Faisan has the BEST RA's Stanford can find! From the dark horse Christina to the noble leader Eliza and every seaweed-eating Noah in between, this is a group of RA's unlike any other. Don't believe me? Subscribe to Christina's gif-filled email list and read all about Noah's seaweed adventures in Trevor's weekly housemeeting scribes, then you'll really understand what kind of chaos we're dealing with here.
Not only does Faisan have the most amazing group of RAs, but we also have two other equally amazing people who I like to dub the "basically other RAs." This is because they do many of the same things our RAs do, and play an equally important role in the residents' lives. These two people are fun-loving Caroline and Pun-loving Miguel--our RCC and SLERT! You won't find a group of people smiling more :)
The residents of Faisan include a wide range of people coming from all sorts of diverse backgrounds. Just to name a few, we have a resident poet, dinosaur, and spirit guide.. This is not to mention the many other slerds (that is, SLE nerds) that live amongst the chaos. Moreover, Faisan enjoys sharing the flove with its two upperclassmen ambassadors (or, the only upperclassmen that attend house meetings, speak to frosh, or say hi to anyone ever as I like to call them)--Daniel and Amy!


Posted on June 17, 2017
There’s a viral article today that the science is finally settled and left-handed people are smarter than right-handed people. There are good reasons to be skeptical. For those curious, the source paper can be found here. I’m not a neuroscientist so if I’m mistaken anywhere I would love to hear from you.
Any story that’s perfectly poised to make the internet do backflips deserves an extra ounce of skepticism. False positives tend to be over-represented in viral studies.
The justification for the finding was that hand function is
“a manifestation of brain function and is therefore related to cognition.”
This is so broad a statement as to be meaningless.  Is a manifestation of brain function necessarily related to cognition? Is cognition necessarily related to intelligence? We have a lot of bridges to build here.
While it is true that lefties have more connections between brain hemispheres, a property known as lateralization, there is actually no significant link between lateralization and brain function. This may seem counterintuitive, because labotomized patients lose 9.2 to 17 points of IQ. These facts together point to diminishing returns of lateralization beyond a certain threshold. Our default assumption should be that there’s no IQ benefit from the increased lateralization found in lefties, since we’re comparing against regular people not lobotomized patients.
Lefty children perform worse in math and “significantly worse in nearly all measures of development” when compared to righty children. Why should the effect direction reverse upon adulthood? The simplest answer is that one or both effects are spurious.
The authors fit a quartic polynomial linear regression with the only justification being its increased expressive power. But with great expressive power comes great responsibility. Try enough models, with enough complexity, and you’ll eventually find one that fits. That means, as we increase the complexity of our model, we’re increasing our chance of false positives.
I think economists do the best job here. Economists first build a mathematically intuitive, theoretical explanation of phenomena. That mathematical explanation hints at the proper form of the empirical model with which to test the theory. This is a robust scientific method where we first hypothesize, and then test once, as opposed to testing many times and forming a hypothesis from what works. The latter method is prone to overfitting and false positives. The former method is prone to underfitting. In my opinion a good scientist should heir on the side of underfitting, although Erika Salomon makes a great case that overfitting is worth the cost of false positives, because we also get more true positives.
I just wanted to point out some red statistical flags. I don’t mean to slander the authors of the original study, and I’ve not said anything to disprove their statements, but only to emphasize that we should be careful. If you’re a neuroscientists or someone with in-depth knowledge of the field, I’d be grateful for your setting me straight on anything above. Cheers guys :)

CRM-M-22159-2019 -1- 121 IN THE HIGH COURT OF PUNJAB AND HARYANA AT CHANDIGARH Date of decision-09.07.2019 1. CRM-M-22159-2019 M/S S.M.Industries and others ...Petitioners Vs. Haryana State Pollution Control Board ...Respondent 2. CRM-M-22207-2019 M/S Nirman Industries and others ...Petitioners Vs. Haryana State Pollution Control Board ...Respondent CORAM:- HON'BLE MR. JUSTICE MANOJ BAJAJ Present: Ms. Amrita Nagpal, Advocate for the petitioners. *** MANOJ BAJAJ, J. (Oral)
This judgment will dispose off the above mentioned two petitions i.e. CRM-M-22159-2019, titled as "M/S S.M.Industries and others Vs. Haryana State Pollution Control Board" and CRM-M-22207-2019, titled as "M/S Nirman Industries and others Vs. Haryana State Pollution Control Board". However, the facts are being extracted from CRM-M- 22159-2019.
Petitioners have filed this petition under Section 482 of Code of Criminal Procedure for quashing of criminal complaint No.2 of 2015 registered under Sections 37 and 38 of Air (Prevention and Control of Pollution) Act, 1981 (in short 'the Act') titled as "HSPCB Vs. M/s S.M Industries & Others" as well as the summoning order dated 28.01.2016 (Annexure P-2).
