Since version 0.3, Julia has come with a command-line interface — a REPL — that is completely written in Julia (PR #6270). Among other features, the REPL provides code completion, history with reverse search, and a rich set of customizable key bindings. (See the Interacting with Julia part of the manual for the REPL documentation.) Even so, the REPL in Julia 0.6 includes quite a few new visual tweaks and features. In this blog post, we look into some of these changes and customizations to the Julia REPL, available in 0.6.
It is quite common (as in the Julia manual and in subsequent code blocks of this blog post) to write snippets of Julia code like they were copied straight from a REPL session, for example:
julia> f() = rand(10^6)
f (generic function with 1 method)
julia> @time f();
0.052948 seconds (25.05 k allocations: 8.769 MiB)
If you wanted to try out this code in 0.5, you would typically copy the code into a text editor, remove the julia>
prompt, remove the output, and then finally have code that looked like:
f() = rand(10^6);
@time f();
which could then be pasted back into the REPL to be executed.
In 0.6, the REPL comes with a feature called prompt pasting by which a pasted expression starting with julia>
automatically has prompts and eventual output scrubbed before being executed.
If you have a 0.6 REPL currently at hand, you can try to copy and paste the example with the prompt and output above directly into the REPL and you will see that it works in exactly the same way as if we had manually removed them.
Unfortunately, for technical reasons (no support for bracket pasting), this feature does not work in the standard cmd-terminal on Windows. There are, however, multiple alternative terminal emulators on Windows that do support this, e.g. Console2 or Cygwin.
When an error occurs, the REPL prints the exception that was thrown along with a stack trace: a list tracing back through the sequence of function calls and source code lines that were being executed when the error occurred. In previous versions of Julia, the stack trace might omit some function calls that were inlined, making it harder to understand. In Julia 0.6, the stack trace includes function calls that were inlined. Unfortunately, in combination with the Julia idiom of breaking complex tasks into many smaller functions, this can sometimes lead to long stack traces. Furthermore, the stack trace includes the type signature of the methods being called, but these type signatures can sometimes be quite verbose (e.g. for union types or types taking many parameters). Julia 0.6 greatly improves the readability of this output by coloration, numbering, and interactive features described below.
In earlier Julia versions, stack traces were printed without much structure. Everything was printed in bold red which made it a bit difficult to find the information one was looking for. As an example, here is a screenshot from an error thrown on 0.5:
Finding the relevant information can be quite difficult, especially the file name and line numbers since they are not aligned in any way. In 0.6, this is what is currently shown for the same error:
Stack trace presentation has improved significantly: Stack traces no longer print in red, while associated error messages continue to print in red.
Stack traces also no longer print entirely in bold; only function names and line information now appear in bold.
These changes visually separate the most frequently sought information (the associated error message, function names and line information) from the surrounding text, making that information much easier to pick out.
Additionally, each stack frame in the stack trace prints numbered, making individual stack frames easier to refer to.
(Apart from these changes to stack trace presentation, BoundsErrors
no longer display with the associated collection’s contents, decreasing visual noise.)
Furthermore, you can now customize stack frame function and line information print colors by setting the environment variables JULIA_STACKFRAME_FUNCTION_COLOR
and JULIA_STACKFRAME_LINEINFO_COLOR
respectively.
For example, setting
julia> ENV["JULIA_STACKFRAME_LINEINFO_COLOR"] = :cyan;
julia> ENV["JULIA_STACKFRAME_FUNCTION_COLOR"] = :yellow;
and rerunning the example above yields
In addition to the visual changes to the stack trace, there is also a new interactive feature, possible now that we can refer to stack frames by number.
After a stack trace has been printed, you can simply enter the number of one of the stack frames in the REPL, press CTRL + Q
and the file will be opened in
an editor at the line number corresponding to that stack frame.
To set the editor, use the environment variable EDITOR
, for example ENV["EDITOR"] = "subl"
for the Sublime Text editor.
This can be used when you quickly want to fix a typo or just to jump around with the editor in the call stack leading up to the error.
Note that it is currently not possible to open the location of a stack frame that refers to code directly evaluated in the REPL.
While not strictly related to the REPL, it is still within the scope of this post to describe some of the changes made to the color printing functionalities in Julia 0.6.
