Service pattern for {{ pageTitle }}
{% include "includes/index_metadata.html" %}This page is for people who work in local authorities. It outlines a common pattern used for providing resident's parking permits services effectively. Read more about service patterns.
Example service
While reading the service pattern description, explore the example council service.
What is the user need?
Residents need a place to park their car near their home. Parking permit services make sure there are parking spaces available for residents. They make it illegal to park in some areas without a permit.
We recommend putting users first when designing your parking permit service.
Understand other user needs for this service
What does your service need from users to deliver this service?
Depending on your local authority's needs, the user may be asked to provide:
- the postcode of the area where they want to park
- proof they live in the area
- the registration number of the vehicle to be permitted
- payment (supports the cost of the service and may vary from council to council and within the service, depending on for example vehicle and parking zone)
What is the user journey?
These are the steps users should go through.
1. Awareness
Users should find out about the parking permits service before they need to park their car. This could be through:
- council messaging when they sign up for council tax payments
- estate agent information when they buy their house
- street signage
Your service needs to make sure correct information is being provided through all channels within your control.
2. Finding the right council
When the user knows they need a permit, they need to get to the right council's website to apply. Users might start by typing 'parking permit' into a search engine, or going to the website of the council where they think they need a permit.
Search engine
The GOV.UK parking permits page is the top result in most search engines. It should send users to the right council's website when they enter their postcode. Your service needs to make sure the postcodes it provides services for are linked to the right page on their website and email any corrections to<EMAIL_ADDRESS>Council website
Users may also go straight to the website for the council they think they need to get a permit from. This makes it very important for your service's webpage to clearly state which area your parking permit service covers – as the user may be in the wrong place.
3. Parking start page
Some users may not go through the two steps above. They may arrive on your council's website with a need to park, but no knowledge that they need a permit. So it's important to explain they may need a permit.
4. Routing to the right boundary
You need to find out where the user wants to park your service can:
- give the user a permit for the right parking boundary
- let the user know if there are no permits available for the area where they want to park
- check the user is a resident in the parking boundary where they want to park
The best way to do this is through a postcode lookup tool, as this is the easiest and fastest way for users to find and understand information they need about where they can park.
It should be done at this early point in the user journey so that the user doesn't go through unnecessary effort.
Explore the where do you want to park example council page
At this point your online service should also check if there are permits available in the area the user wants to park in. If permits are available, move the user onto the next step. If not, the council should tell the user what their alternative options are, based on the nearest boundaries with permits available.
5. Picking the right permit type
When the council knows where the user wants to park and that permits are available, they can tell the user about the parking boundary and ask if they are a resident of that area.
Explore the resident or visitor example council page6. Resident's start page
Now the user is in the right place, this page should communicate:
- types of permit users can apply for (if applicable)
- permit eligibility requirements
- where the permit they are applying for will allow them to park
- at what time the permit they are applying for will allow them to park
- how much the permit will cost
- how long the permit is valid for
- what information they need about the car for example vehicle registration number
- how long the process usually takes
- what to do if they need assistance with the application
- if the service differs from this pattern, include any other information the user needs to provide
7.  Confirm address and eligibility
GOV.UK Verify will send the council the user's address, as supplied by the user's chosen identity provider. When the user returns from the GOV.UK Verify process, your service's webpage should ask them to confirm if this is their current address.
Explore the confirm name and address example council pageIf the user says the address supplied through GOV.UK Verify is not correct, they are likely to be a new resident whose address has not been updated with their identity provider. The user should then be asked to enter their current address and be warned that they must not enter false information.
Explore the enter current address example council pageIf the parking permit your council issues is physical, your service can gain extra confidence that the applicant's address is current by mailing the permit to the address they've confirmed in their online application. Mention you'll be using the address for this purpose on the confirmation page.
If the permit your council issues is digital and your serice wants extra confidence of eligibility, you can issue a short-term permit, for example for 3 months. After this time, the user's identity provider should have the new address and the user can re-apply using GOV.UK Verify.
9. Address check for validity and permit numbers
a. Does the user live in the area?
At this point your service should check if the user lives in the eligible area, and if they do show them a message confirming they are eligible. This can be done by checking the user's address against your council's database of parking permit zones.
Explore the not eligible due to address example council page
b. Does the user or the user's address already have a permit?
Your council may limit the number of people who can get a permit, or number of permits allowed per address. At the point where the online application checks address eligibility, it should also check if any permits are currently assigned to the person or their address and issue an ineligible message if applicable.
Explore the not eligble due to number of permits example council page
c. Is the user eligible for multiple permits?
If the user is eligible for multiple permits, for example visitors permits, your service should ask which type of permit the user would like to apply for.
10. Enter vehicle registration
Some councils require the permit to be associated with a specific vehicle.
If your service requires this for enforcement purposes, your service's webpage needs to specify that this is why you need the data.
In some councils, the permit price varies depending on the vehicle type, emissions, make or other conditions.
If your council requires this information, your service can look it up using DVLA's vehicle details API. In this case, the page should explain to users that their registration number will be used for this purpose as well.
11. Choose a permit
This page should only be displayed if the user has a choice of permit at this point. Generally local councils give users a choice of 6 month or 12 month permits.
If your sercvice has used the DVLA vehicle details API, it should display the returned data to the user and explain that the vehicle price has been calculated based on that information.
12. Pay
Permit fees will vary based on fee calculation rules determined by each individual council. In some cases the permit may be issued free of charge, for example, if the resident is the first member of the household to apply.
Explore accepting payments example council pages
Your service can accept payment via a number of channels, including checks, bank transfers or online payments. Councils can find a supplier on the Digital Marketplace.
In the future, your service will be able to accept payments using GOV.UK Pay.
13. Receive permit confirmation
After payment, the user needs to receive a confirmation of payment and an acknowledgement that their application has been successful. They should also receive information about how the permit will be enforced (see step 8).
If the payment cannot be accepted or if the application fails, for example it times out, the user should be shown an on-screen message that specifies the next steps to take to continue with the application.
Your service should ask the user how they would like to receive this confirmation of payment, offering the choice of email, letter or text. See the example page on how to do this.
In the future, your service will be able to send this confirmation using GOV.UK Notify.
14. Contacting users
You may want to capture users contact details so they can be contacted if things go wrong with their application, or for use in future for renewal reminders.
Allow your users to select their prefered contact method and only contact them in this way in future.
15. Checking permits
It's better for users and cheaper for government if permits are issued electronically. Wardens check electronic permits by entering registration numbers into a handheld device linked to a database.
If your service hasn't yet moved over to an electronic permit system, it should have a plan in place to move over.
Until then, your service should mention in the physical permit payment receipt
- how long the user will need to wait for a permit to be posted to them
- if the user can pick up their permit from a council office to get it faster and where that is
- if the user can print a temporary permit themselves while they wait for a permanent one
- this information should also be communicated on the council's start page at the beginning of the user journey
- advice on how customers can park without their permit until they receive it
This information should also be communicated on your service's start page at the beginning of the user journey.
Temporary permits should clearly show their expiry date so wardens and users can check them easily.
16. Renewals
Your service should remind users when it's time for them to renew their permits, using the same contact method used for the payment receipt.
See the example renewal notification. (Page in progress)


