Basic Usage
Speaker Notes:
This version of bootstrap has a lot of different installation options. Let's go through them.
Installation Options
Speaker Notes:
-
The fastest way is to use CDNs. A CDN is a content delivery network or a server that hosts libraries like Bootstrap. When using one of these links, the browser checks to see if there's already a copy from when you visited another site.
-
You can also install Bootstrap by downloading the pre-compiled CSS and JavaScript files. That works well if you want to work without an internet connection.
-
You can also download the source files. That means all of the files that the developers used to create bootstrap, which means the original sass files and documentation. You probably only want to do this if you want to contribute to the project or customize bootstrap.
1.The last way is to use a package manager. That means using something like webpack, parcel, npm or others. It's meant for advanced users who want to really customize things.
There's also a special project called the NPM Starter Kit, which you can download at this link. It's an attempt to create a Github repo that you can use as a starter kit, but it's under heavy development.

I normally use the CDN links, unless I know I'm going to work offline. Here's a basic template you can use with the CSS and JavaScript installed.
I sneaked in a copy of Bootstrap Icons in here, which I really enjoy, but it's also optional, so feel free to remove it. I almost always have a tag like the main tag here with a class of container which sets up the basic bootstrap grid and some text.

A stereotype is a widely held but fixed and oversimplified opinion about a person,place,or thing. most of the time stereotyping can happen because people may look at or judge.Others may even stereotype because of past experience.If you or someone you know is being stereotyped , whether it be because of their weight,race,or even gender, here are some tips to get out of that situation!!! The best way to solve this is by simply surrounding yourself with people who are positive.People also always think they have to act and look a certain way, but thats not right! be you! it shoudlnt matter what others think about you, at the end of the day you have the last word on what you think about yourself!
This graph shows the inequality between genders. the pink represents female founders in the work industry , blue represents male founders, and teal represents female and male founders of a company.Only 2.5% of the work indusry are female founders.

valtype::iban - Validation for IBAN
This package implements a snit validation type for an IBAN.
A validation type is an object that can be used to validate Tcl values of a particular kind. For example, snit::integer, a validation type defined by the snit package is used to validate that a Tcl value is an integer.
Every validation type has a validate method which is used to do the validation. This method must take a single argument, the value to be validated; further, it must do nothing if the value is valid, but throw an error if the value is invalid:
valtype::iban validate .... ;# Does nothing valtype::iban validate .... ;# Throws an error (bad International Bank Account Number).
The validate method will always return the validated value on success, and throw the -errorcode INVALID on error, possibly with additional elements which provide more details about the problem.
The API provided by this package satisfies the specification of snit validation types found in the documentation of Snit's Not Incr Tcl.
This method validates the value and returns it, possibly in a canonical form, if it passes. If the value does not pass the validation an error is thrown.
This method computes a check digit for the value. Before doing so it is validated, except for a checkdigit. If the value does not pass the validation no check digit is calculated and an error is thrown instead.
As said in the package description, the errors thrown by the commands of this package in response to input validation failures use the -errorcode INVALID to distinguish themselves from package internal errors.
To provide more detailed information about why the validation failed the -errorCode goes actually beyond that. First, it will contain a code detailing the type itself. Here this is IBAN. This is then followed by values detailing the reason for the failure. The full set of -errorCodes which can be thrown by this package are:
The input value contained one or more bad characters, i.e. characters which must not occur in the input for it to be an IBAN.
The check digit of the input value is wrong. This usually signals a data-entry error, with digits transposed, forgotten, etc. Of course, th input may be an outright fake too.
This document, and the package it describes, will undoubtedly contain bugs and other problems. Please report such in the category valtype of the Tcllib Trackers. Please also report any ideas for enhancements you may have for either package and/or documentation.
When proposing code changes, please provide unified diffs, i.e the output of diff -u.