1 of 2 ::: Downloaded on - 20-10-2019 10:05:53 ::: CRM-M-22159-2019 -2- Learned counsel for the petitioners contends that the complaint as well as the summoning order are nothing but an abuse of process of law as the petitioners were under the impression that previously the unit which was operational at some other place, had the requisite consent by the competent authority and the same would be equally admissible at the present place where the unit was shifted. It is not disputed by learned counsel for the petitioners that the sample was drawn and the same had failed resulting into the proceedings under the Act.
At this stage, learned counsel for the petitioners has contended that subsequently, permission was also granted vide order dated 02.08.2016 (Annexure P-6) to run the unit at the existing place. The allegations in the complaint are based on documentary material and therefore, this Court finds that the summoning order is based on correct appreciation of the material on record. Further the subsequent permission granted by the competent authority was of no help, as the offence in the complaint pertains to the period for which there was no permission from the Pollution Control Board.
Learned counsel for the petitioners is unable to point out the stage of the complaint which was filed in the year 2015. It appears that the complaint must be at an advanced stage by now and therefore, this Court does not find any reason to interfere with the petition.
Resultantly, both petitions are dismissed.

| 1. We've already explored a two-dimensional version of the divergence theorem. | |
| 2. If I have some region-- so this is my region right over here. | |
| 3. We'll call it R. | |
| 4. And let's call the boundary of my region, let's call that C. | |
| 5. And if I have some vector field in this region, so let me draw a vector field like this. | |
| 6. If I draw a vector field just like that, our two-dimensional divergence theorem, which we really derived from Green's theorem, told us that the flux across our boundary of this region-- so let me write that out. | |
| 7. The flux across the boundary, so the flux is essentially going to be the vector field. | |
| 8. It's going to be our vector field F dotted with the normal outward-facing vector. | |
| 9. So the normal vector at any point is this outward-facing vector, So our vector field, dotted with the normal-facing vector at our boundary times our little chunk of the boundary. | |
| 10. If we were to sum them all up over the entire boundary-- let me write that a little bit neater-- that's the same thing as summing up over the entire region. | |
| 11. So let's sum up over the entire region. | |
| 12. So summing up over this entire region, each little chunk of area, dA-- we could call that dx dy if we wanted to if we're dealing in the xy domain right over here, but each little chunk of area times the divergence of F, which is really saying, how much is that vector field pulling apart? | |
| 13. So it's times the divergence of F. | |
| 14. And hopefully, it made intuitive sense. | |
| 15. The way that I drew this vector field right over here, you see everything's kind of coming out. | |
| 16. You could almost call this a source right here, where the vector field seems like it's popping out of there. | |
| 17. This has positive divergence right over here. | |
| 18. And so because of this, you actually see that the vector field at the boundary is actually going in the direction of the normal vector, pretty close to the direction of the normal vector, so it makes sense. | |
| 19. You have positive divergence, and this is going to be a positive value. | |
| 20. The vector field is going, for the most part, in the direction of the normal vector. | |
| 21. So the larger this is, the larger that is. | |
| 22. So hopefully, some intuitive sense. | |
| 23. If you had another vector field-- so let me draw another region-- that looked like this, so I could draw a couple situations. | |
| 24. So one where there's very limited divergence, maybe it's just a constant. | |
| 25. The vector field doesn't really change as you go in any given direction. | |
| 26. Over here you'll get positive fluxes. | |
| 27. I don't know what the plural of flux is. | |
| 28. You'll get positive fluxes, because the vector field seems to be going in roughly the same direction as our normal vector. | |
| 29. But here, you'll get a negative flux. | |
| 30. So stuff is coming in here. | |
| 31. If you imagine your vector field is essentially some type of mass density times volume, and we've thought about that before, this is showing how much stuff is coming in, and then stuff is coming out. | |
| 32. So your net flux will be close to zero. | |
| 33. Stuff is coming in, and stuff is coming out. | |
| 34. Here, you're just saying, hey, stuff is constantly coming out of this surface. | |
| 35.  Here you have a high divergence, and you would have a high aggregate flux. | |
| 37. I could draw another situation. | |
| 38. So this is my region R. | |
| 39. And let's say that we have negative divergence, or we could even call it convergence. | |
| 40. Convergence isn't an actual technical term, but you could imagine if the vector field is converging within R, well, the divergence is going to be negative in this situation. | |
| 41. It's actually converging, which is the opposite of diverging. | |
| 42. So the divergence is negative in this situation. | |
| 43. And also the flux across the boundary is going to be negative. | |
| 44. Because as we see here, the way I drew it, across most of this boundary, the vector field is going in the opposite direction. | |
