REST is buzzword & JSON is ubiquitously present. Are we good at parsing? What about huge JSON array? Can we efficiently enumerate on JSON array? Or use parallel producer-consumer? Can we do it in single line?
<< Previous Article (Lets Shake Hands) |
Next Article (Meet Parallel Producers/Consumers) >> |
In DevFast - Lets Shake Hands, we started with some basic, yet powerful, set of extension methods. Those are powerful in following sense:
In summary, following was bundled together (more on WIKI and Releases):
string
parsing methods (bool
as success indicator with parsed value in out
variable)string
parsing methods (either parsed value is returned or the given default)Exception
when parsing fails)null
values etc)bool
, string
, IEquatable
, IComparable
, ICollection
, Dictionary
etc)async
/ non-async methods for Base64
to/fro conversionsasync
/ non-async methods for other kinds of Crypto transformation.We all know (or getting to know) that technology is changing fast. Everyone talking about RESTful APIs. XML fading and JSON is emerging as a standard format of data exchange over web due to its less verbose light-weight nature and immediate integration with client side scripting. Even in its RAW format, it can be easily understood and manipulated by hand. Moreover, there exist even document oriented databases based on JSON format.
Nonetheless, purpose of this article is neither to explain JSON format nor technologies based on it. Here we are going to talk about how to write succinct & efficient code for JSON operations (serialization/deserialization) and how DevFast can help you do that right!
All the performance statistics are collected on a Windows Machine with following configuration:
Useful links:
As of today, Newtonsoft.JSON (a.k.a. Json.NET) is one of the most performing JSON (De)serialization libraries available. Among many of its useful features, the most commonly used methods are:
Static Methods:
JsonConvert.SerializeObject(dotNetObject)
JsonConvert.DeserializeObject(jsonString)
Instance Methods:
new JsonSerializer().Serialize(writer)
new JsonSerializer().Deserialize(reader)
DevFast takes advantages of these instance methods and proposes following JSON operations as extension methods:
Serialization Methods:
string ToJson<T>(this T source, ...)
void ToJson<T>(this T source, StringBuilder target, ...)
void ToJson<T>(this T source, Stream target, ...)
void ToJson<T>(this T source, TextWriter target, ...)
void ToJson<T>(this T source, JsonWriter target, ...)
Deserialization Methods:
T FromJson<T>(this StringBuilder source, ...)
T FromJson<T>(this string source, ...)
T FromJson<T>(this Stream source, ...)
T FromJson<T>(this TextReader source, ...)
T FromJson<T>(this JsonReader source, ...)
Perhaps, C# Garbage Collection (GC) offers extreme performance but it is also true that NO GC is better than any GC. Talking about Json.NET, the static methods, JsonConvert.SerializeObject
(...
) and JsonConvert.DeserializeObject
(...
), are all good: succinct and up to the mark. Unfortunately, there are times when, having knowledge about our objects, we require more control, like passing own instance of StringBuilder
in order to recover serialized JSON string, reusing those costly StringBuilder
s by avoiding GC cycles, allocation of arrays. Lets consider both methods and identify where DevFast can really help you with its single-liners.
StringBuilder
, we coin, ToJson<T>
(this T
source, StringBuilder
target, ...), extension method.Lets consider some objects of varying sizes to obtain something substantial. Following are sampled statistics (source code):
| ArrayLen | StringLen | Iterations | JsonConvert Time | DevFast Time | Remarks | |
|---|---|---|---|---|---|---|
| SmallObj | - | 58 | 10M | 8545 ms | 8588 ms | DevFast 0.49% slower |
| LargeObj | - | 3976 | 1M | 8413 ms | 7837 ms | DevFast 6.83% faster |
| LargeObj Array | 1K | 4072449 | 1K | 12278 ms | 10348 ms | DevFast 15.71% faster |
Stream
. This stream can be network stream, memory stream, file stream or something else. Again, we need some control on the serialization and thus, falls the burden to write the code. And what can be better than a single-line code. Thus, the need of, ToJson<T>
(this T
source, Stream
target, ...), extension method.Lets consider again, the above three (3) differently sized objects in conjuction with FileStream
this time.
Following are sampled statistics (source code):
| ArrayLen | FileSize | Iterations | JsonConvert Time* | DevFast Time* | Remarks | |
|---|---|---|---|---|---|---|
| SmallObj | - | 58 B | 32K | 4351 ms | 3888 ms | DevFast 10.26% faster |
| LargeObj | - | 3985 B | 32K | 4226 ms | 5023 ms | DevFast 18.84% slower |
| LargeObj Array | 1K | 4081665 B | 128 | 2676 ms | 1794 ms | DevFast 32.96% faster |
*Inclusive of File opening/closing time.
MemoryStream
instead, in order to collect performance statistics, to perform the same round of tests. We obtained following set of sampled statistics (source code):| ArrayLen | FileSize | Iterations | JsonConvert Time | DevFast Time | Remarks | |
|---|---|---|---|---|---|---|
| SmallObj | - | 61 B | 128K | 169 ms | 168 ms | DevFast 0.56% faster |
| LargeObj | - | 3988 B | 128K | 1554 ms | 1342 ms | DevFast 13.64% faster |
| LargeObj Array | 1K | 4081668 B | 256 | 4423 ms | 3073 ms | DevFast 30.51% faster |
StringBuilder.ToString()
, before deserialization can take place; we have obtained, FromJson<T>
(this StringBuilder
source, ...) extension method. If we run our object samples, we obtain following sampled statistics (source code):| ArrayLen | StringLen | Iterations | JsonConvert Time | DevFast Time | Remarks | |
|---|---|---|---|---|---|---|
| SmallObj | - | 58 | 2M | 2772 ms | 3051 ms | DevFast 10.06% slower |
| LargeObj | - | 3976 | 512K | 4853 ms | 4680 ms | DevFast 3.56% faster |
| LargeObj Array | 1K | 4072449 | 512 | 6192 ms | 4828 ms | DevFast 22.02% faster |
Stream
, we introduce FromJson<T>
(this Stream
source, ...) extension method. Lets first again run our object samples using FileStream
, we obtain following sampled statistics (source code):| ArrayLen | StringLen | Iterations | JsonConvert Time* | DevFast Time* | Remarks | |
|---|---|---|---|---|---|---|
| SmallObj | - | 58 | 32K | 1362 ms | 1283 ms | DevFast 5.79% faster |
| LargeObj | - | 3976 | 32K | 1899 ms | 1753 ms | DevFast 7.69% faster |
| LargeObj Array | 1K | 4072449 | 128 | 2417 ms | 1893 ms | DevFast 21.66% faster |
*Inclusive of File opening/closing time.
MemoryStream
, sampled statistics are as follow (source code):| ArrayLen | StringLen | Iterations | JsonConvert Time | DevFast Time | Remarks | |
|---|---|---|---|---|---|---|
| SmallObj | - | 58 | 1M | 1990 ms | 1846 ms | DevFast 7.22% faster |
| LargeObj | - | 3976 | 256K | 3594 ms | 3048 ms | DevFast 15.18% faster |
| LargeObj Array | 1K | 4072449 | 256 | 4214 ms | 2917 ms | DevFast 30.76% faster |
Most of the times. at client side, using JsonConvert
or JsonSerializer
for regular (de)serialization hardly makes any difference, specially with modern hardware; as the user hardly perceives those milliseconds of difference. However, this does NOT hold true, specially at, all time busy, server side. Latency aside, memory too becomes one of the major concerns when we deal with JSON Array, especially BIG ones! There are some commonly observed cases, when we deal with these gigantic arrays:
Even on a modest shared server, this can soon result in OutOfMemoryException
(OOM
), failed/delayed reports etc. In effect, as a quick win, first thought comes to mind is to start creating/receiving smaller size files for processing. At least, this buys some time as OOM
are avoided, though, the file count has increased and perhaps some other part of the code became complicated and so as bookkeeping. But hold on! what if we can read those JSON array element one by one? Perform computation in-sync or in-async? What if we can decide how many of those objects should stay in memory at given point in time?
To address these (or similar) requirements, DevFast proposes two (2) approaches to deal with the situation at hands:
IEumerable<T>
BlockingCollection<T>
to support Parallel Producer-Consumer (PPC)As a first approach, following extension methods are proposed:
Serialization Methods:
string ToJsonArray<T>(this IEnumerable<T> source, ...)
void ToJsonArray<T>(this IEnumerable<T> source, StringBuilder target, ...)
void ToJsonArray<T>(this IEnumerable<T> source, Stream target, ...)
void ToJsonArray<T>(this IEnumerable<T> source, TextWriter target, ...)
void ToJsonArray<T>(this IEnumerable<T> source, JsonWriter target, ...)
Deserialization Methods:
IEnumerable<T> FromJsonAsEnumerable<T>(this StringBuilder source, ...)
