Q: Running command line commands in Emacs, and receiving their output I want to run a set of command line commands in a loop within emacs, with the loop stopping when the user taps a key.
This is in order to see an ascii 'video' appear in Emacs, which stops when you press a key.
I thought it would be fun to have image-to-ascii bit of text as a comment (with the image coming from my mac's camera).
I use imagesnap to take the camera image, and jp2a to convert it to ascii. I think imagesnap is mac only. Here's the code I have so far:
(defun ascii-video-comment ()
    "Makes video comment, requires imagemagick, jp2a, imagesnap"
    (interactive)
    (shell-command "imagesnap -q ~/Desktop/emacs-snap.jpg")
    (insert (shell-command-to-string "jp2a --width=48 ~/Desktop/emacs-snap.jpg"))
    (shell-command "rm ~/Desktop/emacs-snap.jpg")
)

This just takes a snap from the camera, converts to ascii, inserts it into my file, and places the cursor after.
Like I say, I would like it to keep looping, giving the appearance of a slow ascii video, until i tap a key to select the current 'frame'.
Is this even possible?

EDIT
This is my current code, which I'm fairly happy with. It loops 20 times, and you can choose the current image by cancelling (C-g). Things seem to go wrong when you do it a second time though.
(defun ascii-video-comment ()
 "Makes video comment, requires imagemagick, jp2a, imagesnap"
 (interactive)
 (cl-loop repeat 20 do
  (shell-command "imagesnap -q ~/Desktop/ascii-video-comment.jpg")
  (cua-set-mark)
  (insert (shell-command-to-string "jp2a --width=120 ~/Desktop/ascii-video-comment.jpg"))
  (shell-command "rm ~/Desktop/ascii-video-comment.jpg")
  (comment-region (mark) (point))
  (cua-set-mark)
  (pop-global-mark)
  (sit-for 0.1)
  (undo)
 )
)

A: On your EDIT "final code": don't use interactive commands in a lisp program: you code becomes brittle and inefficient.
E.g., the doc string for shell-command (C-h f shell-command RET) explicitly states:

In Elisp, you will often be better served by calling call-process or
  start-process directly, since it offers more control and does not
  impose the use of a shell (with its need to quote arguments)

Also, use delete-file instead of (shell-command "rm ...").
Do not use cua-set-mark, pop-global-mark, and, especially, undo in programs.
Bind a variable instead:
(let ((beg (point)))
  (call-process "jp2a" nil t t "--width=120" "~/Desktop/ascii-video-comment.jpg")
  (comment-region beg (point))
  (sit-for 0.1)
  (delete-region beg (point)))

A: AFAIR, Emacs doesn't provide API to poll for pending events, so there are two options. UPD: disregard that, should've read the manual beforehand, Emacs does provide API to poll for pending events:
(defun start-printing-messages-2 ()
  (interactive)
  (while (not (input-pending-p))
    (loop-body-function)
    (redisplay 'force)))

If you want a delay between command execution, there's sit-for for you:
(defun start-printing-messages-3 ()
  (interactive)
  (while (sit-for 0.05)
    (loop-body-function)))

If you want that delay to start counting from beginning of loop body rather than its end (if your loop body might take significant time), you need to set up full-fledged timer execution: you basically run a function in a timer and add a post-command-hook that will kill that timer:
(defvar loop-run-count 0)
(defvar loop-timer-object nil)

(defun loop-body-function ()
  (setq loop-run-count (1+ loop-run-count))
  (message "The function was run %s times" loop-run-count))

(defun stop-printing-messages ()
  (when loop-timer-object
    (cancel-timer loop-timer-object)
    (remove-hook 'post-command-hook 'stop-printing-messages)))

(defun start-printing-messages ()
  (interactive)
  (setq loop-run-count 0)
  ;; post-command-hook is added via timer too, because otherwise it
  ;; might get called right after this function completes and this
  ;; would kill the timer that didn't even start yet.
  ;; get killed right after creation.
  (run-with-timer
   0.01 nil (lambda ()
          (add-hook 'post-command-hook 'stop-printing-messages)))
  (setq loop-timer-object
    (run-with-timer nil 0.01 'loop-body-function)))

A: You can wait for input with while-no-input and sit-for.
For the use case you describe, sit-for is what you need.
Note that you should combine the two shell calls with && or make a shell
script.
Here is a toy command that does what you need, but only flashing random numbers.
(defun flash-me ()
  "flash random number until you press a key"
  (interactive)
  (let ((beg (copy-marker (point)))
        (end (copy-marker (point) t)))
    (loop do (progn
               (delete-region beg end)
               (insert (shell-command-to-string "echo $RANDOM")))
          while (sit-for 1))
    (set-marker beg nil)
    (set-marker end nil)))


3. They want to hand off the McHenry Mansion and Museum to non-profit folks and shed responsibility. This is called privatizing.
4. They forecast a very dire budget future for Modesto. Have they seen the new property taxes? What about reserves?
5. Assist blighted neighborhoods. Good, BUT SELLING off small parks, usually in poorer places, is not the way to help achieve that.
Some ideas are just common sense, but please don't be like the Chamber of Commerce and advocate concrete and asphalt instead of trees.


THE Military Wives Choirs charity hopes to release an album to commemorate the centenary of the end of World War 1 – but needs support to make it happen.
Through the site Pledge Music, choir members are asking the public to pre-order the album now to allow them to get into the recording studio early next year.
The commemorative release will feature four brand new songs written especially for the Military Wives Choirs by composers in the pop, film and classical worlds around the themes of remembrance, patriotism and military life, as well as music from past and present referencing World War 1 marching songs and iconic service marches.
Anita, a member of Colchester Military Wives Choir, said: "Most of us understand how difficult it is to say goodbye to someone in the Forces, whether the person is going to a war zone or not.

Tune in Tuesday:5/4/10
With willing ears, and weary eyes, I willingly welcome you to today's wonderful installment of Tune in Tuesday features six wonderfully random albums.
Yes, that is a lot of W words and well, who wouldn't want to be wowed by the power of the words which Webster's willingly writes in their wholesome and widely read who's who of words.
Two white dudes from Akron, Ohio should not sound this damn good playing grungy, bluesy, inspired garage rock. Or in this case, basement rock where this album was actually recorded. But, alas, they do and we are better for it. If you are not a fan of The Black Keys, immediately stop reading and check out their music.
Songlines
The Derek Trucks Band
He is a child prodigy, nephew of Allman Brothers drummer Butch Trucks, touring partner of Eric Clapton, Grammy Award winner, and barely over 30. Yeah, we should hate him but he is so good that you can't help but love his work.
Recycled Recipes EP
Donovan Frankenreiter
This six song EP of covers is a great showcase of Donovan's smooth vocals. The song selection is superb, with such gems as, "Wonder Where the Lions Are" Theologians", and "Fortunate Son", to name a few.
Sunrise Over Sea
This little known Australian band is pretty impressive and debut at number 1 in his native home. He has got kind of a jammy feel to his playing with stand out tracks such as "Peaches & Cream", "What You Want", and "Seeing Angles.
Before the Frost/Until the Freeze
The latest album from this old school Georgia rock band. Recorded in the legendary Levon Helm's Woodstock barn studio, this 2 disc album (one disc, one digital download) is packed with rootsy, rocking, classic Crowes as well as a few slow tempo country tinged tunes.
This is the deftly produce debut album of the silky smooth yet funkily refined Corinne Bailey Rae. Her voice is comfortable and inviting and the music is perfect accompaniment but never over the top or running interference to mask the vocals.
Read, review, and respond.

