Overview
Frequently used constants when constructing requests or responses. Many times the constant just refers to a string with the same contents. Using these constants gave about a 3% to 10% performance improvement over using the strings directly.
The constants are frozen because Hash#[]=
when called with a String key dups the String UNLESS the String is frozen. This saves us therefore 2 object allocations when creating the env hash later.
While Puma does try to emulate the CGI/1.2 protocol, it does not use the REMOTE_IDENT, REMOTE_USER, or REMOTE_HOST parameters since those are either a security problem or too taxing on performance.

PureBasic - Gadget3D
概要
The Gadget3D library allows to create complex Graphical User Interface (GUI) directly over the screen area, using the 3D engine. This is mainly intended for game or application which needs user inputs while running in fullscreen mode. This library is based on the regular PureBasic gadget library, and offer similar syntax and behavior. The GUI engine used is CEGUI, which offer some nice options like skinning, good speed and a lot of built-in gadgets. More information about CEGUI can be found here: http://www.cegui.org.uk.
It uses the 3D engine, so InitEngine3D() has to be called successfully before using these functions.
Before using gadgets there will be normally opened a window first.

A review by John Beachem

CAST Robert DeNiro - Sam Jean Reno - Vincent Stellan Skarsgard - Gregor Natascha McElhone - Dierdre
After watching this film, I sat back and realized I'd been on the edge of my seat the entire time, and my hands were gripping the armrests. Looking back on this, I can't for the life of me figure out what it is about this particular movie that so engrossed me.
Ronin are samurai who have no master. Modern Ronin appear to be men trained in arts such as espionage, assassination, and combat who have no country to serve. Therefore, they choose to line their own pockets. Five such men are hired by an irish woman who goes only by the name of Dierdre. They are hired to steal a silver briefcase from a band of men, and deliver it to her. The plan hardly goes off without a hitch since none of the men trust each other. One of them grabs the case for himself with the intent of selling it to the highest bidder. The remaining men, led by Sam go after him in an attempt to get the case, and thus their money.
Let me say right now, that I'm not entirely sure how to go about reviewing this film. It sounds like so many other typical action movies, complete with some great looking car chases and a whole lot of explosions. However, there is something strangely different about this one. More enthralling. I'm sure part of the movie's charm is the presence of DeNiro and Reno, two wonderful actors. There is nothing even remotely resembling character development, but this strangely adds to the story. It makes these men more mysterious and dangerous.
A lot of things are never adequately explained, such as why the group is attacked in one of the first scenes involving them, and to warn everyone right now, we never discover the contents of the much sought after case. Also worth noting, Stellan Skarsgard is quite good as the cold blooded Gregor, but there is an early scene in which he demonstrates his amazing reflexes for no apparent reason since we never see them used in the rest of the film.
So, a few pointless scenes are present, but the majority of the film is quite well done, and the car chases are enthralling. For some great action, good acting, and a rather bizzare plot, Ronin earns four stars.
* * * * * - One of the greatest movies ever made, see it now. * * * * - Great flick. Try and catch this one. * * * - Okay movie, hits and misses. * * - Pretty bad. See it if you've got nothing better to do. * - One of the worst movies ever. See it only if you enjoy pain.

'Perfect' Remembrance Day as war medals returned to family
by Kathy Rumleski, Web JournalistLONDON, Ont. -- It’s been a Remembrance Day Shawn MacNeil will not forget.
His mission was to hand deliver three First World War medals to Bayfield and to the family of a soldier who served in the 1st Canadian Infantry.
“It couldn’t be a more perfect Remembrance Day,” MacNeil says while driving from Corunna to Bayfield in snowy conditions to hand over the medals.
“This is my mandate.”
MacNeil is a Veteran Service Officer for the Royal Canadian Legion, Branch 447 in Corunna. It was at that branch that a lady dropped off a Laura Secord chocolate box that contained war memorabilia, including shoulder flashes and empty bullet cases, along with the medals.
The three medals are the British Victory Medal, the Canadian Victory Medal and Great War for Civilization Medal.
Each has the name Ernest Henry Bake and his service number. Bake’s attestation papers show he was 27 when he signed them on Sept. 14, 1914 in Halifax, N.S.
After posting photos of the medals on Facebook, Legion members went to work sharing the post and trying to find the Bake family. A Ladies Auxiliary member did some research using her Ancestry account.
About two weeks after the post, MacNeil was contacted by the Bayfield Historical Society who had two uniforms of Bake’s son Leslie Bake in their possession for a Remembrance Day display.
Leslie served in World War II in France, Belgium and Holland.
The granddaughter of Ernest Bake, Margaret Clydesdale, was on hand for a presentation of the medals from MacNeil Monday afternoon in Bayfield, along with members of the Bayfield Historical Society.
When seeing the medals for the first time in decades, Clydesdale was choked up. "It's amazing; I'm overwhelmed."
She is unsure how the medals turned up in Corunna.
MacNeil, who is originally from London and is a Laurier Secondary School graduate, says it feels “extremely rewarding” to know the medals are back with the family.
“Every time I think about it, even now, I still get chills up and down my spine. These medals are precious. For me as a service officer, this is very fulfilling. This is my mandate.”
He is also particularly excited that the medal presentation was in front of the Remembrance Day windows at the Bayfield Historical Society and with Leslie’s uniforms on hand.
“That blew my mind. When I got them (the medals), I thought, ‘If I can re-unite them on or before Remembrance Day.’ It came to fruition. It’s an absolute honour to be able to reunite them with the family.”
MacNeil will also be in London on Remembrance Day to deliver a cheque from the Ladies’ Auxiliary at his branch to provide funds for veteran beds at Parkwood Institute.

