How Long Do Owls Live? (Average Lifespan Data & Facts)
Last Updated on
Barn Owl
Whether you were one of the countless kids waiting for their letter to Hogwarts or just a fan of beautiful birds, owls have fascinated us in many ways over the years. How much do you really know about these winged hunters of the night? For example, how long do owls live?
In this article, we'll learn how long owls usually live as well as some facts about what impacts their lifespan.
owl divider 2What's the Average Lifespan of an Owl?
In the wild, owls live an average of 9-10 years. Some owls live as few as 4 years, however. Owls in captivity tend to live much longer.
Several factors influence how long an owl lives, not just whether they are wild or in captivity. We'll look at a few of those factors next.
Why Do Some Owls Live Longer Than Others?

Nutrition
An owl's diet is primarily made up of small rodents, like mice. They may also eat snakes, rabbits, birds, frogs, and lizards. Owls compete with other predators, including other birds of prey, for their food.
Inadequate food supply is a major threat to owls' well-being and can lead to a shortened lifespan. The owls' prey may be in short supply due to habitat loss, over-hunting by humans, or competition from other predators.
Environment and Conditions
The environment owls inhabit, particularly, the level of contamination from substances like pesticides, plays a major role in how long they live. Owls are sensitive to many environmental toxins, to the point that they may serve as early indicators of a contaminated environment.
Agricultural pesticides have been shown to harm species like the burrowing owl. Many species of owls are at risk of unintentional poisoning from rat and mice bait. Rodent poison typically doesn't kill the rats and mice right away but sickens and slowly kills them.
Like all predators, owls will go for the easy prey when they can and that includes sick and poisoned mice and rats. Rodent bait is so potent it can kill predators as well as prey.
Habitat
Owls live in a variety of different habitats, including forests, deserts, and even suburban areas. Many of them nest in trees, while others use old animal burrows in the ground.
Habitat loss is one of the biggest threats to owls and can lead to premature death, as well as the decline of overall owl populations. Not only are both owls and their prey losing their wilderness homes, but they are coming into closer contact with human populations.
It's illegal to hunt owls but they are still put at risk by illegal hunting. Power lines and cars, as well as domestic pets like cats, are all threats to owls as well.

Size
The size of the owl species is one of the most common predictors of how long they will live. In general, larger owls live significantly longer than small owls. Smaller species, like the Elf Owl, may live for 3-5 years, while one of the largest owls, the Great Horned Owl, has an expected lifespan of about 10 years.
Smaller owls are more likely to fall victim to predators, including other birds of prey, in addition to dealing with the same threats as other owl species.
Sex
Sex doesn't seem to play a major role in the lifespan of an owl. However, it's interesting to note that most of the time, female owls are bigger than males, and a smaller size could work against them.
Genes
Like other human and animal species, owls can suffer genetic conditions that can shorten their lifespan. For example, inherited skeleton and limb deformities have been noted in several owl species, possibly linked to environmental contamination.
As owl populations decline, the genetic diversity present in species may decrease as well. Eventually, this could make the species less adaptable and healthy and lead to shortened lifespans.
Captivity Vs Wild
Owls who live in captivity live significantly longer, sometimes even double, the lifespan of their wild cousins. In captivity, owls don't have to worry about where their meals are coming from and are in no danger from predators–humans or animals. Unlike most wild owls, captive owls also have access to regular vet checkups and medical care.
Healthcare
Unless they suffer some accident, wild owls will probably never see a veterinarian. Wildlife veterinarians are not common due to the extra training involved but having one nearby can play a big role in keeping sick or injured owls alive.
Since regular medical checkups help catch serious problems early, captive owls have an advantage over wild owls. Some wild owls may get sporadic checkups if they are part of a research study or protected population, but most will not.
owl divider 2The 5 Life Stages of an Owl

Egg
Owls generally only lay eggs once a year, with the amount laid varying by species. The eggs will incubate for around 30-37 days, again depending on the species.
Hatchlings
After hatching, owl chicks will stay in their nest for several weeks, entirely dependent on their parents to bring food. Owl chicks are born blind and covered only in down. Their feathers develop while they are in the nest. Both male and female owls help feed the chicks while they're in the nest.
Fledgling
During this stage, the young owls learn how to fly. The age when this occurs varies from 4-10 weeks depending on the species. During this stage, young owls are very vulnerable to predators. Their parents continue to care for and feed them during this stage.
Young Adult
After learning to fly, young owls remain in the care of their parents for a short time before taking off on their own. This may take a few weeks or a few months.

Adult
Adult owls will be on their own until the time comes to find a mate and start their own nest. Owls reach sexual maturity between 1-3 years, depending on their species.
How To Tell An Owl's Age
The type, color, and condition of feathers is the major way that's been studied to tell the age of an owl. Chicks can be aged by which of their adult feathers have developed. You can also look at the amount of white on the underside of some species.
Some owls might be tagged by scientists when they are young, allowing researchers to study them as they grow and keep track of their age at the same time. Owls hatched in captivity can be easily aged based simply on observation and record keeping.

Conclusion
Long considered symbols of wisdom, owls rely on instincts and yes, intelligence to survive in the wild. Wild owls face long odds and unfortunately often fall far short of their expected lifespan because of this. Many dangers that face owls are the result of human behavior. If you want to help the owls in your area live as long as possible, consider building an owl nesting box, avoiding the use of rodent poisons, and learning all you can about other methods to aid in the conservation of owl species.

The Exciting Relationship Between Sea Surface Temperature and Cholera Cases
What is the relationship between sea surface temperature and the incidence of cholera?
a) There is a positive correlation between sea surface temperature and the incidence of cholera.
b) An increase in sea surface temperature causes the incidence of cholera to increase.
c) There is a negative correlation between sea surface temperature and the incidence of cholera.
d) There is no relationship between sea surface temperature and the incidence of cholera.
Answer:
The correct answer is: a) There is a positive correlation between sea surface temperature and the incidence of cholera.
The data suggests an exciting relationship between sea surface temperature and the incidence of cholera. According to the graph, there is a positive correlation between these two variables. As the sea surface temperature increases, the number of cholera cases also tends to increase.
It's essential to understand that correlation does not necessarily imply causation. While the data supports the statement about a positive correlation, it does not prove that an increase in sea surface temperature directly causes more cholera cases. Other factors could be at play, and further research would be needed to establish a causal relationship.
Overall, the data highlights the importance of considering environmental factors, like temperature, in understanding the incidence of diseases such as cholera. By exploring these relationships further, we can improve our understanding of how environmental changes impact public health.

