SAVEPOINT
Section: SQL Commands (7)Updated: 2012-08-14
Index Return to Main Contents
NAME
SAVEPOINT - define a new savepoint within the current transactionSYNOPSIS
SAVEPOINT savepoint_name
DESCRIPTION
SAVEPOINT establishes a new savepoint within the current transaction.
A savepoint is a special mark inside a transaction that allows all commands that are executed after it was established to be rolled back, restoring the transaction state to what it was at the time of the savepoint.
PARAMETERS
- savepoint_name
- The name to give to the new savepoint.
NOTES
Use ROLLBACK TO SAVEPOINT [rollback_to_savepoint(7)] to rollback to a savepoint. Use RELEASE SAVEPOINT [release_savepoint(7)] to destroy a savepoint, keeping the effects of commands executed after it was established.
Savepoints can only be established when inside a transaction block. There can be multiple savepoints defined within a transaction.
EXAMPLES
To establish a savepoint and later undo the effects of all commands executed after it was established:
BEGIN; INSERT INTO table1 VALUES (1); SAVEPOINT my_savepoint; INSERT INTO table1 VALUES (2); ROLLBACK TO SAVEPOINT my_savepoint; INSERT INTO table1 VALUES (3); COMMIT;The above transaction will insert the values 1 and 3, but not 2.
To establish and later destroy a savepoint:
BEGIN; INSERT INTO table1 VALUES (3); SAVEPOINT my_savepoint; INSERT INTO table1 VALUES (4); RELEASE SAVEPOINT my_savepoint; COMMIT;The above transaction will insert both 3 and 4.
COMPATIBILITY
SQL requires a savepoint to be destroyed automatically when another savepoint with the same name is established. In PostgreSQL, the old savepoint is kept, though only the more recent one will be used when rolling back or releasing. (Releasing the newer savepoint will cause the older one to again become accessible to ROLLBACK TO SAVEPOINT and RELEASE SAVEPOINT.) Otherwise, SAVEPOINT is fully SQL conforming.

The Braces Matching SPI for implementing BracesMatcher
s that can search
through a document and find matching areas of text.
Implementations of BracesMatcherFactory
can be registered in MimeLookup
under the mime type of documents that they wish to create BracesMatcher
s for.
The infrastructure behind the SPI registers a special highlighting layer for visualization of search results
provided by registered matchers. The highlighting layer uses Highlighting SPI
to
colorify parts of a document in a text component that have been identified by matchers. The infrastructure also
supplies an action for moving componet's caret between those areas. The action is registered
for all supported document types and bound to a shortcut.