Overview
Thread pool is a collection of managed threads usually organized in a queue, which execute the tasks in the task queue.
Thread pool is a group of pre-instantiated, idle threads which stand ready to be given work.
A sample thread pool (green boxes) with waiting tasks (blue) and completed tasks (yellow)
Why Thread Pool?
Thread Pools are useful when you need to limit the number of threads running in your application at the same time.
Thread pools are often used in multi threaded servers. Each connection arriving at the server via the network is wrapped as a task and passed on to a thread pool. The threads in the thread pool will process the requests on the connections concurrently.
Many server applications, such as Web servers (eg. Tomcat), database servers, file servers, or mail servers must process a large number of tasks received from a network protocol. Often, the task is short-lived and the number of requests is large.
Instead of starting a new thread for every task to execute concurrently, the task can be passed to a thread pool. As soon as the pool has any idle threads the task is assigned to one of them and executed.
Implementation
This is a simple thread pool implementation. The pool is implemented using a list of tasks, and a list of threads. Theads will fetch tasks and run it. The list is implemented with a BlockingQueue - however, it’s fine to use just a normal queue.
Main Class:
public class Main {
public static void main(String[] args) {
// In this example, we create 3 thread to run 10 tasks
// set the BlockingQ size to be 5.
ThreadPool tp = new ThreadPool(3, 5);
List<MyTask> todoList = new ArrayList<MyTask>();
for (int i = 1; i <= 10; i++) {
todoList.add(new MyTask("T" + i));
}
for (MyTask todo : todoList) {
tp.execute(todo);
}
while (!tp.noMoreTask()) {
try {
Thread.sleep(2000);
} catch (InterruptedException e) {
e.printStackTrace();
}
}
tp.stop();
}
}
Pool Class:
public class ThreadPool {
// a list of tasks (BlockingQueue)
// a list of thread
private MyBlockingQueue taskQueue = null;
private List<MyThread> threads = new ArrayList<MyThread>();
private boolean isStopped = false;
public ThreadPool(int numThreads, int maxNumTasks) {
taskQueue = new MyBlockingQueue(maxNumTasks);
for (int i = 0; i < numThreads; i++) {
threads.add(new MyThread(taskQueue));
}
System.out.println("Thread pool initiated. ");
for (MyThread thread : threads) {
thread.start();
}
}
public synchronized void execute(Runnable task) {
if (this.isStopped) {
throw new IllegalStateException("ThreadPool is stopped");
}
try {
this.taskQueue.enqueue(task);
} catch (InterruptedException e) {
e.printStackTrace();
}
}
public boolean noMoreTask() {
return this.taskQueue.isEmpty();
}
public synchronized void stop() {
this.isStopped = true;
for (MyThread thread : threads) {
// thread.stop();
thread.interrupt();
}
System.out.println("Thread pool stopped. ");
}
}
Thread Class:
public class MyThread extends Thread {
private MyBlockingQueue taskQueue = null;
private boolean isStopped = false;
public MyThread(MyBlockingQueue queue) {
taskQueue = queue;
}
public void run() {
while (!isStopped()) {
try {
Runnable runnable = (Runnable) taskQueue.dequeue();
runnable.run();
} catch (Exception e) {
// log or otherwise report exception,
// but keep pool thread alive.
}
}
}
// public synchronized void stop() {
// isStopped = true;
// this.interrupt(); // break pool thread out of dequeue() call.
// }
public synchronized boolean isStopped() {
return isStopped;
}
}
Task Class:
public class MyTask implements Runnable {
String message;
public MyTask(String s) {
message = s;
}
@Override
public void run() {
// do some task here...
// finish the task ...
System.out.println("Task finished: " + message);
}
}
Output:
Thread pool initiated.
Task finished: T1
Task finished: T3
Task finished: T4
Task finished: T5
Task finished: T6
Task finished: T2
Task finished: T7
Task finished: T10
Task finished: T9
Task finished: T8
Thread pool stopped.

