How to mine Sia Coin using graphic cards?
How to mine Sia Coin using graphic cards?
The Sia network aims to create a decentralized data storage network, using free space on disks.
Sia uses blockchain technology as a transaction layer for her network, enabling the purchase and sale of hosting power in a secure and trusted way. Smart contracts provide encryption and data transfer, leaving no room for interference by third parties.
Sia uses Siacoin (SC) cryptocurrency. The initial prize for the block was 300,000 SC. Each subsequent prize for a block is one smaller than the previous one (299.999, 299.998, etc.). When the prize for mining the block reaches 30,000 (at 270,000 block), each next prize will be 30,000 SC. The block is mined every 10 minutes.
In this guide we will use the "ccminer" software. So, lets do it!
1. Installation
There are several different programs to mine Siacoin, but most of them offer similar features and performance. In this guide, we use the ccminer program, but if you like, you can use another program - more on the official site of Sia.
Step 1: Click here to go to github - CCminer 8.00 from KlausT. After entering the website, select your operating system from the list (in our case it is 64-bit Windows 10).
Step 2: After the download, extract it, then create a folder called "siacoin miner".
Step 3: Exit the folder and select Pool, as you can see in the
Step 4: Now you will have to create the batch file, so first open the Notepad, copy the following command and paste into the Notepad. This command will allow you to connect to the Pool:
ccminer.exe -a sia -e --url=stratum+tcp:// -u YourWalletAddress.YourName -i 28
This is just an example, below I've written examples for specific locations:
 - if you're from Asia / Pacific, replace "" with ""
 - if you're from Europe, replace "" with ""
 - if you're from the USA, replace "" with ""
 - if you are from the East, leave ""
Where "YourWalletAddress" is entered, you paste your Sia wallet address.
(To be able to mine, you will need a Siacoin wallet The fastest way to create a Siacoin wallet is to use the exchange, eg Binance. You can sell your coins there immediately.)
And where 'YourName' is, enter your name. (It is so logical that I do not know why I write about it :D).
(Leave the dot between the address and the name)
At this moment, we need to save this text file as a batch file. Click on the "file" tab and select "save as", then select the folder you created, (for us it is "siacoin miner") save as "Start.bat" (".bat" is a diminutive from batch) and press "save".
2. Start mining
Step 1: Open the folder "siacoin miner" and double click on the "Start.bat" file.
That's all. After starting mining, you can see your progress by visiting, next to our address Siacoin in "address field" and press "go":


