A simple but integral aspect of Fabric is what is known as the “environment”: a Python dictionary subclass, which is used as a combination settings registry and shared inter-task data namespace.
The environment dict is currently implemented as a global singleton, fabric.state.env, and is included in fabric.api for convenience. Keys in env are sometimes referred to as “env variables”.
Most of Fabric’s behavior is controllable by modifying env variables, such as env.hosts (as seen in the tutorial). Other commonly-modified env vars include:
There are a number of other env variables; for the full list, see Full list of env vars at the bottom of this document.
In many situations, it’s useful to only temporarily modify env vars so that a given settings change only applies to a block of code. Fabric provides a settings context manager, which takes any number of key/value pairs and will use them to modify env within its wrapped block.
For example, there are many situations where setting warn_only (see below) is useful. To apply it to a few lines of code, use settings(warn_only=True), as seen in this simplified version of the contrib exists function:
from fabric.api import settings, run
def exists(path):
with settings(warn_only=True):
return run('test -e %s' % path)
See the Context Managers API documentation for details on settings and other, similar tools.
While it subclasses dict, Fabric’s env has been modified so that its values may be read/written by way of attribute access, as seen in some of the above material. In other words, env.host_string and env['host_string'] are functionally identical. We feel that attribute access can often save a bit of typing and makes the code more readable, so it’s the recommended way to interact with env.
The fact that it’s a dictionary can be useful in other ways, such as with Python’s dict-based string interpolation, which is especially handy if you need to insert multiple env vars into a single string. Using “normal” string interpolation might look like this:
print("Executing on %s as %s" % (env.host, env.user))
Using dict-style interpolation is more readable and slightly shorter:
print("Executing on %(host)s as %(user)s" % env)
Below is a list of all predefined (or defined by Fabric itself during execution) environment variables. While many of them may be manipulated directly, it’s often best to use context_managers, either generally via settings or via specific context managers such as cd.
Note that many of these may be set via fab‘s command-line switches – see fab options and arguments for details. Cross-references are provided where appropriate.
参考
Default: None
Fabric normally handles aborting by printing an error message to stderr and calling sys.exit(1). This setting allows you to override that behavior (which is what happens when env.abort_exception is None.)
Give it a callable which takes a string (the error message that would have been printed) and returns an exception instance. That exception object is then raised instead of SystemExit (which is what sys.exit does.)
Much of the time you’ll want to simply set this to an exception class, as those fit the above description perfectly (callable, take a string, return an exception instance.) E.g. env.abort_exception = MyExceptionClass.
Default: False
When True, Fabric will run in a non-interactive mode, calling abort anytime it would normally prompt the user for input (such as password prompts, “What host to connect to?” prompts, fabfile invocation of prompt, and so forth.) This allows users to ensure a Fabric session will always terminate cleanly instead of blocking on user input forever when unforeseen circumstances arise.
バージョン 1.1 で追加.
Default: None
Set by fab to the full host list for the currently executing command. For informational purposes only.
Default: True
When set to False, causes run/sudo to act as if they have been called with pty=False.
参考
バージョン 1.0 で追加.
Default False
When set to True, error output to the terminal is colored red and warnings are colored magenta to make them easier to see.
バージョン 1.7 で追加.
Default: True
Causes the SSH layer to merge a remote program’s stdout and stderr streams to avoid becoming meshed together when printed. See Combining stdout and stderr for details on why this is needed and what its effects are.
バージョン 1.0 で追加.
Default: None
Set by fab to the currently executing command name (e.g., when executed as $ fab task1 task2, env.command will be set to "task1" while task1 is executing, and then to "task2".) For informational purposes only.
Default: []
Modified by prefix, and prepended to commands executed by run/sudo.
バージョン 1.0 で追加.
Default: 1
Number of times Fabric will attempt to connect when connecting to a new server. For backwards compatibility reasons, it defaults to only one connection attempt.
バージョン 1.4 で追加.
Default: True
Deduplicate merged host lists so any given host string is only represented once (e.g. when using combinations of @hosts + @roles, or -H and -R.)
When set to False, this option relaxes the deduplication, allowing users who explicitly want to run a task multiple times on the same host (say, in parallel, though it works fine serially too) to do so.
バージョン 1.5 で追加.
Default: False
If True, the SSH layer will skip loading the user’s known-hosts file. Useful for avoiding exceptions in situations where a “known host” changing its host key is actually valid (e.g. cloud servers such as EC2.)
Default: False
If True, causes fab to close connections after each individual task execution, instead of at the end of the run. This helps prevent a lot of typically-unused network sessions from piling up and causing problems with limits on per-process open files, or network hardware.
ノート
When active, this setting will result in the disconnect messages appearing throughout your output, instead of at the end. This may be improved in future releases.
Default: []
Specifies a list of host strings to be skipped over during fab execution. Typically set via --exclude-hosts/-x.
バージョン 1.1 で追加.
Default: fabfile.py
Filename pattern which fab searches for when loading fabfiles. To indicate a specific file, use the full path to the file. Obviously, it doesn’t make sense to set this in a fabfile, but it may be specified in a .fabricrc file or on the command line.
Default: None
Enables SSH-driven gatewaying through the indicated host. The value should be a normal Fabric host string as used in e.g. env.host_string. When this is set, newly created connections will be set to route their SSH traffic through the remote SSH daemon to the final destination.
バージョン 1.5 で追加.
参考
Default: None
Defines the current user/host/port which Fabric will connect to when executing run, put and so forth. This is set by fab when iterating over a previously set host list, and may also be manually set when using Fabric as a library.