25 albums you should own!
Over time, there have many great musical artists and from each artist comes an assortment of songs that become an album. In theory the sum of an album should be equal or greater than its parts (songs). If only this were true. Today, with streaming audio, and the ability to buy/download single songs, the allure and importance of the album has waned. Artists might release several EP's before they release a full length album.
Growing up, I had to roll the dice and hope that each album I saved for would be as good as the song I heard on the radio. Sadly, that was not always the case. Domo arigato Mr. Roboto!
However, some artists do indeed get it right and below is a list of 25 albums you might not know but you should own. This collection does not include live albums or greatest hits.
Also, I do not include any type of review for the below artists/albums. This is in an effort to allow you to form you own opinion, keep the blog reading to an acceptable time, and selfishly save me time writing the blog itself.
Twenty Five albums you should own! (In no particular order):

Animal Liberation Orchestra Fly Between Falls
Arcade Fire Funeral
Ben Harper Welcome to the Cruel World
The Black Keys Attack and Release

Q: Docker in "host" networking mode does not bind ports to the host On my development machine, I am trying to make a docker container connect to a mysql server on the host. To do this, I have set the networking mode to "host" like so:
phpfpm:
  image: mageinferno/magento2-php:7.0.8-fpm-0
  container_name: php7fpm
  restart: always
  hostname: phpfpm
  ports:
    - "9000:9000"
  environment:
    - APP_MAGE_MODE=developer
  volumes:
    - /Users:/Users
    - /usr/local/var/log/nginx:/var/www/logs
  net: "host"

The problem is that after I start the docker container, I can't telnet to localhost 9000 from the host. Connecting to the container on 9000 is not a problem when the container runs in bridge mode. The docker ps command shows:

CONTAINER ID        IMAGE                                  COMMAND                  CREATED             STATUS              PORTS               NAMES
6de4c973a34a        mageinferno/magento2-php:7.0.8-fpm-0   "/usr/local/bin/start"   4 seconds ago       Up 3 seconds                            php7fpm

Why doesn't the container bind the ports to the host? What am I missing here?
I am on OS X 10.10 using Docker for Mac (Version 1.12.0-rc3-beta18 (build: 9996))

A: Is there a reason you are trying to use host networking? It can be a bit tricky to set up and is mostly for pretty special use cases. At a minimum, you need to make sure the Docker host allows that port via something like:
iptables -I INPUT 1 -p tcp -m tcp --dport 9000 -j ACCEPT
Otherwise you are probably better sticking with bridge mode.

\section{Introduction}
Polarization transfer from a polarized electron to a proton in elastic scattering has
become a recognized method to measure the ratio of the proton's elastic electromagnetic form factors,
$G_E/G_M$ \cite{Jones:1999rz,Gayou:2001qd,Punjabi:2005wq,Milbrath:1997de,Barkhuff:1999xc,Pospischil:2001pp,PhysRevC.64.038202,MACLACHLAN2006261,PhysRevC.74.035201}.   Assuming the one-photon exchange approximation, the ratio of the transverse ($P_x$)
to longitudinal ($P_z$) polarization-transfer components is proportional to $G_E/G_M$ \cite{Akh74}.
This provides a direct measurement of the form factor (FF) ratio and eliminates many systematic uncertainties \cite{Perdrisat}.

Measuring the ratio of the same components of the polarization transfer to a \textit{bound} proton in \textit{quasi-free}
kinematics on nuclei, which is sensitive to the electromagnetic FF ratio,
has been suggested as a method to study differences between free and bound protons \cite{Milbrath:1997de,Barkhuff:1999xc}.
As such it can be used as a tool to identify
medium modifications in the bound proton's internal structure, reflected in the FFs and thereby in the
polarization transfer.  Deviations between measured polarization ratios in quasi-free and elastic scattering can be interpreted only by comparing the measurements with realistic calculations of nuclear effects.
This makes the deuteron an appropriate target for such measurements, since its nucleons can be highly virtual and it is a well understood nucleus from a theoretical standpoint \cite{Arenhovel}.

Quasi-free polarization-transfer experiments have been carried out on $^2$H and $^{12}$C at the
Mainz Microtron (MAMI) \cite{deep2012PLB,deepCompPLB,ceepLet}, as well as on $^2$H, $^4$He and $^{16}$O at Jefferson Lab (JLab) \cite{jlabDeep,Strauch,Paolone,Malov_O16}, in search of medium modification in the proton's internal structure.
These include measurements on far off-shell nucleons, characterized by high missing momentum, which is equivalent (neglecting final-state interactions (FSI)) to the struck protons having high initial momentum.
For $^2$H in parallel kinematics (negative $p_{\rm miss}$), it was shown that the deviations in $P_x/P_z$ from that of elastic $\vec ep$ scattering can be explained by
nuclear effects without the necessity of introducing modified FFs \cite{deep2012PLB,deepCompPLB}.
The individual components $P_x$ and $P_z$ were also measured.  The calculated values of these components deviated from the measurements, suggesting that the FSI effects are not fully reproduced \cite{deepCompPLB}.

In this work, we present the measurements of $P_x$ and $P_z$, and their ratio, in a previously unexplored kinematic region, where theoretical calculations predict that the FSI effects would be small compared to those in the kinematic regions of previous measurements (e.g. \cite{deep2012PLB,deepCompPLB}).  This makes this kinematic region useful for searching for genuine medium modifications, which would be obscured by large FSI effects in less favorable kinematical regions.

