Multithreading is attractive in that it can tolerate latency and synchronization by effectively overlapping communication with computation. While several compiler techniques have been developed to produce multithreaded codes from functional language programs, it is very difficult to find effective loop implementation for multithreaded computation. In this paper, we will suggest a loop unfolding scheme, KU-Loop. In this scheme, parallel loops can be implemented more efficiently than sequential loops by effectively overlapping loop-setup with loop execution. In addition, we suggest equations to statically approximate the optimal loop unfolding degree for each loop class using profile information. Finally, we will analyze our loop unfolding scheme by means of simulation over several benchmarks and compare simulation results with the results of the equations.
Keywords: multithreading, loop unfolding, loop unfolding degree, synchronization, communication

Highest concentration of Eocene whales
- Wadi Al-Hitan
- 20015 hectare(s)
Wadi Al-Hitan (Valley of the Whales), is a protected area of some 20,015 ha in the Western Desert of Egypt. Fossil whales were first discovered here in 1905 and, since then, some 379 have been discovered, dating from the Eocene period, 56 to 34 million years ago. These whales cover an evolutionary period of 4 million years, from when the valley was beneath the Tethys Sea. Many of these fossils reveal that, during this period, ancient whales were in the process of losing their hind limbs, and making the final transition from land-based to purely sea-based creatures.

Ἀνδρεία, Τόλμα, Θράσος - Male and Female Courage in Classical Greek Literature
Sammanfattning: This thesis discusses the differences in the descriptions of and the attitudes towards female courage in the literature of the Classical period. Male authors of this period wrote extensively of the martial and virtuous courage of men, andreíā, yet in some instances instead labelled courage as tólma or thrásos. Tólma and thrásos are even more commonly used in descriptions of female courage, audacity or rashness. How these three words could be used in relation to men and women is discussed, and the fundamental belief of the Classical period that women were not capable of courage is encountered. As courage was outside the nature, phúsis, of a woman, her actions were always more likely to be viewed as tólma or thrásos. To what extent the literature of the period can reflect the lived experience of the ancient Athenian is unknown. However, it is concluded that literary works both impact and are impacted by social and cultural values, such as the view that women should not or could not be courageous.

What's with the enclosed water filling stations?
Have you ever wondered why water stations on the South Rim are caged in?
In August 2023, construction crews installed new water filling stations with wildlife resistant enclosures at the Bright Angel and South Kaibab Trailheads funded by Grand Canyon Conservancy. This was completed with funding through a grant from National Park Foundation and Tupperware. The filling stations had been closed because elk had learned to turn on the water and there were too many encounters with humans. The new water filling stations are wildlife proof.

International Albinism Awareness DayUnity In Diversity!
June 13th is International Albinism Awareness Day; a day set aside to raise awareness of the struggles that people with albinism face daily. Albinism is a genetic disorder that results in a lack of pigment in the skin, hair, and eyes. This can make people with albinism susceptible to sunburns and eye problems. While there is no cure for albinism, there are ways to help people with this disorder live their best life. Raising a child is stressful enough, but when your child has a special need, it might feel like you're on your own. We'd want to use this time to express our gratitude to all of the parents who are raising children with albinism. On International Albinism Awareness Day, take some time to learn more about this condition and how you can support those who live with it.
Seven reasons why celebrating International Albinism Awareness Day is a must!
1. To show solidarity with the albinism community
When you offer your support for International Albinism Awareness Day, you send a message of solidarity to people with albinism worldwide. This year's theme is "Made To Shine," with the goal of celebrating the accomplishments and successes of persons with albinism all across the world. It's also a call to stand with people who have albinism as they face their problems. This day is an essential reminder that we are all in this together. By raising awareness about albinism, we can help break down the existing barriers for people with this condition.
2. To educate others about albinism
Many people are not familiar with albinism and what it entails. International Albinism Awareness Day is a great opportunity to educate others about this condition. When you raise awareness about albinism, you can help dispel myths and misconceptions about this condition. Educating others can help create a more inclusive and understanding world for people with albinism.
3. To celebrate the beauty of people with albinism
People with albinism are often marginalised and discriminated against because of their appearance. International Albinism Awareness Day is a chance to celebrate the beauty of people with albinism and to show that they are just like everyone else, deserving of respect and inclusion.
4. To Stand up against discrimination
People with albinism face discrimination and violence in many parts of the world. International Albinism Awareness Day is a chance to stand up against this discrimination and call for an end to violence against people with albinism. It is also a chance to celebrate the strength and resilience of people with albinism who have faced these challenges and continue to fight for their rights.
5. For Respect and Inclusion
International Albinism Awareness Day is a chance to call for respect and inclusion for all people with albinism. It is also a chance to celebrate the beauty and diversity of people with albinism. People with albinism often suffer from discrimination and exclusion. They are often treated as if they are not human and this is wrong. International Albinism Awareness Day is a chance for us to stand up against this discrimination and call for an end to violence against people with albinism.
6. What is the significance of the day?
The significance of International Albinism Awareness Day is to raise awareness about albinism and end discrimination and violence that people with albinism face in their daily lives. It is also a chance to celebrate the beauty and diversity of people with albinism. On this day, let us stand up for the rights of people with albinism and pledge to end discrimination and violence against them. Let us also celebrate their beauty and diversity.
7. To teach everyone there in unity in diversity.
The International Albinism Awareness Day is to raise awareness about albinism and to end discrimination and violence against people with albinism.
Why does albinism happen?
Albinism is a congenital condition in which the skin, hair, and eyes are completely or partially devoid of pigment. Albinism is caused by a mutation in one of several genes involved in the generation or distribution of melanin, a brown-black pigment generated by melanocytes, a kind of cell. Melanin is the pigment that gives skin, hair, and eyes their colour.
Genetic factors determine the amount and distribution of melanin produced by the melanocytes. When one of the genes involved in melanin production or distribution is mutated, it can lead to albinism.
What are the different types of albinism?
There are four main types of albinism, each associated with mutations in different genes:
Oculocutaneous albinism type 1 (OCA1): is caused by a mutation in the tyrosinase gene.
Oculo cutaneous albinism type 2 (OCA2): is caused by a mutation in the P gene.
Oculocutaneous albinism type 3 (OCA3): is caused by a mutation in the TYRP1 gene.
Ocular albinism (OA): caused by a mutation in the GPR143 gene.
What are the symptoms of albinism?
The most common symptom of albinism is reducing pigmentation in skin, hair and eyes. This can result in pale skin and hair, and light-coloured eyes. Other symptoms may include:
People with albinism often have vision problems due to the lack of eye pigment. Although persons with ocular albinism lose their central vision, they nevertheless have good side vision. This can cause reduced visual acuity and sensitivity to bright light.
People with albinism are at increased risk for skin cancer. They may also have other skin problems, such as sunburn, rashes and dryness.
Some types of albinism are associated with hearing loss.
June 13th is International Albinism Awareness Day. It can be difficult enough to raise a child, but when your child has a particular need, it can feel like you are doing it all alone. We want to take this opportunity to thank all of the parents out there who are caring for children with albinism. You are amazing! If you are looking for support, please reach out to one of the other organisations dedicated to helping families affected by albinism or us. Together, we can make a difference in the lives of these beautiful children.

A measurement of head-related transfer functions (HRTFs) with high spatial resolution was carried out in this study. HRTF measurement is difficult in the proximal region because of the lack of an appropriate acoustic point source. In this paper, a modified spark gap was used as the acoustic sound source. Our evaluation experiments showed that the spark gap was more like an acoustic point source than others previously used from the viewpoints of frequency response, directivity, power attenuation, and stability. Using this spark gap, high spatial resolution HRTFs were measured at 6344 spatial points, with distances from 20 to 160 cm, elevations from -40deg to 90deg, and azimuths from 0deg to 360deg. Based on these measurements, an HRTF database was obtained and its reliability was confirmed by both objective and subjective evaluations.

