Hartford Hospital has recently discovered an original "Mrs. Chase"… (STEPHEN DUNN, Hartford…)
Long before there was "Annie," the iconic doll used for CPR-training classes, there was "Mrs. Chase."
Created in 1911, the lifesize Mrs. Chase doll is the first known doll to have been designed specifically for training health care workers. The original was built in Rhode Island for Hartford Hospital, which — to the surprise of just about everyone at the hospital — still has it.
A few weeks ago Steven Donahue, director of the hospital's Center for Education, Simulation and Innovation, was putting together a brochure about the hospital's training mannequins. A Google search he did revealed that simulation mannequins began with the Mrs. Chase doll and that Hartford Hospital had the very first.
It was the first that Donahue ever had heard of Mrs. Chase, and he doubted the doll was still in the hospital after 101 years.
"I figured, no way could we still have it around," he said, but he mentioned it to Steven Lytle, the hospital's archivist. Lytle confirmed that there was a Mrs. Chase in the hospital's archives and retrieved it, which was wearing an original, hand-stitched Hartford Hospital gown.
Aside from a few paint chips, the mannequin is surprisingly well-preserved. It will be part of an exhibit at the hospital on the history of medical training mannequins. Rebecca Stewart, spokeswoman for the hospital, said the exhibit is tentatively scheduled for May.
The mannequin was created by Martha Jenks Chase, of Pawtucket, R.I., who went into business making dolls as children's toys in 1901. Her dolls were popular because they were lightweight and sturdy but still had some of the realistic features of porcelain dolls sold in stores. Within a few years, Chase's dolls were advertised nationally and sold at Macy's and FAO Schwartz.
At the request of A. Lauder Sutherland, principal of the Hartford Hospital Training School, Chase made an adult-sized mannequin for nurse training in 1911. Sutherland, who had gotten tired of the makeshift, straw-filled dummies her nurses had been using, was impressed by Chase's lightweight and durable dolls.
Chase jokingly named the doll Miss Demon Strator, but eventually the handful of training dolls she made became known as "Mrs. Chase." In 1914, Chase created "Arabella," an upgraded version that allowed nurses to practice arm injections. Chase died in 1925, but the M.J. Chase Co. continued in business until 1981.
Most of what is known about the origins of Mrs. Chase is from the research of Eleanor Krohn Herrmann, a professor emeritus of nursing at UConn. She started researching the doll about 15 years ago after she happened to mention Mrs. Chase to a nursing student.
"She looked at me like I had four foreheads," said Herrmann, who lives in Wallingford. Although the Mrs. Chase doll was once ubiquitous in nurses' training classes, Herrmann said very little was known about the doll or her creator.
"So I wanted to know where this Mrs. Chase came from, and began looking," she said.
Mrs. Chase was used to train nurses how to dress a patient, turn her over and transfer her from bed to bed. Outfitted with movable joints at the hips, arms and legs, the dolls were designed with some help from Chase's husband, who was a doctor.
Next to today's simulation medical dolls, Mrs. Chase is decidedly low-tech. You can't give her CPR or injections. Compare that to SimMan 3G, better known to Hartford Hospital staff as "Tommy," who can sweat, bleed and have seizures. In the next room is "Jennifer," another state-of-the-art mannequin who "delivers" a simulation of a newborn baby. The robotic mother-to-be even screams to make the scenario more realistic. Donahue said the next-generation software might include cursing as well, "although we're trying to be sensitive about it."
These medical training mannequins all were made by Laerdal, a Norwegian company, which has dominated the market for decades. Jon Laerdal, a strategic marketing manager for the company, got a chance to see the Mrs. Chase doll when he visited Hartford Hospital last month to present some new software. As amedical mannequin cognoscente, Laerdal long had known of Mrs. Chase but had never seen one of the dolls.
"It was unbelievable how good look she looked for a 100-year-old doll," he said.
The Laerdal company began in the 1940s, with the creation of Resusci Annie, now the well-known CPR doll. Legend within the small community of CPR historians has it that Annie's likeness was based on the death mask of a young woman from Paris who drowned herself in the Seine River after a love affair went sour.
"My grandfather, the founder of the company, saw the death mask hanging on the wall of his parents-in-law when he was searching for the face of Resusci Annie," Laerdal said. "Now she's referred to as the mannequin that went from the mask of tragedy to the kiss of life."

Ryerson Station State Park is a 1,164-acre (471 ha) Pennsylvania state park in Richhill Township, Greene County, Pennsylvania in the United States. It was previously home to Ronald J. Duke Lake, a 52-acre (21 ha) artificial lake on the North Fork of the Dunkard Fork of Wheeling Creek, that was constructed in 1960, but drained in 2005 due to structural concerns about the dam. Ryerson Station State Park is 3 miles (5 km) from Wind Ridge just off Pennsylvania Route 21 very close to the West Virginia state line.
The park is named for Fort Ryerson. This fort was constructed by the Commonwealth of Virginia in 1792 as a refuge from the raids of the local Native Americans who were resisting the settlement of the Ohio River Valley by the United States. Ownership of the land in this part of Pennsylvania was disputed among several parties including Virginia, Pennsylvania and the Native Americans.The state acquired the land in 1958. Duke Lake was completed with the construction of a dam in 1960 and finally the park was opened in 1967.

One of the most popular board/tabletop games you can buy is Carcassonne. In Carcassonne the player places down tiles to create cities, roads and farmland; then places one of their own pieces/meeples to score points. It's a pretty simple idea which in turn creates some tactical gameplay methods as the player's try to score the most points. I like Carcassonne, but not as much as I love Taluva.
Taluva is very similar to Carcassonne in that it involves tile and piece placement, but it is different in several key aspects. In Taluva the player is not building castles, roads, or farmland; but is instead building an island. The pieces called volcano tiles are three-pointed star shapes, each one having three types of land on it. Some have more than one of the same kind, others have three different land types. The only thing that is common about the tiles (other than their shapes) is that each one has a volcano on them. These volcano places cannot have pieces placed on them, but do cause volcanic eruptions which means that the tiles can be placed on top of each other, turning the land from 2D into 3D, thus creating hills which can then turn into mountains.
Upon placing tiles, players can then place their pieces onto their tiles. Players have 3 different types of pieces:
To begin with, players can only build huts. These can be placed onto a tile they have just placed, or alternatively, players can expand their already built settlements by adding more huts. The benefit of this is so that they can build Temples which require a settlement branching across three areas of land. At the end of the game, whoever has built the most temples wins. There is though another side to this, as to build more temples, the player will need to create separate settlements, as there can only be one temple in each settlement. One benefit to building the temple though is that it can prevent volcanic eruptions.
When a volcanic eruption is caused by a player, they can use it as a way of destroying another players settlement. So when they place a tile, it can wipe out huts. Volcanic eruptions though do have rules to follow:
- They can't wipe out an entire settlement. If placing a tile would cause this; the player wouldn't be allowed to do that move. At least one space of a settlement must survive.
- Eruptions cannot destroy Temples or Towers.
Placing Temples or Towers can therefore be a great way of preventing large-scale damage to player's settlements as it would prevent other players from using volcanic eruptions. Therefore, opposing players would need to consider using eruptions in locations where players may be on the verge of placing a Temple or Tower.
For a player to place a Tower, they need to place it next to a settlement of any size, doesn't need to follow the same rules as Temples. Towers though do need to be placed on a level 3 tile; so it can take time to build them as the land may need plenty of eruptions to allow a third level of tile placement. Once this is done however, a Tower can then be placed next to a settlement, even if there is a mega cliff from the tower down to the next hut.
Once all the tiles have been placed, it comes down to the player who has placed the most Temples. Whoever has achieved this is the winner; if there is a tie however, it comes down to who has placed the most Towers. If there is still a tie for first after that, then the player who has placed the most huts wins. There is though another way to win; because if one player has placed all of two of their pieces:
- All Huts and all Temples
- All Temples and all Towers
- All Towers and all Huts
Then that player wins the game automatically; even if there are still tiles to be placed.
Taluva is a very easy game just to pick up and play, and is not all that long either. It can be tactical, be played both offensively and defensively and it can be fun just to destroy another players civilization with the simple act of causing a volcanic eruption. It's beautifully designed and crafted, and it's fun just to watch how the land starts off flat before becoming very hilly and mountainous. Altogether; Taluva is a very fun game and also one of my favourite Board Games.

