A famous gang of pirates, Sea Dogs, has come back to their hideout from one of their extravagant plunders. They want to split their treasure fairly amongst themselves, that is why You, their trusted financial advisor, devised a game to help them:

All of them take a sit at their round table, some of them with the golden coins they have just stolen. At each iteration of the game if one of them has equal or more than 2 coins, he is eligible to the splitting and he gives one coin to each pirate sitting next to him. If there are more candidates (pirates with equal or more than 2 coins) then You are the one that chooses which one of them will do the splitting in that iteration. The game ends when there are no more candidates eligible to do the splitting.

Pirates can call it a day, only when the game ends. Since they are beings with a finite amount of time at their disposal, they would prefer if the game that they are playing can end after finite iterations, and if so, they call it a good game. On the other hand, if no matter how You do the splitting, the game cannot end in finite iterations, they call it a bad game. Can You help them figure out before they start playing if the game will be good or bad?


You were dreaming that you are traveling to a planet named Planetforces on your personal spaceship. Unfortunately, its piloting system was corrupted and now you need to fix it in order to reach Planetforces.

Space can be represented as the $$$XY$$$ plane. You are starting at point $$$(0, 0)$$$, and Planetforces is located in point $$$(p_x, p_y)$$$.

The piloting system of your spaceship follows its list of orders which can be represented as a string $$$s$$$. The system reads $$$s$$$ from left to right. Suppose you are at point $$$(x, y)$$$ and current order is $$$s_i$$$:

- if $$$s_i = \text{U}$$$, you move to $$$(x, y + 1)$$$;
- if $$$s_i = \text{D}$$$, you move to $$$(x, y - 1)$$$;
- if $$$s_i = \text{R}$$$, you move to $$$(x + 1, y)$$$;
- if $$$s_i = \text{L}$$$, you move to $$$(x - 1, y)$$$.

Since string $$$s$$$ could be corrupted, there is a possibility that you won't reach Planetforces in the end. Fortunately, you can delete some orders from $$$s$$$ but you can't change their positions.

Can you delete several orders (possibly, zero) from $$$s$$$ in such a way, that you'll reach Planetforces after the system processes all orders?

Well, most operating systems do let you know when you've reached a critical low. However, it is up to the user to do the work of clearing out the space. I know that Windows will do what it can to assist, as does the latest Ubuntu (not sure about other Linux distros), but it can only do so much. I haven't played with anything beyond Tiger to any extent, so I don't know if those also do what they can to assist in freeing up space. Hoping to change that little problem soon, though...

Today is birthday of a Little Dasha — she is now 8 years old! On this occasion, each of her n friends and relatives gave her a ribbon with a greeting written on it, and, as it turned out, all the greetings are different. Dasha gathered all the ribbons and decided to throw away some of them in order to make the remaining set stylish. The birthday girl considers a set of ribbons stylish if no greeting written on some ribbon is a substring of another greeting written on some other ribbon. Let us recall that the substring of the string s is a continuous segment of s.

Help Dasha to keep as many ribbons as possible, so that she could brag about them to all of her friends. Dasha cannot rotate or flip ribbons, that is, each greeting can be read in a single way given in the input.


A boy Bob likes to draw. Not long ago he bought a rectangular graph (checked) sheet with n rows and m columns. Bob shaded some of the squares on the sheet. Having seen his masterpiece, he decided to share it with his elder brother, who lives in Flatland. Now Bob has to send his picture by post, but because of the world economic crisis and high oil prices, he wants to send his creation, but to spend as little money as possible. For each sent square of paper (no matter whether it is shaded or not) Bob has to pay 3.14 burles. Please, help Bob cut out of his masterpiece a rectangle of the minimum cost, that will contain all the shaded squares. The rectangle's sides should be parallel to the sheet's sides.


I am not a Microsoft SQL expert, but I need to solve this trouble.
I must configure a MS SQL access as read only user.
I understood that I must set "db_datareader* permission for this new read only user (guide: https://www.itsupportguides.com/knowledge-base/server-side-tips/sql-management-studio-how-to-create-read-only-users/)
After that I would limit read only user database view.
I would that this limited user can only see specific tables inside specific database (databases).
Is it possible?
How can I do it?

As the name of the task implies, you are asked to do some work with segments and trees.

Recall that a tree is a connected undirected graph such that there is exactly one simple path between every pair of its vertices.

You are given $$$n$$$ segments $$$[l_1, r_1], [l_2, r_2], \dots, [l_n, r_n]$$$, $$$l_i < r_i$$$ for every $$$i$$$. It is guaranteed that all segments' endpoints are integers, and all endpoints are unique — there is no pair of segments such that they start in the same point, end in the same point or one starts in the same point the other one ends.

Let's generate a graph with $$$n$$$ vertices from these segments. Vertices $$$v$$$ and $$$u$$$ are connected by an edge if and only if segments $$$[l_v, r_v]$$$ and $$$[l_u, r_u]$$$ intersect and neither of it lies fully inside the other one.

For example, pairs $$$([1, 3], [2, 4])$$$ and $$$([5, 10], [3, 7])$$$ will induce the edges but pairs $$$([1, 2], [3, 4])$$$ and $$$([5, 7], [3, 10])$$$ will not.

Determine if the resulting graph is a tree or not.


