now looking like a walk in the park - now they can add arbitrary concurrency!
Here, when Ian says "use the same set of local variables", he's talking about mutating the tail of the list, which might be shared by other heads. And he's right in one sense: if you modify the tail, you better mean it, because you're modifying shared state, not local state.
However, I have a couple of more aces up my sleeve. If desired, the transformation that turns sequential code into CPS can also turn mutating assignments into single static assignments. Single static assignment is a form used in some compilers in the back end to ensure that a variable can only ever have a single definition. If one could annotate one's variables, indicating if they should be shared across multiple continuations (stored in the tail) or strictly local to every continuation that redefines it (essentially, hidden in a scoping sense by the redefining activation record), this problem goes away.
The deeper objection I have to Ian's criticism is that you have to deal with this problem anyway, and program transformation just makes your life easier. Consider what you'd have to do to handle Back Button and Branching without using the approach sketched above. You have all the same problems. You still need to make sure that wherever you stuff away your state, that it isn't inappropriately used by the branches. SSA transformation can do this automatically and declaratively.
Consequently, this approach requires you to write your code in such a way that it can tolerate sudden halts, thread switches, rewinding, and forking of execution.
Sudden halts, thread switching, rewinding, forking: what is it in the tear-down and re-setup of the ASP.NET page cycle that stops you from seeing these things, if you choose to describe them that way? Tearing down the page is surely a violent halt. Setting up again, possibly on another machine, is surely a wrenching thread switch away from your carefully constructed state. To support rewinding / forking (aka Back button / new tab / window), you still need need to juggle your state so that it's correctly stored, keyed and associated with its page which was originally displayed to the user. But continuations can do *all* of these things with easier to read code, and selective SSA transformation turns a fiddly choice (should this data be in the database, in memory, in a cookie, querystring, hidden field, client-side state sent back through AJAX) into a declarative form which your Web library should be abstracting for you.
Does your web development environment supporting continuations? If not, why not?
I will give Ian something, though. It's certainly not true (and shouldn't be true) that one simply writes a sequential application using continuations without thought for the network and then expect it to work fine across the web. That can't happen. However, I do believe that with the correct libraries, language, annotations and transformations, a far better language for web apps can be created. Whether it'll be along the lines of Volta, or one of the frameworks described herein, I don't know. However, I strongly suspect new language constructs, or at least flexible DSL support, is necessary. I can even think of implementing continuations using monads, so perhaps it'll be Haskell!

It is not my intention to misrepresent anyone.
The key phrase here is "linked list". You use it several times.
A node in a linked list presents a linear view. Navigation through the web needn't be linear, and frequently isn't. I know you have responded to this, but I think you've missed an important point. You say that continuations "can capture an arbitrary history tree of independent, concurrent user journeys" but while that's true, the tree is not visible in tree form to code running in the web application. The tree does not form part of the programming model: the web application only ever sees one path through the tree - it only ever sees lines. It may see different lines at different times, but the model it presents is always linear.
What, you may ask, of the fact that it sees different lines at different times? Yes, a tail may be shared by multiple heads, but looking at the view available from the point of view of any one particular node, it looks linear - linked lists don't give me a way to join multiple paths back together. The tree may exist, but my code never sees it as a tree, because the continuation model always shows me the view from a particular node. I never see the tree as a tree. This matters.
One practical upshot (not the only one) is that the tree is as good as pruned the moment the user has no way of getting back to a particular path they abandoned. E.g.:
1. On page A
2. Click to page B
3. Click to page C
4. Back (now on B again)
5. Click to page D
That path that started on step 3 - where is it now? It's probably still a leaf in a tree on the web server at this point, but because the browser will have pruned that branch from its history, the corresponding branch on the server will never be seen again, unless you get a core dump and go looking for it with a debugger, or go ferreting around in your continuation persistance store. As far as the code running on your web server is concerned, the path started in step 3 is gone for good.
The code that ran to serve up page D on step 5 will not see evidence of that click to page 3. At least, if you've used single static assignment as you suggest there will surely be no evidence at all - any work done in 3 will be stored in come continuation that there's no longer any way of getting to. The user's browser will have discarded that path as soon as step 5 occurred, so even though your server may be maintaining a tree structure that still has that continuation in some form, the browser has just discarded the information that would have been required to get to it.
So unless your server has some mechanism to get the work done in step 3 back onto the branch we entered on step 5, that work is gone for good, along with any data the user may have supplied on that step.
Of course, you could allow mutation of state shared between continuations, on languages that support this, and that would provide a way for side effects in step 3 to be visible to step 5. But I hope you would agree that madness that way lies - you proposed single static assignment, and speaking as (amongst other things) a Haskell developer, I wholeheartedly agree with that as a strategy. But you now need some other mechanism (e.g. state in the database) if you want work done in step 3 not to be lost.
That's what I mean when I say that I don't think continuations deal with non-linear navigation. Their'solution' to non-linear navigation is to act as though none of the forks ever happened.
On that point, you spoke about the "main trunk" of interaction. This is a telling phrase. It reveals a presumption of an underlying linearity, and this illustrates exactly what I'm talking about. You suppose that there is a'main trunk' of interaction. This supposition is at the heart of continuation based frameworks. Unfortunately, this supposition is wrong.
That's the fundamental problem. That's why I identified it as "the killer." Apparently I've not explained myself well - rather than directly disagreeing with this point you said that you "don't know what Ian is talking about". So I'm going to try and explain this one point a little better.
Much as I want to reply point by point (and please email me if you want to follow this up in more detail), I fear that the key point will be lost in the detail, just as it apparently was with the original post. With hindsight I wish I hadn't bothered with most of the other stuff - I believe it's real and more relevant than you give it credit for, but it's prosaic stuff, and not really at the heart of the problem.
The heart of the problem is that web navigation is not linear. As far as I can tell (and your post, with its presumption of a "main branch" seems to reinforce this) continuation-based frameworks present web navigation to the developer as though it is linear. Indeed, most web continuation advocates seem to think that's a positive feature, perhaps even the point. I think it's a problem.
Pretending that a linear view of a user's navigation can accurately represent their work will hurt the user more than it hurts the developer. That's a problem if you're a user.
"Make the easy case easy, and the hard case ignorable; screw the users" is, I hope, not a motto any developer would aspire to. And yet this seems to be the upshot of continuation-based web frameworks, if what you say here is correct.
Here's a simple concrete example. Suppose I'm on Amazon, and I've decided to buy a book. I click the necessary links to add it to my basket. Then I decide I'm going to buy another one that I saw earlier, and for whatever reason it's not one of the ones Amazon has decided to show on the "why not buy these too" type page. So I just open the Back popup to skip back a few pages and find the book I wanted. Then I go through the purchase process again.
My navigation path wasn't linear here. It's forked. If a linked list truly is a good representation, I