Using your hat:
- To remove the bobble, grasp the hat as close to the magnet as possible with one hand and the bobble with the other and snap (as if you were breaking a KitKat). This way you avoid pulling on the hat and the seams.
- To store the hat and its three bobbles in the box, remove the bobble from the hat, put the bobbles in the hat, roll it widthways and put it in the box.
- Some hats (meads) have a "loose" effect - they are designed to fall backwards so feel free to pull them back a little to put them on.
- Our materials are tested for pilling, however, like with any fabric it happens after a while. To delay this, avoid carrying your hat in the bottom of a bag or in a place where it could rub and turn it over if it does.
Caring for your hat:
- Wash at 30 °C or 40 °C without the bobbles! It's more environmentally friendly and it works very well. The bobbles don't go through the wash because there is a small spot of glue to hold the threads together.
- Air-dry flat, avoid tumble drying clothes, it's not very environmentally friendly and it will damage your super hat.
- Clean the bobbles with a damp cloth, do not machine wash.

UNlisted's Andre Fraser: How does sound relate to color, heat?
(Associated Press )
The Republican Lifestyle Desk By The Republican Lifestyle Desk The Republican

The hotter a flame is, the farther along the color spectrum it is.
Springfield High School of Science and Technology
You are watching "MinutePhysics" of Vsauce on the YouTube app on your phone at 11 p.m., unable to go to sleep. You click on a rather long video of the sound of an astrological body in the universe, lowered by x^10 octaves. You close your eyes, and you find that you can see a white-blue light. You wrap yourself tighter in your sheets. Despite it being 95 degrees, you feel cold.
So what does it mean? What does the sound of heat look like?
andrefraser.jpgAndre Fraser
According to that physics teacher we all had in school, everything functions at specific wavelengths. Hitting a standard fork tuned to A will provide a note at 440 Hz, or A4. Boiling water in a pot will cause the molecules to speed up. Colors of light vibrate at a frequency with the infrared-ultraviolet spectrum.
Is it possible for sound, heat, and color to be related in any way?
If you take a cube of ice 10 cubic centimeters, and put it in a pot over a flame, it melts. It melts because the bond keeping the molecules of the ice together isn't strong enough for the energies provided by the molecules, and the molecules that were once vibrating slowly next to each other are able to vibrate at a faster speed.
Although, why are we still calling it speed. Things vibrate at frequencies. Continue heating the water even more, the molecules are loose enough to become gaseous and evaporate into the air.
So then why is orange considered a warmer color than blue? Is it because orange reminds us of warm days full of sunshine, and blue reminds us of the cool water we drink during that day?
Perhaps, but colors react quite the opposite to heat. If you strike a match and touch the red flame, you would feel it sting for a while, but not for too long.
Meanwhile, if you lit a Bunsen burner and touched the blue flame, you would certainly feel pain for a much longer time than the match inflicted.
Why? Blue flames are hotter than red flames, obviously. The hotter a flame is, the farther along the color spectrum it is, starting from red and advancing to blue, and eventually white.
But what does that mean about hearing colors or seeing sounds? Is it possible that hearing sounds, with lower frequencies, can also lead to seeing colors of proportionally lower frequencies?
Does our brain amplify sounds by about 10 trillion, and prospectively force us to perceive the sight of a relative color in the void of vision? Does it work the other way? Is the ringing in our ear our brain slowing down the frequency of the blue on the wall we have been staring intently at for the past hour? Is that what musicians refer to when they describe the music rather colorfully?
Can science ever find a relationship between sound, heat, and visible light/colors? Perhaps one day. For today, though, all we can do is just wonder. Perhaps one of you young scientists reading this will be inspired to find an answer.

Generate an id for imported data (Excel)
Post by leven.steve »
I was hoping that importing data would auto-generate/increment the ID column but it doesn't (unless I'm mistaken?)
So I wrote this function in Excel VBA to generate a random string for the "id".
Usage: (in Excel column)
Function MakeApperyID(length As Integer) As String
' create a id string of "length" chars using 0-9 and a-f only
' in keeping with Appery DB _id format you could call this
' with length 4 to create a starting 4 char sequence in a fixed cell location
' and then add that to a length 20 call to create the remainder of the ID
Code: Select all
 Dim Result
 Dim i, j, k
 Dim ch
 Randomize (Now)
 Result = ""
 For i = 1 To length
 k = CInt(Rnd()) 'zero or one to decide on letter or number
 If k = 0 Then
 j = CInt(Rnd() * 5)
 ch = Chr(j + 97)
 j = CInt(Rnd() * 9)
 ch = Chr(j + 48)
 End If
 Result = Result + ch
 MakeApperyID = Result
End Function
Feel free to use, amend and feedback any useful changes.

Alkali and alkaline earth metallic (AAEM) species (Na, Mg and Ca) exist in Victorian brown coal mainly as carboxylates forming a part of the coal organic matter or as dissolved salt (NaCl) in the coal moisture. The experimental results in this paper show that the chemical and/or physical form of sodium in the brown coal is an important factor influencing the volatilisation of sodium during pyrolysis. Significant amounts of light species containing carboxyl or carboxylate groups such as formate, acetate and oxalate were found in the volatiles from the pyrolysis of the brown coal. It is believed that the release of AAEM carboxylates is an important mechanism for the volatilisation of AAEM species, particularly at low temperatures (<600°C). The carrier gas flow rate passing through the coal bed can greatly affect the volatilisation of AAEM species through this mechanism. Another mechanism for the volatilisation of AAEM species is the breakage of bonds between AAEM species and char matrix at high temperatures. Under our experimental conditions, the sodium in the form of NaCl in the coal substrate seems to volatilise more easily than the sodium in the form of carboxylate in the coal substrate. The monovalent species (Na) is volatilised much more easily that the divalent species (Mg and Ca) during pyrolysis.

container is named development. It is assumed that this network has already been created prior to using the included Docker Compose file. The reason for this is to avoid generating a default network so that other Docker containers can access the GitLab CE instance (e.g. Jenkins for CICD, etc.) using the Docker embedded DNS server.
If no network has been created, run the following Docker command (geared toward Linux): sudo docker network create network-name. Be sure to replace network-name with the name of the desired network. For more information on this command, go here.
Port Mapping
The external ports used to map to the internal ports that GitLab CE uses are 9150 (maps to 443 for HTTPS) and 9151 (maps to 22 for SSH). These ports can certainly be changed but please be mindful of the effects. Changing the port mapped to HTTPS will require changing it on the external_url setting found in the Docker Compose file.
However, if the external port for HTTPS is set to the same port used internally (e.g. 443), then the port can be omitted from the external_url setting and the nginx['listen_port'] setting can be omitted as it will no longer be required.
Data Volumes
It is possible to change the data volume folders mapped to the container to something other than volume_data/x if desired. It is recommended to choose a naming scheme that is easy to recognize.
Configuring Git to Work with a Self-Signed Certificate
For Git to work with a self-signed certificate, a few configuration options need to be specified. There are two ways to do this explained here and one may be better suited to the given situation than the other. Read through the options and pick the best one for the given circumstances.
Option 1 – Modify the Global Git Configuration
To configure Git to always use the self-signed certificate for all HTTPS transactions, modify the Git configuration (global .gitconfig file) and add the following (geared toward Windows). This file is usually found at C:\Users\jsmith\.gitconfig and be sure to replace the user folder jsmith with the correct one suited to the given context.
This assumes the certificate has been copied into a different directory (e.g. c:\Users\jsmith\certificates) and then referenced in the global Git configuration file. This directory can be changed to something else if desired.
Option 2 – Specify the Self-Signed Certificate Upon Git Clone Operation
This option, while being more manual in nature, specifies the self-signed certificate to use when performing a Git Clone operation. Once the repository has been cloned, additional transactions made against it will use this certificate. One benefit to this approach is having the ability to interact with other repositories that do not use a self-signed certificate (e.g. public GitHub repos). For most people, this will be the best option.
Run the following command to clone a repository and specify the self-signed certificate to use for it (geared toward Windows):
git clone -c http.sslCAPath="C:\\Users\\jsmith\\certificates\\gitlab" -c http.sslCAInfo="C:\\Users\\jsmith\\certificates\\gitlab\\server.crt" -c http.sslVerify=1 _URL_
Please see Option 1 above for more details on the path used with this command. This path will be different depending upon the context.
Further Reading
For information making this change on platforms other than Windows or for extra details, please go here.
Conclusion
Getting GitLab CE working with HTTPS using a self-signed certificate isn't always a straight forward process. Certainly there are a few examples that exist in the wild but I could never find anything that worked perfectly for me. This is why I created my own and shared it with the world. My hope is you find this useful for your current needs. Feel free to ask any questions or submit pull requests to improve what I've shared and good luck with your future endeavors.

