1. Basic functions
1.1. Implement user request processor (UserProcessor)
We provide two types of user request processors: SyncUserProcessor and AsyncUserProcessor.
The difference between them is that the former returns the processing result in the form of a return value in the current processor thread, while the latter has an AsyncContext stub and can call the sendResponse
method in the current thread or an asynchronous thread to return the processing result. For examples, refer to the following two types:
1.2 Implement connection event processor (ConnectionEventProcessor)
We provide two connection event processors: ConnectionEventType.CONNECT and ConnectionEventType.CLOSE. You can create your own event processors and register them with the client or the server. The client side and server side can each monitor both of their connection and disconnection events.
1.3 Client side and server side initialization (RpcClient, RpcServer)
We have provided an RpcClient and RpcServer. They can be used after going through a simple initialization of necessary functions, or after switching on the functions. The most simple example is as follows:
1.4 Basic communication model
We have provided four types of communication models:
1. Oneway calls
The current thread initiates a call that is not interested in the call result and is not subject to timeout control. As long as the request is sent out, the call is completed. Note: Oneway calls are not guaranteed to succeed, and the initiator of the call has no way of knowing its result. For that reason, these calls are usually used in scenarios that can be retried or that have fixed-time notifications. Network problems or machine malfunctions during the call process may result in failure. This kind of call should only be used in business scenarios that accept such exceptions. For more information, see Example.
2. Sync calls
The current thread initiates a call that only completes if it receives a result within the set timeout time. If a result is not received within the timeout time, it will generate a timeout error. This is the most commonly used call type. Ensure that the timeout time is set reasonably in accordance with the opposing terminal’s processing capacity. For more information, see Example.
3. Future calls
The current thread initiates a call and can then move onto executing the next call after getting an RpcResponseFuture object. The get() method of the RpcResponseFuture object can be used at any time to get the result. If the response has already been returned, the result can be acquired straight away. If the response has not been returned yet, the current thread is blocked until the response is turned or the response times out. For more information, see Example.
4. Callback asynchronous calls
The current thread initiates a call and it immediately ends, allowing the execution of the next call. A callback needs to be registered when the call is initiated. This callback must be assigned an asynchronous thread pool. After waiting for a response to come back, the callback logic will be executed in the callback’s asynchronous thread pool. For more information, see Example.
1.5 Print logs
SOFABolt only depends on SLF4J as the logging facade. Three types of log template are available: log4j, log4j2, and logback. Users only need to depend on one type of log implementation during run-time. The sofa-common-tools component that we are relying on will dynamically sense which type of log implementation is being used during run-time. It will load the correct log template and print. The log is printed and saved under the ~/logs/bolt/
directory, and following types of logs are included:
- common-default.log: The default log. Prints ordinary logs from the communication process, such as those relating to the client side and server start-up/shut-down.
- common-error.log: The exceptions log. Prints framework operation errors.
- connection-event.log: The connection event log
- remoting-rpc.log: The log related to the RPC protocol
For log dependencies, refer to Log implementation dependencies.
2. Advanced functions
2.1 Request context
During the call process, we provide the InvokeContext API and pass it down. It can be acquired from the custom serializer and user request processor. We call context based on two scenarios:
- Client-side: The user can set some parameters valid for this request, such as serializer type or whether CRC (or other mechanisms) is enabled. At the same time, they can acquire information from the context like the time taken to establish a connection, connection information, etc.
- Server-side: The user can acquire the queuing time after the request arrival, connection information, and other such information from the user request processor.
- Note: The contexts of the client side and server side are independent. That is to say, the context set on the client side is only visible on the client side, and vice versa.
- Examples
2.2 Duplex communication
In addition to the server side being able to register user request processors, our client side can also register user request processors. When registered, the server side can initiate calls to the client side. It can also use 1.4 to refer to any type of communication model.
- Sample 1: Use the Connection object’s duplex communication . Note: When using the Connection object’s duplex communication, the server side needs to save the Connection object through the event monitoring processor or the user request processor.
- Sample 2: Use the Address duplex communication . Note: When using the address method’s duplex communication, when you initialize the RpcServer, enable manageConnection to indicate that the server side will maintain the mapping relationship between an address and the connection according to the connection initiated by the client side. When duplex communication is not needed by default, this function is disabled.
2.3 Establishing multiple connections and connection warm-up
Generally speaking, for point-to-point direct communication, or client side to server side, one IP to one connection object is sufficient. In terms of anything from throughput to concurrency, standard business communication needs can all be met. But there are other scenarios, such as non-P2P communication that goes through LVS VIP or F5 device connection instead, where fault tolerance and load balancing require establishing multiple connections for a single URL. The method below establishes multiple connections. When initiating the call, it adds the following parameter to the transmission URL: <IP_ADDRESS>:12200? CONNECTIONNUM=30&_CONNECTIONWARMUP=true
