Hi Christian,
To me, legal but not sensible values should be allowed -- some of the
variable and value selection strategies implemented by Gecode probably are
not very sensible also. In addition, the AFC decay factor can be set to 0
already using afc_decay(0.0), so making the initialision of an IntAFC
consistent with that seems reasonable to me.
Also, the decay factor for IntActivity can be set to 0, although I guess it
might make more sense here, as AFC is only changed when a failure occurs.
Cheers,
Kish

Patterns
A pattern represents the structure of a single value or a composite value. For example, the structure of a tuple (1, 2)
is a comma-separated list of two elements. Because patterns represent the structure of a value rather than any one particular value, you can match them with a variety of values. For instance, the pattern (x, y)
matches the tuple (1, 2)
and any other two-element tuple. In addition to matching a pattern with a value, you can extract part or all of a composite value and bind each part to a constant or variable name.
In Swift, there are two basic kinds of patterns: those that successfully match any kind of value, and those that may fail to match a specified value at runtime.
The first kind of pattern is used for destructuring values in simple variable, constant, and optional bindings. These include wildcard patterns, identifier patterns, and any value binding or tuple patterns containing them. You can specify a type annotation for these patterns to constrain them to match only values of a certain type.
The second kind of pattern is used for full pattern matching, where the values you’re trying to match against may not be there at runtime. These include enumeration case patterns, optional patterns, expression patterns, and type-casting patterns. You use these patterns in a case label of a switch
statement, a catch
clause of a do
statement, or in the case condition of an if
, while
, guard
, or for
-in
statement.
Grammar of a pattern
pattern → wildcard-patterntype-annotationopt
pattern → identifier-patterntype-annotationopt
pattern → value-binding-pattern
pattern → tuple-patterntype-annotationopt
pattern → enum-case-pattern
pattern → optional-pattern
pattern → type-casting-pattern
pattern → expression-pattern
Wildcard Pattern
A wildcard pattern matches and ignores any value and consists of an underscore (_
).  For example, the following code iterates through the closed range 1...3
, ignoring the current value of the range on each iteration of the loop:
for _ in 1...3 {
// Do something three times.
}
Identifier Pattern
An identifier pattern matches any value and binds the matched value to a variable or constant name. For example, in the following constant declaration, someValue
is an identifier pattern that matches the value 42
of type Int
:
let someValue = 42
When the match succeeds, the value 42
is bound (assigned) to the constant name someValue
.
When the pattern on the left-hand side of a variable or constant declaration is an identifier pattern, the identifier pattern is implicitly a subpattern of a value-binding pattern.
Grammar of an identifier pattern
identifier-pattern → identifier
Value-Binding Pattern
A value-binding pattern binds matched values to variable or constant names. Value-binding patterns that bind a matched value to the name of a constant begin with the let
keyword; those that bind to the name of variable begin with the var
keyword.
Identifiers patterns within a value-binding pattern bind new named variables or constants to their matching values. For example, you can decompose the elements of a tuple and bind the value of each element to a corresponding identifier pattern.
let point = (3, 2)
switch point {
// Bind x and y to the elements of point.
case let (x, y):
print("The point is at (\(x), \(y)).")
}
// Prints "The point is at (3, 2)."
In the example above, let
distributes to each identifier pattern in the tuple pattern (x, y)
. Because of this behavior, the switch
cases case let (x, y):
and case (let x, let y):
match the same values.
Tuple Pattern
A tuple pattern is a comma-separated list of zero or more patterns, enclosed in parentheses. Tuple patterns match values of corresponding tuple types.
You can constrain a tuple pattern to match certain kinds of tuple types by using type annotations. For example, the tuple pattern (x, y): (Int, Int)
in the constant declaration let (x, y): (Int, Int) = (1, 2)
matches only tuple types in which both elements are of type Int
.
When a tuple pattern is used as the pattern in a for
-in
statement or in a variable or constant declaration, it can contain only wildcard patterns, identifier patterns, optional patterns, or other tuple patterns that contain those. For example, the following code isn’t valid because the element 0
in the tuple pattern (x, 0)
is an expression pattern:
let points = [(0, 0), (1, 0), (1, 1), (2, 0), (2, 1)]
// This code isn't valid.
for (x, 0) in points {
/* ... */
}
The parentheses around a tuple pattern that contains a single element have no effect. The pattern matches values of that single element’s type. For example, the following are equivalent:
let a = 2 // a: Int = 2
let (a) = 2 // a: Int = 2
let (a): Int = 2 // a: Int = 2

