The library has been tested using Agda 2.6.1 and <IP_ADDRESS>.
Highlights
-
First instance modules, which provide
Functor
,Monad
,Applicative
instances for various datatypes. Found underData.X.Instances
. -
New standardised numeric predicates
NonZero
,Positive
,Negative
,NonPositive
,NonNegative
, especially designed to work as instance arguments. -
A general hierarachy of metric functions/spaces, including a specialisation to ℕ.
Bug-fixes
-
Fixed various algebraic bundles not correctly re-exporting
commutativeSemigroup
proofs. -
Fixed bug in
Induction.WellFounded.FixPoint
, where the well-founded relation_<_
and the predicateP
were required to live at the same universe level.
Non-backwards compatible changes
Changes to the Relation.Unary.Closure
hierarchy
-
Following the study of the closure operator
◇
dual to the□
operator originally provided, theRelation.Unary.Closure
modules have been reorganised. We have- Added the
◇
closure operator to.Base
- Moved all of the
□
-related functions into submodules called□
(e.g.reindex
→□.reindex
) - Added all of the corresponding
◇
-related functions into submodules called◇
(e.g.◇-reindex
)
- Added the
-
Added functions converting back and forth between
□
-based and◇
-based statements in.Base
:curry : (∀ {x} → ◇ T x → P x) → (∀ {x} → T x → □ P x) uncurry : (∀ {x} → T x → □ P x) → (∀ {x} → ◇ T x → P x)
Other
-
The
n
argument to_⊜_
inTactic.RingSolver.NonReflective
has been made implict rather than explicit. -
Made the first argument of
[,]-∘-distr
inData.Sum.Properties
explicit rather than implicit. -
Data.Empty.Polymorphic
andData.Unit.Polymorphic
have been redefined usingLift
and the original non-polymorphic versions, rather than being defined as new types. This means that these are now compatible with⊥
and⊤
from the rest of the library, allowing them to be used where previouslyLift
was used explicitly.
Deprecated modules
-
The module
Induction.WellFounded.InverseImage
has been deprecated. The proofsaccessible
andwellFounded
have been moved toRelation.Binary.Construct.On
. -
The module
Data.AVL
and all of its submodules have been renamed toData.Tree.AVL
. -
The module
Reflection.TypeChecking.MonadSyntax
has been renamed toReflection.TypeChecking.Monad.Syntax
.
Deprecated names
-
The proofs
replace-equality
fromAlgebra.Properties.(Lattice/DistributiveLattice/BooleanAlgebra)
have been deprecated in favour of the proofs in the newAlgebra.Construct.Subst.Equality
module. - In order to be consistent in usage of \prime character and apostrophe in identifiers,
the following three names were deprecated in favor of their replacement that ends with a
\prime
character.Data.List.Base.InitLast._∷ʳ'_

New modules
- The direct products and zeros over algebraic structures and bundles:
Algebra.Construct.Zero Algebra.Construct.DirectProduct Algebra.Module.Construct.DirectProduct.agda
- Substituting the notion of equality for various structures:
Algebra.Construct.Subst.Equality Relation.Binary.Construct.Subst.Equality
- Instance modules:
Category.Monad.Partiality.Instances Codata.Stream.Instances Codata.Covec.Instances Data.List.Instances Data.List.NonEmpty.Instances Data.Maybe.Instances Data.Vec.Instances Function.Identity.Instances
- Predicate for lists that are sorted with respect to a total order:
Data.List.Relation.Unary.Sorted.TotalOrder Data.List.Relation.Unary.Sorted.TotalOrder.Properties
- Subtraction for binary naturals:
Data.Nat.Binary.Subtraction
- A predicate for vectors in which every pair of elements is related:
Data.Vec.Relation.Unary.AllPairs Data.Vec.Relation.Unary.AllPairs.Properties
- A predicate for vectors in which every element is unique:
Data.Vec.Relation.Unary.Unique.Propositional Data.Vec.Relation.Unary.Unique.Propositional.Properties Data.Vec.Relation.Unary.Unique.Setoid Data.Vec.Relation.Unary.Unique.Setoid.Properties
- Lexicographic relations over vectors:
Data.Vec.Relation.Binary.Lex.Core Data.Vec.Relation.Binary.Lex.NonStrict Data.Vec.Relation.Binary.Lex.Strict
- Properties for functional vectors:
Data.Vec.Functional.Properties
- Modules replacing
Function.Related.TypeIsomorphisms
using the newInverse
definitions:Data.Sum.Algebra Data.Product.Algebra
- Basic properties of the function type
A → B
:Function.Properties
- Symmetry for various functional properties:
Function.Construct.Symmetry
- A hierarchy for metric spaces:
Function.Metric Function.Metric.Core Function.Metric.Definitions Function.Metric.Structures Function.Metric.Bundles
The distance functions above are defined over an arbitrary type for the image. Specialisations to the natural numbers are provided in the following modules:
Function.Metric.Nat Function.Metric.Nat.Core Function.Metric.Nat.Definitions Function.Metric.Nat.Structures Function.Metric.Nat.Bundles
and other specialisations can be created in a similar fashion.
- The type-checking monads:
Reflection.TypeChecking.Monad Reflection.TypeChecking.Monad.Categorical Reflection.TypeChecking.Monad.Instances Reflection.TypeChecking.Format
- Indexed nullary relations/sets:

- Symmetric transitive closures of binary relations:
Relation.Binary.Construct.Closure.SymmetricTransitive
- Composition of binary relations:
Relation.Binary.Construct.Composition
- Generic
printf
method:Text.Format.Generic Text.Printf.Generic
Other major changes
- The module
Relation.Binary.PropositionalEquality
has recently grown in size and now depends on a lot of other parts of the library, e.g. theAlgebra
hierarchy, even though its basic functionality does not. To allow users the options of avoiding specific dependencies, some parts ofRelation.Binary.PropositionalEquality
have been refactored out into:Relation.Binary.PropositionalEquality.Properties Relation.Binary.PropositionalEquality.Algebra
These new modules are re-exported by
Relation.Binary.PropositionalEquality
and so these changes should be invisble to current users.

