FOOMATIC-PPD-OPTIONS(1) FOOMATIC-PPD-OPTIONS(1) NAME foomatic-ppd-options - show the PPD options SYNOPSIS foomatic-ppd-options [-d=debuglevel] [ ppdfiles ] DESCRIPTION The foomatic-ppd-options program reads the specified PPD files or stdin and decodes the PPD file to produce a list of options. This is really just a text based version of other print configuration tools. The output format consists of a set of lines, each starting with a key‐ word, followed by a set of options and the default value. For example: makemodel = Tektronix Phaser 350 Foomatic/Postscript (recommended) name=PageSize; default=Letter; options=Letter (US Letter), \ A4 (A4), 11x17 (11x17), A3 (A3), A5 (A5), B5 (B5 \(JIS\)),... name=PageRegion; default=Letter; options=Letter (US Letter), A4 (A4), ... Each option starts with the name tag, followed by a default value (if any), followed by the set of options and a comment describing them. Punctuation in the comment is escaped. Options -ddebuglevel Set the debug level. 0 disables debug messages. [ files ] The list of PPD files to read for options. A '-' causes STDIN to be read. EXIT STATUS foomatic-ppd-options exits with a 0 status if successful, and nonzero if an error. An error message is also printed on standard error (STDERR).

Welcome to the output distribution page.
The distribution of the requested outputs are shown in this page. To visualise the 1-D histograms with a different number of bins, change the value of the first box and press the Intro key of the keyboard.
The second box defines the number of bins of the joint-PDF,
and the length of the discretised domain for the analysis.
Keep in mind that the time to complete the computation of the Fisher information matrix is proportional to
the number of bins to the power of the number of requested outputs.
For more than four outputs requested, six bins are enough to estimate the Fisher information matrix
with a reasonable degree of accuracy in a relatively short time
(about one minute, for all of the six outputs and 1000 Monte Carlo simulations.)