Enumeration Case Pattern
An enumeration case pattern matches a case of an existing enumeration type. Enumeration case patterns appear in switch
statement case labels and in the case conditions of if
, while
, guard
, and for
-in
statements.
If the enumeration case you’re trying to match has any associated values, the corresponding enumeration case pattern must specify a tuple pattern that contains one element for each associated value. For an example that uses a switch
statement to match enumeration cases containing associated values, see Associated Values.
Grammar of an enumeration case pattern
enum-case-pattern
→
type-identifieropt.
enum-case-nametuple-patternopt
Optional Pattern
An optional pattern matches values wrapped in a some(Wrapped)
case of an Optional<Wrapped>
enumeration. Optional patterns consist of an identifier pattern followed immediately by a question mark and appear in the same places as enumeration case patterns.
Because optional patterns are syntactic sugar for Optional
enumeration case patterns, the following are equivalent:
let someOptional: Int? = 42
// Match using an enumeration case pattern.
if case .some(let x) = someOptional {
print(x)
}
// Match using an optional pattern.
if case let x? = someOptional {
print(x)
}
The optional pattern provides a convenient way to iterate over an array of optional values in a for
-in
statement, executing the body of the loop only for non-nil
elements.
let arrayOfOptionalInts: [Int?] = [nil, 2, 3, nil, 5]
// Match only non-nil values.
for case let number? in arrayOfOptionalInts {
print("Found a \(number)")
}
// Found a 2
// Found a 3
// Found a 5
Grammar of an optional pattern
optional-pattern
→
identifier-pattern?
Type-Casting Patterns
There are two type-casting patterns, the is
pattern and the as
pattern. The is
pattern appears only in switch
statement case labels. The is
and as
patterns have the following form:
is type
pattern as type
The is
pattern matches a value if the type of that value at runtime is the same as the type specified in the right-hand side of the is
pattern—or a subclass of that type. The is
pattern behaves like the is
operator in that they both perform a type cast but discard the returned type.
The as
pattern matches a value if the type of that value at runtime is the same as the type specified in the right-hand side of the as
pattern—or a subclass of that type. If the match succeeds, the type of the matched value is cast to the pattern specified in the right-hand side of the as
pattern.
For an example that uses a switch
statement to match values with is
and as
patterns, see Type Casting for Any and AnyObject.
Grammar of a type casting pattern
Expression Pattern
An expression pattern represents the value of an expression. Expression patterns appear only in switch
statement case labels.
The expression represented by the expression pattern is compared with the value of an input expression using the Swift standard library ~=
operator. The matches succeeds if the ~=
operator returns true
. By default, the ~=
operator compares two values of the same type using the ==
operator. It can also match a value with a range of values, by checking whether the value is contained within the range, as the following example shows.
let point = (1, 2)
switch point {
case (0, 0):
print("(0, 0) is at the origin.")
case (-2...2, -2...2):
print("(\(point.0), \(point.1)) is near the origin.")
default:
print("The point is at (\(point.0), \(point.1)).")
}
// Prints "(1, 2) is near the origin."
You can overload the ~=
operator to provide custom expression matching behavior. For example, you can rewrite the above example to compare the point
expression with a string representations of points.
// Overload the ~= operator to match a string with an integer.
func ~= (pattern: String, value: Int) -> Bool {
return pattern == "\(value)"
}
switch point {
case ("0", "0"):
print("(0, 0) is at the origin.")
default:
print("The point is at (\(point.0), \(point.1)).")
}
// Prints "The point is at (1, 2)."

Today I want to present my first contribution to Docker community - Jenkins Rails image.
For better understanding what work was done I propose to look into Dockerfile. At first lines you can see system upgrades, installing Rails requirements and npm. Secondly, we ignore auto generated docs and install useful plugins.
That’s it! Is it so little? Maybe, but it’s enough for start. Almost.
Are you want to know how to use and extend it for your needs? What are you waiting for - press a “Read more” button.

How to extend
In few cases you find something missing in this based image. Fortunately, it’s easy to extend.
Firstly, create your own Dockerfile.

The Zoldyck family owns and lives at Kukuroo Mountain, a dormant volcano in the Dentora region of the Republic of Padokia, which stands at 3,772 meters. Their estate is surrounded by huge stone walls guarded by a giant dog named Mike and attendants highly skilled in martial arts. Only few people unrelated to the family have any idea what is within the estate. There are a lot of mysteries surrounding the Zoldyck family; a single photo of any of the members can be sold for millions.
Killua has spiky silver hair, very pale skin and blue eyes. His eyes change shape depending on the mood that he's in, narrowing and sharpening when he goes into assassin mode. Killua is fairly lean at the start of the series, due to constant physical conditioning and torture training he received when he was young. As time passes, he becomes more muscular and toned. In the Nippon Animation anime adaptation, Killua's eye color is changed to green during the OVAs. He is also often seen holding a green skateboard (turned yellow in the 2011 series).


Link building is an acute part of SEO work, and refers to accumulating websites that that link back to our website, otherwise known as Backlinks. Quality backlinks coming from credible and high-ranking websites have a pivotal-role in ranking our website in SERPs. There are many methods, white-hat (legitimate), as well as black-hat (illegitimate) to procuring backlinks - obviously when dealing with black hat methods, such as buying links from 3rd party vendors theres a lot of risk and a small rewards if any, and these methods will many times cause more harm than good to your SEO status.
Backlinks are links arriving at our website from outside sources. Quality backlinks coming from credible and high-ranking websites have a pivotal role in ranking our website in SERPs. Similarly, backlinks arriving from low-ranking or untrustworthy websites lower our ranking upon indexing.
Check out this awesome HubSpot article listing white-hat methods for link-building
Not all backlinks are created the same, in fact there are some backlinks that can even hurt your position on SERPs, depending on where they’re coming from. This has to do with the credibility and reputation of the website who’s doing the backlinking, if it’s a low-reputation site such as a scam, porn-site, black-hat forum, the backlink provided will most likely reduce our SEO position. if it’s from a very well established website with good reputation, let’s take TechCrunch for the sake of example, then it can even elevate our SEO ranking ten-fold.
A great tool for researching website ranking’s is Moz Lin Explorer
When we see a low ranking website providing a backling to our website, it’s important for us to disavow that link in order to keep our SEO standing using Google Search Console
Interlinks are links from one page on our domain to another page on the same domain. While Interlinks won’t elevate our SEO ranking in any way, they will make our website more index-digestible and engage our user-base more effectively by advising with the content-segments and user-engagement with one article opening up to several more to keep session-engagement on our domain, as well as allow backlinkers to link to article-series instead of just one article.
Silos is a highly effective method of website organization moving from longtail keywords to larger themes with one website organizational architecture. Read More
Data from a few industry studies indicate the correlation between long content (1000+ words) and higher rankings. This is not difficult to understand, as mentioned in “Longtail Keywords” section, as the number of long-tail searches performed are increasing every day. Additionally, web users are becoming smarter every day. They want specific answers to specific questions. The long-form content pieces perform better and add immense value to your audience by going beyond just scratching the surface. Your content strategy needs to match their increasing savvy.
The first step of any email outreach campaign is to find people that already write about your content’s topic. You could go to the blog directory site ALLTop.com and search, for example, “best ‘your topic’ blogs”. Then, you could choose the sites from the results and make further efforts to have them check out your content.
To get in touch the people you just found, the two-step email outreach process.
Step 1 : To avoid annoying someone that is not interested in your content, the first email is a “feeler” email, which just simply gauges the person’s interest in your content.
Step 2 : If you receive the response, then you could start your pitch.
The two-step email outreach process converts much better while most people send their link pitch in their first email and get poor reply rate.

