ScriptableObject is a class that allows you to store large quantities of shared data independent from script instances. Do not confuse this class with the similarly named SerializableObject, which is an editor class and fills a different purpose. Consider for example that you have made a prefab with a script which has an array of a million integers. The array occupies 4MB of memory and is owned by the prefab. Each time you instantiate that prefab, you will get a copy of that array. If you created 10 game objects, then you would end up with 40MB of array data for the 10 instances.
Unity serializes all primitive types, strings, arrays, lists, types specific to Unity such as Vector3 and your custom classes with the Serializable attribute as copies belonging to the object they were declared in. This means that if you created a ScriptableObject and stored the million integers in an array it declares then the array will be stored with that instance. The instances are thought to own their individual data. ScriptableObject fields, or any UnityEngine.Object fields, such as MonoBehaviour, Mesh, GameObject and so on, are stored by reference as opposed to by value. If you have a script with a reference to the ScriptableObject with the million integers, Unity will only store a reference to the ScriptableObject in the script data. The ScriptableObject in turn stores the array. 10 instances of a prefab that has a reference to a ScriptableObject, that holds 4MB data, would total to roughly 4MB and not 40MB as discussed in the other example.
The intended use case for using ScriptableObject is to reduce memory usage by avoiding copies of values, but you could also use it to define pluggable data sets. An example of this would be to imagine a NPC shop in a RPG game. You could create multiple assets of your custom ShopContents ScriptableObject, each defining a set of items that are available for purchase. In a scenario where the game has three zones, each zone could offer different tier items. Your shop script would reference a ShopContents object that defines what items are available. Please see the scripting reference for examples.
Once you have defined a ScriptableObject-derived class, you can use the CreateAssetMenu attribute to make it easy to create custom assets using your class.
Tip: When working with ScriptableObject references in the inspector, you can double click the reference field to open the inspector for your ScriptableObject. You can also create a custom Editor to define the look of the inspector for your type to help manage the data that it represents.


All features of { Personal } are controlled by setting values to variables that are defined in the _config.yml file. Let’s start with the initial variables that you have to set before serving your { Personal } website for the first time.
# NB! Set your site's url, otherwise stuff will break :)
url: "https://panossakkos.github.io"
# If you're hosting your site at a Project repository on GitHub pages
# (https://yourusername.github.io/repository-name)
# and NOT your user repository (https://yourusername.github.io)
# then add in the baseurl here, like this: "/repository-name"
#
# NB! Without this *nothing* will work, because it's used in every path :)
baseurl: /personal-jekyll-theme
The url and baseurl variables are essential, because they are used everywhere where an anchor is defined!
You can define the colors that you want in your { Personal } website by setting the following variable sin the /_sass/_variables.scss file:
// Main color
$primary-color: #000;
// Anchor color
$secondary-color: #00cdff;
// Font color
$font-color: #fff;
By default { Personal } will enforce https by javascript redirection. HTTPS is important because it encrypts the data sent between the client and the server. If you are hosting on GitHub Pages then it will just work, because your website will be piggybacking GitHub’s certificate. If you are hosting your website in a server that doesn’t have a certificate and you don’t want to issue one, then you can disable this feature by setting the following variable to False:
force-https: True
lang: "en"
author: "John Smith"
title: "{ John Smith }"
description: "Blog and website of John Smith, blogging mainly for tech. Opinions expressed are mine."
keywords: "smith, jones, personal, jekyll, theme"
favicon: "/img/favicon.ico"
404-img: "/img/labtocat.png"
The values that you set, will be placed in the head section of every generated HTML page.
The Google tracking code will be placed in every generated page. If you don’t want Google analytics tracking your website’s traffic, set the google-tracking-id to an empty string.
google-tracking-id: "UA-35880426-4"
Install the required dependencies:
gem install jekyll jekyll-paginate jemoji html-proofer
Serve the jekyll website:
./scripts/serve-production
That’s it!
Visit http://<IP_ADDRESS>:4000 and you are ready to start hacking around your { Personal } website!
Many thanks to @joariasl for the language support!


Our experiments with society and different people’s ideas of bringing forth the holiest of changes to our motherland have not panned out so far, In fact, considering India’s state today, not just politically, but also on the economic, social and all other fronts, there is little we can boast of whole-heartedly. There is always someone complaining about something in the system. Can we ever attain the dream of utopia? We can at least try! TILT is an attempt at precisely this. We are a group of psyched individuals who have come together to catalyze a change in India, a change for the better! We are not the only people working towards this change but when the wave hits us, our goal is to be a gear in the machine. Are you also tired of listening and not acting? Try being a part of the machine called change. Gear up! Be a catalytic part of tomorrow’s society! Go TILT!
Everyone talks of change and resorts to complaining about what needs to be changed. But as responsible citizens, what can we really do to execute this change that we need to see, effectively? We need to make people aware. Not just aware of the problems. Aware of the plan. The plan to push the nation forward, out of this quagmire that we find ourselves in currently. And how do we do that you may ask. We tell them.
TILT is our , a brainchild of hungry Indians. Indians fed up with the current state of affairs. Indians who are ready to take an extra leap when people generally talk of taking another step. We intend on broadcasting to the nation our intentions and our goals. And we are going to start with the one thing that all of us want more than anything - CHANGE!
Everyone has their methods of tapping at the Goddess of change. We have ours. TILT plans on introducing a magazine of its own that addresses various social issues plaguing the nation as well as issues that need to be told. People who need to be recognized. There is a lot out there that we need to change and we need to know. We will help you with that. Mistake us not for a run-of-the-mill media house. We do not report. We share. We announce. We catalyze change.
In addition to the magazine, TILT will host workshops to revive ancient art forms, improve literacy among underprivileged children, help housewives learn a little English so that they too can be an active part of society. Various events will also be conducted in many cities to spread awareness, and to spread hope. All is not lost. If Indians don’t take responsibility for India, who will?
All of us see people trying hard to welcome change into our lives. We convince people to stop buying fireworks, we tell people not to bribe the traffic policemen, we think we do a lot in the right direction. The problem is, we generally lack either conviction or the momentum to carry on. Prateek and Sumit started this magazine, and later developed it into an organization that will serve as a focal point for everyone’s drive towards the same direction.
When does anyone ever think they’re going to fail when they start off? We kickstarted this organization in the hope that it will culminate into a national movement of sorts. Not just against corruption, but against apathy of the people, against the lackadaisical attitude of the legislature and towards the pillars of change. Change is a very over-used word. We want to run towards this change, not just march towards it. And to do this, we need your help. All Indians must join hands and rise as one nation. Renaissance in the 21st century is here and we’re already a part of it. Come join us.