- As shown in the example above, this method is useful when you have to execute several different queries to the database in the same script. Besides, improve the execution speed of the script, make it more efficient to work with multiple SQL queries.
Between SQL commands which are "pending", you can add various PHP instructions to influence the next command (such as SELECT here was defined according to the latest "id" created by the previous query).
- The script above will output this result:
Last inserted id: 4
Courses - Tutorials - _URL_
PHP-MySQL Course - _URL_
Spanish Course - _URL_
If the ATTR_ERRMODE is set to ERRMODE_WARNING (with the setAttribute() method), and an error ocurs to one of the SQL instructions between beginTransaction() and commit(), the next SQL instructions after the query which has generated the error will not be executed.
But if it's not specified the ERRMODE_WARNING mode, the PHP continues the execution of the other queries too.

ES STEAM Week 2021
STEAM Week kicked off with grade level assemblies on March 18th. Students learned that celebrating STEAM week is about bringing together their scientific and mathematical thinking skills as well as elements of art and engineering to design and create solutions to problems. Technology was incorporated through the tools that students used to plan, develop, and communicate about their STEAM projects. The theme of STEAM week this year was Sustainability in our World.
Students showed their ability to reuse and repurpose materials in the ES Upcycling Competition. They were challenged to make new items out of old materials and winners were chosen in each grade level. These winners earned 100 house points for their house. All entries were awarded 10 house points and students were invited to show and tell their upcycled projects both on campus and on Zoom. The creativity and innovation of EC and ES students is inspirational.
G2-G4 students had a virtual visit from Redress, a sustainable clothing charity based in Hong Kong. Students learned about the materials that our clothes are made from, and if these materials come from renewable or non-renewable sources. We also learned what we can do with our old clothes – we can Repair, Donate or Upcycle! G2-4 also had a virtual visit from PRAISE-HK, in which they learned about the dangers of air pollution on our health and the major air pollutants in Hong Kong. Students learned the causes of air pollution and how leading a more sustainable lifestyle can help reduce air pollution and improve the air quality for the future. They also learnt about the technology being created by PRAISE-HK and the University of Hong Kong Science and Technology to tackle air pollution.
EC and G1 students were visited by some exotic animals. Toni (also an AIS parent) from Jurassic Garage introduced our students to a huge spider, snakes, a hedgehog and more creatures during the Zoom session. In connection with sustainability, students learned about the habitats of these animals and how we can protect them. They learned the importance of keeping our land, air, and water clean so that animals like the axolotl may someday be able to breed and thrive in their natural habitat.
On campus, students in Grade 4 competed in the second annual Great Eagle Egg drop. In teams of two, the students used recycled materials to design and build a structure that could protect our eagle eggs. We dropped our structures from the 1st and 2nd floors and all of the unbroken eggs won house points!
Grade 3 students learned what made bridges strong. Students collected materials at home according to their plans and when they returned to campus, the construction began. Students worked for 2 days, constructing bridges and testing them to see how much weight they held. We learned how to address failure points to improve their ideas. Finally, the day for the bridge competition arrived and all students were able to participate and cheer each other on. All bridges were successful and students left the day feeling proud!
On campus, Grade 2 students took part in a recycled Easter Egg basket challenge and showed great engineering and creativity skills! The students also did a science experiment looking at water transportation in plants, to coincide with our current science project, 'Interdependent Relationships in Ecosystems'. At home, students participated in an at home challenge involving taking fruit or vegetable food scraps and regrowing them into new plants. They recorded their plant's growth by creating their own digital plant diaries on 'Book Creator'.
Grade 1 participated in a building challenge. As an introduction to our upcoming life science unit, students began looking at the structures of different animals and used uncooked spaghetti and marshmallows to build animals. Students focused on planning and design, building the structure, and troubleshooting when things didn't go as planned. The hardest part was not eating the marshmallows while they worked!
Grade 1 Junior celebrated STEAM by making paper planes. The little engineers learned the concept of forces of flight like lift, thrust, and weight. They demonstrated their willingness and ability to follow instructions while folding their papers carefully. The creative minds then worked on decorating their planes with beautiful designs. And then came the most exciting part when they enjoyed flying their paper planes outside their classroom. They compared and measured whose plane has gone farthest and why? Troubleshooting is what engineers do all the time. Kids came back to their classes with the thought of how they can re-engineer their folds to have a higher flight next time!
In Early Childhood 2, students used their STEAM skills and knowledge to build animal homes to protect them from predators. The students learned about animals and their needs. Animals are important for our ecosystem, and they also need a safe environment just like people. Students were creative in making animal homes with popsicle sticks and clothespins.
Early Childhood 1 students read the book "The 3 Little Pigs". They incorporated all the elements of STEAM to build a house for their animals. The goal was to make a house that can stand up best to "wolf blowing". The students used, explored and discussed a variety of materials and tools, experimenting with design and texture. They had a blast!
STEAM Week was especially memorable this year because it brought grade levels together to participate in something as a community. Students were able to connect with friends they have not seen much this year and enjoy a whole school event together. Thank you parents, teachers, and the whole AIS community for supporting a week of STEAM in Elementary School!

