Swift Architectural Overview¶
Proxy Server¶
The Proxy Server is responsible for tying together the rest of the Swift architecture. For each request, it will look up the location of the account, container, or object in the ring (see below) and route the request accordingly. For Erasure Code type policies, the Proxy Server is also responsible for encoding and decoding object data. See Erasure Code Support for complete information on Erasure Code support. The public API is also exposed through the Proxy Server.
A large number of failures are also handled in the Proxy Server. For example, if a server is unavailable for an object PUT, it will ask the ring for a handoff server and route there instead.
When objects are streamed to or from an object server, they are streamed directly through the proxy server to or from the user – the proxy server does not spool them.
The Ring¶
A ring represents a mapping between the names of entities stored on disk and their physical location. There are separate rings for accounts, containers, and one object ring per storage policy. When other components need to perform any operation on an object, container, or account, they need to interact with the appropriate ring to determine its location in the cluster.
The Ring maintains this mapping using zones, devices, partitions, and replicas. Each partition in the ring is replicated, by default, 3 times across the cluster, and the locations for a partition are stored in the mapping maintained by the ring. The ring is also responsible for determining which devices are used for handoff in failure scenarios.
The replicas of each partition will be isolated onto as many distinct regions, zones, servers and devices as the capacity of these failure domains allow. If there are less failure domains at a given tier than replicas of the partition assigned within a tier (e.g. a 3 replica cluster with 2 servers), or the available capacity across the failure domains within a tier are not well balanced it will not be possible to achieve both even capacity distribution (balance) as well as complete isolation of replicas across failure domains (dispersion). When this occurs the ring management tools will display a warning so that the operator can evaluate the cluster topology.
Data is evenly distributed across the capacity available in the cluster as described by the devices weight. Weights can be used to balance the distribution of partitions on drives across the cluster. This can be useful, for example, when different sized drives are used in a cluster. Device weights can also be used when adding or removing capacity or failure domains to control how many partitions are reassigned during a rebalance to be moved as soon as replication bandwidth allows.
Note
Prior to Swift 2.1.0 it was not possible to restrict partition movement by device weight when adding new failure domains, and would allow extremely unbalanced rings. The greedy dispersion algorithm is now subject to the constraints of the physical capacity in the system, but can be adjusted with-in reason via the overload option. Artificially unbalancing the partition assignment without respect to capacity can introduce unexpected full devices when a given failure domain does not physically support its share of the used capacity in the tier.
When partitions need to be moved around (for example if a device is added to the cluster), the ring ensures that a minimum number of partitions are moved at a time, and only one replica of a partition is moved at a time.
The ring is used by the Proxy server and several background processes (like replication). See The Rings for complete information on the ring.
Storage Policies¶
Storage Policies provide a way for object storage providers to differentiate service levels, features and behaviors of a Swift deployment. Each Storage Policy configured in Swift is exposed to the client via an abstract name. Each device in the system is assigned to one or more Storage Policies. This is accomplished through the use of multiple object rings, where each Storage Policy has an independent object ring, which may include a subset of hardware implementing a particular differentiation.
For example, one might have the default policy with 3x replication, and create a second policy which, when applied to new containers only uses 2x replication. Another might add SSDs to a set of storage nodes and create a performance tier storage policy for certain containers to have their objects stored there. Yet another might be the use of Erasure Coding to define a cold-storage tier.
This mapping is then exposed on a per-container basis, where each container can be assigned a specific storage policy when it is created, which remains in effect for the lifetime of the container. Applications require minimal awareness of storage policies to use them; once a container has been created with a specific policy, all objects stored in it will be done so in accordance with that policy.
The Storage Policies feature is implemented throughout the entire code base so it is an important concept in understanding Swift architecture.
See Storage Policies for complete information on storage policies.
Object Server¶
The Object Server is a very simple blob storage server that can store, retrieve and delete objects stored on local devices. Objects are stored as binary files on the filesystem with metadata stored in the file’s extended attributes (xattrs). This requires that the underlying filesystem choice for object servers support xattrs on files. Some filesystems, like ext3, have xattrs turned off by default.
Each object is stored using a path derived from the object name’s hash and the operation’s timestamp. Last write always wins, and ensures that the latest object version will be served. A deletion is also treated as a version of the file (a 0 byte file ending with ”.ts”, which stands for tombstone). This ensures that deleted files are replicated correctly and older versions don’t magically reappear due to failure scenarios.
Container Server¶
The Container Server’s primary job is to handle listings of objects. It doesn’t know where those object’s are, just what objects are in a specific container. The listings are stored as sqlite database files, and replicated across the cluster similar to how objects are. Statistics are also tracked that include the total number of objects, and total storage usage for that container.
Account Server¶
The Account Server is very similar to the Container Server, excepting that it is responsible for listings of containers rather than objects.
Replication¶
Replication is designed to keep the system in a consistent state in the face of temporary error conditions like network outages or drive failures.
The replication processes compare local data with each remote copy to ensure they all contain the latest version. Object replication uses a hash list to quickly compare subsections of each partition, and container and account replication use a combination of hashes and shared high water marks.
Replication updates are push based. For object replication, updating is just a matter of rsyncing files to the peer. Account and container replication push missing records over HTTP or rsync whole database files.
The replicator also ensures that data is removed from the system. When an item (object, container, or account) is deleted, a tombstone is set as the latest version of the item. The replicator will see the tombstone and ensure that the item is removed from the entire system.
See Replication for complete information on replication.
Reconstruction¶
The reconstructor is used by Erasure Code policies and is analogous to the replicator for Replication type policies. See Erasure Code Support for complete information on both Erasure Code support as well as the reconstructor.
Updaters¶
There are times when container or account data can not be immediately updated. This usually occurs during failure scenarios or periods of high load. If an update fails, the update is queued locally on the filesystem, and the updater will process the failed updates. This is where an eventual consistency window will most likely come in to play. For example, suppose a container server is under load and a new object is put in to the system. The object will be immediately available for reads as soon as the proxy server responds to the client with success. However, the container server did not update the object listing, and so the update would be queued for a later update. Container listings, therefore, may not immediately contain the object.
In practice, the consistency window is only as large as the frequency at which the updater runs and may not even be noticed as the proxy server will route listing requests to the first container server which responds. The server under load may not be the one that serves subsequent listing requests – one of the other two replicas may handle the listing.
Auditors¶
Auditors crawl the local server checking the integrity of the objects, containers, and accounts. If corruption is found (in the case of bit rot, for example), the file is quarantined, and replication will replace the bad file from another replica. If other errors are found they are logged (for example, an object’s listing can’t be found on any container server it should be).

