One of those terrible events that I remember as if they happened yesterday.
The aftermath, the investigation led by Richard P. Feynman up to the final report that pinned it down on a single O-Ring failing fatally was what got me hooked on sci.space (on Usenet - anyone remember what that used to be?), and "the internet" which in 1986 was still in its infancy over here.
 
Thirty years ago today, 74.130 seconds after liftoff, the Challenger fell. 

I want to write a long story about this – to tell the story of the people aboard and the people on the ground, of the crew and of the people who studied what happened, of the things that we learned and changed, of all the things we should remember about that day. But thirty years later, it still hurts too much for me to write it.

I can still see the two SRB's spinning out of control after the airframe disassembled, forming two horns coming out of an oddly round cloud, if I close my eyes. I can still remember the utter confusion and disbelief that followed, as nobody could even tell, at first, if they had actually seen what they thought they saw. I remember being so upset, that night, not being able to fully wrap my heart around it. And nightmares still sometimes wake me, of rockets falling out of a perfectly blue sky.

To the seven who gave their lives that day – CDR Francis R. Scobee, pilot Michael J. Smith, mission specialists Ellison S. Onizuka, Judith A. Resnik, and Ronald E. McNair, and payload specialists Gregory B. Jarvis and S. Christa McAuliffe – you are not forgotten.

I was in the building just to the north of the Sears Tower the moment STS-51-L failed.  A Brit on the team came charging into the coding bullpen, breathlessly saying "The Challenger exploded!"

I responded, "Damn.   Good thing the Hubble Space Telescope wasn't aboard."

Everyone thought I was a cruel bastard.

TL;DR: it doesn't take an oppressive government or an international banking industry conspiracy to ruin alternate finance systems, when personal pettiness and unwillingness to find consensus on (or even discuss) necessary changes achieve the very same effect, only quicker and just as effective.
 
"But despite knowing that Bitcoin could fail all along, the now inescapable conclusion that it has failed still saddens me greatly. The fundamentals are broken and whatever happens to the price in the short term, the long term trend should probably be downwards. I will no longer be taking part in Bitcoin development and have sold all my coins."

Who needs QA anyway?
Let's test in Prod!

Es "fehlte" ja nicht nur "das S" beim letzten Update. Deutsche und englische Ansagen wurden wild gemischt, in Rohr wurde grundsätzlich die falsche Seite zum Aussteigen angesagt, etc.
Dass es nun beim nächsten Update nur noch peinlicher wird, hat da schon eine gewisse Logik.

Let's not fool ourselves and believe for a single second that such policies are limited to the US of A. It works just the very same (on some of the better days with a dollop less of doing it shamelessly in the open) over here.
 
"The very richest are able to quietly shape tax policy that will allow them to shield billions in income."

How is this possible? How can $Billionaires help shape tax policy which is determined by Congress? Who in Congress are the accomplices of these $Billionaire tax-cheats?

The republicans.

There are two fundamental dynamics in American politics today. First Extremely Wealthy Americans pay the republican party to lower their taxes:

"In the heat of the presidential race, the influence of wealthy donors is being tested. At stake is the Obama administration’s 2013 tax increase on high earners — the first in two decades — which amounted to a significant increase for the ultrawealthy. Also at stake is an I.R.S. initiative to ensure that, in effect, the higher rate sticks by cracking down on tax avoidance by the wealthy.

While Democrats like Bernie Sanders and Hillary Clinton have pledged to raise taxes on these voters, virtually every Republican has advanced policies that would vastly reduce their tax bills, sometimes to as little as 10 percent of their income."

How do these republican-supporting #TaxCheats  avoid paying taxes?

"Moreover, each has exploited an esoteric tax loophole that saved them millions in taxes. The trick? Route the money to Bermuda and back. [...]

Operating largely out of public view — in tax court, through arcane legislative provisions and in private negotiations with the Internal Revenue Service — the wealthy have used their influence to steadily whittle away at the government’s ability to tax them. The effect has been to create a kind of private tax system, catering to only several thousand Americans.

The impact on their own fortunes has been stark. Two decades ago, when Bill Clinton was elected president, the 400 highest-earning taxpayers in America paid nearly 27 percent of their income in federal taxes, according to I.R.S. data. By 2012, when President Obama was re-elected, that figure had fallen to less than 17 percent, which is just slightly more than the typical family making $100,000 annually, when payroll taxes are included for both groups."

The second major dynamic in American politics is that the republican party panders to ethnocentric white lower-income and middle class voters justifying the tax cuts to the Extremely Wealthy by using thinly-veiled #Racism . But that is a story for another day.

“There’s this notion that the wealthy use their money to buy politicians; more accurately, it’s that they can buy policy, and specifically, tax policy,” said Jared Bernstein, a senior fellow at the left-leaning Center on Budget and Policy Priorities who served as chief economic adviser to Vice President Joseph R. Biden Jr. “That’s why these egregious loopholes exist, and why it’s so hard to close them.”

