This is a visualization of a Twitter network. Each circle represents a Twitter user (that is, a unique Twitter account). The color of the user circle represents how many followers the user has from blue (fewest) to red (most). The radius of the user circle also represents how many followers the user has from small radius (fewest) to large radius (most). The x-axis shows the number of Retweets of a user within the Twitter network (that is, the number of times the user was Retweeted by users in this specific Twitter network). The y-axis shows the number of unique Retweeters within the Twitter network (that is, the number of unique users in this specific Twitter network that Retweeted a user). If you hover a user circle, the user screen name (as specified in the data) will appear by the user circle and the user circle you're hovering will become enlarged. If you click on a user circle, the up-to-date user timeline will appear. You can click on the user timeline to be redirected to Twitter's web site and view the user.

I will finish my Physics PhD from the University of Texas at San Antonio in May 2017. My research is a multi-messenger population study of gamma-ray bursts and gravitional waves. It required the development of statistical models, parameter estimation, data analysis of large data sets, and the numerical implmentation of algorithms in parallel programs that were run on the Lonestar supercomputer.
Parameter estimation is a critically important subject with real-world applications. We often want to find information that is buried in noise. An efficient technique for doing so is called Particle Swarm Optimization. I employed this algorithm in my data analysis research involving gravitational-wave and gamma-ray burst data.
I wrote a demonstration webapp, and my research code uses a C++ implementation. Both are available on my GitHub site.
Extracting information from big data requires a lot of computations. My algorithms were implemented as a C++ parallel program that runs on the Texas Advanced Computing Center's Lonestar 5 supercomputer (under an approved grant).

Apple sleuths hunt Northwest for varieties believed extinct
by Gillian Flaccus, The Associated PressPULLMAN, Wash. — A team of amateur botanists is combing parts of the Pacific Northwest in search of long-lost apple varieties.
The non-profit Lost Apple Project hopes to rediscover varieties of apples long thought to be extinct that may still be growing in forgotten orchards.
Most of the apples they have found in eastern Washington and northern Idaho were planted by white settlers who moved west in the mid- to late-1800s.
So far, David Benscoter and E.J. Brandt have found 13 long-lost apple varieties and taken cuttings so they can be cloned and grown once more for future generations.
But the two are racing against time. The apple trees are a century or more old and are dying. And in other cases, old orchards are being ripped out for farming and development.

