You're in a waiting room with one of those "Take a Number" devices. You take your number, sit down, look at it... and find that it's something ridiculous, at least four digits long. Just then, an announcement: "Now Serving, Number Three."
This can end in one of the following ways:
- Every single number before yours is called, but when your number is about to be called... the place closes for the day.
- The waiting room is empty except for you, but the staff insists on calling each number under yours and waiting for a response.
- Hilarity Ensues as you scramble to beg for or steal a lower number.
A common part of this gag is there being a bureaucratic number-system at all at that place (for example, in heaven).
Can also be used as a Stock Phrase to tell someone that they are far from the only one who has a particular request or complaint.
See also Right on Queue, for when a character is stuck in line for a location that doesn't use such a number system. A related trope is Ticket-Line Campout, which is about showing up early to guarantee an early spot in the queue (numbered or otherwise.) Sub trope of Absurdly Long Wait.
Examples:
- An issue of Excalibur has Kitty Pryde getting 10^23 from the dispenser — which is probably a reference to Avogadro's Number.
- In the Belgian comic Arkel, the eponymous angel is seen bringing a recently-departed soul to Purgatorium, where he has to take a number. He gets 800,144, while 309 is called. As Arkel points out, that's only 799,835 numbers to wait, it shouldn't take long.
- This happens at the Torture Place in Retro Chill. The group gets number 5,849,596, and despite being the only people there they have to wait a full day for service.
- Chapter 18 of Pokémon Reset Bloodlines ends with an omake featuring Cameron and his Riolu trying out for the fic in response to casting calls. True to the trope, the two of them end up with the number 750. For added comedy, the duo ends up stuck in between a Dalek and the Major as of number 26 and 27's call up (Jigglypuff and Ritchie).
- In Sonic the Hedgehog in the Fourth Dimension Sonic and Co had to take one before meeting with the Science Council of the Organizers; with was up in the 4000's while the current number called was 24. Needless to say this didn't go down well with one impatient hedgehog.
- Beetlejuice:
- Early in the movie, a ghost couple get a six- or seven-digit number in Heaven's waiting room. It's then revealed that they had to spend three months here before being served.
- At the end, the eponymous ghost gets similarly long number... and is sitting next to the voodoo priest with the next number to be called (4). Betelgeuse tricks him and steals the voodoo priest's number... but gets his head shrunk in retalation.
- In the TV movie High School USA, Beth (Nancy Mc Keon) is working in a bakery when JJ (Michael J. Fox) comes to talk to her. She doesn't want to talk with him and calls the next number. JJ has several "take a number" cards in his pocket and pulls out the correct number so he can talk to her.
- The Tiger Makes Out - Eli Wallach's mad-at-the-world character goes to the housing authority with a grievance on his lunch hour, and gets number 110 when they're only up to 15. He pretends to be #15, but the representative won't talk with him until he's produced the number. He's then busted and booed out of the office for being a line-breaker.
- Get Smart: The entrance to the Kaos base is disguised as a bakery and taking a number opens the secret door.
- Mr. Bean has done the third variant. It is well executed, but pretty much as expected. It basically writes the book on this trope, as Bean explores virtually every possible method to cut his wait short, no matter how cruel. This includes ripping a stuffed animal out of a child's arms to get her out of the line, switching tickets with a woman in a full-body cast which also covers her mouth, drawing a zero on the end of someone else's number, and flipping the digital number readout sign upside down so that 6s appeared to be 9s and so forth. He gets his comeuppance in the end, so despite being one of his cruelest outings ever, it's still all in good fun.
- Chuck: In "Chuck Versus the Imported Hard Salami", Chuck goes to Lou's deli in hope of making up with her. When his number comes up, she tells him that if he's not ordering food he'll have to take another number and wait. Finally, his number comes up at closing time... but he manages to make up with her anyway.
- In the Lost episode "The Lie", Ben arrives at an empty butcher shop, not intending to buy anything, and takes a number. This number (342) has thus been heavily scrutinized by fans.
- Oliver runs into this a couple of times on Green Acres. He draws a high number, while the by-the-book clerk is still in the single digits, and insists on systematically calling every intervening number, even though Oliver is the only customer in the room.
- On The Dukes of Hazzard, Ms. Tisdale, the lady who ran the Hazzard Post Office, is a stickler that everyone has to take a number AND show proper ID for service.
- In Supernatural, after assuming command of the place the demon Crowley turns Hell into a seemingly endless waiting line where the new arrivals quite literally have to pick a number from the adjacent machine and wait their turn. When they reach the front however, they go right back to the beginning.
- In the Saturday Night Live sketch "Samurai Delicatessan", Buck Henry enters the empty (of customers) deli with John Belushi's Samurai behind the counter. When Henry tries to ask for something, the samurai shouts Japanese at him and points (with his katana) at the sign saying "Please take a number." After the samurai calls out three or four Japanese "numbers", Henry calls out that he's got that one and now the samurai waits on him.
- In one MADtv sketch, Ms. Swan asks a criminal collecting protection money to take a number before she will speak to him. He receives number 88, but the Now Serving sign is only at 5. Ms. Swan begins calling all the numbers in between, waiting for a response to each even though they are the only two people in the shop, but she skips to 88 after the racketeer reveals he's a Ms. Swan fan.
- A Chespirito short starring Doctor Chapatín has him arriving at a hospital with an injured man, and desperately trying to get him attended. He's forced to take a number and wait, and Hilarity Ensues when it turns out the numbers are picked at random, Chapatín tears up his own right when he was about to be called, and in trying to prove his point to the doctor in charge, he only shakes the injured man around causing him even more pain.
- Candid Camera used the premise for a prank. The victim was the only one in the waiting room, but he was told to take a number and wait for it to be called. He was number 36. At first she paused between numbers, even though nobody was there to answer. As she got close to his, she started calling them out in rapid succession and eventually skipped over him. "Who's got 30? Anybody? 31... 32... 33... 34-35-36-37.... 38? Who's got 38?"
- A song by The Killers advises to "take a number where the blood's just barely dry..."
- Sesame Street:
- Naturally, the show does this with Grover and Mr. Johnson, one of the Fat Blue characters. Mr. Johnson, holding number 40, has to wait while bakery clerk Grover calls numbers 1 through 38 for non-existent clientele. Of course, at number 39, a woman shows up with an extremely long and complicated list which Grover proceeds to fill, leaving the hapless Mr. Johnson screaming in frustration.
- In an alternate ending, Grover finally reaches number 40. A relieved Mr. Johnson asks for a jelly doughnut in a bag, but Grover asks him to take another number: number 41. Then Grover starts over at number 1, causing Mr. Johnson to faint.
- In one episode, Gordon is helping Oscar do his shopping at a story run by grouches for grouches. The store owner makes him take a number, 19, then goes through all the numbers starting at 1, even though Gordon is the only one waiting. When he finally gets to 19, other customers appear with the same number on their tickets.
