Some news are still worth to remember even when it goes old.

Too much information

Applying the concept of a sprint in Agile development can help me cope with information overload. I block off a period of time, 2-3 hours, to concentration on my work. I will hide myself, disconnect from email and instant messages to avoid any interruption. I also learn that nothing cannot wait for a few hours or a day or two. You just have to set the expectation right that people cannot demand instance response from you all the time.

How to cope with data overload

GOOGLE “information overload” and you are immediately overloaded with information: more than 7m hits in 0.05 seconds. Some of this information is interesting: for example, that the phrase “information overload” was popularised by Alvin Toffler in 1970. Some of it is mere noise: obscure companies promoting their services and even more obscure bloggers sounding off. The overall impression is at once overwhelming and confusing.

“Information overload” is one of the biggest irritations in modern life. There are e-mails to answer, virtual friends to pester, YouTube videos to watch and, back in the physical world, meetings to attend, papers to shuffle and spouses to appease. A survey by Reuters once found that two-thirds of managers believe that the data deluge has made their jobs less satisfying or hurt their personal relationships. One-third think that it has damaged their health. Another survey suggests that most managers think most of the information they receive is useless.

Commentators have coined a profusion of phrases to describe the anxiety and anomie caused by too much information: “data asphyxiation” (William van Winkle), “data smog” (David Shenk), “information fatigue syndrome” (David Lewis), “cognitive overload” (Eric Schmidt) and “time famine” (Leslie Perlow). Johann Hari, a British journalist, notes that there is a good reason why “wired” means both “connected to the internet” and “high, frantic, unable to concentrate”.

These worries are exaggerated. Stick-in-the-muds have always complained about new technologies: the Victorians fussed that the telegraph meant that “the businessman of the present day must be continually on the jump.” And businesspeople have always had to deal with constant pressure and interruptions—hence the word “business”. In his classic study of managerial work in 1973 Henry Mintzberg compared managers to jugglers: they keep 50 balls in the air and periodically check on each one before sending it aloft once more.

Yet clearly there is a problem. It is not merely the dizzying increase in the volume of information (the amount of data being stored doubles every 18 months). It is also the combination of omnipresence and fragmentation. Many professionals are welded to their smartphones. They are also constantly bombarded with unrelated bits and pieces—a poke from a friend one moment, the latest Greek financial tragedy the next.

The data fog is thickening at a time when companies are trying to squeeze ever more out of their workers. A survey in America by Spherion Staffing discovered that 53% of workers had been compelled to take on extra tasks since the recession started. This dismal trend may well continue—many companies remain reluctant to hire new people even as business picks up. So there will be little respite from the dense data smog, which some researchers fear may be poisonous.

They raise three big worries. First, information overload can make people feel anxious and powerless: scientists have discovered that multitaskers produce more stress hormones. Second, overload can reduce creativity. Teresa Amabile of Harvard Business School has spent more than a decade studying the work habits of more than 9,000 people. She finds that focus and creativity are connected. People are more likely to be creative if they are allowed to focus on something for some time without interruptions. If constantly interrupted or forced to attend meetings, they are less likely to be creative. Third, overload can also make workers less productive. David Meyer, of the University of Michigan, has shown that people who complete certain tasks in parallel take much longer and make many more errors than people who complete the same tasks in sequence.

What can be done about information overload? One answer is technological: rely on the people who created the fog to invent filters that will clean it up. Xerox promises to restore “information sanity” by developing better filtering and managing devices. Google is trying to improve its online searches by taking into account more personal information. (Some people fret that this will breach their privacy, but it will probably deliver quicker, more accurate searches.) A popular computer program called “Freedom” disconnects you from the web at preset times.

A second answer involves willpower. Ration your intake. Turn off your mobile phone and internet from time to time.

But such ruses are not enough. Smarter filters cannot stop people from obsessively checking their BlackBerrys. Some do so because it makes them feel important; others because they may be addicted to the “dopamine squirt” they get from receiving messages, as Edward Hallowell and John Ratey, two academics, have argued. And self-discipline can be counter-productive if your company doesn’t embrace it. Some bosses get shirty if their underlings are unreachable even for a few minutes.

Most companies are better at giving employees access to the information superhighway than at teaching them how to drive. This is starting to change. Management consultants have spotted an opportunity. Derek Dean and Caroline Webb of McKinsey urge businesses to embrace three principles to deal with data overload: find time to focus, filter out noise and forget about work when you can. Business leaders are chipping in. David Novak of Yum! Brands urges people to ask themselves whether what they are doing is constructive or a mere “activity”. John Doerr, a venture capitalist, urges people to focus on a narrow range of objectives and filter out everything else. Cristobal Conde of SunGard, an IT firm, preserves “thinking time” in his schedule when he cannot be disturbed. This might sound like common sense. But common sense is rare amid the cacophony of corporate life.

Slaying the Cable Monster: Why HDMI Brands Don’t Matter

I have been keep saying those who buy expensive HDMI cable are idiots and now here is the prove.

By Will Greenwald, May 13 2011, PC Magazine
For the vast majority of HDTV owners, a $5 HDMI cable will provide the same performance as a $100 one.