Language, basic terminology, and concepts¶
Because of the interdisciplinary environment of this endeavour, finding a common language is a challenge bound to lead to misunderstandings and probably unfounded tacit assumptions. In the copan:CORE documentation and implementation, we therefore try to use simple non-disciplinary language wherever possible, and explain our usage of terms that have different meanings in different disciplines as good as possible using a combination of definitions and examples.
Entities, processes, attributes¶
copan:CORE treats the real world as consisting of numerous sufficiently well-distinguishable entities (“things that are”, e.g., a spot on the Earth surface, the EU, yourself, …) [1] that are involved in a number of sufficiently well-distinguishable processes (“things that happen”, e.g., vegetation growth, economic production, opinion formation, …) which affect one or more attributes (“how things are”, e.g., the spot’s harvestable biomass, the EU’s gross product, your opinion on fossil fuels, the ocean-atmosphere diffusion coefficient…).
copan:CORE classifies entities by entity-types (“kinds of things that are”, e.g., grid cell, social system, individual, …, see Entity-types in the copan:CORE base model), and allows to group (some or all) processes into process taxons (environmental, social-metabolic, cultural, …, see Taxonomy of processes).
Processes and attributes “belong to” entity-types or process taxons¶
On the model level, each process and each attribute belongs to either a certain entity-type or a certain process taxon. When talking about processes, people from very different backgrounds widely use a subject-verb-object sentence structure even when the subject is not a conscious being and the described action is not deliberate (e.g., “the oceans take up carbon from the atmosphere”). copan:CORE therefore allows modelers to treat some processes as if they were “done by” a certain entity (the “subject” of the process) “to” itself and/or certain other entities (the “objects” of the process). Other processes for which there appears to be no natural candidate entity to serve as the “subject” can be treated as if they are happening “inside” or “on” some larger entity that contains or otherwise supports all actually involved entities. In both cases, the process is treated as belonging to some entity-type. Still other processes may best be treated as not belonging to any entity but rather as simply belonging to a process taxon (environment, social metabolism, culture, …) [2].
We deliberately do not specify sharp criteria for whether a modeler should treat a certain process as being “done by” or “happening inside” an entity since this is in part a question of style and academic discipline and there will inevitably be examples where this choice appears to be quite arbitrary and will affect only the model’s description, implementation, and maybe its running time, but not its results. An example might be the photosynthesis part of the carbon cycle, which could be described by either saying “plants take carbon from the air” and attaching it to the plant as the subject or by saying “plants’ RuBisCO enzymes and atmospheric carbon dioxide react to form 3-phosphoglycerate” and attaching it to the grid cell it is happening on, or by simply attaching it to the taxon of environmental processes.
Similarly, attributes may be modeled as “belonging to” some entity-type (e.g. “total population” or “territory” might be modeled as attributes of the “social system” entity-type) or to some process taxon (e.g. “diffusion coefficient” might be modeled as an attribute of the “environment” process taxon). We suggest to model most quantities as entity-type attributes and model only those quantities as process taxon attributes which represent global constants.
Formal process-types and data-types¶
Independently of where processes belong to, they are also distinguished by their formal process-type (continuous dynamics given by ordinary differential equations, (quasi-)instantaneous reactions given by algebraic equations, steps in discrete time, irregular or random events, …, see Process-types) that correspond to different modeling and simulation/solving techniques.
Similarly, attributes have data-types (mostly physical or socio-economic simple quantities of various dimensions and units, but also more complex data-types such as “network”). See also metadata below.
Modularization into model components and models¶
copan:CORE aims at supporting a plug-and-play approach to modeling and a corresponding division of labour between several user groups (or roles) by dividing the overall model-based research workflow into several tasks:
- if there is already a model that fits your research question, use it in your study (role: Model end users)
- if not, decide what model components the question at hand needs
- if all components exist, compose a new model from them (role: Model composers)
- if not, design and implement missing model components (role: Model component developers)
- if some required entity attributes are not yet in the master data model (see below), add them to your component
- suggest well-tested entity attributes, entity-types, or model components to be included in the master data model or master component repository (role: Modeling board members)
As a consequence, we distinguish between model components and (composed) models.
A model component specifies:
- a meaningful collection of processes that belong so closely together that it would not make sense to include some of them without the others into a model (e.g., plant photosynthesis and respiration, or capital investment and depreciation, or individuals’ choice of profession and residence)
- the entity attributes that those processes deal with, referring to attributes listed in the master data model whenever possible (e.g., a cell’s terrestrial carbon stock, a social system’s capital stock, an individual’s skill level)
- if really necessary, any additional entity-types not existing in the master data model, and their attributes (e.g., an entity-type “lake” with certain attributes)
A model specifies:
- which model components to use
- if necessary, which components are allowed to overrule parts of which other components (e.g., a “climate policy” component might need to overrule the process “fossil fuel extraction” that was specified by a component “energy sector”)
- if necessary, any attribute identities: whether some attributes should be considered to be the same thing (e.g., in a complex model, an attribute “harvestable biomass” used by the “energy sector” component as input may need to be distinguished from an attribute “total vegetation” governed by a “vegetation dynamics” component, but a simple model that has no “land use” component that govern their relationship may want to identify the two)
The master data model defines entity types, process taxons, and attributes which the modeling board members deem…
- likely to occur in many different models or model components
- sufficiently well-defined and well-named (in particular, specific enough to avoid most ambiguities but avoiding a too discipline-specific language)
The master component repository contains model components which the modeling board members deem… - likely to be useful for many different models - sufficiently mature and well-tested - indecomposable into more suitable smaller components
All attributes are treated as “Variables” with metadata¶
Although many models make an explicit distinction between endogenous and exogenous variables and parameters, there seems to be no clear consensus regarding the exact criteria for such a distinction and the exact definition of those two terms.
In copan:CORE, we made the very pragmatic decision to treat all relevant quantities a priori in the same way, model them as attributes of either entities or process taxons, and simply call them variables, whether or not during a specific model run they turn out to be changing or constant and not changing, or whether they are used for a bifurcation analysis in a study etc.
One reason for this is that a quantity that one model component uses as a “parameter” that will not be changed by this component may easily be an endogenously changed “output” variable of another component. Hence it is not known to a model component developer which of the quantities she deals with will turn out to be changing endogenous “variables” or constant exogenous “parameters” of the various models and studies that use this component. Only a posteriori (after composition of a specific model from model components), one might call those variables that will never be changed from their initial value during any model runs the “parameters” of this model.
A variable’s specification will contain metadata such as
- a common language name (used in human-directed output)
- a description giving its (rough) definition and other relevant textual information
- a mathematical symbol normally used to denote it
- its level of measurement (aka scale of measure, i.e, ratio, interval, ordinal, or nominal)
- its physical or socio-economic dimension (e.g., length) and default unit (e.g., meters), if possible following some established standard (e.g., SI units), but sometimes using more refined distinctions (e.g., the variable “atmospheric carbon stock” has a dimension of “carbon” with default unit “tonnes carbon”, and the variable “human population” has a dimension of “humans” with default unit “people”), and, if applicable, whether the variable is extensive or intensive
- its datatype, a range of possible values (giving non-strict or strict lower and/or upper bounds and/or a quantum for interval- or ratio-scaled variables, or a set of levels for nominal- or ordinal-scaled ones, possibly including the value “none”), a default (constant or initial) value, and an uninformed prior distribution that may be used to generate random values, e.g. for Monte-Carlo simulations
- references (preferably URLs) of any items in existing metadata catalogs that can be (roughly) identified with the variable
- (e.g., a CF Standard Name or a World Bank CETS code)
| [1] | Since many models dealing with processes actually happening on a continuous spatial scale use a more or less fine discretization of space into equally or differently sized, regularly or irregularly arranged units (often called “grid cells”, sometimes “elements”, …), we explicitly include an entity-type “cell” although the partitioning of continuous space into cells may not always be related to well-distinguishable parts of space but rather follow some technical criteria (e.g., a regular latitude-longitude grid rather than an irregular grid derived from the Earth surface’s topography) |
| [2] | The question where a process “belongs” will become important on the software design level: processes belonging to individual entities will be represented by class attributes and instance methods of the corresponding entity-type class, while processes belonging to a process taxon will be represented by class attributes and instance methods of the corresponding process taxon class. |