Solving The Trigger Challenge
In week three of Eliot's MongoDB World Weekly Challenge, you were tasked with setting up MongoDB so that actions were executed as data was inserted into the database using Triggers. Triggers are great for reacting to changes in the data so let's look at how we can put them to work, solve that problem and learn more about this great Stitch feature.
We will assume you've already got your database cluster created previously. If not, create an MongoDB Atlas M0 tier free trial cluster to work though this solution.
Create the Stitch Application
Before we start working with our data we need to create a Stitch application which will host our Database Trigger.
Create Stitch App
The application should be linked to your cluster and the deployment model can be local or global. Once the application is created, a unique App ID will be created. This App ID is the answer to question one. See. It is that simple.
Getting the App ID
Now that we have our Stitch application linked to our cluster, we can create the Stitch Trigger.
Create the Stitch Trigger
A Stitch Trigger uses MongoDB change streams to react to events in our system and push these notifications to downstream systems. In our use case, we are capturing real-time inserts and counting sales that meet our given criteria.
Select Triggers from the left-hand menu, we will use the Database Trigger for this use case. This is just one of three types of triggers that Stitch offers. The Database Trigger generates events based on database operations such as inserts, updates, and so on so you can act on database changes. The authentication trigger executes based on Stitch user events such as create and login so you can act on user activity. Finally, a scheduled trigger will execute Stitch Functions at a user-defined time interval. These are useful for database maintenance commands such as cleaning up old data or creating reports at set times. The Stitch Functions are executed in a the application's context so they also have access to all the third-party services offered by Stitch.
Knowing the three types of triggers offered by Stitch and how to use them not only allows us to be more productive developers but is also the key to answering the last question.
Adding a Trigger
Let's give our Database Trigger a name, like any good variable name the more descriptive the better. For our challenge, we want to count all documents created in the sales collection of the sample_supplies database which originated from the Denver or San Diego store locations which were purchased in store or on the phone and used a coupon.
For this trigger we will only look at inserts against the sales collection in the sample_supplies database. The great thing about this is the database does not have to exist for the trigger to start. With this current configuration, the trigger will process each sale as it comes in the proper order, but we want to find specific data, so before we create our new function, let's scroll down to the advanced features and update our match expression:
Match Expression in Trigger
Now the trigger will only fire when new a new sales document is created which matches the search criteria:
 "fullDocument.storeLocation": {
 "$in":["Denver","San Diego"]
 "$in":["In store","Phone"]
The fullDocument is a field set in the change stream which contains the newly created document. We can search for specific fields of this full document, and only those documents that match will be sent to the function (which we will create next) for processing. Something worth noting is that we are getting the full document even though we did not turn on full document processing. This is because a create will create a change event for the trigger with the full document. Compare this with an update which will only return the fields that have changed unless we explicitly ask for the full document. When we do that, it forces the trigger do a lookup on the original document.
 - A common mistake we saw was the omitting of the fullDocument field in the match expression. The fullDocument field is required as the match is being run not on the document that fired the trigger but rather on the change event document that the trigger captured.
 - One common match expression we saw had explicit use of the $and operator. A match in MongoDB uses a logical AND by default when looking at multiple fields. Calling it out can make things more readable, so this is more of a code styling preference and no points were removed if a different style was used.
Now, of course, you could perform a match like this in your function but it would make the function needlessly complex. More importantly, every new sale document would call the function, meaning it would do unnecessary extra processing.
When the trigger conditions are met, we want this trigger to execute a Stitch Function. Stitch Functions are written in JavaScript and execute in a serverless style on the Stitch platform.
Create the Stitch Function
For this part of the challenge, we simply want a count of the documents that met the criteria. We could do a query after all the sales have been loaded, but using a trigger with a function gives us a "real-time" or "at the moment" view of the data. We could expand on this example to create real-time dashboards. We could even use Charts as we saw in the previous challenge.
From the Stitch Trigger page, let's link a function. We can link an existing function or create a new function. For this challenge, we will create a new function:
Creating a Linked Function
This will expand an editor window with the prepopulated code for a trigger:
Initial code template for a Function
The code template here shows some useful examples of how to work the with the changeEvent that is sent to the function. There's some great information here, but for this challenge we will not be using any of it. We simply need to get a total count of the number of times a document was created with the criteria described previously. We can't, though, just add one to a variable. Variables created in the function scope cease to exist when the function has been run. That means we need to store the running total in the database. Using the global context associated with our Stitch application we can get a handle to a collection where we will write that running total:
exports = function(changeEvent) {
 /* 1 */
 let collection =
 /* 2 */
 return collection.updateOne(
 {_id: 1},
 {$inc: {total: 1}},
 {upsert: true}
 ).then(result => {
 return result;
 }).catch(err => {
 return err;
The first line, /* 1 */ gets the MongoDB Stitch service using the mongodb-atlas name. This name is created by default. We then get the sample_supplies database from the MongoDB Stitch service. Finally, we get a handle to a collection called sales_output which we store in the variable collection.
On second line, /* 2 */, we use the updateOne method of the collection object to increment the value in the total field by 1 for a single document with a query filter of {_id: 1}. If this document does not exist, it will be created because of the {upsert: true} arguments.
The updateOne method returns a promise. We chain the.then() method to simply return the results to the caller. We also chain the.catch() method, which catches errors, to return the error to the caller. Note that the caller, in this case, is the trigger we created.
This function is another of the answers we were looking for though we are not looking for the exact lines above, just something similar.
A couple of common mistakes (not necessarily wrong, just extra code) we saw were:
 - There was an extra check to the changeEvent object for an "insert" event. This check is not needed if we configure our trigger to only notify insert events.
 - There were validations on the changeEvent.fullDocument field to ensure the document met the query criteria. This is also not needed if we setup our match criteria correctly.
 - There were a couple entries where the updateOne method calls used an open query filter of {}. Although this does not cause an issue with this challenge as we are only storing one document in the collection, it could introduce a bug when we have more writers executing on the collection. We did not deduct any points for this difference.
Though these mistakes may be considered cosmetic, it is a best practice to only include meaningful instructions in cloud based serverless environments like Stitch Functions. In the cloud computing world we are charged for compute time of each function, reducing this compute time not only improves performance but can also save money (albeit minimal for each call) over time.
There's one last step to go in creating the function. Once we save it, let's go and edit the Function's settings. On the left hand menu click Functions, select the our newly created function, and go to its Settings page.
Function Settings
Ensure the function is marked as private so that only internal services can execute this function. Then enable run as system which allows this function to bypass any service rules that might be configured. We will learn more about services rules in an upcoming challenge.
Once finished and the changes are saved, we are now ready to load our sample data. Go back to the Atlas application page and load the sample data for the cluster.
Loading Sample Data
As the data loads, it will create various sample databases and collections. One of those will be the sample_supplies database and its sales collection where it will insert new documents, firing our trigger which in turn will call our function. Once the data is completely loaded we can go the Collections tab to view our data. Go into the sample_supplies database and look at the sales_output collection. You should see something like this:
Results in the sales_output collection

Mayapples - umbrellas for elves?
Mayapple
Mayapple
Hiking in the woods this spring, you may encounter a sight that may make you wonder "Did a convention of elves loose their umbrellas?" Those glossy green umbrellas popping up from the forest floor are mayapples, Podophyllum peltatum. They are found in the woodlands from western Quebec and Minnesota to Florida and Texas. Mayapples are found in clumps or colonies because the plant spreads by rhizomes. Rhizomes are stems that grow horizontally under the surface of the ground. From these stems, shoots and roots are produced.
In the Barberry family, these plants are one of the easiest spring wildflowers to identify - having smooth dark green leaves that are wrapped around stems. The leaves are circular in shape with five to seven lobes. You can tell if a mayapple will produce a flower by looking at the number of leaves it has. One leaf, it won't flower, two leaves it will flower. It can take up to four years for a mayapple to mature and produce a flower.
The waxy white flower has six petals and is about 2" in diameter. The 2" long fruit is sphere to lemon shaped. It will change in color from green to yellow as it ripens. The fruit of the mayapple is considered to be the only non-toxic part of the plant. Its fruit can be incorporated into marmalades, jellies, pies and drinks.
Historically, Native Americans used the mayapple as a powerful laxative, to get rid intestinal worms, as a wart cure-all and as an insecticide on crops. They would gather the rhizomes in the fall, dry and then crush them into a powder. Care had to be taken because only certain parts of the rhizome are safe; the others can be quite toxic. Currently, the USDA lists mayapple as 'unsafe' and advises against using it medicinally at home. Modern science has discovered that extracts of mayapple can be used in treatment of certain cancers and tumors.
From elfin umbrellas to cancer busters, mayapples have a myriad of uses. They are also one of the easiest spring wildflowers to be identified. On your next ramble into the woods, check under those leaves for the flower and fruit!