Homer: Yeah. There's a lot more mucus.
Many works like to feature exotic animals, and nothing is a cooler way to introduce a weird beast than by using it for transportation. One unusual class of mammals with natural potential for transport are marsupials - after all, they come with their own pockets. And every so often, a character gets the bright idea of using that potential, and climbs into the pouch of a fast-moving pouched creature, typically a kangaroo. A few short hops later, character is safely at their destination, ready to resume the plot.
Given that a marsupial's pouch is something like an incubator for its embryonic infants much of the time, and is very rarely empty of young, this trope means Artistic License Biology. Extra discredit if the marsupial is supposed to be male: the pouch is part of the female reproductive suite. In truth, trying to ride in a kangaroo's pouch would get a much... squickier result.
Even if the kangaroo is indeed female and not carrying young, unless the intended passenger is a small Talking Animal itself, there just wouldn't be room to hitch a lift.
A Sub-Trope of Kangaroos Represent Australia. Compare Horse of a Different Color, Fur Is Clothing and Pelican Package Pouch.
Examples:
- While there are no kangaroos in Pokémon per se, there are Kangaskhan. They are much larger and exclusively female. In an episode of the anime, they adopt and raise a human child who could easily fit inside the pouch. Furthermore, as seen in the end of the episode, the pouch could fit the child, his birth parents, and a baby Kangaskhan, with room to spare. Kangaskhan are officially depicted as 7'03'' in size, but the Kangaskhan in this episode was easily 15 to 20 feet tall to pull that feat off.
- Lupin III and his right-hand man, Jigen, use this in at least one episode to make their getaway. Because how else would the world's greatest thief make a grand escape in Australia?
- The Cartoon History of the Universe, when talking about the spread of Cro-Magnons throughout the world, shows a map including, in Australia, a woman riding in a kangaroo's pouch. The kangaroo looks a bit puzzled about this.
- A panel in The Far Side features Hannibal's first attempt at crossing the Alps. It involves his men riding kangaroos along the narrow ledges (with predictable results).
- Pearls Before Swine had Rat do this in an attempt to conserve energy.
- Minions: In their search of England, the Minion clan makes a short trip in kangaroo pouches when they reach Australia.
- In the children's movie Napoleon, the title puppy is given a ride through the Australian outback in a kangaroo pouch.
- The Goodies. When the Goodies start their own pirate postal operation, Graham says he's ordered several hundred kangaroos for parcel post delivery. This is an early indication that he's going loony.
- Subverted in one of Alan Dean Foster's Spellsinger novels when the intelligent kangaroo has a large, powerful, ill-tempered genie living in her pouch.
 The "male kangaroo with marsupial pouch" mistake is one of the many errors in the kid's stories.
- Subverted in Sterling Lanier's The Unforsaken Hiero. Giant kangaroos are used as mounts in D'alwah, but people ride on their backs with highly specialized saddles.
- In Winnie-the-Pooh, Rabbit kidnaps Roo by dropping Piglet into Kanga's button-up pouch when she isn't looking (they're about the same size, so she just thinks Rabbit put Roo in for her). Piglet doesn't enjoy the ride at all.
- In Deltora Quest Dread Mountain, the heros meet a small number of creatures called the Kin, large, winged, intelligent creatures whom were hunted to near extinction by the Gnomes and Grey guards respectively. After rescuing one of their young three of the largest of the Kin volunteer to fly the characters to the titular mountain in their pouches.
- In The Pride of Parahumans Aniya is a "rescue-taur" type parahuman with opossum genes and an airtight pouch on her lower body that can fit most humans or parahumans in case one's helmet breaks while on a spacewalk.
- This early 90s song by a Dutch children's choir.
- Played straight in The Legend of Zelda: Oracle Games with Ricky the kangaroo, who appears to be male. Of course, like all anime and Japanese game kangaroos, he wears boxing gloves.
- Happens in Yoshi's Island DS.
- Averted in Bomberman; in games where Louie is present, Bomberman rides on his back.
- In Mega Man X7, one Maverick Boss, Vanishing Gungaroo, is based on a joey, and he uses a Mother Kangaroo-like Ride Armor, the cockpit being on its pouch.
- Much like in the anime; when you allow a Kangaskhan to follow you in Pokémon Let's Go Pikachu! and Let's Go Eevee!, your partner will snuggle in the pouch beside the joey. The player character avoids this by hitching a ride on her shoulder instead.
- Happens in the infamous ''Dr. Rabbit's World Tour'' as seen in many YouTube Poops. And somehow the kangaroo hops all the way from Australia to the United States without breaking a sweat...
- Erfworld: The nation of Jetstone uses "cloth golems" — large, animated plushies — as heavy war machines. The so-called "Tankeroos" are used as mounts with this technique; justified, since they're custom-built for this purpose.
- Faux Pas references this trope (and the differences in roo gender) here.
- Not so much a kangaroo as a vaguely feline marsupial alien but in Last Res0rt Jigsaw's Robot Buddy Gangrel usually hides in her pouch, where she also keeps a Bag of Holding.
 Guess where he hides when he gets scared.
- Justified with Adrian and her son Ali in A&H Club as they're anthropomorphic kangaroos.
- In Orion's Arm, Siberoos are kangaroo-Siberian tiger splices that were engineered as rescue animals in polar regions. Females can carry passengers and keep them warm at the same time.
- Deconstructed in The Simpsons; Bart and Homer try to ride one but soon discover that, unlike cartoons, real kangaroos have mucus in their pouches and can't accommodate anything bigger than their joeys.
- Also deconstructed in Family Guy. Peter climbs into the pouch of a kangaroo, but the poor kangaroo can barely move.
Peter: Come on ma, let's go watch Pooh trick the bees outta their honey by pretending he's a rain cloud. *the kangaroo collapses in exhaustion*
- Schoolhouse Rock!, "Rufus Xavier Sarsaparilla." The titular character gains a pet kangaroo and rides around this way.
- In The Wild Thornberrys, a kangaroo once allows Eliza to travel this way as a favor. It's a little more realistic since Eliza is shown crammed in the very tiny pouch.
- Futurama: Bender's Game had orc spear-throwers riding in giant war-kangaroo pouches. A baby kangaroo was hanging around with the orcs in the pouch.
- Happens with giant-sized kangaroo monsters in an episode of Courage the Cowardly Dog.
- Looney Tunes:
- In the cartoon Daffy Duck Slept Here, Daffy claims that he has an invisible kangaroo named Hymie.  Even so, Porky still doesn't buy it.
- Bugs Bunny gets "adopted" by a kangaroo in one episode who insists he ride in her pouch — which has a zipper on it.
- On The Flintstones, Hoppy frequently gives Bamm-Bamm these.
- Johnny Bravo: After getting stranded in an Australian wildlife park, Johnny gets adopted by a mother kangaroo, who puts him in her pouch when the herd moves, much to his annoyance. He actually fits fine, despite being an adult human who is a good deal more muscular than average, his main problem is that the jumping makes him carsick.
- Dot and the Kangaroo (and its sequels) has a whole song about it. The mother kangaroo had lost her baby, thus leaving her pouch empty and she is elated to have Dot ride in it because it reminds her of the feeling of having a child.
The best fun in the world/ And I tell you it's true/ Is to ride in the pouch of a red kangaroo.
- The World of David the Gnome does this once. It is either a kangaroo or a wallaby. (Of course, with a six-inch-tall gnome, this makes sense.)
- One episode of Danger Mouse had DM and Penfold being given a pouch ride by a male kangaroo. Due to the Cosgrove Hall animators sometimes being forgetful when it came to DM and Penfold's size, they were about human size in this part.
- Sonic the Hedgehog (SatAM): Dulcy the dragon has a pouch for her passengers.
- In The Fairly Oddparents episode "Nega Timmy," the Bad Parent Hunter, a parody of the late Aussie Steve Irwin, a.k.a. the Crocodile Hunter, rides in a kangaroo's pouch at the start of his show.
- In one episode of Jackie Chan Adventures, Jackie Chan and Kid Sidekick Jade try to claim the Monkey talisman, one of the twelve talismans that grants the user to change themselves and others into the shape of any animal. A series of shape changing shenanigans occur between the heroes and Valmont's mooks, until Chan is accidentally transformed into a kangaroo and Jade into a rabbit. After beating up the villains in his kangaroo form, he puts rabbit-Jade in his pouch and tries to make a jumpy getaway. Considering that in a later episode, Jade used it again to transform herself into a maned lion, the talisman presumably alters gender as well.
- Laff-A-Lympics: One episode features a kangaroo race as the last event. Subverted because the only entrant to ride his kangaroo's pouch is Mumbly, who uses a mechanical kangaroo instead of a real one, which isn't against any rules.
- A 1980s Gumby episode, "Kangaroo Express," had an Australian equivalent to the Pony Express, where kangaroos carry small parcels across Australia in their pouches. Thanks to Gumby's portable Shrink-a-Dink device, Gumby and his friends can ride in one of the kangaroos.
- My Big, Big Friend: Bongo gives these to Matt from time to time.
- Dragon Tales: In one episode, Max climbs in his dragon friend Ord's pouch in order to complete a connect the dots puzzle while flying.
- Roo is sometimes seen doing this from time-to-time in Kanga's pouch in the various Disney Winnie-the-Pooh productions.
- On Rocko's Modern Life, the intro begins with the titular character as a baby being carried in his mother's pouch (fittingly, he's a wallaby.)
- In the episode where he goes to the laundromat, the washer he's using becomes unbalanced and starts hopping away, and he has to subdue it. It continues hopping along with him on it in this fashion, until he takes a baseball bat and destroys it.
- Puppy Dog Pals: Bingo and Rolly hop in the pouch of two Kangaroos in the episode Bob's Boomerang.
- Widget the World Watcher: In the episode "Widget's Walkabout" the title character transforms into a kangaroo and invites one of his friends to ride in his pouch.
- Although there have been no real life incidents of humans riding in marsupial pouches, the extinct Diprotodon (a sort of giant wombat) had a backward-facing pouch large enough to carry an adult human. A fossil discovery has placed this creature in the spotlight.