OrmAuth Usage
As said in the introduction of the Auth package, an authentication system comes with
three different drivers, each dealing with a part of the system:
The Ormauth login driver provides the logic for creating, updating, deleting and validating user accounts
stored in a local database table, for getting information about those accounts, for generating or resetting
passwords, and for login and logout operations (creating a user session).
The Ormauth group driver stores its group definitions in the database, and accesses it through ORM. It provides the logic
for checking if a user is a member of a group, and for retrieving group information, or the roles defined to to a group.
The Ormauth acl driver is role driven, and stores its acl definitions in the database, and accesses it through ORM.
It provides the logic for checking if a user has access to a named ACL.
Static vs Dynamic
As explained in the introduction, the Auth package provides a static interface to most of the method available, providing you
only a single driver set. These methods will be defined below as "Static: Yes". All methods are also accessable via chaining on the
Auth instance or an Auth driver instance object, including the ones marked as static.
Class methods
validate_user($username_or_email = '', $password = '')
The validate_user method validates user credentials. This method supports both email address and username as valid credential.
| Static |
Yes |
| Parameters |
| Param |
Default |
Description |
| $username_or_email |
''
|
Either the users username or email address |
| $password |
''
|
The users password |
|
| Returns |
mixed. false if the user didn't pass validation, or an instance of \Model\Auth_User with the users information if the credentials were valid. |
| Example |
// validate the passed username and password
if ($user = Auth::validate_user($name, $pass))
{
// $name and $pass validated, print the username
echo $user->username;
}
|
This method only validates if a given combination of username and password is correct. It does NOT log the user in!
login($username_or_email = '', $password = '')
The login method performs a login request. If a parameter is not given, it will attempt to
retrieve it from posted data, used the form fieldnames configured in the ormauth.php configuration file.
Internally it calls the validate_user() method to validate the request before attempting a login.
| Static |
Yes |
| Parameters |
| Param |
Default |
Description |
| $username_or_email |
''
|
Either the users username or email address |
| $password |
''
|
The users password |
|
| Returns |
boolean. returns true if the login was succesful, false otherwise. |
| Example |
// perform a login
if (Auth::login($name, $pass))
{
// the user is succesfully logged in
}
|
After a succesful login, the 'username' and the current 'login_hash' will be available as a session variable.
check()
The check method checks if a logged-in user is present.
| Static |
Yes |
| Parameters |
None
|
| Returns |
boolean. returns true if a logged-in user is present, false otherwise. |
| Example |
// login if we're not logged-in
if ( ! Auth::check())
{
Response::redirect('/login');
}
|
force_login($user_id = '')
The force_login method performs a forced login request. You can use this for an automated login, when you know
the users id, but you don't know the password. This can be used for example to implement a "remember me" feature.
| Static |
Yes |
| Parameters |
| Param |
Default |
Description |
| $user_id |
required |
The id of the user you want to login, or a valid instance of \Model\Auth_User |
|
| Returns |
boolean. returns true if the login was succesful, false otherwise. |
| Example |
// perform a forced login for user 12121
if (Auth::force_login(12121))
{
// the user is succesfully logged in. Any previously logged-in user will be logged out!
}
// perform a forced login for user object 12121
$user = \Model\Auth_User::find(12121);
if (Auth::force_login($user))
{
// the user is succesfully logged in. Any previously logged-in user will be logged out!
}
|
logout()
The logout method logs out the current logged-in user.
| Static |
Yes |
| Parameters |
None
|
| Returns |
boolean. returns true if the logout was succesful, false otherwise. |
| Example |
// perform a logout
Auth::logout();
|
If you have enabled guest user support, the guest user will be setup after a succesful logout.
create_user($username, $password, $email, $group = 1, Array $profile_fields = array())
The create_user allows method you to create a new user record in the users table.
| Static |
Yes |
| Parameters |
| Param |
Default |
Description |
| $username |
required |
The name of the user you want to create |
| $password |
required |
The password you want to assign to the user |
| $email |
required |
The email address of the user you want to create |
| $group |
1 |
The group you want to assign this user to. By default, the user is assigned to group 1. |
| $profile_fields |
array()
|
Any additional user metadata you want to assign to this user |
|
| Throws |
SimpleUserUpdateException |
| Returns |
mixed. returns the id of the user record created, or false if the creation failed. |
| Example |
// create a new user
Auth::create_user(
'anewuser',
'thisismysecretpassword',
<EMAIL_ADDRESS>1,
array(
'fullname' => 'A. New User',
)
);
|
The $profile_fields parameter is defined for API compatibility with Simpleauth. The field in the user
table is not used, any metadata passed is stored in the metadata table.
update_user($values, $username = null)
The update_user method allows you to update values in the user record,
either for a named user, or for the current logged-in user.
| Static |
Yes |
| Parameters |
| Param |
Default |
Description |
| $values |
array()
|
Associative array with column name / value pairs for the columns or profile fields you want to update. |
| $username |
null
|
The name of the user you want to update |
|
| Throws |
SimpleUserUpdateException |
| Returns |
boolean. returns true if columns were updated, or false if no columns were affected. |
| Example |
// update the data for the current user
Auth::update_user(
array(
'email' =><EMAIL_ADDRESS>// set a new email address
'password' => 'thisismynewpassword', // set a new password
'old_password' => 'thisismysecretpassword', // to do so, give the current one!
'phone' => '+1<PHONE_NUMBER>', // and add the phone number to the metadata
)
);
|
This method is primary provided to allow the user to do profile updates. And as a security measure, it will not allow you
to change the username, and if you want to change the password, you have to pass the current password in $values as "old_password".
change_password($old_password, $new_password, $username = null)
The change_password method allows you to change a users password.
| Static |
Yes |
| Parameters |
| Param |
Default |
Description |
| $old_password |
required |
The users current password |
| $new_password |
required |
The users new password |
| $username |
null
|
The name of the user of whom you want to change the password |
|
| Throws |
SimpleUserUpdateException |
| Returns |
boolean. returns true if the password was changed, or false if the old password was incorrect. |
| Example |
// reset the password for the current user
Auth::change_password('thisismynewpassword','thisismysecretpassword');
|
This method is provided to allow the user to change his password. And as a security measure, you have to
pass the current password in "old_password".
reset_password($username)
The reset_password method allows you to assign a new random password to a user.
| Static |
Yes |
| Parameters |
| Param |
Default |
Description |
| $username |
required |
The name of the user for whom you want to reset the password |
|
| Throws |
SimpleUserUpdateException |
| Returns |
string, the generated random password. |
| Example |
// reset the password for the current user
$new_password = Auth::reset_password('thisusername');
|
delete_user($username)
The delete_user method allows you to delete a user account.
| Static |
Yes |
| Parameters |
| Param |
Default |
Description |
| $username |
required |
The name of the user account you want to delete |
|
| Throws |
SimpleUserUpdateException |
| Returns |
boolean. returns true if the user account was deleted, or false if it failed (because the username did not exist). |
| Example |
// delete the user
Auth::delete_user('thisusername');
|
This will delete all metadata too, using ORM's cascade_delete feature.
create_login_hash()
The create_login_hash method generates a new login hash for the currently logged-in user.
| Static |
Yes |
| Parameters |
None
|
| Returns |
string, the generated login hash. |
| Example |
// generate a new random hash
Auth::create_login_hash();
|
This method is normally used when a user logs in, but you can use this as an extra security measure by rotating
the hash regularly for logged-in users.
Note that login hash protection is not used when multiple logins is enabled!
get($field, $default = null)
The get method is a generic getter for user properties, either from the user record, or from the metadata.
| Static |
Yes |
| Parameters |
| Param |
Default |
Description |
| $field |
required |
The name of the property you want the value of |
| $default |
null
|
The value to return is the property is not set |
|
| Returns |
mixed. |
| Example |
// get the user creation date
$created_at = Auth::get('created_at');
|
get_user_id()
The get_user_id method returns an array structure containing the drivers id value, and the id of
the currently logged-in user. It uses this structure because you can have multiple login drivers active, each can have
a different id for the currently logged-in user.
| Static |
Yes |
| Parameters |
None
|
| Returns |
mixed. returns a numeric array in the form array([0]=>driver_id, [1]=>user_id) if a user is logged in, or false otherwise. |
| Example |
// get all login id information
$id_info = Auth::get_user_id();
// print driver and id info
if ($id_info)
{
foreach ($id_info as $info)
{
echo 'Driver: ',$info[0],' with ID ',$info[1],'
';
}
}
else
{
echo 'Nobody is logged in!';
}
// if you only use one driver, you can also do
list($driver, $userid) = Auth::get_user_id();
// or this if you only need the userid
list(, $userid) = Auth::get_user_id();
|
If guest user support is enabled, you will never get false returned, because the method will return the user id of the guest user.
get_groups()
The get_groups method returns the ORM user group object assigned to the currently logged-in user.
| Static |
Yes |
| Parameters |
None
|
| Returns |
mixed. Returns an array in the form array(array(driver, group-object)) if a user is logged in, or false otherwise.
|
Example |
// get all group id information
$id_info = Auth::get_groups();
// print driver and id info
if ($id_info)
{
foreach ($id_info as $info)
{
echo 'Driver: ',$info[0],' with group ID ',$info[1]->id,'
';
}
}
else
{
echo 'Nobody is logged in!';
}
// if you only use one driver, you can also do
list($driver, $group) = Auth::get_groups();
echo 'Driver: ',$driver,' with group ID ',$group->id,'
';
|
If guest user support is enabled, you will never get false returned, because the method will return the group information of the guest user.
get_email()
The get_email method returns the email address assigned to the currently logged-in user.
| Static |
Yes |
| Parameters |
None
|
| Returns |
mixed. returns an email address if a user is logged in, or false if there is no user logged-in. |
| Example |
// get the current users email address
$email = Auth::get_email();
// note that there is a difference between false and empty:
if ($email === false)
{
// nobody logged in
}
if (empty($email))
{
// a user is logged in, but doesn't have an email address
}
|
If guest user support is enabled, you will never get false returned, because the method will return the email address of the guest user.
get_screen_name()
The get_screen_name method returns the screen- or display name of the currently logged-in user.
| Static |
Yes |
| Parameters |
None
|
| Returns |
mixed. returns a string containing the name, or false if there is no user logged-in. |
| Example |
// get the current users screen name
$name = Auth::get_screen_name();
// name is required, so if not present it means nobody is logged in
if (empty($name))
{
// nobody logged in
}
|
If guest user support is enabled, you will never get false returned, because the method will return the user name of the guest user.
get_profile_fields($field = null, $default = null)
The get_profile_fields method returns one or all stored profile fields for the logged-in user.