A. GS1 Related
1. The boycott ban: on Maharashtra’s law against social boycott
Context
- Maharashtra’s new law prohibiting the social boycott of individuals, families or any community by informal village councils is a step in the right direction, given the pervasive nature of the problem.
- The progressive legislation, which received Presidential assent recently and was gazetted earlier this month, targets the pernicious practice of informal caste panchayats or dominant sections using ostracism as a means of enforcing social conformity.
The Maharashtra Protection of People from Social Boycott (Prevention, Prohibition and Redressal) Act, 2016
- The act may serve as a template for similar legislation in other States.
- The Act lists over a dozen types of actions that may amount to ‘social boycott’, which has been made a criminal offence punishable with imprisonment up to three years or a fine of Rs. 1 lakh or both.
- The practices it prohibits range from preventing the performance of a social or religious custom, denial of the right to perform funerals or marriages, cutting off someone’s social or commercial ties to preventing access to educational or medical institutions or community halls and public facilities, or any form of social ostracism on any ground.
- The law recognizes the human rights dimension to issues of social boycott, as well as the varied forms in which it occurs in a caste-based society.
- Its progressive sweep takes into account discrimination on the basis of morality, social acceptance, political inclination, sexuality, which it prohibits. It even makes it an offence to create cultural obstacles by forcing people to wear a particular type of clothing or use a particular language.
Previous instances
- This is not the first law of its type. Bombay enacted a law against excommunication in 1949, but it was struck down by the Supreme Court in 1962 after the Dawoodi Bohra community successfully argued that it violated the community’s constitutional right to manage its own religious affairs.
Article 17
- One hopes the latest Act will not be vulnerable to legal challenge. Article 17 of the Constitution and the Protection of Civil Rights Act outlaw untouchability in all its forms, but these are legal protections intended for the Scheduled Castes.
- In reality, members of various castes and communities also require such protection from informal village councils and gatherings of elders who draw on their own notions of conformity, community discipline, morality and social mores to issue diktats to the village or the community to cut off ties with supposedly offending persons and families.
The inhuman practice of social boycott
- The case of a mountaineer from Raigad is somewhat notorious. He had conquered Mt. Everest but could not escape a social boycott in his village because his wife wore jeans and did not wear a mangalsutra.
Conclusion
- It is not a proud moment for a country when special legislation is required to prohibit social discrimination, ostracism and practices repugnant to human dignity. Yet, given the prevailing circumstances, any legislative assault on abhorrent social practices ought to be welcomed.

1. Ordinances should be last resort: Pranab
Context
- Bidding farewell to Parliament at a function to mark the end of his tenure, President Pranab Mukherjee said here on Sunday that the institution was for “debate, discussion and dissent.” Disruptions, he said, hurt the Opposition as it took away from it the opportunity to raise people’s concerns.
The president had a word of advice for the government too
- Ordinances should be resorted to only in “compelling circumstances.”
- The President’s remark is significant as the Modi government, after repeatedly failing to amend the Enemy Property Act, 1968 in the last three years, had promulgated five ordinances. The Bill was passed by Parliament in March. Senior Union Ministers were reportedly deputed to convince the President to sign the fourth and fifth Enemy Property ordinances as he was against their promulgation.
The passage of the GST Bill
- The passage of the GST Bill was a sign of Parliament’s maturity. Its launch on July 1 was a shining example of cooperative federalism.
- Values like fraternity, dignity and unity had become the lodestar for the country since Independence.
Ordinance making powers of the Executive in India
The Ordinance will only be promulgated after it receives the assent of the President.
I. Separation of powers between the Legislature, Executive and Judiciary
- In India, the central and state legislatures are responsible for law making, the central and state governments are responsible for the implementation of laws and the judiciary (Supreme Court, High Courts and lower courts) interprets these laws.
- However, there are several overlaps in the functions and powers of the three institutions. For example, the President has certain legislative and judicial functions and the legislature can delegate some of its functions to the executive in the form of subordinate legislation.
II. Ordinance making powers of the President
- Article 123 of the Constitution grants the President certain law making powers to promulgate Ordinances when either of the two Houses of Parliament is not in session and hence it is not possible to enact laws in the Parliament.
- An Ordinance may relate to any subject that the Parliament has the power to legislate on. Conversely, it has the same limitations as the Parliament to legislate, given the distribution of powers between the Union, State and Concurrent Lists. Thus, the following limitations exist with regard to the Ordinance making power of the executive:
-
- Legislature is not in session: The President can only promulgate an Ordinance when either of the two Houses of Parliament is not in session.
- Immediate action is required: The President cannot promulgate an Ordinance unless he is satisfied that there are circumstances that require taking ‘immediate action’.
- Parliamentary approval during session: Ordinances must be approved by Parliament within six weeks of reassembling or they shall cease to operate. They will also cease to operate in case resolutions disapproving the Ordinance are passed by both the Houses.
III. Ordinance making powers of the Governor
- Just as the President of India is constitutionally mandated to issue Ordinances under Article 123, the Governor of a state can issue Ordinances under Article 213, when the state legislative assembly (or either of the two Houses in states with bicameral legislatures) is not in session. The powers of the President and the Governor are broadly comparable with respect to Ordinance making. However, the Governor cannot issue an Ordinance without instructions from the President in three cases where the assent of the President would have been required to pass a similar Bill.
IV. Key debates relating to the Ordinance making powers of the Executive
- There has been significant debate surrounding the Ordinance making power of the President (and Governor). Constitutionally, important issues that have been raised include judicial review of the Ordinance making powers of the executive; the necessity for ‘immediate action’ while promulgating an Ordinance; and the granting of Ordinance making powers to the executive, given the principle of separation of powers.
Table 1 provides a brief historical overview of the manner in which the debate on the Ordinance making powers of the executive has evolved in India post independence.

