It's not just me - Part 2

Hoppy beer is awful—or at least, its bitterness is ruining craft beer’s reputation. - Slate Magazine

The boutique beer business is big in the US as well as Australia, and I am happy to hear that I am not the only person who is finding too many of these beers just too overpoweringly hoppy.

While different hops are supposed to have different taste characteristics (other than simple "bitter"), it's good to read that there really is no point in making it too bitter:

From a consumer’s standpoint, though, beers overloaded with hops are a pointless gimmick. That’s because we can’t even taste hops’ nuances above a certain point. Hoppiness is measured in IBUs (International Bitterness Units), which indicate the concentration of isomerized alpha acid—the compound that makes hops taste bitter. Most beer judges agree that even with an experienced palate, most human beings can’t detect any differences above 60 IBUs. Sierra Nevada Pale Ale, one of the hoppiest beers of its time, clocks in at 37 IBUs. Some of today's India pale ales, like Lagunitas’ Hop Stoopid, measure around 100 IBUs. Russian River’s Pliny the Younger, one of the most sought-after beers in the world, has three times as many hops as the brewery’s standard IPA; the hops are added on eight separate occasions during the brewing process.

Craft brewers’ obsession with hops has overshadowed so many other wonderful aspects of beer. So here’s my plea to my fellow craft beer enthusiasts: Give it a rest.

“Star Trek Into Darkness”: Who made J.J. Abrams the sci-fi god? - Salon.com

Readers will know I don't care for the directorial work of JJ Abrams, so it's good to read a review by a critic who seems pretty lukewarm on him too.   (He's enjoyed him more than me, though. I think.)

I'm also lukewarm on the new version of Star Trek, and was bored with Abram's first effort. 

This new movie has good reviews, but after reading Andrew O'Hehir's, I don't think I'll bother seeing it.

O'Hehir's review is pretty witty, if you ask me.  It ends on this note, for example:

There’s absolutely nothing wrong with “Star Trek Into Darkness” – once you understand it as a generic comic-book-style summer flick faintly inspired by some half-forgotten boomer culture thing. (Here’s something to appreciate about Abrams: This is a classic PG-13 picture, with little or no sex or swearing, but one that never condescends.) That’s the way almost everyone will experience it, and fair enough. Still, if you feel like bitching about it, come on over. We’ll crack a couple of watery brews and complain (in Klingon) about Uhura’s ill-fitting romance with Spock, or Chris Pine’s frat-boy weightlifter Kirk, who completely lacks the air of provincial, semi-educated suavity that made William Shatner the greatest bad actor in TV history. Or the fact that those in charge of the “Star Trek” universe could have entrusted its rebirth to someone who actually liked it.

Unwise tax cuts, unwise spending cuts

BUDGET 2013: Who framed the budget bloopers? | Business Spectator

Here's a good summary of the Australia Institute work which pins current budget deficits on tax cuts which Costello invented and Labor implemented:
 

In a pre-budget briefing paper, Australia Institute senior economist Matt Grudnoff said: “The impact of the Howard/Costello income tax cuts on the federal budget has been huge. They were delivered at a time of strong economic growth, ignoring what would happen when that growth slowed.

“Costello chose to take the windfall generated by the mining boom to fund large and permanent cuts to income tax. What he didn’t say at the time was that he was funding a structural change to the budget with a cyclical boom. This was simply unsustainable.”

This is not a new story. However, Grudnoff has used the same economic modelling tool used by many government forecasters, NATSEM, to work out how many more billions would have flowed into government coffers had Swan and Rudd just said ‘No’ to the Costello cutting program.

Grudnoff found that not only would the budget likely be into the black by now, but that the cuts disproportionately benefited higher socio-economic groups. He found that “income tax cuts between 2005-06 and 2011-12 have taken a massive $169 billion out of the federal budget, meaning the deficit announced by Prime Minister Gillard might not have eventuated”.