CIRCLE OF FRIENDS A film review by Jeffrey Graebner Copyright 1995 Jeffrey Graebner
Recently, Ireland has produced a number of interesting and intelligent films. The latest Irish-import, CIRCLE OF FRIENDS, is a smart and charming coming-of-age drama that provides a thoughtful look at the complexities of young romance.
The film follows the romance of Benny (Minnie Driver) and Jack (Chris O'Donnell), two Irish college students experiencing love and romance for the first time. Their romance is contrasted with separate romances experienced by Benny's two closest friends: repressed Eve (Geraldine O'Rawe) and worldly Nan (Saffron Burrows).
Much of the film's appeal comes from the thoughtful and believable way that screenwriter Andrew Davies (working from a novel by Maeve Binchy) has these characters approach issues of relationships and sexuality. The film is set in 1957 and does reflect the more openly conservative values of the time, but the writing still seems contemporary thanks to the writer's recognition that most of the base feelings and concerns in these areas never change all that much.
The movie is at its best when it simply has the main characters talking to each other. We discover that Benny and Jack are right for each other during some wonderful early sequences where they go on walks together and find that they are able to freely talk with one another about anything. The physical attraction between the characters isn't ignored, but the film makes it clear that the emotional and intellectual attraction is what really counts the most.
Davies and director Pat O'Connor wisely keep the secondary romances involving Eve and Nan in the background, only using them to provide counterpoints to the main romance between Benny and Jack. Eve is an orphan that was raised by nuns in a convent, giving her extremely traditional Catholic views. Her romance with another college boy (Aiden Gillen) is marked by an interesting combination curiosity and a desire to remain true to her values. Nan, on the other hand, is much more worldly and quicker to jump head first into a passionate affair with an older man (Colin Firth). Both of these romances are used to contrast Benny and Jack's romance with more extreme examples. A twist in Nan's romance also eventually provides some conflict into several of the film's key relationships.
One refreshing aspect of the film is the very realistic way that religion is included as a major factor in the characters' lives. The girls are all Irish Catholics and many of their conversations include some discussion of the conflict between their religious beliefs and their natural curiosity about sex. It is rare today that a film treats religious values as a subject worthy of thoughtful discussion.
The one major part of the film that doesn't work is an unfortunate subplot involving Sean (Alan Cumming), a clerk at Benny's store who is a rival for her affections. This subplot is very ineptly played and it winds up being an unwelcome distraction. The big mistake is making Sean into an >obvious< villain in the film. Cumming plays him as a smirking, weasily character and O'Connor stages his scenes to make him appear as unflattering as possible. To top it all off, composer Michael Kamen greets his every appearance with obviously sinister music. It is made clear from the start that Benny has no romantic interest in Sean and that he is strictly her parents' choice for her.  The character simply doesn't serve any useful purpose in the film and the time wasted on him could have been better spent developing the relationship between Benny and Jack even further.
Minnie Driver's performance is one of the best reasons to see this film. She is a very smart and charming presence who easily carries every scene that she is in. The film makes the point that she is a bit overweight and generally plain-looking, but she has an inner-beauty that is instantly recognizable. In an early scene, Jack very accurately describes Benny as a "solid" personality who truly knows who she is and what she wants. Driver's very smart and sincere performance clearly conveys this to the audience.
Chris O'Donnell is developing a lot of skill as a strong supporting actor. He is a very generous actor who truly knows when to stand back and let other actors dominate the scene. In this film, Benny is very much the central character and it is important to let Jack be primarily defined by her reactions to him. O'Donnell is able to do this, quietly playing off of Driver's more dominating performance to create an interesting chemistry. It takes a lot of skill for an actor to know when to stay out of the way.
CIRCLE OF FRIENDS is a small, pleasant film with some very thoughtful and intelligent dialog and a tremendously good lead performance by Minnie Driver. The film is marred somewhat by the unfortunate subplot involving the store clerk, but the parts of the film that work are easily able to overcome the parts that don't.

I've experimented with many benzodiazapines in my time. But Clonazepam (Klonopin) I would have to say is the longest lasting of all of them.
At approximatly 7:30 am I swallow a .5 mg Klonopin on my way to class. It doesn't take long to start feeling the effects and by about 7:50 am I am already feeling myself 'Come up' on the drug.  By about 8:15 pm I can already feel myself peaking off of the drug. I feel slightly euphoric, and all of my movements are over-exaggerated, alot like valium or xanax.
During this time I am in my chemistry class taking a test. Suprisingly I am able to focus on it and finish it but I feel rediculously fucked up and still able to enjoy the feeling of the drug. My speech wasn't slurring but I felt like I was almost to that point. My teacher calls on me to ask me a question, and when I look up it feels like the world just flipped upside-down. I would have fallen out of my chair if I wasn't holding onto the table, but miraculously I answer her question and there was no suspicion of my intoxication.
I go through the rest of the day like this, with only a few people noticing me acting a little different. The drug itself was very pleasing, it felt like the effects of a skeletal muscle-relaxant mixed with an opiate like hydrocodone. It lasted all the way up until I went to sleep at around 11 pm. The only downside to this drug that I see is that it is very hard to recall what happened during the time I was on the drug due to amnesia being a common side effect.
Minor effects of the drug still felt the next day. I wish I could tell more but it's very hazy.

X.509 client
certificate
authentication
X.509 auth - overview
- Keycloak supports authentication with client certificates
- There must be certificate authority (CA), which issues client certificates to users
- CA needs to be trusted by Keycloak server (entry in truststore on KC server side)
X.509 - authentication workflow
- User has X509 certificate, signed by trusted CA
- User adds X509 in PKCS12 format to his browser
- User wants to authenticate against Keycloak
- User sends initial request to OIDC/SAML endpoint. Must be HTTPS request
- Keycloak (Undertow subsystem) does mutual SSL authentication. Client identity extracted from client certificate in HTTPS connection
- Keycloak authenticator - more verifications of client certificate and map certificate identity to existing Keycloak user
- User is automatically authenticated by Keycloak (no login form shown) and redirected back to the app
Required actions from admin
- Have CA authority to create client certificates
- Create client certificates and distribute somehow to users
- Setup Keycloak
CA setup and manage certificates
Setup Keycloak
- Create truststore file with CA entry
- Eventually setup other things (CRL, OCSP responder)
- Configure standalone.xml
- Configure X509 authenticator in Keycloak admin console
Configuration in standalone.xml
- Security realm
- Points to truststore file, which need to have entry corresponding to CA used to sign client certificates
- Keystore file - Identity of the server itself
- Undertow subsystem - HTTPS listener pointing to security realm above
Configuration of authenticator
- Done in Keycloak admin console
- Configuration options
- Check revocation status - optional support for CRL or OCSP
- Check "key usage" or "extended key usage" from certificate - also optional
- Extract identity from client certificate
- Map extracted identity to Keycloak user - user must exists. Either map to username/email of existing user or some attribute of existing user
Extract identity from client certificate
- Match SubjectDN using regular expression
- X500 Subject’s e-mail attribute
- X500 Subject’s Common Name attribute
- Match IssuerDN using regular expression
- X500 Issuer’s e-mail attribute
- X500 Issuer’s Common Name attribute
- Certificate Serial Number
X509 client certificate lookup
- Specifies how exactly to lookup certificate from HTTP request
- Provider configurable in keycloak subsystem in standalone.xml
- Builtin options are:
- DefaultClientCertificateLookup - Lookup from attribute of HTTP request standardized by servlet specification. Default option
- ApacheProxySslClientCertificateLookup - Used when Keycloak behind Apache reverse proxy
- HaProxySslClientCertificateLookup - Used when Keycloak behind HAProxy reverse proxy
- Eventual possibility to add own provider (if none of builtin options matches). But SPI not supported
Direct grants support
- Authentication with client certificates in directGrant requests (non-browser requests requesting KC authentication)
- Separate authenticator implementation