, indicating that this IP address needs the establishment of 30 connections, and the connections need to be warmed up. The difference between warmed up and not warmed up:
- Warmed up: The first time it is called (e.g. Sync synchronous call), 30 links are established.
- Not warmed up: Every time it is called, it creates one connection until 30 have been established.
- Examples
2.4 Automatic disconnection and reconnection
In the process of the RPC call, there is not usually disconnection or reconnection. This is because during every RPC call, it will check whether there is a usable connection, and if there is not, it will establish a new one. But in some scenarios, disconnecting and maintaining long connections are required:
- Automatic disconnection: For example, when establishing multiple connections through LVS VIP or F5, because of the network device’s load balancing mechanism, some connections might be fix-mapped to the RS of several back ends. At this point, they need to disconnect and reconnect, relying on the randomness of the connection establishment process to implement the final load balancing. Note: In scenarios where automatic disconnection is enabled, it normally has to be used in cooperation with reconnection.
- Reconnection: For example, after the client side initiates connection establishment, the server side sends a request to the client side through duplex communication. If there is no reconnection mechanism at this time, it cannot be implemented.
- Use case. Remember to take into consideration that a process may have multiple SOFABolt communication instances. We have provided a global switch and user switch as the two different activation methods:
//Turn on or off through system attributes. If a process has multiple RpcClient, they take effect simultaneously.
System.setProperty(Configs.CONN_MONITOR_SWITCH, "true");
System.setProperty(Configs.CONN_RECONNECT_SWITCH, "true");
//Turn on or off through the user switch. Only the current RpcClient instance is affected.
client.enableReconnectSwitch();
client.enableConnectionMonitorSwitch();
2.5 Serializer and deserializer
For the default serializer and deserializer, we currently recommend using Hessian. But considering the needs of different scenarios, we support the extension of the default serializer and the custom serializer’s functional characteristics.
- Serializer extension: Implement an inherited serializer, then register and assign an index through SerializerManager. Sample code:
// 1. Implement Serializer
public class HessianSerializer implements Serializer {
@Override
public byte[] serialize(Object obj) throws CodecException {
...
}
@Override
public <T> T deserialize(byte[] data, String classOfT) throws CodecException {
}
}
// 2. Register
public static final byte Hessian2 = 1;
SerializerManager.addSerializer(Hessian2, new HessianSerializer());
// 3. Set validity through system attributes
System.setProperty(Configs.SERIALIZER, String.valueOf(Hessian2));
- Custom serializer: Implement a CustomSerializer type. Custom serializer and deserializer can be applied to Header and Content. At the same time, we have provided InvokeContext on the API, so the logic of the serializer and deserializer can be dynamically adjusted according to the request context.
- Example
3. Advanced functions
3.1 Enable I/O thread processing mechanism
By default, we use the thread model in the best practice to process requests, that is, occupying I/O threads as few as possible. But in some scenarios, such as when the computing process is simple, you may want to reduce thread switching and increase I/O throughput as much as possible. In these cases, we have provided a switch to allow business processing to be executed on the I/O thread.
3.2 Enable user processor multi-thread pool mechanism
In request processing, there is one thread pool by default. When a fault occurs on the thread pool, the overall throughput will decrease. But in some business scenarios, an individual thread pool needs to be allocated to the core request processing. In this way, interference between different requests can be avoided. Thereby, we have provided a thread pool selector.
- Implement a thread pool selector. [Example]
- Then install it in the user request processor. During the calling process, it can select the corresponding thread pool based on the selector’s logic. [Example]
3.3 Request process timeout FailFast mechanism
After the server side receives a request, if the waiting time of the thread pool queue exceeds the timeout time of the client side upon calling initiation, then the calling can be discarded because it is no longer of use to the client side. (Note: this mechanism does not apply to the one-way calling method because it does need a timeout time to be set.) By default, this function is enabled. However, as users may need to make their own judgments about whether to discard requests, and at the same time print out logs to make records, we have provided a switch to control this function:
- Switch control
@Override
public boolean timeoutDiscard() {
return false;// true indicates automatic discarding being enabled; false indicates automatic discarding being disabled. Users can determine by themselves later in the processor
}
- Determine timeout and print the log
public class SimpleClientUserProcessor extends SyncUserProcessor<RequestBody> {
@Override
public Object handleRequest(BizContext bizCtx, RequestBody request) throws Exception {
if(bizCtx.isRequestTimeout()){
log.info("arrive time: {}", bizCtx.getArriveTimestamp());
...
}
}
}
3.3 Customize protocols
In scenarios where communications are relatively simple, we use the RPC communication protocol. Using the corresponding communication type can solve most problems. But in some scenarios, such as with information middleware, database middleware, etc., they have their own private communication protocols, and the bulk of request command types in such scenarios need to redefine their protocols. In these scenarios, SOFABolt is used as a protocol framework and as a component with basic communication functions, like base communication model and connection management functions, etc., which can be reused. For protocol-related parts that you need to develop and implement yourself, refer to the RPC protocol implementation content. [Example].


