This document is adapted from Code for America’s Code of Conduct and Anti-Harrassment Policy.
The Code for San Jose community expects that Code for San Jose network activities, events, and digital forums:
Code for San Jose reserves the right to ask anyone in violation of these policies not to participate in Code for America network activities, events, and digital forums.
This anti-harassment policy is based on the example policy from the Geek Feminism wiki, created by the Ada Initiative and other volunteers.
This policy is based on several other policies, including the Ohio LinuxFest anti-harassment policy, written by Esther Filderman and Beth Lynn Eicher, and the Con Anti-Harassment Project. Mary Gardiner, Valerie Aurora, Sarah Smith, and Donna Benjamin generalized the policies and added supporting material. Many members of LinuxChix, Geek Feminism and other groups contributed to this work.
All Code for San Jose network activities, events, and digital forums and their staff, presenters, and participants are held to an anti-harassment policy, included below.
In addition to governing our own events by this policy, Code for San Jose will only lend our brand and fund groups that offer an anti-harassment policy to their attendees. For information on how to offer an anti-harassment policy to your group, see this guide from Code for America.
Code for San Jose is dedicated to providing a harassment-free experience for everyone regardless of gender, gender identity and expression, sexual orientation, disability, physical appearance, body size, race, age, or religion. We do not tolerate harassment of staff, presenters, and participants in any form. Sexual language and imagery is not appropriate for any Code for America event or network activity, including talks. Anyone in violation of these policies may expelled from Code for America network activities, events, and digital forums, at the discretion of the event organizer or forum administrator.

If a participant engages in harassing behavior, the organizers may take any action they deem appropriate, including warning the offender or expulsion from Code for San Jose network activities, events, and digital forums.
If you are being harassed, notice that someone else is being harassed, or have any other concerns, please contact Code for San Jose Captains Michelle Thong and Vivek Bansal.
Event staff or forum administrators will be happy to help participants contact hotel/venue security or local law enforcement, provide escorts, or otherwise assist those experiencing harassment to feel safe for the duration of the event.
If you cannot reach an event organizer or forum administrator and/or it is an emergency, please call 911 and/or remove yourself from the situation.
You can also contact Code for America about harassment at<EMAIL_ADDRESS>and feel free to use the email template below. Code for America staff acknowledge that we are not always in a position to evaluate a given situation due to the number of events and the fact that our team is not always present. However, we are hopeful that by providing these guidelines we are establishing a community that jointly adheres to these values and can provide an environment that is welcoming to all.
We value your attendance and hope that by communicating these expectations widely we can all enjoy a harassment-free environment.

DIABOLIQUE A film review by Michael John Legeros Copyright 1996 Michael John Legeros
(WB) Directed by Jeremiah Chechik Written by Don Roos Cast Sharon Stone, Isabelle Adjani, Chazz Palminteri, Kathy Bates MPAA Rating "R" (presumably for language, violence, nudity, etc.) Running Time 107 minutes Reviewed at General Cinemas at Pleasant Valley, Raleigh, NC (24MAR96)
==
Woof! DIABOLIQUE reminds me of those activity-book pages that I used to love-- the ones titled "what's wrong with this picture?" So many problems surface in this failed French-film remake that it's difficult to know where to start! The tone is the worst-- an overly oppressive mood that lands with an almost-audible thud.  Try this for dialogue: "If it's all the same to you, I'd rather not hang for fried chicken." No, not as good-bad as SHOWGIRLS, but close. Very close. The defining moment comes at the end, when Stone and Adjani are finishing some business in the shallow end of a swimming pool. Cut to an underwater shot of their struggle and both actresses are still wearing heels. Ouch.

Time flies! I just realized we didn't offer any feedback about our
participation in the Evernote DevCup back in July.
First of all, thank you so much for your support! We ranked 14th out of 174
contestants in public voting! That actually exceeded our expectations as we
aimed for the 20th position (so drinks are on Julien!)
But even with all of your support, we didn't make it to the finals. We would
have loved to fly to San Francisco, but the six
finalists all feature rich apps that merit their position. Congrats
guys, and good luck! The conference is in a couple of days now, and I can't
wait to find out who will win the cup!
As for us, it was a truly great experience! Remember our
post
announcing our participation? Well, outside the slight frustration of not
going to SF, the couple of days we spent building the Search for Evernote app
was really worth it!