Additional Responses in OpenAPI
Warning
This is a rather advanced topic.
If you are starting with FastAPI, you might not need this.
You can declare additional responses, with additional status codes, media types, descriptions, etc.
Those additional responses will be included in the OpenAPI schema, so they will also appear in the API docs.
But for those additional responses you have to make sure you return a Response
like JSONResponse
directly, with your status code and content.
Additional Response with model
¶
You can pass to your path operation decorators a parameter responses
.
It receives a dict
, the keys are status codes for each response, like 200
, and the values are other dict
s with the information for each of them.
Each of those response dict
s can have a key model
, containing a Pydantic model, just like response_model
.
FastAPI will take that model, generate its JSON Schema and include it in the correct place in OpenAPI.
For example, to declare another response with a status code 404
and a Pydantic model Message
, you can write:
from fastapi import FastAPI
from pydantic import BaseModel
from starlette.responses import JSONResponse
class Item(BaseModel):
id: str
value: str
class Message(BaseModel):
message: str
app = FastAPI()
@app.get("/items/{item_id}", response_model=Item, responses={404: {"model": Message}})
async def read_item(item_id: str):
if item_id == "foo":
return {"id": "foo", "value": "there goes my hero"}
else:
return JSONResponse(status_code=404, content={"message": "Item not found"})
Note
Have in mind that you have to return the JSONResponse
directly.
Info
The model
key is not part of OpenAPI.
FastAPI will take the Pydantic model from there, generate the JSON Schema
, and put it in the correct place.
The correct place is:
- In the key
content
, that has as value another JSON object (dict
) that contains:- A key with the media type, e.g.
application/json
, that contains as value another JSON object, that contains:- A key
schema
, that has as the value the JSON Schema from the model, here's the correct place.- FastAPI adds a reference here to the global JSON Schemas in another place in your OpenAPI instead of including it directly. This way, other applications and clients can use those JSON Schemas directly, provide better code generation tools, etc.
- A key
- A key with the media type, e.g.
The generated responses in the OpenAPI for this path operation will be:
{
"responses": {
"404": {
"description": "Additional Response",
"content": {
"application/json": {
"schema": {
"$ref": "#/components/schemas/Message"
}
}
}
},
"200": {
"description": "Successful Response",
"content": {
"application/json": {
"schema": {
"$ref": "#/components/schemas/Item"
}
}
}
},
"422": {
"description": "Validation Error",
"content": {
"application/json": {
"schema": {
"$ref": "#/components/schemas/HTTPValidationError"
}
}
}
}
}
}
The schemas are referenced to another place inside the OpenAPI schema:
{
"components": {
"schemas": {
"Message": {
"title": "Message",
"required": [
"message"
],
"type": "object",
"properties": {
"message": {
"title": "Message",
"type": "string"
}
}
},
"Item": {
"title": "Item",
"required": [
"id",
"value"
],
"type": "object",
"properties": {

"title": "Detail",
"type": "array",
"items": {

}
}
}
}
}
}
}
Additional media types for the main response¶
You can use this same responses
parameter to add different media types for the same main response.
For example, you can add an additional media type of image/png
, declaring that your path operation can return a JSON object (with media type application/json
) or a PNG image:
from fastapi import FastAPI
from pydantic import BaseModel
from starlette.responses import FileResponse
class Item(BaseModel):
id: str
value: str
app = FastAPI()
@app.get(
"/items/{item_id}",
response_model=Item,
responses={
200: {
"content": {"image/png": {}},
"description": "Return the JSON item or an image.",
}
},
)
async def read_item(item_id: str, img: bool = None):
if img:
return FileResponse("image.png", media_type="image/png")
else:
return {"id": "foo", "value": "there goes my hero"}
Note
Notice that you have to return the image using a FileResponse
directly.
Info
Unless you specify a different media type explicitly in your responses
parameter, FastAPI will assume the response has the same media type as the main response class (default application/json
).
But if you have specified a custom response class with None
as its media type, FastAPI will use application/json
for any additional response that has an associated model.
Combining information¶
You can also combine response information from multiple places, including the response_model
, status_code
, and responses
parameters.
You can declare a response_model
, using the default status code 200
(or a custom one if you need), and then declare additional information for that same response in responses
, directly in the OpenAPI schema.
FastAPI will keep the additional information from responses
, and combine it with the JSON Schema from your model.
For example, you can declare a response with a status code 404
that uses a Pydantic model and has a custom description
.
And a response with a status code 200
that uses your response_model
, but includes a custom example
:
from fastapi import FastAPI
from pydantic import BaseModel
from starlette.responses import JSONResponse
class Item(BaseModel):
id: str
value: str
class Message(BaseModel):
message: str
app = FastAPI()
@app.get(
"/items/{item_id}",
response_model=Item,
responses={
404: {"model": Message, "description": "The item was not found"},
200: {
"description": "Item requested by ID",
"content": {
"application/json": {
"example": {"id": "bar", "value": "The bar tenders"}
}
},
},
},
)
async def read_item(item_id: str):
if item_id == "foo":
return {"id": "foo", "value": "there goes my hero"}
else:
return JSONResponse(status_code=404, content={"message": "Item not found"})
It will all be combined and included in your OpenAPI, and shown in the API docs:
Combine predefined responses and custom ones¶
You might want to have some predefined responses that apply to many path operations, but you want to combine them with custom responses needed by each path operation.
For those cases, you can use the Python technique of "unpacking" a dict
with **dict_to_unpack
:
old_dict = {
"old key": "old value",
"second old key": "second old value",
}
new_dict = {**old_dict, "new key": "new value"}
Here, new_dict
will contain all the key-value pairs from old_dict
plus the new key-value pair:
{
"old key": "old value",
"second old key": "second old value",
"new key": "new value",
}
You can use that technique to re-use some predefined responses in your path operations and combine them with additional custom ones.
For example:
from fastapi import FastAPI
from pydantic import BaseModel
from starlette.responses import FileResponse
class Item(BaseModel):
id: str
value: str
responses = {
404: {"description": "Item not found"},
302: {"description": "The item was moved"},
403: {"description": "Not enough privileges"},
}
app = FastAPI()
@app.get(
"/items/{item_id}",
response_model=Item,
responses={**responses, 200: {"content": {"image/png": {}}}},
)
async def read_item(item_id: str, img: bool = None):
if img:
return FileResponse("image.png", media_type="image/png")
else:
return {"id": "foo", "value": "there goes my hero"}
More information about OpenAPI responses¶
To see what exactly you can include in the responses, you can check these sections in the OpenAPI specification:
- OpenAPI Responses Object, it includes the
Response Object
. - OpenAPI Response Object, you can include anything from this directly in each response inside your
responses
parameter. Includingdescription
,headers
,content
(inside of this is that you declare different media types and JSON Schemas), andlinks
.