- In Episode 4931, Elmo, Abby, and Cookie Monster tag along with Alan when he goes shopping at Sarita's Supermarket. To make food shopping more fun for them, Alan starts a game where Elmo, Abby, and Cookie need to find three foods that start with the letter C from different sections of the grocery store before he finishes checking out. Cookie goes to the bakery to get a cookie for the game, and the baker makes him take a number. Cookie's number is 108, and Cookie worries he might not get his cookie before Alan finishes checking out, but fortunately, he does.
- Played with in the point-and-click adventure game Space Quest 6. You take a number and get 3, however the current number being served is 4, and it counts up from there of course.
- World of Warcraft: The first encounter with Nexus-Prince Haramad has him telling you that "If you are here to kill me, please take a number and wait for your turn."
- In the demo of The Stanley Parable, you take a number and wait a minute or two before you meet the Narrator (if you do wait, that is). When you get to this room again in the demo, you can wait again until your number shows up again, if only to mess with the Narrator.
- If, or rather when you are killed in Shin Megami Tensei IV, you'll be sent to the shores of the river Styx, and meet Charon, who's massively overworked, his "office" covered in paperwork and surrounded by countless dead souls. He gives you the chance to grease his palms a bit, but if you can't, or won't for some reason, he'll hand you a number... a very, very long number... and then send you to the back of the queue.
- The Heterodyne Castle in Girl Genius has a (pink) psychological torture room that include a number system... but the machine for the victims is out of numbers. Othar doesn't take it well.
- In Flare, the title character imagines burglars doing this after she reads that a house is robbed every 15 seconds.
- On Evil, Inc., when Lightning Lady goes on Saving Christmas, she has to take a number because of the huge amount of fictional characters already doing this.
- In Full Frontal Nerdity the nerds are tricked into a situation where they and a large group of other geeks are about to have their souls eaten by a demon and they're all told to take numbers and get in line to be devoured.
- Garfield and Friends: Happens to Garfield in "Mini Mall Matters", while waiting to get yogurt at a frozen yogurt store. His number is 3478; the cashier calls out for number three. Despite the fact that he is the only customer there. Becomes a Brick Joke at the end of the episode when a man who hasn't eaten in months and was marooned on an island visits the frozen yogurt store. He gets the number 2912, and the cashier calls for number six.
- Spoofed in an episode of ReBoot. Bob needs to get "slow food" from Al's Wait-And-Eat, and is told to take a number. Bob's number is "1000000000000", but since it's in binary, Bob remarks, "4096? Must be the lunch rush..." Still, Al's waiter calls out, "Now serving number 3..."
- In the South Park episode when the town loses all Internet service, Stan, his sister and his dad have to take numbers to get rationed Web access at a refugee camp. Features both versions of the trope: the fighting and the closing.
- Happens in SpongeBob SquarePants. After many issues with trying to get a bus out of Rock Bottom, SpongeBob goes to ask for a schedule. However, there's a huge line, and SpongeBob has to wait all the way in the back. The person ahead of him, uh, lays on egg on top of his head stating his number in line.  And when he actually reaches the end of the line, the clerk simply says that the next bus to Bikini Bottom leaves in five seconds, then "Sorry, we're closed" ensues.
- Wakfu episode "Miss Ugly": In the flashback showing the backstory of the Ugly Princesses, there is such a long line of princes waiting to woo them that they use a "Take a Number" device. Then comes the god Osamodas, who picks number 666 before laying a curse on the disrespectful princesses.
- In the Teen Titans Go! episode "Legendary Sandwich", Robin has to wait in the bakery department of the supermarket and gets number 78 with them serving number 22. While played for laughs, it's clearly a more realistic take on the trope.
- The stealing variant is done rather morbidly in the Dan Vs. episode "Dan Vs. the DMV": Dan is stuck with a four-digit number at the place while renewing his driver's license, so he "trades" with a man sitting next to him who has a lower number, and has apparently died waiting his turn. He struggles to take the number out of his fingers, so he rips his arm off instead. Of course, after filling out a ton of paperwork, the place closes before Dan can return it.
- In an episode of The Simpsons, Lisa tricks Homer and Bart into thinking they have leprosy and Ned sends them to a Hawaiian rehab center. While Homer is receiving a painful operation, Bart looks at his ticket, a #2.
- In one episode of Archer, Lana finds out that Cyril has been repeatedly cheating on her. In revenge, she publically announces that any ISIS employee hoping to have sex with her is welcome to show up outside Cyril's office with a number. Almost every male employee immediately converges on the office, but only Pam is smart enough to actually take a number, at least at first. After Lana refuses to have sex with Pam, they devise a scheme to charge the rest of the potential customers for the right to claim that they had sex with Lana.
- In one Megas XLR episode, Coop has to wait in line at the DMV. When the number announced was 12, Coop looked at his number to see that he has 1271.
- Played with in My Little Pony: Friendship Is Magic. When Rainbow Dash enters a flying contest, instead of taking a number, she and her competitors are issued numbers to determine the order of who goes out and does their routine for the judges. Dash is nervous and reluctant to perform and buys time by trading her low number with contestants with higher numbers.
- In the Sonic Boom episode, "Mayor Knuckles", when Dr. Eggman comes to see Knuckles, who is working as the temporary mayor, to protest about his trash not being picked up, Knuckles tells him that he has a lot of people waiting, and that he has to take a number. As Eggman points out, the machine is out of numbers. Knuckles then tells Eggman he has to fill out a complaint form, and Eggman asks him if he can get one. Knuckles simply tells Eggman to take a number. This gag happens twice again later in the episode; the first time when Eggman gains control of Knuckles' stamp and looks for the form to strip waste management of vacation time, and the second when Mayor Fink returns and Eggman asks him if he can get his trash collected.
- Real Life Turn-o-Matic slips do in fact contain three digits, but the first digit is only an outline and generally used to discourage someone from cheating the system by keeping their ticket and returning another day. For example, if your ticket reads 219, you can't return tomorrow (after the numbers have rolled over) and use that ticket to skip the line because while the number being served might be 19 again, staff will be aware the first digit has incremented.
- In more sophisticated systems, visitors select the nature of their business upon their arrival and are issued a ticket with a letter and a number (such as B-53). A computer tracks the order of arrival and the selected purpose of each visitor. When a staff member becomes available, the computer selects the next person in line and displays their number alongside the counter or station they should proceed to. Since the order is tracked by the computer rather than simply counting upwards, it is impossible for a visitor to determine when their turn will come up by looking at their number.
- As a bit of humor, one can buy a paperweight featuring a novelty hand grenade (that is to say, no explosives in it) with a number tag hanging from the pin, complete with a sign reading "Please take a number".