- We were able to correct a few corner case bugs which this new use case highlighted. It's always better to find them yourself than let app developers stumble upon them :)
- We developed a new feature enabling prefix search on all words.
- Our participation led to an improved awareness of the company and helped our SEO.
- We created a new demo of the search lib which is much more compelling than Cities Suggest in many situations. It is actually a bit more than a demo for some people - as of today, it has 317 active users on google play!
That got us thinking... we may do this kind of contest again. But this time
we'll aim higher!
16 Aug 2012
After a few months in the
making, our first mobile library is finally ready to hit the shelves! Well,
nearly! Before releasing it, we want all the feedback you can give us to
ensure it's bug-free, easy to use and responsive to your needs.
If you subscribed to the beta, you should already have received your access
info. If not, you can request it directly on www.algolia.com.
You'll be able to download both the iOS and the Android versions, along with
all necessary documentation. Feel free to ask for any clarification or
additional info. We'll do a few technical posts which explore the product
internals in the coming months.
We're now eager to read your feedback! You just have one address to remember
to report bugs, request features, or anything beta related<EMAIL_ADDRESS>Enjoy!
01 Aug 2012
Let's rewind time a bit. Back in June was the famous Apple Developer
Conference, aka WWDC 2012. Algolia didn't even have a website at that time,
but what we did have is a friend who would attend:
Thomas! That was an occasion we could not
pass!
Thomas agreed to speak about us a bit and to invite people to visit our
website. That simple action defined our deadline to have a website up and
running. But wait! That would be better if people could also find the site
when Googling our company name. That meant a few days to allow for indexing...
and a tight deadline!
About two weeks of brainstorming and implementation went into the web
site. Our goal was to have a clear presentation of
our mobile search lib... and to be found on Google! And you know what? It's
damn difficult to do so in so short a time! Our site was up and running two
days before the conf and we immediately submitted it to all search engines.
Unfortunately we were not in first position when Googling for Algolia :(
Fortunately, things improved without delay. Two actions were particularly
useful in helping our search rankings: our participation to the Evernote
DevCup,
and our blog opening! We quickly got the pole position for our brand and
started to rank well for some key queries like mobile instant
suggest :)
We also thought about creating some posters that explain our technology, but
eventually we were so concentrated on the web site that we passed.
Result: Some awareness, one subscription to beta and more importantly, a
running website! Next marketing related action would be to have a demo ready
for LeWeb in London, but that's another story...
And here is what you could see on WWDC whiteboards:
Thank you again for your help Thomas!
24 Jul 2012
When it comes to programming languages and performance, you can read all and
its opposite on the web. It's definitely a very controversial topic!
[Edit 15-Nov-2012] I had questions on reddit about the data-structures and algorithms we used. We develop an embedded search engine for mobile, and tests were done on our own data-structure that is far more efficient than SQLite or other platform options for this use-case. [/Edit]
For Algolia the story started when researching an instant suggest algorithm. I
used Java for two reasons:
- Main reason: our first client was using Java on Google App Engine
- Secondary: at that stage, I was doing a lots of refactoring and Eclipse is very efficient for these tasks
Once our algorithm was designed, I started to optimize performance on a
desktop computer (core I7 950). For this, I indexed all titles of the English
version of Wikipedia (4 millions titles). I optimized the Java code mainly by
reducing the number of allocations. All instant suggest queries were then
faster than 10ms.
As we planned from the begining to support iOS and Android, I needed to
optimize for high performance on mobile. I then ported the Java code to
Android and ended up with a few modifications (we needed to support old
Android versions which have not a full support of Java SDK).
In order to test performance, I created a small "demo" app: CitiesSuggest, a
mobile application based on Geonames database to look for a city name. I
filled the index with all places with a known population. In the end, the
database contained 270 000 city names.
As could be expected, the resulting application was quite sluggish on my
Galaxy S2. The worst queries could take more than one second of CPU.
I then applied all possible methods described in the Anroid
documentation
and was able to reduce the response time to 700ms for the longest queries.
This is better but still gives end-users an impression of sluggishness!
Fortunately, common queries worked well enough to present our very first demos
at LeWeb'12 London. I was subsequently able to improve the user experience a lot
by adding asynchronous support. At that point, we decided to start
implementing the objective-C version for iOS.