I consulted Advanced Practical Organic Chemistry (John Leonard) and Practical Organic Synthesis (Reinhart Keese). Both have useful paragraphs on dry loading, but one point is not clear. Does one use sand, and if so, is the sand above or below the sample-impregnated silica?
Sand on top of the sample loaded silica. So I make up the column, either wet or dry load, then add a bunch of sand, enough to protect the sample loaded silica so my cack-handed pouring of solvent doesnt disturb the sample layer.

Caxton was the first English printer and a translator and importer of books into England.
Caxton was born in around 1422 in Kent. He went to London at the age of 16 to become an apprentice to a merchant, later moving to Bruges, the centre of the wool trade, where he became a successful and important member of the merchant community. From 1462 to 1470 he served as governor of the 'English Nation of Merchant Adventurers', which allowed him to represent his fellow merchants, as well as act as a diplomat for the king.
Caxton affiliated himself with the household of Margaret, the duchess of Burgundy, sister of the English king Edward IV. She became one of his most important patrons and encouraged him with his translation of 'The Recuyell of the Histories of Troye' from French to English. In the early 1470s Caxton spent time in Cologne learning the art of printing. He returned to Bruges in 1472 where he and Colard Mansion, a Flemish calligrapher, set up a press. Caxton's own translation of 'The Recuyell of the Histories of Troye' was the first book printed in the English language.
In 1476 Caxton returned to London and established a press at Westminster, the first printing press in England. Amongst the books he printed were Chaucer's 'Canterbury Tales', Gower's 'Confession Amantis' and Malory's 'Le Morte d'Arthur'. He printed more than 100 books in his lifetime, books which were known for their craftsmanship and careful editing. He was also the translator of many of the books he published, using his knowledge of French, Latin and Dutch. He died in 1492.

When peak performance is unnecessary, Dynamic Voltage Scaling (DVS) can be used to reduce the dynamic power consumption of embedded multiprocessors. In future technologies, however, static power consumption due to leakage current is expected to increase significantly. Then it will be more effective to limit the number of processors employed (i.e., turn some of them off), or to use a combination of DVS and processor shutdown. In this paper, leakage-aware scheduling heuristics are presented that determine the best trade-off between these three techniques: DVS, processor shutdown, and finding the optimal number of processors.

- Year of Study:
My MA dissertation (SOAS, 2008) focussed on non-worshipped animals in popular Indian cinema, using animal theory and anthropological theory of the body. I have since written 'Mouse (Animal)' (forthcoming) for Reaktion Books' 'Animal' series, also authored by writers to include Desmond Morris ('Naked Ape', 1967).
Emerging from my deep interest in human-animal relationships, animal symbolism and the myth and literature of South Asia, my PhD research considers the socio-religious significances of fish (and'sea monster') characters and symbols in tellings of India's epics, pertaining to gender and the body: to aspects of monstrosity, sexual morality, and fantasy.

Residual solvents are chemicals that pharmaceutical companies use to manufacture different prescription drugs. They have various degrees of toxicity that are classified according to three levels. Sometimes, residual solvents are by-product of the manufacturing process. They are considered to be organic volatile chemicals that most drug manufacturers are required to remove as much as possible from their finished products.
The pharmaceutical industry uses residual solvents in a variety of manufacturing methods. Sometimes the chemicals are used to combine a drug's ingredients. Solvents may also be used to transform drug ingredients into a different form, such as crystals. They might be used to prepare the ingredients prior to the manufacturing process. At other times, residual solvents are produced as a result of combining the drug's ingredients.
Since drugs are essentially a combination of isolated chemical compounds, mixing them together can sometimes result in by-products that the manufacturing process is unable to remove completely. If manufacturers are aware that the production process of certain drugs is likely to result in residual solvents, they are usually required to test for them. Toxicity levels and types of solvents are measured. In order to adhere to national safety guidelines and ethics regarding human exposure to chemicals, manufacturers can only allow certain levels of solvents to remain in their finished products.
Ad
According to product specifications, drug manufacturers must remove certain amounts of residual solvents from their final products. There are a set of solvents that should not be used during the drug manufacturing process due to high levels of toxicity and safety concerns. Some of those organic chemicals include benzene and carbon tetrachloride. Other solvents that most manufacturers attempt to avoid include dichlorethene and trichlorethene.
A second group of residual solvents that might be used in the drug manufacturing process is considered to be somewhat lower in toxicity. Manufacturers are still required to limit the use of these chemicals, but are permitted to include them in the process under certain circumstances. Some of those chemicals include sulfolane, tetralin and chloroform. The level of these chemicals permitted to remain in finished drug products must not exceed national safety levels.
Low toxicity solvents are permitted to be used to manufacture drugs, but must not be used excessively. Similar to their somewhat more toxic counterparts in group two, only the maximum amounts per national safety levels are permitted. The risk that these solvents pose to humans is usually considered to be insignificant enough that their formal identification is not required by national governments and manufacturers.

Our main interest is the question of how neural ensemble activity represents sensory stimuli. In this paper we discuss a new approach to characterizing neural coding schemes. It attempts to describe the specific stimulus parameters encoded in the neural ensemble activity and at the same time determines the nature of the neural symbols with which that information is encoded. This recently developed approach for the analysis of neural coding [7, 9] minimizes an intrinsic information-theoretic… CONTINUE READING


Parish Registration
Registering at St. John's is easy. Just download the registration form below and fill it out. You can drop the completed form off at the parish office Tues.-Fri. between 8am and 4pm or email it to
Membership in a parish and registering at a parish are not the same thing, although they are often spoken of interchangeably. A "parish" consists of a geographical area with clearly defined boundaries, which has its own church or chapel belonging to it and its own pastor administering it. Any Catholic who lives within the physical boundaries of a parish is automatically considered a "member" of that parish for purposes of administering the sacraments. He/she cannot be refused the sacraments by the pastor of the parish in which he/she resides unless the pastor has a valid canonical reason to do so. For example, when a Catholic marries, the pastor of the parish within whose boundaries he/she resides has a responsibility to witness the marriage, unless there is a valid canonical reason for him to refuse (e.g., the person is already validly married to another spouse).
Being registered at a parish is different. One becomes registered at a parish when one fills out a census form, regularly contributes to the parish's finances, or otherwise "signs up" at the parish. Registering is primarily useful for administrative purposes. Keeping a parish registry allows pastors and administrative staff to keep track of who is worshipping at the parish and contributing to the parish's financial needs. However, a pastor is not required to provide "one-time" sacraments, such as marriage or baptism, to a registered person who is not a geographical member of the parish.
Registering at a parish has a lot of great benefits, including having one's contact information on record at the parish and being able to receive important communications, having an established sacramental record, and receiving offertory envelopes, which make it easier to keep track of contributions.
Here are some interesting articles on the historical development of parishes and on the difference between parish membership and registration.