Exact segmentation: Pelt
====================================================================================================
Description
----------------------------------------------------------------------------------------------------
The method is implemented in :class:`ruptures.detection.Pelt`.
Because the enumeration of all possible partitions impossible, the algorithm relies on a pruning
rule. Many indexes are discarded, greatly reducing the computational cost while retaining the
ability to find the optimal segmentation.
The implementation follows :cite:`b-Killick2012a`. In addition, under certain conditions on the change
point repartition, the computational complexity is linear on average.
When calling :meth:`ruptures.detection.Pelt.__init__`, the minimum distance between change points
can be set through the keyword ``'min_size'``; through the parameter ``'jump'``, only change
point indexes multiple of a particular value are considered.
Usage

Country's female legends kick off 2019 CMA Awards
NASHVILLE, Tenn. -- Female acts may be scarce on contemporary country radio and the country charts, but they brought girl power to the 2019 Country Music Association with a resilient performance featuring top women from the genre, from Dolly Parton to Carrie Underwood to Reba McEntire.
The three acts, who are hosting Wednesday's show together, were joined by Tanya Tucker, Terri Clark, Crystal Gayle, Sara Evans, Little Big Town's Karen Fairchild and Kimberly Schlapman, Maren Morris, Brandi Carlile, Gretchen Wilson, Martina McBride and more, singing classic country songs across two stages.
After the performance Parton asked, "What do you call three women hosting the CMAs?"
"Your lucky night," she screamed.
McEntire added they joined forces to host the show and perform the opening number to inspire young women watching the awards show from their TV screens.
The trio performed "Until the Day They Lay Me Down" to start the show, which opened with several other medleys by performers including Tanya Tucker, Brandi Carlile and other members of the supergroup The Highwaywomen.

There's a strong trend in modern IT to migrate on-premises installations to cloud platforms. Independent of the migration strategy, either Lift-and-Shift or re-implement applications, this blog casts an eye on the popular Java platform deployed to the cloud.
Migrating to the cloud by just replacing machines of the own data-center by virtual machines in the cloud, does not provide much benefit, neither regarding costs nor in terms of administration effort. Therefor, the utilization of container orchestration platforms like Kubernetes or OpenShift is assumed in the following - if not even talking about FaaS or Serverless, the latest hype in cloud technologies.
Container orchestration platforms works best for MicroService architectures, ie. the shift to the cloud may have impact on the application architecture. Because this blog post wants to focus on the Java platform for cloud deployments, applications are assumed to be designed in a service-oriented way already.
When making a technology decision for cloud-native applications, it’s worth to start with a look at the first-class citizen of cloud application, the Golang platform. The features that make Golang stand out are speed and size - speed in terms of start-up and execution, size in terms of image size and memory requirements at runtime.
The classical Java EE environments are typically based on an application server and optimized for long-running applications, running on large servers. For such deployments start-up time and memory requirements are not that important.
One advice for building production-ready container images for Golang
applications is to create the images FROM scratch
, ie. don’t base
the image of a Linux distribution. The main reason for this is not to
reduce the image size, but to reduce the attack surface, which greatly
improves security.
Can we do the same for Java applications? Unfortunately not, because
the JDK isn’t statically linked like Golang applications are, but
dynamically linked against glibc
or musl
library. These libraries
are typically part of a Linux distribution.
For a small demo application, I used the
Thorntail generator
and selected the technologies JAX-RS + CDI + JSON-B
.
After extracting the downloaded ZIP file to a folder the application
can be started locally with
mvn thorntail:run
When the application server is ready the application can be used:
gunther@gunther-K501UQ:~/Downloads$ curl localhost:8080/hello -v
* Trying <IP_ADDRESS>:8080...
* TCP_NODELAY set
* Connected to localhost (<IP_ADDRESS>) port 8080 (#0)

Hello from Thorntail!gunther@gunther-K501UQ:~/Downloads$
gunther@gunther-K501UQ:~/Downloads$
The best you can do to keep the image lean is to use the OpenJDK linked
against the musl
library. That’s the case for Alpine Linux, a distribution
tailored for cloud environments. After building the application with
mvn clean install
, the demo application can be packaged into
an image by using the following Dockerfile
:
FROM openjdk:14-jdk-alpine
COPY target/demo-thorntail.jar /app/demo-thorntail.jar
EXPOSE 8080
CMD ["java", "-Djava.net.preferIPv4Stack=true", "-Djava.net.preferIPv4Addresses=true", "-jar", "/app/demo-thorntail.jar"]
The resulting image size is about 450 MB. The same application packaged into an image with a Wildfly application server gives a size of about 750 MB. That’s clearly shows, that application servers are not appropriate for containerized Java payload. However, compared to about 20 MB, which is the size of a Golang image with the same functionality, the Thorntail image cannot compete.
Additionally, the start-up time of the Java EE application takes - mostly because of classpath scanning and reflection to process JEE annotations - several seconds, while the Golang application is ready to use in some milliseconds.
Because classical Java EE applications are not a good fit for cloud-native platforms, several other options arise in the Java world at this time: Eclipse MicroProfile, alternative Java EE packaging like Hammock, Micro Frameworks like Micronaut, Helidon, Spring Fu, Javalin, Spark, Ratpack, Dropwizard or Akka, native images with GraalVM, etc. The approaches to evolve the Java platform to the future could fill books. It’s almost comparable to the situation of the JavaScript world a few years ago: Lots of different frameworks with unclear future. If you go for a framework today, you might end up with a unsupported platform in a few years. Eg. the Thorntail framework, although just about 4 years old (including the life-time of its successor Wildfly Swarm), is pretty much dead (see Thorntail Community Announcement on Quarkus).
The situation today is a bit ambivalent: Java is the undisputed number one programming language and platform, but not well suited for cloud native runtime environments. On the other hand everybody moves from classical on-premises servers to cloud platforms.
Because of the diversity of Java frameworks future-proof technical decisions are hard today. The best you can do from my point of view is to stay as close to JEE standards as possible. That’s the reason I’ll surely have a look at Quarkus in the near future.