My first iteration of turaew.io proved successful but when I shared the site with my wife, she could not get past how horrible it looked on her mobile phone.
I intended for her to view it on her laptop but she insisted on checking it out on her phone (no doubt fueled by my request to use a laptop).
I was not going to make my site public until I had some responsiveness but my wife’s reaction underlined the importance of this task.
Learning to apply Bootstrap I also wanted to know a little bit more about how responsive design came about.
Responsive design was primarily and initially written on extensively by Ethan Marcotte in 2010. Marcotte said that responsive design has three main tenants:
A fluid grid is one that’s built using a relative unit of measurement like ems or percent instead of pixels.
Flexible image means that the images resize as part of the design, they generally display larger on a big-screen, and they scale down as the size reduces.
Media queries allow you to define different styles for different screen widths.
Prior to the creation of responsive design there was adaptive layout which was written about by Marc den Dobbelsteen.
Adaptive design uses a fixed width grid system in which a screen will resize once specific widths are reached. One major distinction seems to be that adaptive design will not always fill up an entire screen the way a fully-responsive design does.

Iowa vs. Minnesota: Game Time, Spread, Channel, Announcers
by Alek ArendThe Big Ten slate on Saturday features a marquee game with two ranked teams. No. 8 Minnesota at No. 20 Iowa will certainly garner plenty of attention this weekend.
Undefeated Minnesota wasn’t expected to be lossless at this point in the season. But here the Golden Gophers are.
P.J. Fleck’s squad shocked the college football world last Saturday, beating then-No. 4 Penn State. As a result, the Golden Gophers jumped up to No. 8 in the latest College Football Playoff rankings. Many feel that ranking is still too low.
This Minnesota team is to be taken seriously. And the Golden Gophers look to make another statement on Saturday against the Iowa Hawkeyes.
Iowa is 6-3 (3-3) through nine games this season. The Hawkeyes don’t have much of a shot at a Big Ten title. But taking down Minnesota would certainly be an impressive feat.
Here’s all the details for Saturday’s Big Ten contest:
Game Time: 4 p.m. ET
Channel: FOX
Spread: Iowa -3
Over/Under: 44.5
Announcers: Joe Davis, Brock Huard, Bruce Feldman
Minnesota may be the higher ranked team on Saturday, but the Hawkeyes are a 3-point favorite at home. This is expected to be a low scoring affair on Saturday.
Iowa-Minnesota kicks off at 3 p.m. ET on FOX. Joe Davis and Brock Huard will be calling the game.
Iowa won last year’s game in Minneapolis 48-31, and is riding a four-game winning streak in the battle for Floyd of Rosedale, one of the Big Ten’s best trophies.

When measuring gravity on Earth, we must also take into account the tidal effects of the Sun and
Moon
on the reading, as depending on each body's location relative to the surveyor, a positive or
negative
gravitational correction must be made to the reading. This effect can be on the order of several
hundred
microGals depending on the relative positions of the Sun and Moon.
The graph shown here displays the total tidal gravity correction (Sun and Moon) at DgS's office
location
in Broomfield, CO. The correction is calculated using the method proposed by Ivor M. Longman in his
1959 paper
Formulas for Computing the Tidal Accelerations Due to the Moon and the Sun.
The data displayed here is for informational/demonstration purposes only. As the tidal correction for
gravity is
location dependent, and the values displayed here are calculated only for our location.
However please feel free to visit our GitHub page and download a copy of the source code from the
link below.
Coming soon: We are developing a web-based tool which will allow you to input a location
(latitude/longitude/altitude), and generate a table of tide corrections over a specified time
period.
The calculated correction should be subtracted from the gravity data.
You can view the source code used to compute the tidal correction seen here, on GitHub:
TideGravity
If you use Python 3 in your environment, you can also download and install our Tide Gravity library
from
the Python Package Index (PyPi) via pip:
pip install tidegravity


Family's fury over M&S Christmas tree that's getting scathing reviews
Marks and Spencer advertises the £35 tree as a “sparkling surprise”
by Jack Longstaff, Max ChannonA mother has blasted Marks and Spencer after discovering her new fake Christmas tree looks like "a twig without any leaves".
Aniela Jasionowicz, 29, bought the £35 tree - which comes with a set of decorations - from the M&S website.
But she said the 6ft decoration looks nothing like the bushy tree on the website.
Aniela from Cheshunt in Hertfordshire, said: “I was hugely disappointed because we put a lot of time and effort into putting the tree up.
“We took it down straight away because it looks awful.
“It looks like a twig without any leaves. I expected a quality product but that’s not what we got.
“The image on the website does not represent the product and I feel like we were sold short.”
Marks and Spencer advertises the tree as a “sparkling surprise” and comes with pre-lit lights and 59 separate decorations.
Personal assistant Aniela, who is married to Stefan 29, said the couple were especially excited to decorate their house for their daughter’s first Christmas.
Talia is six-months-old and Aniela wanted to make this Christmas extra special for her.
But with just over two weeks to go before Christmas the family are yet to find a replacement tree and have been given a refund by M&S following a complaint.
Aniela added: “The photo of it online looked great and I thought it’d look really nice.
“I thought I had got myself a great deal.
“But for me it is false advertising. I was really disappointed because it looks like a completely different tree altogether.”
Other less than impressed customers have left some equally scathing reviews about the product online.
One shopper gave the tree a one star rating, saying it is of "poor quality" and "not value for money".
Other people said: "The tree is very cheaply made and looks dead."

