What does this have to do with this debate? Or are you just going to the usual argument of sales even though no one was even debating that. Who even brought up the issue of which console is selling better?
The thread has been completely derailed by graphics discussions. I was basically insisting people knock it off.
But the sales argument is due to the fact that, last I checked, this is a thread about where KH3 will go and I believe that, due to the Wii's overwhelming sales, it'll be the Wii.
Oh is that why all the big 3rd party games are going to Wii? Oh wait a second...
Heh, no big games are going to the PS3 and 360 because development on them started more than a year ago. Developers are now getting terrified of the Wii, and scrambling to shift focus. Every company except Konami has anounced the Wii is their primary development focus. Konami has anounced they are working on a new hardcore Wii RPG.
The Wii is the DS ckmlb. The comparisons are so close it's scary. The 360 and the PS3 together are the PSP. Where is the 3rd party support 3 years down the line? Heh, well I'll let you go count for yourself. Where was it at first? Let's just say developers better hope that sales trends change and change fast, as their 3rd party bombed really hard on the PSP, while Nintendo was supported by first party. 2 years later the PSP is all but forgotten from the development standpoint. It's flooded with ports and remakes and 2 Square Enix games. Believe me, I have trouble finding anything to buy for my PSP. The last game I bought was Mega Man Powered Up. I have 2 Square Enix games to look forward to... and that's it.
If the Wii ends up with the kind of support the DS gets, I'm very happy with my purchase. If it doesn't, I'll still get the flood of great Nintendo titles the DS got, but I'm really not worried about it at all.
You're jumping the gun a little here. Really predicting the worse for hte 360 and PS3 and the best case scenario for the Wii.
All the publishers are focusing on the Wii but what kind of games are they making? Casual oriented ones. Hence the big games will come to PS3 and 360 still with spinoffs going to Wii and the casual stuff more and more going to Wii.
Just look at SC IV, they had a chance to make it on Wii but they announced it on 360 and PS3. Why? This game was just revealed and is extremely early in development and could have been shifted to Wii.
Edit: Also you only need to look to find the great games on PSP, but clearly you are not and resigning yourself to 'oh no only ports and two Square games coming'. Are you even looking?
Thanks to Blacksaber for the sig!

The ps3 will surely obtain the game, but there is a possibility it may come out on the wii. The reason is sales. Square enix goes for the best selling console they dont go loyal for one specific company, or I may be worong I expect the wii to get kingdomhearts no matter what the hapenings, thats if the ps3 doesnt get final fantasy Xii as an exclusive game.