Language Trends Wales 2019
This report presents the findings of the fifth annual Language Trends Wales survey of secondary schools, and the second such survey of primary schools in Wales.
The report gathers information from 269 Welsh schools about the current situation for Modern Foreign Language (MFL) teaching and learning in Wales.
The huge decline in MFL exam entries in secondary schools continues, however a more positive picture is emerging at primary level.
View a blog from our Country Director, Jenny Scott who shares her thoughts on the report here.
Headline statistics from the report include:
- Since 2002, entries for GCSE in MFL have declined by 60% in Wales and continue to fall year-on-year
- 39% of responding secondary schools have no take up or provision of MFL for A-Level in 2019 compared to 29% in 2018 and 20% in 2017
- 73% of schools say the difficulty of MFL exams is putting off pupils at GCSE and A level.
- MFL GCSE take-up is stratified along both academic and socio-economic lines, with students receiving free school meals or with special educational needs or disabilities less likely to take the subject
- The implications of Brexit are seen as a challenge in 41% of schools.
- Welsh is seen as fulfilling the 'language slot'; responses show a connection between the decline in MFL entries over the past five years and the increase in entries for Welsh
- Primary schools are increasing their MFL provision – 39% of schools said they provide some form of MFL lesson, compared to 28% in 2016. Welsh medium primary schools are embracing international languages at a faster pace than their English-medium counterparts.
- There is a danger of a lost generation of language learners as children engaged at primary find no provision in secondary.
- Welsh-medium primary schools are more likely to be teaching international languages than other types of school.

Service life prediction of fiberglass reinforced plastics corrosion resistant equipment (by monitoring while in service to determine any deterioration or damage to the corrosion barrier)
The non-destructive test system called FRP Corrosion Resistant Barrier Deterioration and Damage Detection that is described can be run while the FRP equipment is in service. The system can alert chemical plant companies to changes in the chemical corrosion barrier which can allow corrective action to be taken before any leaks or releases of chemicals occur. The paper covers the fundamentals, history and development of a concept into a plant-scale working test system. Properly implemented, the system can reduce equipment inspections needed and give substantial reductions in maintenance costs and the need for confined space entries.

I previously discussed the use of Hierarchical Triangular Mesh (HTM) geometry with a Tessellated Octahedral Adaptive Subdivision Transform (TOAST) projection, and a geometry based on latitude and longitude with an Equirectangular projection. Currently the project is using the following:
- HTM for background stars (both for spatial indexing and deciding which cells to render).
- Equirectangular projections for texturing on planetary bodies.
I thought it would be useful to discuss the combination of geometry and projection with respect to the following:
- Polar Distortion
- Tile Distribution
- Virtual Textures
- Normal Mapping
- Texture Scaling
- Cloud Shadowing
TOAST projections have the advantage of suffering less distortion than equirectangular projections near to the poles. Currently it appears to be easier to find data in equirectangular projection. The Sphere TOASTER tool for WorldWide Telescope allows re-projection from equirectangular to TOAST. However, since the source maps already suffer from polar distortion, the resultant TOAST projections also have poor resolution in polar regions. Finding undistorted data would solve this issue.
Spatial mapping using grid cells based on HTM has a more even distribution than cells based on latitude and longitude. I am therefore using HTM for background stars. This gives an even spatial index, and a more even number of cells to render with respect to camera orientation.
It is easy to generate level-of-detail tiles from an equirectangular source maps using a simple tool. Generating tiles for a TOAST projection from an equirectangular projeciton is possible using the Sphere TOASTER tool for WorldWide Telescope.
Normal mapping using equirectangular projections is straightforward, however leads to texture seams when using TOAST. Since I wanted to use normal mapping for specular lighting, equirectangular maps were more appropriate.
While waiting for virtual texture tiles to load from a cache, I take a parent tile and divide and scale it accordingly to give a lower-resoultion texture. In the case of an equirectangular projection this is a simple algorithm.
I also wanted to cast shadows from clouds. In the case of an equirectangular projection, there is simple algorithm in the pixel shader for converting between texture and model space.


the current tile), set the current tile's state to the opposite of the tile to its left. Otherwise, set it to the same as the tile to the left. Goto 4.
 3. If the current tile is not part of the chain, set the tile to the state of the title to its left. Goto 4.
 4. The tile one to the right is now the current tile. Goto 2.
Now take all the tiles which are IN, add in the tiles on the border (including a tail if you stripped it earlier or not, your choice), and call that the region.
If you want to allow the user to use borders, remember that this does not define and IN/OUT on the board, but just divides it into two parts. You could select the smaller region, for example, or require the user to use two adjacent sides (i.e., the left and bottom, but not either top/bottom or left/right).
An optimization is that you only need to do rows which have any border in them (if you can't use the sides). I assume that your board is small enough that iterating over every tile and doing a very simple computation is not an issue, even on the weakest mobile system. (You do have to render them, after all, which is far more complex of a task).

