RISKY BUSINESS RATING: 7 /10 -->Good movie

PLOT: Rich kid preparing for College suddenly finds himself all alone in the house as his parents leave for a trip. When one of his friends suggests that he loosen up, he turns that piece of advice into a money-making scheme, featuring escort call girls and his friends trading favors for one another, in a wild night of drinks, sex and debauchery.
CRITIQUE: Tom Cruise's breakthrough feature accentuates the rebellion of youth intertwined with the trepidation of a future unknown. A darker, sexier FERRIS BUELLER'S DAY OFF, if you will. And if you won't, you could see this film as an interesting character study of a kid torn between his tendencies to discover the wild side of life before adult responsibilities and his desire to satisfy his parents. I liked it mostly on nostalgic grounds with Cruise coming across as the perfect boy next door with that certain twinkle in his eye, and sunglasses that were just waaaay too big for his face. Having said that, Ray-Ban isn't complaining since this film's success literally quadrupled their sales the next year. This film also features the classic scene of Cruise dancing around in his white briefs and preppy shirt to the tune of "Old Time Rock n' Roll".
Overall, it was unique enough to keep me interested throughout, despite the tepid romance scenes between Cruise and DeMornay and the farfetched nature of some of its scenarios. If you like Cruise, you should see this film at least one, or if you're also in the midst of interrogating your life decisions right before College. All in all, despite its dated feel, this film has an interesting premise, great style and good acting.
Little Known Facts about this film and its stars: This film garnered actor Tom Cruise a 1984 Golden Globe nomination for Best Performance by an Actor in a Motion Picture- Comedy/Musical. He lost it to Michael Caine for EDUCATING RITA. The top of Tom's head is apparently 5'7" from ground level. This film grossed $63.5M upon its release in 1983. This was writer/director Paul Brickman's first time behind the camera. He only directed one other film after this one, and it was 1990's MEN DON'T LEAVE. The only other film he wrote after this one was 1999's TRUE CRIME (5.5/10). The "bad guy" character of Guido in this film is played by actor Joe Pantoliano. He recently starred as "Cypher" in the 1999 Sci-Fi classic THE MATRIX (7.5/10). Actress Rebecca DeMornay's birth name is Rebecca George. She changed her last name so that she would not be connected to her father. She was raised in France, went to high school and College in Europe and speaks fluent German.

I should read docs before asking questions.
Though I still have a question: how hard is it to make conv
aware of ext
? Now I can call funext
to enter a function but it would be nice to be able to call ext
to enter anything.
Actually, I think congr
or to_args
or whatever it is called should do this
ext
doesn't make as much sense inside conv
since most extensionality lemmas don't have the right form
congr
doesn't.
funext
worked but it doesn't allow me to name the new variable.
that's odd
intro
is also a reasonable synonym here
I think the story for navigating terms in conv
needs improvement on the whole. to_lhs
and to_rhs
aren't nearly enough
Here are the basic conv tactics I can see a use for. I've tried to borrow names when the tactics have a similar effect, but the underlying theorems are often quite different. It's hard to say which drives the mental model more.
arg i
: enter the i
-th nondependent argument of an application, intro
on bindersargs
: enter all nondependent arguments of an applicationleft
, to_lhs
: synonym for arg n-2
right
, to_rhs
: synonym for arg n-1
intro x
, ext x
, funext x
: enter the body of a pi or lambda.intros
: same repetition behavior as intros
tacticapply h
: rewrite the entire goal with h
by transitivityrw h
: rewrite with h
somewhere in the goalenter [1,3,x,y]
: iterate arg
and intro
with the given argumentspattern (_+_)
: find the first matching subterm (in top down left right order)Many of these already have equivalent functions, but I think we should try to organize the whole set and bikeshed on names until this is as usable as regular tactic mode
One reason why I don't use conv
mode that much is that it seems to me it is often quite slow and not so responsive... do others recognise this?
It shouldn't be any slower than any other tactic; what conv
does in its most basic mode is extremely simple, essentially just apply eq.mp
More conv tactics:
convert y
: produce a subgoal |- goal = y
in regular tactic modetrans y
: produce a tactic subgoal |- goal = y
and a conv subgoal | y
tactic { tac }
: use a regular tactic as a conv tactic (the tactic sees the goal |- goal = ?m1
). (This is the identity function under the hood)done
, refl
: close the goal by reflexivity (should be optional most of the time)Please don't make intro
different from intros
.