Default: False
If True, enables forwarding of your local SSH agent to the remote end.
バージョン 1.4 で追加.
Default: None
Set to the hostname part of env.host_string by fab. For informational purposes only.
Default: 0 (i.e. no keepalive)
An integer specifying an SSH keepalive interval to use; basically maps to the SSH config option ClientAliveInterval. Useful if you find connections are timing out due to meddlesome network hardware or what have you.
参考
バージョン 1.1 で追加.
Default: None
A string, or file-like object, containing an SSH key; used during connection authentication.
ノート
The most common method for using SSH keys is to set key_filename.
バージョン 1.7 で追加.
Default: None
May be a string or list of strings, referencing file paths to SSH key files to try when connecting. Passed through directly to the SSH layer. May be set/appended to with -i.
Default: False
Forces buffering by line instead of by character/byte, typically when running in parallel mode. May be activated via --linewise. This option is implied by env.parallel – even if linewise is False, if parallel is True then linewise behavior will occur.
バージョン 1.3 で追加.
A read-only value containing the local system username. This is the same value as user‘s initial value, but whereas user may be altered by CLI arguments, Python code or specific host strings, local_user will always contain the same value.
Default: False
If True, will tell the SSH layer not to seek out running SSH agents when using key-based authentication.
バージョン 0.9.1 で追加.
参考
Default: False
If True, will tell the SSH layer not to load any private key files from one’s $HOME/.ssh/ folder. (Key files explicitly loaded via fab -i will still be used, of course.)
バージョン 0.9.1 で追加.
参考
Default: False
When True, forces all tasks to run in parallel. Implies env.linewise.
バージョン 1.3 で追加.
Default: None
The default password used by the SSH layer when connecting to remote hosts, and/or when answering sudo prompts.
Default: {}
This dictionary is largely for internal use, and is filled automatically as a per-host-string password cache. Keys are full host strings and values are passwords (strings).
バージョン 1.0 で追加.
Default: ''
Used to set the $PATH shell environment variable when executing commands in run/sudo/local. It is recommended to use the path context manager for managing this value instead of setting it directly.
バージョン 1.0 で追加.
Default: 0
Sets the number of concurrent processes to use when executing tasks in parallel.
バージョン 1.3 で追加.
Default: {}
The prompts dictionary allows users to control interactive prompts. If a key in the dictionary is found in a command’s standard output stream, Fabric will automatically answer with the corresponding dictionary value.
バージョン 1.9 で追加.
Default: None
Set to the port part of env.host_string by fab when iterating over a host list. May also be used to specify a default port.
Default: None
Set by fab with the path to the fabfile it has loaded up, if it got that far. For informational purposes only.
Default: None
Controls whether Ctrl-C triggers an interrupt remotely or is captured locally, as follows:
バージョン 1.6 で追加.
Default: False
If True, the SSH layer will raise an exception when connecting to hosts not listed in the user’s known-hosts file.
Default: None
If set, should be the path to a known_hosts file. The SSH layer will read this file before reading the user’s known-hosts file.
参考
Default: /bin/bash -l -c
Value used as shell wrapper when executing commands with e.g. run. Must be able to exist in the form <env.shell> "<command goes here>" – e.g. the default uses Bash’s -c option which takes a command string as its value.
Default: False
If True, causes fab (or non-fab use of execute) to skip over hosts it can’t connect to.
バージョン 1.4 で追加.
Default: $HOME/.ssh/config
Allows specification of an alternate SSH configuration file path.
バージョン 1.4 で追加.
Default: [0]
Return codes in this list are used to determine whether calls to run/sudo/sudo are considered successful.
バージョン 1.6 で追加.
Default: "sudo -S -p '%(sudo_prompt)s' " % env
The actual sudo command prefixed onto sudo calls’ command strings. Users who do not have sudo on their default remote $PATH, or who need to make other changes (such as removing the -p when passwordless sudo is in effect) may find changing this useful.
参考
The sudo operation; env.sudo_prompt
Default: "sudo password:"
Passed to the sudo program on remote systems so that Fabric may correctly identify its password prompt.
参考
The sudo operation; env.sudo_prefix
Default: None
Used as a fallback value for sudo‘s user argument if none is given. Useful in combination with settings.
参考
Default: []
Set by fab to the full tasks list to be executed for the currently executing command. For informational purposes only.
Default: True
Global setting which acts like the use_shell argument to run/sudo: if it is set to False, operations will not wrap executed commands in env.shell.
Default: False
Set to True to cause Fabric to load your local SSH config file.
バージョン 1.4 で追加.
Default: User’s local username
The username used by the SSH layer when connecting to remote hosts. May be set globally, and will be used when not otherwise explicitly set in host strings. However, when explicitly given in such a manner, this variable will be temporarily overwritten with the current value – i.e. it will always display the user currently being connected as.
To illustrate this, a fabfile:
from fabric.api import env, run
env.user = 'implicit_user'
env.hosts = ['host1', 'explicit_user@host2', 'host3']
def print_user():
with hide('running'):
run('echo "%(user)s"' % env)
and its use:
$ fab print_user
[host1] out: implicit_user
[explicit_user@host2] out: explicit_user
[host3] out: implicit_user
Done.
Disconnecting from host1... done.
Disconnecting from host2... done.
Disconnecting from host3... done.
As you can see, during execution on host2, env.user was set to "explicit_user", but was restored to its previous value ("implicit_user") afterwards.