public class AccessibleRelation extends AccessibleBundle
Class AccessibleRelation describes a relation between the object that implements the AccessibleRelation and one or more other objects. The actual relations that an object has with other objects are defined as an AccessibleRelationSet, which is a composed set of AccessibleRelations.
The toDisplayString method allows you to obtain the localized string for a locale independent key from a predefined ResourceBundle for the keys defined in this class.
The constants in this class present a strongly typed enumeration of common object roles. If the constants in this class are not sufficient to describe the role of an object, a subclass should be generated from this class and it should provide constants in a similar manner.

Yes, it's buggy. And it plays weak. But that's not the point. It's a rather unlikely demo.
This chess game has been written using BootsFaces, the JSF library bringing responsive design to the JSF world. Running on BootsFaces 0.8.0 and above, it uses AJAX a lot.
To unlock the full power of the chess engine, you have to run the game on your local server (the URL must contain localhost or <IP_ADDRESS>). Otherwise, the game assumes it's running on a public server and limits its settings to an economy mode. A decent default setting is look-ahead=6, calculation breadth=7 and multithreading=true. But even so, there a more powerful chess engines out there.
Currently known bugs:
BootsFaces. A great look and feel for JSF. And a lot of fun.


Nowadays, resolving security issues has become Priority #1 in the crypto industry.
It won’t hurt to recall the cases of massive hacker attacks on centralized exchanges that made users lost huge amounts of funds due to security breaches. If it’s pretty clear with centralized services, then what about cryptocurrency wallets?
The hype around crypto has activated scammers and frauds looking for quick and easy methods to take advantage of credulous users' funds.
Custody risks related to the centralized crypto services have made people to find robust means to securely store their funds, and the means are to be invulnerable to hacker attacks.
These risks endanger the safety of your funds, may cause inconvenience, or give you a sense of insecurity.
These wallets are similar to safes, except that all your funds are encrypted in the blockchain. Just like you open the safe with a code, you get access to your funds using your seed phrase.
Small tip: You can store a larger amount of your funds on the cryptocurrency wallet, and also store a smaller part on exchanges for everyday use to prevent yourself from hacking and vulnerabilities of the centralized exchanges.
There are two main types of cryptocurrency storage — cold and hot storages.
The hot method enables you to manage your crypto online and spend them at any time. Such wallets require access to the Internet, as they are supporting permanent connection with the blockchain.
The cold method represents a hardware wallet designed for funds storage without the need for internet connection. You can use a personal computer, phone, flash card or just a piece of paper. However, the hardware wallets are considered to be the most secure.
Choosing the proper secure wallet is an important and responsible step. You must realize that the security of your cryptocurrency assets depends directly on your choice. The most reliable method of storage is when you get full control over your funds, i.e. own the private key.
Atomic Wallet is a cold wallet type, all passwords and data are stored on the user’s device and it is not kept at any server, so there is no custody risks or the possibility of losing funds through centralized services. The main risk in Atomic Wallet is if you lose your backup phrase or send it to another person.
The first stage of Atomic security is password. User create it by himself, the password is required to confirm transactions, to view the list of your private keys and it serves as the primary protection against unauthorized use of the wallet by another person.
But what if you’ve lost your password? Well, here comes the second security stage in the Atomic Wallet Security system — the 12-word Backup Phrase.
Randomly generated 12-word Backup Phrase will help you to restore access to your Atomic Wallet at any time. It is vital not to lose this phrase, store it in a secure and inaccessible to other people place. You can even write it down or print it on a sheet of paper.
This 12-word phrase is a cypher that contains information about private keys and addresses. Seed decipher all symbols for each coin. So with 1 seed you can gain access to all your funds.
Randomly generated 12-word Backup Phrase will help you to restore access to your Atomic Wallet at any time. It is vital not to lose this phrase, store it in a secure and inaccessible to other people place. You can even write it down or print it on a sheet of paper.
In Atomic Wallet, all data stored on the user device or sent when interacting with blockchains is fully encrypted. Local data secured with AES symmetric encryption algorithm and the data which is transferred via BitTorrent protocol or interacting with blockchains is secured with TLS asymmetric encryption.
Advanced Encryption Standard (AES) is a symmetric block cipher chosen by the U.S. government to protect classified information and is implemented in software and hardware throughout the world to encrypt sensitive data.
Transport Layer Security (TLS) is a protocol that provides privacy and data integrity between two communicating applications. It’s the most widely deployed security protocol used today and is used for Web browsers and other applications that require data to be securely exchanged over a network, such as file transfers, VPN connections, instant messaging and voice over IP.
Your safety is fully in your hands. We do not store any data on any servers, we do not store private keys and we do not have access to them. Therefore, it is the users themselves who are responsible for maintaining their password and backup phrase.
At the same time, Atomic Wallet is a combination of complicated cutting-edge technologies, design and security solutions. We built up a fully secure and convenient platform for users that can protect their funds and keep them in a safe place. We chose the way of decentralization, which always corresponded to the spirit of the cryptocurrency. Yes, there are certain drawbacks, but we are fully confident that our platform will attract the attention of many people, our wallet is simple, easy to use, supports a huge number of assets and implement an Atomic Swap technology.