ICN "Begin-End" Hop by Hop Fragmentation
draft-mosko-icnrg-beginendfragment-XX
This document describes a simple hop-by-hop fragmentation scheme for ICN and mappings to the CCNx 1.0 and NDN packet formats, called "begin-end fragmentation". This scheme may be used at Layer 3 when ICN packets are used natively over a Layer 2 media which does not reorder packets.

In the past, there were two known hop-by-hop fragmentation schemes for ICN packets: The one described in NDNLP [NDNLP] as "indexed fragmentation" and the one implemented in CCN-lite [CCNLite], using the old ccnb encoding. In a first part, this document describes a third, hop-by-hop fragmentation protocol in an encoding-neutral way. In a second part, we show mappings of this "begin-end fragmentation scheme" to the CCNx Messages in TLV Format [CCNMessages] and the NDN TLV [NDN] encoding. Thirdly, possible extensions and their encodings are discussed, for example reporting link reliability or link ARQ schemes such as windowing protocols.
The proposed hop-by-hop "begin-end fragments" scheme may be used at Layer 3 when large ICN messages are to be natively sent over a Layer 2 media with a small MTU. In cases where ICN packets are carried over an existing Layer 3 protocol, such as IP, the Information Centric Network SHOULD use that protocol's native fragmentation.
This proposed fragmentation scheme is an adaptation of PPP Multilink PPP Multilink [RFC1990] fragmentation between peers identified by their Layer 2 identity. It is appropriate for standard Layer 2 media that guarantee in-order packet delivery.
Definitions:
Fragments are represented as 32-bit wide words using ASCII art. Because of the Type-Length-Value encoding used (TLV) and optional fields or sizes, there is no concise way to represent all possibilities. We use the convention that ASCII art fields enclosed by vertical bars "|" represent exact bit widths. Fields with a forward slash "/" are variable bit widths, which we typically pad out to word alignment for picture readability.
TODO -- we have not adopted the Requirements Language yet.
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in RFC 2119 [RFC2119].
Fragment = FragProtocolID FragProtocolData FragProtocolID = <BeginEndFragmentsProtocolID> | (other protocols' ids) FragProtocolData = BeginEndFragmentsData | (other protocols' data) BeginEndFragmentsData = Flags FragSeqNo FragLength FragData Flags = B / E / BE / I B = <begin flag> E = <end flag> BE = <begin and end flag> I = <idle flag> FragSeqNo = 1*OCTETS FragLength = <Octets of fragment data> FragData = <Continuous octets (portion of Packet)>
A Fragment is defined as the following fields (plus any additional fields required by the wire formatting in which fragments are encoded):
The fragmentation protocol is run between a sender and a "peer", which can be one or more, potentially passive, receivers. They execute first an Initialization Protocol [init], then use a Sender Protocol [sender] and Receiver Protocol [receiver] to exchange frames.
The initialization protocol uses a reliable messages exchange to reset the the FragSeqNo to 0 on both peers. This ensures that when one or another peer restarts both peers will reset their state.
The sender breaks a packet P (typically an Interest- or Content packet in the embedding wire encoding) into one or more fragments which are tagged with monotonically increasing sequence numbers. The B, E and BE flags are used to signal the start of a fragment series (B), its end (E), or a single fragment (BE) for the given packet P.
It is advisable that the 'B' fragment contains enough information in its Fragment Data to let the receiver know the total length of the packet to be reconstructed (and size of the reassembly buffer to be allocated) and the type of the expected packet.
The receivers listen to the fragment stream and reconstruct from a valid fragment series the original packet, and reject fragments with invalid sequence numbers, flags, or validation data.
The 'I' flag allows the sender to send idle frames that do not contain any Fragment Data, but do increment the fragment sequence number. This is useful on lossy links to indicate that the sender is past the end of the previous packet in case the 'E' fragment was lost. Moreover, as a possible extension of the protocol, this allows for periodic keepalives, measuring for example link quality when there is no other traffic to send.
Whenever a peer begins operation, it must reliably reset the sequence number space. If the underlying link already ensures a complete reset of both peers, that method MAY be used. Otherwise, the method presented here SHOULD be used.
The ccnx-beginendfragment-sim [python-sim] software package is a Python simulator of the sequence number reset algorithm. It uses simple discrete event simulator to validate the reset algorithm under various conditions of delay and packet loss and node reboots.
Figures 1 - 3 show the reset state machine. In the figures, we use short abbreviations for compactness. N_L is N_LOCAL, N_R is N_REMOTE, FSN_L is FSN_LOCAL, FSN_R is FSN_REMOTE. We also abbreviate RESET as RST and RESTACK as RSTACK. Double line boxes indicate a potentially blocking state that responds to external events (timeouts or packet reception). Single line boxes indicate transient states the perform some operation.
Figure 1 shows the initial state of a system as REBOOT. REBOOT state will ignore any received packets and initialize the state variables. After rebooting, a node will be in the INIT, INIT state. From here, it may either receive a RESET message from its peer or send its own RESET message. In the first case, it proceeds to X2 (the slave state), in the second case it proceeds to X1 (the master state).
Figure 2 shows the master state, where the system sends out a RESET before receiving a RESET from a peer. In state SYNC, INIT, the node is waiting for either a RESETACK or a RESET from its peer. If it does not receive either before its timeout, it will double its timeout and send another RESET
Figure 3 shows the slave state, where the system has received a RESET from its peer before it has sent its own RESET. This puts the node in the INIT, OK state. Typically, a node will immediately send its own RESET message, though the RESETACK its sends has the same effect. This puts the node in the SYNC, OK state. One of three events can happen: a timeout to send another RESET message, receive a RESETACK or receive another RESET. Upon receiving a valid RESETACK, the node can move to the OK, OK state.

