Java Mission Control from JDK 1.8.0_161 frozen upon startup on Mac OS X : <p>I'm trying to launch Java Mission Control as provided in the JDK 1.8.0_161 on Mac OS X High Sierra (10.13.2, with Supplemental Update of January 2018) and the JMC application is frozen, i.e. I'm unable to browse in the JVM Browser panel.</p>
<p>As I've other former JDK installed, therefore I've checked JMC with the following versions with success:</p>
<ul>
<li>1.8.0_121</li>
<li>1.8.0_144</li>
<li>1.8.0_151</li>
</ul>
<p>So the problem is very specific to the JDK 1.8.0_161.</p>
<p>(To see your JDKs, run the command <code>/usr/libexec/java_home -V</code>)</p>
<p>(To run a former JMC, i.e. <code>/Library/Java/JavaVirtualMachines/jdk1.8.0_151.jdk/Contents/Home/bin/jmc</code>)</p>
<p>As a side verification, I've run the JMC of the JDK 1.8.0_161 on Windows 10 with success.</p>
<p>So do you experience the same issue ?</p>
<p>Is there some settings to tweak to have it working ?
(E.g. would it be an issue related to Mac OS X Gatekeeper !?)</p>
<p>And how to report it to Oracle properly ... I've searched their bug database without success, and when I try to submit a bug, I cannot figure which would be the right subcategory (c.f. <a href="https://bugreport.java.com/submit_intro.do" rel="noreferrer">https://bugreport.java.com/submit_intro.do</a>), as JMC is not listed in the TOOLS section ... Any advice !?</p>

Python: Create automated strictly-designed multi-page .pdf report from .html : <p>What are good Python-based options to create strictly designed .pdf reports from .html?</p>
<p>I've attached a draft .pdf to illustrate the following points:</p>
<ul>
<li>The design of the report is rather strictly designed. In other words "Looks matter".</li>
<li>The report contains complex vector graphics (package: <a href="http://matplotlib.org/" rel="noreferrer">Matplotlib</a>).These may slightly differ in size .</li>
<li>The report contains images.</li>
<li>The report contains a large number of numbers / strings filled in dynamically.</li>
<li>Optimally, the solution would use open source packages.</li>
<li>We create our .html with <a href="https://www.djangoproject.com/" rel="noreferrer">Django</a>.</li>
<li>The report may span multiple pages.</li>
</ul>
<p>It looks as if there was already a good amount of very diverse packages facilitating reporting. Just to name a few, there are <a href="https://github.com/xhtml2pdf/xhtml2pdf" rel="noreferrer">xhtml2pdf</a>, <a href="http://weasyprint.org/" rel="noreferrer">weasyprint</a>, <a href="https://djangopackages.org/packages/p/django-wkhtmltopdf/" rel="noreferrer">django-wkhtmltopdf</a>.</p>
<p>In my experience, it’s easy with these tools to create a .pdf from your content. The hard part comes when the .pdf needs to fall into a highly-defined design structure as in our case. Unfortunately, I was not able to find example .pdfs for the different pdf generation packages that have a highly designed structure.</p>
<p>What is your experience with this? Which options worked well for you? Are there well done complex examples that I’ve overlooked?</p>
<p><a href="https://i.stack.imgur.com/GM8cl.png" rel="noreferrer"><img src="https://i.stack.imgur.com/GM8cl.png" alt="Some example of a strictly-designed "Looks matter" report"></a></p>

using statment with array require Dispose : The following code using the "using" statement was meant to avoid some sort of memory leak which renders the code slow over long files:

string[] lines = File.ReadAllLines(Files.cuboHistorico, Encoding.Default);
bool header = true;

cubo.UF = Select.Uf(reg[5]);
cubo.Cidade = reg[6];
cubo.Regiao = reg[7];
cubo.Codigo = reg[8];
cubo.Produto = reg[9];
...
cubo.VlCom = Select.ParseFloat(reg[63]);
cubo.Cnpj = reg[64];
cubo.CodProdOriginal = reg[65];
cubos.Add(cubo);
db.SaveChanges();
}
}
}
But the line with the "using" statement give the error: "'string[]': type used in a using statement must be implicitly convertible to 'System.IDisposable'"
As "Split" is regular part of dot.net I have no clue whatsoever how to implement of the IDisposable interface in such a case.