Apache Beam Contribution Guide
The Apache Beam community welcomes contributions from anyone with a passion for data processing! Beam has many different opportunities for contributions – write new examples, add new user-facing libraries (new statistical libraries, new IO connectors, etc), work on the core programming model, build specific runners (Apache Apex, Apache Flink, Apache Spark, Google Cloud Dataflow, etc), or participate on the documentation effort.
We use a review-then-commit workflow in Beam for all contributions.
For larger contributions or those that affect multiple components:
- Engage: We encourage you to work with the Beam community on the Apache JIRA issue tracker and developer’s mailing list to identify good areas for contribution.
- Design: More complicated contributions will likely benefit from some early discussion in order to scope and design them well.
For all contributions:
- Code: The best part ;-)
- Review: Submit a pull request with your contribution to our GitHub mirror. Work with a committer to review and iterate on the code, if needed.
- Commit: A Beam committer merges the pull request into our Apache repository.
We look forward to working with you!
Engage
Mailing list(s)
We discuss design and implementation issues on the<EMAIL_ADDRESS>mailing list, which is archived
here. Join by
emailing
<EMAIL_ADDRESS>.
If interested, you can also join the other mailing lists.
JIRA issue tracker
We use the Apache Software Foundation’s JIRA as an issue tracking and project management tool, as well as a way to communicate among a very diverse and distributed set of contributors. To be able to gather feedback, avoid frustration, and avoid duplicated efforts all Beam-related work should be tracked there.
If you do not already have an Apache JIRA account, sign up here.
If a quick search doesn’t turn up an existing JIRA issue for the work you want to contribute, create it. Please discuss your idea with a committer or the component lead in JIRA or, alternatively, on the developer mailing list.
If there’s an existing JIRA issue for your intended contribution, please comment about your intended work. Once the work is understood, a committer will assign the issue to you. (If you don’t have a JIRA role yet, you’ll be added to the “contributor” role.) If an issue is currently assigned, please check with the current assignee before reassigning.
For moderate or large contributions, you should not start coding or writing a design document unless there is a corresponding JIRA issue assigned to you for that work. Simple changes, like fixing typos, do not require an associated issue.
Online discussions
We don’t have an official IRC channel. Most of the online discussions happen in the Apache Beam Slack channel. If you want access, you need to send an email to the user mailing list to request access.
Chat rooms are great for quick questions or discussions on specialized topics. Remember that we strongly encourage communication via the mailing lists, and we prefer to discuss more complex subjects by email. Developers should be careful to move or duplicate all the official or useful discussions to the issue tracking system and/or the dev mailing list.
Design
To avoid potential frustration during the code review cycle, we encourage you to clearly scope and design non-trivial contributions with the Beam community before you start coding.
Generally, the JIRA issue is the best place to gather relevant design docs, comments, or references. It’s great to explicitly include relevant stakeholders early in the conversation. For designs that may be generally interesting, we also encourage conversations on the developer’s mailing list.
We suggest using Google Docs for sharing designs that may benefit from diagrams or comments. Please remember to make the document world-commentable and add a link to it from the relevant JIRA issue. You may want to start from this template.
Code
To contribute code to Apache Beam, you’ll have to do a few administrative steps once, and then follow a few guidelines for each contribution.
When developing a new PTransform
, consult the PTransform Style Guide.
One-time Setup
[Potentially] Submit Contributor License Agreement
Apache Software Foundation (ASF) desires that all contributors of ideas, code, or documentation to the Apache projects complete, sign, and submit an Individual Contributor License Agreement (ICLA). The purpose of this agreement is to clearly define the terms under which intellectual property has been contributed to the ASF and thereby allow us to defend the project should there be a legal dispute regarding the software at some future time.
We require you to have an ICLA on file with the Apache Secretary for larger contributions only. For smaller ones, however, we rely on clause five of the Apache License, Version 2.0, describing licensing of intentionally submitted contributions and do not require an ICLA in that case.
Obtain a GitHub account
We use GitHub’s pull request functionality to review proposed code changes.
If you do not already have a personal GitHub account, sign up here.
Fork the repository on GitHub
Go to the Beam GitHub mirror and fork the repository to your own private account. This will be your private workspace for staging changes.
 Feel free to repeat these steps on all machines that you want to use for development.
We assume you are using SSH-based authentication with GitHub. If necessary, exchange SSH keys with GitHub by following their instructions.
Clone Beam’s read-only GitHub mirror.
$ git clone https://github.com/apache/beam.git
$ cd beam
Add your forked repository as an additional Git remote, where you’ll push your changes.
$ git remote add <GitHub_user> git@github.com:<GitHub_user>/beam.git
You are now ready to start developing!
[Python SDK Only] Set up a virtual environemt
We recommend setting up a virtual envioment for developing Python SDK. Please see instructions available in Quickstart (Python) for setting up a virtual environment.
[Optional] IDE Setup
Depending on your preferred development environment, you may need to prepare it to develop Beam code. We have some collected tips for IntelliJ and Eclipse.
Create a branch in your fork
You’ll work on your contribution in a branch in your own (forked) repository.
Create a local branch, initialized with the state of the branch you expect your
changes to be merged into. Keep in mind that we use several branches, including
master
, feature-specific, and release-specific branches. If you are unsure,
initialize with the state of the master
branch.
$ git fetch --all
$ git checkout -b <my-branch> origin/master
At this point, you can start making and committing changes to this branch in a standard way.
Syncing and pushing your branch
Periodically while you work, and certainly before submitting a pull request, you should update your branch with the most recent changes to the target branch.
$ git pull --rebase
Remember to always use --rebase
parameter to avoid extraneous merge commits.
Then you can push your local, committed changes to your (forked) repository on GitHub. Since rebase may change that branch’s history, you may need to force push. You’ll run:
$ git push <GitHub_user> <my-branch> --force
Testing
All code should have appropriate unit testing coverage. New code should have new tests in the same contribution. Bug fixes should include a regression test to prevent the issue from reoccurring.
Java SDK
For contributions to the Java code, run unit tests locally via Maven.
$ mvn clean verify
Python SDK
For contributions to the Python code, you can use command given below to run unit tests locally. If you update any of the cythonized files in Python SDK, you must install “cython” package before running following command to properly test your code. We recommend setting up a virtual environment before testing your code.
$ python setup.py test
You can use following command to run a single test method.
$ python setup.py test -s <module>.<test class>.<test method>
To Check for lint errors locally, install “tox” package and run following command.
$ pip install tox
$ tox -e lint
Beam supports running Python SDK tests using Maven. For this, navigate to root directory of your Apache Beam clone and execute following command. Currently this cannot be run from a virtual environment.
$ mvn clean verify -pl sdks/python
Review
Once the initial code is complete and the tests pass, it’s time to start the code review process. We review and discuss all code, no matter who authors it. It’s a great way to build community, since you can learn from other developers, and they become familiar with your contribution. It also builds a strong project by encouraging a high quality bar and keeping code consistent throughout the project.
Create a pull request
Organize your commits to make a committer’s job easier when reviewing. Committers normally prefer multiple small pull requests, instead of a single large pull request. Within a pull request, a relatively small number of commits that break the problem into logical steps is preferred. For most pull requests, you’ll squash your changes down to 1 commit. You can use the following command to re-order, squash, edit, or change description of individual commits.
$ git rebase -i origin/master
You’ll then push to your branch on GitHub. Note: when updating your commit after pull request feedback and use squash to get back to one commit, you will need to do a force submit to the branch on your repo.
Navigate to the Beam GitHub mirror to create a pull request. The title of the pull request should be strictly in the following format:
[BEAM-<JIRA-issue-#>] <Title of the pull request>
Please include a descriptive pull request message to help make the comitter’s job easier when reviewing. It’s fine to refer to existing design docs or the contents of the associated JIRA as appropriate.
If you know a good committer to review your pull request, please make a comment like the following. If not, don’t worry – a committer will pick it up.
Hi @<GitHub-committer-username>, can you please take a look?
When choosing a committer to review, think about who is the expert on the
relevant code, who the stakeholders are for this change, and who else would
benefit from becoming familiar with the code. If you’d appreciate comments from
additional folks but already have a main committer, you can explicitly cc them
using @<GitHub-committer-username>
.
Code Review and Revision
During the code review process, be careful about whether and when to rebase your branch or otherwise modify published commits, since this can remove existing comment history and be confusing to the committer when reviewing. When you make a revision, always push it in a new commit.
Our GitHub mirror automatically provides pre-commit testing coverage using Jenkins. Please make sure those tests pass; the contribution cannot be merged otherwise.
LGTM
Once the committer is happy with the change, they’ll respond with an LGTM (“looks good to me!”). At this point, the committer may ask you to tidy up the commit history before they merge your changes into the codebase. This makes it easy for community to look through the history and understand how something came about, look for a candidate commit to roll back, etc.
In the case the author is also a committer, either can merge the pull request. Just be sure to communicate clearly whose responsibility it is in this particular case.
Thank you for your contribution to Beam!
Deleting your branch
Once the pull request is merged into the Beam repository, you can safely delete the branch locally and purge it from your forked repository.
From another local branch, run:
$ git fetch --all
$ git branch -d <my-branch>
$ git push <GitHub_user> --delete <my-branch>
Stale pull requests
The community will close stale pull requests in order to keep the project healthy. A pull request becomes stale after its author fails to respond to actionable comments for 60 days. Author of a closed pull request is welcome to reopen the same pull request again in the future. The associated JIRAs will be unassigned from the author but will stay open.
Granting more rights to a contributor
The project management committee (PMC) can grant more rights to a contributor, such as commit access or decision power, and recognize them as new committers or PMC members.
The PMC periodically discusses this topic and privately votes to grant more rights to a contributor. If the vote passes, the contributor is invited to accept or reject the nomination. Once accepted, the PMC announces the decision publicly and updates the list of team member accordingly.
The key to the selection process is Meritocracy, literally government by merit. Contributors earn merit in many ways: contributing code, testing releases, participating in documentation effort, answering user questions, debating design proposals, triaging issues, evangelizing the project, growing user base, and any other action that benefits the project as a whole.
Therefore, there isn’t a single committer bar, e.g., a specific number of commits. In most cases, new committers will have a combination of different types of contributions that are hard to compare to each other. Similarly, there isn’t a single PMC bar either. The PMC discusses all contributions from an individual, and evaluates the overall impact across all the dimensions above.
Nothing gives us greater joy than recognizing new committers or PMC members – that’s the only way we can grow. If there’s ever any doubt about this topic, please email dev@ or private@ and we’ll gladly discuss.