ObjectPool stores objects of a particular type in the OPM and keeps track of which objects are free and which are in use.
Object pool contains methods for reserving and releasing pooled objects and for manipulating the capacity increments of the data structures (pool supports both growing and shrinking based on increment size), computing the count of free objects, setting the threshold and increment values, and performing cleanup.
This class is currently NOT THREAD SAFE.

Noosa Heads is located just north of the sunshine coast. Most of the surrounding land is national park, so the area is very secluded and private. The town itself is quiet and the water in the bay is calm. It is a great place to get away from life.


An ongoing issue in the digital age
Online Piracy is an issue that has been around since the beginning of the digital age. The various facets of this problem are bound to be prevalent within our everyday lives as the world becomes more and more dependent on the internet. Regardless of whether someone is a producer or consumer of digital content, it is inevitable that they will come across this issue in some way, shape or form - and whilst an initial reaction may be negative towards online piracy, there are many factors that contribute to why it happens, and various outcomes that could be both beneficial and detrimental.
This website provides a collection of resources that discuss the multiple sides and effects of Online Piracy, and how society has responded to this prevailing issue. The topics and relevant resources can be found by following the topic links, or by going to the Topics page.

Tired of getting mushy or dry rice? Use calculator below to cook better rice consistently.
The "first-knuckle" method works... until you get a pot that is too wide or rice that isn't too forgiving with water margins.
I've since moved on from that method and went with a more consistent approach: using a kitchen scale.
First get a cheap digital kitchen scale (eg. CDR King, Lazada) then measure the following:
Enter those values to the calculator along with the following:
Press Calculate to calculate the ideal values for the weight of uncooked rice as well as the whole pot with water included.
Too much water? Lower the ratio by 0.1 - 0.2 next time. Do the reverse if the rice is too dry.
Not enough rice? Increase the average rice or add extra people to the count.
Rice water boiling over and making too much of a mess? Wash the rice 1-2 times more.
Rice sticking to the pot? Assuming you have added enough water, you should let the rice at Keep Warm or off the cooker for a longer time before taking rice to let the remaining moisture settle and soften the dry crust.


Here Is A Triumph List And Guide For Destiny 2’s Harbinger Seal Title
by Paul TassiWhile I am just a few days away from getting the Undying title, you technically can already get Harbinger, now that the dungeon has arrived, as everything you need from the moon is present and accounted for. The problem? When you Google what the Harbinger triumphs are, most of the top results are ads for paid “Seal carriers” where someone will do it for you for the low, low price of hundreds of dollars, which seems wild.In an effort to knock those down the Google front page, I am going to write my own Harbinger Title triumph list and guide here real quick, as hopefully this will help you get the Seal the legit way instead of paying some rando and/or scam site to do it for you.
1. Lunar Rover (Badge)
So, this one is sort of complicated because it actually contains some of the other triumphs on this list, as the items required for the “Moon Gear badge” are rewards for many of them.
You need the Moonrider One sparrow from doing all of Eris’s lost fireteam quests. You need the Pulse Rifle which only drops from the dungeon. The Bane of Tyrants ship is a random dungeon drop with a very low chance. I got it my first try, don’t be mad. The other random ones we will get to over the course of this guide.
2. Nightmare Hunt Time Trial Master
This is probably one of the hardest triumphs on the list. You need to beat every Nightmare Hunt on Master in a set amount of time, except the game doesn’t tell you how much time. Enter my friend Niris, master of infographics, who has all the times listed below which he’s gathered after community testing:
This will get you the A Sibyl’s Dreams emblem that you need for the Lunar Rover badge. This is going to take a lot of trial and error, and beware the boss phases and their repeated immunity that makes them very hard to burst down in most instances.
3. Flawless Master Hunter Nightmare
All you have to do is beat one Master Nightmare Hunt without dying here, which is not too bad. Pick your favorite and go for it. This gets you the Lunar Halcyon Gilt shader you need for the collection badge.
4. Symphony of Death
You need to complete the Deathbringer quest for the exotic launcher that you get after the main moon questline wraps. Here’s a guide from Rick Kackis walking you through the entire thing:
5. Altar’s of Sorrow: Sorrow’s Bane
This gets you the ship The Third Tale for collections which is given for a “perfect” Altars of Sorrow run where no Nightmares get sacrificed, aka they do not make it to the glowing green thing from the other glowing green thing. Hard, but doable. You want a good team.
6. Eternal Heretic
You have to do a flawless run of the new dungeon to get this one. Not solo, but flawless, no deaths. I hear transition glitch deaths do not count against this.
7. Usurper
Now you have to do a solo dungeon run, but it doesn’t have to be flawless. This one you probably do need an actual guide for, so here’s how Gladd did it:
8. Lost No More
You have to find all the lost ghosts on the moon which actually talk to you and have good lore. This gets you the Moonrider One sparrow for the badge. Here’s a guide to their locations from Esoterickk
9. Let Them Eat Rice Cakes
This is feeding Rice Cakes to all the Jade Rabbit statues on the map, similar to feeding cats in the Dreaming City. This gets you the Lunar Gloom shader even though it doesn’t say it in the triumph for some reason. Here’s another guide from Esoterickk for this one:
10. Wandering Nightmares
Each week a different Nightmare will be on the map somewhere that you spawn manually and it shows up at 980. There are four in total. You can solo most if you’re high enough, though you might want to bring a friend. Here’s the locations of all of them from WoW Quests. I do not know the weekly rotation schedule though, so you’ll just want to check around.
Alright, there’s your guide. Please don’t pay anyone to get this. Thanks.