Thank you to everybody who came to my birthday dinner! It ended up being at Picco, because Addis Red Sea couldn’t seat us, but we had amazingly yummy pizza, and followed it with sundaes. And yes, everybody sang to me. :-)
One black jacket was left behind, which I believe probably belongs to motive_nuance or queenofhalves. Let me know whose it is and I’ll make arrangements to get it back to you.
And now, it’s time for me to collapse. Happily, though.

The game of Berland poker is played as follows. There are $$$n+1$$$ people: $$$n$$$ players, numbered from $$$1$$$ to $$$n$$$, and the dealer. The dealer has a deck which contains cards of four different suits (the number of cards of each suit is not necessarily the same); the number of cards in the deck is divisible by $$$n$$$. The dealer gives all cards to the players, so that every player receives the same number of cards, and the whole deck is used.

After the cards are dealt, every player chooses one of four suits (independently) and discards all cards from their hand which do not belong to their chosen suit. The winner of the game is the player with the maximum number of cards left in their hand. The number of points the winner receives is $$$x - y$$$, where $$$x$$$ is the number of cards in the winner's hand, and $$$y$$$ is the maximum number of cards among all other players; everyone else receives $$$0$$$ points. Note that it means that if there are multiple players with the maximum number of cards, everyone receives $$$0$$$ points.

Since every player wants to maximize their odds to win, they will choose a suit with the maximum number of cards in their hand.

Monocarp is the dealer. He has already given some cards to the players; the $$$i$$$-th player received $$$a_{i,j}$$$ cards of suit $$$j$$$. Note that the number of cards in players' hands don't have to be the same at this moment. Monocarp has $$$b_1, b_2, b_3, b_4$$$ cards of suit $$$1, 2, 3, 4$$$ respectively left in his deck. He has to give them to the players so that, after all cards are dealt, every player has the same number of cards.

For each player, calculate the maximum number of points they can receive among all ways to deal the remaining cards according to the rules of the game.


You got a job as a marketer in a pet shop, and your current task is to boost sales of cat food. One of the strategies is to sell cans of food in packs with discounts.

Suppose you decided to sell packs with $$$a$$$ cans in a pack with a discount and some customer wants to buy $$$x$$$ cans of cat food. Then he follows a greedy strategy:

- he buys $$$\left\lfloor \frac{x}{a} \right\rfloor$$$ packs with a discount;
- then he wants to buy the remaining $$$(x \bmod a)$$$ cans one by one.

$$$\left\lfloor \frac{x}{a} \right\rfloor$$$ is $$$x$$$ divided by $$$a$$$ rounded down, $$$x \bmod a$$$ is the remainer of $$$x$$$ divided by $$$a$$$.

But customers are greedy in general, so if the customer wants to buy $$$(x \bmod a)$$$ cans one by one and it happens that $$$(x \bmod a) \ge \frac{a}{2}$$$ he decides to buy the whole pack of $$$a$$$ cans (instead of buying $$$(x \bmod a)$$$ cans). It makes you, as a marketer, happy since the customer bought more than he wanted initially.

You know that each of the customers that come to your shop can buy any number of cans from $$$l$$$ to $$$r$$$ inclusive. Can you choose such size of pack $$$a$$$ that each customer buys more cans than they wanted initially?

My good friend Jenn Sodini returns for a fun foray into the cultural milieu of our exponentially chaotic and weird age.
Jenn is the founder and creator of Evolve and Ascend. The Author of Everyday Amenti, the host of Radio Amenti (podcast), a public speaker, creator of the Amenti Oracle deck and much more. She is a life long student of the occult, plant medicines, and esoteric wisdom. Jenn is on a true spiritual path, which sets her apart from many who claim to walk the path but end up falling into the "new age woo" traps of spiritual bypassing, gaslighting, spiritual materialism etc... She carries her light while realizing the dark and integrating the shadow to let her truth, wisdom and compassion shine in the healthiest, most grounded, and holistic way possible.
We have a really fun chat about culture, media,and the overall tech/online environment, the conspiracy and conspirituality landscape, beliefs, performative slacktivism, social media and its influencers, memes, viral videos, pop culture, magick, the occult, cringe inducing celebrity culture, the freedom and sanity of going for long bike rides and much more. Again, one of my favorite conversations with one of my favorite people.

Mike is the president of country What-The-Fatherland. There are n bears living in this country besides Mike. All of them are standing in a line and they are numbered from 1 to n from left to right. i-th bear is exactly ai feet high.

A group of bears is a non-empty contiguous segment of the line. The size of a group is the number of bears in that group. The strength of a group is the minimum height of the bear in that group.

Mike is a curious to know for each x such that 1 ≤ x ≤ n the maximum strength among all groups of size x.


Author note: I think some of you might remember the problem "Two Melodies" from Eductational Codeforces Round 22. Now it's time to make it a bit more difficult!

Alice is a composer, and recently she had recorded two tracks that became very popular. Now she has got a lot of fans who are waiting for new tracks.

This time Alice wants to form four melodies for her tracks.

Alice has a sheet with n notes written on it. She wants to take four such non-empty non-intersecting subsequences that all of them form a melody and sum of their lengths is maximal.

Subsequence is a sequence that can be derived from another sequence by deleting some elements without changing the order of the remaining elements.

