Tories embark on late-summer campaign to woo Quebec voters
'The End of Summer Tour is for us to make political gains,' Denis Lebel tells Mount Royal crowd
Federal Conservatives are capping off their summer with a pre-electoral push in Quebec, a charm campaign to help the party rebound in what has proven to be challenging terrain.
Denis Lebel, the prime minister's Quebec lieutenant, is banking on his 12-day "End of Summer Tour" to court a province where the Conservatives hold only five seats and recent polls have suggested they trail the New Democrats, Liberals and Bloc Quebecois in popular support.
Even though the next election could be more than a year away, Lebel has been shaking hands and delivering speeches across the province on a trek that wraps up Thursday in Quebec City.
"We wanted to be sure that everybody in Quebec understands that Quebec is very important for our government," Lebel told a crowd of about 100 supporters at a rally this week in Montreal's Mount Royal riding, a district long coveted by the Conservatives.
"The End of Summer Tour is for us to make political gains. We have worked very hard to make political gains in Quebec, everywhere, in all regions."
He told the audience that the drive started months before he kicked off his tour, with 12 cabinet ministers from outside the province paying visits to Quebec since April.
Citizenship and Immigration Minister Chris Alexander as well as Lynne Yelich, junior minister responsible for consular affairs, accompanied Lebel at the Mount Royal event.
Polls show Tories trailing in Quebec
A Leger poll taken in June found the Conservatives had the support of only 12 per cent of Quebecers, compared with 34 per cent for both the NDP and Liberals and 17 per cent for the Bloc.
Polls conducted more recently suggest the Liberals have gained ground in regions like Ontario and the Maritimes at the expense of the Tories, which could make additional wins in Quebec even more important.
"If the Tories lose seats elsewhere, they're going to have to find places to make those up," said David Coletto, chief executive officer of research company Abacus Data.
"I think in their mind if they can regain five seats in Quebec ... that probably can at least offset what will likely be some losses in Atlantic Canada and other parts of the country."
But Coletto said the Tories' growth potential in Quebec appears limited, particularly since recent surveys have found its support has hovered between 12 and 20 per cent — similar to its level after the 2011 election.
Even the turmoil within the Bloc, now reduced to two MPs, could hurt the Conservatives' chances of a turnaround, he added.
Recent data from his firm has suggested that only 11 per cent of Bloc voters have a positive view of Harper, 50 per cent have a favourable view of NDP Leader Thomas Mulcair and 27 per cent hold a positive view of Liberal Leader Justin Trudeau.
In 2011, the Conservatives lost six of the 11 ridings they held in Quebec following a surge in popularity of the NDP and then-leader Jack Layton.
Harper cabinet ministers Lawrence Cannon, Jean-Pierre Blackburn and Josee Verner were all defeated.
The Quebec City region, where the Conservatives lost three seats in 2011, would likely be a focal point of any Tory revival in the province.
$500-per-head Quebec City fundraiser planned
To help replenish Tory coffers, a party source says the Conservatives are organizing a $500-per-person fundraising dinner in Quebec City on Sept. 8.
Lebel and Alexander both expressed confidence their party will bounce back.
Following the Mount Royal rally, Alexander predicted to reporters that the Conservatives would add new cabinet ministers in Quebec after the 2015 election.
When asked how many, he directed the question to Lebel, who replied: "As many as possible, for sure."
The Tories will once again target Mount Royal as a potential beachhead in Montreal, where the party hasn't won a seat in a quarter-century.
In 2011, Tory candidate Saulie Zajdel finished about 2,300 votes behind popular Liberal incumbent Irwin Cotler in the riding previously held by Pierre Elliott Trudeau.
Cotler has announced he will not seek re-election in the district, which is home to a large Jewish population.
In his speech, Lebel told the Mount Royal crowd that Harper's foreign policy has helped Canada become Israel's "best friend."
"Obviously, our government is taking a strong stance on the right of Israel, not only to exist but also to defend its citizens," Lebel said, drawing a big applause.
Lebel 'determined to win' Mount Royal
"As you know, Mount Royal is a riding we are determined to win — we came pretty close ... But this time we will have to seal the deal."
The Conservatives will run another candidate there in the next election.
Zajdel was arrested last year as part of Quebec's anti-corruption crackdown.
He was charged with alleged crimes police say took place between 2007 and 2008 when he was a municipal councillor.
Robert Libman, a prominent figure in the area who's served as a local mayor and a provincial politician, has said he's decided to seek the nomination in large part due to Harper's Middle East approach and his economic policy.
"I think our riding is ready to make the switch after voting Liberal since 1940," said Libman, who, as a member of the Equality party, won a provincial riding in the area that had long been a rock-solid Liberal seat.
'It's important to be visible in politics'
"As I proved in 1989, if you work hard enough, and if the circumstances are working in a certain way around certain issues, you can turn the tide."
Lebel's cross-Quebec tour has taken him to a poutine festival, a lunch event at a Royal Canadian Legion and a riding where a Conservative incumbent lost a nail-biter in 2011.
Bernard Genereux thought he had retained his seat in Montmagny-L'Islet-Kamouraska-Riviere-du-Loup, but a recount revealed he had lost to the NDP's Francois Lapointe — by nine votes.
Genereux, who's seeking the nomination once again, said several cabinet ministers from outside Quebec have also visited the area in recent months.
"There's nothing exceptional about what's happening right now," said Genereux, who thinks recent attention paid by the Tories was similar in the lead-up to 2011.
"It's important to be visible in politics."