In the $A(\vec e,e'\vec p)$ reaction, a polarized electron with a known initial four-momentum $k$ scatters off a bound proton with initial four-momentum $p$, through exchange of a virtual photon with four-momentum $q$.  The final momenta of the knock-out proton,  $\vec p^{\,\prime}$, and the scattered electron, $\vec k^{\,\prime}$, are measured.   We define the ``missing momentum'' of the reaction to be $\vec{p}_{\rm miss}=\vec{q}-\vec p^{\,\prime}$, where $\vec q=\vec{k}-\vec k ^{\,\prime}$ is the momentum transfer.   In the absence of FSI, the initial proton momentum is given by the missing momentum, $\vec{p}=-\vec{p}_{\rm miss}$.  We refer to the missing momentum as being positive (negative) if $\vec{p}_{\rm miss}\cdot\vec q$ is positive (negative).  (See Fig.~\ref{fig:kinematics}.)
\begin{figure}[th]

\includegraphics[width=\columnwidth]{fig1_pos_neg_pmiss.pdf}
\caption{
Kinematics with $p_{\rm miss} < 0$ (left) contrasted with kinematics with  $p_{\rm miss} > 0$ (right).  In the kinematics on the left ($p_{\rm miss}<0$), the proton is initially moving in nearly the same direction as the virtual photon, while in the kinematics on the right ($p_{\rm miss}<0$), the proton is initially moving in the opposite direction of the virtual photon, and then changes direction by up to 180 degrees.

Previous measurements of $^2$H$(\vec e,e'\vec p)$  were obtained at $Q^2 = 0.40$ $({\rm GeV}\!/\!c)^2$ with positive $p_{\rm miss}$ reaching
175 MeV$\!/\!c$ \cite{deep2012PLB,deepCompPLB}.
The new data presented in this work obtained at $Q^2 = 0.65$ $({\rm GeV}\!/\!c)^2$ have improved statistical precision and extend the probed positive $p_{\rm miss}$ range up to 220 MeV$\!/\!c$.
This new kinematical region allows a more meaningful test for universality by comparing deviations in the ratio $P_x/P_z$ between $^2$H and a free proton to those of $^{12}$C and $^4$He
 in $p_{\rm miss}>0$ kinematics, complementing the earlier tests at $p_{\rm miss}<0$ in \cite{deep2012PLB,deepCompPLB,ceepLet}.

\section{Experimental Setup}
\label{sec:setup}
The experiment was performed at MAMI using the A1 beamline and spectrometers \cite{a1aparatus}.  For these measurements, a 690 MeV polarized CW electron beam with a $\sim$9 $\mu$A current was used. The average beam polarization was $\sim$80\%, measured twice daily with a M\o ller polarimeter \cite{Wagner,Bartsch}.  These measurements were cross-checked with a Mott polarimeter \cite{Tioukine}, and the two measurements were consistent with one another, up to a renormalization factor.  In the analysis, we considered the time-dependence of the beam polarization, which is described by a fit of the M\o ller  measurements using two linear segments (see the supplementary material).

 The beam helicity was flipped at a rate of 1 Hz. The target consisted of an oblong shaped cell (50 mm long, 11.5 mm diameter) filled with liquid deuterium. Two high-resolution, small solid-angle spectrometers with momentum acceptances of 20-25\% were used to detect the scattered electrons and knocked out protons in coincidence. The proton spectrometer was equipped with a polarimeter located close to the focal plane (FPP)  with a 7 cm thick carbon analyzer \cite{a1aparatus,Pospischil:2000pu}. The spin-dependent scattering of the polarized proton by the carbon analyzer allows the determination of $P_x$ and $P_z$ at the reaction point in the target \cite{Pospischil:2000pu} by correcting for the spin precession  in the spectrometer magnetic field.

In the analysis, cuts were applied to identify coincident electrons and protons that originate from the deuterium target, and to ensure good reconstruction of tracks in the spectrometer and FPP.  Only events where the proton scatters by more than 8$\degree$ in the FPP were selected (to remove Coulomb-scattering events).

We present measurements at two kinematic settings, labeled E and F, given in Table \ref{tab:kinematics}.  These complement previous measurements \cite{deep2012PLB,deepCompPLB}, the kinematic settings of which are listed in the supplementary materials.  This work primarily focuses on the data taken at setting E, with large positive $p_{\rm miss}$ and $Q^2=0.65$ $({\rm GeV}\!/\!c)^2$, where theoretical calculations (see Section \ref{sec:calculations}) predict smaller FSI effects than in previous settings.

\begin{table}[h]

Also shown is the range of $\theta_{pq}$, the angle between $\vec{q}$ and $\vec p = -\vec{p}_{\rm miss}$. For the kinematics of the earlier $^2$H data sets, see the supplementary materials.}

\end{tabular}
\end{center}
\label{tab:kinematics}
\end{table}%

We also took data at $Q^2=0.40$ $({\rm GeV}\!/\!c)^2$ and $p_{\rm miss}\sim 0$ (setting F) during the same run-period.  The larger cross-section in setting F allowed us to obtain large statistics, and to compare the measurements with those at a similar kinematic setting (A) in Refs.~\cite{deep2012PLB,deepCompPLB} as a cross-check.

\section{Measured polarization-transfer}
The polarization-transfer components, $P_x$ and $P_z$, and their ratio $P_x/P_z$ measured in setups E and F, along with the earlier $^2$H data from MAMI \cite{deep2012PLB,deepCompPLB}, are shown in Fig.~\ref{fig:raw_r_vs_pmiss}.  The new data in setting E ($Q^2=0.65$ $({\rm GeV}\!/\!c)^2$) extend the range of our positive $p_{\rm miss}$ data, matching the coverage of the earlier data in the negative $p_{\rm miss}$ region (setting D, at $Q^2=0.18$ $({\rm GeV}\!/\!c)^2$).

The errors shown in Fig.~\ref{fig:raw_r_vs_pmiss} are statistical only.  The systematic error in these measurements is due to a few sources. The
largest contribution to the uncertainty in the polarization components
$P_x$ and $P_z$ is the beam polarization. It was measured periodically during
the data taking by Moller and Mott polarimeters with an estimated
accuracy of 2\% (see the supplementary material). The carbon analyzing power
in this kinematic region is known to about 1\% \cite{Pospischil:2000pu,AprileGiboni:1984pb,Mcnaughton:1986ks}. However, the
ratio $P_x/P_z$ is independent of the analyzing power and beam polarization.
The uncertainty in the spin-precession evaluation is dominated by the
reaction vertex reconstruction, and was evaluated to contribute 0.8\%.
The reconstruction of the momentum and scattering angle of the detected
particles contribute 0.4\%. The uncertainty due to the beam energy is 0.5\%.
Contributions due to detector alignment are negligible. Helicity-independent
uncertainties, such as target density, detector acceptance and efficiency, etc.,
largely cancel out due to the frequent flips of the beam helicities.
Software cuts applied in the analysis were studied and contribute 1.5\%.
The total estimated systematic uncertainties are 3\%, and 2\% for the
polarization components and their ratio respectively.

\begin{figure}[ht!]
\begin{center}
\includegraphics[width=\columnwidth]{fig2_pol_vs_pmiss.pdf}
\caption{
The measured polarization components $P_x$ (top), $P_y$ (second panel) and $P_z$ (third panel), and the ratio $P_x/P_z$ (bottom) measured in this work (red and purple, filled), and the earlier $^2$H data sets \cite{deep2012PLB,deepCompPLB} (open symbols).  The vertical error bars here (and in the other figures)  are statistical only.  The horizontal bars represent the standard deviation of the $p_{\rm miss}$ in the bin.
}
\label{fig:raw_r_vs_pmiss}
\end{center}

We find that $P_x$ shows mild variation between different kinematics, but $P_z$ varies greatly between data sets, approaching 1 at large $p_{\rm miss}$ for setting E.
The $P_y$ component, which vanishes in elastic scattering \cite{Akh74}, is nearly zero for each of our data sets, indicating that this component is not strongly affected by nuclear effects.