Any application that can be written in JavaScript, will eventually be written in JavaScript.

JS was invented 17 years ago. The same year:
... But debugging difficulty is related to complexity.
Do you debug your JavaScript by adding code like this?
alert(foo);
There's no shame in this... In fact, it resembles:
<cfdump var="#foo#" />

The part that you've all been waiting for...
Pre-req: Everyone knows about console.log, right?
console.log(foo);
May you never alert()
again!
In any dev-tools tab other than the console,
hit Esc to open a mini-console.
console.log()
takes multiple arguments.
Label your debug output!
console.log('foo:', foo);
//also handy!
console.info('info:', foo);
console.warn('warn:', foo);
console.error('error:', foo);
console.assert(false, 'my assertion');
console.time('myTimer');
for (var i=0; i<100; i++){ console.log(i); }
console.timeEnd('myTimer');
Similar to jQuery DOM selection, but without jQuery.
$$('li');
Jump to DOM node in Elements panel from console
inspect( $$('li')[0] );

The console can only interact with one page. If you've got a frameset or iframe to deal with, it can feel troublesome.
cd(window.frames['frameName']);

Let’s write books in HTML! HTMLBook is an open, XHTML5-based standard for the authoring and production of both print and digital books. HTMLBook is built on the following premises:
As such, HTMLBook can be characterized in the following ways:
Requirements for HTML5 elements in the HTMLBook specification are below. Special semantic inflections for data-type
attributes, unless otherwise noted, come from EPUB 3 Structural Semantics Vocabulary
Many content models refer to “Block Elements” or “Inline Elements”; please see Block Elements and Inline Elements for the corresponding list of HTML5 elements that belong to each of these categories.
If no content model or attribute requirements are explicitly specified, then HTMLBook adopts the corresponding requirements in the [[!HTML5]] Specification
data-type
for specifying book-specific semantics instead of class
. The class
attribute is
now free to be used for whatever user-defined semantics are desired, and there are no restrictions on class
values. Users of the spec may want to replicate data-type
values in the class
attribute to facilitate CSS styling, but this is completely optional.HTML element:
Attribute requirements: data-type="book"
(Not in [[EPUB3SSV]]; from [[DOCBOOK]])
Content model: Optional

that contains book title, or Header block that contains book title and optional subtitle content; then one or more Book Component elements as children (

for Part elements,
for Table of Contents, and

elements for all other book divisions)
Example

of "glossary"
, with

children with a data-type
of "glossterm"
and

children with a data-type
of "glossdef"
. Term text should be wrapped in a <dfn>

is used for

elements nested directly in main Book Components ("chapter"
, "appendix"
, etc.). sect2
is used for

elements nested in a sect1

, sect3
is used for

elements nested in a sect2

, and so on.
Content model: The first child must either be a main heading element corresponding to the hierarchy level indicated by data-type
value, as follows:
"sect1" -> h1 "sect2" -> h2 "sect3" -> h3 "sect4" -> h4 "sect5" -> h5
or a Header block that contains section title and optional subtitle content. This is followed by zero or more Block Elements, followed by zero or more

Ruby: Enumerable Methods
December 10, 2015
This week we got to have some more practice with Ruby. We learned how to modify arrays and strings with methods, and store more complex information with hashes. We also learned about object classes and how each class has specific methods that can be applied to them. From there, we learned how to make our own classes and how to define methods that could be used for them. Two of the methods I learned about were each, and map.
The each and map methods are very similar. They're both iterators, and they apply a block of code to each item in the object that they're being applied to. Their main difference is what happens after the block is done running. With the each method, after the block runs, it will return the original object without storing the block's results, but is usually used for its side effects. If you want to run the each method and you want to use the index of each element of the object as a factor in your results, you could use the method, each_with_index. The map method will return an array filled with the results of the block of code that's being applied to the object. Map can also be used as collect, as they have the same effect.
This is an example of using the "each" method:
This is an example of using the "map" method:
Notice how when using each, if you want to see the results of the method, you have to use a printing method, and then have the original array returned. When using map, the results of the method are returned without having to apply another block of code. This is a clear illustration of the difference between the two methods. While they are both iterators, each is used for its side effects, and map is used for its results.

public class DefaultPartitionCoalescer extends Object implements PartitionCoalescer
prev
) into fewer partitions, so that each partition of
this RDD computes one or more of the parent ones. It will produce exactly maxPartitions
if the
parent had more than maxPartitions, or fewer if the parent had fewer.
This transformation is useful when an RDD with many partitions gets filtered into a smaller one, or to avoid having a large number of small tasks when processing a directory with many files.
If there is no locality information (no preferredLocations) in the parent, then the coalescing is very simple: chunk parents that are close in the Array in chunks. If there is locality information, it proceeds to pack them with the following four goals:
(1) Balance the groups so they roughly have the same number of parent partitions (2) Achieve locality per partition, i.e. find one machine which most parent partitions prefer (3) Be efficient, i.e. O(n) algorithm for n parent partitions (problem is likely NP-hard) (4) Balance preferred machines, i.e. avoid as much as possible picking the same preferred machine
Furthermore, it is assumed that the parent RDD may have many partitions, e.g. 100 000. We assume the final number of desired partitions is small, e.g. less than 1000.
The algorithm tries to assign unique preferred machines to each partition. If the number of desired partitions is greater than the number of preferred machines (can happen), it needs to start picking duplicate preferred machines. This is determined using coupon collector estimation (2n log(n)). The load balancing is done using power-of-two randomized bins-balls with one twist: it tries to also achieve locality. This is done by allowing a slack (balanceSlack, where 1.0 is all locality, 0 is all balance) between two bins. If two bins are within the slack in terms of balance, the algorithm will assign partitions according to locality. (contact alig for questions)

java.lang.Object net.parallaxed.bluejam.Individual
public class Individual
This class defines an individual. Also could be termed a chromosome in GP, but our individuals represent instances of NoteTrees based around a given Heuristic present in the population. An individual implements Function in the sense that it has access to the "play()" function in the NoteSequence represented by the individual. Theoretically, this permits individuals and their sequences to be chained together.