SAN DIEGO – Tiger Woods cared more about the number of rounds left at Torrey Pines than the number of PGA Tour wins belonging to the guys chasing him.
When the second round ended Friday in a steady rain at the Farmers Insurance Open, the odds looked to be stacked in Woods' favor. He had a 7-under 65 on the North Course for his first outright 36-hole lead on the PGA Tour in more than three years. He is a seven-time winner at Torrey Pines, six of those in this tournament. And his 74 career wins on tour were 74 more than the next seven guys behind him.
"We've got a long way to go," Woods said after finishing his two rounds at 11-under 133.
Woods knows this from experience.
His three-shot win in the 2009 Buick Open was tougher than it looked on paper, only because Woods had everything to lose. He was expected to win. Of the 13 players within five shots of his slim lead going into the last round, only one of them — Ben Crane at No. 73 — was ranked inside the top 100 in the world.
Golf gets deeper every year, and it doesn't get any easier to win.
Then again, Woods is playing some pretty good golf.
He effectively missed only one fairway on the easier North Course in the second round. He is leading the field in driving distance at 318.5 yards, remarkable given the wet conditions from the rain and Torrey Pines being at sea level. He is 9 under on the par 5s, with five birdies and two eagles over the last two days.
Woods seized control Friday around the turn, when he played four holes in 5-under par — a 25-foot birdie putt on the 17th, a 5-iron to 5 feet for eagle on No. 18, a two-putt birdie on the first, and a wedge that one-hopped against the pin and settled about 5 feet away for another birdie.
"Vintage (at)TigerWoods today," Dustin Johnson said on Twitter after finishing eight shots behind.
Woods had a two-shot lead over Billy Horschel, who only two months ago was in Q-school trying to get his PGA Tour card again. Horschel finished strong on the South Course for a 69 and was thrilled when he looked at the leaderboard. He was at 9-under 135, and Woods was the only name ahead of him. That meant he would be in the final group with Woods, joined by Web.com Tour grad Casey Wittenberg, who had a 67 on the North.
"It's a good day and I'm excited about tomorrow — I get to play with Tiger," Horschel said. "I found out when I tapped in for par. I realized he was leading and I was in second place. So yeah, looking forward to that."
Horschel wades into a big world Saturday, but he believes he has the experience from when he played the Walker Cup in 2007 at Royal County Down.
"There was a guy I competed against three times called Rory McIlroy," Horschel said. "So there may have been 10, 12,000 people following us, and only a couple thousand following the rest of the groups. So I've dealt with crowds. I guess it's a little bit easier playing with Tiger because I guess the group ahead, they move a lot or something. Just hearing what media says. It's going to be exciting."
Brad Fritsch, a rookie from Canada, had a 67 on the South Course to lead the group of six players at 8-under 136. The others were Wittenberg, Steve Marino, Jimmy Walker, Josh Teater and Erik Compton, whom Woods referred to as "remarkable" for being a two-time heart transplant recipient and playing on the PGA Tour.
Defending champion Brandt Snedeker didn't fare so well. After opening with a 65 on the North, he made only one birdie and twice took bogey on the par 5s on his way to a 75 that left him seven shots behind. K.J. Choi, who had a 65 on the South Course, couldn't break par on the easier North and had a 73 to fall five behind.
Phil Mickelson struggled to keep his hands dry in the wet weather and finished bogey-bogey on the South for a 71 to make the cut on the number, though his work isn't over. There were 87 players who made the cut at 1-under 143, meaning there will be another cut to top 70 and ties Saturday.
Mike Weir, meanwhile, made the cut for the first time since July 2011 despite a sloppy finish for a 75 on the South. He was tied for 41st at 3-under 141.
Woods is coming off a missed cut in Abu Dhabi last week to start his year.
"I've had beautiful practice sessions at home," he said. "If I can do it there, I can do it out here. Even though last week I played only two days, I felt like I hit the ball well enough to shoot a better score than I did. I had a couple of days to work on it, and I came out here and felt pretty good about it."
The final two rounds move to the South Course, which played about 1½ shots harder Friday in the rain. The greens are more receptive, sure, but the course figures to play at full length in wet conditions and at sea level.
For Woods, it was his first outright lead going into the weekend against a full field since the Australian Open in 2011 (he finished third at The Lakes), and his first time atop the leaderboard at Torrey Pines since 2008. Then again, he has only played one time at this event since then when he was just starting to change his swing.
And while this looks ominous for everyone else, Woods with a 36-hole lead — even at Torrey Pines — doesn't mean this is over. He had a 34-10 record when he has at least a share of the 36-hole lead, though he has failed to win four of the last six times from that spot.

America's urban barbecue boom is often driven by entrepreneurs looking to emulate regional icons they see on TV—typically Memphis pulled pork and Texas brisket. But in Chicago, the trend for newcomers to look outward ignores the rich smoked-meat tradition in their very own backyard.
A true regional style develops out of local conditions. Chicago's indigenous South Side, African-American barbecue style may not be a major one next to Memphis or Texas, but it's real all the same, with its own distinctive story.
It started, like Chicago blues, with migrants from the Mississippi Delta after World War II. A group of brothers from Indianola, Mississippi named Collins opened grocery stores and prepared takeout barbecue on weekends, which grew into actual barbecue stands. They cooked pork because that's what they'd cooked at home, and the Chicago stockyards had plenty of it; they cooked spareribs and even rib tips, the scrap piece filled with cartilage, which the stockyards gave away for free.
And because Chicago was a town full of Eastern Europeans, pitmasters had access to another scrap meat—sausage. Ribs, rib tips, and hot links remain the holy smoke trinity, cooked relatively quickly (for barbecue) over a roaring hickory pit to a point definitely chewier than "fall off the bone."
Which leads to the other distinctive sign of Chicago barbecue—the steel and glass pit, often called an "aquarium smoker." In the 1950s, the health department wasn't fond of grimy brick pits that were common down south, so a local metal fabricator devised a pit that could be taken apart and hosed down. It was the Collins brothers who noticed that it also made a great display case in your stand's front window.
In the 1950s and 1960s, independent barbecue businesses became symbols of black economic empowerment, and their owners became important local backers of the civil rights struggle, supporting Martin Luther King's protests in Chicago, and breaking down barriers by getting black-owned products (like Argia B. Collins' Mumbo Sauce) into white-owned grocery chains.
South Side Chicago stands differ from the roadside joints you see in Texas or the Carolinas—they're take-out only, which usually requires you to dine on the trunk of your car—but chat up the folks in line at Lem's or Honey 1 and you'll find a vibrant kinship of barbecue.
From caramel cake to hickory-smoked ribs, here's what to look for in Chicago's barbecue scene.