The Logger service has, more or less, the same methods as
Console, but comes with a few handy features:
-
Namespace: when you import the LoggerModule.forRoot('MyNamespace'), you define a root namespace
for your app, and each component/service/... can inject the base logger and extend it with their own namespace. So you could end up
with something like:
And so you might see [App:AppComponent] initialized and
[App:DataService] getting data in the console (depending on your log level)
-
Log level: the log level map is stored in local storage and so can be used to debug prod applications if need be. This map's keys
serve as regexp to be evaluated against the namespace of the logger when it's created. For example, if we have a log level map like
this:
Then the example we had above will only log the message from the
DataService, because
DEBUG
is the lowest log level matching the namespace of the logger. Beware that the log level stored in local storage is only evaluated at
Logger
creation so if you change its value, you need to refresh your browser to witness the change in the
Logger.


Javascript (JS) compares to HTML and CSS in that JS makes webpage content housed in HTML and styled by CSS interactive.
Control flow refers to making decisions with code and loops is an instruction to the computer to repeat running a block of code a certain number of times or until a condition is met. To use an anlogy control flow is like deciding how you will approach drying the laundry, for example if it is sunny you will hang wet clothes up on the line while if it is cold and raining you might use a dryer instead. Loops would be like, to use the previous analogy, to keep doing loads of laundry until the laundry basket is empty.
Accessing data from an array is selecting an item from a list depending on the position of the item in the list/array.  Functions can be useful in many instances including counting up objects or making elements appear and disappear as wanted.

"ESTHER", BOOK OF The authorship of this book is unknown. It must have been obviously written after the death of Ahasuerus (the Xerxes of the Greeks), which took place B.C. 465. The minute and particular account also given of many historical details makes it probable that the writer was contemporary with Mordecai and Esther. Hence we may conclude that the book was written probably about B.C. 444-434, and that the author was one of the Jews of the dispersion. This book is more purely historical than any other book of Scripture; and it has this remarkable peculiarity that the name of God does not occur in it from first to last in any form. It has, however, been well observed that“though the name of God be not in it, his finger is.” The book wonderfully exhibits the providential government of God.

Shortest Path
问题描述 :
When YY was a boy and LMY was a girl, they trained for NOI (National Olympiad in Informatics) in GD team. One day, GD team’s coach, Prof. GUO asked them to solve the following shortest-path problem.
There is a weighted directed multigraph G. And there are following two operations for the weighted directed multigraph:
(1) Mark a vertex in the graph.
(2) Find the shortest-path between two vertices only through marked vertices.
For it was the first time that LMY faced such a problem, she was very nervous. At this moment, YY decided to help LMY to analyze the shortest-path problem. With the help of YY, LMY solved the problem at once, admiring YY very much. Since then, when LMY meets problems, she always calls YY to analyze the problems for her. Of course, YY is very glad to help LMY. Finally, it is known to us all, YY and LMY become programming lovers.
Could you also solve the shortest-path problem?

输入:
The input consists of multiple test cases. For each test case, the first line contains three integers N, M and Q, where N is the number of vertices in the given graph, N≤300; M is the number of arcs, M≤100000; and Q is the number of operations, Q ≤100000. All vertices are number as 0, 1, 2, … , N – 1, respectively. Initially all vertices are unmarked. Each of the next M lines describes an arc by three integers (x, y, c): initial vertex (x), terminal vertex (y), and the weight of the arc (c). (c > 0) Then each of the next Q lines describes an operation, where operation “0 x” represents that vertex x is marked, and operation “1 x y” finds the length of shortest-path between x and y only through marked vertices. There is a blank line between two consecutive test cases.
End of input is indicated by a line containing N = M = Q = 0.
End of input is indicated by a line containing N = M = Q = 0.

Each of the next M lines describes an arc by three integers (x, y, c): initial vertex (x), terminal vertex (y), and the weight of the arc (c). (c > 0) Then each of the next Q lines describes an operation, where operation “0 x” represents that vertex x is marked, and operation “1 x y” finds the length of shortest-path between x and y only through marked vertices. There is a blank line between two consecutive test cases.
End of input is indicated by a line containing N = M = Q = 0.
End of input is indicated by a line containing N = M = Q = 0.

思路：最短路+floyd
分析：
1 题目给的n <= 300，而边数m<=100000，并且有Q<= 100000次询问。刚开始我用优先队列+Dij然后就开始TLE，然后就没然后了。
2 看了题解之后猛然发现这尼玛就是floyd,（对算法理解不透测）。我们知道floyd就是每次都拿一个中间点k来更新dis，题目中是只有标记过的点才能够使用，那么就像floyd一样只要是标记来这个点那么就可以用这个点来进行更新dis，然后如果要求两点直间的距离只要查找即可。
代码：
#include<iostream> #include<algorithm> #include<cstdio> #include<cstring> using namespace std; #define MAXN 310 #define INF 0xFFFFFFF int n , m , Q , cnt , flag; int vis[MAXN]; int weight[MAXN][MAXN]; void init(){ for(int i = 0 ; i < n ; i++){ vis[i] = 0; for(int j = 0 ; j < n ; j++) weight[i][j] = INF; weight[i][i] = 0; } } int min(int a , int b){ return a < b ? a : b; } void floyd(int s){ for(int i = 0 ; i < n ; i++){ for(int j = 0 ; j < n ; j++) weight[i][j] = min(weight[i][s]+weight[s][j] , weight[i][j]); } } int main(){ int x , s , e , v; cnt = 1; flag = 1; while(scanf("%d%d%d" , &n , &m , &Q) && n+m+Q){ init(); for(int i = 0 ; i < m ; i++){ scanf("%d%d%d" , &s , &e , &v); if(weight[s][e] > v) weight[s][e] = v; } if(!flag) printf("\n"); else flag = 0; printf("Case %d:\n" , cnt++); for(int i = 0 ; i < Q ; i++){ scanf("%d" , &x); if(!x){ scanf("%d" , &s); if(!vis[s]){ vis[s] = 1; floyd(s);/*更新dis*/ } else printf("ERROR! At point %d\n" , s); } else{ scanf("%d%d" , &s , &e); if(!vis[s] || !vis[e]) printf("ERROR! At path %d to %d\n" , s , e); else{ if(weight[s][e] == INF) printf("No such path\n"); else printf("%d\n" , weight[s][e]); } } } } return 0; }