Previously, it was only possible to use 8 colors for printing (see help?> Base.text_colors
) by using the function print_with_color
.
In 0.6, light versions of these colors (prefixed by light_
) are also supported, increasing the number of named colors to 16.
In addition, an integer between 0 and 255 can now be used as a color (see this chart for a reference).
These new colors are possible to use wherever an option previously existed to change the color of some element in the REPL.
Another change is that, by default, the function print_with_color
no longer prints in bold; instead a new keyword argument bold::Bool
was introduced that controls this.
Some examples of this functionality are given in the figure below:
Previously, the default style of entered code and shown objects in the REPL was bold; this was changed in 0.6 to instead use standard “light” text. However, as the example below shows, it is possible to change this back to bold, or to any other color:
If you would like to take REPL customization even further, I would encourage you to take a look at the OhMyREPL
package (author of this post is also author of that package).
Some of the features described in this post were upstreamed to Base Julia from that package, but for now, some of the more advanced features, like syntax highlighting, matching bracket highlighting and customization of input/output prompts, still live only in the OhMyREPL
package.

I've been working with a system lately that has no database abstraction (besides Z SQL methods, which is close enough to no abstraction to qualify). The worst problem I see with it is the tight coupling between various pieces of code as they pass around result sets, or method signatures created from result sets. Let's say we're dealing with a shopping cart application, and the particular example of adding an item to the cart. You'd probably expect an interface like addItem(itemID). But perhaps addItem wants to recalculate the total, so it has to fetch information about the item. Just as likely, the code that called addItem may have had to fetch information about the item because it was finding related items, or validating that this item is available, or any number of things. We have redundancy - they are both fetching information about an item, but failing to pass that information through.
So, maybe the signature should be addItem(item) where item is a result set. Then we fetch the information early on, and keep passing it around. Except, what is item? Is it the results of SELECT * FROM item WHERE id = X? That would be simple. But everything probably isn't stored in the item table, so there's probably a join or two in there. Hopefully all pieces of the program can agree on exactly which joins are appropriate.
But what if the item came from another source than our standard SELECT? Maybe we are getting all the items from a category. Do we want to do all the joins necessary to get all the information about the item? Probably not - maybe all we want is a is a brief description of the item, and we don't want to pull in five different tables we won't use.
Then maybe you stop passing result sets around, and make it explicit, e.g. displayItem(itemTitle, itemDescription, itemImageHeight,...). Okay, nevermind that. The explicit signatures make it clear what sort of information each function needs, but that's just way too painful. Plus even given such a signature, you may be tempted to find just the right SELECT statement that gets you the needed values but no more. Your SQL fragments explode.
This is when things start to not fit together very well. Perhaps you want to reuse your category search in the administration screen, but you need just one more join, so you add it. Or maybe you now want to be able to iterate through that search result and do things like addItem on each row. But your result sets don't quite match up. Resolution? Well, you can just pass what you have, and maybe addItem won't need them after all, and if it does it will refetch the row. Maybe you can find the rows you want, then refetch them before passing them to addItem. It gets worse over the web, where you have to go back to passing IDs around. You don't have to pass IDs around, but then you are just asking for a world of pain (think addItem?itemTitle=Tickle+Me+Elmo &itemID;=40&parentCategory;=Toys &parentCategoryID;=30&...).
Maybe the answer is to let the database do the work (ala ACS). Instead of an addItem function at all, just do the SQL right there. Is it really that much harder to do INSERT INTO cart_items (cart_id, item_id) VALUES (20, 15)? Maybe write or use a nice little SQL wrapper to make it a bit easier (SQLDict, for instance). Your database schema is your API.  This might work okay (though there is considerable debate on the matter), but it only works for a while. Eventually you are going to want to deal with something not in the database - a web service, data in the filesystem, whatever, and you'll have conflicting APIs. Not to mention the other maintenance difficulties and tight coupling to your database.
After going down that path (if only hypothetically), maybe it seems best to sacrifice a little of the speed for a bit more sanity. You make all your interfaces ID-based, back to addItem(itemID). But at that point you are doing a large number of unnecessary queries.
So after working without an ORM, I remain firmly convinced that's the wrong way to work with a database. Without an ORM you can have good performance, or you can have simple method and function signatures, but I doubt you can get both without writing your own ad hoc ORM. Without an ORM mostly you will get bad performance and hard to read code.