ノート
env.user is currently somewhat confusing (it’s used for configuration and informational purposes) so expect this to change in the future – the informational aspect will likely be broken out into a separate env variable.
Default: current Fabric version string
Mostly for informational purposes. Modification is not recommended, but probably won’t break anything either.

When to use authentication
Authentication lets users verify who they are.
Most one-time services won't need to authenticate their users. When a service does need to verify a user’s identity, it needs to balance ease of access with keeping a service and its user data secure. You should think about this early on when designing your service.
You might want to authenticate users if:
- your service allows users to save and complete a transaction at another time
- a user can check the status of a transaction
- a user will use a service multiple times
Authentication examples
You can authenticate users using reference numbers, personal details, codes sent in SMS and emails, and using GOV.UK Verify. Don’t use National Insurance numbers to verify a user’s identity. Further guidance on National Insurance numbers and fraud can be found in the service manual.
You should consult a Home Office security specialist as they can advise you on the type of authentication that’s right for your service.
Example - authentication using a reference number
Authentication using a reference number
A reference number is a simple way to let users access a service. For example when a user saves progress and needs to return to complete a service.
Example - knowledge based authentication
Knowledge based authentication
Use knowledge based authentication when you need to confirm a users identity.
Example - two-factor authentication
Two-factor authentication
Two-factor authentication can be used when a service stores user data and allows users to access it. Two-factor helps protect the user and the service. There are three types of authentication: something a user knows (password, pin), something a user has (phone, fob), and a biometric like a fingerprint or voice.
Authentication is not the same as identity assurance
Identity assurance confirms the true identity of a user. The checks are usually done before confirming a users suitability for something. Identity assurance can consist of:
- confirming the user is a human
- confirming the validaty of information and documents
- fraud checks
- checking for warnings about a user
User accounts
User accounts are a form of authentication that you should try to avoid. Services should be public facing and not start behind a user log in. This is essential for users searching for the government service they need. Making users create accounts when not needed:
- creates a barrier for users and can reduce completion rates
- forces users to keep track of more logins then neccesary
- burdens teams with databases that are difficult to build and maintain
- increases the amount of redundant databases - which is expensive and a security risk
Only make users create an account if:
- users access a service frequently
- users need it - don't force them to create an account until necessary
- a service needs to audit user behaviour
Get in touch
If you’ve got a question or suggestion share it on Slack #interaction-designers channel or on GitHub.


Do you really want to reset your transfer skills?
You must use all your Holy Pomanders in order to use this service. After all, 10 million adena is a huge sum of money. Use the rest of your pomanders, then try your request again.
Do not fret. I will make sure that all of the Holy Pomanders you used are returned to you cleansed of any impurities.


ABSTRACT
Shlyun N.V., Bilobrytska O.I. Singularly perturbed problems of thermo-mechanics of layered road coatings. Visnyk National Transport University. Series «Technical sciences». Scientific and Technical Collection. - Kyiv: National Transport University, 2020. - Issue 1 (46).
The problem of singular perturbation of the equations of elastic bending of layered pavements and thermal conductivity is discussed. It is shown that the complexity of solving these equations significantly exceeds the complexity of singularly perturbed equations known in the scientific literature. First, this is due to the fact that in the problems of road construction, the mechanics of elastic bending are described by the partial differential equations, and the integration domain reaches large dimensions.
The problem of thermal deformation of the pavement and distribution in its array of temperature, displacement, and stress fields is also considered. It is proved that thesolution of the problemof thermal conductivity has the appearance of a boundary effect, localized in the elements of the coating adjacent to its free surface.Also is noted that high-gradient temperature distribution deep in the soil leads to large values of normal and tangential stresses that provoke cracking and delamination of the upper layers of the coating. They are confirmed by the results of computer simulation.
KEYWORDS: SINGULARLY PERTURBED PROBLEM, LAYERED ROAD COVERING, TEMPERATURE FIELD, TRANSPORT LOAD, STRESS FIELD, THERMAL STRAIN STATE.

In this experiment you will interact with {{ Constants.others }} players more. At the beginning of the experiment each of you will be assigned to one of two groups: circle or triangle, and will be assigned symbols (external and internal) and a label. Your symbols are fixed for all 10 rounds in Part 1 while your label will change in each round.
In Phase 1, you can propose connections to other players. Each proposed connection will cost you 2 points. If you propose to a player who also proposes to you, the connection between the two of you is active.
In Phase 2, you will choose an action: Up or Down. You will earn points for each of your active connections that chooses the same action as you (coordinate), including yourself. The points you earn depend on your group and the action you choose as follows:
If your group is ◯ and you:
In Phase 3, you will see a summary of your choices and points. You will see how many of your active connections your coordinated with, how many points you get from your coordinations minus the cost you pay for your proposed connections.
The experiment has 2 parts of 10 rounds each (20 in total). In both parts you will interact
with the same other {{ Constants.others }} players. At the end of the experiment the computer will
randomly select one round from Part 1 and one round from Part 2. The total points you earned in the two
selected rounds will determine your payment. We will convert the points into Euros using the following
exchange rate: {{ Constants.exchange }} points = 1 Euro. You will receive your earnings in cash.

| Prev | Up | Chapter 11. Indexes | Next |
All indexes in PostgreSQL are secondary indexes, meaning that each index is stored separately from the table's main data area (which is called the table's heap in PostgreSQL terminology). This means that in an ordinary index scan, each row retrieval requires fetching data from both the index and the heap. Furthermore, while the index entries that match a given indexable WHERE condition are usually close together in the index, the table rows they reference might be anywhere in the heap. The heap-access portion of an index scan thus involves a lot of random access into the heap, which can be slow, particularly on traditional rotating media. (As described in Section 11.5, bitmap scans try to alleviate this cost by doing the heap accesses in sorted order, but that only goes so far.)