Subsequence forms a melody when each two adjacent notes either differ by 1 or are congruent modulo 7.

You should write a program which will calculate maximum sum of lengths of such four non-empty non-intersecting subsequences that all of them form a melody.

Petya and Vasya arranged a game. The game runs by the following rules. Players have a directed graph consisting of n vertices and m edges. One of the vertices contains a chip. Initially the chip is located at vertex s. Players take turns moving the chip along some edge of the graph. Petya goes first. Player who can't move the chip loses. If the game lasts for 106 turns the draw is announced.

Vasya was performing big laboratory work in "Spelling and parts of speech" at night before the game, so he fell asleep at the very beginning of the game. Petya decided to take the advantage of this situation and make both Petya's and Vasya's moves.

Your task is to help Petya find out if he can win the game or at least draw a tie.


The position of the leftmost maximum on the segment $$$[l; r]$$$ of array $$$x = [x_1, x_2, \ldots, x_n]$$$ is the smallest integer $$$i$$$ such that $$$l \le i \le r$$$ and $$$x_i = \max(x_l, x_{l+1}, \ldots, x_r)$$$.

You are given an array $$$a = [a_1, a_2, \ldots, a_n]$$$ of length $$$n$$$. Find the number of integer arrays $$$b = [b_1, b_2, \ldots, b_n]$$$ of length $$$n$$$ that satisfy the following conditions:

- $$$1 \le b_i \le m$$$ for all $$$1 \le i \le n$$$;
- for all pairs of integers $$$1 \le l \le r \le n$$$, the position of the leftmost maximum on the segment $$$[l; r]$$$ of the array $$$b$$$ is equal to the position of the leftmost maximum on the segment $$$[l; r]$$$ of the array $$$a$$$.

Since the answer might be very large, print its remainder modulo $$$10^9+7$$$.


You are given an array of integers $$$a_1, a_2, \ldots, a_n$$$. Calculate the number of subarrays of this array $$$1 \leq l \leq r \leq n$$$, such that:

- The array $$$b = [a_l, a_{l+1}, \ldots, a_r]$$$ occurs in the array $$$a$$$ as a subsequence exactly once. In other words, there is exactly one way to select a set of indices $$$1 \leq i_1 < i_2 < \ldots < i_{r - l + 1} \leq n$$$, such that $$$b_j = a_{i_j}$$$ for all $$$1 \leq j \leq r - l + 1$$$.

In the evening Polycarp decided to analyze his today's travel expenses on public transport.

The bus system in the capital of Berland is arranged in such a way that each bus runs along the route between two stops. Each bus has no intermediate stops. So each of the buses continuously runs along the route from one stop to the other and back. There is at most one bus running between a pair of stops.

Polycarp made n trips on buses. About each trip the stop where he started the trip and the the stop where he finished are known. The trips follow in the chronological order in Polycarp's notes.

It is known that one trip on any bus costs a burles. In case when passenger makes a transshipment the cost of trip decreases to b burles (b < a). A passenger makes a transshipment if the stop on which he boards the bus coincides with the stop where he left the previous bus. Obviously, the first trip can not be made with transshipment.

For example, if Polycarp made three consecutive trips: "BerBank" $$\rightarrow$$ "University", "University" $$\rightarrow$$ "BerMall", "University" $$\rightarrow$$ "BerBank", then he payed a + b + a = 2a + b burles. From the BerBank he arrived to the University, where he made transshipment to the other bus and departed to the BerMall. Then he walked to the University and returned to the BerBank by bus.

Also Polycarp can buy no more than k travel cards. Each travel card costs f burles. The travel card for a single bus route makes free of charge any trip by this route (in both directions). Once purchased, a travel card can be used any number of times in any direction.

What is the smallest amount of money Polycarp could have spent today if he can buy no more than k travel cards?


The number of consumers making purchases online continues to increase. This year, American online retail sales are projected to reach $224.2 billion. It is the new wave of commerce and, depending on the industry, ecommerce represents either an opportunity for big profit or a death knell for the brick-and-mortar business. The landscape is changing, and businesses must adapt to survive.
Marketing is the way companies interact with consumers to create relationships that are beneficial to both parties. Businesses use marketing to identify their audience before advertising to them. Today, this is most visible through social media interactions and contests.

Intellisense is great, but it is no substitute for reading documentation. I’m always upset when I hear developers say that their primary source of learning is looking at what intellisense offers them.
There are a few methods which can be considered part of LINQ, which aren’t extension methods. This means that unless you actually type out Enumerable, you will never see then in intellisense. The nature of extensions methods means that you won’t ever type out enumerable, so these methods are less discoverable than others.
System.Linq.Enumerable is where the library implementation of LINQ to objects lives. Empty, Range and Repeat methods are hand tools.
Empty is useful for those cases when you don’t want a null object, but instantiating an Enumerable is wasteful. For example, creating a new empty List of string to pass to a linq expression when some other data source may return null or empty. I’m thinking of combining linq expressions here. The anti-wasteful programmer might say “well, just use a new empty string array”. And that programmer would be right. This would use less memory than a new List. But the really nice part about Empty is that its underlying implementation is just a generic singleton based on type. That means instead of 1000 or 100,000 “new string” in your code, eating up a tiny bit of ram (ok, its pretty small here, I know, but doesn’t every little bit help?) you have only one empty string array that all cases can share.
Range should be familiar to anyone coming from python. It just returns an enumerable range of numbers from start to end. IMO it isn’t as nice as pythons, but I can always write my own. Still not clear? Here is how you would write a summary from one to one hundred million of n-1 + 1/i.
var x = Enumerable.Range(1, 100000000).Aggregate(0f, (a, b) => (float)(a + 1 / (float)b));
Finally, Repeat is similar to range, it just gives an enumerator which yields the same object/value repeatedly.
Example of using repeat to make 5 hello worlds:
var fiveWorlds = Enumerable.Repeat(“Hello World”, 5);
Console.WriteLine(fiveWorlds.Aggregate((a,b)=>a + “\n” +b ));

Simon has a prime number x and an array of non-negative integers a1, a2, ..., an.

