3.13. Code Tuning and Empirical Analysis (WORK IN PROGRESS)¶
3.13.1. Code Tuning and Empirical Analysis¶
In practice, there is not such a big difference in running time between an algorithm with growth rate \(\Theta(n)\) and another with growth rate \(\Theta(n \log n)\). There is, however, an enormous difference in running time between algorithms with growth rates of \(\Theta(n \log n)\) and \(\Theta(n^2)\). As you shall see during the course of your study of common data structures and algorithms, there are many problems whose obvious solution requires \(\Theta(n^2)\) time, but that also have a solution requiring \(\Theta(n \log n)\) time. Examples include sorting and searching, two of the most important computer problems.
While not nearly so important as changing an algorithm to reduce its growth rate, “code tuning” can also lead to dramatic improvements in running time. Code tuning is the art of hand-optimizing a program to run faster or require less storage. For many programs, code tuning can reduce running time or cut the storage requirements by a factor of two or more. Even speedups by a factor of five to ten are not uncommon. Occasionally, you can get an even bigger speedup by converting from a symbolic representation of the data to a numeric coding scheme on which you can do direct computation.

Give an example of this type of representational change.
Here are some suggestions for ways to speed up your programs by code tuning. The most important thing to realize is that most statements in a program do not have much effect on the running time of that program. There are normally just a few key subroutines, possibly even key lines of code within the key subroutines, that account for most of the running time. There is little point to cutting in half the running time of a subroutine that accounts for only 1% of the total running time. Focus your attention on those parts of the program that have the most impact.
When tuning code, it is important to gather good timing statistics. Many compilers and operating systems include profilers and other special tools to help gather information on both time and space use. These are invaluable when trying to make a program more efficient, because they can tell you where to invest your effort.
A lot of code tuning is based on the principle of avoiding work rather than speeding up work. A common situation occurs when we can test for a condition that lets us skip some work. However, such a test is never completely free. Care must be taken that the cost of the test does not exceed the amount of work saved. While one test might be cheaper than the work potentially saved, the test must always be made and the work can be avoided only some fraction of the time.
Example 3.14.1
A common operation in computer graphics applications is to find which among a set of complex objects contains a given point in space. Many useful data structures and algorithms have been developed to deal with variations of this problem. Most such implementations involve the following tuning step. Directly testing whether a given complex object contains the point in question is relatively expensive. Instead, we can screen for whether the point is contained within a bounding box for the object. The bounding box is simply the smallest rectangle (usually defined to have sides perpendicular to the \(x\) and \(y\) axes) that contains the object. If the point is not in the bounding box, then it cannot be in the object. If the point is in the bounding box, only then would we conduct the full comparison of the object versus the point. Note that if the point is outside the bounding box, we saved time because the bounding box test is cheaper than the comparison of the full object versus the point. But if the point is inside the bounding box, then that test is redundant because we still have to compare the point against the object. Typically the amount of work avoided by making this test is greater than the cost of making the test on every object.
Be careful not to use tricks that make the program unreadable. Most code tuning is simply cleaning up a carelessly written program, not taking a clear program and adding tricks. In particular, you should develop an appreciation for the capabilities of modern compilers to make extremely good optimizations of expressions. “Optimization of expressions” here means a rearrangement of arithmetic or logical expressions to run more efficiently. Be careful not to damage the compiler’s ability to do such optimizations for you in an effort to optimize the expression yourself. Always check that your “optimizations” really do improve the program by running the program before and after the change on a suitable benchmark set of input. Many times I have been wrong about the positive effects of code tuning in my own programs. Most often I am wrong when I try to optimize an expression. It is hard to do better than the compiler.
The greatest time and space improvements come from a better data structure or algorithm. The most important rule of code tuning is:
First tune the algorithm, then tune the code.
<IP_ADDRESS>. Empirical Analysis¶
Asymptotic algorithm analysis is an analytic tool, whereby we model the key aspects of an algorithm to determine the growth rate of the algorithm as the input size grows. It has proved hugely practical, guiding developers to use more efficient algorithms. But it is really an estimation technique, and it has its limitations. These include the effects at small problem size, determining the finer distinctions between algorithms with the same growth rate, and the inherent difficulty of doing mathematical modeling for more complex problems.
An alternative to analytical approaches are empirical ones. The most obvious empirical approach is simply to run two competitors and see which performs better. In this way we might overcome the deficiencies of analytical approaches.
Be warned that comparative timing of programs is a difficult business, often subject to experimental errors arising from uncontrolled factors (system load, the language or compiler used, etc.). The most important concern is that you might be biased in favor of one of the programs. If you are biased, this is certain to be reflected in the timings. One look at competing software or hardware vendors’ advertisements should convince you of this. The most common pitfall when writing two programs to compare their performance is that one receives more code-tuning effort than the other, since code tuning can often reduce running time by a factor of five to ten. If the running times for two programs differ by a constant factor regardless of input size (i.e., their growth rates are the same), then differences in code tuning might account for any difference in running time. Be suspicious of empirical comparisons in this situation.
Another approach to analytical analysis is simulation. The idea of simulation is to model the problem with a computer program and then run it to get a result. In the context of algorithm analysis, simulation is distinct from empirical comparison of two competitors because the purpose of the simulation is to perform analysis that might otherwise be too difficult. A good example of this appears in the following figure.
This figure shows the cost for inserting or deleting a record from a hash table under two different assumptions for the policy used to find a free slot in the table. The \(y\) axes is the cost in number of hash table slots evaluated, and the \(x\) axes is the percentage of slots in the table that are full. The mathematical equations for these curves can be determined, but this is not so easy. A reasonable alternative is to write simple variations on hashing. By timing the cost of the program for various loading conditions, it is not difficult to construct a plot similar to this one. The purpose of this analysis was not to determine which approach to hashing is most efficient, so we are not doing empirical comparison of hashing alternatives. Instead, the purpose was to analyze the proper loading factor that would be used in an efficient hashing system to balance time cost versus hash table size (space cost).