BHK: a proof of ∃ x : S, P(x) is a pair <a, b> where a is an element of S, and b is a proof of P(a).
The core definition is
for a type former ex that can be used to build propositions of
the form ex P, where P itself is a function from witness
values in the type A to propositions. The ex_intro
constructor then offers a way of constructing evidence for ex P,
given a witness x and a proof of P x.
The more familiar form ∃ x, P x desugars to an expression
involving ex:

Programming with Propositions
- If l is the empty list, then x cannot occur on it, so the
property "x appears in l" is simply false.
- Otherwise, l has the form x' :: l'. In this case, x occurs in l if either it is equal to x' or it occurs in l'.

- This way of defining propositions, though convenient in some cases, also has some drawbacks.
- In particular, it is subject to Coq's usual restrictions regarding the definition of recursive functions, e.g., the requirement that they be "obviously terminating."
- In the next chapter, we will see how to define propositions inductively, a different technique with its own set of strengths and limitations.
Coq vs. Set Theory
Functional Extensionality
Example function_equality_ex : plus 3 = plus (4 - 1). by []. Qed.
In common mathematical practice, two functions f and g are
considered equal if they produce the same outputs:
In mathematics, the difference doesn't matter all that much for finite objects. But in the infinite case, it's a completely different world.
For mathematical functions, an extensional definition is a set-theoretical
one: identify the function with its graph, i.e., the collection of all the
pairs related by it.
From an intensional point of view, what does it mean for two functions
defined by different equations to be the same?
Functional extensionality is not one of Coq's basic axioms: the only way to
show that two functions are equal is by simplification (as we did in the
proof of function_equality_ex). This means that some "reasonable"
propositions are not provable.
(∀x, f x = g x) → f = g
This is known as the principle of functional extensionality.
- Intensional definitions state necessary and sufficient conditions; a property, a formula like a defining equation
- An extensional definition simply enumerates all the elements that fall under its scope
Lemma plus_comm_ext : plus = fun n m ⇒ m + n.
Proof.
(* Stuck *)
Abort.
Proof.
(* Stuck *)
Abort.
But we can add it to Coq's core logic using the Axiom
command.
Module MyFunExt.
Axiom functional_extensionality : ∀{X Y: Type}
{f g : X → Y},
(∀(x:X), f x = g x) → f = g.
Axiom functional_extensionality : ∀{X Y: Type}
{f g : X → Y},
(∀(x:X), f x = g x) → f = g.
Using Axiom has the same effect as stating a theorem and
skipping its proof using Admitted, but it alerts the reader that
this isn't just something we're going to come back and fill in
later!
We can now invoke functional extensionality in proofs:

In fact, there is also a library where the corresponding axiom is hidden: Coq.Logic.FunctionalExtensionality
Require Import Logic.FunctionalExtensionality.
Print functional_extensionality.
Print functional_extensionality.
Naturally, we must be careful when adding new axioms into Coq's
logic, as they may render it inconsistent — that is, it may
become possible to prove every proposition, including False!
Unfortunately, there is no simple way of telling whether an axiom
is safe: hard work is generally required to establish the
consistency of any particular combination of axioms. Fortunately,
it is known that adding functional extensionality, in particular,
is consistent.
Note that it is possible to check whether a particular proof
relies on any additional axioms, using the Print Assumptions
command. For instance, if we run it on plus_comm_ext proved above, we see
that it uses the variant of functional extensionality from the module—-and, notably, no other axioms.
Print Assumptions MyFunExt.plus_comm_ext.

Zoltán Gombocz (18 June 1877 – 2 May 1935) was a Hungarian scholar specializing in Finno-Ugric languages, but also in Turkic languages.
Gombocz was born in Ödenburg/Sopron, and spent his early years there, where his father was a professor at an evangelical college. He studied philology, which also included Romance languages, under the linguists Josef Szinnyei, August Ph. Becker and also Zsigmund Simonyi at Budapest University, and through them absorbed the principles of the Junggrammatiker. Szinnyei's diplomacy is said to have been decisive in influencing Gombocz's decision to concentrate on languages related to Hungary's historic roots. he obtained his doctorate in 1900. He studied abroad, under the Jesuit linguist Jean-Pierre Rousselot at the Collège de France in Paris,in Germany over 1903/4 in Leipzig where he came under the influence of Hermann Paul and Wilhelm Wundt, and in Finland where he mastered Finnish.
He took up appointments successively thereafter as Professor of Finno-Ugric languages at Kolozsvár and Szeged, and was appointed chair of the subject in Budapest in 1921, where he rose to become rector in 1927 of the most prestigious institution of learning in his country, Eötvös Loránd University. Aside from writing a key modern text on Hungarian, An Outline of a Historical Hungarian Grammnar, Gombocz tackled one of the most recondite problems of his discipline the reconstruction of the ancient vowel and vowel-ablaut system of proto-Finno-Ugrian, which, together with the work of his Finnish colleague Eemil Nestor Setälä, put Finno-Ugrian phonology on a firm scientific basis. Together with his friend and colleague Melich János,Gombocz compiled a comprehensive etymological dictionary of Hungarian, the first scientific work of its kind for one of the Finno-Ugrian languages. Gombocz also mastered Turkology and made fundamental contributions to the topic, writing important papers on the analysis of Turkic loan-words into Hungarian.

Here on Hacker News two Wednesdays ago the most subscribed item on the DemandRush ShowHN was 'Industry-specific deep learning interviews and walkthroughs'.
Deep learning is having a major impact across every major industry, but for a software engineer, the only real tutorials you see are for generic use-cases - eg train imagenet, etc - nothing industry specific.
I wish there was a way to learn how deep learning is used in specific industries like autonomous vehicles, drug discovery, energy, drones, medical imaging. And besides just learning the use-case, I want to be able to follow step-by-step tutorials showing what the work actually looks like.
Example - "DeepChem founders interviewed this week. Here's a tutorial where you learn about the steps of drug discovery, and build a model to identify..."
Enterprise Deep Learning™ is a monthly newsletter made specifically for you. In each newsletter a deep learning expert is interviewed, and a industry-specific tutorial is published.
If the pilot is successful, you will be able to subscribe to monthly Enterprise Deep Learning newsletters for $10/month. This pilot month, June, is free.
The pilot will be released to email subscribers June 30th some day I have time.
Here on Hacker News two Thursdays ago is an example of a company bringing deep learning to market that we would welcome have invited have interviewed for a pilot episode.
I would like to have more companies like this work with me with the mutually beneficial caveat, particularly for the company, that all of the information shared between us, including my code implementation - based upon their guidance - and their audio walkthrough of their product, be released to the company for use anywhere they want beyond the newsletter. Email me.
Get the pilot newsletter as soon as it's completed.

Automated unit testing is a great way to ensure that code being maintained works and continues to work. The Extreme Programming (XP) methodology relies heavily on it, and practitioners have available to them a range of unit testing frameworks, which work by making direct calls to the code being tested. But what if you want to test a web application? HttpUnit is a library which makes this possible.
HttpUnit works by emulating a browser, handling frames, cookies, redirects, and so on. It lets you view pages as plain text, an XML DOM, or as an aggregation of collection of links, frames, images, and so on. It lets you select an element which should lead to a new page and follow it, so that you can easily handle a chain of web pages.
Unlike most commercial tools, HttpUnit does not rely on record and playback. Its API lets you define what you want to see or change, even before the web site is built. This is essential for test-first development. Since the primary use of HttpUnit is to write functional tests, it helps you abstract those elements which are most likely to change. For example, a page might start by providing a small number of options, using a set of radio buttons:
As the site evolves, the number of options might grow until the UI designer feels that a pull-down menu would be easier to use to send the same values:
Further expansion could lead to a free-form textual input:
A tool which focuses on the type of control actually on the page would force the testers to rewrite their tests with each change, even though the functionality of the site is unchanged. HttpUnit focuses on the intent of the entry, and allows tests to be defined in terms of the values to be transmitted. It is aware of the controls being used and ensures that only values which a user could supply will be sent; however, the tester need only focus on the desired value for each test.

