From an API point of view, there are two basic requirements that every replicated application must meet:
It must be a transactional application.
It must use a specific form of the Environment handle, which you get by using the ReplicatedEnvironment class.
Beyond that, there are some additional requirements in terms of exception handling that your application should perform.
The transactional nature of your replicated application is described in Transaction Management. This chapter discusses replicated environments and the exceptions unique to exceptions in detail.
Every electable or secondary node manages a single replicated JE environment directory. The environment follows the usual regulations governing a JE environment; namely, only a single read/write process can access the environment at a single point in time.
Usually this requirement is met naturally, because usually each node in a replicated application is also operating on a machine that is independent of all the other nodes. However, in some test and development scenarios, this one node to one machine rule might not be met, so the bottom line is that you need to make sure that no two processes are ever attempting to manage the same environment.
An application can access a replicated JE environment directory using a read only Environment handle. The usual semantics of read only non-replicated Environment handles apply in this case. That is, the application can view a snapshot of the replicated environment as of the time the Environment handle was opened, through the Environment handle. An application can therefore open a ReplicatedEnvironment handle in one process, and concurrently open read only Environment handles in other processes. Any changes subsequently made to the replicated environment, either by virtue of the node being a Master, or due to a replay of the replication stream (if the node is a Replica), are not accessible through the read only Environment handles until they are closed and reopened.
Normally you manage your JE environments using the Environment class. However, to provide for the underlying infrastructure needed to implement replication, your JE HA application must instead use the ReplicatedEnvironment class, which is a subclass of Environment. Its constructor accepts the normal environment configuration properties using the EnvironmentConfig class, just as you would normally configure an Environment object. However, the ReplicatedEnvironment class also accepts an ReplicationConfig class object, which allows you to manage the properties specific to replication.
The following is an example of how you instantiate a ReplicatedEnvironment object. Note that there are some differences in how this is used, depending on whether you are starting a brand-new node or you are restarting an existing node. We discuss these differences in the next section.
For a general description of environments and environment configuration, see the Getting Started with Berkeley DB Java Edition guide.
EnvironmentConfig envConfig = new EnvironmentConfig(); envConfig.setAllowCreate(true); envConfig.setTransactional(true); // Identify the node ReplicationConfig repConfig = new ReplicationConfig(); repConfig.setGroupName("PlanetaryRepGroup"); repConfig.setNodeName("Mercury"); repConfig.setNodeHostPort("mercury.example.com:5001"); // This is the first node, so its helper is itself repConfig.setHelperHosts("mercury.example.com:5001"); ReplicatedEnvironment repEnv = new ReplicatedEnvironment(envHome, repConfig, envConfig);
You configure a JE ReplicatedEnvironment handle using two different configuration classes: EnvironmentConfig and ReplicationConfig. Your usage of EnvironmentConfig is no different than if you were writing a non-replicated application, so we will not describe its usage here. For an introduction to basic environment configuration, see the Getting Started with Berkeley DB, Java Edition guide.
The ReplicationConfig class allows you to configure properties that are specific to replicated applications. Some of these properties are important in terms of how your application will behave and how well it will perform. These properties are discussed in detail later in this book.
To an extent, you can get away with ignoring most of the configuration properties until you are ready to tune your application's performance and behavior. However, no matter what, there are four properties you must always configure for a ReplicatedEnvironment before opening it. They are:
Group Name
The group name is a string that uniquely identifies the group to which the node belongs. This name must be unique. It is possible to operate multiple replication groups on the same network. In fact, a single process can even interact with multiple replication groups, so long as it maintains separate replicated environments for each group in which it is participating.
By using unique group names, the JE replication code can make sure that messages arriving at a given client are actually meant for that client.
You set the group name by using the ReplicationConfig.setGroupName() method. Note that if you do not set a group name, then the default GROUP_NAME value is used.
Node Name
This name must be unique to the replication group. This name plus the replication group name uniquely identifies a node in your enterprise.
You set the node name by using the ReplicationConfig.setNodeName() method.
Host
The host property identifies the network name and port where this node can be reached. Other nodes in the replication group will use this host/port pair to establish a TCP/IP connection to this node. This connection is used to transfer data between machines, hold elections, and monitor the status of the replication group.
You provide the host and port information using a string of the form:
host:[port]
The port that you provide must be higher than 1023.
You set the host information by using the ReplicationConfig.setNodeHostPort() method. Note that if you do not set a node host, then the default NODE_HOST_PORT value is used.
Helper Host
The helper host or hosts are used by a node the very first time it starts up to find the Master. Basically, this string should provide one or more host/port pairs for nodes who should know where the Master is.
One of the nodes that you provide on this string can be the current Master, but that is not required. All that matters is that the hosts identified here can tell a new node where the current Master is.
If the brand new node is an electable node and cannot find a Master, it will initiate an election. If no other electable nodes are available to the new node, and the current node is specified as the only helper host, then it will elect itself as Master. If the current node is truly the very first electable node starting up in the replication group, then self-electing itself to be the Master is probably what you want it to do.
However, if the current node is not the very first node starting up in the replication group, then a misconfiguration of this property can cause you to end up with multiple replication groups, each with the same group name. This represents an error situation, one that can be very difficult to diagnose by people who are inexperienced with managing replication groups. For this reason, it is very important to make sure the hosts identified on this string do NOT identify only the local host except when creating the first node.
On subsequent start ups after the very first startup, the node should be able to locate other participants in the replication group using information located in its own database. In that case, the information provided on this string is largely ignored unless the current node has been down or otherwise out of communication with the rest of the group for so long that its locally cached information has grown stale. In this case, the node will attempt to use the information provided here to locate the current Master.
You set the helper host information by using the ReplicationConfig.setHelperHosts() method.
When configuring and instantiating a ReplicatedEnvironment object, you should usually configure the environment so that a helper host other than the local machine is used:
EnvironmentConfig envConfig = new EnvironmentConfig(); envConfig.setAllowCreate(true); envConfig.setTransactional(true); // Identify the node ReplicationConfig repConfig = new ReplicationConfig(); repConfig.setGroupName("PlanetaryRepGroup"); repConfig.setNodeName("Jupiter"); repConfig.setNodeHostPort("jupiter.example.com:5002"); // Use the node at mercury.example.com:5001 as a helper to find the rest // of the group. repConfig.setHelperHosts("mercury.example.com:5001"); ReplicatedEnvironment repEnv = new ReplicatedEnvironment(envHome, repConfig, envConfig);
Note that if you are restarting a node that has already been added to the replication group, then you do not have to supply a helper host at all. This is because the node will already have locally stored host and port information about the other nodes in the group.
EnvironmentConfig envConfig = new EnvironmentConfig(); envConfig.setAllowCreate(true); envConfig.setTransactional(true); // Identify the node ReplicationConfig repConfig = new ReplicationConfig("PlanetaryRepGroup", "Jupiter", "jupiter.example.com:5002"); ReplicatedEnvironment repEnv = new ReplicatedEnvironment(envHome, repConfig, envConfig);
However, if you are starting the very first node in the replication group for the very first time, then there is no other helper host that the node can use to locate a Master. In this case, identify the current node as the helper host, and it will then go ahead and become a replication group of size 1 with itself as a Master.
Do this ONLY if you are truly starting the very first electable node in a replication group for the very first time.
EnvironmentConfig envConfig = new EnvironmentConfig(); envConfig.setAllowCreate(true); envConfig.setTransactional(true); // Identify the node ReplicationConfig repConfig = new ReplicationConfig("PlanetaryRepGroup", "Jupiter", "jupiter.example.com:5002"); // This is the first node, so the helper is itself. repConfig.setHelperHosts("jupiter.example.com:5002"); ReplicatedEnvironment repEnv = new ReplicatedEnvironment(envHome, repConfig, envConfig);