Coimbatore, Sept 6 (PTI) The Tamil Nadu Agricultural University (TNAU) here is making an innovative attempt for mass multiplication of 'elite coconut genotypes' through tissue culture to meet the demand for quality seedlings as well as to reduce the number of nuts going for seed purposes.
The initiative is supported by the Tamil Nadu Innovation Initiative of State Planning Commission and as a first step, the Centre for Plant Molecular Biology and Biotechnology in TNAU has optimised in vitro culturing of dissected embryo and regenerating them into whole plants, the university said on Sunday.
TNAU has brought its tissue culture baby on September 2 on the occasion of the World Coconut Day and planted the first tissue culture derived coconut at its Coconut Garden, a release said here.
The current multiplication ratio of 1:1 enables supply of only 30 per cent of the demand (3 to 3.5 million against 10 million seedlings demand) and the multiplication rate has to be increased to at least 1:20 without compromising on quality and genetic uniformity.
TNAU has brought its tissue culture baby on September 2 on the occasion of the World Coconut Day and planted the first tissue culture derived coconut at TNAU Coconut Garden, it said in a release here.
The demand for coconut has increased by 500 per cent in the last decade and this has widened the gap between supply and demand, the release said adding to meet the increasing demand of coconut and its products, the production and productivity had to be increased.
Establishing elite coconut gardens and rejuvenating the existing aged coconut orchards require quality seedlings elite coconut genotypes, the release said.
Globally, India ranks third in terms of coconut cultivation and production and Tamil Nadu ranks second next to Kerala.
Increased consumption of tender coconuts, increased use of coconut oil for culinary purposes and development of other industrial products from various parts of coconut trees and fruits necessitates significant increase in coconut production.
TNAU is channelising its efforts towards increasing the multiplication ratio up to 1:8 so as to meet the demands of the farmers in the state, the release said. PTI NVM VS VS

Curved Vs Flat Monitors:- Detailed Guide
When curved displays first appeared on the market, most people believed it was just a gimmick and a passing craze that's not worth the excess cost.
So, why exactly do curved paths make more sense than curved TVs, and what are the benefits and disadvantages of curved monitors compared to flat-screen models?
First, we will explain what distinct curvature radius evaluations imply, such as 1000R, 1500R, 3800R, etc..
The lower the number above the'R' isthe steeper the screen curvature will be.
1500R, for instance, refers to a radius of 1500mm or 1.5 meters — in case you were to make a circle out of a bunch of 1500R curved monitors, the radius of that circle could be 1.5m.
In addition, the curvature rating tells you that the optimal viewing distance.
So, with a 2000R curved monitor, you will only get full benefits of the curvature if you're no more than two meters away from the monitor.
Curved Vs Flat monitors
Unlike curved TVs, which usually have subtle curvatures of ~4000R, many curved paths have steeper curvatures of ~1500R. This makes sense as you are going to be sitting farther away from a TV than you would from a monitor.
But the problem with TVs is this to take whole benefit of a curved screen, you also have to be sitting right in front of it, which is not possible to do if you have a great deal of people in the room.
In addition, people seeing the TV in the far sides of a room wouldn't be able to see the entire screen due to the curvature.
So, it's clear why, for most people, a curved TV is not worth the extra price.
There are a few advantages to curved TVs too, which you can learn more about in our curved vs. flat TV article.
These issues do not affect curved monitors since they are meant for a single person sitting in front of the display.
What is more, curved monitors aren't necessarily more expensive than the wellness models. Oftentimes, curved panels are used for budget gaming monitors that are actually less expensive than their flat-panel counterparts.
Of course, how useful is that the curvature on a monitor mainly depends upon the screen's dimensions and curvature radius.
If you were looking to buy the best monitors according to your budget tag please check out our articles on this topic:-
 1. Best Monitor Under 100 USD
 2. Best Monitor Under 150 USD
 3. Best Monitor Under 200 USD
 4. Best Monitor Under 300 USD
 5. Best Monitor Under 500 USD
 6. Best Monitor Under 1000 USD
Small 24″ and 27″ sized curved monitors usually have curvatures of 1500R or even 1800R, which are not even that noticeable due to their small screen size.
With 32″ or bigger curved screens, the curvature becomes more noticeable, especially if it's 1500R or steeper, but then, the curvature isn't exactly necessary.
You shouldn't purchase a 24″ — 32″ widescreen (16:9 aspect ratio) monitor just because it's curved unless you're also interested in additional specifications and features that the screen provides.
Due to the extra width of those monitors, the curvature actually brings the borders of the screen closer to you thus covering of your peripheral vision.
This adds extra depth to the image since you can see more of the display simultaneously, without having to move your eyes/head too much, which improves both eye and immersion relaxation, and also eliminates distortion at the edges of the screen.
Disadvantages Of Curved Monitors
The most important disadvantage of curved monitors is your viewing angles as you won't receive the perfect viewing experience unless you are sitting right facing the display.
So, if you would like to see a movie from your mattress, and your curved screen is not facing it, the picture quality might not be ideal, particularly if the screen has a VA panel with poor viewing angles to the IPS technology.
Obviously, this is based on the monitor's display dimensions and curvature in addition to the particular angle you would be taking a look at the screen.
Still another concern users have with curved monitors is seeing skilled use like design, 2D and 3D modeling, and design, but as long as the curvature is not too intense, it will not be a problem.
In the end, the most important thing to consider is the panel quality itself.
For professional use, you will want to have an IPS panel display for the most precise colors and widest viewing angles, and all widescreen IPS screens are flat-screen.
When it comes to the ultrawide versions, those intended for professional usage have subtle curvatures precisely for this reason; they remove distortion without stretching out the items which are near the borders of the display.
For gambling and multimedia/everyday usage, we highly recommend obtaining a curved monitor if you want an ultrawide display. So far as the widescreen models are concerned, it's just an issue of personal taste.

8.2.12 Object types
Objects are stored in memory just as ordinary records with an extra field: a pointer to the Virtual Method Table (VMT). This field is stored first, and all fields in the object are stored in the order they are declared (with possible alignment of field addresses, unless the object was declared as being packed).
The VMT is initialized by the call to the object's Constructor method. If the new operator was used to call the constructor, the data fields of the object will be stored in heap memory, otherwise they will directly be stored in the data section of the final executable.
If an object doesn't have virtual methods, no pointer to a VMT is inserted.
The memory allocated looks as in table (8.4).
Table 8.4: Object memory layout (32-bit model)

+4 Data. All fields in the order they've been declared.
The Virtual Method Table (VMT) for each object type consists of 2 check fields (containing the size of the data), a pointer to the object's ancestor's VMT (Nil if there is no ancestor), and then the pointers to all virtual methods. The VMT layout is illustrated in table (8.5). The VMT is constructed by the compiler.

african society values little children. africa may be many things, like poor, under developed, exploited by the powerful, exploited by the rich and oppressed by human greed.
but, general african society will not stand for anyone keeping babies or little children (one, two and three years old) in cages.
societies that keep little children in cages, for whatever reason, is not only sick but also disgusting.
little children have nothing. they cannot decide anything for themselves, they are the true innocent. little children are weak and powerless.
a society that places little children in cages is rotten and sick to the core.
a society that traumatises little children does not understand and will not understand many things. such a society is ignorant of brutality. devoid of basic human understanding and also fully capable of perpetrating other extreme horrors.
if a society could cage little children, it is a sick and potentially violent and dangerous society.
an ignorantly violent society is capable of further evolution (or devolution) into even more heinous behaviors. anyone that can actually keep little innocent children in cages does not understand life. is devoid of humanity and has very low emotional intelligence. a society that keeps little children in cages is a very sick society, such societies do not get better, they generally tend to become worse, autocratic and eventually grow to become generally incapable of ethics, morals and humanity.
a society that keeps little children in cages, has stage one cancer.
a society that keeps little children in cages is seriously ill and will in all probability, eventually die.