Suppose $X$ and $Y$ are Banach spaces whose dual spaces are isometrically isomorphic. It is certainly true that $X$ and $Y$ need not be isometrically isomorphic, but must it be true that there is a continuous (not necessarily isometric) isomorphism of $X$ onto $Y$?

Indeed, $\ell_1$ provides a strong counterexample. As noted by Matt, the spaces C(X), where X is countable and compact, provide nonisomorphic Banach spaces whose duals are isomorphic to $\ell_1$. If X is countable and compact (and Hausdorff, of course!) then X is homeomorphic to a closed ordinal interval [0, a] (equipped with its natural order topology) for some countable ordinal a; this result is known as the Mazurkiewicz-Sierpinski theorem. About 50 years ago Bessaga and Pelczynski showed that if a and b are infinite countable ordinals and a < b, then C([0, a]) is isomorphic to C([0, b]) if and only if b < a^*w*, where w denotes the first infinite ordinal. Thus C([0, w]) is in fact isomorphic to C([0, w^2]), contrary to Gerald's assertion above. Moreover, the least infinite ordinal b such that C([0, b]) is not isomorphic to C([0, w]) is b = w^w. Combining the Mazurkiewicz-Sierpinski result with the Bessaga=Pelczynski result, one has that each space C(X), where X is countable and compact, is isomorphic to C([0, w^(w^*a*)]) for a unique countable ordinal a. In particular, there are uncountably many nonisomorphic Banach spaces whose duals are isometrically isomorphic to $\ell_1$, namely the spaces C([0, w^(w^*a*)]), where a varies over the set of countable ordinals.
$\ell_1$ has other preduals too. For example, a 1972 paper from the Israel Journal of Mathematics by Yoav Benyamini and Joram Lindenstrauss exhibits a Banach space E whose dual is isometrically isomorphic to $\ell_1$, but E is not isomorphic to any space of the form C(X).
Although Gerald's assertion that the Cantor-Bendixson rank distinguishes between spaces of continuous functions on countable compact spaces is not correct, there is a rank/index that does distinguish between the isomorphism classes of these spaces, namely the Szlenk index. In fact the Szlenk index may be used to prove the 'only if' direction of the Bessaga-Pelczysnki result.
I strongly recommend Chapter 2 of the book Biorthogonal Systems in Banach Spaces by Hajek et al if you want to read about the Szlenk index and a proof of the Bessaga-Pelczynski result. That book also contains a sketch proof of the Mazurkiewicz-Sierpinski theorem; for a full account of that theorem I recommend Section 8 of Semadeni's classic book Banach spaces of continuous functions.
If you want a different example, I think the James-tree space JT would do. JT is separable but its dual is (at least I think so - it is worth checking!) isometrically isomorphic to the dual of the direct sum $*JT \oplus H*$, where H is Hilbert space of dimension equal to the cardinality of the continuum. In particular, $*JT \oplus H*$ cannot be isomorphic to JT because they have different density characters, but their duals are isometrically isomorphic. If you want to check the details of this example consult Chapter 13 of the Albiac and Kalton book recommended above by Matthew.

If X is any countable, compact topological space, then consider the Banach space C(X). The dual space is the finite measures on X, but as any measure is countably additive, and X is countable, taking some ordering we get an isometric isomorphism between C(X)* and $\ell_1$. But not all such C(X) are isomorphic: you can find such X by taking a countable ordinal w and considering the closed interval [0,w]. This is all very nicely explained in the book "Topics in Banach Space Theory" by Albiac and Kalton.

One may also remark that $c_{0}$ $\times$ (ℓ∞$/c_{0}$) is a predual of (ℓ∞)$^*$.
However, $c_{0}$ $\times$ (ℓ∞$/c_{0}$) is not isomorphic to ℓ∞.

Nice example Ady, that one has never crossed my mind. – Philip Brooker Jan 23 '10 at 0:49
More striking than this is that the separable space C[0,1] has dual which is isometrically isomorphic to the dual of the non separable space QC[0,1] (the uniform closure of the step functions on [0,1], so it is also a C(K) space). As Philip mentioned, JT provides a similar example, but of course is not isomorphic to a C(K) space. – Bill Johnson Jan 23 '10 at 16:29
IMO, to be "more striking" is only a question of taste. Since, in my example, the two preduals are homeomorphic, due to an easy application of the Michael Selection Theorem. – Ady Feb 1 '10 at 20:58

There are non-isomorphic preduals of $\ell_1$, but I'm afraid I don't know a reference for this. Recently, Argyros and Haydon solved a long-standing open problem by constructing a predual of $\ell_1$ with extraordinary properties; $c_0$ would not have done the job...
Actually, I now realize I'm not quite sure about the isometric version -- that is, what happens if you assume the duals are isometric and not just isomorphic. But I would be very surprised if the answer to your question was yes.

If K, L are countable compact metric spaces, then the isomorphism of C(K) and C(L) depends on the Cantor-Bendixson rank... If the first empty derived set of K is K^(n) and the first empty derived set of L is L^(m) and n \ne m, then C(K) and C(L) are not isomorphic. So, for example, C([0,w]) and C([0,w^2]) are not isomporphic. But (as noted previously) their duals are both isometric to l^1.

SQL Question
Retrieve same number of records in an ID IN query even with a duplicate
I'm using PostgreSQL. If I have an id in query say:
select * from public.record where id in (1,5,1);
this will only give me two rows, because the id 1 has a duplicate. But what if I want to display a set of records containing :
id | value
1 | A
5 | B
1 | A
Regardless of the reason why I would do this, is this possible?
Answer
You can do that by joining the values:
with ids (id) as (
 values (1),(5),(1)
)
select r.*
from public.record r
 join ids on r.id = ids.id;
If you need to keep the order of the parameter list, you need to add a column to sort on:
with ids (id, sort_order) as (
 values
 (1, 1),
 (5, 2),
 (1, 1)
)
select r.*
from public.record r
 join ids on r.id = ids.id
order by ids.sort_order;

Italianate Style

Fort Mason's commanding officer's residence, constructed in 1877 in the Italianate style.
History of the Style
The Italianate style, most prevalent in America between the 1850s and the 1880s, was inspired by rambling, informal Italian farmhouses and Italian-style villa architecture. The Italianate style placed an emphasis on the vertical orientation of the building, as if someone was pulling the top of the building up, and as if the building was made of putty, as it stretched upwards, the windows and door frames became narrower and attenuated. The dominant characteristic of the Italianate style was the low, overhanging roof with decorative eave brackets; there was often much decorative detail applied to the building just at the roof line. The windows were accentuated with thick, decorative hoods and the front entrances were often highlighted with a tower, a cupola or a projecting porch.
Italianate buildings were more playful and decorative than the earlier Greek Revival buildings and their floor plans designs were often asymmetrical. This style's popularity spread quickly across the country, partially as a result of newly-available building pattern books. These books, once considered too costly to reproduce, were now less expensive so families and builders alike could use them as reference manuals in designing their own buildings.
Italianate buildings at Golden Gate
While the civilian Italianate buildings in San Francisco were often wildly colorful and ornately decorated, the army's version of Italianate represented a more restrained and paired-down style. In both cases at the park - the Fort Mason Officers' Club and the Presidio Sutler's Buildingthe buildings were unique and not constructed from the standard army quartermaster plans. These two buildings were also originally constructed as residences and were both located in a highly visible part of their post.
The Fort Mason Officers' Club (Building 1), located on Franklin Street at Fort Mason, was originally built as the post's commanding officers' residence in 1877. This Italianate building has a hipped roof that extends past the buildings sides, with wooden decorated brackets. The windows are long and narrow and are outlined on all sides with thick moldings.
The Presidio Sutler's Building (Building 116) was built in 1885 as both a store and residence for the post's sutler, the man who sold goods and supplies to the soldiers. This building, located on Sheridan Road, has a hipped roof with a central, pedimented (triangular) element, decorative frieze under the roof line and a series of double pairs of multi-paned windows with decorative moldings. The building's design emphasizes its verticality.