Contribute to the magazine. Follow our activities, sign up for alerts and newsletters. We’ll keep you posted about events near your city. Participate actively in discussions on the forum and generally, just be aware of the pulse of the nation. Awareness is important because, when the wave hits us, we need to be ready. Ready to direct the wave in the right direction and enjoy the fruits of our labour.

This aims to show the correlation between life/financial satisfaction and what people think is important in life.
Where wave 3 is between 1995-1998, wave 4 1999-2004, wave 5 2005-2009 and wave 6 2010-2014.
I learned a lot during this assignment. This was the first time i was working with D3 which i think was really nice. I can’t say that i am a pro in D3 since we did not have very long time to do this assignment, but I learned that I actually can visualize data in a very cool way now, which i think is great. That makes it so much easy to really see correlations between different variables that you never thought of before.


$().SPServices.SPUpdateMultipleListItems
SPUpdateMultipleListItems allows you to update multiple items in a list based upon some common characteristic or metadata criteria.
IMPORTANT NOTE: The first iterations of this function only worked with lists, not Document Libraries. As of v0.6.1, it works with Document libraries as well.
The SPUpdateMultipleListItems function works like this:
None
$().SPServices.SPUpdateMultipleListItems({
webURL: "",
listName: "",
CAMLQuery: "",
batchCmd: "Update",
valuepairs: [],
debug: false,
completefunc: null
});
The URL of the Web (site) which contains the list. If not specified, the current site is used. Examples would be: "/"
, "/Accounting"
, "/Departments/HR"
, etc. Note: It's always best to use relative URLs.
The name or GUID of the list. If you choose to use the GUID, it should look like: "{E73FEA09-CF8F-4B30-88C7-6FA996EE1706}"
. Note also that if you use the GUID, you do not need to specify the webURL if the list is in another site.
The CAMLQuery option allows you to specify the filter on the list. CAMLQuery here should contain valid CAML such as:
CAMLQuery: "<Query><Where><Eq><FieldRef Name='Status'/><Value Type='Text'>Active</Value></Eq></Where></Query>"
The batchCmd option specifies what the action should be. The choices are "Update"
or "Delete"
. "Update"
is the default.
If specified, the completefunc will be called each time there is a change to parentColumn. Potential uses for the completefunc: consistent default formatting overrides, additional lookup customizations, image manipulations, etc. You can pass your completefunc in either of these two ways:
completefunc: function() {
...do something...
},
or
completefunc: doSomething, // Where doSomething is the name of your function
Setting debug: true
indicates that you would like to receive messages if anything obvious is wrong with the function call, like using a column name which doesn't exist. I call this debug mode.
NOTE: Debug mode is not implemented in the initial release of SPUpdateMultipleListItems in v0.5.8.
$().SPServices.SPUpdateMultipleListItems({
listName: "States",
CAMLQuery: "<Query><Where><Eq><FieldRef Name='Status'/><Value Type='Text'>Active</Value></Eq></Where></Query>",
valuepairs: [["Status", "Inactive"]]
});
This call to SPUpdateMultipleListItems will update all of the items in the States list which have their Status = "Active", setting their Status = "Inactive".
$().SPServices.SPUpdateMultipleListItems({
listName: "States",
CAMLQuery: "<Query><Where><Eq><FieldRef Name='Status'/><Value Type='Text'>Inactive</Value></Eq></Where></Query>",
batchCmd: "Delete"
});
This call to SPUpdateMultipleListItems will delete all of the items in the States list which have their Status = "Inactive".

I think I was just made aware of the extension Live Share in VSCode which allows collaboration
now we can have remote Lean hackathons!
Unfortunately it doesn't actually work. The remote person just gets random squiggles, because Lean is not actually running on their end.
Perhaps it is possible to modify the VS Code extension so that the output from the Lean server on the host's computer is actually propagated back to the client's.
(Similar with the LaTeX plugin. The client can't compile or even view the latest PDF from the host's end.)
@Scott Morrison I thought you and I got it working at some point?
It works better if you disable your own checking (i.e. on the bottom navigational bar (coloured blue by default) click (checking visible files)
and select nothing
), since the host's Lean is still fully functional and you can see the error transmitted from the host; however sometimes the errors go out of sync and it seems that the only way to resolve this issue is to quit and rejoin the session.

| cache_rds {xfun} | R Documentation |
Save the value of an expression to a cache file (of the RDS format). Next time the value is loaded from the file if it exists.
cache_rds( expr = { }, rerun = FALSE, file = "cache.rds", dir = "cache/", hash = NULL, clean = getOption("xfun.cache_rds.clean", TRUE), ... )
expr |
An R expression. |
rerun |
Whether to delete the RDS file, rerun the expression, and save the result again (i.e., invalidate the cache if it exists). |
file |
The base (see Details) cache filename under the directory
specified by the |
dir |
The path of the RDS file is partially determined by
|
hash |
A |
clean |
Whether to clean up the old cache files automatically when
|
... |
Other arguments to be passed to |
Note that the file
argument does not provide the full cache filename.
The actual name of the cache file is of the form ‘BASENAME_HASH.rds’,
where ‘BASENAME’ is the base name provided via the ‘file’ argument
(e.g., if file = 'foo.rds'
, BASENAME
would be ‘foo’), and
‘HASH’ is the MD5 hash (also called the ‘checksum’) calculated
from the R code provided to the expr
argument and the value of the
hash
argument, which means when the code or the hash
argument
changes, the ‘HASH’ string may also change, and the old cache will be
invalidated (if it exists). If you want to find the cache file, look for
‘.rds’ files that contain 32 hexadecimal digits (consisting of 0-9 and
a-z) at the end of the filename.
The possible ways to invalidate the cache are: 1) change the code in
expr
argument; 2) delete the cache file manually or automatically
through the argument rerun = TRUE
; and 3) change the value of the
hash
argument. The first two ways should be obvious. For the third
way, it makes it possible to automatically invalidate the cache based on
changes in certain R objects. For example, when you run cache_rds({ x +
y })
, you may want to invalidate the cache to rerun { x + y }
when
the value of x
or y
has been changed, and you can tell
cache_rds()
to do so by cache_rds({ x + y }, hash = list(x,
y))
. The value of the argument hash
is expected to be a list, but it
can also take a special value, "auto"
, which means
cache_rds(expr)
will try to automatically figure out the global
variables in expr
, return a list of their values, and use this list as
the actual value of hash
. This behavior is most likely to be what you
really want: if the code in expr
uses an external global variable, you
may want to invalidate the cache if the value of the global variable has
changed. Here a “global variable” means a variable not created locally
in expr
, e.g., for cache_rds({ x <- 1; x + y })
, x
is a
local variable, and y
is (most likely to be) a global variable, so
changes in y
should invalidate the cache. However, you know your own
code the best. If you want to be completely sure when to invalidate the
cache, you can always provide a list of objects explicitly rather than
relying on hash = "auto"
.