Economic Importance for Humans: Positive
The role of Ozotoceros bezoarticus in the culture of the Indians was comparable to that played by the bison in the lives of the plains Indians of North America. Later, the pampas deer was hunted commercially for skins for exportation and stomach stones (bezoares) for pseudomedicinal use. Over 2 million skins of Ozotoceros are estimated to have been exported from Argentina in the years 1860-70, and many more were captured in other countries. Official statistics for 1880 indicate that 61,401 skins of pampas deer were shipped from the port of Buenos Aires (Argentina). Also, the pampas deer was hunted locally for food, sport, skins, and stomach stones. Jackson (1987), Nowak (1991).

We discuss in this paper how connections, discovered almost forty years ago, between logics and automata can be used in practice. For such logics expressing regular sets, we have developed tools that allow efficient symbolic reasoning not attainable by theorem proving or symbolic model checking.
We explain how the logic-automaton connection is already exploited in a limited way for the case of Quantified Boolean Logic, where Binary Decision Diagrams act as automata. Next, we indicate how BDD data structures and algorithms can be extended to yield a practical decision procedure for a more general logic, namely WS1S, the Weak Second-order theory of One Successor. Finally, we mention applications of the automaton-logic connection to software engineering and program verification.


How to Help a Ghost Pass Over
How to Help a Ghost Pass Over
May 27, 2021 Ghost Hunting Our Blog 0
In general, ghosts will move on when their purpose is fulfilled. But sometimes a ghost needs specific help to move on and this can be provided by a witch.
There are different ways you can help a ghost pass over: gathering personal objects, performing an Ascension ceremony, or calling in the assistance of an experienced witch.
A witch will perform a ritual to call in the spirit of the ghost. The purpose of the ritual is to draw the spirit back into its body by using personal objects, and then to find out what it wants and needs from you. For example, if the ghost's greatest need is forgiveness, the witch will organize a church service and perform a ceremony while asking God for forgiveness on behalf of the ghost so that it may move on. If no church is available at that time, then a prayer in your home can also be performed in order to ask for forgiveness.
If the ghost needs to pass on more quickly, then a ceremony can be performed to help the ghost ascend. In this ceremony, you will be guided in creating an energy vortex in your home that can help the ghost move on.
The following is one of many ways to perform a ritual to call in the spirit of the ghost. You may also find additional rituals online or create your own based on your need:
1) Find out when the ghost was born and what his/her birth number is (day, month, year). You may search for his or her information through an online genealogy site. For example, and genealogy records are some of the most useful resources to find your family history.
2) Find out about the type of person or animal that this ghost was. For example, if the ghost is a bird, then you will need to find out what type of bird it was so that you can use that knowledge in your ritual.
3) Collect everything from the person's life and store them in a satchel for use during the ceremony. You should have at least one item from each phase of his/her life such as: his/her childhood picture books or toys; toys from ages 1 to 7; high school yearbooks; college yearbooks; graduation gifts etc.. You can also use photos of the person. A satchel is a small cloth bag that will help you to carry all of the objects and pictures.
4) Make a list of images, objects, or any other personal information that the ghost may need to pass over. It could be something as simple as leftover perfumes or toiletries that had been used during life time by the ghost. It could also be a specific object such as a ring, watch, or necklace that was very important to the person during life time.
5) Connect with the ghost on an emotional level and give it your understanding about its purpose in your life.
6) Tell the ghost that you will help it pass over. You may want to include in your ritual a letter of forgiveness from the family for any wrongdoing that took place during life time. Your desire to help also needs to be conveyed to the ghost. Use a pen and paper so that you can personally write down your wishes. Leave the paper where you think the ghost can see it.
7) Decide when and where you will do your ritual. In order for it to be successful, you will need a secluded area with no interruptions or distractions so that no one can hear what is being said during the ceremony or how long it may take.
When you start your ritual, you will need to first find a quiet spot and then you can go about looking for the ghost. Use an object that belonged to the ghost such as a perfume or watch and ask it to come around.
1) Set up an altar with photos of the person or animal that is being called back, any objects that he/she had during life time such as his/her childhood toys, a picture of him/her when he/she was young etc.. If you don't have a picture of the person, use pictures of his favorite movie star or a character from his favorite book.
2) Next, light your candles and incense. The incense is used to help center you and the candles are used to represent the energy that will be focused in your home during the ceremony.
3) Place on the altar other objects such as a rose or a flower that represents love. Give these gifts to the ghost of its lover or family member who have passed on in order to help convince it that you will accept him/her back into your life.
4) Any personal items collected from his/her life can also be placed on the altar such as his favorite stuffed animal or something else that he loved so much during his life time. 5) You can also include a picture of his/her family and friends so that he/she knows that they are still around him. These pictures will help to convince the ghost that he is not alone and that his loved ones miss him.
5) By placing all these items on the altar, you are opening up your heart to the ghost and connecting with it in a way that you want to help it move on to its next journey.
6) In order for this ritual to be successful, you need to stay vigilant during your ceremony. You may want to start off with a short period of meditation where you clear your mind of any other concerns or distractions in order for you focus on the ritual. You can also use written meditation that help to guide the energy to focus solely on the ceremony. After, you can break off for a short period of time to gather your thoughts and then continue with the ritual as shown in the following pictures.
7) Using your sacred objects such as photos, objects and papers, get down on your knees so that you are in a position where you are facing the altar and not anyone else present. Start out by taking a couple of deep breaths in an effort to center yourself.
8) Now that you are in a position to do your ritual, you will want to verbally call out the ghost and ask it to come back into your life.
9) Start off by stating what you want from the ghost.
10) Most importantly, tell him/her that when he/she is finished visiting with you, he must return back to where he came from.
11) Now that you have given the ghost an order, there is no reason to stop, so keep at it until the ritual is complete.