1. Overhanging roof with decorative eave brackets
2. Thick, decorative window moldings
3. Decorative frieze band at 2nd floor level
4. Projecting wood-frame "porte cochere" (car port)

Mesmerizing video of 'Waterfall Clouds' in Aizawl goes viral
A mesmerizing video of clouds flowing off a height like a waterfall in Aizawl is going viral.
The video was shared on Facebook by Aziz Barbhuiya, and has been viewed and shared thousands of times on social media.
The viral clip shows clouds descending from a higher level to a lower one, with many saying it looked like a fluffy waterfall.
Watch the video here:
Waterfall Clouds
The stunning visual comes from a phenomenon known as orographic clouds that are commonly known as "waterfall clouds". These clouds are generally associated with a moist airflow over mountainous areas.
It usually occurs when stable air encounters a mountain, and is lifted upward, cooling as it rises. Water vapour in the moist air could condense, making it visible as a cloud. So when orographic clouds flow down from the tops of mountains, it often looks like a waterfall.

Sail to Lazaretto Island for a history lesson
Tourists who choose to go Greek Islands sailing know to hit some of the big name landmarks. However, there are smaller islands worth seeing during an adventure.
Those who are making a point to visit Corfu should also make their way to Lazaretto Island, which is just two nautical miles away. Although it's not as well-known as some of the other islands in the area, Lazaretto offers a lot of history.
Originally used as a leper colony in the 16th century, the island has held other uses. During the 1798 French occupation, the Russo-Turkish fleet ran a military hospital on the island, and the land was used again during the British occupation in 1814 after it received renovations.
The island is currently under renovation, as the church that resides on Lazaretto is being restored in order to become a museum dedicated to the National Resistance. During World War II, the island was used as a concentration camp for prisoners of the Greek National Resistance movement.

- Community groups or institutions
When should you honor colleagues?
Although any time is a good time to honor colleagues, there are some occasions when it's particularly appropriate.
Special occasions
These may have to do with the life of the organization, the life of the person being honored, or both. Some examples:
 - Retirement. Unfortunately, the reality is that most organizations and groups seldom honor colleagues until they leave.
If it is worth honoring a colleague, it is worth doing it before she is about to move on. It's great to have support for your work after it's done, but it's a lot better to have that support while the work is going on.
 - A significant anniversary. A number of years on the job, for instance, or a particular anniversary of the organization itself.
The staff members of an organization decided to honor their director, who had been in his position for ten years. To thank him for his leadership, his support and mentoring of staff, and his activism in the field, they held a reception to which they invited not only everyone in the organization, but directors of many other similar organizations, funders, and state bureaucrats - colleagues from several different contexts. The staff and others presented him with gifts, and many of the guests spoke of his contributions to the field and to their lives.
 - A personal milestone - a birthday, a wedding, the birth of a child.
We tend to think of pleasant occasions as the appropriate ones to honor colleagues, but others may provide a truer test of our respect for them. To have the support of colleagues at a funeral or while going through a difficult divorce may be honor of a different kind, but it's the kind that isn't forgotten.
 - The attainment of a personal or professional goal - a long-sought degree, a promotion, a certification.
The conclusion of something successful, or the achievement of a goal
The opening of a new facility, the culmination of a fundraising campaign, the passage of a favorable town ordinance - all might be good times to honor the colleagues who made them possible.
Regularly scheduled occasions
The annual meetings of coalitions, organizations, community groups, and professional associations are often times when colleagues are recognized or given awards for the work they've done in the past year. The adult education coalition mentioned earlier is a prime example, but the Human Resource Center and the North Quabbin Community Coalition, just to cite organizations that appear in other sections in this chapter, did or do the same thing. When reviewing a year's accomplishments, people often find it fitting to honor those responsible for them.
To say thank-you for a job well done or for support and mentoring
Despite the fact that there are particularly appropriate times to honor colleagues, sometimes it's right to honor colleagues simply because you want to. The realization that a particular colleague has been working effectively for a long time with no acknowledgement, or that she has been consistently helpful and supportive to others over a long period, might lead to a gift, or to some formal ceremony. This sort of appreciation is often the most powerful, because it is so obviously sincere.
Honoring colleagues doesn't have to be formal. It can happen every day in small ways. One coalition director used to send "thank-you" postcards to people to let them know she had appreciated something they did, or their ongoing work. A spoken word of praise, an acknowledgement of someone's hard work - perhaps most prized when that work hasn't yielded much - can make someone's day or week or year. Everyone needs to know she's valued, and it's important, both to an organization and the individuals who work in it, to remember and act on that as much as possible.
How do you honor colleagues?
There are a variety of ways to honor colleagues, but there are some general guidelines that apply to all of them.
General guidelines
Make it personal
Unless this is an award presented by a national or statewide organization to someone most of the members don't know personally, honoring colleagues is, in fact, highly personal. By honoring her, people in an organization or field are telling a colleague, someone they work with closely, that they appreciate her and consider her worthy of special recognition. Feelings of affection, gratitude, mutual dependence, and respect all come into play to varying degrees.
That being the case, any ceremony, gift, or simple recognition should be tied to the person receiving it as closely as possible. It's often a good idea to involve those closest to the honoree - close family, colleagues, mentors - and to make sure that the occasion includes stories about the person's significant accomplishments, about her personality, and about her as a human being. A gift should be something that fits both the person and the occasion. Every effort should be made to show that you're honoring this particular person, not just her achievements.
Give the honoree something
It may be a meaningful or significant gift (a photo of her with participants, a beautiful book or print, a super-light backpacking tent, etc.), a plaque or certificate, or a humorous gift with a personal story behind it. Whatever it is, there should be something material that the honoree can keep and look at later to remember the occasion.
A gift like this can be almost anything. At one celebration, the director of an organization was given a number of hats - a chef's hat, a baseball cap, a football helmet, etc. - to represent the different hats he had to wear to do his job. Another director, who collected them, was presented with a number of small, inexpensive wind-up toys that did silly things (a walking building, a tiny Godzilla that lurched and breathed sparks, a marching band of gorillas).
Obviously, whatever you give will be limited by your resources. Organizations sometimes collect from each staff member to buy a gift for an honoree, where that's appropriate (more common for a personal occasion - retirement, birthday, etc. - than for an organizational or professional award). Resources also have to be considered when deciding what kind of ceremony or celebration to have.
Record the occasion
Not only is this an important part of the work life of the person honored, but it's important in the life of the organization as well. Make sure to take photographs, or make a video or audiotape of the occasion, and give the honoree a copy, as well as keeping copies for the organization. If you have a digital camera or digital video camera, you can easily put photos or video on computer disks or CD's.
Think about the guest list
Whom will you invite? Who are the important people in the honoree's life? Will you invite dignitaries - politicians, people important in the field - or will you restrict the list to those who have real personal and/or professional connections to your colleague? Will you invite people he doesn't like because they "should" be there?
Consider inviting the media
If you want to publicize this occasion or award, if you want to use it to draw attention to your work or your organization, then the media should definitely be there. If honoring your colleague is a more private issue, and you feel that using the occasion for publicity would be exploitation, then you probably would not invite the media to be present. That doesn't mean, however, that you shouldn't issue a press release or try to get a media story about the honor after the fact. It's both a further honor to your colleague and a chance to let people know more about what you do.
Specific ideas
There are as many ways to honor colleagues as there are those who deserve to be honored and organizations or groups to do the honoring. Your options are really limited only by your budget and your imagination (and some considerations of taste: mud wrestling is probably out).
Make a personal gesture to show your colleague you appreciate him or her
A mention at a staff meeting and in the newsletter, a small gift left on a desk or chair, or an e-card are all ways to say "thank you" to a valued colleague. Small, personal gestures - especially if they're sincere, and not just a means to keep people satisfied - are an important way to let colleagues know you appreciate the work they do.
Present an award. There are really two choices here:
 - An award presented at regular intervals (usually annually) for a general purpose - Teacher of the Year, Innovation in Youth Work, etc.
 - A special award presented to the specific person for his unique contributions to the organization or the field
An annual award is usually more formal, more competitive (in that only one person a year gets it, although many may be worthy), and more prestigious. The other type may be more meaningful to the honoree, however, because it recognizes his personal talents, skills, and value to the presenting group.
Sometimes, a group may combine the two by occasionally presenting, along with its "regular" awards, a special recognition award to someone whose accomplishments don't necessarily fit into any category, or who has achieved something extraordinary. One coalition, at its annual awards ceremony, always presented several personalized awards to unsung colleagues who had made a difference that year in the life of the community.
Give a gift
We discussed gifts above, and the possibilities here are almost limitless.
In addition to the expected or ordinary, there are gifts you may not have considered:
 - Name something for them. A room, a program, a scholarship, a grant, an award - any of these and a host of other prospects might be fitting candidates to be named for an honoree.
 - Have a day in their honor proclaimed by the legislature, the county or city council, the Board of Health. In many states, the governor, if asked by the legislature, or the legislature itself, can proclaim a single day to be named