IEnumerable<T> FromJsonAsEnumerable<T>(this string source, ...)
IEnumerable<T> FromJsonAsEnumerable<T>(this Stream source, ...)
IEnumerable<T> FromJsonAsEnumerable<T>(this TextReader source, ...)
IEnumerable<T> FromJsonAsEnumerable<T>(this JsonReader source, ...)
Lets quickly see what we gain in terms of memory and/or speed:
| Operation | Peak Memory (JsonConvert Vs DevFast) |
JsonConvert Time | DevFast Time | Remarks | Link |
|---|---|---|---|---|---|
| Serialization*M1 | 2,599,284 K Vs 22,968 K | 7218 ms | 6177 ms | DevFast 14.4% faster | Source Code |
| Deserialization*M2 | 3,092,008 K Vs 23,884 K | 13392 ms | 27331 ms | DevFast 104.08% slower | Source Code |
As a matter of fact, IEnumerable approach would keep one object alive per iteration (i.e. elements would be (de)serialized as iterator moves and hopefully GC
ed on each iteration), thus those noticeable memory gain. Nonetheless, sometimes it might be beneficial to let the (de)serialization in parallel as (producer)consumer. Thus, following set of extension methods is proposed:
Serialization Methods:
string ToJsonArrayParallely<T>(this BlockingCollection<T> source, ...)
void ToJsonArrayParallely<T>(this BlockingCollection<T> source, StringBuilder target, ...)
void ToJsonArrayParallely<T>(this BlockingCollection<T> source, Stream target, ...)
void ToJsonArrayParallely<T>(this BlockingCollection<T> source, TextWriter target, ...)
void ToJsonArrayParallely<T>(this BlockingCollection<T> source, JsonWriter target, ...)
Deserialization Methods:
void FromJsonArrayParallely<T>(this StringBuilder source, BlockingCollection<T> target, ...)
void FromJsonArrayParallely<T>(this string source, BlockingCollection<T> target, ...)
void FromJsonArrayParallely<T>(this Stream source, BlockingCollection<T> target, ...)
void FromJsonArrayParallely<T>(this TextReader source, BlockingCollection<T> target, ...)
void FromJsonArrayParallely<T>(this JsonReader source, BlockingCollection<T> target, ...)
Another feature of such an approach is that we can control the number of objects we would like to keep in transit, during the whole operation, by assigning BoundedCapacity
to our BlockingCollection
(in other words, controlling memory profile). Lets quickly tabulate sample of memory and speed statistics:
| Operation | Bounded Capacity* | Peak Memory (JsonConvert Vs DevFast) |
DevFast Time | Link |
|---|---|---|---|---|
| Serialization | NONE | 95,736 K | 7105 ms | Source Code |
| 256 | 25,476 K | 8403 ms | ||
| Deserialization | NONE | 26,932 K | 30469 ms | Source Code |
| 256 | 25,020 K | 31134 ms |
*Must be instrumented with sample data, especially when producer is faster than consumer.
As listed above, lets see how we can handle the two (2) cases, JSON file processing & Reporting, using PPC
with DevFast.
In order to demostrate the idea, we have (source code):
<film>
(normally it contains 1000 rows with 13 columns)SELECT * FROM sakila.film where film_id <=
SOME_UPPER_LIMIT and film_id >
SOME_LOWER_LIMIT{(0, 100), (100, 200), (200, 300) ... (900, 1000)}
BlockingCollection
BlockingCollection
)While running sample code we obtain following sampled performance statistics:
In order to demostrate the idea, we have (source code):
While running sample code we obtain following sampled performance statistics:
Though, the above sample shows a simple PPC
pattern of single producer (i.e. deserializer) single consumer (i.e. our dequeuing while
loop). Nonetheless, following patterns can also be easily constructed:
C# .Net comes with Deflate
& GZip
compression out of the box. DevFast takes the advantage over the fact and proposes following extension methods:
Compression Methods:
Task CompressAsync(this ArraySegment<byte> source, Stream target, ...)
Task CompressAsync(this byte[] source, Stream target, ...)
Task CompressAsync(this Stream source, Stream target, ...)
Task CompressAsync(this StringBuilder source, Stream target, ...)
Task CompressAsync(this string source, Stream target, ...)
Decompression Methods:
Task<string> DecompressAsStringAsync(this Stream source, ...)
Task DecompressAsync(this Stream source, StringBuilder target, ...)
Task DecompressAsync(this Stream source, Stream target, ...)
Task<byte[]> DecompressAsync(this Stream source, ...)
Task<ArraySegment<byte>> DecompressAsSegmentAsync(this Stream source, ...)
Reason behind introducing these extensions on ArraySegment<byte>
& StringBuilder
is to avoid the extra Array (byte or string) creation/copy operations. As these methods are quite straight forward, we quickly lok at these; so that we can look at something more interesting in the next section. Following snapshot provide a quick look on the usage of these methods:
It is true, compression extension methods usage is not rocket science and technically less interesting (yet useful, and who does not love these single liners... haha!). But, moving forward lets think bigger (and better)... afterall, we have introduced all these extensions. We are in a position, now, to exploit the possibility of low-latency pipeline, yet pursue readability with the help of these single-liners. To see it, we must set a non-trivial use case. Lets begin:
Client Story:One fine day, your client asks you to implement a feature with following user-story:
As a user, I would like to have an extract of all the transactions of a given date.
Product Owner Story:Based on user story, product owner, after an apocalyptical introspection/brain-storm, decides to create a new service "TransactionReporting" and claims the budget for the same. Client/PO negotiate on a delivery within 6 months with 100K $ of budget + some regular running feature maintenance budget.
Architect Story:Once budget is sanctioned, PO initiates bilateral talk, with an Architect in confidence, to arrange a solution design, Tech Specs etc. As, WebAPI/
JSON
are buzzwords, Architect proposes usingJSON
data exchange in streaming overGET
. He also noticed that the byte volume could be high for available bandwidth, thus, suggests compression. Furthermore, due to large number of records, he warns about some significant latency during the database fetch operation (select query
), thus, suggest implementation ofPOST
(with202
response) to acceptDate
. And anotherGET
(for status monitoring purpose,200
and201
responses) and a finalGET
(to actually recover the file,200
response) with GZip compressed JSON file in streaming.(other possibilities: WebHooks, 3rd party Middleware, FTP, shared resource for file exchange etc... Nevermind...)
Team Lead Story:Once design is on the table, Team Lead starts continuous delivery cycle with developers in the team and start creating technical tasks with associated functional & technical specs and sprint planning. So he decides a common multi-layered approach with Presentation/Business/Data Access/Data etc layers.
Developer Story:Based on received functional/tenchnical specs, developer's work reduced to:
- Development of all the tiers
- Unit & Integration Testing
- Performance Testing
Now having all these stories available, we have a better view of the problem. From a developer perspective (from AGILE point of view), we have lot to do under these three (3) major category. Testing (even under TDD), code coverage, improving SONAR KPIs etc demands a lot of efforts and time. And to be truthful, Performance testing (latency, volume, network load etc tests) is procrastinated most of the time until the very end. And if those tests are unsatisfactory... hmmm! God helps the team :)
Anyway, in this given situation, we know that we need to perform performance testing at least at following places:
GET
) : Beyond the scope of this article and warrants a separate article; nonetheless, have a look at PushStreamContent and just to begin with create a bogus large text/json file to be transferred from server to client using Get
with a Stopwatch.So this section is all about point 3) & 4) and here we will see how DevFast is going to help you out. I urge you to pause reading and think for a while, if it would be you, what would be your solution look like? Also, assume for the moment you do NOT have DevFast package available to you!
In order to understand what we are trying to achieve, it is important we perform the iteration in the same fashion as a developer, who iteratively improves his solution everytime his performance KPIs are in RED, would do! So lets look at following approaches:
We consider following kind-of-pseudocode: (// as comments lines)
//This line is a Memory Black Hole!
//Fetching a small set of record is all OK in this fashion
//but fetching 10's of thousands or millions of records! No way!

