<p><a href="http://111.222.33.4/myPage" rel="nofollow noreferrer">http://111.222.33.4/myPage</a> and <a href="http://111.222.33.4:8080/myPage" rel="nofollow noreferrer">http://111.222.33.4:8080/myPage</a> both serve up myPage properly</p>
<p>Following instructions I found online, I changed the https port (443) to 8443 and modified Tomcat server.conf to cause traffic on port 8443 to</p>
<p>I can access mySecurePage as follows:</p>

If you had your pick of one lost written work (or series of works) from any point in history to be found and translated, what would it be? Explain.. My picks
1: The rest of the epic cycle. Knowing that the Iliad and Odyssey, basically the foundation of western literature were only 1/4 of the story drives me nuts.
2: The original writings of Jesus and his apostles. God damn that would solve so many questions. Actually all the lost works relating to the Bible. The gospel of Eve sounds kinky.
3: The remaining works of Livy. At least half of what we know about Rome came from his histories, and we only have 35 books out of his 140 or so. | 0non-cybersec

Navigation Controllers in UISplitViewController leave space for bottom bar. <p>As the title indicates, I am having an issue when using UINavigationControllers as the Master and Detail view in a UISplitView. The navigation controllers leave space for a bottom bar. When I remove the nav controllers, the views are rendered just fine.</p>
<p>The storyboard looks like:</p>
<p>TabBarController -> SplitView -> UINavigationController (master and detail) -> ViewControllers for each.</p>
<p>I am able to "hack" the view to render properly by adding 40px of extra space as a constraint, but I would rather not do that.</p>
<p>What am I missing?</p>
<p>EDIT: I've mocked everything up in an empty project and it seems to work fine by default. It seems I've changed some setting or doing something in my main project that is causing this issue.</p>

How can a "proper" function have a vertical slope?. <p>Plotting the function <span class="math-container">$f(x)=x^{1/3}$</span> defined for any real number <span class="math-container">$x$</span> gives us:
<a href="https://i.stack.imgur.com/zdDPO.png" rel="noreferrer"><img src="https://i.stack.imgur.com/zdDPO.png" alt="plot of function"></a></p>
<p>Since <span class="math-container">$f$</span> is a function, for any given <span class="math-container">$x$</span> value it maps to a single y value (and not more than one <span class="math-container">$y$</span> value, because that would mean it's not a function as it fails the vertical line test).
This function also has a vertical tangent at <span class="math-container">$x=0$</span>. </p>
<p>My question is: how can we have a function that also has a vertical tangent? To get a vertical tangent we need 2 vertical points, which means that we are not working with a "proper" function as it has multiple y values mapping to a single <span class="math-container">$x$</span>. How is it possible for a "proper" function to have a vertical tangent?</p>
<p>As I understand, in the graph I pasted we cannot take the derivative of x=0 because the slope is vertical, hence we cannot see the instantaneous rate of change of x to y as the y value is not a value (or many values, which ever way you want to look at it). How is it possible to have a perfectly vertical slope on a function? In this case I can imagine a very steep curve at 0.... but vertical?!? I can't wrap my mind around it. How can we get a vertical slope on a non vertical function?</p>

tox uses wrong version of pip when multiple versions of python are installed. <p>I have a build box which supports python 2.4, 2.6 and 2.7. This leads to installing various versions of pips as required in their own python installations. I'm using <code>tox</code> to run tests through <code>setup.py</code>. </p>
<p>Whenever I run a <code>{python2.7_installation_dir}/bin/python setup.py test</code>, this results in a <code>.tox</code> directory. Inside <code>.tox</code> directory I run </p>
<pre><code>py27/bin/pip --version
pip 1.4.1 from {my_package}/.tox/py27/lib/python2.7/site-packages (python 2.7)
[buildbot@BUILD-SERV-01 .tox]# python2.7
Python 2.7.6 (default, Nov 20 2013, 15:33:09)
[GCC 4.1.2 20080704 (Red Hat 4.1.2-54)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import pip
>>> pip.__version__
'1.5.2'
</code></pre>
<p>So the version of pip inside .tox directory is 1.4.1 where as pip installed for python interpreter that I'm using to execute the <code>setup.py test</code> is 1.5.2. This leads to errors when running tests as it uses pip to install the directories and some of them come from external sources and in 1.5.2 we need to set explicitly --allow-external --allow-unverified flag for one of the module which doesn't exist in 1.4.1, which results in an error each time i invoke tests through tox.</p>
<p>There is only one python2.7 installation and it is installed from source. But I think it was running pip 1.4.1, but now been upgraded to use 1.5.2. How tox can use the old version? Is there any <code>.pth</code> file or something that could have been left behind which needs clearing up?</p>
<p>I could drop <code>tox</code> and run pytests directly but I'd prefer to run them via <code>tox</code>.<br>
Please let me know if you want to see the logs, I can update the question with the log. </p>