He adds: “Had the tax cuts not taken place, the 2011-12 budget would have been $38 billion better off. Instead, the top 10 per cent of income earners gained $16 billion. This was more than the total benefit to the bottom 80 per cent of income earners.”

You might have expected, therefore, that a Labor government would have done its sums, worked out that the cuts didn’t further the cause of ‘fairness’, and stopped the madness of rolling tax cuts that were funded by an unexpected mining-revenue windfall at the start, and during the GFC, funded by issuing billions of dollars worth of government bonds.
But they didn’t.

Sounds pretty convincing, but the political problem for Labor is that it is hard for them to admit that they made a bad call by promising to deliver the Costello tax cuts.  

What I can do, on the other hand, is ridicule those who argue that lower taxes always works for the good. 

And back to the matter of the effect of further cutting as promised by a future Abbott government:

But Swan bashing aside, there is a more sinister aspect to the chart above, given that it’s likely to be Treasurer Hockey giving next year’s budget speech.

Think for a minute what would have happened to the economy, and tax receipts, if Rudd and Swan had tried to balance the budget not by ending the Costello tax-cut program, but by cutting spending.

Had they been cutting spending to the bone from 2008 to the present, the mistakes of the European austerity programs would have been repeated here, albeit in milder form. That is, by cutting into a downturn, many more businesses would have collapsed, GDP growth would have slowed or gone backwards, and tax receipts would have plunged lower still.

But that is exactly what Tony Abbott and Joe Hockey have planned for next year. Their hope is that business, buoyed by the scrapping of the carbon and mining taxes, red tape reductions and less regulation, will create a new surge of economic activity that will start to refill the coffers.

It’s not impossible, and we’re certainly not in Europe’s dire predicament. But it does seem like a gamble as big as some of the punts Swan and Rudd took during the GFC and which, thankfully, mostly worked out.

The federal budget may be $19.4 billion in the red for 2012/13, but the economy is still growing, unemployment, inflation and interest rates are low. That may be a scenario we look back on with some nostalgia if the Abbott/Hockey punt doesn’t work out.

About that reduced revenue

From the 22 minute mark, I think there is a very decent discussion about Treasury's way optimistic (and wrong) budget forecast for revenue for this year.  (Down $17 million or so, which is very close to the year's budget deficit of $19 million.)



Andrew Leigh does the talking for Labor.  He always impresses as a smart and decent politician economist.   What's peculiar is that, even though the way Sinclair Davidson spins Labor's economic management must drive Leigh berserk, Davidson does always speak up for Leigh as being a "good guy".   Odd.

Tony Abbott: a weak leader with poor judgement

So, Tony Abbott is now vacillating on support for the "recognition of local government" referendum to be held at the next election:

On Monday, Mr Abbott said that while he supported the idea of allowing the federal government to directly fund local councils, he thought the government was rushing the referendum at the last minute. Mr Abbott added that the government should not be ''muddying the waters'' of the election with another vote.

''(The election) ought to be a referendum on Julia Gillard and the carbon tax rather than a referendum on local government,'' he said.

Why doesn't he just say "I'm more interesting in playing politics than seeing something useful gets done"?

His wavering comes after strong complaint from the old guard that he shouldn't support it:

This week former Liberal heavyweights Nick Minchin and Peter Reith spoke out against the idea. It is up to the Federal Government to propose the referendum but in-principle support from the Coalition makes it more likely that will happen.

and the "new guard" of dimwits as led by Andrew Bolt,  and his best friends forever in the IPA, and shared by such shining luminaries as Cory Bernardi. 

Sure, this issue has been raised before by Labor and failed, but this time there is solid, practical, court decision based reasons as to why the constitutional amendment is warranted.

Some in the Coalition (Barnaby Joyce, of all people!) recognize this, but more are interested in re-hashing the idea of it being about ideology and Labor power grabs. 