//And in such a case, wts the use of performance testing?
List<TransactionRecord> transactionRecords = dataAccessInstance
.FetchTransactionRecordFor(dateOfTheTransaction);
//Another devil in the corner! Likely to trigger OOM
//or breach Max Object size
var jsonString = JsonConvert.SerializeObject(transactionRecords);
//just need to choose where the file is: on FAR network system,
//or locally?
File.WriteAllText(@"<Full Path Of JSON file>", jsonString);
//After doing all writing, again reading from 1 file and writing to another!!!
//I/O operations are known to be slower! Thus, latency is expected.
//Careful choice of buffersize/compression scheme might be helpful
FileInfo compressedFile = compressionEngine.Compress(@"<Full Path Of JSON file>");
So we have problems with List
s, but thanks to yield return we can iterate over our implementation. We consider following kind-of-pseudocode: (// as comments lines)
//once we have DataReader: //while(dataReader.Read()) //{ // yield return CreateNewTransactionRecord(dataReader); // usual column to property mapping //} using(var fileHandle = CreateFileWriter(@"<Full Path Of JSON file>")) { //writing "[" fileHandle.Write(jsonArrayStartToken); foreach(var obj in dataAccessInstance.FetchTransactionRecordAsEnumerable(dateOfTheTransaction)) { //writing json string of the object fileHandle.Write(JsonConvert.SerializeObject(obj)); //writing "," fileHandle.Write(objectSeparatorToken); } //writing "]" fileHandle.Write(jsonArrayEndToken); } //After doing all writing, again reading from 1 file and writing to another!!! //I/O operations are known to be slower! Thus, latency is expected. //Careful choice of buffersize/compression scheme might be helpful FileInfo compressedFile = compressionEngine.Compress(@"<Full Path Of JSON file>");
All looks good for the moment, nonetheless, we notice that while we fetch data from DB we neither do JSON serialization nor do file writing and vice-versa. Furthermore, we also know that both DB operation and File operation are I/O bound, so we must consider Parallel Producer-Consumer (PPC) implementation. Very interstingly, once we are on PPC, we are free to launch many queries in parallel on disjoint partitions of the data.
In order to decouple data fetching from JSON writing lets consider following kind-of-pseudocode: (// as comments lines)
//Inside PopulateTransactionRecordParallel function: //try //{ // while(dataReader.Read()) // { // //Adding objs using usual column to property mapping // blockingCollection.Add(CreateNewTransactionRecord(dataReader)); // } //} //finally //{ // blockingCollection.CompleteAdding();// mandatory, else consumer will go in infinite sleep (DEADLOCK!) //} using(var fileHandle = CreateFileWriter(@"<Full Path Of JSON file>")) { var collection = new BlockingCollection();//perhaps with some capacity var dbtask = Task.Run(() => dataAccessInstance .PopulateTransactionRecordParallel(dateOfTheTransaction, collection)); //writing "[" fileHandle.Write(jsonArrayStartToken); foreach(var obj in collection.GetConsumingEnumerable()) { //writing json string of the object fileHandle.Write(JsonConvert.SerializeObject(obj)); //writing "," fileHandle.Write(objectSeparatorToken); } //writing "]" fileHandle.Write(jsonArrayEndToken); //in case, task throw some error. await dbtask.ConfigureAwait(false); } //After doing all writing, again reading from 1 file and writing to another!!! //I/O operations are known to be slower! Thus, latency is expected. //Careful choice of buffersize/compression scheme might be helpful FileInfo compressedFile = compressionEngine.Compress(@"<Full Path Of JSON file>");
All looks good for the moment, nonetheless, we notice that there are other places where we can improve performance, for example:
This is where DevFast will pitch-in to help you (of course, with its single liners!!!). But before, we begin we need to, again, assume few things:
Lets see how using DevFast library we can re-write Approach 2 and Approach 3 and generate some sample statistics:
| Operation | Approach 2 Time |
Approach 4 (DevFast) Time |
Peak Memory Bytes |
Remarks | Link | |
|---|---|---|---|---|---|---|
| (Total Records = 1M, Uncompressed JSON File = 337,569,004 Bytes, GZip Compression) | ||||||
| Serialization | 33930 ms | 24865 ms | 42,172 K | DevFast is 26.71% faster |
Source Code | |
| Deserialization2 | - | 13491 ms3 | 24,932 K3 | - |
1Must be instrumented with sample data, especially when producer is faster than consumer.
2For Approach 2, no mechanism is known to fetch data as IEnumerable without Memory pressure! For DevFast only Compression & Looping considered (DB operations left for readers)
3Fast consumer effect (counting loop is faster than deserialization). This time can be viewed as pure Enumerable Pipeline Horsepower (Deserialization+Decompression time)
| Operation | Bounded Capacity1 | Approach 3 Time |
Approach 5 (DevFast) Time |
Peak Memory Bytes (3 & 5) |
Remarks | Link |
|---|---|---|---|---|---|---|
| (Total Records = 1M, Uncompressed JSON File = 337,569,004 Bytes, GZip Compression) | ||||||
| Serialization | NONE | 31839 ms | 16599 ms | 647,816 K | DevFast is 47.86% faster |
Source Code |
| 256 | 41496 ms | 31614 ms | 45,388 K | DevFast is 23.81% faster |
||
| Deserialization2 | NONE | - | 14334 ms3 | 26,736 K3 | - | |
| 256 | - | 14634 ms3 | 26,744 K3 | - |
1Must be instrumented with sample data, especially when producer is faster than consumer.
2For Approach 3, no mechanism is known to fetch data in BlockingCollection directly! For DevFast only Compression & Looping considered (DB operations left for readers)
3Fast consumer effect (counting loop is faster than deserialization). This time can be viewed as pure PPC Pipeline Horsepower (Deserialization+Decompression time)
Here we wrote about what we have proposed until v1.1.2 and we have a lot more to propose and constraint by the time :( Nonetheless, we hope that this article has a lots of statistics, snapshots, and 1-liners for you.
Incessantly, we are adding more and more code in this lib, in order to bring you helpful one-liners. We would be happy to know your requirements and on the way, we'll prioritize those. Hope to see you back in a couple of months.