Detecting incorrect assertion methods : <p>During one of the recent code reviews, I've stumbled upon the problem that was not immediately easy to spot - there was <code>assertTrue()</code> used instead of <code>assertEqual()</code> that basically resulted into a test that was <em>testing nothing</em>. Here is a simplified example:</p>
<pre><code>from unittest import TestCase
class MyTestCase(TestCase):
def test_two_things_equal(self):
self.assertTrue("a", "b")
</code></pre>
<p>The problem here is that the test would pass; and technically, the code is valid, since <a href="https://docs.python.org/3/library/unittest.html#unittest.TestCase.assertTrue" rel="noreferrer"><code>assertTrue</code> has this optional <code>msg</code> argument</a> (that gets the <code>"b"</code> value in this case).</p>
<p>Can we do better than rely on the person reviewing the code to spot this kind of problems? Is there a way to <em>auto-detect</em> it using static code analysis with <code>flake8</code> or <code>pylint</code>?</p>

How can I strip the data:image part from a base64 string of any image type in Javascript : <p>I am currently doing the following to decode base64 images in Javascript:</p>
<pre><code> var strImage = "";
strImage = strToReplace.replace("data:image/jpeg;base64,", "");
strImage = strToReplace.replace("data:image/png;base64,", "");
strImage = strToReplace.replace("data:image/gif;base64,", "");
strImage = strToReplace.replace("data:image/bmp;base64,", "");
</code></pre>
<p>As you can see above we are accepting the four most standard image types (jpeg, png, gif, bmp);</p>
<p>However, some of these images are very large and scanning through each one 4-5 times with replace seems a dreadful waste and terribly inefficient.</p>
<p>Is there a way I could reliably strip the data:image part of a base64 image string in a single pass? </p>
<p>Perhaps by detecting the first comma in the string?</p>
<p>Thanks in advance.</p>

Check is a variable is not empty : Could someone please let me know how I check is a variable is empty?
I have a variable called `new_date`. I am reading dates into this variable but sometimes there is no date read in (the date does not exist). I want to check if the variable new_date is empty and do something different if there is not date in the variable
e.g.
I have the code below which first checks if variable `picked` is less than variable `prev_final` and `new_date` is a date.
if (picked < prev_final) & isinstance(new_date, pd.datetime)
# add the value from NEW_DATE
list_final.append(new_date)
# and update the prev_final for the next iteration of the loop
prev_final = new_date
else: # same idea if conditions not met
list_final.append(picked)
prev_final = picked
to this first line I would like to add a condition that `new_date` also must have a date (not empty). If its empty I'd like the code to use the else i.e. if new_date is empty I would like the code to drop down to where I append `picked` to the `list_final` and `prev_final` and not append `new_date`)
e.g.
if (picked < prev_final) & isinstance(new_date, pd.datetime) & (new_date isnot empty)
But I just need to know how to check if new_date is empty.
Any help would be much appreciated.

C code keeps running forever : I am trying to find the largest prime factor of a huge number in C ,for small numbers like 100 or even 10000 it works fine but fails (By fail i mean it keeps **running and running** for tens of minutes on my core2duo and i5) for very big `target` numbers (See code for the target number.)
Is my algorithm correct?
I am new to C and really struggling with big numbers. What i want is correction or guidance not a solution i can do this using python with bignum bindings and stuff (*I have not tried yet but am pretty sure*) but not in C. Or i might have done some tiny mistake that i am too tired to realize , anyways here is the code i wrote:
#include <stdio.h>
// To find largest prime factor of target
int is_prime(unsigned long long int num);
long int main(void) {
unsigned long long int target = 600851475143;
unsigned long long int current_factor = 1;
register unsigned long long int i = 2;
while (i < target) {
if ( (target % i) == 0 && is_prime(i) && (i > current_factor) ) { //verify i as a prime factor and greater than last factor
current_factor = i;
}
i++;
}
printf("The greates is: %llu \n",current_factor);
return(0);
}
int is_prime (unsigned long long int num) { //if num is prime 1 else 0
unsigned long long int z = 2;
while (num > z && z !=num) {
if ((num % z) == 0) {return 0;}

Viewing current Spring (Boot) properties : <p>I run a Spring Boot application as a .jar file which partly takes its properties from application.yml residing inside the jar while the other part of properties is being provided from another application.yml residing outside the jar. Some of the properties from the outside overwrite the properties from the inside. In order to test whether the properties were overwritten properly I would like to see the currently active ones. Is that achieveable at all out of the box? Or is the only solution to extend my application by property output logic?</p>