mixed |
| Example |
// get all profile fields defined
$profile = Auth::get_profile_fields();
// get a specific profile fields defined
$fullname = Auth::get_profile_fields('fullname', 'Unknown');
// will return null, as username is not part of the metadata
$fullname = Auth::get_profile_fields('username', 'Unknown username');

| Returns |
boolean. true if the user is member of the group, or false if not. |
| Example |
// Check if the current user is an administrator
if (Auth::member(100))
{

}
|
groups($driver = null)
The groups method allows you to fetch all defined groups, or all defined groups in a specific driver.

Yes |
| Parameters |
| Param |
Default |
Description |
| $driver |
null
|
The name of the group driver you want to get groups of |

| Returns |
array of \Model\Auth_Group objects. If the group driver does not exist or no groups are defined, an empty array is returned. |
| Example |
// Get all defined groups (for all loaded group drivers)
$groups = Auth::groups();
// Get all the groups from the default group driver
$groups = Auth::group()->groups();
// Get all the groups from a specific driver
$groups = Auth::group('Ormgroup')->groups();
|
You need to call this method on the Auth group drivers instance if you want groups defined by a specific driver.
If you use multiple drivers, this method only works reliably if the group id's are unique over all drivers!
roles($driver = null)
The roles method allows you to fetch all defined roles, or all defined roles in a specific driver.

| Example |
// Get all defined roles (for all loaded acl drivers)
$roles = Auth::roles();
// Get all the roles from the default acl driver
$roles = Auth::acl()->roles();
// Get all the roles from a specific driver
$roles = Auth::acl('Ormacl')->roles();
|
You need to call this method on the Auth acl drivers instance if you want groups defined by a specific driver.
If you use multiple drivers, this method only works reliably if the role id's are unique over all drivers!
get_name($group = null)
The get_name method allows you to fetch the name of a specific group. If no group is given, it will return the name
of the group of the current logged-in user.