女猪脚就一傻逼！！！！！
女猪脚就一傻逼！！！！！
正在学习搜索，很好
很好的思路，可以借鉴
贴的有些代码的头文件不见了，这是为啥
博主，你这个是wordpress哪个主题啊，不错哦~
这个问题其实还可以找循环节。参照欧拉定理（也就是费马定理的推广）,a^(phi(m)) mod m = 1
http://zh.wikipedia.org/wiki/%E6%AC%A7%E6%8B%89%E5%AE%9A%E7%90%86_(%E6%95%B0%E8%AE%BA)
所以先算b mod phi(10)，这个部分都是可以约掉的。基本上O(1)的时间就出解了。当然，这也是因为这个问题模数太小的原因。
正解，我的方法占用的内存更多些
这个问题别太纠结了，不同的编译器结果不一
网站不错，支持一个

Global Class
The global object.
Item Index
Methods
Methods
define
-
[dependency]
-
module
Defines a module.
The define()
function is available globally.
It allows you to cleanly define and expose functionality using the javascript module pattern.
The last argument passed to define()
should be a callback function that actually defines the module.
Typically the callback returns a value (usually of the object or function type) that provides access to the functionality of the module.
For example, a module could expose a constructor, or a factory function.
Alternatively, a module could return a singleton object or a constant value.
Finally, the callback could also expose its own global properties and/or functions.
define()
lets you load and manage any dependencies your module might have.
Any dependencies can be passed as string arguments prior to the final callback argument.
Dependency argument are considered paths to javascript files that themselves typically define other modules. Relative paths are resolved against the location of the current module.
Dependencies loaded with define()
are loaded only once.
Subsequent requests for a module loaded prior are served from a module cache.
Example module in file module3.js
(function(){
//use the define() method to define module1 and module2 as dependencies
//and to create and expose a new module
define(
"tmp/module1.js", "../scripts/module2.js", //dependencies
function(module1, module2){ //callback creates the actual module.
//this callback is called after module1 and module2 are loaded
//the callback is passed those dependencies as arguments so it can use them.
return {
...define the actual module functionlity here...
};
}
);
})() //in this example, "this" passed to the module is thought to be the Global object.
Parameters:
-
[dependency]
String optional multipleModules upon which this module is dependent.
-
module
ObjectThe module being defined. This should typically be a function, but it may also be a object, or a string identifying a script.

Light-weight atomic spinlock.
A spinlock is an inter-thread synchronization primitive based on atomic operations. It allows to guard a critical section from concurrent access of multiple threads at once. It is very similar to a mutex in semantics, but inside it provides a more light-weight and fast locking mechanism without thread sleeping and undesirable context switching. Thus spinlocks should be used only for small code sections, otherwise long-time spinning can cause extensive CPU time waste by waiting threads.
As the spinlock is based on atomic operations it would have the real meaning only if an underlying atomic model is lock-free (not simulated using the mutex). You can check if the atomic model is lock-free with p_atomic_is_lock_free(). Otherwise usage of spinlocks will be the same as the ordinary mutex.
To create a new spinlock primitive the p_spinlock_new() routine should be called, to delete the unused spinlock primitive use p_spinlock_free().
Use p_spinlock_lock() or p_spinlock_trylock() to synchronize access at the beginning of the critical section. Only the one thread is allowed to pass this call, others will wait for the p_spinlock_unlock() call which marks the end of the critical section. This way the critical section code is guarded against concurrent access of multiple threads at once.

| typedef struct PSpinLock_ PSpinLock |
Spinlock opaque data structure.
Definition at line 68 of file pspinlock.h.
Frees PSpinLock object.
| spinlock | PSpinLock to free. |
It doesn't unlock spinlock before freeing memory, so you should do it manually.
If the atomic model is not lock-free this call will have the same effect as p_mutex_free().
Locks a spinlock.
| spinlock | PSpinLock to lock. |
A thread will not sleep in this call if another thread is holding the lock, instead it will try to lock spinlock in an infinite loop.
If the atomic model is not lock-free this call will have the same effect as p_mutex_lock().
Do not lock a spinlock recursively - this may lead to an application deadlock.
Tries to lock a spinlock immediately.
| spinlock | PSpinLock to lock. |
Tries to lock spinlock and returns immediately if it is not available for locking.
If the atomic model is not lock-free this call will have the same effect as p_mutex_trylock().
Do not lock a spinlock recursively - this may lead to an application deadlock.
Releases a locked spinlock.
| spinlock | PSpinLock to release. |
If spinlock was previously locked then it becomes unlocked. Any thread can unlock any spinlock. It is also safe to call this routine on an unlocked spinlock.
If the atomic model is not lock-free this call will have the same effect as p_mutex_unlock(), thus it is not safe to call this routine on an unlocked spinlock.