Consumer Behaviour of Purchasing Digital Camera
1.0 Introduction
In order to market the product into the market successfully, marketers need to have some marketing strategy to enter the desired market and make profit. Market segmentation is the process of dividing a market into subsets of consumers with common needs or characteristics (Schiffman et al., 2011). Understanding the market size and segmentation is valuable, but the keys to effective targeting is to know just how valuable specific consumer groups are, and being able to quantify the impact of consumer trends ( Berry, 1999).
The purpose if this paper is to define the market segmentation for digital camera. Especially focus on Nikon digital camera which is the chosen product in

According to the consumer feedback survey conducted by Nikon in 2011, the consumers considered Nikon digital camera as user-friendly, affordable price, well performance and good quality. The significant signal to explain this stage can be affordable price and good quality of the product.
2.1.2. Product benefits
After the product attributes it goes to the second stage which is product benefits. There are two consequences can discussed under the field of product benefits, namely as functional consequences and psychosocial consequences.
The functional consequences is the tangible consequences of the product, it focus more on "what function is perform?'Also, it can be considered as an external influence to the consumer. In this case the consequences may be user-friendly and excellence photographic performance.
The psychosocial consequence is a combination of psychological and social consequences. It emphasized more on 'How I feel?' and 'How people feel about me?'which is more likely to be the internal influences to the consumers. Attraction and communication are significantly elements in this part. For example, Nikon consumer may feel they catch people attention when they are using Nikon digital camera which is the psychological consequence. Also the consumer may feel happy when they are using Nikon digital camera with others and create positiveexperience about the product, this may considered as social consequence.

As the first postage stamps issued by the Bureau of Engraving and Printing, the Series of 1894 holds a unique position in U.S. philately. Generations of collectors have referred to the series as the 'First Bureau Issue'. The stamp designs were the legacy from the American Bank Note Company dies, to which the Bureau added 'triangles' in the upper corners. Until July 1894, when the first stamps of the series was issued, private companies had printed all postage stamps under contracts with the Post Office Department.
Series of 1894 stamps are categorized in three groups based primarily on whether or not watermarked paper was used and on color. The series includes thirteen denominations, ranging from one cent to five dollars.
Issued in July 1894, the first denomination of the first group was the 6-cent Garfield stamp. Most of the other stamps were issued in the fall of 1894, though the 8-cent Sherman was not issued until March 1895. The Bureau of Engraving and Printing issued all stamps in this first group on unwatermarked paper, just as the American Bank Note Company had done.
A decision was made in 1895 to print stamps on watermarked paper. Series of 1894 stamps that had only recently appeared on unwatermarked paper now appeared again on paper with a double-line USPS watermark. They were the first postage stamps printed on watermarked paper and constitute the second group of stamps in the First Bureau Issue.
The third group in the First Bureau Issue includes stamps whose colors were changed to conform to Universal Postal Union regulations. The 1-cent Franklin was changed from blue to green and the 5-cent Grant from chocolate to blue. In order to avoid confusing postal clerks and the public, the 10-cent Webster, previously printed in green, was reissued in brown and orange brown, and the 15-cent Clay, previously printed in blue, was reissued in olive green.

What is the Water Quality in San Jose, California?
Compared to other US cities, San Jose water quality ranks in the high range for contamination excluding Lead.
Most of their 39 contaminants have cancer-causing attributes.
- Chloroform is at very high levels: 30x health guidelines.
- Haloacetic acids (HAA5) are at extremely high levels: 139x health guidelines.
- Haloacetic acids (HAA9) are at extremely high levels: 276x health guidelines.
- These are both byproducts of the chlorine treatment process most water supplies go through.
- PFOA is at high levels: 9.6x health guidelines.
- This is considered a "forever chemical" by the EPA and is being studied extensively.
Let's look closer at what's in San Jose water.
What's in San Jose water?
Here are the top 5 chemical compounds in your water and what health issues they can potentially cause:
- Bromodichloromethane – Potential effect: Cancer
- Chloroform – Potential effect: Cancer
- Haloacetic acids – Potential effect: Cancer
- Hexavalent Chromium – Potential effect: Cancer
- Total trihalomethanes – Potential effect: Cancer
These are five of the 39 contaminants analyzed by the Environmental Working Group (ewg.org).
15 of these contaminants are rated as exceeding EWG Health Guidelines.
Does San Jose have Lead contamination?
No, San Jose does not have lead in its water. The most recent Lead samples collected in 2019 showed concentrations of 0.0 parts per billion (ppb).
The legal limit for lead is 15 parts per billion. Being well-below this level is a good thing.
- Concentrations between 3.8 ppb and 15 ppb put a formula-fed baby at risk of elevated blood lead levels. Read more about the symptoms of Lead in water.
There is no safe level of lead for humans.
- The good news is that 99.99% of the lead can be removed.
See the What Can You Do? section below to learn how to filter out contaminants.
Where does San Jose's water come from?
San Jose's water comes from the San Jose State University – Frontal San Francisco Bay Estuaries watershed.
There are no EPA assessed water sources in the San Jose State University – Frontal San Francisco Bay Estuaries watershed.
Ideally, a water source would be Known, Assessed, and rated in Good condition.
Whether a water source is in Impaired or Good condition refers to the quality of these uses:
- Drinking Water
- Aquatic Life
- Fish and Shellfish Consumption
Learn more from How's My Waterway
See below for what you can do to improve San Jose's water.
What Can You Do?
Information about water quality in San Jose can be surprising.
But there are things you can do in your home to clean up your water.
To Remove Lead and Other Contaminants In Your Home:
There is one solution that beats Brita, PUR, and expensive whole house systems.
- It costs less per gallon.
- Needs fewer filter changes.
- And it doesn't make your water taste weird.
- Use Berkey filters with activated carbon to filter out at least 85% of contaminants in your drinking water.
- To filter out 36 of the 39 contaminants (92.3%), consider a Reverse Osmosis water filtration system for your house.
- These are more expensive than pitchers to purchase, but can be more effective.
- They have the benefit of filtering out heavy hitters like:
- 1,4-Dioxane – "Exposure may cause damage to the central nervous system, liver and kidneys."
- Barium – In low doses, barium ions act as a muscle stimulant, and higher doses affect the nervous system, causing cardiac irregularities, tremors, weakness, anxiety, shortness of breath, and paralysis.
- Bromodichloromethane – health risks in drinking water
- Chloroform – side effects
- Chromium (total)
- Dibromoacetic acid
- Dichloroacetic acid
- Haloacetic acids – chlorination byproduct*
- Hexavalent chromium – health effects
- Monobromoacetic acid
- Monochloroacetic acid
- Selenium – toxicity
- Total trihalomethanes – byproduct of chlorination*
- Trichloroacetic acid
*Chlorination is an effective method of disinfecting/treating drinking water. You can then use a water filter to reduce the effects of chlorination byproducts to get the safest, cleanest water possible.
In Your Community:
Contact your local government officials and put pressure on them to invest in cleaner waterways and upgraded city water filtration and treatment.

