\section{Introduction}
\label{Introduction}

The Muon $g$-2 (E989) experiment at Fermilab has recently presented their first measurement of the muon magnetic moment anomaly, $a_{\mu} = (g-2)/2$~\cite{Muong-2:2021ojo,Muong-2:2021vma,Muong-2:2021ovs,Muong-2:2021xzz}, confirming the earlier results of the E821 experiment at Brookhaven~\cite{Muong-2:2006rrc}. The E989 experiment is expected to reach a sensitivity four-times better than the E821 one. In addition, a new low-energy approach to measuring the muon $g$-2 is being developed by the E34 collaboration at J-PARC~\cite{Abe:2019thb}.

The present muon $g$-2 experimental average shows an intriguing $4.2 \sigma$ discrepancy with the value for the Standard Model (SM) $a_{\mu}$ prediction quoted by the Muon $g$-2 Theory Initiative~\cite{Aoyama:2020ynm}. If confirmed with high significance, this discrepancy would be indirect evidence for new physics beyond the SM.

The main uncertainty of the muon $g$-2 SM prediction origins from its hadronic vacuum polarization (HVP) contribution, $a_{\mu}^{\rm HVP}$, which cannot be reliably calculated perturbatively in QCD and relies on experimental data as input to dispersion relations. Indeed, this contribution has been traditionally computed via a dispersive, or time-like, integral using hadronic production cross sections in low-energy electron-positron annihilation~\cite{Jegerlehner:2017gek,Colangelo:2018mtw,Hoferichter:2019mqg,Davier:2019can,Keshavarzi:2019abf,Kurz:2014wya}.

An alternative determination of $a_{\mu}^{\rm HVP}$ can be provided by lattice QCD. Significant progress has been made in the last few years in first-principles calculations of its leading order (LO) part, $a_{\mu}^{\rm HVP}({\rm LO})$, although these results are, in general, not yet competitive with the time-like determinations based on experimental data. Recently, the BMW collaboration presented the first lattice QCD determination of $a_{\mu}^{\rm HVP}({\rm LO})$ with an impressive sub-percent (0.8\%) relative accuracy~\cite{Borsanyi:2020mff}. This remarkable result weakens the long-standing discrepancy between the SM muon $g$-2 prediction and the experimentally measured value. However, this result shows tension with the time-like data-driven determinations of $a_{\mu}^{\rm HVP}({\rm LO})$, being $2.2 \sigma$ higher than the Muon $g$-2 Theory Initiative data-driven value. Moreover, shifts up of the $e^+ e^- \to $ hadrons cross section, due to unforeseen missing contributions, to increase $a_{\mu}^{\rm HVP}({\rm LO})$ and solve the present muon $g$-2 discrepancy, lead to conflicts with the global electroweak fit if they occur at energies higher than $\sim 1$~GeV (and below that energy they are deemed improbable given the large required increases in the hadronic cross section)~\cite{Passera:2008jk,Keshavarzi:2020bfy,Crivellin:2020zul,Malaescu:2020zuc,Colangelo:2020lcg}. A new and competitive determination of the HVP contribution to the muon $g$-2, based on a method alternative to the time-like and lattice QCD ones, is therefore desirable.

A novel approach to determine the leading hadronic contribution to the muon $g$-2, measuring the effective electromagnetic coupling in the space-like region via scattering data, was proposed a few years ago~\cite{CarloniCalame:2015obs}. The elastic scattering of high-energy muons on atomic electrons has been identified as an ideal process for this measurement, and a new experiment, MUonE, has been proposed at CERN to measure the shape of the differential cross section of muon-electron elastic scattering as a function of the space-like squared momentum transfer~\cite{Abbiendi:2016xup,MUonE:LoI,Banerjee:2020tdt}.

In this paper we investigate the HVP contributions to the muon $g$-2 in the space-like region. At LO, simple results are long known and form the basis for the present lattice QCD and future MUonE determinations of $a_{\mu}^{\rm HVP}({\rm LO})$. Our goal is to provide simple exact analytic expressions to extend the space-like calculation of the $a_{\mu}^{\rm HVP}$ contribution to next-to-leading order (NLO).

\section{The HVP contribution at leading order}
\label{HVPLO}

\subsection{Time-like method}

Consider the hadronic component of the vacuum polarization tensor with four-momentum $q$,
\begin{align}
  i \Pi_{\rm h}^{\mu\nu}(q) &= i \Pi_{\rm h}(q^2) \left(g^{\mu\nu}q^2-q^\mu q^\nu \right)  \notag \\
                             &=  \int {\rm d}^4 x \,\, e^{iqx} \langle 0 | T \left\{j^\mu_{\rm em}(x) j^\nu_{\rm em} (0) \right\} | 0 \rangle,
\end{align}
where $j^\mu_{\rm em}(x)$ is the electromagnetic hadronic current and $\Pi_{\rm h}(q^2)$ is the renormalized hadronic vacuum polarization function satisfying the condition $\Pi_{\rm h}(0) = 0$. The function $\Pi_{\rm h}(q^2)$ cannot be calculated in perturbation theory because of the non-perturbative nature of the strong interactions at low energy. Yet, the optical theorem ${\rm Im} \Pi_{\rm h}(s) = (\alpha/3) R(s)$, where the $R$-ratio is
\begin{align}
  R(s) = \frac{\sigma(e^+e^- \to \text{hadrons})}{4\pi \alpha^2/(3 s)}
\end{align}
and $\alpha$ is the fine-structure constant, allows to express the imaginary part of the hadronic vacuum polarization in terms of the measured cross section of the process $e^+ e^- \to $ hadrons as a function of the positive squared four-momentum transfer $s$. This result forms the basis for the time-like method.

The leading-order hadronic contribution to the muon $g$-2 can be calculated integrating experimental time-like (i.e.\ $q^2>0$) data using the well-known formula~\cite{Bouchiat:1961lbg,Brodsky:1967sr,Lautrup:1968tdb}
\begin{equation}
	a_{\mu}^{\rm HVP}({\rm LO}) = \frac{\alpha}{\pi^2} \int_{s_0}^{\infty} \frac{{\rm d}s}{s}
	\;K^{(2)}(s/m^2)\; {\rm Im} \Pi_{\rm h} (s),
\label{eq:amuHLOtime}
\end{equation}
where $m$ is the muon mass and $s_0=m^2_{\pi^0}$. Defining
\begin{equation}
	z = \frac{q^2}{m^2}
	\label{eq:z}
\end{equation}
and the rationalizing variable
\begin{equation}
	y(z) = \frac{\sqrt{z} - \sqrt{z-4}}{\sqrt{z} + \sqrt{z-4}},
\label{eq:y}
\end{equation}
the second-order function $K^{(2)}(z)$ for $z \geq 0$ is
\begin{align}
	K^{(2)}(z) &= \frac{1}{2} -z + \left( \frac{z^2}{2} -z \right) \ln z \nonumber \\
	&+ \frac{\ln y(z)}{\sqrt{z(z-4)}} \left( z -2 z^2 + \frac{z^3}{2}\right).
\label{eq:K2}
\end{align}
For $z \geq 0$, $K^{(2)}(z)$ is real, positive and monotonic. At $z=0$, $K^{(2)}(0)=1/2$, while for $z \to +\infty$ the asymptotic behaviour of the kernel function is $K^{(2)}(z) \to 1/(3z)$, therefore vanishing at infinity.

\subsection{Space-like method}

The time-like expression for $a_{\mu}^{\rm HVP}({\rm LO})$ provided by~\eq{amuHLOtime} can be rewritten using the dispersion relation satisfied by $K^{(2)}(z)$~\cite{Barbieri:1974nc},
\begin{equation}
	K^{(2)} (z) = \frac{1}{\pi} \int_{-\infty}^0 \! {\rm d}z'\, \frac{{\rm Im} K^{(2)} (z')}{z'-z}, \quad z>0.
\label{eq:DRK2t}
\end{equation}
Indeed, replacing $K^{(2)}(s/m^2)$ in~\eq{amuHLOtime} with~\eq{DRK2t} and integrating over $s$ via the subtracted dispersion relation satisfied by $\Pi_{\rm h}(q^2)$,
\begin{equation}
	\frac{\Pi_{\rm h}(q^2)}{q^2} =  \frac{1}{\pi}  \int_{s_0}^{\infty}  \frac{{\rm d}s}{s} \frac{{\rm Im} \Pi_{\rm h}(s)}{s-q^2}, \quad q^2<0,
\label{eq:DRPi}
\end{equation}
we obtain the space-like expression
\begin{equation}
	a_{\mu}^{\rm HVP}({\rm LO}) = - \frac{\alpha}{\pi^2} \int_{-\infty}^{0} \frac{{\rm d}t}{t} \,  \Pi_{\rm h}(t) \, {\rm Im} K^{(2)}(t/m^2).
\label{eq:amuHLOspace}
\end{equation}

The function $K^{(2)}(z)$, real for any $z \geq 0$, has a cut along the negative real axis $z<0$ with the imaginary part
\begin{align}
{\rm Im} K^{(2)} (z + i \epsilon) &= \pi \, \theta(-z) \! \left[  \frac{z^2}{2} -z  + \frac{z -2 z^2 + z^3/2}{\sqrt{z(z-4)}}\right] \nonumber \\
						&= \pi \, \theta(-z) \, F^{(2)} (y(z)),
\label{eq:ImK2}
\end{align}
where
\begin{equation}
	F^{(2)} (y)  = \frac{y+1}{y-1} \, y^2.
\label{eq:F2}
\end{equation}
The $i \epsilon$ prescription, with $\epsilon>0$, indicates that, in correspondence of the cut, the function Im$K^{(2)}(z)$ is evaluated approaching the real axis from above. Equation~(\ref{eq:ImK2}) can be immediately derived from the analytic continuation of $K^{(2)}(z)$ for $z<0$, which can be obtained from~\eq{K2} replacing $y(z)$, for $z>0$, with $1/y(z)$, for $z<0$.