‘Right across the board’ - Boss explains why this Aston Villa star isn't playing
Latest Aston Villa news includes update on Andre Green's loan spell at Preston North End
by Shane Ireland, https://www.facebook.com/ShaneIrelandJournalistAndre Green has been told to earn a starting spot for Preston North End by proving himself in training.
Green linked up with Preston in early August on a season-long loan designed to give him regular exposure to first-team football.
But worryingly for Aston Villa, he is yet to make a single start for the Championship side having been limited to just six appearances off the bench.
Squad competition means it’s difficult for Green – who is currently sidelined with a toe problem – to force his way up the pecking order and into Alex Neil’s plans.

You can follow our Villa reporter Ashley Preece on Twitter, and his email address is<EMAIL_ADDRESS>Preston’s brilliant start to the season – they sit second behind West Brom after 16 matches – adds another layer to the challenge.
“When you are not in the team your training that week is even more important,” manager Neil told the Lancashire Evening Post.
“That is their opportunity to impress me and show everybody else why you should be playing.
"The difficulty they have got at the moment is how well the team has been playing and performing. It has been really difficult for some of the lads to get in.
“We could go right across the board with that but things do change."
He added: “Andre is in a position which a lot of the other lads who are not really featuring, are in. Who do you take out of the team to put him in?
"At the moment Andre has got a problem with his big toe. He’s got arthritis which means he’d had a few injections in it, so at the moment he’s not currently fit. However, that’s only been for the last couple of weeks.”
Green featured 22 times for Villa last season but after the permanent deals for Trezeguet, Anwar El Ghazi and Jota in the summer, Dean Smith made him available for a loan move.

An interesting mobile game
问题描述 :
XQ,one of the three Sailormoon girls,is usually playing mobile games on the class.Her favorite mobile game is called “The Princess In The Wall”.Now she give you a problem about this game.
Can you solve it?The following picture show this problem better.
This game is played on a rectangular area.This area is divided into some equal square grid..There are N rows and M columns.For each grid,there may be a colored square block or nothing.
Each grid has a number.
“0” represents this grid have nothing.
“1” represents this grid have a red square block.
“2” represents this grid have a blue square block.
“3” represents this grid have a green square block.
“4” represents this grid have a yellow square block.

