What do you think about being dumb?


I was one of three front-end developers working to bring Marc Jacobs' desktop and mobile site redesign to life. I built World of Marc Jacobs, the checkout process, many of the MyMJ pages, and worked on many other site areas and features.

A team-oriented aerospace engineer driven to improve air and space systems through autonomy and robotics.
Since August, I have enacted both software and hardware changes to multiple unmanned vehicles under the guidance of my advisor, Dr. Eric Johnson.
I outfitted a commercially-available hobby-level fixed wing with electronics necessary for unmanned flight. This included receiver and flight controller setup using open-source flight control software, as well as a wireless communications link for use with a ground station for remote monitoring and commanding of autonomous waypoints.
Additionally, I have developed our own fork of the open-source Betaflight flight control software for multirotor autonomous flight. The fork includes additions of serial read and write commands for sending IMU readings and pilot input data, and auto/manual logic for switching between automatic and manual flight.
To see all the work happening at PURL, check out the lab website.
As an undergraduate, I looked to place myself as quickly as possible into a position where I could experience a professional engineering environment.
As a fresh intern, I spent my first summer becoming familiar with first responders and their missions, problems, and ideas for new technology. This research culminated in my first publication: The Next-Generation Firefighter: The Evolution of Technology.
During the rest of my tenure at NIST, I created technology that would demonstrate potential improvements to the current technology used by first responders. To accomplish this, I created a Lego model of the physical layer of LTE (cellular) downlink to show first responders just how much more advanced LTE is when compared with traditional Land Mobile Radio (LMR). Additionally, I implemented an HTML dashboard which was utilized to display the location and vital statistics of a first responder equipped with a sensor harness to monitor their health.
Advisor: Dr. Eric N. Johnson
GPA: 3.46
For me, the choice to attend grad school was simple. Undergrad did a great job of exposing me to all sub-disciplines within aerospace engineering, but left me wanting when it came to improving the depth of my knowledge in areas that especially interested me. By the time senior year came around, I wanted to know more about dynamics and control systems before entering the workforce. If anything, grad school has shown me that there is more to learn than I can possibly imagine, so I look forward to learning as much as possible in the workplace.
As a graduate student, you are responsible for interacting with department faculty much more often than as an undergrad. In this role, I've had the opportunity to become much more familiar with the inner workings of academia, and by extension, the industry that sponsors adademic research projects.
My thesis topic has to do with quadrotor vehicle performance when station keeping over a ship. I have begun work on this topic already by submitting a conference paper to be presented at SciTech 2020 in Orlando.
The foundation of my knowledge of aerospace engineering is all thanks to the University of Colorado. As a lowly high schooler excited to make cool planes and spaceships, CU taught me statics, dynamics, control systems, heat transfer, aerodynamics, vehicle design, and propulsion: the academic basis that is so fundamental in the aerospace industry. In addition to the academics, though, CU involved all students in labs for each course which encouraged students to work quickly and efficiently in teams to complete assignments on time.
Both the academic and realistic skills I learned at CU make me feel confident that I can work with teams to solve complex problems and come up with robust and novel solutions in a professional setting.
Beyond aerospace engineering, I like to pursue many hobbies which I maintain with varying levels of consistency.
 If these sound interesting to you, be sure to check out my Medium webpage where I like to create data-driven write-ups of my interests.
To scratch my itch of building drones, I am a member of the Penn State Autonomous Robotics Competition Club, which competes around the world (United States and Spain so far) in aerial robotics competitions. Along with my teammates, I've had the opportunity to play around with hobbiest hardware like Pixhawks, Flamewheels, and Raspberry Pis. The club has encouraged me to become more familiar with parts of a system that I wouldn't usually be exposed to, like WiFi communication and Python programming.
When I'm outside, I've spent most of my recent time mountain biking in the Rothrock State Forest just South of State College. When I lived in Colorado, I really enjoyed skiing with my friends and wife. I've always been passionate about not relying on a car to commute to either work or school, so when I lived in Boulder I would either ride my bicycle or take the bus. Now that I live in Pennsylvania, I have improved my efficiency and speed by switching to an electric bicycle (the Rad Rover) to commute to both work and school (2100 miles and counting!).

Feeling the feedback
Pairing and the social side of DBC
March 8th, 2015
Pairing with another person to solve challenges was... interesting. For most of my life I've been a solo programmer, and frankly, there are some things that I really enjoy about pair programming, and some things that really wear on my during my pairing sessions.
The fun parts of pairing were finding solutions we were stuck on before, or finding a neat hack to show the other person. There are definitely some real benefits to pair programming, and I would say that for the most part, I benefited from having someone else to bounce ideas off of and spot bugs with my code.
However, there are some really frustrating parts of pair programming for me. Namely, I feel that the driving and navigating roles can sometimes be very restricting, and the match up of skill can be problematic. Many times while pairing, I felt like I had a potential solution, but couldn't quite describe it to the driver, (a reflection on my own skill, of course.) or felt like I couldn't just go ahead and try it without the navigator's go ahead. Furthermore, I enjoy teaching others, so having a new trick to show someone is always nice, but when it's the other way around and I'm the one behind, I feel very much like a burden, and it takes a lot of the fun out of it for me.
Reading my feedback made me feel quite good about myself. Knowing that I'm doing a good job is comforting. For the most part, my feedback didn't contain anything major that I had to work on, so I suppose the lesson that I'm taking from it is to keep doing what I'm doing for the most part.
One of the biggest places that I can improve in as far as my pairing sessions go is being more assertive while driving. There have been several times where I've had a potential solution, and I've held back on saying it because I didn't feel like it was my place to interject. One of the people that I paired with picked up on this, and recommended that I embrace my assertive side, as long as I continue to be polite.
Writing feedback was probably one of the harder things I've had to do at DBC, because I've had to fight the urge to sugar coat things every step of the way. Going hand in hand with this though is the problem that I have finding things in need of feedback in the first place. Most times, I am completely satisfied with my pairing sessions, which leaves me little or no actionable pieces of advice to give.
Overall, I think the pairing and feedback system is a worthwhile way of learning. When you and your pair are stuck on something, it's easy to forget that learning to code is not the sole purpose of the pairing sessions, and that learning how to interact with people in preparation for the workplace is a major part of pairing.

