| Prev | Up | Chapter 11. Indexes | Next |
An index definition can specify an operator class for each column of an index.
CREATE INDEX name ON table (column opclass [sort options] [, ...]);
The operator class identifies the operators to be used by the index for that column. For example, a B-tree index on the type int4 would use the int4_ops class; this operator class includes comparison functions for values of type int4. In practice the default operator class for the column's data type is usually sufficient. The main reason for having operator classes is that for some data types, there could be more than one meaningful index behavior. For example, we might want to sort a complex-number data type either by absolute value or by real part. We could do this by defining two operator classes for the data type and then selecting the proper class when making an index. The operator class determines the basic sort ordering (which can then be modified by adding sort options ASC/DESC and/or NULLS FIRST/NULLS LAST).
There are also some built-in operator classes besides the default ones:
The operator classes text_pattern_ops, varchar_pattern_ops, and bpchar_pattern_ops support B-tree indexes on the types text, varchar, and char respectively. The difference from the default operator classes is that the values are compared strictly character by character rather than according to the locale-specific collation rules. This makes these operator classes suitable for use by queries involving pattern matching expressions (LIKE or POSIX regular expressions) when the database does not use the standard "C" locale. As an example, you might index a varchar column like this:
CREATE INDEX test_index ON test_table (col varchar_pattern_ops);
Note that you should also create an index with the default operator class if you want queries involving ordinary <, <=, >, or >= comparisons to use an index. Such queries cannot use the xxx_pattern_ops operator classes. (Ordinary equality comparisons can use these operator classes, however.) It is possible to create multiple indexes on the same column with different operator classes. If you do use the C locale, you do not need the xxx_pattern_ops operator classes, because an index with the default operator class is usable for pattern-matching queries in the C locale.
The following query shows all defined operator classes:
SELECT am.amname AS index_method, opc.opcname AS opclass_name FROM pg_am am, pg_opclass opc WHERE opc.opcmethod = am.oid ORDER BY index_method, opclass_name;
An operator class is actually just a subset of a larger structure called an operator family. In cases where several data types have similar behaviors, it is frequently useful to define cross-data-type operators and allow these to work with indexes. To do this, the operator classes for each of the types must be grouped into the same operator family. The cross-type operators are members of the family, but are not associated with any single class within the family.
This query shows all defined operator families and all the operators included in each family:
SELECT am.amname AS index_method, opf.opfname AS opfamily_name, amop.amopopr::regoperator AS opfamily_operator FROM pg_am am, pg_opfamily opf, pg_amop amop WHERE opf.opfmethod = am.oid AND amop.amopfamily = opf.oid ORDER BY index_method, opfamily_name, opfamily_operator;

This tour is packed with places which represent the essential Tokyo. We do not simply go from site to site; our planned route visits each of the Shibuya ward’s most famous areas in a clear but not straight path, which makes you feel like you are really exploring Tokyo both on the main and back streets.
Instead of just walking and looking at each attraction as an outsider, we will enter each location as a new step of our adventure. Naoki and Kevin will take one step further to separate ourselves from other tours; you’re not just another customer to us.
Tokyo is a huge and complicated city. You can’t learn everything about Tokyo’s appeal and beauty just from looking at a guidebook.
We want to introduce the real, local Tokyo even in the middle of the most well-known tourist sites.
Let’s go together to those deep parts only the real Tokyo people know.
After going on this tour, you can really say ‘I came to Tokyo!’ with confidence.
The place of origin for Japan's latest "kawaii bunka" (cute fashion) trends, Takeshita Street is the heart of Harajuku. While typically thought of a hub for young people's fashion shopping, it is also lined with many interesting stores with a unique character only found here. Always a prime spot for people watching, you'll be amazed at the variety of strange sights and characters.
Behind the bustling Takeshita Street you'll find an area that mixes the sophisticated edge of nearby Omotesando with the youth and experimentalism of Takeshita Street. The Festa Art Gallery and Cafe is a work of art in itself, and a haven for young artists who display their work for free. The area even features a mega-sized work by famous British street artist Banksy.
Near the end of Takeshita Street we'll find the entrance to a different shopping atmosphere, not one of youthful experiment but one of mature sophistication. Chanel, Louis Vuitton, Gucci - high-end brands from all over the world line the streets. While a go-to shopping area for Tokyo high society, it is also loves by tourists from around the world and thus holds its own as an international site.
Compared to the bright and crowded Takeshita Street, Cat Street is a cool and tasteful area aimed not at teenagers but at yuppies who enjoy a hipster style not found on either Takeshita nor Omotesando street. With its own share of unique stores and cute cafés, Cat Street offers a taste of local flavor.
You wouldn't be wrong to say the Shibuya Crossing is one of the most visited tour spots in Tokyo, if not the most. Every day, people are overwhelmed by the sheer number of pedestrians, with over 500,000 per day, a Guinness world record. However, we will also lead you to the parts of Shibuya almost none of the tourists know, which only the real residents venture to.
Far from the chain stores to be found in any major city, Tokyo also boasts a strong coffee culture not to be diminished by Japan's long history of tea drinking. The baristers at our selected shop select only the best roasts and serve them with expertise. You'll be able to take a refreshed step back into the busy Tokyo streets.

Since my last post on this there have been quite a few conversations had on twitter and we’ve now got Kenna’s blog post with additional details on their methodology.
I’m not going to try and cover the whole Top 10 but I think it’s worth looking at what Kenna have mentioned specifically with regards to the two FREAK vulnerabilities that I looked at last time. From Kenna’s blog post they define “Successful Exploitation” as
Successful Exploitation is defined as one successful technical exploitation of a vulnerability on one machine at a particular timestamp. The event is defined as:
1. An asset has a known CVE open.
2. An attack come in that matches the signature for that CVE on that asset and
3. One or more IOCs are detected/correlated post attack
The “mystery sauce” here is part 3 around IOCs to detect a successful exploit, as that’s tricky to do with a MiTM attack like the two FREAK CVEs. Attackers who successfully exploited that may just intercept sensitive data from the connection and them misuse it elsewhere, which is virtually impossible to correlate.
Kenna also provided some interesting graphs for these vulns here and here which show large spikes of activity initially followed by periodic smaller spikes through the year.
Now, to me, that doesn’t really seem to fit a real attack on this issue as I kind of doubt that many people have the ability to crack 800k even weak RSA keys at once, also if someone had compromised that volume of SSL connections in a short space of time you’d have thought there would’ve been some fallout from it…
However, what it does match is someone running a scanning tool over the large parts of the Internet looking for this vulnerability. A scanning tool for this will negotiate a connection using the weak RSA keys, that’s how they work.
Looking at the graph for CVE-2015-0204, we can see a …. huge spike in activity around March 2015, when… the researchers for the FREAK attack did a large scan looking for the issue. Looking at the Freak Attack page we see a note
The following sites from the Alexa Top 10,000 websites permit RSA_EXPORT cipher suites, which potentially puts their users at risk from the FREAK attack. This list is current as of March 10 at 8:00 AM EST.
indicating that they did a big scan in March 2015 which roughly correlates with the big spike in Kenna’s graph. I’d also guess that a lot of other researchers would scan around that time as it was when the vulnerability was released.
So whilst I can’t be really sure, if I was a betting man, I’d suggest that Kenna’s data doesn’t point to a sophisticated attacker exploiting an SSL MITM issue, but to a group of security researchers scanning a large number of sites after they had announced their vulnerability.
The only mystery then is “what was the IOC seen on the affected hosts?”.