The Great Mental Models Volumes One and Two are out.
Learn more about the project here.
Understanding your circle of competence helps you avoid problems, identify opportunities for improvement, and learn from others.
The concept of the Circle of Competence has been used over the years by Warren Buffett as a way to focus investors on only operating in areas they knew best. The bones of the concept appear in his 1996 Shareholder Letter:
What an investor needs is the ability to correctly evaluate selected businesses. Note that word "selected": You don't have to be an expert on every company, or even many. You only have to be able to evaluate companies within your circle of competence. The size of that circle is not very important; knowing its boundaries, however, is vital.
Circle Of Competence
Circle of Competence is simple: Each of us, through experience or study, has built up useful knowledge on certain areas of the world. Some areas are understood by most of us, while some areas require a lot more specialty to evaluate.
For example, most of us have a basic understanding of the economics of a restaurant: You rent or buy space, spend money to outfit the place and then hire employees to seat, serve, cook, and clean. (And, if you don't want to do it yourself, manage.)
From there, it's a matter of generating enough traffic and setting the appropriate prices to generate a profit on the food and drinks you serve—after all of your operating expenses have been paid. Though the cuisine, atmosphere, and price points will vary by restaurant, they all have to follow the same economic formula.
That basic knowledge, along with some understanding of accounting and a little bit of study, would enable one to evaluate and invest in any number of restaurants and restaurant chains, public or private. It's not all that complicated.
However, can most of us say we understand the workings of a microchip company or a biotech drug company at the same level? Perhaps not.
"I'm no genius. I'm smart in spots—but I stay around those spots."— Tom Watson Sr., Founder of IBM
But as Buffett so eloquently put it, we do not necessarily need to understand these more esoteric areas to invest capital. Far more important is to honestly define what we do know and stick to those areas. Our circle of competence can be widened, but only slowly and over time. Mistakes are most often made when straying from this discipline.
Circle of Competence applies outside of investing.
Buffett describes the circle of competence of one of his business managers, a Russian immigrant with poor English who built the largest furniture store in Nebraska:
I couldn't have given her $200 million worth of Berkshire Hathaway stock when I bought the business because she doesn't understand stock. She understands cash. She understands furniture. She understands real estate. She doesn't understand stocks, so she doesn't have anything to do with them. If you deal with Mrs. B in what I would call her circle of competence… She is going to buy 5,000 end tables this afternoon (if the price is right). She is going to buy 20 different carpets in odd lots, and everything else like that [snaps fingers] because she understands carpet. She wouldn't buy 100 shares of General Motors if it was at 50 cents a share.
It did not hurt Mrs. B to have such a narrow area of competence. In fact, one could argue the opposite. Her rigid devotion to that area allowed her to focus. Only with that focus could she have overcome her handicaps to achieve such extreme success.
In fact, Charlie Munger takes this concept outside of business altogether and into the realm of life in general. The essential question he sought to answer: Where should we devote our limited time in life, to achieve the most success? Charlie's simple prescription:
You have to figure out what your own aptitudes are. If you play games where other people have the aptitudes and you don't, you're going to lose. And that's as close to certain as any prediction that you can make. You have to figure out where you've got an edge. And you've got to play within your own circle of competence.
If you want to be the best tennis player in the world, you may start out trying and soon find out that it's hopeless—that other people blow right by you. However, if you want to become the best plumbing contractor in Bemidji, that is probably doable by two-thirds of you. It takes a will. It takes the intelligence. But after a while, you'd gradually know all about the plumbing business in Bemidji and master the art. That is an attainable objective, given enough discipline. And people who could never win a chess tournament or stand in center court in a respectable tennis tournament can rise quite high in life by slowly developing a circle of competence—which results partly from what they were born with and partly from what they slowly develop through work.
So, the simple takeaway here is clear. If you want to improve your odds of success in life and business, then define the perimeter of your circle of competence, and operate inside. Over time, work to expand that circle but never fool yourself about where it stands today, and never be afraid to say "I don't know."
Circle of Competence is part of the Farnam Street latticework of mental models.

My nolo controllers are on the floor in vridge 2.0 despite multiple room setup,i dont have this problem with the classic version.ReplyDelete
So I've created a bug? I installed the desktop app, installed vridge 2.0 on phone, and connected fine. I was installing steamvr when i noticed the settings icon on my phone. I seen i could chose different headsets, selected google cardboard and the screen changed to a narrower settings. I was curious what google daydream looked like and this is where the problem has started. It wanted me to install google daydream, then the daydream keyboard, and then it wants to pair with bluetooth controller. I dont have google daydream, I just wanted to see what it changed. Im now stuck with this setting. Ive uninstalled the app, deleted the cache on my phone, rebooted my phone, but when i reinstall the vridge app, it immediately goes to that google daydream screen of wanting to connect to bluetooth remote. I can not find how to either delete a setting in a root folder, or in the app change it back from google daydream to google cardboard. Any help in getting this back to default settings would be appreciated.ReplyDelete
I have no positional head tracking with NOLO and Riftcat 2.0.3ReplyDelete
It was working fine with the earlier 2.0 beta, and it still works fine with Riftcat 1.5, iVRy, or the NOLO vizualizer.
I am unable to connect using USB Tethering. I set it up and it says "Is this your phone?" I click yeas and then it looks like it tries to connect for about 1 second before it says again "Is this your phone?" over and over.ReplyDelete
You must change firewall rule.ReplyDelete
Great news! This update looks very promising, congratulations!ReplyDelete

I have a Huawei P7 that works great with Trinus, steamVR and Moonlight (not both at the sametime), but Google Play says my phone is not compatible with vridge, is there a way to change this? Can i download the APK???ReplyDelete
Hallo everybody, i'm trying to play Alien Isolation on my smartphone. I got the game on Steam patched with the latest Mothervr dll, Moonlight enabled both on my pc and smartphone, room calibration done and Steamvr ready... but whean i start the game all I can see is a black screen on pc and smartphone while audio is working. Can anybody tell me what's going on? I don't understand if I'm doing something wrong or if it's Alien Isolation that can not be played in this way.ReplyDelete
I keep trying and can't make this work with my Samsung Note 8 and Gear VR. I just downloaded the new 2.0 and the SideloadVR but it won't connect.ReplyDelete
Alright! Is it possible to have the phone directly connect to the computer with wifi and not using a router (I see that what I am suggesting doesn't exist yet)? If possible, it'd be great for those like me who can't tether because of hotspot subscriptions and when other people are using the same router as you. Or is it too big of a hurdle to program?ReplyDelete