I started a new implementation fully done in objective-C from scratch without
any premature optimization. I then developed the same CitiesSuggest
application for iOS. I first got stuck with some basic UI stuff. For example I
needed to reimplement an UILabel that supports highlighting! The standard
UILabel does no support this, and other implementations like Three20 just have
too many dependencies (you can download AlgoliaUILabel on
github, I released the code under Apache
licence). Once the UI was ready, I could see the actual performance was
catastrophic! Instant suggest queries were between 200ms and 10 seconds on an
iPhone 4S!
After profilling, I discovered that 95% of the time was spent in Objective-C
messaging and ARC. Actually, I have millions of calls to very small methods
with 1 or 2 lines of code, and I found a very good explanation in the internal
of objcmsgSend (mainly on mikeask.com. There is in fact a hash table
lookup behind objcmsgSend! This explains most of my performance problems.
To fix these problems, I started to replace all this low level objective-C
implementation by a C++ implementation with inlined methods. Eventually, I
finished with Objective-C code for high level classes while all the core was
C++.
This change has dramatically improved performance with instant-search queries
between 2ms and 90ms on a iPhone 4S. I struggled to find complex enough
queries to reach 90ms! This resulted in a very nice user experience with a
remarkably slick demo :)
After this succes, I decided to use the same C++ code on Android with Android
NDK. With this approach I reduced our maximum query time from 700ms to 80ms on
a Galaxy S2. But I was really disappointed by the Android display, as I did
not reach the same level of interactive experience that I had with iOS. The
display of results stays slower on Android, probably because I did not spend
enough time to optimize this part.
In the end, I lost a lot of time with Java and Objective-C trying to optimize
code when the real solution was to use C/C++. I am fully convinced that it is
just not possible to reach the same speed with Objective-C only or Java only.
And there is also another good property with C++ code: Blackberry supports
C++, and there is large chance that Windows Phone 8 SDK will support C++ when
released in a few weeks. Actually, I do not see any other alternative than
C/C++ when you are looking for performance on mobile devices, which is our
case :)
I hope this article will prevent you from spending as much time on
Java/Objective-C optimizations as I did.
12 Jul 2012
I started developing for iOS in 2009 by learning about the Objective-C
language. At that time ARC (Automatic Reference Counting) was not yet
available and developers were responsible for alloc/release/autorelease. I
found it pretty straightforward as it was very similar to C++ and the
resulting code was very self-explanatory.
When ARC was released at the end of 2011 it made a great impression on me and
looked like the perfect feature for any programmer coming from the Java world
who was not familiar with memory management. I started using ARC and
discovered a major flaw that completely changed my mind. Here is an example :
[Edit 28-Jan-2013] This post describes a bug in ARC that was fixed in Xcode
4.4.[/Edit]
Let's start with an example in C++, the sample contains a constructor that
allocates two vectors, a destructor that destroys them and a compute method
that just performs a swap between the two vectors. This code is perfectly
valid and a swap is the perfect operation when you have two sets of data to
maintain because this is very efficient (just two pointers copy, no data
copy).
class Example {
public:
Example() {
nextPositions = new std::vector<int>();
currentPositions = new std::vector<int>();
}
~Example() {
delete nextPositions;
delete currentPositions;
}
void compute() {
// some code here
std::swap(nextPositions, currentPositions);
// some other code here
}
private:
std::vector<int>* nextPositions;
std::vector<int>* currentPositions;
};
Before ARC the objective-C code was very similar and perfectly valid:
// headers
@interface Example : NSObject {
NSMutableArray* nextPositions;
NSMutableArray* currentPositions;
}
-(void) compute;
@end
// implementation
@implementation Example
-(id) init {
self = [super init];
if (!self)
return nil;
nextPositions = [[NSMutableArray alloc] init];
currentPositions = [[NSMutableArray alloc] init];
return self;
}
-(void) dealloc {
[super dealloc];
[nextPositions release];
[currentPositions release];
}
-(void) compute
{
// some processing stuff here
NSMutableArray* tmp = nextPositions;
nextPositions = currentPositions;
currentPositions = tmp;
// some processing stuff here
}
@end
The semantics are very clear, it is exactly the same as in C++.