“0” represents this grid have nothing.
“1” represents this grid have a red square block.
“2” represents this grid have a blue square block.
“3” represents this grid have a green square block.
“4” represents this grid have a yellow square block.
1. Each step,when you choose a grid have a colored square block, A group of this block and some connected blocks that are the same color would be removed from the board. no matter how many square blocks are in this group.
2. When a group of blocks is removed, the blocks above those removed ones fall down into the empty space. When an entire column of blocks is removed, all the columns to the right of that column shift to the left to fill the empty columns.
Now give you the number of the row and column and the data of each grid.You should calculate how many steps can make the entire rectangular area have no colored square blocks at least.
输入:
There are multiple test cases. Each case starts with two positive integer N, M,(N, M <= 6)the size of rectangular area. Then n lines follow, each contains m positive integers X.(0<= X <= 4)It means this grid have a colored square block or nothing.

Strictly Come Dancing has dropped the Lindy Hop-a-thon
It caused havoc last year
by Georgia LoganStrictly Come Dancing bosses have scrapped the Lindy Hop-a-thon from this year's show.
Producers have decided not to have a scored group dance at this stage of the competition following the problems that hit the event in 2018, a BBC insider told the Mirror Online.

Head judge Shirley Ballas read the scores out in the wrong order until Bruno Tonioli intervened, and the dance expert also mistakenly said Charles Venn's partner was Dianne Buswell, not Karen Hauer.
A show spokesperson said at the time: "Once the judges had scored the Lindy-hopathon, the marks were successfully electronically recorded on a tablet and fed to the gallery who received an accurate record of the judges marks.
"When Head Judge Shirley had to read the marks out live on air, the tablet she was reading from malfunctioned and went blank so she was unable to read out the final order.

"Bruno therefore read out the results from a back up, which is a paper template and had been filled in by the judges."
The axing of the group dance performance isn't the only change to the format this year.
The final of the show will feature just three competitors, rather than the usual four, because Paralympian Will Bayley pulled out of the competition earlier this month due to an injury and wasn't replaced.

Scotland sees coldest night of the autumn but escapes worst weather
by Shan RossTemperatures dropped to nearly minus 10C on Monday night - the coldest of the autumn so far.
According to the Met Office, the mercury fell to minus 9.9C (14.2F) in Braemar, Aberdeenshire.
Nine of the ten coldest locations overnight across the UK were north of the Border.
The coldest location in England was Redesdale Camp in Northumberland, where the temperature was recorded at minus 7.1C (19.2F).
Last night and early this morning the coldest temperatures in Scotland were predicted to be in Aberdeenshire and Grampian at around minus 4C and minus 5C, particularly on hilltops.
The Met Office said Scotland was likely to see warmer temperatures for the rest of the week and would be free of flooding which has struck parts of England. “The bulk of weather systems are affecting the south of the UK at the moment,” the Met Office said.
“There is a southerly wind bringing with it warmer air which means temperatures in Scotland will not fall too much.
“This means will be drier in the north of Scotland with temperatures not dropping to what we saw at the start of the week.
“But there will most likely be a few places where it will drop below zero.
“Through the rest this week Scotland is likely to see warmer temperatures, particularly in the east where it will be bright and clear.”
Overnight rainfall is expected in southern Scotland while the west and parts of the south will see cloud and rain.
Braemar also saw one of the first snowfalls across Scotland, along with the Glenshee ski centre. However, snow is not predicted to fall across the rest of Scotland in the near future.
Forecasters said the UK had already seen 68 per cent of its expected monthly rain.
Nottinghamshire has been the wettest county, having had 189 per cent of its average November rainfall by the 17th.
Parts of the Midlands and Yorkshire suffered days of flooding after torrential rain earlier this month, and Sheffield has already had its wettest ever autumn, with 17.4in (440.8mm) of rainfall so far this season.
The previous record of 16.7in (425.2mm) was set in 2000.
On the other hand, western and northern Scotland have had a much drier month, and Shetland had only had 17 per cent of its monthly rainfall by the same point.
Wind is due to reach 40-50mph, which is normal at this time of year.