Analysis of 3 Sites
This is an analysis of three of my favorite websites.
The first site I will look at is Hacker News. I like this site because it has a lot of news on technical items on a wide range of topics. Visually there is not much to it. At the top is the header/logo with some simple navigation and below that is the list of articles from other sites. The articles have a title and some minor information and you pretty much just click any story that sounds interesting and you are take to that site to read it. This makes the site simple and practicle, almost spartan, but that is also it's strength, as there isn't anything to distract you. If you are looking for something specific, you can use the search box at the bottom of the page. You can browse by clicking "More" which pages you into older content. It's all very simple.
The next site is Amazon. I like this site, as it is sort of a one stop for all shopping. When you arrive on the site, you are visually drawn to the center of the page where the current specials stand out prominantly. But the power of the site is found above in the search box, when you can search for just about anything you can think of to buy. The site is bright and colorful and gives a happy and comfortable feeling. If you wish to browse the content there is navigation on the side to allow you to drill down into categories of products. You can spend a lot of time here browsing and seeing what the site suggests to you.
The third site is the BBC. I like this site for it coverage of world news from a perspective that is not biased by US politics. When you arrive at the site the most prominant feature is the large rotating images of top stories. Below that are what are lesser stories, grouped by category. Visually there is a lot to this site, but the images are set up in a distinct hierarchy so you are visually guided from most important to least important. The site feel both informative and entertaining, and the BBC name brings a level of trust. to find something specific, you can use the search box at the top ot the page where the category navigation is also useful for browsing the site.

Exclusive: Alibaba planning launch of US$15 billion HK listing for last week of November - sources
Alibaba Group Holding Ltd plans to launch a Hong Kong share offering to raise US$10 billion to US$15 billion in the final week of November, two people with direct knowledge of the matter told Reuters.
REUTERS: Alibaba Group Holding Ltd plans to launch a Hong Kong share offering to raise US$10 billion to US$15 billion in the final week of November, two people with direct knowledge of the matter told Reuters.
The U.S.-listed Chinese e-commerce giant is due to seek approval from Hong Kong's listing committee on Thursday, the people said, for a deal that Dealogic data showed will be the world's biggest-ever cross-border secondary listing.
The people declined to be identified due to the sensitivity of the matter. Alibaba did not immediately respond to a request for comment.

Preparation time
less than 30 mins
Cooking time
30 mins to 1 hour
Serves

The beauty of this dish is that you can substitute or add whatever you like. It's a great way to use up what's in your kitchen. A simple version of a well-loved dish.
Heat the olive oil in a large pan and add the onion, mixed peppers, garlic, chorizo and chicken pieces. Cook for about ten minutes.
Add the chilli peppers. These are very hot so be careful how many you add. When handling them, take care if you have any cuts as they will really hurt.
Add the rice and stir well. Add the chilli powder, turmeric and Cajun spices and mix in so the rice is well coated with the flavours.
Add the chicken stock or water and bring to a simmer.
Add the mixed vegetables and bring to the boil then turn the heat down to a simmer.
Once the rice has swollen and is part-cooked, add the prawns or crayfish.
Simmer for about 45 minutes to an hour. Taste for seasoning and add salt and freshly ground black pepper and more spices, depending on your personal taste.
Serve.

maestro
: a pool of pools for when single pool managers become a bottleneck.
Big worker pools for short-lived I/O tasks (e.g. database access) can easily overrun a single poolboy
manager due to too much check-in / check-out activity.
Take the naïve approach and launch multiple pools; pick them at random when checking out. Having maestro
be aware of each pool workload would be nice but it would increase complexity and lower performance without any significant advantages when all the pools are already under a similar load pattern.

Problem Description
We can call two numbers “similar” if their lengths are equal and we can make a number ‘’similar’’ through swapping some digits of itself. For instance, 123 is similar to 321 but 12 is not similar to 120.
A sequence can be called “similar sequence” if this sequence has only one pair of ‘’similar’’ numbers.
Now, Zero writes a series of integers and he needs you to answer his queries online. For each query, he gives you two integers l and r, which represent the two endpoints of a segment. He wants to know how many successive subsequences are “similar sequences”.
A sequence can be called “similar sequence” if this sequence has only one pair of ‘’similar’’ numbers.
Now, Zero writes a series of integers and he needs you to answer his queries online. For each query, he gives you two integers l and r, which represent the two endpoints of a segment. He wants to know how many successive subsequences are “similar sequences”.
Input
There are multiple test cases.
In the first line of every test case there are two integers n (0<n<=100000) and m (0<=m<=100000), meaning that the sequence contains n integers and m queries.
The next line contains n integers a[i] (1<=i<=n, a[i] <= 109), which represent the integers in the sequence.
After that, there are m lines, each line containing two integers l and r.
Zero thinks that it is too simple for him to solve this problem, so he sets a variable k. In the beginning of each test case, k = 0. For each query, he sets l = l + k and r = r – k, Zero guarantees that 0<l<=r<=n, then make k the answer of this query.
The input ends with EOF.

Output
For each query, output an integer, and there is no blank line after each test.

题意：定义相似数为两个数的数字组合相同，相似区间为这个区间内有且仅有一对相似数。给定l和r，求共有多少个相似区间。
思路：参考http://blog.csdn.net/acm_cxlove/article/details/8931000,大概就是求出区间内相似对数>=1的，和>=2的，然后做差，剩余的就是你=1的
AC代码如下：
#include<cstdio> #include<cstring> #include<map> #include<string> #include<algorithm> using namespace std; typedef long long ll; map<string,int> match; char s[100010][20]; int n,m,point[100010],one[100010],two[100010],sum_one[100010],sum_two[100010]; bool cmp(char a,char b) { return a<b; } int main() { int i,j,k,a,b,len,c,pos; ll l,r,ans; while(~scanf("%d%d",&n,&m)) { for(i=1;i<=n;i++) scanf("%s",s[i]); match.clear(); for(i=n;i>=1;i--) { len=strlen(s[i]); sort(s[i],s[i]+len,cmp); k=match[s[i]]; if(k==0) point[i]=n+1; else point[i]=k; match[s[i]]=i; } a=n+1;b=n+1; for(i=n;i>=1;i--) { c=point[i]; if(c<a) b=a,a=c; else if(c<b) b=c; one[i]=a; two[i]=b; } for(i=1;i<=n;i++) { sum_one[i]=sum_one[i-1]+(one[i]-1); sum_two[i]=sum_two[i-1]+(two[i]-1); } ans=0; while(m--) { scanf("%I64d%I64d",&l,&r); l+=ans; r-=ans; ans=0; pos=upper_bound(one+1,one+n,r)-one-1; if(pos>=l) ans+=r*(pos-l+1)-(sum_one[pos]-sum_one[l-1]); pos=upper_bound(two+1,two+n,r)-two-1; if(pos>=l) ans-=r*(pos-l+1)-(sum_two[pos]-sum_two[l-1]); printf("%I64d\n",ans); } } }