The sight of the tumblers restored Bob Sawyer to a degree of equanimity which he had not possessed since his interview with his landlady. His face brightened up, and he began to feel quite convivial.

The extrema of system integration
There seems to be a lot of confusion on this subject, so I decided to give my very opinionated view on the subject.
There are 2 extrema in how to handle integration between different systems:
Implicit integration: Fred George’s micro-service architecture
The concept of micro-service architecture is “Antifragile” applied to software architecture: have lots of versions of very tiny micro-services running, without precisely knowing which service does what.
This comes down to an approach where you publish all messages to a single enterprise bus, and then several children act as proxies for this message bus.
You don’t care about how all these services work, but monitor the state of the system. If a problem occurs, you can usually just write a new service that solves the issue. This implies that you might have services running that no longer provide actual value, and comes down to this single fact:
You don’t care how the system works, as long as it works!
As you can imagine this relies mostly on investing in your monitoring.
The advantage is that integrating new things, replacing services and services that fail are non-events, as you have these happening all the time, but the disadvantage is that you don’t have an explicit map about how the system works, you just need to look everywhere and browse around a lot.
Explicit integration: Alistair Cockburn’s Hexagonal pattern + explicit interfacing
On the other side of the spectrum, you can do hexagonal architecture with very explicit integration handling. Both incoming and outgoing things go through explicit interfaces using adapters and ports. This is like CQS - or even CQRS - applied to system integration.
Whenever one would cross an AR instance boundary, one might do this through a plethora of interfaces:
SharedKernel.IPublish[SomeBC]Events
SharedKernel.IConsume[SomeBC]Events
SharedKernel.IQuery[SomeBC]State
[SomeBC].IQuery[SomeAR]State
[SomeBC].IPublishEvents
[SomeBC].IConsumeEvents
This is typically an explicit interface or a protocol, and your domain model should access these directly.
If you opt for the extreme side of this explicit approach, this would imply that you do not have any untyped contracts at all (So no method exposing things like message buses etc., every single method exposed by this interface would expose exactly one single type of message/functionality, so no publish(object message)
, but a publish(SomeCertainMessageType a)
.)
Advantages are the transparency of the system (as everything is explicit in code), but the disadvantage is that this does add some overhead.
Conclusion
So there you have it: the two extrema of software integration. Both have their advantages and disadvantages. The thing I would like to mention the most, is that one should never forget about Conway’s law, i.e. system models will mimic the organisation’s model they were built with.
Take a look at the organisation culture you have, and base your architecture decision on that.
Other than that, be pragmatic. Executing multiple AR updates in a single UOW might not be a problem, if you are aware about it. It’s all about easy vs simplicity in the end.
Technical debt only becomes debt when “the loan” is claimed. If you have an ugly hack, but it works, and you’ll never have to change it, so be it. However, one can always come in to claim the loan (one or multiple times), you need to be aware of that. In the end it is all about risk management.
This whole story actually shows a lot of similarities to the extrema of management IRL: output-driven management vs. micro-management.

Here we explain how to use the web UI to create and manage emulations and view their results.
Note: For best results only use the Web UI on an up to date browser (may not function as intended on an out of date or older browser)
Provided that the API is running, the web UI will be accessible at
http://[COCOMA API IP]:[COCOMA API PORT]/index.html
The COCOMA API IP refers to the IP of the interface on which the API have been started. The page is compatible with Chrome, Firefox and Safari web browsers, while it is not with Internet Explorer. The page will automatically load in available emulators, distributions and resources. It will detect which distributions and resources are compatible with the given emulator so that the user needs not worry about creating XML the framework cannot process. Any emulations which already exist will also be displayed in the right hand bar.
Each emulation requires a name and at least one distribution, although as many distributions as required can be added. Each distribution requires a name and all required fields to be filled, this data will vary as per the emulation, distribution or resource selected. Some help is provided to explain what each of the arguments are and (if relevant) what their units are. Distribution windows can be minimized for overall readability or removed entirely (not added to the emulation) by clicking the ‘x’ in the top right corner:
Where possible, help has been added for each distribution parameter. This can be viewed by hovering over the ? beside a parameter; This should display a pop-up with some help and the units (if relevant) of that parameter
After the distributions have been created and specified, there is an option to enable or disable logging. Enabling logging give 2 more options, the frequency in seconds and the level, which dictates the amount of output the logs will contain. Below this is the option to enable or disable the message queue followed by various parameters allowing for it’s setup
Once all the parameters are set there are two options; run the emulation right away by clicking the Run now button, or schedule the emulation to begin running at a set time in the future by clicking the Run at button:
Any existing emulations in your system will be listed on the right hand side of the screen. The UI also displays the total number of runs, how many of those failed and the current state of the emulation (Pending Execution, Running, Executed, Unexecuted Run(s) or Failed Run(s)). Hovering over the emulation name will display the information on that emulation in a popup.
Clicking the small download icon to the right of each emulation will prompt the download of a zip file to your system. This zip file contains the .xml used to create the emulation as well as .csv files with the system logs and the logs for that specific emulation.