| 45. It's going in the opposite direction as our normal vector at any point. | |
| 46. So hopefully, this gives you a sense of why there's this connection between the divergence over the region and the flux across the boundary. | |
| 47. Well, now we're just going to extend this to three dimensions, and it's the exact same reasoning. | |
| 48. If we have a-- and I'll define it a little bit more precisely in future videos-- a simple, solid region. | |
| 49. So let me just draw it. | |
| 50. And I'm going to try to draw it in three dimensions. | |
| 51. So let's say it looks something like that. | |
| 52. And one way to think about it is this is going to be a region that doesn't bend back on itself. | |
| 53. And if you have a region that bends back on itself-- well, we'll think about it in multiple ways. | |
| 54. But out of all the volumes of three dimensions that you can imagine, these are the ones that don't bend back on themselves. | |
| 55. And there are some that you might not be able to imagine that would also not make the case. | |
| 56. But even if you had ones that bent back on themselves, you could separate them out into other ones that don't. | |
| 57. So here is just a simple solid region over here. | |
| 58. I'll make it look three dimensional. | |
| 59. So maybe if it was transparent, you would see it like that. | |
| 60.  So it's this kind of elliptical, circular, blob-looking thing. | |
| 62. So that could be the back of it. | |
| 63. And then if you go to the front, it could look something like that. | |
| 64. So this is our simple solid region. | |
| 65. I'll call it-- well, I'll call it R still. | |
| 66. But we're dealing with a three dimensional. | |
| 67. We are now dealing with a three-dimensional region. | |
| 68. And now the boundary of this is no longer a line. | |
| 69. We're now in three dimensions. | |
| 70. The boundary is a surface. | |
| 71. So I'll call that S. | |
| 72. S is the boundary of R. | |
| 73. And now let's throw on a vector field here. | |
| 74. Now, this is a vector field in three dimensions. | |
| 75. And now let's imagine that we actually have positive divergence of our vector field within this region right over here. | |
| 76. So we have positive divergence. | |
| 77. So you can imagine that it's kind of-- the vector field within the region, it's a source of the vector field, or the vector field is diverging out. | |
| 78. That's just the case I drew right over here. | |
| 79. And the other thing we want to say about vector field S, it's oriented in a way that its normal vector is outward facing, so outward normal vector. | |
| 80. So the normal, it's oriented so that the surface-- the normal vector is like that. | |
| 81. The other option is that you have an inward-facing normal vector. | |
| 82. But we're assuming it's an outward-facing N. | |
| 83. Well, then we just extrapolate this to three dimensions. | |
| 84. We essentially say the flux across the surface. | |
| 85. So the flux across the surface, you would take your vector field, dot it with the normal vector at the surface, and then multiply that times a little chunk of surface, so multiply that times a little chunk of surface, and then sum it up along the whole surface, so sum it up. | |
| 86. So it's going to be a surface integral. | |
| 87. So this is flux across the surface. | |
| 88. It's going to be equal to-- if we were to sum up the divergence, if we were to sum up across the whole volume, so now if we're summing up things on every little chunk of volume over here in three dimensions, we're going to have to take integrals along each dimension. | |
| 89. So it's going to be a triple integral over the region of the divergence of F. | |
| 90. So we're going to say, how much is F? | |
| 91. What is the divergence at F at each point? | |
| 92. And then multiply it times the volume of that little chunk to sense of how much is it totally diverging in that volume. | |
| 93. And then you sum it up. | |
| 94. That should be equal to the flux. | |
| 95. It's completely analogous to what's here. | |
| 96. Here we had a flux across the line. | |
| 97. We had essentially a two-dimensional-- or I guess we could say it's a one-dimensional boundary, so flux across the curve. | |
| 98. And here we have the flux across a surface. | |
| 99. Here we were summing the divergence in the region. | |
| 100. Here we're summing it in the volume. | |
| 101. But it's the exact same logic. | |
| 102. If you had a vector field like this that was fairly constant going through the surface, on one side you would have a negative flux. | |
| 103. On the other side, you would have a positive flux, and they would roughly cancel out. | |
| 104. And that makes sense, because there would be no diverging going on. | |
| 105. If you had a converging vector field, where it's coming in, the flux would be negative, because it's going in the opposite direction of the normal vector. | |
| 106. And so the divergence would be negative as well, because essentially the vector field would be converging. | |
| 107. So hopefully this gives you an intuition of what the divergence theorem is actually saying something very, very, very, very-- almost common sense or intuitive. | |
| 108. And now in the next few videos, we can do some worked examples, just so you feel comfortable computing or manipulating these integrals. | |
| 109. And then we'll do a couple of proof videos, where we actually prove the divergence theorem. |

Orbit Maintenance Model
This section explains the algorithm behind the fast but approximated orbit maintenance simulations (“Sam’s Simulator”).