Constructal design: geometric optimization of micro-channel heat sinks
T. Bello-Ochende†; L. Liebenberg; J.P. Meyer
Department of Mechanical and Aeronautical Engineering, University of Pretoria, Pretoria 0002, South Africa
This paper reports numerical optimization results for three-dimensional heat and fluid flow in a rectangular micro-channel heat sink using water as the cooling fluid. The conducting heat sink consists of silicon wafer. Numerical simulation was conducted on a unit cell which is a micro-channel heat sink with a fixed volume of 0.9 mm3 and a fixed axial length of 10 mm. Geometric optimization was carried out to determine the optimal aspect ratio of a unit cell of a heat sink that minimized the overall maximum temperature and thus maximized the overall global thermal conductance. The effect of total volume fraction of the silicon wafer on the optimal aspect ratio and minimized maximum temperature was also studied. Results show that as the pressure drop increases, the minimized peak temperature decreases, and suggests that there is an optimal allocation of solid volume fraction for a fixed pressure drop. The behaviour of the optimized volume is in agreement with the constructal design method, where the objective is to minimize the peak temperature, subject to the constraints of fixed total volume and solid (silicon wafer) material.
The quest for improved designs for the cooling of heat-generating devices has long been the goal of modern heat transfer engineers and researchers. In an era of rapid advances in the development of new high performance microchips and electronic miniaturization, the trend is to install an ever-increasing number of heat-generating devices into a given space. The ability to remove heat from these devices has become an important challenge in the design of these components.1 In coming years, it is projected that the heat fluxes from these devices may exceed 100 W/cm2 and air cooling techniques are unlikely to be able to meet the cooling needs of these high heat flux electronic packages,2,3 which is why there is great interest in micro-channel cooling techniques. This development has also led to an increasing demand for highly efficient cooling technologies. To solve these problems, several novel techniques have been proposed and studied theoretically, numerically and experimentally. These techniques have been reviewed by Dirker et al.1 One of the new ideas is in the field of constructal design,4 where objectives and global constraint (fixed volume, area, etc.), lead to a geometric form which performs maximally under given constraints. Designing an optimal configuration for micro-channels, where space and size are constrained, has become an area of particular interest as optimization of flow system architecture is a widespread occurrence in engineering and nature.
We will atttempt to explore this technique in the optimal design of a given micro-channel. The flow configuration/geometry is the unknown, and is free to change. According to constructal theory, the optimization of geometry starts at the smallest (elemental) scale, which in this study is a unit cell of a micro-channel heat sink with a fixed volume and variable shape. Optimal geometry has been determined for natural convection,5,6 and for forced convection with specified pressure differences.7,8 Most of these works have been reviewed in ref. 4 and are not reviewed again here.
Significant research916 has also been conducted on the flow and heat transfer characteristics of micro-channel heat sinks because of the ability to remove heat from high heat flux areas. These studies relied on the finite volume method to study the flow and heat transfer characteristics. They captured results that were also obtained experimentally,9,17 and proved the viability of the finite volume method in the modelling of flow and heat transfer in heat sinks or flow in small length scales.
The purpose of this paper is to optimize numerically the flow configuration of a micro-channel heat sink, by using the finite volume method. The volume of the heat sink cooling channel and the volume of the conducting solid material are fixed. Also fixed is the axial longitudinal pressure drop. We seek to determine the optimal geometry for maximum global conductance (or minimized peak temperature).
Model and mathematical formulation
Figure 1 shows a schematic drawing of the physical model and the computational domain for a micro-channel heat sink. Heat is supplied to the highly conductive silicon substrate with known thermal conductivity from a heating area located at the bottom of the heat sink; it is then removed by a fluid flowing through a number of micro-channels as shown in Fig. 1. Using the advantage of symmetry, we select for analysis a unit cell consisting of a micro-channel and the surrounding solids, as is shown in Fig. 2. This selection is based on the models of Tuckerman and Pease, and of Kawano et al. First we reproduced the work of Tuckerman and Pease, then applied constructal techniques to the design according to the work of Kawano et al.15
The heat transfer in the unit cell is a conjugate problem that combines heat conduction in the solid and convective heat transfer in the liquid. The two heat transfer mechanisms are coupled through the continuity of temperature and flux at the interface between the fluid and the solid. The fluid with inlet temperature T0 is driven through the micro-channel by a fixed pressure difference ΔP = P(z = 0) P(z = L), which is maintained between the channel inlet and outlet. The objective of the following analysis is to determine the heat transfer characteristics for a given micro-channel and the best possible configuration (L, t1/t2, t2/t3, H/G) which corresponds to the maximal global thermal conductance or global minimal thermal resistance.
The following assumptions were made to model the heat transfer and fluid flow in a unit cell under the conjugate model: the hydraulic diameter of the micro-channel under analysis is of the order of 100 µm; for water, the continuum regime applies hence the Navier-Stokes equation can still be used to describe the transport processes; steady-state conditions for flow and heat transfer; incompressible flow; the properties of the solid and fluid are constant; and the heat transfer due to radiation and natural convection are negligible. Based on these assumptions, the continuity, momentum and energy equations for the cooling fluid are
where ∇2 = ∂/∂x2 + ∂/∂y2 + ∂/∂z2, and the origin of the Cartesian frame (x, y, z) is located in the bottom left corner of the computational domain.
For the volume occupied by solid, the momentum equation is simply
and the energy equation is
The whole unit volume (cell) is treated as a unitary (continuous) domain. The geometric boundary conditions for the computational domains are indicated in Fig. 2. The flow boundary conditions are that no-slip occurs on the walls inside the channel. At the entrance of the channel, the pressure boundary conditions become
where Be is the dimensionless pressure number based on the unit volume.16,17 P = 1 atm at the channel outlet, and T = 20oC at the channel inlet. The thermal boundary condition consists of an assumed uniform heat flux that is imposed at the bottom of the heat sink
The remaining outside walls and the plane of symmetry of the heat sink were modelled as being adiabatic. The continuity of the temperature and flux at the interface of the solid and fluid surfaces requires
where n is the direction normal to the walls.
The shape of the heat sink and cooling channels are allowed to vary, by changing G, H, t1, t2 and t3. We are interested in the geometric arrangement that maximizes the overall global thermal conductance of the geometry, which in dimensionless form is defined as
Here q" is the heat flux from the base of the micro-channel heat sink, k is the thermal conductivity of the fluid, and L is the length of the computational domain of the unit volume. The global conductance C is a dimensionless way of expressing the ratio of the total heat transfer rate divided by the largest excess temperature (Tmax– T0) reached at any point in the heat sink. The reciprocal of C is defined as the dimensionless global thermal resistance.
Numerical method and code validation
The finite volume method was used to solve the continuity, momentum and energy equations. A detailed explanation is given in Patankar.19 In the finite volume method the domain is divided into a number of control volumes such that there is one control volume surrounding each grid point. The grid point is located in the centre of the control volume. The governing equation is integrated over each control volume to derive algebraic equations containing a point value of the dependent variable at the grid point. The discretized equations express the conservation principle for a finite volume.
The second-order upwind scheme was used to model the combined convection-diffusion effect in the transport equations. The resulting algebraic equations were solved using a line-by-line tri-diagonal matrix inversion algorithm. The SIMPLE algorithm18 was then applied to solve the coupled systems of equations. The solutions were considered converged with the criterion |(γi+1 γi+1)/γi+1|<103, where γ represents u, v, and w, and i is the iteration number. An additional convergence criterion was that the residual of the energy equation was less than 109. A grid independence study was carried out for the dimensions given in Table 1 to determine their maximum thermal resistance. Tests show that for a control volume a mesh size of 20 in the x-direction, 40 in the y-direction and 150 in the z-direction ensures a grid-independent solution in which the maximum thermal resistance changes less than 2.5% when the mesh is sequentially doubled.
The numerical code was verified in several ways. The first method was to reproduce the work of Tuckerman and Pease9 and Toh et al.14 (see Table 1). The computational model in Fig 2 was amended by removing the solid component on top of the heat sink and replacing it with a plastic cover and making t3 = 0. The results obtained using the finite volume method were then compared with experimentally measured thermal resistance from different flow rates. The results of this work were then compared with experimental results supplied by Tuckerman and Pease9 using the local thermal resistance,
In Equation (12) R(x) is the thermal resistance at some distance x from the entrance. Tables 1 show the values of the dimensions used to validate the present numerical model.
Table 2 reports the maximum thermal resistance for three cases tabulated in Table 1. These thermal resistances were reported at z = 9 mm. Table 2 shows the comparison between the thermal resistance measured experimentally by Tuckerman and Pease,9 numerically by Toh et al.,10 and those calculated [using Equation (12)] in this study. The agreement with the experimental work is within 28% for case 1, 11% for cases 2 and 3, and within 2% for the numerical results.
In the second validation of the numerical results, the heating component in Fig. 1 was placed on top of the micro-channel heat sink, as in the work of Qu and Mudawar.11 The comparison was made for different Reynolds numbers in the range of 90 < Re < 400, where the Reynolds number is defined as
and the hydraulic diameter is
where Ac is channel cross-sectional area and S is the perimeter of the micro-channel. Figure 3 reports the thermal resistance for inlet and outlet for the cases tabulated in Table 1b. It can be seen that the present numerical analyses also capture the work of Qu and Mudawar,11 and predicts well the inlet and outlet thermal resistances. The maximum differences are 1.8% for the inlet and 1.5% for the outlet resistances.
Once the model adopted in this work was validated, numerical optimization was performed to determine the optimal geometry of the micro-channel using the constraints outlined in the next section. The above code verification and grid-independent test provide confidence in the numerical code and approach used in this work. A detailed optimization procedure for the heat sink is presented in the following section.
Optimization constraints and parameters
The theory of constructal design is applied to an arbitrary unit of micro-channel heat sink with a fixed given volume (length and cross-sectional area), and substrate material. The only parameter that is allowed to vary is the cross-sectional shape of the heat sink, and the ratio of the internal thickness of the vertical and horizontal substrate.
The elemental volume constraint for a given computational cell is
and the volume of the solid substrate is
For a fixed length we have
The volume of the micro-channel is
Equation (16) can also be expressed in terms of the solid volume fraction, ø = Vs/V = As/A. Equations (16)(18) can be solved simultaneously for t1, t2 and t3 such that for any changes in the assumed thickness and geometric parameters, the aspect ratio (t1/t2, t2/t3, H/G and ø), the total volume, and volume of solid substrate remain fixed. Because the volume remains fixed, the cross-sectional shapes of the heat sink changes in such a way that the solid substrate conducts the heat from the base such that the thermal resistance is minimized. The total number of micro-channels in the heat sink is obtained by
for a fixed total width, W.
Results and discussion
A series of numerical optimizations and calculations has been conducted and the results are presented to show the effects of pressure drop, solid materials content, and effect of the external aspect ratio for a fixed set of internal aspect ratios (the ratio of base solid thickness to vertical thickness) on the optimal micro-channel geometry. Some important fluid flow and heat transfer parameters that are employed in this study are summarized in Table 1b. The thermo-physical properties of water used in this study are based on water at 20°C. The volume of the micro-channel is fixed and it is based on the data given by Qu and Mudawar.11 The applied heat flux at the bottom of the micro-channel was set at 100 W/cm2. We seek to determine the optimum geometry that minimizes the maximum temperature, Tmax, or the overall global conductance.
Optimal micro-channel heat sink
The heat sink has five degrees of freedom, L, H/G, t1/t2, t2/t3 and ø. For this study three degrees of freedom were fixed: L, t1/t2 and t2/t3, while the other two were allowed to vary with the assumed pressure drop. In the first stage of the optimization, we fixed the internal structure of the micro-channel by setting (t1/t2 = 0.08, t2/t3 = 1 and ø = 0.8). The total volume of the unit micro-channel was set to be V = 0.9 mm3, the axial length of the micro-channel was fixed at 10 mm, and the unit cross-sectional area was 0.09 mm2. The heat sink is expected to occupy a total base surface area of 10 mm × 10 mm. The pressure drop across a unit cell was set at 50 kPa for the first optimization. Figure 4 shows how the external shape H/G varies with Tmax (in all figures a marker is used for the result of the numerical study and a trend line is used to connect the markers). It shows that there exists an optimal micro-channel cross section that minimizes the maximum temperature at any point in the micro-channel arrangement. This procedure was repeated for different ranges of ø as shown in Fig. 5. This Figure suggests that there is an optimal allocation of solid fraction that minimizes the maximum temperatures.
Figure 6 summarizes the effects of pressure drop on the optimal external aspect ratio, in the range 10 kPa < ΔP < 75 kPa. For a fixed solid fraction, the optimal external aspect ratio exhibits two types of behaviour as shown in Fig. 6. At low pressure drop, the optimized ratio increases with a rise in the pressure drop, while for DP > 50 kPa, increased slightly with increase in the pressure drop and almost invariant for ø = 0.8. Similarly, the optimized external aspect ratio decreases with an increase in the solid volume fraction for the range of geometric parameters investigated in this study. As the aspect ratio increases, the channel becomes more slender in the vertical direction and the value of the hydraulic diameter changes. The optimal hydraulic diameter decreases with increase in the aspect ratio and with a rise in the pressure drop. The minimum optimal hydraulic diameter Dh,opt = 102 µm is obtained for a pressure drop of ΔP > 50kPa and ø = 0.8, whereas the maximum Dh,opt value of 154 µm corresponds to a pressure drop ΔP = 10 kPa and ø = 0.3. In this work, the optimal hydraulic diameter lies in the continuum region and gives us confidence in our continuum assumption.
Figure 7 describes the behaviour of the minimized maximum temperature difference, (ΔT)min, with respect to the applied pressure drop. (ΔT)min decreases monotonically with increase in pressure drop. There is an optimal volume of the solid fraction and lies in the vicinity of ø = 0.5 and 0.4. For the range of assumed parameters represented in in Fig. 7, the line represented by ø = 0.5 and 0.4 is located below the lines corresponding to ø = 0.3 and ø = 0.8.
Figure 8 shows another way of reporting the results obtained in Fig. 7. The results are reported based on the dimensionless global conductance [Equation (11)] and dimensionless pressure drop number, Be, from Equation (8). The maximized global thermal conductance increases with an increase in Be. Figure 8 suggests an optimal solid fraction exists in the vicinity of ø = 0.5 and 0.4. This should be investigated further in future research. For ø = 0.5, the maximized global thermal conductance can be correlated within 0.05% with the power law
These results are in agreement with previous work on the constructal method,4 according to which maximum heat transfer density means optimal packing such that flow regions that do not contribute to global performance are eliminated.
For practical design purposes, Table 3 reports the geometry and the numbers of micro-channels in a heat sink arrangement for a given optimial geometry. The total base area for the silicon wafer is fixed at 10 mm × 10 mm. Results show that, as the pressure drop increases, the number of channels also increases for a given solid volume fraction. These trends break down for high solid volume fraction (ø = 0.8) and pressure drop (ΔP > 50 kPa). These values can be used in future experimental set-ups to validate the numerical results.
Figure 9 shows the temperature distribution of an optimized micro-channel heat sink with a unit volume of 9 mm3 (ΔP = 50 kPa, = 8, ø = 0.8, t1/t2 = 0.08 and t2/t3 = 1). The figure illustrates the temperature distribution at the inlet plane through to the outlet of the micro-channel heat sink; note that the deep blue colour shown at the inlet of the micro-channels gradually changes to light blue for the axial location of z = 5 mm and to green at the outlet (z = 10 mm), as heat is conducted away from the bottom of the unit. This temperature distribution varies almost linearly from the inlet to the outlet of the micro-channels and is distributed optimally along the given volume, so that the maximum temperature at any given point in the heat sink geometry is minimized. The temperature is a maximum at the exit plane for any given geometry,
This paper addresses the fundamental problem of numerically optimizing a three-dimensional rectangular micro-channel heat sink by solving the three-dimensional conjugate heat transfer model, in which the micro-channel's hydraulic diameter is in the order of 100 µm, which is in the continuum region. The heat sink uses water as the cooling fluid, and consists of silicon wafer. The total volume of the heat sink is fixed, as is the axial length. In the first part of this paper, the numerical code is validated against known numerical and experimental results for micro-channels and was found to be in agreement with them. Numerical optimization results show that the optimal aspect ratio of a unit cell is a function of the imposed pressure drop and the solid volume fraction. The numerical results also indicate that there is an optimal solid volume fraction.
The main conclusion is that constructal optimization procedures need to be implemented to optimize the thermal and flow field design of the micro-channel heat sink, which will lead to the best external shape (aspect ratio) that minimizes (maximized global thermal conductance) the temperature difference between the cooling fluid and the maximum temperature at any point in the heat sink geometry.
We recommend that for future work both the external and internal aspect ratios (all the degrees of freedom) should be optimized simultaneously. Also, that the effects of thermal stresses on the optimized geometry at such a small length scale should be investigated. We expect that the conceptual design of micro-channel heat sinks using the constructal method will lead to the improved design of heat sinks, with superior performance and enhanced global thermal conductance.