By default (the argument clean = TRUE
), old cache files will be
automatically cleaned up. Sometimes you may want to use clean = FALSE
(set the R global option options(xfun.cache_rds.clean = FALSE)
if you
want FALSE
to be the default). For example, you may not have decided
which version of code to use, and you can keep the cache of both versions
with clean = FALSE
, so when you switch between the two versions of
code, it will still be fast to run the code.
If the cache file does not exist, run the expression and save the result to the file, otherwise read the cache file and return the value.
Changes in the code in the expr
argument do not necessarily
always invalidate the cache, if the changed code is parsed
to
the same expression as the previous version of the code. For example, if
you have run cache_rds({Sys.sleep(5);1+1})
before, running
cache_rds({ Sys.sleep( 5 ) ; 1 + 1 })
will use the cache, because
the two expressions are essentially the same (they only differ in white
spaces). Usually you can add/delete white spaces or comments to your code
in expr
without invalidating the cache. See the package vignette
vignette('xfun', package = 'xfun')
for more examples.
When this function is called in a code chunk of a knitr document, you may not want to provide the filename or directory of the cache file, because they have reasonable defaults.
Side-effects (such as plots or printed output) will not be cached. The
cache only stores the last value of the expression in expr
.
f = tempfile() # the cache file compute = function(...) { res = xfun::cache_rds({ Sys.sleep(1) 1:10 }, file = f, dir = "", ...) res } compute() # takes one second compute() # returns 1:10 immediately compute() # fast again compute(rerun = TRUE) # one second to rerun compute() file.remove(f)

Yerevan I - Night Train
My journey to Armenia started with a trip to the central train station in Tbilisi. For foreigners, that’s apparently the only place where they can buy train tickets. So I took a sweaty subway to the central station and walked up to the counter. The lady there looked as if she had smiled maybe once in her life and found the experience wanting.
Luckily, she also understood some English so I approached the topic with all the minimalist eloquence developed during this trip:
Me: Ticket. Yerevan. Tomorrow? Bileti?
Her: Yes.
Me: What time?
Her: No.
Me: Time? *pointing at the clock*
Her: *writes 10pm on a sheet of paper*
Me: How much money?
Her: No.
Me: *holding up my wallet*
Her: *writes down 80 GEL and 100 GEL*
Me: Class one and class two?
Her: *nods*
Me: Yerevan. Tomorrow. Class one bileti.
Her: Passport?
Me: No.
I had left my passport in the hostel. Showing her a scan of my passport on my phone also elicited several headshakes.
Me: Reserve bileti?
Her: No.
Me: Money now. Reserve Bileti. Passport two hours?
Her: No.
Patiently massaging my temples I said a cheerful goodbye (and mumbled a few other things not fit for publication) and walked back to the subway to get my passport.
I blame myself. But I also kind of blame the Soviets.
By the way, after this trip I probably won’t be able to form coherent sentences anymore…
In the evening of the following day, I arrived at the central station with plenty of time to spare. I was told to await the train on platform 3 and went to sit outside and enjoy the evening.
About ten minutes before the planned departure there was no train in sight. Getting nervous, I started paying attention to the announcements on the platform. Most of it was unintelligible, but I thought I heard something like “Yerevan” and “four” in the same sentence. The only other person on platform 3 was a girl with a backpack. Of course she was a German on her way to Yerevan. Since neither of us was sure about the announcements we walked back to the service desk and were, once again, told to go to platform 3. We did, only to hear the same announcement as before. So we went back to the desk to really, really make sure. No, no, platform 3 was right. In the end, we ignored them and went to platform 4, where we just barely managed to jump on before the train pulled out of the station. We parted ways, since she had been frugal and gotten the 2nd-class ticket while I had splurged on the fancy 1st-class luxury sleeper cabin.
As we drove out of Tbilisi, a thunderstorm started and lightning flashed over the dark villages and Georgia’s beautiful rolling countryside.
As I was standing outside my cabin and taking in the view, I was offered a bottle of wine by the guy from the cabin next door. He turned out to be a German photographer from my hometown, who was travelling around the Caucasus for both work and pleasure. Since we got along quite well, we decided to head to the dining car and have a few beers. A few beers turned into many beers, until suddenly we were ushered out of the dining car. It turned out that we had stopped at the border. Consequently, all toilets had been locked. So had the train doors. For some of us, this caused some distress. A few beers, some wine, some water even. It was only after having our passports checked at the Georgian side of the border that we were allowed to leave the train at the Armenian border station and use the facilities there. In return, the Armenians took close to 90 minutes to check our passports. Eventually we started moving again. I fell on my bunk and into restless, dreamless sleep as we rolled into Armenia.
Until next time,
Arne

Sometime we need to update timestamp-column when row is changed. there are a lot of solution that you do. figure out about it...
Like this.
one way to just do updating sql or other way to use trigger.
I am going to tell you about trigger is good sometime is not.
I got following post from stackoverflow, some people uploaded
In Mysql, do like the following thing.
create table ab ( id int, changeTimestamp timestamp NOT NULL default CURRENT_TIMESTAMP on update CURRENT_TIMESTAMP );
but In PostgreSQL is not worked. so there is other solution i got from stackoverflow. you can refer the following thing.
comment
Create a function that updates the changetimestamp column of a table like so:
CREATE OR REPLACE FUNCTION update_changetimestamp_column() RETURNS TRIGGER AS $$ BEGIN NEW.changetimestamp = now(); RETURN NEW; END; $$ language 'plpgsql';
Create a trigger on the table that calls the update_changetimestamp_column() function whenever an update occurs like so:
CREATE TRIGGER update_ab_changetimestamp BEFORE UPDATE ON ab FOR EACH ROW EXECUTE PROCEDURE update_changetimestamp_column();
That's the solution i got. if you need more information, just refer the top of url. thanks for reading.

Just came out of surgery and felt pretty awful so I asked for some pain relief. The nurse shot my thigh with 10mg morphine. No effects were noticed for probably 30 minutes, when I started to calm down and relax a little. They took me back to my room, where I started to feel reasonable and decided I needed a piss so I could concentrate on the drugs effects. Having urinated with difficulty I settled back into bed. I felt like closing my eyes but not sleepy. When I did close my eyes I found extremely lucid images of street and rustling leaves. The images where somewhat grey although some low intensity redness was present. They where really dreams I suppose for I was walking those streets etc.