ally.js provides the method ally/focus/within
to "polyfill" the pseudo-class
:focus-within
.
Since we cannot (easily) shim pseudo-classes, this function applies the class ally-focus-within
to all the elements that would match :focus-within
. This method pierces the ShadowDOM and works with SVG.
In Firefox the setting dom.webcomponents.enabled
needs to be set to true
to enable ShadowDOM support.
Firefox 34 does not expose ShadowRoot.host
, coupled with document.activeElement
pointing to the wrong element,
we cannot find the first ShadowHost and can thus not apply focus-within
properly.
The ShadowRoot.host
issue has been fixed in Firefox 37 (at the latest).
// load focus/within var focusWithin = require('ally/focus/within'); // activate focus-within "polyfill" var disengage = focusWithin(); // stop focus-within "polyfill" disengage();
The ancestry of the focused element should be visible by red borders.
The first and the last input are outside of the style scope - they are there to provide
focusable elements to verify that the ally-focus-within
class is properly removed.

From:
https://www.governor.ny.gov/news/governor-cuomo-signs-new-york-state-pause-executive-order
Governor Andrew M. Cuomo "We know the most effective way to reduce the spread of this virus is through social distancing and density reduction measures," Governor Cuomo said. "I have said from the start that any policy decision we make will be based on the facts, and as we get more facts we will calibrate our response accordingly. This executive order builds on the actions we have taken to reduce the spread of the virus and protect the wellbeing of our friends, colleagues and neighbors. But again, I want to remind New Yorkers that the panic we are seeing is outpacing the reality of the virus — and we will get through this period of time together."
The Governor's 10-point NYS on PAUSE plan is as follows:
Effective at 8PM on Sunday, March 22, all non-essential businesses statewide will be closed;
Non-essential gatherings of individuals of any size for any reason (e.g. parties, celebrations or other social events) are canceled or postponed at this time;
Any concentration of individuals outside their home must be limited to workers providing essential services and social distancing should be practiced;
When in public individuals must practice social distancing of at least six feet from others;
Businesses and entities that provide other essential services must implement rules that help facilitate social distancing of at least six feet;
Individuals should limit outdoor recreational activities to non-contact and avoid activities where they come in close contact with other people;
Individuals should limit use of public transportation to when absolutely necessary and should limit potential exposure by spacing out at least six feet from other riders;
Sick individuals should not leave their home unless to receive medical care and only after a telehealth visit to determine if leaving the home is in the best interest of their health;
Young people should also practice social distancing and avoid contact with vulnerable populations; and Use precautionary sanitizer practices such as using isopropyl alcohol wipes.
"Matilda's Law" includes the following rules for vulnerable populations:
Remain indoors;
Can go outside for solitary exercise;
Pre-screen all visitors and aides by taking their temperature and seeing if person is exhibiting other flu-like symptoms;
Do not visit households with multiple people;
Wear a mask when in the company of others;
To the greatest extent possible, everyone in the presence of vulnerable people should wear a mask;
Always stay at least six feet away from individuals; and
Do not take public transportation unless urgent and absolutely necessary.


The adapter can be used in a event driven fashion. Volumio can notify via POST calls when state changes.
This is a much more efficient and elegant way to retrieve informations, instead of continuously polling the relevant information.

Alfa Romeo Giulia Stars In Crazy Michael Bay Car Chase
New clip for Michael Bay’s upcoming Netflix movie ‘6 Underground' is action-packed.
by Martin BiggFrom 'Bad Boys 2' and 'The Rock' to the 'Transformers' movies, Michael Bay has directed some of the most destructive chases in cinema history. And now the bombastic director is making a comeback with his new Netflix movie '6 Underground.' Starring Ryan Reynolds, the film is about six billionaires who fake their own deaths and form a vigilante squad to take down criminals.
With a reported budget of $150 million, '6 Underground' is the most expensive Netflix film ever made, and it certainly shows when you watch the film's action-packed trailer. Of course, the standout scene for us in the trailer was a tire-shredding car chase starring the gorgeous Alfa Romeo Giulia Quadrifoglio tearing through the narrow streets of Florence, Italy.
You Might Also Like
In the first trailer, we got a brief glimpse of the chase in a few short clips. With less than a month until the film is released on Netflix, a second trailer for '6 Underground' has dropped online. And much to our delight, the video focuses almost entirely on the film's automotive action.
The trailer opens with a tongue-in-cheek tour of Florence's famous landmarks and architecture before the Giulia Quadrifoglio disturbs the peace by burning lots of rubber in the streets while being chased by several cars and motorcycles. If you don't want to look conspicuous, a sports sedan finished in bright green probably isn't a wise choice, which Ryan Reynolds' character mocks for "blending right into the Italian architecture."
We get to see the sports sedan drift around monuments, crash through a museum, and damage lots of property. In one comedic scene, the Giulia narrowly avoids destroying the statue of David, much to Ryan Reynolds' character's disapproval. It also wouldn't be a Michael Bay movie without some gratuitous slow-mo shots and copious amounts of carnage. In one scene, a Maserati Quattroporte crashes into the back of a van at high speed, causing it to roll over down the street in a shower of sparks.
From the footage we've seen so far, we're expecting '6 Underground' to rank highly in our annual "best movie car chases" feature later this year. '6 Underground' will stream on Netflix on December 13.