The Series
Darkside came into the post-season with dissappointing losses in all the regular season tournaments they played in.
Regionals
Darkside cruised through pool play and into the finals of regionals to earn a matchup against their rival: UNC Wilmington. Darkside stomped Wilmington, prevailing with a 15–7 victory.
Darkside now looked completely different from the team that did not win a single regular season tournament as they headed to Milwaukee as the #3 overall seed.
Nationals
Darkside carried their momentum from regionals into pool play on Friday with wins over Florida State, Illinois, and Maryland. Their hard work meant that they locked up their pool, and got to rest in their game against Oregon.
Bracket play started off with a rematch of the 2014 finals against Colorado. Darkside came out strong and outplayed Colorado in a 15–9 victory to advance to the semi-finals where they played Central Florida. Both teams started out strong, but Darkside pulled away in the occasionally chippy game that ended in a 15–10 win to advance to the finals. The game was Darkside’s from the beginning as they cruised to a 15–6 victory against a totally outmatched Oregon team and clinched their first national title.


Interface NamingConvention
- All Known Implementing Classes:
AbstractNamingConvention
,MatchingNamingConvention
,UnderscoreNamingConvention
public interface NamingConvention
The main goal of the naming convention is to reduce the amount of configuration required in the mapping (especially when mapping between column and property names).
Note that if you do not define a NamingConvention the default one will be used and you can configure it's behaviour via properties.
-
Method Summary
Modifier and Type Method Description String
getColumnFromProperty(Class<?> beanClass, String propertyName)
Return the column name given the property name.String
getForeignKey(String prefix, String fkProperty)
Return the foreign key column given the local and foreign properties.TableName
getM2MJoinTableName(TableName lhsTable, TableName rhsTable)
Returns the ManyToMany join table name (aka the intersection table).String
getPropertyFromColumn(Class<?> beanClass, String dbColumnName)
Return the property name from the column name.String
getSequenceName(String tableName, String pkColumn)
Return the sequence name given the table name (for DB's that use sequences).TableName
getTableName(Class<?> beanClass)
Returns the table name for a given Class.boolean
isUseForeignKeyPrefix()
Return true if a prefix should be used building a foreign key name.void
loadFromProperties(PropertiesWrapper properties)
Load setting from properties.void
setDatabasePlatform(io.ebean.config.dbplatform.DatabasePlatform databasePlatform)
Set the associated DatabasePlaform.
-
Method Details
-
setDatabasePlatform
Set the associated DatabasePlaform.This is set after the DatabasePlatform has been associated.
The purpose of this is to enable NamingConvention to be able to support database platform specific configuration.
- Parameters:
databasePlatform
- the database platform
-
getTableName
Returns the table name for a given Class.This method is always called and should take into account @Table annotations etc. This means you can choose to override the settings defined by @Table if you wish.
- Parameters:
beanClass
- the bean class- Returns:
- the table name for the entity class
-
getM2MJoinTableName
Returns the ManyToMany join table name (aka the intersection table).- Parameters:
lhsTable
- the left hand side bean tablerhsTable
- the right hand side bean table- Returns:
- the many to many join table name
-
getColumnFromProperty
Return the column name given the property name.- Returns:
- the column name for a given property
-
getPropertyFromColumn
Return the property name from the column name.This is used to help mapping of raw SQL queries onto bean properties.
- Parameters:
beanClass
- the bean classdbColumnName
- the db column name- Returns:
- the property name from the column name
-
getSequenceName
Return the sequence name given the table name (for DB's that use sequences).Typically you might append "_seq" to the table name as an example.
- Parameters:
tableName
- the table name- Returns:
- the sequence name
-
isUseForeignKeyPrefix
boolean isUseForeignKeyPrefix()Return true if a prefix should be used building a foreign key name.This by default is true and this works well when the primary key column names are simply "id". In this case a prefix (such as "order" and "customer" etc) is added to the foreign key column producing "order_id" and "customer_id".
This should return false when your primary key columns are the same as the foreign key columns. For example, when the primary key columns are "order_id", "cust_id" etc ... and they are the same as the foreign key column names.
-
getForeignKey
Return the foreign key column given the local and foreign properties.- Parameters:
prefix
- the local column used to prefix the fk columnfkProperty
- the property name of the foreign key- Returns:
- the foreign key column
-
loadFromProperties

[dscrdeql] <Jellysmash> and growing new improved skin
[dscrdeql] <Jellysmash> like some animals do
[dscrdeql] <SwimedDragon> Are we using EQL or EQLI? It's hard to say which one because on exrates it's still EQL
[dscrdeql] <tipsy_dev == (auscoi)> EQLI
[dscrdeql] <tipsy_dev == (auscoi)> Just look at Tipsy's name
[dscrdeql] <tipsy_dev == (auscoi)>
[dscrdeql] <tipsy_dev == (auscoi)> constant reminder
[dscrdeql] <Biomech-Founder> Going forward, it will be EQLI. It was supposed to be at exrates, too, but they screwed it up
[dscrdeql] <SwimedDragon> Ok
[dscrdeql] <SwimedDragon> Are they planning on changing it?
[dscrdeql] <SwimedDragon> Or will they keep it as EQL?
[dscrdeql] <Cryptoon> isnt something like that done on a chain level?
[dscrdeql] <Biomech-Founder> No idea. We asked.
[dscrdeql] <Biomech-Founder> No, it's just a label.
[dscrdeql] <Biomech-Founder> For barterdex, yes, but that's because of the atomic swaps. On an exchange, they could call it 'bob' as long as it taks to the right daemon.
[dscrdeql] <SwimedDragon> Would be funny if that happened for a day
[dscrdeql] <SwimedDragon> Or is there already a bob coin out there?