Question: Do Google Voice Calls Show On Phone Bill?
Why do Messenger calls show on call log?
Facebook admitted on Friday (March 23) that its Android apps for Facebook Lite and Facebook Messenger uploaded logs of users' call and text-message histories to Facebook servers.

Multivariate geographical characterisation of Slovak fruit distillates through mineral elements profile
Keywords:fruit distillate, mineral element, principal component analysis, discrimination
Mg, Ca, Zn, Cu, K and Na were determined in some species of Slovakian fruit distillates by atomic absorption spectrometry with the aim to differentiate the spirit drinks according to geographical origin. Potassium, sodium and copper were found as markers with the highest concentrations and variability in the distillates, namely in the apricot and grape brandy. Using the multivariate statistics of principal component and canonical discriminant analysis enabled relative effective differentiation of samples according to their regional origin. Prediction ability of the model resulted in more than 80% of correctly classified samples of the fruit distillates into the relevant Slovakian regions.

Task uvsector will flag a sector of visibility data with a given u-v position angle (or hour angle). While you can give the position angle of the sector to be flagged directly (via the angle parameter), it is more convenient to indicate the position angle indirectly via the stripe direction in an image. How do you specify a stripe direction? You do this by specifying a long, thin region in a image. Normally you will generate the region by using cgcurs (see Section 17.3 for more information on cgcurs). With cgcurs, you display a greyscale of the image, and then use a cursor to selection a long, thin, region containing the crest of a single stripe. The selected region is then written into a text file, cgcurs.region. While this may be a rather odd way to define a direction, it allows uvsector to use the interactive facilities of cgcurs.
Typical inputs to use cgcurs are
|in=vela.icln||Input image (probably CLEANed).|
|range=||Set the range to highlight the stripes.|
|device=/xs||PGPLOT device - Xwindows here.|
|options=region||Define a region of interest.|
The width of the sector that uvsector flags is given as an angle (in degrees) via the width parameter. Remember that 1 degree is equivalent to 4 minutes of observing time, so do not set it to any value larger than you need. Normally you would set this to a few degrees, based on your confidence in the accuracy of the stripe direction. The default is 5 degrees.
As uvsector flags a sector, if your input visibility data-set contains multiple configurations, data within that sector for all configurations will be flagged by default. Generally this is not what you are likely to want. If you know which configuration contains the bad data, you can use the select keyword to ensure just that configuration is affected. Selecting by time is probably the easiest.
The breadth of a stripe also contains useful information - a glitch in just
the short baselines will cause a broad stripe, whereas a glitch in just the
long baselines will cause a narrow stripe separation. A glitch in just one
baseline will give a two dimensional sinusoid.
Given the separation
between stripes, you could make an approximate calculation of the corresponding
u-v radius of the bad data.
For a stripe separation (crest to crest) of x arcseconds, the corresponding
u-v radius is
|vis=vela.uv||Visibility data to be flagged.|
|angle||Leave unset if defining position|
|angle by a stripe direction.|
|in=vela.icln||The image containing stripes,|
|used only for its coordinate information.|
|_EMAIL_||A long, thin, region along the crest|
|of a stripe.|
|width=3||Flag data over 3 degrees (12 minutes of time)|
|select||Leave unset to flag all data in the sector,|
|select=uvrange(8,12)||Flag data within the sector and between 8 to 12|

THE first-ever official State commemoration of the 1913 Lockout will take place in Dublin this summer.
THE Government is making arrangements which will involve the State in a major event to mark the centenary of the dramatic events that shook the city for almost six months.
One-third of the population suffered severe hardship after employers locked out their workers in a widespread dispute stemming from efforts to curb the growth of trade unions.
Three people were killed and hundreds more injured by police baton charges in violent incidents during the dispute.
Author Padraig Yeates (66), a leading member of the 1913 Commemoration Committee, told the Herald the State has never taken an official role in commemorating the Lockout events. The official commemorations are likely to centre on the events of August 1913, when hundreds of people were injured when police baton-charged crowds on O'Connell Street, then known as Sackville Street
The previous night, two men died from blows from police batons in riots on Burgh Quay and Eden Quay.
A third man died after being batoned in his home in Foley Street during police raids that weekend.
The State commemoration will also officially acknowledge the role of the labour movement in the turbulent decade which followed and its role in securing Irish independence, said Mr Yeates.
An Post will be issuing commemorative stamps.