// Get all the name for the group of the current logged-in user
$name = Auth::group()->get_name();
// Get the name of a specific group from a specific driver
$name = Auth::group('Ormgroup')->get_name(100); // returns 'Administrators'
|
If you use multiple drivers, this method only works reliably if the group id's are unique over all drivers!
has_access($condition)
The has_access method allows you to check if the current logged-in user has access to a specific location with specific rights.

{
// yes, the user has access to both blog posts and blog comments
}
// you can also specify the permissions to check as an array
if (Auth::has_access(array('blog' => array('post'), 'comments' => array('post')))
{
// yes, the user has access to read both blogs and comments posts

| Parameters |
| Param |
Default |
Description |
| $user_id |
null
|
The id of the user to be remembered |

// process the login form POST, and set the remember-me cookie if needed
if (\Input::method() == 'POST')
{
// check the credentials.
if (\Auth::instance()->login(\Input::param('username'), \Input::param('password')))
{
// does the user want to be remembered?
if (\Input::param('rememberme', false))
{
// create the remember-me cookie
\Auth::remember_me();
}
else
{
// delete the remember-me cookie if present
\Auth::dont_remember_me();
}
// logged in, go the homepage
\Response::redirect('/');
}
else
{
// login failed, show an error message
$data['username'] = \Input::param('username');

Tuning the Teleprocessing EnvironmentTuning your teleprocessing environment is essential to ensure that your online transactions are running in an optimal fashion. DB2 can use any of the three teleprocessors supplied by IBM: CICS, IMS/TM, and TSO. The tuning advice is different for each. In this section, I do not provide in-depth tuning advice for your teleprocessing environments. An entire book could be devoted to the tuning of CICS, IMS/TM, and TSO. Your shop should ensure that the requisite level of tuning expertise is available. However, you should keep in mind several basic online tuning strategies. The following guidelines are applicable for each teleprocessing environment supported by DB2. Limit Time on the Transaction QueueTune to limit the time that transactions spend on the input queue and the output queue. This way, you can decrease overhead and increase response time. Design Online Programs for PerformanceEnsure that all the program design techniques presented in Chapter 18, "The Doors to DB2," are utilized. Store Frequently Used Data in MemoryPlace into memory as many heavily used resources as possible. For example, consider using data spaces for CICS tables. Make Critical Programs ResidentConsider making programs for heavily accessed transactions resident to reduce the I/O associated with loading the program. A resident program remains in memory after the first execution, thereby eliminating the overhead of loading it each time it is accessed. Buffer All Non-DB2 Data SetsEnsure that all access to non-DB2 data sets (such as VSAM or IMS) is buffered properly using the techniques |

This block has a vector of Boolean input signals u[nu] and a vector of (time varying) Integer expressions expr[nu]. The output signal y is set to expr[i], if i is the first element in the input vector u that is true. If all input signals are false, y is set to parameter "y_default" or the last value is kept, if use_pre_as_default = true.
// Conceptual equation (not valid Modelica) i = 'first element of u[:] that is true'; y = if i==0 then (if use_pre_as_default then pre(y) else y_default) else expr[i];
The input connector is a vector of Boolean input signals. When a connection line is drawn, the dimension of the input vector is enlarged by one and the connection is automatically connected to this new free index (thanks to the connectorSizing annotation).
The usage is demonstrated, e.g., in example Modelica.Blocks.Examples.IntegerNetwork1.