Floating on Trash
Sun | Submitted by: lodri
Man has failed marriages. Man collects plastic bottles. Man builds island
with them and anchors it off the coast of Mexico: "A British carpenter who
dreamed of living on a private sunshine isle built himself one using 250,000
plastic bottles. Richie Sowa spent four years making the floating Spiral
Island, which measures 66ft by 54ft, weighs 60 tons and has three
sandy beaches."

Spelling bee freaks
New York Times | Submitted by: lodri
"Of all the rituals the Goldsteins observe, and as Orthodox Jews, they
observe many, this is one of the most important and perhaps the most
personal. It is a reminder of what binds them, and defines them, as a family."

Big deal, a spelling bee. They're clueless. I give up on them. What can
I tell you? Most people nowadays are wacko anyway."

College males: trouble understanding condoms
Wire Services | Submitted by: Laura Elaine Wilson
"In a survey of 158 heterosexual males who used a condom in the
previous 3 months, 30% said they had initially put the condom on
upside down and had to flip it over. Forty percent said they did
not leave space at the tip of the condom after they put it on, a
technique that reduces the risk of breakage, according to the
report in the August issue of the journal Sexually Transmitted Diseases."

The Albuquerque Isotopes
Wire Services | Submitted by: Rufferto
"Doh! Homer Simpson's worst fears are coming true, sort of. As you may
recall, Simpson went on a hunger strike last year when it was revealed on
the cartoon series that his beloved baseball team, the Springfield Isotopes,
were moving to Albuquerque to become the Albuquerque Isotopes. Now it's
happening for real. The new team that will take the field in Albuquerque next
year will be called the Isotopes in homage to Homer."

Botulism thriving in Lake Erie
Toronto Star | Submitted by: Son of Benway
"Large numbers of fish and fish-eating waterfowl have been washing up
dead on the north shore of Lake Erie this week as botulism bacteria make
their way up the food chain through exotic species such as zebra mussels
and goby fish... Cottager Garth Hagey says the beach would be unusable
without regular cleanups. His parents have been collecting and burying
nearly 100 fish and birds a day."

Vocabulary word lands teacher in deep shit
Wire Services | Submitted by: f00f
Political correctness gone awry again:
"Last week, Stephanie Bell, a teacher at Williams Elementary School,
said she used the word "niggardly," which means stingy or miserly, during a
discussion about literary characters. Parent Akwana Walker, who is black,
protested the use of the word, saying it offended her because it sounds
similar to a racial slur... failure to comply with the directives in the
letter, which included sensitivity training, would lead to further action."

This traditional Italian seafood pasta dish of clams with chilli, garlic and white wine is great for a date night recipe.
Rinse the clams well and scrub if necessary in cold water. Discard any with cracked or damaged shells and those that don’t close when tapped on the edge of the sink. Place the rest in a large bowl. Cover with lots of cold water and leave to stand for 20 minutes to give the clams a chance to dislodge any sand that might be present inside the shells.
Half-fill your largest saucepan or flame-proof casserole with cold water, add the salt and bring to the boil. Score a cross through the skin in the base of the tomato and lower gently into the bubbling water. Leave for 30 seconds and then remove with a slotted spoon or tongs, place on a chopping board and leave until cool enough to handle.
Return the water to the boil and gradually add the spaghetti, pushing down and separating the strands as it enters the water. Stir well as it begins to soften and return to the boil. Cook for 10 minutes, or according to the packet instructions, until just tender (al dente).
While the spaghetti is boiling, remove the clams from the bowl they have been soaking in with a slotted spoon - so that any sand is left at the bottom of the bowl – rinse in a colander and transfer to a clean bowl.
Heat the oil in a large non-stick, lidded sauté pan or wide-based saucepan. Very gently fry the garlic, shallot and chilli for five minutes, or until well softened, stirring regularly. Slip the skin off the tomato and discard. Cut the tomato into quarters, throw away the seeds, and cut the tomato flesh into 1cm/½in dice.
Increase the heat under the pan to high, add the tomatoes and cook for a minute, stirring. Pour the wine into the pan and bring to a simmer. Add the clams and stir well. Cover with a tight-fitting lid and cook for one minute. Carefully give the pan a good shake, holding the lid firmly in place, and cook for two minutes more.
Remove the lid, stir the clams with a wooden spoon and cook for a further 30-60 seconds, or until the clams have all opened. Remove the pan from the heat, pick through the clams and discard any that haven’t remained shut. Season the clam mixture well with salt and freshly ground black pepper.
Drain the pasta in a large colander and return to the saucepan. Tip all the clam mixture into the saucepan, scatter over the chopped parsley, season with ground black pepper and toss well together (Tongs or a large spoon and fork work well for tossing.) Check the seasoning and serve.