It looks like my first SD card is getting a bit flaky (about 5 months wear).
The problem I had was moving the image onto a new SD card. I made the mistake of popping in a 16GB SD card and then expanding the file system to fill it. To compound the issue I have run into the same problem as lots others - 16GB (etc) is not the same on all cards.
The goal was to drop the image size to, say, 7.5Gb so I can use any 8GB or greater card and then just use Win32 Disk Imager to back up/restore images.
A lot of Googling later I found myself at a dead end. I could reduce the partition size (GParted worked as did a couple of Windows based backup/partition managers) - the issue was Win32 Disk Imager would always create a 16GB (etc) image as it dumps the full card regardless of whether there was any data in a partition. So your X GB card always produces an X GB image - and as SD cards seem to be a few bytes different even if the same brand/type then Win32 Disk Imager will give you a "cannot fit" type of error.
It looked like my only option was going to be running DD in a Linux environment - maybe Ubuntu live on a USB keydrive. Before I went this route I thought I would have a quick look at some back up software options I had installed to see if any of them was happy with reading Linux partitions.
I struck lucky first time with AOMEI Backupper (a cuddlier front end to the AOMEI freeware disk cloning/ partitioning software). By now I had already shrunk the partition to around 7GB using GParted on a boot CD , however, I have used AOMEI before to do this. I did a backup of the 16GB card and simply restored the image to an 8GB SD card.
For the restore I only restored the Boot (FAT32) and Data (Linux) partitions leaving out the unallocated space created when I reduced the Data partition beforehand. A quick finger-cross later and it seems to be working.
Reducing your RPi SD card image size using AOMEI Backupper on Windows (8.1 but sure 7 onwards OK)

Los Angeles Houseless Rates on the Rise. Solution is Obvious, study says
Luskin Institute and Democracy at UCLA published a new report in July titled "Hotel California: Housing the Crisis" urging Los Angeles to aquire vacant hotels and motels and convert them into permanent housing for the city's 60,000 unhoused residents.
By aquiring empty hotel and motel units, LA can also create housing for the thousands on the verge of eviciton, the study says.
“It is time to redirect public resources and public purpose tools such as eminent domain for low-income and extremely low-income housing, especially in Black and brown communities where public investment has primarily taken the form of policing,” says Gary Blasi, UCLA professor emeritus of Law and co-author of the report.
The report details the six ZIP codes most at-risk for eviction when moratoriums end on Jan 1 2021. These ZIP codes are also predominatley Black and brown. Without public intervention, houselessness will increase the already disproportionate numbers for these communities. While LA allocates $500 million, Jane Nguyen, Co-Founder of Ktown for All, says $80 million of that fund goes to LAPD. Echoing Blasi's observations that the city has largely invests in the criminalization of poverty, instead of housing.
"It's a matter of priority," says the housing advocate. "Los Angels city council just voted to resume CDC defying sweeps. Even in a pandemic the city is terrorizing our unhoused neighbors and potentially spreading the virus while doing it." The $80 million dollars could be converterd into more than 1,000 units of housing at the average cost of about $80,000 per unit. In sum, the study asserts the solution to houselessness in Los Angeles is publically aquired, permanant housing. As outlined in the map below, the reaollocation of LAPD funds would cover half then necessary housing neede to prevent the pending increase of houselessness in these six at-risk zip codes. The reallocation would not disturb the LAPD general budget, which is set at more than $3 billion for 2020-2021.