No one is saying every hardcore game is going to the Wii. Only the most delusioned would say MGS4, FFXIII, etc. are going to have any Wii version whatsoever. Obviously the Wii fanbase has some hardcore, Resident Evil 4 sold amazingly well for being a 2 year old game.
On the other hand, if you would actually read the topic instead of assume that everyone is saying it will go to the Wii just because they want it to, you would see that there are a lot of good reasons for it to go to the Wii. Demographic and user base being the biggest ones. I never met a single person who bought KH when I was in high school, and I doubt all of the 13-18 year old kids with PS3s and 360s are going to be buying it. Square Enix seems to be very good at hitting target demographics (for example DQIX on the DS) and I think they are very aware that the demographic that plays Kingdom Hearts is younger and older than the demographic of PS360 owners. Add to that the fact that the game breaks 1 million in Japan (and it can't sell more than 1 million on either the PS3 or 360 in Japan) and the fact that the Wii is strongest in the 2 markets that KH sold best (America and Japan) and the Wii is the logical choice for a platform. You don't even have to worry about it sacrificing the graphics, as the art style of the game doesn't require powerful graphics to look good. The game is such a perfect fit on the Wii it's almost scary. It seems like it could have been made knowing that the Wii was comming lol.
So this whole graphics debate was so you can convince people it will look as good on Wii as it would on PS3 and 360? It wouldn't. Not saying it won't look good, just not as good...
What is this BS about PS3 owners all being 13-18 year olds? You think the average teen ager can afford a PS3 at the current price?
Also the assumption that teens don't buy Kingdom Hearts games is not necessarily as true as some people are contending it to be.
No, I don't think the average 13-18 year old can afford to buy a PS3. That might explain the horrible sales, considering their target demographic can't afford their system.
Yes, I'm jumping the gun a little. I'll admit that currently the direction of development is just the most likely scenario, rather than anything close to guaranteed. However, remember it took 2 years of bad sales for developers to realize they couldn't sell games on the PSP. So actually, SCIV is staying within the DS/PSP trends.
As far as what the Wii is getting from 3rd parties, you have NO CLUE. Stop saying they are all casual games, because last time I checked, you couldn't see into the future, and developmental focus has shifted within the last 2 months. So, how about we don't talk shit about imaginary games?
Yeah I look for good games, I just see too many racers, shooters, and sports games: None of which I play (other than the occaissional well made shooter, and all handheld shooters blow). But, again, we are far off track. Let's get back to the discussion.
So, since people like to simply dodge the reasoning and attack the Wii's current development trends, here are the only solutions I have heard and why:
PS3 or 360:
-Pro: apparently movie game sales mean it will sell well? Graphics could be good.
-Con: very few systems sold, high development costs, graphics won't improve much for the increased cost, demograhic doesn't match well (this is a matter of opinion, but my personal experience is the majority of PS360 owners are between the ages 13-18. A few more up to 25), no Japanese sales
PS3 and 360:
-Pro: Graphics could be good, 2 systems combined wouldn't be far from Wii sales (other than in Japan, where the game is also popular), movie games sell well argument again (still not understanding this)
-Con: No Japanese sales, Square Enix has a history of keeping individual games in their major franchises exclusive (every FF game, every DQ game, and ever KH game) other than future remakes, doesn't match demographic well (even if you won't admit the majority is between 13 and 18, you can admit they have almost none of the under 13), high development costs, not far improved graphics over a Wii version
Wii, PS3, and 360:
Who are we kidding, this isn't gonna happen.
-Pro: large user base especially in the 2 areas the game sells the best (America and Japan), cheap development costs, matching demographic (under 13, over 18), graphically more than capable of displaying detailed and improved cartoon graphics
-Con: um... you guys don't like the Wii? Graphics won't be quite as good... you guys still don't like the Wii? If development began more than a year ago they won't cancel it now, oh and apparently because Spider-Man 3 didn't sell well, KH3 won't.
Anything you guys want to add to any of those categories?

Yeah, I'll add some more... Final Fantasy 13 is coming for the PS3 and will likely greatly expand the PS3s rpg audience. That *same* audience will likely buy the next Kingdom Hearts as well. So you can't honestly claim it wouldn't have any sales in Japan.
Also there may be other *unforseen* reasons why it might end up on another console. Wouldn't it be shocking if they announced it for the 360? Why did I mention that console? Well Microsoft has publicly stated they're going to try to get and make more games for a younger and casual audiences and they're also trying to get games that attract Japanese gamers. What would be a better exclusive to try to get than Kingdom Hearts that fits exactly what they're looking for?
Legend11 said:
Wouldn't you say Dragon Quest does the same for Nintendo audiences? Even moreso the KH developers creating a DS game shows a reasonable connection to the Nintendo systems (obviously DS and PSP could still be an option). Of course there are unforseeable situations such as microsoft paying for the game, but I would say that's an unlikely scenario.