This illustrates the fact that $\mathbb{R}P^1$ is homeomorphic to
$S^1$. Here we regard $S^1$ as the space of complex numbers $z$
with $|z|=1$. Recall that $\mathbb{R}P^1=S^1/E$, where $uEv$ iff
$v=\pm u$. A point of $\mathbb{R}P^1$ is an equivalence class for
this relation, or in other words a pair of opposite points in
$S^1$, as shown on the left. Given a single point $z\in S^1$, as
shown on the right, the two square roots of $z$ form an
equivalence class, as shown on the left. By dragging the right
hand point you can see how the left hand pair varies continuously.


--- layout: archive title: Zulip Chat Archive permalink: /stream/113488-general/topic/how.20do.20I.20step.20through.20proofs.3F.html ---
I want to be able to step through the type checker on a proof the same way I could step through the execution of a program in a debugger. When reading a proof on paper, there is uncertainty about what exactly is going on and the meaning of symbols. In principle, the benefit of computer proofs is that this ambiguity goes away. I've been trying to understand the proofs in mathlib. For instance, the proof that sqrt(2) is irrational, and the proof that the reals are uncountable. I have VSCode setup with lean, and see the goal outputs and types when I put my cursor at places in these proofs. I'm finding that I'm still largely guessing at what each line is doing. In the end it seems no different than reading a proof on paper. I'm wondering if Lean provides any additional debugger tools that let me step through every single step the type checker goes through?
Perhaps #explode
might help break the proof down a bit more
If proofs are written in tactic mode then it's easy to step through them. If they're in term mode, or in tactic mode but with semicolon separators, then it's harder but you can often find out more by deleting terms and replacing them with a _
, which can sometimes persuade lean to tell you the type of the term which is supposed to go in the hole.
My understanding of the question is that he is not happy with the level of detail provided by tactic proofs
#explode
is helpful, but it is not interactive. I have to manually explode every definition used in the proof. Yes I wish it were possible to step through tactic meta programming, as well as see the proof checker state at every step, analogous to seeing all the local variable state in a debugger. That would at least allow me to figure out exactly what any line of code does in principle, though it may be very tedious.
When is Metamath proof explorer getting ported to Lean? :)
This is a good question; I don't know how to reasonably support an explorer type interface to #explode
using the tactic / vscode tricks available to us in lean. We could always generate tens of thousands of html files like metamath does, but I think it would be much more appropriate for lean to have some pull based API where the pages are only constructed as they are requested.
Is there any thought being given to adding the kind of debugger I'm describing to lean in the future?
I don't understand what this hypothetical feature does
I suppose there are two features:
1) A debugger to step through tactic metaprogramming would be like a typical code debugger, if i understand the language correctly.
2) I think what I'm asking for is to be able to step through the execution of the proof checker, and have each step in that execution be tied to some position in user-facing code, i.e. any lean code involved in the proof (e.g. mathlib definitions, axioms, theorems, etc). Like a debugger, I would also want the checker state to be surfaced somehow, so that I can see what the checker sees. I don't have much of an understanding of the inner workings of the proof checker, so I don't know to what extent this is feasible.
Two major difficulties with 2):
simp
or ring
, can produce proofs where even the proof term itself is essentially not comprehensible, let alone the process of checking the proof term. There simply is no more comprehensible layer below the level of these tactics. (That's not to say such a layer could not exist, just that it does not exist with the way these tactics are implemented currently.)I think there is a fallacy here that if you have access to more detail, it will give you greater understanding of what is happening. That is not necessarily the case when the amount of information is overwhelming and where the nature of the information is not more humanly accessible than the original form.
It would help to have some examples of what you would hope to get out of such a tool.
For example if you're completely new to lean and you want to understand proofs of things like p ∧ (q ∧ r) ↔ (p ∧ q) ∧ r
, that's a different matter.
But no amount of tracing the type checking of quadratic_reciprocity
is going to tell you why quadratic reciprocity is true.
Needless to say, I beg to differ. While the way in which lean sees these proofs is not readily accessible to human readers, this is more a presentation issue than anything else. I strongly believe that it is important to retain some connection to what is happening at the low level. If you give that up, the proof checker starts to fall into "magic" territory, and there is no longer a reason to believe in its trustworthiness
At the very least, there is an abstract formalism associated with lean (c.f. my thesis), and it should be possible to present any lean term as a proof in that system
Sure, it's just that quadratic reciprocity will be incomprehensible to a human if you look at it that way.
currently we aren't there yet, because there is no way to trace definitional equality proofs
You're much better off reading a book.
It is possible that the proof of quadratic reciprocity has gone past what people can read, but I would submit that if this is the case then it's a bad proof
I'm very confused by all of this!
There is no reason why a proof of quadratic reciprocity should be incomprehensible
even in full formal detail
If you look at a metamath proof, it is probably more than one would care to write by a factor of about 10 or so, but not more than that. This is within the range of human understanding
All I'm saying is that the proof you actually write in the proof assistant is more comprehensible than what you get by trying to examine, say, the proof term generated by the tactic. Isn't that the purpose of a high-level proof language?
the thing is, proof terms are not a good way to present proofs
because what people actually care about are the types
Right, but this is what was asked for.
Well, not the term per se, but something even worse.
something even better
Well, maybe we have different interpretations of the question then.
proof terms without the typing information requires the user to hold the whole context in their head at all times, which requires ridiculous attention to detail
you can't jump around in a proof like that
which is what humans do
#explode
tries to fill that gap by presenting the types of each intermediate term, and mostly hiding the proof term itself
but it still has nothing to say about definitional unfolding
I think the question asked is probably not the real intended question anyways
and I think you're trying to answer the real intended question
Or maybe not. I have no idea.
I think that #explode
has some limitations since it is non-interactive, and a more debugger like interface would be good, but there are a lot of unanswered UI and implementation details to that
One maybe easy option would be a tactic-ifier that takes any lean proof (as a term), and reconstructs an apply
based tactic proof of it
then you could use the goal view to see all the intermediate states
That sounds really cool.
I was responding to the statement of 2). I still am fairly certain that given a tactic mode proof, there is no amount of visibility into things which actually currently happen during the processing of that proof that will give a greater understanding of what is happening in the proof than to just step through the tactic steps and watch the goal window.
maybe with some rare exceptions for tactics like solve_by_elim
that tend to produce comprehensible proofs
Many tactics are too high level to be able to follow how the goal changed
And this will only get worse as tactics improve
if I see a proof by magic
then following your approach I have no recourse but to just believe
I think the original question is based on a faulty analogy. If we pretend proofs are like programs then stepping through the checking of a proof is like stepping through the compilation of a program. This is not a good way to try to understand a program. (It might be a good way to debug your compiler.)
The computer says it's OK so it's OK. I can completely understand what ring
is doing and I have no interest in learning about horner form.
It's amusing that you say that because I find the analogy extremely accurate
That's because you're not a mathematician
Right, but the proposed approach is not necessarily going to help with those mystery tactics either. That is what I tried to address with my parenthetical sentence.
so you think about maths in a different way. If you want to actually get somewhere you have to learn to fly.
Which analogy is accurate?
It's not so much stepping through the compilation but rather stepping through the low level assembly that comes out the other end
stepping through the compilation would be debugging the tactic itself
I still think you're reading the question as what you want it to be and not as what it actually says.
that's quite possible. I have strong views on this topic and they may be clouding my reading
2) I think what I'm asking for is to be able to step through the execution of the proof checker, and have each step in that execution be tied to some position in user-facing code, i.e. any lean code involved in the proof (e.g. mathlib definitions, axioms, theorems, etc). Like a debugger, I would also want the checker state to be surfaced somehow, so that I can see what the checker sees.
I think it would be hard to relate the steps in the checker (the kernel) to code written in the source text (the tactics), because of the two step compilation process. However, it should be possible to relate tactics to bits of the proof term, and bits of the proof term to checker steps
It's also probably true that what you want the question to be is the same as what the asker wanted the question to be, but without the original asker here we can't really know.
The recently added show_term
tactic will show an individual tactic's contribution to the resulting proof term
Another thing along these lines that would be neat is to make simp
or rw
(with many rewrite steps) output a calc
-style proof
I don't really know whether that's trivial or difficult.
I think a better primitive than calc
would be a conv
proof where the only steps are descending into subterms and transitivity