[dscrdeql] <Biomech-Founder> I believe, but cannot prove, that some projects have a back door to CMC.
[dscrdeql] <Steve10> Agree about cmc
[dscrdeql] <Biomech-Founder> The requirements don't make sense to the coins listed.
[dscrdeql] <tipsy_dev == (auscoi)> I know for a fact one small coin I've been messing with has been trying forever to get on there and always rejected due to volume but recently got on after reapplying now that restrictions are lowered
[dscrdeql] <tipsy_dev == (auscoi)> and vol is still low lol
[dscrdeql] <Biomech-Founder> Hope you're right. Not my department. I'd probably piss 'em off

[dscrdeql] <c2k> its definitely a party in the other room. im getting dizzy trying to follow the action
[dscrdeql] <justincawa> do you get level points by talking in #off-topic or just in here?
[dscrdeql] <Cryptoon> @c2k been working a lot
[dscrdeql] <Cryptoon> working on an acquisition of my company and its daughter company
[dscrdeql] <Cryptoon> So yeah stressful and long days
[dscrdeql] <Cryptoon> Not that much time for crypto fooling around :p
[dscrdeql] <Cryptoon> also can't say that I liked seeing my level 50 rank get stripped away
[dscrdeql] <Cryptoon> probably rained over 3k or so in here so yea
[dscrdeql] <Cryptoon> That's no fun
[dscrdeql] <tipsy_dev == (auscoi)> @justincawa anywhere you see Tipsy in member list you get XP
[dscrdeql] <Buddz1993> Good job man
[dscrdeql] <tipsy_dev == (auscoi)> Cryptoon there is a plan to reward higher level holders with EQLI
[dscrdeql] <Buddz1993> It’s because of the bounty no ??
[dscrdeql] <tipsy_dev == (auscoi)> We still have that data
[dscrdeql] <Buddz1993> Ye I guess so
[dscrdeql] <Buddz1993> I was only@level 5 before this happened
[dscrdeql] <Buddz1993> And now I’m back to level 1 but with more xp xD
[dscrdeql] <blademaster> Lol start chatting folks
[dscrdeql] <blademaster> Oh man back to square one
[dscrdeql] <c2k> yup, all of us starting from zero again
[dscrdeql] <Jellysmash> we've been zeroed
[dscrdeql] <Jellysmash> only to be reborn
[dscrdeql] <KQweci-Mod> Yea it feels good to be reborn or born again I should say lol
[dscrdeql] <SwimedDragon> What does it mean to reward higher level holders with EQLI? Is that the past or current levels? Or is it about people that have a lot of EQLI?
[dscrdeql] <KQweci-Mod> Thats for the current level update
[dscrdeql] <SwimedDragon> Let's hope it gets a lot of activity from new people
[dscrdeql] <SwimedDragon> Most of us obviously have enough bought on exrates
[dscrdeql] <KQweci-Mod> I agree
[dscrdeql] <SwimedDragon> I'll probably send some more over to discord for future rains if I buy more on exrates
[dscrdeql] <SwimedDragon> Will be nice to rain once new people get in
[dscrdeql] <KQweci-Mod> Yeah and thats will keep them on and also have them invite friends to join
[dscrdeql] <KQweci-Mod> Hmmm the new update is full of surprises when you level up and they will really enjoy it

Welcome to the introduction to PyGame and Python 3 video game programming!
Suggested Requirements for this series
You may wish to be familiar with the basics of the Python 3 programming language, or at least the basics of Programming in general
That said, this course begins at a slowish pace, and I do my best to explain everything at least the first time it shows up. PyGame can actually be a wonderful starting place for your journey in Python.
Don't be afraid to ask questions!
Game creation in any programming language is very rewarding, and also makes for a great teaching tool. With game development, you often have quite a bit of logic, mathematics, physics, artificial intelligence, and other things, all of which come together for game creation. Not only this, but the topic is games, so it can be very fun.
Many times people like to visualize the programs they are creating, as it can help people to learn programming logic quickly. Games are fantastic for this, as your are specifically programming everything you see.
First, you're going to need PyGame!
Installation may vary by operating system. Macs historically have had trouble with PyGame, so you may need to get an earlier version of Python and PyGame.
Nowadays, pip is probably the best method for installing PyGame, since it comes with the latest versions of Python 2 and Python 3.
Here's a quick tutorial for using pip to install packages:
Once you have that, you're ready to create your very first PyGame instance!
import pygame pygame.init()
Above, we've imported PyGame, which is obviously necessary to make use of the module!  This will initiate PyGame, and allow you to then make various commands with PyGame and our game.
gameDisplay = pygame.display.set_mode((800,600)) pygame.display.set_caption('A bit Racey')
Next, we define our game's display, which is the main "display" for our game. You may also see this referred to as a "surface," as this is basically our canvas that we will draw things to, and the function literally returns a pygame.Surface object. We are saying right now that we want the resolution of our game to be 800 px wide and 600 px tall. Take note that this is a tuple as a function argument. If you do not make this a tuple with parenthesis, then 600 and 800 will be treated as separate parameters and the function will blow up. It's a big deal.
After that, we define our display's "caption." To me, it's more like a title, and is the title of the window. We've decided to call our game "A bit Racey." (tm!)
clock = pygame.time.Clock()
Simple enough, this is a our game clock. We use this to track time within the game, and this is mostly used for FPS, or "frames per second." While somewhat trivial seeming, FPS is very important, and can be tweaked as we will see later. For the most part, the average human eye can see ~30 FPS. It's important to note, however, that this is only a very general statement, since every human eye is slightly different, and the human eye does not process things in "frames." The better way to put it is that after about 30 FPS, people generally cannot tell the difference.
Take that 60 FPS YouTube. Anyway, we can increase FPS to literally speed up the game, or slow them down to slow down the game. This isn't ideal, especially when speeding up FPS, as the entire game loop is run per frame, and might be a massive waste of processing. More on this later though!
crashed = False while not crashed: for event in pygame.event.get(): if event.type == pygame.QUIT: crashed = True print(event) pygame.display.update() clock.tick(60)
Okay, a bit more here. I don't like to separate loops and functions if I don't have to, since it can cause people to get indentation wrong. So, first, we've got a crashed = False statement, which is just a variable that we set initially. Then, we run our "game loop," which will run until we crash. Currently, the only way we're saying crashed = True is if the user exits out of the window, however.
You'll notice here that we have a for loop within this while loop. This is going to be present in most PyGame scripts, where events are constantly being logged. It is shown in the video, but not here, but you can still try it: Try adding "print event" above the if statement. You will see in your console everything you do within the PyGame window. Pretty neat!
After our if statement. you'll see that we run a pygame.display.update. It's important to note the difference between display.update and display.flip. Display.flip will update the entire surface. Basically the entire screen. Display.update can just update specific areas of the screen. That said, if you do not pass a parameter, then update will update the entire surface as well, bascially making flip() pointless for our interests. There might come times when you want to use flip for very specific tasks, however.
The last thing within this while loop is clock.tick(60). Basically, this is how many frames per second we are running. In this case, we are running 60 FPS.
pygame.quit() quit()
Once we have broken our game loop, we want to run a pygame.quit(). This will end our pygame instance. Then we can run a simple quit(), which will exit Python and the application.