True, an ORM typically can't deal with every query you might write in SQL (LEFT JOIN being the most common query that typically does not have an ORM equivalent), so your custom-written queries will - when viewed in isolation - run faster, but in a system the ORM will both be easier to use, and faster. Because the ORM deals with specific sets of information (a single row from a single table, typically) it can more easily cache database results. The data is easier to deal with because there's only as many kinds of data as there are tables in the database (more or less), where with ad hoc queries you have as many kinds of data as there are queries.
That said, ad hoc ORMs are neither uncommon (even if the authors don't realize what they've created) nor are they necessarily bad. A little tedious to write, perhaps, but an ORM isn't magic.
(Whether you should use an RDBMS at all is another question. Perhaps another day? In you are interested in an ORM for Python you might want to look at the Python Wiki page on the subject, or SQLObject, by me. But it's free, so this essay isn't meant to sell SQLObject to you, I swear.)
your object is clearly not (or in a real RDBMS application, shouldn't be) simply a single row. why not have objects defined at the scripting level and cache there? perhaps your object crosses five tables. fine. the first time you need it, read it (all of it, in one maybe monstrous join), cache it for five minutes, and use it in any function that needs it. no more database calls necessary. if you write to the object (any of those five tables), mark the data as dirty or remove it from memory.
keep the databse clean and simple. write an object oriented layer in your scripting language of choice. then use that abstraction in the per-page scripts you write. your pages will be much simpler and your web app will be much more powerful for it.

The `RecyclerView` adapter's `onNotifyDataSetChanged` method does not
specify what about the data set has changed, forcing any observers to
assume that all existing items and structure may no longer be valid.
`LayoutManager`s will be forced to fully rebind and relayout all visible
views.

(##) Suppressing
You can suppress false positives using one of the following mechanisms:
* Using a suppression annotation like this on the enclosing
element:
```kt
// Kotlin
@Suppress("NotifyDataSetChanged")
fun method() {
notifyDataSetChanged(...)
}
```
or
```java
// Java
@SuppressWarnings("NotifyDataSetChanged")
void method() {
notifyDataSetChanged(...);
}
```
* Using a suppression comment like this on the line above:
```kt
//noinspection NotifyDataSetChanged
problematicStatement()
```
* Using a special `lint.xml` file in the source tree which turns off
the check in that folder and any sub folder. A simple file might look
like this:
```xml
<?xml version="1.0" encoding="UTF-8"?>
<lint>
<issue id="NotifyDataSetChanged" severity="ignore" />
</lint>
```
Instead of `ignore` you can also change the severity here, for
example from `error` to `warning`. You can find additional
documentation on how to filter issues by path, regular expression and
so on
[here](https://googlesamples.github.io/android-custom-lint-rules/usage/lintxml.md.html).
* In Gradle projects, using the DSL syntax to configure lint. For
example, you can use something like
```gradle
lintOptions {
disable 'NotifyDataSetChanged'
}
```
In Android projects this should be nested inside an `android { }`
block.
* For manual invocations of `lint`, using the `--ignore` flag:
```
$ lint --ignore NotifyDataSetChanged ...`
```
* Last, but not least, using baselines, as discussed
[here](https://googlesamples.github.io/android-custom-lint-rules/usage/baselines.md.html).

Sergio Aguero to start alongside Lionel Messi against Uruguay
Sergio Aguero will start alongside Lionel Messi as Argentina face Uruguay in a friendly in Tel Aviv on Monday.
The Manchester City striker will return to the Albiceleste side as manager Lionel Scaloni gets his final look at his team before the start of World Cup qualifying next year.
Aguero, who sat out Friday's victory over Brazil in Saudi Arabia, and Barcelona playmaker Messi are the only players Scaloni has confirmed will definitely play.
They could play in a front three with Inter Milan's Lautaro Martinez or Paulo Dybala of Juventus but Scaloni will wait before making the rest of his selection.
Speaking at a press conference reported by TyC Sports, Scaloni said: "Let's wait a little longer. Some players are tired after the game against Brazil, which is normal for the game we had, but nobody has problems.
"We will take half a day more because I would like to take a fresh team."