In RC Cooper vs. Union of India (1970) the Supreme Court, while examining the constitutionality of the Banking Companies (Acquisition of Undertakings) Ordinance, 1969 which sought to nationalise 14 of India’s largest commercial banks, held that the President’s decision could be challenged on the grounds that ‘immediate action’ was not required; and the Ordinance had been passed primarily to by-pass debate and discussion in the legislature. |
|
1975 |
38thConstitutional Amendment Act |
Inserted a new clause (4) in Article 123 stating that the President’s satisfaction while promulgating an Ordinance was final and could not be questioned in any court on any ground. |
|
1978 |
44thConstitutional Amendment Act |
Deleted clause (4) inserted by the 38th CAA and therefore reopened the possibility for the judicial review of the President’s decision to promulgate an Ordinance. |
|
1980 |
AK Roy vs.Union of India |
In AK Roy vs. Union of India (1982) while examining the constitutionality of the National Security Ordinance, 1980, which sought to provide for preventive detention in certain cases, the Court argued that the President’s Ordinance making power is not beyond the scope of judicial review. However, it did not explore the issue further as there was insufficient evidence before it and the Ordinance was replaced by an Act. It also pointed out the need to exercise judicial review over the President’s decision only when there were substantial grounds to challenge the decision, and not at “every casual and passing challenge”. |
|
1985 |
T Venkata Reddy vs.State of Andhra Pradesh |
In T Venkata Reddy vs. State of Andhra Pradesh (1985), while deliberating on the promulgation of the Andhra Pradesh Abolition of Posts of Part-time Village Officers Ordinance, 1984 which abolished certain village level posts, the Court reiterated that the Ordinance making power of the President and the Governor was a legislative power, comparable to the legislative power of the Parliament and state legislatures respectively. This implies that the motives behind the exercise of this power cannot be questioned, just as is the case with legislation by the Parliament and state legislatures. |
|
1987 |
DC Wadhwa vs. State of Bihar |
It was argued in DC Wadhwa vs. State of Bihar (1987) the legislative power of the executive to promulgate Ordinances is to be used in exceptional circumstances and not as a substitute for the law making power of the legislature. Here, the court was examining a case where a state government (under the authority of the Governor) continued to re-promulgate ordinances, that is, it repeatedly issued new Ordinances to replace the old ones, instead of laying them before the state legislature. A total of 259 Ordinances were re-promulgated, some of them for as long as 14 years. The Supreme Court argued that if Ordinance making was made a usual practice, creating an ‘Ordinance raj’ the courts could strike down re-promulgated Ordinances. |
2. Bengaluru Declaration calls for SC/ST quota in judiciary
- The Bengaluru Declaration adopted by the State government sponsored Dr. B.R. Ambedkar International Conference 2017, on Sunday recommended a slew of affirmative action measures in private sector, judiciary, educational institutions, government contracts and promotions for Dalits.
The Bengaluru Declaration
- The declaration, coming in an election year, significantly concentrates not just on SC/STs, but has also proposed several measures for the larger AHINDA (Kannada acronym for minorities, backward classes and Dalits) community, the political constituency of Chief Minister Siddaramaiah.
- It called for reservation of seats in legislature for other backward classes and setting up of a farmers’ income commission.
- The eight-page declaration has 40 recommendations under six broad categories — safeguarding the people, strengthening democratic institutions, deepening social justice, enhancing human development, ensuring responsive governance, and promoting social security.
- “This Peoples’ Declaration hopes to be a dynamic blueprint that addresses the needs and aspirations of all Indians, and a starting point for an ‘alliance of equity’ of all progressive forces committed to safeguarding the idea of India,” the preamble stated.”
- The Bhopal Declaration that called for “liberalisation of capital for Dalits” was adopted in 2002 during the tenure of Congress leader Digvijaya Singh in Madhya Pradesh.
- Significantly, the Bengaluru Declaration called for upholding Rule of Law through police reforms and state action to prevent lynchings. It called for a law against gender and caste discrimination at education institutions.
- It further recommended for SC/ST reservation in appointment of judges, promotions, government contracts up to ₹1 crore, in private higher educational institutions and private s It also proposes establishment of an Equal Opportunities Commission, to oversee affirmative action.
- Much focus is also given on ensuring land ownership for SC/STs, including a proposal to establish SC/ST land bank, where government buys these lands at market prices and re-allots to the same community, to ensure non-dilution of ownership. It further recommends allocation of 20% of the land in private housing layouts for urban poor.
- The declaration calls for a wider social security net. It recommended a “living wage” and comprehensive social security scheme for all labourers working in the unorganised sector apart from ensuring dignity in retirement through enhanced pensions of ₹1,500 per month.
3. CAG flags delay in work on corvettes
In news
- The Comptroller and Auditor-General (CAG) has faulted the Navy and Garden Reach Shipbuilders and Engineers Ltd. for delay in construction of anti-submarine warfare corvettes and hampering their capabilities because of delayed decisions.
Weapons not installed
- In the report presented in Parliament last week, the CAG said, “Against the 18 weapons and sensors to be installed on ASW corvettes, audit observed that the two ASW corvettes delivered were not fitted with ‘X’ weapon and sensor systems. Thus, ASW corvettes could not perform to its full potential as envisaged.”
1. MPC members to get Rs.1.5 lakh per meet, must disclose assets
- The government appointees on the powerful Monetary Policy Committee will be paid Rs.5 lakh per meeting along with air travel and other reimbursements, but will need to observe a “silent period” seven days before and after the rate decision for “utmost confidentiality”.
- The silent period and confidentiality requirements will also apply to the three RBI members, including the Governor, on the panel that has been deciding on policy rates since October last year, the central bank has said.
‘Conflict of interest’
- The Reserve Bank released its newly notified regulations for functioning of the committee.
- The members of the RBI Governor-chaired panel, which has to hold meetings at least four times in a year, are also required to be mindful of any conflict between their personal and public interest while interacting with profit making organisations and making personal financial transactions
Monetary Policy Committee
- The six-member MPC, constituted in September 2016, has three persons appointed by the central government while the rest, including the Governor, are from the RBI.
- The panel is required to meet at least four times in a year and the RBI has been convening a bi-monthly meeting of this committee.
- According to the Monetary Policy Committee and Monetary Policy Process Regulations, 2016, MPC members should also take adequate precaution to ensure utmost confidentiality of its policy decision before that is made public and preserve confidentiality about the decision making process,
- Each member of the MPC has one vote and in case the numbers are equal, the governor has the casting vote.
- The MPC, which has the responsibility of achieving a set inflation target, should submit a report to the government in case of failure to achieve the required target.
- In such instances, the report shall be sent to the central government “within one month from the date on which the bank has failed to meet the inflation target“.
Annual disclosure
- All members need to disclose their assets and liabilities and update this information once every year.
- Also, members cannot reveal outside the committee any confidential information accessed during the monetary policy deliberations.
- After conclusion of MPC meeting, a resolution needs to be made public including on the policy repo rate and any other monetary policy measures at the discretion of the Chairperson while keeping in view the functioning and timing of financial markets.
1. Once hero, now ‘white elephant’
In news
- Decommissioned submarine Vagli lies idle in Chennai port after plan to convert it into a museum fails.
- She served the Indian Navy and the nation for over 36 years and could have become only the second submarine museum of the country. But since her decommissioning in 2010, the Russia-designed submarine INS Vagli has taken a tedious and uncertain course. She currently lies idle at the Chennai port.
- The submarine, which was to be the centrepiece of the maritime heritage museum planned by the Tamil Nadu government in the tourist town of Mamallapuram, was expected to be displayed on a 30-acre stretch of land near the Shore Temple of the UNESCO-declared World Heritage group of monuments.
- However, the inability of a contractor to mount the submarine on the intended site at Mamallapuram has forced the vessel to lie idle at the Chennai port.
‘Wasteful expenditure’
- A 2016 report of the Comptroller and Auditor General (CAG) of India questioned the process adopted by the government to move the submarine to Mamallapuram in one piece and observed that an “infructuous expenditure of Rs. 4.41 crore” was incurred due to a lack of proper planning.
- In December 2016, the submarine was almost damaged when Cyclone Vardah hit the Chennai coast.
INS Vagli
- INS Vagli was commissioned into the Indian Navy at Riga in Latvia, which was part of the erstwhile Soviet Union in 1974, and was decommissioned at Visakhapatnam in December 2010.