When Covid-19 started to peak many commuters took a break from public transportation of all forms to ensure their safety. As New Yorkers abided by the mandatory stay at home order uber ridership began to decline with non-essential businesses and nightlife attractions being closed.
According to Uber ridership data, the first decline is shown in March with a decrease of 43% which is also when the city was first shut down. This was followed by the greatest decline in April with a decrease of 80%.
William Newman, a Brooklyn-Based Uber Driver said, “I used to be able to complete 100 to 200 rides in one week, but due to the pandemic and new safety procedures my rides have drastically decreased. I actually started to reject rides because the pick-up locations were too far and although the number of rides I receive is growing the business is still not the same.”

EastEnders stars speak out over Emma Barton's Strictly Come Dancing performances
Louisa Lytton, Maisie Smith, Ricky Champ and Rudolph Walker have shared their support for their colleague
by James Rodger, https://www.facebook.com/jamesrodgerjournalistEmma Barton's EastEnders co-stars have given their backing to the "lovable" actress on Strictly Come Dancing.
Her fellow actors believe Barton has been "slaying it" on the BBC show.
Louisa Lytton, Maisie Smith, Ricky Champ and Rudolph Walker have shared their support for their colleague.
They are all taking part in a Strictly special for Children In Need, with Lytton already a veteran of the ballroom floor.
She said of Barton's successful run with partner Anton Du Beke: "I've been watching her, she's doing so well.
"I knew she would anyway, she's so lovable and talented and she's got Anton so I knew she'd be in safe hands."
Smith added: "She's been absolutely slaying it. I saw her earlier and she said it was the perfect bit of reassurance that she needed - it was lovely to see her."
Her co-stars will take part in a charity dance for Children In Need this year, partnering with Luba Mushtuk, Gorka Marquez, Kevin Clifton and Nancy Wu.
Albert Square stalwart Walker will be putting on his dancing shoes at the age of 80.
He will also be backing Barton in her push to triumph in Blackpool in the current series of Strictly.
Walker said: "She is just amazing. It's almost an element of surprise for me seeing a different side to her."
Champ added: "I have been watching Emma and she is brilliant. I love Emma and Anton, I'm rooting for them."
Tess Daly and Claudia Winkleman will present the charity Strictly special on Friday November 15.

F-117 Nighthawk stealth fighter arrives for display at Reagan Library
by John Gregory and ABC7.com staffSIMI VALLEY, Calif. (KABC) -- An F-117 Stealth fighter was towed along Southern California roads to arrive for display at the Ronald Reagan Presidential Library in Simi Valley.
The F-117 Nighthawk, nicknamed "Unexpected Guest," entered service in 1984 during Reagan's presidency. It flew 78 combat sorties, more than all the other F-117s combined, according to the library.
At the time it entered service, Stealth technology was still considered classified and the aircraft were't publicly acknowledged until 1988.
It joins other aircraft on display at the library, including Air Force One. It will be exhibited outdoors, near the library's F-14 aircraft.
Lockheed Martin in the Antelope Valley restored and prepared the aircraft for display.
A formal ribbon-cutting ceremony for the aircraft is expected on Dec. 7.

Catching Up: NatWest Adds More Features to Banking App
by JD AloisThe race to compete with emerging Fintechs is compelling most all banks to up their game. This is good for the consumer. Better service and lower costs (hopefully). If traditional banks want to survive ongoing iterations and a willingness to change is vital. Today, NatWest is updating their banking app with features that are already widely available elsewhere. These include the ability to track spending and automatic categorization. Low hanging fruit in the world of banking.
NatWest Chief Digital Officer Frans Woelders says that the more engaged customers are with their money, the better their financial health.
“The new ‘spending’ feature gives customers insights into their spending habits with real-time data, to help them make informed financial decisions. We want to empower customers to make better decisions and have smarter finances, explained engagingly, simply, from the app that they already use.”
NatWest says they already enable users to view all accounts, even from other banks, within their App – something Open Banking makes simpler to do.
The NatWest app features have been built on tech provided by the European PFM provider, Tink – a Fintecch chosen as a partner for the project due to its experience of developing user-friendly finance apps for banks. Soon, NatWest expects predictive data on spending will be available too.
Expect more features to be added by NatWest in the coming months.