Oh, WOOOOOOOOW. One main series title and one spin-off (FF Versus XIII). ZOMG!! TOTAL SUPPORT!!!!.... Not.
Edit: Oh, and TLR which is also a spin-off and is multi-platform.
megaxl said:
square enix have childrens of Sony i think lol, for that kh3 be a ps3 game, and maybe square gives sony final fantasy XIV, XV, XVI, XVI, and all the new big IP
Ummm, they probably won't even GET to XIV because they have Fabula Nova Crystallis going on which games are going to PS3, Wii, PSP (maybe), DS, 360 (maybe)
WiiGirl76 said:
PS3 + PS3, simply because those games are hardcore and Nintendo only gets junk or simple spin off games from Square Enix... or remakes. But you honestly don't expect an exclusive KH3 on the WII now don't you? If that will happen, it would be serious world news.
HAHAHAHAHAHAHAHA!!! KH....hardcore? Where was I when they announced this? KH isn't hardcore at all. And it won't be world news to most people 'cause they knew it was coming. Maybe world news to the Sony fanboys, though >_> How about you stop being a little girl and get along with facts?
Edit: The PS2 was a non-hardcore game system, FYI.
You think that Square is going to break a 20 year trend of no dual platform games, so that you can play it on the 360. You site movie games as the reason (with one of your examples complete BS), and higher attach rates in the countries that it sells (which isn't true at all). I'm sorry, but the only situation I see of KH3 not being on the Wii is if development began more than a year ago. Otherwise, the spinoff will be on the PS3, and the 360 will probably get nothing (they aren't going to sacrifice 1.2 million Japanese sales for the 360 to get the game).
Have you not heard of The Last Remnant, a DUAL platform game for the PS3 and 360? I'm willing to bet the game will sell *a lot* on the 360 and PS3.
*Edit: Oops I guess you meant primary series but I can't understand the logic behind that if they're willing to do ports and remakes of games on just about every platform and also have a multi-platform game in development for the PS3 and 360 and have mentioned that the Unreal 3 engine keeps down costs, that it would be so impossible to believe that they'd make other multi-platform titles. I mean if Capcom is now doing it with their Resident Evil franchise and many many other developers are making multi-platform titles with their major series for the PS3 and 360 why not Square? As for them not breaking traditions, I remember people saying they'd never leave Nintendo's platform (that was right up until the big FF7 shocker was dropped on the public).
Why the hell would they use UE3 on a KH game? Don't say"TEG GRAFIX" because the Disney demographic in the game doesn't cut it when using UE3. Disney is cartoons not HD.

Q: Pepper android sdk emulator error on ubuntu 18.04 I am trying to start the robot-emulator from pepper android sdk. But i am having this error when i try to start the emulator.
Below is the error i am getting
ROBOT_VIEWER_EMULATOR : /home/hassaan/.local/share/Softbank Robotics/RobotSDK/API 4/tools/bin/robot_viewer: /home/hassaan/.local/share/Softbank Robotics/RobotSDK/API 4/tools/bin/../lib/libz.so.1: version `ZLIB_1.2.9' not found (required by /usr/lib/x86_64-linux-gnu/libpng16.so.16)

Has anyone run in the same issue.

A: *

*Make sure your user is in the kvm group.

You need to first install this:
sudo apt install qemu-kvm

To check the ownership of /dev/kvm use:
ls -al /dev/kvm

The user was root, the group kvm. To check which users are in the kvm group, use
grep kvm /etc/group

This returned
kvm:x:some_number:

on my system: as there is nothing rightwards of the final " : ", there are no users in the kvm group.
To add the user yourname to the kvm group, you could use
sudo adduser yourname kvm

which adds the user to the group, and check once again with grep kvm /etc/group.
You might want to log out and back in (or restart) for the permissions to take effect.

*Relink the correct libz.so

Go to: /home/yourname/.local/share/Softbank Robotics/RobotSDK/API 4/tools/lib
Back up the old libz.so.1:
mv libz.so.1 libz.so.1.bak

And relink the system's one:
ln -s /usr/lib/x86_64-linux-gnu/libz.so libz.so.1

*Restart Android Studio

You should now be able to start the Pepper emulator!