To solve this performance problem, PostgreSQL supports index-only scans, which can answer queries from an index alone without any heap access. The basic idea is to return values directly out of each index entry instead of consulting the associated heap entry. There are two fundamental restrictions on when this method can be used:
The index type must support index-only scans. B-tree indexes always do. GiST and SP-GiST indexes support index-only scans for some operator classes but not others. Other index types have no support. The underlying requirement is that the index must physically store, or else be able to reconstruct, the original data value for each index entry. As a counterexample, GIN indexes cannot support index-only scans because each index entry typically holds only part of the original data value.
The query must reference only columns stored in the index. For example, given an index on columns x and y of a table that also has a column z, these queries could use index-only scans:
SELECT x, y FROM tab WHERE x = 'key'; SELECT x FROM tab WHERE x = 'key' AND y < 42;
but these queries could not:
SELECT x, z FROM tab WHERE x = 'key'; SELECT x FROM tab WHERE x = 'key' AND z < 42;
(Expression indexes and partial indexes complicate this rule, as discussed below.)
If these two fundamental requirements are met, then all the data values required by the query are available from the index, so an index-only scan is physically possible. But there is an additional requirement for any table scan in PostgreSQL: it must verify that each retrieved row be "visible" to the query's MVCC snapshot, as discussed in Chapter 13. Visibility information is not stored in index entries, only in heap entries; so at first glance it would seem that every row retrieval would require a heap access anyway. And this is indeed the case, if the table row has been modified recently. However, for seldom-changing data there is a way around this problem. PostgreSQL tracks, for each page in a table's heap, whether all rows stored in that page are old enough to be visible to all current and future transactions. This information is stored in a bit in the table's visibility map. An index-only scan, after finding a candidate index entry, checks the visibility map bit for the corresponding heap page. If it's set, the row is known visible and so the data can be returned with no further work. If it's not set, the heap entry must be visited to find out whether it's visible, so no performance advantage is gained over a standard index scan. Even in the successful case, this approach trades visibility map accesses for heap accesses; but since the visibility map is four orders of magnitude smaller than the heap it describes, far less physical I/O is needed to access it. In most situations the visibility map remains cached in memory all the time.
In short, while an index-only scan is possible given the two fundamental requirements, it will be a win only if a significant fraction of the table's heap pages have their all-visible map bits set. But tables in which a large fraction of the rows are unchanging are common enough to make this type of scan very useful in practice.
To make effective use of the index-only scan feature, you might choose to create indexes in which only the leading columns are meant to match WHERE clauses, while the trailing columns hold "payload" data to be returned by a query. For example, if you commonly run queries like
SELECT y FROM tab WHERE x = 'key';
the traditional approach to speeding up such queries would be to create an index on x only. However, an index on (x, y) would offer the possibility of implementing this query as an index-only scan. As previously discussed, such an index would be larger and hence more expensive than an index on x alone, so this is attractive only if the table is known to be mostly static. Note it's important that the index be declared on (x, y) not (y, x), as for most index types (particularly B-trees) searches that do not constrain the leading index columns are not very efficient.
In principle, index-only scans can be used with expression indexes. For example, given an index on f(x) where x is a table column, it should be possible to execute
SELECT f(x) FROM tab WHERE f(x) < 1;
as an index-only scan; and this is very attractive if f() is an expensive-to-compute function. However, PostgreSQL's planner is currently not very smart about such cases. It considers a query to be potentially executable by index-only scan only when all columns needed by the query are available from the index. In this example, x is not needed except in the context f(x), but the planner does not notice that and concludes that an index-only scan is not possible. If an index-only scan seems sufficiently worthwhile, this can be worked around by declaring the index to be on (f(x), x), where the second column is not expected to be used in practice but is just there to convince the planner that an index-only scan is possible. An additional caveat, if the goal is to avoid recalculating f(x), is that the planner won't necessarily match uses of f(x) that aren't in indexable WHERE clauses to the index column. It will usually get this right in simple queries such as shown above, but not in queries that involve joins. These deficiencies may be remedied in future versions of PostgreSQL.
Partial indexes also have interesting interactions with index-only scans. Consider the partial index shown in Example 11-3:
CREATE UNIQUE INDEX tests_success_constraint ON tests (subject, target) WHERE success;
In principle, we could do an index-only scan on this index to satisfy a query like
SELECT target FROM tests WHERE subject = 'some-subject' AND success;
But there's a problem: the WHERE clause refers to success which is not available as a result column of the index. Nonetheless, an index-only scan is possible because the plan does not need to recheck that part of the WHERE clause at run time: all entries found in the index necessarily have success = true so this need not be explicitly checked in the plan. PostgreSQL versions 9.6 and later will recognize such cases and allow index-only scans to be generated, but older versions will not.


Game
问题描述 :
Flynn and oooccc1 are playing game some day. The game is played on a rooted graph which is an undirected graph with every edge attached by some path to a special vertex called the root or the ground. The ground is denoted in the figure that follows by a dotted line. You could see it from the figure.
On each step, one player could chop out one edge, and removing that edge and anything not connected to the ground. The one who have nothing to chop with fails.
Flynn is the one who is going to move. Help him by telling him if it is possible to win by carefully choose the edge to chop with.