Cotton Balls or Honduran White Bats?
Imagine you were walking along in the Honduran forest and you looked up into a leaf and saw these little white puffballs. You might think "Oh, how nice, I need some cotton balls to swab alcohol on my blisters" and reach up to find that they aren't cotton balls at all but little bats with yellow noses! What tricks the natural world presents to us sometimes! Bats are supposed to be slender, black, scary and sleeping in caves but not these Central American marshmallow puff balls. They prefer to make tent houses underneath broad-leaf flowering plants. They are so very tiny (about 1.5 – 2 inches or 3.7 – 4.7 cm) that the adults look like babies, a hole colony of a dozen or more can be comfortable under those big leaves.

Juno's experimental peer-to-peer launch
Starknet
February 23, 2024
Introduction
As Starknet transitions from relying on the feeder gateway to access the blockchain state to a decentralized network structure, anyone running a node on Starknet will soon become a crucial part of its network!
This shift demands a detailed P2P (peer-to-peer) specification, a feature the Juno team is diving into alongside the teams behind the Pathfinder and Papyrus full nodes. In this blog post, we'll discuss why a peer-to-peer network is important, and provide a step-by-step guide for setting up your own Juno node to join the P2P network.
The P2P feature is currently under active development and being tested on smaller Juno networks, so syncing with non-Juno nodes may be unstable!
How Does a Peer-to-Peer Network Work?
When a new Juno node joins the network, it begins with no blocks, effectively starting at a block height of zero. To update itself, the node first connects with another node in the network, chosen at random, to find out the current highest block number, which could be, for example, 3312. With this information, the new node embarks on syncing blocks from its peers, doing so in chunks of 100 blocks at a time.
This process continues in 100-block increments until the node catches up to the most recent block. For instance, if the node has synced up to block 3300 and the network's current block height is 3345, the node will then sync the last 45 blocks to be fully up-to-date. This method ensures the new node gradually and efficiently synchronizes with the rest of the network, block by block until it reaches the current block height.
Every time the node begins syncing a new set of blocks, it triggers a process that unfolds across five distinct stages. These stages are designed to systematically integrate the blocks into the node's blockchain, ensuring that each block is properly verified and that the node's ledger remains accurate and in sync with the network.
An overview of these five stages is given below.
Juno P2P Sync Process
Stage 1 — Establishing Peer Connections and Requesting Block Components
Stage 1 is where the peer connections are established, and the requests for block information are made.
To aid synchronization, the P2P spec requires the block to be split into five different components so that each piece can be requested from a different peer. The five different block components are block bodies, block headers, transactions, receipts, and events. For each block component, Juno will open a connection stream with a peer, and request that specific block part for the entire range of blocks being queried (e.g., up to 100). For example, the Juno node will ask peer "A" for the events data for the first 100 blocks, and at the same time, ask peer "B" for the block header data for those first 100 blocks, etc.
Each process of requesting a specific block part is shown as a distinct process in Stage 1 of the diagram. These requests are made concurrently, and a given process like the query "Spec Events" can move onto stage 2 before the other block parts have been received from the peers.
Stage 2 — Populating the Intermediate Block Type with Available Block Components
When the Juno node receives the specific block part from a peer, it moves on to Stage 2, which involves populating an intermediate (Spec) Block type with whatever information is currently available. For example, if the event information has been fully received from a peer, then this event data will be used to partially populate the Block type. All other fields like block headers will remain empty at this stage, which is why a separate stage is needed to tie all the block parts together.
Stage 3 — Assembling Block Components
When all the different block parts have been received from peers, they will be pieced together at stage 3. The Juno node will then be ready to convert the entire (Spec) Block into a Juno Block type and perform some sanity checks, which is what stage 4 is responsible for.
Stage 4 — Creating the Juno Block
At stage 4, the Juno node will have all the information required to create the entire Juno block. The block information provided from the process at stage 3 is used to create a Juno block. The Juno database expects the block to be in the correct format to commit it to the database, which is what this process is responsible for. This stage also performs a set of sanity checks on the block, such as verifying the block and transaction hashes.
Note that at this stage in the process, Juno may only have a subset of the 100 blocks it queried, and importantly, it may not have the blocks in the correct order. For example, imagine the node has block 42, but no other block. In this scenario, Juno will be unable to store block 42 because the previous blocks don't exist in its blockchain. Since the blocks need to be stored in order, Juno requires a process to feed blocks into its database in the correct order, which is the responsibility of stage 5.
Stage 5 — Ordering and Committing Blocks to the Blockchain
When the next block is ready to be stored in the blockchain (e.g., we have stored blocks 0–41, and now want to store block 42), this process will take the next block when it's available (e.g., block 42), and perform sanity checks at the blockchain level. For example, block hashes need to be correctly linked together. If these sanity checks are passed, then the stage 5 process passes the latest block onto another process to commit the block to the blockchain. Following this, stage 5 will wait for the next block (e.g., block 43), and repeat the same process.
This process will continue until the Juno node has fully caught up to the head of the blockchain. At any point in this process, the node can serve whatever data it has to its peers.
How Do Nodes Trust Each Other?
For those closely following, a valid question arises: How can new nodes trust the blocks received from their peers? The integrity of the blocks is ensured through a cryptographic verification process. The block data is used to generate a blockhash, and similarly, a hash is also produced from the state-diff. These two commitments are then used to generate a signature for the block.
To validate this signature — and by extension, the block data and state-diff — a node compares it against a public key it receives from the feeder-gateway (a query is made to the feeder-gateway when the node starts). This mechanism ensures that if any block data or state-diff were altered by a malicious node, the resulting commitments and therefore the signatures would differ from the expected values. This cryptographic process effectively safeguards against tampering, ensuring that nodes can confidently trust the blocks they receive and maintain the network's integrity.
Running a Juno P2P Node: A Step-by-Step Guide
Prerequisites and Requirements
We highly recommend using Docker to run a Juno node, which is our only software requirement. Regarding hardware, the minimum requirements are:
 - 2+ CPU Cores
 - 4Gb of RAM
 - 50Gb+ SSD
 - 10 Mbps/sec
Installing Docker
Go to the Docker webpage and select the relevant download option for your system. For example, selecting "Download for Windows" will download an executable file to install Docker on your system, and the same applies for Mac. For Linux-based operating systems, you will also need to select the relevant platform (e.g., Ubuntu). Then, simply open the relevant executable and follow the install instructions.
To verify that Docker has been downloaded, open the Command Prompt / Terminal and run:
docker --version
You should see the version of Docker installed on your system. Note: you may need to open up Docker Desktop on Windows before running this command.
Downloading Juno
With all prerequisites in place, you're now ready to download, install, and run a Juno node. To do this we will first need to download one of Juno's images from Docker hub using the docker pull command. For this tutorial, we will pull the image with Tag 0.10.0
1. Open the command prompt / terminal.
2. Pull the Docker image by executing:
docker pull nethermind/juno:v0.10.0
3. Verify the image has been pulled by executing:
docker images
You should see something like this:
REPOSITORY TAG IMAGE ID CREATED SIZE
nethermind/juno v0.10.0 98bc124d8dbc 13 hours ago 215MB
Running Juno
Now that we have the Docker image downloaded, all we need to do to run a Juno node in p2p mode is execute the following command if using Windows:
docker run -d --name juno_p2p ^
-p 7777:7777 ^
-p 6060:6060 ^
-v %USERPROFILE%/juno_sepolia_p2p:/var/lib/juno ^
nethermind/juno:v0.10.0 ^
--db-path "/var/lib/juno" ^
--network "sepolia" ^
--log-level "debug" ^
--http ^
--http-host "0.0.0.0" ^
--http-port "6060" ^
--p2p