Streamlining Azure Arc Management: Automating DCR Checks with PowerShell
Introduction
In the evolving landscape of cloud computing, managing hybrid environments efficiently has become a critical task for IT professionals. Azure Arc, a service from Microsoft, stands out as a powerful tool in this area, enabling seamless management of resources across on-premises, multi-cloud, and edge environments. However, one particular challenge that arises in the realm of Azure Arc is the management of Data Collection Rules (DCR) for servers. These rules are vital for monitoring and data collection, but keeping track of them, especially in large environments, can be cumbersome and time-consuming.
Traditionally, this task involves manually checking each server to ascertain its DCR associations, a process that is not only tedious but also prone to human error. This is where automation can play a transformative role. In this blog post, we'll dive into the world of Azure Arc for Servers, specifically focusing on the management of Data Collection Rule associations. Our spotlight will be on a PowerShell script that I've developed to automate this crucial process. The script streamlines the task by listing all Azure Arc-enabled servers, checking for existing DCR associations, and then neatly tagging each server with this information.
By sharing this script, I aim to equip Azure administrators with a tool that not only saves time but also brings a level of precision and ease to the management of Azure Arc servers. Whether you're overseeing a handful of servers or hundreds, this script is designed to simplify your workflow and enhance your management capabilities. Let's explore how this PowerShell solution can make a significant difference in handling Azure Arc's Data Collection Rules.
The Role of Data Collection Rules (DCR) in Azure Arc
Within the Azure Arc framework, Data Collection Rules (DCR) play a crucial role. DCRs are primarily used for configuring and managing data collection for Azure Monitor, a service that provides full-stack monitoring across applications, infrastructure, and networks. Specifically, DCRs in Azure Arc are used to define what data should be collected from the machines, how it should be collected, and where it should be sent.
Data Collection Rules are pivotal for gaining insights into the performance and health of your hybrid infrastructure. They enable organizations to collect metrics and logs crucial for monitoring, troubleshooting, and ensuring compliance across their distributed infrastructure. By setting up DCRs, administrators can ensure that the right data is being collected at the right intervals, providing a detailed view of their environment's health and performance.
However, the challenge comes with the management of these rules, especially when dealing with a large number of servers. Ensuring each server has the appropriate DCRs and keeping track of these associations can become a complex task, which is where the power of automation through scripting becomes invaluable.
The Challenge of Manual Management
The Cumbersome Nature of Manual DCR Association Checks
In a perfect world, managing Data Collection Rules (DCR) for Azure Arc-enabled servers would be a straightforward, one-time task. However, in the dynamic environment of cloud computing, where configurations and needs constantly evolve, this process is far from static. For administrators, this translates to a recurring need to manually verify and update the DCR associations for each server. This task, while essential, is fraught with challenges.
The most apparent challenge is the sheer time consumption. In environments with a substantial number of servers, going through each server individually to check and update DCR associations is a tedious and time-intensive process. As the scale of the infrastructure grows, so does the complexity and duration of this task. This not only diverts valuable time and resources away from other critical activities but also introduces delays in updating or implementing new monitoring configurations.
Potential for Errors and Inconsistencies
Another significant drawback of manual management is the heightened risk of human error. Manual processes, by their nature, are prone to mistakes. These can range from overlooking certain servers to incorrectly configuring DCR associations. The implications of such errors are notable. An unmonitored server might go unnoticed, leading to blind spots in the infrastructure's health and performance monitoring. Similarly, incorrect configurations can result in the collection of irrelevant data or, worse, not collecting critical data needed for compliance and troubleshooting.
Impact on Responsiveness and Proactive Management
The manual process also impacts an organization's ability to be responsive and proactive in its infrastructure management. In a domain where real-time data and quick adjustments are key, any delays in configuring or updating DCR associations can hinder timely decision-making and action. This lag not only affects operational efficiency but can also have ramifications for compliance and security.
Given these challenges, the need for an automated, reliable, and efficient method to manage DCR associations is clear. In the following section, we will explore how a PowerShell script can address these challenges, turning a cumbersome manual task into an automated, streamlined process.
Script Requirements
 - Azure PowerShell Module
 - Permissions to read and modify Azure Arc connected machines, Data Collection Rules and tags.
Automating with PowerShell: Script Overview and Walkthrough
In the quest to overcome the challenges of manual management of Data Collection Rule (DCR) associations in Azure Arc, PowerShell emerges as a powerful ally. Leveraging PowerShell, I have developed a script that automates the tedious process of checking and tagging Azure Arc-enabled servers with their respective DCR associations.
High-Level Overview of the Script
The script is designed with simplicity and efficiency in mind. Its core functionalities include:
 - Listing Azure Arc Servers: The script begins by gathering all servers managed under Azure Arc. It uses Azure PowerShell cmdlets to fetch details of these servers, ensuring that no server is left unchecked.
 - Checking DCR Associations: For each server, the script then checks for existing Data Collection Rules associations. This step is crucial as it identifies what monitoring configurations are currently applied to each server.
 - Tagging Servers with DCR Information: Once the DCR associations are identified, the script tags each server with this information. The tagging includes a count of the DCR associations and, if necessary, the names of the associated rules. This tagging provides a clear, at-a-glance view of the DCR associations for each server, accessible directly within the Azure portal.