In case you have not yet noticed, Nyzo is a very different blockchain. With Nyzo, we did not attempt to produce an iterative improvement over previous blockchains. We attempted to produce a blockchain that addressed every major issue, both economic and technical, that we saw in previous blockchain systems.
Proof of diversity, the balance-list mechanism, and the radically democratic nature of Nyzo are the most obvious differences in Nyzo. However, the transaction-fee structure and the absence of mining are no less important than these other characteristics to whether Nyzo becomes a viable, sustainable digital currency. Nyzo is not mined, there are no mining rewards, and there was no premine. 100 million coins were generated in the Genesis block. Coin-generation transactions are not allowed outside the Genesis block, so no more coins will ever be generated in this blockchain.
In a mined cryptocurrency, the premine proportion is important. Every additional coin that is premined or instamined takes away from the proportional value of awards to miners, and more mining effort equates directly to a stronger blockchain. In our minds, a mined cryptocurrency with more than a 5% premine or any sort of ICO is unjustifiable. A bigger premine directly weakens the strength of the blockchain. A premine of more than a few percent drastically reduces the probability that mining rewards will be able to encourage sufficient mining activity to properly secure the blockchain relative to coin values.
This is not how Nyzo works.
In Nyzo, there is no mining, and there is a strict limit on the rate at which verifiers can be added to the cycle. This limit cannot be eliminated or changed, as it would weaken the proof system. Unlike a mined cryptocurrency where miners can be activated quickly to begin mining, this cannot happen in Nyzo. A halving or doubling of the wait list for joining Nyzo will have no immediate effect on the strength of the blockchain.
Verifiers are important to Nyzo, and the structure of Nyzo's proof system protects the interests of verifiers. In most cryptocurrencies, if mining suddenly becomes 10 times more profitable, then competition for mining rewards will also increase by a factor of 10. Existing miners will see little additional profit, and they may even be unable to compete against more powerful mining operations. With Nyzo, verifiers in the cycle are, by the definitions of the system, irreplaceable. If a verifier drops out of the cycle, the growth of the cycle represented by that verifier is lost forever to the blockchain. And as long as a verifier fulfills its obligations in helping to build the blockchain, it can stay in the cycle indefinitely.
In Nyzo, transaction fees are the only reward for verifying blocks. To get the system started, we put ∩20,000,000 into an account and pre-signed five years of transactions (with a sixth year of redundant transactions that are only in place in case earlier transactions are omitted). We never saved the private key for the account that holds the funds for these transactions, and we have since added code that protects the account from unauthorized transactions.
The ∩20,000,000 amount was not chosen as a complete solution for distributing coins. It was chosen to mimic organic transaction volume. In other words, Nyzo's goal is reaching an organic transaction volume that allows verifiers to be profitable from organic transaction volume alone. If Nyzo can reach such a level, it will be a perpetually sustainable system without the need for any additional seed transactions or other additional injection of coins. No devaluation of existing coins through issuance of new coins. No artificially low transaction fees subsidized by block rewards. No pre-programmed drop-offs in rewards that weaken the system. No games. Just a system that works really well for everyone involved, providing convenience to users and reasonable profits to the verifiers running the system. That's what we're trying to build here.
An increase in seed transactions now would give verifiers an unrealistic expectation for future earnings and would sacrifice long-term sustainability of the system for the sake of short-term profits for individuals involved in the system now.
To us, any action that increases the price of a cryptocurrency without providing long-term, sustainable value is unethical. This is why we refuse to burn coins. This is why we refused to rush to a poorly conceived plan for the remaining coins. This is why we refuse to advertise. This is why we do not have a Facebook page or Twitter account. This is why we have not made a single public announcement. This is why we have a utilitarian web site that communicates the information that it needs to communicate but probably scares off many people who might otherwise be interested in the project. This is why we have been willing to award large bounties for code issues.
We plan to remain anonymous. We are uninteresting people with relatively mundane lives, and we feel that public presences in the crypto world would be a distraction from our lives, our families, and the important technical aspects of this project. We want to focus on the technology of this project and the technology that this project may be able to contribute to the world. This has been our aim from the very beginning.
To this point in time, the Nyzo team has not sold any coins whatsoever: not from the block-1 accounts, not from our official Nyzo verifiers, not from our anonymous verifiers that we run for testing. We have been supporting this project with personal funds. In addition to infrastructure and legal expenses, we have collectively invested over 15,000 hours of planning and implementation in this project.
We will gain very little from the following plan if Nyzo is not successful moving forward. We want to help build a system that has a positive effect on the world, and we want to help build a system that is sustainable. We think Nyzo is going to fundamentally change how content is monetized on the internet, and we think that Nyzo is going to fundamentally change how blockchains are viewed by the world. If this does not happen, and if organic transactions do not increase dramatically, the plan will keep the vast majority of our funds locked and inaccessible to us for such a long time that they will be essentially valueless to us.
The block-1 distribution wallets currently contain ∩77,507,419.
∩30,507,419 will be transferred to a cycle-controlled account, address 0000...0002. After transaction fees, this account will contain ∩30,431,150. Transfers out of this account will require signatures of at least 75% of the current cycle, and transfers out of this account may be no more than ∩100,000 each.  This mechanism will effectively lock these coins, subject to trust in the cycle. And if you don't trust the cycle, you cannot trust the system.
To replenish the funds of the cycle account, 1% of organic transaction fees (0.0025% of organic transaction amounts) will automatically transfer to this account moving forward. This rule will apply to organic transactions only, not seed transactions. This will mean that verifiers' fees from organic transactions will be reduced to 99% of what they are now. At the current rate of organic transactions, this change would cost each verifier an average of less than ∩0.0001 per day. This fee will ensure that the cycle has a sustainable supply of funds for addressing shared expenses. This is not a developer fee. This is a fee coming from the cycle verifiers and going to a wallet that the cycle verifiers control.
We do want to emphasize that the trust placed in the cycle with the shared cycle account is significant, and we want to emphasize that the responsibility of this account needs to be taken seriously. This account will be expected to pay all bounties. These bounties will need to be paid quickly and at appropriate levels to encourage constructive behavior by those who find flaws in the system. Irresponsible or careless use of these funds will be detrimental to the credibility of Nyzo and will devalue the system.