Learn how to fill in a gap in a model with the fit_loop tool.
First, let's set up the example data (described in more detail here):
Get the files from the Phenix regression directory and change into the new folder:
phenix.setup_tutorial tutorial_name=model-building-scripting
cd model-building-scripting
Type phenix.python
to start up Python with the Phenix environment all set up:
phenix.python
Set up the high level objects, so we can start our task:
from iotbx.data_manager import DataManager # Load in the DataManager
dm = DataManager() # Initialize the DataManager and call it dm
dm.set_overwrite(True) # Overwrite files with the same name
mmm = dm.get_map_model_manager( # getting a map_model_manager
model_file="short_model_main_chain_box.pdb", # model file
map_files="short_model_box.ccp4") # map file
We can fill in the resolution and experiment type and get a model_building object:
mmm.set_resolution(3) # resolution is 3 A
mmm.set_experiment_type('cryo_em') # it is a cryo-EM map
build = mmm.model_building() # get a model-building object
Let’s remove some residues in this model to create a model that needs a loop (we don’t have to do this, but it makes this example clearer):
new_model = build.model().apply_selection_string( # apply a selection
' not (chain A and resseq 516:519)' ) # remove residues 516-519 chain A
build.set_model(new_model) # replace existing model with new_model
You can read about how to specify selections in the Phenix selection syntax documentation. The apply_selection_string
method is part of a model object and it applies the selection you specify and returns a new model based on that selection.
Let’s write out the working model:
dm.write_model_file(build.model(), 'model_without_loop.pdb') # new model
We can choose which methods to use in loop fitting. Let’s use resolve loop fitting:
build.set_defaults(fit_loop_methods=['resolve']) #choose just resolve loop fitting
And let’s fit a loop. If were are already residues where the loop is to go (between residues 515 and 520) they would be removed before the loop is built:
fit_loop_model=build.fit_loop( # fit a loop
chain_id="A", # chain ID
loop_sequence = 'RVLD', # Sequence of residues in loop
last_resno_before_loop=515, # Residue number just before loop
first_resno_after_loop=520,) # Residue number just after loop
Let’s insert the loop:
build.insert_fitted_loop() # insert the loop
Finally let’s write out the new model:
dm.write_model_file(build.model(), 'fitted_loop_model.pdb') # new model

Introduction
Project 2 of the CSC 460 Real Time Operating Systems (RTOS) course involved designing and implementing a time triggered architecture (TTA) based scheduler. A TTA scheduler is simple way to implement an RTOS that strips away many of the complex features of a priority-based RTOS such as context switching and inter-process communication. As a result of its simplicity, it also lacks some of the flexibility that comes with these more advanced real time operating systems. However, these features introduce safety and reliability concerns, as they are difficult to implement and difficult for programers to use correctly. Without these complex components, TTAs are safe, reliable, and simple to implement.
Our task for project 2 was to extend the TTA scheduler provided for project 1 to include support for Interrupts, dynamically created tasks and multiple task instances. In particular, our solution was required to dynamically schedule new tasks without interfering with any existing periodic tasks.
Hardware
There were three pieces of hardware used in developing the TTA scheduler for Project 2, including an Arduino Mega 2560, Arduino LCD shield, and a pushbutton. A wiring diagram of this hardware is shown in Figure 1.
Software: Enhanced TTA Scheduler
The objective of project 2 was to modify the TTA scheduler from first project to support the features necessary for project 3, which will involve control of the roomba. The primary limitation of the scheduler from project 1 was its lack of support for urgent or dynamically created tasks and its reliance on the Arduino library for timing. As outlined in class, a RTOS must be able to respond to external events (interrupts) in a timely manner without affecting the execution of critical periodic tasks. Our solutions to these problems are outlined below.
uint8_t os_add_periodic_task(uint16_t delay_ms, uint16_t period_ms, task_cb task, void *state);
The API call for the addition of periodic task is largely unchanged from project 1. The function Scheduler_StartTask
from the original scheduler has been renamed to os_add_periodic_task
, the full details of which are shown above. The only additional parameter is a state struct used to create multiple instances of the same task. The details of this functionality is explained in the section “Task Instances”.
OS Timing and Interrupts
In order to maintain the deterministic behaviour of the TTA scheduler and to avoid any potential race conditions, interrupts were disabled during the execution of any periodic or timing-critical tasks. This way, there is no possibility of an interrupt service routine affecting the timing of a periodic task. As outlined in the project 2 description, the expected execution time of tasks in our roomba application and overall cpu utilization are relatively small, and therefore disabling interrupts for the entire execution period is acceptable. Any interrupt that does occur during the execution of a timing-critical task will have be handled by its appropriate ISR immediately after the scheduler re-enables interrupts using the SREG register.
Disabling interrupts during periodic tasks presented an unexpected challenge when attempting to maintain a consistent and correct dispatch schedule. This was because the original TTA scheduler used the arduino library function “millis()” to keep track of it’s execution time, which in turned relied on a configured ISR to update an internal counter for the total number of elapsed milliseconds. This means that if a timing-critical task ran for longer than a millisecond (during which interrupts are disabled), OS timing could be affected.
In order to correct this, a hardware-based timing solution was devised. As the prescalers on the for the 16-bit AVR timers are not suited for counting milliseconds directly, two timers were used in combination to directly count milliseconds with a suitably long roll-over period. Timer 3 was configured to CTC mode (clear timer on compare) to generate an external clock signal with a period of 1 ms. This was then connected with a hardware wire to Timer 5, which was configured to count this external input. In this way, our “millis()” function simply read the 16-bit timer register TCNT5 to determine the number of elapsed milliseconds, which was updated by the AVR timer hardware without any interrupts. Figure 2 provides a block diagram for this timer setup.