The key idea is that one does not need to obtain all six parameters of the spacecraft during orbit propagation! Where a sufficiently accurate drag model is available, one really just needs the radial magnitude of the spacecraft in order to characterise the orbital energy loss due to the atmospheric density. This simplifies the number of calculations needed. In this section, the derivation of the decay model will be shared.
The goal of this exercise is to derive how the rate of change of a satellite’s radial distance relates to the drag forces at play. We begin with first principles - an expression on the orbit state energy - and find its derivative with respect to time and altitude.
The rate of change of work done by drag forces can be multiplied with the inverse of the altitude derivative of orbital energy, thereby removing the energy differential, dU, as the common term. Now, we have an expression for the rate of altitude change! We simply need to input the drag force F, and the radial distance of the satellite R.
The radial distance R can be solved for through Kepler’s Equation in the Python file orbitm_func_kepler.py and using the input orbit parameters for a purely Keplerian orbit.
The drag force F, or equivalently the drag acceleration α, is computed via the standard drag equation, as a result of the satellite area-to-mass parameters (as set by the user), and the atmopsheric density value at radial distance R. The density is sourced from orbitm_func_atmos.py. This file is basically the U.S. Standard Atmosphere 1976, represented as a look-up table of coefficients for an exponential atmospheric model.
Simplifying the altitude decay rate model, we arrive at the elegant statement in 4.3:
This is powerful, because it proves that the rate at which the orbit decays can be solved in closed-form without any full orbit propagation of orbit states! This is the reason why orbit maintenance computations are extremely fast on ORBITM.
As the decay rate is also small, the total decay appears almost linear within the time frame of a single LEO orbital period (~95 minutes). Thus, a larger step size can also be used, without compromising too much on accuracy.
Consequently, the ORBITM program simply loops through the scenario time, and computes the decay in each time step until the spacecraft descends below the Maintenance Tolerance Band, which then triggers an orbit raise. This repeats until the end of the simulation.

Introduction
To catch and send crashes that occur while the app is starting up, the app has to get adjusted a little bit to make this work.
The challenges in this scenario are:
- Sending crash reports needs to be asynchronous, otherwise it would block the main thread or bad network conditions could make it even worse
- If the startup takes too long or the main thread is blocking too long, the watchdog process will kill the app
- The app might crash again before the crash report could have been send
HowTo
- Setup the SDK
- Check if the app crashed in the last session by checking
[BITCrashManager didCrashInLastSession]
- Check if
[BITCrashManager timeintervalCrashInLastSessionOccured]
is below a treshhold that you define. E.g. say your app usually requires 2 seconds for startup, and giving sending a crash report some time, you mighe choose5
seconds as the treshhold - If the crash happened in that timeframe, delay your app initialization and show an intermediate screen
- Implement the
BITCrashManagerDelegate
protocol methods- (void)crashManagerWillCancelSendingCrashReport:(
BITCrashManager*)crashManager
,- (void)crashManager:(
BITCrashManager*)crashManager didFailWithError:(NSError *)error;
and- (void)crashManagerDidFinishSendingCrashReport:(
BITCrashManager*)crashManager;
and continue app initialization
Example
@interface BITAppDelegate () BITCrashManagerDelegate {}
@end
@implementation BITAppDelegate
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
[self.window makeKeyAndVisible];
[[BITHockeyManager sharedHockeyManager] configureWithIdentifier:@"<>"
delegate:nil];
// optionally enable logging to get more information about states.
[BITHockeyManager sharedHockeyManager].debugLogEnabled = YES;
[[BITHockeyManager sharedHockeyManager] startManager];
if ([self didCrashInLastSessionOnStartup]) {
// show intermediate UI
} else {
[self setupApplication];
}
return YES;
}
- (BOOL)didCrashInLastSessionOnStartup {
return ([[BITHockeyManager sharedHockeyManager].crashManager didCrashInLastSession] &&
[[BITHockeyManager sharedHockeyManager].crashManager timeintervalCrashInLastSessionOccured] < 5);
}
- (void)setupApplication {
// setup your app specific code
}
#pragma mark - BITCrashManagerDelegate
- (void)crashManagerWillCancelSendingCrashReport:(BITCrashManager *)crashManager {
if ([self didCrashInLastSessionOnStartup]) {
[self setupApplication];
}
}
- (void)crashManager:(BITCrashManager *)crashManager didFailWithError:(NSError *)error {
if ([self didCrashInLastSessionOnStartup]) {
[self setupApplication];
}
}
- (void)crashManagerDidFinishSendingCrashReport:(BITCrashManager *)crashManager {
if ([self didCrashInLastSessionOnStartup]) {

Now for six whole weeks they went sailing on and on, over the rolling sea, following the swallow who flew before the ship to show them the way. At night she carried a tiny lantern, so they should not miss her in the dark; and the people on the other ships that passed said that the light must be a shooting star.