In this form of attack, the adversary is free to choose the plaintext which will be encrypted. From the known-plaintext-encrypted text pair, he then attempts to work out the key that has been used.
In a known-plaintext attack, only one arbitrary plaintext-encrypted text pair is known.
By contrast, for a ciphertext-only attack knowledge of the plaintext is not necessary.

Does "participatory sensory mapping": what do you do with this data you can gather, how do you turn it into a political proposition? What are the tools we can use to rethink the space?
He blindfolds children and has them led along by someone else, using other senses (smell, etc.) for local area. Produces a sensory deprivation map, a set of experiences geolocated: beautiful. 50% of categorisations are negative, 22% neutral, 28% positive.
Turns this into getting kids involved with local politics: there's a road in front of the school full of traffic and smells.
Next project: lie detector + GPS unit, to create emotion maps. Tends to do these in areas of regeneration - e.g. Stockport. PDAs are good, but physical paper maps are nice because you can stand around them: they talk in a language people can understand.
Really really nice looking stuff :)

 Once again, you are bored because your teacher tells things that you already mastered years ago (this time he’s explaining that (a+b)2=a2+2ab+b2).
Really a masterpiece, isn’t it? Repeating the procedure one more time, you arrive with the picture shown on the right. Now you wonder: how many different works of art can you produce?
Fortunately you have a piece of squared paper and you choose a rectangle of size n*m on the paper. Let’s call this rectangle together with the lines it contains a grid. Starting at the lower left corner of the grid, you move your pencil to the upper right corner, taking care that it stays on the lines and moves only to the right or up. The result is shown on the left:
Really a masterpiece, isn’t it? Repeating the procedure one more time, you arrive with the picture shown on the right. Now you wonder: how many different works of art can you produce?
输入:
The input contains several testcases. Each is specified by two unsigned 32-bit integers n and m, denoting the size of the rectangle. As you can observe, the number of lines of the corresponding grid is one more in each dimension. Input is terminated by n=m=0.
输出:
For each test case output on a line the number of different art works that can be generated using the procedure described above. That is, how many paths are there on a grid where each step of the path consists of moving one unit to the right or one unit up? You may safely assume that this number fits into a 32-bit unsigned integer.

int L[m+1][n+1];这样定义出错，这个在gcc上可以编译通过 在VS上不行 应该改为new 或者vector
第15行代码，/n/n，应该改为\n\n
swap写成内联函数会不会好一些
.net中char类型不是两个字节么
第一种方法怎么会是O(log(m+n))呢？没有二分的话直接遍历应该就是O(m+n)吧？

This is where a component has is a blend of one or more of Constructor, Setter, Method, Annotated Field etc:
public class Apple { private Orange orange; private Pear pear; @Inject private Banana banana; public inject(Orange orange) { this.orange = orange; } public void inject(Pear pear) { this.pear = pear; } // other methods }
pico = new DefaultPicoContainer(new MultiInjection(); pico.addComponent(Apple.class); // etc Apple apple = pico.getComponent(Apple.class);
In the case above, Orange comes in through the constructor, Pear by method injection and Banana is via Annotated Field Injection.
The component factory for this is MultiInjection.