Dynamic Tasks
Our enhanced TTA added support for two types of non-periodic tasks that can dynamically added from any part of the code, including an ISR. The first are sporadic tasks which have an desired start time given as an offset from the time the function “os_add_sporadic_task()” is called. Our TTA scheduler will try to run the given task as close to this time as possible, but will delay further if this time conflicts with the scheduling of a periodic task. The second type of dynamic tasks are idle tasks, which do not have an associated start time and are run as soon as possible. Note that the scheduler will run all ready periodic and sporadic tasks before attempting to run an idle (background) task. This means that in our operating system, a sporadic task with a delay of zero has a higher priority than an idle task.
For both types of tasks, the scheduler will automatically delete the task from its internal queue after it has been run once. The API functions to add each type of task are given below. As before, a state struct can be provided in order to run multiple instances of the same task.
uint8_t os_add_sporadic_task(uint16_t delay_ms, uint32_t duration_us, task_cb task, void *state);
uint8_t os_add_idle_task(uint32_t duration_us, task_cb task, void *state);
Note that both functions accept an integer argument “duration_us”. This argument is the estimated execution time of the task provided by the programmer to the scheduler. This is used by the scheduler to determine if it has enough time to run a given dynamic task between other scheduled periodic and sporadic tasks. In general, the scheduler will run dynamic tasks of the same priority (i.e. sporadic versus idle) in FIFO order, but may run a later task earlier if it is able to due to shorter expected duration.
It is critical that the programmer provide accurate duration estimates of any dynamic tasks to the scheduler. Estimates that are excessively large will cause the scheduler to wait too long to run the task. Estimates that are too short may cause the dynamic task to conflict with a scheduled periodic task, causing jitter.
Task Instances
As outlined above, each scheduler API call accepts a pointer to a “state” struct, that stores information used by the specific instance of the task callback “task”. In this way, the same task callback can be used for multiple instances of the task that maintain different state. The use of a void pointer type makes the struct generic in the scheduler API; each task callback is responsible for casting the struct to the appropriate type.
typedef void (*task_cb)(void *state);
The type of the task function pointer “task_cb” was updated to match the addition of this state structure. As shown above, each task callback now expects the state structure as a single argument when it is called by the scheduler.
Error Handling
The last critical feature that was added to the TTA scheduler was the ability to detect and respond to timing jitter. In the case of infrequent jitter caused by a single long-running task (either periodic, sporadic or idle), the provided code from project 1 is already able to correct itself and resume the proper periodic schedule. However, there was no way to detect how much jitter was occuring, or determine when a given amount of jitter was unrecoverable.
To support these features, we added variables that calculate and accumulate the total jitter detected across all periodic tasks. Timing jitter was defined as the difference between the scheduled time and the time when the task was actually run. If this total jitter passed a predefined allowable jitter, the scheduler was configured to hang and return an error status. Note that this accumulated jitter is reset every second as the scheduler may need to run for a long period of time.
Hardware
The hardware for phase one consists of 3 sources of input: the joysticks analog movements along the X and Y axis, the analog value of the photocell, and the digital state of the joystick’s button.
It also consists of 3 outputs: the laser, the pair of servo motors used to drive the pan and tilt, and the LCD display.
Testing
A series of test cases were constructed to fully test the TTA features outlined above. Each case is presented with a brief description, the expected scheduling result and a screenshot of actual scheduling shown on a logic analyzer.
Test 1
Test Case
Test Case
Valid schedule with 4 periodic tasks.
Description
This test case runs 4 periodic tasks. The periodic tasks have offsets of 0, 5, 10, 15 ms, durations of 4, 1, 3, 3 ms, and periods of 20ms. These tasks are scheduled such that they should run simultaneously with no jitter
Expected Results
This should run with no problems. The logic analyzer should show 4 periodic tasks with minimal to no jitter.
Observed Results
The logic analyzer showed (Figure 3) 4 periodic tasks repeating with no jitter.
Test 2
Test Case
Test Case
Valid schedule with 2 periodic tasks and interrupt triggering sporadic tasks.
Description
This test case runs 2 periodic tasks with an interrupt triggering an idle sporadic task. The periodic tasks have offsets of 0 and 5 ms, durations of 4 and 1 ms, and periods of 20ms. Pressing a button triggers an interrupt which schedules a sporadic task with delay 0, meaning it should start as soon as possible.
Expected Results
This should run with no problems. The logic analyzer should show 2 periodic tasks with minimal jitter. When a sporadic task is triggered, it should fall into the idle time between periodic task executions. It should not introduce any jitter to the periodic tasks.
Observed Results
The logic analyzer showed (Figure 4) 2 periodic tasks with a sporadic tasks occuring during the scheduler's idle time.
Test 3
Test Case
Test Case
Varying Sporadic Tasks
Description
This test case spawns two periodic tasks, one with offset 0ms, duration 4ms, and frequency 20ms, the other with offset 5ms, duration 1ms, and frequency 20ms. When the button is pressed it triggers a sporadic task with delay 0ms and duration 2ms. This means that the sporadic task should run as soon as there is enough idle time between periodic tasks for it to complete given its duration. In this case, the sporadic task schedules another sporadic task with a delay equal to the number of times the sporadic task has already been scheduled. As the instances of the sporadic tasks grow further apars, it will eventually force a conflict between them and the periodic tasks, forcing the scheduler to determine which task should run. It also tests the scheduler's ability to calculate remaining idle time and compare it to the estimated duration of a sporadic task.