Scaloni does not want to stray too far from his preferred side but recognises the game is a good opportunity to experiment.
He said: "Beyond that is not ideal to try but as we consider it is the last before the qualifiers we can dare to try some players in an important game."
The game is likely to see Messi come up against his Barcelona team-mate Luis Suarez.
Scaloni said: "We are going to play against a side that is one of the best in the world.
"They have a mix of youth and experience at the top level, and we know how dangerous they are."

A deque (pronounced "deck") is very similar to a vector. It manages its elements with a dynamic array, provides random access, and has almost the same interface as a vector. The difference is that with a deque the dynamic array is open at both ends. Thus, a deque is fast for insertions and deletions at both the end and the beginning (Figure 6.2).
To provide this ability, the deque is implemented typically as a bunch of individual blocks, with the first block growing in one direction and the last block growing in the opposite direction (Figure 6.3).
To use a deque, you must include the header file <deque>[9] :
[9] In the original STL, the header file for deques was <deque.h>.
#include <deque>
There, the type is defined as a template class inside namespace std:
namespace std { template <class T, class Allocator = allocator<T> > class deque; }
As with vectors, the type of the elements is passed as a first template parameter and may be of any type that is assignable and copyable. The optional second template argument is the memory model, with allocator as the default (see Chapter 15).[10]
[10] In systems without support for default template parameters, the second argument is typically missing.
Deques have the following differences compared with the abilities of vectors:
Inserting and removing elements is fast both at the beginning and at the end (for vectors it is only fast at the end). These operations are done in amortized constant time.
The internal structure has one more indirection to access the elements, so element access and iterator movement of deques are usually a bit slower.
Iterators must be smart pointers of a special type rather than ordinary pointers because they must jump between different blocks.
In systems that have size limitations for blocks of memory (for example, some PC systems), a deque might contain more elements because it uses more than one block of memory. Thus, max_size() might be larger for deques.
Deques provide no support to control the capacity and the moment of reallocation. In particular, any insertion or deletion of elements other than at the beginning or end invalidates all pointers, references, and iterators that refer to elements of the deque. However, reallocation may perform better than for vectors, because according to their typical internal structure, deques don't have to copy all elements on reallocation.
Blocks of memory might get freed when they are no longer used, so the memory size of a deque might shrink (however, whether and how this happens is implementation specific).
The following features of vectors also apply to deques:
Inserting and deleting elements in the middle is relatively slow because all elements up to either of both ends may be moved to make room or to fill a gap.
Iterators are random access iterators.
In summary, you should prefer a deque if the following is true:
You insert and remove elements at both ends (this is the classic case for a queue).
You don't refer to elements of the container.
It is important that the container frees memory when it is no longer used (however, the standard does not guarantee that this happens).
The interface of vectors and deques is almost the same, so trying both is very easy when no special feature of a vector or a deque is necessary.
Table 6.9 through Table 6.11 list all operations provided for deques.
| Operation | Effect |
| deque<Elem> c | Creates an empty deque without any elements |
| deque<Elem> c1(c2) | Creates a copy of another deque of the same type (all elements are copied) |
| deque<Elem> c(n) | Creates a deque with n elements that are created by the default constructor |
| deque<Elem> c(n,elem) | Creates a deque initialized with n copies of element elem |
| deque<Elem> c(beg,end) | Creates a deque initialized with the elements of the range [beg,end) |
| c.~deque<Elem>() | Destroys all elements and frees the memory |
| Operation | Effect |
| c.size() | Returns the actual number of elements |
| c.empty () | Returns whether the container is empty (equivalent to size()==0, but might be faster) |
| c.max_size() | Returns the maximum number of elements possible |
| c1 == c2 | Returns whether c1 is equal to c2 |
| c1 != c2 | Returns whether c1 is not equal to c2 (equivalent to ! (c1==c2)) |
| c1 < c2 | Returns whether c1 is less than c2 |
| c1 > c2 | Returns whether c1 is greater than c2 (equivalent to c2<c1) |
| c1 <= c2 | Returns whether c1 is less than or equal to c2 (equivalent to ! (c2<c1) ) |
| c1 >= c2 | Returns whether c1 is greater than or equal to c2 (equivalent to ! (c1<c2) ) |