I'd like to report what appears to be a new way of taking Calea. I've found no references to this method on the web. It's a very efficient method since it requires very little herb to achieve strong effects. Also, it's a lot healthier than smoking. The disadvantage of the method is, of course, the intensely bitter taste of the herb (which for me, is not a big problem).
The use of Salvia Divinorum in tincture form is well known. I was wondering if Calea tincture would be similarly effective.
A report on Erowid mentions an ethanol extract of Calea. Its author claims that the extract is at least five times stronger than tea made from the same amount of herb. He recommends drying the extract and inserting it in capsules.
Per his instructions, I mixed four tablespoons of crushed dried Calea herb with twice its volume of Everclear 195-proof alcohol. The mixture was shaken once a day and allowed to sit for five days. After the fifth day, the ethanol tincture was separated from the herb using a filter. This resulted in about eight teaspoons of Calea tincture.
I then mixed one teaspoon of the tincture with enough water to comfortably hold in my mouth (about 12 teaspoons), and added a drop of peppermint extract and some honey. As in the Salvia tincture method, I held the mixture in my mouth for fifteen minutes, periodically swooshing the liquid around and making sure that it reached underneath my tongue (where the sublingual mucous membranes absorb the psychoactive substances). Given the very strong bitterness, this was no mean task, but listening to some classical music distracted me from the taste.
After fifteen minutes, I began to feel the now-familiar initial effects of a good Calea dose: closed-eye visuals and increased hypnagogic imagery. With some effort, I swallowed the liquid in my mouth. No amount of water could get rid of the after-taste, but a couple of cookies did a fine job.
I went upstairs to take a shower. In the bathroom, the closed-eye visuals were reaching a pleasant intensity, as strong as that from the tea + cigarette method, minus the irritated lungs. Ten minutes later, I was under the bedsheets. In the darkness, I enjoyed strange hypnagogic imagery: undulating serpents whose heads are flowers, bizarre ornamented ears, lizards transforming into fish and vice versa, mysterious psychedelic plants growing in 'fast forward', and a lot of other stuff that's hard to describe or remember.
I woke up towards dawn after a very vivid dream. As I was trying to sleep again, I thought about the dream. I interpreted it as expressing a fear of being left in the lurch at work. Unfortunately, when I got out of bed much later, I couldn't remember anymore what the dream was about!

What I Like to Photograph
I take these photos to recall memories I had with the pictures. The main pictures I like to take are of my family and friends. I take these photos to recall memories I had with the pictures. Later on, I plan to compile these photos and make an album to reminisce throughout my life. My family would often make albums of their children when they were younger, and I want to do the same, but throughout life.
I also like to take pictures of animals and nature. Most of my pictures of cats that I find throughout my neighborhood. Unfortunately, most of the pictures are blurry since they run away. Aside from that, I also like to take pictures of nature and scenery. Looking back on these pictures make me feel at peace. I would like to make an album in the future to revisit all the views I have seen throughout my life.

I started the day off by working on my portfolio for the Google SPS program. Since I was thinking about what I should put throughout the week, the inputting the text was not too difficult. Once I arrived at school, I went to retrieve the homework I needed to grade over the weekend. I then studied a bit more for my quiz for one of my classes today and organized one of my organization's drive as a proposal to help with managing files before I headed to class. I then reviewed a pull request for my research project and continued to study for my quiz. Afterwards, I went to class then worked more on the SPS portfolio website while waiting for my fifth class. Once my fifth class finished, I worked more on the SPS portfolio website since the cloudshell wasn't saving the changes I was making in the afternoon. I then went to one of my club meetings for a major summit event we are planning the first Friday of March of 2020. I then finished most of the SPS website at this point since I found out that my error was me changing the wrong files. Before going to bed, I made minor adjustments to my flutter mobile research project and created logos for one of the organization I am in.

Starting my day at 4am, I went to work and had to reinstall all of my software on my new computer with another individual. I was able to finish a task given to me and submitted a pull request while also finishing half way of another task. Afterwards, I went to run errands then returned home at 7pm. Then, I worked on my research project to make small adjustments to the design. Since there was not much communication within my group, I began to look into some of the code written by others to modify for future reference. Later on, I created pull request which was accepted. Later on, I made other minor adjustments before studying for my quiz until 10pm.

At the start of the day, I started to finalize my features for flutter mobile research project. I was able to create my nutritonal calculator before my first class. Afterwards, I worked three hours on my mobile project finalizing the embedded website and the additional screen. Then, I went to my classes and began installing my environment for my software engineering Flask inventory tracking system project. Exhausted from programming five hours while studying for classses, I slept early this day in preparation of my work at 4am the following day.