You’ve probably experienced this when shopping for a new HDTV: A store clerk sidles up and offers to help. He then points you toward the necessary HDMI cables to go with your new television. And they’re expensive. Maybe $60 or $70, sometimes even more than $100 (You could buy a cheap Blu-ray player or a handful of Blu-ray discs for that price!). The clerk then claims that these are special cables. Superior cables. Cables you absolutely need if you want the best possible home theater experience. And the claims are, for the vast majority of home theater users, utter rubbish.

The truth is, for most HDTV setups, there is absolutely no effective difference between a no-name $3 HDMI cable you can order from Amazon.com and a $120 Monster cable you buy at a brick-and-mortar electronics store. We ran five different HDMI cables, ranging in price from less than $5 up to more than $100, through rigorous tests to determine whether there’s any difference in a dirt-cheap cable and one that costs a fortune.

HDMI Basics

The first thing to remember about HDMI is that it is a digital standard. Unlike component video, composite video, S-video, or coaxial cable, HDMI signals don’t gradually degrade, or get fuzzy and lose clarity as the signal fades or interference grows. For digital signals like HDMI, as long as there is enough data for the receiver to put together a picture, it will form. If there isn’t, it will just drop off. While processing artifacts can occur and gaps in the signal can cause blocky effects or screen blanking, generally an HDMI signal will display whenever the signal successfully reaches the receiver. Claims that more expensive cables put forth greater video or audio fidelity are nonsense; it’s like saying you can get better-looking YouTube videos on your laptop by buying more expensive Ethernet cables. From a technical standpoint, it simply doesn’t make sense.

This doesn’t mean that all HDMI cables are created equal in all cases. HDMI includes multiple specifications detailing standards of bandwidth and the capabilities of the cable.

The current HDMI specification, version 1.4a, requires all compliant cables to support 3D video, 4K resolution (approximately 4000-by-2000-pixel resolution, or about four times the detail of the current HD standard of 1080p), Ethernet data transmissions, and audio return channels. Each of these features requires more bandwidth, and considerably older HDMI cables (and all older HDMI-equipped devices) rated at HDMI 1.3b or lower can’t handle that much bandwidth. For most users, 3D is the only feature they’ll use. Ethernet over HDMI is used mostly for networking devices instead ofconnecting viapure Ethernet or Wi-Fi (the methods most consumer electronics products use). Audio return channels are only useful in certain situations with dedicated sound systems (and the same task can be accomplished by running an audio cable to the system). And there aren’t currently any consumer-grade displays or playback devices capable of handling 4Kresolutions (the least-expensive 4K projector you’ll find is more than $75,000). In all of these cases, it’s a yes or no question: does it support these features? There is no question of clarity or superior signal.

That said, there are cases where higher quality cables and going to lengths to maintain signal quality are important. They just aren’t cases that apply for most HDTV owners. If you’re going to run an HDMI cable for lengths longer than 10 feet, you should be concerned about insulation to protect against signal degradation. It’s not an issue for 6-foot lengths of cable, but as the distance between media device and display increases, signal quality decreases and the more susceptible the signal becomes to magnetic interference. In fact, for distances of over 30 feet, the HDMI licensing board recommends either using a signal amplifier or considering an alternate solution, like an HDMI-over-Ethernet converter. When you’re running up against the maximum length, the greater insulation and build quality of more expensive cables can potentially improve the stability of your signal. However, if there’s a 30-foot gap between your Blu-ray player and your HDTV, you might want to rearrange some furniture. Or just use a technology designed for long distances.

The second thing to know about HDMI cables is that they are almost always expensive when you buy them at brick-and-mortar stores. If you walk into a Best Buy or Radio Shack, you can expect to pay at least $40 for a 6-foot HDMI cable. Even at discount stores like Wal-Mart and Target, the cheapest, most generic HDMI cables retail for $15 and more. Online, you’ll do a lot better on prices. Amazon.com and Monoprice.com (the “ancient custom installer’s secret”) slash even Wal-Mart’s HDMI cable prices into tiny bits. Both sites sell several models of HDMI cables for as little as $1.50. These are generally generic HDMI cables, or seldom-heard-of brands, but they work just fine for most HDTV users. We can be certain of this, because we tested them in the PCMag Labs.

Testing the Cables

We tested five cables including Monster Cable’s 1200 Higher Definition Experience Pack, a combination HDMI/Ethernet bundle that lists for $119.95 but we found for $79.95 at Amazon.com, the Monster Cable HDMI 500HD High Speed Cable ($59.95 list, we got it at Amazon for $52.62), the Spider International E-HDMI-0006 E-Series Super High Speed HDMI with Ethernet cable ($64.99 list price and a $45.29 Amazon price), the Cables Unlimited 6-Foot HDMI Male to Male Cable (PCM-2295-06) that Amazon carries for $3.19, and an unbranded, OEM cable from Monoprice that was shipped in a Belkin bag but doesn’t match any of the company’s own HDMI cables (and retails for $3.28, or $2.78 if you buy 50 cables or more).

We’ve left out some of the more lavishly expensive HDMI cables, like the AudioQuest series of HDMI cables, because they retail for nearly $700. Unless those cables can let me eat the food I see on the Food Network, they’re not worth the price of an actual HDTV.