The Best Christmas Gifts For Music Lovers
by Leah WilliamsMusic plays a huge part in all of our lives, from our morning commute to "me" time, but some of us like music a bit more than others. Finding the perfect gifts for your audiophile friends and family can be difficult sometimes, but there's a treasure trove of wonderful tech and gadgets out there for the musically-minded. Here are our picks of the bunch, and ones that are sure to keep those feel-good music vibes flowing.
Pro-Ject Primary E Turntable
Turntables are back in fashion, and not just because retro is cool again. They're a great way to listen to music as god intended, with crisp, clear and booming sound quality. As far as first turntables go, the Pro-Ject Primary E is a great option and while it's fairly simple, it won't break the bank. It also comes highly recommended, and in a field dominated by cheap, hollow-sounding knock-offs, that quality means the world.
Twin Peaks Limited Edition Vinyl
It doesn't have to be Twin Peaks. Heck, it can be anything you want it to be, but if you're planning on forking out for a killer vinyl player, then you'd best include some killer vinyl with it, right? Or maybe your gift recipient already has a vinyl player, in which case, your gift can be a thoughtful addition to their vinyl collection. Think about what types of movies, TV or music that they like, and get something nice for them to fill their earholes with.
Nintendo Switch
A Nintendo Switch on a list of music items? You betcha. It probably wouldn't be the first thing that you think of, but the Nintendo Switch is home to some killer music apps, including a cardboard Nintendo Labo piano, which you can use to create and control your own tunes. There's even a strange little KORG gadget for Nintendo Switch, which you can purchase separately online. Who knew the Switch was a secret music making machine?
3 months of Spotify Premium
A Spotify gift card is the gift that keeps on giving for the music lover. Nobody wants to deal with an influx of ads, and this simple (and stress free) gift is a win-win for you and your giftee. There's nothing worse than travelling in a mates car and having your jams interrupted every half hour by a chirpy sing-song advertising voice. A Spotify gift card will help you both jam on, and on (or at least until the 3 months is up).
Sony WF-1000XM3
When Gizmodo Editor Tegan Jones reviewed these earbuds earlier in the year, she claimed that Sony must have sacrificed souls to Satan to make these buds as good as they are. That should give you an idea of their sound quality, sturdiness and versatility. For the discerning audiophile, you can't go past a solid and well-made headset as the perfect gift, and the Sony WF-1000XM3s are a great option if you've got more of a budget for gifts.
Alternatively, if your pal is more of an overear person, the Son's 1000XM3's are still the best in class for sound quality and noise cancellation of a year after their release. You can read our review here. They're also down to $369 now!
Silly music socks
Yes, we're suggesting you buy your music lover mate some socks. But not just any socks — silly music socks! Novelty socks make for a great and practical gift, and while a kid might look at you funny for gifting socks, adults will love you for it, trust us. The amount of socks adults wear through a year is phenomenal, band getting a funky sock boost at Christmas is sure to lift their spirits. Having the socks be music-themed is just an added bonus.
RØDE NTUSB Condenser Microphone
The RØDE NTUSB Condenser Microphone often tops the list of the best quality microphones on the market, and for good reason. It boasts studio-quality sound and crisp recording, making it perfect for streaming, podcasting and recording audio. If your gift recipient thinks they're in with a chance to be the next Björk, the gift of the microphone might be the first step in their superstar singing adventure.
Audio-Technica ATH-MSR7GM SonicPro
Sometimes, just sounding good isn't enough. Your music lover mate might want earphones that are stylish too. Well, this Audio-Technica headset is both, with booming sound quality and a sleek maroon finish to boot. At $199, it won't break the budget, and with a slew of impressive reviews,these fashion-forward earphones are a great way to go, gift-wise.
Ultimate Ears Wonderboom 2 Portable Speaker
The only thing better than listening to music with friends is listening to music with friends in the outdoors. The Wonderboom 2 portable speaker will help your musical mate's wildest dreams come true with killer sound in a handy little package. With this gift, you can spend the rest of your summer rockin' out by the beach and listening to some sweet tunes while you chill. Plus, this neat little package is reasonably packaged so you get a good deal of bang for your buck.
IKEA SYMFONISK table lamp with Wi-Fi speaker
The IKEA Symfonisk range is a wild, furniture-themed experiment that combines everyday life with music in an attempt to join the two harmoniously. It succeeds pretty well, and of the range, the Symfonisk table lamp with Wi-Fi speaker is the coolest and most appealing item. Combining a lamp with a speaker is just an awesome idea, and not only does it make for a stylish bedroom accessory, it also brings your tunes right where you want them.
With these gifts, you can keep those toes a-tapping and beats a-playing all throughout the summer. Bring on the good vibes.

We're going to build a simple real-time chat application using React Native. Follow the quickstart tutorial first if you haven't yet set up your machine to use Siphon.
Navigate to a suitable directory (anywhere is fine) and type the following command to create a new app:
You can call it anything you like, but for the rest of this tutorial we will refer to the app as chat-app.
A new directory containing the basic app template will be created on your local machine and the files will be pushed to our servers.
Open up the Siphon Sandbox app on your iOS device and tap the new app icon to run it.
We're going to alter the template app that we just created. Open up the file called chat-app/index.js in your favourite editor.
Lets add a minimal user interface ready for sending and receiving chat messages. Remove the contents of that file and paste in the following code:
{% include "docs/snippets/user-interface.html" %}Later we'll use a websocket to connect to the server and append incoming messages to the messages state, but for now the UI is going to look quite empty.
Save the file and push your changes to Siphon:
The app will reload itself and you should see something like this:
We're going to use the WebSocket class provided by React Native to send and receive chat messages.
First we will only log incoming messages to the console. Add these two methods to your App class definition:
{% include "docs/snippets/websocket.html" %}After the App component gets rendered, its going to open up a socket and start printing incoming messages to the console.
Open up a separate terminal window and leave it streaming the logs from your app:
Now save the file and switch back to the other terminal window to push the changes:
You should see some log output in the new terminal window. If there are other Siphon users currently chatting, you may see some incoming messages in the logs.
Let's make a small change so that incoming chat messages are displayed in the UI. Replace the definition of componentDidMount with this one:
{% include "docs/snippets/mutate-state.html" %}Push your changes and run the app in the sandbox:
Any incoming chat messages will now be displayed visually.
Lets hook up the <TextInput> component so that it broadcasts its contents to the chat server when we hit send.
Replace the empty definition of handleSubmit with this one:
{% include "docs/snippets/handle-submit.html" %}Now when you hit send, it sends the message across the websocket that we created earlier and then clears the contents of the <TextInput>.
Push your changes and open the app. It should look like this:
That's the end of the tutorial, thanks for following along.