昨天開始，EpicDice暫時停止營業，官方discord宣布如下
@everyone, we have good news and bad news for you.
The bad news is, after some in-depth investigation we concluded our game is exploited due to we are using the simplest provably-fair mechanism. All the game result is solely relying on the blockchain transaction ID. We thought it was random and hard enough for bad actors to game the system but apparently, it wasn’t. We will have to halt the platform until a new mechanism is being implemented, and this is going to be the team’s top priority now.
The good news is, the house fund wasn’t completely drained so we are ready to come back strong as soon as the system is patched. And for those who previously suspect EpicDice is not playing fair, this is the best(or worst) example to prove our claim: Absolute fairness. Even in such event where the randomness of transaction ID is exploited, house is on the vulnerable side. We were truly running the best ever gambling service in term of everything we can.
This is not the end. We will come back stronger and better. Thanks for the support.
簡而言之 (本來寫比較長，但被SCT的submit系統搞丟文章 >_<)，被人利用算法機制的弱點突破了。
好奇的話，你可以參考這一篇：Epic Dice shut down due to witness cheating
簡單說一下，事情是這樣的。有位見證人mys，找出ED利用Steem txid產生數字過程的瑕疵，利用見證人的方便，送出自己希望的txid，大量用1 STEEM左右，贏得100 STEEM，大約進行27次後，被人舉報，平台因此暫停檢視，發現此一重大漏洞。
此事其實證明了團隊宣稱的fairness，亦即莊家與玩家都是平等的。只是這次，被掌握出塊的見證人以及略欠周詳的掌握txid產生過程細節不足，導致這個重大問題浮出檯面。其實是好事，我覺得。要長成大樹，就要接受風雨的摧殘嘛~~~~
所以，停機檢修，重新研發更好的流程，這團隊還是值得期待的。
如果你是對Steem區塊鏈運作很熟悉的高手，歡迎提供團隊好的建議，如何找出一個不能被單一或數位見證人操弄，而又具有亂數性質的數字來源呢？
歡迎挑戰! 有想法可以告訴我或是 @fr3eze，我個人提供 30 STEEMs 作為獎勵，如果你的想法被採納或是對於最後採納的方案有所幫助都可以 (由ED團隊認定)！

Morena Milani, 53, was sentenced in Victoria's County Court on Monday to a maximum 3½ years behind bars after she pleaded guilty to the grooming, sexual assault and penetration of the teenager.
The court heard the married mother-of-two began pursuing the teenager in March 2018, saying she was concerned about his mental health.
Within months, she was texting him "practically every day, practically all the time", the teenager told later police.
"Sometimes it would turn into, like, sexual things", he said.
Almost 15,000 text messages and emails were exchanged between June 19 and August 10, with thousands of references to "sex, sexual acts, sexual fantasies and pornography".
On his 15th birthday, Milani took the teenager to a Lake Mountain ski resort, where they played in the snow, drank cider and ate pizza.
On the trip, she allowed him to drive her car, despite being unlicensed, at 110km/h.
She also took the teenager to bars across Melbourne, engaged in tickle fights and gave him gifts.

There were plans to escalate the sexual activity during a trip to a country cottage, booked for late August.
Police became involved when the teenager's parents became aware of the large number of text messages, emails and phone calls he was receiving.
When Milani was arrested in November, police also uncovered a statement falsely accusing the teenager of sexual assault in an effort to hide her offending.
Judge Peter Lauritsen said the social worker, who started her own life-coaching business in 2011, had a "significant understanding of vulnerabilities and cognitive abilities of young people".
"Given your academic and occupational experience, you should've realised the harm your sexual activity would cause to the complainant and his family," he said, adding the psychological damage to the teen will "persist for the foreseeable future".
He said he took into account Milani's remorse, noting she had read a statement to the court apologising to her victim and his parents.
Her offending was attributed to her deteriorating mental health and alcohol abuse at the time.
She did not meet the boy through her job, and her former employer released a statement confirming she had no contact with children through her social work.
Milani will have to serve two years and two months of her sentence before being eligible for parole.

On July 22nd, the Cubs designated second baseman Darwin Barney for assignment. This meant that the Cubs would have to trade or place Barney on waivers within 10 days or he would be released. On Monday, the Cubs found a trading partner, sending the former Gold Glover to the Los Angeles Dodgers for a player to be named later. That player was announced this afternoon.
The Cubs acquired 20 year old, right handed pitcher Jonathan Martinez. The right hander has pitched this year in Low A Great Lakes in the Midwest League. Martinez has pitched in 19 games for the Loons this year, starting all of them, while compiling a 3.47 ERA in 106.1 innings. The 20 year old has only walked 19 batters in that span while striking out 91 and posting a career high 4.79 strikeout to walk ratio. Martinez will likely land in Low A Kane County, which will put him back in the Midwest League. Last week, the righty was ranked as the number 19th prospect in the Dodgers organization by dodgersdigest.com. Here is what the site said about Martinez:
19. Jonathan Martinez, RHP (Ranked in Pre-Season list: 35, +16)
Started: Low-A Great Lakes
Current location: Great Lakes
- Martinez had a rough 2013 season split between Ogden and Great Lakes. This season, he’s basically the Loons’ ace and has posted a couple of really stellar performances, including a 6-inning, 2-hit, 11-strikeout game to start his 2014 season. He has great command, as he has a career-best 1.4 BB/9 and has increased his strikeout rate from 5.7 per nine last year in Midland to 7.7 this year. He could get a call to Rancho if someone there is promoted. If not, he’ll be there next year.

The NameValueTree is a very important utility class in this library. It is used whenever a dynamic linked list is required. This actually not just a list but a tree, that is each element not only has neighbors but also childs. This tree-like structure allows the list class to take care of XML constructs. There is a method to convert a list into BEEP XML format and vice versa.
This list object is utilized more or less whenever there is need for a dynamically assigned structure. Some examples are
As such, the class should be highly optimized. The list is only single-linked as - as of now - we do not see any reason to walk the list backwards or delete a list entry in the middle. Using single links saves some storage as well as CPU cycles in this case.
The list actually consists of two data structures:
The list provides keyed access. A list can be searched based on a string or unsigned key. Each entry provides string or unsigned values to this key. Each entry can have on void* pointer to point to whatever larger data type the caller may need.
If XML is represented, a true tree is build. The hierarchie reflects the nesting of XML elements.
The same rules are used to persists a NameValueTree to XML.