Gremlin is a graph traversal language developed by TinkerPop. Faunus’ Gremlin steps are implemented in MapReduce. For sake of clarity, the Gremlin that compiles down to Pipes and is used for real-time traversals against a graph database is denoted Gremlin/Pipes. The Gremlin that is distributed with Faunus and compiles down to MapReduce is denoted Gremlin/Faunus.
There are major conceptual differences between Gremlin/Pipes and Gremlin/Faunus. These differences are itemized below.
The table below presents the steps provided with Gremlin/Faunus.
| Gremlin/Faunus step | Description | Reduce? |
|---|---|---|
| transforms | ||
_ |
the identity step that simply updates Hadoop counters | false |
transform(closure) |
evaluate the closure on current elements | false |
V |
start a traversal at all vertices | false |
E |
start a traversal at all edges | false |
v(id..) |
start a traversal at vertices with provided id | false |
out(labels..) |
traverse out from vertices to label-related vertices | true |
in(labels..) |
traverse in from vertices to label-related vertices | true |
both(labels..) |
traverse both directions from vertices to label-related vertices | true |
outE(labels..) |
traverse from vertices to outgoing label edges | true |
inE(labels..) |
traverse from vertices to incoming label edges | true |
bothE(labels..) |
traverse from vertices to in and out label edges | true |
outV |
traverse from edges to outgoing vertices | false |
inV |
traverse from edges to incoming vertices | false |
bothV |
traverse from edges to both in and out vertices | false |
property(key,class?) |
emit element property values (class? for optimization) | false |
path |
emit the path taken up to the current elements | false |
order(order,key) |
order the previous properties and identify element by key | true |
| filters | ||
filter(closure) |
A generic filter that takes a boolean-closure | false |
has(key,values..) |
filter elements that don’t have key/value property (values or’d) | false |
has(key,compare,values..) |
filter elements that don’t have compared key/value property (values or’d) | false |
hasNot(key,values..) |
filter elements that do have key/value property (values or’d) | false |
hasNot(key,compare,values..) |
filter elements that do have compared key/value property (values or’d) | false |
interval(key,value1,value2) |
filter elements that don’t have value in range | false |
dedup |
remove any duplicates in current traversal step | false |
back(step) |
go back to elements seen at previous step | true |
simplePath |
filter all elements reached by a cyclic, non-simple path | false |
| side-effects | ||
sideEffect(closure) |
mutate elements according to the provided closure | false |
as(name) |
name the previous step for future reference | false |
linkOut(label,step,key?) |
create outgoing edge to previous vertices with key? being a weight property |
true |
linkIn(label,step,key?) |
create incoming edge to previous vertices with key? being a weight property |
true |
keep |
remove all elements not at current step (of current type) | true[v]/false[e] |
drop |
remove all elements at current step (of current type) | true[v]/false[e] |
groupCount |
count the number of previously specified properties (a distribution) | true |
groupCount(closure,closure) |
process current elements with closure and incr count with closure | true |
script(filename,args..) |
compute the script file against all vertices in the graph | false |
When a computation requires the history of a traversal, combinatoric explosions can occur which are expensive in terms of both space (the size of the output) and time (computing the output). The following steps are steps that turn on path computations.
In short, be wary of long (or non-filtering) traversals that make use of path information as this can greatly hinder performance and lead to memory issues (even disk memory issues!).

Grant did an amazing job keeping the crowd up and dancing all night. He helped with music requests in the weeks leading up to the event as well. During the gala we needed to recognize some members on the microphone. Grant was very professional during the announcements and was an entertaining emcee. 43rd Productions was a great choice for our event.
-Mark F. (Gala)
43rd Productions was great to work with and is highly recommended! My event had multiple dates and times, which could have been hard to work around with a different company, but for each time I requested, 43rd Productions was on time and did all of the equipment set up and sound checks. It was great knowing that the business is run by ISU students who are supportive of other student organizations at Iowa State University.
-Szumei L. (Recruitment Event)
Grant was a great DJ for our fall philanthropy, Kappa Con Queso! He was very accommodating and made sure that people were up and dancing. The lights and sound was perfect for our house and event! Grant MADE Kappa Con Queso the fun environment and rememberable philanthropy that everyone looks forward to each year. Can't wait to use him again! Thanks Grant!!

“Does what goes on inside show on the outside? Someone has a great fire in his soul and nobody ever comes to warm themselves at it, and passers-by see nothing but a little smoke at the top of the chimney.” - Vincent Van Gogh
Example


Neptune's Data Model
Neptune is a sparse, distributed, persistent multidimensional sorted
map(from Bigtable's data model).
- Table: All datas are stored in logical data
storage called "Table". Table is identified by table name and a table
name must be unique in a neptune cluster.
- Column: A table has multiple columns. A columns has same
meaning RDBMS's column. Column must be defined when table is created or
can be added with "add column" instrunction.
- Row: A table consists of numerous rows.
- Row.Key: Each row has unique identifier,
"rowkey". Neptune automatically creates rowkey, while user
explicitly specifies row key column in a relational database. Data is
sorted by Row.Key. Row-Key is String type.
- Cell: Cell is a intersection of row and column. Cell can
have many key-value pairs(Cell.Key-Cell,Value).
- Cell.Key: Datas in a cell identified by Cell.Key and sored
by Cell.Key. Cell.Key is String type.
- Cell.Value: A Cell.Value has multiple versions and
sorted by timestamp in descending order. Each version stores byte

Version 1.3a
| AUTHOR | : | Hans-Gert Graebe |
| ADDRESS | : | Univ. Leipzig, Institut f. Informatik, D - 04109 Leipzig, Germany |
| URL | : | http://www.informatik.uni-leipzig.de/~graebe |
The GeoProver is a small package for mechanized (plane) geometry manipulations with non degeneracy tracing, available for different CAS platforms (Maple, MuPAD, Mathematica, and Reduce).
It provides the casual user with a couple of procedures that allow him/her to mechanize his/her own geometry proofs. Version 1.1 grew out from a course of lectures for students of computer science on this topic held by the author at the Univ. of Leipzig in fall 1996 and was updated after a similar lecture in spring 1998.
The (completely revised) version 1.2, finished in March 2002,
was set up as a generic software project to manage the code for
different platforms in a unified way. There is a close relationship
to the SymbolicData project (see
For examples we refer to the test file, but also to the SymbolicData GEO collection. It contains many (generic) proof schemes of geometry theorems, mainly from Chou's book. These proof schemes can be translated to the GeoProver syntax for different platforms with SymbolicData tools.
For version 1.3 the syntax definition (the GeoCode) was separated from the GeoProver implementation. The latter is an implementation of the GeoCode standard using the coordinate method.
Note that function names change with different versions of the GeoCode standard. GeoProver 1.3 implements the GeoCode standard 1.3.
Please send comments, bug reports, hints, wishes, criticisms etc. to the author.