The Python module datetime allows you to calculate the days between two given dates with relative ease. I am using the US date format month/day/year, but you can change that by giving attention to the order of the extracted tuple.
# find the days between 2 given dates
# tested with Python25 HAB
import datetime as dt
# US format month/day/year
dateStr1 = '7/14/2006'
dateStr2 = '5/1/2007'
m1, d1, y1 = (int(x) for x in dateStr1.split('/'))
m2, d2, y2 = (int(x) for x in dateStr2.split('/'))
date1 = dt.date(y1, m1, d1)
date2 = dt.date(y2, m2, d2)
dateDiff = date2 - date1
print 'Difference in days = %d' % dateDiff.days # 291

Achieving the optimum balance for a life lived well
Ever wondered what balance of exercise, sleep, food and work delivers the best outcomes for your physical and mental health?
A team of scientists led by researchers in South Australia is embarking on a four-year study to find out.
The international team will use 200,000 data sources from Fitbits, activity monitors and time-use surveys linked with health data to create a prototype.
University of South Australia lead researcher Dr Dot Dumuid said first-class prototype would provide personalised advice on how best to use a 24-hour period for specific health outcomes.
She said Israeli mathematicians, University of Adelaide computer scientists as well as global behavioural epidemiologists and public health specialists would develop an analytical method to work out the ideal length of time needed on activities in order to achieve particular outcomes.
The software will form the basis of an online tool allowing people to improve time management while achieving the optimal health for their lifestyle.
"Every day everybody is given 24 hours. How people allocate that time to activities impacts their health," Dr Dumuid said. "We already know that things like screen time, exercise, sleep and work-life balance influence health, but now we are thinking about these things as linked parts that together make up a complete day. So, rather than talking about activities in isolation, we talk about 'healthy days' or 'the optimal mix of activities'."
The project was this month awarded a $951,708 grant from Australia's National Health and Medical Research Council to collate data, create and test optimisation methods and develop a prototype.
"We already have access to many such data sets, and we are reaching out to studies across the world to gain access to their data also," Dr Dumuid said.
"But because people measure time in lots of different ways and there are different brands and different parameters that people have used in their studies, we will have to do some calibration across the different studies to make sure they can be put together.
"In industry optimisation, this kind of data happens all the time. For example, people optimise the mix of fertilizer to get the best crop yields but then there are also other factors like the lowest cost."


" or just info, but many timeouts might be "wake up", how do you encode that logic somewhere?
There is no equivalent of this in a trace, so there's one less thing to worry about.
Messages
Something like found ${count} users in the cache looks like a good log message. It is clear and has the information you care about. However, when you come to querying your log aggregation system, you need to do a free-text search on a substring of the message or use a wildcard search. Both of these operations are slow, and worse still cannot help you with the negative version of the question "find me operations where the cache wasn't checked".
Assuming structured logs are being used, we can at least add the count as a property to the log message so it can now be filtered on by the log aggregator. At which point, why do you need the log message at all? Why not just have log({ users_in_cache: count })?
The logging libraries also put more importance on the message than the properties by having it be the first (and only required) argument to the logging function. From a querying and analysis perspective, this is wrong: messages force you into free text searching and reduce the likelihood of fast queries on attributes.
Given this logline:
logger.info("found the user in the cache", userId);
You could reconstruct this as a statement that can be filtered on:
span.addAttributes({
 user_in_cache: true,
 user_id: userId,
})
Mixed Outputs / Semantics
Nowadays, people configure their HTTP server to write logs to stdout rather than to a log file. This makes a great deal of sense, as now a separate piece of software can tail the logs and send them off to the aggregator. Your application's output, however, will likely end up with mixed plaintext and structured logs, mostly down to libraries and frameworks doing their own thing with logging, which is probably not the same as what you are doing (or other libraries are doing.)
The second problem with writing logs to stdout is that it mixes the semantics of log lines with console output. While both log messages and console output are (probably) just text, they do have different purposes. A piece of feedback might be "Server listening on port 3000. Click here to open the browser". This is useful to a local user running the app but isn't valuable in your logs. Not to mention, its plaintext output on the console, rather than structured, so now your log tailer needs to figure out what to do with it.
With OpenTelemetry, you instead configure an exporter to handle all your traces (and logs and metrics, if you desire.) This is typically sent as OTLP format either directly to a vendor or to an OTEL Collector instance, which can add/remove/modify data and send it to one or multiple places.
Now you are free to write whatever feedback you want to stdout.
Relationships
Loglines don't have a causal relationships. At best, structured logs might have some kind of request identifier (such as requestID or correlationID) for all lines written during a request. This allows you to find all the log lines for a given ID, but the log lines themselves don't have a fixed order. Ordering in structured logging relies on the timestamp field, but this is limited to the accuracy and resolution of the time source. It means that it is possible to get lines appearing at the same time when they happened at different times.
Traces come with automatic parent-child relationships, allowing us to see not only all spans in a single request, but what caused each span, and (as we'll get to in the next point) when they happened.
Tracing also takes these relationships another step further but having a standard set of formats to pass trace and span IDs along to other services, embedded in HTTP headers, message queue metadata, or other locations. Assuming all your other services send their traces to the same system, you can start to visualise who calls your service and what the effects are of you calling other services.
Imagine opening a trace from your service and discovering another team in a downstream service has started tracing their stuff, and you suddenly can see even more information about the request. You didn't even do anything! You notice that the way your service is structured causes a lot of load on the downstream, and start a conversation to see if there is a way to make it faster/better.
Timings
The only timing data you get on log lines automatically is the timestamp of when the log line was written. When you want to see how long an operation took, you must start a timer, and then stop the timer, and log the elapsed duration yourself. As this is a manual process, it is often not done, and when it is done, it tends to have inconsistencies across the application, namely timing source (and thus resolution), property name, and format. Is it elapsed, elapsed_ms, duration, or length? does it contain a number of seconds, milliseconds, nanoseconds, or a timestamp format?
By comparison, traces come with startTime, finishTime, and duration attributes, which are not only guaranteed to be there but are set from the same timing source and are always written in the same format.
Combine this with the relationship attributes, and you can now render timing graphs, allowing for easy visualisation of how long each part of a process takes, what can be parallelised, and what parts depend on other parts.
For example, this is a graph showing how long a CI job took to run, showing all the different steps, their durations, and child steps:
a graph of a single build showing each task as a horizontal box denoting start and durations
Querying
Querying can have wildly different performance characteristics depending on which log aggregation service you are using. What unifies all these systems is their slowness, which is mostly down to vast amounts of data which needs indexing so that it can be free text searched. Filtering logs by their structured properties is however pretty quick (usually.)
Where querying falls down is trying to find trends in data, and trying to find answers to negative queries. For example, how would you search for "all requests to x endpoint, where users were not found in the cache"? This requires you to group the logs by request ID, then find an entry with a particular url path, then see if it is missing a log line. The same query in a tracing system would be where path = "/some/api" && !user_in_cache, as the tracing system is already aware of all the spans in a trace, and does the grouping automagically.
Finally, visualising missing data is hard. Take this small example; it is 4 parallel requests to a system, and one of them is missing a log line. Which line is missing?
Timestamp UserID Message
12:51:27 3fcce385be9e fetched 3rd party preferences
12:51:27 3fcce385be9e found user in cache
12:51:27 915d273db25c fetched 3rd party preferences
12:51:27 3fcce385be9e saved successfully
12:51:27 8507d369d11c fetched 3rd party preferences
12:51:27 c4e71b4a29f2 fetched 3rd party preferences
12:51:27 915d273db25c saved successfully
12:51:27 c4e71b4a29f2 found user in cache
12:51:27 c4e71b4a29f2 saved successfully
12:51:27 8507d369d11c found user in cache
12:51:27 8507d369d11c saved successfully
Is it easier to see the one that is different now?
Timestamp UserID Fetched In Cache Saved
12:51:27 3fcce385be9e true true true
12:51:27 915d273db25c true false true
12:51:27 8507d369d11c true true true
12:51:27 c4e71b4a29f2 true true true
Not only is it easy to see at a glance that 915d273db25c didn't find the user in the cache, but also how much less space this takes up (both visually and in terms of storage.)
We can also then use this to query further: show me all traces where in_cache != true, and see what's different about them.
Evolving logs
So, with all that being said, let's look at a practical example of how to go about tracing an existing system and what that looks like.
Ripping all the log statements in an application in one go is not a feasible strategy, especially on a large codebase. However, we can use logs as a decent starting place and evolve our system to something better. Namely, to OpenTelemetry Tracing.
We'll start off with a real pair of functions from one of the codebases I work on. Lots of information changed to protect the guilty innocent. This is run as part of an api call to publish a container, but this part has no web specific code.
func PrepareContainer(ctx context.Context, container ContainerContext, locales []