Once again the rustling of leaves was extremely vivid, I have no idea why this would be so. When my eyes were open, the items in the room swam up and down leaving mild tracers. At the peak as I opened my eyes the ceiling became a golden honeycomb structure. All in all the primary plus for this drug is that it completely relieved the discomfort I felt. I even refused the further painkillers they later offered. It was no doubt context, but I felt no euphoria, just releif. I was even a little freaked out by the hallucinations. I had wanted to experience the fentanyl given during anaesthesia but I'd fallen unconcious too soon. This may have been more enjoyable.

VISION
We believe in philosophy of UBUNTU, i am because we are , our vision is to make students familiar with :
Algorithms and how they can use them in real world problems along with encouraging them to participate in various competitive programming events such as acm-icpc , codechef , codeforce ,hackerearth competitions just to name a few.
Getting started with working on open-source, collabarating and building together, learning from mentors, contributing to community
and encouraging them to praticipate in remote internship programs .Sharing and discussing about Research and Development, Future of computer science .
Organizational Structure
Coordinators:
The club is currently headed by 4 Coordinators, who are Pre-Final year Undergraduate students. The coordinators serve a tenure of 1 year and are responsible for the conduction of all the activities as well as managing the finances. They often take lectures for the benefit of the students.
Secretaries:
20-25 Secretaries work with the Coordinators to assist in the working of the club. They are responsible for the publicity of the events, contributing the questions in . Usually, the secretaries are Undergraduate Sophomores.
PClub includes, and collaborates with various other programming groups around campus, such as “Curiosity Club”, “jec-racers” , “go-jec”, “Google Developers Group” (ACA), “Association for Computing Activites” (ACA).
Activities
Lectures:
The Programming Club holds regular lectures across diverse fields such as algorithms, web development, and app development. The lectures often involve live demos on programming and development.
Applications:
The club often develops and deploys applications for the campus junta. For instance, Puppy Love is a couple matching platform used during the Valentines week.
Summer Camp:
The Club organizes a summer camp every year during the academic summer break. This 40 day long camp offers multiple projects to students who have finished their freshman year, and wish to learn more about Programming through practical projects. These projects are mentored by senior students, and are overseen by the Coordinators. In addition to this, the summer camp also involves various lectures and internal contests for the learning and benefit of the people on campus during the summers. Projects done in the past have been very successful and have received much attention.
Contests:
The club, apart from learning opportunities, also conducts various competitions for the students, to provide them a platform to test their knowledge in a competitive environment. The various contests are described in a separate section. Contests
Freshers’ Programming Contest:
This contest is organized right in the beginning of the first semester, soon after the first introductory lecture and introductory workshop. It consists of various basic algorithmic and programming tasks, very similar in pattern to online contests, but of a much simpler level. This helps recognize people who are already skilled at programming, to ensure that they get the requisite attention. But not just this, this also helps people new to programming to begin foraying into competitive programming.
HackaStart:
This fresher-only contest is conducted as a part of Helix, the inter-hall JEC contest. It involves two stages, beginning with a stage having maths and logic questions; followed by the final stage. The final stage involves programming in an unknown esoteric programming language, which is provided (with the compiler and documentation) at the beginning of the contest. The students have to write certain programs in this new language within the time constraints.
Codeconclave :
This a contest on competitive programming, again a part of Helix, and involves residents of halls collaborating to write solutions to algorithmic problems while competing with the other halls.
Weekend Programming Contests:
The club organizes a couple of Weekend Programming Contests every year for jecians, with prizes for top performers to encourage participation. The contests are algorithmic in nature.
Equipment
The Programming club has, in its possession, a wide array of gadgets and tools which are used for conducting projects. Some of them are: Microsoft Kinect, Raspberry Pi 2, Raspberry Pi 3, LeapMotion device, Google Nexus 5, Google Cardboard etc.

Rufus du Sol, Flume lead Australian Grammy Award nominations
by Peter MitchellAustralian alternative dance group Rufus Du Sol and DJ Flume will go head-to-head at this year's Grammy Awards.
The Australians were nominated on Wednesday in the Best Dance/Electronic Album category, with Rufus Du Sol getting the nod for Solace and Flume for Hi This is Flume.
Sydney's Rufus Du Sol were also nominated in the Best Dance Recording category for Underwater.
Australia's other nominees included For King & Country who also received two nods.
They were nominated for Best Contemporary Christian Music Performance or Song for God Only Knows, their collaboration with Dolly Parton, and Best Contemporary Christian Music Album for Burn the Ships.
Baz Luhrmann also received a nod for Moulin Rouge! The Musical for Best Musical Theatre Album.
Overall, US rapper Lizzo led the Grammy nominations with eight nods, followed by 17-year-old alt-pop sensation Billie Eilish and country rapper Lil Nas X with six apiece.
Lizzo, Eilish and Lil Nas X scored nods for the top awards - album and record of the year, as well as best new artist.
The trio will compete in the album of the year race with Bon Iver, Lana del Rey, Ariana Grande, Vampire Weekend and H.E.R.
The three artists have enjoyed a break-out year with hits like Truth Hurts (Lizzo), Bad Guy (Eilish) and Old Town Road (Lil Nas X and Billy Ray Cyrus).
Their domination of the nominations injected new life into the Grammy Awards, overshadowing established artists including Taylor Swift, who was omitted from the album and record of the year categories.
Swift, whose new album Lover is one of the year's biggest sellers, was nominated for song of the year for the title track and for best pop vocal album and pop solo performance.
The Grammy Awards, chosen by members of the Recording Academy, are the highest honors in the music industry.
The upcoming Grammy Awards marks the inaugural ceremony under the leadership of Deborah Dugan, the first female president in the history of the Recording Academy.
In August, she took the reins from Neil Portnow, who ran the organisation for 17 years; in his final year, he sparked controversy by suggesting that women needed to "step up" to win more awards after only one solo female artist was given a trophy during the 2018 Grammys telecast.

Please refer to TEP 115 for more information about this component and its
intended use.
This is the internal implementation of the standard power management
policy for managing the power states of non-virtualized devices.
Non-virtualized devices are shared using a parameterized Resource
interface, and are powered down according to some policy whenever there
are no more pending requests to that Resource. The policy implemented
by this component is to power down a device as soon as it becomes free.
Such a policy is useful whenever a device has a negligible wake-up
latency. There is no cost associated with waiting for the device to
power up, so it can be powered on and off as often as possible.
Powerdown of the device is done through the AsyncStdControl
interface, so this component can only be used with those devices that
provide that interface.