The study of chemical parameters at hydrothermal vents is important. As hot effluent encounters the cold seawater (~2 degrees C), minerals precipitate from the element-rich vent water. Black smoker vents are found in areas where the effluent is very hot (~350 C). These types of vents precipitate iron sulphides, giving rising plumes a dark colour and cause the formation of sulphide-mineral deposits on the seafloor.

Two numerical particle transport tests were performed to verify the implementation of the TDRW method into UDEC, that is, particle transports in a single fracture and in a simple facture network.
The analytical solution is to be used later to verify the numerical results obtained with combination of DEM and TDRW. For simplicity, the analytical solution for advection-dispersion transport equation with constant concentration injection is adopted, which can be written as follows:
The corresponding numerical solution was obtained using the TDRW method implemented into UDEC, which is compared in Figure 5 with the analytical solution.
In general, the results from UDEC with the TDRW method implemented agreed well with the analytical solution.
From the comparisons shown in Figures 5 and 7, it is concluded that the numerical solution obtained using the TDRW method implemented into UDEC was close to the analytical solution.
Aiming at solving these problems, the time-domain random-walk (TDRW) method was firstly implemented into the discrete element method (DEM) in this study.
(1) The implementation of the TDRW method into UDEC could well simulate the nuclide transport with underground water in fractured rock masses.

Symmetric decompositions of cost variation
European Journal of Operational Research, Volume 285 p. 1189- 1198
In this paper a number of symmetric, empirically implementable decompositions of the cost variation (in difference and ratio form) of a production unit are developed. The components distinguished are price level change, technical efficiency change, allocative efficiency change, technological change, scale of activity change, and price structure change. Given data from a (balanced) panel of production units, all the necessary ingredients for the computation of the various decompositions can be obtained by using linear programming techniques (DEA). An application is provided.

What is known as "one-to-nearest" addressing in IPv6?
Click on the arrows to vote for the correct answerA. B. C. D.
In IPv6 addressing, "one-to-nearest" addressing refers to a type of address allocation where a single IPv6 address is assigned to a device, but that address is not necessarily unique on the network. This type of addressing is known as "anycast" addressing.
Anycast addressing allows multiple devices to share a single IPv6 address, but packets addressed to that address are only delivered to the nearest device in the group. This is achieved through the use of routing protocols that determine which device is the nearest and route packets accordingly.
Anycast addresses are used for specific purposes in IPv6, such as for services that need to be highly available and distributed across multiple locations. For example, a DNS server might use anycast addressing so that queries are automatically routed to the nearest available server, improving response times and reducing network latency.
In contrast to anycast addressing, "global unicast" addressing refers to the allocation of unique IPv6 addresses to individual devices. Global unicast addresses are used for normal communication between devices on the network, and are routable across the entire Internet.
The "unspecified address" in IPv6 is a special address used to indicate the absence of an address, similar to the IPv4 address 0.0.0.0.
Finally, "multicast" addressing in IPv6 is used to send packets to a group of devices on the network that have joined a specific multicast group. This is typically used for applications such as video conferencing, online gaming, and other real-time multimedia applications.

Using data from every mouse click a student makes doing online course work, researchers from three University of Wisconsin institutions hope to identify students at risk of doing poorly and potentially dropping out of school.
The goal of the project by the University of Wisconsin Colleges, UW-Madison and UW-Platteville is to help more students succeed.
The project is funded by a three-year grant worth about $650,000. The grant comes from the UW System, which spends about $2 million annually on grants aimed at improving retention and graduation rates, according to Mark Nook, the system's senior vice president for academic and student affairs.
Using principles similar to those that Amazon.com uses for book recommendations, a computer program will track students' activity during online course work, looking at things such as how long a person is logged on, how much time is spent on particular problems and whether discussion boards are being used, said Aaron Brower, UW-Madison vice provost for teaching and learning.


text: This study describes a novel experimental approach to directly measure the thicknesses of asphaltene deposits in micro-channels. The thickness of the asphaltene deposit is estimated using a visualization technique based on 3D digital microscopy. The working fluid is a mixture of n-heptane and dead oil. Induced by the addition of n-heptane, the asphaltenes present in crude oil phase separate at ambient temperature to form aggregates of asphaltene-rich phase. Part of the asphaltene aggregates deposit on the walls of the transparent micro-channel. A two-dimensional profile of the deposit across the channel at selected axial sections is measured. The influences of injection mixture volume on the growth of the thickness of deposited asphaltenes is investigated using two experimental conditions, (i) varying elapsed time at constant flow rate and (ii) increasing the flow rate at a constant elapsed time. In both cases the deposit thickness of asphaltene (δ) increases with the total injection volume (V). The experimental results obtained in this work provide new insights into the deposition process at the micro-scale level, which can be used to facilitate the development of more accurate numerical model for this application.

Under preemptive scheduling, the highest priority task executes until it enters the waiting or dead states or a higher priority task comes into existence.
Under time slicing, a task executes for a predefined slice of time and then reenters the pool of ready tasks. The scheduler then determines which task should execute next, based on priority and other factors.