Celebrations started early Sunday afternoon with a parade on Riverside Avenue. Fifty floats participated and even the alumni and Marinette High School bands marched, too. However, that's just the start of the 3rd Annual Logging Festival.
"It's a great family event and this time of the year people are looking for something to do after the 4th, so we're happy that we have this in our town," said Jeff Skorik.
The Logging festival is a way to educate the community about their heritage...how logging, lumbering, and Native Americans built the area.
"Logging is very, very rich in our community. In fact, the island that we're standing on, what used to be a logging community, almost, and the logging mill was right in the place of where our museum is right now," said Judy Alwin, festival chair.
After the parade, festivities continued on Stephenson Island with food music and games. They even had a lumberjack show where they showed the audience how it was done in the old days.
"It's important to keep the history alive because this is how we started. We have a lot of generations in this area, so we're kind of learning about our city as well as our own background," said Bethany Skorik.

NAME
 LockDev - Perl extension to manage device lockfiles
SYNOPSIS
 use LockDev;
 $pid = LockDev::dev_testlock( $device);
 $pid = LockDev::dev_lock( $device);
 $pid = LockDev::dev_relock( $device, $oldpid);
 $pid = LockDev::dev_unlock( $device, $oldpid);
DESCRIPTION
 The LockDev methods act on device locks normally located in /var/lock . The lock is
 acquired creating a pair of files hardlinked between them and named after the device name
 (as mandated by FSSTND) and the device's major and minor numbers (as in SVr4 locks). This
 permits to circumvent a problem using only the FSSTND lock method when the same device
 exists under different names (for convenience or when a device must be accessable by more
 than one group of users).
 The lock file names are typically in the form LCK..ttyS1 and LCK.004.065 , and their
 content is the pid of the process who owns the lock.
METHODS
 $pid = LockDev::dev_testlock( $device);
 This method simply checks if the device is in some way locked and if the owner of the lock
 is still active (otherways it removes the lock). It recognise a valid lock even if only
 one of the two lock files exists (and is owned by an existing process), thus permitting a
 safe use of this library toghether with programs using only FSSTND or SVr4 lock style.
 $pid = LockDev::dev_lock( $device);
 This method first checks if the device is already locked and then tryes to acquire the
 lock building the two lock files. First it creates the file which name contains the major
 and minor numbers (in SVr4 style), then it creates the file with the device name in its
 name. This order reduces the clashes with other processes trying to lock the same device
 (even with a different name) and using this library. It has no problem with processes that
 uses only the FSSTND algorithm.
 $pid = LockDev::dev_relock( $device, $oldpid);
 This method changes the owner of an existing lock; if the pid of the old owner is
 provided, then it checks if the lock was correctly assigned (otherways there is the
 possibility of a process acquiring a lock which was owned by another unrelated process).
 If the device was not locked, locks it.
 $pid = LockDev::dev_unlock( $device, $oldpid);
 This method removes the existing locks on the device. If the pid of the owner of the lock
 is provided, then it check if the locks are assigned to that process, avoiding to remove
 locks assigned to other existing processes.
RETURN VALUES
 All the methods in LockDev library return ZERO on successfull completion of the function
 (LockDev::dev_testlock returns zero if there is no lock on the device), otherways, if the
 device is currently locked by an existing process, they return the pid of the process
 owner of the lock. They return a negative number when some kind of error happens.
 Actually they all return only (-1).

The Stanislaus Regional Water Authority (SRWA) is a Joint Powers Authority (JPA), which includes the California Cities of Ceres and Turlock (Cities). Currently, the Cities rely on groundwater as their only source of drinking water supply. The State of California has identified the Turlock Groundwater Subbasin as a high priority basin under the Sustainable Groundwater Management Act. Reliance on groundwater as a single source of supply is not sustainable and has become less reliable due to both the decline in water quality and the increasing number of regulated contaminants. For this reason, the SRWA has been evaluating water supply options to provide a diversified and sustainable water supply portfolio to the current and future residential and industrial customers in both Cities.
In partnership with Turlock Irrigation District (TID), SRWA has identified the Tuolumne River as a surface water supply that can be used in conjunction with the Cities groundwater systems to provide a long-term, reliable drinking water supply for both Cities. The project to divert, treat and deliver drinking water to the Cities is known as the Regional Surface Water Supply Project (Project). This Project provides a diversified regional water supply, allows for drought water management, improves water quality, and helps to replenish groundwater supplies. The Project is currently in the design and construction phases and is scheduled to be delivering water to the Cities in mid-2023. For the latest information on the Project, click here.
In February 2023 SRWA successfully secured a grant agreement for $5 million through the Proposition 50 Chapter 6C program for Drinking Water Disinfection Projects using UV Technology and Ozone Treatment. The awarded funds do not require a cost share and will be utilized for the Surface Water Supply Project's Ozone Treatment facility portion of the Water Treatment Plant. This grant funding will help offset rate impacts on customers and improve delivered water quality, reduce reliance on groundwater supply and improve water supply reliability and sustainability for all areas served by SRWA.

The VELOMATIC from Schaeffler is an automatic bicycle gearshift system that is suitable for a range of applications. It replaces the conventional manual gearshift system and allows gear hubs in bicycles, pedelecs, and e-bikes to shift gears automatically. The FAG-VELOMATIC automatic transmission is compatible with a wide variety of commonly-used hub gears. It comprises a gearshift actuator and a coupled communications module. The mechanical motion of the bicycle's gearshift system is carried out by the gearshift actuator via a Bowden cable.
The communication module has the function of an information gateway. This intelligent communication allows interaction with almost any conventional electric drive. Thanks to the compact dimensions of its components, it can be installed inside the frame of the bicycle.
The VELOMATIC continuously calculates the optimum gear for the rider based on the bicycle's speed and the incline of the terrain. The gearshift program can be individually adjusted by the rider using the VELODAPTIC bicycle app. The operating software that is installed records the input variables that are needed for regulating the gearshift actuator and derives from them the necessary controlled variables.
- Sensors for uphill and downhill travel
- The system can be integrated into any pedelec with a CAN bus, as it is not dependent on a specific manufacturer
- Automatically switches to the optimum starting gear when the rider comes to a stop based on the incline of the terrain
- Shifting errors are prevented
- Smooth gearshift with no perceptible transition
- Compact and lightweight design
- Extended range for e-bikes due to battery-saving operation
- Premature wear on the bicycle's chain and gearshift system is prevented
- Continuous calculation of the ideal gearshift point using special algorithms
- E-bikes and pedelecs