| #define mpack_reader_init_stack | ( | reader | ) |
Initializes an MPack reader using stack space as a buffer.
A fill function should be added to the reader to fill the buffer.
| #define MPACK_READER_MINIMUM_BUFFER_SIZE 32 |
The minimum buffer size for a reader with a fill function.
| typedef void(* mpack_reader_error_t) (mpack_reader_t *reader, mpack_error_t error) |
An error handler function to be called when an error is flagged on the reader.
The error handler will only be called once on the first error flagged; any subsequent reads and errors are ignored, and the reader is permanently in that error state.
MPack is safe against non-local jumps out of error handler callbacks.
Bear in mind when using longjmp that local non-volatile variables that have changed are undefined when setjmp() returns, so you can't put the reader on the stack in the same activation frame as the setjmp without declaring it volatile.
You must still eventually destroy the reader. It is not destroyed automatically when an error is flagged. It is safe to destroy the reader within this error callback, but you will either need to perform a non-local jump, or store something in your context to identify that the reader is destroyed since any future accesses to it cause undefined behavior.
| typedef size_t(* mpack_reader_fill_t) (mpack_reader_t *reader, char *buffer, size_t count) |
The MPack reader's fill function.
It should fill the buffer as much as possible, returning the number of bytes put into the buffer.
In case of error, it should flag an appropriate error on the reader.
| typedef void(* mpack_reader_skip_t) (mpack_reader_t *reader, size_t count) |
The MPack reader's skip function.
It should discard the given number of bytes from the source (for example by seeking forward.)
In case of error, it should flag an appropriate error on the reader.
| typedef struct mpack_reader_t mpack_reader_t |
A buffered MessagePack decoder.
The decoder wraps an existing buffer and, optionally, a fill function. This allows efficiently decoding data from existing memory buffers, files, streams, etc.
All read operations are synchronous; they will block until the requested data is fully read, or an error occurs.
This structure is opaque; its fields should not be accessed outside of MPack.
| typedef void(* mpack_reader_teardown_t) (mpack_reader_t *reader) |
A teardown function to be called when the reader is destroyed.
| void mpack_discard | ( | mpack_reader_t * | reader | ) |
Reads and discards the next object.
This will read and discard all contained data as well if it is a compound type.
| void mpack_done_array | ( | mpack_reader_t * | reader | ) |
Finishes reading an array.
This will track reads to ensure that the correct number of elements are read.
| mpack_done_bin | ( | mpack_reader_t * | reader | ) |
Finishes reading a binary data blob.
This will track reads to ensure that the correct number of bytes are read.
| mpack_done_ext | ( | mpack_reader_t * | reader | ) |
Finishes reading an extended type binary data blob.
This will track reads to ensure that the correct number of bytes are read.
| mpack_done_map | ( | mpack_reader_t * | reader | ) |
Finishes reading a map.
This will track reads to ensure that the correct number of elements are read.
| mpack_done_str | ( | mpack_reader_t * | reader | ) |
Finishes reading a string.
This will track reads to ensure that the correct number of bytes are read.
| void mpack_done_type | ( | mpack_reader_t * | reader, |
| mpack_type_t | type | ||
| ) |
Finishes reading the given type.
This will track reads to ensure that the correct number of elements or bytes are read.
| mpack_tag_t mpack_peek_tag | ( | mpack_reader_t * | reader | ) |
Parses the next MessagePack object header (an MPack tag) without advancing the reader.
If an error occurs, the reader is placed in an error state and a nil tag is returned. If the reader is already in an error state, a nil tag is returned.
| void mpack_print | ( | const char * | data, |
| size_t | len | ||
| ) |
Converts a blob of MessagePack to pseudo-JSON for debugging purposes and pretty-prints it to stdout.
| void mpack_print_file | ( | const char * | data, |
| size_t | len, | ||
| FILE * | file | ||
| ) |
Converts a blob of MessagePack to pseudo-JSON for debugging purposes and pretty-prints it to the given file.
| void mpack_read_bytes | ( | mpack_reader_t * | reader, |
| char * | p, | ||
| size_t | count | ||
| ) |
Reads bytes from a string, binary blob or extension object, copying them into the given buffer.
A str, bin or ext must have been opened by a call to mpack_read_tag() which yielded one of these types, or by a call to an expect function such as mpack_expect_str() or mpack_expect_bin().
If an error occurs, the buffer contents are undefined.
This can be called multiple times for a single str, bin or ext to read the data in chunks. The total data read must add up to the size of the object.
| reader | The MPack reader |
| p | The buffer in which to copy the bytes |
| count | The number of bytes to read |
| char* mpack_read_bytes_alloc | ( | mpack_reader_t * | reader, |
| size_t | count | ||
| ) |
Reads bytes from a string, binary blob or extension object, allocating storage for them and returning the allocated pointer.
The allocated string must be freed with MPACK_FREE() (or simply free() if MPack's allocator hasn't been customized.)
Returns NULL if any error occurs, or if count is zero.
| const char* mpack_read_bytes_inplace | ( | mpack_reader_t * | reader, |
| size_t | count | ||
| ) |
Reads bytes from a string, binary blob or extension object in-place in the buffer.
This can be used to avoid copying the data.
A str, bin or ext must have been opened by a call to mpack_read_tag() which yielded one of these types, or by a call to an expect function such as mpack_expect_str() or mpack_expect_bin().
If the bytes are from a string, the string is not null-terminated! Use mpack_read_cstr() to copy the string into a buffer and add a null-terminator.
The returned pointer is invalidated on the next read, or when the buffer is destroyed.
The reader will move data around in the buffer if needed to ensure that the pointer can always be returned, so this should only be used if count is very small compared to the buffer size. If you need to check whether a small size is reasonable (for example you intend to handle small and large sizes differently), you can call mpack_should_read_bytes_inplace().
This can be called multiple times for a single str, bin or ext to read the data in chunks. The total data read must add up to the size of the object.
NULL is returned if the reader is in an error state.
| mpack_error_too_big | if the requested size is larger than the buffer size |
| void mpack_read_cstr | ( | mpack_reader_t * | reader, |
| char * | buf, | ||
| size_t | buffer_size, | ||
| size_t | byte_count | ||
| ) |
Reads bytes from a string, ensures that the string contains no NUL bytes, copies the bytes into the given buffer and adds a null-terminator.
A string must have been opened by a call to mpack_read_tag() which yielded a string, or by a call to an expect function such as mpack_expect_str().
The given byte count must match the size of the string as returned by the tag or expect function. The string will only be copied if the buffer is large enough to store it.
If an error occurs, the buffer will contain an empty string.
| mpack_error_too_big | if the string plus null-terminator is larger than the given buffer size |
| mpack_error_type | if the string contains a null byte. |
| mpack_tag_t mpack_read_tag | ( | mpack_reader_t * | reader | ) |
Reads a MessagePack object header (an MPack tag.)
If an error occurs, the reader is placed in an error state and a nil tag is returned. If the reader is already in an error state, a nil tag is returned.
If the type is compound (i.e. is a map, array, string, binary or extension type), additional reads are required to get the contained data, and the corresponding done function must be called when done.
| void mpack_read_utf8 | ( | mpack_reader_t * | reader, |
| char * | p, | ||
| size_t | byte_count | ||
| ) |
Reads bytes from a string, ensures that the string is valid UTF-8, and copies the bytes into the given buffer.
A string must have been opened by a call to mpack_read_tag() which yielded a string, or by a call to an expect function such as mpack_expect_str().
The given byte count must match the complete size of the string as returned by the tag or expect function. You must ensure that the buffer fits the data.
This does not accept any UTF-8 variant such as Modified UTF-8, CESU-8 or WTF-8. Only pure UTF-8 is allowed.
If an error occurs, the buffer contents are undefined.
Unlike mpack_read_bytes(), this cannot be used to read the data in chunks (since this might split a character's UTF-8 bytes, and the reader does not keep track of the UTF-8 decoding state between reads.)
| mpack_error_type | if the string contains invalid UTF-8. |
| void mpack_read_utf8_cstr | ( | mpack_reader_t * | reader, |
| char * | buf, | ||
| size_t | buffer_size, | ||
| size_t | byte_count | ||
| ) |
Reads bytes from a string, ensures that the string is valid UTF-8 with no NUL bytes, copies the bytes into the given buffer and adds a null-terminator.