If you're a backpacker you need a reliable yet lightweight method for purifying and filtering water in the wild. Most commercial methods are either bulky and heavy or need supplies such as salt and/or batteries. Instead you can make a gravity water filtration system using two water bladders, a $17 Aquamira Frontier Pro filter or likewise, and a pack of chlorine dioxide purification tablets.
YouTube user and veteran backpacker Jason Klass demonstrates the light weight, versatility, and low cost (around $40 for everything) of this setup. Basically you fill your "dirty" water bottle directly from a river, lake, or stream, add a purification tablet, and connect your clean water bottle to the Aquamira filter. The other side of the filter is connected to the water resevoir you drink from. Hang the dirty water from a tree branch and keep the clean water on the ground and in half an hour you'll have a couple of liters of clean water to drink.
Why does this system use both a chemical and a mechanical filter? The aquamira filter is good at keeping out dirt and objects that would change the taste of your water but does not filter closely enough to remove most bacterias and viruses. A chlorine dioxide chemical treatment (same as what most municipal water supplies use) will kill 99.999% of all viruses and bacterias and shouldn't change the taste of the water. If you run out of purification tablets while on the trail you can always gravity filter the water into a pot and boil it.


Self-reinforcing Mechanisms in a Multi-technology Industry: Understanding Sustained Technological Variety in a Context of Path Dependency
Artikel i vetenskaplig tidskrift, 2015
This paper studies self-reinforcing mechanisms in multi-technology industries, i.e. industries in which technological lock-in does not occur and several technologies continue to coexist. The purpose of this paper is to investigate what kind of self-reinforcing mechanisms can be present in such industries and explain how multiple paths can coexist and interact in a context of self-reinforcement and, ultimately, path dependency. Building on the empirical example of the lighting industry, the paper shows that all previously recognized types of self-reinforcing mechanisms can be present in a multi-technology industry. However, in addition to the path-internal positive feedbacks and cross-path negative externalities identified in single-path settings, multi-technology industries also experience positive cross-path externalities that create a symbiotic relationship between alternatives and allow for the reproduction of the same development pattern across technologies. Due to the existence of such non-negative technology interactions, multi-technology industries can be path dependent while still retaining technological variety.

There are any number of winemakers throughout the world that choose to build eccentric wines, wines that are atypical of wines from their regions and countries.
The first Super Tuscans — wines made in Tuscany from Cabernet Sauvignon and Merlot, designed to cater to the American market — were such wines. To accommodate such experimentation, wine countries around the world are creating specific classes of appellations to allow for improvement and the peculiarities of the winemakers.
tap here to see other videos from our team.
The first country to do so was Italy, which brought in Goria's Law in the '90s. Signor Goria, Italy's then-Minister of Agriculture, did something radical and created the Idicazione Geografica Tipica classification. He accepted that historically Italians had planted any number of varietals and made wine from them, albeit atypical for the DOC.
The freedom to experiment proved popular and other wine producing countries from Portugal to France and beyond are adopting similar designations.


Introduction
PostgreSQL, also referred to as Postgres, is an open-source, object-relational database management system. Developers often opt for this relational database as it is free, stable, and flexible. In fact, PostgreSQL and MySQL are the most popular Relational Database Management Systems.
Today, Postgres is one of the most widely used Docker images that run in containers. The popularity of containerized databases is attributed to the simplicity with which they can be deployed. Also, instead of having one centralized database for many applications, developers can devote a PostgreSQL container for each application.
In this tutorial, you will learn how to run PostgreSQL on a Docker container.
Tutorial on how to run PostgreSQL in a Docker container.
Prerequisites
 - Access to a command line/terminal window
 - A user account with sudo privileges
 - An existing Docker installation
Running PostgreSQL on Docker Containers
Deploying a Postgres container is simple. You can find the Postgres image for building these database containers in Docker's official repository.
This guide shows you two ways to do so.
The first option uses Docker Compose, a tool for managing multi-container Docker applications. You can use Docker Compose to configure the Postgres as a service running inside of a container. In that case, you create a yaml file with all the specifications.
Alternatively, you can use a single Docker command with all the necessary information for deploying a new PostgreSQL container.
Option 1: Run Postgres Using Docker Compose
To deploy a Postgres container using Docker Compose, you should have this Docker tool set up on your system.
If you are a Linux user and need help setting up, refer to one of our guides on installing Docker Compose on Ubuntu or how to install Docker Compose on CentOS.
1. To ensure an easy and clean installation, we first want to create a working directory named postgres and move into that directory:
mkdir postgres
cd postgres/
2. Next, use Docker Compose to download the Postgres image and get the service up and running. Do this by creating a new docker-compose.yml file with an editor of your choice (in this example, we used nano):
nano docker-compose.yml
3. Add the following content to the docker-compose file:
version: '3'
service:
 postgres:
 image: 'postgres: latest'
 ports:
 - "5432:5432"
The yaml configuration file outlines there is a postgres service, built on the latest postgres image. You can decide on the newest Postgres version or specify the version number you want to use.
Finally, you need to define the ports on which the container communicates. 5432 is the default port number for PostgreSQL.
4. Save and exit the file.
5. Now that you have the yaml configuration file, you can start the postgres service and run the container. Use the docker-compose up command with the -d option to put it into detach mode (allowing you to continue to run commands from the current shell):
docker-compose up -d
6. You can check the logs with the command:
docker-compose logs -f
To return to the shell press CTRL+C.
Option 2: Run Postgres Using a Single Docker Command
Another way to deploy PostgreSQL in a container is by running a single docker command.
You can download and run a Postgres container by specifying all the necessary information in one command.
docker run --name [container_name] -e POSTGRES_PASSWORD=[your_password] -d postgres
The command tells Docker to run a new container under a particular container name, defines the Postgres password, and downloads the latest Postgres release.
Confirm your PostgreSQL container is now up by prompting Docker to list all running containers with:
docker ps
In this guide, we created a container named example and we can quickly locate it among other running containers.
A single command for deploying Postgres in a Docker container.
Starting with Postgres Containers
Connect to Postgres in Docker Container
To enter a Postgres container, you need to execute using the container name and enable psql, the command-line interface for Postgres.
docker exec -it [container_name] psql -U [postgres_user]
In the example below, we connected to the example container as the postgres user.
Command for connecting to Postgres in a Docker container.
Create a Database
Once in the Docker Postgres container, we can create a database with:
create database [db_name];
Note: To view all the databases you have running on PostgreSQL run: \l.
Connect to the database as the postgres user type:
\c [db_name]
With the database set up, the next step is to create a schema that helps you get a logical representation of the database structure:
create schema [db_schema_name]
Here you can create a table and add data into the table.
create table [table_name] ([field_names] [values])
Note: If you want to exit the Postgres container, type in the following: \q.
Conclusion
In this article you learned two different ways to run a PostgreSQL in a Docker container. After deploying a Docker Postgres container, you can start creating your databases with all the data required.
Deploying PostgreSQL in a container is cost-efficient in terms of infrastructure, it also supports CI/CD development, and streamlines deployment and application management.