'Tyger! Tyger! burning bright
Okay, maybe a bit of a cliche, but somehow Blake's poetic homage to the paradox of creation, with its tiger the symbol of spiritual revolt backed by uninhibited natural energy, seems to encapsulate something of the mood created in this stunning second novel by Polly Clark.
I imagine every novelist strives to create that elusive of things - the perfect novel. What is the perfect novel? I'm not sure. I have no definitive answers but my gut is telling me that this story sure as hell comes close.
It's beautifully structured for a start. A mood setting prologue. Three seemingly, disparate initially, people stories. Four sections. All beautifully written with an economic yet substantial prose style which effortlessly conveys a depth of emotion allowing the reader to peel back the layers of these people and care about them. Subtly understated and nuanced is the thread that links these three people. It's never obvious but the astute reader will start to make the connections and will ultimately be rewarded for it as the book heads towards its conclusion. Underlying it all though, is a deep, profound love and reverence for the natural world and its inhabitants. And the tigers. Always the tigers.
'Not far, now. Trailing glittering dust from its wing tips, an owl lifted. Two planetary gazes met. Two intelligences: one of air and night; one of snow and dawn.
Of course the stars of the show are the tigers, rightly so. Is this the literary 'Year of the Tiger'? Yangtze Choo's The Night Tiger hasn't left my system yet! Most impressive is not merely the meticulous research but the perceptive understanding of how such a majestic and magnificent animal exists. Somehow this writer has gone beyond simply describing the tigers to the extent you feel she has been able to get inside their heads and share with the reader exactly how these animals live and think. The descriptions are real, they're palpable. Yet it seems that the tigers are there as symbols for our fragmented lives. The tigers' ability to kill physically belies their potential to heal emotionally.
It's a book about survival; extreme conditions, freezing temperatures, scarcity of food. The hunter and the hunted. The raw insignificance of a human compared to the natural world and the tigers.
'The hunter exists outside nature. He changes nature to suit himself. He burns it, chops it, digs it, destroys it. He disguises his own weakness with things he has made: snares, traps, guns.'
But however much reverence for the tiger is the integral thrust of the book Ms. Clark never loses sight of the human condition and as such you have a fiction that is beautifully balanced.
'My mistake was not that I didn't try to give my all, myself… whatever the fuck way you just put it. It's that …it's that…' She put her fists to her temples in frustration. 'It's that I did!'
The balance is further struck because the book can be appreciated on a number of levels. 'Just' a story if that's all you want but it also raises issues of conservation and the human responsibility for species in jeopardy. It's about the natural world, the paradox of an hostile beauty that makes survival perilous. And It's a story of people, our need and dependence on each other no matter how much we hurt or get hurt in the process, It's about love.
The closest most of us will get to a tiger are perhaps our domestic tabby cats?!?! Somehow reading a book like this changes the way you think about them!
My thanks to NB Magazine/Nudge Books for a proof of this remarkable story.