There are a few scopes which are not related to the content.
Dynamic Scopes
Presently I think only dyn.selection
is available. This allow key bindings which are only active when there is a selection. One example of this could be to overload the tab key to shift right, only when text is selected.
Another example is the “Wrap in Braces” command in the included Avian bundle. This is bould to {
and indents the selection plus puts braces on first/last line.
Other dynamic scopes planned: dyn.caret.(begin|end).(line|document)
. This will allow keys/snippets to only trigger when caret is at the beginning/ending of the line or document.
SCM Scopes
The SCM system used is available as scm.attr.«name»
. A few more SCM scopes are available, for Git the current branch, and status (although that is presently not standardized).
Other
The path is available (reversed) as attr.rev-path.«path»
. This is so that we can bind to e.g. attr.rev-path.erb
to target all files with an ERb extension. This is more relevant for events or injection than key bindings.
OS version is available. This allows us to have different versions of the same command for different OS versions (sometimes easier than testing for the OS version in the command when there is little code sharing between the two versions).

resizeterm 3x
NAME
resizeterm - change the curses terminal size
SYNOPSIS
#include <curses.h>
int resizeterm(int lines, int columns);
DESCRIPTION
This is an extension to the curses library. It provides
callers with a hook into the ncurses data to resize win-
dows, primarily for use by programs running in an X Window
terminal (e.g., xterm). The function resizeterm resizes
the standard and current windows to the specified dimen-
sions, and adjusts other bookkeeping data used by the
ncurses library that record the window dimensions.
When resizing the windows, the function blank-fills the
areas that are extended. The calling application should
fill in these areas with appropriate data.
The function attempts to resize all windows. However, due
to the calling convention of pads, it is not possible to
resize these without additional interaction with the
application.
RETURN VALUE
The function returns the integer ERR upon failure and OK
on success. It will fail if either of the dimensions less
than or equal to zero, or if an error occurs while
(re)allocating memory for the windows.
NOTES
While this function is intended to be used to support a
signal handler (i.e., for SIGWINCH), care should be taken
to avoid invoking it in a context where malloc or realloc
may have been interrupted, since it uses those functions.
If ncurses is configured to supply its own SIGWINCH han-
dler, the resizeterm function ungetch's a KEY_RESIZE which
will be read on the next call to getch. This is used to
alert an application that the screen size has changed, and
that it should repaint special features such as pads that
cannot be done automatically.

wresize(3x).
AUTHOR
Thomas Dickey (from an equivalent function written in 1988
for BSD curses).

Universal won’t be cited for electric shocks at water park
ORLANDO, Fla. (AP) - Federal investigators say Universal Orlando Resort won’t be cited for electrical problems that led to lifeguards getting shocked at its water park, saying the resort was unaware something was wrong.
The Occupational Safety and Health Administration says in a report released this week that five lifeguards reported receiving electric shocks last June at the Volcano Bay water park. The lifeguards were taken to a hospital for observation after they reported feeling tingling in the water. They were released the same day.
A Universal official told investigators that engineers measured 20 to 30 volts on a sidewalk. The cause was found to be electrical wiring damaged during construction that sent electrical current through the ground.
Universal spokesman Tom Schroder says the problem is resolved and the park is safe.