If we fix a locally profinite group $G$, we note $R(G)$ the category of smooth representations of $G$, $\mathcal{E}$ the set of equivalence classes of $R(G)$, and finaly $Irr(G)$ the set of irreducible equivalence calasses. I recall that the theorem of Cantor-Bernstein says : If $E$ and $F$ two sets. If there is an injection from $E$ to $F$ and an injection from $F$ to $E$, then there is a bijection between $E$ and $F$. This enables us to define an ordering relation in the set of equipotence classes of sets : If $E$ and $F$ two sets, we note $E\leq F$ if $E$ injects in $F$.
Similarly, we define a relation $\leq$ in $\mathcal{E}$, but in general is not an ordering relation, I think that is an ordering relation if $R(G)$ is semisimple (for example, for compact locally profinite group).
If $L$ a non empty subset of $Irr(G)$, we define a $L$-minimal representation as a smooth representation $\pi$ of $G$ such that :
1) For every $\sigma\in L$, $\sigma \leq \pi$.
2) For every $\tau \in R(G)$, if $\sigma\leq\tau$ for every $\sigma\in L$, then $\pi\leq\tau$.
I ask the following questions:
Q1) An $L$-minimal representation exits?
Q2) unicity?
Q3) If $\pi$ an $L$-minimal (if there exist) representation, $dim\mathbf{Hom}_{G}(\sigma,\pi)$, where $\sigma\in L$, is minimal?
I'm interested of this question for the set $L_{k}$ of equivalence classes of irreducible supercuspidal representation of $PGL(n,F)$ with conductor=$k$.
share|improve this question
I am not sure what $L_k$ is. So can you please give a definition. I would expect this to be a finite set, so why can you not take $\pi$ as the direct sum of $\sigma$'s? – Marc Palm Feb 27 '12 at 15:36
I mean $L_k$ is finite, since I guess you induce $GL(n, o / \p^k)$ reps there or something similar, which has only finitely many isos of reps anyway. – Marc Palm Feb 27 '12 at 15:39
How do you define your relation $\leq$? – Joël Feb 27 '12 at 18:36
I defined the set $L_{k}$ as follows : If $\pi$ is a generic irreducible representation of $GL(n,F)$, the theorem of Jaquet & Piateski-Chapiro & Shalika says : there is a positive integer $k$ such that the representation $\pi$ admits a non zero vector fixed by the compact open subgroup $\Gamma_{k}$ defined by : – Rajkarov Feb 28 '12 at 4:50
$$\Gamma_{k}=\left(\begin{array}{cccc|c} \mathcal{O}_{F}^{\times}&\mathcal{O}_{F}&\cdots&\mathcal{O}_{F}&\mathcal{O}_{F}{}\\ \mathcal{O}_{F}&\ddots&\ddots&\vdots&\vdots\\ \vdots&{}&\ddots&\mathcal{O}_{F}&\vdots{}\\ \mathcal{O}_{F}&\cdots&\mathcal{O}_{F}&\mathcal{O}_{F}^{\times}&\mathcal{O}_{F}{}\\ \hline \mathcal{P}_{F}^{k}& \cdots & \cdots &\mathcal{P}_{F}^{k}&\mathcal{O}_{F}^{\times}\\ \end{array}\right)$$ – Rajkarov Feb 28 '12 at 4:53

Here are some observations, too long for a comment:
1) Note that cuspidal irreducible representation are compactly induced
$\sigma = c-ind_K^G \tau = Ind_K^G \tau$
2) You have the second adjointness theorem (proposition on pg. 20 Bushnell-Henniart "Local Langlands for GL(2)".)
$Hom_G( c-ind_K^G \tau, \pi) = Hom_K( \tau, Res_K \pi)$
3) Silberger PGL(2) over the $p$ adics assect that $Res_K \pi$ is essentially $Ind_{B(o)}^{GL(2, o)} 1$ except for a finite dimensional part. I expect this to be true for $GL(n)$.
Hence classify the $\tau$ needed for $L_k$ ( I am not sure what your definition is here). $Res_K \pi$ has been described for cuspidal $\pi$ (Bushnell-Kutzko).
In fact, I think that the supercuspidal representation form a semisimple category, so there the question might really reduce to something trivial, very much like for profinite groups. (profinite groups are actually exactly the compact locally profinite groups;)
share|improve this answer
Your group has compact center (in fact trivial center). So supercuspidal representation indeed form a semi-simple category, as pm said (see _URL_ pg. 22-25, 36).
Your Set $L_k$ is finite set of irreducible representations. So the representation that you are looking for is the direct sum of all the representations in $L_k$
share|improve this answer
More precisely, this comes from the fact that (since the center is compact) supercuspidal representations are projective and injective objects of the category of smooth representations. – Paul Broussous Feb 28 '12 at 7:55