So when you start using ARC you tend to do exactly the same thing with less
code, and you just delete the dealloc method:
// headers
@interface Example : NSObject {
NSMutableArray* nextPositions;
NSMutableArray* currentPositions;
}
-(void) compute;
@end
// implementation
@implementation Example
-(id) init {
self = [super init];
if (!self)
return nil;
nextPositions = [[NSMutableArray alloc] init];
currentPositions = [[NSMutableArray alloc] init];
return self;
}
-(void) compute {
// some processing stuff here
NSMutableArray* tmp = nextPositions;
nextPositions = currentPositions;
// Wrong, at that step this is too late! nextPositions was deallocated
currentPositions = tmp;
// some processing stuff here
}
@end
The error does not come from a missing strong attribute, because instance
variables are strong by default. The problem is that ARC does not generate
code in the variable assignation. You should explicitely add properties and
use "self.variableName" notation like in the next example. I would encourage
ARC designers to read this excellent article by Joel Spolsky "Making Wrong
Code Look Wrong". This ARC
usage is a perfect example of wrong code that looks perfect but leads me to
the conclusion that ARC is not trustworthy.
Here is the correct version:
// headers
@interface Example : NSObject {
NSMutableArray* nextPositions;
NSMutableArray* currentPositions;
}
-(void) compute;
@property (strong, nonatomic) NSMutableArray* nextPositions;
@property (strong, nonatomic) NSMutableArray* currentPositions;
@end
// implementation
@implementation Example
-(id) init {
self = [super init];
if (!self)
return nil;
nextPositions = [[NSMutableArray alloc] init];
currentPositions = [[NSMutableArray alloc] init];
return self;
}
-(void) compute {
// some processing stuff here
NSMutableArray* tmp = self.nextPositions;
self.nextPositions = self.currentPositions;
self.currentPositions = tmp;
// some processing stuff here
}
@synthesize nextPositions;
@synthesize currentPositions;
@end
I am surprised Apple hasn't corrected that flaw yet. This is a major issue as
ARC does not generate code for variable affectation like it does for
properties (if one of you reads this post and has a complete explanation,
please tell me!):
- Is it because of a performance issue? I would prefer to have no ARC at all than to see such a behavior.
- Is this case too complex to be handled? The problem is it undermines ARC's utility and might get stuck at the prototype stage.
To me, this is a perfect example of a technology driven product. The engineers
know their product so well that they forget to step back and look at it with a
fresh eye to analyse the full complexity of their system.
And that leaves me with two important lessons we'll try to apply to our
products:
- Always organize user tests, even when your users are developers themselves!
- Always keep a fresh eye when trying to simplify a product (this one may prove particularly difficult!)
I hope you'll tell us when we will (inevitably) break these rules!

In this tutorial, we propose the Hum method to approximate numerically the control in a null controllability problem for a non linear population dynamics model structuring in age and spatial diffusion.
For given the positive function $F$, we consider the following Population Dynamics Model Structuring by age and spatial diffusion:
where, $\Omega$ is a boundary subset of $\mathbb{R}^{N}$, $A$ is the maximal age and $T>0$ the final time. Also, $\Theta=\omega× (a_1,a_2)× (0,T),$ is the control support. Here, $\beta$ is the fertility rate depending also the age a, $\mu$ the mortality rate depending of the age a, $y_0$ the initial condition in $L^2(\Omega× (0,A)),$ $V$ is the control term and $y$ represent the density of the population of age $a$ at time $t$ and location $x∈ \Omega.$
We assume that the fertility rate $\beta$ and the mortality rate $\mu$ satisfy the demographic property:
and
where
The function $F,$ verify:
Numerical Simulations
In this part, the objective is to illustrate numerically the approximate null controllability of the nonlinear problem.