For devices providing either the StdControl
or
SplitControl
interfaces, please use either the
StdControlPowerManagerC
component or the
SplitControlPowerManagerC
component respectively.

5 May.--I must have been asleep, for certainly if I had been fully awake I must have noticed the approach of such a remarkable place. In the gloom the courtyard looked of considerable size, and as several dark ways led from it under great round arches, it perhaps seemed bigger than it really is. I have not yet been able to see it by daylight.
When the caleche stopped, the driver jumped down and held out his hand to assist me to alight. Again I could not but notice his prodigious strength. His hand actually seemed like a steel vice that could have crushed mine if he had chosen. Then he took my traps, and placed them on the ground beside me as I stood close to a great door, old and studded with large iron nails, and set in a projecting doorway of massive stone. I could see even in the dim light that the stone was massively carved, but that the carving had been much worn by time and weather. As I stood, the driver jumped again into his seat and shook the reins. The horses started forward, and trap and all disappeared down one of the dark openings.
I stood in silence where I was, for I did not know what to do. Of bell or knocker there was no sign. Through these frowning walls and dark window openings it was not likely that my voice could penetrate. The time I waited seemed endless, and I felt doubts and fears crowding upon me. What sort of place had I come to, and among what kind of people? What sort of grim adventure was it on which I had embarked? Was this a customary incident in the life of a solicitor's clerk sent out to explain the purchase of a London estate to a foreigner? Solicitor's clerk! Mina would not like that. Solicitor, for just before leaving London I got word that my examination was successful, and I am now a full-blown solicitor! I began to rub my eyes and pinch myself to see if I were awake. It all seemed like a horrible nightmare to me, and I expected that I should suddenly awake, and find myself at home, with the dawn struggling in through the windows, as I had now and again felt in the morning after a day of overwork. But my flesh answered the pinching test, and my eyes were not to be deceived. I was indeed awake and among the Carpathians. All I could do now was to be patient, and to wait the coming of morning.
Just as I had come to this conclusion I heard a heavy step approaching behind the great door, and saw through the chinks the gleam of a coming light. Then there was the sound of rattling chains and the clanking of massive bolts drawn back. A key was turned with the loud grating noise of long disuse, and the great door swung back.
Within, stood a tall old man, clean shaven save for a long white moustache, and clad in black from head to foot, without a single speck of colour about him anywhere. He held in his hand an antique silver lamp, in which the flame burned without a chimney or globe of any kind, throwing long quivering shadows as it flickered in the draught of the open door. The old man motioned me in with his right hand with a courtly gesture, saying in excellent English, but with a strange intonation.
"Welcome to my house! Enter freely and of your own free will!" He made no motion of stepping to meet me, but stood like a statue, as though his gesture of welcome had fixed him into stone. The instant, however, that I had stepped over the threshold, he moved impulsively forward, and holding out his hand grasped mine with a strength which made me wince, an effect which was not lessened by the fact that it seemed cold as ice, more like the hand of a dead than a living man. Again he said,
"Welcome to my house! Enter freely. Go safely, and leave something of the happiness you bring!" The strength of the handshake was so much akin to that which I had noticed in the driver, whose face I had not seen, that for a moment I doubted if it were not the same person to whom I was speaking. So to make sure, I said interrogatively, "Count Dracula?"
He bowed in a courtly way as he replied, "I am Dracula, and I bid you welcome, Mr. Harker, to my house. Come in, the night air is chill, and you must need to eat and rest." As he was speaking, he put the lamp on a bracket on the wall, and stepping out, took my luggage. He had carried it in before I could forestall him. I protested, but he insisted.
"Nay, sir, you are my guest. It is late, and my people are not available. Let me see to your comfort myself." He insisted on carrying my traps along the passage, and then up a great winding stair, and along another great passage, on whose stone floor our steps rang heavily. At the end of this he threw open a heavy door, and I rejoiced to see within a well-lit room in which a table was spread for supper, and on whose mighty hearth a great fire of logs, freshly replenished, flamed and flared.
The Count halted, putting down my bags, closed the door, and crossing the room, opened another door, which led into a small octagonal room lit by a single lamp, and seemingly without a window of any sort. Passing through this, he opened another door, and motioned me to enter. It was a welcome sight. For here was a great bedroom well lighted and warmed with another log fire, also added to but lately, for the top logs were fresh, which sent a hollow roar up the wide chimney. The Count himself left my luggage inside and withdrew, saying, before he closed the door.
"You will need, after your journey, to refresh yourself by making your toilet. I trust you will find all you wish. When you are ready, come into the other room, where you will find your supper prepared."
The light and warmth and the Count's courteous welcome seemed to have dissipated all my doubts and fears. Having then reached my normal state, I discovered that I was half famished with hunger. So making a hasty toilet, I went into the other room.
I found supper already laid out. My host, who stood on one side of the great fireplace, leaning against the stonework, made a graceful wave of his hand to the table, and said,
"I pray you, be seated and sup how you please. You will I trust, excuse me that I do not join you, but I have dined already, and I do not sup."
I handed to him the sealed letter which Mr. Hawkins had entrusted to me. He opened it and read it gravely. Then, with a charming smile, he handed it to me to read. One passage of it, at least, gave me a thrill of pleasure.
"I must regret that an attack of gout, from which malady I am a constant sufferer, forbids absolutely any travelling on my part for some time to come. But I am happy to say I can send a sufficient substitute, one in whom I have every possible confidence. He is a young man, full of energy and talent in his own way, and of a very faithful disposition. He is discreet and silent, and has grown into manhood in my service. He shall be ready to attend on you when you will during his stay, and shall take your instructions in all matters."
The count himself came forward and took off the cover of a dish, and I fell to at once on an excellent roast chicken. This, with some cheese and a salad and a bottle of old tokay, of which I had two glasses, was my supper. During the time I was eating it the Count asked me many questions as to my journey, and I told him by degrees all I had experienced.
 I had now an opportunity of observing him, and found him of a very marked physiognomy.
His face was a strong, a very strong, aquiline, with high bridge of the thin nose and peculiarly arched nostrils, with lofty domed forehead, and hair growing scantily round the temples but profusely elsewhere. His eyebrows were very massive, almost meeting over the nose, and with bushy hair that seemed to curl in its own profusion. The mouth, so far as I could see it under the heavy moustache, was fixed and rather cruel-looking, with peculiarly sharp white teeth. These protruded over the lips, whose remarkable ruddiness showed astonishing vitality in a man of his years. For the rest, his ears were pale, and at the tops extremely pointed. The chin was broad and strong, and the cheeks firm though thin. The general effect was one of extraordinary pallor.
