Cisco Blamed A Router Bug On 'Cosmic Radiation' ( 98

Network World's news editor contacted Slashdot with this report: A Cisco bug report addressing "partial data traffic loss" on the company's ASR 9000 Series routers contended that a "possible trigger is cosmic radiation causing SEU [single-event upset] soft errors." Not everyone is buying: "It IS possible for bits to be flipped in memory by stray background radiation. However it's mostly impossible to detect the reason as to WHERE or WHEN this happens," writes a Redditor identifying himself as a former [technical assistance center] engineer...
"While we can't speak to this particular case," Cisco wrote in a follow-up, "Cisco has conducted extensive research, dating back to 2001, on the effects cosmic radiation can have on our service provider networking hardware, system architectures and software designs. Despite being rare, as electronics operate at faster speeds and the density of silicon chips increases, it becomes more likely that a stray bit of energy could cause problems that affect the performance of a router or switch."

Friday a commenter claiming to be Xander Thuijs, Cisco's principal engineer on the ASR 9000 router, posted below the article, "apologies for the detail provided and the 'concept' of cosmic radiation. This is not the type of explanation I would like to see presented to the respected users of our products. We have made some updates to the DDTS [defect-tracking report] in question with a more substantial data and explanation. The issue is something that we can likely address with an FPD update on the 2x100 or 1x100G Typhoon-based linecard."

That's their right. Luckey's right is to speak against Hillary, VR devs' right is to be intolerant to Luckey, a consumer's right is to boycott those VR devs because of their siding with Hillary and so on.

As long as we all have those rights and are exercising them legally it works itself out. It's sad that so much hate is going on but you can't blame Trump or Hillary for that -- it's the state of the world at the moment that created the conditions for it. In a wiser world such conditions would be prevented before Trump or Hillary would rise to prominence, but it is what it is.

While this is absolutely true, it doesn't mean it's good -- in the long term -- for American culture to slide into "I'll boycott anyone I disagree with about anything" mentality, because it reduces social cohesion and increases social friction.

As a libertarianish conservative, I agree 100% with people's free speech, and free speech about others free speech, and economic boycotts about others' free speech. I still lament that it has come to this and hope this age passes quickly. There's a resonant effect that will kick in once the folks who grew up in a "not my president!" post-2000 mentality start having and training kids of their own; if this dumb political intolerance of other Americans doesn't stop, it'll be that much harder to turn around.

We haven't seen a first-world country devolve into civil war. I'd hate to start it now.

If someone was going to die as a result of a malfunction or breach of a system, we'd demand it be air-gapped and have robust CM. There would be hell to pay as a result of failure - think hospital systems. Or military systems.

The thing is, most of the systems businesses use aren't all that important in the grand scheme of things. No one is going to die if Twitter or Walgreens has a breach. Sure, for the individual, this is bad, but you're probably going to get your prescription anyway and having someone impersonate you on your Twitter account is irrelevant.

Cue "assumed breach"...we must assume that systems like Twitter and Walgreens are breached and are leaking data. Therefore, conduct any business with them while insulating yourself from the consequences of said breach.

Kursk was a strategic defeat, to be sure, but it was a tactical defeat as well. The main reason is that the gathered German mobile force was directed at a salient which had been basically turned into a fortress by the Soviets. Many lines of defense were constructed including a deep line all the way back at the Don - showing the Soviets were not convinced they could stop the Germans in the salient. Much superior results could have been had by choosing a different axis of attack in a different sector, rather than biting off Kursk after it had been fortified. The main reason why is that most casualties were caused via encirclement rather than frontal tank combat versus a staunch defense.

It is only the superior German units and tactics that resulted in the high Russian casualties you describe. The Russians could afford the loss (in purely practical terms), while the Germans could not replace their losses. Then, the Germans had their forces dispersed by the requirement to form a defensive line in Italy after that nation's collapse and armistice.

Richard Overy's "Why the Allies Won" is a good synopsis of the recent scholarship on this, while Chris Bellamy's "Absolute War" is a less readable book overall that covers the same material in more detail. Books from before 1990 (example: Albert Seaton's "The Russo-German War") had very little detail about what actually happened at Kursk from the Soviet side. In regards the mistaken attack on Kursk, Mellenthin's wonderful "Panzer Battles" or Manstein's "Lost Victories" are pretty conclusive on this score.

They've lied about their news feed provenance, they've lied about censorship, now they lie about video statistics. The whole site is a cesspool. The day is rare when someone isn't asking me about a factually inaccurate FB ad trying to scam old people.

Taking it offline would benefit all of humanity. It's as bad as e-mail at this point.

Actually, he was genetically far better off, and this explains why he was able to spearhead a European domination of the Western Hemisphere. All that inherited resistance to crowd diseases from Eurasia - smallpox most significantly, but all the rest of them, too. In fact, the only areas Europeans didn't dominate in the Western Hemisphere were areas where indigenous diseases prevented their dominance, such as the Amazon basin.

I'd also point out that armies do the same thing - they attack at dawn because the enemy is at low ebb at that time. The counter-example is Kursk in 1943 - and the Nazi attacker lost, though not entirely because they launched their attack at 3pm.

It's also why armies get their people up really early in the morning.