Indeed, we consider the following system:
Discretization and simulation of uncontrolled system
The idea in this part is to highlight the numerical simimulation of the nonlinear problem. The first parts is to reduce the PDE to the finite dimensional system of the form
where $A_l$ and $B$ are matrices, and
is the finite dimensional state and control vector. Here, VectorF is the contribution of the nonlinear part, which comes from births. So let’s consider the following system
where
To solve $(4)$, the space (dimension 1) and age discretization is performed with finite difference method on rectangular grid
on $[0,L]\times [0,A]$. For a given rectangular grid $\mathcal{T}$ with vertex $(x_i,a_j)\quad 1\leq i\leq N,\quad 1\leq j\leq M$ and uniform step size (without loss of generality) $\Delta x$ in $x-$direction and $\Delta a$ in $a-$direction, we denote by the diameter of the grid
The finite difference approximation of the diffusion term of the operator $\textbf{A}$ is given by
The finite difference approximation of the aging term of the operator A is given by
Let $y_{i,j}(t)$ be the approximation of $y(x_i,a_j)$ and
where $y_{i,j}$ is at the position $i+j*(N-1)$ and $A_l$ the matrix of the mortality approximation, the diffusion approximation and the aging approximation.
Take into account the newborns
We denote by $\beta(a),$ the fertility rate, the newborn is given by:
We approximate $\int_{0}^{A}\beta(a)y(x,a,t)da$ by
Then
But as
then
We create also the nonlinear vectorF from the births. Indeed, if we denote by
the matrix of the births,
and we define the vectorF by:
The corresponding discrete system is given for a continuous initial solution $y_0$ by
Example 1
Simulation of the uncontrolled system:
For the simulation, we take $L=1,\text{ } A=10\text{, }\Delta x=1/54\quad \Delta a= 5/54$ and $T=40$. Moreover $F(t)=t\Phi(t)$ a Globally Lipchitz function where
The fertility $\beta$ is given by:
here $v=1$, $\gamma=5$, $\alpha=7$ and the mortality rate $\mu$ by
Video 1. Evolution of the state of the uncontrolled system between t=0 and t=30
We observe in this video the growth (aging) of news borns over time. We also notice the high birth rate of this population.
Construction of the control and numerical simulation
We construct the control problem, which consists in minimizing the functional and we choose the classical Hum functional and the control matrix $B=\chi_{\Theta}$ where $\Theta=(x_1,x_2)\times (a_1,a_2)\times (0,T),$ and we suppose that $U_T$ is the desired state:
Here $U_T=0.$\
The approximate null controllability become the minimization of the functional $J,$ where $(U_l,V_l)$ verify the following system
In this part the fertility $\beta$ is given by:
here $v=1$, $\gamma=5$, $\alpha=7$
and
and $VectorF=(P_lU_l).^2$.This means that we consider that $F(t)=t^2$ which is globally lipchizt on a compact which is our case.
The system becomes:
Example 2
In this example, we take $ε=0.05$, $\Delta x=0.05$ and $\Delta a= 0.5$, with the initial condition
the following numerical results were obtained for $T=12$ and $\Delta t=120$.
Evolution of the control V between t=0 and t=12.
Video 2. Evolution of the state of controlled system between t=0 and t=12
We notice that, with a control domain that takes into account the most populated part of the domain, the Hum method applied to the Casadi algorithm gives us an interesting approximative controllability result while maintaining the positivity of the density.
Evolution of the controlled state (density of the population) between t=0 and t=12.
Video 3. Evolution of the control function between t=0 and t=12
Example 3
Here, we keep the same parameters of the Example 1 but we change the final time (here T=20) , and we take $\Delta x=1/18$, $Δ a=5/18$, $\epsilon=0.05$ the following numerical results were obtained:
Video 4. Evolution of the state of the controlled system between t=0 and t=20
Video 4. Evolution of the state of the controlled system between t=0 and t=20
Example 4
In this part we consider a smaller control domain. Indeed we take
$\Theta =(0,2/5)\times(0,4)\times(0,T)$.
In addition we also remove $\epsilon=0.001$ and $T=20.$ The rest is identical to the data of example 2.
We obtain the following numerical results:
Evolution of the control V between t=0 and t=20.
Video 4. Evolution of the state of the controlled system between t=0 and t=20
Here although the result is acceptable, we notice that the state of the controlled system is negative for most of the time.\
Evolution of the controlled state (the density of the population) between t=0 and t=20.
Video 5. Evolution of the control function between t=0 and t=20
We notice here that the solution to the final time tends to 0, but during the time of control much of the state of the system was negative.
We notice that numerically we have approximation and the positivity of the state, if the support of the control covers the most populated part of the domain (space, age).
However it should be noted that we could not take a positivity constraint in our simulations. It should be noted that we have better approximations when we do not consider the cost of control.