The IPA and their friends in the large, stupid, ideologically driven climate change skeptic faction of the Coalition (which, apart from Joyce, seem to compromise the bulk of the opposition to the referendum) should explain to me - in the current budgetary and economic conditions, what Labor Federal government is going to be interested in directly funding a huge amount of local government responsibilities just so they say "ha ha, we're in control"?

But back to Tony:  his new, barbed wire fence straddling attitude on this is just like his "it depends who I'm talking to"  approach to climate change.   His vacillation on an ETS, and final decision to take an opportunistic stand against it at the beck and call of Right wing talk back radio and Andrew Bolt is how he got the leadership.

The only policy which he has ever owned totally is one which virtually no one, except a hand full of feminist commentators, thinks makes economic sense (his overly generous parental leave plan.)

In short, the policies on which he chooses to dig his heals in are weak and ill founded; on those things which are practical and worthy he's still sniffing the wind as to what he should do.    (Another vacillation - the NBN lite plan.)

He is a crook leader who does not deserve to win government. 

Speaking of Parkinson's

Brain damage 'crisis' looms from illicit drug use - ABC News (Australian Broadcasting Corporation)

Researchers in Adelaide are investigating links between stimulant use and an increased risk of people developing Parkinson's disease.

They said many drug users were developing a brain abnormality which also was seen in people afflicted with Parkinson's.

"People who have used illegal stimulants in the past have a change in a brain region that's right in the middle of their brain called the susbtantia nigra," explained Dr Gabrielle Todd, a senior researcher at the University of South Australia.

A recent German study found otherwise-healthy people with that abnormality were 17 times more likely than others to develop Parkinson's.

"When we looked at the brain stems of fairly young people, all less than 45 years old, they had the same changes that we saw in people with Parkinson's disease," Flinders Medical Centre neurologist Dr Rob Wilcox said.

The free market of (rodent) death

Of mice and markets | Ars Technica

This study which was reported last week was not well reported in some places, but I think this explanation at the link does it pretty well.  The opening paragraphs:

How do ethics and the free market interact? As the authors of a new paper on the topic point out, the answer is often complicated. In the past, Western economies had vigorous markets for things we now consider entirely unethical, like slaves and Papal forgiveness for sins. Ending those practices took long and bloody struggles. But was this because the market simply reflects the ethics of the day, or does engaging in a market alter people's perception of what's ethical?

To find out, the authors of the paper set up a market for an item that is ethically controversial: the lives of lab animals. They found that, for most people, keeping a mouse alive, even at someone else's cost, is only worth a limited amount of money. But that amount goes down dramatically once market-based buying and selling is involved.

 The article then goes into detail as to how the experiment worked.  It's pretty fascinating.

Fortunately, while the study could be used by to attack markets and capitalism, the authors do recognize something important:

....they're well aware that other forms of resource distribution have fostered some fantastically unethical behavior. Or, as they put it in more academic terms, "Other organizational forms of allocation and price determination such as in totalitarian systems or command societies do not generically place higher value on moral outcomes."

Still, it probably does have something useful to think about in terms of markets and ethics.

My second tech post in a day.

This one is a pretty interesting, and amusing, description of how Google Glass currently works, and why they are (at least not yet) the best device for secretly recording video or taking photos.

Still, if they become cheap and popular in future, I would not be surprised if we start seeing a lot more video of street crime than before.  After all, despite what the article says, their use will still be less conspicuous (and easier) than holding up your mobile phone to record video.

Adventures in rooting (a consumer warning)

It was about 9 months ago that I bought a Samsung Tablet, the Galaxy Tab 2 10.1, which is still commonly on sale and now down to just under $300.   It's pretty much at the bottom of the Samsung line, and the reviews even when it came out indicated not to expect top performance.  However, for your basic tablet user, I've been pretty happy with it, and Google Play services (with the recent opening of their music store in Australia) have improved a lot.