The polarization-transfer components for setting F ($p_{\rm miss}\sim0$, $Q^2=0.4$ $({\rm GeV}\!/\!c)^2$) agree within the errors with the earlier measurements which were obtained in a similar kinematic\footnote{These data sets have the same $Q^2$ and cover the same range in $p_{\rm miss}$, but had different beam energies: 600 (690) MeV$\!/\!c$ for setting A (F).} (setting A), providing further support that the normalization due to beam polarizations is also within the error.   However, settings E and B (which overlap in positive $p_{\rm miss}$ but have different $Q^2$: 0.65 and 0.40 $({\rm GeV}\!/\!c)^2$ respectively) are very different from one another in $P_z$.

A more coherent picture is obtained by dividing the measured polarization components by the expected ones for a free-proton, and by examining them as functions of the struck-proton virtuality, as discussed in Sec.~\ref{sec:calculations} below.

\section{Comparison of measurements to elastic $\vec ep$ scattering and $^2$H$(\vec e,e'\vec p)$ calculations}
\label{sec:calculations}

The dependence of the polarization transfer components and their ratios on $Q^2$ (due to the form factors) and other kinematic effects are reduced by dividing the measured values by the expected ones for elastic $\vec ep$ scattering with similar kinematics \cite{deep2012PLB,ceepLet,deepCompPLB,movingProtonPLB}.
We use the ``moving-proton'' prescription \cite{ArenhovelMoving,movingProtonPLB}, rather than the expressions for elastic scattering off a resting proton \cite{Akh74}.  In this prescription, each measured quasi-elastic event is compared to an elastic event that has the same incident electron
energy ($k_0$), the same magnitude of the four-momentum transfer ($Q^2$), and the same initial proton momentum ($-\vec p_{\rm miss}$)
as the measured quasi-elastic event. Full details on the expressions for the polarization transfer observables  are given in \cite{ArenhovelMoving,movingProtonPLB}.  In Fig.~\ref{fig:corrections}, we compare
the polarization-transfer components calculated for the resting-and the moving-proton kinematics. We show in this figure the ratios $\frac{(P_x)^{^1\!\rm H}_{\rm moving}}{(P_x)^{^1\!\rm H}_{\rm resting}}$, $\frac{(P_z)^{^1\!\rm H}_{\rm moving}}{(P_z)^{^1\!\rm H}_{\rm resting}}$, and $\frac{(P_x/P_z)^{^1\!\rm H}_{\rm moving}}{(P_x/P_z)^{^1\!\rm H}_{\rm resting}}$,
as calculated for the kinematics of the measured $^2$H($\vec e,e'\vec p$) events.  We note that for new kinematics (E) the effect of the moving free proton prescription increases $P_x$ and decreases $P_z$  (unlike the effect in the other kinematics), resulting in a larger effect on $P_x/P_z$.  More details are found in the supplementary.

\label{fig:corrections}
\end{figure}

Following the convention used in \cite{deep2012PLB,ceepLet,deepCompPLB,movingProtonPLB} we use the struck-proton virtuality (``off-shellness''), $\nu$, as our parameter of choice.  The virtuality is defined as \cite{deep2012PLB}:
\begin{equation}
\nu\equiv\Big(m_{A}c-\sqrt{m_{A-1}^{2}c^{2}+p_{\text{miss}}^{2}}\Big)^{2}-p_{\text{miss}}^{2}-m_{p}^{2}c^{2},
\end{equation}
where $m_p$, $m_{A}$ and $m_{A-1}$ are the masses of the proton,  target nucleus (deuteron) and residual nucleus (neutron, assumed to be on-shell) respectively.  The virtuality has been shown to be a more useful parameter than $p_{\rm miss}$ when comparing the double ratios $\frac{(P_x/P_z)^A}{(P_x/P_z)^{^1\!\rm H}}$ in data sets for different nuclei and with different kinematics \cite{deep2012PLB,deepCompPLB,ceepLet}.  The virtuality dependence of the polarization transfer can be different for positive and negative $p_{\rm miss}$ \cite{deep2012PLB,ceepLet,deepCompPLB}.

We extracted the ratios of the polarization-transfer components for the deuteron to those of a free proton,  $\frac{(P_x)^{^2\!\rm H}}{(P_x)^{^1\!\rm H}}$ and $\frac{(P_z)^{^2\!\rm H}}{(P_z)^{^1\!\rm H}}$, as well as the double ratio $\frac{(P_x/P_z)^{^2\!\rm H}}{(P_x/P_z)^{^1\!\rm H}}$, where the denominator expressions are calculated  event-by-event using free moving-proton kinematics \cite{ArenhovelMoving,movingProtonPLB}.  These ratios are shown as functions of $\nu$ in Fig.~\ref{fig:compDeep}, and compared with those from previous MAMI $^2$H data sets \cite{deep2012PLB,deepCompPLB}.  We find that the differences between the measured polarizations and those of elastic $\vec ep$ scattering in setting E are relatively small compared to those of negative $p_{\rm miss}$ measurement (setting D), where the virtuality is comparably large but the $Q^2$ is smaller.  This suggests that FSI effects are smaller in setting E than in the other settings.

We compared our measurements to state-of-the-art calculations of the expected polarization transfer for quasi-elastic $\vec ed$ scattering \cite{Arenhovel}. These calculations are based on a realistic potential for the wave functions, i.e. FSI  for the scattering state, and include meson exchange (MEC), isobar (IC) currents, and relativistic contributions (RC) of lowest order. For the nucleon form factors, the parameterizations of Bernauer \textit{et al}. \cite{Bernauer} are used.
The ratios of the calculated $\vec ed$ polarization-transfer to those of elastic $\vec ep$ scattering are shown as curves\footnote{We use solid black lines for settings D and E in Fig.~\ref{fig:compDeep}, for consistency with Fig.~\ref{fig:models}.  The calculations for the other settings in Fig.~\ref{fig:compDeep} are shown as grey dashed lines.} in Fig.~\ref{fig:compDeep}, along with our measurements.  Also shown are these ratios calculated event-by-event, and then averaged in each bin.  These are shown as filled (open) stars for sets D and E (sets A,B and F).