text: The attackers who unleashed devastating hard-drive wiping malware on South Korean TV stations and banks earlier this week executed at least part of the attack by hijacking the firms' patch management admin accounts, the software vendor involved has said.According to South Korean antivirus company AhnLab, the 20 March attacks used stolen IDs and passwords for its Patch Manager software to distribute the malware to an unknown number of the 32,000 PCs affected inside the victim firms, including the Munhwa, YTN, Korea Broadcasting System (KBS) TV stations, and the Shinhan, Jeju and Nonghyup banks.These systems were under the control of the organisations involved and not AhnLab itself, the company emphasised."Contrary to early reports, no security hole in any AhnLab server or product was used by the attackers to deliver the malicious code," AhnLab said in a statement.The fact that several of the firms were using the company's software was coincidence; as a local ISV, AhnLab enjoyed a high market share in the country for its security products, the company said.Exactly how the attackers were able to get hold of the credentials and co-ordinate the attack remains a mystery but indicated that it had been planned for some time, AhnLab director of marketing and business development Brian Laing said.Some have suggested that the attackers had gained control of at least some of the target PCs using an undetected botnet system, but this remains speculation.Laing agreed that the attack had attempted to shut down AhnLab's antivirus client as well as that of a second popular South Korean vendor, Hauri.Claimed by the mysterious 'Whois' team, the attack attempted - and succeeded - in causing maximum disruption by overwriting the Master Boot Record (MBR) on affected PCs after a reboot.This is remarkably similar to the 'Shamoon' attack last year on Saudi Arabia's oil industry, which also affected about 30,000 systems after executing its disk-wiping routine at a pre-defined moment.One unusual element of the South Korean malware, dubbed 'Jokra' by Symantec, is that despite being Windows-oriented it contains a script that could be used to wipe Linux systems."The included module checks Windows 7 and Windows XP computers for an application called mRemote, an open source, multi-protocol remote connections manager," a Symantec analysis reported.Suspicions have fallen on North Korea or another state as the culprit simply because of the resources necessary to pull of such a targeted and highly-crafted attack.The fact that victims were solely South Korean has also reinforced this view. As with so many cyberattacks, evidence is and will probably remain, thin on the ground.

