Any type of server you run at your site may introduce the potential for inappropriate access to your site, and a Web server is no exception. This chapter will attempt to acquaint you with some of the most common security issues that confront the Webmaster or Web team and how to design policies and implement procedures to deal with them.
The first thing to consider when choosing server software to run at your site is its origin. Some Web servers are freely available in source form. Having the source code that comprises the server available for inspection may lend to your assurance that it is trustworthy or reliable. At the very least, you're able to inspect the source code and possibly make modifications to it, to make it conform to your own policies. On the other hand, access to the source code also gives the unsavory few the means to study the code for the purpose of cracking your system. Other servers are proprietary, and their source code is not freely available. Precompiled servers that run on platforms other than UNIX are the most common, but there are also precompiled proprietary servers available for various UNIX platforms. Since neither the admin nor anyone else can study their code, they introduce the notion known as "Security by Obscurity," both for their inner workings and for their delivery and encryption mechanisms. The origin of security by obscurity is to be found within the world of cryptography, and it actually refers to certain cryptographic algorithms that rely on the secrecy of certain components to be reliable and safe. Cryptographic techniques used in Web service will be discussed later in this chapter. Within the realm of programs you might decide to run on your computer, however, the notion of security by obscurity is not necessarily a good thing for a number of reasons.
- Placing your trust in the proprietary inner workings and encryption techniques that are components of these servers may also lead to unforeseen security holes.
- Many UNIX sysadmins just will not run any program on their machines unless they've compiled its code themselves or, in the hardcore case, unless the program came on the OS distribution tape/CD as an official supported component of the OS.
- Some servers provide more comprehensive (thus restrictive) mechanisms for enabling security, and others provide only the standard means for implementing a security policy. It's often the case that the freely available servers provide the most comprehensive mechanisms for controlling and/or restricting access. On the other hand, adding complexity to a server's internal mechanisms may also increase the likelihood for security oversights in its design.
Whichever type of server you choose to run and architecture you choose to run it under, you'll need to be conscientious and methodical in all of your activities relating to the management of the server and its archive. Just because a server is purported to be safe and reliable doesn't mean that a trained monkey can manage it. The Webmaster should also make an effort to stay up-to-date and well informed regarding the latest information on security problems related to the server, the archive, and the OS the server runs under. The day-to-day activities and procedures that comprise a sound security policy are highly dynamic in nature, due to the constant struggle between those who would crack your system and those who discover these holes and dispense the information necessary to close them up.
Note:
One important thing you can do to prevent unwanted access and/or retrievals of your archive's contents is to plan your archive's layout well. Chapter 14, "Archive and Document Management," discusses this further. Good archive planning and an established policy for the various aspects of server management and archive updating lend to your ability to configure the server's security mechanisms on a discrete but not overly restrictive basis. After all, too much rigor may tend to chase away well-intentioned but perhaps slightly inexperienced browsers and/or customers.
General Server Security
The security mechanisms the server itself provides vary from server to server and from architecture to architecture. Whatever server you choose to run, you should understand security and spend the time to implement them. Especially if you're running under a multi-user architecture like UNIX, you can easily overlook an item that may cause a potential hole.
Note:
It's the general consensus that of all the platforms on which you can run a WWW server, the one that is least likely to cause you security problems is the Macintosh. The fact that the Macintosh doesn't provide the capability to log in from anywhere but the console reduces the risks involved with providing external access to its filesystem. This also makes it a bit more difficult to manage the archive's contents as a team, of course, but this issue can be worked around through the Macintosh's file-sharing mechanisms. You may wish to investigate this alternative to a UNIX server.

It all started about 6:00 P.M. on saturday me, my brother and a few of his friends all took about the same amount. We then decided to walk around a bit. After about 20 minutes we all began to feel a buzz comming on so we started home. After another 10 minutes we really started tripping my one friend was standing in some old lady's yard and watching her t.v. She came out and called the police.
We tried to get him to leave with us, but he wouldn't move. The cops got there and called him over to the car. He raised his hands and yelled, I think he was trying to scare them away. Both of them tackled him and proceeded to 'subdue' him resulting in him having many cuts and scars on his face.
 Both of us were on our way home, tripping our nuts off when my brother dissappeared, it turns out he wasn't around me for a long time.
The next thing I can remember is being arrested and brought to the hospital.  Then gave me an I.V. they transfered me to a different hospital because I was under 18. On the way there I remember I kept trying to sit up and play with my knife, which I didn't have. When we arrived at about 4:30 AM they stuck me in a room and I got out of my bed and rode my I.V. pole down the hallway. When the nurse caught me I said the dog made me do it, althought I don't know why. I talked to my I.V.pole for awhile and blacked out. They found my brother laying in the road talking to the sidewalk. And one of the other people they found in an alley with one shoe and a pissed pants.
Don't do this drug.

I’m currently making my second trip through Jared Richardson’s excellent book Career 2.0: Take Control of Your Life. In the “Public Speaking” chapter, one of the recommended avenues for public speaking practice is Toastmasters. I first heard of Toastmasters…you guessed it, on my first trip through the book. Shortly after returning home from NFJS St. Louis, I decided to see if I could find a local club. Lo and behold, a Toastmasters club already meets on the St. Jude Children’s Research Hospital campus! I had no excuse but to check it out at this point.