1. Introduction
In CSS Level 1 [CSS1], placing more content than would fit inside an element with a specified size was generally an authoring error. Doing so caused the content to extend outside the bounds of the element, which would likely cause that content to overlap with other elements.
CSS Level 2 [CSS21] introduced the overflow property, which allows authors to have overflow be handled by scrolling, which means it is no longer an authoring error. It also allows authors to specify that overflow is handled by clipping, which makes sense when the author’s intent is that the content not be shown.
This specification introduces the long-standing de-facto overflow-x and overflow-y properties, adds a clip value, and defines overflow handling more fully.
[Something something max-lines.]
2. Types of Overflow
CSS uses the term overflow to describe the contents of a box that extend outside one of that box’s edges (i.e., its content edge, padding edge, border edge, or margin edge). The term might be interpreted as elements or features that cause this overflow, the non-rectangular region occupied by these features, or, more commonly, as the minimal rectangle that bounds that region. A box’s overflow is computed based on the layout and styling of the box itself and of all descendants whose containing block chain includes the box.
In most cases, overflow can be computed for any box from the bounds and properties of that box itself, plus the overflow of each of its children. However, this is not always the case; for example, when transform-style: preserve-3d [CSS3-TRANSFORMS] is used on some of the children, any of their descendants with transform-style: preserve-3d must also be examined.
There are two different types of overflow, which are used for different purposes by the UA:
2.1. Ink Overflow
The ink overflow of a box is the part of that box and its contents that creates a visual effect outside of the box’s border box. Ink overflow is the overflow of painting effects defined to not affect layout or otherwise extend the scrollable overflow region, such as box shadows, border images, text decoration, overhanging glyphs (with negative side bearings, or with ascenders/descenders extending outside the em box), outlines, etc.
Since some effects in CSS (for example, the blurs in text-shadow [CSS-TEXT-3] and box-shadow [CSS-BACKGROUNDS-3], which are theoretically infinite) do not define what visual extent they cover, the extent of the ink overflow is undefined.
The ink overflow region is the non-rectangular area occupied by the ink overflow of a box and its contents, and the ink overflow rectangle is the minimal rectangle whose axes are aligned to the box’s axes and that contains the ink overflow region. Note that the ink overflow rectangle is a rectangle in the box’s coordinate system, but might be non-rectangular in other coordinate systems due to transforms. [CSS3-TRANSFORMS]
2.2. Scrollable Overflow
The scrollable overflow of a box is the set of things extending outside of that box’s padding edge for which a scrolling mechanism needs to be provided.
The scrollable overflow region is the non-rectangular region occupied by the scrollable overflow, and the scrollable overflow rectangle is the minimal rectangle whose axes are aligned to the box’s axes and that contains the scrollable overflow region.
The scrollable overflow region is the union of:
-
the box’s own content and padding areas
There’s disagreement on the scrolling model. 2.1 apparently defined that you scrolled the *content* area; the content would overflow the content-box, and you would union that overflow with the content box to find the scrollable area. In particular, this means that the content would be offset by the start-sides padding, but if it overflowed, it would go right to the edge on the end sides. This is what Firefox and IE do.
At least some authors (and spec authors) instead have the mental model that the padding box is what’s scrollable, so when you scroll to the end of the overflow, there’s the right/bottom padding. Chrome/WebKit do this for the block axis, at least. They’re somewhat inconsistent for the inline axis; there’s something weird about how they handle lineboxes.
It seems that the block-axis padding is probably web-compatible to honor. It’s unclear that the inline-axis padding will be. Further experimentation is needed.
- all line boxes directly contained by the box
-
the border boxes
of all boxes for which it is the containing block
and whose border boxes are positioned not wholly outside
its block-start or inline-start padding edges,
accounting for transforms by projecting each box onto
the plane of the element that establishes its 3D rendering context. [CSS3-TRANSFORMS]
Is this description of handling transforms sufficiently accurate?
-
the scrollable overflow regions of all of the above boxes
(accounting for transforms as described above),
provided they themselves have overflow: visible (i.e. do not themselves trap the overflow)
and that scrollable overflow is not already clipped
(e.g. by the clip property or the contain property).
should overflow: clip also clip the scrollable overflow or should it remain a pure paint-time operation, which would mean that scrollable overflow, while invisible, would still be scrollable.
Note: The mask-* properties [CSS-MASKING-1] do not affect the scrollable overflow region.
Need to evaluate compat of honoring or ignoring clip and clip-path.
-
Optionally,
additional padding on the end-edge sides,
corresponding to the end-side padding of the scroll container, such that the end edges of its in-flow content
coincide with the end edges of its content area
when scrolled to the end.
It’s not yet clear if including the end-side padding in the scrollable layer is Web-compatible, so this clause is under investigation. It appears that Chrome and Safari include such padding in the block axis; and the behavior in the inline axis is not clear. <https://github.com/w3c/csswg-drafts/issues/129>
The UA may additionally include the margin areas of boxes for which it is the containing block. The conditions under which such margin areas are included is undefined in this level. This needs further testing and investigation; is therefore deferred in this draft.
Note: The scrollable overflow rectangle is always a rectangle in the box’s own coordinate system, but might be non-rectangular in other coordinate systems due to transforms [CSS3-TRANSFORMS]. This means scrollbars can sometimes appear when not actually necessary.
3. Scrolling and Clipping Overflow: the overflow-x, overflow-y, and overflow properties
These properties specify whether a box’s content (including any ink overflow) is clipped to its padding edge, and if so, whether it is a scroll container that allows the user to scroll clipped parts of its scrollable overflow region into view. The visual viewport of the scroll container (through which the scrollable overflow region can be viewed) coincides with its padding box, and is called the scrollport.
| Name: | overflow-x, overflow-y |
|---|---|
| Value: | visible | | clip | scroll | auto |
| Initial: | visible |
| Applies to: | block containers [CSS21], flex containers [CSS3-FLEXBOX], and grid containers [CSS3-GRID-LAYOUT] |
| Inherited: | no |
| Percentages: | N/A |
| Media: | visual |
| Computed value: | as specified, except with visible/clip computing to auto/ (respectively) if one of overflow-x or overflow-y is neither visible nor clip |
| Canonical order: | per grammar |
| Animatable: | no |
The overflow-x property specifies the handling of overflow in the horizontal direction (i.e., overflow from the left and right sides of the box), and the overflow-y property specifies the handling of overflow in the vertical direction (i.e., overflow from the top and bottom sides of the box).
| Name: | overflow |
|---|---|
| Value: | [ visible | | clip | scroll | auto ]{1,2} |
| Initial: | see individual properties |
| Applies to: | block containers [CSS21], flex containers [CSS3-FLEXBOX], and grid containers [CSS3-GRID-LAYOUT] |
| Inherited: | no |
| Percentages: | N/A |
| Media: | visual |
| Computed value: | see individual properties |
| Canonical order: | per grammar |
| Animatable: | no |
The overflow property is a shorthand property that sets the specified values of overflow-x and overflow-y in that order. If the second value is omitted, it is copied from the first.
Values have the following meanings:
- visible
- There is no special handling of overflow, that is, the box’s content is rendered outside the box if positioned there. The box is not a scroll container.
- hidden
- This value indicates that the box’s content is clipped to its padding box and that the UA must not provide any scrolling user interface to view the content outside the clipping region, nor allow scrolling by direct intervention of the user, such as dragging on a touch screen or using the scrolling wheel on a mouse. However, the content must still be scrollable programatically, for example using the mechanisms defined in [CSSOM-VIEW], and the box is therefore still a scroll container.
