Rogers is actively throttling bandwidth for World of Warcraft players

In what isn’t really a surprise, Justin Olivetti reports on how Canadian WoW players have been suffering from deliberate throttling:

If you play World of Warcraft in Canada and were wondering why your connection seemed a bit slow, it turns out there may be a good explanation: Rogers Communications has been deliberately throttling the game across the country.

[. . .]

Rogers said that it was Blizzard’s use of BitTorrent to deliver updates that triggered the throttling, and said that customers who disabled this setting — as well as any other peer-to-peer applications — would not see a slowdown in speed. “Rogers will engage our customers to ensure they are aware of these recommendations, while continuing to work on a longer term solution,” a spokesperson said.

Panic-mongers still hard at work over Fukushima

Lewis Page is less than impressed with the media’s ongoing coverage of the Fukushima reactor clean-up:

The situation at the quake- and tsunami-stricken Fukushima Daiichi nuclear powerplant in Japan was brought under control days ago. It remains the case as this is written that there have been no measurable radiological health consequences among workers at the plant or anybody else, and all indications are that this will remain the case. And yet media outlets around the world continue with desperate, increasingly hysterical and unscrupulous attempts to frame the situation as a crisis.

[. . .]

Nonetheless, in the hyper-cautious nuclear industry, any dose over 100 millisievert is likely to cause bosses to pull people out at least temporarily. Furthermore, the three workers had sustained slight burns to their legs as a result of standing in the radioactive water – much as one will burn one’s skin by exposing it to the rays of the sun (a tremendously powerful nuclear furnace). They didn’t even notice these burns until after completing their work. Just to be sure, however, the three were sent for medical checks.

So — basically nothing happened. Three people sustained injuries equivalent to a mild case of sunburn. But this was reported around the globe as front-page news under headlines such as “Japanese Workers Hospitalized for Excessive Radiation Exposure”. Just to reiterate: it was not excessive.

Reporters clamoured to know more — in particular how could the water in the basement of the reactor building have become so radioactive — no less than “10,000 times normal”. One might note that in general radiation levels 10,000 times normal mean that you could achieve a tiny fraction of an extra percentage point of cancer risk by being exposed for a fortnight or so.

[. . .]

Then there’s the matter of the tapwater in Tokyo. Two days ago, levels of radioactive iodine-131 were found in the city’s water which were above the safety limit for baby milk calculated on the basis of a year’s consumption: in other words, if babies drank such water for a year constantly they would have a tiny, minuscule extra risk of thyroid cancer.

[. . .]

There was never any chance whatsoever that levels of iodine-131 in the tapwater would remain noticeable for a year, which is what would be necessary for any effects at all on the city’s babies. It was really quite irresponsible of the authorities to recommend that infants shouldn’t drink it. (One can’t help noticing that the first such recommendation reportedly came from the city authorities, belatedly followed by the national government. The Tokyo city governor is from the national opposition party and is facing a tough re-election battle. He had previously sought to use the Fukushima situation to cast his political rivals in a bad light over the deployment of Tokyo’s elite Hyper Rescue firefighters.)

I’d also recommend that you keep an eye on the World’s Only Rational Man for his professional take on what the media is currently panicking over at any given moment:

If modern “journalism” wasn’t the single most incompetent industry in human history we wouldn’t be pulling our hair out over this. Where’s the followup to the reports of Cl-38?

How freakin’ incompetent is the entirety of Big Media?!

You’ve had two weeks to learn a minimum about this subject you obsessively “cover”.

“But…but math is hard!” you whine? Then find some dad-gum folks who do this crap for a living rather than cultivate ivory tower media-hounds.

Sorry. Forgive the venting. Tired and P.O.ed.

Apparently going beddy-bye to the thought of runaway nuclear excursions isn’t warm milk and happy stories. Monsters Inc. could have stayed in the scaring business if they’d taken lessons from The Media.

This blogging day began with concern about neutrons. And so it ends.

I wish we still had reporters.

Because I hate journalism.

Once again, wormme is a radiological control technician, so he actually knows what the hell he’s talking about, unlike just about everyone “covering” the news.

Over-analyzing the Bayeux Tapestry

Filed under: France, History, Humour, Technology — Tags: — Nicholas @ 10:39

Chris Mellor looks at the Bayeux Tapestry from a data storage perspective:

The Bayeux Tapestry, the victor’s view of the events, was finished in 1077, ten years after it was begun, making it 934 years old. At 224.3ft long and 1.6ft wide the total surface area is 358.88sq ft.

Our understanding is that the Tapestry features 45 to 48 threads per inch which gives us a resolution approximating 47dpi with a colour depth of 8, ignoring later repairs. Thus, in information terms, the tapestry contains 2.429MB of information, assuming 1-bit per colour, 47dpi, and a 51,678.72 square inch surface area.

From the writing point of view it took ten years for English (Saxon) seamsters, seamstresses or embroiderers to write this 2.429MB of data, which must be some kind of record. Assuming an eight-hour, 350-day working period for these ten years, that implies a write bandwidth of 10.84 bytes/hour; a spectacularly slow data rate in information transfer terms.

What makes it worse is that there were multiple parallel write heads — seamsters or seamstresses — and we could envisage a team of five on average, meaning each write head in this theoretical Bayeux Tapestry archiving model wrote at a rate of 2.168 bytes/per hour (17.344 bits/min). A truly amazingly poor information write bandwidth from our IT viewpoint, but a blur of flickering needles and fingers seen from the embroiderers’ seat.

QotD: One-minute Imperialism

Filed under: Africa, Military, Quotations — Tags: , , , , — Nicholas @ 10:17

It is the height of recklessness, a kind of blasé barbarism, to start a war without knowing what the war is for. We are witnessing the transformation of Libya into a giant laboratory for a zany, unpredictable experiment to see what happens when you mix Tomahawk missiles with a volatile Arab uprising. It makes even the ill-considered debacles in Iraq and Afghanistan look like the height of rationality in comparison.

The made-up nature of the war, its speedy and brainless cobbling together by Western leaders keen to make a quick point by firing a few hundred missiles at Gaddafi, explains why the so-called Western alliance is so spectacularly flimsy. This must be the most shortlived alliance in human history. It lasted about 24 hours — at a push 36 hours — before Washington announced that it would ‘tone down’ its involvement and agitate for NATO to take over. Perhaps keen to satisfy the needs of the 24-hour rolling news agenda, America has just overseen the world’s first-ever outburst of 24-hour imperialism.