Former McDonald's chief Easterbrook steps down from Walmart board
Steve Easterbrook, the chief executive officer of McDonald's Corp who was dismissed over the weekend, has resigned from Walmart Inc's board, the retailer said on Tuesday.
REUTERS: Steve Easterbrook, the chief executive officer of McDonald's Corp who was dismissed over the weekend, has resigned from Walmart Inc's board, the retailer said on Tuesday.
On Sunday, McDonald's, the world's biggest fast-food chain, said it had dismissed Easterbrook over a recent consensual relationship with an employee, which the board determined violated company policy.
"Easterbrook's decision to resign was not due to any disagreement with the company on any matter relating to its operations, policies or practices," Walmart said in a regulatory filing https://www.sec.gov/ix?doc=/Archives/edgar/data/104169/000010416919000077/form8-kx1142019.htm.
Easterbrook joined Walmart's board in 2018 and was a part of the compensation and management development, strategic planning and finance committees.

If you already know about linked lists and want to go into the specific sections then click one of the sections below.
1. Singly Linked Lists
2. Circular Linked Lists
3. Doubly Linked Lists
4. Big O of Linked Lists
Definition: Linked Lists is a data structure where every node contains a value and a pointer to the next node. A node consists of a value and a pointer which points to another value or null.
So now how do we code a linked list?
As you can see below we have the Node class which has the fields: data which is the value and next which is the pointer. So now what can we do with this class?
As of now we have made a front variable of type Node and it has been initialized to null. Now what if we set front to new Node(2,null)?
The left side shows how we code it and right side shows what does it look like right now if we draw it.
So what if we want to add another element to our linked list. Lets just say that we wanted to add 10.
We can create another block and connect it
towards the end of the original linked list as shown in the image below.
But how can we do it in Java?
We create a node object and make front point to that object. We can code it in two ways.
As you can see we have used the .next function. So what is it?
It goes to the next node. We can use multiple .next functions to go even further of the linked list.
What if we reach to null?
Since null does not have a pointer (it is the dead end of the linked list), it will throw a null pointer exception.
WE REALLY DO NOT WANT TO RUN INTO A NULL POINTER EXCEPTION!
We can traverse through linked lists using for loops and while loops.
We want to do it in a way that 1 can come before 2 and 1 becomes the new front as shown in the image below, but how?
We can make a temporary node and set its next to the original node which is a. In this case, we can return new node which is the temporary node as its next is the original linked list. The illustration and its implementation in Java can be shown below.
Suppose we want to delete the first node of a linked list. Perhaps we can just return the neighbor of the first node as shown in the code and image below.
Now lets attempt the problems below. Use the following class below for the problems. Please take a look at the four general test cases located below. These are the general test cases you should test with when you are done solving a linked list problem.
For this problem, you have to delete all of the occurences of a target in a linked list.
Answer with explanation is at the bottom.
For the last problem of this section, you have to merge two sorted linked lists using recursion.
Answer with explanation is at the bottom.
For this problem, you have to switch the pairs around of a linked list. Assume the length of the liked list will not be even.
Answer with explanation is at the bottom.
Circular linked list is a type of linked list where the nodes never reach to null meaning the last element points to the first element. Here is an example of a circular linked list below:
Since this is a ciruclar linked list, we can declare next to the node itself. This makes it a circular linked list.
So how we can insert a node at the front of the circular linked list? Assuming the front can be the end of the linked list, we can set the new node after the front.
Now lets look at the method that returns true if a value exists in a circular linked list or false if it does not. We can traverse it in a few ways. One way could be doing in a for loop while the other way can be doing it in a do-while loop.
Here is how we can code this method.
Lets look at two problems. For the problems we will deal with, we will use the class below.
For this problem, we can delete the target value of a doubly linked list and move it to the front.
Answer with explanation is at the bottom.
For this problem, we have to add a value in the circular linked list after target value is located.
Answer with explanation is at the bottom.
Unlike singly linked lists which we talked about at the beginning of this page, doubly linked lists does not just have a pointer that points
to the next node but also the node points to the previous node. Here is how doubly linked lists are built in the fields.
Here is how we can insert a node in the front of a doubly linked list.
Also we can make doubly circular linked lists. This method inserts to the front of a doubly circular linked lists.
Lets look at two problems. Use the given class below.
For this problem, we have to reverse a doubly linked list.
Answer with explanation is at the bottom.
For this problem, we have to turn a binary search tree (hyperlink it) to a circular doubly linked list
Answer with explanation is at the bottom.
Now lets explore the Big O of Linked Lists. Traversing usually takes O(n) time as we go through n nodes as shown in the image below.
Here is a chart of the worst case Big O of linked lists. Also, I have compared the time complexity with arrays.
If you do not understand array, you can take a look here.
Here is the space complexity of linked lists.