- clip
-
Like hidden,
this value indicates that
the box’s content is clipped to its padding box
and that no scrolling user interface should be provided by the UA
to view the content outside the clipping region.
In addition, unlike overflow: hidden which still allows programmatic scrolling, overflow: clip forbids scrolling entirely,
through any mechanism,
and therefore the box is not a scroll container.
Unlike
, this value does not cause the element to establish a new formatting context.Note: Authors who also want the box to establish a formatting context may use display: flow-root together with overflow: clip.
- scroll
- This value indicates that the content is clipped to the padding box, but can be scrolled into view (and therefore the box is a scroll container). Furthermore, if the user agent uses a scrolling mechanism that is visible on the screen (such as a scroll bar or a panner), that mechanism should be displayed whether or not any of its content is clipped. This avoids any problem with scrollbars appearing and disappearing in a dynamic environment. When the target medium is print, overflowing content may be printed; it is not defined where it may be printed.
- auto
- Like scroll when the box has scrollable overflow; like hidden otherwise. Thus, if the user agent uses a scrolling mechanism that is visible on the screen (such as a scroll bar or a panner), that mechanism will only be displayed if there is overflow.
If the computed value of overflow on a block box is neither visible nor clip, it creates a new block formatting context for its content.
3.1. Overflow in Print and Other Static Media
Since scrolling is not possible in static media (such as print) authors should be careful to make content accessible in such media, for example by using @media print, (update: none) { … } to adjust layout such that all relevant content is simultaneously visible.
On scroll containers in static media with an overflow value of auto or scroll (but not ) UAs may display an indication of any scrollable overflow, such as by displaying scrollbars or an ellipsis.
Note: Not all paged media is static; for example, e-book readers page content, but are interactive.
3.2. Scrollbars and Layout
In the case of a scrollbar being placed on an edge of the element’s box, it should be inserted between the inner border edge and the outer padding edge. Any space taken up by the scrollbars should be taken out of (subtracted from the dimensions of) the containing block formed by the element with the scrollbars.
import examples from [CSS3-BOX].
3.3. Scrolling Origin, Direction, and Restriction
The initial scroll position, that is, the initial position of the box’s scrollable overflow region with respect to its border box, prior to any user or programmatic scrolling that changes it, is dependent on the box’s writing mode, and is by default the block-start/inline-start edge of the box’s padding edge. However, the align-content and justify-content properties [CSS-ALIGN-3] can be used to change this, see CSS Box Alignment 3 §5.3 Overflow and Scroll Positions.
Due to Web-compatibility constraints (caused by authors exploiting legacy bugs to surreptitiously hide content from visual readers but not search engines and/or speech output), UAs must clip the scrollable overflow region of scroll containers on the block-start and inline-start sides of the box (thereby behaving as if they had no scrollable overflow on that side).
The viewport uses the principal writing mode for these calculations.
3.4. Overflow Viewport Propagation
UAs must apply the overflow-* values
set on the root element to the viewport.
However,
when the root element is an [HTML] html
element
(including XML syntax for HTML)
whose overflow value is visible (in both axes),
and that element has a body
element as a child,
user agents must instead apply the overflow-* values
of the first such child element to the viewport.
The element from which the value is propagated must then have
a used overflow value of visible.
If visible is applied to the viewport, it must be interpreted as auto.
If clip is applied to the viewport, it must be interpreted as .
3.5. Flow relative properties: the overflow-block and overflow-inline properties
The following properties are processed according to the same processing model as the Flow-Relative box model properties defined in CSS Logical Properties 1 §3 Flow-Relative Box Model Properties.
| Name: | overflow-inline, overflow-block |
|---|---|
| Value: | <‘overflow’> |
| Initial: | auto |
| Applies to: | Same as overflow-x and overflow-y |
| Inherited: | No |
| Percentages: | N/A |
| Media: | visual |
| Computed value: | Same as overflow-x and overflow-y |
| Canonical order: | per grammar |
| Animation type: | discrete |
These properties correspond to the overflow-x and overflow-y properties. The mapping depends on the element’s writing-mode.
4. Limiting Visible Lines: the max-lines property
| Name: | max-lines |
|---|---|
| Value: | none | <integer> |
| Initial: | none |
| Applies to: | block containers (excluding multi-column containers) |
| Inherited: | no |
| Percentages: | N/A |
| Media: | visual |
| Computed value: | specified value |
| Canonical order: | per grammar |
| Animatable: | as integer |
This property allows limiting the contents of a block container to the specified number of lines; remaining content is fragmented away and neither rendered nor measured. Specifically, if the value of max-lines is not none:
- The box becomes a fragmentation container that captures region breaks, if it is not already. [CSS-BREAK-3]
-
A region break is forced after its Nth
descendant in-flow line box,
where N is the specified value of max-lines.
The contents of descendants that are scroll containers or that are not block containers are skipped over while counting line boxes.
If fewer than N line boxes exist, then max-lines introduces no region break.
-
The position of the first forced region break (whether imposed by max-lines or by another mechanism,
such as the break-before/break-after properties)
is treated as the end of the fragmentation container,
and the rest of the fragmented flow is laid out in
the next fragmentation container in the fragmentation context.
If there is no subsequent fragmentation container (which is the case if the box became a fragmentation container merely as a consequence of applying the max-lines property), the rest of the fragmented flow is discarded, similar to if it were display: none: it is neither rendered, nor measured as part of the box’s contents for the purpose of finding its min-content, max-content, or automatic block sizes, nor does allow user interaction. However, since intrinsic sizes are calculated across all fragmentation containers, this content is taken into account for the purpose of finding the box’s min-content and max-content inline sizes (see CSS Fragmentation 3 §5.1 Breaking into Varying-size Fragmentainers).
Note: In the case of parallel fragmentation flows, content occuring after the fragmentation break in the box tree could still be rendered, if it is laid out above the position representing the end of this fragmentation container.
Only positive integers are accepted. Zero or negative integers are invalid and must cause the declaration to be ignored.
Note: The widows, orphans, and break-inside properties do not affect the position of the forced region break introduced by the max-lines property.
5. Indicating Block-Axis Overflow: the block-overflow property
This section is an unofficial draft, posted here for discussion. See issue.
| Name: | block-overflow |
|---|---|
| Value: | clip | ellipsis | <string> |
| Initial: | clip |
| Applies to: | block containers |
| Inherited: | yes |
| Percentages: | N/A |
| Media: | visual |
| Computed value: | specified value |
| Canonical order: | per grammar |
| Animatable: | no |
This property allows inserting content into the last line box before a (forced or unforced) region break to indicate the continuity of truncated/interrupted content. It only affects line boxes contained directly by the block container itself, but as it inherits, will have an effect on descendants’ line boxes unless overridden. If the box contains no line box immediately preceding a region break, then this property has no effect.
Should this apply to other types of fragmentation breaks (e.g. pages, columns)?
The inserted content is called the block overflow ellipsis. Values have the following meanings:
- clip
- The rendering is unaffected.
- ellipsis
- Render an ellipsis character (U+2026)—
or a more typographically-appropriate equivalent— as the block overflow ellipsis at the end of the affected line box. UAs should use the conventions of the content language, writing system, and writing mode to determine the most appropriate ellipsis string. - <string>
- Render the specified string as the block overflow ellipsis at the end of the affected line box. The UA may truncate this string if it is absurdly long.
li { max-lines: 5; block-overflow: "… (continued on next page)"; } strong { display: block; text-transform: uppercase; }