For the uninitiated, Toastmasters is an organization focused on helping individuals hone their communication and leadership skills in a safe environment. This is accomplished primarily through three different avenues:
Serving in one of the meeting leadership roles, such as Toastmaster (the meeting facilitator);
Giving a prepared speech/talk from the list of speech projects in the Toastmasters “coursework”;
Speaking extemporaneously on one of several “table topics,” which are speaking prompts provided during the meeting.
Participation in any of these avenues is immediately followed up with feedback from one or more people playing various “evaluator” roles. I couldn’t help but see the parallels to agile software development!
I’ve now attended three meetings, and at the last meeting I decided to join up. The St. Jude club is an extremely friendly group, and several of its members are very accomplished public speakers. You can definitely tell that the Toastmasters experience has helped them enhance their communications skills. I’m looking forward to polishing my own.

| ago | horns | fleece |
| king | Greece | loved |
| playing | Helle | grass |
| garden | catch | clouds |
Long, long ago there lived a king in Greece. He had two little children, a boy and a girl.
They were good children and loved each other very much.
One day they were playing in the garden.
"Oh, Helle, look!" said the boy.
There on the grass was a fine large sheep. This sheep had a fleece of gold and his horns were gold, too.
The children wanted to pat the sheep, but they could not catch him. When they went near, he ran away on the clouds.
| grew | golden | hold |
| tame | ride | tight |
Every day they played in the garden and every day the sheep came, too.
By and by he grew tame and let the children pat his golden fleece.
One day the boy said, "Helle, let us take a ride."
First he helped his sister on the sheep's back.
Then he got on and held to the horns.
"Hold tight to me, Helle," he said.
| sky | dizzy | sea |
| sister | land | dragon |
| lose | nailed | Colchis |
The sheep went up, up into the sky, and ran a long way on the clouds. But Helle got dizzy and fell down into the sea.
The boy felt very bad to lose his sister, but went right on.
Then he came to the land Colchis. He killed the sheep and gave the golden fleece to the king.
The king was glad to have it and nailed it to an oak tree.
By the tree was a dragon. The dragon never went to sleep. He would not let any one but the king come to the tree.
So no one could get the golden fleece.
| across | untied | wade |
| Jason | brave | party |
| rained | creek | bridge |
| shoe-strings | invited |
Jason was a brave young man. He lived a little way from the king's city.
One day the king gave a big party and invited Jason.
It was a very dark night and it rained hard.
Jason had to go across a creek, but there was no bridge.
The creek was full of water and Jason had to wade.
One of his shoe-strings came untied and he lost his shoe in the water.
When he came to the king's housexx, he had but one shoe.
| knew | bring | fight |
| wild | Argo | asked |
| animals | shoe | Argonauts |
The king did not like this, for a fairy had said, "The man who shall come to your housexx with one shoe, will be king."
So he knew Jason was to be king. Then he said to Jason, "You may be king when you bring me the golden fleece."
Jason was glad to go, and asked many brave men to go with him.
To get the golden fleece they would have to fight wild men and animals.
They made a big ship which they named "Argo."
The men who went on the Argo were called Argonauts.
| wings | blind | nobody |
| strong | iron | hard |
| skin | drive | claws |
| scratched | brass | Harpies |
The ship Argo sailed a long way. There were two strong men on the ship. They had wings and could fly.
One day the Argo came to a land where the blind king lived.
This poor king had a hard time. When he sat down to the table to eat, some ugly birds called Harpies, came too. The Harpies had skin like brass and nobody could hurt them. They had claws of iron, and scratched people when they tried to drive them away.
When the king's dinner was ready, the Harpies came and took it away. When Jason and his men came, the king told them all about it. Jason said they would help him.
| food | drowned | tired |
| swords | hurt | flying |
They all sat down to the table. When the food was put on the table, the Harpies came flying in. Jason and his men took their swords.
They cut at the Harpies but could not hurt them.
Then the two men with wings flew up in the air. The Harpies were afraid and flew away. The men flew after them.
At last the Harpies grew very tired and fell into the sea and were drowned.
Then the men with wings came back.
Now the blind king could eat all he wanted.
| thanked | rocks | moved |
| friends | helping | good-bye |
| over | apart | icebergs |
It was now time for Jason and his friends to go away.
The king thanked them over and over again for helping him.
When they said good-bye, he told them how to get to the land where they would find the golden fleece.
On the sea where Jason and his men had to sail, were two big rocks. These rocks moved on the waterlike icebergs.
They were as high as a big hill. They would come closeyy to each other, then they would go far apart.
| fishes | pieces | doveyy |
| past | break | together |
| rowxx | almost | rocks |
When fishes swam in the water the rocks would come together and kill the fishes.
If birds flew in the air, the rocks would come together and kill birds.
If a boat sailed on the water, the rocks would come together and break the boat into little pieces.
These rocks had been put in the sea, so no one could go to the land where the golden fleece was.
When the ship Argo came to the rocks, Jason sent a doveyy out.