A credit card for those who do not have a formal contract may seem far from reachable, since most financial institutions ask for proof of income. However, if you don't have a formal contract, you can have a credit card.
In this post you will find out everything you need to get your credit card without having a formal contract, in addition to knowing bank options for those who are in this situation.
What this article covers:
Where to get a credit card without having a signed wallet?
Different from what some people think, nowadays it is possible to get your credit card for those who don't have a formal contract.
This is because financial institutions care more about other issues, not just proof of income, such as a clean name on Serasa or SPC, in addition to your Score, which is linked to your financial transactions.
Some traditional banks offer credit cards for those who do not have a formal contract, especially for those who are just starting out in life now, such as university students. And many digital banks also allow you to have a credit card without having a signed wallet.
Why do credit cards ask for confirmed income?
This proof of income occurs because the banks need to confirm that the person who applied for the credit card will be able to make the payment later, so it is a way for the financial institution to have some type of protection.
How do I earn the proven influence on the credit limit?
Your income will be directly linked to the credit limit offered by the financial institution. This is because banks, for the most part, use proof of monthly income to define the customer's limit.
Options without a signed wallet or proof of credit
The time has come to learn about the options for those looking for a credit card without having a formal contract or other type of proof. We separate the ones that are considered better by customers and that approval is not so difficult.
college credit card
Those who are university students and are looking for a credit card, but have no way of proving their income, this is the option. The main banks in the country offer this opportunity to their customers, however, it is necessary to have an account in order to apply for the card.
In addition, you also need to confirm that you are at the university through proof of enrollment. The credit card options are as follows:
- BB Young;
- Bradesco Universitário;
- University Santander;
- Itaú University;
- Caixa Universitario;
- University Ourocard.
If you already have an account at one of these banks, it will be the best choice for your university credit card.
Credit card in digital banks
Another way to get your credit card for those who don't have a formal contract is through digital banks, since most don't ask for proof of income.
However, some of these banks will do analysis, which does not guarantee that you will get the credit card on the first try. The most famous banks in this modality are:
- Banco Inter;
- Pan Bank;
Most credit card applications at these banks occur through the bank's app or website. So just enter, fill in the requested information and wait for the bank to return, informing you if you were approved or not.
It is worth noting that most of these banks also do not require you to have a digital bank account, which turns out to be a good differentiator.
store credit card
Some stores also offer the opportunity for you to make a store card, which can often be used in other establishments and it is not necessary to prove income. You can do this in stores like Saraiva, C&A and Casas Bahia. But it should be noted that these stores carry out an analysis before approval.
Prepaid cards have become another option that does not require proof of income. In this type of card, you deposit money and use it later to pay your bills. However, it is not possible to have a credit limit or to pay your purchases in installments, being possible to spend only what is available on the card.
Can I check income without having a formal contract?
Yes, it is possible to carry out income verification without having a formal contract.
This can be done in three ways: becoming a MEI, with the presentation of the tax return and by issuing the DECORE.
How it works?
To do this as a MEI (Individual Microentrepreneur) just present the Invoices issued. They will be used as proof of income.
When filing your income tax return, you can prove that you are able to maintain a monthly and annual income that allows you to have a credit card. However, not all financial institutions accept only the income tax return, other documents can be requested.
Finally, you can issue the DECORE (Proofing Statement of Income Perception), which is a statement made by a registered accountant, thus proving that you have a monthly income. This request can be made over the internet, the accountant will only need some of your data to carry it out.
Therefore, there are varied options for those who wish to have a credit card for those who do not have a formal contract. Digital banks can be considered the most common, however, if you prefer a traditional financial institution, using one of the aforementioned ways to prove income without a formal contract can be very useful.

calendarDropTarget calendar drop target
This tag makes a calendar component a drop target and can be used to declaratively initialize the drop target.
Name Type Supports EL? Description
actions String no Drag and drop actions supported by this target. The actions must be an NMTOKENS from the set of "COPY, "MOVE", "LINK" in any particular order e.g. (actions="COPY LINK MOVE"). If no actions are specified, the default is "COPY".
dropListener javax.faces.el.MethodBinding Only EL A method reference to a callback with the signature method( dropEvent) called when a drop occurs on the component. This callback should check the DropEvent to determine whether it will accept the drop or not. If the callback accepts the drop, it should perform the drop and return the DnDAction it performed-- DnDAction.COPY, DnDAction.MOVE or DnDAction.LINK, otherwise it should return DnDAction.NONE to indicate that the drop was rejected. The target component is automatically redrawn in response to a successful drop.
If the calendarDropTarget is attached to the calendar component, an implicit support for moving of activities is added by the framework. The drop transferable will contain the object of the following flavor: The dropSite for the drop event will be an object of instance:
Please note that currently there is no CalendarDragSource tag and hence the drop target is responsible for moving the activities. Page authors are responsible for handling drop from external data sources in dropListener. This can be done by adding one or more af:dataFlovor tags to the af:calendarDropTarget tag.