Hitherto I had noticed the backs of his hands as they lay on his knees in the firelight, and they had seemed rather white and fine. But seeing them now close to me, I could not but notice that they were rather coarse, broad, with squat fingers. Strange to say, there were hairs in the centre of the palm. The nails were long and fine, and cut to a sharp point. As the Count leaned over me and his hands touched me, I could not repress a shudder. It may have been that his breath was rank, but a horrible feeling of nausea came over me, which, do what I would, I could not conceal.
The Count, evidently noticing it, drew back. And with a grim sort of smile, which showed more than he had yet done his protruberant teeth, sat himself down again on his own side of the fireplace. We were both silent for a while, and as I looked towards the window I saw the first dim streak of the coming dawn. There seemed a strange stillness over everything. But as I listened, I heard as if from down below in the valley the howling of many wolves. The Count's eyes gleamed, and he said.
"Listen to them, the children of the night. What music they make!" Seeing, I suppose, some expression in my face strange to him, he added, "Ah, sir, you dwellers in the city cannot enter into the feelings of the hunter." Then he rose and said.
"But you must be tired. Your bedroom is all ready, and tomorrow you shall sleep as late as you will. I have to be away till the afternoon, so sleep well and dream well!" With a courteous bow, he opened for me himself the door to the octagonal room, and I entered my bedroom.
I am all in a sea of wonders. I doubt. I fear. I think strange things, which I dare not confess to my own soul. God keep me, if only for the sake of those dear to me!
7 May.--It is again early morning, but I have rested and enjoyed the last twenty-four hours. I slept till late in the day, and awoke of my own accord. When I had dressed myself I went into the room where we had supped, and found a cold breakfast laid out, with coffee kept hot by the pot being placed on the hearth. There was a card on the table, on which was written--"I have to be absent for a while. Do not wait for me. D." I set to and enjoyed a hearty meal. When I had done, I looked for a bell, so that I might let the servants know I had finished, but I could not find one. There are certainly odd deficiencies in the house, considering the extraordinary evidences of wealth which are round me. The table service is of gold, and so beautifully wrought that it must be of immense value. The curtains and upholstery of the chairs and sofas and the hangings of my bed are of the costliest and most beautiful fabrics, and must have been of fabulous value when they were made, for they are centuries old, though in excellent order. I saw something like them in Hampton Court, but they were worn and frayed and moth-eaten. But still in none of the rooms is there a mirror.  I have not yet seen a servant anywhere, or heard a sound near the castle except the howling of wolves. Some time after I had finished my meal, I do not know whether to call it breakfast or dinner, for it was between five and six o'clock when I had it, I looked about for something to read, for I did not like to go about the castle until I had asked the Count's permission. There was absolutely nothing in the room, book, newspaper, or even writing materials, so I opened another door in the room and found a sort of library. The door opposite mine I tried, but found locked.
In the library I found, to my great delight, a vast number of English books, whole shelves full of them, and bound volumes of magazines and newspapers. A table in the centre was littered with English magazines and newspapers, though none of them were of very recent date. The books were of the most varied kind, history, geography, politics, political economy, botany, geology, law, all relating to England and English life and customs and manners. There were even such books of reference as the London Directory, the "Red" and "Blue" books, Whitaker's Almanac, the Army and Navy Lists, and it somehow gladdened my heart to see it, the Law List.
Whilst I was looking at the books, the door opened, and the Count entered. He saluted me in a hearty way, and hoped that I had had a good night's rest. Then he went on.
"I am glad you found your way in here, for I am sure there is much that will interest you. These companions," and he laid his hand on some of the books, "have been good friends to me, and for some years past, ever since I had the idea of going to London, have given me many, many hours of pleasure. Through them I have come to know your great England, and to know her is to love her. I long to go through the crowded streets of your mighty London, to be in the midst of the whirl and rush of humanity, to share its life, its change, its death, and all that makes it what it is. But alas! As yet I only know your tongue through books. To you, my friend, I look that I know it to speak."
"But, Count," I said, "You know and speak English thoroughly!" He bowed gravely.
"I thank you, my friend, for your all too-flattering estimate, but yet I fear that I am but a little way on the road I would travel. True, I know the grammar and the words, but yet I know not how to speak them."
"Indeed," I said, "You speak excellently."
"Not so," he answered. "Well, I know that, did I move and speak in your London, none there are who would not know me for a stranger. That is not enough for me. Here I am noble. I am a Boyar. The common people know me, and I am master. But a stranger in a strange land, he is no one. Men know him not, and to know not is to care not for. I am content if I am like the rest, so that no man stops if he sees me, or pauses in his speaking if he hears my words, 'Ha, ha! A stranger!' I have been so long master that I would be master still, or at least that none other should be master of me. You come to me not alone as agent of my friend Peter Hawkins, of Exeter, to tell me all about my new estate in London. You shall, I trust, rest here with me a while, so that by our talking I may learn the English intonation. And I would that you tell me when I make error, even of the smallest, in my speaking. I am sorry that I had to be away so long today, but you will, I know forgive one who has so many important affairs in hand."
Of course I said all I could about being willing, and asked if I might come into that room when I chose. He answered, "Yes, certainly," and added.
"You may go anywhere you wish in the castle, except where the doors are locked, where of course you will not wish to go. There is reason that all things are as they are, and did you see with my eyes and know with my knowledge, you would perhaps better understand." I said I was sure of this, and then he went on.
"We are in Transylvania, and Transylvania is not England. Our ways are not your ways, and there shall be to you many strange things. Nay, from what you have told me of your experiences already, you know something of what strange things there may be."
This led to much conversation, and as it was evident that he wanted to talk, if only for talking's sake, I asked him many questions regarding things that had already happened to me or come within my notice. Sometimes he sheered off the subject, or turned the conversation by pretending not to understand, but generally he answered all I asked most frankly. Then as time went on, and I had got somewhat bolder, I asked him of some of the strange things of the preceding night, as for instance, why the coachman went to the places where he had seen the blue flames. He then explained to me that it was commonly believed that on a certain night of the year, last night, in fact, when all evil spirits are supposed to have unchecked sway, a blue flame is seen over any place where treasure has been concealed.
"That treasure has been hidden," he went on, "in the region through which you came last night, there can be but little doubt. For it was the ground fought over for centuries by the Wallachian, the Saxon, and the Turk. Why, there is hardly a foot of soil in all this region that has not been enriched by the blood of men, patriots or invaders. In the old days there were stirring times, when the Austrian and the Hungarian came up in hordes, and the patriots went out to meet them, men and women, the aged and the children too, and waited their coming on the rocks above the passes, that they might sweep destruction on them with their artificial avalanches. When the invader was triumphant he found but little, for whatever there was had been sheltered in the friendly soil."