Tennis is unique from other sports with the fact that there are no "home games" for the players and all tournaments take
place in different cities throughout the world. Players on the Women's Tennis Association (WTA) tour typically spend 10+
months of the year on the road, which could include weekly change of climates and altitudes.
All top players compete in the big tournaments, but the choice to go to a smaller one could be dictated by a variety of
reasons:
Such frequent travel can lead to the accumulatation of fatigue that could negatively influence performance. Medical
professionals state that jet lag, sleep interruptions, and altitude changes can result in miscoordinated performance,
if there is no adequate time for adjustment. The magnitude of this effect is unknown, but this research evaluates the
rate at which the top 30 players earn points per kilometers traveled.
The author analyzes the full 2018 tennis season of the WTA for the year-end top 30 players, who are in the best position
to overcome the drawbacks of travel because of their:

New Rule of Thumb: In order to be in the top 10, a player generally needs to achieve travel efficiency rate of 1 point for every 20km traveled.
There are 2 callouts for this efficiency measure:
Overall, this research confirms that the top players maintain very high travel efficiency - they collect more points on average for
their travels and are no "journeywomen", but focused professionals playing on a "smart schedule" in order to
achieve the maximum returns at the least physical expenditure.
Because tennis is played on a single tour internationally and not in a conference/regional format, the players have developed very strong habits
and defense mechanisms to offset travel-related predicaments from changing time zones, climates, and altitudes. This is why they also rarely bring
issues of travel in their interviews, as reported by sports journalist Nick McCarvel
(read full interview here).

Human Practices
Collaboration with Let’s Talk Science
In an effort to extend our reach into our university and city communities, the University of Ottawa iGEM Human Practices Team partnered up with Let’s Talk Science for the 2014 season. Let’s Talk Science is an award-winning, national organization that creates and delivers programs to engage youth and educators in science, technology, engineering and math (STEM). As a team, we recognized that our interests as Human Practices overlapped with the interests of Let’s Talk Science in educating youth about the possibilities that science, including the field of synthetic biology, brings. We established communication with the Ottawa Chapter of Let’s Talk Science and a great partnership was established for the 2014 season.
Through our collaboration with LTS, we were able to set up an iGEM station at the Let’s Talk Science Challenge, an annual event that brings together a large group of students from Grades 6, 7 and 8. These students participate in a science trivia competition for the first half of the day and face-off in a design challenge later in the day. By setting up a station at this event in Ottawa, we were able to reach tens of elementary-aged students and introduce them to the concepts of synthetic biology in a fun and engaging manner (see below). In return, our iGEM Team members volunteered their time to help score both the trivia competition and the design challenge.
Furthermore, in the context of this partnership, a few members of our Human Practices Team were able to participate in a training workshop offered by Let’s Talk Science to improve their skills as youth science educators. This served to enhance our ability to communicate science concepts to the general public, specifically to a young audience.
As an established organization in the Ottawa community, Let’s Talk Science had prior contact with elementary, middle and high schools across the city. They were able to advertise our offer of synthetic biology-oriented presentations to these schools and the response was huge and immediate. To learn more about these classroom presentations, click here.
Classroom Presentations
In addition to participating in Let’s Talk Science and community events, our collaboration with Let’s Talk Science also allowed us to extend our outreach to students in public schools. This is profound because the classroom setting allows us to teach students in an environment of learning where distractions, such as those present at community events, are minimal. And the earlier students are exposed to synthetic biology and science in general, the less time they have had to have been influenced by the plethora of misconceptions about science that are circulating in the public sphere. Very often adults assume that young children are incapable of grasping or appreciating the beauty and elegance of scientific ideas but they could not be more wrong. In fact, children’s minds are far more open than those of adults allowing them to circumvent the problem altogether.
We discovered that teachers whole-heartedly agree with our sentiments about presenting synthetic biology to students early on, after receiving dozens of requests to give in-class presentations within the first few days of having our presentations advertised by Let’s Talk Science. Despite the fact that we were not able to meet an overwhelming demand for presentations, we managed to reach several elementary and middle schools and the response from the teachers and students was resoundingly positive. Students’ questions were never-ending and the teachers’ feedback always included a request to return and do more activities.
During the one-month period that we had to plan and carry out the activities, we managed to do three presentations at three different schools and received wonderful feedback from all three schools. Once schools open up again this September, we will resume our activities in the classrooms to allow us to reach an even greater number of students.
Fairs and Festivals
Engineering Family Fair Day (University of Ottawa)
In March 2014, as part of National Engineering Month, the University of Ottawa organized the Engineering Family Fair Day. Multiple booths featured tools and activities to showcase engineering to the general public, including young kids. The uOttawa iGEM team was invited to participate and we set up a booth of our own where we displayed our children’s book (Human Practices Project 2013) and guided participants through multiple activities including DNA base pair matching exercises and “DNA bracelet” making. We even talked to some young students about possible careers in synthetic biology and related fields.
The Ottawa International Children’s Festival
In May 2014, the uOttawa iGEM Team ran educational science activities at the International Children’s Festival in Ottawa. Children of various ages visited our table to read Mr. Cool’s Microscopic Adventures and make bracelets spelling their names based on aDNA/amino acid code! Throughout the day, we were able to disseminate fundamental biological concepts such as mitosis, meiosis and amino acid code to the students. The students were extremely receptive to the novel ideas that the activities offered. Both parents and students found the activities to be unique and creative, which made the science not only detailed but fun as well.
The Mayfair Community Carnival
Every year, Farley Mowat Public School in Ottawa hosts the Mayfair carnival and invites families from across Ottawa to take part. Over the years, the Mayfair has grown from a small school fundraiser to a community-wide, must-attend event. This year, the uOttawa iGEM Team was there to run activities for kids and talk to the families about iGEM and synthetic biology. We prepared fact sheets about our iGEM Team and handed them out to attendees. We chatted with the parents as the kids enjoyed making DNA out of marshmallow and candy, among other activities. Our booth was a huge hit and it was so rewarding to see the looks of awe on the kids’ faces as they twisted the DNA double helix they had just constructed.
We also had the pleasure of chatting with the Mayor of Ottawa, Mr. Jim Watson, who attended the carnival and visited our booth.
University Course Design
Inspired by universities around the world who have already integrated synthetic biology courses in their curricula and by our own belief in the importance of exposing undergraduate students to the emerging field of synthetic biology, our iGEM HP team has helped put a synthetic biology course in the works at the University of Ottawa. As a team, we researched various topics and put together a first draft of the course outline, after which we handed it over to our team instructor and faculty member Dr. Mads Kaern, who will be moving the idea forward.
To gauge interest in a synthetic biology course, our team also designed and administered a survey to students at the University of Ottawa. The primary results were overwhelmingly positive.
Some student comments we received as part of the survey:
“I think this course could be really practical!”
“This sounds so cool. I wish I wasn’t graduating so I could stick around and take this class.”
“I think this is [a] fantastic idea for a course and I hope it generates enough interest to become a reality!”
“Great idea, hope this pans out.”
Enrichment Mini-Courses Program
The Enrichment Mini-Courses Program offers talented middle school and high school students from Eastern Ontario and Western Quebec the opportunity to explore a field of interest in a university setting. Each year, nearly 3000 students participate in this weeklong program and the University of Ottawa is a major participating post-secondary institution. This year, the uOttawa iGEM team did three presentations as part of EMCP courses. We did presentations in both English and French versions of the “Detectives in Genes/Jeans” course and a presentation in “The Wonderful World of Electronic Imaging.” Our presentations featured activities such as DNA extraction from strawberries, exploration of synthetic gene network design using Lego and building marshmallow animals to learn about meiosis. Throughout the course of these presentations, we reached around 100 students and had a great time doing it.
In fact, we enjoyed this experience so much that we are now in talks to design and run our own enrichment mini-course program. Preparation starts up again this fall and we are ready to get involved.
OGEM
The Ontario Genetically Engineered Machine (oGEM) conference was held in Toronto on Aug 9-10. The conference aimed to further develop the iGEM competition and involved the discussion of topics relevant to this purpose among the five Ontario iGEM teams.
Based on the presentations given by each team, all Human Practices (HP) projects incorporated high school outreach in some way. Thus, in order to stand out from other teams, it was suggested that HP projects should be linked to the application of the wet lab project. This would help iGEM teams have a more integrated and collaborative team effort since the wet lab and HP projects would be tightly linked.
Another major area of discussion involved the development of an undergraduate-level, ‘Introduction to Synthetic Biology’ or even iGEM-specific course. The course would potentially teach students the basics of synthetic biology and related lab techniques, as well as crucial aspects of the iGEM competition and how to give an effective presentation. The overarching idea is that it would be a preparatory course for students wishing to pursue careers in synthetic biology, thus opening up a career pathway which does not exist as of yet.
The course would also address two very common problems that iGEM teams face: spending valuable months training new students and lacking developed ideas at the beginning of summer. If the course were implemented, the iGEM teams would potentially have students who know all the basic lab techniques they need to hit the ground running. Also, if these students were to begin working on a project throughout the duration of the course or simply have had the opportunity to develop ideas, they would have a project that they could begin working on immediately once the iGEM season starts.
Furthermore, one of the most promising ideas raised at the conference was to link iGEM teams with industry. After all, iGEM teams are trying to solve real-world problems using synthetic biology and industries have the knowledge of what problems exist and need to be solved. It was discussed that Dennis, the coordinator of oGEM, will work on establishing contacts with industries and will subsequently match these industries with iGEM teams at a conference that would take take place in January of 2015. This conference would allow both industries and iGEM teams to communicate what it is that they can provide in this partnership. This would give the iGEM teams several months to develop their ideas and would allow HP teams to brainstorm ideas for projects related to the wet lab, since the wet lab project would be already known by the beginning of summer.
In addition to serving as a liaison between industry and individual iGEM teams, Dennis will also be able to provide assistance to iGEM teams by connecting them to services they might require such as an up-to-date database of bacterial strains that can be viewed by all iGEM teams. In an effort to establish and maintain a strategic and long-term industry partnership, each team will assign an oGEM Delegate who will be the contact point for Dennis to communicate the interests of industries with. To continue the collaborative effort to further expand iGEM, an advisory board will be formed which will allow PIs interested in teaching and research to coordinate long-term collaborations with industries and create a nurturing environment for synthetic biology to thrive and flourish.
YouTube Videos
Building on our goal from last season to spread and promote synthetic biology to the general public, this season’s team worked on creating YouTube videos to engage a much larger audience. These videos consist of ideas ranging from simple science-based experiments to answering frequently asked questions. The team was also able to give a small glimpse of the ongoing projects in the lab and outside of it. Despite the fact that we are not professional actors or TV show hosts, we filmed the videos with the hope that our viewers enjoy watching these videos just as much as we enjoyed making them and laughing at our amusing bloopers in the process.
The Human Practices team believes that simple community outreach could go a long way in the future. Our goal is to share something we feel very passionately about with the public, and that is science. For this reason, the team continues to promote synthetic biology and to make it more accessible to others, even if our efforts go to inspire just one curious mind.