"Men of Honor"
Carl Brashear (Cuba Gooding, Jr.) was born to a poor share cropping family in the Deep South. His daddy's admonishment of "don't end up like me" drives the ambitious lad to seek a life away from the farm and its toil. Carl becomes the first African-American to serve as a diver in the United States Navy, fighting racial prejudice, military bureaucracy and even crippling injury to fulfill his dream in "Men of Honor."
"Men of Honor" is, at its heart, a guy flick. The inspiring biography of Carl Brashear is made in the tradition of John Ford's 1957 movie "The Wings of Eagles" with John Wayne. Like "Wings of Eagles," "Men of Honor" is an old-fashioned yarn of one man overcoming every obstacle put before him, even devastating physical damage, to fulfill his life's goal. Where John Wayne's Frank "Spig" Weads must overcome paralysis and a failed marriage to become a key strategist of air power in the Pacific during WWII, Carl Brashear must face racial prejudice, narrow mindedness and physical trauma as his main obstacles.
Cuba Gooding Jr. does a fine job portraying the smart, though under educated, Carl. As a boy, he proves himself to be a first rate swimmer whose love of the water makes him an ideal candidate to be a Navy diver. But, in the 50's, a black man in the U.S. Navy had three career options - cook, officer's valet or, as his chief tells him, "get the #$%& out of the Navy." Carl defies the racial barriers of the time and challenges the whites-first policy of the military. His commander, Captain Pullman (Powers Boothe), sees past the color obstacle and recommends Carl for dive school. But, for each wall of prejudice Carl overcomes, he faces a bigger one.
Once ensconced in the school, Carl is forced to deal with Master Chief Billy Sunday (Robert DeNiro), the dive school master who holds a grudge against blacks. Sunday has the same roots as Carl - Billy, too, comes from a poor, southern farming family - but has a deep resentment of blacks stemming from his youth. For every obstacle Sunday and the school commander Mr. Pappy (Hal Holbrook) place before Carl, the young man hurdles past each, steadily earning the grudging respect of his chief. Eventually, the two men, Carl and Billy, develop a mutual bond and Master Chief Sunday pulls in markers from his comrades to help Carl achieve his goals - respected Navy diver and a Master Chief rating of his own.
This old-fashioned style story flows along in a typical manner for this kind of bio flick. We meet a young Carl on the family farm as he tries to help his father with the work. Dad is adamant that his kids go to school, not work in the fields. This father's desire for a better life for his son influences Carl, strongly, and inspires him to strive for what he wants out of life. As the adult Carl begins his naval career, as a cook, the old adage of success being 10% inspiration and 90% perspiration holds true for the man. Carl has to work twice as hard as his white peers and, despite his seventh grade education and with the help of an attractive librarian, Jo (Aunjanue Ellis), competes with them as an equal. It's not all beer and skittles for Carl as he must overcome the prejudice of the white military bureaucracy against a black man climbing the ladder of success. As one expects, since this is a true story, Carl graduates in the face of adversity.
The final leg of the story has Carl, now a respected diver, called upon to lend his underwater talents to find a nuclear device - a 50 megaton bomb - that was lost during a B-52 accident off of the coast of Spain. This part provides the most raw tension in the film as Carl is swept away by a Russian sub skulking in the area looking for the bomb. This action packed sequence brings up the bomb, but leads to an accident that costs Carl his leg. The end of the story shows Carl, now with the help of Billy Sunday, overcome his handicap and become the first amputee ever returned to full duty in the Navy. Carl keeps his coveted job as a senior diver and gets the Master Chief rating - the highest non-commissioned rating in the U.S. Navy.
While Gooding does a good job in portraying Carl Brashear, Robert DeNiro stands out as the gruff, tyrannical Master Chief Sunday. Giving a perf that is a departure from what he's done lately, DeNiro plays the son of a poor white sharecropping family who escaped that plight and found a home in the Navy.  Carl's determination, ability and dedication to the Navy slowly turn the chief and his attitude toward Brashear. The change is neither abrupt nor easy and DeNiro puts a convincing spin on his conversion.
The talented supporting cast is not given enough to do, for the most part. Hal Holbrook is wasted as the bigoted dive school commander who refuses to see Carl's inherent talent and ability. Powers Boothe and David Keith lend an enlightened quality to their respective roles as Carl's commanding officers at different periods in the story. They symbolize intelligent officers who see beyond the color barrier. Aunjanue Ellis, as Jo, puts a distinctive arc on her love interest role as she, first, helps Carl then, later falls in love and marries him. Michael Rapaport is a two-dimensional stick figure who is the only white guy who unconditionally accepts Carl into the fold. Charlize Theron is miscast as Sunday's young wife, though the actress makes the most of the small role.
Helmer George Tillman ("Soul Food") shows a deft hand in mustering the talents of his actors and his behind-the-camera crew. Cinematography by Anthony Richmond is straightforward and crisp. The underwater sequences have a murkiness that suits the deep-sea environment the divers work in, giving the film a you-are-there look. Production design, by Leslie Dilley, and costume design, by Salvador Perez, are first rate and capture the period feel with accuracy. In particular, the old-style dive gear used is convincing looking and rings true.
There is a high level of sentimentality throughout men of honor. Carl's daddy, as the young man boars the bus to join the Navy, gives him a handmade radio with the initials "ASNF" carved into the side. This image recurs throughout the film, a mystery until Chief Sunday, carves the true meaning beneath the initials - a son never forgets. Another bit, after Carl loses his leg, turns into a mini "Rocky III" as Chief Sunday drives the amputee to overcome his handicap. These sentimental interludes suit the flick, though, and blends with the rest of the inspirational story.
"Men of Honor" plays out the importance of honor and personal integrity without preaching. As such, the story is a solidly entertaining one that does not hammer the viewer with its message. It is an inspirational true story of a unique man that broke the Navy's color barrier for himself and those like him. Carl Brashear is a true hero and I'm glad his story is told. I give it a solid B.