If in~\eq{amuHLOspace} one uses the explicit expression for ${\rm Im} K^{(2)}\!(t/m^2)$ of~\eq{ImK2} and changes the integration variable from $t$ to $x=1+y$ via the substitution
\begin{equation}
	t(x) = \frac{m^2 x^2}{x-1},
\label{eq:tofx}
\end{equation}
obtained from \eq{y}, one finds~\cite{Lautrup:1971jf}
\begin{equation}
	a_{\mu}^{\rm HVP}({\rm LO}) = \frac{\alpha}{\pi} \int_{0}^{1} {\rm d}x \, \kappa^{(2)} (x) \, \Delta \alpha_{\rm h}( t(x) ),
\label{eq:amuHLOspacex}
\end{equation}
where the space-like kernel is remarkably simple,
\begin{equation}
	\kappa^{(2)} (x) = 1-x
\label{eq:kappa2}
\end{equation}
and $\Delta \alpha_{\rm h} (t)= -\Pi_{\rm h}(t)$ is the (five-flavor) hadronic contribution to the running of the effective fine-structure constant in the space-like region.

Equation~(\ref{eq:amuHLOspacex}) (or forms equivalent to it) is used in lattice QCD calculations of $a_{\mu}^{\rm HVP}({\rm LO})$ (see e.g.\ \cite{Blum:2002ii} and a discussion in~\cite{Aoyama:2020ynm}). It also forms the basis for the MUonE proposal to determine $a_{\mu}^{\rm HVP}({\rm LO})$ via muon-electron scattering data~\cite{CarloniCalame:2015obs,Abbiendi:2016xup,MUonE:LoI,Banerjee:2020tdt}.

\section{The HVP contribution at NLO}
\label{HVPNLO}

The hadronic vacuum polarization contribution to the muon $g$-2 at next-to-leading order, $a_{\mu}^{\rm HVP}({\rm NLO})$, is due to three classes of diagrams of order $\mathcal{O}(\alpha^3)$, see Fig.~\ref{fig:LONLOdiagrams}.
\begin{figure}
\begin{center}
\includegraphics[width=\columnwidth]{fig1.pdf}
\caption{LO and sample NLO diagrams contributing to the HVP contribution to the muon $g$-2.}
\label{fig:LONLOdiagrams}
\end{center}
\end{figure}
Class $(a)$ consists of diagrams with one single HVP insertion in one of the photon lines of the two-loop QED diagrams contributing to the muon $g$-2, without any vacuum polarization insertion due to electron or tau loops. Class $(b)$ contains diagrams with one HVP and one additional vacuum polarization due to an electron or tau loop. Finally, class $(c)$ consists of the diagram with two HVPs. Numerically, class $(a)$ yields the largest (negative) contribution, class $(b)$ partially cancels it, and the contribution of class $(c)$ is very small, as expected. These contributions will be called $a_{\mu}^{(a)}$, $a_{\mu}^{(b)}$ and $a_{\mu}^{(c)}$, respectively, with
\begin{equation}
	a_{\mu}^{\rm HVP}({\rm NLO}) = a_{\mu}^{(a)} + a_{\mu}^{(b)} + a_{\mu}^{(c)}.
\label{eq:amuHVPNLO}
\end{equation}

\subsection{Class $(a)$}
\label{HVPNLOa}

The NLO HVP contribution of class $(a)$ to the muon $g$-2 can be written in the time-like form~\cite{Barbieri:1974nc}
\begin{equation}
	a_{\mu}^{(a)} =  \frac{\alpha^2}{\pi^3} \int_{s_0}^{\infty} \frac{{\rm d}s}{s} \, 2K^{(4)}(s/m^2)\, {\rm Im} \Pi_{\rm h} (s).
\label{eq:amuAtime}
\end{equation}
The fourth-order function $K^{(4)}(z)$ was first computed by Barbieri and Remiddi in~\cite{Barbieri:1974nc}.\footnote{Note the coefficient 2 in front of the function $K^{(4)}(z)$ due to the original normalization chosen in Ref.~\cite{Barbieri:1974nc}.} Its lengthy expression is reported in their Eq.~(3.21) for $z>0$, where it is real and negative. An approximate series expansion for $K^{(4)}(s/m^2)$ in the parameter $m^2/s$, with terms up to fourth order, can be found in~\cite{Krause:1996rf}.

Like $K^{(2)}(z)$, the function $K^{(4)}(z)$ is real for any $z \geq 0$, has a cut for $z<0$, and satisfies the dispersion relation
\begin{equation}
	K^{(4)} (z) = \frac{1}{\pi} \int_{-\infty}^0 \! {\rm d}z'\, \frac{{\rm Im} K^{(4)} (z')}{z'-z}, \quad z>0.
\label{eq:DRK4t}
\end{equation}
Just as we did for $a_{\mu}^{\rm HVP}({\rm LO})$, using the dispersion relations~(\ref{eq:DRPi}) and (\ref{eq:DRK4t}) the NLO hadronic contribution of class $(a)$ can be cast in the space-like form
\begin{equation}
	a_{\mu}^{(a)} = - \frac{\alpha^2}{\pi^3} \int_{-\infty}^{0} \frac{{\rm d}t}{t} \,  \Pi_{\rm h}(t) \, 2{\rm Im} K^{(4)}(t/m^2).
\label{eq:amuAspace}
\end{equation}

To compute ${\rm Im} K^{(4)}(t/m^2)$, first we analytically continue the $K^{(4)}(z)$ expression of Ref.~\cite{Barbieri:1974nc} from $z>0$ to $z<0$, replacing $y(z)$ with $1/y(z)$ in order to choose coherently the Riemann sheets on the cut. Then, taking the imaginary parts of the resulting polylogarithms (of order 1, 2, and 3), we obtain\footnote{After presenting our ${\rm Im}  K^{(4)} (z)$ result, Eqs.(\ref{eq:ImK4}--\ref{eq:R15}), in~\cite{Laporta:Strong2021} (see also~\cite{Passera:Remiddi2021}), we were informed by Alexander Nesterenko that he has independently derived it in~\cite{Nesterenko:2021byp}.}
\begin{equation}
	{\rm Im}  K^{(4)} (z + i \epsilon) = \pi \, \theta(-z) \, F^{(4)} (y(z)),
\label{eq:ImK4}
\end{equation}
where
\begin{align}
	F^{(4)} (y)    & = R_1(y) + R_2(y) \ln (-y) \nonumber \\
	          & \,+ R_3(y) \ln (1+y) + R_4(y) \ln (1-y) \nonumber \\
	          & \,+ R_5(y)\big[ 4{\rm Li}_2(y) + 2{\rm Li}_2(-y)   \nonumber \\
	&~~~~+\ln(-y) \ln \! \left( (1-y)^2  (1+y)  \right) \! \big],
\label{eq:F}
\end{align}
and the rational functions $R_i(y)$ $(i=1,\ldots,5)$ are
\begin{align}
	R_1 \!= &  \frac{23 y^6 \!-\! 37 y^5 \!+\! 124 y^4 \!-\! 86 y^3 \!-\! 57 y^2 \!+\! 99 y \!+\! 78}{72 (y-1)^2 y (y+1)}, \nonumber \\
	R_2 \!= &  \frac{12 y^8 \!-\! 11 y^7 \!-\! 78 y^6 \!+\! 21 y^5 \!+\! 4 y^4 \!-\! 15 y^3 \!+\! 13 y \!+\! 6}{12 (y-1)^3 y (y+1)^2},  \nonumber \\
	R_3 \!= &  \frac{(y+1) \left(-y^3 + 7 y^2 + 8 y + 6\right)}{12 y^2}, \nonumber \\
	R_4 \!= &  \frac{-7 y^4 - 8 y^3 + 8 y + 7}{12 y^2}, \nonumber \\
	R_5 \!= & -\frac{3 y^4 + 5 y^3 + 7 y^2 + 5 y + 3}{6 y^2}.
\label{eq:R15}
\end{align}
The dilogarithm is ${\rm Li}_2(y) = -\int_{0}^y ({\rm d}u/u) \ln (1-u)$.