 Cheese is Actually Made of Milk! Investigative reporters at the World Wide Web Press Corps have discovered the secret of cheese. Tracing through byzantine layers of bureacracy and shadow corporations, our crack team of journalists have traced the source of camembert.

Sample rendering:
+---------------------------------------+ | CHEESE IS ACTUALLY MADE OF MILK! | | Investigative reporters at the World | | Wide Web Press Corps have discovered | | the secret of cheese. Tracing through | | byzantine… (continued on next page) | +---------------------------------------+
When block-overflow is not clip, the block overflow ellipsis string is wrapped in an anonymous inline and placed at the end of the line box as a direct child of the block container’s root inline box, reducing the space in the line box available to the other contents of the line. This inline is assigned unicode-bidi: plaintext and is placed in the line box after the last soft wrap opportunity [CSS-TEXT-3] that would still allow the entire block overflow ellipsis to fit on the line. (This can result in the entire contents of the line box being replaced.) For this purpose, soft wrap opportunities added by overflow-wrap are ignored. Text alignment and justification occurs after placement, and measures the inserted block overflow ellipsis together with the rest of the line’s content.
If there is no next fragmentation container and thus the remainder of the content after the break would be discarded, then the UA may visually replace the contents of the line, as it does for text-overflow. If, however, there is a next fragmentation container that would receive subsequent content, then the content replaced by the block overflow ellipsis must be pushed to the next fragmentation container and the block overflow ellipsis inserted and laid out exactly as if it were part of the in-flow contents of the line. This can result in changes to layout within or impacted by the line. The means of breaking any resulting cycles is up to the UA.
If the block overflow ellipsis is too long to fit in the line, the result is undefined. (The UA may, for example, treat the block overflow ellipsis as an unbreakable string, or it may lay out the string across more than one line, replacing content in earlier lines as well.)
The block overflow ellipsis does not capture events: pointer events are dispatched to whatever is underneath or otherwise visually replaced by it.
It also has no effect on the intrinsic size of the box: its min-content and max-content sizes are calculated exactly as if block-overflow were clip.
Note: Future specifications may extend this feature, for example by providing an ::ellipsis pseudo-element to style the text, or by allowing the selection of a child element of the block to use as either an inline-level or block-level indicator (in which case, it can capture events).
6. Setting max-lines and block-overflow together: the line-clamp property
| Name: | line-clamp |
|---|---|
| Value: | none | <integer> |
| Initial: | none |
| Applies to: | see individual properties |
| Inherited: | see individual properties |
| Percentages: | N/A |
| Media: | visual |
| Computed value: | see individual properties |
| Canonical order: | per grammar |
| Animatable: | see individual properties |
The line-clamp property is a shorthand for the max-lines and block-overflow properties.
- none
- Sets max-lines to none and block-overflow to clip.
- <integer>
- Sets max-lines to the specified <integer> and block-overflow to ellipsis.
For compatibility with legacy content, UAs that support line-clamp must also support -webkit-line-clamp as an alias.
7. Privacy and Security Considerations
This specification introduces no new privacy or security concerns.