A blog on the U.S.-Russia relationship
Nuclear Weapons: What Does Russian Orthodox Church and Its Top Parishioner Believe?
Simon Saradzhyan
This week, Russian President Vladimir Putin proclaimed in his written address to the Tenth Review Conference of the Non-Proliferation Treaty (NPT) that he "believe[s] that a nuclear war cannot be won and must never be fought, and we stand for equal and indivisible security for all members of the world community." Interestingly enough, there was no such coupling in Putin's address to the previous NPT Review Conference in 2015. In fact, "indivisible security," which has become one of the Kremlin's favorite principles when expressing grievances vis-à-vis the West, was absent from that 2015 address. Perhaps this new coupling indicates that Putin wants the world to know that according to Russia, preventing nuclear war should be indivisible from ensuring that no country can enhance its own security at Russia's expense. If so, that would not be inconsistent with Putin's and his team's efforts to implicitly threaten the use of nuclear weapons over the West's assistance to Ukraine.
It would, perhaps, be just as interesting to know what Putin, as a practicing member of the Russian Orthodox Church (ROC), may believe when it comes to nuclear war. For clues on that, one can read Dmitry Adamsky's profound "Russian Nuclear Orthodoxy" volume. Or one can skim the statements on the issue, gathered below, made by the ROC's leadership and Putin's apparent confessor. These statements, gathered from various sources, indicate that the ROC has nothing quite as extensive, long and thoughtful as the Catholic Church's just war theory in general or Catholics' views on nuclear weapons. Overall, if these statements (and blessings) are any guide, the ROC appears to be significantly more tolerant of nuclear weapons than the Catholic Church.
Incumbent Patriarch of Moscow and all Rus' and Primate of the Russian Orthodox Church (2008-present), Kirill, on nuclear weapons and their use/nonuse:
Kirill said in 2009: "Today, the weapons that are being developed in Sarov constitute a deterrence factor. We must strive for a world without weapons, but we should do so in a way that will ensure that this desire does not destroy ... our country, so that we retain the opportunity to remain a sovereign state."
Kirill said in 2022: "As for relations between the East and West, we are all interested in, of course, maintaining peace, so that the formidable and destructive weapons that are available today ... will never be put into action." Kirill was also quoted as saying that a war today could entail the end of human history and that the availability of nuclear weapons can turn conflicts into a global tragedy.
Kirill's predecessor Alexy II (1999-2008) on nuclear weapons and their use/nonuse:
Alexy II (served as the patriarch from 1990 till his death in 2008) in 1996 co-organized a conference titled "Nuclear Weapons and Russian National Security." He and then-Metropolitan (and future patriarch) Kirill orchestrated the event. "Their opening statements, which dubbed the nuclear weapons specialists 'the eremites' (podvizhniki), proclaimed its credo: to assist the nuclear complex in overcoming the most pressing problems, to ensure its influence in national security policy, and to cultivate a respectful image of it among the Russian public," according to Israeli scholar Dmitry Adamsky.1
Alexy II said in 1996 during a forum on nuclear weapons: "All sensible people believed and continue to believe that the unrestrained arms race must be stopped. But at the same time, we must pursue a sober approach towards the surrounding reality. We all will have to live side by side with nuclear weapons, which play an essential role in ensuring security, for a long time to come."
Alexy II said (undated): "We need to strive for the speedy conclusion of treaties on the prohibition of nuclear, chemical and bacteriological weapons."
Alexy II said in 2007: "In Sarov, which is the cradle of the nuclear weapons complex, an all-Russian shrine was restored—the world's first cathedral of St. Seraphim of Sarov. So let him from now on be the heavenly patron of all of you and the nuclear weapons complex as a whole... I pray to the Lord and to Seraphim of Sarov so that the nuclear weapons, which are being created and entrusted to you, will always be in the hands of God and remain only a weapon of deterrence and retribution."
Alexy II wrote in 2007: "I heartily congratulate you on the 60th anniversary of the founding of the 12th Main Directorate of the Ministry of Defense—the main structure of the Russian nuclear weapons complex! At the cost of considerable sacrifices, your selfless work has made it possible to successfully solve a set of tasks related to maintaining the nuclear potential of all branches and arms of the Armed Forces at a level that reliably guarantees the military-strategic security of Russia and the countries of the Commonwealth of Independent States."
Vsevold Chaplin, who served as chairman of the Synodal Department for the Cooperation of Church and Society of the Moscow Patriarchate under Alexy II, wrote in 2007: "Any weapon, especially a nuclear weapon, is evil. But this evil, alas, is inevitable in a world corrupted by sin, where, until the second coming of the Lord, there will be a struggle for power, clashes between peoples."
Putin's apparent confessor, Metropolitan of Pskov and Porkhov Tikhon (Shevkunov), on nuclear weapons and their use/nonuse:
Tikhon—who has reportedly received 20 billion rubles (some $327 million) from authorities and state-owned companies in Putin's Russia for his projects - appeared to praise Stalin for overseeing the creation of a Soviet nuclear bomb in his 2019 open lecture, citing an adage attributed to Churchill: "Stalin inherited Russia with a wooden plough and left it with an atomic bomb."2
Tikhon referred to "the atomic weapons, with which overseas and European forces are threatening us" in a March 2022 sermon that focused on the war in Ukraine, but did not elaborate.
In 2006, during celebrations at one of the 12th GUMO's nuclear polygons in northern Russia, Tikhon consecrated a church on an adjacent garrison's territory as well as the polygon's equipment.3
In 2010, Tikhon consecrated the first of the Project 885 (NATO code: Severodvinsk) series of the Russian Navy's nuclear-powered cruise missile submarines.
The only scientist to serve on the ROC's Council on Culture, of which Tikhon was the secretary, was Rady Il'kaev, the scientific director of the Russian Federal Nuclear Center—All-Russian Scientific Research Institute of Experimental Physics (RFNC-VNIIEF),4 which is located in Sarov.
The collective leadership of the ROC on nuclear weapons and their use/nonuse: In 2020, the ROC published a draft of regulations, "On Giving Orthodox Christians Blessing for Performance of Military Duty." That initial 2020 draft banned "'consecration' of any kind of weapons, the use of which can lead to the death of an indefinite number of people, including weapons of indiscriminate action and weapons of mass destruction." When commenting on the 2021 draft of the regulations, Archimandrite Philip Ryabykh confirmed that the draft still contained that ban. "Blessing of personal weapons is allowed, while other types of weapons are supposed to be sprinkled with holy water. Perhaps in the future there will be weapons even more terrible and destructive than nuclear weapons. That is why the members of the church assembly decided not to identify individual types of weapons," said Ryabykh, who served as a representative of the Moscow Patriarchate to European organizations. However, commenting on the 2022 draft of the regulations, Archpriest Mikhail Vasiliev, who serves as the ROC's representative to the Strategic Missile Forces, denied that the regulations, which will reportedly be reviewed by the church's Holy Synod in either fall or winter 2022, would ban the consecration of weapons.