AMERICAN BEAUTY A film by Sam Mendes Starring: Kevin Spacey, Annette Bening, Chris Cooper, Mena Suvari, Thora Birch, Wes Bentley, and Scott Bakula. Written by Alan Ball
I have lived in suburbia for most of my life. Most of the time I just walk out the door, and walk to my car, and get in and not realize that things are moving around me. Things are actually happening behind me, but I can never see them, because most of the time I really don't care. AMERICAN BEAUTY changed that perception more than anything else. Sam Mendes' astonishing debut is heartwrenching, hysterical, thoughtful, provocative, controversial, and ultimately, the most rewarding and affirming movie of the year. And it very well could be the best movie of 1999.
Lester Burnham (Spacey) is tired. He is tired of the pain he feels at night, tired of the frustration at his family, his work, and at himself. He is not the man of hopes and dreams he once was. He has, through the Reagan Revolution and the age of capitalism, lost his soul, lost it in something in no longer believes in anymore. Lester probably has more in common with Warren Beatty's delightful Jay Billington Bulworth in BULWORTH than any other character ever created. Like Bulworth, Lester is triggered into the spirit of life by a woman.
The fact that she's a 17 year old cheerleader and classmate of Lester's daughter Jane isn't the point, although it's a wickedly funny plot device. The point is Lester's confrontation with beauty, and the beauty that exists in the universe that he's been avoiding for so many years. So, to the dismay of his WASPish wife Carolyn (Bening), he starts to change. He works out. He quits his job. He smokes pot. And he dreams, at night, of Angela (Suvari).
But AMERICAN BEAUTY wouldn't work nearly as well as it does if this was about Lester. It's about the relationships we have with the people in our lives. And those people vary from our family to our neighbors to even people we don't know but with whom we have a certain link to. And all of these are rich, probing characters in AMERICAN BEAUTY: all of these are facets of the American culture that we inhabit. Col. Fitts (Cooper) and his drug-dealing son Ricky (Bentley) are one of them, and they are by far the most interesting. Others include the King (Peter Gallagher) and, to a lesser extent, a gay couple played by Bakula and Sam Robards.
AMERICAN BEAUTY works so well, in fact, mostly because it's a comedy. This is one hysterical movie, with gags all over the place. But these laughs hurt, because they are directed at us. Lester Burnham is the neo American hero, and as we mock his quest for independence we are ashamed at laughing at him. Some may object to his wild misbehavings, but the truth is that no one can ever expunge 20 years of cultural domination over them cleanly. It takes a mad prophet to change the world, and Lester's my pick for the next one. Of course, to tell you more would be to ruin the glorious ending of this film, where it stops being a good satire, and starts aiming to be a classic masterpiece.
It would be an overblown statement to call this a masterpiece. Certainly, despite the excellent script, there are kinks in the armor, namely the over stereotyping of American subcultures. But in the end, it really does not matter. The script decides to forego the middling material it has and in the last hour, becomes the mad search for redemption in an unforgiving world. All of the characters, we realize, are looking for the same thing: redemption. And are not sure how in the world to find it.
It takes a gutsy performance to make this film work, and Kevin Spacey gives it in the role of his career. This is the role he has been working towards all of his life: the summation of the state of America within a character. And he pulls it off in such dramatic fashion that it will be a travesty if he is not awarded the Best Actor award at the Academy Awards. Annette Bening is sensational, as are all the supporting players. The movie thematically seems to be sure of itself, but is not: it leaves a few holes here and there, and may be too eager to force upon its themes to its audience. No matter. For what its worth, this is a film that truly faces the state of America today. It reexamines beauty and its place in our minds. It is, truly, a beautiful work, one of the best of the year, and is therefore fantastic in its implications. The last act of this work is downright astonishing, as is the far-reaching power of this film. Mendes shows a clear talent for imagery and brings alive a story that demonstrates once and again the tremendous power of film. A glorious achievement.

Getting the hang of Autodesk was kind of hard at first, but I eventually got it. Learning how to extrude was a bit harder. I feel like sketcing with a tablet and a pencil would end up being easier than using a mouse. My hand felt shaky while drawing rectangles and such. A lot of what I did didn't end up working so well, especially when I was trying to flip between axes. I started sketching a bit more of my final project. Overall, Autodesk Fusion 360 worked well!
I made a few different designs. Six of them were given to me from my teacher, Mr. Gerber, and one of the other ones was a hinge. The hinge was probably one of the hardest things to do. Extruding the different parts was good warmup for my other designs, but it ended up taking a bunch of time. I wasn't able to print it, but will soon!
This was the first challenge we had to make during class. We were given about 30 minutes to follow the exact drawn design and translate it into AutoDesk Fusion 360.
This was the hinge I made on Fusion 360. I spent a majority of my time on it, which made it harder to do my other designs below. I used a Youtube Tutorial Video on How To Make a Hinge in Fusion 360 which I found to be very helpful.
These were the 6 out of 50 of the designs we were given to create to help us practice Fusion360. Some of the designs were harder to make than others, but I still got through with most of them. After I finished making them, I felt much more well-versed in using Fusion 360.