VERTIGO's Last Laugh A film review by John Locke Copyright 1997 John Locke
Alfred Hitchcock took a certain prankster's liberty with his work, most notably, delighting the audience and, no doubt, himself with his unpredictable and amusing cameos. While aware of this, we still insist on separate Hitchcocks, the pleasingly wicked charmer and the serious artist, with never the twain conflicting. However, his cele- brated masterpiece Vertigo, recently re-released, exposes Jekyll and Hyde as the same man. The strange symmetry of the film subverts dra- matic structure to create a more elaborate joke, showing that Hitchcock had ulterior, even mischievous, motives to his direction.
 Scottie, the detective, slips down a steep roof to end up dangling from a flimsy rain gutter. The policeman attempts a rescue but instead falls to his death. The scene ends with the horrified Scottie left hanging by his fingers.
In the following scene, Scottie discusses his recuperation with Midge, an old friend, but his escape from the dangerous predicament of the prologue is never explained. Scottie's cane and references to his corset are evidence of unspecified physical injuries, but it's his psycho- logical injury, his vertigo, that entices our curiosity, strongly enough to allow incidental acknowledgment of his physical injuries to satisfy us, if indeed we question them at all. But on analysis Scottie's physical injuries seem disproportionate to the danger; his escape by no means a certainty. It appears unlikely he could have pulled himself up alone without the gutter tearing away from the building; and there was no one else on the roof to provide timely assistance. If he had dropped the six stories to the pavement--the same fall that killed the policeman--he would at least have broken bones.
The only further references to the accident are deliberately vague. Midge jokingly warns Scottie not to "go diving off another rooftop," an unrevealing exaggeration; Gavin Elster, the old acquaintance who hires Scottie to trail his wife, calls the accident "that thing in the paper." Since a means for Scottie's escape can be easily imagined, these would be petty observations were they not evidence of Hitchcock's imprecision. Not only is Scottie literally left hanging in the opening, the viewer, too, is "left hanging" by the subsequent lack of explanation. And that forms one side of the symmetry, the set up to Hitchcock's joke.
The remainder of the first half of the film is sustained by the mystery of Madeleine Elster's (Kim Novak) relationship to the long- departed Carlotta Valdez, and Scottie's falling in love with the seem- ingly haunted Madeleine. The section culminates with Madeleine's fatal fall from the Mission San Juan Bautista tower. The mystery unfolds to expose "Madeleine" as an imposter, Judy, hired by Gavin Elster to trick Scottie and allow the murder of the real Madeleine to go undetected. As has been widely discussed (and harshly criticized, particularly on Vertigo's original release), Hitchcock lays out these startling revelations midway through the film. The bold tactic breaks the formulaic structure we expect from a murder mystery, in which solutions always come at the end. It risks unsettling the viewer, particularly on an initial viewing of the film. However, by dispensing with formula, Hitchcock shifts the emphasis of the story from murder to character, a potentially deeper subject than the typical whodunit conundrum. Scottie's behavior and motivations replace the enigmatic "Madeleine's" as the focus of the story. "Madeleine" was strange, Scottie was earthbound; now they switch.
Back on his feet, Scottie's motivations are complex. He becomes obsessed with remaking one woman (Judy) in the image of another he believes dead ("Madeleine"). Can this really be love? we think. Or is Scottie infatuated with the appearance of women but blind to substance? Or does he seek the unattainable in order to perpetuate desire? In any case, Scottie's feelings are intense, his actions in remak- ing Judy, imperturbable. In the climax of the story, when Scottie finally discovers that Judy is "Madeleine" his choices become even harder to fathom. The woman he has labored to remake suddenly becomes, in the flesh, the woman he has idealized. If his profound desire is fantasy, will achieving the concrete destroy his feelings? Compounding the dilemma, the new Judy that Scottie discovers has treated him treacherously, subjecting him to the grief of lost love, the public humiliation of the inquest, and a nervous breakdown.
Against all this is the possibility they really love each other. Hitchcock sustains our curiosity for the outcome, and perhaps our hope for romance, by moderating Judy's character. Despite her likely guilt as an accomplice to murder, her moral failure may be less severe. In her narrated letter (and the accompanying flashback of the real Madeleine's plummet from the tower), we are left with the impression Judy did not realize murder would be the result of the scheme to trick Scottie. She appears genuinely shocked when Gavin throws Madeleine from the tower. Gavin must stifle her screams. Mitigating her responsibility in this way gives Scottie room to maneuver emotionally. If he can discover the truth, he may have grounds for compassion and forgiveness.
(These are the considerations of Scottie, betrayed lover. Additional questions arise about Scottie, the career lawman who once imagined becoming Chief of Police. Will he put his obsession above the law and overlook Judy's crimes? Will he jeopardize his innocence by keeping mum about the murder?)
The conditions are complicated, but Scottie has the freedom to make a choice. Indeed, the story accelerates toward the crucial moment in which he will shape his future and define his character. As Scottie and Judy struggle to the top of the tower, criminal and emotional deceits disintegrate in the heat of exploding truth. There is anger, yet passion. The time to choose has arrived. But, disappointingly, chance forestalls choice. The pair is startled by a nun ascending into the tower. Judy falls from Scottie's arms and out the tower to her death, depriving Scottie of his decisions.
Superficially, this conclusion provides some satisfaction, subjecting Scottie and Judy to like measures of poetic justice, the ironic working of fate, or some other intangible force. Scottie loses two loves to identical tragedies; Judy dies in the manner of the victim she helped murder. Assuming that Hitchcock did not structure the film as a joke, this interpretation would leave the conclusion in contradiction with the earlier direction of the film. In the long sequence in which Scottie trails "Madeleine," we are led to suspect some supernatural force--reincarnation, ghostly possession, perhaps--as motivating "Madeleine's" strange behavior. But the film disavows such forces by resolving the mystery with a rational explanation, grounding the story in the worldly realm where suspense more naturally results from the indeterminism of free will, as dramatized by Scottie's uncertain choices, rather than the possibility of some karmic comeuppance, irrelevant in its randomness. To fall back on fate after establishing the solitude of freedom would be a clear retreat.
The closing scene thus mirrors the opening, completing the symmetry. Again, we are "left hanging," this time by the inconclusive ending. The final shot strands us at a height, showing Scottie on the tower ledge staring down, stunned, to where Judy has fallen. The many interesting questions the film raises about Scottie's future will go unanswered. The double entendre of Hitchcock's opening scene, which ends with a rather similar shot, has set us up for a magnificent cop-out, warning us, in effect, of the film's method. On one level, Vertigo bewitches us with eery fascination; on another, it takes us on a wild goose chase in search of Scottie's essence, turning his heart into the ultimate MacGuffin.