Using the explicit expression for ${\rm Im} K^{(4)}\!(t/m^2)$ of~\eq{ImK4},~\eq{amuAspace} can be conveniently expressed in terms of the variable $x=1+y$. We obtain
\begin{equation}
	a_{\mu}^{(a)}  =  \left( \frac{\alpha}{\pi} \right)^2 \! \int_{0}^{1} {\rm d}x \, \kappa^{(4)} (x) \, \Delta \alpha_{\rm h}( t(x) ),
\label{eq:amuAspacex}
\end{equation}
where
\begin{equation}
	\kappa^{(4)} (x) = \frac{2-x}{x\left(x-1\right)} \, 2F^{(4)} (x-1).
\label{eq:kappa4}
\end{equation}
For $0 \leq x < 1$, $z \leq 0$. Equation~(\ref{eq:amuAspacex}) is the analogue of~\eq{amuHLOspacex} for the NLO contribution of class $(a)$.
\begin{figure}
\begin{center}
\includegraphics[width=\columnwidth]{fig2.pdf}
\caption{The space-like functions $\kappa^{(2)} (x)$ (blue), $\kappa^{(4)} (x)$ (orange) and $\tilde{\kappa}^{(4)} (x)$ (green).}
\label{fig:kappa24tilde}
\end{center}
\end{figure}
Figure~\ref{fig:kappa24tilde} shows the space-like functions $\kappa^{(2)} (x)$ and $\kappa^{(4)} (x)$ entering the $a_{\mu}^{\rm HVP}({\rm LO})$ and $a_{\mu}^{(a)}$ expressions, respectively. We note that the function $\kappa^{(4)} (x)$ provides a stronger weight to $\Delta \alpha_{\rm h}(q^2)$ at large negative values of $q^2$ than $\kappa^{(2)} (x)$. In particular, for $q^2 \to -\infty$, $\kappa^{(2)} (1) =0$, whereas $\kappa^{(4)} (1) = -23/18$.
Figure~\ref{fig:integrand24} shows the LO integrand $(\alpha/\pi) \kappa^{(2)} (x) \Delta \alpha_{\rm h}(t(x))$ of~\eq{amuHLOspacex} and the NLO integrand $(\alpha/\pi)^2 \kappa^{(4)} (x) \Delta \alpha_{\rm h}(t(x))$ of~\eq{amuAspacex}, multiplied by $10^7$ and $-10^8$, respectively. The LO integrand has a peak at $x \sim 0.914$, where $t \sim -(0.33 {\rm GeV})^2$. On the other hand, the NLO integrand of class $(a)$ increases monotonically with $x \to 1$ (i.e.\ with $t \to -\infty$) like $\sim \ln (1-x)$.
\begin{figure}
\begin{center}
\includegraphics[width=\columnwidth]{fig3.pdf}
\caption{The integrands $(\alpha/\pi) \kappa^{(2)} (x) \Delta \alpha_{\rm h}(t(x))$ (blue) and $(\alpha/\pi)^2 \kappa^{(4)} (x) \Delta \alpha_{\rm h}(t(x))$ (orange) of Eqs.(\ref{eq:amuHLOspacex}) and (\ref{eq:amuAspacex}), multiplied by $10^7$ and $-10^8$, respectively.}
\label{fig:integrand24}
\end{center}
\end{figure}

An approximate expression for the space-like formula in~\eq{amuAspacex} was provided in Ref.~\cite{Chakraborty:2018iyb}. To obtain it, the authors started considering the approximate fourth-order series expansion of Ref.~\cite{Krause:1996rf} for the time-like function $K^{(4)}(s/m^2)$ in the small parameter $r=m^2/s$. This series expansion only contains powers $r^n$ of degree $n=1,2,3,4$, multiplied by constants, $\ln r$, and $(\ln r)^2$ terms. Then, as suggested in~\cite{Groote:2001vu}, they exploited generating integral representations to fit the $r^n$ and $r^n \! \ln r$ terms of the approximate fourth-order series expansion for $K^{(4)}(1/r)$, but not the $r^n (\ln r)^2$ ones, and used the usual dispersion relation satisfied by $\Pi_{\rm h}(q^2)$ to perform the integral over $s$. After some simple changes of variables, their approximation can be compared with our exact function $\kappa^{(4)} (x)$. We repeated the analysis of Ref.~\cite{Chakraborty:2018iyb} confirming their approximate result (in particular, their Eqs.~(A1,A2)) which, translated in our notation, will be called here $\tilde{\kappa}^{(4)} (x)$.

The approximate function $\tilde{\kappa}^{(4)} (x)$ is plotted in Fig.~\ref{fig:kappa24tilde} (indicated by the green line). While the exact function $\kappa^{(4)} (x)$ varies smoothly over the entire region $0 \leq x \leq 1$, $\tilde{\kappa}^{(4)} (x)$ strongly oscillates, leading to large numerical cancelations when employed in the integral of~\eq{amuAspacex} instead of $\kappa^{(4)} (x)$. Using the Fortran libraries KNT18VP~\cite{Harlander:2002ur,Hagiwara:2003da,Hagiwara:2006jt,WorkingGrouponRadiativeCorrections:2010bjp,Hagiwara:2011af,Keshavarzi:2018mgv} for the numerical implementation of $\Delta \alpha_{\rm h}(t(x))$ in the space-like region, we computed two numerical values for $a_{\mu}^{(a)}$ in~\eq{amuAspacex}: one obtained using the exact function $\kappa^{(4)} (x)$ and a second one obtained replacing $\kappa^{(4)} (x)$ with the approximate $\tilde{\kappa}^{(4)} (x)$. The two values differ by about 3\%. Adding to $a_{\mu}^{(a)}$ the contributions $a_{\mu}^{(b)}$ and $a_{\mu}^{(c)}$ (discussed later), the total $a_{\mu}^{\rm HVP}({\rm NLO})$ contribution computed using the $\tilde{\kappa}^{(4)} (x)$ approximation differs from the one computed via our exact function $\kappa^{(4)} (x)$ by about 6\%.

It is interesting to investigate the source of the above $\sim 6$\% discrepancy. To improve the $\tilde{\kappa}^{(4)} (x)$ approximation, we proceeded in two directions. The first one consisted in repeating the analysis of Ref.~\cite{Chakraborty:2018iyb}, starting however from higher-order series expansions for the exact $K^{(4)}(s/m^2)$ function of Barbieri and Remiddi~\cite{Barbieri:1974nc} (we considered $n$ up to $n_{\rm max}=24$), rather than from the fourth-order (i.e.\ $n_{\rm max}=4$) series expansion for $K^{(4)}(s/m^2)$ of Ref.~\cite{Krause:1996rf}. Our second improvement consisted in exploiting generating integral representations to fit the $r^n$, $r^n \! \ln r$, as well as the $r^n (\ln r)^2$ terms which were omitted in the analysis of Ref.~\cite{Chakraborty:2018iyb}. Our studies show that the inclusion of the $r^n (\ln r)^2$ terms greatly improves the $\kappa^{(4)} (x)$ approximations, even if the order $n_{\rm max}$ of the series expansion for $K^{(4)}(s/m^2)$ is not increased above four. Calling $\bar{\kappa}^{(4)} (x,n_{\rm max})$ our improved approximation for $\kappa^{(4)} (x)$ obtained including $r^n (\ln r)^2$ terms starting from the series expansion for $K^{(4)}(s/m^2)$ up to order $n_{\rm max}$, we verified that the total $a_{\mu}^{\rm HVP}({\rm NLO})$ contribution computed using our $\bar{\kappa}^{(4)} (x,4)$ differs by less than one per mille from the one computed via our exact function $\kappa^{(4)} (x)$. Even better agreements were reached increasing the order $n_{\rm max}$.

The authors of Ref.~\cite{Chakraborty:2018iyb} added an $O(10\%)$ uncertainty to their final result to take into account the error induced by the omission of the $r^n (\ln r)^2$ terms. This uncertainty, which dominates the error of their final result, can be eliminated using the simple formula for $\kappa^{(4)} (x)$ provided in this paper.

\subsection{Classes $(b)$ and $(c)$}
\label{HVPNLObc}

The space-like expressions for the class $(b)$ and $(c)$ NLO HVP contributions to the muon $g$-2 are~\cite{Chakraborty:2018iyb}

\begin{align}
	a_{\mu}^{(b)} &=  \frac{\alpha}{\pi} \int_{0}^{1} {\rm d}x \, \kappa^{(2)} (x) \, \Delta \alpha_{\rm h}( t(x) )
	\label{eq:amuBspacex} \nonumber \\
	                      & ~~~~~~~ \times 2 \left[ \Delta \alpha_e^{(2)}( t(x) )  + \Delta \alpha_{\rm \tau}^{(2)}( t(x) ) \right], \\
	a_{\mu}^{(c)} & =  \frac{\alpha}{\pi} \int_{0}^{1} {\rm d}x \, \kappa^{(2)} (x) \, \left[ \Delta \alpha_{\rm h}( t(x) ) \right]^2,
\label{eq:amuCspacex}
\end{align}
where $\Pi_{\ell}^{(2)} (t) = -\Delta \alpha_{\ell}^{(2)}(t)$ is the renormalized one-loop QED vacuum polarization function in the space-like region, with a lepton $\ell=e,\tau$ in the loop,
\begin{equation}
	\Pi_{\ell}^{(2)} (t) = \frac{\alpha}{\pi}  \left[
					\frac{8}{9}  - \frac{\beta_{\ell}^2}{3}  + \beta_{\ell} \! \left(\frac{1}{2} - \frac{\beta^2_{\ell}}{6} \right) \! \ln \frac{\beta_{\ell}-1}{\beta_{\ell}
					 +1} \right]
\end{equation}
and $\beta_{\ell}= \sqrt{1-4m_\ell^2/t}$. Equations (\ref{eq:amuBspacex},\ref{eq:amuCspacex}) can be immediately obtained from the time-like formulae of Ref.~\cite{Krause:1996rf} using the usual dispersion relation satisfied by $\Pi_{\rm h}(t)$ and $\Pi_{\ell}^{(2)} (t)$ to perform the integrals over $s$~\cite{Lautrup:1971jf,Chakraborty:2018iyb}.

\section{Conclusions}
\label{Conclusions}

In this paper we provided simple exact analytic expressions to extend the computation of the hadronic vacuum polarization contribution to the muon $g$-2 in the space-like region up to next-to-leading order. These results can be employed to determine very precisely $a_{\mu}^{\rm HVP}({\rm NLO})$, which is due to three classes of diagrams of order $\mathcal{O}(\alpha^3)$, via lattice QCD as well as scattering data like those expected of the proposed MUonE experiment at CERN. In fact, it would be very interesting to compute precisely, besides $a_{\mu}^{\rm HVP}({\rm LO})$, also the $a_{\mu}^{\rm HVP}({\rm NLO})$ term on the lattice. This would provide consistent and precise NLO comparisons of the HVP contribution to the muon $g$-2 computed via lattice QCD with results already obtained via time-like data.