Rodrigues' rotation formula
This article is about the Rodrigues' rotation formula, which is distinct from the related Euler–Rodrigues parameters and The Euler–Rodrigues formula for 3D rotation.
In the theory of three-dimensional rotation, Rodrigues' rotation formula, named after Olinde Rodrigues, is an efficient algorithm for rotating a vector in space, given an axis and angle of rotation. By extension, this can be used to transform all three basis vectors to compute a rotation matrix in SO(3), the group of all rotation matrices, from an axis–angle representation. In other words, the Rodrigues' formula provides an algorithm to compute the exponential map from so(3), the Lie algebra of SO(3), to SO(3) without actually computing the full matrix exponential.
Statement
If v is a vector in 3 and k is a unit vector describing an axis of rotation about which v rotates by an angle θ according to the right hand rule, the Rodrigues formula is
An alternative statement is to write the axis vector as a cross product a × b of any two nonzero vectors a and b which define the plane of rotation, and the sense of the angle θ is measured away from a and towards b. Letting α denote the angle between these vectors, the two angles θ and α are not necessarily equal, but they are measured in the same sense. Then the unit axis vector can be written
This form may be more useful when two vectors defining a plane are involved. An example in physics is the Thomas precession which includes the rotation given by Rodrigues' formula, in terms of two non-collinear boost velocities, and the axis of rotation is perpendicular to their plane.
Derivation
Rodrigues' rotation formula rotates v by an angle θ around vector k by decomposing it into its components parallel and perpendicular to k, and rotating only the perpendicular component.
Vector geometry of Rodrigues' rotation formula, as well as the decomposition into parallel and perpendicular components.
Let k be a unit vector defining a rotation axis, and let v be any vector to rotate about k by angle θ anticlockwise.
Using the dot and cross products, the vector v can be decomposed into components parallel and perpendicular to the axis k,
where the component parallel to k is
called the vector projection of v on k, and the component perpendicular to k is
called the vector rejection of v from k.
The vector k×v can be viewed as a copy of v rotated anticlockwise by 90° about k, so their magnitudes are equal but directions are perpendicular. Likewise the vector k×(k×v) a copy of v rotated anticlockwise through 180° about k, so that k×(k×v) and v are equal in magnitude but in opposite directions (i.e. they are negatives of each other, hence the minus sign). Expanding the vector triple product establishes the connection between the parallel and perpendicular components, for reference the formula is a×(b×c) = (a·c)b − (a·b)c given any three vectors a, b, c.
The component parallel to the axis will not change magnitude nor direction under the rotation,
only the perpendicular component will change direction but retain its magnitude, according to
and since k and v are parallel, their cross product is zero k×v = 0, so that
and it follows
This rotation is correct since the vectors v and k×v have the same length, and k×v is v rotated anticlockwise through 90° about k. An appropriate scaling of v and k×v using the trigonometric functions sine and cosine gives the rotated perpendicular component. The form of the rotated component is similar to the radial vector in 2d plane polar coordinates r, θ in the Cartesian basis
where ex, ey are unit vectors in their indicated directions.
Now the full rotated vector is
so eliminating the parallel component gives
while the elimination of the perpendicular component gives
The factors (1 − cosθ) and sinθ can be seen geometrically in the diagram above.
Matrix notation
Representing v and k×v as column matrices, the cross product can be expressed as a matrix product
Letting K denote the "cross-product matrix" for the vector k,
the matrix equation is, symbolically,
for any vector v. (In fact, K is the unique matrix with this property. It has eigenvalues 0 and ±i).
Iterating the cross product on the right is equivalent to multiplying by the cross product matrix on the left, in particular
The previous rotation formula in matrix language is therefore
and factorizing the v allows the compact expression
where
is the rotation matrix through an angle θ anticlockwise about the axis k, and I the 3×3 identity matrix. This matrix R is an element of the rotation group SO(3) of 3, and K is an element of the Lie algebra so(3) generating that Lie group (note that K is skew-symmetric, which characterizes so(3)). In terms of the matrix exponential,
To see that the last identity holds, one notes that
characteristic of a one-parameter subgroup, i.e. exponential, and that the formulas match for infinitesimal θ.
For an alternative derivation based on this exponential relationship, see Axis–angle representation#Exponential map from so(3) to SO(3). For the inverse mapping, see Axis–angle representation#Log map from SO(3) to so(3).

Traditional Welsh foods
What are the traditional foods of Wales?
Unlike England where a number of culinary traditions filtered down from the upper levels of society, the traditional dishes of Wales literally grew from the land.
Reports from 1896 show that farmers and tenants survived on home-cured meat of domestic animals, home grown vegetables, dairy products and cereal-based dishes. Farmers and cottagers would fatten and slaughter at least one pig a year to provide a constant supply of salted bacon. On larger farms, a bullock or cow was killed and the meat shared between neighbouring farms.
Meat and Vegetables
Cattle provided milk to produce butter and cheese, and vegetables such as leeks, carrots, cabbages, herbs and, from the 18th century onwards, potatoes were grown. Wild fruits, plants, animals and birds were used when in season. Communities living close to coastal regions were able to vary their diet by collecting shellfish and seaweed to make laverbread.
The harsh landscape meant that oats and barley were the most common cereal crops, with wheat confined to the fertile lowlands. Oatmeal was one of the basic elements in the diet of the Welsh. Among the everyday foods served in most rural districts until the early 20th century were Llymru (flummery) and sucan (sowans), consisting of oatmeal steeped in cold water and buttermilk, boiled until thickened and served cool with milk or treacle, bwdram (thin flummery), uwd (porridge) and griwel blawd ceirch (oatmeal gruel).
Oat-bread was the most common bread to be eaten in Wales until the late 19th century. It was used in north Wales as a basic ingredient in cereal pottages such as picws mali (shot) or siot (shot); a popular light meal consisting of crushed oat-bread soaked in buttermilk. Br?es (brose) was a common dish in the agricultural areas of the north and was regularly prepared as a breakfast dish for the men-servants. It was made from crushed oat-bread steeped in meat stock and sprinkled with crushed oat-bread before serving.
Welsh rural society was largely self-supporting with the exception of sugar, salt, tea, rice and currants, which had to be purchased. Very little fresh fruit was bought and eggs were only eaten on very rare occasions.
The open hearth
The open fire was central to cooking throughout the 18th and 19th centuries, and in many rural homes well into the 20th century. Such limited cooking facilities also governed what could be prepared. Stews, joints of meat and puddings were boiled in a cooking pot or cauldron.
Pot ovens were used for roasting meat and baking cakes. Bakestones were widely used to bake oatcakes, drop scones, soda bread, pancakes and griddlecakes (such as Welsh Cakes).
Although the tradition of living off the land survived until a later period in the rural areas, change came with improved roads and modern shopping facilities, not to mention the arrival of fridges and home freezers. Today, the majority of these dishes are mostly eaten on special occasions as 'traditional food'.

A small tinplate screen, found in the industrial communities of both north and south Wales. Small pieces of meat were suspended from the hooks inside the curved, reflecting hood and the whole oven would sit on a trivet (an iron bracket) in front of the fire. It was also possible to bake tea-time favourites such as round cakes, or teisen lap in the shallow drip-tray.

For National Coffee Day Dunkin' Donuts and CareerBuilder have gotten together to survey professionals regarding their coffee consumption. The survey was conducted from August 13 to September 6, 2012 and included more than 4,100 workers nationwide.
The survey found that food preparers and service workers are the people who need coffee the most. Second in need are scientists and sales representatives followed by Marketing/Public Relations Professionals Nurses (Nurse, Nurse Practitioner or Physician Assistant), Editors/Writers/Media Workers, Business Executives,Teachers/Instructors (K-12), Engineering Technicians/Support and finally IT Managers/Network Administrators.
"There's a reason why coffee is a staple in the workplace. Workers report that coffee fuels higher energy and productivity, and serves as a means to socialize with colleagues." said Cynthia McIntyre, Vice President of Marketing & Communications at CareerBuilder
The survey also reviled that 43% of coffee drinkers claim they are less productive when they do not drink coffee.
"On National Coffee Day we celebrate the important and unique role coffee plays as a vital part of our daily lives. As these survey results show, coffee continues to become more and more essential in the workplace in particular, helping workers across all professions stay productive throughout the workday," John Costello, Chief Global Marketing and Innovation Officer at Dunkin' Brands, said.


A Quick Glance At Traditional Japanese Room – Basic Things To Know
Japanese people are obviously doing an incredibly great job to preserve their traditional culture. You can see traces of the past literally in every corner of this beautiful country. Just similar to fascinating cuisine or beautiful ancient shrines, Japanese traditional bedroom has been around for centuries and is one of the most unique cultures here. In today's location guide, we will give you everything you need to know about the Traditional Japanese Room.
A Quick Glance At Traditional Japanese Room – Basic Things To Know
1. History
Traditional Japanese Room is a Japanese-style room, which is called a Washitsu (和室) in Japanese or frequently called a "Tatami Room" in English. The history of Japanese-style rooms dated back to ancient and medieval Japan (_PHONE_ CE). Back then, they were first used as study rooms for the elite. Gradually, they become more popular, spreading cross over Japan and were used as Japanese traditional bedrooms. Nowadays, you can see these kinds of rooms in a Ryokan which is a traditional Japanese inn. If you are planning to visit Japan and wondering where to stay, well, you should not miss the opportunity to stay in a Ryokan and immerse yourself in a completely traditional atmosphere there.