A string must have been opened by a call to mpack_read_tag() which yielded a string, or by a call to an expect function such as mpack_expect_str().
The given byte count must match the size of the string as returned by the tag or expect function. The string will only be copied if the buffer is large enough to store it.
This does not accept any UTF-8 variant such as Modified UTF-8, CESU-8 or WTF-8. Only pure UTF-8 is allowed, but without the NUL character, since it cannot be represented in a null-terminated string.
If an error occurs, the buffer will contain an empty string.
| mpack_error_too_big | if the string plus null-terminator is larger than the given buffer size |
| mpack_error_type | if the string contains invalid UTF-8 or a null byte. |
| const char* mpack_read_utf8_inplace | ( | mpack_reader_t * | reader, |
| size_t | count | ||
| ) |
Reads bytes from a string in-place in the buffer and ensures they are valid UTF-8.
This can be used to avoid copying the data.
A string must have been opened by a call to mpack_read_tag() which yielded a string, or by a call to an expect function such as mpack_expect_str().
The string is not null-terminated! Use mpack_read_utf8_cstr() to copy the string into a buffer and add a null-terminator.
The returned pointer is invalidated on the next read, or when the buffer is destroyed.
The reader will move data around in the buffer if needed to ensure that the pointer can always be returned, so this should only be used if count is very small compared to the buffer size. If you need to check whether a small size is reasonable (for example you intend to handle small and large sizes differently), you can call mpack_should_read_bytes_inplace().
This does not accept any UTF-8 variant such as Modified UTF-8, CESU-8 or WTF-8. Only pure UTF-8 is allowed.
Unlike mpack_read_bytes_inplace(), this cannot be used to read the data in chunks (since this might split a character's UTF-8 bytes, and the reader does not keep track of the UTF-8 decoding state between reads.)
NULL is returned if the reader is in an error state.
| mpack_error_type | if the string contains invalid UTF-8 |
| mpack_error_too_big | if the requested size is larger than the buffer size |
| mpack_error_t mpack_reader_destroy | ( | mpack_reader_t * | reader | ) |
Cleans up the MPack reader, ensuring that all compound elements have been completely read.
Returns the final error state of the reader.
This will assert in tracking mode if the reader is not in an error state and has any incomplete reads. If you want to cancel reading in the middle of a document, you need to flag an error on the reader before destroying it (such as mpack_error_data).
| mpack_error_t mpack_reader_error | ( | mpack_reader_t * | reader | ) |
Queries the error state of the MPack reader.
If a reader is in an error state, you should discard all data since the last time the error flag was checked. The error flag cannot be cleared.
| void mpack_reader_flag_error | ( | mpack_reader_t * | reader, |
| mpack_error_t | error | ||
| ) |
Places the reader in the given error state, calling the error callback if one is set.
This allows you to externally flag errors, for example if you are validating data as you read it.
If the reader is already in an error state, this call is ignored and no error callback is called.
| mpack_error_t mpack_reader_flag_if_error | ( | mpack_reader_t * | reader, |
| mpack_error_t | error | ||
| ) |
Places the reader in the given error state if the given error is not mpack_ok, returning the resulting error state of the reader.
This allows you to externally flag errors, for example if you are validating data as you read it.
If the given error is mpack_ok or if the reader is already in an error state, this call is ignored and the actual error state of the reader is returned.
| void mpack_reader_init | ( | mpack_reader_t * | reader, |
| char * | buffer, | ||
| size_t | size, | ||
| size_t | count | ||
| ) |
Initializes an MPack reader with the given buffer.
The reader does not assume ownership of the buffer, but the buffer must be writeable if a fill function will be used to refill it.
| reader | The MPack reader. |
| buffer | The buffer with which to read MessagePack data. |
| size | The size of the buffer. |
| count | The number of bytes already in the buffer. |
| void mpack_reader_init_data | ( | mpack_reader_t * | reader, |
| const char * | data, | ||
| size_t | count | ||
| ) |
Initializes an MPack reader to parse a pre-loaded contiguous chunk of data.
The reader does not assume ownership of the data.
| reader | The MPack reader. |
| data | The data to parse. |
| count | The number of bytes pointed to by data. |
| void mpack_reader_init_error | ( | mpack_reader_t * | reader, |
| mpack_error_t | error | ||
| ) |
Initializes an MPack reader directly into an error state.
Use this if you are writing a wrapper to mpack_reader_init() which can fail its setup.
| void mpack_reader_init_file | ( | mpack_reader_t * | reader, |
| const char * | filename | ||
| ) |
Initializes an MPack reader that reads from a file.
| size_t mpack_reader_remaining | ( | mpack_reader_t * | reader, |
| const char ** | data | ||
| ) |
Returns bytes left in the reader's buffer.
If you are done reading MessagePack data but there is other interesting data following it, the reader may have buffered too much data. The number of bytes remaining in the buffer and a pointer to the position of those bytes can be queried here.
If you know the length of the MPack chunk beforehand, it's better to instead have your fill function limit the data it reads so that the reader does not have extra data. In this case you can simply check that this returns zero.
Returns 0 if the reader is in an error state.
| reader | The MPack reader from which to query remaining data. |
| data | [out] A pointer to the remaining data, or NULL. |
| void mpack_reader_set_context | ( | mpack_reader_t * | reader, |
| void * | context | ||
| ) |
Sets the custom pointer to pass to the reader callbacks, such as fill or teardown.
| reader | The MPack reader. |
| context | User data to pass to the reader callbacks. |
| void mpack_reader_set_error_handler | ( | mpack_reader_t * | reader, |
| mpack_reader_error_t | error_fn | ||
| ) |
Sets the error function to call when an error is flagged on the reader.
This should normally be used with mpack_reader_set_context() to register a custom pointer to pass to the error function.
See the definition of mpack_reader_error_t for more information about what you can do from an error callback.
| reader | The MPack reader. |
| error_fn | The function to call when an error is flagged on the reader. |
| void mpack_reader_set_fill | ( | mpack_reader_t * | reader, |
| mpack_reader_fill_t | fill | ||
| ) |
Sets the fill function to refill the data buffer when it runs out of data.
If no fill function is used, truncated MessagePack data results in mpack_error_invalid (since the buffer is assumed to contain a complete MessagePack object.)
If a fill function is used, truncated MessagePack data usually results in mpack_error_io (since the fill function fails to get the missing data.)
This should normally be used with mpack_reader_set_context() to register a custom pointer to pass to the fill function.
| reader | The MPack reader. |
| fill | The function to fetch additional data into the buffer. |
| void mpack_reader_set_skip | ( | mpack_reader_t * | reader, |
| mpack_reader_skip_t | skip | ||
| ) |
Sets the skip function to discard bytes from the source stream.
It's not necessary to implement this function. If the stream is not seekable, don't set a skip callback. The reader will fall back to using the fill function instead.
This should normally be used with mpack_reader_set_context() to register a custom pointer to pass to the skip function.
The skip function is ignored in size-optimized builds to reduce code size. Data will be skipped with the fill function when necessary.
| reader | The MPack reader. |
| skip | The function to discard bytes from the source stream. |
| void mpack_reader_set_teardown | ( | mpack_reader_t * | reader, |
| mpack_reader_teardown_t | teardown | ||
| ) |
Sets the teardown function to call when the reader is destroyed.
This should normally be used with mpack_reader_set_context() to register a custom pointer to pass to the teardown function.
| reader | The MPack reader. |
| teardown | The function to call when the reader is destroyed. |
| bool mpack_should_read_bytes_inplace | ( | mpack_reader_t * | reader, |
| size_t | count | ||
| ) |
Returns true if it's a good idea to read the given number of bytes in-place.
If the read will be larger than some small fraction of the buffer size, this will return false to avoid shuffling too much data back and forth in the buffer.
Use this if you're expecting arbitrary size data, and you want to read in-place for the best performance when possible but will fall back to a normal read if the data is too large.
| void mpack_skip_bytes | ( | mpack_reader_t * | reader, |
| size_t | count | ||
| ) |
Skips bytes from the underlying stream.
This is used only to skip the contents of a string, binary blob or extension object.