Add an entry to the end of a NameValueTree List. A new entry element is constructed and added onto the end of the list.
|
|
|
Print out a whole tree structure. This is a debug aid and ONLY AVAILABLE IN DEBUG BUILDS! We walk the tree and call ourselfs recursively.
|
|
|
Construct a NameValueTree Entry Object. Use this constructor whenever a new object is created!
|
|
|
Destructor for entry elements. This destructor destroys all elements directly associated with this entry element. As such, XML Properties and Childs are destroyed, but not the parent or sibling, as they may remain valid in another context. If there is a user pointer, the supplied free() function is called on it. |
|
|
Return the uValue for this object. If the uValue is already set, it is returned. If it is not yet set, we look at the szValue and see if we can convert it to an uValue. If that succeeds, we return the converted value. If that does not succeed, -1 is returned and an error is flagged.
|
|
|
Link a child list to the current entry.
|
|
|
Set the string key for a given entry. The string key is copied to a new buffer if so requested.
|
|
|
Set the integer key for a given entry.
|
|
|
Set the user pointer for a given entry.
|
|
|
Set the string value for a given entry. The string key is copied to a new buffer if so requested.
|
|
|
Set the integer value for a given entry.
|
|
|
Unlink an entry from the current list.
|
|
|
Remove the user point from an element. This is needed if the element got deleted by the user itself. If not done, the list destructor would try to delete the object, thus resulting in a double-free. If the user pointer is not set, nothing happens. |
|
|
Duplicate a string and return it. This is a general utility, it was just defined first in the context of NVTE.
|
|
|
Construct a NameValueTree Root Object. Use this constructor whenever a new object is created!
|
|
|
Destructor for root elements - destroys a complete list. So we need to walk it by using the raw pointers. |
|
|
Checks if a list has the named element. Can also check if it is the only element in the list.
|
|
|
Populate a NameValueTree based on a BEEP XML stream. This is a mini BEEP XML parser. It parses those constructs supported by BEEP XML. It does NOT check the DTD, this needs to be done by the caller. This is a "one stop" method, which means that it will do anything needed to do the job. The method detects syntax errors, only. If one is detected, an error state is returned. In this case, the status of the provided NameValueTree structure is undefined - probably some elements have been added, others not. It is highly recommended that the caller discards the NameValueTree structure if this method does not return error-free. If a pre-populated NameValueTree is provided, the elements found in the XML stream are ADDED to it. This is a single-pass parser. ABNF for our Mini XML Parser:

|
|
Removes the first entry from a list. The entry will be unlinked and then destroyed. It is valid to call this function on an empty list. In this case, nothing will happen. |
|
|
Remove a keyed entry from a root element. The key search is done on the unsigned key. The first entry with a matching key value is removed. Do not use this method on a list with potentially multiple keys of the same value - or be sure to know EXACTLY what you are doing and why... The entry shall not only be unlinked from the tree but also destroyed. |
|
|
Remove an entry with a specific pUsr from a root element. The first entry with a matching pUsr is removed. Do not use this method on a list with potentially multiple identical pUsrs - or be sure to know EXACTLY what you are doing and why...
|
|
|
Unlinks a root element (complete list) from its parent. If the root element has no parent, nothing happens. This is no error. |
|
|
Find the next element with a given string key inside the list.
|
|
|
Find the next element with a given integer key inside the list.
|
|
|
This is more or less a duplicate of the sbNVTSearchKeyU. The difference is that this method also delivers back the previous entry. This is done for performance reasons - it saves us from doubly-linking the list, which would otherwise be required and for sure be overdone in the current state of affairs. AllParams are like sbNVTSearchKeyU plus

Unlink the first element from a name value tree. The element is not destroyed, but simply unlinked.

XML-Escape a string. The resulting string is suitable for use in #pcdata, that is as a string BETWEEN XML tags (e.g. string. It is NOT suitable to be used inside a tag parameter (e.g. ).

Detailed Description
The QSGOpaqueTextureMaterial class provides a convenient way of rendering textured geometry in the scene graph.
Warning: This utility class is only functional when running with the OpenGL backend of the Qt Quick scenegraph.
The opaque textured material will fill every pixel in a geometry with the supplied texture. The material does not respect the opacity of the QSGMaterialShader::RenderState, so opacity nodes in the parent chain of nodes using this material, have no effect.
The geometry to be rendered with an opaque texture material requires vertices in attribute location 0 and texture coordinates in attribute location 1. The texture coordinate is a 2-dimensional floating-point tuple. The QSGGeometry::defaultAttributes_TexturedPoint2D returns an attribute set compatible with this material.
The texture to be rendered can be set using setTexture(). How the texture should be rendered can be specified using setMipmapFiltering(), setFiltering(), setHorizontalWrapMode() and setVerticalWrapMode(). The rendering state is set on the texture instance just before it is bound.
The opaque textured material respects the current matrix and the alpha channel of the texture. It will disregard the accumulated opacity in the scenegraph.
A texture material must have a texture set before it is used as a material in the scene graph.

10 JSON-RPC over TCP
The program in this example is built on top of two Cminor system libraries:
the System.Net.Sockets library and
the System.Json library.
10.1 System.Net.Sockects Library
The sockets library contains minimal functionality contained by the following classes
most of which are found also in the .NET Framework:
-
TcpSocket class represents a TCP socket.
-
TcpListener class is for listening and accepting connections to a TCP port.
-
TcpClient represents an endpoint of a TCP connection.
-
NetworkStream is used to send and receive data over a TCP connection.
Here's the interface of the System.Net.Sockets library:
10.2 System.Json Library
This library contains classes for representing JSON data, a JSON parser, and classes for implementing the JSON-RPC 2.0 protocol over a TCP connection.
The following classes are for representing JSON data:
-
System.Json.Value class acts as an abstract base class of concrete JSON value classes.
-
System.Json.String class contains a JSON string.
-
System.Json.Number class contains a JSON number.
-
System.Json.Object class holds a map of JSON strings mapped to JSON values.
-
System.Json.Array class holds an array of JSON values.
-
System.Json.Bool represents a JSON truth value.
-
JSON null value is represented by null.
Here's the interface of the JSON data classes:
The ParseJsonText parses a JSON string and returns the corrensponding JSON value derived from the System.Json.Value class.
Each JSON value class override the ToString() member function that serialize the value as a string.
The following classes are for implementing the JSON-RPC 2.0 protocol:
-
System.JsonRpc.Exception is the base class of protocol error exception classes.
-
System.JsonRpc.InvalidRequest exception is thrown on invalid request.
-
System.JsonRpc.MethodNotFound exception is thrown when no method of given name is registered with TcpServer.
-
System.JsonRpc.InvalidParams exception is thrown by the application class when there is error with request parameters.
-
System.JsonRpc.Request class is for constructing a JSON-RPC request.
-
System.JsonRpc.Response class is for constructing a JSON-RPC response.
-
System.JsonRpc.Servant class is an abstract base class for JSON-RPC method implementation classes.
-
System.JsonRpc.Client class is an abstract base class for JSON-RPC client implementation classes.
Here's the interface of the JSON-RPC classes:
The following classes implement the JSON-RPC 2.0 protocol over a TCP connection:
-
System.JsonRpc.TcpClient class implements the client side of the JSON-RPC 2.0 protocol with the help of a class derived from the
System.JsonRpc.Client class.
-
System.JsonRpc.TcpServer class implements the server side of the JSON-RPC 2.0 protocol with the help registered servant classes derived from
the System.JsonRpc.Servant class. The server starts a thread for serving each client connection so it's not suitable as a real TCP service
implementation.
Here's the interface of the JSON-RPC TCP classes:
10.3 Server Program
Here's an example implementation of a JSON-RPC 2.0 server that evaluates arithmetic expressions:
The server listens by default port 8080 and serves requests to evaluate method.
10.4 Client Program
Here's an example implementation of a JSON-RPC 2.0 client that gets arithmetic expressions from user, converts them to JSON-RPC requests and shows retrieved results:
10.5 Example Communication
Here's an example of compiling the solution and running the server program:
> cminor build --native JsonRpcCalc.cminors
> cminor run --native assembly/debug/JsonRpcServer.cminora --log
press CTRL-C to end...