Modify @OneToMany entity in Spring Data Rest without its repository : <p>In my project I use object of type <em>A</em> which has OneToMany relation (orphanRemoval = true, cascade = CascadeType.ALL, fetch = FetchType.EAGER) to objects of type <em>B</em>. I need SpringDataRest (SDR) to store complete full <em>A</em> object with its <em>B</em> objects (children) using single one POST request. I tried several combinations in SDR, the only one which worked for me, was to create @RepositoryRestResource for object <em>A</em> and to create @RepositoryRestResource also for object <em>B</em>, but mark this (<em>B</em>) as exported=false (if I did not create repository out of object <em>B</em> at all, it would not work -> just <em>A</em> object would be stored on single POST request, but not its children (@OneToMany relation) of type <em>B</em>; the same outcome occurs if exported=false is omitted for <em>B</em> repository).
Is this ok and the only way how to achieve it (single POST request with storing all objects at once)?</p>
<p>The reason I'm asking, in my previous example, I have to (I would like to) control all objects "lifecycle" by using <em>A</em>'s repository. I am ok with it, because <em>A</em>-><em>B</em> relation is composition (<em>B</em> does not exists outside of <em>A</em>). But I have serious problem of editing (also removing) one certain object of type <em>B</em> by SDR using its parent repository (since object <em>B</em> doest not have its own repository exported). Maybe, this is not possible by definition. I have tried these solutions:</p>
<ul>
<li>PATCH for "/A/1/B/2" does not work -> method not allowed (in headers
is "Allow: GET, DELETE") -> so, also PUT is out of question</li>
<li>Json Patch would not work either - PATCH for "/A/1" using json patch
content-type [{"op": "add", "path": "/B/2", ....}] -> "no such index
in target array" - because Json Patch uses scalar "2" after "array"
as a index to its array. This is not practical in Java world, when
relations are kept in Set of objects - indexing has no meaning
at all.</li>
<li>I could export repository (exported=true) of object <em>B</em> for
manipulating it "directly", but this way I would loose ability to
store the whole object <em>A</em> with its <em>B</em> objects at one single POST
request as I have mentioned before.</li>
</ul>
<p>I would like to avoid sending the whole <em>A</em> object with one single tiny modification of its <em>B</em> object for PUT, if possible.
Thank you.</p>

React w/hooks: prevent re-rendering component with a function as prop : <p>Let's say I have:</p>
<pre><code>const AddItemButton = React.memo(({ onClick }) => {
// Goal is to make sure this gets printed only once
console.error('Button Rendered!');
return <button onClick={onClick}>Add Item</button>;
});
const App = () => {
const [items, setItems] = useState([]);
const addItem = () => {
setItems(items.concat(Math.random()));
}
return (
<div>
<AddItemButton onClick={addItem} />
<ul>
{items.map(item => <li key={item}>{item}</li>)}
</ul>
</div>
);
};
</code></pre>
<p>Any time I add an item, the <code><AddItemButton /></code> gets re-rendered because addItem is a new instance. I tried memoizing addItem:</p>
<pre><code> const addItemMemoized = React.memo(() => addItem, [setItems])
</code></pre>
<p>But this is reusing the setItems from the first render, while </p>
<pre><code> const addItemMemoized = React.memo(() => addItem, [items])
</code></pre>
<p>Doesn't memoize since <code>items</code> reference changes.</p>
<p>I can'd do</p>
<pre><code> const addItem = () => {
items.push(Math.random());
setItems(items);
}
</code></pre>
<p>Since that doesn't change the reference of <code>items</code> and nothing gets updated.</p>
<p>One weird way to do it is:</p>
<pre><code> const [, frobState] = useState();
const addItemMemoized = useMemo(() => () => {
items.push(Math.random());
frobState(Symbol())
}, [items]);
</code></pre>
<p>But I'm wondering if there's a better way that doesn't require extra state references. </p>

How to properly terminate strings in C programming? : <p>I'm using scanf to scan 5 product names and store them in a string. However, when i print them, the last one is always printed as ♣. Where am i going wrong ?</p>
<p>I am trying to take in the id, name and prices of 5 products and print them using structures. However the last product name is always printed as ♣. I realised that this may be due to improper terminating of the string, and tried the solutions provided to such questions.
I saw another similar question on strings and tried to terminate the string properly by doing, char name[50]={'0'}; in my code. This part is within the structure part of the code.</p>
<pre><code>struct product
{
int id;
char name[50];
int price;
};
void main()
{
struct product p [5];
int i,a;
for(i=1;i<=5;i++)
{
printf("Enter the id no., name and price of the product %d\n",i);
scanf("%d%s%d",&p[i].id,&p[i].name,&p[i].price);
}
printf("The id no., name and price of the product %d are\n",i);
for(i=1;i<=5;i++)
{
printf("\t%d\t%s/0\t%d\n",p[i].id,p[i].name,p[i].price);
}
}
</code></pre>
<p>The final output, that is p[5].name ,should've been what i had entered, but is, however, ♣.
And if i try to terminate the code by entering: char name[50]={'\0'};
it puts up an error message over the '=' saying that it expected a ';'.</p>