Creating a key index is a good way to improve query performance when data is partitioned using a key or a field value. You can create key indexes by using the createKeyIndex
method of the QueryService or by defining the index in cache.xml
. Creating a key index makes the query service aware of the relationship between the values in the region and the keys in the region.
The FROM clause for a primary key index must be just a region path. The indexed expression is an expression that, when applied to an entry value, produces the key. For example, if a region has Portfolios as the values and the keys are the id field of the Portfolios region, the indexed expression is id.
You can then use the FunctionService (using the partitioned key as a filter passed to the function and as part of the query equality condition) to execute the query against the indexed data. See Optimizing Queries on Data Partitioned by a Key or Field Value for more details.
There are two issues to note with key indexes:
- The key index is not sorted. Without sorting, you can only do equality tests. Other comparisons are not possible. To obtain a sorted index on your primary keys, create a functional index on the attribute used as the primary key.
- The query service is not automatically aware of the relationship between the region values and keys. For this, you must create the key index.
Note: Using a key-index with an explicit type=‘range’ in the cache.xml will lead to an exception. Key indexes will not be used in 'range’ queries.
Examples of Creating a Key Index
Using Java API:
QueryService qs = cache.getQueryService();
qs.createKeyIndex("myKeyIndex", "id", "/exampleRegion");
Using gfsh:
gfsh> create index --name=myKeyIndex --expression=id --region=/exampleRegion
Using cache.xml:
<region name=exampleRegion>
<region-attributes . . . >
</region-attributes>
<index name="myKeyIndex" from-clause="/exampleRegion" expression="id" key-index="true"/>
...
</region>
Note: If you do not specify the type of index when defining indexes using cache.xml, the type defaults to “range”.

A $9,000 fee and 4 weddings in 2 days: The life of a professional bridesmaid.
by Billi FitzsimonsProfessional bridesmaid. I know, right? So many questions.
Who knew there was such a thing. But turns out not only does the service exist, it’s a popular (and lucrative) one, too.
Sydney woman Kerstyn Walsh, 29, attends about 30 to 40 weddings in a year, thanks to the business she created ‘Hire a Bridesmaid‘, which now employs another four full-time staffers. As a professional bridesmaid, her booking record, she tells Mamamia, is four weddings in two days.
Here’s our chat with Kerstyn…
How did you become a professional bridesmaid?
Totally by accident. I was a real estate agent for a really long time and then I wasn’t happy in that job anymore and I thought, “There’s got to be something else.”
A friend of mine who I went to school with asked me to be the MC at her wedding. She invited me down the night before the wedding, and she had left her lingerie at home so I said, ‘Don’t worry, I’ll go get it for you!’ So I drove back to Sydney and then I came back the next day.
Then, on the day, I was serving drinks for all the bridesmaids and I was hanging out with everyone and I just thought, ‘Oh My God, this is what I am meant to do.’
What made you think that the job of a professional bridesmaid was necessary?
What made me think this is so important is not just evening out numbers for the bridal party, but also having that person that just gets you and has your back on your day 100 per cent. Or, also, some of my clients are from overseas and they don't have anyone here for them.
You shouldn't have to stress on your wedding day. A professional is someone who's not going to feel bad about doing jobs on your wedding day, because it is literally their job. Whereas an actual bridesmaid might want to drink 50 wines and have a great time.
How much does the service cost?
Our full wedding service package, including if you want a bridesmaid on the day and how much is involved, can be up to $9,000 - that's all-inclusive.
It depends on if they're booking me 12 months out or six months out and how much help they actually need.
If they just literally needed me to turn up in the dress on the day itself, and do nothing beforehand, it would be $2,000, plus the cost of me being there, so travel and dresses.
When people ask how you know the bride and groom, do you make up a story?
That's tricky - it's a case-by-case basis.
Sometimes the bride will say, 'We've developed a friendship anyway.' Which is so true, you spend nine to 12 months with someone planning their wedding, so you do develop a relationship. And so I will just pick bits from that.
They don't need to know, 'I'm being paid this amount of money to be here today.' So I'll say, 'We're new friends, we started when the wedding planning process started and I've helped her through all of that and we've become quite close in that time.'
You don't need to go into too much detail. It's really important to develop a story that the couple are comfortable with.
Do you organise the hens party?
Sure do! Sometimes I do that in conjunction with the real bridesmaids, which is tricky because having so many different opinions can be hard.
I often say 90 per cent of my job is being tactical with people - you know, managing expectations.
Sometimes I'll get in touch with the bridesmaids and say, "You guys come up with the plan, tell me what you think the bride will want, and I will do all the work so you just have to turn up on the day." And they love that.
We chase up RSVPs and, on the day, if there are decorations, we do that. We do everything.
Have you ever had disagreements with real friends in the bridal party?
Of course I have. But I'm a non-confrontational person and, again, I'm tactical.
I understand that it's got nothing to do with me. Sometimes it's got something to do with the fact that they hate how their hair was done but that's what the bride wanted. Or the bride asked for me to help her with their dress in the bathroom, and the Maid of Honour will say, "No, I should be doing that."
It's nature, and it's totally fine by me.

Of course, but a good bridesmaid never complains about her dress and always does what she's told.
It's just the way it is, but the good friends go, "I'm doing this for you."
What is the most unusual thing that you've been asked to do?
Oh, there's so many. During weddings in the bush, many times I've cleaned poo off brides' shoes with baby wipes when they've trodden in deer or horse poo while they're out taking photos.
How often do you work with a bride that you don't get along with?
I don't find there's really anyone I don't get along with. But there have been times where people have surprised me, because weddings can be a stressful situation. Sometimes they're totally cool as a cucumber during the lead up until the day of, and then it's as though it's the end of the world.
What's the one tip you'd give to all bridesmaids out there?
Remember who's wedding it is. And the bride's decision is final.
Don't complain about your dress if you can, particularly if the bride and groom are paying for those things.