Asos appoints first chief growth officer
by Jessica ClarkAsos has appointed its first chief growth officer to strengthen its senior management team as it recovers from a drop in profit following a botched international expansion.
The online retailer said Robert Birge, who was previously chief marketing officer at travel search site Kayak and media agency IMG, will join the company on 3 December.
Read more: Asos doubles down on Black Friday after poor trading last year
Asos pledged to strengthen its executive team when it announced plunging profit in its full-year results in October.
The drop followed major problems at its new warehouses in Berlin and Atlanta as the retailer targeted international expansion.
The e-commerce giant is currently in the process of recruiting three other new executives to oversee its product, HR and strategy divisions.
Asos chief executive Nick Beighton said: “Robert’s proven track record in delivering high impact marketing programmes for fast-growing e-commerce businesses means he is an ideal appointment for this new role.
“And, with more than half of our revenue coming from international markets, his global experience will help fuel our ability to take advantage of the growth opportunities ahead of us.”

Birge added: “I am incredibly excited to be joining Asos. Its world-class brand and recent infrastructure investments mean it is well placed to accelerate its global growth plans, and I can’t wait to join the team and play my part.”

Running Puma in Rails Development Mode
"Loopback requests"
Be cautious of "loopback requests," where a Rails application executes a request to a server that, in turn, results in another request back to the same Rails application before the first request completes. Having a loopback request will trigger Rails' load interlock mechanism. The load interlock mechanism prevents a thread from using Rails autoloading mechanism to load constants while the application code is still running inside another thread.
This issue only occurs in the development environment as Rails' load interlock is not used in production environments. Although we're not sure, we believe this issue may not occur with the new zeitwerk
code loader.
Solutions
1. Bypass Rails' load interlock with .permit_concurrent_loads
Wrap the first request inside a block that will allow concurrent loads: ActiveSupport::Dependencies.interlock.permit_concurrent_loads
. Anything wrapped inside the .permit_concurrent_loads
block will bypass the load interlock mechanism, allowing new threads to access the Rails environment and boot properly.
Example
response = ActiveSupport::Dependencies.interlock.permit_concurrent_loads do
# Your HTTP request code here. For example:
Faraday.post url, data: 'foo'
end
do_something_with response
2. Use multiple processes on Puma
Alternatively, you may also enable multiple (single-threaded) workers on Puma. By doing so, you are sidestepping the problem by creating multiple processes rather than new threads. However, this workaround is not ideal because debugging tools such as byebug and pry, work poorly with any multi-process web server.

Communication strategies
Communication in the RIS3 process is a part of Governance Phase but it’s especially important in this phase. This is because vision creation is all about motivating and including all stakeholders. Nonetheless, communication is a crucial part of the whole process and should be assessed in all RIS3 Phases.
The communication strategy should include at least these elements:
- Communicating the regional RIS3 process as a part of national and European contexts
- Engaging the target stakeholders
- Informing the public about the need to support the development of knowledge-based businesses in the region
All regional stakeholders (SMEs, high-tech companies, universities, transfer institutions, local and regional authorities, the media etc.) have different expectations of the RIS3 process. Thus, it’s important to get them to contribute to the process from their perspective.
Appropriate communication methods and the communicated content should be selected so that they concern the target stakeholders and are relevant to them.
The RIS3 process should be made visible to the public through its own brand. Hence, there should be at least following coherent communication tools:
- Logo, supporting the regional identity and innovation
- Web pages that are attractive and informative, also in English
- Newsletters and leaflets
- Publications on certain parts of the process (for example key analyses and peer reviews)
- Conferences and seminars, the region should also participate in international RIS3 conferences
- Press and TV campaigns
The content of these mediums should include priorities, strategic lines and demonstration of pilot projects.
Active communication tools are proactive in nature and always in anticipation of something.
- Targeted visits to stakeholders
- Joint workshops and seminars
- Visiting sites
- Press conferences
- Roundtable discussions
- Meetings with local and regional politicians
Conferences and seminars can be used in different stages of the project
- In the beginning: Launch conference brings awareness of the project to stakeholders and stimulates participation. The primary message of the launch event should be well planned.
- In the middle: Conferences in the middle stimulate participation in constructing the strategy and validating analyses done during the process.
- In the end: End conference is necessary because all stakeholders are meant to commit to the strategy and implement it in their areas of activity.

My opinion, WWE wrestler AJ Styles is the best preformer in the western hemisphere. His career is has quite long, from the indy scene, to carrying the TNA brand, a wrestling promotion not as big as WWE but on television, to being the best American born wrestler in Japan and now the most exciting thing on WWE Televsion.