Discovering Amsterdam's Oldest Bridge: A Look at Torensluis
Torensluis is not just a bridge; it's a piece of Amsterdam's history. As the oldest bridge in the city, it has seen centuries of change and development. From its unique design to its cultural and historical significance, there is much to explore and discover about Torensluis.
The Torensluis is a historic bridge over Amsterdam's Singel Canal that has stood the test of time. It is the oldest original stone bridge in Amsterdam and the widest of its kind.
Bridge number 9 (Brug Negen) Torensluis is an arch bridge over the Singel in the centre of Amsterdam near Dam Square and at 42 meters it is one of the widest in the city. The reason for this is that previously there was a tower on the bridge, the Jan Roodenpoortstoren.
Another reason it is quite wide is that originally in 1648 during the design of the bridge the plan was to build shophouses on the wide bridge similar to the Rialto Bridge in Venice and bridges across the Thames in London. It is not clear if this plan ever came to fruition though it seems unlikely as except for a couple of houses there is no documentary evidence for this.


nextRun will be set to 0.
This is useful for jobs which have to be fired from time to time.
To fire such an asynchronous job, just set nextRun=NOW() and wait for the next system cron run.
If such a job is running and a new nextRun=NOW() is applied, the 'AutoCron' job will be fired again during the next system cron run.
Type: Mail
Currently QFQ uses a special sendmail notation - this will change in the future.
 - Mail:
 {{!SELECT '' AS sendMailTo, 'Custom subject' AS sendMailSubject, '' AS sendMailFrom, 123 AS sendMailGrId, 456 AS sendMailXId}}
AutoCron will send as many mails as records are selected by the SQL query in field Mail. Field Mail body provides the mail text.
All columns of the SQL are available in STORE_PARENT.
Type: Website
The page specified in URL will be opened.
Optional the output of that page can be logged to a file (take care to have write permissions on that file).
 - Log output to file'='output.log - creates a file in the Typo3 host directory.
 - Log output to file'=/var/log/output.log' - creates a file in /var/log/ directory.
Also overwrite or append can be selected for the output file. In case of append a file rotation should be setup on
OS level.
To check for a successful DB connection, it's a good practice to report a custom token on the T3 page / QFQ record like 'DB Connect: ok'. Such a string can be checked via Pattern to look for on output=/DB Connect: ok/. The pattern needs to be written in PHP PCRE syntax. For a simple search string, just surround them with '/'. If the pattern is found on the page, the job get's 'Ok' - else 'Error - …'.
Access restriction
To protect AutoCron pages not to be triggered accidental or by unprivileged access, access to those page tree might be limited to localhost. Some example Typoscript:
# Access allowed for any logged in user or via 'localhost'
[usergroup = *] || [IP =]
 page.10 < styles.content.get

What You Need to Know About 200 Amp Service Wire
When it comes to electrical systems, one important component to consider is the amp service wire. The amp service wire is responsible for carrying the electrical current from the main power source to the various circuits in your home or building. In this article, we will discuss what you need to know about 200 amp service wire.
A 200 amp service wire is a type of electrical wire that is capable of carrying a maximum current of 200 amps. This wire is typically used in residential and commercial buildings where a higher amount of electrical power is required. It is important to use the correct amp service wire for your electrical system to ensure safety and efficiency.
One important factor to consider when choosing a 200 amp service wire is the material it is made of. The most common materials used for amp service wire are copper and aluminum. Copper is known for its high conductivity and durability, making it an excellent choice for amp service wire. Aluminum, on the other hand, is less expensive but has a lower conductivity compared to copper.
Another important consideration when choosing a 200 amp service wire is the size or gauge of the wire. The size of the wire determines its capacity to carry electrical current. In general, the larger the wire gauge, the higher the ampacity or current-carrying capacity of the wire. It is important to consult with a professional electrician to determine the appropriate size of the 200 amp service wire for your electrical system.
What is 200 Amp Service Wire
200 amp service wire refers to the type of electrical wiring that is used to carry a maximum current of 200 amps. It is commonly used in residential and commercial buildings to provide a higher capacity for electrical power distribution.
The amp, short for ampere, is the unit of electric current. It measures the rate at which electric charge flows through a wire or conductor. A 200 amp service wire is designed to handle a larger amount of current compared to lower amp service wires.
Service wire is the electrical cable that connects the main electrical panel or meter to the utility power source. It is responsible for carrying the electricity from the power source to the building's electrical system. The 200 amp service wire is specifically designed to handle the higher current demands of a 200 amp electrical service.
Using a 200 amp service wire allows for a greater capacity to power electrical appliances, lighting, and other electrical devices in a building. It provides a higher level of electrical service and can support larger electrical loads.
It is important to choose the correct size and type of service wire for a 200 amp electrical service. The wire must be able to handle the maximum current without overheating or causing a fire hazard. It should also be properly insulated to protect against electrical shock.
In addition to the amp rating, service wire is also classified by its voltage rating and insulation type. Common types of service wire include copper and aluminum conductors. Copper is often preferred for its higher conductivity, while aluminum is more cost-effective for longer runs.
|Type||Conductor Material||Insulation Type|
|THHN/THWN||Copper or Aluminum||Thermoplastic|