Influx Inspect disk shard utility
Influx Inspect is a tool designed to view detailed information about on disk shards, as well as export data from a shard to line protocol that can be inserted back into the database.
InfluxDB inch tool
Use the InfluxDB inch tool to test InfluxDB performance. Adjust metrics such as the batch size, tag values, and concurrent write streams to test how ingesting different tag cardinalities and metrics affects performance.
Graphs and dashboards
Use Chronograf or Grafana dashboards to visualize your time series data.
Tip: Use template variables in your dashboards to filter meta query results by a specified period of time (see example below).
Filter meta query results using template variables
The example below shows how to filter hosts retrieving data in the past hour.
Example
# Create a retention policy.
CREATE RETENTION POLICY "lookup" ON "prod" DURATION 1d REPLICATION 1
# Create a continuous query that groups by the tags you want to use in your template variables.
CREATE CONTINUOUS QUERY "lookupquery" ON "prod" BEGIN SELECT mean(value) as value INTO "your.system"."host_info" FROM "cpuload"
WHERE time > now() - 1h GROUP BY time(1h), host, team, status, location END;
# In your Grafana or Chronograf templates, include your tag values.
SHOW TAG VALUES FROM "your.system"."host_info" WITH KEY = “host”
Note: In Chronograf, you can also filter meta query results for a specified time range by creating a
custom meta query
template variable and adding a time range filter.