Based purely on the cables’ specs, Monster Cable’s HDMI cables are superior. Of course, that’s because Monster Cable is the only company of the four to offer any notable specifications. Spider International and Cables Unlimited offered very little information in the way of the cables, and the generic cable had no specifications besides it being 28 AWG (American Wire Gauge), a number that simply references the width of the wire used in the cable (28 AWG is a standard measurement, though some cables can be slightly thicker at 26 or 24 AWG). HDMI standards require that all HDMI 1.4 cables be able to handle a bandwidth of 10.2 gigabits per second (Gbps). The Monster Blu-Ray 1200 Higher Definition Experience Pack has a rated speed of 17.8 Gbps. Again, what really matters is whether the cable is HDMI-1.4-compliant, and it can support the necessary features mentioned above. The higher bandwidth doesn’t matter for HDTV signals. It might make a difference with 4K-video, but since HDTVs currently top out at 1080p, that point is moot.

As long as the cable is HDMI-1.4 compliant and it can hit 10.2 Gbps, which is will if it’s 1.4-compliant, it will do the trick. Also, we couldn’t find a cable that wasn’t 1.4-compliant, so that shouldn’t be a problem.

For consistency, we used only 6-foot or 2-meter (6.6-foot) cables to ensure that cable length didn’t affect the results of the tests. We paired a Sony Bravia KDL-46EX720 3D HDTV with an LG BD670 Blu-ray player for all tests. The television was set to standard, default image settings, and the Blu-ray player was set to output only a 1080p video signal. We put the cables through three different tests: a technical quality evaluation, a blind video test, and a 3D-support test.

For the technical quality evaluation, we used the HQV video benchmark Blu-ray Disc. For each cable, we ran through the gamut of HQV video tests, which checks video for numerous image processing, frame-rate synchronization, and color-correction capabilities. The tests include numerous patterns and animations to expose possible display problems. All five cables passed HQV’s tests with flying colors, with a single exception, which was consistent across all of them (and thus more likely a flaw of either the HDTV or the Blu-ray player): 2:2 film pull-down looked a bit jerky, a minor issue that doesn’t affect the cables individual performance.

The blind video test involved the assistance of five volunteers in the PCMag Lab. They were shown the same scene from Predators on Blu-ray with different cables. They were not told which cable was which until the end of the test. No one saw any appreciable difference between the $3 cables and the $120 cable, or any of the cables in between. However, we did notice a curious phenomenon: the screen appeared slightly darker and a bit more saturated when connected to the Blu-ray player with the Monster Cable 1200 High Definition Experience Pack cable. The HDTV showed that it was receiving the same 12-bit color depth information through each cable, so the more-expensive Monster cable wasn’t pushing through more color detail. Again, the difference was minimal, and could be corrected by calibrating your HDTV.

Finally, we loaded the 3D Avatar Blu-ray to check that the cables could handle an HDMI 1.4 standard feature: 3D content. Again, every cable, including the cheap $3 cable, carried a 3D video feed to the HDTV easily.

If you’re like the vast majority of HDTV users and have a fairly simple setup that isn’t spread across a large area, there is absolutely no reason to spend more than $10 on an HDMI cable, never mind more than $100 on one. Any possible benefit that could come from an over-engineered, overpriced HDMI cable simply won’t show up in your home theater. If you’re running a 4K projector, or have a 25-foot hallway between your Blu-ray player and HDTV, or want to show off how big your home theater budget is, that’s one thing. If you just want to hook up your Blu-ray player, cable box, or video game system to your HDTV, bypass the big stores and big brands and reach into the Web bargain bin. Then use the money you saveto buy more electronics that need to be connected to one another.

No Hell. Pastor Rob Bell: What if Hell Doesn’t Exist?

I am not as liberal as Rob Bell, I believe Hell does exist, but it is only reserve for truly evil people like Mao Tse Dong or Muammar Gaddafi (maybe George W. Bush too). I definitely won’t agree only Christians can go to heaven and everybody else goes to hell.

I am joining a reading group starting in May on Rob Bell’s book “Love Wins: A Book about Heaven, Hell, and the Fate of Every Person Who Ever Lived. For those who are interested, please register here

By Jon Meacham, Thursday, Apr. 14, 2011, Times Magazine

As part of a series on peacemaking, in late 2007, Pastor Rob Bell’s Mars Hill Bible Church put on an art exhibit about the search for peace in a broken world. It was just the kind of avant-garde project that had helped power Mars Hill’s growth (the Michigan church attracts 7,000 people each Sunday) as a nontraditional congregation that emphasizes discussion rather than dogmatic teaching. An artist in the show had included a quotation from Mohandas Gandhi. Hardly a controversial touch, one would have thought. But one would have been wrong.

A visitor to the exhibit had stuck a note next to the Gandhi quotation: “Reality check: He’s in hell.” Bell was struck.

Really? he recalls thinking.

Gandhi’s in hell?

He is?

We have confirmation of this?

Somebody knows this?

Without a doubt?

And that somebody decided to take on the responsibility of letting the rest of us know?

So begins Bell’s controversial new best seller, Love Wins: A Book About Heaven, Hell, and the Fate of Every Person Who Ever Lived. Works by Evangelical Christian pastors tend to be pious or at least on theological message. The standard Christian view of salvation through the death and resurrection of Jesus of Nazareth is summed up in the Gospel of John, which promises “eternal life” to “whosoever believeth in Him.” Traditionally, the key is the acknowledgment that Jesus is the Son of God, who, in the words of the ancient creed, “for us and for our salvation came down from heaven … and was made man.” In the Evangelical ethos, one either accepts this and goes to heaven or refuses and goes to hell.