Figure 4
We expect that Ethernet will be the most common L2 technology where the proposed ICN fragmentation will be used, therefore we briefly elaborate on how fragmentation functions with the broadcast and multi-protocol nature of Ethernet.
When the fragmentation protocol is used with Ethernet, each participant uses the tuple {source mac, destination mac, ethertype} to identify a send or receive buffer and FragSequenceNumber number space.
If the fragmentation protocol is using a group address destination, each group address is considered a "peer" with its own FragSequenceNumber. For example, the MAC address 0x01005E0017AA on EtherType 0x0801 is the CCNx assigned group address for its <IP_ADDRESS> IP multicast address. Each sender would maintain a FragSequenceNumber for that peer. Each receiver would maintain a separate reassembly buffer for that group address based on the sender and ethertype.
If using other Ethernet encapsulations, such as 802.1AE MacSec, one could use a security identifier in place of the {source, destination, ethertype} tuple.
The hop-by-hop fragmentation protocol introduces a new CCNx 1.0 Packet Type called PT_FRAG and uses new fields in the Fixed Header. The hop-by-hop headers of a CCNx 1.0 fragment may be used for purposes like link quality reporting or a reliable ARQ scheme, which are out-of-scope of this document.
We describe a basic hop-by-hop fragmentation header, using bits in the Fixed Header for the fragment encoding. We also describe an extended version with variable sequence number size that puts the fragmentation header in the body of the CCNx message. This allows the fragmentation header to be signed or covered by a MIC. The extended encoding sets the 'X' flag to 1 in the Fixed Header, otherwise it is the basic encoding.
The "hop-by-hop fixed header" follows the normal conventions: The Version, PacketLength, and HeaderLength fields are as per CCNx Messages in TLV Format [CCNMessages]. The PacketType is set to PT_FRAG. However, in the packet-type dependent fields, we reserve 4 bits for flags and 20 bits for a sequence number.
The "message part" of the CCNx 1.0 fragment carries the fragment data in its own TLV block. The message part may also contain standard CCNx validation algorithm and validation bits in subsequent TLV blocks. In this way, the fragment can be covered by a CRC32C checksum or stronger validation methods.
The new TLV type T_FRAGMENT wraps the fragment bytes. It is a top-level message TLV, similar to T_INTEREST or T_OBJECT.
For sequence number reset, the new TLV types T_FRAG_RESET and T_FRAG_RESET_ACK carry the initialization message sequence number. They MUST appear in an Idle (I) frame. A packet MUST NOT have T_FRAGMENT if it has one of these fields. A single packet may have both a T_FRAG_RESET and a T_FRAG_RESET_ACK. These fields appear in the CCNx message section. It is RECOMMENDED to use a 64-bit sequence number, though an implementation MAY use any length appropriate to the media.
T_FRAG_RESET and T_FRAG_RESET_ACK may be in either basic header or extended header packets. In extended header format, the T_FRAG_HEADER element MUST be length 1, which conveys only the flags.

The FragSequenceNumber follows Serial Number Arithmetic [RFC1982] for a 20-bit serial number. This means we have 19 bits of "valid" sequence number space, or 524,288 fragments. The packets per second for a 10 Gbps link with 1500 bytes Ethernet frames is 833,333 packets per second. Therefore, the 20-bit sequence number space allows for 629 milliseconds of frames.
In CCNx 1.0, the maximum encapsulated length is 64 KB -- which requires under 50 PT_FRAG frames of 1500 bytes, depending on the HeaderLength and validation options. So the valid sequence number space (when e.g. used over Ethernet) is approximately 10,500 maximum size (network protocol) packets.
If a PT_FRAG packet has optional hop-by-hop headers, the implementation should pass the fragment to the appropriate subsystem to process those headers before discarding the fragment.
The Extended encoding (X=1) moves the fragment header fields (= flags and sequence number) to the CCNx packet's message part, so they are covered by any ValidationAlgorithm used on the packet. It also allows for variable length sequence numbers. In the example shown below, there is a 7-byte (56-bit) sequence number.
The Extended encoding also allows different fragmentation protocols to co-exist by changing the opening TLV type from T_FRAG_HEADER to a new type.
The first 8 bytes of the first fragment are the FixedHeader of the encapsulated Packet, so one may learn the overall length of the Packet from that FixedHeader.

We present a complete example of the basic fragment encoding for a 2KB Content Object for 1500 byte frames according to the protocol described in this draft (with clear X-flag). The original 2KB packet also has an RSA signature, but this cannot easily be used for integrity checking as the receiver may not have the appropriate key and it is an expensive operation. We therefore chose to use a CRC32C validator on each fragment. The Content Object has the name ccnx:/abcd. First, the original 2000 byte packet is shown in entirety.

The 2000 byte packet will be fragmented into two pieces. In the first fragment, there is 28 bytes of overhead (fixed header 8, T_STD_FRAGMENT 4, validation 16), so the fragment's payload size is 1472 bytes. In the second packet, the T_FRAGMENT block carries the remaining data 528 bytes, hence the overall packet size is 556 bytes due to the same 28 bytes of overhead. We used FragSequenceNumber "0" and "1" for the two fragments.