A distributed revision control and source code management (SCM) system with an emphasis on speed, data integrity, and support for distributed, non-linear workflows.
* However, GitHub is the reason we are all using git today
git log
- e.g. git log -2 -w -p origin/master^
~/.gitconfig
In general, everything that you use to refer to an object (checkin/branch/tag/etc) in git is a reference into the giant tree of commits. Some implications of this:
* ff2f4cd | (HEAD, foo) checkin some even better stuff (2 minutes ago) (Shawn Zeller)
* 4ba0f66 | checkin some great stuff (2 minutes ago) (Shawn Zeller)
* 337330e | (origin/develop, develop) restore /registry since that seems to be what we use for the health check (4 days ago) (Shawn Zeller)
* d778846 | merge autoZK to dev (8 days ago) (austin chau)
|\
| * a205cc4 | use latest debian plugin (8 days ago) (austin chau)
git diff -w cd78ce87e1a HEAD main.coffee
git branch a/cool/branch/name cd78ce87e1a
git filter-branch -f --index-filter 'git rm --cached --ignore-unmatch *.deb' --prune-empty --tag-name-filter cat -- --all
git filter-branch --prune-empty --subdirectory-filter some_cool_folder master
git push heroku master
History of shared working brances should be treated as immutable once your commits have been shared. Feature/working branches allow for:
* ff2f4cd | (HEAD, foo) checkin some even better stuff (2 minutes ago) (Shawn Zeller)
* 4ba0f66 | checkin some great stuff (2 minutes ago) (Shawn Zeller)
* 337330e | (origin/develop, develop) restore /registry since that seems to be what we use for the health check (4 days ago) (Shawn Zeller)
git reset --hard HEAD^
git reset HEAD^
git reset develop
git add .
git commit -m "all my stuff"
* 337330e | (origin/develop, develop) restore /registry since that seems to be what we use for the health check (4 days ago) (Shawn Zeller)
* d778846 | merge autoZK to dev (8 days ago) (austin chau)
|\
| * a205cc4 | use latest debian plugin (8 days ago) (austin chau)
Pull another working tree into your tree. Essentially does the following:
Note: In the case of trivial merges, git updates the current branch to simply reference the HEAD commit for the branch to merge.
Warning: Running git merge with non-trivial uncommitted changes is discouraged: while possible, it may leave you in a state that is hard to back out of in the case of a conflict.
What this really means is that reverting merge commits is a pain. Also, it makes unraveling the history of the repo, equally painful.
So, Shawn, what should we do to manage all of these branches that you tell us to have?
Forward-port local commits to the updated upstream head
Like many git commands, you can use rebase for a lot of things. However, there are two main uses for rebase.
pick 2cad4d7 add some entries to .gitignore pick 337330e restore /registry pick 4ba0f66 checkin some great stuff pick ff2f4cd checkin some even better stuff # Rebase ac0b6a7..ff2f4cd onto ac0b6a7 # # Commands: # p, pick = use commit # r, reword = use commit, but edit the commit message # e, edit = use commit, but stop for amending # s, squash = use commit, but meld into previous commit # f, fixup = like "squash", but discard this commit's log message # x, exec = run command (the rest of the line) using shell # # These lines can be re-ordered; they are executed from top to bottom. # # If you remove a line here THAT COMMIT WILL BE LOST. # # However, if you remove everything, the rebase will be aborted. # # Note that empty commits are commented out
You have a feature branch named foo branched off of master.

BloodHound requires three sets of information from an Active Directory environment in order to function:
- Who is logged on where?
- Who has admin rights where?
- What users and groups belong to what groups?
- (Optionally) What principals have control over other user and group objects?
In most instances, collecting this information does not require Administrator privileges, and does not require executing code on remote systems. The PowerShell ingestor, based on PowerView, makes data collection fast and simple. The ingestor is located in the BloodHound repo at /PowerShell/BloodHound.ps1.
PowerShell execution policy
PowerShell by default will not allow execution of PowerShell scripts; however, bypassing this restriction is very simple in most instances. Typically you will be able to enter a PowerShell runspace without this restriction by running:
PS C:\> PowerShell -Exec Bypass
For more options, see this great blog post from NetSPI on 15 different ways to bypass PowerShell execution policy.
Data Ingestion
We currently have two methods of ingesting data into BloodHound:
The PowerShell ingestor
CSV ingestion via the BloodHound interface

Born and raised in Korea, lived 2/3rd of my life here in beautiful WA. I've made a tough mid-life career pivot to get back to what I love, back to when I was a kid totally enchanted by a 386DX2 MS-DOS system with 4mb RAM and a handful of 5" floopy disks. I needed to get back to that special place where I get lost in problem solving, trouble shooting and increasing my technical skills that leads to more empowerment. Diving deep head first and flexing my creativity to fight for something and bring tangible changes to the world. And most importantly, having FUN while doing it.