Bell, a tall, 40-year-old son of a Michigan federal judge, begs to differ. He suggests that the redemptive work of Jesus may be universal — meaning that, as his book’s subtitle puts it, “every person who ever lived” could have a place in heaven, whatever that turns out to be. Such a simple premise, but with Easter at hand, this slim, lively book has ignited a new holy war in Christian circles and beyond. When word of Love Wins reached the Internet, one conservative Evangelical pastor, John Piper, tweeted, “Farewell Rob Bell,” unilaterally attempting to evict Bell from the Evangelical community. R. Albert Mohler Jr., president of the Southern Baptist Theological Seminary, says Bell’s book is “theologically disastrous. Any of us should be concerned when a matter of theological importance is played with in a subversive way.” In North Carolina, a young pastor was fired by his church for endorsing the book.

The traditionalist reaction is understandable, for Bell’s arguments about heaven and hell raise doubts about the core of the Evangelical worldview, changing the common understanding of salvation so much that Christianity becomes more of an ethical habit of mind than a faith based on divine revelation. “When you adopt universalism and erase the distinction between the church and the world,” says Mohler, “then you don’t need the church, and you don’t need Christ, and you don’t need the cross. This is the tragedy of nonjudgmental mainline liberalism, and it’s Rob Bell’s tragedy in this book too.”

Particularly galling to conservative Christian critics is that Love Wins is not an attack from outside the walls of the Evangelical city but a mutiny from within — a rebellion led by a charismatic, popular and savvy pastor with a following. Is Bell’s Christianity — less judgmental, more fluid, open to questioning the most ancient of assumptions — on an inexorable rise? “I have long wondered if there is a massive shift coming in what it means to be a Christian,” Bell says. “Something new is in the air.”

Which is what has many traditional Evangelicals worried. Bell’s book sheds light not only on enduring questions of theology and fate but also on a shift within American Christianity. More indie rock than “Rock of Ages,” with its videos and comfort with irony (Bell sometimes seems an odd combination of Billy Graham and Conan O’Brien), his style of doctrine and worship is clearly playing a larger role in religious life, and the ferocity of the reaction suggests that he is a force to be reckoned with.

Otherwise, why reckon with him at all? A similar work by a pastor from one of the declining mainline Protestant denominations might have merited a hostile blog post or two — bloggers, like preachers, always need material — but it is difficult to imagine that an Episcopal priest’s eschatological musings would have provoked the volume of criticism directed at Bell, whose reach threatens prevailing Evangelical theology.

Bell insists he is only raising the possibility that theological rigidity — and thus a faith of exclusion — is a dangerous thing. He believes in Jesus’ atonement; he says he is just unclear on whether the redemption promised in Christian tradition is limited to those who meet the tests of the church. It is a case for living with mystery rather than demanding certitude.

From a traditionalist perspective, though, to take away hell is to leave the church without its most powerful sanction. If heaven, however defined, is everyone’s ultimate destination in any event, then what’s the incentive to confess Jesus as Lord in this life? If, in other words, Gandhi is in heaven, then why bother with accepting Christ? If you say the Bible doesn’t really say what a lot of people have said it says, then where does that stop? If the verses about hell and judgment aren’t literal, what about the ones on adultery, say, or homosexuality? Taken to their logical conclusions, such questions could undermine much of conservative Christianity.

What the Hell?

From the Apostle Paul to John Paul II, from Augustine to Calvin, Christians have debated atonement and judgment for nearly 2,000 years. Early in the 20th century, Harry Emerson Fosdick came to represent theological liberalism, arguing against the literal truth of the Bible and the existence of hell. It was time, progressives argued, for the faith to surrender its supernatural claims.

Bell is more at home with this expansive liberal tradition than he is with the old-time believers of Inherit the Wind. He believes that Jesus, the Son of God, was sacrificed for the sins of humanity and that the prospect of a place of eternal torment seems irreconcilable with the God of love. Belief in Jesus, he says, should lead human beings to work for the good of this world. What comes next has to wait. “When we get to what happens when we die, we don’t have any video footage,” says Bell. “So let’s at least be honest that we are speculating, because we are.” He is quick to note, though, that his own speculation, while unconventional, is not unprecedented. “At the center of the Christian tradition since the first church,” Bell writes, “have been a number who insist that history is not tragic, hell is not forever, and love, in the end, wins and all will be reconciled to God.”

It is also true that the Christian tradition since the first church has insisted that history is tragic for those who do not believe in Jesus; that hell is, for them, forever; and that love, in the end, will envelop those who profess Jesus as Lord, and they — and they alone — will be reconciled to God. Such views cannot be dismissed because they are inconvenient or uncomfortable: they are based on the same Bible that liberals use to make the opposite case. This is one reason religious debate can seem a wilderness of mirrors, an old CIA phrase describing the bewildering world of counterintelligence.

