values that were already loaded or entered into it. If the memory operation that caused the exception was a WRITE operation, something could have already stomped on the memory where one or more of those values were stored, rendering them invalid. If the user continued on and saved the in-memory data to disk, they may now have corrupted the data in the spreadsheet without knowing it. Loss of work (i.e. data loss) from stopping the application is preferable to data corruption in this case. After all, what would you prefer?

Saying this needs a citation is like saying one is needed for "it is generally a bad idea to dereference a NULL (or nullptr) pointer" in software circles or saying one is needed for "the clutch pedal in a car is generally used to engage or disengage the clutch" in automotive ones. Devs know that continuing past an exception like that is A Bad Thing. JamesRTwine (talk) 18:18, 30 August 2023 (UTC)