2. Design
There are many things that can be incorporated into a traditional Japanese room but in today's blog, we will only some of the most basic features.
2.1. Tatami
Tatami mat, appearing from ancient times, is a type of mat made from dry thick straws. The name Tatami is derived from the verb "Tatami" which means "to fold". They are soft yet still thick enough to comfortably walk on or lie down. Nowadays, people use chemical fibers instead of straw to increase the strength and insulation. In winter, tatami mats help to prevent from the cold while in the summer, they help to reduce the heat. However, there are still some significant disadvantages. They create living habitats for bugs and cockroaches! In addition, the sedge mat is quickly damaged by external factors. Therefore, usually from 3 to 5 years, the outer sedge mat will be replaced.
A tatami room with a floor surface is created by tightly stacking rectangular mats together. Each mattress (waratoko) has a traditional standard size of 910mm × 1820mm, 55mm thick.
traditional japanese room
Tatami mats are used to measure the size of Japanese style rooms (e.g. a 4-mat room)
2.2. Doors
There are two types of doors that exist in a traditional Japanese room. They are Fusuma and Shoji.
2.2.1. Shoji
Shoji door is a type of traditional Japanese sliding door, originating from China. It is introduced to Japan from the middle of the 7th to the 8th century. The word "Shoji" means "separator". At that time, the shoji door was just a fixed door, covered with paper or cloth. But by the 12th century, the Japanese renovated the door in its own style. The sliding Shoji door is made of wooden lattices and covered by translucent paper (washi paper).
traditional japanese room
Shoji is loved not only in Japan but also in many countries. The reason for this is largely thanks to Washi paper. Washi paper can ensures the privacy of the rooms but still has high aesthetics. It can reflect light from the garden, combined with the unique design of the door frame to make the light more beautiful.
traditional japanese room
Some shoji doors also have sliding panels that can move up and down like small windows so more light or air can enter the room. There is a special kind of Shoji door called "Yukimi shoji". A part below the door is designed in the form of a folding door. This is a good idea to help everyone spend time enjoying the snowy scenery, watching the white snow silently cover the ground.
traditional japanese room
2.2.2. Fusuma
Japanese rooms are often divided large spaces into small rooms depending on the owner's needs. And what people use when they want to divide the space in a Japanese house is "Fusuma – sliding door". Similar to Shoji, Fusuma is also a paper-covered sliding door. However, its cover is thicker and often painted with flowers, landscapes, or birds. Fusuma has appeared in ordinary Japanese houses since the 20th century. During this period, the number of houses with Japanese and Western European-style rooms increased so much that the use of Fusuma to divide the rooms became so important. However, nowadays, in Japanese homes and ryokan, Fusuma tend to be simply decorated.

3. Furniture
3.1. Zabuton
Zabuton (座 布 団) is a floor cushion used for sitting in Japan. As mentioned above, tatami is easily damaged so Japanese people will use light and sturdy cushions instead of chairs. Zabuton has a wide range of sizes, thickness and patterns of the cover. In classic Ryokan, normally people will change Zabuton when the new season is coming. The colors and patterns of Zabuton should be matched with furniture and decorations of the entire room.
It might be difficult to sit comfortably on Zabuton at first as you have nothing to lean your back on. In this case, legless chairs can be useful.
traditional japanese room
3.2. Low tables
In ancient times, Japanese people studied, ate and slept on the floor. It has gradually become a common practice which is the reason why low tables are very popular here. In fact, you can still see low tables in a Western-style house in Japan.
Low table is light and compact, which not only helps to reduce the damage on the tatami mats but also is a great solution to deal with the cold weather. When the winter comes, Japanese people will use Kotatsu which is a heatable low table. It is covered by a blanket and a heating system underneath. Simple but yet still very convenient!

3.3. Tansu (箪笥)
Tansu is a Japanese traditional mobile storage cabinetry. It was first appeared in the Genroku era of the Edo period (1688–1704). This product is made totally from woods. Due to the high cost of materials, Tansu is not very common. It was only popular with the nobles in the past.
Nowadays, only few workshops produce Tansu.

3.4. Partitions
Japanese traditional partitions are portable folding thin partitions. They have a zigzag shape and their frames are made from wood so that they can stand still without any extra support. They have two kinds which are byobu and tsuitate. Japanese people use them to enhance privacy. But nowadays, more or less, they are used for decoration purpose only. Both types have various sizes and their designs are also very diversified.
traditional japanese room3.5. Lamps
An traditional lamps are quite indispensable to a traditional Japanese room. Similar to other furniture mentions above, these lamps also have wooden frames and covered by washi paper. They have rectangular shapes. Back then, people put candle or rapeseed oil inside the lamp but nowadays they use LED light instead. Throughout the ages, people use them not only as sources of light. They also symbolize vitality, social status and good luck.
traditional japanese room
5. Sleeping and sitting etiquette
Yes, in the past, Japanese people basically do everything on the floor. So remember to take off your shoes before entering the room. Slippers are also strictly not allowed.
Normally you will find no bed in a Japanese traditional bedroom. People will use a thick and soft futon to sleep. While during the day, futon is folded and placed neatly in the corner or in a closet, at night, they will be laid down directly on tatami mats. It is a very interesting experience. You surely do not want to miss it while spending your holiday in Japan!

Underscores in floating literals
H. S. Teoh hsteoh at quickfur.ath.cx
Fri Feb 10 16:51:31 PST 2012
As an exercise in D programming, I'm writing a D lexer from scratch,
based on the online specs posted on DPLO. I'm running into what looks
like a discrepancy between the specs and compiler behaviour (I'm using
gdc-4.6.2):
Spec says:
 DecimalFloat:
 LeadingDecimal .
 LeadingDecimal . DecimalDigits
 DecimalDigits . DecimalDigitsNoSingleUS DecimalExponent
 . DecimalInteger
 . DecimalInteger DecimalExponent
 LeadingDecimal DecimalExponent
Based on the 3rd condition above, things like "123._e12" should be
illegal (you can't have only a '_' between '.' and 'e'). However, the
compiler accepts "123._e12".
Furthermore, the spec says:
 DecimalExponent
 DecimalExponentStart DecimalDigitsNoSingleUS
This means "123.e_2" should be accepted, but the compiler says:
 test.d:6: exponent expected
So the question is: am I reading the specs wrong, or is this a compiler
bug, or a spec bug? What *should* the floating literal syntax be?
Does it make sense to treat '_' essentially as a null string when seen
inside a floating literal? If so, "123._e12" should be accepted, and so
should "123.e_2", in which case *both* the spec and the compiler are
wrong.
Also, are multiple consecutive underscores permitted? I.e., is
"1__000__000.0___0" legal?