The Faculty A review by Joe Chamberlain
Starring Elijah Wood; Jordana Brewster; Clea Duvall; Laura Harris & Josh Hartnett When I went into The Faculty I was expecting a typical teen horror flick. I figured it may be a bit above average considering that Kevin Williamson (Scream, Scream 2) had written the screenplay. My theory was that if Williamson was involved, at the very least this movie was going to be entertaining. Not only was the movie entertaining, but Williamson has proven once again that he is one of the most gifted writers in Hollywood. Add to that Robert Rodriguez' great job in the director's chair and you have the makings of a pretty good film. When you throw in a great young cast, you have a winner.
Elijah Wood plays the school whipping post, who works at the school newspaper with the head cheerleader (Jordana Brewster). In the course of looking for leads for a new story, they discover an even bigger one. Their teachers have been taken over by aliens, which are rapidly taking over the rest of the school. It then falls to them and four of their classmates, the only six people left in the school unaffected, to find a way to stop the aliens before they can take over the world. OK, it sounds a little corny, but it actually comes off pretty well. There is never any real point at which you start saying to yourself "As if that would happen". Of course, you have to get by the whole alien invasion thing. After gettting passed that, you are home free.
In terms of casting, The Faculty is fairly impressive. To make up for the relatively unknown, but extremely talented cast of high school students, the producers decided to cast some familiar faces in the roles of the faculty. They include Robert Patrick (the liquid terminator in Terminator 2), the high school principal is Bebe Neuwirth (Cheers), and the school nurse is Salma Hayek. (I'm betting every guy in that school gets sick at least once a week.) If Salma weren't enough, adding to the babe factor is Famke Janssen (Goldeneye). Among the young cast of students is only a couple of recognizable names, they are Josh Hartnett (who played Jamie Lee Curtis' son in Halloween: H20) and Elijah Wood (Free Willie). Singer Usher also makes a brief appearance in a small role. Adding some heat to the younger generation are up a coming hotties Jordana Brewster and Laura Harris. I enjoyed the performances of the whole cast. Of course, this is a horror movie and not Shakespeare, so nobody was really stretching their acting talents to the limit. As horror movie casts go, this one was fun to watch.
Unlike the early slasher type films of the late seventies and eighties, The Faculty actually had a production budget and it shows. This film wasn't shot on any shoestring budget, nor where the special effects cooked up in somebody's garage. The Faculty lives up to the high production values that were set by Scream a few years ago. So it's no coincidence that Kevin Williamson was involved in both films. Maybe it even raises the bar a bit. Considering that this was a movie about aliens, visual effects are a little more important.
It's a great movie. Although, parents should be warned -- The Faculty is not for the kids, even though it seems to be marketed towards them.

After being sentenced with felony theft, I got the rather unenjoyable experience of spending 3 months in county jail. Considering that this was my first time in jail, I was very scared and had no idea what to expect. I went in there with my presciptions of Lexapro and Adderall, and realized that the Adderall really sucked to take in jail, so I found some 'speed freaks' who had access to 'sleeping pills'.
Well, all I really wanted to do was sleep, considering this was the quickest way to blow time and get out quicker. So, I would trade my 20mg adderall for 100 to 400 mg's or Seroquel (or what they called it, 'Quil'). I was told it was a form of tranquilizer, hence the 'quil' in the name Seroquel.
Well anyways, around 10 am, I'd pop one of the pills, sometimes cutting them in half to sleep off of 50 mg, and sleep FOREVER! I don't even know if these pills are used as sleep aides, but it worked. Perhaps it was just the power of suggestion, but I didn't care, cause they conked me OUT! I'd wake up around 5 pm, then pop another one before bed time (around 10pm).
One weird side effect that I noticed was that, obviously, the more I took, the deeper I would fall into sleep. But the weird thing was, I would have very vivid dreams, and would actually yell obscenities in my sleep (definitely not a good thing to do in jail).  I actually had a guy come up to me and tell me that I was 'possessed' and should seek Jesus (I was actually attending a private Bible College the year before, so I'm pretty sure I wasn't possessed).
Generally if I only took 50mg, I'd be fine, but anything over 100 mg and I'd start yellin. But then, the nurses began to crush up the sleeping pills (Seroquel and Tradnizone), and stopped giving me my adderall. They had no idea that I was trading them for these pills, but the jail doctor stated 'It's an amphetamine, he shouldn't be taking it'. The jail doctor was a dumbass, I was diagnosed with ADD about a year before, and the pills had absolutley no amphetamine effect on me at all.

Get your kicks on route localhost:4567
I learned something about Sinatra today.
A route has three ingredients: an HTTP method, a URL matching pattern, and a code block. Typically they look like this:
get '/' do
"hello world"
end
But they can also look like this:
post '/game/:guess' do
game.guess(params[:guess])
end
private
def game
@game ||= Mastermind::Game.new_with_code(params[:code])
end
The code block returns information. That information can be anything, from a plain string (first example), or an html web page, to a JSON representation of an object (second example). What the browser does with the information it receives is the browser’s business.
I learned something about Ajax today.
An ajax call is built up from a few minimum parameters: a url, the HTTP method, the dataType expected, and a callback function that handles the return. You can include data from the user in the form of a data hash:
1 var the_url = "http://" + window.location.host + "/game/" + guess_string;
2 var mark_string = $.ajax({
3 type: "POST",
4 url: the_url,
5 accepts: "application/json",
6 dataType: "json",
7 data: { 'code' : secret_code },
8 complete: function(data){
9 output_mark = data['responseText'];
10 process_output(secret_code, guess_string, output_mark);
11 }
12 });
This code snippet is using Ajax to send the secret code and guess to the Sinatra route . The route does its magic, and returns a json containing the result.
The overall workflow:
- The url on my local machine looks like this: “http://localhost:4567/game/12345” (line 1). The submitted guess is 12345.
- Ajax packages the url with the data hash containing the secret code (line 7).
- Javascript submits the HTTP POST request to Sinatra which matches the route.
- The route creates a Mastermind::Game object with the provided secret code.
- The route calls the guess method on the Game object with the submitted guess.
- The route returns a json of the method output (in this case it is a string of +/- characters indicating exact number matches(+) or matched numbers in the wrong position(-)).
- In the ajax callback function the data from the json object is parsed and passed on for further processing.
I learned something about routes today.
I had a mental block about routes. I thought that building the “/game/:guess” route in Sinatra meant that the user would be constantly navigating between “/mastermind” and “/game/:guess”, and that the game would always be reloading with a new secret. I was thinking about routes the wrong way – when javascript calls the route, it doesn’t reload the page, it just retrieves data! I had conflated routes with navigation in my imagination, and forgot that a route is just a method call containing a request for information. Just because the information returned is often rendered as an html page doesn’t mean that it has to be html. Which leads me to the penultimate point…
I learned something about curl today.
ANYTHING can make an HTTP request. Ok, maybe that is a slight overstatement.
Browsers interpret the information retrieved using HTTP requests, but they are far from the only category of software that can. Turns out, the command-line functions just as well:
1 $ curl -X POST -H "Accept: application/json" -d "code=12345" js-games.herokuapp.com/12345
2 +++++$
The command on line 1 will return the same string I am retrieving with $.ajax in javascript (output on line2). Sure it is a fairly plain result – it doesn’t even include a new line character, for pity’s sake – but it does the job of making an HTTP request to a route and using the result.
I learned something about myself today.
I didn’t even realize I was misunderstanding HTTP! It was one of those concepts I had already checked off my mental list of technologies to cover on my quest to become a web developer. This breakthrough has reminded me that reviewing the fundamentals in the context of learning new technologies will bring a deeper understanding of everything.
Awesome