Nicki and Martins wedding went really well - much better than I'd expected, given the variety of factors which seemed to be conspiring against a happy weekend for all concerned. There's little point in going on about here in detail, as everyone who needs to know went, but: pub, thai, castle, waxwork, cake, bubbles, chocolate fountain, beer, disco-leg, wolf mask, elvis, oz, snow queen, and photography are all good places to start. The bride wore white for possibly the only time in recorded history. I didn't know there were white DMs...
Photos live here - yes, Flickr have finally persuaded me to pay for an account, the lovely lovely gits. Any other photos will be gratefully received and added here.


About Roboto
Roboto has a dual nature. It has a mechanical skeleton and the forms are largely geometric. At the same time, the font features friendly and open curves. While some grotesks distort their letterforms to forcea rigid rhythm, Roboto doesn’t compromise, allowing letters to be settled into their natural width. This makes for a more natural reading rhythm more commonly found in humanist and serif types. This is the regular family, which can be used alongside the Roboto Condensed family and the Roboto Slab family.

Abstract:
Enhanced submarine ice-shelf melting strongly controls ice loss in the
Amundsen Sea embayment (ASE) of West Antarctica, but its magnitude is not
well known in the critical grounding zones of the ASE’s major glaciers.
Here we directly quantify bottom ice losses along tens of kilometres with
airborne radar sounding of the Dotson and Crosson ice shelves, which
buttress the rapidly changing Smith, Pope and Kohler glaciers. Melting in
the grounding zones is found to be much higher than steady-state levels,
removing 300–490 m of solid ice between 2002 and 2009 beneath the
retreating Smith Glacier. The vigorous, unbalanced melting supports the
hypothesis that a significant increase in ocean heat influx into ASE
sub-ice-shelf cavities took place in the mid-2000s. The synchronous but
diverse evolutions of these glaciers illustrate how combinations of
oceanography and topography modulate rapid submarine melting to hasten
mass loss and glacier retreat from West Antarctica.


6 Thanksgiving foods you should keep away from your pets
(WVLT) -- Thanksgiving is only a week away. You may be excited about all the home-cooked dishes, but your pets may not get to enjoy as much as you.
It's important for pet owners to remember many popular dishes are not healthy for pets to eat. Gray-affiliate KALB reported your pets should stay away from the following foods:
Turkey Bones
Your pets can enjoy plain turkey, but the bones can cause severe digestion issues, including vomiting and obstructing the bowel. Bones can also splinter and cause damage to the inside of pets' stomachs and intestines.
Ham
Ham, along with other pork products, can cause pancreatitis, upset stomach, vomiting and diarrhea. The meat is also high in fat which can lead to obesity in pets.
Mashed Potatoes
Potatoes are safe for pets who are lactose intolerant but mashed potatoes can be harmful because they usually contain butter and milk. Many recipes also call for garlic or onion powder which are toxic to pets.
Stuffing
Stuffing is often made with onions and garlic which are extremely toxic for pets and can cause life-threatening anemia.
Salads with Grapes/Raisins
There are many salads served at Thanksgiving that include grapes or raisins as an ingredient, from fruit salad to Waldorf salad, to ambrosia. However, grapes and raisins are very virulent and potentially deadly. Grapes can cause severe, irreversible and sometimes fatal kidney failure in dogs. Be sure to keep all dishes that include grapes and raisins away from pets.
Chocolate Desserts
Chocolate is toxic to dogs and cats. The darker the chocolate the more toxic. Watch out because dogs love the smell and taste of chocolate despite its toxicity.
If your pet wants to join in on the Thanksgiving festivities, pumpkin pie is the safest choice. Pumpkin provides many health benefits for pets.


string implode ( string $glue , array $pieces )
Join array elements with a glue string. Note: implode() can, for historical reasons, accept its parameters in either order. For consistency with explode(), however, it may be less confusing to use the documented order of arguments.
Returns a string containing a string representation of all the array elements in the same order, with the glue string between each element.