Still, the dominant view of the righteous in heaven and the damned in hell owes more to the artistic legacy of the West, from Michelangelo to Dante to Blake, than it does to history or to unambiguous biblical teaching. Neither pagan nor Jewish tradition offered a truly equivalent vision of a place of eternal torment; the Greek and Roman underworlds tended to be morally neutral, as did much of the Hebraic tradition concerning Sheol, the realm of the dead.

Things many Christian believers take for granted are more complicated than they seem. It was only when Jesus failed to return soon after the Passion and Resurrection appearances that the early church was compelled to make sense of its recollections of his teachings. Like the Bible — a document that often contradicts itself and from which one can construct sharply different arguments — theology is the product of human hands and hearts. What many believers in the 21st century accept as immutable doctrine was first formulated in the fog and confusion of the 1st century, a time when the followers of Jesus were baffled and overwhelmed by their experience of losing their Lord; many had expected their Messiah to be a Davidic military leader, not an atoning human sacrifice.

When Jesus spoke of the “kingdom of heaven,” he was most likely referring not to a place apart from earth, one of clouds and harps and an eternity with your grandmother, but to what he elsewhere called the “kingdom of God,” a world redeemed and renewed in ways beyond human imagination. To 1st century ears in ancient Judea, Jesus’ talk of the kingdom was centered on the imminent arrival of a new order marked by the defeat of evil, the restoration of Israel and a general resurrection of the dead — all, in the words of the prayer he taught his disciples, “on earth.”

There is, however, no escaping the fact that Jesus speaks in the Bible of a hell for the “condemned.” He sometimes uses the word Gehenna, which was a valley near Jerusalem associated with the sacrifice of children by fire to the Phoenician god Moloch; elsewhere in the New Testament, writers (especially Paul and John the Divine) tell of a fiery pit (Tartarus or Hades) in which the damned will spend eternity. “Depart from me, you cursed [ones], into the eternal fire prepared for the devil and his angels,” Jesus says in Matthew. In Mark he speaks of “the unquenchable fire.” The Book of Revelation paints a vivid picture — in a fantastical, problematic work that John the Divine says he composed when he was “in the spirit on the Lord’s day,” a signal that this is not an Associated Press report — of the lake of fire and the dismissal of the damned from the presence of God to a place where “they will be tormented day and night for ever and ever.”

And yet there is a contrary scriptural trend that suggests, as Jesus puts it, that the gates of hell shall not finally prevail, that God will wipe away every tear — not just the tears of Evangelical Christians but the tears of all. Bell puts much stock in references to the universal redemption of creation: in Matthew, Jesus speaks of the “renewal of all things”; in Acts, Peter says Jesus will “restore everything”; in Colossians, Paul writes that “God was pleased to … reconcile to himself all things, whether things on earth or things in heaven.”

So is it heaven for Christians who say they are Christians and hell for everybody else? What about babies, or people who die without ever hearing the Gospel through no fault of their own? (As Bell puts it, “What if the missionary got a flat tire?”) Who knows? Such tangles have consumed Christianity for millennia and likely will for millennia to come.

What gives the debate over Bell new significance is that his message is part of an intriguing scholarly trend unfolding simultaneously with the cultural, generational and demographic shifts made manifest at Mars Hill. Best expressed, perhaps, in the work of N.T. Wright, the Anglican bishop of Durham, England (Bell is a Wright devotee), this school focuses on the meaning of the texts themselves, reading them anew and seeking, where appropriate, to ask whether an idea is truly rooted in the New Testament or is attributable to subsequent church tradition and theological dogma.

For these new thinkers, heaven can mean different things. In some biblical contexts it is a synonym for God. In others it signifies life in the New Jerusalem, which, properly understood, is the reality that will result when God brings together the heavens and the earth. In yet others it seems to suggest moments of intense human communion and compassion that are, in theological terms, glimpses of the divine love that one might expect in the world to come. One thing heaven is not is an exclusive place removed from earth. This line of thinking has implications for the life of religious communities in our own time. If the earth is, in a way, to be our eternal home, then its care, and the care of all its creatures, takes on fresh urgency.

Bell’s Journey

The easy narrative about Bell would be one of rebellion — that he is reacting to the strictures of a suffocating childhood by questioning long-standing dogma. The opposite is true. Bell’s creed of conviction and doubt — and his comfort with ambiguity and paradox — comes from an upbringing in which he was immersed in faith but encouraged to ask questions. His father, a central figure in his life, is a federal judge appointed by President Reagan in 1987. (Rob still remembers the drive to Washington in the family Oldsmobile for the confirmation hearings.) “I remember him giving me C.S. Lewis in high school,” Bell says. “My parents were both very intellectually honest, straightforward, and for them, faith meant that you were fully engaged.” As they were raising their family, the Bells, in addition to regular churchgoing, created a rigorous ethos of devotion and debate at home. Dinner-table conversations were pointed; Lewis’ novels and nonfiction were required reading.

The roots of Love Wins can be partly traced to the deathbed of a man Rob Bell never met: his grandfather, a civil engineer in Michigan who died when Rob’s father was 8. The Bells’ was a very conservative Evangelical household. When the senior Bell died, there was to be no grief. “We weren’t allowed to mourn, because the funeral of a Christian is supposed to be a celebration of the believer in heaven with Jesus right now,” says Robert Bell Sr. “But if you’re 8 years old and your dad — the breadwinner — just died, it feels different. Sad.”