But a few days ago it started acting strangely.   Trying to type into any app (such as a browser) would immediately cause the app to stop working.  Also, I had created a half dozen folders on the home page in which to sort out my apps into categories, and I could not open any of those folders.  (The warning on that was "SecLauncher has stopped working.")

Googling around on my PC (because I could not search anything via the tablet) about the typing problem (but not the folder problem) quickly showed from Android forums that this was a known issue that sometimes occurred in this model tablet, and that it has been occurring for quite some time (more than 12 months, I think.)   Someone complained that they had contacted Samsung and a vague promise that they would fix it in future was made.

However, I don't think there has ever been an update for my Tablet's Android version since I bought it.  (Even though it appears an update has started to be rolled out elsewhere around the globe in about December 2012.  Australia must be low on their priority.)

So - the problem I had was with the Samsung clipboard, and could only be fixed by either doing a factory reset (which would not guarantee that the problem would not return) or "root" the Tablet via some software and slightly tricky instructions which could, if it all went horribly wrong, "brick" the Tablet and make it good for nothing, and then delete the data/clipboard folder contents.

I went for the latter option, and followed a couple of sets of instructions (first here, but then to XDA forum) because it seems it is hard to find one perfectly clear set of instructions for something like this. 

Anyhow, I finally got there, after a few hours of research and fiddling and not understanding exactly what was going on.

Anyone reading who has struck problems doing this - I might be able to help with a few tips of what was not working for me.

So, next problem: having successfully "rooted" my tablet,  I couldn't find the data/clipboard at all.

I tried the "File manager" that came with Samsung, and an app manager I had downloaded which had an option to allow access to root files which had to be turned on, but I still could not find the relevant folder.

I knew there were other file manager apps to download, but here's the thing:  I still couldn't type into Google Play to find them.   I had to search through categories, but they seem to list the "top paid" or "top free", and if want you want isn't in the top, you can't get to it.  Furthermore, if it was a paid app that I wanted to download (and there was one or two possibilities) I could not type in my password to confirm payment!

Still, if you find one app that's kinda relevant, you can see links to other possible ones of interest, and that is how I stumbled across File Explorer (which is free) and a separate, now free, File Explorer (Root Add on) which allows root access via File Explorer.

Using these apps, I did find the data/clipboard folder, deleted its contents, and yes indeed, the Tablet started working normally again.

Presumably, if it happens again, I have all the tools to fix it.

But here's the thing:   I must never put File Explorer in a folder, because that may make it hard to get to if the problem re-develops.

Apparently, having a "rooted" Tablet means you can fiddle with it and do all sorts of things - perhaps such as uploading the new Jellybean Android instead of waiting for Samsung to deem Australia worthy enough to receive it.

I'm not sure what I'll do.  The warranty is gone anyway.

But the final lesson is:   this is pretty poor service by Samsung, not fixing a serious problem like this and just telling people they have to reset the Tablet to factory (and re-load all apps and data back to it.)

Shame, Samsung, shame.

More on fizzy drinks

A soda a day keeps the doctor in pay: soft drinks and diabetes

A can a day of sugary oft drink is a bad idea:

This large study from Europe found drinking a 12 ounce (about 355 ml) can of soft drink, or soda, a day was associated with a 20% increase in the risk of developing diabetes. This same effect has previously been observed in populations from the United States, Finland and Singapore.

If this is a real effect, as increasingly looks to be the case, it has massive implications. Half of eight-year-olds in the United States already drink this amount of soda, and teenage males consume more than double that. In conjunction with soft drink consumption among American adults, this represents tens of millions at risk of diabetes in the United States alone. Hundreds of millions more people are affected in other developed and developing countries worldwide.

There’s an obvious reason why soft drink consumption causes diabetes – more sweetened drinks equal more calories, which equals weight gain. Excess weight is the single most important factor in the global diabetes epidemic. While soft drinks may have effects on diabetes independent of obesity, this latest study (again) implicates weight gain as a key factor.