How to use spot instance with amazon elastic beanstalk?. <p>I have one infra that use amazon elastic beanstalk to deploy my application.
I need to scale my app adding some spot instances that EB do not support.</p>

What is the meaning of $1/(D+a)$, where $D$ is the derivative operator?. <p>Today I read the answer to <a href="https://math.stackexchange.com/questions/832348/what-is-the-most-efficient-method-to-evaluate-this-indefinite-integral">this post</a>, in which the poster integrates $x^5e^x$ by making these manipulations with the differential operator $D$: $$\frac1Dx^5e^x=e^x\frac{1}{1+D}x^5=e^x(1-D+D^2+...)x^5$$</p>
<p>which I was amazed by but yet suspicious of. After reading a bit on differential operators, I know a few properties. For example, $D+a$ (where $a$ is constant) is a polynomial differential operator which comes from the differential equation $y'+ay = q(x)$. Also, for polynomials $f$ and $g$, $f(x)\cdot g(x)=h(x)$ implies $h(D)u=f(D) \circ [g(D)u]$ with $u$ being a function and $f(D), g(D), h(D)$ being polynomial differential operators. Since $(1+x) \cdot \frac1{1+x} = 1$, I know that if we applied the operator $(1+D)$ to some function, $\frac{1}{1+D}$ would invert it back to the original function.</p>
<p>However, this still doesn't help me make sense of the meaning of $\frac{1}{1+D}$. For example:</p>
<ol>
<li>If $1+D$ comes from the differential equation $y'+ay+q$, where does $\frac{1}{1+D}$ come from? In other words, if $(1+D)y = 1\cdot y + Dy = y' + y$, how do we compute $\frac{1}{1+D}y$? (Is it even possible, and how does it relate to integration?)</li>
<li>How do we justify the power series of the operator? How do we know there are no convergence issues?</li>

Does draining water out of cauliflower and/or sautéing the cauliflower on a pan for 10-15+ min make the cauliflower lose its nutrients and vitamins?. So lately I’ve been making cauliflower rice like everyday since it’s a good substitute for rice, pizza etc. I’ve been making more cauliflower rice lately but I’ve been asking myself if I lose the nutrients and minerals in the process? So personally what I do is a grate the cauliflower into rice then I put it on a pan at low heat and move it around for 10-15 mins and occasionally I put a lid over it to make it “steam” or “pressure cook” so water gets out of it. Then I take the cauliflower out and put it on a cheesecloth and then squeeze the water out. Then I usually fry it with some eggs and olive oil. In this process do I lose nutrients in the cauliflower. If so what can I do better to drain the water out and keep the nutrients. I hate how it taste when it’s moist and like most of the water out of it so I could enjoy it | 0non-cybersec

C# HttpClient.SendAsync always returns 404 but URL works in browser. <p>I am developing an C# console application for testing whether a URL is valid or not. It works well for most of URLs. But we found that there are some cases the application always got 404 response from target site but the URLs actually work in the browser. And those URLs also works when I tried them in the tools such as DHC (Dev HTTP Client). </p>
<p>In the beginning, I though that this could be the reason of not adding right headers. But after tried using Fiddler to compose a http request with same headers, it works in Fiddler. </p>

Console.ReadKey();
}

{
_httpClient = new HttpClient

Security for bitcoin businesses with Employees. <p>Have been investigating some of the gateway apps and offline systems that are being developed. I was wondering what is the most secure way for a business to conduct itself. Let's use a bar as an example. </p>
<p>I would assume a strategy like this would be a start.</p>
<ol>
<li>Owner creates a cold storage wallet with some read only addresses. I am thinking as this being the safe. (maybe even print some out so employees can easily cash out)</li>
<li>The bar then has an online accessible wallet.</li>
<li>He outfits his mobile devices running one of the online gateways or maybe even the electrum wallets.</li>
<li>Patron is ready to pay, the employee rings up the bill and says $xx.xx </li>
<li>The employee and the patron do their transactions. </li>
</ol>
<p>Here is the question...</p>
<p>How often should the employee dump the coin into the cold storage safe? I would think they would need some in case they needed to reimburse a customer.</p>
<p>What do you guys think is the optimal way for a business of anytime, customers or not should handle their coin?</p>