There can be times when you are asked to do the impossible, thats what we do as developers, we are super-humans and our kryptonite is caffeine.
Recently, I came across a project in which I was supposed to modify the Http headers of the request going to a different server. Like a superhuman, I thought it was a piece of cake; But after a lot of brainstorming, brute-forcing and caffeine intake I realized it wasn’t that simple. In-fact it was not possible at all. Now, before you folks get mad and swear at me, let me explain you the problem and how I tried to solve it, how miserably I failed and finally how I got around it by a simple trick.
Problem:
Let us start with the problem. What I had to do was simple, upon a user event (assume a mouse click) I needed to calculate a value and insert it into the header of a new request. Note the ‘new request’ here. This new request is not on the same server but on a different server where I have very little control.
Conclusion:
I spent considerable amount of time working on this problem, if only I knew the simple answer to the question, it would have saved me so much of time. The answer was simply you cannot do it ! you cannot change the headers of the request which is redirected to a different server.
But why ?
The reason is that if you were able to modify the headers you could intercept the user requests in what ever way you want. There would be a high probability of man-in-the-middle attack. One of the many ingenious way of Java to protect you.
Workaround:
The work around was to encrypt the information in the url and send it, or use a form or hidden field.
Using HttpServletRequestWrapper class:
If you want to modify the headers of the request which is on the same server then it can be done by overriding the getHeaderName and getHeader of the HttpServletRequestWrapper class. Now, if you are curious like me you might ask why on the earth do I want to use a wrapper class ? Why cannot I simply use a filter to modify the headers. As it appears, when you redirect or for that matter forward a request your headers are committed and the stream is closed by using the HttpServletRequestWrapper class you can tell the servlet to stand by before committing the response so that we can modify the headers. Enough of theory lets gets some coding done.
In the rest of the blog I will explain how to modify the headers by overriding the HttpServletRequestWrapper class.
Assumptions
Here, I am assuming you are familiar with the basics of J2EE filter and have already set up one for testing this example. Filter example is a good filter example to start with.
Once you have set up a filter, lets call it MyFilterExample, it should look pretty much like the following code.
package com.sandeepmore.filters; import java.io.IOException; import javax.servlet.*; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; import javax.servlet.http.HttpServletResponseWrapper; import javax.servlet.http.HttpSession; import java.util.logging.*; public class MyFilterExample implements javax.servlet.Filter { private ServletContext servletContext; private Logger log; public MyFilterExample(){ super(); } public void init(FilterConfig filterConfig) throws ServletException { servletContext = filterConfig.getServletContext(); log = Logger.getLogger(MyFilter.class.getName()); } public void doFilter( ServletRequest req, ServletResponse res, FilterChain filterChain) throws IOException, ServletException { MyServletRequestWrapper httpReq = new MyServletRequestWrapper((HttpServletRequest)req); HttpServletResponse httpRes = (HttpServletResponse)res; HttpSession session = httpReq.getSession(); httpReq.addHeader("myHeader", "value"); filterChain.doFilter(httpReq, httpRes); } public void destroy(){ } }
As you can see we have added our custom headers using the line
httpReq.addHeader("myheader", "value");
The entire meat is in the method doFilter(). In the above class this is the only method which needs to be modified as shown above. All we did in this method is wrapped the http request object with the MyServletRequestWrapper class (which we are about to see in a while) so that we can override the getHeaderName and getHeader methods and insert our custom headers. Code for MyServletRequestWrapper class is as follows
package myfilter; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletRequestWrapper; import java.util.*; public class MyServletRequestWrapper extends HttpServletRequestWrapper{ private Map headerMap; public void addHeader(String name, String value){ headerMap.put(name, new String(value)); } public MyServletRequestWrapper(HttpServletRequest request){ super(request); headerMap = new HashMap(); } public Enumeration getHeaderNames(){ HttpServletRequest request = (HttpServletRequest)getRequest(); List list = new ArrayList(); for( Enumeration e = request.getHeaderNames() ; e.hasMoreElements() ; ) list.add(e.nextElement().toString()); for( Iterator i = headerMap.keySet().iterator() ; i.hasNext() ; ){ list.add(i.next()); } return Collections.enumeration(list); } public String getHeader(String name){ Object value; if((value = headerMap.get(""+name)) != null) return value.toString(); else return ((HttpServletRequest)getRequest()).getHeader(name); } }
All this class does is that it adds the new header and the value associated with it to a Hashmap, ‘headerMap’ in our case. When the getHeaderNames method is called the new headers are inserted into a ArrayList and returned as a Enumeration.
The getHeader method searches for the header value in Hashmap ‘headerMap’ first then it checks the HttpServletRequest object for the header information.
This is a very simple trick and can be very handy. Again, one important thing to remember this method is useful only if you are forwarding a request on the same server and not ‘redirecting’ to a different server.
Happy Coding