"But how," said I, "can it have remained so long undiscovered, when there is a sure index to it if men will but take the trouble to look?" The Count smiled, and as his lips ran back over his gums, the long, sharp, canine teeth showed out strangely. He answered:
"Because your peasant is at heart a coward and a fool! Those flames only appear on one night, and on that night no man of this land will, if he can help it, stir without his doors. And, dear sir, even if he did he would not know what to do. Why, even the peasant that you tell me of who marked the place of the flame would not know where to look in daylight even for his own work. Even you would not, I dare be sworn, be able to find these places again?"
"There you are right," I said. "I know no more than the dead where even to look for them." Then we drifted into other matters.
"Come," he said at last, "tell me of London and of the house which you have procured for me." With an apology for my remissness, I went into my own room to get the papers from my bag. Whilst I was placing them in order I heard a rattling of china and silver in the next room, and as I passed through, noticed that the table had been cleared and the lamp lit, for it was by this time deep into the dark. The lamps were also lit in the study or library, and I found the Count lying on the sofa, reading, of all things in the world, an English Bradshaw's Guide. When I came in he cleared the books and papers from the table, and with him I went into plans and deeds and figures of all sorts. He was interested in everything, and asked me a myriad questions about the place and its surroundings. He clearly had studied beforehand all he could get on the subject of the neighbourhood, for he evidently at the end knew very much more than I did. When I remarked this, he answered.
"Well, but, my friend, is it not needful that I should? When I go there I shall be all alone, and my friend Harker Jonathan, nay, pardon me. I fall into my country's habit of putting your patronymic first, my friend Jonathan Harker will not be by my side to correct and aid me. He will be in Exeter, miles away, probably working at papers of the law with my other friend, Peter Hawkins. So!"
We went thoroughly into the business of the purchase of the estate at Purfleet. When I had told him the facts and got his signature to the necessary papers, and had written a letter with them ready to post to Mr. Hawkins, he began to ask me how I had come across so suitable a place. I read to him the notes which I had made at the time, and which I inscribe here.
"At Purfleet, on a byroad, I came across just such a place as seemed to be required, and where was displayed a dilapidated notice that the place was for sale. It was surrounded by a high wall, of ancient structure, built of heavy stones, and has not been repaired for a large number of years. The closed gates are of heavy old oak and iron, all eaten with rust.
"The estate is called Carfax, no doubt a corruption of the old Quatre Face, as the house is four sided, agreeing with the cardinal points of the compass. It contains in all some twenty acres, quite surrounded by the solid stone wall above mentioned. There are many trees on it, which make it in places gloomy, and there is a deep, dark-looking pond or small lake, evidently fed by some springs, as the water is clear and flows away in a fair-sized stream. The house is very large and of all periods back, I should say, to mediaeval times, for one part is of stone immensely thick, with only a few windows high up and heavily barred with iron. It looks like part of a keep, and is close to an old chapel or church. I could not enter it, as I had not the key of the door leading to it from the house, but I have taken with my Kodak views of it from various points. The house had been added to, but in a very straggling way, and I can only guess at the amount of ground it covers, which must be very great. There are but few houses close at hand, one being a very large house only recently added to and formed into a private lunatic asylum. It is not, however, visible from the grounds."
When I had finished, he said, "I am glad that it is old and big.  A house cannot be made habitable in a day, and after all, how few days go to make up a century. I rejoice also that there is a chapel of old times. We Transylvanian nobles love not to think that our bones may lie amongst the common dead. I seek not gaiety nor mirth, not the bright voluptuousness of much sunshine and sparkling waters which please the young and gay. I am no longer young, and my heart, through weary years of mourning over the dead, is not attuned to mirth. Moreover, the walls of my castle are broken. The shadows are many, and the wind breathes cold through the broken battlements and casements. I love the shade and the shadow, and would be alone with my thoughts when I may." Somehow his words and his look did not seem to accord, or else it was that his cast of face made his smile look malignant and saturnine.
Presently, with an excuse, he left me, asking me to pull my papers together. He was some little time away, and I began to look at some of the books around me. One was an atlas, which I found opened naturally to England, as if that map had been much used. On looking at it I found in certain places little rings marked, and on examining these I noticed that one was near London on the east side, manifestly where his new estate was situated. The other two were Exeter, and Whitby on the Yorkshire coast.
It was the better part of an hour when the Count returned. "Aha!" he said. "Still at your books? Good! But you must not work always. Come! I am informed that your supper is ready." He took my arm, and we went into the next room, where I found an excellent supper ready on the table. The Count again excused himself, as he had dined out on his being away from home. But he sat as on the previous night, and chatted whilst I ate. After supper I smoked, as on the last evening, and the Count stayed with me, chatting and asking questions on every conceivable subject, hour after hour. I felt that it was getting very late indeed, but I did not say anything, for I felt under obligation to meet my host's wishes in every way. I was not sleepy, as the long sleep yesterday had fortified me, but I could not help experiencing that chill which comes over one at the coming of the dawn, which is like, in its way, the turn of the tide. They say that people who are near death die generally at the change to dawn or at the turn of the tide. Anyone who has when tired, and tied as it were to his post, experienced this change in the atmosphere can well believe it. All at once we heard the crow of the cock coming up with preternatural shrillness through the clear morning air.
Count Dracula, jumping to his feet, said, "Why there is the morning again! How remiss I am to let you stay up so long. You must make your conversation regarding my dear new country of England less interesting, so that I may not forget how time flies by us," and with a courtly bow, he quickly left me.
I went into my room and drew the curtains, but there was little to notice. My window opened into the courtyard, all I could see was the warm grey of quickening sky. So I pulled the curtains again, and have written of this day.
8 May.--I began to fear as I wrote in this book that I was getting too diffuse. But now I am glad that I went into detail from the first, for there is something so strange about this place and all in it that I cannot but feel uneasy. I wish I were safe out of it, or that I had never come. It may be that this strange night existence is telling on me, but would that that were all! If there were any one to talk to I could bear it, but there is no one. I have only the Count to speak with, and he--I fear I am myself the only living soul within the place. Let me be prosaic so far as facts can be. It will help me to bear up, and imagination must not run riot with me. If it does I am lost. Let me say at once how I stand, or seem to.
I only slept a few hours when I went to bed, and feeling that I could not sleep any more, got up. I had hung my shaving glass by the window, and was just beginning to shave. Suddenly I felt a hand on my shoulder, and heard the Count's voice saying to me, "Good morning." I started, for it amazed me that I had not seen him, since the reflection of the glass covered the whole room behind me. In starting I had cut myself slightly, but did not notice it at the moment. Having answered the Count's salutation, I turned to the glass again to see how I had been mistaken. This time there could be no error, for the man was close to me, and I could see him over my shoulder. But there was no reflection of him in the mirror! The whole room behind me was displayed, but there was no sign of a man in it, except myself.