Many Hauntings of St. George's Cathedral
Many hauntings are associated with the apparitions of St. George's Cathedral, the Grey Lady, the organist, laughing lady ghost and the lost soldier.
St. George's Cathedral, Cape Town, South Africa was built in 1901, the cathedral is said to be haunted by many ghosts. Who exactly the ghost who wears a long, grey robe while walking the cathedral's halls and corridors making strange noises and creating cold spots in the cathedral remains a legend that has persisted over the years and continues to add to the mystique and history of St. George's Cathedral.
Ghostly history of St. George's Cathedral.
One of the most common legends is that the Grey Lady is actually the ghost of Bishop Robert Gray, who served as the first bishop of Cape Town from 1847 until 1872. Some people believe that Gray's spirit still lingers in the cathedral, and that he appears as a grey figure in clerical robes. Gray died in 1872, and he was buried in the grounds of St. George's Cathedral in Cape Town, which he had helped to establish.
The second legend who is said to be the Grey Lady, is Bishop Gray's wife, Sophia, who died in 1871. According to this legend, Sophia's spirit is said to haunt the cathedral, dressed in a long grey dress.
A third legend tells of a bride who was supposed to be married in the cathedral many years ago, but who never arrived. Some people believe that the Grey Lady is the ghost of this bride, who died tragically on her way to the wedding.
The final legend of the Grey Lady of St. George's Cathedral tells of a soldier's wife who died during a siege of the cathedral many years ago. Her husband was away at war, and she was left alone in the cathedral with their child. Some people believe that her spirit still haunts the cathedral, and that she appears as a grey figure holding a child.
St. George's Cathedral in Cape Town, South Africa has several other ghost stories, there is a story of an organist who worked in the cathedral many years ago. It is said that he died while playing the organ and that his ghost can still be heard playing it late at night.
There is also a story of a ghost that is said to haunt the cathedrals Lady Chapel. This ghost is known for its eerie laughter, which can be heard echoing through the chapel.
Yet another ghost story associated with St. George's Cathedral is that of a soldier who is said to haunt the building. According to the story, the soldier died during a battle that took place near the cathedral, and his ghost can still be seen wandering the halls.

Martin-Gutzwiller Fellowship, Award Ceremony
Imaging dynamics: Phase transitions, clusters, and geometry from spectral analysis
The transient, ephemeral and unpredictable are often studied using stochastic dynamics. A central object for such dynamics is the matrix of transition probabilities. Spectral properties of this matrix encode a great deal of information about a system's behavior. I will show how this code can reveal the presence of phase transitions, how it can be used to provide a natural metric on the space (from which clusters and network properties can be obtained) and how, without reference to outside information, it can reveal the geometry of an underlying space for a stochastic process.


Is a Polar Bear a Mammal? – Are Polar Bears Mammals?
Yes polar bear is a mammal. It possesses all the required characteristics of mammals. The ice bear is the carnivorous mammal. It is in fact the most carnivorous of all bear species. Polar bear is also the world's largest carnivorous land mammal living today.
Is a Polar Bear a Mammal?
Like all mammals, polar bear females nurse their cubs with milk. The female possesses mammary glands through which the milk is secreted.
Polar bears possess heart which has four chambers. All mammals have four-chambered heart.
White bears are viviparous in that they give birth to live young instead of laying eggs.
Is a Polar Bear a Marine Mammal?
While polar bear is the largest carnivorous land mammal she is also referred to as the marine mammal because the bear spends more than half of her life in water.
Polar bears have got the amazing ability to swim great distances. They can cover hundreds of kilometers in water without even relaxing. Characteristics such as these make polar bear the marine mammal.
Are Polar Bears Mammals? – Video
Through this blog I am not only going to initiate the debate over polar bears—in fact I'll be looking forward to initiating genuine wisdom and perspective on polar bears. The polarbearfacts.net is a project which is designed to educate just about everyone including teachers, scholars, students, kids, and laymen but, above all, the polar bear lovers!

Suppose I pick $k$ integers without replacement from $\{1, \ldots, n\}$. Let $I$ be the value of the highest integer. A calculation with binomials reveals $$E[I] = \frac{k}{k+1}(n+1)$$ This is a very simple formula - does it have a simple calculation-free proof?

Do you know some instance of calculation-free proof for the expected value of some non-constant random variable? I would like to see it. – Matemáticos Chibchas Feb 7 '13 at 8:22
In many cases, you can use symmetry or some clever conditioning to avoid heavy calculations. – pierre Feb 7 '13 at 8:33
You just said it: "heavy" calculations. This is OK, but no calculations at all? Besides, I agree that conditioning is clever, but it is based on the nontrivial subject of conditional expectation. – Matemáticos Chibchas Feb 7 '13 at 9:04

Picking $k$ integers without replacement from $\{1, \ldots,n\}$ involves breaking the interval $[0,n+1]$ into $k+1$ pieces where the length of each piece has the same distribution.
So the expected length of each piece (including the piece from the highest sampled integer to $n+1$) is $\dfrac{n+1}{k+1}$ and so the expected value of the highest sampled integer is $n+1 - \dfrac{n+1}{k+1}$.
Simple calculation will give your result.
So in general, the expected value of the $j$th sampled integer (counting from the bottom) is $j \dfrac{n+1}{k+1} $.

Sorry by my ignorance, but I don't get it: what is the "same distribution" of each piece? (I don't understand the expected length stuff either, but hopefully this will be cleared when I get illuminated about the "same distribution" issue) Thanks. – Matemáticos Chibchas Feb 7 '13 at 20:08
Very nice! But how do you show that are no "edge effects," i.e., that the length of the first piece has the same as the length of the second? – pierre Feb 7 '13 at 22:04
_USER_ Chibchas: Each length is a random variable with a distribution. Each of these distributions is the same and has the same mean. – Henry Feb 8 '13 at 7:35
_USER_: Imagine seating $k+1$ people round a table with $n+1$ seats: there are no edge effects in the gaps between people. Then cut the table where the first person sits and straighten it into a bench of length $n+1$. – Henry Feb 8 '13 at 7:39
Lovely. Thank you for this fantastic answer. – pierre Feb 8 '13 at 23:41

Click to see full answer.
Considering this, are building blueprints public record?
A blueprint is a map of a building. It ties the concept of design to the details required to erect a structure. Once the blueprints have been filed by the contractor with the municipality building department, these building plans are public records and technically attainable by anyone wanting to view them.
Beside above, how much does it cost to have blueprints drawn up? Blueprints are typically created by a draftsperson using CAD software, with some assistance from an architect. For this example, we'll look at the cost of getting blueprints for a two story, 1000 square foot addition. The average cost is $1200-$1500.
Consequently, is it cheaper to buy or build a house?