Users trying to update to the recently released Build 1909 (aka November 2019 Update) to Windows 10 may have found that there's no update to install if they're running AVG or Avast as their antivirus tool.
Microsoft says it has found a compatibility issue between the renowned free software suites and Windows - both the aforementioned 1909 and its predecessor, 1903. It is standard practice for Microsoft to block updates until the issue is resolved.
The issues page for Windows 10 now reads: "Microsoft and Avast has identified compatibility issues with some versions of Avast Antivirus and AVG Antivirus. Any application from Avast or AVG that contains Antivirus version 19.5.4444.567 or earlier is affected".
It goes further by warning people not to be tempted to try and override the block by manually installing the update. Surely, that's where borkage lies.
There is a fix though - both companies have no released newer versions of their apps that don't have the compatibility issue - it's just a case of updating one before the other.
Nevertheless, we find ourselves asking the same question again - exactly how was it missed in the pre-release stage? These builds have been with the Insider Programme for, literally, months.
So how was a Windows 10 build released with such a glaring compatibility issue? It's not like these are weird little minority anti-malware packages - they're two of the biggest in the world, helped in no small part because they are free to end-users.
Both AVG and Avast have released support pages - they don't tell you much that we haven't done already, but they do give step-by-step guides on manually updating your security suite to a compatible version, manually.
You may also receive an alert when you try and run the update, but that will only help you uninstall the old version - and you really don't want to be riding bareback now, do you? μ

Wolverine (birth name: James Howlett; alias: Logan and Weapon X) is a fictional character appearing in American comic books published by Marvel Comics, mostly in association with the X-Men. He is a mutant who possesses animal-keen senses, enhanced physical capabilities, a powerful regenerative ability known as a healing factor, and three retractable claws in each hand. Wolverine has been depicted variously as a member of the X-Men, Alpha Flight, and the Avengers.
Wolverine's primary mutant power is an accelerated healing process, typically referred to as his mutant healing factor, that regenerates damaged or destroyed tissues of his body far beyond that of normal humans. In addition to accelerated healing of physical traumas, Wolverine's healing factor makes him extraordinarily resistant to diseases, drugs and toxins. However, he can still suffer the immediate effects of such substances in massive quantities; he has been seen to become intoxicated after ingesting significant amounts of alcohol, and has been incapacitated on several occasions with large amounts of powerful drugs and poisons; S.H.I.E.L.D. once managed to keep Wolverine anesthetized by constantly pumping eighty milliliters of anesthetic a minute into his system.