Margin Overview
Margin was formerly known as the Leonardo automated crypto trading bot and the team state that they have been powering Bitcoin trades since May 2014. Leonardo generally disappeared towards the end of 2017, and the protocol has since been purchased by Margin, and the team have integrated many of Leonardo’s bots and key features into their own trading system.
In addition to providing a robust Bitcoin trading platform, the Margin team are also highly professional, and transparent in nature with their information and company structure freely available to view online.
As can be gathered from their website address the project is based in Germany, and the company retains a business address at Goldstrasse 9, 33602 Bielefeld, Germany. The team includes co-founders Jonathan Maycock, Christof Elbrechter, and René Tünnermann who set out to build an easy to use, yet powerful trading terminal, and Margin incorporates a clean layout alongside strong security and a comprehensive range of effective trading bots.
Margin also supports a wide range of leading cryptocurrency exchanges, including Binance, Bitfinex, Bitstamp, Coinbase Pro, Gemini, Huobi, Kraken, KuCoin, and Poloniex.
The application can be run on Windows, macOS and Linux and also provides access to a wide variety of popular technical indicators such as MACD, RSI, EMA, VWAP and Bollinger Bands. The team have provided a demo version which can be downloaded and trialled extensively before moving on to paying for full access, and the Starter plan requires a one-off payment of $129 and offers unlimited bots and all technical indicators on a single exchange (with a max balance of $10,000).
After upgrading to a paid plan, you gain access to the two algorithms that proved popular with users of Leonardo, namely the Ping Pong strategy and the Margin Maker strategy. These allow you to set buy and sell prices and easily get started or to trade according to price action and Margin provides a robust service for traders of all levels.
Key Features
- Functionality – Margin operates as a desktop trading application which supports Windows, Mac, and Linux operating systems. The protocol is well designed and features a configurable GUI that can be used for a multiple monitor setup, as well as light and dark theme options.
- Technology – The platform supports around 17 cryptocurrency exchanges, and anyone can set up automated trades via API integration. Margin also incorporates a range of cutting edge features including visual trading, drag and drop order functionality, in chart RSS feeds, a smart order router, and API encryption and hashing.
- Range of Tools – The platform incorporates the previously popular Ping Pong and Margin Maker strategies which allow anyone to get started quickly with varying levels of complexity. Common market and limit order options are available as are technical indicators such as Bollinger Bands, the Moving Average Convergence/Divergence (MACD), the Relative Strength Index (RSI), Volume Weighted Average Strength (VWAS), and the Exponential Moving Average (EMA).
- Paid Plans – The demo version of the platform can be downloaded and used for free, while the Starter plan is available at a price of $129. The Standard plan is available for $259 and provides access to an unlimited number of bots as well as all technical indicators and supported exchanges. The Professional Plan is priced at $2999 and includes features such as unlimited balances and multiple APIs across exchanges.
- Customer Support – The team behind Margin are one of the most transparent in the world of automated crypto trading platforms and can be contacted by submitting a ticket. The team can also be contacted via their Twitter account, Discord group, and Facebook The official website also contains an FAQ Section, and a series of video tutorials which explain how to use the platform effectively.
How to Get Started on Margin
1) Register an Account
Before downloading the Demo, you are required to register an account on Margin, and you need to enter an email address, create a password and enter your name and location before moving on. You will then need to activate your account by clicking the link in the sent email. When this is done you will gain access to the download link.
2) Download the Demo
You can then download the version suitable for your operating system and Margin supports Windows with 64 and 32 bit versions available, macOS from every version of 10.12 Sierra onwards, and Ubuntu Linux.
Previous Margin releases are also still available for download which will run on older versions of the previously mentioned operating systems. However, the team recommend using a setup which incorporates at least 4GB RAM, a Core 2 Duo processor and a HD display for Windows, macOS and Linux systems. While you can run margin on lower spec machines (e.g. 2GB RAM with a 720p display) it will restrict the number of pairs/bots that can be run effectively.
The demo provides access to:
- Margin’s advanced bots: Bollinger Band, EMA, mArginmaker and ping pong
- Intuitive GUI with drag-and-drop orders and multi-window trading views
- Technical indicators: Bollinger Bands, MACD, RSI, EMA, VWAP etc.
- Free full featured paper trading practice facility
3) Go Live
When you are ready to upgrade to a paid plan, you will need to choose a license, create an API key pair on your exchange account and submit the first half of the secret from the pair to Margin.
When you have submitted your API key info, you need to choose the exchange you want to trade on and then input your full API key and secret to login.
To simplify the process, the team have created the following video tutorial on getting started.
Margin Price Plans
The demo version of the platform can be downloaded and used for free, and the Starter plan is available at a price of $129. This includes to an unlimited number of bots and all technical indicators for use on one exchange with a maximum balance limit of $10,000.
- The Standard plan is available for $259 and provides access to an unlimited number of bots, all technical indicators and all supported exchanges with a maximum balance limit of $100,000 per exchange.
- The Professional Plan is aimed at the most dedicated traders and is priced at $2999 and improves on the Standard plan by including features such as unlimited balances and multiple APIs per each exchange.
Margin currently offers a number of different payment options, including Visa, MasterCard, and PayPal.
How Secure is Margin?
The team behind Margin take security seriously and make use of a variety of methods to ensure the safety of their system. These include the use of SHA 256 encryption and users can also encrypt their API keys by clicking on the lock icon in the login screen and following the instructions.
In addition, the team only store half of any two part API-key pair on their servers and each part remains hashed and encrypted.
The team essentially store just a quarter of a two part API key pair on their servers to ensure that members are paid up customers, and in the event that company servers became compromised, the information held wouldn’t enable hackers to be able to do anything malicious.
Furthermore, orders are also not routed through company servers and Margin connects directly to exchange accounts via an Application Programming Interface (API) which allows it to interface with exchanges, monitor price and account balance data, and, carry out buy and sell orders.
As a result, no one at Margin has any knowledge of your trading patterns, and the instances where the team require communication between your copy of margin and their servers are as follows:
- To check if you are on the correct payment plan
- To retrieve history data which is not available from the exchanges
- To check whether there is an updated version of Margin available
As is common practice for the vast majority of trading bot platforms, Margin doesn’t require you to transfer any funds to your account, and the application does not have access to your funds.
Despite this, the team still advise their users not to not enable withdrawals on their API keys so that it’s impossible for funds to leave any linked exchange accounts.
Finally, the desktop application is also compatible with a VPS or VPN and Microsoft Remote Desktop can be used to connect to your preferred VPS or VPN instance. This way you can continuously monitor exactly how Margin is trading from your PC, phone or tablet, and you won’t need to leave your laptop continuously running.
It’s worth noting that you:
- Should not to run two instances of Margin in parallel and connect to an exchange with the same API key pair.
- Should make sure to set your VPS instance to the same time as the PC/laptop on which you are running Margin, if not your API keys might not work.