White fish served in a classic sauce vierge made from olive oil, lemon juice, chopped tomatoes and herbs. Simple and sophisticated.
For the sauce vierge, pour the olive oil in a non-reactive pan. Whisk in the lemon juice until well-combined. Add the chopped tomatoes, shallot and garlic.
Heat the pan over a medium heat until the sauce vierge mixture is just warmed through. Add the tarragon and season, to taste, with salt and freshly ground black pepper. Set aside.
For the coley, season the coley fillet with salt and freshly ground black pepper.
Heat the oil in a non-reactive frying pan over a medium heat. Add the seasoned coley fillets, skin-side down, and fry for 1-2 minutes until golden-brown.
Turn the fillets over using a fish slice and cook for a further 1-2 minutes, or until just cooked through.
Drizzle the lemon juice over the fish fillets and remove from the heat.
To serve, arrange the coley fillets into the centre of a serving plate. Drizzle over the tarragon sauce vierge (whisk the tarragon sauce vierge again before serving until well combined). Spoon the green salad alongside.

What is Adaptive User Interface?
An adaptive user interface (also known as AUI) is a user interface (UI) which adapts, that is changes, its layout and elements to the needs of the user or context and is similarly alterable by each user. These mutually reciprocal qualities of both adapting and being adaptable are, in a true AUI, also innate to elements that comprise the interface's components; portions of the interface might adapt to and affect other portions of the interface. This later mechanism is usually employed to integrate two logically distinct components, such as an interactive document and an application (e.g. a web browser) into one seamless whole. The user adaptation is often a negotiated process, as an adaptive user interface's designers ignore where user interface components ought to go while affording a means by which both the designers and the user can determine their placement, often (though not always) in a semi-automated, if not fully automated manner. An AUI is primarily created based on the features of the system, and the knowledge levels of the users that will utilize it.
What Adaptive User Interface could do?
Adaptive User Interface could be the future of User Interface, knowing each user’s need we can adapt to their requirements and display information accordingly.
Consider a UI that could not just learn but adapt according to the user.
Types
• Adaptive presentation
The goal behind adaptive presentation is to display certain information based on the current user. This may mean that users with only basic knowledge of a system will only be shown minimal information.
Conversely, a user with advanced knowledge will have access to more detailed information and capabilities.
A way that the AUI can achieve this differentiation could be to hide information to be presented based on the user's experience level. Another possibility is to control the amount of links to relevant sources on the page.
• Adaptive navigation
Adaptive navigation intends to guide a user to their specific goal within the system by altering the way the system is navigated based on certain factors of the user. These factors can include the users expertise level with the system/subject, the current goal within the system, and other relevant factors.
Examples of adaptive navigation can be achieved in many ways, similar to adaptive presentation. These can include examples such as providing links to help achieve a user's specific goal, giving reference on a page to where a user is, or altering the resources available to the user.