| DOSE: |

GBL |
(liquid) |
After purchasing a quantity of “industrial degreaser” (99.9% GBL), I settled down on a quiet Sunday evening to experiment with it.
At 8:30 pm, I measured out 5 mL of GBL and poured it into a small juice glass. Unadulterated, the GBL had a moderate chemical odor, and smelled vaguely like gasoline, airplane glue, plastic, or turpentine. When I placed a small drop on my tongue, the taste was similar to the smell, and “burned” slightly - the same way hard liquor does.
I then added 2 small ice cubes and filled the remainder of the glass with pineapple juice. The taste of the GBL was still strong in the mixed product. Together, the GBL & juice tasted like a fruity mix of bathtub gin and pineapple – only more “chemical” and “kerosene-like”. While not pleasant, it was palatable.
Immediately after drinking, my face flushed and my heart sped up. This was likely due to nervous excitement, though I mention it in the interest of completeness.
However, within minutes (T+0:05), I began to experience mild intoxication. The onset of symptoms was rapid. By T+0:07, my face was feeling flushed and there was a general skin “tingliness”. At this point, I felt mildly dizzy, drink, and happy. It was a happy, loving feeling.
Symptoms continued to increase over the next ten minutes. I remember being amazed at the speed at which GBL acted. By T+0:15, it was extremely difficult to keep a written record of events, but my thoughts turned to food and sex. I felt the urge to stand and spin around, despite the lack of TV, music, or other people. Euphoria, dizziness, and intoxication continued to increase.
Events from T+0:20 onwards are extremely blurry. At T+0:30, I passed out.
At T+2:00, I woke up, feeling nauseous. While I was still intoxicated from the effects of GBL, there was slightly more “control” to the feeling than, say, being drunk from alcohol. I made my way to the bathroom and vomited several times.
I had previously eaten a light snack of carrots and dip. In retrospect, I would not recommended consuming anything prior to use of GBL.
After emptying my stomach, I settled back down on the couch and passed out within 15 minutes or so. (T+2:15)
At T+4:25, I woke up again. I was mildly hungry, and almost completely sober. Because it was late (1:15 AM), I decided to go back to bed, though this was more of situational decision than one brought on by the GBL. That is, I had more or less completely returned to baseline by this point. I had some difficulty getting back to sleep, though I often suffer from insomnia and cannot be certain whether this insomnia was a rebound effects from the GBL.
In retrospect, GBL strikes me as a drug with a great deal of potential, based on my limited enjoyment of the effects. Before passing out, symptoms were pleasant and had the potential for recreational enjoyment. It is clear, however, that even mild overdoses can lead to drowsiness and nausea. In the future, I will attempt a smaller dose.

Batteries, Starters And Charging
Imagine this. You’re running late for work. You finally make it to your car and turn the key in the ignition only to realize your battery is dead. It’s a strong, sinking feeling. We know, we’ve been there. You not only have to determine how you’ll get to work, but you’re probably left wondering how you could have a dead battery when you didn’t forget to turn off your lights or electrical system
First things first. Before accepting that your battery is dead, double check that it is properly secured in your vehicle, and that all cables and terminals are clean and connected tightly. A battery may still have life left to give if it stopped working because of a weak connection. And if you need help with jump starting your vehicle, read our step-by-step instructions here.
Other Starting Problems
t’s also important to note that if your car won’t start, the battery may not be the only culprit. Problems starting can also be an indicator of a bad starter or alternator.
Your starter is what actually cranks your engine. When a starter isn’t working properly, the engine may start with difficulty, or won’t start at all. Starter issues may stem from electrical or mechanical failure, or from it breaking down completely.
Additionally, your alternator is responsible for two important tasks involved in powering your vehicle. First, it recharges your battery while your car is running, and second, it also works with your battery to operate integral electrical components, such as headlights, windshield wipers, and more. A damaged alternator can cause erratic electrical functions or prevent your engine from running.
Dead or Weakened Battery Warning Signs
A common misconception about modern car batteries is that they’ll give you plenty of warning before they give out. While it is true that vehicles used to start slower and slower before a battery finally died, most modern batteries have evolved to work at full capacity until they just can’t anymore. Though it’s nice that batteries today function longer than they used to, you have to look for smaller signs that it may be on the fritz.