The rocks came together when the doveyy was almost past.
Then they went far apart. Jason made his men rowxx as hard as they could.
The rocks began to come together. "Rowxx hard, my men," said Jason.
Just as they got past, the rocks hit, but Jason and his men were all right.
So they came to Colchis.
| something | plow | bulls |
| stronger | chains | noses |
| mouths | smoke | plant |
| stone | flew | stall |
When Jason came to Colchis, he went to the king and said, "Will you give me the golden fleece?"
The king wanted to keep the fleece.
So he said to Jason, "You may have it, but you must do something for me first."
"You must plow with the brass bulls, and plant the dragon's teeth."
The brass bulls looked like real bulls, but they were larger and stronger.

The bulls had a stall made of iron and stone. They had to be tied with strong iron chains.
| daughter | Medea | carriage |
| snakes | through | pulled |
When the dragon's teeth were planted, iron men grew up.
They always killed the one who had planted them.
The king wanted the bulls to kill Jason.
He said, "If the bulls do not kill him the iron men will."
The king had a daughter named Medea. She saw Jason was a brave young man and did not want him killed.
She knew how to help him. She stepped into her carriage, which was pulled by flying snakes.
Then Medea flew through the air. She went to hills and creeks and picked all kinds of flowers.
She took the flowers home and cooked them.
| nothing | face | rub |
| juice | legs | cut |
Then Medea went to Jason when the king did not know it.
She said to Jason, "Rub your face and hands and legs with this juice."
When he did this, he was as strong as a giant.
Nothing could hurt him then. Fire could not burn him, and swords could not cut him.
The next day Jason had to plow with the brass bulls and plant the dragon's teeth.
| climbed | early | tied |
| princess | seats | hold |
| untied | opened | place |
Early in the morning, the king and princess went out to the place.
They had good seats where they could see well.
All the people in the city came out to see Jason plow.
The little boys climbed the trees so they could see better.
Then Jason came to the place. The stall where the brass bulls were tied was not far off.
The door was opened and Jason went in.
He untied the bulls and took hold of their horns.
Then he made the bulls come out of their stall.
| pushed | kicked | until |
The bulls were very angry and blew fire and smoke from their mouths.
This made the cruel king glad. But the people who saw it were afraid. They did not want Jason killed. They did not know that the princess had helped him.
Jason pushed the bulls' heads down to the ground. Then they kicked at him with their feet, but could not hurt him.
He held their heads down on the ground until the plow was ready.
| handle | slowly | noon |
| wheat | lie | just |
Jason took the chains in one hand. He took the handle of the plow in the other.
The bulls jumped and wanted to run away.
But Jason held so hard they had to go very slowly.
When it was noon the ground was all plowed.
Then Jason let the bulls go.
They were so angry that they ran away to the woods.
Now Jason went to the king and said, "Give me the dragon's teeth."
The king gave him his hat full.
Then Jason planted the dragon's teeth, just as a man plants wheat.
By this time he was very tired, so he went to lie down.
| evening | knees | marble |
| threw | growing | fight |
In the evening he came back.
The iron men were growing up. Some of the men had only their feet in the ground.
Some of them were in the ground up to their knees.
Some had only their heads out.
Then Jason did what Medea told him he should do.
He took a giant's marble and threw it near the men.
All the iron men wanted to get the marble.
So they began to fight each other. As soon as one had his feet out of the ground, he cut at the man next to him. So they killed each other.
Then Jason took his sword and cut off all the heads that were out of the ground.
So all the iron men were killed and the king was very angry.
But Medea and the people were glad.
| yourself | fond | father |
The next day Jason went to the king and said, "Now, give me the golden fleece."
The king did not give it to him, but said, "Come again."
Then Medea said, "If you want the golden fleece, you must help yourself. My father will not give it to you. A dragon is by the tree where the golden fleece is, and he never sleeps. He is always hungry and eats people if they go near him. I can not kill him but I can make him sleep. He is very fond of cake. I will make some cake and put in something to make the dragon sleep."
| became | climbed | angry |
So Medea made the cakes and Jason took them and threw them to the dragon.
The dragon ate them all and went to sleep.
Then Jason climbed over the dragon and took the nail out of the tree.
He put the golden fleece under his coat and ran to the ship Argo.
Medea went with him and became his wife.
Oh, how angry the king was! He had lost the golden fleece and the brass bulls and the dragon's teeth. And now his daughter was gone.
| through | nine | stones |
He sent his men in ships to take Jason, but they could not get him.
At last Medea and Jason and the other Argonauts came to Greece.
Jason's father was there. He was a very old man. Jason wanted his father to be king, so he asked Medea to make the old man young.
Then Medea took her carriage and flew through the air.
She did not come back for nine days. She picked flowers from the hills. She found all kinds of stones, too.
| stick | died | woke |
When she went home she put all these things into a pot and cooked them.
Then she put a stick into the pot and leaves grew on it.
Some of the juice fell on the ground and grass grew up.
So Medea knew the juice would make things grow.
Jason's father went to sleep and Medea put some of the juice into his mouth.

When he woke up, he looked and felt like a young man.
He lived many years and when he died Jason was king.