As they sailed further and further into the South, it got warmer and warmer. Polynesia, Chee–Chee and the crocodile enjoyed the hot sun no end. They ran about laughing and looking over the side of the ship to see if they could see Africa yet.
But the pig and the dog and the owl, Too–Too, could do nothing in such weather, but sat at the end of the ship in the shade of a big barrel, with their tongues hanging out, drinking lemonade.
Dab–Dab, the duck, used to keep herself cool by jumping into the sea and swimming behind the ship. And every once in a while, when the top of her head got too hot, she would dive under the ship and come up on the other side. In this way, too, she used to catch herrings on Tuesdays and Fridays—when everybody on the boat ate fish to make the beef last longer.
When they got near to the Equator they saw some flying–fishes coming towards them. And the fishes asked the parrot if this was Doctor Dolittle's ship. When she told them it was, they said they were glad, because the monkeys in Africa were getting worried that he would never come. Polynesia asked them how many miles they had yet to go; and the flying–fishes said it was only fifty–five miles now to the coast of Africa.
And another time a whole school of porpoises came dancing through the waves; and they too asked Polynesia if this was the ship of the famous doctor. And when they heard that it was, they asked the parrot if the Doctor wanted anything for his journey.
And Polynesia said, "Yes. We have run short of onions."
"There is an island not far from here," said the porpoises, "where the wild onions grow tall and strong. Keep straight on—we will get some and catch up to you."
So the porpoises dashed away through the sea. And very soon the parrot saw them again, coming up behind, dragging the onions through the waves in big nets made of seaweed.
The next evening, as the sun was going down the Doctor said,
"Get me the telescope, Chee–Chee. Our journey is nearly ended. Very soon we should be able to see the shores of Africa."
And about half an hour later, sure enough, they thought they could see something in front that might be land. But it began to get darker and darker and they couldn't be sure. Then a great storm came up, with thunder and lightning. The wind howled; the rain came down in torrents; and the waves got so high they splashed right over the boat.
Presently there was a big BANG! The ship stopped and rolled over on its side.
"What's happened?" asked the Doctor, coming up from downstairs.
"I'm not sure," said the parrot; "but I think we're ship–wrecked. Tell the duck to get out and see."
So Dab–Dab dived right down under the waves. And when she came up she said they had struck a rock; there was a big hole in the bottom of the ship; the water was coming in; and they were sinking fast.
"We must have run into Africa," said the Doctor. "Dear me, dear me!—Well—we must all swim to land."
But Chee–Chee and Gub–Gub did not know how to swim.
"Get the rope!" said Polynesia. "I told you it would come in handy. Where's that duck? Come here, Dab–Dab. Take this end of the rope, fly to the shore and tie it on to a palm–tree; and we'll hold the other end on the ship here. Then those that can't swim must climb along the rope till they reach the land. That's what you call a 'life–line.'"
So they all got safely to the shore—some swimming, some flying; and those that climbed along the rope brought the Doctor's trunk and handbag with them.
But the ship was no good any more—with the big hole in the bottom; and presently the rough sea beat it to pieces on the rocks and the timbers floated away.
Then they all took shelter in a nice dry cave they found, high up in the cliffs, till the storm was over.
When the sun came out next morning they went down to the sandy beach to dry themselves.
"Dear old Africa!" sighed Polynesia. "It's good to get back. Just think—it'll be a hundred and sixty–nine years to–morrow since I was here! And it hasn't changed a bit! Same old palm–trees; same old red earth; same old black ants! There's no place like home!"
And the others noticed she had tears in her eyes—she was so pleased to see her country once again.
Then the Doctor missed his high hat; for it had been blown into the sea during the storm. So Dab–Dab went out to look for it. And presently she saw it, a long way off, floating on the water like a toy–boat.
When she flew down to get it, she found one of the white mice, very frightened, sitting inside it.
"What are you doing here?" asked the duck. "You were told to stay behind in Puddleby."
"I didn't want to be left behind," said the mouse. "I wanted to see what Africa was like—I have relatives there. So I hid in the baggage and was brought on to the ship with the hard–tack. When the ship sank I was terribly frightened—because I cannot swim far. I swam as long as I could, but I soon got all exhausted and thought I was going to sink. And then, just at that moment, the old man's hat came floating by; and I got into it because I did not want to be drowned."
So the duck took up the hat with the mouse in it and brought it to the Doctor on the shore. And they all gathered round to have a look.
"That's what you call a 'stowaway,'" said the parrot.
Presently, when they were looking for a place in the trunk where the white mouse could travel comfortably, the monkey, Chee–Chee, suddenly said,
"Sh! I hear footsteps in the jungle!"