I am a little relieved to read the next bit, though:

The study’s apparently anomalous finding of an association between diet sodas and diabetes likely reflects “reverse causation” – a phenomenon whereby people switch to diet soft drinks once they start to get the health problems caused by regular ones. So it’s the development of disease that’s causing people to drink diet soft drinks, not the diet soft drinks causing disease.

My Pepsi Max remains safe, perhaps.

More in Søren than in manga

Julian Baggini — I still love Kierkegaard

I quite enjoyed this summary of the somewhat odd philosophy of Kierkegaard from someone who first became a fan as a teenager.

This paragraph amused me:

Yet alongside this melancholy was a mischievous, satirical wit. Kierkegaard was a scathing critic of the Denmark of his time, and he paid the price when in 1846 The Corsair, a satirical paper, launched a series of character attacks on him, ridiculing his gait (he had a badly curved spine) and his rasping voice. Kierkegaard achieved the necessary condition of any great romantic intellectual figure, which is rejection by his own time and society. His biographer, Walter Lowrie, goes so far as to suggest that he was single-handedly responsible for the decline of Søren as a popular first name. Such was the ridicule cast upon him that Danish parents would tell their children ‘don’t be a Søren’. Today, Sorensen — son of Søren — is still the eighth most common surname in Denmark, while as a first name Søren itself doesn’t even make the top 50. It is as though Britain were full of Johnsons but no Johns.

As for the title of this post:  I was trying to make a pun, and took a stab that there would be manga versions of some of Kirkegaard's books.  Looks like I was right!

Bacterial ecology, continued

To Beat Bad Breath, Keep the Bacteria in Your Mouth Happy: Scientific American

There seems to be a lot of interest suddenly in scientific circles about how bacterial ecology (particularly in the gut) affects the general health of  humans.  Here's another instalment of the story, but this time starting at the mouth:

Bacterial geneticists contributing to the Human Microbiome Project, funded by the National Institutes of Health, have so far identified about 1,000 species of bacteria that commonly inhabit human mouths. Yet one person's particular mix of “bacterial colleagues,” as Rosenberg calls them, is probably quite different from another's. “Each person has maybe 100 to 200 of those bacterial species colonizing their mouth at any given time,” says Wenyuan Shi, a microbiologist at the University of California, Los Angeles.

During birth our previously sterile mouth picks up some of our mother's bacteria, and in childhood we quickly acquire new microbial colonizers. Studies suggest that a preschooler's population of mouth microbes most closely mimics his or her primary caregiver's. As the years go on, diet, stress, illness, antibiotics and other forces can shift the demographics of an individual's microbial community—and change its collective aroma. When bacteria that release smelly compounds dominate, chronic bad breath may be one of the consequences.

Many current treatments do not improve oral ecology—in fact, they might make matters worse. Although some mouthwashes merely mask unpleasant odors, alcohol-based rinses sold in drugstores and prescription rinses containing chlorhexidine or other antiseptics target all oral bacteria, stinky and otherwise. Shi says that approach has several drawbacks. A chlorhexidine rinse, for example, may improve breath for as long as 24 hours but can temporarily change the taste of food. In one study, 25 percent of subjects experienced a tingling or burning sensation on the tongue after a week of use. Heavy use of rinses with alcohol can dry out the mouth, sometimes exacerbating bad breath. Further, wiping out too many of the mouth's native bacteria could disrupt the usual checks and balances, making way for opportunistic species responsible for gum disease and other infections to move in and take over.