What's your take on the DBC/EDA experience?
What I see when I look at the DBC/EDA experience, is their way of teaching and growing
the individual, as part of a whole and living, community.
A family outside of it's normal definition, one bound not by blood, but instead by commonly held values and goals.
What are your impressions?
My impressions so far are that my first impressions were right on the money.
Here resides
a school, a home, a place of work and growth,
that I would love nothing more than to be a part of.
How do you see yourself engaging with this type of culture?
I can hardly wait to further immerse myself in what I have seen of the EDA culture.
To give it my all, only to be humbled and then ride the emotions that come from short team defeats.
To reflect, look deeper inside and see the still more, yet untouched gears that we all have and to
learn as a group how to put them into action.
Have your expectations of EDA changed? If so, how?
Trepidation voided, gut instincts confirmed.
Are you excited to participate in this kind of learning environment? Does it make you nervous?
I am really looking forward to more EDA experience, excited to be a part of the Mamaku cohort and my nerves are as of now, resting. I have no doubt that as a whole, we can overcome inconceivable odds.

| const void * | miscParam | |||
| ) |
Create EDMA3 Resource Manager Object.
This API is used to create the EDMA3 Resource Manager Object. It should be called only ONCE for each EDMA3 hardware instance.
Init-time Configuration structure for EDMA3 hardware is provided to pass the SoC specific information. This configuration information could be provided by the user at init-time. In case user doesn't provide it, this information could be taken from the SoC specific configuration file edma3_<SOC_NAME>_cfg.c, in case it is available.
This API clears the error specific registers (EMCR/EMCRh, QEMCR, CCERRCLR) and sets the TCs priorities and Event Queues' watermark levels, if the 'miscParam' argument is NULL. User can avoid these registers' programming (in some specific use cases) by SETTING the 'isSlave' field of 'EDMA3_RM_MiscParam' configuration structure and passing this structure as the third argument (miscParam).
After successful completion of this API, Resource Manager Object's state changes to EDMA3_RM_CREATED from EDMA3_RM_DELETED.
| phyCtrllerInstId | [IN] EDMA3 Controller Instance Id (Hardware instance id, starting from 0). | |
| gblCfgParams | [IN] SoC specific configuration structure for the EDMA3 Hardware. | |
| miscParam | [IN] Misc configuration options provided in the structure 'EDMA3_RM_MiscParam'. For default options, user can pass NULL in this argument. |
| EDMA3_RM_Result EDMA3_RM_delete | ( | uint32_t | phyCtrllerInstId, | |
| const void * | param | |||
| ) |
Delete EDMA3 Resource Manager Object.
This API is used to delete the EDMA3 RM Object. It should be called once for each EDMA3 hardware instance, ONLY after closing all the previously opened EDMA3 RM Instances.
After successful completion of this API, Resource Manager Object's state changes to EDMA3_RM_DELETED.
| phyCtrllerInstId | [IN] EDMA3 Phy Controller Instance Id (Hardware instance id, starting from 0). | |
| param | [IN] For possible future use. |
| EDMA3_RM_Handle EDMA3_RM_open | ( | uint32_t | phyCtrllerInstId, | |

| EDMA3_RM_Result * | errorCode | |||
| ) |
Open EDMA3 Resource Manager Instance.
This API is used to open an EDMA3 Resource Manager Instance. It could be called multiple times, for each possible EDMA3 shadow region. Maximum EDMA3_MAX_RM_INSTANCES instances are allowed for each EDMA3 hardware instance.
Also, only ONE Master Resource Manager Instance is permitted. This master instance (and hence the region to which it belongs) will only receive the EDMA3 interrupts, if enabled.
User could pass the instance specific configuration structure (initParam->rmInstInitConfig) as a part of the 'initParam' structure, during init-time. In case user doesn't provide it, this information could be taken from the SoC specific configuration file edma3_<SOC_NAME>_cfg.c, in case it is available.
By default, this Resource Manager instance will clear the PaRAM Sets while allocating them. To change the default behavior, user should use the IOCTL interface appropriately.
| phyCtrllerInstId | [IN] EDMA3 Controller Instance Id (Hardware instance id, starting from 0). | |
| initParam | [IN] Used to Initialize the Resource Manager Instance (Master or Slave). | |

Close EDMA3 Resource Manager Instance.
This API is used to close a previously opened EDMA3 RM Instance.
| hEdmaResMgr | [IN] Handle to the previously opened Resource Manager Instance. | |
| param | [IN] For possible future use. |

I dug this photo out from my archives. It was taken almost 3 years back, at Auroville near Pondicherry, using my Canon Powershot S3IS.
I like the arrangement of the flowers. Very well done. Its not an easy task I suppose especially since they are floating on water! Technique-wise, the composition is very good. Also, I used the lighting conditions to my advantage. If you notice, the photo was shot with the lens being directly above the center of the vase. Yet, there is not as much as a hint of shadow anywhere. I had to struggle a bit to get this right.
I wish I had adjusted the exposure a bit better, and used vivid tone. Plus, some fiddling with the manual focus might have helped too. Finally, the in the top of the photo, you see that a part of the vase has been clipped off, which messed up the symmetry.


Pick's Theorem
Pick's theorem [Crilly, p. 113][Stewart, p. 125] is a formula for calculating the area of a polygon, which is drawn on a grid. It is remarkably simple:
Here, P is the number of points on the perimeter and I is the number of points on the interior. The theorem was proved by Georg Pick in 1899. It works for any shape which joins discrete points with whole number coordinates, and where the boundary does not cross itself.
So for the following polygon, Area = (15/2) + 4 -1 = 10.5.
It's a great formula for a person to use. You can easily count the points on the perimeter and in the interior. But don't get too excited about it's application in computing; working out which points are on the interior is not a trivial problem for a computer to solve [Sedgewick, p. 353].