Weather advisory issued for south with gales and heavy rain forecast
Remnants of Atlantic storm passes on Tuesday with Wexford, Cork and Waterford to be hit
Met Éireann has issued a weather advisory for Wexford, Cork and Waterford on Tuesday as the remnants of an Atlantic storm passes along the south coast of Ireland.
A combination of high tides, strong winds and heavy bursts of rain will impact the south coast, bringing a risk of flooding during Tuesday.
More generally, strong to gale force easterly winds and heavy rain are forecast for much of Munster and Leinster tomorrow.
Met Éireann said the powerful winds were coming from weather system in the mid-Atlantic which is moving towards Ireland.
While the winds will be powerful they have not prompted a weather warning.
For the rest of the week the weather is set to remain unsettled, cloudy and showery until Friday when dry, sunny spells should develop and continue into the weekend.
The cloudy conditions for the early part of the week will see daytime temperatures around normal for this time of year, in the region of 9 degrees to 12 degrees, with mostly frost free nights.
On Thursday night temperatures will fall to between minus 2 to 3 degrees overnight with a risk of frost.
Temperatures will remain lower on Friday and into the weekend.

ClickHouse Roadmap is publicly available on GitHub:
https://github.com/ClickHouse/ClickHouse/issues/17623
I will show you only some highlights and examples.
Provide alternative for ZooKeeper Nested and semistructured data Limited support for transactions Backups Hedged requests Window functions Separation of storage and compute Short-circuit evaluation Projections Lightweight DELETE/UPDATE Workload management User Defined Functions Simplify replication JOIN improvements Embedded documentation Pluggable auth with tokens
Work in progress. Initial support in version 21.1.
Data types:
Tuple(T1, T2...)
Tuple(x1 T1, x2 T2...)
Map(T1, T2)
Nested(x1 T1, x2 T2...)
Support for subcolumns:
SELECT cart.id, cart.price FROM table
— only queried subcolumns will be read from table.
Work in progress. Initial support in version 21.1.
Multiple nesting:
cart Nested( item_id UInt64, item_price Decimal(20, 5), features Nested( ...))
SELECT cart.item_id, cart.features.f1 FROM table
SELECT cart.* FROM table
Maps naturally to nested JSON and Protobuf.
Work in progress. Initial support in version 21.1.
SET allow_experimental_window_functions = 1
Already supported:
— OVER (PARTITION BY ... ORDER BY ...)
— aggregate functions over windows;
— WINDOW clause;
Upcoming:
— non-aggregate window functions (rank, etc...);
— frame specifications;
Multiple data representations inside a single table.
— different data order;
— subset of columns;
— subset of rows;
— aggregation.
Work in progress.
Difference to materialized views:
— projections data is always consistent;
— updated atomically with the table;
— replicated in the same way as the table;
— projection can be automatically used for SELECT query.
Work in Progress.
— ZooKeeper network protocol is implemented;
— Abstraction layer over ZooKeeper is used;
— ZooKeeper data model is implemented for testing;
— TestKeeperServer: a server with ZooKeeper data model for testing;
Benefits:
— less operational complexity;
— fix "zxid overflow" issue;
— fix the issue with max packet size;
— fix "session expired" due to gc pauses;
— improve memory usage;
— allow compressed snapshots;
— allow embedding into clickhouse-server.
SELECT IF(number = 0, 0, 123 % number) FROM numbers(10)
— division by zero.
SELECT * FROM numbers(10) WHERE number > 0 AND 10 % number > 0
— division by zero.
— both branches of IF, AND, OR are always evaluated.
SELECT * FROM ( SELECT * FROM numbers(10) WHERE number > 0 ) WHERE 10 % number > 0
— division by zero.
We are considering five ways to implement UDF, two of them are mandatory:
1. UDF as SQL expressions.
CREATE FUNCTION f AS x -> x + 1
2. UDF as executable script.
Interaction via pipes, data is serialized using supported formats.
Send distributed query to multiple replicas — to mitigate tail latencies.
This is needed for distributed queries on large clusters (with large "fanout").
Work in progress.
* The largest ClickHouse cluster in Yandex is 630+ servers,
but there are many larger clusters in other companies.
Native integration with PostgreSQL
— PostgreSQL table engine and table function;
— PostgreSQL dictionary source;
— PostgreSQL database engine as a view to all tables in PG database;
Available in version 21.2-testing.
In previous versions it was only available via ODBC with many complications.

Hello, my name is Amrit. I am creator & author of spanit.xyz. I began programming at the age of 17. The first program I wrote was a "Number Addition" app using NetBeans Java SDK, this event made me realise the true potential of computer programming, hence I made the clarion call to learn software development.
In college I learned C language, which I never used other than solving algo-related problems. In 2015 I genuinely become a fan of Python and its much simpler syntax structure, so I taught myself basics of Python. In 2017 I taught myself Web Development.
To sum up, I have gained experiences in following pieces of technology: Website Development(HTML, CSS/SASS, JS, PWAs), Bot Development(NodeJS), QA Testing(Selenium WebDriver), C, Python, AngularJS and Git
Apart from Software Development and Design, I am studying Civil Engineering in college. Also, I have keen interest in Social Media Advertising and Marketing and Setting up Teams and Organisation. In 2017 I, with other fellow developers, formed an online community to help, discuss, share, work and collaborate together on freelance and open-source projects, its called VividCiphers.

I am looking forward to joining the DBC experience (or maybe I should say experiment?)! The idea that Dev Bootcamp is a kitchen, rater than a restaurant, is very appealing to me. For anyone who is confused by what I mean here: a Kitchen mindset is where everyone is a cook in the kitchen. Some people might be a little more experienced than others, but it is going to take every one of them in order to create a final meal. In this way, Dev Bootcamp is an environment where each person is a part of a group and it will take every member in order to create the final experience. On the flip side, a Restaurant mindset is set up where you are the consumer. You paid for this experience, you are entitled to a certain experience, the end. This reminds me, somewhat, of a growth vs fixed mindset.
I am very excited to join an environment like this. The idea that so much of the learning can come from the people around you. I have found that you can learn information out of a book, but it is you peers that are your best teachers. They will show you all of the little tricks and tips that will enhance the whole experience. I am also looking forward to joining a whole group of people who are at my level and growing alongside them. I'm definitely nervous about the whole experience, but with those nerves comes the sense of adventure. It will be so rewarding to reflect at the end of the process to see how far we have all come!
I am also looking forward to pair programming. I love working closely with other people in order to achieve a common goal. I am also looking forward to the challenge of working with a variety of different people who all have different abilities, communication strengths and styles. Being able to effectively work with just about anyone you come across is such an important skill. This is one of the things I love about the DBC philosophy; that so much of your transformation is going to come from relationships with the people around you.
Shereef's Fireside Chat also managed to aleviate some fears that I had. I was very nervous that some people were going to come in and be so far ahead that I wouldn't be able to catch up. Shereef changed my perspective a little, in that there is so much out there to learn so those people who seem far ahead are only a few steps up in the grand scheme of things. His analogy of walking from San Fransisco to New York, where some people have taken 100 steps and others have only taken 5, helped to take down myanxiety level.
I'm also very interested in time boxing. This is something I feel like I used to do but have fallen out of habit. When I was in high school, I would only allow myself to work on schoolwork until a certain time at night. Whatever I didn't finish would have to wait because I was not going to drive myself crazy by staying up all night. In my Phase 0 work this week, I've tried to time box based on the average times for each challenge, and I think it is helping me to stay on track.