Children’s Book
Since the publication of Mr. Cool’s Microscopic Adventures in 2013, we have received positive reviews from both parents and children. This year, our team took this project a step further by translating the book to French to help us reach children who speak the second official language of Canada. We did our best to maintain the rhyming scheme of the book so that it could continue to be both fun and educational for young students.

My name is Juan Munoz. I was born in Peru but moved to a small town in Ohio called Washington Court House when I was seven years old. I am one of four children in my family and I am the only male. I am a USA Air Force veteran. I work full-time at The Ohio State James Cancer hospital. I am currently in school going for a Geographic Information Science degree and I am taking a web developing boot-camp course.
On my free time I love hanging out with my friends and prior to COVID-19 I would enjoy going out for dinner and drinks. Before the pandemic I would travel to various parts of the world for vacation which allowed me to try different types of cuisines that I now enjoy. This has only made me want to keep trying different foods. I have a very eclectic taste in music and I have been lucky enough to see various artist live. I consider myself a cinephile and throughout these past few months I have been able to watch multiple films that I previously did not have time to watch.
I also love to hike at state or national parks whenever I get the chance. I have actually driven across America twice stopping at multiple National Parks. It was such an amazing experience I was able to share with one of my best friends. We would backpack through these parks and make our own fires so we could eat. We made our way to California going up North first and then we would come back down south stopping in various national parks. Some of my favorite National Parks have been: Arches National Park, Redwoods National Park, and Zion National Park. I also enjoy hiking at parks around Ohio and I have to say that Glen Helen in Yellow springs is my favorite.