The story of how his dad, still a child, was to deal with death has stayed with Rob. “To weep, to shed any tears — that would be doubting the sovereignty of God,” Rob says now, looking back. “That was the thing — ‘They’re all in heaven, so we’re happy about that.’ It doesn’t matter how you are actually humanly responding to this moment …” Bell pauses and chuckles ironically, a bit incredulous. “We’re all just supposed to be thrilled.”

Robby — his mother still calls him that — was emotionally precocious. “When he was around 10 years old, I detected that he had a great interest and concern for people,” his father says. “There he’d be, riding along with me, with his little blond hair, going to see sick folks or friends who were having problems, and he would get back in the truck after a visit and begin to analyze them and their situations very acutely. He had a feel for people and how they felt from very early on.”

Rob was a twice-a-week churchgoer at the Baptist and nondenominational churches the family attended at different times — services on Sunday, youth group on Wednesday. He recalls a kind of quiet frustration even then. “I remember thinking, ‘You know, if Jesus is who this guy standing up there says he is, this should be way more compelling.’ This should have a bit more electricity. The knob should be way more to the right, you know?”

Music, not the church, was his first consuming passion. (His wife Kristen claims he said he wanted to be a pastor when they first met early on at Wheaton College in Illinois. Bell is skeptical: “I swear to this day that that was a line.”) He and some friends started a band when he was a sophomore. “I had always had creative energy but no outlet,” he says. “I really discovered music, writing and playing, working with words and images and metaphors. You might say the music unleashed a monster.”

The band became central to him. Then two things happened: the guitar player decided to go to seminary, and Bell came down with viral meningitis. “It took the wind out of our sails,” he says. “I had no Plan B. I was a wreck. I was devastated, because our band was going to make it. We were going to live in a terrible little house and do terrible jobs at first, because that’s what great bands do — they start out living in terrible little houses and doing terrible little jobs.” His illness — “a freak brain infection” — changed his life, Bell says.

At 21, Rob was teaching barefoot waterskiing at HoneyRock Camp, near Three Lakes, Wis., when he preached his first sermon. “I didn’t know anything,” he says. “I took off my Birkenstocks beforehand. I had this awareness that my life would never be the same again.” The removal of the shoes is an interesting detail for Bell to remember. (“Do not come any closer,” God says to Moses in the Book of Exodus. “Take off your sandals, for the place where you are standing is holy ground.”) Bell says it was just intuitive, but the intuition suggests he had a sense of himself as a player in the unfolding drama of God in history. “Create things and share them,” Bell says. “It all made sense. That moment is etched. I remember thinking distinctly, ‘I could be terrible at this.’ But I knew this would get me up in the morning. I went to Fuller that fall.”

Fuller Theological Seminary, in Pasadena, Calif., is an eclectic place, attracting 4,000 students from 70 countries and more than 100 denominations. “It’s pretty hard to sit with Pentecostals and Holiness people and mainline Presbyterians and Anglicans and come away with a closed mind-set that draws firm boundaries about theology,” says Fuller president Richard Mouw.

After seminary, Bell’s work moved in two directions. He was recovering the context of the New Testament while creating a series of popular videos on Christianity called Nooma, Greek for wind or spirit. He began to attract a following, and Mars Hill — named for the site in Athens where Paul preached the Christian gospel of resurrection to the pagan world — was founded in Grand Rapids, Mich., in 1999. “Whenever people wonder why a church is growing, they say, ‘He’s preaching the Bible.’ Well, lots of people are preaching the Bible, and they don’t have parking problems,” says Bell.

Mars Hill did have parking problems, and Bell’s sudden popularity posed some risks for the young pastor. Pride and self-involvement are perennial issues for ministers, who, like politicians, grow accustomed to the sound of their own voices saying Important Things and to the deference of the flock. By the time Bell was 30, he was an Evangelical celebrity. (He had founded Mars Hill when he was 28.) He was referred to as a “rock star” in this magazine. “There was this giant spotlight on me,” he says. “All of a sudden your words are parsed. I found myself — and I think this happens to a lot of people — wanting to shrink away from it. But I decided, Just own it. I’m very comfortable in a room with thousands of people. I do have this voice. What will I say?”

And how will he say it? The history of Evangelism is in part the history of media and methods: Billy Sunday mastered the radio, Billy Graham television; now churches like Bell’s are at work in the digital vineyards of downloads and social media. Demography is also working in Bell’s favor. “He’s trying to reach a generation that’s more comfortable with mystery, with unsolved questions,” says Mouw, noting that his own young grandchildren are growing up with Hindu and Muslim friends and classmates. “For me, Hindus and Muslims were the people we sent missionaries off to in places we called ‘Arabia,'” Mouw says. “Now that diversity is part of the fabric of daily life. It makes a difference. My generation wanted truth — these are folks who want authenticity. The whole judgmentalism and harshness is something they want to avoid.”

If Bell is right about hell, then why do people need ecclesiastical traditions at all? Why aren’t the Salvation Army and the United Way sufficient institutions to enact a gospel of love, sparing us the talk of heaven and hellfire and damnation and all the rest of it? Why not close up the churches?