still syncing the blocks but its not syncing from the start
its syncing from where it left :
no in the explorer sapling was like - 1
now let me check whether the explorer
and emanuel the explorer didnt start from the beginning
it started from where it left
and i still cant see the blocks
DionPay Insight. View detailed information on all DionPay transactions and block. {{ $root.title + $root.titleDetail }}
i just did the getinfo on cli still the sapling is = -1
i havent stopped the daemon right
"name": "DION",
"sapling": -1,
staking node 1 and staking node 2 shows teh sapling = some height
but inside the explorer it shows different
look i have an explorer server right ?
like explorer is installed on different server
so it got the dion-cli .sh inside it that runs the daemon command
when i run this daemon command just as ./dion-cli getinfo
like when it goes to certain block it goes off
its crashed on certain block height
hope it progresses this time
its because i work for some company
so the boss is yelling at me
and it should get stopped
he gets hyped up i am thinking of leaving the job
cannot work being spaztic i have been sitting at my home since 13 hrs
continuously to resolve the issue
and atlast now stuck on the explorer
true bro
yup same its my intention and passion
but no agression
i am still not a good developer

This section discusses setting up zc.async without Zope 3. Since Zope 3 is ill-defined, we will be more specific: this describes setting up zc.async without ZCML, without any zope.app packages, and with as few dependencies as possible. A casual way of describing the dependencies is “ZODB, Twisted, and zope.component,” though we directly depend on some smaller packages and indirectly on others [1].
You may have one or two kinds of configurations for your software using zc.async. The simplest approach is to have all processes able both to put items in queues, and to perform them with a dispatcher. You can then use on-the-fly ZODB configuration to determine what jobs, if any, each process’ dispatcher performs. If a dispatcher has no agents in a given queue, as we’ll discuss below, the dispatcher will not perform any job for that queue.
However, if you want to create some processes that can only put items in a queue, and do not have a dispatcher at all, that is easy to do. We’ll call this a “client” process, and the full configuration a “client/server process”. As you might expect, the configuration of a client process is a subset of the configuration of the client/server process.
The zc.async.configure module helps with basic configuration. The Quickstart with virtualenv shows an example of using this for a very :quick start. The current text uses some of those conveniences, but focuses more on understanding the underlying patterns, rather than the conveniences.
We will first describe setting up a client, non-dispatcher process, in which you only can put items in a zc.async queue; and then describe setting up a dispatcher client/server process that can be used both to request and to perform jobs.
Generally, zc.async configuration has four basic parts: component registrations, ZODB setup, ZODB configuration, and process configuration. For a client process, we’ll discuss required component registrations; ZODB setup; minimal ZODB configuration; process configuration; and then circle back around for some optional component registrations.
The required registrations can be installed for you by the zc.async.configure.base function. Most other examples in this package, such as those in the Usage section, use this in their test setup.
Again, for a quick start, you might just want to use the helper zc.async.configure.base function, and move on to the Required ZODB Set Up section below.