Potential Issues/Advanced Topics/Future Features in Physics/Vector Module¶
This document will describe some of the more advanced functionality that this module offers but which is not part of the “official” interface. Here, some of the features that will be implemented in the future will also be covered, along with unanswered questions about proper functionality. Also, common problems will be discussed, along with some solutions.
Inertia (Dyadics)¶
A dyadic tensor is a second order tensor formed by the juxtaposition of a
pair of vectors. There are various operations defined with respect to dyadics,
which have been implemented in vector
in the form of class
Dyadic
. To know more, refer to the Dyadic
and Vector
class APIs.
Dyadics are used to define the inertia of bodies within mechanics
.
Inertia dyadics can be defined explicitly but the inertia
function is
typically much more convenient for the user:
>>> from sympy.physics.mechanics import ReferenceFrame, inertia
>>> N = ReferenceFrame('N')
Supply a reference frame and the moments of inertia if the object
is symmetrical:
>>> inertia(N, 1, 2, 3)
(N.x|N.x) + 2*(N.y|N.y) + 3*(N.z|N.z)
Supply a reference frame along with the products and moments of inertia
for a general object:
>>> inertia(N, 1, 2, 3, 4, 5, 6)
(N.x|N.x) + 4*(N.x|N.y) + 6*(N.x|N.z) + 4*(N.y|N.x) + 2*(N.y|N.y) + 5*(N.y|N.z) + 6*(N.z|N.x) + 5*(N.z|N.y) + 3*(N.z|N.z)
Notice that the inertia
function returns a dyadic with each component
represented as two unit vectors separated by a |
. Refer to the
Dyadic section for more information about dyadics.
Inertia is often expressed in a matrix, or tensor, form, especially for numerical purposes. Since the matrix form does not contain any information about the reference frame(s) the inertia dyadic is defined in, you must provide one or two reference frames to extract the measure numbers from the dyadic. There is a convenience function to do this:
>>> inertia(N, 1, 2, 3, 4, 5, 6).to_matrix(N)
Matrix([
[1, 4, 6],
[4, 2, 5],
[6, 5, 3]])
Common Issues¶
Here issues with numerically integrating code, choice of \(dynamicsymbols\) for coordinate and speed representation, printing, differentiating, and substitution will occur.
Printing¶
The default printing options are to use sorting for Vector
and Dyadic
measure numbers, and have unsorted output from the vprint
, vpprint
, and
vlatex
functions. If you are printing something large, please use one of
those functions, as the sorting can increase printing time from seconds to
minutes.
Substitution¶
Substitution into large expressions can be slow, and take a few minutes.
Acceleration of Points¶
At a minimum, points need to have their velocities defined, as the acceleration can be calculated by taking the time derivative of the velocity in the same frame. If the 1 point or 2 point theorems were used to compute the velocity, the time derivative of the velocity expression will most likely be more complex than if you were to use the acceleration level 1 point and 2 point theorems. Using the acceleration level methods can result in shorted expressions at this point, which will result in shorter expressions later (such as when forming Kane’s equations).
Advanced Interfaces¶
Here we will cover advanced options in: ReferenceFrame
, dynamicsymbols
,
and some associated functionality.
ReferenceFrame¶
ReferenceFrame
is shown as having a .name
attribute and .x
, .y
,
and .z
attributes for accessing the basis vectors, as well as a fairly
rigidly defined print output. If you wish to have a different set of indices
defined, there is an option for this. This will also require a different
interface for accessing the basis vectors.
>>> from sympy.physics.vector import ReferenceFrame, vprint, vpprint, vlatex
>>> N = ReferenceFrame('N', indices=['i', 'j', 'k'])
>>> N['i']
N['i']
>>> N.x
N['i']
>>> vlatex(N.x)
'\\mathbf{\\hat{n}_{i}}'
Also, the latex output can have custom strings; rather than just indices though, the entirety of each basis vector can be specified. The custom latex strings can occur without custom indices, and also overwrites the latex string that would be used if there were custom indices.
>>> from sympy.physics.vector import ReferenceFrame, vlatex
>>> N = ReferenceFrame('N', latexs=['n1','\mathbf{n}_2','cat'])
>>> vlatex(N.x)
'n1'
>>> vlatex(N.y)
'\\mathbf{n}_2'
>>> vlatex(N.z)
'cat'
dynamicsymbols¶
The dynamicsymbols
function also has ‘hidden’ functionality; the variable
which is associated with time can be changed, as well as the notation for
printing derivatives.
>>> from sympy import symbols
>>> from sympy.physics.vector import dynamicsymbols, vprint
>>> q1 = dynamicsymbols('q1')
>>> q1
q1(t)
>>> dynamicsymbols._t = symbols('T')
>>> q2 = dynamicsymbols('q2')
>>> q2
q2(T)
>>> q1
q1(t)
>>> q1d = dynamicsymbols('q1', 1)
>>> vprint(q1d)
q1'
>>> dynamicsymbols._str = 'd'
>>> vprint(q1d)
q1d
>>> dynamicsymbols._str = '\''
>>> dynamicsymbols._t = symbols('t')
Note that only dynamic symbols created after the change are different. The same is not true for the \(._str\) attribute; this affects the printing output only, so dynamic symbols created before or after will print the same way.
Also note that Vector
‘s .dt
method uses the ._t
attribute of
dynamicsymbols
, along with a number of other important functions and
methods. Don’t mix and match symbols representing time.