Q: Factoring $1+x+\dots +x^n$ into a product of polynomials with positive coefficients
Can the polynomial $1+x+x^2+\dots +x^n$ be factored, for some $n\ge 1$, into a product of two non-constant polynomials with positive coefficients?

Thoughts
It is easy to factor it into polynomials with non-negative coefficients e.g.
$$
1+x+x^2+x^3 = (1+x)(1+0x + x^2),
$$
but I have no example with positive coefficients. I believe this should be possible for large $n$, since there are so many (something like $2^{\lceil n/2\rceil-1}$) ways to factor $1+x + x^2 +\dots + x^n$ into a product of two monic polynomials with real coefficients.
Some motivation from probability theory
The question is motivated by Can the sum of two independent r.v.'s with convex support be uniformly distributed?
Namely, we can ask ourselves a discrete counterpart:

Whether a discrete uniform random variable (i.e. the one taking values $0,1,\dots,n$ with equal probabilities) can be decomposed into a sum of independent non-constant random variables, each ranging over a set of consecutive integers?

The link is provided by the probability generating function (pgf):
$$
m_Y(x) = \mathbb E[x^{Y}].
$$
If the random variable $Y$ takes values $0,1,\dots,k$ with positive probabilities, then its pgf is a polynomial with positive coefficients:
$$
m_Y(x) = \sum_{i=0}^k \mathbb{P}(Y=i) x^i;
$$
in particular, for a random variable $U_n$, uniformly distributed on $\{0,1,\dots,n\}$,
$$
m_{U_n}(x) = \frac1{n+1}\bigl(1+x+x^2+\dots + x^n\bigr).
$$
Since for independent random variables, the pgf of sum if a product of pgfs:
$$
m_{Y'+Y''}(x) = \mathbb E[x^{Y'+Y''}] = \mathbb E[x^{Y'}]\mathbb E[x^{Y''}] = m_{Y'}(x)m_{Y''}(x),\tag{1}
$$
these two questions are equivalent$^*$.