Random semantic security and bijective PRGs. <p>I'm working through Boneh and Shoup's "Graduate Course in Applied Cryptography", and have just finished reading the chapter on stream ciphers and PRGs.</p>
<p>The first exercise for this chapter introduces the notion of semantic security of a cipher for random plaintext messages. Formally, for a cipher $\mathcal{E}=(E, D)$ defined over $(\mathcal{K}, \mathcal{M}, \mathcal{C})$, we define an attack game where the <em>challenger</em> (instead of the adversary $\mathcal{A}$) chooses two messages $(m_0, m_1) \xleftarrow{R} \mathcal{M}$ uniformly at random from the message space, and encrypts $m_b$ in Experiment $b \in \{0, 1\}$, sending the adversary the resulting ciphertext $c$. $\mathcal{A}$ then sends back a single bit $\hat{b} \in \{0, 1\}$ to end the game. $\mathcal{A}$'s advantage in this game is then defined as </p>
<p>$$
SSRadv[\mathcal{A}, \mathcal{E}] = \left|Pr[\hat{b}=1|b=0] - Pr[\hat{b}=1|b=1]\right|
$$</p>
<p>and $\mathcal{E}$ is said to be semantically secure for random plaintexts if $SSRadv[\mathcal{A}, \mathcal{E}]$ is negligible for any efficient adversary $\mathcal{A}$.</p>
<p>The main body of the question asks about how one would build a cipher $\mathcal{E}'=(E', D')$ defined over $(\mathcal{K}', \mathcal{M}', \mathcal{C}')$ that is semantically secure in the "normal sense" (i.e. in an attack game where the adversary chooses $m_0$ and $m_1$), using an SSR-secure (as defined above) cipher $\mathcal{E}$ as a starting point. For complete context, the problem also states that $\mathcal{K}=\mathcal{K}', \mathcal{M}=\mathcal{M}'$.</p>
<p>Given the topic of the preceding chapter, it feels like a natural solution here is to use a secure PRG $G$. Specifically, let $G$ be a secure PRG defined over $(\mathcal{M}, \mathcal{M})$, and then for a given key $k \in \mathcal{K}$ and message $m \in \mathcal{M}$, define $E'(k, m) = E(k, G(m))$. Intuitively, G transforms any chosen plaintext $m$ into an essentially random element of $\mathcal{M}$, and then the random semantic security of $\mathcal{E}$ implies the semantic security of $\mathcal{E}'$. For brevity, I won't try to spell out the actual security proof here.</p>
<p>My main concern here arises when trying to define what the decryption algorithm $D'$ would look like here. In order to undo the application of $G$, we'd need $G$ to have an inverse, and since $G$ is defined over $(\mathcal{M}, \mathcal{M})$, this implies that $G$ is a bijection. This seems like it would contradict the assumed security of $G$; if we can readily define an inverse for $G$, then we could retrieve any seed from its corresponding image in $G$. </p>
<ol>
<li><p>Is it possible to have a secure PRG $G$ that is also a bijection, and if so are there restrictions on $\mathcal{M}$ (e.g. $\mathcal{M}$ is super-poly in the security parameter, etc.)?</p></li>
<li><p>Is there a different approach to building $\mathcal{E}'$ that gets around this potential security flaw?</p></li>
</ol>

Is the NotHaus conviction (Liberty Dollar) relevant as legal precedent?. <p>Bernard von NotHaus (the creator of the <a href="http://en.wikipedia.org/wiki/Liberty_Dollar">Liberty Dollar</a>) was convicted of violating a U.S. federal law that forbids the minting of a currency by anyone in the U.S. besides the federal government. Might it be claimed that bitcoins are also a currency and their users or creators violate that same law?</p>

Does there exist a first-order theory $T$ and a proof system $\vdash$ such that $T\vDash\phi$ iff $T\vdash\phi$, but $\vdash$ is not complete?. <p>Let $L$ be a first-order language and $T$ a theory in $L$. (Here I take "theory" simply to mean a set of sentences in $L$.) </p>
<p>Under the standard semantics $\vDash_{std}$ and any standard proof system $\vdash_{std}$, we have strong soundness and strong completeness: for all first-order languages $L$ and for all sentences $\phi$ in $L$ and for all theories $T$ in $L$, $T\vDash_{std}\phi$ iff $T\vdash_{std}\phi$.</p>
<p>I'm wondering whether, given $L$, there is always an alternative proof system $\vdash_{*}$ such that there exist theories $T$ in $L$ for which $T\vDash_{std}\phi$ iff $T\vdash_{*}\phi$, even though $\vdash_{*}$ isn't strongly complete -- i.e. even though semantic and syntactic consequence don't coincide hold for <em>all</em> theories $T$.</p>
<p>Perhaps the question is trivial if we pick a silly enough proof system, but I've been away from logic for a while and am getting lost in quantifiers (does the language matter?). Perhaps one strategy is to imagine ditching some of the axioms or inference rules of a standard axiomatic proof system: we'll lose completeness of $\vdash_{std}$, so we'll lose the semantics-syntax correspondence on some theories, but will we necessarily lose it on <em>all</em> theories?</p>
<p>If the question is trivial, can it be perturbed to something interesting nearby?</p>
<hr>
<p><strong>EDIT</strong>: Per my own example (take $T$ to be $\left\{\forall x(x\neq x)\right\}$ and $\vdash_{*}$ to be the standard system without quantifier axioms, except for universal instantiation) and that of user Apostolos (take $T$ to be complete in the sense of containing, for each sentence $\phi$, either $\phi$ or its negation, and let $\vdash_{*}$ be the empty system, with no rules and no axioms), the answer to the question in the title is <em>yes</em>. </p>
<p>But what if we require $T$ to be consistent and $\vdash_{*}$ to be nonempty (i.e. to have some axioms and inference rules)?</p>