Plenty of researchers are anxious to find that suburbia makes us fat, but those of us who grew up running around and climbing trees in big backyards might be more likely to appreciate how certain aspects of suburban living actually encourage healthy living:
- SOUTH Australian children with big backyards are less likely to be overweight and inactive than those with small courtyards, a study has found.
Preliminary data from the Flinders University Achieving a Healthy Home Environment study, which surveyed the homes and lifestyles of 280 southern suburbs families, found the size and set-up of homes contributed largely to how fit and healthy young children were.
Researchers looked at more than 75 physical and nutritional variables in each family home over the past year.
"We found the bigger the backyard, the more active the kids," said Flinders Medical Centre consultant pediatrician Dr Nicola Spurrier, who headed the study that will continue until next year.
"But we also found the amount of play equipment and play areas in a back yard had a big impact too."
Researchers also uncovered other rather obvious points: active parents are more likely to have active kids; healthy kids are more likely to have parents who limit their TV-watching and stick healthy food in the fridge.

Mummy, why does our car smell so funny?
Ever wondered what causes cars to have the distinct "new car smell"?
cause of new car smell - car interior
It is actually the glue, plastics and car mouldings that emit dangerous and unhealthy chemicals to give off this smell. It's like leaving a bottled water to be exposed under the sun for hours. Would you go and drink the water in that bottle? Probably not as the heat causes certain chemicals to be released into the water and these chemicals are harmful to our body.
This is the same for cars.
The new car is built and fully sealed. It is exposed to high heat during the shipping process. As it arrives at the port, it will be parked under the sun and exposed to months of direct sunlight. All this heat will cause Volatile organic compounds (VOCs) vapour to be released inside the sealed car. And that, is how you get your "new car smell".
Cause of new car smell
What about cars that have been used for a while? Some old cars have an old, musty smell that never seems to go away. Ever wondered why?
Mold.
Due to the frequent use of Air-Con and high humidity in Singapore, condensation occurs frequently; promoting mold growth. The Air-con system in your car promotes mold growth with moisture from condensation. And when we on the Air-con, mold is blown into our face via the Air-con vent.
What happens if we inhale mold?
Most adults are perfectly fine when we inhale mold. However, for children with sensitive noses or allergies, this may cause irritation. Furthermore, prolonged inhalation of mold may cause sneezing, runny nose, coughing, wheezing, tearing and redness of the eyes, skin irritation or rash, and asthma. Serious symptoms may include fever and difficulty in breathing and can develop chronic lung disease and infection of the lungs.
Why does my car have bad odor
But my car is brand new, so there won't be any mold.
This problem occurs in both new and old cars. As long as your car Air-con is used, condensation will occur and mold will start to grow. In new cars, the 'musty' mold odour is not as strong not because there is less mold, but due to the presence of stronger chemical odours lingering in the air, hence overpowering the mold odour.
Watch this video to find out more.
Can I get rid of the mold and smell? How?
Japan has developed a new form of Chlorine Dioxide (ClO2) – the buster of SARS, Avian flu, hepatitis, HFMD, pneumonia viruses and other key pandemic viruses – into a daily lifestyle product for health protection.
Ecom ClO2 is the latest revolution of disinfectant that can acidify and decompose the source of bad smell, controlling its production and eliminating odour in the process. It uses the released chlorine dioxide gas to kill germs and viruses in the air or attached to objects, purifying the whole atmosphere.
Can Ecom ClO2 help to prevent the spread of viruses in my car?
As a highly oxidising agent, ClO2 can acidify the mold and bacteria and helps to break down the harmful VOCs in your car. Also, in a small enclosed spaces, it is easy for cross transmission of viruses to occur. For families with children and elderly folks who are more susceptible to viruses, ClO2 can help to lessen virus cross infection between family members.
A Fuss-Free and Affordable way to Disinfect and Deodorize your Car
Your kid recently vomited or soiled himself in your car and the odour still lingers. Your father-in-law just bought some durians and the smell does not seem to go away. How do you get rid of the lingering odour?

modify an existing secret, use UpdateSecret.
 - To create a new version of a secret, use PutSecretValue.
 - To retrieve the encrypted secure string and secure binary values, use GetSecretValue.
 - To retrieve all other details for a secret, use DescribeSecret. This does not include the encrypted secure string and secure binary values.
 - To retrieve the list of secret versions associated with the current secret, use DescribeSecret and examine the SecretVersionsToStages response value.
Link to this function
delete_resource_policy(client, input, options \\ [])
View Source
Deletes the resource-based permission policy attached to the secret.
Minimum permissions
To run this command, you must have the following permissions:
 - secretsmanager:DeleteResourcePolicy
 - To attach a resource policy to a secret, use PutResourcePolicy.
 - To retrieve the current resource-based policy attached to a secret, use GetResourcePolicy.
 - To list all of the currently available secrets, use ListSecrets.
Link to this function
delete_secret(client, input, options \\ [])
View Source
Deletes an entire secret and all of the versions.
You can optionally include a recovery window during which you can restore the secret. If you don't specify a recovery window value, the operation defaults to 30 days. Secrets Manager attaches a DeletionDate stamp to the secret that specifies the end of the recovery window. At the end of the recovery window, Secrets Manager deletes the secret permanently.
At any time before recovery window ends, you can use RestoreSecret to remove the DeletionDate and cancel the deletion of the secret.
You cannot access the encrypted secret information in any secret scheduled for deletion. If you need to access that information, you must cancel the deletion with RestoreSecret and then retrieve the information.
There is no explicit operation to delete a version of a secret. Instead, remove all staging labels from the VersionStage field of a version. That marks the version as deprecated and allows Secrets Manager to delete it as needed. Versions without any staging labels do not show up in ListSecretVersionIds unless you specify IncludeDeprecated.
The permanent secret deletion at the end of the waiting period is performed as a background task with low priority. There is no guarantee of a specific time after the recovery window for the actual delete operation to occur.
Minimum permissions
To run this command, you must have the following permissions:
 - secretsmanager:DeleteSecret
 - To create a secret, use CreateSecret.
 - To cancel deletion of a version of a secret before the recovery window has expired, use RestoreSecret.
Link to this function
describe_secret(client, input, options \\ [])
View Source
Retrieves the details of a secret.
It does not include the encrypted fields. Secrets Manager only returns fields populated with a value in the response.
Minimum permissions
To run this command, you must have the following permissions:
 - secretsmanager:DescribeSecret
 - To create a secret, use CreateSecret.
 - To modify a secret, use UpdateSecret.
 - To retrieve the encrypted secret information in a version of the secret, use GetSecretValue.
 - To list all of the secrets in the AWS account, use ListSecrets.
Link to this function
get_random_password(client, input, options \\ [])
View Source
Generates a random password of the specified complexity.
This operation is intended for use in the Lambda rotation function. Per best practice, we recommend that you specify the maximum length and include every character type that the system you are generating a password for can support.
Minimum permissions
To run this command, you must have the following permissions:
 - secretsmanager:GetRandomPassword
Link to this function
get_resource_policy(client, input, options \\ [])
View Source
Retrieves the JSON text of the resource-based policy document attached to the specified secret.
The JSON request string input and response output displays formatted code with white space and line breaks for better readability. Submit your input as a single line JSON string.
Minimum permissions
To run this command, you must have the following permissions:
 - secretsmanager:GetResourcePolicy
 - To attach a resource policy to a secret, use PutResourcePolicy.
 - To delete the resource-based policy attached to a secret, use DeleteResourcePolicy.
 - To list all of the currently available secrets, use ListSecrets.
Link to this function
get_secret_value(client, input, options \\ [])
View Source
Retrieves the contents of the encrypted fields SecretString or SecretBinary from the specified version of a secret, whichever contains content.
Minimum permissions
To run this command, you must have the following permissions:
 - secretsmanager:GetSecretValue
 - kms:Decrypt - required only if you use a customer-managed AWS KMS key to encrypt the secret. You do not need this permission to use the account's default AWS managed CMK for Secrets Manager.
 - To create a new version of the secret with different encrypted information, use PutSecretValue.
 - To retrieve the non-encrypted details for the secret, use DescribeSecret.
Link to this function
list_secret_version_ids(client, input, options \\ [])
View Source
Lists all of the versions attached to the specified secret.
The output does not include the SecretString or SecretBinary fields. By default, the list includes only versions that have at least one staging label in VersionStage attached.
Always check the NextToken response parameter when calling any of the List* operations. These operations can occasionally return an empty or shorter than expected list of results even when there more results become available. When this happens, the NextToken response parameter contains a value to pass to the next call to the same API to request the next part of the list.
Minimum permissions
To run this command, you must have the following permissions:
 - secretsmanager:ListSecretVersionIds
 - To list the secrets in an account, use ListSecrets.
Link to this function
list_secrets(client, input, options \\ [])
View Source