[gecode-users] How to use Gecode binaries from within MSVC's IDE
Christian Schulte
cschulte at kth.se
Mon Aug 25 16:41:00 CEST 2008
Dear all,
thanks to the help from Jan Kelbel, we found a solution (well, workaround)
for using the precompiled binaries we ship within Microsoft Visual Studio's
Integrated Development Environment (IDE).
The IDE defines the macros UNICODE and _UNICODE: when compiling with these
macros set, things crash. What you can do is the following:
- Go to the project property dialog
- Find the entry "Configuration Properties"
- Find the section "General"
- Switch "Character Set" to "Use Multi-Byte Character Set"
That should do the trick. We will investigate further what happens exactly
with UNICODE and _UNICODE defined (it's so not documented... Aaaaargh!).
Cheers
Christian

Skylar Carson, a junior at Steamboat Springs High School in Colorado, was horrified when she and her fellow 16 and 17 year-old classmates were asked to study Howl, a controversial 1950s work by Beat poet Allen Ginsberg.
The lengthy poem, which is split into three parts, discusses the self-destruction of the author’s friends, ‘with drugs, alcohol and cock and endless balls’.

Ginsburg also references a ‘vision of the ultimate c**t’, with the poem filled with visceral images of drug-taking and violence.
Skylar was stunned by the work, which she and her classmates had to read aloud, and told Fox31: ‘The second we started reading the book it just went south

‘It was so filled with sexual content that I wasn’t aware of and I wasn’t prepared for.’
Skylar said no warning was given by teachers about the poem’s contents, with her dad Brett also outraged.
He said: ‘She came home and shared it with us and of course as a parent the way we’ve raised our kids I was like, there’s no way a teacher in a public school would have done this.’
Brett says parents should have been informed their children were going to study an explicit work, and be given the chance to opt out of it.
He added: ‘A lot of the kids, you know, were scared to say anything to their parents because it was so awkward and just weird.’
Skylar’s teacher has since apologized, admitting students and parents felt ‘blindsided’ and that they should have been ‘exceedingly clear’ about the content of Howl before starting.
Steamboat Springs School District permits the teaching of controversial works, but rules state parents may have to be informed beforehand.
They say the poem has now been removed from its curriculum, and also apologized for not giving advance notice about its content.
The Carsons have hired religious liberty attorney Jeremy Dys.
He has demanded that all parents receive a letter of apology from the teacher, and that the school undertake sensitivity training to avoid a repeat.

Howl was published when gay sex was illegal in all 50 US states, and sparked an obscenity trial in 1957, the year after it was published.
The presiding judge, Clayton Horn, ruled the book was not obscene, and said there was no point in ‘freedom of press or speech if one must reduce his vocabulary to vapid innocuous euphemisms.’
Ginsberg became one of the most lauded poets of his generation, and died in New York in 1997 aged 70.