Anyone else feel like building another PC once done with yours?. I have so far built 2 computers within a couple months timeframe, last one being built around a month ago. I'm already itching on building an entirely new system, I just love the experience of putting together all the shiny new parts and doing all the cable management. Then being satisfied to have it work first boot.
I currently have a 970 and planning a sli 980 build whenever I can scrap together $3000 (Aud). I feel greedy with myself, always wanting more when I have PERFECTLY enough for what I need. If I had the money, I would build a 4 980ti sli build just because I can, and well because I'm probably stupid.
How can I stop this increasing addiction/desire to build a PC and instead use my money wisely? | 0non-cybersec

To anybody who is unsure if they want to build a PC, your hesitation is justified. There is a post at the top of this subreddit right now that I wanted to add to, but felt like creating a separate post regarding it would be best. Here is the post in question: [To anybody who is unsure if they want to build a PC...](https://www.reddit.com/r/buildapc/comments/hm5trz/to_anybody_who_is_unsure_if_they_want_to_build_a/)
​
'\*' = Preceding points are demonstrated within the comments section.
I fully encourage those of you who are anxious about PC building to utilize this subreddit to its fullest extent. The existence of this place, the wiki in particular, is a genuine human achievement. There is just no possible way to build a PC for the first time without enlisting the help of others. Period. YouTube videos and forums are useful tools for troubleshooting and general research, but there is a likelihood that your specific build is unique to you. This uniqueness is going to bring a unique set of problems that are unique to your build. Having access to and utilizing a community such as this one is going to be astronomically important to you throughout the building process, so being kind and being detailed to the users who try to help you can only work in your favor.\*
​
With this said, it is also very likely that you will feel completely alone, nervous, and filled with regret when building and troubleshooting. You may not have access to someone in real life who is willing to help you or knows anything about computer building.\* Those you look towards for help (be it online or in person) may also be stumped, unresponsive, or misunderstanding. You cannot possibly accommodate for every single thing that may or may not go wrong with your build. You cannot possibly know how to word every question you have, how to describe every sound you hear, how to provide a detailed Madden play-by-play of your certain issue and how you got there. There is a very realistic chance that you might have to attempt doing these things at some point and there is a very realistic chance that these things might not lead you anywhere.
​
Building a PC needs to be a calculated risk that you take. You trade the support net provided to you by a singular company selling you a pre-built or a laptop for a patchwork net consisting of the companies you chose for each specific computer part.\* The process of returning your PC parts is long and arduous. Some companies are not as forgiving as others. You may void a warranty, mention something during a live chat that voids your return, or break a part and be subject to the varying kindness of a corporation.\* These are fairly fringe examples, but these things do happen to people -- and you are very much a person. Issues with a specific part of your build may not be apparent, or may produce symptoms in an entire other part rather than the offending one. Your PC is a delicate ecosystem which relies on the stability of each and every participating part.
​
Do not be pressured into going through with a build if you feel that you are not adequately prepared. If you have financial concerns, adjust your performance expectations proportionately. The computer parts market is designed to make you feel like the parts in your price-range, whatever that range may be, are inadequate when compared to a higher tier. This includes YouTube reviewers and public forums such as this one, intentional or not.\* Building a PC is a test of maturity and responsibility; however, choosing not to build a PC is just as much a test of these qualities. When you build your first PC, you are first and foremost spending money on a learning experience. Only after this experience will you then reach the reward at the end. Despite what you all-too-often hear (typically via anecdotal evidence) regarding PC building, nothing about the process is what anyone can rightly consider easy.\* If you jump into this thinking you can wing it, you will regret your decision.
'\*' = Preceding points are demonstrated within the comments section.
​
TLDR: Don't feel bad for not understanding something. Shit happens all the time. Utilize this community and the other resources at your disposal. Building a PC is a big accomplishment and its complexity shouldn't be downplayed.