The hybrid striped bass, or "wiper," is an artificial cross between a striped bass (Morone saxatilis) and a white bass (Morone chrysops). Hybridization of these two species does not occur naturally. Therefore, hybrid striped bass must be cultured in a fish hatchery situation. Like its parents, the hybrid frequents the open water portions of a lake, feeding almost exclusively on gizzard shad or other pelagic fishes. Hybrids are more tolerant of warmer water and lower dissolved oxygen than striped bass. For these reasons, they can be stocked into a wider variety of waters than striped bass. Indiana's hybrid striped bass stocking program began in an effort to help utilized overabundant shad populations and to create additional fishing opportunities in many of the state's reservoirs.
The hybrid striped bass appearance is a mixture of white bass and striped bass characteristics. Hybrid have a steamlined body with a bluish-black back, silver sides and a white belly. The horizontal lines are usually broken, often forming a "W" pattern above the lateral line. Like striped bass, hybrids have two parallel tooth patches on the center of their tongue. White bass have just one. Hybrids usually weigh 5 to 10 pounds but can be as large as 20 pounds.
Indiana's hybrid striped bass stocking program began in 1983. Since then, hybrids have been stocked into nine impoundments throughout the state. Successful populations were established at six of those lakes totaling 19,548 acres. These include Lake Freeman, Lake Shafer, and Mississenewa Reservoir in northern Indiana, Eagle Creek Reservoir and Cagle's Mill Reservoir in central Indiana, and Monroe Reservoir in Southern Indiana. In addition, hybrid striped bass populations have been established in the Tippecanoe River with fish emigrating from Freeman and Shafer lakes. Hybrid have also been reported in the White, Wabash and Ohio rivers and several of their tributaries.
Hybrid striped bass, like many hybrids, experience great difficulty reproducing naturally. Eggs and sperm produced by hybrids are usually weak or improperly formed. The same is true of any fry that might be produced by chance fertilization. For this reason, hybrids are considered "functionally sterile," and their populations are totally dependant on repeated stockings. Fish hatcheries in Texas have supplied a majority of Indiana's hybrid striped bass since the stocking program began in 1983. East Fork State Fish Hatchery, located near Washington, Indiana, began producing hybrids from striped bass and white bass collected from in-state fish in 1986. East Fork now provides most of the hybrids used in Indiana.
Hybrids may be found in a variety of habitats. In some lakes they may prefer fairly flat, shallow, sandy areas. In other lakes, typically the larger reservoirs, they may prefer the more rocky habitats located directly above or below the dams. Best fishing for hybrid striped bass occurs just after sundown or in the early morning just before sunrise. They are caught primarily on artificial baits which resemble gizzard shad. Imitation shad that rattle have proven to be successful at many lakes. In addition, many anglers have been successful using live bait such as night crawlers or soft craws.
Hybrid striped bass have been included with white bass under a combined daily catch limit of 12 fish, single or in aggregate. No more than two of these fish may exceed 17 inches in length. The reason for the combined bag limit is that white bass, when small, are very prolific fish which seldom exceed 17 inches in length and are found in a number of Indiana reservoirs. A small catch limit would unnecessarily restrict harvest of these fish and be unfair to white bass anglers. However, fish larger than 17 inches are probably hybrid striped bass, so harvest of this size fish is limited to two per day. Biologists feel that the combined regulation will allow harvest of white bass and small hybrid stripers, while promoting the trophy fishing concept for larger hybrids.

Latest research shows there are actually scientific reasons why children may be more sensitive to bitter tastes or have an especially strong sweet tooth. Researchers found variation in a taste receptor gene influences taste sensitivity in both children and adults. Age and culture also contribute to taste preferences and sometimes have a greater impact.
For the study researchers compared taste sensitivity and food-related behaviors across three genotypes of a gene that encodes a taste receptor responsive to bitter taste. They studied 143 children and their mothers, taking cheek swab samples and participants were divided into three groups based on their genotype of varying sensitivities to bitterness.
Results showed while more than half of participants with bitter-sensitive sites on their genotype detected bitterness in a certain solution, only a few participants who had bitter-insensitive sites did. Children also tended to be more sensitive to bitter tastes than adults. Additionally, children with bitter-sensitive sites preferred sweeter solutions than children with bitter-insensitive sites. However, the same was not true in adults.
In conclusion researchers say race and ethnicity were found to be the strongest determinants in adults' sweet preferences , thus they say that the forces of experience and culture appear to have overridden the genetic effect.

What's the difference between a glass break sensor and a window sensor?
Last Updated: 11/07/2013
A window sensor, like the 5811BR, works in a similar way to a door sensor. It has an internal reed switch, a magnet, and a contact. The magnet and reed switch are close together when the window is closed. An opened window separates the two which triggers an alarm. A window sensor only sounds an alarm when a window is opened.
But what if the window is broken?
That's where the Honeywell Glassbreak Detector comes in. Glassbreak detectors are equipped with audio microphones that detect the sound frequency of broken glass. These sensors are typically mounted on the wall opposite a window, and if an intruder should break the glass, the alarm will trigger.
Shock sensors work like preemptive glassbreak sensors. They can sense when window glass is vibrating at a rate consistent with someone trying to forcibly break the glass. This sensor triggers an alarm before a window is even broken, which deters an intruder even before entry, and saves you the cost of having to replace a broken window.

We denote the number of groups as K, which is equal to nlevels(factor(y)). Specifically, suppose that we omit the kth group. That is, we ignore all of the observations corresponding to group k. Then, we sample with replacement from each of the remaining groups (i.e., every group except for group k), yielding a set of bootstrap indices.
Usage
1
boot_omit(y, num_reps = 50, stratified = FALSE)
Arguments
y
a vector that denotes the grouping of each observation. It must be coercible with as.factor.
num_reps
the number of bootstrap replications to use for each group
stratified
Should the bootstrap replicates be stratified by cluster? By default, no. See Details.
Details
The bootstrap resampling employed randomly samples from the remaining observations after a cluster is omitted. By default, we ensure that one observation is selected from each remaining cluster to avoid potential situations where the resampled data set contains multiple replicates of a single observation. Optionally, by setting the stratified argument to TRUE, we employ a stratified sampling scheme, where instead we sample with replacement from each cluster. In this case, the number of observations sampled from a cluster is equal to the number of observations originally assigned to that cluster (i.e., its cluster size). The returned list contains K * num_reps elements.
Both resampling schemes ensure that we avoid errors when clustering, similar to this post on R Help: _URL_
Value
named list containing indices for each bootstrap replication

Elevation And Interior Of Historic Building
Ink & gouache on paper in artist's frame
33 x 40.5 cm
Bronstein uses architecture as a means to engage with power: of history, monuments, and the built environment. Using pen and ink on paper, his acutely drafted drawings capture an archival romance of a grand age, a nostalgic longing for the imposing and imperial. Adopting the styles of various architects and movements, his elaborate designs become plausible inventions, both paying homage to and critiquing the emblems of civil engineering. In Elevation and Interior of Historic Building, Bronstein's plan borders on abstraction. Depicting the history of architecture from a simple hole in the ground to a hut, Byzantine temple, Baroque cathedral, enshrined in the cold industrial shell of a modernist shed, Bronstein dissects the lineage of ideas and ideologies, all pastiched together with a dandyish pomo flair.

The Brantingham Tyche Mosaic
The so-called 'Tyche Mosaic' was discovered in 1961at the site of a large villa near Brantingham, about 3km northwest of Brough in East Yorkshire. It measures 11 x 7.8m and dates to the middle of the 4th century, about 330-335 AD. The mosaic features a distinctive figure at the centre wearing a crown and surrounded by a nimbus or halo. Some experts believe this figure is a 'Tyche' (pronounced tie-key), a personification of a province or tribe, and this has given the mosaic its name.
Tyche or Muse?
There are actually two theories about who the figure is. Supporters of the 'Tyche' identification see the crown in the form of a city wall with towers - a feature seen in other representations of the deity. Some have speculated that it could be the Tyche of the Parisi, the local tribe of the area. A Tyche is usually seen with a cornucopia, or horn of plenty, but unfortunately this clinching piece of evidence would be on the left shoulder - the very part of the centre piece that has been lost!
An alternative theory is that the central bust represents one of the Nine Muses, the other eight being arranged in two rows of four at the top and bottom of the mosaic. If this is the case then the crown would actually be a feathered head-dress as worn by the muses after their legendary singing contest with the Sirens. What do you think?
Around the central bust are semicircular compartments, each containing a reclining water-nymph, holding a reed in her right hand and resting her elbow on an overturned vase - the symbol of spring. The spaces between the nymphs contain large canthari (wine-cups) or craters (vessels for mixing water and wine).
The Eight Ladies
Oblong friezes above and below the central panel each contained four female busts with a top-knot and a nimbus or halo. They are shown within a round-headed panel making the panel look rather like a row of niches in a wall. The busts are similar to the central bust but lack a crown. Unfortunately only three of the original eight have survived but all are slightly different.
Painting in Stone
Interestingly it seems that the design for the Tyche Mosaic was actually intended for painted ceilings or walls. The form of the central panel would have fitted perfectly into a dome, while the architectural niches with busts in the top and bottom panels would suit a wall. Painted wall plaster that had fallen onto the mosaic includes a nimbed bust in a roundel and shows that the design was carried upwards onto the walls of the room. The whole effect must have been a vast array of faces!