--- layout: post title: When duplication is not duplication post_id: 61 categories: - essays and rants date: 2008-03-06 15:56:00.000000000 -07:00 author: Jamis permalink: 2008/3/6/when-duplication-is-not-duplication.html ---
I was looking through some C code today, and stumbled across this lovely little gem:
1 2 3 4 5 |
tmp = "\"#"; while (*tmp) { FD_SET(*tmp, url_encode_map); tmp++; } |
Now, be honest. I don’t care how good you are at C, it takes you a few brain cycles to process that and figure out that it is just setting two bits in a bit field. It really should have been written like this:
1 2 |
FD_SET('"', url_encode_map); FD_SET('#', url_encode_map); |
This raises the question: why wasn’t it? I’ll tell you why:
Programmers have this burning desire to avoid code duplication. We’re taught, almost since the cradle, to abhor duplicated code and to avoid it all cost. Duplicating code is evil, it leads to unmaintainable code, and propogates bugs. Never, ever, do it!!!
Allow me to let you in on a little secret.
Calling the same function twice is NOT duplicating code. Not if the arguments change between calls.
Even calling the same function three times in a row is kosher. Four times, even. At some point, you might want to consider a loop, if the arguments can be determined functionally, but only do so when the list of similar function calls is harder to read and understand than the loop is. This is often when the loop takes fewer lines of code than the function calls do:
1 2 3 4 |
for (i = 127; i < 256; i++) { FD_SET(i, hdr_encode_map); FD_SET(i, url_encode_map); } |
There. Had to get that off my chest. Now, back to work.

We have been working on something called "Programming with Professors". We have been asking faculty if they could give us they had problems in research/teaching which could be solved via programming. We would then compile a list of problem statements which interested chapter members can pick from and solve, improving their programming skill.Example: a student who knows R/Python could write scripts that aid in data analysis/implement an algorithm/simulate a phenomena, whose output would be useful to the professor in his/her work."