Uniqueness of a local martingale problem. <p>First, some notation: let $X = (X_{t})_{t\geq 0}$ be some strong Markov process in $E = \mathbb R^n$ with cadlag paths. Let us denote by $P_t$ the transition semigroup of $X$ and by $\mathbb B$ the Banach space of all bounded measurable real-valued functions $f$ with a norm $\|f\| = \sup\limits_{x\in \mathbb E}|f(x)|$. Put:
$$
A f(x) = \lim\limits_{t\downarrow 0}\frac{P_tf(x) - f(x)}{t}\tag{IG}
$$
to be an infinitesimal generator of $P_t$, defined on $\mathscr D(A)\subset \mathbb B$ being the space of function for which the limit in $(\mathrm{IG})$ exists in norm. It is well-known that for any $f\in \mathscr D(A)$ and $x\in E$ the process
$$
C^{f}_t = f(X_t) - f(x)-\int\limits_0^t(Af)(X_s)ds
$$
is a martingale. </p>
<p>For $f\in \mathbb B$ we further say that $f\in\mathscr D(\mathscr A)$ if there is $h\in \mathbb B$ such that for any $x\in E$ the process
$$
C^{f,h}_t = f(X_t) - f(x)-\int\limits_0^t h(X_s)ds
$$
is a <em>local</em> martingale. On $\mathscr D(\mathscr A)$ we define the <em>extended</em> generator as
$$
\mathscr A:f\to h.\tag{EG}
$$
Note that $\mathscr A$ is defined up to some sort of uniqueness: i.e. if $h_1,h_2$ are candidates for $\mathscr A f$ then
$$
\int\limits_0^\infty 1\{s:h_1(X_s) \neq h_2(X_s)\}\;ds = 0 \text{ a.s.}
$$</p>
<p>Conversely, let $(L,\mathscr D(L))$ be some linear operator with $\mathscr D(L)\subset \mathbb B$. The Markov process $Y$ with cadlag paths is said to satisfy the martingale problem with $L$ if
$$
f(Y_t) - f(x)-\int\limits_0^t(Lf)(Y_s)ds \tag{LMP}
$$
is a local martingale for any $x\in E$ and $f\in \mathscr D(L)$. The local martingale problem is said to be well-posed if it has a solution and any two solutions have the same family of finite-dimensional distributions.</p>
<hr>
<p>My question is the following. Suppose we start with some given process $X$ and $\mathscr D(\mathscr A)$ precisely. Clearly, there is at least one solution of the local martingale problem for $\mathscr D(\mathscr A)$ which is given by the process $X$. I wonder if it is unique, or what are the sufficient conditions for the uniqueness.</p>
<p>My thoughts are: since we know $\mathscr D(\mathscr A)$ - we know also $\mathscr D( A)$ and the operator $A$ since $A = \mathscr A$ on the domain of definition of the former operator. Then we can switch to the <em>martingale</em> problem for the infinitesimal generator $A$ rather than dealing with the extended generator and the local martingale problem. I think I've seen somewhere that it such problem then have the unique solution - but I am not sure where have I've seen it and whether it's true.</p>
<p>Any help or hints are appreciated.</p>

Observe that <span class="math-container">$F \wr G$</span> is a full subcategory of <span class="math-container">$F \downarrow G$</span>, my question is: under what conditions does the inclusion admit a left (or possibly right) adjoint? i.e. when is <span class="math-container">$F \wr G$</span> a (co)reflective subcategory of <span class="math-container">$F \downarrow G$</span>?</p>

AFTER YOUVE GIVEN MY STREAM OF CONCIOUSNESS VOMIT COMIT OF A POST THE THOROUGH READING IT DESERVES FEEL FREE TO HIT UP THE COMMENTS AND TELL ME WHAT TRENDS I MISSED, WHAT TRENDS GQ MISSED, WHAT YOU LIKE OR DONT LIKE ABOUT SAID TRENDS AND AND AND (AND IM GONNA HATE MYSELF FOR THIS ONE) FEEL FREE TO ASK ME OR ANYONE FOR BRANDS TO LOOK OUTFOR AND CHEAP ALTS FOR THESE LOOKS YOU CAN ACHIEVE WHILE BALLIN ON A BUDGET