The first Post Office in South Wellfleet was established in 1829 when Reuben Arey, Jr. was named the first postmaster. Naming a separate post office from Wellfleet's, along with the establishment of the South Wharf and the Second Congregational Church just a few years later, indicated the growth of the South Wellfleet community. The first post office not located in the postmaster's home was William Ward's, starting in 1873, when he opened the office at the railroad depot.
The Deyo History mentions that there may have been very early stores in South Wellfleet: one at Aunt Lydia's tavern; another at Reuben Arey's home where he kept the first South Wellfleet post office; and still another at Daniel Higgins' home, just after the War of 1812. This is the only mention of merchant activity prior to the Cole store described below.
For over 150 years, there has been a store near the head of Blackfish Creek. The first merchant to set up his business there was Collins Smith Cole, who became a respected South Wellfleet citizen over the course of his career, earning the title "Squire Cole". He was born in 1797, the son of Ebenezer and Sarah Cole. Six generations before him was Daniel Cole, an original 1644 settler of Eastham, and part of the group of settlers that sought to expand Plymouth Colony for the next generation.
We know that Collins S. Cole's house — still there, and facing Lecount Hollow Road — was there in 1828, because when the Town voted to spend $30 to build the footbridge over Blackfish Creek that year, the record places the bridge "nearly south of Collins S. Cole's house". The house faced the Old King's Highway, but later, as the County Road became the focus of the community later, it turned its back to the owner's merchant activity.
The Hurd history of Barnstable dates the building of Collins Cole's store to 1844. The building referred to was the two-story frame building pictured here. The door was in the middle with a sign over it and there are two windows on either side of its door. The Deyo History mentions Collins S. Cole first in 1844, when he and Alvin Paine bought the South Wharf and Cole "took the store." We know there was a fire that partially destroyed the South Wharf about that time. While the store was originally at the Wharf to supply the mackerel boats, it appears that either a separate store was developed over at the head of Blackfish Creek or the Wharf store was moved. The record is not clear.
The building of the County Road in 1846 certainly improved the situation for the owner. Now the road came right to the store. One account says you could get whatever you needed there, from a paper of pins to a gallon of molasses. The farmers brought their butter and eggs to sell there.
Collins S. Cole married twice, first to Mary Jenkins Holbrook, whom he married in 1824. Their first son, William Henry Cole, was born in 1825, and was the grandfather of Charles Cole, whose memory book I have been using to document the history of South Wellfleet. A second son, Collins Smith Cole, died as an infant. Mary died in 1828 and is buried in South Wellfleet Cemetery.
In 1831, Collins Cole married Ann Gibbs Hapgood, and, in 1832, they had a daughter, Julia Ann Cole. In 1833, Mr. Cole purchased a pew in the new Second Congregational Church being built in South Wellfleet.
Until he became one of the owners of the South Wharf, Collins Cole was a mariner. After he became a merchant, he also became a Justice of the Peace, according to an 1850 listing which notes both he and Reuben Arey held this title in South Wellfleet. He appears to have funded the sale of a house in South Wellfleet from Reuben Arey to Captain Scotto Foster and Jonathan Doane, a house that still stands today. In the 1850s he gave a mortgage to Captain Foster on his home; perhaps the fishing had been less than optimal that year. Captain Foster named his second son Collins Cole Foster, honoring his neighbor. In 1861, Mr. Cole was listed as a County Commissioner in a news article.
Collins Cole died in 1868 at age 70, and the South Wellfleet Cemetery has an obelisk making his grave, those of his two wives (Ann Cole died in 1882), and his infant son. In Charles Cole's memory piece, he remembers that Collins Cole left his family an estate valued between fifty and sixty thousand dollars.
Initially, the Cole family ran the store. One source indicates that William Cole built a house next door to his father's — that would be today a second historic property on (now) Lecount Hollow Road. But in Charles Cole's memory piece, he notes that his father, William H. Cole, built a carriage house, which his daughter Mary Ann and her husband Isaac R. Paine later converted into a dwelling house. It should be noted that this Isaac Paine is Captain Isaac R. Paine, not the Isaac Paine mentioned below. In 1871, before he turned fifty, William Henry Cole died of typhus that infected the family when Isaac R. Paine brought it back from a trip to the south to "freight oysters." Despite their father's death, the family was well taken care of with the grandfather's legacy.
In 1872, the South Wharf Company took over the Cole store. They built the ell on the south side that became the separate post office. In 1880, they sold it to Alvin Paine, and the sign over the door changed again, and a north ell was added for his grain business. Of course, by this time, there was another building in the "South Wellfleet business center" – the Old Colony Railroad depot.
Alvin Paine was one of the influential South Wellfleet Paines. He was the grandson of Thomas Paine, the Wellfleet family founder who started out in Truro and then came to Wellfleet. Alvin Paine, born in 1837, was married to Eliza, the daughter of Captain Scotto Foster.
He purchased the Reuben Arey, Jr. home from the heirs of Reuben (3) in 1877 – the Areys having moved their lives to many other places off-Cape by that time. For a while longer, however, Oliver Arey kept the first Arey home.
A Barnstable Patriotarticle in 1884 announced that Alvin Paine was "having the grounds graded and sodded in front of his store" and noting that this work would make a great improvement.
Alvin Paine died in 1889 or 1890 and left his store to his son, Isaac Paine (born in 1867) who over his lifetime became known as "Ikey Paine." One of the famous stories about Ikey Paine is that he would not sell the locally bottled Pilgrim Spring beverages because he did not want children to learn to drink out of bottles, perhaps teaching them about drinking liquor!
Another property became a store in the "South Wellfleet Business District". Amos Rideout transferred the "property opposite the Alvin Paine store" to Jeremiah Rich in 1904 and discharged their mortgage in 1907. But when the property was sold to David Buitekan in 1914, it was Mr. Rideout who made the sale. This is what became known as "The Little Store" that appears in several early 20thcentury photographs. Initially, there are horses and wagons in the photos, and later there are gas pumps here. In 1914, Buitekan became the postmaster for South Wellfleet. In a 1916 photograph, the post office sign is hanging above the door.
There's one mystery about the stores that I have not solved. In an undated photograph, pictured here, with the Marconi Towers in the background, there is another building behind the Paine store but I have not figured out what this is. We know at some point the Little Store disappeared, and one person has remembered "another store up the hill". Is this that store?
In 1923, Isaac Paine transferred the General Store to David Buitekan. Ikey Paine lived in South Wellfleet in the Reuben Arey Jr. house until 1943, when he died fighting a fire in his barn.
In a memoir by Holman Spence that appeared in The Cape Codder in the 1970's, he describes life in South Wellfleet when his parents bought land and built a cottage on Indian Neck. By this time, Spence describes the "Little Store' and its old gas Socony pumps as belonging to Emanuel J. Davis, while Buitekan owns the (former Paine) store and runs the post office, with his wife Annie Buitekan.
The Buitekans are in the 1920 Federal census for Wellfleet; Annie is 52 years old, with parents born in Scotland; he is 47 years old, with parents born in Holland. Her maiden name "Ross" appears in one of the deeds; Monroe Ross, presumably her brother, is living with them in 1920.
Holman Spence, in his 1970s' memory piece of South Wellfleet, describes the Little Store as carrying "every need of the whole little community down to items that were called for once in every three or four years. In the glass cases on the counters was everything from rubberized gloves to mousetraps, harness parts, candy, 3-in-1 oil, lamp wicks, shoe laces, Beeman's pills, scythe stones, boat caulking and "Never Leak." The walls were hung with more items; sometimes a customer really had to search for an item, and then left the store in even more disarray.
Spence describes the almost-ceremonial moment of the day