Republished from Opperator blog
Behind the Curtain posts explore the development of a piece of Opperator's architecture, including the what, why, and how.
Grape is a Ruby framework for building restful APIs on the web. We're using it extensively to build Opperator. Out of the box, Grape has built-in support for versioning your APIs. There's general information about how to use versioning in the Grape README and the wiki, but this post is more about digging into the nitty-gritty and discussing some of the design decisions and implementation details that've been merged in recently.
Previously, Grape supported API versioning by prefixing the version name in the url. For example:
class MyAPI < Grape::API
version :v1
# GET /v1/cows
get '/cows' do
# retrieve bovine goodness
end
end
When version
is called, the version names are passed into
Grape::Middleware::Versioner
pre-refactored
file
When a request comes in, the middleware looks for a matching version in the
path. If it finds the version, it rewrites the path info without the version
prefix, sets env[api.version]
, and moves along it's merry way. If no version
is matched, then a 404 is thrown.
This works as you'd expect, but introduces your versioning scheme into your resource uri's. Workable, but it messes up those pretty restful uris. Fortunately, the HTTP protocol Accept header is a perfect fit for this problem. RFC 2616 defines the Accept header as:
The Accept request-header field can be used to specify certain media types which are acceptable for the response. Accept headers can be used to indicate that the request is specifically limited to a small set of desired types, as in the case of a request for an in-line image.
While the example the RFC gives is related to multimedia, if you squint and replace the references to media with 'version', then you have a good overview of header based API versioning. This Accept header field can be used to scope a request to a specific API version. For example, the Github API understands the following Accept header:
Accept: application/vnd.github-v1+json
The client who sent this header is asking the server "Hey Github, can you give me a responses that is version v1 and formatted in JSON?". When Github sees this request, it can do one of two things. If it's able to answer the question, then it processes the request as normal. However, if Github doesn't understand the Accept field value, then it should send a 406 Not Acceptable response.
Revisiting our code sample, we would define our API as follows:
class MyAPI < Grape::API
version :v1, :using => :header, :vendor => 'intridea', :format => :json
# GET /cows
get '/cows' do
# retrieve bovine goodness
end
end
Header based versioning is the new default versioning strategy, but I
explicitly specified it in the example for clarity. The vendor
option is new
and is a way to describe the vendor providing this API, and the format
option is the expected response format. Similar to path based versioning,
Grape::Middleware
is responsible for figuring out the version being
requested and setting env[api.version]
. But since there are now multiple
strategies for handling versions, Grape::Middleware::Versioner
has been
split into two middlewares. Grape::Middleware::Versioner::Path
is the
original path based middleware, and Grape::Middleware::Versioner::Header
is
the new kid on the block. Relevant commit
here
This new middleware will use the following format in the Accept header when matching for versions:
application/vnd.:vendor-:version+:format
These are the fields that are original declared when version
was first
called. If the middleware is able to match these fields, then the endpoint is
called with some extra environment variables 'api.vendor', 'api.version', and
'api.format'. If the version couldn't be matched, then the middleware returns
404 and also sets the X-CASCADE header to pass. That last part is
important because it allows Rack::Mount
to keep looking for other endpoints which might match the version.
You can also control the routing behavior when no Accept header is specified
with the strict
option. If strict
is set to true, then a 404 will be
returned when no Accept is set. If strict
is false, then the first matched
endpoint is returned. This is inline with the RFC definition and basically
means that the client doesn't care which version the server responds with.
Most likely, if strict
is set to false, you'd like to use the latest
available version. To achieve this, you should mount your latest version as
high as possible (similar to routes precedence in Rails)
class MyAPI < Grape::API
# version v2 has higher precedence than v1
version :v2, :strict => false do
get '/cows' do
end
end
version :v1 do
get '/cows' do
end
end
end
Currently, path and header based versioning are what's understood, but we've opened up the possibility of custom versioning strategies. Prefer to do domain based versioning? Or IP-based versioning? If you want to get really wacky, you can even version based on the lunar calendar.
Extra thanks goes out to jwkoelewijn for creating the initial feature branch and kicking off the discussion.


I've included peerJS in my project kreator.js and now you can use your mobile phone to control the slides without any server involvement (bonus points). The setup is fairly easy and it works on most modern devices.
PeerJS takes advantage of the latest WebRTC features to implement peer to peer communication entirely client side. This means that you can have complete web applications that talk to each other and exchange data without a backend.
Another advantage is the fact that communication speed is limited only by the speed of the peers. Not having a 3rd party server means no latency overhead.
DataChannel API is part of webRTC that enables real time communication in the browser without any plugins. WebRTC is comprised of MediaStream, RTCPeerConnection and RTCDataChannel.
MediaStream (aka getUserMedia) page on MDN Supported by and Blackberry 10.
Gives you access to the user webcam and microphone. Support (behind appropriate prefix) in all browsers except Safari and Internet Explorer.
RTCPeerConnection page on MDN Supported by
Handles efficient streaming of data between two peers
RTCDataChannel page on HTML5rocks Not sure about support
Allows for data transfer directly from one peer to another.
PeerJS is a wrapper of the browser implementation of WebRTC. It offers abstraction for easy-to-use peer-to-peer connections.
The first thing you need to do is instanciate a new Peer object. This will provide you with methods to connect to other users or receive connections yourself.
var peer = new Peer({key: 'myapikey'});
You need to register with peerJS in order to receive an API key, but don't worry it's all free. They also offer a CDN network to serve the library or you could host it yourself.
Find out your ID
peer.on('open', function(id) {
console.log('My peer ID is: ' + id);
});
Sending a message to another peer.
var conn = peer.connect('another-peers-id'); // who to connect to
conn.on('open', function(){ // when the connection is ready
// send a string
conn.send('hi!');
// or a JSON object
conn.send({
username: 'andrei',
message: 'hello'
});
});
You can send strings, JSON, blobs or ArrayBuffers.
Listening for incoming connections
peer.on('connection', function(conn) {
// this event is triggered when a connection
// has been established with a remote peer
// we can use the `conn` object to listen for data events
conn.on('open', function() {
conn.on('data', function(data) {
// data contains the received message
console.log(data);
});
// we can also send back messages to the peer
conn.send('Hi!');
});
});
Gist and working example
Also checkout out kreator.js for a real world use case.
Sometimes you can't connect to the other peer due to network configuration (read more) in which case you need to use a TURN server
The library also provides a set of utility methods that provide you with information about the browser support.
// if browser supports media stream and peer connection
util.supports.audioVideo // true or false

HashBounds - Demo
Hashbounds allow you to optimise collision detection. It is hightly efficient and is hierarchical. This means it is more efficient than a Quadtree or a regular spatial hash.

To make the develoment as natural as possible for a frontend developer, the views are typically written as plain XHTML files. The XHTML views are treated as XML files with elements from http://www.w3.org/1999/xhtml
namespace. When requested, the view is transformed using it's corresponding XSLT stylesheet. The result of that transformation is sent to the response; that's typically the HTML that the user agent receives.
The complete process is actually more complicated than that, the document transform flow section provides more in-depth information about additional background processing steps performed by Sage.