Simon loves fractions very much. Today he wrote out number $$\frac{1}{x^{a_1}} + \frac{1}{x^{a_2}} + \ldots + \frac{1}{x^{a_n}}$$ on a piece of paper. After Simon led all fractions to a common denominator and summed them up, he got a fraction: $$\text{S}$$, where number t equals xa1 + a2 + ... + an. Now Simon wants to reduce the resulting fraction.

Help him, find the greatest common divisor of numbers s and t. As GCD can be rather large, print it as a remainder after dividing it by number 1000000007 (109 + 7).


Hi, I’ve bought a dedicated wildcard SSL certificate from the CF control panel. I’m trying to install it on IIS 6.1.
I’ve tried a myriad of different things, converting formats with OpenSSL and I can’t get it to recognise it as a valid certificate.
To import a certificate, it needs to be .pfx
To complete a CSR request, the file provided needs to be .cer
CF doesn’t provide files, just the raw keys to make the certificates. I’ve followed their guide for IIS but it just takes me to Digicert’s website where the advice is not tailored to CF’s format.
CF offers to generate a CSR and just give you the cert key and the private key but then you have to convert that to RSA private key and then bundle both of those into a pfx or cer file? And what of the CA key?
You can provide your own CSR but that only gets me as far as needing to complete the CSR myself in IIS.
Can anyone help with a few simple steps to get it into IIS?
Any advice appreciated!


How to Test a Breakout Board for Your Raspberry Pi
To test your homemade breakout board for the Raspberry Pi, you need a multimeter, a device for measuring current, voltage, and resistance. You can obtain a cheap one from a thrift shop for less than $10.
First, select resistance or continuity on the switch on the front of the meter and make sure that there are no shorts between adjacent wires in the ribbon cable. You will know it is a short when the continuity indicator bleeps or the resistance measurement shows zero or a very low ohm reading (less than 10 ohms).
Next, plug the cable into your Raspberry Pi with the ribbon running away from the board and the polarizing bump pointing into the board. Do not power up your Raspberry Pi yet.
Check that you have continuity between the five ground connections. Now power up your Pi and set your meter to measure voltage. Put the black or negative meter wire on a ground connector and the red or positive meter wire on a 5V block. You should see close to 5V.
Next measure the voltage between the ground and the two 3V3 connections in turn. Again, you should see a value very close to 3V3. If these checks fail, shut down the Raspberry Pi disconnect the cable and check all your wiring.

CLIENT: Community Workshop, Seattle CATEGORY: Sustainability Toolkit, Education TOOLS USED: Adobe Illustrator, MS Word
Connect the Green Dots is a sustainability toolkit for home life and community. This toolkit was developed for local community workshops, in the Seattle area, as a resource for individuals and organizations to provide an easy to understand roadmap for making more sustainable choices in their daily lives and how to influence their community. The goal of the toolkit is to get people thinking about their role in making more sustainable choices based on each of the four system conditions. The toolkit was presented in a video format. Each system condition was presented with examples, and participants actively participated in discussions creating an open dialog and idea generating workshop.
This toolkit was designed using The Natural Step Framework (TNS) guidelines. It is a science based framework consisting of four system conditions.
- Eliminate our contribution to the progressive buildup of substances extracted from the Earth’s crust (for example, heavy metals and fossil fuels)
- Eliminate our contribution to the progressive buildup of chemicals and compounds produced by society (for example, dioxins, PCBs, and DDT).
- Eliminate our contribution to the progressive physical degradation and destruction of nature and natural processes (for example, over harvesting forests and paving over critical wildlife habitat).
- Eliminate our contribution to conditions that undermine peoples’ capacity to meet their basic human needs (for example, unsafe working conditions, not enough pay to live on, a lack of safe affordable housing, and access to healthy food and safe water).


We are a group of computational, systems, and evolutionary biologists broadly interested in molecular evolution, population genetics, and the dynamics and evolution of gene regulatory networks. Our approach is both theoretical and experimental and we try to tackle the big questions in these fields by building on the latest advances in computer science and systems biology.