They all stopped talking and listened. And soon a black man came down out of the woods and asked them what they were doing there.
"My name is John Dolittle—M. D.," said the Doctor. "I have been asked to come to Africa to cure the monkeys who are sick."
"You must all come before the King," said the black man.
"What king?" asked the Doctor, who didn't want to waste any time.
"The King of the Jolliginki," the man answered. "All these lands belong to him; and all strangers must be brought before him. Follow me."
So they gathered up their baggage and went off, following the man through the jungle.


[gecode-users] consistency level for relations in MiniModel
Kish Shen
kisshen at cisco.com
Wed Mar 23 22:14:12 CET 2011
Hi,
I am now looking at updating the ECLiPSe's gecode interface to the
latest version of gecode.
I have been using gecode 3.3 for the ECLiPSe interface because I have
been using the old facilities for LinRel and LinExpr, by breaking down
user's expression (which may be non-linear) into subexpressions and
posting them. It looks like this can now all be done by using the
relation facilities of MiniModel, so I do not need to break the
expressions down myself.
However, I am not very clear if I can specify the consistency level for
relations and expressions I post using expr() and rel() of MiniModel. In
my current code, where linear relations are posted using post, I am able
to specify the consistency level. This allowed me to let the user (at
the ECLiPSe level) to specify a consistency level for their (possibly
non-linear) expressions and relations, with the understanding that the
consistency level might not be achieved for parts of the expression
(e.g. the non-linear parts).
I have been looking at the current Modelling and Programming with
Gecode, in particular the MiniModel chapter, and it is not clear to me
that you can specify a consistency level for rel (and expr). Can the
consistency level be specified?
On a related point, the MiniModel chapter show example of specifying the
expressions and relations directly in C++. In my code, I will be
translating user specified relations/expressions to gecode data
structures. In the existing code, LinExpr and LinRel are constructed
in my C++ code, and I will need to be able to do the same thing with
IntExpr. I cannot find IntExpr in the (web-based) Gecode Reference
Documentation, probably because I don't know where to look. I looked in
the "Direct modelling support" page in the Programming models section,
but I found only the linear relations and expressions that I am already
using.
I guess my first question (about consistency level) is also because I
don't know which section in the reference documentation to look up the
rel/expr facilities described in the MiniModel chapter.
Thanks in advance for any help and information!
Cheers,
Kish

LSU, Ohio State, Clemson, Georgia remain atop CFP rankings
by RALPH D. RUSSOThe College Football Playoff rankings were unchanged at the top this week, with LSU first followed by Ohio State, Clemson and Georgia.
The selection committee’s third weekly rankings had little movement in the top 10, with Alabama fifth followed by Oregon, Utah, Penn State, Oklahoma and Minnesota.
The committee could face an interesting decision with Alabama in the coming weeks. The Crimson Tide lost quarterback Tua Tagovailoa for the season to a hip injury Saturday. Alabama faces Western Carolina this weekend, so playing backup Mac Jones shouldn’t make much difference. On Thanksgiving weekend, the Tide will face Auburn with its No. 2 quarterback, which should give the committee a better read on what kind of a team Alabama is now.
Minnesota and Baylor, both of which lost for the first time last weekend, dropped in the rankings. Minnesota went from eighth to 10th after losing at Iowa. Baylor slipped from 13th to 14th after blowing a 25-point lead to Oklahoma.
Ohio State and Penn State play this weekend in a game that could essentially eliminate the Nittany Lions from the playoff race.
The highest ranked team from outside the Power Five conferences is Memphis at 18th, one ahead of American Athletic Conference rival Cincinnati, and two ahead of Boise State from the Mountain West.

The two residential skyscrapers, built by the edge of the once unpopular Isola neighborhood, look very much like huge green Jenga towers. Each floor is adorned by large irregular balconies that host more than 900 trees and 14 thousand plants. Integrating all of this lush green into a luxurious apartment complex has an endless list of benefits for the lucky ones who can afford to live there. Trees filter the light during the summer and let it in in the winter, act as a shield from wind, absorb fine dusts, release oxygen and humidity.

Configuration Management
In this exercise we are going to extend the Java API of the workshop sample such as that it uses a bunch of environment variables, and allow for different secrets configuration in development versus production environments.
The project folder for this exercise is ~/ddev-labs/configuration-management
.
Planning Environment-Specific API Config
Creating a Release Image
In this part of this exercise, we'll start by creating a release image like shown in following figure:
/
Have a look in
api/Dockerfile
; the final image is based off ofjava:8-jdk-alpine
. This java base image corresponds to the application base image, likely provided to us by our operations team. We expect any company-wide general config to have already been captured there.Build the API image as is:
ubuntu@infra:~$ cd ~/ddev-labs/configuration-management/api ubuntu@infra:~/ddev-labs/configuration-management/api$ docker image build \ -t api:release .