This account will need to last perpetually to support cycle-funded initiatives and bounties. While we expect the balance of this account to drop over the next few years as organic transaction volume is building, we would hope that the account is left with a large reserve (∩20,000,000 or more) most of the time to provide a substantial buffer to address any needs that arise.
This account should be treated for what it is: a substantial asset to the system that should be managed with thoughtfulness and care.
After funding of the cycle account, ∩47,000,000 will be left in the distribution accounts. These funds will be locked with a threshold. The threshold will be stored in the balance list (threshold) along with the sum of all previous transactions out of distribution addresses (sum). The verifiers will keep all distribution addresses in memory. A standard (non-seed) transaction from a distribution address to any account other than the cycle address (0000...0002) will only be approved if the following is true of its value (transaction amount):
sum + transaction amount <= threshold
If such a transaction is approved, its amount is added to the sum. The sum and the threshold will both start at ∩0. This means that all block-1 distribution accounts will be effectively 100% locked when these changes are adopted by the cycle.
After this locking is put in place, all organic transaction fees will be added to the threshold. So, if a block has ∩0.5 in transaction fees, then the threshold will increase by ∩0.5 in that block. Also, for the first 2,000,000 blocks after the locking is put in place, an additional ∩0.10 per block will be added to the unlock amount. This will unlock an additional ∩200,000 over the course of 162 days to help cover some of our initial expenses. The transfer of ∩30,507,419 to the cycle account will unlock an additional ∩76,269, as it will provide an additional ∩76,269 in fees to the cycle.
Moving forward, unlocking of funds will be close to zero if organic transaction volume does not increase. Over the past 90 days, organic transaction fees have averaged less than ∩0.01 per block. At the current rate, the remaining funds would take over 1,200 years to fully unlock.
Our goal with Nyzo has always been creation of a sustainable, democratic, decentralized, fair blockchain that actually works for everyone involved. Tying the unlocking of funds to organic transaction volume provides assurance to verifiers and users of the system that remaining funds will unlock at a rate that is controlled and proportional to actual activity. This will ultimately provide a better outcome for verifiers than additional seed transactions ever could, as seed transactions must decrease over time as funds are depleted, and organic transactions can and should be sustainable indefinitely.
These remaining funds belong to the Nyzo team. We will use them as we choose to advance the project, and we will have no further discussions with the community regarding them. The gradual, activity-based unlocking of these funds will provide blockchain-enforced reassurance that the funds will not be released to the market at a disruptive rate.
For anyone concerned that organic transaction fees will grow at an exceptional rate and will unlock our funds unreasonably quickly, please think out that criticism so you can realize how unreasonable it is. This situation would be exceptionally good for the team and exceptionally good for all verifiers. Full unlocking of these funds will require ∩18,800,000,000 in organic transactions.
Account fees for all accounts containing ∩1 or greater will be eliminated. Account fees for accounts containing ∩0.999999 or less will be raised to µ100 per 500 blocks. This will allow small accounts to be removed from the balance list 100 times as fast while eliminating account fees entirely for most accounts in the system.
We are currently planning on having these changes integrated into the blockchain and ready for deployment at block 4,500,000, which is scheduled for processing on 2019-09-12 14:00:00.000 UTC. This change will introduce an incompatibility in the balance list, so all verifiers and sentinels will need to update before that block in order to continue tracking the blockchain. The update will be available no later than 2019-09-01 00:00:00.000 UTC.
If the changes are accepted by the cycle, the ∩30,507,419 cycle fund will be transferred to the cycle wallet after the changes are deployed. After this change and funding of the account, the cycle will be expected to pay all bounties, as the other wallets will be limited by the threshold from being able to initiate large transactions. The mechanisms for creating and approving cycle-signed transactions will be provided by the verifier and client software, but the decision-making process must be established by the community. We will have no control over how these funds are used, but we ask that the community considers the long-term sustainability of the system in all decisions. Specifically, we feel the need to note that using these funds to establish a new seed wallet while verification is still profitable, as it is now, would severely compromise the public's ability to trust the Nyzo cycle.
If the changes are not accepted by the cycle, we will continue awarding bounties from the funds we control. We will begin selling coins to offset some expenses, but we will apply the same unlocking rules outlined above to those sales. Instead of having the blockchain enforce the rules, we will enforce the unlocking rules ourselves, and decisions about administering the ∩30,507,419 bounty fund will remain ours to make. Whether or not these changes are accepted by the cycle, we will entertain no further discussions regarding these funds, and this statement is our final statement on the topic.
For anyone interested in exploring this matter further, we encourage the deployment of new Nyzo-based blockchains with different distribution and economic schemes. The release notes of version 492 provide a nice overview of how to start a Nyzo-based blockchain. Anyone who wants to write their own code to change the behavior of this blockchain is welcome to do so, also. We have gone to great lengths to explain, in our white paper and release notes, every important decision made in the development of Nyzo. The open nature of Nyzo means that our primary influence over the direction of Nyzo is our knowledge of how the system works, and we are working to reduce all other influence we have over the system.
As stated in the white paper, we will be shutting down all official Nyzo verifiers before the blockchain reaches an age of one year. A member of the community suggested that we continue to run them, and we felt this was an attractive option. We feel that positions in the cycle are valuable, and we expect them to be even more valuable over time. Also, well-maintained, well-operated verifiers make the cycle stronger. Functionally, the Nyzo verifiers have never been any different than any other verifiers in the cycle. They have always run the same code, and they have always been equal members of the Nyzo democracy. We had considered continuing to operate these verifiers at the discretion of the cycle, but we are concerned that such operation might be misinterpreted by observers as a form of centralization. We want to eliminate all concerns about centralization. We will continue to operate a small number of unofficial verifiers. These verifiers, like the Nyzo verifiers, will continue to run exactly the same code that we release to the community, and they will be equal members of the Nyzo democracy. The nyzo.co website will be unaffected. The setup instructions will be updated to help users find appropriate trusted entry points for connecting to the mesh.
The changes required to implement this plan are not substantial, but they will require substantial testing to ensure smooth deployment. These are the first Nyzo changes that will modify the structure of the balance lists. Due to this, the overall frequency of Nyzo updates will decrease until these changes are deployed.