New York Fashion Week: buy a puffer jacket or get out
In all seriousness though its neat to see these trends developing. And what kind of looks are reaching prominence with those with their finger on the pulse of relevant fashion
Trends:
Long overcoats remain in style, but becoming more oversized, closer to lower legs and feet with ever expanding lapels.
Puffer jackets stupidly trendy at the moment. Everyone and their mom has one in the wildest color or material you can imagine.
Leathers and sherpas remain trendy, but worn less aggressively than in the past.
Colors are big. We're seeing more vibrant tones and deep colors. Smooth and mature oaks and shell blues and salmons compete for attention with deep oranges, mustard yellows, emerald greens and other more wacky triatic colors.
Pattern mixing making a huge comeback (along with more mature and weighty materials like wool, boucle, and knits. The drunk 1950s british dad look is both in and gorgious
Along with this is the continued prominence of wider cuts, slouching fits, and sloppy styling of mature pieces for an almost ageless effortless vibe
Shockingly im seeing a sort of quick death of the overbranding trend that struck hard last year. It may have been the rain but i was pleasantly suprisedto notice thay despite the luxe outfits and beautiful pieces on display not many people were plastered with branding or overt logos and graphics
Wacky 2000s and late 90s accessories are making a big comeback. Hit up your local Claire's for the coolest color tinted shades on the block to go with your new colorful wardrobe
Dad shoes OF COURSE are in baby. Ozweegoes, triple S, air max, whatever ungodly poop smeared abomination Gucci just shatout to stay trendy yes baby its daddy's year.
Big boy boots as well too match the thick aesthetic. Chunky chelseas, work boots (paired perfectly with every boys favorite carhartt or Craig green also making waves this year), and doc martens are all solid investments in 2018 the year of our lord
Deconstruction, the eternal Margiela meme machine seems to be thriving off the back of the recent sloppy styling trend. Exposed innards of overcoats, seems falling apart all over, the off white ten making big street appearances on anyone and everyone should tell you where this is going
Workwear/Military brands in general are huge. Or those attempting to capture the look and feel. OAMC, Alyx, Craig Green, Rothco, Carhartt all on the up and up this season
All in all I really like what im seeing and I'm super happy with the direction I see New York Fashion headed in as well as what that means for the rest of us | 0non-cybersec

Ryzen 5 2400g (stock AMD cooler)
Gigabyte GA-AB350N Gaming Wifi
Corsair Vengeance RGB 2x8gb 3000mhz
SilverStone SG13 case
Windows 10 64bit
**Describe your problem. List any error messages and symptoms. Be descriptive.**
Haven't overclocked the APU or memory. XMP is turned off.
Just finished this build and computer is sluggish. After updating BIOS to F22B, it still takes a while to load webpages (20-30 seconds on average). Updated drivers via Gigabyte's website and Windows Update and Device Manager.
Trying to run Prey (2017), I can only run it at 720p Low settings or it crashes.
**List anything you've done in attempt to diagnose or fix the problem.**
I've messed with turning XMP on and running RAM at 3000mhz, but it seems to run the best and most stable with XMP off at 2133mhz.
**Post relevant photos of build/parts here.**
No pics right now.

Recursively counting a parking function. <p><strong>Definition: Parking Function</strong></p>
<p>A parking function of order $n$ is a function $f:\{1,2,\ldots,n\}\rightarrow\{1,2,\ldots,n\}$ such that</p>
<p>$$|\{x:f(x)\le i\}|\ge i\qquad \textrm{for $1\le i\le n$}$$</p>
<p>It is often described using the following scenario: </p>
<p>$n$ cars $\{1,2,\ldots,n\}$ enter a one way street (or parking lot) with $n$ parking spaces. Each car enters the street one at a time <em>in numerical order</em>. They each proceed along the spaces $\{1,2,\ldots , n\}$ <em>in order</em> so that each successive car $x$ either fills its <em>preferred</em> space $f(x)$ or the next available space after $f(x)$. If all cars manage to find a space before exiting the parking lot at the far end then $f$ is called a "parking function". If <em>any</em> car <em>cannot</em> find a space after its preferred space then $f$ is not a parking function.</p>
<hr>
<p>My task is to provide a combinatoric argument for the recursive formula that counts the number of parking functions on $[n+1]$. The formula is given by $$P(n+1)=\sum_{i=0}^{n} \binom{n}{i} (i+1) P(i)P(n-i)$$</p>
<hr>
<p>I know that explicit formula for counting the number of parking function is given by $$P(n) = (n+1)^{n-1}$$ Providing a explanation for the recursion seems to be relate to the concept of dividing the "parking spots" into halves. With the first half having $i$ spots and the second half having $n-i$ spots, but I can't fully relate.</p>

That is, let <span class="math-container">$x$</span> be an n-dimensional object, say <span class="math-container">$N_1\times N_2\times...\times N_n$</span>. I want to take a n-dimensional DFT of this object, by expressing as a product with a DFT matrix as in the case of 1-dimension example in the above figure. What kind of object would the DFT matrix (if i can call it a matrix) be? That defintely not a matrix product but something generalized to handle higher dimensions. Please provide me some theory and directions, or if it already exists, please point me to a reference.</p>
<p>PS : I don't know anything about Tensors, so Ia m not sure if tensors would help.</p>

Closed Polygonal Chains within a circle. <p>The circumference of a circle is divided into N equal parts by N points. How many different closed polygonal chains can be constructed, if they must be made of N segments of the same length, and use all of the N given points as vertices? (A closed polygonal chain is a connected series of line segments that ends at the point where it begins. The line segments may intersect. Two closed polygonal chains are considered identical if one will coincide with the other after rotation.) </p>
<p>how many such unique polygonal chains can be formed for any N? (AKA create a general formula)</p>
<p>Hint (Given to me by teacher): The formula is directly related to Euler's Totient Function</p>