We find that the measured $P_x/P_z$ for all the data sets agree very well with the calculations.  The measured components $P_x$ and $P_z$  for both data sets E and F are on average about 3\% above the calculations, which is consistent with the systematic uncertainty on the normalization due to the beam-polarization.  Accounting for this, the measured components for set E agree with the calculation within the errors with $p$-value = 0.11, which is significantly better than in the other kinematic settings\footnote{See the supplemental materials for details.}.

In order to determine which phenomena have the strongest effects on the calculated polarizations, we ran several variations of these calculations, with different effects (FSI, etc.) included or excluded.  The results of these calculations, divided by those of elastic scattering \cite{movingProtonPLB,ArenhovelMoving}, are shown in Fig.~\ref{fig:models}.  The calculations on the right correspond to the kinematics of setting E in this work, with $Q^2 = 0.65$ $({\rm GeV}\!/\!c)^2$ and $p_{\rm miss} > 0$, while those on the left side of the figure correspond to the kinematics of setting D \cite{deep2012PLB,deepCompPLB}, with $Q^2 = 0.18$ $({\rm GeV}\!/\!c)^2$ and $p_{\rm miss} < 0$.
The solid black line is the full calculation in the distorted-wave impulse approximation (DWIA) which includes MEC, IC, and relativistic corrections.  It is identical to that of Fig.~\ref{fig:compDeep}.  The FSI effects, which are included in the DWIA but not in the plane-wave Born approximation (PWBA), strongly affect the $P_z$ component in the $p_{\rm miss}<0$ range, and are greatly reduced in the positive $p_{\rm miss}$ region.
The combined effects of MEC, IC, and RC, do not exceed 15\%.

The predicted differences between the \textit{full} quasi-elastic calculation and elastic scattering are very small when the virtuality is near zero, and increase with larger virtuality.
In general the deviations on the right-hand side, representing the presently explored kinematics (larger $Q^2$, $p_{\rm miss}>0$), are smaller than than those on the left-hand side \cite{deep2012PLB,deepCompPLB}, (low $Q^2$, $p_{\rm miss}<0$).  Moreover, the large increase observed for $P_z$ in the negative $p_{\rm miss}$ range is largely eliminated in the the present kinematics.  This makes calculations in this kinematic range less sensitive to the included effects, and these kinematics more suitable for looking for new phenomena.

In order to estimate limits on possible medium modifications, we reran the calculations on all of the MAMI $^2$H data sets, scaling the form factor ratio $G_E/G_M$ from \cite{Bernauer} by a constant factor $R$.
For each value of $R$ we compared the calculations to our measurements and computed the associated $p$-value.  From this, we calculated the range in $R$ for which the $p$-value was $\ge$ 5\% (95\% confidence level).
We accounted for the systematic errors by adding them (multiplied by 1.96 for 95\% confidence) in quadrature with the statistical errors.
These systematic errors include 2\% for the measurement of $P_x/P_z$ and another 0.5\% for the uncertainty of the $G_E/G_M$ parameterization \cite{Bernauer}.

The results for all of the MAMI $^2$H data sets (this work and those of \cite{deep2012PLB,deepCompPLB}) are shown in Fig.~\ref{fig:upperLimits}.  We find that each of these data sets is consistent with the hypothesis $R=1$.
The 95\% confidence interval on $R$ for the combined data set is from 0.966 to 1.062.  This implies that medium-modifications effects on $G_E/G_M$ (if they exist) are constrained to be between $-$3.4\% and 6.2\%.
This does not exclude medium modifications that keep $G_E/G_M$ constant.

\section{Universality of  the double ratio $\frac{(P_x/P_z)^A}{(P_x/P_z)^{^1\!\rm H}}$}
\label{sec:universality}

A good agreement between the double ratios $\frac{(P_x/P_z)^A}{(P_x/P_z)^{^1\!\rm H}}$ in the earlier $^2$H data at $p_{\rm miss}<0$ from Refs.~\cite{deep2012PLB,deepCompPLB} and those measured for $^{12}$C at MAMI in Ref.~\cite{ceepLet} and for $^{4}$He at JLab \cite{Paolone}, was reported in Refs.~\cite{deep2012PLB,ceepLet}.
To test if the new $^2$H data at $p_{\rm miss}>0$ are likewise compatible with similar measurements in other nuclei at the same virtuality range, we also compare the double-ratios for the new $^2$H data and to those of the previous measurements on $^{4}$He at JLab\footnote{The double ratios presented in \cite{Paolone} have been adapted to use moving proton kinematics \cite{ArenhovelMoving,movingProtonPLB} in their denominator, for a consistent comparison with the MAMI data.  See the supplementary material.} \cite{Paolone}, and $s$-shell knockout\footnote{Polarization transfer in $p_{3/2}$-shell knockout was also measured in \cite{ceepLet}; however, since Fig.~~\ref{fig:ceep_deep} compares the carbon data set with  $^2$H and $^4$He, which only contain $s$-shell protons, only the $s$-shell knockout from carbon is shown in the figure.} on $^{12}$C \cite{ceepLet} at MAMI.  As shown in Fig.~\ref{fig:ceep_deep},
we find that the double ratio in the new $^2$H data agrees very well with the $^4$He and $^{12}$C in the positive $p_{\rm miss}$ region, just as it was shown for the earlier $^2$H data in Refs.~\cite{ceepLet,movingProtonPLB}  in the negative $p_{\rm miss}$ region.

\begin{figure}[ht]
\begin{center}
\includegraphics[width=\columnwidth]{fig7_universality.pdf}
\caption{
The double-ratios $\frac{(P_x/P_z)^A}{(P_x/P_z)^{^1\!\rm H}}$ measured in this data set (red and purple filled symbols), compared to the earlier $^2$H data sets \cite{deep2012PLB,deepCompPLB} (green, open symbols),  $s$-shell knockout in $^{12}$C data sets \cite{ceepLet} (black filled symbols), and $^4$He data \cite{Paolone} (yellow filled squares).  In each of these ratios, the denominator is calculated using the ``moving-proton'' prescription \cite{ArenhovelMoving,movingProtonPLB}.  The $^4$He data shown was taken at $Q^2$= 0.8 $({\rm GeV}\!/\!c)^2$.}
\label{fig:ceep_deep}
\end{center}
\end{figure}