Bell knows the arguments and appreciates the frustrations. “I don’t know anyone who hasn’t said, ‘Let’s turn out the lights and say we gave it a shot,'” he says. “But you can’t — I can’t — get away from what this Jesus was, and is, saying to us. What the book tries to do is park itself right in the midst of the tension with a Jesus who offers an urgent and immediate call — ‘Repent! Be transformed! Turn!’ At the same time, I’ve got other sheep. There’s a renewal of all things. There’s water from the rock. People will come from the East and from the West. The scandal of the gospel is Jesus’ radical, healing love for a world that’s broken.”

Fair enough, but let’s be honest: religion heals, but it also kills. Why support a supernatural belief system that, for instance, contributed to that minister in Florida’s burning of a Koran, which led to the deaths of innocent U.N. workers in Afghanistan?

“I think Jesus shares your critique,” Bell replies. “We don’t burn other people’s books. I think Jesus is fairly pissed off about it as well.”

On Sunday, April 17, at Mars Hill, Bell will be joined by singer-songwriter Brie Stoner (who provided some of the music for his Nooma series) and will teach the first 13 verses of the third chapter of Revelation, which speaks of “the city of my God, the new Jerusalem, which is coming down out of heaven from my God … Whoever has ears, let them hear what the Spirit says to the churches.” The precise meaning of the words is open to different interpretations. But this much is clear: Rob Bell has much to say, and many are listening.

The Terror of Code in the Wrong Hands

Here is a new term, software terrorist, who brings negative productivity to the team. I can attest that catching bug in poorly written code waste a lot more time than rewriting the code myself from scratch.

By Allen Holub, May 2005, SD Times

The 20-to-1 productivity rule says that 5 percent of programmers are 20 times more productive than the remaining 95 percent, but what about the 5 percent at the other end of the bell curve? Consider the software terrorist: the guy who stays up all night, unwittingly but systematically destroying the entire team’s last month’s work while “improving” the code. He doesn’t tell anybody what he’s done, and he never tests. He’s created a ticking time bomb that won’t be discovered for six months.

When the bomb goes off, you can’t roll back six months of work by the whole team, and it takes three weeks of your best programmer’s effort to undo the damage. Meanwhile, our terrorist gets a raise because he stays late so often, working so hard. The brilliant guy who cleans up the debris gets a bad performance review because his schedule has slipped, so he quits.

Valuable tools in the hands of experts become dangerous weapons in the hands of terrorists. The terrorist doesn’t understand how to use generics, templates and casts, and so with a single click on the “refactor” button he destroys the program’s carefully crafted typing system. That single-click refactor is a real time saver for the expert. Scripting languages, which in the right hands save time, become a means for creating write-only code that has to be scrapped after you’ve spent two months trying to figure out why it doesn’t work.

Terrorist scripts can be so central to the app, and so hard to understand, that they sometimes remain in the program, doubling the time required for all maintenance efforts. Terrorist documentation is a font of misinformation. Terrorist tests systematically destroy the database every time they’re run.

Terrorist work isn’t just nonproductive, it’s anti-productive. A terrorist reduces your team’s productivity by at least an order of magnitude. It takes a lot longer to find a bug than to create one. None of the terrorist code ends up in the final program because it all has to be rewritten. You pay the terrorists, and you also pay 10 times more to the people who have to track down and fix their bugs.

Given the difficulty that most organizations have in firing (or even identifying) incompetent people, the only way to solve this problem is not to hire terrorists at all; but the terrorists are masters of disguise, particularly in job interviews. They talk a good game, they have lots of experience, and they have great references because they work so hard.

Since the bottom 5 percent is indistinguishable from the rest of the bottom 95 percent, the only way to avoid hiring terrorists is to avoid hiring from the remaining 95 percent altogether.

The compelling reason for this strategy is that the 20-to-1 rule applies only when elite programmers work exclusively with other elite programmers. Single elite programmers who interact with 10 average programmers waste most of their time explaining and helping rather than working. Two elite programmers raise the productivity of a 20-programmer group by 10 percent. It’s like getting two programmers for free. Two elite programmers working only with each other do the work of at least 20 average programmers. It’s like getting 18 programmers for free. If you pay them twice the going salary (and you should if you want to keep them), you’re still saving vast amounts of money.

Unfortunately, it’s possible for a software terrorist to masquerade as an elite programmer, but this disguise is easier to detect. Programmers who insist on working in isolation (especially the ones who come to work at 4:00 p.m. and stay all night), the prima donnas who have fits when they don’t get their way, the programmers who never explain what they’re doing in a way that anyone else can understand and don’t document their code, the ones that reject new technologies or methodologies out of hand rather than showing genuine curiosity—these are the terrorists.

Avoid them no matter how many years of experience they have.

Software terrorism is on the upswing. I used to quote the standard rule that the top 10 percent were 10 times more productive. The hiring practices prevalent since the dot-com explosion—which seem to reject the elite programmers by design—have lowered the general skill level of the profession, however.

As the number of elite programmers gets smaller, their relative productivity gets higher. The only long-term solution to this problem is to change our hiring practices and our attitudes toward training. The cynic in me has a hard time believing that either will happen, but we can always hope for the best.

Therapist-free therapy

Looks like psychologist will be out of work soon and they will be replaced by computer programs. I never trust those talk therapy anyways, the couch only works in the movies.