I had some code lying around which I thought I’d share with you. It is an adaption of a Processing algorithm by ART+COM, visualizing an elegant growing plant.
The source code has been organized in two simple classes so it might help you when learning from the tutorial on classes. The first class, Tendril, defines a single branch in the plant. As it grows it calculates the position of new segments by steering its current heading a bit to the left or right, hence the spiraling shape. The second class, Plant, defines a group of tendrils. It has some simple methods to grow and draw all the tendrils together.
size(600, 600) from math import pi, sin, cos, radians class Tendril: def __init__(self, x, y, width=15): """ A new sinewy tendril at location x and y. Its segment width will gradually become smaller as it grows. """ self.x = x self.y = y self.width = width self.angle = random(2*pi) - pi # random angle in radians. self.segments = [] self.v = 0 def grow(self, distance=3.0, curl=1.0, step=0.02): """ Tendril segment growth using fluid, spiral sine functions, taken from the ART+COM Tendrils class for Processing. """ # Think of a tendril having a steering compass. # For each new segment, the compass shifts a bit left or right. self.x += cos(self.angle) * distance self.y += sin(self.angle) * distance self.v += random(-step, step) self.v *= 0.9 + curl*0.1 self.angle += self.v self.segments.append( (self.x, self.y, self.angle) ) def draw(self, path=None): """ Draws all the segments in the tendril, as separate ovals or as a single path if one is supplied. """ n = len(self.segments) for i, (x, y, angle) in enumerate(self.segments): r = (1-float(i)/n) * self.width # size gradually decreases. if path != None: path.oval(x, y, r, r) else: oval(x, y, r, r) class Plant: def __init__(self, x, y, tendrils=30, width=15): """ A collection of tendrils. """ self.x = x self.y = y self.tendrils = [] for i in range(tendrils): self.tendrils.append( Tendril(self.x, self.y, width) ) def grow(self, distance=3.0, curl=1.0, step=0.02): """ Grow a new segment on each of the plant's tendrils. """ for b in self.tendrils: b.grow(distance, curl, step) def draw(self): """ Draw the plant. """ for tendril in self.tendrils: tendril.draw() def path(self): """ Return the plant as a path consisting of ovals. """ path = BezierPath() for tendril in self.tendrils: tendril.draw(path) return path background(0.12, 0.12, 0.06) nofill() stroke(1, 0.5) strokewidth(0.5) plant = Plant(WIDTH/2, HEIGHT/2, tendrils=20) for i in range(200): plant.grow(curl=1.0, step=0.02) plant.draw()
With a simple adaption we can use the plant.path() method as input for Core Image. This way we can transform the plant shape as a layer of pixel data. Simply add the lines of code below the image to the bottom of the script, and play around with the curl parameter a bit.
coreimage = ximport("coreimage") canvas = coreimage.canvas(WIDTH, HEIGHT) layer = canvas.append( plant.path(), fill=color(1,0), stroke=color(1,0.8), strokewidth=0.2 ) layer.filter("zoomblur", amount=10) canvas.draw()

Based on the ‘Tendrils’ algorithm by ART+COM


Activity: Arrays
Let's start with an array of some films, books, or tv shows that you like:
var films = ["Starship Troopers", "Total Recall", "Robocop", "Basic Instinct"]
var books = ["East of Eden", "White Noise", "100 Years of Solitude"]
And then let's use the .push()
method to add more names!
//Let's add some values to our array using `.push()`
console.log("I have " + films.length + " favorite films")
//Push some more and see the length change!
Challenges!
- Log the first element of your array
- Log the second element of your array
- Log the last element of your array. Hint: how can you find out how long your array is? It should always print out the last element even if you add or remove elements from the array
- Log the second to last element of your array
- Log the middle element of the array (rounded down if there are an even number of elements)

Endpoints and EDS¶
LbEndpoint¶
An Endpoint that Envoy can route traffic to.
{
"endpoint": "{...}",
"metadata": "{...}",
"load_balancing_weight": "{...}"
}
- endpoint
- (Endpoint) Upstream host identifier
- metadata
- (Metadata) The endpoint metadata specifies values that may be used by the load balancer to select endpoints in a cluster for a given request. The filter name should be specified as envoy.lb. An example boolean key-value pair is canary, providing the optional canary status of the upstream host. This may be matched against in a route’s ForwardAction metadata_match field to subset the endpoints considered in cluster load balancing.
- load_balancing_weight
(UInt32Value) The optional load balancing weight of the upstream host, in the range 1 - 128. Envoy uses the load balancing weight in some of the built in load balancers. The load balancing weight for an endpoint is divided by the sum of the weights of all endpoints in the endpoint’s locality to produce a percentage of traffic for the endpoint. This percentage is then further weighted by the endpoint’s locality’s load balancing weight from LocalityLbEndpoints. If unspecified, each host is presumed to have equal weight in a locality.
Attention
The limit of 128 is somewhat arbitrary, but is applied due to performance concerns with the current implementation and can be removed when this issue is fixed.
LocalityLbEndpoints¶
A group of endpoints belonging to a Locality. One can have multiple LocalityLbEndpoints for a locality, but this is generally only done if the different groups need to have different load balancing weights or different priorities.
{
"locality": "{...}",
"lb_endpoints": [],
"load_balancing_weight": "{...}",
"priority": "..."
}
- locality
- (Locality) Identifies location of where the upstream hosts run.
- lb_endpoints
- (LbEndpoint) The group of endpoints belonging to the locality specified.
- load_balancing_weight
(UInt32Value) Optional: Per priority/region/zone/sub_zone weight - range 1-128. The load balancing weight for a locality is divided by the sum of the weights of all localities at the same priority level to produce the effective percentage of traffic for the locality.
Weights must be specified for either all localities in a given priority level or none.
If unspecified, each locality is presumed to have equal weight in a cluster.
Attention
The limit of 128 is somewhat arbitrary, but is applied due to performance concerns with the current implementation and can be removed when this issue is fixed.
- priority
(uint32) Optional: the priority for this LocalityLbEndpoints. If unspecified this will default to the highest priority (0).
Under usual circumstances, Envoy will only select endpoints for the highest priority (0). In the event all endpoints for a particular priority are unavailable/unhealthy, Envoy will fail over to selecting endpoints for the next highest priority group.
Priorities should range from 0 (highest) to N (lowest) without skipping.
ClusterLoadAssignment¶
Each route from RDS will map to a single cluster or traffic split across clusters using weights expressed in the RDS WeightedCluster.
With EDS, each cluster is treated independently from a LB perspective, with LB taking place between the Localities within a cluster and at a finer granularity between the hosts within a locality. For a given cluster, the effective weight of a host is its load_balancing_weight multiplied by the load_balancing_weight of its Locality.
{
"cluster_name": "...",
"endpoints": [],
"policy": "{...}"
}
- cluster_name
- (string, REQUIRED) Name of the cluster. This will be the service_name value if specified in the cluster EdsClusterConfig.
- endpoints
- (LocalityLbEndpoints) List of endpoints to load balance to.
- policy
- (ClusterLoadAssignment.Policy) Load balancing policy settings.
ClusterLoadAssignment.Policy¶
[ClusterLoadAssignment.Policy proto]
Load balancing policy settings.
{
"drop_overload": "..."
}
- drop_overload
(double) Percentage of traffic (0-100) that should be dropped. This action allows protection of upstream hosts should they unable to recover from an outage or should they be unable to autoscale and hence overall incoming traffic volume need to be trimmed to protect them.
Note
v2 API difference: This is known as maintenance mode in v1.