Rigid bodies
A rigid body is an extended area of material that includes all the points inside it, and which moves so that the distances and angles between all its points remain constant. The location of a rigid body can be described by the position of one point $P$ inside it, together with the rotation angle of the body (one angle in 2D, three angles in 3D).
| location description | velocity description | |
|---|---|---|
| point mass | position vector $\vec{r}_P$ | velocity vector $\vec{v}_P$ |
| rigid body in 2D |
position vector $\vec{r}_P$
angle $\theta$ |
velocity vector $\vec{v}_P$
angular velocity $\omega$ |
| rigid body in 3D |
position vector $\vec{r}_P$
angles $\theta,\phi,\psi$ |
velocity vector $\vec{v}_P$
angular velocity vector $\vec{\omega}$ |
Neither point masses nor rigid bodies can physically exist, as no body can really be a single point with no extent, and no extended body can be exactly rigid. Despite this, these are very useful models for mechanics and dynamics.
Rotation angles for rigid bodies
All points on a rigid body have the same angular rotation angles, as we can see on the figure below. Because the angular velocity is the derivative of the rotation angles, this means that every point on a rigid body has the same angular velocity $\vec{\omega}$, and also the same angular acceleration $\vec{\alpha}$.
In 2D the angle $\theta$ of a rigid body the angle of rotation from a fixed reference (typically the $\hat\imath$ direction), measured positive counter-clockwise. The angular velocity is $\omega = \dot\theta$ and the angular acceleration is $\alpha = \dot\omega = \ddot\theta$. The vector versions of these are $\vec\omega = \omega\,\hat{k}$ and $\vec\alpha = \alpha\,\hat{k}$, where $\hat{k}$ is the out-of-plane direction.
Show:
All points on a rigid body rotate at the same rate. Body $\mathcal{B}_1$ is rotated by angle $\theta_1$, so its angular velocity is $\omega_1 = \dot{\theta}_1$, and similarly for the second body.
Warning: Labeling angular quantities on rigid bodies
Angular quantities ($\theta$, $\omega$, $\alpha$) for rigid bodies should not be labeled with points. If $P$ and $Q$ are points on a rigid body, we do not write $\omega_P$ or $\omega_Q$ for the angular velocity about these points.
Instead, we label angular quantities according to the body. If we have two rigid bodies $\mathcal{B}_1$ and $\mathcal{B}_2$, then $\omega_1$ is the angular velocity of the first body (and all points on it) and $\omega_2$ is the angular velocity of the second body.
Rotations in 3D are significantly more complicated than rotations in 2D. Unlike positions, velocities, etc, which simply go from 2D vectors to 3D vectors, rotational quantities go from scalars in 2D to full 3D vectors in 3D. Angular velocity and angular acceleration are somewhat straightforward, so equations #rkg-er hold in both 2D and 3D, but understanding the rotations themselves is significantly more complicated. There are three main ways that 3D rotations can be represented:
Detailed study of rotations in 3D is necessary for a full understanding of topics ranging from satellite attitude control to articulated robot construction, and is usually covered in advanced dynamics courses.
Points on rigid bodies
If we know how one point $P$ on a rigid body is moving and we also know how the body is rotating, then we can calculate the movement of any other point $Q$ on the same body. The formulas for this are given below.
Rigid body point relations.
\[\begin{aligned} \vec{r}_Q &= \vec{r}_P + \vec{r}_{PQ} \\ \vec{v}_Q &= \vec{v}_P + \vec{\omega} \times \vec{r}_{PQ} \\ \vec{a}_Q &= \vec{a}_P + \vec{\alpha} \times \vec{r}_{PQ} + \vec{\omega} \times (\vec{\omega} \times \vec{r}_{PQ}) \end{aligned}\]
Points $P$ and $Q$ are two locations on a rigid body. Vectors $\vec{\omega}$ and $\vec{\alpha}$ are the angular velocity and angular acceleration of the rigid body.
The first equation is simply the definition of the offset vector $\vec{r}_{PQ}$. Differentiating the first equation gives \[\begin{aligned} \vec{r}_Q &= \vec{r}_P + \vec{r}_{PQ} \\ \dot{\vec{r}}_Q &= \dot{\vec{r}}_P + \dot{\vec{r}}_{PQ} \\ \vec{v}_Q &= \vec{v}_P + \vec{\omega} \times \vec{r}_{PQ}, \end{aligned}\] where the derivative of $\vec{r}_{PQ}$ comes from the rotation formula, given that this offset vector is simply rotating with the rigid body.
If we differentiate again then we obtain \[\begin{aligned} \vec{v}_Q &= \vec{v}_P + \vec{\omega} \times \vec{r}_{PQ} \\ \dot{\vec{v}}_Q &= \dot{\vec{v}}_P + \dot{\vec{\omega}} \times \vec{r}_{PQ} + \vec{\omega} \times \dot{\vec{r}}_{PQ} \\ \vec{a}_Q &= \vec{a}_P + \vec{\alpha} \times \vec{r}_{PQ} + \vec{\omega} \times (\vec{\omega} \times \vec{r}_{PQ}), \end{aligned}\] where we use the fact that $\vec{\alpha} = \dot{\vec{\omega}}$.
Warning: Cross product order
Because cross products are not associative, it is very important to compute the centripetal acceleration term with the parentheses as shown. That is, we must not compute $(\vec{\omega} \times \vec{\omega}) \times \vec{r}_{PQ}$, as this is always zero.
The term $\vec{\omega} \times (\vec{\omega} \times \vec{r}_{PQ})$ in the acceleration equation above is called the centripetal (center-seeking) term, as it is always in the direction $-\vec{r}_{PQ}$ and so acts from $Q$ towards the “center” $P$.
Show: none position velocity acceleration
Two points $P$ and $Q$ on a moving and accelerating rigid body.
Example Problem: Points on a rigid body.
A rectangular block is sliding along the ground so that the contact point $P$ is moving at a constant speed of $3\rm\ m/s$ to the left. The block is rotating clockwise and just before point $Q$ hits the ground the angular velocity is $2\rm\ rad/s$ clockwise and the angular acceleration is $3\rm\ rad/s^2$ clockwise. What is the velocity and acceleration of $Q$ just before impact?
Using the regular $\hat\imath,\hat\jmath$ basis, the known information just before impact is \[ \vec{r}_{PQ} = 2\,\hat\imath \qquad \vec{v}_P = -3\,\hat\imath \qquad \vec{a}_P = 0 \qquad \vec\omega = -2\,\hat{k} \qquad \vec\alpha = -3\,\hat{k}. \] The velocity and acceleration of $Q$ are given by \[\begin{aligned} \vec{v}_Q &= \vec{v}_P + \vec{\omega} \times \vec{r}_{PQ} \\ &= -3\,\hat\imath - 2\,\hat{k} \times 2\,\hat\imath \\ &= -3\,\hat\imath - 4\,\hat\jmath \\ \vec{a}_Q &= \vec{a}_P + \vec{\alpha} \times \vec{r}_{PQ} + \vec{\omega} \times (\vec{\omega} \times \vec{r}_{PQ}) \\ &= 0 - 3\,\hat{k} \times 2\,\hat\imath - 2\,\hat{k} \times (-2\,\hat{k} \times 2\,\hat\imath) \\ &= -6\,\hat\jmath - 2\,\hat{k} \times (-4\,\hat\jmath) \\ &= -8\,\hat\imath - 6\,\hat\jmath. \end{aligned}\]
Example Problem: Coupled rigid bodies.
Three rigid bodies (two rods and a block) are coupled by pins at $O$, $P$, and $Q$ as shown. Body $\mathcal{B}_3$ cannot rotate and must slide horizontally along the ground. The rod lengths are $OP = 3\sqrt{2}\rm\ m$ and $PQ = 5\rm\ m$, and points $O$ and $Q$ are the same height above the ground.
At the instant shown, $\theta_1 = 45^\circ$, $\omega_1 = 4\rm\ rad/s$. What are $\omega_2$ and $\vec{v}_Q$ at this instant?
Taking a regular $\hat\imath,\hat\jmath$ basis at $O$, we can use the rod lengths and angles to find the relative position vectors: \[\begin{aligned} \vec{r}_{OP} &= 3\hat\imath + 3\hat\jmath\rm\ m \\ \vec{r}_{PQ} &= 4\hat\imath - 3\hat\jmath\rm\ m. \end{aligned}\] Using the vector angular velocities $\vec{\omega}_1 = \omega_1\,\hat{k}$ and $\vec{\omega}_2 = \omega_2\,\hat{k}$, we can now use #rkg-er to find first $\vec{v}_P$ and then $\vec{v}_Q$ in terms of the unknown angular velocity $\omega_2$: \[\begin{aligned} \vec{v}_{P} &= \vec{v}_O + \vec{\omega}_1 \times \vec{r}_{OP} \\ &= 4\hat{k} \times (3\hat\imath + 3\hat\jmath) \\ &= -12\hat\imath + 12\hat\jmath{\rm\ m/s} \\ \vec{v}_{Q} &= \vec{v}_P + \vec{\omega}_2 \times \vec{r}_{PQ} \\ &= (-12\hat\imath + 12\hat\jmath{\rm\ m/s}) + \omega_2\,\hat{k} \times (4\hat\imath - 3\hat\jmath) \\ &= (-12 + 3\omega_2)\,\hat\imath + (12 + 4\omega_2)\,\hat\jmath{\rm\ m/s}. \end{aligned}\] The last piece of information that we need to use is the constraint on the motion of $\mathcal{B}_3$, namely that it can only slide horizontally. This can be expressed by saying that the vertical component of $\vec{v}_Q$ is zero, or more generally that the component in the normal direction $\hat{e}_n = \hat\jmath$ is zero. That is: \[\begin{aligned} 0 &= \vec{v}_Q \cdot \hat{e}_n \\ &= \Big((-12 + 3\omega_2)\,\hat\imath + (12 + 4\omega_2)\,\hat\jmath\Big) \cdot \hat\jmath \\ &= 12 + 4\omega_2 \\ \omega_2 &= -3{\rm\ rad/s}. \end{aligned}\] Substituting this back into the expression above for $\vec{v}_Q$ gives: \[\vec{v}_Q = -21\hat\imath{\rm\ m/s},\] which does indeed have no vertical component, as expected.
Warning: Rigid body points may be accelerating even if $\vec{a}_P = 0$ and $\alpha = 0$.
If $\vec{\alpha} = 0$ and $\vec{a}_P = 0$ for a rigid body then we would normally say that the body itself is not accelerating. This does not mean, however, that the points on the bodies are not accelerating. If the body is rotating (so $\vec{\omega} \ne 0$) then the centripetal acceleration means that in fact most points on the body are accelerating at any time.
Rigid bodies in 2D
The #rkg-er equations above are valid in both 2D and 3D. If we know that we are in the 2D $\hat\imath,\hat\jmath$ plane then the angular velocity vector is orthogonal to the plane in the $\hat{k}$ direction and the equations can be written in a simpler form with the perpendicular vector notation #rvv-en, as shown below.
Rigid body point relations in 2D.
\[\begin{aligned} \vec{r}_Q &= \vec{r}_P + \vec{r}_{PQ} \\ \vec{v}_Q &= \vec{v}_P + \omega \, \vec{r}_{PQ}^\perp \\ \vec{a}_Q &= \vec{a}_P + \alpha \, \vec{r}_{PQ}^\perp - \omega^2 \, \vec{r}_{PQ} \end{aligned}\]
Points $P$ and $Q$ are two locations on a rigid body. Scalars $\omega$ and $\alpha$ are the scalar angular velocity and angular acceleration of the rigid body (positive counter-clockwise).
The position vectors $\vec{r}_P$ and $\vec{r}_Q$ lie in the $\hat\imath,\hat\jmath$ plane, so $\vec{v}_P$, $\vec{v}_Q$, and $\vec{r}_{PQ}$ are also in this plane. The angular velocity and angular acceleration vectors are orthogonal and thus can be written: \[\begin{aligned} \vec{\omega} &= \omega\,\hat{k} \\ \vec{\alpha} &= \alpha\,\hat{k}. \end{aligned}\] Evaluating #rkg-er and using the cross-product expression #rvv-e9 now gives the velocity expression: \[\begin{aligned} \vec{v}_Q &= \vec{v}_P + \vec{\omega} \times \vec{r}_{PQ} \\ &= \vec{v}_P + \omega\,\hat{k} \times \vec{r}_{PQ} \\ &= \vec{v}_P + \omega \,\vec{r}_{PQ}^\perp, \end{aligned}\] and the acceleration equation: \[\begin{aligned} \vec{a}_Q &= \vec{a}_P + \vec{\alpha} \times \vec{r}_{PQ} + \vec{\omega} \times (\vec{\omega} \times \vec{r}_{PQ}) \\ &= \vec{a}_P + \alpha\,\hat{k} \times \vec{r}_{PQ} + \omega\,\hat{k} \times (\omega\,\hat{k} \times \vec{r}_{PQ}) \\ &= \vec{a}_P + \alpha\,\vec{r}_{PQ}^\perp + \omega\,\hat{k} \times (\omega\,\vec{r}_{PQ}^\perp) \\ &= \vec{a}_P + \alpha\,\vec{r}_{PQ}^\perp + \omega^2 (\vec{r}_{PQ}^\perp)^\perp \\ &= \vec{a}_P + \alpha\,\vec{r}_{PQ}^\perp - \omega^2 \vec{r}_{PQ}, \end{aligned}\] where we used the fact that $\vec{r}^{\perp\perp} = -\vec{r}$ (two $90^\circ$ rotations make a $180^\circ$ rotation).
If a point $M$ on a rigid body has zero velocity then it is called the instantaneous center of rotation, because the velocity of all points on the body will be given by simple rotation about $M$ with the angular velocity $\vec{\omega}$ of the body. In 2D we can always find the instantaneous center with the following equation, although it might be outside of the physical body.
Instantaneous center of rotation $M$ in 2D.
\[ \vec{r}_{PM} = \frac{1}{\omega^2} \vec{\omega} \times \vec{v}_P = \frac{1}{\omega} \vec{v}_P^\perp \]
Point $P$ has velocity $\vec{v}_P$ and is attached to a rigid body rotating with angular velocity $\vec{\omega}$.
The instantaneous center $M$ has the property that the point on the rigid body at $M$ has zero velocity. We thus want: \[ 0 = \vec{v}_M = \vec{v}_P + \vec{\omega} \times \vec{r}_{PM}. \] Taking another cross product by $\vec{\omega}$ gives: \[\begin{aligned} 0 &= \vec{\omega} \times \Big( \vec{v}_P + \vec{\omega} \times \vec{r}_{PM} \Big) \\ &= \vec{\omega} \times \vec{v}_P + \vec{\omega} \times (\vec{\omega} \times \vec{r}_{PM}) \\ &= \vec{\omega} \times \vec{v}_P - \omega^2 \, \vec{r}_{PM} \text{ (because $\vec\omega \perp \vec{r}_{PM}$)} \\ \vec{r}_{PM} &= \frac{1}{\omega^2} \vec{\omega} \times \vec{v}_P. \end{aligned}\] Here we used the fact that if $\vec{r}_{PM}$ lies in the $\hat\imath,\hat\jmath$ plane and $\vec{\omega}$ is in the $\hat{k}$ direction, then from #rvv-e9 we have $\vec{\omega} \times (\vec{\omega} \times \vec{r}_{PM}) = \omega^2 \,\vec{r}_{PM}^{\perp\perp} = -\omega^2\,\vec{r}_{PM}$, as in the derivation of #rkg-e2.
In 3D there will only be an instantaneous center if $\vec{v}_P$ is orthogonal to $\vec{\omega}$, in which case there will many choices for the instantaneous center, all lying on a line in the $\vec{\omega}$ direction.
If $M$ is an instantaneous center, so it has zero velocity, then the velocity of any other point on the rigid body is given by the following equation.
Velocity from the instantaneous center $M$.
\[ \vec{v}_{Q} = \vec{\omega} \times \vec{r}_{MQ} \]
Point $M$ is the instantaneous center of rotation for a rigid body rotating with angular velocity $\vec{\omega}$, and $Q$ is any point on the body.
By definition the instantaneous center has $\vec{v}_M = 0$, so the velocity formula #rkg-er gives: \[\begin{aligned} \vec{v}_Q &= \vec{v}_M + \vec{\omega} \times \vec{r}_{MQ} \\ &= \vec{\omega} \times \vec{r}_{MQ}. \end{aligned}\]