You must have three adapter registrations: IConnection to ITransactionManager, IPersistent to IConnection, and IPersistent to ITransactionManager.
The zc.twist package provides all of these adapters. However, zope.app.keyreference also provides a version of the connection adapter that is identical or very similar, and that should work fine if you are already using that package in your application.
>>> import zc.twist
>>> import zope.component
>>> zope.component.provideAdapter(zc.twist.transactionManager)
>>> zope.component.provideAdapter(zc.twist.connection)
>>> import ZODB.interfaces
>>> zope.component.provideAdapter(
... zc.twist.transactionManager, adapts=(ZODB.interfaces.IConnection,))
We also need to be able to adapt functions and methods to jobs. The zc.async.job.Job class is the expected implementation.
>>> import types
>>> import zc.async.interfaces
>>> import zc.async.job
>>> zope.component.provideAdapter(
... zc.async.job.Job,
... adapts=(types.FunctionType,),
... provides=zc.async.interfaces.IJob)
>>> zope.component.provideAdapter(
... zc.async.job.Job,
... adapts=(types.MethodType,),
... provides=zc.async.interfaces.IJob)
>>> zope.component.provideAdapter( # optional, rarely used
... zc.async.job.Job,
... adapts=(zc.twist.METHOD_WRAPPER_TYPE,),
... provides=zc.async.interfaces.IJob)
The queue looks for the UUID utility to set the assignerUUID job attribute, and may want to use it to optionally filter jobs during claim in the future. Also, the dispatcher will look for a UUID utility if a UUID is not specifically provided to its constructor.
>>> from zc.async.instanceuuid import UUID
>>> zope.component.provideUtility(
... UUID, zc.async.interfaces.IUUID, '')
The UUID we register here is a UUID of the instance, which is expected to uniquely identify the process when in production. It is stored in the file specified by the ZC_ASYNC_UUID environment variable (or in os.join(os.getcwd(), 'uuid.txt') if this is not specified, for easy initial experimentation with the package).
>>> import uuid
>>> import os
>>> f = open(os.environ["ZC_ASYNC_UUID"])
>>> uuid_hex = f.readline().strip()
>>> f.close()
>>> uuid = uuid.UUID(uuid_hex)
>>> UUID == uuid
True
The uuid.txt file is intended to stay in the instance home as a persistent identifier.
Again, all of the required registrations above can be accomplished quickly with zc.async.configure.base.
On a basic level, zc.async needs a setup that supports good conflict resolution. Most or all production ZODB storages now have the necessary APIs to support MVCC.
Of course, if you want to run multiple processes, you need ZEO. You should also then make sure that your ZEO server installation has all the code that includes conflict resolution, such as zc.queue, because, as of this writing, conflict resolution happens in the ZEO server, not in clients.
A more subtle decision is whether to use multiple databases. The zc.async dispatcher can generate a lot of database churn. It may be wise to put the queue in a separate database from your content database(s).
The downsides to this option include the fact that you must be careful to specify to which database objects belong; and that broken cross-database references are not handled gracefully in the ZODB as of this writing.
We will use multiple databases for our example here, because we are trying to demonstrate production-quality examples. We will show this with a pure-Python approach, rather than the ZConfig approach usually used by Zope. If you know ZConfig, that will be a reasonable approach as well; see zope.app.appsetup for how Zope uses ZConfig to set up multidatabases.
In our example, we create two file storages. In production, you might likely use ZEO; hooking ClientStorage up instead of FileStorage should be straight forward.
>>> databases = {} >>> import ZODB.FileStorage >>> storage = ZODB.FileStorage.FileStorage( ... 'main.fs', create=True)>>> async_storage = ZODB.FileStorage.FileStorage( ... 'async.fs', create=True)>>> from ZODB.DB import DB >>> databases[''] = db = DB(storage) >>> databases['async'] = async_db = DB(async_storage) >>> async_db.databases = db.databases = databases >>> db.database_name = '' >>> async_db.database_name = 'async' >>> conn = db.open() >>> root = conn.root()
All we must have for a client to be able to put jobs in a queue is ... a queue.
For a quick start, the zc.async.subscribers module provides a subscriber to a DatabaseOpened event that does the right dance. See multidb_queue_installer and queue_installer in that module, and you can see that in use in Configuration with Zope 3. For now, though, we’re taking things step by step and explaining what’s going on.
Dispatchers look for queues in a mapping off the root of the database in a key defined as a constant: zc.async.interfaces.KEY. This mapping should generally be a zc.async.queue.Queues object.
If we were not using a multi-database for our example, we could simply install the queues mapping with this line: root[zc.async.interfaces.KEY] = zc.async.queue.Queues(). We will need something a bit more baroque. We will add the queues mapping to the ‘async’ database, and then make it available in the main database (‘’) with the proper key.
>>> conn2 = conn.get_connection('async')
>>> import zc.async.queue
>>> queues = conn2.root()['mounted_queues'] = zc.async.queue.Queues()
Note that the ‘mounted_queues’ key in the async database is arbitrary: what we care about is the key in the database that the dispatcher will see.
Now we add the object explicitly to conn2, so that the ZODB will know the “real” database in which the object lives, even though it will be also accessible from the main database.
>>> conn2.add(queues)
>>> root[zc.async.interfaces.KEY] = queues
>>> import transaction
>>> transaction.commit()
Now we need to put a queue in the queues collection. We can have more than one, as discussed below, but we suggest a convention of the primary queue being available in a key of ‘’ (empty string).
>>> queue = queues[''] = zc.async.queue.Queue()
>>> transaction.commit()
We touched on quotas in the usage section. Some jobs will need to access resources that are shared across processes. A central data structure such as an index in the ZODB is a prime example, but other examples might include a network service that only allows a certain number of concurrent connections. These scenarios can be helped by quotas.
Quotas are demonstrated in the usage section. For configuration, you should know these characteristics:
Since we put our queues in a mapping of them, we can also create multiple queues. This can make some scenarios more convenient and simpler to reason about. For instance, while you might have agents filtering jobs as we describe above, it might be simpler to say that you have a queue for one kind of job–say, processing a video file or an audio file–and a queue for other kinds of jobs. Then it is easy and obvious to set up simple FIFO agents as desired for different dispatchers. The same kind of logic could be accomplished with agents, but it is easier to picture the multiple queues.
Another use case for multiple queues might be for specialized queues, like ones that broadcast jobs. You could write a queue subclass that broadcasts copies of jobs they get to all dispatchers, aggregating results. This could be used to send “events” to all processes, or to gather statistics on certain processes, and so on.
Generally, any time the application wants to be able to assert a kind of job rather than letting the agents decide what to do, having separate queues is a reasonable tool.
You often want to daemonize your software, so that you can restart it if there’s a problem, keep track of it and monitor it, and so on. ZDaemon (http://pypi.python.org/pypi/zdaemon) and Supervisor (http://supervisord.org/) are two fairly simple-to-use ways of doing this for both client and client/server processes. If your main application can be packaged as a setuptools distribution (egg or source release or even development egg) then you can have your main application as a zc.async client and your dispatchers running a separate zc.async-only main loop that simply includes your main application as a dependency, so the necessary software is around. You may have to do a bit more configuration on the client/server side to mimic global registries such as zope.component registrations and so on between the client and the client/servers, but this shouldn’t be too bad.