Like many young data-driven companies, BuildFax decided in 2008 to host its construction data services on Amazon Web Services. But now, it's moving some systems to Google's new IaaS (infrastructure-as-a-service) offering, some to other cloud providers and some to its first in-house servers.
BuildFax's vice president of research and development, Joe Emison, says he was at first delighted with Amazon's low costs and pay-as-you-go model. But he soon wanted a choice of public and private clouds so he'd have the flexibility to get the best price, performance and disaster recovery options as his needs changed -- and as computing technology and the capabilities of IaaS providers changed.
"You can take advantage of the benefits of the cloud without locking yourself down to Amazon" -- or any other provider, he says.
That viewpoint is slowly gaining traction as the IaaS business model grows beyond serving only smaller organizations and supporting less-critical systems such as development and testing. But becoming cloud-agnostic requires new tools and mindsets: Users must design applications that can survive the unpredictability of the cloud, and they have to ensure proper security.

In today's turbulent world, many people may wonder if the person with whom they work just might be the next psychopath to make news headlines.
According to the author of a new book, there are actually some professions that attract psychopaths more than others, and civil servants (including politicians), lawyers and TV and radio people are among those ranking very high.
Psychologist Kevin Dutton, author of "The Wisdom of Psychopaths: What Saints, Spies, and Serial Killers Can Teach Us About Success," has created a top 10 list for the most attractive and least attractive professions for psychopaths.
Advertisement - story continues below
The Journal of Abnormal Psychology notes that psychopathy is a personality disorder characterized by anti-social behavior, selfishness, egocentricity, callousness, manipulativeness and lack of empathy.
But in an interview with Smithsonian.com, Dutton said one of the reasons he wrote his book was to debunk two myths about psychopaths: that they're either all "mad or bad," and secondly, that psychopathy is an all-or-nothing thing, that you're either a psychopath or you're not.
TRENDING: What does God most care about?
"When psychologists talk about psychopaths, what we're referring to are people who have a distinct set of personality characteristics, which include things like ruthlessness, fearlessness, mental toughness, charm, persuasiveness and a lack of conscience and empathy. Imagine that you tick the box for all of those characteristics," Dutton explained.
"You also happen to be violent and stupid. It's not going to be long before you smack a bottle over someone's head in a bar and get locked up for a long time in prison. But if you tick the box for all of those characteristics, and you happen to be intelligent and not naturally violent, then it's a different story altogether. Then you're more likely to make a killing in the market rather than anywhere else."

Dutton claims the professions that seem to have the most psychopaths are:
1. Chief executive officer
2. Lawyer
3. Media (Television/Radio)
4. Salesperson
5. Surgeon
6. Journalist
7. Police officer
8. Clergy person
9. Chef
10. Civil servant
Dutton also lists the following professions as least attractive to psychopaths:
1. Care aide
2. Nurse
3. Therapist
4. Craftsperson
5. Beautician or stylist
6. Charity worker
7. Teacher
8. Creative artist
9. Doctor
10. Accountant