To view pictures, plot information, synopses and cast & crew listings for a production simply click on the relevant link from our archive below.
"Angels, shadows, voices, dreams"
.
This performance installation created a new theatrical experience from the texts, objects and memories within the Fail Better archive. The audience was invited into a different kind of theatre museum.
"Zero. Zero. Zero"
.
The beginning of a major project exploring the human body in relation to scientific knowledge, Endlessness was a Pegasus 'First Stage' performance thinking through scientific method and the void.
"I love going to the theatre. As long as I've a kopeck in my pocket, you can't stop me"
.
A bold new adaptation of Gogol's absurdist masterpiece, adapted and devised by the company. The story examines the life of Axenty Ivanovich, a civil servant whose ordered existence spirals into fantasy and despair as his obsession with the enchanting daughter of his superior grows.
Meanwhile, two little dogs contemplate his fate...
"Hell is murky"
.
A new devised piece, performed by The Student Ensemble, which freely adapts Shakespeare's tragedies in a theatrical language inspired by the work of Samuel Beckett. A highly innovative staging sees disembodied heads, emerging from a cabinet of curiosities to relive their 'rooted sorrow'.
"I don't seem to be able ... to depart"
.
A rare opportunity to see a double bill of short plays by Samuel Beckett, staged together for the first time. As their stories and lives come to an end, the characters consider what has happened, how things may have been different and what remains of the past. Static bodies in concrete stage images begin two intensely focused dramas of the mind.
"Thank you for giving me this nothing"
.
Ceres' search, Jove's judgment, Dis' lust all threaten to engulf Proserpine as she struggles to compose herself. A piece for 'nine imprisoned performers' this recycling of the Persephone myth draws upon a rich research and development process across various venues.
"I like the truth as well - just for a moment"
.
Exploring the relationship between theatre, politics and poetry, as well as the distance between reality and illusion, this lost classic marks the beginning of Lorca's quest to stage 'the impossible'.
"The worst kid in the park now"
Sometimes ferocious, sometimes delicate, this is a tale of destructive love between two young delinquents. Set on a South London estate, this stunning new play is premiered by a "young, unhyped, first-rate company"
- List. Fail Better's devised show Echo and Narcissus received critical acclaim on the London fringe last summer.
"It burns. Meant to be. We were. Meant to be."
This powerful retelling of the Phaedra myth mixes brutality and beauty, revealing a royal family ripped apart by obsessive love. Fail Better return to The Smirnoff Underbelly following their massive success with Sarah Kane's Crave in 2002 ("a diamond of a show"

Having been cursed to eternally repeat the words of others, Echo developes an infatuation for the self-obsessed Narcissus. But when he cruelly rejects her, Narcissus himself is cursed to crave the one thing he cannot reach, his own reflection.

The search for a legendary automobile almost puts an end to both the careers and the lives of husband-and-wife
team Sam and Remi Fargo, in the thrilling new adventure from the #1 New York Times -bestselling master of adventure. In 1906, a
groundbreaking Rolls-Royce prototype known as the Gray Ghost vanishes from the streets of Manchester, England, and it is only the lucky
intervention of an American detective named Isaac Bell that prevents it from being lost forever.

3.4.0 (2015-11-16)
New features and bug fixes
- Improves performance of components, templates, computeds, and observables.
- Includes a native version of deferred updates, along with a microtask queue (ko.tasks).
- Calls a ko.onError handler, if defined, for errors from asynchronous code.
- ko.options.useOnlyNativeEvents can be set to tell Knockout to use only native (not jQuery) events.
- Includes ko.isPureComputed().
The 3.4.0 RC release notes has the full list of issues and pull requests included in this release. The final release fixes two regression bugs found in the RC:
- #1903 - New beforeRemove behavior can break retained items.
- #1905 - Endless recursion possible with ko.computed.
Possible compatibility issues
- Components now use microtasks to perform updates asynchronously instead of setTimeout. Since microtasks are run before the browser repaints the page, all loaded components will be initialized and displayed in a single repaint. Although this reduces the overall time needed to display components, it could result in a longer delay before anything is displayed.
- The new, native deferred updates feature has a slightly different API and is implemented differently than the Deferred Updates plugin. Migrating from the plugin will generally require some code changes (full details to come soon).
- ko.observable and ko.computed no longer use a closure when defining their methods, such as dispose and valueHasMutated. These functions expect this to be set correctly and so can't be used directly as a callback. Instead you'll need to use bind, such as obs.dispose.bind(obs).