Convertin' a constant force into an oscillatin' one is a useful trick. Ya'll seen em: gravity-powered pendulums and wind-powered turbines for example, them both set machines a-spinin and a-swingin by exploitin' a constant force.
Them machines might work sweetly at macroscopic scales but ain't nobody cracked it on the nanoscale even though nanobods are a-chompin at the bit to reproduce this trick. The trouble is that gravity ain't strong enough at this level and as for wind, who you kiddin?
That leaves only tricky-dicky forces from the dizzy world of electrostatics and magnetics and these are so poorly understood on tiny scales that them nanobods are still a-wondrin and a-ponderin over how to harness them.
But Hyun "Mighty" Kim and his crew at the University of Wisconsin-Madison say they cracked it.
Their device is a kinda nano-mushroom that stands between the plates of a capacitor, in a constant DC field.
Give the mushroom a push and it leans towards the source electrode where electrons tunnel across into the mushroom head. The DC field exerts a force on this extra charge on the 'shroom, pushing it towards the drain electrode where the electrons jump ship. The force disappears and the mushroom's stiffness sends it swinging back to the source again like metronome, and the process starts again.
Voila! A nanomechanical oscillator that converts a a constant force into an oscillation.
Them nanobods are gonna be cockahoop over this one, betcha!

Packaging and High-Temperature Characterization of a 650 V, 150 A eGaN HEMT
In this work, a commercial 650 V, 150 A enchancement mode GaN (eGaN) HEMT from GaN Systems was packaged and characterized for its static properties at temperatures up to 250° C. The eGaN HEMTs studied in this work were purchased from GaN Systems with the part number of GS-065-150-1-D rated at 650 V, 150 A. Copper was the surface finish on all the gate, source, and drain pads, and the backside of the chip was finished with silver.
Fig. 1 is a cross-sectional view of the package design. Silver sintering was used for attaching the device chip on direct-bond-copper substrate, and gold wire-bonding for interconnections. Fig. 2 shows the fabrication process of the high-temperature package.
The packaged device was tested at temperatures up to 250 ° C to determine the effects of temperature on its static characteristics. It survived multiple heating/cooling cycles between room temperature and 250° C as it underwent static testing on a curve tracer. Compared to the characteristics at room temperature, at 250 ° C, the threshold voltage was reduced by about 30%, the saturation current was down below 45% of the rated current, and the leakage current was increased by tens of times.

A creditor is a party (e.g. person, organization, company, or government) that has a claim to the services of a second party. The first party, in general, has provided some property or service to the second party under the assumption (usually enforced by contract) that the second party will return an equivalent property or service. The second party is frequently called a debtor or borrower.
The term creditor is frequently used in the financial world, especially in reference to short term loans, long term bonds, and mortgages. In law, a person who has a money judgment entered in their favor by a court is called a judgement creditor.
The term creditor derives from the notion of credit. In modern America, credit refers to a rating which indicates the likelihood a borrower will pay back his or her loan. In earlier times, credit also referred to reputation or trustworthiness.