As discussed above, the instanceuuid module will look for an environmental variable ZC_ASYNC_UUID to find the file name to use, and failing that will use os.join(os.getcwd(), 'uuid.txt'). It’s worth noting that daemonization tools such as ZDaemon and Supervisor (3 or greater) make setting environment values for child processes an easy (and repeatable) configuration file setting.
The only optional component registration potentially valuable for client instances that only put jobs in the queue is registering an adapter from persistent objects to a queue. The zc.async.queue.getDefaultQueue adapter does this for an adapter to the queue named ‘’ (empty string). Since that’s what we have from the ZODB Configuration above section, we’ll register it. Writing your own adapter is trivial, as you can see if you look at the implementation of this function.
>>> zope.component.provideAdapter(zc.async.queue.getDefaultQueue)
>>> zc.async.interfaces.IQueue(root) is queue
True
Configuring a client/server process–something that includes a running dispatcher–means doing everything described above, plus a bit more. You need to set up and start a reactor and dispatcher; configure agents as desired to get the dispatcher to do some work; and optionally configure logging.
For a quick start, the zc.async.subscribers module has some conveniences to start a threaded reactor and dispatcher, and to install agents. You might want to look at those to get started. They are also used in the Zope 3 configuration (README_3). Meanwhile, this document continues to go step-by-step instead, to try and explain the components and configuration.
Even though it seems reasonable to first start a dispatcher and then set up its agents, we’ll first define a subscriber to create an agent. As we’ll see below, the dispatcher fires an event when it registers with a queue, and another when it activates the queue. These events give you the opportunity to register subscribers to add one or more agents to a queue, to tell the dispatcher what jobs to perform. zc.async.agent.addMainAgentActivationHandler is a reasonable starter: it adds a single agent named ‘main’ if one does not exist. The agent has a simple indiscriminate FIFO policy for the queue. If you want to write your own subscriber, look at this, or at the more generic subscriber in the zc.async.subscribers module.
Agents are an important part of the ZODB configuration, and so are described more in depth below.
>>> import zc.async.agent
>>> zope.component.provideHandler(
... zc.async.agent.addMainAgentActivationHandler)
This subscriber is registered for the IDispatcherActivated event; another approach might use the IDispatcherRegistered event.
Now we can start the reactor, and start the dispatcher. In some applications this may be done with an event subscriber to DatabaseOpened, as is done in zc.async.subscribers. Here, we will do it inline.
Any object that conforms to the specification of zc.async.interfaces.IReactor will be usable by the dispatcher. For our example, we will use our own instance of the Twisted select-based reactor running in a separate thread. This is separate from the Twisted reactor installed in twisted.internet.reactor, and so this approach can be used with an application that does not otherwise use Twisted (for instance, a Zope application using the “classic” zope publisher).
The testing module also has a reactor on which the Usage section relies, if you would like to see a minimal contract.
Configuring the basics is fairly simple, as we’ll see in a moment. The trickiest part is to handle signals cleanly. It is also optional! The dispatcher will eventually figure out that there was not a clean shut down before and take care of it. Here, though, essentially as an optimization, we install signal handlers in the main thread using reactor._handleSignals. reactor._handleSignals may work in some real-world applications, but if your application already needs to handle signals you may need a more careful approach. Again, see zc.async.subscribers for some options you can explore.
>>> import twisted.internet.selectreactor
>>> reactor = twisted.internet.selectreactor.SelectReactor()
>>> reactor._handleSignals()
Now we are ready to instantiate our dispatcher.
>>> import zc.async.dispatcher
>>> dispatcher = zc.async.dispatcher.Dispatcher(db, reactor)
Notice it has the uuid defined in instanceuuid.
>>> dispatcher.UUID == UUID
True
Now we can start the reactor and the dispatcher in a thread.
>>> import threading >>> def start(): ... dispatcher.activate() ... reactor.run(installSignalHandlers=0) ... >>> thread = threading.Thread(target=start) >>> thread.setDaemon(True)>>> thread.start()
The dispatcher should be starting up now. Let’s wait for it to activate. We’re using a test convenience, get_poll, defined in the testing module.
>>> from zc.async.testing import get_poll
>>> poll = get_poll(dispatcher, 0)
We’re off! The events have been fired for registering and activating the dispatcher. Therefore, our subscriber to add our agent has fired.
We need to begin our transaction to synchronize our view of the database.
>>> t = transaction.begin()
We get the collection of dispatcher agents from the queue, using the UUID.
>>> dispatcher_agents = queue.dispatchers[UUID]
It has one agent–the one placed by our subscriber.
>>> dispatcher_agents.keys()
['main']
>>> agent = dispatcher_agents['main']
Now we have our agent! But...what is it [9]?
 They pick the jobs and assign them to their dispatcher when the dispatcher asks.
If a dispatcher does not have any agents in a given queue, it will not perform any tasks for that queue.
We currently have an agent that simply asks for the next available FIFO job. We are using an agent implementation that allows you to specify a callable to filter the job. That callable is now None.
>>> agent.filter is None
True
What does a filter do? A filter takes a job and returns a value evaluated as a boolean. For instance, let’s say we always wanted a certain number of threads available for working on a particular call; for the purpose of example, we’ll use operator.mul, though a more real-world example might be a network call or a particular call in your application.
>>> import operator
>>> def chooseMul(job):
... return job.callable == operator.mul
...
You might want something more sophisticated, such as preferring operator.mul, but if one is not in the queue, it will take any; or doing any other priority variations. To do this, you’ll want to write your own agent–possibly inheriting from the provided one and overriding _choose.
Let’s set up another agent, in addition to the default one, that has the chooseMul policy.
>>> agent2 = dispatcher_agents['mul'] = zc.async.agent.Agent(chooseMul)
Another characteristic of agents is that they specify how many jobs they should pick at a time. The dispatcher actually adjusts the size of the ZODB connection pool to accommodate its agents’ size. The default is 3.
>>> agent.size
3
>>> agent2.size
3
We can change that at creation or later.
Finally, it’s worth noting that agents contain the jobs that are currently worked on by the dispatcher, on their behalf; and have a completed collection of the more recent completed jobs, beginning with the most recently completed job.
Logs are sent to the zc.async.events log for big events, like startup and shutdown, and errors. Poll and job logs are sent to zc.async.trace. Configure the standard Python logging module as usual to send these logs where you need. Be sure to auto-rotate the trace logs.
The package supports monitoring using zc.monitor. Using this package includes only a very few additional dependencies: zc.monitor, simplejson, and zc.ngi. An example of setting it up without Zope 3 is in the end of Quickstart with virtualenv. If you would like to use it, see that document, monitor.txt in the package, and our next section: Configuration with Zope 3.
Otherwise, if you want to roll your own monitoring, glance at monitor.py and monitordb.py–you’ll see that you should be able to reuse most of the heavy lifting, so it should be pretty easy to hook up the basic data another way.
>>> reactor.stop()
Footnotes
| [1] | More specifically, as of this writing, these are the minimal egg dependencies (including indirect dependencies):
The next section, Configuration with Zope 3, still tries to limit dependencies–we only rely on additional packages zc.z3monitor, simplejson, and zope.app.appsetup ourselves–but as of this writing zope.app.appsetup ends up dragging in a large chunk of zope.app.* packages. Hopefully that will be refactored in Zope itself, and our full Zope 3 configuration can benefit from the reduced indirect dependencies. |