I am a student / programmer living in Helsinki and studying bioinformation technology at Aalto University. My interests are in 3D, doing stuff on the GPU and everything that combines mathematics, programming and performance. I have worked mainly with C++ and OpenGL but I'm also pretty strong with python and matlab.
I listed my programming knowledge together with my programming work experience, the programming courses I've completed and other experience that I have.
Check out my project from Basic Course in Programming Y2!
On summer 2019 I worked as a software designer at Image Soft Oy where I continued working part-time during the academic year 2019-2020. My job was graphics-oriented with C++ and OpenGL.
I worked as a course assistant at the basic course in C in spring 2019.
There's info about the group project we did on the C++ course in Projects.
I'm pretty familiar with version control from work and programming courses.
Here are the projects I dare to present publically:
On Basic Course in Programming Y2 we had about two months to write a simple program on python and pyQt5. I crafted a simple software to simulate rigid body collisions in 2D. Arbitrary convex polygons, rectangles and spheres are supported and they can be created inside the program with user given parameters. Additionally the direction of gravity can be changed from a toggle. Watch this nice little demo below:
I used SAT to detect collisions and to determine the collision point. The collisions are handled with the impulse response method.
We made a path tracer as a group project on Object oriented programming with C++. Our team members were Aapo Pajunen, Otto Von Boehm, Sara Barroso and I and we had only one period for this project. I was mostly in charge of creating the GUI in the image below.
In the GUI the user can move freely in a 3D scene. New objects can be added or removed and their position, rotation and size can be edited. Material attributes can be changed as well: color or texture, roughness and emission. The program supports absolute spheres and planes and triangle meshes from Wavefront obj-files. Scenes can be saved to files and loaded through the GUI. Path tracing uses GGX importance sampling and octrees for mesh intersection detection acceleration.
The scene in the image represents a Cornell box with a light emitting roof, diffuse walls, a highly reflective sphere and a semi-glossy dragon.
Below is a path tracer image of the GUI view with 200 samples per pixel.
The GUI uses GLFW3 for opening the window and OpenGL and GLEW for rendering the 3D view in the viewport. Editing fields are created with ImGui. Meshes are loaded with tinyobjloader, glm is used for linear algebra and lodepng loads textures and saves rendered images. OpenMP parallelization is used to multihread path tracing.
The projects I presented above are course projects and thus they can't be published in github. That is why I decided to craft this little web portfolio for myself. I wrote the html document, stylesheet and javascript code with a text editor and drew the svg icons. The site should scale for all mainstream window sizes and work for both phone and desktop. CSS sure can be challenging sometimes!

Here you'll find some suggested images that you can use, or feel free to create your own, as Bitcoin Cash is decentralized.
To the right is a list of collections or albums, each providing many different high quality formats. The images below were sourced from these collections.
Bitcoin Cash is peer-to-peer electronic cash for the Internet. It is fully decentralized, with no central bank and requires no trusted third parties to operate. Visit the BitcoinCash.org website to learn more.
There are a multitude of ways, however the most common and easiest method would be to purchase it online via an exchange, or similar service. Check the "Crypto Exchanges" and "Crypto Services" sections on this site where you'll find a plethora of options to acquire Bitcoin Cash from those who support it.
Yes. Bitcoin Cash is the continuation of the Bitcoin project as peer-to-peer digital cash. It is a fork of the Bitcoin blockchain ledger, with upgraded consensus rules that allow it to grow and scale.
Anyone who held Bitcoin at the time Bitcoin Cash was created became owners of Bitcoin Cash. This means that Bitcoin holders as of block 478558 (August 1st, 2017 about 13:16 UTC) have the same amount of Bitcoin Cash as they had Bitcoin at that time. If your Bitcoins are stored by a third party such as an exchange, then you must inquire with them about your Bitcoin Cash.
Any transactions after the August 1st ledger split are completely separate between Bitcoin and Bitcoin Cash. This means any Bitcoin acquired after the split does not include any Bitcoin Cash, and any Bitcoin Cash does not include any Bitcoin.

SmartTraveller devotes in building platforms for both tour guides and travelers. I joined SmartTraveller as the first designer and hired key talent for the design team. Our design team worked closely with marketing department. I participated in product strategy and supported product promotion plans.
Our first website released last March and got really good traffic, but only one out of ten checked our customized service. Based on our google analytic and users’ feedback, we separate our website to a forum for young users to share their journey tips and our customized service for senior users in different styles.
Guess which is for whom?
We promoted the forum on Weibo and Wechat to grow our community, and promoted our customized service on local media for more influential cooperation. The strategy worked well.