- Should make sure your API keys do not have withdrawals enabled.
- Should make use of Margin’s encryption tool in the login screen to encrypt your keys and provide an additional layer of security.
Also data usage when connecting to your VPS instance using a phone or tablet is usually quite high so take this into consideration when using a mobile data plan.
How Beginner Friendly is Margin?
As a desktop trading platform that needs to be downloaded and run from your PC, Margin may take some time to get used to for anyone new to using trading bots, however, the team have made a number of written and video resources available to help guide people through the process. In addition, they are available in their Telegram and Discord groups alongside community members who also possess valuable knowledge and experience.
It’s worth remembering that the Demo version can be downloaded and tested out extensively for free, and includes the mArginmaker and ping pong strategies, advanced bots, a range of technical indicators, and a full featured paper trading practice facility. This allows anyone to get started and spend significant amounts of time testing the application in order to get to grips with it before moving onto a paid plan.
Margin also makes use of well designed user interface and the configurable GUI allows users to select the layout that suits them best, and the visual trading feature allows you to drag-and-drop orders into charts or to hover over a trade to immediately see the gains realized, and RSS feeds are also rendered in-chart to provide an up to date news stream.
Despite aiming to be user friendly, Margin probably has more appeal for intermediate to advanced users and the full range of technical indicators on offer, advanced bots, the ability to view up to 25 markets simultaneously on a second screen, and smart order routing will come in handy for more experienced and highly active traders .
All in all, the application is quite accessible as the demo is available for free, and the Starter plan is available for a one off payment of $129. The Standard plan is available for $259, and anyone new to trading could easily use the demo to get used to using more straightforward strategies such as the Ping Pong Strategy which involves simply setting the buy price and sell prices at which the bot will aim to execute at.
How to Use the Static Ping Pong Bot
The Ping Pong Strategy is one of the most popular trading strategies available on Margin and is also one of the most straightforward to use. The static ping pong bot places limit orders and you can get started by clicking on the strategy button (chess knight with +) to create a new bot.
It will initially default to an effective gain of 0.1% around the spread. In order to select your desired prices you can click and drag the buy and sell price lines, and the bot will wait until its order is fully filled before switching actions to then place a limit order on the opposite side.
In the following illustration, a limit buy order has just been placed and the bot is waiting for the order to become active. A limit sell order for the same amount will be placed on the opposite side when this order gets filled, and in this example an effective gain of just over 3% has been specified.
It’s worth remembering that the bot will continue to trade until you explicitly stop it.
How to Use the Margin Maker Bot
The Margin Maker Strategy is another popular trading strategy and the margin maker bot is a dynamic bot that places limit orders. This bot is more advanced in nature, and allows you to set a number of parameters, for example, the ‘time window’ is set by dragging the long vertical blue line (the thin blue line in the middle of the chart running from top to bottom) to determine the desired time period.
The vertical height of the time window is given by the lowest and highest priced trades that occurred during that time.
The relative buy and sell margins (dashed red horizontal lines) can be set inside this window, and the vertical height of the window changes accordingly, as the lowest and highest trade price changes over time.
This also means that the buy and sell margin prices will change, and as the market contracts, the prices get closer to each other. This also means that the initial Eff. gain* shown in the centre of the time window will also change.
The Min. effective gain [%] parameter applies to both buy/sell and sell/buy cycles here. It is always active, with the default value being 0.0%. In order to ensure that the bot makes a gain once trading fees have been subtracted, a positive value must be given. It’s worth noting that a bot order can get stuck at a particular price so as to not violate the Min. effective gain.
A Stop loss can be enabled and then adapted in the chart, and when a stop-loss event occurs, the bot will accept the loss by triggering a spot sell order and then stopping its trading activity.
Pros
- Transparent Company and Team
- Modern and Configurable GUI
- Extensive Exchange Support
- Free Demo Version
- Wide Range of Options for Advanced Traders
Cons
- Only Supports Bitcoin Trading
- The Application Must be Downloaded
- May be Complex for Beginners
Conclusion
Margin is a serious option for anyone looking to immerse themselves into the world of automated Bitcoin trading. The company and team behind the project are fully transparent, and have made their identities and various social media/LinkedIn profiles publicly available.
They also provide a comprehensive and professional service, and their operations are construed in accordance with and governed by German law, and as a result Margin is a viable choice for anyone looking for a secure solution with a well designed trading interface, and a wide range of options at a reasonable price.
The application is dedicated to trading over 3000 cryptocurrencies across a range of leading exchanges which will suit some traders, while anyone interested in trading a wide range of altcoins will be forced to look for an alternative option.
Margin integrates with over 15 leading exchanges including Binance, Coinbase Pro, Gemini, and Kraken, and also incorporates a variety of cutting edge features such as a visual trading, drag and drop order functionality, in chart RSS feeds, a smart order router, and a configurable GUI.
A good number of these features alongside the range of technical indicators and trading bots available to use will suit intermediate and more advanced traders and the platform is set up to allow more dedicated traders to make the most of their trading activities.
However, the team have made a number of resources available to help guide users through the process of using Margin to make automated trades and these include both written and video guides. Crucially the team are also on hand to discuss any issues in their Telegram and Discord groups alongside more experienced community members which is a valuable resource for anyone still learning.
The need to download and install the application may prove to be a turnoff for some, and there are other trading platforms that can be easily accessed from a web browser such as 3Commas and Cryptohopper, however, the team incorporate a number of sensible security protocols and allow users of Windows, Mac, and Linux to use their protocol.
Once up and running, the popular Ping Pong strategy is quite straightforward to use, and anyone still new to automated trading can get to grips with it in a short space of time.
Most importantly, the demo version can be downloaded and used for free which allows anyone to take as much time as necessary to test out the platform and decide whether it is suitable for them. As ever, it makes perfect sense to engage in paper trading and run numerous simulations with virtual funds before graduating to a live account.
The paid plans on offer are also competitive as they involve one off payments and the Starter and Standard plans amount to around $10.75 and $21.60 a month if you were to use Margin for just one year.
The average cost obviously declines the longer you use the platform and the team aim to attract and retain more dedicated traders who will be happy to fork out for a considerably more expensive Professional plan.
Due to the relatively low costs involved in getting started with Margin, the platform will essentially pay for itself if it helps you to generate even quite moderate profits on a regular basis.
As a result, Margin suits anyone ready to dive deep into the world of automated Bitcoin trading, and take the time to set up and configure the platform in the way that suits them best.
Anyone looking to give learning how to trade Bitcoin a go can download the demo and get started, while more experienced traders can do the same to gain a deeper understanding of how Margin can help them to enhance their current trading activities.