Moss: A Measure of Software Similarity
What is Moss?
Moss is an automatic system for determining
the similarity of two C, C++, Java, or ML programs. To date, the main
application of Moss has been in detecting cheating in university programming
classes. Since its development two years ago, Moss has been very
effective in this role and is a significant improvement over other
cheating detection systems (at least, over those known to us).
An Internet Service (beta test)
Moss is now being provided as a free Internet service.
The service has been designed to be very easy to use. You
supply a list of files to compare and Moss does the rest.
The Moss server responds to a query with a list of pairs of programs
that have similar code. Moss also tells you which passages in the two
programs appear the same, making it easy to quickly compare the files
by hand. Finally, Moss can automatically eliminate matches to code
that one expects to be shared (e.g., libraries or instructor-supplied
code), thereby eliminating false positives that arise from legitimate
sharing of code.
Registering for Moss
Moss is being provided in the hope that it will benefit the
educational community; it is fast, easy to use, and free. Access to
Moss is currently restricted to instructors in programming courses.
To obtain a Moss account, send a request to<EMAIL_ADDRESS>Processing requests for accounts may take up to a day; once you have
an account queries are processed as soon as they are received.
How Does it Work?
Wouldn't you like to know! While there is a big difference between a
good cheating detection algorithm and a bad one, all such algorithms
can be fooled if one knows how they work. It's best if we don't say
too much about the ideas behind Moss. Suffice it to say that it is
more sophisticated than systems based on counting the frequency of
certain words in the program text (a widely used cheating-detection
heuristic); Moss actually examines program structure.


The uiScroll Adapter has some read-only properties which could be used to get knowledge of the uiScroll state. The first property is Adapter.isLoading. It is a boolean value indicating whether there are any pending load requests. So, datasource.adapter.isLoading = true means that the uiScroll is working right now and the viewport will be updated soon. 125ms delay was added to the Datasource.get implementation in this sample.
In these demos the Datasource is being instantiated via operator new. The main purpose is to protect Adapter methods/properties from too early calls. The augmentation of the Datasource object occurs during the uiScroll instantiating, so providing the object initializer into the *uiScroll directive (datasource: IDatasource = { get: ... }) may lead to problems. For example
Of course the problem could be avoided by writing something like datasource.adapter && datasource.adapter.isLoading, but instantiating the Datasource object via operator new solves the issue by immediately setting up the Adapter mock object on the Datasource's constructor. It defines the adapter property and null-returning stub methods on it. The uiScroll will override this adapter property after it is integrated to the App component.