Weekend Getaways: Soak up the sun and culture of Albuquerque
Albuquerque, New Mexico, has a lot to offer: natural beauty, rich culture, delicious food and activities you won’t find in other U.S. cities. But this sunny, charming destination can fly under the radar as tourists gravitate toward nearby Santa Fe. They’re missing out. After spending a long weekend in Albuquerque, I was completely smitten and eager to recommend this well-kept secret to Seattleites in search of a convenient, affordable getaway.
Averaging 280 sunny days per year, the Duke City might be the perfect antidote to the Seattle cloud cover. In early spring, daytime temperatures are typically in the mid-50s to 60s. (Pack extra layers for when it cools off after the sun goes down.) Affordable nonstop flights from Sea-Tac to Albuquerque clock in at around three hours.
From flamenco lessons to snowshoeing to eating all the chili-inspired dishes, here’s how to make the most of a long weekend in Albuquerque.
Where to stay: Built in 1939 by Conrad Hilton, Hotel Andaluz (hotelandaluz.com) is a charming boutique hotel located in downtown Albuquerque. Be sure to explore the artwork on the second level. Rotated quarterly, all of of the pieces are by local artists and available for purchase. Eat dinner at MÁS — Tapas y Vino (hotelandaluz.com/mas-tapas-y-vino/) at least once. The shared plates are delicious and you’ll definitely want to save room for dessert — I highly recommend asking the chef to roast s’mores at your table. A historical property that reopened in July, El Vado Motel (elvadoabq.com) originally opened its doors in 1937 and was one of the first motels on the famous Route 66. Don’t be dissuaded by the word “motel”; El Vado has been completely refurbished and the rooms are charming, clean and well-decorated. Grab a beer at El Vado Tap Room and chat with the friendly locals who frequent the bar — they’re more than happy to share tips and recommendations.
Local activities: Take in the sights of Albuquerque and eat some seriously delicious food on the Flavors of ABQ Bike Tour with Routes Bicycle Tours & Rentals (routesrentals.com). My favorite stops were Pop Fizz (pop-fizz.net), where I sampled ice-pop flavors including cucumber chili lime and mango red chili, and Sushi King, where I devoured about five New Mexico rolls.