Existing approximations for the NLO function $\kappa^{(4)} (x)$ induced the largest source of uncertainty in the NLO lattice QCD calculation of Ref.~\cite{Chakraborty:2018iyb}. This uncertainty, of $O(10\%)$, can be eliminated using the exact expression for $\kappa^{(4)} (x)$ provided in this paper.

Finally, the NLO weight functions of the $a_{\mu}^{\rm HVP}({\rm NLO})$ contributions were found to differ significantly from the LO one of $a_{\mu}^{\rm HVP}({\rm LO})$. In particular, the function $\kappa^{(4)} (x)$ provides a stronger weight to $\Delta \alpha_{\rm h}(q^2)$ at large negative values of $q^2$ than $\kappa^{(2)} (x)$. These different weights may help shed light on the tension between the lattice BMW determination of the LO HVP contribution to the muon $g$-2 and those obtained with time-like data.

FORT MYERS, Fla. – The FGCU men's soccer team unveiled its new uniform from INARIA – an alternate, all-green third kit – for the 2016 season Wednesday night at Eagle Revolution.
For the 2016 season, the team designed a kit that's completely its own as a translucent sublimated Eagle is subtly displayed across the University's signature green color.
The jersey can be paired with either the royal blue or white short, giving the team more possible uniform combinations and full flexibility when it comes to choosing its look on match day.
Earlier this week, the Eagles were installed as the preseason Atlantic Sun Conference favorites to win the league for a record seventh-straight year. Additionally, a trio of Eagles were named to the Preseason ASUN All-Conference Team: Nicolas Samayoa, Miguel Jaime and Albert Ruiz, with Samayoa being selected as the Preseason Defensive Player of the Year and Ruiz being the only unanimous selection to the 14-player team.
INARIA incorporates leading technologies into its apparel to help maximize the athlete's performance and comfort, including 37.5 technology. Fabrics designed with 37.5 technology dry up to five times faster than similar materials, and the Eagles will be wearing 37.5 technology for the first time this season.
INARIA has extensive uniform partnerships with professional players and clubs, including Toronto F.C.'s Sebastian Giovinco, who won the 2015 Landon Donovan MLS MVP Award, and a roster of D-I teams and elite amateur programs.
The 2016 season gets underway for the Eagles at Northwestern on Friday, Aug. 26, before returning for their home opener against Michigan on Monday, Aug. 29, at 7 p.m. The slate features 11 non-league matchups, eight home contests (all scheduled for 7 p.m. starts) and nine road competitions. Four opponents made 2015 NCAA Tournament appearances and four accumulated double-figure wins last season.
Season and single-game tickets are now available for the 2016 campaign, with season tickets starting at just $35. More information, including special discounts and group rates, can be accessed by visiting FGCUTickets.com. To purchase tickets, or for additional inquiries, call the FGCU Ticket Office at 239-590-7145 Monday-Friday from 9 a.m.-5 p.m.


City of Lights, of course, but even more so, Paris is a city of life, and Francoise Paviot celebrates that happy fact with this collection of Parisian photographs that takes us from the medium's early days and into the 1990s. The images are all black-and-white, some are iconic (Eugene Atget's "Organ Grinder," for instance), and the unifying theme is the great city's embrace of scale, spectacle, and always, the local color of its people.
In her text (in French), gallery owner and collector Paviot notes that Paris is the official birthplace of photography, and indeed, from the first daguerreotypes, it has been one of the medium's great subjects--arguably its greatest. It would be hard to imagine any icon that has been more photographed than the Eiffel Tower, but Paviot does not drown us with Tower photos, preferring instead to connect the human with the monumental, as in the charming cover shot of stylish 1920s louche youth hanging out, smoking and preening high upon the Tower (during the making of Rene Clair's 1927 film, "Paris qui dort"), as well as a more formal shot by Pierre Petit of dignitaries assembled at the Tower's 1889 inauguration. And André Kertész's 1927 shot of the Tower illuminated by bolts of lightning is, of course, incomparable.
Indeed, Parisian architecture is central to these shots, beginning with an 1844 image by Charles-Marie Isodore of riders on horseback on the Pont Royal, in full view of a magnificent mansard-roofed dwelling. Other 19th-century images capture the splendor of La Place de la Concorde, the grand boulevards, fountains, arches, and the Seine, including a wonderful rooftop perspective along the Boulevard des Capucines, by William Henry Fox Talbot. Chronicling the wonders of the Second Empire, Paviot finds images of the great Parisian boom in urban development, along with parades, gatherings, and the sights of the Universal Exposition of 1867.
These historical photos are at once charming and broad, mainly long views that capture scale at the expense of intimate detail, as in an important documentary shot of Victor Hugo's massive funeral on the steps of the Pantheon. As the 20th century begins, along with France's Third Empire, photography's refinement is evident in the works not only of Atget, but of Emile Joachim Constant Puyo, whose wonderful image of a chambermaid peering over a balcony in Montmartre--with Sacre Coeur mistily off in the distance--is a 1906 masterwork.
There is also a photo by Emile Zola of a pavilion at the universal exposition of 1900, and images of Parisians at galleries, peering through telescopes, observing a solar eclipse through smoked glass, and a panoramic shot by Jacques-Henri Lartigue of his model Bibi at the 1927 international exposition of decorative and industrial arts. Indeed, to celebrate Paris is to celebrate its artists, and there is a fine still from Rene Clair's 1924 film "Entracte", featuring Marcel Duchamp and Man Ray playing chess, as well as an anonymous image depicting surrealist founder Andre Breton playfully holding a friend upside down from atop a ladder with a bicycle in front of a gallery showing paintings by Max Ernst.
Moving into the pre- and post-World War II eras, the photographs capture the intensity of modernity, with its cars, crowds, and anxious faces, always with the timelessness of Paris as a backdrop. There is Robert Doisneau's memorable 1944 shot of jubilant young students in a marching band, and Christophe Gin's 1993 image of gay-pride marchers, their painted faces betraying a solemn sense of the outsider. And Wolfgang Volz's 1985 shot of the Pont Neuf wrapped in the vast shroudings of artist Christo brings us full circle--from a Paris of the Old World to a Paris that can more than accommodate the shock of the new.


Do your arguments tend to occur primarily after one of you has had several drinks? Have either of you had 2 DWI's? Have either of you expressed a need to cut down your drinking for other than dietary considerations? Do either of you frequently drink 4 or 5 drinks per evening? Do others ever complain about your drinking? Do either of you smoke cannabis (pot) on the average of two or more times per week? Have either of you experienced morning tremors (jitteriness) the morning after? Have either of you had gaps in your memory involving the period in which you were drinking?
If you think that either of you may have a substance abuse problem, it is best to first get professional help for the chemical dependence. Until the chemical dependence is arrested, attempts to focus on communication and emotional intimacy will usually be futile. It should also be mentioned that trying to confront a chemically dependent person without adequate preparation can be destructive or even dangerous. It is recommended that you consult with a chemical dependence specialist before trying such an intervention on your partner.
1) Set up an appointment with a counselor who has certification of proficiency for substance abuse counseling. Cary Counseling Center has several such professionals on staff (See Staff Profiles). Follow their guidance after they have met with you to assess your situation.
2) Telephone Alcoholics Anonymous or Narcotics Anonymous to find out the locations and schedule of meetings in your area. In the general Raleigh, North Carolina area, those numbers are (919) 783 6144 and (919) 755 5391 respectively. In other regions of the country, try using Google to get a number local to you.
3) If your are outside of the Raleigh area or if you desire good literature on recovery from chemical dependence, go to www.aa.org or www.na.org on the internet. There you can obtain telephone numbers of local AA and NA chapters where you can obtain meeting schedules.
It is important to note here that "cold-turkey" quitting of certain drugs or alcohol can be very dangerous in some circumstances. Be sure to consult with a professional about whether detoxification services will be needed.
1) Set up an appointment for you to meet with a certified substance abuse counselor. If you and your partner have not been comfortably communicating about the substance abuse, then it is best for you go to the appointment alone. You and your counselor can strategize about whether or not an intervention is feasible. You will also receive advise about how to minimize your own emotional damage from being in the relationship. If you and your partner can comfortably communicate about the substance abuse, then go to the appointment together.
2) Call Alanon and go to a meeting. In Raleigh, North Carolina the telephone number is (919) 713 1516. Attendance in this program will help you to keep a better emotional balance by practicing healthy detachment from your partner's illness. It can even have a subtle but powerful effect on other aspects of the relationship. However, the simplest and most obvious benefit is that it reduces your own level of shame. If you live outside the Raleigh area, you can go to www.al-anon-alateen.org on the internet. There you can get local chapter information as well as good literature references.