Yes and this notion is correct. To be diplomatic, Professor Bernstein stated that the Extremely Wealthy can buy politicians to create egregious tax loopholes. What he meant to say is that the Extremely Wealthy are buying republican politicians. How do we know? Because the republicans want to eliminate all or most taxes on the wealthy such as the #Inheritance  tax (which kicks in only after $5 million):

"At the same time, most Republican candidates favor eliminating the inheritance tax, a move that would allow the new rich, and the old, to bequeath their fortunes intact, solidifying the wealth gap far into the future. And several have proposed a substantial reduction — or even elimination — in the already deeply discounted tax rates on investment gains, a foundation of the most lucrative tax strategies."

As you can see from the accompanying graph, "Two decades ago, when Bill Clinton was elected president, the 400 highest-earning taxpayers in America paid nearly 27 percent of their income in federal taxes, according to I.R.S. data. By 2012, when President Obama was re-elected, that figure had fallen to less than 17 percent, which is just slightly more than the typical family making $100,000 annually, when payroll taxes are included for both groups."

Lots of middle-class people including myself (PPKFP) paid more than 17% in taxes last year. Unfortunately we could not buy off republican politicians so that we can run tax scams like the following (which actually are quite clever I must say):

"Mr. Loeb, for example, has invested in a Bermuda-based reinsurer — an insurer to insurance companies — that turns around and invests the money in his hedge fund. That maneuver transforms his profits from short-term bets in the market, which the government taxes at roughly 40 percent, into long-term profits, known as capital gains, which are taxed at roughly half that rate. It has had the added advantage of letting Mr. Loeb defer taxes on this income indefinitely, allowing his wealth to compound and grow more quickly."

My (remember I am speaking only for myself PPKFP and not for the far more ethical Professor Krugman), selfish and corrupt side wishes I could do this kind of scam to avoid the capital gains tax indefinitely like Mr. Loeb.

What has President Obama done to fight this republican corruption?

"President Obama has made fighting tax evasion by the rich a priority. In 2010, he signed legislation making it easier to identify Americans who squirreled away assets in Swiss bank accounts and Cayman Islands shelters.

His I.R.S. convened a Global High Wealth Industry Group, known colloquially as “the wealth squad,” to scrutinize the returns of Americans with incomes of at least $10 million a year.

But while these measures have helped the government retrieve billions, the agency’s efforts have flagged in the face of scandal, political pressure and budget cuts. Between 2010, the year before Republicans took control of the House of Representatives, and 2014, the I.R.S. budget dropped by almost $2 billion in real terms, or nearly 15 percent. That has forced it to shed about 5,000 high-level enforcement positions out of about 23,000, according to the agency."

In summary, President Obama has lost this battle to the republicans:

'For the ultra-wealthy, “our tax code is like a leaky barrel,” said J. Todd Metcalf, the Democrats’ chief tax counsel on the Senate Finance Committee. ”Unless you plug every hole or get a new barrel, it’s going to leak out.”
The very richest are able to quietly shape tax policy that will allow them to shield billions in income.

Well - the way the US political system works with donation-based election campaigns you can guess that this is just a thinly veiled attempt at covering the fact that you really can just go and outright buy poiticians

Always happy to help :-)
The interesting question is, how they intend to measure the "how far this picture can get out in the world".

Let's hope that this weather forecast for next Thursday is slightly pessimistic ...

On the plus side (sic!): no windchill.

2 mm left and right of it is was more like +5, and the numbers in the top row give a more average picture of what (the absence of) winter is like these days, so I suspect only a small glitch in the matrix, but one worth a screenshot anyway :-)

Every year between Christmas and New Year when it's Congress Time,  we are reminded in a lot of detail how utterly broken most (well, everything) of our security infrastructure is, and that we are ruled by a bunch of anti-intellectual power-hungry greedy morons.

And every year there is a small beacon of light and hope.

I'm far from having caught up with all the #32c3 recordings, but I thoroughly enjoyed this presentation by Matthew Borgatti, Lead Scientist at Super-Releaser, a robotics company that specializes in soft robots.

The title of the presentation is clickbait of the good kind, because it lures you into a world of expected and unexpected application areas for pneumatically controlled 3D-printed squishy gadgets, from space suit gloves that don't make your fingernails fall off to assistance systems for patients with cerebral palsy and intelligent artificial limbs that distribute shock absorption to where it can be tolerated best.

They look at nature for new ways of modeling things, from squid beaks to housefly legs.

And they strongly believe in open sourcing their ideas.

Rather unusually, there is more than half an hour of Q&A that very nicely complements the presentation.

Strongly recommended.