Don’t End Up Stranded, Service Your Battery, Starter, or Alternator Today!
Don’t get left stranded, relying on a Good Samaritan to help you jump your car. If you’ve noticed your battery is on its way out, let us get you a new, quality battery, so you can get where you need to go reliably. Book an appointment today with your local Christian Brothers Automotive location.
Once we know what we’re facing, we will offer you the best, most cost-efficient solution. We will walk you through the repair process every step of the way, keeping you informed of cost, parts needed, and repair turnaround time.

summary: The hello-world of snappy apps
description: This is a simple hello world example that includes a
interesting apps to play with snappy and the sandboxing in snappy
hello-world.echo - simply output text
hello-world.env - dump the env of commands run inside app sandbox
hello-world.evil - show how snappy prevents apps to do stuff outside their sandbox
hello-world.showdev - depreated - will be replaced with skills
hello-world.usehw - depreated - will be replaced with skills example
hello-world.sh - enter interactive shell that runs in app sandbox

Ingredients
2 1/2 cups uncooked quinoa
4 1/2 cups vegetable stock or water
2 tablespoons pesto sauce
2 teaspoons arrowroot powder or cornstarch
2 cups fresh spinach
12 ounces mozzarella cheese
1/3 cup parmesan cheese
12 ounces fresh broccoli florets
3 green onions
Directions
Preheat the oven to 400F.
In a 9x13 baking rectangular dish place the quinoa and green onions. On the meantime, place the broccoli in a large bowl and microwave on high for 4-5 minutes. Set aside. My microwave is not very powerful so this is how long I did it for without the broccoli getting mushy. If you have a powerful microwave you may need just 3 minutes as it will continue to bake in the oven for about 5 minutes.
In a large mixing bowl, with a wire whisk, mix the vegetable stock, pesto, arrowroot powder and salt. Heat mixture until boil. You can do this on your stove top or microwave. I used my microwave.
Add the vegetable stock to the quinoa followed by the spinach, parmesan and 3/4 of the mozzarella cheese. Bake for 30-35 minutes. Take the quinoa casserole out of the oven and mix in the broccoli. Sprinkle the rest of the cheese over the quinoa and broccoli and place back in the oven for 5 minutes or until the cheese has melted. If you like you can add more parmesan cheese over the top as well.
I place my casserole under the broiler for 2-3 minutes to brown the top but this is just optional. Serve while still warm.


PPMB Files
Portable Pixel Map (binary)
PPMB is a data directory which
contains examples of the binary version of the PPM portable pixel map format.
It is a simple RGB color image description. The definition is as follows:
-
the typical file extension is ".ppm", but an extension of
".pnm" is also occasionally used.
-
A "magic number" for identifying the file type. A
binary PPMB file's magic
number is the two characters "P6".
-
Whitespace (blanks, TABs, CRs, LFs).
-
A width, formatted as ASCII characters in decimal.
-
Whitespace.
-
A height, again in ASCII decimal.
-
Whitespace.
-
The maximum color-component value MAXVAL, again in ASCII decimal.
For the binary format, MAXVAL cannot be any greater than 255.
-
a single charcter of "whitespace", usually a new line.
-
Width * height pixels, each pixel being described by 3 bytes, each
between 0 and the specified maximum value, starting at the top-left
corner of the pixmap, proceeding in normal English reading order.
The three values for each pixel represent red, green, and blue,
respectively; a value of 0 means that color is off, and the maximum
value means that color is maxed out.

The folks over at Madison.com put together a video of the crowd that gathered Halloween night on state street (before the pepper spray was broken out). And they used our song "Hot Water Avalanche" as the background music.
Check it out.

Data Sources
My Data is coming from three sources: The Openbrewery Database, The Brewer's Association and the United States Census Bureau. I am using location information from the Openbrewery DB, estimated brewery founding dates from the Brewer's association, and the American Communities Survey (ACS) aggregated at the county geographic level from the Census Bureau.
The Data Itself
Openbrewery Database
The Openbrewery Database contains information on about 8000 breweries. The Openbrewery Database has information on breweries in planning, but I decided to exclude them from my analysis for two reasons: First, I can't be sure that their coverage of breweries in planning is perfect. Second, I don't know how serious those plans need to be in order to be included. I can't be sure that both two friends in their garage who are "totally going to do it" won't be weighted the same as an investor who has assembled $2M, contracted a master brewer, and only needs to find a space.