| c.at(idx) | Returns the element with index idx (throws range error exception if idx is out of range) |
| c[idx] | Returns the element with index idx (no range checking) |
| c.front() | Returns the first element (no check whether a first element exists) |
| c.back() | Returns the last element (no check whether a last element exists) |
| c.begin() | Returns a random access iterator for the first element |
| c.end() | Returns a random access iterator for the position after the last element |
| c.rbegin() | Returns a reverse iterator for the first element of a reverse iteration |
| c.rend() | Returns a reverse iterator for the position after the last element of a reverse iteration |
| Operation | Effect |
| c1 = c2 | Assigns all elements of c2 to c1 |
| c.assign (n,elem) | Assigns n copies of element elem |
| c.assign (beg,end) | Assigns the elements of the range [beg,end) |
| c1.swap(c2) | Swaps the data of c1 and c2 |
| swap(c1,c2) | Same (as global function) |
| c.insert (pos,elem) | Inserts at iterator position pos a copy of elem and returns the position of the new element |
| c. insert (pos,n,elem) | Inserts at iterator position pos n copies of elem (returns nothing) |
| c.insert (pos,beg,end) | Inserts at iterator position pos a copy of all elements of the range [beg,end) (returns nothing) |
| c.push_back (elem) | Appends a copy of elem at the end |
| c.pop_back() | Removes the last element (does not return it) |
| c.push_front (elem) | Inserts a copy of elem at the beginning |
| c.pop_front() | Removes the first element (does not return it) |
| c.erase(pos) | Removes the element at iterator position pos and returns the position of the next element |
| c.erase (beg,end) | Removes all elements of the range [beg,end) and returns the position of the next element |
| c. resize (num) | Changes the number of elements to num (if size () grows, new elements are created by their default constructor) |
| c.resize (num, elem) | Changes the number of elements to num (if size () grows, new elements are copies of elem) |
| c.clear() | Removes all elements (makes the container empty) |
Deque operations differ from vector operations only as follows:
Deques do not provide the functions for capacity (capacity () and reserve ()).
Deques do provide direct functions to insert and to delete the first element (push_front () and pop_front()).
Because the other operations are the same, they are not reexplained here. See Section 6.2.2, for a description of them.
Note that you still must consider the following:
No member functions for element access (except at ()) check whether an index or an iterator isvalid.
An insertion or deletion of elements might cause a reallocation. Thus, any insertion or deletioninvalidates all pointers, references, and iterators that refer to other elements of the deque. Theexception is when elements are inserted at the front or the back. In this case, references andpointers to elements stay valid (but iterators don't).
In principle, deques provide the same support for exception handing as do vectors (see page 155). The additional operations push_front() and pop_front() behave according to push_back() and pop_back () respectively. Thus, the C++ standard library provides the following behavior:
If an element gets inserted with push_back () or push_front () and an exception occurs, these functions have no effect.
Neither pop_back () nor pop_front () throw any exceptions.
See Section 5.11.2, for a general discussion of exceptions handling in the STL and Section 6.10.10, for a list of all container operations that give special guarantees in face of exceptions.
The following program is a simple example that shows the abilities of deques:
// cont/deque1. cpp #include <iostream> #include <deque> #include <string> #include <algorithm> using namespace std; int main() { //create empty deque of strings deque<string> coll; //insert several elements coll.assign (3, string("string")); coll.push_back ("last string"); coll.push_front ("first string"); //print elements separated by newlines copy (coll.begin(), coll.end(), ostream_iterator<string>(cout,"\n")); cout << endl; //remove first and last element coll.pop_front(); coll.pop_back(); //insert ''another'' into every element but the first for (int i=1; i<coll.size(); ++i) { coll[i] = "another " + coll [i]; } //change size to four elements coll.resize (4, "resized string"); //print elements separated by newlines copy (coll.begin(), coll.end(), ostream_iterator<string>(cout,"\n")); }
The program has the following output:
first string string string string last string string another string another string resized string

Selectors are used to fetch page elements inside jquery Array
They Use CSS-Like Syntax as follow
$("tag")
: Select all of the <tag> elements$(".className")
: Select all elements that have the className class applied$("#identifier")
: Select the element with the id of identifier$("tag.className")
: Select all <tag> elements that have the className class appliedTo select elements based on their position in the document tree, use the Hierarchy Selectors.