We ate an early dinner of leftovers from the week and then told Kye we had one last special birthday surprise for him! He was SO excited and was also super sweet and concerned about Britt's feelings being hurt since she would not be going with us. We decided to have Mrs. Charlotte stay back with Britt at the condo because the event was pretty late but also because we wanted it to be ALL about Kye. And two year olds have a way with monopolizing a lot of the attention 😉 I'm so, so glad we decided to have it just be the three of us. I felt pretty guilty about it when we first left b/c Britt had LOVED the fireworks during the week and she loved Captain Hook so I knew she really would have enjoyed it. But hopefully there will be another opportunity for her to go too!
Last time seeing this sign!
When I packed for the trip I wasn't sure IF Kye would want to dress in the theme for the event. And if he did want to, I wasn't sure if he'd want to wear his Peter Pan costume from Halloween or a pirate outfit. So I brought it all and when we told him what was happening we showed him his options and let him choose. He went with the pirate outfit he wore last May at Disney (Which, btw, I got for like $5 at a used kids sale and it's been a HUGE hit. In fact, it's now too small and I totally need to get him a new one! We didn't even have a pirate hat that came close to fitting!).
The event was held at the Contemporary Resort and it's the first time where we attended something Disney related where getting there early was not an advantage at all. In fact, if you book the Pirates and Pals event then I'd recommend getting there right on time! We were told to meet in a conference room at the Contemporary…it was crazy how HUGE the convention center area type place is and how many large conference rooms they have. We had a tough time finding where we needed to be!
I am so, so glad we dressed Kye up like a pirate for the night. He got SO MUCH attention and it was so nice to hear people stopping us and telling us how cute he was. I know it made him feel good, especially after a week where we were constantly stopped about Britt. He soaked up the solo time and the individual special attention. It was precious to see him so happy and excited!
As we were walking around we noticed the AMAZING view so went out on a deck to get pics of the castle!
For completing the scavenger hunt they gave Kye another new pin!!! Kid got hooked up with new pins this visit!
Don't get me wrong…it was a GREAT event. However, it was NOT cheap. And it is NOT something I'd do if I didn't have a son who also liked pirates and it's def not something I'd do without getting really into the whole pirate experience, ya know?
Once the doors to the conference room opened we went inside and were instantly impressed. When I called and read about the event I was a little leery at the cost when all the food that was included was "snacks." I'm shelling out the cost of a character meal and not getting a meal?!?! But the snacks were LEGIT. And they were unending. And delicious. And we tried to eat the most expensive stuff to make our money worth it haha. And we took several things with us too for the road 😉 And we basically pigged out. Which only made this an even BETTER gift for our food-obsessed child! He was in heaven when we told him he could drink lemonade and eat whatever he wanted.
We sat next to this guy and I KEPT getting confused and thinking he was real haha I think I said "excuse me" to him like a good 5 or 6 times!
Right when we walked into the room we saw Captain Hook and Smee waiting for the meet and greet. My talk with the cast member earlier came in handy (side note: ALWAYS get friendly with cast members, it often pays off in a big way!) b/c she told me not to rush to get in the line to meet them. So we enjoyed our snacks and waited until it was close to the end and then were among the last people to meet the characters. I think being last is an advantage because they aren't as rushed feeling. You don't have a line of a million people waiting so the characters are more relaxed and interact more.
We devised a plan and when it was Kye's turn he walked up and started singing "never smile at a crocodile" and Captain Hook got scared!
We, of course, thought of our recent Halloween costumes…Jordan as Smee was priceless and Z did make a great Captain Hook!
When we first arrived we talked a good bit to the cast member who checked us in and then I also got chummy with that other cast member later in the evening. I think our connections with them may be why Kye got chosen for an extra special job? Or maybe it was because he's so adorable 😉 Either way they asked Kye to be the leader of the Smee crew and he had the honor of carrying the flag all the way from where we were to the boat! So cool!!!
Smee has some BIG feet!!!
When we got to the boat Smee waved goodbye and our pirate captain took over for the voyage. He was great!!! Since characters don't speak it made sense that they had the switch and it was a very family friendly fun type experience. He really did awesome at keeping us all entertained the entire ride! The ONLY disappointment we had that night was that the boats we rode in were just plain boats. Zach and I both had expected a pirate themed boat?
It was a cold night and I was thankful Kye had chosen the outfit he did because it's actually fleece and very warm. We also brought along hot chocolate for each of us and Kye was more into that than he was the stuff our captain was talking about!
Gotta hold up your pirate hooks!
When we got to the spot to see the castle and the Wishes fireworks show I got pretty excited. It was a BEAUTIFUL spot! I told Zach if it wasn't a kid thing and wasn't pirates then it'd totally be romantic!!! Don't you think?!?! I took a couple videos of it too! Here is video one and video two!
On the way back from the fireworks we played Disney Trivia which was super fun! We won prizes for correct answers and they were all pirate themed gifts. At the end they said everyone who didn't win something could also choose a prize so we ended up keeping the pirate duck we won for Britt and letting Kye get a sword.
When the boat docked we were fed into a line to meet Peter Pan! I had to stop by the bathroom so we ended up being towards the end of the line as well. We visited with another family who was from Texas and they did the Pirates League experience that morning. They had three kids so I enjoyed getting some insider info about that while our boys played!
Right away Peter grabbed Kye's sword!
Kye was SO happy and it was a great surprise to get to meet Peter at the end of the night 🙂 We had a blast and I do highly recommend the Pirates and Pals Fireworks Voyage to anyone who is looking for something extra special to do at Disney. I do think it's much too expensive to justify it as a "must do" but if you have been to Disney before or have a special celebration then I do think it's well worth the cost! Kye has talked about it endlessly since we've been home and has already said it was the very best birthday ever and that the wants the exact same birthday next year (good luck convincing Daddy kid haha!). He has also told Britt that she needs to do Disney for her birthday AND that we need to take the baby to Disney as soon as it's born to celebrate it's literal birth day 😉 I have created a Disney fan for sure!!!
Kye was sleepy and silly on the way home and we sang "Pirates Life for Me" and got him tucked into bed right when we got back. Mrs. Charlotte was already asleep so he waited until the morning to fill her in on all the fun. It was a very, very special way to end our trip and I'm truly thankful we did it. I especially just loved having the quality time with Kye as he did AMAZING in the big brother role all week when most of what we did was catered towards Britt so I appreciated getting that one on one time with him and showering him with some special birthday loving!
We headed home first thing that next morning. Our kennel closes at noon on Saturdays and if you don't pick up by then you can't get them until Monday and get charged the extra fees so we like to get home quick 😉 I was SUPER sad to leave. Which really doesn't happen very often on trips. Usually when we head home, I'm ready. We all are "ready." We have fun on the trip but you get to a point where you are just ready to be back home and back into normal life. This trip was much longer than our usual ones (a full week!) but it was the first one I can think of in a long time where NONE of us were ready to get back to real life.
I have been very blessed in so many ways. On of which is with the ability to travel the world. I've visited so many amazing places and have had fabulous vacations. And I know people think I'm super mega lame for saying this…but it's true. This Disney trip was the BEST trip of my ENTIRE life. Dead serious. Every single day was perfection. I felt great (foot didn't bother me once…pregnancy was a breeze). We all got plenty of rest and sleep. Everyone was happy. Only ONE minor discipline issue the ENTIRE week. Kids got along beautifully. Zach had fun. Mrs. Charlotte was amazing. Weather was awesome. It was just flawless in every possible way. I love when Zach and I go away together on trips and do think it's important for us to do that for our marriage, but having my WHOLE heart there with me that week at Disney made it just so perfect. It was the first time I've gotten to experience Disney with BOTH of my kids and I just loved it. I loved how much THEY loved it and it was the trip of a lifetime that will be very difficult to beat!!!
It truly was a trip that will continue to live on for us as we talk about it constantly. When we got home Britt got out all the Disney figurines we have and talked about each one and how she saw them at Disney and put them in little piles with the other characters they go with. She also insisted on wearing a no-longer-glowing glow stick necklace from one of the fireworks nights. She is truly a Disney girl now and Mama is ready to make some more magical memories together ASAP!

I meant to say interest income is state and local tax exempt. Income on the sale of a bond is state and locally taxable.
Treasuries are state and local tax exempt and can make sense for ultra high net worth investors who resident in states like California and New York as well. Jim Cramer has been at this for 20 years and he doesn't know who his audience is. If he were speaking to those people, the advice is sensible. But, I agree. For 99% + of the CNBC audience, the recommendation should be "Go to BestCashcow and find a 2 year CD. The rates there are higher than the 2 year Treasury and you can way an early withdrawal fee and get out of the tariffs lead to massive inflation before 2 years."


Your designs are so wonderful - I stitch them out and you can hardly tell the front from the back. Your stitches are so beautiful and they actually make sense when you are sewing them out....most other designs jump all over the place. This is my favorite site now and I am sharing it will all my embroidery friends. Keep up the good work!!

A: This looks like an old bug in django-debug-toolbar. Do you happen to know which version you are using? Because the file looks like the one in this commit. Several fixes has been made to that file since then: this one, for example seems to address specifically your issue.
In any case, the version you're using seems to predate the 2nd of June, 2011. I would try looking into updating your environment.