Connecting an eGPU to a MacBook For Deep Learning
GPUs in Deep Learning
There is a large market in businesses today built on the advancements in machine learning and artificial intelligence. With the developments in the algorithms and models that drive these concepts, a parallel use and development of the hardware to run and train these models is ongoing.
Researchers and those working on deep learning side of ML and big data related competitions often invest in graphics processing units to accelerate their work flow. These GPUs are built to handle parallel computation of tensors, or high dimensional matrices. When working on research utilizing these deep learning models, I decided to invest in one.
Obtaining a Setup
When choosing a GPU, there are many factors for which one works best for you, and are covered very well by Tim Dettmers. I eventually chose a Nvidia Titan X, which had more than enough memory and bandwidth to run today’s deep learning models.
The second task was deciding how to set it up. Since I commute often, I didn’t want to invest in building a full computer setup. So the only other possibility was to find a way to hook up by GPU to the MacBook that I own externally. In this market there are not too many options, with the most common solution being a PCIe to Thunderbolt board.
There are a few companies that manufacture these solutions intended to host typical PCIe cards such as RAID cards or video capture cards, but don’t supply enough power to run a GPU by default. Most people are able to take apart these platforms to add their own power supply and PCIe riser to overcome the power limit. Since I didn’t want to spend too much time tinkering with the hardware, I opted for a pre-built solution by Bizon.
Compatibility
When I received my PCIe box, I was concerned that It would take a while to configure OSX with driver modifications. I also was questioning if it would work with Theano, a tensor python library I am writing my code with.
In terms of drivers, there setup was much easier than expected, as goalque already wrote a script that detected the card, pulled the drivers from Nvidia and changed the appropriate IOPCI tunnelling files. When I rebooted the card was recognized!
The reason why most people use Nvidia cards to run these sort of computations is due to CUDA. CUDA, proprietary to Nvidia, allows users to directly run code directly on the GPU. Many languages and packages targeted towards deep learning have integrated their libraries with CUDA to let users run demanding code on GPUs in the comfort of high level languages such as Python or Lua. Nvidia’s cuDNN also optimizes many of the operations that occur during machine learning and have been utilized by libraries, such as Theano, as well. I then continued by installed CUDA (I recommend using the full installation for those who just started) and cuDNN (you need to make a free developer account).
Performance Restrictions
While having a portable setup is nice, I knew that there were going to be some restrictions. Since the card was running off of a thunderbolt connections, there are possibilities for bottlenecks, as Thunderbolt 2 maxes out at 2.5 GB/s. From the system configuration above, we actually see that the card is running on PCIe at x4. Since thunderbolt 2 only supports PCIe 2 would usually be able to transfer at 2 GB/s, which for better or for worse within our theoretical bandwidth (You can argue that once you load in the data it wouldn’t matter much after that point).
Video cards get hot, especially with the stock cooler that comes with the Titan X. Usually decent radiators and cooling systems inside PCs can mitigate this problem. Since my box doesn’t have any additional cooling, If I run the card for extended periods of time, which I hope to when training my models, I’m going to expect some extra thermal throttling, and thus a reduction in clock speeds.
Performance Tests
Regardless of the potential speed and thermal issues, I was quite pleased by how the card performed. Running convolutional_mlp, I was able to get a 45-50x speedup.
Running some synthetic benchmarks (I might test and post other ones in the future), I got about the same score as a Titan X would in a rig (could be in the margin of error due to different CPUs, PCIe configs, RAM, etc.).
Finally when testing out my personal code, after adjusting some of the CUDA and Theano global variables, I got it to work smoothly. From the different models I was testing, MLP, CNN, RNN, I was able to get around a 23-30x speedup from the i7-4870HQ in my MacBook to the Titan X.
So far these test have been relatively superficial, so I’m going to run some larger models with larger batch data sizes that I’m working with and maybe I can find other positive and negative aspects as I go along. I want to eventually also test this setup against other common large models with Alexnet and Google LeNet to see how these variables affect model training performance.