The inclusion of setting E in the test of the universality of the double-ratios (Figure \ref{fig:ceep_deep}) reveals the importance of accounting for the proton's initial momentum \cite{movingProtonPLB,ArenhovelMoving} in comparing the measured polarization ratio $P_x/P_z$ to that of elastic scattering.  The moving-proton prescription, introduced in \cite{movingProtonPLB,ArenhovelMoving}, supersedes the earlier ``resting-proton'' prescription, where the bound proton's Fermi motion was not taken into account, and the elastic kinematics
assumed the proton to initially be at rest.  In \cite{movingProtonPLB}, we found that the effect of using the moving instead of the resting prescription on the double ratio was small for the kinematics available at the time ($\sim$3\% for negative $p_{\rm miss}$, and up to $\sim$10\% for positive $p_{\rm miss}$).  However, we found that this effect is much larger for kinematic setting E, causing the double ratio to increase to 1.5 times larger in the ``resting'' prescription than in the moving prescription, as shown in the supplementary material.  Therefore, the use of the moving (rather than the resting) kinematics is a necessary ingredient in maintaining the universality of the double ratio $\frac{(P_x/P_z)^A}{(P_x/P_z)^{^1\!\rm H}}$.

\section{Conclusions}
We have observed that the differences in the polarization-transfer components between the deuteron and hydrogen are small in the measured region of positive $p_{\rm miss}$ and large $Q^2$, compared to previous measurements at negative  $p_{\rm miss}$ and small $Q^2$, as predicted by the calculations.  This implies that the effects of FSI are small in this region, making it a good region for searching for medium modifications.

The measured polarization-components $P_x$ and $P_z$ for the new $^2$H data, as well as their ratio, $P_x/P_z$, are consistent with the calculations within the errors.  This tests the validity of the calculations on the positive missing-momentum region, and shows no evidence of medium modifications on the FF ratio $G_E/G_M$.  Further, we have established constraints on possible modifications to this ratio on the order of a few percent.

We also find that, when dividing our measured values by the polarization-transfer for a free moving proton \cite{ArenhovelMoving,movingProtonPLB}, the double ratios $\frac{(P_x/P_z)^A}{(P_x/P_z)^{^1\!\rm H}}$ from the $^2$H measurements in the new kinematic region are in agreement with measurements for $^{4}$He and $^{12}$C, just as they were found to be in agreement in previous $^2$H measurements.  This supports the universal behavior of the double ratio.

Q: Decode image file to extract image header information and modify it (with python) I'm reading an image file of dpx format, and want to extract the "Orientation" in the image section of the header, and also modify it. I have never tried to interpret binary data, so I'm a bit at a loss. I'm trying to use the struct module, but I really don't know how to do it properly. The file header specification is here:
http://www.fileformat.info/format/dpx/egff.htm
Thanks.

A: There seems to be a constant offset to the Orientation so if this is all you want to change then I wouldn't bother trying to parse it all, just work out the offset (which I think is just the size of the GENERICFILEHEADER plus one byte for the high byte of the orientation word) and read / manipulate it directly.
Using a bytearray would be my first choice. The offset varies by one depending on if it's in a big or little endian format, so something like this might work for you:
b = bytearray(your_byte_data)
big_endian = (b[0] == 0x52)
offset = 768 + big_endian
current_orientation = b[offset]  # get current orientation
b[offset] = new_offset           # set it to something new
open('out_file', 'wb').write(b)

A: You might want to consider using Imagemagic to do that. Open source and supports the dpx format.

A: The Python Imaging Library PIL has am attribute .info that might return the relevant data

Today, we generally vote for a single instance, like an article or post. However, rarely do we agree with everything within an idea's description: rather, we like just particular parts of the ideas, and would like to get them realized. It's much easier to agree upon a single feature, rather than entire ideology of an arbitrary idea.
So, this would be a special service on the web that allows authors to generate an HTML IDs for blocks of text for granular voting on statements within those texts, meanwhile collecting information about voter's skills and resources potentially available for realization of those statements.
The hoped outcome is that this would enable groups of people interested in realization of particular features contained within fractions of the texts during their reading process online, to self-organize into purposeful interest groups, and that would allow faster implementation of actual features that people want.
How would this work?
The process would involve idea authors and the general public (the readers), and this special Service (or tool).
The idea authors describe their ideas anywhere, e.g., in their personal blogs or any sites that support HTML.
The idea authors log into the Service's website to generate a unique HTML ID, -- text block identification token.
The idea author then sees the HTML ID for their idea text, and JavaScript that generates clickable objects for each statement within the idea text with the ID.
The idea author then surrounds their idea text with a neutral tag like SPAN, and copies the script, which converts it to paragraph-wise or sentence-whise click-able object, whereby on each paragraph or sentence the reader can vote, and see number of votes, as well as usernames of people who had showed their interest to take part in realizing that aspect of an idea. Merely hovering on a sentence would show the number of people that want the feature described in the sentence, and would like to support someone trying to realize it.
The reader who wants to participate clicks to join the particular statement. In case the reader is already logged-in, the number turns to higher count, otherwise the reader is asked to register or sign in.
The reader who is registering can optionally fill-in some information about his skills and areas of competences available.
The idea author then is able to view all the participants in the list, as well as every other participant can view it by logging into the Service's website with their account.
Groups of people with shared interest in realizing particular features emerge, informed about each other's existence and potential resources available: so someone who wants to get collaborators, can easily have a list of people to contact with, and more realistically think of realizing one or another aspect of interest.

Yes, of course, it could be sentence-by-sentence. What's attractive about this idea, is that it could be easy to make it hyper-scalable, due to simple model.
Yes, people rarely agree with everything, but more about the parts.

Particle filters are sequential Monte Carlo estimation methods with applications in the field of mobile robotics for performing tasks such as tracking, simultaneous localization and mapping (SLAM) and navigation, by dealing with the uncertainties and/or noise generated by the sensors as well as with the intrinsic uncertainties of the environment. This work presents a field programmable gate arrays (FPGA) implementation of a particle filter applied to SLAM problem based on a low cost Neato XV-11 laser scanner sensor. Post processing is performed on data provided by a realistic simulation of a differential robot, equipped with a hacked Neato XV-11 laser scanner, that navigates in the Robot@Factory competition maze. The robot was simulated using SimTwo, which is a realistic simulation software that can support several types of robots. The simulator provides the robot ground truth, odometry and the laser scanner data. The results achieved from this study confirmed the possible use such low cost laser scanner for different robotics applications.