Our mission at GUN is to make more than just great Open Source products, but to also inspire a movement of self-sufficiency. We believe your database should not be a black box of magic. We have been burnt one too many times by blindly trusting authorities. Instead, we at GUN want to do something different, we want to teach you how your data works in simple terms. That way you can call the shots.
All physical theories ought to lend themselves to so simple a description 'that even a child could understand them.' - EinsteinSo let's start with the basics, all data can be divided into three categories:
We'll explain what each one of these means, but this article is going to talk about relative ordering.
This starts with you, what if you want to build a chat app? Or a news feed for your social network? A wall of tweets streaming out from a user? Or search results for your shopping app? All these use cases share a common data structure that we say has "relative ordering". But what does that mean? We'll use an interactive explainer to show how it works. Even if you are not planning on making an app like this, we highly recommend reviewing the concept because other ideas will build off of it.
One of the players runs out to the lineup, this starts the process. It does not matter where they go because there is nothing to compare against. This also means that we have the correct ordering of height. Nothing else needs to be done. Now try to figure out where the next player belongs!
Nice job! Notice how the possible options of where a player can go has grown. For a small data set this is not a problem, it is easy to guess where they should go. But this would become difficult if we were trying to organize thousands of pieces of data. For example, what if we wanted to sort the entire audience? To make things easier, we should create a rule (or an algorithm) that lets the players find their correct position.
Try doing this yourself. Then use it to choose the correct place for the next player.
Did you make sure to test your rule against every possible option? There are interesting edge cases at the "book ends". Usually we compare the player in question to other players on both sides. But sometimes we have to compare them to nothing on one side and a single player on the other. This happens at the edges of our lineup. As humans, we intuitively understand what is correct and gloss over these details. But a computer has to be told exactly what to do. Keep on going with the interactive explainer, or check out the bonus content below.
Bonus: If we are comparing heights of the players, what do we compare against on the edges? Our first guess might be to nothing, or a 0 height. But this has two problems. First, what is on the right should always be larger than what is on the left. But if the right edge is 0 then every player will be taller than that! To a computer this could be confusing. Instead, we need to instruct the computer that if it cannot find another player to the right, then this is where the current player belongs.
Second, what if the data we're dealing with isn't height? What if the data has both positive and negative values? Instead, we need to use negative infinity, because it will always be the smaller than any other number. A lot of people are not familiar with how to use infinity though, or that it has practical value. But that is for another discussion. Often times we might deal with data that is not a number, but this is not a problem because a computer can always convert it to a number.
The important thing to note here is that the players had to make room for the new player. Because we do not know the total number of players in advance, we are unable to give them reserved spots. As a result, we have to create spots for them on the fly by shifting the other players around. This is important when building apps for two reasons.
First, your app does not have to rely on the data having been sent correctly. Anybody who has sent mail has probably experienced problems with lost mail or wrong addresses. Computers can mess up too, and building your apps this way protects you against failures because it knows how to reorder the data correctly.
Second, if you want your app to have realtime updates then it needs to know how to display the new data regardless of what it already has. In these situations, the data is never "done" because at any moment new data might stream in. This is exactly what is going on in our interactive sports explainer.
Great job! You have finished the explainer and should have a basic understanding of how relative ordered data works. While it is fairly simple, it can be used in a wide variety of applications. For instance, in a chat app a message is like one of the players in the explainer. In the same way a player has a height, a team, and points scored, a chat message has a timestamp, an author, and its contents. We can then continuously receive chat messages and display them in the correct relative order without having to load the entire history.
And there you have it! This category of data covers anything from news feeds, chat apps, to search results, or many other use cases. It is one of the most widespread types of data out there and why you should be able to understand and identify it. Having this conceptual knowledge in your mental tool belt will help you be able to pitch ideas to others, answer technical questions, communicate algorithms to your team, and even give you a basis to implement it yourself if you know how to code.
If you are interested in trying to code a chat app yourself, check out this interactive coding tutorial to get you started.
But what if the app you want to build does not fit within this category? What if you need to do more complicated stuff? Like collaborative document editing? A MMORPG game world? Graphics editor or a diagramming tool? A BOM inventory tracker? Or blockchain technology? Well, we have you covered - you are probably needing data with dependent causality. Check out the next article in this series.

KISS played a show for great white sharks in Australia – but no sharks turned up
They don't love it loud
KISS headed to Australia to play a show for an audience of great white sharks earlier this week – unfortunately, none turned up.
The rock titans announced last month that they would be heading Down Under for the special concert. It was held as part of a promotion for Airbnb’s new Animal Experiences, a travel programme catered to animal lovers.
Gene Simmons, Eric Singer and Tommy Thayer rocked up to the coast of Port Lincoln in South Australia on Monday (November 18) to perform on a boat to eight lucky fans and members of the media.
The performance was also broadcast via underwater speakers in the hope of attracting great whites, who are apparently partial to “low-frequency sounds of rock and roll”.

According to local news site ABC Eyre Peninsula, however, no sharks made an appearance during the show.
“The guys were tight, they were right into it, it was loud, there were lights, there were smoke machines,” the event’s host Matt Waller told the outlet. “It was everything that a KISS concert should be.”
KISS singer and guitarist Paul Stanley, who was ultimately forced to miss the event as he recovered from flu, previously said he was initially “a little taken aback” by the unique concept.
“I’m not sure how much of us the sharks can take,” he joked. “I’m hoping they know ‘Rock And Roll All Nite.’”
KISS, meanwhile, are set to return to UK shores next summer for a headline appearance at Download Festival. This will be followed by further ‘End of the World’ dates across Europe.