hash table with chaining within the table : <p>I have this assignment to complete. (I am new to java). I started to think about it and establish a plan. I am not looking for the answers just a feedback on my approach. I am supposed to enter integers into a hash table using a chaining scheme within the hash table (different from the regular chaining scheme). My idea is to use an arraylist so I can store data + pointer in each slot of the hash table. when a collision occurs, find an empty slot, insert the new integer and set the pointer from the original hashed slot to this new position in the arraylist. This way I am building a sort of linked list within the array. does that make sense? there is a hint about keeping track of the free space with a stack... here I have to say I am not sure how to use the stack in that instance</p>

SimpleCart, SQL and MVC : <p>I have a product table in my sql database with one of the fields named productQuantity. I am using simpleCart which saves alot of manual coding. One such feature is the simpleCart.increment which increases the quantity of the item in the cart. </p>
<p>However I am now having an issue of whereby if there is 5 items in stock the increment goes pass the 5th item.</p>
<p>How do I limit the customer from increasing the quantity if the customer wants to purchase all five items and for example mistakenly increments to 6 items.</p>

C++ Can't Return A Vector of Textures : <p>I have a class that keeps track of objects I've declared. This class also has a vector as a member. I add textures through a function (probably, there is a leak). I am probably doing a mistake about c++ itself, not sfml.</p>
<p>in Item.h:</p>
<pre><code> #ifndef ITEM_H
#define ITEM_H
class ItemTexture {
public:
static std::vector<ItemTexture*> textures;
std::vector<sf::Texture*> variation;
ItemTexture(std::string file);
void addTexture(std::string file);
static sf::Texture getTexture(int id, int no) {
return *textures[id]->variation[no]; //Program crashes here
}
static void declare_textures();
};
#endif
</code></pre>
<p>in the Item.cpp:</p>
<pre><code>#include "Item.h"
std::vector<ItemTexture*> ItemTexture::textures;
ItemTexture::ItemTexture(std::string file)
{
sf::Texture *tex = new sf::Texture;
tex->setSmooth(false);
tex->loadFromFile(file);
variation.push_back(tex);
textures.push_back(this);
delete tex;
}

{
sf::Texture *tex = new sf::Texture;
tex->setSmooth(false);
tex->loadFromFile(file);
variation.push_back(tex);
delete tex;
}

<p>This doesn't give any error messages, program crashes at the line return *textures[id]->variation[no];</p>

formatting string to a number : <p>I am parsing a string with text and numbers in it e.g. abc00123.</p>
<p>When i extract numbers 00123 it is still a string so i cast to a double.</p>
<p>After i do this it it loses the zeros at the beginning of this.</p>
<p>Also the length of the numbers can vary.</p>
<p>Is there anyway to keep the zero when casting the string to a double ?</p>
<p>if not maybe i will compare the two strings and if the size of the original array is bigger append the differences onto the beginning of the number if possible?</p>
<p>Thanks in advance for the help.</p>

What is the difference between type, value_type and element_type, and when to use each? : <p>I have written a template class that should expose its template parameter, but I am unsure of the appropriate naming.</p>
<p>I have found three different names for essentially the same thing (as far as I can tell):</p>
<ul>
<li>containers, e.g., <code>std::vector</code> use <code>value_type</code></li>
<li>smart pointers, e.g., <code>std::unique_ptr</code> use <code>element_type</code></li>
<li><code>std::reference_wrapper</code> uses just <code>type</code></li>
</ul>
<p>What is the idea behind these different names? What standard algorithms or trait classes depend on which name? Which name should I use for my class (something in between a smart pointer and reference wrapper)?</p>

<p>I went into the directory in the error and I realized there is really no <code>postgis.control</code> inside <code>9.5</code></p>
<p>I checked my psql version and showed 9.6.1</p>
<p>I went into <code>9.6</code> folder and I DO see a <code>postgis.control</code> in it.</p>
<p>I want to changed the installation directory so when i run</p>
<p><code>create extension postgis</code></p>
<p>it would go</p>
<p><code>"/usr/share/postgresql/9.6/extension/postgis.control"</code></p>