Attaches the contents of the specified resource-based permission policy to a secret.
A resource-based policy is optional. Alternatively, you can use IAM identity-based policies that specify the secret's Amazon Resource Name (ARN) in the policy statement's Resources element. You can also use a combination of both identity-based and resource-based policies. The affected users and roles receive the permissions that are permitted by all of the relevant policies. For more information, see Using Resource-Based Policies for AWS Secrets Manager. For the complete description of the AWS policy syntax and grammar, see IAM JSON Policy Reference in the IAM User Guide.
Minimum permissions
To run this command, you must have the following permissions:
 - secretsmanager:PutResourcePolicy
 - To retrieve the resource policy attached to a secret, use GetResourcePolicy.

 - To list all of the currently available secrets, use ListSecrets.
Link to this function
put_secret_value(client, input, options \\ [])
View Source
Stores a new encrypted secret value in the specified secret.
To do this, the operation creates a new version and attaches it to the secret. The version can contain a new SecretString value or a new SecretBinary value. You can also specify the staging labels that are initially attached to the new version.
The Secrets Manager console uses only the SecretString field. To add binary data to a secret with the SecretBinary field you must use the AWS CLI or one of the AWS SDKs.
 - If this operation creates the first version for the secret then Secrets Manager automatically attaches the staging label AWSCURRENT to the new version.
 - If you do not specify a value for VersionStages then Secrets Manager automatically moves the staging label AWSCURRENT to this new version.
 - If this operation moves the staging label AWSCURRE

American Academy of Arts and SciencesArticle Free Pass
American Academy of Arts and Sciences, honorary society incorporated on May 4, 1780, in Boston, Mass., U.S., for the purpose of cultivating "every art and science." Its membership—some 3,300 fellows in the United States and about 550 foreign honorary fellows (all scholars and national leaders)—is divided into four classes: the physical sciences, the biological sciences, the social arts and sciences, and the humanities and fine arts. Offices are in Cambridge, Mass.
The society was established in 1779 by a group of Harvard College graduates—including John Adams, Samuel Adams, John Hancock, and James Bowdoin—and incorporated in 1780. It evolved largely as a rival to the earlier American Philosophical Society established in Philadelphia in 1743 but ultimately became the larger society, claiming to represent the United States nationally. Its publications include the Bulletin (eight times a year) and Daedalus (quarterly). The academy holds a convention each May in Cambridge, conducts various other conferences and seminars, and presents the Emerson-Thoreau Medal, the Amory Prize, the Rumford Premium, the Talcott Parsons Prize, and the American Academy Award for Humanistic Studies.

XCMSDB(1) XCMSDB(1)
 xcmsdb - Device Color Characterization utility for X Color Management
 xcmsdb [ -query ] [ -remove ] [ -format 32|16|8 ] [ filename ]
 xcmsdb is used to load, query, or remove Device Color Characterization
 data stored in properties on the root window of the screen as specified
 in section 7, Device Color Characterization, of the ICCCM. Device
 Color Characterization data (also called the Device Profile) is an
 integral part of Xlib's X Color Management System (Xcms), necessary for
 proper conversion of color specification between device-independent and
 device-dependent forms. Xcms uses 3x3 matrices stored in the
 XDCCC_LINEAR_RGB_MATRICES property to convert color specifications
 between CIEXYZ and RGB Intensity (XcmsRGBi, also referred to as linear
 RGB). Xcms then uses display gamma information stored in the
 XDCCC_LINEAR_RGB_CORRECTION property to convert color specifications
 between RGBi and RGB device (XcmsRGB, also referred to as device RGB).
 Note that Xcms allows clients to register function sets in addition to
 its built-in function set for CRT color monitors. Additional function
 sets may store their device profile information in other properties in
 function set specific format. This utility is unaware of these nonstandard properties.
 The ASCII readable contents of filename (or the standard input if no
 input file is given) are appropriately transformed for storage in properties, provided the -query or -remove options are not specified.
 xcmsdb program accepts the following options:
 -query This option attempts to read the XDCCC properties off the
 screen's root window. If successful, it transforms the data
 into a more readable format, then sends the data to standard
 -remove This option attempts to remove the XDCCC properties on the
 screen's root window.
 -format 32|16|8
 Specifies the property format (32, 16, or 8 bits per entry) for
 the XDCCC_LINEAR_RGB_CORRECTION property. Precision of encoded
 floating point values increases with the increase in bits per
 entry. The default is 32 bits per entry.