ofxCvColorImage methods
clear()
void ofxCvColorImage::clear()
Clears the pixel data of the image. The image must be allocated again with a call to allocate() before it can be used.
contrastStretch()
void ofxCvColorImage::contrastStretch()
This increases the contrast of the image remapping the brightest points in the image to white and the darkest points in the image to black.
convertHsvToRgb()
void ofxCvColorImage::convertHsvToRgb()
Converts the image from values in the Hue Saturation and Value color space (sometimes called Hue Saturation Brightness) to values in the Red Green and Blue color space.
convertRgbToHsv()
void ofxCvColorImage::convertRgbToHsv()
Converts the image from values in the Red Green and Blue color space to values in the Hue Saturation and Value color space (sometimes called Hue Saturation Brightness)
convertToGrayscalePlanarImage(...)
void ofxCvColorImage::convertToGrayscalePlanarImage(ofxCvGrayscaleImage &grayImage, int whichPlane)
Copies the pixels of the ofxCvColorImage into an ofxCvGrayscale image. You can optionally specify whether you want to use the R G or B channel of the ofxCvColorImage to set the values of the ofxCvGrayscale.
convertToGrayscalePlanarImages(...)
void ofxCvColorImage::convertToGrayscalePlanarImages(ofxCvGrayscaleImage &red, ofxCvGrayscaleImage &green, ofxCvGrayscaleImage &blue)
Copies the different channels of the ofxCvColorImage into 3 different grayscale images using the R G and B channels of the ofxCvColorImage.
convertToRange(...)
void ofxCvColorImage::convertToRange(float min, float max)
Maps the pixels of an image to the min and max range passed in.
colors.setFromPixels(grabber.getPixelsRef());
first = colors; // will leave unaltered
second = colors; // change it
second.convertToRange(100, 140); // super low contrast
operator+=(...)
void ofxCvColorImage::operator+=(float value)
Adds the pixel data of the right hand side image from the current image:
first += second; // both are ofxCvFloatImage instances
operator-=(...)
void ofxCvColorImage::operator-=(float value)
Subtracts the pixel data of the right hand side image from the current image:
first -= second; // both are ofxCvFloatImage instances
operator=(...)
void ofxCvColorImage::operator=(unsigned char *_pixels)
Sets the ofxCvColorImage from the pixels pointer. Be sure that the pixels are the same size and dimensions as the ofxCvColorImage.
operator=(...)
void ofxCvColorImage::operator=(const ofxCvGrayscaleImage &mom)
Copies ofxCvGrayscaleImage to another ofxCvShortImage using the = symbol.
~~~~{.cpp} imageOne = imageTwo; // make sure that the dimensions and ROI match
operator=(...)
void ofxCvColorImage::operator=(const ofxCvColorImage &mom)
Copies the data from an ofxCvColorImage into the instance using the = symbol.
colorImage1 = colorImage2; // make sure that the dimensions and ROI match
operator=(...)
void ofxCvColorImage::operator=(const ofxCvFloatImage &mom)

ofxCvImage first;
first.allocate(640, 480);
ofxCvImage second;
second.allocate(320, 240);
second.scaleIntoMe(first); // first is now 320,240
set(...)
void ofxCvColorImage::set(float value)

set(...)
void ofxCvColorImage::set(int valueR, int valueG, int valueB)
Set all the pixels in the image to the float value passed in as a color using 0 to 255 scale for each channel. This is useful for blanking or filling an image quickly.
setFromGrayscalePlanarImages(...)
void ofxCvColorImage::setFromGrayscalePlanarImages(ofxCvGrayscaleImage &red, ofxCvGrayscaleImage &green, ofxCvGrayscaleImage &blue)
This method allows you use multiple ofxCvGrayscaleImage images to create a full color image. Each ofxCvGrayscaleImage represents the data of one channel, r, g, b.
setFromPixels(...)
void ofxCvColorImage::setFromPixels(const unsigned char *_pixels, int w, int h)
Set all the pixels in a ofxCvShortImage from a pointer to an array of unsigned char values, using the w and h parameters to determine the dimensions of the image.
setRoiFromPixels(...)
void ofxCvColorImage::setRoiFromPixels(const unsigned char *_pixels, int w, int h)
Set the Region Of Interest using a pointer to an unsigned char array and a w,h to define the area of the ROI

Is there a type class for a semiring with 0 ≠ 1
?
I tried [semiring α] [zero_ne_one_class α]
but then I ended up with two different definitions of one.
try to use old structure command and build a new class
the diamond death you just experienced
I tried
[semiring α] [zero_ne_one_class α]
but then I ended up with two different definitions of one.
Did you also end up with two different definitions of zero?
Yes.
Same question for ring
.
Would it have been better to define zero_ne_one_class
as
class zero_ne_one_class (α : Type*) [has_zero α] [has_one α] : Prop := (zero_ne_one : 0 ≠ 1)
Yes. There is not much I can do about it
Well, we can define our own has_zero_ne_one
, right?
In the way that Chris suggested
Sure. I would ask the reason for the use though, it seems not so useful
I'm doing univariate polys, and I'm trying to prove degree_of (X : uv_polynomial α) = 1
how is degree_of defined?
and X
after unfolding it looks like this sup ((single 1 1).support) id = 1
unfolding single makes it become this sup (ite (1 = 0) ∅ (singleton 1)) id = 1
is there decidable equality?
or are you classical
Yes.
there is decidable equality
I could probably get around it by proving alternative lemmas like degree_of_monomial
. Or just make 0 \ne 1
an argument to the theorem.
I used a typeclass nonzero_ring
in my metamath formalization of this one. Perhaps is_nonzero
can be a typeclass depending on ring
instead of has_zero
and has_one
?
nonzero semiring seems like a bad idea though, it's not nearly as nice as it sounds since it is not cancellative
Chris, from a mathematical point of view I am not so sure that people care too much about semirings. However I know lean is different. All I'm saying is that if it's easier to work with rings than semirings then from the point of view of mathematical applications you'll be losing essentially nothing.
I have the same problem with rings.
I used a typeclass
nonzero_ring
in my metamath formalization of this one. Perhapsis_nonzero
can be a typeclass depending onring
instead ofhas_zero
andhas_one
?
Do you mean extending ring
or with ring
as an argument?
nonzero_ring
would extends ring
, is_nonzero : Prop
would have [ring A]

Decentralized VPN
The Goal
Veles Core is an open-source software project that aims to help the people of Internet to retain their freedom of access to an information and to improve privacy of the communications over the Internet by building decentralzied service based on VPN and multi-hop technology.
Taking advantage of the recent developents in the blockchain technology, related consensus mechanisms and concepts we're able to solve several issues from which current open anoymisation services suffer, which they are either commercial or based solely on volunteer networks. Making it a great deal more difficult and expensive for a bad actors or oppresive governments to disrupt the service or to invade one's privacy.
It also shows us how quickly a network can grow and progress and how well are people able to cooperate if every resources and effort are awarded fairly. Anyone can participate in the network in several roles, from miners, masternode operators, or people getting paid for their unused traffic.
Blockchain and related technology has shown use quite effective solutions to fundamental problems of distributed systems, such as fault tolerance. We have further leveraged these ideas by implementing new innovative concepts that
We're also set on continuously back-porting latest improvements and updates from Bitcoin
and other related code-bases, so common issues get solved faster and more effectively. That's
why we can now offer Dash features such as masternodes or governance protocol alongside with
new Bitcoin features like SegWit or blockchain pruning.
In order to provide the best ecosystem for the decentralized dVPN and multi-hop services,
we have built custom blockchain and masternode network aimed at robustness, security
and reliability.
We have further leveraged this technology by implementing innovative concepts aimed
to tackle the issues that have emerged within the industry, such as several approaches against 51% attacks,
multiple independent PoW chains, instamine protection, adaptive block spacing, dynamic capped block rewards,
and many others.
We're set to be continuously back-porting latest improvements and updates from Bitcoin
and other related code-bases. That's why we can now offer Dash features such as masternodes
or governance protocol alongside with new Bitcoin features like SegWit or blockchain pruning.
Currently we are working on network improvements such as Proof-of-stake as an additional consensus
algorithm or the implementation of Deterministic Masternode System for the more reliable,
on-chain masternode synchronisation.

Because Veles cryptocurrency aka VLS as a store of value is an important part of the Veles Core ecosystem,
setting up VLS monetary policy had been very important area of focus in the early stage of the project,
until VCIP01 has been activated and later Maximum Supply has been also formally estabilished to 2.5m VLS.
Block rewards on Veles Network are dynamic, matching hashrate of the algo. Unlike in traditional PoW systems, on Veles Network is not possible to mine low-cost coins, and get full block reward when the hashrate would be low.
However, the dynamic block reward is limited by Maximum block reward,
to prevent unexpected inflation and not to exceed planned supply release, reached only with sufficient
hashrate. Minimum block would attract miners in case the hashrate of certain algo would get too low.
We have decided to use our concept non-linear, decreasing halving frewuency to prevent unneccessary long inflation period during the full PoW launch, but still keeping slow but steady release of VLS tokens for miners for over a century.
This creates supply curve and inflation rate more friendly to an investor, where
• over 50% of the max. supply will be in circulation within 2 years,
• over 70% of the max. supply within 5 years
• the rest will be released slowly in more than century time