Mane insists Liverpool's front three can keep going
Cape Town - Sadio Mane is adamant Liverpool's front three are not feeling any physical fatigue, saying "the tiredness is in the head".
Mane, Mohamed Salah and Roberto Firmino start virtually every match for Jurgen Klopp's side but that, plus their international commitments, means the numbers they are racking up are significant.
Senegal international Mane has played 131 matches for club and country since the start of the 2017-18 season, Egypt's Mohamed Salah has 133 while Brazilian Roberto Firmino has a remarkable 149 appearances.
Mane certainly does not seem to be showing any signs of fatigue affecting his form with the 27-year-old having scored 12 times in 19 games.

"Honestly, I think it is all in the head. The tiredness is in the head, so as long as the body recovers well, I think it is not difficult for us to play every single game if the team needs us and the coach needs us.
"I think we will be able to play and help the team. When they need me, I will be ready for the team to give everything.

Liverpool are going to need that indefatigably over the next couple of months as they are currently two matches into a 14-game stretch in 43 days up to and including their entry into the FA Cup in the first week of January.
That also includes two matches in 24 hours on different continents because of their involvement in the Carabao Cup and Club World Cup.
Should they progress through the League Cup quarter-final tie at Aston Villa in December they would then face a two-legged semi-final, meaning potentially a further seven matches in a month.
Mane will be in the squad which travels to Qatar for the Club World Cup as Liverpool seek to claim a trophy they have never won before.
"I always say to win games and win trophies, motivates players all the time," added Mane.
"If we can win the Club World Cup then it will give us more momentum.
"Hopefully we are going to win it and give us another blast of high energy to go again for the rest of the season."

The Circle star Woody shared some cute selfies of him and his mother for her 49th birthday and apologised for missing her special day.
The 18-year-old posted: ‘Wishing a wonderful Birthday to the best Mum I’ve ever had!! Sorry couldn’t be there today but I love you lots!!!!!! xx #legend’
Zoe responded to his sweet message with an eager: ‘LOVE YOU WOO BEAR’ along with a bear emoji.
The Radio 2 presenter shares Woody with musician Norman Cook (or better known as Fatboy Slim) and celebrated her birthday at the Lime Wood Hotel in New Forest, being showered with gifts and cake.
She uploaded a snap of the gifts she received, and it’s safe to say she had a ball.
Zoe was presented with endless balloons, a homemade cake, cards, a walrus plush, flowers and make up.

Sharing the gifts on Instagram, she wrote: ‘Thank you for the birthday love peeps. Being spoilt rotten #limewoodhotel #newforest #hideaway #escapetothecountry #countrymonkeys #cakeface’ along with a cake emoji and present emoji.
Meanwhile, Zoe has recently split from her boyfriend Michael Reed after nearly two years together, according to reports.
It marked the first public relationship the It Takes Two presenter had since the tragic suicide of her boyfriend Billy Yates in 2017.
According to sources, Zoe called time on the romance with construction boss Michael amid claims she was ‘growing uncomfortable’ with reports he was using her fame for his own benefit.
‘Zoe knew deep down the relationship wasn’t going anywhere,’ a friend told The Sun. ‘She enjoyed her time with Michael but came to the conclusion he wasn’t a keeper, despite him believing they were getting serious.
‘There were certain things she grew uncomfortable with, such as him wanting to become a model and act. Her close circle feared he was using her to enhance his own career.’

My name is Tam and welcome to my portfolio page!
Below are a list of projects that have been completed:
I became curious in programming after noticing my kids at work using their smartphones to send messages. During my childhood we would send messages by writing them on paper, folding them up, and then secretly passing them in class without getting caught. Nevertheless, I thought it was interesting to see a new generation of kids sending messages through a programming medium. It's really awesome that programming has changed our ways of communicating, and I want to be a part of that, but sometimes I do miss the classy way of writing messages on paper.

- Timing issue which caused Selenium to hang under certain circumstances.
- Selenium now resolves attributes even if they are given as a Symbol
# Version 0.3.7
Release date: 2010-04-09
This is a drop in compatible maintainance release. It’s mostly important for driver authors.
### Added
- RackTest scans for data-method which rails3 uses to change the request method
### Fixed
- Don’t hang when starting server on Windoze
### Changed
- The driver and session specs are now located inside lib! Driver authors can simply require them.
# Version 0.3.6
Release date: 2010-03-22
This is a maintainance release with minor bug fixes, should be drop in compatible.
### Added
- It’s now possible to load in external drivers
### Fixed
- has_content? ignores whitespace
- Trigger events when choosing radios and checking checkboxes under Selenium
- Make Capybara.app totally optional when running without server
- Changed fallback host so it matches the one set up by Rails’ integration tests
# Version 0.3.5
Release date: 2010-02-26
This is a mostly backwards compatible release, it does break the API in some minor places, which should hopefully not affect too many users, please read the release notes carefully!
### Breaking
- Relative searching in a node (e.g. find(‘//p’).all(‘//a’)) will now follow XPath standard this means that if you want to find descendant nodes only, you’ll need to prefix a dot!
- `visit` now accepts fully qualified URLs for drivers that support it.
- Capybara will always try to run a rack server, unless you set Capybara.run_sever = false
### Changed
- thin is preferred over mongrel and webrick, since it is Ruby 1.9 compatible
- click_button and click will find , clicking them does nothing in RackTest
### Added
- Much improved error messages in a multitude of places
- More semantic page querying with has_link?, has_button?, etc...
- Option to ignore hidden elements when querying and interacting with the page
- Support for multiple selects
### Fixed
- find_by_id is no longer broken
- clicking links where the image’s alt attribute contains the text is now possible
- within_fieldset and within_table work when the default selector is CSS
- boolean attributes work the same across drivers (return true/false)