At the 24th APS Annual Convention, Iris Mauss will host a workshop called Studying Emotions in the Laboratory. Mauss is an assistant professor of psychology at the University of California, Berkeley. Her own emotion research focuses on emotion regulation and how emotion regulation affects wellbeing. She has given the Observer a preview of what she will cover in her workshop.
What methods for studying emotion are you going to discuss in your workshop?
For inducing emotion, we will discuss advantages and disadvantages of various approaches, including pictures, film clips, and naturalistic interactions. For measuring emotion, we will cover advantages and disadvantages of three common measures: experience, facial behavior, and autonomic physiology. From within this wide range of methods, the workshop will focus on those of particular interest to workshop attendees.
How can researchers measure emotional responses empirically? Can you give an example of the standards you use for your own research?
This is a very complex, big, and tricky question that relates to the larger question of what an emotion is. Briefly, researchers often take a multi-method approach to measure the intensity of participants' emotions. In the workshop, we will focus on three common approaches to doing so: experience sampling (e.g., asking participants how much anger they felt), coding facial behavior (e.g., coding from videotapes the intensity of facial expressions of anger), and measuring autonomic physiology (e.g., measuring participants' blood pressure).
What are some challenges researchers encounter while studying emotion in the lab?
There are two major questions that researchers who want to study emotions in the laboratory are faced with. First, how can scientists ethically make participants emotional (evoke emotions such as sadness, happiness, or anger) in the laboratory? And second, how can scientists measure whether an emotion has occurred and how intense the emotion was? Basically, the whole workshop will deal with how to overcome these challenges, and we will talk about various ways to address these challenges as well as the advantages and disadvantages of each approach.
Why should convention attendees come to your workshop? What can they expect to take away from your presentation?
I think conference attendees who would benefit from this workshop are those who seek a brief and practical introduction to studying emotions in the laboratory. Attendees should emerge from the workshop with the ability to begin to design rigorous laboratory studies involving emotion.
Leave a comment below and continue the conversation.


Finding that one special star
Rehoboth Christian students Southwest stars, find fun in astronomy

TOP: Calvin College astronomy student Rick McWhirler talks with Rehoboth Chirstian Middle School students about the different levels of brightness that could be seen in the data.
SECOND FROM TOP: Astronomy student Hannah Pagel of Calvin College sits with her group of students as they shift through hundreds of star images hoping to find that one variable star.
T he stars don't go unnoticed in the Southwest because it has dark clear skies that people from across the nation have come to admire.
College students from Calvin College in Grand Rapids, Mich. have come to the area for that very reason as part of a course called "Astronomy of the Southwest."
It is through that class that they shared their interest in stars when they presented an astronomy lesson for the middle school science class of Rehoboth Christian School held Monday.
Calvin College Professor Larry Molnar visited the school with his class of 10 students from his astronomy course. Molnar explained that his course allows his students to use the different telescopes.
"This is just a place of beautiful skies, dark and clear," Molnar said adding that this course also allows the students to look at the earth as a planet and gives the opportunity to learn more about the people of the southwest.
Molnar started off the class discussion by explaining to the seventh and eighth grade students of Rehoboth Christian Middle School that they would be talking about "variable stars".
A variable star is a star that can change its brightness, and the brightness of a star can change due to three possible modals, said Molnar.
One possibility is rotation where the dots found on a star affects the stars levels of brightness. Another possibility is when two stars are orbiting around each other, and the third possibility is when a star is pulsating, but each of those possibilities affects the stars brightness level.
"Most stars don't change they just look the same from one day to the next. 999 out of a 1000 stars might do that, but the last star might do something really dramatic and different, get much brighter, get much fainter," Molnar explained. "There are many interesting stars like that that have not been catalogued because people haven't taken the time to sit and watch and wait, but that's something we can do with that small telescope we have."
"We spent the whole night looking at different places in the sky, each with many stars and something interesting might happen. The wonderful thing about real science is you don't know what it's going to be yet," Molnar said. "We're going to show the kids what our students have found and have them look at some stars and see if they can find something of their own."
Molnar split the kids into six groups allowing each of them to look through data collected from the telescope at Rehoboth.
He wanted each of the kids to shift through the variety of stars to see if they could find a variable star.
"One by one the computer is showing them the brightness of an individual star and how it changed through the course of the night. On average nothing changes."
"It was usable for everybody," said Calvin College junior Daniel Van Noord, who created the Fitz Fuller and Data Retrieval System Software used to analyze the stars. "That was part of the reason why I created the software. I am really hoping it instills not only an enjoyment in astronomy but in science in general."
But Molnar said by looking at all the data, there is always a chance that they will find that "one star that does something special."
With luck two groups from the first and second period were able to find that one star, and Molnar said that was amazing.
"I was really happy that the kids found a variable star," Van Noord said because it is not always guaranteed they will find. "Whenever you can get middle school or high school kids excited about science, it is a good thing."
"Science is cool and fun," said Van Noord on what he hopes the students take from their presentation.
"They want to find their own new star," Molnar said about the students of Rehoboth. "I hope they find science is fun and that discovery is fun."
"One of the main things that we try to teach in middle school science is that science is an exploration," said Rehoboth science teacher Chris Huizinga on why he wanted Molnar's class to present their findings to his seventhand eighth-grade classes. "You're trying to find out new information and you're trying to expand your knowledge of the world and the universe around you, this is a great example of students actively doing that."
Huizinga said he hopes his students were able to take away from the presentation that the stuff they are learning in the classroom can be applied to real life scientific searches and discoveries.
"It's not contained to just the science classroom, but it's useable outside. It's something that matters."
Huizinga said the most enjoyable thing about teaching his students about astronomy is that "When they look up at the night sky it's beautiful," and they will be able to appreciate that. "They broaden their view of the night sky."
"I thought it was really interesting learning about all the different kinds of stars out there and the brightness of them. It was really cool," said Brianna Guerrero, 14, student of Rehoboth Christian Middle School. "There are a lot out there and we don't really pay attention to them (stars)."
"I enjoyed the fact that we actually got to look up our own stars and figure out what type of model it was," said Selena Deogado, 13, about the different photos each of the students got to analyze through the software presented.
Added Molnar, "I love just being here because it's beautiful country. I love being here because we get clear skies."