Real quick, so we're all talking about the same thing, a few definitions:
Styles = Refers to CSS. There's 3 possbilities: CSS, CSS Compiled, and SCSS
CSS
= The styles of a website. Accessed via a .css file. It's basically a set of instructions for a browser, telling it how to display the markup (HTML).
SCSS
= Otherwise referred to as Sass. Sass is a pre-processor, meaning it operates before a website would be using the styles. It outputs to a .css file, which is what the browser actually uses to genreate the styles.
Sass breaks up vanilla CSS into managable, highly customizable and extendable chunks, such as:
_topnav.scss
, _footer.scss
, etc.)$slate
, $topnavHeight
),@include hover(){color: $hoverColor}
) then compiles them into one master styles.css
file.CSS
Pre-Compiled = When developing CSS, it's written in a more readable, expanded format. Like so:
.style {
display: block;
margin: 0 1rem;
}
.styleTwo {
background: $slate;
color: $wht;
}
.styleThree {
padding: 1rem;
color: $wht;
}
CSS
Compiled = In order minimize load time, css is compiled down to remove extra spaces in order to save filesize. This is what the file SCSS files compress down into. It's not intended to be used during developing the styles, because it's nearly unreadable.
.style{display:block;margin:0 16px} .styleTwo{background:#404040;color:#fafafa} .styleThree{padding:16px;color:#fafafa}
Markup = refers to the HTML.

Card

Semantics = When writing markup (HTML), writing semantic code means using meaningful code tags (
,

,
, etc.) that describe their function, instead of using non-descript, meaningless containers (

and (
).
Note, this isn't to say you can't ever use div
s or span
s, but if there's a more meaningful tag, you should use it.
Responsive Web Design = Given the massive variety of devices, screen sizes, operating systems, and browsers, it's better to build the website to adapt it's styles based on the screensize (via breakpoints), rather than forcing the users to access the site in specific way ("This site will only run on IE8" shudder ).
Accessability = Hand-in-hand with the concept of a Responsive website, in additon to a variety of a11y coding best practices), by coding semanticly we can ensure the site is truly responsive, and all of its content can be viewed and accessed through navigation by everyone, whether via mobile touch-screen, a mouse, a keyboard, a screenreader, or any other method. (for more on this, check out A11y For The Masses )
-Style Asset Library
= The scss files from PA.Gov, and the js plugin, What-Input.