Event Description: Throttle Wars
Bot Specification:
- The vehicle should be designed so that it fits in an 800mm X 700
mm box at any given point of time in the race. This is excluding the
remote controller.
- It is essential that the car be designed with an internal combustion
engine (IC engine). Motors etc. should not be the main driving
sources of the car. However, for steering mechanisms or any other
mechanism apart from propulsion, DC motors and servos can be
used.
- Only one IC engine should be used in the vehicle. Use of any other
sources such as chemicals, compressed gas, rockets etc. for
propulsion is not allowed. The allowed capacity of IC engine to be
used is 4.5 cc or less.
- The vehicle has to be necessarily controlled by a wireless remote
control system throughout the competition. The vehicle must have
two remote controllers of different frequencies or an alternate
frequency remote control circuit which can be switched to either
frequency before the start of the round. This is done to avoid
frequency interference between the two competing vehicles.
- Remote control systems from toys or the ones purchased from a
market might be used without any fear of penalization.
- The vehicle parts can be ready made. But there will be extra points
if you make chassis and steering mechanism by yourself (See
judging criteria for more detail).
- If you are making your own car, then other functional parts like
motors and servos, gears, springs, engine, remote control systems,
batteries, wheels, braking mechanism are allowed to be used as
directly available from the market.
- It is essential that the vehicle has an onboard power supply to
provide electricity to any mechanism requiring electric power.
- Electric voltage not more than 12V should be used in the machine
wherever required.
- Participants are advised to use a proper cooling mechanism to
prevent overheating of the engine.
- Verify with the organizers if you have the slightest doubt whether a
component can be used or not. Please do not hesitate. Designs not
complying with the vehicle specifications will be disqualified.
Arena Specifications
To be released soon.
Rules
- The track will have checkpoints at regular intervals.
- In case a machine tumbles, or halts, or goes off the arena at any
point on the track, only one of the participants is allowed to lift it up
and place it at the nearest checkpoint behind that point. (Previous two
rules are for non-racing rounds. The rules for racing round will be
explained on the spot)
- Until and unless there is a need to touch the vehicle as stated
above, they have to be fully remote controlled throughout the race.
- Every time the machine requires lifting by the team member, a
time-penalty will be imposed.
- Any vehicle is not allowed to leave any disintegrated part on the
race track amidst the race. In case this happens, the team will be
disqualified.
- The teams are also not allowed to damage the opponent's vehicle
deliberately. If found guilty, the accused team will be disqualified.
- There will be a time-penalty for reverse gearing.
- Teams may consist of a maximum of 4 members.
General Rules
- Participants should posses a valid identity card from their respective Institutions
- Depending on the number of teams participating and other time
constraints, the arena will be given to the participants for practicing.
- The time slots will be given on the basis of first come first serve
basis, but a little duration of time for practicing is assured to
everyone.
- Each team must come up with its own, unique team name.
- Organizers reserve the right to change any of the above rules.
- Participants can address their queries via e-mail or forums and
directly by calling up the organizers.
- For help and reference, some material will be uploaded soon.
- The decision of the organizers’ and judges’ shall be considered as
final and binding on all.
- If there are less than 5 teams registered , event will be cancelled.
Judging Criteria:
-
Participants are expected to design their own racing car. In case the
participants use ready-made cars, they will only be evaluated for
3/4th of the total marks i.e a penalty if 1/4th of the total marks will be
levied on them. If their car is part self-designed and part ready-made,
then the marks will be given accordingly as per the judge’s discretion.
Above mentioned penalty is not applicable for the final round.
-
Driving ability and application skills of the participants shall also be
put to test.
-
Lap time will be another criterion to decide the winner.