astropy.io.ascii is able to write ASCII tables out to a file or file-like object using the same class structure and basic user interface as for reading tables.
The write() function provides a way to write a data table as a formatted ASCII table. For example:
>>> from astropy.io import ascii
>>> x = np.array([1, 2, 3])
>>> y = x ** 2
>>> ascii.write([x, y], 'values.dat', names=['x', 'y'])
The values.dat file will then contain:
x y
1 1
2 4
3 9
All of the input Reader table formats supported by astropy.io.ascii for reading are also supported for writing. This provides a great deal of flexibility in the format for writing. The example below writes the data as a LaTeX table, using the option to send the output to sys.stdout instead of a file:
>>> ascii.write(data, sys.stdout, Writer=ascii.Latex)
\begin{table}
\begin{tabular}{cc}
x & y \\
1 & 1 \\
2 & 4 \\
3 & 9 \\
\end{tabular}
\end{table}
The input table argument to write() can be any value that is supported for initializing a Table object. This is documented in detail in the Constructing a table section and includes creating a table with a list of columns, a dictionary of columns, or from numpy arrays (either structured or homogeneous). The sections below show a few examples.
An AstroPy Table object or a NumPy structured array (or record array) can serve as input to the write() function.
>>> from astropy.io import ascii
>>> from astropy.table import Table
>>> data = Table({'a': [1, 2, 3],
'b': [4.0, 5.0, 6.0]},
names=['a', 'b'])
>>> ascii.write(data, sys.stdout)
a b
1 4.0
2 5.0
3 6.0
>>> data = np.array([(1, 2., 'Hello'), (2, 3., "World")],
dtype=('i4,f4,a10'))
>>> ascii.write(data, sys.stdout)
f0 f1 f2
1 2.0 Hello
2 3.0 World
The output of astropy.io.ascii.read is a Table or NumPy array data object that can be an input to the write() function.
>>> data = astropy.io.ascii.read('t/daophot.dat', Reader=astropy.io.ascii.Daophot)
>>> astropy.io.ascii.write(data, 'space_delimited_table.dat')
A list of Python lists (or any iterable object) can be used as input:
>>> x = [1, 2, 3]
>>> y = [4, 5.2, 6.1]
>>> z = ['hello', 'world', '!!!']
>>> data = [x, y, z]
>>> ascii.write(data, sys.stdout)
col0 col1 col2
1 4.0 hello
2 5.2 world
3 6.1 !!!
The data object does not contain information about the column names so Table has chosen them automatically. To specify the names, provide the names keyword argument. This example also shows excluding one of the columns from the output:
>>> ascii.write(data, sys.stdout, names=['x', 'y', 'z'], exclude_names=['y'])
x z
1 hello
2 world
3 !!!
A dictionary containing iterable objects can serve as input to write(). Each dict key is taken as the column name while the value must be an iterable object containing the corresponding column values.
Since a Python dictionary is not ordered the output column order will be unpredictable unless the names argument is provided.
>>> data = {'x': [1, 2, 3],
'y': [4, 5.2, 6.1],
'z': ['hello', 'world', '!!!']}
>>> ascii.write(data, sys.stdout, names=['x', 'y', 'z'])
x y z
1 4.0 hello
2 5.2 world
3 6.1 !!!
The write() function accepts a number of parameters that specify the detailed output table format. Different Reader classes can define different defaults, so the descriptions below sometimes mention “typical” default values. This refers to the Basic reader and other similar Reader classes.
Some Reader classes, e.g. Latex or AASTex accept aditional keywords, that can customize the output further. See the documentation of these classes for details.
There are two ways to specify the output for the write operation:
For each key (column name) use the given value to convert the column data to a string. If the format value is string-like then it is used as a Python format statement, e.g. ‘%0.2f’ % value. If it is a callable function then that function is called with a single argument containing the column value to be converted. Example:
astropy.io.ascii.write(table, sys.stdout, formats={'XCENTER': '%12.1f',
'YCENTER': lambda x: round(x, 1)},
This can be used to fill missing values in the table or replace values with special meaning. The syntax is the same as used on input. See the Replace bad or missing values section for more information on the syntax. When writing a table, all values are converted to strings, before any value is replaced. Thus, you need to provide the string representation (stripped of whitespace) for each value. Example:
astropy.io.ascii.write(table, sys.stdout, fill_values = [('nan', 'no data'),
('-999.0', 'no data')])


SUDDEN DEATH
Mum-of-three found dead in bed after accidental overdose of painkillers and cocaine as kids slept nearby
by Holly ChristodoulouA TRAGIC mum-of-three died after taking an accidental overdose of painkillers and cocaine as her kids slept nearby, an inquest heard today.
Leanne McElroy's young children aged 13, 12 and nine woke up to find the 30-year-old unresponsive on her bed.
They believed she was sleeping but after she failed to wake up, the alarm was raised and a neighbour climbed through a window and discovered she had passed away.
An inquest heard Leanne had accidentally taken a lethal cocktail of cocaine and painkillers on October 10 last year.
She had been prescribed the strong medication to cope with pain she had been suffering with since the birth of her first child more than 13 years ago.
An operation in 2017 made the pain worse, but "selfless" Leanne still worked as a dinner lady in Manchester to provide for her three sons Dylon, Charlie and Harvey.
Her GP described her as ''on edge'' and ''clinically depressed'' but police found no evidence she had been self harming and put her death down to a tragic accident.
'SHE WAS IN A LOT OF PAIN'
Leanne's heartbroken mum Fiona Hammett told the hearing: ''My daughter was living alone with her three boys at the time of her death. Leanne had health problems and she was in and out of hospital. We do know she was in a lot of pain.
''She had some difficulties after her first pregnancy and needed hospital treatment. She was a private person and liked to deal with things herself but was lovely and bubbly.
''I'm just shaken and saddened there are three children left behind. I'm very sad to see them separated and I have applied for large council accommodation so I can have them more often - but I'm still waiting. Two of them are with their dad and the youngest with his dad."
After the difficult birth, Leanne was prescribed a cocktail of painkillers that she had to take four times a day.
DISCOVERED DEAD IN BED
On October 10, the inquest was told a neighbour climbed into her bedroom using a ladder when her kids said she wouldn't wake up.
Leanne was found under the covers and emergency crews raced to the home found prescription medication addressed to Leanne.
A police statement said: "She appeared to have died whilst in lying in bed. She had been in the house with her children who had been sleeping close by."
The hearing was told there was also no evidence of "illicit drug use" - although a recreational amount of cocaine was found in her system.
Leanne was last seen by a doctor in the summer that year, who tried to arrange scans at North Manchester general hospital to ease her pain.
Her cousin Karen Giles said: "Even though she was going through what she was going through she still got up every day no matter how much pain she was in.
"No one would know, she always had a smile on her face and was always helping other people. She was always there for everyone. I went through something this year she just helped me so much.
''If anything ever needed doing Leanne would be the one who would want to."
Coroner Angarad Davis recorded a verdict of drug related death and said the mum was "inevitably in a lot of pain".