public interface MemoryPoolMXBean extends PlatformManagedObject
memory managers
.
A Java virtual machine has one or more instances of the
implementation class of this interface. An instance
implementing this interface is
an MXBean
that can be obtained by calling
the ManagementFactory.getMemoryPoolMXBeans()
method or
from the platform MBeanServer
method.
The ObjectName for uniquely identifying the MXBean for a memory pool within an MBeanServer is:
java.lang:type=MemoryPool
,name=pool's name
It can be obtained by calling the
PlatformManagedObject.getObjectName()
method.
The Java virtual machine has a heap for object allocation and also maintains non-heap memory for the method area and the Java virtual machine execution. The Java virtual machine can have one or more memory pools. Each memory pool represents a memory area of one of the following types:
getUsage()
method provides an estimate
of the current usage of a memory pool.
For a garbage-collected memory pool, the amount of used memory
includes the memory occupied by all objects in the pool
including both reachable and unreachable objects.
In general, this method is a lightweight operation for getting an approximate memory usage. For some memory pools, for example, when objects are not packed contiguously, this method may be an expensive operation that requires some computation to determine the current memory usage. An implementation should document when this is the case.
getPeakUsage()
method
and reset by calling the resetPeakUsage()
method.
setUsageThreshold
method.
If the threshold is set to a positive value, the usage threshold crossing
checking is enabled in this memory pool.
If the usage threshold is set to zero, usage
threshold crossing checking on this memory pool is disabled.
The isUsageThresholdSupported()
method can
be used to determine if this functionality is supported.
A Java virtual machine performs usage threshold crossing checking on a
memory pool basis at its best appropriate time, typically,
at garbage collection time.
Each memory pool maintains a usage threshold count
that will get incremented
every time when the Java virtual machine
detects that the memory pool usage is crossing the threshold.
This manageable usage threshold attribute is designed for monitoring the increasing trend of memory usage with low overhead. Usage threshold may not be appropriate for some memory pools. For example, a generational garbage collector, a common garbage collection algorithm used in many Java virtual machine implementations, manages two or more generations segregating objects by age. Most of the objects are allocated in the youngest generation (say a nursery memory pool). The nursery memory pool is designed to be filled up and collecting the nursery memory pool will free most of its memory space since it is expected to contain mostly short-lived objects and mostly are unreachable at garbage collection time. In this case, it is more appropriate for the nursery memory pool not to support a usage threshold. In addition, if the cost of an object allocation in one memory pool is very low (for example, just atomic pointer exchange), the Java virtual machine would probably not support the usage threshold for that memory pool since the overhead in comparing the usage with the threshold is higher than the cost of object allocation.
The memory usage of the system can be monitored using polling or threshold notification mechanisms.
An application can continuously monitor its memory usage
by calling either the getUsage()
method for all
memory pools or the isUsageThresholdExceeded()
method
for those memory pools that support a usage threshold.
Below is example code that has a thread dedicated for
task distribution and processing. At every interval,
it will determine if it should receive and process new tasks based
on its memory usage. If the memory usage exceeds its usage threshold,
it will redistribute all outstanding tasks to other VMs and
stop receiving new tasks until the memory usage returns
below its usage threshold.
// Assume the usage threshold is supported for this pool. // Set the threshold to myThreshold above which no new tasks // should be taken. pool.setUsageThreshold(myThreshold); .... boolean lowMemory = false; while (true) { if (pool.isUsageThresholdExceeded()) { // potential low memory, so redistribute tasks to other VMs lowMemory = true; redistributeTasks(); // stop receiving new tasks stopReceivingTasks(); } else { if (lowMemory) { // resume receiving tasks lowMemory = false; resumeReceivingTasks(); } // processing outstanding task ... } // sleep for sometime try { Thread.sleep(sometime); } catch (InterruptedException e) { ... } }
getUsageThresholdCount()
method
can be used to determine
if the memory usage has returned below the threshold
between two polls.
Below shows another example that takes some action if a memory pool is under low memory and ignores the memory usage changes during the action processing time.