Classical mechanics is a topic which has been taught intensively over several centuries. It is, with its many variants and ways of presenting the educational material, normally the first real physics course many of us meet and it lays the foundation for further physics studies. Many of the equations and ways of reasoning about the underlying laws of motion and pertinent forces, shape our approaches and understanding of the scientific method and discourse, as well as the way we develop our insights and deeper understanding about physical systems.
There is a wealth of well-tested (from both a physics point of view and a pedagogical standpoint) exercises and problems which can be solved analytically. However, many of these problems represent idealized and less realistic situations. The large majority of these problems are solved by paper and pencil and are traditionally aimed at what we normally refer to as continuous models from which we may find an analytical solution. As a consequence, when teaching mechanics, it implies that we can seldomly venture beyond an idealized case in order to develop our understandings and insights about the underlying forces and laws of motion.
On the other hand, numerical algorithms call for approximate discrete models and much of the development of methods for continuous models are nowadays being replaced by methods for discrete models in science and industry, simply because much larger classes of problems can be addressed with discrete models, often by simpler and more generic methodologies.
As we will see below, when properly scaling the equations at hand, discrete models open up for more advanced abstractions and the possibility to study real life systems, with the added bonus that we can explore and deepen our basic understanding of various physical systems
Analytical solutions are as important as before. In addition, such solutions provide us with invaluable benchmarks and tests for our discrete models. Such benchmarks, as we will see below, allow us to discuss possible sources of errors and their behaviors. And finally, since most of our models are based on various algorithms from numerical mathematics, we have a unique oppotunity to gain a deeper understanding of the mathematical approaches we are using.
With computing and data science as important elements in essentially all aspects of a modern society, we could then try to define Computing as solving scientific problems using all possible tools, including symbolic computing, computers and numerical algorithms, and analytical paper and pencil solutions. Computing provides us with the tools to develope our own understanding of the scientific method by enhancing algorithmic thinking.
The way we will teach this course reflects this definition of computing. The course contains both classical paper and pencil exercises as well as computational projects and exercises. The hope is that this will allow you to explore the physics of systems governed by the degrees of freedom of classical mechanics at a deeper level, and that these insights about the scientific method will help you to develop a better understanding of how the underlying forces and equations of motion and how they impact a given system. Furthermore, by introducing various numerical methods via computational projects and exercises, we aim at developing your competences and skills about these topics.
These competences will enable you to
The power of the scientific method lies in identifying a given problem as a special case of an abstract class of problems, identifying general solution methods for this class of problems, and applying a general method to the specific problem (applying means, in the case of computing, calculations by pen and paper, symbolic computing, or numerical computing by ready-made and/or self-written software). This generic view on problems and methods is particularly important for understanding how to apply available, generic software to solve a particular problem.
However, verification of algorithms and understanding their limitations requires much of the classical knowledge about continuous models.
Before we venture into a reminder on Python and mechanics relevant applications, let us briefly outline some of the abovementioned topics using an example many of you may have seen before in for example CMSE201. A simple algorithm for integration is the Trapezoidal rule. Integration of a function \( f(x) \) by the Trapezoidal Rule is given by following algorithm for an interval \( x \in [a,b] \) $$ \int_a^b(f(x) dx = \frac{1}{2}\left [f(a)+2f(a+h)+\dots+2f(b-h)+f(b)\right] +O(h^2), $$ where \( h \) is the so-called stepsize defined by the number of integration points \( N \) as \( h=(b-a)/(n) \). Python offers an extremely versatile programming environment, allowing for the inclusion of analytical studies in a numerical program. Here we show an example code with the trapezoidal rule. We use also SymPy to evaluate the exact value of the integral and compute the absolute error with respect to the numerically evaluated one of the integral \( \int_0^1 dx x^2 = 1/3 \). The following code for the trapezoidal rule allows you to plot the relative error by comparing with the exact result. By increasing to \( 10^8 \) points one arrives at a region where numerical errors start to accumulate.
from math import log10
import numpy as np
from sympy import Symbol, integrate
import matplotlib.pyplot as plt
# function for the trapezoidal rule
def Trapez(a,b,f,n):
h = (b-a)/float(n)
s = 0
x = a
for i in range(1,n,1):
x = x+h
s = s+ f(x)
s = 0.5*(f(a)+f(b)) +s
return h*s
# function to compute pi
def function(x):
return x*x
# define integration limits
a = 0.0; b = 1.0;
# find result from sympy
# define x as a symbol to be used by sympy
x = Symbol('x')
exact = integrate(function(x), (x, a, b))
# set up the arrays for plotting the relative error
n = np.zeros(9); y = np.zeros(9);
# find the relative error as function of integration points
for i in range(1, 8, 1):
npts = 10**i
result = Trapez(a,b,function,npts)
RelativeError = abs((exact-result)/exact)
n[i] = log10(npts); y[i] = log10(RelativeError);
plt.plot(n,y, 'ro')
plt.xlabel('n')
plt.ylabel('Relative error')
plt.show()
This example shows the potential of combining numerical algorithms with symbolic calculations, allowing us to