$^*$Note that in general $(1)$ does not imply the independence of $Y'$ and $Y''$. Nevertheless, if $m_Y$ factors, say, into $m_{Y'}$ and $m_{Y''}$, then $Y$ has the same distribution as the sum of independent copies of $Y'$ and $Y''$, and, indeed, we have the desired decomposition.

A:
Can the polynomial $1+x+x^2+\dots +x^n$ be factored, for some $n\ge 1$, into a product of two non-constant polynomials with positive coefficients?

$$x^n+\cdots +x+1=\frac{x^{n+1}-1}{x-1}=\frac{\prod_{1\le k\le n+1}(x - e^{2i\pi k/(n+1)})}{x-1}=\prod_{1\le k\lt n+1}(x - e^{2i\pi k/(n+1)})$$
For a factorization $x^n+\dots +x+1=g(x)h(x)$, $g$ and $h$ are products of some $x-\zeta^k$ where $\zeta$ is nth root of unity (up to units (in this case multiplying by positive real numbers) however any such factorization implies one without units). The leading term of both polynomials must be $1$ because it is the product of leading terms that are always $1$. The constant term is also one because it is the product of root of unity so its absolute value is $1$ and it must be real and positive.
$$(x^p+\cdots +1)(x^q+\cdots+1)=x^n+\cdots +x+1$$
Assume without loss of generality that $p\ge q$. Take the constant term of the first polynomial and multiply it with the leading term of the second and you get $x^q$.
$$\begin{align}
(x^p+\cdots+ ax^q +\cdots +1)(x^q+\cdots+1) &=\cdots +ax^q1+ \cdots +1x^q +\cdots\\
&= \cdots +(\cdots+a+1)x^q \\
\end{align}$$
All other terms must be positive and they can only add to $x^q$, the coefficient should be equal $1$. Therefore all other coefficients of $x^q$ must be zero and $a$ is zero.

A:
I believe this should be possible for large $n$, since there are so many (something like $2^{\lceil n/2\rceil-1}$) ways to factor $1+x + x^2 +\dots + x^n$ into a product of two monic polynomials with real coefficients.

Nice exercise :): show that $1+x+\cdots+x^n$ can be factored into $2$ polynomials of degree at least $1$ with non-negative coefficients if and only if $n+1$ is not prime.
Probabilistic reformulation: Let $n \geq 2$ be an integer, $X$ a random variable following the uniform distribution on $\{1,2,\ldots,n\}$. Show that there exist two independent nonnegative integer-valued independent random variables $Y$ and $Z$ such that $X$ and $Y+Z$ have the same distribution if and only if $n$ is not prime.

Synopsis: In a dingy motel in the middle of nowhere, a bank robber hold a young attractive girl hostage. Keeping her handcuffed to the bed until he is able to formulate a plan, things go from bad to worse when an escaped convict takes them both prisoner and sets in motion a dangerous and very bloody cat-and-mouse game of one-upmanship. Who wins in the end isn't always about who has control of the gun - but it certainly helps.
Review: If you want a truly suspenseful film and don't want a big budget cast and the over polished look of a Hollywood set then this film is surely the one for you. Now the plot in this film is not necessarily anything that is groundbreaking ,but it does have some twists and turns that will keep you on the edge of your seat throughout including an ending that does have a great payoff. Now when it comes to the cast I think they picked the right people who pulled the film off very well even with some bad dialogue here and there. When it comes to the gore in the film I have to say for what they did it was very realistic ,but I must say this is not a film that relies on gore to make an impact, it relies on atmosphere and a overwhelming claustrophobicfeel. When I say it has a claustrophobic feel I am mainly referring to the scenery because all you as far as that goes is the inside of a motel room for the whole film, which does make you have that feeling the further into the film you go. Overall this is a great low budget thriller that does well with what it's got and truly kept me on the edge of my seat from the start.