// Assume the usage threshold is supported for this pool. // Set the threshold to myThreshold which determines if // the application will take some action under low memory condition. pool.setUsageThreshold(myThreshold); int prevCrossingCount = 0; while (true) { // A busy loop to detect when the memory usage // has exceeded the threshold. while (!pool.isUsageThresholdExceeded() || pool.getUsageThresholdCount() == prevCrossingCount) { try { Thread.sleep(sometime) } catch (InterruptException e) { .... } } // Do some processing such as check for memory usage // and issue a warning .... // Gets the current threshold count. The busy loop will then // ignore any crossing of threshold happens during the processing. prevCrossingCount = pool.getUsageThresholdCount(); }
Usage threshold notification will be emitted by MemoryMXBean
.
When the Java virtual machine detects that the memory usage of
a memory pool has reached or exceeded the usage threshold
the virtual machine will trigger the MemoryMXBean to emit an
usage threshold exceeded notification
.
Another usage threshold exceeded notification will not be
generated until the usage has fallen below the threshold and
then exceeded it again.
Below is an example code implementing the same logic as the first example above but using the usage threshold notification mechanism to detect low memory conditions instead of polling. In this example code, upon receiving notification, the notification listener notifies another thread to perform the actual action such as to redistribute outstanding tasks, stop receiving tasks, or resume receiving tasks. The handleNotification method should be designed to do a very minimal amount of work and return without delay to avoid causing delay in delivering subsequent notifications. Time-consuming actions should be performed by a separate thread. The notification listener may be invoked by multiple threads concurrently; so the tasks performed by the listener should be properly synchronized.
class MyListener implements javax.management.NotificationListener { public void handleNotification(Notification notification, Object handback) { String notifType = notification.getType(); if (notifType.equals(MemoryNotificationInfo.MEMORY_THRESHOLD_EXCEEDED)) { // potential low memory, notify another thread // to redistribute outstanding tasks to other VMs // and stop receiving new tasks. lowMemory = true; notifyAnotherThread(lowMemory); } } } // Register MyListener with MemoryMXBean MemoryMXBean mbean = ManagementFactory.getMemoryMXBean(); NotificationEmitter emitter = (NotificationEmitter) mbean; MyListener listener = new MyListener(); emitter.addNotificationListener(listener, null, null); // Assume this pool supports a usage threshold. // Set the threshold to myThreshold above which no new tasks // should be taken. pool.setUsageThreshold(myThreshold); // Usage threshold detection is enabled and notification will be // handled by MyListener. Continue for other processing. ....
There is no guarantee about when the MemoryMXBean will emit
a threshold notification and when the notification will be delivered.
When a notification listener is invoked, the memory usage of
the memory pool may have crossed the usage threshold more
than once.
The MemoryNotificationInfo.getCount()
method returns the number
of times that the memory usage has crossed the usage threshold
at the point in time when the notification was constructed.
It can be compared with the current usage threshold count returned
by the getUsageThresholdCount()
method to determine if
such situation has occurred.
collection usage threshold exceeded notification
will be emitted by the MemoryMXBean
.
In addition, the collection usage threshold count
will then be incremented.
The isCollectionUsageThresholdSupported()
method can
be used to determine if this functionality is supported.
A Java virtual machine performs collection usage threshold checking on a memory pool basis. This checking is enabled if the collection usage threshold is set to a positive value. If the collection usage threshold is set to zero, this checking is disabled on this memory pool. Default value is zero. The Java virtual machine performs the collection usage threshold checking at garbage collection time.
Some garbage-collected memory pools may choose not to support the collection usage threshold. For example, a memory pool is only managed by a continuous concurrent garbage collector. Objects can be allocated in this memory pool by some thread while the unused objects are reclaimed by the concurrent garbage collector simultaneously. Unless there is a well-defined garbage collection time which is the best appropriate time to check the memory usage, the collection usage threshold should not be supported.
The collection usage threshold is designed for monitoring the memory usage after the Java virtual machine has expended effort in reclaiming memory space. The collection usage could also be monitored by the polling and threshold notification mechanism described above for the usage threshold in a similar fashion.