A sender/receiver pair may multiplex non-fragmentation frames on the same link. For example, in CCNx 1.0, there may be some PacketType PT_FRAG frames and some plain PT_INTEREST or PT_CONTENTOBJECT frames on the same link between the same pairs. PT_FRAG frames are considered independently of other frames between the pair.
Because each CCNx 1.0 datagram with a Fixed Header has all information needed for framing, two peers may pack multiple CCNx 1.0 datagrams in to one Layer 2 frame. For example, if there are several small Interests queued back-to-back, they could be encapsulated in a single Ethernet frame, up to the maximum Ethernet payload.
At the extreme, a peer may use fragmentation for all packets and completely pack each Layer 2 frame. The tail fragment would be cut off at whatever byte length fits the remaining Layer 2 frame.
interest1(200B) content1(3500B) interest2(200B) content2(500B)
[frag(interest1,200B), frag(content1, 1276B)] [frag(content1, 1488B)] [frag(content1, 236B), frag(interest2, 200B), frag(content2, 500B)]
Example: Assume that the outgoing queue for a specific peer has the following four packets to be sent:
The Begin-End fragmentation protocol described in this draft extends the NDN link protocol v2 packet format (NDNLPv2). Note that this extension is not an official part of the NDN suite, at this point in time.
NDNpacket ::= Interest | Data | NDNLP NDNLP ::= NDNLP-TYPE TLV-LENGTH NDNLPhdrFields* NDNLPfragment? NDNLPhdrFields ::= BeginEndField | (other NDNLP header fields) BeginEndField ::= BEGIN-END-FIELD-TYPE TLV-LENGTH BYTE BYTE+ NDNfragment ::= NDN-FRAGMENT-TYPE TLV-LENGTH BYTE+
NDNLPv2 packets have a start type NDNLP-TYPE which distinguishes them from the classic Interest and Data packets. Inside the NDNLPv2 TLV structure, a sequence of NDNLPv2 header fields precede the payload (fragment data) which is introduced by the type value NND-FRAGMENT-TYPE.
The extension for the "begin-end" fragmentation scheme relies on a new header field with type value NDN-BEGIN-END-FIELD-TYPE: The presence of this field marks a NDNLPv2 packet as a "begin-end" fragment. The field's value is 1 to 8 bytes long and consists of 2 flag bits (most-significant bits) plus a sequence number (remaining less-significant bits).
For a sender/receiver pair and for a given direction, the value of the BeginEndField is of constant size. But depending on the start configuration, different sizes can be chosen for operations, both in time and for the different directions.
In the smallest possible setup (e.g. sensor network with very small MTUs), the BeginEndField can have a one-byte value (2 flag bits plus 6 sequence number bits). For Ethernet, it it is recommended to use a 3-byte value (2 flag bits plus 22 sequence number bits).
An idle fragmentation frame is encoded as a NDNLP packet with a Begin-End Field but no NDNfragment element. Both the B- and the E-flags should be set to 1 in this case.
The frist bytes of the first fragment are the outermost NDN TLV of the encapsulated Packet. One may learn the overall length from the the outermost TLV length.
We present an example of the basic fragment encoding for a payload of size larger than 253 Bytes and less than 64KB.
1 2 3 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 +---------------+---------------+---------------+---------------+ | type=NDNLP | len=N+9 | +---------------+---------------+---------------+---------------+ | type=BeginEnd | len=3 |B|E| FragSequence... | +---------------+---------------+---------------+---------------+ | ..Number | type=Fragment | len=N | +---------------+---------------+---------------+---------------+ | | FragmentData (N bytes) ... / +---------------+---------------+---------------+---------------+ / / +---------------+---------------+---------------+---------------+ / | +---------------+
A sender/receiver pair may multiplex non-fragmentation frames on the same link. For example, in NDN, there may be some NDNLP frames and some plain Interest or Data frames on the same link between the same pairs. NDNLP frames are considered independently of other frames between the pair.
NDNLP does not allow for frame packing: A frame contains only one out of the three Interest, Data and NDNLP packet types.
NDNLP-TYPE 0x64 // official, might change BEGIN-END-FIELD-TYPE 0x5c // inofficial NDN-FRAGMENT-TYPE 0x52 // official, might change
This document adds new values to the CCNx Packet Type Registry and CCNx Message Registry.
Value CCNx Packet Type Definition ---- ------------------------ ---------- 4 PT_FRAG See Section 4
Value CCNx Message Type Definition ---- ------------------------ ---------- 5 T_FRAGMENT See Section 4 16 T_FRAG_HEADER See Section 4 17 T_FRAG_RESET See Section 4 18 T_FRAG_RESET_ACK See Section 4
This protocol has no security mechanisms and is vulnerable to injection attacks by other devices on the same physical link as the fragmentation peers. One should use a secure Layer 2 protocol, such as 802.1AE (MacSec) to prevent such attacks.

Hello ,
I’m trying AtomicDEX with iOS and I can’t enter the new created wallet. When I introduce the password I’m invited to create a 5 number passcode again, and then again to the locked wallet.
Thanks
psyfont11-Sep-19 06:36 PM
Ok, I finally skip it (5 number code creation screen) and able to enter the wallet just sliding with finger to the right on the top bar. I didn’t touch the red button on the left side, it was sending me to the selection wallet screen...
No. Same again
TonyL11-Sep-19 07:11 PM
Hello! Actually pin code have 6 digits. Maybe 6th doesnt fit your screen. What Iphone model are you using @psyfont ?

I used a seed to an address containing kmd when i installed atomicdex on My Phone, but No kmd is showing in the wallet.
Shouldnt it show the balance of the address?
gcharang12-Sep-19 06:13 AM
@lollipop search the address in explorer: kmdexplorer.io
lollipop12-Sep-19 06:15 AM
The wallet does not have the same address as the one with the kmd.
Okay
Did I type the seed wrong then?
gcharang12-Sep-19 06:17 AM
if you selected "custom seed" then there is a possibility that you have input a wrong seed
lollipop12-Sep-19 06:17 AM
I did
So i uninstall and try again right?
gcharang12-Sep-19 06:18 AM
no need to uninstall
just select "restore" in the welcome screen and give it a different name
lollipop12-Sep-19 06:18 AM
Okay
Thx
gcharang12-Sep-19 06:18 AM
you can also delete the wrong wallet from "settings"
if you don't select "custom seed", the wallet will only allow you to proceed if you enter a seed that was created by atomicDEX
lollipop12-Sep-19 06:20 AM
Aaah
Its not a wallet created by atomicdex tho
gcharang12-Sep-19 06:22 AM
where was the seed created?
agama?
lollipop12-Sep-19 06:22 AM
Yew
Yes
gcharang12-Sep-19 06:23 AM
then you should select "custom seed" and enter the words properly. click the eye icon to see the words you are entering
and don't add extra spaces
lollipop12-Sep-19 06:24 AM
I did. But must have missed something. Ill just try again. Np.