Anki Vector .NET SDK
The Vector SDK gives you direct access to Anki Vector's unprecedented set of advanced sensors, AI capabilities, and robotics technologies including computer vision, intelligent mapping and navigation, and a groundbreaking collection of expressive animations.
About this SDK
This SDK gives full access to all of Vector's hardware and software features available from the most recent (and final) version of Vector's firmware. This even includes some features currently not available from of the official Python SDK including face enrollment and adjusting Vector's permanent settings. The API design follows the design of the Python SDK but deviates in a few places for simplicity or consistency with the gRPC API.
Getting Started
Prerequisites
- Vector is powered on.
- You have successfully created an Anki account.
- Vector has been set up with the Vector companion app.
- The Vector companion app is not currently connected to Vector.
- Vector is connected to the same network as your computer.
- You can see Vector’s eyes on his screen.
Download Microsoft development tools
If you working on Windows, download Visual Studio 2019 Community Edition to get started. This version is free for personal use.
To get started on Mac and Linux, you can download .NET Core 3.0.
Install SDK package from nuget
Make sure your Vector robot is connected to the same Wifi as your computer using the Vector companion app.
Vector SDK Configuration and Authentication
In order to use the SDK, you need authenticate with the robot and create a configuration file that is stored in your user profile. This SDK uses the same configuration file as the Python SDK and the Vector Explorer application.
The easiest way to get setup with Vector on your Windows PC is to install Vector Explorer and configure your robot through that application. However, you can also use the command line VectorConfigure application on Windows, Linux, and Mac OS.
You will be prompted for your robot’s name, ip address and serial number. You will also be asked for your Anki login and password. Make sure to use the same account that was used to set up your Vector. These credentials give full access to your robot, including camera stream, audio stream and data. Do not share these credentials.
Vector Explorer: https://www.weekendrobot.com/vectorexplorer
VectorConfigure: https://www.weekendrobot.com/devtools
SDK Example / Tutorial Programs
You can download the samples Visual Studio solution containing tutorial projects and management applications.
Troubleshooting
Tutorial program does not run
Before running a the program, be sure you can see Vector’s eyes. If instead you see an image of a mobile device, the Customer Care Info screen, a missing Wifi icon, or something else, please complete setup of your Vector first and then you will be ready set up the SDK.
Vector behaves unexpectedly
You may need to reboot your robot when you are finished running programs with the Vector SDK.  To turn him back on again, place him back on the charger.
Can't find robot name
Your Vector robot name looks like "Vector-E5S6". Find your robot name by placing Vector on the charger and double-clicking Vector’s backpack button.
Can't find serial number
Your Vector’s serial number looks like "00e20142". Find your robot serial number on the underside of Vector. Or, find the serial number from Vector’s debug screen: double-click his backpack, move his arms up and down, then look for “ESN” on his screen.
Can’t find Vector’s IP address
Your Vector IP address looks like "<IP_ADDRESS>". Find the IP address from Vector’s debug screen: double-click his backpack, move his arms up and down, then look for "IP" on his screen. Note that the SDK will attempt to find Vector's IP address automatically.
Advanced Tips
Asynchronous API
All API calls that talk to Vector in this SDK are asynchronous methods. This means that methods in the SDK will return before the operation is completed. Each method returns a Task instance that updates when the operation completes or fails. The intended way to calls these methods is to declare your methods as async
and use the await
keyword for each call. This gives the illusion of using synchronous calls while supporting asynchronous operation.
For more information on asynchronous programming with async
and await
, click here.
Also you can look at all the code samples (see below) for more examples on using async
/await
with this SDK. Any methods that return a Task
instance should be called with the await
keyword. Any methods that use await
should be declared async
and return a Task
. Event handlers and the main
method of a project can be declared async
and start most operations.
Moving Vector between Wifi networks
The SDK will automatically discover your Vector, even on a new WiFi network, using mDNS. If this doesn't work, you may have to specify the IP address explictly when connecting to Vector with the SDK.
Using multiple Vectors
If your computer is configured with more than one Vector robot, you can specify which robot you want to use by passing its serial number or robot name as a parameter to the Robot.NewConnection
method.
using (var robot = await Robot.NewConnection("00e20142"))
{
await robot.Control.RequestControl();
await robot.Behavior.SayText("Hello World");
}
or
using (var robot = await Robot.NewConnection("Vector-B2R5"))
{
await robot.Control.RequestControl();
await robot.Behavior.SayText("Hello World");
}
Keeping Vector Still Between SDK Scripts
Vector can be controlled so that he will not move between SDK scripts. There is an example command-line application in the Anki.Vector.Samples project and a Windows Tray application available at https://www.weekendrobot.com/devtools.
While normal robot behaviors are suppressed, Vector may look 'broken'. Closing the SDK scripts, disconnecting from the robot, or restarting the robot will all release behavior control.

Lady Gaga shares bridesmaids photos from her best friend's wedding
Singer’s makeup artist tied the knot over the weekend
by Sarah YoungLady Gaga has shared photographs of her as a bridesmaid at her best friend’s wedding this weekend.
On Sunday, the A Star is Born actor posted several images to her Instagram Story from the wedding of her long-time makeup artist Sarah Tanno.