Is there a way to use filtering (searching) in CGridView for a model attribute which is not a DB column?
I have a User model which has a role attached to it (using Yii RBAC). In the manage users page I use CGridView to display all users and I also display each user’s role. I want to be able to search also by role but I don’t want to use a model relation between User and AuthItem because I would like to keep my RBAC code independent of the actual RBAC implementation that I use. I may switch to CPhpAuthManager or another (LDAP for example) at a later stage. I would like to stick to CAuthManager API for accessing and managing RBAC specific functions.
So is there a way to make CGridView search/filter a model attribute which is not DB-backed, i.e. continue to use the CActiveDataProvider for the normal model attributes and different provider (that is using CAuthManager for reading the roles) for the role field?
I can’t see any way that you would be able to sort or filter in CGridView using a non db attribute - the filtering/sorting is done using SQL generated from the model, so will only work on values that can be used in the SQL.
Depending on how you’re creating your CActiveDataProvider for use with the grid view, then you could perhaps do getData() on it, to retrieve the data, then manually sort it before passing it to the grid view, but obviously any such sorting and filtering would then only be applied to the current grid page.
well, I think it’s not impossible. but before that, how are you populating users’ roles in gridView now? you set their roles in their session or what?
and another question could be how many roles a user can have?
assuming each user has one role (just for simplicity, main idea would be the same) if I had this problem, I would use CArrayDataProvider instead of CActiveDataProvider. this way we can simply load our data from DB using Active Record and user Model, then we can filter it using whatever function we want, and finally, we can populate our ArrayDataProvider and pass it to view.
so our search function would be something like this: (pseudo code, of course)
$criteria = new CDbCriteria;
$criteria->condition = filtering normal db parameters
$rawResults = self::model()->findAll($criteria);
$usefulRawResults = self::attachRoles($rawResults); // you probably will attach each users role to its AR object so we can refer later, lets say using this function
$finalResults = self::filterByRole($specificRole, $usefulRawResults); // this function can simply loop users and check if one has this role or not, returning the ones pass the if
$arrayDataProvider = new CArrayDataProvider;
$arrayDataProvider <= we should make $finalResults ready and pass it to arrayDataProvider, documentations will help a lot
I think that’s the whole Idea, see if it works, and if there were any problems, let me know


Firecrackers scare Nian the monster, but they're wayyyyy too noisy! Maybe fireworks make a nice complement.

Little Tommy is watching a firework show. As circular shapes spread across the sky, a splendid view unfolds on the night of Lunar New Year's eve.

A wonder strikes Tommy. How many regions are formed by the circles on the sky? We consider the sky as a flat plane. A region is a connected part of the plane with positive area, whose bound consists of parts of bounds of the circles and is a curve or several curves without self-intersections, and that does not contain any curve other than its boundaries. Note that exactly one of the regions extends infinitely.


You are given an array of $$$N$$$ integers: $$$[A_1, A_2, \dots, A_N]$$$.

A subsequence can be derived from an array by removing zero or more elements without changing the order of the remaining elements. For example, $$$[2, 1, 2]$$$, $$$[3, 3]$$$, $$$[1]$$$, and $$$[3, 2, 1, 3, 2]$$$ are subsequences of array $$$[3, 2, 1, 3, 2]$$$, while $$$[1, 2, 3]$$$ is not a subsequence of array $$$[3, 2, 1, 3, 2]$$$.

A subsequence is microwavable if the subsequence consists of at most two distinct values and each element differs from its adjacent elements. For example, $$$[2, 1, 2]$$$, $$$[3, 2, 3, 2]$$$, and $$$[1]$$$ are microwavable, while $$$[3, 3]$$$ and $$$[3, 2, 1, 3, 2]$$$ are not microwavable.

Denote a function $$$f(x, y)$$$ as the length of the longest microwavable subsequence of array $$$A$$$ such that each element within the subsequence is either $$$x$$$ or $$$y$$$. Find the sum of $$$f(x, y)$$$ for all $$$1 \leq x < y \leq M$$$.

APPEAL TO ALL DEVELOPERS AND MEMBERS OF THE INTERNATIONAL LAW COMMUNITY
Anybody is welcome to commit to this Github repository if they have a smart contract idea that helps us build the Operating System for Ethscape's decentralised polity.
However, only if we go beyond the creation of an open-source code repository of smart contracts, meritorious as this may be, and achieve sovereign status will Ethscape prove its value in the real world. Our ultimate product therefore has to be a country, in the tradition of other nation building projects but without the fatal flaw of terrestrial territory.
That is why we work on Ethereum as the only “sovereign-grade”, censorship-resistant public chain fit for our purpose.
This is also why we hope we can appeal to all members of the Ethereum developer community who are looking for more political fulfilment in their development work, as well as members of the international law community who are challenged by the idea of a first-of-its-kind sovereign polity on blockchain without territory, tax or fiat money.

Vitalik the philatelist has a birthday today!

As he is a regular customer in a stamp store called 'Robin Bobin', the store management decided to make him a gift.

Vitalik wants to buy one stamp and the store will give him a non-empty set of the remaining stamps, such that the greatest common divisor (GCD) of the price of the stamps they give to him is more than one. If the GCD of prices of the purchased stamp and prices of present stamps set will be equal to 1, then Vitalik will leave the store completely happy.

The store management asks you to count the number of different situations in which Vitalik will leave the store completely happy. Since the required number of situations can be very large, you need to find the remainder of this number modulo 109 + 7. The situations are different if the stamps purchased by Vitalik are different, or if one of the present sets contains a stamp that the other present does not contain.