A model of a four-stroke combustion engine. The driving force is obtained by constructing a looping audio sample, divided into four regions which represent the 4 stages of the engine: An intake stroke, a compression stroke (silence), a combustion stroke, and an exhaust stroke. The intake stroke was modeled as white noise enveloped with a bell curve. The exhaust stroke is modeled as white noise, rapidly decaying in time, inspired by a high pressure gas mixture being released when the valve opens. The combustion stroke consists of an enveloped burst of 1/f noise.
The sample is looped at adjustable rate, corresponding to the running speed of the engine. For added realism the engine is allowed to "misfire" once in a while, which is implemented by skipping a section in the looped sample.
The engine resonance frequencies and dampings can be scaled with the bottom two sliders. When the sound gets too soft press Stop/Start to reset AGC.

To access the procedures in the Tcl library, an application should source the file init.tcl in the library, for example with the Tcl command
source [file join [info library] init.tcl]If the library procedure Tcl_Init is invoked from an application's Tcl_AppInit procedure, this happens automatically. The code in init.tcl will define the unknown procedure and arrange for the other procedures to be loaded on-demand using the auto-load mechanism defined below.
auto_mkindex foo *.tcl
will read all the .tcl files in subdirectory foo and generate a new index file foo/tclIndex.
Auto_mkindex parses the Tcl scripts by sourcing them into a slave interpreter and monitoring the proc and namespace commands that are executed. Extensions can use the (undocumented) auto_mkindex_parser package to register other commands that can contribute to the auto_load index. You will have to read through auto.tcl to see how this works.
Auto_mkindex_old parses the Tcl scripts in a relatively unsophisticated way: if any line contains the word proc as its first characters then it is assumed to be a procedure definition and the next word of the line is taken as the procedure's name. Procedure definitions that don't appear in this way (e.g. they have spaces before the proc) will not be indexed. If your script contains "dangerous" code, such as global initialization code or procedure names with special characters like $, *, [ or ], you are safer using auto_mkindex_old.
Auto_qualify is used by the auto-loading facilities in Tcl, both for producing auto-loading indexes such as pkgIndex.tcl, and for performing the actual auto-loading of functions at runtime.

Sugar Che?
Managing lifestyle disease such as Diabetes through modern technology
Few years back my mom diagnosed with Type 2 diabetes, with blood glucose level 460 mg/dL. That number was a shock because she never imagined that it can be that much high. After that day her lifestyle changed in various levels, like eating food without sugar, exercising, regular glucose monitoring etc. This incident pushed me to work for Diabetic people, with a single aim to make their life easy and enjoyable as possible as I can.
I spent a couple of months and came up with a technological solution such as a medical device for measuring non-invasive blood glucose continuously, ML powered app which can detect sugar directly from a photo of food, futuristic application of various tools etc etc.
I'm sharing a couple of those Ideas and solutions here; which I've conceptualized, designed, developed and tested with few diabetic people.