Regular maintenance, monitoring, and testing can save time and money
Experts estimate that there are nearly one million elevators in the US, each of which serves an average of 20,000 people every year. Elevators don’t just help us get places a little faster – they make dense urban living possible, allowing the efficient construction of high-rise structures all across the world. However, if your property has slow, broken, or otherwise defective elevators, it could be making your life a whole lot less efficient.
If you’re about to move into a new building, ask questions about the elevators
Whether you’ve just signed a lease or you’re weighing several options, it pays to make sure the building’s elevators are in good, working condition. To do that, you’ll have to ask some questions, including how old each elevator is and how often they’re inspected and maintained by a qualified professional. If you haven’t yet leased or bought a property, or you’re on the fence about making a big decision about a building with elevators, you should consider their condition before making your final choice. This is especially the case in particularly tall structures or buildings that may deal with a large amount of elderly or disabled individuals.
If you’re about to move into a new building, ask questions about the elevators
While elevator repairs should only be performed by licensed technicians, building owners and property managers should periodically ride the elevators in each of the buildings that they own and/or manage. These rides can help ensure that smaller issues, such as faulty lights, button wiring issues, or minor door problems are caught early, before they can contribute to an accident or expensive malfunction. Elevator checks also allow owners and managers to identify elevators that are running slowly. While slow elevators might not be much of an issue in a two or three-story building, they can be a serious inconvenience in a 15 or 20-story structure, and could present a safety issue in an emergency.
When it comes to elevators, an ounce of prevention is worth a pound of cure
Statistically, elevators are extremely safe – safer, in fact, than stairs. Nevertheless, maintenance that prevents accidents is essential, and mitigates the possibility of liability for building owners or managers. In addition, regular maintenance helps prevent routine equipment breakdowns, saving time and money in the long run. In addition, the Florida Safety Act stipulates that owners or operators are responsible for ensuring that elevators meet all safety requirements on an annual basis.s.
With 18 billion trips taken in the U.S. each year, elevators are seemingly just as essential to human transport as automobiles. And much like other forms of motorized transportation, they need to be regularly serviced in order to keep them in good working condition.
To learn more about how to make sure your property’s elevators remain an asset instead of a liability, contact Rocket Elevators at<PHONE_NUMBER> or get in touch through our detailed contact information.