This chapter describes wide-character string-handling functions and managing areas of memory containing wide characters. The corresponding declarations are in wchar.h.


Test if you have Ubuntu installed by typing “Ubuntu” in the search box in the bottom app bar that reads “Type here to search”. If you see a search result that reads “Ubuntu 18.04 LTS” with “App” under it, then you have it installed.
Enable-WindowsOptionalFeature -Online -FeatureName
Microsoft-Windows-Subsystem-Linux
whoami
followed by Enter at the prompt (it should print
your first name)
sudo apt update
(if prompted for your password, enter it)
sudo apt upgrade
(if prompted for your password, enter it)
Git comes with Ubuntu, so there’s nothing to install. However, you should configure it using the following instructions.
git config --global user.name "Your Name"
with replacing
“Your Name” with your real name.
git config --global user.email<EMAIL_ADDRESS>with
replacing<EMAIL_ADDRESS>with your real email.
Test if you have Chrome installed by typing “Chrome” in the search box in the bottom app bar that reads “Type here to search”. If you see a search result that reads “Chrome” with “App” under it, then you have it installed. Otherwise, follow these instructions to install Google Chrome.
Test if you have Node.js installed by opening an Ubuntu terminal and
typing node --version
. If it reports “Command ‘node’ not
found”, then you need to follow these directions.
sudo apt update
and press
Enter
sudo apt install build-essential
and press Enter
curl -o-
https://raw.githubusercontent.com/nvm-sh/nvm/v0.35.2/install.sh |
bash
and press Enter
. ./.bashrc
and press Enter
nvm install --lts
and press
Enter
node --version
and seeing it print something that is not
“Command not found”!
For your projects you will often have to download a zip file and unzip it. It is easier to do this from the command line. So we need to install a linux unzip utility.
In the Ubuntu terminal type: sudo apt install unzip
and press
Enter
Test if you have Mocha.js installed by opening an Ubuntu terminal and
typing which mocha
. If it prints a path, then you’re good.
Otherwise, if it prints nothing, install Mocha.js by typing
npm install -g mocha
.
Ubuntu does not come with Python 3. Install it using the command
sudo apt install python3
. Test it by typing
python3 --version
and seeing it print a number.
As of the time of writing of this document, WSL has an issue renaming or deleting files if Visual Studio Code is open. So before doing any linux commands which manipulate files, make sure you close Visual Studio Code before running those commands in the Ubuntu terminal.
The commands you need to enter are listed below. Here we will install basic developer tools, such as homebrew (a 3rd party package manager for MacOS), Xcode (a library of developer tools provided by Apple), VS Code (a full-featured text-editor), and Node (a JavaScript runtime environment).
Here at App Academy, our browser of choice is Google Chrome. This isn’t super important at the beginning of the course, but once we get into frontend development (writing code that runs in a web browser) the Chrome DevTools will be crucial for debugging every manner of issue.
To install Google Chrome, download the necessary files and follow the instructions on the Google Chrome website.
Let’s start with Xcode. The Xcode command line tools are a requirement for installing the homebrew package manager in the next step.
NOTE: If you are using a Linux machine you will not be able to install Xcode or homebrew.
Install the Xcode command line tools by running the following from the console.
$ xcode-select --install
To conclude the installation you will need to agree to the Xcode license. Start the Xcode app, click “Agree”, and allow the installation to finish. Then you can go ahead and quit the Xcode app.
Homebrew is kind of like a low-tech App Store. It allows us access to and the ability to install a wide variety of software and command line tools from the console. These are distinct from those hosted on the App Store and will need to be managed by Homebrew.
Enter the following in your terminal to download and install Homebrew:
/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
You will be given a list of dependencies that will be installed and
prompted to continue or abort. Press RETURN
to continue.
Let’s break this command down a bit. curl
, a command-line
tool commonly used for downloading files from the internet, is used to
download the Homebrew installation file. The
"$(...)"
transforms the file content into a string. Finally,
the string is passed to a Ruby language executable (/usr/bin/ruby
is where the system Ruby executable file is stored on our machine) with
the -e
flag to tell Ruby to run the argument as code.
Check out the Homebrew website to learn the basic commands.
Node.js is a very powerful runtime environment built on Google Chrome’s JavaScript V8 Engine. It is used to develop I/O intensive applications like video streaming sites, robots, and other general purpose applications. For our purposes Node provides a way for us to run JavaScript outside of the browser.
We want to use a version manager with Node to help us manage potential conflicts between versions and dependencies. In this case we will be using NVM (Node Version Manager) to install/manage Node.js.
Open up your console (the Terminal application on Mac) and run the following:
# download and run the official install script
curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.33.6/install.sh | bash
# update your terminal config (you will now have access to the nvm command)
source ~/.bashrc
# install a stable version of node
nvm install 10.16
# set version 10.16.0 as default version
nvm use 10.16
# verify install/config
which node # => /Users/username/.nvm/versions/node/v10.16.0/bin/node
Node comes with a package manager called NPM, which provides access to a whole ecosystem of libraries and tools we can use. NPM comes pre-bundled with Node, so there is no additional work for us to do. By default we don’t need any additional libraries, and any additional packages we do need to use will be installed on a project-by-project basis.
This one is pretty easy. Go to website for Visual Studio Code, then download and install VS Code.
To verify that the shell commands were installed correctly, run
which code
in your terminal. If code
is not a
recognized command, open the VS Code editor, open the Command Palette
(Cmd+Shift+P
on macOS ,Ctrl+Shift+P
on Linux)
and type shell command
to find the
Shell Command: Install 'code' command in PATH
command. Then
restart the terminal. This will now allow you to easily open files in VS
Code from the terminal using the code
command followed by a
file or directory.
Next, we’ll want to install a few useful VS Code extensions and configure
VS Code to play nice with these extensions. Download
this zip file, which contains a script that will do the work for you. Unzip the file
and navigate into the directory where the file is located in the terminal
(drag and drop the folder over to the terminal icon on macOS or right
click in the directory and select Open in Terminal
on most
Linux distributions).
To run the script, run the command:
./setup-vs-code.sh
The script will do the rest. Now restart VS Code and you’ll be good to go.
The last thing we’ll be installing will be Mocha. Mocha is a JavaScript
testing framework that we will be using to test our work in the future.
Here are the instructions of how to install mocha
!
npm install -g mocha
mocha --version
. If it returns a version number, you’ve
successfully installed mocha! Otherwise, let your instructor know and
they’ll help you fix things.
You can just use homebrew for this install, too.
brew install python