This was startling, and coming on the top of so many strange things, was beginning to increase that vague feeling of uneasiness which I always have when the Count is near. But at the instant I saw that the cut had bled a little, and the blood was trickling over my chin. I laid down the razor, turning as I did so half round to look for some sticking plaster. When the Count saw my face, his eyes blazed with a sort of demoniac fury, and he suddenly made a grab at my throat. I drew away and his hand touched the string of beads which held the crucifix. It made an instant change in him, for the fury passed so quickly that I could hardly believe that it was ever there.
"Take care," he said, "take care how you cut yourself. It is more dangerous that you think in this country." Then seizing the shaving glass, he went on, "And this is the wretched thing that has done the mischief. It is a foul bauble of man's vanity. Away with it!" And opening the window with one wrench of his terrible hand, he flung out the glass, which was shattered into a thousand pieces on the stones of the courtyard far below. Then he withdrew without a word. It is very annoying, for I do not see how I am to shave, unless in my watch-case or the bottom of the shaving pot, which is fortunately of metal.
When I went into the dining room, breakfast was prepared, but I could not find the Count anywhere. So I breakfasted alone. It is strange that as yet I have not seen the Count eat or drink. He must be a very peculiar man! After breakfast I did a little exploring in the castle. I went out on the stairs, and found a room looking towards the South.
The view was magnificent, and from where I stood there was every opportunity of seeing it. The castle is on the very edge of a terrific precipice. A stone falling from the window would fall a thousand feet without touching anything! As far as the eye can reach is a sea of green tree tops, with occasionally a deep rift where there is a chasm. Here and there are silver threads where the rivers wind in deep gorges through the forests.
But I am not in heart to describe beauty, for when I had seen the view I explored further. Doors, doors, doors everywhere, and all locked and bolted. In no place save from the windows in the castle walls is there an available exit. The castle is a veritable prison, and I am a prisoner!

THE JUNGLE BOOK A film review by Mark R. Leeper Copyright 1994 Mark R. Leeper
Capsule: Disney Films borrows some character names from Kipling, but not any story. Spectacular Indian locations, beautiful photography, and a powerful score are wasted on a mediocre and cliched adventure film with little respect for the Kipling it was nominally based on. Rating: low +1 (-4 to +4)
An old cartoon shows someone asking "Do you like Kipling?" and getting the response "I don't know, I never Kipled." Certainly there is not much Kipling going on in Disney's sumptuous second film nominally based on Rudyard Kipling's THE JUNGLE BOOKS. [Am I the only one who thinks the book's title was in the plural?] Indeed, while Kipling might enjoy the new film for its stupendous vision of India, with the exception of recognizing a few character names, mostly animals, he would find little in this film to remind him of his own writings either in plot or style. Besides Mowgli himself, the major characters of his Mowgli stories are all animals; in the film the animals are minor characters. The new film gives a (highly inaccurate) origin for Mowgli and then entirely skips over the period that the book covers and returns to Mowgli as an adult (now played by Jason Scott Lee). Mowgli has picked up martial arts someplace and is now ready to interact with the Man-pack. In fact when he does what we have has is much more the plotting of a Tarzan movie with the setting moved to India. But even if that is so, admittedly it is a highly watchable Tarzan movie.
In the Kipling, Mowgli is a baby who has strayed from his village and nearly killed by Shere Khan, the great tiger. The Man-cub is raised by wolves. In the new film version, Mowgli is about five years old and already has facility handling elephants when he is separated from his caravan and thought to have been killed. Why he has never returned to civilization remains unexplained since he seems to have a city with a major fort just a day or two's walk away. However, he remains in his jungle until he sees and is attracted to Catherine (Lena Headly), the beautiful daughter of the commander of the fort (Sam Neill). She is already being courted by a handsome young soldier (Cary Elwes) who is a favorite of the commander, but of course the audience knows that he is a treacherous cad and a bounder to boot. When the nasty young soldier realizes that Mowgli must know the way to a legendary lost treasure city, all the expected happens.
On top of the plotting being sophomoric, it is didactic. Kipling's animals live by the Law of the Jungle, a complex and logical code which includes rules like not to kill Man as well as rules like when it is legal to take another's prey. In this version it is changed into modernistic rules of conservation. The major rule is "do not kill what you cannot eat." And the animals enforce these rules on humans. In fact, Mowgli is first stranded in the jungle when Shere Khan attacks his caravan because the travelers had killed more animals than they could eat. (This is an heroic and selfless action for Shere Khan ... totally out of character.) The heroes of THE JUNGLE BOOK all seem to have late 20th Century American values while the villains are all politically incorrect.
Another interesting problem with the film is the placing of jungle so near the fort. (In fact, the fortress is Jodhpur's breath-taking Meherangarh Fort. Having explored the 15th Century fort myself-- perhaps the term "walled city" is more accurate--I can tell you the name Meherangarh, or "majestic," is no exaggeration. But perhaps the film makes that obvious.) Even if the fort is supposed to be just some generic fort, the architecture is Rajasthani. You will probably see that style only in dry country a very long distance from any tropical jungle such as we see in other parts of this story. The decision to film the fort over-looking Jodhpur is purely an aesthetic one. This is a very beautifully photographed film. The clarity and detail of the shots and the use of color may be the best of any film I have seen this year. Disney Studios has a reputation for making high-quality prints. The score by the underrated Basil Polidouris only adds to the lush and rich texture.
The acting, as directed by Stephen Sommers, is generally acceptable though Jason Scott Lee is an odd casting choice for Mowgli. He does not look so much Indian as Oriental. Cary Elwes makes a reasonable villain who snidely personifies all that was wrong with the British Raj. Unfortunately, some of the worst acting comes from the animals who just followed direction without worrying about their careers--more is the pity. The apes in particular behave like fugitives from the Cheetah School of Bad Animal Acting. And I wonder what an orangutan is doing in the jungles of India. Rudyard Kipling treated the animals as characters but in this film the apes are sort of a Greek chorus and the rest are little more than additional fists for Mowgli to use against his enemies.
Taken as a Tarzan film or a sequel to the Kipling story, this is a watchable children's film. But putting Kipling's name over the title is gross mis-representation. The pity is that such care was taken with the visual aspects of a film so betrayed by the scripting. Parts of this film are terrific, parts are just awful. On balance this one gets a low +1 on the -4 to +4 scale.