In one of the photographs, Gaga could be seen posing in a floor-length satin pink gown, which matched her current bubblegum pink hair.
Holding up a bouquet of flowers in celebration, Gaga wrote: “Two of my best friends just got married. Time to party!”
The “Applause” singer also tagged Tanno, with whom she created her new beauty line Haus Laboratories, and the makeup artist’s now-husband Tim Stewart.
In another image, Gaga posed with one of the other bridesmaids on the beach as they each put one leg up while holding their flowers.
The 33-year-old also shared a photograph of the bride and groom, writing “Congratulations I love you” alongside a pink heart emoji.
The night before the wedding, Tanno shared a photograph of the entire bridal party, including Gaga, to her Instagram.
The singer was captured wearing a cut-out black dress and large hoop earrings with her pink hair styled in a simple bun.
Last month, Gaga attended Tanno’s bachelorette party despite being “in a lot of pain,” as it came just one day after the singer fell off stage during a performance and landed on her back.
“I might be in a lot of pain but I couldn’t miss my best friend’s bachelorette dinner,” Gaga wrote alongside a selfie from the night out.
In the image, Gaga posed with a pair of pink “bridesmaid” glasses, which perfectly coordinated with her new hair colour.
In October, the actor unveiled her vibrant tresses as she celebrated the A Star Is Born soundtrack selling six million copies worldwide.
“A year ago, A Star was Born, and here we are six times pink platinum,” she wrote alongside a photograph of her holding the accolade.
This isn’t the first time that the “Bad Romance” singer has switched up her platinum blonde locks.
In January, the singer even coordinated her hair with the periwinkle ballgown she wore to the Golden Globes.


No routes found that satisfy the route specification. Try setting an arrival deadline futher into the future (a few weeks at least).

WE'RE GONNA DO WHAT THEY SAY CAN'T BE DONE
10-4 Good City a place to focus on some of the more popular ideas of What If Greenville. We'd like to discuss the idea and find out if people are interested in turning this idea to action.
Our first topic is a walkable Main Street. At least a half dozen people submitted this idea and below is a Greenville News editorial by Marc Bolick of DMarc8 on why he thinks this is a good idea.
We’ve all heard the story. Greenville’s downtown used to be an anti-destination. It is where you didn’t go at night or on the weekends. That has changed now, and we are all proud to show visitors how wonderful our Main Street area is. But if you had asked the average person 20 years ago whether Main Street could be a thriving hub of restaurants, shops and street festivals, most would have said "no way!"
By all accounts, the vision of Greenville’s leaders over three decades ago has proven accurate: if you build an attractive streetscape and provide the right incentives, you can create a vibrant and thriving downtown. I think that a key aspect of the revitalization of downtown was the so-called “road diet” that was imposed on Main Street, reducing it from four lanes to two. This was done intentionally to make the area more pedestrian friendly. So, my question now is, why not go all the way and make a large portion of Main Street pedestrian-only?
Think about it. When you head downtown and you turn onto Main Street anywhere between College and Broad, you just know that you’re going to end up driving slow and have very little chance of finding parking on Main itself. Just the other day around lunchtime I stood in front of the Westin Poinsett and looked north up Main Street. All I could see were cars waiting at traffic lights. I stood there imagining what it would be like to have no cars, no parking, just a wide pedestrian area with more outdoor restaurant seating, a bike lane and maybe an electric bus or trolley running down the center of Main.
Many people will object to this idea, and the arguments against are important to consider. Retailers on Main Street would lose the vital drive-by traffic that attracts walk-in customers. Parking capacity would be reduced (around 100 spaces). And, perhaps most compellingly, the argument is made that pedestrianisation has been tried in other US cities and “it didn’t work.” These are all good points, and any new street design should take these and other considerations into account.
But, let’s remember the arguments against tearing down the “perfectly good” Camperdown bridge that is now the Liberty (walking!) Bridge. That $13 million public investment in the Falls Park project stimulated well over $100 million in private investment that has transformed downtown Greenville. Our Main Street has become a case study for cities across the country and internationally for how to revitalize a city. We should continue to lead and make Greenville’s Main Street a pedestrianised area, for the health of the city’s economy and for the health of our citizens.

PDF is a recent evolution of PostScript. Whereas PostScript was intended to be consumed by printers, PDF is designed for both online viewing and printing. It allows for features such as clickable links, clickable tables of contents, and sounds. It is intended as a final form for documents. You could possibly edit PDF if you had a few months to spare, but it isn't easy. It also remedies some basic problems with PostScript. (PostScript contains arbitrary subroutines that might generate pages in a loop or subject to conditions; so the only way to look at page 499 of a 500-page document, or even to know that there are 500 pages, is to execute the code and render it all.)
For the average developer, PDF is compelling because the Acrobat Reader is freely and widely available on almost all platforms. This means you can produce a document that can be emailed, stored on the Web, downloaded, and printed at leisure by your users, on almost any platform. Furthermore, all they get is the document, not any attached spreadsheets or data they shouldn't, and you can be confident it won't be tampered with. For this reason, many companies are looking at PDF as a format for much of their documentation.