Mar 3rd 2011, The Economist
Cognitive-bias modification may put the psychiatrist’s couch out of business

THE treatment, in the early 1880s, of an Austrian hysteric called Anna O is generally regarded as the beginning of talking-it-through as a form of therapy. But psychoanalysis, as this version of talk therapy became known, is an expensive procedure. Anna’s doctor, Josef Breuer, is estimated to have spent over 1,000 hours with her.

Since then, things have improved. A typical course of a modern talk therapy, such as cognitive behavioural therapy, consists of 12-16 hour-long sessions and is a reasonably efficient way of treating conditions like depression and anxiety (hysteria is no longer a recognised diagnosis). Medication, too, can bring rapid change. Nevertheless, treating disorders of the psyche is still a hit-and-miss affair, and not everyone wishes to bare his soul or take mind-altering drugs to deal with his problems. A new kind of treatment may, though, mean he does not have to. Cognitive-bias modification (CBM) appears to be effective after only a few 15-minute sessions, and involves neither drugs nor the discussion of feelings. It does not even need a therapist. All it requires is sitting in front of a computer and using a program that subtly alters harmful thought patterns.

This simple approach has already been shown to work for anxiety and addictions, and is now being tested for alcohol abuse, post-traumatic-stress disorder and several other disturbances of the mind. It is causing great excitement among researchers. As Yair Bar-Haim, a psychologist at Tel Aviv University who has been experimenting with it on patients as diverse as children and soldiers, puts it, “It’s not often that a new evidence-based treatment for a major psychopathology comes around.”

CBM is based on the idea that many psychological problems are caused by automatic, unconscious biases in thinking. People suffering from anxiety, for instance, may have what is known as an attentional bias towards threats: they are drawn irresistibly to things they perceive to be dangerous. Similar biases may affect memory and the interpretation of events. For example, if an acquaintance walks past without saying hello, it might mean either that he has ignored you or that he has not seen you. The anxious, according to the theory behind CBM, have a bias towards assuming the former and reacting accordingly.

The goal of CBM is to alter such biases, and doing so has proved surprisingly easy. A common way of debiasing attention is to show someone two words or pictures—one neutral and the other threatening—on a computer screen. In the case of social anxiety these might be a neutral face and a disgusted face. Presented with this choice, an anxious person instinctively focuses on the disgusted visage. The program, however, prods him to complete tasks involving the neutral picture, such as identifying letters that appear in its place on the screen. Repeating the procedure around a thousand times, over a total of two hours, changes the user’s tendency to focus on the anxious face. That change is then carried into the wider world.

Emily Holmes of Oxford University, who studies the use of CBM for depression, describes the process as like administering a cognitive vaccine. When challenged by reality in the form of, say, the unobservant friend, the recipient of the vaccine finds he is inoculated against inappropriate anxiety.

In a recent study of social anxiety by Norman Schmidt of Florida State University and his colleagues, which involved 36 volunteers who had been diagnosed with anxiety, half underwent eight short sessions of CBM and the rest were put in a control group and had no treatment. At the end of the study, a majority of the CBM volunteers no longer seemed anxious, whereas in the control group only 11% had shed their anxiety. Although it was only a small trial, these results compare favourably with those of existing treatments. An examination of standard talk therapy carried out in 2004, for instance, found that half of patients had a clinically significant reduction in symptoms. Trials of medications have similar success rates.

The latest research, which is on a larger scale and is due to be published this month in Psychological Science, tackles alcohol addiction. Past work has shown that many addicts have an approach bias for alcohol—in other words, they experience a physical pull towards it. (Arachnophobia, a form of this bias that is familiar to many people, works in the opposite way: if they encounter a spider, they recoil.)

This study, conducted by Reinout Wiers of the University of Amsterdam and his colleagues, attempted to correct the approach bias to alcohol with CBM. The 214 participants received either a standard addiction treatment—a form of talk therapy—or the standard treatment plus four 15-minute sessions of CBM. In the first group, 41% of participants were abstinent a year later; in the second, 54%. That is not a cure for alcoholism, but it is a significant improvement on talk therapy alone.

Many other researchers are now exploring CBM. A team at Harvard, led by Richard McNally, is seeking volunteers for a month-long programme that will use smart-phones to assess the technique’s effect on anxiety. And Dr Bar-Haim and his team are examining possible connections between cognitive biases and post-traumatic-stress disorder in the American and Israeli armies.

Not all disorders are amenable to CBM. One study, by Hannah Reese (also at Harvard) and her colleagues, showed that it is ineffective in countering arachnophobia (perhaps not surprising, since this may be an evolved response, rather than an acquired one). Moreover, Dr Wiers found that the approach bias towards alcohol is present in only about half of the drinkers he studies. He hypothesises that for the others, drinking is less about automatic impulses and more about making a conscious decision. In such cases CBM is unlikely to work.

Colin MacLeod of the University of Western Australia, one of the pioneers of the technique, thinks CBM is not quite ready for general use. He would like to see it go through some large, long-term, randomised clinical trials of the sort that would be needed if it were a drug, rather than a behavioural therapy. Nevertheless, CBM does look extremely promising, if only because it offers a way out for those whose answer to the question, “Do you want to talk about it?” is a resounding “No”