To start learning postgresql, I analyzed the inspection records of the restaurants in New York.
(https://s3.amazonaws.com/thedataincubator/coursedata/nyc_inspection_data.zip)
The data was a bit messy with some unnecessary href tags so I used python to remove these and clean up the data a little bit. I’ll spare the details but the code is here.
The main file is Webextract.txt which contains the record of all inspections of NYC restaurants from around 2009 to 2014 (though according to the data there are some inspections from 1900?).
Let’s take a look at the first few entries of the inspection table.
I am mostly interested in the scores. I want to look at different groupings of restaurants and extract the best and worst restaurant scores. First of all, the higher the score the worse the restaurant did in the inspection - the score keeps track of the number of violations. Notice also that cuisinecode and violcode are just 2-3 character strings. To interpret them we will need the lookup tables Cuisine.txt and Violation.txt. I definitely see a use for sql joins in the near future!
As I said, I will be using postgresql to analyze this data set. The full sql code is available here.
Scores by Zipcode
To start I wanted to know something about the mean grade in the different zipcodes of new york and who was doing the worst:
-- compute the mean, standard error of the scores in each zipcode
-- order by top scores
CREATE TABLE topscores
AS
SELECT
zipcode,
avg(score) as mean,
stddev(score)/sqrt(count(score)) as std
FROM grades
GROUP BY zipcode
HAVING count(score) > 100
ORDER BY mean DESC;
I checked the worst scoring zipcode and it's Flushing, NY. I've never been there and now it's slightly lower on my to do list.
Obviously I'm also interested to see which zipcodes have the best scores and how much better those grades are.
I looked up the top zipcode - this is the neighbourhood right around Rockefeller Center. Probably a lot of volume down there so things need to be kept fairly clean. Also the 10 point difference seems pretty significant.
By Cuisine Type
Now let’s look at cuisine types. I want to see what the average scores are of different cuisine types. Notice the join we need to do with the cuisine lookup table to get a descriptive string of the cuisine type.
CREATE TABLE cuisinescores
as
SELECT
codedesc,
avg(score) as mean,
stddev(score)/sqrt(count(score)) as stderr,
count(score) as numinspect
FROM grades inner join cuisine
using (cuisinecode)
GROUP BY codedesc
order by mean DESC;
And of course we need to look at the flip side of this. Which cuisine types are not keeping such clean establishments?
So at first glance, it seems that the simpler the food prep is the better the inspection score. Probably could have guessed that but it’s nice to see it in the data. One outlier here is Ethiopian food. I don’t think the food prep there is that simple but it scores quite well.
As a side note, I’m curious how prevalent a type of restaurant has to be to break out of regional categorization. I’m thinking African versus Ethiopian. And I also noticed that there is no subcategory for sushi restaurants. Seems like they’re all considered Japanese restaurants.
Disproportionate violations per cuisine code
The next question I try to answer is which cuisines have a disproportionate number of which violations. Notice that more prevalent cuisine categories will have more violations because there are more such restaurants. And there are also more common types of violations across all cuisine types.
To to take of this normalization issue we look at the conditional probability of a particular violation given a cuisine code normalized (divided by) the probability of that violation over the whole data set.
Just to make things more complicated the violation codes change over time. As an example ‘01D’ could mean “Current valid food vendor license not available” or “Failure to comply with an Order of the Board Commissioner or Department” depending on the date of inspection. To take care of that we first do a join with the violation table and then keep only the violation descriptions which were valid on the date of inspection.
 We need a count of the total number of violations, violations per cuisine code, violations per violation code, and violations per cuisine code, violation code (number of particular violations of a cuisine code). And I’m sure that will be a lot clearer in the sql below!
CREATE TABLE viol_counts
as
SELECT cuisinecode, violationdesc, viol_c, viol_v, viol_v_c,
(sum(viol_v_c) over()) as viol_total
FROM
(SELECT
cuisinecode,
violationdesc,
count(*) as viol_v_c
FROM grade_viol_descript
GROUP BY cuisinecode, violationdesc
)as viols_v_c
join
(SELECT
cuisinecode,
count(*) as viol_c
FROM grade_viol_descript
GROUP BY cuisinecode
) as viols_c
using(cuisinecode)
join
(SELECT
violationdesc,
count(*) as viol_v
FROM grade_viol_descript
GROUP BY violationdesc
) as viols_v
using(violationdesc);
Now we can use the counts to get the probabilities of all the different violation configurations and from that calculate the ratio we are interested in. This ratio is skewed when the number of violations of a the particular cuisine is small or when the count of the particular violation is small. To avoid this we select out only those points with more than 100 violations of a certain cuisine code and particular violation.
CREATE TABLE viol_probs
AS
SELECT
violationdesc,
cuisinecode,
viol_c,
viol_v,
viol_v_c,
p_v_c,
p_v,
p_v_c/p_v as ratio
FROM
(
SELECT violationdesc,
cuisinecode,
(cast(viol_v_c as float))/viol_c as p_v_c,
viol_v/viol_total as p_v,
viol_c,
viol_v,
viol_v_c
FROM
viol_counts
where viol_v_c > 100
) as pre_viol_prob;
As I said earlier, there is no category for sushi restaurants. And so Japanese encompasses a lot of sushi restaurants which I guess do not handle raw (sea) food in a way that makes health inspectors very happy. The issue of not holding food certificates and posters not being placed properly for is slightly interesting but probably misleading here. I should be selecting out ‘significant’ inspection violation. The other thing to notice is that cooling and heating food are the main issues rounding out the top ten. This makes a lot of sense to me. When food is being served to customers time is an issue and it takes time and organization to thaw and cool food properly.
Final thoughts
I didn’t love working in postgresql. I did the same analysis in pandas and it felt much cleaner with much more exploratory freedom. In particular setting up the tables in sql was a real pain. There were lots of encoding errors and incorrect data types and fixing these errors was somewhat laborious mostly because it took a lot of trial and error to figure out what was wrong. Of course it was a bit nonsensical to use sql in this analysis because these data sets will actually load in memory. I definitely see the use of working with sql when the data sets are much bigger and I have developed a bit of a feel for the syntax so all around I’d say this was a worthwhile exercise for me.

Latin-Square Geometry:
Orthogonal Latin Squares as Skew Lines
-- From Error-Correcting Codes
Through Sphere Packings
To Simple Groups,
by Thomas M. Thompson,
Mathematical Association of America, 1983
"Packing finite projective spaces with disjoint subspaces has for many years been a topic of considerable interest in Galois Geometry. In particular, one studies partial spreads in a space PG(3,q), that is, collections of pairwise disjoint lines in PG(3,q): see Hirschfeld [8] for background. A set of r mutually skew lines for which any other line meets at least one line of the set will be referred to as a maximal partial spread (MPS) of size r.
An interesting combinatorial problem (which seems at first sight not at all related to partial spreads) is the determination of the pairs (s,t) for which a maximal set of t mutually orthogonal Latin squares of order s exist...."
-- Some new maximal sets of mutually orthogonal Latin squares,
Keywords: latin squares, MAXMOLS, partial spread, projective space, polar space
by P. Govaerts, D. Jungnickel, L. Storme, and J. A. Thas,
Designs, Codes, and Cryptography
29 (1-3), May-June-July 2003, pp. 141-147Mathematics Subject Classification: 05B15, 05B25, 05B40
These authors said, in early 2003, that spreads and orthogonal Latin squares seem "at first sight" unrelated. They of course did not mention my note (shown below) that pointed out such a relationship in December 1978. The earliest sources they cited for such a relationship are Jungnickel in 1984 and 1993.
Here are the details of my 1978 note.
We present two results -- one old, one new -- on the
geometry of Latin squares.
Result A (old):There exist n-1 mutually orthogonal nxn Latin squares if and only if there exists a finite projective plane with n2 + n + 1 lines (or, equivalently, an affine plane with n2 + n lines).Result A is well known. See, for instance, chapter 8 of Discrete Mathematics Using Latin Squares, C. F. Laywine and G. L. Mullen, Wiley Interscience, 1998, or Bose's [1938] Theorem (pdf). Result B (new):The six 4x4 Latin squares that have orthogonal Latin mates can be embedded in a set of thirty-five 4x4 arrays so that orthogonality in the set of arrays corresponds to skewness in the set of 35 lines of the finite projective space PG(3,2).Result B is apparently new, and should not be confused with result A. The closest thing to the diagrams of result B in the refereed literature seems to be the use of diagrams on page 774 of Design Theory, Volume 2, by T. Beth, D. Jungnickel, and H. Lenz, Cambridge U. Press, 1999, in proving Tarry's theorem on the nonexistence of two mutually orthogonal 6x6 Latin squares. The research note below shows how result B works. Note particularly that the 35-line projective space of result B differs from the 21-line projective plane of result A. Result B is, of course, highly special, being limited to 4x4 squares. This limitation should not prevent its use as an example in popular introductions to discrete mathematics. Indeed, the 4x4 case figured prominently (and exclusively) on the cover and in a two-page article in the August/September 2001 issue of the Mathematical Association of America's "Focus" newsletter. Naturally, a more general result than B is desirable; hence the problem stated in the 1978 research note below. Steven H. Cullinane
Orthogonality of Latin squares viewed as skewness of
lines. Dec. 1978.
Shown below is a way to embed the six order-4 Latin squares
that have orthogonal Latin mates in a set of 35 arrays so that
orthogonality in the set of arrays corresponds to skewness in the set
of 35 lines of PG(3,2). Each array yields a 3-set of diagrams
that show the lines separating complementary 2-subsets of
{0,1,2,3}; each diagram is the symmetric difference of the other
two. The 3-sets of diagrams correspond to the lines of
PG(3,2). Two arrays
are orthogonal iff their 3-sets of diagrams are disjoint, i.e. iff the
corresponding lines
of PG(3,2) are skew.
This is a new way of viewing orthogonality of
Latin squares, quite different from their relationship to projective
planes.
PROBLEM: To what extent can this result be
generalized?