Initially, presence of moist to dark spots forming mainly on mature leaves (Figure 1).
Subsequently, the spots spread and form blackish lesions often delimited by the veins (figures 2 to 4).
They gradually turn brown and become necrotic, and their center clears up. The leaf blade yellows more or less around the lesions.
A dense black down is visible on the spots on the underside of the blade, and sometimes on the blade in very favorable conditions (figure 5).
Severely affected leaves curl more or less (figure 5), become completely necrotic, and drop.
Fruits are sometimes affected showing longitudinal lesions covered with a blackish green.
Signs : presence on the lesions of a charcoal-black down (figure 6) made up of conidiophores and conidia hyaline and slightly curved, cylindrical, with 3 to 6 transverse partitions.
Possible confusion : rare

If you or your significant other has an overspending problem, this can put a strain on your relationship. You want to solve this issue before it gets worse, but you're not sure how to start. This article will walk you through twelve steps you can take to stop overspending. It may require you to work at it, but your relationship is worth it. You may even learn a few things by the end of this process.
The first thing you want to do is approach your significant other in a non-confrontational way. You can start by saying you want to monitor both of your spending habits. This takes the pressure off of one person's spending and makes it a couple issue versus an individual one. Once you start the conversation, it'll be easier to broach, and it'll open communication.
While you're having this conversation, try to find out what is causing your partner to overspend. There could be an underlying problem you're not aware of. This is an excellent time to get to the bottom of it. Maybe they have too much free time, or they're bored or lonely. You can work together as a couple to solve this issue.
Once you've started the conversation, create a budget with your significant other. If you currently have one, it is possibly time to revise and refresh it. Work with your partner to find out what your monthly income is and your debts. The point of this is to get your overspending partner to see how much money is they're using for 'luxury' items. If this is causing you to go into debt, you want to get this point across. It will be easier to do if the proof is in front of them, without you explicitly pointing it out.
This may be one of the trickiest parts of this whole process, but it's common sense. If you have a partner who can't go into a store without overspending, you should do the shopping. You could also do the shopping early each month or week, so you have an idea of whats left over. If your partner agrees, bring them along and teach them how to stick to a list. Don't buy anything extra while you're shopping.
If you're already going into debt, stop using your credit cards until they're paid off. If the overspender has to pay everything with cash, they might think more before buying. This will also stop you from getting deeper in debt, or at least curb it. Once you spend the money, it's gone. It's not like a credit card that you can rack up a balance.
You and your partner need something to work for. A financial goal will help give you something to focus on. Your first goal is to get out of debt. Once you complete this goal, consider setting up an emergency fund. You can also save for retirement or college if you have children. As soon as you complete a goal, have a meeting and set up another. This will help keep you on track.
If you've set your goals and you realize you need additional help getting out of debt, consider balance transfer cards. If you can pay off your credit card debt into the introductory rate, you'll save yourself interest fees. Most balance transfer cards have a 12 to 18 month 0 percent annual percentage rate. If may be smart to try and take advantage of this to cut down your overall costs. If you're not sure on a card, the Chase Slate is an excellent choice.
To keep your partner's or your spending on track, set a date each month to review your finances. You will be able to discuss and monitor your progress, as well as look for improvements. At first, you will more than likely see regression. However, you should see positive trends as the months go on. This is a learning process, and backsliding is normal. Take this time to encourage and praise one another for a job well done.
When you're doing the budget with your partner, save a little spending money. This will be a rough transition, to begin with, and this may help. Make it clear that this is all of the money for the month, and it has to count. Once these funds are gone, there isn't anymore until the next month. This will go a long way to helping curb overspending. Your partner won't feel so cut off, and they're less likely to try and spend behind your back.
There are outside resources you can join to help you. Debtors Anonymous (DA) can give you and your partner tools to help you transition from overspending. They have a 12-step program you can enroll in. This program also offers support from other people who have been in the same spot. They can provide advice and tricks to help you in a nonjudgmental atmosphere.
If your partner is resistant to fixing the problem, look into counseling. There is both couple and financial counseling that may be beneficial. These sessions can help find any deeper issue that may be causing your partner to overspend. Start out by attending joint meetings and split into individual ones as time goes on. You have a chance to improve your finances and your relationship at the same time.
If you're getting deeper into debt and your partner denies anything is wrong, you're at an impasse. Perhaps you would benefit from more extreme measures. Money disagreements and overspending cause a lot of divorces or friction, and this can act as a wake-up call. If anything, it will get the overspending party seriously looking at what is wrong. They may be more willing to work with you to fix the problem if they know you're serious. Divorce planning should never be done just to threaten, and it should be a last resort.
This article has talked about twelve steps you can take to curb overspending. You want to be happy and financially secure with your partner. This will be difficult if there is a money problem. Communication is the key to working out your problems.

When I married my husband, the two of us went on several shopping trips. During these shopping excursions, we looked for beautiful pieces of furniture to fill our new home with. At one store, I was drawn to a lovely oak, curio cabinet. After spotting this item of furniture, I instantly knew I wanted to display my extensive doll collection in it. Do you have a large collection of dolls, model cars, model trains, or snow globes you want to proudly display? Consider shopping for the perfect, stylish piece of furniture to put your beloved things in. On this blog, I hope you will discover smart tips to help you shop for the display case of your dreams. Enjoy!
When something is on sale at a local mall, you generally have no trouble walking in and buying the item.
If you have a collection of silver coins that you are finally ready to sell, you may be unsure of the best way to get the most for your coins. Here is a comparison of three options for selling silver coins to help you choose the right one to suit your needs.
If there is a local coin shop in your area, this may be the most convenient and most profitable method for selling your collection of silver coins. You will be able to negotiate a price face-to-face with the dealer, and you will also be able to walk out the same day with cash in hand.
When selling your silver at a local coin shop, it is important to remember that the dealer will be looking to turn a profit. While arming yourself with the latest spot price for silver and researching the unique numismatic value of your coins can help you get the best possible price, you should expect to sell your coins at less than their total value.
If you have a large coin collection that you are looking to sell, a coin show is an excellent way to get the best price for your entire collection. Coin expos will have several professional appraisers in attendance so you can get multiple opinions on the value of your collection.
When you attend a coin expo, you will have the opportunity to meet and possibly sell to other collectors who share your interest. This means that there is a potential for you to sell your collection at a better price than you would be able to receive from a coin dealer who is simply looking to resell your silver.
The only major downside to selling at coin expos is that they happen periodically. If you do not sell all of the coins you are looking to sell at a single expo, you may have to wait weeks or months to attend the next one, or turn to alternative methods of selling your collection.
Online auctions are often the best way to get the top price for each coin in your collection. As with coin expos, you will be able to sell your coins to other collectors. However, when you sell your coins through an online auction you will be selling to the highest bidder among collectors who have searched specifically for the coins that you have for sale. As long as you are willing to sell your coins individually over time, online auctions are an excellent option for any collector.
Every option for selling silver coins offers different levels of convenience and potential profit. Finding the right balance of these factors will help you choose the selling option that is perfect for you. For more information about selling coins, contact a company such as American Precious Metals Inc.


The flight from Paris to Italy is always anticipated because of the view of the Alps from the plane. This time the view was surreal. The solid cloud coverage from the north looked like the sea hitting the rocks on the shore. The clouds stopped at the mountains picks. On the other side of the Alps the sky was bright and clear. Italy!
The hotel had no special charm. But view from the little balcony on the Po river brightens the boring interior of the business hotel.
If you add to that a location, just off beautiful Piazza Vittorio Venneto surrounded by porticos with all the bars, restaurants and shops the hotel was completely OK. An addition they provided a nice complementary breakfast with cheeses and smoked sausages, fruits and cappuccinos. The savory breakfast as Vera likes to describe it. And than there were bathroom slippers which were so soft that putting them on after day of walking for 8-10 hours was such a delight that I took them with me to Barcelona.
After 1817, Vittorio Emannuele I decided to extend the city towards the river creating a square at the end of Via Po. The vast area to be leveled and the huge cost delayed the project. In 1825 G. Frizzi design featuring continuous arcades was accepted by the King and businessmen funding the project. The 7 meters difference in level between the entrance to the square and the bridge were cleverly masked by gradually altering the heights of the pavements and cornices along the facades.
Bars in Turin have all night happy hour. When you buy a drink you can pick up a plate of lively hors d'oeuvres from the selection set right at the bar as complementary snack. The most traditional include grilled red peppers cover with olive oil and anchovies, various little pizzas and foccachios, little sausages and cheeses. Bars get really creative with them to lure more customers.
After a few evenings I open for myself a drink which they call Americana and which consists of Campari, Martini Rosso, club soda and a piece of orange. I'm in love again!
A lot of young people were doing this instead of diner, but Patrick of course was not fooled and requested full diner after a drink and a snack.
My work hours will be even shorter now.
This breakfast sounds lovely. I will add it to the menu of my breakfast restaurant featuring all styles of savory breakfasts. That will teach people what breakfast is about!


A level 2 was issued for NE Spain mainly for excessive precipitation, large hail and to the lesser degree for severe wind gusts.
A level 1 was issued for N and E Spain mainly for large hail, severe wind gusts and excessive precipitation.
A level 1 was issued for N Italy and N Adriatics mainly for excessive precipitation, large hail and to the lesser degree for severe wind gusts.
A level 1 was issued for E Lithuania and NE Belarus mainly for severe wind gusts and to the lesser degree for marginally large hail.
The main feature will be rather quasistationary, large cyclonic vortex centered over S Norway. A short-wave trough at its southern base si forecast to cross Iberia during the Wednesday evening. Towards east, a ridge will stretch from Turkey towards Ukraine and the Baltic states. In between,in prevailing westerly to southwesterly flow, a cold front will cross Poland, continuing eastward while its southern part will become ill defined upon impinging on the Alpine and Carpathian ridge. Most of the DMC activity will be concentrated south or east of the cold front where moister airmass is observed - three notable regions will be N, NE Iberia, N Italy and N Adriatics and Belarus. These areas will be discussed in more detail below.
Ahead of the advancing short-wave, pressure is forecast to drop inland, enhancing moist easterly onshore flow. At the same time, mid-tropospheric flow will reach around 15 - 20 m/s, resulting in DLS between 20 and 30 m/s. Such values are very well conducive to well organised DMC, including supercells.
NWP does not predict significant overlap of abundant low-level moisture and steep lapse rates and thus CAPE values will likely not exceed 1000 J/kg except for the narrow coastal zones where dewpoints around 20 deg C are forecast. Storms may already be ongoing in the beggining of the period but the most widespread initiation is forecast in the evening hours associated with the short-wave trough approach. Some of the models show MCS development over NE Spain which will move offshore towards the morning hours.
Large hail and excessive precipitation seem to be the major threats, albeit probability of very large hail will be decreased by the lack of steep lapse rates. Severe wind gusts will be more likely inland with higher LCLs and deeper boundary layer. Situation is borderlining Lvl 1 / Lvl 2, with the most questionable factor being presence of MCS with enhanced excessive precip threat. Decided to go for a low-end Lvl 2 for the region with the expected highest coverage of severe.
Surface observations show dewpoints over 20 deg C near the coastline, decreasing towards the Alps. Despite the lack of steep lapse rates, CAPE values between 500 - 1000 J/kg are forecast over the region, perhaps even higher near the coastline. DLS around 15 m/s is suggestive of well organised multicells or even perhaps several short-lived supercells. Scattered to widespread initiation is forecast with the greatest threats being large hail and excessive precipitation. Wind gust threat will be reduced by the lack of stronger flow in the lower troposphere, but isolated downbursts in the stronger cells can not be ruled out. The highest threat is forecast near N Adriatics coastline in the late afternoon to evening hours.
Along the advancing cold-front, a convective line may be ongoing already in the morning over Poland, moving towards Belarus. In the environment of modest CAPE and moderate vertical wind shear, isolated severe weather is possible with well organised multicells. Degree of initiation is questionable in this situation with much disagreement between NWP especially regarding the southernmost extent of the initiation. Most probable threats will be isolated downbursts and marginally large hail.