A Sokolowski Twin Pack

July05 Ron Hynes.jpg
Ron Hynes at the Fat Cat Blues Bar in St. John's, Newfoundland
Visitors to the Atlin Arts and Music Festival this weekend can look forward to an excellent lineup of films to round out their entertainment schedule, thanks to the Yukon Film Society.
Featured on Saturday is a pair of films that feature some breathtaking vistas of the beauty of Canada from a Yukon filmmaker, as well as a look at an iconic Canadian troubadour.
Dan Sokolowski is the programmer of the annual Dawson International Film Festival.
A graduate in fine arts from University of Ottawa, he's also an accomplished filmmaker, whose most recent work, Degrees North, is a lyrical blend of stunning landscape photography, original artistic animation and a thoughtful musical score.
Filming with a pair of 16mm Bolex cameras, Sokolowski made 10 different cross-country road trips, covering a distance of over 50,000 kilometres. His idea was to capture the essence of a Canadian panorama, from south to north.
Starting at the southernmost tip of the country, Pelee Island at 42 degrees latitude, is on the same parallel as parts of northern California.
Sokolowski's camerawork emphasizes the lush vegetation of the region and the alluring waterscape.
His vista is soft and flowing, in sharp contrast to the rocky prominence of the next area of the country he captures, the northern shore of Lake Superior, at 48 degrees latitude.
From here, Sokolowski moves ever north, through the western badlands, finishing up in the Yukon and above the Arctic Circle in the Northwest Territories.
His film is totally devoid of narration, with only the lapping of the waters, the cry of loons and the soft serenade of waterfowl for accompaniment, as well as a gentle score from Halifax's Peter Togni and his combo, and vocal work from Ottawa's Ian Tamblyn.
Degrees North is a captivating experience not to be missed.
Ron Hynes's craggy visage has graced Newfoundland stages for some 40-plus years. He started playing guitar at age nine, switching from piano lessons to playing Buddy Holly licks, and by age 16 he was offered a recording contract.
The Man of a Thousand Songs, a new musical documentary produced in St. John's, is a candid and frank portrayal of the ups and downs of his career.
Majoring in coffee house at university, in his words, he slept on pool tables and toured all over the island.
In 1976, Hynes scored big on the folk circuit with his poignant recording of Sonny's Dream, a song that's been covered by many artists, which he claimed he dashed off in 10 minutes.
The film details his years with a local musical sketch comedy group called the Wonderful Grand Band, who were the successors to the famed CBC stars CODCO, until the death of group member Greg Sexton and the disbandment of the troupe.
Hynes's professional life was marred by a deep-seated cocaine addiction in the mid- '90s that almost destroyed him, bringing out a troubled facet of his personality that he refers to in the film as "the other Ron".
Hynes is acknowledged by his peers as one of the most prolific and durable songwriters around. Sokolowski's film is a glowing tribute to his versatility and heartfelt genius.
The Man of a Thousand Songs plays at the Atlin Arts and Music Festival Saturday, July 7 at 10:15 a.m. in the Globe Theatre, followed by Degrees North at noon, with Sokolowski in attendance.