Entity Relation mapping
Relationships among entities may be one-to-one, one-to-many, many-to-one, or many-to-many.
Relationships may be bidirectional or unidirectional. A bidirectional relationship has both an owning
side and an inverse (non-owning) side. A unidirectional relationship has only an owning side.
Jeddict supports the following association mapping types for Java persistent entities:
Unidirectional relationship
Unidirectional One-to-one mapping :
Use a One-to-One Mapping to define a relationship with one-to-many multiplicity.
Following example shows a one-to-one relationship between Employee and TravelProfile. Employee is the
“one” side and the source of the relationship, and TravelProfile is also the “one” side and the target.
Because the arrow points in only one direction, from Employee to TravelProfile, the relationship is unidirectional.
In this example:
- Entity Employee references a single instance of Entity TravelProfile.
- Entity TravelProfile does not reference Entity Employee.
- Entity Employee is the owner of the relationship.
The following mapping defaults apply:
- Entity Employee is mapped to a table named EMPLOYEE.
- Entity TravelProfile is mapped to a table named TRAVELPROFILE.
- Table EMPLOYEE contains a foreign key to table TRAVELPROFILE. The foreign key column is named PROFILE_ID.
The foreign key column has the same type as the primary key of TRAVELPROFILE, and there is a unique key constraint on it.
Unidirectional One-to-many mapping :
Use a One-to-Many Mapping to define a relationship with one-to-many multiplicity.
When an entity is associated with a Collection of other entities, it is most often in the form of a one-to-
many mapping.
In this example:
- Entity Employee references a collection of Entity AnnualReview.
- Entity AnnualReview does not reference Entity Employee.
- Entity Employee is the owner of the relationship.
The following mapping defaults apply:
- Entity Employee is mapped to a table named EMPLOYEE.
- Entity AnnualReview is mapped to a table named ANNUALREVIEW.
- There is a join table that is named EMPLOYEE_ANNUALREVIEW (owner name first). This
join table has two foreign key columns. One foreign key column refers to table EMPLOYEE and has the same type as the primary key of EMPLOYEE. This foreign key column is named
EMPLOYEE_ID. The other foreign key column refers to table ANNUALREVIEW and
has the same type as the primary key of ANNUALREVIEW. This foreign key
column is named ANNUALREVIEWS_ID. There is a unique key constraint on the foreign key that refers to table ANNUALREVIEW.
Unidirectional Many-to-one mapping :
Use a Many-to-One mapping to defines a single-valued association to another entity class that has many-to-one multiplicity.
Following example shows a many-to-one relationship between Phone and Employee. Phone is the
“many” side and the source of the relationship, and Employee is the “one” side and the target. Once
again, because the arrow points in only one direction, from Phone to Employee, the relationship is
unidirectional.
In this example:
- Entity Employee references a single instance of Entity Phone.
- Entity Phone does not reference Entity Employee.
- Entity Phone is the owner of the relationship.
The following mapping defaults apply:
- Entity Employee is mapped to a table named EMPLOYEE.
- Entity Phone is mapped to a table named PHONE.
- Table PHONE contains a foreign key to table EMPLOYEE. The foreign key column is named OWNER_ID.
The foreign key column has the same type as the primary key of EMPLOYEE.
Unidirectional Many-to-many mapping :
Use a Many-to-Many Mapping to define a many-valued association with
many-to-many multiplicity. A many-to-many mapping has two sides: the owning side
and non-owning side. You must specify the join table on the owning side. For
bidirectional mappings, either side may be the owning side.
In this example:
- Entity Employee references a collection of Entity Patent.
- Entity Patent does not reference Entity Employee.
- Entity Employee is the owner of the relationship.
The following mapping defaults apply:
- Entity Employee is mapped to a table named EMPLOYEE.
- Entity Patent is mapped to a table named PATENT.
- There is a join table that is named EMPLOYEE_PATENT (owner name first). This join table
has two foreign key columns. One foreign key column refers to table EMPLOYEE and has the
same type as the primary key of EMPLOYEE. This foreign key column is named
EMPLOYEE_ID. The other foreign key column refers to table
PATENT and has the same type as the primary key of PATENT. This foreign key column is
named PATENTS_ID.
Bidirectional relationship
Bidirectional One-to-one mapping :
Use a One-to-One Mapping to define a relationship with one-to-many multiplicity.
In this example:
- Entity Employee references a single instance of Entity Cubicle.
- Entity Cubicle references a single instance of Entity Employee.
- Entity Employee is the owner of the relationship.
The following mapping defaults apply:
- Entity Employee is mapped to a table named EMPLOYEE.
- Entity Cubicle is mapped to a table named CUBICLE.
- Table EMPLOYEE contains a foreign key to table CUBICLE. The foreign key column is named
ASSIGNEDCUBICLE_ID. There is a unique key constraint on foreign key.
Bidirectional Many-to-one mapping :
Use a Many-to-One mapping to defines a single-valued association to another entity class that has many-to-one multiplicity.
In this example:
- Entity Employee references a single instance of Entity Department.
- Entity Department references a collection of Entity Employee.
- Entity Employee is the owner of the relationship.
The following mapping defaults apply:
- Entity Employee is mapped to a table named EMPLOYEE.
- Entity Department is mapped to a table named DEPARTMENT.
- Table EMPLOYEE contains a foreign key to table DEPARTMENT. The foreign key column is named DEPARTMENT_ID.
Bidirectional Many-to-many mapping :
Use a Many-to-Many Mapping to define a many-valued association with
many-to-many multiplicity. A many-to-many mapping has two sides: the owning side
and non-owning side. You must specify the join table on the owning side. For
bidirectional mappings, either side may be the owning side.
In this example:
- Entity Project references a collection of Entity Employee.
- Entity Employee references a collection of Entity Project.
- Entity Project is the owner of the relationship.
The following mapping defaults apply:
- Entity Project is mapped to a table named PROJECT.
- Entity Employee is mapped to a table named EMPLOYEE.
- There is a join table that is named PROJECT_EMPLOYEE (owner name first). This join table
has two foreign key columns. One foreign key column refers to table PROJECT and has the
same type as the primary key of PROJECT. The name of this foreign key column is
PROJECTS_ID. The other foreign key column refers to table EMPLOYEE and
has the same type as the primary key of EMPLOYEE. The name of this foreign key column is
EMPLOYEES_ID.