A tool for expanding variables embedded in a std::string to literals.
The input variables are provided as a map, which is allowed to change dynamically. The input std::string, issued with parse(), contains the variables as "$key" or "${key}", a format familiar in Unix shell.
- Examples
- StringMapper-example.cpp.
◆ StringMapper()
| StringMapper |
( |
const std::string & |
format = "" , |
|
|
const std::string & |
validChars = "[a-zA-Z0-9_]+" |
|
) |
| |
|
inline |
◆ expand()
| void expand |
( |
const std::map< std::string, T > & |
m, |
|
|
bool |
clear = false |
|
) |
| |
|
inline |
Expands the variables in StringMapper, turning expanded variables to constants.
- m - map containing variable values
- clear - if true, replace undefined variables with empty std::strings.
- Examples
- StringMapper-example.cpp.
◆ parse()
| StringMapper & parse |
( |
const std::string & |
s, |
|
|
bool |
convertEscaped = false |
|
) |
| |
Converts a std::string containing variables like in "Hello, ${NAME}!" to a list of StringLet's.
The Stringlet list is internal.
- Parameters
-
| s | - string containing variables like in "Hello, ${NAME}!" |
| convertEscaped | - convert backslash+letter segments to actual chars (\t,
} first |
- Examples
- StringMapper-example.cpp.
◆ toStr()
| std::string toStr |
( |
const std::map< std::string, T > & |
m, |
|
|
int |
replaceChar = -1 |
|
) |
| const |
|
inline |
Expands the variables in the last parsed std::string to a std::string.
- m - map containing variable values
- clear - if true, expand undefined variables as empty std::strings, else leave variable entry
◆ toStream() [1/2]
| std::ostream& toStream |
( |
std::ostream & |
ostr | ) |
const |
|
inline |
Output a concatenated chain of stringlets: literals as such and variables surrounded with "${" and "}".
Prints the mapper in its current state, ie. some variables may have been expanded to literals.
- Parameters

More Women!
I feel that one of the biggest issues with the tech world is the lack of women. I know that this is by no means on purpose, but this industry is seriously lacking in the female department. I have been in this industry for about 7 years now and everywhere I have worked there have been few to no girls I have encountered doing what I do. Just in NYC, men outnumber women in tech jobs 7 to 3. Even in our DBC NYC class I think there are maybe 4 women. That is a 5:1 ratio!!
Although there is still somewhat of a glass ceiling in place for women in technoloy, the tech community has been making significant efforst to increase the number of women in the industry. Groups such as Girls Who Code and Change the Ratio are taking an active role in changing this. Even coding bootcamps are actively working on getting more women by offering scholarships. The fact that there are programs available only to women to learn about tech-related fields is amazing. The industry needs to keep on encouraging and educating women young and old about this field. It is truly an amazing industry to get involved with. Talk about job security! There will ALWAYS be tech jobs. I have never had a problem finding a job (knock on wood).
This is always going to be a work in progress but I think this industry is headed in the right direction. It is growing exponentially and I feel the number of women in it will see a steady increase with it! It does not take a genius computer gamer to make a great web developer. I am only good at Dr. Mario. Let's break down that glass ceiling!

Eraserhead (1977) * * * 1/2 A movie review by Serdar Yegulalp Copyright 1999 by Serdar Yegulalp
"A Dream of dark and troubling things." -- David Lynch
There are those who say "Eraserhead" makes little sense, and then there are those who say that "Eraserhead" isn't supposed to make sense. I'm with the second camp: if "Eraserhead" made any sense at all, it wouldn't be nearly as interesting. "Eraserhead" is allegedly a horror movie, but I put it instead on that small shelf of films that abandon all pretense at being entertainment and just give you an experience: "Begotten", "The Reflecting Skin" and Alejandro Jodorowsky's head-trips ("El Topo", "The Magic Mountain") are close cousins in spirit to this film.
There is a story, sort of. Henry Spencer (Lynch regular John Nance) is a nerdish, creepy-looking man living in a squalid little apartment. He's accidentally impregnated his girlfriend, and the baby turns out to be a vile little creature that looks something like E.T. after thalidomide. The news about the pregnancy, by the way, comes out during a dinner where the main course consists of chickens the size of one's fist that still move and spurt blood when sliced into. There's also a strangely deformed woman who seems to live in Henry's radiator... and by this point you're either shaking your head in dismay or wondering where to find the movie. I guess that means I've done my job.
"Eraserhead" needs to be seen on the big screen to work properly. On TV, the black-on-black photography -- this is the single darkest movie ever made, and I don't just mean in terms of subject matter! -- reproduces very poorly. Also, on TV, the black and white images don't saturate the senses the way they do in a theater. There's also the most creative use of sound in almost any movie I've ever seen: not a single scene in the film is silent. There's always something rumbling, hissing, clattering, bubbling, booming away in either the background or the next room over, and it has the same effect on the audience's nerves as a dentist's drill.
Before David Lynch started screwing with America's mind via "Blue Velvet" and "Twin Peaks", he spent five years, on and off, making "Eraserhead". It shows. There is a level of obsessive care in every frame of this film that many movies costing hundreds of times more don't show at all.
People may wonder: If this thing's so weird and so repulsive, why did I give it three and a half stars? Because it dares to be different and succeeds. I don't automatically reward every movie that's "experimental" with a positive review, but they sure deserve the benefit of the doubt.