KCON NY 2019 Day 2 Preview
Jack Wannan	Uncategorized	 July 7, 2019 July 7, 2019 2 Minutes
PHOTO: KCON NY Day 1 at Madison Square Garden. Credit: Andrew from Truly Daebak Podcast.
After KCON took centre stage at Madison Square Garden on Saturday night, the convention returns for it's second night. The evening will see six groups perform to conclude 2019's KCON.
Last night we saw NU'EST, TXT, ATEEZ, IZ*ONE and The Boyz perform. There was songs, missions and surprises throughout the evening. Tonight SF9, (G)I-DLE, AB6IX, VERIVERY, SEVENTEEN and fromis_9 will perform.
It's been an eventful weekend for AB6IX, who was performing in Hong Kong yesterday. Yes, yesterday. They took an airplane to New York and touched down in time to appear at the convention this afternoon. The rookie group debuted earlier in 2019 with the mini-album B Complete. The album featured title track "Breathe" which currently sits at 7 million Youtube views. The group has been one of the numerous successful boy groups that have debuted in 2019.
The night before showcased many rookies and newly former rookie groups. Tonight seems to be different, with older groups in SEVENTEEN and SF9 performing. SEVENTEEN have been around since 2015, making their discography one of the deepest on the lineup. Earlier this year they put out the single "Home" which has 32 million views on Youtube. SEVENTEEN performed at KCON NY in 2016 and have done KCONs in other areas as well since.
SF9 will be making their second KCON NY appearance on Sunday. Since the last time the group touched down in New York, the group has seen many comebacks. Their most recent one featured the title track "RPM." A year ago they put out the song "MAMMA MIA" which neared 10 million views on Youtube.
Fromis_9 is the only group who will be playing their second consecutive KCON NY. Last year they performed songs like "To Heart" and "DKDK," but this year come back with many new hits like "Love Bomb" and "FUN!" The recent mini-album from the group titled Fun Factory has seen consistent sales late after it's release, being the best project from the group so far.
VERIVERY is definitely the smallest group that is making an appearance at this year's KCON. Still in their rookie year, the seven-member group has put out two singles out of their two mini-albums. "Ring Ring Ring" and "딱 잘라서 말해 (From Now)" are the titles of those songs. "Super Special" is another song which was put out in 2018 and has a music video for it.
The sudden departure of EVERGLOW left the Saturday concert with a bigger boy group versus girl group disparity than before. The ratio for this concert is still 2-to-1 for boy groups, but it's an improvement from the night before. (G)I-DLE will be the second and final girl group of the evening on Sunday. The group sprung on the scene in 2018 with "LATATA" and "HANN (Alone)." The former "monster rookies' continued their success into 2019 with the songs "Senorita" and "Uh-Oh," their latest single which came out a week ago.
Similar to the night before, KCON will be livestreamed on their website. For countries who may have the event geo-locked in their area, the performances will eventually air on tape delay through the TV series M! Countdown.
After tonight, KCON New York 2019 will have concluded. The next convention will be KCON LA, which takes place on a whopping four-day stretch, from August 15th to 18th at the Staples Center and the Los Angeles Convention Center. The already confirmed acts for the event are Stray Kids, MAMAMOO, MOMOLAND, ONEUS, ATEEZ, Chungha, NU'EST, AB6IX, EVERGLOW, VERIVERY and IZ*ONE.

NEW ENGLAND New England 4000 Footers New Hampshire Adventures
Hiking Mt Moriah via Carter-Moriah Trail: New England 4,000 Footers

Mt Moriah is a 4,000 footer with a full, 360-degree view from its summit. The trail from Gorham, New Hampshire also has a surprisingly large number of views on the way up too. This is a great 9-mile day hike.
Carter-Moriah Trail
Its that awkward time of year again when the cold weather is here but there is no snow. All of us snowshoers, cross-country skiers, snowboarders, mountaineers and ice climbers are on the edge of our seats waiting for some glorious precipitation. But no snow is not a reason to not go out for a hike, especially when its on Thanksgiving!
I'm at the point in my pursuit to climb all of the White Mountain 4,000-Footers that I have several "odds and ends" to tie up and a few of the bigger single day ascents like Owl's Head and Isolation. I didn't bag Moriah when I did the Carter Ridge and Wildcat so today would be a great day for it! After all, the trail would be clear and quiet and I've heard the views are fantastic.
View Mt Moriah Hike via Carter-Moriah Trail in a larger map
I came up over Pinkam Notch and down over to Gorham, New Hampshire to do this hike. There was still now snow up in the Great Gulf, Huntington Ravine or Pinnacle Gully yet so I was glad I wasn't missing out. The hike actually begins at the end of a residential road and the parking situation was confusing- there's really no parking lot and its not really a cul-de-sac either... so I just pulled slightly off the road and the trailhead was at the end of the road.
The trail meanders along a ridgeline that eventually leads to Mt Moriah. What made this trail special was that there were multiple lookouts on the way up. Most hikes I've done in New Hampshire stay in the dense boreal forests and with only fleeting views. I was delighted to see that there was plenty to take my mind off the steep hike.
At about halfway up, I stopped for lunch and noticed something very unique; there was complete and utter silence on the trail. There was no wind, no birds, no bugs, no other hikers and no noise. Usually hiking here is such a social affair; today there was nobody! I enjoyed the quietude.
Its quite icy this time of year
Summit views from the top of Mt Moriah
If you are one who hates "false summits", then this mountain is probably not for you! The ridgeline hike plays all kinds of tricks with you and there were probably some 15 false summits along the way. Also, it was very, very icy in most parts of the trail. I mean, this was expected when hiking in late November, but there wasn't enough ice to don the crampons or micro-spikes, yet.
When the real summit finally came in to view, it was certainly worth the trip. There was a full panorama of views! The best was probably the view into the Dry River Wilderness and Valley, just to the East. You could also see most of the Carter Ridge and well into the Presidentials and Northern White Mountains. Way off in the distance I spied a pyramid-like mountain that was barely visible. It could have been Sugarloaf in Maine, almost 60 miles away! Regardless, it was a million-dollar view.
The Presidential Range from Carter-Moriah Trail
Well, I hope there's some real snow soon and that my next post is about some ice climbing or mountaineering!
Read. Plan. Get Out There!

Q: Dell PowerEdge R210 eSata, Port Multiplier According to some info i can find online that PowerEdge R210, the first R210 not the R210 II, is supposed to support port multipliers on its eSata port.  And i found examples online of some set up this way, well i for one can't get it working here.
I have a 4-bay Sata enclosure, i think its branded RaidStor on the back but i would have to crawl back behind the rack and double check that, that works with pretty much everything i have ever plugged it into.  But when i decided to move it over to the R210 which faithfully sits and churns away with storing backups from the network, i wanted to add this 4-bay enclosure to it for just ease of moving stuff around to external removable drives, i found that all it would see is the first drive, the other three are non-existent.  I checked Device Manager, told it to search for new hardware and it picked up the first drive, went to disk management and added that drive, partitioned it added a drive leter yada yada, everything went fine with the first drive but the other three that are in there don't show up.  But i can take the eSata cable going to the R210 and plug it into the eSata on my laptop even and i get all four drives so there must be something simple i'm missing here.
The only options in the bios for the eSata port are Automatic or Disabled, so i can't find anything else to set.  Its running in non-raid, AHCI, two internal hard drives and an optical drive, i would try putting a PCI-E eSata host card in it or a eSata port on a slot bracket and connect to an internal port to try that but i already have the PCI-E slot taken up by the Perc 6/e thats running the MD1000 attached to this server.
Anyone know if there is something else that needs to be done here?  Or is Dell lying about the eSata port on these being PM Aware?

A: I have just tested our Dell PowerEdge R210 and can comfirm that eSATA on debian Wheezy only picks up a single HDD in my 4 bay drive enclosure.  Luckily for us, I have an esata pci card that I can put it (will test this out soon).  I know my drive bay picks up fine in desktop PC's running Ubuntu 14.04 so I suspect that the esata port is ONLY for 1 drive.
Here is the manual for the R210 which doesn't make mention of multiple drives.
http://www.dell.com/downloads/global/products/pedge/en/PowerEdgeR210TechGuide_04052010.pdf
Note, we have ours in ATA mode because the EHCI mode wouldn't pick up our drives --- perhaps a bug in the bios, not sure.