The database also contains location information on the breweries. For most, this includes both street address and latitude/longitude (4600/7000). In order to intersect this data with the counties they are in, I could only consider those breweries which had latitude/longitude information. I increased the number which had latitude/longitude information significantly by geocoding (6000/7000), but I was unable to get the remaining 1000 or so breweries' latitude/longitude, and they had to be excluded.
Brewers' Association
In my initial analysis, I was only trying to predict the number of breweries that a county would have based on its demographics. This presented two issues: I had no way of knowing what the ground truth was, and I wanted to make a prediction for the next year. Without knowing which breweries were around in which years, I couldn't make a time-wise train/test split. I contacted the American Brewers' association since they had an interesting visual about the growth of the craftbrew industry (
you can find that here). They were kind enough to provide me with a dataset which consisted of brewery company names and the date they were founded or an estimation of that date.
This allowed me to slice my dataset by year, and see what each county's brewing scene was like for each year. In order to make my job a little bit easier, I looked only at whether or not at least one brewery opened in a county in a given year. This means that my model does not distinguish between counties where one brewery opened in a year and a county that had five open in a year. I decided to only consider the years from 2000-2017 as features for my model training, and used 2018 as my prediction vector.
US Census Bureau's ACS
The ACS reports demographic information in categories such as age distribution, racial composition, and education levels at the census block level. It also provides economic statistics of residents in areas such as rentership status, home ownership rates, income, and education. Even further, it provides lifestyle indicators such as methods of transport to and from work, whether or not people have roommates, and the percentage of residents who were born in a different county. The version of the ACS I used was taken from the Missouri Census Data Center, which aggregated the information at the county level.
I selected the five-year aggregation from 2012-2017 as the version I would work with, as it had the most complete and comparable information across counties. I could use a dataset with a smaller time window, but the margins of error on the statistics between counties would be larger, some of the data would be incomplete, and some counties would be missing entirely.
I used state information as a categorical feature by one-hot-encoding it. I also dropped the columns which corresponded to Margin of Error information, as I had no reason to believe that the margin of error in a county would be in any way predictive of whether a brewery would open in that county.
PCA, Train/Test Split, and Binary/Demographic split
I performed Principle Component Analysis on my data and saw that the population of a county seemed to account almost entirely for about 40% of the variance in my data. This was largely due to outliers such as Los Angeles County California which has an estimated 10,000,000 residents and is the most populated county in the United States. The median population of counties in my dataset was 25,700. As a result, I only considered counties with populations less than 1.4 M while building my model. This improved my PCA variance percentage a bit, but primarily it served to make the distribution more representably samplable.
I performed a shuffle of my data, as it was currently ordered by State, and made an optimization/test split of 9:1 and sequestered my test set from my model. I then did a train/validation split of 6:4, so I could accurately predict the performance of my model on the test set. I chose this size of split because in a test of train/validation split sizes on a very early model, I saw that performance did not increase much with the number of samples I had in my training set.
I plotted my optimization set with my test set in PCA as well as my training set with my validation set. I felt that by eye, my test set constituted a representative sample of my total dataset, so I felt comfortable moving forward. I also did not notice a significant bias in my train/validation split in the higher-population regime.
The Model
I split my dataset into two dataframes for building two separate models. Both are random forest classifiers, but I wanted to be able to select hyperparameters for the different datatypes separately. I used hyperopt to make hyperparameter selections. For my binary feature model, my loss function to minimize was -(validation set accuracy), and for my demographics model, my loss function was -(validation set ROC AUC). I combined the decision function outputs of my two random forest models with a logistic regression.
Model Training
During training, I evaluated model performance by inspecting Precision/Recall curves and Receiver operating characteristic curves to determine whether my model was overfitting. Below are the PR and ROC curves for my individual models.
The takeaway here is that neither on its own is standing out as performing very well. And when I combine their predictions by logistic regression, my performance on the validation set doesn't blow me away either.
However, when the performance from the full optimization set is compared to performance of the test set, the difference between the demographic model (the better performing of the two) and the full model is apparent. The full model clearly performs better on unseen data and generalizes very well.