Following the record type is the scope information for the symbol. 'G' indicates Global . F<filename> indicates the symbol is active for a given file only (e.g. global variables declared as 'static') L<functionName> indicates that the symbol is local to the function with the given name. The follows the name of the variable (this is the unmangled/user given name of the variable). The level & block are used to further scope local variables since C allows the definitions like ...
foo()
{
int c; /* block #1 , level #1 */
{
int c; /* block #2, level
#2 */
...
}
{
int c; /* block #3 , level
#2 */
...
}
}
The type info is a chain of type (since C allows declarations of arbitrary complexity. The type info has the following format .
({size}<type info chain>)
size - size in bytes of the symbol.
<type info chain> - should be parsed into a linked list of
type, the elements of the list are described below.
| Type Code | Description |
| DA<n> | Array of n elements |
| DF | Function |
| DG | Generic pointer |
| DC | Code pointer |
| DX | Xternal Ram pointer |
| DD | Internal ram pointer |
| DP | Paged pointer |
| DI | Upper 128 byte pointer |
| SL | long |
| SI | int |
| SC | char |
| SS | short |
| SV | void |
| SF | float |

Declaration.
idata char BCD_Cell[5];
Generates the following debug info.
S:G$BCD_cell$0$0({5}DA5,SC:S),G,0,0
The following function declaration along with local variables and parameters.
void uitoa(unsigned int value, char* string, int radix)
{
char buffer[NUMBER_OF_DIGITS];
..
}
Will generate the following debug information.
/* function "uitoa" */
F:G$uitoa$0$0({2}DF,SV:S),C,0,0
/* parameter "value" */
S:Luitoa$value$1$1({2}SI:S),E,0,0
/* parameter "string" */
S:Luitoa$string$1$1({3}DG,SC:S),E,0,0
/* parameter "radix" */
S:Luitoa$radix$1$1({2}SI:S),E,0,0
/* local variable "buffer" */
S:Luitoa$buffer$1$1({16}DA16,SC:S),E,0,0
Details of 'T'-Type (Structure Record)
--------------------------------------
Structure definitions ALWAYS have file scope. Currently structure definitions
within functions or blocks are not handled in the debug information.
Structure
and unions are represented using the same debug format. The format
of the
Structure record is as follows .
T:F<filename>$tag[({offset}<Symbol Record 'S' type for 1st field>)
({offset}<Symbol Record 'S' type for 2nd field>)
...
...
]
Example 1.
----------
Definition
struct some_struct {
int a;
char b;
long c;
};
Generates the following 'T' - type record.
T:Fprob38$some_struct[
/* field 'a' offset = 0 */
({0}S:S$a$1$0({2}SI:S),Z,0,0)
/* field 'b' offset = 2 */
({2}S:S$b$1$0({1}SC:S),Z,0,0)
/* field 'c' offset = 3 */
({3}S:S$c$1$0({4}SL:S),Z,0,0)]
The 'S' - type (symbol rescord for each of the fields is embedded inside
the structure definition record.
Example 2.
----------
Structure declarations with embeded structures.
union bil {
struct {
volatile unsigned char b0,
b1,
b2,
b3 ;
} b;
struct {
volatile unsigned int lo,hi ;
} i;
unsigned volatile long l;
struct {
volatile unsigned char b0;
unsigned int i12;
unsigned char b3;}
bi;
} ;
Generates the following debug information. NOTE: the embedded anonymous
structures generates separate T - type records.
T:Fprob38$bil[
/* field 'b' is of type Structure __00020000 , offset = 0 */
({0}S:S$b$1$0({4}ST__00020000:S),Z,0,0)
/* field 'i' is of type structre __00020001 , offset = 0 (union) */
({0}S:S$i$1$0({4}ST__00020001:S),Z,0,0)
/* field 'l' is of type unsigned long */
({0}S:S$l$1$0({4}SL:U),Z,0,0)
/* field 'bi' is of type structure __00020002 offset = 0 */
({0}S:S$bi$1$0({4}ST__00020002:S),Z,0,0)]
/* compiler generates these 'T'-type records for the
anonymous structures */
/* T record for structure __00020000 (field 'b' in the above structure) */
T:Fprob38$__00020000[
/* field 'b0' type unsigned char , offset = 0 */
({0}S:S$b0$2$0({1}SC:U),Z,0,0)
/* field 'b1' type unsigned char , offset = 1 */
({1}S:S$b1$2$0({1}SC:U),Z,0,0)
/* field 'b2' type unsigned char, offset = 2 */
({2}S:S$b2$2$0({1}SC:U),Z,0,0)
/* field 'b3' type unsigned char , offset = 3 */
({3}S:S$b3$2$0({1}SC:U),Z,0,0)]
/* T record for structure __00020001 (field 'i' in union 'bil' ) */
T:Fprob38$__00020001[
/* field 'lo' type unsigned int offset 0 */
({0}S:S$lo$2$0({2}SI:U),Z,0,0)
/* field 'hi' type unsigned int offset 2 */
({2}S:S$hi$2$0({2}SI:U),Z,0,0)]
/* T record for structure __00020002 (field 'bi' in union 'bil' )*/
T:Fprob38$__00020002[
/* field 'b0' type unsigned char , offset 0 */
({0}S:S$b0$2$0({1}SC:U),Z,0,0)
/* field 'i1' type unsigned int , offset 1 */
({1}S:S$i12$2$0({2}SI:U),Z,0,0)
/* field 'b3' type unsigned char offset 3 */
({3}S:S$b3$2$0({1}SC:U),Z,0,0)]
Details of 'F'-Type (FUNCTION Record)
--------------------------------------
A Function record is created for each function defined in the C Source
file. The format of a function record is identical to that of the Symbol
record. The function record contains information about the return value
of a function, in addition it contains information about the register
bank
the function uses and if the function is an interrupt service routine
the
interrupt number of the function.

All Saints Anglican Church
A journey to discover and deepen your spirituality.
Create an opportunity to relax, have fun, be creative and reconnect with yourself and your family.
Messy Church is a new concept in South Africa and is tailored especially for families (both parents and children) who feel the stresses and pressures of living in Johannesburg. It is an exciting new once-monthly programme at All Saints Church, Fourways Gardens - to reach out to families and to provide an opportunity for conversation and community building – through crafts and activities, worship and a shared meal. It recognizes that our spiritual journey is indeed messy. We acknowledge that the formal Sunday services may be too inconvenient and formal for many people. So, we aim to provide fun and creative activities, and opportunities for fellowship and learning – where it is easy to invite a friend to join in the fun and receive God’s love, and so we can minister to a wider circle than the regular church-goers.
“Messy Church gets the message of God across in a fun and engaging way for the children ie it removes a bit of the “boring perception” of the Church. Messy Church also allows children and families to get together and form friendships and bonds with people from diverse cultures within the Church. ” Anne, mother of Devin (age 5)
We meet on the second Sunday of every month, from 3 – 5pm. You are welcome to come with your family and deepen your spirituality as you embark on your messy trail.