Leafy sea dragon
At first glance it’s hard to imagine that this is not a plant, but a real fish. An amazing feature of this animal is almost transparent tentacles, which are very similar to algae. However, they do not help in movement, but serve only to cover up.
This fish (Halieutichthys intermedius) is very similar to deep fried pancake with huge bulging eyes.
This copy was found quite recently – in 2005. Known about him only that they live at a depth of at least 2000 meters.
About this turtle have notes even in Chinese mythology. According to the legend, the man, who had many sins, had turned to this white turtle.
Guinea the Blowfish
This fish dwells in the Pacific ocean. The main feature, as You’ve probably noticed, is that it is able to inflate like a balloon.
Head Of The Gorgon
But this monster lives in the White sea. From the outside it seems as if it is a plant rooted in the bottom surface, however, in fact these tentacles are extremely agile, which allows the animal to move veryquickly in all directions. When the animal begins to move, it resembles a snake crawling on the head of the Gorgon Medusa.
Japanese magnetography dog
Despite its appearance, the fish is absolutely harmless to humans and eats only animals, Stripping them from the surface of the stones. Divers tell that this fish gives even pet and feed themselves with their hands.
The main feature of this fish is that it has very sharp thorns that are on both ends of the fin. Razor-sharp spikes used for self-defense, of course.
Although it is not a fish, but an instance is also quite interesting. This creates an unusual little coral colony on the bottom surface and the polyps form a round, translucent clusters, which are very similar to little balls.

Tsondu and Tenzing are playing a card game. Tsondu has $$$n$$$ monsters with ability values $$$a_1, a_2, \ldots, a_n$$$ while Tenzing has $$$m$$$ monsters with ability values $$$b_1, b_2, \ldots, b_m$$$.

Tsondu and Tenzing take turns making moves, with Tsondu going first. In each move, the current player chooses two monsters: one on their side and one on the other side. Then, these monsters will fight each other. Suppose the ability values for the chosen monsters are $$$x$$$ and $$$y$$$ respectively, then the ability values of the monsters will become $$$x-y$$$ and $$$y-x$$$ respectively. If the ability value of any monster is smaller than or equal to $$$0$$$, the monster dies.

The game ends when at least one player has no monsters left alive. The winner is the player with at least one monster left alive. If both players have no monsters left alive, the game ends in a draw.

Find the result of the game when both players play optimally.


Vasya likes everything infinite. Now he is studying the properties of a sequence s, such that its first element is equal to a (s1 = a), and the difference between any two neighbouring elements is equal to c (si - si - 1 = c). In particular, Vasya wonders if his favourite integer b appears in this sequence, that is, there exists a positive integer i, such that si = b. Of course, you are the person he asks for a help.

I’m trying to setup an alpine sshd container (on AWS Fargate) that runs only if needed that allows users to connect to other resources (in my case to have maintenance on an aws rds which is not publicly accessible).
As now I have setup everything and it is working fine, but I need help on some enhancements I’d like to apply
1) is it possible to have the tunnels automatically created by the server after the user connects ? I did found nothing about that, only client side configurations. The reason is that I want to remove the configuration from the user as much as possible
2) is there a way to create a DNS alias so I can set something like “permitopen=rds:3306” and the user then uses “-L 3307:rds:3306” ? Reason: I can simply restart the container to update the rds alias with a value from environmental variables/terraform/whatever. This makes switching rds very easy. I don’t like the idea of users having to use aws dns names (they are to loooong and possibly very similar to other RDS in same organization).Also maintaining ssh_config files on users side is not optimal… In addition those aliases will be used only by the container, so no route53 hosted zones, if possible
Thanks in advance !

- The Discontinuous Galerkin Method for Realistic Earthquake Modeling on HPC Infrastructure
We will present the arbitrary high-order derivative discontinuous Galerkin (ADER-DG) method on three-dimensional unstructured tetrahedral meshes for realistic earthquake modeling. The support of unstructured tetrahedral meshes highly expedites the model building process and allows for complex topography and complicated geological subsurface structures. Typical problem sizes require a good performance on parallel machines in order to simulate desired high frequencies that is given for ADER-DG. A special focus will lie on the implementation on dynamic rupture sources where the fault slip is a spontaneous consequence of the state of the fault. The code has been benchmarked by comparing results of the SCEC test case with other established numerical methods such as Finite Difference and Spectral Boundary Integral. An important result is that the ADER-DG method avoids spurious high-frequency contributions in the slip rate spectra, usually present in other dynamic rupture solvers, and therefore does not require artificial Kelvin-Voigt damping. To demonstrate the capabilities of the high-order accurate ADER-DG scheme we use the 1992 Landers earthquake as an example. It represents a complex fault system including branching and six curved fault segments. Furthermore, topography is respected in the discretized model to capture the surface waves correctly. Strong mesh coarsening or refinement at areas of interest is applied to keep the computational costs feasible. Finally current problems and further developments will be discussed.


It is a simplified version of problem F2. The difference between them is the constraints (F1: $$$k \le 2$$$, F2: $$$k \le 10$$$).

You are given an integer $$$n$$$. Find the minimum integer $$$x$$$ such that $$$x \ge n$$$ and the number $$$x$$$ is $$$k$$$-beautiful.

A number is called $$$k$$$-beautiful if its decimal representation having no leading zeroes contains no more than $$$k$$$ different digits. E.g. if $$$k = 2$$$, the numbers $$$3434443$$$, $$$55550$$$, $$$777$$$ and $$$21$$$ are $$$k$$$-beautiful whereas the numbers $$$120$$$, $$$445435$$$ and $$$998244353$$$ are not.