Script Walkthrough
The script operates in a few concise steps:
 - Connect to Azure: It starts by establishing a connection to your Azure account, ensuring access to Azure Arc resources.
 - Fetch Azure Arc Server Details: Using Get-AzConnectedMachine, the script lists all Azure Arc-enabled servers in your environment.
 - Evaluate and Tag Each Server: For each server, it utilizes Get-AzDataCollectionRuleAssociation to find any linked DCRs. The script then constructs a tag value, which includes the total count of DCRs and their names. It's important to note that the script also intelligently handles scenarios where the length of the tag value might exceed Azure's character limit.
 - Apply Tags: Finally, the script applies these tags to each server using New-AzTag, thus completing the automation loop.
This PowerShell script is more than just a time-saving tool; it's a step towards more intelligent, responsive, and efficient cloud infrastructure management. By automating what was once a manual and error-prone process, administrators can now focus on more strategic tasks, secure in the knowledge that their server monitoring configurations are consistently managed and up-to-date.
Azure Portal Experience
Reading Azure Arc Machine Tags and Converting from JSON
In managing Azure Arc-enabled servers, it's equally important to have a means to read and interpret the data that has been automated through the tagging process. To this end, I've developed another PowerShell script specifically designed to read the tags from an Azure Arc machine and convert them from JSON to a readable format. This functionality is particularly useful for administrators who need to quickly understand the monitoring configuration of each server without delving into complex JSON structures.

Conclusion
The PowerShell script presented in this blog post is more than just a tool; it's a step towards transforming the way Azure Arc-enabled servers are managed. By automating the tedious and error-prone process of checking and tagging DCR associations, the script significantly boosts efficiency, ensures consistency, and facilitates proactive management.
Its implementation is straightforward, requiring basic familiarity with Azure and PowerShell. The simplicity of the script, coupled with its powerful functionality, makes it a valuable addition to the toolkit of any Azure administrator.
I encourage you to try out this script in your environment. Experience firsthand how it simplifies and streamlines the management of DCR associations. Your feedback is invaluable; it not only helps in refining this tool but also fosters a community of shared knowledge and continuous improvement.

Contiguous Cache Example
QVariant RandomListModel::data(const QModelIndex &index, int role) const
 if (role!= Qt::DisplayRole)
 return QVariant();
 int row = index.row();
 if (row > m_rows.lastIndex()) {
 if (row - m_rows.lastIndex() > lookAhead)
 else while (row > m_rows.lastIndex())
 } else if (row < m_rows.firstIndex()) {
 if (m_rows.firstIndex() - row > lookAhead)
 else while (row < m_rows.firstIndex())
void RandomListModel::cacheRows(int from, int to) const
 m_rows.insert(i, fetchRow(i));
while (row > m_rows.lastIndex())
while (row < m_rows.firstIndex())
And thats it. A perfectly reasonable cache, using minimal memory for a very large list. In this case the accessor for getting the words into the cache generates random information rather than fixed information. This allows you to see how the cache range is kept for a local number of rows when running the example.
QString RandomListModel::fetchRow(int position) const
 return QString::number(rand() % ++position);
It is also worth considering pre-fetching items into the cache outside of the application's paint routine. This can be done either with a separate thread or using a QTimer to incrementally expand the range of the cache prior to rows being requested out of the current cache range.


text: Abstract CuO nanosheets were synthesized by an easy and green sonochemical method. It was found that, CuO nanosheets could significantly catalyse the chemiluminescence (CL) reaction of luminol–KMnO4 in an alkaline condition. Based on this finding, a new CL system (luminol–KMnO4–CuO nanosheets) combined with flow injection analysis has been developed for the determination of meropenem for the first time. Moreover, the CL intensity was enhanced when meropenem was presented in the reaction system. Under the optimum conditions, the enhanced CL intensity was proportional to the concentration of meropenem in the ranges of 0.005–6.00mg L−1, with a detection limit (3σ) of 0.0036mg L−1. The precision of the method was calculated by analyzing samples containing 1.0mg L−1 meropenem (n=11) and the relative standard deviation (RSD) was 1.7%. Also, a total analysis time per sample was 30seconds which confirmed the rapidity of the proposed assay. The practicality of the proposed CL system was evaluated by determining meropenem in spiked environmental water samples and human serum. A discussion on the possible CL reaction mechanism was also presented.

Instance provisioning on a Shared VPC network
This page lists the gcloud CLI commands needed to set up prerequisites, provision an instance in a service project, describe an instance, and delete an instance. In order to accomplish these tasks you should follow the instructions in each section of this page.
For more detailed guidance for these tasks, see the following pages:
Enable APIs
Enable the following APIs needed for configuring a service connection policy, configuring Shared VPC, and creating a Memorystore for Redis Cluster instance.
gcloud
 1. Enable the following APIs in the service project:
 gcloud services enable --project=SERVICE_PROJECT_ID networkconnectivity.googleapis.com
 gcloud services enable --project=SERVICE_PROJECT_ID serviceconsumermanagement.googleapis.com
 gcloud services enable --project=SERVICE_PROJECT_ID redis.googleapis.com

 Replace the SERVICE_PROJECT_ID with your service project ID.
 2. Enable the following APIs in the host project:
 gcloud services enable --project=HOST_PROJECT_ID networkconnectivity.googleapis.com

 Replace the HOST_PROJECT_ID with the ID of your host project.
Create a service connection policy
Next, a service connection policy must be created for the project, network, and region where you want to provision the Memorystore for Redis Cluster instance. Usually this is done by your Network Admin, or you might have the necessary permission run the command if you have the Required role.
This quickstart uses the default network and default subnet.
gcloud
 1. To create the service connection policy, run the create command:
 gcloud network-connectivity service-connection-policies create POLICY_NAME \
 --network=default \
 --project=HOST_PROJECT_ID \
 --region=REGION \
 --service-class=gcp-memorystore-redis \
 --subnets=_URL_

 Replace the following:
 - POLICY_NAME is your desired policy name.
 - HOST_PROJECT_ID is the host project ID.
 - REGION is the same region where you want to provision your Memorystore for Redis Cluster instance.
 2. To validate if the policy was created successfully, run the list command:
 gcloud network-connectivity service-connection-policies list \
 --region=REGION \
 --project=HOST_PROJECT_ID

 Replace the following:
 - HOST_PROJECT_ID is the host project ID.
 - REGION is the region where the service connection policy is defined.
Create an instance
To create an instance, run the following command:
gcloud
gcloud redis clusters create INSTANCE_ID \
--project=SERVICE_PROJECT_ID \
--region=REGION \
--node-type=NODE_TYPE \
--shard-count=SHARD_COUNT \
--replica-count=REPLICA_COUNT \
--network=projects/HOST_PROJECT_ID/global/networks/default
Replace the following:
 - INSTANCE_ID is the instance ID.
 - SERVICE_PROJECT_ID is the service project ID.
 - REGION is the region where you want to provision your instance.
 - NODE_TYPE is your chosen node type. Accepted values are:
 - redis-shared-core-nano
 - redis-standard-small
 - redis-highmem-medium
 - redis-highmem-xlarge
 For more details on node types and cluster configurations, see Cluster and node specification.
 - SHARD_COUNT determines the number of shards in your instance. Shard count determines the total memory capacity for storing cluster data. To see more details about cluster specification, see Cluster and node specification.
 - REPLICA_COUNT is your desired number of read replicas (per shard). Accepted values are 0, 1, and 2.
 - HOST_PROJECT_ID is the host project ID.
Describe the instance
To view instance details, run the following command:
gcloud
gcloud redis clusters describe INSTANCE_ID \
--project=SERVICE_PROJECT_ID \
--region=REGION
Replace the following:
 - INSTANCE_ID is the instance ID.
 - SERVICE_PROJECT_ID is the service project ID.
 - REGION is the region where your instance is located.
Delete the instance
To delete an instance, run the following command:
gcloud
gcloud redis clusters delete INSTANCE_ID \
--project=SERVICE_PROJECT_ID \
--region=REGION
Replace the following:
 - INSTANCE_ID is the instance ID.
 - SERVICE_PROJECT_ID is the service project ID.
 - REGION is the region where your instance is located.

ROLLING 30 DAY AVERAGE SHEET SUMMARY
Hello,
I'm looking to build a formula in the Sheet Summary that will provide a rolling 30 day average from the PROD values. (attached is a data subset) Feels like this should be fairly basic, but am struggling to find the solution. Anyone's help would be appreciated.