Looking for car opinions. Hey guy, and gals, I am just looking for some opinions on what you think I should buy. I currently drive a 2004 Jeep Rubicon, and although I love it, I need to sell it for a little better of a commuter. I'm looking for something that's sporty but doesn't drink as much gas as my Jeep. Some features I'm looking for are: AWD (front wheel drive might be ok), manual, >20 mpg (city), and must be under $10k. some cars I've been considering are: 2002-04 BMW 330xi, Chevy Cobalt ss, maybe a VW tdi. I'm open to any ideas you have, though I plan on not buying any Asian car except maybe Subaru. I live in Michigan so the AWD or front is a must for winter.
So, whatcha think!? | 0non-cybersec

bg / fg inside a command line loop. <p>ctrl-z (^z) acts in ways I do not understand when done inside a loop executed from a terminal.</p>
<p>Say I type</p>
<pre><code>for ii in {0..100}; do echo $ii; sleep 1; done
</code></pre>
<p>then I hit ^z. I'll get:</p>
<pre><code>[1]+ Stopped sleep 1
</code></pre>
<p>I can resume the job using fg or bg, but the job refers only to he sleep command. The rest of the loop has apparently disappeared, and no more number appear on the terminal.</p>
<p>I could use & after the command to immediately run it in the background, or another solution is to wrap the whole thing in a subshell:</p>
<pre><code>( for ii in {0..100}; do echo $ii; sleep 1; done )
</code></pre>
<p>then ^z gives me</p>
<pre><code>[1]+ Stopped ( for ii in {0..100};
do
echo $ii; sleep 1;
done )
</code></pre>
<p>This job can be resumed and everyone is happy. But I'm not generally in the habit of doing this when running a one-off task, and the question I am asking is why the first behavior happens in the first place. Is there a way to suspend a command-line loop that isn't subshell'd? And what happened to the rest of the loop in the first example? </p>
<p>Note that this is specific to the loop: </p>
<pre><code>echo 1; sleep 5; echo 2
</code></pre>
<p>and hitting ^z during the sleep causes the <code>echo 2</code> to execute:</p>
<pre><code>1
^Z
[2]+ Stopped sleep 5
2
</code></pre>
<p>Or should I just get in the habit of using & and call it dark magic?</p>

Units in quotient of polynomial ring in several variables. <p>Let <span class="math-container">$K$</span> be a field and <span class="math-container">$R = K[x,y]/(xy^2)$</span>.<br>
Let me denote by <span class="math-container">$S^{*}$</span> the set of units of a generic set <span class="math-container">$S$</span>. Moreover let <span class="math-container">$\pi : K[x,y] \to R $</span> be the quotient map.</p>
<p>I'm looking for the units of <span class="math-container">$R$</span>, i.e. <span class="math-container">$R^{*}$</span>.</p>
<ul>
<li>Clearly, <span class="math-container">$K[x,y]^{*} = K^{*} = K \setminus 0$</span> and using <span class="math-container">$\pi$</span> I know that <span class="math-container">$K^{*} \subset R^{*} $</span> (with this I mean that if <span class="math-container">$a \in K[x,y]^{*}$</span> then <span class="math-container">$[a]_{R} \in R^{*}$</span>)</li>
<li><span class="math-container">$[1 \pm x^my]_{R} \in R^{*}$</span>. Indeed <span class="math-container">$(1+x^my)(1-x^my) = 1 - x^{2m}y^2= 1 + xy^2(-x^{2m-1} ) $</span></li>
<li>What else? I mean, maybe there could be oyher units, how can I detect them?</li>
</ul>
<p>Moreover I know that <span class="math-container">$K[x,y]$</span> is UFD and so I have the notion of <span class="math-container">$gcd$</span>: clearly, if <span class="math-container">$f(x,y) \in K[x,y]$</span> and <span class="math-container">$gcd(f(x,y),xy^2)=1$</span> then there exists <span class="math-container">$p(x,y)$</span> and <span class="math-container">$q(x,y)$</span> in <span class="math-container">$K[x,y]$</span> such that <span class="math-container">$p(x,y)f(x,y)+q(x,y)xy^2=1 $</span>. Hence <span class="math-container">$f(x,y)p(x,y) = 1 + xy^2(-q(x,y))$</span>. Now, how can I find an explicit definition of such polynomial <span class="math-container">$f(x,y)$</span>?</p>
<p>Furthermore, if I call <span class="math-container">$X=[x]_{R}$</span> and <span class="math-container">$Y=[x]_{R}$</span>, I know that if <span class="math-container">$f$</span> is a unit in <span class="math-container">$R$</span> then it is also in <span class="math-container">$R/(X)$</span> and <span class="math-container">$R/(Y^2)$</span>. Can this fact help me?</p>