Answers to frequently asked
Details Ive omitted: Although this post has described the main ideas behind Bitcoin, there are many details I havent mentioned. In the early days of Bitcoin transaction fees were mostly set to zero, but as Bitcoin has gained in popularity, transaction fees have gradually bitcoin transaction fee so high risen, and are now a substantial additional incentive on top of the 25 bitcoin reward for mining a block. 175 176 State and provincial securities regulators, coordinated through the North American Securities Administrators Association, are investigating "bitcoin scams" and ICOs in 40 jurisdictions. "Users Bitcoins Seized by DEA". 78 About 20 of all bitcoins are believed to be lost. Encyclopedia of Physical Bitcoins and Crypto-Currencies. Is the Bitcoin address.
The obvious thing to do is for the payer to sign the whole transaction (apart from the transaction hash, which, of course, must be generated later). Line 6 tells us the size (in bytes) of the transaction. A more serious problem occurs if she broadcasts two separate transactions in which she spends the same infocoin with Bob and Charlie, respectively. Andresen later became lead developer at the Bitcoin Foundation. 34 Many altcoins have been created since then. 33 By 9 January the price had risen.38, but then crashed by 49.80 over the next 16 days. This is how Bitcoin works for most users. The second output bitcoin transaction fee so high is defined lines 23 and 24, with a similar format to the first output. Lets suppose that the miners working on fork B are the next to successfully mine a block: After they receive news that this has happened, the miners working on fork A will notice that fork B is now.

This will be enough to solve a simple proof-of-work puzzle, but not enough to solve a more difficult proof-of-work puzzle. Archived from the original on Retrieved Berson, Susan. What are the advantages of Bitcoin? This is used as an identifier for the transaction. The solution, of course, is to have a mechanism for providing change. "Bitcoin worth almost as much as gold". The n0 tells us its to be the first output from that transaction; well see soon how multiple outputs (and inputs) from a transaction work, so dont worry too much about this for now. "Chinese bitcoin miners eye sites in energy-rich Canada". The solution is to send you.15 bitcoins, and to send.05 bitcoins to a Bitcoin address which I own. For bitcoin's price to stabilize, a large scale economy needs to develop with more businesses and users. 107 Bitcoin Cash has a larger block size limit and had an identical blockchain at the time of fork. Originally, these tokens were struck in brass, but later used precious metals as bitcoin prices increased. 147 The exact number of bitcoin millionaires is uncertain as a single person can have more than one bitcoin wallet.
The Computationally-Difficult Problem Bitcoin mining a block is difficult because the SHA-256 hash of a block's header must be lower than or equal to the target in order for the block to be accepted by the network. No-one else could have created that bit string, and so Alice cant turn around and say No, I didnt mean to give Bob an infocoin. Its straightforward to modify the Bitcoin protocol so that the time to validation is much more sharply peaked around ten minutes. In general, gambling with Bitcoin is legal although this usually depends on the user's country or state of residence. Well call this ledger the block chain, since thats what the complete record will be called in Bitcoin, once we get. Archived from the original (PDF) on 28 December 2013. This allows the core of Bitcoin to be trusted for being completely neutral, transparent and predictable. Griffin and Amin Shams in 2018 suggests that trading associated with increases in the amount of the Tether cryptocurrency and associated trading at the Bitfinex exchange account for about half of the price increase in bitcoin in late 2017.

Additionally, merchant processors exist to assist merchants in processing transactions, converting bitcoins to fiat currency and depositing funds directly into merchants' bank accounts daily. "Bitcoin value gyrates amid report of Department of Justice manipulation investigation". Ill analyse double spending shortly. Individual mining rigs often have to wait for long periods to confirm a block of transactions and receive payment.
How the Bitcoin protocol actually works
This requires miners to perform these calculations before their blocks are accepted by the network and before they are rewarded. The blocksize limit is what ensures everyone can participate in the Bitcoin network, and it ensures everyone can participate anonymously should they choose too. Every 2,016 blocks (approximately 14 days at roughly 10 min per block the difficulty target is adjusted based on the network's recent performance, with the aim of keeping the average time between new blocks at ten minutes. Much of the trust in Bitcoin comes from the fact that it requires no trust at all. Archived from the original on 19 December 2013. The inputs in every transaction can be tracked in the blockchain to every previous transaction's outputs. Attempting to assign special rights to a local authority in the rules of the global Bitcoin network is not a practical possibility. Volatility is calculated on a yearly basis. Archived (PDF) from the original on Retrieved Put in the simplest terms, the quest for decentralised trust has quickly become an environmental disaster. Bitcoin nodes use the block chain to distinguish legitimate Bitcoin transactions from attempts to re-spend coins that have already been spent elsewhere. 36 On 5 December 2013, the People's Bank of China prohibited Chinese financial institutions from using bitcoins.