This task will guide you through the process of debugging a Windows Desktop Bridge App using Visual Studio 2017.
Basic knowledge of C# development
Basic knowledge of client development with the .NET framework
Basic knowledge of Windows 10 and the Universal Windows Platform
A computer with Windows 10 Anniversary Update or Windows 10 Creators Update. If you want to use the Desktop App Converter with an installer, you will need at least a Pro or Enterprise version, since it leverages a feature called Containers which is not available in the Home version.
Visual Studio 2017 with the tools to develop applications for the Universal Windows Platform. Any edition is supported, including the free Visual Studio 2017 Community
The Desktop Bridge Debugging Project template installed into Visual Studio 2017
Complete the section on Add Desktop Bridge Support using Visual Studio 2017
To get started, please open the Microsoft.Knowzy.WPF.sln in the src\Knowzy_Engineering_Win32App folder with Visual Studio 2017.
This task covers the following steps: 1. Install the Desktop Bridge Debugging Project Extension
Add a Desktop Bridge Debugging project and add project dependencies to the existing WPF and UWP projects
Configure the Debugging Project to enable F5 builds and deployment of the Knowzy app
Enable breakpoints in projects
If you do not have the Desktop Bridge Debugging Project extension installed into Visual Studio 2017, please complete the following steps:
Click on the Tools menu and select Extensions and Updates...
Select Online and enter Desktop Bridge Debugging Project in the search field. Click Download.
Close Visual Studio 2017 and the Desktop Bridge Debugging Project Extension will be installed.
Reopen your Desktop Bridge solution from the Add Centennial Support using Visual Studio 2017 task.
Right-click on the src folder in the Solution and select Add | New Project...
Select the Other Project Types | Desktop Bridge Debugging Project project template.
Name the project Microsoft.Knowzy.Debug.
Make sure you save the project to the Knowzy_Engineering_Win32App\src folder.
You solution should now contain the following projects.
Right-click on the Microsoft.Knowzy.Debug project and select Build Dependencies | Project Dependencies..."
Select the Microsoft.Knowzy.WPF and Microsoft.Knowzy.UWP projects and click OK.
Since we will be working a lot with the Microsoft.Knowzy.UWP project, set the Build Configuration and Platform to Debug | x86
Clean the solution by selecting Clean Solution from the Build menu.
Build the x86 configuration of the solution. (Select Build Solution from the Build menu).
After the build completes, deploy the Microsoft.Knowzy.UWP project so its AppX folder is created. The next step needs the AppX folder. (Select Deploy Solution from the Build menu).
Right-click on the Microsoft.Knowzy.Debug project and select Set as Startup Project.
Right-click on the Microsoft.Knowzy.Debug project and select Properties.
For Debug builds use the following settings:
Package Layout: ..\Microsoft.Knowzy.UWP\bin\x86\Release
Select Uninstall and then re-install my package.
From the Package Layout field tab to the Start Up Tile field and select Microsoft.Knowzy.WPF.
Notice that we are specifying the path to the Release build of the Microsoft.Knowzy.UWP project. This is a fix for the Visual 2017 C# UWP Desktop Bridge deployment bug we experienced in the previous task.
Save and Close the Properties windows.
Note: The Properties window can be a little buggy in saving your settings so make sure they were saved. Most issues with debugging are caused by incorrect Debugging Project settings.
Note: You will need to add the correct Debugging Project Properties for x86 Release and x64 Debug and Release configurations if you want to build them.
Open the AppXPackageFileList.xml file in the Microsoft.Knowzy.Debug project
Modify the xml to the following:
<?xml version="1.0" encoding="utf-8"?>
<Project ToolsVersion="14.0"
xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
<PropertyGroup>
<MyProjectOutputPath>..\..\bin\Debug</MyProjectOutputPath>
</PropertyGroup>
<ItemGroup>
<LayoutFile Include="$(MyProjectOutputPath)\Microsoft.Knowzy.WPF.exe">
<PackagePath>$(PackageLayout)\desktop\Microsoft.Knowzy.WPF.exe</PackagePath>
</LayoutFile>
</ItemGroup>
</Project>
This XML describes to the DesktopBridge Debugging project the location of the Microsoft.Knowzy.WPF.exe after it is built. It will use it when the project is launched and copy it to the correct location in the AppX package. This will allow for any changes to the Microsoft.Knowzy.WPF project code to be included in the debugging session. The need for the Desktop Bridge Debugging project will most likely change in future updates to Visual Studio 2017.
Save your changes.
Now it is time to Clean the solution and then Build the Solution.
If you get a Build error stating the layout file could not be found you may need to manually deploy the Microsoft.Knowzy.UWP project by right-clicking on the Microsoft.Knowzy.UWP project and selecting Deploy. Then build the solution again.
Press F5 and your UWP app will now be deployed and launch successfully. You should now be able to set breakpoints in the Microsoft.Knowzy.WPF source code.
Note: There is a intermitent bug in the Desktop Bridge Debugging Project ** where it may hang when deploying a build. If this happens, use the Task Manager to kill Visual Studio and then reopen then solution. You should then be able to build and run the app.
Set a breakpoint at line 79 in the file ViewModels\MainViewModel.cs in the Microsoft.Knowzy.WPF project. Restart the debugging session and it should break into the debugger at line 79. If you do not hit the breakpoint, Clean and Build your solution again.
Stop debugging and remove the comments we added in the previous task. Press F5 to start the app. You should get the following exception:
For some reason, our UWP app is unable to load the Project.json file and it appears that our app is looking for the file in the wrong directory. This is a common problem with newly converted Desktop Bridge apps. Depending on how the code is written, the app may be trying to load files from the wrong location. We will fix this in the next task.
Step 4: Additional Debugging Settings
In order to be able to easily debug both both the WPF and UWP portions of our app, we need to specify a few more debugging settings.
Select Options... from the Debug menu.
Click on Debugging | General and turn off the Enable Just My Code options
Right-click on the Microsoft.Knowzy.UWP project and select Properties.
Select the Build tab and turn off Optimize Code
Select the Debug tab and turn on Do not launch, but debug my code when it starts
We will now fix the products.json issue in the next task.

The thesis is often thought of to be the most important component to any writing piece. While I personally don’t believe in “formulas” when it comes to subjective competitions such as National History Day, I do believe that the template below serves as a great structure for crafting a strong thesis:
What was going on during the time of the event/person’s life you are researching? What are the barriers people in that time period had to face? What were barriers like at local, national, and global levels?
What did your person accomplish despite these barriers? What event occurred in the midst of such obstacles? Be as explicit as possible here. It may be helpful to even include time frames, spelled out words for abbreviations, etc.
By accomplishing such a feat, what barriers did the person you are researching break? What obstacles did the event overcome? You can be more general here, but you want to make sure that you touch on all of the barriers you enumerate upon somewhere in your project.
What is the significance of the person of interest breaking such a barrier? What are the modern implications for different demographics (men, women, children, people of color, etc.)? What are the ramifications for people locally, nationally, and globally? This part, in some ways, is both the easiest and the hardest aspect to write.
Of course, this is simply a template. While it would make sense for each part to follow one right after the other, it’s all about how the thesis reads. Below is an example of the thesis my partner and I wrote 3 years ago for our 7th place winning project. The theme is “Taking a Stand in History”:
Written on December 2nd , 2019 by Chris Pondoc“The need for domestic uranium saw rapid growth from the 1940’s through the 80’s, resulting in widespread mining throughout the uranium-rich Navajo Reservation, located in the southwestern United States. However, government-operated mining companies, that enlisted the help of Navajo workers, did not properly inform them of the dangers associated with uranium, nor take precautions to diminish the possible effects. As a result, Navajos were unable to object to the mining, as they did not know there was a stand to be taken. The government’s refusal to recognize the basic rights of the Navajo nation has led to long-lasting adverse health and environmental effects, still afflicting the Tribe and their land.”