My Abule
Tweet
"Abule" is a Yoruba word for Village. So, welcome to my village, the Niger Delta. The Niger Delta is the delta of the Niger River sitting directly on the Gulf of Guinea on the Atlantic Ocean in Nigeria. It is typically considered to be located within nine coastal southern Nigerian states, which include: all six states from the South South geopolitical zone, one state (Ondo) from South West geopolitical zone and two states (Abia and Imo) from South East geopolitical zone. Of all the states that the region covers, only Cross River is not an oil-producing state. The Niger Delta is a very densely populated region sometimes called the Oil Rivers because it was once a major producer of palm oil. The area was the British Oil Rivers Protectorate from 1885 until 1893, when it was expanded and became the Niger Coast Protectorate. The Niger Delta region of Nigeria is richly endowed with both renewable and non-renewable natural resources. It contains 20 billion of Africa's proven 66 billion barrels of oil reserves and more than 3 trillion cubic meters of gas reserves. The delta is a petroleum-rich region and has been the center of international concern over pollution that has resulted principally from major oil spills of multinational corporations of the petroleum industry.
The Niger Delta, as now defined officially by the Nigerian government, extends over about 70,000 km2 (27,000 sq mi) and makes up 7.5% of Nigeria's land mass. Historically and cartographically, it consists of present-day Bayelsa, Delta, and Rivers States. In 2000, however, Obasanjo's regime included Abia, Akwa-Ibom, Cross River State, Edo, Imo and Ondo States in the region. The Niger Delta, and the South South geopolitical zone (which contains six of the states in Niger Delta) are two different entities. The Niger Delta separates the Bight of Benin from the Bight of Bonny within the larger Gulf of Guinea.
Some 31 million people of more than 40 ethnic groups including the Bini, Itsekiri, Efik, Esan, Ibibio, Annang, Oron, Ijaw, Igbo, Isoko, Urhobo, Kalabari, Yoruba, Okrika, Ogoni, Epie-Atissa people and Obolo people, are among the inhabitants of the political Niger Delta, speaking about 250 different dialects. Language groups spoken in the Niger Delta include the Ijaw languages, Itsekiri language, Central Delta languages, Edoid languages, Yoruboid Languages, and Igboid languages.
In a research caried out by Vivienne Bamgboye (Lead Researcher), Peter Shiras (IYF Executive Vice President), Dan Oliver, PhD (IYF Business Development Director) Micah Mendie (PIND Analysis & Advocacy Program Coordinator), the Niger Delta generates nearly 80% of Nigeria’s revenue, yet the majority of the population there remains in dire poverty and the region has been beset by violent conflict. Current development efforts and assistance recognizes that much more effort is needed to improve socio-economic conditions in the region if its problems are to be sustainably overcome. No single organization can address these problems on its own and thus the best solutions lie in the establishment of effective multi-stakeholder partnerships.
Our Hopes
We hope that resources can be directed towards the following;
- Capacity-building support for youth-focused NGOs can help them become models of transparency and accountability while they also serve as advocates and service providers.
- Leadership training for youth leaders
- Life skills training with a special consideration for conflict management and resolution positive identity development.
- Technical assistance for youth – focused NGOs to enhance program design and monitoring and reporting.
- Programs that support creativity, innovation and other forms of engagement with youth.
- Entrepreneurship and employability.
- Holistic entrepreneurship development training with a special consideration for apprenticeship and access to finance.
- Business incubators in various industries and sectors including agriculture/aqua- culture to boost innovation and entrepreneurship across the region.
- Holistic employability training programs with an emphasis on career counseling/coaching, on the job coaching and job placement schemes.
- Technical assistance to public sector entities engaged in employability training to ensure that this training is demand-driven, responsive to the needs of private sectors employers and has adequate means to track youth after training, assess job placement and make appropriate programmatic adjustments.
- Early intervention and collaboration with formal educational bodies to raise the quality of education.
- A transparent scholarship scheme to give opportunities to indigent youth particularly youths from rural communities with a view to creating social capital and regress cyclical poverty.
- Leadership and civic education for secondary schools.
- Career counseling at the secondary school level to create realistic expectations for employment and guide youth to further education and training.
Our Challenges
From the research conducted by Vivienne Bamgboye (Lead Researcher), Peter Shiras (IYF Executive Vice President), Dan Oliver, PhD (IYF Business Development Director) Micah Mendie (PIND Analysis & Advocacy Program Coordinator), the majority of youth participants – who were primarily either students or unemployed youth (with a very low percentage of youth in paid employment), although the assessment did include some semi-literate, informal sector workers (such as street vendors or motorcycle delivery vendors) – when asked to state their aspirations, said, “…just to survive.” In Port Harcourt, Bori, and Bayelsa, young people told the assessment team that they try to occupy their time with positive activities such as educational seminars or church activities. There were strong indicators that the youth in urban areas, such as Port Harcourt, Warri, Benin, and Asaba, were trying to “take charge of their lives” by engaging in casual work to earn small amounts of money. During the focus groups in Port Harcourt, most participants also said they did casual work to supplement their income as their families could barely afford to maintain their own costs. Female participants commonly responded that they worked in hairdressing salons or tailoring shops for small salaries. Some participants admitted that they engaged in illegal activities “to survive” because these activities “bring in more money”. Illegal activities mentioned include petty theft, Internet fraud, and selling stolen properties.
These circumstances are brought upon the general populace of the Niger Delta as a result of the following;
- Corruption.
- Militancy.
- Youth seclution from governance.
- Defunct youth empowerment schemes.
- Unprofitable skill acquisition trainings.

WIAA D3: DeForest rolls the dice late, tops Menasha 8-7
by FOX Sports WisconsinDeForest rolled the dice in head coach Mike Minick’s final game at the helm.
It payed off.
The Norskies went for two after scoring their first touchdown of the day in the final minute of the WIAA Division 3 championship game, converting and holding on for an 8-7 win over Menasha and their first title since 2007.
Quarterback Trey Schroeder hit Gabe Finley on a 13-yard touchdown pass with 32 seconds remaining to get DeForest on the board, before floating a jump pass to Nolan Hawk for the two-point conversion.
Schroeder completed three passes on the Norskies’ go-ahead drive, hitting Logan Bierman for 28 yards and Hawk for 11 yards before finding Finley for the score.
For a while, it appeared that Menasha’s first-quarter touchdown would hold up as the game-winner.
Davontre Smith punched in a nine-yard rushing touchdown on the game’s opening drive, a lead that lasted until the final minute of the fourth quarter.
The Bluejays’ defense made plays throughout, piling up seven tackles for loss, five sacks and two interceptions, while recovering a pair of fumbles.

I'm a Raspberry Pi. This is me in my favourite outfit:


As an alternative to the Delaware C Corp, it's designed for businesses where rent extraction is less viable than creating value in and for the underlying assets - for example real estate, ride hailing, or farming.
Its cooperative core leads to better decision making, while retaining the benefits of growth, swift decisions, and standardized operations across geographies. This is not without precedent: the world's largest fund manager, Vanguard, is run in a similar way, as are many other successful companies.
The three core principles are:
The modern economy is a marvel that brought us more than just the iPhone. But over-financialization and the hunt for extractive yields made capitalism not even work for many capitalists anymore. We need to be in this together again and re-align incentives.
As we rebuild, we need to rebuild trust in our institutions, ourselves, and each other.
Everything you need to start your own Purpose Trust will be available in the second half of 2020, in the meantime please do follow our progress on Github.