This test case also tests the functionality of providing a sporadic task with a delay, such that it does not run immediately but instead runs in the future after some specified time.
Expected Results
The periodic tasks should run with no jitter. The sporadic tasks should run in between the sporadic tasks when there is enough idle time to complete them before the next periodic tasks. The logic analyzer should show two periodic tasks with one sporadic task repeating, but getting further and further apart.
Observed Results
The logic anaylzer showed (Figure 5) 2 periodic tasks with multiple sporadic tasks repeating in the idle periods, but never introducing jitter to the periodic tasks.
Test 4
Test Case
Test Case
Invalid schedule
Description
This test case schedules 3 periodic tasks, two of which start at the same time. Since only one task can run at a time, this schedule guarantees there will be jitter in at least one of the tasks every period.
Expected Results
The OS should recognize this is an invalid schedule and display an error message on the LCD screen and hang. The logic analyzer should show two of the periodic tasks running correctly, with the other one shifted the duration of the first tasks off its period. This should only show for a short period of time, when the scheduler should hang and the logic analyzer should show nothing.
Observed Results
The logic analyer showed (Figure 6) significant jitter in one of three periodic tasks, followed by the scheduler hanging.
Test 5
Test Case
Test Case
Sporadic and Idle Task Conflic
Description
A sporadic task and an idle (background) task are scheduled to start at the same time. Since idle tasks have no specified running time associated with them (i.e they just run as soon as possible), and sporadic tasks do have a specified time to run, the sporadic tasks should be given precedence over the idle task and run first.
Expected Results
The sporadic task should run before the idle task.
Observed Results
The logic analyzer showed (Figure 7) the sporadic (shorter) task running before the idle (longer) task.
Test 6
Test Case
Test Case
Valid schedule with interrupt causing occasional jitter
Description
Two periodic tasks run with periods of 20 ms. A long, sporadic task is scheduled via an interrupt. The duration of the sporadic task is set to 2ms, but the actual running duration of it is 10ms. This causes the scheduler to attempt to run the task in the idle time before one of the periodic tasks because it thinks there is enough idle time to complete it. When the sporadic task exceeds its duration it will cause jitter in the periodic task. The amount of jitter introduced should be under the tolerable and recoverable amount, so the scheduler should make up, continue, and recover the periods of the periodic tasks.
Expected Results
This should run with no problems. The logic analyzer should show 2 periodic tasks with minimal jitter. When a sporadic task is triggered, it should cause jitter in the periodic tasks as the actual run time (10ms) is larger than the expected runtime (2ms). The scheduler should be able to recover from this. If the button is pressed repeatedly (causing frequent interrupts), there will be too much error and the scheduler will detect this and hang.
Observed Results
The logic analyzer showed (Figure 8) 2 periodic tasks with occasional jitter caused by a sporadic task being scheduled too close to the beginning of a periodic task.
Test 7
Test Case
Test Case
Sporadic Task FIFO
Description
This test case has 2 periodic tasks running, with an interrupt caused by a button press that schedules 3 sporadic tasks all with delay 0. The two sporadic tasks scheduled first are of the same length, and have estimated durations of 11ms and 9ms. The third sporadic tasks has an estimated duration of 1ms.
Expected Results
The sporadic tasks should be completed in a first in-first out (FIFO) order, unless they are triggered at a time where the schedule determines that based on the estimated durations it does not have enough idle time before the next periodic tasks to complete the next sporadic task, but does have enough time to complete a later sporadic task. In this case, the later sporadic task should be run first.
Observed Results
The logic analyzer showed (Figure 9) two periodic tasks running and three non-periodic tasks running, of which the shortest (last scheduled) ran first, followed by the longest (first scheduled) and then the middle (second scheduled) tasks, where there would not have been time to run either of the longer two before a periodic task, but there was time to run the shortest one.
Test 8
Test Case
Test Case
Constant Idle Tasks
Description
This test case has 2 periodic tasks running, and when those two tasks are idle, it is to run a sporadic tasks that schedules itself again with a delay of 0. This test is designed to ensure that even with constant idle and sporadic tasks being scheduled, the scheduler will not introduce jitter into the periods of the periodic tasks, and will respect their priority.
Expected Results
The 2 periodic tasks should experience no jitter, and the sporadic tasks should fill the majority of the idle time between periodic tasks.
Observed Results
The logic analyzer showed (Figure 10) two periodic tasks with no jitter, where the idle space between them was filled by recursive sporadic tasks. The sporadic tasks did not interfere with the periods.
Conclusion
The test cases described above show that the TTA scheduler met the requirements for project 2. Specifically, our scheduler was able to respond to interrupts in order to add and delete tasks dynamically, without interfering with the scheduling of any of the periodic tasks. Clearly, a TTA scheduler provides a viable, simple alternative to the traditional priority-based RTOS that was seen in the lab.
Observations and Future Improvements
While disabling interrupts during timing-critical tasks provided extremely deterministic scheduling performance for project 2, it may be unnecessary for project 3. With careful programming, ISRs can be kept extremely short and free of race conditions; they can simply exist to schedule dynamic tasks for some time in the future. Short ISRs would likely not introduce any significant jitter into the currently executing critical task. Furthermore, having the OS schedule dynamic tasks immediately may provide better scheduling performance.