by Curtis Edmonds --<EMAIL_ADDRESS>The 1990's will be remembered in twenty-first century film schools as the Decade of the Digital Disaster. This is the time when new advances in computer graphics and modeling are leading to... well, not bigger and better movies, but bigger and better explosions, anyway. Like any good group of little boys, the disaster moviemakers are using their powerful new tools to take things apart and blow them up. Want to see the White House explode by an alien attack? Want to see a great green atomic lizard flatten New York skyscrapers? Want to see a giant tidal wave wash away the Brooklyn Bridge? You want it, the CGI boys can do it. (Although God knows why they're so hard on New York.)
But it's one thing to have these new toys, and quite another to make good movies with them. Snappy computer graphics can't save movies without believable storylines or interesting characters -- case in point: Alex Proyas's Dark City -- while the same quality graphics integrated with classy acting and writing (and all the other things that Titanic had going for it) can make a movie magical.
Somewhere right in the middle is Deep Impact. The graphics quality is first-rate, although most of it is at the end of the movie, and the filmmakers wisely limit the scenes of death and devastation. Deep Impact takes the road less traveled in disaster genre movies, choosing to focus on people and their relationships instead of action and suspense. While other movies have concentrated on the wholesale destruction of landmarks and cities, Deep Impact saves much of its concern for the destruction of families and friendships. While it's possible to sit back, munching popcorn, contemplating the destruction of a digital Manhattan with an awed "Cool," there's something moving about the ending of human relationships, no matter how badly or inexpertly handled.
The problem with Deep Impact isn't the genuinely touching and wrenching moments, easily the best part of the movie. The moments and the emotions would be there no matter how well the movie was written. The problem is that the people we follow throughout the movie almost seem to be chosen at random: the crew of the space vessel sent to stop the comet, the family of the teenage astronomer who discovers the comet, the MSNBC news team who follows the story: The end result is something reminiscent of Tim Burton's Mars Attacks!, another end-of-the-world epic with a large and unwieldy ensemble cast. (Any other similarity is incidental, Deep Impact is nothing if not sincere, and levity is sorely lacking.) And by picking a large number of ordinary people to suffer through the end of the world, what you get is a very ordinary movie.
It doesn't really help that almost everyone in the movie is a refugee from NBC's Thursday night lineup. (It certainly doesn't help that the MSNBC network is referenced at every conceivable point.) Most notably, you have Tea Leoni (The Naked Truth), a gifted comic actor who looks woefully stiff and out of place behind the anchor desk. Throw in Bruce Weitz (Hill Street Blues) and Laura Innes (ER) on the news team, and Ron Eldard (ER), Blair Underwood (L.A. Law) and Jon Favreau (Friends) aboard the oddly-named Messiah spacecraft, and what you have is a Must See TV-Movie.
The two leads are, thankfully, America's Greatest Actor -- Morgan Freeman -- and Robert Duvall, who's not that far behind. Unfortunately -- and this is a chronic complaint of mine -- neither of them are given enough to do. Freeman is the President, but (outside of an early conflict with Leoni) he is never seen doing anything Presidential. He is the oracle, the narrator, providing reassurance, oratory, and plot points. Which is fine, and he's great, but it's not enough. On the other hand, Duvall is at the heart of the action, aboard the spacecraft, and he is -- Chuck Yeager! Yes! Supercool, lollygagging around up there in outer space, the sole standard-bearer for Tom Wolfe's righteous stuff, all ready for the next comet landing or spark plug commercial... and it's a mold that he never breaks out of. I suppose parts like this are the price that Duvall -- and the rest of us -- have to pay for the privilege of movies like The Apostle, so I won't comment too severely on his choice of scripts.
The one thing I took out of the theater from Deep Impact was the sterling quality of the THX system in Austin's Lincoln 6 theater. Whenever the camera pans past the comet in space, the THX emits this rumble that made the walls shake -- sort of like a low-level Sensurround. (Never mind that real comets couldn't possibly make that rumble in the soundless vacuum of outer space.) Despite the movie's refreshing attention to relationships over explosions (there's only one completely mindless and extraneous explosion, early in the film), when the standout part of the movie is the sound system, something's missing. There's a lot missing from Deep Impact, a perfectly ordinary and middle-of-the-road disaster flick in every regard.