Why is handmade jewellery so expensive??!
As an advocate of handmade and someone who makes handmade jewellery I so often hear "the jewellery is lovely, it's really unique but why is it so expensive" or "what a rip off" and "it's just too much" many, many other comments like this. Truthfully, I used to be like this, until I started making it as a business myself.
So here it is from my perspective as a designer running an independent small handmade jewellery business and I hope it helps you understand.
When you purchase a handmade item you are for the most part purchasing a higher quality piece than if you buy mass-produced. Ok sometimes, like in anything, you may well come across a handmade piece that has been poorly made, maybe it has been rushed or made by someone still learning – it can happen.
But back to the point, Usually the finest material is used in handmade jewellery - high quality stones and stringing material such leather or silk rather than cheap materials - I know that I certainly take pride in what I make and couldn't conceive of using anything other than the best materials and doing anything other than the best job I am able to. With this in mind you know that handmade jewellery will last a long time and certainly a lot longer than mass-produced items made using cheaper materials. I can recount plenty of stories of stones falling off, or chain links breaking back when I used to buy mass –produced jewellery. BUT this also means that the cost of materials for a handmade is going to make it more expensive, it simply costs more to buy the finest materials.
It seems an easier choice to me then when you think 'shall I pay £12 several times or £80 once for a handmade piece' that will last…but onwards.
Since the time it takes to make handmade jewellery is longer then as the saying goes 'time is money'. After all this is still a business, I need to pay a wage to myself, to staff (and I can tell you it's a lot lower than you think). Did you know 'Labour' is usually one of the highest costs if not the highest costs for a business? So I have to pay myself or my staff for more hours.
This doesn't mean like every business I don't try and cut costs but it will always be more for handmade jewellery. I don't have machines that can cut out 20 pieces in the time it takes me to cut out 4, it takes hours to lay down and fire enamels piece by piece. I could really fill several pages on this but I won't for your sanity and mine! But as you can see there isn't or shouldn't be a comparison between handmade and mass-produced. So far then the materials cost more, the time it takes to make the jewellery is longer.
I hate to harp on…. but aside from making the jewellery there is photographing it, adding to the website, writing the content, marketing the business, buying supplies, managing the emails, designing marketing materials, taking inventory, managing the accounts (Oh joy), buying new tools. And then of course there are the Overheads – Gas, electricity, internet, printing, business supplies. Are you tired yet?
Much of this has to be added to the cost of the jewellery (as percentage of it anyway), this is how all businesses run. And a lot of this you won't actually see so it isn't obvious, but it can make or break a business.
I used to baulk at the idea of 'Wearable Art' until I started doing this. But it IS just that, the designs have come from the artists, our creativity and pride is infused in every detail of a piece. Our care and attention shows in the craftsmanship of a piece. We all have stories to tell, why we make, what inspires us, we take you on a journey, we give you an experience not just a piece of jewellery.
And we are always trying to perfect and improve because we care about what we make and sell, what our customers think and feel, we really do want you to feel unique and special (I'll tell you a secret, it makes us feel unique and special in return).
Now you could go and buy jewellery at a department store but how unique is it really when there are a 100 of them?
Personally I strive to be as different from everyone else as I can (no offense!), I value my individuality and to me handmade gives me just that. I try to buy and support handmade as often as I can wherever I am – I finally get it.
Now you could say yes but this is just my opinion and you would be right, but then buying jewellery like buying anything else is subjective and it is of course your choice!
Although I have digressed at times during this blog it has only been to make the point as to why handmade jewellery is more expensive, I am hopeful that after reading this you will have a little more insight. It is more expensive because of everything I have written, our materials cost more but then you are getting the best and something that will last. That very uniqueness that attracts you to a piece of jewellery wouldn't exist if it weren't for the creativity of the artist. The time it takes to make a piece by hand is so much longer but then you get quality craftsmanship you wouldn't get on a mass-produced piece.
Fine Silver jewellery is softer than sterling silver, therefore you should always ensure that you don't wear your jewellery activities such as gardening, very heavy lifting or where there is likely hood of the jewellery catching as this may bend the silver. Silver jewellery should ideally also be removed before working with chemicals or photographic solutions as this can again cause tarnishing.
Although Fine silver should not tarnish as easily as Sterling silver due to its higher silver purity, it may still tarnish over time. Where there are Sterling silver components or chains they will more readily tarnish. Tarnishing can be caused by excess moisture in the skin, gasses in the air and a variety of other factors, however bringing back the shine is fairly easy! You can use a small amount of baking soda in water to soak the piece, then rinse under water and gently drying off. Or you can use the silver polish cloth included with all Secret Jewellery pieces to gently and lightly polish the piece to return it to its original shine.
Whilst enamel jewellery is hard wearing and cared for can last forever, it is in essence still powdered glass which has been fused onto the silver through heating, therefore you should take extra care when wearing it. Try to avoid dropping or hitting it against anything hard as this can chip at or break the enamel.
So don't forget with a little love and care your jewellery should last, and bring you joy for a very long time!
Chain length can make or break your style statement so I thought it might help to put together a quick reference guide for you.
As someone with a fairly slim neck I have often found necklaces and pendants can hang too low on my neckline at 18" yet make the perfect statement at 16" long. In my experience I've often found that necklaces and pendants come with a standard 18' chain which has meant replacing or shortening the chain for it to sit on my neck the way I liked it, and where the pendant or necklace really looked at its best.
Therefore choosing the right chain length should definitely be considered.
I hope the simple visual guide above will help you decide what sort of statement you want to make, and what lengths might suit you best.
At the Secret Jeweller you can opt for these lengths for many of the pieces available, in some instances the chain lengths may be part of the design so you may need to contact me to discuss alternative length adjustments.
I'm very excited here at the Secret Jeweller (who I lovingly refer to as SJ, though I do know Sj is not a person!). I'm just excited because I can finally share the brand with you and I love sharing.
It has taken me not a small amount of time, a few setbacks and well frankly just too much Earl Grey and Prosecco (not a combination I would recommend) to get here, but making everything by hand takes time.
Still here I am, with pieces from my Earth, Air, Water, Fire series, inspired by a lifelong love of mountains, forests and oceans (Though I'm also 'secretly' a city person).
I really hope to create jewellery that is special and unique because I truly want to celebrate those qualities in everyone around me, and I want anyone who wears my jewellery to feel special. That has been my aim from the beginning and something i'll always work to (I'm very focused like that!). You can read my profile to find out more.
So have a look around and i'll let you decide for yourselves, feel free to drop me a note or if you're interested in commissioning a piece i'm happy to help.
Also, I just got back from the studio and I can tell you there are more pieces coming, but as I said earlier creating art really does take time and i'd prefer not to rush things so remember to come back!
The beautiful and colorful art of Enamelling is actually an ancient technique dating as far back as the 2nd century BCE and involves decorating metal objects with thin layers of powdered or vitreous glaze to add colour. Bronze was a metal that featured frequently in the early forms of enamelling, from jewellery to vessels to swords, utensils and so much more - and you can see the many such relics in museums around the world today including the Natural History Museum here in London. Nowadays more so Copper, Silver and Gold are popular metals. The brilliant, vibrant colours are achieved through variations in oxides such as lead (still used today in leaded enamels) that lend colour to a clear base enamel known as Flux - what is not to love!
In cloisonné , thin fine silver or pure gold 'strips' a few millimeters high are curved and formed into a design or pattern to create "cells' for the enamel powders to sit in. These are then fused into a base of clear flux by fusing first the base flux layer, onto the metal, then laying the wires on top of the fused layer, re-firing and re-melting the enamel to capture the wires. The wire can also be soldered directly onto the metal.
Coloured enamel powders are then laid down into the cells layer by layer, each one is fired in between, cooled, then the next layer applied, building up until the layers reach flush with the tops of the wires. They are then 'sanded' down and polished, ready to be set into a jewel.
In champlevé instead of formed wired creating the cells for the enamel, cells are gouged out of the metal creating channels or depressions that are then filled with powdered enamel. In the case of champleve, the metal needs to be thicker than with Cloisonné to allow for removing metal.
Basse-Taille (low cut in French) is the technique of 'chasing' or engraving or in some way texturing the metal that is then enamelled with transparent or translucent enamels, creating amazing depth and variations in colours with the reflecting light over the textured undulations of the design.
This technique is designed to lend a stained glass affect, commonly 'cells' are either cut out of metal in a pattern, or a frame has strips of wire soldered to it to create a network of cells which are then filled with enamel and fired, the technique has not backing metal so the light shines directly through the glass like looking through a stained glass church window!
Here at The Secret Jeweller we use a combination of Champlevé, Basse-Taille and Cloisonné, we love the depth and movement that comes from creating textures using Basse-Taille and think it really brings out art to life!
Hi and welcome to the Secret jeweller (also lovingly known as SJ) blog. Hop on it's at times a humorous, Earl Grey and Prosecco-fuelled journey - though not together, that would be wrong. You can find guides on choosing chain lengths, read about why you should buy handmade, what is enamel anyway and why the 'Secret' Jeweller? Or you can just look around, feel free to leave feedback..most of all I hope you have found something good from visiting.


I remember seeing the WonderSwan in magazines as a kid & being jealous that I could not import one from Japan. Well it's been quite awhile and I now have acquired one. For the time this machine was amazing, it was sleek, stylist and thin. The battery pack was actually thicker than the system and used only 1 AA. It lasts quite a while too, which was a big scare to every other portable out there. The WonderSwan was also very inexpensive at the time. Which again, I was very jealous of Japan back then, funny how it's kind of turned around now.


Last week scientists spotted 101 geysers on Saturn's moon, thought about the possibilities of an 'impossible' space propulsion and more. See the best stories from the week here.

The Washington State Tree Fruit Association (WSTFA) released its forecast for the 2018 Washington state fresh apple crop today, predicting a fresh pack crop of 131 million standard 40-pound boxes of fresh apples, down 2% from the 2017 crop.
'Gala' is projected to be the most numerous variety in 2018 at 24% of production, with longtime leader 'Red Delicious' now projected to come in second at 21.5%. These varieties are followed by 'Fuji' at 13.5% and 'Granny Smith' at 13% of total production. This year 'Honeycrisp' is forecast to come in at 10.8% of the total crop and 'Cripps Pink' at 4.5%.
Organic apple production continues to increase, and is forecast to be 14% of the total, or 18.9 million boxes. However, the WSTFA notes that typically not all organic production is ultimately packed and marketed as organic.
This forecast is based on a survey of WSTFA members and represents the best estimate of the total volume of apples that will eventually be packed and sold on the fresh market — excluding product sent to a processor.
Apple harvest typically begins in August and continues into November. As a result, the WSTFA emphasizes this forecast is still subject to several months of variable weather, which can affect the final harvest total.