Switch-In items called on login?

Are the apps in my Switch-In folder called when I log in?
-
Greg Hurrell
They're called whenever the system sends a NSWorkspaceSessionDidBecomeActiveNotification. The Cocoa docs say, "Posted after a user session is switched in. This allows an application to re-enable some processing when a switched out session gets switched back in, for example."
You could find out whether the items in that folder are called when logging in by testing it out. From memory, I don't recall whether they are or not.

The ocean is divided into zones vertically based on how far from the surface they are. Each zone has its own unique properties and wildlife—let's learn about the zones of the ocean!
The ocean is divided into zones vertically based on how far from the surface they are. Each zone has its own unique properties and wildlife—let's learn about the zones of the ocean!
The epipelagic zone, also known as the "sunlight zone" of the ocean, spans from the ocean's surface to 200m below it. At this stage, sunlight can still penetrate the water, and thus most creatures and photosynthesizing aquatic plant life lives here.
The mesopelagic zone of the ocean spans from 200-1000m below the ocean's surface. Here, sunlight is scarce, and many creatures that live here have adapted to the darkness with special features such as low light vision and bioluminescence.
The bathypelagic zone of the ocean spans from 1000-4000m below the ocean's surface. Sunlight doesn't penetrate here at all, and thus many creatures here live in total darkness. Some of them have even adapted to this environment in more radical ways, such as not having any eyes.

Build Log: Dining Table
The dining room was the only room in our new house for which we did not already have furniture, so I decided to build a dining table from scratch. We were not rushed so I was able to take my time to build a simple—but beautiful—table for our family.
Design
I have built a couple of coffee tables from 2x4's and 4x4's, but this was my first attempt at a "nice" piece of furniture. As usual my design process consisted of looking at photos online, observing tables I came across for a few months, watching some YouTube videos, and then drawing some ideas out in SketchUp.
The table is phase 1, with phase 2 being some built in benches we can add at a later time.

I purchased some ambrosia maple from the local Woodcraft store. This wood was on the cheaper end of what was available, and I really liked the grain pattern. Since I don't have a jointer or planer, I was glad to hear that they could plane the boards to the same thickness (about 1 1/2") and joint one edge.
The table finished length is 6'6" so I first cut the boards down to about 6'9", leaving a couple of inches to trim off after gluing them together.
Next I squared up the unfinished edge of each board. Ideally I would have done this on the table saw, but I lacked a suitable table saw and helper and was concerned I would leave unnecessary gouges. I opted to use my circular saw with a Bora clamp after carefully measuring with a combination square to ensure a parallel edge. The result was less than perfect due to my cheap circular saw, but I compensated for any out-of-square edges by cutting on opposite faces to cancel any error.
Next it was time to cut 5 biscuit slots per joint on all the boards and glue them up one at a time. Biscuit joinery is clean, straightforward, and strong, and I am glad I invested in a biscuit joiner earlier this year.
I glued up one joint at a time over the course of a few days. It is important to have enough large clamps for this type of project, and I bought a few more on Craigslist.
Using biscuit joints and clamped calls I was able get the boards aligned pretty well, but there were some areas of misalignment of about 1/16". I cleaned these up with the hand plane and then got to work sanding. I got a 5" random orbit sander for this project and it is a very helpful and necessary tool for producing a nice finish. I started with 60 grid sandpaper to get a smooth finish and then followed that with 120 and 220.
I wanted nice round edges so I used a router with a round-over bit on all edges, top and bottom. This is something I might not do again since it is easy enough to round over when sanding for a small radius.
The ambrosia maple has lots of small beetle holes throughout. I filled these with epoxy and then sanded them down.
After reading about a number of options, I chose do finish the table with wipe-on poly for its ease and protection. I did a total of about 5 coats over several days, and smoothed out any roughness with clean cardboard between coats. The finish really brings out the beauty of the wood!
I wanted simple legs and decided on two rectangles made from 4x4's after a few design iterations.
I cut the pieces to rough length and then trimmed them down from 3.5" x 3.5" to 2.5" x 3" on the table saw. This cleaned up the rough edges and gave a sharp looking set of legs. I joined these with biscuits as well, and painted white.
A simple 1x4 joins the legs together and provides some additional rigidity for the table. I cut slots in the 1x4s and legs for brackets to mount the tabletop, and drilled pocket hole screws in the 1x4s. I wanted to use screws for the final assembly so the table can be disassembled if ever needed.
I bought some brackets to attached the table to the legs. My reading indicates that this mounting style (rather than directly screwing the legs to the table) allows the wood to expand and contract through the seasons and lessens the risk of it cracking.

Plinth is an open source modular synthesis system that runs in your web browser. It currently consists of a demo page that lets you load and patch a set of sample modules (aka blocks), and a draft spec of a module API.
If you have have any feedback or want to contribute to the project, open an issue on GitHub or drop me a line. My name is Russ Simmons, and my email is in the format<EMAIL_ADDRESS>Each block has ports that let them connect to other blocks. Switch to the back view of the rack (using the Flip button or space bar) and you can see the ports of each block. There are two types of ports: input and output. Input ports are on the left side, and output ports are on the right.
There are two ways to wire a connection between two ports. You can either click on the first port, then click on the second port, or you can click on the first port, drag to the second port, and release. To delete a wire, first toggle Delete Wires mode via the button or the D key. In Delete Wires mode, any wire that you click on will be deleted.
There are currently two different types of signals that wires can carry: audio and gate. Each block port is of a specific type, and only ports of the same type can be connected together. Audio signals can carry either "listenable" audio or audio-rate control signals (ala control voltages). Gate signals are either "on" or "off" at any given moment in time, and are typically used as the output of clocks and the input of sequencers or envelope generators. Note: Audio signals should be able to carry gate-type signals, but there are currently technical issues that make this inconvenient. When browsers support the upcoming Audio Worklets specification, we can get rid of gate signals and only have audio signals.
A single output port can be connected to multiple inputs, in which case the same output signal is broadcast to all the inputs. Multiple output ports can also be connected to a single input. If the ports are audio-type, the signals will be summed together at the input. (If the ports are gate-type, the results are currently undefined.)
Connecting blocks in a "feedback loop" will work only in certain circumstances. For audio signals, a short delay is required somewhere in the signal path, otherwise the looping connections will be ignored. With gate signals, it is possible to cause the system to freeze in an "infinite loop", so be careful.
The rack has a special block called Rack Outputs that is used to output a final audio signal for listening. This block cannot be deleted.