This corresponds to our release image - it has our application on top of our enterprise base image, but no environment-specific config has been included yet.
Creating an Environment Image for Development
Including Config in the Environment Image
In this part of the exercise, we will start by including a postgres password into an environment image like shown in the following figure:
/
Have a look in
api/src/main/java/com/docker/ddev/configuration/JpaConfiguration.java
. There should be a block that begins:// Set password to connect to postgres using Docker secrets. try(BufferedReader br = new BufferedReader(new FileReader("/run/secrets/postgres_password"))) { ...
Our API relies on a secret to be able to access our Postgres database. As discussed in the secrets section, it may be convenient to mock the presence of this secret in development, in case we aren't running Swarm mode on our dev machines.
Make a development environment image for your API that mocks the presence of a secret in its nominal location by copying the file with your postgres password into the
api
folder:ubuntu@infra:~/ddev-labs/configuration-management/api$ cp \ ../devsecrets/postgres_password .
And create a Dockerfile called
Dockerfile-dev
that places this file where it would if it was a Swarm-managed secret, in an image based on your release image:FROM api:release ADD postgres_password /run/secrets/postgres_password
Another option in this situation would be to use the same image for development and production, but mount a secret file into
/run/secrets/postgres_password
at runtime to mock the secret in the dev image. This has the advantage of only creating one image for both environments, but the disadvantage that that config (mounting the volume) has to be repeated each time the application is run in the dev environment. The approach followed in this step pushes that config as far 'upstream' as possible, to avoid repetition later, at the cost of image flexibility.Build this development environment image:
ubuntu@infra:~/ddev-labs/configuration-management/api$ docker image build \ -f Dockerfile-dev \ -t api:dev .
Passing Config On Startup
In the following, we will pass further needed configuration in a file as shown in this figure:
/
Open the class
TestController.java
in the folderapi/src/main/java/com/docker/ddev/controller
. In this class we have ashowConfig
method that listens on the endpoint/utility/showConfig
and returns the content of some environment variables:... public ResponseEntity<?> showConfig() { logger.info("Performing showConfig"); JSONObject config = new JSONObject(); config.put("APP_ENVIRONMENT", System.getenv("APP_ENVIRONMENT")); config.put("IMAGES_DIRECTORY", System.getenv("IMAGES_DIRECTORY")); config.put("PDF_DIRECTORY", System.getenv("PDF_DIRECTORY")); config.put("MIN_STOCK_COUNT", System.getenv("MIN_STOCK_COUNT")); return new ResponseEntity<JSONObject>(config, HttpStatus.OK); } ...
We'd like to control these variables dynamically at startup.
To the file
configuration-management/env-dev.conf
add the following definitions:APP_ENVIRONMENT=DEV IMAGES_DIRECTORY=/some/folder/for/dev/images PDF_DIRECTORY=/some/folder/for/dev/pdf MIN_STOCK_COUNT=2
Copy the file
configuration-management/docker-compose.yml
to a new filedocker-compose-dev.yml
.Open the file
docker-compose-dev.yml
and add the following to theapi
service:under
build
, adockerfile
line pointing atDockerfile-dev
.and an
env_file
section with the fileenv-dev.conf
.
After the changes, the
api
service should look as follows:... api: build: context: api dockerfile: Dockerfile-dev image: ddev_api ports: - "8080:8080" - "5005:5005" networks: - front-tier - back-tier env_file: - env-dev.conf ...
Run the application with the configuration file:
ubuntu@infra:~/ddev-labs/configuration-management$ docker-compose \ -f docker-compose-dev.yml up -d --build
Test the configuration:
ubuntu@infra:~$ curl localhost:8080/api/show-config | jq
and you should see something like this:
{ "PDF_DIRECTORY":"/some/folder/for/dev/images", "IMAGES_DIRECTORY":"/some/folder/for/dev/pdf", "APP_ENVIRONMENT":"DEV", "MIN_STOCK_COUNT":"2" }
At this point, we have defined a hierarchy of images, from application base image, to release image, to development environment image that capture increasing levels of specificity at each tier. Also, we have successfully captured the environment variables for our developer environment in a configuration file referenced by a compose file dynamically at startup.
Tear down the app:
ubuntu@infra:~/ddev-labs/configuration-management$ docker-compose \ -f docker-compose-dev.yml down
Preparing Deployment to Production
Next, let's take advantage of the hierarchy we've set up to quickly and easily prepare to deploy to a production environment.
In production, we want to use a real secret, not the mock in our
api:dev
image. In this case, there's no special config we need to insert into the image, since Docker's secrets functionality will do this for us. Simply retag our release image:ubuntu@infra:~$ docker image tag api:release api:prod
We'll see later how Docker Enterprise Edition can do such 'image promotion' for us as part of an automated CI/CD chain, in order to automatically perform such a retagging.