Trouble-free and safe operation
Monitoring and controlling hydraulic pressure and temperature in wind turbine equipment and subsystems is a complex process; at start-up, pressure rises and at shutdown it's released, and for lubrication and rotation functions, maintaining a minimum pressure level is crucial. To ensure smooth and safe operation, the temperatures of the hydraulic unit, generator, drive shaft, gearbox, oil braking and cooling systems have to be accurately monitored and controlled. That's where Danfoss comes in.
Pressure and temperature signals are used by controllers to adjust valves, pumps and other equipment to maintain stable operation and, increasingly, to control safety functions. Designed to handle over-pressure and pressure spikes, liquid cavitations, dirt contamination, intense operating cycles, and extreme temperatures, Danfoss pressure transmitters and temperature sensors have been keeping wind turbines rotating, and safe, for decades.
Two industry favorites are the MBS 3000 pressure transmitter and the MBT 5310 temperature sensor. Fitted with a pulse snubber, the MBS 3000 can withstand water hammer, liquid cavitation and pressure peaks. Designed to handle the heavy vibrations in wind turbines, the MBT 5310 features a spring-loaded sensor to ensure close and reliable contact – furthermore it can withstand temperatures up to 200°C.
If you'd like to hear more about how Danfoss can help getting the best from your monitoring and control equipment, please contact your nearest Danfoss dealer.

Photos: Rare Deep-Sea Angler Fish
National Geographic recently posted photographs of the Chaunacops coloratus, a rare and colorful deep-sea angler, which wasn't discovered alive until 2002 when one was spotted near a seamount off the coast of California. A more recent expedition in 2010 turned up six more of the strange-looking fish.
The fish, which is bright red as an adult, seems to change colors during its lifetime with the adolescents being blue and purple colors. Although it's a strong swimmer, the angler also uses its fins to "walk" along the seafloor for shorter distances.
The angler feeds by using its esca, a dangling piece of flesh, as a lure to fixate curious passers-by, which it then ambushes and eats. Scientists suspect that the angler is also luminescent, although this has not been documented yet.
Take a look at the photographs.


Relationships between explicit and default denials in the Amazon SQS Access Policy Language - Amazon Simple Queue Service
Relationships between explicit and default denials in the Amazon SQS Access Policy Language
If an Amazon SQS policy doesn't directly apply to a request, the request results in a Default-deny. For example, if a user requests permission to use Amazon SQS but the only policy that applies to the user can use DynamoDB, the requests results in a default-deny.
If a condition in a statement isn't met, the request results in a default-deny. If all conditions in a statement are met, the request results in either an Allow or an Explicit-deny based on the value of the Effect element of the policy. Policies don't specify what to do if a condition isn't met, so the default result in this case is a default-deny. For example, you want to prevent requests that come from Antarctica. You write Policy A1 that allows a request only if it doesn't come from Antarctica. The following diagram illustrates the Amazon SQS policy.
 Architectural Overview
If a user sends a request from the U.S., the condition is met (the request isn't from Antarctica), and the request results in an allow. However, if a user sends a request from Antarctica, the condition isn't met and the request defaults to a default-deny. You can change the result to an explicit-deny by writing Policy A2 that explicitly denies a request if it comes from Antarctica. The following diagram illustrates the policy.
 Architectural Overview
If a user sends a request from Antarctica, the condition is met and the request results in an explicit-deny.
The distinction between a default-deny and an explicit-deny is important because an allow can overwrite the former but not the latter. For example, Policy B allows requests if they arrive on June 1, 2010. The following diagram compares combining this policy with Policy A1 and Policy A2.
 Overriding
In Scenario 1, Policy A1 results in a default-deny and Policy B results in an allow because the policy allows requests that come in on June 1, 2010. The allow from Policy B overrides the default-deny from Policy A1, and the request is allowed.
In Scenario 2, Policy B2 results in an explicit-deny and Policy B results in an allow. The explicit-deny from Policy A2 overrides the allow from Policy B, and the request is denied.