About Archery
Archery is the sport or skill of shooting arrows with a bow. Traditionally, this art was mainly used in hunting and combat; modern day archery consists of mainly recreational sport, competition and occasional hunting. Founded on 4 September 1931 in Poland, World Archery was set up as an international body to promote and regulate archery worldwide. All rules and archery values have been since set by them as a global standard. To date, there are three bow types which are commonly used by archers worldwide:
Recurve Bows
May be sighted or unsighted. It can be considered the most popular bow choice amongst thousands of people nowadays for competition and recreational purposes.
Compound Bows
Though a little more complex than a regular recurve bow, the compound bow is the right choice for archers who strive for power and percision. Aside from competition and recreational purposes, this bow is also widely used for hunting.
Traditional Bows
Simple (no additional gadgets or add-ons needed) and sleek in its design, the traditional bow is a good bow type to pick up if you are looking to have some casual fun. Moroever, there are also competitions held for this speicific bow type in some parts of the world.
NOTICE: Due to COVID-19, Please Remember to Stay Indoors at All Times and Be More Aware of Your Hygiene. Shoot Indoors or in Your Backyard if You Like!
Health Benefits
Whether it is done at leisure or for competition purposes, archery does bring various health benefits to those who wish to take up the sport:
Focus
An experienced archer is one who is always focused on the target and not easily distracted. Good focus is beneficial to one in a high-pressure situation.
Strength
Drawing the string, holding tension and holding the bow itself build good core and non-core strength. Constant training will strengthen the body tissues for this.
Hand-eye Coordination
Archery requires you to be able to aim with your hand as it receives feedback from the eyes. This form of coordination is built up from consistent training.
Socialise
Going for events/compeititons helps to build your social circle as you will meet a ton of archers of varied skill levels from all over the world.
Improves Confidence
Self-improvement is of utmost importance in this skilled-heavy sport. Your self-esteem will gain a boost when you notice improvement in your technique and aim.

First news from this exotic drug must have reached me around well I don't know. Back in the day. On tv this subject came up: in dutch train stations in the bigger cities Somali people were selling the drug of their choice 'Khat'. My curiousity was aroused. Not long after this I found myself talking to this Somali guy at the trainstation. He was chewing branches. Language was a bit of a problem. But he was very relaxed and gave me directions to a house where Khat was sold. When I came there they seemed quit suprised seeing me 'a native' interested in Khat. It must have been quite hilarious. Me coming in the room, crowded with khat chewing/talking man, Somali music on the background, all lookin at me with this look. And then friendliness. They sold me a bundle of khat which were stems about 2.5mm thick 15cm long, they began reddish getting lightgreen to the top with some leaves on it. They were packed in a banana leaf with some kind of organic fiber rapped around it.
A few people started explaining how to use it. First of all the stems need to be fresh(very important). Pick a stem begin at the top.  The leaves and softer part of the stem can be swollowed. The harder reddish parts are just chewed and disregarded from the mouth in a civilised way. You keep doing this until you flush it with a sip of tea or cola which they used because of the caffein content but never coffee! I personally preferred tea and if I would use khat today green tea would be my choice. The taste is unexplainable most people will find it discusting but real freax (you now who I mean) just find it tasty.
You're chewing talking and preferably in a group. And slowly while your laughing about this strange custom over the course of a couple of hours your perception has changed. The weed no longer makes us stoned. Another sip of tea and YES. It isn't a psychedelic it is euphoric/empathogenic.  Another toke of a joint and pass it to one of my friends. Who reaches to it and begins to tell a story. I listen and sink into the couch. On a other occassion me and friend were taken to a squatted house by a female friend of mine I suggested to bring some Khat. It was not the most friendly surrounding to be in.   But we didn't care we were having a good time anyway. Self esteem seemed raised along with the energy levels. The added surroundings blended very well: as they had space and electrical guitars, making it a playground.
After a while my body gets vibrant. I get somewhat sensitive to light and colors brighten. Compared with other known substances I would place it between ephedra extracts and MDMA. My friend who was their with me has a history of psychosis. And in the end of the experience when were home he felt his psychic state turn unstable. He was getting sad probably because of the action of the drug. It didn't result in anything harmful but I knew he would never do it again. Most people I know didn't like it or preferred pills or powders. My own personal experience was one of the perfect drug simply good time stuff nothing deep. Good for interacting, doing homework, cleaning up. With others or on solo journeys of self exploration. In my opinion Khat doesn't resemble cocaine and certainly not amfetamines. It's a class of its own. Sleeping afterwards was easy but it seemed like I was floathing above the bed. My mind would center in the frontal region and created spinning rollercoaster effects.
Its addicting but not uncontrollable (they sold it three times a week). There are very few after effect but they got worse the more I did it, like residue stimulation/shakiness and low enery levels.
Further I learned the active ingredient in Khat is cathinone and metabolites. It contains vitamin C (a good stimulant detoxifier) along with various minerals like magnesium. It kills parasites in the intestines. But its all a bit contradictional because one source says this the other that. Our national prince 'husband of the queen' stated in an interview he chewed Khat while working in Somalia. On the question if he liked it he just smiled and nodded so you know who is one of the real freax.