I created a stream called "Is there code for X?". Can other people see it? Is it a good idea? I was thinking it could serve as a kind of a log of what people are searching for and help in creating keyword searchable documentation. Whenever you search for something and don't immediately find it, just create a topic in the stream.
And of course when you do find it, write down where you found it in the topic.

Akan names are derived from Ghanian culture. Frequently in Ghana, children are given their first name as a 'day name' which corresponds to the day in the week they were born.The intention of this web application is to take a user's birthday and calculate the day of the week they were born and then depending on their gender outputs their Akan Name.
Below is how the names are given:

Hi @Mario Carneiro, @Keeley Hoek and I are having some "fun" profiling rewrite_search
, and discovered that all the arithmetic is slow.
don't generate proofs during the search
We're going to experiment to see if typeclass resolution is partly to blame, but I'm also wondering if you have a sense of whether it's better to use nat
or int
.
how are you proving things?
Maybe Keeley can tell me that nat
won't actually do for our purposes.
Nope, everything is in meta land.
oh --- sorry, it's not that part that is slow
it is the edit distance calculations that are slow
so this has nothing to do with proofs
they should both be pretty fast
We could use nat
I think
I just have to find all the typeclass names I think
for numbers less than 2^30 or so it's just using the C++ addition which should be super fast
ok, all our numbers should be small enough, I think
do you have any idea why min
could be (relatively speaking) slow?
there is a lot of overhead for VM stuff but no more than anything else
You can look at the code generated for a definition using set_option trace.compiler.optimize_bytecode true
oooh...
If you inline the definition of min
it's almost as fast as it possibly could be
if you don't inline there is possible inefficiency in creating and destroying the nat.decidable_linear_ordered_semiring
but I don't know how significant it is
(And by inline I mean attribute [inline] min
)
ooooh
can you inline instances?
like where they are used
you don't want to inline instances, you want to inline projections. My experiments with min
on nat
show exactly the kind of simplification you would want
Just for the record: we ended up getting a factor-of-three speedup by inlining a bunch of important things in the hotpath, and eliminating some pesky table lookups in favor of using more memory---and parallelisation is to come!
finally someone more clever than me is using a more clever approach to speed up things! :D
@Keeley Hoek would you have any insight as to how I could speed up this without doing what I did?
Unfortunately not without contriving a tactic kenny
---but I must get to bed!
:O the string @mv_polynomial σ α (@comm_ring.to_comm_semiring α _inst_3)
appears 31 times!
But its definitely something to think about
(@comm_ring.to_comm_semiring α _inst_3)
67 times!
Can you think of a general way to hint about this kind of stuff?
Maybe you could say "use comm_ring.to_comm_semiring
everywhere you can first"
To some tactic
I don't write tactics...
:D
It's on the list, then!

All replicated applications are first transactional applications. This means that you have the standard data guarantee issues to consider, all of which have to do with how durable and consistent you want your data to be. Of course, considerations of this nature also play a role in your application's performance. These issues are even more important for replicated applications because replication adds additional dimensions to them.
Notably, in a replicated application you must decide how durable your data is, by deciding how careful the Master will be to make sure a data write has been written to disk on its various Replica nodes before completing the transaction.
Consistency also adds an additional dimension in a replicated application, because now you must decide how consistent the various nodes in the replication group will be relative to the Master at any given time. If no writes are being performed on the Master, all Replicas will eventually catch up to the Master and so be completely consistent with it. But for most HA applications, writes are occurring on the Master, and so it is possible for some number of your Replicas to lag behind the Master. What you have to decide, then, is how sensitive your application is to this kind of temporary inconsistency.
Note that your consistency requirements can be gated by your durability requirements. Durability, in turn, can be gated by any concerns you might have on write throughput. At the same time, your consistency requirement can have an affect on the read performance of your Replicas. It is therefore a mistake to think about any one of these requirements in the absence of the others.
One of the reasons you might be writing a replicated application is to achieve a higher durability guarantee than you can get with a traditional transactional application.  For this class of application, the strongest durability guarantee you can have is to use synchronous commits (the commit does not complete until the data is written to disk), coupled with very frequent backups of your environment.
The problem with a stand-alone application in which you are seeking a very high durability guarantee is that your write throughput will suffer. Synchronous commits require disk writes, and disk I/O is one of the most expensive operations you can ask a database to perform.
In order to increase write throughput in your transactional application, you may decide to use asynchronous commits that do not require the disk I/O to complete before the transaction commit completes. The problem with this is that your application can potentially crash before a transaction has been completely written to disk. This represents a loss of data, which is to say the data is not durable.
Replication can help with your data durability in a couple of ways. Most importantly, replication allows you to commit to the network. This means that when your Master commits a transaction, the results of that commit are sent to one or more nodes available over the network. Consequently, multiple disks, disk controllers, power supplies, and CPUs are used to ensure the data modification makes it to stable storage.
Usually JE makes the commit operation on the Master wait until it receives acknowledgements from some number of electable nodes before returning from the operation. However, if you want to increase write throughput, you can configure your Master to proceed without acknowledgements, and so return immediately from the commit operation (once the commit operation has met the local durability requirement). The price that you pay for this is a reduced durability guarantee. How reduced the guarantee is, is a function of the number of electable nodes in your replication group (the more you have, the higher your durability guarantee is) and the quality and stability of your network.
Alternatively, you can obtain an extremely high durability guarantee by configuring the Master to wait for all electable nodes to acknowledge a commit operation before returning from the operation. The price you pay for this very high guarantee is greatly reduced write throughput.
For information on configuring and managing durability guarantees for your replicated application, see Managing Durability.
Data consistency means that the data you thought you wrote to your environment is in fact written to your environment. It also means that you will never find partial records written to your environment.
In a replicated application, consistency also means that data which is available on the Master is also available on the Replicas.
A simple transactional application offers consistency guarantees that are enforced when you commit a transaction. Your replicated application also offers this consistency guarantee (because it is also a transactional application). For this reason, the environment on the Master is always absolutely consistent. But beyond that, you need to manage consistency for data across all the nodes in your replication group.
When you commit a transaction on the Master, your Replica nodes may or may not have the data changes performed by that transaction at the end of the commit. Whether they do depends on how high a durability guarantee you implemented for your Master (see the previous section). If, for example, you configured your Master to require acknowledgements from all electable nodes before returning from the commit, then the data will be consistently available across all of those nodes in the replication group, although not necessarily by secondary nodes. However, if you configured the Master such that no acknowledgements are necessary, then your data is probably not consistent across the replication group.
To ensure that read transactions on the Replicas see a sufficiently consistent view of the environment, you can set a consistency policy for each transaction. This policy describes how current the Replica must be before a transaction can be initiated on it. If the Replica is not current enough, the start of the transaction is delayed until the Replica has caught up.
There are two possible consistency policies. First, there is a time-based policy that describes how far back in time the Replica is allowed to lag behind the Master. Secondly, you can use a commit-based consistency policy that is based on the commit of a specified transaction. This policy is used to ensure the Replica is at least current enough to have the changes made by a specific transaction, and by all transactions committed prior to the specified transaction. The start of a transaction on a Replica can be delayed until the Replica can meet the consistency policy defined for that transaction.
This means that a stringent consistency policy can affect your Replica's read throughput. Transactions, even read-only transactions, cannot begin until the Replica is consistent enough. So if you have a Replica that has lagged far behind the Master, and which is having trouble catching up due to network latency or other issues, then read requests may stall, and perhaps even time out, which will affect the latency of your Replica's read requests, and perhaps even its overall availability for read requests. For this reason, give careful consideration to how well you want your Replica to perform on reads, versus how consistent you want the Replica to be with other nodes in the replication group.
For more information on managing consistency in your replicated application, see Managing Consistency.