A: have 2 x 1TB drives as raid 1 on SAS controller, added 1tb drive connected to eSATA It added it as drive D after dire warnings that it was my OS drive.
I transferred some data to D, backed up on D then shut down the r210 ii and removed D.
When I tried to reboot my RAID was called D not C and system failed to boot into Server 2008 R2. Switched of eSATA in BIOS, same problem. DO NOT use eSATA with BIOS 2.8.0 it seems so think it's a partition of your SAS RAID and when you remove the eSATA system won't boot to Windows ... I took the eSATA drive to a client, I'll get back and see if system works when I plug it back in ...
Plugged eSATA back into server, enabled eSATA, server booted fine :)
Now I just have to figure out how to remove eSATA drive from OS so I can disconnect it and boot server without it connected ...

1. US Security from Michael_Novakhov (87 sites): Eurasia Review: US, Mexico Cooperate To Reduce Cross-Border Drug Flow
By David Vergun
The Defense Department's statutory mission is to serve as the single lead agency for the detection and monitoring of the aerial and maritime transit of illicit drugs into the United States. Cooperation with allies and partners, such as Mexico, is critical to that effort, said a DOD official.
"Mexico remains the source of nearly all heroin seized in the United States and is a transit route for much of the cocaine available in our country," Matthew J. Flynn, deputy assistant secretary of defense for counternarcotics and global threats, said.
Moreover, Mexican cartels take advantage of uneven precursor chemical controls to manufacture deadly drugs, such as fentanyl and methamphetamine, inside of Mexico, which also make their way into the United States, he said.
"Despite the obstacles, Mexican law enforcement and military professionals, in cooperation with their U.S. counterparts, are bravely confronting the transnational criminal organizations that threaten both of our countries," Flynn added.
While much more remains to be done in the fight against Mexican cartels, it is important to recognize the efforts of the Mexican security forces that work daily to confront the transnational criminal organizations that threaten both the United States and Mexico, Flynn emphasized.
Two recent seizures highlight the efforts of Mexican agencies to disrupt the cartels' illicit activities, he said.
On Oct. 15, the Mexican army used radar data from a U.S.-provided radar in Hermosillo, a city in the northwestern Mexican state of Sonora, to track a plane carrying drugs, Flynn said.
Mexican soldiers moved to the area in which the plane appeared to land and seized a "poly-load" totaling 430 kilograms of assorted drugs: 56.6 kilograms of heroin, 4.1 kilograms of fentanyl, 177.2 kilograms of cocaine and 192.6 kilograms of crystal methamphetamine, he said.
On Oct. 20, the Mexican navy informed U.S. officials of a suspicious vessel off the coast of Colima state, Mexico, Flynn said. The Mexican navy maneuvered six of its vessels to the suspicious vessel, then boarded it and discovered 1.1 metric tons of cocaine.
A DOD official said that Mexican drug interdictions have been relatively low, and drug cartel violence remains at disturbingly high levels. "These organizations present a clear threat to Mexico and the Mexican government's ability to exert effective control over parts of its country."

Protocol es un sitio web estadounidense de noticias de tecnología, que cubre principalmente la influencia que esta puede tener en la política y las personas con poder que se encuentran detrás de la tecnología. Es propiedad de Axel Springer SE empresa propietaria del periódico Politico. El objetivo de Protocol es centrarse en las tres "P" de la tecnología: personas, poder y política.

La diferencia entre Protocol y otras publicaciones especializadas (como puede ser The Verge) es el tratamiento de la información y, por consecuencia, el público al que se dirige.

Propósito
Según sus creadores, el propósito de Protocol es ser un medio que analiza de manera imparcial la tecnología y el poder que hay detrás de ella para ayudar a los tomadores de decisiones.

Áreas de información
Protocol cubre los siguientes temas:

 La lucha del poder y la influencia el mundo de la tecnología.
 Los choques entre los legisladores y las grandes compañías tecnológicas.
 Las diferentes cuestiones relacionadas con la influencia de la tecnología en la gente y el planeta.

La página web tiene un total de ocho newsletters o boletines informativos (Source Code, Workplace, Pipeline, China, Fintech, Next Up y Gaming) de suscripción gratuita por correo electrónico, y los creadores no descartan crear en un futuro un servicio de suscripción pagada similar a Politico Pro, que tenga una herramienta de trabajo para los suscriptores y que también otorgue acceso a contenidos exclusivos.

Según Vanity Fair, Protocol ha sido lanzado en un mercado en el que hoy en día es muy difícil triunfar.

Braintrust
Braintrust es una comunidad de expertos y magnates tecnológicos de diferentes empresas, como pueden ser Google, Samsung o IBM, entre otros, que se reúnen para comentar asuntos relacionados con la tecnología, la productividad en el trabajo, la política y el Fintech. En estas reuniones colaboran con los periodistas para crear artículos que luego se publican en la página web del periódico.

Varios de los periodistas que colaboran provienen de periódicos y agencias reputadas, como pueden ser Wired, Reuters, The Wall Street Journal, The New York Times o Gizmodo, entre otros.

Controversias
Según DigiDay, varios trabajadores aseguran que han tenido discrepancias con Grieve (director ejecutivo) por su manera de querer hacer las cosas. Exempleados de Grieve, según este medio, lo definen como una persona demasiado ambiciosa, algo agresiva y también como "combustible". Grieve también mantuvo una discusión con Emily Dreyfuss, una editora y periodista de Wired.

Otra crítica que recibe Protocol es la de tener una falta de diversidad en la redacción, ya que la gran mayoría de empleados son blancos, y, además, durante la crisis del Covid-19, de los empleados despedidos por "motivos económicos", varios eran de color.

Según personas cercanas a Robert Allbritton, el creador, Protocol podría ser como TBD, un periódico de política local creado también por Allbritton y que fracasó.

Which Is Better to Learn First – C++ or C#?
By: Amarja Puranam
The world of programmers is a dynamic one. Good programmers can create wonders with the right kind of language used for the appropriate application. C++ and C# are two such languages that are used by programmers extensively.
What to learn first between C++ and C#, as a programming language is not an easy question to answer. The reason is simple. Both C# and C++ have brilliant uses. They both are in demand. Both of them have specific uses that the other cannot fulfill in totality.
Here's what we will do. We will understand these two programming languages individually to assess what should be your starting point. Deal?
About C++
We are looking at C++ first as it came much before C#. The C++ as a programming language was introduced in the early 1980's. It's been around for more than two decades now. Naturally, it has a lot of visibility in the programming world. The C++ has also been a foundational language for many others.It is widely used in the development of lot of applications.
Learning C++ definitely takes a lot of effort. Even in comparison with C#, it is more effort centric. An in depth understanding of programming, memory allocation and pointers is a must to learn C++. Some experts say that people with a mathematical mind can grasp this language with less effort. Mastery in C++ helps develop high-performing applications.
C++ is a good choice if the coding is for the purpose of hardware control like device drivers. It works across platforms. It is best suited for developing games and operating systems.
About C#
C#, pronounced as 'See Sharp' was introduced in 2000's. Microsoft introduced it as a Java competitor. It is a hybrid of Java and C as a language. It carries similar syntax like C. Brackets are used to differentiate between coding structures. It is an object oriented language that includes dependencies and libraries.
Learning C# , according to many experts, is not a tough job. If you already know Java, then learning C# will be a cake walk for you. Unlike C++, you do not necessarily have to know about memory allocation.
C# is also the most natural choice for web development and desktop applications. It is widely used to develop secure applications that can be easily run on the .NET framework.However, C# also can be used to work with Windows based programs. The way it is designed, C# helps developers improve productivity when designing web applications.
C++ and C# - Commonalities
C++ and C# do have some commonalities. The very first on is that they both have a similar code. The second one is that they are both object oriented languages. Third and an important commonality is that they are both compiled languages. This means that both of them convert your code into binary files before execution. Though there are some commonalities, one cannot be replaced with the other in a particular situation.
C++ and C# - Differences
Both C++ and C# have their base in the programing language C. Yet they differ a lot. Let's look at a few key differences.
1.Binaries
C++ and C# are both compiled languages. As a definition compiled languages turn code into binaries. The difference however is the volume of these binaries. C++ is light weight, whereas C# creates a lot of overhead in terms of binaries.
2. Garbage
You have to worry about garbage collection if you are using C++. You have to actively and manually allocate and deallocate memory. This is not the same case with C#.
3. Projects
C++ projects involve working with applications that directly work with the hardware. C# projects involve working with web based applications.
4. Platforms
C++ is cross platform whereas C# isn't. With a C++ you can work with a Mac, Linux and Windows. With a C# you typically work with Windows.
5. Performance
C++ is performance friendly compared to C#. The former is highly suitable where all other high level languages don't fit. The code in C++ is whole lot faster than C#.
If you know Java or C++, it is a lot easier to move to C#. On the contrary, moving from C# to C++ is not that easy. It is best to choose which ever works best for the product to be developed.
Learn C++ or C# languages based on the requirements of the environment you are in.
Another thumb rule is to pick between these two choices based on your career orientation. If you want to be a web developer, then definitely go for C#. If you want to be a person who wants to work on multiple platforms, then definitely learn C++.
It all boils down to choosing what fits your career aspirations and your aptitude. No matter what you choose, learn from the best and put it to test!

Yes, C++ Is great for both of those. Even more so C++ is better than c# for multi-platform support.