Start up swarm mode if you haven't already, to use as our 'production environment', and then create a secret for use by our production app:
ubuntu@infra:~$ docker swarm init ubuntu@infra:~$ echo "gordonpass" | docker secret create postgres_password -
Define a new environment variable file
env-prod.conf
in the folderconfiguration-management
:APP_ENVIRONMENT=PROD IMAGES_DIRECTORY=/some/folder/for/production/images PDF_DIRECTORY=/some/folder/for/production/pdf MIN_STOCK_COUNT=5
Create a file
docker-compose-prod.yml
based on the existingdocker-compose.yml
that uses your newapi:prod
image, provisioning it with the secret and production environment-specific config file you just created.Here is how
docker-compose-prod.yml
could look like:version: "3.1" services: database: build: context: database image: ddev_db environment: POSTGRES_USER: gordonuser POSTGRES_DB: ddev ports: - "5432:5432" networks: - back-tier api: image: api:prod ports: - "8080:8080" - "5005:5005" networks: - front-tier - back-tier secrets: - postgres_password env_file: - env-prod.conf ui: build: context: ui image: ddev_ui ports: - "3000:3000" networks: - front-tier networks: front-tier: back-tier: secrets: postgres_password: external: true
Run the production version:
ubuntu@infra:~/ddev-labs/configuration-management$ docker stack deploy \ -c docker-compose-prod.yml prod
Test the production version of your application to make sure it works as expected:
ubuntu@infra:~$ curl localhost:8080/api/show-config | jq
Clean up:
ubuntu@infra:~/ddev-labs/configuration-management$ docker stack rm prod ; \ docker swarm leave -f
Configuration Management in Kubernetes
We have already seen how secrets are handled in Kubernetes. Let's now see how we can use ConfigMap objects to configure our application.
In
kube.yaml
, notice the definition of aConfigMap
object:apiVersion: v1 kind: ConfigMap metadata: name: dev-config namespace: ddev data: APP_ENVIRONMENT: DEV APP_IMAGES_DIRECTORY: "/some/folder/for/dev/images" APP_PDF_DIRECTORY: "/some/folder/for/dev/pdf" APP_MIN_STOCK_COUNT: "2"
We import this into a pod by name in the same file:
envFrom: - configMapRef: name: dev-config
Create the objects in Minikube:
ubuntu@infra:~/ddev-labs/configuration-management$ kubectl apply -f kube.yaml
Note that the container will run in the pod executing this command:
/bin/sh -c "env"
which will output the list of all environment variables as seen by the container.Now get the (sorted) log from the the container we just ran:
ubuntu@infra:~/ddev-labs/configuration-management$ kubectl -n ddev \ logs po/config-test-pod | sort
it should look similar to this:
APP_ENVIRONMENT=DEV APP_IMAGES_DIRECTORY=/some/folder/for/dev/images APP_MIN_STOCK_COUNT=2 APP_PDF_DIRECTORY=/some/folder/for/dev/pdf HOME=/root HOSTNAME=config-test-pod KUBERNETES_PORT=tcp://<IP_ADDRESS>:443 KUBERNETES_PORT_443_TCP=tcp://<IP_ADDRESS>:443 ...
as you can see, the
envFrom
key in ourkube.yaml
points to batches of environment variables to be defined in a running container, as defined byConfigMap
objects.Clean up:
ubuntu@infra:~/ddev-labs/configuration-management$ kubectl delete ns/ddev
Optional Challenge: Packaging and Shipping
Now that we've created two versions of our application for two different environments, let's package it up so we can deploy it easily on a remote datacenter.
Create a git repo with two branches
dev
andprod
, put the appropriate versions of your app in each, and push to GitHub.Tag all the images your datacenter will need to pull appropriately, and push them to Docker Hub.
Log into your first AWS node (
ucp-manager
), and pull your project from GitHub.Stand up your application configured for the dev environment.

Conclusion
In this exercise, we defined a simple hierarchy of images and config files that capture configuration at a few different steps. As a rule of thumb, configuration should live at the most general level of this hierarchy that makes sense. For example, it wouldn't make sense to mock your secret in your upstream release image, since the production image will mount a real secret instead. However, it's not necessary to put off mocking that secret to startup or runtime for your developer environment, so the correct place to mock that secret was in the developer environment image.
By the same token, we left environment variables out of our images and defined them at startup in env.conf
files in Swarm or via ConfigMap
objects in Kubernetes, to maintain flexibility in their definition as long as possible. We could go a step further and push config definition all the way to runtime, by providing our containers with whatever information they need to query outside services (Hashicorp vaults, Consul KV stores...) dynamically while running.