Configure Redis as Django’s Cache Engine and Session Storage Manager
原始链接：http://www.craigderington.me/configure-redis-as-djangos-cache-engine/
Redis is an open-source, persistent, in-memory data structure server that stores it’s data in key-value pairs. Redis can be used as a database, cache or message broker. Redis data structures support a variety of formats including strings, lists, sets, hashes and sorted sets. More advanced data structures include bitmaps, hyper-logs, and geo-spatial index with radius queries. Redis has built in replication, Lua scripting and transactions. It offers different levels on on-disk persistence and provides high availability and automatic partitioning.
Redis是一个开源的，持久化的，内存数据结构服务器，
Due to it’s fast, in-memory data storage retrieval, Redis is an optimal solution to be used with Django; as both a cache engine and for session storage. The primary benefit is storing cache and session data separate from your application database, which prevents unnecessary data read and write operations and can provide a nice performance boost for your Django applications.
Installing Redis
Redis is written in C and works with Unix, BSD, Linux and OS X. For our test case, we will be installing Redis on Ubuntu 14.04. OK, let’s get cooking…
Redis使用C编写，可以运行于Unix，BSD，Linux和OS X。
sudo apt-get update
sudo apt-get install redis-server
Once Redis is finished downloading and installing, check the redis-server for it’s version info to confirm it was installed correctly and is up and running.
redis-server --version
Redis server v=2.8.4 sha=00000000:0 malloc=jemalloc-3.4.1 bits=64
build=a44a05d76f06a5d9
Configure Redis
I like to connect to Redis via a Unix socket instead of TCP. This simply alleviates Redis of the overhead of managing TCP connections.
Configure Redis to communicate and accept direct socket connections, edit the /etc/redis/redis.conf file and comment out the BIND and PORT directives and uncomment the unixsocket directives.
#comment out
#port 6379
#bind <IP_ADDRESS>
#uncomment
unixsocket /var/run/redis/redis.sock
unixsocketperm 700
Save your changes and restart the Redis server.
sudo service redis-server restart
After restarting the redis-server, check to make sure the server is listening and accepting connections.
redis-cli
> ping
PONG
Success! Our Redis server is up and running.
Use Redis with Django
You will need to install the django-redis-cache module via pip in your Django project’s virtual environment in order for Django to use the Redis server for caching and session storage.
$ source .env/bin/activate
(.env)$ pip install django-redis-cache
Then add the following Redis config statement to settings.py.
CACHES = {
'default': {
'BACKEND': 'redis_cache.RedisCache',
'LOCATION': '/var/run/redis/redis.sock',
},
}
You will also need to add the following lines to your Django Middleware classes section in settings.py:
MIDDLEWARE_CLASSES = (
'django.middleware.cache.UpdateCacheMiddleware',
...
'django.middleware.cache.FetchFromCacheMiddleware',
)
Ensure the UpdateCacheMiddleware is listed first and the FetchFromCacheMiddleware is last in the Middleware classes tuple.
Now, launch your Django development server to take advantage of your new cache engine.
Using the Django cache
Django’s cache engine is extremely flexible and can be configured to cache the entire website or a single view. The behavior is controlled by using a decorator. As an example, we’ll cache the following view for 15 minutes…
from django.views.decorators.cache import cache_page
@cache_page(60 * 15)
def index(request):
...
Use Django Redis Cache Inside Functions
A nice feature of the cache engine is the ability to store data for fast and reliable retrieval…
from django.core.cache import cache
#store some data
cache.set('craig', 'derington')
#now retrieve the key's value
cache.get('craig')
#store a dict
cache.set_many({'a': 1, 'b': 2, 'c': 3})
#get the values
cache.get_many(['a', 'b', "c"])
#store more complex data structures
cache.set('my-key', {
'a string': 'this is a simple string',
'an integer': 123,
'one list': [9, 10, 11, 12, 13],
'this tuple': (1, 2, 3, 4),
'my dict': {'a': 26, 'b': 25, 'c': 24},
})
#get the values
cache.get('my-key')
Use Redis for Django Session Storage
Since we are using Redis as our caching engine, it only makes sense to use it to store our user’s session data. Again, keeping this out of the application database has many performance improvement benefits.
In the settings.py, add this line:
SESSION_ENGINE = 'django.contrib.sessions.backends.cache'
If you’d prefer to write the session information to the database and only load it from the Redis cache, use this option:
SESSION_ENGINE = 'django.contrib.sessions.backends.cached_db'
This will make sure the session data is persistent and can survive a server restart or Redis server reload.
Alternative Session Data Manager without Cache
You can also use Redis to store just the user session data without the need to use the caching engine.
Install django-redis-sessions:
(.env)$ pip install django-redis-sessions
And append the following to your Django settings.py file.
Since we are using a unix socket to connect to Redis, you must include the path.
SESSION_ENGINE = 'redis_sessions.session'
SESSION_REDIS_UNIX_DOMAIN_SOCKET_PATH = '/var/run/redis/redis.sock'
Wrapping Up
I like to visualize the data in my Redis cache. There are a number of utilities that provide a nice UI to help you visualize your Redis data. For now, I just use the command line.
$redis-cli
> info keyspace
# Keyspace
db0:keys=16, expires=0, avg_ttl=0
db1:keys=4,expires=1,avg_ttle=30411590898
To see the individual keys in the keyspace…
$ select 1
[1] keys *
1) "redis"
2) "cache"
3) "session"
4) "django1"
OK
Redis offers many benefits for Django developers. Use it as a caching engine to cache your website and as a session storage data store. The performance improvements will be quite noticeable as your site scales. You will also notice a decrease in the number of queries that are executed when using the debug_toolbar in your development environment.

REFRESH MATERIALIZED VIEW completely replaces the contents of a materialized view. The old contents are discarded. If WITH DATA is specified (or defaults) the backing query is executed to provide the new data, and the materialized view is left in a scannable state. If WITH NO DATA is specified no new data is generated and the materialized view is left in an unscannable state.
CONCURRENTLY and WITH NO DATA may not be specified together.
Refresh the materialized view without locking out concurrent selects on the materialized view. Without this option a refresh which affects a lot of rows will tend to use fewer resources and complete more quickly, but could block other connections which are trying to read from the materialized view. This option may be faster in cases where a small number of rows are affected.
This option is only allowed if there is at least one UNIQUE index on the materialized view which uses only column names and includes all rows; that is, it must not index on any expressions nor include a WHERE clause.
This option may not be used when the materialized view is not already populated.
Even with this option only one REFRESH at a time may run against any one materialized view.
The name (optionally schema-qualified) of the materialized view to refresh.
While the default index for future CLUSTER operations is retained, REFRESH MATERIALIZED VIEW does not order the generated rows based on this property. If you want the data to be ordered upon generation, you must use an ORDER BY clause in the backing query.
This command will replace the contents of the materialized view called order_summary using the query from the materialized view's definition, and leave it in a scannable state:
REFRESH MATERIALIZED VIEW order_summary;
This command will free storage associated with the materialized view annual_statistics_basis and leave it in an unscannable state:
REFRESH MATERIALIZED VIEW annual_statistics_basis WITH NO DATA;

--- layout: post title: To Name a Thing is to have Power Over It. published: true date: 2011-08-02 categories: - design - naming - programming posterous_url: http://verdammelt.posterous.com/to-name-a-thing-is-to-have-power-over-it posterous_slug: to-name-a-thing-is-to-have-power-over-it ---
(warning: an odd half-formed thought is contained herein[1])
In software development we name things to keep tabs on them. To get a handle on them. Without a name we can’t refer to things — we can’t move things around — we can’t organize them.
More importantly: to have the true name of a thing allows one to have absolute control over it. Without the true name we don’t have full power.
Naming seems to be a special case of the power of language. With language we have the power to communicate, to do things collaboratively. Names let us do actions to things, and to collaborate on those actions.
Footnotes:
[1] In a discussion on Naming in the context of Software Craftsmanship I made an odd statement linking naming in software with medieval magic and the naming of all the creatures from the Judeo-Christian Genesis myth. I thought I could expand it slightly here.