PDF documents are generally created in two ways, both of which involve buying Adobe Acrobat. This includes PDFWriter, a printer driver that lets you print any document to a PDF file; and Distiller, which turns PostScript files into PDF files. These are excellent tools that fulfill many business needs.
PDF is a published specification, and in the last two years, a C library and a Perl library have been written to generate PDF directly. This was too much of a challenge to resist, so we have done one in Python, too.
Technically, PDF is a complex language. The specification is 400 pages long. If you don't want to know the details, skip to the section Section 10.7. If you do, it'd be a good idea to open one of the sample PDF files provided with this chapter; unlike most you will find on the Web, they are uncompressed and numbered in a sensible order. We've provided a brief roadmap to the PDF format as we feel that it offers many benefits, and you might want to add your own extensions in the future.
The outer layer of the PDF format provides overall document structure, specifying pages, fonts used, and advanced features such as tables of contents, special effects, and so on. Each page is a separate object and contains a stream of page-marking operators; basically, highly abbreviated PostScript commands. The snippet of PostScript you saw earlier would end up like this:
72 720 m 72 72 l /F5 24 Tf 42 TL 80 720 Td ('Hello World') Tj
Unfortunately this code, which can at least be decoded given time and you know where to look, can be compressed in a binary form and is buried inside an outer layer that's quite complex. The outer layer consists of a series of numbered objects (don't you love that word?) including pages, outlines, clickable links, font resources, and many other elements. These are delimited by the keywords obj and endobj and numbered within the file. Here's a Catalog object, which sits at the top of PDF's object model:
1 0 obj << /Type /Catalog /Pages 3 0 R /Outlines 2 0 R >>
Every object is a dictionary of keys and values. The Catalog is at position 1 in the file. It has a Pages collection, found at location 3 in the file. The Pages collection might contain individual Page objects, or perhaps other Pages collections with subranges of the document. These form a balanced tree, so that an application like Acrobat Reader can locate the drawing code for page 3,724 in a 5,000 page document in one second flat.
Once you get to a Page object, you'll find a declaration of the resources needed to draw the page, which includes a list of fonts used and might include graphics function sets to load into memory and a reference to a Contents object. A simple page and its associated small Contents object might look like this:
20 0 obj << /Type /Page /Parent 3 0 R /Resources << /Font << /F1 5 0 R % list of font declarations /F2 6 0 R % - font objects are described elsewhere /F3 7 0 R % in the file /F4 8 0 R /F5 9 0 R >> /ProcSet 3 0 R % reference to the sets of Postscript >> % drawing procedures to be loaded for page /MediaBox [0 0 612 792] % page in points - 8.5x11 US paper /Contents 21 0 R % reference to next object >> endobj 21 0 obj % beginning of contents object << /Length 413 >> % predeclare the stream length stream % line 2 units wide from 72,72 to 72, 720 q 2 w 72 72 m 72 720 l S Q BT % begin text mode /F6 48 Tf 80 672 Td 48 TL % set font, position and size (48 pt) (PDFgen) Tj T* % display a line of text /F5 24 Tf24 TL % smaller font 80 640 Td % set text origin (Automatic PDF Generation) Tj T* % more text ET % end text mode endstream endobj
Lurking near the bottom, between the stream and endstream keywords in the Contents object, you finally get to the page-marking operators. Note also that the length of the stream of contents operators is predeclared to allow it to be read quickly.
Finally, typically at the end of the document, you find an index section that looks like this:
xref 0 24<PHONE_NUMBER> 65535 f<PHONE_NUMBER> 00000 n<PHONE_NUMBER> 00000 n<PHONE_NUMBER> 00000 n <lines deleted to save space><PHONE_NUMBER> 00000 n trailer << /Size 24 /Root 1 0 R /Info 19 0 R>> startxref 7164 %%EOF
When Acrobat Reader opens a file, it looks in the last few bytes for the keyword trailer. The trailer object on the following line tells us that there are 24 objects in the file; that the root is object number 1; and that information such as the document author and date are available at object number 19. It then tells us that the cross-reference table is found starting at byte 7164 in the file. The cross-reference table itself (beginning at xref in the first line) shows the positions of the objects; thus object 1, the root, is at byte 17 in the file, and object 24 is at byte 5167.
This mechanism makes it possible to parse and process PDF documents quickly, but it made developing a PDF generator harder. With HTML or PostScript, you get instant gratification each time you output a well-formed chunk of code, and you can start in a small way; with PDF, you can't even look at it until you have correctly indexed the whole thing.
The PDFgen.py module wraps and hides most of this from the user and constructs a well-formed document. Many advanced features are missing, but the documents do open cleanly. The module does this by having Python classes that mirror the PDF ones and by building up a list of objects in memory. When it writes the file, each returns a text representation of itself for the file, and the PDFDocument class measures the length of this. The module is thus able to build a valid index at the end. What it doesn't do is the drawing. The module presumes that something else feeds it a complete contents stream for each page. This is where the PIDDLE interface comes in.
We won't go further into the implementation of the outer layer of the PDF library here. Instead we'll look at a few details of the current frontend.