The apparent conflict between the 2003 paper by Jungnickel et al. and my 1978 note can be resolved as follows:
"The [1954-1964] André/Bruck-Bose construction yields a one-to-one correspondence between spreads of projective space and translation planes (special affine planes). If one feeds a partial spread into this construction, a net results. A net is a point-line geometry which is a natural weakening of an affine plane."
-- John Bamberg, Symplectic spreads
And it has long been known that affine planes are, as noted above, closely related to orthogonal Latin squares.
In other words, the 1954-1964 André/Bruck-Bose construction is the missing (missing, that is, according to Jungnickel, Thas, et al.) link between Latin-square orthogonality and projective-space skewness. Such an orthogonality-skewness link is shown rather more directly and clearly in my 1978 note.

For further background, here is material on finite geometry from the paper Symplectic spreads (pdf), 15 Sept. 2003, by Simeon Ball, John Bamberg, Michel Lavrauw, and Tim Penttila:
From Symplectic spreads (pdf):"First we give an overview of some definitions and theory of finite geometry, together with some results of the past which provide the context and background for our construction. A projective plane is an incidence structure of points and lines such that: (PP1) for every pair of distinct points there is a unique line which is incident with both of them; (PP2) every pair of distinct lines meet in a unique point; (PP3) there exist four distinct points with no three collinear (no three are incident with a common line). An affine plane is an incidence structure of points and lines such that: (AP1) for every pair of distinct points there is a unique line which is incident with both of them; (AP2) for any non-incident point-line pair p, L, there exists a unique line through p which has no point in common with L; (AP3) there exist three non-collinear points. In a projective or affine plane, a point P is a centre for a collineation phi if phi fixes every line incident with P. A line l is an axis of phi if phi fixes every point on l. It is standard knowledge that every non-identity collineation has at most one axis and at most one centre, and it has an axis if and only if it has a centre (see [7, Section 3.1.4]). A collineation which has a centre and axis which are incident with one another, is called an elation. A group of collineations H is called (P, l)-transitive if the subgroup of H consisting of those elements which have centre P and axis l, acts transitively on the non-fixed points of any line through P which is not equal to l. For two lines m and l, we say that H is (m, l)-transitive if H is (P, l)-transitive for all P on m. Dually, if P and Q are points, then we say that H is (P, Q)-transitive if H is (P, l)-transitive for every line l incident with Q. Let Gamma be a projective plane and suppose that Delta is an affine plane obtained by removing the line linfinity from Gamma. Then Delta is a translation plane if there exists a

new maximal sets of "Let us briefly sketch the connection between partial spreads in PG(3,q) and sets of mutually orthogonal Latin squares of order q2. Any r mutually skew lines in PG(3,q) may be viewed as a collection of r pairwise disjoint subgroups of order q2 in the additive group of the vector space V = V(4,q) (meaning, of course, that any two of these subgroups intersect trivially). This is a particular example of a so-called partial congruence partition (PCP) and therefore leads to a (translation) net of order s = q2 and degree r by taking the vectors in V as points and all the translates of the specified r subgroups as lines, cf. [9] or [2]. If the given partial spread is actually maximal, one may hope that the associated net is likewise maximal, resulting in t = r - 2 MAXMOLS(s), s = q2. This approach has been used successfully by Jungnickel [10, 11]. However, in general, the associated net may well be extendable; it is easily seen that this happens if and only if the net admits a transversal, i.e., a set of s points meeting every line of the net in a unique point. In the present note, we will use maximal partial spreads of size r in PG(3,4)\PG(3,2) to construct transversal-free translation nets of degree r + 3; this approach will give our new examples of MAXMOLS(16)."

For the use of the term "partial spreads" to mean sets of affine
parallel classes (as interpreted within graph theory), see
Partial spreads (ps),
a note by Chris Godsil:
"Let Z be a complete graph on n2 vertices. A parallel
class in Z is a spanning subgraph isomorphic to nKn.
We say two parallel classes S1 and S2
are orthogonal if they have no edges in common....
A partial spread is a set of pairwise orthogonal parallel
classes."
This informal note has no references. The way the note uses the
terms "partial spread" and "orthogonal" is directly related to my 1978
note. Historians of mathematics can determine whether Godsil is
the first to use these terms with these meanings.