Server Clash: DELL's Quad Opteron DELL R815 vs HP's DL380 G7 and SGI's Altix UV10by Johan De Gelas on September 9, 2010 7:30 AM EST
The Quad Opteron Alternative
Servers with the newest Intel six-core Xeon hit the market in April. The fastest six-cores Xeons were able to offer up to twice the performance of six-core Opteron “Istanbul”. The reason for this was that the age of the integer core in AMD's Opteron was starting to show. While the floating point part got a significant overhaul in 2007 with the AMD "Barcelona" quad-core chip, the integer part was a tuned version of the K8, launched back in 2003. This was partly compensated by large improvements in the multi-core performance scaling departement: HT-assist, faster CPU interconnects, larger L3 caches, and so on.
To counter this lower per-core performance, AMD's efforts focused on the "Magny-Cours" MCMs that scaled even better thanks to HT 3.0 and four DDR3 memory controllers. AMD’s twelve-core processors were launched at the end of March 2010, but servers based on these “Magny-Cours” Opterons were hard to find. So for a few months, Intel dominated the midrange and high-end server market. HP and Dell informed us that they would launch the "Magny-Cours" servers in June 2010. That is history now, and server buyers have an alternative again for the ubiquitous Xeon Servers.
AMD’s strategy to make their newest platform attractive is pretty simple: be very generous with cores. For example, you get 12 Opteron cores at 2.1GHz for the price of a six-core Xeon 2.66GHz (See our overview of SKUs). In our previous article, we measured that on average, a dual socket twelve-core Opteron is competitive with a similar Xeon server. It is a pretty muddy picture though: the Opteron wins in some applications, the Xeon wins in others. The extra DDR3 memory channel and the resulting higher bandwidth makes the Opteron the choice for most HPC applications. The Opteron has a small advantage in OLAP databases and the virtualization benchmarks are a neck and neck race. The Xeon wins in applications like rendering, OLTP and ERP, although again with a small margin.
But if the AMD platform really wants to lure away significant numbers of customers, AMD will have to do better than being slightly faster or slightly slower. There are many more Xeon based servers out there, so AMD Opteron based servers have to rise above the crowd. And they did: the “core generosity” didn’t end with offering more cores per socket. All 6100 Opterons are quad socket capable: the price per core stays the same whether you want 12, 24 or 48 cores in your machine. AMD says they have “shattered the 4P tax, making 2P and 4P processors the same price.”
So dual socket Opterons servers are ok, offering competitive performance at a slightly lower price, most of the time. Nice, but not a head turner. The really interesting servers of the AMD platforms should be the quad socket ones. For a small price premium you get twice as many DIMM slots and processors as a dual socket Xeon server. That means that a quad socket Opteron 6100 positions itself as a high-end alternative for a Dual Xeon 5600 server. If we take a quick look at the actual pricing of the large OEMs, the picture becomes very clear.
Compared to the DL380 G7 (72GB) speced above, the Dell R815 offers twice the amount of RAM while offering—theoretically—twice as much performance. The extra DIMM slots pay off: if you want 128GB, the dual Xeon servers have to use the more expensive 8GB DIMMs.


Last night, when the wind picked up, promising heat and dryness and itching skin and crunchy nose today, I stepped outside to look at it. I saw clear air and shiny leaves and the tiniest Pleiades ever…but it was the Pleiades…in Southern California…a rare sight indeed. I was floored. And I was grateful.
The tiny things represent big things. The tiny accumulate into big.
A lot of crap and exhaustion and stress today. But…I saw the Pleiades.


A pseudotree is a connected graph which has exactly one cycle and no self-loops. Note that a pseudotree may contain multiple-edges. It can be shown that a pseudotree with $$$n$$$ vertices always contains $$$n$$$ edges.

After deleting all edges on the cycle in the pseudotree, a forest$$$^{\dagger}$$$ will be formed. It can be shown that each tree in the forest will contain exactly one vertex which is on cycle before removing the edges. If all trees in the forest have the same depth$$$^{\ddagger}$$$ when picking the vertex on cycle as root, we call the original pseudotree flower-like.

Our friend sszcdjr, had a flower-like pseudotree with $$$n$$$ vertices and $$$n$$$ edges. However, he forgot all the edges in the pseudotree. Fortunately, he still remembers the degrees of vertices. Specifically, the degree of the $$$i$$$-th vertex is $$$d_i$$$.

You have to help sszcdjr construct a possible flower-like pseudotree with $$$n$$$ vertices, where the degree of the $$$i$$$-th vertex is exactly $$$d_i$$$, or tell him that it is impossible.

$$$^{\dagger}$$$ A forest is a graph in which all connectivity components are trees. A connected graph without cycles and self-loops is called a tree.

$$$^{\ddagger}$$$ The depth of a tree with a root is the maximum distance from the root to the vertex of this tree.


I am making an open-source software that is an alternative version of another very popular software, Postman. The inspiration reflects mainly on user interface and concepts. No source code was copied from this software, I wrote my own entirely.
I searched about copyright licenses and their terms of service say (Section 8):
You and your Users shall not: (...) create any derivative works based on the Services;
and also (Section 4):
You acknowledge and agree that Postman (...) have and retain all legal right (...) in the Services including but not limited to any ideas, concepts, inventions, systems, platforms, interfaces, tools, utilities, user interface, algorithms, logic, formula, scripts, work flows, processes, software, (...)
However, it gets more complicated because some parts of their code are open-source on GitHub, under Apache license.
This related question answer argues that "Copyrights are about the actual source code, not about the ideas/concepts that are represented in that source code."
Am I infringing their license by creating my software?