Once the PIDDLE API was stable, it was fairly straightforward to implement a PDFCanvas object to provide a simple API. Let's take a quick look at some of the methods of the PDFCanvas class and how they hook up with the backend:
def __init__(self, filename): Canvas.__init__(self) self.filename = filename self.code = [] # list of strings to join later self.doc = pdfgen.PDFDocument() self.pageNumber = 1 # keep a count # various settings omitted
When it starts up, the PDFCanvas instance creates a PDFDocument instance. This is the class that manages the overall document structure. It also creates an empty list, self.code, to hold strings of page-marking operators. The various drawing methods add the right operators to the list in the same way the PostScript snippets did earlier. If you compare the methods and output with the PostScript PSCanvas, it's easy to see the correspondence.
When you ask for a new page with the showPage() method, this happens:
def showPage(self): page = pdfgen.PDFPage() stream = string.join([self.preamble] + self.code, '\n') #print stream page.setStream(stream) self.doc.addPage(page) self.pageNumber = self.pageNumber + 1 self.code = [] # ready for more...
First, create a PDFgen object called PDFPage , which is responsible for generating the output later. Then make a big string of page-marking operators by joining a standard preamble (which does some work to set up coordinate systems, default fonts, and so forth) and the list of accumulated operators. This is stored in the PDFPage, which is then added to the PDFDocument. PDFgen takes care of the rest when asked to save itself to disk. Finally, the page number is incremented, and the list of strings is emptied, ready for some more output.

Global identifiers from different JavaScript environments
Extracted from JSHint and ESLint and merged.
It’s just a JSON file, so use it in whatever environment you like.
This module no longer accepts new environments. If you need it for ESLint, just create a plugin.
$ npm install --save globals
```js var globals = require(‘globals’);
console.log(globals.browser); /* { addEventListener: false, applicationCache: false, ArrayBuffer: false, atob: false, … } */ ```
Each global is given a value of true
or false
. A value of true
indicates that the variable may be overwritten. A value of false
indicates that the variable should be considered read-only. This information is used by static analysis tools to flag incorrect behavior. We assume all variables should be false
unless we hear otherwise.

Check out our used aloha shirts. Very quality shirts with modern designs. Used shirts mean lower prices. We also have stickers so you can spread the Aloha Fridays idea.
Let us show you what the Aloha lifestyle is all about. We are on Instagram, Twitter, Snapchat and soon, Youtube.
Stay connected with our weekly updated blogs. We like to keep you connected with the new ideas for living the Aloha lifestyle.
The idea branched from my father's company BERG located in Spokane, Washington. Every friday they have Aloha Friday where you wear an aloha shirt to work. Now it was time to make it into a lifestyle. Why just friday? Why not live every day like it is friday?
Started out selling used Hawaiian shirts on EBay to start the idea. Got started on social media. Instagram, twitter and Facebook.
The transition to having a good time and drinking with friends and trying to get others to adopt the lifestyle. This includes beer reviews, and inspirational quotes. Also the addition of the Aloha Fridays sticker and the creation of the logo.
Aloha Fridays is starting a Youtube channel with vlogs. Also starting to blog about the newest beer trends and favorites. The next idea is to create an Aloha Fridays playlist on spotify to listen to when you are sitting on that patio drinking your favorite beer. More to Come!

Prime Academy
Prime is a full stack software engineering bootcamp. There I learned new skills, Javascript Full Stack Development, and was then able to use those skills to build projects. Through Prime, I have created a base to begin work as a software developer. Though I have learned so much, I still have a lot of learning left to do. To me, Prime is merely the first step in a much longer journey.
College Possible
Before Prime I did an Americorps term at College Possible, a St. Paul based non-profit. For College Possible, I was working at four partner schools in the Twin Cities Metro helping high school students get into college. College Possible was a formative experience for me as I worked with students from a wide range of backgrounds, and though I have ultimately moved away from that work, I still value my experience at College Possible as some of the best in my life.
Starr Health Scheduling Web App is a full-stack web application with the purpose of helping Students connect with Starr Health Coaches who match their needs and connect with those Coaches. This is my group project from Prime Digital Academy. I was responsible for the Full Stack scheduling function of the application. It was an opportunity to for me to stretch my experience and apply logic to build complex functionality.
https://github.com/alex-aspell/StarrHealth_project Close ProjectThis is my solo project from Prime Digital Academy. Rate-iology was inspired by frustration that movie rating websites are both too complicated in their rating systems and do not provide users with enough useful and interesting information. It uses a scale of 0-100 to allow users to be more specific with their ratings. Rate-iology gives movies a heat rating which reflects how divisive or agreed upon movie ratings are. It also collects demographic data to show how people in different demographics feel about various films. I built the entire site and it reflects where my knowledge and skill was at that point.

I made it using the template from StartBootstrap and customized it to my liking. Why did I include it? Well to be perfectly honest, I haven't made a whole lot of good looking applications that I want to showcase yet. However, I will be very soon. I'll be featuring new projects and this will be replaced. So enjoy it while you can.

Tucked into the northern shore of Tor Bay, Torquay is a typical seaside resort. Holidaymakers are attracted by the wide sands and the better than average amounts of sunshine which occur in its micro-climate.