FREGE (Fundamentals of Reasoning for the Electronic Age) is a pair of introductory "courses":
-
Reasoning (Logic)
-
Discrete Mathematics (Sets, Relations and Functions)
FREGE's target audience is beginning computer science students, but the Reasoning course is also appropriate for students in other disciplines who want to learn the art of clear thinking.
Course materials include:
- An online "book", i.e., a collection of slides that present all the course material. No supplementary book is required.
- A large collection of problems that are integrated into the slides. These courses are sandboxes. Students don't just read they practice and experiment continuously.
- A collection of short videos.
- A collection of plugin apps that enable students to explore specific topics in a highly interactive way. See the menu at the left for links to those that can be accessed as standalone environments.
The current implementation of these courses uses the
Quest platform, designed and hosted at The University of Texas at Austin. Interactive proof construction and evaluation are provided by Querium.
Email us if you would like more information about FREGE.

These examples were used to discuss writing reusable charts in D3 by Michael Freeman at the Strata + Hadoop Singapore 2016 conference. All code is here.


So far, we've discussed applications that used only the Access Methods for fast data storage and retrieval. Application code that uses Berkeley DB in this way might appear as follows:
switch (errno = dbp->put(dbp, NULL, &key, &data, 0)) { case 0: printf("db: %s: key stored.\n", (char *)key.data); break; default: fprintf(stderr, "db: put: %s\n", strerror(errno)); exit (1); }
The underlying Berkeley DB architecture that supports this is:
As you can see from this diagram, the application makes calls into the Access Methods, and the Access Methods use the underlying shared memory buffer cache to hold recently used file pages in main memory.
The previous chapters in this Guide have described applications that use only the Access Methods. The subsequent chapters will describe how to build more complex applications that include full database recoverability. However, writing recoverable applications requires a small amount of additional complexity in the application, and quite a bit of additional complexity in the Berkeley DB library.
The additional complexity in the application is that calls to the Access Methods must be wrapped in transaction begin and end calls, i.e., the application must inform Berkeley DB where to begin and end transactions, and must be prepared for the possibility that it may not be possible to make a specific change to the database at any particular time (e.g., that the transaction can abort).
A typical example of transaction protected code might appear as follows:
retry: if ((errno = txn_begin(txnp, NULL, &tid)) != 0) { fprintf(stderr, "db: begin: %s\n", strerror(errno)); exit (1); }switch (errno = dbp->put(dbp, tid, &key, &data, 0)) { case EAGAIN: (void)txn_abort(tid); goto retry; case 0: printf("db: %s: key stored.\n", (char *)key.data); break; default: fprintf(stderr, "db: put: %s\n", strerror(errno)); exit (1); }
if ((errno = txn_commit(tid)) != 0) { fprintf(stderr, "db: commit: %s\n", strerror(errno)); exit (1); }
In this example, the same operation is being done as before, however, it is wrapped in transaction calls. The transaction is started with txn_begin, and finished with txn_commit. If the operation fails due to a deadlock, then the transaction is aborted using txn_abort, and the operation is retried from the beginning.
There are five major subsystems in Berkeley DB: the Access Methods, the Memory Buffer Pool, Transactions, Locking and Logging.
Here is a complete picture of the Berkeley DB package:
The application makes calls to the Access Methods and to the Transaction subsystem. The Access Methods and Transaction subsystem make calls into the Buffer Pool, Locking and Logging regions on behalf of the application.
While each of the underlying subsystems (Lock, Log and Buffer Pool) can be called separately (e.g., the Buffer Pool subsystem can be used apart from the rest of Berkeley DB by applications simply wanting shared memory buffer pool functionality), most applications will either use the Access Methods only, or the Access Methods wrapped in calls to the Transaction interfaces if they need database recoverability in the face of application or system failure.


Chapter 1 Overview and Introduction {#Overview and Introduction}

Random allocation of treatment to units (individuals or clusters) is perhaps the single strongest design tool we have in epidemiology and clinical research to estimate the causal effect of a treatment on outcomes. Randomization ensures that individuals who receive treatment are, on average, exchangeable with those who do not [1]. Without randomization, individuals who seek or receive treatment are almost inevitably different from those who do not, often in immeasurable ways. This leads to confounding of the treatment-outcome relationship.
Importantly [1]:
“The term random does not mean the same as haphazard but has a precise technical meaning. By random allocation we mean that each patient has a known chance, usually an equal chance, of being given each treatment, but the treatment to be given cannot be predicted.”
In practice, generating an allocation sequence involves the following steps:
| Steps | |
|---|---|
| 1 | Finalize the study design and randomization plan, including specifics about allocation ratio, any blocking/stratification, and masking. |
| 2 | Create a randomization subdirectory within the trial’s project directory to save the randomization files. If randomization is masked, you will need to save the randomization files in a separate, tightly controlled directory (sync’d to the cloud for secure backup). |
| 3 | Write a script to generate a random sequence. If the trial is masked, use temporary letters. |
| 4 | Assess randomization diagnostics to ensure that the randomization sequence behaves as expected. |
| 5 | Share the randomization sequence and diagnostics with the PI and trial’s biostatistician. Have at least 2 people review the randomization script and diagnostics to check for any errors. |
| 6 | If the trial is masked, work with the trial’s unmasked biostatistician to assign the final letters to each treatment group using the agreed upon, private mapping between letters and treatment group. |
| 7 | Set a new seed, and generate the final sequence. Store the sequence in a .csv file in the randomization directory and lock the file to ensure it cannot be over-written. |
This short guide will cover details for each step, and will elaborate in some areas where appropriate (e.g., providing examples of how to generate stratified or blocked sequences).