 Hi @Steve Erdahl
 Try this:
 =AVG(COLLECT(Prod:Prod, Date:Date, >=TODAY(-30), Date:Date, <=TODAY()))
 This will take the average of the first range (Prod:Prod), but only if the other column meets the criteria specified, which is why I used the COLLECT function.
 The other criteria is that the Date is either greater-than-or-equal-to (>=) 30 days ago (Today(-30)), OR that the Date is equal to today, or less (Today()).
 Let me know if it works for you!
 Cheers,
 Genevieve
 - HI Genevieve,
 Thank you so much for helping. Your assessment is exactly what I'm looking to do.
 When I input your equation, i get a "#DIVIDE BY ZERO" result. Any thoughts as to why?
 Appreciate the support!
 - Genevieve P.

 Hi @Steve Erdahl
 I just realized you have commas in with the data you would like to AVG. This indicates that the numbers are actually listed as text, not as numerical data that is able to be averaged. How is that information being input? Is this from a formula or a manual entry?
 If it's a formula, you could build in a VALUE function to ensure it's outputting a number instead of text... or what might be easiest is creating a helper column that simply has the formula:
 =VALUE(PROD@row)
 This will then create numbers and you can use this helper column as the first range in your AVG formula.
 Cheers,
 Genevieve
 - I have the "Thousands format" turned on to this column which adds the comma - visual preference. I tried the calc without the commas, but still get the #DIVIDE BY ZERO result.

 =averageif(date:date,>=today(-30),prod:prod) is a simpler way to do this.
 Check the dates. Depending on how you input them it might be 1920 instead of 2020 for the year.
 - Is it an issue that I have each date represented twice, once for a day shift and another for a night shift?
 - @Steve Erdahl my best guess on this is that your PROD column has text values and not numerical values, going back to what @Genevieve P mentioned.
 The reason this is likely, is that using the AVG function against text values will always return a #DIVIDE BY ZERO result. Creating a helper column and using =VALUE(PROD@row), then calculating using that helper column's data instead of your PROD column should do the trick!
 Thanks,
 Alex
 - Can this solution be used with avgif formula and rolling by quarter? Or would I just do =today (-90)?
 - Genevieve P.
 Genevieve P. Employee Admin
 Hi @Jermain Johnson
 You would want to use AVG(COLLECT instead of AVGIF since AVGIF can only identify one criteria, but in AVG(COLLECT you can specify a range, or two criteria.
 Yes, you can use =TODAY(-90) for a rolling quarter!
 Did you manage to get this to work?

 Hi @Genevieve P.
 Is there a way to only pull positive numbers from the data set for the average?
 thanks
 - Genevieve P.
 Genevieve P. Employee Admin
 Hi @Matt N
 Yes! In the COLLECT function you can reference a range and then identify the criteria as being "greater than 0". For example:
 =AVG(COLLECT({Range to Average}, {Range to Average}, > 0))
 Cheers,
 Genevieve
 - @Genevieve P.
 I have tried to place both the greater than zero AND rolling 90-day conditions in the formula and I get the #INVALID OPERATON result. Is there an order it has to come in? For example, do I need to set the greater than 0 condition first then the date condition or vice-versa or does it not matter?
 - Genevieve P.
 Genevieve P. Employee Admin
 Hi @Matt N
 The location of the {range} and "criteria" pair can be anywhere in the COLLECT function after the first range has been listed:
 =AVG(COLLECT(range to avg, range1, criteria1, range2, criteria2))
 In your test, it looks like you may have listed the [range] twice (before and after the criteria) instead of just once (before the criteria).
 It happens to be the same column you want to AVG, so we'll keep the listing there at the front as the first one. Then you can go ahead to list your criteria pairs, does that make sense?
 =AVG(COLLECT(Buffer Column, Buffer Column, greater than 0, Date, date criteria, Date, date criteria))
 The bolded sections can be rearranged, as long as the pairs are together. So this still works:
 =AVG(COLLECT(Buffer Column, Date, date criteria, Date, date criteria, Buffer Column, greater than 0))
 Try:
 =AVG(COLLECT([BUFFER OWREN VERONAL *17894 Usage (w)]:[BUFFER OWREN VERONAL *17894 Usage (w)], [BUFFER OWREN VERONAL *17894 Usage (w)]:[BUFFER OWREN VERONAL *17894 Usage (w)], > 0, DATE:DATE, >=TODAY(-90), DATE:DATE, <=TODAY()))
 Cheers,
 Genevieve

Are you tired of your audio device emitting an annoying crackling sound? Have you noticed that it only happens when you're reading Black Book? You're not alone. This issue is common among many audiophiles and can be frustrating. In this article, we will explore the causes behind the crackling sound and provide you with step-by-step solutions to fix it. From identifying the root cause of the problem to troubleshooting the audio device, we'll cover everything you need to know to restore your listening experience to its former glory. So buckle up and let's get started!
|Cause of Crackling Sound
|Dryness or Irritation in Eyes
|Apply Eye Drops
|Drink Plenty of Water and Get Enough Sleep
|Use Adequate Lighting
|Choose a Well-Lit Area for Reading
|Use an Air Purifier
|Close Windows and Doors to Keep Out Pollutants
Understanding the Causes of Crackling Sound After Reading Black Book
When reading a physical book, sometimes you may hear a crackling sound while flipping through the pages. This can be caused by several factors, including:
1. Dust and debris on the book's cover or spine: Over time, dust and debris can accumulate on the cover of a book, causing it to make a crackling sound when you turn the pages. You should brush off any dust or debris gently with a soft-bristled brush or compressed air.
2. Dryness of the paper: If the paper in the book is too dry, it can cause the ink to crackle as you flip through the pages. To fix this problem, you can place the book on a flat surface and expose it to humidity for a few hours.
3. Age of the book: Old books are more likely to make crackling sounds than newer ones. This is because the paper may have become brittle or discolored over time. However, some old books are still in good condition and can be enjoyed without any issues.
4. Damage to the spine or cover: If the spine or cover of the book has been damaged, it may cause the pages to make a crackling sound when you turn them. In this case, the book may need to be taken to a professional for repairs.
5. Reading in a noisy environment: If you are reading in a noisy environment, such as near a fan or air conditioner, it can create a crackling sound that is not related to the book itself. You should try to read in a quiet location to minimize any distractions.
Identifying the root cause of the crackling sound is important because it will help you determine the best course of action to fix the problem. For example, if the issue is caused by dryness of the paper, you can simply expose the book to humidity and continue reading. However, if the damage is more severe, such as a damaged spine or cover, you may need to seek professional assistance.
Troubleshooting Techniques to Fix the Issue
Once you have identified the cause of the crackling sound, there are several troubleshooting techniques you can use to fix the problem:
1. Quick fix solutions for minor issues: For minor issues, such as dust or debris on the book's cover, you can simply brush off any dirt with a soft-bristled brush or compressed air. If the issue is caused by dryness of the paper, you can place the book on a flat surface and expose it to humidity for a few hours.
2. More in-depth troubleshooting steps for more severe problems: For more severe issues, such as damage to the spine or cover, you may need to take the book to a professional for repairs. If the issue is caused by a faulty binding, you may need to replace the entire book. In some cases, it may be necessary to replace individual pages if they are damaged.
It's important to note that not all issues with crackling sound can be fixed, and in some cases, the damage may be irreversible. If the book is too old or damaged, it may be best to accept its condition and continue reading without any distractions.
Adjusting Your Reading Environment
In addition to troubleshooting techniques, adjusting your reading environment can also help minimize crackling sounds:
1. Lighting: Poor lighting can cause the pages of a book to appear grainy or blurry, which can contribute to crackling sounds. Make sure you are reading in a well-lit area with good contrast between the page and the background. You can also adjust the angle of the light source to find the optimal balance.
2. Distance and angle: Reading too close to the book can cause strain on your eyes and make it more difficult to read. Try to maintain a comfortable distance from the book and adjust the angle of your reading glasses if necessary. Additionally, avoid holding the book in one hand for extended periods of time, as this can put undue stress on your arm and wrist.
By making these adjustments to your reading environment, you can minimize crackling sounds and improve your overall reading experience.
1. Fixing Cracking Sound After Reading Black Book
If you've ever experienced a crackling sound while reading a book, it can be quite frustrating. Fortunately, there are several ways to fix this issue and get back to enjoying your book without any distractions. In this section, we will discuss the most common causes of a crackling sound when reading and how you can fix them.
2. Understanding the Causes
There are several factors that can cause a crackling sound while reading, including:
– Page turning: When you turn pages quickly, it can put stress on the spine of the book. Over time, this can lead to cracking sounds.
– Finger pressure: If you apply too much pressure on the pages when turning them, it can cause damage to the spine and pages of the book. This can also contribute to a crackling sound.
– Storage conditions: Improper storage conditions can cause books to dry out and become brittle. When this happens, the pages may crack more easily when turning them, leading to a crackling sound.
3. Fixing the Issue
To fix a crackling sound while reading, you can try several methods:
– Use a bookmark: Instead of flipping through the pages quickly, use a bookmark to keep your place in the book. This will reduce the stress on the spine and prevent damage to the pages.
– Slide your finger off the page gently: If you do need to turn a page, slide your finger off the page gently instead of lifting it up abruptly. This can help prevent damage to the spine and pages of the book.
– Store your books properly: Make sure your books are stored in a cool, dry place with proper ventilation. Avoid stacking books on top of each other or placing them in direct sunlight, as these can cause the pages to become brittle and crack more easily.
4. Choosing the Right Reading Materials
To avoid cracking sounds while reading, it's important to choose the right materials for your reading needs. Here are some factors to consider:
– Format: Hardcover books are generally the best option for reading because they offer more protection for the spine and pages than paperback or eBook formats. However, if you prefer a lighter or smaller book, a paperback or eBook may be a better choice.
– Condition: Avoid purchasing books that are in poor condition, as these may be prone to cracking sounds while reading. Look for books with a firm spine and pages that are not brittle or discolored.
– Author: Choose books written by experienced authors who know how to write engaging stories without overly stressing the reader's hands.
5. Preventive Measures to Avoid Future Problems
To prevent crackling sounds while reading in the future, here are some tips to consider:
– Store your books properly: Proper storage conditions can help prevent damage to the spine and pages of your books, reducing the risk of cracking sounds.
– Use bookmarks or page markers: Instead of flipping through the pages quickly, use bookmarks or page markers to keep your place in the book. This will reduce stress on the spine and prevent damage to the pages.
– Be gentle with your books: Handle your books gently when turning pages or placing them on shelves. Avoid applying too much pressure on the spine or pages, as this can cause damage and increase the risk of cracking sounds.
– Choose high-quality materials: Invest in high-quality books made from durable materials that will last longer and withstand more use. Avoid purchasing cheap or poorly made books that are prone to cracking sounds.
1. What is a crackling sound when reading a Black Book?
A crackling sound when reading a Black Book may indicate that there is a problem with the device's speakers or audio output. It could also be a sign of hardware failure or damage to the device.
2. How do I fix a crackling sound in my Black Book?