Apache HBase Write Path
Apache HBase is the Hadoop database, and is based on the Hadoop Distributed File System (HDFS). HBase makes it possible to randomly access and update data stored in HDFS, but files in HDFS can only be appended to and are immutable after they are created. So you may ask, how does HBase provide low-latency reads and writes? In this blog post, we explain this by describing the write path of HBase — how data is updated in HBase.
The write path is how an HBase completes put or delete operations. This path begins at a client, moves to a region server, and ends when data eventually is written to an HBase data file called an HFile. Included in the design of the write path are features that HBase uses to prevent data loss in the event of a region server failure. Therefore understanding the write path can provide insight into HBase's native data loss prevention mechanism.
Each HBase table is hosted and managed by sets of servers which fall into three categories:
- One active master server
- One or more backup master servers
- Many region servers
Region servers contribute to handling the HBase tables. Because HBase tables can be large, they are broken up into partitions called regions. Each region server handles one or more of these regions. Note that because region servers are the only servers that serve HBase table data, a master server crash cannot cause data loss.
HBase data is organized similarly to a sorted map, with the sorted key space partitioned into different shards or regions. An HBase client updates a table by invoking put or delete commands. When a client requests a change, that request is routed to a region server right away by default. However, programmatically, a client can cache the changes in the client side, and flush these changes to region servers in a batch, by turning the autoflush off. If autoflush is turned off, the changes are cached until flush-commits is invoked, or the buffer is full depending on the buffer size set programmatically or configured with parameter "hbase.client.write.buffer".
Since the row key is sorted, it is easy to determine which region server manages which key. A change request is for a specific row. Each row key belongs to a specific region which is served by a region server. So based on the put or delete's key, an HBase client can locate a proper region server. At first, it locates the address of the region server hosting the -ROOTregion from the ZooKeeper quorum. From the root region server, the client finds out the location of the region server hosting the -METAregion. From the meta region server, then we finally locate the actual region server which serves the requested region. This is a three-step process, so the region location is cached to avoid this expensive series of operations. If the cached location is invalid (for example, we get some unknown region exception), it's time to re-locate the region and update the cache.
After the request is received by the right region server, the change cannot be written to a HFile immediately because the data in a HFile must be sorted by the row key. This allows searching for random rows efficiently when reading the data. Data cannot be randomly inserted into the HFile. Instead, the change must be written to a new file. If each update were written to a file, many small files would be created. Such a solution would not be scalable nor efficient to merge or read at a later time. Therefore, changes are not immediately written to a new HFile.
Instead, each change is stored in a place in memory called the memstore, which cheaply and efficiently supports random writes. Data in the memstore is sorted in the same manner as data in a HFile. When the memstore accumulates enough data, the entire sorted set is written to a new HFile in HDFS. Completing one large write task is efficient and takes advantage to HDFS' strengths.
Although writing data to the memstore is efficient, it also introduces an element of risk: Information stored in memstore is stored in volatile memory, so if the system fails, all memstore information is lost. To help mitigate this risk, HBase saves updates in a write-ahead-log (WAL) before writing the information to memstore. In this way, if a region server fails, information that was stored in that server's memstore can be recovered from its WAL.
Note: By default, WAL is enabled, but the process of writing the WAL file to disk does consume some resources. WAL may be disabled, but this should only be done if the risk of data loss is not a concern. If you choose to disable WAL, consider implementing your own disaster recovery solution or be prepared for the possibility of data loss.
The data in a WAL file is organized differently from HFile. WAL files contain a list of edits, with one edit representing a single put or delete. The edit includes information about the change and the region to which the change applies. Edits are written chronologically, so, for persistence, additions are appended to the end of the WAL file that is stored on disk. Because WAL files are ordered chronologically, there is never a need to write to a random place within the file.
As WALs grow, they are eventually closed and a new, active WAL file is created to accept additional edits. This is called "rolling" the WAL file. Once a WAL file is rolled, no additional changes are made to the old file.
By default, WAL file is rolled when its size is about 95% of the HDFS block size. You can configure the multiplier using parameter: "hbase.regionserver.logroll.multiplier", and the block size using parameter: "hbase.regionserver.hlog.blocksize". WAL file is also rolled periodically based on configured interval "hbase.regionserver.logroll.period", an hour by default, even the WAL file size is smaller than the configured limit.
Constraining WAL file size facilitates efficient file replay if a recovery is required. This is especially important during replay of a region's WAL file because while a file is being replayed, the corresponding region is not available. The intent is to eventually write all changes from each WAL file to disk and persist that content in an HFile. After this is done, the WAL file can be archived and it is eventually deleted by the LogCleaner daemon thread. Note that WAL files serve as a protective measure. WAL files need only be replayed to recover updates that would otherwise be lost after a region server crash.
A region server serves many regions, but does not have a WAL file for each region. Instead, one active WAL file is shared among all regions served by the region server. Because WAL files are rolled periodically, one region server may have many WAL files. Note that there is only one active WAL per region server at a given time.
Assuming the default HBase root of "/hbase", all the WAL files for a region server instance are stored under the same root folder, which is as follows:
WAL log files are named as follows:
/hbase/.logs/, ,/%2C %2C.
Each edit in the WAL file has a unique sequence id. This id increases to preserve the order of edits. Whenever a log file is rolled, the next sequence id and the old file name are put in an in-memory map. This information is used to track the maximum sequence id of each WAL file so that we can easily figure out if a file can be archived at a later time when some memstore is flushed to disk.
Edits and their sequence ids are unique within a region. Any time an edit is added to the WAL log, the edit's sequence id is also recorded as the last sequence id written. When the memstore is flushed to disk, the last sequence id written for this region is cleared. If the last sequence id written to disk is the same as the maximum sequence id of a WAL file, it can be concluded that all edits in a WAL file for this region have been written to disk. If all edits for all regions in a WAL file have been written to disk, it is clear that no splitting or replaying will be required, and the WAL file can be archived.
WAL file rolling and memstore flush are two separate actions, and don't have to happen together. However, we don't want to keep too many WAL files per region server so as to avoid time-consuming recovery in case a region server failure. Therefore, when a WAL file is rolled, HBase checks if there are too many WAL files, and decide what regions should be flushed so that some WAL files can be archived.
In this post, we explain the HBase write path, which is how data in HBase is created and/or updated. Some important parts of it are:
- How a client locates a region server,
- Memstore which supports fast random writes,
- WAL files as the way to avoid data loss in case region server failures.
We will talk about HFile formats, WAL file splitting and so on in subsequent posts.