in its header, or (2) perform its IO in a
try{}
block and then catch
IOExceptions.
Here is the example program modified to catch exceptions:
import java.io.*; class WriteTextFile2 { public static void main ( String[] args ) { String fileName = "reaper.txt" ; try { // append characters to the file FileWriter writer = new FileWriter( fileName, true ); writer.write( "Alone she cuts and binds the grain,\n" ); writer.write( "And sings a melancholy strain;\n" ); writer.write( "O listen! for the Vale profound\n" ); writer.write( "Is overflowing with the sound.\n\n" ); writer.close(); } catch ( IOException iox ) { System.out.println("Problem writing " + fileName ); } } }
The constructor, the write()
method, and the close()
method
can throw an IOException.
All are caught by the catch
block.
This program opens the file "reaper.txt" for appending. Run it and see what it does.

BMI is a measurement of a person's leanness or corpulence based on their height and weight, and is intended to quantify tissue mass. It is widely used as a general indicator of whether a person has a healthy body weight for their height. Specifically, the value obtained from the calculation of BMI is used to categorize whether a person is underweight, normal weight, overweight, or obese depending on what range the value falls between. These ranges of BMI vary based on factors such as region and age, and are sometimes further divided into subcategories such as severely underweight or very severely obese. Being overweight or underweight can have significant health effects, so while BMI is an imperfect measure of healthy body weight, it is a useful indicator of whether any additional testing or action is required. Refer to the table below to see the different categories based on BMI that is used by the calculator
You should not use BMI as a measure if you're pregnant. Get advice from your midwife or GP if you're concerned about your weight.

Logitech Purchases Blue Microphones to Better Serve Gamers, Podcasters, and More – MacStories
I record every episode of @theclassnerd on a Blue Snowball plugged into my iPad, and have been thrilled with the quality. Blue having more resources behind them is exciting.
Is anyone else good at listening to their own podcasts? Listening back to @theclassnerd is just a reminder of all the weird ways I phrase things.
And I ordered a bag…
If kids get new backpacks at the beginning of the school year, maybe I need another Tom Bihn bag. 🤔
Today was another day in foster parenting I wish I could share more of, but can’t. It was the perfect picture of how the world isn’t black and white. It’s beautiful and messy at the same time.
Thanks @manton for sharing the latest episode of @internetfriends. It gave me a lot to think about in terms of how I approach the web. Well done @ablaze and @drewcoffman. Instant subscribe.

New Alzheimer’s Drug Shows Big Promise in Early Trial Results - The New York Times
As someone whose family has been dramatically impacted by Alzheimer’s on all sides, this is excellent news.
I should add that if you’re on the Shortcuts beta, it does work there too. Once we can share Shortcuts links and Drafts is officially updated to work with Shortcuts (currently in beta), I’ll share the updated Drafts actions and shortcuts.
I realized my workflow to upload photos to Micro.blog didn’t work with all image file types. I’ve updated it to always convert images to JEPG which should solve the problem.
Top golf with friends is what summer is all about.
I’ve updated my Tools of Choice page on my website. It’s amazing how much has changed since February. Most of that is how big an effect Drafts 5 has had on my workflows.
Just arrived at a coffee shop, and there are more iPads in use than Macs. We’re slowly taking over!
I tried Keep It several months back, and couldn’t really get into it. Now Viticci is using it, I try it, and suddenly I don’t know how I lived without it. How does that guy do it?
📚 I’ve been waiting for Thrawn Alliances all summer. Marc Thompson’s narration was so good on the first Thrawn book, I didn’t even consider buying a text version. Should be a good listen as I set up my classroom.

Ogun makes final list of partnership programme - The Nation Newspaper
Adekunle Jimoh, Ilorin
Ogun State has been selected among the successful participants in the coming National Forest Carbon Partnership Facility and United Nations’ Reducing Emission from Deforestation and Forest Degradation projects (FCPF/REDD+).
The Director of Survey, Demarcation, Inventory and Extension, Ministry of Forestry, Mr. Adewale Shonubi, who spoke at Oke-Mosan, Abeokuta, said the programme, aimed at encouraging developing countries to reduce emission from deforestation and degradation by enhancing, sustaining, as well as conserving forest carbon stock, began with an assessment in the 36 states.
He said 17 states were selected for reassessment, with seven pre-qualifying for the scoping mission assessment, where Ogun finally qualified among the last three selected states.
Shonubi noted that the political will and support of the Governor Dapo Abiodun administration to the programme contributed to the prequalification and final selection of the state in the keenly scrutinised scoping mission assessment.

The Director, Non–Timber Department, Dr. Gbotemi Adeleye, said government’s commitment to forest management and development strategy has raised the level of consciousness for forest communities’ participation in resources protection and sustenance towards achieving an all-round forest development system across the state.
He said the climate change mitigation programme of the UN REDD+, as a Clean Development Mechanism, would not only reduce emission from deforestation and degradation, but also generate incentive funds to qualified states in their enhancement of forest carbon stock, through the FCPF/REDD+’s Readiness Carbon Fund.
The director said the state would benefit financially for its effort at reducing emission from deforestation, thereby boosting forestry development projects and programmes, as the government remained committed to Public, Private Partnership investments to improve the state’s economy.