Thx
gcharang12-Sep-19 06:27 AM
did that work?
lollipop12-Sep-19 06:30 AM
Havnt tried. Making breakfast

Will try in 15 min and get back to you
gcharang12-Sep-19 06:43 AM
@wanda if you forgot the password, you could use the "restore" option and use the seed words that you have backedup when creating the wallet(edited)
wanda12-Sep-19 06:53 AM
it worked gcharang and i backedup my password this time
is eth in atomicdex a smart contract or direct transfer?
gcharang12-Sep-19 08:02 AM
@IamTrader it uses a smart contract
what do you mean by direct transfer?
IamTrader12-Sep-19 08:03 AM
@gcharang ah okay, coz the exchange i use it says it does not support smart contract just direct transfer
gcharang12-Sep-19 08:06 AM
@IamTrader the receiving address for ETH in atomicDEX is a normal address
so it is a direct transfer
what I said previously is that, for atomic swap involving ETH, we use smart contracts
so you should be able to withdraw to your atomicDEX ETH address(edited)

Really, minimum BTC buy is .00777? Is this a bug?
dudezmobi12-Sep-19 09:42 AM
Looks like it
TonyL12-Sep-19 10:02 AM
@benzo365 Hi! It's not a bug - minimal swap amount is 0.00777 determined by protocol and the same for all coins. I'm agree that it's quite high amount in USD equialent. But from another side it's better to trade huge amounts of BTC because of tx fees.
Privatoshi12-Sep-19 10:22 AM
$80 btc minimum for buys
phideas12-Sep-19 10:24 AM
no one should complain, btc is digital gold after all. heavy and expensive. by design.(edited)
Privatoshi12-Sep-19 10:26 AM
well since you said no one should complain, then u must be right, naturally.
phideas12-Sep-19 10:28 AM
i don't have to be right, btc is as it is on layer one. not realy suitable for small tx.(edited)
Privatoshi12-Sep-19 10:33 AM
Which set of layers we referring to?
How about the LN?
phideas12-Sep-19 10:36 AM
Yes, LN is designed to do micro tx with BTC. But it is different tech, L2 solution. Not suited for komodo atomic swaps afaik,
benzo36512-Sep-19 10:42 AM
In my opinion a DEX shouldn't have restrictions like this
1
phideas12-Sep-19 10:56 AM
i agree $80 is a bit overkill for a min. amount per swap. btc is currently capable to do it cheaper, but otoh btc fees can change rapidly as "number go up"

wl12-Sep-19 03:32 PM
I had some rewards to claim, but after sending some kmd to another wallet I have no more rewards to claim, is that how it's supposed to behave or is a bug? If I'm correct, on the agama wallet this was possible (send some and still have my previously accumulated kmd to claim)...
Oszy12-Sep-19 03:39 PM
when you send it claims it for you(edited)

ca33312-Sep-19 03:39 PM
@wl that is a feature - when sending a TX the reward is automagically claimed. You can actually check your transaction on the blockexplorer and will see the reward.
wl12-Sep-19 03:41 PM
Thanks for the quick answer, I know it's like that on the agama I didn't know the AtomicDex had it too
1
ca33312-Sep-19 03:43 PM
Thanks for the feedback - i will take it as a feature request (improvement) - we will add a logic that checks potential rewards before sending a transaction and informs the user about the automagic claiming and corresponding amount...

how much liquidity is on kmd/btc?
groundhog12-Sep-19 04:19 PM
is that intentional, that when prompting the wrong pw i can not use the touchfuction on my mobile to place the cursor, instead i need to use "del" and go all the way back like in a terminal?
also i have problems trading mortys and ricks, seems i cant get orders through for some reason
if i try trading 1 morty for 2 ricks, the trade is accepted first but then doesnt show up neither in orders nor history
i can only buy from existing orders
from the "orderbook"
dan.12-Sep-19 04:22 PM
side note, stuck on connecting. deleted app, deleted cache, didnt help
groundhog12-Sep-19 04:23 PM
does logging of delete the cache?
or deleting wallet?
dan.12-Sep-19 04:24 PM
if youre on android go to apps, then atomicdex and delete cache
but doesnt help me
groundhog12-Sep-19 04:24 PM

trying to reinstall
those ricks and mortys are only for test purposes no? it doesnt matter if i burn the all right?
dan.12-Sep-19 04:28 PM
yeah, junk coins
groundhog12-Sep-19 04:31 PM

NEW EDEN A Film Review Copyright Dragan Antulov 2001
Fans of BLAKE'S SEVEN would probably think of the opening episode of their favourite TV show being inspiration for the opening shots of NEW EDEN, 1994 science fiction film directed by Alan Metzger. The film begins with huge spaceship that carries prisoners to distant planet that serves as a prison colony. Upon arrival on the desert planet called Earth 21-523, the prisoners are unceremoniously dumped and left to fend for themselves. Most fall prey to the bandits or try to join their ranks, but young idealistic engineer Adams (played by Stephen Baldwin) chooses another path and tries to improve life of small nomadic tribe by showing them benefits of irrigation. Such efforts would, however, lead to the conflict with some of his former friends.
NEW EDEN is made with small budget, but it starts looking really cheap only when we realise that the distant alien planet is desert-like not only to due to the lacking budget, but also due to the lacking creativity of their makers. After a brief intro, NEW EDEN starts resembling multitudes of cheap post-apocalyptic action films made in 1980s after success of MAD MAX. The impression is even worse when we take into account ESCAPE OF ABSALOM, similar futuristic prison movie that had the decency of employing somewhat different setting. However, Dan Gordon's script manages to overcome at least some post-apocalyptic cliches - the protagonist is idealistic intellectual instead of Rambo-like killing machine, and Stephen Baldwin seems more suitable for playing the former type of characters. Another bright spot in this film is Tobin Bell in rather interesting role, so different from many psychopaths and villains he had to play during his career. But his efforts would won't improve the general impression of this film. Although not among the worst example, NEW EDEN is one of those cheap science fiction films that often give bad name to the entire genre.
RATING: 3/10 (+)