 The article goes on to discuss new treatments being tested to give a more permanent "cure" by changing the bacterial mix in the mouth.  For example:

Other teams are investigating whether probiotics rife with a gram-positive bacterial strain known as Streptococcus salivarius K12 can fight halitosis. A common resident of the mouth and respiratory tract, S. salivarius K12 is benign and known to produce substances that deter harmful bacteria. In a recent study by researchers in New Zealand and Australia, volunteers gargled with a chlorhexidine mouthwash to clear their palate of many native bacteria and subsequently sucked on lozenges laced with K12. Seven and 14 days later they had much sweeter breath. Presumably K12 outcompeted its foul-smelling kin, opening up niches for less offensive species.

 I wonder if protracted kissing with someone with good breath can help too!

Keynes and the long term

Yesterday, when the story about Niall Ferguson quipping that Keynes didn't worry about the future because he was gay and childless was doing the rounds, I commented elsewhere that having children certainly seems to have no effect at all on the Tea Party Right and their dismissive attitude to the long term  issue of climate change.   (The point being that they are an obvious example of how having kids is not co-related to "concern with the future of humanity".)

But what I suspected was that Ferguson's take on Keynes not being concerned about the future was the more fundamentally wrongheaded claim.  Not being one who reads much about economics, though, I didn't know where to find a good commentary on this aspect.

Overnight, what I wanted appeared at Slate.  It's a good read.  Here is the opening slab, for which I trust Slate will forgive me for reproducing:

Niall Ferguson, the distinguished historian who for the past several years has increasingly abandoned his trade in favor of inept conservative punditry, stepped in it over the weekend when he told an investors’ conference that John Maynard Keynes’ allegedly misguided ideas stemmed from the fact that he was gay and had no intention of having children, and was thus blinded to the importance of long-run considerations.

When an uproar ensued, Ferguson, to his credit, offered a full and complete apology on his website. But both the controversy and the apology primarily reflect the welcome fact that gay-bashing is increasingly frowned upon in polite society. They don’t confront the larger smear, which is against Keynes’ ideas. The fact of the matter is that both Keynes personally and “Keynesian” thinkers about macroeconomics in general care deeply about long-term issues. In fact, Keynes is one of the deepest thinkers about the long-term economic trajectory of all time.

The assumption that Keynes only cared about the short run stems from Keynes’ too-often quoted line that “in the long-term we are all dead.” This is, obviously, true. But while it’s often taken to be something like a 1930s version of YOLO, that kind of carpe diem economics has nothing to do with what Keynes was actually writing about.

The line appears not in the General Theory of Employment, Interest, and Money but in 1923’s Tract on Monetary Reform. Most countries, including Great Britain, had abandoned the gold standard during World War I. After the war, the major powers sought to return to gold and the British authorities wanted to return their currency to its pre-war peg, a step Keynes thought would be disastrous. The question of the long run arose in response to the claim that overvaluing a currency relative to the currencies of its trade partners can’t make a difference since in the long-run domestic prices will adjust to any exchange rate.

Keynes says that this is true. If after the conclusion of the American Civil War “the American dollar had been stabilized and defined by law at 10 percent below its present value” that would have had no implications for the world economy of the 1920s, 60 years later. Nominal prices would have adjusted. “But this long run is a misleading guide to current affairs,” he wrote, “In the long run we are all dead. Economists set themselves too easy, too useless a task if in tempestuous seasons they can only tell us that when the storm is long past the ocean is flat again.”

Read the whole thing.

It certainly helps illustrate the intellectual poverty of what passes for much Right wing commentary on economics in the last few years.

Fan boys and girls who are not to be trusted

Diana Rigg in Doctor Who: The Crimson Horror recap.

I continue to be amazed at the global fan boy detailed analysis, excitement and praise appearing at Slate (above) and The Guardian after every episode of Dr Who, when I am finding the stories increasingly incredibly stupid.

Last night's episode, for example, in my opinion, just made no sense as a story whatsoever.  I personally think that the makers of the show think they can include any steampunk element and fan boys will "ooh" and "ahh".  (Last night, it was a steampunk ballistic missile type thingee.)  

The stories have become absolutely hopeless.   The end times must be near, one would think...