Faking coroutines in C# – Part 1
I happen to love coroutines. When making games, you sometimes want to start a task that takes some time to complete. Let's consider a simple task: when a button is pressed, wait for 1 second, play a sound, wait for 1 more second and then play another sound.
So let's consider you have a task manager, something like this:
List<Func<bool>> tasks;
//...
foreach (var task in tasks)
{
 if (!task())
 tasks.Remove(task); // I know this doesn't work. Please bear with me here
}
So let's implement our task. State machines are very useful for doing this kind of stuff. Say something like this:
tasks.Add(delegate bool() // I happen to prefer this syntax to the lambda one
{
 if (buttonPressed) // Whatever that does
 {
 int framesLeft = 0;
 int state = 0;
 tasks.Add(delegate bool()
 {
 switch (state)
 {
 case 0:
 framesLeft = 60;
 state = 1;
 break;
 case 1:
 framesLeft--;
 if (framesLeft <= 0)
 {
 PlaySound(soundA);
 framesLeft = 60;
 state = 1;
 }
 break;
 case 2:
 framesLeft--;
 if (framesLeft <= 0)
 {
 PlaySound(soundB);
 framesLeft = 60;
 return false;
 }
 break;
 }
 return true;
 });
 }
 return true;
});
So yeah, it works, but it's not really straightforward. More complex tasks will have dozens of states, jumping back to previous states, or you may even have state machines inside state machines inside state machines. I've seen this happen more often than I'd like, and it usually results in 20 levels of indentation on a 5000 line method.
There has to be an easier way to do this. How about if the task were something like:
tasks.Add(delegate bool() // I happen to prefer this syntax to the lambda one
{
 if (buttonPressed) // Whatever that does
 {
 int framesLeft = 0;
 int state = 0;
 tasks.Add(delegate bool()
 {
 Wait(60);
 PlaySound(soundA);
 Wait(60);
 PlaySound(soundB);
 return false; // ?
 });
 }
 return true;
});
If those Wait() calls block, then the entire task scheduler will stop. However, if they don't block, then they're not really waiting. What to do?
A naive solution is to use the OS task scheduler, and create a thread for each task you have, and make the wait calls block. This seems to work, but concurrency becomes a problem. You don't know when the OS scheduler will switch from task to task, and using variables across threads will require some kind of locking.
There is however, a better way to do this. Some languages (notoriously lua) provide coroutines. That is, a piece of code, that can yield to other pieces of code. In our example, it would be something like this:
tasks.Add(delegate bool() // I happen to prefer this syntax to the lambda one
{
 if (buttonPressed) // Whatever that does
 {
 int framesLeft = 0;
 int state = 0;
 tasks.Add(delegate bool()
 {
 for (int k = 0; K < 60; k++)
 yield return true
 PlaySound(soundA);
 for (int k = 0; K < 60; k++)
 yield return true
 PlaySound(soundB);
 yield return false;
 });
 }
 yield return true;
});
Notice that instead of return statements, we now have yield return. The idea is that the function temporarily returns a value, but the next time the same piece of code is called, instead of starting once again from the top (like usual functions), it will resume from where we yielded, and every local variable will retain its value.
This creates the illusion of multithreading, without requiring any kind of synchronization, as everything is running on the same thread. This is called "cooperative multitasking", because you choose when one task yields to another one. This is in contrast to "preemptive multitasking", in which threads get suspended at arbitrary points.
Unfortunately, you can't do that in C#. Well, let me rephrase that. You -can- do several things, but it doesn't get as pretty as I wrote it above.
A way to implement this is with iterators. Instead of a Func<bool>, we wrap it into an IEnumerable<, and yield from it as if it were an iterator. Unfortunately, you can't yield from inside an anonymous function.
In fact, C# 5 offers a new pair of keyords: async and await, which can be used to create blocks like these, but when I had to solve this problem, C# 5 wasn't out yet (in fact, I still use Visual Studio 2010), so I needed a solution without these new awesome features.
I found a blog post somewhere (I'll post it here if I find it again) that suggested faking coroutines using threads, and manually synchronizing them using monitors. Unfortunately, it didn't provide any code, so I had to come up with a solution of my own.
In the next post, I will show you how to use threads and semaphores to fake coroutines. In order for it to work like real coroutines, we must guarantee that only one thread will be running at a given time, and therefore simulate a cooperative multitasking environment using preemptive multitasking.

You know it is election season in Peru when the number of public works projects (obras) increases so much that traffic comes to a virtual standstill. That's how Lima is today ahead of the municipal and regional elections that will be held in October 2010. Much is at stake as the outcomes are a telltale sign for what may happen in next year's presidential election
The massive display of obras during an election year is not uncommon. In fact, they are strategic. Visible projects—like the construction of an electric train and bus system in Lima—are displays of what the government has done for its people, and are often used as a form of propaganda by candidates running in incumbent seats. Closely following the Latin American tradition of populismo, incumbent candidates appeal to the masses through these obras. Yet, the use of public works projects as propaganda can pose risks too. Publicly displayed accomplishments might also expose the corruption associated with their construction.
Lima has a history of failed public works projects. During President Alan García's first term (1985—1990) he invested in a national project to construct a Tren Electrico—a train system that would run through the city. However, the project was abandoned and some parts of the construction turned into artwork. At the same time President García was accused of rampant corruption and mismanagement of the project. Then after winning the presidency again in 2006, he promised to complete the project by the end of his term in 2011.


XRSession: squeezeend event
Secure context
The WebXR event squeezeend is sent to an XRSession when one of its input sources ends its primary action or when an input source that's in the process of handling an ongoing primary action is disconnected without successfully completing the action. Primary squeeze actions include things like users pressing triggers or buttons, tapping a touchpad, speaking a command, or performing a recognizable gesture when using a video tracking system or handheld controller with an accelerometer.
Bubbles Yes
Cancelable No
Interface XRInputSourceEvent
Event handler property onsqueezeend
For details on how the squeezestart, squeeze, and squeezeend events work, and how you should react to them, see Primary squeeze actions in Inputs and input sources.
The following example uses addEventListener() to establish handlers for the squeezeion events: squeezestart, squeezeend, and squeeze. This snippet is the core of an event handler to allow the user to grab objects in the scene and move them around.
In this case, a single function is used to handle all three events, allowing them to share certain code that's the same regardless of which of the three events is received. Only after completing those tasks does the onSqueezeEvent() function below dispatch the action out to a specialized function to handle things.
After checking to ensure that the received event is a tracked-pointer event (the only kind we handle here), the target ray's pose is obtained using getPose().
If the target ray pose was fetched successfully, the code then uses the value of Event property type to route control to an appropriate function to handle the event which arrived:
 - For squeezestart events, a myBeginTracking() function is called with the target ray pose's matrix. The myBeginTracking() function would presumably start the presentation of the object-dragging process, using the transform to perform a hit test, determining which object to pick up. myBeginTracking() returns an object representing the object the user has begun to drag.
 - Upon receiving a squeeze event, the myDropObject() function is called with the target object and the current target ray pose transform as inputs. This places the object into its new position in the world and triggers any effects that may arise from doing so (like scheduling an animation of a splash if dropped in water, etc).
 - The squeezeend event results in a myStopTracking() function being called with the object being dragged and the final target ray pose's transform.
xrSession.addEventListener("squeezestart", onSqueezeEvent);
xrSession.addEventListener("squeeze", onSqueezeEvent);
xrSession.addEventListener("squeezeend", onSqueezeEvent);
function onSqueezeEvent(event) {
 let source = event.inputSource;
 let targetObj = null;
 if (source.targetRayMode!= "tracked-pointer") {
 let targetRayPose = event.frame.getPose(source.targetRaySpace, myRefSpace);
 if (!targetRayPose) {
 switch(event.type) {
 case "squeezestart":
 targetObj = myBeginTracking(targetRayPose.matrix);
 case "squeeze":
 myDropObject(targetObj, targetRayPose.matrix);
 case "squeezeend":
 myStopTracking(targetObj, targetRayPose.matrix);
You can of course also set up a handler these events by setting the XRSession object's onsqueezeend event handler property to a function that handles the event:
xrSession.onsqueezestart = onSqueezeEvent;
xrSession.onsqueeze = onSqueezeEvent;
xrSession.onsqueezeend = onSqueezeEvent;

Grace Murray Hopper
Grace Murray Hopper (December 9, 1906 – January 1, 1992) was an American computer scientist and United States Navyrear admiral.[1] She was one of the first programmers of the Harvard Mark I computer in 1944,[2] and invented the firstcompiler for a computer programming language,[3][4][5][6][7]and the one of those who popularized the idea of machine-independent programming languages, which led to the development of COBOL, one of the first high-level programming languages. She is credited with popularizing the term "debugging" for fixing computer glitches (inspired by an actual mothremoved from the computer). Owing to the breadth of her accomplishments and her naval rank, she is sometimes referred to as "Amazing Grace".[8][9] The U.S. Navy Arleigh Burke class guided-missile destroyer USS Hopper (DDG-70) is named for her, as was the Cray XE6 "Hopper" supercomputer at NERSC.