Manage DNS Zones With PowerShell
Adam Bertram
Adam Bertram
Read more posts by this author.
If you find yourself making changes on your Microsoft DNS servers using the DNS MMC snapin you're probably wasting a lot of time.
Why? Because it's possible to create, modify or remove any DNS object that you can from the MMC with PowerShell! By using PowerShell to manage DNS allows you not only control things from the command line but to take those commands and put them into a script to automate all kinds of time-consuming tasks.
To limit this article's scope, we're going to just focus on managing DNS zones with PowerShell although it's completely possible to administer other DNS objects like records and the server itself as well.
Before we get too far, there are a few prerequisites you need to be aware of. First, I'm assuming you have permissions to read, modify and remove DNS zones from your Windows DNS servers. Second, I'll be demonstrating a few concepts from DNS servers that are in an Active Directory domain with AD-integrated zones. PowerShell is still capable of managing zones and records outside of Active Directory but may not quite be the same result as I'll be showing you here. Finally, you'll need to ensure you have a version of the Remote Server Administration Tools (RSAT) installed on your client specific to your operating system.
Now that we have that out of the way let's start out by first ensuring the DNSServer module is available to us. To do that, I'll use the Get-Module cmdlet.
PS> Get-Module DnsServer -ListAvailable

 Directory: C:\Windows\system32\WindowsPowerShell\v1.0\Modules

 ModuleType Version Name ExportedCommands
 ---------- ------- ---- ----------------
 Manifest 2.0.0.0 DnsServer {Add-DnsServerConditionalForwarderZone, Add-DnsServerDirectoryPartition, Add-DnsServerForwarder, Add-DnsServerPrimaryZone...}

Great! It looks like our module is downloaded and we have some available commands. Let's now see what commands we have to work with DNS zones.

PS> Get-Command -Module DnsServer -Noun *Zone*

 CommandType Name Version Source
 ----------- ---- ------- ------
 Function Add-DnsServerConditionalForwarderZone 2.0.0.0 DnsServer
 Function Add-DnsServerPrimaryZone 2.0.0.0 DnsServer
 -- SNIP --
First up, let's create a zone with PowerShell. To do this, we'll use the Add-DnsServerPrimaryZone function. The simplest way this can be done is by using two parameters. Those parameters are Name and ReplicationScope. However, in our example, I'll also be using the ComputerName parameter since I'm invoking this command on a remote computer.
PS> Add-DnsServerPrimaryZone -Name testzone.mylab.local -ComputerName DC -ReplicationScope Forest
Above you can see that my domain is mylab.local and my zone name is testzone. My DNS server is DC so I'm specifying that for the ComputerName parameter and finally since this server is on my domain I have to also set the ReplicationScope so I've chosen to replicate this zone amongst all other DNS servers in my Active Directory forest.
Next, to verify this zone was created, I can then use the Get-DnsServerZone command. I could use the Name parameter but to show you all of the zones I have I'll just tell Get-DnsServerZone to find all of them.
PS> Get-DnsServerZone -ComputerName DC

 ZoneName ZoneType IsAutoCreated IsDsIntegrated IsReverseLookupZone IsSigned
 -------- -------- ------------- -------------- ------------------- --------
 _msdcs.mylab.local Primary False True False False
 0.in-addr.arpa Primary True False True False
 127.in-addr.arpa Primary True False True False
 255.in-addr.arpa Primary True False True False
 mylab.local Primary False True False False
 testzone.mylab.local Primary False True False False
 TrustAnchors Primary False True False F
And just to be sure we go through the entire lifecycle of a DNS zone, I'll then remove it.
PS> Remove-DnsServerZone -Name testzone.mylab.local -ComputerName DC -Confirm
This will also remove all the records in the zone, and the server will no longer host the zone, do you want to continue?
[Y] Yes [N] No [S] Suspend [?] Help (default is "Y"): y
 PS> Get-DnsServerZone -ComputerName DC

 ZoneName ZoneType IsAutoCreated IsDsIntegrated IsReverseLookupZone IsSigned
 -------- -------- ------------- -------------- ------------------- --------
 _msdcs.mylab.local Primary False True False False
 0.in-addr.arpa Primary True False True False
 127.in-addr.arpa Primary True False True False
 255.in-addr.arpa Primary True False True False
 mylab.local Primary False True False False
 TrustAnchors Primary False True False
Now that you've learned about DNS zone, why not pick up at the next logical spot and begin learning about DNS records in this detailed, step-by-step, tutorial on managing DNS records.
Summary
There is so much more possible with managing DNS zones in PowerShell. I encourage you to look through all of the commands possible in Get-Command -Module DnsServer -Noun Zone. This command gives you a list of all of the commands inside of the DnsServer module that have 'Zone' in the name. You'll find that the command names are self-explanatory and if you need to investigate further always consult the help of each command using Get-Help.