text: Despite several high-profile security breaches at major retailers, the government should let the private sector continue to set the rules for protecting credit- and debit-card data, a standards body says.[PCI DSS 3.0 is an evolution, not a revolution]Bob Russo, general manager for the Payment Card Industry (PCI) Security Standards Council, was scheduled to tell a congressional committee Wednesday that it's unlikely any government agency could duplicate "the expansive reach, expertise and decisiveness of PCI," referring to the standards set by the council."High profile events such as the recent breaches are a legitimate area of inquiry for the Congress, but should not serve as a justification to impose new government regulations," Russo said in an advance copy of his prepared remarks. "Any government standard in this area would likely be significantly less effective in addressing current threats, and less nimble in protecting consumers from future threats, than the constantly evolving PCI standards."Russo was one of several industry experts scheduled to testify before a subcommittee of the House Energy and Commerce Committee. Other congressional panels have been looking into the data breaches recently disclosed by Target, Neiman Marcus, Michaels Stores and more recently, White Lodging. The hotel management company warned Monday that the electronic cash registers in its restaurants and lounges on 14 of its properties might have been compromised during most of last year. The company manages hotel franchises under nationwide brand names such as Hilton, Marriott, Sheraton and Westin. The string of data breaches has drawn the attention of lawmakers who are asking the payment card industry, retailers and security experts to explain the processes used to protect consumers. On Monday, executives from Neiman Marcus and Target testified before the Senate Judiciary committee. The attackers who stole card data from Target and Neiman Marcus used malware that snatched the data from the memory of cash registers, called point-of-sale (POS) systems, before the information was encrypted.The latest version of the council's standards for POS systems require retailers to perform a default reset every 24 hours to remove any malware that could reside in memory, Russo said. [Major attacks on retailers cast spotlight on higher security cards]The council also supports deployment of smart cards that have an embedded chip, making it much more difficult for criminals to create counterfeit credit cards with stolen data. The so-called EMV chips are widely used in Europe, while in the U.S. the credit-card industry uses cards with less secure magnetic stripes.The use of smart cards would require expensive changes to hardware and software, so the retail, banking and credit card industries have been fighting for years over who will pay for the transition. However, credit card companies are starting to issue such cards when consumers ask for it.Russo pointed out that EMV chips, while useful for security, would not prevent the use of credit card numbers online. They also would not have prevented the recent data breaches."EMV chip technology could not have prevented the unauthorized access, introduction of malware, and subsequent exfiltration of cardholder data," he said.While government should stay out of setting standards, it could help deter payment card fraud through stronger law enforcement efforts worldwide. In addition, Congress could pass stiffer penalties for such crimes.Government could also simplify data breach notification laws and promote cyberattack information sharing between the public and private sectors."These are all opportunities for the government to help tackle this challenge," Russo said.

VICTORIA – An attempted terrorist attack using homemade bombs placed around the B.C. legislature was apparently an effort to do maximum damage as thousands gathered for Canada Day ceremonies, Premier Christy Clark said Tuesday.
"My suspicion is they wanted to do as much damage as they possibly could," Clark told reporters in front of the legislature. "They want to take control of our streets, our cities and and our institutions."
Clark said she heard about the plot to place pressure-cooker bombs on Monday, as police were monitoring the placement of devices they had already disabled. Police assured her there was never a threat to the 40,000 people who gathered in downtown Victoria for Canada Day concerts and fireworks.
As tourists filled the hallways of the legislature Tuesday, Clark said the intents of such attacks is to instil fear and anger in the public.
"We cannot let this change who we are," Clark said. "We will not let them win."
Surrey residents John Stewart Nuttall and Amanda Marie Korody were arrested in Abbotsford Monday afternoon in a surveillance operation co-ordinated by the RCMP, the Canadian Security Intelligence Service and the Canadian Border Services Agency.
Charges and dates indicate the pair were being observed as they prepared three pressure-cooker explosives similar to those used at the finish area of the Boston Marathon April 15.

Morning at the Souk

Djemaa El Fna
For those who haven't been there yet , the very center of the city is a square named Djemaa El Fna.
During the day it is predominantly occupied by orange juice stalls, youths with chained Barbary apes, water sellers in colourful costumes with traditional leather water-bags and brass cups, and snake charmers who will pose for photographs for tourists.[4]
As the day progresses, the entertainment on offer changes: the snake charmers depart, and late in the day the square becomes more crowded, with Chleuh dancing-boys (it would be against custom for girls to provide such entertainment), story-tellers (telling their tales in Berber or Arabic, to an audience of appreciative locals), magicians, and peddlers of traditional medicines. As darkness falls, the square fills with dozens of food-stalls as the number of people on the square peaks.
The square is edged along one side by the Marrakesh souk, a traditional North African market catering both for the common daily needs of the locals, and for the tourist trade. On other sides are hotels and gardens and cafe terraces offering an escape from the noise and confusion of the square.

BBC 3D radio is in the works
If you're like the majority of consumers, chances are even though you enjoy going out to the theater to see the occasional 3D movie, you really haven't seen any value in buying a 3D TV for your home. And even if you have one of the costly television sets, there's still a good chance you rarely or never actually watch 3D content at home. But that isn't stopping the BBC from moving into the 3D universe in a very different way.
The broadcaster is apparently working on a new technology for its radio broadcasts that it is referring to as "3D radio." The idea is that in the same way that 3D television and movies try to make you a part of the action, 3D radio aims to provide an immersing audio experience that makes it feel like the action is happening all around you. This would be most useful for things like concerts and sporting events.
BBC research and development lead technologist Frank Melchior said in an interview, "We want to deliver a new experience to the audience that gives them more immersion and involvement in the content. We also have to make sure we are flexible enough in the delivery of this content. It has to sound OK on headphones as well as on speakers." If successful, the BBC 3D radio project would not require listeners to buy new stereo equipment.

Still learning, Learning from Stills
"The proper drinking of Scotch whisky is more than indulgence: it is a toast to civilization, a tribute to the continuity of culture, a manifesto of man's determination to use the resources of nature to refresh mind and body and enjoy to the full the senses with which he has been endowed." - David Daiches, Scotch Whisky 1969
Still celebrating 100 Malt Missions (and giving the old liver a rest for a few days).
It has been an educational ride, and I thank you for reading and commenting, and hope you have learned some things, too.
i've learned that the internet is an incredible medium. i've learned that privilege is a small province. i've learned to distinguish between whisky lovers and whisky snobs. i've learned that a percentage of whisky buyers purchase whisky with more consideration for packaging than contents. i've learned that john glaser makes dull whisky dynamite with wood and johnnie walker with ice. i've learned that when corporations in the Dominion of Canada bought Scottish distilleries in the 1970s, they did them no favours. i've learned that price does not (necessarily) affect quality. i've learned that the travelling storyteller we met in Royal Mile Whiskies Edinbugh in 2006 was right, vanillin in the foods we eat and drinks we love is the breast calling out to all of us; the word 'vanilla', appears, in different shapes and sizes, in just under half of the Malt Missions, and in a few of them, more than once per post. i've learned what aldehydes, feints, esters, and phenols are. i've learned that whisky tastes better when you are hungry than when you are full. i've learned that i have much to learn.
Learning is fun.
I have noticed over the months that people search particular questions or terms that make it clear to me what information they are after, and I know that while I could help them with their inquiry, the information they are after just wont be found on my blog.
ex. "How old ledaig", "discontinue bowmore LCBO", "where to buy ________", "a long term effect of mixing a banana with a pineapple" (these are all real. more tomorrow)
Because of this I want to start a Dear Doctor-type of fuction.
Whisky Questions? what, how, why, when, etc.
Leave a comment or click through on my pic in the side column(left).
Happy Tuesday.