These are the transaction abstraction's interfaces and classes. These types
define a two-phase commit protocol for driving transactions in a
distributed system. These types define the actors and actions in the
protocol but not the transaction semantics or transaction participant
interactions with the manager. These are defined by particular
implementations of the Transaction
and
NestableTransaction
interfaces. The default semantics
and participant/manager interactions are defined in the subpackage

Looking in the mirror
Foundation Core Skills
What are three new things you have learned about yourself and your ego as a result of the core learning?
- That once I fully grasp a concept, I tend to get a lot more confident and excited about tackling more difficult problems.
- I've most definitely got the capacity to learn new concepts, but getting better at those things will take time and practice.
- Speed kills, sometimes. I can get too eager to jump into doing an exercise and neglect reading the whole thing properly or coming up with a plan for success.
What are the role of values, empathy and self awareness in learning and programming?
Values will guide your decision making on what work to take on and how to deal with people that don't treat you in a manner that aligns with those values. Empathy will help you work with people from all walks of life, as well as facilitate the building of relationships. That, combined with self awareness will aid in preventing and/or resolving any conflicts you might encounter. A healthy self awareness will also help you overcome any learning obstacles, as you will be able to recognise when you are getting down on yourself and utilise other tools in you skillset to get you out of that funk.
What has surprised you the most about the core learning?
Listening and looping was amazing. It's such a good exercise, as it helps you develop your mindfullness, self awareness and your empathy skills.
What were the most challenging aspects of the core learning?
The identity and values exploration was quite an intense exercise. Reflecting on who you really are can sometimes be uncomfortable and bring up things that you're not necessarily wanting to, but incredibly valuable when you take it seriously, as it can really help you evaluate what's important to you and your situation in life.
Why do you think we, a programming school, are spending so much time focusing on core learning in a web development bootcamp course?
The pandemic has brought working practices into stark perspective. Remote working is going to become a much more readily accepted option for businesses, and as I personally have experienced during the lockdown, online communication can be tricky at times. Therefore, have good HR skills is an absolute must in that situation, as is when working as part of a team, which is what a lot of programmers end up doing. The core components of the course just helps you become a more well-rounded and resilient person and programmer.
Does the time you spent studying core learning here feel like a waste of time? Should you have just used that time to practicing programming instead? Justify your answer.
In short, no. The core learning has really had a positive effect on how I learn as well as keeping up my determination to push through difficult situations (in a problem solving sense).

"Once Upon a Time in China" is considered a classic in its country of origin. First released in 1991, the film was popular enough to spawn a number of imitators, not to mention five sequels. Watching the original, it's easy to understand why. The sprawling adventure showcases the charismatic Jet Li and features romance, intrigue, picturesque settings and a string of remarkably inventive fight scenes. What's not to like?
Jet Li stars as the legendary Chinese hero Wong Fei-Hong (nearly 100 films have been made about the icon, including Jackie Chan's "The Legend of Drunken Master"). The actor does his own stunts (with some wirework to jazz up the proceedings) and the results are spectacular. In addition to the amazing battles, the story offers an interesting look at another culture.
Set in the late 19th century, "Once Upon a Time in China" (in Cantonese with English subtitles) shows a populace under siege from the outside world. More and more often, colonial forces from the United States and Britain turn up on native shores. Their presence is intimidating, to say the least, but the indigenous people have no intention of succumbing. Their resistance ranges from small (neighborhood musicians play and sing at top volume to drown out the hymns of western missionaries) to full-scale military face-offs.
The head of a healing clinic, Wong is asked by a general in the Black Flag army to teach the locals self-defense by training them in the art of kung fu. Things get complicated with the arrival of Wong's "Aunt" Yee (Rosamund Kwan), just back from a two-year stay in the West. Despite her title, Yee and Wong are not related and romance simmers between the two (watch for a lovely bit of shadow flirting from Yee).
As for bad guys, there are too many here to keep track of. A gang from a neighboring town tries to extort local businessmen, corrupt government officials abound, and then there are those nasty foreigners. I tried to keep up with them all, but soon gave up. My advice to you is to keep your eyes on Wong, his comrades and Yee, and just watch the fireworks. You can sort out the particulars on subsequent viewings.
And you will want to watch it again. While early segments of "Once Upon a Time in China" contain some embarrassing low comedy, Jet Li's performance, coupled with his kung fu wizardry, carries the viewer through any shaky patches. The fight scenes are the main attraction, of course, and the film delivers the goods again and again. My favorite is a segment where Wong and his foe use ladders in a breathtaking duel. Have fun choosing your own.

I did finish my 3 months internship few weeks ago and I reworked my blog site during these holidays so that I won’t be boring.
I was thinking about to design my own Jekyll theme for a long time and I did finally achieve the goal, cheers! As you can see, this blog is my first github open source project and I got already 4 stars at the moment. Such an accomplishment! Therefor, I will keep working on this project and make it better. If you have any question or suggestion, feel free to leave a message here or open an issue at Github, I will try my best to make this theme to be your best friend while you want write something down.
Look back into the last three months, it was a wonderful experience to work on what I really love. I did complete two projects, the first one is a presentation website for a Chinese air condition manufacturer – VeckChina, and the second one is a ruby on rails e-commerce project for a Parisian restaurant – Msushi. I made a lot of progresses of coding skills and negotiation abilities. And I did learn what and how to do when there is a conflict between developer and designer or between customer and company.
Now it’s time to moving on, I am on the train to Marseille while writing this post. Hope everything will be ok.