See the MediaEval 2022 webpage for information on how to register and participate.
Task participants create systems that derive insights from multimodal data to understand urban life and air pollution.
The organizers provide two datasets. The first one, namely “environmental data,” contains air quality data such as PM10, PM2.5, CO, NO2, SO2, O3 and weather factors such as temperature, humidity, wind, rainfall, and UV collected from 10 stations spread over Dalat City, Vietnam. The second one, namely “traffic data,” contains videos/images captured from the CCTV system of Dalat city, Vietnam.
The task requires participants to tackle two subtasks:
Participants are encouraged to consult the reference list below.
Improving the quality of human life in smart cities is an important objective linked directly to several United Nations Sustainable Developmental Goals, such as climate action and life on land. Urban transportation and air pollution are two key factors affecting the quality of life. To our knowledge, no literature exists that aims to understand the correlation between traffic factors (e.g., time, vehicles, trees, people), weather (e.g., rain, snow, flood), and air pollution in traffic imagery data (e.g., CCTV, lifelog camera, personal camera). This task aims to encourage participants to develop a novel and generic framework that can discover correlation (or association) between various traffic factors, weather, and air pollution in a locality. By utilizing these correlations, we aim to enhance the accuracy of AQI prediction and the ability to understand the mutual impact between urban life and Air pollution.
This task targets (but is not limited to) researchers in the areas of multimedia information retrieval, machine learning, AI, data science, data mining, knowledge discover, event-based processing and analysis, multimodal multimedia content analysis, lifelog data analysis, urban computing, urban management, environmental science, and atmospheric science.
The task introduces a novel dataset that includes weather and air quality data from ten stations and traffic data from the CCTV system. The datasets are published online at a specific website.
The weather and air quality are recorded every five minutes, including sensor’s profiles (SensorID, SensorCode, SensorName, Latitude, Longtitude, Altitude), recorded time (Date,Time), weatther (Temperature, Humidity, WindSpeed, WindGust, Direction, Rainfall), and air quality (PM1.0, PM2.5, PM10, CO, NO2, SO2, O3, UV). The traffic data contains video streaming from CCTV system. Nevertheless, the archive traffic data contains only one frame per five seconds.
The data is now online, and the participants can access the server to crawl data. Hence, the participants can prepare the ground truth by themselves.
The evaluation of the results submitted by participants will carry on as follows:
For example, July 6 is the date participants have to predict the AQI, and July 1 is the day to submit their predicted AQI values.
For each subtask, the evaluation method is applied as follows:
Here are several research questions related to this challenge that participants can strive to answer in order to go beyond just looking at the evaluation metrics:

Cultural Imperialism, Technology, and OLPC
A couple posts have got me thinking about cultural imperialism lately: a post by Guido van Rossum about "missionaries" and OLPC not about OLPC at all, a post by Chris Hardie and a speech by Wade Davis.
Some of the questions raised: are we destroying cultures? If so, what can we do about it? Must we be hands off? I will add these questions: is it patronizing to make these choices for other people, no matter how enlightened we try to be? How much change is inevitable? Can we help make the change positive instead of resisting change?
More specifically: what is the effect of OLPC on cultures where it is introduced? Especially small cultures, cultures that have been relatively isolated, cultures that are vulnerable. The internet Quechua community is pretty slim, for example. Introducing the internet into a community will lead the children to favor Spanish more strongly, and identify with that more dominant culture over their family and community culture.
Criticisms like Guido’s are common:
I’m not surprised that the pope is pleased by the OLPC program. The mentality from which it springs is the same mentality which in past centuries created the missionary programs. The idea is that we, the west, know what’s good for the rest of the world, and that we therefore must push our ideas onto the "third world" by means of the most advanced technology available. In past centuries, that was arguably the printing press, so we sent missionaries armed with stacks of bibles. These days, we have computers, so we send modern missionaries (of our western lifestyle, including consumerism, global warming, and credit default swaps) armed with computers.
This kind of criticism is easy, because it doesn’t have any counterproposal. It’s not saying much more than "you all suck" to the people involved.
Cultural imperialism is a genuine phenomena. In an attempt to subjugate or assimilate, the dominant culture may explicitly and cynically enforce its cultural norms, through its religion, requiring all schools to operate in the dominant language, even going as far as suggesting how we arrange ourselves during sex.
But it’s not clear to me that what’s happening now is cultural imperialism. It’s more market-oriented homogenization.  Similarly I think the way culture is spread currently encourages homogeneity, without explicit attempting to destroy culture.
This is where I think a protectionist stance — the idea we should just be hands-off — is patronizing.  People make decisions, what they think is the best decision for themself and their families. These decisions lead them to leave rural areas, learn the dominant language, try to conform through education, and even just lead them to enjoy a dominant culture which is often far more entertaining than a smaller and more traditional culture.
The irony is that once they’ve done this they’ve traded their position for a place in the bottom rung of the dominant society. And it’s true that in many cases they’ve made these decisions because they’ve been forced out of their traditional life by political and legal systems they don’t understand. But to blame it all on oppression is to be blind to the many concrete benefits of our modern world. Corrugated metal roofs are simply superior to thatched roofs, and we can get all romantic about traditional building processes and material independence, but we do so from homes with roofs that don’t leak. Leaking roofs are just objectively unpleasant.
So I believe that assimilation pressure is natural and inevitable in our times.
What then of technology, of the internet and laptops?
I believe OLPC takes an important stance when it selects open source and open licensing for its content. It is valuing freedom, but more importantly encouraging self-determination, trying to build up a user base that can act as peers in this project, not as simply receivers of first-world largess. But it will be culturally disruptive. And I’m okay with that. In a patriarchal culture, giving girls access to this technology will be destructive to that power structure. Yay! I believe in the moral rightness of that one girl making her own choices, finding her own truths, more than I believe in the validity of the culture she was born into. If you believe people should be able to make their own choices (so long as they are aware of the real consequence of their choices), then you must allow for them to choose to abandon their own cultures for something they find more appealing. They might know better than you if that’s a good choice. I think we all hope that instead they transform their own cultures, but that’s not our choice to make.
What I find unpleasant is if they leave a true identity to find themselves in a place of cultural subservience. If they feel they can’t preserve the part of their culture they most value. Perhaps because of discrimination they feel they must hide their past, or they build up a sense of self-loathing. Perhaps they become isolated, unable to find peers that understand where they come from. And perhaps there is no higher culture at all that they can use to exalt their understanding of the world — do they have a literature? Do they have non-traditional music forms of their own? Do they have a forum where people who share their perspective can have serious discussions? Cultures aren’t destroyed so much as they are starved out of existence.
I think assimilation is inevitable, and can be positive. If we were all able to speak to each other, with some shared second or third language, I think the world would be a better place. I’m not a Christian, but I’m not afraid of anyone knowing The Bible. There’s no piece of culture that I would want to deny from anyone. Each new song, each new book, each new idea… I believe they will all make you a better person, if only in a small way.
And on the internet our culture is cumulative. There’s only so many hours of programming on TV or the radio, only so many pages in a newspaper. On the internet the presence of one kind of culture does not exclude any other. There’s room for a Quechua community as much of any other. But the online Quechua community won’t have exclusive rights to its members like a traditional culture claims — children will live between cultures.
Cumulative culture is not a promise that anyone will care. Languages can still die, cultures can still die, identities become forgotten. If these smaller cultures are going to be preserved, they must adapt to the partially-assimilated status of their members. There must be new art and new ideas and new identities. This is why I believe in the laptop project, because it can enable the creation and sharing of these new ideas. I think it will give smaller cultures a chance to survive — there’s no promises, literature doesn’t write itself, but maybe there is at least a chance.
This is also why I am more skeptical of mobile phones, audio devices, and any device that doesn’t actively enable content creation. Mobile phones are not how culture is made. It let’s people chat, consume information, communicate in a 12-key pidgin. But the mobile phone user is not a peer in a world wide web of information. The mobile phone user lives on a proprietary network, with a proprietary device, and while it perhaps it breaks down some hierarchies through disintermediation, it does so in a transient way. The uptake is certainly faster, but the potential seems so much lower.
I don’t know if OLPC will be successful. That’s as unclear now as ever. But it’s trying to do the right thing, and I think it’s a better chance than most for maintaining or improving the richness of the worlds’ culture.

Hey Everyone,
This month's meetup will be on September the 4th, talks will start at 7:30pm and it's at the usual place, you know it, you love it, yes, the Brewery Tap.
So far we have one volunteer, Mr Dan Higham with his talk; "Ruby and the Cloud (Foundry)". He's just got a new job at VMWare so hopefully we'll find out all manner of trade secrets!
I need one more speaker if possible? Any volunteers?
See you all then!
Tom


I made a library.
It's fast.
It's well documented.
It's easy to use.
It uses abstract interpretation to efficiently infer inductive invariants like this:
\( S = R \uplus \{x\} \uplus T \quad \wedge \quad Q = P \setminus T \)
var point = { x: 1, y: 2 };
point.x; // read x field
point.y; // read y field
point.z = 3; // add z field
point[“w”] = 4; // add w field
“z” in point; // ask if z exists
for(i in point) {} // iterate over fields
// i = [“w”, “y”, “x”, “z”]

tl;dr; ask next week
Mylo(KomodoPioneers)Today at 1:11 AM
@Buddz1993 no set date. we have some optimizations to do so 3rd parties can verify properly.
Buddz1993Today at 1:12 AM
AWS are confirmed tho right?
you will be utlizing their services?
Mylo(KomodoPioneers)Today at 1:13 AM
yes. for our stuff. we have the funding already from AWS marketing to use for this test.
we'll start with 64 chains optimized, then ramp them up each test leading up to it, 64 > 128 > 512 > 1024 and more if we can and have budget left.
Buddz1993Today at 1:14 AM