We have big plans for HTML5 test. Our latest additions are a new server backend
that automatically collects the test results and creates some extensive reports based on the
collected data. But we have some more ideas for the future.
These additions do take a lot of time, so if you think HTML5 test is a great resource, consider
donating.
Donate using Paypal
In order to pay for hosting and further development of the HTML5 test we allow a small number of ads
on two positions of the main page. We prefer ads that are related to HTML5 or web development.
Ads on the HTML5 test are exclusively sold by BuySellAds.
A lot of our data is crowd sourced, but in certain cases we need access to the actual browser running on
the actual device. For this purpose we have build a testing lab with not only new devices, but also
older devices for testing historic versions.
If you have a new or used device you want to donate to our lab, please contact me on
Github or Twitter.


Ah! You wish to have a Dualsword made? That is our specialty! In fact, we can make every type of Dualsword except the A-grade!
If there's anyone better than us, it could only be the legendary Blacksmith of Mammon!
You don't have to bring me a stamp, either.
Just bring me the swords you want combined as well as Stones of Purity as a fee.
Make sure the swords are either Regular, Standard or Rare.
Regular weapons must be combined with other Regular weapons, Standard weapons must be combined with other Standard weapons, and Rare weapons must be combined with other Rare weapons. A Rare Dualsword can only be made using swords above grade B, which is the lowest grade we work with.
Remember that if you invest some kind of a skill in a weapon, you can't combine it with another.
Remember as well that an Enchanted weapon loses its effect once it is combined with another.
Which Dualsword would you like? Select one now.

[gecode-users] Valid Domain Recomputation
Efstratios Kalogirou
efkalog at gmail.com
Mon Aug 7 10:50:24 CEST 2006
Hi all,
I am using Gecode to create a function that receives a variable x and a
value v for that variable from the user and returns only the valid values
for all the variables (some of them are excluded because of constraint
propagation after the assignment x=v). What I am doing is :
1. Assign variable x value v
2. For all the variables i of this new space which I call FATHER SPACE
3. For all the values j of each variable
4. Clone FATHER to TEMP Space and assign inside TEMP variable i= value
j
5. Get the Status of the TEMP Space. if SS_SOLVED do nothing, if
SS_FAILED post i!=j in the FATHER SPACE. If SS_BRANCH I am using a search
engine to check weather there is a solution or not. If there is, do nothing,
otherwise post again i!=j in the FATHER SPACe.
6. Delete TEMP
By posting i!=j I manage to exclude from my father space the values that are
no longer valid. This works fine, but steps 1-5 are repeated many times and
each time I perform this valid domain check, i have to go through all the
variables and all the values, copy the father space to temp, and get the
status of the temp. This slows things down a lot and I have been wondering
if there is a faster way to do this. Any ides?
Best,
Stratos Kalogirou

Declares that the current module will not define any more key flags.
tf.compat.v1.app.flags.disclaim_key_flags
tf.compat.v1.flags.disclaim_key_flags()
Normally, the module that calls the DEFINE_xxx functions claims the flag to be its key flag. This is undesirable for modules that define additional DEFINE_yyy functions with its own flag parsers and serializers, since that module will accidentally claim flags defined by DEFINE_yyy as its key flags. After calling this function, the module disclaims flag definitions thereafter, so the key flags will be correctly attributed to the caller of DEFINE_yyy.
After calling this function, the module will not be able to define any more flags. This function will affect all FlagValues objects.

Classes in Ruby, like other programming languages, group related pieces of information together in a meaningful way. The variable and actions provided by each class will make you code more efficient to type and run. In the example I will use it should become clear how classes are used and why they are important.
Remember getting your class schedule the first time you had six or seven different periods in school? For me it was in sixth grade. The seven classes on the list all shared the same common information:
class Class attr_reader :subject, :teacher, :room attr_accessor :days_of_week, :start, :end def initialize(subject, teacher, room) @subject = subject @teacher = teacher @room = room end def add_students(students) @students = [] students.each{|s| @students << s} end def set_schedule(start, end, days_of_week) @start = start @end = end @days_of_week = days_of_week end end
With these few lines of code you can create all the Classes you want from this single class. You don't have to create the list of variables for each one. Just create an instance of the Class object. Set the teacher, subject and room number to get a new course. That is the initialize method. Now you have an object that is an instance of the class Class. This class has methods that will let you add students and set the schedule represented by the other def code blocks. Each instance of a Class will also be able to tell you what all the information is. The attr lines at the top give you the ability to read or write each variable in the instance of the class.
By simply calling a few lines of code you can create a new math class. math_class = Class.new("math","Mrs. Trout", 205) math_class.set_schedule("9:00 AM", "9:50 AM", ["M", "T", "W", "Th"]) math_class.add_students([Ryan, Ted, Sally, Jennifer, Bill]) I hope by now you can see how classes make it easier to create Classes.


Panzoom was created so that images can be zoomed and the zoom location could be paused. This was needed for image transcribing purposes. It was also intended to be simple. All you need is a container div and panzoom does the rest. Only 1 image size is needed. It also has built-in, client-side rotation support. This was useful for scanned documents that weren't always the correct perspective.
panZoom(imageFile, container, rotationAngle);
Usage Example:

PanZoom requires JQuery and JQuery Mousewheel libraries
Tested in Chrome, Firefox, Safari, Edge