Last time, I discussed some of the challenges of rendering code in a modern-looking webpage, using helpful features like syntax highlighting. The most immediately available solution, a JavaScript library from Google, yielded good-looking code, but it required a server call to Google and some JavaScript execution for a result that we know will be the same every time - and that would therefore be more efficient just to bake into the page HTML, if we can. As implemented, it also required us to put our code snippets in the HTML page itself, making it difficult to develop and test the code.
This, it turns out, is symptomatic of a broader issue: there is a lot of "work" that is generally useful to be able to do automatically on HTML. Formatting code is just one example: it's also really useful to have things like page templating, so that much-reused components like headers and navigation bars don't have to be repeatedly copied and pasted.
This task of programmatically modifying HTML is usually what JavaScript is for. But using JavaScript for these tasks means performing them every single time a user loads your page. If your page is viewed n times, then pre-formatting the HTML beforehand is an O(1) algorithm, where formatting the page using JavaScript is O(n). The n executions just happen on other people's computers.
So, I've just finished reorganizing my website to use Jinja for automatic template compiling, and to perform some other automatic formatting (namely, syntax highlighting) through Python in the process. Jinja is a templating engine that dynamically generates HTML. It is most commonly used from within the web framework Flask, to generate HTML for dynamic websites. But that doesn't mean it can't be used for static websites too! In this case, I just use the Flask app to get a context, in which I can save the results of Flask's render_template() function to a file:
{% highlight python %} with app.app_context(): # Render syntax highlighting template f = open("highlighting.css", 'w') f.write(HtmlFormatter().get_style_defs('.highlight')) f.close() # Render individual pages (but not the base template) for filename in os.listdir('templates'): if '.html' in filename and filename != 'base.html': print("Compiling template {}...".format(filename)) # Link back home (for pages other than index.html) link_home = filename != 'index.html' rendered_html = render_template( filename, link_home=link_home) f = open(filename, 'w') f.write(rendered_html) f.close() {% endhighlight %}Using Python to bake the HTML beforehand also has the side benefit of letting you load text from external files into your HTML - a task which is harder than one might think to do at runtime, basically requiring either PHP or AJAX. Here, we can simply load it using Python and bake it right into the rendered HTML:
{% highlight python %} def code_snippet(snippet_filename, n_start=1, n_end=0): # Open the code snippet and trim it to the desired lines f = open('templates/code_snippets/' + snippet_filename, 'r') lines = f.read().split('\n') n_end = len(lines) if n_end == 0 else n_end text = '\n'.join(lines[n_start-1:n_end]) # Produce the highlight-formatted HTML hl_fmt = HtmlFormatter(linenos="table", linenostart=n_start) highlit_text = highlight(text, get_lexer_for_filename(snippet_filename), hl_fmt) return "With that defined, including external code in the template is as simple as:
``` \{\{ code_snippet('compile.py', 9, 22) | safe \}\} ```
Below is the full script that performs the templating.
All of the page templates
are stored in the library templates
. They all
extend a single template, base.html
. Syntax highlighting is
then performed using the Python library
Pygments.
Writing and hands-on development are done on the templates; then,
a call to python3 compile.py
puts together the "real" HTML
files. I run this script manually, but I envision it could easily be
worked into a CI workflow and done automatically.
Fun fact: as of right now, the templates are still accessible on this
site. This page, for example, is made from two templates:
base.html
(for the
formatting and objects common to all the pages on this site) and
pagerendering.html
(for the content specific to this page.)
But they are unrendered templates - so don't expect anything pretty!
Overall, the result is quite maintainable, while still allowing a huge degree of freedom (you can still just specify a page's HTML completely from scratch with no templating and just pass it through, if you want to), and it performs all of the "busy work" just once - instead of delegating it to JavaScript on the reader's side, on every single page load. This idea isn't necessarily specific to purely static websites either; it could be used to lessen the redundant work done by a web server, or simply to help reduce load times by trimming some JavaScript fat.
I hope this is helpful! I made it in part because I didn't see a solution out there for avoiding some of the busy work of static website composition while still staying close to simple, clean HTML. (That second part disqualified full-fledged CMS's like WordPress and Medium.) But if there is such a solution I missed, please drop me a line - I'd love to know about it, and I'd still be happy to have gotten the experience putting this together.
Edit: After I posted this, a reader named Vitaly Potyarkin reached out to tell me about Pelican, a more full-featured static site generator written in Python. Pelican does everything my solution above does and more: it can take in input in reStructuredText or Markdown in addition to HTML, it can perform syntax highlighting through Pygments, it handles metadata and localization (topics I didn't even touch on here), and its architecture is open enough that you can easily extend its functionality to handle anything it doesn't natively cover. I'd likely recommend it over what I showed above - unless you are extremely interested in rolling a minimal solution yourself.