Good show Dr. Whisky!! Congratulations on your first 100. I really enjoyed your straight forward tasting notes and your willingness to taste anything and not let hype or price affect your opinion.
Time to queue up the next hundred, I'd say.
Keep 'em coming Sam! Been keeping up periodically over past few months. Good starting point when looking for something new.

Many presidents spoke in schools
Despite the crossfire from conservatives, the remarks President Barack Obama plans to deliver to America's pupils on Tuesday turn out to be in the mainstream of back-to-school remarks the previous four presidents delivered in classrooms.
The White House posted the president's prepared text on Monday, and it includes a variety of fatherly advice on persevering, finishing school and pursuing their dreams, plus his admonition that they're "no excuse for neglecting your homework or having a bad attitude … no excuse for talking back to your teacher, or cutting class, or dropping out of school … no excuse for not trying."
Dan Pfeiffer, White House deputy communications director, said: "As people can see from the text, this is a completely non-political speech that is in line with the tradition of presidents of both parties speaking directly to students about the importance of taking responsibility for their education."
It turns out that Obama's four most recent predecessors made remarks during fall visits to schools, many of them similar in tone and content to the script to be delivered at a high school in Arlington, Va., on Tuesday.
President Ronald Reagan told junior-high students they were living in a "time of unlimited possibilities, bounded only by the size of your imagination, the depth of your heart, and the character of your courage." President George H.W. Bush told another group of junior-high students: "I'm not here to tell you what to do or what to think. Maybe you're accustomed to adults talking about you and at you; well, today, I'm here to talk to you and challenge you. Education matters, and what you do today, and what you don't do can change your future."
President Bill Clinton said teachers need to give students a "high degree of self-awareness and an ability to learn and absorb and grow throughout a lifetime." And President George W. Bush used remarks at a magnet high school to reinforce his campaign message that "every student needs to be challenged."
Here are samples of what recent presidents have told returning students, as compiled by Democrats:
—President Reagan, "Q&A with Junior High School Students," Oct. 14, 1988: "America is not yet complete and it's up to each one of us to help complete it. And each one of you can place yourself in that painting. You can become one of those immortal figures by helping to build and renew America. And we're entering one of the most exciting times in history, a time of unlimited possibilities, bounded only by the size of your imagination, the depth of your heart, and the character of your courage. More than two centuries of American history, the contributions of the millions of people who have come before us have been given to us as our birthright. All we can do to earn what we've received is to dream large dreams, to live lives of kindness, and to keep faith with the unfinished vision of the greatness and wonder of America."
--President George H.W. Bush, "Remarks to Students and Faculty at Alice Deal Junior High School," Oct. 1, 1991: "Let me tell you why I've made the trip up from the White House to Alice Deal Junior High. I'm not here to teach a lesson. You already have a very good teacher. I'm not here to tell you what to do or what to think. Maybe you're accustomed to adults talking about you and at you; well, today, I'm here to talk to you and challenge you. Education matters, and what you do today, and what you don't do can change your future. … I ask every student watching today: Look around you. Count four students. Start with yourself. No one dreams of becoming a dropout, but far too many do. Which one of you won't make it through school? The fact is, every one of you can. Let's make a pact then right here. Let's work to see that 5 years from now, you and your friends will be more than sad statistics. Give yourself a decent shot at your dreams. Stay in school. Get that diploma … Make the connection between the homework you do tonight, the test you take tomorrow, and where you'll be 5, 15, even 50 years from now.
"You see, the real world doesn't begin somewhere else, some time way down there in the distant future. The real world starts right here. What you do here will have consequences for your whole lives. … When it comes to your own education, what I'm saying is take control. Don't say school is boring and blame it on your teachers. Make your teachers work hard. Tell them you want a first-class education. Tell them that you're here to learn. Block out the kids who think it's not cool to be smart. I can't understand for the life of me what's so great about being stupid. If someone goofs off today, are they cool? Are they still cool years from now when they're stuck in a dead-end job? Don't let peer pressure stand between you and your dreams. … Let me leave you with a simple message: Every time you walk through that classroom door, make it your mission to get a good education. Don't do it just because your parents, or even the President, tells you. Do it for yourselves. Do it for your future."
--President Clinton, "Remarks at Oak Bluffs [Mass.] School," Sept. 3, 1997: "You know, every start of a school year is special because, as you well know, teachers come together with a new sense of dedication and energy and students show up wide-eyed in anticipation and parents pour all their hopes into what they hope will come out of the next year, that they're all truly wonderful. And I think they reflect the central premise of what you do for a living, and that is that our most important common enterprise as a people is clearly education. It's necessary not only for young people to grow up and be able to earn a good living, but perhaps more importantly, to be good citizens and even beyond that to live their own lives to the fullest, with a high degree of self-awareness and an ability to learn and absorb and grow throughout a lifetime."
--President George W. Bush, "Remarks at Parkview Arts and Science Magnet High School," Aug. 29, 2002: "We've got to aim higher. We need to challenge every student. I don't mean just the top 10, I mean every student needs to be challenged. We've got to make sure that people understand, starting with the parents, by the way, that they ought to challenge their children to take the toughest classes possible. That's what we have to do. You get people up to the minimum, but that's not good enough. We've got to provide people to continue to challenge themselves."

Obama Calls Assassination Program A 'State Secret'
Justice Department officials took the controversial step yesterday of invoking the government's state secret privilege to try and dismiss a terrorism lawsuit over the "targeted killing" of a U.S. citizen.
Anwar al-Awlaki—the New Mexico-born Muslim cleric who's been linked to al-Qaeda, this spring's failed Times Square bombing, and the 2009 shooting at Fort Hood that left 13 people dead—was placed on the CIA's kill list in April.
In July, the ACLU and Center for Constitutional Rights filed a lawsuit to have al-Awlaki removed from the list. They sought an injunction to prevent the killing and an order for the government to disclose the standards under which American citizens are "targeted for death."
Now, the Obama administration is making a seemingly last-ditch effort to block the suit by invoking its state secret privilege, essentially shielding its actions from judicial review on the pretense of protecting national security.
The strategy is controversial not merely because it involves the government-sanctioned assassination of a U.S. citizen (!), but because of its stark ideological contrast to Obama's promises for increased government transparency and openness. (Incidentally, this isn't the first time the Obama administration has asserted the state secrets privilege — earlier this month, it used the same argument to successfully block a case involving a Bush era torture program.)
But if it's any comfort, Obama knows he's stepping in it. The Washington Post says DOJ officials decided to use the state secret argument "reluctantly," and they were "mindful" of the attacks critics levied against George W. Bush on similar issues.
Which doesn't exactly make "waging the fight against terrorism with excessive secrecy and unchecked claims of executive power" okay, exactly. But hey, at least they thought about it long and hard first.