The Hierarchy Selectors work by examining the position of target elements relative to other elements:
$("parent > child")
: selects "child" elements that are immediate descendants of the "parent"$("ancestor descendant")
: selects "descendant" elements as long as they have an "ancestor" element somewhere above them$("prev + next")
: selects the "next" element if it is immediately preceded by a "prev" element$("prev ~ siblings")
: selects all "siblings" elements that come after a "prev" element| Cell 1 | Cell 2 |

Honor V30 Will Also be Available in a PRO Version - Gizchina.com
by PierreHonor V30 Will Also be Available in a PRO Version
5 (100%) 2 votes
Honor’s strategy and brand development manager, Zhang Xiaoyun, just revealed a very interesting detail over on Chinese social Weibo. Zhang did indeed confirm there’ll be a Honor V30 Pro as well. Thus the basic Honor V30 won’t be the only device we’ll see hitting the market next week.
Honor V30 Will Also be Available in a PRO Version
The “revelation” wasn’t actually planned, or so we’d like to believe. The Honor V30 Pro name does indeed appear in the “device it was sent from area”; which basically means Zhang Xiaoyun sent the Weibo message from the upcoming device.
This isn’t even the first time the Honor V30 series surfaces online in such way. Some time back, Honor’s Vice President had the same “problem” which at the time confirmed the existence of a V30 series.
Either way, since the company has already announced an official launch event in Beijing on November 26th, this isn’t a real scoop. We just learned that Honor’s first 5G flagship phone will be coming with a Pro variant as well. Alternatively, the Pro model could be the only one featuring the next generation network standard.
As far as specs are concerned, the Honor V30 is expected to pack flagship-grade hardware. This means we’ll probably find the Huawie Kirin 990 CPU along with its support for NSA and SA dual-mode 5G.
The V30 series by Honor could also feature the much talked about “Matrix Camera” technology. According to previous rumors this tech should create a new mobile photography experience such as long-distance and close-range dual recording, with the help of multiple lenses and AI artificial intelligence algorithms.
Design wise, the V30 will most likely adopt a pill-shaped punch-hole screen with two cameras, very slim bezels and a high screen to body ratio.

Hi! I'm @nshntarora,
and I've recently started to brush up my concepts.
This project is an attempt to implement a Virtual DOM to understand how it works.
Here's how it will work,
-
Click on "Start" button below
You'll notice some elements are rendered
-
Now, open your DevTools and go to the elements inspector.
-
Locate the elements that were just created.
-
Keep DevTools open and click on reload.
You will see an element is updated.
Your elements inspector will highlight only the element that has changed.
If you missed the highlight, reload the page and click on "Reload".
This time, keep your eyes on the elements inspector.

I recently moved back to Oregon from sunny San Diego. I grew up in Southern Oregon but lived in Portland for three years before moving to Southern California. I love the outdoors - hiking, skiing, paddleboarding, anything that gets me outside!
Another passion of mine is travel, more specifically travel in Central and South America. I majored in Spanish in college and have used my language skills abroad in Honduras, Guatemala, Ecuador and Spain. I hope to take some time after Epicodus to live - and perhaps code - from a Spanish speaking country.


public final class ServiceAccountantManager
extends java.lang.Object
ServiceAccountantManager
manages all instances of ServiceAccountant
by reference to the javax.xml.rpc.Service
hashcode.
This class is intended to be used by the HTTP transport layer of the Axis
engine; i.e. DfpHttpSender.invoke(MessageContext)
calls
recordMessage(MessageContext)
.
The default behavior of the manager is to create service accountants
automatically when the first response is received for that service and to not
retain a reference to that service. A service which accounting is enabled for
is called a "registered" service. A service which has its reference managed
by this manager is called a "retained" service. If you would like to retain
references to all created services (so this class can be used a service
manager), then setRetainServices(boolean)
should be called with
true
. This can also be set by setting the jvm property: com.google.api.ads.dfp.lib.serviceaccountantmanager.retainservice=true
For memory management, the clear()
method can be used to remove all
references to services so that they may be garbage collected. Again, this is
only needed if service retention is enabled (not by default).
| Modifier and Type | Method and Description |
|---|---|
void |
clear()
Clears all references of managed services.