--- layout: newsstory title: STUCK IN THIS LEAGUE FOR ANOTHER YEAR match: Yeltz 2 Weymouth 2 ---
Despite bravely fighting back from two goals down, it's now impossible for The Mighty Yeltz to go up this year .
It was a reasonable game all in all. We gave them a two goal start with some awful defending , the second in particular a terrible mix-up between Forrest Gump and Danny.
I must admit we we're on the way to the clubhouse for our usual half-time ablutions when Rob Elmes finally scored his first , but from all accounts he didn't know much about it when the keeper tried to clear the ball only to fire it straight against Elmesey. Still he's deserved one (at least) for his efforts in the last few games.
We had much of the play in the second-half as we pushed for an equaliser, but it took and excellent move and a quality finish from Ada Cooper to get the point a few minutes before the end.
Other news: Evran's court case has been adjourned again, and Catalogue Man scored for Harrow Borough.

--- Day 2: Inventory Management System ---
You stop falling through time, catch your breath, and check the screen on the device. "Destination reached. Current Year: 1518. Current Location: North Pole Utility Closet 83N10." You made it! Now, to find those anomalies.
Outside the utility closet, you hear footsteps and a voice. "...I'm not sure either. But now that so many people have chimneys, maybe he could sneak in that way?" Another voice responds, "Actually, we've been working on a new kind of suit that would let him fit through tight spaces like that. But, I heard that a few days ago, they lost the prototype fabric, the design plans, everything! Nobody on the team can even seem to remember important details of the project!"
"Wouldn't they have had enough fabric to fill several boxes in the warehouse? They'd be stored together, so the box IDs should be similar. Too bad it would take forever to search the warehouse for two similar box IDs..." They walk too far away to hear any more.
Late at night, you sneak to the warehouse - who knows what kinds of paradoxes you could cause if you were discovered - and use your fancy wrist device to quickly scan every box and produce a list of the likely candidates (your puzzle input).
To make sure you didn't miss any, you scan the likely candidate boxes again, counting the number that have an ID containing exactly two of any letter and then separately counting those with exactly three of any letter. You can multiply those two counts together to get a rudimentary checksum and compare it to what your device predicts.
For example, if you see the following box IDs:
abcdef
contains no letters that appear exactly two or three times.bababc
contains twoa
and threeb
, so it counts for both.abbcde
contains twob
, but no letter appears exactly three times.abcccd
contains threec
, but no letter appears exactly two times.aabcdd
contains twoa
and twod
, but it only counts once.abcdee
contains twoe
.ababab
contains threea
and threeb
, but it only counts once.
Of these box IDs, four of them contain a letter which appears exactly twice, and three of them contain a letter which appears exactly three times.
Multiplying these together produces a checksum of 4 * 3 = 12
.
What is the checksum for your list of box IDs?