which event fires if excel-vba modeless userform window gets focus back?. <p>I've got a modeless userform in an Excel VBA project.
The userform is loaded by button on spreadsheet clicked (<em>not</em> an active-x button if that's relevant).
Because of modeless the user can work with excel or even other applications and than switch back to the form window. <strong>I need an event that fires if the form window becomes the active window again.</strong> I thought <code>UserForm_Activate</code> should do the job but it doesn't (neither does <code>UserForm_GotFocus</code> but there is no GotFocus event for userforms?). Is there any event that fires if the user switches back to a modeless userform (or in case not: is there any known work-around)? Or do I've got some strange bug here and <code>Activate</code> should fire?</p>
<p>Here's all the code I used for testing purpose:</p>
<pre><code>' standard module:
Sub BUTTON_FormLoad()
' associated as macro triggered by button click on a sheet
UserForm1.Show vbModeless
End Sub
' UserForm1:
Private Sub UserForm_Activate()
' does not fire if focus comes back
Debug.Print "Activated"
End Sub
Private Sub UserForm_GotFocus()
' does not fire if focus comes back
' wrong code - no GotFocus event for userforms?
Debug.Print "Focussed"
End Sub
Private Sub UserForm_Click()
' only fires if clicked *inside* form
' does not fire eg if user clicks top of form window
Debug.Print "Clicked"
End Sub
</code></pre>
<p>Where do I find the documentation of userform events? It's not on the '<a href="https://docs.microsoft.com/de-de/office/vba/language/reference/user-interface-help/userform-object" rel="nofollow noreferrer">UserForm object</a>' page.</p>

How to use spot instance with amazon elastic beanstalk?. <p>I have one infra that use amazon elastic beanstalk to deploy my application.
I need to scale my app adding some spot instances that EB do not support.</p>
<p>So I create a second autoscaling from a launch configuration with spot instances.
The autoscaling use the same load balancer created by beanstalk.</p>
<p>To up instances with the last version of my app, I copy the user data from the original launch configuration (created with beanstalk) to the launch configuration with spot instances (created by me).</p>
<p>This work fine, but:</p>
<ol>
<li><p>how to update spot instances that have come up from the second autoscaling when the beanstalk update instances managed by him with a new version of the app?</p>
</li>
<li><p>is there another way so easy as, and elegant, to use spot instances and enjoy the benefits of beanstalk?</p>
</li>

Simple rsync incremental backup that timestamps deleted files. <p>I use <code>rsync</code> as follows:</p>
<blockquote>
<p>rsync -a --backup --suffix="."$(date +"%Y%m%d%H%M") <em>source backups</em></p>
</blockquote>
<p>to dump the whole of folder <em>source</em> into the folder <em>backups</em>, with the additional feature that if I modify some file <em>foo</em> in <em>source</em>, the old version of <em>foo</em> in backups will be renamed with a date suffix before the new <em>foo</em> is copied into <em>backups</em>.</p>
<p>This simple procedure does the job for me, only that I would like a <strong>deleted</strong> file to be <strong>renamed</strong> with the date suffix instead of being removed from <em>backups</em>. That is, if <em>foo</em> is deleted from source, then rename <em>foo</em> in <em>backups</em> with the date suffix.</p>

I also write movies and graphic novels. For fun, I like to sketch with a pen on actual paper. Ask me anything!

Reddit, I need some proposal ideas. I got nothing.. I've been racking my brain for weeks trying to think of a good way to propose to my girlfriend, and nothing I've come up with is good enough. I was hoping you guys could help me out.
Background info:
Me- 22 years old, slightly nerdy computer programmer/gamer.
Her- 22 years old, dancer, photography enthusiast, sweet tooth haver, reddit user (which is why I'm using a throw away account).
Situation- She's out of town right now, but she'll be coming back in a few weeks, and we are going to celebrate our 3 year anniversary. I want to take her to a nice dinner, and there is a dance performance that she wants to go to.
Also, I'm pretty sure that she doesn't want the proposal to be a public thing, so I don't think it's a good idea to actually do it at dinner or at the performance.

<li><p>Downloaded Ubuntu 18.04.4 amd64 on Desktop and driver DVD from <a href="https://ubuntu.com/download/desktop" rel="nofollow noreferrer">https://ubuntu.com/download/desktop</a></p></li>
<li><p>Tried manually to make the stick bootable through found description. Tried with Rufus-download but Rufus on my PC does not display the option to have Ubuntu 18.04.4 amd64 as Start. Rufus display several options as Start (translated from german): - "no start ability", - "Free DOS" and several other options.</p></li>
</ul>
<p>When just copied Ubuntu on the stick, trying through Bios nothing could been found to start the PC through USB device.</p>
<p>No description which I tried works, it's frustrating!</p>