MemoryUsage getUsage()
This method requests the Java virtual machine to make a best-effort estimate of the current memory usage of this memory pool. For some memory pools, this method may be an expensive operation that requires some computation to determine the estimate. An implementation should document when this is the case.
This method is designed for use in monitoring system memory usage and detecting low memory condition.

Close calls as Joe Worrall picks his Nottingham Forest team of the decade
Nottingham Forest latest | We've been asking for your Forest team of the past 10 years - and Reds defender Joe Worrall has chipped in with his favourite players of the decade
by Josh MurrayJoe Worrall has picked his Nottingham Forest team of the decade - and it features two of his current teammates.
With less than two months remaining of 2019, we at Nottinghamshire Live have been asking Reds fans to select their fantasy Forest XI of the last 10 years.
Centre-back Worrall - who joined the club aged 14 - has had his say, although he has not selected himself in the team.
Instead, he has gone with a central defensive partnership of Jack Hobbs - who made 86 appearances for Forest between 2013 and 2018 - and current captain Michael Dawson, into his second spell at the club.
The other member of Sabri Lamouchi's squad who makes the fantasy XI is goalkeeper Brice Samba.
Worrall's full Forest team of the decade has a back four of Eric Lichaj, Hobbs, Dawson and Chris Cohen across the back four, with David Vaughan in defensive midfield and Ben Osborn and Henri Lansbury as the other central midfielders.
Michail Antonio is on the right wing, Andy Reid takes the left-wing spot and Britt Assombalonga - the scorer of 30 Championship goals in 65 appearances - leads the line up front.
Worrall's tweet also sheds light on a trio of players that came close to making his team.
"[Wes] Morgan/Hobbs tight. Raddy (Radoslaw Majewski) and [Lewis] McGugan would love to squeeze either in as watching them growing up was awesome, but HL and BO class to play with."

Show went well. Twas great really. Mahle (Sybris) did sound again. It turns out, he did sound for a show we (one of my bands) did with System and Station a long time ago at the Prodigal Son when it was being booked by Brian of MPshows.
We swapped out the Silkworm song in the set, Cockfight of Feelings, for a song from the sepi sessions, Heliocentric Model. Dean (now of Chevelle fame) helped me re-arrange the song and it can be quite challenging, so we decided to wait until this second show to trot it out like the racehorse it is. Surprisingly, we did quite well with it.
The other bands were good too, ST Monroe and Archaeology, but System and Station rocked!  They’ve got a new bass player and drummer, both swell guys, and Ryan and Palmer were both just ripping it up.  Dan Fanelli and I were talking about how the new drummer is such a pro. And the bass player was wicked intense, like he was one big vein pulsing, about to pop. The new songs sounded great.

Penn State Dealt Unfortunate Injury News Before Ohio State Game
by Chris RosvoglouWhen Penn State takes the field this Saturday against Ohio State, the offense will be missing a key starter. Redshirt junior offensive lineman Michal Menet will not be available to play this weekend.
Menet has been the starting center for the Nittany Lions every game this season. Before his junior campaign even began he was named to the preseason Rimington Trophy Watch List
Penn State will replace Menet with redshirt sophomore Mike Miranda, who typically plays offensive guard. Nonetheless, he’s second on the depth chart at center.
FOX43 Sports first broke the news about Menet being inactive for this weekend with an undisclosed injury.
As a result of this injury, freshman Blake Zalar and redshirt junior Hunter Kelly will most likely move up on the depth chart.
To make matters worse for Penn State, the offensive line will have to block Chase Young. He’s ready to make a statement after missing the last two games due to a suspension.
Since the Nittany Lions will be without Menet this weekend, the pressure is on the rest of the offensive line to step up.
Kickoff for this game is at 12 p.m. ET from Ohio Stadium. The winner of this game would be in first place in the Big Ten East.