Position 50°27.4'N, 03°31.7'W.
In settled weather, there are several anchorages around the Bay, but none providing all-round shelter close to Torquay.
The harbour has a marina and a town dock, both of which provide visitors' berths. There is also a floating pontoon alongside Haldon Pier, which protects the southern side of the harbour.
The inner harbour (access over a sill), is usually full of local boats.
A nice alternative to the town is to take a mooring in Babbacombe Bay.


Recently I found myself without access to the computing clusters that I usually use for research and am currently relying on just a few desktops to get some results in the meantime. I need to run a very large number of relatively small size molecular simulations (Monte Carlo and Molecular Dynamics), which luckily is a perfect application for GNU parallel. Due to the small size of each individual simulation, there wouldn't be a lot to gain by using LAMMPS's MPI capabilities, and running each simulation on an individual thread on my desktop is even faster than running on our very old cluster. Now I just need to efficiently make full use of all the cores on the desktops I have to run the individual simulations.
For some time I was writing custom bash scripts that would run processes in the background and I would manually have to monitor their completion before starting a new simulation. Supposing I have to run N
simulations and have max_procs
that I can use on a given machine, I would do something like:
for i in $(seq 1 $N); do
A = check_num_active_processes()
while [ "$A" -ge "$max_procs" ] ; do
sleep 10
done
./run_simulation.sh $i &
done
The problem is the function check_num_active_processes()
takes some additional effort to write, and maybe sometimes you just want more functionality than the bare bones script above.
Luckily GNU Parallel removes all sorts of headaches and presents a one-liner replacement for the above script with infinitely more functionality. In my case, ./run_simulation.sh
takes only one command line argument, so the above script can executed much more robustly:
for i in $(seq 1 $N); do echo $N; done | parallel -j 8 --timeout 86400 --delay 1 "./run_simulation.sh {}"
And if you your ./run_simulation.sh
takes multiple parameters, you can pipe them by making sure to specify an empty space between arguments with the colsep keyword:
T=300; for i in $(seq 1 $N); do echo $N $T; done | parallel -j 8 --timeout 86400 --delay 1 --colsep ' ' ./run_simulation.sh {1} {2}
As simple as that, you can seemlessly run N
simulations using 8 cores (with some additional options specified). With three desktops available to me, I can get a factor of 24x speedup compared to running serialized jobs on a single thread per machine. This is a huge timesaver for me since I have to execute ./run_simulation.sh
thousands of times to get the data I need.

--- layout: archive title: Zulip Chat Archive permalink: /stream/116395-maths/topic/sheafification.html ---
@Scott Morrison @Reid Barton It seems that on a general site, sheafification needs localisation of categories and calculus of fractions. I would like to hear from you if you think it is realistic to work on this now, or is this to hard for now?
@Johan Commelin I suppose those topics should be doable, but I wonder whether you really need them.
I'm confused by the proof of Proposition 2.1 at https://ncatlab.org/nlab/show/sheafification#existence. It seems that we are done immediately after quoting "result 1", if all we care about is the existence of a sheafification functor.
I suppose you also want to produce something resembling a formula for it?
Hmmm, I hope that it wouldn't matter how we prove the existence (by a construction, or indirectly) as long as we can provide an API. We will want the universal property (i.e. adjunction), the fact that sheafification is idempotent and that it preserves stalks.
OK, so the first two properties (which are essentially the same thing) are valid for the full subcategory of presheaves which are local with respect to any set of maps, not just one which comes from a coverage.
That fact is not so easy, but it's on my to-do list--it follows from the small object argument.
I'm not sure exactly what the third statement means, but it sounds potentially formal, in the right setup.
Ok, cool! I'm not surprised that localisations are not-so-easy. But I think it would be awesome if we could have them.
For stalks: either you do this for points of a topos, and I would think it is then pretty formal (but maybe less intuitive for those not familiar with them, like me). Or you do it for stalks of points in a topological space, which is less general, and you would have to build more bridges. But large parts of it should be formal anyway, since stalks are by definition filtered colimits, and I hope those are preserved by the right sort of adjoint functor.

He said that he was delighted at the growing interest of the global community in investing in the oil and gas-rich state, assuring that investors would not regret doing business there.
According to him, people of the state are hospitable and the environment is quite conducive for investments to thrive.
“We are very hospitable people in Delta and I am happy that good relationship exists between our country and the Czech Republic.
“Your coming to Delta is worth applauding, because you are in a state with limitless potential for investors.
“We hope this visit will lead to partnership that will mutually benefit us, because as a people and as a government, we are happy and always ready to partner people who can add value to us.
“There is a lot of gap in the energy sector and any investor in that area will not get it wrong, as we are looking forward to a situation when we will get enough energy supply to stimulate desired economic growth.
“We are currently developing the Kwale Industrial Park; there are lots of areas for industrialisation and our entrepreneurship programmes and the education sector are areas that we are happy to get partnership”.
Earlier, the ambassador said he was in Asaba to see how his country could partner the people on investment.
He said that Czech Republic was known for mechanized farming, industries, education, military prowess, among others.
